In the range of be formed as flat shape.In addition, there is the 1st heat-fused portion 81B top view to be corresponding with steam discharge unit 25
Position towards outside occlusion and for even shape W shapes portion 71.
1st heat-fused portion 81B is formed as by end socket 90 (hot plate) being pressed into the flange part 22 of container body 80
Banding.End socket 90 is configured to, and has than the position in addition to W shapes portion 71 more with W shapes portion 71 (easily peelable portion) corresponding position
Thin thickness (lower height when being seen downward from the baseline on the top of end socket 90).Specifically, W shapes portion 71 is with as shown in Figure 11
As be configured to the end socket 90 of thermal welding corresponding with the form in the W shapes portion 71 of such as embodiment 2 and formed.Certainly,
Can be corresponding with the form in the W shapes portion 27 of embodiment 1.In fig. 11, assign and representing and 71 pairs of W shapes portion on end socket 90
The symbol at the position for the W shapes structure 71 ' answered is illustrated.That is, end socket 90 is by the point 71a ' of outside two, 71a ', inner central
Point 71b ', the root 71c ' of inner side two, 71c ', two point 71a ' of link outside, 71a ' and inner central point 71b '
Central two edge 71d ', 71d ', link two point 71a ' of outside, 71a ' and the root 71c ' of inner side two, 71c ' root both sides
Portion 71e ', 71e ' are constituted.By the end socket 90 being pressed into across cover 50 the flat upper surface of flange part 22, in flange
The upper surface in portion 22 forms the W shapes portion 71 with the welding of cover 50.
By the way that end socket 90 is pressed into flange part 22, W shapes portion 71 is formed as two roots on the inside of the strength ratio with thermal welding
71c, 71c weak outside two point 71a, 71a.In addition, being formed as two root 71c, 71c on the inside of the strength ratio with thermal welding
Weak inner central point 71b.That is, the W shapes portion 71 of embodiment 4 is obtained so that the W shape structures of end socket 90 are inverted above and below 71 '
State formed.
That is, central two edge 71d, 71d for linking outside two point 71a, 71a and inner central point 71b is relative
In horizontal plane there is the ground of tilt angle theta 2 to be tilted upward towards outside.By constituting in this wise, the thermal welding of cover 50
To container body 20 flange part 22 when, the degree that outside two point 71a, 71a are heating-fusion bonded is than inner central point 71b
Gently, so being more prone to peel off.
In addition, in order that outside two point 71a, 71a are more easily peelable, make on the outside of link two point 71a, 71a and
Inner side two root 71c, 71c edge 71e, 71e of root two with respect to the horizontal plane have the ground of tilt angle theta 1 still towards outer lateral
Inclined upward.The tilt angle theta 1 is configured to the angle of inclination bigger than the tilt angle theta 2 of central two edge 71d, 71d.By this
Constitute sample, when cover 50 being heat fused to the flange part 22 of container body 20, clip two point 71a, 71a's of outside
Two edge 71d, 71d of center are different with the intensity of the thermal welding at edge 71e, 71e of root two, so for the point of outside two
The stress of 27a, 27a vapour pressure is more concentrated, and is more prone to peel off.
Thus, in the same manner as embodiment 1 and embodiment 2, by suppressing the width that W shapes portion 71 is peeled off from inside facing outward side
Degree, adjusts the discharge rate of steam, and the stewing steaming effect of content is maintained.Further, since the distance to the end of cover is short, steam
The generation of buzzer is suppressed when gas is discharged.It is additionally, since the water droplet in the decompression after steam is discharged and is not detained in W shapes
The part that the V-arrangement in center is surrounded, steam is discharged, it is possible to achieve prevent what container body 20 from deforming by the steam that inside is full of
Effect.
(variation)
In embodiment 1 into embodiment 4, easily peelable portion is towards the W shapes portion 27 or W shapes portion of outside occlusion by top view
71 constitute, but be applicable the present invention when, its shape be not limited to as outside two point 27a, 27a or point 71a of outside two,
71a turns into the W shapes portion of cusp-shaped towards outside like that (comprising the V-shape portion that Outer tips portion is 1).Even if in addition, for example easy
Stripping portion is made up of the U-shaped portion towards outside occlusion, and Outer tips portion is formed by the part of arc-shaped, can also be obtained and each reality
Apply the same effect of mode.
(conclusion)
More than, the present invention is illustrated with embodiment, but the technical scope of the present invention is not limited to what the embodiment was recorded
Scope, this is self-evident.Those of ordinary skill in the art understand, can add various in said embodiment
Change is improved.In addition, from the record of the scope of claims it will be appreciated that the side that additional such change or improvement are obtained
