Description
BACKGROUND OF THE PRESENT INVENTION
[0001] 1. Field of Invention
[0002] The present invention relates to a foldable bag, and more
particular to a foldable bag which can be used as a shopping bag
that is capable of folding up to reduce its size when it is not
used for ease of carrying and reused.
[0003] 2. Description of Related Arts
[0004] In 1870, an American, Margaret Knight, invented a kind of
Kraft paper shopping bag with flat bottom. Before that, people
generally used paper to wrap or a kind of cloth made bag for
shopping instead of paper bag. After Margaret Knight designed such
auto-foldable Kraft paper bag with flat bottom, the automate
manufacturing machine for Kraft paper bag production, and founded
the East Paper Bag Corporation, the flat bottom Kraft paper
shopping bag is widely used by people for shopping. Thereafter, due
to the invention of the plastic bag, this kind of Kraft paper
shopping bag is gradually replaced with by plastic bag. However,
due to the recent promotion of environmental protection, the
plastic bag becomes unpopular due to its difficulty in
decomposition after used. Hence, the Kraft paper shopping bag is
adopted again to replace the plastic bag, especially for shopping
goods like breads, cakes and beverages such as coffee.
[0005] Although the Kraft paper shopping bag will not cause
environmental pollution, the Kraft paper shopping bag still has a
lot of shortcomings. Since the Kraft paper shopping bag is
generally thin and limited in designable shape, the Kraft paper
shopping bag is not that durable and reusable after repeatedly
folding up for storage. Therefore, it is not portable and may not
be repeatedly used again and again. In addition, the Kraft paper
shopping bag is made from a raw material produced from the woods
and trees, so that another environmental problem arises according
to the increased the amount of the Kraft paper shopping bags being
used. Hence, it is a common desire to have a foldable bag to be
used as, for example, shopping bag, that is convenient to carry
along, ease for storage, reusable repeatedly, and good looking in
order to overcome the shortcomings of the prior arts.
SUMMARY OF THE PRESENT INVENTION
[0006] An object of the present invention is to provide a foldable
bag to overcome the shortcomings of the conventional paper bag,
such as not durable for repeatedly used and folding up for storage,
resulting in the increased amount of the paper bags being used.
[0007] Another object of the present invention is to provide a
foldable bag which is convenient in carrying along and can be used
repeatedly.
[0008] Another object of the present invention is to provide a
