• Such drums or other similar containers are commonly made of plastic, steel or fiber.
• a tight head drum is a drum in which the top is not removable and it has bung hole in the top that allows the insertion of a faucet or a pump.
• Said tight head drum is usually used to store liquid material.
• Liquid material can be drawn off by pump suction from the top of the drum.
• An open top drum is a drum in which the entire top of the drum is removable and is usually used for storing solid or semi solid materials. The materials stored in said open top drum are removed by first removing the top of the drum and then pumping or pouring the materials out.
• Open top drums are frequently used for shipping products due to their ease of handling and versatility. Open top drums are desirable because the user can access the drum contents easily, for example, loading and unloading of the materials easily and quickly.
• the conventional open top drum is more costly than a closed top drum and the open top drum is non folding and therefore cannot be easily nor economically reused due to the high cost of repositioning.

• bottom end cap (150) is positioned at the lower end of said inner sleeve (120) and said outer sleeve (130) whereby the side wall (320) of said bottom end cap (150) is being inserted into the lower portion of the gap between said inner sleeve (120) and said outer sleeve (130) and the arrangement is such that the side wall (320) of said bottom end cap (150) is being sandwiched and fits snugly between said inner sleeve (120) and said outer sleeve (130).
• Said top end frame (140) and said bottom end cap (150) are held in place to said inner sleeve (120) and said outer sleeve (130) by using of locking means (160).
• Said locking means (160) comprises of at least two reinforcing straps (160), whereby the arrangement is such that said straps (160) travels between the outer wall of said inner sleeve (120) and the inner wall of said outer sleeve (130).
• One end of said strap (160) passes through a passageway formed between the outer wall of the inner sleeve (120) and the inner wall of the outer sleeve (130), from one of the guiding loop (230) at said top end frame (140) towards one of the corresponding slot (330) at said bottom end cap (150), whereby said corresponding slot (330) is positioned vertically in alignment with said guiding loop (230).
• Each of the end of said strap (160) is positioned at the passageway formed between said inner sleeve (120) and said outer sleeve (130) correspondingly so that both end of said strap (160) are tensioned and heat sealed (190) therein respectively, or fastened by any other known fastening means so as to hold both of said top end frame (140) and bottom end cap (150) in place to the inner sleeve (120) and the outer sleeve (130).
• four straps are used in said octagonal-shaped container whereby two of the straps are parallel to each other and the other two are substantially perpendicular to the first two straps.
• said open top container of the present invention further comprises of at least one reinforcing middle sleeve (170) that is positioned between said inner sleeve (120) and said outer sleeve (130) as shown in FIG. 1-B to strengthen said container when it is in erected position.
• Said reinforcing middle sleeve (170) is being sandwiched by said inner sleeve (120) and said outer sleeve (130), whereby the side wall (220) of said top end frame (140) is on top of said middle sleeve (170) and the side wall (320) of said bottom end cap (150) is below said middle sleeve (170).
• said open top container may receive a liner (not shown) contained within the inner part of the body of said container.
• Said liner can be a flexible bag made of a suitable plastic, such as but not limited to polyethylene, polypropylene, or any other polymer materials that may be utilized for receiving of the filled material.
• Said liner may be disposable and a new liner is used for subsequent filling and discharging of materials.
• Said open top container further comprises of a pallet portion (180) which is moulded into the base portion of said container integrally to said bottom end cap (150).
• Said pallet portion (180) would enable the tines of a forklift to engage said pallet portion (180) to lift and carry the container.
• the user can lift the container easily from the ground and transfer said container to a desired location.
• said top closure (110), said top end frame (140) and said bottom end cap (150) are removed from said container by cutting said straps (160) which secure said top end frame (140) and said bottom end cap (150) to said inner sleeve (120) and said outer sleeve (130).
• Said inner sleeve (120) and said outer sleeve (130) are then adapted to be folded into a flat sheet respectively.
• Said inner sleeve (120) and said outer sleeve (130) can be folded to substantially 2.5 : 1 ratio when said open top container is empty.
• Said inner sleeve (120) may is separated from said outer sleeve (130).
• multiple sleeves can be stacked on each other to save the storage space. Thus, by having such an arrangement, the shipping cost for the empty container can be reduced.
