Definitions

  • the present invention relates to an anti-spill device for liquid containers, in particular for dense or viscous liquids, such as engine oil, liquid soap, sauces and the like.
  • the aim of the invention is to eliminate the aforementioned drawbacks, providing an anti-spill device for liquid containers that prevents liquid from escaping during overturning of the container and allows outflow of liquid only following squeezing of the container, preferably when this is in the upturned position, until a pre-set inside pressure is reached.
  • the device according to the invention has the characteristics listed in appended independent claim 1.
  • This device substantially comprises an elastic element, acting as an under-cap that is positioned inside the pouring spout of the container, and provides a liquid seal, withstanding at least the pressure caused by the weight of the liquid held in the container, when this latter is in the overturned position.
  • the container can be handled and overturned, without any risk of causing liquid to escape.
  • Outflow of liquid from the container occurs only when a certain deformation force is applied thereto, so as to raise the internal pressure beyond a pre-set limit, which causes the under-cap to become detached from the spout.
  • the elastic sealing element or under-cap, advantageously has a rod-shaped extension toward the inside of the container, ending in flexible transverse fins, which prevent the under-cap from becoming detached, and therefore dropping during emptying of the container. This can also be useful in the event of partial use of the liquid in the container.
  • the number 1 indicates as a whole a container for liquids, particularly, but not exclusively, dense or viscous liquids such as engine oils or others.
  • the container 1 has a parallelepiped shape, with a side handle 2, and is made, in this case, of flexible composite material, so that it can take on a semi-rigid shape.
  • the invention also applies to commercially available containers made of plastic material and the like.
  • the container 1 in the appended figures has an upper pouring spout 3, tightly closed by a screw cap 4.
  • the spout 3 has a tubular cylindrical shape and is connected to the upper wall 5 of the container 1 by means of a conical wall 6.
  • an anti-spill device for the liquid held in the container 1 is situated inside the spout 3.
  • This anti-spill device indicated as a whole with reference number 10, comprises a cup-shaped element 11, of elastic material such as rubber or the like, acting as an under-cap.
  • the cup-shaped element or under-cap 11 has a stepped upper edge, with a vertical portion 12, adhering to the inner surface 15 of the spout 3, and a horizontal portion 13, that comes to rest on a shoulder 16 made in the vicinity of the free end of the spout 3.
  • the cup-shaped element or under-cap 11 provides a tight closure of the container 1, withstanding a pre-determined internal pressure in the container, this pressure normally being chosen of a certain magnitude higher than the pressure exerted by the liquid when the container 1 is overturned, so that it is possible for the liquid to leave the container, after removal of the outer cap 4, only following squeezing of the outer wall 14 of the container 1.
  • the cup-shaped element 11 has an inner rod-shaped projection 20, which is disposed axially to the container 1 and has radial or transverse fins 22, four in number for example, in the vicinity of its free end 21, their length being greater than the radius of the spout 3, so that during use the under-cap 11 is not completely detached, remaining integral with the container, because of interference of the radial fins 22 with the inner surface of the conical wall 6.
  • a stalk 23 is provided, that acts as the gripping element for the user's fingers for possible removal of the anti-spill device 10 from the container, following elastic yielding of the radial fins 22.
  • the screw cap 4 is removed and the container is tilted or upturned, to place its spout 3 in the opening 30 of the recipient into which the liquid in the container 1 must be poured, for example the engine of a motor vehicle, in the case of engine oil.
  • the cup-shaped element or under-cap 11 remains in place inside the spout 3, preventing any escape of liquid.
  • the under-cap 11 can be repositioned in the spout 3, and the cap 4 screwed on again, for later use, which will take place in the same way just described.
