BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates generally to substance dispensers. More particularly, the invention concerns an improved apparatus for dispensing metered amounts of powered material, such as infant formula, nutritional supplements and the like.
2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 1.98
A wide variety of dispensers for dispensing a number of different kinds of substances have been suggested in the past. More particularly, the prior art substance dispensers include dispensers for dispensing metered amounts of particulate materials, including granular and powdered materials such as condiments, powdered flavor concentrate, chemical reagents and nutritional supplements.
By way of example, U.S. Pat. No. 5,437,396 issued to Russillo, et al., discloses a dispenser apparatus for dispensing various types of condiments including salt, pepper, tea, coffee, spices, garlic and sugar. Similarly, U.S. Pat. No. 5,259,537 issued to Beers, et al., concerns a single dosage substance dispenser for dispensing powdered chemical reagents used in photometric analysis. The Beers, et al. dispenser includes a housing having a chamber formed therein for holding the substance to be dispensed and a discharge port that communicates with the chamber. A plunger is slidably mounted to the housing for extending through the chamber and into the discharge port. A spring is provided for urging the plunger to retract so that the seal portion of the plunger engages the discharge port and a receptacle portion is maintained in the chamber to collect the single dosage therefrom.
The patent to Robbins, et al., U.S. Pat. No. 5,490,615, concerns a condiment dispenser with variable quality control. The Robbins dispenser has the plunger which is pressed downwardly by the user to dispense condiments such as salt, pepper, sugar, spices, etc. An adjusting device can be set to determine a predetermined amount be dispensed by each stroke of the plunger.
U.S. Pat. No. 7,861,749 ('749), which was issued to the present inventor illustrates and describes the earlier form of dispenser unit, the improvement of which is described in the present application. This earlier form of dispenser unit has proven to be quite satisfactory, but exhibits a drawback that the improved dispenser of the present invention has uniquely corrected. More particularly, in the operation of the earlier form of the dispenser unit, certain of the powdered materials as, for example, powdered baby formula being dispensed by the unit would occasionally tend to become overly compacted, or to clump, thereby resulting in the uneven dispensing of the material. As will be discussed more fully in the paragraphs which follow, the improved dispenser of the present invention overcomes this deficiency by providing strategically located vibration motors that tend to mitigate against clumping of the powdered materials and function, along with the plunger of the device, to mitigate against compaction of the material and to ensure smooth and uniform dispensing of the materials into the powder-receiving container.
Another significant improvement to the dispenser of the '749 Patent resides in the provision of a material-receiving container of novel operation and design that takes the place of the powdered material-containing cartridge 34 illustrated and described in the '749 Patent. The construction and operation of this novel material-receiving container will be discussed in the paragraphs that follow.
Because of the pertinence, Applicant's earlier patent, U.S. Pat. No. 7,861,749 is hereby incorporated by reference as though fully set forth herein.
While the improved dispenser of the present invention is usable for dispensing a number of different types of powdered materials, it is especially useful for dispensing powdered baby formula. In this regard, a number of different types of infant formulas are readily commercially available in the United States and throughout the world. Because it is generally less expensive, infant formula in powdered form has become quite popular in recent years. Feeding with infant formula is practiced for a number of reasons, including the inability of the mother to produce sufficient breast milk, situations where the mother is taking medication that may adversely affect the quality of her breast milk and when the mother simply chooses not to breast-feed.
Powdered infant formula is generally sold in bulk and when used is typically removed from the bulk container in measured amounts and then mixed with specified amounts of water. The exact proportions specified on the product label must be used. Under-diluted formula can result in problems with the infant's digestive system and over-diluted formula will not provide adequate nutrition for the infant. It is this problem, among others, that the apparatus of the present invention seeks to overcome by providing an easy-to-use, highly reliable dispensing apparatus that automatically dispenses into the baby bottle precise quantities of infant formula.
The unique design of the dispenser of the present invention permits the user to load into the apparatus, baby bottles of various sizes and then to accurately dispense formula into the baby bottle without spillage. The plunger of the device, which can be operated with one hand if necessary, has an oscillating action that along with the vibration motors mitigates against compaction of the formula and prevents uneven dispensing of formula. Further, the plunger action builds negative pressure internally of the dispensing chamber during the down stroke to assist with the evacuation of formula from the dispensing cartridge of the device. As the internal volume in the dispensing chamber increases during the plunger down stroke, the resulting lowered internal pressure helps to uniformly draw formula from the dispensing cartridge.

BRIEF SUMMARY OF THE INVENTION

It is an object of the present invention to provide a dispenser for dispensing metered amounts of various types of materials, including baby formula, that is compact, easy-to-use and of an attractive design.
Another object of the invention is to provide a dispenser of the aforementioned character which can accommodate formula bottles of various sizes and in such a manner as to ensure that the formula bottle is directly integrated with the dispenser outlet so as to avoid spillage.
Another highly important object of the invention is to provide a dispenser of the character described which includes strategically located vibration motors that tend to mitigate against compaction and clumping of the powdered materials during the dispensing operation.
Another object of the invention is to provide a dispenser as described in the preceding paragraphs that includes a dispensing plunger that provides an oscillating action which, along with the vibration motor, prevents compaction of the formula and ensures even dispensing of the formula into the formula bottle.
Another object of the invention is to provide a dispenser of the character described in the preceding paragraphs in which the action of the dispensing plunger creates a negative pressure internally of the dispensing chamber of the dispenser so as to assist in the uniform withdrawal of formula from the pre-filled cartridge.
Another object of the invention is to provide a substance dispenser that dispenses powdered material, such as baby formula, from a pre-filled dispenser unit, or soft cartridge, that can be quickly and easily inserted into the material-receiving component of the dispenser.
Another object of the invention is to provide a substance dispenser of the character described in the preceding paragraph in which the pre-filled dispenser unit, or soft cartridge, can be quickly and easily opened after it has been positioned within the material-receiving component of the dispenser so as to effectively preclude contamination of the formula contained within the cartridge.
Another object of the invention is to provide a substance dispenser in which the material-receiving component of the dispenser is provided with a removable top so that, if desired, the removable top can be removed and powdered material such as baby formula from a bulk container can be quickly and easily poured, ladled or otherwise removed from the bulk container and deposited into the material-receiving component of the dispenser.
Another object of the invention is to provide a dispenser as described in the preceding paragraphs in which a single, measured portion of powdered formula is dispensed each time the dispensing plunger is actuated.
Another object of the invention is to provide a dispenser as described in the preceding paragraph that includes a volume control subassembly that enables a predetermined volume of powdered formula to be dispensed into the formula bottle.
Another object of the invention is to provide a dispenser of the type described in which the parts can be easily assembled and disassembled for ease of washing.
The foregoing and other objects of the invention are realized by the dispenser apparatus of the invention as more fully described in the paragraphs which follow.

DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings and particularly to FIGS. 1 and 2, one form of the improved dispenser apparatus of the present invention for dispensing powered material into a container, such as a formula bottle “B” is there shown and generally designated by the numeral 30. The dispenser apparatus here comprises a housing 32 having a base portion 32 a and an upper portion 32 b. Upper portion 32 b includes a closure wall 34 having at least one locating protuberance 35 and an opening 36, the purpose of which will presently be described (see also FIG. 6).
As best seen by referring to FIG. 6, a container support base 38 is connected to housing 32 for supporting the container, or formula bottle “B”. The support base is movable through a distance “D” between a first position shown by the dotted lines in FIG. 6 and a second position shown by the solid lines in FIG. 6. Biasing means shown here as a coil spring 40 that is housed internally of housing 32, functions to continuously urge the container support base 38 toward the first position shown by the dotted lines in FIG. 6. In the present form of the invention, the upper end 40 a of the spring is interconnected with the vibration motor support 41 and the lower end 40 b of the spring is interconnected with the connector portion 38 a of support base 38. In operation, the support base moves telescopically along a guide rod 42 that is housed within the housing 32. With the construction thus described, formula bottles of various sizes can readily be operably interconnected with the dispenser in the manner indicated in the drawings.
Removably connected to the upper portion 32 b of housing 32 in the manner best seen in FIG. 6 of the drawings is a material-receiving container 44 for receiving, in various forms, the powdered material to be dispensed. In the preferred form of the invention, container 44 comprises a bottom wall 44 a, a side wall 44 b having a material dispensing opening 45, and a removable cap 44 c that is removably connected to the upper portion of side wall 44 b. As illustrated in FIG. 2, after removal of cap 44 c, a soft cartridge “SC” containing a predetermined amount of powdered material can be conveniently inserted into the internal chamber 44 d of the container 44. Soft cartridge “SC” is provided with a side opening “O” (FIG. 3A) that is sealed by a sealing tab “T” that can be removed after the cartridge is in position within internal chamber 44 d.
It is to be understood that rather than using soft cartridge “SC”, the powdered material to be dispensed can be obtained from a bulk package and, once the cap 44 c is removed, can be poured, ladled, or otherwise deposited into the internal chamber 44 d of the container in whatever quantity that may be desired by the user.
As indicated in FIGS. 6 and 7, to correctly position the material-receiving container 44 relative to housing 32, bottom wall 44 a is provided with at least one opening 44 o that receives the previously identified protuberance 35 and a connector protuberance 49 that is constructed and arranged to be received within the previously identified opening 36 formed in the top wall 34 of housing 32. As indicated in the drawings, when the material-receiving container 44 is correctly positioned relative to housing 32, the outlet 45 of the container is indexedly aligned with the inlet of the novel material-dispensing assembly 54 of the invention, the character of which will presently be described. As shown in FIG. 7, a locking plate assembly 55, which is carried on wall 34, releasably receives protuberance 49. The locking plate assembly, which is similar to that described in incorporated-by-reference U.S. Pat. No. 7,861,749, is constructed and arranged so that by sliding the locking plate 55 a of the locking plate assembly from a first position to a second release position, the protuberance 49 will be released and the material-receiving container can be separated from the housing 32 for cleaning or replacement.
Referring particularly to FIG. 6, the important powdered material-dispensing assembly 54 here comprises a dispensing housing 56 having a powdered material chamber 57 having an inlet 57 a that is in communication with container outlet 45. As shown in FIG. 6, powdered material chamber 57 has an outlet 57 b that is in communication with the inlet “I” of the formula bottle “B”.
Forming a highly novel feature of the apparatus of the present invention is a material dispensing plunger sub-assembly, which is generally designated in the drawings by the numeral 58. Plunger sub-assembly 58, which is interconnected with the dispensing housing 56, comprises an elongated shaft 60 having an upper portion 60 a and a lower portion 60 b. By pushing downwardly on the finger engaging head portion 61, shaft 60 can be moved within the powdered material holding chamber 58 from the first position shown by the dotted lines in FIG. 5A to the second position shown by the solid lines in FIG. 5A.
Affixed proximate the lower portion 60 b of the shaft 60 is a uniquely configured, powdered material-dispensing component 64. In a manner presently to be described, material-dispensing component 64 functions to accurately dispense metered amounts of powdered material from powdered material chamber 57 into the formula bottle “B”.
Forming another highly novel feature of the present invention is oscillating means for oscillating the powdered material contained within powdered material chamber 57 as the material is dispensed into the formula bottle. This novel oscillating means functions to agitate the powdered material contained within chamber 57 and to release the powdered material from the chamber in an evenly distributed circular pattern into the formula bottle.
Referring particularly to FIGS. 4, 5 and 5A, this important oscillating means here comprises, in addition to shaft 60 and material dispensing component 64, a collar 6 that is affixed to elongated shaft 60 proximate the upper portion 60 a thereof. As best seen in FIGS. 5 and 5A, collar 66 is provided with a pair of oppositely disposed guide pins 68 that extend outwardly therefrom. Guide pins 68 are closely received within generally serpentine-shaped guide channels 70 a formed in a pair of oppositely disposed guide members 70 that are connected to housing 32 proximate the upper portion thereof. For a purpose presently to be described, a coil spring 72 circumscribes the intermediate portion of elongated shaft 60 so that the coil spring is disposed between collar 66 and the powdered material dispensing component 64. With this construction, as the shaft 60 is pushed downwardly in the direction of the arrow 67 of FIG. 5 against the urging of the coil spring 72, the guide pins 66 will travel along the serpentine guide channels 70 a thereby causing an oscillating, generally circular-shaped motion to be imparted to the powdered material-dispensing component 64 as indicated by the arrows 69 and 71 of FIGS. 5 and 5A.
In using the dispenser apparatus, the powdered material-containing soft cartridge SC is first inserted into chamber 44 b of the material-receiving container 44 in the manner illustrated in FIGS. 2 and 6 of the drawings.
With the formula bottle “B” in position on the support base 38 in the manner illustrated in FIG. 6 and with the soft cartridge “SC” in position within chamber 44 b of container 44, the user can move the sealing tab “T” upwardly by gripping the upper margin “T−1” of the sealing tab (see FIGS. 2 and 3A). With the sealing tab removed, the powdered medicament can flow through outlet “O”, into chamber 44 b and outwardly of opening 45 into chamber 58 of the powdered material-dispensing assembly 54.
To dispense a predetermined amount of formula into the formula bottle, the user need only push downwardly on the palm-engaging head portion 61 of the shaft 60. This downward movement of the shaft from the position shown by the dotted lines in FIG. 5A to the position shown by the solid lines in FIG. 5A will result in an oscillating movement of the powdered material-dispensing component 64 within the lower portion of chamber 57 in the manner previously described, which will cause the powdered material to flow evenly into the formula bottle.
Additionally, as previously mentioned, the downward movement of the dispensing plunger creates a negative pressure internally of the dispensing chamber of the dispenser so as to assist in the uniform withdrawal of formula from the pre-filled cartridge. More particularly, as shown in FIG. 5B of the drawings, palm-engaging head 61 includes a passageway 61 a that communicates with a reduced diameter passageway 60 c formed in the upper portion of shaft 60. Passageway 60 c, in turn, communicates with a cross-bore 60 d formed in the upper portion of the shaft. With this construction, the downward movement of the shaft will result in a decrease in pressure which assists in drawing the powdered material from the soft cartridge via outlet 45. However, when the user removes his or her palm from the palm-engaging head portion, passageway 61 a will be open to atmosphere, permitting pressure equalization to occur via the cross-bore 60 d and the reduced diameter passageway 60 c.
An extremely important feature of the improved dispenser of the present invention resides in the provision of first and second vibration motors 80 and 81 that are connected to the lower surface of top wall 34 of housing 32 in the manner illustrated in FIGS. 6 and 7 of the drawings. As previously mentioned, these vibration motors are strategically located proximate outlet 45 so as to impart a controlled vibration to internal chamber 44 d of material-receiving container 44 in a manner to mitigate against compaction and clumping of the powdered materials as the materials flow through outlet 45. While the vibration motors can take various forms, vibration motors 80 and 81 are battery-operated and are operably interconnected with a battery 84 by means of wires 80 a and 81 a respectively (see FIG. 6). Battery 84, which is of a character well understood by those skilled in the art and is readily commercially available, is disposed within the lower portion of housing 32.
The novel and important vibration motors 80 and 81 of the present invention are of a character well understood by those skilled in the art and are readily commercially available from several sources, but vibration motors that are sold by Shenzhen Kinmore Motor Co, Ltd. of Shenzhen, Guangdong, China have proven to be quite satisfactory for the intended purpose.
After filling the bottle “B”, the bottle can be removed from base 38 and the contents thereof then intermixed with water or other liquid.
When the soft cartridge “SC is empty, it can be easily removed from the container 44 and, if desired, container 40 can be disconnected from housing 32 for cleaning.
Referring next to FIGS. 8 and 8A, an alternate form of the improved dispenser apparatus of the present invention is there shown and generally designated by the numeral 87. This form of the improved dispenser apparatus is similar in many respects to that illustrated in FIGS. 1 through 7 and like numerals are used in FIGS. 8 and 8A to identify like components. Unlike the earlier described embodiments of the invention, dispenser apparatus 88 includes a novel portion control assembly that can be used to dispense a precise, predetermined volume of the powdered material into a container, such as the formula bottle “B”. The dispenser apparatus 87 here comprises a housing 88 that is similar in construction to the earlier described housing 32 and includes an upper portion 88 a having a closure wall 90. Closure wall 90 is provided with at least one locating protuberance 92 and an opening 94, the purpose of which will presently be described. As before, housing 88 supports the container, or formula bottle “B”, which, as in the earlier described embodiments, is movable between a lower position and an upper position. With this construction formula, bottles of various sizes can readily be operably interconnected with the dispenser.
Removably connected to the upper portion 88 a of housing 88, in the manner best seen in FIG. 8A of the drawings, is a material-receiving container 44 for receiving the powdered material to be dispensed. Material-receiving container 44 is substantially identical in construction and operation to that previously described herein and includes a bottom wall 44 a, a side wall 44 b having a material dispensing opening 45, and a removable cap (not shown in FIG. 8A) that is removably connected to the upper portion of side wall 44 b.
In using the apparatus of this latest form of the invention, the powdered material to be dispensed is obtained from a bulk package and, once the closure cap is removed, can be poured, ladled, or otherwise deposited into the internal chamber 44 d of the container in whatever quantity that may be desired by the user.
To correctly position the material-receiving container 44 relative to housing 88, bottom wall 44 a is provided with at least one opening that receives the previously identified protuberance 35 and a connector protuberance 49 that is constructed and arranged to be received within the previously identified opening 94 formed in the top wall 90 of housing 88. As indicated in the drawings, when the material-receiving container 44 is correctly positioned relative to housing 88, the outlet 45 of the container is indexedly aligned with the inlet of the novel material-dispensing assembly 100 of the invention, the character of which will presently be described. As in the earlier described embodiment of the invention, a locking plate assembly releasably receives protuberance 49. The locking plate assembly is constructed and arranged so that by sliding the locking plate of the locking plate assembly from a first position to a second release position, the protuberance 49 will be released and the material-receiving container can be separated from the housing 88 for cleaning or replacement.
Referring particularly to FIG. 8A, the important powdered material-dispensing assembly 100 here comprises a dispensing housing 102 having a powdered material chamber 104 having an inlet 104 a that is in communication with container outlet 45. As shown in FIG. 8A, powdered material holding chamber 104 has an outlet 104 b (FIG. 8A) that is in communication with the inlet “I” of the formula bottle “B”.
Forming a highly novel feature of the apparatus of this latest form of the invention is a material-dispensing plunger sub-assembly, which is generally designated in the drawings by the numeral 108. Plunger sub-assembly 108, which is interconnected with the dispensing housing 102, comprises an elongated shaft 110 having an upper portion 110 a and a lower portion 110 b. By pushing downwardly on the finger engaging head portion 111, shaft 110 can be moved within the powdered material holding chamber 104 against the urging of a coil spring 113, which circumscribes shaft 110, from the first upper position to the second lower position.
Affixed proximate the lower portion 110 b of the shaft 110 is a uniquely configured, powdered material-dispensing and portion control assembly 114. In a manner presently to be described, assembly 114 functions to accurately dispense a predetermined volume of powdered material from powdered material holding chamber 104 into the formula bottle “B”. Powdered material-dispensing and portion control assembly 114 includes a housing 116 having a top portion 116 a, a threaded bottom portion 116 b and a side portion 116 c that interconnects the top and bottom portions. Top, bottom, and side portions 116 a, 116 b and 116 c cooperate to define a generally cylindrically-shaped internal chamber 119 having a known volume “V” (FIG. 8). Connected to top portion 116 a is a disk-like pusher member 118 that is also connected to the bottom portion of shaft 110. Threadably interconnected with bottom portion 116 b of the housing 116 is a closure cap 120 that closes the lower portion of the internal chamber. Removably receivable within internal chamber 119 through an opening 119 a is a plurality of generally cylindrically-shaped chamber volume determining inserts, each being of a known volume. In the drawings, two chamber volume determining inserts 122 and 124 are depicted. However, it is to be understood that in using this latest form of the invention, any number of inserts of a known volume can be used.
In using the apparatus of this latest form of the invention, the user must first determine the desired portion of formula that is to be dispensed into the bottle “B”. As previously mentioned, the portion of formula that is to be dispensed can be varied by varying the number of volume determining inserts that are disposed within chamber 119. In the configuration shown in FIG. 8A of the drawings, after removing closure cap 120, two inserts, namely inserts 122 and 124, have been inserted into chamber 119 through opening 119 a. With the inserts in position within chamber 119, the volume remaining within the chamber is the cylindrically-shaped volume identified in FIG. 8A as “V−1”. During the bottle filling operation, the formula contained within material-receiving container 44 will flow into volume “V−1” via outlet 45 and inlet 104 a of material chamber 104. Next, as the shaft 110 is pushed downwardly against the urging of the coil spring 113 by a force exerted on finger engaging head portion 111, the housing 116 will be moved downwardly into the bottle and the formula contained within chamber “V−1” will flow evenly into the bottle through the circumferentially spaced apart outlets formed in the side portion of the housing.
If the user desires to dispense a larger volume of formula into the bottle, closure cover 120 can be removed and one or both of the inserts can be removed, thereby controllably varying the volume remaining within chamber 119 that can accept formula flowing from the material-receiving container 104.
As in the earlier described embodiments of the invention, this latest embodiment includes the important first and second vibration motors 80 and 81 that are connected to the lower surface of top wall 90 of housing 88 in the manner illustrated in FIG. 8A of the drawings.
Having now described the invention in detail in accordance with the requirements of the patent statues, those skilled in this art will have no difficulty in making changes and modifications in the individual parts or their relative assembly in order to meet specific requirements or conditions. Such changes and modifications may be made without departing from the scope and spirit of the invention, as set forth in the following claims.
