  • a plug is to be made available where the side wall has multiple functions.
  • a plug is to be made available be, its weight, compared to that described above Darning, is reduced again.
  • the opening of the injection mold for manufacture the main element of the plug should be in two up to a maximum of three stages so that the cycle time is significantly shortened.
  • the distance between the inside wall of the container and the outside dimension of the compression spring system be such that the stopper is convenient and light on the Container can be put on, without that Compression spring system is damaged.
  • the top part of the stopper should be a regular, and preferably transparent, surface have which is free of empty spaces.
  • the active zone of the compression spring system should meet the respective requirements.
  • the chamber should be active from above Means can be filled.
  • the guarantee band should preferably be a different one Have color than the rest of the plug.
  • the invention is characterized by the features in the characterized independent claims.
  • Figure 4 shows a side view, partially is cut open axially, one according to the invention Stuffing.
  • Figure 5 shows an axial section through a stopper according to the invention with a holding border 11 and element 12.
  • Figure 6 shows an axial section through a stopper according to the invention with bottom 13 and openings 14, wherein the closure element 10 is not shown is.
  • Figure 7 shows the top view of the embodiment according to FIG. 6.
  • FIGs 8a to 8f show possible forms of Openings 14 in the bottom 13.
  • Figures 9a and 9b schematically show a possible one Type of welding of the surface 7a with the Closure element 10.
  • the table below contains, inter alia, the radii r and the heights h of plugs known in the prior art and a preferred embodiment of the plug according to the invention. Stopper according to figure no. Plug weight (g) Radius (mm) Height (mm) Chamber volume (cm 3 ) 1 5.5 r 1 7.5 h 1 7.25 2.56 2 5.0 r 2 8 h 2 6.5 2.61 3rd 3.5 r 3 7.5 h 3 8 2.83 4th 3.05 r 4 12.4 h 4 3.55 3.4
  • the height h 4 is only about half compared to the heights h 1 to h 3 .
  • the radius r 4 has been increased significantly compared to the radii r 1 to r 3 .
  • the compression spring system 6 with the same length of the individual coil springs has a much larger active zone.
  • the chamber 1 has the advantage that with the same Amount of active agent to be introduced 2 this active Means 2 in the uncompressed state in chamber 1 is included.
  • the sealing and / or retention system 3 has preferably in the shape of an olive, with grooves or slats are possible.
  • This system 3 must meet the required requirements Tightness against liquids, such as water, moisture, Ensure dust or gases, such as oxygen.
  • the lower part of chamber 1 can be realized in two ways: A.
  • the lower part of the side wall 8 is designed as a holding border 11 facing the central axis of the stopper.
  • This holding border 11 is from above placed an element 12.
