Abstract

The utility model relates to an anti-forging bottle top which is composed of an unsealing protection device and a bottle top body two parts. An opening edge of an external top and a cylinder at the lower part of an unsealing protective buckle are in fusion splicing. After an inner cap is screwed with a liquid leakage top, the opening edge of the liquid leakage top is placed on a circular concave stand in an inner cylinder, and then is carried out the fusion splicing and is placed in the external top. The lower part of the liquid leakage top is pressed with a support sleeve, and the lower part of the support sleeve is provided with a sealing ring. A snap ring and a ring-shaped negative are placed in the unsealing protective buckle. The annular negative and a cylinder of the unsealing protective buckle are in fusion splicing. Owing to simple assembly process, therefore, the cost is reduced, and the liquid leakage is hard.

Description

A kind of anti-fake bottle lid

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

Present common anti-fake bottle lid; generally all form by a plurality of component assemblys; the parts such as protection button, rack tube of uncapping are all made by metallic material; thereby screw thread or other modes are adopted in the connection between each part; adopt screw thread as the connection between enclosing cover and the protection button of uncapping; these connection modes increase overhours, the local undertighten of while bottleneck and bottle cap bonded assembly, leakage easily.

The purpose of this utility model provides a kind of without machine up, and all part is formed by plastic injection-moulded, improves structure, the simple anti-fake bottle lid of assembly technology.

The purpose of this utility model is achieved in that

A kind of anti-fake bottle lid; fender guard and bottle cap body two parts are formed by uncapping; the fender guard of uncapping comprises the protection button of uncapping; enclosing cover; clasp and annular egative film; bottle cap body comprises inner cap; the leakage lid; inner core; rack tube and seal ring; the opening edge of enclosing cover and the protection button welding of uncapping; after inner cap and leakage lid spin; the opening edge of leakage lid is put on the annular concave platform of inner core; and carry out welding; inner cap; the leakage lid; the inner core three makes the as a whole enclosing cover of putting into; under the annular external flange of rack tube, be inserted in seal ring; rack tube is inserted bottleneck; the annular external flange and the seal ring of carrying sleeve are pressed in above the bottleneck together, then the open end of leakage lid are pressed on the rack tube.Put into clasp in the annular groove in the protection button of uncapping and put into annular egative film at the cylinder end opening that the protection of uncapping is buckled, the cylinder fusing of margin that the annular egative film and the protection of uncapping are buckled connects.

Because all parts are formed by plastic injection-moulded, have improved structure simultaneously, thereby assembly technology simplifies, and reduced cost and easy-to-leak liquid not.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the birds-eye view of the utility model embodiment.

Fig. 2 is the section-drawing of the utility model embodiment.

The fender guard of uncapping of the present utility model comprises uncap protection button 1, enclosing cover 2, clasp 7 and annular egative film 8 among Fig. 1, Fig. 2.Bottle cap body comprises that there is annular groove the inside suitable for reading of inner cap 3, leakage lid 4, rack tube 5, inner core 6 and seal ring 10 inner cores 6, the lower end of leakage lid 4 is pressed in the annular groove of inner core 6, welding is carried out in contact position at the two, inner cap 3 covers 4, spins by simple microgroove with leakage, it is a concave surface that 4 internal upper parts are covered in leakage, around concave surface, open several holes, so that liquid flows out in the bottle.The bottom of rack tube 5 is inserted in the bottleneck, and top is inserted and is made in the leakage lid 4, and its annular external flange supports leakage lid 4.Downward tapered protrusion is arranged below the end face of inner cap, and it is tubaeform that 4 top openings are covered in leakage, and the two tapering is identical, when making inner cap 3 be pressed on the leakage lid 4, seals, and does not allow liquid flow out.The cylinder upper surface welding of the bottom surface of enclosing cover 2 and the protection button 1 of uncapping,, annular external flange is arranged at inner core 6 bottoms, supports the annular inward flange of the protection button 1 of uncapping.Clasp 7 outsides are cylindrical shape, the inside inner core be big mouthful downward tubaeform, it supports the outer annular flanges of inner core 6 above cylindrical shape, its inner core heads on the convex shoulder of bottleneck periphery, a fixation.Uncapping has the concave station of annular below the cylinder of protection button 1, and annular egative film 8 is put into this concave station, and annular egative film is buckled welding with uncapping to protect.

The process of uncapping is: downward curved disconnected the vertical part of the protection button of uncapping, cap with twisting off external 2 is detained 1 welding point with the protection of uncapping, and extracts enclosing cover 2 out, is the liquid of dress in the pourable bottle behind the inner cap 3 of outwarding winding.

Claims

1; a kind of anti-fake bottle lid; fender guard and bottle cap body two parts are formed by uncapping; the fender guard of uncapping comprises the protection button of uncapping; enclosing cover; clasp and annular egative film; bottle cap body comprises inner cap; the leakage lid; inner core; rack tube and seal ring; the opening edge and the welding above the cylinder of protecting bottom in the button of uncapping that it is characterized in that enclosing cover; after inner cap and leakage lid spin; the opening edge of leakage lid is put on the annular concave platform of inner core; and carry out welding; inner cap; the leakage lid; the inner core three makes the as a whole enclosing cover of putting into; under the annular external flange of rack tube, be inserted in seal ring; the open end of leakage lid is pressed on the rack tube; put into clasp in the annular groove in the protection button of uncapping; and put into annular egative film at the cylinder end opening of the protection button of uncapping, protect annular egative film the cylinder fusing of margin of buckleing to connect with uncapping.
