Definitions

  • Plastic caps as hitherto made for bottles and other containers of the type referred to have been constructed with a shirt portion designed to surround the bottle neck and having an inward bead at the lower end thereof to engage behind the cap holdingshoulder of the bottle.
  • the cap To place such a capon a bottle mouth, the cap must undergo a widening sufficientto permit its head to slide past the thickened neck portion tforrning the-shoulder of the bottle.
  • the force at whichthe bead of the cap will engage behind 'the shoulder of the bottle will depend on suchelasticity'as remains in the cap after it'has been widened as described. This-engagement force will in many cases be insufficient.
  • a closure for crown cork bottles and other containers having a cap holding shoulder behind a mouththereof which closurecomprises a cap having a rim-portion consisting of a plurality of mutually spaced rim sectors closable in end to end relationship around the cap holding shoulder of a bottle or other container on which/the cap is placed and constructed with circumferentially engageable interlocking means.
  • the grip of the cap behind the shoulder of the bo-ttledoes not depend on the elasticity of the plastics material but on positive interlocking.
  • the cap can beimade in thesame outer shape as .theordinary metal caps and like these-is applied to a bottle by the combination-of. an axial force exerted onthe bottom of the cap and a radial contractingforce exerted ona rim portion of the cap. It: can therefore be applied by means of theordinary-bottling machines without any change. Likewise. it canwbe.
  • FIG. 1 shows an axial cross section of the closure as placed on a bottle top, as well as a tool'for so placing the closure, the left hand half illustrating the cap and tool after completionof-theclosing operation, and,-the right hand half, illustrating same before commencement 1 of the closing operation,

  • FIG. 5 a section on an enlarged scale along the broken line VV in FIG. 2, and i FIG. 6 a section on an enlargedscale along the'broken, line VIVI in FIG. 2.
  • the closure cap illustrated in the-drawings is, made from a material of the plastics group and comprises a circular top wall 1, the upper or outer face l of which may bear suitable inscriptions, decorations, or the like;v applied thereon as v by printing,- stamping, or, in other; conventional manner,
  • the cape has. a depending skirt; or rim portionintegral with the top wall 1 and which is" formed by a plurality of rim sectors 3;which 'are; sep; arated by radial incisions 4 opening downwardly through; the lower edge of the skirt, asillustratedin FIGURES- 2, 3 and 4.
  • the relatively circumferentially opposed-or radial end faces 3a and 3b respectively ofadjoining, sectors 3 on opposite sides of each incision, 4' converge upwardly, as is shown detail -'in-F IGU;RE-.4; andthe lower edges or extremities of therespective. sectors are I normally spaced apart across the lower ends,,of- -the,,;in-- cisions 4 in the normal state or condition of the cap as it is originally formed andbefore it is applied to a container, all as is illustratedin theright-handhalfof FIG; URE 2.
  • the adjacent end; faces 3a and ;3b,;respectively of each pair of adjoiningsectors are respectively formed with circumferentially directed snap. fastener.
  • the snap fastener means interconnect the respective rim. sectors S against circumferential separation after application ofthe cap to the container.
  • the snap fastener means are exemplified by alocking tongue or projection siaffixed to and projecting circumferentially from one end face 3a of its associated sector for cooperative locking reception in an oppositely circumferentially directed socket '6. having its mouthopening through the adjoining end face 317.
  • the lockingtongueS includes, anenlargement 5a adjacent its free end, having one or more generally radially disposed locking faces-5b onthe; circumferential side thereof remote fromitsfreeyend, Preferably, also, the enlargement 5a converges toward its free end for wedging reception in the mouthof the cooperating socket 6.
  • the socket 6 in each instance has an entry portion 6x of smaller cross sectional dimension than the locking tongue enlargement 5a.v This entry portion 6x extends circumferentially inwardly from the socket mouth 7 which preferably is arranged to diverge outwardly circumferentially for wedging reception of the.
  • the entry portion 6x opens into an enlarged portion 6a of the "socket spaced inwardly from the socket mouth; and at the juncture of this entry portion and the enlarged portion 6a, the socket is provided with one or more generally radiall disposed locking faces 6b, these locking faces 612 being directed inwardly away from the socket mouth 7 for abutting locking engagement with the respective locking faces 5b of the locking tongue or projection 5.
  • Each sector 3 is formed near its lower extremity with an inwardly projecting flange 30 for locking reception beneath the usual external head of the bottle neck.
  • the inclined or tapering arrangement of the enlargement 5a and the socket mouth 7 facilitates the entry of the tongue into the socket and the necessary expansion of the entry portion 6x due to the wedging action of the enlargement 5a as the latter is forced through said entry portion for reception in the enlarged socket portion 6a.
  • each of the sockets 6 is arranged to open downwardly through the lower edge or extremity of its associated sector;
  • the rear faces of the head portion of the projections 5 are inclined at an angle a to the end faces of the sectors 3.
  • a sleeve portion 8 protrudes from the inner face of the bottom portion 1 and has a wall thickness decreasing in a direction away from said top wall 1.
  • the sleeve portion 8 is designed to be introduced into the bottle mouth, and to facilitate such introduction the outer edge of the free marginal portion of the sleeve 8 is inclined at 9, thereby to facilitate the centering of the closure cap on the bottle neck.
  • the sleeve On its outer face the sleeve is constructed with spaced annular ribs 10 which are disposed at a downward inclination and are sufliciently flexible as to' be urged radially outwardly against the inner wall of the bottle mouth under the influence of a pressure prevailing in the bottle, thereby to secure a good sealing and a firm seating of the cap within wide tolerances as regards the dimensions of the bottle mouth.
  • annular groove 11 is provided on the inner face of the cap.
  • the groove 11 increases the flexibility of the connection between the rim sectors and the top wall thereby facilitating the contraction of the rim sectors around the shoulder of the bottle.
  • annular groove 12 On the inner face of the cap there is also provided an annular groove 12 to receive irregularities of the type which will invariably occur in the zone in question of a bottle mouth as a result of the bottle moulding procedure.
  • the closure is applied to a bottle mouth in the following manner:
  • the described caps which in the original state have the same dimensions as ordinary metal crown cork caps, are sorted and brought into correct position in the chute of the closing machine where they are checked and rejected in case of faults, as usual.
  • the caps assuming the correct position are successively conveyed to the closing tool of the revolving or intermittently operating closing machine.
  • the closing tool which is represented in FIG. '1 by a piston 13 and a centering ring 14, the cap is located with the marginal edges of the sectors 3 in contact with a shoulder 15 of the centering ring 14, as illustrated in the right hand half of FIG. 1. If no bottle is fed forward to the closing tool before it performs its operating stroke, the cap remains in its original shape and is retained in the centering ring to thereby automatically prevent reception therein of another cap.
  • the piston 13 is lowered and presses the cap against the bottle mouth, whereby the sleeve por tion is introduced into the bottle mouth.
  • the centering ring 14 is lowered and urges the sectors 3 from a position at an inclination of about 30 inwards against the bottle neck whereby the projections 5 are introduced into the recesses 6, the latter being momentarily widened to permit such introduction.
  • each rim sector 3 is off-set outwards from the axis of the cap, the centers of curvature of all the sectors being located on a common circle concentric with the cap. Owing to this arrangement the ends of the rim sectors will engage the bottle neck first during the closing operation whereby the interlocking projections and recesses will be guided into correct engagement with one another. Moreover, owing to the described oif-set arrangement of the centers of curvature of the rim sectors it will be easier to tilt the rim sectors out of engagement with one another by means of an ordinary bottle opener. On the other hand, the engagement between the projections and recesses is very firm as long as the rim portion is only subjected to circumferential stresses, such as is the case under the influence of the pressure prevailing in the interior of the bottle.
  • the piston 13 and the centering rim 14 are again moved upwards.
  • the outer flank 18 of the rim sectors is so constructed asstill to be disposed at an inclination in the closed position of the cap.
  • the closed bottle can therefore pass the narrowed zone of the centering ring without difliculty whereby the receiving chamber of the closing tool becomes ready to receive the next cap.
  • the cap may suitably consist of a tough low pressure polyethylene which will secure persistence of the interlocking of the rim sectors even with small dimensions of the projections 5 and recesses 6 and with high bottle pressures up to about 15 atm. and high temperatures up to about C. In spite of the great toughness of the material, tolerances of the bottle neck diameter will be taken up by this material.
  • the rim portion When the bottle is opened by means of an ordinary cap opener, the rim portion will be torn up an previously described by disengagement of the interlocking means of at least two of the rim sectors.
  • the cap may also be constructed with one or more weakened. zones 19 where the wall thickness is so reduced that tear ing will take place there.
  • the cap may also be provided with a tearing-up strip which however should preferably be so constructed that it does not protrude beyond the contour of the cap since otherwise the latter cannot be applied by means of an ordinary bottling machine.
  • the cap When the cap has been removed, it may be applied to the bottle again by hand in order to close the bottle for a relatively short period. Nevertheless it will be directly visible that the cap has been removed.
  • the pressure in the interior of the bottle will urge the ribs 10 into sealing engagement with the inner wall of the bottle mouth and, besides, the inner pressure acting on the bottom portion of the cap will tend to urge the zone of transition between the rim sectors and the bottom portion into sealing engagement with the outer wall of the bottle mouth, viz by tending to straighten and thereby to radially contract the. cap wall in the said zone so that there will in fact be two sealing zones between the interior of the bottle and the. surroundings.
  • the top wall should be rigid and it may therefore: be constructed with a greater wall thickness than thezone.
  • a closure for a container having an external bead encircling its neck below the container mouth comprising a circular top wall, a plurality of rim sectors depending from the outer periphery of said top wall, said sectors being flexibly connected to said top wall for relative flexing in radial planes toward and away from an axis concentric with and perpendicular to said top wall, said top wall and said rim sectors being integrally interconnected parts of a unitary cap structure of flexible plastic material, each pair of circumferentially adjoining sectors having circumferentially opposed end faces disposed for relative movement into substantial endwise abutment when the said sectors are flexed radially inwardly toward said axis, circumferentially directed snap fastener means carried by said adjoining sectors at their said opposed end faces respectively for interlocking engagement with each other incident to such relative movement of the said faces, to secure said sectors against subsequent circumferential separation, said sectors respectively including inwardly projecting flanges adjacent their lower extremities for holding engagement beneath the said external bead of
