Description

[Technical Field]

[0001] The present invention relates to an art supply case for storing solid drawing supplies such as crayons, oil pastels, conte, etc. The art supply case of the present invention is suitable for use when selling crayons and the like as a set. [Background technology]

[0002] Crayons and oil pastels are suitable as drawing materials for young children and schoolchildren because they can be held in the hand and used to draw. Solid drawing materials with a structure and usage similar to crayons include pastels, Conte, Cray-Pas (a registered trademark of Sakura Color Products Co., Ltd.), colored chalk, and stick paints. The crayons and other items mentioned above are often sold in sets of multiple different colors, such as a 6-color set or a 12-color set. Furthermore, when crayons and other items are sold as a set, they are often sold in an art supply case made of paper or plastic. That is, solid drawing materials such as crayons are sold as a set in a state where they are arranged side by side in an art supply case. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Jikko No. 12105, Showa 32 [Patent Document 2] Jikko No. 1707, Showa 27 [Patent Document 3] Jikko No. 12-18961 [Patent Document 4] Jikko No. 12-10320 [Patent Document 5] Jikko No. 13715, Showa 33 Summary of the Invention [Problem to be solved by the invention]

[0004] Solid art materials generally have low rigidity. Solid art materials for infants are particularly soft. In other words, since infants have little strength, solid art materials for infants are often formulated to be soft so that they can be applied to paper with little pressure. For this reason, if solid art materials collide with each other during transport, they may break. To solve this problem, it is desirable that the art supply case be capable of holding the solid art supplies so that they do not move.

[0005] On the other hand, if the solid drawing material is held immovably in the art supply case, there is a problem that it is difficult to remove the solid drawing material when it is to be used. Furthermore, because solid drawing materials are held directly in the hand to draw pictures, they are covered with a wrapping paper or resin sheet to prevent the hands from getting dirty. That is, solid drawing materials are, for example, cylindrical, and the peripheral portion is held directly in the hand, and the tip is pressed against paper or the like and rubbed. For this reason, wrapping paper or the like is attached to the peripheral side to prevent the hands from getting dirty. On the other hand, because solid drawing materials are applied by pressing the tip directly against paper or the like, there is no wrapping paper near the tip, and the main body is exposed.

[0006] Therefore, when removing the solid art material from the art supply case, the user should remove it by pinching the area where the paper wrapper is wrapped with his or her hand so as not to get his or her hands dirty. However, the majority of users of solid art supplies are young children and elementary school children who lack knowledge and experience, and therefore tend to pick out the exposed part of the solid art supply without the paper wrapper when removing it from the art supply case. SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide an art supplies case that has a function that encourages the user to pinch the portion where the wrapping paper is wrapped when removing solid art supplies. [Means for solving the problem]

[0007] An embodiment for solving the above-mentioned problems is an art supplies case for storing rod-shaped solid drawing materials with a coating on the periphery, the art supplies case having a main body member, in which compartments in which the solid drawing materials are attached are arranged in parallel, the compartments being surrounded by an inner wall that is close to or in contact with the solid drawing materials, and the inner wall is missing a portion corresponding to the longitudinal center of the solid drawing material, so that the inner wall is connected to the center of an adjacent compartment.

[0008] The art supply case of this embodiment has a main body member, and compartments in which solid art materials are placed are arranged side by side in the main body member. The compartments are surrounded by inner walls that are close to or in contact with the solid art materials. Therefore, the solid art materials are substantially fixed within the main body member, and the solid art materials do not collide with each other during transport. Therefore, when using the art supply case of this embodiment, the solid art materials are less likely to be damaged during transport. Furthermore, in this type of art supply case, the compartments are surrounded by inner walls that are close to or in contact with the solid drawing material, and the inner walls are missing a section that corresponds to the longitudinal center of the solid drawing material and are connected to the center of the adjacent compartment, so there is a gap in the section that corresponds to the longitudinal center of the solid drawing material. Therefore, when users want to take out the solid art material, they have an impulse to insert their fingers into the gap and pick up the solid art material. In other words, even young children will get the idea that they can take out the solid art material by inserting their fingers into the wide gap, and will pick up the middle part where the wrapping paper is wrapped and take out the solid art material.

[0009] In the above-mentioned aspect, it is desirable that there is a partition wall separating adjacent compartments, one side of the partition wall forming the inner wall of one compartment and the other side of the partition wall forming the inner wall of the adjacent compartment, and that the longitudinal center of the partition wall is missing so that it is connected to the center of the adjacent compartment.

[0010] In this art supply case, there is a partition wall separating adjacent compartments, and the partition wall is missing a central portion in the longitudinal direction, so that the central portion of the adjacent compartment is connected to the central portion of the adjacent compartment, and therefore there is a relatively wide gap between the middle portions of the solid art supplies stored adjacently. Therefore, when removing the solid drawing material, the user can insert a finger into the gap and pick up the solid drawing material.

[0011] In each of the above-mentioned embodiments, it is desirable that there is an outer wall that forms the peripheral wall of the main body member, one side of the outer wall forms the inner wall of one compartment, the outer wall is missing a portion corresponding to the center of the solid drawing material, and the outermost compartment is connected to the outside of the main body member.

[0012] According to this aspect, gaps are formed on both sides of the solid drawing material arranged at the outermost position, so that the solid drawing material can be easily picked up and removed.

[0013] In each of the above-mentioned embodiments, when a solid drawing material is stored in the compartment, it is desirable that the gap in the longitudinal direction is 2 mm to 0 mm, and the gap in the width direction is 2 mm to 0 mm.

[0014] According to this embodiment, there is little space around the solid drawing material except for the missing portion of the inner wall, which encourages the user to insert their fingers into the missing portion and pick it out.

[0015] In each of the above-mentioned embodiments, it is desirable that inner walls exist on the surfaces corresponding to the end faces and peripheral surfaces near both ends of the solid drawing material.

[0016] According to this aspect, the solid drawing material is less likely to move within the main body member, and is less likely to be damaged during transportation.

[0017] In each of the above-mentioned aspects, it is desirable that a convex portion be formed in the center of the bottom of the compartment in the longitudinal direction, and that the convex portion be provided with a groove for holding the solid drawing material.

[0018] According to this aspect, a solid drawing material can be held.

[0019] In each of the above-described aspects, it is desirable that there is an outer box that houses the main body member, that there is a marking on the bottom of the outer box or between the outer box and the main body member that indicates the color of the solid drawing material, that the main body member is transparent, and that the marking can be seen from above the main body member.

[0020] According to this aspect, when returning the solid drawing material to the main body member, it is possible to know the compartment in which the solid drawing material should be placed.

[0021] An embodiment of the art supply set is characterized in that solid art supplies are stored in the compartments of the art supply case.

[0022] The covering is preferably a wrapping paper, and the main body of the solid drawing material is preferably exposed near the tip of the solid drawing material. [Effects of the Invention]

[0023] According to the art supply case of the present invention, when removing solid art supplies, the portion wrapped with paper is easy to grasp and your hands are less likely to get dirty. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0025] Hereinafter, an embodiment of the present invention will be described. The art supply set 1 of this embodiment includes an art supply case 2 and a solid art supply 3 stored therein. The solid drawing material 3 here is an oil pastel, which is a mixture of wax, pigment, and filler, molded into a rod shape. The solid drawing material 3 used in this embodiment is a short, cylindrical rod. The solid drawing material 3 used in this embodiment is intended for small children and is thicker than regular oil pastels.

[0026] The solid drawing material 3 has a wrapping paper 5 covering the periphery of its main body. 1 and 2, the wrapping paper 5 is provided around the entire circumference except for the tip region in the longitudinal direction. The wrapping paper 5 is wound around at least the central region in the longitudinal direction. In FIG. 4, the wrapping paper 5 is shown shaded. In this embodiment, there are black solid drawing materials 3a, blue solid drawing materials 3b, green solid drawing materials 3c, yellow solid drawing materials 3d, light orange solid drawing materials 3e, and red solid drawing materials 3f.

[0027] 2, the art supply case 2 is composed of a main body member 10 and an outer box 11. The outer box 11 is composed of a lower box and a lid, but the lid is not shown in the drawings. The main body member 10 is formed by vacuum molding a resin sheet to form projections and recesses, and is thin in all areas as shown in Figures 4(a) and 5. The main body member 10 is transparent. The main body member 10 has an outer wall 16 that constitutes the peripheral wall 15. Inside the outer wall 16, there are a dividing wall 18 and a partition wall 22, which divide the main body member 10 into six compartments 25. The compartments 25 are recesses in which the solid drawing material 3 is accommodated.

[0028] Since the art supply case 2 is made by vacuum molding, the outer wall 16, the partition wall 18, and the partition wall 22 are hollow as shown in FIG. 5. However, the width Wa of the outer wall 16 and the width Wa of the partition wall 22 are The overall width Wb is approximately 3 mm to 15 mm, which is the same as the width of a child's finger. More preferably, it is approximately 5 mm to 12 mm. The thicknesses of the outer wall 16 and the partition wall 22 are measured at the center of each wall in the height direction. Each section 25 is a concave portion 17 formed by vacuum molding. Six concave portions 17 are provided in the main body member 10 of this embodiment.

[0029] That is, the inside of the main body member 10 is divided into an upper region 20 and a lower region 21 by a dividing wall 18, and three recessed portions 17 are provided in each region, arranged side by side. That is, two partition walls 22 are provided in each of the upper region 20 and the lower region 21, and the partition walls 22 divide the upper region 20 and the lower region 21 into three compartments 25. Therefore, in this embodiment, the main body member 10 is divided into six compartments 25. That is, the compartments 25 are arranged in parallel, separated by the partition walls 22.

[0030] Each compartment 25 is a rectangular recess in plan view, into which the solid drawing material 3 fits. That is, the size of the compartment 25 is approximately the same as that of a new solid drawing material 3. That is, as shown in FIG. 5(b), the effective depth of the compartment 25 corresponds to the diameter of the solid drawing material 3. That is, as will be described later, there is a protrusion 55 at the bottom of each compartment 25, and when the protrusion 55 is taken as the effective bottom surface of the compartment 25, the depth corresponds to the diameter of the solid drawing material 3. 1, 6, and 7, the overall length of the section 25 corresponds to the overall length of the solid drawing material 3. The width of the section 25 corresponds to the width (diameter) of the solid drawing material 3. Because the inner walls 50, 51 of the compartment 25 are inclined due to the need for a draft angle, the length and width of the compartment 25 vary depending on the position in the height direction, but when the solid drawing material 3 is stored, the gap with the solid drawing material 3 is 2 mm to 0 mm at the height of the center of the solid drawing material 3. More preferably, when the solid drawing material 3 is stored in the compartment 25, the gap in the longitudinal direction is 0.5 mm or less, and the gap in the width direction is also 0.5 mm or less. Most preferably, the gap in the longitudinal direction is about 0.2 mm, and the gap in the width direction is also about 0.2 mm.

[0031] In this embodiment, the first section 25a, the second section 25b, and the third section 25c are all located in the upper region 20, and their longitudinal ends are surrounded by the upper short side 40 of the outer wall 16 in the drawing and the dividing wall 18. The side of the first compartment 25a is surrounded by the long side 41 on the left side of the outer wall 16 in the drawing and the first partition wall 22a. The side of the second compartment 25b is surrounded by the first partition wall 22a and the second partition wall 22b. The side of the third compartment 25c is surrounded by the long side 43 on the right side of the outer wall 16 in the drawing and the second partition wall 22b. The fourth section 25d, the fifth section 25e, and the sixth section 25f are all located in the lower region 21, and their longitudinal ends are surrounded by the partition wall 18 and the lower short side 42 of the outer wall 16 in the drawing. The side of the fourth compartment 25d is surrounded by the long side 41 on the left side of the outer wall 16 in the drawing and the third partition wall 22c. The side of the fifth compartment 25e is surrounded by the third partition wall 22c and the fourth partition wall 22d. The side of the sixth compartment 25f is surrounded by the long side 43 on the right side of the outer wall 16 in the drawing and the fourth partition wall 22d.

[0032] Each compartment 25 has an inner wall 50 on the side surface thereof formed by the side surface of the outer wall 16 or the side surface of the partition wall 22 . That is, the first section 25a, the third section 25c, the fourth section 25d, and the sixth section 25f arranged on the outside have the long sides 41, 43 of the outer wall 16 as inner walls 50 extending in one longitudinal direction. In addition, in the first section 25a, the third section 25c, the fourth section 25d, the fifth section 25e, and the sixth section 25f, one side surface of the partition wall 22 becomes the inner wall 50 of the other side surface extending in the longitudinal direction.

[0033] In the second section 25b and the fifth section 25e disposed between them, both side surfaces of the partition wall 22 serve as inner side walls 50. Thus, in this embodiment, there is a partition wall 22 that separates adjacent compartments 25, and one side of the partition wall 22 forms the inner wall 50 of the side of one compartment 25, and the other side of the partition wall 22 forms the inner wall 50 of the side of the adjacent compartment 25. In this embodiment, the main body member 10 has an outer wall 16 that forms a peripheral wall thereof, and one of the long sides 41 and 43 of the outer wall 16 defines an inner wall 50 of one of the compartments 25. It is composed of: The side surfaces of the short sides 40 and 42 of the outer wall 16 and the side surfaces of the partition wall 18 form inner walls 51 on the end faces of each compartment 25 .

[0034] In the main body member 10 of this embodiment, each partition wall 22 has a cutout 30, and adjacent compartments 25 are connected at the center by the cutout 30. The first compartment 25a, third compartment 25c, fourth compartment 25d, fifth compartment 25e, and sixth compartment 25f, which are arranged on the outside, are connected to the outside by a cutout 31 provided in the outer wall 16. That is, in the main body member 10 of this embodiment, each compartment 25 is surrounded by inner walls 50, 51, but the inner walls 50 on the side are missing a portion corresponding to the center of the solid drawing material in the longitudinal direction, and communicate with the center of the adjacent compartment 25. The missing portions of the inner walls 50 are connected by a joining wall 53.

[0035] The notches 30 and 31 are both formed in the central region in the longitudinal direction of the compartment 25. Therefore, both ends of the compartment 25 in the longitudinal direction are covered on three sides as shown in Figures 1, 2, 3, 6, and 7. That is, the end faces of the compartment 25 are closed by the side faces of the short sides 40 and 42 of the outer wall 16 and the side faces of the dividing wall 18 or the outer wall 16 as shown in Figure 7(c). The vicinity of the end of the compartment 25 is closed on three sides by the side faces of the long sides 41 and 43 of the outer wall 16 or the side faces of the partition wall 22.

[0036] In contrast, the middle part of the compartment 25 has no wall to close it off. That is, each compartment 25 is surrounded by inner walls 50, 51, but has a central portion missing in the longitudinal direction, so that the compartment 25 communicates with the central portion of the adjacent compartment 25. In this embodiment, the cutouts 30, 31 provided in the upper region 20 have the same length and are positioned relative to the section 25. The cutouts 30, 31 provided in the lower region 21 also have the same length and are positioned relative to the section 25. A solid drawing material 3 is attached to each compartment 25, and the notches 30, 31 provided in each compartment 25 correspond to the center of the solid drawing material 3 in the longitudinal direction, and correspond to the area covered with the wrapping paper 5.

[0037] A convex portion 55 is provided at the bottom of each compartment 25. The convex portion 55 is located at a position corresponding to the missing portions 30, 31. That is, the bottom of each compartment 25 is convex, with the center being higher and both ends being lower. The surface of the convex portion 55 of each compartment 25 has an arc-shaped depression 66, as shown in Figure 5(a). That is, the bottom of each compartment 25 has a groove-like depression 66 extending in the longitudinal direction, and the cross-sectional shape of the depression 66 is arc-shaped.

[0038] Next, the outer box 11 will be described. The outer box 11 is a low box having a rectangular planar shape and a lid, the lid being omitted from the drawing. The outer box 11 has a bottom 60 and side walls extending from each side of the bottom. As shown in Figures 2 and 6(a), the bottom surface of the outer box 11 is marked with indications indicating the colors of the solid drawing materials 3. Since the art supply set 1 of this embodiment accommodates six bottles of the solid drawing materials 3, the bottom 60 of the outer box 11 is provided with indications 61 in six locations accordingly. The display of the mark 61 is composed of a color 62 and letters 63 indicating the color name. The color 62 is a certain area colored the same color as the solid drawing material 3 to be applied. The letters 63 are written in Japanese. The letters may also be in other languages.

[0039] The art supplies case 2 is constructed by inserting a main body member 10 into a lower box of an outer box 11. When the main body member 10 is attached to the outer box 11, each compartment 25 of the main body member 10 overlaps directly above the indicia 61. As described above, the main body member 10 is transparent and has a thin wall, so when the art supplies case 2 is viewed from above the main body member 10, as shown in Figure 6(b), the indicia 61 attached to the outer box 11 can be seen through the main body member 10. In other words, the indicia 61 representing the color can be seen from above the main body member 10.

[0040] The art supply set 1 contains solid drawing materials 3 in an art supply case 2. The solid drawing materials 3 are attached to the compartments 25 of the main body member 10. The solid drawing materials 3 are housed in the positions of the colors indicated by the display 61. The black solid drawing material 3a is contained in the section 25a where the black marking 61 is visible, the blue solid drawing material 3b is contained in the section 25b where the blue marking 61 is visible, and the green solid drawing material 3c is contained in the section 25c where the green marking 61 is visible. The yellow solid drawing material 3d is contained in the section 25d where the yellow marking 61 is visible, the light orange solid drawing material 3e is contained in the section 25e where the light orange marking 61 is visible, and the red solid drawing material 3f is contained in the section 25f where the red marking 61 is visible.

[0041] As described above, the depth, length, and width of the compartment 25 are approximately the same as the diameter and overall length of the solid drawing material 3 in a new state, so the solid drawing material 3 fits snugly into the compartment 25. Therefore, there is almost no gap around the solid drawing material 3 except for the missing portions 30 and 31.

[0042] Seeing this state, even an inexperienced child would normally try to insert their fingers into the gap formed by the cutouts 30 and 31 as shown in Figure 3(b) and pick it out. That is, the width Wa of the outer wall 16 and the width Wb of the partition wall 22 are both approximately 3 mm to 15 mm overall, which is the same as the width of a child's finger. Therefore, the cutouts 30 and 31 leave gaps around the solid drawing material 3 large enough for a child's fingers to fit through. Children are naturally inclined to insert their fingers into such gaps.

[0043] Furthermore, in reality, the solid drawing material 3 is tightly fitted into the compartment 25, and it is difficult to remove the solid drawing material 3 by any other means, so after trial and error, the child will insert his or her fingers into the gap formed by the notches 30 and 31 and pick it out. In other words, the child learns through his or her own experience how to insert his or her fingers into the gap formed by the notches 30 and 31 and pick out the solid drawing material 3. In this embodiment, the missing portions 30, 31 are located in the center of the compartment 25, and the wrapping paper 5 of the solid drawing material 3 is located in the missing portions 30, 31. Therefore, an infant will inevitably pinch the wrapping paper 5 to remove the solid drawing material 3. This prevents the infant's hands from getting dirty.

[0044] Furthermore, a convex portion 55 is provided at the bottom of each compartment 25 of the main body member 10, making it elevated, so that when one end of the solid drawing material 3 is pushed down, the solid drawing material 3 tilts and the other end tends to lift up, but in a new state, the solid drawing material 3 fits snugly into the compartment 25, so the solid drawing material 3 is less likely to tilt and the other end does not lift up. When the solid drawing material 3 becomes shorter, the other end can be lifted up by pushing in one end of the solid drawing material 3.

[0045] In the embodiment described above, the shape of the solid drawing material 3 is a thick cylindrical rod, but the shape of the solid drawing material 3 is not limited to this. For example, it may be a thin rod-shaped material like a regular crayon, or it may be a rod with a square cross section like Conte.

[0046] The number of items stored in the art supplies case 2 is arbitrary, and may be less than six or more than six. Although the main body member 10 in the above-described embodiment is manufactured by vacuum forming, the manufacturing method is not limited thereto. The main body member 10 described above is a hollow structure because it is a vacuum formed product, but it may also be a solid structure manufactured by other manufacturing methods.
