Abstract: The present invention relates to a heat-insulating cooking container comprising: a heat-insulating outer container and an inner container having an inner-container cover, the inner container being accommodated in the heat-insulating outer container, an aperture portion of the heat-insulating outer container being openably and closably covered by a heat-insulating-outer-container cover, wherein: a thermometer is installed on the heat-insulating-outer-container cover; a temperature-sensing member of the thermometer unit is located on an interior-surface side of the heat-insulating-outer-container cover; and the inner-container cover covers the temperature-sensing member upon opening the heat-insulating-outer-container cover and placing the inner-container cover on an interior surface of the heat-insulating-outer-container cover.

Abstract: A heat insulating container is provided with an outer vessel 2 and an inner vessel 1 arranged in the outer vessel 2 with a gap 3, at least a bag 4 arranged in the gap 3, and a reinforcement member 10 with a rigidity higher than the composition material of the bag 4, arranged on at least one peripheral side of the bag 4. The reinforcement member 10 extends along the edge portion of the bag 4. The bag 4 is formed into a rectangular shape, and the reinforcement member 10 is arranged along at least two opposite sides of the bag 4. As a protrusion of one of the inner or outer vessels engages with the cavity or the protrusion of the reinforcement member 10 of the bag 4, the bags 4 can be easily inserted into the gap 3.

Abstract: A plug for a liquid container comprises an outer plug, an inner plug and a fixing device. The outer plug is substantially a cylinder shape with a bottom wall and detachably installed onto a liquid container, wherein a liquid passage hole is penetrated through the bottom wall, and a liquid passage is formed between the bottom wall and an upper opening of the outer plug body. The inner plug is pivotally connected to the outer plug through a hinge, wherein the inner plug further comprises a liquid inlet seal member for sealing the liquid passage hole and a liquid outlet seal member for sealing an inner wall near the upper opening of the outer plug. The fixing device is used for fixing the inner plug onto the outer plug.

Abstract: There is provided a cap body of a beverage container where a large amount of beverage in a container body doesn't flow out, and a lid member is not vigorously released even if hot beverage is put in the container, and where a degree of freedom to select a spring is improved by alleviating impact force in an opening operation, the cap body of the beverage container comprising: a cylindrically-shaped drinking mouth member releasably provided in a mouth portion of a container body; a lid member connected to the drinking mouth member via a hinge axis; a spring for urging the lid member to the opening direction; and a lock member provided in a position against the hinge axis of the drinking mouth member for maintaining the lid member in a closing state, wherein the drinking mouth member comprises a drinking mouth formed in the lock member side of a peripheral wall of the upper opening; a bottom wall where hinge axis side is made higher than the drinking mouth side; a liquid hole formed in the drinking mouth side a

Abstract: Disclosed is a cap for a drink container which permits drinking of the drink contained therein without removing the cap. The cap comprises a cover plate which is to cover the upper opening of the drink container and a peripheral wall of the cover plate which is to be fitted to the upper opening edge of the drink container. The cover plate is disposed diagonally in the peripheral wall and has a liquid port at a low position. A plugging member for closing the liquid port is pivotally supported on the upper surface of the cover plate substantially at the center thereof. The peripheral wall has a notch in which the plugging member is to be retracted when the liquid port is closed thereby. The plugging member is locked onto the cover plate when the liquid port is closed by the plugging member, whereas the plugging member is locked onto the peripheral wall when the liquid port is let open.
