Description

Large caliber push-out reopen type anti-counterfeiting wine bottle cap

Technical field

The utility model relates to a kind of large caliber push-out reopen type anti-counterfeiting wine bottle cap, the manufacturing technology field that belongs to liquid container protecting and prevent reusable seal closure.

Background technology

Existing anti-forge wine bottle cap is more with the ejecting type structure, provide " a kind of novel bottle cap " as CN2887775, cover under the ectosome effect by internal connection and to eject, its outlet is because the indoor design restriction, general ejection height is short, and bore is little, and the liquid outlet style is single, and can restore again, antifalse effect is not obvious.And for example CN201089573 provides a kind of " heavy caliber ejected anti-fake bottle lid ", though this kind ejecting structure has strengthened the diameter that ejects the hole, but inside lacks inner cap, must reset into the home position after opening, otherwise remaining liq is easy to outflow, influenced antifalse effect after the recovery again, and the version of ejection piece inwall and conduit outer wall usefulness polygon spline, assembling during to the manufacturing brings difficulty, because polygon has a rigging position, non-any direction can be packed into, and easily caused by the external force effect to reverse off normal, cause fluid seepage.

Summary of the invention

The purpose of this utility model provides a kind of reasonable in design, and is easy to use, can effectively promote antifalse effect, simplifies the large caliber push-out reopen type anti-counterfeiting wine bottle cap of production and assembly operation.

The utility model is a large caliber push-out reopen type anti-counterfeiting wine bottle cap, comprise overcoat, place the inner cap, connection cover, the cover that link to each other successively in the overcoat from top to bottom, the top of overcoat is provided with the sheet that ejects of band point of connection, it is characterized in that ejecting the external diameter of the diameter of sheet greater than inner cap; Connection cover also is arranged with lead set outward, is provided with spiral-shaped guide in the lead set, and the top of middle cover is provided with the adapter sleeve of band opening spline groove, and the bottom of connection cover is provided with the helical pitch piece that is embedded in guide rail and the opening spline groove.

The top of described guide rail also can be provided with the non-return breach.

Top in the described overcoat also can be provided with the main gear muscle, the outer wall top of lead set be provided with cooperate with the main gear muscle by the transmission muscle.

The utility model compared with prior art has following outstanding advantage and good effect:

1, outside connection cover, sets up the lead set of band guide rail, make connection cover when overcoat and lead set rotate synchronously, can move on fast along guide rail, thereby bursting ejects sheet, exposes inner cap, rotates inner cap once more, will expose liquid outlet, liquid retains if once drink in addition, and the inner cap of can screwing on once more prevents that rubbish from entering liquid and preventing to evaporate.

2, adopt and to eject the version of the diameter of sheet, inner cap integral body is ejected and expose, thereby simplify the production and assembly operation, reduce manufacturing cost greater than the inner cap external diameter.

3, on the guide rail top of lead set the non-return breach is set, can makes the helical pitch piece on the connection cover move on to the track of back, top getaway on fast and slip into the non-return breach, thereby connection cover can't be resetted, so just played very significantly anti-fake effect.Can also come resetting just of control linkage lid with the position that changes the non-return breach according to customer requirement, can reset fully, in the middle of also can resetting to.

Fig. 3 is the decomposition texture semisectional view of each parts of the utility model;

Fig. 4 is the running condition design sketch of the utility model after opening.

Among the figure, 1 is overcoat, and 2 is inner cap, 3 is lead set, and 4 is connection cover, and 5 is middle cover, 6 is point of connection, and 7 for ejecting sheet, and 8 is the main gear muscle, 9 is the axial location button, and 10 is negative thread, and 11 is by the transmission muscle, 12 is the non-return breach, and 13 is guide rail, and 14 is outside thread, 15 is the helical pitch piece, and 16 is adapter sleeve, and 17 is opening spline groove.

The specific embodiment

The utility model places the inner cap 2, connection cover 4, the cover 5 that link to each other successively in the overcoat 1 from top to bottom mainly by overcoat 1, is sheathed on lead set 3 formations such as grade outside the connection cover 4; What the top of overcoat 1 was provided with band point of connection 6 ejects sheet 7, ejects the external diameter of the diameter of sheet 7 greater than inner cap 2, and the top in the overcoat 1 is provided with main gear muscle 8, and middle part and bottom are provided with the axial location button 9 of solid centring sleeve 5; Be provided with the spiral-shaped guide 13 of top band non-return breach 12 in the lead set 3, outer wall top be provided with cooperate with main gear muscle 8 by transmission muscle 11; The top of middle cover 5 is provided with the adapter sleeve 16 of band opening spline groove 17, and the bottom of connection cover 4 is provided with the helical pitch piece 15 that is embedded in guide rail 13 and the opening spline groove 17; Inner cap 2 is connected with outside thread 14 states by negative thread 10 surely with connection cover 4.Concrete installation step is as follows:

1, with mechanical equipment inner cap 2 is twisted or is pressed onto above the connection cover 4, negative thread 10 and outside thread 14 are coincide and put in place;

2, will finish helical pitch piece 15 on the assembly parts of first step aim in the opening spline groove 17 and the part of cover 5 upper connecting sleeve 16 be pressed into, with pneumatic press-loading device two parts are pressed onto the end fully again;

3, lead set 3 is set on the assembly parts of finishing second step, pressure and rotate counterclockwise lead set 3 a little then is to colliding with middle cover 5 planes;

4, the assembly parts that third step is finished is put into above the special fixture, put overcoat 1 then, pressurization and rotating jacket 1 slowly make being aimed at by transmission muscle 11 of main gear muscle 8 and lead set 3 outer walls on the overcoat 1, firmly be pressed onto the end then, make overcoat 1 interior axial location buckle 9 and fasten middle cover 5 fully.

During use, rotate counterclockwise overcoat 1, the main gear muscle 8 of inwall drives by transmission muscle 11, lead set 3 is rotated, because the helical pitch piece 15 on the connection cover 4 is in the guide rail 13 of lead set 3 with overcoat 1, and helical pitch piece 15 can not be rotated by the restriction of the opening spline groove 17 on the middle cover 5, be forced to rise along guide rail 13, break point of connection 6 on the overcoat 1 of top slowly so just makes to eject sheet 7 and separate with overcoat 1, and expose inner cap 2, can not rotate until overcoat 1.And then anticlockwise motion inner cap 2, because the mutual action of negative thread 10 and outside thread 14, inner cap 2 can slowly rise during rotation, to breaking away from connection cover 4, at this moment just can fall liquid by tilt container.Do not fallen as disposable, can inner cap 2 be put on the connection cover 2 again, clockwise direction rotates then, until twist motionless till.If clockwise direction rotating jacket 1 more now, because guide rail 13 tops are provided with cooresponding non-return breach 12, the track of the helical pitch piece 15 meeting getaways 13 on the connection cover 4 enters non-return breach 12, thereby connection cover 4 can't be resetted, i.e. inner cap 2 whole being exposed to above the overcoat 1.
