FIGS. 1-7 will be used to describe the vacuum packaging operation in general, with an emphasis setting the stage for the teaching of the present invention. - Prior Art
FIG. 1 illustrates a multi-layer film 10 that is one common structural configuration for prior art vacuum packaging bag material. The film 10 includes a permanentsealing resin layer 12, abond layer 14, a gasimpermeable layer 16, a bond layer 18, and astructural layer 20.Bond layers 14 and 18 act to laminate opposing layers. Thestructural layer 20 provides strength so that the film 10 is useful as a vacuum packaging bag material. The gasimpermeable layer 16 tends to inhibit gas flow across the film 10. The permanentsealing resin layer 12 is used to form permanent seals between two sheets of the film 10 as formed in a bag, pouch or storage receptacle. As will be appreciated, preformed vacuum packaging bags and bag roll material are the common commercial end products made from vacuum packaging films such as film 10. - Prior Art
FIG. 2 illustrates avacuum packaging bag 20 ready for use by a consumer. Thevacuum packaging bag 20 is made of twosheets FIG. 1 . Thebag 20 has been heat-sealed on three sides formingpermanent seals bag 20 is formed with an opening 32 wherein the user can insert product. The opening 32 is later used to evacuate thebag 20. - Prior Art
FIG. 3 illustrates thevacuum packaging bag 20 after a consumer has inserted aproduct 40 within thebag 20. As will be appreciated, bags such asbag 20 can be purchased by the consumer in preformed manufacture, or may be formed to a desired size by the consumer using the vacuum packaging appliance and a roll of bag material. - A prior art
vacuum packaging appliance 100 is described now with reference toFIGS. 4-5 . Thevacuum packaging appliance 100 includes aheat seal mechanism 102, adrip tray 104 which is part of a vacuum circuit, aroll 108 of bag material, acontrol panel 110, and acutting tool 112. Theheat seal mechanism 102 is operable to heat-seal thebag 20. - With further reference to
FIG. 4 , thedrip tray 104 serves to capture contaminants during evacuation of thebag 20. When theopen end 32 of thebag 20 is coupled to the vacuum circuit and the lid of theappliance 100 closed as shown inFIG. 5 , the vacuum circuit is closed and thebag 20 may be evacuated. Note that during operation the user must steady thebag 20 within thedrip tray 104, being especially careful to ensure theopen end 32 maintains coupling with the vacuum circuit as the lid is closed. Once, but not until, the lid is closed, thebag 20 is held in place. As will be appreciated, over multiple cycles of use or in packaging products with substantial liquids and/or contaminants, thedrip tray 104 can become unhygienically dirty, and thetray 104 itself may become full preventing effective evacuation and possibly damaging the vacuum system of theappliance 100. - The
roll 108 has preformedheat seals roll 108 may be unfurled by the consumer to form a bag of any desired size. Thecutting tool 112 is operable to cut the unfurled bag material. When creating bags of desired size, the consumer typically adds a third seal before placing theproduct 40 in thebag 20. - Prior Art
FIG. 6 is a flow chart illustrating amethod 50 for vacuum sealing, storing and then accessing a product in a vacuum packaging bag. In aninitial step 52, the consumer prepares avacuum packaging bag 20 for use. This may involve the consumer using an appliance to form thebag 20 from bag roll material, i.e., cutting the desired amount of bag material and forming the third seal and leaving an open end. Alternatively, the consumer may utilize a preformedbag 20. - In a
next step 54, aproduct 40 is placed within thebag 20; as illustrated inFIG. 4 . Theproduct 40 may be food, collectible items, or anything the consumer desires to store in an evacuated bag. In a step 56, the consumer couples thebag 20 holdingproduct 40 to the vacuum circuit of theappliance 100. This is illustrated inFIGS. 4-5 . In coupling thebag 20 to the vacuum circuit, the consumer must be careful so that no product spills or gets in the way of the coupling, while making sure thebag 20 stays in it proper place. In a step 58, the consumer shuts the lid so that thedrip tray 104 captures the bag, and then activates theappliance 100 to evacuate thebag 20. The vacuum level may be predefined and reached automatically, or may be controlled by the consumer. In any event, once the desired vacuum level is reached in thebag 20, the consumer activates theheat sealing mechanism 102 that then seals thebag 20. As shown inFIG. 7 , thebag 20 now has afourth seal 34. - In a step 62, the consumer stores the
product 40 in the vacuum-sealedbag 20. For example, when the product is food, the consumer may store thebag 20 in a fridge or freezer. The user accesses product in thebag 20 by using a tool such as a scissors to cut through thebag 20. Accordingly, in astep 64, the consumer uses a scissors or other tool to open the bag to access theproduct 40. Then in a step 66, the consumer may reuse any remaining portion of the bag. - What is needed is a mechanism to assist the user in holding the bag in place during operation of the vacuum packaging appliance, particularly during the operation of inserting the bag and later closing the lid. This mechanism should be particularly suited for use in the evacuation process, but may also be helpful in forming seals on bag roll material when preparing bags for use. Further, a mechanism is needed to overcome problems arising when the drip tray becomes filled with contaminants.
- The present invention teaches a variety of bag clamps, mechanisms and techniques for securing a bag within a vacuum packaging appliance during operation of the vacuum packaging appliance. The bag clamp has an open position and a closed position. The open position is suitable for receiving an open end of the vacuum bag. The closed position is suitable for capturing and holding the open end of the vacuum bag during operation of the vacuum packaging appliance. A vacuum packaging appliance according to the present invention has at least one bag clamp, typically disposed within and fixedly attached to a drip tray.
