Abstract

The utility model relates to an easy opened bottle top which is especially suitable for sealing soda water and beer. A known sealing bottle top with skirt-pleat on periphery is pressed into a circular concave on a cap body surface whose center is downward. A rivet hole is arranged in the concave, and an indentation line for opening winds around the rivet hole. A pull ring is arranged in the concave of the cap body and a rivet is riveted in the rivet hole to fix. Looking from a side face, the shape of the easy opened bottle top is similar to the shape of the known sealing bottle top with skirt-pleat on periphery, so the easy opened bottle top can be directly used for the existing production line and a capping machine does not need to be refitted. When unsealing, other openers do not need.

Description

Easy opened bottle top

The utility model relates to a kind of bottle cap, especially is applicable to the seal cover cap of carbonated drink, beer bottle.

Known a large amount of carbonated drink, beer bottle caps that use on market at present are to realize sealing by its periphery skirt pleat fastening bottleneck convex edge.The seal bottle cap of this periphery skirt pleat must use special tool when opening, very inconvenience.In order to overcome this deficiency, people have designed and multiplely needn't be equipped with in addition the easy-opening bottle cap that opener can be opened, the disclosed a kind of representative easily opened bottle cap of CN2060155U wherein, be on known periphery skirt pleat seal bottle cap, to increase draw ring, rivet and release line etc., draw ring riveting sheet is linked as integral body with draw ring, the draw ring rivet hole is positioned at the draw ring home position, and the release line base portion that punching press forms is walked around and covered the body rivet hole.When opening bottle cap, open draw ring and bottle cap can be opened, do not need special tool along the tearing of release line expansion direction.But this bottle cap is owing to be that auxiliary parts such as draw ring, rivet are fixed on lid, and is higher than the bottle cap surface, can not be directly applied on the packaging machine of known periphery skirt pleat seal bottle cap, during use, also needs improve existing capsuling machine.

The purpose of this utility model is to provide a kind of other instruments that neither need just can open, and can directly be suitable for the easily opened bottle cap that known periphery skirt pleat seal bottle cap capsuling machine uses again.

The scheme that the utility model purpose realizes is: seal in the easily opened bottle cap at known carbonated drink, the beer of lid, skirt pleat, draw ring, rivet, rubber cushion of comprising, when the compacting bottle cap, be pressed into the downward circular depressed in lid face center, corresponding lid bottom surface projection diameter makes this projection can stretch into the internal diameter of bottleneck less than bottleneck.Indentation line that do to open usefulness is arranged on bottle cap, draw ring be contained in the lid sunk part and by closing-up in indentation line, the vertex of draw ring and rivet does not exceed the highest of lid.Two indentation lines ran parallel to bottle cap skirt ruffle after indentation line on the lid face was walked around rivet hole, when opening draw ring, when bottle cap two indentation line expansion direction tearings, sheetmetal upwards opens until final disengaging bottle cap in the indentation line, this moment, breach appearred in bottle cap skirt pleat place, firmly can raise bottle cap a little; Or indentation line walk around be positioned at lid sunk part rivet hole on one side after, two indentation lines rotate with one heart along the lid center of circle and return near rivet hole again, when opening draw ring, when two indentation line expansion direction tearings, along with sheetmetal in the indentation line is torn together with rubber cushion, circumferential notch just appears in lid central authorities, reaches the purpose of uncapping.

The utility model is owing to be fixed on draw ring, rivet in the sunk part of lid, and do not exceed the highest of lid, see similar from the side with the seal bottle cap shape of known periphery skirt pleat, increase height and have annex, therefore can be directly used on a large amount of at present periphery skirt pleat seal bottle cap capsuling machine manufacturing lines that use, that need tool to open with finding out.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is the longitudinal sectional view of an embodiment of the utility model.

Fig. 2 is the birds-eye view of Fig. 1 embodiment.

Fig. 3 is another embodiment indentation line shape scheme drawing of the utility model.

Fig. 4 is the utility model peach shape rivet birds-eye view.

Among first embodiment of Fig. 1-2,1 downward circular depressed in center of bottle cap lid, corresponding lid 1 bottom surface projection diameter is slightly less than bottleneck 2 internal diameters, be encased inside rubber cushion 8 after this projection still can stretch in the bottleneck.Rivet hole 3 is arranged in the sunk part of lid 1 on one side, and indentation line 4 base portions of punching press formation do unlatching usefulness are walked around rivet hole 3 backs two indentation lines as papillary and are run parallel to bottle cap skirt pleat 5 edges.Draw ring 6 is that rivet 7 riveteds of peach heart are in rivet hole 3 by end surface.Whole draw ring 6 is contained in the depression of lid 1, and draw ring 6 and rivet 7 vertexs do not exceed 1 the highest of lid.Adopt 3 in the heart-shaped rivet of peach in conjunction with papillary indentation line 4 base portions, the easier bottle cap of tearing during pulling draw ring 6.

The distinctive points of Fig. 3 embodiment and above-mentioned first embodiment is: after indentation line 4 base portions were walked around rivet hole 3 as papillary, two indentation lines rotated with one heart along lid 1 center of circle and return near rivet hole 3 again.Also there is indentation line at rubber cushion 8 corresponding lid 1 indentation lines 4 places.Draw ring 6, lid 1 and rubber cushion 8 are integral by riveted.During tearing draw ring 6, be together with whole the tearing of rubber cushion 8 sunk parts with lid 1.
