Definitions

  • the base ring is connected to a thin-walled bellows which may be pushed inwardly and outwardly through the base ring and has a perforated upper part carrying an outlet tube or a housing for a rotatable cap plug.
  • a rigid protective and sealing cap of plastic material is provided and has a radial peripheral edge so connected to the base ring that when the bellows is pushed inwards, after the base ring has been elastically pushed into or onto the beaded edge of the mouth, it releasably grips the cap. The release is effected by means of a portion of the upper part of the cap which may be pulled or cut off.
  • the present invention relates to a closure member made from plastic material for the mouth or outlet of a container for liquid, said closure member comprising a base ring which may be pressed into or onto the mouth from above and which grips around the edge thereof; a thin-walled bellows is attached to the base ring and able to be pushed therethrough in an inward or outward direction and has a perforated upper portion carrying an outlet tube or the housing of a rotatable plug.
  • the invention consists in that, in a plastic (synthetic resin) closure of the type described above, there is provided a rigid protective and sealing cap of plastic (synthetic resin) material, the radial peripheral edge of which is so connected to the base ring that when the bellows and outlet tube are pushed inwards, the base 3,502,246 Patented Mar. 24, 1970 ice ring having been elastically pushed into or onto the beaded edge of the outlet in the cover, it grips the cap so as to be nonreleasable; the cap may be made elastically flexible in order to be releasable by means of parts on the upper surface of the cap which may be torn or cut off.
  • the upper side of the plastic closure with the bellows and outlet tube, which have been pushed inwardly to seal the outlet aperture in the cover, is closed so that the parts which are pushed into the container remain permanently clean even when the container is stored for a considerable period, and at the same time enables the closure to be sealed in a very simple manner, since once the rigid cap has been pushed into .or over the beaded edge of the outlet in the cover, it is tensioned or clamped so as not to be removable and thus also prevents the whole closure from being removed.
  • the cap may only be removed when a part on the upper surface of said cap is removed, thus rendering it elastically flexible and able to be withdrawn from the closure so that it is possible for the bellows and tube to be gripped and pulled outwards and the tube to be used in order to remove liquid from the container.
  • FIGURE 1 shows a half sectional and half elevational view of a plastic closure according to the invention when the bellows and outlet tube are pulled outwards.
  • FIGURE 2 shows a vertical section through the closure shown in FIGURE 1 with the bellows and tube pushed inwards and with the protective and sealing cap of the invention after insertion in the outlet aperture in the cover of a container,
  • FIGURE 3 shows a plan view of the cap shown in FIG- URE 2, part of the cap being broken away,
  • FIGURE 4 shows a part-sectional view through a modified base ring for the closure with the cap in the position shown in FIGURE 2,
  • FIGURE 5 shows a plan view of the protective and sealing cap
  • FIGURE 6 shows a section along the line VIVI in FIGURE 5
  • FIGURE 7 shows a section along the line VIIVII in FIGURE 5, and
  • FIGURES 8 and 9 respectively show two modifications in sectional and side view having base rings as shown in FIGURES 2 and 4.
  • a plastic closure comprises a base ring 1, to the inside of which is connected a thin-walled bellows or web 2 which forms a unit (i.e. is a single piece) with the base ring 1, and on the perforated upper central portion of which is mounted a housing 3 which also forms a coherent unit (i.e. single piece) with the base ring 1 and the bellows.
  • the cap housing 3 is preferably oriented horizontally and is of conventional tapered form.
  • the cap housing 3 receives a plug 4 which is provided with a radial inlet 5 and an axial outlet 6 and which is provided opposite the outlet with a handle 7 which carries, in axial alignment with the inlet aperture 5, a lug 8 parallel to the axis, the lug projecting over the outer edge of the cap housing 3.
  • the base ring 1 is provided on its outer periphery with two shoulders 9 and 10, the upper shoulder 9 being turned downwards, so that between this downwardly drawn portion and the lower shoulder 10 there is formed an annular groove 11 (FIG. 1).
  • the mouth of the container which is shown diagrammatically in FIGURE 2 at 12, must be beaded outwardly and upwardly at its outlet hole, this beading 13 being upwardly divergent.
  • the base ring of such a closure may be pressed into the container mouth by mechanical means with for example, the lower shoulder enclosing the lower edge of the beading and the downwardly drawn part of the shoulder 9 enclosing the outside of the beading.
  • the base ring 1 is provided, on the inside above its junction with the bellows, with an inwardly open groove 14 into which may be pressed the radial outer peripheral edge of a rigid plastic cap 16, after the bellows 2 and the cap 3 and 4 have been pressed inwards through the base ring and before the base ring has been pressed into the container mouth.
  • This cap which will be described in detail below, fits with its peripheral edge right into the annular groove 14 in the base ring 1, and may be pretensioned therein.
  • the beaded edge 13 acts through the base ring 1 on the rigid cap 16 exerting a radially directed force which is so strong as to prevent the base ring from being drawn out of the container mouth even by force, or from being replaced therein.
  • the cap 16 thus constitutes a protection for the closure portions which have been pressed into the container, i.e. for the bellows 2 and the outlet cap 3 and 4, and at the same time constitutes a seal which renders impossible an authorized removal of liquid from the container.
  • the upper part of the container mouth 12 is outwardly beaded or flanged as shown at 17.
  • the base-ring annulus 1a is then stepped above its junction with the bellows 2 and the peripheral edge 15 of the rigid plastic cap 16 is then applied, possibly with a certain amount of pretension of the base ring 1a, against the steps thus formed.
  • the rigid cap may also be clamped, by means of a thinner peripheral wall, between the upper surface of the base ring and a metal ring or sheath 18.
  • the base ring 1a and the metal ring 18 are then placed over the outwardly extending beaded portion 17 of the container mouth and the metal ring is then pressed together with the base ring inwards against the beaded edge as shown in FIGURE 4, using a tool.
  • the metal ring also grips over (overhangs) the peripheral edge of the rigid cap 16 and thus holds the base ring 1a firmly and nonreleasably against the beaded edge 17 of the container mouth and the compressed deformation of the metal ring clamps the rigid cap 15, 16 over the base ring, so that here, too, the rigid cap 16 forms a protection for the inwardly thrust bellows and outlet tube or spout and in effect constitutes a seal for the closure.
  • the rigid protective and sealing cap 16 which is engaged peripherally around the edge 15 (i.e. the radial peripheral flange which lies in a plane parallel to the rim or bead of the container mouth), preferably has a rectangular inner chamber 19 which receives the upper portion of the pushed-in cap, the top 20 of the cap 16 being provided at one side with a tear-off tab 21.
  • the side wall of the cap is weakened, i.e. thinned, at 22 and score lines 23 extend over the surface of the cover from the side edges of the tear-off tab 21, so that when the tab 21 is pulled the portion of the cover enclosed by the score lines 23 may be removed.
  • the chamber 19 in the cap is provided at right angles to the score lines 23 with a hollow projection 24 which receives the lug 8 of the plug handle 7, the projecting portion thus constituting an indication that the outlet of the plug is correctly positioned.
  • the cap housing 4 is, moreover, advantageously provided, on the upper surface shown in FIGURES 1 to 3, with two spaced-apart peripheral lugs 25 which facilitate the gripping of the cap housing to enable it to be pulled outwards. It is also possible to close the outlet 6 of the plug by means of a plate which may be torn or cut off, thus providing additional security against unauthorized removal of liquid from the container. It is also possible to produce a seal by limiting the degree of rotation of the cap plug when in closure position by means of stop members which must be removed to allow the plugs to be turned into the position in which liquid may be removed from the container.
  • the objects of the invention may also be achieved in a manner different from that shown in FIGURES 1 to 7, and as illustrated in FIGURE 8, as follows.
  • the bead or rim 13 on the container mouth and the base ring 1 with the bellows 2 which may be pushed inward and outward are of the same design as in FIGURE 2.
  • the bellows 2 is provided at the center with a simple outlet tube or spout 26 having external threading onto which may be screwed a rigid cap 16a comprising a cover and an annular wall 27 with internal threading, the arrangement being such that when the cap is screwed on, the upper spout edge is applied in a sealing manner against an annular raised portion 28 on the lower part of the cover.
  • the cap cover is provided with an annular flange 15a which extends freely outwards, the periphery of this flange fitting when the cap is screwed onto the outlet tube 26 into the inner annular groove 14 of the base ring 1.
  • the base ring 1 is pressed into the outlet in the cover, as was described with reference to FIGURES 1 to 3, i.e. the beaded edge 13 of the container mouth exerts, through the base ring 1, a radially directed pressure on the rigid cap 16a which makes it impossible to loosen the closure with the cap without destroying it.
  • the cap thus constitutes a protection for the bellows and outlet tube and also a seal against unauthorized removal of liquid from the container.
  • the annular flange 15a When it is desired to remove liquid from the container, the annular flange 15a is provided with a circular zone of weakened material by reducing its thickness and with a tear-off tab 30 so that when the tab is pulled, a small annular strip is torn out of the flange.
  • the cap 16a is thus released and may be unscrewed from the tube 26 by means of a handle 31.
  • closure with the rigid protective and sealing cap 16a is of the same design as in the embodiment in FIGURE 8, but in this case the cap is clamped in the same manner as described with reference to FIGURE 4.
