Abstract

The utility model provides a single structure overlapping plastic anti-theft bottle cap, which is composed of a bottle cap body and an anti-theft ring. The single structure overlapping plastic anti-theft bottle cap is characterized in that an overlapping annular leak proof ring which is molded and formed once with the other parts of the bottle cap is positioned at an inner wall on the top end of the bottle cap near by a top surface; the lower end of the bottle cap body is provided with tension reinforcing ribs which are formed once for connecting the anti-theft ring which can disengage from the bottle cap body; a plurality of bar-shaped convolutional tension lines are evenly distributed in the anti-theft ring. The utility model has the advantages of reasonable structural design, good sealing and leak proof performance, and safe and convenient operation; the single structure overlapping plastic anti-theft bottle cap can be widely used for the technical field of drinks, alcohol, medicine bottles, etc.

Description

Single structure eclipsed form antitheft plastic cap of bottle

The utility model relates to container cover, particularly a kind of single structure novel plastic anti-theft bottle cap.

At present popular on the market various beverages, drinks seal bottle cap, generally adopt the metal anti-theft bottle cap or anti-theft feature such as anti-false sign on bottle cap is annotated.Metal anti-theft bottle cap is characterized in sealing more firm, but there is the manufacturing process complexity in it, and equipment investment is big, at the bottom of the utilization rate of raw materials, and cost height, deficiency such as incised wound finger easily during use.Along with the continuous development of science and technology, there was a small amount of antitheft plastic cap of bottle to put on market in recent years.This bottle cap is after utilizing the injection machine injection mo(u)lding, though form by secondary processing cutting it on manufacturing process and productive costs thereof, remedied above-mentioned deficiency.But structurally because design is perfect inadequately, have poor sealing performance, product is subjected to bacterial contamination easily through secondary processing, can therefore cause the rotten too early deficiency that waits of beverage in the time of seriously.

The purpose of this utility model provides that a kind of technology that causes is simple, and the sealed against leakage performance is good, single structure eclipsed form antitheft plastic cap of bottle safe in utilization.

The purpose of this utility model is achieved by the following scheme: be provided with one with the single step moulded together eclipsed form ring-type leakproof circle of bottle cap other parts in the bottle cap top inner wall near the end face place, the lower end of the bottle cap once pulling force reinforced rib of moulding connects an anti-theft ring that can break away from bottle cap, is evenly distributed with some the wire line of pull that circles round on the inwall of this anti-theft ring.The inwall base that is positioned at anti-theft ring simultaneously is provided with also that one is long and the other is short vertical convex non-skid thread spaced apart.

The utility model is compared with the prior art: have reasonable in designly, technology is simple, and one-shot forming is sealed firmly, and the leakproof pollution-proof performance is good, the stock utilization height, and cost is low, and low price is safe in utilization, is easy to advantages such as popularization.Can be widely used in fields such as beverage, drinks, medicine bottle.

Below in conjunction with accompanying drawing the utility model is illustrated:

Fig. 1 is a structural representation of the present utility model.

As shown in Figure 1: constitute by bottle cap body and anti-theft ring two parts, bottle cap top inwall is near the end face place, be provided with one with the single step moulded together eclipsed form ring-type leakproof circle 1 of bottle cap remainder, the lower end of bottle cap is the pulling force reinforced rib 2 of moulding once, this reinforced rib anti-theft ring 4 that can break away from bottle cap of ining succession, adopt trapezium structure to make non-skid thread on this anti-theft ring outer wall, the inwall base that is positioned at anti-theft ring simultaneously is provided with that one is long and the other is short vertical convex non-skid thread 5 spaced apart with concave-convex sense.This bottle cap is to utilize the injection machine single injection-molded, can not guarantee to meet state health standards behind the various beverage packagings because of secondary processing pollutes.

Claims (2)

1, a kind of single structure eclipsed form antitheft plastic cap of bottle, constitute by bottle cap body and anti-theft ring, it is characterized in that: be positioned at bottle cap top inwall and be provided with one with the single step moulded together eclipsed form ring-type leakproof circle (1) of bottle cap body other parts near the end face place, the lower end of the bottle cap once pulling force reinforced rib (2) of moulding connects an anti-theft ring (4) that can break away from bottle cap, is evenly distributed with some the wire line of pull (3) that circles round on the inwall of this anti-theft ring (4).

2, anti-theft bottle cap according to claim 1 is characterized in that: the inwall base of anti-theft ring (4) is provided with also that one is long and the other is short vertical convex non-skid thread (5) spaced apart.
