Drop cap for dosing the amount of liquid in a drop and container comprising a drop lid

Abstract

The invention relates to a drop cap for dosing the amount of liquid in the form of drops in a container, whereby the contents thereof which are to be dosed can be put under pressure. A throttling device is arranged in the direction of flow upstream from the input opening of the output channel arranged in the body of the cap in order to ensure that a predetermined drop volume is maintained in a reliable manner particularly when large drops are present, whereby said volume should be independent from the pressure applied from the liquid. Said throttling device can be embodied as a permeable opening in an additional separating wall. The invention also relates to a container comprising a drop cap.

         11 . Dropper cap as claimed in any one of  claims 3  to  10 , characterized in that the chamber wall ( 32 ) is molded onto the cap body ( 11 ).  
     
     
         12 . Container ( 1 ) for receiving a liquid that can be put under pressure for dispensing it from the container, with a container neck ( 3 ) with a dropper cap ( 10 ) for dispensing liquids in the form of drops as claimed in any one of  claims 1  to  11 .  
     
     
         13 . Container for receiving a liquid, which can be put under pressure for dispensing it from the container, with a container neck for receiving a dropper cap ( 10 ′) for dispensing a liquid in the form of drops, with a cap body in which a discharge channel is arranged, characterized in that a partition wall ( 34 ′), in which a restrictor device ( 30 ) is provided, is arranged in the interior ( 6 ) of the container ( 1 ).  
     
     
         14 . Container as claimed in  claim 13 , characterized in that the partition wall ( 34 ′) is arranged in the container neck ( 3 ).  
     
     
         15 . Container as claimed in  claim 13  or  14 , characterized in that the partition wall ( 34 ′) is arranged perpendicularly to the container axis.
