Abstract

A child-resistant container that includes a cap and a bottle portion. The cap includes several inner engagement features protruding radially inwardly and the finish of the bottle portion includes a protrusion disposed about the opening with an overhanging ledge. Slots in the ledge correspond to the engagement features. In one particular embodiment, the cap includes two different length circumferential engagement features and two triangular engagement features.

First claim

What is claimed is:

1. A child-resistant container, comprising:
a cap including an upper surface and a wall having an interior surface, the interior surface of the wall including a first engagement feature, a second engagement feature, a third engagement feature, and a fourth engagement feature protruding radially inwardly;
a bottle portion including an outer wall and a finish having an opening into the container defined by a rim, the finish including a tapered protrusion disposed about the rim with a ledge on an underside thereof, and the tapered protrusion having gaps in the ledge including a first slot corresponding to the first engagement feature, a second slot corresponding to the second engagement feature, a third slot corresponding to the third engagement feature, and a fourth slot corresponding to the fourth engagement feature, the first, second, third, and fourth engagement features each including an upper horizontal surface;
wherein in a locked configuration, the cap is attached to the finish with the wall disposed radially outwardly around the tapered protrusion and the first, second, third, and fourth engagement features are aligned below the ledge of the tapered protrusion such that the cap is locked against removal from the finish in a vertical direction by engagement of the horizontal surfaces of the first, second, third, and fourth engagement features with the ledge;
wherein in an unlocked configuration, the first, second, third, and fourth engagement features are aligned vertically with the corresponding first, second, third, and fourth slots such that the cap can be removed from the finish vertically with the first, second, third, and fourth engagement features passing through the gaps in the ledge;
wherein the first engagement feature has a first thickness in a radial direction and a first length in a circumferential direction, the first slot having the first thickness and the first length;
wherein the second engagement feature has a second thickness in the radial direction and a second length in the circumferential direction, the first thickness being equivalent to the second thickness, and the first length being less than the second length, the second slot having the second thickness and the second length;
wherein the first engagement feature is disposed opposite the second engagement feature;
wherein the third engagement feature has a first triangular shape when viewed normal to the vertical direction, the third slot having the first triangular shape;
wherein the fourth engagement feature has a second triangular shape when viewed normal to the vertical direction, the fourth slot having the first triangular shape;
wherein the third engagement feature is disposed opposite the fourth engagement feature.

2. A child-resistant container, comprising:
a cap including a wall having an interior surface, the interior surface of the wall including a first engagement feature protruding radially inwardly, a second engagement feature on the interior surface of the cap, a third engagement feature on the interior surface of the cap, and a fourth engagement feature on the interior surface of the cap;
a bottle portion including a finish having an opening into the container, the finish including a protrusion disposed about the opening with an overhanging ledge, a first slot corresponding to the first engagement feature disposed in the ledge, a second slot disposed in the ledge corresponding to the second engagement feature, a third slot disposed in the ledge corresponding to the third engagement feature, and a fourth slot disposed in the ledge corresponding to the fourth engagement feature, wherein the protrusion includes an outer tapered surface;
wherein in a locked configuration, the cap is attached to the finish with the wall disposed radially outwardly around the finish and the first engagement feature is aligned below the ledge of the protrusion such that the cap is locked against removal from the finish in a vertical direction by engagement of the first engagement feature with the ledge, wherein in the locked configuration, the second engagement feature is aligned below the ledge of the protrusion such that the cap is locked against removal from the finish in the vertical direction by engagement of the second engagement feature with the ledge, wherein in the locked configuration, the third engagement feature is aligned below the ledge of the protrusion such that the cap is locked against removal from the finish in the vertical direction by engagement of the third engagement feature with the ledge, wherein in the locked configuration, the fourth engagement feature is aligned below the ledge of the protrusion such that the cap is locked against removal from the finish in the vertical direction by engagement of the fourth engagement feature with the ledge;
wherein in an unlocked configuration, the first engagement feature is aligned vertically with the first slot such that the cap can be removed from the finish vertically with the first engagement feature passing through the first slot in the ledge, wherein in the unlocked configuration, the second engagement feature is aligned vertically with the second slot such that the cap can be removed from the finish vertically with the second engagement feature passing through the second slot in the ledge, wherein in the unlocked configuration, the third engagement feature is aligned vertically with the third slot such that the cap can be removed from the finish vertically with the third engagement feature passing through the third slot in the ledge, wherein in the unlocked configuration, the fourth engagement feature is aligned vertically with the fourth slot such that the cap can be removed from the finish vertically with the fourth engagement feature passing through the fourth slot in the ledge;
wherein the first engagement feature has a first thickness in a radial direction and a first length in a circumferential direction, the first slot having the first thickness and the first length,
wherein the second engagement feature has a second thickness in the radial direction and a second length in the circumferential direction, the first thickness being equivalent to the second thickness, and the first length being less than the second length, the second slot having the second thickness and the second length,
wherein the third engagement feature has a first triangular shape when viewed normal to the vertical direction, the third slot having the first triangular shape.

3. The child-resistant container of claim 2 , wherein the fourth engagement feature has a second triangular shape when viewed normal to the vertical direction, the fourth slot having the first triangular shape.

4. The child-resistant container of claim 3 , wherein the first engagement feature is disposed opposite the second engagement feature.

5. The child-resistant container of claim 4 , wherein the third engagement feature is disposed opposite the fourth engagement feature.

6. The child-resistant container of claim 2 , wherein the first, second, third, and fourth engagement features each include an upper horizontal surface configured to engage with the ledge in the locked configuration.
