  • the aforesaid portion of the projection 14 of the cover 6 which penetrates into the groove 12 of the frame 4 is arranged to have no contact with the walls of the groove, so that the lower edge 16 of the projection 14 of the cover and part of the two lateral faces of the projection, which are contiguous to said edge 16, are immersed in the substance 15.
  • the device 1 comprises sealing means 17 which cooperate with the frame 4 and the cover 6, when the latter is fitted into the frame, and which are arranged, all over periphery of the device, to prevent any passage, towards the substance 15 present in the continuous groove 12, of the aforementioned liquids and solids which would be introduced into the gap 18.
  • sealing means 17 are advantageously fixed to frame 4, as shown in the drawings, in the zone of said frame which is delimited by the upper face 8 thereof and the maximum level that the substance 15 can reach on the wall 19 of the groove 12 which is closest from the periphery of the frame 4.
  • the sealing means 17 are constituted by a continuous tongue 20 which is made of an elastic and impermeable material, such as rubber, provided in the groove 12, the edge 21 of this tongue 20 is trapped , to be immobilized therein, in the frame 4 so that the said tongue projects into the groove 12 of the frame over a distance greater than the distance which separates the wall 19 from the groove of the face 22 of the projection 14 of the cover 6 coming in look of this wall 19 when the cover is fitted in the frame and this, so that this face 22 of the projection 14 compresses the free edge 23 of the tongue 20 to seal said groove, to liquids and materials solids which could be introduced into the gap 18, in its zone which is between its wall 19, the tongue 20, the face 22 of the projection 14 of the cover 6 and the upper level of the liquid or viscous substance 15 above.
  • a continuous tongue 20 which is made of an elastic and impermeable material, such as rubber, provided in the groove 12, the edge 21 of this tongue 20 is trapped , to be immobilized therein, in the frame 4 so that the said tongue projects
  • the frame 4 comprises, combined with the above-mentioned groove 12, a second continuous groove 24, also horizontal and located below the level of the cover 6, the opening is turned towards the lower face 13 of the latter.
  • This lower face 13 of the cover 6 has, in addition to the above-mentioned projection 14, a second continuous projection 25 which is intended to penetrate into the groove 24.
