Reversible child resistant cap and combination of a container and a reversible child resistant cap
View Patent ↗The present invention relates to a reversible child resistant cap and a closure system having two positions, the first being a child resistant position and the other being a non-child resistant position. The cap is characterized in that it has a closure plane, a circumferential outer skirt for engaging a container, and a circumferential resilient depending inner member.
1. A reversible child resistant cap for use with a container, the cap having a child resistant mode when applied to the container in a first child resistant position and having a non-child resistant mode when applied to the container in a second non-child resistant position, the cap comprising:
a closure plane;
a circumferential outer skirt comprising an upper portion extending in an upward direction from the closure plane, a lower portion extending in a downward direction from the closure plane;
a circumferential inner skirt inside the circumferential outer skirt, the circumferential inner skirt having a circumferential upper end and a circumferential lower end, the circumferential upper end being inside the upper portion of the circumferential outer skirt and extending in an upward direction from the closure plane and the circumferential lower end being inside the lower portion of the circumferential outer skirt and extending in a downward direction from the closure plane;
a non-child resistant engaging closure means for engaging the container and positioned above and spaced from the closure plane; and
a child resistant engaging closure means for engaging the container and positioned below and spaced from the closure plane.
2. The cap in accordance with claim 1 , wherein:
the upper portion of the circumferential outer skirt includes an upper end; and
the upper end of the circumferential inner skirt is positioned at substantially the same distance from the closure plane as the upper end of the circumferential outer skirt.
3. The cap in accordance with claim 1 , wherein the circumferential upper end of the circumferential inner skirt is closed and the circumferential lower end of the circumferential inner skirt is open.
4. The cap in accordance with claim 1 , further comprising:
the upper portion of the circumferential outer skirt including an inner surface; and
an annular gap between the circumferential upper end of the circumferential inner skirt and the inner surface of the upper portion of the circumferential outer skirt.
5. The cap in accordance with claim 1 , wherein the upper portion of the outer skirt comprises the non-child resistant engaging means.
6. A reversible child resistant cap for use with a container having an opening, the cap having a child resistant mode when applied to the container in a first child resistant position and having a non-child resistant mode when applied to the container in a second non-child resistant position, the cap comprising:
a closure plane;
a circumferential outer skirt including an upper portion extending in an upward direction from the closure plane and a lower portion extending in a downward direction from the closure plane;
a circumferential depending inner member inside the circumferential outer skirt, the circumferential depending inner member having a circumferential upper end extending in an upward direction from the closure plane and a circumferential lower end extending in a downward direction from the closure plane;
a non-child resistant engaging means positioned above and spaced from the closure plane for engaging the container; and
a child resistant engaging lug positioned below and spaced from the closure plane for engaging the container.
7. The cap in accordance with claim 6 , wherein the circumferential upper end of the circumferential depending inner member plugs the opening of the container when in the second non-child resistant position.
8. The cap in accordance with claim 6 , wherein the circumferential lower end of the circumferential depending inner member plugs the opening of the container when in the first child resistant position.
9. A reversible child resistant cap for use with a container, the cap having a child resistant mode when applied to the container in a first child resistant position and having a non-child resistant mode when applied to the container in a second non-child resistant position, the cap comprising:
a closure plane;
a circumferential outer skirt comprising an upper portion extending in an upward direction from the closure plane, a lower portion extending in a downward direction from the closure plane, the upper portion including an upper end and an inner surface;
a circumferential inner skirt inside the circumferential outer skirt, the circumferential inner skirt having a closed circumferential upper end and an open circumferential lower end;
a non-child resistant engaging closure means for engaging the container and positioned above and spaced from the closure plane;
a child resistant engaging lug for engaging the container and positioned below and spaced from the closure plane;
an annular gap between the circumferential upper end of the circumferential inner skirt and the inner surface of the upper portion of the circumferential outer skirt; and
wherein the circumferential upper end of the circumferential inner skirt is positioned at substantially the same distance from the closure plane as the upper end of the circumferential outer skirt and the circumferential lower end of the circumferential inner skirt extends from the closure plane opposite the circumferential upper end of the circumferential inner skirt.
