Abstract
A bottle closure includes a closure element and a cap element. The closure element is configured to be received at least in part within a portion of a bottle. The closure element includes a first portion of a first material and a second portion of a second material. The second material has a lower durometer hardness than the first material. The second material is moldably bonded to the first material. The closure element defines a hollow interior. The cap element is coupled to the closure element.
Claims19
A bottle closure comprising:
- a closure element configured to be received at least in part within a portion of a bottle, the closure element comprising a first portion of a first material and a second portion of a second material, the second material having a lower durometer hardness than the first material, the second material moldably bonded to the first material, the closure element defining a hollow interior;
- the first portion including a plurality of spring elements connected to each other at respective first and second ends thereof;
- and
- a cap element coupled to the closure element,
- wherein the first portion of the closure element comprises a fragmented cup structure having a rounded side structure formed of the plurality of spring elements and a bottom structure, the rounded side structure including a plurality of axial slots formed between adjacent spring elements of the plurality of spring elements, said slots extending partially into the bottom structure, and
- wherein the first portion of the closure element further comprises a shelf extending radially outward of a top of the fragmented cup structure, the shelf configured to engage and retain the cap element, the cap element fixed relative to the closure element in an axial direction.

A bottle closure comprising:
- a closure element configured to be received at least in part within a portion of a bottle, the closure element comprising a cup structure having an open end and a closed end, the cup structure comprising a first material and a second material, the second material having a lower durometer hardness than the first material, the second material moldably bonded to the first material, the cup structure defining a hollow interior;
- and
- a cap element coupled proximate to the open end of the cup structure of the closure element without extending into the hollow interior defined by the cup structure.
A bottle closure comprising:
- a closure element configured to be received at least in part within a portion of a bottle, the closure element comprising a first portion of a first material and a second portion of a second material, the second material having a lower durometer hardness than the first material, the second material moldably bonded to the first material, the closure element defining a hollow interior;
- and
- a cap element coupled to the closure element and fixed relative to the closure element in an axial direction;
- wherein the first portion of the closure element comprises a fragmented cup structure having a rounded side structure and a bottom structure, the rounded side structure including a plurality of axial slots formed therein, said slots extending partially into the bottom structure, and wherein an interior surface of the fragmented cup structure defines the hollow interior and is free from engagement with any surface of the cap element.
