Abstract

The utility model relates to a fully releasing type metal easy opening cover, which is mainly used for packaging the openings of utensils containing alcohol and beverage, such as a bottle, a tank and a barrel, and is the improvement of the structure of the existing easy pulling covers. The structure comprises a cover top, a vertical edge and a collapsible pulling ring. The cover top is engraved with knife mark lines (prebroken lines) and a pulling ring base of the pulling ring is fixed on the cover top by a rivet. The knife mark lines (prebroken lines) used for pulling up the pulling ring are engraved on the pulling ring base of the inner side of the rivet. The position of the inner edge of the cover top corresponding to the inner side of the barrel opening, the tank opening and the bottle opening is provided with annular reinforcing ribs. The knife mark lines (prebroken lines) of the cover top are in a star shape. The shape of a prebroken surface is in a streamline shape with a circular arc top. One end of each end point of two end points of each prebroken line of the cover top is communicated with the bottom part of the vertical edge and the other end extends to the middle part of the vertical edge. Compared with the original technology, the utility model has the characteristics of tight package, good sealing performance, opening labor saving, simple operation, etc. Finished product quality is guaranteed.

Description

Take off formula metal easy-open end entirely

Technical field

The utility model relates to a kind of seal closure of packing container, and particularly a kind of formula metal easy-open end that takes off entirely is mainly used in the encapsulation of splendid attire drinks, beverage bottle, jar, bung.

Background technology

Drinks and other beverage, in order to transport and to store, the encapsulation of container utensil oral area is very important, its leak tightness quality is related to the quality of splendid attire product.Disclosed in the prior art packing forms has multiple, and using more is the easy-open lid form, and the seal closure of this structure has played positive role for the quality that guarantees article.But there is following defective in the seal closure of the easy-open lid structure of using at present: be carved with two tool marks lines (being called pre-broken string again) on capping, one is the pre-broken string of draw ring, and another is the pre-broken string of lid, has increased the gas leakage probability of lid; In addition, because the utensil internal pressure is bigger, it is thinner to seal tegmental wall, the lid easy deformation, thus cause poorly sealedly, make utensil produce gas leak phenomenon, the influence product quality of containing; Moreover the pre-broken string at seal closure top is circular, and section is bigger, makes that the resistance when firmly spurring draw ring increases, and causes decylization easily or draw ring is broken, and makes utensil gas leakage, also can influence the stability of product.For this reason, in order to overcome above-mentioned defective, people are striving to find new cap structure always, reclaim problem smoothly to solve because of the utensil improper product design that causes of encapsulation and utensil.

Summary of the invention

The purpose of this utility model be to provide a kind of spur resistance less, be difficult for abscission ring, encapsulation tight take off formula metal easy-open end entirely, can be used for the encapsulation of various drinks, beverage bottle, jar, bung.

In order to realize that the technical scheme that the purpose of this utility model is taked is such.The utility model is that its main improvement is to the improvement of existing metal easy-open lid structure: the pocket knife trace line of using when the first, removing opener tab on the crown cap hd top face (pre-broken string), it is arranged on the draw ring seat, and reduce the gas leakage probability of lid; The second, on hd top face, establish reinforced rib, to avoid because of the raise distortion of the lid cause of utensil internal pressure; Three, dwindle the big formed cross-sectional area of tool marks line (capping breaks in advance) on the hd top face, the pulling resistance when reducing to spur draw ring makes the unlatching lid more smooth and easy.Particularly, structure of the present utility model is such: a kind of formula metal easy-open end that takes off entirely, comprise caping in the structure, stile, draw ring, on caping, be carved with pre-broken string, draw ring is fixed on the caping by the draw ring seat is folding, on the draw ring seat, be carved with pre-broken string, at the caping inward flange, corresponding to bottle, jar, the bung inner side is provided with the annular arrangement reinforced rib, the streamline contour that is shaped as the band dome of the pre-broken string on the caping, the dome of pre-broken string is in the inboard of annular arrangement reinforced rib, end in two end points of pre-broken string passes to the stile bottom, and the other end extends to the middle part of stile.

When actual fabrication, pre-broken string (tool marks line) is engraved in gently with cutter and covers, can not be penetrating, can draw back along this line in the time of firmly, and draw ring is fixed on the caping by rivet or impact style, and the pre-broken string that the pull-up draw ring is used (tool marks line) is engraved on the inboard draw ring seat of rivet.

The formula metal easy-open end that takes off entirely of the present utility model can be used aluminium and other metallic material punch forming.

The utility model is compared the technological advance of obtaining and is with conventional art: crown cap encapsulation closely, good airproof performance, opens laborsavingly, simple to operate, guaranteed Sheng product quality.

Description of drawings

Fig. 1 is a front of the present utility model shaft side figure.

Fig. 2 is a back side of the present utility model shaft side figure.

The implication of each label representative is among the figure:

1, caping 2, stile 3, draw ring 4, rivet 5, draw ring handle 6, draw ring seat 7, caping break at pre-broken string (tool marks line) 9, reinforced rib 10, the lid end that (tool marks line) 8, pull-up draw ring are used in advance.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further.

As shown in Figure 1, a kind of be used to encapsulate the various drinks of splendid attire, beverage bottle, jar, bung take off formula metal easy-open end entirely, integral body aluminium punch forming, comprise caping 1, stile 2, draw ring 3 in the structure, on caping 1, be carved with pre-broken string (tool marks line) 7, draw ring 3 is by draw ring seat 6 usefulness rivets 4 folding being fixed on the caping 1, and the pre-broken string that the pull-up draw ring is used (tool marks line) 8 is engraved on the inboard draw ring seat 6 of rivet 4.At caping 1 inward flange, be provided with annular arrangement reinforced rib 9 corresponding to bottle, jar, bung inner side, the tool marks line on the caping 1 (pre-broken string) 7 is Font, its pre-section are shaped as the streamline contour of band dome, and break an in advance end of two end points of 7 of caping passes to stile 2 bottoms, and the other end extends to the middle part of

stile

2, and 7 the dome of breaking in advance is positioned at the inboard of annular arrangement reinforced rib 9.

Using method of the present utility model is such: with the handle 5 that has pulled draw ring 3, pass through lever principle, the pre-broken string (tool marks line) that the pull-up draw ring is used is that the pre-broken string 8 on the draw ring seat opens brokenly, pull at again, at first the tool marks line on the caping 1 (pre-broken string) 7 dome are opened brokenly, be directed downwards firmly along pre-broken string (tool marks line) 7 then, with the pre-broken string on the caping 1 (tool marks line) 7 smooth and easy drawing back, at last, slightly upwards mention draw ring 3 and the pre-section of the caping that draws back all can be broken away from lid, thereby realize bottle, jar, the smooth unlatching of bung guarantees empty bottle, jar, the complete recovery of bucket.
