Patent attributes
A pail having a cylindrical sidewall with an upper margin defining an opening generally equal to the sidewall diameter, a thread projecting outwardly from the sidewall below the upper margin, and at least one flange projecting outwardly from the sidewall below the thread, each flange including one or more radial projections and portions on either side of the radial projections extending outward from the sidewall at least as far as the radial projections. A cover having a central portion received within the opening, a mating portion extending outward from the central potion to engage the sidewall upper margin, a downwardly projecting rim including at least one inwardly directed thread to engage the thread projecting outwardly from the pail sidewall, and at least one tab integrally coupled to the downwardly projecting rim including one or more apertures corresponding to the plurality of radial projections, each tab being biased for displacement from an outwardly displaced disengaged position toward a more inward position with the radial projections being received in the apertures to lock the cover onto the top of the pail to enclose any contents of the pail, each tab including a lower edge extending sufficiently below the apertures to provide a grip allowing a manual outward force to be applied to disengage the tab apertures from the flange radial projections.
