摘要： A reclosable closure for containers of the type used for keeping or storing product for some time following initial opening of the container. Typical uses would be for snack foods such as candies, peanuts, etc., and powdered products such as sugar, coffee, tea and other beverage mixes and the like. The closure also is adaptable for use with canned vagetables and meats and also with non-food products such as, for example, nails, tacks and a myriad of similar hardware items. The preferred closure includes an end panel and a ring-shaped frame member which are fused or otherwise adhered together during insert-injection molding of the frame member. Means are provided on the frame member for contacting an edge of the end panel, or an integral pull tab thereon, for restraining the end panel in a position for reclosing the container.

摘要： A closure (10) for a container (32), and a method for producing the same, wherein the closure comprises an end panel (24) and a plastic frame member (12) connected together and which can be placed over, or snapped onto, and then the frame member can be permanently attached and hermetically sealed to the flange of a metal, glass, plastic or composite container or can. The interface of the end panel (24) and frame member (12) is such as to hermetically seal the container and yet the end panel can be readily peeled from at least a portion of the frame member for gaining access to the interior of the container. A pull tab (26), or ring, is provided to assist in peeling the end panel to an open position. Depending on the manner of attaching or securing the end panel to the frame member, separation or peeling can result from an adhesive failing or from a cohesive failing of the material forming the frame member, or the end panel, or the adhesive.
摘要翻译：一种用于容器（32）的封闭件（10）及其制造方法，其中所述封闭件包括连接在一起的端板（24）和塑料框架构件（12），并且可以放置在或夹在，然后框架构件可以永久地附接并气密地密封到金属，玻璃，塑料或复合容器或罐的凸缘上。端板（24）和框架构件（12）的界面是为了气密地密封容器，而端面板可以容易地从框架构件的至少一部分剥离，以便进入容器的内部。提供拉片（26）或环，以帮助将端板剥离到打开位置。根据将端板连接或固定到框架构件的方式，分离或剥离可能由于粘合剂失效或由形成框架构件或端板或粘合剂的材料的内聚失效引起。

摘要： This relates to an end closure (16, 40, 60) for conventional types of containers (10) 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 snappable in place on the containers thus retaining the containers closed by a mechanical interlock. Further, the end closures have heat-bondable surfaces (32, 50, 70) 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 (10).

摘要： Tooling (20) is for forming an article (66) having an injection molded peripheral frame (52) defining an opening closed by an panel insert (48, 140). The insert is struck from sheet material (40) and, together with an associated punch (36), cooperates with a split mold (24, 26) to completely define a mold cavity (30) for injection molding of the article. The panel insert forms a portion of the walls of mold cavity (30) and is automatically heat bonded to the frame during the molding operation. The panel insert may be peeled from the frame by using a pull tab (76, 142). The pull tab (76) can be formed by punch (36). Pull tab (142) can be separately formed outside of the mold from sheet material, then folded and staked thereto, after which the panel insert (140) is punched from the sheet material so that the pull tab is simultaneously trimmed to its preferred shape.

摘要： A metal can (10, 50, 80, 110, 130) is closed by a specially prepared end closure (18, 64, 88, 120, 140). The open end (20) of the container is outwardly folded to define a supporting ledge and a seaming flange for the end closure. The seaming flange is to be folded or rolled inwardly for defining a seaming flange. The end closure is constructed with a frame member (26, 66, 90, 122, 142) defining a dispensing opening and having an end panel (28, 78, 92, 124, 144) which may be peelably removed to dispense the product from the container. Heat may be applied to the seam during the formation thereof or during a subsequent process step.

摘要： Closures for containers, such as cans and the like, wherein the closure is comprised of an end panel and a frame member which, preferrably, are attached together during an insert-injection molding operation used for forming the frame member. Depending upon the respective materials, the attachment therebetween may comprise heat-bonding or adhesives, and the like. The various end panels have a displaceable panel portion for providing an opening in the closure to provide access to the product(s) within the container. The various panel portions are defined by weakening lines, perforations or cut lines in the end panel and molded runners for "repairing" and/or sealing weakened or lanced portions of the end panels. The molded runners provide beam strength for protecting against excessive bulging during autoclave or other sterilization processes and against buckling during vacuum processing.
