This invention relates to new and useful improvements in cans and-has for its primary object the provision ofa device of the above stated character especially adapted for dispensing cleaning fluid andis arranged to deliver a small quantity of fluid directly to the Another object ofthis invention is the 'provisiongof means to be engaged Iand'pressed by thesponge or cleaning'element while held in one-hand to moisten the latter with the cleaning fluid, ,7 leaving the ;persons other hand free to handle the fabricgbeingcleaned and also obviate the :necessityofa person ren'ioving'the eyes from the part of the fabric being cleaned. A further ob amount of fluid to the sponge or cleaning element during each operation of the device;

'7 and will prote'ot'the majorportion .ofthe cleaning fluid fromfire when exposed to the flame of a match or the like;

" A still further object of this invention is the v provision of a can; of the above stated character whichwill be simple, durable and eflicient, and whichmaybemanufactured and sold at a comparatively low cost., s

With these and other objects .in view as will become more apparent as the description proceeds, the invention consists in certain; novel features of construction, combination and arrangement of partsfas will be 7 hereinafter more fully described and claimed. a

For a complete understanding of my invention, reference is to be had to the following,
