The utility model has the advantages of simple structure, convenient sealing and opening operation, reliable falsification prevention, etc. The utility model can be used by matching with plastic bottles. The utility model can preserve bottled objects which are not run out in a sealing way after the utility model is opened.

Description

Anti-fake bottle lid

A kind of anti-fake bottle lid belongs to packing container mouth piece technical field, is mainly used in the anti-counterfeit package of bottle of liquor and beverage.

In the prior art, along with the deep development of the activity of cracking down on counterfeit goods, various forms of anti-fake bottle lids continue to bring out.But with regard to the anti-fake bottle lid that can see in the market, be not that structure is complicated especially, encapsulation and open operation are all inconvenient, the cost height, and inconvenience is promoted; Be exactly that structure is too simple, in fact do not have anti-fake effect, therefore do not have practical value.Do not see as yet in addition have can with the matching used anti-fake bottle lid of plastic bottle.

It is a kind of relatively simple for structure that the purpose of this utility model is to provide, the encapsulation and open operation all more convenient, especially can with the supporting use of plastic bottle, the anti-fake bottle lid that anti-counterfeiting performance is good.

According to the physical property of plastics and the features of shape of bottleneck, at the subject matter that exists in the prior art, basic design of the present utility model is: this anti-fake bottle lid should be made of two discrete separately parts, some is to make the bottleneck dead ring of the prominent stalk ring of band in it and the groove loop fastener on the bottleneck outer wall when the pressurization in bottleneck of plug behind the bottle filling, and forever be in the same place with the bottleneck leak-tight joint, not destroying some can not open, be provided with the easy-open lid of band pull-tab in the ring, only need during unlatching this easy-open lid is drawn back pourable bottled thing; Be provided with in addition partly the enclosing cover of pressure ring for the top inwall, after inner cap installs this enclosing cover be spun on the whorl of bottleneck, its pressure ring lower edge is pressed on the last plane of easy-open lid in the inner cap that installs in advance, works as interior dress liquid like this and does not use up and screw enclosing cover again and still can play sealing function.Thereby realization design goal.

Anti-fake bottle lid described in the utility model is made of discrete separately enclosing cover 1 and inner cap 3, it is characterized in that this anti-fake bottle lid, semisphere and its top inner wall with an annulus under its above-mentioned enclosing cover 1 is also are provided with the pressure ring 2 that is connected as a single entity with it, and 3 of its above-mentioned inner caps are made up of the bottleneck dead ring 6 of prominent ridge ring in the pull-tab 4 that is connected as a single entity each other, easy-open lid 5 and the band from top to bottom and from inside to outside successively.The lower edge of this ring 6 is pressed on the last plane of above-mentioned easy-open lid 5 after the encapsulation.

Above-mentioned enclosing cover 1 hemisphere down with its outer wall of annulus be provided with vertical anti-skidding wrinkle, its inwall is provided with the negative thread that matches with external thread of bottleneck.

Outstanding advantage of the present utility model is relatively simple for structure, has only two big parts, and encapsulation and unlatching are all easy, only need draw back easy-open lid after enclosing cover screws off when especially opening to get final product.Owing to just closely be interlocked after the inner cap encapsulation with bottleneck, unless this inner cap some or bottleneck some are destroyed and could or else can restore the inner cap breakdown in case easy-open lid draws back, so content can't change, promptly false proof reliably.This anti-fake bottle lid especially is fit to and the supporting use of packing plastic bottle, the still salable preservation of the bottled thing of the part of not drinking after the unlatching.

Accompanying drawing is that scheme drawing cuts open in one of the utility model most preferred embodiment assembling back bulk shape structure office.

Further describe architectural feature of the present utility model as follows with most preferred embodiment by reference to the accompanying drawings: the inner cap 3 that is pressed into bottle mouth position during encapsulation is positioned at together the bottom and is embedded into bottleneck and with the easy open cover 5 of the pull-tab 4 that is positioned at innermost circle be positioned at outmost turns and the bottleneck dead ring 6 of the inwardly projecting ridge ring that band matches with groove ring on the bottleneck outer wall forms by being injection-moulded in food grade plastic, after inner cap 3 is built again by by spinning being injection molded under the hemispherical with having outside in the vertical anti-skidding wrinkle threaded annulus and its top inner wall have the enclosing cover 1 of a pressure ring 2 to encapsulate by food grade plastic on external thread of bottleneck.

Change as present embodiment:

1, raw MAT'L can change;

2, the connection mode of enclosing cover and bottleneck can change;

3, the height of the circle wall of easy-open lid and bottleneck dead ring all can suitably strengthen in the inner cap.

Claims (2)

1, a kind of anti-fake bottle lid, constitute by discrete separately enclosing cover [1] and inner cap [3], it is characterized in that this anti-fake bottle lid, semisphere and its top inner wall with an annulus under its above-mentioned enclosing cover [1] is also are provided with the pressure ring [2] that is connected as a single entity with it, and its above-mentioned inner cap [3] then is made up of the bottleneck dead ring [6] of prominent ridge ring in the pull-tab that is connected as a single entity each other [4], easy-open lid [5] and the band from top to bottom and from inside to outside successively.

2, anti-fake bottle lid according to claim 1, it is characterized in that under above-mentioned enclosing cover [1] hemisphere with its outer wall of annulus be provided with vertical anti-skidding wrinkle, its inwall is provided with the negative thread that matches with external thread of bottleneck.
