DETAILED DESCRIPTION
The present disclosure describes various containers. According to various embodiments, the container may include pliable panels that facilitate accommodating objects that may otherwise not fit into a container with rigid panels. The pliable panels and/or other portions of the container may be constructed at least in part from woven polypropylene to provide a relatively high strength container that is mildew resistant. When the container is not in use, the container may be collapsed and folded to reduce the amount of volume that is occupied by the container.
With reference to FIG. 1, shown is an example of a container 103 according to various embodiments of the present disclosure. The container 103 may include multiple side panels 106a-106d that are attached and positioned between a first end panel 109 and a second end panel 111.
At least a portion of the side panels 106a-106d may be pliable. In this regard, at least a portion of the side panels 106a-106d may be flexible. By being pliable, the side panels 106a-106d may facilitate objects being placed in the container 103 that would otherwise not fit in a similar container 103 formed by side panels 106a-106d that were rigid. To provide pliability, the side panels 106a-106d may be constructed at least in part from woven polypropylene and/or any other suitable material.
One or more side panel support members 113a-113d may be attached to the respective side panels 106a-106b. It is noted that the side panel support members 113c-113d are not visible in FIG. 1. The side panel support members 113a-113d may provide structural support for the side panels 106a-106d. For example, the side panel support members 113a-113d may provide support so that the side panels 106a-106d are substantially planar when in the configuration shown in FIG. 1. To provide structural support, the side panel support members 113a-113d may be constructed at least in part from rigid materials, such as metal, plastic, wood, and/or any other suitable material. The side panel support members 113a-113b shown in FIG. 1 are embodied in the form of U-shaped rods, but the side panel support members 113a-113d may take the form of other shapes in alternative embodiments.
The side panel support members 113a-113d may be attached to the respective side panels 106a-106d in various ways. As a non-limiting example, the side panel support members 113a-113d may be attached to the side panels 106a-106d by being positioned between the side panels 106a-106d and support member attachments 114a-114b that are sewn onto the respective side panels 106a-106d. The support member attachments 114a-114b may comprise pliable materials, such as woven polypropylene and/or any other suitable material.
One or more of the side panels 106a-106d may include a pocket 116 for a label 119. In some embodiments, the pocket 116 may comprise a material that is transparent to visible light so that markings on the label 119 are visible through the pocket 116. In alternative embodiments, a user may provide markings directly on the pocket 116 using, for example but not limited to, a non-permanent ink marker.
Additionally, one or more of the side panels 106a-106d may include one or more loops (not shown) that may be slid over, for example, the forks of a forklift. The loops in some embodiments may be constructed at least in part from woven polypropylene or any other suitable material.
One or more of the side panels 106a-106d may include one or more side panel fasteners 123a-123b. The side panel fasteners 123a-123b may be used to restrict the container 103 in a collapsed and/or folded position when the container 103 is in a collapsed configuration, as will be described in further detail below. In this regard, when fastened, the side panel fasteners 123a-123b may maintain the side panels 106a-106d in position so that the container 103 remains in the collapsed configuration until the side panel fasteners 123a-123b are unfastened. According to various embodiments, the side panel fasteners 123a-123b may be embodied in the form of hook and loop fasteners, snap fasteners, tie straps, adhesive strips, and/or any other suitable component that may be used to restrict the side panels 106a-106d to a collapsed position when the container 103 is in the collapsed configuration.
Additionally, one or more straps 126a-126b may be attached to one or more of the side panels 106a-106d. The straps 126a-126b may be held by a user or a machine to facilitate carrying the container 103. The straps 126a-126b may be constructed at least in part from woven polypropylene or any other suitable material. As shown in FIG. 1, the straps 126a-126b may be attached to edges formed between the side panels 106a-106d. In alternative embodiments, one or more straps 126a-126b may be attached to the first end panels 109 and/or the second end panel 111.
As shown in FIG. 1, the first end panel 109 may be attached to the side panels 106a-106d. In some embodiments, at least a portion of the first end panel 109 may be pliable. To provide pliability, the first end panel 109 may be constructed at least in part from woven polypropylene and/or any other suitable material.
The first end panel 109 may include a first flap 129. The first flap 129 may take the form of various shapes according to various embodiments. For example, the first flap 129 shown in FIG. 1 is rectangular. In alternative embodiments, the first flap 129 may be circular, triangular, and/or any other suitable shape. The first flap 129 shown in FIG. 1 has three ends that are separable and closable with respect to the remainder of the first end panel 109. Various types of fasteners may be used so that the first flap 129 is separable and closable with respect to the remainder of the first end panel 109. For example, FIG. 1 shows a first zipper 133 being used as a fastener so that the first flap 129 is separable and closable with respect to the remainder of the first end panel 109. In alternative embodiments, hook and loop fasteners, snap fasteners, buttons, and/or any other suitable fastener may be used so that the first flap 129 is separable and closable with respect to the remainder of the first end panel 109.
One or more flap support members 134 may be attached to the first flap 129. The flap support member 134 may provide structural support for the first end panel 109. For example, the flap support member 134 may provide support so that the first end panel 109 is substantially planar when the container 103 is in the configuration shown in FIG. 1. To provide structural support, the flap support member 134 may be constructed at least in part from a rigid material, such as metal, plastic, wood, and/or any other suitable material. The flap support member 134 shown in FIG. 1 is embodied in the form of a U-shaped rod, but the flap support member 134 may take the form of other shapes in alternative embodiments.
The first flap 129 may also include one or more second flaps 136. The second flap 136 may also take the form of various shapes according to various embodiments. For example, the second flap 136 shown in FIG. 1 takes the shape of a rectangle having a semicircular end. Alternative embodiments may be rectangular, triangular, curved, and/or any other suitable shape. At least a portion of the second flap 136 is separable and closable with respect to the remainder of the first flap 129. For example, FIG. 1 shows a second zipper 139 being used so that the second flap 136 is separable and closable with respect to the remainder of the first flap 129. In alternative embodiments, hook and loop fasteners, snap fasteners, buttons, and/or any other suitable fastener may be used so that the second flap 136 is separable and closable with respect to the remainder of the first flap 129.
As shown in FIG. 1, one or more flap handles 143 may be attached to the second flap 136. In alternative embodiments, one or more flap handles 143 may be attached to the first flap 129. The flap handle 143 may facilitate a user opening and/or closing the first flap 129 and/or the second flap 136. Additionally, the flap handle 143 may facilitate a user carrying the container 103.
As shown in FIG. 1, the second end panel 111 may also be attached to each of the side panels 106a-106d. Additionally, at least a portion of the second end panel 111 may be pliable. To provide pliability, the second end panel 111 may be constructed at least in part from woven polypropylene and/or any other suitable material. In some embodiments, no rigid support elements are attached to the second end panel 111. By not having rigid support elements attached to the second end panel 111, the second end panel 111 may facilitate the container 103 being collapsible, as will now be described.
With reference to FIG. 2, shown is the container 103 with the first flap 129 opened. A user may open the first flap 129 to begin the process of collapsing the container 103. To this end, the user may unfasten the first zipper 133, and the first flap 129 may be positioned within the space formed between the side panels 106a-106d, as shown in FIG. 1.
With reference to FIG. 3, shown is the container 103 being collapsed according to various embodiments of the present disclosure. To cause the container 103 to be in the configuration shown in FIG. 3, a user may press against the edge 303 formed between the side panels 106a-106b and the edge 306 formed between the side panels 106c-106d so that the edge 303 moves closer to the edge 306. This maneuver causes the side panel 106a and/or the side panel 106d to be rotated about the edge 309 formed between the side panel 106a and the side panel 106d. As a result, the angle formed between the side panel 106a and the side panel 106d is reduced. Similarly, the side panel 106b and/or the side panel 106c to be rotated about the edge 313 formed between the side panel 106b and the side panel 106c. As a result, the angle formed between the side panel 106b and the side panel 106c is reduced. When the container 103 has been collapsed, the edge 303 formed between the side panel 106a and the side panel 106b may be positioned adjacent to the edge 306 formed between the side panel 106c and the side panel 106d. 
As shown in FIG. 3, the second end panel 111, which may not have any support members attached thereto, may crumple or fold as the edge 303 is brought closer to the edge 306. Thus, the pliability of the second end panel 111 may facilitate the container 103 being collapsible. A user may also position the straps 126a-126b in the space formed between the side panels 106a-106c during the collapsing process.
With reference to FIG. 4, shown is the container 103 being folded according to various embodiments of the present disclosure. As shown in FIG. 4, the container 103 has been collapsed so that the side panel 106a is substantially flat with respect to the side panel 106d and so that the side panel 106b is substantially flat with respect to the side panel 106c. Additionally, the edge 303 is positioned adjacent to the edge 306, as shown in FIG. 4.
A user may fold the container 103 by rotating the side panels 106a-106b about the edge 303 while simultaneously rotating the side panels 106c-106d about the edge 306 in the directions indicated by the arrows 403 and 406. This maneuver brings the edge 309 closer to the edge 313.
With reference to FIG. 5, shown is the container 103 in a collapsed configuration after the container 103 has been folded. As shown, the side panels 106a-106d are substantially flat with respect to each other. As such, the volume occupied by the container 103 is less than the volume that a non-collapsible container would occupy.
A user may also fasten the side panel fasteners 123a-123b. When fastened, the side panel fasteners 123a-123b may be used to restrict the side panels 106a-106d to be in the position shown in FIG. 5. In this regard, the side panel fasteners 123a-123b may maintain the side panels 106a-106d in the position shown in FIG. 5 so that the container 103 remains in the collapsed configuration until the side panel fasteners 123a-123 are unfastened.
It is emphasized that the above-described embodiments of the present disclosure are merely possible examples of implementations set forth for a clear understanding of the principles of the disclosure. Many variations and modifications may be made to the above-described embodiment(s) without departing substantially from the spirit and principles of the disclosure.
