Child-resistant closure and package

Abstract

A child-resistant closure includes a polymeric top portion, a polymeric annular portion and a slidable lid. The polymeric top portion has an exterior surface. The polymeric top portion further includes a slide portal with a retention wall and at least one depression formed in a top surface thereof. The slide portal forms an aperture. The skirt portion depends from the polymeric top portion. The slidable lid includes at least one spring-retention mechanism and a retention projection extending from the slidable lid. The spring-retention mechanism is configured to be located in the depression when the closure is in a closed position. The slidable lid is configured to slide along the slide portal. The retention projection in conjunction with the retention wall assists in inhibiting removal of the slidable lid from the remainder of the closure.

         4 . The closure of  claim 1 , wherein the retention wall and the top surface of the slide portal assist in forming an opening to allow the slidable lid to move therethrough. 
     
     
         5 . The closure of  claim 4 , wherein the opening formed by the retention wall and the top surface of the slide portal is generally C-shaped. 
     
     
         6 . The closure of  claim 1 , wherein the slide portal is integrally formed with the polymeric annular skirt portion and a remainder of the polymeric top portion. 
     
     
         7 . The closure of  claim 1 , wherein the slide portal is a polymeric slide portal. 
     
     
         8 . The closure of  claim 1 , wherein the slidable lid further includes a gripping projection extending from a top surface thereof, the gripping projection is configured to assist in the sliding of the slidable lid along the slide portal. 
     
     
         9 . The closure of  claim 8 , wherein the slidable lid includes a pusher tab, the pusher tab located at a first end and the gripping projection is located at a second end, the first and second ends being located opposite of each other. 
     
     
         10 . The closure of  claim 1 , wherein an audible sound occurs when the at least one spring-retention mechanism is located within the at least one depression. 
     
     
         11 . The closure of  claim 1 , wherein the at least one spring-retention mechanism and the at least one depression secure the child-resistant closure in the closed position. 
     
     
         12 . The closure of  claim 8 , wherein the gripping projection is a generally rectangular-walled structure. 
     
     
         13 . A package comprising:
 a container having a neck portion defining an opening, the neck portion having an exterior surface and an interior surface; and   a closure being configured for fitment to the neck portion of the container for closing the opening, the closure including a polymeric top portion, a polymeric annular skirt portion and a slide portal, the polymeric top portion having an exterior surface and an interior surface, the slide portal including a retention wall and at least one depression formed in a top surface of the slide portal, the slide portal forming an aperture, the polymeric annular skirt portion depending from the polymeric top portion, the slidable lid including at least one spring-retention mechanism and a retention projection extending from the slidable lid, the at least one spring-retention mechanism configured to be located in the at least one depression when the closure is in a closed position, the at least one spring-retention mechanism being located inwardly from the polymeric annular skirt when the closure is in the closed position, the at least one spring-retention mechanism extending outwardly from the polymeric annular skirt when the closure is in an open position, the slidable lid being configured to slide along the slide portal, the retention projection in conjunction with the retention wall assists in inhibiting removal of the slidable lid from the remainder of the closure.   
     
     
         14 . The package of  claim 13 , wherein the container has an external thread formation on the neck portion. 
     
     
         15 . The package of  claim 13 , wherein the at least one spring-retention mechanism is a plurality of spring-retention mechanisms, and wherein the at least one depression is a plurality of depressions. 
     
     
         16 . The package of  claim 13 , wherein the retention wall includes a pair of sidewalls bridging a top wall, the top wall having a downwardly extending retention tab, the retention wall and the top surface of the slide portal assist in forming an opening to allow the slidable lid to move therethrough. 
     
     
         17 . The package of  claim 16 , wherein the opening formed by the retention wall and the top surface of the slide portal is generally C-shaped.
