Description

  The present invention relates to a container for viscous cosmetics in which a storage unit for storing viscous cosmetics is provided, and an application body formed of an elastic body is connected to the tip of the storage unit.

Conventionally, there is a viscous cosmetic container in which a viscous cosmetic material such as lip gloss is stored in a cylindrical or tube-shaped storage unit, and an application body is connected to the tip of the storage unit. Such a container for viscous cosmetics forms a dispensing port for discharging the viscous cosmetic material to the application body, and discharges the viscous cosmetic material in the storage part little by little outwardly from the dispensing port. It is applied to the application part.
JP-A-10-192050

  However, in the conventional viscous cosmetic container as described above, when the area of the dispensing port is extremely large with respect to the area of the application surface, the dispensing port is applied when the viscous cosmetic is applied to the coated portion such as the lips. This is likely to remain on the coated part, and the tactile feeling of the coated surface in the coated part is deteriorated. In addition, when the area of the dispensing port is extremely small with respect to the area of the application surface, when the viscous cosmetic material is discharged, the viscous cosmetic material does not discharge flatly on the application surface and is perpendicular to the application surface. It becomes easy to discharge in the direction. Therefore, when the coated surface is brought into contact with the coated part such as the lips, the viscous cosmetic material concentrates and adheres to a certain point of the coated part, resulting in uneven coating on the coated part such as the lips. It becomes easy

  Moreover, when the container for viscous cosmetics described in Patent Document 1 is used, after the user discharges an appropriate amount of viscous cosmetic material by the discharge operation and performs the application operation, the viscosity is continuously discharged from the distribution port. There may be a so-called after-draw phenomenon in which cosmetics continue to be discharged.

    And when the area of a distribution port is extremely small with respect to the area of an application surface, it becomes easy to discharge a lot of viscous cosmetics by the said after-draw phenomenon. In this way, when a large amount of viscous cosmetic material is discharged due to the after-draw phenomenon, the excess viscous cosmetic material is consumed in large amounts, resulting in poor economic efficiency. In addition, since a large amount of discharged viscous cosmetics adheres to the application surface, it takes time to wipe off the viscous cosmetics after use, and if the wiping operation is not performed sufficiently, the viscous cosmetics are applied onto the application surface. Since the material remains, a problem arises in terms of hygiene.

    Further, in the viscous cosmetic container as described in Patent Document 1, when the viscous cosmetic material having extremely high hardness is used, when discharging the viscous cosmetic material, the resistance of the discharge operation of the viscous cosmetic container is Since the feeling becomes large, it becomes difficult to smoothly perform the viscous cosmetic discharge operation. In addition, when using a viscous cosmetic material with extremely low hardness, when the application body passes through the application part such as the lips during the application work, the stripes due to the application object are easily formed on the application part, The finish of the makeup is poor.

  Accordingly, the present invention is intended to solve the above-described problems, and can smoothly perform the discharge operation and the application operation to the application portion, and the touch feeling of the application body in the application portion is good. It is possible to obtain a container for viscous cosmetics that can be made and have a good finish after application.

  In order to solve the above-described problems, the present invention provides an application body at one end of a cylindrical or tube-shaped storage portion in which the viscous cosmetic is stored, and the storage surface is formed on the application surface formed at the tip of the application body. A dispensing port communicating with the portion is formed, and the viscous cosmetic in the storage portion can be discharged outward from the dispensing port.

    And while setting the area ratio of a distribution port and an application surface to 0.04: 1-0.07: 1, the hardness of the said viscous cosmetics is 3-50. The hardness of the present invention means a hardness measured by a rheometer (RHEOTECH FUDOH RHEO METER RTC-2002D.D diameter 11.3 mm, 3 mm needle holder) in an atmosphere of 25 ° C.

    And when the area of an application surface is set to 1, and the area of a distribution port is smaller than 0.04, a viscous cosmetic does not discharge on a coating surface planarly, but is perpendicular | vertical with respect to an application surface. In the direction, it becomes easy to discharge in the shape of a so-called bamboo shoot. In this way, when the viscous cosmetic is discharged in the shape of a bamboo shoot, when the application surface is brought into contact with the application part such as the lips, the viscous cosmetic concentrates as a lump at a certain point on the application part. Will adhere. For this reason, uneven coating tends to occur in the coated portion, and it becomes difficult to uniformly apply the viscous cosmetic material to the coated portion such as the lips, and the coating work becomes complicated.

  Moreover, a large amount of viscous cosmetics can be easily discharged by the after-draw phenomenon. Therefore, the excess viscous cosmetics are consumed in a large amount, resulting in poor economic efficiency, and a large amount of the viscous cosmetics discharged adheres to the application surface, which requires time and effort for wiping off the viscous cosmetics after use. In addition, when the wiping operation is not sufficiently performed, the viscous cosmetic material remains on the coated surface, which causes a problem in terms of hygiene.

    Further, when the area of the application surface is 1, and the area of the distribution port is larger than 0.07, the area of the distribution port becomes extremely larger than the area of the application surface. The feel of the dispensing mouth tends to remain in the coated part such as the lips. Therefore, when the application surface is brought into contact with the application portion during application, the feel of the application surface at the application portion is poor.

  Further, when the hardness of the viscous cosmetic is less than 3, when the applied body passes through the coated portion such as the lips during the coating operation, streaks due to the coated body are easily formed on the coated portion. The finish of becomes worse. On the other hand, when the viscosity of the viscous cosmetic material is greater than 50, when the viscous cosmetic material is discharged, the resistance of the discharge operation of the viscous cosmetic container becomes large, so the discharging operation should be performed smoothly. It becomes difficult.

    Therefore, in the present invention, since the area ratio between the distribution port and the application surface is 0.04: 1 to 0.07: 1 as described above, the viscous cosmetic material is planarly applied along the application surface from the distribution port during the discharge operation. Can be discharged. Accordingly, uneven coating is less likely to occur in the coated portion such as the lips, and it becomes easy to uniformly apply the viscous cosmetic to the coated portion. In addition, it is possible to improve the feel of the coated surface in the portion to be coated without feeling the feel of the distribution port during the coating operation. In addition, since it is possible to reduce the discharge of excess viscous cosmetics due to the after-draw phenomenon, it is possible to use it economically, and it is easy to wipe off and it is difficult for the viscous cosmetics to remain on the coated surface. , Hygiene problems are less likely to occur.

    Further, since the hardness of the viscous cosmetic material is 3 to 50, when the applied body passes through the coated portion such as the lips during the coating operation, the streaks due to the coated body are difficult to be formed on the coated portion. It is possible to improve the finish of the. In addition, when the viscous cosmetic is discharged, it is possible to reduce the resistance to the discharge operation of the viscous cosmetic container, and thus it is possible to smoothly discharge the viscous cosmetic.

  Further, the application body may be formed separately from the storage section and connected to one end of the storage section, or may be formed integrally with the storage section at one end of the storage section. . When the application body is formed separately from the storage section, the application body material can be formed of a material different from the storage section material. For example, the application body is formed of an elastic material. By doing so, when the application body is brought into contact with the application portion such as the lips, it is possible to improve the feel of the application body in the application portion. In addition, when the application body is integrally formed at one end of the storage portion, it is not necessary to form the application body separately from the storage portion, the number of parts can be reduced, and the assembly work of the application body to the storage portion can be reduced. Since it becomes unnecessary, manufacturing can be facilitated.

  The present invention is configured as described above, and since the area ratio between the distribution port and the application surface is 0.04: 1 to 0.07: 1, the viscous cosmetic is planarly formed along the application surface. It becomes possible to discharge, and uneven coating is less likely to occur, making it easy to uniformly apply the viscous cosmetic material to the application portion. In addition, it is difficult for the feel of the distribution port to remain, and it becomes possible to improve the feel of the coated surface in the coated portion. In addition, since it is possible to reduce discharge of excess viscous cosmetics due to the after-draw phenomenon, it is possible to use economically, and it is difficult for viscous cosmetics to remain on the coated surface, which is a sanitary problem. Is less likely to occur.

    Further, since the hardness of the viscous cosmetic material is 3 to 50, when the applied body passes through the coated portion such as the lips during the coating operation, the streaks due to the coated body are difficult to be formed on the coated portion. It is possible to improve the finish of the. Further, when discharging the viscous cosmetic, it is possible to reduce the resistance feeling of the discharge operation of the viscous cosmetic container, so that the discharge operation can be performed smoothly.

  An embodiment of the present invention will be described with reference to FIG. 1. (1) is an application body made of an elastic material, and is connected to the upper end of a storage section (3) that stores a viscous cosmetic (2). Further, the storage part (3) is provided with an extrusion mechanism (4) for pressing the viscous cosmetic (2) stored inside in the direction of the application body (1).

    The viscous cosmetic container according to the present embodiment will be described in detail below. The application surface (1) is formed into an elliptical shape at the tip of the application body (1) and is inclined with respect to the axial direction of the application body (1) ( 5). By forming the application surface (5) in this manner, when the viscous cosmetic container is supported with the application surface (5) facing upward, the application surface (5) can be easily applied to the application part such as the lips. It is possible to make them face each other.

    In this embodiment, the coating surface (5) is formed so as to protrude outward in an arc shape as shown in FIG. By forming the application surface (5) in a protruding manner in this way, the contact area between the application surface (5) and the portion to be applied becomes small, so the soft elasticity of the application body (1) made of an elastic material is achieved. It becomes easy to be transmitted to the portion to be coated, and the feel of the portion to be coated at the time of coating can be made favorable.

  In this embodiment, the application body (1) is formed of an elastic material as described above. However, in another different embodiment, the application body (1) can be formed of a hard material. In this embodiment, the application body (1) formed separately from the storage section (3) is connected to one end of the storage section (3). It is also possible to form the application body (1) integrally with the storage part (3) at one end of (3). In this case, since it is not necessary to form the application body (1) separately from the storage section (3), the number of parts can be reduced and the assembling work of the application body (1) to the storage section (3) Is not necessary, and thus the manufacturing can be facilitated.

    Moreover, as shown in FIG. 1, the distribution port (9) of the viscous cosmetics (2) is formed in one place at the center of the application surface (5). And the flow path (6) of the viscous cosmetics (2) is formed in the axial direction of the application body (1) continuously to the distribution port (9). Further, a lower end fitting hole (7) is formed in the lower end side of the application body (1) so as to be continuous with the flow passage (6). In this embodiment, the distribution port (9) and the flow passage (6) are formed only in one place in the application body (1). However, in other different embodiments, the distribution port (9) and the flow passage ( It is also possible to form a plurality of 6) on the coated body (1).

  Then, as described above, the upper end fitting portion (8) protruding from the upper end of the storage portion (3) is fitted into the lower end fitting hole (7) formed in the application body (1) as described above. The formed application body (1) is connected to the upper end of the storage part (3). The storage portion (3) is formed of a cylindrical tube (10), and a storage portion main body (11) storing the viscous cosmetic (2) is provided in the center. . In addition, on the side opposite to the application body (1) connection side of the storage section (3), an extrusion mechanism for pressing the viscous cosmetic (2) in the storage section main body (11) toward the application body (1) side. (4) is provided.

  And the upper end fitting part (8) of the accommodating part (3) formed as mentioned above is formed in a cylindrical shape, and this upper end fitting part (8) is made into the lower end fitting hole (7) of the said application body (1). Is fitted. Thereby, the inside of the storage unit body (11) and the flow path (6) of the application body (1) communicate with each other, and the viscous cosmetic material (2) in the storage unit body (11) is connected to the flow path (6). It becomes possible to discharge onto the coating surface (5).

    Next, the extrusion mechanism (4) will be described in detail below. A cylindrical holding member (13) is fixedly arranged on the inner periphery on the lower end side of the storage portion (3). A cylindrical holding portion (14) is fixedly disposed inside the holding member (13), and an inner circumferential screw groove (15) is formed on the inner periphery of the holding portion (14). The outer peripheral surface of the rotary shaft (12) is formed by connecting the outer peripheral screw groove (16) that can be screwed into the inner peripheral screw groove (15) of the holding portion (14) to the upper end of the rod (17). The rotating shaft (12) is screwed onto the holding portion (14).

    As described above, the rotating shaft (12) is screwed into the holding portion (14) fixedly arranged on the inner periphery of the cylindrical body (10), so that the rotating shaft (12) is located on the lower end side of the storage portion (3). It is located in the axial direction. Then, as shown in FIG. 1, an engaging protrusion (18) is provided at the upper end of the rotating shaft (12) and is engaged with the engaging protrusion (18) on the bottom surface of the inner tray (17). A possible engagement recess (20) is formed. Then, the engaging projection (18) of the rotating shaft (12) is made to engage with the engaging recess of the inner plate (17) so that the rotating shaft (12) can rotate independently of the inner plate (17). (20) is engaged. The rotating shaft (12) has an elliptical cross-sectional shape.

    An inner cylinder (21) is disposed below the holding portion (14) on the inner periphery of the holding member (13). The inner cylinder (21) is formed in a cylindrical shape, and as shown in FIG. 1, a top plate (22) is provided at the upper end, and the lower end side is more outward than the lower end of the cylinder (10). A projecting portion (19) is provided so as to project. An insertion hole (23) for inserting the rotating shaft (12) is provided at the center of the top plate (22).

    The insertion hole (23) has an elliptical shape corresponding to the cross-sectional shape of the rotating shaft (12) and is slightly larger than the outer diameter of the rotating shaft (12). By forming the insertion hole (23) in this way, the rotation shaft (12) can be rotated integrally with the inner cylinder (21) by inserting the rotation shaft (12) through the insertion hole (23). In addition, it is slidable in the vertical direction independently of the inner cylinder (21).

  An annular engaging groove (24) is formed on the outer periphery of the inner cylinder (21), and an annular protrusion (25) that can be engaged with the engaging groove (24) is provided with a holding member. Projecting at the inner periphery of the lower end of (13). Then, by engaging the annular protrusion (25) of the holding member (13) with the engaging groove (24) of the inner cylinder (21), the inner cylinder (21) is removed from the holding member (13). It is impossible to detach and is assembled so as to be rotatable independently of the holding member (13).

  Further, an abutting step portion (26) is provided below the engaging groove (24), and the lower end surface of the holding member (13) is abutted against the abutting step portion (26). In addition, on the outer periphery of the projecting portion (19) of the inner cylinder (21), a cylindrical rotating body (27) having a U-shaped cross section is connected and fixed to the projecting portion (19). And the upper end surface of this rotation body (27) is made to contact | abut to the lower end surface of a cylinder (10).

    Further, a cylindrical lid (28) capable of covering the application body (1) is detachably connected to the upper end of the cylindrical body (10). When not in use, the lid (28) Is connected to the upper end of the storage part (3), so that the application body (1) can be covered and contact with the outside air can be blocked. For this reason, the viscous cosmetic (2) can be prevented from being deteriorated by contact with the outside air, and the applied body (1) and the viscous cosmetic ( It becomes possible to prevent the contamination of 2).

    In the configuration as described above, the discharge mechanism of the viscous cosmetic (2) will be described in detail below. First, the viscous cosmetic material (2) is filled into the interior of the storage unit body (11). The prescription for the viscous cosmetic (2) will be described in detail below. Then, the lid (28) connected to the cylinder (10) is removed, and the rotating part (27) provided at the lower end of the receiving part (3) in a state where the receiving part (3) is held and fixed by hand. ) In one direction. Thereby, the inner cylinder (21) to which the rotating body (27) is fixed also rotates in one direction integrally with the rotation of the rotating body (27). As a result, the rotation shaft (12) inserted through the insertion hole (23) of the inner cylinder (21) rotates together with the inner cylinder (21), and is rotated by the inner circumferential groove (15) of the holding portion (14). It will be sent to the application body (1) side while moving.

    And since the inner tray (17) connected to the upper end of the rotation shaft (12) is pressed toward the application body (1) by the movement of the rotation shaft (12) toward the application body (1), The inner tray (17) slides inside the storage portion (3) toward the application body (1). As described above, since the rotation shaft (12) is assembled so as to be rotatable independently of the middle plate (17), the middle plate (17) does not rotate and moves inside the storage portion (3). Slide in the direction of the coated body (1). The viscous cosmetic (2) in the storage body (11) is pressed in the direction of the application body (1) by sliding the inner tray (17) toward the application body (1). Thereby, the viscous cosmetic material (2) in the storage unit body (11) is fed into the flow path (6) of the application body (1) through the upper end fitting portion (8).

  The viscous cosmetic material (2) that has been pressed by the intermediate tray (17) and passed through the flow passage (6) of the application body (1) as described above is removed from the distribution port (9) of the application surface (5). To be discharged. Accordingly, by appropriately rotating the rotating body (27), a desired amount of the viscous cosmetic (2) is discharged from the distribution port (9), and the viscous cosmetic (2) is applied to the application portion. Can be done.

  Then, as shown in Table 1, each of the viscous cosmetic containers formed as described above and the application bodies (1) having different area ratios of the distribution port (9) and the application surface (5) are respectively examples of the present invention. 1-3. That is, as shown in Table 1, the area ratio between the distribution port (9) and the coating surface (5) is 0.04: 1 in Example 1, 0.06: 1 in Example 2, and further in Example 3. It was set to 0.063: 1.

  Further, as a comparative example of the present invention, the viscous cosmetic container is formed as described above, and the ratio of the area of the distribution port (9) to the application surface (5) is smaller than that of Example 1, Comparative Example 1 with an area ratio of the mouth (9) to the coated surface (5) of 0.01: 1, Comparative Example 2 with 0.02: 1, Comparative Example 3 with 0.025: 1 It was. Further, the ratio of the area of the distribution port (9) to the application surface (5) is larger than that of Example 3, and the area ratio of the distribution port (9) to the application surface (5) is 0.09: 1. Comparative Example 4 and 0.12: 1 were used as Comparative Example 5.

  Then, when the viscous cosmetic (2) is discharged from the distribution port (9), the discharge state of how the viscous cosmetic (2) is discharged onto the application surface (5) is set for each implementation. Each example and comparative example was confirmed visually. In the above confirmation experiment, the same viscous cosmetic material (2) was used, and its hardness was 15 at 25 ° C.

    As a result, as shown in Table 1, in Examples 1 to 3 and Comparative Examples 4 and 5, the viscous cosmetic (2) spreads in a plane along the application surface (5) during discharge. As described above, the viscous cosmetic (2) spreads in a plane on the application surface (5), so that when the application surface (5) is brought into contact with the application part such as lips, the application surface (5) Apply the viscous cosmetic (2) evenly on the surface to be coated (5) because the viscous cosmetic (2) spread on the surface is easy to adhere to a wide area without concentrating on one point. Becomes easy. Therefore, the application work can be performed smoothly.

    On the other hand, in Comparative Examples 1 to 3, the viscous cosmetic material was ejected in a so-called “bamboo shape” in the direction perpendicular to the application surface during ejection. Therefore, when the coated surface is brought into contact with the coated portion, the viscous cosmetic material on the coated surface becomes a lump and is concentrated and adhered to a certain point on the coated surface. Therefore, it becomes difficult to uniformly apply the viscous cosmetic material to the surface to be applied, and the application work becomes complicated.

  From the above results, when the area of the application surface (5) is 1, and the area of the dispensing port (9) is 0.04 or more, the viscous cosmetic (2) is placed on the application surface (5). It was confirmed that it was possible to perform the coating operation smoothly because it spreads and discharges. On the other hand, when the area of the dispensing port (9) is smaller than 0.04 when the area of the application surface (5) is 1, the viscous cosmetic (2) is easy to discharge in a so-called “bamboo shoot” Thus, it became clear that it is difficult to uniformly apply the viscous cosmetic (2) to the surface to be coated.

  Next, when the viscous cosmetic material (2) is applied to the lip which is the application portion using the application bodies (1) of Examples 1 to 3 and Comparative Examples 1 to 5, the dispensing port (9) A sensory test was conducted for the presence or absence of the touch of the holes. This sensory test was carried out by three subjects, and in a temperature-controlled room at 25 ° C., the viscous cosmetic material (2) was applied once to each of the upper lip and lower lip of the subject. The touch of the coated surface (5), that is, the presence or absence of the hole in the distribution port (9) was evaluated. As a result, as shown in Table 1, in Examples 1 to 3 and Comparative Examples 1 to 3, the feel of the hole of the distribution port (9) was not felt, whereas in Comparative Examples 4 and 5, As a result, the feel of the hole of the distribution port (9) was felt on the coated surface.

    From the above results, when the area of the application surface (5) is 1, and the area of the distribution port (9) is 0.07 or less, the hole of the distribution port (9) is formed in the application portion during application. Thus, it has been clarified that the touch of the coated surface (5) becomes smooth and the touch can be improved. On the other hand, when the area of the dispensing port (9) is larger than 0.07 when the area of the coating surface (5) is 1, the feel of the hole of the dispensing port (9) is felt during coating. It became clear that the feeling of the coated surface (5) in the part was poor.

    Further, in the viscous cosmetic container as in the present invention, after the user discharges an appropriate amount of the viscous cosmetic (2) by the discharge operation and performs the application operation, the viscous makeup continues from the dispensing port (9). There may be a so-called after-draw phenomenon in which the material (2) continues to discharge.

    When a large amount of viscous cosmetic (2) is discharged due to this after-draw phenomenon, the excess viscous cosmetic (2) is consumed in large amounts, resulting in poor economic efficiency. Moreover, since a large amount of the viscous cosmetic material (2) discharged adheres to the application surface (5), the wiping work for the viscous cosmetic material (2) after use is troublesome and not sufficiently performed. In this case, since the viscous cosmetic material (2) remains on the coated surface (5), a problem arises in terms of hygiene.

  Therefore, for Examples 1 to 3 of the present invention, the discharge amount of the viscous cosmetic material (2) discharged by the after-draw phenomenon was measured. The discharge amount measurement experiment will be described below. First, the container (3) was filled with the viscous cosmetic (2). And the container for viscous cosmetics was left to stand in a 5 degreeC thermostat in this state for 6 hours or more. Then, immediately after taking out the container for viscous cosmetics from the said thermostat, the rotating body (27) of the said container for viscous cosmetics was rotated 180 degreeC vigorously in the discharge direction of the viscous cosmetics (2).

  By this rotation, the viscous cosmetic material (2) in the storage section (3) is discharged from the dispensing port (9) onto the application surface (5), and thus the discharged viscous cosmetic material (2) is immediately wiped off. Left for a minute. Then, during this 1-minute standing, an after-draw phenomenon occurred in which the viscous cosmetic material (2) in the storage section (3) gradually discharged from the distribution port (9). And the viscous cosmetics (2) discharged by this after-draw phenomenon was extract | collected, the weight was measured, and the weight was defined as the amount of after-draw in the present Example. In addition, in the measurement of the amount of after-drawing, it experimented using the viscous cosmetics (2) whose hardness range is 20-40.

  And as a result of having experimented about each Example and the comparative example as mentioned above, as shown in Table 1, in Example 1, the amount of after-draw was 0.02g-0.025g, in Example 2, 0.01g-0.02g, In Example 3, it was 0.02g-0.024g. On the other hand, in Comparative Examples 1 to 3, the afterdraw amount was 0.04 to 0.05 g, and in Comparative Examples 4 and 5, 0.01 to 0.02 g.

    In addition, in each said experimental result, the afterdraw amount in each Example and a comparative example is shown by the numerical range instead of a fixed numerical value. This is because the after-draw amount measurement experiment was performed three times under the same temperature condition for each example and each comparative example, and the measurement results were somewhat varied.

  From the above results, when the ratio of the area of the distribution port (9) to the area 1 of the coating surface (5) is 0.04 or more as in Examples 1 to 3 and Comparative Examples 4 and 5, the after sales It was confirmed that the draw amount can be suppressed to 0.025 g or less. On the other hand, when the ratio of the area of the distribution port (9) to the area 1 of the application surface (5) is smaller than 0.04 as in Comparative Examples 1 to 3, the amount of after-draw exceeds 0.025 g. Clearly increased. Therefore, when the viscous cosmetic container of Examples 1 to 3 is used, the amount of the viscous cosmetic (2) discharged by the after-draw phenomenon can be reduced, so that an unnecessary viscous cosmetic (2) is used. , And the sanitary condition of the coated surface (5) can be kept good.

    In the present embodiment, as described above, the viscous cosmetic container provided with the extrusion mechanism (4) is used. Therefore, if the discharge amount is small as described above, the rotating body of the viscous cosmetic container ( 27) is rotated in a direction opposite to the discharge direction to depressurize the inside of the storage unit main body (11), whereby the entire amount of the viscous cosmetic (2) discharged onto the application surface (5) is again applied to the application body (1). In some cases, it can be accommodated in the flow path (6).

  Next, in the viscous cosmetic containers of Example 1, Example 3, Comparative Example 1, and Comparative Example 2, a sensory test was performed for changes in the operational feel when the hardness of the viscous cosmetic (2) was different. The hardness of the present invention means a hardness measured by a rheometer (RHEOTECH FUDOH RHEO METER RTC-2002D.D diameter 11.3 mm, 3 mm needle holder) in an atmosphere of 25 ° C. Further, the operational feeling in the present embodiment means a sense of resistance felt when the rotating body (27) is rotated when the viscous cosmetic (2) is discharged in the viscous cosmetic container formed as described above. To do. And when there is little resistance of a rotation body (27), since a rotation body (27) can be rotated smoothly, it becomes possible to perform the discharge operation | work of a viscous cosmetics (2) smoothly. On the other hand, when the resistance of the rotating body (27) is large, it is difficult to smoothly rotate the rotating body (27).

    In the above sensory test, viscous cosmetics (2) having a hardness of 5, 22, 50, 67 are prepared, and these viscous cosmetics (2) are respectively used for the viscous cosmetic containers of the above examples and comparative examples. It accommodated in the accommodating part (3). The rotating body (27) of each Example and Comparative Example was rotated 90 degrees in the discharge direction to confirm the operational feel of the rotating body (27) when the viscous cosmetic material (2) was discharged. The confirmation method of the operation feeling will be described more specifically. First, after confirming the operation feeling in a 25 ° C. atmosphere, the operation feeling of the rotating body (27) in a 5 ° C. atmosphere was evaluated by sensory evaluation. The results of the sensory test are shown in Table 2 below.

  In Table 2, “◯” means “low sense of operating resistance”, “Δ” means “a little sense of operating resistance of discharge”, and “x” means “a feeling of high resistance of discharge”. As a result of the sensory test, from Table 2, in Example 1 and Example 3, when the viscosity of the viscous cosmetic material (2) is 50 or less, there is little ejection resistance feeling, but when the hardness is 67, it operates. As a result, the resistance was slightly increased.

    In this example, the case where the hardness of the viscous cosmetic material (2) is less than 5 has not been confirmed. However, from the above results, it is clear that when the hardness is less than 5, the operational resistance is reduced. From the above results, in Examples 1 and 3, particularly when the hardness of the viscous cosmetic material (2) is 50 or less, the rotating body (27) can be smoothly rotated during the discharging operation. However, if the hardness of the viscous cosmetic material (2) is less than 3, when the applied body (1) passes during the application operation, streaks are easily formed by the applied body (1), and the finish of the makeup is improved. Deteriorate.

  On the other hand, in Comparative Example 1 and Comparative Example 2, when the hardness of the viscous cosmetic material (2) is 5, the working resistance feeling of the rotating body (27) is small, but when the hardness is 22, the working resistance feeling is slightly large. Further, when the hardness was 50 and 67, the result was that the feeling of operating resistance was increased. From this result, when the area of the application surface (5) is 1, and the area of the dispensing port (9) is 0.02 or less, the resistance of the viscous cosmetic material (2) is 22 or more, and there is a feeling of operating resistance. It was confirmed that it would grow.

  In the first to third embodiments, the storage portion (3) is formed in a cylindrical shape and the extrusion mechanism (4) is provided inside. However, in other different embodiments, the extrusion mechanism is as in this embodiment. The storage part (3) may be formed in a tube shape without arranging (4). By forming the storage portion (3) into a tube shape in this way, the viscous cosmetic material (2) can be easily discharged by pressing with a finger without the need for the extrusion mechanism (4). Therefore, the configuration can be simplified, and a product that is easy to manufacture and low in cost can be obtained.
