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 closure for forming a child-resistant package when combined with a container, the closure comprising:
a cover;
a skirt depending downwardly from the cover adjacent an outer periphery of the cover, wherein the outer periphery is radially outward of a center of the skirt in a radial direction;
a skirt thread disposed on an inner surface of the skirt and configured to releasably engage a thread of the container;
a key coupled to the 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;
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;
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; and
wherein the at least one flexible member includes at least two key arms interposed between the key and the skirt of the closure.

2. The closure of claim 1 , wherein the key connects to at least one of the skirt of the closure, and the cover of the closure 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.

3. The closure of claim 1 , wherein the at least one flexible member is a key body interposed between the key grip and the cover.

4. The closure of claim 1 , wherein the at least one flexible member includes a flexible area in the cover comprising an elastomeric spring-like member.

5. The closure of claim 4 , wherein the at least one flexible member includes thermoplastic elastomer (TPE).

6. The closure of claim 1 , wherein at least a portion of the key grip extends radially outwardly farther than the key in the radial direction.

7. A closure for forming a child-resistant package when combined with a container, the closure comprising:
a cover, a skirt, and a key wherein the key is located radially outward of the skirt in a radial direction;
wherein the key is coupled to the skirt and is 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 skirt having an internal thread 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 a key protrusion of the key;
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;
at least one flexing member interposed between the key and the skirt that accommodates movement when subject to the first user input between the locked position and the unlocked position, wherein the at least one 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;
wherein the at least one flexing member includes at least two key arms coupling the key and the skirt, wherein the at least two key arms extend downwardly in the vertical direction and outwardly in the radial direction from the skirt to the key.

8. The package of claim 7 , wherein the at least one flexing member couples the key grip and the skirt.

9. The closure of claim 7 , wherein the at least two key arms extend toward each other as they extend from the skirt to the key in a third direction that is transverse to the radial direction and the vertical direction.

10. The package of claim 7 , wherein at least a portion of the key grip extends radially outwardly farther than the skirt in the radial direction.

11. A closure for forming a child-resistant package when combined with a container, the closure comprising:
a cover;
a skirt depending downwardly from the cover adjacent an outer periphery of the cover, wherein the outer periphery is radially outward of a center of the skirt in a radial direction;
a skirt thread disposed on an inner surface of the skirt and configured to releasably engage a thread of the container;
a key coupled to the 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;
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; and
wherein at least a portion of the key grip extends radially outwardly farther than the key in the radial direction.

12. The closure of claim 11 , 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.

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