Next, the sealed container 30 as a final product produced by using the sheet molding container 10 according to the present embodiment will be described with reference to FIGS. 3 and 4.

As shown in FIGS. 3 and 4, the sealed container 30 is manufactured by using the sheet molding container 10 described above. The sealed container 30 includes a flange portion 31, an accommodating portion 20 protruding from the flange portion 31, a flow path portion 25, a content liquid L contained in the accommodating portion 20, and a lid material 35 attached to the flange portion 31. And have.

Of these, the flange portion 31 is composed of a part of the flat portion 11 of the sheet forming container 10 described above, and is formed by cutting the flat portion 11 into a predetermined shape (see the alternate long and short dash line in FIG. 1). Further, the accommodating portion 20 and the flow path portion 25 have the same configuration as the accommodating portion 20 and the flow path portion 25 of the sheet molding container 10, respectively. A half-cut line 32 is formed on the flange portion 31 around the flow path portion 25 from the back surface side (opposite side of the lid member 35).

Further, the lid material 35 is sealed on the flange portion 31 over the entire circumference. Such a lid material 35 is composed of a laminate including at least a base material layer and a sealant layer. In this case, for example, the laminate may include a base material layer, an intermediate layer, and a sealant layer sequentially arranged from the outside.

The thickness of the lid material 35 can be, for example, 30 μm or more and 100 μm or less.

(Manufacturing method of sheet molded container and sealed container)
Next, a method for manufacturing the sheet molding container 10 and the sealed container 30 will be described with reference to FIGS. 5 to 9.

First, a sheet 10a made of a single-layer sheet or a multi-layer sheet constituting the sheet molding container 10 is prepared (see FIG. 5A).

Next, the plate-shaped sheet 10a is heated, and the heated sheet 10a is placed on the female mold 41. Next, the sheet 10a is pushed into the female mold 41 to a certain extent using the plug 42, and then the inside of the female mold 41 is evacuated to shape the sheet 10a into the shape of the female mold 41 (FIG. 5 (b). )reference).

By forming a sheet using the sheet 10a in this way, a sheet forming intermediate 10b having a predetermined shape can be obtained (see FIG. 5C). In this case, the sheet forming intermediate 10b includes a flat portion 11, a housing portion 20 protruding from the flat portion 11, and a bent portion 15, respectively. After that, the sheet forming intermediate 10b is cooled.

Next, cut lines 16 are formed by the cutting tools 43 at positions on both sides of the accommodating portion 20 in the second direction D2 of the flat portion 11 (see FIG. 5D). In this case, a part of the flat portion 11 is separated from each other into an inner portion 13 and an outer portion 12 via a cut line 16. The cut line 16 is also cut into the bent portion 15. In this way, the sheet molding container 10 shown in FIGS. 1 and 2 is obtained.

In this way, the sheet molding container 10 is manufactured through a heating step, a molding step, and a cooling step. Therefore, during the production of the sheet forming container 10, the sheet forming intermediate 10b (sheet forming container 10) contracts, and the degree of the contraction varies, which may cause a deviation in the pitch of the accommodating portion 20.

Subsequently, the half-cut line 32 (see FIG. 3) is formed in the sheet forming container 10 by using the half-cut device 50 shown in FIG.

The half-cut device 50 has a bottom surface portion 51, a top surface portion 52, and four columns 53 connecting the bottom surface portion 51 and the top surface portion 52. A plurality of blades 54 for forming the half-cut lines 32 are attached to the lower surface of the top surface portion 52. Further, a stage 55 that can move in the vertical direction along the support column 53 is provided between the bottom surface portion 51 and the top surface portion 52. A receiving jig 56 having a shape corresponding to the shape of the sheet forming container 10 is fixed to the upper surface of the stage 55.

When forming the half-cut line 32, first, the sheet forming container 10 is attached to the receiving jig 56 of the half-cut device 50 (see FIG. 7A). At this time, each accommodating portion 20 of the sheet forming container 10 is fitted into the corresponding convex portion 57 of the receiving jig 56. Therefore, if the sheet forming container 10 is contracted and the pitch of the accommodating portions 20 is deviated, it may be difficult to receive each accommodating portion 20 and fit it into the convex portion 57 of the jig 56.

In the present embodiment, as described above, the sheet molding container 10 has a bent portion 15 extending along the second direction D2. Further, the cut line 16 extends along the first direction D1 and cuts to the bent portion 15, respectively. Therefore, the bent portion 15 is elastically deformed in the first direction D1, so that the inner portion 13 moves relative to the outer portion 12. Along with this, each accommodating portion 20 can move along the first direction D1.

That is, as shown in FIG. 8, each accommodating portion 20 can move along the first direction D1 together with the inner portion 13. Therefore, each accommodating portion 20 moves from the state immediately after molding (virtual line) to the first direction D1 and moves to a position (solid line) that can be fitted to the convex portion 57 of the receiving jig 56. As a result, even if the sheet forming container 10 contracts and the pitch of the accommodating portions 20 is deviated, the positions of the accommodating portions 20 are appropriately adjusted, and the convex portions 57 of the jig 56 that receive the accommodating portions 20 Can be securely fitted to. On the other hand, the outer portion 12 does not elastically deform and substantially maintains the state immediately after molding.

After that, the stage 55 rises, and the receiving jig 56 and the sheet forming container 10 also rise accordingly (see FIG. 7B). At this time, the sheet forming container 10 comes into contact with the cutting tool 54, and the half-cut line 32 is accurately formed at a predetermined position of the flat portion 11.

Next, each accommodating portion 20 of the sheet forming container 10 is filled with the content liquid L (see FIG. 9A).

Next, a lid material 35 wound in a roll shape is prepared, and the lid material 35 is unwound from the roll. After that, the lid material 35 is sealed to the flat portion 11 (flange portion 31) around each accommodating portion 20 of the sheet forming container 10 (see FIG. 9B).

After that, the flat portion 11 is cut along the planned individual cutting line 33 (see FIG. 1), and the unnecessary portion of the flat portion 11 is removed to obtain the sealed container 30 shown in FIGS. 3 and 4 (FIG. 9). (C). At this time, each bent portion 15 is also separated from the sealed container 30.

In this way, also in the step of sealing the lid material 35 (see FIG. 9B) and the step of cutting the flat portion 11 along the planned individual cutting line 33 (see FIG. 9C), the bent portion 15 is also performed. Is elastically deformed in the first direction D1, and each accommodating portion 20 moves along the first direction D1. Therefore, even if the pitch of the accommodating portion 20 is deviated due to shrinkage, the position of the accommodating portion 20 can be adjusted in the step of sealing the lid material 35 and the step of cutting the flat portion 11. It is possible to accurately position the accommodating portion 20.

As described above, according to the present embodiment, the flat portion 11 is provided with the bent portion 15 extending along the second direction D2. In the flat portion 11, cut lines 16 are formed on both sides of the second direction D2 with respect to the accommodating portion 20, and the cut lines 16 are cut to the bent portions 15, respectively. Therefore, in the post-processing step of the sheet forming container 10 having the multiple accommodating portions 20, the position of the accommodating portion 20 can be moved along the first direction D1. As a result, even if the pitch of the accommodating portion 20 is displaced due to shrinkage, the deviation of the pitch of the accommodating portion 20 can be corrected in the post-processing step, and stable post-processing can be performed. .. As a result, it is possible to prevent the seal position from being displaced in the post-processing process and the position of the cutting tool 54 for inserting the half cut from being displaced from the predetermined position.

Further, according to the present embodiment, at least one bent portion 15 is arranged between the two accommodating portions 20 in the first direction D1. As a result, the pitch between the accommodating portion 20 and the accommodating portion 20 can be corrected in the post-processing step, the accommodating portion 20 can be accurately positioned, and more stable post-processing can be performed.

Further, according to the present embodiment, the bent portion 15 has a substantially V-shape in cross-sectional view. As a result, the V-shaped angle of the bent portion 15 can be changed, and the inner portions 13 located on both sides of the first direction D1 of the bent portion 15 can be moved along the first direction D1.

Further, according to the present embodiment, the flat portion 11 has a rectangular shape in a plan view, the long side 11a of the rectangle is parallel to the first direction D1, and the short side 11b of the rectangle is parallel to the second direction D2. Is. Thereby, when the sheet molding container 10 is manufactured, the position of the accommodating portion 20 can be adjusted along the longitudinal direction (first direction D1) of the flat portion 11 in which the degree of shrinkage is more likely to vary.

Further, according to the present embodiment, the flat portion 11 is separated into the outer portion 12 and the inner portion 13 by the cut line 16, and the inner portion 13 is relatively movable with respect to the outer portion 12. As a result, the position of the accommodating portion 20 arranged in the inner portion 13 can be adjusted along the first direction D1. On the other hand, since the outer portion 12 is substantially not deformed, it is possible to suppress a decrease in the rigidity of the sheet molding container 10 so as not to interfere with the handling and transportation of the sheet molding container 10.
