Mode for Carrying Out the Invention

[0010] Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a decoration body forming toy set 1. The decoration body forming toy set 1 includes an extruder 2 and a pedestal 7. The user can squeeze the cream-like materials 30 (30A to 30D) filled in the respective containers 3 (3A to 3D) of the extruder 2 from the rear (upper side in FIG. 1) to the front (lower side in FIG. 1) of the container 3, so that the cream-like material 30 can be extruded (pushed out) from the opening 531 of the tip base 5. The extruded cream-like material 30 can be applied to the formation surface 71 of the pedestal 7 to create a decoration body toy imitating a Western confectionery or the like decorated with fresh cream. The pedestal 7 shown in FIG. 1 is formed in a short cylindrical shape.

[0011] Hereinafter, a decoration body forming toy set 1 in which a cream resin is used as the cream-like material 30 and the extruder 2 is mainly applied for play as a decoration body forming toy will be described. Note that the extruder 2 of the present embodiment may use a cream-like material such as whipped cream used for general food instead of the cream resin. In this case, the extruder 2 can be used for plating foods such as sponge cake instead of the pedestal 7.

[0012] Figure 2 is an exploded perspective view of the squeezing tool 2. In the following description of the squeezing tool 2, the side of the container 3 is the rear and the side of the base 5 is the front. The squeezing tool 2 includes a container 3, an intermediate member 4, a base 5, and a cap 6. A bag body 31 containing a cream-like substance 30 is provided in most of the rear part of the container 3. The bag body 31 is formed by overlapping two flexible sheet members 311 such as polyvinyl chloride resin and bonding them by heat pressing or the like. The rear end portion of the bag body 31 is closed by bonding the two overlapping sheet members 311 by heat pressing or the like (details are not shown).

[0013] The container 3 is connected to a plurality of supply ports 44 of the intermediate member 4. The squeezing tool 2 of this embodiment uses four containers 3A to 3D each containing different types of cream-like substances 30A to 30D (see FIG. 1) in the bag body 31. The cream-like substance 30 filled in the bag body 31 imitates whipped cream and can contain, for example, synthetic paste, acrylic resin, cellulose, stabilizer, preservative, etc. Therefore, the cream-like substance 30 solidifies when it comes into contact with air and dries. The cream-like substances 30A to 30D of this embodiment are colored in different colors by adding coloring agents.

[0014] Also, the bag bodies 31 of the respective containers 3A to 3D are tied and bundled together by detachable binding bands 33 (see FIG. 1). By shifting the binding position forward according to the decrease in the cream-like substances 30A to 30D, it is possible to reduce the backward flow (backflow) of the cream-like substances 30A to 30D when using the squeezing tool 2.

[0015] In FIG. 2, the connecting portion 32 has a rear stage portion 321 with a large outer diameter and a front stage portion 322 with a small outer diameter, and is formed in a substantially cylindrical shape as a whole. A flange portion 321a is formed along the circumferential direction at the rear end edge of the rear stage portion 321. Also, on the outer peripheral side surface of the rear stage portion 321, a plurality of protruding diameter portions 321b having a diameter larger than that of the outer peripheral side surface are formed along the circumferential direction. The protruding diameter portions 321b are arranged in a plurality in the front-rear direction.

[0016] The bag body 31 has an opening 312 at its front end. This opening 312 is connected to the connecting part 32. The opening 312 is formed by adhering the side edges of the two sheet members 311 except for the front end. Also, in the vicinity of the opening 312, the side edges are adhered so that the inner edge of the opening 312 is in close contact with the rear stage part 321 of the connecting part 32. Since the protruding diameter part 321b provided on the rear stage part 321 is in close contact with the inside of the opening 312, it is possible to prevent the cream-like substance 30 from leaking from the gap between the outer peripheral side surface of the rear stage part 321 and the opening 312.

[0017] On the outer peripheral side surface of the front stage part 322, a male screw part 322a is formed. Near the end of the groove part 322b of the male screw part 322a, a flat convex-shaped locking projection 322c is formed. The locking projection 322c is formed lower than the thread of the male screw part 322a.

[0018] The intermediate member 4 shown in FIGS. 3(a) and 3(b) merges the cream-like substance 30 supplied from the supply port part 44 to which the container 3 is connected at the front merging part 418 and causes it to flow toward the cap 5 side. The intermediate member 4 has a main body part 41, a switching member 42 arranged behind the main body part 41, and a support member 43 that supports the switching member 42 in a housed state with respect to the main body part 41.

[0019] As shown in FIG. 4(a), the main body part 41 is formed in a circular thick plate shape. On the rear surface part 41a of the main body part 41, a recess 411 capable of housing the switching member 42 in a predetermined orientation is provided. A plurality of recesses 411 are arranged around the axis P at the center of the main body part 41. In this embodiment, four recesses 411 are provided.

[0020] The recess 411 is formed in a substantially circular groove shape. On a part of the inner peripheral surface of the recess 411, a bulging part 411a and a bulging part 411b that bulge outward in the radial direction of the recess 411 are provided. The bulging part 411a is arranged on the axis P side of the main body part 41. The two bulging parts 411b provided are arranged on the side farther from the axis P of the main body part 41 than the bulging part 411a. Each of the bulging parts 411a and the bulging part 411b is arranged at substantially equal intervals (substantially equal angles around the axis P of the recess 411) around the outer periphery of the recess 411.

[0021] The bottom surface portion of the recess 411 is formed in a flat shape. From the bottom surface portion of the recess 411, a C-shaped inner wall portion 412 is provided. The inner wall portion 412 and the inner peripheral surface of the recess 411 are arranged to be spaced apart. Also, the inner wall portion 412 is formed lower than the rear surface portion 41a of the main body portion 41. The inner wall portion 412 has a notch portion 412a that is partially cut out on the side of the bulging portion 411a. An opening 413 that communicates with the direct current portion 417, which is a flow path for the cream-like substance 30, is provided on the bottom surface portion of the recess 411 on the side of the bulging portion 411a (on the side of the axis P) rather than the notch portion 412a (see Fig. 4(b)). The opening 413 is arranged to include a part of the bulging portion 411a.

[0022] Also, on the bottom surface portion of the recess 411, on the side of the bulging portion 411b rather than the inner wall portion 412, an engaging groove 414 in the shape of a long concave groove along the direction of the inner wall portion 412 is provided (see also Fig. 4(b)). The engaging groove 414 is provided corresponding to each bulging portion 411b.

[0023] The outer peripheral portion 415 of the main body portion 41 is radially outside with respect to the axis P rather than the rear surface portion 41a and has an annular contact portion 415a at a position behind the rear surface portion 41a. The contact portion 415a is formed in a flat surface shape. Also, at a position further to the rear side than the contact portion 415a, a plurality of engaging protrusions 415c are provided at intervals. The engaging protrusions 415c are provided so as to protrude inward from an outer peripheral wall portion 415b provided around the outer periphery of the contact portion 415a. Also, the engaging protrusions 415c are provided at four locations at substantially equal intervals (substantially equal angles around the axis P) in the circumferential direction around the axis P.

[0024] As shown in Fig. 3(b), a conduit portion 416 is provided on the front side of the main body portion 41 on the axis P. Inside the hollow cylindrical interior of the conduit portion 416, a direct current portion 417, which is a plurality of flow paths formed by being divided into a cross shape by an inner wall, is formed. Therefore, the cross section of each direct current portion 417 is formed in a substantially fan shape with a right inner angle. On the opening portion 413 side of the direct current portion 417, a large diameter portion 417a connected to the opening portion 413 and a reduced width portion 417b with a part of the inner peripheral surface inclined forward from the large diameter portion 417a are provided (see also Figs. 7 to 10). A small diameter portion 417c having substantially the same cross-sectional shape extending in the front-rear direction (up-down in Fig. 3(b)) is provided between the reduced width portion 417b and the opening portion 417d (see also Figs. 7 to 10). Also, the opening portions 417d on the front end side of each direct current portion 417 have opening surfaces on the same plane. Therefore, a confluence portion 418 where each direct current portion 417, which is a flow path, converges is formed at the front end of the conduit portion 416.

[0025] On the outer peripheral side surface of the conduit portion 416 on the opening portion 417d side, a male screw portion 416a that can be screwed with the female screw portion 541 of the base 5 is provided.

[0026] The switching member 42 shown in Figs. 5(a) and 5(b) is formed in a short, substantially cylindrical shape with both ends open. On a part of the outer peripheral surface of the side wall portion 421, a positioning projection 423 protruding radially outward with respect to the axis Q is provided. Inside the positioning projection 423, a bulging space portion 422 bulging radially outward with respect to the axis Q of the switching member 42 is provided so that a part of the inner surface of the side wall portion 421 is interrupted. The cross-sectional shape of the positioning projection 423 including the bulging space portion 422 is formed in substantially the same shape in the axis Q direction.

[0027] In addition, on the outer peripheral surface of the side wall portion 421, a positioning projection 424 having substantially the same outer shape as the positioning projection 423 is provided. In the present embodiment, one positioning projection 423 is provided, and two positioning projections 424 are provided. On the rear end side of the inner peripheral surface of the side wall portion 421 (the upper end side in FIG. 5(a)), an internal thread portion 421a is provided. The internal thread portion 421a of the present embodiment has a thread formed by a plurality of intermittently provided protrusions. Each protrusion of the intermittently provided thread is arranged so as not to overlap in the axial direction Q. Therefore, the switching member 42 can be formed by a split mold that moves in the axial direction Q including the internal thread portion 421a and can be manufactured by a simple method.

[0028] At the upper end portion of the side wall portion 421, a flange portion 425 wider than the plate thickness of the side wall portion 421 is provided. The flange portion 425 is formed in an annular shape so as to extend radially outward with respect to the axis Q from the rear end portion of the side wall portion 421. Further, the flange portion 425 is arranged so as to cover the bulging space portion 422 from the rear end side. Therefore, the bulging space portion 422 has an opening portion 422a that opens in the axial direction Q (vertical direction) and an opening portion 422b that opens on the front side. By arranging the opening portion 422a on the side of the notch portion 412a, the inlet (opening portion 413) of the flow path on the confluence portion 418 side can be opened (see FIG. 7).

[0029] On the upper surface of the flange portion 425 corresponding to the position of the bulging space portion 422 (positioning projection 423), an equilateral triangular marker 425a is provided. By providing the marker 425a, the position of the bulging space portion 422 (positioning projection 423), which is a part of the flow path, can be easily grasped when the switching member 42 is viewed from above.

[0030] Also, as shown in FIG. 5(b), on a part of the lower end of the side wall portion 421, closing projections 421b are provided at two positions corresponding to the positioning projections 424. The closing projections 421b have substantially the same plate thickness as the side wall portion 421 and are provided with substantially the same width as the positioning projections 424 in the circumferential direction of the axis Q. One side surface of the closing projection 421b is continuous with the inner peripheral surface of the side wall portion 421.

[0031] The support member 43 shown in FIGS. 6(a) and 6(b) is formed in a substantially disc shape that has a smaller diameter than the outer peripheral wall portion 415b of the main body portion 41 (see FIG. 4(a)) and a larger diameter than the outer diameter of the rear surface portion 41a. Therefore, the support member 43 can be placed in a state of abutting against the abutting portion 415a of the main body portion 41 (see also FIG. 7).

[0032] A plurality of circular openings 431 are provided in the support member 43 around the axis P. The inner diameter of the opening 431 is provided to be substantially the same diameter as the side wall portion 421 of the switching member 42. Also, around the outer periphery of the opening 431, a cylindrical wall portion 432 stands upright from the rear surface portion 43a toward the rear (upward in FIG. 6(a)). The inner diameter of the cylindrical wall portion 432 is provided to be larger than the opening diameter of the opening 431. A notch portion 432a that is notched in a U shape is formed in a part of the end portion of the cylindrical wall portion 432.

[0033] On the outer peripheral edge portion of the support member 43, an inner wall portion 433 and an outer wall portion 434 that is located farther from the axis P than the inner wall portion 433 are alternately in contact and arranged in the circumferential direction. The inner wall portion 433 and the outer wall portion 434 stand upright on the rear surface portion 43a side. The outer peripheral surface of the inner wall portion 433 is provided so as to be located on the axis P side with respect to the inner edge of each engaging protrusion 415c shown in FIG. 4(a). Also, the outer peripheral surface of the outer wall portion 434 is provided so as to be located on the axis P side with respect to the outer peripheral wall portion 415b shown in FIG. 4(a) (see also FIG. 3(a)).

[0034] An engaged protrusion 433a arranged along the circumferential direction of the axis P is provided on a part of the outer peripheral surface of the inner wall portion 433. The tip portion of the engaged protrusion 433a is located substantially on the same diameter with respect to the outer peripheral surface of the outer wall portion 434 and the axis P. Also, the engaged protrusion 433a is arranged on the counterclockwise direction side of the inner wall portion 433 when viewed from the rear side (rear surface portion 43a side). The front surface portion 43b of the support member 43 is formed in a flat surface shape as shown in FIG. 6(b).

[0035] Returning to FIG. 2, the base 5 has a rear stage portion 51 with a large outer diameter, a middle stage portion 52 with a smaller outer diameter than the rear stage portion 51, and a front stage portion 53 with a smaller outer diameter than the middle stage portion 52. The whole of the base 5 is formed in a substantially cylindrical shape. A flange portion 511 is provided at the rear end edge of the rear stage portion 51. Further, a plurality of rib portions 512 are formed in the front-rear direction (vertical direction in FIG. 2) on the outer peripheral side surface of the rear stage portion 51. A display plate 513 extending rearward is provided from a part of the side surface of the rear stage portion 51. On the plate surface on the outer peripheral side (right side in FIG. 2) of the display plate 513, the shape type of the opening portion 531 of the base 5 can be displayed by characters, figures, etc. The shape type includes the shape and size of the opening portion 531. Further, a male screw portion 521 is provided on the outer peripheral side surface of the middle stage portion 52.

[0036] The outer diameter of the front stage portion 53 is formed so as to gradually decrease in diameter toward the front. An opening portion 531 is formed at the front end of the front stage portion 53. The opening portion 531 can be an opening shape generally used in a whipping cream squeezing tool. In this embodiment, a star 8-cut type is used. Therefore, the opening portion 531 has eight pointed plates 531a annularly arranged such that the acute-angle apex faces the central side of the opening portion 531 in a plan view (details not shown) when viewed from below. A notch portion 531b is formed between the pointed plates 531a.

[0037] Further, as mainly shown in FIG. 7, the base 5 has a rear inner wall portion 54 with a large inner diameter and a front inner wall portion 55 with a smaller inner diameter than the rear inner wall portion 54. A female screw portion 541 that engages with the male screw portion 416a of the conduit portion 416 is provided on the rear inner wall portion 54. The inner diameter of the front inner wall portion 55 gradually decreases in a mortar shape toward the opening portion 531. A stepped rear abutting portion 56 having a flat surface facing rearward is formed at the boundary between the rear inner wall portion 54 and the front inner wall portion 55.

[0038] The cap 6 shown in FIG. 2 is formed in a cylindrical shape having a bottom at the front end side. A flange portion 611 is provided at the rear end edge of the cap 6. A plurality of vertical ribs 612 are provided on the outer peripheral side surface 61 of the cap 6. Further, a female screw portion 621 that can engage with the male screw portion 521 of the base 5 is provided on the rear end side of the inner peripheral wall 62 of the cap 6.

[0039] Here, a method for assembling the squeezing member 2 will be described. Regarding the intermediate member 4, first, the switching member 42 shown in FIG. 5(a) etc. is disposed in the annular groove portion between the inner peripheral surface of the recess 411 provided on the rear surface portion 41a of the main body portion 41 shown in FIG. 4(a) and the inner wall portion 412. The switching member 42 is accommodated in combination with either the positioning protrusion 423 or the positioning protrusion 424 with respect to the bulging portion 411a and the bulging portion 411b, and is disposed from the rear with respect to the recess 411. That is, the positioning protrusion 423 having the bulging space portion 422 inside can be disposed at any of the three bulging portions 411a or the bulging portion 411b.

[0040] When the positioning protrusion 423 is disposed at the bulging portion 411a, the bulging space portion 422 formed inside the positioning protrusion 423 is disposed adjacent to the notch 412a of the inner wall portion 412 (see the switching member 42C in FIG. 3(a) and the switching member 42B in FIG. 7 etc.). Therefore, the opening 413 is continuously connected to the inner wall portion 412 side through the bulging space portion 422. Accordingly, an open flow path is formed from the inside of the inner wall portion 412 to the DC portion 417.

[0041] On the other hand, when the positioning protrusion 423 is disposed at any of the bulging portions 411b, the bulging space portion 422 formed inside the positioning protrusion 423 is disposed outside the inner wall portion 412 (see the switching member 42D in FIG. 3(a)). The notch 412a is blocked by the side wall portion 421 of the switching member 42 (see the switching member 42B in FIG. 3(a) and the switching member 42D in FIG. 7). Also, the opening 413 is surely blocked by the closing protrusion 421b provided at the front end of the side wall portion 421 extending up to the inner wall of the large diameter portion 417a (see also the switching member 42D in FIG. 7). Thus, the side wall portion 421 can close the opening 413 which is the inlet of the flow path on the confluence portion 418 side.

[0042] After placing the switching member 42 on each recess 411, the support member 43 shown in Fig. 6(a) etc. is placed from the rear side of the main body 41. At this time, the support member 43 is inserted through the engaging projection 415c on the main body 41 side from the front into the introduction part 433b of the inner wall part 433 where the engaged projection 433a is not provided, so that the front surface part 43b of the support member 43 and the contact part 415a of the main body 41 are brought into contact with each other. Then, when the support member 43 is rotated in the clockwise direction as viewed from the rear with the front surface part 43b and the contact part 415a in contact, the engaging projection 415c overlaps the engaged projection 433a and is stably fixed to the main body 41. As a result, as shown in Fig. 7, the front surface part 43b of the support member 43 is located behind the flange part 425 of the switching member 42, and the switching member 42 is also stably supported in a state where its movement is restricted with respect to the main body 41.

[0043] The switching member 42 can be selectively arranged in an arbitrary state of open or closed state in the notch 412a (or the opening 413) on the main body 41 side. Therefore, the intermediate member 4 can function as an opening and closing part that easily switches the opening and closing of the flow path by relatively rotating the switching member 42 around the axis P. This opening and closing part is provided inside the plurality of supply port parts 44 arranged in parallel.

[0044] On the rear surface part 43a side of the intermediate member 4 shown in Fig. 3(a), the supply port part 44 is provided by the switching member 42 and the cylindrical wall part 432. A plurality of containers 3 containing the cream-like substance 30 can be connected to the supply port part 44. Containers 3A to 3D containing different types (for example, different colors) of cream-like substances 30A to 30D are connected to the respective supply port parts 44A to 44D.

[0045] The connection of the container 3 is performed by inserting the connection part 32 into the supply port part 44 and screwing and fastening the male screw part 322a (see Fig. 2) to the female screw part 421a of the switching member 42. Note that the container 3 may be connected only to the supply port part 44 corresponding to the flow path in the open state by the switching member 42. In Fig. 7, the containers 3A to 3D are connected to the four supply port parts 44A to 44D regardless of whether the flow path is in the open state or the closed state.

[0046] Also, a base 5 is attached to a conduit portion 416 provided on the front side of the intermediate member 4. The conduit portion 416 and the base 5 are fixed by screwing a male screw portion 416a into a female screw portion 541. A confluence portion 418 of a flow path provided at the front end portion of the conduit portion 416 is disposed inside the base 5 as shown in FIG. 7.

[0047] Next, a usage example of the squeezer 2 will be described with reference to FIGS. 8 to 10. Here, an example of creating a cream decorative body 301 colored in four colors using containers 3 containing different colored cream-like substances 30A to 30D will be described. Therefore, each opening / closing part (switching members 42A to 42D) corresponding to the flow paths of the respective cream-like substances 30A to 30D are all set to an open state as shown in FIGS. 8 to 10. Note that FIGS. 8 to 10 show the cream-like substances 30B and 30D and their flow paths.

[0048] First, in FIG. 8, the user brings the opening 531 close to the formed surface 71 of the pedestal 7 with the base 5 of the squeezer 2 facing downward. When the user moves the cream-like substances 30A to 30D contained in the containers 3A to 3D toward the base 5 to squeeze them out, the cream-like substances 30A to 30D flow into the direct current portion 417 through the space in the bulging space portion 422 of the switching member 42 installed in the open state. The cream-like substances 30A to 30D that have flowed into each direct current portion 417 move in parallel toward the confluence portion 418 side (base 5 side). Then, the respective cream-like substances 30A to 30D that have moved inside the direct current portion 417 merge at the confluence portion 418 provided at the front end of the conduit portion 416, integrate with a substantially uniform cross-sectional ratio, and move toward the opening 531 side of the base 5.

[0049] After that, as shown in FIG. 9, the integrated cream-like material 30 is extruded onto the surface 71 to be formed. After an appropriate amount of the cream-like material 30 is extruded, as shown in FIG. 10, the user separates the squeezing tool 2 from the surface 71 to be formed. When the squeezing tool 2 is pulled up, near the axis P of the cream-like material 30 adhering to the surface 71 to be formed, it is pulled upward by the cream-like material 30 adhering to the side of the base 5 that moves away, and a top portion is formed. Thereby, a three-dimensional cream decoration 301 having a corner at the center is created. The cream decoration 301 includes four-color cream-like materials 30A to 30D (the cream-like material 30C is arranged on the back side in FIG. 10) that are radially partitioned and colored when viewed from above. Therefore, a cream decoration 301 rich in variations with multiple colors can be easily created.

[0050] After that, the cream decoration 301 is dried for a predetermined time to harden to a hardness that can be used for storage or as a decoration.

[0051] In FIGS. 8 to 10, an example of using the squeezing tool 2 arranged to be substantially perpendicular to the surface 71 to be formed of the pedestal 7 has been described. However, depending on the shape of the cream decoration 301 to be created, the squeezing tool 2 may be used in an inclined manner.

[0052] Also, the user may extrude the cream-like material 30 while rotating the squeezing tool 2 around the axis P of the squeezing tool 2 with the center of the opening 531 as the rotation axis. Thereby, a cream decoration 301 having a spiral-shaped rotated color pattern can be formed. In addition, by adjusting the extrusion amount of the cream-like material 30, the extrusion timing, the distance and angle between the surface 71 to be formed and the base 5, etc., cream decorations with various shapes and color patterns can be created. Also, the squeezing tool 2 is not limited to decorating the pedestal 7 exemplified as the object to be decorated, and various forms of cream molded bodies may be created using the cream-like material 30.

[0053] Next, the cleaning member 8 of the wringer 2 will be described. The cleaning member 8 shown in FIGS. 11(a) and 11(b) is formed in a long rod shape. The cleaning member 8 has a columnar portion 81, a first protrusion 82 provided on one end side of the columnar portion 81, and a second protrusion 83 provided on the opposite end side of the first protrusion 82. Most of the columnar portion 81 is formed into a column having a fan-shaped cross section with a central angle of about 90 degrees. Also, on a part of the columnar portion 81 on the second protrusion 83 side, a side surface protrusion 811 protruding from the curved side surface side is provided. The cross section of the columnar portion 81 where the side surface protrusion 811 is located is a substantially regular square.

[0054] FIG. 12 is a diagram showing a state in which the DC portion 417 in the main body portion 41 is cleaned by the cleaning member 8. After use, for the wringer 2, each container 3A to 3D and the base 5 are removed, and the intermediate member 4 is also disassembled. Since the switching member 42 of the base 5 and the intermediate member 4 is configured as a short cylindrical shape, it can be cleaned relatively easily. Also, since the support member 43 is also configured as a plate shape, it can be cleaned relatively easily. On the other hand, since the DC portion 417 of the main body portion 41 is provided in a long shape, by using the rod-shaped cleaning member 8, it can be easily cleaned as shown below.

[0055] When cleaning the opening 417d side of the DC portion 417, the first protrusion 82 side of the cleaning member 8 is inserted from the opening 417d. At this time, the cleaning member 8 arranges the root portion 812 sandwiched between the flat side surfaces in the columnar portion 81 toward the axis P side inside the DC portion 417 (see also the cross-sectional view XIIa-XIIa of the conduit portion 416). When the cleaning member 8 is inserted upward in FIG. 12, the first protrusion 82 side protrudes from the opening 413. The side surface 821 with a large curvature of the first protrusion 82 (see also FIG. 11(a)) substantially abuts against the curved inner edge 413a (see FIG. 11(b)) on the axis P side of the opening 413. Therefore, by inserting and extracting the cleaning member 8 from the end on the first protrusion 82 side into the opening 417d of the DC portion 417, mainly the inner peripheral surface of the small diameter portion 417c, and the reduced width portion 417b, the large diameter portion 417a, and the inner edge 413a can be easily cleaned.

[0056] Also, when cleaning the opening 413 side of the DC section 417, insert the second protrusion 83 side of the cleaning member 8 from the opening 413. At this time, the cleaning member 8 is disposed in the large-diameter portion 417a by substantially bringing the concave and curved side surface 831 of the second protrusion 83 into surface contact with the inner edge 413b of the opening 413 (see also Fig. 4(b)) facing the notch portion 412a. (See also the cross-sectional view taken along line XIIb-XIIb of the conduit portion 416). When the cleaning member 8 is inserted downward in Fig. 12, the tip of the second protrusion 83 abuts against the inclined surface of the reduced-width portion 417b. Also, by inclining the first protrusion 82 side radially outward with respect to the axis P, the tip of the second protrusion 83 can be further moved downward in Fig. 12 while being in sliding contact with the inclined surface of the reduced-width portion 417b.

[0057] Therefore, by inserting the cleaning member 8 into the opening 413 of the DC section 417 from the end on the second protrusion 83 side and performing the insertion and extraction operation, mainly the inner peripheral surface on the inner edge 413b side of the large-diameter portion 417a and the inclined surface of the reduced-width portion 417b can be easily cleaned.

[0058] As described above, the embodiments of the present invention have been described. However, the present invention is not limited to the above embodiments and can be implemented in various modes. For example, in the present embodiment, an example using the switching member 42 as the opening / closing portion has been shown. However, as the opening / closing portion, a shutter member having another shape (for example, a plate shape) capable of opening and closing the opening 413 on the DC section 417 side may be used. The shutter member can also be separate from the female screw portion 421a that fixes the container 3.

[0059] Also, the confluence portion 418 is not limited to being disposed inside the base 5 of the constriction tool 2, and may be provided in the middle of the conduit portion 416 on the opening / closing portion side closer to the base 5 than the base 5, or may be provided near the opening 531 of the base 5.

[0060] Also, the shape of the opening 531 can be a star shape with the number of star tops appropriately increased or decreased, in addition to the eight-star cut shape. Also, as the shape of the opening 531, other shapes such as a round shape or a polygon may be applied.

[0061] According to the embodiments of the present invention as described above, it is possible to provide a squeezing tool in the following aspects.

[0062] The squeezing tool according to the first aspect includes a plurality of supply ports connectable to a container containing a cream-like substance, a merging portion that merges the flow paths from each of the supply ports, and a nozzle that discharges the cream-like substance merged by the merging portion.

[0063] According to this configuration, since the cream-like substance 30 arbitrarily selected from a plurality of types can be squeezed out from the squeezing tool 2, it is possible to provide a squeezing tool capable of easily creating a cream molded body rich in variations.

[0064] Also, the first In the squeezing tool according to the aspect, an opening / closing portion for switching the opening and closing of the flow path of the cream-like substance is provided between the supply port and the merging portion.

[0065] According to this configuration, the squeezing tool 2 can arbitrarily select a combination of the cream-like substances 30 to be used among the installed containers 3 to create a cream molded body.

[0066] Furthermore, the first In the squeezing tool according to the aspect, the opening / closing portion is an annular switching member having a side wall portion that closes the inlet of the flow path toward the merging portion side and an opening portion that opens the inlet when the side wall portion is interrupted, and the switching member switches the opening and closing of the flow path by being relatively rotated around an axis.

[0067] According to this configuration, the opening and closing of the opening / closing portion can be switched by a simple method of changing the installation direction of the switching member 42.

[0068] And, the first In the squeezing tool according to the aspect, the plurality of supply ports are arranged side by side, and the opening / closing portion is provided inside the plurality of supply ports.

[0069] According to this configuration, the flow path from each supply port 44 to the confluence part 418 can be shortened. Therefore, after using the extrusion tool 2, the amount of the cream-like substance 30 remaining in the flow path from the supply port 44 to the die 5 side can be reduced, and the labor for cleaning and the amount of the cream-like substance 30 to be discarded can be reduced.

[0070] Also, the second In the extrusion tool according to this aspect, a direct current part for translating the cream-like substance supplied from each supply port is provided between the supply port and the confluence part.

[0071] According to this configuration, the cream-like substance 30 can be extruded from the die 5 while stably maintaining the cross-sectional ratio of the cream-like substance 30 that is joined by the confluence part 418 and extruded integrally.

[0072] Furthermore, the third In the extrusion tool according to this aspect, the direct current part has a width-reducing part including an inclined surface.

[0073] According to this configuration, the flow path resistance of the cream-like substance 30 in the direct current part 417 can be reduced, and the cream-like substance 30 flowing in from the opening / closing part side can be smoothly flowed in the direct current part 417.
