Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in order to prevent the lid body from being displaced in the closing direction when an article is inserted into or removed from the container, it may be considered to hold the lid body with one hand. However, in that case, since the article is inserted into or removed with one hand, there is a concern that the workability is not good.

[0005] The present invention has been made to solve the above-exemplified problems and the like, and an object thereof is to provide a container capable of improving workability when an article is inserted into or removed.

Means for Solving the Problems

[0006] Hereinafter, each means suitable for solving the above object and the like will be described separately. In addition, effects and the like specific to the corresponding means will be appended as necessary.

[0007] Means 1. A container body having a substantially box shape that opens upward and having a storage portion capable of storing an article inside, A lid capable of closing the opening of the container body, The container body is connected to the lid in a rotatable and displaceable manner by a connecting portion, The lid is configured to be displaceable between an open position, which opens the opening of the container body and allows articles to be inserted into and removed from the storage compartment, and a closed position, which closes the opening. The system includes a restricting means capable of restricting the displacement of the lid from a predetermined open position toward the closed position. 、 The aforementioned regulatory means are A restricting projection is provided on the container body, which extends from a position on the outer circumference of the opening, beyond the edge of the opening, and above the edge of the opening. The lid is provided with a clamping portion that, when the lid is in a predetermined open position, is positioned on both the inner and outer sides of the container body in the inward-outward direction and clamps the restricting projection, The portion of the restricting projection that can be clamped by the clamping portion, and the clamping portion are provided at a position different from the connecting portion, When the lid is in the predetermined open position and the restricting projection is held in place by the clamping portion, the lid is restricted from further displacement toward the open position and also restricted from further displacement toward the closed position. A container characterized by the following features.

[0008] According to method 1, the lid can be held in the open position by the regulating means. Therefore, the worker does not need to hold the lid with one hand to prevent it from shifting towards the closed position, and can use both hands to load and unload items more efficiently and safely without being distracted by holding the lid. In particular, when loading and unloading a large number of items into and out of the container (when the loading and unloading cannot be completed in a single operation with one hand, or when it is necessary to leave the container in the middle of loading or unloading items), time efficiency can be further improved. In addition, when loading and unloading items that are preferable to hold with both hands, or when loading items while organizing already contained items, items can be loaded and unloaded more safely and smoothly. Thus, it is possible to improve the workability when loading and unloading items. Furthermore, the regulating projection can be held in place when clamped by the clamping portion, thereby enabling the lid to be held in a predetermined open position. Moreover, since the portion of the regulating projection that can be clamped by the clamping portion, and the clamping portion itself, are provided at a different location from the connecting portion (separate from the connecting portion), damage to the connecting portion when the displacement of the lid in the open position is restricted can be suppressed, thereby improving the durability of the connecting portion.

[0009] Means 2. The lid comprises a first component and a second component provided so as to form an internal space between the first component and the second component. The clamping portion comprises an inner clamping portion located on the inside of the container body in the inward-outward direction relative to the restricting projection when the lid is in the predetermined open position, and an outer clamping portion located on the outside. The container according to means 1, characterized in that the inner clamping portion is composed of the first component and the second component, and at least a portion of the lid is a double-wall structure of the first component and the second component when the lid is in the predetermined open position.

[0010] According to method 2, By reinforcing the inner clamping portion that restricts the displacement of the lid from a predetermined open position toward the closed position, deformation and damage can be prevented. This effect is particularly pronounced when a force is applied toward the closed position to the lid when it is in a predetermined open position (for example, when a part of the lid protrudes above the opening of the container body, or when an item is stored in a pocket provided on the underside of the lid). Furthermore, damage to the inner clamping portion can be suppressed when a force is applied to displace the lid toward the closed position without releasing the restriction imposed by the regulating means for the lid when it is in a predetermined open position.

[0011] Means 3. A container body having a roughly box-like shape with an opening at the top and a storage compartment inside capable of accommodating articles, A lid capable of closing the opening of the container body, The container body is connected to the lid in a rotatable and displaceable manner by a connecting portion, The lid is configured to be displaceable between an open position, which opens the opening of the container body and allows articles to be inserted into and removed from the storage compartment, and a closed position, which closes the opening. The system includes a restricting means capable of restricting the displacement of the lid from a predetermined open position toward the closed position, The lid is configured to be displaceable in the vertical direction at a predetermined open position. The connecting portion comprises a shaft portion provided on one side of the lid and the container body and protruding along the rotation axis direction of the lid, and a bearing portion provided on the other side of the lid and the container body into which the shaft portion is inserted. The bearing portion comprises a rotating portion that allows relative rotational displacement of the shaft portion, and a sliding portion that is provided continuously above and below the rotating portion and allows relative sliding displacement of the shaft portion in the vertical direction when the cover is in a predetermined open position. The aforementioned regulatory means are A restricting projection is provided on the container body, which extends from a position on the outer circumference of the opening, beyond the edge of the opening, and above the edge of the opening. The lid is provided with a clamping portion that, when the lid is in a predetermined open position, is positioned on both the inner and outer sides of the container body in the inward-outward direction and clamps the restricting projection, The portion of the restricting projection that can be clamped by the clamping portion, and the clamping portion are provided at a position different from the connecting portion, The container body is provided with a connecting projection that extends from a position on the outer circumference of the opening, beyond the edge of the opening, and above the edge of the opening, The bearing portion is provided in the connecting projection. A container characterized in that the portion of the restricting projection that can be clamped by the clamping portion and the connecting projection are connected to each other and integrated in such a way that they form different block-shaped surfaces.

[0012] According to method 3, the portion of the restricting projection that can be clamped by the clamping portion and the connecting projection can be arranged as compactly as possible while increasing the strength and rigidity of each. Furthermore, since the restricting projection (connecting projection) is located on the outer circumference of the opening (behind the rear edge of the opening) of the container body, contact between the restricting projection (connecting projection) and the article can be suppressed when the article is being inserted or removed, thereby preventing damage to the restricting projection (connecting projection) and the article.

[0013] Means 4. A container body having a roughly box-like shape with an opening at the top and a storage compartment inside capable of accommodating articles, A lid capable of closing the opening of the container body, The container body is connected to the lid in a rotatable and displaceable manner by a connecting portion, The lid is configured to be displaceable between an open position, which opens the opening of the container body and allows articles to be inserted into and removed from the storage compartment, and a closed position, which closes the opening. The system includes a restricting means capable of restricting the displacement of the lid from a predetermined open position toward the closed position, The container body comprises a bottom wall component, a side wall component projecting upward from the side edge of the bottom wall component, and a protruding wall component projecting outward from the upper edge of the side wall component. The cover comprises a first overlapping portion that overlaps the protruding wall portion when the cover is in the closed position, and a second overlapping portion that overlaps the protruding wall portion when the cover is in the predetermined open position. A container characterized in that the first overlapping portion and the second overlapping portion are connected to each other.

[0014] According to method 4, when the lid is in the closed position, the first overlapping portion and the protruding wall portion overlap vertically, thereby improving the airtightness of the container. Furthermore, when the lid is in the predetermined open position, the second overlapping portion and the protruding wall portion overlap vertically, thereby reducing or eliminating the load of the lid acting on the connecting portion, and preventing deterioration, damage, etc., of the connecting portion. In addition, since the first overlapping portion and the second overlapping portion are connected to each other, their strength and rigidity can be increased.

[0015] Means 5. A container body having a roughly box-like shape with an opening at the top and a storage compartment inside capable of accommodating articles, A lid capable of closing the opening of the container body, The container body is connected to the lid in a rotatable and displaceable manner by a connecting portion, The lid is configured to be displaceable between an open position, which opens the opening of the container body and allows articles to be inserted into and removed from the storage compartment, and a closed position, which closes the opening. The system includes a restricting means capable of restricting the displacement of the lid from a predetermined open position toward the closed position, The connecting portion is provided on the lid and includes a shaft portion that protrudes along the rotation axis direction of the lid, The container body is provided with a restricting projection that extends from a position on the outer periphery of the opening, beyond the edge of the opening, and above the edge of the opening. The aforementioned restricting projection extends in the left-right direction of the container body, The bearing portion into which the shaft portion is inserted is provided at the left and right ends of the restricting projection, The container is characterized in that the lid has a covering wall portion that abuts against the outer surface of the restricting projection at a predetermined open position and is capable of restricting the displacement of the lid further toward the open position.

[0016] According to means 5, the lid can be held in the open position by the restricting means. Therefore, the worker does not need to hold the lid with one hand to prevent it from displacing towards the closed position, and can use both hands to load and unload items more efficiently and safely without being distracted by holding the lid. In particular, when there are many items to load and unload from the container (when the loading and unloading cannot be completed in one go with one hand, or when it is necessary to leave the container in the middle of loading or unloading items), time efficiency can be further improved. Also, when loading or unloading items that are preferable to hold with both hands, or when loading items while organizing already stored items, items can be loaded and unloaded more safely and smoothly. Thus, the workability when loading and unloading items can be improved. Furthermore, at the predetermined open position, the covering wall portion of the lid abuts against the outer surface of the restricting projection, restricting the lid from displacing any further towards the open position.

[0017] Means 6. The connecting portion is provided corresponding to the rear edge of the container in the front-rear direction of the edge of the opening, The container according to any one of the means 1 to 5, characterized in that the container is installed on an installation surface extending substantially horizontally, and the rear part of the container body is in substantially contact with a predetermined wall portion extending substantially vertically, while the lid in the closed position is configured to be rotatably displaceable until the upper surface of the lid in the closed position is in a predetermined open position that extends substantially perpendicularly to the installation surface, and the lid in the predetermined open position is configured to be held by the regulating means.

[0018] According to method 6, even if the rear of the container body is positioned to be roughly in contact with a predetermined wall when the container is installed on the installation surface, the lid can be opened and closed without any problems. For example, if the rear end (top surface) of the lid in the open position protrudes further back than the rear end of the container body, and the container is installed on the installation surface with the rear of the container body roughly in contact with a predetermined wall, it becomes difficult to properly open the lid, or opening the lid causes it to be pressed against the predetermined wall (in some cases, the container body may tilt and the contents may fall over). This avoids such problems. Therefore, the container can be positioned with the container body roughly in contact with a predetermined wall without any problems in opening and closing the lid, making the space efficiency of the container installation location as good as possible, while avoiding damage to the predetermined wall or lid each time the lid is opened.

[0019] Furthermore, the term "abbreviated" does not strictly specify a particular state, but rather includes states that approximate within a range of commonly accepted error and precision, and to the extent that the intended function and effect can be achieved. In addition, a lid that is set to a predetermined open position and held by a regulating means is restricted from displacing towards the closed position, and also restricted from displacing further towards the open position.

[0020] Furthermore, the lid is configured to be displaceable in the vertical direction at the predetermined open position. The connecting portion comprises a shaft portion provided on one side of the lid and the container body and protruding along the rotation axis direction of the lid, and a bearing portion provided on the other side of the lid and the container body into which the shaft portion is inserted. The bearing portion comprises a rotating portion that allows relative rotational displacement of the shaft portion, and a sliding portion that is provided continuously above and below the rotating portion and allows relative sliding displacement of the shaft portion in the vertical direction when the cover is in the predetermined open position. The shaft portion located on the sliding portion may be configured to have its rotational displacement restricted by the sliding portion.

[0021] According to the above configuration, by positioning the shaft on the sliding part, the rotational displacement of the shaft is restricted, and consequently, the rotational displacement of the lid from a predetermined open position toward the closed position (and further displacement toward the open position) is restricted. In other words, the connecting part that connects the lid to the container body so that it can rotate and displace also has the function of holding the lid in the open position and thus serves as a restricting means, allowing the structure of the connecting part and the restricting means to be made as compact as possible. Furthermore, the simplification of the structure also contributes to the weight reduction of the container. Moreover, by rotating the lid to a predetermined open position and then displacing the lid vertically, the displacement of the lid toward the closed position can be restricted. For example, compared to a configuration in which a separate locking member is provided to restrict the displacement of the lid toward the closed position from a predetermined open position, and the locking member is operated to lock the lid when the lid is in the predetermined open position, the lid can be held in the open position or released from that holding state simply by displacing the lid, thereby improving workability and other aspects.

[0023] An embodiment will be described below with reference to the drawings. As shown in Figures 1 and 2, the container 1 is a roughly rectangular box shape opening upwards and comprises a container body 2 having a storage section 3 inside that can accommodate articles, a lid 5 that can close the opening 4 of the container body 2, and a connecting part 6 that rotatably connects the lid 5 to the container body 2. As will be described in more detail later, the connecting part 6 is provided corresponding to the rear edge of the opening 4 of the container body 2 in the front-rear direction of the container 1. The lid 5 is configured to be displaceable between an open position that opens the opening 4 of the container body 2 and allows articles to be inserted into and removed from the storage section 3, and a closed position that closes the opening 4. Note that "roughly" does not strictly specify a predetermined state, but rather includes states that approximate within a range of commonly accepted error and precision, and within a range that can achieve the intended function and effect.

[0024] As shown in Figures 5 and 6, the container body 2 comprises a bottom wall component 11 that is roughly rectangular in plan view, and a front side wall component 12, a rear side wall component 13, a left side wall component 14, and a right side wall component 15 that project upward from the front edge, rear edge, and left and right side edges of the bottom wall component 11, respectively. In this embodiment, the top surface of the container body 2 is inclined downward toward the front. That is, the height of the front side wall component 12 is lower than the height of the rear side wall component 13, and the upper edges of the left side wall component 14 and the right side wall component 15 are continuous with the upper edge of the front side wall component 12 and include a portion that extends roughly parallel to the upper edge of the front side wall component 12, a portion that is continuous with the upper edge of the rear side wall component 13 and extends roughly parallel to the upper edge of the rear side wall component 13, and a portion that connects them while inclined.

[0025] Furthermore, as shown in Figure 8, the container body 2 of this embodiment comprises a first body-side component 16 that mainly constitutes the outer surface of the container body 2, and a second body-side component 17 that is provided between the first body-side component 16 and the second body-side component 17, which forms an internal body-side space 18 (see Figures 15 to 17) and mainly constitutes the inner surface of the container body 2.

[0026] The second component 17 on the main body side comprises a substantially rectangular plate-shaped inner bottom wall portion 20 that constitutes the inner surface (inner bottom surface) of the bottom wall component 11, inner side wall portions 21 that extend upward from each side edge of the inner bottom wall portion 20 and constitute the inner surface of the front side wall portion 12, rear side wall portion 13, left side wall portion 14, and right side wall portion 15, an upper side wall portion 22 that protrudes outward from the upper edge of each inner side wall portion 21 to the outside of the container body 2, and a folded portion 23 that protrudes downward from the leading edge (outer edge) of the upper side wall portion 22. At the connection point between the upper side wall portion 22 and the inner side wall portion 21, a mating recess 24 (see Figures 5, 17, etc.) is provided, formed by recessing the upper side wall portion 22 and the inner side wall portion 21 downward.

[0027] The main body side first component 16 includes an outer bottom wall portion 26 that is substantially rectangular in plan view and forms the outer surface (bottom surface, contact surface) of the bottom wall component 11, outer side wall portions 27 that extend upward from each side edge of the outer bottom wall portion 26 and form the outer surfaces of the front side wall portion 12, rear side wall portion 13, left side wall portion 14, and right side wall portion 15, a protruding wall portion 28 (see Figure 17, etc.) that protrudes outward from the upper edge of each outer side wall portion 27 toward the outside of the container body 2, and a locking projection portion 29 that is provided so as to extend the upper edge of the outer side wall portion 27 upward and protrudes above the protruding wall portion 28. The protruding wall portion 28 is provided continuously around the entire circumference along the upper edge of each outer side wall portion 27.

[0028] By inserting the second component 17 of the main body into the first component 16 of the main body, as shown in Figures 15 to 17, the locking projection 29 of the first component 16 of the main body is inserted relative to and abuts against the lower surface of the upper wall portion 22 of the second component 17 of the main body, and the folded portion 23 of the second component 17 of the main body is in close proximity to the outer surface of the locking projection 29 (approximately locked state). Furthermore, the internal space 18 of the main body is formed between the inner bottom wall portion 20 and the outer bottom wall portion 26, and between the inner side wall portion 21 and the outer side wall portion 27, and a heat insulating material 8 (for example, expanded polystyrene) molded into a predetermined shape is provided in the internal space 18 of the main body. The first component 16 of the main body and the second component 17 of the main body are each integrally formed from polypropylene. Furthermore, a locking mechanism (not shown) may be provided to restrict the relative vertical displacement between the first component 16 on the main body side and the second component 17 on the main body side.

[0029] As shown in Figure 3, when the container body 2 is installed on an installation surface 81 that extends substantially horizontally, the inner bottom wall portion 20 and the outer bottom wall portion 26 extend substantially horizontally, while the inner side wall portion 21 and the outer side wall portion 27 extend substantially vertically (see Figures 15 and 16). Furthermore, as shown in Figures 17 and 18, the protruding wall portion 28 of the first component portion 16 on the main body side protrudes further outward from the container body 2 than the folded portion 23 of the second component portion 17 on the main body side. Since the outer surface of the outer side wall portion 27 constitutes the outer surface of the container body 2, it can be said that the protruding wall portion 28 protrudes outward from the front side wall portion 12, the rear side wall portion 13, the left side wall portion 14, and the right side wall portion 15.

[0030] As shown in Figures 5 and 6, the lid 5, when in the closed position, has a roughly rectangular shape in plan view and comprises a top wall portion 31 that covers the top of the container body 2, and a front lid wall portion 32, a left lid wall portion 33, and a right lid wall portion 34 that protrude downward from the front edge and left and right side edges of the top wall portion 31, respectively. As described above, the upper surface of the container body 2 (the frame-shaped portion formed by the upper edges of the front side wall portion 12, the rear side wall portion 13, the left side wall portion 14, and the right side wall portion 15) is inclined downward toward the front. In contrast, as shown in Figure 3, when the container 1 is placed on a horizontal mounting surface 81, the lid 5 is configured such that the upper surface of the top wall portion 31 of the lid 5 in the closed position extends substantially horizontally. This is achieved by supporting the top wall portion 31 in a position that extends substantially horizontally with the front lid wall portion 32, the left lid wall portion 33, and the right lid wall portion 34, and closing the gap between the top wall portion 31 and the container body 2. The lower edges of the front lid wall portion 32, the left lid wall portion 33, and the right lid wall portion 34 are supported by the upper edges of the front side wall portion 12, the left side wall portion 14, and the right side wall portion 15 of the container body 2 when the lid 5 is in the closed position. With this configuration, when the container 1 is in the closed position, a storage portion 3 is also formed on the lid 5 side at an upper position on the front side of the container body 2 (opening 4) (see Figure 17), and the storage space of the container 1 in the closed position is expanded. Furthermore, when describing lid 5, unless otherwise specified, the description will generally assume that lid 5 is in the closed position.

[0031] Furthermore, as shown in Figure 7, the lid 5 comprises a lid-side first component 35 that mainly constitutes the outer surface of the lid 5, and a lid-side second component 36 that is provided so as to form a lid-side internal space 37 (see Figures 11 and 17) between the lid-side first component 35 and the lid-side second component 36 that mainly constitutes the inner surface of the lid 5.

[0032] The lid-side second component 36 comprises a substantially rectangular plate-shaped inner top wall portion 39 that constitutes the inner surface of the top wall portion 31, inner lid wall portions 40 that extend downward from the front edge and left and right side edges of the inner top wall portion 39 and constitute the inner surfaces of the front lid wall portion 32, left lid wall portion 33, and right lid wall portion 34, and a joint wall portion 41 that protrudes outward from the lower edge of each inner lid wall portion 40 and the rear edge of the inner top wall portion 39 to the outside of the container body 2. The joint wall portion 41 is provided continuously around the entire circumference along the lower edge of each inner lid wall portion 40 and the rear edge of the inner top wall portion 39. Furthermore, in the joint wall portion 41, joint protrusions 42 (see Figures 15, 17, etc.) are provided at the connection portion with the inner lid wall portion 40 and the connection portion with the rear edge of the inner top wall portion 39, so as to cause the joint wall portion 41 to bulge downward.

[0033] The lid-side first component 35 comprises a substantially rectangular plate-shaped outer top wall portion 44 that constitutes the outer surface side of the top wall portion 31 (the upper surface when the lid 5 is in the closed position), outer lid wall portions 45 that extend downward from the front edge and left and right side edges of the outer top wall portion 44 and constitute the outer surfaces of the front lid wall portion 32, left lid wall portion 33, and right lid wall portion 34, and a first overlapping portion 46 (see Figure 5, etc.) that protrudes outward from the lower edge of each outer lid wall portion 45 toward the outside of the container body 2. Furthermore, the lid-side first component 35 includes a shaft front wall portion 47 extending downward from the rear edge of the outer top wall portion 44, a shaft covering wall portion 48 provided so as to extend the outer top wall portion 44 toward the rear side of the container 1 and projecting rearward from the shaft front wall portion 47, and shaft outer wall portions 49 provided so as to extend the left and right outer lid wall portions 45 toward the rear side of the container 1 and projecting rearward from the shaft front wall portion 47. In addition, the lid-side first component 35 includes a pair of left and right shaft base wall portions 50, each positioned opposite each shaft outer wall portion 49 at a predetermined distance toward the central part of the container 1 in the lateral direction, and connected to the shaft front wall portion 47 and the shaft covering wall portion 48, respectively, and a shaft portion 51 projecting from each shaft base wall portion 50 toward the central part of the container 1 in the lateral direction. The lower edge of the shaft front wall portion 47 is located above the lower edge of the shaft outer wall portion 49. Furthermore, the rear lower corner and the rear upper corner (boundary with the shaft covering wall 48) of the shaft outer wall portion 49 are each rounded in shape.

[0034] By inserting the second lid component 36 inside the first lid component 35, the locking means 52 (see Figure 7) provided between the inner top wall 39 and the outer top wall 44 restricts the relative vertical displacement between the first lid component 35 and the second lid component 36. Furthermore, as shown in Figures 15 and 17, the outer edge of the mating wall portion 41 of the lid-side second component 36 is close to (or in contact with) the inner surface of the outer lid wall portion 45 of the lid-side first component 35. Also, as shown in Figure 16, with respect to the rear edge of the mating wall portion 41 (the lower edge in Figure 16, which shows the lid 5 in the open position), when the lid 5 is in the closed position, its upper surface (the right surface in Figure 16) is in contact with the lower edge of the shaft front wall portion 47 (the left edge in Figure 16), and furthermore, the rear edge (the lower edge in Figure 16) extends further to the rear side of the container body 2 (downward in Figure 16) than the shaft front wall portion 47. Furthermore, as shown in Figure 17, etc., the lid-side internal space 37 is formed between the inner top wall portion 39 and the outer top wall portion 44, and between the inner lid wall portion 40 and the outer lid wall portion 45, and a heat insulating material 8 (for example, expanded polystyrene) molded into a predetermined shape is provided in the lid-side internal space 37. The lid-side first component portion 35 and the lid-side second component portion 36 are each integrally formed from polypropylene.

[0035] Now, as shown in Figures 2 and 4, the container 1 of this embodiment is configured such that when the container 1 is installed on an installation surface 81 that extends substantially horizontally, the lid 5 rotates approximately 90 degrees from the closed position to the open position, and the top wall portion 31 is positioned in a substantially vertical direction (substantially perpendicular to the installation surface) (hereinafter referred to as the "upright open position"), the displacement of the lid 5 toward the closed position can be restricted. In this embodiment, the upright open position corresponds to a "predetermined open position".

[0036] As shown in Figures 5, 8, and 16, the container body 2 is provided with a restricting projection 61 that protrudes upward from a protruding wall portion 28 that protrudes rearward from the upper edge of the rear side wall portion 13 (outer side wall portion 27 which constitutes the outer surface). The restricting projection 61 comprises an inner restricting wall portion 62 that extends upward from the protruding wall portion 28 at a distance from the locking projection 29 that allows for the insertion of the folded portion 23 of the second component portion 17 on the main body side; an upper wall portion 63 that extends outward from the upper edge of the inner restricting wall portion 62 to the outer side of the container body 2; and an outer restricting wall portion 64 that extends downward from the outer edge of the upper wall portion 63. In this embodiment, the restricting projection 61 extends in the left-right direction of the container body 2, from the left outer side wall portion 27 to the right outer side wall portion 27 (it does not exist to the sides of the outer side wall portion 27). Furthermore, as shown in Figures 5, 8, and 10, the restricting projection 61 is connected at both ends in the left-right direction of the container body 2 so as to close the space between the inner restricting wall 62, the upper wall 63, and the outer restricting wall 64, and is also provided with a connecting projection 65 that is connected to the protruding wall 28.

[0037] As shown in Figure 10, the connecting projection 65 is provided by forming a hole through the connecting projection 65 and includes a bearing portion 66 into which the shaft portion 51 of the lid 5 is inserted. The bearing portion 66 includes a rotating portion 67 which is substantially circular in front view and allows relative rotational displacement of the shaft portion 51, and a sliding portion 68 which is provided below the rotating portion 67 and is continuous (communicating) with the rotating portion 67, and allows relative sliding displacement of the shaft portion 51 in the vertical direction when the lid 5 is in the upright open position. In this embodiment, the connecting portion 6 is composed of the shaft portion 51 and the bearing portion 66.

[0038] More specifically, as shown in Figure 9, the shaft portion 51 has a substantially oval shape in a cross-section perpendicular to its protruding direction, comprising a pair of opposing arc-shaped portions and a pair of opposing straight portions. The width between the arc-shaped portions is the longitudinal width of the shaft portion 51 (in terms of its cross-sectional shape), and the width between the straight portions is the short width of the shaft portion 51 (in terms of its cross-sectional shape). Furthermore, when the lid 5 is in the upright open position, the longitudinal width of the shaft portion 51 is configured to extend in the height direction (up and down direction) of the container 1. In contrast, as shown in Figure 11, the inner diameter of the rotating portion 67 is configured to be slightly larger than the longitudinal width of the shaft portion 51, and as shown in Figure 14, the width of the sliding portion 68 (in the front-rear direction of the container 1) is configured to be slightly larger than the short width of the shaft portion 51 and smaller than the longitudinal width of the shaft portion 51.

[0039] Then, by rotating the lid 5, which is in the closed position as shown in Figure 11, to the upright open position as shown in Figures 12 and 13, the shaft portion 51, which was rotated in the rotating portion 67, is displaced downward and can be inserted into the sliding portion 68 as shown in Figure 14. In other words, the lid 5 is configured to be displaceable in the upright open position. Furthermore, the shaft portion 51 located in the sliding portion 68 is restricted from rotational displacement by the sliding portion 68 (the front and rear edges of the sliding portion 68), and consequently, the displacement of the lid 5 in the upright open position further toward the open position and further toward the closed position is restricted.

[0040] As shown in Figures 6, 7, and 11, the lid 5, when in the closed position, has an inner support portion 69 that protrudes outward from the container body 2 from the lower edge of the shaft front wall portion 47, including the central part in the lateral width direction of the container 1. As shown in Figures 14 and 16, when the lid 5 is in the upright open position and the shaft portion 51 is positioned on the sliding portion 68, the regulating projection 61 is relatively inserted between the inner support portion 69 of the lid 5 and the shaft covering wall portion 48, so that the inner support portion 69 and the inner regulating wall portion 62 are in contact with or close to each other in the inward and outward directions of the container body 2, and the shaft covering wall portion 48 and the outer regulating wall portion 64 are in contact with or close to each other. In other words, the inner support portion 69 and the shaft covering wall portion 48 of the lid 5 are positioned on both the inner and outer sides of the container body 2 in the inward and outward direction, and are configured to sandwich the restricting projection 61 (inner restricting wall portion 62 and outer restricting wall portion 64). As a result, the lid 5, which is in the upright open position, is restricted from being displaced further towards the open position and towards the closed position.

[0041] As shown in Figure 13, in this embodiment, by rotating the lid 5 from the closed position by approximately 90 degrees toward the open position, even when the shaft portion 51 is located on the rotating portion 67, the shaft covering wall portion 48 abuts against the outer surface of the outer restricting wall portion 64, thereby restricting further displacement of the lid 5 toward the open position. In addition, as shown in Figure 11, when the lid 5 is in the closed position, the rear edge of the inner support portion 69 is located further inward of the container body 2 than the rear edge of the shaft covering wall portion 48, so as not to hinder the rotational displacement of the lid 5. Furthermore, as described above, with respect to the rear edge of the mating wall portion 41 of the lid-side second component 36, as shown in Figures 11 and 16, when the lid 5 is in the closed position, its upper surface (the right surface in Figure 16 when the lid 5 is in the upright open position) abuts against the lower edge of the shaft front wall portion 47, and furthermore, the rear edge extends further to the rear of the container body 2 than the shaft front wall portion 47, and within the formation range of the inner support portion 69, the mating wall portion 41 and the inner support portion 69 are configured to abut each other surface vertically (front and rear when the lid 5 is in the upright open position). Note that the rear edge of the mating wall portion 41 is located further inward of the container body 2 than the rear edge of the inner support portion 69.

[0042] In this embodiment, the portion of the mating wall portion 41 (of the lid-side second component 36) that overlaps with the inner support portion 69, and the inner support portion 69 (of the lid-side first component 35) constitute an inner clamping portion, and the shaft covering wall portion 48 constitutes an outer clamping portion, and these inner and outer clamping portions constitute a clamping portion. Furthermore, the portion of the restricting projection 61 that is composed of the inner restricting wall portion 62 and the outer restricting wall portion 64 constitutes the "portion of the restricting projection that can be clamped by the clamping portion." Moreover, in this embodiment, the restricting means is composed of a connecting portion restricting mechanism that restricts the rotational displacement of the shaft portion 51 located on the slide portion 68 of the bearing portion 66, and a non-connecting portion restricting mechanism in which the restricting projection 61 (inner restricting wall portion 62 and outer restricting wall portion 64) is clamped by the inner support portion 69 (matting wall portion 41) and the shaft covering wall portion 48. In addition, in this embodiment, when restricting the displacement of the lid 5 in the upright open position toward the open position and toward the closed position, both the connecting part restricting mechanism and the non-connecting part restricting mechanism function and cooperate to restrict the said displacement.

[0043] Furthermore, as shown in Figure 16, the protruding wall portion 28 that projects rearward from the upper edge of the rear side wall portion 13 (outer side wall portion 27) is configured to also exist behind the restricting projection 61, and the rear edge of the protruding wall portion 28 constitutes part of the rear end of the container body 2 (see Figure 6). As shown in Figures 4, 14, and 16, the upper surface of the lid 5 (outer top wall portion 44 and shaft covering wall portion 48) is configured so that it does not protrude rearward from the rear edge of the protruding wall portion 28 when the container 1 is installed on an installation surface 81 that extends substantially horizontally and the lid 5 is held in the upright open position (the shaft portion 51 is located on the sliding portion 68) (for example, the upper surface of the lid 5 and the rear edge of the protruding wall portion 28 are located on a virtual plane that extends vertically). In addition, as shown in Figures 3 and 11, the rear end of the lid 5 in the closed position (the rear end edge of the shaft outer wall portion 49) is configured so that it does not protrude rearward from the rear edge of the protruding wall portion 28. Therefore, as shown in Figure 4, the container 1 is installed on an installation surface 81 extending in a substantially horizontal direction (for example, the floor surface in front of the entrance), and the rear of the container body 2 is kept in substantially contact with a predetermined wall portion 82 extending in a substantially vertical direction (for example, the exterior wall of a building), while the lid 5, which is in the closed position, can be rotated and displaced until it is in the upright open position.

[0044] Furthermore, as shown in Figures 15 and 17, when the lid 5 is in the closed position, the mating projection 42 of the lid 5 is inserted into the mating recess 24 provided along the opening 4 of the container body 2, and the first overlapping portion 46 of the lid 5 overlaps (is supported by contact with) the protruding wall portions 28 corresponding to the front wall portion 12, left wall portion 14, and right wall portion 15 of the container body 2. In addition, as shown in Figure 18, the lid 5 has a second overlapping portion 71 that protrudes outward (to the left and right sides of the container 1) from the lower edge of the axial outer wall portion 49 when the lid 5 is in the upright open position. The second overlapping portion 71 is curved along the lower edge. The connecting portion between the first overlapping portion 46 and the second overlapping portion 71 is also continuously curved. Furthermore, when the lid 5 is held in the upright open position (with the shaft portion 51 positioned on the sliding portion 68), the second overlapping portion 71 overlaps (is supported by contact with) the protruding wall portion 28 corresponding to the boundary between the left side wall portion 14, the right side wall portion 15, and the rear side wall portion 13. In addition, a protruding portion is provided on the lower edge of the shaft outer wall portion 49 when the lid 5 is in the closed position, which is continuous with the first overlapping portion 46 and the second overlapping portion 71 (the first overlapping portion 46 is extended rearward and connected to the second overlapping portion 71), thereby connecting the first overlapping portion 46 and the second overlapping portion 71 to each other. In addition, as shown in Figure 17, an outer overlapping portion 72 is provided that protrudes downward (rearward in the case of the second overlapping portion 71) from the outer edge (protruding tip) of the first overlapping portion 46 and the second overlapping portion 71. The provision of the outer overlapping portion 72 enhances the airtightness of the container 1 when it is closed, together with the matching protrusion 42 and the matching recess 24, thereby improving its cooling and heat retention performance.

[0045] Furthermore, as shown in Figure 2, the underside of the lid 5 is provided with a pocket portion 73 that opens upward when the lid 5 is in the upright open position and can accommodate a predetermined item (for example, paper). The pocket portion 73 is formed separately from the lid-side second component 36 and then attached to the lid-side second component 36. In addition, as shown in Figure 9, the surface of the leading end of each shaft portion 51 is provided with an inclined portion 74 formed by cutting out the front lower part when the lid 5 is in the upright open position, making it easier to insert the pair of shaft portions 51 into the pair of bearing portions 66 for pivot support.

[0046] As detailed above, according to this embodiment, the lid 5 can be held in the open position (upright open position). Therefore, the worker does not need to hold the lid 5 with one hand to prevent it from displacing towards the closed position when it is in the open position, and can use both hands to load and unload items more efficiently and safely without being distracted by holding the lid 5. In particular, when there are many items to load and unload from the container 1 (when the loading and unloading cannot be completed in one go with one hand, or when it is necessary to leave the container 1 in the middle of loading or unloading items), time efficiency can be further improved. Also, when loading or unloading items that are preferable to hold with both hands, or when loading items while organizing items that have already been stored, items can be loaded and unloaded more safely and smoothly. Thus, the workability when loading and unloading items can be improved.

[0047] Furthermore, in this embodiment, the container 1 is installed on an installation surface 81 that extends substantially horizontally, and while maintaining a state in which the rear of the container body 2 (the rear end of the protruding wall portion 28) is substantially in contact with a predetermined wall portion 82 that extends substantially vertically, the lid 5, which is in the closed position, is configured to be rotatable until the upper surface (outer top wall portion 44) of the lid 5, when in the closed position, is in an upright open position that extends substantially perpendicular to the installation surface 81, and the lid 5 is configured to be held in this upright open position. In other words, even if the rear of the container body 2 is substantially in contact with the predetermined wall portion 82 when the container 1 is installed on the installation surface 81, the lid 5 can be opened and closed without any problems. For example, if the container is placed on the installation surface with the rear of the container body substantially in contact with a predetermined wall, such that the rear end (top surface) of the lid in the open position protrudes further back than the rear end of the container body, it becomes difficult to properly open the lid, or opening the lid causes it to press against the predetermined wall (in some cases, the container body may tilt, causing the contents to fall over). This avoids such problems. Therefore, the container 1 can be positioned with the container body 2 substantially in contact with the predetermined wall 82 without hindering the opening and closing of the lid 5, maximizing space efficiency for the installation location of the container 1, while avoiding damage to the predetermined wall 82 or lid 5 each time the lid 5 is opened (for example, the lid 5 rubbing against the predetermined wall 82 and leaving a mark on the predetermined wall 82).

[0048] In addition, by rotating the lid 5, which is in the closed position, by approximately 90 degrees toward the open position, even when the shaft portion 51 is in the position of the rotating portion 67, the shaft covering wall portion 48 comes into contact with the outer surface of the outer restricting wall portion 64, thereby restricting further displacement of the lid 5 toward the open position. Therefore, when opening the lid 5, which is in the closed position, with the rear of the container body 2 substantially in contact with a predetermined wall portion 82, it is possible to avoid a situation where the lid 5 rotates beyond the upright open position, causing damage to the lid 5 or the predetermined wall portion 82.

[0049] Furthermore, the bearing portion 66 into which the shaft portion 51 is inserted and supported includes a rotating portion 67 that allows relative rotational displacement of the shaft portion 51, and a sliding portion 68 that is continuously provided below the rotating portion 67 and allows relative sliding displacement of the shaft portion 51 in the vertical direction when the lid 5 is in the upright open position. The shaft portion 51 located on the sliding portion 68 is configured so that its rotational displacement is restricted by the sliding portion 68. Therefore, by positioning the shaft portion 51 on the sliding portion 68, the rotational displacement of the shaft portion 51 is restricted, and consequently, the rotational displacement of the lid 5 in the upright open position toward the closed position, and further displacement toward the open position, are restricted. In other words, the connecting part 6 (shaft part 51 and bearing part 66) that connects the lid 5 to the container body 2 so that it can rotate and displace, also has the function of holding the lid 5 in the open position (it also serves as a restricting means). For example, compared to the case where a separate mechanism is provided to restrict the rotation of the lid 5 around the connecting part 6, the structure of the connecting part 6 and the restricting means can be made as compact as possible. Furthermore, the simplification of the structure also contributes to the weight reduction of the container 1. Moreover, by rotating the lid 5 to the upright open position and then displacing the lid 5 downward, the displacement of the lid 5 toward the closed position can be restricted. For example, compared to a configuration in which a separate locking member is provided to restrict the displacement of the lid 5 toward the closed position when the lid 5 is in the upright open position, and the locking member is operated to lock the lid 5 when it is in the upright open position, the lid 5 can be held in the open position or released from that position simply by displacing the lid 5, thereby improving workability and other aspects.

[0050] Furthermore, as a mechanism (restricting means) for holding the lid 5 in the upright open position, the lid 5 is placed in the upright open position, and then the shaft portion 51 is displaced to the sliding portion 68, so that the restricting protrusions 61 of the container body 2 (inner restricting wall portion 62 and outer restricting wall portion 64) are held between the inner support portion 69 and the shaft covering wall portion 48 of the lid 5 in the inward and outward directions of the container body 2. Moreover, this configuration (restricting mechanism other than the connecting portion) is provided at a different location (separate from the connecting portion 6) from the connecting portion 6 (connecting portion restricting mechanism). Therefore, the non-connecting portion restricting mechanism works in cooperation with the connecting portion restricting mechanism to more reliably prevent rotational displacement of the lid 5 in the upright open position, and reduces the burden on the connecting portion restricting mechanism, thereby suppressing damage to the connecting portion 6 and improving the durability of the connecting portion 6.

[0051] In addition, the inner support portion 69, formed by the first lid component 35, and the mating wall portion 41, formed by the second lid component 36, overlap in the inward and outward directions of the container body 2 when the lid 5 is in the upright open position, thus creating a double-wall structure. This allows for reinforcement of the inner support portion 69, preventing deformation or damage to the inner support portion 69 when the regulating mechanism (excluding the connecting portion) restricts the displacement of the lid 5 from the upright open position toward the closed position. This effect is particularly pronounced when a force is applied toward the closed position to the lid 5 in the upright open position (for example, when a part of the lid 5 protrudes above the opening 4 of the container body 2, or when an item is stored in the pocket portion 73 provided on the underside of the lid 5). Furthermore, damage to the inner support portion 69 can be suppressed when a force is applied to displace the lid 5 toward the closed position without releasing the restricted state of the lid 5 in the upright open position (while the shaft portion 51 remains in the sliding portion 68).

[0052] Furthermore, the connecting projection 65, on which the bearing portion 66 is provided, constitutes the left and right ends of the restricting projection 61. That is, the portion of the restricting projection 61 that can be held between the inner support portion 69 and the shaft covering wall portion 48 (inner restricting wall portion 62 and outer restricting wall portion 64) and the connecting projection 65 are connected to each other and integrated in such a way that they form surfaces with different block shapes. As a result, the portion of the restricting projection 61 that can be held between the inner support portion 69 and the shaft covering wall portion 48 and the connecting projection 65 can be arranged as compactly as possible while increasing the strength and rigidity of each. In addition, since the restricting projection 61 (connecting projection 65) is located on the outer circumference side of the opening 4 of the container body 2 (rearward from the rear edge of the opening 4), contact between the restricting projection 61 (connecting projection 65) and the article can be suppressed when articles are being inserted or removed, thereby preventing damage to the restricting projection 61 (connecting projection 65) and the article.

[0053] In addition, when the lid 5 is in the closed position, the first overlapping portion 46 of the lid 5 (lid-side first component 35) and the protruding wall portion 28 of the container body 2 (body-side first component 16) overlap vertically, thereby improving the airtightness of the container 1. Furthermore, when the lid 5 is in the closed position, it is possible to avoid situations where the load of the lid 5, or the load of an item placed on top of the lid 5 (or a downward force applied to the lid 5), acts on the lid-side second component 36 and the body-side second component 17, which are the internal components of the container 1, thereby preventing deterioration, damage, etc., of the means (locking means 52, etc.) that hold the lid-side second component 36 and the body-side second component 17. Furthermore, when the lid 5 is in the upright open position, the second overlapping portion 71 and the protruding wall portion 28 of the lid 5 overlap (come into contact) vertically, which reduces or eliminates the load of the lid 5 acting on the connecting portion 6 (shaft portion 51 and bearing portion 66), thereby preventing deterioration, damage, etc., of the connecting portion 6. In addition, since the first overlapping portion 46 and the second overlapping portion 71 are connected to each other, their respective strengths and rigidity can be enhanced.

[0054] Furthermore, the embodiment is not limited to the description above, and may be implemented as follows, for example. Of course, other applications and modifications not exemplified below are also possible.

[0055] (a) In the above embodiment, the lid 5 is configured to be held in an upright open position where the upper surface of the lid 5 extends substantially vertically, but the lid 5 may be held in other open positions. However, even if the rear of the container 1 is positioned so as to be substantially in contact with a predetermined wall portion 82, it is desirable to be able to hold the lid 5 in an upright open position so that contact between the lid 5 held in the open position and the predetermined wall portion 82 is avoided, the burden when holding the lid 5 in the open position is minimized, and the loading and unloading of items is made as easy as possible. In addition, in the above embodiment, the lid 5 is configured not to be rotated outward from the upright open position, but it may be configured to be able to rotate. Furthermore, in the above embodiment, the lid 5 is configured to be held in an upright open position, but it may be configured to restrict displacement only toward the closed position. Furthermore, in the above embodiment, the lid 5 is held in place by displacing it downwards after it has been rotated from the closed position to the upright open position. However, the lid 5 may also be held in place by another restraining means (for example, a locking mechanism that is operated manually). However, in order to simplify the opening and closing operation of the lid 5 and the mechanism for holding the lid 5 in the upright open position, it is desirable to have a configuration that allows the lid 5 to be held or released simply by displacing the lid 5, which is in the upright open position, in a direction different from the opening and closing direction of the lid 5.

[0056] (b) In the above embodiment, the restricting means includes a connecting portion restricting mechanism that restricts the rotational displacement of the shaft portion 51 with the sliding portion 68 of the bearing portion 66, and a non-connecting portion restricting mechanism that clamps the (inner restricting wall portion 62 and outer restricting wall portion 64) of the restricting projection 61 with the inner support portion 69 (joint wall portion 41) and the shaft covering wall portion 48. However, only one of these mechanisms may be adopted. In addition, in the above embodiment, the protruding shaft portion 51 is provided on the lid 5 side and the bearing portion 66 is provided on the container body 2 side. However, it is also possible to provide the bearing portion on the lid 5 side and the shaft portion on the container body 2 side. In this case, with respect to the bearing portion, when the lid is in the upright open position, the sliding portion is positioned above the rotating portion. Furthermore, the first overlap portion 46, the second overlap portion 71, and the outer overlap portion 72 can be omitted. However, by providing these, the airtightness of the container 1 in the closed state is increased, and the load of the lid 5 in the closed position and the upright open position can be stably supported by the first component 16 on the main body side without placing any burden on the second component 36 on the lid side and the second component 17 on the main body side (the relative displacement in the rearward and left-right directions between the container body 2 and the lid 5 in the closed position can be restricted by the outward overlapping portion 72 without placing any burden on the mating protrusion 42 and the mating recess 24, or in cooperation with each other).

[0057] (c) In the above embodiment, the upper surface of the container body 2 is inclined downward toward the front, but it may also be configured to extend in a substantially horizontal direction. However, inclining the upper surface of the container body 2 makes it easier to see inside the container body 2 when the lid 5 is in the open position, and also makes it easier to put items in and take them out. Also, in the above embodiment, the upper surface of the lid 5 in the closed position extends in a substantially horizontal direction, but it may also be configured to be inclined downward toward the front, or to be slightly curved in a substantially arc shape in cross-section. However, by configuring the upper surface of the lid 5 in the closed position to extend in a substantially horizontal direction, when the lid 5 is in the closed position, the storage portion 3 is also formed relatively widely on the lid 5, making it possible to secure the storage space of the container 1 as wide as possible, and it is also possible to place items on the upper surface of the lid 5 in the closed position. In addition, a holding portion for holding a cooling agent or the like may be provided on the back side of the lid 5 or on the inner side of the container body 2. It is also possible to omit the pocket portion 73.

[0058] (d) In the above embodiment, the container 1 (first component 16 on the main body side, second component 17 on the main body side, first component 35 on the lid side, and second component 36 on the lid side) is made of polypropylene, but it may also be made of other resin materials such as polyethylene, PET, or polyamide. In addition, in the above embodiment, in order to improve the cooling and heat retention performance, the container body 2 and the lid 5 are made of a hollow two-layer structure, and an insulating material 8 is provided in the internal space 18 on the main body side and the internal space 37 on the lid side, but the insulating material 8 may be omitted, or the container body 2 and the lid 5 may be made of a single-layer structure. Furthermore, in the above embodiment, the container 1 is in the shape of a roughly rectangular box, but it is also possible to materialize it into a container that is, for example, roughly cylindrical, roughly semicircular in plan view (with the front corners having a relatively large radius), etc. In addition, an explanation of how to close the lid 5, such as "When closing the lid, lift the lid slightly upwards and then tilt it forward," may be written on the back side of the lid 5 (pocket portion 73, etc.).
