[0003] [Patent Document 1] Japanese Patent Application Publication No. 8-150518 Summary of the Invention [Problem to be solved by the invention]

[0004] When the opening is opened and closed by the shutter, a guide for guiding the movement of the shutter may be formed in the parts container. In this case, for example, the guide may be formed of a plate-like member. That is, the shutter moves between the plate-like members provided inside the parts container.

Therefore, if the distance between the above-mentioned plate-like members becomes too short, it may be difficult to manufacture the container body. Furthermore, if the distance between the above-mentioned plate-like members becomes too short, a part of the mold for manufacturing the container body may become weak. Therefore, there is a demand for a parts container that can easily form a guide for guiding the movement of the shutter.

[0017] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. FIGS. 1 to 12 are diagrams showing an embodiment. Each of the figures shown below is a schematic diagram. Therefore, the size and shape of each part are appropriately exaggerated to facilitate understanding. In addition, the present invention can be modified appropriately within the scope of the technical idea. In each of the figures shown below, the same parts are given the same reference numerals, and some detailed explanations may be omitted. In addition, the numerical values ​​such as the dimensions of each member and the material names described in this specification are examples of embodiments, and can be appropriately selected and used without being limited thereto. In this specification, terms that specify shapes and geometric conditions, such as parallel, orthogonal, and vertical, are interpreted to include substantially the same state in addition to their strict meanings.

[0018] The component container 10A according to the present embodiment is a container for storing a large number of chip components. The chip components may be, for example, electronic components such as multi-layer ceramic capacitors (MLCCs (Multi-Layer Ceramic Capacitors)). The size of the chip components may be approximately 0.25 mm×0.125 mm. The size of the chip components may also be approximately 0.40 mm×0.20 mm. The size of the chip components may also be approximately 0.60 mm×0.30 mm. Furthermore, the size of the chip components may also be approximately 1.00 mm×0.50 mm.

[0019] 1, the component container 10A includes a main body 10 having a main body opening 11, and a shutter 60 for opening and closing the main body opening 11. The component container 10A may further include a slider 70 for sliding the shutter 60. Of these, the shutter 60 and the slider 70 are slidable relative to the main body 10.

[0020] The above-mentioned main body 10 may be, for example, a bulk case conforming to JIS C 0806-6:2006 or IEC 60286-6. The main body 10 has a first container member 20 and a second container member 40 assembled to the first container member 20. The main body 10 also includes a side wall surface 12 formed on the periphery, and the above-mentioned main body opening 11 for removing the chip components is formed in a part of the side wall surface 12. Furthermore, an operating portion 13 for operating the shutter 60 and the slider 70 is formed in a part of the side wall surface 12 different from the main body opening 11.

[0021] Next, the first container member 20 will be described. As shown in Fig. 1 and Fig. 2, the first container member 20 has a first surface portion 21, a first side wall portion 22 provided around the first surface portion 21, and a first inner wall portion 30 provided inside the first side wall portion 22. Of these, the first surface portion 21 has a rectangular shape in a plan view. In this specification, "plan view" refers to viewing an object from the normal direction (Z direction) of the first surface portion 21 and the second surface portion 41.

[0022] The thickness (Z-direction distance) of the first surface portion 21 may be 0.5 mm or more and 2 mm or less. When the thickness is 0.5 mm or more, it is possible to suppress a decrease in the rigidity of the first container member 20. When the thickness is 2 mm or less, it is possible to suppress a decrease in the transparency of the first surface portion 21.

[0023] The first side wall portion 22 is formed along the periphery of the first surface portion 21 so as to protrude from the first surface portion 21 toward the second container member 40 (the positive side in the Z direction). The first side wall portion 22 and a second side wall portion 42 of the second container member 40, which will be described later, form the side wall surface 12 of the main body 10.

[0024] The first side wall portion 22 includes a first long side portion 22a, a second long side portion 22b, a first short side portion 22c, and a second short side portion 22d. The first long side portion 22a and the second long side portion 22b face each other and extend along the longitudinal direction (X direction) of the first surface portion 21. On the other hand, the first short side portion 22c and the second short side portion 22d face each other and extend along the width direction (Y direction) of the first surface portion 21. The first short side portion 22c and the second short side portion 22d extend between the first long side portion 22a and the second long side portion 22b. Here, the X direction and the Y direction are orthogonal to each other. The Z direction is perpendicular to both the X direction and the Y direction, and is the thickness direction of the component container 10A.

[0025] Further, the first side wall portion 22 is formed with a first through portion 25 penetrating the first side wall portion 22 in the thickness direction. The first through portion 25 constitutes a part of the main body opening 11. The first through portion 25 corresponds to a fourth through portion 45 of the second container member 40 described later, and the main body opening 11 of the main body 10 is formed by the first through portion 25 and the fourth through portion 45. This first through portion 25 is formed in the first short side portion 22c.

[0026] A second penetrating portion 26 penetrating the first side wall portion 22 in the thickness direction is formed in a portion of the first side wall portion 22 different from the first penetrating portion 25. The second penetrating portion 26 corresponds to a fifth penetrating portion 46 of the second container member 40 described later, and the second penetrating portion 26 and the fifth penetrating portion 46 form the operation portion 13 of the main body 10. This second penetrating portion 26 is formed in the first long side portion 22a. Therefore, the operation portion 13 is formed in the first long side portion 22a.

[0027] The first inner wall portion 30 is formed to protrude from the first surface portion 21 toward the second container member 40 (the positive side in the Z direction). In this embodiment, the first inner wall portion 30 includes a first guide member 31a, a second guide member 31b, a first slider guide member 33, a first shutter guide member 38a, a second shutter guide member 38b, and a third shutter guide member 38c, which will be described later. In the following description, the first guide member 31a, the second guide member 31b, the first slider guide member 33, the first shutter guide member 38a, the second shutter guide member 38b, and the third shutter guide member 38c are collectively referred to simply as the first inner wall portion 30.

[0028] 2, a first guide member 31a is provided inside the first container member 20, extending from the vicinity of the first penetrating portion 25 to the vicinity of the first long side portion 22a of the first sidewall portion 22. Also, a second guide member 31b is provided inside the first container member 20, extending from the vicinity of the first penetrating portion 25 to the vicinity of the second long side portion 22b of the first sidewall portion 22. The first guide member 31a and the second guide member 31b are made of plate-like members extending at an angle with respect to the longitudinal direction (X direction) of the first surface portion 21. In this manner, by providing the first guide member 31a and the second guide member 31b, the chip components can be easily guided to the main body opening 11. In this embodiment, a second guide 15 (see Figures 2 and 5) that guides the movement of the chip components is formed by a first guide member 31a and a second guide member 31b (first inner wall portion 30), as well as a third guide member 51a and a fourth guide member 51b (second inner wall portion 50) described later.

[0029] Further, a first slider guide member 33 that guides the movement of the slider 70 is provided inside the first container member 20. The first slider guide member 33 is composed of a plate-shaped member extending from the first guide member 31a along the first long side portion 22a.

[0030] Furthermore, a first shutter guide member 38a and a second shutter guide member 38b are provided on the inside of the first container member 20 near the first short side portion 22c. A third shutter guide member 38c is provided on the inside of the first container member 20 near the first long side portion 22a. The first shutter guide member 38a is made of a plate-like member extending from the first guide member 31a along the first short side portion 22c. The second shutter guide member 38b is made of a plate-like member extending from the second guide member 31b along the first short side portion 22c. The third shutter guide member 38c is made of a plate-like member extending from the first shutter guide member 38a along the first long side portion 22a. In this way, by providing the first shutter guide member 38a, the second shutter guide member 38b, and the third shutter guide member 38c, the shutter 60 can move smoothly. In this embodiment, a first guide 14 (see Figures 3, 4, 6 and 7) that guides the movement of the shutter 60 is formed by the first long side portion 22a and the first short side portion 22c (first side wall portion 22), the first shutter guide member 38a, the second shutter guide member 38b and the third shutter guide member 38c (first inner wall portion 30), the first long side portion 42a and the first short side portion 42c (second side wall portion 42) of the second container member 40 described below, and the fourth shutter guide member 58a, the fifth shutter guide member 58b and the sixth shutter guide member 58c (second inner wall portion 50).

[0031] Here, in this embodiment, as shown in Figs. 2 to 4, the first side wall portion 22 includes a first low side wall portion 27 and a first high side wall portion 28 having a height (Z-direction distance) higher than that of the first low side wall portion 27. In the illustrated example, the first low side wall portion 27 is formed on both sides of the first penetrating portion 25. Also, the portion other than both sides of the first penetrating portion 25 is the first high side wall portion 28. In the first container member 20, the first low side wall portion 27 may or may not be distinguishable from the portion where the first penetrating portion 25 is formed. For example, when the height of the first low side wall portion 27 (height h1 described later) is the same as the height (Z-direction distance) of the portion where the first penetrating portion 25 is formed, in the first container member 20, the first low side wall portion 27 may not be distinguishable from the portion where the first penetrating portion 25 is formed. In the component container 10A, as described below, the first lower side wall portion 27 is joined to a second higher side wall portion 48 of the second container member 40, and the first penetrating portion 25, as described above, forms part of the main body opening 11. Therefore, in the component container 10A, the first lower side wall portion 27 can be distinguished from the portion where the first penetrating portion 25 is formed.

[0032] The height H1 (Z-direction distance, see FIG. 3) of the first lower side wall portion 27 may be the same as the height h1 (Z-direction distance, see FIG. 4) of a first lower inner wall portion 34 of the first inner wall portion 30, which will be described later. This allows the first side wall portion 22 and the first inner wall portion 30 of the first container member 20 and the second side wall portion 42 and the second inner wall portion 50 of the second container member 40 to come into contact with each other when the first container member 20 and the second container member 40 are joined together, as will be described later. This makes it possible to prevent a decrease in the adhesive strength between the first container member 20 and the second container member 40.

[0033] The height H1 of the first low side wall portion 27 may be 0.3 mm or more and 4.0 mm or less. When the height H1 is 0.3 mm or more, it is possible to suppress the occurrence of deformation such as warping in the first container member 20. Furthermore, when the height H1 is 0.3 mm or more, it is easy to join the first low side wall portion 27 and the second high side wall portion 48 of the second container member 40, which will be described later. Furthermore, when the height H1 is 4.0 mm or less, even if the distance d1 (X-direction distance, see FIG. 3) between the first low side wall portion 27 and the first high inner wall portion 35, which will be described later, is short, the first container member 20 can be easily manufactured. The distance d1 may be 0.2 mm or more and 0.5 mm or less.

[0034] The first high side wall portion 28 is a portion to be joined to a second low side wall portion 47 of the second container member 40, which will be described later. The height H2 (Z-direction distance, see FIG. 4) of the first high side wall portion 28 may be the same as the height h2 (Z-direction distance, see FIG. 3) of a first high inner wall portion 35 of the first inner wall portion 30, which will be described later. As a result, as will be described later, when the first container member 20 and the second container member 40 are joined to each other, the first side wall portion 22 and the first inner wall portion 30 of the first container member 20 and the second side wall portion 42 and the second inner wall portion 50 of the second container member 40 can be brought into contact with each other. Therefore, it is possible to suppress a decrease in the adhesive strength between the first container member 20 and the second container member 40.

[0035] The height H2 of the first high sidewall portion 28 may be 3.5 mm or more and 7.5 mm or less. By setting the height H2 to 3.5 mm or more, the height H3 (Z-direction distance, see FIG. 6) of the second low sidewall portion 47 to be joined to the first high sidewall portion 28 described later can be reduced. Therefore, even if the distance d3 (X-direction distance, see FIG. 6) between the second low sidewall portion 47 described later and the second high inner wall portion 55 described later is short, the second container member 40 can be easily manufactured. In addition, by setting the height H2 to 7.5 mm or less, the height H3 of the second low sidewall portion 47 described later can be increased, and deformation such as warping can be suppressed from occurring in the second container member 40. The distance d2 may be 0.2 mm or more and 0.5 mm or less.

[0036] 2 to 4, the first inner wall portion 30 includes a first low inner wall portion 34 and a first high inner wall portion 35 having a height (Z-direction distance) higher than the first low inner wall portion 34. In the illustrated example, of the first inner wall portion 30, a part of the first shutter guide member 38a and the third shutter guide member 38c form the first low inner wall portion 34. Also, of the first inner wall portion 30, the first guide member 31a, the second guide member 31b, the first slider guide member 33, the other part of the first shutter guide member 38a and the second shutter guide member 38b form the first high inner wall portion 35.

[0037] The first low inner wall portion 34 is a portion to be joined to a second high inner wall portion 55 of the second container member 40, which will be described later. The height h1 of the first low inner wall portion 34 may be 0.3 mm or more and 4.0 mm or less. When the height h1 is 0.3 mm or more, it is possible to suppress the occurrence of deformation such as warping in the first container member 20. Furthermore, when the height h1 is 0.3 mm or more, it becomes easy to join the first low inner wall portion 34 to a second high inner wall portion 55 of the second container member 40, which will be described later. Furthermore, when the height h1 is 4.0 mm or less, it is possible to easily manufacture the first container member 20 even when the distance d2 between the first low inner wall portion 34 and the first high side wall portion 28 is short.

[0038] The first high inner wall portion 35 is a portion that is joined to a second low inner wall portion 54 of the second container member 40, which will be described later. The height h2 of the first high inner wall portion 35 may be 3.5 mm or more and 7.5 mm or less. By making the height h2 3.5 mm or more, the height h3 (Z-direction distance, see FIG. 7) of the second low inner wall portion 54, which will be joined to the first high inner wall portion 35, can be made low. Therefore, even if the distance d4 (X-direction distance, see FIG. 7) between the second high side wall portion 48, which will be described later, and the second low inner wall portion 54, which will be described later, is short, the second container member 40 can be easily manufactured. In addition, by making the height h2 7.5 mm or less, the height h3 of the second low inner wall portion 54, which will be described later, can be made high, and deformation such as warping of the second container member 40 can be suppressed.

[0039] In such a first container member 20, the total height of the height H1 of the first lower side wall portion 27 and the height H5 of the first surface portion 21 (Z-direction distance, see FIGS. 3 and 4), and the total height of the height h1 of the first lower inner wall portion 34 and the height H5 of the first surface portion 21 may be less than half of the height H (Z-direction distance, see FIG. 1) of the component container 10A. That is, the following formulas (1) and (2) may be satisfied. H1 + H5 < H / 2 ··· Formula (1) h1 + H5 < H / 2 ··· Formula (2) H: Height of the component container 10A H1: Height of the first lower side wall portion 27 H5: Height of the first surface portion 21 h1: Height of the first lower inner wall portion 34

[0040] Further, the total height of the height H2 of the first upper side wall portion 28 and the height H5 of the first surface portion 21, and the total height of the height h2 of the first upper inner wall portion 35 and the height H5 of the first surface portion 21 may be higher than half of the height H of the component container 10A. That is, the following formulas (3) and (4) may be satisfied. H2 + H5 > H / 2 ··· Formula (3) h2 + H5 > H / 2 ··· Formula (4) H: Height of the component container 10A H2: Height of the first upper side wall portion 28 H5: Height of the first surface portion 21 h2: Height of the first upper inner wall portion 35

[0041] Next, the second container member 40 will be described. As shown in FIG. 5, the second container member 40 has a second surface portion 41, a second side wall portion 42 provided around the second surface portion 41, and a second inner wall portion 50 provided inside the second side wall portion 42. Among these, the second surface portion 41 has a rectangular shape in plan view. Note that the shape of the second surface portion 41 is substantially the same as the shape of the first surface portion 21. This second surface portion 41 is located on the opposite side of the first surface portion 21 in a state where the first container member 20 and the second container member 40 are assembled. And a space for storing the chip component is configured by the first surface portion 21, the second surface portion 41, and the side wall surface 12 (see FIG. 1).

[0042] The thickness (Z direction distance) of the second surface portion 41 may be 0.5 mm or more and 2 mm or less. When the thickness is 0.5 mm or more, it is possible to suppress a decrease in the rigidity of the second container member 40. When the thickness is 2 mm or less, it is possible to suppress a decrease in the transparency of the second surface portion 41.

[0043] The second side wall portion 42 is formed along the periphery of the second surface portion 41 so as to protrude from the second surface portion 41 toward the first container member 20 (the negative Z-direction side). As described above, the second side wall portion 42 and the first side wall portion 22 of the first container member 20 form the side wall surface 12 of the main body 10.

[0044] The second side wall portion 42 includes a first long side portion 42a, a second long side portion 42b, a first short side portion 42c, and a second short side portion 42d. Of these, the first long side portion 42a and the second long side portion 42b face each other and extend along the longitudinal direction (X direction) of the second surface portion 41. On the other hand, the first short side portion 42c and the second short side portion 42d face each other and extend along the width direction (Y direction) of the second surface portion 41. In addition, the first short side portion 42c and the second short side portion 42d extend between the first long side portion 42a and the second long side portion 42b.

[0045] The second side wall portion 42 has a fourth through portion 45 formed therein, which penetrates the second side wall portion 42 in the thickness direction. The fourth through portion 45 constitutes the main body opening 11 together with the first through portion 25 of the first container member 20. That is, as described above, the fourth through portion 45 corresponds to the first through portion 25 of the first container member 20, and the main body opening 11 of the main body 10 is formed by the fourth through portion 45 and the first through portion 25. This fourth through portion 45 is formed in the first short side portion 42c.

[0046] A fifth through-hole portion 46 that penetrates the second side wall portion 42 in the thickness direction is formed in a portion of the second side wall portion 42 different from the fourth through-hole portion 45. As described above, the fifth through-hole portion 46 corresponds to the second through-hole portion 26 of the first container member 20, and the fifth through-hole portion 46 and the second through-hole portion 26 form the operation section 13 of the main body 10. This fifth through-hole portion 46 is formed in the first long side portion 42a.

[0047] The second inner wall portion 50 is formed to protrude from the second surface portion 41 toward the first container member 20 (the negative side in the Z direction). In this embodiment, the second inner wall portion 50 includes a third guide member 51a, a fourth guide member 51b, a second slider guide member 53, a fourth shutter guide member 58a, a fifth shutter guide member 58b, and a sixth shutter guide member 58c, which will be described later. In the following description, the third guide member 51a, the fourth guide member 51b, the second slider guide member 53, the fourth shutter guide member 58a, the fifth shutter guide member 58b, and the sixth shutter guide member 58c will also be collectively referred to simply as the second inner wall portion 50.

[0048] As shown in FIG. 5, a third guide member 51a is provided inside the second container member 40, extending from the vicinity of the fourth penetrating portion 45 to the vicinity of the first long side portion 42a of the second side wall portion 42. A fourth guide member 51b is provided inside the second container member 40, extending from the vicinity of the fourth penetrating portion 45 to the vicinity of the second long side portion 42b of the second side wall portion 42. The third guide member 51a and the fourth guide member 51b are formed of rod-shaped members extending at an angle with respect to the longitudinal direction (X direction) of the second surface portion 41. The third guide member 51a is provided at a position corresponding to the first guide member 31a of the first container member 20, and is joined to the first guide member 31a. The fourth guide member 51b is provided at a position corresponding to the second guide member 31b of the first container member 20, and is joined to the second guide member 31b.

[0049] Further, a second slider guide member 53 that guides the movement of the slider 70 is provided inside the second container member 40. This second slider guide member 53 is composed of a plate-shaped member extending from the third guide member 51a along the first long side portion 42a.

[0050] Furthermore, a fourth shutter guide member 58a and a fifth shutter guide member 58b are provided in the vicinity of the first short side portion 42c on the inside of the second container member 40. A sixth shutter guide member 58c is provided in the vicinity of the first long side portion 42a on the inside of the second container member 40. The fourth shutter guide member 58a is made of a plate-like member extending from the third guide member 51a along the first short side portion 42c. The fifth shutter guide member 58b is made of a plate-like member extending from the fourth guide member 51b along the first short side portion 42c. The sixth shutter guide member 58c is made of a plate-like member extending from the fourth shutter guide member 58a along the first long side portion 42a. In this way, by providing the fourth shutter guide member 58a, the fifth shutter guide member 58b, and the sixth shutter guide member 58c, the shutter 60 can move smoothly.

[0051] 5 to 7, in this embodiment, the second sidewall portion 42 includes a second low sidewall portion 47 joined to the first high sidewall portion 28 of the first sidewall portion 22, and a second high sidewall portion 48 that is higher (Z-direction distance) than the second low sidewall portion 47 and joined to the first low sidewall portion 27 of the first sidewall portion 22. In the illustrated example, the second low sidewall portion 47 is formed in a portion other than both sides of the fourth penetrating portion 45. In addition, both sides of the fourth penetrating portion 45 are the second high sidewall portions 48.

[0052] The height H3 (Z-direction distance, see FIG. 6) of the second lower side wall portion 47 may be the same as the height h3 (Z-direction distance, see FIG. 7) of a second lower inner wall portion 54 of the second inner wall portion 50, which will be described later. This allows the first side wall portion 22 and the first inner wall portion 30 of the first container member 20 and the second side wall portion 42 and the second inner wall portion 50 of the second container member 40 to come into contact with each other when the first container member 20 and the second container member 40 are joined together, as will be described later. This makes it possible to prevent a decrease in the adhesive strength between the first container member 20 and the second container member 40.

[0053] The height H3 of the second low side wall portion 47 may be 0.3 mm or more and 4.0 mm or less. When the height H3 is 0.3 mm or more, it is possible to suppress the occurrence of deformation such as warping in the second container member 40. Furthermore, when the height H3 is 0.3 mm or more, it is easy to join the first high side wall portion 28 and the second low side wall portion 47 described above. Furthermore, when the height H3 is 4.0 mm or less, even if the distance d3 (X-direction distance, see FIG. 6) between the second low side wall portion 47 and the second high inner wall portion 55 described later is short, the second container member 40 can be easily manufactured. The distance d3 may be 0.2 mm or more and 0.5 mm or less.

[0054] The height H4 (Z-direction distance, see FIG. 7) of the second high side wall portion 48 may be the same as the height h4 (Z-direction distance, see FIG. 6) of a second high inner wall portion 55 of the second inner wall portion 50, which will be described later. This allows the first side wall portion 22 and the first inner wall portion 30 of the first container member 20 and the second side wall portion 42 and the second inner wall portion 50 of the second container member 40 to come into contact with each other when the first container member 20 and the second container member 40 are joined together, as will be described later. This makes it possible to prevent a decrease in the adhesive strength between the first container member 20 and the second container member 40.

[0055] The height H4 of the second high side wall portion 48 may be 3.5 mm or more and 7.5 mm or less. By setting the height H4 to 3.5 mm or more, the height H1 of the first low side wall portion 27 joined to the second high side wall portion 48 can be reduced. Therefore, even if the distance d1 between the first low side wall portion 27 and the first high inner wall portion 35 is short, the first container member 20 can be easily manufactured. Furthermore, by setting the height H4 to 7.5 mm or less, the height H1 of the first low side wall portion 27 can be increased, and deformation such as warping of the first container member 20 can be suppressed. The distance d4 may be 0.2 mm or more and 0.5 mm or less.

[0056] 5 to 7, the second inner wall portion 50 includes a second low inner wall portion 54 joined to the first high inner wall portion 35 of the first inner wall portion 30, and a second high inner wall portion 55 that is higher (Z-direction distance) than the second low inner wall portion 54 and joined to the first low inner wall portion 34 of the first inner wall portion 30. In the illustrated example, the third guide member 51a, the fourth guide member 51b, the second slider guide member 53, a part of the fourth shutter guide member 58a, and the fifth shutter guide member 58b of the second inner wall portion 50 form the second low inner wall portion 54. Also, the other part of the fourth shutter guide member 58a and the sixth shutter guide member 58c of the second inner wall portion 50 form the second high inner wall portion 55.

[0057] The height h3 of the second low inner wall portion 54 may be 0.3 mm or more and 4.0 mm or less. When the height h3 is 0.3 mm or more, it is possible to suppress the occurrence of deformation such as warping in the second container member 40. Furthermore, when the height h3 is 0.3 mm or more, it becomes easier to join the above-mentioned first high inner wall portion 35 and the second low inner wall portion 54. Furthermore, when the height h3 is 4.0 mm or less, it is possible to easily manufacture the first container member 20 even when the distance d4 between the second low inner wall portion 54 and the second high side wall portion 48 is short.

[0058] The height h4 of the second highest inner wall portion 55 may be 3.5 mm or more and 7.5 mm or less. Since the height h4 is 3.5 mm or more, the height h1 of the first lowest inner wall portion 34 joined to the second highest inner wall portion 55 can be made lower. Therefore, even when the distance d2 between the first highest side wall portion 28 and the first lowest inner wall portion 34 is short, the first container member 20 can be easily manufactured. Further, since the height h4 is 7.5 mm or less, the height h1 of the first lowest inner wall portion 34 can be made higher, and the occurrence of deformation such as warping in the first container member 20 can be suppressed.

[0059] In such a second container member 40, the total height of the height H3 of the second lowest side wall portion 47 and the height H6 (Z-direction distance, see FIGS. 6 and 7) of the second surface portion 41, and the total height of the height h3 of the second lowest inner wall portion 54 and the height H6 of the second surface portion 41 may be less than half of the height H of the component container 10A. That is, the following formulas (5) and (6) may be satisfied. H3 + H6 < H / 2 ··· Formula (5) h3 + H6 < H / 2 ··· Formula (6) H: Height of the component container 10A H3: Height of the second lowest side wall portion 47 H6: Height of the second surface portion 41 h3: Height of the second lowest inner wall portion 54

[0060] Further, the total height of the height H4 of the second highest side wall portion 48 and the height H6 of the second surface portion 41, and the total height of the height h4 of the second highest inner wall portion 55 and the height H6 of the second surface portion 41 may be higher than half of the height H of the component container 10A. That is, the following formulas (7) and (8) may be satisfied. H4 + H6 > H / 2 ··· Formula (7) h4 + H6 > H / 2 ··· Formula (8) H: Height of the component container 10A H4: Height of the second highest side wall portion 48 H6: Height of the second surface portion 41 h4: Height of the second highest inner wall portion 55

[0061] The first container member 20 and the second container member 40 are bonded to each other. Specifically, the first low side wall portion 27 and the second high side wall portion 48 are bonded to each other, the first low inner wall portion 34 and the second high inner wall portion 55 are bonded to each other, the first high side wall portion 28 and the second low side wall portion 47 are bonded to each other, and the first high inner wall portion 35 and the second low inner wall portion 54 are bonded to each other (see Figs. 11 and 12 described later). Therefore, the total height of the height H1 of the first low side wall portion 27 and the height H4 of the second high side wall portion 48, the total height of the height h1 of the first low inner wall portion 34 and the height h4 of the second high inner wall portion 55, the total height of the height H2 of the first high side wall portion 28 and the height H3 of the second low side wall portion 47, and the total height of the height h2 of the first high inner wall portion 35 and the height h3 of the second low inner wall portion 54 are equal to each other. That is, the following formula (9) is satisfied. H1+H4=h1+h4=H2+H3=h2+h3...Equation (9) H1: Height of the first lower side wall portion 27 H2: Height of the first high side wall portion 28 H3: Height of the second lower side wall portion 47 H4: Height of the second high side wall portion 48 h1: Height of the first lower inner wall portion 34 h2: Height of the first high inner wall portion 35 h3: Height of the second lower inner wall portion 54 h4: Height of the second high inner wall portion 55

[0062] When assembling the first container member 20 and the second container member 40, the first container member 20 and the second container member 40 are joined to each other by, for example, ultrasonic sealing, etc. In this way, the first container member 20 and the second container member 40 are assembled to each other.

[0063] Here, in this embodiment, as described above, the first guide 14 for guiding the movement of the shutter 60 is formed by the first side wall portion 22, the first inner wall portion 30, the second side wall portion 42, and the second inner wall portion 50. In this case, a part of the first guide 14 is formed by the first low side wall portion 27, the second high side wall portion 48, the first high inner wall portion 35, and the second low inner wall portion 54. In addition, the other part of the first guide is formed by the first high side wall portion 28, the second low side wall portion 47, the first low inner wall portion 34, and the second high inner wall portion 55. This makes it possible to easily manufacture the first container member 20 and the second container member 40 even when the above-mentioned distances d1 to d4 are short.

[0064] Next, the shutter 60 will be described with reference to Figs. 8 to 10. The shutter 60 is a member that slidably opens and closes the main body opening 11. The shutter 60 can be in an open position (see Fig. 9) and a closed position (see Fig. 10). As shown in Fig. 9, when the shutter 60 is in the open position, the shutter 60 opens the main body opening 11. That is, when the shutter 60 is in the open position, the main body opening 11 is exposed. On the other hand, as shown in Fig. 10, when the shutter 60 is in the closed position, the shutter 60 closes the main body opening 11. That is, when the shutter 60 is in the closed position, the shutter 60 covers the main body opening 11.

[0065] The shutter 60 is provided inside the main body 10. The shutter 60 is configured to move along the first guide 14.

[0066] In this embodiment, the tip of the shutter 60 is curved. That is, the corners of the tip of the shutter 60 are curved in an arch shape. In other words, the corners of the tip of the shutter 60 are rounded, and the tip of the shutter 60 does not include a portion that extends straight in the width direction (Z direction) of the shutter 60. In this case, the tip of the shutter 60 may include a plurality of portions curved in an arch shape. By the curved tip of the shutter 60, it is possible to prevent the tip of the shutter 60 from getting caught on the edge of the main body opening 11 (i.e., the second shutter guide member 38b or the fifth shutter guide member 58b) when the shutter 60 moves. Therefore, the shutter 60 can move smoothly. The tip of the shutter 60 refers to the end portion on the front side in the moving direction when the shutter 60 moves from the open position to the closed position. In other words, the tip of the shutter 60 refers to the end portion of the longitudinal direction of the shutter 60 to which the slider 70 is not attached.

[0067] Furthermore, in the vicinity of the tip of the shutter 60, the width (distance in the Z direction) of the shutter 60 gradually narrows as it approaches the tip. This effectively prevents the tip of the shutter 60 from getting caught on the edge of the main body opening 11 when the shutter 60 moves.

[0068] A recess 61 may be formed in the center of the width direction (Z direction) of the shutter 60 at the tip of the shutter 60. This recess 61 is recessed towards the rear end side of the shutter 60. By forming the recess 61 in the center of the width direction of the shutter 60 in this manner, it is possible to prevent the center of the width direction of the shutter 60 from warping up when the shutter 60 is moved. This makes it possible to more effectively prevent the tip of the shutter 60 from getting caught on the edge of the main body opening 11. As a result, the shutter 60 can move even more smoothly.

[0069] The recess 61 may have an arc shape. Furthermore, portions located on both sides of the recess 61 in the width direction of the shutter 60 may have an arc shape similar to the recess 61. In the illustrated example, the portions located on both sides of the recess 61 are convex toward the tip side of the shutter 60. In this case, the radius and central angle of the arc formed by these portions may be the same as the radius and central angle of the arc formed by the recess 61.

[0070] The depth d of the recess 61 may be 0.2 mm or more and 1.0 mm or less. When the depth d of the recess 61 is 0.2 mm or more, it is possible to more effectively prevent the central portion of the shutter 60 in the width direction from warping up when the shutter 60 is moved. Furthermore, when the depth d of the recess 61 is 1.0 mm or less, it is possible to effectively maintain the rigidity of the tip of the shutter 60.

[0071] The thickness of such a shutter 60 may be, for example, about 0.2 mm.

[0072] Next, the slider 70 will be described with reference to Fig. 8. The slider 70 is a member for sliding the shutter 60. The slider 70 can take an open position (see Fig. 9) and a closed position (see Fig. 10).

[0073] The slider 70 is provided inside the main body 10. The slider 70 is configured to slide along the first slider guide member 33 and the second slider guide member 53 of the main body 10. As shown in Fig. 8, the slider 70 may be provided with a protrusion 71 for preventing slipping.

[0074] Incidentally, an engagement portion (not shown) may be formed on the main body 10 so that the slider 70 is held in the open position or the closed position.

[0075] The material for the first container member 20 and the second container member 40 may be a synthetic resin such as acrylonitrile-butadiene-styrene resin (ABS resin). The first container member 20 and the second container member 40 may be produced by, for example, injection molding. The flexural modulus of ABS resin measured in accordance with ASTM D 790 is about 1400 MPa to 2000 MPa.

[0076] The shutter 60 may be made of a synthetic resin such as polyethylene terephthalate (PET), and may be made of a polyethylene terephthalate film.

[0077] Furthermore, a synthetic resin such as polypropylene (PP) may be used as the material of the slider 70. For example, an injection molding method may be used as a method for producing the slider 70. The flexural modulus of polypropylene measured in accordance with JIS K 7161:2014 is about 900 MPa to 1200 MPa.

[0078] Next, the operation of the present embodiment having the above-mentioned configuration will be described. Here, a method for manufacturing the component container 10A will be described with reference to Figs.

[0079] First, the first container member 20 and the second container member 40 are prepared. The first container member 20 and the second container member 40 may be manufactured by, for example, an injection molding method. In this embodiment, the first side wall portion 22 includes a first low side wall portion 27 and a first high side wall portion 28. The first inner wall portion 30 includes a first low inner wall portion 34 and a first high inner wall portion 35. The second side wall portion 42 includes a second low side wall portion 47 and a second high side wall portion 48. The second inner wall portion 50 includes a second low inner wall portion 54 and a second high inner wall portion 55. This makes it possible to easily manufacture the first container member 20 and the second container member 40 even when the distances d1 to d4 (see FIGS. 3, 4, 6, and 7) are short.

[0080] Next, as shown in Figures 11 and 12, the first container member 20 and the second container member 40 are overlapped. At this time, as shown in Figure 11, the first low side wall portion 27 of the first container member 20 and the second high side wall portion 48 of the second container member 40 come into contact with each other. Furthermore, the first high inner wall portion 35 of the first container member 20 and the second low inner wall portion 54 of the second container member 40 come into contact with each other. Furthermore, as shown in Figure 12, the first high side wall portion 28 of the first container member 20 and the second low side wall portion 47 of the second container member 40 come into contact with each other. Furthermore, the first low inner wall portion 34 of the first container member 20 and the second high inner wall portion 55 of the second container member 40 come into contact with each other.

[0081] Next, a horn of an ultrasonic welding device (not shown) is pressed against the first container member 20 from the negative side in the Z direction to ultrasonically seal the first container member 20 and the second container member 40. In this manner, the component container 10A is obtained.

[0082] Thus, according to this embodiment, the first guide 14 for guiding the movement of the shutter 60 is formed by the first side wall portion 22, the first inner wall portion 30, the second side wall portion 42, and the second inner wall portion 50. The first side wall portion 22 includes a first low side wall portion 27 and a first high side wall portion 28 that is higher than the first low side wall portion 27. The first inner wall portion 30 includes a first low inner wall portion 34 and a first high inner wall portion 35 that is higher than the first low inner wall portion 34. The second side wall portion 42 includes a second low side wall portion 47 that is joined to the first high side wall portion 28, and a second high side wall portion 48 that is higher than the second low side wall portion 47 and is joined to the first low side wall portion 27. Further, the second inner wall portion 50 includes a second low inner wall portion 54 joined to the first high inner wall portion 35, and a second high inner wall portion 55 that is higher than the second low inner wall portion 54 and joined to the first low inner wall portion 34. The first low side wall portion 27, the second high side wall portion 48, the first high inner wall portion 35, and the second low inner wall portion 54 form a part of the first guide 14, and the first high side wall portion 28, the second low side wall portion 47, the first low inner wall portion 34, and the second high inner wall portion 55 form another part of the first guide 14. This makes it possible to easily manufacture the first container member 20 even if the distance d1 between the first low side wall portion 27 and the first high inner wall portion 35 and the distance d2 between the first high side wall portion 28 and the first low inner wall portion 34 are short. In this case, it is possible to suppress the occurrence of a portion with a weakened strength in a mold (not shown) for manufacturing the first container member 20. In particular, the strength of the part of the mold corresponding to the region between the first low side wall portion 27 and the first high inner wall portion 35, or the part corresponding to the region between the first high side wall portion 28 and the first low inner wall portion 34 can be suppressed from being weakened. Furthermore, even if the distance d3 between the second low side wall portion 47 and the second high inner wall portion 55 and the distance d4 between the second high side wall portion 48 and the second low inner wall portion 54 are short, the second container member 40 can be easily manufactured. Even in this case, the mold (not shown) for manufacturing the second container member 40 can be suppressed from having a part with a weakened strength. In particular, the strength of the part of the mold corresponding to the region between the second low side wall portion 47 and the second high inner wall portion 55, or the part corresponding to the region between the second high side wall portion 48 and the second low inner wall portion 54 can be suppressed from being weakened.

[0083] According to this embodiment, the height H1 of the first low side wall portion 27 is the same as the height h1 of the first low inner wall portion 34, and the height H2 of the first high side wall portion 28 is the same as the height h2 of the first high inner wall portion 35. Similarly, the height H3 of the second low side wall portion 47 is the same as the height h3 of the second low inner wall portion 54, and the height H4 of the second high side wall portion 48 is the same as the height h4 of the second high inner wall portion 55. As a result, when the first container member 20 and the second container member 40 are joined to each other, the first low side wall portion 27 and the second high side wall portion 48, the first high inner wall portion 35 and the second low inner wall portion 54, the first high side wall portion 28 and the second low side wall portion 47, and the first low inner wall portion 34 and the second high inner wall portion 55 are in contact with each other, respectively. This makes it possible to suppress a decrease in the adhesive strength between the first container member 20 and the second container member 40.

[0084] Furthermore, according to the present embodiment, the first inner wall portion 30 and the second inner wall portion 50 form the second guide 15 that guides the movement of the chip component. This makes it possible to easily guide the chip component to the main body opening 11.

[0085] It is also possible to combine the multiple components disclosed in the above embodiment and modified examples as necessary, or to delete some of the components disclosed in the above embodiment and modified examples. [Explanation of symbols]
