Description
1 Regulation 3.2 AUSTRALIA Patents Act 1990 Complete Specification For The Invention Entitled: IN-GROUND COMPOSTING DEVICE The invention is described in the following statement: 2 Field of the Invention [1] The present invention relates to a composting device. Specifically, the present invention relates to an in-ground composting device. Background of the Invention [2] Conventional composting devices typically take the form of a bin or other container into which suitable composting material is placed. The composting material is left to decay in the bin to form compost. Conditions within the bin need to be managed to ensure that compost is formed efficiently, and at a suitable quality. Worms, additional water, organic waste, dry material, and the like are often added to achieve or maintain optimal conditions within the bin. [3] The compost formed in in the bins provide much needed nutrients for plants. Accordingly, composting is seen as an economical and eco-friendly way of disposing of waste, improving soil quality, and enhancing plant growth. [4] Conventional compost bins tend to require a dedicated space as the decaying compost material releases an unpleasant odour. The work required to manage and use the compost also typically means that the area around the compost bin is dirty, and may attract unwanted insects and other vermin. The presence of helpful worms in the bin is also an issue that many people find mildly uncomfortable or repulsive. Manual labour is also required to periodically transfer the compost from the bin to the soil. [5] The disclosed invention seeks to overcome or substantially ameliorate at least some of the deficiencies of conventional composting devices, or to at least provide an alternative. [6] It is to be understood that, if any prior art information is referred to herein, such reference does not constitute an admission that the information forms part of the common general knowledge in the art, in Australia or any other country.

Description of Embodiments [51] It should be noted in the following description that like or the same reference numerals in different embodiments denote the same or similar features. [52] Figure 1 shows a composting assembly 10 according to a first preferred embodiment of the present invention. The composting assembly 10 comprises a composting device 100 (in the form of a tube 100), a cap 110 and a plunger 130. [53] The tube 100 comprises a hollow tubular body 102 having open ends 104. The body is perforated with apertures 120 which are spaced along the length and circumference of the body 102. The tube 100 is constructed from a biodegradable material such as cardboard, wood pulp, or bioplastics. In the embodiment, the tube 100 is 30 cm long. [54] The cap 110 is sized to fit over and close one of the ends 104 of the tube 100. The cap comprises a planar upper plate 112 and a peripheral skirt 114 which extends downwardly from a periphery of the upper plate 112. The cap 110 is made from steel mesh. [55] The plunger 130 comprises an elongated handle 132 and a pushing plate 134 at one end of the elongated handle 132. The plunger 130 in use assists with the filling of the tube 100. [56] Referring to Fig. 2, the composting device tube 100 is shown with the cap 110 placed over one end 104 of the tube 100. The cap 110 is configured to prevent animals from entering the tube 100 in use. In the example shown, the cap 110 loosely covers an end 104 of the tube 100. The cap 110 can however be adapted such that the skirt 114 tightly engages the body 102 of the tube 100. [57] Referring to Fig. 3, the inside of the tube 100 defines an internal space 300 for receiving composting material. The apertures 120 connect the internal space 300 inside the tube 100 to the environment outside of the tube 100. The apertures 120 are sized to allow fluids, bacteria, soil, worms, and other substances to transit between the internal space 300 and the environment outside of the tube 100. The plunger 130 is sized to fit within the diameter of the internal space 300 and is used to pat down compost material in the tube 100 and facilitate filling of the tube 100. [58] Referring to Fig. 4, use of the composting device 100 is shown. In use, the tube 100 is buried in a vertical orientation, typically in a garden, with one end 104 thereof substantially aligned with the ground level. The user digs a hole 30 cm deep and then places the tube 100 within the hole. Soil/earth is then placed to surround the tube 100. The internal space 300 is kept empty at this stage for receiving composting material. Unlike conventional composting 6 devices, the composting device 100 of the present invention is placed and used while in the ground, preferably in vicinity of the plants that the compost from the composting device 10 is intended to feed. [59] Composting material such as food scraps, organic waste, and the like are placed in the internal space 300 of the tube 100 while the tube 100 remains in the ground. The plunger 130 is used to compress the composting material in the internal space 300 to maximise the amount of composting material that can be placed within the internal space 300. The cap 110 is then used to cover the open upper end 104 of the tube 100. The peripheral skirt 114 is buried into the ground to avoid easy removal of the cap 110 by animals and rodents. The cap 110 prevents vermin and cockroaches from entering the tube 100. [60] The internal space 300 can be filled over a number of days or weeks, as food scrap for example is generated in the household. The user will place the food scrap in the internal space 300 as available and replace the cap 110 in position each time. Also, as compost breaks down within the internal space 300, additional compost material can be placed therein. [61] As compost is formed, the compost and nutrients from the compost seep through the apertures 120 into the surrounding soil and enrich the soil. The apertures 120 also attract worms to the internal space 300 and allow the worms to feed on the composting material, further assisting with the composting process. By attracting worms to the composting device 100, the soil around the composting device 10 is also naturally enriched and aerated by the presence of the worms. Hence, the composting device 10 provides a two level effect of firstly providing nutrients from the composting material to the soil, and secondly attracting worms to the soil which themselves naturally enrich the soil. [62] Maintenance of good composting conditions within the composting device 100 is made easier by storing the composting device 100 in the ground. The presence of rain, natural sunlight, and the typically moist conditions of sub-surface soil are conducive to the composting process. Additional effort to create and maintain good composting conditions is therefore reduced. Moreover, the storing of the composting device 10 in the ground and in vicinity of the plants greatly reduces, and in many cases completely removes, the work needed to transfer compost from a bin to the plants. Compost formed by the composting device 10 enters the soil through the apertures 120 and the open ended bottom of the tube 100. Accordingly, compost and nutrients are continuously being fed to the neighbouring soil. [63] As mentioned, the tube 100 is constructed of a biodegradable material such as cardboard, wood pulp, or bioplastics. By constructing the tube 100 of a biodegradable material, the composting device 10 itself eventually feeds the environment it is in, and minimizes its eco footprint. The tube 100 is also preferably made from a material which retains 7 moisture which assists in the composting process. The tube 100 is constructed to completely biodegrade within 1 to 12 months, and preferably within 3 to 4 months. The cap 110 can be reused as required. [64] As mentioned above, the apertures 120 are sized to be large enough to allow fluids, bacteria, soil, worms, and other substances to transit between the internal space 300 and the environment outside of the tube 100. The apertures 120 are also sized to be small enough to prevent the compost material and large amounts of the generated compost to wash away through the apertures 120 in the event of heavy rains. Whilst the escape of small amounts of the generated compost is desirable, as it assists with the spreading of compost and nutrients into the neighbouring soil, the escape of large amounts of compost is wasteful and slows down the composting process. Further, the escape of composting material can have a polluting effect and also lead to the attraction of unwanted vermin. The apertures 120 preferably have a diameter of between 5mm and 20mm. [65] The cap 110 being made from mesh allows the internal space 300 to breathe as well as allowing moisture within the internal space 300 which assists in the composting process. [66] Referring to Fig. 5, multiple composting devices 100 may be distributed around a garden or pot. Preferably, each composting device 100 is positioned in the vicinity of a group of plants so that the compost and nutrients created by the composting device 100 can automatically seep from the apertures 120 of the tube 100 into the soil surrounding the plants. A grid-like pattern of composting devices 100 may be implanted into a garden to provide a steady and even supply of compost and nutrients to all plants in the garden. [67] In a second alternative embodiment, the tube 100 is constructed from a natural but non-biodegradable material such as clay, terracotta, or stone. The composting device 100 of the second embodiment is a permanent structure stored in the ground, and may be better suited over the first embodiment when long term and regular use is desired. The cap 110 may also take a more ornamental shape and design, and may also be constructed from the same non-biodegradable material as the tube 100, to improve the aesthetics of the composting device 10 as a whole. In one example of the second embodiment, the cap 110 has the shape of a garden gnome. [68] Referring to Figures 6 and 7, three tubes 1 00a, 1 00b, 1 00c and three caps 11 Oa, 11 Ob, 11 Oc of different sizes are illustrated. A composting kit with various tube sizes may be used to better suit gardens/pots of different sizes, type of composting material predominantly used, type of soil that the composting devices 100 will be stored in, type of plant to be fed, and the like. Each tube 1 00a, 1 00b, 1 00c is between 15 cm and 45 cm long, and between 10 cm and 20 cm in diameter. Preferably each tube 100a, 100b, 100c is around 30 cm long and around 8 15 cm in diameter. The length and diameter of each tube 1 00a, 1 00b, 100c involves a trade off between the amount of composting material and compost that can be stored, and a size of a hole that is required to be dug in the ground to hold the composting device 10. The composting devices 100 are ideally placed before laying garden soil material to assist with quick installation thereof. [69] The three tubes 100a, 100b, 100c of Fig. 6 are preferably packaged together as a kit, with one tube stored inside another in a nested manner as shown in Fig. 7. The three tubes 100a, 100b, 100c thus have incrementally decreasing diameters. Packaging the kit of tubes 100a, 100b, 100c in this nested manner provides users with greater flexibility of use, and significantly reduces storage and shipping costs. [70] Referring to Figs. 8A and 8B, a composting kit 800 containing a three tube package and three caps is shown assembled for shipping, and packed in a shipping container 810. At least two of the caps 11 Oa and 11 Ob have different diameter skirts 114 so that they can be nested with each other and placed over one end 104 of the nested tubes 100. The third cap 1 00c can then be placed below the nested tubes 100. [71] The composting device 10 of the present invention provides an eco-friendly way of disposing of waste and of providing nutrients to plants. Maintenance of the composting device 10 is simplified compared to conventional composting devices, with the maintenance of optimal conditions for the composting device being largely controlled by nature. Any dirt, waste, and insects normally associated with composting devices is limited to the ground in which the composting device 10 is stored, and predominantly underground and out of sight. [72] The composting device 10 of the present invention provides a continuous feed of compost and nutrients to the surrounding soil, and requires little additional work from a user to enrich the soil. The additional effect of the composting device 10 naturally attracting worms to its location further provides an additional level of soil enrichment not provided by conventional out-of-ground composting devices. [73] Whilst preferred embodiments of the present invention have been described, it will be apparent to skilled persons that modifications can be made to the embodiments described. For example, the tube 100 may be square, rectangular, oval, or polygonal. The tube may also taper inwards or outwards. The caps 110 may be colour coded to indicate the type of composting material contained therein, last use, or which day of the week it is to be filled. These and other modifications are included within the scope of the disclosed invention. [74] In another possible modification, the lower end of the tube can be fully or partially closed, for example by having a solid closing panel or a perforated panel integrally or 9 attachable to the tube lower end. Also, the cap can be pivotably attached to the upper end of the tube and lockable thereto in the closed position. [75] The composting device can be a hollow container of any desired shape, such as a hollow cube or a hollow prism.
