Description
Technical field
The utility model relates to easy open cover technical field, especially a kind of high strength easy open cover with dark capel.
Background technology
Pop can entirety is made up of aluminum alloy materials, has and conveniently opens, is easy to carry about with one and callable advantage, be widely used in the industries such as beverage, can, milk powder, such as common canned Coca-Cola.In national standard, the compressive resistance of the easy open cover on pop can be there are certain requirements, if its compressive resistance is inadequate, then lid can be caused to break, cause the fluid leakage of inner splendid attire, even cause quick-fried spray.
Along with the environmental protection weight-saving of pop can industry is carried out, easy open cover on pop can also does thinner and thinner, but along with the reduced thickness of easy open cover, inevitably bringing a problem is exactly: along with easy open cover is thinning, the compressive resistance of easy open cover also correspondingly reduces.And national standard requires that the compressive resistance of easy open cover is at more than 610KPa, so, how to meet on the basis of national standard in guarantee easy open cover compressive resistance, realize easy open cover lightening, become a great technical barrier.
Utility model content
The purpose of this utility model, overcomes the deficiencies in the prior art exactly, and provide a kind of dark capel high strength easy open cover, this device not only can ensure that the compressive resistance of easy open cover meets national standard, and achieves the lightening of easy open cover.
In order to achieve the above object, following technical scheme is adopted:
A kind of dark capel high strength easy open cover, includes lid, and described lid is followed successively by sealed cans region, dark capel and center capping from periphery to center; Described center capping is 2.5 ~ 2.6mm to the distance of the nadir of dark capel; Described lid is made up of the punching press of subcircular material.
Further, the thickness of described center capping is 0.254 ~ 0.245mm.
As a kind of specific embodiment, described sealed cans region is connected and composed successively by crimping, sealed cans plate and sealed cans circular arc.
Further, described dark capel includes the section of immersing oneself in sealed cans circular sliding slopes, the capel extension be connected with center capping and the capel arc section be connected between the section of immersing oneself in and capel extension.
As a kind of specific embodiment, described subcircular material is aluminum alloy.
As a kind of specific embodiment, this easy open cover also includes the draw ring be riveted on lid.
Compared with prior art, the beneficial effects of the utility model are:
The utility model forms a dark capel by carrying out punching press to subcircular material, improves the unit area of thrust surface of easy open cover, thus improves the withstand voltage level of finished product easy open cover in thinning lid material situation; Ensure that withstand voltage level meets on the basis of national requirements, achieve the slimming of easy open cover; The subcircular of the utility model design simultaneously material carries out punching press easy open cover, and actv. eliminates rolled material anisotropy, the problem of lid limes marginis inequality, the effective outward appearance that ensure that easy open cover and crimp quality, the even leak tightness of seaming.Meanwhile, because the slimming of easy open cover, make the weight of each easy open cover can reduce about 0.15g, namely saved the cost of raw material of 5%, therefore, create huge economic benefit.
Accompanying drawing explanation
Fig. 1 is dark capel high strength easy open cover schematic diagram described in the utility model.
Fig. 2 is dark capel high strength easy open cover cross sectional representation described in the utility model.
Fig. 3 is dark capel high strength easy open cover cross-sectional plane partial enlarged drawing described in the utility model.
Fig. 4 is dark capel high strength easy open cover subcircular material schematic diagram described in the utility model.
Detailed description of the invention
Describe the utility model in detail below in conjunction with accompanying drawing and specific implementation method, be used for explaining the utility model in exemplary embodiment and description of the present utility model, but not as to restriction of the present utility model.
As shown in Figure 1, 2, 3, a kind of dark capel high strength easy open cover, the draw ring 2 including lid 1 and be riveted on lid.Described lid 1 is followed successively by sealed cans region 11, dark capel 12 and center capping 13 from periphery to center.Wherein, described sealed cans region 11 includes crimping 111, sealed cans plate 112 and sealed cans circular arc 113; Described dark capel 12 includes the section of immersing oneself in 121 be connected with sealed cans circular arc 113, the capel extension 123 be connected with center capping 13 and the capel arc section 122 be connected between the section of immersing oneself in 121 and capel extension 123.Preferably, easy open cover aluminium alloy material of the present invention is made.
As shown in Figure 3, when being the aluminium of 0.254mm when selecting thickness t, in order to both realize slimming, meet again national compressive resistance standard, the present embodiment by center capping 13 to the distance of the nadir of dark capel 12, namely capel degree of depth h punching press forms a dark capel 12 to 2.5mm, improves the unit area of thrust surface of easy open cover, thus improves the compressive resistance of finished product easy open cover in thinning lid material situation.
When being the aluminium of 0.245mm when selecting thickness t, capel degree of depth h can punching press to 2.6mm; Also, namely, when the aluminium selected is more and more thinner, the value of dark capel degree of depth h needs increasing accordingly.Namely, when aluminium thickness t is 0.254 ~ 0.245mm, the scope of capel degree of depth h is 2.5 ~ 2.6mm.Wherein, because center capping 13 does not deform in punching course, thickness does not change, therefore the thickness of center capping is 0.254 ~ 0.245mm;
Wherein, in order to actv. eliminates rolled material anisotropy, the problem of lid limes marginis inequality, the effective outward appearance that ensure that easy open cover and crimping 111 quality, and the leak tightness of seaming, described lid 1 is made up (being hereafter expressed as subcircular aluminium) of the punching press of subcircular material.
Wherein, the mean diameter of described subcircular aluminium along with center capping 13 is to the distance of the nadir of dark capel 12, namely capel degree of depth h increase and increase, described mean diameter 76.7 ~ 76.76mm.
Further, as shown in Figure 4, the major diameter D of described subcircular material is 76.86 ~ 76.92.mm, and minor diameter d is 76.76 ~ 76.82mm, and minimum diameter md is 76.67 ~ 76.73mm.
The utility model forms a dark capel by carrying out punching press to subcircular material, improves the unit area of thrust surface of easy open cover, thus improves the withstand voltage level of finished product easy open cover in thinning lid material situation; Ensure that withstand voltage level meets on the basis of national requirements, achieve the slimming of easy open cover; The subcircular of the utility model design simultaneously material carries out punching press easy open cover, and actv. eliminates rolled material anisotropy, the problem of lid limes marginis inequality, the effective outward appearance that ensure that easy open cover and crimp quality, the even leak tightness of seaming.Meanwhile, because the slimming of easy open cover, make the weight of each easy open cover can reduce about 0.15g, namely saved the cost of raw material of 5%, therefore, create huge economic benefit.
Above the technical scheme that the utility model embodiment provides is described in detail, apply specific case herein to set forth the principle of the utility model embodiment and embodiment, the explanation of above embodiment is only applicable to the principle helping to understand the utility model embodiment; Meanwhile, for one of ordinary skill in the art, according to the utility model embodiment, detailed description of the invention and field of application all will change, and in sum, this description should not be construed as restriction of the present utility model.
