Disclosed herein are integrated closures for a container The integrated closure includes a base and a lid connected to the base via a hinge, where the lid and hinge are configured to permit the lid to open towards a center of the integrated closure, and a film. The film including a first portion connected to at least a portion of a bottom surface of the base, a second portion connected to at least a bottom surface of the lid, and a third portion connected to the first portion and releasably connected to the second portion. The integrated closure including a tamper indicator membrane connected to an edge of the lip and a corresponding edge of the base. The base further including a retention mechanism, the retention mechanism configured to engage and retain the lid in an open position.

A molded article comprising a container top is disclosed. The molded article includes a threadless frame defining an opening, a flip cap located substantially coplanar with, and integrally formed with, the frame, a compound hinge between the frame and the flip cap, the hinge allowing the flip cap to rotate about the hinge to rest on top of the frame, an in-mold lidding film having a perimeter molded to the frame such that the in-mold lidding film covers the opening defined by the frame, wherein the in-mold lidding film is removable from the frame, and a pull tab, formed from the in-mold lidding film, that extends past the opening defined by the frame.

A container a side surface and a rim that defines an opening and an axis; a closure for the container; the container and closure having cooperating threads to move the closure axially as it is rotated; the closure having a seal against the side surface of the container; the thread portions of the container and closure are configured such that, as the closure rotates relative to the container, the seal moves parallel to the axis contacting three regions on the side surface of the container: a first region, configured such that, as the seal is moved across the region, the seal changes between states in which it is uncompressed and compressed between the container and closure; a second region, where the fluid bypasses part of the seal; and a third region where the seal forms a fluid-tight seal between the side surface and the closure.

A cap for a container is made of a material at least part of which is derived from natural fibres. The cap comprises a cup-shaped body having a skirt which extends around an axis and a transversal wall arranged transversally to the axis. A cavity is defined inside the cup-shaped body. The cup-shaped body is delimited by an inner surface facing the cavity and by an outer surface facing the opposite way to the cavity. At least one projecting element projects from a surface of the cup-shaped body selected from either the inner surface or the outer surface. At least one recess is provided at the projecting element on another surface of the cup-shaped body selected from either the outer surface or the inner surface.

The invention provides a container lid (1) comprising: a closure panel (7) comprising an inside surface and an outside surface; a container fastening portion (9); and a liner (5) comprising one or more layers, connected to the inside surface of the closure panel, wherein the liner or at least a lowermost layer of the liner is detachable from the closure panel, characterized in that said container lid comprises a resilient portion (15) located between said closure panel and said fastening portion.

A polyethylene composition having increased environmental stress crack resistance (ESCR) is comprised of a polymer blend of a high density polyethylene (HDPE) and polyethylene glycol (PEG). The PEG is present in the polymer blend in an amount of from 0.5 wt. % to 15 wt. % by total weight of the polymer blend. The PEG may have an average molecular weight of from 2000 to 40,000. In a method of forming a polyethylene composition having increased ESCR, a HDPE is modified by combining the HDPE with PEG in a polymer blend, the PEG being present in an amount of from 0.5 wt. % to 15 wt. % by total weight of the polymer blend. The polymer blend can be formed into an article of manufacture, such as a bottle cap.

Polymer compositions may comprise propylene, present in a range of 80 to 95 wt % of the polymer composition, and two comonomers selected from a group comprising ethylene and C4-C10 alpha olefins, wherein the polymer composition has a total content of the comonomers in the range of 5 to 20 wt % of the polymer composition. Cap liners may be formed from the polymer compositions. Caps may comprise a closure formed from polypropylene and a polypropylene-based cap liner that lines at least a portion of the closure.

A manufacturing method of a cap (100) includes: supplying a first resin material to a molded product (111A) having a top plate portion (121) and a skirt portion (122) integrally formed on the top plate portion (121) through a corner portion (123); molding the first resin material of the molded product (111A) disposed in a first lower mold (21) into a sliding layer (141) with a first upper mold (22); supplying a second resin material to the sliding layer (141); molding the second resin material of the molded product (111A) disposed in a second lower mold (31) into a sealing layer (142) with a second upper mold (32); taking out a sealing member (112) in the molded product (111A); and inserting the sealing member (112) into another molded product (111A).

A cap for a container comprises: a retaining ring suitable for being associated with a neck of the container, the retaining ring extending about an axis; a closure element for opening or closing an opening defined by the neck of the container; a hinge structure interposed between the closure element and the retaining ring so as to allow the closure element to be rotated relative to the retaining ring.

The retaining ring and the closure element are separated by a separation line, which extends externally of the hinge structure.

The hinge structure comprises at least one connection band which connects the closure element to the retaining ring, the connection band being defined inside a recess provided in a side wall of the cap, the side wall extending about said axis.
