Liquid container

Abstract

A liquid container ( 10 ) has a base portion ( 12 ) and a cap portion ( 14 ) which are engaged with one another for relative slidable linear movement. The cap has an upwardly facing recess ( 29 ). Initially, the cap portion ( 12 ) and the base portion ( 13 ) define a hermetically sealed chamber ( 42 ) containing a liquid ( 40 ). Upon relative movement of the cap portion ( 14 ) and the base portion ( 12 ), the base enters the chamber ( 42 ) and the hermetic seal is broken so that the liquid ( 40 ) is urged into the recess ( 29 ) of the cap portion ( 14 ).

1 . A liquid container comprising a base portion and a cap portion, wherein the cap portion is engaged with the base portion and is arranged for relative slidable linear movement relative to the base portion, the cap portion defines an upwardly facing recess, the cap portion and the base portion defining initially a hermetically sealed chamber arranged to receive a liquid, and wherein upon relative movement of the cap portion and the base portion in which the cap portion enters the chamber, the hermetic seal is broken and liquid is urged into the recess of the cap portion. 
     
     
         2 . A liquid container according to  claim 1 , wherein the base portion comprises a base having an open topped upstanding endless wall projecting upwardly therefrom, the endless wall of the base portion is provided on an inner surface thereof adjacent an upper end with a seal means which extends around the entire inner surface of the endless wall such that initially a region of the inner wall below the seal means is hermetically sealed by a lower end of the cap engaged with the inner wall. 
     
     
         3 . A liquid container according to  claim 2 , wherein the cap portion has an inner endless wall which is of complementary shape and size to the endless wall of the base portion. 
     
     
         4 . A liquid container according to  claim 2 , wherein the cap portion has an inner endless wall which is of complementary shape and size to the endless wall of the base portion, and an endless cover is mounted to and spaced from the inner endless wall of the cap portion and extends downwardly relative to the wall of the base portion externally thereof. 
     
     
         5 . A liquid container according to  claim 2 , wherein the cap portion has an inner endless wall which is of complementary shape and size to the endless wall of the base portion, and an endless cover is mounted to and spaced from the inner endless wall of the cap portion and extends downwardly relative to the wall of the base portion externally thereof, the endless wall of the cap portion is provided at an intermediate height with an aperture which extends through the entire thickness thereof such that as the cap portion is depressed the hermetic seal is lost as the aperture engages with the seal means, such that liquid in the chamber is forced up by the cap portion between the endless wall of the base and the endless wall of the cap portion to flow into the recess of the cap portion through the aperture. 
     
     
         6 . A liquid container according  claim 1 , wherein a flange extends laterally outwardly from an upper end of the cap portion for manual engagement by a user. 
     
     
         7 . A liquid container according to  claim 1 , wherein the cap portion has an inner endless wall which is of complementary shape and size to the endless wall of the base portion, and an endless cover is mounted to and spaced from the inner endless wall of the cap portion and extends downwardly relative to the wall of the base portion externally thereof, wherein flange extends laterally outwardly from the endless cover adjacent a lower end thereof for manual engagement by a user. 
     
     
         8 . A liquid container according to  claim 1 , in which a liquid is contained initially in the region between the lower end of the cap and the base portion.
