Description

[Technical field]

[0001] The present invention relates to a grip structure and a container equipped with the same. [Background technology]

[0002] Conventionally, containers for storing items are known. For example, the container described in Patent Document 1 is provided with a handle hole through which a user can insert his / her hand when lifting the container. When carrying the container, the user inserts his / her hand into the handle hole and grasps the handle portion of the container located above the handle hole. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 10-316139 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the container according to Patent Document 1 has an angular shape at the handle portion located above the handle hole. When a user grasps the handle, the angular portion of the container comes into contact with the user's palm and fingers. Since the load is concentrated on the angular portion, the angular portion cuts into the palm and fingers. This causes the user to feel pain and discomfort.

[0005] An object of one aspect of the present invention is to provide a container that is unlikely to cause pain or discomfort to a user when the user grips the grip portion. [Means for solving the problem]

[0006] In order to solve the above problems, a container according to one aspect of the present invention is a container capable of storing items therein, the container comprising: a bottom wall portion; a side wall portion extending upward from the bottom wall portion and forming a storage space together with the bottom wall portion; a handle hole provided in the side wall portion; and a grip portion provided in the side wall portion and formed above the handle hole, the grip portion including a lower wall extending toward the outside of the container and constituting a part of the handle hole, an inner vertical wall extending upward from the lower wall on the inner surface side of the container, and an intermediate wall extending from an upper end of the inner vertical wall toward the outside of the container. The container has an outer vertical wall extending upward from the intermediate wall on the outer surface side of the container, and an upper wall extending from the upper end of the outer vertical wall toward the inside of the container, wherein a connecting surface connecting the inner vertical wall and the lower wall, the surface located on the inner surface side of the container has a convex curved surface toward the inside of the container, or a sloping surface whose normal direction faces downward on the inner surface side of the container, and a connecting surface connecting the outer vertical wall and the upper wall, the surface located on the outer surface side of the container has a convex curved surface toward the outside of the container, or a sloping surface whose normal direction faces upward on the outer surface side of the container.

[0007] According to the above-mentioned configuration, when a user holds the grip portion to lift up the container, the grip portion has a convex curved or inclined surface that is held by the user, which makes it possible to provide a grip structure that does not cause discomfort to the user even when the user holds the grip portion.

[0008] In the above container, the grip portion may further include a plurality of lower connecting ribs connecting the lower wall, the intermediate wall, and the inner vertical wall.

[0009] According to the above configuration, it is possible to prevent a hand from being inserted into the space formed by the lower wall, the intermediate wall, and the inner vertical wall, and it is possible to guide the hand into the handle hole by moving the hand along the lower connecting rib. Therefore, it is possible to easily insert the hand into the handle hole. In addition, the lower connecting rib is a rib that connects the lower wall, the intermediate wall, and the inner vertical wall. Therefore, it is possible to prevent the lower wall, the intermediate wall, and the inner vertical wall from being deformed by an external force acting when the grip portion is grasped.

[0010] In the above-mentioned container, the grip portion may further have a plurality of upper connecting ribs connecting the upper wall, the intermediate wall, and the outer vertical wall, and at least one of the upper connecting ribs may be arranged in the same straight line as at least one of the lower connecting ribs.

[0011] According to the above configuration, the lower connecting rib and the upper connecting rib are arranged on the same straight line, so that the lower connecting rib and the upper connecting rib are formed as a continuous rib, which makes it possible to prevent the entire grip portion from being deformed by an external force acting when the grip portion is held.

[0012] In the above container, an end portion of the lower wall located on the outer surface side of the container may be configured to be located closer to the inner surface of the container than a surface of the outer vertical wall on the outer surface side of the container.

[0013] According to the above configuration, the grip portion has a shape that matches the way the user holds it in their hand, thereby achieving a grip structure that does not feel strange when the user holds the grip portion.

[0014] In the above-mentioned container, the side wall portion further includes a connection portion that connects each of both ends of the grip portion in the width direction of the side wall portion to the side wall portion, and the connection portion has an extended upper wall that connects the upper wall to the side wall portion, an extended lower wall that connects the lower wall to the side wall portion, and an extended outer vertical wall that connects the outer vertical wall, the extended upper wall, and the extended lower wall on the outer surface side of the container, and the connection surface that connects the extended outer vertical wall and the extended lower wall, and is located on the outer surface side of the container, may be configured to be a curved surface that is convex toward the outside of the container and has a curvature that gradually decreases toward the grip portion.

[0015] According to the above configuration, a container can be provided that is less likely to cause discomfort even if the hand moves through the handle hole and hits the surrounding joints, because the boundaries of the joints are curved.

[0016] A grip structure according to one embodiment of the present invention is a grip structure provided on a conveying tool, the grip structure having a first wall extending toward a first direction, a second wall extending from the first wall toward a third direction perpendicular to the first direction on a second direction side opposite to the first direction, a third wall extending from the third direction side of the second wall toward the first direction side, a fourth wall extending from the third wall toward the third direction side on the first direction side, and a fifth wall extending from the third direction side of the fourth wall toward the second direction side, a connecting surface connecting the second wall and the first wall, the surface located on the second direction side having a curved surface convex toward the second direction side, or an inclined surface whose normal direction is the second direction side and toward the fourth direction side opposite to the third direction, and a connecting surface connecting the fourth wall and the fifth wall, the surface located on the first direction side having a curved surface convex toward the first direction side, or an inclined surface whose normal direction is the first direction side and toward the third direction side. Effect of the Invention

[0017] According to one aspect of the present invention, a container can be provided that is unlikely to cause pain or discomfort to a user even when the user grips the grip portion. [Brief description of the drawings]

[0019] [Embodiment 1] Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS.

[0020] <Overview of Container 1> As shown in Fig. 1, the container 1 is a generally rectangular parallelepiped container that is open at the top. The container 1 is made of resin. The container 1 has a bottom wall portion 2 and a side wall portion 3. The container 1 may be a cylindrical container or the like.

[0021] The bottom wall portion 2 has a substantially rectangular shape in a plan view, and is located at the bottom of the container 1.

[0022] The side wall 3 extends upward from the periphery of the bottom wall 2. The side wall 3 and the bottom wall 2 are perpendicular to each other. A space for storing items is formed in the space formed by the bottom wall 2 and the side wall 3. A first flange 31 extending toward the outside of the container 1 is formed at the upper end of the side wall 3. A second flange 32 extending from the main body of the side wall 3 toward the outside of the container 1 is formed below the first flange 31. A third flange 33 extending toward the outside of the container 1 is formed at the lower end of the side wall 3. The side wall 3 may have only the first flange 31.

[0023] <Handle hole 4> The side wall 3 is provided with a handle hole 4. As shown in Fig. 2 and Fig. 3, the handle hole 4 is a substantially rectangular through-hole provided in the side wall 3. The shape of the handle hole 4 is not limited to this, and may be, for example, a circular shape. The handle hole 4 may be any hole through which a finger can be inserted.

[0024] <Grip part 5> 2 to 5, a grip portion 5 is provided above the handle hole 4. The grip portion 5 has a lower wall 51, an inner vertical wall 52, an intermediate wall 53, an outer vertical wall 54, an upper wall 55, a lower connecting rib 56, and an upper connecting rib 57.

[0025] As shown in FIG. 4, the lower wall 51 extends toward the outside of the container 1. More specifically, the lower wall 51 extends from the lower end of the inner vertical wall 52 in a direction perpendicular to the side wall portion 3. The lower wall 51 forms a part of the handle hole 4. More specifically, the lower surface of the lower wall 51 forms the upper part of the handle hole 4. The outer end of the lower wall 51 located on the outer surface side of the container 1 has a lower corner of the end chamfered to form a curved surface R1. The outer end of the lower wall 51 is located on the inner surface side of the container 1 relative to the outer vertical wall 54. It is sufficient that the outer end of the lower wall 51 is located on the inner surface side of the container 1 relative to the surface of the outer vertical wall 54 on the outer surface side of the container 1.

[0026] The inner vertical wall 52 extends in the up-down direction of the container 1. The surface of the inner vertical wall 52 on the inner surface side of the container 1 forms a part of the inner surface of the container 1. The inner vertical wall 52 connects the lower wall 51 and the intermediate wall 53 on the inner surface side of the container 1. More specifically, the inner vertical wall 52 extends upward from the inner end of the lower wall 51 of the container 1. The upper end of the inner vertical wall 52 is connected to the inner end of the intermediate wall 53.

[0027] The connection surface 52a connecting the inner vertical wall 52 and the lower wall 51 has a curved surface that is convex toward the inside of the container 1. Note that the connection surface 52a may be configured such that the surface located on the inner surface side of the container 1 has a curved surface that is convex toward the inside of the container 1.

[0028] The intermediate wall 53 extends from above the inner vertical wall 52 toward the outside of the container 1. More specifically, the intermediate wall 53 extends from the upper end of the inner vertical wall 52 in a direction perpendicular to the side wall portion 3. The intermediate wall 53 is provided so that the length in the direction in which the intermediate wall 53 extends is longer than the bottom wall 51. In other words, the outer end of the bottom wall 51 of the container 1 is located closer to the inner surface of the container 1 than the connection portion between the intermediate wall 53 and the outer vertical wall 54.

[0029] The outer vertical wall 54 extends in the up-down direction of the container 1. The outer vertical wall 54 is located closer to the outer surface of the container 1 than the inner vertical wall 52. The surface of the outer vertical wall 54 on the outer surface side of the container 1 forms part of the outer surface of the container 1. The outer vertical wall 54 connects the intermediate wall 53 and the upper wall 55. More specifically, the lower end of the outer vertical wall 54 is connected to the outer end of the intermediate wall 53 of the container 1. The upper end of the outer vertical wall 54 is connected to the outer end of the upper wall 55 of the container 1.

[0030] The connection surface 54a connecting the outer vertical wall 54 and the intermediate wall 53 has a curved surface that is convex toward the outside of the container 1. The connection surface 54b connecting the outer vertical wall 54 and the upper wall 55 has a curved surface that is convex toward the outside of the container 1. Note that the connection surfaces 54a and 54b may be configured such that the surfaces located on the outer surface side of the container 1 have a curved surface that is convex toward the outside of the container 1. The curvature of the connection surface 54b may be the same as or different from the curvature of the connection surface 52a.

[0031] The upper wall 55 extends from above the outer vertical wall 54 toward the inside of the container 1. More specifically, the upper wall 55 extends from the upper end of the outer vertical wall 54 in a direction perpendicular to the side wall portion 3. The upper wall 55 is provided so that its length in the extending direction is longer than that of the lower wall 51. The length of the upper wall 55 in the extending direction is approximately the same as that of the intermediate wall 53. The inner end of the upper wall 55 located inside the container 1 is located at approximately the same position as the surface of the inner vertical wall 52 located on the inner surface side of the container 1. The upper corner of the inner end of the upper wall 55 is chamfered and has a curved surface R2.

[0032] The grip portion 5 is formed to have an S-shaped cross section. By forming the cross section in this S-shaped shape, for example, when the grip portion 5 is molded from resin, the product can be removed without the mold getting caught on the walls of the grip portion 5 when the mold is opened.

[0033] As shown in FIG. 4 and FIG. 5, a plurality of lower connecting ribs 56 are provided in the space formed by the lower wall 51, the inner vertical wall 52, and the intermediate wall 53. The lower connecting ribs 56 connect the lower wall 51, the inner vertical wall 52, and the intermediate wall 53. More specifically, the lower connecting ribs 56 are ribs that connect the outer surfaces of the container 1 of the lower wall 51, the inner vertical wall 52, and the intermediate wall 53. The outer edge 56a of the container 1 of the lower connecting ribs 56 is an inclined surface that connects the outer end of the lower wall 51 and the outer vertical wall 54. More specifically, the outer edge 56a is an inclined surface whose normal direction faces downward toward the outer surface side of the container 1. The provision of the lower connecting ribs 56 can prevent the fingers from being erroneously inserted into the space formed by the lower wall 51, the inner vertical wall 52, and the intermediate wall 53 when gripping the grip portion 5. In addition, when inserting the hand into the handle hole 4, the user can guide the hand into the handle hole 4 by moving the hand along the lower connecting ribs 56. This makes it easier to insert the hand into the handle hole 4.

[0034] A plurality of upper connecting ribs 57 are provided in the space formed by the intermediate wall 53, the outer vertical wall 54, and the upper wall 55. The upper connecting ribs 57 connect the intermediate wall 53, the outer vertical wall 54, and the upper wall 55. More specifically, the upper connecting ribs 57 are ribs that connect the inner surfaces of the intermediate wall 53, the outer vertical wall 54, and the upper wall 55 of the container 1. The number of the upper connecting ribs 57 is the same as the number of the lower connecting ribs 56. The number of the upper connecting ribs 57 is not limited to this, and may be more or less than the number of the lower connecting ribs 56. The inner edge 57a of the upper connecting rib 57 is a surface that connects the inner end of the upper wall 55 and the inner vertical wall 52. By providing the upper connecting ribs 57, it is possible to prevent fingers from being erroneously inserted into the space formed by the intermediate wall 53, the outer vertical wall 54, and the upper wall 55 when gripping the grip portion 5.

[0035] As shown in FIG. 5, the lower connecting rib 56 and the upper connecting rib 57 are provided on the same straight line. More specifically, the lower connecting rib 56 and the upper connecting rib 57 are provided on the same straight line in a direction perpendicular to the lower wall 51. In other words, the lower connecting rib 56 and the upper connecting rib 57 are provided on the same straight line in a direction perpendicular to the upper wall 55. In this way, the lower connecting rib 56 and the upper connecting rib 57 are provided on the same straight line, thereby reinforcing the grip portion 5 as a series of ribs. Therefore, it is possible to prevent the grip portion 5 from being deformed by an external force acting when the grip portion 5 is held. It is only necessary that the lower connecting rib 56 and the upper connecting rib 57 are provided on the same straight line in a direction intersecting the lower wall 51 or the upper wall 55.

[0036] <Connection 6> 2 and 3, a connecting portion 6 is provided on each side of the grip portion 5. The connecting portion 6 has an extended lower wall 61, an extended outer vertical wall 62, an extended upper wall 63, a connecting rib 64, and a side wall 65.

[0037] The extended lower wall 61 is a portion that connects the lower wall 51 to the side wall portion 3. More specifically, the extended lower wall 61 connects an end portion of the lower wall 51 in the width direction of the side wall portion 3 to a second flange portion 32 provided on the side wall portion 3.

[0038] The extended upper wall 63 is a portion that connects the upper wall 55 and the side wall portion 3. More specifically, the extended upper wall 63 connects an end portion of the upper wall 55 in the width direction of the side wall portion 3 and a first flange portion 31 provided on the side wall portion 3.

[0039] The side wall 65 is a portion that connects the bottom wall 51, the inner vertical wall 52, the intermediate wall 53, the extended bottom wall 61, and the extended outer vertical wall 62. More specifically, the side wall 65 is a portion that connects ends of the bottom wall 51, the inner vertical wall 52, and the intermediate wall 53 in the width direction of the side wall portion 3, and ends of the extended bottom wall 61 and the extended outer vertical wall 62 on the grip portion 5 side in the width direction of the side wall portion 3. The side wall 65 is located closer to the inner surface of the container 1 than the extended outer vertical wall 62.

[0040] The extended outer vertical wall 62 is a portion extending from the outer vertical wall 54 in the width direction of the side wall portion 3. More specifically, the extended outer vertical wall 62 extends in the width direction of the side wall portion 3 from an end portion of the outer vertical wall 54 in the width direction of the side wall portion 3. A lower end of the extended outer vertical wall 62 is connected to the outer end of the extended lower wall 61. An upper end of the extended outer vertical wall 62 is connected to the outer end of the extended upper wall 63.

[0041] As shown in FIG. 6, the connection surface 62a connecting the extended outer vertical wall 62 and the extended lower wall 61 has a curved surface that is convex toward the outside of the container 1. The connection surface 62a may be configured such that the surface located on the outer surface side of the container 1 has a curved surface that is convex toward the outside of the container 1. The connection surface 62a is a curved surface whose curvature gradually decreases toward the grip portion 5. The connection surface 62a has a curved area that increases toward the grip portion 5. By gradually decreasing the curvature in this manner, a wide curved area can be secured at the boundary portion (connection surface 62a) of the connection portion 6. Therefore, even if the hand moves inside the handle hole 4 and hits the surrounding connection portion 6, the boundary portion of the connection portion 6 is formed with a wide curved surface, so that the user is less likely to feel uncomfortable.

[0042] The connection surface 62b connecting the extended outer vertical wall 62 and the extended upper wall 63 has a curved surface that is convex toward the outside of the container 1. The connection surface 62b may be configured so that the surface located on the outer surface side of the container 1 has a curved surface that is convex toward the outside of the container 1. The connection surface 62b is a curved surface whose curvature gradually decreases toward the grip portion 5. In addition, the range of the connection surface 62b that has the curved surface increases toward the grip portion 5.

[0043] The connection surface 62c connecting the extended outer vertical wall 62 and the side wall 65 has a curved surface that is convex toward the outside of the container 1. The connection surface 62d continuing from the connection surface 62a and connecting to the side wall 65 of the extended outer vertical wall 62 has a curved surface that is convex toward the outside of the container 1. Note that the connection surfaces 62c and 62d may be configured such that the surfaces located on the outer surface side of the container 1 have a curved surface that is convex toward the outside of the container 1.

[0044] The connection surface 61a connecting the extended lower wall 61 and the side wall 65 has a curved surface that is convex toward the outside of the container 1. Note that the connection surface 61a may be configured such that the surface located on the outer surface side of the container 1 has a curved surface that is convex toward the outside of the container 1.

[0045] As described above, the outer end of the lower wall 51 of the container 1 is located closer to the inner surface of the container 1 than the connection portion between the intermediate wall 53 and the outer vertical wall 54, and the outer edge 56a of the container 1 of the lower connecting rib 56 is an inclined surface (an inclined surface whose normal direction faces downward toward the outer surface side of the container 1) connecting the outer end of the lower wall 51 and the outer vertical wall 54, so that a step is likely to occur at the boundary between the grip portion 5 and the connection portion 6.

[0046] If the structure does not have a curved surface such as the connection surface 61a, the connection surface 62c, and the connection surface 62d, the step portion is likely to have an angular shape. However, in the present invention, by providing curved surfaces to the connection surface 61a, the connection surface 62c, and the connection surface 62d, it is possible to prevent the user from feeling uncomfortable even if the hand moves inside the handle hole 4 and hits the surrounding connection portion 6. In particular, the portion where the connection surface 62d is provided is a portion that is likely to be hit by the hand and is likely to have an angular shape. Therefore, by configuring the connection surface 62d to have a curved surface, it is possible to prevent the user from feeling uncomfortable.

[0047] 3, a connecting rib 64 is provided in a space formed on the inner surface side of the container 1 by the extended lower wall 61, the extended outer vertical wall 62, and the extended upper wall 63. The connecting rib 64 is a rib that connects the inner surfaces of the container 1 of the extended lower wall 61, the extended outer vertical wall 62, and the extended upper wall 63.

[0048] <Grip of grip portion 5> An example of how the user grips the grip portion 5 will be described. When the user grips the grip portion 5, the palm of the hand contacts the upper wall 55 and the outer vertical wall 54, and the user's fingers contact the lower wall 51 and the inner vertical wall 52. More specifically, the palm of the hand on the wrist side contacts the upper wall 55, and the palm of the hand on the finger side contacts the outer vertical wall 54. A third joint, which is a joint between the palm and the fingers, is located near the boundary (connection surface 54a) between the outer vertical wall 54 and the intermediate wall 53. The first and second joints of the fingers contact the lower wall 51 and the inner vertical wall 52. The user grips the grip portion 5 in this manner.

[0049] Generally, when a user grasps the hand, the fingers move around the third joint toward the inside of the hand rather than the palm. Therefore, when the user grasps the grip portion 5, the user's fingers move around the third joint toward the inside of the container 1. In this way, the user grasps the lower wall 51 and the inner vertical wall 52 of the grip portion 5 with the fingers. In other words, when attempting to grasp the grip portion 5, the user's fingers move around toward the inside of the container 1 rather than the outer vertical wall 54. The outer end of the lower wall 51 located on the outer surface side of the container 1 is located on the inner surface side of the container 1 rather than the surface of the outer vertical wall 54 on the outer surface side of the container 1, so that the grip structure is adapted to the way the user grasps the hand. Therefore, the user can grasp the grip portion 5 without any discomfort.

[0050] The interval between the upper wall 55 and the intermediate wall 53 is set to be larger than the interval between the lower wall 51 and the intermediate wall 53. The intermediate wall 53 is located on the lower wall 51 side. In other words, the length of the inner vertical wall 52 in the vertical extension direction is shorter than the length of the outer vertical wall 54 in the vertical extension direction. The position of the intermediate wall 53 can be appropriately changed depending on the size of the container 1, the size of the grip part 5, etc. For example, in the case of a large container 1 with a large storage capacity, the grip part 5 is to be gripped with the palm of the hand, so the position of the intermediate wall 53 is located on the lower wall 51 side. This allows the area of ​​the outer vertical wall 54 that the palm of the hand touches to be sufficiently secured, and the user can firmly grip the grip part 5. On the other hand, in the case of a small container 1 with a small storage capacity, the user tries to grip the container 1 with the fingertips, so the intermediate wall 53 is located on the upper wall 55 side. This allows the area of ​​the inner vertical wall 52 that the fingertips touch to be sufficiently secured, and the user can grip the grip part 5 without discomfort.

[0051] (First Modification) A first modified example will be described with reference to Fig. 7. Fig. 7 is a diagram showing a first modified example of the grip part 5 included in the container 1 according to embodiment 1. In this modified example, the surfaces connected to the respective walls have inclined surfaces.

[0052] As shown in FIG. 7, the connection surface 521a connecting the inner vertical wall 521 and the lower wall 51 has an inclined surface. More specifically, the connection surface 521a is an inclined surface whose normal direction faces downward toward the inner surface side of the container 1. The connection surface 521b connecting the inner vertical wall 521 and the intermediate wall 53 has an inclined surface. More specifically, the connection surface 521b is an inclined surface whose normal direction faces upward toward the inner surface side of the container 1. Note that the connection surfaces 521a and 521b may be configured such that the surfaces located on the inner surface side of the container 1 have inclined surfaces whose normal direction faces the inner surface side of the container 1.

[0053] The connection surface 541a connecting the outer vertical wall 541 and the intermediate wall 53 has an inclined surface. More specifically, the connection surface 541a is an inclined surface whose normal direction faces downward toward the outer surface side of the container 1. The connection surface 541b connecting the outer vertical wall 541 and the upper wall 55 has an inclined surface. More specifically, the connection surface 541b is an inclined surface whose normal direction faces upward toward the outer surface side of the container 1. Note that the connection surfaces 541a and 541b may be configured such that the surfaces located on the outer surface side of the container 1 have inclined surfaces whose normal direction faces the outer surface side of the container 1.

[0054] (Second Modification) The second modified example will be described with reference to Fig. 8. Fig. 8 is a diagram showing a second modified example of the grip portion 5 included in the container 1 according to the first embodiment.

[0055] 8, an outer edge 561a of the container 1 of the lower connecting rib 561 forms a surface that connects the outer end of the lower wall 511 located on the outer surface side of the container 1 to the outer vertical wall 54. The outer end of the lower wall 511 is located closer to the inner surface of the container 1 than the outer edge 561a of the lower connecting rib 561. The outer edge 561a has a curved surface that is convex toward the outside of the container 1.

[0056] In this way, by positioning the end of the lower wall 511 closer to the inner surface of the container 1 than the outer edge 561a of the lower connecting rib 561, a curved surface can be formed on the outer edge 561a of the lower connecting rib 561. Furthermore, when a user grips the grip portion 5, the user's hand comes into contact with the outer edge 561a of the lower connecting rib 561. Since a curved surface is formed on the outer edge 561a, it is possible to prevent the user from feeling uncomfortable even when gripping the grip portion.

[0057] In addition, the outer end of the lower wall 511 has an upper corner chamfered to form a curved surface R3. The inner end of the upper wall 551 located on the inner surface side of the container 1 has a lower corner chamfered to form a curved surface R4. The connection surface 52b connecting the inner vertical wall 52 and the intermediate wall 53 has a curved surface that is convex toward the inside of the container 1.
