Abstract

The utility model discloses a twist off type aluminium theft-proof bottle-cap whose theft-proof ring is the structure of single explosion and double crack. N circumferential slots (3), (n-1) connecting bridges (4), a connecting strip (5) are arranged on a cap body. A longitudinal shear mark (6) which is vertically crossed to the circumferential slots is arranged on the theft-proof ring of a circumferential slot which is over against the connecting strip. When the bottle-cap is opened, the theft-proof ring is become two screws with different spiral direction and the connecting band is used as the start point of the screws which are connected to the cap body (1). Thus, the utility model obtains a theft-proof purpose and retains good processability and open usability.

Description

Turn-break type aluminium anti-theft bottle cap

The utility model relates to a kind of package, especially relates to the seal package spare of bottle.

The lid of aluminium anti-theft bottle cap is made by alumina based material, in liner is arranged, be a kind of glass bottle with screw thread mouth or seal package spare of plastic bottle of being applicable to.Be shaped on the pilfer band structure on the lid, bottle cap is after encapsulation, and complete pilfer band just becomes the original packing identity markings of this bottle package on the lid.When bottle cap was opened, pilfer band broke, and bottle cap just can not recover its original packing form, avoids theft, palms off with the method.This bottle cap also has health, advantage such as safe, both artistic and practical, convenient and reliable, is used widely, and has reached tens at China's yearly output.Pilfer band is the keystone configuration feature of this bottle cap, circumferential cut and vertical these two structural elements of cut channel in utilization, accept or reject, different in the combination, formed the bottle cap of different structure feature, as domestic and foreign current split (falling) circle formula (Fig. 2), its structure has only circumferential cut, bottle cap is opened the back pilfer band and is retained on the bottleneck, make troubles for the recycling of bottle, if the repeated usage Bottle and closure, the original packing that disguises oneself as easily, anti-theft is not good enough; Single quick-fried simple check formula (Fig. 3) has several circumferential cut and a vertical cut channel, and after bottle cap was opened, pilfer band became a long spiral and twines bottleneck, to the user make troubles and opening process long; Two quick-fried pair splits formula (Fig. 4), and several circumferential cut and two vertical cut channels are arranged, and when bottle cap was opened, if two vertical cut channels do not pop simultaneously, bottle cap just was difficult to open, and its manufacturing technology difficulty is higher.They all have weak point technically.

The purpose of this utility model provides a kind of new version of aluminium anti-theft bottle cap, is called single quick-fried two formulas of splitting.It combines the advantage of existing product, overcomes its shortcoming, thereby makes novel bottle cap have both good anti-theft, good processability and good unlatching usability simultaneously.

The technical solution of the utility model: the aluminium anti-theft bottle cap is when making pilfer band, on the face of cylinder at Gai Kou edge, along the circumferential direction, by setting size, cut out n circumferential cut (3), form the connecting bridge (4) that has the setting size between (n-1) otch, and the connecting band (5) with setting size, they are connecting lid (1) and pilfer band (2).In the circumference range of the circumferential cut of connecting band, on pilfer band, make a vertical cut channel (6) by the longitudinal size of circle, make with this circumferential cut to intersect vertically, forms one laterally saturating vertical not saturating "T"-shaped.When bottle cap is turned on after encapsulation again, vertical cut channel of pilfer band at first pops, be distributed in (n-1) individual connecting bridge fracture one by one successively of vertical cut channel both sides, bottle cap screws out from bottleneck, present exclusive shape facility of the present utility model: it is the spiral of two different rotation directions of starting point with the connecting band that complete pilfer band has become, be connected on the lid (Fig. 1 b, 1c).Its pilfer band is not retained on the bottleneck, does not have possibility of the original packing that disguises oneself as, and helps the recycling of bottle, and pilfer band does not twine bottleneck, opens convenient, fastly, there is no new technical risk, only needs make an amendment slightly to original cutter, and enforcement is easy.

Preferred plan of the present utility model: the lid thick aluminium sheet punching out of 0.22mm, on the face of cylinder at Gai Kou edge, along the circumferential direction, by (the length of П D-(9 * 0.8+3)) ÷ 9 (D is a bottle cap mouth external diameter), cut out 9 circumferential cut, the size of space that forms between 8 otch is the connecting bridge of 0.8mm.And 1 connecting band (5) that 3mm is wide.At the circumferential location that leaves connecting band center 180 degree, on pilfer band,, make a vertical cut channel by the longitudinal size of circle, its width is 0.10mm, cup depth is 0.15mm, intersects vertically with the circumferential cut at this place.Bottle cap is opened, and present optimum shape of the present utility model: it is two different rotation directions of starting point that pilfer band becomes with the connecting band, and the spiral of equal in length is connected on the lid.

Claims

A kind of turn-break type aluminium anti-theft bottle cap, on the face of cylinder at Gai Kou edge, n circumferential cut along the circumferential direction arranged, form (n-1) individual connecting bridge and a connecting band, connect lid and pilfer band, it is characterized in that: on the pilfer band of the circumferential cut of connecting band, be shaped on a vertical cut channel and this circumferential cut and intersect vertically, form laterally saturating vertically not saturating "T"-shaped, after bottle cap is opened, pilfer band becomes with the connecting band spiral of two different rotation directions that are starting point, is connected on the lid.
