ABSTRACT:
TECHNICAL FIELD
This invention relates to an apparatus for spraying pseudo hair increasing material (or adding material, or thickening material) suited to be used for supplementing a locally hair-decreased area of the head of a person who needs more hair.
BACKGROUND ART
As well known, there is generally practiced, as related art, a method (apparatus) for temporarily supplementing a locally hair-decreased area of a person's head, as disclosed, for example, in Japanese Patent Examined Publication (Kokoku) No. Sho 48-40036. According to this method, pseudo hair increasing material is applied to a locally hair-decreased area of a person's head through a reticular aperture (or mesh aperture) formed in a container and then, combed or brushed so that the material will come to be intimate with the natural hair. However, the above method (apparatus) cannot obtain the user's satisfaction in respect of effects and easiness of use because the amount of discharged pseudo hair increasing material tends to be irregular and difficult to be sprayed towards the targeted hair-decreased area.
Also, a method (apparatus) as disclosed by Japanese Patent Examined Publication (Kokoku) No. Hei 6-26684 is proposed. According to this method (apparatus), propellant gas is injected directly to pseudo hair increasing material to cause the pseudo hair increasing material to be dispersed under the effect of its injection pressure so that the pseudo hair increasing material will be applied to a hair-decreasing area, and then, the natural hair at the hair-decreasing area with the pseudo hair increasing material applied thereto is combed or brushed so that the pseudo hair increasing material will come to be intimate with the natural hair.
In the above method (apparatus), however, since propellant gas is injected directly to the pseudo hair increasing material to cause the pseudo hair increasing material to be dispersed under the effect of its injection pressure, a discharge amount of the pseudo hair increasing material varies greatly depending on the largeness of the space where the pseudo hair increasing material is dispersed. When liquid gas is used as the propellant gas, the gas is cooled by its evaporation heat and as a result, the pseudo hair increasing material is deposited with frost, thus sometimes resulting in insufficient dispersion of the pseudo hair increasing material. Moreover, this apparatus is incapable of injecting the liquid composition simultaneously.
An apparatus for discharging fine fabric material such as collagen fine fabric, although this is not an apparatus for spraying pseudo hair increasing material, is disclosed by Japanese Patent Unexamined Publication (Kokai) No. Hei 6-142562. In this apparatus, gas is injected into a container in which collagen fine fabrics are stored, so that a jet stream is generated in the container. Then, under the effect of minus pressure caused by the jet stream, the fine fabric material is taken into the jet stream and injected outside together with the jet stream. However, since the container portion in this apparatus comprises a body and a closure portion detachably attached to the body, there is a fear that gas will leak from the engagement portion and that the discharge amount will become irregular due to suction of external air. When the fine fabric material is used up, additional fine fabric material must be supplemented. At that time, however, it is unavoidable that the peripheral area and hand are soiled by the fine fabric material, etc. remained in the container portion, when the additional fine fabric material is supplemented.
DISCLOSURE OF INVENTION
It is, therefore, a first object of the present invention to provide an apparatus for spraying pseudo hair increasing material, in which pseudo hair increasing material in the form of powder or short fabrics can be sprayed to an area of a person's head where hair is locally decreased, continuously and in a stable manner, and pseudo hair increasing material or propellant gas can easily be supplemented without soiling the peripheral area and hand, simply by replacing the container containing pseudo hair increasing material or the container containing propellant gas.
A second object of the present invention is to provide an apparatus for spraying pseudo hair increasing material, in which pseudo hair increasing material in the form of powder or short fabrics can be sprayed to an area of a person's head where hair is locally decreased, continuously and in a stable manner, and an attachment force for attaching the pseudo hair increasing material thus sprayed, to the natural hair and the scalp of a person's head can be increased.
According to the feature of the present invention as recited in claim
1
, the first object can be achieved by providing an apparatus for spraying pseudo hair increasing material including a first container for storing therein pseudo hair increasing material in a form of powder or short fibers, and a second container for storing therein propellant gas, the first and second containers being detachably coupled to each other through a coupler, the second container being provided therein with an injection mechanism for injecting the propellant gas into the first container through an injection nozzle, the first container being formed with a discharge port for discharging the pseudo hair increasing material therethrough, the discharge port having an axis in alignment with that of the injection nozzle, a bore of the discharge port being larger than that of an injection port formed on a distal end of the injection nozzle, through operation of the injection mechanism, the propellant gas from the injection nozzle being injected to thereby cause the pseudo hair increasing material to be discharged from the discharge port towards a predetermined area.
