According to one example, a removable lid for a container of a vessel includes a valve configured to selectively allow air to vent out of a fluid retaining interior region of the container when the lid is positioned on the container. The valve includes an opening that extends entirely through a thickness of a portion of the lid, and a valve plug. The valve plug includes a valve top portion that extends vertically above a top surface of the portion of the lid, a valve bottom portion, and a valve central portion. The valve top portion is configured to be contracted, by a downward pressure, into a more vertically compact shape. The valve top portion is further configured to, absent the downward pressure, expand back upwards out of the more vertically compact shape.

The present invention relates to a portable thermal container (1) for consumer products (2′) comprising at least a storing chamber (2) of the consumer products (2′) and at least a reaction chamber (4) of a reagent component (5′) and a of a reactive component (5″), wherein the reaction chamber (4) extends substantially entirely along the dimension of the largest dimension of the portable thermal container (1) and the storing chamber (2) is arranged side-by-side to the reaction chamber (4) to maximize the thermal exchange between the reaction chamber (4) and the storing chamber (2) in an homogeneous way, and the reaction chamber (4) comprises at least a storing portion and at least an expansion portion, wherein the total volume of said expansion portions is greater than the total volume of said storing portions to allow the safe expansion of the chemical reaction gases in said reaction chamber (4).

The invention relates to a vacuum skin food package for use in a conventional oven and more particularly to a food package able to withstand conditions up to 200° C. comprising a thermoplastic lid film which is free of polyester and contains crosslinked EVA.

A microwave heating sheet includes a substrate and a heating layer disposed on a first surface of the substrate. The heating layer includes a polar solvent that has a boiling point of not less than 100° C. and a polyelectrolyte that is dissolved in the polar solvent.

A process and apparatus for heating a microwave transparent material or di-polar material. The apparatus includes a vessel that has susceptor material on at least a portion of the vessel walls. Microwaves are generated by a microwave transmitter and introduced into the vessel which can heat both microwave transparent materials and di-polar materials within the vessel.

A recyclable woven laminated plastic bag having features that further prevent leakage of contents out of the bag, or infestation of organisms into the contents of the bag is provided. In various aspects the bag can be fabricated from a woven polyethylene, polypropylene, or combination thereof layer which can be laminated using polyethylene, polypropylene, or combination thereof resin with a film layer formed from polyethylene, polypropylene, or combination thereof, can form a sealed corner bag and/or a diagonal sealed bag, and can have one or more sides include graphics and/or printing. The bag can also provide a top end and/or a bottom end either or both of which provide a discrete area which may contain discrete graphics and/or printing.

The present invention relates to cross-linked vacuum skin packaging (VSP) films used as top webs for VSP packages endowed with easy opening features and to VSP packages obtained therefrom. The films of the invention comprise at least one layer of a frangible blend of incompatible polymers. The easy-to-open VSP packages obtained therefrom may advantageously include very simple and cheap supports.

RFID tags are provided for incorporation into the packaging of a microwavable food item. The packaging includes a first member (e.g., a tray) that is configured to be microwaved and a second member (e.g., a sleeve or box or enclosure) that is configured to be dissociated from the first member prior to microwaving the first member. The RFID tag includes a reactive strap associated with the first member and a far-field antenna associated with the second member. The reactive strap is coupled to the antenna when the packaging is intact, while being decoupled from the antenna when the second member has been dissociated from the first member. The RFID tag is capable of far-field communication when the reactive strap is coupled to the antenna, while the reactive strap is capable of only near-field communication when decoupled from the antenna.

To suppress damage such as the formation of holes and wrinkles in laminated bodies constituting a bag. A bag having a storage section includes: laminated bodies that include a sealant film positioned on an inner surface of the bag and at least one plastic film positioned on an outer surface side of the sealant film; and a seal section where inner surfaces of one pair of laminated bodies are joined together. The seal section has an outer edge seal part that is positioned along an outer edge of the bag, and a steam-releasing seal part that is positioned closer to a center point side of the storage section than the outer edge seal part and peels off due to an increase in pressure in the storage section. The steam-releasing seal part peels off when the pressure in the storage section is 130 kPa or lower.
