Abstract

The present invention relates to a paper container having an integral partition and a lid. Two cutouts are formed on a cardboard forming the paper container at each position surrounded by a sidewall portion and two pairs of small isosceles triangular folds adjacent to the two partition portions, wherein each left and right sidewall portion is formed on the cardboard. An extension is formed along the cut to form an overlap. The overlaps of the left and right side wall portions are separated from each other along a tangent line between them. The cover with one top and three bends extends from the outer rim of the right wall. The cut portion allows the cut portion to be removed by overlapping the partition portion, the overlapping portion of the small triangle, and the left and right side wall portions, and the overlap portion on the right wall portion overlaps the left wall portion so that the total width of the overlapped side wall portion is Make sure it is the same width as the cover.

Description

Paper container with integral dividers and covers

The present invention relates to an improved paper container having partitions, and more particularly to a paper container having an integral partition and a lid.

Background

1 illustrates a generally available paper container with an integral partition. The container consists of a bottom surface 1a, a partition 2a, a front wall 3a, a rear wall 4a, a side wall 5a, and an overlapping edge 6a. The partition 2a may be disposed parallel to the front wall 3a and the rear wall 4a, or may be inclined with respect to the bottom surface 1a. The partition 2a has a different width and height. The overlapping edge 6a is turned outward and folded on the side wall 5a to be heat sealed. Such paper containers with integral partitions are widely used in the market. The only disadvantage of this type of paper container is that it does not provide an integral cover. A separate cover is needed to protect food and other objects stored in the container from dust and other contaminants. In order to produce the corresponding lid for the container, there is a separate additional cost for cutting the mold for the lid. Of course, this puts the manufacturer in a difficult situation. Generally, the conventional paper container having an integral partition consists of a cubic body. When a cover is provided integrally on the front or rear wall, the cover has two long side edges and takes up a lot of space when in the fully open state. On the other hand, since the two side walls 5a are heat-sealed by the overlapping overlapping edges 6a, it is impossible to form an integral cover on the side walls 5a.

An object of the present invention is to provide a paper container having a partition and a cover formed integrally.

The above objects as well as the technical meaning applied to the present invention in order to achieve the above object will be more understood with reference to the following detailed description of the preferred embodiment of the present invention and the accompanying drawings.

FIG. 5 is an exemplary view showing a state in which a partition crosses the container at an angle in a paper container having an integral partition and a cover formed from the cardboard of FIG. 4. FIG.

In order to achieve the above object, in a paper container having a partition and a cover formed integrally according to the present invention, the paper container is placed at a position surrounded by two pairs of small triangular overlaps adjacent to the left and right sidewalls and the two partitions. The left and right sidewall portions on the cardboard having two cutout portions formed on the cardboard to be formed, an extension extending along the cutout portion to form an overlapping portion, and the overlapping portion of the left and right sidewall portions separated from each other along a tangent between them; And a cover having one upper surface portion and three bent portions extending from an outer edge of the right wall portion, wherein the cut portion is such that the partition portion, the small triangular overlap portion, and the left and right side wall portions overlap each other. Allow the cutout to be removed, and the overlapping portion on the right wall The cover is overlapped with the side wall portion so that the entire width of the overlapped side wall portion is equal to the width of the cover, characterized in that the cover is configured in one piece in the paper container.

Example

Reference is made to FIG. 2 which shows a cardboard in a fully unfolded state in a first embodiment of a paper container with an integral divider and a lid according to the invention. The cardboard has a tangent a through “h” and is placed in a predetermined position so that the partition portion 2 located between the left bottom portion 11, the right bottom portion 12, the left and right bottom portions 11 and 12, The left end wall portion 31 adjacent to the outer end of the left bottom portion 11, the right end wall portion 32 adjacent to the outer end of the right bottom portion 12, and two side portions of the left bottom portion 11. Included between two adjacent left wall portions 41, two right wall portions 42 adjacent to two side portions of the right bottom portion 12, two adjacent short wall portions and side wall portions 31, 41, 32, and 42. Four pairs of large isosceles triangles 51, two adjacent sidewalls and four pairs of small isosceles triangles 52, which are included between the partitions 41, 2 and 42, 2, and the tangent h A cover upper surface 71 having one edge adjacent to the one right wall portion 42 and three other edges of the cover upper surface 71 along The cover 7 is divided into three cover lids 72, which are provided with a long cover. The cuts 6 are formed along each side of the bottoms 11 and 12 surrounded by the side walls 41 and 42 and two pairs of small isosceles triangles 52. The pair of left wall portions 41 adjacent to the small isosceles triangle portion 52 forms a small overlap portion 411. The pair of right wall portions 42 extending along the cut portion 6 form a large overlap 421. The tangent g between the small overlapping portion and the large overlapping portions 411 and 421 is cut to separate the overlapping portions 411 and 421 from each other. In order to form the paper container according to the present invention, first, the cardboard is folded along the tangent a through the lines f on the bottoms 11 and 12, and the partition 2 in the vertical state and the left and right end walls ( 31 and 32 and left and right side wall portions 41 and 42. Next, the large isosceles triangle portion and the small isosceles triangle portions 51 and 52 are folded to press the short wall portions 31 and 32 and the side wall portions 41 and 42, respectively.

Through the cutout 6, the small overlapping portions and the large overlapping portions 411 and 421 protruding from the left and right side wall portions 41 and 42 are moved toward each other. When the partition portion 2 is erected and the small isosceles triangles 52 overlap and are heat sealed to the side wall portions 41 and 42 as shown in FIG. 3, the overlap portion 421 is the left wall portion. It is fixedly attached to 41 to remove the cutout 6 so that the entire width of the overlapping side wall portion of the paper container is equal to the width of the lid upper surface 71. This includes the lid top portion 71 and the three bends 72 so that the lid 7 is formed as an integral lid of the paper container extending from either side wall of the container, thereby preventing external dust or dirt. Effectively preventing material from entering the paper container can be prevented.

2 and 3, a paper container having a partition and a cover formed integrally is only one preferred embodiment according to the present invention. Various changes in form, size and arrangement or corresponding parts of the components instead of the components shown above are defined to the extent that they do not depart from the technical field to which the invention pertains and the appended claims in accordance with the invention. 4 and 5 show a second embodiment according to the invention. In the second embodiment, the paper container is provided with a partition portion 20 crossing the container at an angle to distinguish between two irregularly shaped partitions having bottoms 11 and 12 and two partitions having different sizes. .

According to the paper container according to the present invention, it is possible to effectively prevent external dust or contaminants from entering the paper container.
