Description

CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is a continuation-in-part of U.S. patent application Ser. No. 10/872,924, filed Jun. 21, 2004, which claims the benefit of U.S. Provisional Patent Application No. 60/482,358, filed Jun. 24, 2003, both of which are incorporated herein by reference in their entireties.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The following invention relates to refuse containers or trash receptacles and apparatus and methods for dispensing trash bags and lining refuse containers with trash bags.

2. Description of the Related Art

Refuse containers of all types are commonly lined with trash bags. The trash bags have many benefits including keeping the surface of the refuse container separated from trash within the bag, to maintain cleanness of the container, and being sealable and removable to transport and store trash.

One inconvenient task associated with lining refuse containers with trash bags is changing the lining, or trash bag, out. Usually this involves removing the prior full trash bag, then obtaining a new trash bag from a separate storage location, placing it within the refuse container and manually expanding the trash bag to ensure that it is fully open and lined against the trash container, then knotting the trash bag to try and hold it in place.

ATICO INTERNATIONAL, U.S.A., Inc., distributes a “nesting trash bag system” wherein a plurality of bags are nested together. The bags are disposed, or nested, sequentially within one another such that the outside surface of the first bag in the nest, nests against the inside surface of the second bag in the nest, and so on, including as many as more than twenty (20) bags. All of the bags can thus be placed in a trash container at one time with the inside surface of the first bag being exposed to receive refuse. After each bag is full, it can be pulled out and away from the inside surface of the next bag so that the next bag can receive refuse. One drawback with the “nesting trash bag system” is that the unit of nested bags is thick and must be disposed within the trash container to line its inside surface. In smaller trash containers this negates the benefit of the nesting trash bag system where a tradeoff is less capacity for the trash container. Furthermore, prior systems lacked a convenient way to retain the trash bags in place once expanded within the refuse container. There is a need for a more convenient and space efficient way of replacing trash bags within the trash containers.

BRIEF SUMMARY OF THE INVENTION

In some embodiments of the present invention a refuse container is provided having a dispensing aperture for dispensing bags. The dispensing aperture is oriented on a bottom inside surface of the refuse container. A tray for holding bags can be disposed beneath the dispensing aperture and the bags are arranged in a coil within the tray. Thus, the bags can be pulled through the dispensing aperture to line an inside surface of the refuse container. The bags can also be connected to one another in a coil with perforated zones. A gap can be provided in the perforated zones to assist a user in separating the bags, that is, for example, the user can insert a finger through the gap to help separate the bags.

Further embodiments of the present invention also comprise a raised wall that surrounds the dispensing aperture for helping to prevent liquid accumulation from flowing through the dispensing aperture. In addition, the dispensing aperture can also comprise a sealing element.

The refuse container can also have handles with gripping members that can be used to grip a bag in place after it is pulled through the dispensing aperture to line an inside of the refuse container.

In some embodiments, a trash bag gripper is provided that can be a tab or strip, which is removably attachable to a sidewall of the refuse container. The tab or strip can have a receded portion with a wide entryway that narrows before leading to an expanded region to allow a portion of the bag to be retained in the expanded region.

DETAILED DESCRIPTION OF THE INVENTION

In the following description, certain specific details are set forth in order to provide a thorough understanding of various embodiments of the invention. However, upon reviewing this disclosure one skilled in the art will understand that the invention may be practiced without many of these details. In other instances, well known structures associated with refuse containers and trash bags have not been described in detail to avoid unnecessarily obscuring the descriptions of the embodiments of the invention.

The term “trash bag” as used herein refers to any type of liner or bag used to line refuse containers or collect refuse within a refuse container, regardless of the shape, size or material of the liner or bag. The term “refuse,” as used herein, is intended to include all types of waste, recyclables and any other material that is commonly disposed of within a bin or container. The term “refuse container” refers to any and all types of containers, bins, and receptacles configured to receive, store, transfer, hold, or contain refuse, regardless of the shape, size or material of the refuse container. The terms above are to be construed as has been defined unless the context indicates otherwise.

In some embodiments of the invention a refuse container assembly 1 is provided, as illustrated in FIG. 1. The refuse container assembly can comprise a refuse container 2 having handles 4 with sidewalls 6 and a bottom surface 8. Also, the refuse container 2 can have an extended bottom section 9 for receiving a holding member 10, as discussed, infra.

A holding member 10 (illustrated as a tray in the embodiments of FIGS. 1, 2 and 4) for holding trash bags can be disposed below the bottom surface 8, within the extended bottom section 9. The holding member 10 can have a plurality of compartments 12, 14, 16 defined by compartment sidewalls 20, with each compartment being capable of storing a separate item. A first compartment 12 can be configured for storing a plurality of trash bags. A plurality of trash bags are illustrated in FIG. 2 as being arranged in a coil 18 and disposed within the first compartment 12. The trash bags 18′ can each be pulled from the coil 18 through a dispensing aperture 22 of the bottom surface 8 to line the refuse container, as discussed below. The remaining compartments 14, 16 can be used to store items such as, for example, ties or air fresheners, or canisters containing air freshening substances or cleaning substances. Also, the holding member 10 can have a handle 11 for selectively sliding the holding member between an open and closed position as discussed below.

The holding member 10 can be slidably coupled to the refuse container as illustrated in FIGS. 1 and 2. In some embodiments, the holding member 10 can also be completely removed from the refuse container 2, as shown in FIG. 3E. When the holding member is coupled to the refuse container 2, it can be slidable in the direction of arrow “A” in FIG. 1, from a closed position, as illustrated in FIG. 1, to an open position, as illustrated in FIG. 2. Conversely, the holding member 10 can slide in the direction of arrow “B” in FIG. 2, from the open position, as illustrated in FIG. 2, to a closed position, as illustrated in FIG. 1.

As best seen in FIGS. 1, 2, and 3B, in some embodiments of the present invention, the bottom surface 8 has a dispensing aperture 22. Also, a raised lip 24 can be formed on the bottom surface 8 surrounding the dispensing aperture 22. A user of the present invention can pull a trash bag 18′ from the plurality of trash bags 18 disposed beneath the bottom surface 8, through the dispensing aperture 22, into the refuse container 2, to line the refuse container 2. This is best seen in FIGS. 4, 5, 6, and 7. That is, FIG. 4 shows a trash bag 18′ beginning to be pulled through the dispensing aperture 22 by a user (not shown in the FIGs), generally in the direction of arrow “C,” into the refuse container 2. The trash bag 18′ is being pulled from a coil 18 of trash bags 18′, such as that the coil 18 illustrated in FIG. 2. Each of the trash bags 18′ is in a folded or compact position when it is part of the coil 18. FIG. 5 shows the trash bag 18′ further pulled, or extended, generally in the directions of arrows “D,” into the refuse container 2, with the trash bag 18′ beginning to be expanded from its compact position within the coil 18. FIG. 6 shows the trash bag further pulled, or extended from its position in FIG. 5, with the mouth or opening 26 almost fully open and with a top end portion 19″ of the trash bag 18′ being pulled generally in the direction of arrows “E” over the top of the sidewalls 6 of the refuse container 2. FIG. 7 shows the trash bag 18′ with a top end portion 19″ thereof pulled over the sidewalls 6 of the refuse container 2, with the trash bag 18′ lining the container and ready to receive refuse.

The raised lip 24 of the refuse container assembly 1 has an outside wall 28 that rises above the bottom surface 8 of the refuse container 2, as best seen in FIGS. 1 and 4. The outside wall 28 of the raised lip 24 can help block liquid from entering the dispensing aperture 22 when liquid leaks out of a trash bag 18′ containing refuse and accumulates at the bottom of the refuse container 2.

As discussed, supra, in some embodiments of the present invention, the trash bags 18′ are arranged in a coil 18, the coil having a substantially circular profile. See FIG. 2 and FIG. 3G. Furthermore, the coil 18 can be packaged in a packaging box 30, as best seen in FIG. 3G. The coil 18 can lay flat in the packaging box 30 with a diameter of the coil 18 being disposed laterally within the packaging box 30 such that an axis of the coil 18 is disposed vertically. The thickness “x” of the coil 18 can therefore also be measured vertically, as shown in FIG. 3G & 3I. The packaging box 30 can be any shape.

The coil 18 can comprise trash bags 18′ releasably attached to one another in end to end configuration, with bottom end portions 19′ of the trash bags 18′ attached to top end portions 19″, to form a chain of trash bags 18′ connected by tearable attachments. See FIG. 31. The trash bag chain of connected trash bags 18′ are arranged in the coil 18. As will be appreciated by one skilled in the art after reviewing the present disclosure, the tearable attachment between the trash bags 18′ can be formed by attaching the trash bags 18′ to one another with a perforated zone 32. The perforated zone 32 provides an attachment portion that is weaker than other portions of the trash bags 18′ to allow the trash bags 18′ to be torn away from one another without ripping another portion of the trash bags 18′ that could cause a leak.

The thickness “x” of the coil 18 can be less than about four (4) inches in some embodiments. In other embodiments it is about three (3) inches or less than three (3) inches. The thickness “x” can also be greater than four (4) inches and in some embodiments it is five (5) inches and in other embodiments it is six (6) inches. In each of the embodiments of the coil 18, a desired thickness of the coil 18 can be attained by folding the trash bags 18′, or the chain of trash bags 18′, laterally prior to forming the trash bags 18′ into the coil 18. For example, the trash bags 18′ can be folded multiple times laterally along the fold lines 34 illustrated in FIG. 3J, to achieve “x” thickness of the coil 18. The thickness “x” can be substantially equal to the distance between the fold lines 34.

FIG. 3K illustrates an embodiment of the chain of trash bags 18′ of the present invention wherein the trash bags 18′ are connected by perforated sections 32′, with lateral space 32″ between the perforated sections 32′ to allow a user to more easily separate the trash bags 18′ from one another, in comparison with the perforated zone 32 connection between the trash bags 18′ of FIG. 3J.

As discussed, supra, the trash bags 18′ can be arranged in a coil 18 and packed within a packaging box 30. The packaging box 30 can also have a cover 36. See FIG. 3H. The cover 36 can be a tear-away cover connected to the packaging box 30, such that the packaging box 30 can be sold with a coil 18 disposed therein, and with a cover 36 attached. In some embodiments, a purchaser of the packaging box 30 tears away the cover 36 and places the packaging box 30 within an embodiment of holding member 10′, as illustrated in FIG. 3F. The holding member 10′ illustrated in FIG. 3F has retaining members 20′, instead of sidewalls 20, for retaining a packaging box 30 received in the holding member 10′. In other embodiments, the packaging box 30 can be received in the holding member 10 between sidewalls 20 of the holding member 10 of FIG. 3E (i.e. within the first compartment 12.). Also, in further embodiments, the coil 18 can be removed from the packaging box 30 and inserted in the first compartment 12 of the holding member 10 of FIGS. 2 and 3E, for use with the refuse container assembly 1. For each of the embodiments in FIGS. 2, 3E, and 3F, the holding member 10, 10′ and the trash bags 18′ can be dispensed through the dispensing aperture 22, as illustrated in FIGS. 4, 5, 6 and 7.

In yet further embodiments of the refuse container assembly 1, the refuse container 2 has removable, or detachable, handles 4′ having interior surfaces with gripping members 4″, as best seen in FIGS. 8 and 9. A mating surface 5 of the refuse container 2 also has gripping members or apertures 4″′, the mating surface being configured to mate against the interior surfaces of the detachable handles that themselves can have insertion members 4″ or other gripping members. The insertion members 4″ can be inserted into the apertures 4″′. when they are attached to the refuse container 2. The detachable handles 4′ are also configured to be releasably attachable to the refuse container 2 with a portion of a trash bag 18 between the detachable handles 4′ and the mating surface 5. For example, the detachable handles 4′ can be detached prior to pulling the top end portion 19″ of a trash bag 18′ over a top of the sidewall 6 of the refuse container 2, See FIG. 9A. The top end portion 19″ of the trash bag 18 can then lay over the gripping members 4″′ (or apertures) of the mating surface 5. The detachable handles 4′ can then be attached to the mating surface 5 with the top end portion 19″ of the trash bag 18 disposed between the interior surface of the handles 4′ and the mating surface 5 such that the gripping members 4″, 4″′ grip and retain the trash bag 18 in position, as illustrated in FIG. 11.

In other embodiments of the present invention, safety cords 40 are provided, each having one end fixedly attached to the refuse container 2 and another end fixedly attached to a detachable handle 4′. This can prevent a detachable handle 4′ from being lost after it is detached. See FIG. 10 & FIG. 11.

As will be appreciated by one skilled in the art after reviewing the present disclosure, the detachable handles 4′ with gripping members 4″ can also be connected to the refuse container 2 by connection members 7, 7″ such as those illustrated in FIG. 12 and FIG. 13. The connection members 7, 7″ can be configured to allow the detachable handles 4′ to pivot away from the mating surface 5 when detached therefrom. In some embodiments, the connection members 7″ are single section members that can be flexible, such as those illustrated in FIG. 12. In other embodiments, the connections members 7 are dual section members (as illustrated in FIG. 13), with pivoting joints 7′ that allow the detachable handles 4′ to be lifted upward away from the mating surface 5 in the direction generally represented by arrows “G,” then pivoted away from the mating surface 5 in the direction generally represented by arrows “F.”

In still further embodiments of the present invention a sealing element 42 is disposed over the dispensing aperture 22, as best seen in FIG. 3C and FIG. 3D. The sealing element 42 can be comprised of flexible flaps that form a seal against a trash bag 18′ partially pulled through the aperture 22. See FIG. 3D. The sealing element 42 can help prevent liquid from draining through the dispensing aperture 22 when a leak develops in a trash bag 18′ within the refuse container.

In other embodiments of the present invention, such as that shown in FIG. 14, a refuse container 102 is provided with a holding member 110 for receiving laterally placed trash bag coils 118. A trash bag coil 118 can be placed within a compartment 120, and additional trash bag coils 118 can be stored in storage areas 114.

As shown in FIGS. 14 & 15, the holding member 110 can slide below a bottom surface 108 of the refuse container 102 below an aperture 122 to align the trash bag coil 118 in compartment 120 with the aperture 122. As can be seen in FIG. 16, the trash bags 117 can then be unwound from the trash bag coil 118 by being pulled through aperture 122, on an as-needed basis, and expanded and until a top end portion 119 of an expanded trash bag 117 is folder over top edge portion of the refuse container 102.

In some embodiments of the present invention, the first trash bag in the trash bag coil 118 can have a pull tab 116 for a user to pull the first trash bag up and through aperture 122.

When a trash bag coil 118 is exhausted, a user can slide the holding member 110 out from under a bottom surface 108 of the refuse contain 102 in the direction of arrow “I”, and place a new trash bag coil 118 in compartment 120, then slide the holding member 110 back under the bottom surface 108 in the direction of arrow “H.”

In a further embodiment of the present invention, as best seen in FIGS. 17a-19, a removable trash bag gripper 130 can be attached to a side portion of the refuse container 102 for use in gripping and holding trash bags in place once expanded. The trash bag gripper 130, as shown in FIG. 17b, can be a strip or tab with an inwardly receding portion 131 with a wide entryway 131a that narrows inwardly 131b before widening into an expanded region 131c, for gripping trash bags in the expanded region. The trash bag gripper can be made of, without limitation, flexible plastic material.

As shown in FIGS. 17b & 17c, a holding strip 132 can be formed on a surface of the refuse container for use in removably attaching the trash bag gripper 130 to the refuse container 102. As best seen in FIG. 17c, the trash bag gripper 130 can have a locking protrusion 134 formed thereon, which can be mated within a recess 136 formed on the refuse container 102 to removably lock the trash bag gripper against the refuse contain when the trash bag gripper is inserted under the holding strip 132 by being slid in the direction of arrow “J,” until it is locked in place as shown in FIG. 17a.

As shown in FIG. 18, a top end portion of a trash bag 117 can be manually attached to the trash bag gripper 130 to hold the trash bag in a substantially stationary position extended and folded over an edge of the refuse container 102.

Referring to FIG. 19, in some embodiments of the present invention, the trash bags 117, 18′ can be connected to one another with perforated zone 141 having a gap 140 therewithin. The gap 140 can be used to help separate the trash bags 117, such as by placing a finger through the gap 140, when puling the trash bags 117, 18′ through aperture 22, 122 of the refuse container 2, 102.
