FIG. 2 is a side view of the foldable container according to the first embodiment. FIG. 3 is a front view of the foldable container according to the first embodiment. FIG. 4 is a plan view of the foldable container according to the first embodiment. FIG. 5 is an exploded view before forming the foldable container according to the first embodiment.

The collapsible container 100 according to the first embodiment is formed by folding a single sheet-like member shown in FIG. It has an expanding box shape. The collapsible container 100 has a bottom surface 20A, a pair of first sides 20L, 20R and a pair of second sides 20F, 20B. The bottom surface 20A has a square shape. Although a square is shown as an example in this embodiment, a rectangle may be used. The bottom surface 20A has two mountain-fold folds L1 and L2 that connect diagonally, and a valley-fold fold L3 that connects the midpoints of the bases 22L and 22R of the first side surfaces 20L and 20R that are continuous with the bottom surface 20A. ing. In the present embodiment, the crease in which the top portion faces the inside of the foldable container 100 is defined as a mountain fold, and the fold in which the top portion faces the outside of the foldable container 100 is defined as a valley fold.

The first side surfaces 20L and 20R are each folded back from the bottom surface 20A so as to form an obtuse angle of inclination θ1 (see FIG. 2) and face each other via the bottom surface 20A. The first side surfaces 20L and 20R each have a trapezoidal shape and have mountain fold lines L3L and L3R. The first side surfaces 20L, 20R have bases 22L, 22R connected to the bottom surface 20A, and open sides 21L, 21R opposite to the bases 22L, 22R. The creases L3L and L3R are connected to the crease L3 on the bottom surface 20A and connect the midpoints of the bottom sides 22L and 22R and the open sides 21L and 21R. Tabs TL and TR generated when forming the first side surfaces 20L and 20R, that is, when forming the collapsible container 100, are folded on the inner surfaces of the first side surfaces 20L and 20R. In this embodiment, the tabs TL and TR are thermally welded to the first side surfaces 20L and 20R to form a thermally welded portion HS. It should be noted that an adhesive or adhesive may be used instead of heat welding. By providing creases L3L, L3R only on the first side surfaces 20L, 20R, creases can be reduced and hair dye pooling on the creases can be reduced.

The second side surfaces 20F and 20B are each folded back from the bottom surface 20A so as to form an inclination angle θ1 (see FIG. 3) and face each other via the bottom surface 20A. The second side surfaces 20F, 20B each have a trapezoidal shape and do not have folds. The second side surfaces 20F, 20B have bases 22F, 22B connected to the bottom surface 20A, and open sides 21F, 21B opposite to the bases 22F, 22B.

As shown in FIGS. 2 and 3, each base 22L, 22F of the first side 20L and the second side 20F has a length LL (cm), and each open side 21L, 21F has a length UL (cm). The collapsible container 100 has a height H (cm). An inclination angle θ1 formed by the bottom surface 20A, the first side surface 20L, and the second side surface 20F is defined by the following formula.
θ1=180−(tan ⁻¹ (2H/(UL−LL))×180/π)
The same applies to the first side surface 20R and the second side surface 20B, and the first side surface 20L and the second side surface 20F will be described below as an example.

As will be described later, the collapsible container 100 for foaming the hair dye preferably has an inclination angle θ1 of 100° to 120°. Also, the length LL of each of the bottom sides 22L and 22F is preferably 9.0 to 15.0 cm, and the length UL of each of the open sides 21L and 21F is preferably 16.0 to 22.0 cm. Also, the ratio of each base 22L, 22F, that is, each open side 21L, 21F, that is, one side of the open side to one side of the base (base/open side) is preferably 0.52 to 0.76. Furthermore, it is desirable that the height of the foldable container 100 is 5.0 to 10.0 cm. In addition, it is desirable to have a volume of 1000 cm ³ or more in order to generate the amount of foamed hair dye required for dyeing the entire hair.

As shown in FIG. 5, the foldable container 100 is formed by folding a single pre-processed resin sheet material 100b along fold lines L1, L2, L3, L3L, L3R, L4, L5, L6, and L7. . The pre-processed sheet material 100b is made of polypropylene, for example, and preferably has a thickness of 0.1 mm to 0.3 mm, more preferably 0.18 mm. Since the collapsible container 100 is formed by folding one sheet material, it is possible to prevent leakage of the hair dye from the seams and joints of the surfaces that may occur when combining a plurality of surface members. It should be noted that folds are denoted by the same reference numerals as long as they are common to mountain folds or valley folds. After being folded, the sheet material 100b before processing includes a bottom surface forming portion 20Ab, a first side forming portion 20Lb, which constitute a bottom surface 20A, first side surfaces 20L and 20R, second side surfaces 20F and 20B, tabs TL and TR, 20Rb, second side forming portions 20Fb and 20Bb, and tab forming portions TLb and TRb. The pre-processed sheet material 100b is desirably made of a transparent or translucent resin so that the contents can be visually recognized.

FIG. 6 is an explanatory diagram showing a state when the foldable container according to the first embodiment is folded. In FIG. 6, the structures that can be confirmed through transmission are shown in parentheses. When the foldable container 100 is folded, the first side surfaces 20L and 20R are folded along the fold lines L3L and L3R, respectively, and stored inside the second side surfaces 20F and 20B. Therefore, the folded foldable container 100 has a substantially plate-like shape with the second side surfaces 20F and 20B as the front and back surfaces. The folded collapsible container 100 has a length L (cm) and a width W (cm). The maximum length of the folded collapsible container 100 is between 16.0 cm and 22.0 cm, and the maximum width is between 5.0 cm and 10.0 cm.

Regarding the collapsible container 100, from the aspect of foaming the hair dye and the aspect of being used in a hair dye set that is sold together with the hair dye and foaming member in a product box, the following It is desirable that the conditions are satisfied.
・There are widely used existing dimensions for the product box, and the dimensions of the store display shelf are the dimensions of the existing product box, e.g. It is determined according to 10 cm. Therefore, product boxes that are larger than the existing size may not fit on the shelf and cannot be displayed and sold. Also, the larger dimensions are more costly to transport and store. Therefore, collapsible containers are required to have dimensions that can be accommodated in product boxes of existing dimensions.
- The collapsible container 100 is required to have resilience to immediately restore its desired shape even after being stored for a long period of time until use. If the restorability is poor, for example, if the degree of restoration is low, the hair dye cannot be foamed well, and if it takes a long time to restore, the ease of use for the user is hindered.
・Foldable containers with few creases and corners are required. In a collapsible container with a complicated structure with many corners and folds, the amount of mixed liquid that accumulates in the corners and creases increases, and there is a possibility that the entire amount of hair dye put into the collapsible container cannot be foamed efficiently.
・The target of foaming is a hair dye or bleaching agent, and it is required that the foam does not scatter around the collapsible container. The surrounding area may be dyed by the dye contained in the hair dye, or may be bleached by the bleaching agent, or may cause color unevenness due to the reduction in the amount of the agent used for foaming.
・Usually, hair dyes contain alkaline agents, oxidizing agents, and oxidation dyes, and gloves are used to avoid contact with the skin. Therefore, there is a need for a collapsible container that can be foamed without the foam sticking to, for example, the arm, which is not protected by gloves.
- For example, when a foaming member such as a foaming net is kneaded by hand to foam a hair dye, a shape that allows easy insertion of the hand and movement of the hand within the foldable container is required. In addition, it is required that the hair dye does not easily spill out when the hair dye is foamed by hand kneading.

Considering the above points, the dimensional characteristics suitable for the collapsible container 100 for foaming the hair dye were verified. For the verification, a hair dye having the following composition was used.

The foaming procedure, ie lathering, was carried out according to the following procedure.
(1) The collapsible container in a folded state is unfolded to form the collapsible container 100, and a foaming net is put thereinto, and the first agent and the second agent are introduced so as to cover the foaming net.
(2) Put on rubber gloves and rub the inside of the collapsible container 100 as if gripping a foaming net to create foam. At this time, it is desirable to foam by repeating "rubbing the foaming net" and "stirring the bottom surface several times so as to draw a circle so that the liquid permeates the foaming net".
(3) Continue whipping until the collapsible container 100 is filled with foam or until the entire mixture becomes foam.
(4) The resulting foamy mixed solution was directly placed on the hand wearing a rubber glove, and the entire hair of a hair test doll (manufactured by Beaulux Co., Ltd. "Cut Mannequin No. 775S") was applied by hand. Apply it, raise your fingers and gently rub it all over your hair and lather it up on your head. If the collapsible container 100 is filled before the entire amount of the mixed liquid becomes foamy, the remaining mixed liquid is used to foam again, and the foamed mixed liquid is applied.
(5) After leaving for 20 minutes, wash off, apply shampoo and conditioner, and dry.

Evaluation of the container was performed by the following evaluation methods.
10 panelists performed foaming and hair dyeing operations under the condition of 25°C and evaluated them.
(A) Evaluation criteria for “easy to lather” were evaluated with two choices: “Easy to move hands and easy to lather” and “Hard to move hands and difficult to lather”. ,
10 to 8 people were rated as excellent (1), 7 to 5 people were rated as acceptable (2), and 4 or less people were rated as unsatisfactory (3).
(B) Evaluation criteria for "container stability" Evaluation is performed by two options: "Container is stable and foam does not spill from the container" and "Container is unstable and foam spills". The number of panelists who answered that the foam does not spill from the container due to
10 to 8 people were rated as excellent (1), 7 to 5 people were rated as acceptable (2), and 4 or less people were rated as unsatisfactory (3).
(C) Evaluation criteria for ``usability'' ``Hair dyeing was possible without staining the arm parts and surroundings not protected by gloves'', ``The arm parts not protected by gloves and the surroundings were stained by bubbles The number of panelists who answered "I was able to dye my hair without staining the arm parts and surroundings that are not protected by gloves" was
10 to 8 people were rated as excellent (1), 7 to 5 people were rated as acceptable (2), and 4 or less people were rated as unsatisfactory (3).
On top of that, as a comprehensive evaluation result of the three evaluation criteria, up to two were judged to be acceptable (2).

Table 3 shows the verification results of Examples 1 to 3 when the open side length UL and height H are constant and the base side length LL is changed. The open side length UL was set to 17.2 cm from the viewpoint of storage in the product box and usability. Strictly speaking, the length is not required to be 17.2 cm. The collapsible container 100 has first side surfaces 20L, 20R and second side surfaces 20F, 20B formed on the bottom surface to improve foamability (A), container stability (B), and usability (C). 20A is folded back at an inclination angle .theta.1. That is, the first side surfaces 20L, 20R and the second side surfaces 20F, 20B are provided with an inclined angle so that the opening area widens from the bottom surface 20A toward the opening, thereby facilitating putting the palm in and out of the container. , the interference between the open sides 21F, 21B, 21L, 21R and the wrist is prevented or reduced during the foaming operation in the container.

In Table 4, when the open side length UL and the base length LL are constant and the height H is changed, when the base side length LL and the height H are constant and the open side length UL is changed, the height is constant. , the open side length UL and the bottom side length LL are shown as Examples 4 to 10. The height H was set to 8 cm from the viewpoint of storage in the product box and usability. Note that the length is not strictly required to be 8 cm, and may be approximately 8 cm, for example, 5 cm to 10 cm.

According to the verification results in Tables 3 and 4, if the inclination angle θ1 is 100° to 120°, there is no failure (3) in the evaluation of the ease of foaming (A), and the inclination angle θ1 is 100° If it is up to 114°, it is only excellent (1) in both evaluation of ease of foaming (A) and stability of container (B). If the angle of inclination θ1 is less than 100°, the evaluation of ease of foaming (A) is not possible (3), and from the viewpoint of ease of foaming (A), it is desirable that the angle of inclination θ1 is 100° or more. That is, as the inclination angle θ1 approaches a right angle, it becomes difficult to put the palm in and out of the container. Further, when the height H is increased, the open side hits the wrist or the like during foaming operation such as hand kneading of the foaming member in the container, resulting in difficulty in foaming (Comparative Examples 5 and 8). Therefore, it is desirable that the height H is less than 13 cm, more preferably 10 cm or less. Furthermore, when the base length LL is short, that is, when the contact area of the container is small, the movement of the palm during the foaming operation inside the container is restricted (Comparative Example 1). Therefore, the base length LL is preferably 7 cm or more, and more preferably 10 cm or more.

In general, the longer the open side length UL, the larger the open area, making it easier for not only the palm but also the wrist and the arm to enter the container, making it easier for the container to come into contact with the foamed hair dye, resulting in reduced usability. . Further, when the volume of the container is less than 1000 cm ³ , the foamed hair dye tends to overflow from the container and adhere to the wrists and arms, resulting in reduced usability (Comparative Example 4). Due to the dimensional restrictions of the product box, the lengths that can be taken as the open side length UL and the bottom side length LL are limited, so if the height H is reduced, the required volume cannot be secured. According to the verification results in Tables 3 and 4, from the viewpoint of usability (C), the open side length UL is preferably 22 cm or less, more preferably 20 cm or less, and the height H is preferably 5 cm or more.

In general, when the base length LL is short, that is, when the contact area of the container is small, the stability of the container is lowered (Comparative Example 1). Also, if the base length LL is short or the height H is low, the volume required for the container cannot be ensured (Comparative Examples 1 and 4). As a result, the stability (B) of the container is reduced. According to the verification results in Tables 3 and 4, from the viewpoint of container stability (B), the length of the base LL is 7 cm or more, preferably 10 cm or more, and the height H is preferably 5 cm or more.

To summarize the above verification results, it is desirable that the foldable container 100 has an inclination angle θ1 of 100° to 120° and a volume of 1000 cm ³ or more. In addition, the ratio of the length of the base length LL to the length of the open side length UL (base/open side) is 0.52 to 0.76, the base length LL is 9.0 cm to 15.0 cm, and the open side length LL is 9.0 cm to 15.0 cm. More preferably, the side length UL is 16.0 cm to 22.0 cm and the height H is 5.0 cm to 10.0 cm. Further, it is desirable that the bottom side length LL is 13.0 cm, the open side length UL is 17.2 cm, and the height H is 5.0 cm to 10.0 cm. In this case, the collapsible container 100 that secures the required volume, is compact when folded, and is excellent in ease of whipping (A), container stability (B), and usability (C) is realized. can do.
