Description

[Technical Field]

[0001] The present invention relates to a hair dye or hair bleach kit. [Background technology]

[0002] Conventionally, many hair dyes and hair bleaches have been filled in containers with a discharge port due to their convenience and ease of use, and in actual use, the agent is discharged from the discharge port to be applied to hair. Most of these agents are designed to be used up in one treatment to achieve the desired hair dyeing or bleaching effect, and discharge and application must be repeated during the treatment. Therefore, while applying the agent to hair, the container must be temporarily removed from hand, and the container is usually placed on a stand or the like in a stable position with the bottom of the container facing downward and the discharge port facing upward, i.e., in an upright position.

[0003] However, each time the container is placed upright, the contents tend to migrate to the bottom of the container and become concentrated near the bottom, so when the contents are discharged again, it takes an excessive amount of time for the contents to migrate to the discharge port. Furthermore, if the contents do not migrate to the discharge port on their own, it is necessary to apply an external force, such as shaking the container, to cause the contents to migrate, which poses a risk of the contents scattering when shaking the container, and also makes it difficult to smoothly discharge the entire amount of the contents, which may increase the burden on the user in treatments that involve repeated discharge and application.

[0004] In this context, for example, Patent Documents 1 and 2 disclose technologies that impart specific structures, shapes, functions, etc. to the container, the container body, and associated parts and components, assuming that the container will be used in an inverted state. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 7272724 [Patent Document 2] Japanese Patent Application Laid-Open No. 2008-273615 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the technology described in the above patent documents requires excessive effort and cost to impart a specific structure to a container, etc., and does not take into account the unique circumstances when the contents of the container are a hair dye or hair bleach, so further improvement is desired.

[0007] In other words, the present invention relates to a hair dye or hair bleach kit that has a simple structure and reduces the burden on the user while improving the efficiency of the treatment when using a hair dye or hair bleach, which requires repeated discharge and application. [Means for solving the problem]

[0008] The present inventors have conducted extensive research and have found that by providing a hair dye or bleach kit comprising a hair dye or bleach composition having a specific viscosity, a container for filling the hair dye or bleach composition with the composition, the container having a discharge part with a specific discharge port and a container body, and a specific support, the burden on the user during treatment, which requires repeating discharge and application while easily holding the container in an inverted position, can be reduced, leading to the completion of the present invention.

[0009] Therefore, the present invention provides a hair coloring or hair bleaching composition (A), a container (X) having a discharge part (x1) and a container body (x2) for filling the hair coloring or hair bleaching composition (A), and a support (Y) for holding the container (X), A hair dye or hair bleach kit, in which a container (X) is held on a support (Y) with a discharge part (x1) facing downward and a bottom surface of a container body (x2) facing upward, so that the container (X) is used in an inverted or tilted position, The viscosity of the hair coloring or hair bleaching composition (A) at 30°C is 600 mPa s or more and 50,000 mPa s or less, When the container (X) is in an inverted upright position, the angle θ between a vertical line passing through the center of gravity of the container body (x2) and a line passing through the center of gravity of the container body (x2) and the center of the bottom surface of the container body (x2) is 0°; When the container (X) is in an inverted, tilted position, the angle θ between a vertical line passing through the center of gravity of the container body (x2) and a line passing through the center of gravity of the container body (x2) and the center of the bottom surface of the container body (x2) is greater than 0° and less than or equal to 80°; The discharge part (x1) has one or more discharge ports with an inner diameter of 1.2 mm or more and 5 mm or less, The hair dye or hair bleach kit has a mechanism in which, when the support (Y) is placed on a horizontal plane and the container (X) is held on the support (Y) in an inverted or upside-down position, the intersection of a vertical line passing through the center of gravity of the container body (x2) and the horizontal plane on which the support (Y) is placed is located within a horizontal plane yz surrounded by the lowest end (y1-1) of the support (Y). [Effects of the Invention]

[0010] The hair dye kit and hair bleach kit of the present invention have a simple structure, yet can stably hold the inverted container during repeated dispensing and application, effectively reducing the burden on the user during treatment. Furthermore, the kit is not affected by the structure of the container itself, and is highly cost-effective and versatile. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0012] The present invention will be described in detail below with reference to the accompanying drawings. The hair color or hair bleach kit of the present invention comprises a hair color or hair bleach composition (A), a container (X) having a discharge part (x1) and a container body (x2) for filling with the hair color or hair bleach composition (A), and a support (Y) for holding the container (X).The container (X) is held on the support (Y) with the discharge part (x1) facing downward and the bottom of the container body (x2) facing upward, so that the container (X) can be used in an inverted or tilted position. That is, the hair color or hair bleach kit of the present invention (hereinafter, the hair color or hair bleach kit of the present invention will also be collectively referred to as the "kit of the present invention") enables efficient use, and as will be described later, the kit has a discharge part (x1) in the container (X) that has a discharge port with a specific inner diameter, and the support (Y) that has a specific mechanism, and can be used by filling it with a hair color or hair bleach composition (A) having a specific viscosity (hereinafter, the hair color or hair bleach composition (A) will also be collectively referred to as the "composition (A)").

[0013] As described above, the hair color or hair bleach kit of the present invention allows the container to be stably held in an inverted or tilted position during the treatment, which involves repeated dispensing and application, as is a usage mode specific to hair color or hair bleach, and allows the hair color or hair bleach composition contained therein to remain near the discharge port without migrating to the bottom of the container, while also effectively preventing unwanted leakage from the discharge port. Therefore, the treatment, which involves repeated dispensing and application, can be carried out efficiently without requiring an excessive amount of time, and the burden on the user can be effectively reduced. The kit of the present invention may be a hair color kit for coloring hair, in which case it may include composition (A) as a hair color composition. The kit of the present invention may also be a hair bleach kit for bleaching hair, in which case it may include composition (A) as a hair bleach composition. Furthermore, the kit of the present invention may be a hair color and hair bleach kit that can bleach and dye hair in one go, in which case it may include composition (A) as a hair color and hair bleach composition designed to bleach and dye hair with a single composition. The composition (A) may be in an embodiment containing one constituent agent, or in an embodiment containing a plurality of constituent agents, which are mixed together at the time of use to form a single composition.

[0014] The container (X) included in the kit of the present invention has a discharge part (x1) and a container body (x2), as shown in the schematic external view of Figure 1. The container (X) has a discharge part (x1) connected to the top opening of the container body (x2), has a bottom, and is a container to be filled with composition (A) as the content.

[0015] The discharge part (x1) has one or more discharge ports (x1-1) with an inner diameter of 1.2 mm or more and 5 mm or less, and may have two or more such discharge ports (x1-1). That is, even when the discharge part (x1) has one discharge port (x1-1), its inner diameter is 1.2 mm or more and 5 mm or less, and even when the discharge part (x1) has two or more discharge ports (x1-1), each inner diameter is 1.2 mm or more and 5 mm or less.

[0016] The shape of the discharge part (x1) is not particularly limited. The discharge part (x1) in FIG. 1 is one embodiment of a tapered shape in which a flow path for the contents is formed, sloping from the opening of the container body (x2) toward one discharge outlet (x1-1), and the discharge outlet (x1-1) is disposed at the tip of the tapered shape. Furthermore, when the discharge part (x1) has two or more discharge outlets (x1-1), for example, the discharge part (x1) may have a so-called comb-like shape in which multiple comb teeth extend from the opening of the container body (x2) toward each discharge outlet (x1-1) (not shown). In this case, the position of the discharge outlet (x1-1) on the comb teeth is not limited to the tip of the comb teeth, and any appropriate position can be selected, such as the center of the surface or the base of the comb teeth.

[0017] The inner diameter of the discharge port (x1-1) is 1.2 mm or more from the viewpoint of ensuring good dischargeability of the composition (A) while preventing unnecessary leakage from the discharge port (x1-1) when the container (X) is in an inverted or tilted position, and is preferably 1.5 mm or more and 5 mm or less, preferably 4 mm or less, and more preferably 3 mm or less from the viewpoint of ensuring good dischargeability of the content and preventing unnecessary leakage.

[0018] The internal volume of the container body (x2) is preferably 50 mL or more, may be 70 mL or more, or may be 90 mL or more, from the viewpoint of not interfering with the support (Y) in holding the container (X) in an inverted or tilted state, and from the viewpoint of ensuring that the desired amount of composition (A) is filled, and is preferably 220 mL or less, may be 200 mL or less, or may be 180 mL or less.

[0019] The outer diameter of the container body (x2) is preferably 35 mm or more, and may be 45 mm or more, from the viewpoint of stably holding the container (X) in an inverted or tilted state by the support (Y) and from the viewpoint of easily discharging the composition (A), and is preferably 60 mm or less, and may be 50 mm or less.

[0020] The form of the container (X) is not particularly limited, as long as it has a discharge portion (x1) and a container body (x2) as a container and is deformable by the application of an external force or the like. Examples of the form of the container (X) include a squeeze-type container having a container body (x2) that can be deformed by squeezing, a tube container having a cap portion as the discharge portion (x1), and a spout container having a pouch container body as the container body (x2). Among these, squeeze-type containers are preferred from the viewpoint of convenience, since the composition (A) can be easily discharged by pressing the body portion of the container body (x2).

[0021] The material of the container (X) is not particularly limited, and is preferably a flexible soft packaging material that can be deformed by applying an external force, etc. For example, it may be a multi-layered sheet material made of a synthetic resin layer such as polyethylene, polypropylene, or polyethylene terephthalate, or a metal layer such as aluminum. Furthermore, different materials may be selected depending on the parts of the container (X), such as the discharge part (x1), the container body (x2), and the bottom surface of the container body (x2).

[0022] When using the kit of the present invention, the container (X) is held on a support (Y) with the discharge portion (x1) facing downward and the bottom surface of the container body (x2) facing upward, so that the container (X) is in an inverted or tilted position.

[0023] As shown in the side view of Figure 2(a), the inverted state of the container (X) refers to the state of the container (X) when the angle θ between a vertical line 11 passing through the center of gravity O of the container body (x2) and a line 12 passing through the center of gravity O of the container body (x2) and the center P of the bottom surface of the container body (x2), i.e., the angle θ between the vertical line 11 and the line 12, is 0°. Therefore, when the container (X) is in the inverted state, the vertical line 11 and the line 12 overlap, the discharge portion (x1) and the discharge port (x1-1) face directly downward, and the bottom surface of the container body (x2) faces directly upward.

[0024] 2(b), the inverted state of the container (X) refers to the state of the container (X) when the angle θ between a vertical line 11 passing through the center of gravity of the container body (x2) and a line 12 passing through the center of gravity O of the container body (x2) and the center P of the bottom surface of the container body (x2), i.e., the angle θ between the vertical line 11 and the line 12, is greater than 0° and not greater than 80°. Therefore, in the inverted state of the container (X), the line 12 is tilted diagonally downward at an angle of θ° with respect to the vertical line 11, compared to the container (X) in the normally inverted state. The included angle θ of the container (X) in an inverted state is greater than 0°, preferably 5° or more, and is 80° or less, preferably 45° or less, and more preferably 10° or less, from the viewpoint of ensuring good dischargeability and preventing unnecessary leakage, while taking into consideration the balance with the viscosity of the composition (A).

[0025] The support (Y) provided in the kit of the present invention is a member for holding a container (X) with the discharge portion (x1) facing downward and the bottom surface of the container body (x2) facing upward, i.e., the container (X) in an inverted or tilted position, and has a mechanism for holding the container (X) in an inverted or tilted position. Two examples of specific shapes that the support (Y) can take are shown in Figures 3(a) and 3(b). Note that both Figures 3(a) and 3(b) show a support (Y) (stand (y1)) in a stand-type shape.

[0026] 3(a) and 3(b) has a fitting portion 21 for fitting to the discharge portion (x1) as a mechanism for holding the container (X) in an inverted or tilted position to enhance adhesion with the downward-facing discharge portion (x1) and stably hold the container (X). This allows the container (X) to be stably held in an inverted or tilted position from the start to the end of the treatment in which discharge and application are repeated, and also contributes to effectively preventing unnecessary leakage of the composition (A) from the discharge port (x1-1).

[0027] In the stand (y1) of Fig. 3(a), the outer wall of the fitting portion 21 has a tapered shape that slopes downward in accordance with the shape of the discharge portion (x1) and the inner wall of the fitting portion 21. On the other hand, in Fig. 3(b), the outer wall of the stand (y1) has a cylindrical shape overall, with a concave fitting portion 21 on the upper surface, and the inside of the stand (y1) has a hollow between the outer side wall and the fitting portion 21. In particular, from the viewpoint of reducing the overall weight of the kit of the present invention and increasing its cost advantage, it is preferable that the support body (Y) be a stand (y1) as shown in Fig. 3(b).

[0028] The material of the support (Y) is not particularly limited as long as it can withstand the load of the container (X) in the upside-down or inverted position and the repeated operations of dispensing and applying, and may be made of paper such as cardboard, or resin such as synthetic resin, etc. Among these, paper is preferred from the viewpoints of reducing weight and increasing cost advantages.

[0029] When the kit of the present invention is used, when the support (Y) is placed on a horizontal plane and the container (X) is held on the support (Y) in an inverted or upside-down position, the intersection of the vertical line 12 passing through the center of gravity O of the container body (x2) and the horizontal plane on which the support (Y) is placed is located within the horizontal plane enclosed by the lowest end of the support (Y).

[0030] Specifically, for example, when the support (Y) is the stand (y1) shown in FIG. 3(b), a longitudinal cross-sectional view of a container (X) is shown in FIG. 4, in which the container (X) is held in an inverted position. As shown in FIG. 4, when using the kit of the present invention, the discharge portion (x1) of the container (X) is inserted from above into the fitting portion 21 of the stand (y1) to hold the container (X). The stand (y1) is disposed on a horizontal plane 31, and the horizontal plane 31 enclosed by the lowest end portion y1-1 of the stand (y1) corresponds to the horizontal plane yz. In the kit of the present invention, the intersection 32 of the vertical line 12 passing through the center of gravity O of the container body (x2) and the horizontal plane 31 on which the stand (y1) is disposed is located within the horizontal plane yz enclosed by the lowest end portion (y1-1) of the stand (y1). Furthermore, when the support (Y) is the stand (y1) shown in Figure 3(a), the stand (y1) itself has a bottom surface, so the horizontal plane yz corresponds to the bottom surface of the stand (y1). Furthermore, even when the container (X) is held in an inverted upright position, the intersection 32 with the horizontal plane 31 on which the stand (y1) is placed will inevitably be located within the horizontal plane yz surrounded by the lowest end (y1-1) of the stand (y1).

[0031] The kit of the present invention that satisfies these conditions can fill the container (X) with composition (A) having a specific viscosity and stably maintain the composition (A) from the start to the end of the treatment in which the discharge and application are repeated, i.e., until the fully filled composition (A) is used up. In this specification, the term "fully filled composition" refers to the composition filled in the container (X) immediately after the container (X) is filled with the composition (A) when using the kit of the present invention. Usually, the container (X) is filled with the composition (A) at a filling rate appropriately selected from the range of 50 to 77%.

[0032] Another example of a specific form that the support (Y) included in the kit of the present invention can take is shown in Figure 5. In Figure 5, the housing (y2) has a mechanism for holding the container (X) in an inverted or tilted position, and a part of the housing (y2) holds the container (X) in an inverted or tilted position. That is, in this embodiment, the support (Y) is integrated with the housing (y2) having a mechanism for holding the container (X) in an inverted or tilted position, and a part of the housing (y2) forms a form that holds the container (X) in an inverted or tilted position during use.

[0033] Therefore, the support (Y) is preferably a housing (y2) from the viewpoint of also functioning as a packaging material. If the kit of the present invention is configured in such a manner that the composition (A) and the container (X) are packaged in the housing (y2), it is possible to reduce the weight and simplify the entire kit, and the cost advantage can be further enhanced. In addition, since the container (X) in the upside-down or inverted position is supported by the entire housing (y2), it is also possible to easily further stabilize the holding ability of the container (X).

[0034] From the viewpoint of stabilizing the holding ability of the container (X) while ensuring the function of the housing (y2) as a packaging material for the composition (A) and the container (X), it is preferable that the housing (y2) has outer dimensions of a short side of 50 mm or more and 150 mm or less, a long side of 100 mm or more and 200 mm or less, and a height of 30 mm or more and 120 mm or less.

[0035] FIG. 6 is a side view of FIG. 5 showing a state in which the container (X) is held in an inverted position when a portion of the housing (y2) is configured to hold the container (X) in an inverted or tilted position during use. As shown in FIG. 6, when using the kit of the present invention, the discharge port (x1) of the container (X) is inserted from above into a hole 34 formed in the upper surface of the housing (y2) to hold the container. The housing (y2) is disposed on a horizontal plane 31, and the bottom surface of the housing (y2) corresponds to the horizontal plane yz. In the kit of the present invention, even in this case, the intersection 32 of the vertical line 12 passing through the center of gravity O of the container body (x2) and the horizontal plane 31 on which the housing (y2) is disposed is located on the horizontal plane yz, which is the bottom surface of the housing (y2).

[0036] Furthermore, two specific examples of a form in which a part of the housing (y2) holds the container (X) in a normal or obliquely inverted state are shown in Figs. 7(a) and 7(b). In FIG. 7( a), a perforated cut 41 is provided on the top surface of the housing (y2), and a mechanism is provided for forming a hole 34 into which the container (X) can be inserted from above. Therefore, during use, a portion of the top surface of the housing (y2) is cut away along the cut 41, and then the container (X) is inserted into the formed hole 34. Also, a cut 41 is provided on the top surface of FIG. 7( b), and during use, the housing (y2) is folded upward along the cut 41 to secure an area 411, which serves as a support wall for supporting the container (X). The housing (y2) is further folded downward along the cut 41 to secure an area 412, into which the container (X) can be inserted from above. The manner in which a portion of the housing (y2) is used to hold the container (X) in a normal or obliquely standing position is not limited to these examples, and may be appropriately designed taking into consideration the ability to hold the container (X) in a normal or obliquely standing position.

[0037] More specifically, for example, the maximum diameter of the hole 34 is preferably 2 mm or more larger than the outer diameter of the container (X), more preferably 3 mm or more larger, and even more preferably 4 mm or more larger, in order to make it easier to repeatedly insert the container (X) from above. Furthermore, from the viewpoint of stably holding the container (X), the maximum diameter of the hole 34 is preferably 12 mm or less, more preferably 10 mm or less, and even more preferably 8 mm or less. Therefore, from the viewpoint of comprehensively taking into consideration the ease of repeated insertion of the container (X) from above and the stable holding of the container (X), it is particularly preferable that the maximum diameter of the hole 34 be 4 mm or more and 8 mm or less.

[0038] Furthermore, the difference between the maximum diameter of the hole 34 and the outer diameter of the container body (x2) is preferably 2 mm or more, and may be 4 mm or more, and is preferably 12 mm or less, and may be 8 mm or less, from the viewpoint of stably holding the container (X) in an inverted or tilted position while making it easy to repeatedly insert the container (X) from above.

[0039] As shown in FIG. 6, when the support (Y) is placed on a horizontal plane 31 and the container (X) is in an inverted or tilted position, the ratio (Y a / X a ) may vary depending on the form of the support (Y), but from the viewpoint of stably holding the container (X) from the start to the end of the treatment in which dispensing and application are repeated, it is preferably 0.1 or more, more preferably 0.5 or more, even more preferably 1 or more, and preferably 20 or less, more preferably 15 or less, even more preferably 10 or less. More specifically, for example, when the support (Y) is a stand (y1), the ratio (Y) of the area of ​​the horizontal plane yz enclosed by the lowest end (y1-1) of the support (Y) to the area of ​​the horizontal cross section xz of the container body (x2) passing through the center of gravity O of the container body (x2) is a / X a ) is preferably 0.1 or more and preferably 1.5 or less. When the support (Y) is a housing (y2), the ratio (Y) of the area of ​​the horizontal plane yz enclosed by the lowest end (y1-1) of the support (Y) to the area of ​​the horizontal cross section xz of the container body (x2) passing through the center of gravity O of the container body (x2) is a / Xa ) is preferably 1 or more and preferably 15 or less.

[0040] Composition (A) included in the kit of the present invention is a composition filled into the container (X) at the time of use, and has a viscosity of 600 mPa·s or more and 50,000 mPa·s or less at 30° C. When composition (A) has the above viscosity, coupled with the fact that the outlet of the discharge part of container (X) has a specific inner diameter, it is possible to easily extrude the contents from the outlet (low pressing pressure) and effectively prevent unwanted leakage from the outlet.

[0041] From the viewpoint of preventing unnecessary leakage from the discharge port, the viscosity of composition (A) at 30°C is 600 mPa·s or more, preferably 1000 mPa·s or more, more preferably 3000 mPa·s or more, even more preferably 5000 mPa·s or more, and is 50000 mPa·s or less, preferably 40000 mPa·s or less, more preferably 35000 mPa·s or less, even more preferably 30000 mPa·s or less.

[0042] The viscosity of composition (A) at 30° C. means a value measured by a Brookfield viscometer, and specifically, is measured by the method described in the examples.

[0043] From the viewpoint of effectively imparting the above viscosity, the composition (A) preferably contains an ionic surfactant (a1) and a higher alcohol (a2). Specific examples of the ionic surfactant of component (a1) include one or two selected from anionic surfactants (a1-1) and cationic surfactants (a1-2).

[0044] Examples of the anionic surfactant of component (a1-1) include anionic surfactants having a sulfate group, specifically one or more selected from alkyl sulfates, alkenyl sulfates, polyoxyalkylene alkyl ether sulfates, polyoxyalkylene alkenyl ether sulfates, and polyoxyalkylene alkyl phenyl ether sulfates.

[0045] Examples of the cationic surfactant of component (a1-2) include one or more selected from secondary to quaternary ammonium salts. Specific examples include cetyltrimethylammonium chloride (cetrimonium chloride), stearyltrimethylammonium chloride (steartrimonium chloride), isostearyltrimethylammonium chloride (isostearyltrimonium chloride), lauryltrimethylammonium chloride (lauryltrimonium chloride), behenyltrimethylammonium chloride (behentrimonium chloride), cocoyltrimethylammonium chloride (cocotrimonium chloride), and cetyltrimethylammonium bromide (cetrimonium bromide). , stearyltrimethylammonium bromide (steartrimonium bromide), lauryltrimethylammonium bromide (lauryltrimonium bromide), isostearyl lauryl dimethylammonium chloride (isostearyl lauryl dimonium chloride), dicetyl dimethylammonium chloride (dicetyldimonium chloride), distearyl dimethylammonium chloride (distearyldimonium chloride), and dicocoyl dimethylammonium chloride (dicoccodimonium chloride).

[0046] Specific examples of the higher alcohol of component (a2) include higher alcohols having a linear or branched hydrocarbon group with a carbon number of 6 to 36. Examples of such component (a2) include one or more selected from myristyl alcohol, cetanol, stearyl alcohol, arachyl alcohol, behenyl alcohol, and oleyl alcohol.

[0047] From the viewpoint of effectively imparting the above-mentioned viscosity, the mass ratio (a2 / a1) of the content of component (a2) to the content of component (a1) (the total content of components (a1-1) and (a1-2)) in composition (A) is preferably 0.1 or more, more preferably 0.5 or more, even more preferably 1 or more, still more preferably 2.5 or more, more preferably 8 or less, even more preferably 6 or less, and still more preferably 4 or less. The mass ratio (a2 / a1) of the content of component (a2) to the content of component (a1) in composition (A) is preferably 0.1 or more, more preferably 0.5 to 8, even more preferably 1 to 6, and even more preferably 2.5 to 4.

The container (X) was then quickly placed on the support (Y) at a narrow angle θ for 3 minutes, and the container (X) was then picked up and immediately (within 10 seconds) the body of the container body (x2) was pressed with the discharge outlet facing downwards to discharge and evaluate the composition (A). 4: The pressure caused the squeeze container to dent, allowing the liquid to be smoothly discharged from the outlet. 3: The pressure caused the squeeze container to dent, and the liquid was discharged from the outlet somewhat smoothly. 2: The squeeze container was dented by pressure, and the contents were not discharged smoothly from the outlet. 1: No discharge occurred due to the dent in the squeeze container caused by pressure.

[0088] Drip Evaluation When the container (X) was turned upside down, the extent to which the composition (A) dripped from the discharge port and the extent to which the composition (A) dripped from the hair after application were visually confirmed and evaluated according to the following criteria. Specifically, the first and second components were mixed at room temperature (about 25°C) for 30 seconds, and composition (A) was quickly filled into container (X) at room temperature. After that, container (X) was left standing upside down (θ=0°) for 1 minute, and the amount (g) of composition (A) that dripped from the discharge port was measured. 4: No dripping at all 3: The amount that dripped was less than 0.5g 2: The amount that dripped was 0.5g or more but less than 1g 1: The amount that dripped was 1g or more

[0089] <Evaluation of Ease of Dispensing Depending on the Degree of Pressure> The ease of pressing the container (X) when discharging the composition (A) from the container (X) at room temperature (about 25° C.) was evaluated by a specialist panel according to the following criteria. 4: It was possible to easily discharge with low pressure. 3: Discharge was fairly easy with a relatively low pressure 2: A little bit of pressure was required and it was a little difficult to dispense 1: High pressure was required and it was difficult to dispense

[0090] <<Evaluation of the support>> The container (X) was placed on the support (Y) in an upside-down or obliquely upside-down position, and the holding stability of the container (X) was evaluated according to the following criteria. ◯: The container was able to be held without falling over. ×: The container fell over.
