Abstract

Provided is a folding packaging cooler box convertible from a box mode to an unfolding mode or vice versa, comprising: a box portion having a bottom portion, sidewall portions and joint portions configured to connect with one another and to form a single plane in the unfolding mode; and a cooling reinforcing portion configured to be inserted to the inside of the box and to form a hexahedron shape together with said box portion when said box portion is converted into the box mode, wherein said cooling reinforcing portion comprises a reinforcing bottom portion configured to form a lower surface and to face the bottom portion of the said box portion upon conversion into the box mode; reinforcing sidewall portions configured to connect with the said reinforcing bottom portion and to face the sidewall portions of said box portion; and reinforcing joint portions configured to join said reinforcing sidewall portions, to be folded to face itself and to be in close contact with the reinforcing sidewall portions, upon conversion into the box mode, and wherein said reinforcing bottom portion, said reinforcing sidewall portions and reinforcing joint portions form a single plane in the unfolding mode.

First claim

What is claimed is:

1. A folding packaging cooler box convertible from a box mode to an unfolding mode or vice versa, comprising:
a box portion having a bottom portion, sidewall portions and joint portions configured to connect with one another and to form a single plane when the cooler box is in the unfolding mode; and
a cooling reinforcing portion configured to be inserted into the inside of the box portion and to form a hexahedron shape together with the box portion when the cooler box portion is in the box mode,
wherein the cooling reinforcing portion comprises:
a reinforcing bottom portion configured to form a lower surface and to face the bottom portion of the box portion when the cooler box is in the box mode;
reinforcing sidewall portions configured to connect with the reinforcing bottom portion and to face the sidewall portions of the box portion; and
reinforcing joint portions configured to join the reinforcing sidewall portions, be folded to face itself, and be in close contact with the reinforcing sidewall portions when the cooler box is in the box mode,

wherein the reinforcing bottom portion, the reinforcing sidewall portions and the reinforcing joint portions form a single plane when the cooler box is in the unfolding mode,
wherein each of the reinforcing joint portions face the inside of each joint portion of the box portion,
while each of the reinforcing joint portions fold to face itself, each of folded joint portions of the box portion can be inserted to the inside of each reinforcing joint portion, and
the reinforcing joint portions each are in close contact with each adjacent reinforcing sidewall portions, as the joint portions are inserted.

2. The packaging cooler box of claim 1 , wherein
the reinforcing bottom portion, the reinforcing sidewall portions, and the reinforcing joint portions form a single rectangular shape.

3. The packaging cooler box of claim 2 , wherein
each of the reinforcing joint portions has a rounded corner.

4. The packaging cooler box of claim 1 , wherein
the packaging cooler box further includes a compartment which forms a refrigerated space when provided in the inside of the cooling reinforcing portion in the box mode, and the cooling reinforcing portion comprises easy adhesive portions so that the compartment can be attached thereto, as the compartment is rolled down.

5. The packaging cooler box of claim 4 , wherein
the compartment comprises an easy adhesive portion at one end, and a mesh portion which can hold a refrigerant.

6. The packaging cooler box of claim 5 , wherein
while the compartment is rolled down, and thereby a refrigerated space is formed inside, the mesh portion is provided at one surface of the compartment facing the refrigerated space so as to keep the refrigerated space at low temperature.
