The present application claims priority to U.S. provisional application No. 60/492,726, filed Jul. 29, 2003 by Brakes and entitled VACUUM PACKAGING APPLIANCES INCLUDING SUPPORT ASSEMBLIES FOR CARRYING BAG MATERIAL, the contents of which are incorporated herein by reference.
TECHNICAL FIELDThe present invention generally relates to vacuum packaging. More particularly, the invention is directed to vacuum packaging appliances including support assemblies for carrying bag material.
BACKGROUNDVacuum packaging involves removing air or other gases from a storage container and then sealing the container to prevent the contents from being exposed to the air. Vacuum packaging is particularly useful in protecting food and other perishables against oxidation. Oxygen is a main cause of food spoilage and contributes to the growth of bacteria, mold, and yeast. Accordingly, vacuum packaged food often lasts three to five times longer than food stored in ordinary containers. Moreover, vacuum packaging is useful for storing clothes, photographs, silver, and other items to prevent discoloration, corrosion, rust, and tarnishing. Furthermore, vacuum packaging produces tight, strong, and compact packages, reducing the bulk of articles and allowing for more space to store other supplies.
Conventional vacuum packaging bags include two panels attached together with an open end. Typically, the panels each include two or more layers. The inner layer can be a heat sealable material, and the outer layer can be a gas impermeable material to provide a barrier against the influx of air. The plasticity temperature of the inner layer is lower than the outer layer. Accordingly, the bag can be heated to thermally bond the inner layer of each panel together to seal the bag without melting or puncturing the outer layer during the heat sealing cycle.
A conventional vacuum packaging process includes depositing the object 12 in the bag 10 and positioning an open end 11 of the bag 10 in the lower trough 26 of the vacuum packaging appliance 1. Next, the lid 40 pivots downward to form the vacuum chamber with the open end 11 of the bag 10 disposed within the vacuum chamber. The vacuum pump then removes gas from the vacuum chamber and the interior of the bag 10, which is in fluid communication with the vacuum chamber. After the gas has been removed from the interior of the bag 10, the heating element 28 heats a strip of the bag 10 proximate to the open end 11 to melt the inner layer of each panel and thermally seal the bag 10.
Vacuum packaging bags are typically formed from a roll of bag material that is cut into sections. The roll generally includes a strip of bag material having two panels sealed together along each lengthwise side. It is desirable to store the roll of bag material so that the material can be dispensed easily and conveniently for use with the vacuum packaging appliance. In some appliances, the base includes an opening adjacent to the lower trough to receive the roll of bag material. These vacuum packaging appliances are typically larger than other vacuum packaging appliances because the bag material is stored internally within the appliance. Bigger vacuum packaging appliances have larger footprints and consequently use more space on a countertop or other surface. Accordingly, there is a need to store the bag material at a convenient location without increasing the size of the vacuum packaging appliance.

For example, in operation, the open end of the bag is positioned in the first chamber portion 126, and then the lid 140 is pivoted to the closed position. Conventional vacuum packaging bags, such as those disclosed in U.S. Pat. No. Re. 34,929, which is hereby incorporated by reference in its entirety, are configured so that the interior of the bag is in fluid communication with the vacuum chamber when the lid 140 is in the closed position. Accordingly, the vacuum pump can remove gas from the vacuum chamber and the interior of the bag.
In the illustrated embodiment, the vacuum packaging appliance 100 further includes a heating element 128 and a member 150 for pressing the bag against the heating element 128. The heating element 128 can be carried by the base 120, and the member 150 can be carried by and project from the lid 140. The heating element 128 is configured to thermally seal the bag after the gas has been substantially evacuated from the interior of the bag. Conventional vacuum packaging bags include panels that have a gas impermeable layer and a heat sealable layer inside the gas impermeable layer. The heating element 128 heats the bag sufficiently to bond the heat sealable layer of the panels together. The member 150 is configured to press the bag against the heating element 128 to ensure a seal is formed across the bag.
In the illustrated embodiment, the housing 130 includes a slot 131 to limit the range of motion of the support assembly 160. More specifically, the slot 131 includes a first end 132 and a second end 133, and the support assembly 160 includes a pin 172 slideably received in the slot 131. In the deployed position, the pin 172 contacts the first end 132 of the slot 131 to limit the movement of the support member 162. Similarly, in the stowed position, the pin 172 can contact the second end 133 of the slot 131 to limit the movement of the support member 162.
In the deployed position, the upper surface 163 of the support member 162 and the rear surface 136 of the housing 130 support the bag material 110 in the illustrated embodiment. The bag material 110 can be a generally tubular receptacle that is arranged in a roll. The tubular receptacle can include two panels that are sealed together along each lengthwise side. The bag material 110 can be cut into sections, and the two open ends of each section can be sealed to form a sealed bag. In other embodiments, the support assembly 160 can carry bag material that is arranged differently.
The support member 162 is pivoted in a direction S1 to move the support assembly 160 from the deployed position to the stowed position.

For example, the support assembly 160 can be pivotably attached to the lid, and/or the support assembly 160 can include an elongated support member sized and configured to be received in a hole at the center of a roll of bag material. In additional embodiments, the support assembly 160 can include a cutting device such as the device described below with reference to
One feature of the illustrated vacuum packaging appliance 100 is that a user can selectively store bag material 110 on the support assembly 160. An advantage of this feature is that the support assembly 160 gives the user the flexibility to selectively store the bag material 110 at a convenient location on the vacuum packaging appliance 100 without permanently increasing the footprint of the appliance 100. For example, the bag material 110 may be temporarily placed on the support assembly 160 while the user vacuum packages several items. Thereafter, the user may return the bag material 110 to a drawer or store the material 110 at another location and reduce the footprint of the vacuum packaging appliance 100 by stowing the support assembly 160. Another advantage of the illustrated appliance 100 is that the support assembly 160 conveniently dispenses the bag material 110. For example, if the bag material is arranged in a roll, the roll can be easily rotated on the support assembly 160.
In the deployed position, the first and second support members 262 and 266 define an opening 265 sized to receive bag material. To move the support assembly 260 from the deployed position to the stowed position, the second support member 266 is pivoted in a direction S2 toward the first support member 262 so that a first surface 267 of the second support member 266 contacts a surface 236 of the first support member 262. Next, the first and second support members 262 and 266 are pivoted in a direction S3 so that a second surface 268 of the second support member 266 contacts the rear surface 236 of the housing 230. In other embodiments, the support assembly 260 can have other configurations.
In the stowed position, the first support member 362 is received within the housing 330 and the second support member 366 is positioned against the rear surface 336. To move from the stowed position to the deployed position, the support assembly 360 moves in a direction D1. In the deployed position, the first and second support members 362 and 366 define an opening 365 sized to receive bag material. In the illustrated embodiment, the first support member 362 includes an end portion 364 that remains within the housing 330 and interacts with the base 320 to support the first and second support members 362 and 366 and the bag material when the support assembly 360 is in the deployed position. The first support member 362 and/or the housing 330 can include a stop mechanism (not shown) or a detent to prevent a user from moving the end portion 364 out of the housing 330. In other embodiments, the first support member 362 can be removed from the housing 330.
In the illustrated embodiment, the support assembly 360 further includes a cutting device 380 (shown schematically) coupled to the second support member 366. The cutting device 380 can be a knife or other suitable device to cut the bag material to form bags. The cutting device 380 can be fixed to the second support member 366 or slideable along the length of the member 366. In other embodiments, the vacuum packaging appliance 300 may not include the cutting device 380, or alternatively, the cutting device 380 can be coupled to the base 320 or the lid.
In the stowed position, the support assembly 460 is received within the housing 430. More specifically, the first support member 462 is juxtaposed to the second support member 466 in the housing 430. To move from the stowed position to the deployed position, the support assembly 460 slides in a direction D2 to move the second support member 466 and a portion of the first support member 462 out of the housing 430. Next, the second support member 466 pivots in a direction S4. In the deployed position, the first and second support members 462 and 466 form an opening 465 to receive bag material. In the illustrated embodiment, the first support member 462 has a first width W1 and the second support member 466 has a second width W2 less than the first width W1 so that an end portion 464 of the first support member 462 can remain within the housing 430 to support the first and second support members 462 and 466 and the bag material when the support assembly 460 is in the deployed position.
