Two-piece bottle plug

Abstract

The invention relates to a two-piece bottle plug which mainly comprises a plug body and a pressing piece, wherein the plug body is integrally formed in a cup shape and is provided with a barrel part, a top disc and a plurality of rib parts inside the barrel part; the top disc is connected to the opening end of the barrel part; the diameter of the top disc is more than that of the barrel part; theplurality of rib parts protrude radially on the inner wall of the barrel part and are mutually separated without connection; each rib part is provided with a butting part; the plurality of butting parts are positioned on the same circumference and protrude towards the central direction; a top part and a pole are formed on the pressing piece; the pole extends from one surface of the top part; a jacking part and a bucking part are formed on the surface of the pole; and the diameter of the buckling part is less than that of the jacking part. The bottle plug can be easily manufactured so that themanufacturing cost of the bottle plug can be reduced; in addition, when the bottle plug is used at the opening part of a vessel, the opening of the vessel can be closely sealed.

Description

technical field [0001] The invention relates to a two-piece bottle stopper, in particular to a bottle stopper which can be conveniently processed and manufactured and can tightly close the opening of a container. Background technique [0002] Please read Figure 9 As shown, it is the invention patent case of No. 505600 "Bottle Stopper" applied for by the applicant in Taiwan Patent Announcement of China. Establish the hole 93 that is deep in the cylinder portion 92, and the wall forming the hole 93 has an abutted portion 94, which can be abutted against by the rod body 96 of the pressure column 95, so that the cylinder portion 92 of the closing body 9 acts as a diameter. To expand to close the opening of a container such as a bottle. [0003] Above-mentioned bottle stopper 9 is only made of closing body 90 and pressure column 95, therefore, although the manufacturing cost of this bottle stopper 9 can be reduced. However, the sealing body 90 is mainly made of materials such ...

AI Technical Summary

Problems solved by technology

[0007] If the above-mentioned airtight bottle stopper 7 is only composed of the closing body 71 and the pressure column 72, the airtight bottle stopper 7 still has the problem of being unable to be airtight.

If the head 711 and the petals 715 are integrally molded with rigid plastic material, since the diameter of the protruding ring 723 of the pressure post 72 is larger than the counterbore 713 of the head 711, how to make the protruding ring 723 pass through the Counterbore 713 is also a big problem for manufacturing. Moreover, if this airtight bottle stopper 7 is integrally formed with hard plastic material when making this head 711 and flap 715, the manufacturing cost of this airtight bottle stopper 7 cannot be achieved. effectively reduce
