Silicone Bottle Cap

Abstract

Embodiments of the invention relate generally to a silicone bottle cap comprising a silicone cap whose lower end is open and expanded. Inside the cap there are more than two circular sealing ribs, which are screwed with the threads on the outside of the mouth of the bottle to be sealed. The whole cap is made of silicone, which is a material of flexibility and elasticity. The bottle cap is placed above the bottle mouth and pressed downward to seal the bottle. The circular sealing ribs inside the cap can be screwed with the thread on the outside of the bottle cap. Therefore, the bottle cap will not easily fall off, and the sealing effect is improved. To remove the bottle cap, the lower end of the cap is flapped and the cap is pulled upwards. The bottle cap is easy to use.

What is claimed is: 
     
         1 . A silicone cap comprising: a cap ( 10 ) made of silicon wherein the lower end is open and expanded, more than two circular sealing ribs ( 11 ) inside the cap ( 10 ) which are screwed with the thread ( 101 ) on the outside of the mouth of the bottle ( 100 ). 
     
     
         2 . A silicone bottle cap said in  claim 1 , wherein the lower end of the cap ( 10 ) is molded with an outward-turning lace ( 12 ). 
     
     
         3 . A silicone bottle cap said in  claim 2 , wherein the said lace ( 12 ) has a wave-like shape. 
     
     
         4 . A silicone bottle cap said in  claim 1 - 3 , wherein the said sealing ribs ( 11 ) inside the said cap are parallel with each other. 
     
     
         5 . A silicone bottle cap said in  claim 4 , wherein the top of the said cap ( 10 ) is closed. 
     
     
         6 . A silicone bottle cap said in  claim 4  is special in that the top of the cap ( 10 ) has a closed site of insertion ( 13 ). 
     
     
         7 . A silicone bottle cap said in  claim 4 , wherein the top of the cap ( 10 ) has hollowed-out holes ( 14 ).
