Steaming-boiling container for microwave oven

Abstract

A container system for microwave oven cooking comprises a main body, a lid, and a cap disposed in a recess in the lid. The cap is movable upward and downward through a limited range in the recess depending on steam pressure, and grooves, formed in a side wall of the cap, or in a side wall of the recess, allow escape of steam when the cap is moved upward as a result of steam pressure. The lid is also allowed to move upward and downward relative to the main container body in response to steam pressure, and, when the lid is moved upward, an additional path for the escape of stem is provided at the location where the rims of the lid and main body meet each other.

Description

technical field [0001] The invention relates to a container for cooking in a microwave oven, in particular to a food container with a lid capable of automatically releasing thermal expansion steam. Background technique [0002] Microwave ovens are often used to heat food and beverages conveniently and easily. In the microwave heating of fresh food and processed food, a container made of a heat-resistant plastic plate with an airtight lid is widely used. Food and beverages can be contained in such containers and easily heated and steamed without removing them from the containers. [0003] Well-known microwavable containers have airtight lids and are capable of withstanding temperatures of about 120°C, which release the resulting expansion steam. The expanding steam can also escape through a groove in the fitting part of the container body when the lid is in place. Such a container is described in Japanese Patent No. 3009863. [0004] Problems are encountered with these c...
