Abstract: A lid-container assembly made of synthetic plastic material suitable for the transportation and storage of hazardous materials in conformity to the UN standard. The container includes a bottom and a substantially cylindrical or cone trunk side wall having an upper edge that bounds an access opening. The container is provided with a first external annular strip provided with a first circular rib and with at least one second circular rib for snap fitting of the lid. The lid includes a central part and a peripheral wall that conforms to the side wall of the container and further includes a second external annular strip that releasably engages the corresponding external annular strip of the container. The second external annular strip has an upper annular element that connects to the peripheral wall by an upturned U-shaped upper annular channel, and includes a lower annular element inserted into a lower annular channel in the form of an upwards pointing U, and an intermediate annular element for tear opening.

Abstract: It is described a method and an apparatus for injection co-mould and assemble plastic material objects having a first part provided with a hinge pin, and a second part provided with an annular element suitable to be coupled in an articulated manner. The apparatus includes a mould having separated moulding impressions for the two parts to be moulded; a first moulding pin element defining the pin impression and a second moulding pin element defining the annular element impression are provided. The apparatus includes cooling means; particularly the first pin element is internally provided with a channel and a tubular element, being coaxially arranged and defining a cooling gap. A cooling fluid flows through the tubular element and the gap. Cams are provided which axially move the pin elements to cause the automatic assembly of the object during the mould opening and then to allow extracting the moulded object.

Abstract: A garment can have an upper body section. The upper body section of the garment can have a stretchable portion. A spring constant ratio of the stretchable portion to the garment material may be at least about 1.0. The percent set ratio of the stretchable portion to the garment material may be less than about 1.0. The garment may also have a lower body section. The lower body section of the garment may have a fit panel. The spring constant ratio of the fit panel to the garment material may be less than about 1.0.

Abstract: An article of clothing may have two side panels in a torso section of the article of clothing. In a closed configuration, one of the side panels may overlay the other side panel. The article of clothing may also have a lower body section adapted to pass between the wearer's legs when the article is in a closed configuration.

Abstract: Method and apparatus for injection co-molding and assembling of articles made of plastic material, the articles having a first part provided with a hinge pin, and a second part provided with an annular element designed to be connected to each other by hinging. The apparatus includes a mold having separate mold cavities for two parts of the article to be produced; a first molding member, defining the mold cavity of the pin, and a second molding member, defining the mold cavity of the annular element, are axially movable and operatively connected to cam control elements forming part of the same injection mold. The cam control elements are shaped and arranged to cause, after the opening of the mold, the automatic assembling of the plastic article, via a selective sequence of axial movements of the two molding members, during the demolding step of the molded article.

Abstract: A pneumatic valve device (17) for ejecting, by pressurised air, moulded articles (16) in plastic material from a cavity of a mould (10, 11); the valve device (17) comprises a valve body (18) having an air feeding chamber (34) connectable to a pressure air source, and a spring-biased pressure-actuated valve member (20, 21). The valve member comprises a valve head (20) having fore and side surfaces (30, 27), and a stem (21) rearwardly extending from the head (20); an air flow path (32, 33) is provided in the valve member from the rear end of the steam (21) to at least one exit hole (33) on the side surface (27) of the valve head (20). The valve member (20, 21) is axially movable between a retracted position into a seat of the valve body (18), in which closes the flow path (32, 33), and an advanced position in which the valve head (20) protrudes into the cavity of the mould (10, 11).
