[0001] Not applicable.
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
[0002] Not applicable.
NAMES OF PARTIES TO A JOINT RESEARCH AGREEMENT
[0003] Not applicable.
REFERENCE TO AN APPENDIX SUBMITTED ON COMPACT DISC
[0004] Not applicable.
BACKGROUND OF THE INVENTION
[0005] 1. Field of the Invention
[0006] The present invention relates generally to a self-standing
bag, and more particularly to an innovative self-standing bag,
which allows foldable flanges to be assembled at a top of two side
walls of the main body.
[0007] 2. Description of Related Art Including Information
Disclosed Under 37 CFR 1.97 and 37 CFR 1.98.
[0008] A self-standing bag is widely used to as refill packages for
liquid products (e.g. laundry detergent, softener), or powder or
granule products (e.g. detergent, feed).
[0009] A conventional self-standing bag is depicted in FIG. 1,
wherein the bottom 03 of the self-standing bag 02 can be expanded
physically into a bigger area, and the top 04 can be compressed in
a flat pattern
[0010] However, there are shortcomings observed during actual
applications.
[0011] First, as regards the stability of arrangement, the side
wall 05 is tilted when the conventional self-standing bag 02 is
expanded by some objects, so the bottom wall of the self-standing
bag 02 will be stretched into an arced shape. In such a case, only
two opposite corners of the bottom 03 of the self-standing bag 02
are stably supported, leading to instability of the conventional
self-standing bag. Thus, it is not ideal for the sales in the shops
and arrangement by the users.
[0012] Second, as regards the ads effect, the space available for
advertisement is only limited to the side wall 05 of the
self-standing bag 02, without mentioning the overlapped portion
around the side wall 05, so the commercial effect of the
self-standing bag is not suitable for marketing purposes.
[0013] Thus, to overcome the aforementioned problems of the prior
art, it would be an advancement in the art to provide an improved
structure that can significantly improve efficacy.
[0014] Therefore, the inventor has provided the present invention
of practicability after deliberate design and evaluation based on
years of experience in the production, development and design of
related products.
BRIEF SUMMARY OF THE INVENTION
[0015] Based on the unique present invention, the self-standing bag
allows foldable flanges to be assembled at a top of two side walls,
and the top of these two side walls is separated by a top wall. So,
when the self-standing bag is filled with some objects, the two
side walls can be expanded into a tubular space, and then the
bottom of these two side walls is supported in a flush state,
enabling the self-standing bag to be positioned stably for the
purpose of smooth sales and reliable arrangement.
[0016] Based on the unique present invention, foldable flanges are
assembled at the top of two side walls. The print ads space of the
self-standing bag can be further increased, thus providing a
clearer and wider picture for improved graphical representation and
marketing purpose.
[0017] Although the invention has been explained in relation to its
preferred embodiment, it is to be understood that many other
possible modifications and variations can be made without departing
from the spirit and scope of the invention as hereinafter
claimed.

DETAILED DESCRIPTION OF THE INVENTION
[0025] FIGS. 2-3 depict preferred embodiments of a self-standing
bag of the present invention with a foldable flange. The
embodiments are provided for only explanatory objectives with
respect to the patent claims.
[0026] The self-standing bag A comprises a main bag body 10, which
is available with two corresponding side walls 11 and a bottom wall
12 connected between the bottom of two side walls 11 (shown in FIG.
3).
[0027] The bag A also comprises a top wall 20, which is connected
between the top of two side walls 11 of the main bag body 10 in a
transversely flanged pattern.
[0028] Two foldable flanges 30, 30B are extended from the top of
two side walls 11 of the main bag body 10 to a proper area.
Moreover, an opening 31 is formed between two corresponding sides
of the foldable flanges 30, 30B.
[0029] The corners 32 of the foldable flanges 30, 30B are designed
into rectangular or obtuse (e.g. beveling and rounding) patterns.
FIG. 2 depicts the rounding pattern of the corners 32.
[0030] An object outlet 40 is placed centrally or laterally onto
the top wall 20. Referring to FIGS. 2 and 3, the object outlet 40
is comprised of a protruding screwed pipe 41 and a blind nut 42.
The blind nut 42 can be screwed onto the protruding screwed pipe 41
to seal the object outlet 40. Conversely, the object outlet 40 can
be opened by loosening the blind nut 42.
[0031] Referring to FIG. 4, the foldable flanges 30, 30B can be
additionally provided with a handle hole 50, allowing the user to
lift and carry manually the self-standing bag.
[0032] Referring to FIG. 5, the object outlet 40 of the preferred
embodiment is placed laterally onto the top wall 20B, and the top
wall 20B is set into a downward inclined plane.
[0033] The core design of the self-standing bag A of the present
invention lies in that, foldable flanges 30, 30B are extended from
the top of two side walls 11 of the main bag body 10. As shown in
FIG. 3, the top of two side walls 11 is separated by the top wall
20, rather than two conventional side walls' tops that are
connected in a flat state, so these two side walls 11 of the
present invention can be expanded into a tubular space, and then
the bottom of these two side walls 11 is supported in a flush
state, enabling the self-standing bag to be positioned stably.
Furthermore, with the arrangement of the foldable flanges 30, 30B,
the print ads space of the self-standing bag A can be increased,
allowing for flexible and convenient arrangement of the letters,
patterns and trademarks for marketing purpose.
[0034] Additionally, based on the design that an opening 31 is
formed between two corresponding sides of the foldable flanges 30,
30B, these two foldable flanges 30, 30B are disconnected. After the
users purchase the products packaged by the self-standing bag A,
these two foldable flanges 30, 30B can be folded into a
transversely extension state (in collaboration with FIG. 6), or
folded downwards to be abutted externally against the side wall 11
(in collaboration with FIG. 7), so the object outlet 40 on the top
wall 20 is exposed for ease-of-use. It is thus learnt that these
two foldable flanges 30, 30B can improve the convenience for the
benefit of the users.
