Definitions

  • the invention relates to a plastic snap lock according to the features in the preamble of claim 1 and a Process for its production. Snap locks this kind are used for closing containers, which on the outside of its approximately cylindrical mouth region have a circumferential bead. A main area of application is the closing of beverage bottles, e.g. Beer or Mineral water bottles.
  • Containers of this type are often made with crown caps Metal closed, which with the help of suitable folding devices be attached.
  • the container When the container is closed the folded cap wall overlaps the bead at the container mouth.
  • Such a closure is opened by bending the cap wall sideways with the help of a conventional cap lifter. This leads to a plastic one Deformation of the cap wall, the metallic crown cap can therefore no longer after opening the container for the first time be reliably closed.
  • EP-21 036 has therefore already been proposed instead the metallic crown cap is made of synthetic resin Capsule to use, which on the container mouth can be snapped on.
  • the resin cap has for this purpose on your inner circumference a projecting waistband, which at sealed container the bead at the container mouth overlaps so as to seal the bottle.
  • the closure is also opened with a conventional cap lifter; because the cap is made of elastic Material, it can be used in contrast to metallic crown cap without plastic deformation of the Remove the cap wall from the container mouth.
  • the cap wall is only elastically expanded and opened when opened then return to their original shape. The cap can therefore be used repeatedly and the Quality of the seal of the closure will also depend on repeated opening and closing again are not impaired.
  • EP-21 036 proposes that Reduce the thickness of the cap wall in its lower area, so that at this point when you open the container the gripper tooth of the cap lifter is deformed. Through this Deformation is shown when the container is opened for the first time.
  • the quality and reliability of this guarantee function is largely of the type used Cap lifter dependent.
  • a cap lifter with a narrow one Gripping tooth, e.g. with those contained in pocket knives Cap lifter used leads to a significant injury the lower edge of the cap wall.
  • Another option is to open a container for the first time Display snap lock, shown in GB-A-920 937.
  • a closure cap is slotted in an area of the locking beads.
  • the cap wall On the inner surface of the cap wall are along the circumference protruding, which can be snapped over a bead on the container mouth Locking means arranged.
  • the radial thickness of this locking means reached in an annular locking area of the cap wall a maximum.
  • the cap wall is expanded elastically and the locking means the cap slide over the bead at the container mouth.
  • the annular rest area and thus the thickest point of the locking means has overcome the bead, snaps the cap onto the container mouth.
  • the cap wall Below of the rest area, the cap wall has at least three arranged around the circumference, approximately vertically running Zones of weakness where the strength of the Cap wall is reduced.
  • the Attenuation zones through an at least partial reduction the wall thickness, e.g. through vertical running notches, formed.
  • Tearing of the cap wall in the area of a weakening zone becomes particularly obvious because the cap wall in the Area of the weakened zone has a smooth outer surface. This can e.g. be achieved when the weakening zones by provided on the inner surface of the cap wall Depressions are formed.
  • the quality of the snap lock in terms of its Tightness is primarily due to the strength of the Depending on the inner surface of the cap wall protruding locking means. To maintain the original quality of the seal even when it is renewed Close the container after opening it for the first time to ensure the strength of the cap wall in the annular locking area are not affected. The vertical weakening zones are for this reason arranged below the rest area so that the strength the rest area is not affected even if the cap wall in the range of one or more Zones of weakness torn.
  • the snap lock for opening metal crown caps usual cap lifters used, the gripping tooth engages on one side on the cap wall.
  • the cap wall must be opened the first time Tear the snap lock in any case, regardless of which point on the circumference of the cap the Cap lifter is attached. To ensure this requires at least three vertically running weakening zones, which are arranged distributed over the circumference. Prefers however, there will be a larger number of weakening zones used.
  • the weakening zones are located thus in an area of the cap wall that does not pass through locking elements provided on the inner surface is reinforced. There these areas especially when opening the snap lock the cap wall will tear due to the weakening zones arranged in this area additionally favored.
  • Cap lifters of this type have a gripping tooth, the the lower edge of the cap wall at a point of the Extends underneath and one connected to the gripping tooth Support surface, which on the outside of the cap base is present and serves as an abutment.
  • the distance between that Gripping tooth and the support surface is with most cap lifters matched to the relatively flat metal crown caps and is usually about 12-15 mm.
  • the height of the cap is therefore in a preferred embodiment maximum 12 mm, so that the closure with a Cap lifter of the type mentioned can be opened.
  • the cap wall is preferably kept as small as possible designed their outer surface several over the circumference ribs arranged radially outwards having. Through these ribs, the axial load capacity the cap wall increased. Because that was caused by a cap lifter Load is greatest at the bottom of the cap, the ribs are preferably designed so that they are up to extend to the lower edge of the cap.
  • a second way to improve the axial load capacity the cap wall is the lower, with weakened zones provided area of the cap wall from two concentric To shape ring elements.
  • the cap wall is there thereby in their lower, with weakened zones Area from an inner support ring and a support ring surrounding, concentric to this arranged ring.
  • the approximately vertical weakening zones become provided on the outer guarantee ring. So that is achieved that when opening for the first time, it is primarily the outer guarantee ring is destroyed and the more stable support ring the vertical Absorbs lifting forces of the cap lifter.
  • the concentric Rings are therefore preferably designed so that only the outer guarantee ring has weakening zones, while the inner support ring is not weakened by weakening zones is and therefore has a much higher strength.
  • a snap fastener of this type is preferred designed that the guarantee ring extends over the bottom of the support ring extends downward.
  • the already principles explained above for the design of the weakening zones also apply in the event that this on a Guarantee ring of the type just described can be attached.
  • the weakening zone is also preferred here by an indentation provided on the inner surface of the guarantee ring formed, with the guarantee ring in the area of the weakening zones has a smooth outer surface. This has the advantage that the tearing from the outside is immediately recognizable.
  • the guarantee ring and the interior Support ring are the different functions of this Wall elements to be considered.
  • connection between the individual wall elements can be designed differently.
  • Wall elements are in this context three elements, namely the support ring, the guarantee ring surrounding the support ring and the upper part the cap wall, which in this context is also called a third ring element can be viewed and below is called a wall ring.
  • the support ring must be in the axial direction acting forces of the cap lifter on the upper wall ring (on which the snap elements of the snap lock are arranged) transferred.
  • the support ring is therefore preferred designed as a direct extension of the upper wall ring, so that the support ring together with the top wall ring forms a continuous wall section.
  • Light different diameters of support ring and wall ring are of course still possible, especially the outside diameter of the support ring compared to that of the wall ring preferably a little less space for the outside To create a guarantee ring.
  • the outer guarantee ring can be made in the same way as the Support ring also with the upper wall ring of the cap wall get connected.
  • the guarantee ring also only by a plurality of distributed over the circumference arranged, elastic webs with the rest of the cap wall get connected.
  • the “rest of the cap wall” is the Wall ring and the adjoining support ring meant.
  • the radial mobility becomes possible by the connection by means of webs of the guarantee ring further increased so that it the cap is opened for the first time is more easily pushed out and the vertical weakening zones thus tear faster.
  • the guarantor ring is joined by webs with the rest of the cap wall connected, these webs can also have a guarantee function take over:
  • the connecting webs are like this designed that when opening it for the first time, some of these Tear off the webs.
  • a Guarantee ring needed whose inner diameter is larger than is the maximum outside diameter of the rest of the cap wall.
  • the webs are preferred between the inner surface of the Guaranteed ring and the outer surface of the support ring arranged.
  • the force necessary to tear off the guarantee ring becomes determined by the number and thickness of the webs.
  • the weakening zones are preferably designed so that the Tear the cap wall in particular in the lower Area is clearly visible.
  • the weakening zone becomes like this designed that the outer surface of the cap wall a smooth Surface. There is a on the smooth outer surface Crack particularly easy to see.
  • the cap wall tears particularly slightly on if they are in the upper area of the weakened zone is broken, so that between the breakthroughs and the lower edge of the cap wall tearable web is located.
  • a simple variant for producing the above Snap lock is the whole Snap lock together with the vertically running weakening zones to cast in one operation.
  • the desired weakening zones can be an advantage be to attach the weakening zones later.
  • a closure is first used in a casting process a cap bottom, a cylindrical one adjoining it Cap wall and along the inner surface of the cap wall the circumferential locking means made. Subsequently are in a further operation in the lower area of the Cap wall at least three approximately vertically extending weakening zones appropriate.
  • the attachment of the weakening zones can e.g. with the help of a cutting tool by cutting or milling.
  • the attachment of the weakening zones can be done before or after putting on the cap on the container mouth.
  • An alternative method of making a Snap lock is first in a casting process made a cap, the cap wall several Has slits that extend vertically from their bottom edge extend upwards. These slots are made by deforming the cap wall and / or the filling of plastic material at least partially closed again, so that in the area the slits remain a zone of weakening of the cap wall.
  • the plastic material filled into the slots can e.g. a liquid or pasty adhesive act, which then dries and hardens. It can however, it is also a thermoplastic, filled in the slots when heated and solidifies again when it cools down. The renewed departure of the slots during the assembly of the snap lock can be prevented in this embodiment by that the slots only after the snap lock assembly getting closed.
  • FIG. 1 shows a snap closure according to the invention from below, with a view of the inner surface of the cap base 1.
  • An the inner surface of the cap wall 2 are distributed over the circumference a plurality of locking elements 3 arranged, which when attached Snap lock a bead on the container mouth reach behind.
  • the vertical weakening zones 4 are by notches 13 on the inner surface of the cap wall 2 formed, which in the space between successive Locking elements 3 are arranged.
  • Figure 2 shows a sectional view of the snap lock 1, the section plane runs along the in Figure 1 drawn level A-A.

  • Figure 3 shows the sectional view of a container mouth with attached snap lock. Reach behind the locking elements 3 a bead 5 of the container mouth.
  • the ring-shaped Locking area 6, in which the radial thickness of the locking elements 3 their maximum reaches 7 is for the fastening of the cap on the container mouth particularly important.
  • a weakening of the cap wall 2 in the area of the annular Rest area 6 would be the quality of the seal that can be achieved greatly decrease.
  • the weakened zones formed by notches 13 4 are therefore below the annular locking area 6 of the cap wall 2 arranged.
  • a cap lifter 10 is also shown in FIG a position like that to open the container on the snap lock is scheduled.
  • the gripper tooth 9 of the cap lifter grips under the lower edge of the cap at one point.

  • Figure 6 shows the side view of an alternative embodiment a snap lock where the cap wall is broken in the upper area of the weakened zones. There is one below each of the breakthrough points 15 tearable web 16.
  • This variant has the advantage that the part of the cap wall to be torn open on the web 16 and thus concentrated on the lower edge area of the cap wall is. Since the load occurring when opening the lower Is greatest at the edge of the cap wall, the webs 16 tear particularly quickly. This could be a further improvement achieved that the radial thickness of the webs 16 is reduced. This is benefited by an additional one Notch on the inner surface of the cap wall reached, so that the cap wall in the area of the web 16 is still has a smooth outer surface.
