Description
- The present invention relates to the field of storage technology. More particularly, the present invention relates to accessories for a vacuum appliance for consumer and industrial applications.
- Consumer products involving vacuuming and sealing plastic bags have grown in popularity over the years. The basic model available includes a seal wire that seals the length of the bag and a vacuum pump which pumps air out of the bag prior to sealing. This model works well enough to have sold and inspired imitation.
- Unfortunately, the model described provides vacuum capability only for plastic bags. Much food and similar material is better stored in jars. Jars with a lid having an aperture or one-way vent of some form may be vacuumed through use of a hose, but cannot be inserted into a slit-shaped opening for this purpose. Moreover, it may be useful to adapt basic jars for use with vacuum applications.
- Similarly, some foods may be easily stored in plastic bags with little fuss. However, other foods may be placed on a tray, with the food and the tray stored in a vacuum-sealed bag together. Moreover, storing food with a tray may allow for easier reheating of frozen food. Accordingly, adapting a tray for use with vacuum applications may be useful. In general, it may be useful to integrate the food storage methodology with the container in which the food is stored, potentially increasing efficiency and effectiveness of the method and the packaging.

- Turning to the Figures,
FIG. 1 illustrates an embodiment in perspective view of a jar, which may be useful with a vacuum appliance.Jar 100 has anouter layer 110 and aninner layer 120, between which is a channel orchamber 130.Inner layer 120 may be formed as a single piece along withinner bottom 125, or may be joined toinner bottom 125.Inner layer 120 andouter layer 110 may be joined together at some point, such as at the top ofjar 100 as illustrated.Surface 150 ofinner layer 120 andsurface 140 ofouter layer 110 collectively define the bounds ofchamber 130.Valve 160 provides access throughouter layer 110 tochamber 130. Thus,chamber 130 may be evacuated throughvalve 160 in a selective manner, allowing for potentially better insulation characteristics forjar 100. -
FIG. 2 illustrates an embodiment from a top view of a jar which may be useful with a vacuum appliance. As illustrated,valve 160 is located onouter layer 110, butvalve 160 may be located in other positions, such as at a point whereouter layer 110 andinner layer 120 are joined, for example.FIG. 3 illustrates an alternate embodiment from a side cutaway view of a jar which may be useful with a vacuum appliance. Making a cut alongline 3 ofFIG. 2 exposes the view ofFIG. 3 .Chamber 130 is shown to extend throughoutjar 100, andvalve 160 is better shown to communicate withchamber 130. Note thatvalve 160 may also be suitable to use in fillingchamber 130, with a hot or cold liquid for example. Moreover, note thatvalve 160 is preferably designed to receive a hose or tube on its external end. Also, note thatapparatus 100 has been described and illustrated as a jar, while it may easily be implemented as a cup instead, typically with angled sidewalls rather then vertical sidewalls. - While a jar has potential applications for storage of food where a bag cannot be used, a tray may be used in conjunction with a bag or to complement a bag.
FIG. 4 illustrates an embodiment in a perspective view of a tray which may be useful with a vacuum appliance.Tray 400 includesinner bottom 410,inner sidewalls 415,outer layer 420,chamber 430, andvalve 460.Valve 460 communicates selectively betweenchamber 430 and an external atmosphere or pump.Chamber 430 is defined by theinner surface 425 ofinner bottom 410 and an inner surface ofouter layer 420, such that it may provide for either a vacuum or filled cavity withintray 400.Valve 460 may be used to either evacuate or fillchamber 430.FIG. 5 illustrates an embodiment from a top view of a tray which may be useful with a vacuum appliance.FIG. 6 illustrates an embodiment from a side cutaway view of a tray which may be useful with a vacuum appliance. The cut alongline 6 ofFIG. 5 exposes the view ofFIG. 6 . -
FIG. 7 illustrates an embodiment of a tray as it may be used with a vacuum appliance. As illustrated inFIG. 7 , a piece of food (illustrated as a chicken leg) is placed on theinner bottom 410 oftray 400 and abag 470 is placed over thetray 400 and food contained therein. In one embodiment, thetray 400 may be evacuated throughvalve 460 to provide insulation between thetray 400 and any external surface underneath. Thebag 470 may be evacuated and sealed, thus providing for a sealed, vacuum-packed, food storage container. The locations and shapes of the various components may be varied, such that a round tray or a tray without sidewalls may be used, and such thatvalve 460 may be located at any convenient location. - Moreover, the food may be heated on the
tray 400, such as through use of a microwave oven. Tests have shown that the use of an evacuated tray such astray 400 enhances heating of the food placed thereon, allowing for quicker or more efficient heating. This is particularly true when the tray sits on legs as the microwaves are believed to become more focused on the tray and thus the product. Moreover, using the tray in the bag potentially provides a more convenient and portable package for food, as a plate or similar item is not necessary when the food is consumed. - As with the tray of
FIGS. 4-7 , methods of using the tray ofFIGS. 1-3 may be useful.FIG. 8 illustrates an embodiment of a process of using a jar with a vacuum appliance. Atblock 810, food is placed in the jar. Atblock 820, the chamber within the jar (such aschamber 130 for example) is evacuated (such as throughvalve 160 for example). Atblock 830, the lid of the jar is sealed (such aslid 77 for example). Atblock 840, the inside of the jar is evacuated (such as throughlid 77 for example). Atblock 850, the jar is frozen, for long term storage. Atblock 860, the jar is unsealed, allowing access to the food inside and filling the vacuum therein. Atblock 870, the food is used. Various blocks of this process may be rearranged or left out, such that the chamber within the jar may be evacuated before food is added to the jar, or may not be evacuated at all for example. Similarly, the jar need not be frozen for example. - As with the jar, the tray of
FIGS. 4-7 may be used in different ways.FIG. 9 illustrates an embodiment of a process of using a jar with a vacuum appliance. Atblock 910, food is placed on a tray, such astray 400 for example. Atblock 920, the chamber within the tray is evacuated, such aschamber 430 evacuated throughvalve 460 for example. Atblock 930, the tray is placed in a bag, such asbag 970 for example. Atblock 940, the bag is evacuated. Atblock 950, the evacuated bag is sealed. Atblock 960, the sealed and evacuated bag is frozen for long-term storage. Atblock 970, the bag is unsealed, allowing access to its contents. Atblock 980, the food is microwaved on the tray. Atblock 990, the food is then used. - The method of
FIG. 9 allows for great flexibility. For example, the blocks ofFIG. 9 may be reordered in appropriate ways, such as by evacuating the chamber of the tray atblock 920 before placing food on the tray atblock 910. Moreover, the tray need never go into the bag, thus leaving blocks 930-970 out of the method in some embodiments. Alternatively, the bag need not be frozen (omitting block 960) or the food need not be microwaved (omitting block 980). Moreover, the chamber of the tray need not be evacuated, as atblock 920. - Preferably, the jar of
FIGS. 1-3 and the tray ofFIGS. 4-7 are used with a vacuum appliance having a hose suitable for use with the valves depicted.FIG. 10 illustrates an embodiment of a vacuum appliance which may include a vacuum hose and may be used with a jar or tray such as those described above. In particular,FIG. 9 shows a perspective view of an embodiment of avacuum appliance 20.Buttons appliance 20 to activate a vacuum pump and a heat sealing wire.Indicators vacuum hose 85 may be used with opening orvalve 86 to couple the vacuum pump ofappliance 20 to a valve on another device, such as a jar or tray, or a lid for a jar. -
FIGS. 10-17 illustrate alid attachment 77 for acontainer 78 adapted for connection to a vacuum pump ofapparatus 20 for the purpose of selectively evacuating the container. The lid attachment includes anannular lid adapter 79 and an annularelastomeric seal 80 secured thereunder to form a static seal at anupper flange 81 ofcontainer 78. The lid attachment further comprises anannular connector 82 having an annularelastomeric seal 83 secured thereunder to engage a radially outer surface of anannular ridge 84 formed onlid adapter 79. - A flexible
plastic tube 85 is attached betweenconnector 82 and an opening orconnector 86, formed through the top panel of appliance 20 (FIG. 10 ).Connector 86 may be used to provide a connection or coupling between tube orhose 85 and the vacuum pump ofappliance 20. - Referring to
FIGS. 11-17 , athumbnut 88 is threaded onto aneck 89, formed centrally onlid adapter 79. As illustrated, an indicia marking in the form of anarrow 90 is formed on the thumb-nut to visually indicate one of three operative positions of the thumb-nut, i.e., “vacuum”, “closed”, or “open” as marked onlid adapter 79. When the thumbnut is rotated to its “vacuum” position illustrated inFIGS. 12 and 13 , a user is enabled to useapparatus 20 andpress button 66 to draw a vacuum incontainer 78. - In particular, a
plastic disc 91 is “loosely” mounted withinthumbnut 88 and forms a valve element that openly communicates the vacuum drawn in tube 85 (FIGS. 10 and 11 ) with the container. The vacuum is drawn across atransverse slot 92 formed in the upper surface of the disc and through a centrally disposedpassage 93, formed throughneck 89. The applied vacuum will induce a lifting ofdisc 91, which overliespassage 93, to aid in evacuation. - A plurality of radially and circumferentially spaced hook-like fingers or
retention members 94 are formed integrally with the disc in upstanding relationship thereon to extend through a mounting hole and overlie aflange 95 defined on the thumb-nut for retention purposes. The retention members are sufficiently flexible and resilient to permit a snapping-out of the members from their mounting hole, formed centrally through the thumbnut. InFIG. 13 a flexible detent 96 is formed integrally on a sidewall or skirt of the thumbnut to extend radially inwardly to releasably engage within agroove 97, formed on the outer side ofneck 89. - This detent arrangement will releasably retain the thumb nut is in its illustrated “vacuum” position in
FIG. 12 . A similar detent arrangement is also provided for releasably holding the thumb screw in each of its “closed” (FIGS. 14 and 15 ) and “open” (FIGS. 16 and 17 ) positions. Otherwise stated, three circumferentially spaced (120° apart)detents 96 and their associatedgrooves 97 are formed on the thumbscrew and neck for this purpose. During evacuation ofcontainer 78 the large chamber and reservoir defined betweenlid adapter 79 andconnector 82 will collect and prevent liquids and powders, drawn from the container, from enteringtube 85. - After the container has been evacuated,
connector 82 is removed andthumb nut 88 is turned-down to its “closed” position illustrated in FIGS. 14 and 15 to compress the flat underside ofdisc 91 against an O-ring seal 98, mounted onneck 89 to surroundpassage 93. When the connector is removed, the vacuum in the container will pulldisc 91 againstseal 98 to retain the vacuum until the thumbnut is turned-down. Anannular bead 99 is formed beneathflange 95 of the thumbnut to engage the upper side ofdisc 91 to compress it against the seal. Diametrically extending andnarrow slot 92 will not interfere with this closing function. - When the user chooses to release the vacuum in the container, thumbnut 88 is released to its
FIGS. 16 and 17 position wherebyflange 95 will engage beneath the hook ends ofretention members 94 to raisedisc 91 fromseal 98. Air is thus permitted to ingress into the container viaslot 92 andpassage 93. - While a detailed and complex valve has been described with respect to
FIGS. 10-17 , a simpler valve may be used asvalve hose 85 for example, to allow for evacuation of the chambers formed injar 100 ortray 400 for example. - With respect to
FIGS. 18-21 , an embodiment of the present invention which provides simultaneous evacuation of the chamber and the inside of the container will now be described.FIG. 18 illustrates acontainer 200 having a sealedchamber 202 and a one-way valve 204. The one-way valve 204 vents thechamber 202 to the outside of thecontainer 200. The one-way valve 204 is by some mechanism coupled to both the inside of thechamber 202 and the inside of thecontainer 200 such that evacuating through the one-way valve 204 evacuates both the inside of thecontainer 200 and thechamber 202. -
FIG. 19 illustrates acontainer 200′ having avalve 204′. Thevalve 204′ travels through thechamber 202 into the inside of thecontainer 200. Thevalve 204′ has intakes both within thechamber 202 and inside thecontainer 200. -
FIG. 20 illustrates acontainer 200″ having twovalves 204′ and 206. Thevalve 204′ is one-way, having an intake within thechamber 202, and a vent outside thecontainer 200. Thevalve 206 is one-way, having an intake inside thecontainer 200 and a vent inside thechamber 202. - Both embodiments of
FIGS. 19-20 enable simultaneous evacuation of the chamber and the container. - From the foregoing, it will be appreciated that specific embodiments of the invention have been described herein for purposes of illustration, but that various modifications may be made without deviating from the spirit and scope of the invention. In some instances, reference has been made to characteristics likely to be present in various or some embodiments, but these characteristics are also not necessarily limiting on the spirit and scope of the invention.
