Description
Technical field
The utility model relates to a kind of easy open cover, particularly a kind of pressure resistant type easy open cover and a kind of easy-to-draw tank body including this easy open cover.
Background technology
Easy open cover generally includes capping and lid frame in being roughly plane, capping is processed line of weakness and forms unlatching tongue area, be provided with on the capping opening tongue area be installed with draw ring in correspondence.Along with filling food, the developing rapidly of beverage Industry, pop can and easy open cover are also developed rapidly.In order to economize on resources, reduce costs, lid aluminium thinning lightweight becomes the inexorable trend of this area.But, in actual applications, often occur causing because of lid aluminium thinning lightweight the problem covering withstand voltage deficiency.In production practice, find in subsequent handling, use the pop can of aluminium thinning lightweight when canned, easily produce bulging tank phenomenon, its reason is mainly because the compressive resistance of lid is inadequate.Aluminium is thinning, the intensity of lid reduces, and withstand voltage corresponding reduction, causes it can not meet the canned demand of pop can.Develop a kind of while aluminium thinning lightweight, also can ensure that the easy open cover of compressive resistance becomes the art technical matters urgently to be resolved hurrily.
Utility model content
In order to overcome above-mentioned deficiency, the purpose of this utility model is to provide a kind of easy open cover with higher compressive resistance, also provides a kind of easy-to-draw tank body containing this easy open cover simultaneously.
The utility model is for reaching its object, the technical scheme adopted is as follows: the withstand voltage easy open cover of a kind of rear vault structure, comprise capping, lid frame and be fixedly arranged on the draw ring of capping, unlatching tongue area is provided with on capping surface, the capel caved in by one between described capping with lid frame is connected, degree of depth of its depression of capel is 2.3 ~ 2.6mm, and described capping arches upward in cambered surface, and the distance along place plane under described capping vault and capping is 3.6mm ~ 4.0mm.
As a kind of specific embodiment, connected by transition arc between described capel and described capping.
Preferably, described transition arc home position and through described cover center longitudinal axis shortest distance be 50.7-50.8mm.
As a kind of specific embodiment, the bottom surface of described capel depression forms ring-type arc surface.
A kind of easy-to-draw tank body, comprise open-topped tank body and the easy open cover for sealing tank bodies top opening, easy open cover is the withstand voltage easy open cover of rear vault structure mentioned above.
The technical scheme that the utility model provides has following beneficial effect:
The withstand voltage easy open cover of rear vault structure that the utility model provides, the capel caved in by one between its capping with lid frame is connected, the degree of depth of its depression of capel is set to 2.3 ~ 2.6mm, capping arches upward in cambered surface, and the distance along place plane under capping vault and capping is 3.6mm ~ 4.0mm, compared with traditional easy open cover, easy open cover of the present utility model adds the area of thrust surface of capping, and compressive resistance is also improved.Easy open cover of the present utility model is compared with existing traditional easy open cover, and its compressive resistance can be promoted to more than 650KPa by common 630KPa, and what not only meet national standard is greater than 610KPa, and more can meet the filling requirement of pop can.

Fig. 3 is the partial schematic diagram of Fig. 2.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The utility model provides a kind of rear vault structure withstand voltage easy open cover, see Fig. 1 ~ 3, comprises capping 2, lid frame 1 and is fixedly arranged on the draw ring 4 of capping 2, forms a unlatching tongue area 5 being convenient to open on capping 2 surface by processing line of weakness.In the prior art, draw ring 4 is fixed on capping 2 usually through rivet, and draw ring 4 is positioned at unlatching tongue area 5 in the fixed position of capping 2.The withstand voltage easy open cover of rear vault structure of the present utility model, is linked up the two by the capel 3 of a depression between its capping 2 and lid frame 1.Capel 3 is formed by punch process, and see Fig. 2-3, the degree of depth h that capel 3 caves in is 2.3 ~ 2.6mm, and the best is 2.5mm.Arch upward in the middle part of capping 2, make capping entirety arch upward in arc surfaced, along the distance of place plane under capping 2 vault and capping, also namely the height of vault is preferably more than 3.6mm, is more preferred from 3.6 ~ 4.0mm.Joining place between capel 3 and capping 2 is arc transition, namely, connected by transition arc 32, and the home position of this transition arc 32 and through capping 2 center longitudinal axis (dotted line see shown in Fig. 2) shortest distance be preferably 50.7mm-50.8mm.Its bottom surface 31 to lower recess of capel 3 forms ring-type arc surface.The withstand voltage easy open cover of rear vault structure of the present utility model, the capping 2 more existing flush type capping area of thrust surface of its certain altitude that arches upward are larger, and have the intensity of materials processing sclerosis generation.
Find in practice, the thin aluminium being thinned to 0.254mm is adopted to prepare easy open cover, after the degree of depth of capel 3 is deep to 2.3 ~ 2.6mm from 2.0mm punching press, the home position of the transition arc 32 between capel 3 and capping 2 and through capping 2 center longitudinal axis shortest distance drop to 50.7mm by original 50.9mm, that is, this its home position of transition arc 32 moves to cover center; Meanwhile, after capel 3 punching press is 2.3 ~ 2.6mm to its degree of depth h, capping 2 also becomes from plane the arc surfaced arched upward.Its final compressive resistance of this easy open cover rises to more than 650KPa by existing 630KPa, and what not only meet national standard is greater than 610KPa requirement, more can meet the canned requirement of pop can.
The withstand voltage easy open cover of rear vault structure that the utility model provides can be applicable in easy-to-draw tank body, existing easy-to-draw tank body has an open-topped tank body for the material such as containing foodstuff or beverage, easy open cover is then located at tank bodies top and is sealed its open top, and this easy open cover can adopt the withstand voltage easy open cover of rear vault structure of the present utility model as described above.The structure of its tank body of easy-to-draw tank body is prior art, does not repeat them here.
The utility model is not limited to above-mentioned embodiment, every spirit and scope of the present utility model are not departed to various change of the present utility model or modification, if these are changed and modification belongs within claim of the present utility model and equivalent technologies scope, then the utility model also means that comprising these changes and modification.
