Abstract

A single-piece packaging plate foldable to form boxes having different sizes is provided for a product having a variable size. The packaging plate has an elongated plate portion, two side plate portions and two wing portions. The elongated plate portion has a plurality of parallel and spaced-apart preformed fold lines. The side plate portions extend outward from two sides of the elongated portion, and have fold lines at the junctures thereof. The two wing portions can be torn or cut out optionally. Each wing portion has a main wing extending from two sides of an area between sixth and seventh fold lines of the elongated plate portion. The packaging plate is foldable along the fold lines to form a unit body-packaging box or a system-packaging box.

Claims

1. A single-piece packaging plate foldable to form boxes having different sizes, comprising:

an elongated plate portion having first and second short sides, and first to tenth parallel fold lines that are disposed serially from said first to second short sides in a spaced-apart relationship, the distances between said first and second fold lines, between said third and fourth fold lines and between said sixth and eighth fold lines being D1, the distances between said second and third fold lines, between said fourth and sixth fold lines, and between said fifth and eighth fold lines being D2, D2 being greater than D1;

two side plate portions projecting respectively from two sides of an area between said second and third fold lines of said elongated plate portion, said elongated plate portion and each of said side plate portions having a fold line (A) at a juncture therebetween, each of said side plate portions having a fold line (B) and a fold line (C) that are spaced apart in parallel from said fold line (A), a distance from said fold line (A) to said fold line (B) being D1, a distance from said fold line (A) to said fold line (C) being substantially equal to a distance from said second fold line to said first short side of said elongated plate portion and a distance from said third fold line to said fifth fold line; and

two wing portions that can be removed optionally from said elongated plate portion, each of said wing portions having a main wing projecting from one side of an area between said sixth and seventh fold lines of said elongated plate portion, said main wing having a length substantially equal to a distance from said seventh fold line to said ninth fold line.

2. The single-piece packaging plate as claimed in claim 1, wherein a distance from said fold line (A) to said fold line (C) is substantially equal to that from said eighth fold line to said second short side.

3. The single-piece packaging plate as claimed in claim 1, wherein each of said wing portions further includes an insert plate extending from a free end of said main wing, and two auxiliary plates extending respectively from two long sides of said main wing.

4. The single-piece packaging plate as claimed in claim 1, wherein the distances between said sixth and seventh fold lines, between said ninth and tenth fold lines, and between said tenth fold line and said second short side are substantially the same.

5. The single-piece packaging plate as claimed in claim 1, wherein each of said side plate portions is substantially rectangular, and includes a main plate section connected to a long side of said elongated plate portion, two first fixing sections respectively connected to two short sides of said main plate section, and a second fixing section connected to a long side of said main plate section, said main plate section and said second fixing section being separated by said fold line (C).

6. The single-piece packaging plate as claimed in claim 5, wherein said elongated plate portion further has a plurality of spaced-apart projecting plates provided at two sides of areas between said first short side and said second fold line of said elongated plate portion, and between said third and fifth fold lines, each of said side plate portions further having a plurality of apertures provided at said fold line (B), in the vicinity of said fold line (C), and at junctures between said main plate section and said first fixing sections.

7. The single-piece packaging plate as claimed in claim 6, wherein said elongated plate portion further has spaced-apart projecting plates that are disposed respectively at two sides of an area between said fifth and sixth fold lines and that can be inserted into respective ones of said apertures provided at said fold lines (B) of said side plate portions, or respective ones of said apertures provided in the vicinity of said fold lines (C) of said side plate portions.

8. The single-piece packaging plate as claimed in claim 1, wherein said elongated plate portion further has two fixing holes provided in each of areas between said first short side and said second fold line and between said third and fourth fold lines, and adapted to fix a handle.

9. The single-piece packaging plate as claimed in claim 8, wherein said elongated plate portion further has an opening disposed between said eighth and said second short side and adapted to permit the handle to extend outwardly.

10. The single-piece packaging plate as claimed in claim 1, wherein said elongated plate portion further has a fixing insert plate extending from said second short side, and an aperture disposed at said second fold line and having substantially the same length as said fixing insert plate.
