Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to containers, and in particular, containers that have an open top surface, can be stacked on top of each other, and that have a side wall of the container body that allows objects to be stored inside the container body. It relates to a type of container with an opening that can be opened and closed for loading and unloading.

[Background of the idea]

Conventionally, in this type of container, an opening/closing side plate is pivotally attached to the middle part of the side wall of the container body, and when the side wall of the container body is opened, the opening/closing side plate is rotated downward to the outside of the container.
A container has been proposed in which an opening/closing side plate is rotated upward of the container when the side wall of the container body is closed. (Utility Model Publication No. 47-24260) In such a container, it is practically difficult to make the height of the opening provided in the side wall of the container more than half of one side wall of the container body. It is not possible to enlarge the opening for taking things in and out.

[Purpose of invention]

The object of the present invention is to provide a container which has an opening at the top, which allows containers to be stacked together, and which has an opening in the side wall of the container body for taking in and taking out stored items, the opening being sufficiently large. Our goal is to provide containers that can.

[Summary of the idea]

In the present invention, an opening/closing side plate, that is, a flap is rotatably held at a portion of the container body located near the ridge between the side wall having the opening and the bottom, and the flap closes the opening, and the flap closes the opening. When opening the flap, the flap is stored in a storage section provided on the bottom back side of the container body,
A container having a container body having an open top surface and an opening formed in a side wall so that they can be stacked on top of each other, and a flap held on the container body so that the opening can be freely opened and closed. is provided with a pair of hanging bodies extending downward from the bottom part and spaced apart from each other by approximately the same width as the width of the flap, and the flap has a lower end portion when the opening is closed. The flap is located near the ridge between the side wall having the opening of the container body and the bottom of the container body, and the flap is closed with the opening at both end portions of the lower end portion of the flap. A holding structure is provided that rotatably holds the flap so that it cannot fall off, and a pair of hanging bodies extend from the holding structure portion of the flap to a portion corresponding to both end portions of the portion that becomes the lower end portion in the state. This is a container equipped with guide rails to guide the direction of travel.

[Example of idea]

1 to 3 show a first embodiment of the present invention,
In the container in this embodiment, a pair of hanging handles 13 are pivotally supported on the periphery of the opening for hanging the container with one hand.
When each of the pair of hanging handles is tilted outward from the suspended state, the entire hanging handle is placed on the periphery of the opening, and input-type empty stacking (nesting) of containers can be achieved. When each of the containers is tilted inward, the hanging handles intersect and are positioned above the opening on the top surface of the container, and the bottom of the upper container is placed on the hanging handle of the lower container, resulting in stacking of containers (stacking). The container has an opening 1 on one side wall 4 of the container body for taking in and taking out stored items, and a large diameter part on the distal end side and a small diameter part on the proximal side on the upper side wall of the opening 1. Three bosses 2 are formed at predetermined intervals. Ribs 3 extend below the bottom from two side walls perpendicular to the side wall 4 having the opening 1 of the container body, and a pendant body 5 is positioned slightly inside the ribs 3 and extends downward from the bottom. It has been extended to This hanging body 5 has a notch 1 approximately in the center on the lower end side.
4, and a stopper 6 is formed on the inner surface of the end on the side closer to the opening 1.

A vertically long hole 7 is formed in the hanging body 5, and a guide hole (groove) 8 is provided as a guide rail communicating with the vertically long hole 7 and parallel to the bottom surface of the container body. Three vertically elongated holes 10 having a larger diameter on the lower side are formed on the upper side of the flap 9 at positions corresponding to the three bosses 2, and a finger hook 11 is formed along the upper edge of the flap 9. There is. The lower edge of the flap 9 is bent, and a boss 12 is attached to each end.

In the first embodiment, when the opening 1 is closed, the boss 12 is inserted into the vertical hole 7 as shown in FIG.
The boss 2 is locked in the vertical hole 10 of the flap 9.
It is locked inside. To open the opening 1, place your finger on the finger hook 11 and lift the flap 9 upward to position the large diameter part of the lower end of the vertical hole 10 on the boss 2, and then place the finger hook 11 on the side wall of the container body. By pulling outward from the flap 9, the flap 9 is released from the restraint by the boss 2.

Next, place your hand on the finger hook 11 and move the boss 12 along the guide hole 8 while rotating the flap 9 downward using the boss 12 as a fulcrum, and move the flap 9 into the area held by the hanging body 5. Push it in.
When the boss 12 reaches the inner end of the guide hole 8,
When you release your hand from the finger hook 11, the flap 9 will close to the stopper 6, as shown by the two-dot chain line in FIG. placed on top. When closing the opening 1, perform the operation opposite to the operation when opening it.

In the stacked state of containers as shown in FIG. 3, the cutout portion 14 of the container on the upper stage is placed on the hanging handle 13 on the lower stage. In this case as well, the operations for opening and closing the opening of the upper container are the same as described above. However, the position of the flap 9 when the opening is opened is such that the flap 9 is in contact with the upper end surface of the side wall of the container main body on the lower stage side, as shown by the two-dot chain line in FIG.

4 to 7 show a second embodiment of the present invention.
In the figure, an opening 21 is formed on one side wall 24 of the container body.
is provided, and two engagement holes 22 are formed at intervals in the side wall above the opening 21.
A rib 23 extends downward from the bottom from two side walls perpendicular to the side wall 24 having the opening 21 of the container body, and a pendant body 25 extends downward from the bottom, located slightly inside the rib 23. It has been extended. A rail 26 is provided on the inner surface of each of these hanging bodies 25 so as to be parallel to the bottom of the container body.
is installed. Further, a stopper 27 is provided on the inner surface of the end of the hanging body 25 on the side closer to the opening 21, located above the rail 26.

The flap 28 has a thin hinge portion 29 and a push-down piece 30 formed along its upper edge, and an engagement piece 32 having an engagement claw 31 at its tip extends from the push-down piece 30. The lower edge of the flap 28 is bent, and approximately fan-shaped ribs 33 are provided at a predetermined interval from both ends of the flap 28, and bosses 3 are formed from these ribs 33 toward the outside of the container.
4 is installed. Other than the flap opening/closing mechanism, this container is substantially the same as the container shown in the first embodiment.

In the second embodiment, when the opening 21 is closed, the engaging pawl 31 of the flap 28 engages the engaging hole 21.
2, the boss 34 is locked to the stopper 27, and the lower end of the flap 28 is placed on the rail 26. When opening the opening 21, by pushing down the push-down piece 30, the engagement pawl 31 is unlatched from the engagement hole 22 via the thin-walled hinge portion 29, and the push-down piece 30 is moved toward the outside of the container body. Pull back to release the restraint of the flap 28 by the engagement hole 22.

Next, place a finger on the push-down piece and move the lower end of the flap 28 along the rail 26 while rotating the flap 28 downward using the boss 34 as a fulcrum.
A flap 28 in the area sandwiched by the depending body 25
to store. In this case, the flap 28 does not come into contact with the floor surface, as shown by the two-dot chain line in the figure. To change the opening 21 from the open state to the closed state, perform almost the opposite operation to the above. After pulling out the flap 28 in the horizontal direction, raise it up and operate the push-down piece 30 to release the engaging claw 31. What is necessary is just to make it lock in the engagement hole 22.

Figures 8 to 10 show a third embodiment of the present invention, and the opening/closing mechanism of the side wall opening of the container main body by the flap is substantially the same as that of the first embodiment, and therefore corresponds to this opening/closing mechanism. The members used in this embodiment are designated by the same reference numerals as those in the first embodiment. In this embodiment, the container serves as both a stacking type and a nesting type.

That is, support parts 35 projecting upward are provided on both side edges of the upper part of the container main body, and a hanging handle 36 is rotatably provided on these support parts 35. In this container, the hanging handle 36 is in a hanging state as shown by A in the figure during nesting,
When stacking, the container is rotated upward and inward and positioned above the opening on the top surface of the container.

In each of the first to third embodiments, the flap is in close contact with the side wall of the container body, except for the upper end, and has no outwardly projecting portion. Therefore, the empty stacking ratio during nesting (where A is the height of the container and B is the height of the part of the upper container that is stored in the lower container, is expressed as B/A). ) can be increased. Incidentally, in the container described in Utility Model Publication No. 47-24260, the empty loading ratio during nesting is only about 1/2.

11 to 13 show a fourth embodiment of the present invention, in which the container has stacking ribs extending outwardly on the side wall near the bottom to form stacking ribs on the side walls of the upper container. A container that can achieve stacking of containers by placing a stacking rib on the opening periphery of the lower container, and in this embodiment, has an opening 41 on one side wall of the container body,
This embodiment is the same as the first embodiment in that a boss 42 is provided on the side wall above the opening 41, and a vertically elongated hole 44 having a larger diameter on the lower side is provided in the upper part of the flap 43. In this embodiment, a protruding piece 45 is provided vertically protruding along the side wall of the container body, and a vertically elongated hole 46 is formed in the lower part of this protruding piece 45, communicating with the elongated hole 46 and connecting to the hanging body 48. A guide hole 49 is formed. Furthermore, bosses 47 are formed at both ends of the lower end of the flap 43.

Therefore, the opening and closing operations of the opening 1 in this embodiment are similar to those in the first embodiment.

As mentioned above, this invention is a stacking type,
Applicable to any nesting type container.

[Effect of idea]

According to the present invention, most of one side wall of the container body can be made into an opening, and even if the opening is made large, there is no problem in opening and closing the opening during stacking. In this case, the empty stacking ratio can be increased by bringing the flap closer to the side wall surface and reducing the protrusion.
