Description

  The present invention relates to a liquid application container, particularly a liquid application container including an applicator that also serves as a brush, which is used for applying cosmetics such as an eyeliner in detail.

As this kind of container, a taper cylinder with an upper end opening is erected from the outer surface of the neck of the container body, and the brush protrudes upward from the inside of the taper cylinder. There has been known one in which a liquid oozes out from the inside of a container body along the surface of the hair (Patent Document 1).
JP 2005-67627 Utility model registration No. 2558633

  In the liquid application container of Patent Document 1, there is a possibility that the liquid cannot be applied to the details when the liquid comes out from the base of the brush.

  In order to correct such inconvenience, the present applicant uses a structure in which hollow pipes are bundled to form a brush-like applicator, and liquid is sucked from the base end surface of the applicator and liquid is oozed only from the front end surface. I thought. As a structure similar to this, for example, a brush using thin tubular hairs cut in the tube axis direction is known (Patent Document 2). The purpose is to suck water into the inside (paragraph 0017).

  On the other hand, in the present invention, the hollow pipe is bundled to form a brush-like applicator, and the upper half of the applicator is provided so as to protrude upward from the container body. An object of the present invention is to propose a liquid application container that prevents liquid from leaking, so that the liquid does not adhere to the hand and does not sag and can be easily applied to the details.

The first means is
While standing up the liquid passing cylinder 8 of the upper end opening from the neck 4 of the container body 2,
In the upper part of the liquid passing cylinder 8, the outer peripheral surface of the rod-shaped applicator 20 formed by bundling a plurality of liquid-permeable hollow pipes 22 opened only at both ends is liquid-tightly held,
The suction surface 24 formed by the base end surface of the applicator 20 is directed to the liquid flow path in the liquid passing tube 8, and the application surface 26 formed by the distal end surface of the applicator 20 is directed outward from the applicator 20. Open
The liquid sucked from the suction surface 24 side can be discharged from the application surface 26 side.

  That is, in this means, the distal end portion of the applicator formed by bundling a plurality of hollow pipes is positioned in the liquid passing cylinder, and the distal end portion of the applicator is protruded outward from the liquid cylinder. The liquid is not leaked to the outside from a portion other than the surface.

  The “liquid passing tube” has a function of supporting the applicator and supplying a liquid to the applicator. The liquid passing cylinder may be erected from the upper inner surface or the outer surface of the neck as a separate body from the neck, or may be formed integrally with the neck.

  The “applicator” is configured by bundling an appropriate number of hollow pipes for passing through an eyeliner or the like. These hollow pipes may be bundled by tightening a liquid passing tube, or each hollow pipe constituting the applicator may be bundled using a fixing tool such as an adhesive or an adhesive tape. Here, the base end face of the applicator is formed by the base end faces of all the hollow pipes, and the tip end face of the applicator is formed by the front end faces of all the hollow pipes. The tip surface may be formed flush, or may be a curved surface or a tapered surface.

  It is desirable that the “hollow pipe” is formed of a material having at least a function as a communication pipe, and more preferably having moderate softness and flexibility as a bristle. As a suitable example, the hollow pipe can be formed as a capillary tube with an outer diameter of about 0.15 to 0.3 mm. The inner diameter and length of the hollow pipe are set to a size that allows the liquid to permeate depending on the viscosity of the content liquid.

The second means includes the first means, and holds the intermediate portion in the vertical direction of the applicator 20 at the upper part of the liquid passing cylinder 8, and the applicator part 20a below the holding part. At least the outer peripheral surface is hardened with a fixture such as an adhesive or an adhesive tape.

  In this means, the outer peripheral surface of the applicator part below the holding part (referring to the applicator part held by the liquid passing tube and the applicator part below the applicator part) is fixed to a fixture such as an adhesive or an adhesive tape. This prevents the liquid from entering from the outer peripheral surface. In addition, you may make it harden to the inside of the applicator part below a holding location with an adhesive agent. As the fixture, in addition to the adhesive tape, a ring of rubber, string, resin, or the like can be used.

    The third means includes the first means or the second means, and the hollow pipe portions can separate the applicator portion 20b above the holding portion by the upper part of the liquid passing tube 8 from each other. It is formed on the brush part.

    If the tip of the applicator is bound, the brushing effect cannot be obtained when the target surface is applied, the feeling of use becomes worse, and it is difficult to apply a small amount of liquid in a narrow area. Therefore, in order to ensure the function as the brush portion or the brush portion, the applicator portion above the holding portion can be separated from each other. “Separable from each other” means that the portions are not bundled and spread when pressed against the target surface.

    The fourth means includes any one of the first means to the third means, and the liquid passing tube 8 includes a bottomed base tube portion 10 fitted in the neck portion 4 and the base tube portion 10. A through-hole 12 drilled in a part of the cylinder wall of the base cylinder part 10 is formed so as to be openable and closable by raising and lowering the front cylinder part 14 with a front cylinder part 14 having a lower end fitted to the inner surface of the cylinder part so as to be movable up and down. In addition, the applicator 20 is held by the tip tube portion 14.

  In this means, the liquid passing cylinder is provided so that the through hole, which is a communication hole between the inside of the container body and the applicator, can be opened and closed by raising and lowering the leading cylinder part relative to the base cylinder part. From the outer surface of the front tube portion, an integral or separate mounting tube can be suspended and fitted or screwed to the outer surface of the neck portion of the container body.

The fifth means has any one of the first means to the fourth means, and projects a large number of application hairs 28 that are more flexible than the hollow pipes from the application surface 26.
These coating hairs can be projected from the tip of each hollow pipe over the entire coating surface. The hair for application can be made thinner than each hollow pipe.

The invention according to the first means has the following effects.
The applicator 20 bundles the hollow pipes 22 and discharges the liquid only from the application surface at the tip of the applicator 20. Therefore, the applicator 20 is suitable for a small amount of application and can be easily applied to a fine place.
○ Since the outer peripheral surface of the applicator 20 is held in a liquid-tight manner by the liquid passing tube 8 erected from the container body neck 4, the liquid leaks from between the applicator 20 and the upper end of the liquid passing tube 8, and the container It is possible to prevent the outer surface of the camera from being soiled or adhered to the user's hand.

  According to the invention relating to the second means, since at least the outer peripheral surface of the applicator portion 20a below the holding position by the liquid passing tube 8 is hardened by a fixing tool such as an adhesive or an adhesive tape, Liquid leakage from the applicator 20 can be prevented more reliably, and attachment to the liquid passing cylinder is also easy.

  According to the invention relating to the third means, since the applicator portion 20b above the holding portion is the brush portion, the usability is good.

  According to the invention relating to the fourth means, the liquid passing cylinder 8 can be opened and closed with the through-hole 12 formed in the base cylinder part 10 by raising and lowering the front cylinder part 14 with respect to the base cylinder part 10. Therefore, when not in use, the communication between the container body and the applicator can be blocked.

  According to the fifth aspect of the invention, since a large number of application hairs 28 that are softer than the hollow pipes are projected from the application surface 26, a soft feel can be obtained when the target surface is applied.

  1 to 4 show a liquid application container according to the first embodiment of the present invention.

  This container includes a container body 2, a liquid passing cylinder 8, an exterior cylinder 18, and an applicator 20.

  The container body 2 erects a neck portion 4 having an upper end opening from a trunk portion through a shoulder portion. Further, an inward flange 6 projects from the inner surface of the upper end of the neck.

  The liquid passing cylinder 8 is formed of a base cylinder part 10 and a leading cylinder part 14. The base tube portion 10 has a bottomed cylindrical shape in which a collar portion at the upper end of the tube wall is placed on the upper surface of the inward flange 6 and is suspended in the neck portion 4. A through hole 12 is formed in the lower part of the cylinder wall of the base cylinder part 10. The front tube portion 14 is slidably fitted in the lower portion of the base tube portion 10 and has a tapered upper portion with a small tip. Further, an outward flange 16 protrudes outward from the outer surface of the intermediate portion in the vertical direction of the front tube portion.

  The outer cylinder 18 is formed by projecting a small-diameter upper half 18b from a large-diameter lower half 18a through a flange-shaped wall, and an outer flange 16 is fitted to the inner surface of the upper half, and the lower half Is screwed onto the neck 4 of the container. Further, the upper end portion of the outer cylinder 18 is inclined upward and inward and is brought into contact with the outer surface of the front cylinder portion 14.

  The applicator 20 has a large number of hollow pipes 22 of the same length bundled in a rod shape, and has an intermediate portion in the vertical direction held liquid-tightly by the upper end portion of the front tube portion 14. The applicator portion 20a below the holding portion is hardened with an adhesive, so that the entire applicator can be integrally mounted in the liquid passing tube 8. In addition, the applicator portion 20b above the holding portion is formed in a brush portion in which each hollow pipe 22 can be bent or deformed independently without being hardened with an adhesive or the like. FIG. 3 is a partially omitted cross-sectional view of the applicator. However, for the convenience of drawing, the outer diameter of the hollow pipe 22 is drawn in a larger ratio than the diameter of the applicator 20 represented by a dotted line. Although the illustrated hollow pipe has a circular tube shape, the shape thereof can be changed as appropriate. In the illustrated example, the lower end surfaces of the hollow pipes 22 are flush with each other to form a suction surface 24 that sucks up the liquid in the liquid passing cylinder 8. Further, the upper end surfaces of the hollow pipes 22 are also flush with each other to form the application surface 26.

  In the above configuration, when the outer cylinder 18 is rotated from the state shown in FIG. 1, the front cylinder portion 14 rises as shown in FIG. The liquid in the container body 2 enters the liquid passing cylinder 8 through the through holes, and further enters the hollow pipes 22 from the suction surface 24. Each hollow pipe guides the liquid to the application surface 26 of the applicator without leaking the liquid in the middle, so that it can be applied from the application surface 26 to the target surface as shown in FIG.

  FIG. 5 shows a modified example of the first embodiment. On the application surface 26 side of the applicator 20, the application hairs 28 that are more flexible than the hollow pipes are raised from the end surface of each hollow pipe 22. The hair for application may be integral with the hollow pipe or may be separate. When formed as a separate body, the root portion of the coating hair 28 is preferably attached to the outer peripheral surface of the tip portion of the hollow pipe so as to be sandwiched between the hollow pipe and the hollow pipe.

  FIG. 6 shows a second embodiment of the present invention. In the present embodiment, the front tube portion 14 and the outer tube 18 of the liquid passing tube 8 are integrally formed, and other structures are the same as those in the first embodiment.
