ABSTRACT:
A pouring receptacle has a closure that can be pressed open and which is resiliently returned to closed position when pressure is released. The receptacle proper has diametrically opposed upwardly open slots with enlargements at their lower ends, the enlargements receiving bosses on the cover and the slots receiving elongated lugs on the cover in the closed position of the cover. The material of the cover or receptacle proper is resilient, so that when the cover is pressed, it will swing about the bosses and the lugs and/or side walls of the slots will resiliently deform sufficiently to permit opening, this resilient deformation serving to urge the cover to the closed position upon release of pressure.
