Liquid container spill proof closure/lid/cap

Abstract

A spill proof closure ( 3, 9, 13, and 20 ) is provided which can be employed with a wide variety of containers and liquids. The caps ( 3, 9 ) can be used to replace the cap provided by the manufacture to prevent spills when poring the liquid in the container ( 5, 11 ) in to a receptacle. The seal ( 13, 20 ) can be used by a manufacture to replace the removable seal they already use to make their container ( 14, 17 ) spill proof the first time it is used.

1 . A cap with a hole in the top and a lid hinged to the cap so that when the lid is closed on the cap it latches in place and will release when a pressure is applied by squeezing the container the cap is on. 
     
     
         2 . A cap with a hole in the top similar to  claim 1  with a stopper instead of a lid and a string passing through the hole and attached to a retainer that will pass through the opening of the container but not the hole in the cap so that when the stopper is placed in the hole it will pop out when pressure is applied by squeezing the container the cap is on. 
     
     
         3 . A manufacture provided seal on top of the container that has perforations in the seal that will allow it to bust open under pressure when the container is squeezed, this action would be prohibited from occurring when the manufacture provided cap is in place. 
     
     
         4 . A manufacture provided seal on top of the container that has a glue that will release under pressure when the container is squeezed and is held to the container with a strip down the side of the neck, this action would be prohibited from occurring when the manufacture provided cap is in place.
