Abstract

The utility model discloses a gum cap of a thermally contracted wine bottle for preventing secondary use, comprising a generally cylindrical body and a tension bar embedded in the middle of the body in a surrounding way. One end of the tension bar exposes out of the body; and the inner wall of the body is provided with a plurality of grooves intersected with the lower bottom surface of the body. As the grooves fail to penetrate the body, the strength of the body is unlikely to decline too much, so phenomena such as avulsion in the processing process is prevented and low production rejection rate is ensured.

Description

The thermal contraction wine bottle rubber cap that anti-secondary uses

Technical field

The utility model relates to the thermal contraction wine bottle rubber cap that a kind of anti-secondary uses.

Background technology

Present various bottle of liquors, the thermal contraction Capsule that all can adopt anti-secondary to use usually plays anti-fake effect.This Capsule is to adopt membranaceous plastics to make, and heats after overlapping to the bottle cap, and thermal contraction can take place in its lower end, closely fits with body.On Capsule, can paste antifalsification label and prevent that secondary from using, but antifalsification label not necessarily can be destroyed when uncork, is repeated easily to use.

The patent No. is that the utility model patent of ZL200720199366.1 discloses a kind of anti-transfer wine bottle rubber cap, section at second of this Capsule and to be provided with the crack line, this crack line is the dotted line shape of interruption, similar stamp easily tear seam, stressed will being torn to pieces slightly when uncork.

But this crack line is with the whole perforation of Capsule, causes the strength degradation of plastic film, mistake takes place in packaging process easily tear.And in being heated to the operation of fitting with bottle cap, body, because plastics are met thermal contraction, have isolated part between the part aperture by tear fracture, cause a plurality of apertures to fuse, become bigger hole, product rejection rate is higher.

Summary of the invention

Technical problem to be solved in the utility model provides that a kind of intensity is higher, the low thermal contraction wine bottle rubber cap of condemnation factor in the heating process.

The purpose of this utility model is achieved in that

The thermal contraction wine bottle rubber cap that a kind of anti-secondary uses comprises: roughly be body cylindraceous, be embedded in the tie rod at described body middle part around ground, an end of described tie rod exposes at described external.Offer the complex trace groove on the inwall of described body, the bottom surface of this groove and described body intersects.

Described groove extends along the generatrix direction of described body.Described groove is positioned at the below of described tie rod.The length of described groove is 1/2～1/10 of described body height.

The degree of depth of described groove be described body thickness 50～90%.

Described groove is made up of a plurality of discontinuous each other pits, and each described pit is arranged successively along the bearing of trend of described groove.Spacing between the two adjacent described pits is less than the length of described pit on the bearing of trend of described groove.

On the inwall of described body, offer the described groove in 3 roads equally spacedly.

Because the utilization of technique scheme the utlity model has following advantage:

1, because groove does not penetrate body, so the intensity of body can not descend because having offered groove too much, so phenomenon such as seldom can occur tearing in the course of processing, the production condemnation factor is low.

2, owing to there is not through hole, therefore tighten in the operation in follow-up heating, the situation in big space is melted, is produced at the interval that can not take place as Capsule of the prior art between the through hole.Avoided the strength degradation that causes owing to heating process and scrapped.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is specifically described.

Embodiment 1:

As shown in Figure 1, the wine bottle rubber cap in the present embodiment comprises that mainly one roughly is body 1 cylindraceous, and the first fixing the linking forms this body 1 around the back by membranaceous plastic hoop.At the middle part of body 1, horizontally embedded in the form of a ring have a tie rod 2, and expose outside body 1 termination of this tie rod 2, after holding for the user tie rod drawn back, thereby body 1 is torn, and plays Kaifeng and prevent the effect that secondary uses.

As shown in Figures 1 and 2, below the tie rod 2, on the inwall of body 1, offer 3 road grooves 3 equally spacedly.This groove 3 extends vertically along the generatrix direction of body 1, and its lower end extends to the bottom surface of body 1 always intersects, the upper end then and between the tie rod 2 at interval a segment distance.This is because if groove 3 intersects with tie rod 2, then when drawing back tie rod 2, can tear downwards along groove 3, and can't play the effect of the Capsule level being torn along tie rod 2.

The degree of depth of groove 3 account for greatly body 1 plastic film thickness about 80%.The effect of groove 3 is to produce the lower part of intensity in the bottom of Capsule body 1, and when uncork, any operation that Capsule is done all can cause Capsule to be torn along groove 3 like this, and Capsule just can not be used again, and plays anti-fake effect.

If groove 3 is too shallow, then be not easy to be torn, may cause Capsule intactly to be covered to detach then and be used by secondary from bottle, can't play anti-fake effect.Therefore, to make the degree of depth of groove 3 surpass 1/2 of body 1 thickness at least.

In the present embodiment, the length of groove 3 accounts for 1/4 of body 1 height greatly.At the bottle of common size, this height generally is no more than 1/3 of Capsule body 1 height about 5～10 millimeter.

Accompanying drawing 3 has been expressed the shape of present embodiment further groove 3.Groove 3 in the present embodiment is made up of the mutual discontinuous pit 4 of multistage, these pits 4 are arranged successively along the bearing of trend of groove 3, all there is the unaltered part of a bit of thickness to separate between the per two adjacent pits 4, play the effect of reinforcement, and when tearing, because the spacing of these compartments less than the length of pit 4, therefore can not influence the effect of tearing, groove 3 still can be torn easily and be come.

Embodiment 2:

Present embodiment 2 is that with the difference of embodiment 1 groove 3 is continuous strip as shown in Figure 4.This shape is easier comparatively speaking tears, but intensity is then relatively poor.

Groove 3 can form by the scraper compacting.As if the mode that adopts cutter to draw, then be not easy to control the degree of depth of groove 3, also can't produce the dotted line shape that is adopted as among the embodiment 1.

From practical angle, three road grooves 3 are set has been enough to play good result of use.If want to extrude more multiple tracks groove 3, then need more scrapers are set, productive costs is higher.

As mentioned above, we are illustrated according to aim of the present utility model fully, but the utility model is not limited to the foregoing description and implementation method.The practitioner of correlative technology field can carry out different variations and enforcement in the scope of technological thought permission of the present utility model.
