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.
Claims36
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 substantially circular top member;
- a circumferential skirt extending downwardly from the top member and integrally formed therewith, the skirt having a circumferential skirt bead extending inwardly on an inner surface thereof that slidably engages the container neck;
- a sipper spout extending upwardly from the top member, the sipper spout comprising a sipper surface which is concave in a direction parallel to an axis of the closure capable of receiving a user's lip and at least one dispensing aperture formed in the sipper spout for dispensing the liquid;
- 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.
A re-sealable push-pull closure for use with a container having a neck for slidably mounting the closure thereon, the closure consisting of a single component that comprises:
- a substantially circular top member;
- a circumferential skirt extending downwardly from the top member and integrally formed therewith, the skirt having a circumferential skirt bead extending inwardly on an inner surface thereof;
- a sipper spout extending upwardly from the top member, the sipper spout comprising a substantially smoothly curved sipper surface which is concave in a direction parallel to an axis of the closure capable of receiving a user's lip, at least one dispensing aperture formed in the sipper spout, and an arcuate sidewall extending upwardly from the skirt, the sipper surface defined on a side thereof by a chord of an arc defined by the skirt and extending outwardly and upwardly toward the at least one aperture in constant curvature in longitudinal cross section;
- and
- a substantially circular plug depending downwardly from the top member.
The container assembly 22 wherein the spout sidewall has a radially inward taper.
