Push-To-Open Container

Abstract

The container contains a cap element, a hollow case member with an open top side, a tab element, and an elastic element. The cap element is hinged to the case member so that the cap element can be flipped to reveal or cover the case member. The tab element is hinged to a front side of the case member locking the cap element, and the elastic element is configured to a rear side of the case member that is bended by the cap element when the cap element closes the case member. When the tab element is depressed, the cap element is released, and the elasticity of the elastic element pushes open the cap element. The elastic element helps reducing the friction between the cap element and the case member, thereby enhancing the convenience and reliability of opening the container.

1 . A push-to-open container, comprising:
 a hollow case member with an open top side;   a cap element having a rear edge hinged to a top rear edge of the case member and an indentation adjacent to the rear edge where the cap element is able to be flipped into an open position to reveal or in a closure position to cover the open top side of the case member;   a tab element hinged to a front side of the case member locking the cap element when the cap element is in the closure position; and   an elastic element comprising a major piece configured to the rear side of the case member and an elastic arm extended below a bottom side of the cap element through the indentation from a top edge of the major piece, where the elastic arm is in an upright position when the cap element is in the open position, and the elastic arm is concealed and bended by the cap element in a forward bending position when the cap element is in the closure position;   wherein, when the cap element is in the closure position and the tab element is depressed, the tab element releases the cap element; the elasticity of the elastic arm restores the elastic arm to the upright position from the forward bending position; and the cap element is pushed open by the restored elastic arm into the open position.   
     
     
         2 . The push-to-open container according to  claim 1 , wherein the cap element comprises a first lock piece on a bottom side adjacent to a front edge of the cap element; the tab element comprises a second lock piece along a rear edge of a top section of the tab element; and the second lock piece locks the first lock piece when the cap element is in the closure position.
