Zusammenfassung:	PURPOSE:To drop a packing material and crashing a flask body and to make the outflow of molten steel easy when a slide valve of a ladle opens, by packing the packing materials into the flask body of a bottomed cylindrical shape fitting into the bores of the openings of the insert nozzle and bottom plate of said valve. CONSTITUTION:The combustible materials in packing materials 4' in a packing body are burned away by the heat of the molten steel charged into a ladle prior to opening of a slide valve when said packing body is fitted into said opening, whereby the materials 4' are made sandy. The greater part of the packing material 4 is made into sand-like materials when the slide valve opens on account of the sandy packing materials, by which the materials 4, 4' are dropped, and a refractory flask body 1 on the molten steel side is crushed by pressing with the pressure of the molten steel in the ladle, and the molten steel is run out.
