The subject matter disclosed herein relates in general to portable waste disposal bags, and more specifically to a portable waste disposal bag that is relatively strong in construction, easy for someone to fill with trash or waste products, and quick and easy to safely remove once the bag has been filled.
Known, prior art portable waste disposal bags basically comprise relatively large flexible material bags that are foldable and collapsible in nature. These bags are commonly used for storage, handling, and transportation of junk, trash, garbage, or waste products such as home, garage, and shed structural products, furnishings, and objects resulting from projects such as inside or outside construction, renovations, re-modellings, or cleanouts, as well organic yard debris from clean-ups, and the like. The portable waste disposal bags are popular with home dwellers due to their low cost, wide range of placement locations at a fill site such as on a driveway or yard, and ease of filling and removal.
Also, the bags are typically purchased at retail locations and can be filled by the do-it yourselfer without the need to hire someone to fill it. Once filled, the bags are then usually removed by contacting a service to come and place the bag onto or into a truck for hauling away of the bag. The bags are a favored replacement for typically larger conventional metal dumpsters yet offer a greater amount of waste removal than normal trash removal services. These portable waste disposal bags provide a convenient way to get rid of unwanted household and yard waste.
These known, prior art portable waste disposal bags are typically rectangular in shape both for their sides and bottom. They also have a plurality of handles that facilitate lifting of the bag when partially or fully filled. The lifting is typically carried out by equipment such as the crane of a boom truck, a forklift, or some other machine, as part of the bag removal and waste disposal process.
However, rectangular-shaped bags suffer several drawbacks, including having a relatively large footprint at a fill site such as on a driveway or a yard surface. Also, the rectangular-shaped bag typically does not lend itself to a relatively even distribution of the weight of its contents, which could pose problems when lifting the relatively heavy bag (which can hold up to approximately 3,300 pounds) by the crane of the boom truck, the forklift, or by some other machine. These problems include, for example, not having the machine be able to lift the bag within its weight rating or having some of the waste products fall out of the bag.
Further, the rectangular-shaped bag of the prior art has angled corners inside the bag where the sidewalls meet. Also, oftentimes each of the rectangular sides is comprised of a single piece of the material, which then needs to be joined to each other and to the bottom piece. As such, the rectangular nature of the bag increases the likelihood that waste products placed inside the bag may encounter one or more of the angled corners and/or joints between pieces of material, which then increases the likelihood of the bag being ripped, torn, or otherwise damaged.
Thus, there is a need for improvements to a portable waste disposal bag, notably for a smaller footprint while on a hard surface (e.g., packed dirt or a paved driveway) or on a soft surface (e.g., sand or grass), as well as for a more even distribution of the weight of the contents of the bag when filled, and a reduction in the possibility of ripping, tearing, or damaging the material of the bag.
An object of embodiments of the present invention is to provide a portable waste disposal bag that is made from a relatively strong yet flexible, pliable, and collapsible material.
Another object of embodiments of the present invention is to provide a portable waste disposal bag that has a relatively small footprint while it is located at a fill site on a flat surface such as a paved driveway, dirt, sand, or grass.
Yet another object of embodiments of the present invention is to provide a portable waste disposal bag that can be folded into a generally flat and compact condition when empty.
Still another object of embodiments of the present invention is to provide a portable waste disposal bag that is relatively easy for a person to fill with different types of waste products.
Another object of embodiments of the present invention is to provide a portable waste disposal bag that is relatively easy to pick up and remove once it has been filled.
Yet another object of embodiments of the present invention is to provide a portable waste disposal bag having a round bottom and a cylindrical side and which provides for a relatively more even distribution of the weight of its contents.
According to an embodiment of the present invention, a portable waste disposal bag includes a generally round bottom section, and a generally cylindrical side section that encircles the bottom section and is attached by stitching to the bottom section. The bag also includes at least two lifting straps which are each attached by stitching to the side section. The bottom section, side section and the two lifting straps are each made from a single piece of flexible material such as woven polypropylene. The bottom section and side section form a primary waste holding section configured to hold waste products and which forms means for evenly distributing the weight of an aggregate amount of the waste products held in the primary waste holding section. The means for evenly distributing the weight is configured to be deformable into an overall generally round shape during lifting of the waste disposal bag off of a surface.
The subject matter, which is regarded as the disclosure herein of exemplary embodiments of the present invention, is particularly pointed out and distinctly claimed in the claims at the conclusion of this specification. The forgoing and other features and advantages of the present invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings in which:
It should be understood that, throughout this patent application and specifically in the written description that follows and in the accompanying drawing figures, various directional and orientational terms such as inside, outside, horizontal, vertical, up, down, upwardly, downwardly, front, back, top, bottom, upper, lower, left, right, and other similar terms as they are used herein refer to the portable waste disposal bag of the various exemplary embodiments of the present invention as that bag is oriented when it is typically placed on surface such as a driveway or grass for filling with waste products, and is lifted for removal by a crane of a boom truck, by a forklift, or by a similar machine. All of these terms are used in this written description and in the drawings for convenience only and as an aid to better understanding the exemplary embodiments of the present invention. These terms are not intended to be limiting in the claims appended hereto or to imply that the portable waste disposal bag must be used or positioned in any particular orientation.
Referring to
In the exemplary embodiments of
The portable waste disposal bag 100 also includes a pair of lifting straps 116, 120 that are each attached to the bag 100 such that the straps 116, 120 are arranged opposite each other in parallel. This is done to facilitate the proper and safe lifting of the bag 100 when full of waste products for removal from the fill site and onto a truck for subsequent disposal of the products. The material of the lifting straps 116, 120 may comprise a relatively high-strength flexible woven polypropylene or other suitable strong flexible material similar to that of the bottom section 108 and the side section 112. The material of the lifting straps 116, 120 may be of a greater thickness than the material of the bottom section 108 and the side section 112.
In the exemplary embodiments of
However, it is to be understood that the lifting straps 116, 120 instead may be attached to the inside surface of the side section 112 in accordance with the broadest scope of the present invention. As such, at least a portion of each strap 116, 120 may also be attached to the inside surface of the bottom section 108. Further, at least a portion of each lifting strap 112, 120 may be attached to the outside surface of the bottom section 108. All of these attachment variations are contemplated by the broadest scope of the present invention.
In an exemplary embodiment, the diameter of the round bottom section 108 may be approximately 78 inches, the height of the cylindrical side section 112 may be approximately 33 inches, the width of each of the lifting straps 116, 120 may be approximately 3.5 inches, and the portion of each lifting strap 116, 120 that extends above the top perimeter of the side section 112 may be approximately 40 inches. As such, the portable waste disposal bag 100 holds a maximum of approximately 3.3 cubic yards of waste products, which is a maximum of approximately 3,300 pounds. However, it should be understood that these dimensions for the bottom section 108, side section 112, and lifting straps 116, 120 are purely exemplary. Instead, any suitable desired dimensions for these components 108-120 of the bag 100 may be utilized within the broadest scope of the present invention in light of the teachings herein. The dimensions chosen for the various components 108-120 of the bag 100 may depend on the desired amount of total weight to be safely handled by the bag 100 or the desired total volume amount of waste products to be safely filled inside of the bag 100.
In use, the portable waste disposal bag 100 of the exemplary embodiments of the present invention may be purchased, for example, in person at a retail location, through an online retailer, or by some other method. The bag 100 as sold and transported or shipped may typically be in a folded condition, thereby saving space. The bag 100 may then be brought to a fill site, such as at a house or other building such as a garage or shed, or commercial building. The bag 100 may also be brought to a location apart from a building to be filled with organic yard waste (e.g., tree branches, leaves, etc.).
Once at the fill site, the bag 100 may be unfolded and filled with waste products. After unfolding, the bag 100 may initially be such that the side section 112 is in a collapsed condition. Then after the filling of the bag 100 with waste products begins, the side section 112 may start to assume an upright vertical position such that the bag 100 can support itself in maintaining an upright and open condition. Also, during the filling process, care is generally taken to ensure that the flexible lifting straps 116, 120 are located outside of the primary waste holding section 104 of the bag 100. This allows for proper and easy access to the straps 116, 120 when it is time later on to remove the bag 100 from the fill site.
Referring to
As best seen in
Other advantages that the portable waste disposal bag 100 of the exemplary embodiments of the present invention has over known, similar waste disposal bags of the prior art include that the generally round shape of the bag 100 provides for a smaller footprint when the bag 100 is located on a hard surface (e.g., packed dirt or a paved driveway) or on a soft surface (e.g., sand or grass). This allows the bag 100 to be utilized in physical spaces that are relatively small or confining. Further, the round shape of the bag 100 eliminates the corners found in prior art rectangular bags, thereby reducing the risk that waste products placed inside the bag 100 will rip, tear, or otherwise damage the bag 100.
