The present invention provides a container (10a) including sidewalls (12a) generally upstanding from the base floor. A rim (14a) at least partially defines an opening through which product is to be inserted in the container (10a). At least a portion of the base floor is made up of at least one contoured base floor section (28a) which adjoins a sidewall (12a) at an upwardly arched portion (18a) and a perimetric portion of the contoured base floor section. A portion of a rim is contoured (36) to arrive in close proximity to an adapted rim extension (38) when the lid (16a) is in a closed position.
