Abstract

The utility model discloses a threaded bottle stopper comprising an upper part with the TPR material on the surface and a lower part with the PP material on the surface, wherein, the upper part is provided with a threaded structure matching with the tolerance of the bottle mouth aperture. The threaded bottle stopper disclosed by the utility model has the advantages of simple structure, good sealing performance, and popularization and application facilitation.

Description

The screw thread bottle stopper

Technical field

The utility model provides a kind of bottle stopper, specifically is a kind of screw thread bottle stopper.

Background technology

The bottle stopper material of Packaging Bottle class employing at present, pattern is various; But since the bottleneck bore of pottery bottle when firing positive and negative deviation bigger, general material anti-fatigue performance is limited, of long duration will occur leaking the wine phenomenon, so all the time, the bottle stopper problem of pottery bottle all is not well solved.

The bottle stopper of existing pottery bottle has wooden bottle stopper, and when not keeping flat for a long time or putting upside down, wooden bottle stopper can shrink, and causes sealing effectiveness bad, thereby can influence the quality of wine.And the general anti-fatigue performance of the bottle stopper of glue system is poor, and easy deformation of long duration can be leaked wine, and perhaps material is too hard, lacks flexibility, and is inconvenient to use.

Current, a kind of thermoplastic rubber TPR (Thermoplastic Rubber) has appearred, claim thermoplastic elastomer again.Thermoplastic rubber TPR is a kind of High molecular material that has thermoset rubber and thermoplastic plastic two specific characters concurrently, thermoplastic rubber has two polymer phases that disperse mutually, under normal serviceability temperature, one is fluid (when temperature is higher than its Tg-glass temperature) mutually, another is solid (be lower than its Tg or equal Tg in temperature) mutually, and has mutual action between the two-phase.Thermoplastic rubber TPR shows caoutchouc elasticity at normal temperatures, at high temperature again can plasticizing forming, both had the mechanical property and the in-use performance that are similar to rubber, and can resemble again and process and reclaim the thermoplastic plastic.TPR has the high resiliency of rubber, high strength, and high resilience, but have the feature of injection moulding processing again, have environment-protecting asepsis safety, soft-touch, weather resisting property, fatigue resistance and temperature tolerance, advantage such as processing characteristics is superior.

The utility model content

At the defective that prior art exists, the utility model provides a kind of screw thread bottle stopper in conjunction with the advantage of new material TPR, and is simple in structure, good seal performance, and can be convenient to make.

The technical solution adopted in the utility model is, a kind of screw thread bottle stopper comprises the lower part of surface for the top of TPR material and PP material, and described top is provided with the helicitic texture that cooperates with the bottleneck bore.

As preferred version, the top of described screw thread bottle stopper is provided with eyelet hole, wherein is with stay cord.

The utility model adopts basis material coating and bondings such as TPR material and PP, the bottom is divided into the PP material, and top is divided into coating TPR material, does the screw thread effect above the TPR material, played the leakproof effect, drinks through one enclose stop after fully with the outside air isolation.

During use, the screw thread bottle stopper vertically inserted in the bottleneck get final product.During unlatching, the stay cord that only needs to scratch in the eyelet hole can conveniently be opened.

Screw thread bottle stopper described in the utility model is a kind of simple in structure, and good airproof performance and bottle stopper easy to utilize after test repeatedly, can adapt to the bore of positive and negative deviation at ± 0.4MM.

The specific embodiment

The described screw thread bottle stopper 2 of embodiment is to be made by the lower part 4 of the top 3 coating PP materials of TPR material, and the Zhou Jing on the top 3 of described TPR material is provided with helicitic texture 5.And the top is provided with eyelet hole 6, wherein is installed with stay cord 7.In use, in the bottleneck with screw thread bottle stopper 2 vertical insertion bottles 1.Wherein the leakproof effect has been played by the bore engagement of the helicitic texture and the bottle 1 in its outside in the top 3 of TPR material.The lower part 4 of PP material is positioned at bottle.When needs take out bottle stopper, fasten stay cord with hand and firmly upwards pull out i.e. unlatching, convenient and swift.

Claims

1, a kind of screw thread bottle stopper is characterized in that, comprises the lower part of surface for the top of TPR material and PP material, and described top is provided with the helicitic texture that cooperates with the bottleneck bore.

2, according to the described screw thread bottle stopper of claim 1, it is characterized in that the top of described screw thread bottle stopper is provided with eyelet hole, wherein be with stay cord.
