The utility model has the advantages of reasonable design, can effectively preserve does not contain antiseptic beverage, the appearance is pleasing to the eye simultaneously, can use repeatedly.
Description
Technical field
The utility model relates to a kind of bottle cap, and particularly a kind of Double layer bottle cap, is mainly used in glass beverage bottle.
Background technology
Current beverage is due to cost reason, and be adopt plastic bottle and plastic bottle closure to deposit mostly, the beverage deposited so then must add anti fouling composition, otherwise is just difficult to preserve, and the beverage adding anti fouling composition is unfavorable for health.
Also the beverage had adopts glass bottle to deposit, and configures crown cap simultaneously.In order to prevent bottle cap from getting rusty, be generally inside bottle cap, be coated with one deck anti-rust paint or add one deck plastic inner cap.Inner cap is coated with anti-rust paint and can makes to produce toxin in beverage, and independent one deck bottle cap also seems attractive in appearance not simultaneously.Add one deck plastic inner cap in crown cap, equally can affect the preservation of beverage, still will add anti fouling composition in the beverage; And add plastic inner cap complex process, need to fix with glue, cost is high, and after Long-Time Service, glue also easily comes off.
Utility model content
Technical problem to be solved in the utility model to overcome in prior art existing above-mentioned deficiency, and provide a kind of reasonable in design, can effectively prevent beverage from going bad, the Double layer bottle cap of good looking appearance.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of Double layer bottle cap, comprises body of the bottle lid, it is characterized in that: described body of the bottle lid comprises the enclosing cover and inner cap that make by anti-rust metal; The shape of described enclosing cover and inner cap is the cylinder of bottom opening; Described inner cap is inserted in enclosing cover inside, and the opening direction of inner cap is consistent with enclosing cover, and the bottom of inner cap and the bottom of enclosing cover are fixed; The sidewall of described inner cap is provided with negative thread, and the top of inner cap is provided with sealing means of bottleneck.The inner cap that anti-rust metal makes can not pollute corrosion beverage, has good preservation effect to the beverage not adding anti fouling composition.
The bottom of enclosing cover described in the utility model is provided with the crimping dug laterally; The bottom turnup laterally of described inner cap, and the crimping of enclosing cover is wrapped.Manufacture craft is simple, is fixed by the base crimping of inner cap and enclosing cover, difficult drop-off, cost-saving.
Sealing means of bottleneck described in the utility model is seal ring, and seal ring is inserted in inner cap top to be fixed.Seal ring and drinking bottle mouth are fitted, Leakage prevention.
Sealing means of bottleneck described in the utility model is the circle injecting glue groove that inner cap top is arranged, and is cast with food stage sealant in injecting glue groove.Environmentally-friendly sanitary more, simultaneously sealing means of bottleneck difficult drop-off, sealing effectiveness is better.Because glass bottle beverage can Reusability after finishing off, easily come off after long with the general seal ring time.
The outside face flat smooth of enclosing cover described in the utility model, the junction of enclosing cover side and end face is provided with circular arc chamfering.Profile is more attractive in appearance, and bottle cap coordinates the more aobvious top grade of beverage bottle of glass.
The material of enclosing cover described in the utility model is corrosion-resistant steel, and the material of inner cap is corrosion-resistant steel or stainless iron.Can effectively preserve not containing the beverage of anti fouling composition.
Enclosing cover described in the utility model and inner cap are by machine one-shot forming.Technique is simple, easy to operate, cost-saving.
The utility model compared with prior art, has following positive effect: reasonable in design, can effectively preserve not containing the beverage of anti fouling composition; Good looking appearance simultaneously, can Reusability.

Fig. 2 is the structural representation of the utility model inner cap.
Fig. 3 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail.
Embodiment:
See Fig. 1 ~ Fig. 2, the present embodiment comprises the enclosing cover 1 and inner cap 2 that make by corrosion-resistant steel, and enclosing cover 1 and inner cap 2 are the cylinder of bottom opening; It is inner that described inner cap 2 is inserted in enclosing cover 1, and the opening direction of inner cap 2 is consistent with enclosing cover 1, and the bottom of inner cap 2 and the bottom of enclosing cover 1 are fixed; The sidewall of described inner cap 2 is provided with negative thread 21, and the top of inner cap 2 is provided with sealing means of bottleneck 3.The inner cap 2 that corrosion-resistant steel makes can not pollute corrosion beverage, has good preservation effect to the beverage not adding anti fouling composition.
In the present embodiment, the bottom of enclosing cover 1 is provided with the crimping 11 dug laterally; Bottom 22 turnup laterally of described inner cap 2, and the crimping 11 of enclosing cover 1 is wrapped.Manufacture craft is simple, and the outward-dipping turnup in bottom 22 of inner cap 2 wraps the crimping 11 bottom enclosing cover 1, and this process once can be completed by machine, can be mass, without the need to fixing with glue, cost-saving.
In the present embodiment, sealing means of bottleneck 3 is the circle injecting glue groove 31 that inner cap 2 top is arranged, and is cast with food stage sealant 32 in injecting glue groove 31.Environmentally-friendly sanitary more, simultaneously sealing means of bottleneck 3 difficult drop-off, sealing effectiveness is better.Because glass bottle beverage can Reusability after finishing off, easily come off after long with the general seal ring time.
In the present embodiment, the outside face flat smooth of enclosing cover 1, the junction of enclosing cover 1 side and end face is provided with circular arc chamfering 13.Profile is more attractive in appearance, and bottle cap coordinates the more aobvious top grade of beverage bottle of glass.
In the present embodiment, enclosing cover 1 and inner cap 2 are by machine one-shot forming.Technique is simple, easy to operate, cost-saving.
In the present embodiment, the material of enclosing cover 1 is corrosion-resistant steel, and the material of inner cap 2 is corrosion-resistant steel or stainless iron.Can effectively preserve not containing the beverage of anti fouling composition.
The bottle cap of the present embodiment, good looking appearance, coordinates glass beverage bottle to use, more aobvious top grade, simultaneously better to beverage preservation effect.After beverage finishes off, water tumbler Reusability can be worked as, antileaking, inner cap 2 difficult drop-off, very practical.
In addition, it should be noted that, the specific embodiment described in this specification sheets, as long as the undeclared concrete shape of its part and size, then this part can for any shape and size adapted with its structure; Meanwhile, the title that part is got also can be different.All equivalences of doing according to structure, feature and the principle described in the utility model inventional idea or simple change, be included in the protection domain of the utility model patent.
