Description

The present disclosure relates to an applicator that is used by being attached to a discharge container.

There is an applicator that is used by being attached to a dispensing container. For example, Patent Document 1 describes an applicator having a plurality of comb teeth with a flow path formed therein as an applicator used by being attached to a discharge container filled with a hair coloring agent. When dyeing hair, a user uses such an applicator to comb the hair with a plurality of comb teeth while discharging a hair coloring agent from an outlet formed in each comb tooth. This causes the hair coloring agent to be applied to the hair.

Patent No. 5060908

If a certain period of time has passed since the hair dyeing process, the difference in color between the dyed part of the hair and the root part that has grown after the hair dyeing process will become noticeable, so only the roots that have grown after the hair dyeing process will be dyed. There may arise a desire to dye, so-called retouching. In this case, it is required to apply the hair coloring agent only to the roots of the hair. However, with the applicator described in Patent Document 1, it was difficult to apply the hair coloring agent only to the root portion of the hair. Moreover, such a problem may occur not only in hair coating agents such as hair coloring agents, but also in scalp coating agents such as hair growth agents and scalp moisturizers.

One aspect of the present disclosure provides a technique for making it easier to selectively apply a liniment to the root portion of hair using an applicator that is attached to a discharge container and has a plurality of comb teeth.

One aspect of the present disclosure is an applicator that is used by being attached to a discharge container.

Hereinafter, exemplary embodiments of the present disclosure will be described with reference to the drawings.
[1. composition]
A dispensing container 1 with an applicator shown in FIG. 1 includes a dispensing container 2 and an applicator 3 that can be attached to and detached from the dispensing container 2.

The discharge container 2 is a container that stores a coating agent therein and discharges the stored coating agent to the outside. Specifically, the discharge container 2 accommodates a two-part hair coloring agent, which is an example of a hair coating agent. The discharge container 2 includes a first accommodating part 21, a second accommodating part 22, a connecting part (not shown), and an exterior part 23. In the following explanation, preparations that function as a liniment when mixed with other preparations, such as the first and second parts of a two-part hair coloring agent, are also referred to as liniments. .

The first accommodating part 21 and the second accommodating part 22 are well-known aerosol containers that accommodate a coating agent therein. The first accommodating portion 21 and the second accommodating portion 22 have a cylindrical shape with a bottom (in this embodiment, a cylindrical shape with a bottom). The first accommodating portion 21 accommodates a first agent of hair coloring agent. The second accommodating portion 22 accommodates a second hair coloring agent. A stem (not shown) is provided at the upper part (that is, one end in the axial direction) of the first accommodating part 21 and the second accommodating part 22, respectively. The coating agent accommodated in the first accommodating part 21 and the second accommodating part 22 is discharged from each stem to the outside by pushing down each stem.

The connecting portion (not shown) is a member that connects the upper portions (that is, the ends where the stem is located) of the first accommodating portion 21 and the second accommodating portion 22 when they are arranged side by side. A merging channel is formed in the connecting portion to merge the coating agents discharged from the first accommodating portion 21 and the second accommodating portion 22 into one. The merging flow path is connected to an internal flow path 53 of a comb portion 50 of the applicator 3, which will be described later.

The exterior part 23 is a member that covers the outer periphery of the first accommodating part 21 and the second accommodating part 22, which are arranged side by side, so as to bundle them together. The exterior portion 23 is made of, for example, a resin film.

The applicator 3 is a mounting tool that is attached to the discharge container 2. The applicator 3 is used to apply the liniment contained in the discharge container 2 to the hair. The applicator 3 includes a mounting section 40, a comb section 50, and an operation section 60. The mounting part 40, the comb part 50, and the operating part 60 are made of resin, for example.

The mounting part 40 is configured to be able to be mounted on the discharge container 2 so as to cover at least the connection part in the discharge container 2. The mounting portion 40 has a cylindrical shape (in this embodiment, a cylindrical shape with an oval outer shape). For example, the mounting portion 40 has an inner diameter that is approximately the same as the outer diameter of the connecting portion in the discharge container 2, and is configured such that the connecting portion can be fitted inside.

The comb portion 50 is configured to be detachable from one end of the mounting portion 40 in the axial direction. The comb portion 50 includes a base portion 51 and a plurality of comb teeth 52 erected on the base portion 51. The comb portion 50 of this embodiment includes five comb teeth 52.

The base portion 51 is a wall-shaped portion that closes one cylindrical opening of the mounting portion 40 . The surface of the base 51 of this embodiment, that is, the upright surface 511 on which the plurality of comb teeth 52 are erected, is planar.

As shown in FIGS. 1 to 3, each of the plurality of comb teeth 52 is a portion extending from the upright surface 511 and having a rod-like outer shape. Hereinafter, the end of each comb tooth 52 on the side of the standing surface 511 in the extending direction will be referred to as a base end 521, and the end on the opposite side will be referred to as a tip end 522. The thickness of the plurality of comb teeth 52 in this embodiment is constant except for the tip portion 522. The tip portion 522 of each comb tooth 52 is formed into a tapered shape. The tip angle of the tip portion 522 is an acute angle. Moreover, each of the plurality of comb teeth 52 has a shape that extends while being curved. The central axis A (see FIG. 3) of each comb tooth 52 in the extending direction is curved. In the plurality of comb teeth 52 of this embodiment, the degree of curvature of the central axis A is gentler as the comb teeth 52 are more central. The plurality of comb teeth 52 are configured such that all of their tip portions 522 are not located on the same plane.

Each of the plurality of comb teeth 52 has a dimension M along the next reference straight line B of 25 mm or more. The reference straight line B is a straight line that passes through an end point P1 on the central axis A of the comb teeth 52 on the proximal end 521 side and an end point P2 on the distal end 522 side. An end point P1 on the base end portion 521 side is an intersection between the central axis A of the comb teeth 52 and the upright surface 511. An end point P2 on the tip portion 522 side is the intersection of the central axis A of the comb teeth 52 and the end surface of the comb teeth 52 on the tip portion 522 side. From the viewpoint of ease of applying the liniment to the root portion of the hair, the dimension M of each comb tooth 52 along the reference straight line B is preferably 30 mm or more.

The plurality of comb teeth 52 are arranged so as to be lined up on a linear parallel direction line C (see FIG. 1). The fact that the plurality of comb teeth 52 are lined up on the parallel direction line C means that the central axis A at the base end portion 521 of the plurality of comb teeth 52 intersects with the parallel direction line C, respectively.

As shown in FIG. 4, the plurality of comb teeth 52 have distal end portions 522 arranged in a row when viewed from the distal end portion 522 side (specifically, when viewed from a position facing the distal end portion 522 of the central comb tooth 52). It is arch-shaped. In other words, the tip tangent D, which is a line passing through the end point P2 on the tip 522 side of each comb tooth 52 in the order in which the comb teeth 52 are arranged, has an arch shape when viewed from the tip 522 side. In other words, the shortest distance S between the next reference straight line E and the end point P2 on the tip 522 side of each comb tooth 52 when viewed from the tip 522 side is farther away from the center comb tooth 52. The reference straight line E is a straight line that passes through the end points P2 of the two outer comb teeth 52 on the tip portion 522 side.

As shown in FIG. 2, the plurality of comb teeth 52 are arranged so that each extending direction spreads radially. Therefore, in this embodiment, the interval between adjacent comb teeth 52 is wider toward the tip end 522 side. The interval between adjacent comb teeth 52 is wide enough to prevent each comb tooth 52 from getting caught on the hair during the application operation to the hair, and the lubricant discharged from the discharge port 55 described later is caught between the comb teeth 52 on the hair. The design is narrow enough to reach all areas.

Further, the height H of the plurality of comb teeth 52 is higher toward the center. The height H of the comb teeth 52 referred to here is the height H of the comb teeth 52 with respect to the next reference plane F (that is, when the reference plane F is set to a height of 0). The reference plane F is a plane that passes through the lowest end point P1 in the thickness direction of the base 51 among the end points P1 of the plurality of comb teeth 52 on the base end 521 side, and is perpendicular to the thickness direction of the base 51. It is flat. In this embodiment, since the reference plane F includes the erected surface 511, the height H of the comb teeth 52 described above can also be referred to as the height H of the comb teeth 52 with respect to the erected surface 511.

An internal flow path 53 is formed in the comb portion 50 . The internal flow path 53 continues from an inlet 54 formed in the base 51 to an outlet 55 formed in each of the plurality of comb teeth 52 . The inflow port 54 and the discharge port 55 are communication holes that communicate the internal flow path 53 with the outside. The inflow port 54 is formed on the back surface of the base 51, that is, on the surface opposite to the upright surface 511. The discharge port 55 is formed at the tip 522 of each comb tooth 52. Specifically, one discharge port 55 is formed on each side of the distal end portion 522 of each of the plurality of comb teeth 52, that is, two discharge ports 55 in total are formed. The side surface of each comb tooth 52 refers to an outer surface of each comb tooth 52 around the central axis A that extends in a direction intersecting the direction in which the plurality of comb teeth 52 are arranged (that is, a direction intersecting the parallel direction line C). In other words, in the case of a comb tooth 52 that is sandwiched between other comb teeth 52 on both sides, the side surface of the comb tooth 52 refers to the outer surface of the comb tooth 52 that faces the other comb teeth 52 on both sides. Point. In addition, in the case of the outermost comb teeth 52, that is, the comb teeth 52 that are adjacent to other comb teeth 52 only on one side, the side surface of the comb teeth 52 refers to the outer surface of the comb teeth 52 that faces the other comb teeth 52. Refers to the outer surface and the opposite outer surface.

When the applicator 3 is attached to the discharge container 2, the internal channel 53 is connected to the above-mentioned merging channel at the inlet 54. Therefore, the coating agent discharged from the discharge container 2 flows into the internal flow path 53 from the inlet 54 via the converging flow path. Then, the coating agent passes through the internal flow path 53 and is discharged from the discharge port 55 .

Here, the comb portion 50 is divided into two members, a first member 50a and a second member 50b shown in FIGS. 5 and 6, approximately along a virtual curved surface defined by the central axis A of each of the plurality of comb teeth 52. configured to be possible. As shown in FIG. 6, a groove portion 56 is formed on the inner surface of the first member 50a. The second member 50b covers the opening of the groove 56 of the first member 50a, and forms an internal flow path 53 together with the first member 50a.

In this embodiment, two inner wall portions 57 are provided on the inner surface of the portion of the second member 50b that constitutes each comb tooth 52. The two inner wall portions 57 are wall-shaped portions that face each other with an interval between them. The arrangement and height of the two inner wall portions 57 are designed so that they fit inside the groove portion 56 of the first member 50a, as shown in FIG. As a result, the portions of the plurality of comb teeth 52 forming both sides of each comb tooth 52 form a double wall, so that the airtightness of the internal channel 53 is easily maintained.

Returning to FIG. 1, the operation section 60 includes a first plate-like part 60a and a second plate-like part 60b. The first plate-shaped portion 60a and the second plate-shaped portion 60b are plate-shaped portions extending from two mutually opposing wall portions of the mounting portion 40, respectively. The first plate-like part 60a and the second plate-like part 60b extend toward the side of the mounting part 40 opposite to the side on which the comb part 50 is mounted. In the state in which the comb part 50 is attached to the attachment part 40, the first plate-like part 60a and the second plate-like part 60b are parallel to the parallel direction line C mentioned above. Moreover, the first plate-like part 60a and the second plate-like part 60b are configured to be able to be displaced relative to the mounting part 40 so as to approach each other by external force.

When the applicator 3 is attached to the discharge container 2, the discharge container 2 is configured to be located between the first plate-shaped part 60a and the second plate-shaped part 60b with a space therebetween. There is. Furthermore, when the first plate-like part 60a and the second plate-like part 60b are pressed from the outside, the mounting part 40 and the comb part 50 move the first plate-like part 60a and the second plate-like part 60b against the mounting part 40. With the displacement, the position is lowered toward the operating section 60 (that is, toward the discharge container 2). As a result, each stem of the first accommodating part 21 and the second accommodating part 22 is pushed down, and the coating agent is discharged from the discharge container 2. As described above, the coating agent discharged from the discharge container 2 is discharged to the outside from the discharge port 55 of the comb portion 50 through the confluence channel and the internal channel 53.

[2. Effect】
As shown in FIG. 8, the user can apply the lubricant to the roots of the hair by discharging the lubricant from the applicator-equipped discharge container 1 and lifting the hair. Note that in FIG. 8, illustration of hair is omitted.

Specifically, the user grasps the dispensing container 2 and the operating section 60 in the dispensing container with applicator 1, and aligns the tips 522 of the plurality of comb teeth 52 along the hairline with the comb section 50 side facing the top of the head. . Then, the user presses the operating part 60 to discharge the liniment from the discharge port 55 of each comb tooth 52, and while keeping the tip 522 of each comb tooth 52 along the scalp, the user moves the comb portion 50 toward the top of the head. move. That is, the user combs the hair while discharging the liniment.

With this operation, the plurality of comb teeth 52 move toward the top of the head while parting the hair. During the movement process of the plurality of comb teeth 52, the coating agent discharged from the discharge port 55 is applied to the portion of the hair sandwiched between the comb teeth 52. More specifically, since the discharge port 55 is formed at the tip 522 of each comb tooth 52, the liniment is applied to the portion of the hair sandwiched between the tip portions 522 of the comb teeth 52. Therefore, when the comb portion 50 is moved while keeping the tip portion 522 along the scalp, the liniment is selectively applied to the root portion of the hair.

In the dispensing container 1 with an applicator, the distal end portions 522 of the plurality of comb teeth 52 are arranged in an arch shape when viewed from the distal end portion 522 side. Therefore, each tip portion 522 easily follows the roundness of the head, and each tip portion 522 is unlikely to be lifted off the scalp during the movement process of the plurality of comb teeth 52. In particular, the shape and arrangement of the plurality of comb teeth 52 such that all of the tips 522 are not located on the same plane makes it easy to accommodate individual differences in the degree of roundness of the head. Since each tip portion 522 is less likely to be lifted from the scalp, it becomes easier to selectively apply the liniment to the root portion of the hair.

Moreover, the discharge container 1 with an applicator has a shape in which each of the plurality of comb teeth 52 extends while being curved. For this reason, it is possible to make the tip portion 522 of each comb tooth 52 lie along the scalp while the discharge container 2 is laid down against the scalp. Furthermore, in the process of combing the hair, the distal end 522 side of each comb tooth 52 advances along the scalp before the proximal end 521 side. These prevent the plurality of comb teeth 52 from getting caught in the hair while combing the hair from the hairline to the top of the head.

Further, in the discharge container 1 with an applicator, the aforementioned dimension M of the plurality of comb teeth 52 is 25 mm or more, and the comb teeth 52 are designed to be longer than those of a general applicator. This increases the area between the comb teeth 52, making it possible to hold more hair between the comb teeth 52. In the operation of combing the hair, the more the comb teeth 52 move from the hairline to the top of the head, the more the amount of hair held between the comb teeth 52 increases, and when the amount of hair that can be held between the comb teeth 52 is exceeded, each comb tooth The tip portion 522 of the comb 52 tends to float away from the scalp, or the plurality of comb teeth 52 tend to get caught in the hair and become stuck. However, in the applicator-equipped discharge container 1, the dimension M of the plurality of comb teeth 52 is designed so that the amount of hair that can be held between the comb teeth 52 increases as described above. Therefore, it is easy to maintain the state in which the tip portion 522 of each comb tooth 52 is aligned with the scalp, continuing from the hairline to the top of the head.

By repeating the above application operation from the hairline all around the head (that is, from the hairline of the front, both sides of the head, and the back of the head) toward the top of the head, apply the liniment to the roots of the hair all over the head. Can be applied.

[3. effect]
According to the embodiment detailed above, the following effects can be obtained.
(3a) In the applicator 3, each of the plurality of comb teeth 52 has a shape that extends while being curved. The arrangement of the tip portions 522 of the plurality of comb teeth 52 is arch-shaped when viewed from the tip portion 522 side.

According to such a configuration, when the applicator 3 is attached to the discharge container 2, the user performs an operation of combing the hair while applying the liniment, thereby applying the liniment to the roots of the hair. can do. In particular, since the arrangement of the distal ends 522 of the plurality of comb teeth 52 is arched when viewed from the distal end 522 side, each distal end 522 can be made difficult to lift off the scalp during the hair combing operation. Therefore, it is possible to make it easier to selectively apply the liniment to the root portion of the hair.

In addition, since each of the plurality of comb teeth 52 has a shape that extends while being curved, it is possible to prevent the plurality of comb teeth 52 from getting caught on the hair and stopping while combing the hair. Therefore, coating efficiency can be improved.

(3b) Each of the plurality of comb teeth 52 has a dimension M along the reference straight line B of 25 mm or more. According to such a configuration, since each comb tooth 52 is longer than that of a conventional applicator, the amount of hair that can be held between the comb teeth 52 can be increased. When the amount of hair that can be held between the comb teeth 52 is large, it is possible to further prevent each tip 522 from floating away from the scalp during the hair combing operation. Therefore, it is possible to more selectively apply the liniment to the roots of the hair. Moreover, when the amount of hair that can be held between the comb teeth 52 is large, it is possible to further suppress the plurality of comb teeth 52 from getting caught on the hair and stopping while combing the hair. Therefore, the coating efficiency can be further improved.

(3c) The height H of the plurality of comb teeth 52 is higher as the comb teeth 52 are located at the center. According to this configuration, compared to a conventional applicator in which multiple comb teeth have the same height, the lubricant can be applied to the rounded head from the hairline to the top of the head. In the coating operation, it is possible to reduce the overlap of areas that can be coated with each stroke. Therefore, the coating efficiency can be further improved.

(3d) The plurality of comb teeth 52 are arranged so that each extending direction spreads radially. According to such a configuration, it is possible to ensure a certain distance or more between the comb teeth 52 at the distal end portion 522 to achieve good combing, and to make the base end portion 521 side compact.

(3e) The applicator 3 of this embodiment has five comb teeth 52. According to such a configuration, the comb part 50 is easy to associate with a human hand, so the method of using the applicator 3 (specifically, applying the lubricant by combing the hair, The orientation of the tool 3, etc.) can be made easier for the user to intuitively understand. The structure in which the height H is higher as the comb teeth 52 in the center of (3c) above, and the structure in which the plurality of comb teeth 52 are arranged so as to spread radially in (3d) above also make the comb portion 50 more reminiscent of a human hand. Contribute to making it easier to do so.

(3f) In the applicator 3, from the viewpoint of improving the ejection properties of the coating material from the ejection port 55, it is preferable that the internal flow path 53 in each comb tooth 52 has a large flow path cross-sectional area. However, if an attempt is made to increase the cross-sectional area of the internal flow path 53 in each comb tooth 52, each comb tooth 52 becomes thicker, and it is conceivable that combing becomes difficult when hair is combed.

On the other hand, in the applicator 3 of this embodiment, the tip portions 522 of the plurality of comb teeth 52 have a tapered shape. According to such a configuration, it is possible to ensure the cross-sectional area of the internal flow path 53 and also achieve good combing performance.

(3g) In the applicator 3, the axial directions of the first accommodating part 21 and the second accommodating part 22 in the dispensing container 2 intersect with the pressing direction of the operating part 60 for discharging the coating agent (main In the embodiment, the discharge container 2 and the operating section 60 are arranged vertically). The first accommodating part 21 and the second accommodating part 22 are arranged side by side, and in this embodiment, their axial directions are parallel to each other.

According to such a configuration, it is easy to press the operation part 60 while holding the discharge container 2 in the same direction as the user holds the discharge container 2 for the hair combing operation. Therefore, the liniment can be discharged without changing the grip during the operation of combing the hair. This point is particularly useful when retouching the back of the head, which is difficult to apply by oneself compared to the frontal and temporal regions.

(3h) The applicator 3 is assumed to be mainly used for retouching. In retouching, only the roots of the hair are dyed, so the amount of liniment used is smaller than when all parts of the hair are dyed. Therefore, it is rare that the coating agent filled in the discharge container 2 is used up all at once, and the coating agent is generally used in several parts. The applicator 3 is also reused. Therefore, in order to prevent the coating agent remaining in the internal channel 53 from solidifying and clogging the internal channel 53, the applicator 3 is cleaned every time hair is dyed.

Therefore, the comb portion 50 is configured to be disassembled into two members, a first member 50a and a second member 50b. A groove portion 56 is formed in the first member 50a. The second member 50b covers the open portion of the groove 56 and forms an internal flow path 53 together with the first member 50a.

According to such a configuration, by disassembling the comb portion 50 into the first member 50a and the second member 50b, the internal flow path 53 can be opened to the outside along the flow direction. Therefore, the ease of cleaning the internal flow path 53 can be improved.

(3i) In particular, in the second member 50b of this embodiment, two inner wall portions 57 are provided on the inner surface of the portion that constitutes each comb tooth 52. The two inner wall portions 57 are configured to fit inside the groove portion 56.

According to such a configuration, the portions forming both side surfaces of each comb tooth 52 become double walls. Therefore, it is also possible to achieve both ease of disassembly of the comb portion 50 and sealability of the internal channel 53.

[4. Other embodiments]
Although the embodiments of the present disclosure have been described above, it goes without saying that the present disclosure is not limited to the above embodiments and can take various forms.

(4a) In the above embodiment, the comb teeth 52 in which the entire region from the base end portion 521 to the distal end portion 522 is curved is described as an example of the comb teeth having a shape that extends while being curved. In addition, a comb tooth whose part of the region in the extending direction is straight is also an example of a comb tooth whose shape extends while being curved. That is, a comb tooth that includes a curved portion whose central axis in the extending direction is curved and a straight portion whose central axis is straight is also an example of a comb tooth that extends while being curved.

(4b) In the above embodiment, the height H of the plurality of comb teeth 52 is higher as the comb teeth 52 are more central. When the number of comb teeth is an odd number as in the above embodiment, the height of the central comb teeth is higher, which means that the height of one comb tooth in the center is the highest, and the height of the one comb tooth in the center is the highest. This means that the height gradually decreases from the teeth to the outer comb teeth. On the other hand, when the number of comb teeth is an even number, the height of the central comb teeth is higher, which means that at least one of the two central comb teeth has the highest height, This means that the height gradually decreases from the book's comb teeth to the outer comb teeth. Note that the plurality of comb teeth do not necessarily have to be as high as the central comb teeth.

(4c) In the embodiment described above, the plurality of comb teeth 52 are arranged so that each extending direction spreads radially. However, the plurality of comb teeth do not necessarily have to be arranged radially in this manner, and for example, at least some of the comb teeth may be arranged parallel to each other.

(4d) In the embodiment described above, the plurality of comb teeth 52 are arranged so as to line up on the linear parallel direction line C. However, the plurality of comb teeth may be arranged so as to line up on parallel direction lines in which at least some of the comb teeth are curved.

(4e) In the above embodiment, the comb portion 50 includes the first member 50a and the second member 50b that form the internal flow path 53. Specifically, the second member 50b covers the open part of the groove 56 of the first member 50a so that the two inner walls 57 fit inside the groove 56 of the first member 50a. Form 53.

In this case, when the two inner walls of the second member fit inside the groove of the first member and cover the open part of the groove, an internal flow path is formed, for example. Ribs may be provided on one of the outer surfaces of the two inner wall portions and the inner surface of the first member, and the other may be provided with a notch and a stopper corresponding to the ribs. Then, in the operation of fitting the first member and the second member, the rib passes over the stopper and fits into the notch, so that the two inner walls of the second member fit inside the groove of the first member. It may also be configured to include

According to such a configuration, when the rib passes over the stopper and fits into the notch, it is possible to give the user a click feeling (feel and sound). The user can tell by the click feeling that the first member and the second member are properly fitted, thereby avoiding using the applicator in a state where they are not fully fitted. can do.

(4f) Also, for example, a groove may be formed on the inner surface of the second member that forms the internal flow path together with the first member, instead of the two inner walls as in the above embodiment. The second member forms an internal flow path together with the first member by covering the open portion of the groove of the first member with the open portions of the groove of the first member and its own groove facing each other. It's okay.

(4g) In the above embodiment, the comb portion 50 is configured to be disassembled into two members, the first member 50a and the second member 50b, but the comb portion is configured to be disassembled into, for example, three or more members. It's okay. Further, for example, the comb portion does not need to be configured to be disassembled into a plurality of members like this.
