(Configuration of circular article storage box 100)
Hereinafter, one embodiment of a circular article storage box according to the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an outline of the overall configuration of a circular article storage box 100 according to the present invention in a part of an assembly process. FIG. 2 is a plan view showing the circular article storage box 100 shown in FIG. 1 in an unfolded state. Moreover, in each figure referred in this embodiment and each modification, the to-be-contained object WK is shown with the dashed-two dotted line, and the fold of the state which is not folded is shown with the broken line. The circular article storage box 100 stores a storage object WK including a reel-type holder that holds a sheet body that holds a large number of small electronic parts and other small articles for transportation and storage. .

  The circular article storage box 100 is configured by mainly forming a bottom plate 110, a side wall 120, and a lid body 140 on a single cardboard material extending in a strip shape. Among these, the bottom plate 110 is a portion on which the object WK is placed, and is formed in a rectangular shape in plan view. More specifically, the bottom plate 110 is formed such that the length in the longitudinal direction (the left-right direction in the drawing) is longer than the outer diameter of the object WK, and the width in the width direction (the vertical direction in the drawing) orthogonal to the longitudinal direction. The length is formed to the same length as the outer diameter of the object WK. The bottom plate 110 can also be formed in a square shape in plan view.

  Further, in the present embodiment, the bottom plate 110 is formed such that the corrugated corrugated board material extends in parallel along the longitudinal direction. Here, the corrugation means a so-called flow direction in which a corrugated core constituting the corrugated board material is formed. Note that the bottom plate 110 can also be formed such that the corrugated corrugated board material extends in parallel along the width direction. Further, in FIG. 2, the wave direction is shown on the bottom plate 110. The bottom plate 110 is formed with fold lines 111 formed of perforations for folding the four corner portions inward. Here, the perforation is a portion that is easily folded by forming through or through notches in the corrugated board material intermittently.

  The side wall 120 is a wall-shaped component that is disposed on four sides of the object to be stored WK placed on the bottom plate 110 and surrounds the object to be stored WK, and mainly includes a pair of first side walls 121 and 122 and a pair of second walls. Side walls 125 and 126 are provided. The first side walls 121 and 122 are provided so as to stand on two edges that face each other on the wave direction side of the four edges of the bottom plate 110. More specifically, the first side walls 121 and 122 extend outward through the creases 123 formed of creases formed on two edges facing each other on the wave direction side of the bottom plate 110, respectively. Is formed.

  In this case, the first side walls 121 and 122 are formed such that the length (in other words, the height) extending in the wave direction (the left-right direction in the drawing) is slightly longer than the thickness of the container WK, and the wave direction The length in the width direction (vertical direction in the figure) orthogonal to the length is the same as the length in the width direction (vertical direction in the figure) of the bottom plate 110. Further, the first side walls 121 and 122 are formed with fold lines 124 each having a perforation in a state of being connected to the fold line 111 of the bottom plate 110 on both end sides in the width direction (the vertical direction in the drawing). These four folds 124 are for folding the both end portions of the first side walls 121 and 122 inward. The crease is a portion that is easily folded by being softened by folding the corrugated board material in advance or by using a tool.

  The second side walls 125 and 126 are provided so as to stand on two edges that face each other in the width direction orthogonal to the wave direction of the four edges of the bottom plate 110. More specifically, the second side walls 125 and 126 are respectively connected via creases 127 formed of creases formed on two edges facing each other on the width direction orthogonal to the wave direction of the bottom plate 110. It is formed to extend outward.

  In this case, the second side walls 125 and 126 are formed such that the length (in other words, the height) extending in the width direction orthogonal to the wave direction is slightly longer than the thickness of the container WK, and the wave direction The length extending in parallel with the bottom plate 110 is the same as the length between the two folds 111 formed on the bottom plate 110. A crease 128 made of a crease is formed at each end of the second side walls 125 and 126 on the wave direction side, and a fixed wall 130 is formed via each of these four folds 128.

  The fixed wall 130 extends on the bottom plate 110 from both end portions of the second side walls 125 and 126 so as to stand up to the pair of first side walls 121 and 122 and contacts a part of the outer peripheral portion of the object to be stored WK. The fixed walls 130 facing each other in the width direction through the first side walls 121 and 122 constitute a pair. The two pairs of fixed walls 130 each include a first circumscribing portion 131 and a second circumscribing portion 132.

  The first circumscribed portion 131 is a portion that is bent from the second side walls 125 and 126 and comes into contact with the outer peripheral portion of the object to be stored WK, and is formed to extend in a band shape. In this case, each of the first circumscribed portions 131 of the pair of fixed walls 130 on the first side wall 121 side of the two pairs of fixed walls 130 is connected to the bottom plate 110 via a fold 133 that is partially perforated. While being connected, the other part is separated from the first side wall 121. In addition, each of the first circumscribed portions 131 of the pair of fixed walls 130 on the first side wall 122 side of the two pairs of fixed walls 130 is separated from the bottom plate 110 and the first side wall 122.

  The second circumscribing portion 132 is a portion that comes into contact with the portion of the article WK placed on the bottom plate 110 that faces the first side walls 121 and 122, and is formed at the tip of each first circumscribing portion 131. It is formed to extend in a band shape through a fold line 134 formed of a folded fold. In this case, the two second circumscribed portions 132 of the fixed walls 130 constituting the pair are overlapped with each other between the outer peripheral portion of the object WK placed on the bottom plate 110 and the first side walls 121 and 122. Is formed.

  The lid 140 is a component that covers the opening 150 formed on the opposite side of the bottom plate 110 by the side wall 120 disposed on the bottom plate 110 so as to be openable and closable, on both ends of the pair of first side walls 121 and 122. A pair of first lid body 141 and second lid body 142 each extend outward through a crease 129 formed of a crease formed respectively.

  Among these, the 1st cover body 141 is formed in the square-plate shape of the magnitude | size which covers the area | region of the illustration left half of the opening part 150 in the figure. The second lid 142 is formed in a rectangular plate shape having a size that covers the remaining half of the right side of the opening 150 in the figure. In each of the first lid body 141 and the second lid body 142 on each of the corners on the first side wall 121, 122 side, a fold line 143 made of a perforation for folding each corner section is formed. ing. In addition, the first lid 141 and the second lid 142 are formed with folds 144 formed of creases on both side edges on the distal end side opposite to the fold 129, and through the folds 144. The support pieces 160 are formed so as to protrude outward.

  As shown in FIG. 3, the support piece 160 prevents the first lid 141 and the second lid 141 from sinking when the opening 150 is closed by the first lid 141 and the second lid 142. The two parts are respectively formed on both edge portions of the first lid 141 and the second lid 142 to constitute a pair. The two pairs of support pieces 160 are constituted by plate-like bodies having a length that reaches the upper surface of the bottom plate 110 when the first lid 141 and the second lid 142 are respectively disposed on the opening 150. ing. That is, each support piece 160 is formed at the same height as the second side walls 125 and 126 and the fixed wall 130. In FIG. 3, a part of the two support pieces 160 is indicated by a broken line.

  The two pairs of support pieces 160 are formed at positions retracted inward with respect to the respective front end portions of the first lid 141 and the second lid 142. More specifically, each of the four support pieces 160 is in a suspended state in which the first cover body 141 and the second cover body 142 are respectively disposed on the opening 150 and each support piece 160 is folded to the bottom plate 110 side. In FIG. 2, the outer peripheral surface of the object WK disposed on the bottom plate 110 is not in contact with the outer peripheral surface.

(Operation of circular article storage box 100)
Next, the operation of the circular article storage box 100 configured as described above will be described. First, the operator who accommodates the article WK in the circular article storage box 100 prepares the circular article storage box 100 together with the article WK. In this case, the circular article storage box 100 is prepared in a flat plate-like unfolded state in which a bottom plate 110, a side wall 120, a fixed wall 130, a lid 150, and a support piece 160 are formed on a single sheet-like cardboard material. (See FIG. 2).

  Next, the operator assembles the circular article storage box 100 in an unfolded state halfway. Specifically, as shown in FIG. 4, the worker folds the second side walls 125 and 126 formed on both sides in the width direction of the bottom plate 110 at the fold 127 to stand. In this case, two pairs of fixed walls 130 are integrally connected to the second side walls 125 and 126, and the pair of fixed walls 130 on the first side wall 121 side of these fixed walls 130. Are integrally connected to the bottom plate 110. For this reason, the fixed wall 130 stands up with the standing up of the second side walls 125 and 126.

  Therefore, when raising the second side walls 125 and 126, the operator folds the folds 133 and the folds 133 while folding the folds 111 and 128 as viewed from the inside of the circular article storage box 100. As a result, the pair of fixed walls 130 on the first side wall 121 side are arranged while moving upright on the inner side of the bottom plate 110, and a part of the bottom plate 110 connected to the pair of fixed walls 130 (fold line 111). The first side wall 121 rises to the bottom plate 110 side through the fold 123 by folding the outer corners) to the inside of the bottom plate 110. That is, the operator can raise the first side wall 121 and the first lid 141 to the bottom plate 110 side automatically by raising the second side walls 125 and 126.

  Further, in this case, the fixed wall 130 is bent at the fold line 134 so that the pair of second circumscribed portions overlap each other at a position facing the first side wall 121. Then, the operator folds the folds 124 and 143 in the rising process of the first side wall 121 to fold both ends of the first side wall 121 and the outer side of each fold 143 in the first lid 141 inward. However, the folds 129 and 144 are valley-folded.

  Thereby, the operator can arrange | position the 1st cover body 141 on the opening part 150 formed by standing up of the 2nd side walls 125 and 126 and the fixed wall 130. FIG. In this case, the operator inserts the support pieces 160 formed on both edge portions of the first lid 141 into the second side walls 125 and 126. Accordingly, as shown in FIG. 6, the operator can assemble half of the circular article storage box 100 with the first lid 141 in the lid 140 closing half of the opening 150.

  Next, the worker arranges the object WK in the circular article storage box 100. Specifically, as shown in FIG. 6, the worker arranges the object WK on the bottom plate 110. In this case, the operator can insert the object to be stored WK from the open part of the circular article storage box 100 assembled halfway, that is, from the first side wall 122 side. The operator places the object to be stored WK on the bottom plate 110 of the circular article storage box 100 developed in a flat plate shape while the circular article storage box 100 is in the middle (the first lid 141 is placed on the opening 150). (Closed state) can also be assembled.

  Next, the operator assembles the circular article storage box 100 in a closed state. Specifically, as shown in FIG. 1, the worker arranges the pair of fixed walls 130 extending toward the first side wall 122 while being moved upright on the inner side of the bottom plate 110 by bending each of the fixed walls 130 at the fold 128. At the same time, the fold lines 134 in the pair of fixed walls 130 are bent, and the second circumscribed portions 132 are overlapped with each other. Thereby, on the bottom plate 110, the side wall 120 is formed in an octagonal shape in contact with the outer peripheral portion of the object WK by the pair of second side walls 125, 126 and two pairs of fixed walls 130. In this case, since the fixed wall 130 is separated from the bottom plate 110, the first side wall 122 does not rise while maintaining the collapsed state even if the fixed wall 130 is moved upright.

  Next, the operator troughly folds the folds 111 and 123 on the first side wall 122 side, the fold line 124 on the first side wall 122 and the fold line 143 on the second lid 142, respectively, The first side wall 122 is erected while folding the corners, both end portions of the first side wall 122 and the outer portions of the second lid 142 from the folds 143. Then, the operator folds the fold 129 of the second lid 142 and moves the second lid 142 onto the opening 150, and folds the two folds 144 of the second lid 142 respectively. The second lid 142 is placed on the opening 150 while the pair of support pieces 160 of the two lids 142 are inserted inside the second side walls 125 and 126 (see FIG. 3).

  In this case, the operator smoothly inserts the support pieces 160 inside the second side walls 125 and 126 because each support piece 160 is formed at a position that does not contact the outer peripheral surface of the object to be stored WK disposed on the bottom plate 110. be able to. Thereby, as shown in FIG. 4, the circular article storage box 100 is completed in a state in which the articles to be stored WK are completely stored. The operator may connect the first lid body 141 and the second lid body 142 to each other by using an adhesive tape such as a gum tame or a fastener such as a stapler so as not to open easily. it can.

  In such a storage state, the circular article storage box 100 is formed with a length in which two pairs of support pieces 160 reach the bottom plate 110 to support the first lid 141 and the second lid 142 on the bottom plate 110. Therefore, each sinking of the first lid 141 and the second lid 142 is prevented. In this case, the circular article storage box 100 has corrugated corrugated corrugations formed in the longitudinal direction between the first lid body 141 and the second lid body 142, so that the second side walls 125 and 126, which will be described later, are fixed. Like the wall 130, the rigidity of the support piece 160 can be increased. Further, as shown in FIG. 4, the circular article storage box 100 is provided in a state in which the pair of first side walls 121 and 122 are in close contact with the second circumscribed portion 132 of the pair of fixed walls 130. Thus, the shape of the side wall 120 formed in an octagon is maintained, and the object WK is stably accommodated.

  The circular article storage box 100 has a pair of second side walls 125, 126, and two sets, because the corrugated corrugated material is formed in the longitudinal direction between the first lid 141 and the second lid 142. Waves of a certain pair of fixed walls 130 are formed along the circumferential direction of the object WK. In other words, the circular article storage box 100 surrounds the object to be stored WK in a state where the cores constituting the pair of second side walls 125 and 126 and the two pairs of fixed walls 130 stand up. As a result, the circular article storage box 100 has a pair of second side walls 125 and 126 and two pairs of fixed walls 130 formed in an octagonal shape in plan view from the vertical and parallel directions with respect to the side wall 120. Therefore, the object WK can be stably stored.

  Next, when the worker takes out the object WK from the circular article storage box 100, the operator pulls the first lid 141 and the second lid 142 upward to open the object WK. It can be taken out. In this case, as shown in FIG. 6, the operator opens only the second lid 142 side to be in an unfolded state, and then opens the pair of fixed walls 130 on the second lid 142 side to open the bottom plate 110. The to-be-contained object WK can also be drawn out to the first side wall 122 and the second lid 142 side.

  As can be understood from the above description of operation, according to the embodiment, the circular article storage box 100 includes the first support piece 160 that supports the first lid body 141 and the second lid body 142 that constitute the lid body 140. Since the first cover body 141 and the second cover body 142 are formed on both side portions on the respective front end portions side, a part of the material on both sides of the second side walls 125 and 126 formed to protrude from the bottom plate 110 is supported by the support piece. Can be used effectively. Thereby, the circular article storage box 100 according to the present invention can improve the material yield as compared with the conventional case.

  Furthermore, in carrying out the present invention, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the object of the present invention. In the description of each modification, the same reference numerals are assigned to the same parts as those in the above embodiment.

  For example, in the above-described embodiment, the first lid body 141 and the second lid body 142 are formed to have a size that covers each half of the opening 150. However, the 1st cover body 141 and the 2nd cover body 142 should just cover the whole opening part 150 as a whole. Accordingly, the first lid 141 and the second lid 142 can be formed larger in size than the other.

  In the above-described embodiment, the pair of second side walls 125 and 126 are spaced with the same length as the outer diameter of the object WK. In this case, the same length as the outer diameter of the object to be stored WK does not mean completely the same, but includes some length if the position shift of the object to be stored WK can be prevented. Further, the pair of second side walls 125 and 126 can be formed to have a length sufficiently longer than the outer diameter of the object to be stored WK. In this case, the operator can prevent misalignment of the object to be stored WK by disposing padding such as a cushion material between the object to be stored WK and the second side walls 125 and 126.

  In the above embodiment, the circular article storage box 100 is configured to form an octagon with the second side walls 125 and 126 and the fixed wall 130 so as to surround the periphery of the object to be stored WK. However, the circular article storage box 100 can be configured to surround the object WK by forming a hexagonal shape other than an octagonal shape with the second side walls 125, 126 and the fixed wall 130, for example. In this case, the fixed wall 130 omits the second circumscribing portion 132 and includes only the first circumscribing portion 131, and the distal end portions of the first circumscribing portion 131 in the fixed wall 130 constituting the pair are connected to the first side wall 121. It can be configured to abut at the central portion.

  In the above embodiment, the fixed wall 130 on the first side wall 121 side is connected to the bottom plate 110.
