Description

Twist-broken anti-fake bottle cap

Technical field

The utility model relates to anti-fake bottle lid technical field, especially a kind of twist-broken anti-fake bottle cap of metal lid assembling plastic inner cap.

Background technology

The utilization of anti-fake bottle lid in field of anti-counterfeit technology of metal case is long-standing.Existing metal case anti-fake bottle lid is generally divided into three kinds in the market: the first directly coordinates bottleneck for metal case, metal case can twist off thus reach false proof object, bottleneck and metal case friction during owing to opening, easily produce metal powder and affect its use; The second is that metal case coordinates complicated two or more plastics inner part, and metal case can twist off and reach false proof object, complex structure; The third is the plastic bottle closure that assembling is complete in metal case, and metal case only plays decoration function, and plastic bottle closure is close to the inner portion false proof, the various but complex structural designs of outward appearance.

Utility model content

Technical problem to be solved in the utility model is to provide that a kind of structure is simple, low cost of manufacture and the good twist-broken anti-fake bottle cap of antifalse effect.

The utility model solves the twist-broken anti-fake bottle cap that its technical matters adopts, comprise metal lid, plastic inner cap and bottleneck, described plastic inner cap has negative thread, described bottleneck has outside thread, described negative thread and outside thread match, described metal lid has a circle enclosing cover line of cut, metal lid is divided into enclosing cover top and enclosing cover bottom by described enclosing cover line of cut, and metal lid is in enclosing cover line of cut place frangibility; There is inner cap antiturning pitch described plastic inner cap periphery, and described metal lid has the enclosing cover antiturning pitch coordinated with described inner cap antiturning pitch, described metal lid envelopes described plastic inner cap; Described bottleneck there is the cambered outwards enclosing cover connected unit of a circle, to curls inward bottom described metal lid, the connected unit bottom surface of enclosing cover inner wrap portion and described enclosing cover connected unit.

Further, described inner cap antiturning pitch is positioned at periphery bottom described plastic inner cap, and described enclosing cover antiturning pitch is positioned at bottom, described enclosing cover top.

Further, described metal lid has false proof muscle, described false proof muscle is inwardly extruded by the metal lid that described enclosing cover line of cut position is corresponding and is formed.

Further, described enclosing cover antiturning pitch is trapezoidal strip.

Further, described enclosing cover antiturning pitch reason metal lid sidewall inwardly extrudes formation.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.It should be noted that at this, the explanation for these embodiments understands the utility model for helping, but does not form restriction of the present utility model.

As shown in Figures 1 to 6, the utility model comprises metal lid 1, plastic inner cap 2 and bottleneck 3, and described plastic inner cap 2 has negative thread 21, and described bottleneck 3 has outside thread 31, described negative thread 21 and outside thread 31 match, and realize the sealing locking function between plastic inner cap 2 and bottleneck 3; Described metal lid 1 has a circle enclosing cover line of cut 13, metal lid 1 is divided into enclosing cover top 11 and enclosing cover bottom 12 by described enclosing cover line of cut 13, and metal lid 1 is in enclosing cover line of cut 13 place frangibility; There is inner cap antiturning pitch 22 described plastic inner cap 2 periphery, and described metal lid 1 has the enclosing cover antiturning pitch 14 coordinated with described inner cap antiturning pitch 22, described metal lid 1 envelopes described plastic inner cap 2; Described bottleneck 3 has the cambered outwards enclosing cover connected unit 32 of a circle, to curls inward bottom described metal lid 1, enclosing cover inner wrap portion 15 coordinates with the connected unit bottom surface 321 of described enclosing cover connected unit 32.

In practical operation, when turning on twist-broken anti-fake bottle cap, hand acts on metal lid 1, rotational force is applied to metal lid 1, due to metal lid 1 having enclosing cover antiturning pitch 14, it coordinates with the inner cap antiturning pitch 22 on plastic inner cap 2, and the rotational force acted on metal lid 1 passes to plastic inner cap 2 by antiturning pitch, plastic inner cap 2 there is negative thread 21, negative thread 21 coordinates with the outside thread 31 on bottleneck 3, be delivered to rotational force on plastic inner cap 2 and be converted into power upwards by the screw thread coordinated, plastic inner cap 2 is made to produce trend along bottleneck 3 upward movement, due to metal lid 1 coating plastic inner cap 2, and the bottom of enclosing cover bottom 12 is to curls inward, enclosing cover inner wrap portion 15 coordinates with the connected unit bottom surface 321 of enclosing cover connected unit 32, be equivalent to inwardly be buckled in bottom metal lid 1 in the enclosing cover connected unit 32 of bottleneck 3, metal lid 1 and plastic inner cap 2 cannot be moved up as a whole under force immediately, when application force is on hand enough large, make on metal lid 1 when the portion fractures of line of cut 13 place frangibility is opened, can twist-off closure, and bottle cap cannot restore after turning on, and realizes the antiforge function of twist-broken anti-fake bottle cap thus.

Because plastic inner cap 2 adopts plastic material, metal powder can not be produced because of glass bottle opening 3 and the friction of metal lid 1 when turning on inner cap, affecting the use of liquid in bottle.

Specifically, as shown in Figure 2 and Figure 4, described inner cap antiturning pitch 22 is positioned at periphery bottom described plastic inner cap 2, and described enclosing cover antiturning pitch 14 is positioned at bottom, described enclosing cover top 11.As shown in Figure 1, the bottom surface of plastic inner cap 2 coordinates with the end face of bottleneck 3, and inner cap antiturning pitch 22 and enclosing cover antiturning pitch 14 are arranged along the periphery, bottom of plastic inner cap 2 after working good, as shown in Figure 5.Inner cap antiturning pitch 22 and enclosing cover antiturning pitch 14 are strip, can be trapezoidal, also can be semi-cylindrical; Enclosing cover antiturning pitch 14 using metal lid 1 as body, inwardly can extrude formation, also can be attached to the entity on metal lid 1, and equally, inner cap antiturning pitch 22 also can adopt these two kinds of methods shaping.

Specifically, as shown in Figure 2, at enclosing cover line of cut 13 place of metal lid 1, inwardly extruded by metal lid 1, form false proof muscle 16, its effect is fixing metal enclosing cover 1 and plastic inner cap 2 in the axial direction.Enclosing cover antiturning pitch 14 noted earlier and inner cap antiturning pitch 22 can fixing metal enclosing cover 1 and plastic inner caps 2 diametrically, add the effect of the false proof muscle 16 on metal lid 1, make metal lid 1 as a whole with plastic inner cap 2 one-tenth, do identical motion under force.False proof muscle 16 is divided into the upper side and lower side by enclosing cover line of cut 13, matches with the bottom margin of plastic inner cap 2 in upside.

Specifically, as shown in Figure 3, described enclosing cover line of cut 13 place is provided with line of weakness 17, realizes metal lid 1 in enclosing cover line of cut 13 place frangibility with this.The concrete structure of line of weakness 17 carries out hollow out process along enclosing cover line of cut 13 to false proof muscle 16, false proof muscle 16 is formed along enclosing cover line of cut 13 and well-distributed hollow out square, certainly also can be other shapes by the part of hollow out, such as oval etc., as shown in Figure 7.

Specifically, because twist-broken anti-fake bottle cap disclosed in the utility model is used for field of food, and plastic inner cap 2 liquid comes into contact directly and in bottle, therefore the material of described plastic inner cap 2 should select national regulation can be used for food plastics, as PET, HPDE, PP etc.Because metal lid 1 does not directly contact with liquid in bottle, the optional aluminum slice of described metal lid 1 material.
