Description

  The present invention relates to a liquid applicator, and is particularly suitable for application when a coating liquid such as mascara or hair dyeing liquid is applied to hair to be applied such as a mascara brush or a hair dyeing brush.

  Conventionally, as this type of liquid applicator, for example, a mascara brush, a mascara having a coating liquid attached to the brush is applied to the eyelashes (see Patent Document 1).

  In this liquid applicator as a mascara brush, as indicated by reference numeral R1 in FIG. 4, a brush body R6 provided at the tip of a shaft R5 fixed to the cap R4 is taken in and out from an outlet R3 of the application liquid container R2. As a result, the brush body R6 is immersed in a mascara as a coating liquid and taken out to the outside.

An annular ironing member R7 made of a flexible rubber material is provided inside the outlet R3, and when the brush body R6 is pulled out from the outlet R3, an extra coating adhered around the brush body R6. By squeezing off the liquid with a squeezing member R7 having a small inner diameter, the coating liquid is configured not to be dropped from the brush body R6 and the shaft R7 taken out to the outside.
JP-A-5-228018

  According to the configuration of FIG. 4, when the brush body R6 is pulled out from the coating solution container R2 as the ironing member R7, the brush bristle material R6A planted on the shaft R5 is pressed by the ironing member R7 in the direction opposite to the drawing direction. The operation is performed so as to fall in the same direction, and the excess coating liquid adhering to the periphery of the brush body 6 is squeezed off, so that the coating liquid can be prevented from dropping off.

  As described above, the brush bristle material R6A falls once when passing through the ironing member R7, but after passing through the ironing member R6, the brush bristle material R6A stands up by its restoring force, so that the coating liquid is applied to the surface of the raised brush bristle material R6A. It remains attached.

  However, since the coating liquid adhering to the surface of the brush bristle material R6A is a relatively small amount, it is desirable that it can be applied to the eyelashes without waste when it is applied to the eyelashes.

  The present invention has been made in consideration of the above points, and intends to propose a liquid applicator having a brush configuration that can apply the application liquid adhering to the brush bristle material to the target liquid without waste. It is.

  In order to solve such a problem, in the present invention, a plurality of yarns constituting the brush bristle material 4 between the two wires 11A and 11B by twisting the two wires 11A and 11B constituting the shaft 3 together. Is a liquid applicator 1 having a brush body 5 holding the thread, and deforms the yarns constituting the brush bristle material 4 so as to protrude in random directions.

  According to the present invention, the yarn constituting the brush bristle material is deformed so as to protrude in a random direction, so that a part of the yarn of the brush bristle material is applied when the hair to be applied is applied by the brush body. After applying the liquid, it is possible to prevent the other application thread from wiping off the applied coating liquid, and thus the coating liquid can be uniformly applied to the application target hair at the required concentration. .

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

  In FIG. 1A, reference numeral 1 denotes a liquid applicator as a whole, and a shaft 3 is projected forward from a tip member 2A that closes the cylindrical support portion 2 inserted and fixed to the cap R4 in FIG. The brush body 5 is formed by projecting the brush bristle material 4 made of a large number of threads 4A outward from the periphery.

  As shown in FIG. 2A, the brush body 5 is prepared by folding a single stainless steel wire to prepare a pair of wires 11A and 11B, and a synthetic resin material (nylon, tetron) between the wires 11A and 11B. 2A made of polyester, PP, etc., and in this state, the turning points of the wires 11A and 11B are fixed, and both ends are twisted in the direction indicated by the arrow b, as shown in FIG. The bristle material 4 is formed by holding and holding a large number of yarns 4A on the spiral holding surface 12 formed between the wire rods 11A and 11B twisted together.

  Thus, an intermediate brush material 13 having a configuration in which the brush bristle material 4 made of the yarn 4A is held on the shaft 3 made of the twisted wires 11A and 11B is obtained, and the protruding direction of the yarn 4A of the brush bristle material 4 from the shaft 3 is obtained. Is deformed so as to protrude in a random direction, and as a result, the brush body 5 shown in FIG. 1A is obtained.

  Here, by projecting and deforming the yarn 4A of the brush bristle material 4 in a random direction, each yarn 4A is continuous in a spiral shape in the tip direction of the shaft 3 as shown in FIG. Rather than projecting while being aligned radially outward from the spiral holding surface 12, each thread 4A projects radially outward, or projects tilted toward the front end or rear end of the shaft 3 Or protruding in a direction along the spiral holding surface 12 between the wires 11A and 11B, or extending in a direction between the extension direction of the spiral holding surface 12 and the distal end direction or the proximal direction of the shaft 3 Such as what to do, it protrudes separately one by one in a state (this is called a random state) that does not give a specific law to the way the yarn 4A of the brush bristle material 4 falls.

  In the liquid applicator 1 having the above-described configuration, the user holds the support portion 2 (FIG. 2A) with his / her finger through the cap R4 (FIG. 1), and removes the brush body 5 from the application liquid container R2 (FIG. 1). By pulling out, the brush body 5 is squeezed by the squeezing member R7 (FIG. 1), so that the application liquid is applied to the eyelashes to be applied with the application liquid adhered to each thread 4A of the brush bristle material 4.

  At this time, the thread 4 </ b> A of the brush bristle material 4 is deformed so as to protrude in a random direction from the shaft 3, and thus the portion of the brush bristle material 4 that touches the eyelashes when applied once to the eyelashes. The application operation can be completed simply by applying the application liquid of the thread 4A to the eyelashes.

  Incidentally, since the order of the thread 4A that touches the eyelashes when the brush bristle material 4 is applied once is based on the fact that the deformation of the thread 4A is random, how to apply to the eyelashes Since it is also random, after all, the application method for the eyelashes when the application operation is repeated is almost uniform each time.

  If the method of deformation of the thread 4A is not random and is deformed with the general law of a mascara brush, the thread 4A that touches the eyelashes when the brush bristle material 4 is applied once is applied. Since the order is the order according to the law, the application liquid applied by the groove liquid between the thread 4A first touched and the next thread 4A during one application operation is always determined. Depending on the nature, it is wiped off by the thread 4A repeatedly touched thereafter and removed little by little.

  Actually, the coating solution applied to the eyelashes is averaged on the surface of the eyelashes by the time the application operation is finished with one random thread 4A on average until the next application operation is performed. It adheres smoothly and smoothly.

  When the next lashing operation is performed on the adhered eyelashes, a new coating solution is applied on the coating solution adhered by drying in an even and smooth manner, so that the eyelashes are contacted by the brush body 5. A coating solution having a concentration corresponding to the number of times adheres.

  According to the above configuration, the yarn 4A of the brush bristle material 4 of the brush main body 5 is made to be equal to the eyelash by one application operation by projecting and deforming the brush bristle material 4 of the brush main body 5 in a random direction. By performing the application operation in this manner, the concentration of the application liquid with respect to the eyelashes can be determined by the number of application operations.

  As a comparative configuration, the liquid applicator 1X shown in FIG. 3 with the same reference numerals and suffixes corresponding to those in FIG. 1 is the same as the case of the intermediate brush material 13 described above with reference to FIGS. 2 (A) and 2 (B). Similarly, when a brush body 5X having a configuration in which the wires 11AX and 11BX are twisted between the wires 11AX and 11BX (the yarns 4A are not randomly deformed) is used as the brush body 5X, When the material 4X is formed in a spiral shape, the yarns 4AX of all the brush bristle materials 4X are arranged in a spiral shape so as to protrude radially outwardly with respect to the spiral holding surface 12X.

  Therefore, when the brush body 5X having this configuration is pulled out from the coating liquid container R2 (FIG. 1) and the coating liquid is applied to the eyelashes, the eyelashes among the threads 4AX of the brush bristle material 4X arranged in a spiral shape. After the thread 4AX closest to the lashes touches the eyelashes, among the threads 4AX of the brush bristle material 4X arranged in a spiral shape, the thread 4AX of the brush bristle material 4X on the inner side regularly touches the same lashes. It becomes a state.

  This is because, in one application operation, after the coating solution of the yarn 4AX of the brush bristle material 4X that was first touched is applied to the eyelashes, the same eyelashes are successively applied to the yarns 4AX regularly arranged on the back side. , The result is that the coating liquid first applied to the eyelashes is wiped off by the brush bristle material 4X that is subsequently touched.

  This is because the coating liquid applied to the eyelashes from the thread 4AX of the brush bristle material 4X that was first touched is not yet dried, so that the next thread 4AX touches one after another, so that the applied liquid is wiped off as a result. This is because the coating liquid is not applied repeatedly.

  On the other hand, according to the brush main body 5 having the configuration shown in FIG. 1, the brush bristle material 4 protrudes and deforms in a random direction in the manner of touching the thread 4 </ b> A of the brush bristle material 4 that touches the eyelashes in one operation. As a result, the bristles and grooves of the general mascara torsion brush do not always become regular alternately, so that the wiping operation as shown in FIG. 4 does not occur.

  In the above-described embodiment, the case where the brush body 5X is a straight type with a constant thickness has been described. However, the external shape is not limited to this, and various shapes such as a tapered shape, a drum shape, a gourd type, and a bullet shape are available. Even if the shape is used, the same effect as in the above case can be obtained.

  In the above-described embodiment, the case where the present invention is applied to a mascara brush has been described. However, the present invention is not limited thereto, and other application target hairs other than eyelashes such as application target hairs to be dyed are applied. In this case, the same can be applied.

  The present invention can be used when a coating solution is applied to hair to be coated.
