摘要

A cover for covering an opening of a container for a food stuff includes a substantially flat cover body including at least one aperture and at least one substantially flat flap. The at least one flap including a linear proximal end configured to connect with the cover body and allow the at least one flap to rotate with respect to the cover body. A lower surface of the at least one flap includes a protrusion configured to close the at least one aperture when the at least one flap is at a first position in which the at least one flap is in parallel with the cover body. The cover body and the at least one flap are integrally formed by a co-injection molding. The container and cover are suitable for heating a food stuff in a microwave.

主权项

1. A cover for covering an opening of a container for heating a food stuff, the cover comprising:
an elevated peripheral portion defining an outer contour of the cover and configured to engage with an edge of the container defining its opening; an elevated area surrounded by and positioned apart from the elevated peripheral portion, the elevated area being lower than the peripheral portion; a plurality of air vent ports defined in the elevated area; at least one flap including a proximal end integrally connected to an edge of the elevated area, the at least one flap configured to rotate around the proximal end; at least one protrusion extending from a first surface of the at least one flap and configured to plug at least one of the plurality of air vent ports when the flap reaches a first position where the at least one flap is received in a concave area defined in the elevated area; and a groove defined at the proximal end in the first surface of the at least one flap wherein a second surface opposite to the first surface at the proximal end is straight when the flap stands upright to the concave area.
