Description

  The present invention relates to a cosmetic molding apparatus and molding method. More specifically, the present invention relates to an improvement in the structure of an apparatus for molding stick-shaped cosmetics such as lipstick, and further to a molding method using the molding apparatus.

  A cosmetic is known in which a part of a molded cosmetic such as lipstick can be attached to and removed from a middle dish in a container, and the amount of protrusion from the container can be adjusted by turning a dial, for example.

Conventionally, as a method for molding such cosmetics into a predetermined shape (for example, a bar shape or a stick shape), a molding method using a mold (metal mold) is often used. In this case, a cosmetic formed in a predetermined shape is obtained by filling the cavity formed in the mold with a molten cosmetic and solidifying the cavity (for example, see Patent Document 1).
JP-A-8-354

  However, for example, when a part of the cosmetic material having a predetermined shape as described above is loaded into the inner plate, depending on the structure, the tip of the container may interfere with the mold, and a part of the cosmetic material (for example, the main body) In some cases, it may not be possible to load the loading portion including a portion other than the portion to the back of the middle dish.

  Accordingly, the present invention provides a cosmetic molding apparatus and molding method that allow a part of cosmetic to be loaded into the inner plate in the cosmetic container so that it can be loaded to the back of the inner plate. The purpose is to do.

  In order to solve this problem, the present inventor has made various studies. For example, many cosmetics such as lipsticks that are formed in a stick shape (stick shape) have a shape whose tip is cut obliquely in consideration of ease of application, design, and the like. For example, if lipsticks are roughly classified, they can be divided into two types: a type called a cannonball type and a type called a slim type that is thinner than this, but in the case of a slim type, the cosmetic itself is thin. Even so, the tip of the container may be cut obliquely according to the shape of the tip of the cosmetic so that the user can easily apply it.

  In addition, when a part of the cosmetic is loaded into the middle dish, the mold of the loading portion having a small diameter is removed from the cosmetic molded with the separable mold, and the loading part is exposed to the middle dish. A method of pushing the container toward the cosmetic so as to be loaded is adopted. However, when the tip of the container is cut obliquely as described above, the tip portion and other mold (for example, lower mold or rubber mold) interfere with each other, resulting in a cosmetic loading portion. It may be difficult to load to the back of the middle dish. On the other hand, cutting the tip of the container or the cosmetic itself at an angle is important in terms of ease of application and design for the user as described above. It was considered suitable to be able to load a part of the cosmetics into the inner dish by improving the structure of the mold.

  Under the above idea, the present inventor who has further studied focusing on the structure of the mold has come to obtain knowledge that leads to the solution of such problems. The present invention is based on such knowledge, and when molding a rod-shaped cosmetic material that can be accommodated in a container, a molding apparatus that molds a part of the cosmetic material as a loading unit that can be loaded in the middle dish in the container. And when the said loading part is loaded in the said inner tray, the step part for avoiding that a part of said container and a part of the said shaping | molding apparatus interfere is formed, It is characterized by the above-mentioned. Is.

  The step part formed in a part of this molding apparatus (for example, a mold for molding the loading part or another mold) keeps the loading part away from a mold that may interfere with the tip of the container, Alternatively, a space or a gap is formed into which the front end of the container enters, so that interference between a part of the container and a part of the molding apparatus is avoided when the loading unit is loaded into the inner dish. According to this, when a part of the cosmetic is loaded into the middle plate in the cosmetic container, it is possible to load the inner plate to the back of the middle plate.

  For example, the step portion is formed so as to change the relative position of the loading portion with respect to the molding apparatus. This step portion makes the relative position of the loading portion closer to the container, or in other words, keeps the loading portion away from a mold (mold) that may interfere with the tip of the container at the time of loading. In such a case, when the loading unit is loaded into the intermediate dish, it is possible to avoid interference between a part of the container (for example, the tip part of the container) and a part of the molding apparatus (for example, the lower mold). It becomes possible to load a part of the cosmetic (loading part) to the back of the middle dish.

  In this case, the said step part forms a level | step difference in the boundary part of the main-body part of the said cosmetics, and the said loading part. Usually, the loading portion loaded in the inner dish has a smaller diameter than the main body portion. According to the step portion of the molding apparatus according to the present invention, a step based on such a difference in diameter can be formed between the main body portion and the loading portion.

  Moreover, the molding apparatus according to the present invention molds at least a part of the cosmetic except for the first mold that molds at least a part other than the loading section, and is removable from the first mold. The second mold is configured to change the relative position of the loading unit with respect to the second mold, and when the loading unit is loaded into the inner tray, The step portion for avoiding interference between a part and the first mold is formed. In the case of such a molding apparatus, the second mold is attached to the first mold, the cavity formed in both of them is filled with cosmetics, the second mold is removed after solidification, and thereby the loading portion is exposed. Let the state be Thereafter, the container is pushed in so as to cover the cosmetic, and the loading unit is loaded into the inner dish. At this time, the step formed in the mold changes the relative position of the loading unit with respect to the molding apparatus, and when the loading unit is loaded into the inner tray, a part of the container interferes with the first mold. So that you can avoid doing that. Therefore, the cosmetic molded by the molding apparatus can be loaded to the back of the middle dish.

  In this case, it is also preferable that at least a portion including the boundary with the cosmetic is inclined among the boundary surfaces of the first mold and the second mold. As described above, when the mold formed by filling the cavity formed by the first mold and the second mold is performed, the boundary between the first mold and the second mold is formed on the outer periphery of the cosmetic. In some cases, a boundary line (linear trace) may remain. In this regard, in the present invention, since the part including the boundary with the cosmetic material is inclined among the boundary surfaces of both types, the boundary line (linear trace) is also inclined along the same. For example, when the tip of the container has a shape cut obliquely as described above, if the boundary line of the outer periphery of the cosmetic is inclined in this way, it can be hidden and hidden from the tip of the container. . In this case, the inclined portion is preferably formed in accordance with the inclination of the tip of the container.

  Moreover, the said step part may be formed by the recessed part into which a part of said container enters when the said loading part is loaded in the said inner tray. A space or a gap is formed by the concave portion, and a part of the container can be inserted into the space. Therefore, the container can be pushed further deeper while avoiding interference. Therefore, when the cosmetic loading section is loaded into the inner plate, the makeup is avoided while avoiding interference between a part of the container (for example, the tip of the container) and a part of the molding apparatus (for example, the lower mold). It becomes possible to load a part of the material (loading part) to the back of the middle dish.

  In the present invention, the molding device molds at least a part of the cosmetic except for the first mold that molds at least a part other than the loading section, and is detachable from the first mold. It consists of a 2nd type | mold, The convex part fitted to the said recessed part formed in the said 1st type | mold is formed in the said 2nd type | mold. In the case of such a molding apparatus, the second mold is attached to the first mold, the cavity formed in both of them is filled with cosmetics, the second mold is removed after solidification, and thereby the loading portion is exposed. Let the state be Thereafter, the container is pushed in so as to cover the cosmetic, and the loading unit is loaded into the inner dish. At this time, since the first mold is formed with a recess into which a part of the container can enter, when the loading unit is loaded into the inner dish, the part of the container and the first mold are separated from each other. Interference can be avoided. Moreover, the convex part currently formed in the 2nd type | mold functions so that it may fit in the recessed part of a 2nd type | mold, when a mold | die is attached, and the cosmetics are filled with the said recessed part.

  In this case, it is preferable that the concave portion is formed in a shape inclined in accordance with the inclination of the tip of the container. When the tip of the container has a shape cut obliquely, the tip can be inserted into such a recess.

  In such a molding apparatus, it is preferable that the first mold includes an elastic mold filled with the cosmetic and a mold on which the elastic mold is mounted. The mold having elasticity is a rubber mold made of, for example, silicon rubber. When molding a soft cosmetic material, it is preferable to perform molding in a state where an elastic mold such as a rubber mold is interposed. In addition, according to the molding method performed with a rubber mold or the like interposed in this way, there is an advantage that cosmetics with a beautiful appearance and rich in design can be molded. Therefore, it is suitable to be applied to a cosmetic material having a solid property at normal temperature, and further has an advantage that it is possible to mold a cosmetic material having a shape that is difficult with a normal mold. According to the present invention, it is possible to mold such a soft material cosmetic, a cosmetic with a beautiful appearance, and a cosmetic with high designability. Interference with a part (for example, rubber mold) can be avoided.

  The molding apparatus as described so far is suitable as an apparatus for molding a stick-shaped cosmetic material such as a lipstick.

  Further, the present invention is a cosmetic molding method for molding a stick-shaped cosmetic material that can be accommodated in a container, wherein a part of the cosmetic material is molded as a loading portion that can be loaded in a middle dish in the container. The cosmetic molding apparatus according to any one of claims 1 to 12, wherein a part of the container and a part of the molding apparatus interfere when the loading unit is loaded into the inner dish. The cosmetic is molded while avoiding the above.

  By using the molding apparatus as described above, the relative position of the loading unit is further moved closer to the container. In other words, the loading unit is moved away from a mold (mold) that may interfere with the tip of the container during loading. be able to. According to this, when the loading unit is loaded into the middle dish, it is possible to avoid interference between a part of the container (the tip part of the container) and a part of the molding apparatus (for example, the lower mold). It becomes possible to load a part of the cosmetic (loading part) to the back of the inner plate.

  In the molding method of the present invention, the molding apparatus includes a first mold that molds at least a part other than the loading unit, and is attachable to and detachable from the first mold, and at least the loading unit of the cosmetic. The first mold is composed of an elastic mold filled with the cosmetic material and a mold to which the mold is attached. In this molding method, the second mold is first attached to the first mold, the cosmetic material is filled into the cavity formed inside the two molds, the second mold is removed after solidification, and thereby the loading portion is exposed. State. Thereafter, the container is pushed in so as to cover the cosmetic, and the loading unit is loaded into the inner dish. At this time, the step formed in the mold changes the relative position of the loading unit with respect to the molding apparatus, or secures a space or gap for the container tip to enter, and the loading unit is loaded into the inner dish. In this case, it is possible to avoid interference between a part of the container and a part of the apparatus. Therefore, the cosmetic molded by this molding method can be loaded to the back of the middle dish. Moreover, according to this molding method using an elastic mold such as a rubber mold, it is possible to mold a soft cosmetic material, a cosmetic material with a beautiful appearance, and a cosmetic material rich in design.

  Furthermore, in the molding method according to the present invention, the second mold is attached to the first mold, the cosmetic material is filled in a cavity formed inside the mold having elasticity, and the second mold is solidified. The mold is removed, and the exposed loading portion is loaded relative to the container inner tray, and after loading, the body portion of the cosmetic is extracted from the elastic mold.

  According to the present invention, when a part of the cosmetic is loaded into the middle dish in the cosmetic container, it is possible to load the middle dish to the back.

  Hereinafter, the configuration of the present invention will be described in detail based on an example of an embodiment shown in the drawings.

  1 to 8 show an embodiment of a cosmetic molding apparatus and molding method according to the present invention. The molding apparatus 1 is an apparatus for molding a part of the cosmetic 3 as a loading portion 3a that can be loaded into the middle dish 2a in the container 2 when molding the stick-shaped cosmetic 3 that can be accommodated in the container 2. It is. In the present embodiment, by changing the relative position of the loading unit 3a with respect to the molding apparatus 1, when the loading unit 3a is loaded into the intermediate dish 2a, a part of the container 2 and a part of the molding apparatus 1 are The step portion 8 that can avoid the interference is formed.

  In the embodiment described below, a case where the present invention is applied to a stick-shaped (stick-shaped) lipstick as an example of the cosmetic 3 will be described. However, the lipstick shown here is only an example of the cosmetic 3, and besides this, stick-shaped cosmetics in various cosmetics such as concealer, foundation, eyebrow, eyeliner, eye shadow, mascara, teak, manicure, pedicure and lip balm. Naturally, it is possible to apply the present invention to 3.

  The container 2 is a member that accommodates the cosmetic 3, and is formed in a cylindrical shape that is open only at the tip, for example, in the case of the present embodiment that accommodates the stick-shaped cosmetic 3 (see FIG. 7 and the like). Further, a larger diameter portion (indicated by reference numeral 2c in FIG. 8) thicker than this is formed on the proximal end side of this cylindrical small diameter portion (indicated by reference numeral 2b in FIG. 8). The small-diameter portion 2b and the large-diameter portion 2c have a structure that can rotate relatively. The open end portion of the container 2 (the end portion of the small-diameter portion 2b) is cut obliquely so that it can be easily applied and the design can be improved even when the cosmetic 3 is thin. In addition, when the cosmetic 3 is not used, the cap (lid container) 9 can be covered on the small-diameter portion 2b with the cosmetic 3 retracted. The cap 9 is formed to have an outer diameter equal to that of the large diameter portion 2c so as to be integrated with the large diameter portion 2c when covered (see FIG. 8).

  Further, inside the container 2 is provided an inner plate 2a for holding the cosmetic 3 in a state in which a part of the cosmetic 3 (specifically, the loading unit 3a) is loaded (see FIG. 7 and the like). ). The inner tray 2a is provided so as to be movable in the axial direction within the container 2 so that the cosmetic 3 can be taken out or retracted by a desired amount from the front end portion (open end) of the container 2. It has become. Although not particularly illustrated, the mechanism for moving the inner tray 2a in the axial direction is constituted by, for example, a screw mechanism or a cylindrical cam mechanism having a spiral structure, and the small diameter portion 2b and the large diameter portion 2c of the container 2 are arranged. The inner tray 2 a moves in the container 2 by an amount corresponding to the relative rotation amount.

  The molding apparatus 1 is an apparatus that molds the stick-shaped cosmetic 3 that can be accommodated in the container 2 described above. For example, in the case of the present embodiment, the molding apparatus 1 is constituted by a split mold comprising a separable mold, that is, a first mold 4 and a second mold 5 that can be attached to and detached from the first mold 4. (See FIG. 1 etc.).

  The first mold 4 is used as, for example, a lower mold among split molds (hereinafter also simply referred to as a lower mold). The lower mold 4 in the present embodiment is provided with a recess in the center portion, and a portion of the cosmetic 3 other than the loading portion 3a, that is, a portion that is actually used as the cosmetic 3 (in this specification, this portion is the main body. At least a part of the portion 3b).

  The second mold 5 is used as an upper mold that can be attached to and detached from the lower mold 4 described above (hereinafter also simply referred to as an upper mold). In the present embodiment, the upper mold 5 is provided with a through-hole at the center portion, and the molten cosmetic material 3 is filled from the upper opening (see FIG. 3). At least a part of the molding cavity 7 is formed by the recess provided in the lower mold 4 and the through-hole provided in the upper mold 5.

  Although the cosmetic 3 can be molded using the two molds of the lower mold 4 and the upper mold 5 described above, the elastic mold 6 is further used as a part of the lower mold in this embodiment. I am going to do that. The material of the mold 6 having such elasticity is not particularly limited. For example, in this embodiment, a rubber mold made of silicon rubber (hereinafter also referred to as a rubber mold) is used as the lower mold 4 and the cosmetic 3. (See FIG. 3 etc.). The rubber mold 6 or the like is suitable for molding a cosmetic material 3 that is particularly soft because it can exhibit appropriate elasticity during molding. In addition, according to the molding method performed with the rubber mold 6 or the like interposed in this way, the appearance of the cosmetic 3 to be molded becomes beautiful, and it is possible to mold the cosmetic 3 having high design properties. There is also an advantage. Furthermore, it may be easy to release the molded product (cosmetic material 3) after molding.

  The rubber mold 6 of the present embodiment has an outer diameter that can be fitted into the recess (through hole) of the lower mold 4 described above, and is formed in a substantially cylindrical shape with a bottom that is open only at one end. On the opening end side, a flange portion 6a having a size to be caught in the concave portion of the lower mold 4 is provided. In addition, the inner side of the bottom portion forming the cavity 7 is formed by an inclined surface 6b, and the tip portion of the cosmetic 3 is molded obliquely (see FIG. 2 and the like).

  The rubber mold 6 is preferably formed so that its inner diameter is equal to the inner diameter of the large-diameter portion (indicated by reference numeral 5b in FIG. 2) of the recesses of the upper mold 5 (see FIG. 2 and the like). . In the case of the molding apparatus 1 according to the present embodiment, the main body 3b of the cosmetic 3 is molded by both the rubber mold 6 and the large-diameter portion 5b. It is possible to mold the outer diameter of 3b to be uniform.

  Although not particularly illustrated, it is preferable that the rubber mold 6 and the lower mold 4 are provided with positioning means for positioning the rubber mold 6 and maintaining the state thereof. According to such positioning means, when the cosmetic material 3 whose tip portion is oblique is molded and loaded into the container 2 as in the present embodiment, the relative orientation of the cosmetic material 3 with respect to the container 2 is determined. It becomes possible to make uniform. The positioning means can be constituted by, for example, at least one pin provided around the upper opening end of the lower mold 4 and a recess provided in the flange portion 6a so that these pins are fitted.

  Further, as described above, in the molding apparatus 1, the step portion 8 that changes the relative position of the loading unit 3 a with respect to the molding apparatus 1 is formed. This step 8 is for making it possible to avoid interference between a part of the container 2 and a part of the molding apparatus 1 when the loading part 3a of the cosmetic 3 is loaded into the inner tray 2a. For example, in the case of this embodiment, it is formed in the middle of the recess of the upper mold 5 (see FIG. 1 and the like). The concave portion of the upper mold 5 is composed of a small diameter portion 5a and a larger diameter portion 5b larger than the small diameter portion 5a. Mold each one. The step portion 8 of the present embodiment is a step portion formed between the small diameter portion 5a and the large diameter portion 5b, and forms a step at the boundary portion between the main body portion 3b of the cosmetic 3 and the loading portion 3a.

  More specifically, the step portion 8 of the present embodiment is such that the distance from the step portion 8 to the upper surface of the rubber mold 6 (or the upper surface of the lower mold 4) is from the middle plate 2a at the time of loading to the container. 2 is formed at a position larger than the distance to the tip of 2 (see FIG. 6 and the like). For example, in the case of a conventional general mold, the boundary between the lower mold 4 and the upper mold 5 is a step, that is, the lower mold 4 is the body 3b of the cosmetic 3 and the upper mold 5 is the loading section 3a. It is designed to be molded. On the other hand, in the case of the molding apparatus 1 of the present embodiment, the relative position of the loading portion 3a is further closer to the container 2, and the depth required for loading is ensured by moving away from the lower mold 4. When the loading unit 3a is loaded into the intermediate dish 2a, a part of the container 2 (the tip part of the container 2) and a part of the molding apparatus 1 (for example, the upper surface of the rubber mold 6 or the upper surface of the lower mold 4) interfere with each other. Can be avoided. Therefore, it becomes possible to load a part of the cosmetic 3 (loading portion 3a) to the back of the inner tray 2a (see FIG. 6 and the like).

  Next, an example of a molding procedure when the molding apparatus 1 as described above is used will be described with reference to the drawings.

  First, the upper die 5 is attached to the lower die 4 in a state where the rubber mold 6 is fitted in the recess (through hole) of the lower die 4 (see FIGS. 1 and 2). At this point, a cavity 7 serving as a molding space is formed inside the upper mold 5 and the rubber mold 6.

  Next, cosmetics are filled in the molding apparatus 1. For example, in this embodiment, the filling nozzle 10 is used to fill the melted cosmetic material 3 from the upper opening of the upper mold 5 toward the cavity 7 to the upper opening (see FIG. 3). When the filling is completed, the cosmetic 3 is cooled and solidified by, for example, blowing cool air to the bottom of the rubber mold 6 or cooling the lower part of the lower mold 4 with chiller water (see FIG. 4). In addition, in the present embodiment, hot air is blown from above the upper mold 4 toward the loading portion 3a of the cosmetic 3 together with this. According to this, it can solidify after correcting the shape of the shrinkage | contraction opening | mouth (end surface part of the cosmetics 3 deform | transformed by cooling) of the cosmetics 3 accompanying cooling.

  When the cosmetic 3 is solidified, the upper mold 5 attached to the lower mold 4 is removed. Thereby, it will be in the state which the loading part 3a of cosmetics 3 exposed (refer FIG. 5).

  Thereafter, the container 2 is pushed in an inverted posture so as to cover the cosmetic 3 (see FIG. 6). Thereby, the loading part 3a of the cosmetics 3 is loaded into the inner tray 2a. Here, as described above, in the molding apparatus 1 according to the present embodiment, the step portion 8 formed on the upper mold 5 changes the relative position of the loading portion 3a toward the container 2, and the loading portion 3a becomes the middle dish 2a. This prevents a part of the container 2 and the lower mold 4 from interfering with each other. Therefore, according to the molding method of the present embodiment, it is possible to load the loading portion 3a of the cosmetic material 3 to the back of the middle dish 2a.

  Finally, remove the molded product. Here, the container 2 is moved upward in an inverted posture, whereby the cosmetic 3 is extracted from the rubber mold 6 (see FIG. 7). According to the present embodiment in which the loading unit 3a can be loaded to the back of the middle dish 2a as described above, when the cosmetic 3 is extracted in this way, the cosmetic 3 and the container 2 are in an integrated state. Easy to keep. By the above molding procedure, the cosmetic 3 accommodated in the container 2 can be obtained in a state where the loading portion 3a is loaded to the back of the middle dish 2a (see FIG. 8).

  As described above, as is apparent from the above description, according to the molding apparatus 1 of the present embodiment and the molding method using the molding apparatus 1, one of the cosmetics 3 is placed on the inner dish 2 a in the container 2 of the cosmetics 3. When loading the portion (loading portion 3a), it is possible to load the inner tray 2a as far as it will go. For example, in the present situation, the tip of the container 2 or the cosmetic 3 itself may be cut obliquely in terms of ease of application, design, and the like, whereas in the present embodiment, the loading portion 3a is extended to the back of the middle dish 2a. The cosmetic 3 having a shape that can be loaded can be molded.

  Moreover, in the present embodiment, after the cosmetic 3 is molded, the container 2 can be pushed in with only the upper mold 4 removed, and the loading portion 3a can be loaded into the inner tray 2a. As a method for molding the cosmetic 3, there is a method in which only a mold (metal mold) is used, and the molded cosmetic 3 is taken out of the mold and loaded into the intermediate dish 2a of the container 2. According to the method, there is an advantage that the labor and procedure can be simplified as compared with this.

  In addition, the molding apparatus 1 and the molding method as described above are particularly suitable for application to a slim bar-shaped cosmetic 3 of a type called a slim type. In the case of the so-called shell-shaped cosmetic 3 having a tapered shape, a gap is formed between the cosmetic 3 and the container 2, whereas the diameter is substantially constant except for the tip portion that is obliquely cut. In the case of the slim type, almost no gap is formed between the cosmetic 3 and the container. In this respect, the molding apparatus 1 and the molding method of the present embodiment using the molds (lower mold 4 and upper mold 5) having an improved structure and the rubber mold 6 having elasticity are relatively difficult to mold. This is particularly suitable for slim type cosmetics 3. Of course, it is needless to say that the present invention is suitable not only for the slim type but also for the shell-type cosmetic 3 as described above.

  The above-described embodiment is an example of a preferred embodiment of the present invention, but is not limited thereto, and various modifications can be made without departing from the scope of the present invention. For example, in this embodiment, the rubber mold 6 is interposed as a part of the lower mold 4 between the lower mold 4 and the cosmetic 3 to be molded. The rubber mold 6 can be interposed between them. In this case, the rubber mold 6 may be interposed on the entire surface of the concave portion of the upper mold 5, or the rubber mold 6 may be interposed only on a part thereof (for example, the large diameter portion 5b of the concave portion of the upper mold 5). Also good.

  Further, in this embodiment, the small-diameter portion 5a and the large-diameter portion 5b having different inner diameters are provided in the concave portion of the upper mold 5 and the step portion at the boundary between them is defined as a step portion 8. It is also possible to form with a mold having elasticity such as. For example, as described above, the rubber mold 6 can be interposed only in the large-diameter portion 5 b of the concave portion of the upper mold 5, and the step portion 8 can be formed using the edge of the rubber mold 6.

  In the present embodiment, molds are used as the lower mold 4 and the upper mold 5, but this is only an example. For example, a mold made of heat-resistant cured resin or the like can be used as the lower mold 4 or the upper mold 5.

  Furthermore, in the above-described embodiment, the boundary surface between the lower mold 4 and the upper mold 5 is a horizontal and flat surface (see FIG. 1 and the like). Of this boundary surface, a portion including at least the boundary with the cosmetic 3 It is good also as inclining (refer FIGS. 9-11). When filling the cavity 7 formed by the lower mold 4 (rubber mold 6) and the upper mold 5 with the cosmetic 3 and molding it, the lower mold 4 (rubber mold 6) is placed on the outer periphery of the main body 3b of the cosmetic 3. In some cases, a boundary line (linear trace) along the boundary between the upper mold 5 and the upper mold 5 may remain. However, according to the molding apparatus 1 as in the second embodiment described below, such a boundary line is obscured. It is possible to mold the cosmetic 3 as described above.

  That is, about the lower mold | type 4 and the upper mold | type 5, let the mold | type center belt | band including the boundary part with the cosmetics 3 be an inclined surface (refer FIG. 9, FIG. 10). Further, for the rubber mold 6, the upper surface including the flange portion 6a is inclined in the same manner as the lower mold 4 and the upper mold 5 (in FIG. 10, etc., the inclined surfaces of the upper mold 5 and the rubber mold 6 are denoted by reference numerals 5s and 6s, respectively. Shown). In the case of such a molding apparatus 1, the boundary between the lower mold 4 (rubber mold 6) and the upper mold 5 and the cosmetic 3 is an inclined circle (more specifically, an inclined ellipse). Therefore, the boundary line (indicated by reference numeral 3c in FIG. 9 and the like) of the outer periphery of the main body of the cosmetic 3 also has an inclined circle shape (inclined ellipse) (see FIGS. 9 and 10). When the tip of the container 2 is cut obliquely like a slim type lipstick, the cosmetic 3 (loading part 3a) is placed in the container 2 (inside, depending on the relative position of the boundary 3c. When loaded on the dish 2a), the boundary line 3c can be hidden from the tip of the container 2 (see FIG. 11). In this case, it is preferable that the slopes of the inclined surfaces 5s and 6s are matched with the slope of the container tip so that the boundary line 3c coincides with the tip of the container 2.

  In addition, although the case where each inclined surface (for example, inclined surface 5s, 6s) is a plane was illustrated here (refer FIG. 10 etc.), it can also be made into a curved surface. In short, the boundary line 3c that can remain on the outer periphery of the main body 3b of the cosmetic 3 is the shape of the boundary between the lower mold 4 (rubber mold 6) and the upper mold 5 and the cosmetic 3 As long as the boundary can be formed into a desired shape, the inclined surface may be a flat surface or a curved surface.

  Further, the description has been made so far on the case where the step portion 8 changes the relative position of the loading portion 3a in the molding apparatus 1. However, the interference between the tip of the container 2 and the lower mold 4 (rubber mold 6) is avoided. From this point of view, the stepped portion 8 can have another form. Hereinafter, an example will be described as the third embodiment (see FIGS. 12 to 14).

  The step 8 in the present embodiment is formed by a concave portion 8a into which a part of the container 2 can enter when the loading portion 3a is loaded into the inner tray 2a (see FIG. 13 and the like). Such a recess 8a allows a part of the container 2 to enter the space or gap, so that the container 2 is further deepened while avoiding interference with the lower mold 4 and the rubber mold 6, for example. You can push in. Therefore, it is possible to load the loading portion 3a of the cosmetic material 3 to the back of the middle dish 2a while avoiding interference between the tip portion of the container 2 and the rubber mold 6 or the like.
