A closure that is retainable with a container is disclosed.

A synthetic-resin container lid having tamper-evident characteristics, which is not separated in its entirety from a mouth-neck portion of a container even after the mouth-neck portion of the container is unsealed, is manufactured rapidly and inexpensively. A plurality of scores (26, 30, 32, 34, 36, 38) are formed, as post-processing, at predetermined positions in an incomplete container lid formed with no scores.

A closure includes: a body having a skirt wall in which an internal thread is formed; and a cylindrical tamper evident bottom portion which is connected to the skirt wall via a plurality of breakable bridge portions, and in which an engaging means to be engaged with an engaging jaw portion is disposed on an inner peripheral surface of the tamper evident bottom portion. A protruding piece protruding downward is disposed on the skirt wall of the body. An unbroken connecting piece is disposed to connect the skirt wall of the body and the tamper evident bottom portion and to allow the body to be moved upward with respect to the tamper evident bottom portion. An extending portion is formed at an engaging piece serving as the engaging means at least in an angle region where the protruding piece is present.

The present invention relates to a tethered screw plastic stopper, comprising a tamper shell positioned around the stopper. The tamper shell includes a retaining feature operable to cooperate with a top ring extending outwardly around a bottle neck. The stopper also includes a roof connected to the tamper shell through a hinge and separably connected to the tamper shell through a weakness line, wherein the tamper shell may be moved downwardly in rotation into an opened position.

A cap includes a cap body including a top plate portion and a skirt portion; a sealing member that is a separate member from the cap body and is provided in the cap body, the sealing member having an outer diameter smaller than an inner diameter of the skirt portion; a plurality of locking portions provided in a circumferential direction of the skirt portion, and configured to regulate a movement of the sealing member in a direction away from the top plate portion and support the sealing member; and a plurality of regulating portions provided in the circumferential direction of the skirt portion, protruding inward in a radial direction than an inner peripheral surface of the skirt portion, and configured to regulate a radial movement of the sealing member.

The invention relates to a closure consisting of a screw cap (10) with a tamperproof strip (3). The screw cap has at least one cylindrical cap casing (2) with an inner thread and a circumferential tamperproof strip at the lower open end of the cap casing, said tamperproof strip being connected to the lower edge of the cap casing along easily tearable weakness lines (13, 14), wherein the tamperproof strip remains captively connected to the cap casing after a tearing process along the weakness lines by means of holding strips (15, 16). The aim of the invention is to design a captive screw cap with a tamperproof strip in such a manner that after the screw cap has been unscrewed and released from the bottleneck opening, the screw cap is folded away or tilted into a position in which the screw cap does not interfere with the additional use of the bottle or with pouring or drinking out of the bottle and can remain there without additional measures. According to the invention, this is achieved in that the holding strips are formed by two weakness lines, each of which is interrupted at least once in the circumferential direction and which partly overlap in the circumferential direction and run at an axial distance to each other at least in the overlap region. The separating web (11, 12) of each of the two weakness lines is bridged by the respective other weakness line preferably at an axial distance.

The present invention relates to a closure device for aseptic paper or paper-based containers which can be used for storing liquid products. In particular, the present invention relates to a closure device comprising three parts. It has a pour spout which can be fixed to an outer surface of the container, a cap having a re-sealable lid portion being permanently connected to a retainment portion via a hinge and a barrier breaking device moveably attached to the pour spout and configured to break a liquid tight seal of the paper or paper-based container upon twisting said cap. The invention also relates to an assembly comprising a container and said closure device and a method for providing the assembly.

Container assembly comprising a container and a closure, wherein the container is made of a crystallisable polymer material and comprises a neck portion with an outer cap surface and defines an outlet opening, the neck portion being configured for receiving the closure, wherein the closure includes a closure cap made of a crystallisable polymer material and has an inner cap surface, the closure cap being matched to the neck portion of the container to cover the outlet opening in a closed state, wherein the inner cap surface of the closure cap contacts the outer cap surface of the neck portion when the container assembly is closed, and wherein the material of the inner cap surface of the closure cap and/or of the outer cap surface of the neck portion is crystallised, to allow the container assembly to be opened after being closed for an elongated period of time.
