Description

Novel cassette screws out combination plastic-aluminum pilfer proof closure

(1) technical field:

The utility model relates to a kind of aluminium-plastic cap, and especially a kind of waist is provided with groove (or the open end of aluminum barrel is provided with the hoop antelabium), exposes antifalsification caution ring and irrecoverable novel cassette after the unlatching and screws out combination plastic-aluminum pilfer proof closure.

(2) background technology:

At present, on the market main adopt have cassette explosion, cassette to eject, aluminium-plastic caps such as cassette twists off, cassette back-out.But there is certain defective in these aluminium-plastic caps at aspects such as anti-counterfeiting performance, sealing property, unlatching performance, encapsulation performance, environmental-protecting performances.Such as:

Aspect anti-counterfeiting performance, after cassette explosion bottle cap is opened, the Cracked ring fracture; After cassette twisted off the bottle cap unlatching, aluminum barrel connected the some fracture; After cassette ejects the bottle cap unlatching, the fracture of top aluminum barrel; What adopt all is destructive anti-counterfeit, and after the unlatching, bottle cap is destroyed.

Aspect sealing property, it is gasket seal that cassette twists off the sealing means that ejects bottle cap and bottleneck with cassette, if the gasket compression amount is inconsistent, will cause Lou wine phenomenon.

Opening aspect of performance, after cassette explosion bottle cap is opened, the Cracked ring fracture can drop to the ground or the wine table on, cause pollution easily.Point fracture place of aluminum barrel company existed wedge angle to scratch the customer easily when cassette twisted off unlatching.When cassette ejects the bottle cap unlatching burst apart and hurt customer's eyes easily in part, aluminum barrel top.

Aspect encapsulation performance, cassette explosion bottle cap is in encapsulation process, and Cracked ring ruptures easily.Cassette twists off bottle cap in encapsulation process, and aluminum barrel connects some fracture easily.

Aspect environmental-protecting performance, it all is destructive anti-counterfeit that cassette explosion, cassette eject bottle cap, has aluminium matter or plastic material to break away from body of the bottle lid, is scattered in the environment, causes pollution, not environmental protection easily.

Cassette screw out aluminium-plastic cap at above aspect of performance all than more excellent, but its false proof ring intensity a little less than, with the assembling process of combination cover in, phenomenon (as shown in Figure 1) the assembling aluminum barrel difficulty of false proof ring distortion appears easily, efficient is lower, reject rate is higher.

The purpose of this utility model provides a kind of Anti-Counterfeit Identification Device of improvement, eliminates or alleviates problem in the above-mentioned existing technology of mentioning.

(3) summary of the invention:

The purpose of this utility model provides a kind of novel cassette with Anti-Counterfeit Identification Device and screws out combination plastic-aluminum pilfer proof closure.

Novel cassette screws out the combination pilfer proof closure, is made up of aluminum barrel 1, enclosing cover 2, combination cover 3, interior plug 4.It is characterized in that

1.. this bottle cap can increase liquid can not recharge device, glass bead 5.

2.. the doffing part of aluminum barrel comprises the impression 1-3 part that is arranged on doffing 1-2 top around the oral area and the neck of bottle.Also can adopt the hoop antelabium 1-4 of the open end of doffing 1-2 to replace impression 1-3 part.Can limit doffing 1-2 and produce axial motion with respect to combination cover 3.

3.. top cylinder 1-1 be arranged on the outside of enclosing cover 2 and with its flush fit, it is linked together, bottle cap prevents to produce circumferential rotation when opening.

4.. on the combination cover 3 groove 3-1 is set, the impression 1-3 on doffing 1-2 top partly is pressed into wherein, and combination cover 3 also is used to limit bottle cap and rotates with respect to the neck of bottle.

5.. on the false proof ring 2-1 of enclosing cover 2 groove 2-3 is set, the part that connects top cylinder 1-1 and doffing 1-2 is pressed into wherein.

6.. in the bottle lid opening process, the company's point 1-5 that connects top cylinder 1-1 and doffing 1-2 at first breaks, connect company's point 2-2 fracture of enclosing cover false proof ring 2-1 and enclosing cover the first half then, top cylinder 1-1 and doffing 1-2 are separated from, the false proof ring 2-1 of enclosing cover and the first half break away from, stay doffing part and leakage outside, this appreciiable indication shows that bottle cap is unlocked.When the bottle cap quilt was airtight again, the false proof ring 2-1 of enclosing cover separated top cylinder 1-1 and doffing 1-2.

Compared with the prior art the utility model has following good effect:

1.. owing on the false proof ring 2-1 of enclosing cover groove 2-3 is set, the part that connects top cylinder 1-1 and doffing 1-2 can be pressed into wherein;

2.. because combination cover 3 peripheral middle parts are provided with groove 3-1, the impression 1-3 part on doffing 1-2 top can be pressed into wherein (or the open end of aluminum barrel is provided with hoop antelabium 1-4), and aluminum barrel 1 is combined firmly with combination cover 3;

3.. because the latter half of enclosing cover 2 is provided with false proof ring 2-1, after bottle cap was opened, the false proof ring 2-1 of enclosing cover and the first half broke away from, and stayed doffing part and leakage outside, and antifalse effect is good.

4.. because the false proof ring 2-1 intensity that enclosing cover 2 the latter halfs are provided with is good, be not prone to the phenomenon that the false proof ring distortion causes (as shown in Figure 2) assembling aluminum barrel difficulty.

(4) description of drawings:

Now by example and with reference to description of drawings embodiment of the present utility model, wherein:

Fig. 1 is that the distortion of cassette back-out combination plastic-aluminum pilfer proof closure false proof ring causes assembling the scheme drawing of aluminum barrel difficulty.

Fig. 2 is that novel cassette screws out combination plastic-aluminum pilfer proof closure false proof ring and is not prone to the false proof ring distortion and causes assembling the scheme drawing of aluminum barrel difficulty.
