Description
- This application is a divisional of and claims priority benefit under 35 U.S.C. § 120 from U.S. Patent Application No. 10/990,792, filed on Nov. 17, 2004, which claims the priority benefit under 35 U.S.C. § 119(e) of U.S. Provisional Application No. 60/520,351, filed on Nov. 17, 2003, and entitled “RECLOSABLE BAG VACUUM SYSTEM,” and U.S. Provisional Application No. 60/576,980, filed on Jun. 4, 2004, and entitled “VACUUM APPARATUS FOR BUILT IN VACUUM SUCTION SYSTEMS TO EVACUATE AIR FROM RECLOSABLE FOOD STORAGE SYSTEM,” each of which is hereby incorporated by reference in its entirety.
- 1. Field of the Invention
- The present invention generally relates to vacuum sealing. More particularly, the present invention relates to using a vacuum source for removing air from a container.
- 2. Description of the Related Art
- Vacuum sealing of containers is a widely used technique for food preservation and storage. In general, food or other articles are placed within a specialized container from which air is evacuated through a vacuum sealing system. Conventional vacuum sealing systems generally include a vacuum source and a container sealing device, such as a bag welder. These systems also generally include a one-way valve usable with the container such that air may be removed from the container without the air flowing back in.
- Many conventional vacuum sealing systems are bulky and complex and require the purchase of specialized equipment and/or proprietary containers. For example, many vacuum sealing systems function only with specialized containers, such as customized jars or single-use plastic bags. When using the single-use bags, the vacuum sealing system often uses a heating portion to weld the bag opening shut. After the bags are opened, they can no longer be reused for vacuum sealing and are usually discarded. The repeated purchase of these customized containers can be expensive and burdensome for the user. Thus, there is room for improvement in vacuum sealing technology useful for those who desire an apparatus that has a more straightforward manner of use and that does not require the use of customized containers.
- Accordingly, one aspect of the present invention involves a device for facilitating vacuum sealing using a central in-house vacuum system. The device comprises an elongated air inlet nozzle having a tubular end configured to be inserted into a resealable container. The device further comprises a hollow intermediate section having a first port for communicating with a central in-house vacuum system and a second port for communicating with the nozzle. The device also includes an inline contamination filter located between the nozzle end and the first port of the intermediate section. The contamination filter generally permits air flow through the nozzle and the intermediate section but greatly reduces the likelihood of contaminants from entering the central in-house vacuum system through the nozzle end.
- Another aspect of the present invention involves a device for use in vacuum sealing a resealable container. The device comprises a cover plate generally adapted to attach to a wall port of a central vacuum system. The device further comprises an intermediate portion having an inlet port and an outlet port that communicates with the cover plate. The device also comprises an elongated air inlet portion having a tubular end, a connector end and a lumen. The connector end is moveably attached to the intermediate portion, and the lumen communicates with the inlet port. A contamination filter is located in at least one of the cover plate, the intermediate portion and the air inlet portion. The device also comprises an actuator generally configured to activate the central vacuum system such that air is drawn in through the air inlet portion when the tapered end of the inlet portion is moved in a substantially downward direction.
- Another aspect of the present invention involves an apparatus for use in vacuum sealing a resealable container. The apparatus comprises a vacuum source and an intermediate portion having a first port in communication with the vacuum source. The intermediate portion further comprises a second port. The apparatus also comprises an elongated air inlet portion having a tapered end, a connector end and a lumen extending between the tapered end and the connector end. The connector end couples to the intermediate portion such that the lumen communicates with the second port. The tapered end of the inlet portion is oriented in a downward direction such that the tapered end is vertically lower than the connector end when the apparatus is in use. A contamination filter is disposed in at least one of the intermediate portion and the air inlet portion.
- Another aspect of the present invention involves a device for facilitating vacuum sealing using a central in-house vacuum system. The device comprises an elongated air inlet portion having a tubular end configured to be inserted into a resealable container. The device also includes an intermediate section having a first port adapted to communicate with the central in-house vacuum system and a second port in communication with the inlet portion. A collection chamber is generally disposed between the first port and the second port. The intermediate portion further comprises a mounting plate configured to attach to a substantially planar surface.
- Another aspect of the present invention involves a method for vacuum sealing an article in a flexible, resealable container. The method includes placing an article within a flexible, resealable container having an opening. An elongated air inlet portion, which communicates with a central in-house vacuum, is inserted into the opening. The opening is then substantially sealed around the inlet portion. The method further includes triggering the central in-house vacuum system to withdraw air from the flexible, resealable container through the inlet portion. The inlet portion is then removed from the flexible, resealable container. The flexible, resealable container is then substantially sealed with the article contained therein.
- Another aspect of the present invention involves an apparatus for use in vacuum sealing a resealable container. The apparatus comprises means for accessing the interior of a flexible, resealable container. The apparatus further includes means for communicating with a wall port of a central vacuum system and means for coupling the accessing means to the communicating means such that air is drawn through the accessing means when the central vacuum system is active. The apparatus also includes means for substantially impeding contaminants from entering the central vacuum system through the accessing means and the communicating means. The substantially impeding means is disposed in at least one of the accessing means, the communicating means and the coupling means. The apparatus also comprises means for activating the central vacuum system in response to a particular movement of the accessing means.
- These and other features, aspects and advantages of the present invention will now be described with reference to the drawings of several preferred embodiments, which embodiments are intended to illustrate and not to limit the invention. The drawings comprise 14 figures.

FIGS. 1-10 , avacuum sealing apparatus 30 is shown. The illustratedvacuum sealing apparatus 30 is specifically adapted for use in removing air from containers. In a preferred embodiment, thevacuum sealing apparatus 30 is configured to remove air from resealable containers. In a more preferred embodiment, thevacuum sealing apparatus 30 is configured to remove air from flexible, resealable containers, such as for example, but without limitation, ZIPLOC® or GLAD® zipper-sealed bags. In other arrangements, thevacuum sealing apparatus 30 is configurable to remove air from a wide variety of containers, such as bags, jars, canisters and the like. - The
vacuum sealing apparatus 30 is advantageously adapted to communicate with a vacuum source. The vacuum source provides enough suction to draw air from a container and through at least a portion of thevacuum sealing apparatus 30. Preferably, the vacuum source is independent of, or external to, thevacuum sealing apparatus 30. For example, the vacuum source may comprise a central in-house vacuum system, a vacuum pump, a fan, or the like. For exemplary purposes, thevacuum sealing apparatus 30 will be described first with reference to use with a central in-house vacuum system. In some arrangements, a dedicated vacuum source can be connected to thevacuum sealing apparatus 30. - With reference to
FIG. 1 , the illustratedvacuum sealing apparatus 30 generally comprises aninlet portion 32 and anintermediate portion 34. Theinlet portion 32 is advantageously adapted to be inserted into aresealable container 33. As illustrated, theinlet portion 32 is generally of a tubular structure having a lumen that extends through theinlet portion 32. Theinlet portion 32 couples to theintermediate portion 34 such that the lumen of theinlet portion 32 communicates with a port of theintermediate portion 34. - As used herein, the term “tubular” includes its ordinary broad meaning, which includes a hollow structure, of any shape or cross-section, having at least two openings that allow for the passage of a liquid, solid and/or gas. For example,
FIG. 1 depicts thetubular inlet portion 32 as having an elongated, substantially cylindrical structure. In other arrangements, thetubular inlet portion 32 can take the form of a duct and/or can include a polygonal cross-section, an elliptical cross-section, combinations of the same or the like. - The illustrated
intermediate portion 34 further comprises achamber body 36, anelongated connector 38 and acover plate 40. Theintermediate portion 34 advantageously comprises at least one common passageway that extends through each of thechamber body 36, theelongated connector 38 and thecover plate 40, such that air may flow therethrough. In a preferred configuration, thechamber body 36 comprises an inlet port that communicates with the lumen of theinlet portion 32. - Furthermore, the
cover plate 40 preferably comprises an outlet port and couples to a wall port of an in-house vacuum system. In such a configuration, the in-house vacuum system can be used to draw air in through theinlet portion 32 and theintermediate portion 34 in order to vacuum seal a container. - The
intermediate portion 34 of the illustratedvacuum sealing apparatus 30 is configured to mount to a substantially planar surface. For example, theintermediate portion 34 is mountable on a substantially horizontal surface, such as underneath a cabinet, a counter, cupboard, or other like surface. In other arrangements, theintermediate portion 34 can be mounted to a substantially vertical surface, such as a backsplash or a wall. Furthermore, thewall plate 40 is configured to mount to a wall surface having a wall port of an in-house vacuum system. In other configurations, thevacuum sealing apparatus 30 is portable or can stand in an upright position. - In one arrangement, the
vacuum sealing apparatus 30 further comprises a filter that substantially reduces or eliminates contaminants, such as dust and debris, from the in-house vacuum system from traveling though thevacuum sealing apparatus 30 and out the inlet portion 32 (e.g., into the container being vacuum sealed). Furthermore, the filter generally impedes food, liquid, or other materials, which are stored in a container to be vacuum sealed, from entering the in-house vacuum system through thevacuum sealing apparatus 30. Preferably, the filter comprises an inline contamination filter that allows for the flow of air through thevacuum sealing apparatus 30 and that substantially reduces the flow of liquid and/or other particles out of thevacuum sealing apparatus 30. As will be appreciated, one or more filters can be disposed in one more locations within theinlet portion 32 and/or theintermediate portion 34. -
FIG. 1 further depicts thevacuum sealing apparatus 30 having theinlet portion 32 in a substantially vertical, or a deployed, position. In particular, the lumen of theinlet portion 32 is directed in a substantially downward direction. Such an orientation of theinlet portion 32 allows a user to keep the opening of the container to be vacuum sealed in a substantially upward orientation, which reduces the likelihood of materials inside the container falling out during the vacuum sealing process. -
FIG. 2 illustrates theinlet portion 32 in an elevated or substantially horizontal position. In one arrangement, theinlet portion 32 is oriented in such a position when the in-house vacuum system is in an off or non-operating state such that air is not drawn in through thevacuum sealing apparatus 30. Such a position also advantageously decreases the amount of space occupied by thevacuum sealing apparatus 30 when it is not in use. - In one configuration, movement of the
inlet portion 32 from the substantially horizontal position (as shown inFIG. 2 ) to the substantially vertical position (as shown inFIG. 1 ) activates the in-house vacuum system. As a result, air is drawn in through theinlet portion 32 so as to permit vacuum sealing. Likewise, movement of theinlet portion 32 back to the horizontal position deactivates the in-house vacuum system. In another configuration, to activate the in-house vacuum system, the user pulls the inlet portion 32 a certain amount while theinlet portion 32 is in the substantially vertical position. - With reference to
FIG. 3 , the illustratedinlet portion 32 further comprises a nozzle having atapered end 42, anelongated body 44 and aconnector 46. Thetapered end 42 facilitates the insertion of theinlet portion 32 in container openings. In addition, thetapered end 42 allows for the user to gradually remove theinlet portion 32 from the container while preventing a substantial amount of air from flowing into the container. - The illustrated
elongated body 44 preferably comprises a tubular structure. In one configuration, theelongated body 44 comprises a rigid material, such as, for example, a plastic or a light-weight metal. In other configurations, the elongated body 24 comprises a flexible material, such as a rubber or the like. Such flexibility allows a user more freedom in orienting the container to be vacuum sealed. Theelongated body 44 also provides for varying depths of insertion of theinlet portion 32 into containers of various sizes and/or shapes. - Furthermore, the illustrated
inlet portion 32 comprises a plurality of inlet holes 45 extending through theelongated body 44 from an outside surface of thebody 44 to a lumen extending through thebody 44. These inlet holes 45 provide for multiple locations in which air can be drawn in through theinlet portion 32. In other configurations, theinlet portion 32 may not include the inlet holes 45, or the inlet holes 45 may be selectively closeable by the user. - The
connector 46 couples theinlet portion 32 to theintermediate portion 34. In one configuration, theconnector 46 allows for movement of theinlet portion 32 with respect to theintermediate portion 34. Preferably, theconnector 46 is rotatable so as to allow theinlet portion 32 to move with at least one degree of freedom, such as between a substantially vertical position and a substantially horizontal position, as described above. For example, theconnector 46 may comprise a hinge or other pivoting mechanism. In other arrangements, theconnector 46 comprises a multi-axial configuration or a polycentric configuration allowing for multiple degrees of movement of theinlet portion 32. - In yet other arrangements, the
inlet portion 32 is in a fixed position with respect to theintermediate portion 34. In such an arrangement, thetapered end 42 of theinlet portion 32 preferably points in a substantially downward direction. As described above, this downward orientation helps reduce the likelihood of materials from falling out of the containers to be vacuum sealed and/or reduce the flow of contaminants into theinlet portion 32. - Although the
inlet portion 32 is described above with respect to particular arrangements, a wide variety of other configurations can be used. For example, theintermediate portion 34 may further comprise a spring or other similar retraction device that causes theinlet portion 32 to automatically retract from a substantially vertical position to a substantially horizontal position when theinlet portion 32 is not in use. In other arrangements, theinlet portion 32 may comprise a telescoping nozzle that allows for extension and retraction of theinlet portion 32, or theinlet portion 32 can be removably coupled to theintermediate portion 34, such as by a snap-on feature, for example. This removability facilitates cleaning and/or replacement of theinlet portion 32. For example, thevacuum sealing apparatus 30 may comprise multipleinterchangeable inlet portions 32 that are adapted to be used in different vacuum sealing environments, such as with different containers. - With continued reference to
FIG. 3 , the illustratedchamber body 36 of theintermediate portion 34 further comprises a mountingplate 48 usable to secure thevacuum sealing apparatus 30 to a substantially planar surface, as described previously. For example, the mountingplate 48 may use adhesives, screws, bolts, hooks, or other like securing devices and/or materials for attaching the mountingplate 48 to a surface. The illustrated mounting plate comprisesholes 49 for this purpose. - The
chamber body 36 further comprises amain housing 50 and anaccess cap 52. In one configuration, themain housing 50 forms or encompasses a collection chamber, such as a catch basin or a spillage chamber, usable to collect excess materials that are drawn in through theinlet portion 32. Removal of theaccess cap 52 facilitates user access to the collection chamber for cleaning and other maintenance.FIG. 4 further illustrates thechamber body 36 with theaccess cap 52 removed from anopening 59. - With reference to
FIG. 5 , theinlet portion 32 is again depicted in a substantially vertical, or deployed, orientation. In particular, thetapered end 42 of theinlet portion 32 is positioned vertically lower than theconnector 46, and theelongated body 44 is in a substantially vertical orientation.FIG. 5 further illustrates theinlet portion 32 coupled to theintermediate portion 34 through therotatable connector 46. In addition,FIG. 5 depicts the plurality of inlet holes 45 extending through theelongated body 44 of theair inlet portion 32. -
FIG. 6 illustrates a side cross-sectional view of theinlet portion 32 and thechamber body 36 of theintermediate portion 34. The illustratedinlet portion 32 further comprises alumen 54 that extends the length of theelongated body 44. The illustratedinlet portion 32 couples to thechamber body 36 such that thelumen 54 communicates with aninlet port 56 of thechamber body 36. - As described above, the
chamber body 36 further comprises acollection chamber 58 that provides a location in which contaminants, such as liquids or particles, may accumulate when passing into thechamber body 36. As illustrated, theinlet port 56 is advantageously located at an elevated position with respect to a bottom portion of thecollection chamber 58. Such a location helps prevent or impede food or liquid that is inadvertently drawn in through theinlet portion 32 and theinlet port 56, and that may accumulate in thecollection chamber 58, from returning into theinlet port 56 or substantially blocking theport 56. - As illustrated, the
chamber body 36 also comprises anexhaust port 60 that allows for air drawn in through theinlet port 56 to exit thechamber body 36. Theexhaust port 60 preferably communicates with theelongated connector 38. Furthermore, theexhaust port 60 is advantageously located at an elevated position with respect to a bottom portion of thecollection chamber 58. For example, the illustratedexhaust port 60 is located on the side of thecollection chamber 58. Such positioning helps prevent or impede contaminants that may accumulate in thecollection chamber 58 from being drawn into theelongated connector 38 and, in turn, into the vacuum source. This also helps remove larger particles and/or drops of liquid from air flowing through thecollection chamber 58. - In another arrangement, the
inlet port 56 and/or theexhaust port 60 can be located at the top of the collection chamber such that the opening of the port is oriented in a generally downward direction. In yet another arrangement, theexhaust port 60 can include baffles, screens, or the like usable to substantially impede particles and/or liquid from entering theexhaust port 60. - With continued reference to
FIG. 6 , thechamber body 36 further comprises theopening 59 that is closed by theaccess cap 52. As discussed previously, theaccess cap 52 is preferably at least partially removable to facilitate user access to thechamber body 36. In particular, removing theaccess cap 52 allows the user to remove accumulated contaminants from thecollection chamber 58. The access cap can be connected to the chamber body through a threaded or friction coupling, a snap fit, or the like. In another configuration, theaccess cap 52 is located on other portions of thechamber body 36. For example, theaccess cap 52 can be located at the bottom of thecollection chamber 58. In yet other configurations, thechamber body 36 comprises another apparatus or device, such as a slideable window, that facilitates cleaning of thechamber body 36. - Although described with reference to particular arrangements, a wide variety of alternative configurations are useable with the
vacuum sealing apparatus 30. For example, thechamber body 36 may further comprise a filter, as described above, located downstream from thecollection chamber 58. For example, the filter can be disposed within theexhaust port 60 or theconnector 38. In yet other configurations, thechamber body 36 may comprise a one-way stopper configured to substantially impede the movement of materials between theinlet portion 32 and thechamber body 36. For example, the one-way stopper can be located within or near theinlet port 56 and may be used in combination with the above-described filter. - With reference now to
FIGS. 7 and 8 , the illustratedcover plate 40 is in communication with acentral vacuum system 69 and comprises anadapter 62 for coupling theelongated connector 38 to a mountingportion 64. The illustrated mountingportion 64 comprises a disk-shaped surface having a flat side and an opposing, substantially convex side. The flat side of the mountingportion 64 facilitates attachment of the mountingportion 64 to a variety of planar surfaces, such as a wall. In particular, the mountingportion 64 is preferably configured to attach to a portion of a wall having an in-house vacuum system port. In one arrangement, thecover plate 40 can be substituted for a conventional in-house vacuum system cover plate or outlet cover. In such an arrangement, thecover plate 40 advantageously couples to existing wall port contacts or switches that control the operation of the in-house vacuum system. As a result, the operation of thevacuum sealing apparatus 30 is used to activate the in-house vacuum system during the vacuum sealing process. - The illustrated
cover plate 40 further comprises aremovable access cap 66. With reference toFIG. 8 , removal of theaccess cap 66 facilitates access to afilter 68 and to anoutlet port 70. In one embodiment, thefilter 68 comprises an inline contamination filter that prevents or impedes contaminants, such as dust or debris, from entering thevacuum sealing apparatus 30 through theoutlet port 70, which communicates with the in-house vacuum system. Thefilter 68 preferably allows for the flow of air but prevents or impedes the flow of liquids or particles through theoutlet port 70. Thefilter 68 is also preferably removable such that a user can periodically examine, clean and/or replace thefilter 68 to enable better performance of thevacuum sealing apparatus 30. - Although the
filter 68 is disclosed with reference to a particular configuration, a wide variety of alternative filters may be used with thevacuum sealing apparatus 30. For example, thefilter 68 may comprise a hydrophilic material that substantially impedes or prevents the passage of water. In another configuration, thefilter 68 may comprise plurality of narrow passageways arranged in a labyrinth-type configuration. These passageways may allow for the passage of air but may impede particles or liquids from passing therethrough. In yet other configurations, a similar filter can be disposed within theinlet portion 32, thechamber body 36 or theelongated connector 38 instead of, or in combination with, thefilter 68 in thecover plate 40. - With reference to
FIGS. 9A and 9B , thevacuum apparatus 30 is shown having thecover plate 40 located in a position below thechamber body 36.FIG. 9A depicts theinlet portion 32 in a retracted position, andFIG. 9B depicts theinlet portion 32 in a deployed position. Thus, differing positions between thecover plate 40 and thechamber body 36 can be used. -
FIG. 10 illustrates a bottom view of thevacuum apparatus 30 with a bottom portion of thechamber body 36 removed to show components within thechamber body 36. In particular,FIG. 10 depicts anactuator 71 usable to control the operation of the vacuum source, such as the in-house vacuum system. As shown, theactuator 71 is an electrical switch and further comprises acontact arm 72 and acontact pad 74. Theactuator 71 is further coupled to theinlet portion 32 such that rotation of theelongated body 44 about theconnector 46 causes a corresponding movement of theactuator 71. In particular, when theelongated body 44 of theinlet portion 32 is rotated to a substantially vertical position, aprotrusion 76 comes in physical contact with thecontact arm 72 and causes thecontact arm 72 to touch thecontact plate 74. This contact between thecontact arm 72 and thecontact plate 74 creates an electrical connection that causes the vacuum source, such as an in-house vacuum system, to turn on. Likewise, when theelongated body 44 is rotated back to a substantially horizontal position, as is shown inFIG. 10 , thecontact arm 72 separates from thecontact plate 74 and breaks the electrical connection, which causes the vacuum source to cease operating. - In yet other configurations, the
actuator 71 may comprise a manual switch, one or more sensors, or the like. Theactuator 71 may also be configured to couple to existing contacts or switches of the in-house vacuum system, such as in a conventional wall port, or theactuator 71 may communicate through wireless channels, such as radio frequency (RF) communication, with the vacuum source. - Furthermore, the
vacuum sealing apparatus 30 may comprise a variable control that allows the user to manage how much air is being drawn through thevacuum sealing apparatus 30. For example, the variable control may adjust the size of one of more passageways or ports of thevacuum sealing apparatus 30, which may include, for example, thelumen 54, theinlet port 56, theexhaust port 60 and/or theoutlet port 70. In one embodiment, the level of vacuum varies with the position of theinlet portion 32 relative to thechamber body 36. The variability can be achieved mechanically (e.g., flow constriction) or electrically (e.g., regulating the power of the vacuum source). - For exemplary purposes, a preferred method of use of the
vacuum sealing apparatus 30 with a resealable container will now be described. The user inserts thetapered end 42 ofinlet portion 32 in a container to be vacuum sealed. For example, theinlet portion 32 can be inserted in the opening of a zipper-type, resealable bag that contains food items. The depth of insertion may depend on the size of the bag and the properties of its contents. Once theinlet portion 32 is inserted into the bag opening, the user forms a substantial seal around theinlet portion 32 by closing the bag opening around theinlet portion 32. - Once the bag is substantially sealed around the
inlet portion 32, the user then pulls theinlet portion 32 forward or downward to activate the in-house vacuum system. In some configurations, theinlet portion 32 can be moved into a substantially downward direction before placing thetapered end 42 into the bag. As the in-house vacuum system evacuates air from the bag, the user slowly slides the bag down theinlet portion 32 while keeping enough downward pressure on theinlet portion 32 to keep the in-house vacuum system activated. The tapered shape of theinlet portion 32 allows the user to gradually seal the opening of the bag while moving the bag down theinlet portion 32. - Once the air is substantially removed from the bag, the user releases the downward pressure on the
inlet portion 32, which deactivates the in-house vacuum system. The user preferably slides the bag completely off theinlet portion 32 and seals the remaining bag opening to prevent unwanted air from returning into the bag. Once the bag is removed from theinlet portion 32, the inlet portion is returned into the substantially horizontal position. In configurations wherein theinlet portion 32 comprises an automatic retraction device, such a spring, theinlet portion 32 automatically returns to the horizontal position when the user no longer exerts pressure on theinlet portion 32. - As can be seen, the above-described method advantageously provides for a substantial “hands free” vacuum sealing process. That is, the user may vacuum seal a container without substantial use of his or her hands to hold and/or manipulate the
vacuum sealing apparatus 30. Instead, the user is able to hold and secure the container throughout the vacuum sealing process. - Furthermore, the
vacuum sealing apparatus 30 does not require the use of specialized bags or containers and allows for repeated vacuum sealing of resealable containers, such as zipper-type bags. This is because thevacuum sealing apparatus 30 need not puncture or heat seal the bag during the vacuum sealing process. - With reference now to
FIGS. 11A and 11B , anothervacuum sealing apparatus 130 is shown that is arranged and configured in accordance with certain features, aspects and advantages of the present invention. To simplify the description, components will not be redescribed in detail if they were described above. Rather, the components in the embodiment ofFIGS. 11A and 11B will be given a reference numeral that retains the same last two digits as the reference numeral used in the embodiment ofFIGS. 1-10 , and the last two digits will be preceded with a numeral “1.” Thus, thevacuum sealing apparatus 130 generally corresponds to thevacuum sealing apparatus 30 with certain differences that will be illuminated in the following discussion. - The
vacuum sealing apparatus 130 advantageously is self-contained and does not require an external vacuum source, such as an in-house vacuum system. With particular reference toFIG. 11A , thevacuum sealing apparatus 130 comprises aninlet portion 132 and anintermediate portion 134, which further comprises achamber body 136 and aconnector 138. Thechamber body 136 further includesholes 149 for securing the vacuum sealing apparatus to a surface such as, for example, a wall, a cabinet, a cupboard, a shelf or the like. - In contrast to the
vacuum sealing apparatus 30 ofFIGS. 1-10 , thevacuum sealing apparatus 130 comprises avacuum source 180. For example, the vacuum source may comprise a vacuum pump, a fan, or other apparatus or device usable to create air flow. Thevacuum source 180 preferably draws air in through theinlet portion 132 and out exhaust vents 182. In one configuration, thevacuum source 180 is powered by an AC power source, such as through a conventional electrical outlet. In another configuration, thevacuum source 180 is powered through a DC power source, such as by one or more batteries. - The
vacuum sealing apparatus 130 also preferably comprises at least one contamination filter (not shown) similar to thefilter 68 described previously. The contamination filter can be located within theinlet portion 132, thechamber body 136, or theconnector 138. - As described previously with respect to the
vacuum sealing apparatus 30, theinlet portion 132 can also be configured to move between a substantially horizontal position (shown inFIG. 11A ) and a substantially vertical position (shown inFIG. 11B ). - Furthermore, movement of the
inlet portion 132 may activate thevacuum source 180 such that air is drawn through theinlet portion 132. In one arrangement, slightly pulling theinlet portion 132 along the direction of the body of theinlet portion 132 activates thevacuum source 180. For example, pulling theinlet portion 132 can trigger an actuator, such as an electrical switch, within thevacuum source apparatus 130. Such an actuator can be advantageously located at a position proximate to the coupling of theinlet portion 132 to theintermediate portion 134. In yet other arrangements, movement of theinlet portion 132 from a substantially horizontal position to a substantially vertical position activates thevacuum source 180. Likewise, movement of theinlet portion 132 back to the horizontal position deactivates thevacuum source 180. - Although described with reference to particular arrangements, a wide variety of alternative devices or methods can be used to activate the
vacuum source 180. For example, a sensor or a switch can be located near the end of theinlet portion 132. When a container is brought near to or in contact with the end of theinlet portion 132, thevacuum source 180 begins operating. Likewise, when the container is removed from theinlet portion 132, thevacuum source 180 ceases operation. In yet other arrangements, thevacuum sealing apparatus 130 comprises a manual switch that the user activates and deactivates to control the functioning of thevacuum source 180. - As shown in
FIGS. 11A and 11B , thevacuum sealing apparatus 130 optionally comprises alight source 184 that provides illumination in the area used for vacuum sealing. Thelight source 184 is preferably configured such that contaminants, such as liquids, that accumulate in thechamber body 136 do not interfere with the function of thelight source 184. - Although the
vacuum sealing apparatus 130 is described above with respect to particular arrangements, a wide variety of alternative configurations are contemplated. For example, thevacuum sealing apparatus 130 can be configured to stand alone in an upright position, such as on the top of a counter, instead of mounting underneath a surface. In yet other configurations, thevacuum sealing apparatus 130 is portable. - In one arrangement, the method of using the
vacuum sealing apparatus 130 is similar to the above-disclosed methods of using thevacuum sealing apparatus 30. - With reference now to
FIGS. 12 and 13 , an embodiment of avacuum sealing apparatus 230 is illustrated that is arranged and configured in accordance with certain features, aspects and advantages of the present invention. Once again, to simplify the description, components will not be redescribed in detail if they were described above. Rather, the components in the embodiment ofFIGS. 12 and 13 will be given a reference numeral that retains the same last two digits as the reference numeral used in the embodiments ofFIGS. 1-11B , and the last two digits will be preceded with a numeral “2.” Thus, thevacuum sealing apparatus 230 generally corresponds to thevacuum sealing apparatus 30 and thevacuum sealing apparatus 130 with certain differences that will be illuminated in the following discussion. - As shown, the
vacuum sealing apparatus 230 comprises aninlet portion 232 and anintermediate portion 234. The illustratedintermediate portion 234 further compriseschamber body 236 and aconnector 238. Thechamber body 236 preferably comprises a tubular body made of a semi-flexible material, such as a plastic or rubber. - The
connector 238 is preferably adapted to couple to avacuum source port 290. In particular, the illustratedvacuum source port 290 comprises a wall port for an in-house vacuum system. Furthermore, coupling theconnector 238 to thevacuum source port 290 advantageously triggers the operation of the in-house vacuum system by activating at least one contact, such as an electrical switch, generally used in conventional in-house vacuum system wall ports. - Although described with reference to one arrangement, the
vacuum sealing apparatus 230 can be used with a wide variety of vacuum sources, such as, for example, household vacuum cleaners, portable vacuum systems, vacuum pumps, fans and the like. In yet other configurations, theconnector 238 can be customized to couple to various vacuum sources, or multiple connectors or adapters can be used in place of, or in combination with, the illustratedconnector 238. - With reference to
FIG. 13 , the illustratedvacuum sealing apparatus 230 further comprises afilter 268. Similar to thefilter 68 of thevacuum sealing apparatus 30, thefilter 268 is preferably an inline contamination filter that substantially reduces or eliminates the flow of particles and/or liquid between the vacuum source and thevacuum sealing apparatus 230. Preferably, thefilter 268 is removable so as to permit cleaning and/or replacement. Although the illustratedfilter 268 is disposed within theconnector 238, it is to be understood that thefilter 268 can be disposed in any location within thevacuum sealing apparatus 230 that allows for the blocking of particles or liquids. In yet other arrangements, thefilter 268 can be located within thevacuum source port 290. - In one arrangement, the method of using the
vacuum sealing apparatus 230 is similar to the above-disclosed method of using thevacuum sealing apparatus 30. The difference between the two methods is primarily at the beginning of the vacuum sealing process. When using thevacuum sealing apparatus 230, the user first couples theconnector 238 of thevacuum sealing apparatus 230 to thevacuum source port 290. In one arrangement, this coupling causes the vacuum source to begin operating. In other arrangements, the user can manually control the operation of the vacuum source. Either prior to or after the vacuum source begins operating, the user positions theinlet portion 232 in a container, such as a resealable bag, to be vacuum sealed. The user then uses thevacuum sealing apparatus 230 to remove the air from the container in a manner substantially similar to the method of using thevacuum sealing apparatus 30. To deactivate the vacuum source, the user can decouple theconnector 238 from thevacuum source port 290 or use other available means for deactivation, such as a switch located on thevacuum sealing apparatus 230. - With reference now to
FIG. 14 , an embodiment of avacuum sealing apparatus 330 is illustrated that is arranged and configured in accordance with certain features, aspects and advantages of the present invention. Once again, to simplify the description, components will not be redescribed in detail if they were described above. Rather, the components in the embodiments ofFIG. 14 will be given a reference numeral that retains the same last two digits as the reference numeral used in the embodiment ofFIGS. 1-13 , and the last two digits will be preceded with a numeral “3.” Thus, thevacuum sealing apparatus 330 generally corresponds to thevacuum sealing apparatus 30, thevacuum sealing apparatus 130 and thevacuum sealing apparatus 230 with certain differences that will be illuminated in the following discussion. - As shown, the
vacuum sealing apparatus 330 comprises aninlet portion 332 and anintermediate portion 334. The illustratedintermediate portion 334 further comprises achamber body 336 and aconnector 338. Thechamber body 336 preferably comprises a tubular body made of a rigid material, such as for example, a plastic or light-weight metal. - Similar to the
connector 238 ofFIGS. 12 and 13 , theconnector 338 is preferably adapted to couple to avacuum source port 390, such as thewall port 390 of an in-house vacuum system. In other arrangements, theconnector 338 can be used with household vacuum cleaners, portable vacuum systems, vacuum pumps, fans and/or the like. In yet other configurations, theconnector 338 can be customized to couple to various vacuum sources, or multiple connectors or adapters can be used in place of, or in combination with, the illustratedconnector 338. - With reference to
FIG. 14 , the illustratedvacuum sealing apparatus 330 further comprises afilter 368. Similar to thefilter 68 of thevacuum sealing apparatus 30, thefilter 268 is preferably an inline contamination filter that substantially reduces or eliminates the flow of particles and/or liquid between the vacuum source and thevacuum sealing apparatus 330. Preferably, thefilter 368 is removable so as to permit cleaning and/or replacement. Although the illustratedfilter 368 is disposed within theconnector 338, it is to be understood that thefilter 368 can be disposed in any location within thevacuum sealing apparatus 330 that allows for the blocking of particles or liquids. In yet other arrangements, thefilter 368 can be located within thevacuum source port 390. - In one arrangement, the method of using the
vacuum sealing apparatus 330 is similar to the above-disclosed method of using thevacuum sealing apparatus 30. First, the user attaches thevacuum sealing apparatus 330 to thevacuum source port 390. When theinlet portion 332 is rotated into a substantially vertical position (as shown inFIG. 14 ), the in-house vacuum system begins drawing air through theinlet portion 332. The user then uses thevacuum sealing apparatus 330 to remove air from a container. To deactivate the vacuum source, theinlet portion 332 is rotated to a substantially horizontal orientation. - In another arrangements, attaching the
vacuum sealing apparatus 330 to thevacuum source port 390 causes the vacuum source to begin operating, or the user can manually control the operation of the vacuum source. In yet another configuration, thevacuum sealing apparatus 330 can include a stop-cock valve, or the like, within theintermediate portion 334 that regulates the flow of air through thevacuum sealing apparatus 330. In such a configuration, when the vacuum source is turned on, rotating theinlet portion 332 downward opens the valve such that air is drawn in through theinlet portion 332, and rotating theinlet portion 332 upward closes the valve to decrease and/or stop air flow through thevacuum sealing apparatus 330. - Although the present invention has been disclosed in the context of certain preferred embodiments, examples and variations, it will be understood by those skilled in the art that the present invention extends beyond the specifically disclosed embodiments to other alternative embodiments and/or uses of the invention and obvious modifications and equivalents thereof. In addition, while a number of variations of the invention have been shown and described in detail, other modifications, which are within the scope of this invention, will be readily apparent to those of skill in the art based upon this disclosure. It is also contemplated that various combinations or subcombinations of the specific features and aspects of any of the many embodiments may be made and still fall within the scope of the invention. It should be understood that various features and aspects of the disclosed embodiments can be combined with or substituted for one another in order to form varying modes of the disclosed invention. Moreover, some variations that have been described with respect to one embodiment and not another embodiment can be used with such other embodiments. Many variations have been described herein and cross-application is intended where physically possible. Thus, it is intended that the scope of the present invention herein disclosed should not be limited by the particular disclosed embodiments described above, but should be determined only by a fair reading of the claims that follow.
