The present invention relates generally to a container that may be sealed and reclosed with a threaded closure. More specifically, the present invention relates to methods of manufacturing a metallic container having an opening with inwardly facing threads. The threads are formed on the metallic container by pressing a neck portion of the metallic container against closure threads of a threaded closure which is inserted at least partially into the opening. The container threads may optionally be formed while the threaded closure is in tension. In this manner, after the container threads are formed, the closure threads can apply a force to the container threads such that the threaded closure is in tension. The container opening may be selectively sealed and reclosed with the threaded closure which releasably engages the container threads. Novel apparatus and methods of sealing metallic containers and forming threads on the metallic containers are also disclosed.

A shaped metal container comprising less metal than prior art shaped metal containers while still able to handle sufficient axial load and undergo shaping processes, including necking, without wrinkling, buckling, collapsing or other physical defect is disclosed. Processes for shaping a metal container having a sidewall of variable thickness, wherein a portion of the sidewall having a variable thickness is shaped using a die or dies are also disclosed.

Coupling of conveyor belt modules A module (2) for a modular conveyor chain, comprising a link portion (3) made of sheet metal that includes a substantially elongate conveying body (4), the conveying body having a central hinge loop (5A) on one longitudinal side thereof and a pair of offset hinge loops (5B) on an opposite longitudinal side thereof that are interspaced to receive the central hinge loop of a link portion of a consecutive module therebetween. The central hinge loop and/or or the offset hinge loops are distanced with their free end(s) from a bottom face of the conveying body to form a through pass aperture (16) through which a hinge pin (12) held in the hinge receiving space(s) of the hinge loops of other module may pass transversely to its axis into or out of its hinge receiving space.

A bottle-shaped can in which flatness and circularity of a neck portion are improved. An upper incomplete thread portion is formed at an upper end of a thread. A height of the upper incomplete thread portion is shorter than an average height of the thread, and increases gradually toward the average height. A length of the upper incomplete thread portion between a first point and a second point is set in such a manner that an angle between a line drawn between the first point and a center point of the neck portion, and a line drawn between the second point and the center point of the neck portion falls within a range from 20 degrees to 60 degrees.

A cam for use in trimming earing from an open end of an article following at least one forming process. The cam includes a cam profile for actuating a cam follower to which the article is coupled. The cam profile includes a generally sloped rising portion, a generally sloped retracting portion, and a working portion bridging the rising portion and the retracting portion. The working portion includes generally sloped sections separated by at least one recess or dwell.

An apparatus and a method for accurately processing a neck portion of a bottle-shaped can without changing a posture of the can. An inner tool is inserted into the neck portion from the bottom of a can body to form a stepped portion, and comprises a first forming section having a diameter smaller than an inner diameter of a neck portion. An outer tool comprises a second forming section that is opposed to the inner tool. The stepped portion is formed on the neck portion by sandwiching the neck portion by the first forming section and the second forming section. The inner tool further comprises a holding member that is situated coaxially with the can body to be contacted to an inner surface of the can body. The holding member is attached to the inner tool while being allowed to move in a radial direction together with the can body.

An alignment assembly for a press assembly is provided. The alignment assembly includes a number of alignment elements. The alignment elements include a number of moving alignment elements. The moving alignment elements are coupled to an upper tooling assembly that moves between a first and second position. As the upper tooling assembly moves, the moving alignment elements move between a first position and a second position corresponding to the upper tooling assembly first position and a second position. The moving alignment elements are structured to move the shell from the initial alignment position to an intermediate alignment position. Thus, as the upper tooling assembly moves from the first position to the second position, the moving alignment elements contact a shell and move the shell from an initial alignment position to an intermediate alignment position.

A primary beverage container includes a container body (102) and a container end (230). The container body includes an outer wall (104) and an inner wall (106). The outer wall defines an outer cavity (116), and the inner wall defines an inner cavity (122) with an opening (124) at a top end (108) of the container body. The inner wall is positioned within the outer cavity such that between the top end and a bottom end of the container body, the inner wall is spaced apart from the outer wall within the outer cavity. The container end is joined to the top end of the container body and covers the opening of the inner cavity.

A metal cup and method of forming the same is provided. Metal cups of the present disclosure comprise a plurality of thin, straight-walled sections and a tapered profile. A domed portion is provided in the bottom of the cup. The cup may comprise a disposable cup, a reusable cup, or a recyclable cup.
