The invention is directed to a system and method for sealing a closure to a container comprising a die assembly, a mandrel assembly, and a gas evacuation assembly. The mandrel assembly comprises an outer mandrel and an inner mandrel. The outer mandrel is configured to vertically translate and constrain a closure in position. The gas evacuation assembly, which comprises at least one interior channel within the die and one or more channel openings into the interior of the die, suctions gas from the interior of an aligned container when the closure is constrained in position. The inner mandrel translates vertically to insert the closure into the container and a sealing member seals the closure in place.

A kit-of-parts of a cup part and a separate cover together form a coffee cup. The cup part includes bottom wall and a circumferential side wall with a circular flange extending outwardly from an upper end of the side wall. The flange has an outer edge. The cover includes a substantially flat circular central portion configured to engage the upper surface of the cup part and to cover the upper opening. A skirt extends downwardly from the circumference of the central portion and is configured to be bent around the outer edge of the flange. A circular beaded edge defines the end of the skirt, where the beaded edge of the cover extends outwardly from the skirt over a distance the beaded edge being configured to be deformed against an underside of the flange to secure the cover onto the cup part and form the coffee cup.

Closures with a tamper evidence feature that is reshaped to connect it to the container neck are disclosed. Methods and systems for carrying out the methods, and to mold stacks for making the closures are also disclosed. The tamper evidence feature can be a band, a portion of a cylindrical skirt or a panel formed in the cylindrical skirt. The application of heat may deform the band inwardly to create a lip for engaging a flange on the container neck, or it may weld the tamper evidence feature to the flange

The invention relates to a container made of glass or hard plastic having a container neck (52) with a plurality of external thread elements (53, 54, 55, 56, 57, 58), which are offset circumferentially relative to one another, as thread segments. The container can be closed by means of the thread segments by a closure cap made of metal sheet, wherein the closure cap (1, 2) has a circumferential plastic layer (30;30h,30v) on the inside of the cap and on the rim of the cap which has a sealing and retaining action. The closure cap can be pressed onto the container neck (52) and over the thread elements (53, 54, 55, . . . ) during closure and a vertical portion (30v) of the plastic layer can be opened with a rotary movement relative to the thread segments (53, 54, 55, . . . ). The container neck (52) has an upper horizontal end face (52a) as an annular surface which is adapted and suitable to be pressed into a horizontal portion (30 h) of the plastic layer (30;30h,30v) of the closure cap (1.2) under pressure and to produce a seal under pressure. An axial spacing (h54) is defined which extends between axially upper ends (53a, 54a, 55a, 56a, 57a) of the thread segments (53, 54, 55, 56, 57, 58) and a horizontal plane (E52a) through the horizontally oriented end face (52a) of the container neck (52) of the glass container (50). An annular width (b52) of the upper horizontal end face (52a) is defined as an annular surface. A ratio of the axial spacing (h54) to the annular width (b52) is less than 1.35.

The invention is directed to a system and method for hermetically sealing a closure to a container comprising a die assembly and a mandrel assembly. The mandrel assembly comprises an outer mandrel, an inner mandrel, and an ejector disposed within an inner circumference of the inner mandrel. At least the outer mandrel is configured to translate a first distance in a first time period, the inner mandrel and the ejector are configured to translate a second distance in a second time period, the inner mandrel is configured to retract a third distance in a third time period, and the ejector is configured to retract the third distance in a fourth time period.

Method for determining tightness and CCI of containers with a crimp seal closure by providing a container with a closed crimp seal closure, the crimp seal closure having an elastomer section, measuring a determined length between the top of the elastomer section and a position of the container, comparing the length to a predetermined range, and rejecting closed containers with a length outside the predetermined range.

What is proposed is a closure unit consisting of a glass container (50) with external, circumferentially offset threaded elements (54, 55) on a container neck (52) of the glass container, and a closure cover made of sheet metal, wherein the closure cover (1, 2) has an encircling plastics layer (30; 30h, 30v) on the inside of the cover. The closure cover is pressed onto the container neck (52) and can be opened with a rotational movement via the threaded elements (54, 55) and a vertical section (30v) of the plastics layer. The container neck (52) has a horizontal end surface (52a) on which a horizontal section (30h) of the plastics layer rests under pressure in a sealing manner. A central region (11) of the closure cover passes with an adjoining, circumferentially oriented transition zone (11a, 11b, 11c) into an axially downwardly projecting skirt section (12) which ends in a roll-up region (21a, 21; 22). The plastics layer (30; 30h, 30v) is arranged on the inside of the cover in a manner adhering to the transition zone (11a, 11b, 11c) and the skirt section (12). An axial extent (h.sub.0) of the skirt section (12) and a radial dimension (b52) of the horizontally oriented end surface (52a) of the container neck (52) form a first ratio (v.sub.1) which is smaller than three.

A container includes a metal end applied and sealed to an all-thermoplastic container body by a crimp-seaming or double-seaming operation. The metal end has an outer curl joined to a chuck wall that extends down from the curl. One or both of the inner surface of the container side wall and the outer surface of the chuck wall has/have a heat-sealable material thereon. The metal end is crimp-seamed or double-seamed to the container body and the heat-sealable material(s) are heated to soften or melt such that the interface between the chuck wall and the side wall is fused. The interface is oriented along a direction relative to internal pressure exerted on the metal end such that stress on the interface caused by the internal pressure is predominantly shear stress.

A system for assembling a container and closure comprising an expanding collet which has a plurality of pivoting collet segments, each configured to simultaneously pivot radially outward about a pivot point and comprising. The collet comprises a lip that is engagable with the rim of the open end of the container and an angled tip positioned radially inward from the lip and shaped to press a countersink portion of the closure against an interior wall of the container as the collet segments pivot radially outward. As the container and the chuck are brought together, the rim engages with the lips of the collet segments and causes the angled tips of the collet segments to pivot outward toward the interior wall of the container, thereby pushing the countersink portion of the closure against the interior wall of the container.
