Japanese Patent No. 2579855

By the way, in the container described in Patent Document 1, the handle portion is formed only by providing a through hole in the substantially plate-shaped side wall portion, and when a relatively heavy article is accommodated in the container, There is a concern that the burden on the hand will increase when the handle is held by the hand and carried. Also, in the container nesting state, the outer side of the through hole of the upper container is blocked by the side wall of the lower container, or the inner side of the through hole of the lower container is blocked by the side wall of the upper container. In such a case, not only is it impossible to insert a fingertip into the through-hole, but it is also difficult to put a fingertip on the upper edge of the through-hole, and the handle may not function well. .

SUMMARY OF THE INVENTION The present invention has been made to solve the problems exemplified above, and an object of the present invention is to provide a container that can be easily held.

Hereinafter, each means suitable for solving the above problems will be described separately. It should be noted that actions and effects specific to the corresponding means will be added as necessary.

Means 1. A container comprising a bottom wall-constituting portion that is substantially rectangular in plan view and side wall portions extending upward from each side portion of the bottom wall-constituting portion, and having a storage space capable of accommodating an article therein,
The side wall portion includes an overhang portion provided so as to outwardly displace or deform a portion including an upper edge portion of the inner surface constituting wall portion constituting the inner surface of the side wall portion, and a lower edge of the overhang portion. a holding portion projecting inward from the portion, and a through hole penetrating the inner surface constituting wall portion adjacent to the lower side of the holding portion is provided ,
An outer edge side of the gripping portion is connected to the projecting portion,
The grip portion is provided so as to protrude inward from a lower edge portion of the overhanging portion located outside the inner surface constituting wall portion,
A container , wherein a boundary portion where the holding portion and the projecting portion are connected has a generally arcuate cross section or a flattened shape.

According to Means 1, in a configuration in which an operator can insert a finger into the through-hole and grip the upper portion (handle portion) of the through-hole, the grip portion constituting the upper edge portion of the through-hole is the inner surface constituting wall portion. It protrudes inward from the lower edge of the overhanging portion positioned outwardly from the outermost portion. For this reason, for example, compared to a structure in which a through hole is simply provided in the side wall portion (inner surface constituting wall portion) and the upper portion thereof is held as a handle portion, the handle portion can be gripped with fingers from the lower side. The area of the lower surface of the hand can be increased. Therefore, it is possible to prevent a local load from being applied to the hand that lifts the container, thereby reducing the burden on the hand. As a result, it is possible to improve the easiness of holding the container, and to improve the workability when carrying the container by gripping the handle. In addition, it is possible to eliminate corners as much as possible from the part that contacts the gripping hand, thereby further achieving the effect of making the container easier to hold.

For example, in the case of providing an upper flange portion that extends outward from the upper side portion of the side wall portion, the portion of the upper flange portion that corresponds to the overhang portion is such that the upper edge portion of the inner surface constituting wall portion extends outward. If the shape is notched due to being displaced or deformed, for example, a through hole is provided in the side wall portion (inner surface constituting wall portion) without providing an overhang portion, and the Compared to the configuration in which a grip portion is provided that protrudes outward from the upper edge portion of the through hole and faces the lower surface of the upper flange portion, the structure of the mold for molding the container can be simplified. In addition, since the outer edge side of the gripping portion is connected to the protruding portion, the strength of the outer edge side of the gripping portion can be increased, and when the container is lifted by placing a finger on the lower surface of the gripping portion, the container can be gripped. It is possible to prevent situations such as deformation and damage of the part.

Means 2. Nesting of the containers is possible by stacking the containers so that the upper container is inserted into the accommodation space of the lower container,
The container according to means 1, wherein the inner edge of the gripping portion is flush with the inner surface of the inner surface constituting wall portion, or positioned outward from the inner surface of the inner surface constituting wall portion.

According to the means 2, by nesting containers, it is possible to improve transportation efficiency and storage efficiency. Furthermore, it is possible to prevent the gripping portion from interfering with the nesting, thereby enabling more efficient nesting and preventing damage to the gripping portion.

In addition, it is also possible that "in the container nesting state, the lower edge of the side wall of the upper container is located below the lower edge of the through hole of the lower container". In this case, the nesting efficiency can be improved (the height of the plurality of nested containers is minimized to improve the transport efficiency and the like). Furthermore, when this configuration is adopted, the inner side of the through hole of the lower container is closed by the side wall of the upper container when the containers are nested. Since the gripping portion is provided adjacent to the upper side (continuous to the upper edge of the through hole), a finger trying to pass through the through hole of the lower container hits the side wall of the upper container. Even so, the plurality of nested containers can be lifted by placing a fingertip on the lower surface of the grip portion of the lower container having a predetermined area.

Further, it is also possible that "in the container nesting state, the lower edge of the through hole of the upper container is positioned below the upper edge of the side wall of the lower container", and It is also stated that "in the container nesting state, the upper edge of the through hole (the lower surface of the grip portion) of the upper container is located below the upper side of the side wall of the lower container." good. In this case, the nesting efficiency can be further improved. Further, when this configuration is adopted, in the container nesting state, at least the lower portion of the through hole of the upper container is accommodated inside the lower container. By providing the protruding portion at the position, it is possible to have a positional relationship in which the inner surface of the protruding portion of the lower container can be viewed from the inner side of the upper container through the through hole of the upper container. A space into which the operator's fingertips can be inserted can be secured below the gripping portion (between the gripping portion of the upper container and the gripping portion of the lower container). Therefore, when the upper container is taken out one by one from the containers in the nesting state, the liquid is passed from the inside of the upper container through the through hole to the upper edge of the through hole of the upper container and the lower surface of the gripping portion. You can use your fingertips to lift the upper container.

However, "in the container nesting state, the holding portion of the upper container and the holding portion of the lower container are vertically separated". As a result, a space into which a fingertip can be inserted can be reliably secured between the gripping portion of the container on the upper side and the gripping portion of the container on the lower side.

Means 3. a side plate portion protruding inward from a side edge portion of the overhanging portion, the side plate portion being connected to the inner surface forming wall portion;
3. The container according to means 1 or 2, wherein the gripping portion protrudes inward from the lower edge portion of the projecting portion and is connected to the inner surface forming wall portion.

Means 4. Means 1 to 3, wherein the lower surface side of the gripping portion is curved so that the central portion of the gripping portion protrudes downward in the lateral width direction of the side wall portion on which the gripping portion is provided. The container according to any one of

According to the means 4, the shape of the lower surface of the grip part can be made to match the alignment of the fingers when the hand is naturally grasped, and the upper part (handle part) of the through hole can be made more visible through the through hole. can be made easier to hold.

Means 5. An upper flange portion extending outward from an upper edge portion of the inner surface constituting wall portion,
Regarding the portion of the upper flange portion that extends outward from at least the upper edge portion of the overhanging portion, the upper flange portion includes a base portion and an inclined portion that slopes outward from the base portion downward. 5. The container according to any one of means 1 to 4, wherein a boundary portion between the base portion and the inclined portion has a substantially arcuate cross section.

According to the means 5, it is possible to eliminate corners as much as possible from the part where the fingertip is inserted into the through-hole and touch the hand gripping the upper part (handle part) of the through-hole, and to increase the contact area with the hand. . Therefore, the effect of making the container easier to hold is further exhibited.

In addition, as shown in FIG. 1 and the like, rectangular openings are provided in a matrix in the long side wall portion 3, the short side wall portion 4, and the bottom wall forming portion 2, thereby reducing weight. It is designed to

As described in detail above, according to the present embodiment, in a configuration in which an operator can insert a finger into the through-hole 14 and grasp the upper portion (handle portion 15) of the through-hole 14, the upper edge of the through-hole 14 A gripping portion 13 forming a part is provided so as to protrude inward from a lower edge portion of an overhanging portion 12 located outside the inner surface forming wall portion 11 (see FIG. 5). For this reason, for example, compared to a configuration in which a through hole is simply provided in the short side wall portion 4 (inner surface forming wall portion 11) and the upper portion thereof is gripped as a handle portion, the fingers of the handle portion 15 are held. It is possible to increase the area of the lower surface of the handle part 15 that can be hung from the lower side. Therefore, it is possible to prevent a local load from being applied to the hand lifting the container 1, thereby reducing the burden on the hand. As a result, it is possible to improve the easiness of holding the container 1, and to improve the workability when carrying the container 1 by gripping the handle portion 15, for example.

In addition, for example, a through hole is provided in the short side wall portion 4 (inner surface forming wall portion 11) without providing the projecting portion 12, and the lower surface of the upper flange portion protrudes outward from the upper edge portion of the through hole. Compared to the configuration in which a gripping portion facing is provided, it is possible to simplify the mold structure for molding the container 1 (especially the portion between the upper flange portion 17 and the gripping portion). In addition, since the outer edge side of the gripping portion 13 is connected to the overhanging portion 12, the strength of the outer edge portion side of the gripping portion 13 can be increased, and the container 1 can be lifted by placing a finger on the lower surface of the gripping portion 13. It is possible to prevent situations such as deformation and damage of the grip portion 13 in such a case.

In addition, the container 1 is configured to be nestable, so that it is possible to improve the transportation efficiency and storage efficiency of the container 1 that does not contain articles. Furthermore, the inner edge of the grip portion 13 is located outside (or flush with) the inner surface of the inner surface forming wall portion 11 . For this reason, it is possible to avoid the grip portion 13 from interfering with nesting, and it is possible to perform nesting more efficiently (by making the insertion length of the upper container 1 into the lower container 1 deeper). Moreover, damage to the grip portion 13 can be suppressed.

In addition, in the nesting state of the containers 1, the lower edge of the through hole 14 of the upper container 1 is positioned below the upper side of the short side wall 4 of the lower container 1 (see FIG. 7). ). As a result, the nesting efficiency can be improved (the height of the plurality of containers 1 in the nested state is minimized to improve the transport efficiency and the like). Furthermore, in the nesting state of the containers 1, the inner side of the through hole 14 of the lower container 1 is closed by the short side wall portion 4 (inner surface forming wall portion 11) of the upper container 1, but as described above, , the gripping portion 13 is provided adjacent to the upper side of the through hole 14 (continuously connected to the upper edge of the through hole 14), so that the finger trying to pass through the through hole 14 of the container 1 on the lower side can Even if the container hits the short side wall portion 4 of the upper container 1, it is possible to lift a plurality of nested containers 1 by placing a fingertip on the lower surface of the grip portion 13 of the lower container 1 having a predetermined area. can be done.

In addition, in this embodiment, when the containers 1 are in the nesting state, the upper edge of the through hole 14 of the upper container 1 is almost at the same height as the upper side of the short side wall 4 of the lower container 1. , and most of the through holes 14 of the upper container 1 are accommodated inside the lower container 1 . In this respect, as described above, since the overhanging portion 12 is provided above the through hole 14 , from the inside of the upper container 1 , through the through hole 14 of the upper container 1 , the lower side can be reached. The positional relationship is such that the inner surface of the overhanging portion 12 of the container 1 faces. Therefore, a space into which the operator's fingertips can be inserted is secured below the gripping portion 13 of the upper container 1 (between the gripping portion 13 of the upper container 1 and the gripping portion 13 of the lower container 1). be able to. Therefore, when the upper containers 1 of the containers 1 in the nesting state are taken out one by one, the upper edge of the through hole 14 of the upper container 1 and the upper edge of the through hole 14 of the upper container 1 and , the upper container 1 can be lifted by putting a fingertip on the lower surface of the grip portion 13 .

In addition, the projecting portion 12 is provided in a range including the central portion in the width direction of the short side wall portion 4 on which the projecting portion 12 is provided, and includes each side portion of the short side wall portion 4. The site is a site where the projecting portion 12 is not provided. That is, when the containers 1 are nested, the inner surface of the short side wall portion 4 (inner surface forming wall portion 11) of the lower container 1 moves outward (in the longitudinal width direction of the container 1) of the upper container 1. However, by providing a portion where the overhanging portion 12 is not provided in the width direction of the short side wall portion 4 as described above, the short side wall portion 4 (inner surface constituting wall portion 11) can be provided with a portion where the inner surface of 11) extends substantially flush to the upper side of the short side wall portion 4 . Therefore, when nesting the containers 1, the outer surface of the short side wall portion 4 of the upper container 1 is moved from the upper side portion of the short side wall portion 4 of the lower container 1 to the inner surface of the short side wall portion 4. The upper container 1 can be inserted into the lower container 1 while keeping the upper container 1 along the lower container 1, and the lower surface of the upper container 1 is relatively displaced to a position where it faces and abuts the upper surface of the grip portion 13 of the lower container 1. It is possible to avoid situations such as Therefore, it is possible to improve the workability when nesting the containers 1 or the like.

Furthermore, the lower surface side of the gripping portion 13 is curved in the lateral width direction of the short-side side wall portion 4 on which the gripping portion 13 is provided so that the central portion of the gripping portion 13 protrudes downward. Therefore, the shape of the lower surface of the grip portion 13 can be made to match the alignment of the fingers when the hand is naturally gripped, and the upper portion (handle portion 15) of the through hole 14 can be grasped through the through hole 14. It can be made easier to hold.

In addition, the boundary portion between the grip portion 13 and the projecting portion 12 has a substantially arcuate cross section. Furthermore, the upper flange portion 17 extending outward from the upper edge portion of the overhang portion 12 is formed by a base portion 18 extending outward from the upper edge portion of the overhang portion 12 and a base portion 18 extending outward from the outer edge portion of the base portion 18 . and a sloped portion 19 that slopes more downward than the base portion 18, and the boundary portion between the base portion 18 and the sloped portion 19 has a substantially arcuate cross section. For this reason, it is possible to eliminate corners as much as possible from the part where the fingertips are inserted into the through-hole 14 and touch the upper part (handle part 15) of the through-hole 14, and to increase the contact area with the hand. . Therefore, the effect of making the container 1 easier to hold is further exhibited.

In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other applications and modifications not exemplified below are naturally possible.

(a) In the above embodiment, the container 1 is embodied in a nestable container, but for example, it can be applied to a container capable of both nesting and stacking (stacking of containers containing articles). It is possible. For example, the container 31 shown in Figs. and a receiving portion 36 provided on the inner surface side of 32 and 33 .

As shown in FIGS. 10 and 11, the upper container 31 is horizontally rotated 180 degrees with respect to the lower container 31, and stacked vertically so that the support portion 35 of the upper container 31 is positioned on the lower side. is inserted into the receptacle 36 of the container 31, and nesting of the container 31 is performed. On the other hand, by stacking the containers 31 vertically in the same direction, the support portion 35 of the upper container 31 is not inserted into the receiving portion 36 of the lower container 31, and the upper flange of the long side wall portion 32 is inserted. It is supported in contact with the upper surface of the portion 34, or is inserted into a stacking receiving portion 37 provided adjacent to the receiving portion 36 so that the bottom surface is located above the bottom surface of the receiving portion 36, and is attached to the bottom surface of the receiving portion 36. Stacking is performed by abutting and supporting.

9 to 11, the inner surface forming wall portion 38 forming the inner surface of the short side wall portion 33 is provided so as to displace the portion including the central portion of the upper edge portion outward. a projecting portion 39, a gripping portion 40 protruding inward from the lower edge of the projecting portion 39 and connected to the inner surface constituting wall portion 38, and a transparent penetrating through the inner surface constituting wall portion 38 adjacent to the lower side of the gripping portion 40. A hole 41 is provided. By providing the gripping portion 40 in this way, it is possible to secure as large an area as possible for the portion corresponding to the lower surface of the upper portion of the through-hole 41 (the handle portion 42), so that the container can be held by holding the handle portion 42. 31 can be made easy to carry. 9, etc., the overhanging portion 39 of the container 31 is configured in a substantially flat plate shape by displacing a portion including the upper edge portion of the inner surface forming wall portion 38 outward. A side plate portion 43 is provided that protrudes inward from the edge portion and is connected to the inner surface forming wall portion 38 . Also, the container 31 is designed not to have a handle as described in the above embodiments.

Furthermore, in the nesting state of the containers 31, the inner side of the through hole 41 of the lower container 31 is blocked by the short side wall portion 33 of the upper container 31. Even without it, the nested containers 31 can be carried together by placing a finger on the lower surface of the grip portion 40 of the lower container 31 .

(b) How much the upper container 1 is inserted into the housing space 5 of the lower container 1 in the nesting state can also be changed as appropriate. For example, in the nesting state of the containers 1 , the upper edge of the through hole 14 (the lower surface of the grip portion 13 ) of the upper container 1 is positioned below the upper side of the short side wall 4 of the lower container 1 . It is also possible to let That is, by providing the overhanging portion 12 as in the above embodiment, the lower surface of the grip portion 13 of the upper container 1 is inserted into the overhanging portion 12 of the lower container 1, and the upper It becomes possible to insert the grip portion 13 of the container 1 into the inside of the lower container 1 .

When the upper container 1 is taken out one by one from the nested containers 1, the upper container 1 is removed from the storage space 5 of the upper container 1 through the through hole 14 of the upper container 1. When the upper container 1 is lifted by putting a finger on the lower surface of the gripping portion 13 of the upper row, the gripping portion 13 of the upper container 1 and the lower container 1 are separated from each other in the nesting state of the containers 1. It is assumed that a space (a space into which a fingertip can be inserted) is formed between it and the grip portion 13 (in the above example, it is ensured by the limiting projections 21 and limiting ribs 22). It should be noted that it is also possible to embody a container in which nesting is not possible (stacking may or may not be possible).

(c) In the above embodiment, the inner edge of the grip portion 13 is connected to the inner surface constituting wall portion 11, but the part of the inner surface constituting wall portion 11 that is connected to the grip portion 13 is omitted, The inner edge of the grip portion 13 is located outside the inner surface of the inner surface constituting wall portion 11, and the inner edge of the grip portion 13 is located inside the inner surface of the inner surface constituting wall portion 11. good too. However, if the gripping portion 13 protrudes inward from the inner surface forming wall portion 11, the lower surface side of the upper container 1 may be caught by the gripping portion 13 of the lower container when the containers 1 are nested. Therefore, it is desirable that the inner edge of the grip portion 13 is flush with the inner surface of the inner surface forming wall portion 11 or is positioned on the outer side. A reinforcing rib may be provided to obliquely connect the inner surface of the projecting portion 12 and the upper surface of the grip portion 13 .
