A container assembly including a pouch, spout and closure is provided. The closure includes a tamper-evident band comprising two or more wall sections. Adjacent wall sections of the tamper band may be connected to one another with frangible connectors configured to break upon twist-off of the closure from the spout. The closure also includes one or more support walls supported between an outer wall and central wall of the closure. The closure further includes one or more hinges attaching the ends of the wall sections of the tamper band to the lower ends of the support walls. The hinges are configured to increase the resistance required to break or otherwise distort the frangible connections of the tamper-evident band, so as to prevent or lower the risk of accidental or inadvertent breakage of the tamper-evident band prior to twist-off of the closure from the spout.

The hybrid plug is a single component replacement for three components, the paint plug, conventional plug and capseal in a drum closure. It is formed from a single sheet of metal and has a plug portion and a capseal portion which vary in thickness. The plug portion has a collar and an externally threaded wall with a plug gasket disposed on a plug gasket seat. The capseal portion is provided with ears and scoring to enable separation from the plug portion and with a lining on the inner wall of the capseal portion to safeguard against plug gasket failure. The capseal portion may be recessed at intervals to form dimples which hold the hybrid plug in place in an automated insertion process. The hybrid plug provides a passage for air and gases during paint curing and leak testing without necessitating removal.

A two-piece tamper-evident band assembly for use with a container and closure combination, where the container has a peripheral collar and the closure has a skirt, is shown. The tamper-evident band assembly includes a breakaway band frangibly connected to a staying ring. The staying ring has decreased flexibility where it connects to the container and closure combination, which prevents the assembly from deforming in a manner that will cause the assembly to fail to indicate that the container has been opened. The tamper-evident band assembly also indicates whether the container has been compromised without requiring modification of the container or the closure and can be applied to existing container and closure combinations that lack a tamper-evident system, allowing the assembly to be used with a variety of container and closure combinations.

A tamper-evident closure assembly is provided for a container having a neck defining an opening. The closure assembly includes a base cap configured for securing with the neck of the container. The base cap includes an aperture for providing access to the opening of the container in the neck. The closure assembly further includes an overcap configured for securing with the base cap and configured to cover the aperture in the base cap when the overcap is secured to the base cap. First and second tamper-evidencing members are associated with the base cap and the overcap, respectively. The first tamper-evidencing member provides an indication when the base cap has been removed from the neck, and the second tamper-evidencing member provides an indication when the overcap has been removed from the base cap.

A PET container cap, which provides tight blocking for preservation of contents in a state of being provided on and coupled to an injection part and provides a sealing function enabling awareness of openness, is proposed. The cap includes a cap body which is provided on and coupled to the injection part so as to provide tight blocking for preservation of contents; and an end ring which is integrally formed at the lower side of the cap body, is restricted by an annular protrusion formed at the lower side of the outer circumference of the injection part, exhibits a sealing function enabling grasping of openness of the cap body, and causes transformation in a separation process of the cap body by a user, so that the end ring is simultaneously separated together with the cap body from the injection part.

Disclosed herein are foilless caps. In an implementation, the foilless caps provide sealing of the container without the use of a foil and are environmentally friendly. In an implementation, the foilless caps include tamper evident mechanisms to provide evidence of prior or attempted use. In an implementation, the foilless caps further include tether mechanisms to prevent loss of the cap after opening. In an implementation, the foilless caps provide sealing and resealing of the container with enough closure to maintain freshness. In an implementation, the foilless caps provide a non-backoff feature which may include audible and tactile indications to the user that the container is closed. In an implementation, the foilless caps may provide mechanisms to hold an opened and tethered cap away from the container opening during use.

A method and an apparatus form aluminium screw capsules with a safety ring made of synthetic plastics for tamperproof closing of containers. An aluminium capsule body is inserted into a moulding cavity of a mould conformed and arranged for the overmoulding of a safety ring on an edge of an annular wall of the capsule body. An annular sealing zone is defined for the synthetic plastic material between a first surface of the capsule body and a mould first portion inserted into the central cavity of the capsule body to form a safety ring anchored to the capsule body.

A fresh-keeping bottle includes a volumetric bottle having a bottle cap, a bottle body and a base. The upper end of the bottle body has a liquid squeezing outlet. The lower part of the bottle body is fixed with the base that includes a flexible bottle bottom and a cylindrical support. The upper edge of the bottle bottom is fixed in the inner wall of the cylindrical support. The liquid can be squeezed from the fresh-keeping bottle by pressing with a single hand without leakage. Solid and liquid materials can be separately packed at the upper and lower parts of a package bottle through tinfoil, which is punctured through sharp protrusion of the bottle bottom to mix the solid and liquid materials. The bottle keeps the powder fresh in transmission and storage and can simply mix the solid and liquid material together without needing special work when in use.
