Definitions

  • Plastic snap hinges can be roughly classified into two types, namely those in which the snap action is achieved by a tension element or those in which this is done by a resilient bending element.
  • the present invention relates to a plastic snap hinge of the second type.
  • resilient bending elements which have a U-shaped or L-shaped shape.
  • the dimensioning of the bending elements is essentially dependent on the spring travel and the spring force that are desired.
  • closures with a relatively large pouring opening and a relatively flat lid do not use the known bending elements.
  • the leg extending into the cover surface of the cap cannot be made long enough, because otherwise it would reach into the sealing area of the pouring opening.
  • U-shaped bending element this cannot be made large enough because the small cap height does not offer enough space to accommodate the bending element.
  • the object of the present invention is to create a bending element which offers a solution for the above-mentioned applications.
  • FIGS. 1-5 show a plastic closure which is suitable for a plastic container 30 which only has a small outlet opening 31.
  • Such containers are used in particular for cosmetics that are applied directly to the skin, such as sun creams or body lotions. This means that the Cap 2 of the closure can be pivoted open at least approximately 180 ° with respect to its closed position.
  • the closure consists of a lower part 1 and a cap 2 which are pivotally connected to one another via two film hinges 3 arranged on a straight line. Between the two film hinges 3 there is a bending element 4 which generates the spring force required for the snap action.
  • the lower part 1 consists only of an annular, vertical side wall 10, which has only a tapered collar 11. Even in the closed state, a gap 12 remains between the cap 2 and the lower part 1. This is necessary in order to be able to inject the closure in the closed state.
  • the collar 11 of the lower part 1 is pulled down, so as to form a recessed grip 13, which allows the cap 2 to be pushed upwards from below with the thumb, up to the unstable equilibrium position, whereupon the cap in the fully open position, as shown in Figure 4, snaps.
  • the sealing of the cap 2 with the pouring opening 31 of the container 30 takes place by means of a sealing pin 21 molded onto the underside of the cover surface 20.
  • This can be provided with one or more circular sealing rings 22 in order to increase the sealing and in particular the locking force.
  • the cover surface 20 is shaped concavely from above for optical reasons, but also to increase the rigidity.
  • a plurality of support cams 23 can be attached to the underside of the cover surface 20. These are in the assembled state 1 of the closure and the closed position of the cap 2 on the container 30.
  • the bending element 4 can also be removed from the mold when the closure is closed. In cross-section it has the shape of a U and an adjoining L. standing upside down. The recess 40 of the U-shaped part runs exactly in the direction of extension of the tool.
  • the bending element 4 is connected to the cap 2 or the lower part 1 via two joints 41 and 42.
  • the hinge 41 which forms the connection between the side wall 10 and the bending element 4, lies approximately at the height of the upper edge of the container 30 on which the closure is mounted.
  • the hinge 42 connects the cap 2 to the bending element 4.
  • the two joints 41 and 42 are each equidistant from the fixed film hinge 3.
  • the minimum distance between the two joints 41 and 42 is a ⁇ ⁇ 2 if the distance from each joint 41, 42 to the film hinge 3 is equal to a.
  • the maximum distance between the two joints 41 and 41 is reached and is exactly 2 ⁇ a. This is the case when both joints 41, 42 are vertically one above the other.
  • FIGS. 6 and 7 show a further embodiment of the invention using a second closure.
  • This closure has essentially the same features as the closure previously described and shown in FIGS. 1 to 5.
  • This closure is suitable for a container 30 '(only dotted) with a further container neck 32.
  • the lower part 1 must be designed so that it can grip around the container neck 32.
  • the side wall 10 'of the lower part 1 which bears against the container 30' is provided with a cover surface 14 which has a vertically downwardly directed annular wall 15 which seals the container neck 32 of the container 30 ' embraces.
  • a spout 16 is formed in the top surface 14 of the lower part 1 within the area delimited by the annular wall 15.
