  • Patent number: 8070016
    Abstract: A pouch is formed out of two sheets of plastic heat sealed over most of the edge length. The pouch has an expanding bottom feature and has a pouring spout formed by raised impressions in the corresponding sheets of plastic that form matching embossments. When the pouch is squeezed, the embossments open further apart to form a larger fluid passage at the outlet. The outlet of the pouch is opposite the bottom of the pouch and in at least one embodiment has a region on both sides of the outlet that are kept free from heat sealing during manufacture. The outlet also has a frangible line of weakness for easy opening. The outlet passage has two sets of embossments that meet along a center line to more fully expand the central portion of the pouch.

  • Publication number: 20100314385
    Abstract: An induction heating body 3 attached to an inner bottom surface 21 of a non-magnetic (or non-conductive) container body 2 in which heat is generated by eddy current induced by a high-frequency magnetic field has rising parts 32 provided along the outer periphery of a flat surface part 31. One or two or more of the rising parts 32 are partially cut, and the outer periphery of the flat surface part 31 at a part in which the rising part 32 is cut are allowed to serve as an open edge 32. With this configuration, a part which is selectively broken under specific conditions such as non-water heating is provided in the induction heating body 3 to enhance safety, and heating efficiency is prevented from being lowered in normal use. By effectively eliminating breakage by heat of the container main body 2, an induction heating cooking container is provided which enables cooking to be performed without problems and can be used easily.
