Description

Plastic-aluminum tearing bottle lid

Technical field

The utility model relates to a kind of plastic-aluminum tearing bottle lid, belong to liquid container protecting with and prevent reusable seal closure manufacturing technology field.

Background technology

Traditional plastic-aluminum bottle lid is the mono-spiral-shaped structure, cause bottle to cover reusable and the generation counterfeit and shoddy goods, existing plastic-aluminum tearing anti-forge wine bottle cap mostly adopts complex structural designsization, increase pseudo-system difficulty, measures such as assembly technology complexity, its structure mainly is made of top-down aluminium lid, inner cap, connection cover, interior plug, trap etc., though have certain antifalse effect, can avoid the repeated usage of bottle lid, but, still have following defective from version:

1, aluminium lid is harder through the oxidation treatment rear surface, and its wall thickness is generally the 0.35-0.4 millimeter, and tear opening structure linearly after cutting is handled is hindered the hand accident and happened occasionally when tearing.

2, the connection cover and the employing ultrasonic welding of trapping easily generate plastic powders, bring great difficulty on dust collecting process.

Summary of the invention

The purpose of this utility model provides a kind of reasonable in design, and is easy to install and use, the plastic-aluminum tearing bottle lid that antifalse effect is good.

The utility model is a plastic-aluminum tearing bottle lid, comprise aluminium lid, place the interior inner cap of aluminium lid and trap, aluminium lid is provided with the tear opening of band tear string, be provided with negative thread in the inner cap, put down and be provided with the outside thread that is complementary with the inner cap negative thread, the top is provided with the pouring outlet, it is characterized in that the tear string on the described aluminium lid is a rolling formula wavy shaped configuration, the wall thickness of aluminium lid is the 0.15-0.25 millimeter; Trap and be one-piece construction.

Also can be provided with valve and Nei Sai in described the trapping.

Described middle part of trapping also can be provided with the rolling groove that is connected as a single entity with aluminium lid.

Cover in described and also can be provided with the rolling groove that is connected as a single entity with aluminium lid.

Also can be provided with and bottleneck leak free seal ring in the plug in described, make the fixing soft interior pad of valve.

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

1, the tear string on the aluminium lid is a rolling formula wavy shaped configuration, and the aluminium base is a pure aluminum material, and wall is thin easily to be drawn back, and does not hinder hand, has improved safety in utilization greatly.

2, connection cover of the prior art is connected as a single entity with trapping, becomes the single-piece lengthening and trap, make the structure reasonably optimizing that more becomes, cancelled ultrasonic welding process, assembly technology is simple, and can reduce plastic powders, improves the efficient of dedusting.

The utility model can with the supporting use of various bottles, especially can obviously improve the artistic grade and the cultural connotation of famous-brand and high-quality special wine, improve antifalse effect.

Fig. 1 is an integral structure semisectional view of the present utility model;

Fig. 2 is the decomposition texture semisectional view of each parts of the utility model.

Among the figure: 1 is aluminium lid, and 2 is inner cap, and 3 for trapping, and 4 is valve, 5 is interior plug, and 6 is rolling formula waveform tear string, and 7 is tear opening, and 8 is seal ring, 9 is negative thread, and 10 is small column, and 11,18 is the rolling groove, and 12 is seal ring, 13 are the protruding circle of sealing, and 14 is reinforced rib, and 15 is soft interior pad, and 16 is seal, 17 is outside thread, and 19 is thrust plate, and 20 is baffle teeth, 21 is sealing lip, and 22 is baffle teeth, and 23 are the pouring outlet.

The specific embodiment

The utility model mainly by aluminium lid 1, place the inner cap 2 in the aluminium lid 1 and trap 3, place the valve 4 of trapping in 3 and Nei Sai 5 etc. to constitute.Aluminium lid 1 is provided with the tear opening 7 of band rolling formula waveform tear string 6, and the wall thickness of aluminium lid 1 is the 0.15-0.25 millimeter; The small column 10, the negative thread 9 that are provided with seal ring 8 in the inner cap 2 from top to bottom, valve 4 is fixed, inner cap 2 outer rolling groove 11 and the baffle teeths 22 that are connected as a single entity with aluminium lid 1 that are provided with; Trap the outside thread 17 that is provided with pouring outlet 23, seal 16 on 3 from top to bottom, is complementary with inner cap negative thread 9, sealing lip 21, the rolling groove 18 that is connected as a single entity with aluminium lid 1, trapping is provided with thrust plate 19 and the baffle teeth 20 that is complementary with the bottle mouth in 3; In plug be provided with from top to bottom on 5 band reinforced rib 14 the protruding circle 13 of sealing, soft in pad 15, with bottleneck leak free seal ring 12.

During assembling, aluminium lid 1 through blanking, stretching, tack, phosphatization, application, roll tear string 6, form a bottle cap towards technologies such as tear openings 7.Trap and 3 earlier thrust plate 19 is carried out tilting upward behind the flange, the direction of the direction that makes thrust plate 19 during with injection molded is opposite, 3 handstand will trap again on the table, valve 4 also stands upside down and puts into 3 inside of trapping, interior plug 5 also stood upside down to be pressed in 3 the sealing lip 21 of trapping, because the protruding circle 13 of the sealing of interior plug 5 is interference fit with 3 the sealing lip 21 of trapping, can not become flexible so interior plug 3 is pressed in 5 the sealing lip 21 of trapping, also can not fall down easily, trapping this moment 3 is linked to be a little integral body with valve 4, interior plug 5.It is 3 on the table upright to trap, inner cap 2 vertically pressed to trap 3, because the negative thread 9 in the inner cap 2 is complementary with the outside thread 17 of trapping in 3, inner cap 2 with trap 3 can not be pulled out do not have yet very big loosening, seal ring 8 in the inner cap 2 is interference fit with the seal of 3 the tops of trapping, and the small column 10 in the inner cap 2 withstands valve 4.Soft interior pad 15 in the interior plug 5 has very big deformation coefficient, so the gap error that inner cap 2 press-fits in the process can automatically adjust by pad 15 in soft, valve 4 does not have sound of movement all the time, and each plastic was assembled and finished this moment.Aluminium lid 1 handstand is placed on the desktop, the whole handstand of the plastic of having assembled put into aluminium lid 1, plastic-aluminum spare is placed in the anchor clamps of gauge lathe special use, inner cap 2 is respectively equipped with a

rolling groove

11,18 in 3 with trapping, instrument is adjusted back two edge knurling process and is carried out together, aluminium lid and whole plastic are connected as a single entity, and rolling back plastic well pulls out to come out in aluminium lid 1.Because the baffle teeth 20 of trapping in 3 is complementary with spline groove in the bottle, the spline circle of thrust plate 19 and bottleneck is complementary, so whole bottle cap can not be spinned, can not be pulled out after plastic is fixed on the bottleneck.

During use, pull the tear opening 7 in the aluminium lid 1, tear opening 7 is drawn back along the tear string 6 of rolling formula wavy shaped configuration, and this moment, whole aluminium lid 1 single-piece outward appearance was destroyed, and the first half and inner cap 2 are connected as a single entity.Left-hand revolution aluminium lid 1, because all there is baffle teeth 22 at the two ends up and down of inner cap 2 outer rolling grooves 11, aluminium lid 1 because aluminium lid is very soft, has formed the baffle teeth that is complementary with inner cap naturally in the rolling process, so inner cap 2 also is rotated in the time of left-hand revolution aluminium lid 1, whole bottle cap is opened.When bottle tilted, wine liquid exported 23 from 3 the pouring of trapping and flows out, and clickwise inner cap 2 when not using, the small column 10 in the inner cap 2 are again with valve 4 diebacks, and wine liquid can not be given vent to anger and avoided repetition and waste, improves the quality of drinking.
