Abstract

The utility model relates to a pull-down plastic anti-falsification bottle cover, comprising the upper cover of an inner cover with labyrinth seal, wherein, the bottom end of the upper cover is provided with a sealing ring which can be matched with the interference of the locking stand of the mouth of the bottle; the inner side of the end part of the sealing ring is manufactured and provided with a circular arc rib; the outer side is manufactured and provided with a pull handle; both sides of the circular arc rib section which is connected with the pull handle are manufactured and provided with gaps. The utility model which obviously enhances sealing performance has the advantages of easy fabrication, convenient opening and visible anti-falsification effect.

Description

Pull-down plastic anti-false cover

The utility model relates to a kind of plastic bottle closure, particularly a kind of pull-down plastics anti-fake bottle lid.

At present, for preventing to produce personation high-quality bottled product, originating firm generally adopts the special bottle cap that seals, and it is better that commonly used easily opening approaches the crown cap effect, but the cost height consumes a large amount of metallic materials, is difficult for applying.Existing plastic closures lid, alternative thin crown cap, low cost of manufacture, but sealing, ineffective security.It adopts helicitic texture and bottleneck sealing or is pressed into the interior interference hermetically-sealed construction of bottleneck, and the dismounting bottle cap is easy to, and bottle cap is not had damage, so can not be false proof.

The purpose of this utility model provides a kind of pull-down plastics anti-fake bottle lid, and it is easy to manufacture, and it is convenient to open, and antifalse effect is remarkable, obviously improves sealing property.

The purpose of this utility model is achieved in that this bottle cap comprises the loam cake that has the labyrinth packing inner cap, its loam cake bottom be provided with can with the seal ring of bottleneck locking platform interference fit, inboard, seal ring end is processed with the circular arc fin, the outside is processed with handle, and the both sides of the circular arc fin section of joining with handle are processed with breach.

Because the utility model adopts the ring structure that has the circular arc fin, substitute existing screw thread and tighten structure, so interference fit by seal ring and bottleneck locking platform, together with the labyrinth packing inner cap in the loam cake, obviously improve sealing property than existing plastic bottle closure, seal ring outside handle and inner arc fin linkage section both sides are processed with breach, do not influence the interference fit of seal ring and bottleneck locking interstation, open seal ring but help handle, bottle cap is opened easily.In case bottle cap is opened, the seal ring of bottle cap just is damaged, and repeated usage is forged bottled product so prevent opening effectively again.For preventing to forge bottle cap, also can on bottle cap, print additional anti-fake mark by tops, to show difference.But this bottle cap single injection-molded, so easy to manufacture, cost is low.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a kind of concrete structure scheme drawing of the present utility model.

Describe concrete structure of the present utility model in detail according to Fig. 1.This bottle cap comprises loam cake 1, seal ring 2, handle 3, the circular arc fin 5 that has the labyrinth packing inner cap.Wherein loam cake 1 is close with the structure of common plastics lid, and its bottom is provided with seal ring 2.The internal diameter of sealing circle 2 is slightly less than the external diameter of bottleneck locking platform, that is to say that seal ring 2 can carry out interference fit with bottleneck locking platform section and connect, and guarantees connection place leak free reliability.The inboard, end of seal ring 2 is processed with circular arc fin 5, and the outside is processed with handle 3, and the both sides of the circular arc fin section of joining with handle are processed with breach (as shown in Figure 1).For further strengthening imitative pseudo-measure, also can print additional imitative pseudo-mark at the top of loam cake 1 by the inscription rubbing means.This bottle cap utilizes the labyrinth packing inner cap in the loam cake 1 and can seal with the seal ring of bottleneck locking platform interference fit, obviously improves sealing property.

During use, firmly bottle cap is pressed into bottleneck and gets final product.When opening bottle cap, the pulling handle 3 from bottom to top, with the handle 3 circular arc fin sections of joining, just draw back along breach 4 places, make seal ring 2 global shape breakages, are easy to open bottle cap, and bottle cap is once unlatching, and breach 4 just ruptures, so can prevent repeated usage effectively.

Claims

1, a kind of pull-down plastics anti-counterfeiting cover, comprise the loam cake that has the labyrinth packing inner cap, it is characterized in that the loam cake bottom be provided with can with the seal ring of bottleneck locking platform interference fit, inboard, seal ring end is processed with the circular arc fin, the outside is processed with handle, and the both sides of the circular arc fin section of joining with handle are processed with breach.
