ABSTRACT:
A paper container with multiple compartments partitioned by walls in different heights, which is formed from a paper board of adequate thickness cut into a predetermined pattern. The paper board is made of paper of pure fibers and additives, laminated to adequate thickness and coated with polyethylene to meet the FDA regulations. The paper board is further formed with a middle opening and embossed with several separate folding lines to define several bottom sections located around the middle opening, partitioning wall sections adjoining the bottom sections, front, rear and lateral wall sections also adjoining the bottom sections, each two partitioning wall sections adjoin each other at one of the folding lines while the front, rear and lateral wall sections are free from connection with other wall sections of the paper board and adjoin several top edge strip sections. Three folding lines are formed at each corner contained by the wall sections, making the corner form two adjacent equiangular triangle-shaped corner connection sections, whereby each two adjacent corner connection sections and the top edge strip sections can be folded and overlapped and heat-sealed on adjacent front and lateral wall sections to form the paper container for more suitably containing various foods with different shapes and volumes.
