Pumping device with collapsible nozzle

Abstract

There are provided a pumping device for dispensing the contents contained in a container body by pressing a pressurizing button. The pumping device comprises a nozzle which is pivotable by a hinge installed at the nozzle and the pressurizing button. The pressurizing button comprises: a pressing plate, a wall extended downward from the pressing plate, and a nozzle receiving groove formed on the wall and for receiving the nozzle when it is in a closed position. In accordance with the present invention, since the nozzle is foldable, the pumping device is conveniently transported and distributed, and since the nozzle is inserted into the nozzle receiving groove and is not exposed outside, the nozzle is prevented from being unintentionally in an open position by an unnecessary external force.

       5 . The pumping device according to  claim 1 , wherein the nozzle comprises a finger receiving groove. 
   
   
       6 . The pumping device according to  claim 1 , wherein the pressurizing button comprises: a stopper to prevent the nozzle from being excessively deeply inserted into the nozzle receiving groove. 
   
   
       7 . The pumping device according to  claim 1 , wherein the nozzle comprises: a projection formed at an end of the nozzle. 
   
   
       8 . The pumping device according to  claim 1 , wherein the hinge member comprises: a hinge shaft formed at the nozzle, and a hinge aperture formed at the pressurizing button. 
   
   
       9 . The pumping device according to  claim 1 , wherein the hinge member comprises: a hinge aperture formed at the nozzle, and a hinge shaft formed at the pressurizing button. 
   
   
       10 . The pumping device according to  claim 3 , wherein, when the nozzle is in the closed position, an end of the nozzle is caught by a top side of the outer cylindrical body or a top side of the inner cylindrical body, so that the pressing operation of the pressurizing button is prevented. 
   
   
       11 . The pumping device according to  claim 3 , wherein, when the nozzle comprises the raise (R) and is in the closed position, the raise (R) is caught by the top side of the outer cylindrical body, so that the pressing operation of the pressurizing button is prevented. 
   
   
       12 . The pumping device according to  claim 3 , wherein, when the nozzle comprises the projection formed at its end and is in the closed position, the projection is caught by the top side of the outer cylindrical body, so that the pressing operation of the pressurizing button is prevented. 
   
   
       13 . The pumping device according to  claim 2 , characterized in that, when the nozzle is in the closed position, the pressurizing button is prevented from being pressed so that the contents are interrupted from being unintentionally released, and when the nozzle is in an open position, the pressurizing button is capable of being pressed so that the contents are discharged. 
   
   
       14 . The pumping device according to  claim 2 , wherein the nozzle comprises a raise (R). 
   
   
       15 . The pumping device according to  claim 2 , wherein the nozzle comprises a finger receiving groove. 
   
   
       16 . The pumping device according to  claim 2 , wherein the pressurizing button comprises: a stopper to prevent the nozzle from being excessively deeply inserted into the nozzle receiving groove.
