Summary of Invention
Technical Problem
-
In the hair dye container described in PTL 1, the applicator, which is attached to the grip through the rod, is attached in a bent state with respect to the axial direction of the rod at the tip end of the rod.
-
In the hair dye container described in PTL 2, the applicator, which is attached to the grip through the rod, is formed in a state in which the entire applicator is curved along the longitudinal direction.
-
Thus, when the applicator is pulled out for application operation from the container body storing the application liquid such as hair dyeing liquid, the applicator mounted in a bent state with respect to the axial direction of the rod (in PTL 1) or the applicator formed in a state in which the applicator is curved along the longitudinal direction (in PTL 2) is apt to be getting caught in the vicinity of the opening of the container; a problem of hindering the smooth operation arises.
-
Such a problem of the applicator getting caught more remarkably occurs in embodiments where a scraper (PTL 1) or a sealing member (PTL 2) is disposed at the opening of the container in order to retain an appropriate amount of application liquid in the applicator.
-
This invention has been made in consideration of the above circumstances and aims to provide a hair dye container that improves operability by eliminating the problem of the applicator getting caught in the vicinity of the opening of the container when the applicator is pulled out from the container body.
Solution to Problem
-
The hair dye container made to solve the problem described above is a hair dye container that includes a container body storing application liquid and a grip of an applicator that is detachably attached to the opening of the container body; the grip, also serving as a cap of the container body, in which an applicator of the application liquid is disposed at the tip end of a rod through the rod, wherein a step in the direction perpendicular to the axis of the rod at a boundary of the rod and the applicator is set less than 1 mm.
-
In a preferred embodiment, the applicator has a plurality of comb teeth that are formed to be arranged in a straight line along the axial direction of the rod on one surface, and an inclined part on the rod is formed to increase the cross-sectional area of the rod toward the standing direction of the comb teeth. A configuration is adopted in which a step in the direction perpendicular to the axis of the rod at the boundary between the inclined part of the rod and the applicator is set to less than 1 mm.
-
In addition, it is desirable to dispose a cylindrical scraper within the container body to adjust the amount of application liquid to be retained by the applicator when the applicator is pulled out of the container body.
Advantageous Effects of the Invention
-
With the hair dye container according to the present invention, an applicator for application liquid is disposed at the tip end of the rod through the rod in a grip of the applicator serving as a cap of the container body.
-
In addition, since the height of the step in the direction perpendicular to the axis of the rod at the boundary of the rod and the applicator is set to less than 1 mm, the problem of the applicator getting caught in the vicinity of the opening of the container when the applicator is pulled out from the container body is overcome, thereby providing a hair dye container having excellent operability.
-
Meanwhile, a configuration in which a plurality of comb teeth are arranged in a straight line along one surface in the axial direction of the rod is preferably used for the applicator.
-
In such a case, it is desirable to form an inclined portion on the rod that increases the cross-sectional area of the rod toward the standing direction of the comb teeth. In addition, by adopting the configuration that the height of the step in the direction perpendicular to the axis of the rod at the boundary of the inclined portion of the rod and the applicator is set to less than 1 mm, the existence of the inclined portion can effectively overcome the problem of the applicator getting caught in the vicinity of the opening of the container body, thereby enabling a hair dye container having good operability to be provided.
-
The configuration for reducing the aforementioned step height can be adopted for the hair dye container to more effectively demonstrate its effect; the dyeing container where a cylindrical scraper is provided inside the container body to adjust the amount of the application liquid retained on the applicator when the applicator is pulled out from the container body.

Description of Embodiments
-
The hair dye container according to the present invention will be described with reference to the drawings of the embodiments below.
-
As shown in Figs. 1 to 3 in overall views, the outer frame of the hair dye container consists of a long, thin container body 1 storing application liquid such as hair dye liquid and a grip 2 serving as a cap of the container body 1, which is detachably attached to an opening 1a at the upper end of the container body 1. That is, the hair dye container consists of the container body 1 and the grip 2 which serves as a cap, forming a thin, long cylinder as a whole.
-
A rod 3 is attached to the inner bottom of the top face 2a of the grip 2 which serves as a cap. By disposing an applicator 4 for the application liquid at the tip end of the rod 3, the grip 2 serves as a grip for the applicator.
-
Thus, as shown in Fig. 1, when the opening 1a of the container body 1 is closed with the grip 2, the applicator 4 is accommodated in the container body 1 and stored, immersed in the application liquid (not shown) in the container body 1.
-
As shown in Figs. 2 and 3, the application liquid, being retained on the applicator 4 through capillary action, can be applied to the eyelashes or hair, etc. by pulling the applicator 4, which is disposed at the tip end of the rod 3, out from the container 1, after removing the grip 2 from the container 1.
-
As shown in Fig. 1, in the present embodiment, a cylindrically-formed scraper 5 is disposed in the opening 1a of the container body 1 to adjust the amount of liquid retained on the applicator 4 when the applicator 4 is pulled out of the container body 1. The configuration details of the scraper 5 will be described later.
-
In addition, a stirrer 6 is accommodated in the container body 1, as shown in Fig. 1, with which the application liquid in the container body 1 can be stirred by shaking the hair dye container while the grip (cap) 2 is mounted to the container body 1.
-
In the drawing example, a stirring ball as a stirrer 6 is accommodated in the container body 1. However, another appropriately shaped stirrer other than a stirring ball can be used as the stirrer 6.
-
The configuration of each of the components with reference numbers 1 to 5, which constitute the hair dye container, will be described by parts.
Container Body 1
-
Fig. 6 shows the container body 1 in a single-article configuration. The container body 1 is formed of a semitransparent resin material, for example, and as previously described, the outer frame has an elongated cylinder shape. In addition, a vicinity of the opening 1a on the upper-end portion of the container body 1 forms a cylindrical neck part 1b with a slightly reduced diameter, and a male thread 1c is formed on the circumference of the neck part 1b. The male thread 1c functions to fasten the grip (cap) 2, which is mounted on the opening 1a.
-
The scraper 5, which will be described later, is inserted into and disposed in the opening 1a.
Holding Part 2
-
The grip 2 also serving as a cap is made of resin material similar to that used for the container body 1, and a cross-sectional view of the grip 2 in a single unit state is shown in Fig. 5.
-
A thin spiral protrusion 2b is formed on the inner circumferential surface near the top surface 2a of the grip 2. This spiral protrusion 2b functions to support the bowl-shaped part 3a inside the inner bottom of the grip 2 without looseness. The bowl-shaped part 3a constitutes the base part of the rod 3, which will be described later.
-
A female thread 2c is formed on the inner circumferential surface on the opening side of the grip 2. The grip 2 is detachably attached to the container body 1 by screwing the female thread 2c into the male thread 1C formed on the inner circumferential surface of the upper end of the neck part 1b of the container body 1.
Rod 3
-
Fig. 7 shows a single-article configuration of a rod 3. The rod 3 is integrally composed of three parts, from base to tip: a bowl-shaped part 3a, a rod body 3b, and an applicator support 3c, all of which are made of resin material.
-
The bowl-shaped part 3a is mounted on the inner bottom of the grip 2 to secure the rod 3 against the grip 2. For this purpose, on the circumferential surface of the bowl-shaped part 3a, multiple ribs 3a1 are arranged at equal distances along the circumferential surface in the axial direction.
-
By pressing the bowl-shaped part 3a into the inner bottom of the grip 2, the multiple ribs 3a1 abut to the spiral protrusion 2b (see fig. 5(C)) formed in the grip 2 and are deformed against each other. Thus, the rod 3 can be mounted to the grip 2 without looseness. (See Figs. 1 and 3)
-
The rod body 3b formed axially is formed standing toward the perpendicular direction from the end surface 3a2 corresponding to the bottom of the bowl-shaped part 3a. An inclined part 3b1 is formed at the front end of the rod body 3b to expand the cross-sectional area of the rod 3 toward the front. Note that the relationship between the inclined part (3b1) and the applicator (4), which will be attached to the tip end of the rod (3), will be described later based on Fig. 1.
-
At the front end of the rod 3, an end face 3b2 is formed perpendicular to the axis. Along the same axial direction as the rod body 3b, an applicator support 3c is formed on the end face 3b2, which has a smaller diameter than that of the rod body 3b.
-
The applicator support 3c is slightly larger in diameter at the root portion of the end face side 3b2. The cross-sectional shape perpendicular to the axial direction is deformedly formed into a semi-circular shape to create a planar surface 3c1 along the axial direction. On the planar surface 3c1, a small protrusion 3c2 along the axial direction is formed.
-
Furthermore, at the tip end of the applicator support 3c, a split groove 3c3 is formed in an axial direction, and a flange 3c4 is formed on its outer circumference.
-
When the applicator 4 is mounted on the applicator support 3c, the end face 3b2 aligns the applicator 4 axially with respect to the rod 3 by contacting to the tip end of the applicator 4. The plane surface 3c1 along the axial direction serves as a rotation stopper for the applicator 4, and the small protrusion 3c2 on the plane surface 3c1 prevents the applicator 4 from loosening (i.e., play occurring) against the applicator support 3c by contacting a part of the inside of the axial bore 4c of the applicator 4, which will be described later.
-
In addition, the split groove 3c3 and the flange 3c4 formed at the tip end of the applicator support 3c, being located in the tip portion of the axial bore 4c of the applicator 4, prevent the applicator 4 from coming off the applicator support 3c.
Applicator 4
-
Fig. 8 and Fig. 9 show a single-article configuration of the applicator 4. In the applicator 4, a plurality of fins 4a formed into a substantially rectangular with slightly rounded corners are arrayed at equal intervals along the longitudinal direction of the rod part 4b at the center. (See Figs. 9(D) to 9(G))
-
As shown in the cross-sectional view in Fig. 9(D), an axial bore 4c is formed to penetrate the rod part 4b at the center of the applicator 4. The applicator 4 is secured to the tip end of the rod 3, which is mounted on the grip 2, by inserting the applicator support 3c, formed at the tip end of the rod into the axial bore 4c.
-
In other words, the base end side bore 4c1 of the axial bore 4c has an inner diameter that is formed largeralong the axis. This base end side bore 4c1 accommodates a deformed-shaped portion that includes a plane 3c1 formed along the axial direction on the applicator support 3c.
-
Furthermore, the inner diameter of the tip side axial bore 4c2 is larger than that of the axial bore 4c of the central portion, forming a step. This tip side axial bore 4c2 accommodates the flange 3c4 formed on the applicator support 3c, thereby securing the applicator 4 at the tip of the rod 3 in a state where the coming-off is prevented.
-
The fins 4a are arranged with an equal spacing along the axis. 4d In other words, in the present embodiment, fins 4a with comb teeth 4d as shown in Fig. 9(E) and fins 4a without the comb teeth 4d as shown in Fig. 9(F) are alternately disposed along the axial direction.
-
Furthermore, the comb teeth 4d protrude in pairs like horns on one plane of the approximately rectangular-shaped fin 4a. The comb teeth 4d are aligned linearly in a view of the axial direction, as shown in Figs. 8(A) and 8(B).
-
The comb teeth 4d function to comb hair when the applicator 4 is rubbed onto objects such as eyelashes and hair. Accordingly, another configuration can be properly employed where the fins 4a with comb teeth 4d (see Fig. 9(E)) are intermittently placed between blocks in which multiple fins 4a without comb teeth (see Fig. 9(F)) are continuously disposed.
-
In the present embodiment, the protrusion height h1 of the comb teeth 4d against the fin 4a is set to 1 mm (See Fig. 9(E)), and the arraying pitch along the axial direction of each fin 4a is set to 0.5 mm. With this configuration, the application liquid is held in place by the capillary effect within the narrow gaps between the adjacent fins 4a.
-
Brims 4e, which have a similar external shape to the fin 4a with comb teeth 4d and are thicker than that of the fin 4a, are formed to sandwich the applicator 4 from the front and the rear in the axial direction at the base and tip ends of the applicator 4. This configuration protects the particularly fragile comb teeth 4d, which are made of thin resin material.
-
Multiple wall parts 4f are formed protruding in the axial direction in parallel to each other at the tip end of the applicator 4. The multiple wall parts 4f formed at the tip end of the applicator 4 can be used to comb and tidy up small sections of the eyebrows and hair locally.
Scraper 5
-
Fig. 10 shows the configuration of a single-article of the scraper 5. The scraper 5 is made of an elastic material such as rubber and formed into a cylindrical shape and is inserted into and mounted on the opening 1a of the container body 1, as shown in Fig. 1, for example. At the tip end of the scraper 5 which is disposed facing the inside of the container body 1, a scraping wall 5a is formed, which can be opened by elastic deformation, and a pass-through wall 5b of the applicator 4 is formed slightly therebehind.
-
A star-shaped slit 5a1 is formed radially formed from the center on the scraping wall 5a. A circular, pass-through hole 5b1, slightly larger than the cross-section perpendicular to the axis of the applicator 4, is formed on the pass-through wall 5b.
-
A diameter-expanded part 5c is formed around the circumference of the tip end of the scraper 5 and serves as a coming-off preventing device from the opening 1a of the container body 1.
-
An annular flange 5d is formed around the rear end of the scraper 5. Due to its positioning at the opening periphery of the container body 1, the flange 5d serves as a packing when the grip 2 of the applicator which serves as a cap is attached to the container body 1.
-
When the applicator 4 is pulled out of the container body 1, this configuration of the scraper 5 enables excess application liquid on the applicator 4 to be scraped off by the scraping wall 5a, which is openable by elastic deformation and enables the amount of the application liquid to be adjusted to an appropriate level.
-
This solves the problem of clothes becoming stained by the application liquid dripping, for example, from the applicator 4 when it is pulled out of the container body 1.
-
Fig. 1 shows the whole view of the hair dye container composed of each part described above; Fig. 1(C) shows the enlarged cross-sectional view of the rod 3 and the applicator 4 mounted on the tip end thereof.
-
As described above, multiple comb teeth 4d, which are formed on the fins 4a, are formed on the applicator 4 to be aligned linearly along one surface in the axial direction of the rod 3.
-
In addition, in the present embodiment, an inclined part 3b1 is formed which increases the cross-sectional area of the rod 3 in the erecting direction of the comb teeth 4d at the boundary between the rod 3 and the applicator 4, as shown in Fig. 1(C).
-
In this case, it is desirable that the step h2, which is perpendicular to the axis of the rod 3 at the boundary between the inclined part 3b1 of the rod 3 and the applicator 4, is set to be smaller, whose value is set to less than 1 mm.
-
As a result, when the applicator 4 is pulled out from the container body 1, due to the presence of the inclined part 3b1 and the smaller value for the step h2, the problem of the applicator 4 being caught in the vicinity of the opening 1a of the container body 1 can be effectively solved, thereby providing a hair dye container with excellent operability.
-
It should be noted that in the embodiment shown in the drawing, the axial line of the applicator support 3c indicated by a long dashed dotted line is shifted as indicated by reference sign S1 to the comb teeth 4d formed position side with respect to the axial line of the rod body 3b indicated by a long dashed dotted line. The shifting amount S1 is set to approximately 0.4 mm.
-
In the present embodiment, as shown in Fig. 1(C), an inclined part 3b1 is formed at the boundary between the rod 3 and the applicator 4, which increases the cross-sectional area of the rod 3.
-
However, in the case without the inclined part 3b1, a similar action and effect to the present embodiment can be obtained by setting the step h2 perpendicular to the axis of the rod 3 at the boundary between the rod 3 and the applicator 4 to be less than 1 mm, thereby providing a hair dye container with excellent operability.
