Abstract

The utility model discloses fake preventing sealing structure of a bottle mouth. The bottle mouth with a fake preventing pin is sealed by a bottle cover with a fake preventing pin window corresponding to the fake preventing pin. The utility model uses an outer cover 3 and an inner ring 6 with an inverse edge 8, wherein, the inner ring is embedded on the concave edge 9 of the bottle mouth and is provided with outer threads buckled with inner threads of an outer ring. The encapsulation of the bottle mouth of the utility model can be completed in pressing operation at one time, and the utility model simplifies the encapsulation process of the existing fake preventing bottles and increases encapsulation speeds.

Description

The Anti-forging for bottle mouth seal construction

The utility model belongs to bottle cap and makes the field.

Employing has the false proof bottle of false proof pin, and the special tectonic by bottle cap when opening bottle severs false proof pin, makes bottle can't be used to fake, and is a kind of effective method for anti-counterfeit.But supporting with it bottle cap generally all is made up of inner cap and enclosing cover two parts at present, when filling with liquid envelope bottle, and lid inner cap, and then crimping enclosing cover earlier.Like this, whole capping operation just divides in order to adorn inner cap and to adorn enclosing cover and carry out for twice, and this has influenced package speed to a certain extent.

A kind of Anti-forging for bottle mouth seal construction of the design of the purpose of this utility model makes it after the single job exterior and interior cover to be installed on the bottleneck when encapsulation, to improve encapsulation operation speed.

The purpose of this utility model is to realize by following design.

The Anti-forging for bottle mouth seal construction carries out the sealing of bottleneck at the bottle cap that has on the bottleneck of false proof pin with having with the corresponding false proof snib mouth of false proof pin, adopts an enclosing cover and the inner ring with edge; It is recessed along last that inner ring is embedded in bottleneck, the outside thread that inner ring has the negative thread with the outer ring to be interlocked.

After having adopted design as above, the bottleneck encapsulation can be finished in once pressing by operation, has improved encapsulation operation speed.

Description of drawings is as follows.

External view when Fig. 5 covers use for turning round of Fig. 3.

Fig. 6 is the External view of the vertical false proof pin scheme of the utility model.

Below in conjunction with accompanying drawing structure of the present utility model is done further detailed description.

In Fig. 1, can see, 1 is bottleneck, 2 for standing on the false proof pin on the bottle, and 3 is enclosing cover, and 4 is the false proof snib that covers outward, 5 is the bottleneck convex edge, 15 is tightening seal washer, and 6 is inner ring, and 7 are the sealing bed course, have down on the inner ring 6 and press along 8. inner rings that to be embedded in bottleneck recessed along in 9, the outside thread that has the negative thread with enclosing cover to be interlocked on the inner ring.

Before the envelope bottle, inner ring 6 revolves by screw thread to be put in enclosing cover 3, during the envelope bottle, enclosing cover and inner ring (need make the false proof snib of enclosing cover aim at Anti-forging for bottle mouth pin position) is pressed down together, the falling of inner ring pressed along 8, and to be embedded in bottleneck recessed along in 9, disposablely just finished false proof encapsulation.

During uncork, twist off false proof pin, inner ring 6 is fixed on the bottleneck, and enclosing cover upwards takes out along screw thread.

The profile of the false proof snib of enclosing cover can be varied, can be rectangle, arc etc., also can be wedge shape as shown in Figure 3, adopts wedge structure, when uncork, can utilize the window hypotenuse to sever false proof pin.

As shown in Figure 4, be write off safety, the glass of avoiding rupturing flies out and hurts sb.'s feelings, and can utilize the tearing strip of existing five preventing bottle caps to play the effect that flies pin of blocking.When reality is implemented, connect tearing strip 10 in the lower edge of enclosing cover, a little opening 11 is set in its position that covers false proof pin by existing routine techniques.

During uncork, the strap of pulling tearing earlier 12 breaks away from tearing strip and enclosing cover, and the turn enclosing cover clashes into false proof pin with false proof snib oral-lateral limit and makes it to fracture then, because the shield effect of tearing strip, disconnected pin can't fly out, and makes use of the present utility model safer.

Basic structure of the present utility model also is suitable for false proof pin 16 fully and is contained in situation on the bottleneck convex edge, and as shown in Figure 6, different just outer covering needn't be provided with false proof snib, is made as bayonet lock structure 13,14 and gets final product and change.

When reality was implemented, the multiple mode that is equal to can be adopted in the recessed edge on the bottle, pawl for example, rib ditch etc.
