Description

FIELD

This disclosure relates generally to waste disposal containers.

BACKGROUND

If consumers are able to keep their garbage cans outside their home, many dispose of pet waste or other biomass or malodorous waste in garbage cans. Some consumers are unable to store garbage cans outside of their homes (e.g., due to condo/apartment or home owner association restrictions). In those cases, consumers may keep garbage cans in their garage or inside their dwelling unit. Over time, the trapped (removed pet) waste in the garbage cans emits an unpleasant odor.

SUMMARY

In some embodiments, a container comprises a plurality of outer side walls connected to form a tubular structure. One or more permeable inner walls are near respective ones of the plurality of outer walls, defining a respective space between each inner wall and its respective adjacent outer wall. A lid (which can be vented or non-permeable) is provided for covering a top opening of the tubular structure. A removable base is provided at or near a bottom opening of the tubular structure.

In some embodiments, a container comprises a tubular structure having a non-permeable outer surface, the tubular structure having a tapered inner structure at a bottom thereof, at least one mount attached to the outer surface for attaching the container to a structure with the container located above a ground surface; a lid for covering a top opening of the tubular structure; and a removable base at or near a bottom opening of the tubular structure.

In some embodiments, a method comprises: storing waste in a container having non-permeable outer walls, a lid, at least one permeable inner wall and a removable base; continuously ventilating the container through the inner wall; and removing the base to empty the waste from a bottom of the container.

In the description, relative terms such as “lower,” “upper,” “horizontal,” “vertical,”, “above,” “below,” “up,” “down,” “top” and “bottom” as well as derivative thereof (e.g., “horizontally,” “downwardly,” “upwardly,” etc.) should be construed to refer to the orientation as then described or as shown in the drawing under discussion. These relative terms are for convenience of description and do not require that the apparatus be constructed or operated in a particular orientation. Terms concerning attachments, coupling and the like, such as “connected” and “interconnected,” refer to a relationship wherein structures are secured or attached to one another either directly or indirectly through intervening structures, as well as both movable or rigid attachments or relationships, unless expressly described otherwise.

This disclosure provides a single or double-walled container 100 or “garbage can” to temporarily hold bags of malodorous waste until the waste can be disposed of into a larger container. The can 100 may be mounted on a wall or on a stand or other raised man made or natural structures (ex. tree) or, alternatively, the can may rest on the ground. The container 100 can also dispense waste bags and hold pet accessories.

FIGS. 1-12 show an exemplary container 100 according to some embodiments. In some embodiments, the container 100 comprises 4 parts: (1) the body or container tubular structure 111, (2) the lid 116, (3) the base 120 and (4) the mounting components 130. The first component of the design is a tubular structure 111, which can be a single or double-walled body. The body can be formed from any of a variety of materials, such as plastic, metal or a metal coated with a corrosion resistant material. The exterior walls 110a-110d of the body 111 are solid while the interior walls 112a, 112b are vented, creating at least one space 114a, 114b between the inner 112a, 112b and outer walls 110a-110d. The vents 119 (perforations or slots) also provide fluid drainage. In some embodiments, the spaces 114a, 114b are separated from each other. In other embodiments (not shown), the spaces 114a, 114b are connected to each other, by connecting passages (not shown) or additional spaces (not shown) between the outer walls 110a, 110b and additional ventilated inner walls (not shown).

The container 100 has an opening 118 to place bags of waste into the container at/near the upper end that can be covered by an attached or unattached lid 116. In some embodiments, the lid is attached. The lid can be attached by a variety of mechanisms, such as a hinge, hook and loop fasteners, tabs with matching slots, latches, or the like or alternatively rest on the upper surface of the container with or without a tapered interference fit or locking securement mechanism (not shown). 116h. In some embodiments, the hinge 116h comprises two interlocking components connected by a removable pin, so the lid 116 can be removed from the body 111. In some embodiments, the lid 116 overhangs and/or curves over the outer walls 110a-110d of the tubular container body 111. In some embodiments, the container's outer wall 110a has a cut-out 113 at or near the lower end on the front 110a or side 110b or 110d. The cutout 113 is configured to receive a slidably removable base 120.

Inside some embodiments of the container 100, are cut-out slots 124 for a removable, base 120 to slide in or out of the container 100. In some embodiments, the base 230 is vented. In some embodiments, the base 230 can have slots or perforations (221, FIG. 24). In other embodiments, the base 120 can comprise a mesh or screen 121 (FIG. 12). The perforations, slots or mesh provide ventilation and liquid drainage. In other embodiments, the base is non-vented and non-permeable. When the base 120 slides out, the pet waste drops through the opening 122 in the lower part of the container 100. In some embodiments, one or more tapered interior walls 140, 142 facilitate waste sliding out the bottom 122 of the container 100 towards the center of the container's dimensions. In some embodiments, the base 120 is solid (non-permeable material without slots, perforations or other openings) and is removable for emptying waste from the bottom of the container 100.

In some embodiments, on the exterior of the container near the lower end 122 are protrusions, knobs or hangers 126 to hang a bag 128 below the container 100 during the emptying process. Two or more of the sides 110a-110d of the container 100 can have design elements such as hooks, pockets, webbing, platforms and/or ledges to hold pet accessories. An area 136, 138 of the exterior part of one of the outside walls 110a may contain a dispenser 132, 1334 for (removed pet) waste bags.

The lid 116 protects the contents from rain and limits odors and insect infestation. The lid may be vented or non-permeable. A latch (not shown) may secure the lid 116 to the body 111. The container 100 can be mounted on a wall (not shown) or other raised man-made or natural structure (e.g., a tree or post). In other embodiments, the container 100 is mounted with an accessory stand, which can be a separate unit. FIG. 34 is a side view of a system 300 including a post 152, on which two of the containers 100 are mounted back-to-back; FIG. 35 is a top plan view of a system 400 including a post 154, on which four of the containers 100 are mounted. While the mounting brackets 130 remain fixed to the wall, post or stand, the container 100 can be removed, cleaned and reassembled back to the mounting brackets 130.

In the vented embodiment, the vented inner walls 112a, 112b (double wall construction) allow the waste to dry out and partially vent from underneath to minimize odors. The opening 118 at the upper end facilitates loading waste into the container 100. In some embodiments, the lid 116 overhangs the body 111 of the container to prevent any odors from leaking out and also to prevent any rainwater entering if the container is kept outside. In some embodiments, a latch (not shown) or other securement device prevents the lid 116 from blowing open if outdoor conditions are windy when the device is mounted outside. In some embodiments, the vented base 120 facilitates aeration. The slots 124 allow the base 120 to slide in and out of the cutout to facilitate emptying the container 100. In some embodiments, the tapered interior walls 140, 142 (FIG. 8) facilitate waste dropping out the middle of the container 100. In other embodiments, the tapered interior walls 240 facilitate waste dropping out the front back or sides (FIGS. 16-18). The exterior storage design and bag dispenser 132, 134 provide convenience for managing pet accessories. The mounting brackets 130 and/or stand 152 or 154 allow users who do not wish to affix the body 111 to a wall to still use the system. A Microban coating, if present, provides microbial resistance. The outer walls 110a-110d can have a variety of finishes which can include a standard exterior finish and color or a finish pre-primed and ready to paint as well as various surface textures.

In some embodiments, the tapered interior walls 140, 142 facilitate waste drop, and odor management inserts 145 manage odors. The device 100 can easily be removed from the post 152, 154 (by disconnecting the mounting brackets 130) and hosed off for cleaning, then re-mounted.

Some embodiments include the double walled body, the lid, and the base. Other components can be added.

The lid 116 can either be attached or unattached. The lid attachment mechanism 116h can vary in design. In some embodiments (not shown), the base 120 can be double-walled with perforations. In other embodiments, the base 120 has a single wall that slides in and out of a cut-out in the body 111. In some embodiments, the base 120 is solid (i.e., without perforations, slots or other openings). In some embodiments, instead of sliding in and out of slots 124 on the container 100, the base 120 can also be attached to the body and open or close. In some embodiments, the exterior of the body or lid may contain accessory hooks, knobs or protrusions 126. Some embodiments include hooks on the lid 116. Other embodiments omit the hooks.

In some embodiments, an all plastic construction can withstand the elements and prevent rusting. In some embodiments, the exterior of the container has slots 136, 138 configured to receive pre-loaded cartridges 132, 134 of eco-friendly pet waste bags, or a refillable bag dispenser.

In some embodiments, the body 111 can be provided in multiple sizes (lengths), with a variety of finishes (such as, but not limited to, plastic or pre-primed for painting) and textures. Some embodiments have an antimicrobial coating such as Microban or the like.

The system can also include scented and/or odor neutralizing bags 128 in the dispensers 132, 134, oxo- or biodegradable and/or earth friendly bags and/or a place to affix or insert an odor masking or neutralizing component 145 (FIGS. 21A-22C, 25 and 26).

In some embodiments, the device 100 is mountable, e.g., for personal use. Other embodiments for commercial designs can be made of metal (e.g., steel or aluminum) and mounted on a pole or raised man-made or natural structures, and may or may not include the odor management features 144, 145. In other embodiments, a user digs a hole beneath the container, and uses a material (e.g., sawdust, kitty litter, etc.) to manage pet waste as a composting material. In some embodiments, the plastic construction improves durability under different weather conditions and facilitates cleaning. The design provides a more sanitary way to handle pet or other odorous waste at home.

Although examples above use the container 100 to store pet waste, the container 100 can be used to store any malodorous contents, such as food waste.

The base 120 is able to withstand the downward pressure of the accumulated pet waste resting on it without warping. The entire system is able to withstand extreme weather and hot/cold temperatures. The mounting brackets 130 securely hold the device 100.

In some embodiments, the lid 633 has a compartment 616 with a door 614, as shown in FIG. 43. The compartment 616 can be accessed (from outside the container) by opening the door 614, without opening the lid 633 of the container 600. The compartment 616 can store a variety of accessories, such as disposable bags, or deodorant in a variety of forms (e.g., cake, pellets, powder, gel, liquid or aerosol). In the embodiment of FIG. 43, the compartment 616 has one or more mounting brackets 637 (FIG. 49) for rotatably mounting spools 618 for holding and dispensing disposable sanitary plastic or paper bags. In some embodiments, the bags are plastic, may be biodegradable, durable and leak proof. For example, the bags can be made of polyethylene, polypropylene or polystyrene, treated with an additive to shorten the life of the plastic (e.g., “D2W” additive, sold by Symphony Environmental Technologies, PLC, Hertfordshire, UK or Totally Degradable Plastic Additives (“TDPA®”) sold by EPI Environmental Products Inc.).

FIGS. 48, 48A and 48B show an example of a spool 618 for holding a roll of bags 627. Each spool 618 has end caps 623, 625 that mount to the brackets (not shown) on each side of the compartment 616. In some embodiments, the door 614 has one or more slots (not shown), positioned to allow the bags 627 to be fed through the slot while the door 614 is closed. In other embodiments, the door is without slots, and the user opens the door each time a bag is to be removed. In some embodiments, the brackets are different from each other, and the end caps 623, 625 of the central spools 618 are different from each other, with the end caps 623, 625 configured to mate with respective brackets on each side of the spool 618. The spool can include ornamental features, such as, but not limited to, the circular protuberance 619 on end cap 623 and/or the triangular protuberance 621 on end cap 625. In some embodiments, each spool 618 can have a respectively different type of bag (e.g., small and large sizes, scented and unscented bags, regular and extra strength bags, etc. The brackets can have bearings to allow rotation of the spools 618 while mounted in the brackets, for dispensing the bags.

In some embodiments, the spool 618 is a unitary body, and the brackets (not shown) include bearings (not shown) to allow the spool to rotate about its axis while loading or dispensing bags. The bearings allow the central spool to rotate relative to the spool 618 to rotate, for loading or dispensing bags. The bags are loaded or dispensed by rotating the spool.

In other embodiments (not shown), the spool 618 has internal bearings, and the brackets (not shown) have fixed openings. The bearings in the spool allow the central spool to rotate relative to the end caps 623, 625, the round protuberance 629 and the triangular protuberance 621, for loading or dispensing bags.

In some embodiments, the spool is sold fully loaded with plastic bags 627. In other embodiments, the user can manually load bags on an the spool 618, either by rotating the spool within the compartment 616, or by removing the spool from the compartment and loading the bags outside of the compartment.

FIGS. 44 and 45 show the inner container 620. The inner container 620 has a receptacle 624 and a rim 622. The rim 622 is sized and shaped to seat snugly between the top edge of the outer container 602 and the bottom of the lid 633, as shown in FIG. 43. The height of each face of the inner container 620 is less than or equal to a height of the corresponding side faces 630, 631, 632 and 635 of the outer container 602, so the inner container 620 fits inside the outer container 602 with the lid 633 closed and the closure 606 engaged. In some embodiments, the inner container 620 is shorter than the outer container 602, so the inner container 620 hangs from the top edge of the outer container 602. In some embodiments, the inner container 620 is sized so there is about a 1″ (2.5 cm) channel 660 (e.g., from 0.75″ to 1.25″) between the inner container 620 and outer container 602, on the side faces and the bottom face, as shown in FIG. 49. This channel 660 ventilates the inner container 620, and allows the odors from the inner container to descend to the openings 611 in the bottom of the outer container 602.

The inner container 620 has at least one vented face 624. In some embodiments, as shown in FIG. 45, the side face 624 has a plurality of vents 626. The vents 626 can be circular holes, or the vents can have an ornamental shape, such as a shape of a dog's paw, as shown. The vents can be on one or more of the front, back, left, right or bottom sides. The vents 626 can be located on part or all of the vented side(s). For example, FIG. 45 shows an inner container 620 having vents 626 on the left and right side faces.

In some embodiments, the vented sides 624, 634, or 652 on either or both of the inner container 620 and/or the outer container 602 are covered with mesh, netting or screen cloth 629 (FIG. 49) to prevent insects from entering the containers. In some embodiments, the screen cloth 629 can be stainless steel, fiberglass or extruded vinyl coated polyester screening, or ultraviolet (UV) blocking screen or other materials. The screen cloth 629 can be placed on the inside and/or outside of the faces of the inner container 620 and/or outer container 602. In operation, the container 600 or 650 can be located on a floor. The height of the lid 633 can be conveniently set at from about 15″ to about 30″ (38 cm to 76 cm) above the floor. In some embodiments, the height of the lid 633 is from about 18″ to about 22″ (45 cm to 56 cm) above the floor. At this height, with the lid 633 open, the user can conveniently lift and remove a filled bag 627 inside the container and install a new empty bag 627 in its place. The open end of the bag can be wrapped around the rim 622 of the inner container 620. Periodically, the user can also remove the inner container 620 from the outer container for cleaning. The user can grip the rim 622 of the inner container 620, and lift the inner container 620 out from the outer container 602 for cleaning.

In various embodiments, the container 600 can have an odor masking or absorbing insert (e.g., a charcoal filter) inside the outer container 602 or outside of the inner container 620 (between the outer and inner containers), inside the compartment 616, under the compartment 616 or under the lid. In some embodiments, either or both of the inner and outer containers 620, 602 includes a plastic additive to minimize odor.

FIGS. 50 and 51 show an example of a mount 661 that can be used for mounting the container 600 above a floor or other surface. The mounting mechanism can comprise a single fixation point or multiple fixation points. For example, the mounting bracket 661 includes a plate 664 that is mounted to a wall 669, pole, or other vertical surface by two standoffs 662. The standoffs 662 can be attached to the wall, pole the like or by any of a variety of fasteners including, but not limited to, nails, screws, bolts or the like. The back face 635 of the container 600 has a complementary receptacle 665 configured to receive the plate 664. For example, the receptacle 665 can be a recess having a channel or groove on at least two sides that is sized and shaped to receive the plate 664. In some embodiments, the plate 664 has a friction fit in the channel. The mounting bracket 661 can have a mechanism to secure or lock the bracket 661 and receptacle 665 together. The recess 665 can extend all the way to the bottom of the container 600, so the receptacle 665 can slide down over the plate (for a fixed plate) or the plate can slide up into the receptacle as shown (for a plate mounted to a pole, before the pole is implanted on the ground or mounted on a stand). Although the plate 664 is shown as rectangular, the plate can have any of a variety of shapes including, but not limited to, a circle or triangle.

Although the subject matter has been described in terms of exemplary embodiments, it is not limited thereto. Rather, the appended claims should be construed broadly, to include other variants and embodiments, which may be made by those skilled in the art.
