Abstract
A closure includes a pivoting closure cap and a closure base configured to more easily align and securely pivot open without uncoupling. In various embodiments, the pivoting closure cap includes a pair of hinge assemblies including hinge pins pivotable between a closed position and an open position where the pivoting closure cap is opened for pouring. The closure base includes a pair of hinge pin receivers with a hinge pin sockets. The hinge pins located and rotatable within the sockets.
Claims20
A closure comprising:
- a pivoting closure cap comprising an upper surface and a lower surface;
- a hinge assembly extending downward from the pivoting closure cap, the hinge assembly comprising:
- a support member extending between a top end connected to the cap and a bottom end;
- a truncated hinge pin coupled to the support member at the bottom end;
- and
- a detent rib extending upwardly from the pin toward the top end;
- and
- a closure base comprising:
- a hinge pin receiver having a receiver top and a receiver bottom, the hinge pin receiver comprising:
- an elongated hinge pin socket formed in the receiver proximate the receiver bottom;
- a detent groove extending from the pin socket toward the receiver top, the hinge pin being positioned and rotatable within the socket;
- and
- a cam surface located at the receiver bottom and adjacent to the socket, the bottom end of the hinge assembly bearing against the cam surface such that when the closure cap is pivoted open, the closure cap is simultaneously lifted during pivoting.

A closure comprising:
- a pivoting closure cap including an upper surface and a lower surface;
- a pair of hinge assemblies extending downward from opposing sides of the pivoting closure cap and having the same rotational axis, each hinge assembly comprising:
- a support member including a top end connected to the cap and extending to a bottom end;
- a truncated hinge pin extending outward from the support member at the bottom end;
- and
- a detent rib extending upwardly from the hinge pin toward the top end;
- and
- a closure base comprising:
- an opposing pair of hinge pin receivers, each hinge pin receiver including a receiver top and a receiver bottom, each hinge pin receiver comprising:
- a hinge pin socket extending through an inner wall of the closure base and formed in the receiver proximate the receiver bottom;
- and
- a detent groove extending toward the receiver top, the hinge pins being positioned and rotatable within the sockets.
