  • the wall 19 of the container 1 can, without departing from the scope of the present invention, be provided with other means of retaining the seal 13 in the compressed condition.
  • a tank devoid of cavities 23 does not is not beyond the scope of the present invention.
  • peripheral chamber 11 The dimensions of the peripheral chamber 11 are chosen so that they can accommodate the seal 13 in the condition not compressed (open container) and the seal 13 as well as the compression means 15 in the compressed condition (closed container).
  • the means 15 for compressing the seal 13 comprise a rod 15.2 introduced into the peripheral chamber 11 by an opening 25 extending over a short length of the wall 11.2.
  • the rush 15.2 has good axial rigidity while being flexible perpendicular to its axis to be able to follow the curvature of the chamber device 11.
  • the end of the rod 15.2 is provided with gripping means 27, for example a handle.
  • gripping means 27 for example a handle.
  • the opening of the can 1 can only be obtained by removing of the rod 15.2 of the chamber 11 and, consequently, the tearing of the cover forming a tamper-evident device.
  • the rod 15.2 can be supported directly on the joint 13 or, via an intermediate piece, for example a rigid washer 15.1.
  • the rigid washer 15.1 and / or the rod 15.2 advantageously have a low coefficient of friction.
  • the washer 15.1 can be incorporated into the gasket 13 and / or the rod 15.2.
  • FIGS. 4 and 5 we can see two variants of embodiment comprising a seal 13 pushed radially by the rod 15.2 in direction of the cavity 23 of the wall 19 of the container.
  • the rod 15.2 can, as illustrated in FIGS. 4 and 5, bear directly on the gasket 13 or lean on an intermediate elastic piece (not shown), by substantially cylindrical example.
  • the intermediate piece allows to reduce friction between the rod 15.2 and the seal 13.
  • the joint 13 has a section in the form of, (comma) when it is not compressed.
  • the rod 15.2 rests on the convex part of the joint 13 which it deforms and presses the portion of the originally concave joint 13 in the concavity 23 of the wall 19 ( Figures 4b and 5b).
  • the chamber 11 has a lower wall 11.1, a wall cylindrical 11.3 and a sloping upper wall 11.2 '.
  • the opening 25 of introduction of the rod 15.2 is located at the junction of the walls 11.3 and 11.2 '.
  • FIG. 4 includes a chamber 11 comprising an upper wall 11.2 parallel to the wall 7, a cylindrical wall 11.3 and a sloping lower wall 11.1 '.
  • the opening 25 of introduction of the rod 15.2 is provided at the junction of the walls 11.3 and 11.1 '.
  • FIG. 8 a tubular joint 13 can be seen.
  • FIG. 9 one can see a tubular joint 13 whose the central recess is filled with 13 'foam, for example with cell closed.
  • the seals 13 are advantageously made of elastomer whose hardness is for example equal to 70 Shore A.
  • the seals 13 can be produced by molding or by extrusion and welding. They can be provided with a weakening of the section on the surface facing the wall 11.3 of the peripheral chamber 11, of so as to facilitate compression. However, such a notch decreases also the restoring forces ensuring the passage in non condition compressed ( Figures 2a and 2b) when removing rod 15.2 from the chamber peripheral 11.
  • the surface of the seal 13 can be provided with teeth locally increasing the pressure exerted on the surface of reception delimiting the opening to be closed.
  • rods having an I-shaped, trapezoidal section, square or rectangular does not depart from the scope of the present invention.
  • a plurality can be used, for example, two rods, whose total length is substantially equal to the perimeter of the peripheral chamber 11.
  • the container 1 and the cover 5 are advantageously made sheet metal. It is understood that the implementation of joints in other materials, in particular plastomer or mixture of elastomer and of plastomer is not outside the scope of the present invention.
  • Canister 1 is filled, for example, with painting.
  • the peripheral chamber 11 of the cover 5 is lined with a seal 13 advantageously supplemented by a washer 15.1.
  • the cover 5 is placed on the container 1.
  • the opening 25 and along the arrow 31 introduce the rod 15.2 in the peripheral chamber 11 of the cover 5.
  • the rod 15.2 a substantially the same length as the peripheral chamber 11.
  • the flexibility of the rod 15.2 guided by the chamber 11 allow the joint to be crushed 13 over substantially its entire length.
  • One end of the rod 15.2 protrudes of the opening 25 to allow the opening of the can 1.
  • one places a tamper-evident seal around the rod 15 and the periphery of opening 25 (not shown). It should be noted that the introduction of rod 15.2 in the peripheral chamber 11 is an easily automated operation.
  • the user wishing to open the can 1 pulls on the end visible from the rod 15.2, for example on the handle 27 according to the arrow 33.
  • the seal 13 takes up the uncompressed form illustrated in FIGS. 2a, 3a, 4a and 5a allowing effortless removal of the cover 5.
  • the can 1 can be closed several times by fitting the cover 5 and by new introduction, this time manual, of the rod 15.2 according to arrow 31.
