Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a bag apparatus and method
of making the same, and, in particular, to a new bag and handle
design for enabling a bag made using a paper or paper-like product
to handle greater weight.
[0003] 2. Description of the Related Art
[0004] Paper-based or paper-like bag products are known in the art.
For instance, there are several types of store bags that are
provided by a merchant to help a customer carry purchased
merchandise. One famous example is the "Brown Bag" provided by
Bloomingdale's outlets. Another example is the gift bags that one
might get at a Hallmark store or Bed Bath & Beyond and similar
stores.
[0005] In all of these bags, which are either paper-based or use a
paper-like product, one of the weakest parts of the bag is where
the handle is attached to the frame of the bag. Depending on the
particular structure used by the manufacturer of the bag, if too
much weight is applied or if the bag is held at an awkward angle,
either the bag itself may tear or the handle may become disengaged
from the bag frame. Other manufacturers have attempted to provide
bags that utilize stronger materials such as cloth-based products,
nylons, or other synthetics. However, these designs often greatly
increase the cost of the bag, which must be kept low so that it
makes economic sense for the manufacturer to sell them cheaply or
provide them to customers for free.
[0006] Nylon or cloth-based duffle bags are also known in the art.
However, these bags do not suffer from the problems associated with
paper-based or paper-like bags in that the materials ensure a
relatively strong bag. However, these bags are far more expensive
than bags that use paper-based or paper-like materials and thus are
not suitable for the purpose of providing gifts or being provided
by a merchant after a purchase.
[0007] Thus, in light of the foregoing, there is a need for a new
paper-based or paper-like bag or bag and method for making such bag
in an economical manner that provides a cost-effective bag that is
strong enough to reduce the risk of tearing when carrying
relatively heavy articles.
SUMMARY OF THE INVENTION
[0008] In view of the above discussion, the shortcomings in known
bags are overcome, at least in part, by a bag that comprises a
frame constructed from a paper-based or paper-like product, at
least one handle constructed from a paper-based or paper-like
product and including an engagement portion having a first support
component and a second support component wherein each of the first
support component and a second support component is stitched to a
portion of the frame. Further, a frame support may be included
generally at the location of the portion of the frame where the
engagement portion of the handle is stitched.
[0009] As used herein, the terms "paper-based" and "paper-like"
refer to a material that includes paper, synthetic papers,
plastics, and other materials that generally have the physical
properties of natural paper.
[0010] As an additional feature of the invention, the frame of the
bag may be constructed from a single sheet of material and folded
so as to hide the point of engagement between the frame and the
handle on the inside of the frame. Moreover, the bag may be
additionally folded so as to give the bag the appearance that it is
constructed from more than one material or sheet. Stitching may
also be included to enhance this appearance.
[0011] In an embodiment of the handle, the handle is constructed
from a single sheet and folded over itself such that the engagement
portion of the handle is substantially flat whereas the upper
portion of the handle is pinched. This advantageously increases the
strength of the handle mechanism. The folded portions of the handle
may be stitched and/or glued in place. To further increase the
strength of the handle, a second support component, such as a piece
of fabric may be layered on the first sheet forming the handle and
folded within the first sheet so as to hide its existence.
Stitching and/or an adhesive may be added to hold both the first
sheet and the second support component in place.
[0012] Additional features and advantages of the system and methods
of the invention are described further below.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0021] With reference now to FIGS. 1-6 there will be shown and
described several embodiments of an improved bag and handle
assemble, and method of making the same. The improved bag and
handle assembly advantageously provides increased strength to the
bag and further enables the bag to be constructed such that it
appears that the bag is made from multiple materials or parts.
[0022] With reference to FIG. 1, a perspective view of a first
preferred embodiment of a bag and handle assembly 10 is shown. The
assembly preferably includes a frame 15 having a front and rear
panels 20, 22, two side panels 24, 26, and a bottom panel 28. As
will be discussed further in connection with FIG. 6, the frame 15
is preferably, but not necessarily, formed from a single sheet that
is folded so as to form the front and rear panels 20, 22, two side
panels 24, 26, and a bottom panel 28. Interior space 17 and open
end 19 are created by formation of the front and rear panels 20,
22, two side panels 24, 26, and a bottom panel 28 of the frame
15.
[0023] With further reference to FIG. 1, handle assembly 30 is
fixedly attached to bag frame 15 via stitching 36 (as shown) or an
adhesive (not shown), or any combination thereof. Handle assembly
30 preferably includes a pinched or folded handle 32 in combination
with generally flat engagement portions 34. The construction of the
handle assembly 30, and in particular engagement portions 34 is
described further in connection with FIG. 3. As can be seen from
the arrangement of FIG. 1, the handle assembly 30 is generally
U-shaped and constructed such that engagement portions 34 extend a
substantial way down side panels 20. For both design aesthetics and
to increase the strength of the engagement of handle assembly 30 to
frame 15, stitching 36 extends down the length of engagement
portions 34. In an alternate embodiment, as shown in FIG. 2,
engagement portions 34' does not extend a substantial way down the
bottom of front panel 20.
[0024] It should be understood that although the foregoing
discussion has focused on a single handle assembly 30 engaged with
front panel 20, the bag assembly 10 preferably includes two such
handle assemblies. The discussion with respect to one handle
assembly applies equally to another such handle assembly engage
with rear panel 22. The same is true with respect to support member
40, discussed below.
[0025] As further shown in FIG. 1, support member 40 may optionally
be included to increase the strength of the connection between
frame 15 and the engagement portions 34 of handle assembly 30. In a
preferred embodiment, two support members 40 are positioned on the
inside of front and rear panels at the location of engagement
portions 34, as shown in FIG. 1. Support member 40 need not, buy
may, extend towards bottom panel 28.
[0026] Like the embodiment shown in FIG. 1, the bag assembly 10'
shown in FIG. 2 includes a frame 15' having front and rear panels
20', 22'. A pair of handle assemblies 30' with engagement portions
34' are fixedly attached to front and rear panels 20', 22' via
stitches 36' in the manner described above. An adhesive (not shown)
may be used in combination with the stitches 36'.
[0027] With reference now to FIGS. 3 and 3a-d, the construction of
the handle assembly 300 will be shown and described. FIG. 3 depicts
a laid open view of a portion of Handle assembly 300. Handle
assembly 300 generally includes a grip section 302, which
corresponds to folded handle 32 of FIG. 1, and a pair of engagement
sections 350 (only of one of which is shown in FIG. 3). The section
between the grip section 302 and the engagement sections 350 is
referred to as transition section 352. Like frame 15, the handle
assembly 300 is preferably constructed of a paper-based or
paper-like material. As shown in FIG. 3, handle assembly 300 has a
number of fold lines F1, F2, F3, F4, and F5 that permit the handle
assembly 300 to be folded such that it creates a folded hand grip
and a folded engagement section, which are each reinforced by the
fact that the material is folded upon itself. Handle assembly 300
may also include flap section 354, which would get folded over
engagement section 350 via fold line F6. A preferred manner of
folding the handle assembly 300 will be described further in
connection with FIGS. 3a-3d.
[0028] As further shown in FIG. 3, handle assembly 300 is stitched
for both structural and design purposes. In the example shown, grip
section 302' contains a single stitch S1 generally down the center
of the folded grip section 302'. In the unfolded state, FIG. 3
shows the holes made by the stitching as S1a, S1b, S1c, and S1d.
Similarly, engagement section 350' receives a generally square or
rectangular stitch S2 to reinforce the connection of the handle
assembly 300 to frame 15 (as further shown in FIGS. 1 and 2). In
the unfolded state, this results in stitch holes S2a, S2b, S2c,
S2d, S2e, S2f, and S2g.
[0029] With reference now to FIGS. 3a-3d, there will be shown and
described a method of folding the handle assembly 300 so as to
create a reinforced handle for attaching to bag frame 15. In FIG.
3a, a portion of grip section 302' is shown. Grip section 302'
includes a pair of side flaps (a) and (b) and a pair of main flaps
(c) and (d). As can be seen, side flaps (a) and (b) are folded
inward and over main flaps (c) and (d). With reference to FIG. 3b,
once side flaps (a') and (b') are folded completely over main flaps
(c') and (d'), main flaps (c') and (d') are folded over one another
to create the folded grip section 302'', which can then be
stitched.
[0030] In FIG. 3c, there is shown a portion of engagement section
350'. Engagement section 350' includes side flaps (e) and (f), main
flap (g), and bottom flap (h). Side flaps (e) and (f) are
preferably folded over on another and also over main flap (g), as
shown in FIG. 3d. Further, optional bottom flap (h) is then folded
over side flaps (e) and (f) and main flap (g). It will be
understood that bottom flap (h) is not used when the engagement
portion 350' is intended to extend towards the bottom of bag frame
15 as shown in FIG. 1.
[0031] As shown in FIG. 4, handle assembly 400 may further include
support member 475 placed inside handle assembly 400. Support
member 475 may be constructed of any known material, but is
preferably a thin and flexible material that has relatively strong
elasticity. By way of example, a fabric or synthetic-based woven
material can be both thin and flexible, while maintaining a high
level of resistance to stretching. It is also preferred that
support member 475 span both the grip section 402 and the
engagement section 450, although the support member 475 may be
substantially the same length as the entirety of handle assembly
400. In addition, it is preferred that support member 475 be wide
enough so as to receive at least a portion of the stitching of
handle assembly 400. Support member 475 may also be fixed inside of
handle assembly 400 through use of an adhesive.
[0032] With reference now to FIG. 5, there is shown an alternate
embodiment of the present invention in which bag 500 is constructed
so as to appear to include two distinct materials. As shown in FIG.
5, bag 500 includes a frame 510 that appears to include two
sections 515 and 520. Sections 515 and 520 are separated by
interface 525, which may further include stitching 530 both to
enhance the structural integrity of bag 500 and to further the
design effect. Sections 515 and 520 may be colored so as to further
the effect of making it appear that bag 500 is constructed of two
different materials.
[0033] Structurally, as shown in FIG. 6, bag 600 is constructed
from a single sheet 605--half of which is shown in FIG. 6. Sheet
605 is preferably cut such that includes a generally rectangular
shaped main section 607 having a number of trapezoidal folded
sections 609 at the bottom thereof. The length and width of the
side of main section 607 will determine the final dimensions of the
bag 600. For example, the width of sections A and C determine the
width of the side panel of the bag (see side panel 26 of FIG. 1).
Moreover, the width of section B determines the wide of the front
and rear panels (see front and rear panels 20, 22 of FIG. 1). In
order to form the rectangular box shape of the finished bag 600,
the sheet 605 must be folded. A preferred embodiment of folding the
bag is shown by fold lines F1-F12 of FIG. 6. To form the bag 600,
sheet 605 is preferably first folded at fold line F5 so that
section 620 is folded over section 610 so as to hide support member
640. The folding of section 620 over section 610 also
advantageously increases the strength of the top of the bag and the
portion of the bag to which engagement section 34 (see FIG. 1) is
attached. Next, sheet 605 is folded at fold lines F6 and F7 so as
to form the interface 525 (see FIG. 5), as shown in FIG. 7. FIG. 7
is an exaggerated and enlarged view of the preferred folding
arrangement of sheet 605. In FIG. 7, it can be seen that the
material (Z) of sheet 605 that lies between fold lines F6 and F7
overlaps a portion of support member 640. Moreover, the folding of
fold lines F6 and F7 causes an interface line (see interface 525 in
FIG. 5) to be formed between section 610 and section 615 on the
outside of the bag. On the inside of the bag, section 620, as
discussed previously, is folded at fold line F5 so as to overlap
material (Z) as well as support member 640. Including optional
support member 640, this creates a five-ply of material at the
location where the engagement section of the handle assembly will
be attached. Thus, in addition to making the look of the bag more
desirable, the strength of the bag is also advantageously
increased.
[0034] With reference again to FIG. 6, the sheet 605 is then folded
at fold lines F2, F3, another fold line (not shown) at the leading
edge of section (c). This brings all four sides of bag 600 together
to form the internal space of bag 600. At this point the bottom of
the bag can be formed, by folding sections 609 upon one another. In
a preferred embodiment, flaps 660 and 664 are folded inward. Next,
flap 662 and a mirror image of flap 662 (not shown) are folded one
at a time over flaps 660 and 664 to form the bottom panel of the
bag. A support member may be added to the inside of the bag to
increase the strength of the bag at the bottom. As shown in FIG. 6,
fold lines F1, F4 and F8-F11 are use to fold the bag flat when not
in use.
[0035] With reference now to FIGS. 8a-8h there are shown eight
different examples of bag designs constructed as described above.
In FIGS. 8a-8c and 8f-8g, in particular, there are shown examples
of bag designs wherein a dual faux material design is incorporated
at the bottom of the bag. As described above in connection with
FIGS. 5-7, the dual material look is created by incorporating an
additional pair of fold lines (such as F6 and F7 in FIG. 6) at the
bottom of the bag where the dual material design is desired to be
located. A stitch line may also be included so as to strengthen the
bag and to add to the faux dual material look.
[0036] Thus, while there have been shown and described fundamental
novel features of the invention as applied to the exemplary
embodiments thereof, it will be understood that omissions and
substitutions and changes in the form and details of the disclosed
invention may be made by those skilled in the art without departing
from the spirit of the invention. It is the intention, therefore,
to be limited only as indicated by the scope of the claims appended
hereto.
