A vessel (e.g. a trigger spray bottle) has one or more openings for the application of fluids. The vessel further comprises a recyclable porous scaffold (1) impregnated with chemicals that can be released, dissolved, rehydrated or re-suspended from a dried form or from a concentrated liquid form by the addition of water, for example by the end user. The vessel also comprises a means for adding water to the vessel, a means for closing one or more openings in the vessel a means for adding further impregnated scaffolds and a means of expelling the released, dissolved, rehydrated or re-suspended from the vessel. A weight (5) may be attached to the scaffold by a string (4) to aid removal of scaffold from the vessel. |
