Description

A kind of bottle cap

Technical field:

The utility model relates to a kind of improvement of bottle cap with exposing bottle mouth sealing film function.

Background technology:

For improving the shelf-life and preventing the seepage of bottle interior beverage in transport storing process, the bottleneck of now a lot of bottled drinks has sealed membrane to seal, simultaneously go out stamp point in the top design of bottle cap, in the time that needs are opened sealed membrane, bottle cap is taken off and expose sealed membrane with stamp point, very convenient.But, stamp point is being exposed after sealed membrane, the sealed membrane otch remaining on bottleneck can fitly not abut in bottleneck inner side, the very large shortcoming of bringing is to be unfavorable for pouring out of bottle interior beverage, make sealed membrane otch fitly abut in bottleneck inner side if roll sealed membrane otch with hand, very careful, slightly carelessly possibly finger is cut.Thus, also there is certain defect in prior art.

Summary of the invention:

In view of the deficiency of background technology, the purpose of this utility model aims to provide a kind of function with exposing bottle mouth sealing film, and can make the sealed membrane otch being pierced fitly abut in bottleneck inner side, not only be beneficial to the hand that cuts of pouring out but also prevent sealed membrane otch of bottle interior beverage, improved the bottle cap of ease of use and safety.

The utility model takes following technical scheme to complete:

A kind of bottle cap, the stamp point that comprises plastic cover and arrange at plastic cover top, it is characterized in that: the top capping of plastic cover is provided with round boss, between the top capping of the cylindrical of round boss and plastic cover, be provided with arc-shaped transition, described stamp point is at the end face setting of round boss the edge of close round boss.

Adopt the bottle cap of technique scheme, after bottle mouth sealing film being exposed with stamp point, along with the rotation of bottle cap, stamp point can enclose sealed membrane one all and expose, simultaneously in the rotation process of bottle cap, arc-shaped transition between round boss cylindrical and plastic cover top capping can roll the sealed membrane otch remaining on bottleneck and make sealed membrane otch fitly abut in bottleneck inner side (only need consider when design that the size at arc-shaped transition position mate with bottleneck size), thereby realize the hand that cuts of pouring out but also prevent sealed membrane otch that had not only been beneficial to bottle interior beverage, improve ease of use and safety.

As preferably, the height of round boss is controlled between 1.5mm-2.5mm.Plastic cover, round boss and stamp point are integral molded plastic moulding.
