The structure of the metal bottle for filling refined beer includes a can body 100 and a packing member 200.

The can 100 is an integrally formed structure. Moreover, in the present embodiment, the can body 100 is an aluminum product, that is, the can body 100 is an aluminum can, so that the can body 100 has the advantages of light weight, corrosion resistance, durability, environmental protection, recycling, and good economical efficiency and sealing property. Of course, other metallic materials for the can 100 are not precluded. The cross-sectional shape of the can 100 is circular. The can body 100 has a structure including a can body 110, a spherical neck 120, a can bottom 130, and a can mouth 140.

The bottom 130, the body 110, the spherical neck 120 and the mouth 140 are sequentially arranged from bottom to top and connected, so as to form a can body 100 with an upwardly opened mouth, and the can body 100 has an inner cavity with a certain volume and can contain beverage such as fine brewed beer. In this embodiment, the spherical neck portion 120 has a multi-stage necking structure, that is, the spherical neck portion 120 is formed by multi-stage necking, the portion of the spherical neck portion 120 with a large caliber is disposed near the can body 110, and the portion of the spherical neck portion 120 with a small caliber is disposed near the can mouth 140, that is, the caliber of the spherical neck portion 120 tends to increase from top to bottom.

Moreover, the wall thickness of the spherical neck-shrinkage portion 120 is larger than the wall thickness of the can body portion 110, and the wall thickness of the can bottom portion 130 is larger than the wall thickness of the can body portion 110, so that the spherical neck-shrinkage portion 120 can bear larger axial pressure, the requirement of the capping force required in the capping process of the can body 100 is met, the can bottom portion 130 also has stronger bearing capacity, the internal pressure resistance of the can body 100 is promoted to be higher, and the requirement that the refined beer can be fermented again in the can body 100 after being filled in a metal bottle can be met, so that the refined beer can be brewed with rich and complex layers and attractive aroma and flavor with aftertaste.

It can be appreciated that in the process of manufacturing the can body 100, the rolled aluminum is first subjected to a cup punching process on a cup punching machine to form a cup body, the cup body is then subjected to a stretching and thinning process by a stretching machine to form a can body, and the mouth of the can body is subjected to trimming and cutting, cleaning, drying, printing, drying, internal coating, drying, multi-stage necking, video inspection and other processes to manufacture the can body 100. The spherical neck 120 may be formed by a multi-stage necking machine (or necking machine). Because the can body 100 is integrally formed and basically consistent with the traditional pop can forming principle, the existence of three can welding seams can be avoided, the can body 100 is more attractive and sanitary, and the packaging requirement of the refined beer can be met.

In addition, the can body 100 further includes a burring part 150, and the burring part 150 is connected to the can mouth 140. Specifically, one end of the can end 140 away from the spherical neck portion 120 (i.e., the upper end of the can end 140) is bent obliquely downward from the inside of the can end 140 toward the outside of the can end 140 to form a burring 150, and the burring 150 is annular in shape when viewed in the up-down direction. It is understood that the can end 140 may be subjected to a flanging process by a hemming machine so that the flanging portion 150 is manufactured on the can end 140. The upward surface of the burring part 150 is a convex cambered surface, and the downward surface of the burring part 150 is a concave cambered surface.

The package 200 is disposed above the can 100. The structure of package 200 includes a pull ring cover and a sealing gasket 240. The sealing gasket 240 is disposed on one side of the pull ring cover close to the can body 100, and the sealing gasket 240 is fixed to the pull ring cover. The sealing gasket 240 may be made of non-metal materials such as PVC (i.e., polyvinyl chloride), PE (i.e., polyethylene), etc., and is assembled to the tab cover by hot pressing. The pull ring cover covers the opening of the can mouth 140 and is snap-coupled to the lower portion of the burring 150, so that the pull ring cover is fixed with respect to the can body 100, and simultaneously, the sealing gasket 240 contacts with the upper portion of the burring 150, thereby forming a sealing structure between the sealing gasket 240 and the burring 150.

It will be appreciated that the diameter of the pull ring cap may be, but is not limited to, 38mm and the can end 140 and the flange portion 150 are sized to meet the packaging and sealing requirements of the pull ring cap. The pull ring cover has attractive and novel appearance, is convenient to open, and is used for packaging the tank body 100, so that the metal bottle can meet the pressure resistance and sealing requirements of the refined beer, has the characteristics of environmental protection, novelty, fashion, attractive appearance and convenient opening, is attractive to consumers, can be opened without tools, and reduces the opening difficulty. In addition, the metal bottle and the metal can of the embodiment are used in the filling plant, so that the filling is convenient, the equipment is changed little, the investment is little, and the transfer is convenient.

In some embodiments, as shown in fig. 3 and 5, the spherical necked portion 120 has a multi-stage necked structure, the caliber size of the spherical necked portion 120 decreases from bottom to top, and the wall thickness of the spherical necked portion 120 increases from bottom to top.

It will be appreciated that the material of the necked-down portion 120 is correspondingly thickened each time the necked-down portion 120 is necked down by a multi-stage necking process, which causes the wall thickness of the necked-down portion 120 to be substantially thicker than the wall thickness of the can body 110, thereby further improving the axial bearing capacity of the can body 100 and better meeting the required capping force requirements for capping.

In some embodiments, as shown in fig. 3 and 5, a spherical protrusion 131 is formed to protrude upward at a middle position of the can bottom 130, that is, the bottom surface of the can body 100 assumes an inwardly recessed state.

It will be appreciated that the can end 130 is formed by a stretch process, the wall thickness of the can end 130 being the thickness of the rolled aluminum stock material, and the wall thickness of the can end 130 being greater than the wall thickness of the can end 110, whereby the can end 110 is stretch thinned. Because the bottom 130 is provided with the spherical protruding portion 131, the bottom 130 is subjected to a certain downward pressure in the process of secondary fermentation of the refined beer in the can body 100, and at this time, the upward protruding spherical protruding portion 131 can effectively counteract the downward pressure force, so that the bottom 130 is not easy to deform, and the pressure bearing performance of the bottom 130 is further improved. The wall thickness dimensions of the bulbous neck portion 120, the can bottom 130 and the can body 110 may be set according to actual requirements and are not particularly limited herein.

In addition, the can body 110 is thickened as compared to a conventional can, so that the thickness and strength of the can body 110 are increased, and the internal pressure endurance of the can body 100 is enhanced.

In the present embodiment, as shown in fig. 5 to 7, the flanging portion 150 has a structure including a first bending portion 151, a second bending portion 152, an extending portion 153, and a third bending portion 154.

The inner end of the first curved portion 151 (i.e., the inner ring of the first curved portion 151) is integrally formed with the can mouth 140, and the outer end of the first curved portion 151 (i.e., the outer ring of the first curved portion 151) is bent downward by 90 ° to form the second curved portion 152, and the second curved portion 152 has a circular shape as viewed in the up-down direction. The upper end of the second bending portion 152 (i.e., the inner ring of the second bending portion 152) is integrally formed with the first bending portion 151, and the lower end of the second bending portion 152 (i.e., the outer ring of the second bending portion 152) extends downward in a straight line to form an extending portion 153, and the extending portion 153 is annular when viewed in the vertical direction. The upper end of the extension portion 153 is integrally formed with the second bending portion 152, and the lower end of the extension portion 153 is bent inward by 90 ° to form a third bending portion 154, and the third bending portion 154 is annular when seen in the up-down direction.

As shown in fig. 7, in the present embodiment, the outer diameter D1 of the burring 150 is 37.85mm, the inner diameter D2 of the burring 150 is 30.7mm, and the height H of the burring 150 is 4mm. In addition, the closure limiting diameter D3 of the can 100 is less than D1, but greater than D2.

When the pull ring cover is packaged on the can body 100, the sealing gasket 240 abuts against the second bending portion 152, so that a sealing structure is formed between the sealing gasket 240 and the second bending portion 152, external air is prevented from entering the can body 100, and refined beer in the can body 100 is prevented from leaking outwards. The tab cover is then snap-fitted over the third curved portion 154, thereby allowing the tab cover to be securely fastened to the can body 100 and ensuring that the gasket 240 is in constant abutting contact with the second curved portion 152.

Further, as shown in fig. 7, a bending radius (i.e., a curvature radius) R1 of the first bending portion 151 is smaller than a bending radius R2 of the second bending portion 152, and the bending radius R1 of the first bending portion 151 is larger than a bending radius R3 of the third bending portion 154. By such a design, the contact area between the second bending portion 152 and the gasket 240 can be increased.

In the present embodiment, the bending radius R1 of the first bending portion 151 is 1mm, the bending radius R2 of the second bending portion 152 is 2.4mm, and the bending radius R3 of the third bending portion 154 is 0.65mm. Of course, the specific values of the bending radii of the first bending portion 151, the second bending portion 152, and the third bending portion 154 may be selected according to actual needs.
