Description
BACKGROUND OF THE INVENTION
The present invention relates generally to household products and specifically to a collapsible container with handles and a method of making and using such a container for convenient storage and transportation of said items.
A typical household often encounters the need for temporary storage of garments prior to washing or cleaning. Regardless of the place where laundry or cleaning is done, either at home or in a commercial setting, soiled garments need to be sorted, stored, and eventually transported to a designated place. The present invention can be utilized for garment sorting, storage and transportation. At the same time, the present invention can also be used for other purposes, such as storage or transportation of toys or other objects. Accordingly, its use is not to be limited to storage or transportation of soiled garments.
Numerous devices are known in the art to provide effective storage of soiled garments, for example laundry baskets, conventional hampers, or clothing bags. For example, U.S. Pat. No. 2,625,973 to Weldon et al. teaches a laundry hamper comprising a rectangular frame having upper and lower portions that telescope within one another in a detachable manner. The lower portion includes a base frame, while the upper portion comprises a top frame. A cover is secured by a hinge to the top frame and an outer bag surrounds the rectangular frame. A plurality of small inner bags are provided within the outer bag. U.S. Pat. No. 1,581,888 to Thomas discloses a collapsible receptacle comprising two rectangular wire frames, hingedly secured together, means for holding the frames to form a triangularly shaped structure, and a fabric portion covering the frames and providing an enclosure.
However, all these prior art devices are voluminous in their expanded state, are uneasy to fold or collapse, are still relatively voluminous in their collapsed state, and are difficult to manipulate. The present invention solves the above-mentioned shortcomings and provides a convenient, easy to manipulate, and ergonomic means for storing or transporting garments or other objects.
SUMMARY OF THE INVENTION
The present invention relates generally to household products and specifically to a collapsible container and method of making and using the same.
According to the present invention, the foregoing and other advantages are obtained by providing a collapsible container comprising a plurality of side panels and a floor panel forming an enclosure having an open top. In the preferred embodiment, each side panel comprises a flexible continuous loop frame, a web of material, and an edging material. The edging envelops the frame and is coupled to the periphery of the web. The floor panel is attached to the bottom side of each side panel thus forming the container.
In an alternate embodiment, each side panel is attached to a side panel separator, which in turn is connected to the next adjacent side panel. The floor panel is attached to both the bottom side of each side panel and to the side panel separators, thus providing means for holding articles within the container and for supporting the container in its expanded state.
In accordance with an aspect of the invention, at least one handle member is coupled to opposite side panels at the open top of the container. Alternatively, the handle may be coupled to only one side panel or may be an aperture formed within one or more of the side panels.
In accordance with another aspect of the invention, an optional storage pouch may be coupled to one of the side panels at the open top of the container. The present invention is easily collapsed into a compact state and the pouch allows storage of the container in its collapsed, compact state.
In another alternate embodiment, the collapsible container further comprises a divider panel, the divided panel being attached to diagonally opposite edgings of the side panels. In yet another alternate embodiment, the collapsible container further comprises at least two divider panels, preferably arranged substantially parallel to each other and being coupled to opposite side panels to create at least three separate compartments within the container.
A preferred method of manufacturing the collapsible container includes the steps of attaching each handle member to a side of two opposite webs. The edging is next coupled to each web such that the edging surrounds the perimeter of the web and forms a channel or pocket through which the frame will later be inserted. After the requisite number of side panels has been formed, each side of the floor panel is attached to the bottom side of each side panel. Next, a side of each side panel is connected with a side of an adjacent side panel. The frame for each side panel is inserted through the channel formed by each edging. The ends of each frame member are connected, preferably using a crimped butt connector, to give the collapsible container its ability to freely stand in a rigid, expanded, upright state.
An alternate method of manufacturing the collapsible container includes the steps of attaching each handle member to a side of two opposite webs. Coupling the edging to each web such that the edging surrounds the perimeter of the web and forms a channel or pocket through which the frame will later be inserted. After the requisite number of side panels has been formed, each corner of the floor panel is attached to one end of each side panel separator. Next each side panel is connected with one side of the floor panel and with two adjacent side panel separators. The frame for each side panel is inserted through the channel formed by each edging. The ends of each frame member are connected, preferably using a crimped butt connector, to give the collapsible container its ability to freely stand in a rigid, expanded, upright state.
From the expanded state, the container can be folded and collapsed for storage or transportation. The preferred steps of collapsing the container include grasping opposite corners of the floor panel and biasing one corner toward the other until all side panels are adjacent and overlay each other. The container is now partially collapsed but each side panel is still in an expanded state. Next, the handle members and the floor panel are inserted in between any two of the adjacent overlaying side panels. By rotating two opposite corners of the flattened, overlaying side panels in opposite directions while biasing the two corners toward each other, the structure will form three overlaying circular loops folded adjacently. Finally, the three overlaying loops are placed into the storage pouch. The pouch prevents the container from springing back into its fully expanded condition.

are connected to one another to form a substantially rectangular container having an open top
16
.
Referring to
FIGS. 1 and 2
and as seen in detail in
FIG. 6A
, each side panel
20
further comprises a frame
22
, a web
24
, and an edging
26
. The frame
22
is flexible, preferably formed from a sufficiently stiff yet resilient, material such as spring steel wire or plastic, and is contained within the channel or pocket
25
formed by the edging
26
. The frame
22
forms a continuous loop. Preferably, the frame
22
has a rectangular cross-section, but a material with a different geometric cross-section can be used. The web
24
is a flexible foldable material, such as nylon cloth or nylon mesh, but can be any suitably flexible material. The nylon, or other flexible material, may be solid or perforated. The perimeter of the web
24
is stitched to the edging
26
such that the edging
26
forms a pocket
25
about the periphery of the web
24
. The edging
26
is a foldable, but stretch-resistant material capable of housing the frame
22
within its pocket
25
. The edging
26
has two ends
27
and
29
.
A seam cover
28
, also made out of a foldable stretch-resistant material, may be provided to cover the ends
27
and
29
of the edging
26
, thereby protecting the frame
22
from escaping out of the edging
26
. As shown in
FIG. 1
, the seam cover
28
is also stitched to the web
24
.
As shown in
FIG. 7
, the floor panel
50
is also a foldable web of material and has a generally rectangular shape. The floor panel
50
has four corner sections
52

50
provides means for holding the garments or other objects (not shown) within the container
10
and for supporting the container
10
in its expanded state.
Referring now to
FIGS. 5-8
, the preferred embodiment of the collapsible container
10
is shown. The preferred embodiment includes side panel separators
40
located between each side panel
20
. However, it should be noted that the side panel separators
40
are not required to practice the present invention. The side panel separators
40
are shown to be substantially longitudinal, each including an end
42
attached preferably by means of stitching to one of the corner sections
52
,
54
,
56
,
58
of the floor panel
50
. The other end
44
of each separator
40
corresponds to the open top
16
of the container
10
. The side panel separators
40
are preferably formed from a stretch-resistant material similar to the material used for the seam covers
28
or the edging
26
.
As shown in
FIG. 6A
, each rectangularly-shaped side panel
20
includes a top side
32
corresponding to the open top
16
of the container
10
, a floor side
34
attached to one of the sides
51
,
53
,
55
,
57
of the floor panel
50
, and two lateral sides
36

38
. Referring just to
FIG. 6A
, each lateral side
36
and
38
is attached to a side panel separator
40
adjacent to the side panel
20
.
As depicted in
FIGS. 4 and 8
, the handles
60
and
62
have both ends connected to the top side
32
of two opposing side panels
20
. The handles
60
and
62
are formed from a stretch-resistant material having a mesh web that extends between a portion of each strap side. The handles for the present invention are not limited to the particular type shown in
FIGS. 4 and 8
. Several alternate embodiments are shown in
FIGS. 9 through 12
, illustrating different handle members. In
FIG. 9
, the handle members
60
and
62
are straps stitched to opposite side panels.
FIG. 10
depicts an alternate embodiment wherein the handle members
60
and
62
are apertures or openings formed in the webs
24
of two opposite side panels
20
. In
FIG. 11
, one handle member
60
is shown as a strap coupled to diagonally opposed side seam separators
40

As shown in
FIG. 13
, an optional storage pouch
70
may be formed from a foldable material, such as nylon mesh, and stitched to the side
32
of one of the side panels
20
. The storage pouch
70
is dimensioned to accommodate the container
10
in its collapsed state as later described.
Although stitching is presented as the preferred means for attaching or connecting the elements of the container
10
and permitting relatively convenient folding of the container
10
, it is to be understood that other methods of attachment can be used in this invention. Such of methods may include heat sealing, gluing and the like. Accordingly, construction of the collapsible container should not be limited to stitching alone.
FIGS. 14 through 17
depict an alternative embodiment of the collapsible container
12
. The container
12
further includes a divider panel
80
. Divider panel
80
is connected to opposite side seam separators
40
thereby dividing the interior of the container
12
into two separate chambers.
FIGS. 18
to
21
show a second alternate embodiment of the collapsible container
14
. The container
14
comprises six side panels
20
and two divider panels
80
and
82
. The divider panels
80
and
82
are arranged substantially parallel to one another. Each divider panel
80
and
82
is made out of a foldable material, such as nylon mesh, and has two sides
86
and
88
stitched to webs
24
of two opposite side panels
20
. The divider panels
80
and
82
separate the interior of the container
14
into three separate compartments for improved sorting and storage of objects.
FIGS. 22
to
30
show various stages in the manufacturing process of the preferred embodiment of collapsible container
10
. Referring to
FIGS. 22A and 22B
, the step of stitching the handle
60
to the top side
32
of two (2) of the webs
24
is shown. Specifically, the stitching is shown at
90
.
In
FIG. 23
, a seam cover
28
is partially stitched to side
21
of each of the four (4) webs
24
. In the two (2) webs having handles
60
or
62
, the seam cover
28
is placed and sewn opposite to the handle
60
or
62
. Each seam cover
28
is preferably placed in the middle of the side
21
and includes a flap or unstitched portion, but it is to be understood that it could be placed anywhere on any side of each of the webs
24
. Referring now to
FIG. 24B
, the edging
26
is then folded in a channel-like fashion around the periphery of the web
24
and stitched to the web
24
, surrounding the perimeter of the web
24
. The stitching is shown at
28
. The stitched edging
26
forms a pocket
25
around the periphery of each web
24
. In the preferred embodiment, each container
10
requires four (4) webs
20
. The two (2) sides including the web
24
, edging
26
and seam cover
28
are shown in FIG.
20
and the two (2) sides including the handle
60
, web
24
, edging
26
and seam cover
28
are shown in FIG.
25
. Stitching of each edging
26
starts and ends at the seam cover
28
, thereby leaving a small space between ends
27
and
29
of each edging
26
.
In
FIGS. 26A and 26B
, the next step involves stitching each corner section
52
,
54
,
56
,
58
of the floor panel
50
to the end
42
of each side panel separator
40
. The stitching is shown at
46
. Now referring to
FIGS. 27 and 28
, the step of attaching each of the four side panels
20
by means of stitching to the floor panel
50
and the side panel separators
40
is shown. The two (2) side panels
20
containing the handles
60
and
62
should be positioned opposite each other with the handles
60
and
62
facing inwardly toward each other. First, the floor side
34
of each of the side panels
20
is stitched to one of the sides
51
,
53
,
55
,
57
of the floor panel
50
as shown in FIG.
23
. Still referring to
FIG. 23
, next the lateral sides
36
of each of the side panels
20
is stitched to the corresponding adjacent side panel separator
40
. As shown in
FIG. 28
, once the first lateral side
36
of a side panel separator
40
is stitched on one side, the second lateral side
38
of another side panel separator
40
is stitched to the other side. The resulting enclosure
90
is shown in FIG.
29
.
As discussed previously, the container
10
may be constructed without the side panel separators
20
. In constructing the embodiment without side panel separators, the two (2) side panels
20
containing the handles
60
and
62
are positioned opposite each other with their handles
60
and
62
facing inwardly toward each other. The floor side
34
of each of the side panels
20
is stitched to one of the sides
51
,
53
,
55
,
57
of the floor panel
50
. Next the lateral sides
36
of each of the side panels
20
are stitched to an adjacent side panel
20
thus forming the container
10
having an open top
16
.
The final steps of the manufacturing process of the present invention involve inserting the frame
22
in one of the open ends
27
or
29
of each of the edgings
26
as shown in FIG.
30
. The frame
22
is passed through the edging
26
and around the periphery of each of the side panels
20
. The ends of the frame
22
are joined together such that the frame
22
forms a continuous loop. In the preferred embodiment, the frame ends are connected by inserting each end into a butt connector and crimping the connector. Finally, the unstitched portion of each seam cover
28
is stitched to side
21
of each web
24
and over the ends
27
and
29
of each edging
26
, thereby protecting the frame
22
from escaping the edgings
26
.
From the expanded state, the container
10
may be folded into a collapsed state for storage and transportation.
FIGS. 31
to
36
show various steps for collapsing the container
10
. Referring to
FIG. 31
, the first step requires grasping opposite sides of the container
10
and biasing one toward the other until all side panels
20
are adjacent and overlie each other. The next step includes inserting the handle members
60
and
62
and the floor panel
50
in between any two of the adjacent overlying side panels
20
is shown in FIG.
32
. It is important to make sure that the storage pouch
70
remains outside of the collapsed side panels
20
. In the preferred embodiment, the resulting partially collapsed container
10
is a stack of four side panels
20
.
FIGS. 33 and 34
show the next step of rotating two opposite corners
101
and
103
of the partially collapsed container
10
in opposite directions while biasing the corners
101
,
103
toward each other. The container
10
will first twist and then will rotate to form three overlying circular loops
150
situated adjacently as shown in FIG.
35
. The final step, shown in
FIG. 36
, is the insertion of the collapsed container
10
into the storage pouch
70
.
When the collapsed container
10
is removed from the storage pouch
70
, the frame members
22
will bias the container
10
into its fully expanded state. Again, the fully expanded state of the preferred embodiment is that shown in FIG.
4
.
The foregoing is considered as illustrative only of the principles of the invention. Furthermore, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described. While the preferred embodiment has been described, the details may be changed without departing from the invention, which is defined by the claims.
