Applicator for Hair and Cosmetic Container with the Applicator

Abstract

A hair care applicator of the present invention is one that can, while combing hair by a comber made up of comb members and a porous application body arranged along the comb members, apply an application liquid in a container being attached to the hair by means of the porous application body. The porous application body of the hair care applicator has a porosity (Vd) falling within a range of 70 to 85%. With this arrangement, the hair care applicator and the applicator-equipped cosmetic container can deliver a suitable supply of application liquid without liquid leakage of the application liquid and, in addition, can assure sufficient application performance, preventing the application liquid or the like from being directly applied to the scalp. Here the porosity is defined as Vd={1−(w/ρsh)}×100, where w is the mass of the porous application body, s is the cross-section of the porous application body, ρ is the mean density of the porous application body and h is the length of the porous application body.

BEST MODE FOR CARRYING OUT THE INVENTION

Referring next to the drawings a hair care applicator of the present invention and a cosmetic container equipped with the applicator will be described in detail based on the best mode for carrying out the present invention. However, the hair care applicator of the present invention and the applicator-equipped cosmetic container should not be limited to the following embodiment.

As shown in FIGS. 1 to 3 an applicator-equipped cosmetic container 1 of the present embodiment, is specifically composed of a comber 30 can a container body 2. Comber 30 as the hair care applicator is composed of comb members 11 and a plate-shaped porous application body 10 arranged with the comb members 11, and is constructed such that an application fluid in a container body 2 can be applied over hair by way of application body 10 as hair is combed with comber 30.

As shown in FIGS. 1 to 3, in cosmetic container 1 resin container body 2 is formed in a cylindrical shape. A rear end 2A of container body 2 is made open so that a reservoir support member 4 shown in FIG. 3 can be inserted and stored into container body 2. Support member 4 supports an application fluid or cosmetic substance. The inner wall at rear end 2A is formed with a thread while a lid member 5B is also formed with a thread so that the two are screw fitted to each other to seal off the opening. Lid member 5B is fixed pressing the rear end 4B of support member 4. Further, in lid member 5B, a lid member 5A for design purposes is attached to lid member 5B.

As the aforementioned reservoir support member 4, the material should not be particularly limited as long as it can support the applicator liquid. For example, padding etc., can be considered.

At the top end 2B of container body 2, a rectangular cylindrical attachment hole 6, socket holes 7 and a threaded portion 9 are formed, the attachment hole 6 being formed at the approximate center. Plate-shaped porous application body 10 is inserted into attachment hole 6 while comb members 11 made of resin are attached to socket holes 7 arranged on both sides. Threaded portion 9 is screw fitted to a threaded portion of an aftermentioned cap. Porous application body 10 is mounted into attachment hole 6 by means of a rectangular support member 12, so that porous application body 10 is arranged in an upright position along the axial direction of container body 2. The proximal end 10A of porous application body 10 is inserted into part of the top end 4B of the aforementioned support member 4 and coupled when it is mounted.

Here, the exterior wall surface of rectangular support member 12 is put in fluid-tight contact with the cylindrical interior wall surface of attachment hole 6, and support member 12 may be fitted either removably to, or totally fixed to, attachment hole 6.

The aforementioned porous application body 10 has a porosity (Vd) ranging from 70 to 85%, particularly preferably from 68 to 85%. Here, the porosity is defined as Vd={1−(w/ρsh) }×100, where w is the mass of the porous application body, s is the cross-section of the porous application body, ρ is the mean density of the porous application body and h is the length of the porous application body). Use of a porous application body 10 having a porosity falling within the above range makes it possible to prevent liquid leakage (forward leakage) of the application liquid and provide a suitable supply of the application liquid to comber 30. If the porosity of the application body is lower than the above range, it becomes difficult to provide a suitable supply of the application liquid from the container. On the contrary, it exceeds the above range, it becomes difficult to prevent forward leakage.

As a porous application body material usable within the aforementioned range, sliver pen cores, felt-like materials, continuous-foamed sponge-like materials, etc., are preferable.

Comb member 11 is formed of a molded member of resin as shown in FIG. 4, and is constructed of a base 13 and a plurality of comb teeth 14 arranged on the top end face of base 13 at regular intervals. Base 13 is formed to be an engaging portion to be detachably engaged into the aforementioned socket hole 7. The distal part of comb tooth 14 is made round. When base 13 and socket hole 7 are engaged with each other, comb members 11 are set in parallel with porous application body 10 mounted in attachment hole 6. In this attached state of comb members 11, the distal ends 14B of comb teeth 14 stick further out from top end 10B of porous application body 10. The amount of projection (L) as shown in FIG. 2, falls within the range of 0.2 to 3.0 mm, and more particularly preferably falls within the range of 0.5 to 2.0 mm.

Upon usage, this amount of projection (L) makes it possible to apply the application liquid to most of the hairs only from their roots without delivering the application liquid to the scalp and others. When the amount of projection is lower than the above range, there is a risk that porous application body 10 directly comes into contact with the scalp. When it exceeds the above range, it is difficult to supply sufficient application to the hair roots.

Also, as shown in FIG. 2 porous application body 10 and comb teeth 14 are preferably arranged closely along side each other so that they are kept out of contact from each other with a spacing S of 5.0 mm or lower, and are particularly preferably arranged apart from each other a distance falling within the range of 0.5 to 3.5 mm. In the present invention, it is not absolutely required that the distance between porous application body 10 and comb teeth 14 should be kept within a fixed distance or smaller, but specifying the distance within the above range makes it possible to prevent the liquid from dirtying the comber as well as to improve the performance of application to hair.

Accordingly, comber 30 as the hair care applicator according to the present invention is constituted of top end 2A of container body 2, porous application body 10, rectangular support member 12 and comb members 11 of base 13 and comb teeth 14.

The aforementioned comber 30 is covered with the aforementioned cap 15. Cap 15 is composed of an inner cap 16, a middle cap 17 and an outer cap 18. Inner cap 16 is formed with an opening portion 22 that abuts the top face of top end 2B of container body 2. Further, in the top end part of inner cap 16 guide hollows 21 with guide projections for separating comb teeth 14 and porous application body 10 and for holding the distal ends of these are formed. A coil spring 23 is arranged inside middle cap 17.

In the thus constructed applicator-equipped cosmetic container 1, since porous application body 10 is used in the structure of comber 30, this structure presents more excellent application performance than that where ejection holes of the application liquid are formed in the comb teeth themselves. Further, specifying for porous application body 10 its porosity within the predetermined range makes it possible to sufficiently prevent liquid leakage (forward leakage) of the application liquid and provide a suitable and uniform supply of the application liquid to comber 30.

Moreover, rows of comb teeth 14 of comb members 11 are arranged close to the thus formed porous application body 10, and the distal ends of the comb teeth of the comb members are projected with the predetermined amount, whereby it is possible to prevent the application liquid from the application body from being directly delivered to the scalp. Accordingly, there is no risk of dirtying the scalp. Further, specifying the closeness within the predetermined range makes it possible to prevent the application liquid from dirtying comb members 11 as well as to assure a good combing condition and a sufficient application performance.

In the above embodiment, top end 2B of container body 2 is formed as part of comber 30 integrally with container body 2 so that the hair care applicator according to the present invention is provided as comber 30 of applicator-equipped cosmetic container 1. However, the present invention should not be limited to this. The top end part of container body 2 may be formed as a detachable lid member so that the hair care applicator may be provided as a separate part from the cosmetic container.

Though in the above embodiment, support member 12 of porous application body 10 and comb members 11 may be detachable from container body 2, they may be configured so as to be fixed to container body 2. In this case, it is preferred that at least one of porous body 10 and comb members 11 is adapted to be detachable. Such a detachable configuration markedly facilitates removal of entangled hairs such as shed hairs sticking to porous application body 10, and eliminates hindrance to handling performance.

Though in the above embodiment it is specified that comb members 11 are made of resin, other materials than this can be used. For example, metal, natural resin, other natural comb material etc. maybe used. However, from an exact sizing viewpoint, resin and metal, which are material having precision formability, are preferable.

In the above embodiment, lid member 5B is removable from reservoir support 4, however lid member SB may be totally fixed thereto, if required, so as not to be detachable.

In the above embodiment, the application liquid is a hair dye but should not be limited thereto. Examples may include a hair liquid, a hair tonic, a hair shining agent for pets and other animals, and others. Also, these application liquids should meet the relationship as to liquid retention force with the aforementioned porous application body.

FIG. 5 shows another mode of an applicator-equipped cosmetic container according to the present invention. Here, for the components of an applicator-equipped cosmetic container 40 shown in FIG. 5, identical or similar to those of the cosmetic container shown in FIG. 1, are allotted with the same reference numerals and their detailed description is omitted.

The difference of applicator-equipped cosmetic container 40 of this embodiment from container 1 of FIG. 1 is that the porous application body is made up of a plurality of pen type porous application elements 41, and these porous application elements 41 are arranged in a row by a binding member 42 along the adjoining comb teeth. These pen type porous application elements 41 have a porosity (Vd) falling within the range of 70 to 85%, similarly to the embodiment shown in FIG. 1. Further, the front ends of comb teeth 14 of comb members 13 are arranged so as to stick further out from the front ends of pen type porous application elements 41, by 0.2 to 3.0 mm while comb teeth 14 and porous application elements 41 are kept out of contact with each other with a spacing of 5.0 mm or lower.

Porous application elements 41 supported by binding member 42 are arranged so as to be apart from each other a distance ranging from 0.4 to 4.0 mm, more preferably, a distance ranging from 0.6 to 2.0 mm. A distance smaller than the above range causes difficulty in combing with a greater number of shed hairs entangled. On the other hand, a distance greater than the above range makes the contactness between hair and pen type porous application elements 41 per unit mass worse, resulting in insufficient application performance.

With the thus constructed applicator-equipped cosmetic container 40, it is possible to provide the same effect as that of cosmetic container 1 shown in FIG. 1, it is also possible to achieve fine application because porous application elements 41 are comb-shaped.

Industrial Usability

With the hair-care applicator of the present invention and its applicator-equipped cosmetic container, when an application liquid (hair dye, hair liquid, hair tonic, etc.) stored in a container is applied to hair while coming the hair with the comber provided for the container body, it is possible to provide a suitable supply of the application liquid without causing any liquid leakage of the application liquid as well as to secure sufficient application performance without causing direct contact of the application liquid with the scalp, hence the invention presents high industrial usability while keeping excellent performance.
