Abstract: A treatment for peeled or sliced produce, particularly sliced apples, comprises the steps of placing the sliced produce in a preferred solution for approximately 20 seconds and storing the treated produce at approximately 40 degrees F. One chemical composition for the treatment of peeled or sliced produce, particularly sliced apples, is a treatment solution composed of water plus the following chemicals by weight %: Lactic Acid 0.51% Ca-Lactate 0.34% CaCl2 1.13% CaCO3 1.07% Ascorbic Acid 3.95% Total 7.

Abstract: A container closure (10) including a peripheral ring member (20) for securing the closure to a container or can body (not shown), and including a molded, polymer ring member (14) and central end panel (12) that are removable from the peripheral ring member for opening the end of the container or can body. The polymer ring member is adhesively bonded to a vertical wall portion (24) of the peripheral ring member and includes an integral lip portion (28) for covering a raw terminal edge of wall portion 24. The adhesive is formulated so that the bond fails cohesively during removal of the polymer ring member. The polymer ring member contains an oxygen-scavenging additive for reducing oxygen inside the container and reducing oxygen ingress into the closed container.

Abstract: An oxygen absorber includes an iron powder, and a first layer coated on a surface of the iron powder and formed of iron chloride through a chemical reaction. Further, the oxygen absorber includes a matrix material filled with the iron powder covered with the first layer of iron chloride. It is possible to coat the first layer on the surface of the iron powder with a second layer to obtain more uniform coating.

Abstract: A CO2 releasing composition that can be incorporated into the packaging for carbonated beverages having a co-continuous interconnecting channel morphology comprising at least three components, (a) wherein component A is selected from the group of polymers that are semicrystalline polymers and amorphous polymers, wherein the amorphous polymers have a shear modulus greater than about 8 MPa; (b) wherein component B is a polymer; (c) wherein components A and B are immiscible within each other and, if components A and B react after mixing, components A and B are immiscible prior to reaction; (d) wherein component C is a particle and a composition that has an ability to release CO2.

Abstract: Closing of a metal container and the like using a special end closure. The open end portion of a container is outwardly folded to define a supporting ledge and a seaming or curling flange for the end closure. Such flange is folded or rolled inwardly to capture an end closure including a plastic frame that defines a dispensing opening and has bonded thereto an end panel to be peeled back to allow dispensing of product. A seaming flange is folded about a peripheral portion of an outer boundary of the frame member and then the two are enfolded generally flat above the supporting ledge of the container to form an inwardly directed seam. A modified end closure comprises a molded plastic frame member which matches the configuration of a ledge portion of the container so the seaming flange and peripheral border portion of the frame member can be rolled together in an inwardly directed curl. The closing operations can be performed without axial pressure on the container wall so they can be thinner than normal.

Abstract: This relates to an end closure for conventional types of containers which may be in the form of glass or plastic jars and bottles or in the form of specially formed metal containers having a folded outwardly projecting annular rim at the top thereof. The end closures are constructed so as to be snapped in place on the containers thus retaining the closures on and keeping the containers closed by a mechanical interlock between the respective closure and container. Further, the end closures have heat-bondable surfaces which when subjected to low temperature heat, such as by heating the rims of the containers or by heating the packaged product within a retort cooker, the heat-bondable surfaces of the end closures will bond to the touching surfaces of the container.

Abstract: In accordance with the present invention, an irreversible tamper evident system for a button closure is provided. The irreversible tamper evident system is provided by a color change system carried by the flexible button portion of the closure. The color change system comprises an indicator coating over a dark colored substrate coating. The indicator coat is preferably colored with a light colored transparent colorant such as an orange colored fluorescent dye. The indicator coat is preferably a liquid material which can be cured by evaporation, heat, UV irradiation or the like, to form a solid layer. When the substrate layer and indicator layer are in intimate contact, a first color is observed. Depending upon the relative colors used for this substrate and indicator layers, this first color can be a combination of the colors of the two layer or can be primarily the color of the substrate layer.

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.
