Pop-up Push Lid

Abstract

A conventional pop-up latch mechanism to which a second rotating tongue that will disengage the main latch is used in combination. This tongue is moved in place by pressing on the lid a similar way as to close it. It allows for the design team to have a much wider freedom of designing the closure, without the need to have an area dedicated for the pop-up activation device, reducing mold complexity and cost at the same time. The lid is open by a very simple push down motion. It also requires the user to reach a certain amount of force to open it avoiding accidental opening in case the closure fall on the ground. A slightly recessed lid leads the user to push on the lid.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 
     
         1 . A pop-up push lid device comprising at least:
 a base;   a cover or lid;   the lid and a base, attached together by means of one or several living hinges;   a reach-in area;   a front cover latch for the user to open the cover and refill the tub;   a fastening feature that the lid latch hooks on to keep the lid closed;   a disengaging tongue is connected to the base near the latch mechanism of the fastening feature;   a spring to accumulate elastic energy in order to move the lid; and   wherein, the lid articulates with the cover.   
     
     
         2 . The device of  claim 1 , wherein the lid and base can be obtain through one or several phase of plastic injection molding. 
     
     
         3 . The device of  claim 1 , wherein the disengaging tongue is connected to the base with a living hinge or other fastening method. 
     
     
         4 . The device of  claim 1 , wherein
 the lid is assembled to a cover through a living hinge or other fastening method;   the lid pivots around an axis; and   the base has a reach-in area.   
     
     
         5 . The device of  claim 1 , wherein when the lid is closed, it should cover a maximum of the reach-in area in order to provide a good moist sealing. 
     
     
         6 . The device of  claim 1 , wherein the tongue is articulated around the base and close to the latch so that the extremity with the disengaging feature is beneath the main latch mechanism. 
     
     
         7 . The device of  claim 1 , wherein when the lid is open,
 simply pushing on it until a click latch has engaged;   in the same time, the lid will fold a spring to store energy.   
     
     
         8 . The device of  claim 1 , wherein to open the lid,
 push the lid further down;   the latch will engage with the disengaging feature of the tongue;   release the push force on the lid;   the spring will start to push on the lid;   while the latch is going up, it will hit the main latch retaining feature on the base but cannot engage with it as it is obstructed by the disengaging feature of the tongue;   the lid will then continue its opening course;   the disengaging feature is design such that the spring force is enough to disengage the tongue retaining feature, the lid can now fully pop open.   
     
     
         9 . A pop-up push lid apparatus comprising
 a lid;   a base;   a spring;   the lid and based attached together by a conventional latch mechanism; and   a second rotating tongue that will disengage the main latch.   
     
     
         10 . The apparatus of  claim 9 , wherein the tongue is moved in place by pressing on the lid in a similar way as to close it. 
     
     
         11 . The apparatus of  claim 9 , wherein the lid opens by a push down motion when a certain amount of force to open it is applied. 
     
     
         12 . The apparatus of  claim 9 , wherein the lid is recessed lid so that it leads the user to push on the lid. 
     
     
         13 . The apparatus of  claim 9 , wherein the tongue is articulated around the base and close to the latch so that the extremity with the disengaging feature is beneath the main latch mechanism. 
     
     
         12 . The apparatus of  claim 9 , wherein
 the latch will engage with the disengaging feature of the tongue;   the spring will start to push on the lid, while the latch is going up;   the spring will hit the main latch retaining feature on the base but cannot engage with it as it is obstructed by the disengaging feature of the tongue;   the lid will then continue its opening course;   the spring force is enough to disengage the tongue retaining feature; and   the lid can now fully pop open.
