Abstract

The utility model discloses a winebottle cap, and is composed of a jacket tube, a cap port, a rotating cap and an internal plug, threads of which are arranged on the cap port. The threads matched with the cap ports are positioned in the rotating cap, which is fastened on the cap port through the threads. A middle cover extending to an end is arranged on the cap port, and a plurality of vertical protruding edges and at least a groove or opening are positioned on the external side of the middle cover. The groove and a cam matched with the protruding edges at the external side of the middle cover are arranged on the internal side of the middle cover. The internal side of the cover is provided with a vertical sand grip and a clamp piece on the bottle jack. The cam inside the cover is inclined to the cap port. For the technical proposal is adopted, the middle cover passing through the cap port is fastened with the cover, so that the welding procedure and the produced fragments are avoided, and the rate of finished products is promoted. In addition, the cam inside the cover is inclined to the cap port, so that the middle cover is only required to be inserted into the groove or the opening in the cover.

Description

A kind of bottle lid

Technical field

The utility model relates to a kind of bottle cap, especially a kind of bottle lid.

Background technology

At present, the kind of bottle lid is a lot, wherein more common a kind of bottle lid comprises an overcoat, with overcoat bonded assembly lid mouth, interior plug and swivelling cover in the lid mouth, interior plug portion to overcoat to extension, be plugged with and ball valve, mozzle interior, the external cylindrical surface of lid mouth is provided with screw thread, swivelling cover is fixed on the lid mouth by screw thread, having in overcoat has a plurality of protruding longitudinally stupefiedly on the face, also have a plurality of fixture blocks on the same side face of the inside face of overcoat, and this kind bottle lid is fixed by the bottleneck of protruding stupefied and fixture block on the overcoat inside face and the bottle that is complementary with it.The overcoat of this bottle lid adopts ultrasonic welding usually with being connected of lid mouth, tends to produce a large amount of plastic flakes in welding process, and the cleaning in this bottle cap use has been brought difficulty, also can influence the yield rate of product simultaneously.The antifalsification of this in addition bottle lid is not high.

Summary of the invention

At the problems referred to above, the problem that the utility model quasi-solution is determined provides a kind of bottle lid clean, that antifalsification is good.

For achieving the above object, the utility model has adopted following technical scheme: a kind of bottle lid, it comprises the overcoat of tubulose, the lid mouth, swivelling cover and Nei Sai, described lid mouth is provided with screw thread, the inboard of described swivelling cover also is provided with the screw thread that is complementary with described lid mouth, described swivelling cover is fixed on the described lid mouth by screw thread, described lid mouth has the middle cover that Xiang Yiduan extends, have a plurality of vertically protruding stupefied in described on the cover outside, the cover outside also has at least one groove or opening in described, have on the inboard of described overcoat and the outer then protruding stupefied chase that is complementary of middle cover, with the projection that is complementary outside the middle cover, cooperate with the chase of described overcoat by the protruding stupefied of cover in described, make to overlap in the institute and radially fix with overcoat, groove or opening by cover in described cooperate with the projection of overcoat, make middle cover and overcoat axial restraint, described middle cover inboard also has and bottleneck is fixing vertical raised line and fixture block.

Above-mentioned bottle lid, the projection of described overcoat inboard is the inclined-plane to a lid mouthful direction.

Above-mentioned bottle lid, cover then also has a plurality of vertical detent projection near the outer of lid mouthful in described, described swivelling cover also has an anti-counterfeiting cover outward, described anti-counterfeiting cover comprises lid button and fracture circle, described fracture circle is connected with the lid point-like, described fracture circle inboard also has a plurality of vertical double wedges, and the double wedge of described fracture circle and middle cover projection are complementary, and restriction fracture circle relatively rotates with middle cover.

Above-mentioned bottle lid is characterized in that described Nei Sainei comprises ball valve and mozzle.

Owing to adopted technique scheme, middle cover and overcoat that the lid mouth is passed through are fixed, and have avoided welding sequence and have welded the fragment that produces, and can improve the yield rate of product.The projection of overcoat inboard is to the inclined-plane of lid mouthful direction in addition, in only needing cover be inserted into overcoat with, fall the groove or opening of cover in the place to the projection of overcoat in, can fix cover and overcoat in the lid, easy to assembly.At last, the anti-counterfeiting cover outside swivelling cover makes the bottle lid have anti-counterfeiting performance.

The specific embodiment

As Fig. 1, the utility model bottle lid shown in Figure 2 comprises the overcoat 1 of tubulose, lid mouth 2, swivelling cover 3 and Nei Sai 4, described lid mouth 2 is provided with screw thread, the inboard of described swivelling cover 3 also is provided with and described lid mouthful 2 screw threads that are complementary, described swivelling cover 3 is fixed on the described lid mouth 2 by screw thread, described lid mouth 2 has the middle cover 5 that Xiang Yiduan extends, have a plurality of vertical protruding stupefied 6 on cover 5 outsides in described, described vertically protruding stupefied 6 number can be decided according to the actual requirements, described middle cover 5 outsides also have four grooves or opening 7 (is opening in the accompanying drawing of present embodiment, can certainly be groove), in addition, the number of groove or opening 7 can be one or other numbers, have on the inboard of described overcoat 1 and middle cover 5 outer then protruding stupefied 6 chases that are complementary 8, the projection 9 that is complementary with the opening 7 in middle cover 5 outsides, cooperate with the chase 8 of described overcoat 1 by protruding stupefied 6 of cover 5 in described, make in the institute cover 5 radially fixing with overcoat 1, groove or opening 7 by cover 5 in described cooperate with the projection 9 of overcoat 1, cover 5 and overcoat 1 axial restraint in making, described in cover 5 inboards also have can with fixing vertical raised line 10 and the fixture block 11 of bottleneck.

As a kind of improved plan, the projection 9 of described overcoat 1 inboard is inclined-plane 12 (referring to Fig. 4) to lid mouthful 2 directions.

By said structure, middle cover 5 is radial and axial fixing with overcoat 1, has avoided the fragment of welding sequence and welding generation, and can improve the yield rate of product.In addition, the projection 9 of overcoat 1 inboard only needs middle cover 5 is inserted in the overcoat 1 to the inclined-plane of lid mouthful 2 directions, projection 9 to overcoat 1 falls in the groove or opening 7 of cover 5, can be fixing middle cover 5 and overcoat 1, saved the technology of conventional ultrasonic wave welding, easy to assembly.

Cover 5 then also has a plurality of vertical detent projection 13 near lid mouthfuls 2 outer in described, described swivelling cover 3 outer anti-counterfeiting covers 14 in addition, described anti-counterfeiting cover 14 comprises lid 15 and fracture circle 16, described fracture circle 16 is connected with lid 15 point-like, described fracture is enclosed 16 inboards and is also had a plurality of vertical double wedges 17, the double wedge 17 and middle cover 5 detent projection 13 of described fracture circle 16 are complementary, and restriction fracture circle 16 relatively rotates with middle cover 5.This structure must be connected fracture circle 16 when opening anti-counterfeiting cover 14 with the point-like of drawing together 15 of lids, played false proof effect

Further improve again as of the present utility model, comprise ball valve 18 and mozzle 19 in the described interior plug 4, the convenience that the bottle lid of assurance uses.
