Abstract

A cap including a cap body and a spout hingedly connected to the cap body and moveable relative to the cap body between at least a first position and a second position, wherein the spout in magnetically biased to the first position.

First claim

What is claimed is:

1. A cap comprising:
a cap body;
a spout hingedly connected to said cap body about a hinge axis and rotationally moveable relative to said cap body between at least a closed position and an opened position;
a first magnet connected to a portion of said cap body; and
a second magnet connected to said spout at a portion thereof that rotates about said hinge axis towards and away from said portion of said cap body connected to said first magnet,
wherein said spout is magnetically biased to said closed position.

2. The cap of claim 1 wherein said first magnet and said second magnet form an attracting pair.

3. The cap of claim 2 wherein at least one of said first magnet and said second magnet comprises a rare-earth magnet.

4. The cap of claim 2 further comprising a third magnet connected to said cap body and a fourth magnet connected to said spout, wherein said third magnet and said fourth magnet form a repelling pair.

5. The cap of claim 4 wherein at least one of said third magnet and said fourth magnet comprises a rare-earth magnet.

6. The cap of claim 4 wherein said spout comprises a spout body and an extension member extending from said spout body.

7. The cap of claim 6 wherein said second magnet is connected to said spout body and said fourth magnet is connected to said extension member.

8. The cap of claim 4 wherein said first magnet and said third magnet are embedded in said cap body, and wherein said second magnet and said fourth magnet are embedded in said spout.

9. The cap of claim 1 wherein said cap body comprises a lid portion that defines a fluid port.

10. The cap of claim 9 wherein said spout defines a fluid channel, and wherein said fluid channel is fluidly decoupled from said fluid port when said spout is in said opened position and fluidly coupled with said fluid port when said spout is in said closed position.

11. The cap of claim 9 wherein said lid portion further defines a recess, and wherein said spout is at least partially received in said recess when said spout is in said first position.

12. The cap of claim 9 wherein said cap body further comprises a barrel portion extending from said lid portion, said barrel portion comprising a coupling feature.

13. The cap of claim 12 wherein said coupling feature comprises internal threads.

14. The cap of claim 1 wherein at least one of said cap body and said spout comprises a polymeric material.

15. A container assembly comprising:
a container comprising a container body defining an internal volume and a neck defining an opening into said internal volume; and
said cap of claim 1 , in which said cap body is in engagement with said neck.

16. The container assembly of claim 15 wherein said engagement between said cap body and said neck is a threaded engagement.

17. A cap comprising:
a cap body comprising a lid portion and a barrel portion extending from said lid portion, said lid portion defining a fluid port;
a spout comprising a spout body including a proximal end portion and a distal end portion and defining a fluid channel extending from the proximal end portion to the distal end portion, said spout body being hingedly connected to said lid portion along a hinge axis disposed between the proximal end and the distal end of the fluid channel, said spout body being rotationally moveable relative to said lid portion between at least a closed position, wherein said fluid channel is fluidly decoupled from said fluid port, and an opened position, wherein said fluid channel is fluidly coupled with said fluid port; and
an attracting pair of magnets magnetically biasing said spout body to said closed position, wherein a first magnet of said attracting pair of magnets is connected to said lid portion and a second magnet of said attracting pair of magnets is connected to said spout body at a portion thereof that rotates about said hinge axis towards and away from said lid portion.

18. The cap of claim 17 wherein said spout further comprises an extension member extending from said spout body.

19. The cap of claim 18 further comprising a repelling pair of magnets, wherein a first magnet of said repelling pair of magnets is connected to said lid portion and a second magnet of said repelling pair of magnets is connected to said extension member.

20. The cap of claim 18 wherein said extension member extends from said spout body in a radial direction with respect to said hinge axis.
