Bag with a safety net
Abstract
Ordinary bags are made of either paper or plastic material. Due
to a puncture of the bag, the point of puncture quickly becomes a
ripping point to further enlarge an originally small opening. The
present invention overcomes this shortcoming of ordinary bags by
using a new material that is produced by adhering a web material
with a base material. The web material would effectively serve as a
safety net to prevent further ripping of the bag once the base
material of the bag is punctured.

Description
FIELD OF THE INVENTION
[0001] The present invention is related to the field of bags. More
specifically, the bag of the present invention is made of a
textural material that enhances both the durability and the
ornamental appeal of the bag.
DESCRIPTION OF THE RELATED ART
[0002] Conventional foldable bags have been in the marketplace for
many years. They are typically shaped as shown in various figures
of U.S. Pat. No. 6,000,849 issued to Keller; U.S. Pat. No.
6,146,618 issued to Keller; U.S. Pat. No. 6,345,912 issued to Ho;
U.S. Pat. No. 6,737,959 issued to Ho; U.S. Pat. No. 6,749,064
issued to Alrey; U.S. Pat. No. 5,836,095 issued to Crowell; U.S.
Pat. No. 6,045,263 issued to Keller; U.S. Pat. No. 5,613,312 issued
to Crowell; U.S. Pat. No. 6,045,263 issued to Keller; U.S. Pat. No.
5,613,312 issued to Crowell; and U.S. Pat. No. 5,441,348 issued to
Valentino. These foldable bags are generally made of paper or
plastic.
[0003] While thick paper sheets are able to withstand acceptable
amount of load and stress, the material strength of paper
deteriorates substantially when used repeatedly, when it becomes
wet, or when it is punctured. As individual fibers making up a
paper sheet becomes wet, they tend to absorb the water in their
surrounding until the amount of absorption reaches a saturation
point. Moisturized or soaked fibers swell up and expand in size.
Due to this fiber expansion, the frictional force holding numerous
fibers together would become weaken as contact surfaces of the
fibers decreased. In addition, each of the individual swelled
fibers also disintegrates and allows the paper sheet to become more
susceptible to tears. Consequently, the durability of a bag made of
paper material greatly deteriorates once it is soaked with liquid
or when it is used in a humid environment.
[0004] Generally, an un-punctured paper bag is highly resistant to
tears due to various types of tear resistant barriers designed into
the bag. However, once a puncture or cut exist on the paper bag,
the paper bag is highly susceptible to tears, hence enlargement of
the puncture or cut. It is often the case that once a layer of a
paper bag is punctured by a foreign object, such as by an object
stored in the bag, the weight of the foreign object tends to travel
downward due to gravitational pull. As the foreign object travels
downward beginning from the point of penetration of the paper bag,
the initially small opening is enlarged because the amount of
gravitational pull is greater than the tear tolerate point of the
paper. As the opening is enlarged, other objects stored therein the
bag would also fall out of the paper bag due to gravitational pull.
Therefore, the paper bag is rendered useless.
[0005] Foldable bags made of plastic materials tend to be very
resistant to deterioration when exposed to liquid or moisture.
However, plastic provides a less rigidity characteristic than
paper. A paper bag can maintain its form and rigidity even used
under higher load than it is designed to withstand. Upon removal of
the load, it is better able to return to its original shape and
condition. Overall, a paper bag when used in dry conditions and
used under loads slightly higher than it is designed to withstand
would not be permanently damaged.
[0006] On the other hand, a plastic bag demonstrates very little
rigidity and when used under a load slightly more than it is
designed to withstand, it would begin to deform. Once any
deformation occurs in a plastic bag material, the deformation
becomes permanent. Upon removal of an object asserting the load,
deformed plastic materials do not return to their pre-deformed
shapes and conditions.
[0007] Furthermore, since plastic has a more uniformed molecular
structure than paper, once there is a small puncture or a cut in
the plastic bag, it requires very little amount of force to rip a
plastic sheet wide open.
[0008] Therefore, both paper bags and plastics bags have serious
shortcomings in that they are incapable to resist tears once they
are punctured or cut.
OBJECT OF THE INVENTION
[0009] An objective of the present invention is to overcome the
above-discussed shortcomings of bags that are conventionally made
of paper material and plastic material.
[0010] Another object of the present invention is to manufacture a
new material by adding a web material to a plastic material, a
paper material and a foil material, etc.
[0011] A third object of the present invention is to manufacture
bags that are able to withstand higher loads and higher stresses
than conventional bags.
[0012] A fourth object of the present invention is to make bags
that are more resistant to tears once they are penetrated or cut by
an object.
[0013] A fifth object of the present invention is to manufacture
bags using a new material unknown among conventional bag making
materials.
[0014] A sixth object of the present invention is to provide a
safety net on the bag so as to prevent objects from falling out of
the bag even if the bag is torn or punctured.
[0015] A seventh object of the present invention is to use the new
material as a communication medium to convey seasons of the year,
occasions the bag is suited for and sentiments associated with the
use of the bag.
[0016] Other objects of the present invention will become more
apparent upon review of the explanations given hereinunder.

DETAILED DESCRIPTION
[0026] A new material is manufactured by adhering a web material
onto a base material. The web material may be material formed by
weaving, knitting, pressing, or felting natural or synthetic
fibers; a net, a lace, an allover lace or tulle knitted of either
polyester, nylon, rayon, lurex, metallic wire, yam or a combination
thereof. The manner in which the adhering of the web material and
the base material, and post processing thereof is performed as
shown by way of an example in FIG. 6. As shown, there are 11
manufacturing stages divided into stations 1-11.
[0027] In station 1, a roll of a web material 601 is suitably
installed onto a holding roller 600. The roll of web material is
biased between a stabilizing roller 602 and the holding roller 600
to minimize any other motions so as to ensure and isolate a
rotating motion about the holding roller 600. The roll of web
material 601 is also biased between the holding roller 600 and a
driving roller 608 driven by a motor 604 via a driving shaft 606
and a driving belt 607. As the driving roller 608 frictionally
rotates the roll of web material 601, the roll of web material is
unwrapped and the unwrapped material travels toward a directing
roller 610 in bonding station 4.
[0028] In station 2, a roll of base material 611 is suitably
installed onto a second holding roller 612. Any unwrapped based
material 611 is guided by assisting rollers 614 and 616 to travel
over an adhesive application roller 618 in an adhesive application
station 3. Both the web material 601 and the base material 611 are
fed between a second biasing roller 622, a second stabilizing
roller 620 and a second driving roller 624. The second driving
roller 624 is driven by a second motor 626 via a belt 628, in
slitter station 5. As the web material 601 and the base material
611 traveled through the second biasing roller 622, the second
stabilization roller 620 and the second driving roller 624, they
are pressed by the rollers and held together by adhesives applied
by the application roller 618. A new material is thus formed.
[0029] Depending upon specific applications the new material is
being prepared for, peel and stick materials such as for lace or
ribbon may be added onto the new material by installation rollers
630 in slitter station 5. Even though four rollers are shown to
make up installation rollers 630. The number of actual rollers and
the width of a roller may be altered depending upon specific
needs.
[0030] Stations 6-11 are post processing stations to cut and
prepared the new material for specific applications. Station 6 is a
sheeting cutting station. Station 7 is a BOPP sheets accumulating
station. Station 8 is another bag cuffing station. Station 9 is a
cut sheet accumulating station. Station 10 is a new material based
packaging station. Station 11 is a bag forming station.
[0031] Either of the roll of web material 601 or the base material
611 can be installed onto holding rollers 600 or 612, and vice
versa. It all depends on whether adhesives are to be applied to the
web material 601 or base material 611. In the illustrated example,
the based material 611 is applied with adhesives. As the base
material 611 is a long planar sheet of paper material, plastic
material, foil material, etc., adhesives are applied onto the
entire surface of the base material when coming in contact with the
adhesive application roller 618. This would provide an advantageous
effect in that a coding is being uniformly applied to the entire
surface of the base material. This coding may produce a shade of
sheen, a color scheme, an insulating layer, a reinforcement layer,
a combination thereof, or other characteristics desirable for the
application of the new material.
[0032] Alternatively, if the roll of web material 601 is installed
onto the holding roller 612, adhesives will be applied only to the
surface contact side of the web material formed by weaving,
knitting, pressing, or felting natural or synthetic fibers, lace,
tulle, allover lace, net, etc. This would provide an advantageous
effect in that since a web material contains many devoids thus it
would have much less contact surface area than a planar sheet of
base material. Consequently, less adhesive is being used.
Therefore, applying adhesives to the web material is an economical
alternative of applying adhesives to the base material.
[0033] FIG. 7 illustrates a representative cross-sectional view of
an adhesive 702 being sandwiched in-between web material 700 and
base material 704. It should be noted that the thickness of the
adhesive 702, web material 700 and base material 704 may not be the
same. How much difference in thickness between these materials
depend upon specific web material, base material and adhesive that
are being used.
[0034] New materials successfully made by adhering web materials
with base materials are shown by way of examples in FIGS. 8, 9, 10
and 11. As shown in FIG. 8, a green, white and red web material is
adhered to a white base material. This overall color scheme and
pattern configuration is communicative of the Christmas season.
Thus a bag made of this new material can be fashionably used during
the Christmas season.
[0035] FIG. 9 is shown a brown and rice color web material being
adhered to a pink base material. As pink is typically associated as
a feminine color, this new material is communicative that the user
of a bag made of this new material is either a female or the
content stored therein the bag is designated for a female
recipient.
[0036] FIG. 10 is shown a blue web-material with leave and web
patterns being adhered onto a white base material. Given that web
material with leaves are preferred by females yet blue is a
generally a masculine associated color, this color scheme and web
pattern communicates that this new material may be used by either
gender.
[0037] FIG. 11 is shown a white floral web material being adhered
onto a deep maroon base material. As both the floral arrangement
and the deep maroon color are more preferred by females. The use of
this material would be communicative that any contents encompassed
therein would be designated for a female recipient.
[0038] To make a foldable bag 500 as that shown in FIG. 5, the
process starts from establishing a pattern on a piece of material
as shown by way of an example in FIG. 1. As clearly shown, there
are three different types of dash-lines, one type is composed of
only a series of dots 114, another type is composed of a series of
dashes and dots 112 and yet another type is composed of a series of
long dashes 113. These three types of dash-lines signify a
difference in folding directions. If a series of dots of dash lines
signifies that portions parallel to the dash lines are to be folded
into the paper of FIG. 1, then the series of dash lines and dots
signifies that portions parallel to the dash lines and dots are to
be folded out of the paper of FIG. 1. For our example, dash line
114 signifies folding both portions parallel to the dash line into
the paper FIG. 1 and dash line 112 signifies folding both portions
parallel to the dash line out of the paper of FIG. 1.
[0039] The series of long dash lines signifies that due to multiple
layers of folding, portions parallel to this series of long dash
lines may fold either into or out of the paper FIG. 1.
[0040] The numerous dash lines nicely divide the rectangular shape
new material 100 into different zones. As shown, there are a header
zone 102, a body zone 104, a footer zone 106, a first flat-side
zone 118, a second flat-side zone 120, a first folding zone 108, a
second folding zone 110, and a tap zone 122.
[0041] Located on each of the first flat-side zone 118 and the
second flat-side zone 120 are four string holes 116, 124, 126 and
128. String holes 116 and 124 are complementary pairs of string
holes 126 and 128, whereupon the folding of the header zone 102 to
be flush with the body zone 104, holes 116 and 124 on the header
zone 102 would correspondingly meet holes 126 and 128 on the body
zone 104.
[0042] Exact and predetermined placement of string-holes 116, 124,
126 and 128 contributes to the overall durability of the bag under
different usage conditions. For the horizontal placement of these
holes, in a situation where the load is of the same foot print as
that of the bag, thus the load placed on the bag 500 can be
uniformly shared across the full width of the bag, then placement
of these holes should observe the characteristics of d3=d4=d1.
[0043] In a situation where the load is not of the same foot print
as that of the bag and the load tends to concentrate in the
mid-width portion of the bag, then placement of these holes should
observe the characteristics d3<d1, d4<d1 and d3=d4.
[0044] In a situation where the load is not of the same foot print
as that of the bag and the load tends to concentrate on one side of
the bag, then placement of these holes should observe the
characteristics d1<d3, d1<d4 and d3=d4.
[0045] These string-holes may be individually created on the header
zone and the body zone. They can also be created after the header
zone is folded into the body zone. They can further be created
after a reinforcement member 400 is adhered in-between the header
zone and the body zone.
[0046] As bags are manufactured in different sizes; generally, the
larger is the size of the bag, the more important it is to
correctly choose the placement of the string-holes. However,
depending on the size and weight of the load, these horizontal
string-hole placement considerations are also applicable to smaller
size bags.
[0047] Vertical placement of string-holes 1 16, 124, 126 and 128
should observe characteristics that d2=d6 and d2>d5. This is to
compensate for the fact that while the material at the rim of these
holes experience the most amount of compressive force, the edge of
the material above these holes experience the most amount of
tensile force, due to the load. In addition to the concerns over
the placement of the ring-holes, a reinforcement member 400 should
also be added in-between the header zone 102 and the body zone 104.
This reinforcement member helps regions surrounding string-holes
116, 124, 126 and 128 to withstand the compressive force and
tensile force so as to prevent material 100 from breaking down and
cause a tear to occur beginning from around the rims of the
string-holes. An eyelet may also be added to each string-hole as a
further tear prevention device. This reinforcement member 400 also
helps to redistribute the load evenly across the width of the bag.
To redistribute the load across the full width of the bag, the
width of the reinforcement member 400 should be the full width of
the bag. However, as shown in FIG. 4, the reinforcement member 400
is shown by way of an example to be shorter than the full width of
the bag. The bag shown in FIG. 4 thus has a lighter load capacity
than a bag where the reinforcement member is the full width of the
bag.
[0048] It is preferred that the reinforcement member 400 be adhered
in-between the header zone 102 and the body zone 104, this would
further ensure that all surfaces coming into contact with the
reinforcement member 400 evenly share the load and evenly
distribute sharing of the load to other zones of the bag.
[0049] FIG. 2 illustrates a bottom view of material 100 that is
being folded along various fold lines. Points 202, 204, 206, 208,
210 and 212 respectively correspond to fold lines 112, 114, 144,
146, 148 and 150. An outer surface of the tap 122 is adhered to an
inner surface of the first flat-side zone 118. The larger is the
size of the tap 122, the more surface contact will there be between
the tap 122 and the first flat-side zone 118. The stronger will
also be the integrity of the bag. Given that the new material 100
has a web side, the devoid spaces formed by the web patterns
effectively create an adhesive retaining pool, so that greater
amount of adhesives may be used to provide a stronger hold of two
contacting surfaces. This retaining pool feature also contributes
to the making of a stronger bag.
[0050] FIG. 3 provides another bottom view showing the footer zone
being folded along various long dash lines to form a closure end.
Specifically, the closure end is made by folding a first bottom
edge of the first folding zone 110 and a second bottom edge of the
second folding zone 108 toward each other so that the first and
second bottom edges are substantially parallel. Then there is
further folding of a third bottom edge of the first flat-side zone
118 and a fourth bottom edge of the second flat-side zone 120
toward each other to form a first closure tab and a second closure
tab in a way that the third and fourth bottom edges are
substantially parallel and overlapping each other. The closure end
is finalized by adhering the first closure tab to the second
closure tab wherein the web material on one of the first closure
tab and the second closure tab form a retaining wall to retain a
pool of adhesives when the first closure tab is adhered to the
second closure tab at the overlapping surfaces.
[0051] Again, due to the presence of web patterns to retain a
greater amount of adhesive material, the closure end of the present
invention is much stronger than conventional closure ends without
