[0009] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. Fig. 1 is a perspective view of a cutting device 2 for a container 1. As shown in Fig. 13(A), the container 1 of this embodiment is a beverage container made of paper and having a gable top type, approximately rectangular parallelepiped shape. The container 1 is filled with a content liquid such as milk, fruit drink, etc.

[0010] The cutting device 2 includes a device body 21 having a function of cutting the container 1, and a storage container 22 that stores the liquid content L that flows out when the container 1 is cut by the first cutting blade 54 of the device body 21. In the description of the cutting device 2 of this embodiment, the first cutting section 5 side of the device body 21 is referred to as the front, and the opposite side is referred to as the rear (see FIG. 2, etc.), and the device body 21 side in FIG. 1 is referred to as the top, and the storage container 22 side is referred to as the bottom. In this embodiment, the left and right sides of the device body 21 as viewed from the rear are referred to as the left and right sides of the cutting device 2, respectively.

[0011] The storage container 22 is formed in a substantially rectangular box shape. The storage container 22 has a socket 221 on a part of the top surface. A lid 222 is connected to a part of the main body side of the storage container 22 via a hinge part. A part or the whole of the socket 221 is configured to be openable and closable by the lid 222.

[0012] The device body 21 includes a main frame 3 that fixes the device body 21 to the storage container 22, a support portion 4 for the container 1, a first cutting portion 5, and a second cutting portion 6.

[0013] FIG. 2 is a perspective view of the main frame 3. FIG. 2 shows a state in which the first cutting section 5 and the second cutting section 6 are installed on the main frame 3. The main frame 3 has a substantially rectangular plate-shaped base section 31 and side wall sections 32 (left side wall section 32a, right side wall section 32b) extending downward from the left and right ends of the base section 31. The side wall sections 32 are formed into a substantially right-angled triangular plate shape. Each side wall section 32 has a first support rod 33 (left side support rod 33a, right side support rod 33b) arranged in the front-rear direction along the lower edge. The main frame 3 also has a second support rod 34 arranged in the left-right direction so as to connect the front ends of the left and right first support rods 33a, 33b, and a third support rod 35 arranged in the left-right direction so as to connect the rear ends of the left and right first support rods 33a, 33b. The second support rod 34 and the third support rod 35 are connected to the lower surface of the first support rod 33 .

[0014] The second support rod 34 has wall portions 341 (see also FIG. 12 ) extending downward from the front end and rear end, and mounting portions 342 extending in the left-right direction. The wall portions 341 have a long, flat plate shape extending in the left-right direction. The mounting portions 342 have a long, rectangular, flat plate shape. The lower surface of the mounting portion 342 is located above the wall portion 341. The mounting portions 342 extend to both the left and right sides beyond the left and right end portions 341a of the wall portion 341. The left and right end portions 341a are located on both the left and right sides of the side wall portions 32 with respect to the main frame 3.

[0015] The mounting portion 342 provided on the left side of the second support rod 34 has an outer wall portion 343 extending downward from the left end portion. The wall portion 343 has a female screw portion penetrating in the left-right direction. The wall portion 343 has a fixing screw member 344 that is screwed into the female screw portion from the rear left side (see also the enlarged view seen from the A direction in FIG. 2).

[0016] The first support rod 33 has an outer wall 331 extending downward from its rear end. The wall 331 has a female screw portion penetrating in the front-rear direction. The wall 331 has a fixing screw member 332 that is screwed into the female screw portion from the rear (see also the right side view of FIG. 7). The third support rod 35 has an inner wall 351 extending downward from its rear end.

[0017] The main frame 3 has its left and right mounting portions 342 mounted on the left edge 221a and right edge 221b of the socket 221 of the storage container 22, and the rear end of the first support rod 33 mounted on the rear edge 221c of the socket 221 of the storage container 22, so that the entire device body 21 can be mounted on the socket 221. At the front of the main frame 3, the wall portion 341 of the second support rod 34 is inserted into the socket 221. The wall portion 351 of the third support rod 35 is also inserted into the socket 221. Therefore, the end portion 341a of the wall portion 341 or the end portion 351a of the wall portion 351 abuts against the inner surfaces of the left and right walls of the socket 221, thereby restricting the left and right movement of the main frame 3. As shown in the enlarged view of part A, the main frame 3 is fixed in the left-right direction by clamping the second support rod 34 at the left edge 221a by screwing in the fixing screw member 344. Furthermore, the main frame 3 is fixed in the front-rear direction by clamping the third support rod 35 at the rear edge 221c by screwing in the rear fixing screw member 332.

[0018] As a result, the main frame 3 is fixed in the front-rear and left-right directions to the storage container 22. In addition, by fixing the main frame 3 to the receiving port 221 of the storage container 22, the base portion 31 is fixed at a preset angle by an edge portion corresponding to the hypotenuse of the side wall portion 32 having a right-angled triangular shape.

[0019] The main frame 3 has a first rail 36 arranged in the left-right direction (first direction) and a second rail 37 arranged in the approximately front-rear direction (second direction). The first rails 36 are provided in a pair on the front and rear. The second rails 37 are provided in a pair on the left and right.

[0020] The first rail 36 has an upper surface guide portion 361. The first rail 36 also has a side surface guide portion 362 on the inner surface sides facing each other. The upper surface guide portion 361 and the side surface guide portion 362 are each a concave groove portion formed in the left-right direction. The support portion 4 is configured to be movable in the left-right direction by having the roller 416a (see FIG. 3(B)) guided by the upper surface guide portion 361 and the roller 416b (see FIG. 3(B)) guided by the side surface guide portion 362. The support portion 4 is also configured to be movable in the left-right direction by having the roller 416a guided by the upper surface guide portion 361 so that the movement in the front-rear direction is restricted, and the roller 416b is guided by the side surface guide portion 362 so that the movement in the up-down direction is restricted.

[0021] In this manner, the device body 21 constitutes a first moving mechanism 211 including the first rail 36 and the support part 4. The first moving mechanism 211 is configured to enable the first cutting blade 54 and the container 1 accommodated in the support part 4 to move relatively toward or away from each other.

[0022] The second rail 37 has an upper surface guide portion 371 on the upper surface side. The second rail 37 also has a side surface guide portion 372 on the inner surface side facing each other. The upper surface guide portion 371 and the side surface guide portion 372 are recessed groove portions formed in the left-right direction. The second cutting portion 6 is configured to be movable in approximately the front-rear direction by having the roller 612a (see FIG. 6(B)) guided by the upper surface guide portion 371 and the roller 612b (see FIG. 6(B)) guided by the side surface guide portion 372. The second cutting portion 6 is also restricted in its movement in the approximately left-right direction perpendicular to the second rail 37 by having the roller 612a guided by the upper surface guide portion 371, and restricted in its movement in the up-down direction (the plate thickness direction of the base portion 31) by having the roller 612b guided by the side surface guide portion 372.

[0023] In this way, the device body 21 configures a second movement mechanism 212 by the second rail 37 and the second cutting unit 6. The second movement mechanism 212 configures the second cutting blade 63 and the container 1 accommodated in the support unit 4 to be movable relatively in a direction toward or away from each other. The second cutting blade 63 is also configured to be movable relatively in a direction toward or away from the first cutting blade 54 (first movement mechanism 211).

[0024] The main frame 3 has a guide plate 38 on the forward side of the first rail 36 where the first cutting section 5 is provided. The guide plate 38 is formed at approximately the same height (e.g., more than half the height) as the container 1 housed in the support section 4. The guide plate 38 has two flat portions 381, 382 that are approximately parallel to the moving direction of the support section 4 (in other words, the moving direction of the container 1), and an inclined portion 383 that connects the flat portion 381 and the flat portion 382. The flat portion 382 located on the first cutting section 5 side is located closer to the support section 4 than the flat portion 381.

[0025] Fig. 3(A) is a perspective view of the support part 4 as viewed from above. Fig. 3(B) is a perspective view of the support part 4 as viewed from below. The support part 4 has a container storage part 41 that supports the position and posture of the container 1, and an operation part 42 that operates the position of the support part 4 relative to the first rail 36.

[0026] The container housing part 41 has a rectangular flat bottom plate 411, a plate-shaped first side wall 412, and a second side wall 413. The bottom plate 411 and the first side wall 412 are connected at a substantially right angle. The first side wall 412 has a plate-shaped protective part 412a at its front end, which is extended toward the operation part 42 side, which is the opposite side to the container housing part 41. The protective part 412a has a function of protecting the arm of an operator holding the grip part 422 from the first cutting blade 54 when the support part 4 is moved to cut the container 1 with the first cutting blade 54. The bottom plate 411 and the second side wall 413 are connected at a substantially right angle with the front side spaced apart via a connecting member 415 provided at the rear of the support part 4. Therefore, a slit 413a (gap) is formed between the bottom plate 411 and the second side wall 413 in the front-rear direction from the front end part 411a of the bottom plate 411 to the position of the connecting member 415. The slit 413a is a through-hole that passes through the container storage portion 41 from the inside to the outside in the left-right direction of the support portion 4.

[0027] The container accommodating section 41 also has a third side wall 414 at the rear, adjacent to the bottom plate 411, the first side wall 412, and the second side wall 413. The third side wall 414 has an inner wall 414a that is symmetrical and has a generally obtuse V-shape in a plan view of the container accommodating section 41 seen from the normal direction of the bottom plate 411. A slit-like recessed groove 414b extending toward the rear of the support section 4 is formed in an inside corner of the inner wall 414a. The third side wall 414 also has a slit 414c (gap) that separates the second side wall 413 side of the inner wall 414a and the recessed groove 414b from the bottom plate 411 (enlarged view of part B).

[0028] Since the support part 4 has the slits 413a and 414c, the second cutting blade 63 of the second cutting part 6 can be moved relative to the support part 4 (in other words, relative to the container 1) while being inserted inside the container storage part 41. In addition, the third side wall 414 can be fixed at any front-rear position along a long hole 411b provided in the bottom plate 411 in the front-rear direction. Therefore, the container storage part 41 can change the length of the storage space according to the length of the container.

[0029] 3(B), a plurality of rollers 416a, 416b functioning as guided portions of the first rail 36 are provided on the lower surface of the container storage section 41. Each of the rollers 416a, 416b includes a roller 416a having a rotation axis in the thickness direction of the bottom plate 411, and a roller 416b that is parallel to the bottom plate 411 and has a rotation axis in the approximately front-rear direction of the support section 4.

[0030] Furthermore, the container storage part 41 has a cylindrical protrusion 417 on the lower surface. The protrusion 417 comes into contact with the restricting protrusion 311 or the restricting protrusion 312 provided between the first rails 36 of the main frame 3 to restrict the movement of the support part 4 in the left-right direction along the first rails 36 and set the movement range of the support part 4.

[0031] The operation unit 42 is provided on the first side wall 412 side corresponding to the right side surface of the container storage unit 41. The operation unit 42 has a gripping unit 422 connected via an arm 421 extended from the outer surface of the container storage unit 41, a lever 423 rotatably connected to one of the arms 421 and disposed substantially parallel to the gripping unit 422 below, and a rod-shaped engaging unit 424 connected to the lever 423 via a rotating shaft 423a and rotating in conjunction with the lever 423. The engaging unit 424 is configured to be engaged with and disengaged from any of a plurality of engaged units 313 (see FIG. 2, etc.) provided in the left-right direction on the base unit 31 according to the position of the support unit 4 on the first rail 36. In a state in which the engaging unit 424 and the engaged unit 313 are engaged with each other (for example, a state in which the engaging unit 424 is in a position indicated by a solid line in FIG. 7), the movement of the support unit 4 is restricted. The operation for releasing the engagement state of engagement portion 424 is performed, for example, by the user gripping lever 423 together with grip portion 422 and rotating them upward.

[0032] FIG. 4(A) is a perspective view of the first cutting section 5 as viewed from one side. FIG. 4(B) is a perspective view of the first cutting section 5 as viewed from the other side. The first cutting section 5 has a long rectangular plate-shaped main body 51, a plate-shaped first support member 52 and a plate-shaped second support member 53 fixed to the first surface side of the main body 51, and a first cutting blade 54. As shown in the enlarged view of part C, the first support member 52 has a step portion 521 in which the tip of a part of a linear edge portion is cut out in an L-shape in cross section (or plan view). The first support member 52 is fixed to the main body 51 together with the second support member 53 with the step portion 521 side facing the second support member 53. Therefore, a concave groove portion 55 is formed between the first support member 52 and the second support member 53. The groove portion 55 is provided to be approximately the same thickness as the first cutting blade 54 or slightly wider.

[0033] The first cutting blade 54 is a straight blade. The base side of the first cutting blade 54 is fixed to the main body 51 with the ridge 541 side housed in the groove 55. Therefore, the first cutting blade 54 is supported in the blade thickness direction as well as in the longitudinal direction by the first support member 52 and the second support member 53 at the ridge 541, so that the overall posture including the cutting edge 542 side is stably supported when the container 1 is cut.

[0034] 2, the first cutting part 5 is fixed to the base part 31 with the blade tip 543 inclined. The first cutting part 5 is detachable from the base part 31. The first cutting blade 54 of this embodiment is disposed so as to be positioned from right to left of the device body 21 from the base of the blade toward the cutting tip 542. That is, the blade tip 543 of the first cutting blade 54 is inclined so as to abut (cut) against (from below) the container 1 toward above the container 1 approaching the first cutting blade 54.

[0035] FIG. 5 is a perspective view of the cover member 7 as viewed from below. The cover member 7 is formed in a box shape that is approximately a rectangular parallelepiped as a whole. The cover member 7 is formed long in the front-rear direction, with the left side, front side, rear side, and upper side surrounded by flat wall portions 71a to 71d. The left wall portion 71a is formed to have a shorter vertical width than the front and rear walls 71b and 71c. In addition, the front and rear walls 71b and the front and rear walls 71c have their tips bent at approximately right angles to opposite sides to each other, and have flange-shaped connecting portions 71b1 and 71c1 for connecting to the base portion 31. Each connecting portion 71b1 and 71c1 has an elongated positioning hole 711 and a screw hole 712 through which a fixing screw is inserted. The front wall portion 71b has a cutout portion 71b2 cut into an elongated rectangular shape at the lower left corner.

[0036] A part of an inner surface 71d1 of the upper wall portion 71d protrudes downward via an inclined portion 71d2. The inclined portion 71d2 functions as a guide portion when the container 1 supported by the support portion 4 is moved from the outside to the inside of the cover member 7. The container 1 accommodated in the cover member 7 is stably supported by the inner surface 71d1 of the cover member 7 and the container accommodation portion 41, with the movement in the up and down direction being restricted.

[0037] The cover member 7 also has a container guide portion 72 that guides a surface of a portion of the container 1 that has been cut into the inside. The container guide portion 72 is formed in a flat plate shape that is a substantially right-angled triangle, and is provided so as to protrude from the inner surface of the left wall portion 71a. The container guide portion 72 has an edge 721 on the container 1 side in a state in which the cover member 7 is attached in FIG. 1, which is substantially parallel to the left-right direction. The container guide portion 72 also has an edge 722 on the opposite side to the container 1 that is inclined with respect to the wall portion 71a.

[0038] Positioning protrusions 317 provided on the base portion 31 are inserted into the positioning holes 711 of the cover member 7. The cover member 7 is fixed to the base portion 31 by screwing the screw members 73 into the screw holes 318 through the screw holes 712.

[0039] Fig. 6(A) is a perspective view of the second cutting unit 6 as viewed from one side. Fig. 6(B) is a perspective view of the second cutting unit 6 as viewed from the other side. The second cutting unit 6 has a thick plate-like base portion 61, a cylindrical rod-like gripping portion 62 arranged approximately parallel to the base portion 61, and a second cutting blade 63 detachably fixed to the upper surface side of the base portion 61. The gripping portion 62 is connected to the base portion 61 at a distance above the base portion 61 via a base portion 64 extending upward.

[0040] The second cutting blade 63 is a straight blade. The second cutting blade 63 is supported and fixed by being sandwiched from above between a flat fixing member 65 and the bottom of the countersunk portion 611 while being housed in the countersunk portion 611 formed on the upper surface of the base portion 61. The second cutting blade 63 is positioned with the cutting edge 633 inclined so that the cutting edge 631 side is located further forward than the base portion 632 side (see also FIG. 8, etc.).

[0041] 6(B), a plurality of rollers 612a, 612b functioning as guided portions of the second rail 37 are provided on the underside of the second cutting portion 6. Each of the rollers 612a, 612b includes a roller 612a having a rotation axis in the thickness direction of the base portion 61, and a roller 612b that is parallel to the base portion 61 and has a rotation axis in the approximately left-right direction of the base portion 61.

[0042] The base portion 61 has a cylindrical protrusion 613 on the lower surface. The protrusion 613 comes into contact with a restricting protrusion 314 or a restricting protrusion 315 (see FIG. 12 ) provided between the second rails 37 of the main frame 3 to restrict the movement of the second cutting unit 6 in the approximately front-rear direction along the second rails 37 and set the movement range of the second cutting unit 6.

[0043] Next, the operation of the cutting device 2 will be described. Figures 8 to 11 are views seen from the normal direction of the base portion 31 of the main frame 3, and the illustration of the cover member 7 is omitted (however, for the sake of explanation, the position of the container guide portion 72 is shown). Also, the container 1 is illustrated in cross section.

[0044] First, when arranging the container 1 in the container housing part 41, as shown in FIG. 8, the first moving mechanism 211 moves the support part 4 to a position separated from the first cutting part 5. The support part 4 arranges the first surface 11 (bottom surface) of the container 1 on the lower side and supports the container 1 in an inclined state in the container housing part 41 (see also the side view of the container housing part 41 in FIG. 7). The container 1 is arranged with the first surface 11 side above the receiving port 221 of the storage container 22. The device main body 21 is fixed to the receiving port 221, so that the first moving mechanism 211 and the second moving mechanism 212 are fixed to the storage container 22. When the user holds the grip part 422 and the lever 423, etc., and pulls the lever 423 upward, the engagement of the engaging part 424 with the engaged part 313 is released, and the support part 4 becomes movable along the first rail 36.

[0045] When the support part 4 moves towards the first cutting blade 54, the first surface 11 of the container 1 is guided by the guide plate 38 along the inclined portion 383 and then the flat portion 382, ​​and is urged towards the rear side of the support part 4. As a result, the container 1 is pressed against the third side wall 414 located at the rear of the container storage part 41 and stably supported in the front-to-rear direction, while when the bottom part (first surface 11) of the container 1 is at the position of the flat portion 381, i.e., the position when the container 1 is inserted or removed, the urging force against the container 1 is released, so that the container 1 can be easily inserted or removed.

[0046] As shown in FIG. 9, the first moving mechanism 211 moves the container 1 supported by the support part 4 toward the first cutting blade 54 so that the first cutting blade 54 enters from a surface adjacent to the first surface 11 (the second surface 12 on the left side of the container 1 in this embodiment). Therefore, the container 1 moves while being cut by the first cutting blade 54. In addition, since the first cutting blade 54 is inclined, it enters and cuts the container 1 so as to abut against the container 1 from below toward above. The first surface 11 side of the container 1 is guided in a direction away from the container 1 by the outer inclined surface 522 of the first support member 52 in order from the cut portion. Therefore, the container 1 moves toward the second cutting part 6 while the cut opening widens.

[0047] Fig. 10 is an enlarged cross-sectional view taken along line IX-IX in Fig. 9. When the container 1 contains liquid content L, the liquid content L flows out when a part of the container 1 is cut. At this time, the first surface 11 is lifted by the edge 722, so that the liquid content L can easily flow out. In the cutting device 2 of this embodiment, the first cutting blade 54 is provided substantially above the opening 316 of the base part 31, so that the cutting position of the container 1 is located substantially above the opening 316. Therefore, the liquid content L that flows out when the container 1 is cut is discharged into the storage container 22 through the opening 316 and the receiving port 221.

[0048] As shown in FIG. 11, when the container 1 moves further together with the support part 4, the first cutting blade 54 cuts the second surface 12 to the fourth surface 14 (three adjacent side surfaces) in the vicinity of the first surface 11 of the container 1 supported by the support part 4 and adjacent to the first surface 11. The portion of the first surface 11 side where the second surface 12 to the fourth surface 14 are cut is guided by the edge 722 and the inclined tip part 634 of the second cutting blade 63 and is urged toward the opposite side to the container housing part 41. The portion of the first surface 11 side is opened while remaining connected to the fifth surface 15. In addition, since the cut end 121 of the second surface 12 is fixed to the third side wall 414 side of the container housing part 41 by the edge 721, the cut end 131 of the third surface 13 adjacent to the second surface 12 is also urged toward the third side wall 414 side, as shown in the enlarged view of part E in FIG. 11. A perspective view of the container 1 cut by the first cutting blade 54 is shown in FIG. 12.

[0049] FIG. 12 is a perspective view of the device body 21 showing a state in which the container 1 has been cut by the first cutting unit 5. After the container 1 has been cut by the first cutting blade 54, the user operates the second moving mechanism 212 to pull it toward the front side of the device body 21, for example by gripping the gripping portion 62 of the second moving mechanism 212. The second moving mechanism 212 moves the second cutting blade 63 so as to approach the container 1 while cutting the container 1. In this embodiment, the second moving mechanism 212 causes the second cutting blade 63 to enter from the cutting end 121 of the surface (here, the second surface 12) adjacent to the first surface 11, and cuts the second surface 12 while moving it in the rear direction, which is the direction away from the first surface 11. The position of the second cutting unit 6-1(6) after cutting the second surface 12 is indicated by a dotted line in FIG. 12.

[0050] Thereafter, the user operates the gripping portion 62 to return the second cutting portion 6 to the standby position on the front side, and further operates the gripping portion 422 to return the support portion 4 to the standby position on the right side (the state in FIG. 8 ). When the support portion 4 is in the standby position, the operator can remove the cut container 1 from the container storage portion 41.

[0051] 13(B) is a perspective view of the container 1 cut by the first cutting section 5 and the second cutting section 6. The container 1 has been cut by the first cutting section 5 at the second surface 12 to the fourth surface 14 (three adjacent side surfaces) near the first surface 11 and adjacent to the first surface 11. In the cut container 1, the first surface 11 is adjacent to the first surface 11, the second surface 12, and the fourth surface 14, and maintains a state in which the boundary edges of the first surface 11 and the fifth surface 15 opposite the third surface 13 are connected.

[0052] In addition, a cut portion 122 is formed on the second surface 12 of the container 1 by the second cutting blade 63. In addition, a cut portion 162 is formed on the inclined portion 161 of the gable portion 16 adjacent to the second surface 12 of the container 1 by the second cutting blade 63, which is continuous with the cut portion 122. When the cut container 1 is operated by an operator to widen the opposing edges of the cut portion 122, the joined opposing inclined portions 161 of the gable portion 16 are broken or peeled off and separated. When the opposing edges of the cut portion 122 are further widened, the first surface 11 corresponding to the bottom surface, the second surface 12 to the fifth surface 15 corresponding to the side surfaces, and the gable portion 16 are unfolded, and the entire container 1 can be deformed into a flat shape.

[0053] As described above, in this embodiment, the cutting device 2 is provided with the support part 4 supporting the rectangular parallelepiped container 1, the first cutting blade 54 cutting the second surface 12 to the fourth surface 14 in the vicinity of the first surface 11 of the container 1 supported by the support part 4 and adjacent to the first surface 11, and the second cutting blade 63 cutting the surface adjacent to the first surface 11 in a direction away from the first surface 11. In this cutting device 2, the first cutting blade 54 and the container 1, and the second cutting blade 63 and the container 1 are configured to be movable relatively in the direction of approaching or moving away from each other. Therefore, the container 1 is cut at multiple points by the first cutting blade 54 and the second cutting blade 63 provided in advance in a stable state supported by the support part 4. Therefore, the cutting device 2 of this embodiment can improve the workability compared to the conventional technology. In addition, when the content liquid L is contained in the container 1, the cutting device 2 of this embodiment can prevent leakage of the liquid to the surroundings by using the device body 21 together with the storage container 22.

[0054] Although several embodiments of the present disclosure have been described above, these embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and modifications are within the scope of the invention and its equivalents as described in the claims, as well as the scope and spirit of the invention.

[0055] For example, the storage container 22 may be provided with a flow path for draining liquid at a position (for example, a position near the bottom surface of the storage container 22) other than the receiving port 221. This allows the content liquid L that has flowed from the container 1 into the storage container 22 to flow to another position.

[0056] The container 1 may also be in another shape, such as a brick shape, or in another substantially rectangular parallelepiped shape. Furthermore, the container 1 may also be in another three-dimensional shape, such as a cylindrical shape or a triangular prism shape.

[0057] In addition, the first moving mechanism 211, which moves the first cutting blade 54 and the container 1 contained in the support part 4 in a direction toward or away from each other, may be configured to move the first cutting blade 54 or a blade equivalent to the first cutting blade 54 toward or away from the support part 4, although not shown in the figure.

[0058] In addition, the second moving mechanism 212, which moves the second cutting blade 63 and the container 1 contained in the support part 4 in a relative direction toward or away from each other, may be configured to move the support part 4 toward or away from the second cutting blade 63 or a blade equivalent to the second cutting blade 63, although not shown in the figure.
