Definitions

  • the present invention relates to a closure device for collapsible tubes comprising a closure cap screwed on to the neck of the tube and an outlet valve subject to spring pressure seated on the closure cap and adapted to be opened upon pressure exerted on the tube owing to. the displacement of the contents thereof, for the purpose of permitting the desired amount of the contents to leave thetube.
  • an additional valve is combined with the outlet valve, this additional valve being seated on the neck of the tube, and
  • the additional valve is in its open position so as to admit the outlet valve to be pressed open; on the other hand, when the closure cap is rotated in the unscrewing direction and the outlet valve is accordingly displaced, the additional valve is enabled to be brought to its closing position.
  • closure according to the invention It is an important advantage of the closure according to the invention that it remains out of contact with the contents of the tube until the tube is used for the first time; this is due to the fact that the additional valve is brought to its closing position. Accordingly the closure re-: mains in properworking condition even when the 4 tube has been kept in store for a substantial :0 time. Thisis not always the case withthe hitherto known tube closures into which when the tubes are filled, part of the contents will penetrate, and when the tubes are kept in store for a relatively long time the closure will be stuck together by :1 this part of the. contents becoming hardened.
  • Figures 1 and 2 show partly in section and partly in elevation, at an enlarged scale a tube, the closure of which is shown in two different positions respectively, and
  • Figure 3 is an axial view of the tube from which certain parts of the closure have been removed.
  • the tube body a is provided with an externally threaded neck a on which a closure cap b is screwed; the upper edge of this cap forms a valve seat b for the outlet valve 0.
  • An additional valve 11 is provided below the valve 0 and seated at a in the tube neck a In this manner a kind of double valve is provided for the tube closure comprising a common valve rod e, on the upper end oi-which the valve 0 is slid with a tight fit, by means of an extension sleeve c provided on a the valve 0.
  • a screw spring h tending to displace the valve rod e downwardly and to apply the valve 0 to its seat b is provided on the valve rod e between a shoulder of this rod and a.- cross-bar f forming an abutment, which is supported against an internal shoulder of the closure capb and 5 through which the valve rod e passes.
  • Two oppositely extending ribs i are provided at the lower end portion of the valve rod e and arranged to engage slidably vinto twocorresponding guiding grooves i ( Figure 3) formed in the inner surface 1 of the tube neck 0 in order to provide a reliable uide for the valve rod e during its displacing movements.
  • the closure. cap b may in addition be screwed upwardly so as also to press the valve d 50 to its seat in the above described manner, thus sealing the tube twice.
  • the latter is, provided at its lower circumference with corrugations k.
  • a closure device for collapsible tubes comprising a screwthreaded tube neck, a closure' closure and opening of the inner valve when.
  • valves are rigidly connected by a common shaft, a spring being mounted on the latter between an abutment thereof and an abutment member provided inside said closuresleeve.
