The invention discloses a locking structure of a cup. The locking structure comprises a cup body and a cup cover. The cup body is provided with a first buckle, and the cup cover is provided with a second buckle adaptive to the first buckle. The locking structure further comprises a lock catch which is movably arranged on the cup cover up and down. The lock catch is provided with a bolt. Correspondingly, the cup body is provided with a bolt hole adaptive to the bolt. The cup cover rotates on the cup body, so that the first buckle and the second buckle are matched. When aligned, the bolt falls into the bolt hole, thereby realizing rotary locking.

A thermally insulating beverage jacket is provided. The thermally insulating beverage jacket includes a first flexible tubular-shaped portion having first and second surfaces disposed opposite to one another. The first surface defines a first interior region with a first diameter in a first operational position of the thermally insulating beverage jacket. The first flexible tubular-shaped portion is centered about a longitudinal axis. The thermally insulating beverage jacket includes a second flexible tubular-shaped portion coupled to the second surface of the first flexible tubular-shaped portion and having at least first and second air gaps therebetween in the first operational position of the thermally insulating beverage jacket.

The present disclosure provides methods for stabilizing a colloidal dispersion during transport for low defect tolerance applications. The methods involve eliminating fluid interfaces within a dispersion, storing the dispersion in an environment of inert gas, and degassing the dispersion. Several bottle closure devices are described which may be ideal for use with these methods, being able to seal a container filled with a dispersion, permit the removal of headspace and rapidly empty the contained dispersion. In one aspect, the device includes a vented cap and semi-permeable membrane, which allows the passage of gas into and out of the container, and a dispenser nozzle integrated with the device to allow a stored dispersion to be dispensed without removing the device from the container. In another aspect, the bottle closure device includes an attachment point for a removable downtube and dispenser nozzle.
