Portable and/or collapsible containers having pliable surfaces

Containers provide for portability and ease of handling by being constructed of pliable materials such as various polymers and having additional features. The containers may have biasing members such as tension poles to hold the containers in an upright and open top position and/or may have sleeves that can be engaged by a forklift for dumping of the container by a conventional forklift equipped garbage truck. The containers may include additional features such as loops along a top edge to allow grasping of the loops by a lift and loops along a bottom edge to allow dragging of the container such as onto a flatbed hauler. Additional features may include a top cover that can be pulled over the open top and secured such as by a fastener.

TECHNICAL FIELD

Embodiments relate to containers for holding debris and other materials. More particularly, embodiments relate to containers that include pliable surfaces and that are portable and/or collapsible to provide additional benefits to users.

BACKGROUND

Individuals and businesses often have a need for a container where garbage, debris, and other materials can be placed and later hauled away to a landfill or other appropriate location. Conventional metal garbage dumpsters allow the garbage, debris, and other materials to be hauled away. However, conventional metal garbage dumpsters are too unsightly and awkward to handle for a residence and for many businesses. They can only be moved by large equipment and may be expensive to purchase or rent. Therefore, conventional metal garbage dumpsters do not meet the needs of all situations.

Other approaches such as THE BULL BAG garbage bag offered by The Bull Bag, LLC include an upright garbage bag that requires a user to build the bag by installing braces typically made of plastic tubing and other bracing supports that brace the bag into the upright position. These garbage bags typically include only a set of loops at the top so that a truck with a lift may grasp the garbage bag by the set of loops. However, on the one hand, this may allow the garbage bag to be less awkward to handle than a conventional metal dumpster, but building and breaking down the bag requires additional time, effort, and some degree of construction skill on the part of the user. On top of that, this dump bag approach requires that a special truck service visit the site to pick up the garbage bag which may result in an additional cost that is unacceptable to the user.

SUMMARY

Embodiments disclosed herein may address one or more of these issues and others. For example, some embodiments may provide for a container that includes biasing members that bias opposing edges of the walls of the container so that the container can be folded and unfolded yet can maintain an upright position without the user installing bracing. As another example, some embodiments may provide for a container that includes dump sleeves to allow a conventional forklift to raise the container so that a conventional front end loader garbage truck or any garbage truck with a forklift may raise and dump the container. As other examples, some embodiments may provide both the biasing members and the dump sleeves and may also provide additional features such as loops for vertical pick-up and loops for sliding onto flatbeds.

One or more embodiments provide a container that includes a plurality of pliable wall panels and a pliable floor panel. Each pliable wall panel has a first edge attached to one of a plurality of edges of the floor panel, a second edge attached to an edge of an adjacent pliable wall panel, and a third edge attached to an edge of another adjacent pliable wall panel. The container further includes a plurality of biasing members with each of the plurality of biasing members being attached to a corresponding pliable wall panel of the plurality, the plurality of biasing members biasing opposing edges of the plurality of pliable wall panels to which the biasing members are attached such that the plurality of pliable wall panels define an open top though which materials may be placed into the container.

One or more embodiments provide a container that includes a plurality of pliable wall panels and a pliable floor panel. Each pliable wall panel has a first edge attached to one of a plurality of edges of the floor panel, has a second edge attached to an edge of an adjacent pliable wall panel, and has a third edge attached to an edge of another adjacent pliable wall panel. The container further includes a first sleeve that is attached to a first of the pliable wall panels, and the first sleeve has a longitudinal axis extending between the second edge and third edge of the first wall panel. The container also includes a second sleeve that is attached to a second of the pliable wall panels that is opposite the first of the pliable wall panels, and the second sleeve has a longitudinal axis extending between the second edge and third edge of the second wall panel.

One or more embodiments provide a method of handling debris that involves unfolding a container that includes a plurality of pliable wall panels and a pliable floor panel. Each pliable wall panel has a first edge attached to one of a plurality of edges of the floor panel, has a second edge attached to an edge of an adjacent pliable wall panel, and has a third edge attached to an edge of another adjacent pliable wall panel. The container includes a plurality of biasing members with each of the plurality of biasing members being attached to a corresponding pliable wall panel of the plurality. The plurality of biasing members bias opposing edges of the plurality of pliable wall panels to which the biasing members are attached such that the unfolded container maintains an upright and unfolded position and such that the plurality of pliable wall panels define an open top though which materials may be placed into the container. The method further involves placing debris through the open top and into an interior of the unfolded container.

DETAILED DESCRIPTION

Embodiments disclosed herein provide for portable, collapsible containers that may serve as dumpsters to collect garbage, debris, and other materials while providing ease of handling and emptying. Various embodiments provide containers that include biasing members to bias walls of the container into an open position while allowing the container to be folded into a collapsed position without disassembly of the container. Various embodiments provide containers that include sleeves that receive forks of a forklift such as that of a conventional front end loader garbage truck. Additional features may also be present in various embodiments such as lift loops, drag loops, cover panels, drains, and the like.

FIGS. 1-3show one embodiment of a container that includes many features. As discussed below, other embodiments of a container may have a different configuration of features than those described in relation toFIGS. 1-3. Therefore, it should be appreciated that the embodiment ofFIGS. 1-3is provided merely for purposes of illustration and is not intended to be limiting.

The container100that is shown includes four pliable wall panels102,104,106, and108as well as a pliable floor panel109. In this example, the container100has rectangular panels and a rectangular opening101. It will be appreciated that other shapes and sizes are also possible for the panels and the opening, such as triangular, pentagonal, and so forth.

In the example shown, each wall panel102,104,106, and108and the floor panel109has four edges. Each vertical edge of the wall panels are attached to a vertical edge of an adjacent wall panel. Each bottom edge of the wall panels is attached to a corresponding edge of the floor panel109. The corners of the container100where these vertical edges of the wall panels meet and where the bottom edges meet the floor panel edge may be constructed in various ways. For example, these corners may be formed by stitching with hems using any desired numbers of seams, ultrasonic welds, and so forth depending upon the strength requirements of the container100. It has been found that for wall and floor panels constructed of materials such as woven polyethylene or woven polypropylene, hemmed corners using a high-strength polymer thread for the stitching while including a reinforcement woven polymer sheet sandwiching the adjoining panels and being connected with double seams is one example of a suitable approach. Woven polyethylene and woven polypropylene in the four to seven ounce weight range are examples of pliable but relatively strong materials that are suitable for constructing the wall and floor panels, but other weights and other pliable materials such as non-woven polymers, burlap, and so on are also applicable to the various embodiments.

Additionally, the materials used to construct the pliable wall and floor panels may have additional characteristics. For example, one or more of the pliable wall and floor panels may have an ultraviolet (UV) light protective coating such as those known in the art to reduce or prevent the destructive effects of ultraviolet light on the polymer or other material. Furthermore, one or more wall or floor panels, and particularly the floor panel, may either be constructed of a waterproof material to prevent leaks and leaching for situations where the container100have liquids placed within it. Waterproof material may include materials such as a non-woven polymer or another substance such as a woven polymer that has a coat of sealer such as a polyvinyl chloride (PVC) sealer applied to it.

As the embodiments may include pliable wall and floor panels, the container100also includes structural features to hold the container100upright and maintain the opening101. In certain embodiments such as the one shown, biasing members are included to bias the container100into the upright position with the opening101maintained. In the specific example shown, the biasing members are tension poles such as those used to support tents. These tension poles are unbiased when straight and are held in a bent position as shown to bias opposing edges of the wall panels apart. As a result of this bias of the opposing edges of the wall panels, the wall panels maintain their shape, as a square or rectangle in this particular example, rather than collapsing. It will be appreciated that other forms of biasing members may also be used as an alternative to or in addition to the tension poles that are shown in order to maintain the shape of the wall panels and hence, maintain the upright position of the container100. For example, spring-loaded rods may be included to bias opposing edges of the wall panels apart.

In this particular example, the tension poles are bent to form a 90 degree angle between directions that the ends of the tension poles are pointing with the ends of the tension pole being fixed in proximity to edges of the wall panel. This configuration results in a single tension pole creating tension between both sets of opposing edges of the wall panel. It will be appreciated that different configurations of tension poles may also be utilized. For example, a separate tension pole may be utilized for each edge of a given wall panel.

FIG. 1shows the tension poles of both the side wall panel104and the front wall panel102, whileFIG. 2shows the tension poles of the front wall panel102andFIG. 3shows the tension poles of the side wall panel104. Tension poles may also be included in the side wall panel108and the rear wall panel106to fully support the container100in the upright and open position but are omitted fromFIGS. 1-3to maintain clarity of those figures.

As can be seen inFIGS. 1 and 2, a first section of the front wall panel102includes a tension pole132that has a first end that is positioned within a pouch149of a pouch assembly146located on the inner side at a top edge and at the mid-point of the wall panel102. The opposite end of the tension pole132resides in a pouch142located on the inner side at a corner where a bottom edge and left edge meet. Thus, the tension pole132is effectively attached to the front wall panel102by having the ends of the tension pole132confined to the pouches142,149. The first section of the front wall panel102also includes a tension pole134that has a first end that is positioned within a pouch143of a pouch assembly144located on the inner side at a bottom edge and at the mid-point of the wall panel102. The opposite end of the tension pole resides in a pouch140located on the inner side at a corner where the top edge and left edge meet. Thus, this first section of the front wall panel102is being biased into its square shape to prevent the front wall panel102from collapsing so that the top edge forms a portion of the opening101of the container100.

As can also be seen inFIGS. 1 and 2, a second section of the front wall panel102includes a tension pole136that has a first end that is positioned within a pouch147of the pouch assembly146located on the inner side at a top edge and at the mid-point of the wall panel102. The opposite end of the tension pole136resides in a pouch150located on the inner side at a corner where the bottom edge and right edge meet. The second section of the front wall panel102also includes a tension pole138that has a first end that is positioned within a pouch145of the pouch assembly144located on the inner side at the bottom edge and at the mid-point of the wall panel102. The opposite end of the tension pole138resides in a pouch148located on the inner side at a corner where the top edge and right edge meet. Thus, this second section of the front wall panel102is also being biased into its square shape to prevent the front wall panel102from collapsing so that the top edge forms a portion of the opening101of the container100.

As can be seen inFIGS. 1 and 3, the side wall panel104includes a tension pole120that has a first end that is positioned within a pouch124located on the inner side at a corner where a top edge and rear edge meet. The opposite end of the tension pole120resides in a pouch128located on the inner side at a corner where the bottom edge and front edge meet. The side wall panel104also includes a tension pole122that has a first end that is positioned within a pouch130located on the inner side at a corner where the top edge and front edge meet. The opposite end of the tension pole122resides in a pouch126located on the inner side at a corner where the bottom edge and rear edge meet. Thus, this side wall panel104is being biased into its square shape to prevent the side wall panel104from collapsing so that the top edge forms a portion of the opening101of the container100.

While the container100is shown with the pouches and tension poles located on the inner side of the pliable walls, it will be appreciated that other configurations are also possible. For example, one or more of the tension poles and the corresponding pouches may be located on the outer side of the pliable walls. In some examples, all the pouches and tension poles may be located on the outer side of the pliable walls.

In the unfolded state shown inFIGS. 1-3, the front and real walls102,106take their fully extended position. The container100may be folded without disassembly by forcing the front and real wall panels102,106to bend inward into the two sections along a vertical axis at the mid-point where pouch assemblies144and146are located. The floor panel109folds as necessary to allow the front and rear wall panels102,106to bend inwardly until the side wall panels104,108and both sections of the front and rear wall panels102,106lie within the same plane and have a stacked configuration. In this folded state, the container100requires much less storage space and can be more easily transported. Once positioned at the desired location, the stacked configuration of wall panels may be unstacked by completely unbending the front and rear wall panels102,106about the vertical axis at their mid-point and allowing the bias being applied by the tension poles to continue maintaining the shape of the wall panels to thereby maintain the container100in the upright and open position.

The pouches discussed above may be constructed in various ways. For example, as shown inFIGS. 4A-4C, a pouch140may be constructed as a single piece of pliable material208, such as woven polyethylene or woven polypropylene, that is folded over at one end as shown inFIG. 4A, and then stitched along the outer sides210,212as shown inFIG. 4B. By only stitching the sides210,212, the bottom edge is left unattached so that an end of a tension pole may be received into the pouch140.

As shown inFIG. 4Cthe tension pole134is inserted into the pouch140. In this particular example, additional material141is inserted into the pouch140prior to introduction of the tension pole134. This additional material141strengthens the pouch140by preventing the end of the tension pole134from pressing through the folded end of the pouch140due to the bias forces applied by the end of the tension pole134to the pouch140.

In the example shown, the tension poles can be readily inserted and removed from the pouches. This allows all tension poles to be removed such that the container100can be completely collapsed and folded as desired such as when storing the container100for a long period of time or when transporting. The tension poles may be re-inserted into the corresponding pouches to then allow the container100to regain and maintain its upright and open position.

Various embodiments of the container, such as embodiments like container100that use biasing members to maintain the upright position or embodiments that do not use such biasing members, may include dump sleeves112,114as shown inFIGS. 1-3. These dump sleeves112,114allow a forklift to raise and lower the container100such as when a conventional front end loader garbage truck is dumping the container. In the embodiment shown inFIGS. 1-3, the dump sleeves are included on the side wall panels104and108and are positioned so that the dimension between the dump sleeves112and114matches the width of the forks of a forklift of a conventional front end loader garbage truck. Furthermore, the height of the openings of the dump sleeves112and114match the height of the forks of the forklift of the conventional front end loader garbage truck when in the lowered position. Thus, the forks of the forklift may be easily inserted into the dump sleeves112and114by the forklift operator in the same manner that is done when lifting a conventional metal dumpster.

In the embodiment ofFIGS. 1-3, the dump sleeves112and114are shaped as sleeves having a longitudinal axis of the opening running from the front to the rear of the side wall panels104and108. The dump sleeves112,114of this embodiment include a tubular region202that establishes the opening and also include a lower region204below the tubular region202where the material of the dump sleeves112,114overlaps onto itself as can be seen inFIG. 5A. These lower regions are stitched together as can be seen inFIG. 5Band are then stitched to the side wall panels104,108.

The dump sleeves112,114support the weight of the container100and all of the debris within the container upon a forklift raising the container100by the dump sleeves112,114. Therefore, in certain embodiments it may be desirable to further reinforce the attachment of the dump sleeves112,114to the side wall panels104,108. In the embodiment shown, a reinforcement panel116is located on the inner side of the side wall panel104and a reinforcement panel118is located on the inner side of the side wall panel108. The dump sleeves112,114which are located on the outer side of the side wall panels104,108are then stitched through the side wall panels104,108and into the reinforcement panels116,118.

In certain embodiments such as the one that is shown, it may be desirable to assist the tendency of the container100to properly dump into the garbage truck upon being raised and tilted by the forklift. In the embodiment shown, the tendency of the container100to dump properly upon being raised is increased by providing dump sleeves112,114with a longitudinal axis of the opening that is angled relative to the bottom edge of the side wall panels104,108as is best seen inFIG. 3. Here, the end of the dump sleeve112that is closest to the rear edge of the side wall panel104is lower than the end of the dump sleeve112that is closest to the front edge of the side wall panel104where the forklift is inserted. Thus upon introduction of the forks into the dump sleeves112,114, the container100is tilted forward to assist in properly dumping the contents of the container100when being raised and tilted by the forklift.

Also best seen inFIG. 3, in certain embodiments an end cap111may be stitched onto or otherwise attached to the end of the dump sleeve112,114that is closest to the rear edge of the side wall panel104,108. This end cap111receives the tip of the forks of the forklift to prevent the container100from sliding farther than necessary onto the forks of the forklift to thereby also assist in the proper dumping of the container100.

The dump sleeves112,114may be made of various materials. Some examples include woven polyethylene or woven polypropylene that may also be used for the wall and floor panels of the container100. Where the materials used for the dump sleeves112,114are pliable, it may be desirable to include a circular or semi-circular stiffener206as shown inFIG. 5Cthat is installed inside the tubular regions202to hold the tubular regions202in the open position. Maintaining the tubular regions202in the open position ensures that the forks of the forklift can be easily inserted. Examples of materials used for the stiffener206include hard but somewhat flexible plastic, flexible metal, and so forth. It may be desirable for the stiffener206to have some flexibility so that the sleeve deforms slightly upon the container100being lifted.

Various embodiments of the container100may include additional features including those shown for container100ofFIGS. 1-3. For example, lift loops152,154may be included for embodiments that include the biasing members and/or the dump sleeves to provide an additional manner of lifting the container100. While two lift loops152,154are shown in some of the figures for purposes of clarity, it will be appreciated that additional lift loops may be included such as a lift loop at each corner along the top edge of the container100, such as additional lift loop153ofFIGS. 2 and 3. The lift loops may be made of various materials such as a soft polymer webbing and the like. The lift loops may extend down the corners by a substantial amount, for example18inches, and be stitched into the seams used to create the corners so as to reinforce the lift loop and its attachment to the container100.

Another additional feature that may be included for certain embodiments is one or more drag loops174,175. As shown, the drag loops174,175are sewn to the junction of the bottom edge of the side wall panels104,108and the edge of the floor panel109. The drag loops174,175may be used to drag the container100from one location to another, such as onto a flat bed truck that may haul away the container100. The drag loops may be constructed of various materials such as the same materials used to construct the lift loops152,154.

Another additional feature that may be included for certain embodiments is one or more drains holes and corresponding grommets176,178. These drains may allow the container100to be emptied of certain materials such as liquids and granular materials that are contained within it while the grommets may be included to define the hole and prevent the pliable material from tearing or otherwise coming apart. For embodiments where the container100is expected to hold liquids without leaking or leaching, the drain holes176,178may be omitted or plugged.

Another additional feature that may be included for certain embodiments is a top cover110. This top cover may be attached to the container along a top edge of one of the wall panels, such as the rear wall panel106as shown. The top cover may be constructed of a pliable material such as the same material used to construct the wall panels or floor panel109. Fasteners may be used to hold the top cover110down to close the opening101of the container100. One example of a fastener is a hook and loop fastener as shown, where the wall panels include one side156,158,160,162of the hook and loop fastener while the top cover110includes the mating side164,166,168,170,172of the hook and loop fastener. As another example, a zipper may be used to hold the top cover110in the closed position where one side of the zipper track is included along the top edge of the pliable wall panels while the other side of the zipper track is included along the outer edges of the top cover110such that the outer edges of the top cover110are held to the top edge of the wall panels upon closing the zipper.

An example of dimensions of a rectangular container such as the one shown will now be discussed for the purpose of illustration. This example is not intended to be limiting but merely provides dimensions of one example of a container that can be dumped by a conventional garbage truck. It will be appreciated that many variations in the dimensions and shapes of embodiments of the container may be applicable to a given situation. In this example, the width of the unfolded container is about 72 inches while the height is about 38 inches and the depth is about 36 inches. The folded container has dimensions of about 4 inches by 38 inches by 36 inches.

In this example, the pouches are approximately 5 inches tall, with a width of about 2.5 inches and with the flap forming the enclosure of the pouch being about 3 inches in length so that about 3 inches of the tension pole end is within the pouch. The opening of the dump sleeves is about 9.5 inches in diameter. The height of the top edge of the dump sleeve at the front is about 23.75 inches while the height of the top edge of the dump sleeve at the rear is about 21.25 inches.

As discussed above, various embodiments of containers provide features such as biasing members and/or dump sleeves that may increase the level of convenience and usability of the container. While embodiments have been particularly shown and described, it will be understood by those skilled in the art that various other changes in the form and details may be made therein without departing from the spirit and scope of the invention.
