CONTAINER CLOSURE WITH MEMBRANE-PIERCING PUNCH
A container closure includes a body formed to include a product-dispensing spout and to mate with a filler neck of a bottle or other container. A thin membrane seal is coupled to the bottle filler neck to close and seal a top opening of the bottle filler neck.
This application claims priority under 35 U.S.C. § 119(e) to U.S. Provisional Application Ser. No. 60/743,102, filed Jan. 6, 2006, which is expressly incorporated by reference herein.
BACKGROUNDThe present disclosure relates to closures for mounting on the top of bottles or other containers, and in particular, to a container closure including a “flip-top” cap. More particularly, the present disclosure relates to a container formed to include a top opening covered by a thin membrane arranged to close and seal the top opening.
SUMMARYA package in accordance with the present disclosure includes a container, a seal arranged to close an opening into an interior region formed in the container, and a closure coupled to the container to cover the seal. In illustrative embodiments, the closure includes a body adapted to be coupled to the container and a seal opener mounted for movement relative to the body to pierce the seal while the closure body is coupled to the container. In illustrative embodiments, a thin membrane made of sealing material provides the seal.
According to the present disclosure, a closure includes a body formed to include a product-discharge outlet and adapted to mount on a filler neck of a bottle or other container. The closure also includes a membrane opener coupled to the body for movement relative to the body between a raised position lying away from a membrane seal closing an open mouth into the filler neck of the bottle or other container and a lowered position piercing the membrane seal. Once the membrane seal is pierced, fluid retained in an interior region of the bottle or other container can be discharged through the product-discharge outlet.
In illustrative embodiments, the closure also includes a flip-top cap appended to a hinge arranged to support the flip-top cap for movement from a closed position on the body covering the product-discharge outlet to an opened position away from the body uncovering the product-discharge outlet. In use, once the flip-top cap (or other cap) is moved to an opened position to expose the membrane opener, a user pushes downwardly on the opener to move the opener relative to the body to pierce the membrane. Fluid material retained in the bottle can then flow through the pierced membrane into and through the product-discharge outlet for consumption by the user.
In one illustrative embodiment, the membrane opener is coupled to a top wall of the body and located in side-by-side relation to the product-discharge outlet. In another illustrative embodiment, the membrane opener is coupled to the body and located, at least in part, in the product-discharge outlet and is formed to include fluid-discharge ports to allow fluid material to flow from the bottle, in sequence, through (1) the opening formed in the pierced membrane, (2) the fluid-discharge ports formed in the membrane opener, and (3) product-discharge outlet.
Additional features of the disclosure will become apparent to those skilled in the art upon consideration of the following detailed description of illustrative embodiments exemplifying the best mode of carrying out the disclosure as presently perceived.
