Abstract: A cooking tray for food, particularly including bacon, comprises a generally rectangular base with sidewalls that are somewhat inclined. A number of ribs or other suitable projections extend upward from the base to suspend the bacon above the grease that is produced during cooking. The lower surface of the base of the tray includes legs or other structures to facilitate a criss-crossed stacking arrangement during cooking. The sidewalls are preferably inclined somewhat to allow the trays to be nested for convenient storage of multiple trays.

Abstract: A unit dose injection cartridge (e.g., needleless injection cartridge) includes an elongated chamber, a sealable discharge outlet (e.g., nozzle orifice) and a piston seal slidable within the chamber from a proximal end region to a distal end of the chamber. The piston seal is movably securable at a first position within the proximal end region, wherein the chamber is fillable with medicament by way of a passageway extending past the piston seal from a proximal side to a distal side thereof. During filling, air is allowed to escape from the chamber through the same passageway used for filling, or a second similarly arranged adjacent passageway. Once a unit dose of medicament is metered into the chamber, the piston seal may be moved slightly distally to a second position within the proximal end region, whereby the chamber is sealed-off from the passageway by the piston seal.
