Description

Technical Field

[0001] The present invention relates to a stick-shaped cosmetic manufacturing device for manufacturing stick-shaped cosmetics such as stick-shaped lipstick, a middle plate for stick-shaped cosmetics and a method for manufacturing stick-shaped cosmetics. Background Art

[0002] Stick-shaped cosmetics such as stick lipsticks include a stick-shaped cosmetic main body and a cosmetic container that accommodates and holds the cosmetic main body via a middle plate. The cosmetic main body is taken out of the cosmetic container for use by sliding the middle plate up and down in the cosmetic container.

[0003] There are at least two methods for making cosmetic containers for stick-shaped cosmetics. One method is to insert a center plate when manufacturing the cosmetic container, which is called an integrated center plate method. As a method for manufacturing stick-shaped cosmetics using a cosmetic container using an integrated center plate method, the following methods are known: a method in which, after a mold of the cosmetic body is mounted on the front end of the cosmetic container, the material of the cosmetic body softened or liquefied by heating is filled from a hole formed in the bottom of the cosmetic container and cooled and solidified (a backfill method); and a method in which a cosmetic body formed separately by a mold is inserted into the center plate portion of the cosmetic container (an insertion method).

[0004] In addition, another method is a method in which the center plate and the cosmetic container are separate bodies, which is called a two-body center plate method. In the manufacture of stick-shaped cosmetics using a cosmetic container of the two-body center plate method, the following method is used: in a state where only the center plate is mounted on a mold of the cosmetic body, the material of the cosmetic body softened or liquefied by heating is filled, and after cooling and solidifying, the cosmetic body with the center plate is inserted into the cosmetic container.

[0005] The two-body center plate type cosmetic container has the following advantages, because only the cosmetic main body and the center plate are taken out: when a bad situation occurs, not only can the main body of the cosmetic container be reused in a clean state, but also the discarded parts are only small parts such as the center plate. In addition, because the cosmetic main body is solidified in the center plate, it is difficult for the cosmetic main body to fall off, and it has the advantage of being able to cope with soft cosmetic main bodies.

[0031] Modes for carrying out the invention

[0032] Below, based on Figures 1 to 10 Embodiments of the present invention will be described.

[0033] [Stick-shaped cosmetics manufacturing device]

[0034] The stick cosmetics manufacturing device of this embodiment is a device for manufacturing stick cosmetics 1 such as stick lipstick, stick lip gloss, and stick foundation. The stick cosmetics 1 manufactured by the stick cosmetics manufacturing device of this embodiment includes a stick-shaped cosmetics body 2; a middle plate 3 integrated with the base of the cosmetics body 2; and a cosmetics container 4 that accommodates and holds the cosmetics body 2 via the middle plate 3.

[0035] The cosmetic container 4 is a two-body center plate type in which the center plate 3 and the cosmetic container 4 are separated. When manufacturing the stick-shaped cosmetic 1, the following manufacturing method is applied: with only the center plate 3 installed on the mold of the cosmetic body 2 (for example, the rubber mold 5 described later), the material of the cosmetic body 2 softened or liquefied by heating is filled, and after cooling and solidifying, the cosmetic body 2 with the center plate 3 is inserted into the cosmetic container 4.

[0036] The rod-shaped cosmetic manufacturing device of this embodiment uses a first holding member 6 and a second holding member 7, and is equipped with a middle plate installation component for mounting the middle plate 3 on the rubber mold 5; a filling component for filling the material of the cosmetic body 2 softened or liquefied by heating into the middle plate 3 and the rubber mold 5; a cooling component for cooling and solidifying the material of the cosmetic body 2 filled in the middle plate 3 and the rubber mold 5; a second holding member removal component for removing the second holding member 7 from the middle plate 3 using the first opening and closing claws 21 and the second opening and closing claws 22; a movement restriction component for restricting the movement of the middle plate 3 toward the rubber mold 5 side using the third opening and closing claws 23; an embedding component for inserting the middle plate 3 integrated with the solidified cosmetic body 2 into the cosmetic container 4 for embedding; an expansion component for expanding the rubber mold 5 using the vacuum chamber 24; and a removal component for removing the cosmetic body 2 held in the cosmetic container 4 by the middle plate 3 from the rubber mold 5.

[0037] In addition, each of the above-mentioned components is a functional component realized by cooperation of various devices constituting the stick-shaped cosmetic manufacturing device, a control unit that controls the various devices, and a program stored in the control unit, etc. For well-known devices among the various devices constituting the stick-shaped cosmetic manufacturing device, illustration and detailed description may be omitted.

[0038] like Figure 1 As shown, the center plate 3 is a generally cylindrical resin member as a whole, and a hollow portion 3a filled with the material of the cosmetic body 2 softened or liquefied by heating is formed on the inner circumference, a first step portion 3b positioned relative to the second holding member 7 and a second step portion 3c whose movement is restricted by the third opening and closing claw 23 are formed on the outer circumference, a mounting portion 3d mounted on the rubber mold 5 in a crimping manner is formed on one end side in the barrel direction, and an embedding portion 3e embedded in the cosmetic container 4 in a snap-fitting manner is formed on the other end side in the barrel direction. In addition, the mounting portion 3d may be mounted on the rubber mold 5 in an embedding manner.

[0039] like Figure 2 As shown, the rubber mold 5 has a cylindrical shape with one end side in the barrel direction closed, and is formed of an elastically deformable member such as silicone. A hollow portion 5a is formed on the inner circumference of the rubber mold 5 to be filled with the material of the cosmetic body 2 softened or liquefied by heating, and an opening portion 5b is formed on the other end side in the barrel direction to which the mounting portion 3d of the middle plate 3 is mounted in a crimping manner, and a flange portion 5c is formed to extend from the peripheral edge of the opening portion 5b in the outer diameter direction. Alternatively, the mounting portion 3d of the middle plate 3 may be mounted in a fitting manner in the opening portion 5b.

[0040] like Figure 2As shown, the first holding member 6 is a member for holding the rubber mold 5, and has a cylindrical or ring shape. A mounting hole 6a for mounting the rubber mold 5 in an interlaced manner and a stopper 6b for engaging with the flange portion 5c of the rubber mold 5 to restrict the rubber mold 5 from falling off at one end side in the cylinder direction are formed on the inner circumference side of the first holding member 6, an engaging groove 6c for engaging with the first opening and closing claw 21 is formed on the outer circumference side, and a contact surface 6d for contacting with the second holding member 7 and a magnet 6e embedded in the contact surface 6d are provided on the other end side in the cylinder direction.

[0041] like Figure 1 and Figure 2 As shown, the second holding member 7 is a member for holding the middle disk 3, and has a cylindrical or annular shape. The second holding member 7 has a mounting hole 7a for mounting the middle disk 3 in an embedded state and a stepped positioning portion 7b for engaging with the first step portion 3b of the middle disk 3 to position the middle disk 3 formed on the inner peripheral side, an engaging groove 7c for engaging with the second opening and closing claw 22 formed on the outer peripheral side, and an embedded portion 7d embedded in the first holding member 6, a contact surface 7e for contacting with the contact surface 6d of the first holding member 6, and a magnet 7f embedded in the contact surface 7e provided on one end side in the cylindrical direction.

[0042] like Figure 1 and Figure 2 As shown, the middle disc installation assembly installs the middle disc 3 on the rubber mold 5 by fixing the first holding member 6 holding the rubber mold 5 and the second holding member 7 holding the middle disc 3 to each other.

[0043] If specifically described, the middle disk installation components, such as Figure 1 As shown, the middle plate 3 is inserted into the mounting hole 7a of the second holding member 7 from one end side in the cylindrical direction, and after the first step portion 3b of the middle plate 3 is engaged with the positioning portion 7b of the second holding member 7, as shown in FIG. Figure 2 As shown, the second holding member 7 holding the middle disk 3 is placed on the first holding member 6 holding the rubber mold 5, and the embedding portion 7d of the second holding member 7 is embedded in the first holding member 6. As a result, the abutting surfaces 6d and 7e of the two holding members 6 and 7 are in abutment with each other in a state where they are positioned relative to each other, and they are fixed to each other by the magnetic force of the magnets 6e and 7f. Along with this, the middle disk 3 is mounted on the rubber mold 5 by pressing the mounting portion 3d against the periphery of the opening portion 5b of the rubber mold 5, and the mounting state is reliably maintained by the two holding members 6 and 7. In addition, the insertion of the middle disk 3 relative to the second holding member 7 and the placement of the second holding member 7 relative to the first holding member 6 are performed using a known device.

[0044] like Figure 3As shown, the filling unit fills the material of the cosmetic body 2 softened or liquefied by heating into the hollow portion 3a of the middle plate 3 and the hollow portion 5a of the rubber mold 5 from the opening on the other end side of the middle plate 3. The device for heating the material of the cosmetic body 2 and the device for filling only an appropriate amount of the material of the cosmetic body 2 softened or liquefied by heating into the middle plate 3 and the rubber mold 5 are well-known devices.

[0045] like Figure 4 As shown, the cooling unit cools and solidifies the material of the cosmetic body 2 filled in the middle plate 3 and the rubber mold 5. For example, by using a known air-cooling cooling device, cooling air is supplied for a predetermined time to cool the material of the cosmetic body 2 to a predetermined temperature for solidification. When the material of the cosmetic body 2 is solidified, the middle plate 3 and the cosmetic body 2 are integrated.

[0046] like Figure 5 As shown in the figure, the second holding member removal assembly uses the first opening and closing claw 21 and the second opening and closing claw 22 to remove the second holding member 7 from the middle plate 3. The first opening and closing claw 21 on one side is engaged with the engagement groove 6c of the first holding member 6 by the closing action of the claw part, thereby restricting the movement of the first holding member 6 in the cylindrical direction. The second opening and closing claw 22 on the other side is engaged with the engagement groove 7c of the second holding member 7 by the closing action of the claw part, and then moves to the other side in the cylindrical direction, thereby separating the second holding member 7 from the middle plate 3 and the first holding member 6.

[0047] like Figure 6 As shown, the movement limiting assembly uses the third opening and closing claw 23 to limit the movement of the center plate 3 toward the rubber mold 5. The third opening and closing claw 23 is engaged with the second step portion 3c of the center plate 3 by sliding in the cylinder direction and closing the claw portion, thereby limiting the movement of the center plate 3 toward the rubber mold 5.

[0048] like Figure 7 As shown, the inserting assembly inserts the middle plate 3 integrated with the solidified cosmetic main body 2 into the cosmetic container 4 for inserting. For example, the cosmetic container 4 is held downwardly by a known holding device, and the cosmetic container 4 is slid downward to insert the middle plate 3 into the cosmetic container 4. At this time, a force required for inserting the inserting portion 3e into the cosmetic container 4 is applied to the middle plate 3, but the movement of the middle plate 3 toward the rubber mold 5 is restricted by the third opening and closing claws 23, so the rubber mold 5 is prevented from being deformed and the middle plate 3 is reliably inserted into the cosmetic container 4.

[0049] like Figure 8As shown, the expansion assembly uses a vacuum chamber 24 to expand the rubber mold 5. The vacuum chamber 24 is configured as follows: in addition to the vacuum chamber 24 main body that airtightly covers the periphery of the rubber mold 5, it is also provided with a suction pump (not shown) that sucks the air in the vacuum chamber 24 through the suction hole 25 to reduce the external pressure of the rubber mold 5. The rubber mold 5 expands due to the relative increase in the internal pressure accompanying the reduction in external pressure, and the inner peripheral surface is separated from the surface of the cosmetic body 2.

[0050] like Fig. 9 and Fig.10 As shown, after the removal assembly removes the third opening and closing claws 23 from the middle plate 3, the cosmetic body 2 held in the cosmetic container 4 via the middle plate 3 is removed from the rubber mold 5. For example, the cosmetic container 4 is slid upward by the above-mentioned holding device. At this time, the rubber mold 5 is maintained in an expanded state by the vacuum chamber 24, so that no adverse conditions such as friction on the surface of the cosmetic body 2 are generated.

[0051] [Method for producing stick-shaped cosmetics]

[0052] Next, refer to Figures 1 to 10 A method for producing a stick-shaped cosmetic using the stick-shaped cosmetic manufacturing apparatus of the present embodiment will be described. In addition, descriptions of parts overlapping with the description of the stick-shaped cosmetic manufacturing apparatus may be omitted.

[0053] The method for producing a stick-shaped cosmetic according to the present embodiment includes 10 steps.

[0054] like Figure 1 As shown, in the first step, the center plate 3 is inserted into the mounting hole 7a of the second holding member 7 from one end side in the cylindrical direction.

[0055] like Figure 2 As shown, in the second step (middle plate mounting step), the middle plate 3 is mounted on the rubber mold 5 by fixing the second holding member 7 holding the middle plate 3 to the first holding member 6 holding the rubber mold 5. The holding members 6 and 7 are fixed to each other by the magnetic force of the magnets 6e and 7f, and the mounting state of the middle plate 3 relative to the rubber mold 5 is reliably maintained.

[0056] like Figure 3 As shown, in the third step (filling step), the material of the cosmetic body 2 softened or liquefied by heating is filled into the hollow portion 3 a of the center plate 3 and the hollow portion 5 a of the rubber mold 5 .

[0057] like Figure 4 As shown, in the fourth step (cooling step), the material of the cosmetic main body 2 filled in the center plate 3 and the rubber mold 5 is cooled and solidified. Thus, the center plate 3 and the cosmetic main body 2 are integrated.

[0058] like Figure 5 As shown, in the fifth step (second holding member removing step), the second holding member 7 is removed from the middle plate 3 using the first opening and closing claws 21 and the second opening and closing claws 22 .

[0059] like Figure 6 As shown, in the sixth step (movement restriction step), the third opening and closing claws 23 are used to restrict the movement of the center plate 3 toward the rubber mold 5 side.

[0060] like Figure 7 As shown, in the seventh step (fitting step), the middle plate 3 integrated with the solidified cosmetic main body 2 is inserted into the cosmetic container 4 for fitting. At this time, the middle plate 3 is subjected to the force required for fitting from the cosmetic container 4, but the movement of the middle plate 3 toward the rubber mold 5 is restricted by the third opening and closing claws 23, so the rubber mold 5 is prevented from being deformed and is reliably fitted into the cosmetic container 4.

[0061] like Figure 8 As shown, in the eighth step (expansion step), the rubber mold 5 is expanded using the vacuum chamber 24 .

[0062] like Fig. 9 As shown, in the ninth step, the third opening and closing claws 23 are removed from the middle plate 3 .

[0063] like Fig.10 As shown, in the tenth step (removal step), the cosmetic main body 2 held in the cosmetic container 4 via the middle plate 3 is removed from the rubber mold 5 .

[0064] According to the present embodiment configured as described above, the present invention is a manufacturing device and a manufacturing method for a stick-shaped cosmetic 1, wherein the stick-shaped cosmetic 1 includes a stick-shaped cosmetic body 2; a middle plate 3 integrated with the base of the cosmetic body 2; and a cosmetic container 4 that accommodates and holds the cosmetic body 2 via the middle plate 3, wherein the middle plate 3 is mounted on the rubber mold 5 by fixing a first holding member 6 that holds the rubber mold 5 and a second holding member 7 that holds the middle plate 3 to each other, the material of the cosmetic body 2 softened or liquefied by heating is filled into the middle plate 3 and the rubber mold 5, the material of the cosmetic body 2 filled into the middle plate 3 and the rubber mold 5 is cooled and solidified, the second holding member 7 is removed from the middle plate 3, the middle plate 3 integrated with the solidified cosmetic body 2 is inserted into the cosmetic container 4 while the middle plate 3 is moved toward the rubber mold 5, and the cosmetic body 2 held in the cosmetic container 4 via the middle plate 3 is taken out from the rubber mold 5 while the rubber mold 5 is expanded, thereby manufacturing the stick-shaped cosmetic 1.

[0065] According to such a manufacturing device and manufacturing method, since the rubber mold 5 and the middle plate 3 are held separately and the holding members 6 and 7 are fixed to each other, the rubber mold 5 and the middle plate 3 can be reliably fixed. In addition, when the cosmetic body 2 that is integrated with the middle plate 3 after cooling and solidification is inserted into the cosmetic container, since the movement of the middle plate 3 toward the rubber mold 5 is restricted, the rubber mold 5 can be prevented from being deformed and inserted reliably. As a result, the stick-shaped cosmetic 1 using the two-body middle plate type cosmetic container 4 and the rubber mold 5 can be manufactured, and the advantages of the two-body middle plate type cosmetic container 4 and the rubber mold 5 can be obtained.

[0066] In addition, since the middle plate 3 includes the first step portion 3b for positioning relative to the above-mentioned second retaining member 7; the mounting portion 3d mounted on the rubber mold 5; the hollow portion 3a filled with the material of the cosmetic body 2 softened or liquefied by heating; the second step portion 3c for limiting the movement by the third opening and closing claws 23; and the embedding portion 3e embedded in the cosmetic container 4 in a snap-fitting manner, it is possible to obtain a middle plate 3 that can correspond to the manufacturing device and manufacturing method of this embodiment.

[0067] Furthermore, since the first holding member 6 and the second holding member 7 are fixed to each other by the magnets 6e and 7f, not only the rubber mold 5 and the middle plate 3 can be reliably fixed by magnetic force, but also the fixing and separation of the holding members 6 and 7 can be facilitated.
