Definitions

  • the invention relates to a tamper-evident closure for a container with external threaded elements and a bead which extends around the circumference and is directed radially outwards and which has a cap region of a dome-like shape, and to a tamper-evident band which is connected to the lower, trailing edge of the cap region by a series of circumferentially spaced frangible bridge connections.
  • Tamper-evident closures preferably made of plastic, are not new as such.
  • the known designs eg US Pat. No. 4,432,461; US Pat. No. 3,329,295
  • tamper-evident band usually have a cup-like shape with an internal thread which interacts with a thread on a container and usually have a tamper-evident band (hereinafter referred to as tamper-evident band). or such a ring, which is attached to the lower end edge of the cap lower part and is connected to this by a series of circularly arranged breakable bridge connections.
  • the originality band contains usually fasteners in the form of ribs, which engage below a radially outward bead or a flange below the thread of the container.
  • a disadvantage of the previously known tamper-evident closures relates to the mechanics of their attachment to the container. Ideally, the tamper-evident band expands evenly over the bottle neck or the bead. In practice, this ideal case is not achieved in many cases with the known closures. It can happen that the tamper-evident band is pulled apart upwards around the lower part of the cap or the fastenings of the tamper-evident band on the lower part of the cap are pulled by an excessive lateral displacement (see Fig. 16-19). Because of this uneven deformation of the bridges, there is a risk that a during the installation B takes back or break during removal of damaged bridges break too early, which then causes the ring.
  • the one-sided sliding of the tamper-evident band is also known as a typical faulty mechanism, particularly when the cap is attached to the container.
  • those ring ribs which hold the part of the tamper-evident band which has slipped over the bead of the container are partially pulled, while those ring ribs which connect the remaining part of the tamper-evident band to the lower part of the cap are partially compressed.
  • This latter effect can also result in cap assembly failure.
  • the one-sided slipping of the tamper-evident band reduces the torque that must be used to attach it in the faultless case. For this reason, there is a risk that the chuck, which is sensitive to torque, of the usually automatic assembly equipment will be incorrectly controlled and the cap will be released even before it is completely arranged on the container.
  • the snap ring closure is generally designed in such a way that the circumferential torsional forces which are exerted on the connecting bridges when the cap is removed due to the locking effect of the bottle bead are greater than the combined tearing force of the latter Bridges.
  • this "tear condition" is common in practice not reached.
  • This object is achieved in particular in that there is a radially inwardly directed retaining rib on the inner surface of the tamper-evident band, which is in operative connection with the container bead, and that a series of upward projections are arranged on the tamper-evident band between the bridge connections, which the Axially apply the overlying cap part when placing the closure on the container.
  • the lateral displaceability of the tamper-evident band during initial assembly on the Container significantly prevented.
  • the structured configuration of the container bead prevents the tamper-evident band from slipping unevenly after the bead apex has been overcome. Because this prevents an uneven and thus locally excessive loading of the bridges, the originality band, including its bridge connections, can relax to the extent of its original and natural dimensions (at the time before assembly). This will be the advance Sections for a clean and even break of the connection points when screwing on significantly improved.
  • the container has outer threaded elements and a circumferentially extending, radially outward bead below the threaded elements, the bead having a structure with at least one circumferentially extending recess near it Crown of the bulge. It is expedient if the radially inwardly directed retaining rib on the inner surface of the tamper-evident band can be snapped into the recess when the closure is rotated to open the container.
  • the first opening of the tamper-evident closure is further facilitated if the apex of the bead is followed by a frusto-conical lower guide surface converging downwards in the direction of the container bottom. It is useful if the frustoconical guide surface converges at an angle of approximately 30 to 45 ° to the plane running transversely to the container axis.
  • the invention also relates to a method for producing a tamper-evident closure.
  • This object is achieved in particular by first forming a one-piece closure from plastic material which has an upper part and a lower part which is connected to the upper part and a radially inwardly directed rib near the lower end edge of the tamper-evident band and an annular region of smaller cross-section between the Lower part of the cap and the tamper-evident band, and that subsequently a plurality of bridges arranged around the circumference and inwardly angled projections is formed by a slitting and pressing process in the region of the side wall of the closure lying between the tamper-evident band and the lower part of the cap.
  • closure cap can be molded in one piece, as is customary, and consequently there is no need to subsequently assemble individual cap parts.
  • the tamper-evident closure in the area between the tamper-evident band and the lower part of the cap is guided with its outer wall over an arcuate knife consisting of blade segments, which cuts through the wall of the caps in the areas provided for this purpose and against one inside the Cap located molding plate presses.
  • the method according to the invention allows the cap to be slit and the bridges to be shaped in both hot and cold condition and can therefore be applied to all common plastics.
  • the process is also very flexible.
  • Bridge geometry and thickness can be varied by simply changing and adjusting the cutting knife.
  • the knife can, for example, be arranged so that there is an incision or a Leaves a notch on the shaped bridges in order to predetermine breakpoints or to reduce the refractive power. In this way, for example, bridges varying in thickness around the cap circumference can also be produced.
  • the invention also relates to a device for carrying out a method of the type mentioned at the outset. It is particularly characterized in that it has a preferably rotatably mounted guide pin and a mold plate connected to it, which has a bevelled peripheral edge as an abutment for the pressing process, the diameter of the mold plate corresponds approximately to the inside diameter of the cap in the area between the lower part of the cap and the tamper-evident band area.
  • a tamper-evident closure generally designated 1o.
  • the closure comprises essentially a cap 12 dome-like shape with an internal thread 14 in the cap upper part 12a which engages with the thread 16 of the container surface, and a tamper-indicating band 18, which concluding with the lower Edge of the lower part of the cap 2o is connected by a series of breakable bridges 22.
  • the container opening generally designated 3o, contains a standard thread 16 near the outlet opening 32, a bead 34 which retains the tamper-evident band 18, which is arranged below the thread 16, and a second bead 36 which is arranged axially below the tread 34 holding the tamper-evident band 18 ( see Fig. 13).
  • tamper-evident closure 1 0 Considering the structural details and the composition of tamper-evident closure 1 0 according to the invention, it can be seen in Figures 3 and 4 show that for the tamper-indicating band 18 (tear strip) is provided a cross-section which is larger than that at the final lower edge of the cap bottom part 2o is adjoining intermediate region 40, in which the bridges 22 designed as predetermined breaking points are formed and in which the tamper-evident band 18 has an enlarged cross section, in which a holding rib 44, which extends in a circle and is directed inwards, is contained.
  • the tamper-evident band 18 comprises a first section 42a of a substantially triangular cross section and a second section 42b of a substantially rectangular cross section.
  • the stability achieved by this cross-sectional shape prevents the tamper-evident band 18 from expanding particularly during the initial opening, so that it can be retained practically safely by the bead 34 while the bridges 22 break.
  • the cap 12 also contains a row of circularly arranged projections 50 or the like. Lip areas which, as shown in FIG. 4, are chamfered slightly inwards and act on the shoulder 52 during the initial assembly, which is formed on the lower edge of the lower cap part 20 . As a result, the originality band 18 is stabilized in a horizontal position in this phase, so that the bridges 22 are not pulled apart on one side or the originality band 18 is not moved laterally. By absorbing the compression forces that are exerted on the tamper-evident band 18 during the initial assembly as soon as it is pressed over the container neck or the bead 34, the projections 5o thus lead to the prevention of excessive band and predetermined breaking point voltage imbalances.
  • the projection 5o extends radially inwards with a correspondingly determined angle alpha ( ⁇ ), so that its beveled end face 51 lies under the shoulder 52, and that the lower end edge 53 is mounted during the mounting of the cap on the container of the cap bottom part 2o on the outer beveled end face 51 of the projection 5o.
  • the pressure point lies approximately at the center 5oa of the projection 5o (cf. FIG. 14a) in order to thereby center the tamper-evident band relative to the cap and to prevent its lateral displacement, as shown in FIG. 17.
  • the holding bead 34 which is arranged on the container below the thread as best shown in FIGS. 13 and 14, has a truncated cone-shaped upper guide area 6o and a circularly extending first recess 62 which extends between the holding bead 34 and the bead 36 is arranged.
  • the arcuate frustum base of the upper guide area 6o forms an apex, designated 66, which forms the largest diameter of the upper guide area 6o.
  • the lower section of the bead 36 has an inverted frustoconical section which serves as a lower guide area 64 under the recess 62.
  • the upper guide area 60 merges with the base apex 66 in an arcuate upper connecting wall 67, which has a radius of curvature R 1 suitable for mounting the cap.
  • the lower guide area 64 also merges into a lower arcuate connection area 68 with a suitable radius of curvature which facilitates the displacement of the tamper-evident band 18 into the horizontally secured position of the recess 62.
  • the inner diameter Dr of the rib 44 and the maximum diameter D1 of the retaining bead 34 are in such a fixed relationship to one another that the rib 44 can slide over the upper guide area 6o and engage above the lower guide area 64 as soon as the cap finally fits the figure 15a and in the phantom line in FIG. 13.
  • the number of predetermined breaking points will increase with the cap diameter, e.g. B. for 33 mm (cap diameter) 10.
  • the arcuate connecting wall 67 which has a fairly large radius of curvature Rl approaching the apex 66, provides a mechanically advantageous attachment of the cap 12. Namely, when the band 18 is extended when moving over the upper guide section 60, the torque required to move the tamper-evident band 18 to the apex 66 when screwed on increases to the extent that the band is stretched. As soon as the holding rib 44 moves towards the rounded section near the apex 66, however, the torque increases more slowly and remains essentially the same during the further slight expansion of the tamper-evident band until it exceeds the apex 66.
  • some of the bridges 22 may break if the band is stretched as it passes the frusto-conical lower guide portion 64 before it reaches a position where the rib 44 in the recess 62 is held above the bottle neck bead 36.
  • the holding rib 44 is in this case below the recess 62, while the rest of the holding rib 44 runs and lies in the recess 62. The bridges 22 then initially remain intact in this recess.
  • the container neck diameter D 4 below the lower guide region 64 preferably corresponds approximately to the diameter Dr of the band rib 44 in a relaxed state and thereby keeps the band 18 in a tensioned state.
  • FIGS. 14 a and 14 b show the sequence of the first assembly of a closure arrangement 10 according to the invention. It can be clearly seen here that the respective conical side surface 51 of the projections 50 presses on the associated shoulder 52 on the lower end edge of the lower cap part 20 in order to pull apart unevenly of the tamper-evident band 18 when the cap 12 is first installed and to prevent the bridges 22 from breaking prematurely.
  • the projections 50 are also arranged in such a way that lateral movement of the tamper-evident band 18 is prevented, which would tend to load the connecting bridges 22 in an uneven manner and would promote band jamming.
  • the holding rib 44 is located somewhat below the lower guide region 64 of the holding bead 34. If the container is now to be opened for use, the cap 12 is simply rotated in the opening direction, the rib 44 slides over the lower guide area 64 and snaps into the circularly extending recess 62. Through this process, the tamper-evident band 18 is temporarily held in a horizontal position in order to bring about a substantially uniform breaking of all bridges 22 as soon as the cap top part 12 moves axially upward with further rotation in the opening direction. The tamper-evident band 18 is now initially held in the recess 62 with its holding rib 44 when the container is open. However, if the cap is put back on, the shoulder 52 acts on the projections 50 and displaces the tamper-evident band so that it lies loosely below the container bulge 34 and the flange 38.
  • the second recess 78 has a diameter D 5 which is substantially equal to the diameter Dr of the rib 44, whereby the tamper-evident band 18 can relax after the application, but at the same time an excessive displacement of the band 18 is avoided in the event that premature Breaking the bridges 22 should prevent the entire rib 44 from reaching the secured position of the recess 62.
  • bead 34 or the profile on the container does not have to be guided continuously around the circumference, but can also be interrupted.
  • FIGS. 6 to 8 show a method and a device for producing the closure arrangements 10 according to the invention.
  • 6 schematically shows a system or a method for shaping the bridges 22 and projections 50 in closure arrangements 10 according to the invention.
  • three process stations are shown.
  • Each station includes a feed station Sf to feed unslotted caps 12, face up, to a guide pin M which engages cap 2 internally and over the arcuate cutting edge of a cutting blade 80 of a substantially circular shape Au ⁇ baues turns.
  • the guide pin M rotates the cap 360 "(clockwise) to form all the bridges 22 and then remove the molded cap 12 from the guide pin by gas pressure.
  • the cap 12 is in a marginal position by the guide pin M.
  • of the pressure plate 90 has been rotated so as to be conveyed from the guide pin M to a collective transport device or the like by means of air nozzles.
  • the intermediate region 40 which connects the lower cap part 20 to the holding rib 44, is shaped with a certain uniform cross section, preferably from 0.008 inches corresponding to 0.023 cm to 0.025 inches corresponding to 0.064 cm.
  • the caps of this shape are then guided to a molding station for the bridges 22 and the projections 50, in which an abutment engages inside the cap 12 in the manner shown in FIG. 7. As shown, the caps 12 are placed with the open side up against a pressure plate.
  • the abutment includes a forming area 76 which faces the inner surface of the intermediate area 40 and which rotates the caps 12 via a segmented cutting blade 80 with the cutting tooth arrangement shown in FIG. 8.
  • a cutting knife is shown with a substantially arcuate shape.
  • the blade 80 is close to the molding area 76 and, due to the relative rotation of the cap 12 and the blade 80, produces the circularly arranged bridges 22 and the inwardly inclined projections 50, which are molded in by a pressing process.
  • the cutting blades 80 can have beveled end edges 94 in order to ensure a clean cut and to prevent the cap 12, 20 from their entire length is scored.
  • the elements and arrangement of the mandrel M are best illustrated with the aid of FIG. 7. They contain a drive wheel 70, to which rotatable planet wheels 72 are attached and which in turn rotate about a fixed sun wheel 74. As shown, the abutment 76 is fixedly attached to the planet gear 72 so that the running of the drive gear 70 causes a rotational and clockwise rotation of the entire arrangement of the guide pins M over the stationary cutting blade 80.
  • the guide pin M as shown, has a shear plate 82 and a mandrel 84 which, as shown, cooperates with the cutting blade 80 to form the projections 50 by a cutting press operation.
  • the cutting blade 80 is each mounted between holding blocks 86 and the cap 18 normally faces a pressure plate 90 during the cutting and shaping process.
  • the top trailing edge 96 of the arcuate cutting blade 80 has a series of equally spaced notches 98. While these form the bridges 22, the arcuate segments 100 therebetween are used to form the projections 50, in which the guide pin M guides the cap 12 over the blade surface .
  • the incisor arrangement can e.g. B. be carried out so that notches 98 are formed in the bridges 22 near the lower edge of the cap 12 in order to produce a predetermined breaking point section of a smaller cross-section at this point, and thus also breaking all bridges near the lower edge of the cap lower part 20 when first opened to reach.
  • This arrangement can also give the cap 12, 20 a more aesthetically pleasing exterior.
  • targeted notching of the bridges 2 ? a more precise setting of the bridge strength and thus the tear-off forces for separating the tamper-evident band can be achieved.
