The present invention relates to an assembly for the closure of a tube. The assembly includes a cap that includes a punch adapted to cut a seal. The seal is adapted to seal a neck of a tube head. The cap is configured to be fixed to the neck in a first position, known as the standby position, and a second position, known as the use position. The assembly also includes a ring movably fixed to the cap. The assembly is configured to allow the passage from an extended position, with the aim of the punch being protected by the ring in the standby position of the cap, to a retracted position, with the aim of the seal being pierced by the punch in the use position of the cap, a passage of the assembly from the extended position to the retracted position being effected by a sliding of the cap through the ring.

A closure is configured to mate with the neck finish of a container. In embodiments, the closure includes an outer wall portion; an upper surface portion; a plug portion including an inner diameter portion; and a plurality of lugs configured to engage a neck finish of the container. In embodiments, a portion of the plug portion engages an inner diameter portion of an upper portion of the neck finish of the container.

A reconfigurable container having an inner and outer wall wherein the inner wall may be disconnected from the outer wall, inverted and re-attached to form a container having a larger volume.

A container assembly including a container and a metallic closure. The container includes a polymeric body and a polymeric finish. The polymeric finish includes a plurality of threads. A lug lock is associated with each one of the plurality of threads. The metallic closure includes at least three metallic lugs configured to cooperate with the plurality of threads to couple the metallic closure to the polymeric finish.

A universal bottle cap capable of threadably engaging two or more bottles of a different thread arrangement having a substance retained therein. The universal bottle cap threadedly engages a bottle containing a beverage therein. Such universal bottle cap includes a cylindrical member closed at a first end thereof and open at a second end thereof. There is a threaded portion disposed on an inner surface of the cylindrical member for engaging a threaded end of such bottle. A capsule like device is disposed inside the cylindrical member adjacent the closed end for retaining a substance to be dispensed into a beverage in such bottle. A device for piercing the capsule engages each of the threaded portion of the bottle cap and the capsule for piercing the capsule as the universal bottle cap is threaded onto such bottle thereby releasing contents of the capsule into such beverage for mixing therewith.

Disclosed is a test barrel, to prevent a test liquid in the barrel from sputtering into a connection gap due to shaking of the barrel to hence cause contamination, improve the measurement accuracy in case of multiple tests, and meanwhile improve the operability of screwing on and screwing off the entire device during use of the device. The above technical objective of this utility model is implemented by employing the following technical solution: a test barrel, comprising barrel lid and a barrel body; wherein the threaded rings are arranged on an inner wall of a side face of the barrel lid and an outer wall of an opening of the barrel body, a rotary force applying portion is arranged on an outer wall of the side face of the barrel lid, and during engagement, a liquid blocking washer is arranged between the barrel lid and the barrel body, wherein a radial width of the liquid blocking washer is greater than a thickness of the opening of the barrel body.

Expandable container, made up of a cylindrical container (1), of the type of a soda can, closed at the bottom and open at the top comprising on its outer upper part a thread (2) that will serve to seal the container hermetically by means of a cap (4) and towards the inside a small flange (3) along its entire perimeter, where the screw cap (4) has an internal thread (5) inside, to screw with the external thread of the container (2), and an elastic seal (6) on the upper part of the inner part that will confer tightness to the assembly when the cap is properly tightened; the extensible part is made up of a mobile inner cylinder (7), with a diameter slightly smaller than that of the container, which has a straight perimeter outer flange (8) on its upper edge, which will rest on the top of the container (1), and another flange (9) on its lower edge curved towards the outside that supports the interior wall of the container (1) and that said curved flange (9) carries an elastic joint (10) inside; and when the mobile inner cylinder (7) slides upwards, it does so until the elastic joint (10) located inside the lower flange (9) abuts the lower part of the circular flange (3), the assembly being watertight in that area; and when the mobile inner cylinder (7) is unfolded, the volume of the assembly is increased, so that to the liquid (11) contained in the container another complementary liquid and even some ice can be added, increasing the volumetric level from level (13) to level (14).

A modular bottle (e.g., for holding liquid or dry storage contents) and its various assemblies, components, and structures are provided. The bottle can include a body portion including an open longitudinal end and an interior region, an end cap configured to be secured over the open longitudinal end to enclose the interior region, and a flexible loop. The end cap can include a pair of knobs disposed on a circumferential side surface of the end cap. Each end of the flexible loop can define an aperture that is smaller than a largest diameter of each of the pair of knobs such that each end of the flexible loop is selectively couplable with each of the pair of knobs.

A closure assembly comprising a two-part closure having a metal panel or disc (2) and a ring (3), and a container such as a glass jar (20). The ring (3) is substantially cylindrical with an axially upwardly extending sidewall and has a radially inwardly extending lower edge. The jar (20) terminates in a radially outwardly extending beaded rim (16) and the disc (2) has a curled circumference (8) such that this curl (8) co-operates with the beaded rim (16) of the container to provide a primary seal. In one example, in a metal ring (3), the lower edge is curled with equally spaced lugs (13) on the skirt wall. In a plastic ring, the upper rim feature may be omitted.

A cap includes an upper cap portion to enclose an opening of a bottle and hold a dosage of fluid, a lower cap portion to extend into the bottle and increase the dosage capacity of the cap, and a skirt configured to engage the exterior surface of the bottle to secure the cap to the bottle. The upper cap portion includes a top and a first sidewall having one or more sections that protrude radially away from other portions of first sidewall.
