Description

A kind of draw ring of pop can

Technical field

The utility model is related to a kind of draw ring of pop can.

Background technology

Pop can is often aluminum can body, and the material with cover in itself on top cover is processed to form a rivet, puts outside One draw ring is riveted tightly again, is equipped with that adaptable indentation is convenient to be opened, with lightweight, small volume, non-breakable, portable excellent Point, so enjoying people to favor.But during pop can is opened, because draw ring and cover paste to obtain tension, consumer is normal Often it is difficult to successfully start draw ring, and draw ring and the cover piece that is started together with draw ring are very thin, are easy to make in opening process Into scuffing.

The content of the invention

The purpose of this utility model is to overcome above-mentioned deficiency there is provided a kind of draw ring of pop can, is easy to open, also very Convenient production.

To realize above-mentioned technical purpose, the scheme that the utility model is provided is：A kind of draw ring of pop can, one end of draw ring Riveted with the top cover of pop can, the other end of draw ring is stamping forming folded over portion upwards, and folded over height is no more than pop can Top cover and the convex edge of tank body junction, meet formula h >=a × sin θ, the length of turnover is a, and turnover angle is θ, convex It is h to play shape brim height.

The beneficial effects of the utility model are：It is easy to pull open, it is convenient and practical not hurt hands, do not increase compared with existing draw ring Cost, and eliminate the deep gouge design of easy-to-draw top ends of cans.

Brief description of the drawings

Fig. 1 is the capping top view of pop can.

Fig. 2 is the top cover side view of pop can.

Fig. 3 is Fig. 2 partial enlarged drawing.

Wherein, 1, top cover, 2, draw ring, 2.1, folded over portion, 3, convex edge.

Embodiment

Below in conjunction with the accompanying drawings and embodiment the utility model is described in further detail.

The present embodiment provides a kind of draw ring of pop can, as shown in Fig. 1 ~ Fig. 2, one end of draw ring 2 and the top cover 1 of pop can Riveting, the other end of draw ring 2 is stamping forming folded over portion 2.1 upwards, and folded over height is no more than easy-to-draw top ends of cans 1 and tank body The convex edge 3 of junction, meets formula h >=a × sin θ, as shown in figure 3, the length of turnover is a, turnover angle is θ, convex It is h to play the height of shape edge 3.

In use, because draw ring possesses the upward folded over of certain angle, the finger of consumer very easily clasps draw ring, and And force process is also sufficiently stable, draw ring easily, can be started safely, so as to realize opening pop can.Due to draw ring Upward folded over portion is tab punch shaping, is a part for tab body, need not mold or produce in addition in industrial production Accessory, only need to increase the folded over technique of a step punching press, while also eliminating corresponding in cover after draw ring to be riveted over to cover Place sets up the technique of deep gouge, and technique is simple, cost is low.

Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art For art personnel, on the premise of the utility model principle is not departed from, some improvement or deformation can also be made, these improve or Deformation also should be regarded as protection domain of the present utility model.

Claims

1. a kind of draw ring of pop can, it is characterised in that：One end of draw ring and the top cover of pop can are riveted, and the other end of draw ring is Stamping forming folded over portion upwards, folded over height is met no more than easy-to-draw top ends of cans and the convex edge of tank body junction Formula h >=a × sin θ, the length of turnover is a, and turnover angle is θ, and convex brim height is h.
