Abstract
A plate container with detachable cover is disclosed. The container includes a base in the form of a plate and a cover. The plate and the cover include first and second closure portions, respectively, which are engageable with each other to maintain the cover in a secure position relative to the base and also forms a substantially leak-proof seal. The cover can include gripping tabs for facilitating the separation of the cover from the base and permit container venting. The plastic container is suited for microwave cooking, machine dishwashing, and freezer use.
Claims18
A container comprising:
- a base, the base having a plate-like configuration, the base having an exterior surface and an interior surface, the base including a first closure portion and a first stacking element;
- and
- a cover, the cover having an interior surface and an exterior surface, the cover including a dome portion, a second closure portion and a second stacking element, the interior surface of the dome portion being substantially concave, the second closure portion being adapted for sealing engagement with the first closure portion of the base so that when the first and second closure portions are engaged with each other, the cover and the base define a substantially sealed storage area;
- wherein the base is disposable in the interior of the dome portion of the cover such that a portion of the exterior surface of the base is in contact with a portion of the interior surface of the cover and the first stacking element is engaged with the second stacking element.
A container comprising:
- a base, the base having a plate-like configuration, the base including a first closure portion and a flange, the flange extending from the first closure portion and defining a perimeter of the base, the flange being resiliently flexible;
- and
- a cover, the cover including a second closure portion adapted for sealing engagement with the first closure portion of the base so that when the first and second closure portions are occluded, the cover and the base define a substantially sealed storage area;
- wherein when the first and second closure portions are sealingly engaged, the flange of the base is closely adjacent the cover, the flange of the base capable of being flexed away from the cover to facilitate the removal of the cover from the base.
A container comprising:
- a serving dish, the serving dish including a first closure portion having a first visual indicator element;
- and
- a cover, the cover including a second closure portion having a second visual indicator element, the second closure portion being engageable with the first closure portion to provide a seal between the cover and the serving dish, the cover and the serving dish defining a storage area when the first and second closure portions are engaged with each other;
- wherein when the first and second closure portions are engaged with each other, the first and second visual indicator elements cooperate with each other to provide a visual indication of closure of the cover upon the serving dish.
A method for making a container comprising:
- providing a base mold, the base mold having a base mold tool surface configured to define a base including a first closure portion, the first closure portion having a mating surface opposing the exterior surface of the base, and configured such that an exterior surface of the base is in contact with the base mold tool surface;
- molding the base via thermoforming;
- providing a cover mold, the cover mold having a cover mold tool surface configured to define a cover including a second closure portion, the second closure portion having a mating surface opposing the exterior surface of the cover, and configured such that an exterior surface of the cover is in contact with the cover mold tool surface;
- and
- molding the cover via thermoforming;
- wherein the mating surfaces of the first and second closure portions are configured to be engageable with each other to provide a seal between the cover and the base, and the respective mating surfaces do not contact the mold tool surfaces during the base molding and cover molding steps.
