Description

A kind of bottle cap

The application is application number is 2014104103026, and the applying date is on 08 19th, 2014, and denomination of invention is the divisional application of " bottle cap and manufacture method thereof, the diel of manufacture bottle cap and bottle "。

Technical field

The invention belongs to container seal technical field, particularly relate to a kind of bottle cap and manufacture method thereof, the diel of manufacture bottle cap and bottle。

Background technology

On existing market, most alcoholic drink, carbonated beverage, canned food etc. all adopt vial to contain, but, owing to vial is difficult to the screw thread fine to inject comparison as plastic bottle, so vial is generally adopted irony or steel material making bottle cap, because irony or the material of steel there is good hardness, and be prone to together with body inclusion after being processed into certain shape。But, owing to the bottle cap of irony or steel has good hardness, and tight with body inclusion, so needing special instrument just can open it。

Generally, after people buy alcoholic drink, carbonated beverage or canned food, such as: medicated beer；But the instrument of medicated beer can not be got out timely。In such cases, carrying out opening beer bottle cap often through tooth, not only can damage tooth, and in the opening process of bottle cap, the excessive beer bottle that rocks causes the pressure within beer bottle to increase, it is possible to cause that beer bottle bursts, thus damaging user。Or adopt the instrument such as table angle of chopsticks or desk to be backed down by beer bottle cap, but, this kind of method needs very big strength, is not suitable for all people。Therefore, it is generally the case that utilize the mode of special bottle opener opening beer bottle cap, it is relatively safety and the widest mode of the scope of application。But, bottle opener is special instrument, and people often carry, and neither can acquire whenever and wherever possible, so that bringing inconvenience very greatly to the personage drunk。

Based on above-mentioned problem, people begin one's study can without the help of bottle opener can the method for open bottle cover very easily, applicant finds through actual survey and by searching document data, and current opening ways mainly has two kinds:

The first is analogous to the mode of pop can open bottle cover, portrays tear line, when needs are drunk on bottle cap, it is possible to caught hold of by the draw ring of tear line one section, is then firmly torn along tear line by bottle cap, by this kind of mode open bottle cover。But, bottle cap is prepared by the material adopting irony, adopts the material of aluminum matter to prepare, therefore, want to tear bottle cap, it is necessary to ratio pulls open the strength that pop can is bigger unlike the draw ring of pop can。But, existing pop can is all difficult to open for some disadvantaged group, is torn by the bottle cap of irony still more。Further, the depth ratio of the tear line on bottle cap is relatively difficult to, if processing shallow, it is easy to cause that bottle cap is difficult to tear apart；If processing deep, such as: beer bottle cap, the pressure within beer bottle rocks increase with beer bottle, it is possible that cause that bottle cap is washed open by the air pressure in bottle。Further, owing to bottle cap is prepared by the material adopting irony, even if after having torn, it may not be possible to completely bottle cap is removed from bottleneck, in order to completely remove the bottle cap with sharp tearing port, it is possible to can cause scratching。

The second is to fix a draw ring at the edge of existing bottle cap by rivet, welding manner, by this draw ring of tractive thus the whole bottle cap of pull-up。But, owing to bottle cap is irony and only draws bottle cap by draw ring, so, the dynamics that pull-up bottle cap needs is very big。Therefore, still there is inconvenient problem with use in this kind of mode, also has, and owing to rivet, the insecure bottle cap that may result in of pad fail to open, finally must use bottle opener。

In order to solve above-mentioned two kind opening ways Problems existing, applicant has invented a kind of beer bottle cap (Chinese utility model patent on October 12nd, 2011, the patent No.: ZL201120386981.X), this beer bottle cap includes iron cap shell and is arranged at the seal gasket of iron cap shell inner top, described iron cap shell includes the cap of a disc-shaped and has the skirt section of fold, described fold is positioned at the upper end in skirt section, the lower end of this fold is additionally provided with multiple perforation, multiple perforation arrange around skirt section surrounding, spoke and an annular iron ring between two perforation connect, described annular iron ring is positioned at the bottom in skirt section。

But, although although the applicant expects that this kind of bottle cap solves the inconvenient problem of opening existing for above two opening ways, but it is more to there is consuming raw material, causes the problem that cost rises to some extent。Because, bottle cap belongs to disposable product, and make consumption very big, if the cost increase red cent of every bottle cap, for manufacturer, it will increase a no small production cost, so how ensure to greatest extent to manufacture on the basis constant with raw-material cost, solve the problem that existing bottle cap is difficult to open, be technical problem urgently to be resolved hurrily。
