[0124] Hereinafter, embodiments of the present invention will be described based on the drawings. Figure 1 1 is a diagram showing a decorative body forming toy set 1. The decorative body forming toy set 1 includes an extruder 2 and a base 7. A user can extruder 2 from the rear ( Figure 1 ) to the front ( Figure 1 The creamy substance 30 (30A to 30D) filled in each container 3 (3A to 3D) of the extruder 2 is squeezed by moving the extruder 2 in a manner such that the creamy substance 30 can be squeezed out (pushed out) from the opening 531 of the end cap 5. The squeezed creamy substance 30 can be placed on the formed surface 71 of the base 7 to make a decorative toy such as a Western pastry decorated with simulated fresh cream. Figure 1 The illustrated base 7 is formed in a short-sized cylindrical shape.

[0125] Hereinafter, a toy set 1 for forming a decorative body mainly for use in a game will be described, in which a creamy resin is used as the creamy substance 30 and the extruder 2 is used as a decorative body toy. In addition, the extruder 2 of this embodiment may use a creamy substance such as whipped cream generally used for food instead of the creamy resin. In this case, the extruder 2 can be used for serving food such as sponge cake on a plate, etc., instead of the base 7.

[0126] Figure 2: is an exploded perspective view of the extrusion device 2. In the following description of the extrusion device 2, the container 3 side is referred to as the rear, and the cover 5 side is referred to as the front. The extrusion device 2 includes a container 3, an intermediate member 4, a cover 5, and a cap 6. A bag body 31 containing a cream-like substance 30 is provided at the rear most 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 thermocompression bonding or the like. The rear end of the bag body 31 is sealed by bonding the two overlapping sheet members 311 by thermocompression bonding or the like (details are not shown).

[0127] The container 3 is connected to a plurality of supply ports 44 of the intermediate member 4. The extruder 2 of this embodiment uses a plurality of creamy substances 30A to 30D (see Figure 1 ) are four containers 3A to 3D built into a bag body 31. The creamy substance 30 filled in the bag body 31 simulates whipped cream and may contain, for example, a synthetic binder, acrylic resin, cellulose, a stabilizer, a preservative, etc. Therefore, the creamy substance 30 solidifies when it dries in contact with air. The creamy substances 30A to 30D of this embodiment are colored with different colors by adding coloring materials.

[0128] In addition, the bag bodies 31 of the containers 3A to 3D are tied together by detachable binding bands 33 (see Figure 1 By moving the bundling position forward as the amount of the cream-like substances 30A to 30D decreases, it is possible to reduce the backward flow (backflow) of the cream-like substances 30A to 30D when the extruder 2 is used.

[0129] exist Figure 2 In the embodiment, the connecting portion 32 has a rear section 321 with a large outer diameter and a front section 322 with a small outer diameter, and the whole is formed into a substantially cylindrical shape. A flange portion 321a is formed circumferentially at the rear end edge of the rear section 321. In addition, a plurality of protruding diameter portions 321b having a larger diameter than the outer peripheral side surface are formed circumferentially on the outer peripheral side surface of the rear section 321. A plurality of protruding diameter portions 321b are arranged in the front-rear direction.

[0130] The bag body 31 has an opening 312 at the front end. The opening 312 is connected to the connection part 32. The opening 312 is formed by bonding the side edges of the two sheet members 311 except the front ends to each other. In addition, near the opening 312, the side edges are bonded in such a way that the inner edge of the opening 312 is in close contact with the rear section 321 of the connection part 32. The protruding diameter portion 321b provided in the rear section 321 is in close contact with the inner side of the opening 312, so that the creamy substance 30 can be prevented from leaking from the gap between the outer peripheral side of the rear section 321 and the opening 312.

[0131] An external thread portion 322a is formed on the outer peripheral side surface of the front section 322. A flat convex locking protrusion 322c is formed near the terminal end of the groove portion 322b of the external thread portion 322a. The locking protrusion 322c is formed to be lower than the thread of the external thread portion 322a.

The intermediate member 4 includes a main body 41, a switching member 42 disposed behind the main body 41, and a support member 43 that supports the switching member 42 in a contained state relative to the main body 41.

[0133] like Figure 4 As shown in (a), the main body 41 is formed into a circular thick plate. A recess 411 capable of accommodating the switching member 42 in a predetermined direction is provided on the rear surface 41a of the main body 41. A plurality of recesses 411 are arranged around the axis P at the center of the main body 41. In this embodiment, the recesses 411 are provided at four locations.

[0134] The recess 411 is formed into a substantially circular groove shape. A bulge 411a (an example of a first bulge) and a bulge 411b (an example of a second bulge) bulging outward in the radial direction of the recess 411 are provided on a portion of the inner circumferential surface of the recess 411. The bulge 411a is arranged on the axis P side of the main body 41. The bulges 411b provided at two locations are arranged at a position farther away from the bulge 411a relative to the axis P of the main body 41. The bulges 411a and bulges 411b are arranged at substantially equal intervals around the outer circumference of the recess 411 (approximately equal angles around the axis P of the recess 411).

[0135] The bottom portion of the recess 411 is formed in a flat shape. A C-shaped inner wall portion 412 is provided from the bottom portion of the recess 411. The inner wall portion 412 is arranged separately from the inner peripheral surface of the recess 411. In addition, the inner wall portion 412 is formed to be lower than the rear surface portion 41a of the main body 41. The inner wall portion 412 has a notch portion 412a on the side of the bulging portion 411a in which a part is cut away. On the bottom portion of the recess 411, an opening portion 413 (an example of a first opening portion) connected to a straight flow portion 417 as a flow path for the creamy substance 30 is provided on the side of the bulging portion 411a (the axis P side) relative to the notch portion 412a (see Figure 4 (b)) The opening 413 is arranged so as to include a part of the bulging portion 411a.

[0136] In addition, on the bottom surface of the recessed portion 411, a long groove-shaped engaging groove 414 is provided in the direction along the inner wall portion 412 on the side closer to the bulging portion 411b than the inner wall portion 412 (see also Figure 4 (b)) The engaging grooves 414 are provided corresponding to the protruding portions 411b.

[0137] The outer peripheral portion 415 of the main body 41 has an annular abutment portion 415a at a position radially outward relative to the axis P and rearward relative to the rear surface portion 41a. The abutment portion 415a is formed into a flat surface. In addition, a plurality of engaging protrusions 415c are separately provided at a position further rearward than the abutment portion 415a. The engaging protrusions 415c are provided in a manner protruding inward from the outer peripheral wall portion 415b provided around the outer periphery of the abutment portion 415a. In addition, the engaging protrusions 415c are provided at 4 locations at approximately equal intervals (approximately equal angles around the axis P) in the circumferential direction around the axis P.

[0138] like Figure 3 As shown in (b), a conduit portion 416 is provided on the front side of the main body 41 on the axis P. The hollow cylindrical interior of the conduit portion 416 is divided crosswise by the inner wall to form a plurality of flow paths as direct current portions 417. Therefore, the cross section of each direct current portion 417 is formed into a substantially fan-shaped shape with a right inner angle. A large diameter portion 417a connected to the opening 413 and a width reduction portion 417b (see also FIG. 4 ) formed by tilting a portion of the inner circumference forward from the large diameter portion 417a are provided on the side of the direct current portion 417.

In this embodiment, the positioning protrusion 423 is provided at one location, and the positioning protrusion 424 is provided at two locations. Figure 5 (a) is provided with an internal thread portion 421a. The internal thread portion 421a of this embodiment has a thread tooth formed by a plurality of intermittently arranged protrusions. The protrusions of the intermittently arranged thread teeth are arranged in a staggered manner so as not to overlap in the direction of the axis Q. Therefore, the switching component 42 including the internal thread portion 421a can be formed by a split mold that moves along the direction of the axis Q and can be manufactured by a simple method.

[0142] A flange portion 425 wider than the plate thickness of the side wall portion 421 is provided at the upper end portion of the side wall portion 421. The flange portion 425 is formed in an annular shape in a manner extending radially outward from the rear end portion of the side wall portion 421 relative to the axis Q. In addition, the flange portion 425 is configured in a manner covering the bulging space portion 422 from the rear end side. Therefore, the bulging space portion 422 has an opening portion 422a that is open throughout the axis Q direction (up and down direction) and an opening portion 422b (an example of a second opening portion) that is open on the front side. The opening portion 422a is configured on the notch portion 412a side, thereby being able to open the inlet (opening portion 413) of the flow path on the confluence portion 418 side (refer to Figure 7 ).

[0143] A regular triangle-shaped mark 425a is provided on the upper surface of the flange portion 425 corresponding to the position of the bulging space portion 422 (positioning protrusion 423). By providing the mark 425a, when the switching member 42 is observed from above, the position of the bulging space portion 422 (positioning protrusion 423) as a part of the flow path can be easily grasped.

[0144] In addition, if Figure 5 As shown in (b), at a part of the lower end of the side wall portion 421, two closing protrusions 421b are provided at corresponding locations to the positioning protrusions 424. The closing protrusions 421b have a plate thickness substantially the same as that of the side wall portion 421, and are provided with a width substantially the same as that of the positioning protrusions 424 in the circumferential direction relative to the axis Q. In addition, the side surface of one side of the closing protrusion 421b is continuous with the inner peripheral surface of the side wall portion 421.

[0145] Figure 6 (a) and Figure 6 The support member 43 shown in (b) is formed to have a diameter larger than the main body 41 (see Figure 4 The outer peripheral wall portion 415b of (a) is smaller than the outer diameter of the rear surface portion 41a and is generally disc-shaped. Therefore, the support member 43 can be placed in a state of contact with the contact portion 415a of the main body 41 (see also Figure 7 ).

[0146] The support member 43 is provided with a plurality of circular openings 431 around the axis P. The inner diameter of the opening 431 is set to be substantially the same as the diameter of the side wall 421 of the switching member 42.

Therefore, an open flow path is formed from the inner side of the inner wall 412 to the direct flow portion 417.

[0155] On the other hand, when the positioning protrusion 423 is arranged on any bulging portion 411b (an example of a case where the switching member 42 is accommodated in the recess 411 in the second orientation), the bulging space portion 422 formed on the inner side of the positioning protrusion 423 is arranged on the outer side of the inner wall portion 412 (see Figure 3 (a) of the switching member 42D). The notch 412a is closed by the side wall 421 of the switching member 42 (see Figure 3 (a) the switching member 42B and Figure 7 In addition, the closing protrusion 421b provided at the front end of the side wall portion 421 is arranged to extend over the inner wall of the large diameter portion 417a, so that the opening portion 413 is reliably closed (see also Figure 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.

[0156] After the switching member 42 is placed in each recess 411, the switching member 42 is placed from the rear side of the main body 41. Figure 6 (a) and the like. At this time, the supporting member 43 is configured such that the front surface portion 43b of the supporting member 43 abuts against the abutting portion 415a of the main body 41 by inserting the engaging protrusion 415c on the main body 41 side through the introduction portion 433b in the inner wall portion 433 where the engaging protrusion 433a is not provided from the front. Furthermore, when the supporting member 43 is rotated in the clockwise direction as viewed from the rear in a state where the front surface portion 43b abuts against the abutting portion 415a, the engaging protrusion 415c overlaps with the engaged protrusion 433a, and the supporting member 43 is stably fixed relative to the main body 41. Thus, as Figure 7 As shown, the front surface portion 43 b of the support member 43 is located behind the flange portion 425 of the switching member 42 , and the switching member 42 is also stably supported in a state where the movement thereof is restricted relative to the main body 41 .

[0157] The switching member 42 can selectively configure the notch 412a (or the opening 413) on the side of the main body 41 to an open state or a closed state. 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 configuring the switching member 42 to be relatively rotatable around the axis Q. The opening and closing part is provided on the inner side of the plurality of supply ports 44 arranged side by side.

[0158] exist Figure 3The supply port 44 is provided on the rear surface portion 43a side of the intermediate member 4 shown in (a) via the switching member 42 and the cylindrical wall portion 432. A plurality of containers 3 containing creamy substances 30 can be connected to the supply port 44. Containers 3A to 3D containing creamy substances 30A to 30D of different types (e.g., different colors) are connected to the supply ports 44A to 44D.

[0159] The connection of the container 3 is to insert the connection part 32 into the supply port 44 and make the external thread part 322a (refer to Figure 2 ) is screwed and fastened with the internal thread portion 421a of the switching member 42. In addition, the container 3 can also be connected to the supply port 44 corresponding to the flow path in the open state using only the switching member 42. Figure 7 In the embodiment, regardless of the open state or the closed state of the flow path, the containers 3A to 3D are connected to the supply ports 44A to 44D at the four locations.

[0160] In addition, the cover 5 is mounted on the conduit portion 416 provided on the front side of the intermediate member 4. The conduit portion 416 and the cover 5 are fixed by screwing the external thread portion 416a and the internal thread portion 541 together. Figure 7 As shown, a confluence portion 418 of the flow paths provided at the front end portion of the conduit portion 416 is arranged inside the cover 5 .

[0161] Next, use Figure 8 to Figure 10 The following describes an example of using the extruder 2. Here, the example of using the container 3 containing creamy substances 30A to 30D of different colors to produce a creamy decorative body 301 in four colors is described. Therefore, the opening and closing parts (switching parts 42A to 42D) corresponding to the flow paths of the creamy substances 30A to 30D are as follows: Figure 8 to Figure 10 are set to the open state. Figure 8 to Figure 10 , creamy substances 30B and 30D and their flow paths are shown.

[0162] First, in Figure 8 In the embodiment, the user moves the opening 531 close to the formed surface 71 of the base 7 while the cap 5 of the extruder 2 is facing downward. When the user moves the creamy substances 30A to 30D contained in the containers 3A to 3D to be extruded toward the cap 5 side, the creamy substances 30A to 30D flow into the direct flow section 417 through the space in the bulging space 422 of the switching member 42 set in the open state. The creamy substances 30A to 30D flowing into the direct flow sections 417 move in parallel toward the confluence section 418 side (cap 5 side). Then, the creamy substances 30A to 30D moving in the direct flow sections 417 merge at the confluence section 418 provided at the front end of the conduit section 416, and move toward the opening 531 side of the cap 5 in an integrated manner with a substantially equal cross-sectional ratio.

[0163] Afterwards, if Fig. 9 As shown, the integrated creamy substance 30 is pushed out to the formed surface 71. After pushing out an appropriate amount of the creamy substance 30, as shown in FIG. Fig.10 As shown, the user separates the extruder 2 from the formed surface 71. When the extruder 2 is pulled up, the cream-like substance 30 attached to the formed surface 71 is pulled up near the axis P of the cream-like substance 30 attached to the separated cover 5 to form a top. In this way, a three-dimensional cream decoration 301 having a corner at the center is produced. The cream decoration 301 includes four colors of cream-like substances 30A to 30D (the cream-like substance 30C is arranged at Fig.10 Therefore, it is possible to easily produce a cream decoration body 301 with rich variations in a variety of colors.

[0164] Thereafter, the cream decoration 301 is dried for a predetermined time to harden to a hardness that allows it to be stored and used as a decoration.

[0165] In addition, Figure 8 to Figure 10 In the description, an example is described in which the extruder 2 is arranged substantially perpendicularly to the forming surface 71 of the base 7 for use. However, the extruder 2 may be tilted for use depending on the shape of the cream decoration 301 to be produced.

[0166] In addition, the user can also rotate the extruder 2 around the axis P of the extruder 2 with the center of the opening 531 as the rotation axis and extrude the cream-like substance 30 at the same time. In this way, a cream decoration 301 with a spirally rotating color pattern can be formed. In addition, the extrusion amount of the cream-like substance 30, the timing of extrusion, the distance and angle between the formed surface 71 and the cover 5, etc. can be adjusted to produce cream decorations of various shapes and color patterns. In addition, the extruder 2 is not limited to decorating the base 7 illustrated as the decoration, and various forms of cream moldings can also be produced using the cream-like substance 30.

[0167] Next, the cleaning member 8 of the extrusion tool 2 will be described. Fig.11 (a) and Fig.11 The cleaning member 8 shown in (b) is formed into 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 end side opposite to the first protrusion 82. Most of the columnar portion 81 is formed into a columnar shape having a fan-shaped cross section with a central angle of about 90 degrees. In addition, a side protrusion 811 protruding from the curved side is provided on a part of the side of the second protrusion 83 of the columnar portion 81. The cross section of the columnar portion 81 where the side protrusion 811 is located is a substantially regular quadrilateral.

[0168] Fig.12 1 is a diagram showing the situation of cleaning the direct current section 417 in the main body 41 by using the cleaning member 8. After use, the containers 3A to 3D and the cover 5 of the extruder 2 are removed, and the intermediate member 4 is also disassembled. The cover 5 and the switching member 42 of the intermediate member 4 are configured as short cylindrical shapes, so they can be cleaned relatively easily. In addition, since the supporting member 43 is also configured as a plate, it can be cleaned relatively easily. On the other hand, since the direct current section 417 of the main body 41 is configured as a long strip, it can be easily cleaned by using the rod-shaped cleaning member 8 as shown below.

[0169] When cleaning the opening 417d side of the direct current section 417, the first protrusion 82 side of the cleaning member 8 is inserted from the opening 417d. At this time, the cleaning member 8 is arranged in the direct current section 417 with the tail root 812 sandwiched between the flat side surfaces of the columnar portion 81 facing the axis P side (also refer to the XIIa-XIIa cross-sectional view of the conduit portion 416). Fig.12 When the first protrusion 82 is inserted from the top, the first protrusion 82 protrudes from the opening 413. The side surface 821 of the first protrusion 82 with a large curvature (see also Fig.11 (a)) and the curved inner edge 413a on the axis P side of the opening 413 (see Fig.11 Therefore, by inserting the cleaning member 8 from the end of the first protrusion 82 side into the opening 417d of the DC portion 417 and performing the plugging and pulling operation, it is easy to mainly clean the inner peripheral surface of the small diameter portion 417c, the width reduction portion 417b, the large diameter portion 417a and the inner edge 413a.

[0170] When cleaning the opening 413 side of the direct current portion 417, the second protrusion 83 side of the cleaning member 8 is inserted from the opening 413. At this time, the cleaning member 8 is aligned with the inner edge 413b of the opening 413 (see also FIG. Figure 4 (b)) is disposed in the large diameter portion 417a in contact with the substantially surface thereof (see also the XIIb-XIIb cross-sectional view of the conduit portion 416). Fig.12 When the second protrusion 83 is inserted downward, the tip of the second protrusion 83 abuts against the inclined surface of the width reduction portion 417b. In addition, by making the first protrusion 82 side inclined radially outward relative to the axis P, the tip of the second protrusion 83 can also be moved while sliding in contact with the inclined surface of the width reduction portion 417b. Fig.12 Move further below.

[0171] Therefore, by inserting the cleaning member 8 from the end on the second protrusion 83 side into the opening 413 of the direct current portion 417 and performing the insertion and removal operation, the inner peripheral surface on the inner edge 413b side of the large diameter portion 417a and the inclined surface of the width reduction portion 417b can be easily cleaned.

[0172] The embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments and can be implemented in various ways. For example, in this embodiment, an example of using the switching member 42 as the opening and closing portion is shown, but the opening and closing portion can also use an opening and closing member of another shape (for example, a plate shape) that can open and close the opening portion 413 on the DC portion 417 side. The opening and closing member can also be separated from the internal thread portion 421a of the fixed container 3.

[0173] The merging portion 418 is not limited to being disposed inside the cap 5 of the extrusion tool 2 , but may be disposed midway on the opening and closing portion side of the duct portion 416 relative to the cap 5 , or may be disposed near the opening 531 of the cap 5 .

[0174] In addition, the shape of the opening 531 can be a star shape in which the number of the tops of the star is appropriately increased or decreased, in addition to the 8-cut star shape. In addition, the shape of the opening 531 can also be applied to other shapes such as a circle or a polygon.
