Sealing cap

Abstract

A sealing cap includes radial wave-like stripes on an upper surface, a pull hole and an extended-out rod projections formed on one side, a brim formed on the other side of the pull hole and ridges formed on an inner surface of the annular circumferential vertical wall. The thickness of the stripes gradually becomes thinner from the outer circumference to the center. In using, a user holds the pull hole with fingers inserted therein, and with the other hand pulling the brim down to seal the sealing cap on a container. Then the moist and taste of the food stored in the container can be prevented from dispersing out. In addition, the sealing cap cannot be broken in handling process of sealing by means of the elasticity produced by the structure of the stripes with its thinness gradually becoming thinner from the outer circumference to the center.

1 . A sealing cap comprising a plurality of radial wave-like stripes on an upper surface, a pull hole formed at one side of its outer circumference, a brim formed at the other side of said pull hole, a plurality of ridges formed in an inner surface of an annular circumferential vertical wall, said radial wave-like stripes having a thinness gradually becoming thinner from the outer circumference to the center; 
 said pull hole being held by fingers of a user, said sealing cap being placed on an upper opening of a container and with one hand pulling said brim to seal said sealing cap down around the upper side of the container, the container stored with food sealed by said sealing cap so as to prevent the moist and taste of the food from dispersing out, said sealing cap possible to be hampered from broken during the seal handling process by the elasticity of said sealing cap provided with said thickness of said stripes gradually becoming thinner from the outer circumference to the center.    
   
   
       2 . The sealing cap as claimed in  claim 1 , wherein said sealing cap is made of high polymer elastomer.
