  1-2 is explanatory drawing of the applicator which concerns on 1st Embodiment, FIGS. 3-4 is explanatory drawing of the applicator which concerns on 2nd Embodiment.

  As shown in FIG. 1, the applicator according to the first embodiment can be impregnated with a coating liquid (indicated by reference numeral 12) accommodated in a shaft body 10, and the coating liquid can be applied to a coating medium (surface to be coated). The present invention relates to an applicator having an applicator 14 that can be applied.

  A coating liquid guiding member 16 made of a synthetic resin molded body capable of guiding the coating liquid from the outer peripheral surface side of the coating section 14 to the tip of the coating section 14 is provided.

  An insertion hole 16a for inserting the application part 14 is formed in the coating liquid guiding member 16 so as to penetrate the opening part on the front end side and the opening part on the rear end side, and around the insertion hole 16a, A coating liquid guiding hole 16b capable of guiding the coating liquid is formed in a groove shape, and the tip side of the coating liquid guiding hole 16b is closed.

  The shaft body 10 is integrally formed in a substantially hollow cylindrical shape so that the hollow penetrates from the front end to the rear end.

  Specifically, the insertion hole 16a and the coating liquid guiding hole 16b have a rear end from the formation part of the coating liquid guiding hole 16b in the vicinity of the opening on the front end side so that they have substantially the same shape in the cross section of the coating liquid guiding member 16. It is formed continuously over the opening on the side.

  The coating liquid guiding hole 16b has a rectangular cross section formed radially outward from the insertion hole 16a with the insertion hole 16a as the center, and a plurality of thin holes opened inward toward the insertion hole 16a. It is comprised by the hole (thin groove). The coating liquid guiding hole 16b is formed by surrounding the insertion hole 16a in a gear shape or a star shape, but the shape of the groove is not particularly specified as long as the coating liquid can be guided.

  The coating liquid guiding hole 16b may be provided anywhere as long as it can open to the insertion hole 16a in the vicinity of the distal end side and guide the coating liquid to the coating part 14 in the insertion hole 16a.

  A tail plug 18 is pressed into the rear end of the shaft body 10 in a liquid-tight manner to prevent leakage of the coating liquid from the rear end. The tail plug 18 has a slightly narrow central portion, opens in the radial direction of the front end portion and the rear end portion, and is in fluid tight contact with the inner peripheral surface of the shaft body 10 (a seal member is provided on the outer periphery of the tail plug 18). Is also good). As a result, in the shaft body 10, the space in the front portion to which the tail plug 18 is fitted serves as a coating solution storage portion 20 that stores the coating solution. The rear ends of the coating part 14 and the coating liquid guiding hole 16b face the front part of the coating liquid storage part 20 so as to come into contact with the coating liquid. In the direct liquid type, the coating liquid storage unit 20 directly stores the coating liquid. On the other hand, in the case of the filling type, the filling liquid is impregnated in the filling stored in the space.

  The application unit 14 is composed of a brush having a plurality of hair tips. The brush may be either natural fiber or artificial fiber. 1 to 2, the application portion 14 is a bundle of resin fibers, and the tip end portion is a tapered shape that is formed thinner toward the tip end, and the rear end is shaped and fixed in a flange shape by heat welding. The Although the material of the application part 14 is not specifically limited, For example, synthetic resin fibers, such as polyamide fibers and polyester fibers, such as PET (polyethylene terephthalate), can be used.

  The tip of the shaft body 10 is formed so that the coating liquid guiding member 16 can be attached (press-fitted or bonded), and outside air and the coating liquid container 20 are provided around the mounting portion of the tip of the shaft body to which the coating liquid guiding member 16 is attached. An air replacement hole 10a is formed so that the coating liquid in the inside can be gas-liquid substituted so that the coating liquid can smoothly flow out to the coating section 14. As shown in FIG. 2, the air replacement hole 10a is formed in a groove shape having a rectangular cross section.

  The coating liquid guiding member 16 has a shape that tapers toward the center at the tip end side and closes the coating liquid guiding hole 16b. As a closing method, it may be formed in a shape closed at the time of molding or once formed in a shape penetrating the coating liquid guiding hole 16b and then deformed and closed by heat welding or the like. The shaft body 10 and the coating liquid guiding member 16 can be made of a liquid-tight material made of various resins such as polyethylene and polyethylene terephthalate.

  According to the applicator according to the first embodiment, in the applicator having the application part 14 that can be impregnated with the application liquid and can apply the application liquid to the application medium, the application is performed from the outer peripheral surface side of the application part 14. The coating liquid guide member 16 made of a synthetic resin molded body capable of guiding the coating liquid to the tip of the section 14 is provided, and the coating liquid guide member 16 is inserted for inserting the coating section 14. A hole 16a is formed to penetrate through the opening on the front end side and the opening on the rear end side, and a coating liquid guiding hole 16b capable of guiding the coating liquid is formed around the insertion hole 16a. Since the leading end side of the guide hole 16b is closed, it is possible to reliably prevent the coating liquid from being scattered from the coating liquid guiding hole 16b when an unexpected situation such as dropping the applicator occurs.

  Further, the formation portion (tip end forming portion) 16b1 of the coating liquid guiding hole 16b on the distal end side so that the insertion hole 16a and the coating liquid guiding hole 16b have substantially the same shape in the cross section of the coating solution guiding member 16. Since it is formed continuously from the opening 16b2 on the rear end side, the structure can be further simplified and the mold in the resin molding can be simplified. In the embodiment, the tip side forming portion 16b1 of the coating liquid guiding hole 16b has a shape in which the tip portion rises from the inner peripheral surface position of the insertion hole 16a to the rear side as shown in FIGS. Is formed. However, the present invention is not limited to this configuration, and if the coating liquid guiding hole 16b is closed on the tip side of the coating liquid guiding member 16, the shape of the tip side forming portion 16b1 may be appropriately formed. It can be formed in a shape that rises in a single or a plurality of steps from the position of the inner peripheral surface of the insertion hole 16a.

  Further, since the coating liquid guiding hole 16b is constituted by a plurality of pores formed radially outward from the insertion hole 16a, the configuration can be simplified.

  A liquid applicator according to a second embodiment will be described with reference to FIGS.

  As shown in FIGS. 3 to 4, in the liquid applicator according to the second embodiment, the tip of the coating liquid guiding hole 16 b in the coating liquid guiding member 16 is attached to the coating liquid by mounting the mounting member 22. The leading end side of the guide hole 16b is closed. The mounting member 22 has a tapered hollow frame shape. Others are the same as those in the first embodiment, and thus the same parts are denoted by the same reference numerals and description thereof is omitted.

  The difference from the first embodiment is that the number of grooves of the coating liquid guiding hole 16b is large (the first embodiment has eight ridges and the second embodiment has 18 ridges) and the front end to the rear end. It is penetrated, the mounting member 22 is mounted on the tip of the coating liquid guiding hole 16b, and the rear end of the coating section 14 is locked in the insertion premises of the coating liquid guiding hole 16b. The air replacement hole 10 a of the shaft body 10 is not in contact with the outer peripheral portion of the application guiding member, and is formed in the front end wall of the shaft body 10.

According to the applicator of the second embodiment, the mounting liquid guiding hole 16b can be easily closed by mounting the mounting member 22 on the distal end side of the coating liquid guiding member 16, and the coating liquid guiding member 16 can be coated with the coating liquid. The coating liquid guiding member 16 can be configured simply, for example, the guiding hole 16b can be similarly formed from the front end to the rear end.
In the present invention, the shape of the mounting member 22 is not limited to the frame shape as in the second embodiment, and the application portion 14 can be inserted and fixed, and the tip end side of the application liquid guiding hole 16b can be closed. If it is a hollow annular structure, the mounting member 22 can be formed by selecting an appropriate shape.

  The mounting member 22 and the coating liquid guiding member 16 are bonded. The bonding method is not particularly specified as long as it can be bonded, such as heat welding or adhesive.

  Here, in the first embodiment and the second embodiment, the number and the cross-sectional area of the air replacement holes 10a are not particularly specified as long as the air replacement in the shaft body 10 can be performed.

  The number and dimensions of the coating liquid guiding hole 16b, the wettability of the inner surface, etc. may be any structure as long as the coating liquid in the coating liquid storage section 20 can flow out toward the coating section 14 by the capillary force. Three or more are desirable for stable outflow of the coating liquid at the time.

  Moreover, in the said 1st Embodiment and 2nd Embodiment, although the application part 14 is a brush (hair tip), the application part 14 can also be made into a synthetic resin molded object. For example, when it is formed integrally with an elastomer, or formed with a fiber bundle core or a sintered body, it can be made thinner than a conventional core. As the material, it is preferable to use a resin molding material made of an elastic member made of a thermoplastic elastomer, for example, since there is little residue remaining on the application portion of the application liquid after application. Further, synthetic fibers bonded with a binder, foamable synthetic resin having open cells, sintered metal, and the like can be used. Alternatively, ceramic foam, foam metal, sintered metal porous body, or the like can be used. A synthetic resin molded body provided with a guide portion such as a liquid guide groove can be used.

  The liquid applicator of the present invention is most preferably a writing instrument such as a brush pen, marker, sign pen, or a cosmetic applicator that directly applies a coating liquid such as a cosmetic lipstick, blusher, or eye shadow to the human skin. In addition, it can be used for a chemical product for applying a fluid chemical, or an applicator for applying an application liquid such as an adhesive or a paint to an article.
