There is disclosed an apparatus and methods for carbonating water or a water-based liquid from an effervescent composition. The apparatus may include a lid coupled to a container wherein the ratio of a volume capacity of a receptacle for effervescent composition to a volume capacity of the container for water or water-based liquid is greater than 1:986. A delivery device is disclosed to deliver an amount of effervescent composition from the receptacle to the water or water-based liquid when the lid and container are coupled to form a seal, wherein the seal holds pressure when the water or water-based liquid is carbonated. The apparatus further includes a pressure release mechanism coupled to one of the container or lid to release pressure when the container and lid are sealed and when the pressure increases above a seal strength and before the apparatus containing carbonated water or water-based liquid is open, and a headspace between an inside portion of the lid and a height of the water or water-based liquid with a volume capacity for gas to provide sufficient pressure when sealed to force carbon dioxide gas into the water or water-based liquid contents as carbonic acid.

A package includes: a packaging container having a containing section open at the top and formed by a bottom and by a peripheral wall rising from the peripheral edge of the bottom, the packaging container further having a flange formed thereon, the flange being provided along the entire circumference of the peripheral wall and protruding outward relative to the containing section from the upper end of the peripheral wall; a contained object contained within the containing section and producing vapor when heated; and a top seal joined to the flange along the entire circumference thereof to seal the inside of the containing section. The packaging container has a curved section where a part of the peripheral wall is curved toward the containing section. A maximum deformation point is formed in the curved section, the maximum deformation point being the point where the deformation of the peripheral wall is maximum when pressure within the containing section increases to deform the top seal. The deformed top seal and the flange are pulled in the direction in which the deformed top seal and the flange are separated from each other, and when pressure within the containing section exceeds a set value, the top seal is separated from the flange at the maximum deformation point to release vapor within the containing section.

The present invention relates to a pressure relief element (11) to be used as an overpressure safety means in devices where a gaseous medium must be rapidly released in case of overpressure, wherein the pressure relief element (11) has at least one notch (9) which is designed as a predetermined breaking point where the pressure relief element (11) breaks at a certain level of overpressure, thereby irreversibly opening an exhaust path for the gaseous medium. The present invention also relates to a pressure relief device of an electrochemical battery, comprising such a pressure relief element and a battery comprising such a pressure relief device.

A package has a seal portion that includes steam passage portions for externally releasing steam from inside the tray. The steam passage portion has an inner edge in which the portions configuring one side and the other side relative to the tip are curved and extended nearing each other toward the tip. The steam passage portion has an outer edge in a curved shape with a pointed tip, the shape being similar to that of the inner edge. The steam passage portion has a merging portion located between the tip of the outer edge and the tip of the inner edge, and a non-merging portion located between the merging portion and a common portion. The non-merging portion has a width narrowed from the common portion toward the merging portion.

The present disclosure relates to a container for retort food and, more specifically, to a container for retort food, which includes: a ridge portion having a closed curve shape to surround a tray part; and an exhaust hole surrounded by the ridge portion, so that the container enables a lid film to be automatically peeled off from the ridge portion by means of a steam pressure generated in a food during heating to exhaust steam and can be used for retort food which is stored at room temperature.

A cooking bag and a method for cooking food using a cooking bag, with the cooking bag having a variable opening vent formed from a thinning of the bag material, perforations through the bag, and/or slits through the bag, and a tear-off strip for browning and removal of the food product from the bag.

The disclosure may generally relate to a tank which may include a fluid portion and an expansion portion which may be disposed below the fluid portion. Moreover, a three seal pressure relief cap may be constructed and arranged to allow a user to safely remove the pressure relief cap at any temperature.

The present invention relates to a pressure relief element (11) to be used as an overpressure safety means in devices where a gaseous medium must be rapidly released in case of overpressure, wherein the pressure relief element (11) has at least one notch (9) which is designed as a predetermined breaking point where the pressure relief element (11) breaks at a certain level of overpressure, thereby irreversibly opening an exhaust path for the gaseous medium. The present invention also relates to a pressure relief device of an electrochemical battery, comprising such a pressure relief element and a battery comprising such a pressure relief device.

The present disclosure generally relates to a venting system that includes a lid or base with a center wall that defines a central longitudinal axis, and a total radius that is measured from the longitudinal axis to an outermost surface of the lid or base. The venting system further includes a pressure relief feature that is disposed along the lid or base. The pressure relief feature includes at least a first venting feature defining a thinned region of the lid or base, a venting radius is measured from the longitudinal axis to an outermost extent of the first venting feature, and the venting radius is between about 5% and about 25% of the total radius of the lid or base.

In a fuel cap provided with a breather mechanism, a cap openably and closably covers a fuel filler of a fuel tank. The cap includes a breather passage for communication between the inside and the outside of the fuel tank. The breather passage is provided with a breather valve mechanism and a resonator chamber as a silencing mechanism. The breather mechanism is a valve having a spring capable of retaining a pressure within the fuel tank up to a predetermined pressure.
