Child-resistant flip-top dispensing closure and package
View Patent ↗A child-resistant dispensing closure includes a base having a deck with a dispensing opening and a peripheral skirt. A lid is integrally molded with the base and coupled by a hinge to a periphery of the base so as to be pivotable between closed and open positions. One of the base and the lid has a latch arm resiliently extending from its periphery diametrically opposite the hinge. The latch arm has a pair of oppositely extending tabs adjacent to a free end of the arm. The other of the base and the lid has an axial passage for receiving the latch arm, and a pair of laterally spaced ledges in the passage for engagement by the tabs to lock the lid in the closed position. The latch arm is directly manually engageable by a user from a radial direction external to the closure to pivot the latch arm radially inwardly within the passage and release the tabs from the ledges so that the lid can be pivoted to the open position.

11. The package set forth in claim 10 wherein said ledges in said passage radially open at said skirt such that said latch arm may extend outside of said skirt as said lid is moved toward said closed position and then snap radially inwardly beneath said ledges due to resilience of said latch arm and connection between said latch arm and said lid.
12. The package set forth in claim 11 further comprising cam surfaces on said ledges adjacent to said open passage in said skirt for engagement by said tabs on said latch arm to cam said latch arm radially outwardly as said lid is pivoted toward said closed position.

14. The package set forth in claim 10 further comprising cam surfaces on said ledges, said tabs on said latch arm, or both, for flexing said resilient latch arm to snap said tabs over said ledges as said lid is pivoted toward said closed position.
15. A child-resistant closure and container package that includes:
a container and a closure secured to said container,
said closure comprising:
