Abstract

The utility model discloses a cover of an easily opened can, particularly a cover of an easily opened can for beverage package. The utility model has the technical proposal that the cover of an easily opened can comprises a pulling ring (2), a pulling cover (3), a cover (4), and rivets (5). The cover (4) is provided with the pulling cover (3) that forms an entire body with the cover, the pulling cover (3) is provided with the pulling ring (2), and the pulling ring is connected with the pulling cover by the rivets (5). The cover of an easily opened can is characterized in that the rivets (5) are arranged on the edge of the cover (4), and the end of the pulling cover is connected with the cover. The pulling cover of the utility model can not be separated from the cover after opened, and can not be pressed into the can. The cost can not be raised because the manufacturing technology of the utility model is generally identical with the manufacturing technology of the current two covers. The cover of an easily opened can not only reclaim empty cans but also avoid the drinking safety problem caused by pulling covers pressed into cans.

Description

Drawn-can lid

Affiliated technical field:

The utility model relates to a kind of cover design, the particularly cover of beverage packing pop can of pop can.

Background technology:

At present, the easy open can of beverage packing pop can is stamped two kinds of versions, and a kind of is full tearing type, and a kind of is hold mode.The cover of common pop can generally is made up of draw ring, La Gai, cover, rivet, and cover is provided with the lid that draws that becomes one with it, draws the face of covering to be provided with draw ring, and draw ring is connected by rivet with drawing between the lid, and rivet is in the center of cover.Though it is all with low cost that full tearing type closes two kinds of designs of hold mode, technical maturity each has its fatal shortcoming.Abandoned conveniently easily after the draw ring of full tearing type cover pulls off, can cause environmental pollution and hurt sb.'s feelings easily; The hold mode cover draws lid can be pressed in the jar when the draw ring pull-up, and hygienic like this can not get ensures.

The utility model content:

The utility model purpose provides a kind of drawn-can lid, solves the cover environmental pollution that exists in the background technology, hurts sb.'s feelings and the problem of health concerns easily.

The technical solution of the utility model is: drawn-can lid is formed and is comprised draw ring, La Gai, cover, rivet, cover is provided with the lid that draws that becomes one with it, draws the face of covering to be provided with draw ring, and draw ring is connected by rivet with drawing between the lid, draw the end of lid to link to each other with cover, rivet is on the limit of cover.

The beneficial effects of the utility model are: can not separate with cover after drawing lid to be opened, draw Gai Buhui to be pressed in the jar.And its manufacturing process is identical substantially with the manufacturing process of existing two kinds of covers, can not cause the lifting of cost.

Description of drawings:

Fig. 1 is the structure diagram of the utility model drawn-can lid.

Fig. 2 is the structure diagram before the utility model drawn-can lid installs draw ring additional

Fig. 3 is the structure diagram of the utility model drawn-can lid draw ring

Fig. 4 is the force analysis figure of the utility model drawn-can lid

Among the figure: groove 1, draw ring 2 draws and covers 3, and cover 4, rivet 5, rivet 5 are to draw to cover a part of 4.

The specific embodiment:

Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.

The pulling force that F1 is subjected to for the draw ring end in Fig. 4, F2 are the application force that draw ring that rivet is subjected to makes progress to it, the application force that the cover that F3 is subjected to for the draw ring end makes progress to it, and T1, T2 are the shearing force of drawing the caping end to be subjected to.

The maximum of this utility model and existing structure is not both on the limit that rivet is in cover, rather than the center, and is as Fig. 1, shown in Figure 2.Its use is a tensile force f 1 of making progress for draw ring one at the end of draw ring as shown in Figure 4, at this moment, draw ring can be that the center is rotated with the rivet, and the end of draw ring can be given the downward pressure of cover, by Newton's third law as can be known, the end of draw ring can be subjected to the application force that cover makes progress.Because the rotation rivet of draw ring can be subjected to the directed force F 2 that draw ring makes progress, because draw ring drives and draws that lid is feasible to draw the top of lid to be subjected to shearing force T1 with drawing the lid rivet that links to each other therefore, the effect of T2 draws lid to be torn, draw the end of lid to link to each other, thereby can not torn fully with cover.

Claims

1, a kind of drawn-can lid, have draw ring (2), draw lid (3), cover (4), rivet (5), on the cover (4) be provided with become one with it draw lid (3), draw and be provided with draw ring (2) above the lid (3), draw ring is connected by rivet (5) with drawing between the lid, it is characterized in that rivet (5) is on the limit of cover (4), draws the end of lid to link to each other with cover.
