Abstract
The utility model provides a three-piece tank bottom cover and a three-piece tank. The three-piece tank bottom cover is provided with a spherical crown-shaped bottom cover body; a circle of seaming structure is arranged on the edge of the bottom cover body, and the projecting direction of the seaming structure is opposite to that of the bottom cover body. With the adoption of the spherical crown-shaped bottom cover body in the scheme, the deformation resistance of the bottom cover body is improved, and the problem of tank expansion generated after nitrogen is filled in the three-piece tank with the three-piece tank bottom cover is solved.
Description
Technical field
The utility model relates to the packaging container of metal technology, relates in particular to a kind of built-up tin bottom and built-up tin that is used for packaged beverage.
Background technology
Mental package already belongs to the industry of resource-hungry.At present, the pop can of can tea beverage, soda and alcoholic drink adopts built-up tin mostly.
At present, it is the steel plate between the 0.18mm-0.20mm that the tank skin of beverage packing built-up tin generally adopts thickness, and bottom adopts the steel plate between the 0.2mm-0.24mm.Along with soaring of the steel prices of raw and semifnished materials; Adopt the steel plate of above-mentioned thickness to make built-up tin; Increased the tooling cost of enterprise; Therefore, the secondary cold-rolling taggers tin that adopts thickness more to approach (for example thickness is between 0.1mm-0.16mm) is made the important means that built-up tin has become built-up tin manufacturing enterprise to cut down finished cost.Adopt the built-up tin of the secondary cold-rolling taggers tin manufacturing of above-mentioned thickness to come filled drink, must in sealing the forward direction jar, fill liquid nitrogen, liquid nitrogen is gasified in jar and produce malleation, make this built-up tin reach its physical strength requirement.But, as shown in Figure 1, because the bottom main body 1 of existing built-up tin bottom adopts slab construction, behind liquid nitrogen gasification,, make the bottom main body heave to the tank skin outside because jar internal gas pressure raises, produce the problem of " swell ".
The utility model content
The utility model provides a kind of built-up tin bottom and built-up tin, after nitrogen is filled in can, produces the problem of " swell " in order to the built-up tin that solves the manufacturing of available technology adopting secondary cold-rolling taggers tin.
The utility model provides a kind of built-up tin bottom, has domed bottom main body, and the edge of said bottom main body is provided with a circle volume seal structure, and the protrusion direction of the protrusion direction of said volume seal structure and said bottom main body is opposite.
Aforesaid built-up tin bottom, wherein, said bottom main body and said one-body molded connection of volume seal structure.
Aforesaid built-up tin bottom, wherein, said bottom main body and said volume seal structure junction are provided with transition arc.
Aforesaid built-up tin bottom, wherein, the thickness of steel plate that constitutes said bottom main body and said volume seal structure is between 0.1mm-0.16mm.
The utility model also provides a kind of built-up tin; Has tank skin; One end of said tank skin loam cake, the other end bottom that is sealedly and fixedly connected that is sealedly and fixedly connected, said bottom is arbitrary above-mentioned built-up tin bottom, and the protrusion direction of the bottom main body of said built-up tin bottom is in the jar of this built-up tin.
Aforesaid built-up tin bottom, wherein, said built-up tin bottom and said tank skin are sealedly and fixedly connected through the volume envelope with the volume seal structure of said built-up tin bottom.
Built-up tin bottom and built-up tin that the utility model provides adopt domed bottom main body, have improved the ability of bottom main body resistance to deformation, and the built-up tin of having avoided having this built-up tin bottom produces the problem of " swell " after nitrogen is filled in can.
Description of drawings
Fig. 1 partly cuts open structural representation for bottom in the prior art;
Fig. 2 partly cuts open structural representation for the utility model built-up tin bottom embodiment's.
The specific embodiment
Fig. 2 partly cuts open structural representation for the utility model built-up tin bottom embodiment's; As shown in Figure 2, the embodiment of the utility model built-up tin bottom has domed bottom main body 2, and the edge of bottom main body 2 is provided with a circle volume seal structure 4, and the protrusion direction of volume seal structure 4 is opposite with the protrusion direction of bottom main body 2.
Such scheme adopts domed bottom main body 2, has improved the ability of bottom main body 2 resistance to deformations, and the built-up tin of having avoided having this built-up tin bottom produces the problem of " swell " after nitrogen is filled in can.
Particularly, based on the foregoing description, this built-up tin bottom is to be formed by a secondary cold-rolling taggers tin compacting; It has domed bottom main body 2; The one elongation moulding has a circle volume seal structure 4 at the edge of bottom main body 2, that is, bottom main body 2 is formed by a steel plate compacting through integral forming process with volume seal structure 4; Volume seal structure 4 is to the outside of bottom main body 2 turnup, and the protrusion direction of the protrusion direction of volume seal structure 4 and bottom main body is opposite.The volume seal structure is used for that this built-up tin bottom and the tank skin of built-up tin are rolled up envelope and is connected.
Further, based on the foregoing description, bottom main body 2 forms transition arc 3 with volume seal structure 4 junctions, like this, adopts arc transition to improve bottom main body 2 and volume seal structure 4 bonded assembly flatness, has reduced difficulty of processing.
Further, based on the foregoing description, the thickness of steel plate that constitutes said bottom main body and said volume seal structure is between 0.1mm-0.16mm, and for example, the thickness that constitutes bottom main body 2 and the steel plate of volume seal structure 4 is 0.15mm.
The utility model also provides a kind of built-up tin; Have tank skin, an end of tank skin loam cake, the other end bottom that is sealedly and fixedly connected that is sealedly and fixedly connected, wherein; Bottom is the built-up tin bottom of arbitrary the foregoing description, and the protrusion direction of the bottom main body of built-up tin bottom is in the jar of this built-up tin.Adopt domed bottom main body 2 to adopt the bottom main body of slab construction; Under the identical situation of built-up tin internal pressure; The axial force that axial (axially being the short transverse of built-up tin here) power that domed bottom main body 2 receives receives less than the bottom main body of slab construction; Promptly; Receive under the situation of same axial power in the bottom main body of domed bottom main body 2 with slab construction, the pressure that domed bottom main body 2 is born is not difficult to find out greater than the pressure that the bottom main body of slab construction once received; Adopt spherical cap-shaped structure to improve the ability of bottom main body resistance to deformation, the built-up tin of having avoided having this built-up tin bottom produces the problem of " swell " after nitrogen is filled in can.The concrete structure of built-up tin bottom repeats no more referring to the foregoing description here.
Loam cake and bottom all adopt the mode and the tube wall of volume envelope to be sealedly and fixedly connected, and wherein, built-up tin bottom, loam cake all are sealedly and fixedly connected through the volume envelope with the volume seal structure of tank skin with built-up tin bottom, loam cake.Belong to prior art owing to adopt the mode of volume envelope to be sealedly and fixedly connected, repeat no more here.
What should explain at last is: above each embodiment is only in order to the technical scheme of explanation the utility model, but not to its restriction; Although the utility model has been carried out detailed explanation with reference to aforementioned each embodiment; Those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, perhaps to wherein part or all technical characteristic are equal to replacement; And these are revised or replacement, do not make the scope of each embodiment technical scheme of essence disengaging the utility model of relevant art scheme.
