  By the way, in the technique described in Patent Document 1, it is necessary to engage or disengage the engaging portion and the engaged portion when closing or opening the lidded container. In other words, the lid member cannot be removed from the container main body simply by lifting the lid member attached to the container main body, and by pulling the lid member while holding the container main body in the vicinity of each engagement site, It is necessary to release the engaged state in order. When the lid member is mounted on the container body, the lid member is not simply placed on the upper side of the container body, but a force is applied in order to push the lid member into the container body in the vicinity of each engaging portion. It is necessary to match.

  In addition, as in Patent Document 2, when a label is attached to the lid member and the container main body, it is necessary to prepare the label separately, and when the container with the lid is closed or opened, the label is attached. It is necessary to peel it off. Therefore, there is a concern that the opening and closing workability of the lidded container will be lowered, and as a result, the transport efficiency will be lowered.

  The present invention has been made to solve the above-described problems, and its object is to prevent the lid member from inadvertently floating or dropping while suppressing a decrease in workability during opening and closing. An object of the present invention is to provide a container with a lid that can be used.

  In the following, each means suitable for solving the above-mentioned purpose will be described in terms of items. In addition, the effect etc. peculiar to the means to respond | correspond as needed are added.

Is supported on the upper surface of the flange portion, and the lower projection is in contact with or close to the inner peripheral surface of the housing portion,
The outer peripheral dimension of the lid member is configured to be smaller than the outer peripheral dimension of the flange portion ,
The lid member protrudes upward from the upper surface thereof, and when the container main body is placed on the upper surface of the lid member, the lid member includes an upper protrusion that prevents the horizontal displacement of the container main body placed on the upper surface,
The container with a lid , wherein a vent hole penetrating in the horizontal direction is formed in the upper protrusion .

  According to the means 1, the outer peripheral dimension of the lid member is configured to be smaller than the outer peripheral dimension of the flange portion, and the positional deviation of the lid member in the horizontal direction with respect to the container body is prevented by the lower protrusion, whereby the lid member The outer peripheral edge can be positioned closer to the inner peripheral side than the outer peripheral edge of the flange portion. With this configuration, it is possible to avoid a situation in which wind blowing from below the flange portion hits the lower surface of the lid member and the lid member is lifted. Further, for example, when the cover member protrudes to the outer peripheral side from the outer peripheral edge of the flange portion, a predetermined object or the like is applied to a portion that protrudes to the outer peripheral side from the flange portion of the cover member during transportation. Can be prevented from coming into contact and pushing up the lid member. Therefore, the lid member may be lifted or detached carelessly without providing an engaging means for engaging the lid member with the container body or a sealing means for sticking between the lid member and the container body. Such a situation can be suppressed. Further, compared to the case where the engaging means is provided, the manufacturing of the lidded container is not complicated, and the convenience during the opening / closing operation can be enhanced. Furthermore, compared with the case where the sealing means is adhered, the opening and closing workability of the lidded container can be improved, and the seal (such as an adhesive) is peeled off from the lid member or the container body. It is possible to avoid the possibility that the appearance, touch, hygiene and the like will be deteriorated.

Further, when the upper protrusion is provided on the lid member as in the means 1, the upper protrusion can be used as a positioning member for stacking, and the upper protrusion can be attached to and detached from the lid member or carried. It can be used as a handle for the occasion. However, there is a concern that by providing the upper protrusion protruding upward from the upper surface of the lid member, the lid member is likely to be affected by crosswinds and the like, and the lid member is likely to float or come off from the container body. Is done. On the other hand, according to this means 1, since the ventilation hole is formed in the upper protrusion, the air blown to the upper protrusion can be escaped from the ventilation hole. Therefore, the wind pressure which an upper side protrusion receives can be reduced, and the said malfunction can be suppressed as a result.

In the configuration in which the outer peripheral edge of the lid member is located on the inner peripheral side with respect to the outer peripheral edge of the flange portion as described above, it is difficult to put a finger on the outer peripheral edge of the lid member when removing the lid member. Since it can be used as a handle, it is possible to dramatically improve removal workability.

Mean 2. An overhanging portion extending substantially horizontally from the upper edge of the upper protrusion,

When the overhanging portion is provided as in the means 2, the strength of the upper protrusion can be increased, and the lid member can be attached and detached by placing a finger on the overhanging portion extending in the substantially horizontal direction. It becomes easier to open and close the attached container. However, there is a concern that the wind blows on the lower surface of the overhanging portion, so that the lid member easily floats or comes off from the container body. On the other hand, according to this means 2, since the upper surface ventilation hole is formed with respect to the overhang | projection part, the wind sprayed on the overhang | projection part can be escaped from an upper surface ventilation hole. Therefore, the wind pressure received by the overhanging portion can be reduced, and as a result, the above-described problems can be suppressed.

The overhanging portion may be overhanging from the upper protrusion to the outer peripheral side of the lid member. In this case, when attaching and detaching the lid member, a finger can be applied to the overhanging portion from the outer peripheral side of the lid member, force is easily applied, and the opening and closing workability of the lidded container is dramatically improved.

Means 3 . In the closed state of the opening of the receiving portion by the lid member, and the lid member and the flange portion, means 1, characterized in that are in contact continuously over whole outer circumferential edge of the cover member or the 2. A container with a lid according to 2 .

According to the means 3, it is possible to completely close the opening of the accommodating part, and it is possible to avoid a situation in which wind directly hits the lower surface of the lid member in the entire area of the lid member. Played.

Means 4 . The accommodating portion has a substantially square box shape opening upward, and the lid member has a substantially square plate shape corresponding to the accommodating portion,

According to the means 4 , by providing the upper protrusions corresponding to the four corners of the lid member, it is possible to increase the rigidity of the four corners that are relatively easily deformed and to suppress the deformation. Further, since the weights of the four corners of the lid member are increased, it is possible to suppress a situation in which the corner portion of the lid member is lifted when the lid member receives wind.

  Furthermore, the deformation of the lid member is more reliably suppressed by the cross rib. That is, it is possible to ensure sufficient strength to sufficiently support the lidded container placed on the upper side without deformation even when the lidded containers are stacked, as well as deformation during molding is suppressed. it can. Therefore, by preventing the deformation of the lid member, the upper surface of the flange portion and the lower surface of the lid member can be reliably brought into contact with each other, and wind blows into the gap between the two and the lid member floats from the container body. It is possible to prevent a situation where it is easy to come off.

  Hereinafter, an embodiment will be described with reference to the drawings. As shown in FIGS. 1 to 4 and the like, the lidded container 1 includes a container body 2 that can store articles, and a lid member 7 that can close an opening of the container body 2. The container body 2 includes a substantially square box-shaped storage portion 3 that opens upward, and a flange portion 4 that extends from the entire upper edge of the storage portion 3 toward the outer periphery of the opening. Formed. The container body 2 and the lid member 7 of this embodiment are made of polypropylene.

  As shown in FIG. 1, FIG. 5, etc., substantially L-shaped corner ribs 11 are provided on the upper surface of the lid member 7 so as to correspond to the four corners of the lid member 7. The corner rib 11 protrudes upward from the upper surface of the lid member 7 at a position slightly inside the outer peripheral edge of the lid member 7, and extends upward in a substantially L shape along the outer peripheral edge of the lid member 7. The vertical wall portion 12 as a portion, the protruding portion 13 extending from the upper edge portion of the vertical wall portion 12 to the outer peripheral side of the lid member 7, and the lower surface of the protruding portion 13 and the upper surface of the lid member 7 are connected. And a connecting portion 14. The leading edge of the overhang portion 13 is located on the inner peripheral side with respect to the outer peripheral edge of the lid member 7.

  As shown in FIG. 5, FIG. 8, and the like, the vertical wall portion 12 is formed with a ventilation hole 15 penetrating in the outer peripheral direction of the lid member 7. The overhanging portion 13 is formed with an upper surface ventilation hole 16 penetrating in the vertical direction. In the present embodiment, the ventilation hole 15 is formed to be continuous with the upper surface of the lid member 7 at the lower part of the vertical wall portion 12. Further, the upper surface ventilation hole 16 is formed at the same position as the ventilation hole 15 in the circumferential direction of the lid member 7.

  Further, as shown in FIG. 4 and the like, the lid member 7 protrudes downward from the lower surface of the lid member 7 at a position on the inner circumferential side with respect to the outer circumferential edge of the lid member 7, and extends along the outer circumferential edge of the lid member 7. Frame ribs 21 are provided as lower protrusions extending in a substantially rectangular frame shape. Further, cross ribs 22 extending in a cross shape so as to connect the diagonal corner portions of the frame rib 21 are provided.

  Then, as shown in FIGS. 6 to 8 and the like, by covering (attaching) the lid member 7 on the upper side of the container body 2, a portion located on the outer peripheral side of the frame rib 21 on the lower surface of the lid member 7. The container body 2 is supported in contact with the upper surface of the flange portion 4. Further, the outer peripheral surface of the frame rib 21 is in contact with or close to the inner peripheral surface of the accommodating portion 3, thereby preventing the positional displacement of the lid member 7 in the horizontal direction with respect to the container body 2.

  In the present embodiment, the outer peripheral dimension of the lid member 7 is configured to be smaller than the outer peripheral dimension of the flange portion 4. The lid member 7 has a substantially square shape whose corners are chamfered when viewed from above, and the flange portion 4 has a rectangular frame shape whose four sides are the same length and whose corners are chamfered when viewed from above. I am doing. Furthermore, each side part of the lid member 7 is shorter than each side part of the flange part 4 and longer than the inner diameter of the housing part 3 (distance between the side wall parts facing the housing part 3). For this reason, when the lid member 7 is attached to the container body 2, the outer peripheral edge of the lid member 7 is positioned on the inner peripheral side with respect to the outer peripheral edge of the flange portion 4 and on the outer peripheral side with respect to the inner peripheral edge of the flange portion 4. (Refer to FIG. 2, FIG. 6, etc.). Further, due to the presence of the frame rib 21, the relative positional relationship between the lid member 7 and the flange portion 4 as described above is maintained in a state where the lid member 7 is attached to the container body 2.

  Furthermore, the lid member 7 of the present embodiment is configured such that corner ribs 11, frame ribs 21, and the like protrude from the upper surface side and the lower surface side of the main body portion of the flat lid member 7. The upper and lower surfaces of the are flat surfaces. Moreover, the upper surface of the flange part 4 extended from the upper edge part whole region of the accommodating part 3 is a flat surface, Comprising: The height position is the same also in any site | part in the circumferential direction. For this reason, in a state where the lid member 7 is mounted on the container body 2, the lid member 7 and the flange portion 4 are continuously in contact with each other over the entire outer peripheral edge of the lid member 7.

  In this embodiment, when the container main body 2 is placed on the upper side of the lid member 7, the outer peripheral surface of the upper container main body 2 (accommodating portion 3) is a corner of the lower lid member 7 at each corner portion. The rib 11 is in contact with or close to the vertical wall portion 12. As a result, horizontal displacement between the lower lid member 7 and the upper container body 2 is prevented, and the lidded containers 1 can be suitably stacked as shown in FIG. Yes.

  As described above in detail, according to the present embodiment, the outer peripheral dimension of the lid member 7 is configured to be smaller than the outer peripheral dimension of the flange portion 4, and the lid member 7 is attached to the container body 2 in the mounted state. The outer peripheral edge of 7 is located on the inner peripheral side of the outer peripheral edge of the flange portion 4. With this configuration, it is possible to avoid a situation in which wind blowing from below the flange portion 4 hits the lower surface of the lid member 7 and the lid member 7 is lifted. Furthermore, for example, when the lid member 7 protrudes to the outer peripheral side from the outer peripheral edge of the flange portion 4, for transportation, etc., with respect to the portion that protrudes to the outer peripheral side from the flange portion 4, A predetermined object or the like (for example, when the containers with lids 1 are stored side by side in contact with each other, the lid member 7 of the container 1 with the lid installed next to each other) comes into contact with the lid member 7. The situation of pushing up can be suppressed. Accordingly, the lid member 7 may be lifted carelessly without providing an engaging means for engaging the lid member 7 and the container body 2 or a sealing means for sticking between the lid member 7 and the container body 2. The situation where it comes off can be suppressed. Further, compared to the case where the engaging means is provided, the manufacturing of the lidded container 1 is not complicated, and the convenience in opening and closing the lidded container 1 can be enhanced. Furthermore, compared with the case where the said sealing means is stuck, the opening / closing workability | operativity of the container 1 with a lid | cover can be improved, and the trace (adhesive agent) which peeled off the sealing means to the lid member 7 or the container main body 2 Etc.) and the risk of deterioration of appearance, touch, hygiene and the like can be avoided.

  In addition, for example, as in the case where the lid member 7 protrudes to the outer peripheral side of the outer peripheral edge of the flange portion 4, the lidded container 1 with the lid member 7 attached is put on the lower surface of the flange portion 4 with a finger. Therefore, it is possible to avoid a situation in which it is difficult to place a finger on the flange portion 4 due to a portion of the lid member 7 that protrudes from the outer peripheral side of the flange portion 4 when the cover member 7 is lifted by hand.

  Further, in the present embodiment, in a state where the lid member 7 is mounted on the container body 2, the lid member 7 and the flange portion 4 are continuously in contact with each other over the entire outer peripheral edge of the lid member 7. Therefore, the opening of the container body 2 can be completely closed, and a situation in which wind directly hits the lower surface of the lid member 7 over the entire lid member 7 can be avoided. The above-described effects such as suppression are more reliably exhibited.

  Since the corner ribs 11 are provided at the four corners of the upper surface of the lid member 7, the lidded containers 1 can be stably stacked, and the corner ribs 11 can be attached to and detached from the lid member 7 and carried. It can be used as a handle for the occasion. However, since the corner rib 11 is provided on the lid member 7, the lid member 7 is likely to be affected by a cross wind or the like, and the lid member 7 is likely to float or come off from the container body 2. . On the other hand, in this embodiment, the ventilation hole 15 is formed in the vertical wall part 12 of the corner rib 11. For this reason, the wind blown to the vertical wall part 12 can escape from the ventilation hole 15. Therefore, the wind pressure which the vertical wall part 12 receives can be reduced, and the said malfunction can be suppressed as a result.

  Further, the corner rib 11 is provided with a protruding portion 13 that extends from the upper edge portion of the vertical wall portion 12 to the outer peripheral side of the lid member 7, whereby the strength of the corner rib 11 can be increased and the protruding portion can be increased. Since the lid member 7 can be attached and detached by placing a finger on the portion 13, it is easier to open and close the lidded container 1. However, there is a concern that the wind blows on the lower surface of the overhanging portion 13 and the lid member 7 is likely to float or come off from the container body 2. On the other hand, according to the present embodiment, the upper surface ventilation hole 16 is formed in the overhanging portion 13, so that the wind blown to the overhanging portion 13 can be released from the upper surface ventilation hole 16. Therefore, the wind pressure which the overhang | projection part 13 receives can be reduced and the said malfunction can be suppressed as a result.

  In the configuration where the outer peripheral edge of the lid member 7 is located on the inner peripheral side with respect to the outer peripheral edge of the flange portion 4 as described above, it is difficult to place a finger on the outer peripheral edge of the lid member 7 when removing the lid member 7. Since the corner rib 11 can be used as a handle, it is possible to dramatically improve detachability and workability. Further, since the protruding portion 13 of the corner rib 11 protrudes from the upper edge portion of the vertical wall portion 12 to the outer peripheral side of the lid member 7, the outer peripheral side of the lid member 7 with respect to the protruding portion 13 when the lid member 7 is attached or detached. The finger can be hooked from the side, force can be easily applied, and the opening and closing workability of the lidded container 1 can be further facilitated.

  Further, since positioning ribs (corner ribs 11) for stably stacking the containers 1 with lids are provided corresponding to the four corners of the lid member 7, the four corners that are relatively easily deformed are provided. The rigidity can be increased and deformation can be suppressed. Further, since the weights of the four corners of the lid member 7 are increased, it is possible to suppress a situation in which the corners of the lid member 7 are lifted when the lid member 7 receives wind.

  Furthermore, the deformation of the lid member 7 is more reliably suppressed by providing the cross ribs 22 that connect the diagonal corner portions of the frame rib 21 on the lower surface side of the lid member 7. That is, not only the deformation at the time of molding is suppressed, but also sufficient strength to support the lidded container 1 placed on the upper side without deformation even when the lidded containers 1 are stacked. be able to. Therefore, the deformation of the lid member 7 is prevented, so that the upper surface of the flange portion 4 and the lower surface of the lid member 7 can be brought into contact with each other reliably. It is possible to prevent a situation where the main body 2 is easily floated or detached.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.

  (A) In the above embodiment, the container body 2 and the lid member 7 are made of polypropylene, but may be made of other resin materials such as polyethylene, PET, and polyamide. Also, with a lid provided with a container body in which a drain hole or a rib is formed in the bottom wall portion or the side wall portion of the accommodating portion 3, or an opening portion and a door member for closing the opening portion are provided in the side wall portion. It is also possible to apply the structure of the said embodiment to a container.

  (B) In the above embodiment, the connecting portion 14 may be formed with a ventilation hole penetrating in the circumferential direction of the lid member 7. Moreover, the vertical wall part 12 and the overhang | projection part 13 may be formed in a grid | lattice form etc., and the opening area of the ventilation holes 15 and 16 may be increased.

  (C) In the above embodiment, each side portion of the lid member 7 is configured to be substantially linear, but may be configured to be bent or bent at an intermediate position. Further, in the above embodiment, the positioning ribs (corner ribs 11) for stacking are provided corresponding to the four corners of the lid member 7, but are provided at intermediate positions on the side portions of the lid member 7. Alternatively, it may be provided over the entire circumference. However, when the cover member 7 is provided on the entire circumference, the lid member 7 is easily affected by the wind. When the cover member 7 is provided at an intermediate position, the weight at the corner of the cover member 7 is lightened and the corner is easily lifted. Therefore, it is desirable to provide at four corners as in the above embodiment.
