Description

Anti-fake bottle cap

Technical Field

The utility model relates to a wine bottle cap, in particular to a wine bottle cap with an anti-counterfeiting function.

Background

At present, the common anti-counterfeiting wine bottle caps in the market are various, wherein the common one is that the bottle cap comprises an upper cap, a lower cap and a burst ring, a plurality of notches of connecting points to be disconnected are distributed on the circumference of the burst ring, and a plurality of teeth caps are arranged on the upper end surface and the lower end surface of the burst ring. When the bottle cap is in a screwed state, the upper gear cap is buckled in the square groove of the gear ring at the end of the upper cover port, and the lower gear cap is buckled in the fluted disc positioned between the burst ring and the lower cover, so that the burst ring can be broken along a to-be-broken connecting point when the upper cover is rotated and cannot be restored.

For example, chinese utility model patent document No. CN201071154 discloses an explosion-proof wine bottle cap. As shown in figure 1, the explosion-type anti-counterfeiting wine bottle cap mainly comprises an upper cap 1 ', an inner cap 2' with internal threads 12 ', a connecting cap 3' with external threads 17 ', an inner plug 5', a valve 4 ', a lower sleeve 6' and the like; the upper cover 1 ' is provided with a buckling ring 7 ' and a rotation stopping groove 9 '; the valve 4 'is provided with a column port 22', a waterproof ring 23 'and a sealing rib 24'; the inner plug 5 ' is provided with a pin buckle 27 ' and a sealing opening 28 '; the inner cover 2 'is provided with a buckling rib 10', a rotation stopping rib 13 ', a bursting ring 15' with a bursting opening, a sealing ring 11 'and a small column 14'; the connecting cover 3 ' is provided with a rotation stopping tooth 19 ', a window 21 ', a sealing port 18 ' and a pin 20 '; the lower sleeve 6 'is provided with a thrust ring 30'. The inner cover 2 'is connected with the burst ring 15' through a plurality of points, and the burst ring 15 'is cut through except the connection part with the inner cover 2'. When the anti-explosion cover is used, the upper cover 1 ' is rotated anticlockwise, the explosion ring 15 ' in the inner cover 2 ' is exploded under the force of the rotation stopping teeth 19 ', and the explosion ring 15 ' is divided into a plurality of pieces to automatically fall off when the explosion ring is exploded.

The above-mentioned bottle cap has the following disadvantages:

first, the process is complicated. The integral inner cap is manufactured (the burst ring is a part of the inner cap) and then the inner cap is cut, so that the burst ring and the inner cap are connected only at a plurality of points.

Second, the thickness (or height) of the fracture ring in the axial direction cannot be too thick (high) or else cannot be snapped. In response to this disadvantage, it is known to cut the fracture ring in a plurality of circumferential cuts, in which only a very thin material is connected. However, the fracture ring in this manner lacks a sense of unity and is not aesthetically pleasing, with a large gap visible from the exterior.

Further, chinese utility model patent document No. CN1524053 discloses an anti-counterfeit identification device. The tamper-evident device comprises a sleeve member comprising a first portion connected to a second portion by a frangible portion therebetween, wherein the first portion is adapted for application to the mouth and neck of a container and the second portion is connected to a container closure member, wherein an initial container opening operation causes the frangible portion to break or fracture such that the first and second portions are at a spaced apart position from one another when the container is reclosed. The brittle portion in this embodiment corresponds to a fracture ring, which is cut into a plurality of portions in the circumferential direction, each portion being connected to the upper lid (second portion) and the fracture line being visible from the outside of the fracture ring, which is not aesthetically pleasing. In addition, the fracture ring is also pulled apart by pulling force, and if the fracture ring is not divided into a plurality of parts, the fracture ring cannot be pulled apart at all. Even if a single fracture groove is cut on the inner side of the fracture ring (so that the outer surface of the fracture ring has no parting line), the fracture groove cannot be broken due to the large thickness (or height) in the axial direction.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a novel anti-fake bottle cap is provided, this anti-fake bottle cap's fracture ring adopts the mode of rupture, and fracture ring formula structure as an organic whole before the rupture, and the vestige is not cut apart to the surface of fracture ring.

The utility model discloses the technical problem that solve is realized through following technical scheme: the anti-counterfeiting bottle cap comprises an upper cap, a lower cap and a burst ring positioned between the upper cap and the lower cap; the lower cover is fixedly sleeved at the opening or the neck of the bottle body, the upper part of the lower cover is a protruded columnar part, and the surface of the columnar part is provided with external threads; the inner side of the upper cover is provided with internal threads, and the upper cover is screwed on the columnar part;

wherein,

at least one section of protrusion is annularly distributed on the lower cover, the protrusion is positioned below the external thread, and the protrusion is gradually thickened along the circumferential direction of the columnar part;

the burst ring is sleeved outside the protrusion, at least one protrusion head extends out of the inner surface of the burst ring, and the protrusion head is located at the thinnest position of the protrusion;

the upper part of the burst ring is circumferentially fixed with the upper cover.

According to the anti-counterfeiting bottle cap, the upper cap is rotated to drive the bursting ring to rotate relative to the lower cap, the protruding head on the inner surface of the bursting ring slides along the protrusion on the cylindrical part of the lower cap, and the protruding head of the bursting ring is pushed outwards along the radial direction of the cylindrical part as the thickness of the protrusion is increased more and more until the bursting ring is broken. Compared with the existing breaking mode, the breaking mode is more labor-saving, and the burst ring is more easily broken. Therefore, the burst ring does not need to be cut into a plurality of pieces in advance, or even if the burst ring is larger in axial height of the bottle cap, only the inner side of the burst ring is required to be provided with the fracture groove, and the outer surface of the burst ring does not need to be provided with fracture line marks, so that the integral attractiveness of the bottle cap is ensured.
