A pipe connectable plastic bucket includes a bucket and at least two quick-connect devices. The bucket has a plurality of through holes for communication between the inside and the outside of the bucket. The at least two quick-connect devices respectively correspond to the plurality of through holes, and are disposed on the bucket. The at least two quick-connect devices are adapted to connect to pipes, and are used for allowing a fluid entering and exiting the bucket through the plurality of the through holes. The at least two quick-connect devices comprise a first quick-connect device for allowing the liquid to enter and to exit the bucket. The present invention also provides a method of using the pipe connectable plastic bucket.

Methods and systems for integrating multiple portions of a container are provided. The method and system are specifically designed for integrating multiple shell portions with ear lobe-shaped tabs. The method comprises: providing a first set of retention structures to be associated with a plurality of inter-connecting features formed on an edge of a first shell part, wherein the first set of retention structures comprise at least a lead-in feature and a retention feature; providing a second set of retention structures to be associated with a plurality of inter-connecting features formed on an edge of a second shell part, wherein the second set of retention structures comprise at least a deflection feature and a retention feature; and engaging the two shell parts with aid of the retention structures.

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 invention relates to a container (10) which is produced in a blow molding process and is made of thermoplastic material—preferably a bung drum—having a welded-on bung connector, prefabricated in an injection molding process and having an internal thread, for the storage and transport of liquid or free-flowing contents. In order to eliminate disadvantageous material distortion in blow-molded containers as a result of relatively long cooling times of thick locations, e.g. at threaded bungs and flash seams, according to the invention formed in the top (30) of the container (10) is a shortened welded bung connector (32), onto which a solid threaded welding head (12), prefabricated in an injection molding process and having an internal thread (20), is welded.

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 invention relates to a closed-head drum (10) with inserted thin-walled inliner (22) of multilayer plastic film for storing and transporting liquid or free-flowing filling materials. In order to improve the use of liners in closed-head drums, and to facilitate in particular the handling for the users such as the filling and emptying operators, so as to allow the closed-head drum (10) with liner (22) to be handled in precisely the same way as a closed-head drum without a liner, the present invention provides for the liner surface to adhere, or be adhesively bonded in a detachable manner, to the inner wall of the drum by virtue of a vacuum being created in the intermediate air space between the inner wall of the drum and liner surface and by thermal activation by means of hot air injection into the interior of the inliner.
