Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, new to this practicality
Technical scheme in type embodiment is clearly and completely described, it is clear that described embodiment is this utility model part
Embodiment rather than whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not doing
Go out the every other embodiment obtained under creative work premise, broadly fall into the scope of this utility model protection.
Fig. 1 is the structural representation of the seamless tank of this utility model, and Fig. 2 is the profile along A-A ' line of the seamless tank in Fig. 1.
Refer to Fig. 1 and Fig. 2, this utility model provides a kind of seamless tank 1, and including precoated metal tank body and cover, tank body includes one
The can body 2 of molding and tank bottoms 3, the consistency of thickness of described can body 2, and on described can body 2, it is provided with rolling muscle 4, described tank bottoms 3
Being arranged on the lower end of described can body 2, described cover lid is located at the upper end of described can body 2 and makes described seamless tank 1 seal.
Seamless tank 1 in this utility model is made up of tank body and cover two parts altogether, and wherein, tank body includes integrated
Can body 2 and tank bottoms 3, does not therefore have connecting sewing to dock on the whole tank body of the seamless tank 1 in this utility model, the most whole
Tank body uniform force a little, tank interior is cavity, it is possible to puts liquid or solid and has good crushing resistance,
Tank body will not be impacted because of the content in tank body or external force and the risk of tank occurs brokenly.Further, the thickness of can body 2
Uniformity, can body 2 is additionally provided with rolling muscle 4, further enhancing the crushing resistance of seamless tank 1, it is ensured that the packaging of seamless tank 1
Safety.
Meanwhile, tank body uses precoated metal to make, and precoated metal is by fusion method or Method for bonding, is overlying on by resin film
On metal basal board.Compared with paint metal, precoated metal has good decoration, heat insulation, stamping resistance, corrosion resistance etc., surface
Consistency is high, more meets food safety and sanitation requirement for packaged food beverage etc..In order to control cost and be easy to seamless tank 1
Transport and conveyance, in this utility model, the precoated metal of seamless tank 1 can specifically use film-covered iron or peritoneum aluminum system
Make.
Further, the thickness of can body 2 is 0.14-0.18mm.
Further, rolling muscle 4 is the ring-shaped depression being arranged on can body 2 circumferencial direction, and the cross sectional shape of ring-shaped depression is
The arc of radius 1.2-1.8mm.Rolling muscle 4 in this utility model can be annular rolling muscle, and this annular rolling muscle is with can body 2
Axis is axle the closed-loop being perpendicular to this axis.In order to strengthen the rolling muscle 4 resistance to compression effect for can body 2, can be by this rolling
Muscle 4 is set to along the can body ring-shaped depression of a week, and the power being applied on can body 2 can be decomposed, be reduced tank by this depression
The size of power on body 2, improves the intensity of seamless tank 1, it is preferred that the cambered surface radius of ring-shaped depression is 1.2-1.8mm.This practicality
The novel number being not intended to roll muscle 4, concrete rolling muscle 4 can be configured according to the needs of client, it is preferable that when rolling muscle 4
When being set to 15, both can guarantee that can body 2 comprcssive strength was obviously enhanced, the processing cost of seamless tank 1 can be made again to be rationalized
Control.
Further, the height of tank body and diameter ratio are 1.0-3.0.In order to effectively balance content pair in seamless tank
The power that seamless tank applies, can be set to 1.0-3.0 by the height of tank body and diameter ratio.On the market in order to meet the most commensurability
The packaging of content, it will usually tank body is divided into low capacity tank and Large Copacity tank according to volume size, therefore at this utility model
In, the height that can control low capacity tank is 1.0-2.0 with diameter ratio, and the height of Large Copacity tank and diameter ratio are 2.0-
3.0。
Further, being provided with flange 5 in the upper end of described can body 2, flange 5 is connected with can body 2 circular arc 6, the width of flange 5
R1 is 2.2-3.0mm.Flange 5 herein is directed towards outside tank body not towards the cavity direction within can body 2.This flange 5
With circular sliding slopes at the upper opening of tank body.Specifically, cover be through with flange 5 card merges finally make cover outer rim and
Circular arc 6 carries out contacting and completes to connect.Preferably, this connection flange 5 is 1.0-2.0mm with the radius of the circular arc 6 of can body 2.
Further, can body 2 and tank bottoms 3 circular sliding slopes, and the radius connecting can body 2 and the circular arc 7 of tank bottoms 3 is 1.5-
2.0mm.This circular arc 7 can make axial force by can body 2 to tank bottoms 3 smooth transmission, and then during producing or using, reduces tank
The deformation extent that the end 3 concentrates due to stress and causes, wherein, the arc radius that this circular arc 7 uses can be such as 1.5-2.0mm.
Further, tank bottoms 3 include bottom surface 9 and are successively set on depressed part 10 and the lobe 8 of bottom surface 9 outer rim, state convex
Play portion 8 to be connected with described can body 2.Specifically, can body 2 with tank bottoms 3 connection be the outer rim of arc surface 7 and lobe 8 and be connected
, say, that the bottom of seamless tank of the present utility model is not a plane, when placing it, only passes through nothing
The lobe 8 of seam pot bottom is with external contact thus completes the steady placement of seamless tank.In order to strengthen the structure of seamless pot bottom
Intensity, prevents it from deforming further, and lobe 8 and bottom surface 9 connect especially by with the depressed part 10 towards tank interior, and
This depressed part 10 and bottom surface 9 circular sliding slopes, and the radius connecting depressed part 10 and the circular arc 11 of bottom surface 9 is 0.8-1.5mm.
Further, the central point of bottom surface 9 is 2.5-3.5mm with the difference in height on the summit of lobe 8;Depressed part 10
End point is 3.0-4.5mm with the difference in height on the summit of lobe 8.Herein, the summit of lobe 8 specifically refers to when being erected by seamless tank
When directly placing, any point in lobe 8 contacted with horizontal plane.
The seamless tank that this utility model provides can realize by the following method:
Employing film-covered iron thin plate is as raw material, through blanking, cup stamping, twice stretching of stretching-machine after elder generation, then by molding
Tank body upper opening deburring, carries out can body rolling muscle processing.Finally easy-open lid is connected with can body, forms seamless tank.
Last it is noted that various embodiments above is only in order to illustrate the technical solution of the utility model, rather than it is limited
System;Although being described in detail this utility model with reference to foregoing embodiments, those of ordinary skill in the art should
Understand: the technical scheme described in foregoing embodiments still can be modified by it, or to the most some or all of
Technical characteristic carries out equivalent;And these amendments or replacement, do not make the essence of appropriate technical solution depart from this practicality new
