摘要
The invention concerns a multi-purpose and multi-use cleaning or treating device, in particular for personal hygiene, comprising at least a cleaning or treating head (20, 13). Said head comprises an element (20) made of sponge plastic material capable of adopting any desired shape by the effect of forces applied thereon and to resume at least partially its original shape, preferably plane, when these forces are absent, and a support (13) whose shape said element (20) can match when it is folded down and arranged thereon for covering it at least partially. Retaining means (30) co-operate with the element (20) and the handle (10) to ensure proper hold of said element on said support. The support (13) comprises gripping means directly mounted, such as grooves, or intrinsic, by the very material of which the support is made, for example a resin or an elastomer. The supports can be of different shapes. This device can be made in the most varied dimensions, thereby making it useful for many different purposes (personal hygiene, medical or veterinary use, craftwork, in one dimension scale; industrial and domestic use in another dimension scale).
