  • the invention relates to a screw cap made of metal for closing containers, which are provided for this purpose with a thread at the opening, with a bead or curl at the lower edge or a lower annular bead, which is spaced from the lower edge inserted inside the shell wall and from the Surface projecting bead-shaped.
  • Screw caps of the generic type are used to airtight containers, such as tubes, canned and beverage bottles and other bottles, which are provided for this purpose with a thread on the opening or an opening neck.
  • Metal screw caps are made without thread. During the closing process, they are first pressed from above against the sealing surface, after which the thread is rolled on the side, with a quasi-copy of the thread being formed from the container neck of the opening into the cap.
  • the caps used for beverage bottles are usually made of aluminum sheet and those for glasses made of tinplate.
  • a tamper-evident ring is attached to the lower edge via connecting webs. This tamper-evident ring engages under a retaining ring on the neck of the beverage bottle opening.
  • the cap can be turned with one hand via a ribbed upper edge of the cap and / or a corrugation on the outside of the tamper evident ring.
  • a screw cap made of metal for closing containers with opening threads with a beading at the bottom known, wherein in the inside of the shell wall spaced an annular bead and is parallel to the beading incorporated so that an annular bead protrudes wave-shaped, with the beading a V forms a shaped annular channel.
  • the threaded zone of the screw cap is provided above the annular bead.
  • a plastic sealing element is provided with a formed over a weakening zone originality ring below the V-shaped annular channel, which engages under the retaining ring and tears off when opening the closure and remains on the container.
  • a metal screw cap with tamper evident ring is known which engages under a retaining ring on the outside of a container mouth or opening neck.
  • the retaining ring is made of plastic, preferably a polyolefin or the like., And is attached to the lower edge of the screw cap.
  • the retaining ring is held by clamping action due to its elasticity on the screw, in particular snapped or locked and for this purpose has on its inside a circumferential groove which engages over a bead or curl at the bottom of the screw.
  • the lower edge of the screw cap can be embedded in the securing ring during its production, in particular cast or injected.
  • the securing ring consists of an annular body fastened to the screw cap and an annular bead engaging the retaining ring of the container mouth, in particular engaging under its retaining ring.
  • Both parts are connected by webs or a weakening point, which has a circumferential uninterrupted material weakening or webs, which shear off when turning the screw, so that the annular bead remains at the opening neck of the container while the ring body remains on the screw cap.
  • a plastic locking ring for a metallic screw cap for containers that has an upper ring anchorable by means of a projection to a bead provided at the lower edge of the cap, and a tearing over a first opening of the closure Having predetermined breaking line and holding webs with this associated lower ring, which engages under the thread provided under the container retaining ring.
  • the wall of the lower ring part is provided with several, vertical predetermined breaking points having weakening zones.
  • the holding webs are arranged in the middle between two adjacent weakening zones.
  • the strength of the retaining webs is chosen so that they hold after the first opening of the SSverBankkappe separated at the predetermined breaking lines segments of the lower ring member, whereby the segments remain in a relation to their original position outwardly entangled position.
  • the wall thickness of the lower ring part is reduced in the area of the holding webs.
  • At least one annular bead is spaced apart and parallel to the bead, the curl or the lower annular bead in such a way that projects from the outside of the shell wall, an annular bead wavy, at least with the flanging in the inside of the jacket wall of the screw cap , the Einrollung or the lower annular bead forms a U-shaped annular channel, wherein above the annular bead, the threaded zone of the screw cap is provided.
  • At least one protruding annular bead is thus additionally attached, which enables an extended use of the screw cap.
  • This at least one additional ring can be embossed with a corrugation, so that the cap when unscrewing with the thumb and another finger of a hand can be detected over a large area, whereby a higher force transmission surface or friction surface is given to apply the necessary torque, the to loosen a relatively tight fitting cap when unscrewing is required.
  • a further bead can be incorporated, so that a third bead-shaped ring is formed, which can be used in the same way.
  • the ring formation significantly strengthens the screw cap, so that very thin sheet metal can be used for the production.
  • the additional annular bead prevents retraction of the shell wall when rolling the screw.
  • the reinforcing effect is also advantageous if a fixing ring of a tamper-evident ring or another marking ring is engaged in the annular channel. This engages relatively large area in the annular channel and is stored secured in both directions against thrust and train, so it requires no further fixing training.
  • a large bearing surface is provided, which can be increased by intermeshing paired patterns, whereby a very high relative security against twisting is given and over the outer surface of this ring, a relatively high areal torque transmission is also ensured on the cap.
  • this surface of the parts can of course also be smooth, which is advantageous if a ring from below on the flanging, Rolled or rolled the annular bead of a lower annular bead and engages in the annular flange.
  • the surface of the annular flange can also be used as a grip surface. For this purpose, it may be roughened, knurled or embossed embossed.
  • the height of the annular channel at least to the width of the bead or the width of the flange or of the curl such that an inserted ring or fixing ring has a visible conspicuous width.
  • the above bead, the curl or the bead of the lower annular bead on the outside can protrude from the lateral surface by a height which is equal to the height of the protruding bead of parallel at least one upper annular bead or deviates therefrom and thereby defines the depth of the annular channel.
  • the annular channel can be used for marking and can be printed, for example, with defined colors and contents. If a ring is to be inserted into the annular channel, it is expedient to produce it in such a shape-adapted from plastic, that it can engage by utilizing the inherent elasticity. If the ring is a tamper-evident ring, it should be locked in place before pressing the screw cap on the opening neck of the container, the fixing ring in the annular channel and thus connected via webs retaining ring a retaining ring on the outside of the opening neck with molded trigger fins or a trigger safety ring with an inward engage under the protruding edge, wherein the locking ring is disengageable when unscrewing the screw cap by turning.
  • a weakening zone can be provided with segment cutouts on the retaining ring, which tear when unscrewing the cap and the segments to the outside release swiveling.
  • a retaining ring in the wall of the opening neck and a groove be introduced annular, which has a stepped annular flange, which is engaged behind the trigger safety ribs or a trigger safety ring. If the retaining ring on the cap remains in the unscrewed state, the cap can be disposed of with the retaining ring.
  • the connecting webs are formed as partitions or correspondingly formed weakening zones between the fixing ring and the retaining ring provided that shear off when turning the cap.
  • the screw cap can also directly in extension at the bottom below the annular channel have a circumferentially extending perforation and a circlip with these introduced in the longitudinal direction incisions or predetermined breaking points forming weakening, which circlip is drawn to the lower wall portion around a crimping edge and at the bottom of the retaining ring and / or rests against the opening neck of the container.
  • a circlip is z. B. from the DE 20 2004 016 649 U1 known and connected via connecting webs with the jacket wall of the cap, that the retaining ring segments, which are connected to each other via weakening zones and / or separating cuts, expose when unscrewing the cap to the outside.
  • Other versions are also possible.
  • the surface of the annular channel may have a specific embossing pattern and the inside of the ring or fixing ring may be provided with a corresponding surface which engages in the embossing pattern of the ring or fixing ring.
  • the incorporated bead can have a round or a trapezoidal cross-sectional profile and the bead or the curl can be annular and have a rounded or trapezoidal surface.
  • penetrations or beads projecting from the inner surface of the jacket wall can be incorporated into the jacket wall of the annular channel, and into the contour-adapted locking projections projecting on the inside on the ring or the fixing ring.
  • the invention also includes such embodiments in which the ring or the tamper-evident ring is not designed as a snap-on ring, but is injection molded onto the screw cap in an injection mold.
  • the locking lugs can also be mounted in the two-component injection process on the ring or fixing ring and stand out in color.
  • Fig. 1 is a first embodiment of a screw cap 1 shown in metal, which is sealingly als impliedd as a cylindrical hollow body on a bottle neck of a bottle or on the opening neck on another container and is deformed by pressing the shell wall 2 provided on the bottle or opening neck external thread, when the bottle or container is filled.
