Description

A kind of bottle cap

The utility model relates to a kind of bottle cap.

Existing bottle cap generally all is to adopt to be threaded, in case just be not easy to seal again after opening, especially as smells such as sesame oil, essence, drinks, the gasoline liquid faster that volatilizees, in case the smell volatilization, will influence the quality of product, perhaps surrounding environment be produced and pollute.In addition, in case liquid is sold by can again, the user will be beyond recognition, and therefore usurp the famous brand container and make and sell the incident of fake wine, false wet goods liquid product and occur repeatedly.

At the problems referred to above, after the purpose of this utility model provides a kind of Kaifeng, on assurance leak free basis, can open use repeatedly, and have anti-fraud functional bottle cap.

To achieve these goals, the utility model is taked following design: a kind of bottle cap, it comprises loam cake and lower cover, it is characterized in that: on described, between the lower cover corresponding be provided with work in coordination on, lower convex ring and in, outer bulge loop, the circumference of described loam cake is provided with the fin of extracting described loam cake, described lower cover center has one and breaks lid for a short time off with the fingers and thumb by thin-walled and described lower cover bonded assembly, described lower cover bottom has the interior ring and the outer shroud that is enclosed within described bottle body and bottleneck that insert bottle body and bottleneck, and the bottom of described lower cover outer shroud has the barb-like inward flange of a circle and described bottle body and bottleneck clamping.

The utility model is owing to take above design, it has the following advantages: 1, break lid because the utility model is provided with one for a short time off with the fingers and thumb by thin-walled and lower cover bonded assembly, when the product of full of liquid uses first, can shake and rotate breaking lid for a short time off with the fingers and thumb, it is separated with lower cover form a hole, thereby pour out liquid, and in a single day this hole forms, and can not restore.If the unprincipled fellow is arranged, to desire to utilize again bottle to charge into new liquid and sell, it can not be sealed this hole.Because the barb effect on the outer shroud of lower cover bottom if desire screws down bottle cap from bottle, is quite difficult, as uses tamper tool, will leave a trace on bottle.Therefore the utility model has been possessed to prevent the unprincipled fellow again can go out the function of sell-fake-products product.Simultaneously, it is also convenient to use than the tearing device for opening of prior art to break the use of lid for a short time off with the fingers and thumb.2, the utility model since on upper and lower cover correspondence be provided with upper and lower bulge loop, when break off with the fingers and thumb for a short time the lid be removed after, lid still can reach good sealing effectiveness.Simultaneously,, make the utility model under assurance leak free condition, can open repeatedly, and can directly extract loam cake and use, and need not rotate bottle cap because correspondence is provided with inside and outside bulge loop on upper and lower cover, very easy to use.The utility model is simple and practical, and has the anti-counterfeiting function, and it can cooperate with corresponding bottle body and bottleneck, is widely used in the packing of various liquid products.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 4 is the schematic top plan view of Fig. 3

As shown in Figure 1, the utility model is made by rubber-like materials such as plastics, and it comprises a loam cake 1 and a lower cover 2.As shown in Figure 2, a lower convex ring 3 is arranged in the loam cake 1, lower convex ring 3 can be with tapering up big and down small slightly, and the bottom of lower cover 2 forms an internal projecting ring 4 to convex.Loam cake 2 outside faces can be provided with circle fin 5 or other ridge, in order to upwards extracting loam cake 1.As shown in Figure 3, lower cover 2 tops have one and go up bulge loop 6, and the outside slyness in the top of last bulge loop 6 is routed up, and with lower convex ring 3 outsides that are enclosed within loam cake 1 easily, and overlap tightening seals with lower convex ring 3.As shown in Figure 3, Figure 4, be provided with one at last bulge loop 6 centers and break off with the fingers and thumb for a short time and cover 7, break off with the fingers and thumb for a short time and cover 7 bottoms and assume diamond in shape, it is connected with lower cover 2 by thin-walled.When breaking off with the fingers and thumb and rotating and break off with the fingers and thumb for a short time when covering 7, itself and lower cover 2 can be separated.As Fig. 1, shown in Figure 3, an outer bulge loop 8 with internal projecting ring 4 clampings that are arranged on loam cake 1 bottom is arranged at lower cover 2 middle parts, the bottom of lower cover 2 has 9 and outer shrouds 10 of ring in.Interior ring 9 can insert in the bottle body and bottleneck of desire use, and outer shroud 10 can tightly be enclosed within the bottle body and bottleneck outer wall.At this moment bottle body and bottleneck does not have screw thread, and is straight wall shape.In outer shroud 10 bottoms of lower cover 2, inwardly convex into the barb-like inward flange 11 of a circle, corresponding with it, on bottle body and bottleneck, have a circle step that is mated.Convenient for inserting bottle, a lead angle 12 is inwardly formed on interior ring 9 bottoms.

In the foregoing description, break for a short time that to cover 7 moulding can be of all kinds off with the fingers and thumb, being provided with of upper and lower bulge loop 6,3 that cooperates between the upper and lower cover 1,2 can be exchanged, and the inside and outside bulge loop 4,8 that cooperates between the upper and lower cover 3 also can be taked other clamping form.The shape at upper and lower cover 1,2 other positions also can change to some extent in addition, and these change and the improvement of style should not got rid of outside the protection domain of the utility model patent.

In the time of the utility model can, at first liquid is full of bottle, lower cover 2 is enclosed within on the bottle body and bottleneck, firmly press downwards, bottleneck inserts between the inner and

outer rings

9,10 of lower cover 2, because the elastic reaction of plastics, the barb 11 on the outer shroud 9 will pass through bottleneck, be stuck in below the step that is arranged on the bottleneck bottom, can not be pulled out again.Then loam cake 1 is enclosed within above the lower cover 2, to pressing down, makes lower convex ring cover 3 tightly in last bulge loop 6 with hand, internal projecting ring 4 is clamped on below the outer bulge loop 8.When the utility model uses, open loam cake 1, will break off with the fingers and thumb for a short time and cover 7 and screw down from lower cover 2, hole of formation promptly can be poured out liquid from hole on lower cover 2.
