[Prior Art]

 Conventionally, synthetic resin such as plastic has been generally used as a tray for transporting, storing, or displaying products, and it is difficult to recycle and incinerate, which causes problems in disposal. Also, for food packaging and display trays, materials used for food hygiene are limited, and it must be manufactured so that packaging is easy and cost is low. It is restricted. Further, the conventional synthetic resin tray requires a special method for printing and it is difficult to clearly print arbitrary contents, which causes problems in terms of cost and beauty.

[0003]

[Problems to be solved by the device]

 Therefore, the present invention can be easily assembled as a paper box from the folded state and can be used as a tray for transporting, storing, or displaying products, and is also recyclable, eco-friendly, easy to print, and excellent in beauty. Furthermore, it is an object of the present invention to develop a tray made of corrugated ball which is easy to stack and wrap and has excellent heat insulating property, buffer property, water resistance and oil resistance.

[0004]

[Means for Solving the Problems]

 Therefore, the present invention firstly relates to a rectangular bottom wall 1 and two pairs of trapezoidal side walls 2a and 2b and side walls 2c and 2d which are connected to each side of the bottom wall 1 through folding lines. , A pair of triangular flaps 3a, 3b and a flap 3c, which are connected to both ends of the side walls 2c, 2d via fold lines and are connected to both ends of the side walls 2a, 2b via cut lines, The developed paper material P made of corrugated ball composed of 3d is bent to stand up by bending the side walls 2a, 2b, 2c, 2d, and the flaps 3a, 3b, 3c, 3d are superposed on the side walls 2a, 2b. According to Secondly, the corners of the side walls 2a, 2b, 2c, 2d and the flaps 3a, 3b, 3c, 3d are formed in an arc shape. Furthermore, thirdly, it is intended to achieve the above object by making the corrugated ball of functional paper.

[0005]

[Action]

 In the present invention having the above-mentioned structure, first, a rectangular bottom wall is formed on the stepped ball by dividing it by a fold line, and two pairs of trapezoidal side walls are connected to each side of the bottom wall through the fold line. , A triangle-shaped flap is connected to both ends of the pair of side walls with a broken line and a cut line to both ends of the other pair of side walls, and an arc-shaped circle is formed at each corner of the side wall and the flap. Form a developed paper material by adding a mark. Next, each side wall of this expanded paper material is bent to stand up, and the flaps are overlapped with the side wall, so that each side wall is formed into a taper shape that opens upward, so that it is easy to stack and stores. It is easy to store things, has an excellent display effect, and because it is a multi-tiered ball, it is recyclable, environmentally friendly, easy to clearly print the contents of your choice, excellent in cosmetics, and heat-insulating. It is possible to make a tray made of corrugated ball with excellent properties and buffering properties. In addition, it is possible to prevent damage to a packaging wrap or the like by forming an arcuate roundness on each side wall of the upper opening and the corner of the flap. Further, by making the corrugated ball of functional paper, it is possible to obtain excellent water resistance and oil resistance.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings in order to further clarify the gist of the tray made by the present invention. A first embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 shows a developed paper material P for forming a tray B made of corrugated balls from one normal corrugated ball. A rectangular bottom wall 1 is formed by partitioning the bottom wall 1. Two pairs of trapezoidal side walls 2a and 2b and side walls 2c and 2d are connected to each side via a fold line, and the pair of side walls 2c and 2d are connected via a fold line and the other pair of side walls 2a and 2b. A pair of triangular flaps 3a, 3b and 3c, 3d are connected to each other via a cut line, and the side walls 2a, 2b, 2c, 2d and the flaps 3a, 3b, 3c, 3d are connected to each other. The corners are rounded in an arc shape. FIG. 2 is a perspective view of a tray B made of corrugated balls, in which the developed paper material P formed as described above is formed into a taper shape in which each side wall is opened upward. , The side walls 2a, 2b, 2c, 2d are bent to stand up, and the flaps 3a, 3b, 3c, 3d are polymerized and adhered to the outside of the side walls 2a, 2b to form a tray. In this way, since the polymerized adhesive part is on the outside, it is possible to prevent the food items contained in it from being affected. Also, when the polymerized adhesive part is inside, it can be used as a tray by selecting an adhesive that does not affect foods. Furthermore, by wrapping the outer periphery of the entire tray in the state where the flap is polymerized without using an adhesive in the polymerized portion, it becomes possible to use the product as a tray.

Next, the second embodiment is to form a tray made of corrugated balls from corrugated balls made of functional paper, and the construction and operation thereof are the same as those of the first embodiment. For this reason, although illustration is omitted, in addition to the heat insulation and cushioning properties of ordinary corrugated balls, since the corrugated balls are made of functional paper, it is possible to have excellent water resistance and oil resistance. Becomes

The corrugated ball of the developed paper material may be any one-sided or double-sided corrugated ball, or corrugated ball made of functional paper. The shape, size, material, etc. of each constituent element in − may be arbitrarily determined within the range in which the above-mentioned purpose, action, and effect of the invention described later are achieved, and any of these changes are included in the invention. It goes without saying that it does not change the gist of.

[0009]

As described in detail above, the tray made of stepped balls according to the present invention is connected to each side of the rectangular bottom wall by using an arbitrary stepped ball such as one side or both sides. By bending the two pairs of trapezoidal side walls formed and stacking the flaps connected to the pair of side walls on the other pair of side walls, the articles to be packaged can be stored and wrapped as a whole, Further, it is possible to bond the overlapped portion to form a paper box shape. Therefore, since each side wall becomes a taper shape that opens upward, storage and storage in a paper box shape in advance by adhesion are performed. It is easy to stack when transporting, it is easy to store items to be packaged, it has an excellent display effect, and because it is a multi-tiered ball, it is recyclable, environmentally friendly, and has heat insulation and cushioning properties. It becomes possible to be excellent. Further, in the case of wrap packaging, the flap does not have to be adhered in advance, so that the storage and transportation can be performed in a developed form, which is more economical. In addition, it is possible to prevent damage to the wrap or the like to be wrapped by forming arcuate roundness on each side wall of the upper opening and the corner of the flap. Further, since it is a stepped ball, it can be printed easily and clearly, so that it can be made to have excellent aesthetic properties. Furthermore, by making the corrugated ball made of functional paper, it becomes possible to achieve excellent water resistance and oil resistance. As explained above, the present invention has a unique effect which has never been achieved and is a practical and excellent device.
