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.
Claims9
An apparatus, comprising:
- a cap;
- and
- a cap liner, wherein the cap liner comprises a primary oxygen barrier layer that is approximately 1 mil, an adhesive layer that is 1 mil-7 mil, and a first diffusive layer that is approximately 2 mil,
- wherein the primary oxygen barrier layer comprises one or more of tin foil, aluminum foil, PVDC, Polyester (PET), EVOH, metalized PET (by vacuum deposition), metalized LDPE, metalized ultra low density polyethylene (ULDPE), metalized linear low-density polyethylene ((LLDPE), and metalized high-density polyethylene (HDPE),
- wherein the adhesive layer is directly adjacent to the primary oxygen barrier layer and the first diffusive layer,
- wherein a first side of the first diffusive layer is directly adjacent to a first side of the adhesive layer,
- wherein a second side of the first diffusive layer contacts a lip-sealing surface of a bottle, and
- wherein a thickness of the adhesive layer is variable to control an oxygen transmission rate of the cap liner such that the cap liner has a total oxygen transmission rate increase as the thickness of the adhesive layer increases.
