Description

A kind of overall plastic six cover rotary type anti-counterfeiting wine bottle caps

Technical field

The utility model relates to a kind of overall plastic six cover rotary type anti-counterfeiting wine bottle caps, the manufacturing technology field that belongs to liquid container protecting and prevent reusable seal closure.

Background technology

Existing overall plastic rotary type anti-counterfeiting wine bottle cap generally all reaches false proof effect with quick-fried disconnected form, its structure mainly is made up of loam cake, inner cap, Cracked ring, middle cover, valve, interior plug, seven parts of trapping, and mainly have following defective in structure and use: 1, product parts quantity is various; 2, Cracked ring cooperates requirement high with middle cover, inner cap, and tooth is carried on the back in existence, skidding is serious; 3, be the mono-disposable anti-false, open the back and produce the waste plastic slice, thin piece.

Summary of the invention

The purpose of this utility model provides a kind of reasonable in design, and is easy to install and use, has permanent anti-fraud functional overall plastic six cover rotary type anti-counterfeiting wine bottle caps.

The utility model is a kind of overall plastic six cover rotary type anti-counterfeiting wine bottle caps, comprise the loam cake of built-in inner cap and trapping of built-in middle cover, place valve and Nei Sai in the cover, it is characterized in that being provided with in the loam cake spline muscle and back-off bottom sediment, the outer wall of inner cap is provided with the outer spline muscle that cooperates with spline muscle and back-off bottom sediment respectively and the groove that links closely; Be provided with negative thread and interior limiting tooth in the inner cap, the outer wall of middle cover is provided with outside thread and the outer limiting tooth that cooperates with negative thread and interior limiting tooth respectively; Top in trapping is provided with locating surface and interior spline muscle, and the bottom is provided with the barb bottom sediment of solid centring sleeve bottom, and the middle part of middle cover is provided with stationary plane and the outer spline muscle that cooperates with locating surface and interior spline muscle respectively; The bottom of middle cover also is provided with spline muscle and the thrust plate that cooperates with bottleneck.

Also can be provided with guide collar and following guide collar on the described valve, Nei Sainei is provided with guiding rib and the guide collar that cooperates with last guide collar and following guide collar respectively, the sense of motion of may command valve, valve can be up and down when making pouring, valve can play the effect that wine is recharged during not pouring, has stopped bottle cap and has been used once more.

The present invention compared with prior art has following outstanding advantage and good effect:

1, between inner cap and the middle cover on the basis that prior art is connected with a joggle by internal and external threads, the further cooperation by inside and outside limiting tooth, after inner cap and middle cover press-fit as gapped available hand be screwed to the position, this moment, limiting tooth was separated from each other, when opening,, can open smoothly because of the design of tooth angle degree.But when tightening once more, because the design of limiting tooth, be screwed to that inside and outside limiting tooth will bump mutually certain the time, motion will stop, and the inner cap end opening will expose like this, has reached false proof effect.The elastic module of the Plastic Parts when wherein assembling also plays conclusive effect to antifalse effect.Elastic module can carry out with the mode that press-fits, then compress and cover at 1 o'clock, the elastic module of screw thread dwindles greatly, thereby after being opened, the finished product lid can't directly be pressed into, the mode that must adopt hand to twist, and must be subjected to the prevention of limiting tooth when twisting, thus reach the antifalse effect that the slit occurs, play the effect whether identification was opened, just Guan Jian antifalse effect here embodies.

2, the inwall of trapping is provided with the spline muscle that cooperates with middle cover, suitable for reading have a locating surface, end opening has the back-off bottom sediment, after middle casing pressure installs, locating surface and back-off bottom sediment have been fixed middle cover, trap and such being engaged in of middle cover do not have under the situation of glass bottle, the single moulding that assembles just becomes as a whole, and non-loosening can be sayed.

The specific embodiment

The utility model mainly by the loam cake 1 of built-in inner cap 2 and built-in in cover 3 trap 6, place formations such as interior valve 4 of cover 3 and Nei Sai 5; Be provided with spline muscle 7 and back-off bottom sediment 8 in the loam cake 1, the outer wall of inner cap 2 is provided with the outer spline muscle 9 that cooperates with spline muscle 7 and back-off bottom sediment 8 respectively and the groove 12 that links closely; Be provided with negative thread 11 and interior limiting tooth 14 in the inner cap 2, the outer wall of middle cover 3 is provided with outside thread 16 and the outer limiting tooth 21 that cooperates with negative thread 11 and interior limiting tooth 14 respectively; The tops of trapping in 6 are provided with locating surface 17 and interior spline muscle 15, the bottom is provided with the barb bottom sediment 10 of solid centring sleeve 3 bottoms, the middle part of middle cover 3 is provided with stationary plane 18 and the outer spline muscle 22 that cooperates with locating surface 17 and interior spline muscle 15 respectively, and the bottom of middle cover 3 also is provided with spline muscle 20 and the thrust plate 19 that cooperates with bottleneck.Valve 4 is provided with guide collar 23 and following guide collar 24, is provided with the guiding rib 25 and the guide collar 13 that cooperate with last guide collar 23 and following guide collar 24 respectively in the interior plug 5.Concrete installation step is:

A, interior plug 5 is placed on the anchor clamps, puts into valve 4, cover 3 in putting in the above again, plug 5 overlaps with middle cover 3 in making, and the armrest plate pressing machine is carried out and is press-fited for the first time, forms internals integral body.

B, 6 be placed on the set anchor clamps trapping, put into the assembly that steps A assembles, craft or palm press are carried out and are press-fited for the second time, and trapping 6 becomes second integral body with assembly.

C, the assembly that step B is assembled are placed on the anchor clamps, utilize the palm press to be pressed into inner cap 2, are pressed into loam cake 1 for the second time again, and entire product is just assembled and finished like this.

One hand is held loam cake 1 and is carried out contrary formula rotation during use, inner cap 2 screw threads and middle cover 3 screw threads tensile force do with under, begin rotation and throw off inside and outside limiting

tooth

14,21, so just open product, liquid can therefrom overlap a mouth pouring district, 3 top and leak out; The screw thread of the screw thread of inner cap 2 and middle cover 3 is rotated motion in the cis rotary course, owing to limiting tooth design-calculated reason, the outer limiting tooth 21 of cover 3 is collided with the interior limiting tooth 14 of inner cap 2 in time certain, and motion stops, like this loam cake 1 and trap and just produce a space between 6.
