Abstract

The utility model relates to an easy-to-open bottle cap, which comprises a crown-shaped tooth edge 2, a cover top 6, a pull ring 3 and a rivet buckle 4 and is characterized in that the periphery of the cover top is provided with a bulgy outer edge; the pull ring 3 of which the height is corresponding to that of a flange 7 tightly clings to the inner loop of the flange, and the base part of the pull ring is fixed by the rivet buckle 4 which bulges; the base part of a cutting line 5 is arranged on the cover top 6 which is adjacent to the outer edge. The flange 7 and the pull ring 3 of the utility model are simultaneously positioned at the same plane, and therefore, in the processes of use and transportation, the phenomenon that covers are clamped and are mutual buckled can not happen. The utility model has the advantages of safe transportation and convenient and reliable use.

Description

Easily opened bottle cap

Technical field

The utility model relates to a kind of glass cap, particularly about the easy-open end of beer bottle or glass pop bottle.

Background technology

The pop bottle of glass or top of wine bottle, existing multiple design form, but in the actual production use, remain, can't apply so far in many problems, for example need be excessive when opening bottle cap with pulling force, the ordinary people is not easy to manipulate, and overexerts and cuts the hidden danger of finger in addition, is that caping is uneven again, easily mutual buckle spurs and produces leakage phenomenon in canned or handling process, produces spring when serious and covers the danger of hurting sb.'s feelings.Be that making easy-open bottle lid cost is higher in addition, the too much area of bottle cap because draw ring accounts for, it is too small to be used for the embellish and pressing area, use producer to raise the cost, but can't it is supporting on the kind of higher class, above defective solves by needing, and easily opened bottle cap is progressively promoted the use of.

Summary of the invention

The purpose of this utility model is at the existing use defective of above-mentioned glass bottle easy-open lid existing easy-open bottle lid to be improved, and it is laborsaving design a kind of unlatching, carries and safe in utilization, and can satisfy the easy-open bottle lid of producer's print advertisements needs.

The design plan that the utility model adopted is that a kind of easily opened bottle cap comprises crown tip edge, caping, draw ring and riveting button.It is characterized in that caping outer periphery projection outer rim, be close to the inner ring of flange with the cooresponding draw ring of flange height, the base portion of draw ring is fixed by the riveting button of caping projection, and the line of cut base portion is near on the caping of flange.

It is little that above-mentioned design-calculated advantage is that line of cut accounts for the caping area, only accounts for the sixth of top cover area.The pulling force of draw ring concentrates on than on the small size, make draw back laborsaving, it is convenient to open, draw ring and protruding circle are at grade, just avoid mutual buckle and pulling bottle cap phenomenon in the handling process, the riveting button that caping fuses takes place with preventing to leak with the bottle explosion phenomenon, reaches easy to use, safe and reliable purpose.

Description of drawings

Fig. 1 is the utility model structure capping top view.

Fig. 2 is the back view of Fig. 1.

Fig. 3 is the longitudinal section of Fig. 1.

Fig. 4 is a running condition, when promptly bottle cap draws back, and scheme drawing.

Among the above-mentioned figure, 1 is locating point, and 2 is crown tip edge, and 3 is draw ring, and 4 are the riveting button, and 5 for isolating line, and 6 is top cover, and 7 is flange, and 8 is the draw ring crimping.

Embodiment describes

The utility model structure as shown in figures 1 and 3, crown tip edge is the general crown tooth 2 of international standard, adopts the process fuse to guarantee safety.Be the technology that the riveting button adopts and top cover fuses on the top cover 6, to increase the leak tightness of bottle cap.Most important for preventing the shape and the area that leak with bottle explosion line of cut 5, the folded area of parabola is little, relatively safety.The height of projection outer rim is less than or equal to the thickness of draw ring 3, so that caping keeps level, is convenient to deposit and transport.The line of cut of present embodiment is at area that caping the enclosed sixth less than the gross area of caping 6.The draw ring base portion is by tightening up mutually on the line of cut base portion that is covered in caping 6 and by riveting button 4, when the pull-up draw ring, can be laborsaving because the point of action of power is concentrated, and so that open conveniently, also increase airtightness of bottle cap.The base portion of draw ring covers on the line of cut, and the draw ring inner ring enlarges as far as possible, reserves more area to top cover, give and put up trade mark advertisement increase space, but keep draw ring can bear bigger pulling force again, so the draw ring back side is two-sided crimping, this structure also can prevent the incised wound finger.
