Problems solved by technology

[0003] The disadvantages of the aforementioned small pitch angle of the helical thread include: when removing or screwing the cap on the container neck, laborious rotation of the cap is required; additional molding materials are required to form the long helical thread; in addition, due to the small pitch of the thread corners, making it unreliable to separate the security ring from the edge of the closure
[0006] Interestingly, although the top cap of the glass bottle needs to be opened by a bottle opener, and the top cap cannot be sealed on the neck of the bottle to protect the beverage again; bottle of drink
However, beverage containers in the form of various screw caps have not completely replaced glass bottles with top caps.

Embodiment Construction

[0069] Please refer to figure 1 and figure 2As shown, this embodiment is a container closure assembly, particularly suitable for wide mouth containers such as drinking vessels. The assembly includes a container neck 10 and a closure 12 on the carbonated beverage container; the container neck 10 and the closure 12 are all made of plastic materials, preferably, the container neck 10 is made of polyethylene terephthalate It is formed by injection molding or blow molding of ester, and the cover 12 is formed by injection molding of polypropylene.

[0070] Threaded features on container necks and closures and similar components are described and claimed in International Patent Applications WO95 / 05322, WO97 / 21602, WO99 / 19228, WO03 / 045805 and WO03 / 045806, all of which are incorporated herein in their entirety refer to. However, it is important to note that the threads on the closure and neck of the present invention are reversed relative to the threads described in these internati...

Abstract

A container neck and closure assembly, wherein the container neck comprises a first screw thread on an internal surface thereof and the closure comprises a cylindrical plug for insertion into the container neck, said plug having a second screw thread on an outer surface thereof for engagement with the first screw thread to secure and resecure the closure on the neck.

Description

technical field [0001] The invention relates to a container closure assembly having an internal thread on the container neck; the invention also relates to a container having the closure assembly. Background technique [0002] Currently, commercially produced containers utilize threads on the outer surface of the container neck to engage complementary threads on the edge of the inner surface of the closure. Typically, the thread consists of one substantially continuous helical portion on the container neck, which has a relatively small pitch angle, usually less than 5 degrees. The purpose of using a small pitch angle is to ensure that the closure will not loosen naturally; at the same time, when the closure is tightened on the container neck, the pitch angle provides the necessary pressure for an airtight compression seal between the closure and the container neck. regulation. Often, the tight pitch angle of the helical threads also means that the closure needs to be rotat...
