Multi-Sectioned Improved Air Supply Compost Container

The invention relates to a compost container consisting of a number of ring-shaped container sections made of a plastic material and capable of being assembled as well as a ventilated base-plate and a lid.

An object of the present invention is to provide a compost container having an improved air supply to the container's internal composting space.

This purpose is achieved through a compost container characterized by a ventilation partition formed from a part of the base-plate's outermost edge laid against the inside of the wall of the bottom-most container section thereby forming a ventilation column therebetween to supply air to the container's internal composting space.

The invention is described hereafter as a discussion of a practical model with reference to the attached drawings of which:

The present invention relates to a compost container (1) consisting of a number of ring-shaped container sections (2-5) made of a plastic material capable of being coupled and assembled as a unit, a ventilating base-plate (7) with pervading openings (6), a lid (8) with ventilation openings (9), and a ventilation section (10) which facilitates air supply (11) to the container's internal composting space (12). More particularly, a ventilation column (17) is formed between a wall section (15) of the bottom-most container section (2) and an air-permeable ventilation partition (16) formed from a part of the base-plate's outermost edge (13).

As shown in FIGS. 7 and 7a, the base-plate (7) has as an outer edge a column-shaped channel (18) which extends around the base-plate's (7) entire circumference and into which it is intended that the bottom-most container section's (2) wall section (15) be placed. This, together with a rise (19) in the base-plate's outermost edge facilitates effective air supply to the compost container (1). For the purpose of ventilation, a number of ventilation holes (20) are found in the rise (19) in the base-plate's outermost edge and extend from the outside of the container into the ventilation column (17).

The compost container (1) has in particular a number of ventilation partitions (16) distributed along the base-plate's outermost edge (14) as an incorporated part of said edge (14). The ventilation partitions (16) extend essentially vertically, meeting the inside wall of said container section (2) at the ventilation partition's respectively upper end (16A) where holes (52) are found which lead into the container's internal composting space (12).

The compost container (1) consists of a number of ring-shaped container sections (2-5) which have outwardly inclined walls (22-25), relative to the respective upper edges (2A, 3A, 4A, 5A) and the edges (2A, 3B, 3A, 4B, 4A, 5B, 5A) intended for coupling. In one embodiment, the edges can be stair-stepped and, respectively, angled out and have openings (26) that take, for example, self-threading screws (27).

In one embodiment, the lid (8) has fasteners in the form of a snap-lock (28) which makes it possible to fasten the lid (8) to the uppermost container section (5), yet allow it to be turned, while secured to the container (1). In this manner, air supply can be either increased or decreased into the container's composting space (12) via air vents (29) in the lid. Depending on the position of the air vents (29) in the lid (9), the ventilation openings (9A) are exposed to a greater or lesser extent. A number of the ventilation openings are found in the upper edge of the uppermost container section (5).

A compost container (1) of the sort the invention herein refers to can be transported packed together as, for example, is shown in FIG. 8, by setting the different container sections (3-5) one inside the other, including the lid (8), within the bottom-most section (2). All these are then set on top of a base-plate (7) section. The container sections (2-5) have inclined side walls and can be unpacked, screwed together with screws (27) and placed on a site intended for the assembled compost container. As shown in FIG. 1, vertically moveable doors (48, 49), that normally cover over the openings (50, 51) designed for emptying the container (1) and that are situated opposite to each other in the bottom-most section (2) can, when composted material has settled in the bottom of the container (1), be opened by sliding them upwards when the user wants to empty the container (1). Effective ventilation of the container (1) is now achieved thanks to the invention, which is not limited to the drawings shown or the descriptions of the practical model herein, but can be varied within the frame of the patent claims without abandoning the invention's idea.
