Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] The application claims the benefit under 35 U.S.C.
.sctn.119(e) to Provisional Patent Application No. 61/478,327 filed
Apr. 22, 2011, the entire contents of which are incorporated herein
by reference.
BACKGROUND
[0002] Collapsible containers are known having four or more
flexible side panels with twist-and-fold frames. The side panels
are folded on top of each other and the frames twisted into
overlapping coils to form a compact structure for shipping and
storage. But folding the frames into overlapping coils creates a
stored container that readily springs open. Rubber bands are
sometimes used to hold the coiled frames in the collapsed
configuration, or the coiled container is fit into a bag that is
often sewn to the side of the container as in Pat. No. RE37,924.
But the pop-open tendency of such containers remains undesirable.
Further, collapsing these containers and twisting them into
overlapping coils is difficult for some people. There is thus a
need for a way to more readily collapse the containers for shipment
and storage.
[0003] Because the twist-and-fold containers are made of flexible
material when heavier objects are placed in the containers the
weight of the object deforms the bottom or sides of the containers,
causing adjacent objects to move toward the heaviest object and
impact together. There is thus a need to restrain movement of
objects placed inside the containers, especially heavier
objects.
BRIEF SUMMARY
[0004] A collapsible, twist-and-fold container is provided with at
least one pocket fastened inside the container to hold items. The
container advantageously has four sides, a bottom and a top which
may be open or have a closable cover. The pocket is preferably
located at a corner where the bottom and two sides intersect, with
the pocket fastened to two adjacent sides and optionally fastened
to the bottom as well. Preferably a pocket is located at each
corner of the container. Further, one or more dividers are provided
extending between opposing sides of the container. Releasable
fasteners along opposing edges of the dividers are preferably
provided. Additionally, a hook-and-loop strip is advantageously
placed on the bottom of the container, facing outward, and sized so
that the engagement with the fabric material covering the bottom of
a car trunk is sufficient to restrain lateral movement and sliding
of the container but not so strong as to make it difficult to
disengage the container from the trunk bottom.
[0005] There is thus provided a collapsible container having two
opposing side panels each joined to a top and bottom panel to form
a ring. Each of the side, top and bottom panels has a flexible a
tension loop frame covered by flexible material. The ring has two
opposing ends each covered by an end panel. The ring and end panels
form an enclosure with a plurality of interior corners adjacent
each of the end panels. At least one interior pocket is formed in
one of the corners and adjacent the bottom panel. The interior
pocket is fastened to one of the side panels and the end panel
adjacent the corner. The pocket has an open top facing toward the
top panel and may be optionally fastened to the bottom panel.
[0006] In further variations, the collapsible container has an
opening in the top panel and wherein there are at least four
interior pockets in four interior corners adjacent the bottom
panel: Moreover, the container may have a cover over the opening in
the top panel with the cover being releasably fastened to the
container. The container may also optionally have at least one
exterior pocket on the outside of the container, and handles on the
side panels or end panels. The container may also have an end pull
on each of the end panels to help pull the end panels outward and
facilitate collapsing of the container.
[0007] There is also provided an improved collapsible container
having four tension-loop panels covered by flexible material with
each panel joined to two other panels to form an enclosure with
opposing top and bottom panels and two opposing side panels. The
container has two flexible ends each located on opposing ends of
the frames and attached to a plurality of the frames. The improved
container has an opening in the one of the panels and at least one
interior pocket having two opposing sides with each side fastened
to a flexible side panel or flexible end. The interior pocket has
an open top.
[0008] In further variations this improved container has the
interior pocket further fastened to the flexible bottom panel.
Moreover, the improved container may have a quadrilateral shape
with eight corners and are at least four interior pockets, each
interior pocket located at the four corners opposite the opening
which is in the top panel. Further, the container may have an end
pull on each of the flexible ends, with the end pull located at or
adjacent to the middle of the end. Also, the container may have at
least one external pocket fastened to the outside of the container.
A cover may be placed over the opening with the cover releasably
fastened to the container. One or more handles may be fastened to
the container, preferably fastened to one or more of the tension
loop frames. When the container is placed in the trunk of a vehicle
the container may have a hook and loop fastener strip on the
outside of the bottom panel. The fastener strip is preferably
aligned with a diagonal line extending between two of the corners
of the bottom panel. The tension loop frames may be too stiff to be
twisted and formed into three overlapping coils. A divider panel
can extend between opposing side panels and releasably fastened to
at least one of the side panels.
[0009] There is also provided a method of folding a collapsible
container where the container has a quadrilateral shape with eight
interior corners formed by four panels covered by flexible material
with each panel each having a tension loop frame. Each panel is
also joined to two adjacent side panels to form a ring. Two
flexible ends join to opposing ends of the tension loop frames to
form an enclosure. Two of the panels form opposing side panels
which are separated by and joined to opposing top and bottom
panels. The method includes the steps of pulling on a first end
pull fastened to one of the ends and extending outward from that
end so as to move that end outward. The method also includes moving
a corner of a first of the side panel that is adjacent that end
pull toward a corner of the bottom panel connected to that first
end panel so as to help place the first side panel adjacent the
bottom panel.
[0010] The method can also optionally include the steps of pulling
on a second end pull fastened to the other end and extending
outward from that other end so as to move that other end outward.
The method can further include moving a corner of the first of the
side panel adjacent that second end pull toward a corner of the
bottom panel connected to that other end panel to place the first
side panel adjacent the bottom panel. The method also includes
folding the second side panel toward the first side panel to form a
stack of four panels.

DETAILED DESCRIPTION
[0028] Referring to FIGS. 1-6, a collapsible container 10 is
provided having at four panels 12 connected to opposing ends 14 and
16. An opening 18 is formed in one of the panels 12 or ends 14, 16
to allow access to the inside of the container with a releasable
cover or lid 20 covering the opening. A releasable fastener 22 such
as a zipper releasably fastens the cover 20 to the top 18. Other
releasable fasteners can be used, such as toggles, snaps, buttons,
hook and loop fasteners, etc.
[0029] Each panel 12 is connected to a tension loop frames 24 (FIG.
9) which holds the side panels 12 taut during use. Typically the
loop frames 24 are made of spring metal or made of plastic, and
have circular or rectangular cross sections, although various
cross-sectional shapes and materials can be used. The loop frames
24 and side panels 12 are preferably, but optionally, generally
rectangular in shape, with the long side horizontal. The side panel
frames 24 are joined along the long, horizontal side in the
orientation shown in FIGS. 1-6. The frames 22 are typically placed
in the edging 26 which forms a hollow tube or lumen around the
outer portion and preferably around the periphery of the panels 12,
with the edging 26 and panels 12 defining the shape of the tension
loop frames 22 and panels 12. The edging 26 can be sewn together to
connect the panels 12 and adjacent frames 24.
[0030] Discontinuous frames 24 can be used in lieu of the
continuous loop frame. Such discontinuous frames combine the
adjacent frames into a single piece along the adjoining sides of
panels 12, with separate ends adjacent end panels 14, 16. Such
discontinuous frames are described in more detail in U.S. Pat. No.
7,845,507, the complete contents of which are incorporated herein
by reference.
[0031] Short panel spacers comprising strips of material fastened
to two adjacent sides of panels 12 can also be used to join two
adjacent panels 12. Such side panel separators are described in
RE37,924, the complete contents of which are incorporated herein by
reference.
[0032] The panels 12 and ends 14, 16 (and cover 20) may be made of
flexible material such as fabric, Nylon, canvas, plastic etc. The
material may be a flexible but solid material that blocks air
passage, a woven material that may allow some air passage, or a
mesh material with holes allowing ready passage of air. The
material may be an insulated, flexible material, preferably having
a double wall construction to retain heat or cold within the
container 10. The container 10 walls 12 could be lined with PEVA,
foam or other thermal insulation that is flexible, or in
sufficiently small solid segments to allow flexing of the sides
12.
[0033] Referring to FIGS. 6-9, the inside of the container 10 at
least one interior pocket 30 is formed and fastened to at least one
panel 12 and/or end 14 or 16. The interior pocket 30 may comprise a
sheet of flexible material with two opposing sides 32a, 32b with a
top 32c and bottom 32d. The sides 32a, 32b may be fastened to the
same panel 12 or to the same end 14 or 16, but the depicted
interior pockets 30 are preferably located in each of the four
corners of the container 10, located adjacent the panel 12 forming
the bottom of the container and which is opposite the panel
containing the opening 18. The depicted interior pockets 30 have
one side 32a fastened to a flexible panel 12 and other side 32b
fastened to end 14 or 16 so the interior pocket 30 is defined in
part by a side panel 12, one end panel 14 or 16, and the panel 12
forming the bottom of the container 10. The bottom of the pockets
may be fastened to the panel 12 forming the bottom of the container
10, but advantageously are not fastened and instead end close to
that bottom panel so large items do not slip out of the pocket
readily but a person can insert their fingers into the bottom and
urge things out the top of the pocket. The top of the interior
pocket 30 is preferably open so items can be inserted through the
opening 18 directly into the interior pocket 30. The interior
pockets 30 thus preferably have an open top facing the opening 18
and a bottom adjacent to but not fastened to the adjacent bottom
panel 12. The interior pockets 30 may be sized to hold items of
predetermine size and shape, such as a bottle of wine. An elastic
member may optionally be fastened to the top side 32c of the
pocket. FIG. 7 shows four pockets 30, one in each corner. But the
number and locations of pockets 30 can vary, with FIGS. 15-16
showing three pockets 30 in each end 14 and 16. The pockets may
also be fastened only to the side panels 12, or combinations of
side panels and ends.
[0034] The interior pockets 30 may be permanently fastened to the
panel 12 or ends 14, 16 by various means, including, but not
limited to sewing, adhesives and rivets. Removable fastening
mechanisms can also be used, including, but not limited to hook and
loop fasteners, snaps and buttons. The interior pockets 30 may be
made of the same material as panels 12, or of different material.
Mesh interior pockets 30 are preferred.
[0035] Referring to FIGS. 7-8, one or more dividers 36 which may be
affixed to opposing side panels 12, or which may be releasably
fastened to the side panels similar to the connection of interior
pockets 30 to the container 10. The bottom of the dividers 36 may
be fastened to the panel 12 forming the bottom of the container 10
and opposite the opening 18, or the dividers may end adjacent to
that bottom panel but not be fastened to it. If the dividers 36 are
permanently fastened to the opposing sides of the container 10 then
they are preferably flexible and will restrain folding of the
panels 12 or distort the frames 26 when the panels are stacked. If
the dividers 36 are permanently fastened only to one of the panels
12 and releasably fastened to the opposing or adjacent panel 12,
then the divider may be flexible or stiff. The dividers 36
preferably extend across the entire width of the side panel 12 to
which each side is attached, but may extend only part of the
way.
[0036] Referring to FIGS. 1-6, one or more exterior pockets 38 may
be fastened to the outside or exterior of the side panels 12 or
ends 14, 16. The exterior pockets 38 have an open top 39, allowing
items to be inserted into the pockets. The opening 39 is preferably
located adjacent the top panel 12 containing opening 18 as shown in
FIG. 1. The pockets 38 preferably have two opposing sides and a
bottom fastened to the panel 12 (or end 14, 16) to form a four
sided pocket 38, but differently shaped exterior pockets could be
provided. A mesh material is shown on each of the three exterior
pockets 38 in FIGS. 1-6 and on the interior pockets 30 in FIGS.
7-9, but other material can be used, and different numbers and
locations of exterior pockets can be used.
[0037] Referring to FIG. 5, the outward facing side of the panel 12
forming the bottom of the container 10 may have a releasable
engaging member 40 on it. The releasable engaging member 40
preferably comprises the hook portion of a hook and loop fastener.
The releasable engaging member 40 is preferably oriented diagonally
toward opposing corners of the container 10, and may be continuous
or intermittent. If continuous, the releasable engaging member 40
preferably passes through the approximate center of the panel 12
forming the bottom of the container. The member 40 is sized so that
it engages the nap of fabric or rug commonly found on the bottoms
of car trunks in order to keep the container 10 from sliding around
when empty or with items in the container. The releasable engaging
member 40 is small enough so that a person can lift the container
10 and disengage the member 40 from the trunk material. If the area
of the member 40 is too large that is hard to do. A removal force
of about 3-20 pounds is preferred, with 5-10 pounds preferred. The
diagonal orientation of the engaging member 40 allows a single
strip to be used to restrain motion in two orthogonal directions in
the plane of the (normally flat) trunk, while minimizing the
material used. Alternatively, the releasable engaging member 40
could be placed along a portion of each side of the panel 12 on
which the container 10 rests during use, or placed along opposing
sides, or placed along only one side.
[0038] Referring to FIGS. 1 and 6, handles 42 may be fastened to
one or more of the sides 12 or ends 14, 16. Various types of
handles 42 may be used, but the handles 42 are preferably made of
flexible material, such as Nylon. The handles 42 are attached at
one, and preferably two ends of the flexible strip of material
forming the flexible handle. The ends of each handle 42 are
preferably attached to the same panel 12 or end, 14, 16. The
handles 42 may encircle at least one frame 24 and preferably
encircle two adjacent frames 24 through openings formed in the
respective edging 26. This is described in more detail in U.S. Pat.
No. 6,977,338, and U.S. patent application Ser. No. 12/178,501,
filed Jul. 23, 2008 and published as US2010/0018968, the complete
contents of which are both incorporated by reference. The handles
42 may also be fastened to the material forming the side panels 12
or ends 14, 16. Sewing, adhesives, rivets or other fastening
mechanisms may be used to attach or affix the handles. The handles
42 are preferably located adjacent the top of the container 12, by
the opening 18. The handles 42 on opposing sides or ends of the
container may be connected by a strap 46 having a releasable
connector 48. The releasable connector 48 can include a carbineer,
spring clip or snap clip, among other releasable connectors which
encircle one of the handles 42 or one or more frames 24 adjacent
the connection of the handles 42 to the container 10.
[0039] An optional end pull 44 is fastened to one end 14, 16, and
preferably an end pull 44 is provided on each opposing end. The end
pulls 44 are located between the handle 42 and panel 12 forming the
bottom of the container 10. Advantageously the end pulls 44 are
located at or adjacent to the middle of each end 14, 16. The end
pulls 44 can comprise a tab with one end sewn to the end 14 or 16
and a free distal end. The end pulls preferably comprise a loop of
material with one end fastened to the end 14, 16 and the loop large
enough to pass at least one finger through to pull on the loop. The
end pull 44 can take various forms, including toggles, loops,
straps, handles and buttons. The end pull 44 should be large enough
to be manually grasped by hand and pulled, causing the end 14, 16
to which the end pull 44 is fastened or connected, to extend
outward, as described below.
[0040] Referring to FIGS. 10-13, the folding sequence for the
container 10 is described, with the side panels 12 being referred
to as the front, back, top and bottom panel as shown in the
relative orientation of FIGS. 1 and 6. When the containers 10 are
made, they often end up on the expanded configuration shown in
FIGS. 1 and 5. To collapse the container 10 for shipment or
storage, the panels 12 are folded on top of each other to form a
stack of panels 12. Any divider 36 extending between opposing
panels 12 impedes folding the panels 12 on top of each other. Thus,
any divider 36 should be preferably disconnected or unfastened from
one opposing side wall 12. The divider 36 can be left connected to
one panel 12 as long as the divider 36 is placed adjacent to the
panel to which it is left fastened, or if the panel is stiff, it
may be folded adjacent to the panel 12 to which it is fastened so
as not to not interfere with folding the panels into a stack of
four panels. If the divider 36 is left connected it will deform the
frames 26 abutting the top of the divider.
[0041] When the material on the panels 12 is thick or stiff, it is
difficult to fold the panels 12 adjacent to each other and the
material forming the ends 12, 14 gets in the way and impedes
folding the panels 12 on top of each other. By pulling outward on
the end pulls 44 the ends 14, 16 do not impede the folding of
panels 12 on top of each other. Thus, the end pulls 14 are pulled
outward to make it easier to fold the front panel 12 inward against
the bottom panel as seen in FIGS. 10-11. This may be done by
pulling one end pull 44 with one hand while positioning the
adjacent corner of front panel 12 at the same time. As the front
panel 12 is folded against the bottom panel the top panel is folded
against the back panel 12 since the front and top panels are joined
along an edge. Alternatively described, the front, top edge of the
container 10 is placed against the inside, back edge of the
container, with the ends 14, 16 moved out of the way by use of the
end pulls 44. The result is two adjacent stacks of two panels,
although the stacks are often inclined relative to each rather than
being flat as shown in FIG. 12. The ends 14, 16 can be moved
between the two sets of folded panels before they are folded to
form a stack of four panels as shown in FIG. 13, or the ends 14, 16
may be folded around one side or the other of the four stacked
panels. The strap(s) 42 may also be positioned between the panels
12 as they are folded to allow the stacked panels 12 to hold the
handles 42 and ends 12, 14 generally within or on the stacked
panels.
[0042] The stack of four side panels 12 may then be twisted into
overlapping coils is the material on the panels 12 and divider(s)
36 allows. Alternatively, the panels may be left flat and shipped
in that flat, stacked configuration. Since the flat, stacked
configuration has no coiled frame 24 resiliently urging the panel
12 into an expanded configuration, the stacked assembly is stable
and does not tend to spring open. The stack may be placed in
packaging for sales, typically consisting of clear plastic wrap
with cardboard inserts bearing promotional material. To unpack the
stacked panels 12, the panels are pulled apart manually in the
reverse order in which they were stacked. The end pulls 44 may be
pulled apart to help separate the stacked panels 12. After the
container 10 is in its pop-open configuration, the divider(s) 36
may be fastened to opposing panels 12. Since the stack of four
panels 12 can be shipped flat, the spring frame 24 need not be
sufficiently flexible to be twisted into overlapping coils. That
allows thicker, sturdier materials to be used for the container 10,
and allows use of elongated frames made of metal or plastic wire or
tubes which are not flexible enough to be coiled into even two
overlapping loops, let alone coiled into the three overlapping
loops typical of such twist-and-fold containers.
[0043] During use, the interior pockets 30 retain heavier items at
the corners of the container 10, where the spring loop frames 24
and adjoining panels 12 and ends 14, 16 provide more support.
Indeed, the interior pockets 30 fasten to at least two adjacent
walls, such as panel 12 and either end 14, 16. Moreover, the
interior pockets 30 are located so that they extend over or close
to the frame 24 in the bottom panel 12, so the frame can further
support the weight of an item placed in the interior pocket 30
either directly, or by transfer of the weight through the flexible
material of the adjacent panel(s) 12 or ends 14, 16. As the
interior pockets 30 are preferably configured to hold bottles,
fragile items are further isolated from being hit on all sides as
would occur if placed in the middle of the flexible bottomed
container 10.
[0044] Referring to FIGS. 1 and 14, the pockets 30, 38 can be made
of mesh material or a continuous sheet of solid, but flexible
material. Likewise, as shown in FIG. 8, the interior of the
container 10 and of each panel 12 may be covered by a continuous
sheet of solid, but flexible material, preferably of waterproof
material, and more preferably of waterproof and insulated material.
But the interior of the container 10 could have a mesh lining 56 as
shown in FIG. 9. If desired the cover 20 can be made of a
continuous sheet of generally impervious and preferably water proof
material as reflected in FIG. 14. Alternatively, as reflected in
part by FIG. 1, the cover 20 could be entirely of a mesh material
allowing air to pass readily and to allow easy viewing of the
interior of the container 10. Additionally, the cover 20 could be
of two layers, having a mesh covering to allow air passage and
viewing, and also having a continuous sheet of solid but flexible
material to restrict air passage and block viewing, thus allowing
the user to use either covering by folding the continuous sheet of
material inside or outside the container 10.
[0045] As required, detailed embodiments of the present invention
are disclosed herein; however, it is to be understood that the
disclosed embodiments are merely exemplary of the invention, which
may be embodied in various forms. Therefore, specific structural
and functional details disclosed herein are not to be interpreted
as limiting, but merely as a basis for the claims and as a
representative basis for teaching one skilled in the art to
variously employ the present invention in virtually any
appropriately detailed structure.
[0046] The above description is given by way of example and not
limitation. Given the above disclosure, one skilled in the art
could devise variations that are within the scope and spirit of the
invention, including various ways of fastening the pockets 30, 38
and divider 36 to the container 10. Furthermore, the various
features of this invention can be used alone, or in varying
combinations with each other and are not intended to be limited to
the specific combination described herein. Thus, the invention is
not to be limited by the illustrated embodiments but is to be
defined by the following claims when read in the broadest
reasonable manner to preserve the validity of the claims
