Disclosed herein are fusion packaging and fusion packages. One package includes a frame configured to provide structure for the package, a sidewall fused to the frame, and a tethered cap connected to one end of the frame. Another package includes a sleeve configured to provide structure for the package, a tethered cap fused to one end of the sleeve, and a seal configured to be fused to a remaining end of the sleeve after the package is filled with content. Another package includes a frame configured to provide structure for the package, a film fused to the frame, a cap connected to one end of the frame, the cap including a structure to retain the cap after removal from the frame, and a seal connected to another end of the frame, where one of the cap and seal are connected to the frame after material placement.

Disclosed herein are fusion packaging and fusion packages. A package includes a frame which provides structure, a sidewall fused to the frame, and a cap connected to one end of the frame. Another package includes a sleeve, a cap fused to one end of the sleeve, and a seal configured to be fused to a remaining end of the sleeve after filling with content. Another package includes a frame, a film fused to the frame, a cap connected to one end of the frame, and a seal connected to another end of the frame, where one of the cap and seal are connected to the frame after material placement. Sealed edges are formed at junctures between a frame, sleeve, or cap and a sidewall or film when frame, sleeve, or cap material embeds with sidewall or film material.

A can lid made of a resin laminate steel sheet for a resin-metal composite container, includes: a top sheet portion; and a curved portion located at an outer periphery of the top sheet portion, in which the resin laminate steel sheet includes a steel sheet, a thermoplastic polyester-based resin layer provided at a first surface of the steel sheet, a modified polypropylene-based resin layer provided at a second surface of the steel sheet, a polypropylene-based resin layer, and an ethylene-propylene copolymer resin layer, a melting point of the ethylene-propylene copolymer resin layer is 135° C. or higher and 150° C. or lower, a melting point of the thermoplastic polyester-based resin layer is higher than a melting point of the polypropylene-based resin layer by 40° C. or more, and a range of a proportion of the ethylene component in the ethylene-propylene copolymer in the ethylene-propylene copolymer resin layer is 1.0 mass % or more and 45.0 mass % or less.

A container has a head piece (7). The container can be or is filled with a medium and is produced of plastic materials using a blow molding, filling, and sealing method. A transition region (13) is between the container (1) and a first type of a head surface (11) arranged on the head piece (7) at an end face, can be penetrated by a piercing or cutting part and extends with a specifiable curvature. A second type of a head surface (41) has a specifiable curvature, which is the same as the curvature of the head surface (39) of the first type, but preferably is different from it and is present on the head piece (7). The head surfaces transition into each other such that a whole surface is formed, which whole surface spans the free end of the transition region (13) directed away from the container (1). The head piece (7) is an integral component of the container (1).

A foil for closing an opening in a container, such as an easy opening container, includes foil to be adhered to the container. The foil includes a tab for releasing the foil from the container. The tab is folded on the foil and connected thereto via a connector and the tab is provided with a breakout device such that upon actuating the tab a visible and irreparable broken out part is formed and adhered to the foil.

The invention relates to a container having a head piece (7), which container can be or is filled with a medium and is produced of plastic materials using a blow molding, filling, and sealing method, comprising a transition region (13) between the container (1) and at least one first type of a head surface (11), which is arranged on the head piece (7) at an end face and can be penetrated by means of a piercing or cutting part and extends with a specifiable curvature. Said container is characterized in that at least one second type of a head surface (41), which likewise has a specifiable. curvature, which is the same as the curvature of the head surface (39) of the first type, but preferably is different therefrom, is present on the head piece (7), that the head surfaces transition into each other in such a way that a whole surface is formed, which spans the free end of the transition region (13) directed away from the container (1), and that the head piece (7) is an integral component of the container (1).
