Definitions
- the present invention relates to the field of dispensers. More specifically, the present invention relates to dispensers which are capable of accommodating different sizes of tissue rolls and tissue roll cores.
- Toilet tissue is usually manufactured and marketed in rolls. The rolls are attached to dispensers which are mounted on a wall. Toilet tissue rolls used in a commercial setting have core-diameters ranging from one to four inches, while household rolls generally have a more standard core diameter of about one and one-half inches.
- toilet tissue dispensers In a commercial setting, toilet tissue dispensers oftentimes support multiple rolls.
- Wall mounted devices for dispensing multiple tissue paper rolls are known in the art. Such rolls typically may support the axis of each roll either parallel to or perpendicular to a mounting wall.
- U.S. Pat. No. 3,294,329 describes a dispenser wherein tissue rolls are mounted in a side-by-side orientation, with the axis of each roll perpendicular to the wall of a washroom.
- U.S. Pat. No. 4,872,601 describes a dispenser wherein industrial sized rolls, as opposed to personal sized rolls, are mounted in a side-by-side orientation.
- a spindle is provided to support the various tissue rolls.
- Various spindle arrangements for wall-mounted dispensers exist in the marketplace. Such spindle arrangements may accommodate two, three or four rolls.
- a two-roll dispenser may have a movable top spindle which drops out of an enclosure either by pressing a button or alternatively being automatically tripped when the lower roll is depleted.
- Another multiple roll dispenser is in the form of a carousel that allows the user to rotate sequential rolls along the wall of the washroom.
- Other tissue dispensers such as that described in U.S. Pat. No. 4,807,823, have a top roll and a bottom roll holder, both of which have fixed spindles.
- An enclosure is provided over the top roll so that to the user cannot remove tissue sheets from the top roll until the bottom roll has been depleted.
- tissue roll The capacity of a tissue roll is dependent upon the size of the core diameter and roll width. Most commercial toilet tissue dispensers limit roll size versatility because each dispenser only accepts one core size and/or one tissue roll size. As a result, a dispenser that can accept various sized core diameters would allow a user to load a wide variety of commercial grade tissue rolls. By having one dispenser that can provide tissue from different sized rolls, the need to purchase a plurality of different dispensers to accommodate each core size is eliminated.
- U.S. Pat. No. 6,364,245 describes a tissue dispenser with adaptable spindle core support structures that may be used with at least two different diameter cores of toilet roll tissue.
- the core support structures project from and attach to the back wall of the dispenser.
- the supports are stationary and do not concurrently rotate with an engaged tissue core. A user pulling the tissue from the roll must exert enough effort to overcome any frictional resistance between the tissue core and the corresponding, stationary core support. As a result of the higher friction from a non-rotating core, tissue may prematurely break when pulled, causing inconvenience for a user.
- tissue dispenser having a means for accommodating tissue rolls of various inner core diameters.
- tissue dispenser wherein the support structure rotates with the roll.
- the benefits and advantages of the present invention are achieved by an improved tissue dispenser capable of accommodating tissue rolls having different inner core sizes and different outer diameters.
- the dispenser generally includes a base and a cover. Both the base and the cover have a side wall.
- the base of the dispenser has at least one spindle.
- a first spindle and a second spindle are provided.
- Each spindle extends from the base, and is rotatable relative to the base.
- Each spindle has an elongated shaft terminating at a tip distally from the base.
- the tips of the spindles are shaped to operatively engage outer knobs along the cover. In this manner, a user may rotate the spindles and supported tissue rolls by rotating the knobs external to the dispenser.
- the dispenser also has a plurality of sleeves interchangeably disposed on the shafts of the one or more spindles.
- Each sleeve comprises an elongated shaft with an inner diameter dimensioned to receive the shaft of the spindle.
- the sleeves optionally have slots to receive a corresponding spline of the spindle. In this way, rotational movement of the spindle imparts rotational movement to the sleeve.
- the sleeves have a plurality of fins radially disposed on the outer diameter.
- the fins have a width dimensioned to circumferentially support the inner diameter of a core of a tissue roll. In accordance with one aspect of the present invention, the widths of the fins for the sleeves vary so as to accommodate tissue rolls having different inner core sizes.
- the dispenser also preferably includes a door assembly.
- the door assembly is configured to selectively cover a tissue roll on either the first or the second side of the base.
- the door assembly is biased to a right side, and a door catch is provided to selectively hold the door assembly to a left side after a left tissue roll has been substantially exhausted.
- a plurality of snap fittings configured to releasably attach to the door assembly may also be provided.
- Each snap fitting has a different height to prevent the premature movement of the door assembly by the user from one side of the tissue dispenser to the other, depending upon the diameter of the core of the tissue rolls used.
- the selected snap fitting releasably attaches along a horizontal base of the door assembly.
- the dispenser preferably has an outer first knob and an outer second knob. Each knob is supported on the cover.
- the outer first and second knobs are aligned with the tips of the first and second spindles, respectively, such that rotation of the first knob causes the first spindle and supported sleeve to rotate, while rotation of the second knob causes the second spindle and supported sleeve to rotate.
- this invention provides a tissue dispenser comprising:
- each sleeve comprising an elongated shaft terminating at an end, the shaft having an inner diameter dimensioned to receive the shaft of the spindle, and an outer diameter, and wherein at least two of the plurality of sleeves are configured to support tissue rolls having cores of different inner diameters.

- a left roll 20 is seen exploded away from the base 200 . More specifically, a left roll 20 is exploded away from a left spindle 40 L on the left side of the base 200 .
- the exemplary left roll 20 comprises two aspects. First, the roll has a circular inner core 22 . Second, the roll 20 has tissue 24 wound over or around the core 22 . The core 22 serves as a central supporting member about which the tissue 24 is wound or rolled. The tissue roll 20 defines an outer diameter that must fit within the left side of the dispenser 100 .
- the tissue 24 of the tissue roll 20 is a substrate of airlaid, nonwoven fibers held together by a binding agent.
- a wide variety of natural and synthetic fibers are suitable for use as matrix fibers for the nonwoven tissue.
- Preferred matrix fibers are cellulosic fibers, though matrix fibers may also be synthetic fibers or a mixture of cellulosic and synthetic fibers.
- Cellulosic fibrous materials suitable for use in the dispenser 100 include both softwood fibers and hardwood fibers.
- the cellulose fiber for use as a matrix fiber has been derived from a source which is one or more of Southern Softwood Kraft, Northern Softwood Kraft, hardwood, eucalyptus, mechanical, pre- and post-consumer recycled wood fibers and rayon, or Southern Softwood Kraft, Northern Softwood Kraft, or a mixture thereof. Southern Softwood Kraft is most preferred.
- Binders suitable for use in the nonwoven material may be various bicomponent binder fibers or mixtures thereof, various latices or mixtures thereof, or bicomponent fibers or mixtures thereof in combination with various latices or mixtures thereof, which may be thermoplastic, thermosetting or a mixture thereof.
- the present invention is not limited by the type or composition of tissue 24 used.
- the dispenser 100 first includes a base 200 .
- the base 200 comprises a body 202 used to secure the base 200 to a supporting surface.
- the body 202 may be any plate, and preferably is a substantially planar body that supports tissue rolls 20 , 30 . Encompassing at least a portion of the body 202 is a side wall 204 .
- the wall 204 is integral to the body 202 and covers the rolls 20 , 30 for aesthetic and hygienic purposes.
- An opening 205 (seen in FIG. 3 ) is retained along the side wall 204 at the bottom of the body 202 to provide an access to the tissue rolls 20 , 30 by a user.
- the central plate 206 defines a vertical member that separates the left 20 and right 30 tissue rolls.
- the central plate 206 serves to prevent contamination between the rolls 20 , 30 and to isolate the right roll 30 while the left roll 20 is being used.
- the use of the central plate 206 is an optional feature.
- a pair of keyholes 208 are designed to mate with fingers 308 on the cover 300 .
- the keyholes interact with a lock 306 .
- a key 307 is shown for manipulating the fingers 308 .
- Each pivot arm 210 contains a pin opening which receives a pin 212 .
- the pin 212 provides a pivoting connection between the base 200 and the cover 300 .
- the base 200 also includes a plurality of connector openings 214 .
- the connector openings 214 are formed into the body 202 and are preferably oval in shape.
- Each connector opening 214 is designed to optionally receive a connector (not shown) such as a bolt or screw. In this manner, the base 200 may be secured to a vertical support surface such as a bathroom wall or stall (not shown).
- FIG. 3 presents an enlarged view of the base 200 of FIGS. 1 and 2 .
- the cover 300 has been removed from the base 200 for illustrative purposes. In this view, various features of the base 200 are more clearly seen. These include the body 202 , the side wall 204 , the central plate 206 , and the keyholes 208 . Also visible in FIG. 3 is an optional door assembly 220 .
- the door assembly 220 serves to limit a user's access to one side of the dispenser 100 or the other when the cover 300 is over the base 200 . The door assembly 220 would not be needed where the dispenser includes only a single tissue roll.
- the door assembly 220 first includes a horizontal base member 222 .
- the base member 222 is positioned along the right side of the base 200 . In this position, the user does not have access to a roll (not shown) which would be loaded on the right side of the dispenser 100 .
- the horizontal base 222 is designed to be slidable along the body 202 of the dispenser 100 .
- a handle 224 is provided below the horizontal base 222 of the door assembly 220 .
- a channel 225 is further provided along the body 202 in order to afford a track along which the horizontal base 222 may slide.
- the door assembly 220 further comprises a door stop 226 .
- the door stop 226 is a generally triangular piece secured to the horizontal door base 222 .
- the door stop 226 and connected horizontal base 222 are biased to be in the right side of base 200 .
- the biasing feature is preferably a spring (not shown), which urges the door stop 226 and base 222 to the right.
- the user may slide the door stop 226 and horizontal base 222 towards the left side of the dispenser 100 along channel 225 .
- the door stop 226 reaches the left side of the base 200 , it catches a door catch 228 in the body 202 .
- the biasing effect of the door assembly 220 is overcome and the door stop 226 and horizontal base 222 are maintained on the left side of the base 200 .
- the user may then access the tissue roll 30 on the right side of the dispenser 100 .
- the snap fitting 240 also defines a generally triangular member. In the embodiment of FIG. 3 , the snap fitting 240 fits upon a left end of the horizontal base 222 . The snap fitting 240 serves as a barrier to prevent a user from sliding the door stop 226 and connected base 222 until the left roll 20 is substantially exhausted.
- the snap fitting 240 is designed to be releasably engaged to the horizontal base 222 .
- snap fittings 240 of different sizes, i.e. different heights, may be employed. This, in turn, allows the dispenser 100 to functionally accommodate tissue roll sizes 20 , 30 of different outer diameters or different core sizes.
- FIGS. 4A and 4B provide perspective views of two different snap fittings 240 ′ and 240 ′′. It can be seen that snap fitting 240 ′ of FIG. 4A has a shorter height than snap fitting 240 ′′ of FIG. 4B . In this way, a maintenance person can control when the door assembly 220 can be moved from its right position to its left position, depending upon the diameter of the core 22 of the left tissue roll 20 . Thus, where the tissue roll 20 has a large core 22 and large outer diameter, a shorter snap fitting (such as fitting 240 ′) would be used. However, where the tissue roll 20 has a small diameter core 22 and a small outer diameter, then a taller snap fitting (such as fitting 240 ′′ of FIG. 4B ) would be used.
- the operation of the door assembly 220 could be inverted.
- the door assembly could be biased to the left side of the dispenser 100 , and the snap fitting 240 ′ or 240 ′′ could be keyed to the size of the right tissue roll 30 and core 32 . This is simply a designer's choice.
- the door assembly 220 remains positioned on the right side of the base.
- a large snap fitting (such as snap fitting 240 ′′) has been placed on the left side of the horizontal base 222 of the door assembly 220 . In this way, a tissue paper roll 20 having a smaller core 22 may be accommodated.
- the tissue dispenser 100 includes a cover 300 pivotally secured to the base 200 .
- the cover 300 includes a body 302 and a generally radial side wall 304 .
- An opening is once again preserved in the side wall 304 , which generally corresponds with the access opening 205 preserved by the side wall 204 of the base 200 .
- At opposing ends of the side wall 304 is a pair of pivot arms 310 .
- Pivot arms 310 generally correspond in position and function with pivot arms 210 of the base 200 .
- Each pivot arm 310 includes a pinhole which receives the pins 212 . In this manner, the pivot arms 310 of the cover 300 are pivotally secured to the pivot arms 210 of the base 200 .
- the cover 300 has been pivotally opened relative to the base 200 . In this way, the internal features of the base 200 and cover 300 are exposed. Further in this manner, a tissue roll such as left roll 20 may be loaded onto the base 200 .
- the left 20 and right 30 tissue rolls have been loaded onto left 40 L and right 40 R spindles (spindles seen in FIG. 3 ). Further, the cover 300 has been pivotally rotated into a locked position with the base 200 .
- a locking assembly is provided.
- the locking assembly is seen in FIG. 2 on the cover 300 and includes a lock 306 .
- the lock 306 operates with a cam (not shown) which transmits pivoting movement to a pair of fingers 308 in response to rotating action of a key 307 . This means that rotation of the key 307 within the lock 306 permits a maintenance person to manipulate the position of the fingers 308 .
- the fingers 308 mate with keyholes 208 of the base 200 . Closing the cover 300 against the base 200 ( FIG. 1 ) causes the fingers 308 to lock into the keyholes 208 in a manner known in the art.
- the maintenance person turns the lock 306 of the cover 300 , causing the fingers 308 to be released from the keyholes 208 .
- the cover 300 may then be swung open from its closed position in FIG. 1 to its opened position in FIG. 2 .
- the tissue rolls 20 , 30 are supported by left 40 L and right 40 R spindles.
- the spindles 40 L, 40 R are more clearly seen in the enlarged perspective view of FIG. 3 .
- the two spindles 40 L, 40 R are preferably identical in configuration and dimension.
- the spindles 40 L, 40 R are designed to freely rotate relative to the body 202 of the base 200 .
- a level of friction may be selectively applied between the spindles 40 L, 40 R and the body 202 in order to impose a degree of difficulty in the rotation of the supported tissue rolls 20 , 30 .
- FIG. 5 provides a rear perspective view of a spindle 40 R being moved into the base 200 . More specifically, an exemplary spindle 40 R is being inserted into a right opening 230 R of the body 202 of the base 200 . It can be seen that the spindle 40 R has a base 42 that is designed to fit into the right opening 230 R. The circumference of the base 42 defines a bearing surface for rotation within the right opening 230 R. The base 42 and connected spindle 40 R are secured to the body 202 by a locking washer 48 (seen in FIG. 7 ).
- the base 200 has a left opening 230 L. It is understood that the left opening 230 L will also receive a spindle (spindle 40 L) and a locking washer 48 . Each spindle 40 L, 40 R, in turn, will receive a core 22 , 32 of tissue rolls 20 , 30 respectively.
- FIG. 6 presents another enlarged view of the base 200 of FIG. 1 .
- the cover 300 has again been removed from the base 200 for illustrative purposes. It can be seen in this view that the left tissue roll 20 has been placed onto the left spindle 40 L. However, the roll 30 for the right spindle 40 R has been exploded away from the dispenser 100 . It can also be seen from FIG. 6 that the right spindle 40 R has a sleeve 50 positioned over its length. The sleeve 50 has a plurality of fins (seen at 58 in FIG. 7 ) which engage the core 32 of a tissue roll 30 when it is placed onto the spindle 40 R. This means that while a sleeve 50 cannot be seen over left spindle 40 L, it is present but obscured by the left roll 20 .
- sleeves 50 and connected fins 58 will receive cores 22 , 32 of the tissue rolls 20 , 30 .
- the sleeves 50 are preferably secured to the spindles 40 L, 40 R so that there is no relative rotational movement. Stated another way, when spindle 40 R rotates, the sleeve 50 and connected tissue roll 30 likewise rotate. Similarly, when spindle 40 L rotates, the sleeve 50 and connected tissue roll 20 likewise rotates. However, the locking washers 48 do not rotate, but secure the spindles 40 L, 40 R to the body 202 .
- FIG. 7 shows a perspective view an exemplary spindle 40 and an exemplary sleeve 50 .
- the sleeve 50 is exploded away from the spindle 40 . Relative features of the spindle 40 and the sleeve 50 are more clearly seen.
- the spindle 40 includes a base 42 , and an elongated shaft 43 that terminates at a tip 44 .
- the base 42 of the spindle 40 engages an opening (such as left opening 230 L) in the body 202 of the dispenser 100 .
- a circumference of the base 42 serves as a bearing surface within the body 202 of the base 200 .
- the shaft 43 of the spindle 40 extends outwardly from the body 202 of the base 200 .
- the shaft 43 preferably has a circular profile, although other profiles may be used.
- the shaft 43 terminates at a tip 44 .
- the tip 44 defines a smaller diameter than the shaft 43 . This permits the tip 44 to an end 54 of the sleeve 50 , as will be more fully described below.
- splines 46 engage mating slots 56 at the end 54 of the sleeve 50 .
- the end 54 of the sleeve defines a radially inward shoulder that includes slots 56 .

Description
- The present application claims priority under 35 U.S.C. §120 to a previous application filed in the United States. That application was filed on Jun. 6, 2006. The application was assigned Ser. No. 60/811,254 by the U.S. Patent and Trademark Office, and was entitled “Versatile Core Size Tissue Dispenser.” The provisional application is incorporated herein by reference in its entirety.
- 1. Field of the Invention
- The present invention relates to the field of dispensers. More specifically, the present invention relates to dispensers which are capable of accommodating different sizes of tissue rolls and tissue roll cores.
- 2. Background of the Invention
- Toilet tissue is usually manufactured and marketed in rolls. The rolls are attached to dispensers which are mounted on a wall. Toilet tissue rolls used in a commercial setting have core-diameters ranging from one to four inches, while household rolls generally have a more standard core diameter of about one and one-half inches.
- In a commercial setting, toilet tissue dispensers oftentimes support multiple rolls. Wall mounted devices for dispensing multiple tissue paper rolls are known in the art. Such rolls typically may support the axis of each roll either parallel to or perpendicular to a mounting wall. For example, U.S. Pat. No. 3,294,329 describes a dispenser wherein tissue rolls are mounted in a side-by-side orientation, with the axis of each roll perpendicular to the wall of a washroom. U.S. Pat. No. 4,872,601 describes a dispenser wherein industrial sized rolls, as opposed to personal sized rolls, are mounted in a side-by-side orientation.
- In commercial dispensers, a spindle is provided to support the various tissue rolls. Various spindle arrangements for wall-mounted dispensers exist in the marketplace. Such spindle arrangements may accommodate two, three or four rolls. A two-roll dispenser may have a movable top spindle which drops out of an enclosure either by pressing a button or alternatively being automatically tripped when the lower roll is depleted. Another multiple roll dispenser is in the form of a carousel that allows the user to rotate sequential rolls along the wall of the washroom. Other tissue dispensers, such as that described in U.S. Pat. No. 4,807,823, have a top roll and a bottom roll holder, both of which have fixed spindles. An enclosure is provided over the top roll so that to the user cannot remove tissue sheets from the top roll until the bottom roll has been depleted.
- The capacity of a tissue roll is dependent upon the size of the core diameter and roll width. Most commercial toilet tissue dispensers limit roll size versatility because each dispenser only accepts one core size and/or one tissue roll size. As a result, a dispenser that can accept various sized core diameters would allow a user to load a wide variety of commercial grade tissue rolls. By having one dispenser that can provide tissue from different sized rolls, the need to purchase a plurality of different dispensers to accommodate each core size is eliminated.
- U.S. Pat. No. 6,364,245 describes a tissue dispenser with adaptable spindle core support structures that may be used with at least two different diameter cores of toilet roll tissue. The core support structures project from and attach to the back wall of the dispenser. The supports are stationary and do not concurrently rotate with an engaged tissue core. A user pulling the tissue from the roll must exert enough effort to overcome any frictional resistance between the tissue core and the corresponding, stationary core support. As a result of the higher friction from a non-rotating core, tissue may prematurely break when pulled, causing inconvenience for a user.
- Therefore, there exists a need in the art for a tissue dispenser having a means for accommodating tissue rolls of various inner core diameters. A need further exists for a tissue dispenser that prevents the premature accessibility of one tissue roll before another roll is substantially exhausted, and that accommodates tissue rolls of different outer diameters. There further exists a need for such a tissue dispenser wherein the support structure rotates with the roll.
- The benefits and advantages of the present invention are achieved by an improved tissue dispenser capable of accommodating tissue rolls having different inner core sizes and different outer diameters. The dispenser generally includes a base and a cover. Both the base and the cover have a side wall.
- The base of the dispenser has at least one spindle. In one aspect, a first spindle and a second spindle are provided. Each spindle extends from the base, and is rotatable relative to the base. Each spindle has an elongated shaft terminating at a tip distally from the base. Preferably, the tips of the spindles are shaped to operatively engage outer knobs along the cover. In this manner, a user may rotate the spindles and supported tissue rolls by rotating the knobs external to the dispenser.
- The dispenser also has a plurality of sleeves interchangeably disposed on the shafts of the one or more spindles. Each sleeve comprises an elongated shaft with an inner diameter dimensioned to receive the shaft of the spindle. The sleeves optionally have slots to receive a corresponding spline of the spindle. In this way, rotational movement of the spindle imparts rotational movement to the sleeve. Finally, the sleeves have a plurality of fins radially disposed on the outer diameter. The fins have a width dimensioned to circumferentially support the inner diameter of a core of a tissue roll. In accordance with one aspect of the present invention, the widths of the fins for the sleeves vary so as to accommodate tissue rolls having different inner core sizes.
- The dispenser also preferably includes a door assembly. The door assembly is configured to selectively cover a tissue roll on either the first or the second side of the base. Preferably, the door assembly is biased to a right side, and a door catch is provided to selectively hold the door assembly to a left side after a left tissue roll has been substantially exhausted.
- A plurality of snap fittings configured to releasably attach to the door assembly may also be provided. Each snap fitting has a different height to prevent the premature movement of the door assembly by the user from one side of the tissue dispenser to the other, depending upon the diameter of the core of the tissue rolls used. Preferably, the selected snap fitting releasably attaches along a horizontal base of the door assembly.
- The dispenser preferably has an outer first knob and an outer second knob. Each knob is supported on the cover. The outer first and second knobs are aligned with the tips of the first and second spindles, respectively, such that rotation of the first knob causes the first spindle and supported sleeve to rotate, while rotation of the second knob causes the second spindle and supported sleeve to rotate.
- In another aspect, this invention provides a tissue dispenser comprising:
- (A) a base;
- (B) at least one spindle, the spindle having an elongated shaft extending from the base and a terminating at a tip distally from the base; and
- (C) a plurality of sleeves interchangeably disposed on the shaft of the spindle, each sleeve comprising an elongated shaft terminating at an end, the shaft having an inner diameter dimensioned to receive the shaft of the spindle, and an outer diameter, and wherein at least two of the plurality of sleeves are configured to support tissue rolls having cores of different inner diameters.
- In one aspect, the sleeves have different outer diameters dimensioned to support tissue rolls having cores of about 2.5 cm to about 11 cm in diameter. For instance, the plurality of sleeves may comprise (i) a first pair of sleeves, with each of the sleeves having outer diameters dimensioned to support tissue rolls having a core diameter of about 5.84 cm; and (ii) a second pair of sleeves, with each of the sleeves having outer diameters dimensioned to support tissue rolls having a core diameter of about 8.38 cm.
- In one embodiment, each of the plurality of sleeves further comprises at least one fin disposed on the outer diameter of the sleeve. The at least one fin has a width dimensioned to circumferentially support the core of a tissue roll. The at least one fin may comprise a plurality of fins radially disposed around the outer diameter of the shaft of the corresponding sleeve. For some sleeves, the fins provide the outer diameter of the sleeves used to support the tissue rolls.
- In one embodiment, the at least one spindle defines a single spindle. The single spindle is configured to rotate relative to the base, and to receive and support a tissue roll. The spindle may be configured to rotate relative to the base, and to receive and support a tissue roll having a core diameter of about 2.8 cm. In another embodiment, the at least one spindle defines a left and a right spindle, with each spindle receiving one of the plurality of sleeves for supporting a tissue roll.
- In one embodiment, the tissue dispenser further comprises:
- (D) a cover pivotally connected to the base for selectively covering the left and right sleeves and supported tissue rolls.
- The base may further comprise a side wall along the base having opposing ends, with each end of the side wall defining a pivot arm, and a pin disposed in each of the pivot arms to provide pivoting connections between the side walls and the cover.
- In one embodiment, the tissue dispenser further comprises:
- (E) a door assembly configured to selectively cover a tissue roll on either the left or the right side of the base.
- The door assembly may further comprise a horizontal base, and a handle for engaging the door assembly by a user. Preferably, the door assembly is biased to a first side of the tissue dispenser, and further comprises a door stop and a door catch disposed in the base of the tissue dispenser for releasably receiving the door stop and holding it on an opposing second side of the tissue dispenser.
- In one embodiment, the tissue dispenser further comprises:
- (F) a plurality of snap fittings configured to releasably attach to the door assembly, with each snap fitting having a different height to prevent the premature movement of the door assembly by the user from a first side of the tissue dispenser to a second side, depending upon the diameter of the core of the tissue rolls used.
- The snap fittings preferably attach releasably to the horizontal base of the door assembly.
- In one embodiment, the at least one spindle comprises a left spindle and a right spindle, and the tissue dispenser further comprises:
- (G) an outer left knob and an outer right knob each supported on the cover, with the outer left and right knobs being aligned with the tips of the left and right spindles, respectively, wherein (i) rotation of the left knob causes the left spindle and supported sleeve to rotate; and (ii) rotation of the right knob causes the right spindle and supported sleeve to rotate.
- In this instance, the tips of the left and right spindles each comprises a shaped surface that mates with an inner surface of the left and right knobs, respectively. Preferably, the inner surface of the left and right knobs further comprises a separate washer member.
- So that the manner in which the features of the present invention can be better understood, certain drawings are appended hereto. It is to be noted, however, that the drawings illustrate only selected embodiments of the inventions and are therefore not to be considered limiting of scope, for the inventions may admit to other equally effective embodiments and applications.

FIG. 1 presents a perspective view of adispenser 100 of the present invention, in one embodiment. The purpose of thedispenser 100 is to dispense tissue (such as toilet tissue) to a user. Thedispenser 100 is shown in a vertical orientation, ready for use. In operation, thetissue dispenser 100 is preferably secured to a vertical surface such as a bathroom wall or stall (not shown). - The
dispenser 100 includes abase 200, andcorresponding cover 300. Thebase 200 is secured to the vertical surface (not shown), while thecover 300 pivotally attaches to thebase 200. In one aspect, thetissue dispenser 100 dispenses a single roll of tissue. However, it is preferred that thedispenser 100 be a dual roll dispenser, permitting a pair of tissue rolls to be dispensed in sequence. Alternatively, thedispenser 100 may accommodate three or more tissue rolls. - The
illustrative dispenser 100 ofFIG. 1 is a two-roll dispenser. Thecover 300 is secured to the base 200 such that internal components of the two-roll dispenser 100 are not visible. However, a pair ofrolls cover 300. The rolls represent aleft roll 20 and aright roll 30. -
FIG. 2 demonstrates a perspective view of thedispenser 100 ofFIG. 1 , with thecover 300 being opened to expose thebase 200. No tissue roll is loaded onto thedispenser 100. However, aleft roll 20 is seen exploded away from thebase 200. More specifically, aleft roll 20 is exploded away from aleft spindle 40L on the left side of thebase 200. - It can be seen that the exemplary
left roll 20 comprises two aspects. First, the roll has a circularinner core 22. Second, theroll 20 hastissue 24 wound over or around thecore 22. Thecore 22 serves as a central supporting member about which thetissue 24 is wound or rolled. Thetissue roll 20 defines an outer diameter that must fit within the left side of thedispenser 100. - Preferably, the
tissue 24 of thetissue roll 20 is a substrate of airlaid, nonwoven fibers held together by a binding agent. A wide variety of natural and synthetic fibers are suitable for use as matrix fibers for the nonwoven tissue. Preferred matrix fibers are cellulosic fibers, though matrix fibers may also be synthetic fibers or a mixture of cellulosic and synthetic fibers. Cellulosic fibrous materials suitable for use in thedispenser 100 include both softwood fibers and hardwood fibers. Desirably, the cellulose fiber for use as a matrix fiber has been derived from a source which is one or more of Southern Softwood Kraft, Northern Softwood Kraft, hardwood, eucalyptus, mechanical, pre- and post-consumer recycled wood fibers and rayon, or Southern Softwood Kraft, Northern Softwood Kraft, or a mixture thereof. Southern Softwood Kraft is most preferred. - Binders suitable for use in the nonwoven material may be various bicomponent binder fibers or mixtures thereof, various latices or mixtures thereof, or bicomponent fibers or mixtures thereof in combination with various latices or mixtures thereof, which may be thermoplastic, thermosetting or a mixture thereof. However, it is understood that the present invention is not limited by the type or composition of
tissue 24 used. - Referring again to the
dispenser 100, and as noted previously, thedispenser 100 first includes abase 200. Thebase 200 comprises abody 202 used to secure the base 200 to a supporting surface. Thebody 202 may be any plate, and preferably is a substantially planar body that supports tissue rolls 20, 30. Encompassing at least a portion of thebody 202 is aside wall 204. In the arrangement ofFIGS. 1 and 2 , thewall 204 is integral to thebody 202 and covers therolls FIG. 3 ) is retained along theside wall 204 at the bottom of thebody 202 to provide an access to the tissue rolls 20, 30 by a user. - Within the
side wall 204 and central to thebody 202 is acentral plate 206. Thecentral plate 206 defines a vertical member that separates the left 20 and right 30 tissue rolls. Thecentral plate 206 serves to prevent contamination between therolls right roll 30 while theleft roll 20 is being used. The use of thecentral plate 206 is an optional feature. - Immediately above the
central plate 206 is a pair ofkeyholes 208. As will be discussed further below, thekeyholes 208 are designed to mate withfingers 308 on thecover 300. The keyholes interact with alock 306. Together thekeyholes 208,fingers 308 and lock 306 form a locking assembly to selectively lock thecover 300 to the base 200 so as to prevent user access. A key 307 is shown for manipulating thefingers 308. - At opposing ends of the
side wall 204 of the base 200 arepivot arms 210. Eachpivot arm 210 contains a pin opening which receives apin 212. As will be discussed further below, thepin 212 provides a pivoting connection between the base 200 and thecover 300. - The base 200 also includes a plurality of
connector openings 214. Theconnector openings 214 are formed into thebody 202 and are preferably oval in shape. Eachconnector opening 214 is designed to optionally receive a connector (not shown) such as a bolt or screw. In this manner, thebase 200 may be secured to a vertical support surface such as a bathroom wall or stall (not shown). -
FIG. 3 presents an enlarged view of thebase 200 ofFIGS. 1 and 2 . Thecover 300 has been removed from thebase 200 for illustrative purposes. In this view, various features of the base 200 are more clearly seen. These include thebody 202, theside wall 204, thecentral plate 206, and thekeyholes 208. Also visible inFIG. 3 is anoptional door assembly 220. Thedoor assembly 220 serves to limit a user's access to one side of thedispenser 100 or the other when thecover 300 is over thebase 200. Thedoor assembly 220 would not be needed where the dispenser includes only a single tissue roll. - The
door assembly 220 first includes ahorizontal base member 222. In the view ofFIG. 3 , thebase member 222 is positioned along the right side of thebase 200. In this position, the user does not have access to a roll (not shown) which would be loaded on the right side of thedispenser 100. Thehorizontal base 222 is designed to be slidable along thebody 202 of thedispenser 100. To accomplish horizontal movement, ahandle 224 is provided below thehorizontal base 222 of thedoor assembly 220. Achannel 225 is further provided along thebody 202 in order to afford a track along which thehorizontal base 222 may slide. - The
door assembly 220 further comprises adoor stop 226. Thedoor stop 226 is a generally triangular piece secured to thehorizontal door base 222. Thedoor stop 226 and connectedhorizontal base 222 are biased to be in the right side ofbase 200. The biasing feature is preferably a spring (not shown), which urges thedoor stop 226 andbase 222 to the right. However, when theleft tissue roll 20 is essentially exhausted, the user may slide thedoor stop 226 andhorizontal base 222 towards the left side of thedispenser 100 alongchannel 225. As thedoor stop 226 reaches the left side of thebase 200, it catches adoor catch 228 in thebody 202. In this manner, the biasing effect of thedoor assembly 220 is overcome and thedoor stop 226 andhorizontal base 222 are maintained on the left side of thebase 200. The user may then access thetissue roll 30 on the right side of thedispenser 100. - An additional optional feature of the
door assembly 220 is asnap fitting 240. The snap fitting 240 also defines a generally triangular member. In the embodiment ofFIG. 3 , the snap fitting 240 fits upon a left end of thehorizontal base 222. The snap fitting 240 serves as a barrier to prevent a user from sliding thedoor stop 226 andconnected base 222 until theleft roll 20 is substantially exhausted. - The snap fitting 240 is designed to be releasably engaged to the
horizontal base 222. In this way, snapfittings 240 of different sizes, i.e. different heights, may be employed. This, in turn, allows thedispenser 100 to functionally accommodatetissue roll sizes -
FIGS. 4A and 4B provide perspective views of twodifferent snap fittings 240′ and 240″. It can be seen that snap fitting 240′ ofFIG. 4A has a shorter height than snap fitting 240″ ofFIG. 4B . In this way, a maintenance person can control when thedoor assembly 220 can be moved from its right position to its left position, depending upon the diameter of thecore 22 of theleft tissue roll 20. Thus, where thetissue roll 20 has alarge core 22 and large outer diameter, a shorter snap fitting (such as fitting 240′) would be used. However, where thetissue roll 20 has asmall diameter core 22 and a small outer diameter, then a taller snap fitting (such as fitting 240″ ofFIG. 4B ) would be used. - It is noted that the operation of the
door assembly 220 could be inverted. In this respect, the door assembly could be biased to the left side of thedispenser 100, and the snap fitting 240′ or 240″ could be keyed to the size of theright tissue roll 30 andcore 32. This is simply a designer's choice. - It can be seen from the enlarged view of
FIG. 3 that thedoor assembly 220 remains positioned on the right side of the base. A large snap fitting (such as snap fitting 240″) has been placed on the left side of thehorizontal base 222 of thedoor assembly 220. In this way, atissue paper roll 20 having asmaller core 22 may be accommodated. - Referring again to
FIGS. 1 and 2 , thetissue dispenser 100 includes acover 300 pivotally secured to thebase 200. As with thebase 200, thecover 300 includes abody 302 and a generallyradial side wall 304. An opening is once again preserved in theside wall 304, which generally corresponds with the access opening 205 preserved by theside wall 204 of thebase 200. At opposing ends of theside wall 304 is a pair ofpivot arms 310. Pivotarms 310 generally correspond in position and function withpivot arms 210 of thebase 200. Eachpivot arm 310 includes a pinhole which receives thepins 212. In this manner, thepivot arms 310 of thecover 300 are pivotally secured to thepivot arms 210 of thebase 200. - In the perspective view of
FIG. 2 , thecover 300 has been pivotally opened relative to thebase 200. In this way, the internal features of thebase 200 and cover 300 are exposed. Further in this manner, a tissue roll such asleft roll 20 may be loaded onto thebase 200. In the perspective view ofFIG. 1 , the left 20 and right 30 tissue rolls have been loaded onto left 40L and right 40R spindles (spindles seen inFIG. 3 ). Further, thecover 300 has been pivotally rotated into a locked position with thebase 200. - In order to secure the
cover 300 to thebase 200, a locking assembly is provided. The locking assembly is seen inFIG. 2 on thecover 300 and includes alock 306. Thelock 306 operates with a cam (not shown) which transmits pivoting movement to a pair offingers 308 in response to rotating action of a key 307. This means that rotation of the key 307 within thelock 306 permits a maintenance person to manipulate the position of thefingers 308. In operation, thefingers 308 mate withkeyholes 208 of thebase 200. Closing thecover 300 against the base 200 (FIG. 1 ) causes thefingers 308 to lock into thekeyholes 208 in a manner known in the art. Later, when a maintenance person desires to open thecover 300, the maintenance person turns thelock 306 of thecover 300, causing thefingers 308 to be released from thekeyholes 208. Thecover 300 may then be swung open from its closed position inFIG. 1 to its opened position inFIG. 2 . - As indicated above, the tissue rolls 20, 30 are supported by left 40L and right 40R spindles. The
spindles FIG. 3 . The twospindles spindles body 202 of thebase 200. However, in one optional embodiment a level of friction may be selectively applied between thespindles body 202 in order to impose a degree of difficulty in the rotation of the supported tissue rolls 20, 30. -
FIG. 5 provides a rear perspective view of aspindle 40R being moved into thebase 200. More specifically, anexemplary spindle 40R is being inserted into aright opening 230R of thebody 202 of thebase 200. It can be seen that thespindle 40R has a base 42 that is designed to fit into theright opening 230R. The circumference of thebase 42 defines a bearing surface for rotation within theright opening 230R. Thebase 42 and connectedspindle 40R are secured to thebody 202 by a locking washer 48 (seen inFIG. 7 ). - It can also be seen from the rear perspective view of
FIG. 5 that thebase 200 has aleft opening 230L. It is understood that theleft opening 230L will also receive a spindle (spindle 40L) and a lockingwasher 48. Eachspindle core - Moving now to
FIG. 6 ,FIG. 6 presents another enlarged view of thebase 200 ofFIG. 1 . Thecover 300 has again been removed from thebase 200 for illustrative purposes. It can be seen in this view that theleft tissue roll 20 has been placed onto theleft spindle 40L. However, theroll 30 for theright spindle 40R has been exploded away from thedispenser 100. It can also be seen fromFIG. 6 that theright spindle 40R has asleeve 50 positioned over its length. Thesleeve 50 has a plurality of fins (seen at 58 inFIG. 7 ) which engage thecore 32 of atissue roll 30 when it is placed onto thespindle 40R. This means that while asleeve 50 cannot be seen overleft spindle 40L, it is present but obscured by theleft roll 20. - In operation,
sleeves 50 andconnected fins 58 will receivecores sleeves 50, in turn, are preferably secured to thespindles spindle 40R rotates, thesleeve 50 andconnected tissue roll 30 likewise rotate. Similarly, whenspindle 40L rotates, thesleeve 50 andconnected tissue roll 20 likewise rotates. However, the lockingwashers 48 do not rotate, but secure thespindles body 202. -
FIG. 7 shows a perspective view anexemplary spindle 40 and anexemplary sleeve 50. Thesleeve 50 is exploded away from thespindle 40. Relative features of thespindle 40 and thesleeve 50 are more clearly seen. - First, concerning the
spindle 40, it can be seen that thespindle 40 includes abase 42, and anelongated shaft 43 that terminates at atip 44. Thebase 42 of thespindle 40 engages an opening (such asleft opening 230L) in thebody 202 of thedispenser 100. A circumference of thebase 42 serves as a bearing surface within thebody 202 of thebase 200. - The
shaft 43 of thespindle 40 extends outwardly from thebody 202 of thebase 200. Theshaft 43 preferably has a circular profile, although other profiles may be used. Theshaft 43 terminates at atip 44. In the illustrative embodiment ofFIG. 7 , thetip 44 defines a smaller diameter than theshaft 43. This permits thetip 44 to anend 54 of thesleeve 50, as will be more fully described below. - Along the outer diameter of the
shaft 43 is one ormore splines 46. Thesplines 46 engagemating slots 56 at theend 54 of thesleeve 50. Theend 54 of the sleeve defines a radially inward shoulder that includesslots 56. Theslots 56 receive thespindles 46. In this manner, relative rotation of thespindle 40 and thesleeve 50 is prohibited. - The
tip 44 of thespindle 40 optionally includes an elastically formedcatch 55. Thecatch 55 is designed to interact with the radial, inwardly formed shoulder defining theend 54 of thesleeve 50. In this way thesleeve 50 is secured onto thespindle 40 during operation. Thecatch 55 can be released by a maintenance person by pressing thecatch 55 inward to clear theshoulder 54. - Along an outer diameter of the
spindle 40 is placed the lockingwasher 48. The lockingwasher 48 has a circular profile. Along its outer diameter aretabs 49 configured to snap into correspondingopenings 209 in thebody 202. In one optional arrangement, thewasher 48 provides a degree of friction against the rotation of the spindle. In such an arrangement (not shown), thewasher 48 may optionally be adjusted to increase or decrease the inertial rotation of thetissue roll - Referring again to the
tip 44 of thespindle 40, thetip 44 defines a shaped surface. In the preferred embodiment, the shape is a cross fabricated from two, transverse and intersecting ridges. As will be discussed further below, these ridges mate with a shaped surface on the inner surface of anexterior knob 330. - Turning next to the
sleeve 50, thesleeve 50 includes abase 52, and ashaft 53 terminating at theend 54. Theshaft 53 of thesleeve 50 defines a hollow member having an inner diameter configured to receive theshaft 43 of thespline 40. Further, theend 54 of thesleeve 50 includes an opening which receives thetip 44 of thespindle 40. As noted, theend 54 of thesleeve 50 defines an inward, radialshoulder having slots 56. Theslots 56 mate with thesplines 46 along the outer surface of theshaft 43 of thespindle 40. - As also seen in
FIG. 7 , thesleeve 50 includes a plurality offins 58. Thefins 58 are radially spaced about theshaft 53 of thesleeve 50. Preferably, thefins 58 frictionally engage the inner diameter of thecores fins 58 form an outer diameter that support the tissue roll core form eachroll - In accordance with the present invention,
sleeves 50 have different outer diameters. In one aspect, this is accomplished by providing different fin sizes.FIGS. 8A and 8B provide perspective views of two different embodiments ofillustrative sleeves 50′, 50″. Thesleeve 50′ ofFIG. 8A hasfins 58′ that are of a smaller width than thefins 58″ of thesleeve 50″ ofFIG. 8B . As withsnap fittings 240′, 240″, different sizes ofsleeves 50′, 50″ may be used depending upon the size of thetissue roll cores - In the commercial context, tissue roll cores typically run from about 2.5 cm to about 10.5 cm. Preferably, various sets of
sleeves 50 having different outer diameters between 1.5 cm and 11 cm are provided to accommodate core sizes within this range. In one aspect, one set ofsleeves 50′ forms an outer diameter that is 5.84 cm (2.3 inches) in diameter, while another set ofsleeves 50″ forms an outer diameter that is 8.38 cm (3.3 inches) in diameter. Further, it is preferred that the outer diameter of the supportingspindle 40 have a diameter of 2.8 cm (1.1 inches). In this way, at least three different core-diameters are readily accommodated. - In one aspect, the plurality of sleeves comprises a first set of sleeves, each sleeve having fins that form an outer diameter of about 2.8 cm (1.1 inches), a second set of sleeves with each sleeve forming an outer diameter of about 5.84 cm (2.3 inches), a third set of sleeves where each sleeve forms an outer diameter of about 8.38 cm (3.3 inches), and a fourth set of sleeves that each provide an outer diameter of about 10.16 cm (4 inches). However, any variation of diameters may be provided between 1.1 cm and 11 cm. Again, it is preferred that the outer diameter of the supporting
spindle 40 itself have a diameter of 2.8 cm (1.1 inches) to support the smallest cores. - An additional feature of the
tissue dispenser 100 is the ability of the user to rotate aspindle 40 and connectedsleeve 50 and tissue roll (20, 30) from outside of thedispenser 100. This may be done by rotatingouter knobs FIG. 1 ).FIG. 9 provides a perspective view of the inner surface of a portion of thecover 300 ofFIGS. 1 and 2 . Aknob 330R is shown exploded away from the right opening 330R of thecover 300. A rear of theknob 330R is seen. In addition, aninner washer 334 is seen exploded away from thecover 300. - It can be seen that the
knob 330R provides a mating relationship with thewasher 334. Thewasher 334, in turn, provides a mating relationship with thetip 44 of thespindle 40. In this way, rotation of theknob 330R from outside of thecover 300 imparts rotational movement to thespindle 40R. -
FIG. 10 is a perspective view of theouter knob 330R andinner washer 332 ofFIG. 9 . In this view, thecover 300 is removed for illustrative purposes. Thetip 44 of aspindle 40R is seen engaging correspondingridges 336 of theinner washer 334. In this way, rotational movement of theouter knob 330R transmits rotational movement to thespindle 40R. Thespindle 40R, in turn, rotates thesecured sleeve 50 and supportedtissue roll 30. - It is noted that in
FIGS. 9 and 10 , theright spindle 40R is presented. The arrangement is the same though for theleft spindle 40L and leftouter knob 330L. Also, nosleeve 50 is shown inFIGS. 9 and 10 . This is purely for illustrative purposes; thedispenser 100 operates withsleeves 50 onspindles - An
improved dispenser 100 is provided. While it will be apparent that the invention herein described is well calculated to achieve the benefits and advantages set forth above, it will be appreciated that the invention is susceptible to modification, variation and change without departing from the spirit thereof.
