Definitions

  • the invention relates to a hermetically-closing cap for containers.
  • the containers referred to are of any shape or dimension, having the inside accessible through a mouth, generally arranged on a superior part of the container.
  • An example of such a type of container is a carafe, used for liquid commestible products, and equipped with a beak for dispensing the contents of the said container.
  • caps for containers of this type generally cylindrical or conical in shape, which realise the closure by exerting pressure against the mouth of the container; some of these caps however either do not give a guarantee of hermetic closure, or are impractical since they require of the operator a certain effort both to achieve closure and especially to open.
  • An aim of the present invention is thus to provide a cap which is of simple construction, which permits collect use for an almost unlimited number of operations, both closing and opening, and which, with the collect dimensions, is usable for containers with whatever shape and size, in particular for a carafe-type container.
  • One advantage of the present invention is that of providing a cap which achieves a hermetic closure and opening of the container with simple and rapid operations.
  • a further advantage of the cap is that of preventing the seal gasket from "sticking" to the cap or the container.
  • a still further advantage of the invention is represented by the fact that the cap is easy to clean, since its component parts are separable among themselves, with simple manual operations.
  • the external element 2 is equipped with an edge 7 which permits the cap to rest on the mouth 6 of the container; it further comprises a truncoconical surface 5 which is connected with a rotation surface that, in particular, is constituted by a cylindrical surface 12. Both of these surfaces are made externally on the external element 2.
  • the external element 2 further comprises an annular striking surface 8 which is made on the inferior part of the external element 2.
  • the internal element 1 comprises an external peripheral thread which, on screwing on to a corresponding internal thread made on the external element 2, constitutes a threaded coupling 3 between elements 1 and 2 allowing them reciprocal rotation and axial movement.
  • the internal element 1 comprises a contrast edge 10, annular in shape, which has a smaller diameter than the diameter of the mouth 6 of the container and which interacts with the elastic gasket 4, forcing the said elastic gasket 4 to move during the relative clockwise-direction rotation between the internal element 1 and the external element 2, along the tract of surface which is more-or-less truncoconical; it further comprises a contrast surface 9 which, following the axial movement between the two elements, strikes against the striking surface 8 made on the internal element 1 and limits the degree of rotation in clockwise direction of the internal element 1 with respect to the external element 2, that is the degree of axial movement of the one with respect to the other.
  • the internal element 1 further comprises a handle 11 activatable from the outside of the cap, which allows the operator easily to turn the internal element 1 with respect to the external element 2.
  • the cap is assembled by screwing the internal element 1 internally to the external element 2, after having disposed the elastic gasket 4 to encircle the cylindrical surface 12.
  • the elastic gasket 4 In this initial position, in which the elastic gasket 4 is kept away from the contrast edge 10, the elastic gasket 4 exhibits an external diameter which is smaller than the container mouth 6 diameter, and an internal diameter which is smaller than the diameter of the said contrast edge 10.
  • the elastic gasket 4 following the clockwise screwing-up of the internal element 1 with respect to the external element 2, is pushed by the contrast edge 10 along the truncoconical surface 5, from the said initial position to a position in which the elastic gasket 4 is compressed between the cap and the mouth 6 of the container; in this position the elastic gasket 4 guarantees the container mouth seal.
  • the elastic gasket 4 spontaneously returns, thanks to its elasticity, into the initial seating constituted by the cylindrical surface 12. In this way, even when there are substances such as sugar present, which might make the elastic gasket 4 sticky, there is never any sticking of the elastic gasket 4 to the container or vice-versa.
