Abstract
Provided is a shopping bag adopting a unique design structure, so that a user's will to re-use the shopping bag can be strengthened and the shopping bag is easy to be processed. The shopping bag entirely has an elliptical structure and comprises: a central portion on which an object is placed; a peripheral portion which surrounds the central portion and has various cut patterns formed therein; and a pair of handle portions which are symmetrically formed at both sides of the edge of the peripheral portion, wherein the specially designed cut patterns are adopted in order to relieve asymmetrical stress caused by the elliptical structure and stress concentration due to the cut patterns.
Claims5
A shopping bag for storing an object, comprising:
- a central portion on which the object is disposed;
- a peripheral portion configured to surround the central portion;
- and
- a pair of handle portions symmetrically formed at both sides of an edge of the peripheral portion,
- wherein the edge of the peripheral portion has an elliptical shape,
- a plurality of elliptical virtual lines that are not in overlap with each other are provided in the peripheral portion,
- a plurality of cut patterns that are spaced apart from each other are formed on each of the elliptical virtual lines, and although the plurality of elliptical virtual lines have the same center, major axes of the plurality of elliptical virtual lines have different lengths, and minor axes of the plurality of elliptical virtual lines have different lengths,
- wherein a spaced space between the plurality of cut patterns formed on a predetermined elliptical virtual line is not in overlap with that between the plurality of cut patterns formed on an elliptical virtual line adjacent to the predetermined elliptical virtual line,
- the central portion has a circular shape,
- each of a length of the cut pattern and a distance between two adjacent elliptical virtual lines gradually increases in a direction from the center to the edge,
- a distance between two predetermined adjacent elliptical virtual lines in a direction of the major axis is greater than that in a direction of the minor axis, and
- the central portion, the peripheral portion, and the handle portions are formed on one flat material by Thomson processing.
