A process of manual, semi-automatic and fully-automated integration of discrete components into a container that results in fast, reliable, cost-effective, and scalable production of composite containers is disclosed. The process can be embodied in manufacturing equipment that has a series of stations and may be called an assembly device. The equipment can produce containers, tubs, canisters, cartridges, etc. which are easily separated into different bio-degradable or compostable parts. Other container types are possible and are contemplated.

Disclosed is a method for manufacturing gas cylinders. The disclosed method for manufacturing gas cylinders comprises: a) a step of producing a liner using a liner blower machine; b) a step of applying an adhesive to the threads of the produced liner; c) a step of coupling a bushing to the threads of the liner; d) a step of leaving the liner having undergone step c) for 30 minutes to 2 hours at room temperature so as to naturally harden the adhesive; e) a liner-flaming step of heat-treating the outer surface of the liner with plasma; f) a step of coupling a shaft to the liner; g) a winding step of mixing multiple fiberglass strands with a resin and a hardening agent, and wrapping the mixture around the outer surface of the liner; h) a dry-hardening step of drying the cylinder made of the composite material and having undergone the winding step for 70 to 90 minutes at a temperature of 70 C. to 90 C.; i) a cooling step of leaving the cylinder made of the composite material for 15 to 40 minutes at room temperature so as to lower the surface temperature of the cylinder having undergone the dry-hardening step to a level of 35 C. or lower; j) a step of separating the shaft from the cylinder made of the composite material; k) a step of assembling a valve to the bushing installed in the cylinder made of the composite material; and l) a step of checking the state of the gas cylinder including the cylinder made of the composite material.

A method for forming a container with an integral handle includes heating a preform having an integral handle in a first oven, stretching the preform, closing a first mold having a first mold recess and a second mold having a second mold recess around the preform, and blowing air into the preform. A handle pocket wedge block is inserted into a handle pocket of the integral handle of the preform within the first mold and the second mold.

The invention provides a synthetic resin container with a plurality of handgrips on its top face and a manufacturing method for such a container. The plurality of handgrips, as well as a metal cap opening, are molded in advance as insertion components. After heating the fusion portions of the insertion components, the insertion components are disposed parallel to the direction in which a parison is to be placed. Thereafter, a parison is placed into dies, and the dies are clamped. Air is blown into the parison through the metal cap opening to fuse the parison and the insertion components.

A hinge mechanism includes a resin base member, and a support rotatably and pivotally mounted to the base member. The base member is formed by blow molding so as to be hollowed. The base member integrally includes a hinge member for rotatably and pivotally mounting the support to the base member. The hinge member is set in a molding die for clamping at the time of the blow molding of the base member, so as to be molded integrally with the base member.

The present invention relates to a method of producing a plastic container (24) comprising the steps of producing a base element (21), parison or preform, inserting magnets (44) in a cavity (52) of an open blow-moulding die (54), inserting the base element in the open blow-moulding die, and closing the die and introducing air into the base element for forming the container in the die, whereby the magnets are integrated in, and are attached to, the formed container. The present invention also relates to a container produced by the method.

A blow molded article of manufacture includes first and second battery enclosures each having respective first and second laterally outward extending flanges, and a parison made of a polymeric material. The first and second battery enclosure components are disposed facing each other and with their respective first and second laterally outward extending flanges registered with each other and spaced apart from each other by an offset. The parison is sandwiched between and connects together the first and second battery enclosure components, such that the parison conforms with interior surfaces of the battery enclosure components and with the parison substantially filling the offset. The article of manufacture may be cut along a cut line through the parison and within the offset around an outer perimeter of the article of manufacture, thereby separating the article of manufacture into first and second battery enclosure assemblies. Methods of formation are also disclosed.
