Abstract: The present invention relates to a method of attaching an active film (5) onto a flexible package comprising the steps of heating a foil (2); applying an active film (5) to the foil (2); and applying sufficient pressure to the active film (5) and foil (2) combination and sufficient heat to the foil (2) so that active film (5) adheres to the foil (2). In one example, the active film (5) comprises two components and wherein the two components are an active agent and a polymer. In another example, the active agent is an absorbing material.

Abstract: A hinged container is disclosed, including a base, a lid, and a hinge joining the base and lid, allowing the lid to pivot open or closed relative to the base. One of the base and the lid has a circular, outwardly tapered outer seal member disposed at least partially within its outer perimeter. The other of the base and the lid has a circular, inwardly-tapered inner seal member disposed at least partially within its outer perimeter. The inner and outer seal members are positioned to engage concentrically to wedge the inwardly and outwardly tapered surfaces together and form a seal when the base and the lid are closed, and to disengage concentrically to part the inwardly and outwardly tapered surfaces when the base and the lid are opened.
Abstract: In embodiment, the present invention relates to a cap and container assembly comprising at least one selective gas permeable membrane, wherein the assembly is manufactured so that the membrane is an integral part of the assembly and wherein the membrane is composed of a material for controlling conditions of gas concentration in an internal portion of the assembly when the cap is closed. In another embodiment, the present invention relates to a method of forming a cap and container assembly comprising at least one selective gas permeable membrane that is integral with the assembly comprising: cutting the membrane to a pre-selected form, wherein the membrane is composed of a material for controlling conditions of gas concentration in an internal portion of the assembly when the cap is closed; placing the membrane into a mold by robotic means; and overmolding the assembly about the membrane to form an assembly wherein the membrane is an integral part of the assembly.
Abstract: A substantially moisture tight container and lid assembly for storing and packaging moisture-sensitive items comprising an assembly with a container and a lid, the lid is attached by a hinge to an upper housing portion of the container, the container has a container base, and a sidewall depending upwardly from the base, a top container surface extends inward from the sidewalls, the top container surface is provided with an opening that permits access to the interior of the container, the lid portion has a lid base with an outer periphery that extends over at least a portion of the container portion, the lid base is provided with a skirt that depends downwardly from the base portion, the skirt is configured at a location on the base portion that allows the skirt to enter into a sealing relationship with the container portion, the lid includes a member that depends downwardly from the lid, the member is configured to abut at least a portion of the interior side of the container when the lid is in the closed pos
Abstract: A multi-compartment housing with a plurality of cavities forms the main part of the housing. The multi-compartment housing has a side portion that has a smooth, continuous surface and a plurality of individual cavities that are perpendicular to a central axis of the multi-compartment housing. The individual cavities have a plurality of plugs capable of being placed in communication with a corresponding individual cavity. The multi-compartment housing also has a sealing bottom that is capable of being secured onto the multi-compartment housing after the plug array has been placed in position and separated from adjacent plugs from the array so as to close off the of the multi-compartment housing and to isolate each plug from adjacent cavities.

Abstract: The present invention includes processes and resulting structures for producing a modified polymer having interconnecting channels. The interconnecting channels act as controlled transmission passages through the polymer. A hydrophilic agent is blended into the polymer so that it is distributed within the polymer. In one embodiment, a releasing material is blended into the polymer so that the releasing material is distributed within the product. The product is solidified so that the hydrophilic agent forms passages in the product through which a desired composition is communicable to the releasing material that is entrained within the product. The solidified product may be used to form a desired shaped article such as plug type inserts and liners for closed containers, or it may be formed into a film, sheet, bead or pellet.
