Abstract

A packaging box is formed of corrugated cardboard, wherein end portions of the packaging box are protruded relative to a middle portion of the packaging box so that the packaging box has a curved shape, and a corrugation direction of the corrugated cardboard is parallel to a longitudinal direction of the packaging box.

First claim

What is claimed is:

1. A packaging box formed of corrugated cardboard, the packaging box comprising:
an upper panel unit comprising a plurality of upper panels;
a lower panel unit comprising a plurality of lower panels;
a side panel unit comprising a plurality of side panels; and
at least one incision unit configured to prevent damage to a boundary of a portion of the packaging box,
wherein the upper panel unit is divided into the upper panels and the lower panel unit is divided into the lower panels such that both end portions of the packaging box are protruded outwardly relative to a middle portion of the packaging box to form a curved shape, and
wherein the at least one incision unit comprises:
a first incision unit formed in a corrugation direction of the corrugated cardboard; and
a second incision unit extending from end portions of the first incision unit and by a creasing line between a first side panel from among the plurality of side panels and at least one panel from among the plurality of upper panels and the plurality of lower panels.

2. The packaging box of claim 1 , further comprising a plurality of panel units configured to be connected to one another, wherein the plurality of panel units comprises:
the side panel unit forming side panels of the packaging box;
the upper panel unit formed at one side of the side panel unit so as to form an upper panel of the packaging box;
the lower panel unit formed at an other side of the side panel unit so as to form a lower panel of the packaging box; and
a connection unit formed on at least one of the side panels and configured to be connected to another one of the side panels.

3. The packaging box of claim 2 , wherein the at least one incision unit further comprises a plurality of incision units provided between the side panel unit and the upper panel unit, and between the side panel unit and the lower panel unit.

4. The packaging box of claim 3 , wherein the plurality of incision units further comprise a plurality of second incision units formed extendedly and inclinedly from both end portions of the first incision unit.

5. The packaging box of claim 2 , wherein each of the upper panel unit and the lower panel unit is divided into a plurality of panels.

6. The packaging box of claim 5 , further comprising a variation unit configured to vary a distance between the plurality of panels of the upper panel unit and a distance between the plurality of panels of the lower panel unit when a curvature of the corrugated cardboard is deformed.

7. The packaging box of claim 6 , wherein the variation unit is configured to vary an angle between two adjacent panels of the plurality of panels of the upper panel unit.

8. The packaging box of claim 6 , wherein the variation unit is configured to vary an angle between two adjacent panels of the plurality of panels of the lower panel unit.

9. The packaging box of claim 5 , wherein the plurality of panels of the upper panel unit and the plurality of panels of the lower panel unit are configured to overlap one another when a curvature of the packaging box is deformed.

10. The packaging box of claim 9 , wherein each of the upper panel unit and the lower panel unit comprises a creasing line and a cutting line that are configured to meet each other when foldedly deformed while having the creasing line as a center.

11. The packaging box of claim 1 , further comprising:
a first box configured to form an upper portion of the packaging box, and a second box detachably provided at a lower side of the first box, and a fixation unit configured to connect the first box and the second box.

12. The packaging box of claim 11 , wherein the fixation unit comprises:
a first fixation hole formed in the first box,
a second fixation hole formed in the second box, and
a fixing member configured to penetrate the first fixation hole and the second fixation hole.

13. The packaging box of claim 11 , further comprising a cushion member configured to be disposed within the second box, wherein the cushion member has a curved shape, and
wherein the second box comprises an assembly unit configured to connect the second box to the cushion member.

14. A packaging box comprising a plurality of panel units formed of corrugated cardboard comprising a pair of cardboards and a corrugating medium providing corrugation in between the pair of cardboards, wherein the plurality of panel units are connected to each other and configured to be assembled by folding,
wherein a part of the plurality of panel units is deformed into a curved shape in which both end portions of the packaging box are protruded outwardly relative to a middle portion of the packaging box,
wherein a corrugation direction of the corrugating medium is parallel to a longitudinal direction of the packaging box,
wherein the plurality of panel units comprise:
a side panel unit comprising a plurality of side panels,
an upper panel unit comprising a plurality of upper panels;
a lower panel unit comprising a plurality of lower panels; and
at least one incision unit formed between the side panel unit and the upper panel unit and between the side panel unit and the lower panel unit in a corrugation direction of the corrugated cardboard, wherein the at least one incision unit comprises:

a first incision unit formed in the corrugation direction of the corrugated cardboard; and
a second incision unit extending from end portions of the first incision unit and by a creasing line between a first side panel from among the plurality of side panels and at least one panel from among the plurality of upper panels and the plurality of lower panels.

15. The packaging box of claim 14 , wherein the plurality of panel units of the corrugated cardboard comprises:
the side panel unit having the plurality of side panels configured to form side panels of the packaging box;
the upper panel unit comprising a plurality of panels dividedly configured to form an upper panel of the packaging box;
the lower panel unit comprising a plurality of panels dividedly configured to form a lower panel of the packaging box; and
a connection unit formed on at least one of the side panels and configured to be connected to another one of the side panels.

16. The packaging box of claim 15 , wherein the second incision unit extends inclinedly from the end portions of the first incision unit.

17. The packaging box of claim 15 , wherein the at least one incision unit further comprises a plurality of incision units provided between the side panel unit and the upper panel unit and between the side panel unit and the lower panel unit.

18. The packaging box of claim 15 , further comprising a variation unit configured to, when a curvature of the corrugated cardboard is deformed, vary a distance in between the plurality of panels of the upper panel unit and a distance in between the plurality of panels of the lower panel unit.

19. The packaging box of claim 18 , wherein the variation unit comprises a first variation unit configured to vary an angle in between two adjacent panels of the plurality of panels of the upper panel unit.

20. The packaging box of claim 18 , wherein the variation unit comprises a second variation unit configured to vary an angle in between two adjacent panels of the plurality of panels of the lower panel unit.
