Cap for a container

Abstract

A cap resistant to impact forces and providing a leak-tight fitting to a container whilst allowing simple and quick release.

What is claimed is: 
     
         1 . A cap comprising:
 (i) a cap body capable of being connected to a container, said cap body comprising an outlet opening therein; and   (ii) a lid for coupling with said cap body;   wherein said cap body is capable of being connected to said container with a torque of between about 100 Ncm and about 400 Ncm and wherein said cap body experiences an upwardly deflection of not more than about 0.3 mm.   
     
     
         2 . A cap according to  claim 1  wherein said cap body comprises a spout and wherein said outlet opening is located therein. 
     
     
         3 . A cap according to  claim 2  wherein said spout extends from a first portion defining a top, vertically displaced from an outer wall of said cap body, up to a second portion defining a base, and wherein the distance between an uppermost portion of the top of the spout and an apex of said outer wall is at least about 6 mm. 
     
     
         4 . A cap according to  claim 1  wherein said cap body comprises a female thread for securing onto a container neck threaded accordingly. 
     
     
         5 . A cap according to  claim 3  wherein said cap body comprises a bridge-type portion and wherein said bridge-type portion is formed by a portion of said outer wall of said cap body. 
     
     
         6 . A cap according to  claims 4  and  5  wherein said bridge-type portion comprises:
 (i) a flat notch capable of contacting an uppermost surface of said container neck when said cap body is fully screwed onto said container neck; and 
 (ii) a plug seal proximal said flat notch extending substantially parallel the to a longitudinal axis of said cap body, and capable of contacting at least a portion of an inner surface of said container neck. 
 
     
     
         7 . A cap according to  claim 6  wherein said flat notch and plug seal provide a sealing means when said cap body is screwed tightly to said container neck. 
     
     
         8 . A cap according to  claim 6  wherein said flat notch comprises a flat surface oriented to make contact with said uppermost surface of said container neck when said cap body is fully screwed onto said container neck. 
     
     
         9 . A cap according to  claim 8  wherein a distance “a” between an apex of said bridge-type portion and said flat surface of said flat notch is between about 2 mm and about 3 mm. 
     
     
         10 . A cap according to  claim 5  wherein at least a portion of said bridge-type portion is coated with a material capable of elastically deforming upon application of a force. 
     
     
         11 . A cap according to  claim 10  wherein said material capable of elastically deforming upon the application of a force is not the same material of said cap body, and wherein said material capable of elastically deforming upon the application of a force has a higher elastic deformation than the material of said cap body.
