Abstract

The invention relates to a watertight big bag for a deep refuse container, especially for organic waste. Prior art knows solutions such as hard plastic containers used as a removable inner container, which can be emptied. Unfortunately, those hard plastic containers can leak, which liquid eventually begin to stink and can freeze the hard plastic container into the bottom of the refuse container, which may break the plastic container when lifted. A big bag for a refùse container according to the present invention comprises an outer sack having a closable/openable bottom part, an inner sack disposed into the outer sack, and means for closing/opening the bottom part of the outer sack. The inner sack comprises an extension section, which extends below the bottom part of the outer sack so that the bottom part of the inner sack is attachable to the big bag.

Background technologyBackground technology

Domestic households have been taught to sort their garbage e.g. organic, paper, metal and glass waste from the other waste. In urban and suburban areas, the sorted waste is usually collected into large containers, the emptying of which is normally provided by municipality or outsourced private companies. It is advantageous to collect organic waste into large, semi or fully underground containers, because the emptying can thus be performed more rarely. Also the unpleasant odor of the organic waste may disturb less the surroundings, because the waste can lie below the ground level, which normally has lower temperature than surroundings above the ground level, even in summer time.Domestic households have been taught to sort their garbage e.g. organic, paper, metal and glass waste from the other waste.

Also, the unpleasant odor of organic waste may disturb the surroundings, because the waste can lie below the ground level, which normally has lower temperatures than surroundings above the ground level, even in summer time.

The emptying process of semi or fully underground refuse containers for organic waste comprises problems, because the container is normally fixed to its place. Prior art knows solutions such as hard plastic containers used as a removable inner container, which can be emptied.The emptying process of semi or fully underground refuse containers for organic waste involves problems, because the container is normally fixed to its place. Prior art knows solutions such as hard plastic containers used as a removable inner container, which can be emptied.

Unfortunately, those hard plastic containers are expensive to manufacture and can be difficult to use. In addition, they are usually not watertight, which causes problems. Liquid contained in organic waste can leak from the plastic container into the bottom of the refuse container, which liquid eventually begin to stink and, if the ambient temperature is below zero degrees, can freeze the hard plastic container into the bottom of the refuse container. This may cause the hard plastic container to break when lifted from the refuse container and the contents of it to fall into the refuse container. This causes a burdensome and time consuming cleaning process of the organic waste container and the hard plastic container has to be replaced, which naturally causes extra costs. US 5,238,356 disclose a method of storing and collecting waste employing periodically emptied waste containers. Waste is stored in a storage space included in a waste container, namely in a reusable subcontainer such as a sack, which is picked up from the storage space during the collection and unloaded. A waste container for carrying out the method is further disclosed which comprises a storage space for storing waste. The storage space is provided with a reusable subcontainer, such as a sack, for storing waste, and the subcontainer is removable from the storage space. The bottom of the subcontainer is provided with an openable and closable hole for emptying the contents of the subcontainer.Unfortunately, those hard plastic containers are expensive to manufacture and can be difficult to use.
