A vented sealable bag comprises a container, a two-part seal and a vent. The container has opposing sidewalls and a bottom defining a cavity. The sidewalls form a neck defining an opening opposite the bottom, The sidewalls have an inner surface facing the cavity and an outer surface external to the container and the sidewalls have a thickness. A two-part seal is formed on the inner surface of the sidewalls adjacent the neck. The two-part seal has a hook formed on one sidewall and a clasp formed on an opposite sidewall. The hook and clasp are arranged on the inner surface of the sidewalls to form an airtight seal isolating the cavity from an external environment when the hook is embedded in the clasp but otherwise maintain the opening in the container. A vent is integrally formed in one of the sidewalls. The vent is further comprised of a dimple having a thickness that is thinner than the thickness of the sidewalls. The dimple is concave when viewed from the cavity and has a slit formed at an apex that is closed except when the container is sealed and an internal pressure is created that is higher than an external pressure on the outer surface of the sidewalls.

An egg apparatus has a top shell and a bottom shell designed to attach and detach to one another and when attached, the shells form a sealed internal cavity, the top shell having at least one aperture and the bottom shell having a tray for receiving an egg, the bottom shell is designed to receive water which can be heated to cook the egg; and a pop valve designed to fit within the aperture of the first shell and allows steam to escape while keeping the water inside the internal cavity formed by the two shells.

The present invention is directed to retortable, hot-fill and/or microwavable liquid dispensing packages. The packages include is a line of weakness having a sinusoidal shape in each front and rear panel of the package which are substantially coincident with one another. To drain liquid from the package, a first removable portion can be torn away from the package by manual force separating at the lines of weakness to create a plurality of liquid-passage openings in the remaining portion of the package which extend laterally across the width of the package.

A method for using a paperboard article includes heating a paperboard article by way of microwave radiation. The paperboard article includes a paperboard substrate having a first major side and a second major side and one or more high-density polyethylene layers on at least one of the first major side and the second major side of the paperboard substrate.

The invention relates to a bag, based on the conventional structure of a bag of this type, characterised in that the free end vertices (7) thereof have a bevelled or rounded configuration, which, during the unfolding caused by the increase in volume due to the cooking of the corn grains inside said bag, prevents the bag from being able to remain blocked or held back against the lateral walls of the microwave, preventing the rotation thereof, which ensures a homogeneous distribution of heat over the corn grains, thereby preventing a large number of grains from not cooking properly, as occurs with the conventional popcorn bags.

A microwave compatible container for heating food can comprise a bottom wall, outer and inner walls extending from the bottom wall, and a removable top. The outer wall can have an exterior surface and an interior surface. The inner wall can have an exterior facing surface and an interior facing surface. The interior facing surface of the inner wall and the bottom wall can define an inner compartment of the container. Further, the exterior facing surface of the inner wall, the interior surface of the outer wall, and the bottom wall can define an outer compartment that surrounds the inner compartment. The removable top can be sealingly engaged with the outer wall and/or the inner wall in a closed configuration such that the inner compartment is sealed from the outer compartment. Food can be placed within the inner compartment and water can placed in the outer compartment during microwaving.

Embodiments herein relate to an ultrasonically weldable polymeric lid for a microwaveable polymeric container. In an embodiment, a lid for microwaveable containers can include a polymeric ring. The polymeric ring can define a central aperture having an inner diameter. The polymeric ring can also include a recessed shelf contacting the inner diameter of the central aperture and an ultrasonic bonding surface disposed to the outside of the recessed shelf. The lid can include a peelable film disposed on the recessed shelf and occluding the central aperture. The peelable film can be removably bonded to the recessed shelf, and can include a tab attached to an edge of the peelable film. In some cases the lid can contain substantially no metal content. Other embodiments are also included herein.

A food container for a microwave oven consisting of a polypropylene inner container and a paper outer shell, wherein the polypropylene inner container is inserted into and adhered to the paper outer shell. The polypropylene inner shell container 31 is molded to a minimum thickness of about 0.1 to 0.3 mm to maintain heat resistance and formability. In order to be molded into such a thin container, polypropylene resin must be manufactured through vacuum molding or air press molding. The weight ratio of the polypropylene inner container and the paper outer shell is preferably in the range of 1:1 to 2. In the case of a 1-liter container, the weight of the container is preferably about 20 to 24 g, and the polypropylene inner container is preferably about 8 to 12 g, the paper outer shell preferably about 12 to 16 g.

A kit and method for preparing asphalt for small-scale paving applications. The kit includes a brick of asphalt, an oven bag, and a microwavable container. The method includes placing the brick of asphalt into the oven bag, sealing the oven bag in an airtight manner to prevent the escape of toxic fumes, placing the oven bag into the container, sealing the container, placing the container into a microwave oven, and heating the brick of asphalt in the microwave oven to a temperature sufficient for paving applications.

The present invention provides methods and systems for a vented storage container that includes a container that has an upper mouth-defining structure, a base, and a plurality of walls extending from the base, forming a cavity therein. The lid is fixable to the upper mouth-defining structure, wherein the lid has a top surface and a bottom surface, and at least one hole formed within the lid. A valve is engaged to the lid and covering the at least one hole.
