Detailed Description

The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which some, but not all embodiments of the utility model are shown. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 to 3, an isolated anti-aging bottle cap structure for white spirit comprises an upper cap 1, a bottle mouth 2, an inner plug 3, an inner cap 4, wherein the inner cap 4 is in interference fit with the upper cap 1, a first protruding part 5 is arranged on the side edge of the inner cap 4, a first concave part is arranged on the inner wall of the upper cap 1, the first protruding part 5 is mutually matched with the first concave part, the upper cap 1 and the inner cap 4 are connected to press the inner cap 4 into the upper cap 1 through pressure, so as to achieve the effect of fixed connection, at the moment, the first protruding part 5 can effectively prevent the phenomenon that the inner cap 4 is pressed deeply into the bottle mouth 2 and the lower part of the inner plug 3 to form a circular groove, a wine bottle is fixed in the groove, the connecting structure of the bottle mouth 2 and the wine bottle is known in the field, no more structures are introduced, an outlet for liquid to flow out is arranged in the inner plug 3, the bottle mouth 2 upper portion outside is equipped with the external screw thread, the inner wall of inner cup 4 is equipped with the internal screw thread, the external screw thread on the bottle mouth 2 and the internal screw thread in the inner cup 4 mutually support, the inner cup 4 inside is equipped with sealing washer 6, the external diameter of sealing washer 6 is the same with the internal diameter of inside plug 3 upper portion exit, the lower part thickness of sealing washer 6 is greater than upper portion thickness, at this moment when inner cup 4 and bottle mouth 2 screw up, even rock from top to bottom, the inside white spirit of beverage bottle also can only contact with inside plug 3 or inner cup 4, and can not contact with other materials, sealing washer 6 and inside plug 3 can adopt the plastics that ageing becomes embrittlement more difficult, such as PP or PE material, and other positions such as bottle mouth 2 etc. all can adopt the better material of transparency like bisphenol A class material, simultaneously the price of PE or PP material is relatively low for bisphenol A, also can suitably practice thrift the cost, more be fit for mass production.

Specifically, the inside of interior stopper 3 is equipped with the current limiting face 7, the middle arch of current limiting face 7, the current limiting face 7 side is connected with interior stopper 3 inner wall through connecting portion 8, and current limiting face 7 forms a plurality of arc liquid outlet 9 with interior stopper 3, sealing washer 6 lower part width is not less than liquid outlet 9's width, on the one hand prevent to pour out too much and cause the white spirit extravagant when pouring wine like this, simultaneously when inner cup 4 and bottle mouth 2 screw up, sealing washer 6 lower part and liquid outlet 9 contact, the lower part of sealing washer can block up liquid outlet 9 like this, even the beverage bottle is inverted, the white spirit also can be sealed by the cross-section that current limiting face 7 and sealing washer 6 formed, even can't be contacted with inner cup 4, at this moment inner cup 4 also can adopt bisphenol A class plastics, nevertheless consider inner cup 4 and sealing washer 6 to be integrated formation, if adopt different kinds of plastics, the degree of difficulty in production greatly increased, inner cup 4 still adopts PP or PE material in addition, take into account in the later stage processing can carry out the coating film and further deep processing on upper cup 1 and outer cup 10, consequently we have better performance to upper cup 1 and outer cup 10, better mechanical properties and better coating with the coating and better deep-processing performance, and better deep processing substrate processing.

Specifically, the level of the flow limiting surface 7 is lower than the level of the external thread on the bottle mouth 2, and in the cellaring process, we find that the specific part of the bottle cap where the fracture occurs is at the thread connection part, because people worry about the tightness of the bottle mouth, people always use more force to operate in the screwing process, so that the possibility of the fracture is higher, when the level of the flow limiting surface 7 is lower than the level of the external thread on the bottle mouth 2, white wine in the bottle is completely isolated below the thread level, the possibility that white wine contacts with plastic at the thread connection part is avoided, and the aging speed of the plastic used by the bottle cap is further reduced, so that the white wine can be cellared for a longer time without the phenomenon of the fracture of the bottle cap.

Specifically, the outside cover of 2 is equipped with enclosing cover 10, enclosing cover 10 is interference fit with 2 is chewed to the bottle, 2 outer walls are chewed to the bottle are equipped with second protruding portion 11, inside stopper 3 outer wall middle part is equipped with spacer 12, spacer 12 side is equipped with down and bends piece 13, when the bottle is chewed 2 with the bottle and the fixed in-process of stopper 3, the bottleneck of bottle can support on spacer 12 and bending piece 13, the enclosing cover 10 is established at the outside cover to the rethread for the outer wall of stopper 3 is closely hugged closely together with the bottle inner wall, further improved the leakproofness, stop the air and get into inside the bottle, make the white spirit can cellar for a longer time and not go bad.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.

Furthermore, it should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate embodiment, and that this description is provided for clarity only, and that the disclosure is not limited to the embodiments described in detail below, and that the embodiments described in the examples may be combined as appropriate to form other embodiments that will be apparent to those skilled in the art.
