Definitions

  • the cap in a cap for enclosing a nozzle or other opening of a container and held in position thereon by an internal circumferential rib on the cap engaging an annular surface such as the underside of a bead around the container opening, the cap comprises a skirt made of a flexible material and having the internal circumferential rib or like projection formed at .its lower edge, and an inverted cupshaped member located within the skirt and slidable axially with respect thereto, the skirt and cup-shaped member being so formed relatively to each other that movement of the cup-shaped member towards the lower end of the skirt expands the said lower end to free the cap for removal, means being provided whereby a visible change in the condition of the cap produced by such movement of the cup-shaped member is such that the said cap cannot be restored to its original appearance.
  • the skirt and the cup-shaped member may be interconnected by connecting means which are interrupted by movement of the cup-shaped member to expand the lower edge of the skirt.
  • the skirt and the cup-shaped member may be formed with interlocking elements which engage one another when the cup-shaped member is moved to expand the lower edge of the skirt and prevent the return of the cup-shaped member to its initial position.
  • the cap may be made in various shapes, according to the container on which it is to be used, and possibly also the ornamental considerations which it is desired to benefit. Most conveniently, from a manufacturing point of view, it is to make the skirt with an internal diameter which decreases towards the end adjacent to the container mouth, atthe same time as the cup-shaped member is made with an approximately constant diameter along its entire axial length.
  • FIGURE 1 is an axial sectional view of one form of cap, the cup-shaped member being shown in different positions on opposite sides of the vertical centre line;
  • FIGURE 2 is a sectional view taken along the line 7 11-11 of FIGURE 1;
  • FIGURE 3 is a part sectional view, corresponding to the left half of FIGURE 1, illustrating a second embodiment
  • FIGURE 4 is an axial sectional view, similar to FIG- URE 1, illustrating a third embodiment of the cap according to the invention.
  • FIGURE 1 of the drawings 1 is a con tainer which, in the usual manner, is provided with a dispensing device 2, such as a spray nozzle for the atomizing of the container contents.
  • the dispensing device is mounted in a closure 3 for the container, and around the closure the container 1 is provided with a bead-like collar 4 having a flat undersurface 5.
  • a cap to cover and protect the dispensing device 2 comprises a skirt 6, which, preferably, is made of a hard but flexible plastic material. At the end adiac'ent the container, the skirt terminates in an inwardly directed circumferential rib or like annular projection 7, which has a flat surface 8 adapted to engage the flat undersurface 5 of the bead-like collar 4 on the container 1.
  • the skirt is substantially cylindrical and terminates, at the end remote from the annular projection 7, in a collar 9, a number of reinforcing ribs 10 being provided in spaced relation around the outer wall of the skirt 6.
  • a member 11 of inverse cup-shape is located within the skirt 6 and has an exterior diameter substantially equal to the interior diameter of the skirt 6, so that the member 11 may slide axially of the skirt.
  • Axially extending grooves 12 are arranged in spaced relation around the exterior surface of the member 11, for the purpose of relieving excessive pressure which may build up inside the cap to the annular space 13 defined between the collar 9 at the top of the skirt and the top portion of the member 11.
  • the free lower edge of the member 11 may have a tapering cross section, produced by an oblique face 14 on the inside and a slightly concave oblique face 15 on the outside, defining a surface essentially complementary to the shape of the projection 7 of the skirt 6.
  • the cup-shaped member 11 is so formed as to be more rigid than the skirt, or the skirt may be provided with slits extending upwardly from its lower edge to reduce its resistance to radial expansion.
  • a foil 16 is shown as being secured in a groove formed in the collar 9 and following the top surface of the member 11 when the cap is in position for storing, as shown to the left in full lines in FIGURE 1.
  • the member 11 is shoWn as being provided with a thin circumferential flange 17, the circumference of which is secured in the collar 9.
  • the central part of the foil 16 may be secured to, or may merely lie against, the closed end surface of the cupshaped member 11.
  • the portion 7 of the skirt is, due to its elasticity, returning to its initial, inwardly directed position, with the result that the cap may again be forced downwardly around the bead 4 and the surface 8 re-engaged with the undersurface 5 of the head.
  • the foil 16 or the flange 17 remains, however, in its broken or torn condition, thereby indicating that the cap has been removed.
  • the foil 16 may, due to an excessive pressure appearing within the cap, for instance caused by aleakage of the contents of the container through the device 2, bulge upwardly and thereby indicate that such leakage is taking place.
  • the foil 16 may, however, be provided with a number of small perforations for the purpose of relieving such pressure.
  • the cup-shaped member 11 may, as described above, be returned to its upper position, so that the cap may be refitted to the container.
  • FIGURE 4 such possibility is prevented, for the purpose of definitely avoiding any fraudulent replacement of the broken or torn connection between the skirt and cup-shaped member.
  • the member 11 is provided with a number of projections 21 arranged in spaced relation along a circumferential line around its outer peripheral surface the skirt 6 being provided with a circumferential groove 22 extending unbroken around the inside of the skirt and adapted to be engaged by the projections 21 in such a manner that the member 11 and the skirt 6 are axially locked relatively to each other.
  • the projections 21 are, as shown, each provided with a fiat top face 23, for the purpose of securing a positive engagement with the oblique top surface of the groove 22, to the effect that a withdrawal of the member 11 is positively prevented.
  • the lower surfaces 25 of the projections 21 are oblique, so that they may slide along the oblique face 26 defining the lower surface of the groove 22, and the cup-shaped member 11 may be pushed downwardly within the skirt 6.
  • the skirt 6 is provided with a small projecting rim 27 forming a step on which the lower edge 28 of the member 11 may rest when the projections 21 are in engagement with the groove 22.
  • the skirt 6 is also, in this embodiment, provided with an additional circumferential groove 32 which may be engaged by the projections 21 on the member 11 when the latter is pushed downwardly to expand the skirt 6 and disengage the surface 8 from the container bead.
  • the member 21 When the member 21 is pushed to this position the lower edge 28 thereof, as shown on the right-hand side of FIGURE 4, abuts against the surface 8 of the internal projection 7 on the skirt.
  • the engagement of the projections 21, in the groove 32 positively prevents a withdrawal of the member 11, and it is not possible to return the projection 8 to a position underneath the container bead. Consequently, when the container is once opened, it is not possible to return it to the condition existing prior to the opening operation.
  • the projections 21 and the grooves 22 and 32 are shown disposed in a plane at right angles to the axis of the cap, to the effect that the member 11 may be inserted into the skirt in an angular position, but obviously any other disposition of the grooves and pro,- jections may be adopted, provided that the plane through the projections coincides with that through either of the grooves in case it is desirable, for any reason, to ensure that the member 11 can only adopt a certain angular position relatively to the skirt.
  • both the skirt 6 and the member 11 is presumed to be essentially cylindrical, but obviously both members may be made more or less frustoconical, having the smaller bases facing upwardly.
  • a cap for enclosing an opening of a container adapted to be held in position thereon by the engagement of an internal circumferential riblikc projection on the cap with an annular surface of a head around the container opening
  • the cap comprises a skirt made of a flexible material and having the internal circumferential riblike projection formed at its lower edge, and an inverted cup-shaped member located within the skirt in axial slidable engagement with the same, the skirt and cup-shaped member being of such relative formation as to cause expansion of the lower end of the skirt by a movement of the cup-shaped member towards the said lower end of the skirt, means being provided adapted to produce a visible change in the condition of the cap by such movement of the cup-shaped member.
  • a cap according to claim 1 wherein the skirt and cup-shaped member are interconnected by connecting means adapted to be interrupted by a relative movement of the cup-shaped member and the skirt for the purpose of expanding the lower edge of the skirt.
  • a cap according to claim 1 wherein the skirt and the cup-shaped member are provided with integral interlocking elements adapted to engage one another by a relative movement of the cup-sha ed member and the skirt for the purpose of expanding the lower edge of the skirt, thereby preventing a return movement of the cupshaped member to its initial position.
  • a cap as claimed in claim 1 wherein the skirt and the cup-shaped member are interconnected by connecting means adapted to be interrupted by a relative movement of the'cup-shaped member and the skirt for the purpose of expanding the lower edge of the skirt and arranged along the circumference of the closed top surface of the cup-shaped member, the connecting means comprising a foil-like member, the external circumference of which is secured to the skirt and the central portion of which is engaging the closed top surface of the cup-shaped member.
