Abstract
Description
[Technical Field]
[0001] The disclosed technology relates to a container. [Background technology]
[0002] Conventionally, containers formed into a box shape by combining multiple resin components have been used. The "foldable container" described in Patent Document 1 is one example. In the container described in this document, a gap is provided between the component that constitutes the side wall and the component immediately below it (the component that constitutes the bottom). This is to allow the side wall to be folded down and to facilitate smooth opening and closing operations. Furthermore, a convex portion is provided on the component that constitutes the bottom, and a convex portion is provided on the component that constitutes the side wall, facing downward. Both convex portions overlap inward and outward. This is to prevent any foreign matter from entering the container through the gap. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-335328 Summary of the Invention [Problem to be solved by the invention]
[0004] The above-mentioned conventional technology has the following problems. Resin components inevitably have some dimensional variation in molded products due to molding technology issues and the characteristics of the raw resin. As a result, the above-mentioned gap may be larger than expected in the design depending on the individual container. In containers with such large gaps, the contents may get trapped in the gap. Depending on the shape of the contents, part of the contents may become wedged in the gap. In this case, it is difficult to remove the wedged contents.
[0005] An object of the present disclosure is to provide a container in which contents are less likely to become caught between constituent parts. [Means for solving the problem]
[0006] In one aspect of the disclosed technology, the container is formed into a box shape by combining multiple resin components, and at the butt joint between a first component and a second component, an overlapping section is provided where the first component and the second component overlap in the inward and outward directions, and a step-shaped portion is formed in a section of the inner wall surface of the second component that is adjacent to the overlapping section, and the step-shaped portion is a portion that forms a step with respect to the inner wall surface of the first component.
[0007] In the container of the above aspect, a stepped portion is disposed adjacent to the overlapping section between the first and second components, thereby preventing a narrow gap from forming between the first and second components near where they butt together, making it difficult for contents to become trapped between the components.
[0008] In the container of the above aspect, it is desirable that in the overlapping section, the second component is located outside the first component, and the stepped portion is a portion recessed outward relative to the inner wall surface of the first component. As a result, a recessed stepped portion exists on the inner surface near the butt point between the first and second components, and the space in the stepped portion prevents the contents from getting caught.
[0009] In a container in which the stepped portion is concave, it is further desirable that the opening width at the inner opening position of the stepped portion be 3 mm or more. When the opening dimension of the stepped portion is large in this way, pinching of the contents is less likely to occur.
[0010] In a container in which the stepped portion is concave, the inner wall surface of the second component preferably has a concave portion that is recessed from the inner wall surface of the first component, a normal portion that protrudes inward from the concave portion, and a boundary portion located between the normal portion and the concave portion, and the stepped portion is preferably composed of the tip surface of the first component, the concave portion, and the boundary portion, and extends in the vertical direction. The space defined in this way in the stepped portion prevents the contents from getting pinched.
[0011] In a container having a concave stepped portion, it is further desirable that the stepped portion has a sloped shape that widens toward the inside. Such a stepped portion shape is also advantageous in preventing the contents from getting caught.
[0012] In any of the above containers, the plurality of components preferably includes components that form the bottom surface of the container and components that form the sidewalls of the container, and at least one of the first and second components preferably forms the sidewalls of the container, and is a movable member that can move relative to the bottom surface of the container and is displaceable between a contact state in which a portion of the first component and a portion of the second component are in contact with each other and a separated state in which the contact points of the first and second components are separated. This prevents the contents from getting caught in the butt points of the components that form the sidewalls of the container.
[0013] In a container in which the stepped portion is formed by a concave portion or the like, it is further preferable that a first opposing surface facing the second component is formed on the outer wall surface of the first component other than the overlapping section, and that a second opposing surface facing the first opposing surface is formed on the second component, with a gap between the first opposing surface and the second opposing surface. This gap allows the first component and the second component to be properly butted together. Furthermore, it is preferable that the opening width at the interior opening of the stepped portion is three or more times the clearance dimension of the gap. Furthermore, it is preferable that the width dimension of the concave portion other than the overlapping section is larger than the clearance dimension of the gap. In this way, the large space dimension even at the rear of the stepped portion more reliably prevents the contents from getting pinched. [Effects of the Invention]
[0014] According to this configuration, a container is provided in which the contents are less likely to become caught between the constituent members. [Brief explanation of the drawings]

[0016] Hereinafter, embodiments embodying the present disclosure will be described in detail with reference to the accompanying drawings. A container 1 according to this embodiment is a roughly rectangular box-shaped container with an open top, as shown in FIG. 1. The container 1 is constructed by combining multiple resin components. The multiple components are three types: a bottom member 2, a short-side wall member 3, and a long-side wall member 4. In the container 1, the bottom member 2 forms the bottom portion, the short-side wall member 3 forms the short-side side wall portion, and the long-side wall member 4 forms the long-side side wall portion. FIG. 2 shows the respective components separated. Each of these components is a molded resin product.
[0017] The short-side wall members 3 and long-side wall members 4 of the container 1 are foldable. As shown in Figure 3, the two short-side wall members 3 are first folded inward, and then the two long-side wall members 4 are also folded inward to achieve the state shown in Figure 4. The long-side wall members 4 are further divided into a fixed member 5 and a movable member 6.
[0018] As shown in Figure 5, the container 1 can be displaced to a state in which only the movable member 6 is tilted outward. The movable member 6 in Figure 5 is in an open state, having moved outward compared to the state in Figure 1. In contrast, the movable member 6 in Figure 1 is in a closed state. More specifically, in the open state, the movable member 6 is tilted outward with its bottom edge 7 as a hinge axis. Therefore, the vertical edge 8 of the movable member 6 and the vertical edge 9 of the fixed member 5 are in a separated state. The movable member 6 can move relative to the bottom surface of the container 1. The movable member 6 can also be completely separated from the fixed member 5, as shown in Figures 6 and 7. Both the fixed member 5 and the movable member 6 are members that form the side walls of the long sides of the container 1.
[0019] The area near the joint between the long-side wall member 4 and the short-side wall member 3 is shown in Figure 8 when viewed from diagonally above the inside. Figure 9 is a view of this area from a slightly different angle. As shown in Figures 8 and 9, a step-shaped portion 10 is formed on the inner surface of the long-side wall member 4 when the movable member 6 is closed, at the joint between the fixed member 5 and the movable member 6. The step-shaped portion 10 will be described with reference to Figures 10 to 12.
[0020] As shown in Figure 10, where the fixed member 5 and the movable member 6 butt together, there is an overlapping section L where the fixed member 5 and the movable member 6 overlap in the inward and outward directions. In the overlapping section L, the movable member 6 is located outside the fixed member 5. The fixed member 5 corresponds to the first component member, and the movable member 6 corresponds to the second component member. In Figure 10, the upper side of the fixed member 5 and the movable member 6 is the outside of the container 1, and the lower side is the inside, i.e., the storage space of the container 1. The stepped portion 10 is adjacent to the overlapping section L. More specifically, when the container 1 is viewed in a plan view, the stepped portion 10 is adjacent to the overlapping section L in the width direction of the long side wall member 4. The stepped portion 10 is on the movable member 6 side of the overlapping section L.
[0021] As shown in Figure 11, the fixed member 5 has an inner wall surface 50, a first convex portion 51, and an outer portion 52. The inner wall surface 50 is the surface of the fixed member 5 that faces the storage space of the container 1. The first convex portion 51 is a portion that is provided in a part of the thickness direction of the fixed member 5 and has a shape that protrudes toward the movable member 6. The first convex portion 51 is formed at a position closer to the inside of the entire thickness of the fixed member 5. The outer portion 52 is the portion of the fixed member 5 that faces the outside of the container 1.
[0022] The fixed member 5 further has a tip surface 53, an outer surface 54, and a first opposing surface 55. The tip surface 53 is the surface at the tip of the first convex portion 51. The tip surface 53 is the most distal surface of the entire fixed member 5 on the movable member 6 side within the range shown in FIG. 10. The outer surface 54 is the outer surface of the first convex portion 51. The first opposing surface 55 is the surface that faces the movable member 6 in a portion that is outer than the first convex portion 51 in the thickness direction.
[0023] As shown in Figure 12, the movable member 6 has a normal portion 60, a concave portion 61, a boundary portion 62, and a second opposing surface 63. The normal portion 60 is the surface of the movable member 6 that faces the storage space of the container 1. The concave portion 61 is a portion that is recessed from the inner wall surface 50 of the fixed member 5. The concave portion 61 is also a portion that is recessed from the normal portion 60. The boundary portion 62 is a portion located between the normal portion 60 and the concave portion 61. The second opposing surface 63 is a surface that faces the fixed member 5 in Figure 10, on the outer side in the thickness direction than the concave portion 61. The normal portion 60 is approximately flush with the inner wall surface 50 of the fixed member 5.
[0024] The normal portion 60, the concave portion 61, and the boundary portion 62 are all inner wall surfaces that face the storage space of the container 1. Among them, the normal portion 60 has the largest area and is the portion other than the stepped portion 10 described above. In FIG. 10, a portion of the concave portion 61 is in contact with the outer surface 54 of the fixed member 5, and only the remaining portion faces the storage space. The portion of the movable member 6 behind the concave portion 61 is called the second convex portion 64. The second convex portion 64 is a portion of the movable member 6 that protrudes toward the fixed member 5 in a range closer to the outside in the thickness direction.
[0025] The overlapping section L in FIG. 10 includes the first convex portion 51 of the fixed member 5 and the second convex portion 64 of the movable member 6. In the overlapping section L, the second convex portion 64 is located outside the first convex portion 51. The outer surface 54 of the first convex portion 51 is in contact with the concave portion 61 of the second convex portion 64. The stepped portion 10 in FIG. 10 is formed by the concave portion 61 and boundary portion 62 of the movable member 6 and the tip surface 53 of the fixed member 5. This forms the stepped portion 10, which is recessed from the inner wall surface 50 of the fixed member 5. The stepped portion 10 extends in the vertical direction as seen in FIGS. 8 and 9. In FIG. 10, the first opposing surface 55 of the fixed member 5 and the second opposing surface 63 of the movable member 6 face each other with a gap C between them.
[0026] In the open state shown in Fig. 5, the movable member 6 is laid down, so that the outer surface 54 of the first convex portion 51 is separated from the inner concave portion 61 of the second convex portion 64. Even in this open state, contents can be placed on the bottom member 2. Thereafter, by standing the movable member 6 upright to return to the closed state shown in Fig. 1, contents can be placed in the storage space of the container 1.
[0027] In this case, the container 1 of this embodiment has the advantage that the contents are less likely to be pinched at the abutting portion between the fixed member 5 and the movable member 6. This is because the aforementioned step-shaped portion 10 is formed at the abutting portion. The presence of the step-shaped portion 10 when in the closed state means that there is a significant space between the tip surface 53 of the fixed member 5 and the boundary portion 62 of the movable member 6, and there is no narrow gap. Therefore, even small or soft contents will not be pinched between the tip surface 53 and the boundary portion 62. If the tip surface 53 and the boundary portion 62 were set to contact or be very close to each other when in the closed state, there would be a risk that the contents would be pinched between the tip surface 53 and the boundary portion 62 when the movable member 6 was closed. However, there is no such risk with the container 1 of this embodiment.
[0028] Even in the container 1 of this embodiment, in the closed state, the outer surface 54 on the outside of the first convex portion 51 and the concave portion 61 on the inside of the second convex portion 64 are in contact within the range of overlapping section L. However, the probability of a contained item becoming trapped here is extremely low. This is because the space between the outer surface 54 and the concave portion 61 is the space beyond the first convex portion 51 when viewed from the contained item stored on the bottom member 2. In fact, the greater advantage is that the contact between the outer surface 54 and the concave portion 61 prevents foreign objects from entering the storage space from the outside.
[0029] The details of the stepped portion 10 will be further explained with reference to Fig. 13. In Fig. 13, there is a location where the first opposing surface 55 and the second opposing surface 63 face each other near the stepped portion 10. It is desirable that the gap C be 1 mm or more. The reason for this is the dimensional tolerance of the fixed member 5 and the movable member 6. Because these are both molded resin products, unless a clearance dimension of that magnitude is provided in the design, it may not be possible to close the movable member 6 depending on the individual product.
[0030] It is preferable that the stepped portion 10 also has a certain degree of dimension. However, the reason for this is to prevent the contents from getting caught, as described above, unlike the gap C. The dimension required for the stepped portion 10 is the dimension in the width direction, which is the dimension in the left-right direction in Figure 13. There are two dimensions for the width direction of the stepped portion 10: the dimension at the internal opening position and the dimension at the external position.
[0031] The dimension at the internal opening position refers to the opening width on the storage space side of the stepped portion 10. In FIG. 13, this refers to the opening width F from the internal end P of the tip surface 53 to the boundary S between the boundary portion 62 and the normal portion 60. The opening width F is preferably 3 mm or more, or preferably three times the gap C or more.
[0032] The dimension at the outer position refers to the width at the rear position of the stepped portion 10, that is, the position closer to the outside of the container. In FIG. 13, this is the width of the portion of the concave portion 61 other than the overlapping section L. In other words, it is the width E from the outer end Q of the tip surface 53 to the boundary R between the concave portion 61 and the boundary portion 62. It is desirable that the width E be larger than the gap C.
[0033] It is also desirable that the stepped portion 10 has an inclined shape that widens toward the inside. In Figure 13, this is achieved by the boundary portion 62 being an inclined surface facing toward the storage space. In this way, the container 1 of this embodiment has a configuration that makes it difficult for the contents to be pinched at the butt point between the fixed member 5 and the movable member 6. At the same time, it also prevents foreign objects from entering the storage space from the outside.
[0034] The shape of the stepped portion 10 is not limited to that shown in FIG. 13 . Modified examples are shown in FIGS. 14 to 17 . In FIG. 14 , almost the entire inner surface of the movable member 6 is formed as a concave portion 61. The normal portion 60 and the concave portion 61 can be considered to be substantially flush with each other. In FIG. 15 , the boundary portion 62 is formed as a vertical surface rather than an inclined surface. In FIG. 16 , not only the boundary portion 62 but also the tip surface 53 of the fixed member 5 are inclined surfaces facing the storage space. In FIG. 17 , the boundary portion 62 is formed as a vertical surface, and at least a portion of the tip surface 53 is inclined surfaces facing the storage space. These configurations also prevent pinching of stored items at the joint between the fixed member 5 and the movable member 6 while preventing foreign objects from entering the storage space from the outside. The stepped portion 10 of FIG. 16 and the stepped portion 10 of FIG. 17 also achieve a shape that widens toward the interior.
[0035] In the explanation so far, the first and second constituent members relating to the stepped portion 10 are both members that form the side wall portions of the long sides of the container 1. However, the features of the disclosed technology can also be applied to other parts of the container 1. As an example, an application example to the butting part between the bottom member 2 and the short side wall member 3 will be described with reference to Figures 18 and 19.
[0036] Figure 18 is an enlarged view of area M in Figure 1. It depicts the vicinity of the corners of three sides of the bottom member 2, the short-side wall member 3, and the long-side wall member 4. The focus here is on the lower part of the short-side wall member 3. There is a bank portion 20 there, and the bank portion 20 is part of the bottom member 2. As can be seen in Figure 18, two stepped portions 21 that are partially recessed are formed in the bank portion 20. Visible between the stepped portions 21 is a member known as a gap cover 22. The gap cover 22 is an independent member that is not part of either the bottom member 2 or the short-side wall member 3. The gap cover 22 is also one of the resin components of the container 1.
[0037] FIG. 19 shows the portion below the cut surface of the container 1 when it is cut along the horizontal plane at level AA in FIG. 18. Level AA is slightly below the level where the bottom member 2 and the short-side wall member 3 butt together. The hatched portion in FIG. 19 is the surface that appears when cut. Most of what appears in FIG. 19 is a portion of the bottom member 2. As shown in FIG. 19, a bag-shaped hinge receiving portion 23 is formed in the bank portion 20 of the bottom member 2. The hinge receiving portion 23 is a portion that opens toward the interior and upward of the container 1. However, the opening on the interior side of the hinge receiving portion 23 is closed by a gap cover 22. The opening above the hinge receiving portion 23 is closed by the short-side wall member 3. The gap cover 22 is attached to or around the hinge receiving portion 23 in the bank portion 20. The hinge portion 30 is located inside the hinge receiving portion 23. The hinge portion 30 is not a part of the bottom member 2 but a part of the short side wall member 3. With the gap cover 22 attached, the short side wall member 3 can be tilted inward around the hinge portion 30 to achieve the state shown in FIG.
[0038] The gap cover 22 may also be configured to be attached to the hinge portion 30 instead of to the bank portion 20. In this configuration, with the gap cover 22 attached, the short-side wall member 3 can be tilted inward around the hinge portion 30 to achieve the state shown in Fig. 3. The gap cover 22 may also be configured to close the opening on the inner side of the hinge receiving portion 23 and at least a part of the upper opening.
[0039] As shown in FIG. 19 , a concave portion 24 is provided as a part of the bank portion 20. The concave portion 24 is provided on the interior side of the container 1 at the hinge receiving portion 23 so as to partially limit the opening range. The concave portion 24 also forms a step with respect to the portion of the inner wall surface of the bank portion 20 other than the concave portion 24. The gap cover 22 is provided with a first protrusion 25. As shown in FIG. 19 , in the container 1, a portion of the first protrusion 25 and a portion of the concave portion 24 overlap in the inward / outward direction. In this overlapping section, the concave portion 24 is located outside the first protrusion 25 in the inward / outward direction of the container 1, and the inner surface of the concave portion 24 and the outer surface of the first protrusion 25 are in contact with each other. As a result, a step-shaped portion 21 is formed where the bank portion 20 and the gap cover 22 butt against each other. The step-shaped portion 21 also contributes to preventing contents from being pinched between the bank portion 20 and the gap cover 22. Similarly, a step-shaped portion can be provided between the bank portion 26 on the long side of the bottom surface member 2 and the gap cover 27 (see FIG. 18).
[0040] As described above in detail, according to this embodiment, an overlapping section is provided at the butt joint of the multiple resin components that make up the container 1, so that the two components overlap inward and outward directions. A stepped portion is formed adjacent to the overlapping section. This makes it possible to realize a container 1 that is less likely to have contents trapped between the components.
[0041] It should be noted that this embodiment is merely an example and does not limit the disclosed technology in any way. Therefore, the disclosed technology can naturally be improved and modified in various ways without departing from the spirit and scope of the invention. For example, in the above embodiment, the stepped portions 10 and 21, which are steps with respect to the inner wall surface 50, are both recessed relative to other portions as viewed from the storage space of the container 1. However, the present invention is not limited to this, and may be a stepped portion configured to be convex relative to other portions as viewed from the storage space.
[0042] The step-shaped portion can be applied not only to the butt portion between the fixed member 5 and the movable member 6, or the butt portion between the bottom member 2 and the gap cover 22, but also to any butt portion between components, such as the butt portion between the short-side wall member 3 and the long-side wall member 4. If a cover member is provided in addition to the components shown in Fig. 1, the step-shaped portion can also be applied to the butt portion between the cover member and other components. The bank portion 20 shown in Fig. 18 may have no step-shaped portion 21 (see Figs. 5 and 8).
[0043] The container 1 according to this embodiment is embodied such that both the short side wall member 3 and the long side wall member 4 are foldable (see FIGS. 3 and 4). However, this is not limiting, and it is also possible to embody an assembled container in which at least one of the short side wall member 3 and the long side wall member 4 is detachable from the bottom member 2. Alternatively, it is also possible to embody a container in which at least one of the short side wall member 3 and the long side wall member 4 is a separate member from the bottom member 2 but is not detachable once attached.
