Definitions

  • the invention relates to a closure for tightly closing and yet easily reopening a bottle or the like.
  • the bottle has a neck with a dispensing opening, a neck face surrounding it and a muzzle bead located below the latter and delimited on its underside by a constriction, the closure a cap serving as a closure head with a roof wall and around this circumferential cap side wall with slits extending transversely to the latter from the bottom edge thereof for spreading when placed on the dispensing opening of the bottle and with inwardly protruding slots on the inside of the cap side wall in the closed position for engaging the constricted underside of the muzzle bulge of the flat serving inner ring bead, a spout attached to the inside of the roof wall and serving in the closed position for sealing the dispensing opening of the bottle, one operable on an actuating side of the cap with the finger e actuating nose, as well as each slot in the cap side wall in the closed position in the ring position, sealingly pressing the inner
  • this closure which is stiffer due to the manufacturing process, does not withstand much more internal pressure than a closure made of less elastic material and produced with less compression.
  • the temperature In order to pasteurize the bottle contents, the temperature must be raised to at least 62 ° C for at least 20 minutes.
  • the well-known closure can withstand temperatures of approx. 56 ° C without softening.
  • the new closure must therefore be made of harder material and is therefore even more difficult to put on and take off.
  • the object of the present invention is therefore to improve the closure described above in such a way that it withstands pasteurization conditions without leaking or being blown off, and at the same time is at least as easy to put on and take off as the closure, which is made of a more elastic material.
  • closure of the type described at the outset which is characterized in that the tension bridge member of at least one slot can be torn open at least on one side of the latter when the closure is first opened up to the slot bridged by it is, so that when the closing position is taken up again, the tangential extension and thus the contraction of the slot in question is canceled when the tension bridge member is torn open.
  • the tear-open tension bridge member can also have webs which can be torn open on both sides of the slot bridged by it, with which it is connected to the side wall of the cap instead of only on one side.
  • This slot spreads unhindered by a tangential tension.
  • the tearing open of the web of a tension bridge element and thus the loss of tangential tension via the slot when the closure is attached also means that the fact that the bottle has already been opened after the original filling has been made clear.
  • the not yet opened tension bridge link thus also serves as a guarantee seal.
  • the slit of the cap side wall can consist of at least two slits, which over the opposite areas between the actuation side and the opposite side of the Cap side wall are distributed in the same way, and a clamping bridge member can be provided per slot.
  • the tension bridge member bridging the slot is arc-shaped and, when the slot is expanded, is elastically resiliently stretchable and articulated on both sides of the slot bridged by it at a short distance from the latter to the side wall of the cap, and each of the two tension bridge members can be on at least one side of the slot bridged by it possess the above-mentioned web which can be torn open in the tangential direction and via which it is connected to the side wall of the cap.
  • the actuating lug provided on the actuating side can be integrally and rigidly connected to the cap side wall, and at least one tearable tension bridge member can have a lifting arm which extends on the side of the associated slot facing away from the actuating lug and away therefrom along the cap side wall.
  • the lifting arm can have at least one small tear-open web towards its free end, through which it is connected to the side wall of the cap.
  • a bridge element extending on the circumference of the cap side wall can be provided, which connects the two tension bridge links to one another, and each tension bridge member can have a web that can be torn open in the tangential direction on its side located between the slot bridged by it and the bridge element. through which it is connected to the cap side wall.
  • the bridge element then preferably extends over the actuating nose.
  • the bridge element can also have at least one tearable web, by means of which it is connected to the flanks of the actuating lug fastened to the side wall of the cap.
  • the area of the bridge element located in front of the front side of the actuating lug is preferably free of webs and can be lifted upwards from the actuating lug before the first opening of the closure, the operating lug remaining in the closed position until the web connection connects at least one of the tension bridge members to the cap side wall is torn open on at least one side of the slot it bridges. Only then does the actuating nose lift off with light finger pressure when a slightly greater force is required than is necessary to tear open the webs.
  • the slot cap closure according to the invention can also have a number of improvements, regardless of the tear-open bridging of one or more slots.
  • the sharp lower front edge of the latter cuts into the lifting finder and can make lifting off painful.
  • a lifting bead of preferably semicircular cross section is provided on the underside of the actuating lug, one side wall of which is flush with the end face of the actuating lug, so that the sharp front edge on the underside of the actuating lug is eliminated.
  • the two support struts on the top of the actuating lug are extended practically to the circumferential edge of the cap surface, so that when the finger is pressed onto the lifting bead on the underside of the actuating lug, not only the lowest area of the cap side wall up to the inner ring bead in the area of the actuating lug is raised somewhat , but the entire front area of the cap side wall with the area of the inner ring bead located therein is slightly bent forward and upward away from the bottle mouth.
  • the cap side wall of the proposed closure is slit one or more times in the axial direction from the lower edge of the cap to close to the roof wall.
  • the cap side wall therefore fails for the sealing function of the closure.
  • This sealing function must be performed by a spout attached to the inside of the roof wall and extending into the bottle mouth.
  • This spout is preferably long, approximately the same height as the inner height of the closure cap. If the lower area of the spout is concavely curved inwards, the spout pressing against the inside of the mouth can also take on a guiding function for the closure in addition to its sealing function when the closure is mechanically attached.
  • the slot on the side of the cap, which is present from the start, also prevents air from getting out when the closure is put on is pressed from the outer interior of the cap into the space above the liquid level of the bottle; the container or bottle can therefore be filled relatively well, there are no unnecessary air cushions between the cap and the liquid, which can only have an advantageous effect on the durability of the container contents.
  • the angle between the top wall of the cap and the side wall of the cap should be as rectangular as possible and the closure in this wall area is relatively stiff, ie. train thick-walled. Rising internal pressure leads to bulging of the cap top wall, this bulging the top of the cap outwards leads to an increase in the pressure of the inner ring bead of the cap side wall against the constricted underside of the muzzle bead due to the retention of the above-mentioned angle, so that increasing internal pressure leads to an increasingly firm fit of the cap on the bottle .
  • the cap 80 has a roof wall 80a and a cap side wall 81.
  • the latter has two slots 82 and 83, which extend in the axial direction from near the roof wall 80a to the lower peripheral edge edge 80b of the cap side wall 81, in which they open.
  • the two slots 82 and 83 are each offset by 60 ° to the opposite side of the cap 80 from the actuating side on which the cap 80 carries an actuating lug 88 with two stiffeners 88a.
  • a tension bridge member 84 and 85 is provided adjacent to the cap circumferential edge 80b, bridging the slot 82 and 83, articulated on both sides of the slots 82 and 83 to the cap side wall 81.
  • the lower peripheral edge 80b passes the mouth bead 11 of the bottle while spreading the slots 82 and 83 and simultaneously stretching the tension bridge members 84 and 85. If the inner ring bead 89 is pressed over the mouth bead 11, they pull Tension bridge members 84 and 85 by compressing the open ends of the slots 82 and 83 together and thus increasing the pressing of the surface of the inner ring bead 89 against the constricted underside 11b of the mouth bead 11 on all sides.
  • a grommet 86 is provided on the inside of the cap roof wall 80a.
  • the roof wall 80a has an indentation 87, which contributes to increasing the pressure of the inner ring bead 89 against the constricted underside 11b of the mouth bead 11 with increasing internal pressure in the bottle mouth.
  • the outer wall of the spout 86 can be provided with a number of parallel annular beads 86a (FIG. 4), by means of which a seal similar to a labyrinth seal is achieved with the end face 11 of the mouth with the end face 11 of the mouth.
  • the cap 80 has a sleeve 90, which is preferably connected in one piece to the cap 80 via a hinge 91.
  • the tensioning bridge member 84 is articulated to the side wall 81 near the lower cap circumferential edge 80b via a thin connecting web 92.
  • the end 84a, 85a of the tensioning bridge member 84, 85 which is directed away from the actuating lug 88 is designed as a tear-open flap and is only formed by small, short ones Bars 93 with the cap side wall 81 connected and ends in a tear-off tab 84b, 85b projecting somewhat from the cap side wall 81.
  • the slots 82 and 83 should be spread, but can do so only relatively slightly, since they are essential due to the tension bridge members 84 and 85 under strong tangential tension of the latter be kept tighter than would be the case with free, tension-free spreading.
  • the tangential tensioning of the clamping bridge members and thus the sealing fit of the cap on the bottle mouth becomes so firm that on the one hand it has 6 to 8 atmospheres or more inside the bottle and even sterilization of the Bottle contents with the bottle closed while increasing the temperature to 62 ° C for at least 20 minutes, but on the other hand in the machine state by pressing a finger, e.g. of the thumb, against the front and underside of the actuating nose 88 can no longer be adjusted or only with great effort.
  • the end 84a of the tension bridge member 84 is therefore detached from the side wall 81 of the cap by lifting off the tear-off tab 84b and tearing off the short webs 93 and then the connecting web 92 which is longer along the lower edge of the cap circumference 80a the slit 83 bridged by the tension bridge member 84 can spread further, as a result of which the pressure of the inner ring bead 89 against the constricted underside 11b of the mouth bead 11 of the bottle is reduced so much that the cap 80 still sits sealingly on the bottle, but by proportionality slight pressure can be lifted from the bottle mouth 10 with a finger against the actuating nose 88.
  • the second slot 82 can also be released by tearing the tension bridge member 85 over its end 85b and the webs 93, 92.
  • the cap 80 To put the cap 80 back on the bottle mouth 10, the strong impact pressure of a filling and closing machine is no longer required, but the cap 80 can now be placed on the bottle mouth 10 in a sealing manner by pressure with the thumb.
  • the cap 80 then still hermetically seals the remaining contents in the bottle from the outside air, but of course it can no longer withstand pressures from several atmospheres. However, she no longer needs to do this, since part of the liquid bottle content has already been removed, so that there is a much larger gas space above the liquid than a buffer, and re-sterilizing the bottle content is of course no longer an option. Rather, the bottle content should be used up as soon as possible. After all, the cap is still so tight on the bottle that it can be put on its side or even turned upside down without the cap being pushed off and the contents of the bottle flowing out.
  • the connecting webs 92 and 93 of the ends 84a and 85a of the tension bridge members 84 and 85 which have not yet been torn open indicate that the bottle has not yet been opened for consumption. So they serve as a guarantee seal.
  • both tensioning bridge members 84 and 85 are provided with tear-off ends 84a and 85a, which have the outer circumferential regions 82a and 83a located next to the slots 82 and 83 and facing away from the actuating lug 88 of the cap 80 via longer connecting webs 92 and 94 as well as via shorter connecting webs 93 and 95, which are more distant from the slots 82 and 83.
  • a bridge element 97 which connects the two tension bridge members 84 and 85 to one another, is provided around the actuating lug 88 and is connected to the flanks 88c and 88d of the actuating lug 88 by means of short connecting webs 98.
  • the two tension bridge members 84 and 85, together with the bridge element 97 connecting them, can be completely separated from the cap side wall 81 and the actuating lug 88.
  • the separation is further facilitated by a gap 99 remaining between the end face 88e of the actuating lug 88 and the bridge element 97 during the manufacture of the cap 80.
  • the tension bridge members 84 and 85 in the circumferential areas 82a and 83a of the cap side wall 81 facing away from the actuating lug 88 are fused with the latter in a tapered manner and cannot be torn off.
  • the tension bridge members are open the areas located towards the actuating lug 88 next to the slots 82 and 83 can be torn off by means of the thinner connecting webs 96a and 96b which extend longitudinally at the peripheral edge, the tensioning bridge members 84 and 85 being connected to one another via a bridge element 97 already mentioned, in the manner already described is connected to the flanks 88c and 88d of the actuating lug 88 by means of short tear-off webs 98, while the gap 99 remains between the end face 88e of the actuating lug 88 and the bridge element 97.
  • this gap 99 extends so far around the end face 88e of the actuating lug 88 up to its side flanks 88c and 88d that the bridge element 97 is lifted off with the fingers and on one or both sides to one or both of the slots 82 and 83 can be torn open, wherein the tip of the tearing finger can be inserted into the bridge element 97, which then forms a bow.
  • bridge element 97 and tension bridge members 84 and 85 naturally remain connected to the cap side wall 81. Again, however, the webs 96a, 96b and 98 which are torn open can easily be seen that the bottle closed with the cap 80 had already been opened once.
  • the actuating lug can now be designed much shorter than in the embodiment of FIGS. 27 to 31 of German Offenlegungsschrift 2554887. This means a very considerable saving in material when manufacturing the cap.
  • the shortening and simultaneous blunting also offers advantages when pre-sorting for the capping machine when filling.
  • protruding nose one nose fell on top of the other, and thus some closures slanted, which hindered the feeding.
  • the inner ring bead 89 of the side wall 81 of the cap 80 lies at a distance d from the inside of the roof wall 80a.
  • the latter is shown running flat here, but it can also have a flat depression, as can be seen in the embodiment of FIGS. 3 and 4.
  • the spout 86 extends almost to the lower circumferential edge 80b of the cap side wall 81, that is to say it is considerably longer than in the embodiment of FIGS. 1 to 6.
  • the outer side wall 86c of the spout 86 is above all to the inside of the 'cap side wall 81 bulged out so that it approximately describes a spherical zone in its central area.
  • the cross-sectional area of the largest outer diameter f of the grommet 86 extends at a distance e from the inside of the cap roof wall 80a that is greater than the distance d of the area of the smallest clear width of the inner ring bead 89.
  • the inside 86b of the grommet 86 is also one Descriptive spherical zone, but convex.
  • the actuating nose 88 has along its front edge on its underside a lifting bead 102, the outward side flank 103 of which is rounded.
  • the lifting bead 102 is separated from the lower peripheral edge 80b of the cap side wall 81 by a depression 104 which can be open to the side of the lifting bead 102. As a result, the lifting bead 102 does not protrude beyond the lower peripheral edge 80b of the cap side wall 81.
  • the actuating nose 88 is stiffened on its upper side by two support struts 88a, which extend approximately up to the roof wall 80a of the cap 80.
