Definitions

  • the invention relates to a closure cap for beverage bottles which have an edge bead with an annular axial end and an annular groove which lies at the transition point of the edge bead in the bottle neck, and in which the drink in the bottle is subjected to effects after the cap is put on, which cause an increase in the internal pressure in the space above the beverage
  • which closure cap has a base body which fits over the lip of the bottle and can be brought into contact with the annular groove with its side wall, the essentially cylindrical side wall of which merges into a cover wall via its rounded transition zone Transition zone forms a seat inside for a seal, which covers at least an upper portion of the inner surface of the side wall and extends radially inward along the top wall at least to such an extent that the seal rests on the axial end of the bottle when the closure cap is in place, with the lower edge d he 9.ivand runs along a fraction of its circumference with a rag, which forms an integral part of the base body from sheet metal, initially an extension of the side wall and is then
  • Such caps are known as closures for glass bottles, particularly reusable bottles, both for alcoholic beverages, e.g. Beer, as well as for soft drinks.
  • the shape and size of the mouth of such bottles are standardized, e.g. according to DIN 6094.
  • elevated temperatures are necessary for sterilization. For example, temperatures of about 72 ° C are used in the sterilization of beer, and temperatures between about 123 ° C and 133 ° C are used in the sterilization of gas-free cupboards, these temperatures being maintained for a longer period of time.
  • elevated temperatures are also suitable during transport and storage, e.g. by sun exposure, often not avoid.
  • caps have two mutually parallel tear lines that run vertically upward as an extension of the side edges of the tear tab on the side wall of the closure cap and also extend over the top wall of the closure cap. These caps also do not allow automatic pressure reduction, since this requires a certain amount of stretching of the jacket part of the cap in the circumferential direction, which in the described cap construction leads to bursting at the weak points of the cap material formed by the tear lines. In addition, such caps have the disadvantage that often after the opening of the remaining part of the cap at the bottle mouth and must be removed separately.
  • the invention has for its object to improve a closure cap of the type described above so that the pressure reduction takes place reliably, and there is a reliable seal of the bottle cap again after the excessive pressure has been reduced.
  • the invention solves this problem in that, in the case of a closure cap of the construction described at the outset, in the tear tab area in the side wall to stabilize a blow-off effect in the event of overpressure, there is at least one outwardly curved bead running essentially parallel to the axis of the closure cap.
  • This bead forms an irregularity in the form of a fold in the material of the cap wall at its ends, in particular at the upper end, so that a locally limited weak point of the seal is formed there, at which the pressure reduction can be carried out reliably and, if necessary, several times, after which each time the pressure is reduced there is a sealing reclosure of the bottle, which generally does not take place after the overpressure has been completely eliminated, but only when the overpressure has reached an innocuous value has dropped, for example from 10 bar to 5 bar.
  • This pressure reduction takes place without the risk of tearing open the closure cap wall, since the special type of guidance of the tear line prevents the closure cap from tearing along the tear line when the pressure is reduced.
  • closure cap according to the invention can also be easily applied to bottles during the closure process, only relatively low pressures being required to achieve the necessary seal. The risk of bottle breakage in the capping machine is therefore reduced and the closure cap according to the invention can even be used for plastic bottles.
  • the beading can also result in advantages when the bottle cap is opened by the user, since during the opening process the weak point mentioned can cause a partial reduction in the overpressure in the bottle before the remaining overpressure can lift the cap off the bottle.
  • the risk of the cap being thrown off the bottle mouth and the risk of a part of the bottle contents being thrown out under the action of the suddenly decreasing excess pressure in the bottle is therefore reduced.
  • the bead ends below the tear line.
  • the bead and the tear line intersect, the acute crossing angle being more than 45 °. In both cases it is avoided that the tearing process follows the bead instead of the tear line.
  • the tear line extends at least to a point which is offset from the starting point of the tear line by approximately half the circumference of the iron wall.
  • the further tear line section runs at a height which is at or slightly above the height at which the largest outer diameter of the edge bead lies. If neither of the two tear line sections extends to the rounded transition zone and the tear line ends with the further section at a distance below the top wall but in the side wall, the cap remains one-piece even after the tear process, i.e. the tear flap is connected to the remaining rope of the closure cap even after the tear-open process and the cap character is also retained. It is therefore possible to put the cap back on the bottle mouth after removing part of the beverage and thereby achieve a certain limited protection of the remaining bottle contents.
  • the connecting zone 16 forms a seat 13 (Fig. 2a) for an annular elastic seal 18, in particular made of polyethylene, PVC or other thermoplastic material, which retains its elasticity even at cooling temperatures to which drinks are normally exposed and which does not soften at elevated temperatures to which drinks are normally exposed during sterilization.
  • the sealing ring 18 preferably consists of a plastic foam which is let into the seat 13 in liquid form and is cured there by heating.
  • the seal 18 can also be a full sealing disk which completely covers the bottom surface of the top wall 14. However, it is more advantageous if the seal does not extend in the radial direction inward far beyond that area which lies against the mouth of the bottle (FIGS. 6, 7).
  • the side wall 12 of the cap which is pressed inward when it is placed on the bottle, is essentially cylindrical in the manufacture of the cap from a sheet by stamping and deep-drawing.
  • the lower edge 20 can be slightly unwound outwards (FIG. 2a), which makes it easier to put the cap on the bottle mouth during the closure process.
  • a tear tab 22 is formed in one piece with the side wall 12, the free end of which protrudes approximately horizontally from the closure cap 10 after it has been formed (FIG. 2).
  • the length of this tear tab 22 is selected so that it can be comfortably gripped by the user for the purpose of tearing open the closure cap.
  • this tear flap 22 is so long that it extends with the closure cap applied down over that bottle bead which lies immediately below the rim bead of the bottle. In this way, the Tear flaps 22 are easily pulled off the bottle neck during the opening process.
  • the tear sheet 22 has a section 24 which forms a continuation of the side wall 12 downward and thus, as it were, an addition which prevents the tear tab from being deformed inadmissibly when the closure cap is pressed onto the bottle when it is placed on it.
  • the end 25 of the tear tab 22 can be rounded (FIG. 1).
  • the tear tab extends along the circumference of the side wall 12 only over a fraction of the same. Its transition points in the lower edge 20 of the side wall 12 are rounded.
  • a tear line 27 runs approximately around half the circumference of the side wall 12.
  • This tear line 27 has three sections 28, 29, 30, which in the embodiment according to FIGS. 1 and 2 merge continuously into one another.
  • the tear line 27 has its starting point 26 at the rounded transition point between the tear tab 22 and the side wall 12 and its first section 28 rises at an acute angle to the horizontal plane.
  • the second section 29 runs flatter upwards towards the top wall 14 and then horizontally and merges into the third, also horizontally running section 30, which runs somewhat around the top wall 14 about half the circumference of the side wall 12.
  • the angle which the tear line sections 28, 29 form with the horizontal plane should be less than 75 °, preferably less than 45 °, e.g.
  • the tear line section 30 should be arranged so deep, approximately 2.5 mm below the top surface 14, that the majority of the seal 18 is not disturbed. In this way it is assured that the seal 18 remains intact for as long as possible during the opening process.
  • the arrangement should also be such that below the tear line 27 there remains a strip which absorbs the tensile forces when the closure cap is opened, the width of which should be about 2 to 3 mm.
  • the tear line 27 ends approximately 140 to 180 ° opposite the starting point 26 at the same height as the section 30.
  • the length of the tear line 27 should be large enough to be able to easily remove the closure cap from the bottle after passing through the tear line.
  • the tear line 27 is formed in the material of the closure cap 10 during its manufacture, namely that it is incorporated into the sheet metal blank in the flat state thereof before the closure cap 10 is deep-drawn into its final shape. Using a suitable tool, the tear line is formed as a groove, the bottom 34 (FIG. 3) of which is flat. The material in the area 36 under the tear line 27 may be hardened when the tear line 27 is formed, so that the pulling off of the tear tab 22 along the tear line 27 is facilitated without adversely affecting the overall strength and thereby the sealing behavior of the closure cap 10.
  • the groove forming the tear line 27 is open to the inside of the side wall 12.
  • the tear tab 22 has on its inner wall a bead 38 '(FIG. 2) in the form of a U-shaped bulge which forms a rib 38 on the outside of the tear tab 22 which reinforces the tear tab 22.
  • the ends 40, 42 of this rib 38 are substantially higher than the lower edge 20 of the side wall 12, but do not cross the tear line 27 and do not extend into the seal 18.
  • the material of the closure cap has an accumulation of wrinkles, even after the cap has been applied to the bottle, so that when a predetermined internal pressure occurs, the excess pressure, especially in this area, is reliably released, whereupon the cap seals properly again.
  • This blow-off effect can be optimally adjusted by a suitable choice of material in connection with the design and type of the closure cap. Versions tried and tested in practice blow off between 8 and 10 bar, the internal pressure in the bottle being reduced to about 5 bar and then sealed again. These embodiments consisted of a deep-drawn aluminum cap made of an aluminum sheet with a thickness between 180 and 190 microns, since its tensile strength was between 120 and 160 Newson / mm 2 . The aluminum was 99% pure. Under normal transport and storage conditions, the internal pressure in beverage bottles is up to around 6 bar, but shaking and / or heating the bottle can result in an internal pressure of over 10 bar.
  • the closure cap When the closure cap is applied to a beverage bottle of the type described at the outset, the cap is held in a sleeve provided with fingers and placed on the bottle with it. Then will
  • the cap is pressed against the bottle mouth at such a pressure that the material of the seal is compressed elastically. Sodar.n the sleeve is pulled together around the beaded edge of the bottle and presses the lower edge 20 of the side wall 12 of the cap into the annular groove between the beaded edge and the subsequent bottle bulge with the formation of folds. At the same time, the transition zone 16 is pressed against the rounded profile of the bead edge of the bottle, the radius of curvature of the transition zone 16 being increased.
  • the stresses that occur during these processes like the manufacture of the closure cap, result in material hardening caused by cold deformation of the metal, which is essentially uniform over the circumference of the closure cap.
  • the selected material hardening and the associated increase in the elasticity of the fibers favor or in the first place enable the described blow-off effect to occur, because there is a slight expansion of the closure cap and / or an increase thereof with respect to the bottle neck during the blow-off , so that part of the gas can escape from the bottle, with this expansion of the cap the material must remain in the elastic range.
  • the elasticity of the cold-hardened sheet metal of the closure cap then leads it back into the sealing starting position.
  • FIG. 4 is similar to that of FIG. 1 with two exceptions.
  • the first difference is that the end 25 of the tear tab 22 extends in a straight line, but obliquely with respect to the two side edges 48, 50, so that the side edge 48 closer to the starting point 26 of the tear line 27 is longer than the other side edge 50. This causes the user to grasp the tear tab closer to the side edge 48 and pull it to the right so that the tear along the tear line 27 begins in the correct direction, although the tear line 27 is not visible to the user since it is is on the inside wall of the cap.
  • the second difference is that the upper end 42 of the rib 38 extends up to the area of the top wall 14. In this way, a weak point is formed there in the seal 18, since the bead 38 ′ located on the inside of the cap on the rear of the rib 38 in the region of the end 42 forms a channel-like connection from the seal 18 to the tear line 27. Even if the material of the seal 18 should fill this bead 38 ', its upper end (at 42) nevertheless forms the weakest point for the escape of excess pressure from the inside of the bottle when the cap is opened, since the seal 18 is located at this point pressure against the bottle mouth is lowest. The gas from the bottle has therefore already escaped when the tearing process of the tear tab 22 has ended, so that the excess pressure in the bottle is then completely eliminated and the closure cap 10 cannot therefore be thrown off.
  • the other leg of the U-shaped rib 58 (FIG. 4) does not extend so far upwards with its end 40 and does not cross the rising section 28 of the tear line 27.
  • a cross between this end 40 of the rib 38 and the tear line 27 may only essentially exist in the latter horizontal sections 29, 30 occur.
  • the bottle of which only the uppermost section is shown, consists mostly of glass, but possibly also of plastic.
  • the bottle 62 has at its upper end an edge bead 64, the end 66 of which has a somewhat flattened central section, but is otherwise rounded.
  • the outer surface of the bead 64 is drawn inwards and ends in an annular groove 68 on the bottle neck. Below this annular groove 68 there is a bulge 70 for reinforcing the bottle neck.
  • This bottle shape is standardized worldwide, whereby in almost all cases the maximum diameter of the edge bead 64 is approximately 26.5 mm.
  • the inside diameter of the side wall 12 of the closure cap is now chosen such that it fits snugly on the bottle end in the first step of its application.
  • the side wall 12 is pressed in under the bead 64, only a small axial pressure is required.
  • the bottom of the side wall 12 has, despite the wrinkling of the material, practically invisible grooves, so that a label remains clearly legible, even if it was applied to the metal sheet before the closure cap was formed.
  • the tearing process begins at the starting point 26 of the tearing line 27 by pulling the tearing flap 22 to the right (FIG. 9). 5 and 7 it can be seen that the end 40 of one leg of the U-shaped rib 38 extends almost to the tear line 27, the other end 42 even beyond. Correspondingly, the bead 38 'also extends (FIG. 7). As a result of the greater length of the leg of the rib 38 leading to the end 42 compared to the embodiment according to FIG. 1, greater wrinkling occurs in the side wall material of the cap, these folds reaching as far as the seal 18, so that a limited weak point of the seal is formed there.
  • the tear tab 22 has a U-shaped rib 38, which, however, does not extend to the tear line 27 and mainly serves to reinforce and reinforce the tear tab 22.
  • An additional, central rib 38 serves to relieve the pressure prevailing in the bottle. This central rib 38 crosses the tear line 27 approximately in a right-angled manner and extends in the side wall 12 up to the upper part of the rounded transition point 16 and therefore to the seal 18 in
  • the tear tab 22 is shown partially pulled away, the upper portion of the rib 38 being separated from its lower portion. Arrows indicate how the gas escapes via the channel formed by the upper section of the rib 38 and / or in the vicinity thereof, so that the overpressure in the bottle is reduced during the opening process, even though the remaining part of the closure cap 10 is still on the bottle .
  • Fig. 10 shows a development of a part of the sheet metal blank for the closure cap 10 in plan view, before the formation of the closure cap.
  • a bead 38 ' is provided on the inside of a rib as in the embodiments according to FIGS. 8 and 9.
  • the parallel dashed lines 102, 104 represent the section in which the seal 18 will lie.
  • an adhesive e.g. in the form of a lacquer, applied to the surface of the sheet essentially only in the zone 106 lying between the two lines 102, 104, which has an interruption 108 over part of its circumference in the region of the bead 38 '. In this way it is ensured that the seal 18 does not adhere to the bead 38 ', although this bead is filled with the sealing material.
  • the gas can escape between the seal 18 and the axial end 66 of the bottle. It is believed that the elasticity of the side wall 12 allows a slight expansion of its lower edge 20 when the cap is slightly raised along the bead 64. With this lifting of the sealing cap, the gas can flow in under the seal 12 and emerge along the side wall 12 of the sealing cap 10 in the region of the weak point already mentioned which is caused by the fold formation in the material of the side wall.
  • the top wall 14 can also be arched. This bulge can be created right from the start when the cap is manufactured, as can the top wall a profile, e.g. by deep drawing, embossing or the like. The arching of the top wall 14 from its original flat shape can also occur under the influence of the forces acting on the bottle when the cap is applied and / or under the influence of the gas pressure prevailing in the bottle.
  • the tear tab can have a different shape than that shown in the drawing.
  • a single rib section forming a bead on its underside or a series of such rib sections can be provided in the tear tab or above it, in all cases a gradual reduction in pressure can be achieved when the closure cap is opened.
  • the tear line can also be formed by a row of perforations in the material of the side wall or at least have an interruption along its course, as a result of which the speed at which the cap is torn open along the tear line can be locally delayed or even stopped.
  • the tear line can also be formed by at least two lines running parallel to one another.
  • the invention can also be applied to steel caps which are suitably protected by corrosion-inhibiting coatings or coatings, as well as to caps made of other metals.
  • sheet metal made of aluminum or aluminum alloys is mostly preferred, since these materials are lighter than steel and are easier to tear open.
  • the transition zone 16 is to be understood as an extension of the side wall 12, so that the term “side wall” also includes this transition zone.
  • “Drink” means any liquid or pulpy food that is sold or dispensed in bottles.
