Abstract
A closure includes a hinged sealing element including a top wall and a first skirt. The first skirt has a sealing formation allowing engagement of a mating sealing formation of a bottle. A second skirt has an attachment formation engageable with a mating attachment formation of the bottle. A plurality of frangible members is attached to each of the skirts. A pair of hinge members is attached between the first and second skirts. A biasing member is attached to the first skirt between the hinge members and extending downwardly from the first skirt to interact with a neck portion of the bottle such that the sealing formation of the first skirt and the mating sealing formation of the bottle are biased toward each other.
Claims20
A closure comprising:
- a hinged sealing element comprising a top wall and a first skirt extending downwardly from the top wall, an inner surface, an outer surface, the inner surface comprising a sealing formation configured to engage a container, the first skirt extending from the top wall to a lower edge of the first skirt;
- a second skirt pivotally coupled to the hinged sealing element, the second skirt defining an inner surface, an outer surface, and a top edge, the inner surface configured to couple to the container;
- a plurality of frangible members extending between the first and second skirts, the plurality of frangible members configured to provide a visual indication when broken that the closure has been opened a first time;
- a first hinge member extending between the first and second skirts, the first hinge member comprising a first upper portion coupled to the first skirt, a first lower portion coupled to the second skirt, and a first middle portion extending between the first upper portion and the first lower portion, wherein the first middle portion is thinner than at least one of the first upper portion and the first lower portion;
- and
- a second hinge member extending between the first and second skirts;
- the first upper portion comprising an inner edge closest to the second hinge member and an outer edge furthest from the second hinge member, wherein the outer edge of the first upper portion extends a first distance towards the second skirt and the inner edge of the first upper portion extends a second distance towards the second skirt that is further than the first distance.
