BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to a packing box having a dish structure allowing the box to be deformed for use as a dish.
2. Description of the Related Art
A box is generally designed to have a size securely accommodating a whole product or item to prevent damage to contents of the box caused by rocking or shock caused by empty space in the box.
Accordingly, the box has a narrow space. This makes it difficult to easily and conveniently put or retrieve an item fitting the box in or from the box.
In addition, disposable boxes are commonly used to pack food or food products. Particularly, boxes for packing of instant food including hamburgers and pizza are usually disposed of without being recycled after use.
For example, boxes used in packing pizza only function to pack the pizza and are not usable as dishes. Thus, separate dishes need be used to serve pieces the pizza.
As described above, boxes used in packing instant food have a disadvantage of requiring separate dishes to be used to eat the packed food.
In addition, most boxes used to pack instant food are formed according to the size of food to be packaged, thereby making it inconvenient to take the food out of the boxes.

Referring to FIGS. 1 to 3, a packing box having a dish structure includes a polygonal bottom portion 100.
Herein, the bottom portion 100 forms a plate-shaped bottom surface and may take any shape selected from among a triangle, quadrangle, pentagon, hexagon and octagon.
The lower surface of the bottom portion 100 is supported on the ground, and various objects to be accommodated such as food or a tool are placed on the upper surface of the bottom portion 100.
In addition, the edge of the bottom portion 100 is provided with a sidewall portion 200 extending from the edge to form a wall member on the bottom portion 100.
The sidewall portion 200 is also provided with a wing portion 300 extending from the sidewall portion 200 to connect the corners of the sidewall portion 200 such that the sidewall portion 200 takes a form unfolded outward on the bottom portion 100.
The packing box also includes a fixing portion 400 formed at the wing portion 300 and the sidewall portion 200 to allow the wing portion 300 and the sidewall portion 200 to be fastened to each other such that the sidewall portion 200 is fixed by being unfolded outward on the bottom portion 100.
As the sidewall portion 200 is formed at the edge of the bottom portion 100 as above, an accommodation space to accommodate an object is formed.
The sidewall portion 200 includes first sidewalls 210 and 210′ extending from opposing sides of the bottom portion 100 and facing each other to form sidewalls on the bottom portion 100 when folded up.
The sidewall portion 200 also includes second sidewalls 220 and 220′ extending from other opposing sides of the bottom portion 100 and facing each other to form the sidewalls on the bottom portion 100.
The corners of the sidewall portion 200 in the longitudinal direction are connected to each other by the wing portion 300 such that the sidewall portion 200 forms a dish shape when partially unfolded to be inclined outward of the bottom portion 100.
That is, when the corners of the sidewall portion 200 in the longitudinal direction are connected by the wing portion 300, the sidewall portion 200 is inclined outward of the bottom portion 100 to form a dish shape.
Herein, the fixing portion 400 is formed at the first sidewalls 210 and 210′ of the sidewall portion 200 and the wing portion 300. Thereby, it allows the wing portion 300 to be fastened to the first sidewalls 210 and 210′ to maintain a dish shape when the sidewall portion 200 is inclined outward of the bottom portion 100 to form the dish shape.
In addition, the first sidewalls 210 and 210′ include inner sidewalls 212 and 212′ extending from the bottom portion 100 and facing each other to form an inner wall member on the bottom portion 100, outer sidewalls 214 and 214′ extending from the inner sidewalls 212 and 212′ to form an outer wall member on the bottom portion 100, and fixing surfaces 216 and 216′ extending from the outer sidewalls 214 and 214′ and fixed to the lower surface of the bottom portion 100.
Herein, the first sidewalls 210 and 210′ and second sidewalls 220 and 220′ of the sidewall portion 200 are vertically erected to form walls on the bottom portion 100, while the fixing surfaces 216 and 216′ of the first sidewalls 210 and 210′ are fixed to the lower surface of the bottom portion 100.
At this time, the fixing surfaces 216 and 216′ are securely fixed to the lower surface of the bottom portion 100 through various adhesive materials including an adhesive and an adhesive tape.
As shown in FIG. 1, when the wing portion 300 is fully introduced into the space formed by overlapping of the inner sidewalls 212 and 212′ and outer sidewalls 214 and 214′ of the first sidewalls 210 and 210′, the first sidewalls 210 and 210′ and the second sidewalls 220 and 220′ are perpendicularly erected on the bottom portion 100 generally in the form of a box shape, and an object to be accommodated is accommodated in the box shape.
As shown in FIG. 2, when the wing portion 300 is partially withdrawn from the space formed by overlapping of the inner sidewalls 212 and 212′ and outer sidewalls 214 and 214′ of the first sidewalls 210 and 210′ and is connected and fixed to the first sidewalls 210 and 210′ and the second sidewalls 220 and 220′ by the fixing portion 400, the first sidewalls 210 and 210′ and the second sidewalls 220 and 220′ are erected by being inclined outward of the bottom portion 100. As the sidewall portion 200 is held inclined with respect to the bottom portion 100, the box shape is transformed into a dish shape and thus the box forming the dish shape may be used as a dish.
To this end, the section in which the bottom portion 100 is connected to the inner sidewalls 212 and 212′ is provided with first bottom boundary lines 150 and 150′ to guide the inner sidewalls 212 and 212′ such that the inner sidewalls 212 and 212′ are folded in with respect to the bottom portion 100, as shown in FIG. 3.
In addition, the section in which the inner sidewalls 212 and 212′ are connected to the outer sidewalls 214 and 214′ is provided with inner wall boundary lines 215 and 215′ to guide the outer sidewalls 214 and 214′ such that the outer sidewalls 214 and 214′ are folded out with respect to the inner sidewalls 212 and 212′.
Further, the section in which the outer sidewalls 214 and 214′ are connected to the fixing surfaces 216 and 216′ is provided with outer wall boundary lines 217 and 217′ to guide the fixing surfaces 216 and 216′ such that the fixing surfaces 216 and 216′ are folded out with respect to the outer sidewalls 214 and 214′.
The section in which the second sidewalls 220 and 220′ forming the other sidewalls on the bottom portion 100 are connected to the bottom portion 100 is provided with second bottom boundary lines 170 and 170′ to guide the second sidewalls 220 and 220′ such that the second sidewalls 220 and 220′ are folded in with respect to the bottom portion 100.
Meanwhile, the wing portion 300 extends from the second sidewalls 220 and 220′ and is formed between the boundary surfaces of the first sidewalls 210 and 210′ and the second sidewalls 220 and 220′ vertically adjoining each other such that the wing portion 300 is inserted into or withdrawn from a space formed by folding the first sidewalls 210 and 210′ in an overlapping manner when the first and second sidewalls 210, 210′, 220 and 220′ are erected on the bottom portion 100.
The wing portion 300 includes a moving surface 310 extending in a fan shape from the second sidewalls 220 and 220′ and moving inside the first sidewalls 210 and 210′, and a fold surface 320 extending from the moving surface 310 and folded inward of the moving surface 310.
Herein, the moving surface 310 extends from the second sidewalls 220 and 220′, and the fold surface 320 is disposed in parallel with the first sidewalls 210 and 210′ and cut off from the first sidewalls 210 and 210′.
To this end, the section in which the second sidewalls 220 and 220′ are connected to the moving surface 310 is provided with a movement boundary line 315 to guide the moving surface 310 such that the moving surface 310 is folded in with respect to the second sidewalls 220 and 220′.
In addition, the section in which the moving surface 310 is connected to the fold surface 320 is provided with a fold boundary line 325 to guide the fold surface 320 such that the fold surface 320 is folded in with respect to the moving surface 310.
In this configuration, when the sidewall portion 200 is inclined outward of the bottom portion 100 with the wing portion 300 connecting the corners of the sidewall portion 200 in the longitudinal direction, the bottom portion 100 and the sidewall portion 200 form a dish shape.
The fixing portion 400 includes a fixing segment 410 formed at the wing portion 300 and a fixing groove 420 formed at the sidewall portion 200 by perforating the sidewall portion 200 to allow the fixing segment 410 to be fixed when introduced into the fixing groove 420.
The fixing segment 410 is coupled to the fixing groove 420 such that the wing portion 300 is fixed after being partially withdrawn from the inner space formed by folding the sidewall portion 200.
In this way, the wing portion 300 is securely fixed in the space between the neighboring boundary lines of the first sidewalls 210 and 210′ and the second sidewalls 220 and 220′ with the sidewall portion 200 erected on the bottom portion 100 and disposed inclined outward of the bottom portion 100 through the configuration of the fixing portion 400.
As a result, as the wing portion 300 is fixed by being withdrawn from the space formed by overlapping the inner sidewalls 212 and 212′ and the outer sidewalls 214 and 214′ of the first sidewalls 210 and 210′ with the sidewall portion 200 erected on the bottom portion 100, the sidewall portion 200 is inclined with respect to the bottom portion 100 to generally form a dish shape.
FIG. 4 is a view illustrating main parts of a packing box having a dish structure according to one embodiment of the present invention.
Referring to FIG. 4 in addition to FIGS. 1 to 3, the bottom portion 100 has a quadrangular shape. Thereby, the sidewall portion 200 forms a quadrangular box shape when vertically erected on the bottom portion 100.
At this time, if the wing portion 300 is drawn out of the interior of the sidewall portion 200 and fixed in the withdrawn position through the fixing portion 400, the sidewall portion 200 erected and inclined outward of the bottom portion 100 forms a dish shape.
The sidewall portion 200 includes first sidewalls 210 and 210′ extending from opposite sides of the bottom portion 100 and facing each other to form sidewalls on the bottom portion 100 when folded up.
The sidewall portion 200 also includes second sidewalls 220 and 220′ extending from the other opposing sides of the bottom portion 100 and facing each other to form the other sidewalls on the bottom portion 100.
The first sidewalls 210 and 210′ include inner sidewalls 212 and 212′ extending from the bottom portion 100 and facing each other to form inner walls on the bottom portion 100, outer sidewalls 214 and 214′ extending from the inner sidewalls 212 and 212′ to form outer walls on the bottom portion 100, and fixing surfaces 216 and 216′ extending from outer sidewalls 214 and 214′ and fixed to the lower surface of the bottom portion 100.
In addition, the corners of the sidewall portion 200 in the longitudinal direction are connected to each other by the wing portion 300 such that the sidewall portion 200 forms a dish shape when inclined outward of the bottom portion 100 by being partially unfolded.
The wing portion 300 includes a moving surface 310 extending in the shape of a fan from the second sidewalls 220 and 220′ and adapted to move inside the first sidewalls 210 and 210′, and a fold surface 320 extending from the moving surface 310 and adapted to be folded inward of the moving surface 310.
In addition, a fixing portion 400 is formed at the wing portion 300 and the sidewall portion 200 to allow the wing portion 300 and the sidewall portion 200 to be fastened to each other such that the sidewall portion 200 is fixed by being unfolded outward of the bottom portion 100.
The fixing portion 400 includes a fixing segment 410 formed at the wing portion 300 and a fixing groove 420 formed at the first sidewalls 210 and 210′ by perforation to allow the fixing segment 410 to be fixed when introduced into the fixing groove 420.
Herein, the fixing portion 400 is formed at the first sidewalls 210 and 210′ of the sidewall portion 200 and the wing portion 300. Thereby, the wing portion 300 can be fastened to the first sidewalls 210 and 210′ to maintain a dish shape when the sidewall portion 200 is inclined outward of the bottom portion 100 to form the dish shape.
The process of transformation from the box shape into the dish shape is performed in a manner described below. The inner sidewalls 212 and 212′ of the first sidewalls 210 and 210′ are vertically erected on the bottom portion 100, and the outer sidewalls 214 and 214′ are folded with respect to the inner sidewalls 212 and 212′ such that the inner sidewalls 212 and 212′ and the outer sidewalls 214 and 214′ overlap each other with a space formed therebetween.
Then, the fixing surfaces 216 and 216′ are folded with respect to the outer sidewalls 214 and 214′ such that the fixing surfaces 216 and 216′ contacts the lower surface of the bottom portion 100.
Herein, the fixing surfaces 216 and 216′ are fixed to the lower surface of the bottom portion 100 by an adhesive material.
At the same time, the second sidewalls 220 and 220′ are vertically erected on the bottom portion 100, and the fold surface 320 is folded in with respect to the moving surface 310 of the wing portion 300 extending from the second sidewalls 220 and 220′.
Herein, the fold surface 320 is folded about the fold boundary line 325 with respect to moving surface 310. The fold surface 320 may be folded out with respect to the moving surface 310 as desired by the user.
At this time, the moving surface 310 is folded by moving from the second sidewalls 220 and 220′ toward the first sidewalls 210 and 210′.
That is, the wing portion 300 is introduced into the space between the inner sidewalls 212 and 212′ and the outer sidewalls 214 and 214′ of the first sidewalls 210 and 210′.
Subsequently, the moving surface 310 may be withdrawn from the space between the inner sidewalls 212 and 212′ and the outer sidewalls 214 and 214′ such that the fixing segment 410 of the fixing portion 400, which is formed at the fold surface 320, is fastened to the fixing groove 420 formed in the section in which the inner sidewalls 212 and 212′ and the outer sidewalls 214 and 214′ are connected to each other.
Once the fixing segment 410 is fastened to the fixing groove 420, the first sidewalls 210 and 210′ and the second sidewalls 220 and 220′ are inclined with respect to the bottom portion 100, forming a dish shape.
In addition, when the wing portion 300 is introduced into the space between the inner sidewalls 212 and 212′ and the outer sidewalls 214 and 214′, the overall shape is transformed from a dish shape into a box shape.
