Abstract: The present invention relates to a method for the manufacture of pressure-resistant gas and/or liquid tight containers made from thermoplastic materials. To this end the method comprises the following steps: providing a removable external mandrel around a neckpiece, followed by providing at the inside of such mandrel a thermoplastic material for the manufacture of a thermoplastic internal wall. Hereupon the external mandrel is removed and the thermoplastic internal wall is filled with a cooling liquid. Hereupon additional thermoplastic material is provided to the external side of the thermoplastic wall and is consolidated either during the provision hereof, or thereafter or both. Hereupon the cooling liquid is removed and the container is ready for being used.

Abstract: A method of manufacturing a custom sized plastic tote lighter in weight than heretofore known custom sized plastic totes is provided. The method comprises separating an injection molded tote into upper and lower portions by cutting the injection molded tote. A sleeve or middle portion of plastic material is secured to the upper and lower portions of the injection molded tote to create a custom sized plastic tote of a desired height. Alternatively, portions of different injection molded totes may be used to create a custom sized plastic tote. The sleeve may be made from different materials and may be made of multiple pieces.

Abstract: A structure is injection molded onto a group of panels to form a container. The container has a tray and an injection-molded feature. The tray has a plurality of side panels that extend at least partially around, and at least partially define, a cavity of the container. The tray has a plurality of multi-part flanges with at least one of the multi-part flanges including a lower flange portion and an upper flange portion. The injection-molded feature has band that is injected molded onto the lower flange portion and the upper flange portion. An injection-molded strip extends along and at least partially defines the corner of the container. The strip extends downward from the inner portion of the band in the elongate corner of the container. A tool is also disclosed for forming the container.

Abstract: Containers suitable for use in food cooking, food serving and food storing are disclosed.

Abstract: Flat or semi-flat element (1) including a partly or completely circumambient frame (2), which element (1) is manufactured through molding of a polymeric material. The element (1) includes a carrying structure, constituted by the frame (2), and an intermediate wall section (3). The wall section (3) is connected to the frame (2) via a resilient section (4), the resilient section (4) being a part of the wall section (3). The differences in the temperature related shrinkage between the frame (2) and the wall section (3) is absorbed by the resilient section (4), whereby warping of the element (1) is avoided.

Abstract: Disclosed herein is a high strength container particularly suited for containing heavy materials and being stacked when fill and nested when emptied. The container includes a receptacle having tapered upright walls that are capped by a lid. The receptacle has an abruptly enlarged upper perimeter joined to a lower perimeter by a horizontal ledge, which resists bulging of the walls under heavy loading. The lid has grooves at stacking support surfaces in which reinforcing members are disposed. The reinforcing members can include winged saddles to disposed in indentations in the lid that are designed to better distribute loads through the receptacle.

Abstract: A method of rotationally molding a part to include a platform therein is provided. The method includes providing a mold and mounting the platform adjacent to, and preferably connected to the wall of the mold. Resin is deposited in the mold and the mold is closed. The mold is heated and rotated around at least two axes. The molten resin substantially covers the interior wall of the mold and the portion of the platform exposed therein. Rotation continues as the mold is cooled whereby the resin solidifies into a self-sustaining configuration. The resulting part is removed with the platform receiving resin thereon incorporated in the part resulting in a reinforcement oriented in spanning relationship to an interval defined by spaced-apart regions on the mold wall. The placement of the platform may be selected, whereby the resin and platform provide structural reinforcements for the part, lifting points incorporated into the part, or electrical grounding sites which are formed during molding.

Abstract: A pressure vessel insert comprises a plate having an outboard surface and an inboard surface interconnected by outer edge surfaces, and defining an aperture extending therethrough from the outboard surface to the inboard surface. The plate is provided with a modulus of elasticity within about 30% of a first modulus of elasticity of inboard and outboard skins of a wall portion of the pressure vessel shell around an opening in which the insert is disposed, in directions through the thickness of the skins.

Abstract: The top (2) of a sheet metal container (1) for the transportation and storage of liquids has a central fill opening (3) which is edged by a neck (5) which is perpendicular to the top surface (4) of the container. A plastic or metal ring (6) with an external thread (7) is pressed down against the top surface (4) by the upper edge (8) of the neck (5). The neck is swaged outwardly. The threaded ring (6) is protected against rotation by form-fit connections on the neck (5). A plastic screw cap (11) into which a disc-shaped insert (12) of special steel is pressed, is screwed onto the threaded ring (6). Between the outside edge (13) of the cap insert (12) and a ring projection (14) of the latter, an annular groove (15) for holding a gasket (16) is molded into the insert, and by this gasket (16) the screw cap (11) is sealed against the upper edge (8) of the neck (5).

The inserts are located on the outer perimeter of the skirt and determine the flow of water from the cover to the ground. A pre-molded gasket extends about the interior perimeter of the cover. The gasket seats on the skirt assembly and seals the fuel containment device from the atmosphere. The cover is bolted to the fiberglass skirt and forms a drainage channel between the cover and the skirt.
