CONTAINER, METHOD AND DEVICE FOR MANUFACTURE CONTAINER Russian patent published in 1994 - IPC

FIELD: containers. SUBSTANCE: container has heat-insulating spherical guard, pan 5 with supports 6, hole, cover 2 with sealing member 3, handles 4. Spherical guard is made from molded foamed plastic 1 reinforced with wire fabric 7 and carcass 8. Foamed plastic 1 is uniformly compressed from inner and outer sides of container and contoured over the whole surface by dense hydroinsulated enclosure 9 from resin and by elastomeric film 10. Edges of hole and widest part of container are contoured by rigid strips 12 and 13 secured on carcass 8. Carcass 8 is formed by tubular arcs and rings positioned in vertical and horizontal planes and rigidly connected one with the other. Carcass 8 is fixed on perforated spherical disk 16, which is secured on pan 5 in spaced relation. Pan 5 is formed as spherical perforated disk. Cover 2 has cylindrical perforated flange 20. Sealing member 3 of cover 2 is formed as resilient plug with side surface conforming with surface of strip 12 of hole. Plug is positioned in hole between cover 2 and disk 18, which is fixed on cover 2 by screws 19. Pan 5 is provided with catch 22 and supports 6 have resilient suckers and spherical bearings 21, which are positioned within suckers and provided with mechanism for withdrawing them from suckers. Strip 13 located on widest part of container is provided with resilient shell 14. Handles are made as screws for fixing strip 13 and shell 14 on carcass 8 outside guard. Method involves filling shell cavity with foamed plastic poured on reinforcement; discharging drainage and removing form upon hardening of foamed plastic; coating it with resin and elastomer; exposing it to uniform compression from the side of form simultaneously with cooling and removing heat from peripheral surface. Device has spherical chambers with common center. Spherical chambers are positioned one within the other so that spherical space is formed. Spherical chambers are hydraulically communicated one with the other. Inner chamber is defined by resilient bulb-shaped wall. Outer chamber is defined by double-walled vessel. EFFECT: wider operational capabilities and enhanced reliability in operation. 10 cl, 6 dwg
