Sealable dispenser for dispensing a fluid, viscous or pasty medium contained in a container

Abstract

A sealable dispenser device for dispensing a fluid, viscous or pasty medium contained in a container, has a dispensing opening for dispensing the medium in the container and a closure device. By operation of the closure device a connection between the dispensing opening and the container may be produced or broken. The closure device is formed by an element that may be displaced along the connection between the dispensing opening and the container. The closure device is embodied such that the above must be displaced onto the container in order to generate a connection between the dispensing opening and the container and must be displaced away from the container in order to break the connection between the dispensing device and the container. Such a device is simple and easy to operate yet cannot open itself under any circumstances.

1 . A sealable dispenser for dispensing a medium selected from the group consisting of a fluid medium, a viscous medium and a pasty medium contained in a container, the sealable dispenser comprising: 
 a dispenser body having a step and a dispensing opening formed therein, said dispenser body connected to the container for dispensing the medium contained in the container; and    a sealing device through whose activation a connection between said dispensing opening and the container can be formed and disconnected, said sealing device having an element which can be moved longitudinally along the connection between said dispensing opening and the container, said sealing device being embodied such that, in order to form the connection between said dispensing opening and the container, said sealing device has to be moved toward the container, and in order to disconnect the connection between said dispensing opening and the container, said sealing device has to be moved away from the container, said sealing device further having a seal which, in a closed state of the dispenser, is pressed downward against said step, said sealing device additionally having a pin and said seal being held by said pin, and said pin can be moved relative to said seal.    
   
   
       2 . The dispenser according to  claim 1 , wherein said dispenser body contains a carrier part and a pouring part fitted onto said carrier part.  
   
   
       3 . The dispenser according to  claim 2 , wherein said carrier part is fitted onto the container and forms a fixed part of the dispenser in a state in which said carrier part is fitted onto the container.  
   
   
       4 . The dispenser according to  claim 2 , wherein said pouring part can be moved in relation to said carrier part.  
   
   
       5 . The dispenser according to  claim 4 , wherein said pouring part can be screwed onto said carrier part to differing degrees.  
   
   
       6 . The dispenser according to  claim 4 , wherein said pouring part can be pushed into said carrier part and pulled out of said carrier part manually.  
   
   
       7 . The dispenser according to  claim 4 , further comprising a lever mechanism, said pouring part can be pushed into said carrier part and pulled out of said carrier part by said lever mechanism.  
   
   
       8 . The dispenser according to  claim 2 , wherein said sealing device is formed by said pouring part or is a component of said pouring part.  
   
   
       9 . The dispenser according to  claim 2 , wherein said step is a component of said carrier part.  
   
   
       10 . The dispenser according to  claim 1 , wherein: 
 said seal has an opening formed therein; and    a movement of said pin which takes place in the closed state of the dispenser causes said seal to be exposed, and in that, by said opening in said seal, pressures which are present on each side of said seal can be equalized.    
   
   
       11 . The dispenser according to  claim 1 , wherein said dispenser body has a separate pressure equalization opening formed therein through which an overpressure or partial vacuum present in the container can be reduced.  
   
   
       12 . The dispenser according to  claim 11 , wherein said pressure equalization opening is disposed such that a person who opens the dispenser with his mouth or who already places said dispensing opening against his mouth while the dispenser is opening is not able to breath in, or is prevented from breathing in, gases which emerge from said pressure equalization opening while the container is vented.  
   
   
       13 . The dispenser according to  claim 11 , wherein the dispenser is embodied such that, during activation which has to be carried out in order to form the connection between said dispensing opening and the container, at first a connection is formed between said pressure equalization opening and the container, and only afterwards is the connection between said dispensing opening and the container formed.  
   
   
       14 . The dispenser according to  claim 11 , wherein the dispenser is embodied such that there is no connection between said pressure equalization opening and the container if there is the connection between said dispensing opening and the container.  
   
   
       15 . The dispenser according to  claim 1 , wherein the container is a drinking bottle.
