Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. The container denoted by reference numeral 1 in FIGS. 6 to 9 is for containing a relatively small amount (one serving) of a solid-state fluid food material (fluid material) such as gelato or soft cream. The container 1 includes a container body 2 (cup-shaped member) and a lid 3 attached to the container body 2.

As shown in FIGS. 1 and 2, the container body 2 is obtained by molding a thin resin sheet, has shape retention, and is elastically deformable.
The container main body 2 integrally includes a bottom portion 10, a trunk portion 20 that is continuous with the bottom portion 10, and a flange portion 30 that is continuous with the opening periphery of the trunk portion 20. In the present embodiment, the bottom 10 has a regular hexagonal shape. The periphery of the opening of the trunk 20 has a regular hexagonal shape larger than that of the bottom 10. The opening periphery of the bottom part 10 and the trunk | drum 20 and the collar part 30 are parallel. Each side of the opening periphery of the body 20 is parallel to the corresponding side of the bottom 10. The cross-sectional area of the trunk portion 20 is the smallest in the vicinity of the bottom portion 10 and increases toward the opening periphery of the trunk portion 20.

The trunk portion 20 has a large number of linear broken lines and a large number of plane portions (surface portions) surrounded by the broken lines, and can be crushed. These broken lines include those that are broken in the mountains and those that are broken in the valleys as viewed from the outside of the container 1. The angle of these mountain breaks and valley breaks is 90 ° or more.
The trunk portion 20 has

portions

20a and 20b having different shapes that appear alternately every 60 ° along the circumferential direction.

Hereinafter, a broken line and a plane part are explained in full detail.
A mountain fold line (main mountain fold line) is formed on the boundary between the bottom 10 and the body 20, that is, on each side of the periphery of the bottom 10. These mountain fold lines are denoted by

reference numerals

21a and 21b corresponding to the

portions

20a and 20b, respectively.

The corners of the peripheral edge of the bottom 10 and the corresponding corners of the opening edge of the body 20 are connected by two continuous

mountain fold lines

22x and 22y (first and second auxiliary mountain fold lines). These

mountain fold lines

22x and 22y provide boundaries between the

parts

20a and 20b.
The

broken lines

21a, 21b, 22x, and 22y have round cross-sectional shapes and are indicated by double lines in the drawing.

The

mountain fold lines

22x and 22y are not connected in a straight line but intersect at an obtuse angle. This intersection (first intersection) is denoted by reference symbol P1. The intersection P1 is deviated in the circumferential direction from a virtual straight line connecting the corner of the bottom portion 10 and the corner of the opening edge of the body portion 20. That is, the intersection point P1 is biased away from the circumferential center of the part 20a and closer to the circumferential center of the part 20b. Thus, the

mountain fold lines

22x and 22y are shaped so as to protrude toward the portion 20b. The intersection point P1 is slightly deviated also in the radially inward direction of the body portion 20 with respect to the virtual straight line.

Six valley fold lines (second main valley fold lines) are formed at the periphery of the opening of the trunk portion 20, that is, at the boundary between the trunk portion 20 and the flange portion 30. These valley broken lines are denoted by

reference numerals

23a and 23b corresponding to the

portions

20a and 20b, respectively.

In the part 20a, a valley line 24a (main valley line) that is parallel to the mountain line 21a and the valley line 23a is formed. The valley line 24a is connected to a pair of intersection points P1 located on both sides of the part 20a.

Similarly, a valley fold line 24b (main valley fold line) parallel to the mountain fold line 21b and the valley fold line 23b is formed in the portion 20b. The valley fold line 24b is shorter than the valley fold line 24a, and both ends thereof are connected to a pair of intersection points P1 located on both sides of the portion 20b via a short mountain fold line 25 (third auxiliary mountain fold line). . P2 is attached to the intersection (second intersection) of the

broken lines

24b and 25.

The intersection P2 and the corners of the bottom 10 (points where the

broken lines

21a, 21b, and 22x intersect) are connected by a valley broken line 26x (first auxiliary valley folded line). The intersection point P2 and the corner of the opening edge of the trunk 20 (the point where the

polygonal lines

23a, 23b, and 22y intersect) are connected by a valley line 26y (second auxiliary valley line).

As shown in FIGS. 1B and 1C, the

broken lines

24a, 24b, 25 and the intersections P1, P2 are at the same height in the axial direction of the body portion 20 (positioned on a horizontal plane parallel to the bottom portion 10 and the flange portion 30). ) And closer to the bottom 10 than the center between the opening periphery of the bottom 10 and the body 20.

More specifically, as shown in FIG. 1A, the distance between the mountain fold line 21a and the valley fold line 23a when viewed from the axial direction of the trunk part 20 (the broken line when the trunk part 20 is crushed as described later) D is the distance between 21a and 23a; the distance between the

broken lines

21a and 23a in the radial direction of the body portion 20). As shown in FIG. 1B, the distance between the mountain fold line 21a and the valley fold line 24a (the width of the flat portion 27x described later) is Dx, and the distance between the

valley fold lines

23a and 24a (the width of the flat portion 27y described later) is Dy. If so, set the following relationship.
Dy−Dx = D (1)
Similarly, the distance Dx ′ between the mountain fold line 21b and the valley fold line 24b (the width of the plane portion 28x described later) and the distance Dy ′ (the width of the plane portion 28y described later) between the

valley fold lines

23b and 24b are also described below. Set to be related.
Dy′−Dx ′ = D (2)

The part 20a has two

rectangular plane portions

27x and 27y (first and second main surface portions). The plane portion 27x is surrounded by a pair of mountain fold lines 22x and a mountain fold line 21a and a valley fold line 24a that are parallel to each other, and has a trapezoidal shape with a short side on the bottom 10 side. The flat surface portion 27y is surrounded by a pair of mountain fold lines 22y and

valley fold lines

23a and 24a parallel to each other, and has a substantially rectangular shape.

The part 20b has two

rectangular plane portions

28x and 28y (first and second main surface portions). The plane portion 28x is surrounded by a pair of valley fold lines 26x and a mountain fold line 21b and a valley fold line 24b that are parallel to each other, and forms a trapezoid whose side on the bottom 10 side is long. The plane portion 28y is surrounded by

valley lines

23b and 24b that are parallel to the pair of valley lines 26y, and forms a trapezoid whose side on the bottom 10 side is short.

Further, the portion 20b has two

triangular plane portions

29x and 29y (first and second sub-surface portions) on both sides thereof. The plane portion 29x is surrounded by

mountain fold lines

22x and 25 and a valley fold line 26x. The plane portion 29y is surrounded by

mountain fold lines

22y and 25 and a valley fold line 26y.

The bottom portion 10 is formed with a regular hexagonal shallow convex portion 11 protruding into the body portion 20.
The flange portion 30 protrudes radially and outwardly from the opening periphery of the trunk portion 20 to form an annular shape, and is positioned on a plane orthogonal to the central axis of the trunk portion 20.

Although the outer peripheral edge of the annular flange 30 is circular, an overhanging portion 31 that protrudes radially outward is formed at one location. The circumferential position of the center of the projecting portion 31 in the circumferential direction coincides with the angle of the opening periphery of the body portion 20.

A circular ridge 32 is formed on the collar 20 over the entire circumference. Although this protrusion 32 protrudes in the opposite direction to the trunk portion 20, a portion 32a (selected portion) corresponding to the overhanging portion 31 is lower than the remaining portion 32b. In particular, see FIGS. 3A, 4A, and 5A.

After the container body 2 having the above-described configuration is filled with the fluid food material, the lid 3 is attached. The lid 3 is made of a soft sheet of resin, metal, paper, or a composite layer thereof, and has the same shape as the outline of the flange portion 20.
In this embodiment, the container body 2 is set in a state where the flange portion 20 is placed on the lower mold, and the heated upper mold is lowered to thermally bond the lid 3 to the flange portion 20.

In the mounting process of the lid 3, as shown in FIGS. 3A, 3B, 4A, 4B, 5A, and 5B, the top of the protrusion 32 is heat-sealed to the lid 3 while being crushed. As a result, the lid 3 is heat-sealed to the flange 20 over the entire circumference. By this heat fusion, an annular seal portion 4 corresponding to the protrusion 32 is obtained as shown in FIG. 6A. Since the portion 32a of the protrusion 32 is lower than the portion 32b, the fusion strength of the portion 4a corresponding to the portion 32a (the region indicated by rough hatching in FIG. 6A) in the seal portion 4 is low. The fusion strength of the part 4b corresponding to the part 32b (a region indicated by dense hatching in FIG. 6A) is high. However, the part 4a has a fusion strength sufficient to ensure a good sealing property in the storage and transport states.

When the upper mold has a cylindrical shape, auxiliary seal portions 4c indicated by light ink in FIG. 6A are formed on the inside and outside in the radial direction of the seal portion 4. The adhesion strength of the auxiliary seal portion 4c is very weak and the sealability is not sufficiently guaranteed, and the auxiliary seal portion 4c is peeled off with a slight force.

The lid 3 has a knob portion 3a corresponding to the protruding portion 31 of the flange portion 30 of the container body 2. This knob portion 3 a is not fused to the overhang portion 31.

The container 1 filled with the fluid food material 2 and sealed with the lid 3 as described above is transported from the factory to the store. At the store, after receiving the order, the grip portion 3a of the lid 3 is pinched and peeled off from the collar portion 30 to eliminate the seal state of the selected portion 4a of the seal portion as shown in FIG. A peeling region 4a ′ from which the flange 30 is peeled is formed. At this time, since the peeling operation is performed at the portion 4a having a relatively low fusion strength, workability is good.

Next, as shown in FIG. 7, the container 1 is set upside down (with the bottom 10 facing up) on the base 5 of the extruder. In the set state of the container 1, the lid 3 hits the base 5 and the peeling area 4 a ′ is on the bottom.

Next, as shown by an arrow in FIG. 7, a pressing member (not shown) of the extruder is pressed against the bottom 10 of the container 1.
Then, the trunk | drum 20 of the container 1 is crushed, the fluid food material with which it was filled receives the pressing force, is extruded little by little from said peeling area | region 4a ', and is supplied to the individual food containers 6, such as a cone. In the above, since the discharge port constituted by the peeling region 4a ′ is flat, fluid food can be supplied to the individual food container 6 as if it were arranged with a spatula.

In this embodiment, before setting the container 1, the knob 3a of the lid 3 is pinched and a part of the lid 3 is peeled off. However, this operation may be omitted. That is, the container 1 is kept in the sealed state (the state shown in FIG. 6A) around the entire circumference of the collar portion 30 in the same manner as described above (with the selected portion 4a of the seal portion 4 facing down) to the extruder. set. In this case, the flowable food material that has received a pressing force when crushing the body portion 20 first peels the lid 3 from the flange portion 30 at the portion 4a having a low fusion strength, and the separation region 4a ′ of FIG. Will form. When the pressing force is further applied, the fluid food material is pushed out from the peeling region 4a '.

When the pressing force is applied to the bottom portion 10 as described above, the bottom portion 10 translates in the axial direction of the trunk portion 20 toward the opening periphery of the trunk portion 20. At this time, the shape of the bottom portion 10, the peripheral edge of the opening of the body portion 20, and the shape of the flange portion 30 do not change, and only the body portion 20 is deformed and crushed. Hereinafter, the deformation of the body portion 20 will be described in detail with reference to FIGS.

As the bottom portion 10 moves in the axial direction, the crossing angle at the

valley fold lines

23a and 23b increases and finally becomes approximately 180 °, but all

other fold lines

21a, 21b, 22x, 22y, 24a, 24b, The crossing angle at 25, 26x, and 26y decreases and finally becomes approximately 0 °.

The two

rectangular plane portions

27x and 27y of the portion 20a are folded along with a decrease in the intersection angle at the valley fold line 24a, and the plane portion 27x becomes a part of the bottom portion 10 along with a decrease in the intersection angle at the mountain fold line 21a. Overlap.
Similarly, the two

quadrangular plane portions

28x and 28y of the portion 20b are folded along with a decrease in the intersection angle at the valley fold line 24b, and the plane portion 28x is folded along the decrease in the intersection angle at the mountain fold line 21b. Overlapping part.
The

valley fold lines

24a and 24b move toward the back, that is, toward the central axis of the trunk portion 20.

The triangular planar portion 29x overlaps with the side of the rectangular planar portion 28x as the intersection angle at the valley fold line 26x decreases, and the side of the planar portion 27x decreases as the intersection angle at the mountain fold line 22x decreases. Overlapping.
Similarly, the triangular plane portion 29y overlaps with the side portion of the rectangular plane portion 28y as the intersection angle at the valley fold line 26y decreases, and the plane portion 27y decreases as the intersection angle at the mountain fold line 22y decreases. Overlap under the side.

Further, the

triangular plane portions

29x and 29y are folded together so as to sandwich the side portions of the

rectangular plane portions

27x and 27y as the crossing angle at the mountain fold line 25 decreases.

As described above, the pressing force is used to increase / decrease the crossing angle at the broken line, and the

flat portions

27x, 27y, 28x, 28y, 29x, 29y substantially maintain their shapes while minimizing deformation. It folds as it is. As a result, the trunk portion 20 can be crushed until it becomes substantially flat, and the contained fluid food can be pushed out almost without any surplus.
In addition, the shallow convex part 11 of the said bottom part 10 is located in the space area | region which is not occupied by the

plane parts

27x, 27y, 28x, 28y, 29x, 29y folded as mentioned above, and also by this, fluid foodstuffs Remaining in the container 1 can be minimized.

Hereinafter, other embodiments of the present invention will be described. In these embodiments, constituent parts corresponding to the preceding embodiments are assigned the same reference numerals and description thereof is omitted.

FIG. 10A, FIG. 10B, and FIG. 11 show a container according to a second embodiment of the present invention. As shown in FIG. 10A, the peripheral edge of the bottom 10A of the container main body 2A of this container has a regular pentagon, and the opening peripheral edge of the trunk 20A also has a regular pentagon. Each side of the regular pentagon of the bottom portion 10A and the corresponding side of the regular pentagon of the trunk portion 20A are parallel to each other as in the first embodiment.

In the trunk portion 20A, the five portions 20c arranged side by side in the circumferential direction have the same shape, which is different from the first embodiment. Each part 20c has two

rectangular plane portions

28x and 28y (first and second main surface portions) and two

triangular plane portions

29x and 29y (first and second sub-surface portions). Yes.

In the figure, six mountain fold lines (main mountain fold lines) at the boundary between the bottom 10A and the trunk 20A are denoted by reference numeral 21a, and six valley fold lines (second main valley fold lines) at the boundary between the trunk 20A and the buttock 30 are shown.

When the pressing force is applied to the cap 20, the body portion 20 is crushed so that all the flat portions are folded without being distorted, so that the inner volume can be crushed until it becomes substantially zero. When the pressing force is released, the original shape or a shape close to the original shape can be easily restored.

The present invention is not limited to the above embodiment, and various aspects can be adopted.
The bottom of the cup-shaped member, the first and second main surface portions, and the first and second sub surface portions can be made substantially flat if they are slightly distorted and overlapped. In particular, when the cup-shaped member is thin and deforms without applying a large force, the tolerance of distortion increases. From this point of view, the polygons of the opening periphery of the trunk portion and the periphery of the bottom portion do not have to be polygonal in a strict sense, and include those whose sides are not curved but gently curved. The broken line may not be strictly linear but may be gently curved. In this case, the first and second main surface portions, the first and second sub surface portions may be curved surfaces, and the sides thereof may be curved. Further, the above formulas (1) and (2) may not be set strictly, and include an allowable range of about 20%, for example.
