Abstract
Base and cover elements () of a food container () can be rapidly closed at a plant and can be easily opened and closed by a customer. The cover has a lower rim wall () with a plurality of radially inward cover projections () spaced about the container axis (), and the base has a base rim wall () with a plurality of recesses () with undercut grooves () that each receives a cover projection to hold the cover closed on the base. The bottom surface () of the cover projections and the top surface () of the base rim wall are beveled, so the cover can be installed by forcefully pushing it down, at any rotational position of the cover on the base. The cover then can be easily removed by turning it, with the cover projections moving along undercut base grooves (), until the cover projections reach vertical passages () through which the projections can be easily lifted. The base has a handle () to prevent the base from turning, comprising a sheet-like tab that projects radially outward under the cover and that forms upstanding shoulders ().
