Abstract

A complementary paper tube adapted to fill a remaining space on a cargo pallet includes sidewall portions, a straight auxiliary tearing line and circular auxiliary tearing lines. The side wall portions are disposed adjacently to each other. The straight auxiliary tearing line surrounds the sidewall portions. The circular auxiliary tearing lines are disposed on the sidewall portions and respectively connected to the straight auxiliary tearing line. A portion of the area surrounded by the circular auxiliary lines is adapted to be torn away, so as to form circular openings. The complementary paper tube is adapted to be torn into an upper tube and a lower tube. In addition, a flat plate adapted to form the complementary paper tube is also mentioned.

First claim

What is claimed is:

1. A complementary paper rectangular tube, adapted to fill a remaining space on a cargo pallet, comprising:
a plurality of side wall portions, disposed adjacently to each other;
at least one straight auxiliary tearing line, surrounding the plurality of side wall portions; and
a plurality of circular auxiliary tearing lines, disposed on the side wall portions and respectively connected to the at least one straight auxiliary tearing line, wherein a portion of an area of each of the plurality of side wall portions is respectively surrounded by the circular auxiliary tearing lines and adapted to be torn away, so as to form a plurality of circular openings, and the complementary paper rectangular tube is adapted to be torn into an upper rectangular tube and a lower rectangular tube through the circular openings and the at least one straight auxiliary tearing line.

2. The complementary paper rectangular tube according to claim 1 , further comprising a plurality of rhombus-shaped openings, respectively located at a plurality of corners of the complementary paper rectangular tube, and the rhombus-shaped openings respectively connected to the at least one straight auxiliary tearing line and the circular auxiliary tearing lines.

3. The complementary paper rectangular tube according to claim 1 , further comprising a pair of cover portions, respectively covering a top portion and a bottom portion of the complementary paper rectangular tube.

4. The complementary paper rectangular tube according to claim 3 , wherein the pair of the cover portions respectively have inserting holes, and at least one of the side wall portions has a plurality of inserting portions disposed corresponding to the inserting holes, the inserting portions are adapted to be inserted into the inserting holes respectively, so as to respectively hold the pair of the cover portions among the side wall portions.

5. The complementary paper rectangular tube according to claim 1 , wherein sizes and structures of the upper rectangular tube and the lower rectangular tube are substantially the same.

6. A flat plate, adapted to form the complementary paper rectangular tube according to claim 1 , the flat plate comprising a plurality of first folding lines, the first folding lines parallel to each other, perpendicular to the at least one straight auxiliary tearing line, and separating out the side wall portions and an adhering portion on the flat plate, wherein the circular auxiliary tearing lines are respectively located between the adjacent first folding lines and separate out the circular openings on the flat plate, the flat plate is adapted to be folded along the first folding lines and one of the side wall portions is adapted to be adhered on the adhering portion, so as to form the complementary paper rectangular tube.

7. The flat plate according to claim 6 , further comprising a plurality of rhombus-shaped auxiliary tearing lines, disposed at intersections of the first folding lines and the straight auxiliary tearing line, and the rhombus-shaped auxiliary tearing lines separating out rhombus-shaped openings on the flat plate.

8. The flat plate according to claim 6 , further comprising a pair of second folding lines, disposed at two opposite sides of one of the side wall portions and perpendicular to the first folding lines, wherein the pair of the second folding lines separate out a pair of cover portions on the flat plate.

9. The flat plate according to claim 8 , further comprising a plurality of third folding lines, respectively perpendicular to the first folding lines, wherein the flat plate has a plurality of inserting portions, foldably embedded on one of the side wall portions through the third folding lines, and the inserting portions are adapted to be folded and inserted into inserting holes.

10. The flat plate according to claim 8 , wherein the at least one straight auxiliary tearing line and the circular auxiliary tearing lines together separate out the upper rectangular tube and the lower rectangular tube on the flat plate.
