This invention relates to a silkworm egg box. In India, about 33.55 crore layings of silkworm eggs (seed) are produced and supplied to the silkworm rearers each year. The eggs are supplied either on egg cards or in loose form. In advanced silk producing countries, like China and Japan, silkworm eggs are supplied to the rearers in loose form in a box. The egg box known in the art is made up of a wooden frame covered with muslin cloth. About 25,000 silkworm eggs are accomodated in each box. Silkworm seed is supplied in southern India in the form of eggs laid on thick paper sheets. In eastern parts of India, the eggs are distributed in loose form. Unfortunately, in many cases, the silkworm eggs are packed in small cloth bags and sold which is not safe for the eggs. This results in poor hatching or mortality of new born worms due to heaped condition. The scientifically designed loose egg boxes are either costly or not easily available. Further, the wooden egg boxes require skilled manpower to be manufactured, involve specialised wood cutting machines and are therefore more expensive. It is therefore an object of this invention to propose a silkworm egg box which is easier to manufacture. It is a further object of this invention to propose a silkworm egg box which is cheaper and safer and protects silkworm seed from shock and choking during transportation. A still further object of this invention is to propose a silkworm egg box which is prepared from easily available raw material and is biodegradable. These and other objects and advantages of the invention will be more apparent from the ensuing description. Thus according to this invention is provided a silkworm egg box comprising an upright rectangular frame, with a cloth stretched across the upper and lower surfaces thereof, the lower surface of the frame being supported by legs, a piece of paper fixed to the upper side of the frame and provided with a slit thereon. In accordance with this invention is provided a silkworm egg box which is manufactured from a thick paper board, also called pitch board which is softer than wood. The paper board is similar to that used for book binding and the material can easily be cut into strips in a paper trimmer, which can be assembled into the silkworm egg box using adhesive. The egg box primarily consists of a rectangular frame made of paper filling the box with silkworm seed and easy sealing. A semicircular slit is made on this portion of the muslin cloth through which the eggs are filled and sealed. The box provides an inner space of 448ØØ cubic mm good enough to comfortably accomodate about 25000 eggs of any commercial silkworm breed. The legs, besides providing rigid support for the frame, shall maintain the space between any two boxes to allow free passage of air ensuring better health for silkworm eggs. The invention will now be explained in greater detail with the help of the accompanying drawings wherein Fig.1. represents the front view of the silkworm egg box comprising the frame (2), with a muslin cloth (3), stretched across the upper and lower surface thereof, the lower surface of the frame being supported by four triangular legs (4) on four corners. A triangular piece of paper (5) is fixed on the muslin cloth on one corner of the box and provided with a slit (6) through which the silkworm eggs are filled into the box. The slit is covered by the flap (7). Fig.2 represents the back view of the silkworm egg box (1), showing the frame (2) and musl in cloth (3) stretched across the lower surface thereof. The triangular legs (4) are fixed to the four corners of the frame. By way of an example and without intending to imply any restriction on the scope of the invention is provided a silkworm egg box comprising of a frame made of paper (pitch) board and is 180 mm long, 90 mm wide and 4 mm thick. The width of the rim is 10 mm. A thin muslin cloth is stretched and pasted on both sides of the frame. The corners of the frame on its lower surface are supported by legs made of similar pitch board of 2! mm thickness and cut in the form of an equilateral right angled triangle with the equal sides measuring 20 mm. A triangular piece of paper is pasted to the muslin cloth on the upper side on one corner as shown in the figure to give a rigid support at the time of WE CLAIM: 1. A silkworm egg box (1). comprising an upright rectangular frame (2). made of wood with a cloth (3) stretched across the upper and lower surfaces thereof, the lower surface of the frame being supported by legs (4), a piece of paper (5) fixed to the upper side of the frame and provided with a sllt (6) thereon. 2. The silkworm egg box as claimed In claim 1 wherein sald cloth Is a muslin cloth. 3. The silkworm egg box as claimed In claim 1 wherein the frame Is made from paper board, preferably pitch board. 4. The silkworm egg box as claimed in claim 1 wherein the legs are rectangular in shape. 5. The silkworm egg box as claimed in claim 1 wherein the legs are in the shape of an equilateral right angled triangle. 6. The silkworm egg box as claimed in claim 1 wherein the legs are fixed to the corners of the lower side of the frame. 7. The silkworm egg box as claimed in claim 1 wherein the piece of paper is a triangular piece of paper. 8. The silkworm egg box as claimed in claim 1 wherein the piece of paper is fixed to one corner on the upper side of the frame. 9. The silkworm egg box as claimed in claim 1 wherein a semi-circular slit is provided on the paper and through the muslin cloth. A silkworm egg box (1). comprising an upright rectangular frame (2). made of wood with a cloth (3) stretched across the upper and lower surfaces thereof the lower surface of the frame being supported by legs (4), a piece of paper (5) fixed to the upper side of the frame end provided with a sllt (6) thereon.
