Abstract

A bottle neck and a sealed cover thereof, in particular to an anti-counterfeiting bottle neck for containing beverage and wine and a cover thereof, which solve the defects that the metal anti-counterfeiting bottle cap in the prior art has too simple structure, poor scientificity, easy imitation and incomplete anti-counterfeiting without comprehensive improvement on the bottle neck part. The feature is that the bottle neck is divided into three parts of anti-fake, screw thread and boss, the inner sealing ring is inserted into the bottle mouth, on which is an inner cap with an easy-to-pull ring, the lower part of the inner cap is tightly engaged with the upper part of the bottle neck through the closing-up. The outer cap is placed on the inner cap and threadedly engaged with the threaded portion of the neck. Can be used on the improved bottle neck according to the utility model.

Description

Anti-forged bottle-neck and cover

The utility model relates to a kind of bottleneck and leak free lid thereof, the false proof bottleneck and the lid thereof of particularly a kind of splendid attire beverage and wine.

People are for false proof to the bottle of splendid attire beverage and wine in the prior art, and then control is pseudo-, bad beverage and wine flood market, and is to write an article on bottle cap mostly, as the appearance of turn-break type, easy-to-pull metal anti-fake bottle lid.These through improved bottle cap to prevent and treat puppet, bad commodity had once played certain positive role.But because its structure is too simple, and does not comprehensively improve bottleneck portion, it is scientific poor, imitated to cause it still to have, false proof halfway deficiency.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art, has not only all carried out comprehensive improved false proof bottleneck and lid thereof to bottle cap but also to bottleneck and provide a kind of.

Technical solution of the present utility model is: bottleneck (4) is divided into three parts successively, and promptly top is the false proof part (1) of trough of belt and cone angle, and the centre is threaded portion (2), and following again is boss (3).Inner seal ring (5) inserts in the bottleneck, is the inner cap (7) that has pull-tab (6) on it.The false proof part (1) on the bottom of inner cap (7) and bottleneck (4) top is by the tight interlock of closing up.Root is shaped on pre-failure line (10) in the groove of false proof part (1).The inner face of enclosing cover (8) is equipped with exterior seal ring (9), and enclosing cover places on the inner cap (7) and is spirally connected with the screw thread of bottleneck centre portion.

The utility model has following advantage compared to existing technology:

1, scientific strong, of a tightly knit structure.

2, because be shaped on pre-failure line, the false proof part of bottleneck can be fractureed during repeated usage, so false proof thorough.

3, because inner seal ring arranged, sealing is reliable, is furnished with enclosing cover and can be to drink for several times and provide convenience.

4, distinguish true from false intuitively.

5, small investment.

The drawing of accompanying drawing is described as follows: Fig. 1 is the integral structure section-drawing of the utility model bottleneck portion, 1,2,3 and 10 false proof parts that are respectively on the bottleneck 4 wherein, threaded portion, projection section and pre-failure line.

Fig. 2 is the integral structure section-drawing of inner seal ring 5.

Fig. 3 is the integral structure section-drawing of inner cap 7, and wherein 6 is pull-tab.

Fig. 4 is the birds-eye view of Fig. 3.

Integral structure section-drawing when Fig. 5 is used on the bottle on the spot for the utility model, wherein 8 is enclosing cover, 9 is exterior seal ring.

The utility model is described in further detail below in conjunction with drawings and Examples:

Bottleneck (4) is divided into three parts successively, and promptly top is the false proof part (1) of trough of belt and cone angle, and the centre is threaded portion (2), and the bottom is boss (3).Inner seal ring (5) inserts in the bottleneck, is the inner cap (7) that has pull-tab (6) on it.The false proof part (1) on the bottom of inner cap (7) and bottleneck (4) top is by the tight interlock of closing up.Root is shaped on pre-failure line (10) in the groove of false proof part (1).The inner face of enclosing cover (8) is equipped with exterior seal ring (9), and enclosing cover places on the inner cap (7) and is spirally connected with the screw thread of bottleneck centre portion.Can be used for according on the improved bottleneck of the utility model.

Claims

1, a kind of bottleneck and leak free lid thereof, the false proof bottleneck and the lid thereof of particularly a kind of splendid attire beverage and wine, inner seal ring (5) inserts in the bottleneck, the inner face of enclosing cover (8) is equipped with exterior seal ring (9), it is characterized in that, bottleneck (4) is divided into three parts successively, be that top is the false proof part (1) of trough of belt and cone angle, root is shaped on pre-failure line (10) in its groove, the centre is threaded portion (2), the bottom is boss (3), it on the inner seal ring (5) inner cap (7) that has pull-tab (6), the false proof part (1) on the bottom of inner cap (7) and bottleneck (4) top is by closing up tight interlock, and enclosing cover places on the inner cap (7) and is spirally connected with the screw thread of bottleneck centre portion.
