FIELD OF THE INVENTION

[001] Embodiments of the present invention generally relates to storage technologies. More particularly the invention relates to a tank for liquid storage and a system for manufacturing the tank using rotational moulding.

BACKGROUND OF THE INVENTION

[002] Manufacturing goods in a centralized system is cost effective due to availability of infrastructure under one roof and united work force. However, transportation of goods results in increase of the overall price of the goods when they reach their destinations. The centralized manufacturing system is feasible where the goods are easy to transport. In order to reduce the price, packaging is made in a certain way to accommodate a large amount of goods. The goods are arranged and piled up to take up lesser space so that more of the goods can be transported. However, in case of transportation of hollow tanks, the utilization of space is highly inefficient. A lot of space is taken by empty space. Therefore, influence of cost of transportation on product prices is high for the hollow tanks. Hence the leaders cannot take the best advantage of the economies of scale and cost advantage goes to regional player. For manufacturing of the hollow tanks, multiple techs are used including roto-moulding technique is used. With roto- moulded technology, products are made in one hollow piece. Same goes for roto- moulded liquid tank as well. Also, traditionally made tanks are made hollow using one piece moulding which make them impossible to stack and does not allow transporting them efficiently which increases the freight cost considerably and makes local player cost efficient and mass production and distribution in a centralized scenario becomes tough. Therefore, the companies cannot take advantage of better technology and economies and other advantages of big scale production.

[003] Therefore, there is a need for a stackable tank for storage and a system for manufacturing the tank using rotational moulding to curb the transportation cost and address other defects in prior art. OBJECT OF THE INVENTION

[004] An object of the present invention is to provide a system for manufacturing a tank in 2 or more parts using rotational moulding.

[031] Referring to the drawings, figure 1 illustrates a system (100) for rotational moulding of a tank (not shown in this figure), in accordance with an embodiment of the present invention. As shown in figure 1 , the system (100) comprises a mould having a first part (102), a second part (104), a separator (106), and one or more pins (110). In accordance with an embodiment of the present invention, the first part (102) and the second part (104) of the mould may be made for moulding a polymeric part. The mould may be made of, but not limited to hardened or prehardened steel, aluminium, and/or beryllium-copper alloy, titanium, titanium alloy or any other metal or composite material.

[032] In a preferred embodiment, the moulding may be rotational moulding. The rotational moulding involves a heated hollow mould which is filled with a charge or shot weight of material. It is then slowly rotated, causing the softened material to disperse and stick to the walls of the mould. However, it may be appreciated by a skilled addressee that the moulding may be selected from a group comprising extrusion moulding, compression moulding, blow moulding, injection moulding and rotational moulding as well.

[033] Figure 2 illustrates a cross-sectional view of the system (100), in accordance with an embodiment of the present invention. As in accordance with an embodiment of the present invention, the first part (102) may be adapted to shape a top dome (103). Further, the second part (104) may be adapted to form a tapered bottom (105) having a predetermined shape (not shown in this figure). The predetermined shape may be selected from a group comprising a tapered cylindrical shape, a tapered polygonal shape having sides, each making an angle (A) with flat bottom (109) of the second part (104) of the mould. In accordance with an embodiment of the present invention, walls of the second part (104) of the mould may form an angle (A) in range of 90.5° to 135° with bottom (109) of the mould.

[034] Figure 3 illustrates the tank, in accordance with an embodiment of the present invention. As shown in figure 3, the top dome (103) of the tank (150) is a hollow frustum complementing the tapered bottom (105), i.e., the top dome (103) of the tank (150) is in accordance with the tapered bottom (105). For example, where, the tapered bottom (105) is the tapered cylindrical shape, in that case, the top dome (103) may be a hollow frustum cone covering the circumference of the tapered cylindrical shape. The top dome (103) may comprise, as shown in figure 1 , a flange (11 1) to lock or join with the tapered bottom (105). The flange (11 1 ) may rest on the circumference of the tapered bottom (105). Further, in an additional or alternative embodiment, the top dome (103) may comprise a structure to form a man-hole to facilitate servicing of the tank (150).

[035] Further, as shown in figure 1 and 2, between the first part (102) and the second part (104) of the mould, a separator (106) is disposed which is adapted to separate the top dome (103) and the tapered bottom (105). The separator (106) may be made of same material as of the mould. The separator (106) may be shaped similar to the shape of top of the tapered bottom (105). For example, the shape of the separator (106) may be a circular ring in case the predetermined tapered bottom (105) is the tapered cylindrical shape. Further, the shape of the separator (106) may be a square or rectangular in case the predetermined tapered bottom (105) is the tapered cuboidal shape.

[036] In accordance with an embodiment of the present invention, as shown in figure 2, the separator (106), the first part (102) and the second part (104) may be held together with one or more pins (110), where each pin of the one or more pins

(110) is placed in the separator (106), passing through the first part (102) and the second part (104) of the mould. The pin is adapted to leave a hole on a flange

(11 1 ) while forming the top dome (103). The one or more pins (110) may be made of same material as the mould.

[037] Further, in an additional or alternative embodiment, the system (100) may comprise one or more niches near bottom (109) of the second part (104) for making holes in the tank (150) during installation of the tank (150) for connecting liquid out flow pipes. The one or more niches may have indentations or markings.

[038] The invention works in following manner:

[039] As shown in figure 1 and figure 2, the first part (102), the second part (104), the separator (106) and the pin together are adapted to form one or more cavities (108) in between. In accordance with an embodiment of the present invention, as shown in figure 2, the one or more cavities (108) may form the flange (11 1 ) on the top dome (103) of the tank (150). Each pin of the one or more pins (110) is adapted to leave a hole on the flange (11 1 ) while forming the top dome (103).

[040] Next, the mould is configured to rotate in order to fill the one or more cavities (108) with a filler. In accordance with an embodiment of the present invention, the filler may be selected from, but not limited to, Nylon, High-Density Polyethylene (HDPE), Low density Polyethylene (LDPE), Polycarbonate (PC), Polyoxymethylene (POM), Acrylic Poly (Methyl Methacrylate) (PMMA), Thermoplastic Polyurethane (TPU), Thermoplastic Rubber (TPR), Polypropylene (PP), Acrylonitrile Butadiene Styrene (ABS), or a combination thereof.

[041] The mould may be rotated in any or all directions to evenly distribute the filler evenly inside the one or more cavities (108) of the mould. The mould may be rotated with the help of, may be, but not limited to motors, gears disposed at multiple axis (X, Y, and Z) of the mould. The filler, after even distribution inside the one or more cavities (108), form the top dome (103) and the tapered bottom (105) thereby forming the tank (150), as shown in figure 3, inside the mould with the filler in the one or more cavities (108). Walls of the tank form an angle (A) in range of 90.5° to 135° with bottom of the tank.

[042] As shown in figure 3, the tank (150) is formed. However, it may be appreciated by a skilled addressee that the tank (150) may be formed using any other technique of moulding such as, but not limited to, extrusion moulding, compression moulding, blow moulding, and injection. The tank may be made of, but not limited to, but not limited to, Nylon, High-Density Polyethylene (HDPE), Low density Polyethylene (LDPE), Polycarbonate (PC), Polyoxymethylene (POM), Acrylic Poly (Methyl Methacrylate) (PMMA), Thermoplastic Polyurethane (TPU), Thermoplastic Rubber (TPR), Polypropylene (PP), Acrylonitrile Butadiene Styrene (ABS), or a combination thereof.

[043] In accordance with an embodiment of the present invention, as shown in figure 3, the tank (150) may comprise a predetermined tapered bottom (105) having a first end (156) and a second end (157). As shown in figure 3, the second end (157) having a lesser area than the first end (156). In accordance with an embodiment of the present invention, the tapered bottom (105) may a predetermined taper angle (A), as shown in figure 3. The walls of the tank (150) form the angle (A) in range of 90.5° to 135° with bottom of the tank (150). Figure 3A illustrates a tank having tapered polygonal shape such as a tapered cuboidal shape, in accordance with an embodiment of the present invention.

[044] As shown in figure 3A, all the vertical side of the tapered cuboid are making an angle A with the base of the tapered cuboid. The vertical sides and the base together forming a tapered bottom (105). Furthermore, as shown in figure 3A, the top dome (103) is complementing the tapered bottom (105).

[045] As shown in figure 3 and 3A, the predetermined taper angle (A) may cause the second end (157) having a lesser area and periphery than the first end (156). Further, as shown in figure 3, the tank may comprise the top dome (103). The top dome (103) of the tank (150) may be a hollow frustum complementing the tapered bottom (105). The top dome (103) may have a flange (11 1 ) adapted to rest over the first end of the tapered bottom (105). Further, as shown in figure 3A, the top dome (103) may comprise a man-hole (158) to facilitate servicing of the tank (150). Further, the flange (11 1 ) may have one or more holes configured to join the top dome (103) with the tapered bottom (105).

[046] In an additional or alternative embodiment, the one or more niche may have the filler moulded into the indentations or markings. The indentations or markings may be cut out for making holes during installation of the tank (150) for connecting liquid out flow pipes.

[047] Further, after the separator (106) is removed, the top dome (103) and the tapered bottom (105) of the tank (150) are separated. After the separation, the tapered bottom (105) may be stacked as shown in figure 4. As shown in figure 4, the tapered bottom 105i, 1052, 105s, 1054, 105 ₅ ... 105 _n are arranged in a stack taking up much less volume than just the space occupied by a single tank (150). The top domes (103) are also stacked the same way as the tapered bottom (105).

[048] Further, figure 5 illustrates variables for efficient stacking of the tanks (150 _n ), in accordance with an embodiment of the present invention. The packing efficiency has been defined as the factor by which the storage of tanks (150 _n ) will increase by stacking one over other is calculated as (H/h+1 )/2. Where, H being tank (150) height, the gap between two tanks bottom (155) being h; t being thickness of the tank (150); and A the angle the walls form with the bottom (155), the gap h= (t/tan (A-90)) +t.

[049] After the top dome (103) and the tapered bottom (105) are stacked efficiently and transported, the top dome (103) and the tapered bottom (105) are put together to form the tank (150). The flanges (11 1 ) on the top dome (103) grips the circumference of the tapered bottom (105). The flange (11 1 ) may be fixed on the circumference of the tapered bottom (105) using may be, but not limited to, rivets, screws through the holes, glue, solvents etc. In an embodiment, a sealant may be used between the top dome (103) and the tapered bottom (105) to prevent any leakage of fluids.

[061] The present invention has various advantages. The invention provides cost effective approach and economic significance over the existing prior arts. The invention helps in ease of transport thereby facilitating mass production and easier distribution. Due to transportation in bulks, overall cost of the tank is significantly reduced since multiple tanks can be carried at once at a single instance. For making the water tank design transportation efficient, the design should allow the stacking of the water tanks. Each of these parts can be stored in a stack which, based on the design parameters, the invention will save 70 to 90 % space during transportation in bulk. The main water tank may be created using the shape of hollow reverse conical frustum with bottom installed and top absent. The top has a built-in flange in which the doe part will rest. The taper angle is suitable chosen as per individual design. [062] A taper angle of 135° may allow an efficiency of 90% where, for example, 11 units of 100 cm height are stacked together. Higher height of stacking will improve the efficiency further without causing any harm to products. Suitable profile is added to the design so as to provide the required strength to the walls. The invention can be retrofit. The manufacturers can adapt new design in the existing facilities by making changes to existing dies. Therefore, there are minimum to no cost of change in technology. No investment in costly in injection moulding dies for saving on freight. Further, there is no need to use any sealant or gaskets.
