The sponge counting bag is formed of front and back sheets of transparent polymer material which are joined at the edges and bottom to form an open-topped bag. The back sheet extends above the front sheet. The front sheet is folded down to form a cuff, and the lower edge of the cuff is stretched to form wrinkles whereby the lower edge hangs outwardly away from the bag so that the cuff can be manipulated easily to pull the bag open. In one species, the top of the back sheet forms a flap which can be folded down to cover the otherwise open top. This flap is detachably, adhesively attached so that the bag normally remains closed, but can be reopened if necessary. Another species has a plurality of cuffed bags arranged one above the other so that the plurality can be hung from one support.

A sponge counting bag comprising: a front layer and a back layer of flexible synthetic polymer composition sheet material, at least said front layer being substantially transparent, said front layer and said back layer being attached to each other to form a left edge, bottom edge and right edge of said bag, leaving its top open, said back layer extending above the open top of said bag, said front layer being folded downward from said open top of said bag to define a cuff having a downwardly directed edge, said cuff being wrinkled so that said cuff does not lie completely flat against said front layer so that said cuff can be readily engaged to pull said front layer away from said back layer to open said bag, said back layer being sufficiently long so that it can be folded down below said cuff to close said bag; and a tack seal between said front layer and said back layer positioned so that said tack seal limits the opening of said bag, said tack seal being sufficiently soft so that said tack seal can be broken away for full access to the interior of said bag without perforating said bag.
