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 including an upper surface and a lower surface;
- a hinge assembly extending downward from the pivoting closure cap including a support member including a top end connected to the cap and extending to a bottom end, a truncated hinge pin extending generally perpendicular to and from the lower end of the support member to a distal end and a detent rib extending upwardly from the pin toward the top end;
- and
- a closure base including a hinge pin receiver having a receiver top and a receiver bottom, the receiver including an elongated hinge pin socket formed in the receiver proximate the receiver bottom and a detent groove extending from the pin socket toward the receiver top, the hinge pin being located and rotatable within the socket;
- wherein the closure cap pivots relative to the closure base between a closed position in which the detent rib rests within the detent groove and an open position in which the detent rib rests outside of the detent groove.

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 including a support member including a top end connected to the cap and extending to a bottom end, a truncated hinge pin extending generally perpendicular to and from the lower end of the support member to a distal end and a detent rib extending upwardly from the pin toward the top end;
- and
- a closure base including an opposing pair of hinge pin receivers each having a receiver top and a receiver bottom, each receiver including an elongated hinge pin socket formed in the receiver proximate the receiver bottom and a detent groove extending from the pin socket toward the receiver top, the hinge pins being located and rotatable within the sockets;
- wherein the closure cap pivots relative to the closure base between a closed position in which the detent ribs rest within the detent grooves and an open position in which the detent ribs rest outside of the detent grooves.

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 including a support member including a top end connected to the cap and extending to a bottom end, a truncated hinge pin extending generally perpendicular to and from the lower end of the support member to a distal end and a detent rib extending upwardly from the pin toward the top end;
- a cylindrical cap plug extending downward from the lower surface of the pivoting closure cap;
- a closure base including an opposing pair of hinge pin receivers each having a receiver top and a receiver bottom, each receiver including an elongated hinge pin socket formed in the receiver proximate the receiver bottom and a detent groove extending from the pin socket toward the receiver top, the hinge pins being located and rotatable within the sockets,the closure base defining afluid channel positioned such that the cylindrical cap plug rests within the fluid channel when the closure is in a closed position;
- and
- a pour spout formed in the closure base, the pour spout positioned at least partially around and extending upward from the fluid channel;
- wherein the closure cap pivots relative to the closure base between the closed position in which the detent ribs rest within the detent grooves and an open position in which the detent ribs rest outside of the detent grooves;
- wherein the pair of hinge pin receiver further include a pair of cam surfaces located at the receiver bottom and adjacent to the hinge pin sockets, the bottom end of the hinge assemblies bearing against the cam surfaces such that when the closure cap is pivoted open, the closure cap is simultaneously lifted during pivoting;
- wherein the lift provided to the closure cap during pivoting lifts the cylindrical cap plug out of the fluid channel when the closure is in an open position such that a fluid can travel through the fluid channel and pour from the spout.
