Abstract

The utility model discloses a rotary pry-pull opening type sealing cover, which is realized by that a groove in the shape of thin thread at a wide end of a part to be opened is arranged on the inner side wall of the inner annular groove of the edge of the sealing cover, and a hook-shaped rotary pry-pull opening element is fixed on one side of the wide end of the part to be opened in order to place a hook in the annular groove during rotation. The utility model has the advantages of labor saving, easy opening, wide range of application, easiness for drinking beverages, no environmental pollution and raw material saving.

Description

Revolve sled and draw the open-type seal cover cap

The utility model belongs to the light industrial products technical field, is specially a kind of sled that revolves and draws the open-type seal cover cap.

At present, the pop can seal cover cap that light industry manufacturing, sale and drink manufacturing industry are being used all is to realize with the draw ring above the hard draw during unlatching, as the beverage can of Coca-Cola Co. etc.But the strength that need use when this seal cover cap is opened requires excessive, and along with the carrying out of opening, cracking face width degree increases gradually, and used strength requires also increasing, and strength smaller is difficult for opening.Secondly, draw ring and seal cover cap gap are too little, and finger is difficult for inserting draw ring pull-up difficulty.In fact, also doing the work in Kaifeng when finger inserts, this has just strengthened the difficulty that finger inserts, if and the intensity that weakens draw ring is easily inserted its easy pull-up, finger, be a first step pull-up draw ring, do not implement Kaifeng simultaneously, then can increase the difficulty in next step Kaifeng; If solve problem, be difficult to prevent the natural cracking in the transportation again with increase wait the to ftracture degree of depth of thin-line-shaped groove.Moreover the allowance between opening and the edge is excessive, retains beverage easily, and not only having caused wastes but also contaminated environment.In addition, leftover bits and pieces is bigger when making draw ring, can cause waste of raw materials.Therefore, require great effort, be difficult for drawing back, adaptive surface is narrow, waste and contaminated environment are the unsurmountable defectives of its existence.

Task of the present utility model be to provide a kind of laborsaving, easily open, adapt to wide, beverage is drunk to the greatest extent easily, be difficult for causing environmental pollution and the novel sled that revolves that saves material draws the open-type seal cover cap.

The technical solution of the utility model is: by going up at the circular concavity female lid of sealing (1) triangle is treated that opening section (3) extends to 1/2 place on annular groove (2) madial wall, and leave semicircle platform connected in star wide at the top and narrow at the bottom (4) in its edge, and draw opening tool (5) to realize by the hook-shaped sled that revolves of riveted joint on its wide end one side.During Kaifeng, drawing opening tool hook end to be threaded in the two groove crossings the hook-shaped sled that revolves earlier, continue to rotate in annular groove and prize again, will be the outside for the treatment of opening section that wide end all backs down.Take advantage of a situation then in the direction of the clock and one to revolve and draw, seal cover cap treats that opening section just can all open, thereby finishes the Kaifeng task.Because along with the face width degree of opening that ftractures can reduce gradually, used strength requires also more and more little, so have the labour-saving characteristics; Owing to hook-shapedly revolve sled to draw opening tool be that single armed and fixed end join, intensity a little less than, so have the characteristics of easy pull-up; Draw opening tool and prize and back down or pry open by rotating the hook-shaped sled that revolves, abandoned the hard draw mode, brought into play cutting action and leverage, so have the advantages that easily open with its hook end; The allowance at opening and edge is less, easily beverage is drunk to the greatest extent, saves and characteristics free from environmental pollution so have; Because the hook-shaped sled that revolves draws the used raw MAT'L of opening tool less and leftover bits and pieces is less, so have the advantages that to save material; Because laborsaving, easily open, strength little person also can open, so have the characteristics of wide accommodation.

Now further describe as follows to concrete structure of the present utility model in conjunction with the accompanying drawings:

Fig. 1 is according to the birds-eye view that sled draws the open-type seal cover cap that revolves that the utility model proposes.

Fig. 2 revolves the A-A section-drawing that sled draws the open-type seal cover cap shown in Fig. 1.

Fig. 3 is the birds-eye view that triangle shown in Fig. 1 is treated opening section.

Fig. 4 is the right elevation that triangle shown in Fig. 3 is treated opening section.

Fig. 5 is the front view that triangle shown in Fig. 1 is treated the wide at the top and narrow at the bottom vertical semicircle platform connected in star at the wide end margin of opening section place.

Fig. 6 is that hook-shaped revolving prized the birds-eye view that draws opening tool shown in Fig. 1.

Fig. 7 is that the triangle of riveted joint shown in Fig. 1 is treated opening section and the hook-shaped front view of prizing the rivet that draws opening tool that revolves.

In the accompanying drawings, (1) draws the female lid of open-type sealing for revolving sled, (2) be annular groove in the female lid of the sealing edge, (3) treat opening section for triangle, (4) treat the wide at the top and narrow at the bottom vertical semicircle platform connected in star at the wide end margin of opening section place for triangle, (5) draw opening tool for the hook-shaped sled that revolves, (6) be rivet, button jar reserved part during (7) for the enforcement sealing, (8), (9) are rivet hole, (10) be inside hook corner angle, folded part in the edge that draws opening tool intensity is prized for increasing hook-shaped revolving in (11), (12).

With reference to the accompanying drawings, the utility model comprises: be provided with annular recess (2) in the female lid of circular concavity sealing (1) upper limb, and be provided with the wide triangle by the thin-line-shaped groove regulation of waiting to ftracture in inner narrow outer end and treat opening section (3), and the outer end extends to 1/2 place on annular groove (2) madial wall; Treat that at triangle opening section (3) upward is provided with the hook-shaped sled that revolves and draws opening tool (5) apart from narrow end 2/3 place, by rivet hole (8) and rivet hole (9) and the parallel riveted joint of rivet (6), and the on-fixed end leaves inside hook corner angle (10); Triangle on the female lid of sealing (1) is treated the wide end margin place of opening section (3), is provided with vertical semicircle platform connected in star (4) wide at the top and narrow at the bottom; It is characterized in that the hook-shaped sled that revolves draws opening tool (5) keeping flat to be riveted on triangle and treats on the opening section (3), when rotating it, the inside hook corner angle of its on-fixed end (10) can be put into vertical semicircle platform connected in star (4), and the inside hook corner angle of on-fixed end (10) overall width is slightly larger than the insied width of annular recess (2), and thickness then is slightly less than this insied width.

The hook-shaped sled that revolves described in the utility model draws opening tool (5), it is characterized in that the on-fixed end inside hook corner angle (10) are arranged and not only gained in strength but when guaranteeing pull-up in the not excessive edge of intensity folded partly (11) reach (12).

The sled that revolves described in the utility model draws the open-type female lid of sealing (1), and the reserved part (7) of button jar usefulness when implementing sealing is arranged around it is characterized in that.

In sum, can realize task of the present utility model effectively, for society provide a kind of laborsaving, easily open, adapt to wide, beverage and easily drink to the greatest extent, be difficult for causing environmental pollution, and the novel sled that revolves that saves material draws the open-type seal cover cap.
