Selectively openable closure for a container
A closure for a container, and more specifically a closure that is selectively openable and/or lockable providing, for example, one or more child resistant opening features is disclosed.
1. A package, comprising:
a container defining a product storage region; and
a closure having a base and a lid;
wherein the base is coupled to the container and the lid is movable relative to the base between a closed position and an open position;
a locking protrusion on the base that extends in a radial direction from the base;
a collar coupled to the lid and having a side wall that is movable between a locked position, in which it prevents the lid from opening, and an unlocked position in which it allows the lid to open; and
a collar base bead extending in a radial direction from the collar side wall;
wherein the locking protrusion on the base and the collar base bead are in vertical alignment to prevent opening of the lid when the lid is in the closed position and the collar is in the locked position;
wherein the collar is configured to be moved from the locked position to the unlocked position by a first user input, with the collar base bead out of vertical alignment with the locking protrusion to allow opening of the lid; and
wherein the lid is movable from the closed position to the open position by a second user input;
wherein the collar includes a hub and at least one spoke, wherein the hub is prevented from rotating relative to the lid, the collar is allowed to rotate relative to the lid, and the at least one spoke is deformable from a resting condition when the collar is in the locked position to a deformed condition when the collar is in the unlocked position.
2. The package of claim 1 , wherein the lid is rotatable relative to the base about a hinge.
3. The package of claim 1 , wherein the collar is attached to the lid by at least one of cooperating beads and lips to allow the collar to rotate relative to the lid and to substantially prevent vertical motion of the collar relative to the lid.
4. The package of claim 1 , wherein the base includes a skirt, a shoulder, and a rim, wherein the rim is disposed at the top of the base and defines an opening through the base, the shoulder is disposed below the rim, and the skirt is disposed below the shoulder, wherein the skirt extends radially outwardly farther than the shoulder.
5. The package of claim 1 , wherein the base is permanently attached to the container.
6. The package of claim 5 , wherein the base is permanently attached to the container by a snap fit.
7. The package of claim 1 , wherein the collar includes a hinge recess.
8. The package of claim 1 , wherein the hub is prevented from rotating relative to the lid by the engagement of at least one of a collar attachment portion and a lid attachment portion.
9. The package of claim 1 , wherein the at least one spoke includes a center component formed of a first material and an outer component formed of a second material.
10. The package of claim 9 , wherein the center component is formed of substantially the same material as the hub and the collar side wall and the outer component is formed of a different material.
11. The package of claim 10 , wherein the outer component is formed of a thermoplastic elastomer (TPE).
12. The package of claim 11 , wherein the collar is formed by first molding the hub, spoke center component, and side wall, and subsequently overmolding the outer component onto the center component.
13. The package of claim 1 , wherein a plurality of locking protrusions are circumferentially separated by at least one unlocking slot, wherein the collar base bead is aligned with the at least one unlocking slot and configured to pass vertically through the at least one unlocking slot when the collar is in the unlocked position to allow opening of the lid relative to the base.
14. A closure and collar for a container, comprising:
a base and a lid;
wherein the lid is movable relative to the base between a closed position and an open position;
a locking protrusion on the base that extends in a radial direction from the base;
a collar coupled to the lid and having a side wall that is movable between a locked position, in which it prevents the lid from opening, and an unlocked position in which it allows the lid to open; and
a collar base bead extending in a radial direction from the collar side wall;
wherein the locking protrusion on the base and the collar base bead are in vertical alignment to prevent opening of the lid when the lid is in the closed position and the collar is in the locked position;
wherein the collar is configured to be moved from the locked position to the unlocked position by a first user input, with the collar base bead out of vertical alignment with the locking protrusion to allow opening of the lid; and
wherein the lid is movable from the closed position to the open position by a second user input;
wherein the collar includes a hub and at least one spoke, wherein the hub is prevented from rotating relative to the lid, the collar is allowed to rotate relative to the lid, and the at least one spoke is deformable from a resting condition when the collar is in the locked position to a deformed condition when the collar is in the unlocked position.
15. The closure and collar of claim 14 , wherein the hub is prevented from rotating relative to the lid by the engagement of at least one of a collar attachment portion and a lid attachment portion.
16. The closure and collar of claim 14 , wherein the at least one spoke includes a center component formed of a first material and an outer component formed of a second material.
17. The closure and collar of claim 14 , wherein the base includes a skirt, a shoulder, and a rim, wherein the rim is disposed at the top of the base and defines an opening through the base, the shoulder is disposed below the rim, and the skirt is disposed below the shoulder, wherein the skirt extends radially outwardly farther than the shoulder.
18. A package, comprising:
a container defining a product storage region; and
a closure having a base and a lid;
wherein the base is coupled to the container and the lid is movable relative to the base between a closed position and an open position; and
a collar having a side wall that is movable between a locked position, in which it prevents a user from opening the lid, and an unlocked position in which it allows the user to open the lid; and
wherein the collar is rotatable relative to the base by a user input to move the collar between the locked position and the unlocked position;
wherein the collar includes a hub and at least one spoke, wherein the hub is prevented from rotating relative to the lid, the collar is allowed to rotate relative to the lid, and the at least one spoke is deformable from a resting condition when the collar is in the locked position to a deformed condition when the collar is in the unlocked position.
19. The package of claim 18 , wherein the hub is prevented from rotating relative to the lid by the engagement of at least one of a collar attachment portion and a lid attachment portion.
20. The package of claim 18 , wherein the at least one spoke includes a center component formed of a first material and an outer component formed of a second material.
