Description

  The present invention relates to a cosmetic manufacturing method, a manufacturing system thereof, and a cosmetic.

  Cosmetics comprising an inner container (hereinafter also referred to as a middle dish) containing cosmetics such as lipstick and foundation and an outer container that holds the middle dish are widely known. Cosmetics in the inner dish are often formed into various three-dimensional shapes for the purpose of decoration or the like (see, for example, Patent Document 1 and Patent Document 2).

  Conventionally, in order to form a cosmetic material having such a predetermined three-dimensional shape, a so-called hot back method has been employed. That is, two holes (a filling hole and an air hole) are provided in advance on the bottom of the inner plate, and the inner plate is molded on the inside of the inner plate with respect to a mold capable of taking a desired three-dimensional shape. Put it on the surface. Filling the inner space surrounded by the mold and the inner surface of the inner dish with the cosmetic material that has been melted by heating from the filling hole of the inner dish, solidifying the cosmetic material, and then removing the mold to remove the inner dish. A cosmetic product having a three-dimensional shape corresponding to the mold surface is obtained.

  Another conventional forming method is as shown in FIG. A frame 53 is attached to a mold 55 having a mold surface 55a that can mold a desired three-dimensional shape (see FIG. 8A). The internal space surrounded by the mold surface 55a and the frame 53 is filled with the cosmetic 6 in a molten state (see FIG. 8B). After the filled cosmetic 6 is solidified, the mold 55 is removed, and a metal pan 57 is mounted on the back side (see FIG. 8C). The metal pan 57 includes a hole 57 a that can be engaged with a protrusion 53 a provided on the frame 53, and an edge 57 b that can contact the edge 53 b of the frame 53. Is attached with a double-sided tape 57c with release paper. Therefore, when the metal tray 57 is attached to the frame 53, the release paper of the double-sided tape 57c is first peeled off, the hole 57a of the metal plate 57 is engaged with the protrusion 53a of the frame 53, and then the edge of the frame 53 53b and the edge 57b of the metal plate 57 are brought into close contact with each other and fixed by a double-sided tape 57c. Thereby, the cosmetics 51 hold | maintained with the frame 53 and the metal plate 57 are obtained (refer FIG.8 (d)).

  Moreover, the invention described in Patent Document 1 is a method for injecting molten cosmetic material into a cavity formed by a rubber mold and a ring-shaped mold, removing the mold after the cosmetic is solidified, and The three-dimensionally shaped cosmetic was held in the middle dish by inserting the middle dish into a part (the part to be loaded) and heating it from the outside of the bottom of the middle dish to weld the cosmetic to the inside of the middle dish bottom. A method for obtaining a cosmetic product is disclosed.

  In the invention described in Patent Document 2, a cylindrical holder is fitted into an elastic mold, and the enclosed space surrounded by the surface of the elastic mold and the inner peripheral surface of the holder is brought into a fluid state by heating. After filling with cosmetics and closing the opening of the holder with a disk-shaped lid, cooling to solidify the fluid cosmetics, and then removing the elastic mold, it is molded in three dimensions Disclosed is a method for obtaining cosmetics in which cosmetics are held on a holder and a lid.

  However, according to the conventional hot-back molding method, since the filling hole is small, it is extremely difficult to completely spread the cosmetic material to every corner of the inner space surrounded by the mold and the inner surface of the inner dish. . In addition, it is extremely difficult to adjust the filling speed of the cosmetic, the size of the holes, and the positional relationship for allowing the air to escape, taking into account that the internal air is released from the air holes. Furthermore, according to the molding method by hot back, it is extremely difficult to fill two or more kinds of cosmetics having different colors and the like into each desired part.

  Further, in the case of the method shown in FIG. 8, when the metal plate 57 is attached to the frame 53, a work process is required in which the release paper of the double-sided tape 57c attached to the metal plate 57 is manually peeled off each time. This involved complicated and inefficient work.

  Moreover, when the invention described in Patent Document 1 is used for welding cosmetics that are heated from the bottom outer side of the inner dish and solidified on the inner side of the inner dish bottom, if the heating is too much, the cosmetics are excessively melted or the heating is insufficient. Since the cosmetic does not fuse inside the inner dish, the heating conditions for fusing the cosmetic in the inner dish are extremely difficult.

  In addition, the invention described in Patent Document 2 is such that a cosmetic material in a fluid state is filled inside an elastic-type and cylindrical holder and closed with a lid. Not disclosed. Therefore, if adhesion between the holder and the lid is not performed, there is a problem that the oily component flows out between the holder and the lid due to a capillary phenomenon even after the cosmetic is solidified.

  Further, generally, cosmetics in a fluidized state due to heating contract when cooled and solidified, so it is necessary to fill more than the necessary volume in consideration of such volume change due to temperature. Since the invention described in 2 is closed with the lid before the filled cosmetic is solidified, the fluid cosmetic may overflow from between the holder and the lid. In particular, since the lid is provided with an annular protrusion that fits to the inner peripheral surface of the opening of the holder, at least when the lid is brought into contact with the holder opening, The volume of cosmetics will overflow. Therefore, a work process such as wiping off the overflowing cosmetic is required.

  Further, since the lid is closed with the lid before the filled cosmetic is solidified, it is confirmed whether the cosmetic is firmly filled with respect to the elastic mold after the lid is covered with the lid and the cosmetic is solidified. It becomes possible for the first time at the stage of removing. At that time, if the filling was poor, both the holder and the lid were to be discarded, which was costly.

  Accordingly, an object of the present invention is to provide a cosmetic manufacturing method, a manufacturing system thereof, and a cosmetic that can improve the degree of freedom of design and can be manufactured simply and inexpensively with a highly decorative design. There is.

  In order to achieve the above-described object, the cosmetic manufacturing method of the present invention has a first closing member attached to the first opening side of the thermoplastic resin-made surrounding member, and the makeup is made from the second opening of the surrounding member.

It is characterized by having the said adhesion process after solidifying.

  Further, in the cosmetic manufacturing method of the present invention, the surrounding member is formed in an annular shape, and is formed in a direction perpendicular to the first protrusion, the first protrusion being formed along the circumferential direction of the inner peripheral surface thereof. One or more second protrusions are formed.

  Further, in the cosmetic production method of the present invention, in the filling step, the cosmetic to be filled is an oily solid cosmetic made into a fluid state by heating, and the bonding step is performed by ultrasonic welding. A member is adhered to the surrounding member.

  Further, in the cosmetic production method of the present invention, in the filling step, the cosmetic to be filled is a slurry obtained by adding a predetermined solvent to a powder cosmetic, and is filled in the filling step after the filling step. It has a solidification process which removes and solidifies at least a part of the solvent of the slurry, and the adhesion process makes the 2nd closure member adhere to the surrounding member by high frequency welding or heat welding.

FIG. 1 is a schematic cross-sectional view illustrating a cosmetic manufacturing method according to an embodiment of the present invention, FIG. 2 is a schematic diagram illustrating a cosmetic manufacturing system according to an embodiment of the present invention, and FIG. 3 is an embodiment of the present invention. 4 is a schematic cross-sectional view showing a cosmetic surrounding member according to an embodiment of the present invention, and FIG. 5 is a schematic cross-sectional view showing a holder according to the embodiment of the present invention. It is.

[Filling process / Filling equipment]
As shown in FIGS. 1 (a) and 1 (b) and FIG. 2 (a), a mold 5 (first closing member) is attached to the first opening 3b side of the surrounding member 3 made of thermoplastic resin. The cosmetic 6 is filled into the inside of the surrounding member 3 from the second opening 3c of the member 3. The cosmetic 6 according to the present embodiment is an oily solid cosmetic, and examples thereof include various solid makeup that can maintain the shape at room temperature, such as lipstick, lip gloss, lip balm, concealer, foundation, eye color, and cheek color. Fees are included.

  The mold 5 is a closing member (first closing member) that temporarily closes the first opening 3 b side of the surrounding member 3. The material of the mold 5 used in the present embodiment is not particularly limited, but the mold 5 can be bent so that it can be easily released and a desired shape can be beautifully formed in the formation of the oily solid cosmetic 1. It is preferable to use an elastic mold made of an elastic material (for example, silicon resin, rubber).

  On the surface 5a of the mold 5, for example, roses, characters such as animals, abstract three-dimensional shapes, manufacturer's logos, product names, and the like are provided with convex portions and / or concave portions that can mold a desired three-dimensional shape. Is formed. That is, the convex part and / or the concave part of the surface 5a (mold surface) of the mold 5 correspond to a three-dimensional shape desired as the surface design of the cosmetic 6 after molding (the surface 6a which is a cosmetic molding surface). Further, the convex part and / or the concave part of the surface 5a of the mold 5 can be molded so that the surface of the cosmetic 6 after molding has a three-dimensional shape protruding from the first opening 3b of the surrounding member 3. May be configured. Further, according to the example shown in FIG. 1, the edge portion 5 b of the surface 5 a of the mold 5 has a shape protruding so as to be able to come into contact with the inner peripheral surface 3 d of the surrounding member 3.

  As another configuration example, the mold 5 is provided with a grip portion 5c that abuts on the outer peripheral surface 3e of the surrounding member 3 and can grip the surrounding member 3 from the outer peripheral surface 3e side, as shown in FIG. May be.

  The surrounding member 3 includes an arbitrary outer peripheral shape configured to surround a predetermined range at a constant height. In the present embodiment, the surrounding member 3 is a member that surrounds and holds the solidified cosmetic 6 with the inner peripheral surface 3d. The surrounding member in the present invention may be, for example, a flat frame-shaped member that can be accommodated in a flat compact shape, or a cylindrical member that can be accommodated in a feeding container such as a stick-shaped lipstick. However, in the present embodiment, the former will be described as an example. The surrounding member 3 includes a first opening 3b that is closed when the mold 5 (first closing member) is attached and a second opening that is closed when a closing member 4 (second closing member) described later is bonded. 3c. Eventually, the surrounding member 3 constitutes the container 2 (for example, an inner dish) together with the closing member 4 bonded to the second opening 3c side.

  The surrounding member 3 is provided with positioning means for adhesion to the closing member 4 on the second opening 3c side. In the present embodiment, as shown in FIG. 1A and the like, a recess 3a is provided at the end of the outer peripheral surface 3e of the surrounding member 3 on the second opening 3c side, and a projection 4b of the closing member 4 described later. And can be fitted. Thus, since the surrounding member 3 is provided with the recess 3a at the end of the outer peripheral surface 3e on the second opening 3c side, the filling member 3 is filled with the cosmetic material 6 and solidified after the closing member 4 described later. Even if the protrusion 4 b is fitted, the protrusion 4 b of the closing member 4 does not enter the inner region of the surrounding member 3, and there is no influence such as extruding the cosmetic 6 already molded inside the surrounding member 3. In addition, providing the positioning means provided in the surrounding member 3 and the closing member 4 is arbitrary, and is not an essential requirement of the present invention.

  The surrounding member 3 is preferably made of a thermoplastic resin so as to be able to be bonded to the closing member 4 described later by ultrasonic welding, high-frequency welding, thermal welding, or the like. However, the surrounding member 3 and the closing member 4 may use other bonding means (for example, bonding with an adhesive or the like), and the material of the surrounding member is not limited to the thermoplastic resin in the present invention.

  The inner peripheral surface 3d of the surrounding member 3 may be configured to stand vertically from the first opening 3b toward the second opening 3c, as shown in FIG. As shown to (b), it is good also as a structure which provides the protrusion 3f in a part of inner peripheral surface 3d. Moreover, as shown in FIG.4 (c), it is good also as a structure which makes the internal peripheral surface 3d into the taper surface where the 2nd opening part 3c becomes wider than the 1st opening part 3b. 4B and 4C, when the mold 5 is removed, the cosmetic 6 solidified by the solidification process (solidification device) as described later remains in the surrounding member 3, and the cosmetic 6 is more prevented from falling off from the surrounding member 3.

  Moreover, as shown in FIG.4 (d), in the surrounding member 3 formed in the annular | circular shape as a whole, the protrusion (horizontal rib. 1st protrusion) formed along the circumferential direction of the internal peripheral surface 3d. It is good also as a structure which has 3g and the protrusion (vertical rib. 2nd protrusion) 3g formed 1 or more in the orthogonal | vertical direction with 3f. This prevents the cosmetic 6 from falling off from the surrounding member 3 even when the cosmetic 6 filled in the filling step (filling device) described later is solidified, and also prevents the cosmetic 6 from falling inside the surrounding member 3. Rotation is also prevented. The heights of the protrusion 3f and the protrusion 3g from the inner peripheral surface 3d are set according to the shrinkage rate when the cosmetic 6 is solidified, and as an example, the solidified cosmetic 6 and the protrusion 3f. It is preferable to set so that the protrusion 3g engages with 0.1 mm or more. In addition, in order to prevent the cosmetic 6 from rotating in the surrounding member 3, the surrounding member 3 may be formed in an elliptical shape or a polygonal shape instead of or in addition to the protruding portion 3g.

  The surrounding member 3 is attached to the mold 5 by inserting the edge 5b of the surface 5a of the mold 5 into the first opening 3b of the surrounding member 3 while contacting the inner peripheral surface 3d (FIG. 1). (Refer to (a)) and supply to the supply point P2 on the upstream side of the conveyor 12 of the filling device 11 (FIG. 2A). The conveyor 12 is driven by driving means (not shown) according to an arbitrary driving condition set in advance.

  Next, cosmetics 6 are filled inside the surrounding member 3 attached to the mold 5 (see FIG. 1B). The space 6 surrounded by the surface 5a of the mold 5 and the inner peripheral surface 3d of the surrounding member 3 is filled with the cosmetic 6 supplied from the nozzle 13a from the second opening 3c side of the surrounding member 3. More specifically, cosmetic 6 (bulk) as a fluid oily solid cosmetic previously melted by heating at a predetermined temperature is placed in hopper 13 of filling device 11 through a process such as deaeration, The surrounding member in which the cosmetic 6 flows from the nozzle 13a by a certain amount (that is, the amount corresponding to the space volume surrounded by the surface 5a of the mold 5 and the inner peripheral surface 3d of the surrounding member 3) by the conveyor 12. 3 is filled into the attached mold 5 (see FIG. 2A). In addition, in order to maintain the fluid state of the cosmetic 6, the hopper 13 and the nozzle 13a can be heated at a predetermined temperature.

  The cosmetic 6 filled in the mold 5 and the surrounding member 3 is reheated (reheated) in the heating unit 14 of the filling device 11 shown in FIG. Thereby, the unevenness | corrugation of the surface of the cosmetics 6 is lose | eliminated, and the smooth surface 6b (refer FIG.1 (c)) can be obtained. The heating unit 14 may use a heating wire as an example. It is preferable to set the reheating time short so that the surrounding member 3 made of thermoplastic resin does not melt. In addition, implementation of a reheating (reheat) process is arbitrary.

  As described above, since the cosmetic 6 in a fluid state is filled from the second opening 3c of the enclosing member 3 that is largely opened, the cosmetic 6 can be easily distributed to every corner of the mold 5, The quality can be improved and the yield can be improved.

  In addition, it becomes possible to adopt a design and shape that have been difficult to fill by hot back in a conventional middle dish, and the degree of freedom in design can be improved. For example, according to the present invention, it is also easy to form a multicolor cosmetic by filling two or more kinds of cosmetics having different colors and the like into a desired part, and is suitable for a small and thin container 2 (medium dish). Even in the case of cosmetic molding, there is an advantage that the degree of freedom of design increases. In addition, as a method of molding a multicolor cosmetic, (1) before filling the cosmetic 6, a partition (not shown) is set on the surrounding member 3 and the mold 5 to fill the first cosmetic. After solidifying and solidifying, the partition is removed, and the second cosmetic is filled and solidified in the unfilled portion, or (2) only the part of the mold 5 is filled with the first cosmetic and solidified. After that, a method of filling and solidifying the second cosmetic material from above can be used.

[Solidification process / solidification equipment]
As shown in FIGS. 1C and 2A, the cosmetic 6 filled in the filling step (filling device) is solidified.

  The cosmetic 6 (see FIG. 1C) filled in the mold 5 and the surrounding member 3 is moved to the cooling unit 15 by the conveyor 12 of the filling device 11 shown in FIG. Solidified.

  As shown in FIG. 2A, the cooling unit 15 as the solidification device in the present embodiment includes an arbitrary cooling unit, and the cooling target object moved by the conveyor 12 is subjected to a cooling process. . In order to improve the cooling effect by the cooling unit 15, it is preferable to cover the cooling region by the cooling unit 15 with the cover 16.

  In the present embodiment, the example in which the cooling unit 15 as the cooling device is configured integrally with the filling device 11 has been described, but the filling device 11 and the cooling unit 15 as the cooling device are configured separately. Needless to say. Moreover, the solidification process (solidification apparatus) in this embodiment should just be what solidifies the cosmetics 6 with which the mold 5 and the surrounding member 3 were filled, and is not limited to the process of performing a cooling process as mentioned above. For example, it may be a cooling process in which the object to be cooled is allowed to cool to room temperature, and is not particularly limited.

  The cosmetic 6 solidified by the cooling unit 15 is carried out together with the mold 5 and the surrounding member 3 at the collection point P3 of the conveyor 12 shown in FIG.

  As shown in FIG. 1 (d), after the mold 5 and the surrounding member 3 filled and solidified with the cosmetic material 6 are unloaded from the filling device 11, the surrounding member 3 and the cosmetic material 6 are removed from the surface 5 a of the mold 5. Remove. Thereby, the surface 6a of the three-dimensional shape shape | molded corresponding to the convex part and / or the recessed part of the surface 5a of the mold 5 appears in the cosmetics 6 by the side of the 1st opening part 3b of the surrounding member 3. FIG. On the other hand, on the second opening 3c side of the surrounding member 3, the cosmetic 6 having a smooth surface 6b that is flush with the end of the surrounding member 3 on the second opening 3c side appears.

  In the case where the surrounding member 3 in which the cosmetic 6 is surrounded is directly attached to an outer container or the like (not shown) to make a cosmetic product, the user can take the surface 6a side of the cosmetic 6 with the applicator and use it little by little. Furthermore, since the cosmetic 6 is pushed out from the second opening 3c side to the inside of the outer container, it is necessary to close the second opening 3c side of the surrounding member 3. Then, the adhesion process which adhere | attaches the closure member 4 with respect to the surrounding member 3 is implemented continuously.

  In addition, after solidification of the filled cosmetic 6, before the adhesion process described later, it can be confirmed whether the cosmetic 6 is accurately filled into the mold 5 and formed. In such a case, only the surrounding member 3 filled with the cosmetic material 6 has to be discarded, and the closing member 4 before being used for closing can be saved, so that the cost can be reduced as a whole.

[Adhesion process and equipment]
As shown in FIGS. 1D, 1E, and 2B, a thermoplastic resin that closes the second opening 3c of the surrounding member 3 after the cosmetic 6 is solidified by a solidification step (solidification device). The made closure member 4 is bonded to the surrounding member 3. In the bonding step (bonding device), the closing member 4 is bonded to the end of the surrounding member 3 on the second opening 3c side. More preferably, the bonding step (bonding device) is to bond the closing member 4 to the entire circumference of the end portion of the surrounding member 3 on the second opening side 3c.

  The closing member 4 which is the second closing member in the present embodiment has a smooth portion 4a for closing the second opening 3c of the surrounding member 3, and has a shape corresponding to the outer peripheral shape of the surrounding member 3. The shape is not particularly limited as long as the second opening 3c of the surrounding member 3 can be closed. Finally, the closing member 4 constitutes the container 2 together with the surrounding member 3 (see FIG. 1 (f)).

  The closing member 4 is provided with positioning means for bonding with the second opening 3c of the surrounding member 3. In this embodiment, as shown in FIG.1 (d), the protrusion 4b is provided in the peripheral part of the closure member 4, and it is comprised so that fitting with the recessed part 3a of the surrounding member 3 is possible.

  The closing member 4 is preferably made of a thermoplastic resin in order to enable adhesion with the surrounding member 3 by ultrasonic welding, high-frequency welding, thermal welding, or the like. However, the surrounding member 3 and the closing member 4 may use other bonding means (for example, bonding with an adhesive or the like), and the material of the closing member 4 is not limited to the thermoplastic resin in the present invention.

  Adhesion of the closing member 4 to the surrounding member 3 is performed using an adhesive device 17 shown in FIG. The bonding apparatus 17 mainly includes a turntable 18 and a bonding machine 19, and the turntable 18 includes four stations 18a to 18d as an example, and each station can be rotated counterclockwise by a driving means (not shown). Has been. Note that the rotation direction of the turntable 18 is not limited to the counterclockwise direction, and may be clockwise, or other transfer means (for example, a conveyor) of the turntable may be employed. Further, in the present embodiment, the bonding apparatus 17 including the turntable 18 will be described as an example, but any apparatus including at least the bonding machine 19 may be used.

  The surrounding member 3 is supplied to the station at the position A in FIG. 2B in a state where the closing member 4 is fitted to the second opening 3c side of the surrounding member 3 (see FIG. 1E). ). Similarly, in the station in the position C, the bonding process between the closing member 4 and the surrounding member 3 is performed, and in the station in the position D, the closing member 4 and the surrounding member 3 (container 2 shown in FIG. f) is discharged. Note that the station at position B is used as a standby zone immediately before the welding process.

  Each of the stations 18a to 18d is provided with a holder 22 (see FIG. 5) capable of holding the surrounding member 3 and the closing member 4. When carrying out adhesion between the surrounding member 3 and the closing member 4, it is preferable that the surrounding member 3 and the closing member 4 are held by the holder 22 of each station at the position A shown in FIG. In the present embodiment, the adhesion between the surrounding member 3 and the closing member 4 is performed with the first opening 3b of the surrounding member 3 facing downward, but on the first opening 3b side of the surrounding member 3. The three-dimensional cosmetic material 6 has already been molded, and particularly when the three-dimensional shape protrudes from the surrounding member 3, the three-dimensional shape of the cosmetic material 6 collapses due to contact with other members. This is because it needs to be protected so that there is no. At the same time, alignment for the bonding process by the bonding machine 19 can be realized. In addition, you may make it implement adhesion | attachment with the surrounding member 3 and the obstruction | occlusion member 4 in the state which faced the 1st opening part 3b of the surrounding member 3 upwards.

  As shown in FIG. 5A, the holder 22 includes a support portion 22 a that supports the surrounding member 3, and an accommodation space 22 b that accommodates the three-dimensional cosmetic 6 protruding from the surrounding member 3. The support part 22a should just be the structure which can support the edge part by the side of the 1st opening part 3b of the surrounding member 3, and the holder 22 of this embodiment has provided the step part as an example. The length L from the support portion 22a to the inner bottom portion is set to be longer than the protruding amount of the cosmetic 6 from the three-dimensional shape surrounding member 3. Accordingly, as shown in FIG. 5B, when the surrounding member 3 and the closing member 4 are held by the holder 22 (see FIG. 1E), the three-dimensional shape of the cosmetic 6 protruding from the surrounding member 3 is obtained. Is protected by the accommodation space 22b, and the collapse of the three-dimensional shape due to contact with other members can be prevented.

When the processing flow in the bonding apparatus 17 is shown by paying attention to a certain station, it is as follows.
(1) The surrounding member 3 and the closing member 4 are held by the holder 22 of the station at the position A shown in FIG. 2B (see FIG. 1E).
(2) The turntable 18 rotates, the station moves to the position B, and the preparation before the bonding process is completed.
(3) When the turntable 18 rotates and the station moves to the position C, the bonding machine 19 performs the bonding process on the surrounding member 3 and the closing member 4.
(4) Subsequently, when the turntable 18 is rotated and the station is moved to the position D, the adhered surrounding member 3 and closing member 4 (container 2, see FIG. 1 (f)) are discharged by the discharge means (not shown). It is discharged to the slider 20 and recovered to the recovery tray 21.
(5) The turntable 18 rotates, the station moves to the position A, and the processes from (1) are repeated.

  In the present embodiment, the bonding machine 19 in the bonding apparatus 17 is preferably configured as an ultrasonic welding machine. The ultrasonic welder only needs to have a predetermined configuration such as an oscillator, a vibrator, and a horn, as already known, and a detailed description thereof is omitted.

  According to such an ultrasonic welding machine, the heat generation on the surfaces of the closing member 4 and the surrounding member 3 is very small, and the joining portion P1 between the surrounding member 3 and the closing member 4 made of thermoplastic resin (FIG. 1 (e)). )) Is instantly melted and bonded by frictional heat and pressure applied by ultrasonic vibration. Therefore, as in this embodiment, in the production of the oily solid cosmetic that melts by heating, the surrounding member 3 and the closing member 4 are bonded instantaneously and easily without damaging the molded cosmetic 6.

<Second and Third Embodiments>
2nd, 3rd embodiment of this invention demonstrates the manufacturing method, manufacturing system, and solid powder cosmetics of solid powder cosmetics. In the following description, detailed description of the same configuration / method as in the first embodiment is omitted. The mold 5 does not have to be an elastic mold.

  In the filling step and filling device of the second embodiment, the cosmetic to be filled is a slurry in which a predetermined solvent is added to a powder cosmetic of a predetermined component. In the solidification step and the solidification apparatus, at least a part of the solvent of the filled slurry is removed and solidified. Preferably it is compression molded. In addition, in the bonding process between the surrounding member 3 and the closing member 4, ultrasonic welding with vibration (ultrasonic welding machine) is used so as not to destroy the solid powder cosmetics molded and solidified on the surrounding member 3. First, the closing member 4 is bonded to the surrounding member 3 using high-frequency welding (high-frequency welding machine).

  In the filling step and filling device of the third embodiment, the cosmetic to be filled is a powder cosmetic with a predetermined component. Further, in the solidification step and the solidification apparatus, the filled powder cosmetic is pressurized and solidified by compression formation. In addition, in the bonding process between the surrounding member 3 and the closing member 4, ultrasonic welding with vibration (ultrasonic welding machine) is used so as not to destroy the solid powder cosmetics molded and solidified on the surrounding member 3. First, the closing member 4 is bonded to the surrounding member 3 using high-frequency welding (high-frequency welding machine).

  According to such high-frequency welding, the closing member 4 can internally heat only the portion where the surrounding member 3 is welded (joint portion P1, see FIG. 1E), and can be bonded in a short time. The heat does not affect the parts that are not welded. Further, since solid powder cosmetics are less damaged by heat than oily solid cosmetics, it is also possible to use heat welding (heat welding machine) instead of high frequency welding (high frequency welding machine). As the high-frequency welder or the heat welder, a known configuration may be used, and a detailed description is omitted.

<Fourth embodiment>
In the above embodiment, the case where the cosmetic 6 is finally solidified has been described as an example, but the present invention is not limited thereto. A cosmetic manufacturing method, manufacturing system, and cosmetic according to a fourth embodiment of the present invention will be described with reference to FIG. FIG. 7 is a schematic cross-sectional view illustrating a cosmetic manufacturing method according to a fourth embodiment of the present invention. In the following description, detailed description of the same configuration / method as in the first embodiment is omitted.

  As shown in FIG. 7, a sheet 7 (first closing member) made of, for example, a film or an aluminum sheet is attached to the end of the surrounding member 3 on the first opening 3b side to close the first opening 3b ( FIG. 7 (a)). The sheet 7 is attached to the surrounding member 3 so that the user of the cosmetic 1 can peel off at the start of use, and is attached to the entire periphery of the end portion of the surrounding member 3 on the first opening 3b side. It is preferable to do so. Thereafter, liquid or powdery cosmetic 6 is filled from the second opening 3c side of the surrounding member 3 (see FIGS. 7B and 7C). Subsequently, the closing member 4 (second closing member) that closes the second opening 3c of the surrounding member 3 is bonded to the surrounding member 3 (see FIGS. 7D and 7E). Note that the bonding method may be any of ultrasonic welding, high-frequency welding, thermal welding, and bonding with an adhesive, as in the above embodiment. Thereby, the cosmetic 1 in which the liquid or powdery cosmetic 6 is enclosed in the container 2 including the surrounding member 3 and the closing member 4 can be obtained.

  According to the manufacturing method in which liquid or powdery cosmetic is filled into the containing area from the opening of the container and then the opening of the container is sealed with a sealing material, due to dripping or rising of powder at the time of filling, Cosmetics may adhere to the edge of the opening of the container. When the sealing step is performed in this state, the sealing performance between the container and the sealing material is significantly deteriorated. Therefore, it is desirable to fill the container with cosmetics in a state where the sealing material is sealed in advance in the container. In this case, as a technique for providing a filling port on the side surface or bottom surface of the container and closing the filling port after filling with cosmetics, for example, an engaging portion (under-fit) that can be fitted with a closing member that closes the filling port. (Cut) is formed in a container, heat-sealing of a closing member, or adhesion by a double-sided tape. However, it is necessary to form an engaging portion having irregularities on the container or to secure an adhesion region for adhesion, and there is a problem that the shape of the container is restricted. In this respect, according to the manufacturing method, the manufacturing system, and the cosmetic product according to the present embodiment, the second opening 3c that is the filling port is closed by the closing member 4 after the cosmetic product 6 is filled into the surrounding member 3 to which the sheet 7 is attached in advance. Since bonding is performed by ultrasonic welding or the like, there are few restrictions on the shape of the container, sealing can be performed without gaps, and space can be saved in manufacturing equipment.

  Although the present invention has been described with reference to the above embodiment, the present invention is not limited to the above embodiment, and can be improved or changed within the scope of the purpose of the improvement or the idea of the present invention.
