The present invention relates to the field of support systems and more particularly to a bag support system for bags with integrated loop handles.
Every year, Americans throw away more than 100 billion plastic shopping bags after they've been used to transport goods home from grocery stores and other retail and commercial establishments. Only 1 percent of plastic bags worldwide and approximately 2 percent on plastic bags in the United States are recycled. The remaining bags are simply discarded.
The environmental impact of such ubiquitous discarding of shopping bap has a detrimental environmental impact.
The negative environmental impact of plastic bags can be substantially reduced by encouraging the re-use of plastic bags for a variety of functions. For example, items may be sorted, stored, processed and labeled using plastic bags as receptacles.
To be used effectively for these uses, it is advantageous for the plastic bags to be stably supported in an open position. Additionally, it is important that a device that supports plastic bags in an open position be lightweight, low cost, and efficiently packaged to be marketed as a consumer impulse item at the point of purchase and to fully encourage environmentally responsible behavior.
Devices for supporting plastic bags in an open position are known in the art. One example of a bag support is illustrated in U.S. Design Patent No. Des. 428,544 (Moffitt '544).
U.S. Pat. No. 6,199,802 (Scheibe '802) and U.S. Pat. No. 6,651,942 (Yardly '942) disclose collapsible devices for supporting a plastic bag. Both Scheibe '802 and Yardly '942 have a ring or hoop that is used to support the mouth of the plastic bag and a plurality of legs to support the ring or hoop above the ground.
Scheibe '802 secures the plastic bag inside the ring using a plurality of clips, while the outside of the hoop taught by Yardley '942 contains a plurality of tabs to engage and retain the bag mouth by friction.
The present invention is a bag support system that includes a plurality of crossbars, legs, and lateral supports. Each crossbar includes at least one elongated portion. The elongated portions include a plurality of protruding components that are used to secure the loop handles of a plastic bag with integral loop handles inside the bag support system. Each crossbar may removably attach a plurality of lateral supports and legs. When a lateral support has a crossbar attached at each end, the crossbars are offset a pre-determined distance from each other. The legs are adapted to position the crossbars at a pre-determined distance from a surface on which the bag support system stands that is adequate to allow a bag to hang from the crossbars.
It is desirable to have a bag support system that is capable of accommodating plastic bags with varying sizes of loop handles commonly used by retailers.
It is desirable to have a bag support system for bags with integral loop handles that minimizes the amount of space required for storage or transport of the support system.
It is desirable to have a bag support system that is sturdy on surfaces that are not perfectly flat.
It is desirable to have a lightweight, durable, easy to assemble and disassemble, and inexpensive support system for positioning a plastic bag with integral loop handles in an upright and open configuration.
It is further desirable to have a bag support system that is collapsible in a way that allows it to be broken down and stored in a bag to be sold on a hanging display.
Legs 110 include tubular members 115 connected by a coupling 118. Lateral supports 120 include tubular members 125 connected by a coupling 128. In various other embodiments, legs 110 and/or lateral supports 120 may include less than two tubular members.
In the embodiment illustrated in
In an exemplary embodiment, the openings of couplings 118, 128 include draft, with the opening having a slightly larger diameter, facilitating insertion of and engaging of the tubular members 115, 125 by couplings 118, 128. In various other embodiments, another means for ensuring correct assembly may be used such as threading or markings on the tubular members.
Upper crossbars 130 include an elongated horizontal portion 132, horizontal connectors 134 for receiving lateral supports 120, vertical connecters 136 for receiving insertion members 148 of lower crossbars 140.
Lower crossbars 140 include an elongated horizontal portion 142, horizontal connectors 144 for receiving lateral supports 120, vertical connectors 146 for receiving legs 110, and insertion members 140 for attaching lower crossbars 140 to upper crossbars 130.
In the embodiment shown, elongated horizontal portions 132, 142 are hollow and have three sides. The sides of elongated horizontal portions 132, 142 that face outward when bag support system 100 is assembled include a plurality of support knobs 150 for securing the handles of a plastic bag (see
In the embodiment shown, elongated horizontal portions 132, 142 have a square cross-section. In various other embodiments, the dimensions and/or shape of the cross section of elongated horizontal portions 132, 142 may vary. In various embodiments, all four sides of elongated horizontal portions 132, 142 may be enclosed and/or elongated horizontal portions 132, 142 may be solid.
Each support knob 150 preferably includes a neck portion and a larger head portion. Support knobs 150 extend outward from elongated horizontal portions 132, 142. In the embodiment shown, each crossbar 130, 140 has six support knobs 150. In alternative embodiments, elongated horizontal portions 132, 142 may have more or fewer support knobs 150 and/or have differently shaped support knobs 150, including but not limited to hexagon-shaped, square, triangular, diamond-shaped; polygonal or of another shape that is capable of securing a plastic bag without making it difficult to remove the bag when it is full. In still other embodiments, there may be more than two rows of support knobs, the configuration of which may be varied.
In the embodiment shown, horizontal connectors 134, 144 and vertical connectors 136, 146 have a diameter of approximately 0.5 inches and include sufficient draft to facilitate insertion of lateral supports 120, and legs 110, respectively.
Vertical connectors 146 are angled slightly outward causing legs 110 to be angled slightly outward, which results in more stability on various uneven or soft surfaces, such as grass or sand.
In the embodiment shown, the cross-sections of insertion members 148 are cross-shaped and include a draft. In various embodiments, the shape and/or length of insertion members may vary. For example, insertion members may be tubular, triangular, hex-shaped, or star-shaped.
In the embodiment shown, components are made of plastic, but may be made from any other material known in the art to provide a suitably rigid structure, including, but not limited to, wood and metal.
When plastic bag 170 is supported by bag support system 100, any logo printed on the bag will be displayed providing additional brand exposure when plastic bags 170 are reused.
