Abstract

The utility model relates to an anti-fake bottle cap in turn-break rotation-stop type, wherein a breaking piece is provided on the outer wall close to the upper end of the bottle opening, an outer thread is provided on the middle part of the bottle opening, an annular boss is provided on the outer wall close to the lower end of the bottle opening, a rotation stopping piece is provided on the bottom portion of the outer thread close to the annular boss. A threaded inner ring is fixed to the inside of the upper cap, which includes an inner thread matched with the outer thread. The upper cap is further equipped with a claw for holding the breaking piece, and a hung end of the claw is disposed in the range of inner wall circle of the threaded inner ring. The lower sleeve comprises a threaded support piece equipped with inner thread matched with the outer thread on the inner surface thereof, and a returning stopping piece disposed thereon. When the upper cap is returned to the position, because the hung upper end of the returning stopping piece is kept at the lower edge of the annular boss, the bottle opening can not be turned down, an interval between the upper cover and the lower sleeve emerges consequently. The interval indicates that the bottle has been opened, thus has anti-fake display function.

Description

Twist off the tooth-like anti-fake bottle lid of spline

(1), technical field

The utility model relates to a kind of anti-fraud functional bottle cap that has, and specifically, is to twist off the tooth-like anti-fake bottle lid of spline.Mainly be used as the anti-counterfeit package capping of high-grade bottled drinks, beverage and other bottling liquids.

(2), background technology

Existing anti-fake bottle lid generally has the structure of more complicated, such as the patent No. that proposes before the applicant 200520084469.4 " the anti-combination cover that pours in down a chimney of antifalse ", the patent No. is 200420099499.8 " split type plastics anti-fake bottle lid ", and the patent No. is 200420099500.7 " a plastics anti-fake bottle lid " etc.Because complex structure, not only increased manufacturing cost, and use stability can not be satisfactory.

Existing in addition anti-fake bottle lid, owing to still have the recoverable possibility of many parts, its false proof effect is relatively poor.

(3), utility model content

Technical problem to be solved in the utility model is, what a kind of new structure was provided twists off the tooth-like anti-fake bottle lid of spline, it has simple and practical structure and failure-free anti-counterfeiting performance, can satisfy the false proof requirement of bottle well, to overcome the deficiency of above-mentioned existing procucts.

The utility model has adopted following technical scheme.

A kind of tooth-like anti-fake bottle lid of spline that twists off comprises bottle neck, is installed on the loam cake of bottle neck upper end, and the upper end is installed on the bottle neck and be the trapping of plastic material, and it is characterized in that:

Bottle neck is provided with the explosion part near the outer wall of upper end, and bottle neck middle part outer wall is provided with outside thread, and bottle neck is provided with annular boss near the outer wall of lower end, is provided with the spline part in the externally threaded bottom of bottle neck near annular boss;

The loam cake internal fixation has ring in the screw thread, the negative thread of ring matches with aforementioned outside thread in this screw thread, on cover and also be provided with the claw that is used for the described explosion part of clamping, this claw one end one is fixed in the loam cake, the other end is unsettled, and this unsettled end is positioned in the described screw thread ring inwall circumference range;

Following set upper side is provided with the screw thread strut member, and the medial surface of screw thread strut member has the negative thread that matches with aforementioned outside thread, under put and also be provided with non-return position part, put under part lower end, described non-return position one is fixed in, the upper end is unsettled.

Each bottle neck is provided with two to six (preferred four) explosion parts and two to six (preferred four) spline parts; Each loam cake is provided with two to six (preferred four) claws; Each is provided with two to six (preferred four) screw thread strut members in the set upper side down, and each is trapped and is provided with two to six (preferred four) non-return position parts.

Good effect of the present utility model is: after screwing the loam cake certain angle when uncapping, claw contacts with the explosion part, and loam cake drives the bottle neck rotation by the explosion part and rises, behind the rising certain distance, the screw thread strut member engages with the spline part, and the restriction bottle neck continues rotation, and claw is quick-fried with explosion part card.At this moment, under part unsettled upper end in non-return position is moved to by the top of annular boss.When loam cake being installed and press the opposite sense rotation,, make bottle neck to descend owing to the unsettled upper end of part, non-return position is stuck in the lower edge of annular boss, loam cake and trap between have certain interval all the time.This gap shows that bottle cap once was opened, and plays false proof demonstration effect.

(5), the specific embodiment

As shown in Figure 1, 2, this anti-fake bottle lid is installed on the loam cake that is similarly plastic material 2 of bottle neck 4 upper ends mainly by the bottle neck 4 of plastic material, and the upper end is installed on the bottle neck 4 and also 3 be formed by connecting for trapping of plastic material.Can also socket aluminum barrel 1 outside this anti-fake bottle lid.

Wherein, the planform of bottle neck 4 is shown in Fig. 1,2,5,6.Bottle neck 4 is provided with four explosion part 4-1 near the outer wall of upper end.Bottle neck 4 middle part outer walls are provided with outside thread 4-2.Bottle neck 4 is provided with annular boss 4-3 near the outer wall of lower end.Bottom at described outside thread 4-2 is provided with four spline part 4-4, the outside thread 4-2 position that spline part 4-4 and bottle neck 4 are wholely set at bottle neck 4 near annular boss 4-3.

Referring to Fig. 1,2,7,8, loam cake 2 internal fixation have ring 2-1 in the screw thread, and the negative thread of ring 2-1 matches with aforementioned outside thread 4-2 in this screw thread.Also be provided with four claw 2-2 that are used for the described explosion part of clamping 4-1 on the loam cake 2, this claw 2-2 one end one is fixed in the loam cake 2, and the other end is unsettled, and this unsettled end is positioned in the described screw thread ring 2-1 inwall circumference range.

Have that plastics are intrinsic elastomericly traps 3 shown in Fig. 1,2,3,4, its upper end is provided with four screw thread strut member 3-1, and the medial surface of each screw thread strut member 3-1 all has a negative thread that matches with aforementioned outside thread 4-2.Also be provided with four non-return position part 3-2 on 3 trapping, part 3-2 lower end, described non-return position one is fixed in traps on 3, and the upper end is unsettled.

The process of uncapping is: after screwing loam cake 2 certain angles, described claw 2-2 contacts with explosion part 4-1, loam cake 2 drives bottle neck 4 rotations by explosion part 4-1 and rises, behind the rising certain distance, screw thread strut member 3-1 engages with spline part 4-4, restriction bottle neck 4 continues rotation, and claw 2-2 is quick-fried with explosion part 4-1 card.At this moment, under part 3-2 unsettled upper end in non-return position is moved to by the top of described annular boss 4-3.Take off loam cake 2.

When the opposite sense rotation is installed and press to loam cake 2,, make bottle neck 4 to descend, loam cake 2 and trap and have certain interval between 3 all the time owing to the unsettled upper end of part 3-2, non-return position is stuck in the lower edge of annular boss 4-3.This gap shows that bottle cap once was opened, and plays false proof demonstration effect.
