A recently filed patent (Publication Number: US20230303312A1) describes a container assembly for holding beverages. The assembly includes a collapsible beverage container with a body part that can hold the beverage and a cylindrical neck part with an opening. The container also has a closure that seals off the opening and includes a closure disc, an inner cylindrical part, and an outer cylindrical part. The closure disc has a beverage outlet for dispensing the beverage.
One important feature of the container assembly is a pressure-relief device located at the closure disc or the inner cylindrical part. This device is designed to establish a permanent or reclosable opening through the closure or between the closure and the neck part when there is a pressure difference between the inner volume of the container and the external space that exceeds a predetermined pressure value. This predetermined pressure value is lower than the burst pressure of the container.
The patent also describes various embodiments of the pressure-relief device. For example, it can include a weakened part of the inner cylindrical part that deforms inwardly when the pressure difference exceeds the predetermined value, creating the opening. Alternatively, the device can be an elongated hollow protrusion with a breaking point that establishes a permanent opening when the pressure difference is too high. Other options include a burst plate in the closure disc, a flexible foil with a piercing mechanism, or a valve seat and valve body with a spring.
The patent also mentions a beverage dispensing system that includes the container assembly, a pressure chamber, a lid, a beverage tap, a keg connector, and a tapping line. Additionally, there is a method described for filling and handling the beverage container, as well as a closure specifically designed for the collapsible beverage container.
Overall, this patent presents a container assembly with a pressure-relief device that allows for safe dispensing of beverages by relieving excess pressure. The various embodiments of the device provide flexibility in design and functionality. The patent also includes a beverage dispensing system and a method for filling and handling the container.
