Prefabricated cylindrical container

Abstract

The present invention provides an assembly-type cylindrical container made of plastic material that exhibits minimal deterioration even after repeated assembly and disassembly over a long period of time, and has a small volume when disassembled, making it easy to handle and maintain. [Solution] The device comprises a body portion having locking parts at both ends of a rectangular resin plate, which is rolled into a cylindrical shape and detachably joined at both ends by the locking parts; an upper frame portion having a peripheral wall that extends downward from the periphery of the top plate and engages with the upper end of the body portion, and a central hole; a lid that engages with the central hole of the upper frame portion; and a bottom plate portion having a peripheral wall that extends upward from the periphery of the bottom plate and engages with the lower end of the body portion. The device also includes belt attachment fittings that are attached to the engagement surfaces of the peripheral walls of the upper frame portion and the bottom plate portion in a manner that does not interfere with the body portion, and that allow the upper frame portion and the bottom plate portion to clamp the body portion.

Claims

1. A body section having locking parts at both ends of a rectangular resin plate, which is rolled into a cylindrical shape and has the two ends detachably connected by the locking parts, An upper frame portion having a peripheral wall and a central hole that extends downward from the periphery of the top plate and engages with the upper end of the body portion, A lid that fits into the central hole of the upper frame, It comprises a bottom plate portion having a peripheral wall that extends upward from the periphery of the bottom plate and engages with the lower end of the body portion, Belt mounting brackets are attached to the mating surfaces of the peripheral walls of the upper frame and the bottom plate, respectively, with the body portion, in a manner that does not interfere with the body portion, and are used to attach a belt that allows the body portion to be clamped between the upper frame and the bottom plate. A modular cylindrical container having the following features.

2. The upper frame portion and the bottom plate portion of the body have multiple anti-rotation protrusions at various locations on the mating surface. The mating surfaces of the peripheral walls of the upper frame portion and the bottom plate portion with the body portion are provided with recesses that fix the anti-rotation projection at positions corresponding to the anti-rotation projection. The assembly-type cylindrical container according to feature 1.

3. The bottom surface of the base plate on which the body portion is placed is provided with drainage holes at multiple locations. The assembly-type cylindrical container according to feature 1.
