Description

U-turn box {U-TURN BOX}

The present disclosure relates to a U-turn box for use for item recovery.

Typically, a box is used to store or transport items. The box is formed in a rectangular rectangular parallelepiped shape and has a loading space for accommodating an item therein, and a cover or an opening and closing device for opening and closing the box may be provided on the outside. Accordingly, it is possible to conveniently move the article by using the box, and the articles contained therein can be safely stored.

U-turn boxes are, for example, boxes used to retrieve returned items and should be easy to move, load and store. Conventionally, commonly used boxes are not suitable for use as U-turn boxes.

In the case of a paper box, it is disposable and can be conveniently used, but it takes up a lot of space when stored, and it is inconvenient to use because it must be opened and folded in a box shape. In addition, there is a disadvantage that the cover of the paper box must be sealed with a separate adhesive tape, and it is difficult to store for a long time because it is weak in moisture. In the case of a box made of natural material, it is resistant to moisture, but it is inconvenient to use because it is difficult to maintain its shape.

In the case of plastic boxes, they are sturdy and can be used over and over again, which is economical. However, this also takes up a lot of space when stored, and must be used by unfolding and folding in a box shape, and it takes a lot of packaging time and is inconvenient to use because it must be sealed with an adhesive tape. And, since the size is determined, it is difficult to reduce the volume, and there is a disadvantage of taking up a lot of space during transportation or storage. In addition, when the temperature is low, such as in winter, plastics are easily damaged, and safety accidents may occur.

As described above, conventional boxes have a simple structure with an internal space, and are difficult to use as U-turn boxes that require frequent movement and storage for product recovery. Accordingly, there is an urgent need to develop a U-turn box that can be used more effectively.

This task is to provide a U-turn box that is easy to store when not in use and minimizes the volume when folded, thus minimizing the space occupied during storage.

This task is to provide a U-turn box that is capable of stably maintaining its shape and varying its size according to the volume of the item loaded inside.

This task is to provide a U-turn box that is convenient to use and easy to carry.

The U-turn box of this embodiment includes a bottom member forming a bottom surface, side members connected to both side ends of the bottom member to form a side surface, an upper member connected to the top of the side member to form an upper surface, the bottom member and both side members, and It may include a rear member and a front member respectively connected to both ends of the upper member to form a rear surface and a front surface.

It is installed on at least one of the bottom member, the side member, the upper member, the rear member and the front member may further include an opening for opening and closing the inside of the box.

The opening and closing opening may have a structure for opening and closing the front of the box, including a zipper or Velcro tape that is installed along the edge of the box to which the front member is connected to the front member.

The box may be formed of a flexible fabric material.

The bottom member may have a structure in which a plate having a relatively higher rigidity than a sheet is inserted between two sheets.

The upper member may have a structure in which a plate having a higher rigidity than a sheet is inserted between the two sheets.

It is installed on at least one side of the box may further include a label attaching portion for displaying the contents of the box to the outside.

It may further include a handle for carrying the box.

The handle portion is attached to the bottom member spaced apart from each other and extends to the side member to form a handle, a pair of side rings installed on the side member in accordance with the interval of the strap, and supported to be movable through the strap It may include.

The handle portion may further include a corner ring installed at a bottom edge of the box and supported to be movable through the strap.

As described above, according to the present embodiment, it can be simply folded in a sheet form, and when used, it is formed in a box shape, so that it can be used conveniently.

You can freely change the size or shape of the box from sheet form to container form, and optimize the form of the box according to the items to be loaded.

By minimizing the volume when folded, it is easy to move and store, and the space required for storage can be minimized, and the weight of the box itself is light, so it is easy to use.

The size of the box can be appropriately adjusted according to the size of the items loaded inside, so that only the required size can be used, and a single box can contain items of various sizes.

By maintaining a box shape of an appropriate size regardless of the items to be loaded, it is possible to stack and unload the boxes neatly and neatly when loading a vehicle, and it is possible to stack and store a large number of boxes in an orderly manner without being disturbed even during storage.

Since the box can be simply closed with a zipper, it is easy to use and shortens the packaging time.

With a handle that can safely support and support the box, the box can be transported more safely and conveniently regardless of the volume or weight of the box.

It is possible to load and transport items with a minimum weight of 20 times or more.

Accordingly, frequent movement and transport are required, and can be effectively used as a U-turn box to load and store a large quantity.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. However, the following examples are only preferred examples of the present invention, and the present invention is not limited to the following examples.

1 and 2 show the structure of a U-turn box according to this embodiment.

In this embodiment, the box 100 may be formed in a rectangular parallelepiped structure.

In the following description, with respect to each side of the box 100 forming a rectangular parallelepiped, both sides in the x-axis direction in FIG. 1 are referred to as sides, both sides in the y-axis direction are referred to as front and back sides, and both sides in the z-axis direction are referred to as top and bottom surfaces. It is called this.

As shown, the box 100 of the present embodiment is connected to both side ends of the bottom member 10 and the bottom member 10 to form the bottom side, respectively, to form the side member 12, the top of the side member 12 The upper member 14, the bottom member 10 and both side members 12 and the upper member 14 are connected to form the upper surface, respectively, connected to both ends of the rear member 16 and the front member ( 18) may be included. Hereinafter, the member may refer to the entire bottom member 10, the side member 12, the upper member 14, the rear member 16, and the front member 18 constituting each side of the box 100.

The inner space formed by each member constitutes a loading space inside the box 100. The size of each member constituting the six sides of the box 100 or the size of the overall box 100 may be variously modified.

Each member constituting the box 100 may be formed of a flexible cloth material. Accordingly, the box 100 may be freely and flexibly folded or unfolded to change its volume. Therefore, when necessary, the volume of the box 100 can be minimized by folding each member, and in use, the volume can be expanded while each member is unfolded according to the items loaded inside the box 100.

Alternatively, each member may be made of a cloth whose surface is waterproof coated with PVC or the like. Accordingly, it is possible to prevent damage from external moisture or rainwater, or from getting the internal storage material wet, and clean the surface by cleaning the surface with a mop or the like.

The box 100 of this embodiment may have a structure that opens and closes the box 100 by selectively opening the front member 18. To this end, the front member 18 may be provided with an opening 20 for opening and closing the box 100.

As shown in Figure 1, in this embodiment, the opening 20 may be made of a zipper. The zipper (zipper) is to be able to open and close two strings with teeth that mesh with each other by pushing and pulling with a metal ring, and since this is already known, a detailed description will be omitted below.

In this way, by installing the zipper on the front member 18, it is possible to open and close the front of the box 100 more easily by opening and closing the zipper.

The zipper may be installed along the front end of the front member 18 and the edge of the box 100 to which the front member 18 is connected, that is, along the ends of both side members 12 and the upper member 14. The front member 18 is connected to and fixed to the bottom member 10, and a zipper may be installed at the other tip. Accordingly, when the zipper is operated, the front member 18 is fixed to the bottom member 10 and the remaining tip is opened to open and close the inside of the box 100.

In the box 100 of this embodiment, the front of the box 100 is opened and closed through the front member 18, so that the product can be more easily loaded or taken out of the box 100.

In addition to the zipper, the opening 20 may be formed of, for example, a Velcro tape. Velcro tape is a structure that is attached to each other by having a protruding surface and a ring surface, and since this is already known, a detailed description thereof will be omitted.

In addition, at one side of the side member 12 of the box 100, a label attachment part 30 for displaying the contents of the box 100 may be installed. The label attaching part 30 may have a transparent window structure in which a label can be inserted, for example. The label attachment part 30 is applicable to any structural surface capable of attaching and fixing the label to the side member 12. In addition to the above structure, the label attaching portion may include an identification tag that is fixed by being tied to a strap with a string or the like and inserting a tag inside. Accordingly, the identification tag attached to the strap can be easily displayed on the outside by inserting a tag for the item.

Since the label is displayed on the side of the box 100 by the label attachment part 30, it is possible to more easily check the items loaded inside the box 100.

As shown in FIG. 3, in the box 100 of this embodiment, a plate 40 may be inserted into the bottom member 10 to increase the rigidity of the bottom member 10.

To this end, the bottom member 10 may be formed in two layers, and a plate 40 may be inserted therein. The plate 40 is a thin flat plate structure, and may be formed of a material having a relatively higher rigidity than that of a sheet. The plate 40 is formed to have a size corresponding to that of the bottom member 10 and may be inserted into the bottom member 10. The plate 40 may be formed of, for example, a plastic material. Accordingly, the bottom member 10 of the box 100 has rigidity secured by the plate 40 so that the article loaded inside the box 100 can be supported more stably and the bottom surface of the box 100 is Stays more stable.

In this embodiment, the upper member 14 may also be inserted into the plate 40 to increase the rigidity. The upper member 14 may be formed in two layers and a plate 40 may be inserted therein. The plate 40 is a thin flat plate structure and may be formed in the same structure as the plate 40 installed on the bottom member 10. As the plate 40 made of a material having a relatively higher rigidity than the sheet is inserted into the upper member 14, the rigidity of the upper member 14 can be increased. Accordingly, rigidity with respect to the upper surface of the box 100 is also secured, so that the article loaded inside the box 100 can be supported more stably.

In this way, by the plate 40 installed on the upper member 14 together with the bottom member 10 of the box 100, the planar shape of the box 100 on the upper and lower surfaces can be maintained as it is. Accordingly, the box 100 maintains a rectangular parallelepiped shape regardless of the volume of the article loaded inside the box 100.

In addition, even if another box 100 is stacked on the box 100, the upper member 14 firmly supports it, so that a plurality of boxes 100 can be stably stacked to be transported and stored without collapse or disturbance.

Thus, despite the lightweight and flexible structure, a large number of boxes can be stacked and stored stably, and they can be neatly loaded in a vehicle to be transported and unloaded.

This embodiment may further include a handle part 50 for carrying the box 100.

Handles 50 are installed on both side members 12 of the box 100 to form a pair. The handle portion 50 installed on both side members 12 will be described below as an example of the handle portion 50 installed on one side member 12 with the same structure. The handle part 50 installed on the other side member 12 is replaced with this.

The handle part 50 is attached to the bottom member 10 by being spaced apart from each other and extends to the side member 12 so as to be installed on the side member 12 according to the distance between the strap 52 and the strap 52 forming the handle. And, the strap 52 may include a pair of side rings 54 that are supported movably through penetration.

The strap 52 is a string structure made of a flexible material that is elongated, and the middle portion is bent to form a handle, and both ends thereof extend toward the bottom member 10 and may be fixed to the bottom member 10. In FIG. 2, reference numeral 53 denotes a fixed portion of the strap 52 to the floor member 10. The strap 52 may be sewn to the bottom member 10 at a fixed portion or may be attached and fixed as a separate member.

The straps 52 installed on both side members 12 may be sufficiently extended to the center of the bottom member 10 and fixed to the bottom member 10 together. Alternatively, one long strap 52 may extend to both side members 12 to form two handle portions 50 integrally connected. The distance between the two ends of the strap 52 constituting the handle may be variously modified according to the size of the box 100.

The strap 52 extends to the center of the bottom member 10 to support the entire bottom member, so that the weight of the items that can be loaded in the box 100 can be significantly increased. That is, since the bottom member 10 of the box 100 is supported by the strap 52, the articles loaded inside the box are supported not only by the bottom member, but also supported by the strap across the bottom member. Accordingly, even if it is loaded in a box of a heavy article, it is possible to lift the box using a strap while preventing the bottom member from being torn or damaged.

Thus, in the case of the present embodiment, even though the weight of the box is less than 1 kg, it is possible to load and transport a high weight article that is about 20 times (20 kg) or more of the relative weight.

In this embodiment, the strap 52 may have a structure that is fixedly installed only on the bottom member 10 and separated from the side member 12 to move freely. And, the side member 12 is provided with a side ring 54 so as to support the strap 52 with respect to the side member 12. The side ring 54 has a strip shape and is arranged in a direction perpendicular to the strap 52, and both ends are fixed to the side member 12 so that the strap 52 can penetrate therebetween. The side ring 54 may have a structure that can be elastically stretched. For example, the side ring 54 may be formed of an elastic cloth woven like a rubber strap. Accordingly, when the handle is pulled and an external force is applied to the side ring 54, the side ring 54 is elastically stretched to minimize tearing or damage. The material, shape, or size of the side ring 54 may be variously modified.

The two side rings 54 are spaced apart at intervals corresponding to the spacing distance between both ends of the strap 52 and are fixedly installed on the side member 12. The strap 52 passes through the side ring 54 and is supported on the side member 12. Accordingly, the strap 52 is stably positioned on the side member 12 while the gap is maintained while passing through the side ring 54.

Accordingly, it is possible to stably lift and move the box 100 by using the strap 52 as a handle. And, regardless of the strap 52, the side member 12 can be freely deformed, so that the size of the box 100 is appropriately adjusted according to the volume of the article loaded inside the box 100. That is, the side member 12 of the box 100 is coupled with the strap 52 through the side ring 54, and the side ring 54 can be freely moved up and down along the strap 52. Accordingly, the side member 12 can be deformed while being folded or unfolded by freely moving up and down with respect to the strap 52. In this way, even if the user lifts the box 100 by holding the strap 52, the side member 12 is freely deformed and folded or unfolded, so that the size of the box 100 is appropriately deformed according to the volume of the internal storage article.

In addition, the handle portion 50 may further include a corner ring 56 installed at the bottom edge of the box 100 and supported by the strap 52 passing therethrough.

The corner ring 56 may have the same structure as the side ring 54. Two corner rings 56 may be installed at the corners between the bottom member 10 and the side member 12 by being spaced apart at intervals corresponding to the separation distance between the two ends of the strap 52, respectively.

The strap 52 is installed through the corner ring 56 and is supported on the corner ring 56. Accordingly, the strap 52 is supported by the corner ring 56 while passing through the corner between the bottom member 10 and the side member 12 to maintain the position more stably.

4 and 5 show the state of use of the box 100 according to the present embodiment.

When the box 100 is not used and stored, the box 100 may be folded flat and stored in a state in which the volume or size is minimized.

As shown in FIG. 4, the top member 14 and the bottom member 10 of the box 100 are maintained in shape by the plate 40. Except for the bottom member 10 and the upper member 14 of the box 100, all other parts are made of a flexible cloth material, so that they can be flexibly deformed and folded.

Thus, when the bag is placed on the ground without the contents inside the box 100, the side member 12, the front member 18, and the rear member 16 are deformed by their own weight, so that they are folded inward and pressed flat. do. Therefore, it is possible to minimize the volume of the box 100 to be stored.

When the box 100 is used in this state, the size of the box 100 is varied according to the volume of the article accommodated in the box 100.

In one embodiment, a box having a length of 70 cm, a width of 40 cm and a height of 50 cm may be transformed to be stored and moved in the form of a flat sheet of 70 cm, width 40 cm, and height 1.5 cm. Accordingly, the box of this embodiment can be used by deforming about 35 times or more in volume. In the case of a conventional plastic box, 35 boxes of the above standard can be loaded in a 1 ton truck. On the other hand, in the case of the present embodiment, the volume of the box is appropriately varied according to the items contained therein, so that 48 or more can be loaded in a one-ton truck.

In a state in which the article is loaded inside the box, the operator can easily lift and move the box 100 using the strap 52.

As shown in Fig. 5, the box 100 maintains its shape by the bottom member 10 and the plate 40 installed inside the upper member 14, and stably stores the items P loaded therein. Can be supported by The side member 12 is deformable in size according to the volume of the article P accommodated in the box 100 in a freely deformable state. When the article P is loaded in the box 100, the side member 12 is spread upward. Although not shown, the rear member and the front member also have the same structure as the side member and act in the same way as the side member. Hereinafter, the side member will be described as an example. As the side member 12 is unfolded, the size of the box 100 is deformed according to the volume of the article P loaded therein. The upper member 14 located above the article P is lowered down by its own weight and placed on the article P, and the side member 12 is deformed and folded above the article P. Accordingly, the box 100 may be deformed into an appropriate size according to the size of the article P loaded therein.

Here, the strap 52 is positioned next to the side member 12 by being freely moved along the side ring 54 as the side member 12 is unfolded while being fitted in the side ring 54.

In this state, when the operator pulls the strap 52, which is a handle, upward, the strap 52 fixed to the bottom member 10 is pulled and the box 100 is lifted. Accordingly, the operator can easily lift and transport the box 100 deformed to an appropriate size according to the size of the article P.

As described above, the box 100 of the present embodiment is structurally very simple and can be deformed into various sizes, so that various types and sizes of articles P can be loaded, transported and stored.

Although the exemplary embodiments of the present invention have been shown and described as described above, various modifications and other embodiments may be made by those skilled in the art. These modifications and other embodiments are all considered and included in the appended claims and will not depart from the true spirit and scope of the present invention.
