Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is mainly applied to hair nourishing agents, hair styling agents, etc.
The present invention relates to a cassette-type brush that allows a built-in cartridge to be inserted into a handle of a brush in a cassette-type and brushes hair or the like while using a liquid.

[Prior Art] Conventionally, when brushing hair or the like, a brush is generally used in one hand and a liquid bottle in the other hand, and the brush is used while spraying the liquid on the hair.

According to this method, it is necessary to move both hands at the same time.
Not only was it cumbersome, but it did not match the bristle tips of the brush, which was desired to disperse the waves, resulting in an inefficient brushing operation.

Further, a brush in which a liquid (for example, water) is ejected from the root of the brush so that the liquid (for example, water) can be supplied and a brushing operation can be carried out, for example, in JP-B-59-1541 and JP-B-59-1542. Seen in many. However, these are all complicated in that they have a liquid source outside, or have a liquid supply tank inside but have a pressure supply mechanism and the like, and are high in cost, and are generally used. It cannot be said that it is preferable as a brush used for hair such as hair because of its simplicity and cost.

[Problems to be Solved by the Invention] As described above, in the conventional brushing method using a simple brush, which is most commonly used in the related art, the complexity of both hands at the time of hair styling and the inefficiency of spraying a liquid by a bottle are caused. Not only that, but there are also the troublesome aspects of having to wash your hands after styling. In addition, even when carrying it on a trip or the like, you must bring both the liquid bottle and the brush.

Furthermore, the one that has a built-in liquid storage tank and supplies the liquid to the brush requires a complicated device such as a pressurizing device, which not only increases the cost but also lacks in simplicity, and is the most commonly used hair. Not suitable as a brush for hair. An object of the present invention is to obtain a simple, inexpensive, and efficient cassette type brush without these problems.

[Means for Solving the Problems] The present invention is a brush in which a cartridge of an atmospheric pressure type in which a pressure inside a cartridge containing a pre-cure solution is enclosed is a cassette type is inserted into a grip portion. A cartridge holding portion having a port for inserting an atmospheric pressure type cartridge from the lower portion into a grip portion of the brush and a guide portion for centering the atmospheric pressure type cartridge in the upper portion, and a cartridge holding portion disposed in the cartridge holding portion. One is a brush thin head, one of which is a pointed tip (preferably a tapered tip), and a liquid thin tube that feeds liquid from the atmospheric pressure type cartridge and an air thin tube that allows air to flow to the cartridge but does not flow. To the atmosphere through the slit valve liquid passageway (hereinafter referred to as liquid passageway) and the passageway of one or the pressing projections, the other of which is in the introduction hole of There is a slit valve air passage (hereinafter referred to as air passage) through which each passage is conducted when the pressing protrusion is pressed by a finger or the like, and when the pressing is released, each spring is provided by a release spring provided at the end. The present invention proposes a cassette type brush having a slit valve whose passage is closed.

[Operation] By holding and holding an atmospheric pressure type cartridge containing a liquid in a cassette type handle, a proper grip thickness of the handle can be guaranteed and it can be held by the other hand. It was possible to operate the liquid bottle that had been used with one hand.

Moreover, the combination of the liquid thin tube and the air thin tube allows the liquid to flow out very smoothly during the operation.

A slit valve having a special structure can supply a required amount of liquid to a brush bristle base when required, by a simple operation with one fingertip, by its operation.

The operational effect of the present application is characterized by (a) the operational effect of using the atmospheric pressure type cartridge (b) the effect of increasing the resistance (interface resistance) by narrowing at least a part of the inner diameter of the air capillary tube. That is, the outflow of the liquid from the cartridge is based on the atmospheric pressure, and when the brush is in a free state (unused state), the liquid in the cartridge is disconnected from the outside and does not flow out to the outside. Also, press the pressing protrusion of the slit valve to connect the slit valve fluid passage (6) to the upper conduction passage (10
c) and the liquid thin tube (3), and the slit valve air passage (7) to the air thin tube (4) and the atmosphere respectively, so that the liquid can flow into the brush bristle portion (in use), If the hole that is open to the atmosphere is closed, the liquid will not flow out.

Furthermore, by making at least a part of the inner diameter of the air capillaries overflow, the resistance (interface resistance) can be increased without impairing the rigidity of the air capillaries. The liquid does not flow out.

The cross-sectional area of the narrow overflow part is such that the liquid does not flow out due to the water head pressure generated by the length of the cartridge at 1 atm pressure. By the way, the equivalent internal diameter is preferably about 1 mm or less.
It is 0.6 mm or less.
