Embodiments of the present invention relate to domed metal containers, and more specifically to pressurized metallic food containers with liquid nitrogen wells and various closure mechanisms. In some embodiments, the metallic food containers are thin-walled aluminum and are pressurized using liquid nitrogen to maintain strength and integrity. The container can have a nitrogen well to receive liquid nitrogen and keep the liquid nitrogen away from the food stuff packaged in the container. In various embodiments, the metallic food container comprises a domed bottom portion shaped and sized to nest with a food stuff packaged in the container. In some embodiments, the container is sealed with a tear away lid, a screw-on lid, or a metallic end closure double seamed to the container.

To solve the above problem, a pouch forming apparatus according to an embodiment of the present invention includes: a die in which a forming space is recessed inward from a top surface thereof; a partition wall partitioning the forming space into first and second forming spaces; a stripper disposed above the die and configured to descend to contact the die with the pouch film therebetween to fix the pouch film to be seated on a top surface of the die; and an electromagnetic force generation part disposed above the forming space and configured to generate electromagnetic force and configured to apply the electromagnetic force to the forming space.

Provided are a washing machine that can be manufactured in a large capacity without deterioration in function, and a manufacturing method thereof. A washing machine includes a drum, a drum back, and a spider. The drum back includes a coupling portion formed to protrude in a front direction of the drum at a portion of the drum back to which the spider is coupled so as to correspond to a shape of the spider, a first forming portion formed to be recessed in a back direction of the drum at a portion of the drum back to which the spider is not coupled, and a reinforcement portion formed to additionally protrude in the front direction of the drum at a portion of the coupling portion that is adjacent to the first forming portions.

In accordance with one embodiment of the invention, there is provided an improved disposable aluminum pan for use with a chaffing rack and a pair of half pans. The pan includes a base terminating to a sidewall and an rim, which terminates to a rolled bead. The pan includes an inside length measured longitudinally across opposing sidewalls from the inside edge of the rim. The inside length is configured to be shorter than a corresponding inside length of an unimproved pan. The pair of half pans when nested side by side in the improved pan can have adjacent sides of the half pans lay without overlap. The pan also allows for a lid to fit better. The pan also includes a deeper well such that the bottom is positioned closer to burners in the chaffing rack and allows more water to be added during the heating process.
