Definitions

• the present invention relates to a twin walled, insulated compost receptacle comprising at least two inter-connectable side wall elements, a bottom and a lid.
• a twin walled, insulated compost receptacle comprising at least two inter-connectable side wall elements, a bottom and a lid
• the receptacle is characterized in that at least one preferably all side wall elements are equipped with, towards the inside of the receptacle, open ventilation channels which extend vertically from the bottom along at least the main part of the height of the receptacle
• the channels are at the bottom connected to a through going air duct, wherein the composting rate can be accelerated by an increased air supply to the compost material in the receptacle through the channels.
• the bottom is preferably concave with a raised outer edge in which the air duct at least partly is formed. It is suitable to form the air duct in the upper part of the raised outer boarder Occasionally a part of the air duct is composed of a notch in the lower edge of the side wall elements
• the air duct can also be provided with vertical ribs.
• the bottom of the receptacle is suitably perforated, also on the raised outer edge.
• the bottom on the lower part of the raised outer boarder is provided with notches, inwardly directed channels or the like, intended to via the perforation lead air from below to the compost material in the receptacle
• the air supply is by the design according to the present invention extremely good, since air is provided from below via the bottom as well as from the sides through the vertical channels
• the compost receptacle can be manufactured from a wide variety of plastic materials such as for example polyethylene, polypropylene and polyurethane.
• plastic materials such as for example polyethylene, polypropylene and polyurethane.
• the walls of the compost receptacle, which as mentioned above are twin walled are advantageously manufactured by blow moulding, even though other methods such as injection moulding can be utilized
• All side wall elements are at least in the main identical, normally fully identical Thereby the advantage is achieved that only one mould will be required for the manufacturing of the side wall elements, which will make the production cheaper
• the side wall elements can be provided with integrated locking means, used for joining the side wall elements, whereby the handling of separate assembly details is avoided
• the side wall elements are usually loosely placed on top of the bottom between ribs, pegs or the like shaped on the bottom When assembling the receptacle the side wall elements are placed next to each other on top of the bottom and are coupled together with the integrated locking means
• One side wall element is normally detached and removed when the receptacle is to be emptied, whereupon the completely composed material can be removed with a pitchfork or the like
• One or more side wall elements can also be provided with an emptying hatch, whereby the emptying of cause takes place through this and not by removal of a side wall element
• the lid is mostly twin walled to give a good heat insulation It can be provided with one or two so called folding lines so that it will be flexible and folded up and down one half at the time
• the lid can be fixed towards the opening of the receptacle in different ways It is, inter alia, possible to have a snap-in lock where snap-in lips in the opening of the receptacle or on the lid are snapped together with a complementary notch in the lid or the opening of the receptacle respectively Alternatively the lid can be attached by a bayonet joint
• the lid can also, if desired, be provided with an extra heat insulation in the same way as the side wall elements as mentioned above.
• Figure 1 shows the compost receptacle in perspective seen aslant from below
• figure 2 shows the receptacle aslant from above
• Figure 3 shows in perspective the outside of a side wall element of the compost receptacle
• figure 4 shows in perspective the inside of the element
• Figure 5 shows schematically in perspective the inside of the receptacle with only one side wall element assembled
• Figures 6 and 7 show in perspective the bottom of the receptacle seen from below and above respectively
• Figures 8 and 9 show in perspective from below respectively above one embodiment of a lid to the receptacle
• Figure 10 shows in perspective a section of two adjacent side wall elements with an integrated locking means. The perforation of the bottom of the receptacle is only schematically shown in the figures
• Figure 1 shows, according to above, one embodiment of a compost receptacle 1 consisting of four twin walled inter-connectable side wall elements 2, a bottom 3 and a lid 4
• All side wall elements 2 are provided with, towards the inside of receptacle directed, open ventilation channels 5 (fig. 5) which extends vertically from the bottom 3 along the main part of the height of the receptacle 1 .
• the channels 5 are at the bottom connected to a through going air duct 6 (fig. 5).
• the bottom 3 is concave with a raised outer boarder 7 (figures 5 and 7) in which the air duct 6 is formed in the upper part Vertical ribs 8 are formed in bottom of the air duct 6.
• the bottom 3 is on the lower part of the raised outer boarder 7 provided with notches and channels 9 intended to lead air from below to the compost material in the receptacle 1 via the perforation in the bottom
• the compost receptacle 1 is assembled by placing the four side wall elements next to each other on recesses 12 in the bottom 3.
• the bottom 3 is also provided with upwards directed pegs 1 3 , which will be located on the outside of the lower outer edge of the side wall elements 2
• the pegs 13 will thereby contribute to a stable assembly of the receptacle 1
• the side wall elements 2 are at their vertical edges 14 suitably provided with matching flanges 1 7, 1 8 and a number of protruding lugs 1 5, 1 6 which fits together and contribute to a stable assembly.
• the lid can be provided with one or two so called folding lines 1 1 so that it becomes foldable and can be folded up one half at the time
