Description

[0019] In the following description, with reference to the drawings, the same reference numerals are assigned to the same or similar components having the same function, and overlaps in the description are omitted.

[0020] (First group of embodiments) As illustrated in FIGS. 1 and 2, a coating material supply container 1 has a satisfactory appearance in which a general shape forms an elongated round stick shape as in a writing implement, and a cap C (reference FIGS. 12A and 12B) is mounted thereon. The coating material supply container 1 includes a solid coating material M. For example, the coating material M may include a stick-shaped cosmetic material, but may also include a drawing material. The coating material M may include an eyebrow makeup, and the coating material supply container 1 may include an eyebrow makeup supply container.

[0021] For example, the coating material supply container 1 includes a tubular container 2 (also referred to as a “container body” herein) including a distal tube 3 configuring a container front portion and a container main body 4 configuring a container rear portion, a movable body 5 housed inside the container 2, a female screw member 6 housed inside the container main body 4, a spring member 7 disposed behind the female screw member 6, a tubular tip cap 8 extending, in an axial direction, toward the rear of the container main body 4 and inside the container main body 4, and an intermediate tube 9 located between the distal tube 3 and the container main body 4.

[0022] In the present description, an “axial line” represents a center line extending forward and backward of the coating material supply container 1, and an “axial direction” represents a forward and backward direction and a direction extending along an axial line L (reference to FIG. 3). A coating material supply direction M is defined as a forward direction (forward moving direction), and a direction opposite thereto is defined as a backward direction.

[0023] Overall, the distal tube 3 has an elongated tubular shape extending in the axial direction. A front end portion 3a of the distal tube 3 has a distal tube inclination surface 3b (also referred to as “end surface” herein) inclining toward the axial direction. An opening portion 3c through which the coating material M is exposed is formed in the front end portion 3a of the distal tube 3. The opening portion 3c has a shape in which one side of a side surface of the distal tube 3 is cut out, and extends obliquely rearward from a front end 3d to the distal tube 3. The front end portion 3a indicates a prescribed region at a front side of the distal tube 3 including the front end 3d. The distal tube 3 will be described in detail. further away.

[0024] The intermediate tube 9 has a front side portion 9a inserted into the distal tube 3 from the rear, a flange portion 9b extending outwardly, and a rear side portion 9c located behind the flange portion 9b and inserted into the container main body 4 from the front. The intermediate tube 9 is fixed to the distal tube 3 in a state where the front side portion 9a is inserted into the distal tube 3. The rear side portion 9c has a tubular shape, and the female screw member 6 is inserted into the rear side portion 9c from the rear. The female screw member 6 is formed in a substantially cylindrical shape. A female screw 6a configuring one side of a screw portion 10 is disposed on a front side of an inner peripheral surface of the female screw member 6, and a movable body 5 is screwed into the female screw 6a.

[0025] Overall, the movable body 5 has a round stick shape. The movable body 5 is located inside the distal tube 3, the intermediate tube 9, the female screw member 6 and the spring member 7, and extends in the axial direction. The movable body 5 is movable in the axial direction relative to the distal tube 3, the intermediate tube 9, the female screw member 6 and the spring member 7. An outer peripheral surface of the movable body 5 includes a male screw 5a configuring the other side of the screw portion 10.

[0026] A ratchet mechanism 12 which only allows the supply of the coating material M by allowing the relative rotation of the distal tube 3 and the container main body 4 in only one direction is disposed between the female screw member 6 and the spring member 7. For example, the ratchet mechanism 12 is formed by using projections disposed at the front end of the spring member 7 and holes disposed at the rear end of the female screw member 6. The projections project outward in the axial direction from the front end of the spring member 7, and are juxtaposed with each other along the circumferential direction. The holes are disposed at the rear end of the female screw member 6 having a tubular shape, and can engage (click) respectively with the projections to provide a ratchet function.

[0027] The spring member 7 is formed in a tubular shape. The spring member 7 has a function of protecting the coating material supply container 1 by absorbing or reducing an impact transmitted to the interior of the coating material supply container 1 when an external force is applied such as when the coating material supply container 1 is dropped. For example, the front end of the spring member 7 is pushed rearward from the rear end of the female screw member 6 via the projections and holes described above. The spring member 7 includes a front side tube portion 7a being contiguous with the female screw member 6, a rear side tube portion 7b engaging the inner surface of the container main body 4 around the center in the axial direction of the container main body 4, and a spring portion 7c for connecting the front side tube portion 7a and the rear side tube portion 7b to each other.

[0028] The spring portion 7c may comprise a so-called resin spring which can stretch and contract in the axial direction. The spring portion 7c is formed by using a slit 7d extending spirally along a peripheral surface thereof and allowing the inside and the outside to communicate with each other. When the external force is applied, the spring portion 7c stretches and contracts, thereby relaxing the impact applied to the coating material supply container 1.

[0029] A coating material supporting portion 11 for supporting the coating material M is housed inside the distal tube 3. The coating material supporting portion 11 is interposed between the coating material M and the movable body 5. The movable body 5 is rotatable relative to the coating material supporting portion 11. Overall, the coating material supporting portion 11 has a stick shape extending in the axial direction. The rear side of the coating material supporting portion 11 includes a first tube portion 11a into which the movable body 5 is inserted, and the front side of the coating material supporting portion 11 includes a second tube portion 11b into which the coating material M is inserted. The coating material supporting portion 11 supports the coating material M by inserting the coating material M into the second tube portion 11b from the front side.

[0030] Next, the distal tube 3 and the coating material M will be described in detail. As shown in FIG. 3, the distal tube 3 has inside a first housing space 3e and a second housing space 3f which house the coating material M. The first housing space 3e is disposed behind the second housing space 3f, and houses the coating material M and the coating material support portion 11. The second housing space 3f is located at the front side of the first housing space 3e, and is narrower than the first housing space 3e. Only the coating material M is inserted into the second housing space 3f. The second housing space 3f communicates with the opening portion 3c of the front end 3d of the distal tube 3.

[0031] As illustrated in FIGS. 3 and 4, the coating material M extends in a major axis direction DI and a minor axis direction D2 inside the distal tube 3. The second housing space 3f has a shape extending in the major axis direction DI and the minor axis direction D2, and maintains the same shape along the axial direction. A width Y1 (length in the major axis direction D1) of the first space of housing 3e of the distal tube 3 is narrower than a width Y2 of the second housing space 3f, and a clearance Z between the coating material M and the distal tube 3 is constant along the axial direction. In this way, the width Y1 of the first housing space 3e is set to be narrower than the width Y2 of the second housing space 3f, and the clearance Z is set to be constant along the axial direction. In this way, it is possible to suppress, reduce or eliminate the shaking of the coating material M inside the distal tube 3.

[0032] The outer surface of the distal tube 3 includes a distal tube inclination surface 3b extending from the above-described front end 3d, and a rear side inclination surface 3g extending rearwardly from the distal tube inclination surface 3b. A boundary line 3n extends between the distal tube inclination surface 3b and the rear side inclination surface 3g. Both the distal tube inclination surface 3b and the rear side inclination surface 3g extend in a direction leaning toward the axial direction. An inclination angle of the distal tube inclination surface 3b with respect to the axial direction is larger than an inclination angle of the rear side inclination surface 3g with respect to the axial direction.

[0033] As shown in FIGS.3, 5 and 6, the coating material M has a distal end M1 (also referred to as “leading edge” herein) which is fed forward from the opening portion 3c and which extends along the major axis direction DI intersecting the axial direction. An outline shape of the coating material M, when viewed from the front end of the container 2, appears to extend perpendicular to the longitudinal axial direction of the coating material feed container in the major axis direction DI associated with a width of the coating material M and the minor axis direction D2 associated with a height of the coating material M. In some examples, the width of the coating material M is greater than the height. A leading edge of the distal end Ml is oriented along the width of the coating material M. In some examples, the distal end Ml has an acute angle shape. The leading edge (Ml) may extend along a plane which is parallel to both the major axis direction (Dl) and the longitudinal axis direction.

[0034] The coating material M has a coating material inclination surface M2 (also referred to herein as an “inclined surface”) extending from the leading edge of the distal end M1 in a direction inclined toward the axial direction. The coating material inclination surface M2 extends in a direction inclined both toward the axial direction and toward the minor axis direction D2. The coating material inclination surface M2 is a surface formed along the distal tube inclination surface 3b of the distal tube 3. For example, the inclination angle of the coating material inclination surface M2 is substantially the same as the inclination angle of the inclination surface of distal tube 3b.

[0035] When viewed from the front side, the shape of the distal tube 3 is circular overall, and the front end 3d has a shape extending in the major axis direction DI. When viewed from the front side, the distal tube inclination surface 3b is disposed on one side in the minor axis direction D2 of the front end 3d, and the shape of the distal tube inclination surface 3b is an oval shape extending in the major axis direction DI and the minor axis direction D2. The distal tube tilting surface 3b is arranged on one side (the upper side in FIG. 6) in the minor axis direction D2 relative to the front end 3d, and the coating material tilting surface M2 is formed on one side in the minor axis direction D2 relative to the distal end ML. The distal tube tilting surface 3b is arranged along an extension line of the coating material tilting surface M2.

[0036] As illustrated in FIGS. 6 and 7, the distal tube 3 has an inner wall surface 3h facing the coating material M, inside the opening portion 3c. The inner wall surface 3b faces a first side surface M3 facing a side in the major axis direction DI of the coating material M. The first side surface M3 has a flat shape. The distal tube tilting surface 3b has a curved ton which curves rearwardly toward the rear end surface 3g or the rear end of the distal tube 3 from the front end 3d located at a first side 31 (reference to FIG. 5) of the distal tube 3 to a second side 3j of the distal tube 3 opposite the first side 3i. The opening portion 3c is formed to extend rearwardly at the rear end of the distal tube 3 from the front end 3d of the first side 3i to the second side 3j.The inner wall surface 3h faces the coating material M of the first side 3i of the distal tube 3, and in some examples the opening portion 3c comprises a curved opening which exposes the coating material M to the second side 3j of the distal tube 3.

[0037] As illustrated in FIGS. 8 and 9, the coating material inclination surface M2 has a curved surface shape which is curved outward so as to form a curved or rounded portion of the coating material M. The coating material inclination surface M2 is curved so as to protrude outward from the coating material M and the distal tube 3. The coating material inclination surface M2 and the distal tube inclination surface 3b are respectively curved surfaces which extend linearly along an acute angle line A both inclined toward the axial direction and toward the minor axis direction D2, and which are curved outward so as to form a curved or rounded portion of the coating material M and the distal tube 3.

[0038] That is, when the acute angle line A having an acute angle with respect to the Axial line L is moved so as to form a curved or rounded portion of the coating material M and the distal tube 3, a trajectory of the acute angle line A forms the coating material inclination surface M2 and the distal tube inclination surface 3b. A second flat side surface M4 is disposed on one side of the coating material inclination surface M2 which is opposite to the first side surface M3. A third flat side surface M5 is disposed on one side in the minor axis direction D2 of the coating material inclination surface M2.

[0039] As shown in FIGS. 10 and 11, the front end 3d of the distal tube 3 is bent outward to form a curved or rounded portion of the distal tube 3. The distal tube tilting surface 3b is curved so as to protrude outward from the coating material M and the distal tube 3. When viewed from the front end 3d, a tilting surface 3p is disposed on an opposite side of the distal tube tilting surface 3b. The tilting surface 3p tilts toward the opposite side of the distal tube tilting surface 3b and the coating material tilting surface M2 with respect to the axial direction. An angle formed between the tilting surface 3p and the distal tube tilting surface 3b is defined as an acute angle. A boundary portion 3q extending rearwardly from the front end 3d is disposed between the distal tube tilt surface 3b and the tilt surface 3p. The boundary portion 3q is.contiguous with the front end 3d, and extends linearly rearward of the distal tube 3 from the front end 3d. .

[0040] The cap C shown in FIGS. 12A and 12B is mounted on the distal tube 3. The cap C is formed in a stick shape extending in the axial direction. The cap C includes a tubular portion CT which is oriented toward the rear and into which the distal tube 3 is inserted from the rear, and a cutting portion C2 located in front of the tubular portion C1. For example, the tubular portion C1 and the cutting portion C2 are integrally molded with each other. An inner peripheral surface of the tubular portion C1 has a plurality of projections C3 engaging the inserted distal tube 3. The distal tube 3 is inserted between the plurality of projections C3 extending in the axial direction, thereby causing the distal tube 3 to engage the cap C.

[0041] The cutting portion C2 includes a distal end portion C4 which has an oval shape when viewed from the front side, and a cutter portion C5 which is located behind the distal end portion C4. A cross-sectional shape when the cutter portion C5 is cut along a plane orthogonal in the longitudinal direction of the cap C is a shape (e.g., a drop shape) including a pointed end portion such that an end portion extending along a major axis of an oval projects in the major axis direction.

[0042] The coating material M can be cut by detaching the cap C from the distal tube 3 and applying the cutter portion C5 to the coating material M. Particularly, the cap C is held with one hand, the cutter portion C5 is moved along the distal tube inclination surface 3b (or the acute angle line A) of the distal tube 3 so as to cut the coating material M. In this way, the coating material inclination surface M2 extending along the distal tube inclination surface 3b is formed, as shown in FIG. 10.

[0043] An example of feeding the coating material M will be described. As illustrated in FIGS. 1 and 2, when the coating material M is fed from the distal tube 3, the distal tube 3 is rotated relative to the container main body 4 in one direction (e.g., clockwise) in a state where the cap G is detached. Then, the distal tube 3, the intermediate tube 9, and the female screw member 6 are rotated synchronously, and the container main body 4, the spring member 7, the tip cap 8, and the movable body 5 are rotated synchronously. In this way, a screwing operation of the screw portion 10 configured to include the female screw 6a of the female screw member 6 and the male screw 5a of the movable body 5 is performed to make the movable body 5 advance.

[0044] As the movable body 5 advances, the coating material M is caused to protrude forward from the opening portion 3c of the distal tube 3, thereby discharging the coating material M. As the coating material M is applied to a coating target portion, coating is performed using the coating material M. The distal tube 3, the container main body 4, the movable body 5, the female screw member 6, the spring member 7, the tip cap 8, and the intermediate tube 9 which are described above configure a feeding mechanism for feeding the coating material M in the axial direction.

[0045] As described above, the coating material supply container 1 includes the solid coating material M extending in the axial direction, and the distal tube 3 for holding the coating material M. As shown in FIGS. 3, 5 and 6, the shape of the coating material M when viewed from the front side is a shape extending in the major axis direction DI and the minor axis direction D2. When viewed from the front side, the coating material M has a shape extending longer in length in the major axis direction DI. The distal end M1 of the coating material M has an acute angle ton, and extends in the major axis direction DI. Accordingly, the distal end Ml of the coating material M extending in the major axis direction DI is applied to the coating target portion, and the coating material M is moved along the major axis direction DI. In this way, a thin line can be finely drawn on the coating target portion.

[0046] Knowing the distal end M1 of the coating material M has a shape extending in the major axial direction D1, for example, compared to a case where the distal end of the coating material has a pyramid shape, it is unlikely that the distal end M1 will be rounded or blunt even if coating is performed or continuously applied to the coating target portion for an extended period of time. Accordingly, when a thin line is drawn, the effort and time for cutting the coating material M can be saved. Therefore, the thin line can be drawn easily.

[0047] Furthermore, in a case where the distal end M1 is rounded or blunt after the coating is continuously performed using the coating material M, the coating material M is advanced slightly so that the cutter portion C5 or a cutter cuts the coating material M along the distal tube inclination surface 3b. In this way, the distal end M1 can easily reproduce the acute angle ton, and a thin line can be easily drawn. Even if the coating material M is polished along the distal tube inclination surface 3b with those having a surface having different roughnesses, such as paper, sandpaper, a film whose surface is treated in uneven relief, or a tissue, it is possible to easily reproduce the distal end M1 having a desired acute angle.

[0048] The distal end Ml extends linearly along the major axis direction Dl. That is, the distal end Ml of the coating material M extends longer in length in the major axis direction Dl. Therefore, if the coating is performed by moving the coating material M along the major axis direction Dl, the thin line can be drawn finely along the linear distal end Ml. Therefore, the thin line can be drawn easily along the distal end Ml.

[0049] The coating material inclination surface M2 is formed along the distal tube inclination surface 3b, and is formed on one side in the minor axis direction D2 relative to the distal end M1. That is, the coating material inclination surface M2 is formed on one side of the distal end M1 of the coating material M, and the coating material inclination surface M2 is formed on the side of the distal tube inclination surface 3b. Accordingly, the cutting tool such as the cutter is moved along the distal tube inclination surface 3b so as to cut the coating material M. In this way, the coating material inclination surface M2 can be formed easily. Therefore, it is possible to easily form the coating material M by including the distal end M1 and the coating material tilt surface M2 which can finely draw the thin line.

[0050] The coating material inclination surface M2 and the distal tube inclination surface 3b are respectively curved surfaces which extend linearly along the acute angle line A leaning toward the axial direction, and which are curved outward so as to form a rounded portion of the coating material M and the distal tube 3. Therefore, since the coating material inclination surface M2 and the distal tube inclination surface 3b are the curved surfaces which are curved outward, the distal end M1 of the coating material M may have a curve shape.

[0051] The distal end M1 has a curve shape which is bent outward so as to form a rounded portion of the coating material M. The distal end M1 has a curved shape so as to protrude outward from the coating material M and the distal tube 3. Accordingly, since the distal end M1 has the curve shape which is bent outward, a short thin line or a long thin line can be drawn more easily by applying the distal end M1 to the coating target portion. That is, since the distal end M1 bends outward, coating is performed along the distal end M1. In this way, it is possible to draw a short hair-thin line or a long hair-thin line more easily.

[0052] The distal tube 3 has the opening portion 3c for holding the coating material M, and the opening portion 3c is formed so as to extend from its front end 3d to one side and to the rear side in the major axis direction D1. Therefore, since the opening portion 3c extends to one side in the major axis direction D1, the inner wall surface 3h facing the coating material M can be arranged to the other side in the major axis direction D1 of the opening portion 3c.

[0053] The opening portion 3c has the inner wall surface 3h facing the coating material M, on the other side in the major axis direction D1. Therefore, when coating is performed using the coating material M or when the coating material M is cut, even if the external force is applied to the coating material M, the loss and breakage of the coating material M can be suppressed, reduced or eliminated. That is, when the external force is applied to the coating material M, the coating material M is pushed against the inner wall surface 3h, and the inner wall surface 3h holds the coating material M. In this way, it is possible to prevent the loss and breakage of the coating material M.

[0054] (Second group of embodiments) Next, a coating material supply container 21 will be described with reference to FIGS. 13 to 18. The configuration of a distal tube 23 and a coating material N are distinguished from the first group of embodiments. As illustrated in FIGS. 13 and 14, the coating material supply container 21 includes the distal tube 23 configuring the front container portion, a tubular container 22 including the container main body 4 configuring the rear container portion, the movable body 5 housed inside the container main body 22, the female screw member 6 housed inside the container main body 4, the spring member 7 disposed behind the female screw member 6, the tubular tip cap 8 extending in the axial direction behind the container main body 4 and inside the container main body 4, and the intermediate tube 9 located between the distal tube 23 and the container main body 4. Hereinafter, a repeated description of the coating material supply container according to the first group of embodiments will be suitably omitted.

[0055] As illustrated in FIG. 15, the outer surface of the distal tube 23 includes a distal tube tilt surface 23b (also referred to herein as an “end surface”) extending from a front end 23d of the distal tube 23, and a rearward side tilt surface 23g extending rearwardly from the distal tube tilt surface 23b. A boundary line 23n extends between the distal tube tilt surface 23b and the rearward side tilt surface 23g. Both the distal tube tilt surface 23b and the rearward side tilt surface 23g extend in a direction tilting toward the axial direction. The inclination angle of the distal tube inclination surface 23b is larger than the inclination angle of the rear side inclination surface 23g.

[0056] As illustrated in FIGS. 15 and 16, the coating material N is fed forward from an opening portion 23c of the distal tube 23, and has a distal end NI (also referred to as “leading edge” herein) extending along the major axis direction DI intersecting the axial direction. The shape of the coating material N when viewed from the front side is a shape extending in the major axis direction DI and the minor axis direction D2. The distal end NI has an acute angle shape. The distal end NI has a linear shape extending in the major axis direction D1, and the thickness of the distal end NI is gradually reduced from one side (the left side in FIG. 16) to the other side (the right side in FIG. 16) in the major axis direction D1.

[0057] The coating material N has a coating material slope surface N2 extending from the distal end NI in a direction inclined toward the axial direction. The coating material slope surface N2 (also referred to as a “sloped surface” or “second inclined surface”) extends in a direction inclined toward both the axial direction and the minor axial direction D2. The coating material slope surface of coating material N2 is a surface formed on the part of the distal tube inclination surface 23b of the distal tube 23. For example, the inclination angle of the coating material inclination surface N2 is substantially the same as the inclination angle of the distal tube inclination surface 23b.

[0058] The shape of the distal tube 23 when viewed from the front side is circular overall, and the front end 23d has an oval shape extending in the major axial direction D1 and the minor axial direction D2. When viewed from the front side, the distal tube tilting surface 23b has an oval shape surrounding the front end 23d and extending in the major axis direction D1 and the minor axis direction D2.

[0059] The distal tube tilting surfaces 23b are arranged vertically in pairs with respect to the front end 23d. The distal tube tilting surface 23b and the coating material tilting surface N2 are formed in pairs on both sides in the minor axis direction D2 with respect to the distal end NI. That is, the coating material tilting surface N2 is formed on both sides in the minor axis direction D2 of the distal end NI, and the distal tube tilting surfaces 23b are arranged in pairs so as to extend along the extension line of the respective coating material tilting surfaces N2. For example, the distal tube tilting surface 23b and the coating material tilting surface N2 are arranged vertically symmetrically with respect to the distal end N1.

[0060] As illustrated in FIGS. 17 and 18, the distal tube 23 has an inner wall surface 23d facing the coating material N, inside the opening portion 23c. The inner wall surface 23h faces a first side surface N3 which is widened on one side in the major axis direction DI of the coating material N. A curved surface N5 which is curved outwardly of the coating material N is formed between the first side surface N3 and the distal end NI.

[0061] A portion which widens in the distal end NI is contiguous with the first side surface N3 via a curved surface N5. The first side surface N3 has a flat shape, and the curved surface N5 and the distal end NI have a curved surface shape. The distal end N1 is narrowed from one side to the other side in the major axis direction D1, and is curved backward.

[0062] That is, the distal end N1 is curved outward to form a rounded portion of the coating material N as the distal end NI extends from one side to the other side in the major axis direction D1. A second side surface N4 which is widened toward the rear is provided at the end portion of the other side in the major axis direction D1 of the distal end NI. In this way, the coating material N has the first side surface N3 which is widened, the curved surface N5, the linear distal end NI which narrows as the distal end NI tends away from the first side surface N3, and the second side surface N4 which widens as the second side surface N4 tends away from the distal end NI, In this way, a fine line can be drawn using the coating material N,

[0063] The coating material inclination surface N2 is curved on one side and at the rear side in the major axis direction DI from the first side surface N3 toward the second side surface N4. The coating material inclination surface N2 is curved outwardly so as to form a rounded portion of the coating material N from the first side surface N3 toward the second side surface N4. In other words, the coating material inclination surface N2 is curved in a curve shape from the first side surface N3 toward the second side surface N4. The width of the coating material inclination surface N2 is set to be substantially constant from the first side surface N3 to the second side surface N4.

[0064] The front end portion 23a of the distal tube 23 includes the front end 23d described above and a curved surface 23j connecting the front end 23d and the distal tube tilting surface 23b to each other. The front end 23d is a flat surface with respect to the front side, and the curved surface 23j is curved from the front end 23d toward the distal tube tilting surface 23b. The distal tube tilting surface 23b is curved outward from a first side portion 23k having the inner wall surface 23h to a second side portion 23m located at the opposite side in the major axial direction DI of the first side portion 23k. The boundary line 23n between the distal tube tilting surface 23b and the rear side tilting surface 23g is curved outward from the side opening portion 23k toward the second side portion 23m.

[0065] The coating material N of the coating material supply container 21 configured as described above can perform cutting by applying the cutter portion C5 of the cap C to the coating material N. Particularly, the cap C is held by hand, and the cutter portion C5 is moved along the distal tube inclination surface 23b of the distal tube 23 so as to cut the coating material N. In this way, as illustrated in FIGS. 15 to 18, the coating material inclination surface N2 extending along the distal tube inclination surface 23b is formed.

[0066] As illustrated in FIGS. 13 and 14, when the coating material N is supplied from the distal tube 23, the distal tube 23 is rotated relative to the container main body 4 in one direction (e.g., clockwise) in a state where the cap C is detached. Then, the distal tube 23, the intermediate tube 9, and the female screw member 6 are rotated synchronously, and the container main body 4, the spring member 7, the tip cap 8, and the movable body 5 are rotated synchronously. In this way, a screwing operation of the screw portion 10 is performed so that the movable body 5 advances. As the movable body 5 advances, the coating material N is caused to protrude forward from the opening portion 23c of the distal tube 23, thereby discharging the coating material N. As the coating material N is applied to the coating target portion, a portion of the coating material N coats or otherwise marks the coating target portion.

[0067] As described above, the coating material supply container 21 includes the solid coating material N extending in the axial direction, and the distal tube 23 for holding the coating material N. As shown in FIGS. 15 and 16, the shape of the coating material N when viewed from the front side is the shape extending in the major axis direction D1 and the minor axis direction D2. When viewed from the front side, the coating material N has a shape extending more in length in the major axis direction D1. The distal end N1 of the coating material N has an acute angle shape and extends in the major axis direction D1. Accordingly, the distal end NI of the coating material N extending in the major axis direction D1 is applied to the coating target portion, and the coating material N is moved along the major axis direction D1. In this way, a thin line can be finely drawn on the coating target portion.

[0068] In addition, the coating material inclination surface N2 is formed along the distal tube inclination surface 23b, and is formed on both sides in the minor axis direction D2 relative to the distal end NI. Therefore, the coating material inclination surface N2 is formed at both sides of the distal end NI of the coating material N, and the coating material inclination surface N2 is formed on the extension line of the distal tube inclination surface 23b. Accordingly, when the coating material N is cut along the distal tube inclination surface 23b, the coating material inclination surface N2 is naturally exposed at the distal end of the distal tube 23. Therefore, coating can be performed immediately after the coating material N is cut.That is, even if the coating material N is not fed immediately after the coating material N is cut, the coating material N can be used in the coating. Therefore, the thin line can be drawn more easily.

[0069] (Third group of embodiments) Subsequently, a coating material supply container 31 will be described in referring to FIGS. 19z\ and 19B. In the coating material supply container 31, each shape of a distal tube 33 and a coating material P is distinguished from those of the embodiments described above. The outer surface of the distal tube 33 includes a distal tube tilt surface 33b extending from a front end 33d of the distal tube 33 and a rear side tilt surface 33g extending rearward of the distal tube tilt surface 33b.

[0070] The distal tube tilting surface 33b tilts both toward the axial direction and toward the minor axis direction D2, and is curved from the front end 33d toward one side and toward the rear side in the major axial direction D1. The distal tube tilting surface 33b is curved outward so as to form a rounded portion of the distal tube 33. The distal tube 33 has an opening portion 33c through which the coating material P is exposed.

[0071] Similar to the distal tube inclination surface 33b, the opening portion 33c extends in a curved manner from the front end 33d to one side and the rear side in the major axis direction D1. The opening portion 33c has a hill-shaped projection 33e at the side opposite the front end 33d. The projection 33e projects in a direction in which the width of the opening portion 33c narrows. Due to this projection 33e, the width of the opening portion 33c is widest at both ends in the major axial direction D1, and is narrowest at the center in the major axial direction D1. That is, the width of the opening portion 33c is gradually reduced from one end in the major axial direction D1 toward the center in the major axial direction D1.The width of the opening portion 33c gradually widens from the center in the major axial direction Dl toward the other end in the major axial direction Dl.

[0072] A shape of a coating material tilting surface P2 is a shape extending along the distal tube tilting surface 33b and the opening portion 33c. The coating material P has a distal end PI having an acute angle shape and the coating material tilting surface P2 tilting toward the direction extending along the distal tube tilting surface 33b from a distal end PI. The coating material P has recesses P3 extending along the projection 33e of the opening portion 33c, on one side in the minor axis direction D2. The coating material tilting surface P2 is formed by holding the cap C by hand and moving the cutter portion C5 along the distal tube tilting surface 33b.

[0073] As described above, the coating material supply container 31 includes the solid coating material P, and the distal tube 33 for holding the coating material P. The shape of the coating material P when viewed from the front side is a shape extending into the major axis direction DI and the minor axis direction D2. When viewed from the front side, the coating material P has a shape extending longer in length in the major axis direction D1. The distal end PI of the coating material P has an acute angle shape, and extends in the major axis direction D1. Accordingly, the distal end PI of the coating material P extending in the major axis direction D1 is applied to the coating target portion, and the coating material P is moved along the major axis direction D1. In this way, a thin line can be drawn finely on the coating target portion.

[0074] (Fourth group of embodiments) Next, a coating material supply container 41 will be described with reference to FIGS. 20A and 20B. The coating material supply container 41 includes a distal tube 43 and a coating material Q which respectively have different shapes from those according to the embodiments described above. A distal tube inclination surface 43b of the distal tube 43 both inclinates toward the axial direction and toward the minor axis direction D2.

[0075] The opening portion 43c of the distal tube 43 is bent from the front end 43d of the distal tube 43 to one side and the rear side in the major axis direction D1. When viewed from the front side, the opening portion 43c has an oval shape (rounded rectangular shape) extending in the major axis direction D1 and the minor axis direction D2. Both ends in the major axis direction D1 of the opening portion 43c are bent in an are shape. The coating material Q has a distal end Q1 having an acute angle shape and a coating material inclination surface Q2 extending from the distal end Q1 along the distal tube inclination surface 43b. The shape of the coating material inclination surface Q2 is formed along the distal tube inclination surface 43b.

[0076] As described above, the coating material supply container 41 includes the solid coating material Q and the distal tube 43 for holding the coating material Q. The shape of the coating material Q when viewed from the front side is a shape extending in the major axis direction D1 and the minor axis direction D2. The coating material Q has an oval shape extending longer in the major axis direction D1. The distal end Q1 of the coating material Q has an acute angle shape, and extends in the major axis direction D1. Accordingly, the distal end Q1 of the coating material Q is applied to the coating target portion, and the coating material Q is moved along the major axis direction D1. In this way, a thin line can be finely drawn on the coating target portion.

[0077] (Fifth group of embodiments) Subsequently, a coating material supply container 51 will be described with reference to FIGS. 21A and 21B. In the coating material supply container 51, each shape of an opening portion 53c of a distal tube 53 having a distal tube inclination surface 53b and a coating material R having a distal end RI, and a coating material inclination surface R2 are distinguished from those of the fourth group of embodiments. In the fourth group of embodiments, the opening portion 53c and the coating material inclination surface R2 have an oval shape (rounded rectangular shape). In contrast, in the fifth group of embodiments, the shape of the opening portion 53c and the coating material inclination surface R2 are elliptical in shape.

[0078] The distal end RI of the coating material R has an acute angle shape. The distal end RI is formed in the outer periphery of one side in the minor axis direction D2 of the coating material inclination surface R2 having the elliptical shape. That is, the distal end RI extends longer in the major axis direction D1, and is curved so as to rise smoothly from the center in the major axis direction D1 toward both sides in the major axis direction D1.

[0079] As described above, the coating material supply container 51 includes the coating material R and the distal tube 53 for holding the coating material R. The shape of the coating material R when viewed from the front side is a shape extending in the major axis direction D1 and the minor axis direction D2. The coating material R has an elliptical shape extending longer in the major axis direction D1. The distal end R1 has an acute angle shape, and extends in the major axis direction D1. Accordingly, the distal end R1 is applied to the coating target portion, and the coating material R is moved along the major axis direction D1. In this way, a thin line can be drawn finely on the coating target portion.

[0080] (Sixth group of embodiments) Next, a coating material supply container 61 will be described with reference to FIGS. 22A and 22B. An opening portion 63c of a distal tube 63 of the coating material supply container 61 has a hill-shaped projection 63e at the opposite side of a front end 63d. A projection 63e according to the third group of embodiments (FIGS. 19A and 19B) is disposed at the center in the major axis direction D1. In contrast, two projections 63e are disposed along the major axis direction D1.

[0081] The distal end of the projection 33e is pointed. In contrast, the distal end projections 63e and a valley portion 63f between the two projections 63e are curved. In addition, a valley portion 63g located at both sides in the major axis direction DI of the two projections 63e is also curved. A surface 63h at the front end 63d of the opening portion 63c extends along the major axis direction Dl, and is smoothly curved toward the outside of the opening portion 63c.

[0082] The coating material supply container 61 includes a solid coating material S. The coating material S has a distal end S1 having an acute angle shape extending along the major axis direction D1, and a coating material inclination surface S2 both inclining toward the axial direction and the minor axis direction D2. The distal end S1 extends along the surface 63h of the opening portion 63c on one side in the minor axis direction D2, and is smoothly curved outward from the coating material inclination surface S2. The coating material inclination surface S2 extends along a distal tube inclination surface 63b and the opening portion 63c of the distal tube 63.

[0083] As described above, the coating material supply container 61 includes the distal tube 63 and the coating material S. The shape of the coating material S when viewed from the front side is a shape extending in the major axis direction D1 and the minor axis direction D2. The coating material S has a ton extending longer in length in the major axis direction DL and the distal end S1 has an acute angle shape, and extends in the major axis direction D1. Thus, the distal end S1 is applied to the coating target portion, and the coating material S is moved along the major axis direction DL. In this way, a thin line can be drawn finely on the coating target portion.

[0084] (Seventh group of embodiments) Subsequently, a coating material supply container 71 will be described with reference to FIGS. 23A and 2313. In the coating material supply container 71, a shape of an opening portion 73c of a front end 73d of a distal tube 73 and a shape of a coating material T are distinguished from those according to the respective embodiments described above. The opening portion 73c has a plurality of hill-shaped projections 73f at the front end 73d.

[0085] The plurality of projections 73f are arranged side by side along the major axis direction D1. For example, the number of the projections 73f is three. A valley portion 73g is disposed between the plurality of projections 73f, and a valley portion 73h is disposed on both sides in the major axis direction D1 of the plurality of projections 73f. In this way, a valley-and-hills shape in which hills and valleys are arranged side by side along the major axis direction Dl, is formed at the front end 73d of the opening portion 73c.

[0086] The coating material T has a distal end T1 having an acute angle shape extending along the major axis direction D1 and a coating material inclination surface T2. The distal end T1 extends along the projection 73f and the valley portions 73g and 73h of the distal tube 73. That is, the distal end T1 has the valley-and-hill shape in which the hills and valleys are arranged side by side along the major axis direction D1. The coating material inclination surface T2 extends along the distal tube inclination surface 73b and the opening portion 73c of the distal tube 73. The ton of the coating material T when viewed from the front side is a shape extending in the major axis direction D1 and the minor axis direction D2. The coating material 1' has a shape extending longer in the major axis direction D1. The distal end T1 has an acute angle shape, and extends in the major axis direction D1.So a thin line can be drawn finely on the target portion of coating.

[0087] (Eighth group of embodiments) Next, a coating material supply container 81 will be described with reference to FIGS. 24A and 24B. A shape of an opening portion 83c of a distal tube 83 of the coating material supply container 81 and a shape of a coating material U are distinguished from those according to the respective embodiments described above. In the respective embodiments described above, the shape of the opening portion and the coating material when viewed from the front side is symmetrical to the center line passing through the center in the major axis direction DL. However, according to the present group of embodiments, the shape of the opening portion 83c and the coating material U when viewed from the front side is asymmetrical to a center line X passing through the center in the major axis direction DL. [0088j The shape of the opening portion 83c when viewed from the front side is a streamlined shape extending in the major axis direction D1. One side in the major axis direction D1, i.e., the opening portion 83e at a front end 83d of the distal tube 83 has a bent portion 83e which is bent into a U shape. On the other side in the major axis direction D1, the opening portion 83c has a pointed end portion 83f which is tapered.

[0089] The coating material U has a distal end U1 having an acute angle shape and a coating material inclination surface U2 both inclining toward the axial direction and toward the minor axis direction D2. The distal end LH extends along the opening portion 83c on one side in the minor axis direction D2. The surface coating material inclination surface U2 extends along the distal tube inclination surface 83b and the opening portion 83c of the distal tube 83. The shape of the coating material U when viewed from the front side is a shape extending in the major axis direction D1 and the minor axis direction D2. The coating material U has a shape extending longitudinally in the major axis direction D1. The distal end U1 has the acute angle shape and extends in the major axis direction D1. Accordingly, a thin line can be drawn finely by applying the distal end U1 to the coating target portion.

[0090] It will be appreciated that not all of the aspects, advantages, and features described herein might necessarily be realized by, or included in, any one exemplary embodiment or group of embodiments. Indeed, having described and illustrated various examples herein, it should be apparent that other examples could be varied in arrangement and detail. For example, in the first through eighth groups of embodiments, the distal tube and the coating material which have different shapes have been described. However, as long as the shape falls within the scope of the examples described above, the shape of the distal tube and the coating material may be further varied. For example, the shape of the coating material when viewed from the front side may be a rectangular shape including a long side extending in the major axis direction and a short side extending in the minor axis direction.The coating material could be diamond shaped or other polygonal shapes.

[0091] The coating material M having the coating material inclination surface M2 extending along the distal tube inclination surface 3b has been described. However, in an initial state before the coating material M is cut, the coating material M might not have a coating material inclination surface M2. That is, the coating material inclination surface M2 might not be formed immediately after the coating material M is manufactured or sold. The coating material inclination surface M2 could be formed by cutting the coating material M before being used. In this way, the time at which the coating material inclination surface is formed is not particularly limited.

[0092] The coating material supply container 1 including the container 2, the movable body 5, the female screw member 6, the spring member 7, the end cap 8, the intermediate tube 9, and the coating material supporting portion 11 has been described. However, the configuration of each portion of the coating material supply container is not limited to the components of the coating material supply container 1 described above, and can be suitably modified. An example has been described in which the intermediate tube 9 is attached to the distal tube 3. However, the tube intermediate tube 9 and the distal tube 3 could be integrally molded with each other.

[0093] An example has been described in which the ratchet mechanism 12 for enabling the feeding of the coating material M only by allowing the rotation of the distal tube 3 relative to the container main body 4 in only one direction, is disposed between the female screw member 6 and the spring member 7. However, instead of the ratchet mechanism 12, a ratchet mechanism for enabling the coating material M to be discharged and stored may be provided. That is, the ratchet mechanism may be provided which can prevent the coating material M from being fed excessively, by producing a clicking sound and a resisting force (clicking sensation) in response to the relative rotation between the distal tube 3 and the container main body 4.

[0094] The coating material supply container 1 has been described which includes the supply mechanism including the distal tube 3, the container main body 4, the movable body 5, the female screw member 6, the spring member 7, the tip cap 8, and the intermediate tube 9, i.e., a rotary type supply mechanism using the screw portion 10. However, the supply mechanism of the coating material supply container may be suitably modified. For example, the mechanism may be configured similarly to a supply mechanism found in a retractable ballpoint pen or other writing instrument.

[0095] An example has been described in which the coating material M is an eyebrow pencil and the coating material supply container 1 is an eyebrow makeup supply container. However, for example, the coating material supply container is also applicable to various stick-shaped cosmetic materials such as eyeliners, correction pencils, or lip liners. Furthermore, the coating material supply container is also applicable to writing instruments, design pencils, and drawing materials. Accordingly, the coating target portion may include an eyelid, an eyebrow, a cheek, a lip, other parts of the face, body, or skin, or any combination thereof. In addition, the coating target portion may include paper, canvas, ceramics, or other media and objects on which a coating can be written, drawn, or coated.All modifications and variations within the spirit and scope of the subject matter claimed herein are claimed.
