Garbage bag container device for e.g. public building, has cylindrical body whose internal expansion is caused by vertical division of its interior doubled part by number equal to bands that are shifted laterally from semi division

摘要

The device has a cylindrical body (1) whose internal expansion (2) is caused by vertical division of its interior doubled part by a number equal to bands (4). The bands are shifted laterally from a semi division (3) and connected to the ends of the division such that the bands permit free deformation of material under the explosive effect. Top of the body is covered by a flange (11).
