Definitions

  • the present invention relates to a tank with variable capacity for vinous products or any other similar products, especially products which deteriorate in contact with air, of the type which includes a floating cover and a flexible seal between the cover and the wall of the tank.
  • the tank with a cylindrical wall has a lid floating on the contents, having a housing around the entire circumference.
  • This housing represents in cross section a rectangle open towards the outside, that is to say, on the side of the wall of the tank, in this housing there is an inflatable seal. When it is inflated, it is retained by the three closed sides of the rectangle and develops towards the wall of the tank on which it comes to press and thus create the seal on either side of the cover. With such a seal, we are forced to deflate the seal each time, draw up the desired quantity and then re-inflate the seal.
  • the present invention aims to remedy these drawbacks.
  • the invention as characterized in the claims solves the problem of creating a tank with a cylindrical wall or the like, provided with a cover intended to float on the contents of the tank, this cover comprising a seal over its entire circumference , compressing against the wall of the tank and sealing on either side of the cover when the level of the contents of the tank is fixed, decompressing itself enough to slide along the wall and allow the cover to descend when the level of the contents of the tank goes down and recompresses itself against the wall, again ensuring the sealing on either side of the cover when the level of the contents of the tank has become fixed again, this descent level can be renewed at will.
  • the tank designated as a whole by the reference 1 has a cylindrical wall, the output of the content is provided by the orifice 15 which can be opened and closed at will by a valve or any other means suitable for the product to which the tank is intended to contain.
  • a cylindrical cover designated as a whole by the reference 2 intended to float on the contents of the tank, the outside diameter is provided to cover as much as possible the surface of the contents without however being hampered in its lowering through the wall 16 of the tank and the bottom 17 of the cover will if possible have the same configuration as the bottom 18 of the tank, flat or curved for example, although this is not necessary, it has an inner rim at its upper part horizontal 12 for receiving a joint designated as a whole by the reference 3.
  • the tank 1 and the cover 2 will be made with resistant materials and suitable for the product for which the tank is intended to contain, for example: stainless steel, aluminum, polyester.
  • the metal-plastic joint ref.3 mainly made in particular of suitable static material, for example rubber and of more resistant but flexible material, for example spring steel, stainless steel with spring, fabric, has in its cross section the shape of a V lying whose tip 7 in the free state is rounded (as can be seen in Figure 2) and turned towards the wall of the tank, the two openings 8 and 9 deviate from one of the other from the horizontal plane passing through the middle of the rounding 7.
  • the upper opening 8 is secured to a ring 11 made of metal or any other material which can fulfill the same conditions, although this ring may not be necessary if the resistance of the seal at this point is sufficient to perform the same function.
  • the lower opening 9 ends with a flange 10 intended to hang the cover 2. If it is deemed necessary, this hanging can be locked by a ring, generally designated by the reference 4, which it is easy to place or removing what simplifies assembly and disassembly and facilitates maintenance.
  • the ring 4 is made of sufficiently rigid material to fulfill its function, it has in its lower part, an inner rim 14 to facilitate its placement and in its upper part, an outer rim 13 to keep it in place.
  • the seal will be crushed from top to bottom by a counter-cover designated as a whole by the reference 5, which will act only by its own weight, its weight must therefore be sufficient to ensure the desired seal.
  • the shape of said counter-cover is designed so that the pressure on the seal and the crushing thereof is uniform over its entire circumference. It is also preferable that it never touches the parts 1, 2 and 4. At least one opening 6 is provided to avoid compression of the air between the counter-cover 5 and the parts 2 and 3.
  • the tank 1, the cover 2, the seal 3, the ring 4 and the counter-cover 5 are assumed to rotate around a common axis shown in phantom in the drawing.
  • the openings 8 and 9 will therefore move away from each other, the pressure of the round 7 on the wall 16 will decrease until allowing the part of the round 7 in contact with the wall 16 to slide easily on said wall.
  • the seal 3 will return to its initial position.
  • the tank 1 will be practically empty when the bottoms 17 and 18 will touch even if the opening 15 is placed a little higher, without however being in relation to the bottom at a height greater than the height of the cover 2, which will allow, if the contents of the tank have made a deposit, to decant without stirring this deposit and to obtain thus a maximum result.
  • the counter-cover 5 can be replaced by any arrangement which ensures uniform pressure distribution over the seal and which has sufficient weight.
