Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medium dish filled with cosmetics and their production how. 2. Description of the Related Art Conventionally, as a filling material for filling a middle plate, a middle plate formed by erecting a side wall on the outer periphery of a bottom plate is generally used. However, when the fluid having a fluidity is filled in the inner plate and solidified, the cosmetic material shrunk with the solidification may fall out of the inner plate. In order to prevent the cosmetic from falling off, a side wall is erected on the outer periphery of the bottom plate, and a convex portion or a concave portion is provided in the circumferential direction of the inner surface of the middle stage of the side wall, and the cosmetic is locked by the convex portion or the concave portion. It was being adopted. By the way, a conventional filling method, that is, a liquid cosmetic such as oil gel, foundation or red, is filled up to the upper side of the side wall of the above-mentioned two kinds of middle plates, and after cooling and solidifying or evaporating the solvent, In the method of solidifying, as shown in FIG. 7C, since the fluid cosmetic material is in close contact with the side wall of the inner plate to form a thin film portion, the thin film portion of the cosmetic material easily cracks during cooling. generate. In addition, when the cosmetic filled in the middle plate is cooled unevenly, dents and dents (hereinafter, referred to as sink marks) are generated. [0005] In particular, when a middle plate provided with a convex portion or a concave portion in the circumferential direction at the middle of the inner surface of the side wall is used, the cosmetic that is filled above the convex portion or the concave portion and is in close contact with the side wall is:
It is easier to cool than other cosmetics and shrinks rapidly and solidifies. For this reason, cracks and sinks are more easily generated than when an inner plate having no convex portion or concave portion on the inner surface of the side wall is employed. [0006] The cracks and sink marks are not only unsightly in appearance, but also cause the oil content of the cosmetic to accumulate in the cracks and dents and to cause dust to enter, thereby causing the quality of the cosmetic to deteriorate. [0007] As a countermeasure, a method of heating the inner plate before filling with the cosmetic, reheating the surface of the cosmetic after filling with the cosmetic, and gradually cooling by forced cooling or natural cooling, is used. Shrinkage is prevented to prevent cracks and sink marks. [0008] When this method is adopted, an apparatus for performing each step of heating, reheating and slow cooling is required. In addition, since each step of heating, reheating, and slow cooling in the above method requires strict conditioning, a device or personnel for controlling the device is required. [0009] Therefore, while the above method requires a large number of steps and a large cost, it is difficult to solidify the cosmetic without generating cracks or sink marks due to the strict conditions, and the cracks are completely eliminated. It could not be prevented and was not rational. SUMMARY OF THE INVENTION Accordingly, the present invention provides an inexpensive inner plate filling cosmetic which does not cause cracks or sink marks after filling and solidifying a fluid cosmetic, and a simplified inner plate. the technical problem to provide a manufacturing how filling cosmetic. The present invention has the following features to attain the object mentioned above. The medium-filled cosmetic composition of the present invention is a liquid-filled cosmetic medium in which a side wall is erected on the outer periphery of the bottom plate and has a convex portion or a concave portion formed along the circumferential direction of the inner surface of the side wall. After filling up to the protrusions or recesses on the inner surface of the side wall of the inner plate , it is solidified by cooling or melting.

Preferably, the bottom plate is provided with one or more projections to increase the adhesion between the cosmetic and the inner plate and prevent the cosmetic from falling off. [0013] It is preferable that the side wall is erected perpendicularly to the bottom plate, or that the side wall is tapered slightly outward toward the upper side in order to enlarge the filling port of the cosmetic. The bottom plate and the side wall may be formed by joining separately manufactured members, but are preferably integrally formed from the viewpoint of preventing leakage from the joint. A plurality of protrusions or recesses may be provided, for example, one provided on the inner surface of the middle section of the side wall and another provided on the upper section. [0015] The cross-sectional shape of the convex or concave portion is such that, when the cosmetic is filled up to the convex or concave portion, the surface center of the cosmetic has a contact line between the convex or concave portion and the cosmetic due to surface tension. Any shape may be used as long as a bulge can be formed upward. The projections or depressions are preferably formed by projecting or depressing the side walls, but may be formed by increasing or decreasing the thickness of the side walls. The projection may be separately formed and attached to the inner surface of the side wall. As the material of the inner plate, any material such as metal and plastic may be used, but metal, particularly aluminum is preferable. The inner surface of the inner plate is preferably processed with a silicone resin or coated with a silicone resin in order to reduce the wettability between the cosmetic to be filled and the inner surface of the inner plate. [0018] An outer flange-shaped flange for tightly bonding the seal film may be integrally provided around the upper end opening edge of the inner plate body. The method for producing a medium-filled cosmetic according to the present invention comprises:
The side wall is set up on the outer periphery of the plate and

The stopper is located in a state of closing the transfer path in the inner plate conveying device, abuts on the inner plate to stop at the cosmetic filling position, and falls down in the conveying direction after the completion of the cosmetic filling. The cosmetic filling device releases the stop state of the inner plate by retreating, and the cosmetic filling device is configured such that, at the time of filling the cosmetic, the convex portion or the concave portion is closer to the contact line where the cosmetic contacts the cosmetic. Form a bulge upward
You. Various conveyors such as a belt conveyor and a slat conveyor are used as the above-mentioned inner plate conveying device.
It is preferable to use a chain conveyor in that no impact is applied. The stopper is provided as means for stopping the inner plate at the cosmetic filling position, and has, for example, a rectangular parallelepiped shape, and has one end locked so as to rotate in the transport direction of the inner plate and in the opposite direction. The other end is provided rotatably in the transport direction and the reverse direction, and the operation is controlled by an air cylinder or the like. The shape of the stopper may be any shape, such as a rectangular parallelepiped bent into an L-shape or a rectangular shape, as long as the inner plate is stopped. Further, the stopper may be rotated only in one direction by a ratchet mechanism to stop the middle plate and release the stopped state. When a large number of the middle plates are transported, the middle plates are stopped at the cosmetic filling position to prevent the middle plates from being jammed. A circuit breaker may be provided. For example, the cut-off device is provided on an inner plate transfer device, and after one of the inner plates has passed, the breaker descends to a position where it blocks the transfer path, and comes into contact with the transferred inner plate, and Shut off the transport. The inner plate stopped at the cosmetic filling position by the stopper is filled with the cosmetic up to the convex portion or the concave portion on the inner surface of the side wall of the inner plate by the cosmetic filling device in the same manner as in the manufacturing method described above. The cosmetic is filled so that the center of the surface of the cosmetic rises above the contact line. When the filling of the cosmetic is completed, the inner plate is conveyed by the inner plate conveying means. This transfer is started by the release operation of the stopper. At this time, the swelling formed on the surface of the cosmetic filled in the inner plate is not broken. Therefore, the stopper is retracted so as to fall down in the transport direction, and the stopped state of the inner plate is released. Although the inner plate is conveyed to the cosmetic solidifying position and solidified by natural cooling, it may be solidified by forced cooling by a cooling device. After filling the cosmetic into the convex or concave portion provided on the inner surface of the side wall of the inner dish, the cosmetic for filling the inner dish of the present invention is cooled.
By solidifying or evaporating and solidifying the solvent , the cosmetic is uniformly cooled without affecting the cosmetic in the vicinity of the convex portion or the concave portion, and the cosmetic shrinks, and the surface of the cosmetic becomes smooth. Embodiment 1 An embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the inner plate 1 filled with the cosmetic has a circular bottom plate 2 with a side wall 3 erected on the outer periphery thereof, and a convex portion 4 is provided along the circumferential direction of the inner surface of the side wall. I have. The protrusion 4 is formed by projecting the side wall 3 inward. As shown in FIG. 1, the bottom plate 2 is provided with a cross-shaped projection 5 for preventing the solidified cosmetic from falling off, and the upper end of the side wall 3 faces outward along the circumferential direction. Is provided with a flange portion 6 so that a seal film (not shown) is brought into close contact therewith. . The inner plate is integrally formed of aluminum, and is anodized to prevent corrosion. The inner surface of the inner plate is coated with a silicone resin in order to reduce the wettability with the cosmetic to be filled. The inner plate is 50.85 m in diameter of the bottom plate.

Next, an apparatus for producing a cosmetic filled with a middle dish according to the present invention using the above-described middle dish will be described with reference to FIGS. The manufacturing apparatus includes a chain conveyor 7 that transports the inner tray 1, a breaker 8 that shuts off the transport of the inner tray 1, and a first photosensor 1 that detects the passage of the inner tray 1.
1 and a second photo sensor 1 for detecting the presence or absence of the inner plate 1
2 and a cosmetic filling device 9 for filling the inner plate 1 with cosmetics
And a stopper 10 for stopping the inner plate 1 at the cosmetic filling position. The chain conveyor 7 has a slat for carrying a conveyed object mounted on the upper surface thereof, and has a chain endlessly stretched inside. When the chain is driven, the slat moves in the transport direction, and transports the inner plate 1. As shown in FIG. 4, two chain conveyors 7 are arranged in parallel with a gap 13 therebetween to form one transport line. On the chain conveyors 7, 7, a breaker 8 for blocking the transfer of the inner tray 1 is provided so as to be vertically movable. The cut-off device 8 descends to a position where it closes the transport path after one intermediate plate 1 has passed, and comes into contact with the intermediate plate 1 that is being transported to interrupt the transport of the intermediate plate 1. The first side of the transfer line, which is spaced from the installation position of the circuit breaker 8 by approximately one inner plate,
A photo sensor 11 is provided, and detects the inner tray 1 passing on the transport line. From the installation position of the breaker 8 in the transport direction,
The stopper 10 having a shape in which a rectangular parallelepiped is bent in a rectangular shape is provided in the gap 13 of the chain line 7 at an interval where just four of the inner plates 1 enter. The stopper 10 has one end engaged so as to rotate in the direction opposite to the direction in which the inner plate is conveyed, and the other end is provided so as to freely move in a rotatable direction, and is conveyed to the cosmetic filling position. The middle plate 1 is stopped by coming into contact with the middle plate 1 and driven by an air cylinder (not shown) so as to release the stop of the middle plate 1 after the cosmetic is filled. The second photosensor 12 is provided on the side of the cosmetic filling position, and detects the presence of the inner tray 1 conveyed by the chain conveyor 7. Just above the cosmetic filling position, the cosmetic filling device 9 is installed. The cosmetic filling device 9 has a filling nozzle that strokes up and down, and at the time of filling, the filling nozzle descends to fill the cosmetic. After the filling is completed, when the stopper 10 is released and the middle plate 1 is moved, the second photosensor 12 is operated, the breaker 8 is raised, and only one middle plate 1 is moved. The first photosensor 11 and the second photosensor are connected to a controller (not shown), and the breaker 8 and the stopper 10 are controlled by a signal from the controller. The arrows in FIGS. 3 and 4 indicate the transport direction. The method for producing a medium-filled cosmetic according to the present invention will be described by describing the operation of the production apparatus. First, as shown in FIG. 4, the inner tray 1 is placed on the slats at a fixed interval so as to straddle the two chain conveyors 7 so that the center thereof is in the middle of the gap 13. . The driving of the endless chain inside the chain conveyor 7 causes the slats to move in the transport direction, and the inner plate 1 to be transported. The two chain conveyors 7
Are set at the same speed so as to move in the transport direction with the inner plate 1 placed. The pitch of the chain conveyor is 2
0.6 pieces / min, the speed was 50 mm / sec. The first photo sensor 11 detects the middle plate 1 passing through the transport line, and a control unit (not shown) connected to this photo sensor
, The stopper 10 is operated. The stopper 10 provided in the gap 13 of the chain conveyor 7 is located in a state where the other end is rotated in a direction opposite to the conveying direction and closes the conveying path of the inner plate 1 by the operation of the air cylinder. . The conveyed inner plate 1 is the stopper 1
0 and is stopped at the cosmetic filling position.
In addition, the said slat is always driving during filling of cosmetics. When one of the inner plates 1 has passed, the cut-off device 8 descends to a position where it closes the conveying path, and abuts on the inner plate 1 that is conveyed later to interrupt the conveyance. . Further, in a state where the inner plate 1 is stopped at the cosmetic filling position, the second photosensor 12 provided on the side surface of the cosmetic filling position detects the presence of the inner plate 1. As shown in FIG. 3, the inner plate 1 stopped by the stopper 10 at the cosmetic filling position blocks light emitted from the second photosensor 12. Meanwhile, the first
The light emitted from the photo sensor 11 is not blocked. As described above, the cosmetic filling device 9 is operated under the condition that the first photosensor 11 does not detect and the second photosensor 12 detects. The filling nozzle provided in the cosmetic filling device 9 descends from a fixed position so as to fill an appropriate amount of cosmetic, and starts filling with fluid cosmetic. The length of the stroke of the filling nozzle was 53 mm, and the height of the filling nozzle at the time of filling was 17 mm from the transport line. The cosmetic is once filled up to the convex portion 3 on the inner surface of the side wall. Further, as shown in FIG. 5, the surface center A of the cosmetic material is brought into contact line B between the convex portion and the cosmetic by the surface tension. Fill until it rises higher. That is, the filling is performed by adding a slightly larger amount to the filling amount obtained by calculating the volume up to the convex portion 4 of the inner plate 1 in advance. When the filling of the cosmetic is completed, the filling nozzle rises to a fixed position. The cosmetic was filled with 13.04 to 13.06 g at a temperature of 70.8 ° C. at the time of filling the cosmetic using a foundation. When the filling of the cosmetic is completed, an air cylinder for controlling the stopper 10 is operated in response to a signal from a control unit (not shown), and the other end of the stopper 10 is rotated in the conveying direction of the inner plate 1. Then, the stopped state of the inner plate 1 is released. At this time, the stopper 10 is retracted so as to fall down in the transport direction in order to prevent the swelling from being collapsed by applying an impact or vibration to the inner plate 1. The evacuation time was 0.5 seconds. The retracting speed of the stopper 10 is preferably 100 to 50% of the conveyor speed. Thus, the inner tray 1 is transported by the chain conveyor 7 again. Then, the second photosensor 12 is operated, and the circuit breaker 8 rises, passes only one inner plate 1 and shuts down the inner plate 1 that is again conveyed. . The cosmetic filled in the inner plate 8 is cooled by natural cooling or a cooling device. As a result, the cosmetic material shrinks due to a change in volume, evaporation of volatile components, and the like, and the swelling of the central portion A of the surface shown in FIG. Through the above-described steps, the cosmetic for filling the middle plate of the present invention is manufactured. The medium-filled cosmetics manufactured by the method using the above-described apparatus are such that the cosmetics near the convex portions cool faster than other portions and do not rapidly shrink and solidify, and are uniformly cooled and solidified. . As a result, the surface of the cosmetic does not have cracks or sink marks, and a beautifully smooth surface can be obtained.Also, it is possible to prevent the oil and dust of the cosmetic from accumulating on the cracks and sink marks. The deterioration of the quality of the cosmetic caused by the above can be suppressed. Further, since a step such as reheating after filling the cosmetic is not required, no equipment is required for the step. Therefore, it is possible to reduce the cost required for producing the middle plate filling cosmetic, and to provide an inexpensive middle plate filling cosmetic. Embodiment 2 Instead of the inner plate used in Embodiment 1, a side wall is erected on the outer periphery of the bottom plate as shown in FIG. 6 and a concave portion 14 is formed along the circumferential direction of the inner surface of the side wall. Use an inner plate with. The same apparatus as in Example 1 was used for filling the inner plate with the cosmetic, and the cosmetic was filled up to the concave portion 14, and the center A of the surface of the cosmetic was above the contact line B between the side wall and the cosmetic. So that it gets excited. Other manufacturing steps are the same as in the first embodiment. When the cosmetic solidifies, the surface of the cosmetic becomes B
And the surface of the cosmetic becomes smooth. By providing a concave portion instead of a convex portion on the inner plate 1, when using the inner plate having the convex portion, when using the cosmetic filled below the convex portion, The protrusion does not become an obstacle. According to the above constitution, it is possible to prevent cracks or sink marks from being generated on the surface of the cosmetic after solidifying the fluid cosmetic. This makes it possible to obtain a beautifully filled middle plate filling cosmetic. In addition, it is possible to prevent the oil quality of the cosmetic from accumulating in cracks or sink marks, and prevent the quality of the cosmetic from deteriorating due to accumulation of dust.
