Definitions

  • the invention relates to a tube with a screw cap with a tear-off membrane connected to the tube opening, in which the tear-off membrane has at least one tear-off tab for pulling the membrane off the tube opening.
  • Tubes of the type mentioned at the outset have become known, for example, from German utility model G 9002262.9 or EP-B 323 370.
  • the tear-off membrane which is designed differently in each case, serves as a guarantee closure and is intended to ensure that the filling quantity and filling status of the tube contents have remained unchanged even when the screw cap has been loosened.
  • the known tear-off membranes generally consist of easily plastically deformable material and in particular of aluminum foils, which have a plastic coating on their side facing the tube mouth for the purpose of hot gluing or welding to the edge of the tube opening.
  • tear-off tabs have already been proposed.
  • the functional reliability of such a tear-off tab is only guaranteed if the tear-off tab cannot be sheared off or destroyed when the tube is screwed on or when the screw cap is placed on the tube.
  • the invention now aims to provide an embodiment of the type of a tube with screw cap mentioned at the outset, which can be used in any conventional tube with screw cap without complex post-processing and in particular without complex redesign of the tubes and in which tear-off membrane with a correspondingly long and easy to gripping tabs can be used, which are not damaged when screwing on a screw cap.
  • the training according to the invention with existing shapes should be minimal Effort for adaptations can be continued and the possibility is created to prevent the risk of damage when accommodating the tab.
  • the design according to the invention essentially consists in the tube neck carrying the external thread for the screw closure having at least one recess or groove extending in the axial direction.
  • the external thread has at least one recess or groove extending in the axial direction, a correspondingly long free space is formed for a correspondingly long tear-off tab and the possibility is created to accommodate the tab in a protected manner on the tube neck.
  • a design can be implemented with very little effort using existing molds, it being sufficient to adapt existing molds by inserting a corresponding strip for the production of such grooves. It can therefore continue to be used with the existing set of shapes after slight adaptation. The subsequent arrangement of such grooves by hot deformation does not pose any significant problems.
  • the design according to the invention makes it possible to maintain the usual thread configurations and dimensions and to continue to use the usual screw caps unchanged. All known process steps for sealing or welding or gluing the film to the edge of the tube opening can thus also be used unchanged, with the additional advantage that an easily detectable and not easily damaged tear-off tab can be safely accommodated.
  • the design is advantageously made such that the depth of the recess or groove in the radial direction essentially corresponds to the depth of the grooves of the external thread.
  • FIG. 1 shows a view of a tube according to the invention with a screw cap, the screwed-on screw cap being shown in section; 2 shows a plan view of the embodiment according to FIG. 1 with the screw cap removed; and Figure 3 shows a partial section along the line III-III of Figure 1.
  • 1 denotes a tube, an external thread 2 being provided on the tube neck, on which a screw cap 4 provided with a corresponding internal thread 3 can be screwed on.
  • the tube opening 5 is closed with a tear-off membrane 6, the tear-off membrane 6 having a tab 7.
  • the tear-off tab 7 is arranged in a recess 9 extending in the axial direction of the tube neck 8, the depth of the recess or groove 9 in the radial direction essentially corresponding to the depth of the grooves of the external thread 2. In this way, when the screw cap 4 is screwed on, the tear-off tab 7 can be accommodated in the groove 9 without risk of destruction.
  • the tear-off tab 7 extends, for example, up to the inclined tube extension 10, so that it can be easily gripped and the tear-off membrane 6 can be easily removed before the tube is used.
  • the screw cap 4 has in its inner area, for example, extensions or a circumferential projection 11 which, when the screw cap 4 is screwed on, presses the tear-off membrane or film 6 against the surface of the tube neck 8 which has the tube opening 5.
