In this case, the foamed resins 30 and 37 can be disposed in the main body side gap 23 and the lid side gap 32, respectively. Here, the first main body side wall portion 21 and the second main body side wall portion 22 are connected only on the outer peripheral side of the opening of the concave portion 14, and the main body portion 12 is integrally formed. There is no joint between the main body side wall 21 and the second main body side wall 22. Further, the first lid side wall portion 31a and the second lid side wall portion 31b are connected only on the outer peripheral side of the lid side gap 32, and the lid portion 13 is integrally formed. There is no joint between the first lid side wall 31a as the side wall and the second lid side wall 31b as the second lid side wall. Therefore, it is possible to reduce the risk of damage to the storage box 11 generated from these joints.

  According to the present embodiment, the main body side gap 23 and the lid side gap 32 are filled with the foamed resins 30 and 37, respectively. Therefore, even when the storage box 11 collides with another object or the storage box 11 falls, the impact due to the collision is absorbed by the foamed resins 30 and 37 and the storage box 11 is pulled. The possibility that the predetermined object 19 accommodated in the container will be damaged can be reduced. In this case, there is no seam between the first main body side wall 21 and the second main body side wall 22 and between the first lid side wall 31a and the second lid side wall 31b. The injected uncured liquid foamed resins 30 and 37 do not leak. Therefore, the foamed resins 30 and 37 can be reliably filled in the main body side gap 23 and the lid side gap 32, respectively.

  Moreover, according to this embodiment, since the main body side through-holes 16a-16d are provided with two or more, specifically four, the main body side space | gap 23 can be filled with the foaming resin 30 more efficiently. That is, the foamed resin 30 is injected using any one of the main body side through holes 16a to 16d, and the air that is not used for injection is used as a so-called air hole, so that air may be included in the main body side gap 23. The foamed resin 30 can be filled while reducing the above. Further, since a plurality, specifically four, of the lid-side through holes 18a to 18d are provided, the lid-side gap 32 can be more efficiently filled with the foamed resin 37. In addition, it is good also as a structure in which at least any one of main body side through-holes 16a-16d and lid side through-holes 18a-18d is provided with two or more.

First, the manufacturing method of the main-body part 12 with which the storage box 11 is equipped is demonstrated. In manufacturing the main body 12, a 3D printer is mainly used. That is, it manufactures so that the material which comprises the main-body part 12 may be laminated | stacked from the lower layer side. As materials, a water-soluble resin is used as a first main body side resin that is insoluble in water as the first liquid and a second main body side resin that is soluble in water. The first main body side resin is ejected using a first nozzle provided in the 3D printer. The water-soluble resin is ejected using a second nozzle different from the first nozzle provided in the 3D printer. A structure formed by stacking water-soluble resins is also referred to as an auxiliary material in a 3D printer product.

Specifically, first, after a portion 41a corresponding to the first bottom wall portion 24a shown in FIG. 10 is formed, the first main body side resin is formed on the peripheral portion of the portion 41a corresponding to the first bottom wall portion 24a. Are laminated to form a part of the portion 43a corresponding to the first side wall portion 26a, and a water-soluble resin is laminated to the portion 44 corresponding to the body-side gap 23. Since the water-soluble resin laminated on the portion 44 corresponding to the main body side gap 23 is removed later, this portion becomes the main body side gap 23.

After only the thickness L ₂ minutes of the portion 44 corresponding to the body side gap 23 by laminating a water-soluble resin, the portion 43a corresponding to the first side wall portion 26a in the same thickness are stacked first body side resin, water A portion 41b corresponding to the second bottom wall portion 24b is formed on the conductive resin. Specifically, after the water-soluble resin is laminated to form the portion 44 corresponding to the main body side gap 23, the portion 41b corresponding to the second bottom wall portion 24b is again formed thereon by the first main body side resin. The thickness L is laminated for ₃ minutes. Further, the first main body side resin is continuously laminated on the portion 43a corresponding to the first side wall portion 26a by the same thickness. Further, a water-soluble resin is continuously laminated on the periphery of the portion 44 corresponding to the main body side gap 23 to form a portion extending in the Z-axis direction of the main body side gap 23 by the same thickness.

Further, the portion 43a corresponding to the first side wall portion 26a is laminated with the first main body side resin with the same thickness. Further, a portion 44 corresponding to the main body side gap 23 is laminated with a water-soluble resin with the same thickness. FIG. 12 is a cross-sectional view showing a state in which a portion 43a corresponding to the first side wall portion 26a, a portion 43b corresponding to the second side wall portion 26b, and a portion 44 corresponding to the main body side gap 23 are formed. In FIG. 12, the upper diagram corresponds to the diagram viewed from the direction of the arrow Z, and the lower diagram is a cross-sectional view taken along the line XII-XII in the upper diagram.

  Next, as a third body portion forming step (S13), after the second body portion forming step, a portion 43a corresponding to the formed first side wall portion 26a and a portion corresponding to the second side wall portion 26b. On the portion 43b and the portion 44 corresponding to the main body side gap 23, a portion corresponding to the main body side connecting portion 29 is formed by the first main body side resin using a 3D printer.

In FIG. 13, the upper diagram corresponds to the diagram viewed from the direction of the arrow Z, and the lower diagram is a cross-sectional view taken along the line XIII-XIII in the upper diagram.

Referring to FIG. 13, the first resin is placed on the portion 43 a corresponding to the first side wall portion 26 a, the portion 43 b corresponding to the second side wall portion 26 b, and the portion 44 corresponding to the main body side gap 23. laminated by the thickness L ₅ forming part 45 corresponding to the body-side connecting part 29. In this case, only the first main body side resin is used. Here, when forming the portion 45 corresponding to the main body side connecting portion 29, the first main body side resin is not laminated on the portions corresponding to the four main body side through holes 16a to 16d, and the main body side through holes 16a to 16a are not stacked. Four holes 46a, 46b, 46c, 46d corresponding to 16d are provided. That is, the first main body side resin is laminated while avoiding portions corresponding to the four main body side through holes 16a to 16d. In a portion corresponding to the bottom of these holes 46a to 46d, a portion 44 corresponding to the main body side gap 23 in which the water-soluble resin is laminated is located.

  Thus, after forming the external shape of the main-body part 12 with a 3D printer, it transfers to an auxiliary material removal process (S14). Specifically, a structure formed by stacking water-soluble resins is removed from the main body 12. FIG. 14 is a cross-sectional view showing a state in which a main body side gap is formed in a portion 44 corresponding to the main body side gap 23. In FIG. 14, the upper diagram corresponds to the diagram viewed from the direction of the arrow Z, and the lower diagram is a cross-sectional view taken along the line XIV-XIV in the upper diagram.

  Referring to FIG. 14, water is introduced from all or any of four holes 46a to 46d. By introducing water, the water-soluble resin disposed in the portion 44 corresponding to the main body side gap 23 is dissolved in water. In this case, since the first body-side resin is insoluble in water, only the portion where the water-soluble resin is laminated is dissolved in water. After the water-soluble resin is dissolved in water, the main body 12 is tilted or turned over, and the water in which the water-soluble resin is dissolved is discharged from any of the holes 46a to 46d. Such work is repeated a plurality of times as necessary. In this manner, the main body side gap 47 is formed in the portion 44 corresponding to the main body side gap 23 where the water-soluble resin is disposed as an auxiliary material. As a result of removing the water-soluble resin, each of the holes 46 a to 46 d becomes a through hole extending from the outside to the main body side gap 47.

  Next, the process proceeds to the main body side filling resin injection step (S15). The main body side filling resin is a curable resin and is liquid in an uncured state. That is, the main body side filling resin has fluidity in an uncured state. As the main body side filling resin, for example, a foamed resin having foamability after curing is employed.

In FIG. 15, the upper diagram corresponds to the diagram viewed from the direction of the arrow Z, and the lower diagram is a cross-sectional view taken along XV-XV in the upper diagram.

  Referring to FIG. 15, main body side filling resin 48 is injected from any of holes 46 a to 46 d into main body side gap 47 formed by removing a structure composed of a water-soluble resin. In this case, the main body side filling resin 48 is injected from any of the holes 46a to 46d using a member such as a syringe. At this time, the holes 46 a to 46 d into which the main body side filling resin 48 is not injected become air holes through which air in the main body side gap 47 comes out.

  After injecting the main body side filling resin 48, the main body side filling resin 48 is cured by heating or the like, and the main body side filling resin 48 is disposed in the main body side gap 47. In addition, after hardening the main body side filling resin 48, as above-mentioned, about the wall surface which comprises the holes 46a-46d, a thread groove is formed using a tap. Thus, the main-body part 12 with which the storage box 11 which concerns on one Embodiment of this invention is equipped is formed.

The outer shape of the portion 51a corresponding to the first lid side wall portion 31a is a rectangular shape with four rounded corners as shown in the upper diagram in FIG.

  Here, when forming the portion 51a corresponding to the first lid side wall portion 31a, the portions corresponding to the four insertion holes 17a to 17d are not stacked with the first main body side resin, and are inserted into the insertion holes 17a to 17d. Four corresponding holes 53a, 53b, 53c, and 53d are provided. That is, the first main body side resin is laminated while avoiding portions corresponding to the four insertion holes 17a to 17d.

  Next, in the second lid forming step (S22), a portion corresponding to the lid side connecting portion 35 is formed on the portion 51a corresponding to the first lid side wall portion 31a. Further, a portion corresponding to the lid side gap 32 is formed. FIG. 18 is a diagram illustrating a state where a portion corresponding to the lid-side connecting portion 35 is formed. In FIG. 18, the upper diagram corresponds to the diagram viewed from the direction of the arrow Z, and the lower diagram is a cross-sectional view taken along the line XVIII-XVIII in the upper diagram.

Referring to FIG. 18, after forming portion 51a corresponding to first lid side wall portion 31a, a predetermined distance from the peripheral portion of other surface 52b of portion 51a corresponding to first lid side wall portion 31a. The first lid-side resin is laminated at a portion 54 that is located only on the inner side and corresponds to the lid-side connecting portion 35. In addition, the water-soluble resin is laminated on the portion 55 corresponding to the lid-side gap 32 together with the lamination of the first lid-side resin in the portion 54 corresponding to the lid-side connecting portion 35. The water-soluble resin is laminated by the thickness L _{12 of the} portion 55 corresponding to the lid-side gap 32, and the first lid-side resin is laminated on the portion 54 corresponding to the lid-side connecting portion 35 with the same thickness. A portion 54 corresponding to the lid-side connecting portion 35 is formed with the lid-side resin, and a portion 55 corresponding to the lid-side gap 32 is formed with the water-soluble resin.

  After the second lid forming step, in the third lid forming step (S23), on the portion 54 corresponding to the lid-side connecting portion 35 formed and the portion 55 corresponding to the lid-side gap 32, A portion corresponding to the second lid side wall portion 31b is formed by the first lid side resin using a 3D printer.

In FIG. 19, the upper diagram corresponds to the diagram viewed from the direction of the arrow Z, and the lower diagram is a cross-sectional view taken along the line XIX-XIX in the upper diagram.

Referring to FIG. 19, the first lid side resin is laminated by a thickness L ₁₃ on the portion 54 corresponding to the lid side connecting portion 35 and the portion 55 corresponding to the lid side gap 32, and the second lid side wall. A portion 51b corresponding to the portion 31b is formed. Here, when the portion 51b corresponding to the second lid side wall portion 31b is formed, the first lid side resin is not laminated on the portions corresponding to the four lid side through holes 18a to 18d, and the lid side through hole is formed. Four holes 56a, 56b, 56c, and 56d corresponding to 18a to 18d are provided. That is, the first lid side resin is laminated while avoiding portions corresponding to the lid side through holes 18a to 18d. In a portion corresponding to the bottom of these holes 56a to 56d, a portion 55 corresponding to the lid side gap 32 in which the water-soluble resin is laminated is located.

  Thus, after forming the external shape of the cover part 13 with a 3D printer, it transfers to an auxiliary material removal process (S24). That is, the structure formed by the lamination of the water-soluble resin is removed from the lid portion 13 as in the case of the main body portion 12 described above. FIG. 20 is a cross-sectional view showing a state in which a gap is formed in a portion 55 corresponding to the lid-side gap 32. 20, the upper diagram corresponds to the diagram viewed from the direction of the arrow Z, and the lower diagram is a cross-sectional view taken along the line XX-XX in the upper diagram.

  Referring to FIG. 20, specifically, water is poured from all or any of four holes 56a to 56d. By adding water, the water-soluble resin is dissolved in water. In this case, since the first lid-side resin is insoluble in water, the water-soluble resin is laminated and only the portion is dissolved in water. After the water-soluble resin is dissolved in water, the lid portion 13 is tilted or turned over, and the water in which the water-soluble resin is dissolved is discharged from any of the holes 56a to 56d.

In particular, since the so-called wall structure constituting the storage box 11 is double, there is no seam, and the foamed resin is filled between the walls of the double structure, the risk of breakage is extremely low. Therefore, data can be logged more reliably.

  In particular, it is assumed that a plurality of such data logging devices 66 are mounted on a drone and scattered at predetermined intervals in order to collect predetermined data over a wide area of a certain land, for example. Even in such a case, the impact due to the collision at the time of dropping is absorbed by the structure of the storage box 11 in which the so-called wall has a double structure and is filled with foamed resin therebetween. That is, the risk of damage to the data logging device 66 when dropped can be greatly reduced. Therefore, data can be collected and utilized more reliably.
