Abstract

A liquid agent applicator including a collapsible reservoir for storing the liquid agent, and a shaft having a lumen there through connected to the collapsible reservoir. The liquid agent applicator also includes an opening mechanism that is inserted into an orifice in one end of said shaft. The liquid agent applicator being sealed by a breakable seal formed between the opening mechanism and the shaft, wherein twisting of the opening mechanism relative to the shaft breaks the seal allowing egress of the liquid agent stored in the reservoir.

1 . A liquid agent applicator comprising: 
 a collapsible reservoir for storing the liquid agent;    a shaft having a lumen there through connected to said collapsible reservoir;    an opening mechanism inserted into an orifice formed in one end of said shaft; and    a breakable seal formed between said opening mechanism and said shaft, wherein twisting of said opening mechanism relative to said shaft breaks said seal allowing egress of the liquid agent stored in said reservoir.    
     
     
         2 . The liquid applicator of  claim 1 , wherein said seal is formed by thermoforming.  
     
     
         3 . The liquid applicator of  claim 1 , wherein said seal is formed between the opening mechanism and an interior surface of said shaft.  
     
     
         4 . The liquid applicator of  claim 1 , wherein said seal is formed by matching threads formed on said opening mechanism and said shaft.  
     
     
         5 . The liquid applicator of  claim 1 , wherein said seal is formed by the elastic properties of said shaft conforming to the shape of said opening mechanism inserted therein.  
     
     
         6 . The liquid applicator of  claim 1 , further comprising grips formed on said reservoir.  
     
     
         7 . The liquid applicator of  claim 1 , further comprising a flat base.  
     
     
         8 . The liquid applicator of  claim 1 , wherein said reservoir is formed by thermoforming one or more sheets of plastic material.  
     
     
         9 . The liquid applicator of  claim 1 , formed of a chemically compatible material for use with anti-flea and tick agents.  
     
     
         10 . The liquid applicator of  claim 1 , wherein said opening mechanism is child resistant.  
     
     
         11 . The liquid applicator of  claim 10 , wherein the child resistant opening mechanism comprises: 
 a rigid stationary neck;    a movable cap;    a septum for preventing the egress of liquid from said reservoir formed on said stationary neck;    a punch formed on said movable cap, for piercing said septum to allow the egress of liquid from said reservoir; and    an interlock requiring two or more movements of said movable cap by the user, wherein upon completion of said two or more actions, said movable cover is movable along said stationary neck in the direction of said septum, the movement of said movable cap causing said punch to pierce the septum.    
     
     
         12 . The liquid agent applicator of  claim 1  wherein the liquid agent is topical pharmaceutical or veterinary formulation.  
     
     
         13 . The liquid agent applicator of  claim 1 , wherein the applicator is formed poly acrylo nitrile.
