Definitions

  • the present invention relates to removable closures of elastic material, ⁇ and more particularly to the type of closure which consists of a cap part and a guard ring part interconnected for easy separation by an elongated weakened closure portion.
  • One of the closure parts has an annular bead engaging a peripheral groove in the container mouth and the cap part has a lug which may be grasped for lifting the cap part oftr the container mouth after separation of the cap part from the guard ring along the weakened ⁇ closure portion.
  • the closure is relatively at and barely exceeds the height Iof conventional metal caps so that these plastic closures may be handled and sorted on conventional lclosure sorting machines.
  • FIG. 1 is a side view of one embodiment of the closure of this invention
  • FIG. 2 is a similar view, partly in section, of another embodiment
  • FIG. 3 is a vertical section of still another embodiment
  • FIG. 4 is a view similar to that of FIG. l of a further embodiment of the closure
  • FIG. 5 is a side view, partly in section, of yet another embodiment
  • FIG. 6 is a vertioal ⁇ section of a further embodiment
  • FIG. 7 is :a top view of FIG. 6;
  • FIG. 8 is a partial Vertical sec-tion of another embodiment
  • FIG. 9 is a horizontal section rthrough both closure parts of still a further embodiment.
  • FIG. 1G is a side view of another embodiment.
  • ythe closure -of the invention is designed to be applied originally to the mouth of a container, such as a bottle, to close the container mouth and then t-o be temporarily opened and closed during the use of the contents of the container.
  • the container mouth denes a periphenal groove and the closure has a cap part anda guard ring part.
  • At least one of the closure parts is secured to the mouth by an annular bead engaging the peripheral groove at its deepest recess when the closure lCC is originally applied to the container mouth.
  • the cap part has a lug which may be gra-sped for lifting the cap part of the container mouth and thus gaining access to the interior of the container.
  • a weakened portion interconnects the two closure parts for easy separation.
  • the closure parts may be made of any suitable natural or rsynthetic elastomer material :having the required elastic properties.
  • Useful materials include such synthetic resins as polyolens, for instance, polypropylene and polyethylene, poly'formaldehyde, polymer blends and copolymers thereof, natu-ral rubber, butyl rubber, and other vulcanized materia-ls, silicone rubber, and like hfardenable elastomer materials generally used for closures of the present type.
  • the two-part closure is shown to Icomprise a fixed part 12 land a movable cap part 11 which are interconnected by weakened portion 13 produced by cutting out a portion of the closure material lbetween Ithe two parts.
  • the cap part 11 has a lug 14 by which the cap may be grasped and opened.
  • the weakened portion is weakest at 13a adjacent the lug, where more material is cut away and where, if desired, all material may be removed t-o produce a slot, thus facilitating removal of the cap from the iixed closure portion when the crap is pulled by lug 14.
  • this weakest portion or slot extends laterally beyond the lug and, if desired, this extension may be unilateral ⁇ so as t-o obtain the most favorable tear langle for the removal of the cap.
  • the remainder of the weakened interconnection will be torn 'and the entire cap will be separated from the iixed ring if the weakened portion is annular. If it does not cover the entire periphery, only a portion of the cap will be removed from the ring.
  • the cap part forms a spheroidal membrane which may readily yield to distortion due t-o increased pressure emanating from the interior of the container, due to increased temperature, for instance, without moving the rim portions of the closure engaging the container mouth, which could force the closure off the mouth.
  • the curved central membrane of the :cap prevents undesirable deformation of the closure portions which engage the container mouth and hold it on the mouth.
  • FIG. 2 The embodiment of FIG. 2 is generally similar to that of FIG. l and like reference numerals in this and all other figures designate like parts which, therefore, do not require repeated description.
  • the closure is seen mounted on a container mouth 1 which deiines a peripheral groove 2, the deepest recess of which is engaged by the annular bead 12 of the guard ring 12a of the closure.
  • the cap 11a also is shown to have a bead 11 engaging the groove 2, a wedge-shaped cut in the beaded portion of the two closure parts providing the weakened interconnecting portion therebetween.
  • the opening lug for the cap is constituted by a downwardly extending flap 19 arranged in a cut-out portion of the ring 12a.
  • the cutout portion is produced cutting the end portions 13e, 13e -between the cap and ring downwardly to the lower end of the ring.
  • the cap remains hinged to the ring.
  • FIGS. l and 2 are alike and, as shown in FIG. l, a peripheral rib 18 may project from the ring part, which serves to reinforce the closure.
  • the closure carries a stopper 26 which extends into the container mouth 1a and has an annular flange 28 inserted into an annular groove 29 in the cap part of the closure.
  • the stopper 26 includes a bottom 27 of curvilinear crosssection. The stopper 26 will reduce any gas diffusion from the interior of the container through the closure and will prevent it practically completely if the stopper is made of an impermeable material.
  • FIG. 4 The embodiment -of FIG. 4 is similar to that of FIG. 1 but the guard ring part 12 of the closure has xed thereto a tongue 34 in juxtaposition to lug 14 lof the cap part 11.
  • This tongue constitutes a tear strip and incisions 35, 35a, 35b make it possible to grasp the strip by rst tearing along the incisions and then to tear the ring part off the container mouth along the weakened portion 13.
  • the cap 11 may then lbe readily removed from the container mouth by pulling on lug 14 and thus disengaging the bead 11 of the cap from the groove of the container mouth.
  • the weakened portion is formed by an obliquely inclined incision 13d extending down to the lower edge of the ring part of the closure.
  • the tear strip "34 is arranged below the opening lug 14a and when the closure is to be opened, the tear strip is pulled along incision 13d and the lug 14a is pulled up. Alternatively, the lug may be pulled up without pulling on the tear strip 34, thus tearing the cap along incision 13d.
  • the lug 14a has a series of gripping grooves 14h on its underside for engagement with a bottle opener which may be used to open the closure by exerting an upward lever action on the lug.
  • the oblique inclination of incision 13d has the advantage of causing -a relatively small weakening of the ring bead, which would be caused, for instance, by a perpendicularly extending incision and thus makes this embodiment particularly useful for the closure of bottles, the contents of which produce a uid pressure against their closure.
  • the closure is mounted on a container mouth 1c with an undercut opening 3 engaged by a conforming ange 24 integral with the cap part 11b and extending into the undercut opening. It is advantageous to provide such a cap with an annular reinforcing rib 36 gener-ally in alignment with the annular ange 24.
  • downward pressure on the reinforcing rib 36 will depress the annular ange 24 whereupon the flange will snap back with a pre-stress against the upper edge of the container mouth when the pressure on the reinforcing rib is released.
  • the annular beaded portion 11 of the cap part of the closure engages the peripheral groove of the container mouth and is surrounded by the guard ring part 12b of the closure.
  • the weakened closure portion interconnecting the two closure parts is very weak, being formed by a deep vertical incision 13e between the beaded portion 11 of the cap and the upper rim of ring 12b adjacent the beaded cap portion.
  • the guard ring 12b is connected to the opening lug 14e of the cap 'by a weakened portion 131 produced by tangentially extending incisions conforming to the configuration of the lug.
  • FIG. 8 A modification of the incision forming the weakened interconnecting portion of the closure of FIGS. 6 and 7 is illustrated in FIG. 8 wherein the lower incision penetrates only about half way into the closure material and an upper incision 13g is made into the material to produce a centrally extending weakened annular portion between the guard ring 12b and the beaded portion 11 of the cap part of the closure.
  • the opening lug 14d which is integral with the cap part of the closure, does not project beyond the ring closure part 12b but conforms to its periphery so that the entire closure is circular.
  • Incisions 13e and 13f are similar to those shown in FIG. 7 so that the lug may be readily separated from the guard ring 12b and the cap torn off the ring along the annular weakened portion interconnecting the cap and the ring. Separation of the two closure parts is facilitated by providing a short fully broken section 39 in the weakened connecting portion, this broken section being positioned diametrically opposite the lug 14d in the illustrated embodiment.
  • the weakened connecting portion between the two closure parts may extend adjacent the entire periphery of the two-parts so that the two will be fully separated when pulled apart. However, it is also possible to leave a short section along the periphery of the closure, for instance, at the opening lug, without weakening whereby a loop Will remain which may be used, for instance, to place the cap on the container mouth and thus have it ready for re-closure.
  • the closure embodiments of FIGS. 6 to 9 are relatively flat, i.e. the ratio of the closure diameter to its height is at least about 3:1.
  • the guard ring of the closure By mounting the guard ring of the closure about the annular beaded closure portion engaging the container mouth groove, the elastic pressure of the beaded closure portion against the container mouth is considerably enhanced when the closure is originally applied to the mouth and before the guard ring is removed during actual use of the container. This, of course, increases the effectiveness of the closure.
  • the flat configuration of the entire closure and its rib-like rim constituted by the guard ring produces a simplified closure configuration, which is easy to manufacture and also makes it possible to sort the closures before use in known sorting machines.
  • the weakened connecting portion between the two closure parts is not subjected to any uid pressure from the contents of the container and may, therefore, be made particularly thin and weak, to facilitate the separation of the guard ring from the closure.
  • the closure embodiment illustrated in FIG. 10 is like that of FIG. 1 or 3 but the incisions 13h, 131', and 13j are so designed that lifting of the cap part 11 by lug 14 first causes separation of the closure parts along lines 13h and 131', a reinforcement at 40 then guiding the separation along line 13j down to the non-weakened small section 41. Only when this latter section is forcefully split will the guard ring be fully separated from the cap part so that the cap part may be removed from the container mouth.
  • the oblique incision 13j is spaced from the opening lug 14 by about 160.
  • All of the closures described and illustrated hereinabove may be readily opened without tools and may be closed again while being safe against tampering as long as the guard ring remains attached to the removable cap part of the closure.
  • the cap part can be opened only after the guard ring has been separated from the cap part along the weakened portion interconnecting the same.
  • a characteristic feature, especially of the closure design of FIGS. 1 to 5 and 10 is the feature that the beaded guard ring is arranged so high that it engages, in its original state, the deepest recess of the peripheral groove in the container mouth.
  • the weakened closure portion between the guard ring and the cap part i.e. the part which, after separating both parts and re ⁇ moval from the container mouth, may be replaced on said container mouth to again close the container
  • the weakened closure portion between the guard ring and the cap part i.e. the part which, after separating both parts and re ⁇ moval from the container mouth, may be replaced on said container mouth to again close the container
  • Both beaded parts together firmly press the closure on the container mouth and thus achieve satisfactory, pressure-resistant sealing of the, container.
  • the partly or completely removed cap part is still provided with a small and readily yielding beaded part which permits easy closing and opening of the container by hand.
  • the novel features of the present invention are not only that the entire bead of the closure is divided in two parts by an incision but also that the entire bead of the closure and thus the guard ring are designed very compact and sturdy.
  • the closure according to the present invention engages only the first peripheral groove of the container mouth which groove is arranged directly at the mouth, and not any subjacent groove.
  • the closure according to the present invention represents in fact a so-called crown bottle cap.
  • lug 14 may be arranged below weakened portion 13, i.e. between the end portions 13C, 13C of FIG. 2.
  • a narrow tongue 34 may be provided below lug 14 which yields, on tearing, a slot passing above lug 14. As a result thereof cap 11 can readily be removed by pressing upon lug 14.
  • the beaded part 11 may be thickened and thus strengthened at the place above tongue 34.
  • closures according to the present invention can be provided with a gasand aromatight coating, for instance, by immersion.
  • the stopper 27 inside the closure may be provided with a rubberelastic filler to achieve gasand aroma-tightness.
  • the central portion 16 of the cap part 17 may be separated from the cap part not only by groove 17 provided at the outside of the cap but by a groove provided at the inside of the cap or by two or more grooves to yield the membrane-like central portion 16.
  • Stopper 26 may consist of a material different from that of the closure itself.
  • the incision 13d may not only be obliquely inclined in a straight line but may also have a wavelike form.
  • a container closure of elastic material having an internal plug stopper portion for a container having a mouth with a peripheral groove adjacent said mouth comprising (a) an initially sealable, removable and later reuseable cap part,
  • annular bead on the inner wall of said peripheral part and extending into said cap and guard ring parts, said bead being adapted to sealably engage the deepest recess in a peripheral groove of a container scalable with a crown-cap and said bead dividing when said guard ring is separated from the cap part to leave part of the entire bead of the closure attached to the cap part,
  • an opening lug integral with the periphery of said cap part and adapted so that when the lug is forced away from the container mouth the weakened peripheral part ofthe stopper tears, the guard ring part separates from the cap part, and the cap is removed from the mouth of the container.
