ABSTRACT:
An inexpensive, readily handled receptacle for use in the bulk impregnation of timber by vacuum impregnation is made of flexible fluid-impermeable material and, over parts of its walls, is of double thickness to form closed pockets that can be inflated to form a container of rectangular shape hinged along one of its side faces to provide a sealable opening for loading and unloading. The pockets have a valve for inflating them with air; the receptacle has inlet and outlet ports for evacuating the receptacle and introducing impregnant. Preferably, the receptacle is supported in a two-part rectangular frame hinged along one side face.
