However, the above-mentioned conventional technique has the following problems. That is, in the "transport container" of Patent Document 1, as shown in FIG. 6, the cross-sectional shape around the handle hole is angular. For this reason, if the "transport container" is lifted by hand using its handle hole, the square-shaped part may bite into the hand and cause pain. In addition, the stored items of the "transport container" may be damaged by the collision with the square-shaped part.

The present invention has been made to solve the problems of the above-mentioned conventional techniques. That is, the problem is to provide a container in which a handle hole is formed and the aggression to the hands and stored items in the surrounding area is reduced.

The container in one aspect of the present invention has a bottom surface portion and a side surface portion provided on the upper side from the edge of the bottom surface portion, and the upper end of the side surface portion forms an opening, and the side surface portion has an opening. Along with the formation of the handle hole, the upper part of the side surface portion above the handle hole constitutes a grip portion having a width in the thickness direction of the side surface portion at least on the handle hole side and the upper end side. At least two of the four shoulders on the lower inner surface side, upper inner surface side, lower outer surface side, and upper outer surface side of the grip portion (lower inner surface side and lower outer surface side, or lower inner surface side and upper inner surface side, or The lower outer surface side and the upper outer surface side) form a convex curved surface when viewed in a cross-sectional view that vertically cuts the side surface portion.

In the container in the above embodiment, at least two of the four shoulders, which are the points where the user touches the container when the user lifts the container by using the grip portion, have a shape with low aggression to the user's hand. Has been done. Therefore, it is less likely to cause discomfort to the user when lifting the container. In addition, the rounded shoulders make the container less aggressive to the stored items.

Further, in the container in the above aspect, it is desirable that all four shoulder portions of the grip portion have a convex curved surface when viewed in a cross-sectional view in which the side surface portion is vertically cut. If this is the case, the effect of the rounded shoulders can be achieved regardless of how the container is lifted.

Further, in the container of any one of the above embodiments, the grip portion communicates the upper surface portion on the upper end side of the side surface portion, the lower surface portion on the handle hole side, and the upper surface portion and the lower surface portion on the inner surface side of the side surface portion. It has an inner surface portion, and a cavity portion that opens to the outer surface side is formed in the grip portion. In the cavity portion, a plurality of vertical ribs connecting the upper surface portion and the lower surface portion and vertical ribs are formed. It is desirable that the outer edge of the vertical rib has a convex curved surface toward the outer surface side. If this is the case, the strength of the grip portion can be ensured while saving the materials used. In addition, it is possible to suppress the entry of the user's hand into the cavity. In addition, the outer edge shape of the vertical rib is also a shape that is friendly to users and stored items.

Further, in the container of any one of the above embodiments, an overhanging portion is formed on the edge of the side surface portion facing the lower part of the handle hole, and the upper surface of the overhanging portion and the inner surface of the side surface portion form a protrusion. It is desirable that the shoulder portion has a convex curved surface when viewed in the cross-sectional view that vertically cuts the side surface portion. If this is the case, the shoulder on the inner surface side at the bottom of the handle hole also has a shape that is friendly to the user and stored items.

In the container in which the overhanging portion is formed, a folded portion extending downward is further formed at the outer end of the overhanging portion, and the shoulder portion formed by the upper surface of the overhanging portion and the outer surface of the folded portion forms the side surface portion. It is desirable to have a convex curved surface when viewed in the cross-sectional view to be cut vertically. If this is the case, the shoulder on the outer surface side at the bottom of the handle hole also has a shape that is friendly to the user and stored items.

In the container in which the overhanging portion is formed, the handle hole when the side surface portion is viewed from the front is further composed of the upper side, the lower side, and the turn portions on both sides connecting the upper side and the lower side with a curve. Is desirable. By doing so, the shoulder portion on the inner surface side of the turn portion can also be shaped to be friendly to the user and the stored items. Further, if the folded portion is also formed, the shoulder portion on the outer surface side of the turn portion can also be shaped to be friendly to the user and the stored items.

Further, in the container of any of the above embodiments, it is desirable that all of the above-mentioned convex curved surfaces are curved surfaces having a radius of curvature of 5 mm or more and 30 mm or less. As a result, the thickness of the grip portion can be kept within an appropriate range while ensuring the effect of the convex curved surface.

According to this configuration, a container is provided in which a handle hole is formed and the aggression to hands and stored items in the surrounding area is reduced.

It is a perspective view of the container which concerns on embodiment. It is sectional drawing of the short side side surface part of the container which concerns on embodiment. It is a perspective view of the cross-sectional part of FIG. It is a perspective view which shows the state in which the container which concerns on embodiment is stacked.

Hereinafter, embodiments embodying the present invention will be described in detail with reference to the accompanying drawings. This embodiment embodies the present invention as the container 10 shown in FIG. The container 10 of FIG. 1 has a rectangular bottom surface portion 2 and a long side side surface portion 3 and a short side side surface portion 4 provided on the upper side from the edge of the bottom surface portion 2. The container 10 has a substantially rectangular parallelepiped shape with the upper side open as a whole of the bottom surface portion 2, the long side side surface portion 3, and the short side side surface portion 4. Further, a substantially rectangular flange-shaped upper flange 5 is formed at the upper ends of the long side side surface portion 3 and the short side side surface portion 4. A flange-shaped lower flange 6 is formed at a position below the upper flange 5 on the long side side surface portion 3 and the short side side surface portion 4. The lower flange 6 is located between the upper flange 5 and the bottom surface portion 2.

In the container 10 shown in FIG. 1, a handle hole 7 is formed in the short side side surface portion 4. The handle hole 7 is a through hole in which a part of the short side side surface portion 4 is hollowed out in a window shape. In the short side side surface portion 4, the handle hole 7 is provided at a position in the center in the left-right direction and slightly above the center in the up-down direction. The portion above the handle hole 7 in the short side side surface portion 4 is the grip portion 8. A person can lift the container 10 by inserting a fingertip into the handle hole 7 and grasping the grip portion 8.

A cross-sectional view of the short side side surface portion 4 is shown in FIG. FIG. 2 shows a vertical cross section of the short side side surface portion 4 at the position where the handle hole 7 and the grip portion 8 are formed. As shown in FIG. 2, the grip portion 8 has a certain size in both the vertical direction and the width direction (thickness direction of the short side side surface portion 4) in the drawing. The size W in the width direction of the grip portion 8 is larger than the thickness of the short side side surface portion 4 itself, and is approximately the same as the width of the upper flange 5 shown in FIG. The vertical size H of the grip portion 8 is approximately the same as the width direction size W. This is slightly smaller than the distance between the upper flange 5 and the lower flange 6. As a result, the grip portion 8 is thick enough to be easily grasped by a human hand. The opening of the container 10 of the present embodiment is at the level indicated by the arrow C in FIG. This is a portion surrounded by the upper ends of the long side side surface portion 3 and the short side side surface portion 4. FIG. 3 shows a perspective view of the cross-sectional portion of FIG.

As shown in FIGS. 2 and 3, the four shoulders of the grip portion 8 in the cross-sectional view, that is, the inner upper shoulder 11, the inner lower shoulder 12, the outer upper shoulder 13, and the outer lower shoulder 14 are all at right angles. It is said to be a convex curved surface. Due to these four shoulders, the cross-sectional shape of the grip portion 8 is the upper surface portion 15 (upper end side of the short side side surface portion 4), the lower surface portion 16 (handle hole 7 side), and the inner surface portion 17 (short side side surface portion 4). The shape is such that the inner surface side) and the outer surface portion 18 (the outer surface side of the short side side surface portion 4) are smoothly connected. As a result, the burden on the hand due to the shoulder portion when the user grips the grip portion 8 by hand is reduced. In addition, the aggression of the shoulder portion to the stored items of the container 10 is also reduced. It is desirable that the radius of curvature of these convex curved surfaces is within the range of 5 mm or more and 30 mm or less (more preferably, 5 mm or more and 20 mm or less). This is because if the radius of curvature is too small, the effect is small, while if the radius of curvature is too large, it is difficult to keep the thickness of the grip portion 8 within an appropriate range.

As further shown in FIGS. 2 and 3, a hollow portion 20 is formed inside the grip portion 8. The cavity 20 is open toward the outer surface 18. The hollow portion 20 secures the thickness of the grip portion 8 to some extent, and suppresses the amount of the resin material required for manufacturing the container 10.

A lateral rib 21 is formed inside the cavity 20. Further, as shown in FIG. 3, a vertical rib 23 is also formed inside the cavity 20. The vertical rib 23 connects the upper surface portion 15 and the lower surface portion 16 inside the cavity portion 20. The outer edge of the vertical rib 23 has a curved surface that is convex toward the outer surface side. As can be seen from FIG. 1, a plurality of vertical ribs 23 are formed in the cavity 20. The horizontal rib 21 connects the vertical ribs 23 to each other inside the cavity 20. The horizontal ribs 21 and the vertical ribs 23 make it difficult for the fingertips to enter the hollow portion 20 when the grip portion 8 is grasped by hand. Further, the strength of the grip portion 8 whose inside is the hollow portion 20 is secured.

As further shown in FIG. 2, an overhanging portion 9 overhanging outward is formed on the edge of the short side side surface portion 4 facing the lower part of the handle hole 7. Further, a folded-back portion 22 extending downward is formed at the outer end of the overhanging portion 9. The shoulder portion 19 formed by the upper surface of the overhanging portion 9 and the inner surface of the short side side surface portion 4 and the shoulder portion 24 formed by the upper surface of the overhanging portion 9 and the outer surface of the folded portion 22 are all of the above-mentioned grip portion 8. Like the shoulders, it has a convex curved surface. As a result, even the lower part of the handle hole 7 has a shape that is gentle on the user's hand and stored items.

Returning to FIG. 1, the shape of the handle hole 7 itself will be described. The handle hole 7 is formed in a shape composed of an upper side 25, a lower side 26, and turn portions 27 on both sides in a state where the short side side surface portion 4 is viewed from the front. The turn portion 27 has a shape that connects the upper side 25 and the lower side 26 with an outward curve. The upper side 25 corresponds to the lower end (lower surface portion 16, inner lower shoulder 12, outer lower shoulder 14) of the grip portion 8 described above. The lower side 26 corresponds to the above-mentioned overhanging portion 9 and shoulder portions 19 and 24. Here, also in the turn portion 27, a convex curved shoulder portion is formed on the outer surface side in which the outer lower shoulder 14 of the upper side 25 and the shoulder portion 24 of the lower side 26 are continuously connected. Similarly, on the inner surface side, a convex curved shoulder portion is formed in which the inner lower shoulder 12 of the upper side 25 and the shoulder portion 19 of the lower side 26 are continuously connected. As a result, the shape is gentle to the user's hands and stored items not only at the upper and lower parts of the handle hole 7 but also at any place including the turn portion 27.

In the turn portion 27, the portion between the outer lower shoulder 14 on the upper side 25 and the shoulder portion 24 on the lower side 26 may be a gradually changing portion in which the radius of curvature of the convex curved surface gradually changes. For example, when the radius of curvature of the shoulder portion 24 is smaller than the radius of curvature of the outer lower shoulder 14, the gradually changing portion has a shape in which the radius of curvature gradually decreases from the outer lower shoulder 14 side to the shoulder portion 24 side. Is desirable. In this case, the radius of curvature of the convex curved surface of the outer lower shoulder 14 and the shoulder portion 24 may be at least within the range of 5 mm or more and 30 mm or less (more preferably 5 mm or more and 20 mm or less).

Further, the container 10 of the present embodiment can be stacked in a plurality of layers. FIG. 4 shows a state in which three containers 10 are stacked. In the one shown in FIG. 4, the bottom container 10 (101) and the middle container 10 (102) are stacked in a state of being rotated by 180 ° from each other. Therefore, the upper container 10 (102) is in a state of entering the storage space of the lower container 10 (101). Such stacking is possible when the lower container 10 (101) is empty. By that amount, the height dimension of the entire stack can be kept small.

On the other hand, the middle container 10 (102) and the uppermost container 10 (103) are stacked in the same direction. Therefore, the upper container 10 (103) does not enter the storage space of the lower container 10 (102). When the stored items are actually contained in the lower container 10 (102), such stacking is performed. As a result, the stored items in the lower container 10 are protected. Further, in a situation where a large number of containers 10 are stacked, it is possible to easily grasp which stage of the container 10 is empty or contains a stored item.

As described in detail above, according to the present embodiment, the user can make the shoulder portion of each portion a convex curved surface in the handle hole 7 and the grip portion 8 of the short side side surface portion 4 of the container 10. A container 10 that is gentle on the hands and stored items has been realized. Here, for example, all of the four shoulders of the grip portion 8 do not have to be the above-mentioned convex curved surfaces.

For example, of the inner upper shoulder 11, inner lower shoulder 12, outer upper shoulder 13, and outer lower shoulder 14, at least the inner lower shoulder 12 and the outer lower shoulder 14 may have a convex curved surface. .. Even in such an embodiment, it is sufficient for a situation in which a hand is deeply inserted into the handle holes 7 of both short side side surface portions 4 to support the grip portion 8 from below and lift the container 10. Further, at least the inner upper shoulder 11 and the inner lower shoulder 12 may have a convex curved surface. Even in such an embodiment, a situation in which only the grip portion 8 of one short side side surface portion 4 is supported by hand and the empty container 10 is lifted while the other short side side surface portion 4 is hung downward. Is enough for. Alternatively, at least the outer upper shoulder 13 and the outer lower shoulder 14 may have a convex curved surface. Even in such an embodiment, it is sufficient for a situation in which the container 10 is lifted while sandwiching the container 10 with a shallow hand attached to the handle holes 7 of both short side side surface portions 4.

Of course, if all four shoulders have a convex curved surface, all situations can be dealt with. Similarly, in the lower side 26 of the handle hole 7, only the shoulder portion 19 of the shoulder portions 19 and 24 may have a convex curved surface.

It should be noted that the present embodiment is merely an example and does not limit the present invention in any way. Therefore, as a matter of course, the present invention can be improved and modified in various ways without departing from the gist of the present invention. For example, the overall shape of the container is not limited to the rectangle as shown in the figure, but may be a square or any other polygon. Further, a shape other than a polygon such as a circle or an oval may be used. Further, even when the overall shape of the container is rectangular, the handle hole 7 and the grip portion 8 may be provided on the long side side surface portion 3 instead of being provided on the short side side surface portion 4. Further, the in-plane shape of the handle hole 7 is not limited to an oval shape as shown in the figure, but may be a rectangle with rounded four corners. The vertical side of the handle hole 7 in this case also corresponds to the turn portion connecting the upper side and the lower side with a curved line.
