A foldable paper box includes an inner panel that has an inner base wall secured to an outer base wall of an outer panel, two first inner sidewalls and two second inner sidewalls connected foldably to the inner base wall to confine a receiving space that is closed by a cover wall of the outer panel. The outer and inner base walls confine therebetween two insert slots adjacent to the first inner sidewalls. The first inner sidewalls are insertable partially into respective insert slots after being folded to extend uprightly from the inner base wall. The second inner sidewalls are inserted partially and non-removably in between the inner and outer base walls and secured to the outer base wall after being folded.

The foldable paper box of claim 1, wherein said inner base wall has an intermediate part secured to said outer base wall, said insert slots being formed between said inner and outer base walls on two opposite sides of said intermediate part. 3. The foldable paper box of claim 1, wherein each of said first inner sidewall has a sidewall inner part connected foldably to and extending uprightly from said inner base wall, first, second and third sidewall fold lines, a first sidewall top part disposed between said first and second sidewall fold lines and connected foldably to said first inner sidewall part through said first sidewall fold line above said inner base wall, a first sidewall outer part that is disposed between said second and third sidewall fold lines in parallel to said first sidewall inner part and that is connected foldably to said first sidewall top part through said second sidewall fold line, and a first sidewall insert part connected foldably to said first sidewall outer part through said third sidewall fold line, said first sidewall insert part being inserted removably into one of said insert slots. 4. The foldable paper box of claim 3, wherein each of said second inner sidewalls has a second sidewall inner part connected foldably to and extending uprightly from said inner base wall, fourth, fifth, and sixth sidewall fold lines, a second sidewall top part disposed between said fourth and fifth sidewall fold lines and connected foldably to said second sidewall inner part through said fourth sidewall fold line above said inner base wall, a second sidewall outer part that is disposed between said fifth and sixth sidewall fold lines in parallel to said second sidewall inner part and that is connected foldably to said second sidewall top part through said fifth sidewall fold line, a connection part that is connected foldably to said sidewall outer part through said sixth sidewall fold line and that is inserted between said outer and inner base walls and secured to a top side of said outer base wall. 5. The foldable paper box of claim 4, wherein said inner panel further has four corner parts each of which is connected foldably to said first sidewall inner part of one of said first inner sidewalls and to said second sidewall inner part of one of said second inner sidewalls and each of which has a diagonal fold line, each of said corner parts being folded along said diagonal fold line and further folded to extend between said first sidewall inner and outer parts of an adjacent one of said first inner sidewalls. 6. The foldable paper box of claim 5, wherein said second inner sidewall further has two tabs connected foldably and respectively to and projecting from two opposite ends of said second sidewall outer part in opposite directions along a line parallel to said fourth to sixth fold lines, said tabs being folded from said second sidewall outer part to extend between said first sidewall inner and outer parts of an adjacent one of said first inner sidewalls. 7. The foldable paper box of claim 6, wherein said outer panel further has a third fold line parallel to said first and second fold lines of said outer panel, and a second outer sidewall connected foldably to said cover wall through said third fold line of said outer panel, said second inner sidewalls being parallel to said first and second fold lines of said outer panel, said first and second outer sidewalls respectively covering said second inner sidewalls when said cover wall is placed over said outer and inner base walls. 8. The foldable paper box of claim 7, further comprising male and female fasteners respectively attached to said second outer sidewall and one of said second inner sidewalls.
