Definitions

  • the present invention relates to a plastic closure for solid or deformable containers, which closure is an integral part of the container or can be placed thereon, with a lower part and a cap or a cover which is integrally connected to the lower part via at least one tensioning strap.
  • the object of the invention is to provide a closure of the type described at the outset which eliminates the disadvantages mentioned.
  • the resulting force of the tensioning straps acts as the closing force of the closure, even when the closure is closed.
  • the strap level can run parallel to a perpendicular to the parting plane between the lower part and the cap. This has the effect that the resulting force in the closed position is also introduced vertically onto the parting plane.
  • the closure according to the invention always consists of a lower part 1 and a cap or lid 2.
  • the lower part 1 is placed on a solid or deformable container, not shown in the drawing, or represents the lower part of the container itself.
  • FIGS. 1 -5 and 8a to d closures for attachment to solid or deformable containers are shown.
  • the lower part 1 and the cap 2 are in direct contact with one another.
  • the contact surface lies in the so-called parting plane, which is designated T in the drawing.
  • the lower part 1 and the cap or lid 2 are integrally connected to one another via at least one tension band 3.
  • the tensioning straps 3 are from the lower part 1 or from the cap 2 via sprues 4 slightly distant.
  • the straps 3 run in a plane E.
  • the plane E intersects the closure parallel to its axis of rotation a.
  • the lower part 1 and the cap 2 are connected to one another via a film hinge 5.
  • the pivot axis of the film hinge 5 is on the one hand in the parting plane T and on the other hand parallel to the plane E in which the tensioning straps 3 are located.
  • the tensioning straps 3 are tensioned, as a result of which there is a resultant force which lies within the outline of the closure of plane E and maintains a closing pressure between the lower part 1 and the cap 2. If the closure is intended for use on a container with a gas content, the closing pressure should be as large as possible.
  • variable sizes in their dimensioning are the width and the thickness of the tensioning straps 3 and the distance of the plane E in which the tensioning straps 3 lie to the axis of rotation a of the closure.
  • closure according to the invention can be combined with any type of known locking element, for example also with a childproof locking element.
  • closure according to the invention can be attached to any design of the lower part and the cap if appropriately adapted.
  • Figures 3 and 4 show a lower part 1 and a congruent cap 2 with a twelve-sided plan.
  • the hinge 5 should run approximately in the parallel side surface 6 closest to the plane E.
  • the plane E in which the tensioning straps 3 lie, runs parallel to a vertical to the parting plane T, which in the present case is identical to the axis of rotation a.
  • the straps 3 run in a plane E, which in turn cuts the closure, but this time the plane E is inclined to the vertical v to the parting plane T.
  • the sprues 4 are also arranged asymmetrically to the parting plane T, in contrast to the examples described above.
  • the inclined straps 3 cause two things.
  • the position of the maximum expansion of the tensioning straps 3 can be shifted accordingly. From the position of maximum expansion 3, the cap folds in the direction of the closed or open position.
  • the desired opening position of the cap 2, in which the tensioning straps 3 are relaxed, can be desired differently depending on the type of closure, the shape of the spout or the type of container to be closed.
  • FIG. 6 shows a can which is designed with the closure according to the invention.
  • the can and thus also the lower part 1 and the cap 2 have an approximately rectangular plan.
  • the lower part 1 and cap 2 are connected to one another here via three tensioning straps 3 arranged on the same side surface.
  • the closure can of course also be formed from a single, somewhat wider tightening strap.
  • the tensioning straps 3 are arranged inclined to a vertical v on the parting plane T.
  • the straps 3 are in niche-like recesses 7 which are inclined to the longitudinal side 8 of the can.
  • FIG. 7 shows a section along line A-A according to FIG. 6.
  • the conditions in the area of the niche-like recess 7 are illustrated in detail in FIG. 7a.
  • the arrangement of tensioning straps 3 in niche-like recesses 7 can of course also be realized with other forms of closure, such as those in the figures described above.
  • the arrangement of the straps 3 in niche-like recesses 7 has the advantage that no parts of the closure protrude beyond the contour of the lower part or the cap. This is particularly advantageous if the closure is mechanically placed on a container, since the closure then no longer has to be aligned with a gripper, in accordance with the above parts.
  • FIGs 8a - a hinge-less closure is shown in different openings. Again, this is a closure with a cylindrical lower part 1 and cover 2 with the same cover.
  • the sprues 4 for the tensioning straps 3 are in turn asymmetrical to the parting plane T. Of course, the level E in which the tensioning straps 3 lie also intersects the closure here.
  • the special feature of the present closure is that it has no hinge, so that the cap 2 and the lower part 1 only on the instep bands 3 are interconnected.
  • the closing forces which are exerted by the tensioning straps 3 behave in the same way as in the variants described above.
  • the closing force lies within the plane E and is represented by an arrow F indices I.
  • Figure 8b shows the same closure in a slightly open intermediate position.
  • the tensioning straps 3 are now somewhat more stretched and now produce a somewhat increased resulting force F 2.
  • the resulting force F 2 still runs in the plane of the tensioning straps, which is however now inclined in accordance with the degree of opening of the cap 2. Consequently, the resulting force F 2 can be broken down into a component FS, which tends to close the cap 2, and into a component FZ, which tends to pull the cap 2 towards the center or the axis of rotation a.
  • the lower part 1 has a structure 9 which is offset inward about the wall thickness of the cap 2 concentrically with the axis of rotation a.
  • the structure 9 runs conically to a central pouring opening 10.
  • the fictitious axis of rotation is parallel to plane E and runs exactly through the point of contact between cap 2 and lower part 1.
  • the component FS decreases and the component FZ increases accordingly. This continues until the force component FZ overcomes the static friction between the lower part 1 and the cap 2, whereupon the cap 2 abruptly abuts against the set-back structure 9.
  • the cap 2 is completely opened, as shown in FIG. 8c, and the tensioning straps 3 relax largely, but not completely, so that a small resulting force remains which holds the cap 2 in the open position according to FIG. 8c. If the structure 9 has only a low overall height, as shown in FIG. 8c, the tensioning straps 3 could pull the cap 2 onto the structure 9 and thus make it much more difficult to close the cap 2 again.
  • a stop 11 is molded onto the structure 9, which is located in the area between the two sprues 2 of the lower part 1.
  • the sequence of movements when opening and in particular when closing the closure is optimized in that the transition 12 from the lower part 1 to the structure 9 is rounded. If the structure 9 is relatively low, as shown in FIG. 8c, the rounded transition 12 can run directly from the parting plane T to the stop 11.
  • the parting plane T here is also the parting plane of the injection mold.
  • the tensioning straps 3 are injection molded so that they have a greater length than the distance between the two corresponding sprues 4, which corresponds to the injection mold.
  • the hinge-free design is of course not only possible with rounded closures, but in principle with any design of the closure. In the embodiment according to FIGS. 6 and 7, one would then only have to speak of a line of contact instead of a point of contact. If the closure has an odd number of tensioning straps, as can be seen in FIG. 6, then if the structure 9 is too low, an even number of stops 11 would have to be provided. In the case of a can, the structure 9 would, for example, only correspond to an inwardly offset edge. As is known from many boxes.
