Abstract

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.

First claim

That which is claimed:

1. A package, comprising:
a container defining a product storage region; and
a closure coupled to the container and covering the product storage region and blocking access to the product storage region when in a closed position;
wherein the closure includes a cover, an outer skirt, and an inner skirt, wherein the outer skirt and inner skirt depend downwardly from the cover and the inner skirt is disposed radially inwardly of the outer skirt;
wherein the closure includes a key, wherein the key is selectively movable relative to the closure outer skirt by a first user input between a locked position and an unlocked position;
wherein the key includes a key protrusion in alignment with a neck blocking tab coupled to a neck of the container when the key is in the locked position blocking rotation of the closure relative to the container, and wherein the key protrusion is moved out of alignment with the neck blocking tab when the key is in the unlocked position allowing rotational removal of the closure from the container by a second user input moving the closure from a closed position to an open position;
wherein the key includes a key grip configured to allow a user to provide the first user input by the key grip in a vertical direction transverse to a radial direction of the closure; and
wherein the key is movable in the vertical direction when the key is moved from the locked position to the unlocked position.

2. The package of claim 1 , wherein the key includes at least one flexible member that allows movement of the key from the locked position to the unlocked position.

3. The package of claim 2 , wherein the at least one flexible member of the key biases the key toward the locked position when in the unlocked position to provide a key that tends toward the locked position in the absence of the first user input.

4. The package of claim 3 , wherein the at least one flexible member is a key body interposed between the key grip and a closure cover.

5. The package of claim 3 , wherein the at least one flexible member is a key arm interposed between the key and an inner skirt of the closure.

6. The package of claim 3 , wherein the at least one flexible member is a flexible area comprising an elastomeric spring-like member, wherein the flexible area is at least one of included in the cover of the closure and adjacent the cover of the closure.

7. The package of claim 6 , wherein the key slides in the vertical direction relative to the outer skirt of the closure to move between the locked position and the unlocked position.

8. The package of claim 1 , wherein the key connects to at least one of the inner skirt of the closure and the outer skirt of the closure, and the cover at a hinge area, wherein the key is at least partially rotatable about the hinge area to move between the locked position and the unlocked position.

9. A closure for forming a child-resistant package when combined with a container, the closure comprising:
a cover;
an outer skirt depending downwardly from the cover adjacent an outer periphery of the cover;
an inner skirt depending downwardly from the cover and disposed radially inwardly of the outer skirt in a radial direction;
a skirt thread on an inner surface of the inner skirt configured to releasably engage a thread of the container;
a key coupled to at least one of the outer skirt and the inner skirt, wherein the key is movable by a user input from a locked position to an unlocked position;
wherein the key is moved in a vertical direction that is transverse to the radial direction when moved between the locked position and the unlocked position; and
wherein the key includes a key grip configured to allow a user to provide the user input by pushing the key grip in the vertical direction.

10. The closure of claim 9 , wherein the key connects to the at least one of the inner skirt of the closure, the outer skirt of the closure, and the cover at a hinge area, wherein the key is at least partially rotatable about the hinge area to move between the locked position and the unlocked position.

11. The closure of claim 9 , wherein the key includes at least one flexible member that allows movement of the key from the locked position to the unlocked position, wherein the at least one flexible member of the key biases the key toward the locked position when in the unlocked position to provide a key that tends toward the locked position in the absence of the first user input.

12. The closure of claim 11 , wherein the at least one flexible member is a key body interposed between the key grip and the cover.

13. The closure of claim 11 , wherein the at least one flexible member includes at least two key arms interposed between the key and the inner skirt of the closure.

14. The closure of claim 11 , wherein the at least one flexible member is a flexible area in the cover comprising an elastomeric spring-like member.

15. The closure of claim 14 , wherein the at least one flexible member includes thermoplastic elastomer (TPE).

16. The closure of claim 9 , wherein at least a portion of the key grip extends radially outwardly farther than the outer skirt.

17. A package, comprising:
a container having a floor, a side wall, and a neck, wherein the floor and side wall at least partially defining a product storage region;
a blocking tab coupled to and extending radially outwardly from the container neck;
a closure having a cover configured to block access to the product storage region when the closure is in a closed position, the closure having an inner skirt and an outer skirt, wherein the outer skirt is located outwardly of the inner skirt in a radial direction;
a key coupled to the closure and movable by a first user input in a vertical direction from a locked position to an unlocked position, wherein the vertical direction is transverse to the radial direction;
the closure inner skirt having an internal thread configured to engage an external thread of the container neck and configured to allow rotational movement by a second user input between a closed position and an open position;
wherein rotation in a direction moving the closure from the closed position to the opened position is blocked by interaction of the neck blocking tab of the container and a key protrusion of the key;
the key being coupled to at least one of the inner skirt and outer skirt;
the key extending from a key grip area configured to be actuated in the vertical direction toward the closure cover by the first user input; and
at least one flexing member that accommodates movement when subject to the first user input between the locked position and the unlocked position, wherein the flexing member is biased toward the locked position so that the key tends to return to the locked position in the absence of the first user input.

18. The package of claim 17 , wherein the flexing member is a key body.

19. The package of claim 17 , wherein the flexing member is at least one key arm coupling the key grip and at least one of the inner skirt and outer skirt.

20. The package of claim 17 , wherein at least a portion of the key grip extends radially outwardly farther than the outer skirt.
