[0003] Patent Document 1: Japanese Patent Application Publication No. 2021-151379 Summary of the invention

[0004] In the above-mentioned coating container, the coating material is held by the first coating material holding portion and the second coating material holding portion provided at the front end portion of the front barrel. However, there are portions other than the front end portion of the front barrel where the coating material is not held. In the case where the coating material is flat, if there are many portions where the coating material is not held as described above, there is a concern that the coating material may be deformed or damaged. In particular, when the flat coating material is loaded into the coating container, when the flat coating material is delivered, or when the coating container is carried, the coating material may be deformed or damaged.

[0005] An object of the present invention is to provide a coating container capable of suppressing deformation and breakage of a flat coating material.

[0006] (1) A coating container according to one embodiment of the present invention is a coating container for delivering a coating material. The coating container includes a tubular component and a delivery mechanism, wherein the tubular component has a tubular hole for storing the coating material and an opening through which the coating material is exposed, and the delivery mechanism advances the coating material stored in the tubular hole and causes the coating material to protrude from the opening. The shape of the tubular hole of the tubular component observed along the axial direction in which the axis of the tubular component extends, and the shape of the coating material observed along the axial direction are set to be a flat shape having a major axis and a minor axis. The coating material has a thickness in the minor axis direction in which the minor axis extends. The coating material has a flat surface extending in the major axis direction in which the major axis extends, and in the axial direction. The tubular component has a retaining portion that retains the coating material by contacting the flat surface. The retaining portion extends from one end side of the flat surface in the axial direction across the other end side in a state of contacting the flat surface.

[0007] The coating container is provided with a tubular component for storing coating material and a delivery mechanism for delivering the coating material stored in the tubular component, and the delivery mechanism delivers the coating material so that the coating material protrudes from the tubular component. The shape of the barrel hole of the tubular component observed along the axial direction and the shape of the coating material observed along the axial direction are set to a flat shape with a major axis and a minor axis. The coating material has a flat surface extending in the axial direction and the major axis direction, and the tubular component has a retaining portion for holding the coating material by contacting the flat surface. The retaining portion contacting the flat surface of the coating material extends from one end side in the axial direction of the flat surface across the other end side. Therefore, by extending the retaining portion from one side in the axial direction of the flat surface across the other side in a state of contacting the flat surface, the retaining portion can hold the coating material in a wide range from one side in the axial direction to the other side. Therefore, even when holding a flat coating material, deformation and breakage of the coating material can be suppressed by holding the coating material in a range extending from one side to the other side in the axial direction of the flat surface.

[0008] (2) The coating container involved in other embodiments of the present invention is a coating container for delivering a coating material. The coating container includes a tubular component and a delivery mechanism, wherein the tubular component has a tubular hole for storing the coating material and an opening through which the coating material is exposed, and the delivery mechanism advances the coating material stored in the tubular hole and causes the coating material to protrude from the opening. The shape of the tubular hole of the tubular component observed along the axial direction as the direction in which the axis of the tubular component extends, and the shape of the coating material observed along the axial direction are set to be a flat shape having a major axis and a minor axis. The coating material has a thickness in the minor axis direction as the direction in which the minor axis extends. The coating material has a flat surface extending in the major axis direction as the direction in which the major axis extends, and in the axial direction. The tubular component has a retaining portion that retains the coating material by contacting the flat surface. The retaining portion is a leaf spring portion divided by a slit formed in the tubular component. The leaf spring portion contacts the coating material and is elastically deformed in the thickness direction of the tubular component.

[0009] In this coating container, the shape of the barrel hole of the tubular component observed along the axial direction and the shape of the coating material observed along the axial direction are set to a flat shape with a major axis and a minor axis, and the coating material has a flat surface extending in the axial direction and the major axis direction. The tubular component has a retaining portion that holds the coating material by contacting with the flat surface, and the retaining portion is a leaf spring portion divided by a slit formed in the tubular component. The leaf spring portion is in contact with the coating material and elastically deforms along the thickness direction of the tubular component. Therefore, by contacting the elastically deformed leaf spring portion with the flat surface, the coating material can be held in a wide range. Therefore, even when holding a coating material in a flat shape, by making the leaf spring portion contact with the flat surface and holding the coating material, the coating material can be held with a moderate holding force, and the deformation and breakage of the coating material can be suppressed.

[0010] (3) In the above (1), the retaining portion may also be in the shape of a protrusion protruding toward the flat surface. The tubular member may also have a plurality of retaining portions arranged along the major axis direction and along the minor axis direction. The coating material may also be sandwiched between the plurality of retaining portions arranged along the minor axis direction. In this case, since the coating material is held in a state sandwiched between a pair of retaining portions arranged along the minor axis direction, the coating material can be more securely held by the plurality of retaining portions. As a result, deformation and breakage of the coating material can be more reliably suppressed.

[0011] (4) In any of the above (1) to (3), the tubular member may include a first structural member and a second structural member joined to the first structural member. In this case, the coating material can be held between the first structural member and the second structural member. Therefore, by joining the second structural member to the first structural member in a state where the coating material is located between the first structural member and the second structural member, the coating material can be easily loaded onto the tubular member.

[0012] (5) In the above (4), the first structural member and the second structural member may be joined to each other in a direction perpendicular to the axial direction. In this case, since the coating material can be held between the first structural member and the second structural member that are opposed to each other in a direction perpendicular to the axial direction, the coating material can be easily loaded and held.

[0013] (6) In the above (4), the first structural member and the second structural member may be joined to each other along the axial direction. In this case, since the first structural member is joined to the second structural member along the axial direction, the first structural member can be easily joined to the second structural member.

[0014] (7) In any of the above (1) to (6), the coating container may also include a front cylinder, a rear cylinder, a threaded cylinder, and a moving body, wherein the front cylinder accommodates the cylindrical component and has a first internal thread inside, the rear cylinder is connected to the front cylinder so as to be relatively rotatable, the threaded cylinder is provided inside the rear cylinder and has a first external thread that is screwed with the first internal thread, and a second internal thread formed on the inner surface, the moving body moves forward inside the threaded cylinder and has a second external thread that is screwed with the second internal thread. The delivery mechanism may also include a first screwing portion and a second screwing portion, wherein the first screwing portion moves the threaded cylinder forward relative to the front cylinder through the screwing action of the first internal thread and the first external thread when the threaded cylinder rotates relative to the front cylinder, and the second screwing portion moves the moving body forward relative to the threaded cylinder through the screwing action of the second internal thread and the second external thread when the rear cylinder rotates relative to the threaded cylinder. When the rear cylinder rotates relative to the front cylinder in one direction, the threaded cylinder can rotate synchronously with the rear cylinder and the threaded cylinder advances to the forward limit relative to the rear cylinder, thereby causing the tubular component and the coating material to protrude forward from the front cylinder. When the rear cylinder rotates relative to the front cylinder in one direction under the state that the threaded cylinder reaches the forward limit, the rear cylinder can rotate relative to the threaded cylinder and the moving body advances relative to the threaded cylinder, thereby sending out the coating material relative to the tubular component. In this case, since the coating material can be advanced together with the tubular component by causing the rear cylinder to rotate relative to the front cylinder in one direction, the deformation and damage of the coating material when sending out the coating material can be suppressed. In addition, when the threaded cylinder reaches the forward limit and the tubular component and the coating material protrude forward from the front cylinder, the coating material is sent out relative to the tubular component for the first time. Therefore, the amount of coating material sent out relative to the tubular component can be reduced, thereby more reliably suppressing the damage of the coating material when applying.

[0015] According to the present invention, deformation and breakage of a flat coating material can be suppressed. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Below, while referring to the attached Figure 1 The embodiment of the coating container involved in the present invention is described. In the description of the drawings, the same symbols are marked for the same or equivalent elements, and repeated descriptions are appropriately omitted. In the drawings, for the convenience of understanding, a part is sometimes simplified or exaggerated, and the dimensional ratio is not limited to the content recorded in the drawings.

[0018] In the present invention, "coating material" refers to a substance that is coated on a coated portion as a coating object. "Coating material" is, for example, a cosmetic or a painting material. In this embodiment, an example in which the coating material is a cosmetic is described. "Cosmetic material" is, for example, an eyebrow pencil, an eyeliner, a lipstick, a lip liner, a lip gloss, a beauty stick, or a concealer.

[0019] Figure 1 (a) is a perspective view showing a coating container 1 according to the embodiment. Figure 1 (b) is a perspective view showing a state where the coating material M is delivered from the coating container 1. Figure 1 (a) and Figure 1 As shown in (b), the coating container 1 includes a front tube 2, a rear tube 3 connected to the front tube 2, and a cover 4 connected to the rear tube 3.

[0020] The coating container 1 includes a front tube 2, a rear tube 3, and a cover 4, and some parts are provided in a cylindrical shape. In the coating container 1, when the parts are assembled, the directions in which the axes L of the multiple cylindrical parts extend are consistent. Hereinafter, the direction in which the axis L extends is referred to as the axis direction D1. For example, the axis direction D1 is consistent with the length direction of the coating container 1.

[0021] "Front", "front side" and "front" indicate the direction from the rear tube 3 toward the front tube 2 in the axial direction D1, and "rear", "rear side" and "rear" indicate the direction from the front tube 2 toward the rear tube 3 in the axial direction D1. "Radial" indicates the direction orthogonal to the axis L. "Radial outer side" indicates the direction away from the axis in the radial direction, and "radial inner side" indicates the direction close to the axis in the radial direction. "Direction of rotation" indicates the direction along the ring centered on the axis L (circumferential direction). In the present embodiment, the delivery direction in which the coating material M is delivered is the front (advancing direction), and the opposite direction is the rear.

[0022] The coating container 1 is in the shape of a rod extending in the axial direction D1. The coating container 1 delivers the coating material M. For example, the coating container 1 is a pen-shaped container that delivers (pushes out) the coating material M contained in the coating container 1. The coating material M is formed into a flat shape and is solid. The coating material M is, for example, a plate-shaped cosmetic material. However, the coating material M may also be a plate-shaped painting material. As an example, the coating material M may be an eyebrow cream, in which case the coating container 1 is an eyebrow cream coating container.

[0023] The coating container 1 includes a tubular member 10 having an opening 10 b through which the coating material M is exposed. The rear tube 3 is connected to the front tube 2 so as to be relatively rotatable. Figure 2 (a) Figure 2 (b) and Figure 2 (c) is a perspective view showing the front tube 2, the tubular member 10 and the coating material M. Figure 3 It is a cross-sectional view showing the coating container 1.

[0024] like Figure 1 (a) Figure 1 (b) Figure 2 (a) Figure 2 (b) Figure 2 (c) and Figure 3 As shown, the front cylinder 2 has a front end opening 2b that allows the cylindrical member 10 and the coating material M to protrude forward. The cylindrical member 10 has a cylindrical hole 10c for storing the coating material M. The cylindrical hole 10c extends backward from the opening 10b. The coating container 1 has a delivery mechanism 15 that allows the coating material M stored in the cylindrical hole 10c to move forward and protrude from the opening 10b.

[0025] like Figure 1 (a) Figure 1 (b) and Figure 2 As shown in (a), if the rear cylinder 3 is rotated relative to the front cylinder 2 in one direction (for example, clockwise) by the delivery mechanism 15, the tubular member 10 and the coating material M protrude forward from the front end opening 2b of the front cylinder 2. Figure 2 (a) and Figure 2 As shown in (b), when the rear tube 3 is further rotated in one direction relative to the front tube 2 while the tubular member 10 and the coating material M protrude a certain amount from the front end opening 2b, the coating material M is delivered forward relative to the tubular member 10.

[0026] like Figure 2 (b) and Figure 2 As shown in (c), by the delivery mechanism 15, if the rear cylinder 3 is relatively rotated in the opposite direction to the above-mentioned one direction (for example, counterclockwise) relative to the front cylinder 2, the tubular member 10 and the coating material M are both sunk to the rear relative to the front end opening 2b of the front cylinder 2. By the delivery mechanism 15, the coating material M advances relative to the tubular member 10, retreats together with the tubular member 10, and does not retreat relative to the tubular member 10. The delivery mechanism 15 will be described in detail later.

[0027] like Figure 3 As shown, the coating container 1 has a threaded barrel 5 provided inside the rear barrel 3, a moving body 6 moving inside the threaded barrel 5, a pressing member 7 located between the moving body 6 and the coating material M, a tail plug 8 sealing the end of the rear side of the rear barrel 3, and a coating tool 9 fixed to the tail plug 8. For example, the tail plug 8 is inserted with the coating tool 9 and holds the inserted coating tool 9. As an example, the coating tool 9 is a spiral brush, and the tail plug 8 functions as a brush holder.

[0028] The cover 4 is mounted on the tail plug 8 in a manner covering the coating tool 9, and is configured to be removable relative to the tail plug 8. It should be noted that the structure of the cover 4, the tail plug 8, and the coating tool 9 is not limited to the above example, and can be appropriately changed. In addition, the coating container 1 can also be a container without the coating tool 9 and the cover 4. The threaded barrel 5, the movable body 6, and the pushing member 7 will be described in detail later.

[0029] Figure 4 FIG. 2 is a diagram showing the front tube 2, the tubular member 10 and the coating material M as viewed from the front. Figure 3 as well as Figure 4As shown, the shape of the opening 10b observed along the axial direction D1 is set to a flat shape having a major axis and a minor axis. The shape of the cylindrical hole 10c observed along the axial direction D1 is set to a flat shape having a major axis L11 and a minor axis L12, and the shape of the coating material M observed along the axial direction D1 is set to a flat shape having a major axis L21 and a minor axis L22.

[0030] For example, the major axis L21 and the minor axis L22 of the coating material M are respectively consistent with the major axis L11 and the minor axis L12 of the barrel hole 10c. In the present embodiment, the "flat shape" means a shape in which the length in the major axis direction D2, which is the direction in which the major axis L11 (major axis L21) extends, is longer than the length in the minor axis direction D3, which is the direction in which the minor axis L12 (minor axis L22) extends. The front barrel 2 has a front end 2j. The front end 2j is one end in the axial direction D of the front barrel 2, and is located at one end in the major axis direction D2 of the front barrel 2.

[0031] For example, when viewed from the front, the front tube 2 is circular. The cross-sectional shape of the front tube 2 orthogonal to the axial direction D1 transitions from a circular shape to a flat shape as it moves from the rear tube 3 toward the front end opening 2b. The front tube 2 has a front end portion 2d formed with the front end opening 2b, and a tapered surface 2f extending from the front end portion 2d toward the rear tube 3. In the tapered surface 2f, the length of the front tube 2 in the major axis direction D2 and the length of the front tube 2 in the minor axis direction D3 become longer as they approach the rear tube 3.

[0032] When viewed along the axial direction D1, the front end opening 2b is flat (for example, a rounded rectangle). The front end portion 2d has a smooth surface 2g formed with the front end opening 2b, and a curved surface 2h extending from the smooth surface 2g to the tapered surface 2f. When viewed along the short axis direction D3, the smooth surface 2g is curved in a manner that bulges toward the outside of the front tube 2 as it moves away from the front end 2j.

[0033] The smooth surface 2g has an asymmetric shape with respect to a reference line A that passes through the center 2x of the front tube 2 when viewed along the axial direction D1 and extends along the short axis direction D3. More specifically, the smooth surface 2g has a protruding area 2g1 that protrudes to one side of the long axis direction D2. As an example, the protruding area 2g1 is a trapezoidal shape having an upper base extending along the short axis direction D3. When viewed along the axial direction D1, the curved surface 2h is a rounded rectangle surrounding the smooth surface 2g. The curved surface 2h is curved in a manner that bulges toward the outside of the front tube 2.

[0034] The front tube 2 has an inner surface 2k extending rearward from the front end opening 2b. The inner surface 2k includes a first inner surface 2k1 extending in the axial direction D1 and the long axis direction D2, and a second inner surface 2k2 extending in the axial direction D1 and the short axis direction D3. The inner surface 2k includes a pair of first inner surfaces 2k1 arranged along the short axis direction D3, and a pair of second inner surfaces 2k2 arranged along the long axis direction D2.

[0035] The coating material M has a thickness in the short-axis direction D3. The coating material M has a flat surface M1 extending in the axial direction D1 and the long-axis direction D2, a side surface M2 extending in the axial direction D1 and the short-axis direction D3, and a front end surface M3 located at the end of the front side of the coating material M. The coating material M has a pair of flat surfaces M1 arranged along the short-axis direction D3, and a pair of side surfaces M2 arranged along the long-axis direction D2. The flat surface M1 and the side surface M2 are, for example, flat.

[0036] For example, the front end surface M3 is inclined relative to both the axial direction D1 and the long axis direction D2. The front end surface M3 is inclined along the front end portion 2d (smooth surface 2g) of the front tube 2. The coating material M has a front end portion M4. The front end portion M4 is one end of the coating material M in the axial direction D1 and is located at one end of the coating material M in the long axis direction D2. The front end surface M3 extends obliquely rearward from the front end portion M4.

[0037] The tubular member 10 is located inside the front end opening 2b of the front barrel 2. For example, the tubular member 10 contacts a portion of the inner surface 2k (the second inner surface 2k2). When viewed along the axial direction D1, the tubular member 10 is flat. As an example, when viewed along the axial direction D1, the tubular member 10 is a rounded rectangular shape. The tubular member 10 has a retaining portion 11 that retains the coating material M in the barrel hole 10c.

[0038] The retaining portion 11 is in the shape of a protrusion protruding from the inner peripheral surface 10d of the cylindrical member 10 that defines the cylindrical hole 10c. When viewed along the axial direction D1, the retaining portion 11 is triangular. A portion (e.g., the top) of the retaining portion 11 may also bite into the flat surface M1 of the coating material M. In this way, the retaining portion 11 retains the coating material M by contacting with the coating material M.

[0039] For example, the tubular member 10 has a plurality of retaining portions 11. The plurality of retaining portions 11 are arranged along the long axis direction D2. For example, one of a pair of retaining portions 11 arranged along the long axis direction D2 is arranged on one side as viewed from the reference line A, and the other of a pair of retaining portions 11 arranged along the long axis direction D2 is arranged on the other side as viewed from the reference line A. The pair of retaining portions 11 arranged along the long axis direction D2 may also be arranged at positions symmetrical to each other with respect to the reference line A.

[0040] A plurality of retaining portions 11 are arranged along the minor axis direction D3. Thus, the coating material M is sandwiched between a pair of retaining portions 11 arranged along the minor axis direction D3. By configuring the retaining portions 11 in the above manner, the coating material M can be firmly held in the barrel hole 10c of the tubular member 10. However, the shape, number and configuration of the retaining portions 11 can be appropriately changed. It should be noted that the tubular member 10 will be described in detail later.

[0041] Figure 5 (a) is a cross-sectional view of the front tube 2 when cut along a plane extending along the axial direction D1 and the short-axis direction D3. Figure 5 (b) is a cross-sectional view of the front tube 2 when cut along a plane extending along the axial direction D1 and the long axis direction D2. Figure 3 , Figure 5 (a) and Figure 5 As shown in (b), the front tube 2 has a recessed portion 2p formed as an inner surface 2k. The recessed portion 2p includes a first recessed portion 2p1 recessed in the major axis direction D2 and a second recessed portion 2p2 recessed in the minor axis direction D3.

[0042] The recessed portion 2p includes a pair of first recessed portions 2p1 arranged along the major axis direction D2, and a pair of second recessed portions 2p2 arranged along the minor axis direction D3. In a cross section orthogonal to the axial direction D1, the recessed portion 2p is cross-shaped. The tubular member 10 is engaged with the recessed portion 2p in the rotational direction. Thus, the tubular member 10 is engaged with the front barrel 2 in a manner that can rotate synchronously with the front barrel 2.

[0043] The front tube 2 has a tube portion 2q extending in the axial direction D1 behind the tapered surface 2f. For example, the tube portion 2q is cylindrical. The diameter of the tube portion 2q decreases from the step portion 2r located at the rear end of the tapered surface 2f. The tube portion 2q has a convex portion 2s that protrudes radially outward from the front tube 2 and engages with the inner surface 3b of the rear tube 3 in the axial direction.

[0044] By engaging the convex portion 2s with the inner surface 3b, the front barrel 2 is engaged with the rear barrel 3 in a manner that it cannot move in the axial direction and can rotate relatively. The barrel portion 2q has a through hole 2t that penetrates the front barrel 2 in the radial direction. For example, when viewed from the radial outer side of the front barrel 2, the through hole 2t is rectangular. The barrel portion 2q has, for example, a pair of through holes 2t, and the pair of through holes 2t are arranged in the radial direction of the front barrel 2.

[0045] The front barrel 2 has a first internal thread 2v inside the front barrel 2. The first internal thread 2v is, for example, a protrusion that protrudes from the inner surface 2k and extends in a direction inclined relative to the rotation direction. For example, the first internal thread 2v is located at the end of the rear side of the through hole 2t. The front barrel 2 has, for example, a plurality of first internal threads 2v, and the plurality of first internal threads 2v are arranged in the radial direction of the front barrel 2.

[0046] Figure 6(a) is a side view showing the threaded barrel 5. Figure 6 (b) is a three-dimensional view showing the threaded barrel 5. Figure 3 , Figure 6 (a) and Figure 6 As shown in (b), the threaded barrel 5 is provided inside the rear barrel 3. The threaded barrel 5 has a first barrel portion 5c formed with a first external thread 5b screwed into the first internal thread 2v of the front barrel 2, a second barrel portion 5d located rearward of the first barrel portion 5c, and a flange portion 5f located between the first barrel portion 5c and the second barrel portion 5d.

[0047] The first external thread 5b is spirally formed on the outer peripheral surface of the first barrel portion 5c. The first external thread 5b is screwed with the first internal thread 2v of the front barrel 2, so that when the threaded barrel 5 rotates relative to the front barrel 2, the threaded barrel 5 moves only a certain distance along the axial direction D1 relative to the front barrel 2. The flange portion 5f is arranged between the rear end 2w of the front barrel 2 and the protruding portion 3c of the rear barrel 3 described below.

[0048] The delivery mechanism 15 has a first screwing portion 16, and when the threaded barrel 5 rotates relative to the front barrel 2, the first screwing portion 16 advances the threaded barrel 5 relative to the front barrel 2 through the screwing action of the first internal thread 2v and the first external thread 5b. The first screwing portion 16 includes the first internal thread 2v and the first external thread 5b. The threaded barrel 5 is configured to be able to advance from the position where the flange portion 5f contacts the protrusion 3c to the position where the flange portion 5f contacts the rear end 2w of the front barrel 2. The position of the threaded barrel 5 where the flange portion 5f contacts the protrusion 3c is the retreat limit of the threaded barrel 5, and the position of the threaded barrel 5 where the flange portion 5f contacts the rear end 2w is the advancement limit of the threaded barrel 5.

[0049] The threaded barrel 5, for example, accommodates a portion of the cylindrical member 10 (as an example, the rear end). The first cylindrical portion 5c has a cylindrical portion 5g located in front of the first external thread 5b. The cylindrical portion 5g is, for example, cylindrical. For example, the cylindrical portion 5g has a window portion 5h that penetrates the cylindrical portion 5g in the radial direction of the threaded barrel 5. The cylindrical member 10 is engaged with the window portion 5h in the axial direction D1. As a result, the cylindrical member 10 is immovable in the axial direction and is relatively rotatable and engaged with the threaded barrel 5.

[0050] The second barrel portion 5d has a slit 5j and a spring portion 5k divided by the slit 5j. The slit 5j includes a pair of first slits 5j1 extending in the rotation direction D4, and a second slit 5j2 connecting the pair of first slits 5j1 to each other. The pair of first slits 5j1 are arranged along the axial direction D1. The second slit 5j2 extends along the axial direction D1 between the ends of the pair of first slits 5j1 in the rotation direction D4. The spring portion 5k divided by the pair of first slits 5j1 and the second slit 5j2 has elasticity in the radial direction of the threaded barrel 5.

[0051] The spring portion 5k has a convex portion 5p protruding radially outward of the threaded barrel 5. The convex portion 5p has a first inclined surface 5p1 extending obliquely radially outward from the outer surface 5q of the threaded barrel 5, a second inclined surface 5p2 extending obliquely radially outward from the end of the first inclined surface 5p1 opposite to the outer surface 5q, a top surface 5p3, and a wall surface 5p4 extending radially inward from the top surface 5p3 of the threaded barrel 5. The spring portion 5k is configured to be elastically deformable in the radial direction of the threaded barrel 5 when the convex portion 5p abuts against the protruding portion 3c of the rear barrel 3.

[0052] The threaded barrel 5 has a second internal thread 5r formed on the inner surface of the threaded barrel 5. The second internal thread 5r extends spirally from the rear end 5t of the second barrel portion 5d, for example. The threaded barrel 5 has, for example, a pair of second internal threads 5r, which are opposite to each other in the radial direction of the threaded barrel 5. The area between the pair of second internal threads 5r in the threaded barrel 5 is set as a holding portion for holding the movable body 6. A slit 5s is formed between the pair of second internal threads 5r. The slit 5s makes it easy to demold the threaded barrel 5 from the mold when it is manufactured by resin molding.

[0053] As described above, the second barrel portion 5d has the slit 5s between the pair of second internal threads 5r. The slit 5s extends forward from the rear end 5t of the threaded barrel 5. The second barrel portion 5d has, for example, a pair of slits 5s that face each other in the radial direction of the threaded barrel 5.

[0054] Figure 7 2 is a cross-sectional view of the rear tube 3 when cut along a plane extending in the radial direction and the axial direction D1 of the rear tube 3. Figure 3 as well as Figure 7 As shown in FIG. 1 , the rear tube 3 is cylindrical with a smooth outer surface 3d. The rear tube 3 has an annular convex portion 3f protruding radially inward on the inner surface 3b, and an annular concave portion 3g located behind the annular convex portion 3f and recessed radially outward on the inner surface 3b. The convex portion 2s of the front tube 2 that passes over the annular convex portion 3f to the rear is fitted into the annular concave portion 3g.

[0055] For example, the rear tube 3 has a plurality of protrusions 3c on the inner surface 3b. The plurality of protrusions 3c are arranged in the circumferential direction of the rear tube 3. For example, the protrusion 3c is in the shape of a plate extending in the axial direction D1 and having a thickness in the circumferential direction of the rear tube 3. The protrusion 3c has a first portion 3c1 protruding radially inward of the rear tube 3 in the inner surface 3b, and a second portion 3c2 protruding radially inward further than the first portion 3c1 behind the first portion 3c1. The protrusion 3c also has an inclined portion 3c3 extending obliquely from the rear end of the second portion 3c2 in a manner that expands the diameter radially outward.

[0056] The convex portion 5p of the threaded barrel 5 (see Figure 6(b)) engages with the protrusion 3c in the rotation direction. The threaded barrel 5 is configured to be rotatable in only one direction relative to the rear barrel 3. More specifically, the threaded barrel 5 is configured to be in one direction (in which the first inclined surface 5p1 of the convex portion 5p contacts the protrusion 3c) in which the first inclined surface 5p1 of the convex portion 5p contacts the protrusion 3c. Figure 6 (b) is counterclockwise) and is rotatable relative to the rear tube 3.

[0057] On the other hand, the threaded barrel 5 is in the opposite direction (in the direction opposite to the direction in which the wall surface 5p4 of the convex portion 5p contacts the protruding portion 3c) Figure 6 In other words, when the threaded barrel 5 is intended to rotate in the opposite direction relative to the rear barrel 3, the wall surface 5p4 abuts against the protruding portion 3c, and thus the rotation is restricted.

[0058] The rear tube 3 has a knurled portion 3h located behind the protruding portion 3c, an annular recessed portion 3j located behind the knurled portion 3h, and an annular convex portion 3k located behind the annular recessed portion 3j. The tail plug 8 is engaged with the knurled portion 3h, the annular recessed portion 3j, and the annular convex portion 3k. By engaging the tail plug 8 with the knurled portion 3h, the annular recessed portion 3j, and the annular convex portion 3k, the tail plug 8 is engaged with the rear tube 3 in a manner that it cannot move in the axial direction and can rotate synchronously.

[0059] The tail plug 8 has a first holding portion 8b for holding the movable body 6, an engaging portion 8c engaged with the knurled portion 3h, the annular recessed portion 3j and the annular protruding portion 3k of the rear tube 3, a flange portion 8d exposed to the outside of the coating container 1, and a second holding portion 8f for holding the coating tool 9. The coating tool 9 protrudes rearward from the second holding portion 8f.

[0060] The second holding portion 8f includes an outer cylinder portion 8h engaged with the cover portion 4, an inner cylinder portion 8j located radially inward of the outer cylinder portion 8h, and a plurality of ribs 8k located between the outer cylinder portion 8h and the inner cylinder portion 8j. The inner cylinder portion 8j includes a hole portion 8g into which the coating tool 9 is inserted. The second holding portion 8f holds the coating tool 9 by inserting the coating tool 9 into the hole portion 8g. The flange portion 8d is located between the engaging portion 8c and the second holding portion 8f.

[0061] The engaging portion 8c is, for example, cylindrical. The engaging portion 8c has an annular convex portion 8p engaged with the annular concave portion 3j of the rear tube 3 in the axial direction D1, and a convex portion 8q engaged with the knurled portion 3h of the rear tube 3 in the rotational direction. The first retaining portion 8b is rod-shaped. The first retaining portion 8b protrudes forward from the engaging portion 8c. For example, the moving body 6 is cylindrical, and the first retaining portion 8b is inserted into the moving body 6.

[0062] Figure 8 (a) is a side view showing the moving body 6. Figure 8 (b) Figure 8 (a) AA line cross-sectional view. Figure 3 , Figure 8 (a) and Figure 8 As shown in (b), the movable body 6 has a second external thread 6b that is screwed with the second internal thread 5r of the threaded barrel 5. The delivery mechanism 15 has a second screwing portion 17, and the second screwing portion 17 advances the movable body 6 relative to the threaded barrel 5 through the screwing action of the second internal thread 5r and the second external thread 6b. The second screwing portion 17 includes the second internal thread 5r and the second external thread 6b.

[0063] The movable body 6 has a recessed portion 6f which is recessed radially outward in the inner surface 6d and extends in the axial direction D1. The movable body 6 has a plurality of recessed portions 6f, which are arranged in the circumferential direction. The first retaining portion 8b of the tail plug 8 engages with the recessed portion 6f in the rotational direction. By engaging the first retaining portion 8b with the recessed portion 6f in the rotational direction, the tail plug 8 engages with the movable body 6 in a manner that allows synchronous rotation. For example, the movable body 6 has a window portion 6g which penetrates the movable body 6 in the radial direction. The movable body 6 has a pair of window portions 6g, which are arranged in the radial direction of the movable body 6. The first retaining portion 8b located inside the movable body 6 can be visually confirmed through the window portion 6g.

[0064] The movable body 6 has a connecting portion 6c connected to the pushing member 7 in front of the second external thread 6b. The connecting portion 6c is, for example, cylindrical. The connecting portion 6c has a hole portion 6k that is recessed backward from the front end 6j of the movable body 6, and a through hole 6h that penetrates the connecting portion 6c in the radial direction. The connecting portion 6c has a pair of through holes 6h, and the pair of through holes 6h are arranged in the radial direction. The hole portion 6k is connected to the through hole 6h, and the pushing member 7 is engaged with the hole portion 6k and the through hole 6h. By engaging the pushing member 7 with the hole portion 6k and the through hole 6h, the movable body 6 cannot move in the axial direction relative to the pushing member 7 and can be relatively rotatably engaged.

[0065] Fig. 9 (a) is a side view showing the pressing member 7. Fig. 9 (b) is a perspective view showing the pressing member 7. Fig.10 FIG. 2 is an enlarged perspective view of the rear end portion 7b of the pushing member 7. Figure 8 (b) Fig. 9 (a) Fig. 9 (b) and Fig.10 As shown, the rear end portion 7b of the pressing member 7 is a portion that engages with the moving body 6 and is, for example, in the shape of a stepped cylinder.

[0066] The rear end portion 7b has a cylindrical outer surface 7c and an annular convex portion 7d protruding from the outer surface 7c. The annular convex portion 7d has a top surface 7f extending in the circumferential direction and an inclined surface 7g extending backward and obliquely downward relative to the top surface 7f. The connecting portion 6c of the moving body 6 has an inner surface 6p that divides the hole portion 6k.

[0067] The inner surface 6p has an inclined surface 6q extending obliquely radially inward as it moves away from the front end 6j, and a top surface 6r extending rearward from the end of the inclined surface 6q opposite to the front end 6j. When the rear end 7b of the pressing member 7 is inserted into the hole 6k, the annular protrusion 7d passes over the inner surface 6p rearward and engages with the through hole 6h in the axial direction D1.

[0068] like Figure 3 , Fig. 9 (a) Fig. 9 (b) and Fig.10 As shown, the pressing member 7 includes a rotation stopper 7h that functions as a rotation stopper for the tubular member 10 and a push-out portion 7j that is located in front of the rotation stopper 7h and pushes out the coating material M. The rotation stopper 7h extends in the axial direction D1 inside the threaded barrel 5 .

[0069] The pressing member 7 includes a first plate portion 7k extending in the axial direction D1 and the long axis direction D2 and having thickness in the short axis direction D3, and a second plate portion 7p intersecting the first plate portion 7k. The second plate portion 7p extends in the axial direction D1 and the short axis direction D3 and has thickness in the long axis direction D2.

[0070] The pressing member 7 has a pair of second plate-like portions 7p, which are arranged along the short axis direction D3. Each second plate-like portion 7p protrudes upward and downward relative to the center of the first plate-like portion 7k in the long axis direction D2. Therefore, when viewed from the front, the pressing member 7 is in a cross shape.

[0071] For example, the portion of the pushing member 7 where the first plate-shaped portion 7k and the second plate-shaped portion 7p are provided is the anti-rotation portion 7h, and the portion of the pushing member 7 where only the first plate-shaped portion 7k is provided is the push-out portion 7j. The anti-rotation portion 7h engages with the tubular member 10 in the rotation direction inside the threaded barrel 5. Thus, the rotation of the pushing member 7 relative to the tubular member 10 is prevented.

[0072] For example, the length of the push-out portion 7j in the axial direction D1 is shorter than the length of the anti-rotation portion 7h in the axial direction D1. The push-out portion 7j is located in front of the anti-rotation portion 7h. The push-out portion 7j has a front end surface 7q that abuts against the coating material M. For example, the shape and size of the front end surface 7q are the same as the shape and size of the rear end surface M5 of the coating material M. The front end surface 7q and the rear end surface M5 are each set to a flat shape having a long axis extending in the long axis direction D2 and a short axis extending in the short axis direction D3.

[0073] Next, the tubular member 10 will be described in more detail. Fig.11 (a) is a perspective view showing the tubular member 10. Fig.11(b) is a cross-sectional perspective view showing the tubular member 10 cut along a plane extending in the axial direction D1 and the long axis direction D2. Fig.11 (a) and Fig.11 As shown in FIG. 5( b ), the tubular member 10 includes a connection portion 12 to which the threaded barrel 5 is connected, a retaining barrel portion 13 to retain the coating material M, and a flange portion 14 located between the connection portion 12 and the retaining barrel portion 13 .

[0074] The shape of the retaining cylinder 13 when viewed along the axial direction D1 is a flat shape having a major axis extending along the major axis direction D2 and a minor axis extending along the minor axis direction D3. As described above, the tubular member 10 has the retaining portion 11 that retains the coating material M. In the retaining portion 11, the coating material M extends along the axial direction D1.

[0075] like Figure 4 as well as Fig.11 As shown in (b), the retaining portion 11 extends from one end side in the axial direction D1 of the flat surface M1 to the other end side while in contact with the flat surface M1 of the coating material M. "The retaining portion extends from one end side in the axial direction of the flat surface to the other end side" means that the retaining portion extends from one end side in the axial direction of the flat surface toward the other end side.

[0076] “The holding portion extends from one end side in the axial direction of the flat surface to the other end side” may also mean that the holding portion extends linearly from one end side in the axial direction of the flat surface toward the other end. In this embodiment, by extending the holding portion 11 from one end side in the axial direction D1 of the flat surface M1 to the other end side, even a coating material M with a shorter length (thinner) in the short axis direction D3 can be firmly held.

[0077] In the tubular member 10 of the present embodiment, the holding portion 11 is formed in the cylindrical hole 10c, so that even the coating material M having a length of 1 mm or less in the short axis direction D3 can be firmly held. For example, the length of the coating material M in the short axis direction D3 is 0.5 mm or more and 1 mm or less, and the length of the coating material M in the long axis direction D2 is 3 mm or more and 4 mm or less.

[0078] exist Fig.11 In the example (b), the holding portion 11 extends linearly from the front end of the flat surface M1 toward the rear. For example, the length of the holding portion 11 in the axial direction D1 is not less than 20% and not more than 50% of the length of the flat surface M1 in the axial direction D1. However, the length of the holding portion 11 in the axial direction D1 is not limited to the above example and can be appropriately changed.

[0079] The tubular component 10 has a front end 10h. The front end 10h is an end on the axial direction D1 of the tubular component 10, and is located on the long axis direction D2 of the tubular component 10. In the present embodiment, the length of the retaining portion 11 on one side on the long axis direction D2 on the axial direction D1 is different from the length of the retaining portion 11 on the other side on the long axis direction D2 on the axial direction D1. More specifically, the length of the retaining portion 11 on the side of the front end 10h of the tubular component 10 is longer than the length of the retaining portion 11 on the opposite side of the front end 10h of the tubular component 10.

[0080] Fig.12 1 is a diagram showing the cylindrical member 10 as viewed from the front. Fig.11 (a) Fig.11 (b) and Fig.12 As shown, the shape of the cylindrical hole 10c of the holding cylindrical portion 13 observed from the front is set to a flat shape having a major axis L11 and a minor axis L12. As an example, the shape of the cylindrical hole 10c of the holding cylindrical portion 13 observed from the front is a rectangle having a long side extending in the major axis direction D2 and a short side extending in the minor axis direction D3.

[0081] For example, the retaining cylinder 13 has a first side portion 13b extending in the axial direction D1 and the long axis direction D2, and a second side portion 13c extending in the axial direction D1 and the short axis direction D3. The retaining cylinder 13 has a pair of second side portions 13c arranged along the long axis direction D2. For example, the second side portion 13c is flat.

[0082] The first side portion 13b has a flat surface 13d extending in the axial direction D1 and the long axis direction D2, and a convex portion 13f protruding from the flat surface 13d. The flat surface 13d includes a first flat surface 13d1 located on the front end 10h side of the tubular member 10, and a second flat surface 13d2 extending rearward from the first flat surface 13d1. The second flat surface 13d2 is located on the end side of the short axis direction D3 compared to the first flat surface 13d1. The retaining cylinder 13 has a step portion 13g located between the first flat surface 13d1 and the second flat surface 13d2.

[0083] The cylindrical member 10 enters the recess 2p (see Figure 5 (a) and Figure 5 More specifically, the tubular member 10 is engaged with the front tube 2 in the rotational direction by causing the second side portion 13c of the retaining tube 13 to enter the first recess 2p1 and the convex portion 13f of the retaining tube 13 to enter the second recess 2p2.

[0084] The retaining cylinder 13 has a pair of convex portions 13f, and the pair of convex portions 13f are arranged along the minor axis direction D3. Thus, when viewed from the front, the tubular member 10 is in a cross shape. The convex portion 13f has a first portion 13f1 located on one side of the major axis direction D2, and a second portion 13f2 located on the other side of the major axis direction D2 and having a lower protruding height than the first portion 13f1.

[0085] The length of the first portion 13f1 in the long axis direction D2 is longer than the length of the second portion 13f2 in the long axis direction D2. The center position of the convex portion 13f in the long axis direction D2 is toward one side in the long axis direction D2 (at Fig.12 The center position of the second recess 2p2 in the longitudinal direction D2 is offset to one side in the longitudinal direction D2 (in the center of the front tube 2) compared to the center position in the longitudinal direction D2 of the front tube 2. Figure 5 Therefore, it is possible to avoid inserting the tubular member 10 into the front tube 2 in a state where the direction in the short-axis direction D3 is reversed.

[0086] Fig.13 FIG. 1 is a three-dimensional diagram of the connection portion 12 and the flange portion 14 after enlarging. Fig.13 As shown, the connection portion 12 protrudes from the flange portion 14 in the opposite direction (rearward) of the holding cylinder portion 13. The connection portion 12 has a protrusion 12c protruding rearward from the flange portion 14 and a hole 12b extending forward from a rear end 12d of the protrusion 12c and through which the pressing member 7 passes.

[0087] The hole portion 12b includes a first hole portion 12f that penetrates the protruding portion 12c in the long axis direction D2, and a second hole portion 12g that intersects the first hole portion 12f and extends in the short axis direction D3. The second hole portion 12g protrudes from the center of the first hole portion 12f in the long axis direction D2 toward the short axis direction D3. For example, when viewed from the rear, the first hole portion 12f and the second hole portion 12g are in a cross shape.

[0088] The pressing member 7 is inserted into the hole 12b from the rear. More specifically, the first plate-shaped portion 7k (see Fig. 9 (b)) is inserted into the first hole 12f, and the second plate-shaped portion 7p of the pressing member 7 is inserted into the second hole 12g. By inserting the pressing member 7 into the hole 12b in this way, the pressing member 7 and the tubular member 10 are engaged in the rotation direction (rotatably in sync).

[0089] Fig.14 2 is a cross-sectional view of a portion of the retaining cylinder 13 where the convex portion 13f is formed when the portion is cut along a plane perpendicular to the axial direction D1. Fig.12 as well as Fig.14As shown, the cylindrical hole 10c of the cylindrical member 10 includes a first cylindrical hole portion 10f extending rearward from the front end 10h, and a second cylindrical hole portion 10g located behind the first cylindrical hole portion 10f and inside the portion of the cylindrical member 10 where the convex portion 13f is formed.

[0090] The cross section of the first barrel hole portion 10f when cut by a plane orthogonal to the axial direction D1 is a flat shape extending in the major axis direction D2 and the minor axis direction D3. The cross section of the second barrel hole portion 10g when cut by a plane orthogonal to the axial direction D1 is a cross shape. For example, a portion (front side portion) of the coating material M passes through the first barrel hole portion 10f, and the remaining portion (rear side portion) of the coating material M and the pushing member 7 pass through the second barrel hole portion 10g. Thus, the coating material M and the pushing member 7 are configured to be able to move forward in the barrel hole 10c.

[0091] Next, refer to Figure 1 (a) Figure 1 (b) Figure 2 (a)~ Figure 2 (c) and Figure 3 , while explaining the operation of each part of the coating container 1 when the coating container 1 is used. First, if the rear cylinder 3 is rotated relative to the front cylinder 2 in one direction (for example, clockwise), the threaded cylinder 5 rotates synchronously with the rear cylinder 3 and the screwing action of the first external thread 5b of the threaded cylinder 5 and the first internal thread 2v (first screwing portion 16) of the front cylinder 2 is exerted, and the threaded cylinder 5 moves forward relative to the front cylinder 2.

[0092] When the threaded barrel 5 advances relative to the front barrel 2, the tubular member 10 and the coating material M advance together with the threaded barrel 5. The advancing tubular member 10 and the coating material M protrude forward from the front end opening 2b of the front barrel 2. Then, when the rear barrel 3 is relatively rotated in one direction relative to the front barrel 2 in a state where the threaded barrel 5 advances and reaches the advancement limit, the rear barrel 3, the tail plug 8, and the moving body 6 are relatively rotated in one direction relative to the threaded barrel 5 and the screwing action of the second internal thread 5r of the threaded barrel 5 and the second external thread 6b (second screwing portion 17) of the moving body 6 is exerted.

[0093] Once the screwing action of the second screwing portion 17 takes effect, the movable body 6, the pressing member 7, and the coating material M move forward relative to the threaded barrel 5 and the tubular member 10. As a result, the coating material M is sent forward relative to the tubular member 10, and the coating material M is provided for use. In addition, if the rear barrel 3 is rotated in a direction opposite to one direction (for example, counterclockwise) relative to the front barrel 2, the threaded barrel 5 rotates synchronously with the rear barrel 3 and the screwing action of the first external thread 5b of the threaded barrel 5 and the first internal thread 2v (first screwing portion 16) of the front barrel 2 takes effect, and the threaded barrel 5 retreats relative to the front barrel 2.

[0094] Once the threaded barrel 5 retreats relative to the front barrel 2, the tubular member 10 and the coating material M retreat together with the threaded barrel 5. It should be noted that, as described above, since the threaded barrel 5 does not rotate in the opposite direction relative to the rear barrel 3 (the wall surface 5p4 abuts against the protruding portion 3c), the rear barrel 3, the tail plug 8, and the moving body 6 do not rotate relative to the threaded barrel 5 in the opposite direction. Therefore, during the rotation in the opposite direction, the screwing action of the second screwing portion 17 does not work, and the coating material M is not sent back to the rear relative to the tubular member 10.

[0095] Next, the effects obtained by the coating container 1 according to this embodiment will be described. Figure 3 , Figure 4 as well as Fig.11 As shown in (b), the coating container 1 includes a cylindrical member 10 for storing the coating material M, and a delivery mechanism 15 for delivering the coating material M stored in the cylindrical member 10, and the delivery mechanism 15 delivers the coating material M so that the coating material M protrudes from the cylindrical member 10. The shape of the cylindrical hole 10c of the cylindrical member 10 observed along the axial direction D1 and the shape of the coating material M observed along the axial direction D1 are set to be a flat shape having a major axis and a minor axis.

[0096] The coating material M has a flat surface M1 extending in the axial direction D1 and the long axis direction D2, and the tubular member 10 has a retaining portion 11 that holds the coating material M by contacting the flat surface M1. The retaining portion 11 that contacts the flat surface M1 of the coating material M extends from one end side in the axial direction D1 of the flat surface M1 to the other end side. Therefore, by extending the retaining portion 11 from one side in the axial direction D1 of the flat surface M1 to the other side in a state of contacting the flat surface M1, the retaining portion 11 can hold the coating material M in a wide range from one side in the axial direction D1 to the other side. Therefore, even when holding the coating material M in a flat shape, by holding the coating material M in a range from one side in the axial direction D1 of the flat surface M1 to the other side, deformation and breakage of the coating material M can be suppressed.

[0097] In the present embodiment, the cross section of the coating material M perpendicular to the axial direction D1 is flat, and the cross section of the cylindrical hole 10c perpendicular to the axial direction D1 is flat from one end of the flat surface M1 in the axial direction D1 to the other end. That is, the entirety of the flat surface M1 in the axial direction D1 is opposite to the inner peripheral surface 10d of the cylindrical hole 10c having a flat shape. Therefore, the vibration of the coating material M in the cylindrical hole 10c can be suppressed and the coating material M can be well held by the cylindrical hole 10c, so that the deformation and breakage of the coating material M can be more reliably suppressed.

[0098] In the present embodiment, the retaining portion 11 is in the shape of a protrusion protruding toward the flat surface M1. The tubular member 10 has a plurality of retaining portions 11 arranged along the major axis direction D2 and along the minor axis direction D3. The coating material M is sandwiched between the plurality of retaining portions 11 arranged along the minor axis direction D3. In this case, the coating material M is held in a state sandwiched between a pair of retaining portions 11 arranged along the minor axis direction D3, so the coating material M can be more firmly held by the plurality of retaining portions 11. As a result, deformation and breakage of the coating material M can be more reliably suppressed.

[0099] In the present embodiment, the coating container 1 comprises: a front tube 2 that accommodates a cylindrical component 10 and has a first internal thread 2v inside; a rear tube 3 that is relatively rotatably connected to the front tube 2; a threaded tube 5 that is provided inside the rear tube 3 and has a first external thread 5b that is screwed with the first internal thread 2v and a second internal thread 5r formed on the inner surface; and a movable body 6 that advances inside the threaded tube 5 and has a second external thread 6b that is screwed with the second internal thread 5r.

[0100] The delivery mechanism 15 includes a first screwing portion 16 and a second screwing portion 17. The first screwing portion 16 advances the threaded barrel 5 relative to the front barrel 2 by screwing the first external thread 5b and the first internal thread 2v when the threaded barrel 5 rotates relative to the front barrel 2. The second screwing portion 17 advances the movable body 6 relative to the threaded barrel 5 by screwing the second internal thread 5r and the second external thread 6b when the rear barrel 3 rotates relative to the threaded barrel 5. When the rear barrel 3 rotates relative to the front barrel 2 in one direction, the threaded barrel 5 rotates synchronously with the rear barrel 3, and by advancing the threaded barrel 5 relative to the rear barrel 3 to the forward limit, the tubular member 10 and the coating material M protrude forward from the front barrel 2.

[0101] When the rear barrel 3 is relatively rotated in one direction relative to the front barrel 2 in a state where the threaded barrel 5 has reached the limit of advancement, the rear barrel 3 is relatively rotated relative to the threaded barrel 5 and the movable body 6 is advanced relative to the threaded barrel 5, thereby delivering the coating material M relative to the tubular member 10. In this case, since the coating material M can be advanced together with the tubular member 10 by relatively rotating the rear barrel 3 in one direction relative to the front barrel 2, deformation and breakage of the coating material M when delivering the coating material M can be suppressed. In addition, the coating material M is first delivered relative to the tubular member 10 in a state where the threaded barrel 5 has reached the limit of advancement and the tubular member 10 and the coating material M protrude forward from the front barrel 2. Therefore, the amount of the coating material M delivered relative to the tubular member 10 can be reduced, and thus breakage of the coating material M during coating can be more reliably suppressed.

[0102] Next, various modifications of the coating container according to the present invention will be described. Fig.15Next, a coating container according to a first modification will be described. Fig.15 This is a perspective view showing the tail plug 18 involved in the first modified example. In the above embodiment, the tail plug 8 having the first holding portion 8b for holding the movable body 6 and the second holding portion 8f for holding the coating tool 9 is described. However, the coating container may also be provided with a tail plug 18 that does not have the second holding portion 8f for holding the coating tool 9 instead of the tail plug 8. The coating container involved in the first modified example has the tail plug 18 but does not have the cover 4 and the coating tool 9.

[0103] The coating container according to the various modified examples described below has a part of the same structure as the coating container 1. The coating container according to the first modified example is the same as the coating container 1 except that it has a tail plug 18 instead of the tail plug 8 and does not have a cover 4 and a coating tool 9. Therefore, in the following description, the same symbols as in the above description are used for the same structure as the above structure, and the description thereof is appropriately omitted.

[0104] The tail plug 18 has a first holding portion 18b that holds the movable body 6. The first holding portion 18b has a rod-shaped portion 18c extending forward from the engaging portion 8c, and a convex portion 18d protruding radially outward from the rod-shaped portion 18c and extending in the axial direction D1. The first holding portion 18b has a plurality of convex portions 18d, and the plurality of convex portions 18d are arranged in the circumferential direction.

[0105] The first holding portion 18b enters the moving body 6 from the rear. The convex portion 18d and the concave portion 6f of the moving body 6 (see Figure 8 (b)) is engaged in the rotational direction. The convex portion 18d extends linearly along the axial direction D1 and has a width in the circumferential direction. The convex portion 18d has a front end portion 18g whose width narrows as it approaches the front end 18f of the convex portion 18d. At the front end portion 18g, the width of the convex portion 18d widens as it moves away from the front end 18f. Since the convex portion 18d has the front end portion 18g, the first retaining portion 18b can be easily inserted into the movable body 6.

[0106] Next, refer to Figure 16 to Figure 18 While explaining the coating container involved in the second modified example. The coating container involved in the second modified example has a cylindrical component 20 composed of two parts instead of the cylindrical component 10 composed of one part. The cylindrical component 20 includes a first structural component 21 and a second structural component 22 joined to the first structural component 21. The first structural component 21 and the second structural component 22 each have the above-mentioned holding portion 11. The first structural component 21 has the above-mentioned flange portion 14 and the connecting portion 12.

[0107] Fig.16 It is a perspective view showing the first structural member 21, the second structural member 22, and the coating material M. Fig.17 2 is a perspective view showing the first structural member 21. Fig.16 as well as Fig.17 As shown, the first structural member 21 has a first recessed portion 21b for placing the coating material M. The first recessed portion 21b has a concave shape into which the coating material M enters.

[0108] The first recessed portion 21b is divided by a bottom portion 21c extending in the axial direction D1 and the long axis direction D2, and a pair of side portions 21d extending upward from both ends of the bottom portion 21c in the long axis direction D2. The coating material M placed on the first recessed portion 21b is covered by the second structural member 22, and the second structural member 22 is joined to the first structural member 21 in a state where the coating material M is covered.

[0109] The first structural member 21 and the second structural member 22 are joined to each other in a direction perpendicular to the axial direction D1. In the second modified example, the first structural member 21 and the second structural member 22 are joined to each other in a state of being aligned in the short-axis direction D3. Fig.18 The cross section of the tubular member 20 obtained by joining the second structural member 22 and the first structural member 21 is shown along a plane perpendicular to the axial direction D1.

[0110] like Figure 16 to Figure 18 As shown, the first structural member 21 has a first joint portion 23 joined to the second structural member 22, and the second structural member 22 has a second joint portion 24 joined to the first joint portion 23. The first joint portion 23 protrudes toward both end sides in the long axis direction D2 in each of a pair of side portions 21d of the first structural member 21. The first joint portion 23 extends along the axial direction D1.

[0111] The first joint portion 23 has an inclined surface 23b extending obliquely downward from the side portion 21d, a top surface 23c extending downward from the lower end of the inclined surface 23b, and a lower surface 23d extending from the lower end of the top surface 23c to the side portion 21d. The first structural member 21 has a plurality of first joint portions 23, and the plurality of first joint portions 23 are arranged along the axial direction D1. Furthermore, the plurality of first joint portions 23 are arranged along the long axis direction D2.

[0112] The length (width) of the second structural member 22 in the long-axis direction D2 is longer than the length (width) of the first structural member 21 in the long-axis direction D2. The second structural member 22 has a first recessed portion 21b that seals the first structural member 21 and a second recessed portion 22b that accommodates the first structural member 21. The second recessed portion 22b is divided by a top portion 22c extending in the axial direction D1 and the long-axis direction D2, and a pair of side portions 22d extending downward from both ends of the top portion 22c in the long-axis direction D2.

[0113] The second joint portion 24 extends along the axial direction D1. The second joint portion 24 protrudes toward the center side of the long axis direction D2 in each of the pair of side portions 22d of the second structural member 22. The second joint portion 24 has a bottom surface 24c of a hole 24b that penetrates the top portion 22c in the short axis direction D3 and is formed on the center side of the side portion 22d in the long axis direction D2, a top surface 24d extending downward from the end of the bottom surface 24c on the center side in the long axis direction D2, and an inclined surface 24f extending obliquely downward from the lower end of the top surface 24d toward the side portion 22d.

[0114] The second structural member 22 has a plurality of second engaging portions 24, and each second engaging portion 24 engages with each first engaging portion 23. More specifically, when the first structural member 21 enters the second recess 22b of the second structural member 22, the inclined surface 23b of the first engaging portion 23 abuts against the inclined surface 24f of the second engaging portion 24. Then, the first engaging portion 23 passes over the second engaging portion 24 upward, and the second structural member 22 engages with the first structural member 21 in a state where the lower surface 23d faces the upper side of the bottom surface 24c.

[0115] As described above, the tubular member 20 according to the second modified example includes the first structural member 21 and the second structural member 22 joined to the first structural member 21. In this case, the coating material M can be held between the first structural member 21 and the second structural member 22. Therefore, by joining the first structural member 21 and the second structural member 22 in a state where the coating material M is located between the first structural member 21 and the second structural member 22, the coating material M can be easily loaded relative to the tubular member 20.

[0116] In the second modification, the first structural member 21 and the second structural member 22 are joined to each other in a direction perpendicular to the axial direction D1. In this case, the coating material M can be held between the first structural member 21 and the second structural member 22 that are opposite to each other in a direction perpendicular to the axial direction D1, so that the coating material M can be easily loaded and held.

[0117] The first structural member 21 has a first joint portion 23 joined to the second structural member 22, and the second structural member 22 has a second joint portion 24 joined to the first joint portion 23, and the first joint portion 23 and the second joint portion 24 extend along the axial direction D1. In this case, since the first joint portion 23 and the second joint portion 24 extend along the axial direction D1, the second structural member 22 can be easily joined to the first structural member 21.

[0118] The first structural member 21 has a first recessed portion 21b that accommodates the coating material M and extends in the axial direction D1, and the second structural member 22 has a second recessed portion 22b that seals the first recessed portion 21b that accommodates the coating material M and accommodates the first structural member 21. In this case, the first recessed portion 21b can be sealed and the first structural member 21 can be accommodated in the second recessed portion 22b in a state where the coating material M is accommodated in the first recessed portion 21b of the first structural member 21. Therefore, the coating material M can be easily loaded and the second structural member 22 can be joined to the first structural member 21.

[0119] In the above, as the second modified example, an example in which the first structural member 21 and the second structural member 22 are joined to each other in a direction orthogonal to the axial direction D1 is described. However, the first structural member and the second structural member may be joined to each other in a direction intersecting the axial direction D1 (for example, a direction extending obliquely with respect to the axial direction D1) instead of in a direction orthogonal to the axial direction D1. In this way, the direction in which the first structural member and the second structural member are joined is not particularly limited.

[0120] Fig.19 1 is a cross-sectional view showing a cylindrical member 30 having a first structural member 31 and a second structural member 32 according to a third modification. Fig.19 As shown, the tubular member 30 is different from the tubular member 20 according to the second modification in that it has a holding portion 33 having a shape different from that of the holding portion 11. The first structural member 31 and the second structural member 32 each have a holding portion 33 that contacts the flat surface M1 of the coating material M.

[0121] The holding portion 33 is a protruding curved surface that contacts the flat surface M1. The holding portion 33 is formed at the bottom 21c and the top 22c. The holding portion 33 protrudes toward the center of the tubular member 30 in the short axis direction D3 as it moves toward the center of the tubular member 30 in the long axis direction D2.

[0122] As described above, in the tubular member 30 according to the third modified example, since the coating material M is held in a state where the retaining portion 33 is in contact with the flat surface M1 of the coating material M inside the tubular member 30, the coating material M is firmly held and deformation and breakage of the coating material M can be suppressed. Therefore, the tubular member 30 can also obtain the same effects as those of the tubular members 10 and 20 described above.

[0123] Fig. 20 The present invention is an exploded perspective view showing a coating container 41 according to a fourth modification. The coating container 41 has a tubular component 50 different from the tubular component 10 described above. The tubular component 50 has a first structural component 51 housed in the front tube 2 and a second structural component 52 inserted in the middle tube 42 connected to the rear tube 3.

[0124] The first structural member 51 and the second structural member 52 are joined to each other along the axial direction D1. The first structural member 51 has a housing portion 53 into which the second structural member 52 enters from behind. The second structural member 52 has an insertion portion 54 into the housing portion 53. The housing portion 53 and the insertion portion 54 are, for example, rectangular box-shaped.

[0125] The storage portion 53 has a through hole 53b that penetrates the storage portion 53. The through hole 53b penetrates the side surface 53c of the storage portion 53 extending in the axial direction D1 and the long axis direction D2 in the short axis direction D3. The through hole 53b is rectangular. The insertion portion 54 has a convex portion 54b that enters the through hole 53b.

[0126] The convex portion 54b protrudes outward in the short-axis direction D3 from the side portion 54c of the insertion portion 54 extending in the axial direction D1 and the long-axis direction D2. The convex portion 54b has an inclined surface 54b1 extending obliquely toward the radial outside relative to the side portion 54c as it moves toward the rear, and a top surface 54b2 extending along the axial direction D1 from the end of the inclined surface 54b1 opposite to the side portion 54c.

[0127] Fig.21 (a) Fig.21 (b) and Fig.21 (c) is a perspective view showing the process of loading the coating material M into the cylindrical member 50 and assembling the coating container 41. Fig.21 (a) and Fig.21 As shown in (b), the second structural member 52 is inserted into the middle cylinder 42 from the front, and the coating material M is inserted into the second structural member 52 from the front.

[0128] At this time, the front end M4 of the coating material M is formed to protrude from the second structural member 52. Then, as shown in FIG. Fig.21 (b) and Fig.21 As shown in (c), the first structural member 51 provided with a plurality of holding portions 11 for holding the coating material M is joined to the second structural member 52. At this time, the insertion portion 54 enters the storage portion 53, and the inclined surface 54b1 of the insertion portion 54 abuts against the inner surface of the storage portion 53. Then, the insertion portion 54 moves forward relative to the storage portion 53, and the first structural member 51 is joined to the second structural member 52 in a state where the convex portion 54b enters the through hole 53b. Thereafter, the front cylinder 2 is mounted on the middle cylinder 42 in a manner covering the second structural member 52 and the first structural member 51, thereby completing the assembly of the coating container 41.

[0129] As described above, in the coating container 41 involved in the fourth modified example, the first structural member 51 and the second structural member 52 are joined to each other along the axial direction D1. In this case, since the first structural member 51 is joined to the second structural member 52 along the axial direction D1, the first structural member 51 can be easily joined to the second structural member 52.

[0130] Fig. 22 It is a perspective view showing the front tube 2, the rear tube 3, the tubular member 70, and the coating material M of the coating container 61 according to the fifth modification. Fig.23 (a) is a perspective view showing the first structural member 71 constituting the tubular member 70. Fig.23 (b) is a perspective view showing the second structural member 72 constituting the cylindrical member 70. Fig. 22 , Fig.23 (a) and Fig.23 As shown in (b), the tubular member 70 includes a first structural member 71 and a second structural member 72 joined to the first structural member 71. The first structural member 71 and the second structural member 72 are joined to each other along the short-axis direction D3.

[0131] The cylindrical member 70 has a leaf spring portion 75 in contact with the coating material M, instead of the above-mentioned protruding retaining portion 11. In the coating container 61, the leaf spring portion 75 functions as a retaining portion. The leaf spring portion 75 is configured to be elastically deformable along the thickness direction (minor axis direction D3) of the coating material M. For example, the leaf spring portion 75 includes a first leaf spring portion 76 of the first structural member 71 and a second leaf spring portion 77 of the second structural member 72. The first leaf spring portion 76 is divided by a slit 76b. The slit 76b penetrates the first structural member 71 in the minor axis direction D3.

[0132] The slit 76b includes a pair of first slits 76b1 and a second slit 76b2 connecting the pair of first slits 76b1. The first slit 76b1 extends in the axial direction D1, and the pair of first slits 76b1 are arranged along the long axis direction D2. The second slit 76b2 extends in the long axis direction D2 so that the front ends of the pair of first slits 76b1 are connected to each other. The slit 76b has a U-shape by having a pair of first slits 76b1 and a second slit 76b2.

[0133] The second leaf spring portion 77 is similar to the first leaf spring portion 76 and is divided by a slit 77b that penetrates the second structural member 72 in the short axis direction D3. The slit 77b includes a pair of first slits 77b1 and a second slit 77b2 that connects the pair of first slits 77b1 to each other. The structures of the first slit 77b1 and the second slit 77b2 are similar to the structures of the first slit 76b1 and the second slit 76b2 described above.

[0134] The first structural member 71 has a bottom 71b extending in the axial direction D1 and the long-axis direction D2, and a pair of side portions 71c protruding in the same direction from both ends of the bottom 71b in the long-axis direction D2. The first leaf spring portion 76 protrudes in a curved shape toward the direction in which the side portions 71c protrude as it moves toward the center of the axial direction D1 of the first leaf spring portion 76. The second structural member 72 also has the same bottom 72b and side portions 72c as the first structural member 71, and the second leaf spring portion 77 protrudes in a curved shape toward the direction in which the side portions 72c protrude as it moves toward the center of the axial direction D1 of the second leaf spring portion 77.

[0135] In the tubular member 70 constructed as described above, the coating material M is inserted from the front to load the coating material M. When the first structural member 71 and the second structural member 72 are joined, the central portion of the leaf spring portion 75 in the axial direction D1 protrudes in a curved shape toward the central side in the short-axis direction D3 of the tubular member 70.

[0136] Therefore, when the coating material M is inserted into the cylindrical hole 10c of the cylindrical member 70, the coating material M abuts against the first leaf spring portion 76 and the second leaf spring portion 77, and the coating material M is inserted while stretching the first leaf spring portion 76 and the second leaf spring portion 77 toward both ends of the short axis direction D3. In the state where the coating material M is inserted, the coating material M is pressed from both sides of the short axis direction D3 by the first leaf spring portion 76 and the second leaf spring portion 77, so that the coating material M can be firmly held in the cylindrical hole 10c.

[0137] As described above, in the coating container 61 involved in the fifth modified example, the shape of the cylindrical hole 10c of the cylindrical member 70 observed along the axial direction D1 and the shape of the coating material M observed along the axial direction D1 are set to a flat shape having a major axis and a minor axis, and the coating material M has a flat surface extending in the axial direction D1 and the major axis direction D2. The cylindrical member 70 has a holding portion that holds the coating material M by contacting the flat surface, and the holding portion is a leaf spring portion 75 divided by slits 76b and 77b formed in the cylindrical member 70. The leaf spring portion 75 contacts the coating material M and elastically deforms in the thickness direction of the cylindrical member 70. Therefore, by making the leaf spring portion 75 that undergoes elastic deformation contact with the flat surface, the coating material M can be held in a wide range. Therefore, even in the case of holding the coating material M in a flat shape, by making the leaf spring portion 75 contact with the flat surface to hold the coating material M, the coating material M can be held with a moderate holding force, and the deformation and breakage of the coating material can be suppressed. Therefore, in the coating container 61 according to the fifth modification, the same operational effects as those of the coating container 1 according to the above-described embodiment and the like can be obtained.

[0138] It should be noted that, in the fifth modification, an example in which the leaf spring portion 75 is formed by the first leaf spring portion 76 of the first structural member 71 and the second leaf spring portion 77 of the second structural member 72 is described. However, the leaf spring portion 75 may be formed only in one of the first structural member 71 and the second structural member 72. Furthermore, the above-mentioned tubular member 10, tubular member 20, tubular member 30, or tubular member 50 may also have the leaf spring portion 75.

[0139] In the tubular component 70 involved in the fifth modification, the first structural component 71 and the second structural component 72 are joined to each other along a direction (short axis direction D3) orthogonal to the axial direction D1. However, in the tubular component involved in the fifth modification having the leaf spring portion 75, the first structural component and the second structural component may be joined to each other along the axial direction D1, or may be joined to each other along a direction intersecting the axial direction D1 (for example, a direction extending obliquely with respect to the axial direction D1). Thus, in the fifth modification, the direction in which the first structural component and the second structural component are joined is not particularly limited.

[0140] Above, the embodiment and various modifications of the coating container involved in the present invention are described. However, the coating container involved in the present invention is not limited to the above-mentioned embodiment or modification, and can also be further modified within the scope of the subject matter described in the claims. That is, the shape, size, material, quantity and configuration of each part of the coating container involved in the present invention can be appropriately changed within the scope of the above-mentioned subject matter. In the foregoing, the embodiment and the first to fifth modifications of the coating container are described. The coating container involved in the present invention can also be a coating container composed of a part of the form selected from the embodiment and the first to fifth modifications, and the remaining part different from the form. In this way, the above-mentioned embodiment and the first to fifth modifications can be appropriately combined.

[0141] For example, in the above-described embodiment, the coating container 1 is described as including the front cylinder 2, the rear cylinder 3, the threaded cylinder 5, and the movable body 6, and the delivery mechanism 15 has the first screw-engaged portion 16 for advancing the threaded cylinder 5 relative to the front cylinder 2, and the second screw-engaged portion 17 for advancing the movable body 6 relative to the threaded cylinder 5. However, the coating container may be a container that does not include at least any one of the front cylinder 2, the rear cylinder 3, the threaded cylinder 5, and the movable body 6, and the delivery mechanism may be a mechanism that does not include at least any one of the first screw-engaged portion 16 and the second screw-engaged portion 17.

[0142] In the above embodiment, the coating container 1 is described as having a delivery mechanism 15 that delivers the coating material M by the relative rotation of the rear cylinder 3 in one direction relative to the front cylinder 2. However, the coating container may also be a coating container having a delivery mechanism that does not deliver by relative rotation. That is, the coating container may also have a delivery mechanism that is a mechanical push-out mechanism such as a knock type, and the painting material is pushed out by the delivery mechanism, or may have an extrusion type delivery mechanism instead of relative rotation.

[0143] In the above embodiment, the coating container 1 having the coating material M as a cosmetic is described. However, the coating material may be a substance other than a cosmetic.

Claims

1. A coating container for delivering a coating material, comprising: a cylindrical member having a cylindrical hole for accommodating the coating material and an opening through which the coating material is exposed; and a delivery mechanism that advances the coating material accommodated in the cylindrical hole and causes the coating material to protrude from the opening, The shape of the cylindrical hole observed along the axial direction, which is the direction in which the axis of the cylindrical member extends, and the shape of the coating material observed along the axial direction are set to be a flat shape having a major axis and a minor axis, The coating material has a thickness in the short axis direction which is the direction in which the short axis extends, The coating material has a flat surface extending in the long axis direction, which is the direction in which the long axis extends, and in the axial direction. The cylindrical member has a holding portion that holds the coating material by contacting the flat surface. The holding portion extends from one end side of the flat surface in the axial direction to the other end side in a state of being in contact with the flat surface.

2. A coating container for delivering a coating material, comprising: a cylindrical member having a cylindrical hole for accommodating the coating material and an opening through which the coating material is exposed; and a delivery mechanism that advances the coating material accommodated in the cylindrical hole and causes the coating material to protrude from the opening, The shape of the cylindrical hole observed along the axial direction, which is the direction in which the axis of the cylindrical member extends, and the shape of the coating material observed along the axial direction are set to be a flat shape having a major axis and a minor axis, The coating material has a thickness in the short axis direction which is the direction in which the short axis extends, The coating material has a flat surface extending in the long axis direction, which is the direction in which the long axis extends, and in the axial direction. The cylindrical member has a holding portion that holds the coating material by contacting the flat surface. The holding portion is a leaf spring portion divided by a slit formed in the tubular member. The leaf spring portion is in contact with the coating material and elastically deforms in the thickness direction of the tubular member.

3. The coating container according to claim 1, wherein: The holding portion is in the shape of a protrusion protruding toward the flat surface, The cylindrical member has a plurality of the holding portions arranged in the major axis direction and in the minor axis direction, The coating material is sandwiched between the plurality of holding portions arranged along the short-axis direction.

4. The coating container according to claim 1 or 2, wherein: The tubular member includes a first structural member and a second structural member joined to the first structural member.

5. The coating container according to claim 4, wherein: The first structural member and the second structural member are joined to each other in a direction perpendicular to the axial direction.

6. The coating container according to claim 4, wherein: The first structural member and the second structural member are joined to each other along the axial direction.

7. The coating container according to claim 1 or 2, comprising: A front tube, the front tube accommodates the cylindrical member and has a first internal thread inside; a rear cylinder, the rear cylinder being connected to the front cylinder in a relatively rotatable manner; a threaded barrel disposed inside the rear barrel and having a first external thread threadedly engaged with the first internal thread and a second internal thread formed on an inner surface; and a moving body which moves forward in the interior of the threaded barrel and has a second external thread which is threadedly engaged with the second internal thread, The delivery mechanism comprises: a first threading portion, wherein when the threaded barrel rotates relative to the front barrel, the first threading portion causes the threaded barrel to move forward relative to the front barrel through the threading action of the first internal thread and the first external thread; and a second screwing portion, wherein when the rear tube rotates relative to the threaded tube, the second screwing portion causes the movable body to move forward relative to the threaded tube through the screwing action of the second internal thread and the second external thread, When the rear cylinder rotates relative to the front cylinder in one direction, the threaded cylinder rotates synchronously with the rear cylinder, and the threaded cylinder advances relative to the rear cylinder to the advancement limit, thereby causing the tubular member and the coating material to protrude forward from the front cylinder. When the rear cylinder rotates relative to the front cylinder in the one direction when the threaded cylinder reaches the advancement limit, the rear cylinder rotates relative to the threaded cylinder and the movable body advances relative to the threaded cylinder, thereby delivering the coating material relative to the tubular member.
