The cup can include a groove below the outwardly rolled lip in the inner face of the cup wall. The cup can be provided with stacking ribs within the cup to aid in stacking of two or more cups. The cup can include a tapered lid with an outwardly flared lip that seats against the inner wall of the cup and that does not extend over the lip of the cup. The lid can include a locking ring below the outwardly flared lip of the lid that is adapted for insertion into the groove in the cup. The lid further includes a fluid port.
