Definitions

  • the invention relates to a closure with one or more lid parts for containers holding radioactive or toxic substances.
  • Containers with one or more closure parts having a closure are known in practice in a wide variety of designs. For containers with several lid parts there are container closures with two separate lid parts and container closures with two interconnected lid parts. All known container closures have in common that they are attached to the container directly or indirectly by screwing means.
  • the present invention has for its object to provide a closure of the type mentioned, in which expensive fasteners are unnecessary, but without compromising security.
  • each cover part is attached to the container by means of its own snap ring and that the cover part, in the case of several cover parts the outer cover part, has a plurality of plug bolts distributed over its circumference to secure its snap ring.
  • the invention provides a container closure which is adequately secured for various uses of the container and which can be handled quickly and easily, which makes it particularly suitable for remote handling due to security.
  • the socket pins are longer than the holes provided for them in the cover part and have a recess which is flush with a recess in the outer cover part when the socket pin has a position in which its lower edge lies on the level of the lower edge of the cover part.
  • the lid closure according to the invention can be handled particularly quickly and easily by these measures.
  • the inner lid part is provided with a truncated cone-shaped bulge, which further simplifies the container closure due to the omission of special recesses or moldings for the snap ring.
  • the container has a seal 2 on its upper end face.
  • the container has an annular groove 3 and 4 on its inner peripheral surface and also on its outer peripheral surface.
  • a snap ring 5 which consists of spring steel wire with a round cross section and which is slotted at one point.
  • the snap ring 5 protrudes about half from the annular groove 3.
  • the lid part 6 is provided with a truncated cone-shaped bulge 7 and is supported with its edge on the seal 2 when used in the container 1.
  • the Socket pin 10 Before and when placing the outer lid part on the container 1 are the Socket pin 10 in a position as shown in FIG. 2.
  • the socket pins 10, which are longer than the holes 9 provided for them, have a recess 11 which, when the socket pins have the position shown in FIG. 2, in which their lower edge lies on the level of the lower edge of the outer cover part 6, aligned with the recess 8 and also with the groove 4.
  • a snap ring 5 which consists of spring steel wire with a round cross section and which is slotted at one point.
  • this snap ring 5 protrudes about half from the recess 8 and into the annular groove 4.
  • the ring 5 protrudes approximately half into the recesses 11 of the plug bolts 10.
