Waste collection and disposal apparatus

Abstract

An apparatus for collection and disposal of waste, comprising a container with a lid fastened by hermetic closure elements, with a piston inside that can slide and forms a hermetic chamber; and waste compaction and fluid discharge elements, that comprise first air and liquid suction elements connected to a space between a detachable collecting flexible container arranged inside the hermetic chamber, and the walls of the hermetic chamber, and second air and liquid suction elements connected to the inside of the flexible container.

Description

[0001] The present invention relates to an apparatus for collection and disposal of dry waste, wet waste and the like, particularly but not exclusively for the domestic environment. [0002] The present invention is applied also in the management of industrial dirty waste and refuse and in many other fields, such as the medical and sanitary field, the biochemical field, and the like. BACKGROUND OF THE INVENTION [0003] As it is known, the sorted collection of the above cited waste is currently mandatory as a consequence of European Economic Community directives regarding the need to manage waste by aiming for its recovery and recycling. [0004] From the hygiene standpoint, the worst waste is the waste generally termed “wet”, which includes the discarded parts of food such as meat, vegetables, fruit, fish, et cetera. [0005] Such wet waste, if not disposed rapidly, ferments inside the bag in which it is deposited and becomes the source of bad odors and a strong attraction for insects and ...

AI Technical Summary

Benefits of technology

[0019] Within this aim, an object of the present invention is to provide an apparatus that is capable of eliminating the liquids and odors from the waste collected therein.

[0021] Another object of the present invention is to provide an apparatus that is capable of completely hiding the waste from the user's sight.

[0022] A further object of the present invention is to provide an apparatus whose dimensions are such that it can be installed easily in a domestic environment without particular problems in finding sufficient space.

[0023] A still further object of the present invention is to provide an apparatus for waste collection and disposal that can be installed even more conveniently in biochemical laboratories, in surgeries and in industrial buildings and other similar environments dedicated to industrial production.

[0024] Another object of the present invention is to provide an apparatus that is structurally simple and can be manufactured at low cost with known systems and technologies.

Problems solved by technology

Such wet waste, if not disposed rapidly, ferments inside the bag in which it is deposited and becomes the source of bad odors and a strong attraction for insects and small animals of various kinds that are generally unwanted in a domestic environment.

Moreover, some “wet” waste can release liquids which, if the waste containment bag is torn, may spill into the environment when the bag is extracted from the container in which it is accommodated, with great inconvenience both because of the cleaning needed to restore the propriety of the environment and because of the unpleasant odor that said liquids may emit.

Therefore, both due to the difficulty of separating “wet” and “dry” waste but also due to laziness or distraction of a user, “wet” waste often ends up being deposited partly or fully also in the container designed for “dry” waste.

Such device, although being capable of reducing the waste to particles small enough to be disposed without problems by a generic domestic sewage system, introduces in the street sewage system a load that cannot be withstood by said sewage system and in the long term damages it and forces frequent maintenance.

However, this second type of apparatus has a significant bulk and is therefore difficult to install for example in a home kitchen.

Moreover, said apparatus, in addition to being unable to control the release of unwanted odors, has the additional drawback of never completely removing the waste from the user's sight.
