Abstract: Containers for storing food in a storage compartment may include a base portion of the container. The storage compartment is sealed with a film to get the food stored in the storage compartment fresh. The container further includes a reversible lid that is able to attach to the base portion of the container in two different configurations. In a first configuration the reversible lid attaches to the base portion without affecting the seal created by the film. In a second configuration the reversible lid attaches to the base portion when the lid is inverted and the film is removed from the base portion.

Abstract: A respirator mask facepiece thermoformed from a sheet of polymer material includes an opening that is covered by a filter membrane, which may be part of a detachable disposable filter cartridge. The polymer material of the facepiece may be transparent to enable a wearer's lips to be seen. The filter cartridge may include a filter membrane attached to a carrier frame, and may be attached to the facepiece via a set of threads formed on the carrier frame and the facepiece, which draw the cartridge and facepiece together to form a seal therebetween. A latch, catch, or other similar structure may be formed in the facepiece and/or carrier frame to inhibit the cartridge from being inadvertently detached from the facepiece.
