Definitions

  • the invemion relates to a telescopic closure for and 53 Field f Search l I l l 222 5 525 520 5 52 canister-like containers, in which the part of the closure projecting beyond the upper base of the container has been kept particularly shallow in order to be able to guarantee a perfect stacking of the containers.
  • these thin walled parts are particularly subject to damage in thecase of aggressive filler goods and frequently lead to stress corrosion and thus to leaks.
  • telescopic closures have been known where a threaded pipe is connected with a container in a different manner and which have a screw cap which can be fastened onto the above mentioned threaded pipe, and where, in the insideof the threaded pipe, there is a telescopic pipe which can be pulled up after the cap is unscrewed in order to make it possible to pour the contents out.
  • These closures have the disadvantage that the threaded pipe must have a certain height, so that the screw cap can be fastened, as a result of which the possibility for stacking the containers will suffer from a negative influence.
  • the task of the present invention is a telescopic closure for can and canister like containers which, in its positioned state, has a particularly shallow constructional height of the part which projects beyond the upper base.
  • this problem will be solved through a lower part of a closure provided with an inside thread and which is to be attached insolubly to the container, and a telescoping pipe provided with the corresponding outside thread.
  • the thread of the telescoping pipe may extend over its entire length or else there may be a thread only at the upper and possibly also at the lower end.
  • a connecting band acting like a hinge, a snap cover, will be attached effectively on the telescoping pipe.
  • This snap cover can be welded together in places with the lower part of the closure, as a result of which the original state of the contents of the container will be guaranteed and, at the same time, the snap cover will be secured against unintended opening during transportation or storage.
  • the welding is accomplished in such a way that, in the case of its first use, this weld can be broken by hand or one can tear it off.
  • special welding flaps have been attached on the snap cover.
  • two radially outwardly projecting tabs are attached at the upper end, effectively sprayed on in one piece.
  • These continuations are developed rigidly in a tangential direction and resiliently elastically in an axial direction.
  • the rigidity in the tangential direction brings about a safe grip in case of screwing in and out, while the elastic resiliency in an axial direction causes these continua tions to be pressed downwards in the case of stacking the containers one above the other.
  • handling is further facilitated through the fact that the inside thread of the lower part of the closure has interruptions with which the core thread, which is guided to the lower edge of the telescopic pipe, engages.
  • FIG. 1 shows a telescopic closure in a retracted condition with the snap cover prior to first opening, in a longitudinal sectional view, taken substantially along line I--[ of FIG. 2,
  • FIG. 2 shows a top view of the closure of FIG. 1,
  • FIG. 3 shows a longitudinal sectional view of the upper portion of the closure taken substantially along III-Ill of FIG. 2,
  • FIG. 4 is a longitudinal sectional view similar to FIG. 1 of a modified embodiment.
  • a closure element 1 has been provided, which can be inserted insolubly into an opening of a container. This can be achieved for example through ramming home into the bent open edge of the aperture.
  • the lower part 1 of the closure has an inside thread 2 into which the corresponding outside thread 3 of the telescopic pipe 4 can bescrewed in.
  • the telescopic pipe has the customary channel with the ventilating opening 5.
  • THe snap cover 7 has been attached at the upper end by means of a connecting band 6 acting like a hinge.
  • the snap cover 7 has welding flaps 8, which in spots can be welded to the upper edge of the lower part 1 of the closure. These welding flaps can easily be torn off by hand prior to the first use of the container.
  • the snap cover 7 may be attached in one piece at the telescoping pipe covering the connecting band 6.
  • the projections 9 are located at the upper end of the telescoping pipe, which are developed rigidly in a tangential direction and elastically resilient in an axial direction. In putting an additional container on top of the first one, these projections 9 are pressed downward and do not impede the stacking of the containers.
  • the telescoping pipe is unscrewed, is pulled upwards by means of a handle 10 up to the stop 11. It is advantageous to attach an outside thread also on the lower end of the telescoping pipe, so that the pulled out telescoping pipe can be safely stopped also in this state.
  • the inside thread part 1 of the closure has interruptions, in which the coarse thread 12 engages, which coarse thread has been guided up to the lower thread 3a of the telescoping pipe 4.
  • a telescopic closure for a container opening comprising: an annular member having a longitudinal bore and means on the annular member for securing the annular member in a container opening; a tubular telescopic neck slidably axially received in the bore of the annular member; means defining cooperating helical internal threading on the annular member and externally on at least an axially short portion of the tubular telescopic neck adjacent the outer end of the tubular telescopic neck for fixing the degree of axial extension of the tubular telescopic neck relative to the annular member; and means for closing the outer end of the tubular telescopic neck, comprising a cover having circumferential skirt means thereon for snapping, sealing engagement with the outer end of the tubular telescopic neck and integral flexible band hinge means connecting a perimetrically short portion of said cover to a perimetrically short portion of said tubular telescopic neck;
  • the telescopic closure of claim 2 further including helical threading on said tubular telescopic neck connecting the firstmentioned and second axially short threaded portions.
  • the telescopic closure of claim 1 further including two laterally opposed tabs projecting generally radially outwardly from the outer end of the tubular telescopic neck, said tabs being substantially rigid tangentially of the tubular telescopic neck and elastically resilient axially of the tubular telescopic neck.
