Dosing valve and device for the output of a preferably cosmetic liquid

Abstract

Proposed are a dosing valve and a device provided therewith for the dosed output of a preferably cosmetic liquid. The dosing valve is designed for pressurized filling between a cap and the dosing valve. In order to increase the dosing volume in a simple manner, an additional container connected to the dosing chamber of the dosing valve is provided which is disposed on the valve housing spaced away from the cap and/or has a section with an outer contour which tapers toward the cap.

1 . Dosing valve for the dosed output of a preferably cosmetic liquid under pressure, with a valve housing which forms a dosing chamber of the dosing valve, wherein the valve housing can be supported on the outlet side onto a cap for pressure-tight attachment to a container storing the liquid and wherein the dosing valve is designed for pressurized filling, with the dosing valve having a rigid additional container which is connected to the dosing chamber and enlarges same.  
   
   
       2 . Dosing valve according to  claim 1 , wherein the additional container is designed as a separate part.  
   
   
       3 . Dosing valve according to  claim 1 , wherein the dosing valve has at least one of the following: valve element, inlet valve or outlet valve.  
   
   
       4 . Dosing valve according to  claim 1 , wherein the additional container is stuck, snapped or clamped onto the valve housing or formed or injection-molded thereon.  
   
   
       5 . Dosing valve according to  claim 1 , wherein the additional container is connected inseparably to the valve housing, particularly by means of welding, adhesion, press fit and/or form fit.  
   
   
       6 . Dosing valve according to  claim 1 , wherein the additional container is designed in a single piece with the valve housing and/or is injection-molded onto the valve housing.  
   
   
       7 . Dosing valve according to  claim 1 , wherein the additional container and/or the valve housing is/are designed to be at least essentially rotationally symmetrical, cylindrical and/or oblong.  
   
   
       8 . Dosing valve according to  claim 1 , wherein the additional container encloses, peripherally, cylindrically or radially, the valve housing, an inlet port of the dosing valve and/or an ascending duct which is adjacent thereto on the inlet side.  
   
   
       9 . Dosing valve according to  claim 1 , wherein the additional container is adjacent to the valve housing at the end of the valve housing on the inlet side and/or the end of the valve housing opposite the cap and extends away from the cap.  
   
   
       10 . Dosing valve according to  claim 1 , wherein the additional container is disposed or arranged only on the inlet side of the valve housing and/or is spaced away from the cap.  
   
   
       11 . Dosing valve according to  claim 1 , wherein the additional container has a section with an outer contour which tapers to the outlet-side end of the valve housing or toward the cap.  
   
   
       12 . Dosing valve according to  claim 1 , wherein the additional container has an ascending channel.  
   
   
       13 . Dosing valve according to  claim 12 , wherein the ascending channel is designed in an annular ring shape and/or is disposed within the additional container.  
   
   
       14 . Device for the dosed output of a preferably cosmetic liquid, with a container that is sealed by a cap for the liquid and a dosing valve which is attached to the cap, wherein the dosing valve is designed for pressurized filling, wherein the dosing valve has a valve housing with a dosing chamber for the dosing of the liquid, wherein the dosing valve has a rigid additional container which is connected to the valve housing in order to enlarge the dosing chamber.  
   
   
       15 . Device according to  claim 14 , wherein the container can be filled or is filled by means of pressurized filling with the liquid and/or a propellant, particularly gas.  
   
   
       16 . Device according to  claim 14 , wherein the container contains one of the following: hairspray, hair lacquer, deodorant, foam, gel, color spray, sun protection agent, skincare agent, cleaning agent, cosmetic agent, air improver, construction foam or adhesive in the form of a liquid.  
   
   
       17 . Method for the manufacture of a dosing valve which is designed for pressurized filling, with a valve housing and an additional container disposed thereon, wherein the method comprises the following steps: 
 preparation of the valve housing with a dosing chamber formed therefrom for a liquid or a mixture of liquid and propellant;    preparation of an additional container; and    connection of the additional container with the valve housing or an inlet port of the valve housing for enlarging the dosing chamber.    
   
   
       18 . Method according to  claim 17 , wherein the additional container is mounted onto the valve housing or the inlet port.  
   
   
       19 . Method according to  claim 17 , wherein the additional container is snapped onto the valve housing or the inlet port.  
   
   
       20 . Method according to  claim 17 , wherein the additional container is clamped onto the valve housing or the inlet port.
