DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

[0020] The following detailed description of the invention refers to the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings and the following description to refer to the same and like parts. Dimensions of certain parts shown in the drawings may have been modified and/or exaggerated for the purposes of clarity or illustration.

[0021] In brief, the invention is a pot for composting which is placed in a hole in the ground allowing worms from the surrounding soil to enter the pot and nutrient rich liquid to exit. A ventilated lid is fitted to keep vermin and dogs at bay. The lid may also be inverted and filled with soil for propagating seedlings. A clear dome may be fitted over the lid to act as a glasshouse.

[0022] The invention thus comprises three components: a pot 10 as shown in figure 1A and 1 B; a lid 30 as shown in figures 2A and 2B; and a dome 50 as shown figure 3. As shown in figure 4A, the lid 30 may be fitted to the pot 10 to act just as a lid, or as shown in figure 4B the lid 30 may be fitted to the pot 10 to act as a seedling tray. Figure 5 further shows the dome 50 fitted to the pot 10 when the lid 30 is acting as a seedling tray.

[0023] Details of the pot 10 can be seen in figure 1 A where it is viewed from above and figure 1 B where it is viewed from below. The pot 10 is shaped similarly to a conventional plant pot, having a frustoconical body 12, bottom 14 and rim 18. The body 12 has a number of apertures 13 which allow worms to enter the pot from the surrounding soil. The bottom 14 incorporates a mesh 16 allowing liquid, as produced from the decomposition of organic material, to leave the pot. The rim 18 includes peg holes 24 to facilitate securing the pot to the ground as shown in figure 6B. The rim also includes tab holes 20 which provide access to locking slots 22 used for securing the lid 30 and dome 50 to the pot.

[0024] The lid 30 is shown in detail in figures 2A and 2B. The lid 30 comprises sidewall 32, bottom 36 and rim 40. The lid 30 and sidewall 32 respectively incorporate apertures 34 and mesh 38 to provide ventilation for the pot 10 to which the lid is fitted. Small insects may also pass through the mesh and help in the decomposition by for example laying maggots in the organic material. When the lid 30 is used as a seedling tray the mesh 38 provides drainage for the soil in the lid. In the centre of the lid 30 there is a handle 46 to facilitate rotating the lid to engage or disengage it with the pot 10. The handle 46 is in the shape of a cross in order that it can either be grasped or have fingers inserted into it to facilitate rotation of the lid 30. The rim 40 provides rigidity and includes locking tabs 42 with nodules 44 for securing the lid 30 to a pot 10. [0025] The dome 50 is shown in figure 3 and is similar in shape to an inverted plant pot. The dome 50 comprises frustoconical body 52 with top 56 and rim 58 to provide rigidity. Optionally the body 52 incorporates strengthening ribs 54. The ribs 54 also provide grip to aid rotating the dome 50 for engagement to or disengagement from the pot 10. The rim 58 has attached locking tabs 60 with nodules 62 for securing the dome 50 to a pot 10. The locking tabs 60 also include peg holes 64 allowing the dome to be secured to the ground independently of a pot. To act as a glasshouse, the dome 50 is made from a clear plastic material.

[0026] The lid 30 may be attached to the pot as shown in either figure 4A or 4B. In both cases the locking tabs 42 of the lid 30 are placed into the tab holes 20 of the pot 10 and the lid is rotated relative to the pot such that the locking tabs 42 engage with the locking slots 22 of the pot. Nodules 44 on the locking tabs 42 engage with locking holes 23 in the pot to detachably secure the lid and pot together. The pot and lid are held together securely enough to prevent separation by the wind or a dog, but are readily separable by a person if desired.

[0027] The dome 50 may also be attached to the pot as shown in figure 5. The locking tabs 60 of the dome 50 are placed into the tab holes 20 of the pot 10 and the dome is rotated relative to the pot such that the locking tabs 60 engage with the locking slots 22 of the pot. Nodules 62 on the locking tabs engage with locking holes 23 in the pot to detachably secure the dome and pot together. The dome and pot are held together securely enough to prevent separation by the wind or a dog, but are readily separable by a person if desired.

[0028] Figures 6A - 6D demonstrate how the invention is used for composting. The pot 10 is placed in a hole in the ground 70 as shown in figure 6A. The pot 10 is then secured to the ground with the aid of pegs 72 passing through peg holes 24 as shown in figure 6B. As shown in figure 6C the pot 10 is then filled with organic waste 74 for composting. Finally the lid 30 is fitted and secured to the pot 10 by a rotational motion as shown in figure 6D. The organic waste will slowly decompose in the pot releasing nutrients to the surrounding soil. Additional waste can be easily added after removing the lid by simply rotating it. The invention can be left in place indefinitely, perhaps being emptied of residual material once per year.

[0029] The invention may also be used for propagating seedlings as shown in figures 7A and 7B. In this case the lid 30 is inverted so that it may be filled with soil 76 and have seedlings 78 planted therein. The dome 78 may be fitted to act as a glass house. The material decomposing in the pot beneath the lid (not visible in these figures) provides heat and moisture and thus a micro-environment conducive to plant growth.

[0030] The reader will now appreciate the benefits of the invention, providing a simple and effective means for composting without the ardour of traditional means an also providing a useful means for propagating seedlings.

[0031] Further advantages and improvements may very well be made to the present invention without deviating from its scope. Although the invention has been shown and described in what is conceived to be the most practical and preferred embodiment, it is recognized that departures may be made therefrom within the scope and spirit of the invention, which is not to be limited to the details disclosed herein but is to be accorded the full scope of the claims so as to embrace any and all equivalent devices and apparatus. Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of the common general knowledge in this field.

[0032] In the summary of the invention, except where the context requires otherwise due to express language or necessary implication, the word "comprising" is used in the sense of "including", i.e. the features specified may be associated with further features in various embodiments of the invention.
