Description

  This invention collects and conveys waste or recycled resources such as combustible waste, empty cans, empty bottles, and waste wood, transports earth and sand in civil engineering work, transports various raw materials, materials and products inside and outside the factory, and fishery products The present invention relates to a foldable container that can be used for various purposes such as harvesting and transporting crops and can be folded.

Conventionally, containers are used for applications such as collection of waste or recycled resources. In consideration of convenience when not in use, the container is often a foldable folding container.
Although there are various variations in the configuration of the folding container, for example, the following is known in which the applicant of the present application has obtained Japanese Patent No. 2782500.
The folding container according to this application includes a bottom surface that is substantially square, and four side surfaces that are substantially square, each having a lower end connected to each of the four sides surrounding the bottom surface. It is a container configured in a box shape having an opening that is a combination of four sides and is surrounded by the upper sides of the four side surfaces.
The container is configured such that each side surface can be bent inward while being substantially along a diagonal line having the same positional relationship when each side surface is viewed from the front. In such a container, each of the four side surfaces is a side perpendicular to the bottom surface of two substantially right triangles formed by dividing each side surface by a diagonal line, including the intersection of the diagonal line and the upper edge. Is bent inward and folded in half, with the vertical side overlapping the adjacent base, which is the base of the side sharing the right-angled triangle, so that the opening is 90 ° to the bottom. It can be folded in a twisted state.

Such a folding container can be folded to the size of the bottom surface of the folding container, and its folding and assembling are easy, so that it is very useful.
However, since the folding container has to be pushed down toward the bottom surface while twisting the opening with respect to the bottom surface, folding requires some labor.

  This invention makes it the subject to improve the above folding containers so that it can fold more easily.

The folding container according to the present invention that solves the above-described problem has a bottom surface that is substantially square and four side surfaces that are substantially square in which the lower side is connected to each of the four sides surrounding the bottom surface. Are combined in a box shape having an opening substantially corresponding to the bottom surface surrounded by the upper edge of the four side surfaces, and each of the side surfaces is each of the side surfaces. 2 is made to be able to bend inward while substantially following a diagonal line having the same positional relationship when viewed from the front, and each of the side surfaces is formed by dividing the side surface by the diagonal line 2 An edge that is perpendicular to the bottom surface of an approximately right triangle that includes an intersection of the diagonal line and the upper edge, and an adjacent edge that is the base of the side that shares the perpendicular edge with the approximately right triangle. While so as to overlap the bottom, by two folded by bending inward, the opening, in which is the collapsible in a state of twisted 90 ° composed with respect to the bottom surface.
This folding container is provided with a linear body that is arranged along the opposite ends of a diagonal line that intersects the diagonal line on any two side faces that are at opposite positions of the four side faces. It can be folded by pulling outward.
In addition, as a linear body, a rope and cloth tapes can be used, for example.

In this folding container, when, for example, approximately the center of each of the two linear bodies is pulled to the outside of the folding container, both ends of the linear body are drawn, so that the upper ends of the linear bodies are fixed (or The apex (which is in the vicinity of the position where the upper end of the linear object is fixed) is drawn toward the apex where the lower end of the linear object is fixed (or in the vicinity of the position where the lower end of the linear object is fixed) Will be. Thus, the folding container is pushed down while twisting the opening 90 ° by simply pulling the linear body to the outside of the folding container, and overlapped on the bottom surface.
Therefore, this folding container is in a state of use (the folding container has a box-like shape) rather than the conventional folding container that required to push down the opening toward the bottom while twisting the opening with respect to the bottom. It will be easier to fold from the state.
The ends of the linear body are usually fixed to each of the two vertices that need to be brought close to each other when the linear body is pulled outward, or to the vicinity of each of the two vertices. More specifically, both ends of the linear body can be fixed to vertices located at both end portions of the diagonal line, for example, on the side surface including the diagonal line along which the linear body extends, or from the vertex to the inside of the side surface. It is possible to fix to a range that can be said to be a neighborhood from those vertices that are slightly closer to. The two ends of the linear body should be close to each other when the linear body is pulled outward, while the two vertices that need to be close to each other when the linear body is pulled outward. For example, it may be fixed on any side surrounding the side surface including the diagonal line along which the linear body extends, or may be fixed to the adjacent side surface or the bottom surface beyond the side. Absent.
In addition, the linear body may have some slackness in the state fixed to the side surface of the folding container in use, or may not have slackness.
Further, the fixing of the linear body to the side surface can be performed by sewing or bonding its end to the two apexes or in the vicinity thereof. Further, the fixing of the linear body to the side surface can be made detachable by using a velcro tape or a shackle.
It is sufficient that the linear body is provided on any two side surfaces at opposite positions of the four side surfaces, but may be provided on all four side surfaces.
Note that the bottom surface, the four side surfaces, and the opening of the folding container are all substantially square as described above. These may or may not be perfect squares. As long as the folding container can be substantially folded as described above, the bottom surface, the four side surfaces, and the opening of the folding container can be formed into a shape other than a perfect square such as a rectangle.

As described above, the side surface of the folding container in the present invention is a portion of the diagonal line that divides the side surface, and can be folded in two toward the inside. The side surface may be made of a hard material or a flexible material as long as the opening can be made to approach the bottom surface while twisting the opening with respect to the bottom surface.
In the former case, each side surface is divided into two substantially right-angled triangular members on a diagonal line, and is hinged or the like, for example, so that it can be bent at the diagonal line part.
In the latter case, each side surface can be freely bent at any part, so that it can naturally be bent along a diagonal line. In the latter case, the four side surfaces are formed of a flexible film material, and the side adjacent to the side surface adjacent to the side surface is associated with one of the four corners of the bottom surface. Four support members that extend vertically above any of the four corners of the bottom surface, are harder than the side surfaces, and are independent of the side surfaces, and the four support members are attached to the adjacent bottom sides. It can be made to be piled up.
As the flexible film material, a woven fabric, a woven fabric coated with resin or rubber, or the like can be used. The film material may be composed of a plurality of materials. The woven fabric may be transparent, translucent, mesh-shaped, etc., so that the inside of the folding container can be seen.

The support material is useful for supporting the membrane material, and the specific configuration thereof is not limited as long as it is overlapped with the adjacent bottom side. For example, the support material can be a rod-shaped or plate-shaped member. When it is a plate-shaped member, the shape of the planar part does not ask | require a support material. For example, the shape of the planar portion of the support material can be an elongated rectangle. The length of the support member in the vertical direction can be made substantially the same as the length of the side where the adjacent side surfaces are adjacent to each other, but may be shorter than that. As the material of the support material, for example, a material having a certain degree of rigidity such as resin, FRP, rubber, metal, and wood can be used. The support material may or may not be connected to the bottom surface. In the latter case, the support material is fixed to, for example, a film material constituting the side surface.
The fixing to the side surface of the support material may be performed in any way. For example, adhesion and welding can be used for the fixing. Moreover, the bag which can insert a plate-shaped support material, for example in the said side surface is provided, and a support material can also be attached to a side surface by inserting in the bag.
The support material may straddle adjacent side surfaces. If the above-described bag is used, the bag may straddle adjacent side surfaces. In addition, when the support material or a bag is made to straddle the adjacent side surface, the case where the support material or the bag is connected to both adjacent sides of the adjacent side surface is also included.
The support material may be provided on one of the adjacent side surfaces so as not to straddle the adjacent side surfaces. In this case, the support member may be provided so as to be along the side adjacent to the adjacent side surface among the sides of the side surface. For example, the support member is plate-shaped, and is provided on the side surface so that the planar portion thereof faces the adjacent bottom side and along the side adjacent to the side surface adjacent to the side surface. Also good. When such a support material is used, there are the following advantages. That is, when considering the case where the lower end of the plate-like support material is in contact with the bottom surface, it is easy to tilt in the thickness direction, but it is difficult to tilt in the width direction. Therefore, if the plate-like support material is provided so that the surface-shaped portion faces the adjacent bottom side of the side surface adjacent to the side surface on which the support material is provided, the direction in which the support material falls can be regulated so as to go to the adjacent bottom side. Thereby, it becomes easy to fold a folding container, rotating the opening 90 degrees toward a bottom face.

An opening support member that keeps the shape of the opening harder than the side surface along the upper end portion of the side surface may be provided. It is not always necessary to provide the opening support material on all the side surfaces.
By providing the opening support member, the flexibility of the film material around the opening is reduced, and the opening state can be stably maintained.

  Furthermore, a handle formed by fixing both ends of the string to the side surface in the vicinity of the upper end of any two side surfaces at opposite positions of the four side surfaces, the length direction of the handle is You may attach so that the edge of the upper end of the side surface attached may be followed. The handle may be provided near the upper ends of all the side surfaces.

When this handle is used, the folding container can be easily made into a shape in use by simply pulling the handle to the outside of the folding container.
The string in this case may be a rope having a circular cross section or an elliptical cross section, or may be a tape having a rectangular cross section.

  Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings.

A bag with a bottom. The fixed bag 6x in this embodiment is provided so as to be positioned at the left end when the side surfaces 3a to 3d are viewed from the front. In this embodiment, the fixed bag 6x is made of the same film material used when the side surfaces 3a to 3d are formed. In other words, in the portion where the fixed bag 6x is present, the film material constituting the side surfaces 3a to 3d is doubled. The support member 6 is fixed to each of the side surfaces 3a to 3d by being inserted into the fixed bag 6x. In addition, the above-described oblique side at the upper end portion of the support member 6 in this state protrudes from the upper end of the fixed bag 6x.
In this way, each of the support members 6 fixed to the side surfaces 3a to 3d includes a support member 6 provided on the side surface 3a, a support member 6 provided on the side surface 3b, and a support member 6 provided on the side surface 3b. The support material 6 provided on the side surface 3c on the bottom side 2c of 3c is superposed on the bottom side 2d of the side surface 3d, and the support material 6 provided on the side surface 3d is superimposed on the bottom side 2a of the side surface 3a. .

In addition, the support material 6 can be made into rod-shaped members, such as circular, an ellipse, and a polygon, for example. In this case, the cross-sectional shape of the fixed bag 6 x can correspond to the cross-sectional shape of the support material 6.
In addition to the attachment position shown in FIG. 2A, the fixed bag 6x can be attached to the attachment position shown in FIG. 2B or the attachment position shown in FIG. The fixed bag 6x shown in FIG. 2B straddles adjacent ones of the side surfaces 3a, 3b, 3c, and 3d, and the fixed bag 6x shown in FIG. Adjacent ones of 3b, 3c and 3d are connected to each other. 2 (b) and 2 (c) has a different cross-sectional shape from that shown in FIG. 2 (a), and a support member 6 having a circular cross section is inserted. The cross-sectional shape is convenient for the above.
An opening support member 7 is attached to the upper end portions of the side surfaces 3a, 3b, 3c, and 3d. In this embodiment, the opening support member 7 is not necessarily required to be formed, but is formed of the same resin as the support member 6, has a plate shape, and has the same width as the support member 6. Further, the portion of the opening support member 7 that is close to the support member 6 is cut so that the oblique side of the support member 6 corresponds to the oblique side and the tip angle of the part is 45 °.
The opening support member 7 may be attached to the side surfaces 3a to 3d in any manner, but in this embodiment, the opening support member 7 is attached to the side surfaces 3a to 3d using the opening fixing bag 7x. Has been made. The opening fixed bag 7x is simply a fixed bag 6x arranged in the lateral direction. In this embodiment, as shown in FIG. 3, the opening fixing bag 7x has a shape corresponding to the shape of the opening support member 7. . In FIG. 3, the portion where the open fixed bag 7 x exists and the portion where the fixed bag 6 x exists are shown by shading. By being inserted into the opening fixing bag 7x, the opening support member 7 is attached to the side surfaces 3a to 3d.
More specifically, the upper side of the side surface 3b and the side surface 3d at the opposite positions of the side surfaces 3a to 3d is formed of a flexible tape material on the outside of the opening fixing bag 7x in which the opening support material 7 is inserted. A handle 8 is attached. The handle 8 is attached so that its length direction is along the length direction of the opening support 7. The handle 8 is attached so that both ends of the planar portion face the opening support member 7. The handle 8 may be provided on the side surfaces 3a and 3c in addition to the side surfaces 3b and 3d. Further, in this embodiment, the opening support member 7 on the side surface 3a is provided with a fixing member 7c, which is a velcro tape, which is detachably fixed to the fixing member 5c described above.

The two opposite side surfaces 3b and 3d of the side surface 3 have one end corresponding to the lower end of the support member 6 and the other end corresponding to the end portion of the opening support member 7 far from the support member 6. A linear body 9 is provided, which is fixed to each part. The linear body 9 is provided so as to be along the diagonal line of the side surfaces 3b and 3d and to have the same positional relationship when the side surfaces 3b and 3d are viewed from the front.
In this embodiment, both ends of the linear body 9 are fixed to the above-described portions of the side surfaces 3b and 3d. From the apex close to the lower end of the support member 6 and the support member 6 of the opening support member 7 It is not exactly fixed to the apex near the far end. Both ends of the linear body 9 in this embodiment are fixed to portions slightly closer to the centers of the side surfaces 3b and 3d from the two vertices described above. But the both ends of the linear body 9 may be fixed to the above-mentioned two vertices. Alternatively, both ends of the linear body 9 are fixed to predetermined sides of the side surfaces 3b and 3d, or to the other side surfaces 3a and 3c other than the side surfaces 3b and 3d, or the bottom surface 1 as long as they are in the vicinity of the two vertices. May be.
In this embodiment, the linear body 9 is not limited to this, but is formed of a flexible cloth tape-shaped member, but may be formed of a rope.
Although both ends of the linear body 9 can be detachably attached to the side surfaces 3b and 3d, in this embodiment, they are fixed to the side surfaces 3b and 3d.
The linear body 9 may be provided on the side surfaces 3a and 3c in addition to the side surfaces 3b and 3d.

Next, the usage method of this folding container is demonstrated.
The folding container in use is in the state shown in FIG. A desired item such as a waste can be placed inside the folding container.
The lid 5 is placed over the opening 4 as necessary. When the lid 5 is put on the opening 4, the fixing member 5c and the fixing member 7c can be fixed. When the lid 5 is opened, the handle 5d may be pulled.

When folding a folding container, such as when not using a folding container, the linear body 9 should be kept away from the side surfaces 3b and 3d to which it is attached with the lid 5 closed. Just pull. With that alone, the folding container is folded.
The manner in which the folding container is folded will be described with reference to FIG.
When the substantially central portion of the linear body 9 attached to the side surfaces 3b and 3d is pulled toward the outside of the folding container, both ends of the linear body 9 approach each other. That is, on the side surfaces 3 b and 3 d, the end of the opening support member 7 on the side far from the support member 6 approaches the lower end of the support member 6.
In the side surface 3b, when the end of the opening support member 7 far from the support member 6 approaches the lower end of the support member 6, the support member 6 provided on the side surface 3a falls down and overlaps the bottom side 2b of the side surface 3b. . In the side surface 3d, when the end of the opening support member 7 far from the support member 6 approaches the lower end of the support member 6, the support member 6 provided on the side surface 3c falls down and overlaps the bottom side 2d of the side surface 3d. . At the same time, the support material 6 provided on the side surface 3b overlaps the bottom side 2c of the side surface 3c, and the support material 6 provided on the side surface 3d overlaps the bottom side 2a of the side surface 3a.
Moreover, when each support material 6 falls down, each side surface 3a-3d formed with the flexible raw material will be automatically folded into two. The side surfaces 3b and 3d are folded in two along a diagonal line intersecting with the diagonal line on which the linear body 9 is stretched. Further, the side surfaces 3a and 3c are folded in two so that the folds when viewed from the front are the same as the folds on the side surfaces 3b and 3d. When the side surfaces 3a to 3d are folded in two, the folds of the side surfaces 3a to 3d coincide with the gaps located between the above-described inclined surface of the support member 6 and the above-described inclined surface of the opening support member 7, The support member 6 and the opening support member 7 do not get in the way when the side surfaces 3a to 3d are folded in half.
Thereby, from the state of FIG. 1 (assuming that the lid 5 is closed), the folding container is brought into the state of FIG. 4B through the state of FIG. 4A. The state of FIG.4 (b) has shown the state by which the folding container was folded completely and became flat form.
At this time, the opening 4 of the folding container is twisted clockwise by 90 ° with respect to the bottom surface in a plan view.

When returning the folding container to the use state, the two handles 8 are grasped at the same time, and they are pulled in opposite directions.
By doing so, the folding container follows the process opposite to the above-described process of folding the folding container, and rises perpendicularly to the bottom surface while being twisted back by 90 ° in the opposite direction to the folding time. The shape shown in FIG.
