  • Patent number: 8951469
    Abstract: A sterile enclosure contains a transfer module defining a window. A port covers the window to maintain the inside of the enclosure as a sealed and sterile environment. A sliding, heated cutting element mounted on the port serves to sterilize and sever a portion of a sterile transfer bag assembly attached to the port. Preferably, the excised portion of the sterile transfer bag assembly is affixed to the port when the port opens. The sliding cutting element remains extended and heated to prevent contamination when the port is open. Further, a heating element is mounted about the window in order to sterilize around the opening when the port is open.

    Abstract: A cargo sealing-package apparatus comprises a larger plastic film coated with a layer of adhesive and an appropriate-thick paper base board, both larger than a cargo, and cushion elements with elasticity are adapted to protrusions extending from the cargo. The cargo is first placed flat onto the base board and, together, moved to a conveying platform of a preparation area (a cargo-feeding zone) to be transported into a working area (a vacuum-molding zone) and lifted upwards via an ascending/descending machine into a vacuum-heating area, bringing up air to inflate the plastic film undergoing pre-heating operation. Then, the air is drawn out to thermo-seal the plastic film around the shape of the cargo and adhere it in vacuum-binding onto the surface of the base board. Finally, the cargo accurately bound in a vacuum space is moved to a cargo-outlet area, achieving the benefits of anti-shock, humid-proof, dustproof, and anti-oxidized functions thereby.

  • Publication number: 20040200193
    Abstract: This invention is a novel process for skin packaging, and is an addition to the usual vacuum packaging processes. Instead of the skin being pushed down on to the object being sealed, by atmospheric air pressure created by a partial vacuum under the skin, it is instead pushed down on the object being sealed by increased external pressure. Both use the same difference between the outer air pressure and the inner air pressure. This difference in how the pressure differences are obtained, however, changes many of the procedures, and some of the results. There are many new opportunities opened up by this new process that can only be determined by further studies and experimentation.

  • Patent number: 5454214
    Abstract: An automatic vacuum packaging apparatus which is defined by a closable frame having upper and lower sections, the lower section including a heatable platen configured with one of several patterns of transversing channels through which air can be evacuated through two separate conduits drawn into one vacuum chamber located beneath the lower platen. The upper section is closable over the lower section and has a separate variable heating element and separate peripheral attachment to the vacuum. Plastic sheets may be placed on the upper and lower frames, and an object placed between them. Then, through the electronically controlled interaction of the vacuum, heating elements, channels and closure of the frames the object may be vacuum sealed between the plastic sheets. The patterns of channels allow for the improved removal of air as the channels vary in length thus increasing the ability of the vacuum to efficiently remove over 97% of the air by concentrating the pull of the vacuum in smaller areas.

  • Patent number: 5445696
    Abstract: A packaging arrangement for items to be subsequently mounted, having a pair of plastic sheets with dimensions that are greater than the item. One sheet includes an adhesive layer that adheres to the front face of the item and also adheres to portions of the other sheet so that the item is captured in between. The sheet with the adhesive layer is preferably transparent. When mounting, the sheets are separated, a mounting adhesive is applied to the back face of the item, and thereafter both the adhesive layer and the back face are urged against the mounting surface. The sheet temporarily maintains the item mounted until the mounting adhesive hardens and the sheet is thereafter removed. The item can a single unit, or a plurality of loose units, or a plurality of units attached to a backing. If a single unit or a plurality of pre-connected units, the packaging arrangement need not attach to the entire item.

  • Patent number: 5165220
    Abstract: Apparatus for skin packaging articles on a backing card in which a heating unit for film is disposed behind a work table having a vacuum platen on which may be placed a backing card with an article to be packaged; and, upon activation, is moved vertically between a first position above the level of the table and a second position not higher than the table level. A film clamping frame holds a section of film closely above the heating unit when it is in its first position, and when the unit is moved to its second position, moves the heated clamped film section forward and downward onto a backing card where it is drawn down tightly against the article on the card upon creation of a vacuum. Upon completion of the packaging, the backing card is pulled forwardly off the table and its film is severed from the further film which is pulled with it, such further film then being clamped on the film clamping frame which is moved back up to its elevated position for repetition of the cycle.

  • Patent number: 5076436
    Abstract: In a vacuum skin package wrinkles and weak spots are avoided by providing a tray as the support or backing member rather than a flat sheet, the angle of the walls as they diverge outwardly being 91.degree. to 160.degree.. Especially useful is such a package when provided with a lid for stacking purposes.

  • Patent number: 5072574
    Abstract: A vacuum packaging apparatus for packaging a product between a plastic film and a backing card comprises a base having a stationary heating hood. A reciprocal table is mounted on the base beneath the hood. Two packaging wells are mounted side by side on the table, each well being dimensioned for holding a backing board on which the product is placed for packaging. The reciprocal table moves laterally on the base so that when one packaging well is in a packaging position under the hood, the other packaging well is not and extends out from beneath the hood. A sealing frame is mounted on the base beneath the hood for holding a sheet of wrapping material and moves vertically between a raised position and a lowered position. In the raised position, the sealing frame is adjacent the heating hood to heat the sheet. In the lowered position the sealing frame is adjacent the packaging well which is in packaging position to place the heated sheet over the board.

  • Patent number: 5069018
    Abstract: A vacuum packaging apparatus for packaging a product between a plastic film and a backing board includes a base which has a stationary heating hood. A packaging table is mounted on the base and offset from the hood to extend laterally and outwardly from the hood. A sealing frame is mounted on the base for holding a sheet of wrapping material. First and second elongated arms are pivotally attached to both the base and the frame to connect the frame to the base. The arms may be pivoted to move the frame from a sealing position, wherein the frame is positioned adjacent the packaging table, to a heating position, wherein the frame is positioned adjacent the heating hood to heat the sheet. A vacuum motor is mounted in the base beneath under the packaging table. When the sealing frame is lowered to the sealing position to place the heated sheet over the board, a vacuum is drawn against the backing board to seal the heated sheet over the product onto the backing board.

  • Patent number: 5025611
    Abstract: An apparatus for packing perishable goods in which perishable foods are placed in a pre-formed base. A first flexible gas permeable plastic web is then placed over said goods, and a reduced pressure is established below the first web relative to that above the first web for effecting at least partial skin packing of the first web over the goods. A second plastic web is then placed over the first web, the goods and the base. A second web is then sealed to the base so as to provide a space between the first web and the second web. A gas is provided in the space between which can permeate through the first web toward the base to enhance preservation of the goods. The second web comprises a lid serving to retain the gas in the space.
