Abstract

An apparatus for removing a safety cap from a safety container is provided for a prescription bottle or other safety container system. A tapered surface wedgingly engages the periphery of the safety cap when pressed into pressure engagement with the tapered surface. The tapered surface includes prongs for guiding the safety cap into pressure engagement with the tapered surface. A suction cup is disposed on the tapered surface for detaching the safety cap from the safety container.

Claims

1. For a container system comprising a safety container and a safety cap, an apparatus for releasing the safety cap from the safety container, the apparatus comprising:

means defining a cone-shaped surface, the means including a plurality of circumferentially disposed hemispherical members for wedgingly engaging the outer periphery of the safety cap, thereby providing resistance to rotation of the safety cap when the safety cap is pressed into pressure engagement with the hemispherical members and the safety container is rotated.

2. The apparatus of claim 1, wherein the spaced hemispherical members are equidistant from a center point on the cone-shaped surface.

3. The apparatus of claim 1, wherein the spaced hemispherical members are positioned symmetrically about a center point on the cone-shaped surface.

4. The apparatus of claim 1, wherein the spaced hemispherical members are arranged to form a plurality of concentric rings.

5. The apparatus of claim 1, wherein the spaced hemispherical members comprise screw heads.

6. The apparatus of claim 5, wherein the spaced hemispherical members comprise three screw heads.

7. The apparatus of claim 1, wherein the means defining a cone-shaped surface further comprises a groove disposed on one of the hemispherical members.

8. The apparatus of claim 1, wherein the means defining a cone-shaped surface further comprises a groove disposed on each of the hemispherical members.

9. The apparatus of claim 1, including means for detaching the safety cap from the safety container.

10. The apparatus of claim 9, wherein the detaching means is a suction cup.

11. The apparatus of claim 10, including means for outwardly biasing the suction cup away from the cone-shaped surface.

12. The apparatus of claim 9, wherein the detaching means is a shelf defined by at least one semicircular ridge.

13. The apparatus of claim 1, including elongated means for guiding the safety cap into pressure engagement with the means defining a cone-shaped surface.

14. The apparatus of claim 13, wherein the elongated means comprises prongs which further define the cone-shaped surface.

15. For a container system comprising a safety container and a safety cap, an apparatus for releasing the safety cap from the safety container, the apparatus comprising:

a plurality of spaced hemispherical members positioned as to define a cone-shaped surface for accepting a safety cap, the hemispherical members comprising a groove for wedgingly engaging an outer periphery of the safety cap and for providing resistance to rotation of the safety cap when pressed into pressure engagement with the plurality of hemispherical members.

16. For a container system comprising a safety container and a safety cap, a method for releasing the safety cap from the safety container, the method comprising the steps of:

providing a plurality of hemispherical members defining a cone-shaped surface for accepting a safety cap for applying resistance to rotation of the safety cap;

guiding the safety cap into engagement with the plurality of hemispherical members;

pressing the safety container into pressure engagement with the plurality of hemispherical members; and

rotating the safety container.

17. The method of claim 16, wherein means defining a cone-shaped surface further comprises a groove disposed on the textured elements.

18. A method of claim 16, further comprising the step of:

detaching the safety cap from the safety container.
