[specific embodiment]
To the embodiment 1 of lever type zip-top bottle cap of the present invention shown in Figure 6, lever type zip-top bottle cap comprises Crown shape bottle cap and draw ring at Fig. 1, and Crown shape bottle cap is that 0.25 millimeter tin-plate sheet material is stamped to form by thickness.Draw ring comprises ring 1 and lever sheet 2, the end face of Crown shape bottle cap and 2 riveted joints of lever sheet.Stealthy cut channel 3 is arranged on the Crown shape bottle cap, stealthy cut channel 3 comprises arc 301 and 2 linear portions 302, the end of 2 linear portions 302 of stealthy cut channel extends to the edge of Crown shape bottle cap, and the arc 301 of stealthy cut channel 3 is walked around the riveting point of Crown shape bottle cap and lever sheet 2.
The center of Crown shape bottle cap is departed from the riveting point of present embodiment, and away from the end (the bottle cap center is between riveting point and stealthy cut channel end) of stealthy cut channel 3, the distance L between the center of riveting point and Crown shape bottle cap is 3.5 millimeters.
The part 5 that Crown shape bottle cap is surrounded by stealthy cut channel 3 and stealthy cut channel 3 peripheries 6 mutually stagger along the normal direction of bottle cap sheet material and form the cut channel that is easy to pull open, and the part 5 of being surrounded by stealthy cut channel 3 outwards protrudes from the periphery 6 that surrounds stealthy cut channel 3.It is 1/5th of sheet metal thickness with the thickness h of surrounding stealthy cut channel 3 peripheries 6 connecting portions that stealthy cut channel 3 surrounds part 5, namely 0.05 millimeter.The structure of the stealthy cut channel of present embodiment not only can reduce the unlatching resistance of bottle cap, also has explosion-proof, when the beer in the bottle in the transportation or during heat or beverage during because of hypertonia, can break through stealthy cut channel, liquid is gushed out from the opening part of the stealthy cut channel of bottle cap in the bottle, prevent that bottle blast from hurting sb.'s feelings, improve the percent recovery of safety and glass bottle.
The angle of 2 linear portions 302 of stealthy cut channel 3 is 37 °.Crown shape bottle cap has 21 lobes 7 and 21 teeth groove 8, and the two ends of stealthy cut channel 3 extend to respectively in 1 teeth groove 8, and the span of two ends of stealthy cut channel 3 just in time is 4 teeth groove.
As shown in Figure 1, the left end of stealthy cut channel 3 extends to the edge of bottle cap always, and 1 section circular arc 303,303 of the right-hand member of stealthy cut channel 3 extends on the lobe in the outside adjacent with this cut channel place teeth groove, and the end of circular arc 303 and the edge of Crown shape bottle cap leave spacing.The two ends of stealthy cut channel 3 extend to respectively teeth groove 8 in, can reduce by the resistance that pulls open of the part 5 of stealthy cut channel 3 encirclements, be convenient to the left end of stealthy cut channel 3 is fully withdrawn, and the edge of the end of 1 section circular arc 303 of right-hand member of stealthy cut channel 3 and Crown shape bottle cap leaves spacing and can prevent from being broken away from fully with periphery 6 by the part 5 that stealthy cut channel 3 surrounds, and can pull down from bottleneck simultaneously.This structure both had been convenient to bottle cap integral body is pulled from bottleneck, also was convenient to the recycling of useless bottle cap.
The lug boss 4 that the riveted joint position of Crown shape bottle cap end face has 1 punching press to form, there is 1 groove at the riveted joint position of lever sheet 2, and 1 riveted holes is arranged in the groove 202, and the lug boss 4 of Crown shape bottle cap end face passes riveted holes and 2 riveted joints of lever sheet of lever sheet 2.
The both sides of lever sheet 2 riveted joint position grooves 202 respectively comprise the crimping 203 to upper process, to increase the rigidity of lever sheet 2.The outside of crimping 203 comprises that the lower end of 204,2 side-struts 204 of upright side-strut withstands on the periphery 6 that the Crown shape bottle cap end face surrounds stealthy cut channel, is stuck in the outside of outwards outstanding stealthy cut channel 3, can prevent that draw ring from rotating around the riveting point.
Lever sheet 2 is comprising 2 relative arc notch 201 with the both sides of the connecting portion of ring, ring 1 has longitudinally reinforced rib 101 at the connecting portion with the lever sheet, in the present embodiment, strong muscle 101 is literal " Qf " that punching press forms, and reinforced rib 101 extends to the connecting portion of lever sheet 2 and ring always.
There is 1 tab 205 rear end of lever sheet 2, and the end face of Crown shape bottle cap has 1 recessed groove 9, and tab 205 is bent downwardly, and inserts in the groove 9 of Crown shape bottle cap end face, can prevent further that draw ring from rotating around the riveting point.
Because the both sides of lever sheet 2 have crimping 203 to play booster action, ring 1 has longitudinally at the connecting portion with the lever sheet, and reinforced rib 101 plays booster action, and the both sides of the connecting portion of lever sheet and ring have 2 relative arc notch 201 to play weakening effect between crimping 203 and reinforced rib 101, such as Fig. 1 and shown in Figure 7, when to open bottle cap, when starting ring 1, lever sheet 2 is inevitable to be bent in the B-B position.That is to say that when starting ring 1, ring 1 rotates take its front end as balance pivot, the B-B position of lever sheet 2 front portions and then is upturned when bending, and rotates take tab 205 as fulcrum.During the B-B position perk of lever sheet 2, utilize leverage to rip stealthy cut channel 3 front end arcs 301, because rip stealthy cut channel 3 front end arcs 301 by lever principle, much more laborsaving than directly pulling open stealthy cut channel.Such as Fig. 8 and shown in Figure 9, had after the anterior breach, spur again ring 1 and just can like a cork the part 5 of stealthy cut channel 3 encirclements be shut down, like a cork bottle cap is integrally pulled from bottleneck.
Embodiments of the invention utilize riveting point, side-strut 204 and tab 205 to prevent that draw ring from rotating, effectively reliable, so present embodiment is well suited for using at canning line, any parts that need not change on the bottle placer can be produced, and can not break down because draw ring rotates.
Another advantage of present embodiment is that the center of Crown shape bottle cap is departed from the riveting point, has reserved larger space for the end face of bottle cap, is convenient to the core print product trade mark at the end face of bottle cap.
