Abstract

PURPOSE: To eliminate the scattering of pieces of broken glass and to eliminate the need for a drying process by putting a bag body in a glass container and then by applying fixed pressure onto the inside wall surface of the glass container by inflating the bag.
CONSTITUTION: Once hydraulic cylinder 7 starts discharging water, the water flows into bag body 4 via a pipe and bag body 4 is inflated inside of glass container 1. After bag body 4 is in close contact with the inside wall surface of glass container 1, hydraulic cylinder 7, still discharges water but the inside water pressure of bag body 4 increases rapidly as a result, thereby applying high pressure to the inside wall surface of glass container 1.
