Omit top seal.In addition, the microwave stove heat of package body 19, and then, 20 heated temperature of object in custody rises and produced
Steam.
Fig. 5 is the front section view for cutting off the package body 19 shown in Fig. 4 along the 1st central axis L 1, and Fig. 6 is by Fig. 4
The side sectional view that shown package body 19 forms along the cut-out of the 2nd central axis L 2.
As shown in Figures 5 and 6, it is housed in object in custody 20 in resettlement section 14, and covers resettlement section 14 and object in custody
20 mode configures top seal 21.
Also, the surrounding wall portion 13 of part overlapping with the 1st central axis L 1 in the surrounding wall portion 13 shown in Fig. 4 is shown in Fig. 5.Separately
Outside, the surrounding wall portion 13 of part overlapping with the 2nd central axis L 2 in the surrounding wall portion 13 shown in Fig. 4 is shown in figure 6.That is, with the 2nd
The surrounding wall portion 13 of the overlapping part of central axis L 2 forms bending section C.
Moreover, top seal 21 engages with the all-round of lip portions 15, therefore resettlement section 14 is by top seal 21
Sealing.Now, combined throughout the all-round of lip portions 15, top seal 21 in a manner of with roughly the same bond strength.

Fig. 8 shows the result of a quarter model emulation, and its confirmation makes the resettlement section 14 sealed by top seal 21
When internal pressure rises, it is applied to it and mutagens shape in which way for the stress of package body 19.It is for the bag shown in Fig. 4
Body 19 is filled, as shown in figure 8, four of the package body 19 for utilizing the part with the 1st central axis L 1 and the segmentation of the 2nd central axis L 2
/ mono- model, implement emulation.But object in custody 20 is omitted on analog simulation.In addition, in simulation, for the 1st central axis L 1
And the 2nd each in central axis L 2, divisional plane are assumed to unopened free end.Because the shape of package body 19 is on the 1st
Central axis L 1 is symmetrical, and be also symmetrical on the 2nd central axis L 2, therefore for being divided into the package body 19 of a quarter
Analog result is applicable to undivided package body 19.
In Fig. 8, the shape of the container for packing 11 before the internal pressure rising of resettlement section 14 is represented with dotted line, make
Shape after the internal pressure of resettlement section 14 rises is represented with solid line.
The result for implementing simulation is shown, in the internal pressure by the resettlement section 14 for making to be sealed by top seal 21
Rise, top seal 21 is deformed in a manner of expanding upward, and surrounding wall portion 13 also deforms.It is bead that its origin cause of formation, which is contemplated that,
The all-round drawing tension by the top seal 21 from deformation in portion 15, and rise resettlement section 14 internal pressure for
The mass action of surrounding wall portion 13.
When the internal pressure of resettlement section 14 rises, surrounding wall portion 13 beyond bending section C and bending section C is respectively with to resettlement section
14 mode deforms, and bending section C deflection is big compared with the deflection of the surrounding wall portion 13 beyond the C of bending section.This display, bending section C
It is more easily deformed compared with all wall portions 13 beyond the C of bending section.In addition, it can understand, the maximum deformation of deflection in surrounding wall portion 13
Maximum point M is measured to be formed in the C of bending section.Moreover, deflection maximum point M, in top seal 21 and the interface of lip portions 15
/ in, the part overlapping with the 2nd central axis L 2 positioned at the bending section C shown in Fig. 4.In addition, it will also be understood that, stress concentration
In deflection maximum point M, deflection maximum point M lip portions 15 are compared with other lip portions 15, by more powerful power.
If by the package body 19 shown in Fig. 4 with microwave stove heat, because of the object in custody 20 that is housed in resettlement section 14
Temperature rises, and steam is produced from object in custody 20.Now, because of resettlement section 14 by top seal 21 connecing towards lip portions 15
Close and sealed, therefore by producing steam from object in custody 20 and rising what is be heated along with the temperature of object in custody 20
Gas expansion in resettlement section 14, the internal pressure of resettlement section 14 are gradually increasing.
As shown in FIG. 9 and 10, along with resettlement section 14 internal pressure P rising, top seal 21 is with towards resettlement section 14
Top expansion mode deform.Moreover, the internal pressure P risen equably acts on for surrounding wall portion 13 is overall, thereby surrounding wall portion 13
Deformed to resettlement section 14.
The result of simulation for above-mentioned package body 19 is, as shown in figure 8, deflection is most in the surrounding wall portion 13 of impartial stress
Big deflection maximum point M is formed in the C of bending section.
Therefore, as shown in FIG. 9 and 10, deformed because of the internal pressure P of the drawing tension from top seal 21 and rising
Surrounding wall portion 13 in, identical with the result of simulation, bending section C deforms bigger compared with the surrounding wall portion 13 beyond the C of bending section.Moreover, such as
Shown in Figure 10, the maximum deflection maximum point M of deflection is formed in the C of bending section in surrounding wall portion 13.
Further, since deflection maximum point M with simulate result it is identical, formed with the weight of the 2nd central axis L 2 shown in Fig. 4
In folded bending section C, therefore as shown in Figure 10, a pair of deflection maximum point M are pressed from both sides formed across resettlement section 14 respectively.
As shown in fig. 7, before the heating of package body 19, top seal 21 is somebody's turn to do from the part engaged with lip portions 15 is relative
Extend to 15 non-flexing of lip portions.By the way that package body 19 is heated, top seal 21 deforms, and surrounding wall portion 13 is all-round to receipts
Appearance portion 14 deforms, thus top seal 21 by from the part that lip portions 15 engage relative to the lip portions 15 with specific
Flexion angle mode flexing.
Figure 11 is the enlarged drawing near display Fig. 9 lip portions 15.By the package body 19 after deformation in the 1st central axis L 1
Position cut-out section in, top seal 21 after deformation by from the part that lip portions 15 engage relative to the lip portions
15 in a manner of with flexion angle θ 1 flexing.
Figure 12 is to show the enlarged drawing near Figure 10 lip portions 15.By the package body 19 after deformation in the 2nd central shaft
In the section of L2 position cut-out, top seal 21 after deformation by from the part that lip portions 15 engage relative to the bead
The flexing in a manner of with flexion angle θ 2 of portion 15.
Now, deflection maximum point M deflection is big compared with the surrounding wall portion 13 beyond deflection maximum point M, therefore Figure 12 institutes
The flexion angle θ 2 shown is big compared with the flexion angle θ 1 shown in Figure 11.
In addition, because the flexion angle of top seal 21 becomes big, lip portions 15 are by the tension from top seal 21
In power, become big relative to the vertical component of lip portions 15.
As shown in figure 11, the lip portions 15 of part overlapping with the 1st central axis L 1 in lip portions 15, by prominent relative to this
The vertical component Fv1 in edge 15.Also, as shown in figure 12, the lip portions of the part overlapping with the 2nd central axis L 2 in lip portions 15
15, i.e. deflection maximum point M lip portions 15, by relative to the vertical component Fv2 of the lip portions 15.
As described above, the flexion angle θ 2 shown in Figure 12 is big compared with the flexion angle θ 1 shown in Figure 11, therefore shown in Figure 12
Component Fv2 is big compared with the component Fv1 shown in Figure 11.
Rise with the internal pressure of resettlement section 14, the deflection of top seal 21 and the deformation quantitative change of surrounding wall portion 13 are big, top
The flexion angle of portion's seal 21 also becomes big.And then because the drawing tension of top seal 21 also becomes big, therefore relative to bead
The vertical component in portion 15 becomes big.Stripping of the component for top seal 21 acts, and one reaches specific peeling force, top
Portion's seal 21 is just peeled off from lip portions 15.
As shown in FIG. 9 and 10, if the lasting risings of internal pressure P of resettlement section 14, then the deflection of top seal 21 and
The deflection of surrounding wall portion 13 also becomes big.Now, it is identical with the result of simulation, deflection maximum point M deflection in surrounding wall portion 13
It will become much larger, and the flexion angle θ 2 shown in Figure 12 also becomes big.Furthermore because the drawing tension of top seal 21 also becomes big,
Therefore will be persistently close to specific peeling force relative to the vertical component Fv2 of deflection maximum point M lip portions 15.
In this way, the internal pressure P of resettlement section 14 exceedes setting value, the drawing tension of amount maximum point M to be deformed top seal 21
Component Fv2 reach specific peeling force, a part for top seal 21 is just shelled from deflection maximum point M lip portions 15
From steam is discharged from resettlement section 14.Although also, it is respectively formed with deflection most in a pair of curved portion C of container for packing 11
A little bigger M, but it is right due to the shape caused by the manufacturing tolerance of container for packing 11 and the heterogeneity of intensity and top seal 21
It is first-class in the inequality of the bond strength of lip portions 15, in a pair of deflection maximum point M either one, top can be started in advance and sealed
The stripping of part 21.Then, if steam is discharged between the top seal 21 and lip portions 15 peeled off, then resettlement section 14 is interior
Pressure P will be dramatically reduced.
In previous package body, because container for packing is sealed, therefore first top must be sealed before heating
The state for offering passage is peeled off and formed to a part for part, then just by package body with microwave stove heat.For that purpose it is necessary to from
A part for top seal is peeled off in grasping part set by top seal, labor intensive and time.
In contrast, in the package body 19 that embodiment 1 is related to, will packaging in the state of resettlement section 14 is sealed
Body 19 is increased beyond setting value with microwave stove heat, by the internal pressure of resettlement section 14, top seal 21 will automatically peel off with
Causing the internal pressure of resettlement section 14 reduces.Therefore, the internal pressure for not having resettlement section 14 continues rising up to object in custody 20 in micro-wave oven
The degree dispersed in stove, the misgivings being dirty are not had in the stove of micro-wave oven.Therefore, do not expend before heating and seal top
The labour and time that a part for part 21 is peeled off, you can by the heating and regulating of object in custody 20.
In addition, object in custody 20 is added ripe conditioning to one of top seal 21 in the state of resettlement section 14 is by sealing
Divide and automatically strip.If resettlement section 14 is sealed, the steam containing heat energy will not be unnecessarily discarded to outside package body 19, and can
Heating and regulating is carried out with pressure more than atmospheric pressure in the state of steam is full of, therefore required for can also shortening heating and regulating
Time.
