Description

Technology Field

[0001] The present invention relates to a paper container, and more specifically, to a sauce storage space convertible container that can form a sauce storage space when necessary by utilizing a double paper structure formed on one side of the container body. Background Technology

[0002] Generally, paper containers used in fast food restaurants or convenience stores are widely used to hold and serve various foods such as french fries, chicken nuggets, and popcorn. Consumers frequently eat these foods with sauces such as ketchup, mustard, and chili sauce, but conventional paper containers do not have a separate space to store the sauces.

[0003] As a result, consumers have to receive a separate sauce container, or pour the sauce directly into the container, causing the food to become excessively soaked in the sauce. In addition, using a separate sauce container generates additional waste such as plastic or paper, which is not environmentally desirable.

[0004] Meanwhile, although there have been conventional attempts to form a sauce storage space in containers, there were problems such as increased manufacturing costs and reduced production efficiency due to the need to combine additional separate parts or require complex assembly processes. The problem to be solved

[0005] The present invention was devised to solve the problems of the conventional technology described above, and aims to provide a sauce storage space convertible container that can form a sauce storage space solely by folding a double paper structure formed on one side of the container body without the addition of separate parts.

[0006] In addition, another objective of the present invention is to provide a sauce storage space convertible container that folds into a flat state when the sauce storage space is not in use, so as not to damage the appearance of the container, and can form a sauce storage space with a simple operation when needed.

[0007] In addition, another objective of the present invention is to provide a sauce storage space convertible container capable of securing structural stability of the sauce storage space by having a protrusion that limits the protrusion range of the sauce storage space. means of solving the problem

[0008] According to one embodiment of the present invention, a sauce storage space convertible container is provided, comprising: a main body capable of accommodating contents and having a plurality of surfaces, wherein at least one surface has a double structure in which an inner wall and an outer wall overlap; an outer panel formed on a part of the outer wall, wherein the upper edge is bounded by a first fold line and the remaining edge is separated from the outer wall by a cutting line; and an inner panel formed on a part of the inner wall, wherein the outer panel is pulled outward from the outer wall through a space formed by lifting the outer panel based on the first fold line to form the outer surface of the sauce storage space, and wherein, when the inner panel is pulled outward from the outer wall, the outer panel is inserted into the space formed by the inner panel to form the inner surface of the sauce storage space.

[0009] The above-mentioned outer panel is formed into a first area, a second area, and a third area in a downward direction from the first fold line, and the boundary line between the first area and the second area, and the boundary line between the second area and the third area, may each be formed into a second fold line and a third fold line.

[0010] The above inner panel may be composed of a fifth region formed in the same shape as the first region at a position corresponding to the first region, and a fourth region and a sixth region formed in contact with each of the two edges of the fifth region. Effects of the invention

[0011] According to the present invention, since a sauce storage space can be formed using only a paper folding structure already formed in the container body without adding separate parts, no additional manufacturing costs are incurred, and waste can be reduced as there is no need to use a separate sauce container.

[0012] In addition, when the sauce storage space is not in use, the double structure folds flat so as not to detract from the container's appearance, thus maintaining aesthetics; furthermore, it offers excellent convenience as the user can quickly create the sauce storage space with a simple operation when needed.

[0013] In addition, since the extent to which the sauce storage space protrudes outside the container is limited by the protrusion formed on the lower side wall of the inner wall panel, the structural stability of the sauce storage space is ensured, thereby preventing the sauce from overflowing or the storage space from being excessively deformed.

Similar reference numerals in the drawings refer to the same or similar functions across various aspects.

[0016] Hereinafter, in order to enable a person skilled in the art to easily implement the present invention, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

[0017] FIG. 1 is a drawing showing the structure of a sauce storage space convertible container according to one embodiment of the present invention.

[0018] FIG. 1 (a) shows the external shape of a sauce storage space convertible container according to one embodiment, and FIG. 1 (b) shows the internal structure of a sauce storage space convertible container according to one embodiment.

[0019] Referring to FIG. 1, the container (100) can be formed in the same shape as a conventional container (100) that can be unfolded flat for storage when not in use and assembled to convert into a container with a closed bottom surface and an open top surface when in use. The container (100) can be formed entirely of paper, but is not limited thereto.

[0020] The main body (110) of the container (100) is composed of a bottom surface and a plurality of sides, and at least one of the plurality of sides is composed of a double structure.

[0021] The term "double structure" means that at least part or all of one side is formed of a double panel or double paper that overlaps each other. According to one embodiment, at least one side can be folded at the top of the main body (110) so that the folded part extends into the inner surface of the main body (110), thereby forming a double structure.

[0022] Hereinafter, for convenience of explanation, regarding the surface formed with a double structure, the part forming the outer surface of the main body (110) will be referred to as the outer wall, and the part forming the inner surface of the main body (110) will be referred to as the inner wall.

[0023] Hereinafter, the external structure of the container (100) will be described with reference to (a) of FIG. 1.

[0024] According to one embodiment, an outer panel (120) is formed on at least a portion of the outer wall. The outer panel (120) corresponds to a portion of the outer wall. The outer panel (120) is composed of a first area (121), a second area (122), and a third area (123), and is formed integrally with the outer wall as a portion of the outer wall that has been cut out, and can form a flat plane in the form of a portion of the outer wall when storing the container (100).

[0025] The upper edge of the first region (121) is formed parallel to the upper edge of the main body (110) and is formed as a first fold line (S1). In this specification, the term “fold line” refers to a line that is formed to be thinner than other regions or has incisions formed at regular intervals along the line so that it can be easily folded along the line. Additionally, the term “cut line” refers to a line separated between adjacent regions.

[0026] The first region (121) may preferably be formed in an inverted trapezoidal shape, with its width narrowing from the top edge toward the bottom. The bottom edge of the first region (121) is formed parallel to the top edge, and the bottom edge is also formed as a second fold line (S2). The second fold line (S2) serves as the boundary between the first region (121) and the second region (122). The second region (122) extends a certain length from the second fold line (S2) toward the bottom of the main body (110) and may be formed in an inverted trapezoidal shape similar to the first region (121). The bottom edge of the second region (122) is formed parallel to the second fold line (S2) and is formed as a third fold line (S3).

[0027] The third fold line (S3) becomes the upper edge of the third region (123). The third region (123) is formed in a trapezoidal shape, with its width gradually increasing from the third fold line (S3) toward the bottom of the main body (110). The lower edge of the third region (123) is parallel to the third fold line (S3) and is formed as a cutting line.

[0028] The inverted trapezoidal shape including the first region (121) and the second region (122) can be formed in a symmetrical shape with respect to the trapezoidal shape formed by the third region (123).

[0029] The first to third regions (123) are formed in a mutually separated form through the outer wall and the cutting line, except for the first fold line (S1) portion.

[0030] Meanwhile, a first hole (H1) may be formed with a certain width from the bottom edge of the third area (123) toward the bottom of the main body (110). The first hole (H1) is formed in a shape where the outer panel (120) is pierced, and is formed to make it easier for a user to lift the outer panel (120) by partially inserting a finger into the first hole (H1) when using it.

[0031] Hereinafter, the internal structure of the container (100) will be described with reference to (b) of FIG. 1.

[0032] An inner panel (130) is formed on at least a portion of the inner wall of the main body (110). The inner panel (130) corresponds to a portion of the inner wall.

[0033] The inner panel (130) is composed of a fourth area (131), a fifth area (132), and a sixth area (133), and is formed integrally with the inner wall as a part of the inner wall that is cut out, and can be formed in a shape that forms part of the inner wall when storing the container (100).

[0034] The fifth region (132) is formed in an inverted trapezoidal shape and is formed in the same shape as the second region (122) of the outer panel (120). Additionally, the fifth region (132) is formed in the same location where the second region (122) is formed. The upper edge of the fifth region (132) is formed as a cutting line that separates it from the inner wall, and a second hole (H) may be formed from the upper edge toward the lower direction of the fifth region (132) to allow the user to insert a finger to facilitate operation during use. The second hole (H2) is formed in a shape where the inner panel (130) is cut. The lower edge of the fifth region (132) is formed parallel to the upper edge and is formed as a fifth fold line (S5).

[0035] The fourth region (131) and the sixth region (133) are respectively connected to both sides of the fifth region (132).

[0036] The fourth region (131) and the sixth region (133) are each formed in the shape of a triangle, with one side in contact with each of the two edges of the fifth region (132). The contacting portion is formed by a fold line (S4, S6). Specifically, the first side of the triangle forming the fourth region (131) and the sixth region (133) respectively contacts each of the two edges of the fifth region (132), and the second side extends from one end of the first side in an oblique direction toward the bottom of the main body (110), away from the fifth region (132). Additionally, the third side is formed in a shape connecting the end of the second side and the other end of the first side. The third side may extend from the end of the second side in an oblique direction toward the bottom of the main body (110), while moving closer to the two edges of the fifth region (132).

[0037] A rounded locking portion (G) may be formed in the area where the second side and the third side meet, and in the area where the third side and the first side meet. The locking portion (G) is also a part formed integrally with the fourth area (131) and the sixth area (133). Due to the formation of the locking portion (G), a ledge protruding outward from the fourth area (131) and the sixth area (133) may be formed on the first side. Additionally, the area where the third side and the first side meet is also formed in a shape that protrudes outward from the fourth area (131) and the sixth area (133).

[0038] As described below, the above-mentioned catch (G) performs the function of a stopper that prevents the inner panel (130) from completely moving out of the outer wall during the process of pushing the inner panel (130) out of the outer wall.

[0039] Meanwhile, the remaining two sides of each of the fourth region (131) and the sixth region (133) are bordered by an inner wall and a cutting line. Additionally, in the region that includes all of the fourth to sixth regions (131 to 133), the parts meeting the inner wall are all bordered by cutting lines, except for the fifth folding line (S5).

[0040] Hereinafter, with reference to FIGS. 2 to 5, a method of using a container according to one embodiment of the present invention will be described.

[0041] Referring to FIG. 2, the user lifts the outer panel (120) of the outer wall (first to third areas (121 to 123)).

[0042] After that, as shown in FIG. 3, the fifth region (132) of the inner wall is pushed out of the outer wall. The fifth region (132) is folded relative to the inner wall by the fifth fold line (S5) and pushed out of the outer wall through the gap where the outer panel (120) is lifted. In addition, by the fourth and sixth fold lines (S4, S6), the fourth region (131) and the sixth region (133) are also pulled out of the outer wall at a certain angle with respect to the fifth region (132).

[0043] At this time, there is a catch (G), and since the length of the part where the catch (G) is formed is greater than the length of both sides of the area where the fifth area (132) is pushed out (the length of both edges of the fifth area (132)), the fourth area (131) and the sixth area (133) are not pulled out completely outside the outer wall and are caught. That is, the range of movement of the fourth area (131) and the sixth area (133) is limited. The form in which the fourth to sixth areas (131~133) are pulled out completely outside the outer wall is as shown in FIG. 4. Accordingly, the inner panel (130) forms the outer surface of the sauce storage space.

[0044] Next, as illustrated in FIG. 5, the lifted outer panel (120) is pushed into the space formed by the fourth to sixth regions (131 to 133). Naturally, the first region (121), the second region (122), and the third region (123) are folded at a certain angle relative to each other by the second fold line (S2) and the third fold line (S3), so that the first region (121) and the third region (123) face each other, and the fourth region (131) and the sixth region (133) face each other. That is, a complete sauce storage space is created in which the second region (122) forms the bottom surface and the first region (121), the fourth region (131), the third region (123), and the sixth region (133) form the sides.

[0045] Meanwhile, although only one pair of outer panels (120) and inner panels (130) has been described above, multiple pairs of outer panels (120) and inner panels (130) may be formed within the container (100).

[0046] The foregoing description of the present invention is for illustrative purposes only, and those skilled in the art will understand that other specific forms can be easily modified without altering the technical concept or essential features of the present invention. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. For example, each component described as a single unit may be implemented in a distributed manner, and components described as distributed may likewise be implemented in a combined form.

[0047] The scope of the present invention is defined by the claims for utility models set forth below, and all modifications or variations derived from the meaning and scope of the claims for utility models and their equivalents should be interpreted as being included within the scope of the present invention.
