Definitions

  • a plastic tear-0E bottle closure or cap comprising an upper and a lower portion, wherein the lower portion is equipped with a tear-off tongue and may be separated from the upper part by a weakening groove which may be torn open by means of pulling the tear-off tongue, whereby the said lower and upper portions may be separated for first opening the bottle and the upper part may be subsequently reused for closing the same; the invention also comprises a bottle neck adapted to receive such bottle closing cap.
  • the invention relates to a tear-off safety closure of synthetic resin for bottles and to a bottle neck adapted to receive such closure. More particularly, the invention is suitable for crown cap bottles, having an annular bead on the bottle neck for receiving the crown cap.
  • the crown cap has the advantage of safeguarding the user against manipulation of the contents of the bottle by third parties.
  • the fitting of a sheet metal crown cap requires special closing machines for carrying out the mechanical deformation of the rim of the crown cap to ensure that the same is seated reliably on the top bead of the bottle neck.
  • the crown cap Prior to use, the crown cap must be removed with a special tool, the manipulation of which requires a certain amount of force and dexterity.
  • closures for such bottles made of synthetic resins, by means of which the bottle can be closed again, after part of its contents has been used and after the metal crown cap has been removed.
  • closures or caps from a gas-tight closure.
  • the said plastic closures have a projecting gripping rim along their edge, by means of which the closure or cap can be pulled off the bottle neck under elastic deformation.
  • bracket-like tongue on the edge, which ends in a circular eyelet which is pushed over the supporting bead of the bottle neck so that the cap can be reliably secured to the bottle and cannot be lost.
  • the present invention has the object of providing a tearoif safety closure of plastic for crown cap bottles, where by the use of hitherto required crown caps becomes unnecessary, while still protecting the user with regard to the contents of the bottle so that the user has the guarantee that the content of the bottle has not been interfered with.
  • this object is realized in that the bottle neck has, just underneath the edge bead, an annular projecting flange, at the top of which is an annular groove, recessed in the wall of the bottle neck, and in that the safety closure consists of a cap, made in one piece, resting both behind the edge bead and the annular groove in the bottle neck and sealingly on the opening of the neck of the bottle; the cap has, below its upper inner bead, a sleeve-shaped portion, equipped with a tearofl tongue projecting from its lower edge and connected to a weakening groove extending over the sleeve-shaped part of the cap.
  • the diameter of the annular groove and the inner diameter of the internal head on the lower part of the cap are at least equal and preferably larger than the outer diameter of the edge bead of the bottle neck.
  • the weakening groove in the sleeve-like part of the cap extends obliquely to the axis of the cap and terminates below the upper cap portion, engaging behind the edge bead of the bottle neck, whilst the sleeve-like part of the cap passes, under formation of a circular, projecting shoulder into a zone of reinforced or thicker material of the upper part of the cap. It is here essential that a notch should be located at the start of the said weakening groove of the sleeve-like cap portion. The arrangement of this notch is essential, because, for reasons of extrusion techniques, the wall thickness of the weakening groove must not drop below a certain value.
  • the closure When the tear-off tongue is not operated, the closure is firmly connected with the bottle neck. by means of the simultaneous engagement of its edge bead and annular groove with the bottle neck. Removal of the closure without operating the tear-off tongue is impossible, since the lower cap portion engages with its internal bead in the annular groove and rests at the same time with its lower surface on the annular flange of the bottle neck so that opening of the bottle without actually tearing open the tongue is impossible.
  • the lower surface of the annular projecting flange serves to position the bottle in the closure-mounting machine.
  • the annular flange prevents any deformation of the part of the bottle above the flange, and assures therefore the reliable fitting of the closure to the bottle.
  • the cap portion has an annular cylindrical projection overlying the bottle flange, forming with a part of its wall a tear-off tongue terminating in a radially projecting gripping member, and having a weakening groove starting from the weakening groove of the cap portion and extending horizontally below the bead of the cap portion to the gripping member, and terminating in a slot at the side of the gripping member.
  • This modification has the advantage of avoiding a vertically downwardly directed tear-off tongue which can form an obstruction when the closure is fitted by machines, as known in the art.
  • the tear-off tongue is formed by a part of the periphery of a cylindrical portion, extending in a horizontal plane, so that there is no freely projecting tear-ofl member.
  • This closure can also be easily operated, because, owing to the provision of the slot in the said cylindrical portion, the tongue can be easily lifted and pulled off along the weakening groove.
  • the weakening groove has a uniform, small thickness also in the lower part of the inner bead of the cap, where it is either correspondingly deeper, or where the bead has a corresponding break.
  • the wall of the sleeve-like part of the cap is bulging outwardly.
  • the bulge may be straightened by overlying clamps of the closing machine so that, after the removal of the clamps, the inner bead of the lower part of the cap rests firmly in the annular groove and against the annular flange.
  • the height of the lower part of the cap must be correspondingly dimensioned.
  • the upper part of the cap must have on its edge a gripping member, projecting horizontally, and known per se.
  • the closure offers prior to its removal the guarantee that the original charge of the bottle is still within the same.
  • the upper portion can be used again as closing cap and may comprise a known ring member for being mounted on the supporting flange of the neck of the bottle.
  • FIG. 1 is a cross-section of the bottle closure accord ing to the invention
  • FIG. 2 is a top view of the closure of FIG. 1;
  • FIG. 3 is a side elevation of FIG. 1 with tear-01f tongue
  • FIG. 4 is a partial cross-section of FIG. 3;
  • FIG. 5 is a horizontal cross-section of FIG. 3;
  • FIG. 6 shows a modification of the invention in crosssection
  • FIG. 7 is a side elevation of the modification according to FIG. 6.
  • FIG. 8 shows the arrangement of FIG. 7 after rotation through 90".
  • the safety closure according to the invention consists of an integral cap, comprising an upper portion 1 and an apron like lower portion 2.
  • the upper portion 1 of the cap has an upper internal bead 3 which overlies the edge flange 11 of the neck 12 of a bottle, while the lower portion 2 of the cap, having the form of a bulging sleeve with smaller wall thickness, has a lower internal bead 4 along its lower edge, which engages in an annular groove 14 of the bottle neck 12.
  • the closure according to the invention has two closing positions, namely the inner head 3 of the upper cap portion 1 and the inner bead 4 of the lower cap portion 2.
  • the tear-off tongue or flap 5 is pulled upwardly, as shown in FIG. 3.
  • the notch or recess 15 located at the start of the weakening groove 6 in the lower part of the cap, is torn, while strengthening strips 7 arranged on both sides of the weakening groove confine the tearing action to the groove.
  • a notched or recessed line 8 which borders the stronger zone 9 of the upper part of the cap.
  • the cap portion 2 has, adjacent to its inner head 4, a cylindrical extension or apron 16 which overhangs the flange 13 of the neck of the bottle.
  • a part 17 of the periphery of this projection 16 forms the tear-off tongue, wherein the gripping end of the tear-off tongue is equipped with a gripping member or flap 18, projecting radially.
  • the height of this gripping flap 18 corresponds substantially to the height of the projection 16.
  • the gripping flap 18 In the part 16, there is a slot, located on one side of the gripping flap 18. This slot 20 corresponds in height to the gripping member and extends around the same.
  • the gripping flap 18 When the bottle closure is to be opened, the gripping flap 18 can be lifted ofi the bottle flange 13, owing to the provision of the slot 20', and the opening is effected by pulling open the weakening groove 19 and then the weakening groove 6.
  • a safety closure for a bottle having a neck terminating in a mouth formed with a circumferential edge bead, an upper annular recess immediately below said bead, a lower annular recess spaced below said upper annular recess, an annular outwardly projecting flange just below just below said lower recess, said safety closure comprising a synthetic-resin crown cap engaging said bead and closing said mouth of said bottle while defining an upper portion of the closure, said upper portion having a first annular internal bead releasably received in said upper recess, a sleeve-shaped apron formed unitarily with said upper portion and extending downwardly therefrom along the bottle neck between said recesses while defining a lower portion of the closure, said lower portion being provided with a second annular internal bead received in said lower recess, means including a weakening groove extending upwardly along said apron and defining along said apron a tear strip effective, upon its removal,
  • a safety closure for a bottle having a neck terminating in a mouth formed with a circumferential edge bead, an upper annular recess immediately below said bead, a lower annular recess spaced below said upper annular recess, an annular outwardly projecting flange just below said lower recess, said safety closure comprising a synthetic-resin crown cap engaging said bead and closing said mouth of said bottle while defining an upper portion of the closure, said upper portion having a first annular internal bead releasably received in said upper recess, a sleeve-shaped apron formed unitarily with said upper portion and extending downwardly therefrom along the bottle neck between said recesses while defining a lower portion of the closure, said lower portion being provided with a second annular internal bead received in said lower recess and resting against an upper surface of said flange, means including a weakening groove extending upwardly along said apron and defining along said apron
