CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority of U.S. Provisional Patent Application No. 61/340,638, entitled “Improved Refuse Container”, filed Mar. 16, 2010, which is hereby incorporated by reference in its entirety.
BACKGROUND Refuse barrels or other refuse containers of various size and shape are used widely to collect rubbish, trash and garbage before being picked up by a disposal service. Such containers are typically placed outdoors in commercial or residential areas where the odors of discarded food products frequently attract various animals, including vermin and pests.
Animals frequently gain access to the contents of some such containers, even in urban and suburban areas, by, for example, toppling them and causing the covers to pop open and the contents to spill. The resulting mess frequently attracts more animals and pests. Since these containers, or at least their covers, are commonly made of plastic, animals may also gain access to the contents by chewing holes through the container walls or covers and thus damaging them. U.S. Pat. No. 4,944,393, which is hereby incorporated by reference in its entirety, discloses the use of a trash bag with a quantity of animal repellent secured to the interior of the bag. During use, the repellent is typically in a bag full of refuse. Placing the repellent in the plastic trash bag limits the amount of the repellent that reaches the exterior of the refuse container. Since the mass of refuse placed within the bag is typically much greater than the mass of repellent, any repellent scent that escapes the trash bag is necessarily diluted by other scents in the bag and is, therefore, less effective. Placing such repellents or deodorants inside trash bags may result in them being covered by refuse when the container is partially or completely full. Under such circumstances, the effectiveness of repellents or deodorants may be hindered or eliminated completely.
Such bags are typically shipped and sold in rolls containing many bags. The mass of repellent tucked in folded bags would interfere with the process of rolling them up. Since the particular repellent used with such bags must be preselected, they cannot be tailored to specific applications or locations by using the most effective repellent for a particular location. Repellents prepacked with bags may also lose potency over time and may, therefore, have a limited shelf life.
Wild animals foraging for food in refuse containers in populated areas may lose their fear of humans, which can be problematic. It can lead to increased attacks on people, children, and pets as well as injury to wild animals. It can also lead to the spread of diseases, such as rabies.
SUMMARY OF INVENTION Animals are typically attracted to the odor of discarded food. Since refuse containers are typically not airtight, sufficient such odors frequently escape from refuse containers to attract animals.
Various repellents can be used to drive away animals that forage for food in refuse containers. These repellents are typically specific to an animal or group of animals. Some repellents include the scent of a predator that the animal has a natural fear of. For example, products by Shake-Away in Hamden, Conn., can be used to repel various types of animals such as raccoons, skunks and squirrels. Alternatively, products such as deodorants can be used to mask the odors of discarded food so that they no longer attract animals. Products such as mothballs may be used to mask the smell of discarded food products.
It is an object of this invention to secure a receptacle such as, for example, a box, bag or pouch to a refuse container. The receptacle can be used to securely hold repellents or deodorants. The receptacle may be attached permanently or temporarily to the refuse container. A refuse container typically comprises a substantially cylindrical body, a barrel, and a lid or cover, although containers of other shapes may also be used. The lid of a refuse container may be separate from or attached to the body of the container. Alternatively a receptacle may be attached to buildings, fences or posts. It is preferred that the receptacle have openings that allow scent emanating from materials placed in the receptacle to diffuse out while limiting access, to the contents of the receptacle, by young children, pets, or wild animals. The receptacle may be attached to the interior of the refuse container or to its exterior. It is preferred that the receptacle openings be exposed to the exterior of the refuse container so that the scent of the repellent is dispersed preferentially outside the refuse container compared to the scent of the contents of the refuse container. The receptacle may be incorporated during the manufacturing process into the structure of the refuse container or cover, for example, by molding the receptacle as a part of such components. Alternatively, these receptacles may be attached permanently by devices such, for example, as screws or rivets or attached so that they may be easily removed, for example, by hooks, ties, bolts, snap connectors, straps, belts, buttons, Velcro or zippers. Alternatively the receptacle may be attached to various sections of the refuse container or other objects by using adhesives or sticky tape.
It is another object of this invention to configure a receptacle to have an adjustable cover that can be used to vary the size of the receptacle opening in order to regulate the rate at which the scent is allowed to emanate from the receptacle. The adjustable cover may also be used to close off the receptacle when desired.
It is a further object of this invention to configure a receptacle with an opening designed so that it can be conveniently emptied, cleaned and refilled with repellent or deodorant.
It is yet another object of this invention that a receptacle is configured to store deodorants or repellents in one or more of several forms, for example, powders, solids, shavings, or liquids. Sponges, cotton balls or other absorbent materials impregnated with various repellents or deodorizers may also be placed in such a receptacle.
It is yet another object of this invention to configure a receptacle, for holding repellents or deodorants, that can be attached or otherwise secured to other structures, such as walls, fences, or posts, for example in the vicinity of where the refuse containers are kept.
It is a further object of this invention that a receptacle for holding a repellent or deodorant is sealed in a discardable receptacle. Such a receptacle is pre-filled with an amount of repellent or deodorant and is configured to be conveniently attachable to any desired surface or object including the interior or exterior of a refuse container.
It is preferred that receptacles be configured to be water resistant and resistant to weather including rain, snow, direct sunshine, heat and wind.
