Child-resistant box

Abstract

A child-resistant box that includes a container and a pivotally coupled closure. The closure includes one or more projections that can engage with the rolled rim of the container for securing the closure to the container. Under an external downwards force on the closure, the one or more projections can snap over the rolled rim. The closure can be opened by depressing a front wall of the container resulting in the rim moving inwards past one or more projections. Once the rim disengages from the one or more projections, the closure can be lifted and the box opened.

What is claimed is: 
     
         1 . A child-resistant box comprising:
 a container comprising:
 a base and a wall, wherein the base and the wall define an inner volume of the container, 
 the container has an open-top, 
 an outwardly rolled rim along a periphery of the open-top; and 
   a closure pivotally coupled to the container, the closure comprising:
 a central section and a skirt that extends downwards from a periphery of the central section, 
 the skirt has an inner surface and an outer surface, the inner surface of the skirt has one or more projections, wherein a space between the one or more projections and the central section is proportional to a thickness of the outwardly rolled rim, 
 wherein the outwardly rolled rim is configured to slide over the one or more projections under an external force and retained within the space between the one or more projections and the central section. 
   
     
     
         2 . The child-resistant box according to  claim 1 , wherein the container and the closure are rectangular, a rear side of the closure is pivotally coupled to a rear side of the container, the one or more projections comprises two spaced-apart projections on the inner surface of a front side of the skirt. 
     
     
         3 . The child-resistant box according to  claim 2 , wherein the child-resistant box further comprises two hinge joints pivotally coupling the container and the closure. 
     
     
         4 . The child-resistant box according to  claim 2 , wherein a front wall of the wall of the container is configured to be resiliently depressed inwards under an external force, wherein upon depressing the front wall, the outwardly rolled rim moves inwards to be just past the two spaced-apart projections. 
     
     
         5 . The child-resistant box according to  claim 1 , wherein the one or more projections have a rounded bottom and a flat top similar to a quarter sphere. 
     
     
         6 . A method for restricting access of a child to a container, the method comprising the steps of:
 providing a child-resistant box comprising:
 a container comprising:
 a base and a wall, wherein the base and the wall define an inner volume of the container, 
 the container has an open-top, 
 an outwardly rolled rim along a periphery of the open-top, 
 
 a closure pivotally coupled to the container, the closure comprising:
 a central section and a skirt that extends downwards from a periphery of the central section, 
 the skirt has an inner surface and an outer surface, the inner surface of the skirt has one or more projections, wherein a space between the one or more projections and the central section is proportional to a thickness of the outwardly rolled rim, 
 wherein the outwardly rolled rim is configured to slide over the one or more projections under an external force and retained within the space between the one or more projections and the central section; and 
 
   applying a downward force on the closure resulting in the one or more projections snapping over the outwardly rolled rim.   
     
     
         7 . The method according to  claim 6 , wherein the container and the closure are rectangular, a rear side of the closure is pivotally coupled to a rear side of the container, the one or more projections comprises two spaced-apart projections on the inner surface of a front side of the skirt, wherein the method further comprises the steps of:
 grasping the child-resistant box in hands with thumbs on a front wall of the wall of the container;   depressing the front wall of the container by the thumbs resulting in moving of the outwardly rolled rim inwards; and   lifting the closure outwards and upwards.
