  • Publication number: 20120067896
    Abstract: A resealable and disposable package assembly is described. The assembly includes a container and a multilayer cover laminate that are bonded to one another to initially seal the contents of the package. The package can then be easily opened by at least partially separating the cover laminate along a predesignated interface. The package can be reliably and effectively sealed by recontacting the previously separated cover portions to one another.

  • Patent number: 8083089
    Abstract: A tamper-evident rigid plastic food container system wherein the outer periphery of the mating surfaces of the lid and tray are permanently bonded together after the food product has been placed in the tray, a set of perforated rows at an inner periphery, the interconnect of which needs to be torn into order to open the lid. Intentional, inadvertent or malicious ingress into the container can only be made by tearing at the perforations thereby evidencing the potential tampering and contamination of the packaging contents. The lid and tray edges may further include mechanical interference fits, including snap-fit grips that may be of the releasably lockable kind to permit sealing, release and re-sealing multiple times without deterioration in reliability, and which can further prevent or minimize leakage of liquid food product.

  • Patent number: 8070008
    Abstract: A plug to hermetically seal an aperture in a sheetmetal, or in the floor of a vehicle, comprising, a cap covering the aperture and comprising an external, circumferential flange resting on one side of the sheetmetal or of the floor and fitted with a first circumferential seal, an affixation portion entering said aperture and, a second circumferential seal configured at the cap or at the affixation portion and being a distance from the first seal and resting against the sheetmetal or the said floor, a cavity being subtended by the sheetmetal or said floor, the two seals and at least one wall of the plug, where said plug, includes a pressure-compensating chamber, which communicates with the cavity and, which compensates a change in pressure, caused by a change in temperature, inside the cavity, by changing the volume of the pressure-compensating chamber.

  • Patent number: 7997437
    Abstract: A plug (10) for sealing holes in a vehicle body comprises a central closure section (12) and engaging section (14) arranged on the rim and provided for receiving portions of the vehicle body. The closure section (12) and the engaging section (14) are made of a plastics material and the plastics material of the engaging section (14) is softer than the plastics material of the closure section (12). The plastics material of the engaging section (14) can be softened by heating such that a tight connection is produced between the engaging section (14) and the portions of the vehicle body that are received by it.

  • Publication number: 20110095030
    Abstract: A container assembly includes a container body having a side wall encircling an axis, and a metal end for attachment to an upper edge of the side wall via heat-sealing. The outer peripheral region is shaped prior to application to the container body such that an annular channel is defined between an inner chuck wall and an outer chuck wall of the metal end. The metal end is pushed straight onto the side wall such that the upper edge of the side wall is received into the channel. The surfaces of the side wall and the opposing surfaces of the chuck walls have heat-sealable material thereon. The metal end is heated to melt and fuse the heat-sealable layers, thereby sealing the metal end onto the side wall. The metal end is shaped such that the free edge of the outer chuck wall is not exposed.

  • Patent number: 7891516
    Abstract: A container is thermoformed from a multilayer sheet, which includes a container body and a flange extending outward from a circumference of an opening of the container body. An end of the first layer extends over an edge of a peeled surface toward a bottom side on an outer end surface of the flange. When a lid is heat-sealed to the flange of the container, even if a seal resin is melted and flowed toward the end surface of the flange, since the edge of the peeled surface is covered with the end of the first layer, the seal resin will not adhere to the edge of the peeled surface.
