[0015] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. FIGS. 1 to 9 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.
[0016] 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.
[0017] 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.
[0018] 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.
[0019] 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 and a first side wall portion 22 provided around the first surface portion 21. 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.
[0020] 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.
[0021] 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.
[0022] 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.
[0023] 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.
[0024] 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.
[0025] The height (Z-direction distance) of the first side wall portion 22 is approximately constant in the circumferential direction, except for the first through portion 25 and the second through portion .
[0026] As shown in FIG. 2, a first guide member (first inner wall portion) 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 (first inner wall portion) 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-shaped members extending at an angle with respect to the longitudinal direction (X direction) of the first surface portion 21. In this way, by providing the first guide member 31a and the second guide member 31b, the chip component can be easily guided to the main body opening 11.
[0027] Further, a first slider guide member (first inner wall portion) 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.
[0028] Furthermore, inside the first container member 20, a first shutter guide member (first inner wall portion) 38a and a second shutter guide member (first inner wall portion) 38b are provided near the first short side portion 22c. Inside the first container member 20, a third shutter guide member (first inner wall portion) 38c is provided 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 case, the distance (X-direction distance) between the first short side portion 22c and the first and second shutter guide members 38a, 38b may be, for example, less than twice the thickness of the shutter 60. For example, when the thickness of the shutter 60 is 0.2 mm, the distance may be approximately 0.4 mm. Similarly, the distance (Y-direction distance) between the first long side portion 22a and the third shutter guide member 38c may be, for example, less than twice the thickness of the shutter 60.
[0029] The above-mentioned first guide member 31a, second guide member 31b, first slider guide member 33, first shutter guide member 38a, second shutter guide member 38b and third shutter guide member 38c are provided inside the first sidewall portion 22 and protrude from the first surface portion 21 toward the second container member 40 (the positive side in the Z direction). In the following description, the first guide member 31a, second guide member 31b, first slider guide member 33, first shutter guide member 38a, second shutter guide member 38b and third shutter guide member 38c are also collectively referred to simply as the first inner wall portion 30.
[0030] Here, in this embodiment, as shown in FIG. 3, the first sidewall portion 22 includes a first tip surface 27 facing the second sidewall portion 42, and a first protruding surface 28 located outside the first tip surface 27 and located closer to the second surface portion 41 side (the positive side in the Z direction) than the first tip surface 27. Of these, the first tip surface 27 is a surface facing a second protruding surface 48 of the second container member 40, which will be described later. Also, the first protruding surface 28 is a surface facing a second tip surface 47 of the second container member 40, which will be described later. A step is formed between the first tip surface 27 and the first protruding surface 28. In this way, by forming a step between the first tip surface 27 and the first protruding surface 28, it is possible to prevent a part of a first protrusion 29, which will be described later, from being mixed into the inside of the component container 10A when the first container member 20 and the second container member 40 are joined to each other by ultrasonic sealing. In order to clarify the drawing, the first tip surface 27, the first protruding surface 28, the third tip surface 34 described later, and the third protruding surface 35 described later are omitted in FIG. 2 described above.
[0031] The distance h1 (Z-direction distance, see FIG. 3) between the first tip surface 27 and the first protruding surface 28 may be 0.3 mm or more and 1.0 mm or less. When the distance h1 is 0.3 mm or more, it is possible to more effectively prevent a part of the first protrusion 29 described later from being mixed into the inside of the component container 10A when the first container member 20 and the second container member 40 are joined together. Furthermore, when the distance h1 is 1.0 mm or less, it is possible to prevent the distance h1 between the first tip surface 27 and the first protruding surface 28 from becoming too long. Therefore, when the horn of an ultrasonic welding device (not shown) is pressed against the first container member 20 from the negative side in the Z direction, the energy during ultrasonic sealing can be efficiently applied to the first protruding surface 28. In addition, since the distance h1 between the first tip surface 27 and the first protruding surface 28 can be prevented from becoming too long, a decrease in the strength of the portion of the first side wall portion 22 between the first tip surface 27 and the first protruding surface 28 can be prevented.
[0032] Further, a first protruding portion 29 is formed on the first protruding surface 28, protruding from the first protruding surface 28 toward a side (positive side in the Z direction) toward a second tip surface 47 (described later) of the second container member 40. This first protruding portion 29 plays a role as a director for efficiently applying energy during ultrasonic sealing.
[0033] The first protrusion 29 is located toward the inside of the first protruding surface 28. This can prevent a portion of the first protrusion 29 from protruding outside the component container 10A when the first container member 20 and the second container member 40 are joined together. Furthermore, when the first protrusion 29 is located toward the inside of the first protruding surface 28, the first protrusion 29 can be located at approximately the center in the thickness direction of the first side wall portion 22. This allows energy to be efficiently transmitted to the first protrusion 29 during ultrasonic sealing.
[0034] The height hp1 (Z-direction distance, see FIG. 3) of such a first protrusion 29 may be 0.2 mm or more and 0.5 mm or less. When the height hp1 is 0.2 mm or more, the amount of the first protrusion 29 that melts can be increased. This increases the adhesive strength between the first protruding surface 28 and the second tip surface 47. Furthermore, when the height hp1 is 0.5 mm or less, it is possible to effectively prevent a part of the first protrusion 29 from protruding outside the component container 10A when the first container member 20 and the second container member 40 are joined together.
[0035] In this embodiment, the height H1 (distance in the Z direction, see FIG. 3) of the first side wall portion 22 may be lower than the height H2 (distance in the Z direction, see FIG. 5) of the second side wall portion 42. This allows the energy during ultrasonic sealing to be applied efficiently to the first protruding surface 28 when the horn of the ultrasonic welding device is pressed against the first container member 20 from the negative side in the Z direction.
[0036] The height H1 of the first sidewall portion 22 may be 0.6 mm or more and 3.0 mm or less. When the height H1 of the first sidewall portion 22 is 0.6 mm or more, the rigidity of the first container member 20 can be increased, and the occurrence of warping in the first surface portion 21 can be effectively suppressed. Furthermore, when the height H1 of the first sidewall portion 22 is 3.0 mm or less, the energy during ultrasonic sealing can be applied more efficiently to the first protruding surface 28 when the horn of an ultrasonic welding device is pressed against the first container member 20 from the negative side in the Z direction.
[0037] As shown in FIG. 3, the first inner wall portion 30 includes a third tip surface 34 facing the second inner wall portion 50 described later, and a third protruding surface 35 located outside the third tip surface 34 and located closer to the second surface portion 41 side (positive side in the Z direction) than the third tip surface 34. Of these, the third tip surface 34 faces a fourth protruding surface 55 described later of the second container member 40. The third protruding surface 35 faces a fourth tip surface 54 described later of the second container member 40. A step is formed between the third tip surface 34 and the third protruding surface 35. By forming a step between the third tip surface 34 and the third protruding surface 35 in this way, when the first container member 20 and the second container member 40 are joined to each other by ultrasonic sealing, it is possible to prevent a part of the second protrusion 36 described later from entering a space in the component container 10A in which chip components are stored.
[0038] The distance h2 (Z-direction distance, see FIG. 3) between the third tip surface 34 and the third protruding surface 35 may be 0.3 mm or more and 1.0 mm or less. When the distance h2 is 0.3 mm or more, it is possible to more effectively prevent a part of the second protrusion 36 described later from being mixed into the space in the component container 10A in which the chip components are stored when the first container member 20 and the second container member 40 are joined together. In addition, when the distance h2 is 1.0 mm or less, it is possible to prevent the distance h2 between the third tip surface 34 and the third protruding surface 35 from becoming too long. Therefore, when the horn of the ultrasonic welding device (not shown) is pressed against the first container member 20 from the negative side in the Z direction, the energy during ultrasonic sealing can be efficiently applied to the third protruding surface 35. In addition, since the distance h2 between the third tip surface 34 and the third protruding surface 35 can be prevented from becoming too long, a decrease in the strength of the portion of the first inner wall portion 30 between the third tip surface 34 and the third protruding surface 35 can be prevented.
[0039] Further, a second protrusion 36 is formed on the third protruding surface 35, protruding from the third protruding surface 35 toward a side (positive side in the Z direction) toward a fourth tip surface 54 (described later) of the second container member 40. This second protrusion 36 plays a role as a director for efficiently applying energy during ultrasonic sealing.
[0040] The second protrusion 36 is located toward the inside of the third protruding surface 35. This makes it possible to prevent a part of the second protrusion 36 from protruding outside the space inside the component container 10A in which the chip components are stored when the first container member 20 and the second container member 40 are joined together. Furthermore, when the second protrusion 36 is located toward the inside of the third protruding surface 35, the second protrusion 36 can be located at approximately the center in the thickness direction of the first side wall portion 22. This makes it possible to efficiently transmit energy during ultrasonic sealing to the second protrusion 36.
[0041] The height hp2 (Z-direction distance, see FIG. 3) of such a second protrusion 36 may be 0.2 mm or more and 0.5 mm or less. When the height hp2 is 0.2 mm or more, the amount of the second protrusion 36 that melts can be increased. This increases the adhesive strength between the third protruding surface 35 and the fourth tip surface 54. Furthermore, when the height hp2 is 0.5 mm or less, it is possible to effectively prevent a part of the second protrusion 36 from protruding outside the space inside the component container 10A in which the chip components are stored when the first container member 20 and the second container member 40 are joined together.
[0042] In this embodiment, the height H3 (distance in the Z direction, see FIG. 3) of the first inner wall portion 30 may be lower than the height H4 (distance in the Z direction, see FIG. 5) of the second inner wall portion 50 described later. This allows the energy during ultrasonic sealing to be applied efficiently to the third protruding surface 35 when the horn of the ultrasonic welding device is pressed against the first container member 20 from the negative side in the Z direction.
[0043] The height H3 of the first inner wall portion 30 may be 0.6 mm or more and 3.0 mm or less. When the height H3 of the first inner wall portion 30 is 0.6 mm or more, the rigidity of the first container member 20 can be increased, and the occurrence of warping in the first surface portion 21 can be effectively suppressed. Furthermore, when the height H3 of the first inner wall portion 30 is 3.0 mm or less, the energy during ultrasonic sealing can be applied more efficiently to the third protruding surface 35 when the horn of an ultrasonic welding device is pressed against the first container member 20 from the negative side in the Z direction.
[0044] Next, the second container member 40 will be described. As shown in FIG. 4, the second container member 40 has a second surface portion 41 and a second side wall portion 42 provided around the second surface portion 41. Of these, the second surface portion 41 has a rectangular shape in a plan view. 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 to the first surface portion 21 when the first container member 20 and the second container member 40 are assembled. The first surface portion 21, the second surface portion 41, and the side wall surface 12 (see FIG. 1) form a space for storing chip components.
[0045] 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.
[0046] 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.
[0047] 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.
[0048] 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.
[0049] 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.
[0050] The height (Z-direction distance) of the second side wall portion 42 is approximately constant in the circumferential direction, except for the fourth through-portion 45 and the fifth through-portion 46.
[0051] As shown in FIG. 4, a third guide member (second inner wall portion) 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 (second inner wall portion) 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 plate-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. Such a guide member may be provided on only one of the first container member 20 and the second container member 40.
[0052] Further, a second slider guide member (second inner wall portion) 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.
[0053] Furthermore, a fourth shutter guide member (second inner wall portion) 58a and a fifth shutter guide member (second inner wall portion) 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 (second inner wall portion) 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. In this case, the distance (X-direction distance) between the first short side portion 42c and the fourth and fifth shutter guide members 58a and 58b may be, for example, less than twice the thickness of the shutter 60. For example, when the thickness of the shutter 60 is 0.2 mm, the distance may be approximately 0.4 mm. Similarly, the distance (Y-direction distance) between the first long side portion 42a and the sixth shutter guide member 58c may be, for example, less than twice the thickness of the shutter 60.
[0054] The above-mentioned third guide member 51a, fourth guide member 51b, second slider guide member 53, fourth shutter guide member 58a, fifth shutter guide member 58b and sixth shutter guide member 58c are provided inside the second sidewall portion 42 and protrude from the second surface portion 41 toward the first container member 20 (negative side in the Z direction). In the following description, the third guide member 51a, fourth guide member 51b, second slider guide member 53, fourth shutter guide member 58a, fifth shutter guide member 58b and sixth shutter guide member 58c are also collectively referred to simply as the second inner wall portion 50.
[0055] Here, in this embodiment, as shown in FIG. 5, the second side wall portion 42 includes a second tip surface 47 facing the first protruding surface 28 described above, and a second protruding surface 48 located inside the second tip surface 47 and located on the first surface portion 21 side (Z direction negative side) from the second tip surface 47. Of these, the second protruding surface 48 is a surface facing the first tip surface 27 of the first container member 20. A step is formed between the second tip surface 47 and the second protruding surface 48. By forming a step between the second tip surface 47 and the second protruding surface 48 in this way, when the first container member 20 and the second container member 40 are joined to each other by ultrasonic sealing, it is possible to suppress a part of the first protrusion 29 described above from being mixed into the inside of the component container 10A. Note that, in order to clarify the drawing, the second tip surface 47, the second protruding surface 48, a fourth tip surface 54 described later, and a fourth protruding surface 55 described later are omitted from FIG. 4 described above.
[0056] The distance h3 (Z-direction distance, see FIG. 5) between the second tip surface 47 and the second protruding surface 48 may be 0.3 mm or more and 1.0 mm or less. When the distance h3 is 0.3 mm or more, it is possible to more effectively prevent a part of the first protrusion 29 from being mixed into the component container 10A when the first container member 20 and the second container member 40 are joined together. In addition, when the distance h3 is 1.0 mm or less, it is possible to prevent the distance h3 between the second tip surface 47 and the second protruding surface 48 from becoming too long. Therefore, when the horn of an ultrasonic welding device (not shown) is pressed against the first container member 20 from the negative side in the Z direction, the energy during ultrasonic sealing can be efficiently applied to the second tip surface 47. In addition, since the distance h3 between the second tip surface 47 and the second protruding surface 48 can be prevented from becoming too long, a decrease in the strength of the portion of the second side wall portion 42 between the second tip surface 47 and the second protruding surface 48 can be prevented.
[0057] The height H2 (see FIG. 5) of such a second side wall portion 42 may be greater than the height H1 of the first side wall portion 22.
[0058] 5, the second inner wall portion 50 includes a fourth tip surface 54 facing the third protruding surface 35 described above, and a fourth protruding surface 55 located inside the fourth tip surface 54 and located closer to the first surface portion 21 side (Z direction minus side) than the fourth tip surface 54. Of these, the fourth protruding surface 55 is a surface facing the third tip surface 34 of the first container member 20. A step is formed between the fourth tip surface 54 and the fourth protruding surface 55. By forming a step between the fourth tip surface 54 and the fourth protruding surface 55 in this way, when the first container member 20 and the second container member 40 are joined to each other by ultrasonic sealing, it is possible to prevent a part of the second protrusion 36 described above from entering the space in the component container 10A in which the chip components are stored.
[0059] The distance h4 (Z-direction distance, see FIG. 5) between the fourth tip surface 54 and the fourth protruding surface 55 may be 0.3 mm or more and 1.0 mm or less. When the distance h4 is 0.3 mm or more, it is possible to more effectively prevent a part of the second protrusion 36 from being mixed into the space in the component container 10A in which the chip components are stored when the first container member 20 and the second container member 40 are joined together. In addition, when the distance h4 is 1.0 mm or less, it is possible to prevent the distance h4 between the fourth tip surface 54 and the fourth protruding surface 55 from becoming too long. Therefore, when the horn of an ultrasonic welding device (not shown) is pressed against the first container member 20 from the negative side in the Z direction, the energy during ultrasonic sealing can be efficiently applied to the fourth tip surface 54. In addition, since the distance h4 between the fourth end surface 54 and the fourth protruding surface 55 can be prevented from becoming too long, a decrease in the strength of the portion of the second inner wall portion 50 between the fourth end surface 54 and the fourth protruding surface 55 can be prevented.
[0060] The height H4 (see FIG. 5) of such a second inner wall portion 50 may be greater than the height H3 of the first inner wall portion 30.
[0061] Such a first container member 20 and a second container member 40 are bonded to each other. In this case, the height H1 of the first side wall portion 22 may be equal to the height H3 of the first inner wall portion 30. Also, the height H2 of the second side wall portion 42 may be equal to the height H4 of the second inner wall portion 50. Also, the distance h1 between the first tip surface 27 and the first protruding surface 28 may be equal to the distance h3 between the second tip surface 47 and the second protruding surface 48. Furthermore, the distance h2 between the third tip surface 34 and the third protruding surface 35 may be equal to the distance h4 between the fourth tip surface 54 and the fourth protruding surface 55. 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 or the like. As a result, the first container member 20 and the second container member 40 are assembled to each other.
[0062] Next, the shutter 60 will be described with reference to Figs. 6 to 8. 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. 7) and a closed position (see Fig. 8). As shown in Fig. 7, 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. 8, 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.
[0063] The shutter 60 is provided inside the main body 10. The shutter 60 is configured to move along the first shutter guide member 38a, the second shutter guide member 38b, the third shutter guide member 38c, the fourth shutter guide member 58a, the fifth shutter guide member 58b, and the sixth shutter guide member 58c of the main body 10.
[0064] 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.
[0065] 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.
[0066] 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.
[0067] 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.
[0068] 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.
[0069] The thickness of such a shutter 60 may be, for example, about 0.2 mm.
[0070] Next, the slider 70 will be described with reference to Fig. 6. The slider 70 is a member for sliding the shutter 60. The slider 70 can take an open position (see Fig. 7) and a closed position (see Fig. 8).
[0071] 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. 6, the slider 70 may be provided with a protrusion 71 for preventing slipping.
[0072] 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.
[0073] 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.
[0074] The shutter 60 may be made of a synthetic resin such as polyethylene terephthalate (PET), and may be made of a polyethylene terephthalate film.
[0075] 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.
[0076] 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.
[0077] First, the first container member 20 and the second container member 40 are prepared.
[0078] 9, the first container member 20 and the second container member 40 are placed on top of each other. At this time, the first protrusion 29 formed on the first protruding surface 28 of the first container member 20 and the second tip surface 47 of the second container member 40 come into contact with each other. In addition, the second protrusion 36 formed on the third protruding surface 35 of the first container member 20 and the fourth tip surface 54 of the second container member 40 come into contact with each other.
[0079] In contrast, the first protruding surface 28 of the first container member 20 and the second tip surface 47 of the second container member 40 do not contact each other. In this case, a gap is formed between the first protruding surface 28 and the second tip surface 47. Here, during ultrasonic sealing, the first protrusion 29 melts due to the energy generated during ultrasonic sealing. At this time, since a gap is formed between the first protruding surface 28 and the second tip surface 47, the first protrusion 29 melts so as to fill the gap. This makes it possible to prevent the first protrusion 29, which has melted during ultrasonic sealing, from protruding onto the outer surface of the first container member 20.
[0080] Moreover, the first tip surface 27 of the first container member 20 and the second protruding surface 48 of the second container member 40 do not contact each other. In this case, a gap is formed between the first tip surface 27 and the second protruding surface 48. In this case, the distance h5 (Z direction distance) between the first tip surface 27 and the second protruding surface 48 may be 0.05 mm or more and 0.2 mm or less. When the distance h5 is 0.05 mm or more, the first container member 20 and the second container member 40 can be joined to each other without preventing the melting of the first protrusion 29. When the distance h5 is 0.2 mm or less, the distance between the first tip surface 27 and the second protruding surface 48 can be 0.05 mm or less after the first container member 20 and the second container member 40 are joined to each other. Therefore, it is possible to prevent the chip component from getting stuck between the first tip surface 27 and the second protruding surface 48.
[0081] Also, the third protruding surface 35 of the first container member 20 and the fourth tip surface 54 of the second container member 40 do not contact each other. In this case, a gap is formed between the third protruding surface 35 and the fourth tip surface 54. Even in this case, the second protrusion 36 melts so as to fill the gap due to the energy generated during ultrasonic sealing. This makes it possible to prevent the second protrusion 36, which melts during ultrasonic sealing, from protruding outside the space inside the component container 10A in which the chip components are stored.
[0082] Also, the third tip surface 34 of the first container member 20 and the fourth protruding surface 55 of the second container member 40 do not contact each other. In this case, a gap is formed between the third tip surface 34 and the fourth protruding surface 55. In this case, the distance h6 (Z direction distance) between the third tip surface 34 and the fourth protruding surface 55 may be 0.05 mm or more and 0.2 mm or less. When the distance h6 is 0.05 mm or more, the first container member 20 and the second container member 40 can be joined to each other without preventing the melting of the second protrusion 36. When the distance h6 is 0.2 mm or less, the distance between the third tip surface 34 and the fourth protruding surface 55 can be 0.05 mm or less after the first container member 20 and the second container member 40 are joined to each other. Therefore, it is possible to prevent the chip component from getting stuck between the third tip surface 34 and the fourth protruding surface 55.
[0083] 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. As a result, as shown in FIG. 10, the first protrusion 29 melts, and the first protruding surface 28 of the first container member 20 and the second tip surface 47 of the second container member 40 are bonded to each other via the first protrusion 29. Here, a step is formed between the second tip surface 47 and the second protruding surface 48 of the second container member 40. Therefore, the step suppresses the movement of the melted first protrusion 29. Therefore, it is possible to suppress the melted first protrusion 29 from being mixed into the interior of the component container 10A.
[0084] Similarly, by ultrasonically sealing the first container member 20 and the second container member 40, as shown in Fig. 10, the second protrusion 36 melts, and the third protruding surface 35 of the first container member 20 and the fourth tip surface 54 of the second container member 40 are bonded to each other via the second protrusion 36. In addition, a step is formed between the fourth tip surface 54 and the fourth protruding surface 55 of the second container member 40. Therefore, the step suppresses the movement of the melted second protrusion 36. Therefore, it is possible to suppress the melted second protrusion 36 from entering the space inside the component container 10A in which the chip components are stored.
[0085] As described above, before the first container member 20 and the second container member 40 are ultrasonically sealed, the distance h5 between the first tip surface 27 and the second protruding surface 48 is 0.2 mm or less. In this case, by ultrasonically sealing the first container member 20 and the second container member 40, the distance between the first tip surface 27 and the second protruding surface 48 becomes 0.05 mm or less. This makes it possible to prevent the chip components stored in the component container 10A from becoming stuck between the first tip surface 27 and the second protruding surface 48. In this case, the first tip surface 27 and the second protruding surface 48 may be in contact with each other or may be bonded to each other.
[0086] Similarly, as described above, before the first container member 20 and the second container member 40 are ultrasonically sealed, the distance h6 between the third tip surface 34 and the fourth protruding surface 55 is 0.2 mm or less. In this case, by ultrasonically sealing the first container member 20 and the second container member 40, the distance between the third tip surface 34 and the fourth protruding surface 55 becomes 0.05 mm or less. This makes it possible to prevent the chip components stored in the component container 10A from becoming stuck between the third tip surface 34 and the fourth protruding surface 55. In this case, the third tip surface 34 and the fourth protruding surface 55 may be in contact with each other or may be bonded to each other.
[0087] In this manner, the component container 10A is obtained.
[0088] Thus, according to this embodiment, the first side wall portion 22 includes a first tip surface 27 facing the second side wall portion 42, and a first protruding surface 28 located outside the first tip surface 27 and located closer to the second surface portion 41 than the first tip surface 27. The second side wall portion 42 includes a second tip surface 47 facing the first protruding surface 28, and a second protruding surface 48 located inside the second tip surface 47 and located closer to the first surface portion 21 than the second tip surface 47. Furthermore, a first protrusion 29 is formed on the first protruding surface 28, which is located closer to the inside and protrudes from the first protruding surface 28 toward the second tip surface 47. As a result, when the first container member 20 and the second container member 40 are joined to each other by ultrasonic sealing, the first protrusion 29 can increase the adhesive strength between the first container member 20 and the second container member 40. Moreover, the first side wall portion 22 includes a first tip surface 27 and a first protruding surface 28, and the second side wall portion 42 includes a second tip surface 47 and a second protruding surface 48. Therefore, when the first container member 20 and the second container member 40 are joined to each other by ultrasonic sealing, it is possible to prevent a part of the first protrusion 29 from being mixed into the component container 10A.
[0089] In addition, the first protrusion 29 is located toward the inside of the first protruding surface 28. This can prevent a portion of the first protrusion 29 from protruding outside the component container 10A when the first container member 20 and the second container member 40 are joined together. In addition, when the first protrusion 29 is located toward the inside of the first protruding surface 28, the first protrusion 29 can be located at approximately the center in the thickness direction of the first side wall portion 22. Therefore, energy during ultrasonic sealing can be efficiently transmitted to the first protrusion 29.
[0090] Furthermore, according to this embodiment, the height H1 of the first side wall portion 22 is lower than the height H2 of the second side wall portion 42. This allows the energy during ultrasonic sealing to be efficiently applied to the first protruding surface 28 when the horn of an ultrasonic welding device is pressed against the first container member 20 from the negative side in the Z direction. This allows the adhesive strength between the first container member 20 and the second container member 40 to be effectively increased.
[0091] According to this embodiment, the first container member 20 further includes a first inner wall portion 30 provided inside the first side wall portion 22 and protruding from the first surface portion 21 toward the second container member 40. The second container member 40 further includes a second inner wall portion 50 provided inside the second side wall portion 42 and protruding from the second surface portion 41 toward the first container member 20. The first inner wall portion 30 further includes a third tip surface 34 facing the second inner wall portion 50, and a third protruding surface 35 located outside the third tip surface 34 and closer to the second surface portion 41 than the third tip surface 34. The second inner wall portion 50 further includes a fourth tip surface 54 facing the third protruding surface 35, and a fourth protruding surface 55 located inside the fourth tip surface 54 and closer to the first surface portion 21 than the fourth tip surface 54. Further, the third protruding surface 35 is formed with a second protruding portion 36 located inward and protruding from the third protruding surface 35 toward the fourth tip surface 54. As a result, when the first container member 20 and the second container member 40 are joined together by ultrasonic sealing, the second protruding portion 36 can increase the adhesive strength between the first container member 20 and the second container member 40. Furthermore, the first inner wall portion 30 includes the third tip surface 34 and the third protruding surface 35, and the second inner wall portion 50 includes the fourth tip surface 54 and the fourth protruding surface 55. Therefore, when the first container member 20 and the second container member 40 are joined together by ultrasonic sealing, it is possible to prevent a part of the second protruding portion 36 from entering the space inside the component container 10A in which the chip components are stored.
[0092] In addition, the second protrusion 36 is located closer to the inside of the third protruding surface 35. This makes it possible to prevent a part of the second protrusion 36 from protruding outside the space inside the component container 10A in which the chip components are stored when the first container member 20 and the second container member 40 are joined together. In addition, when the second protrusion 36 is located closer to the inside of the third protruding surface 35, the second protrusion 36 can be located at approximately the center in the thickness direction of the first side wall portion 22. Therefore, energy during ultrasonic sealing can be efficiently transmitted to the second protrusion 36.
[0093] Furthermore, according to this embodiment, the height H3 of the first inner wall portion 30 is lower than the height H4 of the second inner wall portion 50. This allows the energy during ultrasonic sealing to be applied efficiently to the third protruding surface 35 when the horn of the ultrasonic welding device is pressed against the first container member 20 from the negative side in the Z direction.
[0094] It is also possible to combine the multiple components disclosed in the above embodiment and modified examples as necessary. Alternatively, some of the components disclosed in the above embodiment and modified examples may be deleted. [Explanation of symbols]
