Definitions

  • the present invention relates to a threaded cap provided with a sealing ring.
  • Caps of this type are already commercially available. They comprise a cylindrical cup that is internally threaded in order to be screwed on the top of the container (bottle). A ring is coupled to the rim of the cup by means of breakable bridges and is internally provided with engagement elements constituted by teeth or flaps which, when the cap is applied so as to close the container, engage below a collar of the container. By unscrewing the cap, the teeth abut against the collar and retain the ring, whereas the resulting axial traction force breaks the bridges, allowing to remove the cup.
  • a principal aim of the present invention is to provide a cap capable of substantially obviating the shortcomings of conventional caps.
  • a threaded cap of the type composed of a cylindrical cup provided with an internal thread and with a sealing ring that is coupled to the edge of the cup by means of a plurality of bridges that form a fracture line and is provided with a plurality of teeth that protrude inwardly from its rim and are directed obliquely towards the cup, characterized in that said teeth are shaped like cylindrical sectors the convexity whereof is directed towards the inside of the cap.
  • the reference numeral 1 generally designates a cap according to the present invention, obtained by molding plastics according to conventional methods.
  • the cap 1 comprises a cylindrical cup 2, inside which a thread 3 is formed.
  • a ring 4 protrudes from the rim of the cylindrical wall of the cup and is connected to said rim by a plurality of bridges 5 that are spaced by slits 6 that form a fracture line.
  • the bridges and the slits can be produced in any manner, for example during the molding of the cap by providing appropriate shapes of the mold or by means of cutting operations performed after molding.
  • a plurality of teeth 7 having the purpose of retaining the cap on the container.
  • Said teeth are constituted by cylindrical sectors having a substantially trapezoid-like shape and the convexity whereof is directed towards the inside of the ring.
  • the teeth are joined to the free rim of the ring 4 by means of the side 8 that corresponds to the shorter base of the trapezoid; said teeth instead rest on the inner face of the ring 4 by means of the sides 9 and 10 that correspond to the legs of the trapezoid.
  • the height of the teeth 7 is such that their upper side 11 lies directly below the line of the slits 6.
  • the cylindrical sector-like shape causes the teeth 7 to have a certain flexibility, in that they can flatten against the wall of the ring 4 when they are stressed radially, and a high flexural strength when they are subjected to loads applied edgeways.
  • the teeth 7, by flattening against the inner face of the ring, can easily slide on the collar 13 that retains the container 12 until, after passing beyond it, by virtue of the elasticity of the plastic material, they regain their stable shape to engage below the collar 13 by means of the rim 11.
  • Figures 3, 4, 6, and 9 illustrate an embodiment in which the teeth 7 are connected to each other by thinner intermediate sectors 14 connected to the lower rim of the ring 4.
  • Figure 10 is a view of a different embodiment that can be applied to the caps of the above-described figures, which consists of a rib 15 protruding inwardly from the lower rim of the ring 4 below the lower side 8 of the teeth. A similar solution is shown in figure 11, where furthermore the rib 16 forms a sort of support for the lower side of the teeth 7.
  • the rib 15 or 16 strengthens the region where the teeth 7 couple to the ring 4. Moreover, the rib 15 or 16 facilitates the folding of the teeth in the position inside the cup after extraction of the cap from the mold.
