Definitions

  • the invention relates to a closure for containers for receiving flowable contents with the features of the preamble of claim 1.
  • cap-like closures with a pivotable pouring spout are known in various embodiments. It is expedient for the closure to be in one piece with all its parts, e.g. manufactured by injection molding. The production takes place in the pouring position of the spout, as a result of which considerable spring forces are stored in the pivoted closure position of the spout, which endeavors to move the closure spout back into the open position. However, in order to act reliably as a closure, the pouring spout must be locked sufficiently firmly in the closed position against these forces acting in the opening direction.
  • the spout can be locked over a noticeable part of its length and on its two longitudinal sides at the same time snap-fast and thus sufficiently firmly on the closure cap body when the spout is pivoted into the closed position.
  • the locking projections arranged on the cap body are arranged on a rigid wall section of the cap body which is approximately parallel to the cap base, but is recessed relative to the latter, so that they have a stable design and can project inwards over a sufficient locking effective length.
  • This wall carrying the locking projections can at the same time advantageously as one
  • a connecting wall between the peripheral wall of the cap and a concentric inner sleeve can be formed, which extends inwards from the cap bottom and on which the edge of the membrane-like flexible wall section can be fixed in one piece.
  • this facilitates the production and, on the other hand, a sufficiently large expansion of the membrane-like flexible wall section over the length of the sleeve, to ensure a slight snapping of this wall section when the pouring spout is pivoted between its two positions, and at the same time to avoid excessive tensions in this wall section or premature material fatigue.
  • the closure 1 has a cylindrical closure cap body 2 with a flat cap base 3.
  • the wall thickness of the cap body is chosen so that it is relatively rigid.
  • the cap body has an approximately rectangular recess 22 which is closed at the bottom by a wall 30 approximately parallel to the cap base 3 and to the circumference by a wall 19 running along a chord of the cap outline. At the location of the wall 19, the cap body is withdrawn to form a recessed grip for opening the closure.
  • a parallel straight wall 16 projects downward from the cap base 3.
  • the two walls 16 and 19 are at a mutual distance which is equal to or slightly larger than the radius of the cap body 2.
  • an inner sleeve 8, which projects inwards from the cap bottom 3, is provided concentrically with the outer wall 2 of the cap body is connected to the peripheral wall 2 of the cap body in the region of the recess 22 via the wall 30.
  • a lid 10 is hinged to the cap base 3 in one piece, which is shown in the open position in FIG. 1 and which in the closed position according to FIG. 2, the recess 22 of the cap covering upwards.
  • the lid 10 has a free end 11 which, in the closed position according to FIG. 2, projects beyond the recessed grip on the outer circumference of the cap and can thus be gripped easily with the fingers.
  • An elongated pouring spout 14 is integrally formed on the circumferential side of the cover 10, the pouring end 18 of which, after pivoting in accordance with the arrow 17, cooperates with the wall 19 in the closed position, while its inner end has an integrally formed sealing sleeve 15 which, in the closed position, is biased against the wall 16 lays so that in the closed position both ends of the pouring spout 14 are at least covered and the inner end is sealed at the same time.
  • the pouring spout 14 is connected to the cap base 3 in a sealing and articulated manner via the cover part 10. Otherwise, the inner end of the pouring spout 14 is sealingly but movably connected to the cap body by means of a flexibly bendable membrane 4. This is formed in one piece with the cap parts and of comparatively small thickness compared to the other parts. In the plane of the cap base 3, the membrane is firmly connected to the lower end of the pouring spout 14, as indicated at 13.
  • the flexible wall section 4 is fixedly connected to the inner surface of the sleeve 8 along a plane which is indicated at 5. The central region of the flexible wall section 4 is convexly curved outwards in the open position shown in FIG. 1, as indicated by the thick line 6.
  • the wall section 4 jumps over and reaches the concave, inwardly curved position 6a, as shown in dashed lines in FIG. 1, in dashed lines. Overstressing of the flexible wall section is avoided by its relatively large surface area, which is achieved in that the sleeve 8 jumps far into the interior of the cap and the flexible wall section 4 extends to the lower end of the sleeve 8.
  • the pouring spout 14 which can be of any cross-section, it has elongated locking sections on its sides.
  • these are elongated Strips 20, 27 are provided which extend along diametrically opposed surface lines of the pouring spout 14.
  • Each web has a locking surface 20 lying in the diametrical plane in the closed position and an inclined ramp surface 27 pointing downward.
  • webs 21 to 24 projecting upward from the intermediate wall 30 are provided at a corresponding distance at a mutual spacing of the surfaces 20. These protrude from the wall 30 upwards towards the cap base 3. At their upper free edges they point towards the pouring spout 14 inwardly projecting bends or ridges 23, 25 which are arranged so that they are in the closed position the surfaces 20 reach behind. As a result, the pouring spout is locked in the closed position, which ensures that this closed position is maintained even against considerable elastic restoring forces or against mechanical effects on the handle portion 11 of the lid. The locking engagement extends over a considerable length of the closure sleeve 14, which promotes a secure hold.
