<p>A pouch 10 is folded from paper to have an elongated, openable mouth 16. The pouch is applied to a wall 19 below a point 20 where drilling is to be carried out by means of a strip 18 of a weak adhesive tape so as to protect a skirting board 21 at the foot of the wall from falling brickdust. After use the pouch is peeled off the wall and the extended top of the rear side 12 is folded over to close the mouth of the pouch and is held by a second strip 17 of adhesive tape on the front side 11 of the pouch. The pouch 10 with its contents safely contained can then be discarded.</p> |
