Abstract
A resealable single-piece push-pull dispensing closure is disclosed that includes a circumferential skirt, a top member circumferentially coupled to the skirt, and a sipper spout. The sipper spout extends upwardly from the top member and has a curved sipper surface that truncates to from a substantially flat landing surface. Plural apertures are disposed in the landing surface, and apertures may be disposed at a periphery of the sipper surface. The curvature of the sipper surface has a constant cross section curvature throughout the width of the sipper surface. A user's lip may rest on the sipper surface while drinking directly therefrom, or the top member may have a concave portion in which a user's lip may rest during drinking.
Claims13
A container assembly for liquid contents, comprising:
- a container including a container body and a neck extending upwardly therefrom;
- and
- a re-sealable push-pull closure moveable between a closed position that substantially seals the container and a dispensing position that enables dispensing of the liquid contents through the closure, the closure consisting of a single component that comprises:
- a circumferential, tubular skirt including a circumferential skirt bead extending inwardly on an inner surface thereof that slidably engages the container neck;
- a top member including a peripheral lower portion and a sipper spout, the lower portion defining an upper edge of a portion of the skirt, the sipper spout extending upwardly from the lower portion and including dispensing apertures separated by bridges, the apertures and bridges forming a segment of a circular shape, an uppermost rim of at least one of the apertures is entirely disposed at an elevation above the lower portion of the top member;
- and
- a plug depending downwardly from the top member, the plug engaging the container neck to form a seal therewith while the closure is in the closed position and spaced apart from the container neck while the closure is in the dispensing position to enable the liquid contents to flow therebetween.
