Definitions

  • the invention relates to a one-piece snap lock made of plastic according to the preamble of patent claim 1.
  • a snap lock of this type is known from US-A-4 124 151.
  • This snap closure has spherical cap-shaped pivot pins and correspondingly shaped recesses in the side walls of the recess of the closure provided for the cover. With this closure it is provided that the closure spring construction is not kept under noticeable tension when the cover is in either the open or the closed position, so that this construction ensures a permanent, flawless closed position of the cover under the action of pressure over a long period of time is not guaranteed.
  • the invention has for its object to improve this known snap closure so that it can be better adapted to the manufacturing or casting tolerances, so that such a construction generally ensures that the closure within these tolerances neither in the fully open nor in the fully closed position of the lid is subject to noticeable stresses.
  • the snap lock should be compact with the least possible amount of material with a relatively simple tool design and with easy disassembly of the pivot bearing construction for cleaning purposes of the lock, optimum stability of the entire construction should be achieved while avoiding deformation of the bearing points when the snap lock is actuated.
  • a one-piece snap closure made of plastic with a lower closure part 1 is shown, which can be fitted tightly on the neck surrounding the opening of a container, not shown, by means of a part 12 projecting from the underside of a cover plate 11.
  • An opening 13 through the cover plate 11 can be closed by means of a stopper 14 which is arranged on the underside of a sealing lever 3 which is pivotably mounted relative to the lower closure part 1.
  • the sealing lever 3 is connected at a distance above the cover plate 11 to the lower closure part 1 by a spring hinge 2 and can be pivoted between an open and closed position while overcoming a dead center position 9.
  • the bearings 18 for the guide rollers 7 consist of upwardly open insertion openings 19 in support walls 20 which are arranged on the cover plate 11 of the lower closure part 1. These insertion openings 19 limit the diametrical incision 21 in the closure top 6 for the sealing lever 3 and the spring hinge 2 on both sides of the incision 21.
  • the bearing surface 22 of the pivot bearings 18 for the guide rollers 7 are each semicircular deepened and provided in support walls 23 which are provided transversely to the incision 21 on both sides thereof and the pivot connection 16 between the lower closure part 1 and spring hinge 2 are facing. These support walls 23 form an extension of the incision 21 in the region of the guide rollers 7.
  • the sealing lever 3 is essentially rectangular and together with the spring hinge 2 in the diametrical incision 21 in the closure top 6 together with the guide rollers 7 between the essentially parallel, the incision 21 and the guide rollers 7 delimiting support walls 22, 23 retractable.
  • the length of the sealing lever 3 is larger than the length of the spring hinge 2.
  • the pivot connection between the spring hinge 2 and the lower closure part 1 is narrower than that with the guide rollers 7, as can be seen from FIG. 2.
  • the snap lock is provided in one piece in plastic by injection molding for flexible or non-deformable containers.
  • the lower closure part 1 can be screwed or shrunk onto the container in such a way that the plug 12 designed as a sealing cone seals the container.
  • the assembly or the completion of the lower closure part 1 and sealing lever 3 are thus already carried out in the tool.
  • the spring hinge 2 with a molded-on sealing lever, in connection with the swivel connection forming a film gate, is folded over and sunk into the cap surface or top side 6 of the closure, as shown in FIG. 3, an area-like closure being formed on the top side 6 of the closure.
  • 4 shows the kinematic rotation sequence of the two guide rollers 7 with an eccentric connection of the spring hinge 2.
  • the spring hinge 2 In the closed position of the sealing lever 3, the spring hinge 2 is unstressed, the lateral guide rollers 7 in the pivot bearings 18 ensuring parallel guidance of the sealing lever 3.
  • the spring hinge 2 bulges outwards in the direction of arrow x, because the tangential articulation point of the pivot connection 15 between spring hinge 2 and sealing lever 3 in FIG. 4 in the clockwise direction is rotated on a swivel circle so that the distance between the joints of the two swivel connections 15 and 16 is reduced and the spring hinge is tensioned.
