The present disclosure concerns process for manufacturing a closed head composite drum assembly, comprising: providing an inner shell defining a material-receiving cavity forming a material-filling opening in the inner shell; rotomolding at least partially a closed head outer drum defining an inner shell-containing cavity, the closed head outer drum at least partially enclosing the inner shell; and forming a bung opening in the closed head outer drum substantially in register with the material-filling opening. It also concerns a double wall closed head drum assembly.

A container has a top and a bottom endcap, a bottle sandwiched therebetween, and one or more bands coupling the top and bottom endcaps and the bottle. The bottle receives therein a flexible bladder. At least one of the top and bottom endcaps has a pair of opposing parallel surfaces, one of which has a protrusion extending therefrom and the other one of which has a recess therein at a location corresponding to that of the protrusion. A valving structure demountably engages with a neck portion of the bottle and has (i) a coupling valve assembly having two channels in fluid communication with the bottle and the bladder for injecting gas thereinto and dispensing liquid therefrom, respectively, and (ii) a twist-lock casing receiving therein the coupling valve assembly and removably coupled to the bottle’s neck portion. The twist-lock casing has a structure for safely depressurizing the bottle.

The present disclosure provides a lid assembly for adjusting internal pressure and a container, including a lid main body. The lid main body is provided with a gas nozzle, a sliding plug cavity, a slider nut, an elastic component and an adjusting assembly. The gas nozzle is configured to mount a gas bottle. The adjusting assembly adjusts a movement distance of a sliding plug in the sliding plug cavity and controls a gas output of the gas nozzle so as to control the content and pressure of gas in the container provided with the lid assembly, and improve a drinking taste of a gas-containing drink in the container. The container for containing the gas-containing drink of the present disclosure can maintain a gas (carbon dioxide) content in the drink, improve the drinking taste, and can be adjusted according to requirements to produce different tastes, being adaptable to different users.

This relates to a rolling water container system that can, in various examples, be used to gather, transport, filter, store and dispense liquids such as water. The rolling water container system according to various examples of the disclosure can provide easier transportation of the water, lifting of the water container or drum, and accessibility to the inside of the drum. Additional features can assist with conservation of water by preventing water leakage from the drum and providing for near-complete emptying of the drum. Further features can include handles with greater mechanical strength.

The invention relates to a container for liquids, such as beverages and oils, comprising a casing enveloped by a shell and a valve for dispensing the liquid from the container. The casing and the shell are, at least locally, positively fixed relative to each other.

The present invention relates to a top chime for a beverage keg. The top chime is configured to be readily removable from the keg, for example to enable recycling of the top chime separately to the keg. The top chime comprises a mounting portion for mounting the top chime to a keg in use, and a mounting element separate to the top chime that is configured to be assembled together with the top chime after the top chime has been moved into a mounted position with respect to the keg to thereby secure the top chime with respect to the keg. The top chime is provided with a mounting element that is configured to engage the mounting portion to thereby secure the top chime with respect to the keg. The mounting element is configured to be assembled together with the top chime by moving the mounting element in a radially inward direction with respect to a longitudinal axis of the top chime.

The invention provides for a container that may include a liquid-holding vessel and a skeleton shell supporting the liquid holding vessel. The liquid-holding vessel may comprise a flexible polymer or plastic material for preventing contact between a liquid stored in or dispensed from the container and the skeleton. The liquid-holding vessel and the closure may be formed from a minimal amount of polymer or plastic. The invention also provides for a connection of a liquid-holding vessel with a fitment to the skeleton shell using ultrasonic means. Further, a skeleton shell with mating features allowing the skeleton shell to be formed with smooth edges is provided.

The present invention relates to a bottom chime for a beverage keg. The bottom chime is configured to be push fitted onto the keg, and to subsequently be removable from the keg, for example to enable recycling of the bottom chime separately to the keg. The bottom chime comprises a plurality of inwardly extending engagement elements that are configured to form a snap fit engagement with a corresponding plurality of recesses provided in the body of the keg.
