Dispensing device

Abstract

The invention relates to a dispensing device for a preferably cosmetic liquid, and to a method for producing one such dispensing device. Two components are interconnected in a liquid-tight manner. The first component comprises a recess and the second component comprises a projection. The projection engages in the recess by means of a section which is complementary to the recess. The connection is created by means of a temporarily liquefied and/or deformed material which is formed by a second section connected to the first section of the projection and/or is injected into the recess, especially via a channel through the projection.

1 . Dispensing device for a cosmetic liquid, with a first component and a second component which are connected or can be connected with each other in a liquid-tight and non-detachable manner, wherein the first component has a groove-like recess and the second component has a projection with a first ridge-like section complimentary to the recess which engages in the recess in the connected state and is connected to the wall of said recess through temporarily liquefied and/or deformed material that is formed by a second section of the projection or injected into the recess. 
     
     
         2 . Dispensing device as set forth in  claim 1 , wherein the recess is closed on the end facing away from the second component, particularly wherein the material in the area of the closed end connects the projection with the recess wall and/or fills out gaps between the projection and the recess wall. 
     
     
         3 . (canceled) 
     
     
         4 . Dispensing device according to  claim 1 , wherein the second section extends to the bottom of the recess in the unconnected state. 
     
     
         5 . Dispensing device according to  claim 1 , wherein the second section tapers toward the bottom of the recess in the unconnected state, particularly is at least substantially trapezoid-shaped or triangular in cross section. 
     
     
         6 . Dispensing device according to  claim 1 , wherein the first section ( 22 ) is at least substantially rectangular in cross section and/or the recess is at least substantially rectangular in cross section. 
     
     
         7 . Dispensing device according to  claim 1 , wherein the first section has at least one channel that extends from the free end preferably to the other side of the second component and through which the material is injected, particularly so that the material fills the lateral space between the projection and the recess wall at least in part. 
     
     
         8 . Dispensing device as set forth in  claim 7 , wherein the channel ( 30 ) is embodied as a slit, particularly as a longitudinal slit. 
     
     
         9 . Dispensing device according to  claim 7 , wherein the projection is provided with several channels ( 30 ). 
     
     
         10 . Dispensing device as set forth in  claim 1 , wherein the recess is embodied as a through hole and the projection reaches through it, with the second section being deformed and/or liquefied such that it engages behind the through hole. 
     
     
         11 . Dispensing device as set forth in  claim 10 , wherein the second section is deformed by one or more of thermally and ultrasound. 
     
     
         12 . Dispensing device according to  claim 13 , wherein the second component has a raised area on the side facing away from the projection for the targeted introduction of ultrasound by means of a transmission element that can be mounted. 
     
     
         13 . Dispensing device according to  claim 1 , wherein the recess is formed in a flat section of the first component. 
     
     
         14 . Dispensing device according to  claim 1 , wherein the projection protrudes from a flat section of the second component. 
     
     
         15 . Dispensing device according to  claim 13 , wherein the two flat sections lie on top of each other when the components are connected. 
     
     
         16 . Dispensing device according to  claim 1 , wherein the first and/or second component is manufactured from a polyolefin, particularly polypropylene or polyethylene, especially preferably LLPE, TPEE or TEEE. 
     
     
         17 . Dispensing device according to  claim 1 , wherein the first and, particularly, second component delimit or form a particularly elastically, preferably manually, deformable pump chamber of the dispensing device. 
     
     
         18 . Dispensing device according to  claim 1 , wherein the dispensing device is embodied as a dispenser, pump or atomizer and/or can be operated manually. 
     
     
         19 . Dispensing device according to  claim 1 , wherein the dispensing device is embodied as a preferably mountable dispensing or spray head. 
     
     
         20 . Method for the manufacture of a dispensing device for a preferably cosmetic liquid, with two components connected in a liquid-tight manner, wherein a projection of a second component is inserted into a recess of a first component and wherein a portion of the projection is deformed and/or liquefied or liquid material is injected through a channel through the projection in order to connect the two components with each other.
