[Assembly structure of reel package 10]
The reel package 10 in FIG. 1 is assembled from a molded resin molded body. Next, the assembly structure of the reel package 10 will be described.

  FIG. 5 is an exploded view showing the reel package in FIG. FIG. 6 is a side view showing the reel package as seen from the direction indicated by arrow VI in FIG. FIG. 7 is a cross-sectional view showing the reel package along the line VII-VII in FIG.

  With reference to FIGS. 5 to 7, the reel package 10 in the present embodiment is assembled from a resin molded body 15. When the resin molded body 15 is viewed in plan, the side portion 30, the side portion 20, and the side portion 40 are molded into the resin molded body 15 so as to be aligned in one direction in the order given. The resin molded body 15 has a substantially rectangular shape in which the arrangement direction of the side portions 20, 30, 40 matches the longitudinal direction, and the direction orthogonal to the arrangement direction of the side portions 20, 30, 40 matches the short direction. It has a plan view.

  A bent portion 51 is formed in the resin molded body 15 between the side portion 20 and the side portion 30. A bent part 52 is formed in the resin molded body 15 between the side part 20 and the side part 40. The bent part 51 and the bent part 52 extend in parallel to each other along the short side direction of the resin molded body 15 in a substantially rectangular plan view. The bending part 51 and the bending part 52 have a cross section extending in an arc shape when cut by a plane orthogonal to the extending direction. With such a configuration, the resin molded body 15 is formed so that it can be bent at each of the bent portion 51 and the bent portion 52.

  The shapes of the bent part 51 and the bent part 52 are not particularly limited as long as the resin molded body 15 can be bent repeatedly.

  The side part 20, the side part 30, and the side part 40 further have a plane part 32, a plane part 22, and a plane part 42, respectively, as constituent parts of each side part.

  When the resin molded body 15 is viewed in plan, the flat portion 32 is disposed between the support portion 31 and the bent portion 51, and the flat portion 22 is disposed between the support portion 21 and the bent portion 51. . Further, the flat portion 22 is disposed between the support portion 21 and the bent portion 52, and the flat portion 42 is disposed between the support portion 41 and the bent portion 52.

  FIG. 8 is an enlarged cross-sectional view of a range surrounded by a two-dot chain line VIII in FIG. FIG. 9 is an assembly view of the reel package shown in FIG.

  The resin molded body 15 has a symmetrical shape with respect to the center in the arrangement direction of the side portion 30, the side portion 20, and the side portion 40. Hereinafter, the structure of the bent positions of the side portion 20 and the side portion 30 shown in FIG. 6 to FIG. 9 will be described as representative, but the bent position of the side portion 20 and the side portion 40 shown in FIG. Have

  With reference to FIGS. 6 to 9, the flat portion 32 is formed by bending from the end portion of the support portion 31 in the circumferential direction of the curved surface 31 a and extending toward the bent portion 51. The flat surface portion 32 is formed to extend in a flat shape between the end portion of the support portion 31 and the bent portion 51. The flat surface portion 22 is bent from the end portion of the support portion 21 in the circumferential direction of the curved surface 21 a and extends toward the bending portion 51. The flat surface portion 22 is formed to extend in a flat shape between the end portion of the support portion 21 and the bent portion 51.

  The flat portion 32 and the flat portion 22 are formed adjacent to the bent portion 51. The flat portion 32 is formed to extend in a substantially radial direction of the curved surface 31a extending in the circumferential direction. The flat portion 22 is formed so as to extend in a substantially radial direction of the curved surface 21a extending in the circumferential direction. In a state where the reel package 10 is unfolded (the state shown in FIG. 8), the plane portion 32 and the plane portion 22 intersect at an angle of approximately 90 ° at the bent portion 51.

  The flat portion 32 has a surface 32a and a surface 32b facing the opposite side of the surface 32a. The flat portion 22 further has a surface 22a and a surface 22b facing the opposite side of the surface 22a. The surface 32a and the surface 22a are disposed on the accommodation space 50 side in a state where the reel package 10 is assembled (a state shown in FIG. 9). The surface 32b and the surface 22b are disposed in a space outside the accommodation space 50 in a state where the reel package 10 is assembled. In a state where the reel package 10 is unfolded, the surface 32a and the surface 22a are arranged to face each other.

  The shape of the reel package 10 in which the side portion 30 rises from the end portion of the side portion 20 is obtained by bending the resin molded body 15 at the bending portion 51. At this time, the plane portion 32 and the plane portion 22 are overlapped with each other, and the curved surface 31a is disposed at a position extending continuously from the curved surface 21a. The plane part 32 and the plane part 22 are overlapped with each other, whereby the angle at which the side part 20 and the side part 30 intersect is determined.

  In the reel package 10 in the present embodiment, a convex portion 61 and a concave portion 66 are formed on the resin molded body 15. The convex portion 61 is formed so as to protrude from the surface of the side portion 30 disposed on the accommodation space 50 side, more specifically, from the surface 32 a of the flat portion 32. The recess 66 is formed so as to be recessed from the surface of the side portion 20 arranged on the accommodation space 50 side, more specifically, from the surface 22 a of the flat portion 22.

  The convex portion 61 and the concave portion 66 are respectively disposed adjacent to the bent portion 51. The convex portion 61 and the concave portion 66 are formed in a line in a direction orthogonal to the extending direction of the bent portion 51. The convex portion 61 and the concave portion 66 are formed at positions where the distances from the bent portion 51 are substantially equal. In the present embodiment, two sets of convex portions 61 and concave portions 66 are formed at a distance in the extending direction of the bent portion 51.

  The resin molded body 15 may be formed with one set of convex portions 61 and concave portions 66, or may be formed with three or more sets of convex portions 61 and concave portions 66.

  With such a configuration, when the resin molded body 15 is bent at the bending portion 51 and the flat portion 32 and the flat portion 22 are overlapped with each other, the convex portion 61 is automatically fitted into the concave portion 66. Similarly, when the resin molded body 15 is bent at the bending portion 52 in FIG. 5 and the flat portion 42 and the flat portion 22 are overlapped with each other, the convex portion 61 formed on the flat portion 42 is formed on the flat portion 22. The recess 66 is automatically fitted. Thereby, the side part 20 and the side part 30 and the side part 40 rising from both ends of the side part 20 are fixed, and the resin molded body 15 is assembled to the reel package 10 in FIG.

  As described above, according to the reel package 10 in the present embodiment, the assembly of the reel package 10 can be completed with one action of bending the resin molded body 15 at the bent portion 51 and the bent portion 52.

  In the present embodiment, the convex portions 61 formed on the side portion 30 and the side portion 40 have shapes recessed from the flat portion 32 and the flat portion 42 as viewed from the space outside the accommodation space 50, respectively. For this reason, when assembling the reel package 10, the operator inserts a finger into the concave portion 63 (see FIG. 8) formed by the convex portion 61, and as shown by an arrow 104, The resin molded body 15 may be bent at the bent portion 51 and the bent portion 52 so that the side portion 30 and the side portion 40 are lifted from both ends. Thereby, the convex part 61 can be easily fitted to the concave part 66 with the bent part 51 and the bent part 52 as fulcrums.

  In the present embodiment, the convex portion 61 and the concave portion 66 are provided at the corner portions of the side portion 20, the side portion 30, and the side portion 40. Since this corner portion becomes an empty space when the disc-shaped reel 200 is accommodated, a structure for fixing the side portion 20, the side portion 30, and the side portion 40 can be provided by effectively using the space. .

  FIG. 10 is a cross-sectional view showing the resin molded body along the line XX in FIG. With reference to FIG. 10, the structure of the convex part 61 and the recessed part 66 which are shape | molded by the resin molding 15 is demonstrated still in detail.

  The recess 66 forms an opening surface 67 on the surface 22 a of the flat portion 22. The convex portion 61 has a protruding end 62 at the tip that protrudes from the surface 32 a of the flat portion 32. The recess 66 is formed such that the opening width B1 in the extending direction of the bent portion 51 (the direction indicated by the arrow 102 in FIG. 10) is substantially constant regardless of the depth from the opening surface 67. The convex portion 61 has a width B2 larger than the opening width B1 of the concave portion 66 at a position between the surface 32a of the flat portion 32 and the protruding end 62. The convex portion 61 has a tapered portion 64 formed so that the width gradually decreases from the position having the width B2 toward the protruding end 62. The convex portion 61 has a width B3 that is smaller than the opening width B1 at the protruding end 62.

  In the reel package 10 assembled from the molded resin molded body 15, the molded recess 66 further recessed from the flat surface portion 22 is formed with a reduced thickness. On the other hand, the convex portion 61 formed by projecting the flat portion 32 is similarly formed with a small thickness, but the bent portion 103 where the inclination of the tapered portion 64 starts is convex in a rib shape. The rigidity of the portion 61 is increased. Further, as shown in FIGS. 5 and 8, a groove 65 is formed in the flat portion 32 for the purpose of increasing the rigidity of the convex portion 61. The groove 65 is formed so as to be recessed from the surface 32 a and extend linearly along the boundary between the flat surface portion 32 and the convex portion 61. With such a configuration, the convex portion 61 is formed to have higher rigidity than the concave portion 66.

  In the assembly process of the reel package 10 in the present embodiment, the convex portion 61 is fitted into the concave portion 66 while the thin concave portion 66 is expanded by the highly rigid convex portion 61. As a result, the press-fit structure of the convex part 61 with respect to the concave part 66 is obtained, and the side part 20 and the side part 30 can be firmly fixed. On the other hand, the tapered portion 64 formed in a tapered shape is an introduction portion when the convex portion 61 is fitted into the concave portion 66, and therefore the convex portion 61 is smoothly fitted into the concave portion 66 regardless of the press-fitting structure. Can be combined.

  As the structure in which the convex portion 61 is firmly fitted to the concave portion 66, the convex portion 61 is formed into a shape having a larger width as it approaches the protruding end 62, or the opening width is reduced as the concave portion 66 is closer to the opening surface 67. Then, a method of molding can be considered. However, when such a reverse taper structure is adopted, when a large number of resin molded bodies 15 are stacked, such as when the resin molded bodies 15 are stored or transported, the convex portions 61 or the concave portions 66 are arranged vertically in the stacking direction. It becomes difficult to fit with. On the other hand, in this Embodiment, the stacking property of the resin molding 15 at the time of a storage or conveyance can be made favorable by making the convex part 61 and the recessed part 66 into said press-fit structure.

[Edge structure]
Next, the structure of the edge portions 26, 36, 46 provided on the reel package 10 in the present embodiment will be described in detail.

  FIG. 11 is a cross-sectional view showing the reel package along the line XI-XI in FIG. Referring to FIG. 11, the edge portion 26 is bent from both ends of the support portion 21 and extends toward the inside in the radial direction of the curved surface 21a. Further, the edge portion 26 is bent by approximately 180 ° and extends outward in the radial direction of the curved surface 21a. The edge portion 26 is formed so as to protrude outward in the radial direction of the curved surface 21 a from the support portion 21.

  The edge portion 26 has a distal end portion 27 at the distal end that extends outward in the radial direction of the curved surface 21a. The tip portions 27 extending from both ends of the support portion 21 are formed so as to be disposed on a virtual plane 73a parallel to the central axis 101 in FIG. When viewed from the axial direction of the curved surface 21a, the tip portion 27 is formed to extend in a straight line.

  The edge portion 26 includes a flange portion 105 disposed on the radially inner side of the curved surface 21a with respect to the support portion 21, and a leg portion 106 disposed on the radially outer side of the curved surface 21a with respect to the support portion 21. Yes. The collar portion 105 regulates the position of the reel 200 disposed in the accommodation space 50 in the axial direction of the curved surface 21a. The leg portion 106 is used as a leg that supports the reel package 10.

  FIG. 12 is a perspective view showing a state where the reel package in FIG. 3 is placed in a different posture. Referring to FIGS. 11 and 12, edge 36 and edge 46 have the same structure as edge 26, and each has a tip 37 and a tip 47 corresponding to tip 27. The tip portion 37 is formed to extend in a straight line, and intersects one end of the tip portion 27 at a substantially right angle. The tip portion 47 is formed to extend in a straight line and intersects the other end of the tip portion 27 at a substantially right angle.

  The distal end portion 27 is formed so as to be disposed on the flat surface 73 a together with the bent portion 51 and the bent portion 52. The support portion 21 is formed at a position deeper inward in the radial direction of the curved surface 21 a than the tip portion 27. The tip portion 37 is formed so as to be disposed on the flat surface 73b together with the bent portion 51 and a bent portion 91 described later. The support portion 31 is formed at a position deeper inward in the radial direction of the curved surface 31 a than the distal end portion 37. The distal end portion 47 is formed so as to be disposed on the plane 73c together with the bent portion 52 and a bent portion 91 described later. The support part 41 is formed at a position deeper inward in the radial direction of the curved surface 41 a than the tip part 47.

  According to such a configuration, as shown in FIG. 1, when the reel package 10 is placed so that the opening 56 opens vertically upward, the edge portion 26 is radially outward from the support portion 21. Therefore, the edge 26 can be used as a leg for supporting the package. In addition, as shown in FIG. 12, when the reel package 10 is placed so that the opening 56 opens in the horizontal direction, the edge 36 is formed so as to protrude radially outward from the support portion 31. Therefore, the edge 36 can be used as a leg for supporting the package. Further, when the reel package 10 is placed upside down from the posture shown in FIG. 12, the edge 46 is formed so as to protrude outward in the radial direction from the support portion 41. Can be used as a leg.

  As described above, in the reel package 10 according to the present embodiment, the edge portion 26, the edge portion 36, or the edge portion 46 functions as a package support leg in accordance with the posture in which the package is placed. For this reason, for example, the reel package 10 is accommodated in a separate box in the form shown in FIG. 1 at the time of conveyance, and the reel package 10 is installed on a shelf in the form shown in FIG. Even if the posture of placing the package 10 changes, stable placement is always possible.

  Further, since the support portions 21, 31, and 41 that support the reel 200 are formed at positions deeper inward than the tip portions 27, 37, and 47, the support portions 21, 31, and 41 and the reel package 10 are arranged.

[Reel fall-off prevention structure]
Next, a structure for preventing the reel 200 arranged in the accommodation space 50 from falling off will be described.

  As described above with reference to FIG. 4, the reel 200 is gripped from three directions by the curved surface 31 a, the curved surface 21 a, and the curved surface 41 a extending continuously in the circumferential direction, thereby allowing the reel 200 to move within the accommodation space 50. It is supported. In the present embodiment, the support portions 21, 31, 41 are formed so that the angle α at which the curved surface 31a, the curved surface 21a, and the curved surface 41a are divided by the opening 56 is smaller than 180 °. For example, the angle α satisfies a relationship of 160 ° <α <180 °. The support portion 31 and the support portion 41 form a protruding portion 76 that protrudes in a direction substantially orthogonal to the reel 200 removal direction.

  According to such a configuration, the opening width of the opening 56 is formed to be narrower than the diameter of the reel 200, so that the reel 200 supported in the accommodation space 50 can be prevented from falling outside through the opening 56. .

  On the other hand, as described with reference to FIG. 9, the side portion 20, the side portion 30, and the side portion 40 are fixed to each other by the fitting of the convex portion 61 and the concave portion 66. It is formed with a certain degree of flexibility in the direction of widening the opening width of the opening 56. Therefore, in spite of the structure in which the opening width of the opening 56 is narrower than the diameter of the reel 200, the reel 200 can be easily put in and out by appropriately bending the reel package 10.

  FIG. 13 is a sectional view showing a modification of the reel package shown in FIG. Referring to FIG. 13, in this modification, as compared with the reel package 10 shown in FIG. 1, the side portion 20, the plane portion 22 that determines the angle at which the side portion 30 and the side portion 40 intersect, The inclination angle of the part 32 and the plane part 42 is different. Thereby, the side part 20, the side part 30, and the side part 40 cross | intersect at an angle smaller than 90 degrees, respectively. As a result, the curved surface 31a and the curved surface 41a are arranged on the inner diameter side of the virtual line 111 in which the curved surface 21a is extended in a perfect circle shape.

  According to such a configuration, even if the reel package 10 is slightly bent in the direction in which the opening width of the opening 56 widens, the outer peripheral surface of the reel 200 disposed in the accommodation space 50, the curved surface 31a, and It can suppress that a clearance gap produces between the curved surfaces 41a. As a result, the reel 200 can be more reliably prevented from falling outside through the opening 56.

  In addition, the structure where the curved surface 31a and the curved surface 41a are arrange | positioned rather than the virtual line 111 is obtained by changing the position of the curved surface 31a and the curved surface 41a shape | molded in the resin molding 15 in FIG. May be.

[Reel fall prevention structure]
As an example of the usage pattern of the reel package 10, there is a mode in which the reel package 10 is placed on a shelf of a factory, the reels 200 are taken out from the reel package 10 one by one, and a capacitor is used. The reel package 10 according to the present embodiment is provided with a structure for preventing the reel 200 from falling in the accommodation space 50 even in such a usage pattern.

  FIG. 14 is an enlarged cross-sectional view of a range surrounded by a two-dot chain line XIV in FIG. With reference to FIGS. 1 and 14, in reel package 10 in the present embodiment, a plurality of grooves 81 are formed in support portions 21, 31, and 41.

  The plurality of grooves 81 are recessed from the curved surfaces 21a, 31a, 41a, and extend along the circumferential direction of the curved surfaces 21a, 31a, 41a. The plurality of grooves 81 are arranged at intervals in the axial direction of the curved surfaces 21a, 31a, 41a. The plurality of grooves 81 are formed over the entire width of the curved surfaces 21a, 31a, 41a. The plurality of grooves 81 are formed so as to continuously extend between the curved surface 21a, the curved surface 31a, and the curved surface 41a.

  According to such a configuration, even if the number of reels 200 accommodated in the reel package 10 is reduced, the outer edge of the reel 200 is fitted in the groove 81, so that the reel 200 can be prevented from falling.

[Reel package handle structure]

  Between the handle part 90 and the support part 31 and the support part 41, bent portions 91 are respectively provided. The bent portion 91 has the same structure as the bent portion 51 and the bent portion 52 described above, and the resin molded body 15 is formed so that it can be bent at the bent portion 91. Thereby, the handle portion 90 is formed to be bendable with respect to the end portions of the support portion 31 and the support portion 41.

  Further, a presser part 94 is formed in the handle part 90. In the present embodiment, the presser portion 94 is formed by the bottom portion of the concave portion 93. As shown in FIG. 3 and FIG. 4, when the operator holds the handle 90 and tilts it toward the opening 56 while holding the handle 90, the outer periphery of the reel 200 is turned into the curved surfaces 21 a, 31 a, 41 a. It is formed so that it can be pressed toward.

  According to such a configuration, since the operator can carry the reel package 10 while holding the handle portion 90, the workability during carrying can be improved. In particular, when taking out a plurality of reel packages 10 packed in a separate box from the separate boxes, it is difficult to grip the reel package 10, and therefore the handle 90 is used more effectively.

  Further, the handle portion 90 is formed to be bendable with respect to the end portions of the support portion 31 and the support portion 41. For this reason, the inclination of the handle portion 90 can be changed to a reasonable angle in accordance with how the operator holds the reel package 10 and the attitude of the reel package 10 when carrying the reel package 10. Further, the operator can press the outer periphery of the reel 200 with the presser portion 94 while holding the handle portion 90.
