Cone-shaped edible container and manufacturing method thereof

1 . A conical edible container comprising:

an outer shell which is edible;

an inner shell which is edible;

an edible first adhesive layer provided between the outer shell and the inner shell, and configured to bond the outer shell and the inner shell; and

an edible second adhesive layer configured to maintain the outer shell and the inner shell in a conical shape,

wherein at least a partial area of the conical edible container has a first sectional structure, in which the inner shell, the edible first adhesive layer, and the outer shell are sequentially stacked in a direction that faces an outer side from an inner side, and a second sectional structure, in which the inner shell, the edible first adhesive layer, the outer shell, the edible second adhesive layer, the inner shell, the edible first adhesive layer, and the outer shell are sequentially stacked, and a third sectional structure, in which the inner shell, the edible first adhesive layer, the outer shell, the edible second adhesive layer, and the outer shell are sequentially stacked, and

wherein the outer shell is larger than the inner shell so that the entire inner shell is superimposed on the outer shell, and

wherein the first sectional structure, the second sectional structure, and the third sectional structure are sequentially arranged along a circumferential direction of the conical edible container, and

wherein the edible second adhesive layer is positioned between the outer shell and the inner shell to reinforce bonding therebetween in the second sectional structure, and the edible second adhesive layer is positioned between overlapping portions of the outer shell to bond the outer shell to itself in the third sectional structure, and

wherein the edible second adhesive layer is configured to maintain the conical shape by counteracting an elasticity of the inner shell, the elasticity of the inner shell being greater than an elasticity of the outer shell.

2 . The conical edible container of claim 1 , wherein the outer shell includes at least one edible material selected from a group consisting of chlorella, green laver, sea staghorns, laver, agar-agar, seaweed, kelp, gulfweed, and fusiformis.

3 . The conical edible container of claim 1 , wherein the edible first adhesive layer and the edible second adhesive layer are formed of an edible material that provides a hardness of 1500 gf or more when being baked.

4 . The conical edible container of claim 3 , wherein the edible material includes at least one of flour paste, rice paste, and sticky rice paste.

5 . The conical edible container of claim 1 , wherein the inner shell is formed of an edible material, a hardness of which decreases when the edible material absorbs moisture, and which provides a hardness of 1500 gf or more when baked.

6 . The conical edible container of claim 5 , wherein the inner shell includes at least one edible material selected from a group consisting of rice, barley, beans, foxtail millet, proso millet, sorghum, flour, and corn.

7 . The conical edible container of claim 1 , wherein an area of a specific length from an apex of the conical edible container has a sectional structure having only the outer shell.

8 . The conical edible container of claim 1 , wherein the outer shell and the inner shell have a shape selected from a circular shape, a rectangular shape, and a fan shape when the outer shell and the inner shell are unfolded.

9 . The conical edible container of claim 8 , wherein the outer shell and the inner shell each comprise a center of weight and the outer shell and the inner shell are bonded to each other by the edible first adhesive layer such that the center of weight of the outer shell and the center of weight of the inner shell substantially coincide with each other, and the outer shell and the inner shell are bonded to each other by the edible second adhesive layer to form the conical shape.

10 . The conical edible container of claim 8 , wherein the outer shell and the inner shell each comprise a center of weight and the outer shell and the inner shell are bonded to each other by the edible first adhesive layer such that the center of weight of the outer shell and the center of weight of the inner shell substantially do not coincide with each other and the outer shell and the inner shell are bonded to each other by the edible second adhesive layer to form the conical shape.

11 . The conical edible container of claim 8 , wherein in a state where the outer shell and the inner shell are bonded to each other by the edible first adhesive layer to form a body sheet, a cutting line is formed from one point of an edge of the outer shell to a central point of the outer shell and the inner shell, and parts located on circumferentially opposite sides of the cutting line are superimposed and bonded to each other so as to form the conical shape.

12 . The conical edible container of claim 1 , wherein in the third sectional structure, the edible second adhesive layer is positioned to radially overlap an end edge of the inner shell and an end edge of the edible first adhesive layer.

13 . The conical edible container of claim 12 , wherein the edible second adhesive layer comprises a grain paste, and wherein a total radial thickness of the third sectional structure is greater than a total radial thickness of the first sectional structure, thereby counteracting the elasticity of the inner shell.

14 . The conical edible container of claim 13 , wherein the edible second adhesive layer is configured such that a bonding force between overlapping portions of the outer shell in the third sectional structure is greater than a bonding force between the inner shell and the outer shell in the first sectional structure.

15 . A method for manufacturing a conical edible container, the method comprising:

(a) preparing the outer shell which is edible and an inner shell which is edible;

(b) bonding the outer shell and the inner shell using an edible first adhesive layer provided between the outer shell and the inner shell;

(c) forming a conical shape by winding the outer shell and the inner shell in a state, in which the outer shell and the inner shell are bonded to each other, by an edible second adhesive layer such that the conical shape is not released, and

wherein at least a partial area of the conical edible container has a first sectional structure, in which the inner shell, the edible first adhesive layer, and the outer shell are sequentially stacked in a direction that faces an outer side from an inner side, and a second sectional structure, in which the inner shell, the edible first adhesive layer, the outer shell, the edible second adhesive layer, the inner shell, the edible first adhesive layer, and the outer shell are sequentially stacked, and a third sectional structure, in which the inner shell, the edible first adhesive layer, the outer shell, the edible second adhesive layer, and the outer shell are sequentially stacked, and

wherein the outer shell is larger than the inner shell so that the entire inner shell is superimposed on the outer shell, and

wherein the first sectional structure, the second sectional structure, and the third sectional structure are sequentially arranged along a circumferential direction of the conical edible container, and

wherein the edible second adhesive layer is positioned between the outer shell and the inner shell to reinforce bonding therebetween in the second sectional structure, and the edible second adhesive layer is positioned between overlapping portions of the outer shell to bond the outer shell to itself in the third sectional structure, and

wherein the edible second adhesive layer is configured to maintain the conical shape by counteracting an elasticity of the inner shell, the elasticity of the inner shell being greater than an elasticity of the outer shell; and

(d) baking the conical shape.
