1 is an overall longitudinal sectional view of a liquid supply apparatus according to a first embodiment of the present invention. FIG. 2 is an end view taken along line 2-2 of FIG. It is a longitudinal cross-sectional view showing the state which removed and used the cap of the liquid supply apparatus of FIG. It is a whole longitudinal cross-sectional view of the liquid supply apparatus which concerns on 2nd Embodiment of this invention.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a first embodiment of the present invention. As shown in the figure, a liquid supply apparatus 10 according to the present invention includes a shaft cylinder 12 held by a user and containing a liquid therein.

The shaft cylinder 12 has a cylindrical shape having a first central axis 12a along the longitudinal direction, and the outer cross-sectional shape thereof can have any structure suitable for gripping by the user. For example, it may be circular, but in this example, it has a square shape so that the user's finger can be easily positioned (see FIG. 2). In addition, the square shape may be a triangle or a quadrangle, but if the number of corners is small, the difference in thickness between the thick part and the thin part will increase, and if the number of corners is large, the plane on which the finger is placed will be increased. Since the area is small, a pentagon or hexagon is preferable. Further, in this example, the second central axis 22a, which will be described later, has a pentagonal shape so that an inclined side can be easily understood, within a plane including the first central axis 12a and the second central axis 22a, and the first One ridge line of the shaft cylinder 12 is positioned on the side where the second central axis 22a extends from the central axis 12a.

A tank cylinder 14 is press-fitted into the shaft cylinder 12, and a rear end of the tank cylinder 14 is closed by a tail plug 16 to form a tank portion, and liquid is accommodated in the tank portion. The liquid can be a cosmetic liquid such as an eyeliner or a writing liquid such as a writing ink. The tank cylinder 14 can be an integral part of the shaft cylinder 12.

A liquid storage body 18 having a bellows-like liquid storage groove is inserted on the front end side of the tank cylinder 14, penetrates the liquid storage body 18, and the first central axis 12 a of the shaft cylinder 12 is first. A liquid relay core 20 is extended. The liquid reservoir 18 is for temporarily storing the liquid when the liquid overflows from the tank portion due to the pressure difference.

The front end surface 12b of the shaft cylinder 12 is inclined with respect to the first central axis 12a, and an inclined flange portion 14a that is in contact with the front end surface of the shaft cylinder 12 is formed at the front end of the tank cylinder 14 and further inclined. A connecting portion 14b that is inclined with respect to the first central axis of the shaft tube 12 is formed on the tip side of the flange portion 14a.

When the connecting portion 14b is press-fitted into the tip tool 22, the tip tool 22 is coupled to the shaft cylinder 12 through the connecting portion 14b. It should be noted that the connection between the tip tool 22 and the shaft tube 12 can be screwed, bonded or the like without depending on press-fitting. The tip 22 has a second central axis 22a that has a conical shape and is inclined with respect to the first central axis 12a.

The ball tip 24 is connected to the tip of the tip 22. The ball chip 24 holds a ball 26 at its tip, which becomes a liquid supply unit. The ball 26 can be made of ceramics, stainless steel, or the like.

The ball 26 and the ball chip 24 are on the second central axis 22a and are arranged symmetrically with respect to the second central axis 22a from the viewpoint of mounting or liquid supply. That is, the liquid supply path in the liquid supply unit is symmetrical with respect to the second central axis 22a, or the ball 26 or the ball chip 24 is attached symmetrically with respect to the second central axis 22a. Therefore, it is provided to be inclined with respect to the shaft cylinder 12.

The second liquid relay core 30 is inserted into the rear end of the ball chip 24, and the second liquid relay core 30 extends on the second central axis 22a.

In the connecting portion 14b of the tank cylinder 14 where the first central axis 12a and the second central axis 22a intersect, a liquid holding material 32 made of a porous elastomer such as sponge is disposed. Has been. The front end of the first liquid relay core 20 and the rear end of the second liquid relay core 30 are inserted into the liquid holding material 32 and approach each other.

Also, a cap 36 is detachably attached to the tip tool 22 to protect the liquid supply part at the tip of the tip tool 22 when not in use and prevent drying. The outer cross-sectional shape of the cap 36 is also preferably the same as that of the shaft cylinder 12, which makes it easy to understand the alignment in the circumferential direction on which the cap 36 is attached.

The first liquid relay core 20 and the second liquid relay core 30 are fiber cores made of polyethylene, polypropylene, polyester, or the like, and the liquid penetrates the inside thereof and is guided. The first liquid relay core 20 and the second liquid relay core 30 constitute a liquid derivative bent at the intersection of the first central axis 12a and the second central axis 22a.

In the liquid supply apparatus 10 configured as described above, when used, the cap 36 is removed as shown in FIG. 3, and the liquid supply unit is moved against the surface to be supplied. As a result, the ball 26 rolls, passes from the tank portion through the first liquid relay core 20 and is received by the liquid holding material 32, and from there, the liquid that has passed through the second liquid relay core 30 is transferred to the ball 26. It will be supplied to the surface to be supplied together with rolling.

The user can use one of the pentagonal cylinders 12 with one corner facing downward and placing his finger on the slope facing upward. And it becomes possible to supply the liquid to a to-be-supplied surface by moving a liquid supply part, orienting a liquid supply part downward or horizontally.

Since the liquid supply part is greatly decentered from the first central axis 12a of the shaft cylinder 12, not only when writing on a horizontal plane, but also when supplying liquid to a place such as an inclined or vertical plane or curved surface However, since the location to be supplied need not be on the extension line of the shaft tube, it can be made easy to use.

For example, when liquid is used as an eyeliner, the surface to be supplied is a user's face that is a substantially vertical surface, and the user works the liquid supply unit toward himself / herself. Also in the work, the second central axis 22a and the first central axis 12a are inclined, so that the second central axis 22a is substantially perpendicular to the surface to be supplied, that is, the liquid supply portion is set to the surface to be supplied. Even if it is applied substantially perpendicularly, the shaft cylinder 12 having the first central axis 12a can be inclined with respect to the surface to be supplied. Thereby, the hand holding the shaft cylinder 12 can be brought close to the face, and the hand can be applied to the face as a fulcrum, so that it is easy to work.

According to the present invention, the second central axis 22a can be inclined at an arbitrary angle with respect to the first central axis 12a, and the length of the second central axis 22a is arbitrarily set together with the length of the tip tool 22. Therefore, the liquid supply unit can be greatly decentered from the first central axis 12a. In this example, the tilt angle is 15 °, but the tilt angle can be tilted at an arbitrary angle from 0 ° to 180 °.

Next, FIG. 4 shows a second embodiment of the present invention. In this embodiment, the same or similar parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

In the first embodiment described above, the liquid derivative bent at the intersection of the first central axis 12a and the second central axis 22a is formed by the first liquid relay core 20 and the second liquid relay core 30. In the second embodiment, a single liquid relay core 40 is bent, and the liquid relay core 40 is bent at the intersection of the first central axis 12a and the second central axis 22a.

Further, a liquid holding material 42 is provided around the liquid relay core 40 on the second central axis 22a. In addition, preferably, in the connection through the connection portion 14b between the tip tool 22 and the shaft tube 12, both of the seals are provided between the connection portion 14b and the tip tool 22 to prevent leakage of liquid to the outside. In order to prevent this, an O-ring (seal material) 44 is interposed.

Also in this embodiment, the same operation and effect as in the first embodiment can be obtained, and the number of parts can be reduced because the liquid relay core is composed of a single part.

In the above embodiment, the liquid supply unit is constituted by a ball. However, the liquid supply unit is not limited to this, and may be a brush (brush) or a felt core. The tip of the liquid supply part can be shaped so as not to have rotational symmetry with respect to the second central axis 22a for ease of application, but even in that case, at least 2 in any part including the attachment base part. What is necessary is just to have the symmetry more than the rotational symmetry.

Further, in the above embodiment, the liquid is directly stored in the tank portion. However, the present invention is not limited to this, and the liquid may be stored in an absorbent body such as batting.

In the above embodiment, a part constituted by a plurality of members can be constituted by a single member, or a part constituted by a single member can be constituted by a plurality of members.
