Abstract
The utility model relates to a pulling ring of a can easy opening cover, which aims the solve the technical problem that the pulling ring existing in the prior art is usually bent and is difficult to open or can not open the cover. A pulling ring of the easy opening cover with big angle rolling edges of the utility model comprises a finger hole (1), a riveting hole (2), a connecting part (3) and force reducing lines (4). The utility model is characterized in that both outer side edges of the connecting part (3) are provided with rolling edges toward reverse surfaces and the angle alpha of each rolling edge is not smaller than 210 DEG. The utility model has the advantages of simple structure, beautiful appearance, obvious pulling ring strength increase, etc. The utility model is convenient for opening the easy opening cover.
Description
Technical field
The utility model belongs to the technical field of packing container, specifically is the draw ring on a kind of can easy-open end.
Background technology
The can easy-open end utilizes draw ring to open.When uncapping, finger-hole one end with draw ring is pulled away from lid earlier, just oppresses lid at the opposite force that the draw ring other end is produced, the stressed back fracture of the line-marking part on the lid, thus open easy-open end.Existing draw ring adopts the thin slice of aluminium or tin-plate to make usually, and material is softer.Though there is crimping in the outside, both sides at finger-hole and rivet hole connecting portion, the volume angle of crimping becomes the opening shape much smaller than 180 °, only plays the effect that does not scratch finger, can not significantly improve the intensity of connecting portion.Therefore, when opening easy-open end, the stressed bending of draw ring, easy-open end situation about maybe can not uncap not appear in regular meeting.If utilize increase draw ring thickness to improve draw ring intensity, both increased the cost of material, influence can single-piece aesthetics again.
Summary of the invention
The utility model technical issues that need to address are that the bending strength of raising easy-open end draw ring prevents the draw ring bending, thereby opens easy-open end easily.
The easy-open end draw ring of wide-angle crimping of the present utility model comprises finger-hole, rivet hole, connecting portion and subtracts the line of force, and two outer side edges that it is characterized in that described connecting portion have the crimping towards reverse side, crimping angle [alpha] 〉=210 °.As preferably, described crimping contacts with the outer side edges end face, forms the crimping of remaining silent; The most preferred, this crimping is circular crimping.Draw ring is opened easy-open end and is come down to have utilized lever principle, and connecting portion is in the lever position between finger-hole and the rivet hole, its two outer side edges adopts wide-angle, makes that until the crimping of remaining silent the bending strength of draw ring is improved effectively, thereby realizes the purpose of the present utility model.
As preferably, the wide-angle crimping extends to by the side position beyond the rivet hole center of circle and the shaft axis vertical with the draw ring central axis.Thereby further improve the draw ring bending resistance.
As preferably, the described line of force that subtracts is a water chestnut groove shape, and notch is over against the top of draw ring, and this can reduce the anti-ability of tearing of draw ring, is more convenient for opening easy-open end.
The utlity model has advantages such as simple in structure, aesthetic in appearance, that the draw ring bending strength significantly improves, the unlatching of the easy-open end of being more convenient for.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is A-A cutaway views of accompanying drawing 1.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described further.
Embodiment 1: see accompanying drawing 1 and accompanying drawing 2, the easy-open end draw ring of this routine wide-angle crimping, it has connecting portion 3 between a finger-hole 1 and rivet hole 2 and finger-hole 1 and the rivet hole 2, and two outer side edges of connecting portion 3 have adopted towards the circle of the reverse side crimping of remaining silent, and the crimping angle [alpha] reaches about 300 °.The crimping of remaining silent of this routine draw ring extends to by the rivet hole center of circle and shaft axis in addition the side position vertical with the draw ring central axis.Simultaneously, subtract the line of force 4 for being water chestnut groove shape, notch is over against the top of draw ring.Because two outer side edges of draw ring connecting portion adopt the crimping of remaining silent, and the length of the crimping of remaining silent covered the stressed lever position of draw ring, and water chestnut groove shape has reduced the anti-ability of tearing of draw ring again, and to open easy-open end convenient thereby make.
Claims (6)
1, a kind of easy-open end draw ring of wide-angle crimping comprises finger-hole (1), rivet hole (2), connecting portion (3) and subtracts the line of force (4), and two outer side edges that it is characterized in that described connecting portion (3) have the crimping towards reverse side, crimping angle [alpha] 〉=210 °.
2, the easy-open end draw ring of wide-angle crimping according to claim 1 is characterized in that described crimping contacts with the outer side edges end face, forms the crimping of remaining silent.
3, the easy-open end draw ring of wide-angle crimping according to claim 2 is characterized in that the described crimping of remaining silent is circular crimping.
4,, it is characterized in that described wide-angle crimping extends to by rivet hole (2) center of circle and shaft axis in addition the side position (3-1) vertical with the draw ring central axis according to the easy-open end draw ring of claim 1 or 2 or 3 described wide-angle crimpings.
5, according to the easy-open end draw ring of claim 1 or 2 or 3 described wide-angle crimpings, it is characterized in that the described line of force (4) that subtracts is water chestnut groove shape, notch is over against the top of draw ring.
6, the easy-open end draw ring of wide-angle crimping according to claim 4 is characterized in that the described line of force (4) that subtracts is water chestnut groove shape, and notch is over against the top of draw ring.
