Note that the modeled object is capable of holding the shape for at least a fixed time.

Japanese Patent No. 6274899

  However, with such a modeling head, the modeled object cannot be returned to the supply surface side through the molding hole over time. For example, in the case where the modeled object is foamy, when the modeled object is returned to a liquid state with the passage of time and collapses, the liquid content cannot be returned to the supply surface side.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a modeling head that can return a modeled object on a modeling surface to a supply surface side through a molding hole over time.

  The present invention employs the following means in order to solve the above problems. That is, the modeling head of the present invention has a top wall portion that is disposed above the discharge hole through which the contents are discharged, and has a forming hole that penetrates in the vertical direction. An exterior body that discharges the contents that have passed through the molding hole to a modeling surface facing upward, a middle dish that is disposed in the exterior body and is movable in the vertical direction with respect to the exterior body, and the middle dish The discharge hole is fixed to the supply surface by moving the inner tray downward with respect to the exterior body, the fixed upper surface being close to or in contact with the supply surface facing downward in the top wall portion. An impregnation body that defines a diffusion chamber that diffuses the contents from the supply surface along the supply surface and supplies the diffusion holes to the molding hole, and the molding passes through the molding hole to allow the contents to pass through the molding hole. A model is formed on the surface.

  In this invention, since the impregnated body is fixed to the inner dish and this impregnated body is in contact with or close to the supply surface, the impregnated body formed on the modeling surface is passed through the molding hole over time. Can be absorbed. Here, when the content is a volatilizing agent, the volatilizing component can be volatilized to the outside through the molding hole from the content absorbed by the impregnated body, and if necessary, the modeling formed on the modeling surface Volatile components of contents can be volatilized out of the object.

In the present invention, the inner plate may be provided with a deformation regulating piece that abuts on the supply surface and regulates the deformation of the impregnated body.
In this invention, since the deformation restricting piece comes into contact with the supply surface, the impregnated body fixed to the intermediate plate is pressed against the supply surface when the intermediate plate is moved upward with respect to the exterior body, and is deformed excessively. Is suppressed. In particular, when the inner tray is constantly biased upward with respect to the exterior body, it is possible to effectively suppress the impregnated body from being pressed against the supply surface. Thereby, for example, when the impregnated body is formed of a compressible and deformable material such as a sponge body, it is possible to suppress the impregnated body from absorbing the contents due to the collapse of the bubbles in the impregnated body. In addition, when the inner tray is lowered with respect to the exterior body, the impregnated body is restored and deformed so that the contents discharged from the discharge holes are not sucked into the impregnated body and become difficult to diffuse in the diffusion chamber. It can suppress that the formation accuracy of a molded article falls.

Further, in the present invention, the impregnated body is formed with a communication hole that penetrates in the vertical direction and communicates with the discharge hole, and the inner plate is provided with a guide tube portion inserted into the communication hole. May be.
In this invention, the content discharged from the discharge hole flows into the diffusion chamber through the guide tube portion inserted in the through hole formed in the impregnated body, so that the content is shaped through the molding hole without passing through the impregnated body. Can form things.

Further, in the present invention, a protruding wall portion surrounding the molding hole in a top view may be extended on the modeling surface of the top wall portion.
In this invention, when the shaped article is returned to a liquid state with the passage of time, it is possible to prevent the liquid content from flowing down to the outside of the exterior body.

  According to the modeling head according to the present invention, since the impregnated body is fixed to the inner dish, the formed model can be absorbed by the impregnated body over time.

The impregnated body 33 is formed of a porous material such as a filter paper or a sponge body. The upper surface of the impregnated body 33 is in contact with or close to the supply surface 41B of the top wall portion 41 of the exterior body 31, and the outer peripheral surface of the impregnated body 33 is in contact with the inner peripheral surface of the peripheral wall portion 42 of the exterior body 31. Or close. Here, that the upper surface of the impregnated body 33 is close to the supply surface 41B means that the object formed on the modeling surface 41A is separated to the extent that it can be sucked in through the molding hole 41C over time. I mean. In addition, a communication hole 33A penetrating in the vertical direction is formed at the center of the impregnated body 33, and a guide cylinder portion 64 is inserted into the communication hole 33A.
The urging spring 20 has a lower end supported by the fixing member 6 and an upper end supported by the inner tray 32. Therefore, the biasing spring 20 biases the inner tray 32 upward with respect to the exterior body 31.

Next, a method of using the modeling head 1 having the above configuration will be described.
First, as shown in FIG. 6, when the operation plate portion 67 is pushed down against the urging force of the urging spring 20 to lower the inner tray 32 with respect to the exterior body 31, the locking rib portion 65 </ b> A of the inner tray 32. Comes into contact with the upper end of the stem 21 from above. Further, a diffusion chamber S is defined between the upper surface of the impregnated body 33 and the supply surface 41B of the top wall portion 41 of the exterior body 31. Here, when the inner tray 32 is further lowered with respect to the exterior body 31, the stem 21 descends against the upward biasing force, so that the contents in the container main body 3 are transferred to the upper end opening 21 </ b> A of the stem 21, It flows into the diffusion chamber S through the inside of the flow hole 61 </ b> A and the guide cylinder portion 64. Here, since the content discharged from the upper end opening 21A of the stem 21 flows into the diffusion chamber S through the guide cylinder portion 64, it is suppressed from being sucked into the impregnation body 33 before reaching the diffusion chamber S. .

The contents flowing into the diffusion chamber S flow in the vertical direction on the outer peripheral surface of the core body 41D and are held by the core body 41D. At this time, the contents are held by the core body 41D so as to form a circle centered on the core body 41D in a plan view, for example. When the supply amount of the content to the core body 41D increases as the discharge amount of the content from the stem 21 increases, the content grows on the core body 41D and gradually expands outward in the radial direction. Thereby, coupled with the diffusion chamber S being formed in a flat shape, the contents supplied into the diffusion chamber S are diffused in the radial direction and supplied to the plurality of molding holes 41C.
The contents flowing into the forming hole 41C flow toward the modeling surface 41A of the top wall portion 41. Then, the contents that have passed through the plurality of molding holes 41C are discharged to the modeling surface 41A to form a plurality of modeling pieces, and the modeling objects are formed by combining the plurality of modeling pieces.

  Thereafter, as shown in FIG. 7, when the push-down operation of the operation plate portion 67 is released, the stem 21 is restored and deformed upward, and the inner tray 32 is directed upward with respect to the exterior body 31 by the biasing spring 20. To restore displacement. Thus, the upper surface of the impregnated body 33 comes into contact with or is close to the supply surface 41B of the top wall portion 41 of the exterior body 31. Here, a deformation restricting piece 63 and a guide cylinder part 64 are formed on the top plate part 61 of the inner tray main body 51, and the upper ends of the deformation restricting piece 63 and the guide cylinder part 64 are on the top wall part 41 of the exterior body 31. Since it contacts the supply surface 41B, the impregnated body 33 is prevented from being pressed against the supply surface 41B of the top wall portion 41 of the exterior body 31.

The modeled object formed on the modeling surface 41A is absorbed by the impregnated body 33 through the molding hole 41C as time passes. Further, even when the foam-like shaped article returns to a liquid state and collapses over time, it is absorbed by the impregnated body 33 through the molding hole 41C. Here, since the upper surface of the impregnated body 33 is close to or in contact with the supply surface 41B of the top wall portion 41 of the exterior body 31, the content returning through the molding hole 41C is efficiently absorbed by the impregnated body 33. . The contents absorbed in the impregnated body 33 are volatilized to the outside of the discharge container 2 through the molding hole 41C and the volatilization window part 42B. In addition, you may volatilize also from the molded article formed on the modeling surface 41A.
Further, since the modeled object on the modeling surface 41A is absorbed by the impregnated body 33 with the passage of time, it is suppressed that the contents remain on the modeling surface 41A for a long time even when it returns to the liquid state. Thereby, it is suppressed that impurities, such as dirt, adhere to modeling surface 41A and molding hole 41C, and it becomes difficult to form a modeling object of a desired shape next when manipulating tray 32 and forming a modeling object. It is suppressed. Furthermore, even if the modeled object is returned to the liquid state on the modeled surface 41 </ b> A, the protruding wall part 41 </ b> E prevents the liquid content from flowing down to the outside of the exterior body 31.
The modeling head 1 is used as described above.

As described above, according to the modeling head 1 according to the present embodiment, the modeled object formed on the modeling surface 41A can be absorbed by the impregnated body 33 through the molding hole 41C with the passage of time. Moreover, since the content is a volatilizing agent, the content absorbed by the impregnated body 33 can be volatilized to the outside of the discharge container 2 through the molding hole 41C and the volatilization window portion 42B. Furthermore, you may volatilize the volatilization component to the exterior of the discharge container 2 from the molded article formed on the modeling surface 41A as needed.
Further, since the deformation regulating piece 63 and the guide cylinder portion 64 are in contact with the supply surface 41B, the impregnated body 33 is not affected even when the inner tray 32 is constantly urged upward with respect to the exterior body 31 by the urging spring 20. It is possible to suppress compressive deformation by being pressed against the supply surface 41B. Thereby, it can suppress that the impregnated body 33 is compressed and it is inhibited from absorbing a modeling thing with progress of time. Further, the impregnated body 33 is restored and deformed when the inner tray 32 is lowered with respect to the exterior body 31, whereby the contents discharged from the stem 21 are sucked into the impregnated body 33 and are not easily diffused in the diffusion chamber S. It can suppress that it becomes and it can suppress that the shaping | molding precision of a molded article falls.
Furthermore, since the content discharged from the discharger 5 flows into the diffusion chamber S through the guide tube portion 64, the content is prevented from being sucked into the impregnating body 33 before reaching the diffusion chamber S.
In addition, since the projecting wall 41E is provided on the modeling surface 41A, even if the modeling object formed on the modeling surface 41A is returned to a liquid state with the passage of time, the contents returned to the liquid state are the exterior body 31. It can be suppressed from flowing out of.

  A plurality of first sliding protrusions 118 </ b> A protruding inward in the radial direction are formed on the inner peripheral surface of the first conversion cylinder part 118 at intervals in the circumferential direction. 118 A of 1st sliding protrusions have comprised the right-angled triangle shape seeing from radial direction, the 1st perpendicular | vertical surface 118B extended in an up-down direction, and one direction (clockwise) from the upper end of the 1st perpendicular | vertical surface 118B. 1st inclined surface 118C inclined so that it may go below as it goes to (rotating direction). An upper end portion of the first inclined surface 118C is a first curved surface 118D that protrudes downward.

The exterior body 103 has a circular top wall portion 41 and a cylindrical peripheral wall portion 121 in plan view. The top wall portion 41 and the peripheral wall portion 121 are disposed coaxially with the container axis O.
On the inner peripheral surface of the lower end portion of the peripheral wall 121, a second mounting protrusion 122 is formed that protrudes inward in the radial direction and engages with the first mounting protrusion 119 of the protruding cylindrical portion 116 from below. ing. In addition, a plurality of operation protrusions 121 </ b> A are provided on the outer peripheral surface of the peripheral wall 121 in the circumferential direction that protrudes outward in the radial direction. The outer surface of the operation protrusion 121A is inclined so as to go inward in the radial direction as it proceeds clockwise in plan view.
In addition, a plurality of rotation rib portions 121B extending in the vertical direction are formed on the inner peripheral surface of the peripheral wall portion 121 at intervals in the circumferential direction. Furthermore, a lower locking portion 121C is formed on the inner peripheral surface of the lower end portion of the peripheral wall portion 121. The lower locking portion 121C protrudes toward the inside in the radial direction and locks the upper locking portion 119A from below.

The middle tray 104 includes a disk-shaped top plate portion 131 in a plan view and a cylindrical second conversion tube portion 132 that extends downward from the lower surface of the top plate portion 131. The top plate part 131 and the second conversion cylinder part 132 are arranged coaxially with the container axis O.
In the outer peripheral edge portion of the top plate portion 131, there is a rotation recess 131A that is recessed inward in the radial direction and that is locked in the circumferential direction with respect to the rotation rib portion 121B formed in the peripheral wall portion 121. Are formed. As a result, the inner tray 104 is restricted from rotating in the circumferential direction with respect to the exterior body 103.

The outer diameter of the second conversion cylinder part 132 is smaller than the inner diameter of the first conversion cylinder part 118, and the lower end part of the second conversion cylinder part 132 is disposed inside the first conversion cylinder part 118. ing. A plurality of second sliding protrusions 132 </ b> A protruding outward in the radial direction are formed on the outer peripheral surface of the second conversion cylinder part 132 at intervals in the circumferential direction. Similarly to the first sliding protrusion 118A, the second sliding protrusion 132A has a right triangle shape when viewed from the radial direction, and the second vertical surface 132B extending in the vertical direction and the second vertical surface A second inclined surface 132C that is inclined downward from the lower end of 132B in the clockwise direction. A connecting portion between the second vertical surface 132B and the second inclined surface 132C is a second curved surface 132D that protrudes upward.
The second sliding protrusion 132A is larger than the first sliding protrusion 118A as a whole, and has a shape substantially similar to the first sliding protrusion 118A. Further, the angle formed by the second vertical surface 132B and the second inclined surface 132C is equal to the angle formed by the first vertical surface 118B and the first inclined surface 118C.

The first inclined surface 118 </ b> C and the second inclined surface 132 </ b> C are allowed to rotate in the clockwise direction in the plan view with respect to the container body 101 of the inner tray 104. Further, by the upward biasing force of the first vertical surface 118B and the second vertical surface 132B and the upper biasing force on the middle plate 104 by the biasing spring 20, the other direction (counterclockwise) in the circumferential direction in the plan view of the middle plate 104 with respect to the container body 4 Direction) is restricted. As described above, the first sliding protrusion 118A, the second sliding protrusion 132A, and the biasing spring 20 constitute a ratchet mechanism that allows the circumferential rotation of the inner tray 104 relative to the container body 4 only in the clockwise direction. is doing. The ratchet mechanism may be configured to allow counterclockwise rotation of the intermediate tray 104 relative to the container body 4 in a plan view and restrict clockwise rotation.
The circumferential interval between the second sliding protrusions 132A is larger than the circumferential width of the first sliding protrusion 118A. As a result, circumferential play occurs between the second sliding protrusion 132A and the first sliding protrusion 118A, and when an excessively large rotational force is applied to the inner tray 104, for example, the first sliding It is suppressed that the protrusion 118A continuously gets over the second sliding protrusion 132A in the circumferential direction and the contents are continuously discharged.
Note that the guide plate 64 is not provided in the inner plate 104 as in the modeling head 1 according to the first embodiment.

The method of using the modeling head 100 having the above configuration is the same as the method of using the modeling head 1 according to the first embodiment described above.
When the exterior body 103 is rotated in the clockwise direction with respect to the container body 101, the inner tray 104 rotates in the clockwise direction with respect to the fixed member 102 integrally with the exterior body 103, and is formed in the second conversion cylinder portion 132. The formed second inclined surface 132 </ b> C contacts the first inclined surface 118 </ b> C formed in the first conversion cylinder portion 118 in the circumferential direction. When the exterior body 103 is further rotated in the clockwise direction together with the inner tray 104 in this state, the second sliding protrusion 132A descends along the first inclined surface 118C as indicated by an arrow A1 in FIG. As a result, as shown in FIG. 11, the middle tray 104 descends against the upward biasing force of the biasing spring 20, and the inner peripheral edge of the top plate portion 131 of the middle tray 104 lowers the stem 21. A diffusion chamber S is defined between the impregnated body 33 and the exterior body 103. Then, the contents in the container body 3 flow into the diffusion chamber S and flow toward the modeling surface 41A through the molding holes 41C to form a modeled object.

When the exterior body 103 is further rotated in the clockwise direction with respect to the container body 101, the second sliding protrusion 132A becomes the first inclined surface of the first sliding protrusion 118A as shown by an arrow A2 in FIG. It reaches the lower end of 118C and gets over first curved surface 118D in the clockwise direction. Then, as shown in FIG. 12, the intermediate tray 104 is raised by the upward biasing force of the biasing spring 20.
In the case of discharging the contents again, an operation of rotating the exterior body 103 in the same clockwise direction is performed.

  Even with the modeling head 100 configured as described above, the same effects as those of the modeling head 1 according to the first embodiment described above can be obtained.

For example, in the first embodiment, the guide tube portion may not be provided, and similarly, the guide tube portion may be provided in the second embodiment.
The contents are not limited to a volatile agent as long as the shape can be maintained for at least a certain time after discharge, but by using a volatile agent, the contents absorbed by the impregnated body are passed through the molding hole and the volatile window portion. Since it is volatilized outside the discharge container, it remains difficult to remain in the impregnated body.
Only one of the deformation restricting piece and the guide tube portion may be provided, or both may not be provided.
The protruding wall portion collectively surrounds the plurality of forming holes from the outside in the radial direction in plan view, but may have other shapes such as separately surrounding the forming holes. Further, the protruding wall portion may not be provided.
The middle dish is biased upward by the biasing spring, but may not always be biased upward by the biasing spring. Further, by adjusting the urging spring, the upper surface of the impregnated body may be in contact with or close to the supply surface when the pushing of the inner pan against the container body is released, but may not be pressed against the supply surface.
The mechanism for moving the middle dish up and down with respect to the exterior body is not limited to the mechanism for operating the manipulation body of the middle dish or the mechanism for rotating the middle dish in the circumferential direction as described above, but may be other mechanisms.
The impregnated body is not limited to a material that can be compressively deformed in the vertical direction, such as a filter paper or a sponge body, and may be formed of a material that does not compressively deform as long as it is a material that can absorb a modeled object over time.
Although the aerosol can in which the liquid content is accommodated is adopted as the container body, a container body having a discharge mechanism other than the aerosol can may be used.
In the description of each component member, “cylindrical” is described, but other shapes such as an elliptical shape, other polygonal shapes such as a triangular shape and a rectangular shape may be used as appropriate.
