[0004] Patent Document 1: Japanese Patent Application Publication No. 2000-217635 Summary of the invention

[0005] In the above-mentioned barrel, the annular step portion for installing the temporary cover and the fitting convex portion for installing the container body are formed at different positions. In the above-mentioned barrel, since the annular step portion for installing the temporary cover and the fitting convex portion for installing the container body are formed, there is a problem that the structure becomes complicated. In addition, in the case of having the annular step portion and the fitting convex portion, the exposed concave and convex parts become more, so there is also room for improvement in terms of aesthetics.

[0006] An object of the present invention is to provide a drawing material container cartridge and a drawing material container kit which can have a simple structure and good aesthetics.

[0007] (1) The drawing material container cartridge according to the present invention comprises a cartridge body and a cartridge cover, wherein the cartridge body has a barrel portion for storing the drawing material and is formed into a structure that is detachably mounted on the container body by being inserted into the container body in an axial direction in a direction in which the axis of the barrel portion extends, and the cartridge cover is mounted on the cartridge body by being inserted into the barrel portion in the axial direction. The cartridge body has a first locking portion, and when the cartridge body is mounted on the container body, the first locking portion is locked to the container body in the axial direction. The cartridge cover has a second locking portion, and when the cartridge cover is mounted on the cartridge body, the second locking portion is locked to the first locking portion in the axial direction.

[0008] The drawing material container cartridge comprises a cartridge body and a cartridge cover mounted on the cartridge body. The cartridge body comprises a barrel portion for storing the drawing material, and the barrel portion is inserted into the cartridge cover along the axial direction. The cartridge body is mounted on the container body by being inserted into the container body. The cartridge body comprises a first locking portion, which is locked to the container body in the axial direction. The cartridge cover comprises a second locking portion, which is locked to the first locking portion of the cartridge body in the axial direction. Therefore, the first locking portion of the cartridge body is a portion that is locked to the container body, and is also a portion that is locked by the second locking portion of the cartridge cover. Therefore, the first locking portion of the cartridge body can be commonly used as a portion that is locked to the container body, and a portion that is locked by the cartridge cover. That is, the portion that is locked to the container body and the portion that is locked by the cartridge cover are formed as the first locking portion, so that the structure of the cartridge body can be simplified. By using the first locking portion as a common portion locked to the container body and a portion locked to the cartridge cap, it is possible to reduce the number of uneven portions of the cartridge body, thereby improving the appearance of the cartridge body.

[0009] (2) In the above (1), the barrel body may also have an insertion portion inserted into the container body. The first locking portion may be a step whose diameter increases from the insertion portion, and the step may contact the container body when the barrel body is installed in the container body. In this case, by locking the barrel cover on the step, the barrel cover can be more reliably installed on the barrel body. By making the first locking portion a step, the structure of the first locking portion can be simplified, which is conducive to further simplification of the structure.

[0010] (3) In the above (1) or (2), the barrel may have an inclined surface which is inclined relative to the axial direction in such a manner that the diameter of the barrel increases as the distance from the opening through which the drawing material is exposed increases along the axial direction. In this case, the diameter of the inclined surface of the barrel inserted into the barrel cover decreases as it moves toward the opening. Therefore, the barrel body can be easily inserted into the barrel cover.

[0011] (4) In any of the above (1) to (3), the barrel cover may also have an inner surface extending in the axial direction, a bottom located at one end of the inner surface in the axial direction, and a contact suppression portion formed on the inner surface and suppressing contact between the barrel and the bottom. In this case, the contact between the barrel that accommodates the drawing material and the bottom is suppressed by the contact suppression portion formed on the inner surface of the barrel cover. Therefore, it is possible to suppress contact between the drawing material and the inner surface of the barrel cover.

[0012] (5) The drawing material container kit according to the present invention comprises the drawing material container cartridge and a container body, wherein the cartridge body of the drawing material container cartridge is formed to be detachably mounted on the container body. In the drawing material container kit, the cartridge body of the drawing material container cartridge is detachably mounted on the container body. Therefore, similarly to the drawing material container cartridge, the structure can be made simple and the appearance is good.

[0013] According to the present invention, the structure can be simplified and the appearance can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Hereinafter, embodiments of the drawing material container cartridge and the drawing material container kit according to the present invention will be described with reference to the accompanying drawings. In the description of the accompanying drawings, the same or equivalent elements are marked with the same symbols, and repeated descriptions are appropriately omitted. For ease of understanding, some structures are sometimes simplified or exaggerated in the accompanying drawings, and the dimensional ratios are not limited to those recorded in the accompanying drawings.

[0016] In the present invention, "drawing material" means an article used when drawing an object as a drawing object. "Drawing material" can be a coating material applied to a coated portion as a coating object. "Drawing material" is, for example, a cosmetic. "Cosmetic" is, for example, an eyebrow pencil, an eyeliner, a lipstick, a lip liner, a lip gloss, a beauty stick, or a concealer.

[0017] Figure 1 (a) is a side view showing the drawing material container 1 according to the present embodiment. Figure 1 (b) is a side view showing a state where the cover 2 of the drawing material container 1 is removed from the drawing material container 1. In this embodiment, the drawing material container 1 is described as an example of a drawing material container. Figure 1 (a) and Figure 1 As shown in (b), the drawing material container 1 includes a cap 2, a container body 3, and a cartridge body 11 of a drawing material container cartridge 10.

[0018] Figure 2 for Figure 1 (a) AA line cross-sectional view. Figure 1 (a) Figure 1 (b) and Figure 2 As shown, the cap 2 is in the shape of a bottomed cylinder (eg, a bottomed cylindrical shape). The container body 3 includes, for example, an inner cylinder 4 into which a cylinder body 11 and a threaded cylinder 12 of a drawing material container cylinder 10 are inserted, and an outer cylinder 5 that accommodates a portion of the inner cylinder 4 .

[0019] The drawing material container 1 includes a cap 2, an inner tube 4, and an outer tube 5, and some of the parts are formed into a cylindrical shape. In the drawing material container 1, when the parts are assembled, the directions in which the axes L of the plurality of cylindrical parts extend are consistent. Hereinafter, the direction in which the axes L extend is referred to as the axis direction D1. For example, the axis direction D1 is consistent with the length direction of the drawing material container 1.

[0020] "Front", "front side" and "front" indicate the direction from the container body 3 toward the cover 2 in the axial direction D1, and "rear", "rear side" and "rear" indicate the direction from the cover 2 toward the container body 3 in the axial direction D1. "Radial" indicates the direction toward the axis L or the direction away from the axis L in a plane orthogonal to the axis L. "Radially outward" indicates the direction away from the axis L in the radial direction, and "radially inward" indicates the direction toward the axis L in the radial direction. "Circumferential" indicates the direction along a ring centered on the axis L (rotational direction). In the present embodiment, the direction in which the drawing material is fed is the front (advancing direction), and the opposite direction is the rear.

[0021] The drawing material container 1 is in the shape of a rod extending along the axial direction D1. The drawing material container 1 delivers the drawing material M. For example, the drawing material container 1 is a pen-shaped container that delivers (pushes out) the drawing material M contained in the drawing material container 1. The drawing material M is, for example, in a solid state. In the present embodiment, the drawing material M is a rod-shaped cosmetic extending along the axial direction D1. As an example, the drawing material M may be an eyebrow cream, in which case the drawing material container 1 is an eyebrow cream application container.

[0022] For example, the outer tube 5 is in the shape of a bottomed tube. The outer tube 5 has, for example, a first convex portion 5b that protrudes from the inner surface of the outer tube 5 toward the radial inner side of the outer tube 5 and extends along the axial direction D1, and a second convex portion 5c that protrudes from the inner surface of the outer tube 5 toward the radial inner side of the outer tube 5 and is located in front of the first convex portion 5b.

[0023] For example, the outer cylinder 5 has a plurality of first protrusions 5b and a plurality of second protrusions 5c, and the plurality of first protrusions 5b and the plurality of second protrusions 5c are arranged along the circumferential direction of the outer cylinder 5. For example, the height of the second protrusion 5c toward the radial inner side is lower than the height of the first protrusion 5b toward the radial inner side. The second protrusion 5c is a portion engaged with the threaded cylinder 12 in the circumferential direction. The outer cylinder 5 has a first annular recess 5d recessed toward the radial outer side of the outer cylinder 5 at the front end of the outer cylinder 5, and a second annular recess 5f recessed toward the radial outer side of the outer cylinder 5 behind the first annular recess 5d. The first annular recess 5d and the second annular recess 5f are portions engaged with the inner cylinder 4.

[0024] For example, the inner tube 4 has an insertion portion 4b inserted into the outer tube 5, and an exposed portion 4c protruding forward from the outer tube 5. The insertion portion 4b has a spring portion 4f, which has elasticity in the axial direction D1 by forming a spiral slit 4d, and an engaging portion 4g, which is located at a position closer to the front than the spring portion 4f and engages with the inner surface of the outer tube 5.

[0025] The engaging portion 4g includes a first annular convex portion 4h and a second annular convex portion 4j. The first annular convex portion 4h protrudes from the outer circumference of the inner tube 4 to the radially outer side of the inner tube 4, and the second annular convex portion 4j protrudes from the outer circumference of the inner tube 4 to the radially outer side of the inner tube 4 behind the first annular convex portion 4h. The first annular convex portion 4h is engaged with the first annular concave portion 5d of the outer tube 5, and the second annular convex portion 4j is engaged with the second annular concave portion 5f of the outer tube 5. The inner tube 4 is engaged with the outer tube 5 in a manner that it cannot move in the axial direction relative to the outer tube 5 and can rotate synchronously. The exposed portion 4c is cylindrical. The inner tube 4 has a convex portion 4k engaged with the cover 2 on the outer circumferential surface of the exposed portion 4c.

[0026] Next, the barrel body 11, the threaded barrel 12, and the movable body 13 of the drawing material container barrel 10 mounted on the container body 3 are described. The barrel body 11, the threaded barrel 12, and the movable body 13 are provided to be attachable and detachable with respect to the container body 3. The drawing material container barrel 10 includes, for example, a barrel body 11, a threaded barrel 12, and a movable body 13, wherein the barrel body 11 has a barrel portion 11b for storing the drawing material M, the threaded barrel 12 has a portion inserted into the barrel body 11, and the movable body 13 moves relative to the threaded barrel 12 along the axial direction D1 inside the threaded barrel 12.

[0027] Figure 3 1 is a front view of the barrel body 11 as viewed from the front. Figure 1 (b) Figure 2 as well as Figure 3 As shown, the barrel body 11 is a front barrel located at the front side of the drawing material container 1. The barrel portion 11b has an opening 11c for exposing the drawing material M and an inclined surface 11r, and the inclined surface 11r is inclined relative to the axial direction D1 so that the diameter of the barrel portion 11b increases as the distance from the opening 11c increases along the axial direction D1.

[0028] The barrel body 11 is inserted into the container body 3 along the axial direction D1, which is the direction in which the axis L of the barrel portion 11b extends, and is detachably mounted on the container body 3. The opening 11c is defined by, for example, a front end 11d of the barrel body 11, a first extension portion 11f that is bent in a raised manner from the front end 11d and extends rearward, and a second extension portion 11g that extends obliquely rearward relative to the rear end of the first extension portion 11f.

[0029] When viewed from the front, the opening 11c is non-circular. When viewed from the front, the opening 11c extends in the long-axis direction D2, which is a direction intersecting the axial direction D1, and the short-axis direction D3, which is a direction intersecting both the axial direction D1 and the long-axis direction D2. The length of the opening 11c in the long-axis direction D2 is longer than the length of the opening 11c in the short-axis direction D3.

[0030] When viewed from the front, the opening 11c includes a first protrusion 11h protruding in the major axis direction D2, a second protrusion 11j protruding in the minor axis direction D3, and a corner portion 11k protruding radially inward of the tube portion 11b between the first protrusion 11h and the second protrusion 11j. For example, the opening 11c includes a pair of first protrusions 11h arranged along the major axis direction D2, and a pair of second protrusions 11j arranged along the minor axis direction D3.

[0031] The first protrusion 11h protrudes from a pair of corners 11k arranged along the short axis direction D3 toward the long axis direction D2. For example, the first protrusion 11h is in a V-shape with rounded corners. The second protrusion 11j protrudes from a pair of corners 11k arranged along the long axis direction D2 toward the short axis direction D3. For example, the second protrusion 11j is in an arc shape.

[0032] For example, the cross section of the drawing material M is non-circular when cut along a plane perpendicular to the axis L. More specifically, the cross section of the drawing material M when cut along a plane perpendicular to the axis L is an oblong (or elliptical) shape having a major axis extending in the major axis direction D2 and a minor axis extending in the minor axis direction D3.

[0033] For example, the shape of the drawing material M observed from the front is the same as the shape of the cross section of the drawing material M when cut along a plane perpendicular to the axis L. The drawing material M when observed along the short axis direction D3 has a front end M1 and a curved portion M2 that curves from the front end M1 toward the long axis direction D2 and the rear and bulges toward the outside of the drawing material M.

[0034] The outer shape of the barrel 11b as viewed from the front is, for example, circular. For example, the barrel 11b includes a single-sided holding portion 11m and a cylindrical holding portion 11p. The single-sided holding portion 11m holds the drawing material M from one side in the long-axis direction D2. The cylindrical holding portion 11p extends backward from the single-sided holding portion 11m and holds the drawing material M in both the long-axis direction D2 and the short-axis direction D3.

[0035] In the one-sided holding portion 11m, the drawing material M is exposed at least on one side of the long axis direction D2, and in the cylindrical holding portion 11p, the drawing material M is not exposed. The shape of the one-sided holding portion 11m observed from the front is, for example, a U-shape. The shape of the barrel body 11 when cut along a plane orthogonal to the axial direction D1 transitions from a non-circular shape to a circular shape as it moves from the one-sided holding portion 11m toward the rear.

[0036] The barrel body 11 has an insertion portion 11q inserted into the container body 3. For example, the insertion portion 11q is cylindrical. The barrel body 11 has a first locking portion 11s that is locked with the container body 3 in the axial direction D1 when mounted on the container body 3. The first locking portion 11s is located at the rear end of the inclined surface 11r, for example.

[0037] For example, the first locking portion 11s is located at the portion of the barrel body 11 where the diameter is most enlarged (the portion of the barrel body 11 where the diameter is the largest). For example, the first locking portion 11s is a step 11t where the diameter is enlarged from the insertion portion 11q. That is, the step 11t protrudes from the insertion portion 11q to the radially outer side of the barrel body 11. When the barrel body 11 is mounted on the container body 3, the step 11t contacts the container body 3 (inner tube 4).

[0038] Figure 4 It is a cross-sectional view when the barrel body 11 is cut by a plane extending in both the axial direction D1 and the long axis direction D2. Figure 4 As shown, the cartridge body 11 (insertion portion 11q) has, for example, an elastic deformation portion 11w that elastically deforms in the radial direction of the cartridge body 11. For example, the cartridge body 11 has a pair of elastic deformation portions 11w that are arranged in the radial direction of the cartridge body 11.

[0039] The elastic deformation portion 11w is formed, for example, in an area surrounded by a pair of first slits 11w1 extending in the axial direction D1 and arranged along the circumferential direction of the barrel body 11, and a second slit 11w2 connecting the front ends of the pair of first slits 11w1 to each other. The first slit 11w1 and the second slit 11w2 penetrate the barrel body 11 in the radial direction, respectively. By providing the barrel body 11 with the elastic deformation portion 11w, the barrel body 11 can be easily assembled to the container body 3.

[0040] The barrel body 11 has a hole portion 11x and a convex portion 11y. The hole portion 11x is recessed toward the radially outer side of the barrel body 11 at the rear side of the inner surface of the barrel body 11, and the convex portion 11y is located at the rear of the hole portion 11x. The hole portion 11x penetrates the barrel body 11 in the radial direction, for example. The hole portion 11x and the convex portion 11y are the parts where the threaded barrel 12 is engaged in the axial direction D1. By engaging the threaded barrel 12 with the hole portion 11x and the convex portion 11y, the threaded barrel 12 is unable to move relative to the barrel body 11 in the axial direction D1 and is relatively rotatable.

[0041] The barrel body 11 has a recess 11v recessed radially outward on the inner surface of the barrel body 11. The recess 11v has a rectangular shape having long sides extending in the axial direction D1 and short sides extending in the circumferential direction of the barrel body 11, for example.

[0042] For example, the barrel body 11 has two recesses 11v, and the two recesses 11v are arranged in the radial direction of the barrel body 11. The recesses 11v are the parts that the moving body 13 engages with in the circumferential direction. By engaging the moving body 13 with the recesses 11v in the circumferential direction, the moving body 13 engages with the barrel body 11 in a manner that allows synchronous rotation.

[0043] Figure 5 1 is a three-dimensional diagram showing the moving body 13. Figure 2 as well as Figure 5 As shown, the movable body 13 includes a drawing material holding portion 13b for holding the drawing material M, and a screw portion 13c extending rearward from the drawing material holding portion 13b. The drawing material holding portion 13b holds the rear side portion of the drawing material M. For example, the drawing material holding portion 13b includes a base portion 13d and a grip portion 13f extending from the base portion 13d to the opposite side of the screw portion 13c.

[0044] For example, the moving body 13 is in the shape of a round rod. The base 13d is located at the front end of the threaded portion 13c. The base 13d has a convex portion 13g that protrudes radially outward from the moving body 13 and extends in the circumferential direction of the moving body 13. The convex portion 13g is aligned with the concave portion 11v (see Figure 4 )The engaging part.

[0045] By engaging the convex portion 13g with the concave portion 11v, the moving body 13 is engaged with the barrel body 11 in a synchronously rotatable manner. For example, the base 13d has a pair of convex portions 13g, and the pair of convex portions 13g are arranged in the radial direction of the moving body 13. The gripping portion 13f has, for example, a pair of arm portions 13h extending forward from the base 13d and extending in the circumferential direction of the moving body 13.

[0046] Figure 6 1 is a cross-sectional view showing the container body 3, the barrel body 11, the moving body 13 and the drawing material M cut along the plane extending in the long axis direction D2 and the short axis direction D3. Figure 2 , Figure 5 as well as Figure 6 As shown, the gripping portion 13f grips the drawing material M by sandwiching the drawing material M between a pair of arm portions 13h. The arm portion 13h has, for example, a protrusion 13j that protrudes radially inwardly of the movable body 13.

[0047] For example, the protrusion 13j is a portion that bites into the drawing material M. By making the protrusion 13j bite into the drawing material M at the gripping portion 13f, the drawing material M can be firmly held. The protrusion 13j has a plurality of (two, for example) protrusions 13k extending in the axial direction D1 and arranged in the circumferential direction of the movable body 13.

[0048] The movable body 13 is provided so as to be movable relative to the threaded barrel 12 in the axial direction D1 while being inserted inside the threaded barrel 12. The drawing material M is fed out from the opening 11c of the barrel body 11 by moving the movable body 13 forward relative to the threaded barrel 12, and the drawing material M is hidden in the opening 11c by moving the movable body 13 backward relative to the threaded barrel 12. The threaded portion 13c is a portion inserted into the threaded barrel 12, and has an external thread 13m that is screwed with the threaded barrel 12 inside the threaded barrel 12.

[0049] Figure 7 (a) is a perspective view showing the threaded barrel 12. Figure 7 (b) is a cross-sectional view of the threaded barrel 12 cut along a plane extending in the axial direction D1. Figure 2 , Figure 7 (a) and Figure 7 As shown in (b), the threaded barrel 12 has a locking portion 12b and an insertion portion 12c, the locking portion 12b is locked with the inner surface of the container body 3 (outer barrel 5), and the insertion portion 12c is located in front of the locking portion 12b and inserted into the interior of the barrel body 11.

[0050] For example, the engaging portion 12b has a convex portion 12d protruding radially outward from the threaded barrel 12. The convex portion 12d is engaged with the second convex portion 5c formed on the inner surface of the outer barrel 5 in the circumferential direction. By engaging the convex portion 12d with the second convex portion 5c in the circumferential direction, the threaded barrel 12 is engaged with the container body 3 (outer barrel 5) in a synchronously rotatable manner. For example, the engaging portion 12b has a plurality of convex portions 12d, and the plurality of convex portions 12d are arranged along the circumferential direction of the threaded barrel 12.

[0051] For example, the threaded barrel 12 has a flange portion 12f located between the engaging portion 12b and the inserting portion 12c. The inserting portion 12c is a portion extending forward from the flange portion 12f, and is, for example, cylindrical. The inserting portion 12c has, for example, an elastic deformation portion 12g that elastically deforms in the radial direction of the threaded barrel 12. For example, the threaded barrel 12 has a pair of elastic deformation portions 12g, and the pair of elastic deformation portions 12g are arranged in the radial direction of the threaded barrel 12.

[0052] The elastic deformation portion 12g is formed, for example, in a region surrounded by a pair of first slits 12g1 extending in the axial direction D1 and arranged in the circumferential direction of the threaded barrel 12, and a second slit 12g2 connecting the rear ends of the pair of first slits 12g1 to each other. The first slit 12g1 and the second slit 12g2 penetrate the threaded barrel 12 in the radial direction, respectively. For example, the elastic deformation portion 12g has a convex portion 12g3 protruding radially outward of the threaded barrel 12.

[0053] The insertion portion 12c has an annular recess 12h and an annular projection 12j located in front of the annular recess 12h. Figure 4 ) is engaged with the annular recess 12h, and the annular protrusion 12j is engaged with the hole 11x of the barrel body 11. By engaging the protrusion 11y with the annular recess 12h and engaging the annular protrusion 12j with the hole 11x, the threaded barrel 12 is engaged with the barrel body 11 in a manner that it cannot move in the axial direction D1 relative to the barrel body 11 but can rotate relatively.

[0054] The threaded barrel 12 has an internal thread 12k formed on the inner surface of the insertion portion 12c. For example, the internal thread 12k protrudes radially inward from the inner surface of the threaded barrel 12 and extends obliquely relative to the circumferential direction of the threaded barrel 12. The internal thread 12k is a portion that is screwed into the external thread 13m of the moving body 13. By screwing the internal thread 12k and the external thread 13m, the threaded barrel 12 and the moving body 13 are screwed and combined.

[0055] The barrel body 11, the threaded barrel 12, and the movable body 13 are provided to be removable relative to the container body 3 when the cap 2 is removed from the container body 3 (inner barrel 4). For example, after the drawing material M stored in the barrel body 11 is used up, the barrel body 11, the threaded barrel 12, and the movable body 13 are removed from the container body 3.

[0056] Then, a new barrel body 11, a threaded barrel 12 and a moving body 13 are installed in the container body 3. For example, Figure 8 (a) and Figure 8 As shown in (b), the drawing material container cartridge 10 has a cartridge cap 15. Before being mounted on the container body 3, the cartridge body 11, the screw cylinder 12, and the moving body 13 are held by the cartridge cap 15.

[0057] Figure 8 (a) is a side view showing the drawing material container cartridge 10 having the cartridge cover 15 . Figure 8 (b) is a cross-sectional view showing the drawing material container cartridge 10 cut along a plane extending in both the axial direction D1 and the long axis direction D2. The cartridge cap 15 is a temporary cap mounted on the cartridge body 11 when the drawing material container cartridge 10 is sold separately as a replacement item.

[0058] The barrel cover 15 is, for example, in the shape of a bottomed barrel (for example, a bottomed cylindrical barrel). The barrel cover 15 is attached to the barrel body 11 by inserting the barrel portion 11b of the barrel body 11 into the barrel cover 15 along the axial direction D1. The barrel cover 15 has an inner surface 15b extending along the axial direction D1, and a bottom 15c located at one end of the inner surface 15b in the axial direction D1.

[0059] The cartridge cover 15 has a contact suppressing portion 15d that suppresses contact between the barrel portion 11b and the bottom portion 15c. The contact suppressing portion 15d is formed on the inner surface 15b. For example, the contact suppressing portion 15d is a rib 15f that protrudes radially inward of the cartridge cover 15 on the inner surface 15b.

[0060] For example, the barrel cover 15 has a plurality of ribs 15f arranged in the circumferential direction of the barrel cover 15. The protruding height of the ribs 15f in the inner surface 15b is, for example, fixed. If the barrel 11b is inserted into the inside from the opening 15k of the barrel cover 15, the inclined surface 11r of the barrel 11b will abut against the ribs 15f, and the barrel 11b cannot move further. This suppresses the contact between the barrel 11b and the bottom 15c.

[0061] The cartridge cap 15 has a second locking portion 15 g that is locked with the first locking portion 11 s of the cartridge body 11 in the axial direction D1 when attached to the cartridge body 11 . Fig. 9 To magnify Figure 8 (b) is a diagram of the second locking portion 15g and the first locking portion 11s. The second locking portion 15g includes, for example, an annular recess 15h and an annular projection 15j located between the annular recess 15h and the opening 15k.

[0062] For example, the annular protrusion 15j is a portion to which the step 11t is engaged. By engaging the annular protrusion 15j with the step 11t, the second engaging portion 15g is engaged with the first engaging portion 11s. For example, the height of the annular protrusion 15j in the inner surface 15b is the same as the height of the rib 15f, and the height of the annular recess 15h is the same as the height of the portion of the inner surface 15b where the rib 15f is not formed.

[0063] For example, in the cross section of the second locking portion 15g cut along a plane extending in the axial direction D1, the annular recess 15h and the annular projection 15j are trapezoidal. In this cross section, at least one of the corners of the annular recess 15h and the annular projection 15j may be rounded.

[0064] Next, an example of how to use the drawing material container cartridge 10 will be described. Hereinafter, a procedure for removing the drawing material container cartridge 10 from the container body 3 of the drawing material container 1 that has run out of the drawing material M and then attaching a new drawing material container cartridge 10 to the container body 3 will be described. Figure 8 (a) and Figure 8As shown in (b), the new drawing material container barrel 10 has a barrel body 11, a threaded barrel 12, a movable body 13 and a barrel cover 15, and the first locking portion 11s of the barrel body 11 is locked to the second locking portion 15g of the barrel cover 15. Specifically, when the barrel portion 11b is inserted into the barrel cover 15, the step 11t of the first locking portion 11s is locked on the annular protrusion 15j of the second locking portion 15g.

[0065] First, the barrel body 11, the threaded barrel 12, and the moving body 13 are removed from the container body 3 of the drawing material container 1 that has run out of the drawing material M. Figure 2 In the state shown, the cap 2 is removed from the container body 3 (inner tube 4), and the engaging portion 12b is moved forward relative to the second convex portion 5c by pulling the barrel body 11 forward. At this time, the barrel body 11 and the threaded barrel 12 move forward relative to the container body 3, and the barrel body 11, the threaded barrel 12 and the moving body 13 are removed from the container body 3.

[0066] Then, the cartridge cap 15 is removed from the cartridge body 11 of the new drawing material container cartridge 10, and the threaded barrel 12 and the cartridge body 11 of the new drawing material container cartridge 10 are inserted backward into the inner side of the inner cylinder 4. When the threaded barrel 12 and the cartridge body 11 are inserted backward into the inner cylinder 4, the engaging portion 12b of the threaded barrel 12 engages with the second convex portion 5c of the outer cylinder 5, and the first engaging portion 11s is engaged with the container body 3 in the axial direction D1. For example, the step 11t of the first engaging portion 11s abuts against the front end of the inner cylinder 4. Thus, the drawing material container 1 becomes usable.

[0067] The drawing material container 1 can be used by rotating the container body 3 relative to the barrel body 11 with the cap 2 removed. If the container body 3 is rotated relative to the barrel body 11 in one direction, the threaded barrel 12 that rotates synchronously with the container body 3 (outer barrel 5) rotates relative to the barrel body 11 and the moving body 13 in one direction, and the screwing action of the internal thread 12k and the external thread 13m is exerted to move the moving body 13 forward relative to the threaded barrel 12. If the moving body 13 moves forward relative to the threaded barrel 12, the drawing material M held in the drawing material holding portion 13b of the moving body 13 is delivered from the opening 11c of the barrel body 11, and the drawing material M is applied to the application portion such as the skin.

[0068] After the drawing material M is applied, if the container body 3 is rotated relative to the barrel body 11 in the direction opposite to the above-mentioned one direction, the container body 3 and the threaded barrel 12 are rotated relative to the barrel body 11 and the moving body 13 in the opposite direction, and the screwing action of the internal thread 12k and the external thread 13m is exerted, so that the moving body 13 moves backward relative to the threaded barrel 12. If the moving body 13 moves backward relative to the threaded barrel 12, the drawing material M is hidden in the opening 11c. Then, the cap 2 is mounted on the container body 3 (inner barrel 4), and the use of the drawing material container 1 is terminated.

[0069] Next, the effects of the drawing material container cartridge 10 according to this embodiment will be described. Figure 2 as well as Figure 8 As shown in (b), the drawing material container cartridge 10 includes a cartridge body 11 and a cartridge cover 15 mounted on the cartridge body 11. The cartridge body 11 includes a barrel portion 11b for storing the drawing material M, and the barrel portion 11b is inserted into the cartridge cover 15 along the axial direction D1. The cartridge body 11 is mounted on the container body 3 by being inserted into the container body 3. The cartridge body 11 includes a first locking portion 11s, and the first locking portion 11s is locked to the container body 3 in the axial direction D1. The cartridge cover 15 includes a second locking portion 15g, and the second locking portion 15g is locked to the first locking portion 11s of the cartridge body 11 in the axial direction D1. Therefore, the first locking portion 11s of the cartridge body 11 is a portion that is locked to the container body 3, and is also a portion that is locked by the second locking portion 15g of the cartridge cover 15. Therefore, the first locking portion 11 s of the cartridge body 11 can be commonly used as a portion locked to the container body 3 and a portion locked to the cartridge cap 15 .

[0070] That is, since the portion locked to the container body 3 and the portion locked to the barrel cap 15 are formed as the first locking portion 11s, the structure of the barrel body 11 can be simplified. By using the first locking portion 11s as the portion locked to the container body 3 and the portion locked to the barrel cap 15, the concave and convex parts of the barrel body 11 can be reduced, so the aesthetics of the barrel body 11 can be improved.

[0071] In the present embodiment, the barrel body 11 has an insertion portion 11q inserted into the container body 3. The first locking portion 11s may be a step 11t whose diameter is enlarged from the insertion portion 11q, and the step 11t may contact the container body 3 when the barrel body 11 is mounted on the container body 3. In this case, by locking the barrel cover 15 on the step 11t, the barrel cover 15 can be more reliably mounted on the barrel body 11. By making the first locking portion 11s a step 11t, the structure of the first locking portion 11s can be simplified, which is conducive to further simplification of the structure.

[0072] In this embodiment, the barrel portion 11b has an inclined surface 11r, which is inclined relative to the axial direction D1 in such a manner that the diameter of the barrel portion 11b increases as the distance from the opening 11c through which the drawing material M is exposed increases along the axial direction D1. In this case, the diameter of the inclined surface 11r of the barrel body 11 inserted into the barrel cover 15 decreases toward the opening 11c. Therefore, the barrel body 11 can be easily inserted into the barrel cover 15.

[0073] In the present embodiment, the cartridge cover 15 has an inner surface 15b extending along the axial direction D1, a bottom 15c located at one end of the inner surface 15b in the axial direction D1, and a contact suppressing portion 15d formed on the inner surface 15b and suppressing contact between the barrel 11b and the bottom 15c. In this case, the contact suppressing portion 15d formed on the inner surface 15b of the cartridge cover 15 suppresses contact between the barrel 11b storing the drawing material M and the bottom 15c. Therefore, the contact between the drawing material M and the inner surface of the cartridge cover 15 can be suppressed.

[0074] The drawing material container kit according to the present invention comprises the drawing material container cartridge 10 and a container body 3, wherein the cartridge body 11 of the drawing material container cartridge 10 is detachably mounted on the container body 3. For example, the drawing material container kit is a drawing material container kit in which the drawing material container cartridge 10 and the container body 3 are packaged and sold as a whole, wherein the drawing material container cartridge 10 is equipped with a cartridge cover 15 as a temporary cover, and the container body 3 constitutes the drawing material container 1 when the cartridge body 11, the threaded cylinder 12, and the moving body 13 are installed. In the drawing material container kit, the cartridge body 11 of the drawing material container cartridge 10 is detachably mounted on the container body 3. Therefore, similarly to the drawing material container cartridge 10, the structure can be made simple and the appearance can be good.

[0075] The above is a description of the embodiments of the drawing material container cartridge and the drawing material container kit according to the present invention. However, the drawing material container cartridge and the drawing material container kit according to the present invention are not limited to the above embodiments, and can be appropriately modified within the scope of the subject matter described in the claims. That is, the shape, size, material, quantity and arrangement of each part of the drawing material container cartridge and the drawing material container kit according to the present invention can be appropriately changed within the scope of the above subject matter.

[0076] For example, the drawing material container kit can be a combination of a drawing material container barrel 10 and a container body 3 without a barrel body 11, a threaded barrel 12 and a movable body 13 installed, or it can be a combination of a drawing material container barrel 10 and a container body 3 (drawing material container 1) with a barrel body 11, a threaded barrel 12 and a movable body 13 installed.

[0077] In the above embodiment, the drawing material container cartridge 10 having the cartridge body 11 having the first locking portion 11s as a step 11t is described. However, the first locking portion may not be a step 11t, for example, it may be a convex portion protruding in the radial direction, or it may be a concave portion recessed in the radial direction. As such, the shape of the first locking portion may be appropriately changed. The shape of the second locking portion of the cartridge cover may also be appropriately changed.

[0078] In the above embodiment, the drawing material container barrel 10 is described, and the drawing material container barrel 10 has a threaded barrel 12 with an internal thread 12k and a movable body 13 with an external thread 13m, and has the following functions: the threaded barrel 12 and the movable body 13 rotate relative to each other, and the screwing action of the internal thread 12k and the external thread 13m is exerted to deliver the drawing material M. However, the drawing material container barrel may not have the threaded barrel 12 and the movable body 13. The drawing material container barrel may not be a structure that delivers the drawing material by relative rotation. The drawing material container barrel may have a delivery mechanism that is a mechanical push-out mechanism such as a knock type instead of relative rotation, and the drawing material is pushed out by the delivery mechanism, or it may have a squeeze type delivery mechanism.

[0079] In the above embodiment, the drawing material container barrel 10 having the drawing material M as a cosmetic material is described. However, the drawing material may also be an item other than a cosmetic material. For example, the drawing material may be a core material used in writing tools such as crayons. Thus, the drawing material container barrel and the drawing material container kit according to the present invention are not limited to cosmetic materials, and can be applied to containers having various drawing materials such as writing tools or stationery.
