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.

An inner surface of the tubular side wall includes a thread. An inner surface of the upper lateral wall includes a retaining extension. The fitment includes a side wall extending from an upper lateral surface to an open lower end. The upper lateral surface of the fitment includes a central aperture having a shape that is reciprocal to a shape of the retaining extension of the cap. The fitment is selectively secured within the cap by directly engaging the central aperture of the fitment with the retaining extension of the cap.

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.

What is presented is a method of forming a closure with a sealing gasket in an injection molding machine that has a center rotating cube. The center rotating cube comprises a plurality of mold back halves each comprising cores and a thread unscrewing mechanism. Each core is shaped to form a closure that has a thread and an anti-rotation feature. The method comprises the steps of forming a closure with a through hole, rotating the core to create a gap between the formed closure and the core, and injecting a compressible material through the through hole and into the gap to form a sealing gasket.

Adhesive compositions that replace gaskets and liners in sealing applications for packages that are detachable with hand force are described. The adhesive compositions are particularly useful in preventing leaks and spillage during storage and transport of its packaged contents. Advantageously, the adhesive composition provides packages with (1) a removal torque of from about 4 to about 20 in-lb and (2) resealable torque on subsequent openings of from about 2 to about 15 in-lb, measured in accordance to ASTM D2063.
