Dosage dispenser

Abstract

The aim of the invention is to simplify the construction of a dosage dispenser ( 1 ) for dosing at least one component that is contained in a receptacle section ( 10 ), by means of a pump unit ( 6 ) connected to said section and a pump plunger ( 6 ′), which is inserted in said unit and can be actuated by means of an actuating element ( 3 ) using a handle ( 7 ), in particular about a horizontal pivoting axis ( 4 ) in a housing head ( 8 ) and which is connected to a delivery nozzle ( 9 ). To achieve this aim, the upper region of the pump unit ( 6 ) has an annular channel ( 21 ) facing towards the delivery nozzle ( 9 ).

1 . A dosage dispenser for dosing at least one component that is contained in a receptacle section, which occurs by a pump unit connected to said section and a pump plunger which is inserted in said unit and can be actuated by an actuating element using a handle, especially about a horizontal pivoting axis in a housing head, and which is connected to a delivery nozzle, wherein the pump unit comprises in its upper region an annular channel facing towards the delivery nozzle.  
   
   
       2 . A dosage dispenser according to  claim 1 , wherein the pump unit and/or the delivery nozzle is/are formed integrally on a mixing unit, especially by means of injection molding.  
   
   
       3 . A dosage dispenser according to  claim 1  wherein the annular channel has a cross section which widens towards the delivery nozzle.  
   
   
       4 . A dosage dispenser according to  claim 2  wherein the pump unit is inserted in a housing which is connected with the mixing unit by an ultrasonic weld seam.  
   
   
       5 . A dosage dispenser according to  claim 4 , wherein the annular channel is enclosed by the ultrasonic weld seam.  
   
   
       6 . A dosage dispenser according to  claim 4  wherein the ultrasonic weld seam is provided with the shape of a figure-of-eight curve.  
   
   
       7 . A dosage dispenser according to  claim 1  wherein the pump unit comprises a tappet each which extends towards the respective receptacle section.  
   
   
       8 . A dosage dispenser according to  claim 1  wherein a pin-like extension each is provided around the pump unit(s).  
   
   
       9 . A dosage dispenser according to  claim 7  wherein the tappet is substantially arranged within the extension.  
   
   
       10 . A dosage dispenser according to  claim 9 , wherein the tappet is in contact with a locking element of the receptacle section.  
   
   
       11 . A dosage dispenser according to  claim 1  wherein the housing comprises two webs in its center, with a separating wall of the delivery nozzle engaging between the same.  
   
   
       12 . A dosage dispenser according to  claim 1  wherein the housing comprises an indexing, especially a pin, which engages in a respective recess of the mixing unit.
