Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This patent application claims priority under 35 U.S.C. §119 to Korean Patent Application No. 10-2015-0160520, filed on Nov. 16, 2015, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety.

TECHNICAL FIELD

Embodiments of the present disclosure concern disposable food packaging, and more specifically, to disposable paper containers that are easily folded or unfolded for convenient use in various events required to feed a good number of people.

DISCUSSION OF RELATED ART

Disposable food packaging comprises disposable items often found in fast food restaurants, takeout restaurants and kiosks, and catering establishments. Food serving items for picnics and parties is very similar. Typical disposable food service products are plates, bowls, cups, utensils, doilies and tray papers. These products can be made from a number of materials including plastics, paper, bio-resins and bamboo.
Conventional types of packaging of fast food and take-out tout am necessary for the customer but involves a significant amount of material that ends up in landfill, recycling, composting, or litter.
Conventional disposable food containers, as manufactured of plastics or other harmful chemicals, cause significant environmental concerns. To address such environmental issues, paper-based food packages have been introduced. However, such conventional paper containers have a fixed shape or volume and fail to respond to various customer needs.

Referring to FIG. 12, the disposable paper container 200 includes a bottom part 210 and a side part 220.
The side part 220 is folded along dashed lines to be erected extending from the bottom part 210, forming a space C.
A process for forming the disposable paper container 200 is described below with reference to FIGS. 13 to 20.
FIGS. 13 to 20 are views illustrating a process for forming a disposable paper container as shown in FIG. 11, using a piece of paper cut into a shape as shown in FIG. 12, according to an embodiment of the present disclosure.
Prepared is a piece of paper cut into a shape as shown in FIG. 12.
To form the first sub-side part 220 a, the first connecting sub-side part 220 e, and the fourth connecting sub-side part 220 h, the piece of paper is folded along a dashed line a′ in a direction as denoted with an arrow as shown in FIG. 13.
Then, two opposite corners of the piece of paper are folded along dashed lines b′ in directions as denoted with arrows as shown in FIG. 14.
The folded part of the piece of paper is folded along a dashed line c′ in a direction as denoted with an arrow as shown in FIG. 15.
To then form the third sub-side part 220 c, the second connecting sub-side part 220 f, and the third connecting sub-side part 220 g, the piece of paper is folded along a dashed line d′ in a direction as denoted with an arrow of FIG. 17, resulting in the piece of paper being in a shape as shown in FIG. 17.
Two opposite corners of the piece of paper are folded along dashed lines e′ it directions as denoted with arrows of FIG. 18.
The folded part of the piece of paper is folded along a dashed line f′ in a direction as denoted with an arrow of FIG. 19.
Then, the two opposite folded parts g′ of the piece of paper are pulled and open in directions away from each other, forming a disposable paper container as shown in FIG. 11.
As described above, the first sub-side part 220 a and the third sub-side part 220 c to which the flaps 230 are not attached are folded in such a manner as described above and are then spread out to be erected, thereby allowing the second sub-side part 220 b and the fourth sub-side part 220 d to be erected as well. Resultantly, an internal space C is also formed.
In other words, two opposite parts of the piece of paper, which are positioned at two opposite edges of the bottom part 210, are folded towards each other with respect to the bottom part 210, two opposite corners of each of the folded parts are folded towards the bottom part 210, the two folded parts are then folded away from the bottom part 210 to cover the folded corners, and the resultant folded parts are then pulled in directions away from each other, thereby allowing the side part 220 to erect.
The flaps 230 of the disposable paper container 200 may be used as handles allowing for easier or more comfortable use of the disposable paper container 200.
According to embodiments of the present disclosure, the disposable paper container 100 or the disposable paper container 200 may be formed in various sizes or dimensions to fit their uses and allow for convenient use in, e.g., various events required to feed a good number of people.
According to embodiments of the present disclosure, disposable paper containers may remain in an unfolded, stretched-out position while they are not in use, allowing for easier storage in a reduced volume, and upon use, they may be folded in a way described above to shape a container.
While the inventive concept has been shown and described with reference to exemplary embodiments thereof, it will be apparent to those of ordinary skill in the art that various changes in form and detail may be made thereto without departing from the spirit and scope of the inventive concept as defined by the following claims.
