Abstract

The utility model relates to an easy-to-pull bottle cap, which is composed of a cover top and a moire edge. The moire edge extends a pull part outwards, and the pull part is tightly stuck with the moire edge and then is stuck with the cover top after bending. One shear mark takes one adjacent point of the moire edge and pull part as a start point to extend, deviates from the other adjacent point, and then extends along the upper edge of the moire edge. The circular arc extended from the shear mark is not less than 90 DEG. The end of the pull part needs to be pulled, and the shear mark is pulled by force to easily pull the bottle cap. The utility model does not need a bottle opener and can avoid the defect caused by poor riveting.

Description

Easy-open bottle lid

The utility model relates to the small-bore bottle cap of carbonated drink, beer bottle one class, especially a kind of the need with opening the tearing open form bottle cap that bottle instrument is opened.

Crown-shaped (also claiming More limit type) bottle cap that carbonated drink, beer bottle are continued to use for a long time must can be opened by instrument, and the user has inconvenience more.For overcoming this defective, various easy-open bottle lids have appearred, wherein be the structure of using cover of pop can mostly, cooperate with the cut channel on draw ring and the bottle cap, because crown plug uses the tin-plate harder than aluminium to make, draw ring is difficult to be connected with lid, usually can lose efficacy because of draw ring comes off, and perhaps loses efficacy because of cut channel is improper; The someone has designed draw ring is connected one with the More limit easy-open bottle lid for this reason, tops is close to after being close to More's spring folding by draw ring portion, see what Chinese patent 96223180 was put down in writing, but, this bottle cap is not having can't to draw back bottle cap under the condition of cut channel, even having under two parallel cut channel conditions,, draw back bottle cap and also require great effort because of drawing back two cut channels simultaneously.

The purpose of this utility model provides a kind of easy-open bottle lid, and to the cut channel rational deployment of bottle cap, existing draw ring is connected the advantage of one with the More limit, can draw back bottle cap easily again.

The technical solution of the utility model is: a kind of easy-open bottle lid, tops and More limit portion with same sheet material punching out constitute, More limit portion stretches out and forms one and draw back portion, tops is close to after being close to the bending of More limit portion by the portion of drawing back, it is characterized in that: a cut channel is that starting point is extended along More limit portion top periphery after another point of interface direction is extended and departed from another point of interface with More limit portion with a point of interface that draws back portion, and the circular arc that cut channel extends is not less than 90 degree.

Be further described below in conjunction with embodiment of the present utility model and accompanying drawing thereof.

Fig. 1 is the expansion drawing of embodiment of the present utility model.

Fig. 2 is the structure cutaway view of embodiment of the present utility model.

Fig. 3 is the birds-eye view of Fig. 2.

Consult each accompanying drawing, a kind of easy-open bottle lid constitutes with the tops 2 and the More limit portion 5 of same sheet material punching out; More limit portion 5 stretches out and forms one and draw back portion 4, draws back and is close to tops 2 after 5 bendings of More limit portion are close to by portion 4, and all available die stamping of above structure is finished; Stamp out a cut channel 3 simultaneously, cut channel 3 is that starting point is extended along More limit portion 5 top peripheries after another point of interface b direction is extended and departed from another point of interface b with a More limit portion 5 and a point of interface a who draws back portion 4; The circular arc that cut channel 3 extends should be less than 90 degree, otherwise draw back yet easy-open end not of whole cut channels, and the circular arc that cut channel 3 extends preferably is bordering on 180 degree, like this, can draw back bottle cap easily when the application of force is drawn back cut channel.Draw back the termination of portion 4 and adopt draw ring 1 usually, be convenient to the application of force, also can adopt other shape, as sheet.Tops 2 is an inside depressed part 6, draws back the termination of portion 4, lives in seclusion in depressed part 6 as draw ring 1, so, does not increase the height of bottle cap, can directly use on ready-made canning line.

The utility model has the advantages that and be convenient to open, when opening the bottle wine that encapsulates with this bottle cap, Only need break the termination of the section of pulling open into two with one's hands, such as draw ring, the application of force is pulled open cut channel, and bottle cap is opened immediately, Do not need in addition standby Bottle opener; Because cut channel only has one, the starting point of cut channel is in More limit section again A point of interface place with pulling open section slightly is partial to another point of interface application of force, just can be easily Pull open bottle cap; Cancelled again simultaneously draw ring commonly used in the prior art and the riveted joint of lid, Avoided the deficiency being not good at bringing because of riveted joint.

Claims (4)
