Embodiment Construction

[0086] Please refer to Figure 1 and figure 2 , the present embodiment is a container closure assembly especially for carbonated beverage containers. The main features of this assembly are similar to those described and claimed in International Patent Applications WO95 / 05322, WO97 / 21602 and WO99 / 19228, the entire contents of which are hereby incorporated by reference. However, it is important to point out that the threads provided on the cap and neck of the present invention are reversed compared to the cap assemblies described in those applications. That is, the assembly detailed in the earlier patent application has a short threaded section at the closure skirt and a longer threaded section at the neck. However, the present invention provides a short threaded section at the neck and a longer threaded section at the closure skirt.

[0087] The assembly of this embodiment includes a container neck 10 and a closure 12 for a carbonated beverage container. Both the container ne...

Abstract

A threaded container closure assembly, comprising: a container neck (10) having an opening; a closure (12) for said neck, the closure having a base portion (22) and a skirt portion (24); a first screw thread on the neck, said first screw thread comprising one or more first thread segments (16), and a second screw thread on an inner surface of the skirt of the closure, said second screw thread comprising one or more second thread segments (26); a first locking projection (44) on the container neck separate from the first thread segments and a second locking projection (46) on the inner surface of the skirt of the closure separate from the second thread segments, said first and second locking projections being configured to resist unscrewing of the closure from the fully engaged position on the container neck after the closure has been secured or resecured on the container neck until a predetermined minimum opening torque is applied; wherein said first and second locking projections longitudinally overlap the first or the second thread segments when the closure is in the fully engaged position on the container neck.

Description

【Technical field】 [0001] The present invention relates to an improved screw closure assembly for containers. 【Background technique】 [0002] Current commercial mass-produced beverage containers use threaded and continuous threaded closures on the neck of the container. The thread comprises a single, substantially continuous thread portion on the neck of the container, with a small pitch angle, typically less than 5°. The small pitch angle is required to ensure that the closure does not unscrew itself. When the closure is secured to the container neck, the small pitch angle can also provide the necessary torque to achieve an airtight pressure seal between the closure and the container neck. The small pitch of the continuous thread also generally means that complete removal of the existing closure from the container neck typically requires a rotation of more than 360°. [0003] Disadvantages of these small pitch continuous threads include the laborious rotation required to ...
