Description

Bottle cap composite lining capable of reducing breakage rate of bottles and improving assembly stability

Technical Field

The utility model relates to a bottle lid inside lining especially relates to the compound inside lining of bottle lid that reduces the bottle breakage rate and improve assembly stability during assembly.

Background

Wine products are always serious disaster areas for counterfeiting. Among the anti-counterfeit bottle caps for wine products, there is a bottle cap liner formed by compounding plastic and metal, and the bottle cap liner is arranged on the inner side of a plastic liner main body and provided with a metal anti-picking ring. The bottle cap with the inner liner has the advantages that once the bottle neck is mounted, the metal anti-prying ring is connected with the bottle neck into a whole, and the metal anti-prying ring is difficult to separate from the bottle neck by using a common knife prying and baking mode. Under the condition that the metal anti-prying ring cannot be taken away, a counterfeiter cannot utilize the recovered original wine bottle to fill fake wine and then can prepare a fake bottle cap to make fake.

Although the lining has the anti-counterfeiting advantage, the lining also has certain defects. Because existing bottles are basically made of glass and ceramic materials, the reverse buckle of the metal tamper-proof ring can cause a considerable part of the buckle to bite off the locking collar of the bottle due to direct extrusion of two hard materials when the metal buckle slides over the locking collar of the bottle neck, so that the breakage rate of the bottle is increased. Secondly, between the back-off of metal pick-proof ring and the bottleneck, because of the complex reason, there is certain clearance usually, when the clearance is slightly bigger, can lead to the bottle lid to produce comparatively obvious rocking.

SUMMERY OF THE UTILITY MODEL

For solving the problem that exists among the prior art, the utility model provides a compound inside lining of new bottle lid can make the breakage rate of bottle reduce, and can improve the stability of assembly.

The technical scheme of the utility model as follows:

a composite liner for a bottle cap for reducing breakage rate of a bottle and improving assembly stability, comprising: the bottle neck, the inside lining, metal pick-proof ring, bottle neck and inside lining fixed connection, metal pick-proof ring fixed connection is inside the inside lining.

Wherein, the outer side of the bottle mouth is provided with a thread.

Wherein, the inner side of the lining is provided with a lining anti-rotation rib.

Wherein, the inner side of the metal anti-prying ring is provided with a reverse buckle.

Wherein, the inner side of the metal anti-prying ring is provided with a plastic buffer layer.

Wherein, the plastic buffer layer is attached to the inner side of the metal anti-prying ring.

The beneficial effects of the utility model are as follows:

after the plastic buffer layer is arranged on the inner side of the metal anti-prying ring, when the bottle cap is pressed on the bottle neck, because the plastic buffer layer is attached to the inner side of the reverse buckle of the metal anti-prying ring, the metal reverse buckle does not directly extrude the bottle neck locking hoop in the process of sliding through the bottle neck, the plastic buffer layer between the metal reverse buckle and the bottle neck locking hoop increases the contact surface with the bottle neck locking hoop through deformation, the extrusion force of the reverse buckle and the locking hoop is dispersed, and the breakage rate of the bottle is reduced. And after the back-off slides over the locking hoop, the plastic buffer layer is released after extrusion, so that the gap between the back-off and the bottle neck can be filled to a certain extent, the composite lining of the bottle cap can tightly hold the bottle neck, and the shaking of the bottle cap is reduced.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in figures 1, 2, 3, 4, 5. A composite liner for a bottle cap for reducing breakage rate of a bottle and improving assembly stability, comprising: bottle neck 1, inside lining 2, metal pick-proof ring 3, bottle neck 1, inside lining 2 fixed connection, the outside of bottle neck 1 is equipped with bottle neck screw thread 11, and the inboard of inside lining 2 is equipped with inside lining

anti-rotation rib

21, 3 fixed connection of metal pick-proof ring are equipped with back-off 31 in inside lining 2 inboard, a plastic buffer layer 32 has still been put to 3 inboard of metal pick-proof ring, the shape of plastic buffer layer 32 is identical with the inner structure of metal pick-proof ring 3, makes its laminating be in the inner wall of metal pick-proof ring 3 and the inboard of back-off 31.

The bottle neck corresponding to the utility model is made of glass or ceramic material. As shown in fig. 6, includes: a bottle neck 4, a locking collar 41 and a bottle neck anti-rotation rib 42.

The utility model provides a when the bottleneck is gone up to the compound inside lining dress of bottle lid that reduces bottle breakage rate and improve assembly stability, by the top of bottleneck 4 is impressed, metal pick-proof ring 3 is at the in-process that slips bottleneck locking hoop 41, because the inboard cladding of 31 of the back-off of metal pick-proof ring 3 has plastic buffer layer 32, makes the direct extrusion of two kinds of rigid material originally, has become and elastic plastic material's extrusion. In addition, because the camber of the reverse buckle 31 is different from that of the locking collar 41 during actual manufacture, the contact between the two is theoretically only one point when the two are actually contacted, and the possibility of breaking the bottle is high because the squeezing force is concentrated. After the plastic buffer layer 32 is provided, when the inverted buckle 31 slides over the locking collar 41, the force of extrusion is no longer concentrated on one point but dispersed on one surface around the extrusion point by the deformation of the buffer layer 32, so that the probability of bottle breakage is greatly reduced. Further, for assembly and tolerance in actual manufacturing, the inner diameter of the reverse buckle 31 is usually larger than the outer diameter of the neck 4 (if equal to the outer diameter of the neck 4, the reverse buckle 31 needs to expand outward greatly during assembly, which results in difficulty in pressing down and a large breakage rate of the bottle), and after assembly, the gap between the two will cause the liner 2 to shake greatly without the plastic buffer layer 32. In the case of the plastic buffer layer 32, after the inverted buckle 31 slides over the locking collar 41, the deformed part of the plastic buffer layer 32, which is generated by compression in the process of sliding over the locking collar 41, is recovered, so that the gap between the inverted buckle 31 and the bottleneck 4 can be filled, and the stability of the liner 2 on the bottleneck 4 is improved.

The bottle neck 1, the inner liner 2, the metal anti-prying ring 3 and the plastic buffer layer 32 can also be fixedly connected in the following mode: when the product is injected, the metal anti-prying ring 3 is placed into a mold cavity of an injection mold, the bottle neck 1, the lining 2 and the plastic buffer layer 32 are connected into a whole in a one-step molding mode, and the lining 2 and the plastic buffer layer 32 are respectively coated on the outer side and the inner side of the metal anti-prying ring 3. As shown in fig. 7.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
