Definitions

  • the invention relates to a hermetic closing device for drinking glasses or in general containers for foodstuffs, which device is removable and detachable to permit the application of a cover, of known type, and the hermetic closing of the container and, after the product has been finished, to permit a wider and easier use of the container as a recipient for different applications.
  • Food products which must be conserved hermetically such as for example jams, honey, products contained in oil or vinegar, preserved foods, etc, are usually sold in glass or similar containers, having their upper end shaped to offer a thread, or a partial thread, or similar, onto which a metallic top is screwed or twisted, said top generally being equipped with a gasket to effect a hermetic sealing of the container.
  • Ways of using these containers after the product has been finished is evidently limited to uses which are similar to the original ones, that is, as containers with closing caps.
  • a different use, for example as a drinking glass or cup or similar, is conditioned and limited, both aesthetically and practically, by the said shaping of the upper end; for this reason a large percentage of the containers, and their relative caps, are thrown away when empty since are redundant to what is needed for preserves and similar uses in the normal household.
  • the aim of the present invention is to realise an adequate hermetic closure of differently-shaped containers, such as glasses, bowls, cups, which containers do not exhibit any special shaping of the upper end for the gripping of a cover, which containers, after the product contained in them has been finished, can be advantageously re-utilised domestically for other uses permitted by the conformation of the said containers.
  • the invention relates therefore to a removable hermetic closure device consisting in an externally threaded ring which is positioned around the container, being slid on from the bottom upwards and forced against a superior edge of the said container when the hermetic cover is screwed on to it.
  • a hermetic closure device for drinking glasses or containers in general for foodstuffs which, from a general point of view, is characterised by the fact that it comprises a ring externally equipped with a thread or partial thread, coaxially and removably inserted from the bottom towards the top, on the body of a container up to a position where it is in contact against a perimetral lip exhibited by the upper end of the substantially cylindrical-developping container: in the said position the said ring will removably couple by screwing with the cover of the container, and by the action of the screwing of the cover the said ring, becoming forced by traction against the said lip, hermetic closure of the container will be achieved.
  • a container 1 which can obviously have various shapes, such as drinking glass shape (as in the figures), bowl shape, cup shape, etc.
  • 2 denotes a perimetral lip of the upper end 10, which perimetral lip 2 develops substantially cylindrically
  • 3 denotes a ring exhibiting externally and in relief a thread, or preferably a partial thread 4.
  • a metal cover 5 of known type is destined to be screwed on to the thread 4 of the ring 3.
  • the ring 3 is preferably made of plastic material, for example polypropylene, phertene, nylon etc.
  • the ring 3 is inserted coaxially from the bottom upwards towards the top of the container 1, up until a position of contact with the said perimetral lip 2: then the metal cover 5 is screwed on and pulls the said ring 3 upwards by traction, causing the forced adherence of the said ring 3 against the upper end 10 of the container 1, thus realising the hermetic closure of the said container 1 as figure 4 shows.
  • the container 1 when it is empty, it is sufficient to remove the metal cover 5 and slide the ring 3 out bottomwards. If so desired, the ring 3 could instead be cut away using a pair of scissors.
  • one or more throats or incisions can be made to invite the fracturing of the ring 3, to simplify its removal from the container 1.
  • the said perimetral lip 2 in the simplest form illustrated in figure 1, is realised by means of a flare 21, substantially conical and directed externally from the upper end 10 of the container 1, thus bringing the said ring 3 into a tight fit coupling.
  • the said perimetral lip 2 is realised by means of a perimetral projection 22 against which the said ring 3 strikes (figure 4).
  • the upper end 10 of the container 1 in proximity to the said perimetral projection 22, can be further conically flared outwardly and thus constrain the said ring 3 also by means of a tight fit coupling (figure 4).
  • a sealing gasket 7 (figure 4) can be inserted to obtain a better hermetic closure.
  • the said upper end 10 of the container 1 and the internal surface of the said ring 3 are equipped with reliefs and respective housings 8 preventing the rotation of the ring 3 on the body of the container 1 during the screwing or unscrewing phases of the said metal cover 5 (figure 6).
