Integrated wide-mouth bottle cap with disposable and breakable inner plug

Abstract

The present invention is an integrated wide-mouth bottle cap with a disposable and breakable inner plug comprising a lower cover, an upper cover and an inner plug. The lower cover comprises an opening. The upper cover extends integrally from one side of the lower cover, and the upper cover rotates relatively to the lower cover to fasten the lower cover and seals the opening. The inner plug integrally extends from the lower cover adjacent to the periphery of opening and seals the opening. The inner plug comprises a tearing zone between the inner plug and the lower cover, the inner plug comprises a tearing member for a user to pull in order to drive the inner plug displacement relative to the lower cover, so as to disengage the inner plug from the lower cover and expose the opening by tearing off the tearing zone.

What is claimed is: 
     
         1 . An integrated wide-mouth bottle cap with a disposable and breakable inner plug, comprising:
 a lower cover, the lower cover comprising an opening;   an upper cover, the upper cover extending integrally from one side of the lower cover, and the upper cover rotating relative to the lower cover to fasten the lower cover and thereby sealing the opening; and   an inner plug, the inner plug integrally extending from the lower cover adjacent to a periphery of the opening and sealing the opening, the inner plug and the lower cover comprising a tearing zone therebetween, and the inner plug being connected to a tearing member for a user to pull the tearing member to drive the inner plug displacement relative to the lower cover, and the inner plug being disengaged from the lower cover to expose the opening by tearing off the tearing zone.   
     
     
         2 . The integrated wide-mouth bottle cap with the disposable and breakable inner plug as claimed in  claim 1 , wherein the lower cover is a ring and comprises a flange at an inner edge, the upper cover comprises a groove corresponding to the flange, and the flange is inserted and fastened into the groove. 
     
     
         3 . The integrated wide-mouth bottle cap with the disposable and breakable inner plug as claimed in  claim 2 , wherein an outer edge of the lower cover comprises a recessed area, and the recessed area is adjacent to one side of the flange. 
     
     
         4 . The integrated wide-mouth bottle cap with the disposable and breakable inner plug as claimed in  claim 1 , wherein upper and lower sides of the lower cover respectively comprise an upper arcuate edge and a lower arcuate edge which are symmetrically disposed and bent outwardly, left and right sides respectively comprise a left straight edge and right straight edge which are vertically disposed, lengths of the upper arcuate edge and the lower arcuate edge are equal, and longer than lengths of the left straight edge and the right straight edge. 
     
     
         5 . The integrated wide-mouth bottle cap with the disposable and breakable inner plug as claimed in  claim 4 , wherein the upper cover is formed by integrally extending from a middle portion of the upper arcuate edge of the lower cover. 
     
     
         6 . The integrated wide-mouth bottle cap with the disposable and breakable inner plug as claimed in  claim 5 , wherein the lower cover is connected with the upper cover by a bent section. 
     
     
         7 . The integrated wide-mouth bottle cap with the disposable and breakable inner plug as claimed in  claim 6 , wherein the bent section comprises a main connector and two auxiliary connectors by two sides of the main connector. 
     
     
         8 . The integrated wide-mouth bottle cap with the disposable and breakable inner plug as claimed in  claim 1 , wherein the tearing zone is a film structure. 
     
     
         9 . The integrated wide-mouth bottle cap with the disposable and breakable inner plug as claimed in  claim 1 , wherein the tearing member is a pull-ring structure. 
     
     
         10 . The integrated wide-mouth bottle cap with the disposable and breakable inner plug as claimed in  claim 1 , wherein a connection between the tearing member and the inner plug comprises a reinforcing structure.
