Delivery Device With a Reinforced Flexible Wall

Abstract

A delivery device is proposed with an elastically deformable component preferably bounding a pump chamber. In order to achieve improved resetting and/or protection of the component, which is preferably composed of a thermoplastic material, a wall of the component is connected to and/or is covered by an element made of a different material.

       26 . A delivery device for a preferably cosmetic liquid, the delivery device, comprising:
 an elastic or flexible component;   said component including a wall made of a first material; and   an element made of a second material connecting and/or covering said component.   
   
   
       27 . The delivery device as set forth in  claim 1 , wherein said element is connected to said wall by a non-detachable manner. 
   
   
       28 . The delivery device as set forth in  claim 1 , wherein said element is injected to said wall or injected into said wall. 
   
   
       29 . The delivery device as set forth in  claim 1 , wherein said element and said wall include an integral one piece unit. 
   
   
       30 . The delivery device as set forth in  claim 1 , wherein said element forms a continuous material layer or a cover. 
   
   
       31 . The delivery device as set forth in  claim 1 , wherein said element is connected to said wall by at least one arched and/or rib or fin-shaped section extending over said wall. 
   
   
       32 . The delivery device as set forth in  claim 1 , wherein said element is positioned lower said first material, or the wall for protecting the first material, or the wall, respectively, from chemical and/or mechanical influences. 
   
   
       33 . The delivery device as set forth in  claim 1 , wherein said element provides an resetting force upon displacement of said element for bring about, or supporting the elastic resetting of the component instrumentally, or exclusively. 
   
   
       34 . The delivery device as set forth in  claim 1 , wherein said element is connected to the wall, or to the first material, respectively, in a holohedral manner. 
   
   
       35 . The delivery device as set forth in  claim 1 , wherein said wall is arched or dome-shaped. 
   
   
       36 . The delivery device as set forth in  claim 1 , wherein said component, or said wall, respectively, limits or forms a pump chamber of the delivery device. 
   
   
       37 . The delivery device as set forth in  claim 1 , wherein said component, or said wall, respectively, limits or forms a pump chamber of the delivery device;
 an actuating section of said component is adapted to be deformed by pressing down on said actuating section for dispensing the liquid from said pump chamber; and   a resetting force of said component or of said actuating section is automatically suctioning the liquid into said pump chamber.   
   
   
       38 . The delivery device as set forth in  claim 1 , wherein said preferably elastic or flexible component or said first material is covered by said second material such that the surface of said component, or of said first material, respectively, is protected from direct contact with the liquid. 
   
   
       39 . The delivery device as set forth in  claim 1 , wherein said component forms a wall for the liquid. 
   
   
       40 . The delivery device as set forth in  claim 1 , wherein said second material is connected to said first material in a holohedral manner, or only in sections. 
   
   
       41 . The delivery device as set forth in  claim 1 , wherein said second material is extruded on or onto said first material. 
   
   
       42 . The delivery device as set forth in  claim 1 , wherein said first and second materials differ with regard to their composition, resistance to the liquid and/or their other properties. 
   
   
       43 . The delivery device as set forth in  claim 1 , wherein said second material forms a continuous layer, or cover, respectively. 
   
   
       44 . A delivery device for a preferably cosmetic liquid, the delivery device, comprising:
 a pump chamber;   an elastic or flexible component forming part of said pump chamber;   said component including a wall made of a first material;   an element made of a second material connecting and/or covering said component;   said element comprises at least one arched and/or rib or fin-shaped section extending over said wall; and   said element is arranged on the side of said wall facing said pump chamber.   
   
   
       45 . A delivery device for a preferably cosmetic liquid, the delivery device, comprising:
 a pump chamber;   an elastic or flexible component forming part of said pump chamber;   said component including a wall made of a first material;   an element made of a second material connecting and/or covering said component;   said element comprises at least one arched and/or rib or fin-shaped section extending over said wall; and   said element is arranged on the side of said wall opposite of said pump chamber.
