Abstract
Systems and methods for controlling oxygen ingress in cap closures are herein disclosed. According to one embodiment, the current apparatus includes a cap and a cap liner. The cap liner includes a primary oxygen barrier layer and a first diffusive layer. A first side of the first diffusive layer is adjacent to a first side of the primary oxygen barrier layer. A second &de of the first diffusive layer contacts a lip-sealing surface of a bottle. The oxygen transmission rate of the cap liner is controlled by varying a thickness of the first diffusive layer.
Claims27
An apparatus, comprising:
- a cap;
- and
- a cap liner, wherein the cap liner comprises a primary oxygen barrier layer and a first diffusive layer, wherein a first side of the first diffusive layer is adjacent to a first side of the primary oxygen barrier layer, wherein a second side of the first diffusive layer contacts a lip-sealing surface of a bottle, and wherein varying a thickness of the first diffusive layer controls an oxygen transmission rate of the cap liner.
A method, comprising:
- selecting a first diffusive layer;
- selecting a primary oxygen barrier, wherein a first side of the first diffusive layer is adjacent to a first side of the primary oxygen barrier layer, wherein a second side of the first diffusive layer contacts a lip-sealing surface of a bottle, and wherein the first diffusive layer and the primary oxygen barrier layer are part of a cap liner;
- and
- varying a thickness of the first diffusive layer to control an oxygen transmission rate of the cap liner.
