Abstract

The utility model relates to a rotary fidelity bottle lid used for counterfeiting prevention and fidelity. The utility model is characterized in that the utility model is composed of an upper and lower lid structure, a core plug structure and a bottle mouth structure. A weak ring is composed of six intermittent joint blocks which are narrow, thin and open. When the core plug of the bottle is opened, after the weak ring is destroyed by force application, the core plug can be pulled out. The technique of cutting breakage in a torsion mode is adopted to break the weak ring by indirect force application, and the utility model has the advantages of time saving, labor saving, safety, reliability and favorable anti-counterfeiting and fidelity effect.

Description

Cap-rotating type fidelity bottle cap

The utility model relates to a kind of false proof, cap-rotating type fidelity bottle cap that fidelity is used.

Available in the market anti-false true-guaranteeing bottle cap is of a great variety, structure is different, but what the weakness ring of most bottle caps adopted is push-press type bending failure technology, weak ring is closing form, and is provided with singlely, and the destruction of weak ring is directly finishes with the hand application of force, time-consuming, effort, and be difficult to guarantee safety, adjustable is also relatively poor.For example: the anti-fake bottle lid of patent ZL95211654.5 is exactly like this.

The purpose of this utility model is exactly to design a kind of bottle cap that utilizes torsional mode fail in shear technology as the weakness ring, this weak ring need not directly just can be unlocked with the hand application of force arduously, both laborsaving, save time, and also safe and reliable, while does not lose false proof, the effect of fidelity.

With reference to the accompanying drawings the structure of cap-rotating type fidelity bottle cap described in the utility model is carried out detailed narration below.

Rotary bottle lid described in the utility model is made up of three parts: bottleneck structure, and the upper and lower cover structure, The core plug structure.

Bottleneck structure is to be made of bottleneck cylinder (21), bottleneck cylindrical center upper end be by round bottle oral pore (18) and Conical flask prostomum hole (20) consists of, and bottleneck cylinder upper end is outer to be a bottleneck along formation that is a bit larger tham the bottleneck cylinder Retaining ditch (16), bottleneck end face (17) are to be made of four projections that are evenly distributed on around the bottleneck hole, projection with Retaining ditch bottom surface is connected, and the depression that forms between the projection consists of four locking grooves (19), and the bottleneck cylindrical sleeve is existed On bottle (22) mouth, make bottleneck and bottleneck taper hole bottom connection.

The core plug structure is core plug (1) formation by an overcoat sealing column (2), the top of sealing column is a core plug edge (5) greater than the core plug, is four well-distributed backing blocks (4) at the core plug along following (3), size, the position is just in time corresponding with four back stop slots that the bottleneck end face constitutes, and the core plug has a rhombus positioning boss (10) along top (6), and handle (8) is linked to each other along top with the core plug by handle guiding arc (7), in order to increase the friction effect, establish a handle aperture (9) on the handle.The core plug that sealing column is being wrapped is inserted bottleneck hole and bottleneck taper hole, and the two be a transition fit, simultaneously, makes backing block align locking groove, insert wherein, to the core plug along following with in the contact of bottleneck end face, the core plug with bottle can not rotate mutually.

Center, lower cover (25) top (23) is a diamond hole (29), and the heating lower cover is enclosed within it outside bottleneck cylinder to uniform temperature, make its top diamond hole with handle guiding arc guide to, be inserted in the core plug, and be pressed on the bottle, to lower cover inner face (14) and core plug along top applying till.At this moment, the lower cover diamond hole is enclosed within on the corresponding rhombus gabarit of positioning boss (30) just, and lower cover and core plug can not rotate mutually.A Non-return ring (24) is arranged, because the effect of bottleneck cambered surface, is against in the bottleneck retaining ditch for being inclined upwardly tightly from downward-sloping upset in the lower cover.Lower cover hole (26) also contacts with bottleneck cylinder bearing fit.Lower cover can not withdraw from mutually with bottle.So far core plug, lower cover, bottle has been finished mutual location, connects, assembling.

Hd top face is encircled or be arranged on down to its weakness, connects piece (27) by six and constitute, or be arranged on top, the lower cover face of cylinder, connects piece (31) by six and constitute.Six connect piece and do not seal, and are interrupted, and are the circumference radiation-like, are symmetrically distributed, and the cross section is rectangle, and is not only narrow but also thin.Before it did not destroy, the core plug was to extract from bottleneck hole and bottleneck taper hole.

Loam cake (15) by loam cake knock hole (12) bearing fit, is enclosed within on the corresponding face of cylinder of lower cover.By loam cake positioning table (13) stop.Lock ring (11), by the semicircle scrobicular ring that covers down and on semicircle bulge loop two parts of covering constitute.

For the anti-skidding straight burr groove (28) that outside lower cover, is carved with.

In the time will opening bottle cap, left hand is held bottle, the right hand is pulled up loam cake, hold lower cover straight burr groove section then, along or the anticlockwise motion lower cover, because of lower cover by diamond hole, the rhombus gabarit of core plug positioning boss, and core plug backing block, the constraint of bottleneck locking groove etc. and can not rotating is so be sheared disconnected and destroy once weak ring firmly slightly.Take away down tops, can extract the core plug, then bottle is unlocked.

The utility model design-calculated cap-rotating type fidelity Bottle cap structure is simple, reasonable in design, and what weak ring adopted is that torsional mode is sheared broken ring, and the destruction of weak ring is that adopt indirect finished with the hand application of force, has safety, and is laborsaving, and advantage such as save time.Weak ring adopts and does not seal, and is interrupted, and evenly arranges, form is the circumference radiation-like when destroying than closed laborsaving, good reliability.
