Patent Name A Bottle Closure Device Patent Applicant Wang Shaohua Principal Applicant Address 261041 Yanzhou Road, No. 709, Kuiwen District, Weifang City, Shandong Province Inventor Wang Shaohua Application (Patent) No. 200410024257.7 Application Date 2004.06.10 Certification Date Approval Notice No. 1706723 Auditing Notice Day 2005.12.14 Manual CD-ROM D0550 main classification number B65D50/04 classification number B65D50/04 division Original application number Priority Claim Abstract The present invention discloses a bottle mouth closure device, the first connector at the bottle mouth and The second connecting body at the bottle cap is screwed to achieve the sealing of the bottle mouth, the first connecting body is integrated with the bottle mouth, and the second connecting body has substantially the same shape as the bottle cap and the clearance is nested in the bottle cap. The two connecting bodies can perform a specified amount of axial movement relative to the bottle cap, and an end surface positioning mechanism is arranged between the second connecting body and the bottle cap. When the bottle cap is subjected to a downward axial force, the positioning mechanism can make the bottle caps When rotating with the second connecting body and the axial force is cancelled, the bottle cap and the second connecting body can relatively freely rotate. The problem that the screw cap is easily opened and the child accidentally eats by mistake is solved. The invention has the advantages of simple structure, convenient and safe, and is widely used for the closure of bottle and mouth of medicines and children's food packaging bottles. Sovereignty item 1. A bottle mouth closing device comprising a first connecting body (4) at a bottle mouth (3) and a second connecting body (2) at a bottle cap (1), a first connecting body (4) and The second connecting body (2) is screwed together to achieve the sealing of the bottle mouth (3), characterized in that the first connecting body (4) is integrated with the bottle mouth (3), and the second connecting body (2) Having substantially the same shape as the cap (1) and having a gap nested within the cap (1), the second connecting body (2) can perform a predetermined amount of axial movement within the cap (1), the second connecting body (2) An end surface positioning mechanism is provided between the bottle cap (1) and the bottle cap (1). When the bottle cap (1) is subjected to a downward axial force, the positioning mechanism can make the bottle cap (1) and the second connecting body (2). When rotating together, the bottle cap (1) and the second connecting body (2) can rotate relatively freely.
