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.

BACKGROUND OF THE INVENTION 
The present invention relates to a paper container with multiple 
compartments partitioned by walls in different heights. The paper 
container is formed from a paper board of adequate thickness. The paper 
board is cut into a predetermined pattern on which a plurality of folding 
lines are embossed and a middle opening is formed. The folding lines 
define several bottom sections and partitioning wall sections which adjoin 
the bottom sections and have different widths, whereby the paper pattern 
can be folded and heat-sealed through molds to form the paper container 
with multiple compartments partitioned by walls in different heights for 
more suitably containing various foods or articles in different shapes and 
volumes. 
Conventional food containers are mainly made of paper, polymer or plastic, 
wherein the polymer-made container is integrally formed from the foam 
material and the plastic-made container is formed from melted plastic 
molded in a set of upper and lower molds. Both of the polymer and plastic 
made food containers can be formed with several compartments to meet the 
requirements of containing foods. Basically, the advantages of these 
partitioned polymer and plastic made food containers are convenience in 
use and ease of to manufacture. However, such containers are not subject 
to natural decomposition after they are used and discarded, and therefore, 
will cause serious pollution of and detriment to the whole ecological 
environment that will cost the entire society a higher price to protect 
the environment. Therefore, the polymer and plastic made food containers 
are gradually given up by the users. 
The paper container is mainly made from a paper board cut into a 
predetermined pattern with a plurality of folding lines embossed in 
advance which define several sections of the container. The paper board 
can be folded about the pre-embossed folding lines such that wall sections 
and corner sections are formed. Then, the corner sections so formed are 
overlapped and attached to the wall sections to form a container having 
one single compartment. To contain different kinds of solid or liquid 
foods without mixing their different tastes and flavors, several 
partitioning paper cards are disposed inside the container, giving it 
several compartments. Such paper cards are not convenient in use and are 
simple in structure, being movably attached or fixedly adhered to the 
bottom of the container without reinforcement provided at the periphery of 
the container. Therefore, such partitioning walls provide very weak 
supporting strength and are apt to break, and will no doubt cause troubles 
to the user. Moreover, liquid foods contained in the container easily mix 
with one another and lose their original tastes. Although the paper 
container is subject to natural decomposition and the environment 
pollution caused thereby is relatively low, the conventional paper 
container is not so practical in use and would need improvement. 
It is therefore a need to develop a paper container which has secure 
multiple compartments and strengthened edges and can be easily 
manufactured to eliminate the above shortcomings existing in the 
conventional paper container. 
SUMMARY OF THE INVENTION 
It is a primary object of the present invention to provide a paper 
container with multiple compartments partitioned by walls in different 
heights. The paper container is formed from a paper board meeting the FDA 
regulations by cutting the same into a predetermined pattern which is 
formed with a middle opening and embossed with a plurality of separate 
folding lines to define multiple bottom sections, partitioning wall 
sections, front wall sections, rear wall sections, lateral wall sections, 
and top edge strip sections, wherein the bottom sections are located 
around the middle opening and each two adjacent partitioning wall sections 
adjoin each other at a folding line and have a width different from those 
of other pairs of adjacent partitioning wall sections. The front, rear and 
lateral wall sections are free from connection with any other wall 
sections and are connected with top edge strip sections. Three folding 
lines are formed at each corner contained by the adjacent wall sections, 
making the corner form two adjacent equiangular triangle-shaped corner 
connection sections, whereby each two adjacent corner connection sections 
and the adjacent top edge strip sections can be folded, overlapped and 
heat-sealed onto the adjacent front, rear and lateral wall sections 
through molds to form the paper container with multiple compartments 
partitioned by walls in different heights for more suitably and 
conveniently containing different kinds of foods. 
It is a further object of the present invention to provide the above paper 
container, wherein the top edge strip sections are in strip form and 
adjoin the spaced front and lateral wall sections of the bottom sections. 
Each top edge strip section section has a projected end portion extending 
toward the adjacent bottom section and an opposed flat end whereby the top 
edge strip sections can be folded outward and heat-sealed to the adjacent 
front and lateral wall sections to form even and reinforced edges of the 
paper container and thus prevent the edges thereof from breaking in use. 
The structure, features, functions, and other objects of the present 
invention, and the technical means adopted to achieve the present 
invention can be best understood through the following detailed 
description of the preferred embodiment and the accompanying drawings 
wherein:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
The present invention is a paper container 10 which is formed from a paper 
board made of paper of pure fibers and additives being laminated to 
adequate thickness and coated with polyethylene to meet the FDA 
regulations. The paper board is cut to a paper pattern of predetermined 
configuration. The paper pattern of FIG. 1 is also formed with a middle 
opening 19 and a plurality of embossed folding lines a, b, c, and d, 
defining three bottom sections 11, 12 and 13, several partitioning wall 
sections 14 and 14', and front, rear and lateral sidewall sections 15, 15' 
and 16. The partitioning wall sections 14, 14' have different widths, 
whereby the paper pattern can be folded and heat-sealed to form the paper 
container 10 having three compartments separated by the partitioning walls 
in different heights for more suitably containing various foods or 
articles with different shapes and volumes. 
Please now refer to FIG. 1 which shows an unfolded paper pattern for 
forming the paper container 10 of the present invention, wherein the 
folding lines a to d divide the paper pattern into three bottom sections 
11, 12 and 13. The partitioning wall sections 14, 14' and the front, rear 
and lateral sidewall sections 15, 15' and 16 adjoin the bottom sections 
11, 12 and 13 at the folding lines a. Each two adjacent partitioning wall 
sections 14, 14' adjoin each other at the folding line d, whereby the 
adjacent partitioning wall sections 14, 14' can be folded about the 
folding line d to separate the bottom sections 11, 12 and 13 (as shown in 
FIG. 2). The front, rear and lateral sidewall sections 15, 15' and 16 are 
free from connection with other wall sections of the paper pattern. Three 
folding lines b are formed at each corner contained by the front, rear and 
lateral sidewall sections 15, 15' and 16 and the partitioning wall 
sections 14, 14', making the corner form two adjacent equiangular 
triangle-shaped corner connection sections 17, 17', whereby each two 
adjacent corner connection sections 17, 17' can be folded and overlapped 
to form the three compartments 11, 12 and 13 for conveniently containing 
different foods. 
The front and lateral sidewall sections 15, 16 further adjoin top edge 
strip sections 18 at the folding lines c. Each top edge strip section 18 
has a projected end portion 181 extending toward the adjacent bottom 
section and an opposed flat end, whereby, as shown in FIGS. 2 and 3, the 
top edge strip sections 18 can be folded outward about the folding lines c 
so as to be respectively evenly attached to and heat-sealed on the 
adjacent front and lateral sidewall sections 15 and 16 of the bottom 
sections 11, 12 and 13 with the projected end portions 181 flush with and 
attached to the front and lateral sidewall sections 15 and 16 of the 
adjacent bottom section 11 and 12 to form the paper container 10 with 
secure edges. 
Further referring to FIGS. 2 and 3, the partitioning wall sections 14' of 
two bottom sections 11 and 13 can be alternatively designed to have less 
width and the adjacent corner connection sections 17' can be 
correspondingly designed with less height so that when the paper pattern 
is folded and heat-sealed to form the paper container, the same will have 
a partitioning wall 14' with less height, making the upper portions of the 
adjacent compartments 11 and 13 communicate with each other, so that foods 
with relatively small volume, such as dried bean curd, fried chicken, 
snack, etc., or foods with relatively long size, such as chicken leg, 
barbecue brochette, fish, etc., can be conveniently placed in the 
compartments 11, 13. Therefore, different kinds of foods with different 
shapes and sizes can be contained in the compartments together without 
wasting the room thereof. 
According to the above arrangements, the present invention can provide 
paper container having multiple compartments partitioned by walls of which 
the height can be freely designed for more suitably containing different 
kinds foods with different shapes or volumes.
