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.

A keg includes a container 1 and a chime 3 fixed to each other by means of an adhesive. The container has a peripheral side wall 4, and a top wall formed with a central neck containing a valve fitting provided with a dip tube which extends into the container. A bottom wall 9 is formed with a central projection 10 defining an internal well inside the container which receives the lower end of the dip tube. The chime 3 has an inner hub 12 with a central opening 13, legs 14 which extend outwardly from the inner hub, and an outer skirt 15 joined to outer ends of the legs 14. The central opening 13 of the inner hub 12 receives the central projection 10, without fixation, to locate the inner hub against lateral movement. The central opening 13 may have the same internal profile as the outer profile of the central projection 10. In a modification the central opening 13 incorporates a plurality of slots which radiate outwardly to define a plurality of flexible inwardly-directed fingers which locate the inner hub and accommodate variations in the relative axial position of the central projection 10 and the inner hub 12.

The present disclosure provides a chemical container and a method for manufacturing the same. The chemical container comprises a head portion having a top wall and a head sidewall extending from an edge of the top wall, as well as a body portion jointed with the head portion and defining a chamber together with the head portion. The top wall has a mouth structure configured for one or more pipelines to pass through and connect with the chamber. The manufacturing method is simple and of low cost, and the resulted chemical container is able to withstand a greater internal pressure and is configured to collect any leaking liquid chemicals.

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.

An overpack salvage drum including a drum body and a lid. A bottom wall and side wall of the drum body cooperate to define an interior of the drum body. The lid is configured to close an open top of the drum body. The lid includes at least two independent lid threads to engage with corresponding independent drum threads provided on the drum body. The lid includes a plurality of alternating castellations having a flat inner facing side and castellations having an arcuate inner facing side, which can be interdigitated with castellations on another lid when two lids are stacked together, or can be used to lock with a drum body to rotationally secure a drum body relative to the lid when in a stacked arrangement. The lids include lugs and recesses, or rings that allow for secure stacking of the lids.

An over pack drum for storing hazardous materials includes a cylindrical main body extending between top and bottom ends, the cylindrical main body defining an open channel wherein each of the top and bottom ends of the cylindrical main body are open-ended; a top cover being configured for coupling with the top open end of the cylindrical main body; a bottom cover being configured for coupling with the bottom open end of the cylindrical main body; and a plurality of roller ball and bearing assemblies partially embedded within the bottom cover such that a portion of each of the roller balls extends beyond the upper facing surface of the bottom cover for permitting multidirectional movement of a container moved thereon.

A container includes: a skeleton shell defining a container body of the container, the skeleton shell being formed from a recycled and/or biodegradable pulp material; and, a bag or liner removably disposed within the skeleton shell. Wherein the skeleton shell includes at least one separation feature that facilitates separation of the skeleton shell from the bag or liner.

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 separable container including a top and a base joined by a locking ring, the top and the base attached to the ring through locking tabs adapted to sealingly attach the top to the base through the ring. The base is of a converging shape allowing bases to be nestled within each other when separated from the top for easier transport when empty. When assembled the container typical includes a bladder to hold a liquid to be dispensed and a pressuring means enables the liquid to be dispensed.

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.
