Therefore, the shapes and the like of the elements in the drawings can be exaggeratedly expressed to emphasize a clearer description. It should be noted that the same members in each drawing are sometimes shown with the same reference numerals. Detailed descriptions of known functions and configurations that may be unnecessarily obscured by the gist of the present invention are omitted.

1 is a perspective view showing the configuration of a paper chopsticks 100 according to the present invention. As shown, the paper chopsticks 100 according to the present invention are manufactured by assembling a plurality of paper chopstick bodies 110, 120, 130, 140, and 150 having different sizes from each other. Accordingly, the paper chopsticks 100 is assembled in the form of a fishing rod as a whole.

Each paper chopstick body (110,120,130,140,150) is formed in a conical shape in which the upper diameter is larger than the lower diameter. At this time, each of the paper chopstick body (110,120,130,140,150) is open to the lower region and the upper region is inserted into the upper region of the neighboring paper chopstick body (110,120,130,140,150) is exposed to the outside through the lower region.

That is, the fourth paper chopsticks body 140 is inserted through the upper region of the fifth paper chopsticks body 150, and the third paper chopsticks body 130 is inserted into the upper region of the fourth paper chopsticks body 140. The second paper chopsticks main body 120 is inserted into the upper part of the third paper chopsticks body 130, and the first paper chopsticks main body 110 is sequentially inserted into the upper part of the second paper chopsticks body 120.

Each paper chopstick body 110, 120, 130, 140, 150 is assembled in a multi-stage in such a way that the small diameter paper chopstick body is exposed to the outside through the lower region of the paper chopstick body having a relatively large diameter by the diameter difference.

2A to 2B are exploded views and assembling views of the first paper chopstick body 110 forming the paper chopsticks 100, and FIG. 2C is a cross-sectional view illustrating a cross-sectional configuration along the line A-A of FIG. 2B. Here, since the configuration of each paper chopsticks body 110, 120, 130, 140, 150 is the same as the first paper chopsticks body 110, only the first paper chopsticks body 110 will be described in detail.

The first paper chopsticks body 110 is formed of waterproof paper. Waterproof paper is produced by forming a waterproof coating layer on the outer side of the paper layer. Even if the paper chopsticks 100 are in contact with food by the waterproof coating layer, the paper chopsticks 100 may be prevented from being bent or deformed. In particular, the waterproof paper used in the paper chopsticks 100 according to the present invention may be provided with a polyart.

The first paper chopsticks body 110 is provided in a cylindrical shape with the top and bottom open in an assembled state. In some cases, the upper part may be opened and the lower part may be provided in a closed cylindrical shape. To this end, the first paper chopsticks body 110 is assembled by rolling one side 117 of the side surface 112 into the other side 115 in an expanded view form as shown in FIG. 2A. That is, one side 117 is rolled to the inside of the other side 115 without engaging one side 117 and the other side 115 to be in contact so that the side surface 112 of the cylinder is plural, as shown in FIG. To be formed. As a result, the thickness of the first paper chopstick body 110 may be increased, thereby improving strength.

In particular, since the first paper chopsticks body 110 is located in the lowest region of the paper chopsticks 100, the food is directly held. Accordingly, the strength needs to be larger than that of other areas. The first paper chopsticks body 110 has a thicker side 112 than the remaining paper chopsticks body 120, 130, 140, 150.

At this time, since the first paper chopsticks body 110 is formed to have a smaller diameter than the remaining paper chopsticks bodies 120, 130, 140, and 150, one side 117 is relatively dried to the other side 115 than the remaining paper chopsticks bodies 120, 130, 140, and 150. The length becomes long. Accordingly, the thickness d1 of the side surface 112 of the first paper chopstick body 110 may be thicker than the thicknesses of the remaining paper chopsticks bodies 120, 130, 140, and 150.

In addition, the lower region 111 having a relatively smaller diameter than the upper region 113 has the longest length of the paper chopsticks body 110, 120, 130, 140, and 150 in which the paper is curled, so that the thickness of the sidewall is thickest. Preferably, the lower region 111 may be formed in a form in which the inside is filled by the side surface 112. As a result, even if the food is gripped with strength, the shape can be easily prevented from being deformed.

Here, when the diameter of the paper chopsticks main body 110, 120, 130, 140, 150 is adjusted by adjusting the degree of winding the side by using the same development, the thickness of the side of the paper chopsticks main body 110, 120, 130, 140, 150 becomes thinner.

In order to prevent this, the paper chopsticks main body 110, 120, 130, 140, 150 may be formed to have the same thickness by using the development of different sizes separately.

On the other hand, the diameter of the first paper chopsticks body 110 becomes the length R of the cylinder on a developed view. The lower region 111 and the upper region 113 are formed to have different arc lengths so that the diameter l1 of the lower region 111 is smaller than the diameter 12 of the upper region 113 at the time of assembly.

Each paper chopstick body (110,120,130,140,150) is provided with a larger diameter gradually from the bottom to the top. Thereby, the paper chopsticks main body 110, 120, 130, 140 located in the lower portion is inserted into the paper chopsticks main body 120, 130, 140, 150 located in the upper portion.

At this time, the paper chopsticks body (110, 120, 130, 140) located in the lower portion of the paper chopsticks body (120, 130, 140, 150) located in the upper portion is preferably inserted for strength reinforcement.

That is, as shown in FIG. 3, the length h1 corresponding to half of the lower part of the entire length R2 of the second paper chopstick body 120 is provided to surround the outside of the first paper chopstick body 110. The length h2 corresponding to half of the lower half of the total length R3 of the three paper chopsticks body 130 surrounds the outside of the second paper chopsticks body 120 and the entire length of the fourth paper chopsticks body 140 (R4). The length (h3) corresponding to half of the) wraps around the outside of the third paper chopsticks body 130, and the length (h4) corresponding to half of the total length (R5) of the fifth paper chopsticks body 150 is the fourth paper. The chopsticks body 140 is provided to surround the outside.

When the paper chopsticks main body 110, 120, 130, 140, 150 is inserted into the stack in multiple stages in this way, the thickness of the paper chopsticks main body (120, 130, 140, 150) wrapped at the top is added to the thickness of each paper chopsticks main body (110, 120, 130, 140, 150) paper chopsticks (100) ) Is further improved. Therefore, when the user picks up food by holding paper chopsticks, durability and strength can be maintained even after a certain time. In addition, since the side 112 is formed in a plurality of layers, even if the water is absorbed to the outermost it takes time to be absorbed by the inner side of the curled, so the deformation of the paper chopsticks 100 is reduced.

Here, the diameter of the upper region of the paper chopstick body (110, 120, 130, 140) located in the lower portion is preferably provided to be locked to the center region of the paper chopstick body (120, 130, 140, 150) overlapping the upper portion.

For example, the diameter l2 of the upper region of the first paper chopstick body 110 is formed larger than the diameter l3 of the lower region of the second paper chopstick body 120 and smaller than the diameter l4 of the upper region. When the first paper chopsticks body 110 is inserted into the second paper chopsticks body 120, the first paper chopsticks body 110 is locked to the center region of the second paper chopsticks body 120.

Due to this structure, the paper chopsticks body located at the bottom is fixed to the inside of the paper chopsticks body located at the top, thereby preventing the plurality of paper chopsticks bodies from being separated when used by the user. In particular, such a laminated structure can be maintained in a stable assembly state without being separated from each other because the paper chopsticks body is assembled under a force in the downward direction.

The assembly process and the use process of the paper chopsticks 100 according to the present invention having such a configuration will be described with reference to FIGS. 1 to 4B.

Paper chopsticks 100 according to the present invention may be provided to the user is packaged in a state of assembling is completed, or coupled to a product that is used for single use outdoors such as cup noodles or lunch boxes.

As shown in FIG. 4A, the paper chopsticks 100 are packaged in a state in which the paper chopstick bodies 110, 120, 130, 140, and 150 are stacked inside each other.

Due to the difference in diameter between each of the paper chopsticks (110, 120, 130, 140, 150) is arranged in a state accommodated inside each other. When the packaging material is removed in this state, as shown in FIG. 4B, the small diameter paper chopstick bodies are exposed to the outside of the large diameter paper chopstick body by gravity.

That is, the first paper chopsticks body 110 is exposed to the outside of the second paper chopsticks body 120 at the upper portion, and the second paper chopsticks body 120 is exposed to the outside through the lower portion of the third paper chopsticks body 130 at the top. Is exposed.

When the paper chopsticks are exposed to the outside, the length of the paper chopsticks is elongated, and the user can grasp food in the stretched state. On the other hand, the finished paper chopsticks 100, as shown in Figure 4a when applying a force from the bottom to the upper paper chopsticks main body 110, 120, 130, 140, 150 back to the inside of the large diameter paper chopsticks main body (110, 120, 130, 140, 150) The length can be reduced by inserting.

Paper chopsticks 100 according to the present invention is manufactured by assembling five paper chopsticks main body (110, 120, 130, 140, 150) laminated, but can add or subtract the number of paper chopsticks main body according to the purpose of use and the type of food,

Each paper chopstick body (110, 120, 130, 140, 150) is rolled up a plurality of fan-shaped developments to form a thick side of the side 112 to reinforce the strength. In addition, the thickness may be doubled while being inserted into each other to further increase the strength. And the position can be fixed inside while being inserted into each other by the difference in diameter.

On the other hand, Figure 5 is a perspective view showing the configuration of a paper chopsticks (100 ') according to another embodiment of the present invention. Paper chopsticks 100 according to a preferred embodiment of the present invention described above made a conical shape of the cross section of each of the paper chopsticks main body (110,120,130,140,150).

On the other hand, the paper chopsticks 100 ′ according to another embodiment of the present invention are formed to have a cross-sectional area. Even in this case, the cross-sectional area is gradually increased from the lower part to the upper part, and the plurality of paper chopstick bodies are assembled to be stacked in a multi-stage manner.

In addition, paper chopsticks may be formed in various shapes such as triangles and pentagons in addition to squares.

As described above, the paper chopsticks according to the present invention may be manufactured by assembling a conical paper chopstick body of waterproof paper material in a multistage manner. As a result, the manufacturing process may be simplified, and in some cases, the user may assemble and use the same.
