3. PREAMBLE TO THE DESCRIPTION:
The following specification particularly describes the invention and the manner in which it is to be formed.


Field of Invention:
The present invention relates to a multipurpose assembly for safe holding and handling of burnable material, more specifically, the patent relates to an assembly for handling mosquito coil.
Background of the Invention:
In India, according to 2001 census, about 72.2% of population lives in rural areas of India. Out of this, a large part is devoid of basic electrical supply. A large part of this population lives in darkness, devoid of basic electrical supply.
Additionally, Malaria has been a problem in India for centuries. Details of this disease can be found even in the ancient Indian medical literature like the 'Charaka Samhita'. In the 30's, there was no aspect of life in the country that was not affected by malaria. The economic loss due to the loss of man-days due to malaria was estimated to be at Rs.10,000 million per year in 1935. The annual incidence of malaria was estimated at around 75 million cases in 1953 with about 800,000 deaths annually. To combat this menace, the Govt, of India launched the National Malaria Control Program in April 1953. The program proved highly successful and within five years the incidence dropped to 2 million. Encouraged by this, the program was changed to a more ambitious National Malaria Eradication Program in 1958. By 1961 the incidence dropped to a mere 5000 cases a year. But since then the program suffered repeated set-backs due to technical, operational and administrative reasons and the cases started rising again, Malaria has now staged a dramatic comeback in India after its near eradication in the early and mid sixties.
The estimated economic loss due to malaria in India from 1990-1993 is $506.82 million to $630.82 million. India has spent up to 25% of its health budget on malaria control from 1977-1997, and starting in 1997, India planned to spend $40 million on malaria control, a 60% increase from the previous year. This expenditure is part of a five year program aimed to target 100 districts where 80% of all P. falciparum cases occur. 70-80% of the malaria control money in India is spent on insecticides.

One of the most viable protective means to repel mosquitoes is of course, to switch on an electrical mosquito repellent. But considering that about three-quarters of population stays in rural area devoid of electricity, this option cannot be used in villages, the obvious other choice is to use a mosquito coil. A conventional mosquito coil is usually made of mosquitocide incorporated in a combustible material and filler to form spiral shaped incense.
The coil has to be lit up at the open end for the mosquitocide incorporated in the coil clay to sublimate. The vapors hence produced are repulsive to mosquitoes. The fact that the coil needs to be ignited can lead to few dangers one such calamity whereby the naked coil lead to untimely demise of an individual has been reported in Times of India dated 18 March 2004, whereby the fire caused by a mosquito-repellent incense killed a woman and seriously injured her husband in Hafizbabanagar under Kanchanbagh police station limits. A probable way of preventing such incidence is to enclosing the burnable material in a container made of heat-resistant, non-inflammable material.
One such assembly has been discussed in US Patent No. US3796002 which teaches an assembly which is used as fumigator for mosquito coils comprising a can large enough to hold mosquito coil; a cup-shaped top lid and a cup-shaped inner-lid having a transverse surface provided with windows for diffusion of the fumes from a burning coil. The said assembly comprises of a resin-coated wire screen held in the top lid. The use of wire mesh complicates the process of manufacturing since the wire mesh has to be treated with resin or asbestos or any other heat resistant material to prevent it from burning or heating as well as from losing heat to surrounding, as the coil burns over the mesh. Further, since the coil is in complete contact with wire mesh there are chances that coil might snuff at sometime, leaving the rest of the coil unburnt.
US Patent No. US6061950 discloses an assembly for holding a burnable coil which comprises a base member having a spade extending upwards therefrom for supporting the coil and an array of non-metallic peaks positioned around the spade to support the coil in case it sags. The main disadvantage of presence of spike is that the assembly can not be used for placing coil pieces if need be for example a temporary relief from mosquitoes while at dinner or during camping, thereby making the product uneconomical for use.

Further the array of non-metallic peaks is unmovable. hence if small pieces of coil are to be used the support peaks, being fixed, will not be able to accommodate small pieces.
In view of the already presented prior art, the object of instant invention is to provide an improvised multipurpose assembly constructed from a heat-resistant and/or non-inflammable, moldable material for safe handling and holding of a burnable material.
In view of above stated prior art and the disadvantages enumerated thereby the instant invention provides for a multipurpose assembly for safe holding and handling of burnable material.
Summary of the Invention:
The object of this invention is to provide a multipurpose assembly for safe holding and handling of burnable material. The further object of the present invention is to provide a method for safe handling and holding of burnable material using the said assembly.
The further object of the invention is to provide an economical usage of the coil either as whole or part thereof, whereby the coil is supported on the adjustable movable assembly of plurality of metallic serrated blades, thereby increasing the economic appeal of the invention.
Still further object of invention is to provide a multipurpose assembly for use as a container for mosquito coils, candles, plants or any other form of decorative lighting so as to prevent any unwanted incidences hence reducing safety concerns.
Brief Description of Invention:
In one embodiment the invention provides a multipurpose assembly for holding a burnable material having a solid, encasable and enclosable base member made of heat resistant and/or non-inflammable material.
The said solid base member encases a plurality of serrated blades made of heat resistant and/or non-inflammable material having a length slightly lesser than the diameter of the solid base member, which are centrally held and horizontally placed by a flexible metallic
4

strip thereby dividing the blades in half length pieces which can be adjusted suitably to support any length of burnable materials. The said serrated blades are held at mid-point by a metallic strip whereby the strip is inserted in a centrally placed circular hole which permits a free horizontal movement of the blades about the center of the base member.
The said solid base member of the said multipurpose assembly encloses plurality of centrally held serrated blades. The blades are not held together by a central spike, but with a flexible metallic strip which does not form a spike. The advantage of not using a spike and instead placing the coil entirely on the serrated blades is that, the burnable material need not be in its entirety to be used. The flexible serrated strips can be adjusted as required to support the burnable material to be placed in the assembly.
In further embodiment, the said assembly comprises a top lid member which is also made of heat resistant and/or non-inflammable material. The said lid is slightly larger then the said solid base member. Further, the said lid has a step which laps over the upper edge of the said solid base member. Additionally, said top lid member has plurality of opening in ornamental shapes and sizes which can function as inlet and outlet for air and fumes respectively.
In preferred embodiment, the invention provides a multipurpose assembly for safe handling and holding of burnable material made of Tin-Steel or Tinplate which can be procured by already known processes as one described in JP 2007-239096 dated January 31, 2007 filed by Nippon Steel Corporation.
The said multipurpose assembly for safe handling and holding of burnable material comprises a circular, encasable, enclosable solid base member made of tin-steel sheet or tinplate or tin-free steel or mild steel.
The said solid base member may rest entirely on the ground or any flat surface which may or may not be heat-resistant, or can be supported by plurality of supporting protrusions either attached separately or introduced during the manufacturing process, that is, in-built.
The said multipurpose assembly for safe handling and holding of burnable material further comprises about 3-10 serrated blades, preferably 3-4, tin-steel or tinplate or tin-
5

free steel or mild steel, serrated blades which are of length, slightly less then the diameter of the solid base member enclosed in the solid base member so as to allow free movement of blades about the center of base member. The said serrated blades are held centrally using a flexible metallic strip placed at the exact mid-point of the length of the serrated blades.
The said serrated blades function as a support for the burnable material of any size or shape. The said serrated blades are flexible and hence, can be adjusted suitably to support the burnable material either as full or part thereof thereby eliminating the need of central spade to support the burnable material.
The said assembly for safe handling and holding of burnable material further comprises a top lid member, made of tinplate. The top lid member has a plurality of openings in ornamental shapes and sizes which can function as inlet and outlet for air and fumes, respectively.
In another embodiment, the multipurpose assembly of said invention is used as an enclosure for holding a burnable material selected from a set of cotton wicks either dipped in oil or ghee or liquid paraffin, wax or paraffin candles, diyas, decorative lighting material, camphor, etc.
The preferred burnable material as per instant invention is circular mosquito coil in full or part thereof.
In another form, the invention provides for a method of safe handling and holding of a burnable material wherein the burnable material is supported on or by the serrated blades, whereby the blades can be adjusted according to the length of the burnable material. The serrations prevent snuffing of the material. In case the pieces are smaller then the distance between the two blades; the blades, being flexible, can be adjusted to neatly hold the piece. The lit coil is placed inside the solid base and covered on top with the top lid member.
