Abstract

A child-resistant compact for dispensing product on blister cards includes a first portion having a first panel hinged to a first clamp for capturing an end of a first blister card, and a second portion having a second panel hinged to a second clamp for capturing an end of a second blister card. The first and second clamps are connected to each other such that the first and second panels form a chamber for enclosing the blister cards. At least one child-resistant latch is on the periphery of the panels for opening one or both panels with respect to the clamps for access to the blister cards.

Claims

1. A child-resistant compact for dispensing product on blister cards, which includes:

a first portion having a first panel hinged to a first clamp for capturing an end of a first blister card, a base wall, sidewalls extending along the base wall, and an endwall extending between said sidewalls,

a second portion having a second panel hinged to a second clamp for capturing an end of a second blister card,

means connecting said first and second clamps to each other such that said first and second panels form a closable cavity for enclosing the blister cards,

at least one child-resistant latch on peripheries of said first and second panels for opening one or both of said panels with respect to said clamps for access to blister cards captured by said clamps, wherein said at least one child-resistant latch includes a first latch opposite said clamps including a latch arm extending from said base wall of said first portion and disposed in a gap in said end wall;

a reinforcing wall integral with said base wall and said end wall and spaced from said end wall adjacent to said latch arm to strengthen said first panel against bending upon activation of said latch arm; and

at least one reinforcing rib extending between said latch arm and said reinforcing wall to strengthen said latch arm.

2. The compact set forth in claim 1 wherein said first portion and said second portion are of separate molded plastic constructions.

3. The compact set forth in claim 1 wherein said first portion and said second portion together are of one-piece integrally molded plastic construction, said means comprising a hinge integrally connecting said first and second clamps.

4. The compact set forth in claim 1 further comprising a guide adjacent to said latch for aligning said panels as said panels are closed toward each other, wherein said guide includes at least one guide post on said second panel for receipt between said end wall and said reinforcing wall of said first panel to promote engagement of said latch.

5. The compact set forth in claim 4 wherein said at least one guide post includes an angled free end so that engagement between said at least one guide post and at least one of said end wall or said reinforcing wall cams said panels into alignment.

6. The compact set forth in claim 5 including a pair of said guide posts on one of said panels on opposite sides of said latch.

7. The compact set forth in claim 1 wherein said at least one child resistant latch includes second latches disposed on opposite sides of said first and second panels.

8. The compact set forth in claim 7 wherein said second latches include latch arms on said first panel extending from said base wall through associated recesses in said sidewalls and having outwardly convex wall portions depressible to release said latch arms, and latch apertures in said sidewalls and at least partially defined by sections of said sidewalls having cam surfaces for engagement by said latch arms to cam said latch arms inwardly until said outwardly convex wall portions of said latch arms snap into said apertures when said panels are fully closed.

9. The compact set forth in claim 8 wherein said outwardly convex wall portions have rounded outer surfaces for engagement with said cam surfaces.

10. The compact set forth in claim 9 wherein said first panel includes a reinforcing wall adjacent to each latch arm of said second latches to strengthen said first panel against bending upon activation of said second latches.

11. The compact set forth in claim 10 including at least one reinforcing rib extending between each said latch arm of said second latches and the adjacent reinforcing wall.

12. A child-resistant compact for dispensing product on blister cards, which includes:

a first portion having a first panel hinged to a first clamp for capturing an end of a first blister card,

a second portion having a second panel hinged to a second clamp for capturing an end of a second blister card,

means connecting said first and second clamps to each other such that said first and second panels form a closable cavity for enclosing the blister cards, and

at least one child-resistant latch on peripheries of said first and second panels for opening one or both of said panels with respect to said clamps for access to blister cards captured by said clamps,

wherein said first clamp includes a first pair of parallel clamp members molded integrally with said first panel and interconnected by a hinge to said first panel, and wherein said second clamp includes a second pair of parallel clamp members molded integrally with said second panel and interconnected by a hinge to said second panel, said first and second pairs of parallel clamp members including first clamp members integrally joined to said first and second panels by said hinges and second clamp members integrally joined to said first clamp members by hinges, said first and second clamp members each including cooperating clamp elements to capture said blister cards.

13. The compact set forth in claim 12 wherein said first and second portions are of separate molded plastic constructions, and wherein said means includes connectors on said first and second clamps connecting said first and second clamps to each other.

14. The compact set forth in claim 12 wherein said first portion and said second portion together are of one-piece integrally molded plastic construction, said means comprising a hinge integrally connecting said first and second clamps.
