Abstract

The utility model relates to a bottle cap, in particular to an anti-counterfeiting bottle cap with the automatic locking function. The bottle cap mainly consists of an upper part and a lower part which are all in columnar shape. The outer diameter of the upper part is smaller than the inner diameter of the lower part. The upper part is connected with the lower part through the connecting points which are circularly located. The upper part and the inside circle of the lower end of the lower part are respectively provided with three automatic locking drawing gears. When in use, the bottle cap is positioned on the bottle mouth to press the cap lid downwards; the convex part of the bottle mouth is seized by the automatic locking drawing gear in the bottle cap. The convex part and the automatic locking drawing gear are fixedly connected into a whole with good anti-counterfeiting function. The bottle cap is easy for installation and convenient for opening and safe in use.

Description

Anti-fake bottle lid

The utility model relates to a kind of bottle cap, especially a kind of anti-fake bottle lid with auto-lock function.

At present, a large amount of anti-fake bottle lids that use mainly contain porcelain bottle cap and crown cap, also have a spot of plastics anti-fake bottle lid, the porcelain anti-fake bottle lid burns with bottleneck and is one, need the junction of the two is firmly struck disconnected during unlatching, open Cover inside the bottle again, used bottle can not be recycled, reach false proof purpose with this, this false proof mode is because ceramic material fragility is big, poor toughness, and fracture place easily produces corner angle and cutting edge when knocking open, very easily hand is scratched, and its manufacturing process complexity, the cost height; The metal anti-fake bottle lid is to combine through mechanical presses and bottleneck, to reach false proof purpose, need use special tool during unlatching, and no instrument can't be opened bottle cap, and easily bottleneck is prized brokenly, opens difficulty, is awkward; The plastics anti-fake bottle lid is divided into two kinds substantially, a kind of is to connect the identical two-part anti-fake bottle lid up and down of external diameter by blank groove interval, connecting band in the middle of adopting, another kind is that several point of connection by circle distribution connect two parts up and down that external diameters vary in size, and the external diameter on top is less than the anti-fake bottle lid of the internal diameter of bottom, all be that its underpart and bottleneck cementation are reached false proof purpose as one when the two uses, the assembling trouble, the former is also because of outside connecting band is exposed to, the cutting edge that fractures easily scratches hand, poor stability.

The purpose of this utility model is intended to overcome the deficiency of above-mentioned prior art, and a kind of anti-fake bottle lid simple, that unlatching is convenient, safety is good that assembles is provided.

For achieving the above object, the utility model is achieved in that a kind of anti-fake bottle lid, mainly be dimerous by cylindrical circular upper and lower, its special character is, the external diameter on top is less than the internal diameter of bottom, point of connection by circle distribution between top and the bottom is connected, and is provided with three self-locking dops on the lower end inside circumference of top and bottom respectively at least.

Self-locking dop in the bottom is wedge.

The top on above-mentioned anti-fake bottle lid top can be a plane, also can be an arc-shaped curved surface, and the peripheral circumferential on top is provided with anti-skidding line.

Above-mentioned anti-skidding line can be processed into vertical straight line or other form.

Compared with the prior art the utility model is provided with corresponding self-locking dop owing in the upper and lower, only bottle cap need be pressed to bottleneck along bottleneck during use to get final product, easy to assembly; And periphery, bottle cap top is provided with the anti-skidding line with aesthetic feeling, and is firmly little, is easy to open, and opens the point of connection that the back fractureed and wrap in the bottom, do not expose, and hand can not scratched, scratches, and safety is good, and is convenient and practical.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a front view of the present utility model.

Fig. 2 is a upward view of the present utility model.

Fig. 3 is that the K-K of Fig. 2 is to cutaway view.

Fig. 4 is that the P-P of Fig. 3 is to cutaway view Amplified image.

With reference to Fig. 1, Fig. 2, Fig. 3, anti-fake bottle lid described in the utility model mainly is dimerous by cylindrical circular top 1 and bottom 2, the external diameter on top 1 is less than the internal diameter of bottom 2, point of connection 3 by circle distribution between top 1 and the bottom 2 is connected, at least be provided with three self-locking dops 4 on the lower end inside circumference on top 1, at least be provided with three self-locking dops 5 on the lower end inside circumference of bottom 2, self-locking dop (5) is a wedge, as shown in Figure 4.

With different aesthetic standards, a plane can be made in the top on this bottle cap top 1 according to demand, also can make an arc-shaped curved surface, or other some forms; Can design anti-skidding line 6 as required on the peripheral circumferential on top 1, in the present embodiment anti-skidding line 6 made vertical straight line with aesthetic feeling.

During assembling, only need bottle cap is placed on bottle mouth position, press to the neck of bottle then, cooresponding self-locking dop is just with the round platform pinning of an evagination of bottleneck bottle cap the upper and lower part in; During unlatching, execute a horizontal rotational force or apply a vertical pressure on bottle cap in the upper periphery of bottle cap, point of connection is fractureed, the upper and lower part is separated, take off top, the inner cap of opening bottle gets final product.

This bottle cap is easy to assembly, is easy to open, and simple to operate, anti-counterfeiting performance is good, and is safe in utilization, can be widely used in the bottled container of various uses.
