The present invention relates generally to the field of dog waste collection, and more particularly to methods and systems for dog waste bag dispensing.
When walking one's pet it is common to bring a device that holds pre-rolled waste bags, such as shown in U.S. Pat. No. 7,850,039B1, in order to pick up one's pet's excrement while on a walk.
The state of the current art is similar to that of U.S. Pat. No. 8,113,381B2, wherein small lightweight devices are added to one's existing leash, but are designed to only hold one roll of waste bags. Though devices such as US20220356001A1 exist to show the roll as a means of estimating the number of bags left, it is very difficult to predict how many bags are left by looking at a roll. Similarly, having to look at the holder and predict the number of bags left is one additional step to have to remember before taking one's pet for a walk.
Oftentimes pets will need to use one or more bags for a walk, especially if one is walking multiple pets. If one's holder has no bags left, or even if there are one or two left, this will leave one in a situation where they will need to pick up the pet's excrement, but have no waste bags left to do so.
While some solutions do exist, they go towards the extreme of full leash organization assemblies, like US20210227794A1, wherein a large bulky assembly is rigidly mounted to an existing leash and contains many features in addition to waste bag storage, like a holding area for treats. For one walking their pet, adding a large clunky device to their leash will oftentimes be a dealbreaker and it would be easier to just grab some bags, treats, and anything else that an organization device would hold and put them in one's pockets.
Therefore, there needs to be a solution to ensure one does not run out of waste bags during a walk with their pet, while remaining small, light, and convenient.
The present invention can provide an apparatus which attaches to one's existing leash and holds two concurrent waste bag rolls. One waste bag roll is always in-use and is easy to pull bags off one at a time. When the in-use roll is empty, one can easily move on to using the next waste bag roll. The apparatus contains a quick and easy to operate opening mechanism to allow for roll replacement during a walk. The apparatus was designed to work with most waste bag rolls. The apparatus was designed to be as small as possible with minimal empty space to keep it lightweight and of minimal inconvenience to the user. Together, this allows for an apparatus which is lighter, smaller, and more convenient than in the prior art.
The device can include two halves containing space to hold two waste bag rolls. Each half can have small shafts onto which waste bag rolls can rotatably mount onto. The shafts allow for smooth operation of the in-use waste bag roll, along with consistent holding of the spare roll during use.
The device can include a large opening for the in-use waste bag roll. The opening is designed so that one's fingers can fit to pull out the first bag of the roll and for any bags that may get stuck during use. The opening is used to pull bags out of the apparatus one at a time. The device can include an opening for the spare waste bag roll, allowing an easy transition to the next roll.
The device can include a series of loops along the outside such that a strap can be attached to the device, which can then attach to one's existing leash. The device and strap can be configured to one's preference. The device and strap can be attached to a leash to allow for a long hanging application. The device and strap can instead be attached to a leash to allow for a tight hanging application. The device and strap can instead be attached to a leash with multiple points of contact allowing for a secure attachment that will not swing when walking. In particular embodiments this strap can be made of many types of materials such as cloth, leather, synthetic strapping, metal, plastic, rubber, silicone, and other similar materials.
In one embodiment the apparatus is comprised of two clamshells rotatably attached through the use of a hinge and shaft. In other embodiments, the apparatus may use other hinge designs such as a living hinge, a shaft directly on the halves, or other hinge designs known to those in the art. In some embodiments, a spring or similar mechanism can be added to the hinge to help in opening and closing of the apparatus.
In one embodiment the apparatus has a clip to secure the two halves closed. In one embodiment this clip is hidden inside of the device for aesthetic purposes. In other embodiments the clip can be on the outside, of a different size, of a different shape, and include other elements known to those in the art
In one embodiment, the two halves are not attached to one another permanently. The halves can be removed from one another and attached together through the use of clips, friction fits, clasps, straps, hooks, or other mechanisms known to those in the art.
In some embodiments, the outer housing can have protrusions that allow for used waste bags to be attached
In some embodiments, the parts can be made of rigid materials such as plastics, metals, and composites.
In some embodiments, the parts can be made of a combination of soft and rigid materials such as fabrics, cloth, silicone, and rubber.
The foregoing will be apparent from the following more particular description of example embodiments, as illustrated in the accompanying drawings in which like reference characters refer to the same parts throughout the different views. The drawings are not necessarily to scale, emphasis instead being placed upon illustrating embodiments.
