[Container body 1]
The container body 1 accommodates the object to be packaged 7 in the pouch container package B1 in a hermetically sealed state. The container body 1 has a pair of body sheets 11 and a top sheet 12. The specific configuration of the container body 1 in the pouch container package A1 and the pouch container package B1 is not limited at all. The container body 1 may have only a pair of body sheets 11 and a top sheet 12, or may further have a side gusset sheet, a bottom gusset sheet, and the like.

The pair of main body sheets 11 overlap in the y direction. The shape and size of the pair of main body sheets 11 are not particularly limited. As the shape of the main body sheet 11, various shapes such as a rectangular shape and a polygonal shape are appropriately selected, and in the present embodiment, the shape is substantially rectangular as a whole. The main body sheet 11 is configured so that the closed state of the container main body 1 can be maintained when the pouch container package B1 is unused, and does not have a through hole or a cut portion leading to the inside. The pair of main body sheets 11 constituting the container main body 1 are not limited to those made of sheet materials that are separate from each other. For example, a pair of main body sheets 11 overlapping in the y direction may be formed by flatly folding a tubular sheet formed by joining both ends of one sheet material in the width direction.

The top sheet 12 closes the top side of the pair of main body sheets 11 (upper side in the z direction in FIGS. 1 and 3). The shape and size of the top sheet 12 are not particularly limited. As the shape of the top sheet 12, for example, various shapes such as a rectangular shape, a polygonal shape, a circular shape, and an elliptical shape are appropriately selected, and in the present embodiment, the shape is a substantially octagonal shape as shown in FIG. The top sheet 12 is configured so that the closed state of the container body 1 can be maintained when the pouch container package B1 is unused, and does not have a through hole or a cut portion leading to the inside. Further, as shown in FIG. 4, the top surface sheet 12 has a flat portion 125. The flat portion 125 is a portion that is flat in a state where the fixing portion 3 described later is fixed.

The pair of main body sheets 11 and top sheet 12 are usually composed of a resin film. The resin film is required to have basic performance as a package such as impact resistance, abrasion resistance, and heat resistance. Further, since the seal portion 17 described later is usually formed by heat sealing, the sheet is also required to have heat sealing properties. Further, the spout 2 described later is fixed to the top sheet 12 by, for example, ultrasonic welding. As the sheet, a multi-layer sheet having a base film layer and a sealant film layer that imparts heat-sealing properties is suitable, and when high gas barrier properties and light-shielding properties are required, the base film layer and the sealant film layer are required. It is preferable to provide a barrier layer between the two. The base film layer itself may be provided with a barrier property. In this case, the barrier layer is used as the base film layer, and the multi-layer sheet has the barrier layer and the sealant film layer.

As shown in FIG. 8, in the present embodiment, a case where the main body sheet 11 has a structure in which the base film layer 101, the sealant film layer 102, and the barrier film layer 104 are laminated will be described as an example. Further, as shown in FIG. 9, a case where the top surface sheet 12 has a structure in which the base film layer 101, the sealant film layer 102, the sealant film layer 103, and the barrier film layer 104 are laminated will be described as an example.

The base film layer 101 is interposed between the sealant film layer 102 and the sealant film layer 103. The barrier film layer 104 is interposed between the base film layer 101 and the sealant film layer 102. The barrier film layer 104 may be interposed between the base film layer 101 and the sealant film layer 103. Further, the barrier film layers 104 may be provided on both sides of the base film layer 101. In FIG. 10, the upper side in the z direction in the figure is the outer surface side, and the lower side is the inner surface side.

In such a hollow portion, for example, of the sealant film layer 103, the base film layer 101, the barrier film layer 104, and the sealant film layer 103 constituting the top sheet 12 shown in FIG. 9, only the base film layer 101 receives laser light. Examples include those that have been altered by the irradiation of the film to form cavities. However, from the viewpoint of protecting the object to be packaged 7, it is preferable that the easy-to-cut line 120 does not penetrate the barrier film layer 104. The easy-to-cut line 120 can be formed, for example, by irradiating the material sheet of the top sheet 12 with laser light from the sealant film layer 103 side. The location where the easy-to-cut line 120 is provided and its function will be described later.

Here, the constituent materials of the base film layer 101, the sealant film layers 102 and 103, and the barrier film layer 104 will be illustrated. Lamination of each of these layers can be performed by a conventional laminating method, for example, coextrusion lamination, dry lamination with an adhesive, thermal lamination in which a heat-adhesive layer is sandwiched and heat-bonded.

Examples of the film constituting the base film layer 101 include polyester (polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polybutylene terephthalate (PBT), polycarbonate (PC), etc.), polyolefin (polyethylene (PE), polypropylene). (PP), etc.), Polyethylene (Nylon-6, Nylon-66, etc.), Polyacrylonitrile (PAN), Polyethylene (PI), Polyvinyl Chloride (PVC), Polyvinylidene Chloride (PVDC), Polymethylmethacrylate (PMMA), Examples thereof include a one-layer or two-layer or more stretched or unstretched film composed of polyether sulphon (PES) or the like.

The films constituting the sealant film layers 102 and 103 include low density polyethylene (LDPE), linear low density polyethylene (LLDPE), ethylene-propylene copolymer (EP), unstretched polypropylene (CPP), and biaxially stretched film. A layer composed of nylon (ON), ethylene-olefin copolymer, ethylene-acrylic acid copolymer (EAA), ethylene-methacrylic acid copolymer (EMAA), ethylene-vinyl acetate copolymer (EVA), etc. Alternatively, a stretched or unstretched film having two or more layers can be exemplified.

The barrier film layer 104 is a metal thin film such as aluminum, a resin film such as vinylidene chloride (PVDC) or ethylene-vinyl alcohol copolymer (EVOH), or an arbitrary synthetic resin film (for example, a base film layer). A film obtained by vapor-depositing (or sputtering) an inorganic oxide such as aluminum, aluminum oxide or silica can be exemplified.

As a preferable configuration example of the top sheet 12 having the easy-to-cut line 120 composed of the above-mentioned hollow portion, a polyethylene-based sealant film layer (sealing film layer 103), a polyester-based or polyamide-based base film layer (base film) Examples thereof include a laminated film including at least four layers of a layer 101), a metal thin film (barrier film layer 104), and a polyethylene-based sealant layer (sealant film layer 103).

As shown in FIGS. 4 to 7, the strip-shaped portion 6 is provided between the thick portion 322 of the fixing portion 3 and the flange portion 42 of the rotating portion 4. In the illustrated example, the strip-shaped portion 6 surrounds the first tubular portion 41 and the outer tubular portion 43 of the rotating portion 4 from the outside in the radial direction. The band-shaped portion 6 is removable from the fixed portion 3 and the rotating portion 4, and in the illustrated example, a plurality of portions are connected to the rotating portion 4. Further, the band-shaped portion 6 has a knob portion 61. The knob portion 61 is provided at one end of the strip-shaped portion 6 and has a shape that is easy for the user to pick. The band-shaped portion 6 functions to prevent the rotating portion 4 from approaching the fixed portion 3.

Next, the opening of the pouch container package B1 will be described below with reference to FIGS. 10 to 19.

FIG. 4 shows the pouch container package B1 in an unopened state. In order to open the pouch container package B1 and dispense the packaged object 7, first, as shown in FIGS. 10 and 11, for example, by picking the knob portion 61, the strip-shaped portion 6 is rotated into the rotating portion 4. Remove from. In this state, the rotating portion 4 has not yet been rotated with respect to the fixed portion 3. This state is called the initial state. In the initial state, the concave portion 324 of the fixed portion 3 and the convex portion 421 of the rotating portion 4 substantially coincide with each other in the circumferential direction. Further, the tip of the cut portion 410 is separated from the flat portion 125 upward in the z direction (axial direction). In the illustrated example, the case where the circumferential position of the tip of the cut portion 410 is substantially the same as that of the concave portion 324 and the convex portion 421 will be described as an example, but this is an example and is not limited thereto.

FIG. 14 shows the relationship between the rotating portion 4 (cut portion 410) in the initial state and the flat portion 125 of the top sheet 12. FIG. (A) is a schematic view of the flat portion 125 of the top surface sheet 12 as viewed from below in the z direction (axial direction). The rotation orbit 40 is a virtual line in which the orbit drawn by the tip of the cut portion 410 due to the rotation of the rotation portion 4 is projected onto the flat portion 125 along the z direction. As will be described later, in the present embodiment, the rotating portion 4 is configured to rotate approximately 360 ° from the initial state until the flat portion 125 is completely torn, and the rotating track 40 is a substantially perfect circle. The rotation angle from the initial state to the completion of tearing of the top sheet 12 can be appropriately set, and may be, for example, 540 ° to 1080 °. In such a case, there is a margin for rotating the rotating portion 4 by 0.5 to 2 rotations from the initial state until the cut portion 410 comes into contact with the flat portion 125, and the tip of the cut portion 410 is flattened by this amount in the initial state. It can be further separated from the portion 125 in the z direction. The easy-to-tear line 120 is a linear portion provided on the flat portion 125 as described above, which is easy to tear. In FIG. 3A, the easy-to-cut line 120 is shown by a dotted line for convenience of understanding. Further, a part of the easy-to-cut line 120 overlaps with the rotary track 40, and only the dotted line indicating the easy-to-cut line 120 is shown in the portion.

Point P0 is the circumferential position of the tip of the cut portion 410 in the initial state. Since the rotating portion 4 of the present embodiment is configured to rotate clockwise with respect to the fixed portion 3 when viewed from above in the z direction, the cut portion 410 rotates counterclockwise in the figure (a). do. The easy-to-cut line 120 of the present embodiment is provided from a position separated from the point P in the circumferential direction. The distance (angle) between the point P and the end of the easy-to-cut line 120 is not particularly limited, and is, for example, about 15 ° to 60 °. The easy-to-cut line 120 has a portion that overlaps the rotary track 40 when viewed from the z direction (axial direction). The entire easy-to-cut line 120 may be configured to overlap the rotating track 40, or a part of the easy-to-cut line 120 may be configured to overlap the rotating track 40. In the illustrated example, the portion of the easy-to-cut line 120 of 1/2 or more and 3/4 or less overlaps with the rotation orbit 40. Further, the easy-to-cut line 120 has an outer guide portion 1201. The outer guide portion 1201 is provided near the end of the rotary track 40 (easy-to-cut line 120) of the split section 410 when viewed from the z direction (axial direction), and is radially outward with respect to the rotary track 40. positioned. The angle at which the easy-to-cut line 120 is provided is not limited in any way, and is provided in an angle range of, for example, 45 ° to 345 °.

FIG. 14B is a perspective view of a main part of the flat portion 125 of the top surface sheet 12 as viewed from diagonally below in the z direction (axial direction). In the initial state shown in FIG. 3B, the flat portion 125 and the cut portion 410 are described. In the initial state, the tip of the cut portion 410 is separated upward from the flat portion 125 in the z direction, and the circumferential position is at the point P0 as described above. In FIGS. (a) and (b), for convenience of understanding, an auxiliary line passing through the point P0 and parallel to the y direction and an auxiliary line perpendicular to the auxiliary line are shown. The description procedure of FIGS. 15 to 19 is the same as the description procedure of FIG.

Next, after removing the band-shaped portion 6 as shown in FIGS. 10 and 11, the rotating portion 4 is rotated with respect to the fixing portion 3. In the present embodiment, the rotating portion 4 and the cap portion 5 are integrally rotated. 11 and 15 show a state in which the cut portion 410 is rotated to the point P1 in the circumferential direction. In this state, the cut portion 410 approaches the flat portion 125 in the z direction due to the rotation of the rotating portion 4, and the tip of the cut portion 410 is in contact with the flat portion 125. In this state, the flat portion 125 is started to be torn by the cut portion 410. Therefore, in the range from the point P0 to the point P1 in the flat portion 125, the flat portion 125 is not torn. In the present embodiment, the easy-to-cut line 120 is provided from the vicinity of the point P1 where the cut portion 410 abuts on the flat portion 125.

FIG. 16 shows a state in which the rotating portion 4 is further rotated and the cut portion 410 reaches the point P2 in the circumferential direction. By rotating the rotating portion 4 from the state shown in FIG. 15 to the state shown in FIG. 16, the cut portion 410 rotates in the z direction while further moving downward in the z direction, and points from the point P1 in the circumferential direction. It is moving to P2. As a result, the flat portion 125 is partially torn by the cut portion 410. In the present embodiment, the cut portion 410 cuts the flat portion 125 along the easy-to-cut line 120 from the point P1 to the point P2.

FIG. 17 shows a state in which the rotating portion 4 is further rotated and the cut portion 410 reaches the point P3 in the circumferential direction. By rotating the rotating portion 4 from the state shown in FIG. 16 to the state shown in FIG. 17, the cut portion 410 rotates around the z direction while further moving downward in the z direction, and points from the point P2 in the circumferential direction. It is moving to P3. As a result, the flat portion 125 is further torn by the cut portion 410. In the present embodiment, the cut portion 410 cuts the flat portion 125 along the easy-to-cut line 120 from the point P2 to the point P3. The flat portion 125 is torn from the point P1 to the point P3, so that the flat portion 125 is formed with a torn piece 122. The cut piece 122 is a portion partitioned by an arc-shaped cut line 121 formed by the cut portion 410.

FIG. 18 shows a state in which the rotating portion 4 is further rotated and the cut portion 410 reaches the point P4 in the circumferential direction. By rotating the rotating portion 4 from the state shown in FIG. 17 to the state shown in FIG. 18, the cut portion 410 rotates around the z direction while further moving downward in the z direction, and points from the point P3 in the circumferential direction. It is moving to P4. As a result, the flat portion 125 is further torn by the cut portion 410, and in the illustrated example, the state of being clearly flat is released. In the present embodiment, the cut portion 410 cuts the top surface sheet 12 (flat portion 125) along the easy-to-cut line 120 from the point P3 to the point P4. As the tearing of the top sheet 12 (flat portion 125) progresses, the split piece 122 expands.

12 and 19 show a state in which the rotating portion 4 is further rotated and the cut portion 410 reaches the point P5 in the circumferential direction. The point P5 is substantially the same position as the point P0. By rotating the rotating portion 4 from the state shown in FIG. 18 to the state shown in FIG. 19, the cut portion 410 rotates around the z direction while further moving downward in the z direction, and points from the point P4 in the circumferential direction. It is moving to P5. In the present embodiment, the easy-to-cut line 120 overlaps the rotating track 40 in the range from the point P0 to the point P4, and after the point P4, the outer guiding portion 1201 located radially outward from the rotating track 40 It is provided. Therefore, although the cut portion 410 moves from the point P4 to the point P5, the cut of the top surface sheet 12 (flat portion 125) progresses along the outer guide portion 1201. As a result, the cut portion 410 behaves as being located radially inward with respect to the cut piece 122 as it moves from the point P4 to the point P5. As shown in FIG. 12, in this state, the convex portion 421 fits into the concave portion 324. As a result, further rotation of the rotating portion 4 is prevented. As described above, the concave portion 324 and the convex portion 421 regulate the rotation of the cut portion 410 starting from the point P0 to the point P5. That is, the concave portion 324 and the convex portion 421 regulate the rotation of the rotating portion 4 after the point P1 at which the cut portion 410 starts to cut the top surface sheet 12 (flat portion 125) to less than 360 °. It constitutes the rotation angle regulating means in the present invention. The specific configuration of the rotation regulating means is not limited to the configuration including the concave portion 324 and the convex portion 421. For example, the rotation regulating means may be formed by the convex portion formed in the fixed portion 3 and the concave portion formed in the rotating portion 4. Further, when one of the fixing portion 3 and the rotating portion 4 covers the other, the convex portion or the concave portion formed on the inner surface of the outer one and the concave or convex portion formed on the outer surface of the inner one. The rotation regulating means may be configured by.

By tearing the cut portion 410, an opening corresponding to the size of the cut piece 122 is formed in the portion (flat portion 125) of the top surface sheet 12 surrounded by the flange portion 31, and the container body 1 is opened. .. Then, for example, as shown in FIG. 13, the packaged object 7 can be poured out from the nozzle portion 44 by removing the cap portion 5 from the rotating portion 4. By the above steps, the opening of the pouch container package B1 is completed.

Next, the actions of the pouch container package A1 and the pouch container package B1 will be described.

According to the present embodiment, as shown in FIGS. 14 to 19, the cut portion 410 moves in the direction from the outer surface to the inner surface of the flat portion 125 of the top surface sheet 12 in the z direction (axial direction). The flat portion 125 is torn apart by rotating so as to draw a rotation trajectory 40 around the extending central axis. As a result, the flat portion 125 can be torn more reliably. For example, in a configuration in which the container body 1 is opened by breaking through the flat portion 125, the container body may not be sufficiently pierced due to the ductility of the container body, but according to the present embodiment, there is little possibility of this. Therefore, according to the pouch container package A1 and the pouch container package B1, the container body 1 can be opened more reliably.

Further, as shown in FIG. 5, the flange portion 31 of the fixing portion 3 has a flat annular shape. As a result, as shown in FIGS. 4 and 7, the portion of the flat portion 125 that overlaps the flange portion 31 when viewed from the z direction and the portion located inside the flange portion 31 can be reliably maintained flat. .. Thereby, the tearing by the cutting portion 410 can be performed more easily.

As shown in FIG. 12, by providing the rotation angle regulating means composed of the concave portion 324 of the fixing portion 3 and the convex portion 421 of the rotating portion 4, the rotating portion 4 after starting the cutting by the cutting portion 410 Rotation is restricted to less than 360 °. Therefore, as shown in FIG. 19, the range from the point P0 (point P5) to the point P1 in the flat portion 125 can be set as a region that is not cut by the cut portion 410. As a result, it is possible to prevent the torn piece 122 from being unintentionally separated from the flat portion 125, and it is possible to prevent the torn piece 122 from being mixed into the packaged object 7.

As shown in FIGS. 5 and 6, the fissure portion 410 is integrally formed with the rotating portion 4, and rotating the rotating portion 4 is the rotation of the fissure portion 410 itself. As a result, the force for rotating the rotating portion 4 is efficiently transmitted to the cut portion 410, and the flat portion 125 can be cut more reliably.

Further, as shown in FIGS. 5 and 6, the cut portion 410 is inclined so as to be located in the rotational direction toward the tip in the z direction (axial direction). As a result, as shown in FIG. 19, the tip of the cut piece 410 is arranged to enter the inside of the cut piece 122 in the radial direction, and it is possible to prevent the cut piece 122 from falling inward. This is preferable for suppressing the ejection of the packaged object 7 from being hindered by the cut pieces 122 closing the opening portion of the top sheet 12.

As shown in FIGS. 5 and 6, the first tubular portion 41 has an inclined edge 412. As a result, the first tubular portion 41 has a shape having a portion that supports the cut portion 410 from the direction opposite to the rotation direction. This is preferable to prevent the cut portion 410 from being unintentionally deformed or damaged in the tearing of the flat portion 125 by the cut portion 410.

As shown in FIGS. 9 and 14 to 18, an easy-to-cut line 120 is formed in the flat portion 125. As a result, the flat portion 125 can be cut more smoothly by the cut portion 410. In addition, it is possible to prevent the flat portion 125 from being torn at an unintended position. In the illustrated example, the easy-to-cut line 120 is not provided in the range from point P0 to point P1. As a result, the range can be set to a range that is difficult to be torn, and it is possible to prevent the torn piece 122 from being separated from the flat portion 125.

Further, the easy-to-cut line 120 is provided with an outer guide portion 1201. The outer guide portion 1201 is provided near the end of the rotary track 40 (easy-to-cut line 120), and is located radially outward with respect to the rotary track 40. As a result, the flat portion 125 can be cut radially outward from the rotary track 40, and as shown in FIG. 19, the cut portion 410 can be more reliably positioned inside the cut piece 122 in the radial direction. can. This is preferable for enhancing the fall prevention effect of the torn piece 122 by the torn portion 410.

Since the spout 2 is provided with the strip-shaped portion 6, it is possible to prevent the rotating portion 4 from being unintentionally rotated during transportation, display, etc., and to prevent the flat portion 125 from being unreasonably torn.

20 to 26 show other examples of the present invention. In these figures, the same or similar elements as those in the above embodiment are designated by the same reference numerals as those in the above embodiment.

<Spout 2 first modification>
FIG. 20 shows a first modification of the spout 2. In this example, the cut portion 410 has a shape substantially parallel to the z direction and is not tilted with respect to the z direction.

The container body 1 can be opened more reliably by this modification as well. Further, as can be understood from this modification, the specific shape such as the inclination of the cut portion 410 is not limited at all, and any shape that can cut the flat portion 125 may be used.

<Spout 2 second modification>
FIG. 21 shows a second modification of the spout 2. In this example, the cut portion 410 is inclined so as to be located in the direction opposite to the rotation direction toward the tip in the axial direction (lower end in the z-direction diagram).

The protrusion 413 is located in the rotational direction with respect to the cut 410, and protrudes downward from the inclined edge 412 in the z direction. However, the protrusion 413 has a size that does not protrude from the cut 410 in the z direction.

The container body 1 can be opened more reliably by this modification as well. Further, by providing the protrusion 413, it is possible to more reliably prevent the cut piece 122 from falling inward in the state shown in FIG. As a result, the packaged object 7 can be dispensed more smoothly.

<Spout 2 5th variant>
FIG. 24 shows a fifth modification of the spout 2. In this example, the rotating portion 4 and the cap portion 5 are integrally formed via the hinge 49. By rotating the cap portion 5 with the hinge 49 as the center of rotation, the nozzle portion 44 of the rotating portion 4 can be arbitrarily closed or opened by the cap portion 5. Such a configuration in which the rotating portion 4 and the cap portion 5 are integrally formed via the hinge 49 can be appropriately combined and adopted in other examples.

Further, in this example, the rotating portion 4 has a third tubular portion 45. The third tubular portion 45 is provided on the outside of the first tubular portion 41 so as to surround the first tubular portion 41. A first screw portion 451 is formed on the inner surface of the third tubular portion 45.

The fixed portion 3 has a fourth tubular portion 33. The fourth tubular portion 33 is provided on the outside of the second tubular portion 32 so as to surround the second tubular portion 32. A second screw portion 321 is formed on the outer surface of the second tubular portion 32.

Further, in this example, when the rotating portion 4 is lowered with respect to the fixed portion 3 by rotating the rotating portion 4 after removing the strip-shaped portion 6, the lower end of the third tubular portion 45 is flanged. The lowering of the rotating portion 4 is restricted by abutting on the portion 31 or by contacting the upper end of the fourth tubular portion 33 with the flange portion 42.

The container body 1 can be opened more reliably by this modification as well. Further, as understood from this modification, the specific configuration of the spout 2 is not limited in any way, and various configurations can be appropriately combined and adopted.

<Top sheet 12 first modification>
FIG. 25 shows a modified example of the easy-to-cut line 120 of the flat portion 125 of the top sheet 12.
In this example, the easy-to-cut line 120 has an outer guide portion 1201 and an outer guide portion 1202. The outer guiding portion 1202 is located in the direction opposite to the rotation direction with respect to the outer guiding portion 1201. Further, the outer guide portion 1202 is located radially inside with respect to the outer guide portion 1201 and is located radially outside with respect to the rotary track 40.

The container body 1 can be opened more reliably by this modification as well. Further, by providing the outer guide portion 1202, it is possible to guide the tear along the rotary track 40 to the tear along the outer guide portion 1202 and further to the tear along the outer guide portion 1201. As can be understood from this modification, the specific shape and size of the easy-to-cut line 120 are not limited at all. For example, the easy-to-cut line 120 may have a configuration (simply circular) that does not have the outer guide portions 1201, 1202 and the like and coincides with the rotation trajectory 40 when viewed from the z direction. Further, the easy-to-cut line 120 may form a double or triple circle. Further, a part or the whole of the easy-to-cut line 120 may be located radially inside the rotating track 40 when viewed from the z direction. Further, the easy-to-cut line 120 may be composed of a plurality of regions separated from each other at the start point (for example, the above-mentioned point P0) to the end point (for example, the above-mentioned point P5).

<Top sheet 12 second modification>
FIG. 26 shows a modified example of the flat portion 125 of the top sheet 12. In this example, the flat portion 125 is not provided with the easy-to-cut line 120 in the above-mentioned example.

The container body 1 can be opened more reliably by this modification as well. Further, even if the easy-to-cut line 120 is not provided, the flat portion 125 is formed by the cut portion 410 depending on the shape and material of the cut portion 410, the thickness and material of the top sheet 12, and the like. Can be torn apart.

According to the tests by the inventors, even when the flat portion 125 is not provided with the easy-to-cut line 120 having the outer guide portion 1201, the above-mentioned range from the point P4 to the point P5 The flat portion 125 is torn radially outward with respect to the rotary track 40, and the fissure portion 410 tends to be located radially inward with respect to the torn piece 122, similar to the state shown in FIG. 19 (b). Was confirmed. The reason for this is that, first, when the first tubular portion 41 moves downward in the z direction with the rotation of the rotating portion 4, the portion of the first tubular portion 41 that is located in the rotational direction with respect to the cut portion 410. However, it descends to a position where it overlaps with the flat portion 125 in the z direction. This portion is shaped to push down the flat portion 125 in the z direction prior to the cut portion 410. By this pushing down, the tear line 121 of the flat portion 125 is advanced. Then, it was observed that the progress of the tearing tends toward the tip of the cutting line 121, that is, the tangential direction of the rotating track 40.
As a result, it is considered that the cut portion 410 behaves to be located inside the cut piece 122 in the radial direction.
