Abstract

The utility model relates to an easily opened bottle cover, belonging to the bottle cover of bottle type packaging containers. The existing easily opened bottle covers need pulling rings which are used for opening bottles, which not only increases the difficulty of processing, but also improves cost. The purpose of the utility model is to provide an easily opened bottle cover which does not need a pulling ring. The utility model is characterized in that a cover body is composed of a cover top and a cover neck, a cutting mark is processed between the cover top and the cover neck, and the diameter of the cover top is larger than that of the lug boss of the cover neck. When the utility model is used, a bottle opening neck is coated by the cover neck. When a bottle is opened, the bottle can be opened so long as the cover top is pushed by hand.

Description

Convenient bottle cap

The utility model relates to bottle bottle cap of class packing container, especially an easily opened bottle cap.

At present, in the prior art, easily opened bottle cap is more representational to be No. 89204052.1 disclosed technical schemes of Chinese patent.This technical scheme is that the end face in metal cap body is carved with the closed indentation that is easy to draw back, and rivets a metal draw ring, and when using, the part of lid end face indentation being surrounded with draw ring is drawn back and torn big uncork lid.This scheme has reached easy-to-draw uncaps and false proof effect, but must the riveted joint draw ring.Because the existence of draw ring not only makes the bottle cap end face not attractive in appearance, and increased the productive costs of bottle cap, in addition, the technique for riveting of draw ring is also complicated, and the difficulty that this has increased bottle cap processing again is the existing insurmountable problem of easily opened bottle cap.

The purpose of this utility model is at the existing in prior technology problem, and provides a kind of draw ring that do not need, the technical scheme that the easily opened bottle cap that production technology is simple, cost is low is new.

The technical program has been taked following measure: be made up of caping 1 and lid neck 3 with the lid that aluminum alloy materials is made, at the boundary of caping 1 with lid neck 3, be processed with and draw back, and described caping 1 is the boss of diameter greater than lid neck 3 diameters with the indentation 2 of separation caping 1 with lid neck 3.2 of the indentations of this programme are the cut-out traces that has four points of connection at least.In addition, the inner chamber at caping 1 also is equipped with packing seal 4.This bottle cap is to seal with the bottleneck neck with lid neck 3 in use, and during uncork, only with hand promotes caping 1, just caping 1 can be separated with lid neck 3 along indentation 2, and is extremely easy to use.

Use the easily opened bottle cap that this programme is made, because indentation is the cut-out trace that several point of connection are arranged, again between caping and lid neck, and caping is the boss of diameter greater than the lid neck, like this when uncork only with hand promote caping can uncork, therefore, no longer need to be provided with draw ring.Do not have the existence of draw ring, just make the production technology of bottle cap become simply, and cost reduces greatly.As seen, compared with prior art, its effect is extremely tangible.
