1 is a perspective view of a box 1 according to an embodiment of the present invention. 2 is a front view of a box 1 according to an embodiment of the present invention. 3 is a plan view of a box 1 according to an embodiment of the present invention.

Referring to the drawings, a box 1 according to an embodiment of the present invention includes a bottom portion 10 and a side portion 20. In addition, the side part 20 is formed with a five line 24 and a fold line 25. The bottom part 10 and the side part 20 may be made of paper, and the inner side may be coated with polyethylene to have moisture resistance.

Bottom (10)

The bottom portion 10 is formed in a plate shape. The bottom portion 10 may be formed in a disk shape, among others, and may have a coupling portion (11 in FIG. 4) that can be coupled to the side portion 20 to be described later on the rim. The coupling part 11 may be folded in a direction that is not parallel to the bottom part 10 and adhered to the inner surface of the side part 20 using an adhesive, but the method of combining the bottom part 10 with the side part 20 Not limited to this.

side (20)

The side part 20 is a component forming the side of the box 1 according to one embodiment of the present invention. Box 1 in which liquids (P in FIG. 7) can be accommodated in such a way that an inner space 26 surrounded by side parts 20 is formed and the bottom part 10 closes one side of the inner space 26 is formed Here, the liquid material P may include a paste having viscosity and a liquid such as water having relatively low viscosity.

The side portion 20 extends from the bottom portion 10 in one direction. Specifically, the longitudinal section of the side portion 20 is formed to have a profile toward the outside of the bottom portion 10 as it moves away from the bottom portion 10 along a direction perpendicular to the bottom portion 10 . Therefore, one direction in which the side portion 20 extends from the bottom portion 10 is one direction having both a component in a direction perpendicular to the bottom portion 10 and a component in an outward direction of the bottom portion 10 . As the side part 20 is formed in this way, the size of the cross section cut through the side part 20 in a plane parallel to the bottom part 10 will be farther away from the bottom part 10 along the direction perpendicular to the bottom part 10. the bigger it can be. That is, the side portion 20 may have a tapered longitudinal cross-section in which a width in a plane parallel to the bottom portion 10 decreases as it approaches the bottom portion 10 . This can be confirmed in FIG. 2 .

The side portion 20 may be formed such that a profile of a cross section cut in a plane parallel to the bottom portion 10 forms a closed curve. Accordingly, an internal space 26 surrounded by the side portion 20 is formed, and the liquid material P may be accommodated in the internal space 26 . The shape of the plane cut by cutting the side portion 20 in a plane parallel to the bottom portion 10 may be circular, like the shape of one surface of the bottom portion 10 .

The inner space 26 formed by the side portion 20 may be formed in the shape of a truncated cone, such as the end of a cone, and the liquid material P may be accommodated therein. However, the shape of the side portion 20 and the inner space 26 is not limited thereto. However, the inner space 26 may contain a solid material or powder other than the liquid material P. The inner space 26 is surrounded by the side portion 20 as described above and the lower end is covered by the bottom portion 10. However, the upper end 22 of the side portion is opened to form an opening 27 through which the liquid P enters and exits the inner space 26 . The shape of the opening 27 may be formed in a circular shape like the cross-sectional shape of the side portion 20 .

The side portion 20 may be formed in a form in which both ends 201 and 202 of a strip-shaped paper material in the longitudinal direction are overlapped and combined with each other. A process of forming the side portion 20 will be described in detail in the description of FIGS. 5 and 6 .

The upper end 22 of the side part, on the outside of the side part 20, may be rolled in the other direction opposite to the one direction in which the side part 20 extends from the bottom part 10. In this way, a portion formed by curling the upper end 22 of the side portion is referred to as a curl 221. As the curl 221 is formed on the upper end 22 of the side part, even when a body part such as a user's finger or lip contacts the upper end 22 of the side part, it is possible to prevent injury caused by the cut surface of a sharp material. In addition, it is possible to prevent the upper end 22 of the side part from being worn by friction.

Static lines (24) and fold lines (25)

On the side portion 20, a staggered line 24 and a fold line 25 are formed. The line of sight 24 is a line formed from the top 22 of the side portion forming the open opening 27 along the opposite direction to one direction in which the side portion 20 extends from the bottom portion 10. . Fold lines 25 are formed in the same way, and are formed at respective locations spaced apart on both sides of the line of sight 24 along the circumferential direction of the side portion 20, and a total of two are disposed on the side portion 20.

The line of sight 24 and the line of fold 25 are formed by pressing the side portion 20 . Specifically, the line of sight 24 is formed in a form protruding outward by embossing the side portion 20 from the inside to the outside of the side portion 20 . Contrary to this, the fold line 25 is formed in a form protruding to the inside of the side portion 20 by pressing the side portion 20 from the outside to the inside of the side portion 20 .

As the side portion 20 is pressed in this form to form the line of sight 24 and the fold line 25, a partial region of the side portion 20 adjacent to the fold line 25 may be pressed to the inside of the side portion 20. When the line of sight 24 is formed, the other portion of the side portion 20 protrudes outward from the side portion 20, thereby forming the spout 29. Since there are the line of sight 24 and the line of fold 25 formed by pressing, when the side 20 is pressed, the positions corresponding to the line of sight 24 and the line of fold 25 are different from those of the other side 20. Better folds outward and inward of the side 20 . Therefore, it is easy to form the spout (29 in FIG. 8) at a predetermined position. This method of forming the spout 29 by pressing the side portion 20 will be described in detail in the description of FIGS. 7 and 8 .

The line of sight 24 extends from the lower end 222 of the curl located below the curl 221 of the upper end 22 of the side part, but does not extend long enough to contact the lower end 21 of the side part, and has a predetermined length. have Likewise, the fold line 25 also has a different predetermined length from the lower end 222 of the curl located at the upper end 22 of the side part to the extent that it does not contact the lower end 21 of the side part.

Specifically, along one direction in which the side portion 20 extends, the length L1 of the line of sight 24 may be 1/2 or less and 1/7 or more of the height L3 of the side portion 20 . In one example, the length L1 of the line of sight 24 may be 45 mm.

As the line of sight 24 is formed longer than the line of fold 25, when the side portion 20 is pressed, the spout 29 protruding outward around the line of sight 24 can be easily formed .

The distance D between the line of sight 24 and the line of fold 25 may be formed to be 1/6 or less and 1/16 or more of the length of the circumference of the side portion 20 . Therefore, when pressing the side portion 20 to form the spout 29, the fold line 25 and the fold line 25 are spaced apart by an excessively large distance from each other, which is not suitable for collecting and discharging the liquid (P). It is possible to prevent a situation in which an angled spout 29 is formed. For example, the distance D between the line of sight 24 and the line of fold 25 may be 50 mm. When the user grips the side 20 of the box 1 and presses the area adjacent to the fold line 25, the user will mainly try to press with the thumb and forefinger. At this time, if the area adjacent to the fold line 25 is pressed by a normal adult's hand, the above-described distance between the line of sight 24 and the fold line 25 must have each other so that the pressure can be easily applied.

Hereinafter, a method of forming the cardboard box 1 according to an embodiment of the present invention will be described with reference to the drawings.

Figure 4 is a perspective view of the bottom portion 10 according to an embodiment of the present invention.

A method of forming the box 1 according to an embodiment of the present invention may start with preparing the bottom portion 10. The bottom portion 10 may be formed by cutting and folding the paper material formed through the printing process in the same shape as the bottom portion. As described above, the coupling portion 11 bonded to the side portion 20 may be formed by folding the edge of the bottom portion 10 in a direction perpendicular to the bottom portion 10 . The coupling portion 11 may be formed for each partial area by segmenting the entire edge of the bottom portion 10, not the entire edge.

5 is a development view of a strip-shaped material 200 according to an embodiment of the present invention.

Side 20 may be prepared. The step of preparing the side part 20 may be performed after the step of preparing the bottom part 10 is executed, may be performed before that, or may be performed simultaneously.

The side portion 20 is formed of a strip-shaped material 200 . The strip-shaped material 200 may be formed in the same shape as a large fan shape by deleting a small fan shape having the same included angle. The strip-shaped material 200 may be formed by cutting and folding a paper material in the same manner as the bottom portion 10 . The strip-shaped material 200 may have a region 240 to be pressed and become a five line and a region 250 to be two fold lines. As shown in the drawing, the strip-shaped material 200 may be molded before becoming the side portion 20, and may have an area 240 to be a five-line line and an area 250 to be a fold line, as shown in FIG. 6 to be described later. After this joining to become the side part 20, the side part 20 is molded, and may have a five line 24 and two fold lines 25.

As shown, an area 240 to be a quintessential line and an area 250 to be a fold line are formed from a place adjacent to one end of the strip-shaped material 200 in the width direction to the other side. The area 240 to be the quintessential line and the area 250 to be the fold line are spaced apart from one end of the strip-shaped material 200 in the width direction, thereby preparing an area where the curl 221 can be formed. In addition, an area 250 to be two fold lines and an area 240 to be a five-line line are spaced apart from one end 201 in the longitudinal direction of the strip-shaped material 200 by a predetermined distance. Here, the predetermined interval may be 1/4 of the length of the strip-shaped material 200 . With the area 240 to be the stigma as the center, the area 250 to be the fold line may be disposed at symmetrical positions.

Therefore, after joining both ends of the strip-shaped material 200, the line of sight 24 is formed in a form extending from the upper end 22 of the side part forming the open opening 27 toward the bottom part 10. In addition, the fold lines 25 extend from the upper end 22 of the side part toward the bottom part 10 at each spaced apart on both sides of the line of sight 24 along the circumferential direction of the side part 20. is formed

If the line of sight 24 and the fold line 25 are formed after the side part 20 is formed, the position of the line of sight 24 predetermined on the side part 20 is molded from the inside to the outside to form the line of sight line 24 Forming, and forming the fold line 25 by pressing the predetermined position of the fold line 25 from the outside to the inside.

Figure 6 is a perspective view showing a situation in which the side portion 20 and the bottom portion 10 are coupled according to an embodiment of the present invention.

In order to form the side portion 20, both ends 201 and 202 of the strip-shaped material 200 in the longitudinal direction are overlapped and combined. The lower end 21 of the provided side portion may be coupled to one side or edge of the bottom portion 10 . The above-described coupling portion 11 of the bottom portion 10 and the inner surface of the lower end 21 of the side portion are coupled to form the support box 1 by combining the side portion 20 and the bottom portion 10.

In one embodiment of the present invention, the side portion 20 and the bottom portion 10 are separately formed and combined to form the paper box 1, but the paper material is cut in the same form as the development of the paper box 1, It is also possible to form an integrated box (1).

As both ends 201 and 202 of the strip-shaped material 200 in the longitudinal direction overlap, an overlapping portion 28 is formed. One end 201 in the longitudinal direction of the strip-shaped material 200 may be covered on the outside of the other end 202 and coupled by a bonding means such as an adhesive. However, one end 201 in the longitudinal direction may be coupled to the inside of the other end. In addition, after one end 201 in the longitudinal direction of the strip-shaped material 200 is covered on the outside of the other end 202 to form the side portion 20, the lower end 21 of the side portion is folded to the inside of the side portion 20 to form the bottom portion ( 10) may be combined with the coupling part 11.

As shown, the line of sight 24 may be located at a location spaced apart from the overlapping portion 28 where both ends of the strip-shaped material 200 overlap. Specifically, when the upper end 22 of the side of the box 1 forms a circular profile, the line segment connecting the center of the circle and the place where the line of sight 24 is located, and the A line segment connecting the center of the circle and the overlapping portion 28 may be disposed at a location forming a right angle to each other. Since the overlapping portion 28 is formed thicker compared to other areas of the side portion 20, it is less likely to fold. However, since the strip-shaped material 200 is a portion bonded by an adhesive or the like, when pressure is applied to the overlapping portion 28 from both sides, the side portion 20 may be damaged as the adhesion is released. Therefore, when the line of sight 24 is disposed in an area forming a right angle from the overlapping portion 28 and one of the fold lines 25 is disposed adjacent to it, no pressure is applied around the overlapping portion 28, and the overlapping portion ( 28) and pressurization will be made to the inside of the box 1 for the adjacent area. In this case, the overlapping portion 28 is not damaged and the adhesive surface can be maintained intact.

After the line of sight 24 and the fold line 25 are formed, the top 22 of the side portion may be rolled from the outside of the side portion 20 toward the bottom portion 10 to form a curl 221 . After first forming a curl 221 by rolling one end of the strip-shaped material 200 forming the side portion 20 in the width direction, and then bonding both ends 201 and 202 of the strip-shaped material 200 in the longitudinal direction, the side portion 20 ) may be formed. Accordingly, the line of sight 24 and the line of crease 25 may start from the lower end 222 of the curl and extend toward the bottom 10 along the side 20 .

The box 1 is prepared through the above process. After the paper box 1 is prepared, the liquid material P may be accommodated in the inner space 26 through the opening 27 of the paper box 1, and the powder may be mixed with the liquid to form the liquid material P. this may be acceptable.

After the liquid material P is accommodated in the inner space 26, a product using the paper box 1 may be manufactured by sealing the opening 27 of the paper box 1 with a cover (not shown). The cover may include a plate-shaped cover portion and an annular circumferential portion extending vertically downward from an edge of the cover portion. The thickness of the circumference is such that when the cover covers the opening 27 and is coupled to the upper end 22 of the side, the end of the circumference is located at the same height as the fold line 25 or higher in the vertical direction. can In addition, the end of the circumferential portion may be formed in a form spaced apart from the side portion 20 of the box 1 to the outside. In addition, when the cover is coupled to the upper end 22 of the side portion, the circumferential portion may be coupled while pressing the curl 221 toward the inside of the paper box 1. The cover may be made of plastic, but the material is not limited thereto.

In addition, a packaging film surrounding the cover and the paper box 1 may be included. By surrounding the cover and the paper box 1 with the packaging film, the line of sight 24 and the fold line 25 of the paper box 1 are prevented from being pressed and leading to deformation of the side portion 20 in a state in which the cover is not separated. can

7 is a perspective view showing a situation in which the side portion 20 is pressed to fold the box 1 according to an embodiment of the present invention. 8 is a perspective view showing a folded state of the cardboard box 1 according to an embodiment of the present invention.

If the user uses the above-mentioned product, the step of removing the cover from the side 20 is preceded. In a state where the liquid material P is accommodated in the bin 1, the user may try to pour the liquid material P. The liquid material P may have flowed into the box 1 through the opening 27 in the process of manufacturing the product, but is formed on the inside of the side 20 of the box 1 in the powder that the box 1 accommodates. The liquid (P) may be formed by pouring and stirring the liquid up to the water line (not shown). The water line is formed parallel to the bottom part 10 at a certain height of the side part 20 . The water line may be formed by protruding or sinking by pressing the side portion 20, or may be printed. When a paste, which is an example of the liquid P, is formed by stirring the liquid and the powder, a predetermined time may be waited so that the paste can absorb the liquid well.

In order to easily discharge the liquid material P, a spout 29 may be formed in the paper box 1. Partial regions of the side portions 20 adjacent to the fold lines 25 are pressed in a direction in which they become closer to each other. The direction in which the pressure is applied is toward the inner side of the side portion 20, but in a direction in which they become closer to each other.

As some areas of the side portion 20 adjacent to the fold lines 25 are pressed, other portions of the side portion 20 where the lines of sight 24 are formed protrude outward from the side portion 20 compared to the adjacent areas. This is because some areas adjacent to the fold lines 25 are depressed to the inside of the side portion 20 . Since the fold line 25 and the stipple line 24 are provided in a molded state, when the side portion 20 is pressed, the side portion 20 is better bent in that area than in other areas, so that the spout 29 has a predicted shape. ) is easily formed. The area protruding outward becomes the spout 29 .

Figure 9 is a front view showing a situation in which the liquid (P) is leaked to the spout (29) by tilting the box (1) according to an embodiment of the present invention.

The drawer (1) is tilted so that the liquid (P) flows out through the spout (29). The box 1 is tilted so that the spout 29 is directed downward, so that the liquid P is discharged to the outside along the spout 29. The spout 29 is formed without collapsing the shape of the paper box 1, so that the liquid P can be easily discharged to a desired location along the spout 29.

In one embodiment of the present invention, when the liquid material (P) accommodated in the paper box (1) is the whole dough, after putting cooking oil on the heated frying pan, the whole dough is drained from the paper box (1) into the frying pan in the above-described method, , Jeon can be prepared by heating and frying the former dough on a frying pan. The dough may be potato pancake, zucchini pancake, green onion pancake, or kimchi pancake, but the type of dough is not limited thereto.

The above-described method for discharging the liquid P and the previous manufacturing method may be described on the outer surface of the side 20 of the box 1. Therefore, such information may be written on the side portion 20 in the printing step, and a label having one side printed with information and the opposite side to which an adhesive is applied may be adhered to the side portion 20 . A pre-manufacturing kit including a box 1 having such information written thereon and a liquid material P or contents capable of forming the liquid material P may be provided.
