Stopper with air intake

Abstract

The present invention relates to a stopper intended to be mounted on a container, of the bottle type, containing a liquid, a base provided with means for mounting on the container, a mouthpiece intended to be positioned in the user's mouth to remove the liquid from the container, an air inlet allowing air into the container in response to the removal of the liquid, said mouthpiece comprising at least one duct communicating with the internal volume of the container and ending toward the outside in the form of an outlet orifice, wherein the air inlet comprises at least one fluid passage one of the ends of which opens to the outside and the other end of which opens near the outlet orifice which, with this other end, are intended to be introduced into the user's mouth.

1 . A stopper intended to be mounted on a container, of the bottle type, containing a liquid, a base provided with means for mounting on the container, a mouthpiece intended to be positioned in the user's mouth to remove the liquid from the container, an air inlet allowing air into the container in response to the removal of the liquid, said mouthpiece comprising at least one duct communicating with the internal volume of the container and ending toward the outside in the form of an outlet orifice, wherein the air inlet comprises at least one air passage one of the ends of which opens to the outside and the other end of which opens near the outlet orifice which, with this other end, are intended to be introduced into the user's mouth.  
     
     
         2 . The stopper as claimed in  claim 1  and which comprises at least two ducts.  
     
     
         3 . The stopper as claimed in  claim 1  or  2 , wherein the mouthpiece comprises ducts of approximately semicircular cross section spaced apart by a slot forming the air passage, said slot extending from the base up to the level of the outlet orifices.  
     
     
         4 . The stopper as claimed in  claim 1 , wherein the mouthpiece comprises a duct provided with an outlet orifice, with a cylindrical collar, concentric and connected to the duct by bridges of material, thus delimiting an annular space, which extends from the outlet orifice with one of its ends as far as a peripheral slot defined between the base and said collar, said peripheral slot allowing the annular space to communicate with the outside.  
     
     
         5 . The stopper as claimed in any one of  claims 1  to  4 , and which comprises a retractable cap attached to the mouthpiece and allowing the outlet orifice to be sealed off.  
     
     
         6 . A bottle comprising a stopper as claimed in any one of  claims 1  to  5 .
