Child-resistant vial
The possibility that a child inadvertently unlocks a child-resistant vial by triggering the latch with his teeth is avoided by preventing access to the latch from under the cap. This is achieved by covering all sides of the latch with the exception of the front face thereof intended to be used to trigger the latch while the cap is lifted. Improvement of the humidity barrier in such a vial is achieved by closing the vial container with a cap including a recess that defines inner and outer peripheral walls in the cap. The inner and outer walls together define an annular gap that is configured to complementary receive the peripheral flange of the container. Both the edge of the inner wall of the cap and the inner peripheral wall of the container are provided with sealing rings that are axially distanced when the cap closes the vial container.
1. A child-resistant vial comprising:
a container having a first peripheral skirt provided with an edge that includes a peripheral flange;
a cap pivotally mounted to the container via a hinge that is integral to both the cap and container,
the container being closable by pivoting the cap onto the container,
the cap having a second peripheral skirt that generally overlays the first peripheral skirt in a complementary fashion when the container is closed by the cap,
the second skirt having an edge that abuts the peripheral flange of the first skirt when the container is closed by the cap so as to close access to the edge of the second skirt;
a first latching element in the form of a tab that protrudes from the first skirt generally parallel thereto and that has a free distal end;
a second latching element, in the form of a cut out portion in the second skirt, that cooperates with the tab to lock the vial when the container is closed by the cap,
when the vial is locked, the tab is prevented from being released from the cut out portion unless simultaneous pressing on the tab and pulling on the cap; and
a tab guard on the first skirt, that closes access to the free end of the tab when the container is closed by the cap.
2. The child-resistant vial of claim 1 , wherein the tab includes a cut defining a shoulder at a bottom edge of the tab, the cut out portion being configured so as to be hooked by the shoulder when the container is closed by the cap; and
wherein the simultaneous pressing on the tab and pulling on the cap causes the cut out to be unhooked from the shoulder.
3. The child-resistant vial of claim 2 , wherein a portion of the tab below the shoulder is covered by a portion of the second skirt below the cut out.
4. The child-resistant vial of claim 1 , wherein the tab is defined by a cut in the first skirt.
5. The child-resistant vial of claim 4 , wherein the tab guard is defined by a portion of the first skirt under the cut.
6. The child-resistant vial of claim 1 , wherein the cap includes a recess.
7. The child-resistant vial of claim 6 , wherein the recess defines internal and external walls of the cap, yielding a gap therebetween that is configured to receive an upper portion of the first skirt therein.
8. The child-resistant vial of claim 7 , wherein at least one of an inner wall of the container and an inner wall of the internal wall of the cap includes a sealing ring.
9. The child-resistant vial of claim 7 , wherein each of an inner wall of the container and an inner wall of the internal wall of the cap includes a sealing ring.
10. The child-resistant vial of claim 9 , wherein both sealing rings are adjacent when the container is closed by the cap.
11. The child-resistant vial of claim 6 , wherein the recess includes a receiving portion for an identification element.
12. The child-resistant vial of claim 11 , wherein the identification element is a token or a sticker.
13. The child-resistant vial of claim 1 , wherein the tab is attached to an upper edge of the first skirt.
14. The child-resistant vial of claim 1 , wherein the tab includes a finger-receiving recess on a front face thereof.
15. The child-resistant vial of claim 1 , wherein the second skirt includes at least one of i) an embossed finger-receiving portion and ii) a finger receiving protrusion.
16. The child-resistant vial of claim 15 , wherein the second skirt includes two adjacent pairs of the embossed finger-receiving portion and the finger receiving protrusion.
17. The child-resistant vial of claim 1 , wherein the first and second skirts extend downwardly respectively from the container and the cap.
18. The child-resistant vial of claim 17 , wherein the first and second skirts both have a length that increases from the hinge to the first and second latching elements.
19. The child-resistant vial of claim 1 , wherein both the tab and the cut out portion are trapezoid-shaped.
20. The child-resistant vial of claim 1 , wherein the vial is a one-piece body made of a polymeric material.
21. The child-resistant vial of claim 1 , wherein the tab is removable to convert the vial from child-resistant to easy opening.
22. A child-resistant vial comprising:
a container having a first peripheral skirt provided with an edge that includes a peripheral flange;
a cap pivotally mounted to the container via a hinge that is integral to both the cap and container,
the container being closable by pivoting the cap onto the container,
the cap having a second peripheral skirt that generally overlays the first peripheral skirt in a complementary fashion when the container is closed by the cap,
the second skirt having an edge that abuts the peripheral flange of the first skirt when the container is closed by the cap so as to prevent access to the edge of the second skirt,
the cap having a recess defining internal and external walls of the cap, yielding a gap therebetween that receives an upper portion of the first skirt therein,
each of an inner wall of the container and an inner wall of the internal wall of the cap including a sealing ring;
a first latching element in the form of a tab that protrudes from the first skirt generally parallel thereto and that has a free distal end;
a second latching element in the form of a cut out portion in the second skirt, that cooperates with the tab to lock the vial when the container is closed by the cap,
when the vial is locked, the tab is prevented from being released from the cut out portion unless simultaneous pressing on the tab and pulling on the cap; and
a tab guard on the first skirt, that prevents access to the free end of the tab when the container is closed by the cap.
23. The child-resistant vial of claim 22 , wherein the recess includes an identification element receiving portion.
