[0009] Hereinafter, modes for carrying out a soap product and a method for producing a soap product will be described. The soap product of the present embodiment is a product including soap and a packaging film. The method for producing a soap product of the present embodiment is a method for producing a soap product, and includes a step of molding soap, a step of packaging the molded soap, and the like. In this embodiment, the soap product is described assuming it is placed on a horizontal surface, and for example, the side facing upwards is referred to as the top surface. Furthermore, the inside and outside are defined with respect to the soap, with the side facing the soap being referred to as the "inside" and the side opposite the inside being referred to as the "outside." Note that the term "surface" used in this embodiment does not mean the front surface, but rather the outer surface.

[0010] [I. One Embodiment] In the embodiment described below, the composition of the soap product is described in item [1], and the composition of the soap product manufacturing method is described in item [2]. Then, the function and effect of the composition of items [1] and [2] are described in item [3].

[0011] [1. Soap products] As shown in Figure 1, in soap product 1, the soap 2 is wrapped in packaging film 3. The soap 2 (i.e., soap product 1) wrapped in packaging film 3 may be placed in packaging such as a cosmetic box or cosmetic bag, which are not shown. The soap product 1 may include not only the soap 2 and the packaging film 3, but also a barrier film 4 (shown as a dashed line in Figure 1) interposed between the soap 2 and the packaging film 3.

[0012] The soap product 1 described above can take on various forms depending on the packaging of the soap 2 by the packaging film 3. Examples of such soap products 1 include the first soap product 11, in which the soap 2 is packaged in the packaging film 3 in a double-wrap (so-called "caramel wrap") form as shown in Figure 2, and the second soap product 12, in which the soap 2 is packaged in the packaging film 3 in a pillow-wrap form as shown in Figure 3.

[0013] In addition, although not shown in the illustration, a third soap product (i.e., a stretch-packaged product) in which soap 2 is packaged in a packaging film 3 in a stretch-packaging form can also be cited as an example of soap product 1. Here, "stretch-packaging type" refers to a type in which the stretchable packaging film 3 is stretched and packaged. Stretch packaging includes packaging in which the stretchable packaging film 3 is stretched and tightly attached to the soap 2, and packaging in which the shrinkable packaging film 3 is shrunk and tightly attached to the soap 2.

[0014] Compared to the stretch packaging type for the third soap product, the overlapping packaging type for the first soap product 11 and the pillow packaging type for the second soap product 12 are, simply put, loosely packaged. In each of the above-mentioned first soap product 11, second soap product 12, and third soap product, the area S in contact with the soap 2 by the packaging film 3 is the following three areas S1, S2, and S3. • First area S1: The area S in which the packaging film 3 is in contact with the soap 2 in the first soap product 11. • Second area S2: The area S in which the packaging film 3 is in contact with the soap 2 in the second soap product 12. • Third area S3: In the third soap product, the soap 2 is covered with a packaging film 3 (predetermined film). The area S (predetermined area) that comes into contact with it.

[0015] The areas S1, S2, and S3 shown above are smaller for the first area S1 and second area S2 than for the third area S3 because the overlapping wrap and pillow wrap types are more loosely packaged compared to the stretch wrap type. Therefore, the inequalities "third area S3 > first area S1" and "third area S3 > second area S2" hold true. Furthermore, if the pillow-wrap type packaging is more loosely fitted than the overlap-wrap type packaging, then the second area S2 is smaller than the first area S1, and the inequality "first area S1 > second area S2" holds. Conversely, if the overlap-wrap type packaging is more loosely fitted than the pillow-wrap type packaging, then the first area S1 is smaller than the second area S2, and the inequality "second area S2 > first area S1" holds.

[0016] The following describes soap product 1, soap 2, and packaging film 3. Then, a description of barrier film 4 is added. [1-1. Soap] Soap 2 is a solid, white soap. In other words, Soap 2 can be described as a solid white soap or white soap, or simply a white solid soap.

[0017] In this embodiment, "solid" refers to a form that is composed of a specific shape (i.e., has a fixed shape), rather than a form that is not liquid or powder and does not have a fixed shape. Furthermore, in this embodiment, "white" means that if soap 2 changes color to yellow (hereinafter referred to as "yellowing"), that yellowing will result in a color that is perceptible to the user of soap product 1. Therefore, "white" in this embodiment is not limited to pure white or stark white, but also includes colors that have a faint hue (so to speak, "almost white") in which the yellowing of soap 2 is perceptible to the user. In other words, a color that is not "white" in this embodiment is, for example, the color of conventional soap containing licorice extract, and it means that when such conventional soap yellows, that yellowing will result in a color that is imperceptible to the user.

[0018] Soap 2 of this embodiment contains at least licorice extract. Licorice extract is a beauty ingredient that is expected to have anti-inflammatory, skin-soothing, anti-allergic, and acne, blemish, and freckle-preventing effects. The licorice extract exemplified here is a water-soluble extract derived from licorice. Furthermore, soap 2 contains mostly lipophilic components, with the exception of the water-soluble licorice extract. Therefore, if soap 2 contains or has moisture on it, the licorice extract will easily dissolve in that moisture.

[0019] Soap 2 may contain known ingredients in addition to licorice extract. However, it is preferable that soap 2 in this embodiment does not contain antioxidants. For example, soap 2 contains surfactants, oily components, sugars, fatty acids, inorganic salts, chelating agents, plant extracts, cationic polymers, antibacterial agents, fragrances, pigments, dyes, hypoallergenic agents, water, etc.

[0020] The shape of soap 2 can be any shape, such as a rectangular parallelepiped or a cylindrical shape. Figure 1 shows an example of soap 2 molded into a predetermined outer shape that is roughly rectangular. In this embodiment, the soap 2 has a pattern 2P, which is finer than the rectangular parallelepiped shape, recessed on its top surface 2U. Various shapes such as product names, characters, and corporate marks can be used for this pattern 2P. Note that the recessed areas of the pattern 2P are not limited to the top surface 2U of the soap 2, but may also be on the bottom surface facing downwards or on the side surfaces facing horizontally. However, the soap 2 does not necessarily need to have pattern 2P recessed into it.

[0021] [1-2. Packaging film] Incidentally, the inventor of this embodiment discovered a problem in which the soap 2 yellows when an antioxidant comes into contact with the licorice extract contained in the soap 2. Therefore, based on the knowledge that the yellowing of the soap 2 should be suppressed, the soap product 1 of this embodiment employs a packaging film 3 that prevents or minimizes contact between the antioxidant and the soap 2. Furthermore, it is presumed that conventional soaps containing licorice extract, which are not "white" as defined in this embodiment, have not been recognized as having a defect caused by licorice extract, because the yellowing of conventional soaps is not a color that can be perceived by the user.

[0022] In this embodiment, three types of packaging films 3 are described below with reference to Figures 4, 5, and 6. • First packaging film 31: Packaging film 3 that does not contain antioxidants • Second packaging film 32: Packaging film 3 consisting of an unstretched film containing an antioxidant. • Third packaging film 33: Multilayer packaging film containing antioxidants 3

[0023] In Figure 4, which shows the first packaging film 31, the antioxidant is not shown because the first packaging film 31 does not contain an antioxidant. On the other hand, in Figure 5, which shows the second packaging film 32 containing an antioxidant, and in Figure 6, which shows the third packaging film 33 containing an antioxidant, the antioxidant is schematically shown as a white circle. Note that Figure 5 shows not only the second packaging film 32, which is made of an unstretched film, but also the stretched film 3a.

[0024] As the "antioxidant" for packaging films 31, 32, and 33, known antioxidants, including lipophilic antioxidants that may be contained in packaging film 3, can be used. Examples of such antioxidants include hindered phenol antioxidants, phosphorus antioxidants, phosphorus processing stabilizers, and hindered phenol antioxidants. Specific examples of antioxidants include IRGANOX® registered trademarks such as Irganox1076 (BASF Japan Ltd.), Irganox1010 (BASF Japan Ltd.), and Irgafos168 (BASF Japan Ltd.), as well as BHT (dibutylhydroxytoluene).

[0025] As shown in Figure 5, the second packaging film 32, which is made of an unoriented film, is a film that has not undergone stretching during the manufacturing process and may also be called an unoriented film or non-stretched film. When this second packaging film 32 (i.e., the unoriented film) is subjected to stretching (i.e., stretching), it becomes an oriented film 3a. In other words, the oriented film 3a is a film that has undergone stretching during its manufacturing process.

[0026] The second packaging film 32, which is made of an unoriented film containing an antioxidant, tends to have less surface exposure of the antioxidant compared to the stretched film 3a containing an antioxidant. For example, in the second packaging film 32, which is made of an unoriented film containing an antioxidant, the antioxidant is contained internally without being exposed on the surface. On the other hand, the stretched film 3a containing an antioxidant becomes thinner when stretched, and some of the antioxidant that was contained internally without being exposed on the surface before stretching becomes more easily exposed on the surface.

[0027] As shown in Figure 6, the "multilayer structure" of the third packaging film 33 is a structure having multiple layers (also called "layers"). The multilayer structure may be a structure in which different types of layers are stacked, or a structure in which the same type of layers are stacked. For example, materials that can be used for each layer include PE (Polyethylene), PP (Polypropylene), NY (Nylon), and rayon. Specific examples of a two-layer third packaging film 33 among the multilayer structures include a structure consisting of a PE layer and a PP layer, a structure consisting of two layers of PE, and a structure consisting of a PE layer and a rayon layer.

[0028] A "single-layer structure" is a structure that has only one layer. The layers in a single-layer structure can also be made from the aforementioned materials such as PE, PP, NY, and rayon. In addition, the packaging films 31, 32, and 33 can be made of materials with any desired light-transmitting properties, such as transparent or opaque, and can be made of materials with any desired finish, such as matte or glossy.

[0029] As shown in Figure 4, the first packaging film 31 does not need to contain any antioxidants, and may have a single-layer structure (i.e., a single-layer film) or a multi-layer structure (i.e., a multi-layer film), and may be made of a stretched film or an unstretched film. In other words, the first packaging film 31 does not contain any antioxidants, has any layer structure, and is not limited to whether or not it undergoes stretching during its manufacturing process. The composition of the first packaging film 31, which does not contain antioxidants, fundamentally prevents yellowing of the soap 2.

[0030] As shown in Figure 5, the second packaging film 32 contains an antioxidant and is at least an unoriented film, and may have a single-layer or multi-layer structure. In other words, the second packaging film 32 consists of an unoriented film containing an antioxidant and has any layer structure. The structure of the second packaging film 32, which prevents the antioxidant from being easily exposed on the surface, helps to suppress yellowing of the soap 2.

[0031] As shown in Figure 6, the third packaging film 33 has at least a multilayer structure and may consist of stretched film or unstretched film. In other words, the third packaging film 33 has a multilayer structure, regardless of whether or not it undergoes stretching during its manufacturing process. The third packaging film 33 has an outer layer 3o containing an antioxidant on the outside and an inner layer 3i that does not contain an antioxidant on the inside. Here, "outside" refers to the side of the third packaging film 33 that is packaging the soap 2 that is opposite to the side facing the soap 2 (i.e., the side opposite to the soap 2). Here, "inside" refers to the side of the third packaging film 33 that is packaging the soap 2 that is opposite to the soap 2 (i.e., the side opposite to the outside).

[0032] In the third packaging film 33 that packages the soap 2, the inner layer 3i provided on the inside can be said to be a layer that can come into contact with the soap 2. This inner layer 3i can also be said to be a protective layer that prevents the exposure of the antioxidant on the inner surface of the third packaging film 33. Furthermore, the outer layer 3o provided on the outside of the third packaging film 33 is a layer whose contact with the soap 2 is structurally prevented by the inner layer 3i, and the inner layer 3i can be said to be a barrier layer that is responsible for this contact prevention function.

[0033] In this third packaging film 33, the antioxidant is contained in the outer layer 3o, but not in the inner layer 3i. This configuration of the third packaging film 33, in which the inner layer 3i that can come into contact with the soap 2 does not contain an antioxidant, helps to suppress yellowing of the soap 2.

[0034] [1-3. Barrier Film] Since the barrier film 4 is interposed between the soap 2 and the packaging film 3, it is separate from the packaging film 3, with the soap 2 positioned inside the barrier film 4. In other words, the packaging film 3 is positioned outside the barrier film 4. This barrier film 4 can be described as a film that prevents (so to speak, acts as a barrier) the soap 2 and the packaging film 3 from coming into direct contact.

[0035] The barrier film 4 described above does not contain antioxidants or licorice extract, and has properties that prevent or suppress the penetration or permeation of antioxidants or licorice extract from either the inside or outside of the barrier film 4 to the other. Examples of such properties include waterproofing, oil resistance, water resistance, etc. Furthermore, known materials such as PE, PP, NY, and rayon can be used as the material for the barrier film 4. In addition, the barrier film 4 may have a single-layer structure or a multi-layer structure, and may consist of a stretched film or an unstretched film.

[0036] Alternatively, an absorbent barrier film 4 may be used. In this case, moisture adhering to the surface of the soap 2 is absorbed by the barrier film 4, and the moisture is removed from the surface of the soap 2. Or, if the barrier film 4 has a multilayer structure, various functional layers may be provided in the barrier film 4, such as an absorbent layer that absorbs moisture from the surface of the soap 2, or a layer that prevents the leakage of antioxidants from the packaging film 3.

[0037] [1-4.Summary] Table 1 below shows a list of combinations of the above-mentioned soap product 1, including the packaging form of soap 2, the type of packaging film 3, and the presence or absence of barrier film 4.

[0038] [Table 1]

[0039] As shown in Table 1 above, six examples of the first soap product 11, in which the soap 2 is packaged in a packaging film 3 in a double-wrap type packaging form, are the first product A, B, C, D, E, and F. For the first products A and B, the first packaging film 31 is used as the packaging film 3. For the first products C and D, the second packaging film 32 is used as the packaging film 3. For the first products E and F, the third packaging film 33 is used as the packaging film 3. The first products A, C and E are provided with a barrier film 4. The first products B, D and F are not provided with a barrier film 4.

[0040] Furthermore, as examples of second soap products 12 in which soap 2 is packaged in a pillow-type packaging form with packaging film 3, there are six forms of second products A, B, C, D, E, and F. Second products A, B, C, D, E, and F are constructed by replacing "first" with "second" in the description of "first product" in first products A, B, C, D, E, and F. Similarly, as examples of third soap products in which soap 2 is packaged in a packaging film 3 in a stretch packaging form, there are six forms of third products A, B, C, D, E, and F. Third products A, B, C, D, E, and F are constructed by replacing "first" with "third" in the description of "first product" in first products A, B, C, D, E, and F.

[0041] [2. Method for manufacturing soap products] Next, with reference to Figure 7, a method for manufacturing soap product 1 will be described. The soap product 1, which is the target of this method, takes on various forms (eighteen forms in the example in Table 1) depending on the packaging form of the soap 2 using the packaging film 3, the type of packaging film 3, and the presence or absence of the barrier film 4, as shown in Table 1 above. The soap product 1 is manufactured using a method appropriate to each of these forms.

[0042] The soap manufacturing process involves at least the following three steps: • Preparation process: The process of preparing packaging film 3 (Step S10) • Molding process: The process of molding soap 2 (step S20) • Packaging process: The process of packaging the soap 2 with packaging film 3 (step S30)

[0043] After the preparation and molding processes are completed, a packaging process is carried out. In this packaging process, the soap 2, which was molded in the molding process, is packaged using the packaging film 3 prepared in the preparation process. Furthermore, the timing of the preparation and molding processes is arbitrary, as long as they are carried out before the packaging process. For example, the preparation and molding processes may be carried out in parallel, the molding process may be carried out before the preparation process, or the molding process may be carried out after the preparation process.

[0044] In the preparation step, the type of packaging film 3 used for soap product 1 is prepared. For example, in the case of soap product 1 of first product A and B, second product A and B, and third product A and B, the first packaging film 31 is prepared in the preparation process. Furthermore, if the soap product 1 is of the first product C and D, the second product C and D, or the third product C and D, a second packaging film 32 is prepared in the preparation step. If the soap product 1 is of the first product E and F, the second product E and F, or the third product E and F, a third packaging film 33 is prepared in the preparation step.

[0045] In the molding process, the base material of soap 2 is stamped into a predetermined outer shape using a mold. The base material of soap 2 is the material into which soap 2 is formed. This base material contains licorice extract, is white, and is solid or semi-solid. Here, "solid or semi-solid" means that it has shape retention properties that allow it to be deformed to a predetermined external shape by stamping with a mold.

[0046] In the molding process for creating soap 2 with the recessed pattern 2P, the molds used are a master mold for molding the base material into the general shape of soap 2, and an insert for creating the recessed pattern 2P. The insert is inserted and removed through a space provided in the master mold, and is a mold for molding the finer pattern 2P than the shape molded by the master mold. To elaborate, the master mold is a mold for molding the general shape, and the insert is a mold for molding the finer shape.

[0047] In the molding process using a matrix and inserts, the following two types of processes are carried out. • Base molding process: A process in which the base material is molded into the general shape of soap 2 using a master mold (step S22) • Pattern molding process: The base material is molded using a pattern 2P that is finer than the general shape of soap 2 by nesting. Step S24: A process of creating a recess and molding the soap 2 into a predetermined outer shape. Regarding the shape of soap 2, the "general shape" related to the base molding process is the shape obtained by omitting pattern 2P from the "predetermined outer shape" related to the pattern molding process.

[0048] The recess of pattern 2P is created by pressing the base material of soap 2. In other words, the pattern molding process creates a recess (so to speak, mold) by pressing the base material with a pattern finer than the predetermined outer shape. The pattern molding process illustrated here is carried out in parallel with the base molding process. However, the pattern molding process is not limited to being carried out in parallel with a portion of the base molding process; the pattern molding process may be carried out after the base molding process, or the base molding process and the pattern molding process may be carried out at different times.

[0049] Furthermore, in the molding process for forming soap 2, which does not have pattern 2P, the use of inserts is not required. Therefore, in the molding process, the pattern molding process is not performed (in other words, no pressing is done), and only the process of forming soap 2 by pressing the base material into a predetermined outer shape with a mold (in other words, the base molding process) is performed.

[0050] In the packaging process, the soap 2 is packaged with a packaging film 3 in the form used for soap product 1. For example, if the first soap product 11 is product I, II, III, IV, III, or IV, the soap 2 is packaged in a combined-wrap type form by the packaging film 3 during the packaging process. Furthermore, if the second soap product 12 is product a, b, c, d, e, or f, the soap 2 is packaged in a pillow-type packaging form by the packaging film 3 during the packaging process. If the third soap product is product a, b, c, d, e, or f, the soap 2 is packaged in a stretch-type packaging form by the packaging film 3 during the packaging process.

[0051] Furthermore, when manufacturing soap products 1 that are equipped with a barrier film 4, such as the first products A, C, and E, the second products A, C, and E, and the third products A, C, and E, an interposition process (step S32) is performed in the packaging process to place the barrier film 4 on the soap product 1. In the interposition process, the barrier film 4 is interposed between the packaging film 3 and the soap 2. Furthermore, when manufacturing soap products 1 that do not have a barrier film 4, such as the first products (Ro, Ni, and He), the second products (Ro, Ni, and He), and the third products (Ro, Ni, and He), the soap 2 is packaged with the packaging film 3 without performing an intermediary step in the packaging process.

[0052] Incidentally, the inventors of this embodiment have found that when the licorice extract contained in soap 2 is water-soluble, the licorice extract is easily dissolved into the moisture adhering to the surface of soap 2. In particular, since soap 2 is generally lipophilic, they have found that the water-soluble licorice extract tends to dissolve easily, attracted to the moisture adhering to the surface of soap 2. Furthermore, they have found that the lipophilic antioxidant contained in the packaging film 3 may move inward, attracted to the generally lipophilic soap 2. They have also found that when the antioxidant comes into contact with the moisture adhering to the surface of soap 2 and from which the licorice extract has dissolved, it causes the soap to yellow.

[0053] Furthermore, in conventional base molding and pattern molding processes, soap is molded in a mold with a gap between the insert inserted into the master mold and the master mold itself. In addition, in conventional pattern molding processes, not only the pattern but also the surrounding area of ​​the pattern (the area corresponding to the space penetrated into the master mold) is pressed by the insert, causing the pattern to be recessed, and the area around this pattern 2P is also pressed and slightly recessed. If we call the area on the surface of the base material that is slightly recessed due to being pressed by the insert the "pattern surrounding area," and the area between the pattern surrounding area and the master mold the "gap area," then a slight step is created at the boundary between the pattern surrounding area, which is slightly recessed due to being pressed by the insert in the pattern molding process, and the gap area, which is not pressed by the insert.

[0054] In conventional pattern molding processes, if the pressed substrate contains moisture, that moisture may seep out or be squeezed out and adhere to the area around the pattern. This moisture tends to accumulate along the slight step created at the boundary between the area around the pattern and the gap area. In this way, water-soluble licorice extract can easily dissolve into the moisture accumulated in the step on the surface of the soap, and if the antioxidant on the packaging film comes into contact with the moisture containing the dissolved licorice extract, it may cause the soap to yellow.

[0055] Therefore, in the pattern molding process of this embodiment, in order to avoid the occurrence of a slight step difference at the boundary between the pattern peripheral area and the gap area, only the area to be molded into a fine nested pattern 2P (hereinafter referred to as the "pattern area") is pressed. By pressing only this limited area, the pattern 2P is recessed. Furthermore, even if moisture seeps out or is squeezed out into the recessed areas of the pattern 2P, the moisture tends to adhere only to the recessed areas of the pattern 2P, thus suppressing contact between the moisture adhering to the recessed areas of the pattern 2P (and consequently the licorice extract dissolved in that moisture) and the packaging film 3.

[0056] Furthermore, in the soap product manufacturing method illustrated in this embodiment, in addition to the preparation, molding, and packaging processes described above, the following two processes are performed before and after the molding process in order to suppress the adhesion of moisture to the surface of the soap 2. • Mold wiping process: A process to wipe off moisture adhering to the mold (Step S18) • Removal process: A process to remove moisture from the surface of soap 2 (step S28)

[0057] A mold wiping process is performed before the molding process, and a removal process is performed after the molding process. The mold wiping process is based on the understanding that if moisture adheres to the mold used in the molding process, the moisture may transfer from the mold to the surface of the molded soap 2, potentially causing the aforementioned problems. Therefore, the process involves wiping away moisture from the mold used to mold the soap 2. Furthermore, the removal process is based on the understanding that if moisture adheres to the surface of the soap 2, that moisture may cause the aforementioned problems. Therefore, the process involves removing moisture from the surface of the soap 2 molded in the molding process. To elaborate on these mold wiping and removal processes, they are processes (suppression processes) that suppress the adhesion of moisture to the surface of soap 2. The mold wiping process is a process in which moisture is wiped off the mold before the soap 2 is molded in order to suppress the transfer of moisture from the mold to the surface of the soap 2. The removal process is a process in which moisture is removed from the surface of the soap 2 after it has been molded in the mold, as a precaution. Methods for removing moisture in the removal process include wiping the surface of the molded soap 2 or blowing off the moisture adhering to the surface of the molded soap 2. In addition to or instead of wiping off the moisture adhering to the mold, the mold wiping process may also be a process of blowing off the moisture adhering to the mold.

[0058] [3. Action and Effects] Because the soap product 1 and soap product manufacturing method of this embodiment have the above-described configuration, the following actions and effects can be obtained. In this section [3], the effects and benefits of soap product 1 are described in subsection [3-1], and the effects and benefits of the soap product manufacturing method are described in subsection [3-2].

[0059] [3-1. Soap Products] (1A) In the case of soap product 1 in which soap 2 is packaged with a first packaging film 31, since the first packaging film 31 does not contain an antioxidant, it is possible in principle to avoid yellowing of the soap 2 due to contact between the antioxidant and the licorice extract contained in the soap 2. Therefore, it is possible to provide a soap product 1 in which the yellowing of the soap 2 packaged with the first packaging film 31 is suppressed.

[0060] (2A) In the soap product 1 in which the soap 2 is packaged with a second packaging film 32, since the second packaging film 32 is made of an unstretched film, the exposure of the antioxidant on the surface of the second packaging film 32 is suppressed compared to the stretched film 3a. Therefore, it is possible to suppress the yellowing of the soap 2 caused by the antioxidant contained in the second packaging film 32 coming into contact with the licorice extract contained in the soap 2. Therefore, it is possible to provide a soap product 1 in which the yellowing of the soap 2 packaged with the second packaging film 32 is suppressed.

[0061] (3A) In the soap product 1 in which the soap 2 is packaged in a third packaging film 33, the third packaging film 33 is provided with an outer layer 3o containing an antioxidant and an inner layer 3i not containing an antioxidant, so that the inner layer 3i can prevent direct contact between the outer layer 3o and the soap 2. In this way, contact between the licorice extract contained in the soap 2 and the antioxidant contained in the outer layer 3o of the third packaging film 33 can be avoided. Therefore, it is possible to provide a soap product 1 in which the yellowing of the soap 2 packaged with the third packaging film 33 is suppressed.

[0062] (4A) In the case of a soap product 1 in which a barrier film 4 is interposed between the soap 2 and the packaging film 3, the barrier film 4 structurally prevents direct contact between the packaging film 3 and the soap 2. Therefore, in the case of a soap product 1 in which the soap 2 is packaged with a packaging film 3 containing an antioxidant, such as the second packaging film 32 or the third packaging film 33, contact between the licorice extract contained in the soap 2 and the antioxidant contained in the packaging film 3 is prevented or suppressed. Thus, yellowing of the soap 2 due to contact between the licorice extract and the antioxidant can be suppressed.

[0063] Therefore, it is possible to provide a soap product 1 in which the yellowing of the soap 2, interposed between the barrier film 4 and the packaging film 3, is suppressed. Furthermore, in the case of soap product 1, which is provided with a barrier film 4 in addition to the packaging film 3 that does not contain antioxidants, such as the first packaging film 31, the soap 2 is packaged not only by the packaging film 3 but also by the barrier film 4, thereby enhancing the protective properties of the soap 2.

[0064] (5A) The first soap product 11, which is packaged in a folded-wrap type, and the second soap product 12, which is packaged in a pillow-wrap type, have a smaller contact area S between the packaging film 3 and the soap 2 than the third soap product, which is packaged in a stretch-wrap type. Specifically, the first contact area S1 between the packaging film 3 and the soap 2 in the first soap product 11, and the second contact area S2 between the packaging film 3 and the soap 2 in the second soap product 12, are smaller than the third contact area S3 between the packaging film 3 and the soap 2 in the third soap product.

[0065] As described above, in the first soap product 11 and the second soap product 12, in which the contact area of ​​the packaging film 3 with the soap 2 is reduced, the contact area between the licorice extract contained in the soap 2 and the antioxidant contained in the packaging film 3 is suppressed. Therefore, in soap product 1 in which the soap 2 is packaged with a packaging film 3 containing an antioxidant, such as the second packaging film 32 and the third packaging film 33, contact between the licorice extract contained in the soap 2 and the antioxidant contained in the packaging film 3 is prevented or suppressed. Consequently, yellowing of the soap 2 due to contact between the licorice extract and the antioxidant can be suppressed. Therefore, it is possible to provide a soap product 1 in which the yellowing of the soap 2 packaged in the packaging film 3 is suppressed.

[0066] (6A) In the case of the first soap product 11 packaged in a double-wrap type, if the double-wrap type provides more loose packaging than the pillow-type type, the area S in contact with the soap 2 by the packaging film 3 can be reduced compared to the second soap product 12 packaged in a pillow-type type (i.e., the inequality "second area S2 > first area S1" holds). In such cases, the contact area between the licorice extract contained in the soap 2 and the antioxidant contained in the packaging film 3 is further reduced, and yellowing of the soap 2 due to contact between the licorice extract and the antioxidant can be further suppressed in the first soap product 11.

[0067] (7A) In the case of the second soap product 12 packaged in a pillow-type packaging, if the pillow-type packaging is more loosely packaged than the overlapping-wrap type packaging, the area S in contact with the soap 2 by the packaging film 3 is smaller than that of the first soap product 11 packaged in an overlapping-wrap type (i.e., the inequality "first area S1 > second area S2" holds). In such cases, the contact area between the licorice extract contained in the soap 2 and the antioxidant contained in the packaging film 3 is further suppressed, and yellowing of the soap 2 due to contact between the licorice extract and the antioxidant can be further suppressed in the second soap product 12.

[0068] [3-2. Method for Manufacturing Soap Products] (1B) In the soap product manufacturing method in which the first packaging film 31 is prepared in the preparation step, the first packaging film 31 that does not contain antioxidants is prepared. As a result, it is possible to manufacture a soap product 1 that, in principle, avoids the yellowing of the soap 2 caused by the antioxidant coming into contact with the licorice extract contained in the soap 2. Therefore, it is possible to provide a soap product 1 in which the yellowing of the soap 2 packaged with the first packaging film 31 is suppressed.

[0069] (2B) In the soap product manufacturing method in which the second packaging film 32 is prepared in the preparation step, the second packaging film 32 is made of an unstretched film. As a result, the exposure of the antioxidant on the surface of the second packaging film 32 is suppressed compared to the stretched film 3a. Therefore, it is possible to manufacture a soap product 1 in which yellowing of the soap 2 caused by contact between the licorice extract contained in the soap 2 and the antioxidant contained in the second packaging film 32 is suppressed. Therefore, it is possible to provide a soap product 1 in which the yellowing of the soap 2 packaged with the second packaging film 32 is suppressed.

[0070] (3B) In a soap product manufacturing method in which a third packaging film 33 is prepared in the preparation step, a multilayer third packaging film 33 is prepared. Since the third packaging film 33 is provided with an outer layer 3o containing an antioxidant and an inner layer 3i not containing an antioxidant, in the soap product 1 in which the soap 2 is packaged with the third packaging film 33 prepared in the preparation step, the inner layer 3i can prevent the outer layer 3o from coming into direct contact with the soap 2. In this way, a soap product 1 can be manufactured in which contact between the licorice extract contained in the soap 2 and the antioxidant contained in the outer layer 3o of the third packaging film 33 can be avoided. Therefore, it is possible to provide a soap product 1 in which the yellowing of the soap 2 packaged with the third packaging film 33 is suppressed.

[0071] (4B) In a soap product manufacturing method in which a barrier film 4 is interposed between the packaging film 3 and the soap 2 during the interposition process, a soap product 1 can be manufactured in which direct contact between the packaging film 3 and the soap 2 is structurally prevented. Therefore, when a packaging film 3 containing an antioxidant, such as a second packaging film 32 or a third packaging film 33, is prepared in the preparation process, contact between the licorice extract contained in the soap 2 and the antioxidant contained in the packaging film 3 is prevented or suppressed. Thus, yellowing of the soap 2 due to contact between the licorice extract and the antioxidant can be suppressed. Therefore, it is possible to provide a soap product 1 in which the yellowing of the soap 2, interposed between the barrier film 4 and the packaging film 3, is suppressed.

[0072] (5B) According to a soap product manufacturing method in which the soap 2 is packaged by a packaging film 3 in a folded-wrap type or pillow-wrap type during the packaging process, it is possible to manufacture first soap products 11 and second soap products 12 in which the area S in contact with the soap 2 by the packaging film 3 is smaller than that of third soap products packaged in a stretch-wrap type. As described above, with the first soap product 11 and the second soap product 12, in which the contact area of ​​the packaging film 3 with the soap 2 is reduced, the contact area between the licorice extract contained in the soap 2 and the antioxidant contained in the packaging film 3 is suppressed. Therefore, it is possible to suppress the yellowing of the soap 2, which is packaged with a packaging film 3 containing an antioxidant and also contains licorice extract, as in the second packaging film 32 and the third packaging film 33. Therefore, it is possible to provide a soap product 1 in which the yellowing of the soap 2 packaged in the packaging film 3 is suppressed.

[0073] (6B) In a soap product manufacturing method in which the soap 2 is packaged by a packaging film 3 in a double-wrap type form during the packaging process, if the double-wrap type form provides more loose packaging than the pillow-type form, then a first soap product 11 can be manufactured in which the area S in contact with the soap 2 by the packaging film 3 is smaller than that of a second soap product 12 packaged in a pillow-type form (i.e., the inequality "second area S2 > first area S1" holds). In such a case, the contact area between the licorice extract contained in the soap 2 and the antioxidant contained in the packaging film 3 is further suppressed. Therefore, yellowing of the soap 2 due to contact between the licorice extract and the antioxidant can be further suppressed in the first soap product 11.

[0074] (7B) In a method for manufacturing soap products in which soap 2 is packaged in a pillow-type packaging form by a packaging film 3 during the packaging process, if the pillow-type packaging is more loosely packaged than the overlap-wrap type, a second soap product 12 can be manufactured in which the area S in contact with the soap 2 by the packaging film 3 is smaller than that of the first soap product 11 packaged in the overlap-wrap type (i.e., the inequality "first area S1 > second area S2" holds). In such a case, the contact area between the licorice extract contained in the soap 2 and the antioxidant contained in the packaging film 3 is further suppressed. Therefore, yellowing of the soap 2 due to contact between the licorice extract and the antioxidant can be further suppressed in the second soap product 12.

[0075] (8B) In a soap product manufacturing method in which the soap 2 is molded by pressing the base material into a predetermined outer shape with a mold without performing a pattern molding process in the molding process, the soap 2 is molded without performing a pattern molding process. As a result, the area around the pattern, which is slightly indented due to being pressed by the insert, is not molded in principle, and no step is created at the boundary between the area around the pattern and the gap area in principle. Therefore, even if the base material of the soap 2 contains moisture, that moisture can be squeezed out or seeped out during the pattern molding process, and it is possible to suppress the adhesion of moisture to the surface of the soap 2. As moisture adhering to the surface of the soap 2 is suppressed in this way, it is possible to manufacture a soap product 1 in which yellowing of the soap 2 due to the elution of licorice extract into the moisture adhering to the surface of the soap 2 is suppressed. Therefore, it is possible to provide a soap product 1 in which the yellowing of the soap 2 packaged in the packaging film 3 is suppressed.

[0076] (9B) In a soap product manufacturing method in which a base molding process and a pattern molding process are carried out in the molding process, only the pattern region which is molded into a fine nested pattern 2P is pressed in the pattern molding process. As a result, in principle, it is possible to avoid the occurrence of the above-mentioned step difference in the region between the master mold which molds the base material into the general shape of the soap 2 and the pattern region (hereinafter referred to as the "intermediate region"). Furthermore, since only the pattern region is pressed in the pattern molding process, the intermediate region is not pressed in the molding process, and even if the base material contains moisture, that moisture is less likely to be squeezed out into the intermediate region, thereby suppressing the adhesion of moisture to the surface of the soap 2. As moisture adhering to the surface of the soap 2 is suppressed in this way, it is possible to manufacture a soap product 1 in which yellowing of the soap 2 due to the elution of licorice extract into the moisture adhering to the surface of the soap 2 is suppressed. Therefore, it is possible to provide a soap product 1 in which the yellowing of the soap 2 packaged in the packaging film 3 is suppressed.

[0077] (10B) Furthermore, in a soap product manufacturing method in which a mold wiping step is performed, moisture adhering to the mold used to mold the soap 2 is wiped away in the mold wiping step. Therefore, even if moisture is adhering to the mold, that moisture is wiped away by the mold wiping step. As a result, any moisture that could transfer from the mold to the base material of the soap 2 (and thus to the molded soap 2) is wiped away. In this way, moisture adhering to the surface of the soap 2 is suppressed, making it possible to manufacture a soap product 1 in which yellowing of the soap 2 due to the elution of licorice extract into the moisture adhering to the surface of the soap 2 is suppressed. Therefore, it is possible to provide a soap product 1 in which the yellowing of the soap 2 packaged in the packaging film 3 is suppressed.

[0078] (11B) In the soap product manufacturing method in which the removal step is performed, the moisture adhering to the surface of the molded soap 2 is removed in the removal step, thereby suppressing the adhesion of moisture to the surface of the molded soap 2. In this way, a soap product 1 can be manufactured in which yellowing of the soap 2 due to the dissolution of licorice extract into the moisture adhering to the surface of the soap 2 is suppressed. Therefore, it is possible to provide a soap product 1 in which the yellowing of the soap 2 packaged in the packaging film 3 is suppressed.

[0079] [II. Variant Examples] The embodiments described above are merely illustrative, and there is no intention to exclude various modifications or applications of techniques not explicitly stated in these embodiments. Each configuration of these embodiments can be modified in various ways without departing from their spirit. Furthermore, they can be selected and combined as needed.

[0080] For example, in a soap product manufacturing method, a base molding process is performed, and a pattern molding process is performed in which not only the pattern area but also the area surrounding the pattern is pressed to create a recess in the pattern, as in the conventional method. In addition, an interfacing process may be performed, and a mold wiping process or removal process may also be performed. With such a soap product manufacturing method, a slight step is created at the boundary between the area surrounding the pattern, which is slightly recessed by being pressed by the insert during the pattern molding process, and the gap area that is not pressed by the insert.

[0081] In contrast, when an intervening process is performed, the barrier film can prevent or suppress contact between moisture accumulated in the step and the packaging film. In this way, even if moisture adheres to the surface of the molded soap, the barrier film is interposed between the moisture and the packaging film, making it possible to manufacture soap products that suppress yellowing of the soap due to the leaching of licorice extract into the moisture adhering to the soap's surface. Furthermore, when a mold wiping process or removal process is performed, the mold wiping process removes moisture adhering to the mold, and the removal process removes moisture adhering to the soap's surface, thereby suppressing the accumulation of moisture in the slight step at the boundary between the pattern peripheral area and the gap area. In this way, it is possible to suppress moisture adhering to the surface of the molded soap, making it possible to manufacture soap products that suppress yellowing of the soap due to the leaching of licorice extract into the moisture adhering to the soap's surface.

[0082] On the other hand, the mold wiping and removal steps may be omitted from the soap product manufacturing method. In this case, soap products can be manufactured with a simpler configuration. Furthermore, the soap product may include a soap with a slight step at the boundary between the patterned area and the gap area, as in conventional products, and a barrier film may be interposed between the soap and the packaging film. Furthermore, the licorice extract contained in the soap is not limited to water-soluble; various types with different properties may be used. Similarly, the antioxidant contained in the packaging film is not limited to lipophilic; various types with different properties can be used.
