Abstract

The invention relates to a device for opening and closing a closure element which opens along the height thereof when a manual pressure is applied against two removable parts that are resting on a base, which may be coupled with a means for delivering or releasing liquids.

1 . Device for opening and closing a cap of a container comprising two removable parts, a base, and a straw, wherein said removable parts are resting on the base, wherein said base is positioned onto the tip of said container, wherein said straw is coupled to and extends through the base, and wherein the cap is opened along the height by applying pressure onto said removable parts.  
   
   
       2 . Device according to  claim 1 , wherein the base is twisted or threaded onto the tip of said container.  
   
   
       3 . Device according to  claim 1 , wherein the straw has a fixed part and a flexible part and wherein said flexible part is located at the level of the base.  
   
   
       4 . Device according to  claim 3 , wherein said fixed part of the straw has an inner end located below the base and inside the bottle, and an outer end located above the base, and the flexible part may unfold by pulling out the outer end of the straw.  
   
   
       5 . Device according to  claim 1 , wherein said removable parts comprise a vertical abutment or wedge for maintaining the straw in a vertical position when said device is closed.  
   
   
       6 . Device according to  claim 1 , wherein said removable parts comprise a reinforcement cap for sealing the straw.  
   
   
       7 . Device according to  claim 6 , wherein the reinforcement cap comprises a male/female closing system which maintains the reinforcement cap in a tight closed position.  
   
   
       8 . Device according to  claim 7 , which is threaded or twisted to a bottle.  
   
   
       9 . Device according to  claim 1 , which is made of plastic.  
   
   
       10 . A container comprising a device as in  claim 1.
