Description
Technical field
The present invention relates to basic lid, easy open cover and pop can, more particularly to a kind of pressure resistant type that can save material
Basic lid, easy open cover and the pop can with easy open cover.
Background technology
Easy open cover was come out in the last century 60's, was widely used in the auxiliary package of beverage can, beer can.Due to weight
Gently, small, the reusable plurality of advantages of waste material, easy open cover is widelyd popularize in worldwide, and forms Pang
Big production scale.With the continuous growth of the easy open cover market demand, easy open cover industry also rapidly develops, and competition also increasingly swashs
It is strong, therefore in order to economize on resources, reduce the needs that cost adapts to market competition, it is easy-to-draw to research and develop a kind of pressure resistance for saving material
Lid is not only Business survival and the needs of development, and is also the certainty of market economic development.
In the prior art, the CN201530522U Chinese inventions that one of representative structure can be found in.The patent disclosure
Easy open cover structure be：It is made of lid and the draw ring two parts being riveted on lid；From lid week on the lid cross section
While being followed successively by sealed cans region to center, immerse oneself in section, the capel arc section of steering, the upward capel that extend downwardly upwardly extend section
And horizontal center capping, immerse oneself in section and capel upwardly extend section between form annular groove；It is described to immerse oneself in section successively by oblique
To on immerse oneself in section, middle transition circular arc and it is vertical under immerse oneself in section and connect and compose.Above-mentioned patent formula is the reduction of blanking ruler
It is very little, but its pressure-resistant performance is still insufficient.
In the prior art, the two of representative structure can be found in the Chinese invention patent of CN100435997C.The patent
Disclosed cover body structure discloses：Section is immersed oneself in successively by inner wall section, junction, upper wall portion, wall part, upper wall portion, outer wall
Part connection composition.Above-mentioned patent formula pressure-resistant performance under the premise of material saving is also good, still, since it immerses oneself in section by more
Section is constituted, and is molded more difficult, the inflection point that wall part especially therein is formed here, especially difficult molding, the requirement to mold
Height, actual production are extremely difficult to Theoretical Design size.
So how under the premise of material saving and guarantee pressure resistance performance, simplifying structure reduces production difficulty, just becomes
One important topic.

Easy open cover, the easy open cover include basic lid and draw ring, the basic lid structure basic lid scheme as described above.
The present invention design principle be：This practicality is newly that will immerse oneself in section to be designed as only by first straight line section L1, the 4th circular arc
Section R4, the 5th arc section R5 compositions, the capel upwardly extend section and are made of second straight line section L2 and the 7th arc section R7, seemed
Seem the simple simplification of prior art CN100435997C, but it is to breach the design of this field all the time to be actually
Thinking limitation, previous easy open cover design field technical staff think always will immerse oneself in section add more inflection point could improve it is resistance to
Performance is pressed, and the present invention has formally broken this thinking limitation, and by the 5th arc section R5, capel arc section R6, the
The size selection and W1 of four arc section R4 is greater than or equal to 0.9 times of T1, and the T1 less than or equal to 1.15 times and limit
Surely immerse oneself in section immerse oneself in angle beta and capel upwardly extends the technical characteristics such as the angle of angle of strike α of section and finally unexpectedly reaches
The pressure-resistant performance equal or even slightly higher with prior art CN100435997C reaches so high resistance to so simplified structure
Pressure property performance this in this field be an important breakthrough.
The present invention compared with prior art the advantages of it is as follows：
1, in structure, immerse oneself in Duan Youliu, seven sections of straight lines or circular arc composition, the molding of prior art CN100435997C are stranded
Difficulty, the especially difficult molding of small arc-shaped inflection point especially therein, manufacture difficulty is obviously very high, it is difficult to ensure that size when actual fabrication
Precision；And the section of immersing oneself in of the present embodiment structure is only made of first straight line section L1, the 4th arc section R4, the 5th arc section R5, mistake
It crosses smoothly, it is significantly more in terms of molding, significantly reduce production difficulty and cost；
2, pressure-resistant performance, is proved with the analysis result of finite element：The present embodiment covers substantially（Labeled as SLAC）Resistance to pressure
Can CN100435997C compared to the prior art basic lid（Labeled as CDL）It is equal or even also slightly higher.

Setting the present embodiment covers substantially and prior art CN100435997C is covered substantially, involved material properties, material
Thickness, the conditions all same such as load mode, finite element method, size of mesh opening, cell type of model, it is unique it is different just
It is the structure covered substantially.
Carry out example with 200 lids, finite element analysis chart is as shown in Fig. 2, the present embodiment covers substantially（Labeled as SLAC）Pressure resistance
Value is 679.823KPa, and the basic lid of prior art CN100435997C（Labeled as CDL）Pressure voltage be 674.624
KPa。
Carry out example with 202 lids, finite element analysis chart is as shown in figure 3, the present embodiment covers substantially（Labeled as SLAC）Pressure resistance
Value is 649.35KPa, and the basic lid of prior art CN100435997C（Labeled as CDL）Pressure voltage be 639.175 KPa.
The left side vertical axis of described Fig. 2 and Fig. 3 represents pressure voltage, and right side vertical axis represents the volume covered substantially, and horizontal
Axis is the parameter of FEM calculation, so the peak value of specific curve just represents pressure voltage, and the shape of its curve, peak value occur
Morning and evening have no special meaning.
So can be seen that from the analysis result of above-mentioned finite element：The present embodiment covers substantially（Labeled as SLAC）Pressure resistance
The basic lid of performance CN100435997C compared to the prior art（Labeled as CDL）It is equal or even also slightly higher.
