Definitions

  • the present invention concerns a closure, seal or cap for a container containing a fluid.
  • the closure comprises a body to be placed on the container with an outlet opening via which the fluid is discharged when a container-internal excess pressure is generated. It is known, for generating the container-internal excess pressure, to construct the deformable container such that in the case of manual pressure on the walls of the container, the internal volume of the container is reduced and the desired internal pressure of the container can be generated.
  • the fluid can then exit via a slotted structure constructed in the body, which comprises at least one slot.
  • the at least one slot is defined by a pair of free terminal edges facing each other and ending in a common apex.
  • a closure of this type with a plurality of slots is known from the document WO82/01360, in which terminal edges of triangular pivoting plates are essentially adjacent in an activation state free of container-internal excess pressure and define an opening plane.
  • the terminal edges are opened by pivoting, moving away from the interior of the container, by the fluid, moving away from each other.
  • the aim of the invention is to overcome the disadvantages of the prior art, in particular to create a closure having a slotted structure with at least one slot which is defined by free terminal edges facing each other, with which a sufficient making tight is likewise guaranteed in an activation state free of container-internal excess pressure and a resistance to discharge flow is increased.
  • a closure which comprises a body with an outlet opening via which the fluid can be discharged on the generation of a container-internal excess pressure and which is defined by a slotted structure having at least one slot, which is bounded by free terminal edges facing each other and ending in an apex.
  • the slotted structure comprises multiple pivoting plates which are articulated to the body so as to be moveable, at least one pivoting plate, preferably each of the pivoting plates, being connected to an adjacent pivoting plate so as to be moveable, via a deformation section that is more flexible relative to the multiple pivoting plates, which forms one of the free terminal edges of the at least one slot, and in an activation state free of a container-internal excess pressure is arranged essentially adjacent to the other opposite free terminal edge of the at least one slot and can open by pivoting, moving away from the container interior when the container-internal excess pressure is generated by means of the fluid, thus moving away from the other free terminal edge.
  • the multiple pivoting plates are connected via a hinge-joint, in particular a film hinge-joint, to the body in such a way that, when the container-internal excess pressure is applied by means of the fluid, they pivot, moving away, and deform the deformation section in such a manner that the terminal edge thereof moves away from the other terminal edge, moving apart from each other.
  • a hinge-joint in particular a film hinge-joint
  • the two free terminal edges of the at least one slot are formed by two deformation sections which connect one pivoting plate to the two adjacent pivoting plates. In an activation state free of container-internal excess pressure, the two free terminal edges are parallel side by side.
  • the terminal edges of the at least one slot are preferably essentially in the form of a straight line.
  • slots are provided for the slotted structure, these preferably terminate in a common point, in particular in an axial outlet opening center.
  • the multiple pivoting plates form primary and secondary pivoting plates, the primary pivoting plates lying in a common plane, and the secondary pivoting plates intersecting this plane at an angle, preferably of 20° to 70° or 30° to 60° in an activation state free of container-internal excess pressure.
  • the primary pivoting plates of the multiple pivoting plates lie in a common plane which intersects the deformation sections at an angle, preferably of approximately 20° to 70° or 30° to 60°.
  • primary pivoting plates of the multiple pivoting plates lie in a common plane which intersects the free terminal edges at an angle, preferably of approximately 20° to 70° or 30° to 60°, in particular in a center of the outlet opening.
  • the primary pivoting plates can be inclined relative to each other.
  • a pivoting plate in particular a secondary pivoting plate, and with the latter deformation sections adjacent thereto, form a pyramid, one long edge of which is slotted by the free terminal edges of the deformation section.
  • the slotted long edge can be directed towards a center of the outlet opening.
  • at least two of the three long sides of the pyramid shape have equal area.
  • the slotted structure can be formed by at least two, preferably two, three or four pyramid shapes which are in particular respectively formed by one secondary pivoting plate and by the adjacent deformation sections, one primary pivoting plate lying between two pyramid shapes.
  • a base side of the pyramid shape lies in a plane which is defined by primary pivoting plates of the multiple pivoting plates in the activation state free of container-internal excess pressure.
  • the secondary pivoting plates can be thick like the principal pivoting plates, but thin at the level of the hinges.
  • the pivoting plates in particular the primary and secondary pivoting plates, are dimensioned with thicker walls than the deformation section, which is constructed for example as a connection attachment in the form of a film or membrane which is able to be flattened or to be bent.
  • the pivoting plates, in particular the primary and secondary plates, and also the deformation sections are produced from one piece, in particular by injection moulding.
  • the pivoting plates are preferably connected to the body via a hinge-joint, in particular a film hinge-joint, with the hinge-joints extending in particular in an annular form around a center of the opening.
  • the closure consists of two separate pieces, namely a base body to be connected to the container and an insert forming the slotted structure.
  • the insert is mounted on a passage formed in the base body.
  • the two pieces are produced by an injection moulding of two components of plastic material.
  • the invention likewise concerns a container with a closure according to the invention.
  • the closure can be fixed on the container, in particular screwed.
  • the closure and the container are preferably produced from one piece, in particular by injection moulding.

  • FIG. 14 shows a perspective view of an insert forming the slotted structure.
  • the closure 1 comprises, as main element, a support body 3 which can be fixed on a container which is not shown.
  • the support body 3 is in the form of an upturned cup with an oval lateral wall 5 over its entire periphery, which changes to horizontal base edge 7 .
  • a passage 11 bounded by an axial projecting centering ring 9 , is formed in the edge base 7 .
  • a cover 13 is articulated via a film hinge 15 .
  • the cover 13 comprises on the internal face a cylindrical projection in the form of a socket 17 which is in internal contact with the centering ring 9 and ensures tightness in the closed state of the cover 13 .
  • a slotted structure 12 in the passage 11 of the support body 3 is constructed in the embodiment of the closure 1 according to the invention shown in FIGS. 1 to 4 by means of two pyramids 20 , 22 which exceed a horizontal plane E.
  • the vertical of the plane E extends on the axis A of the seal 1 .
  • the two pyramids 20 , 22 are arranged symmetrically relative to the axis, relative to each other, and comprise respectively a secondary triangular pivoting plate 29 , 31 connected via a film hinge joint 33 , 35 to the adjacent support rib 21 , 25 .
  • the film hinge 33 , 35 is arranged on the base face of the triangular shape of the same side of the secondary pivoting plates 31 , 29 .
  • the film wings 37 , 39 , 41 , 43 respectively have a free terminal edge in the form of a straight line.
  • the free terminal edges of the adjacent deformation sections 41 , 43 essentially face each other in a parallel manner—in an activation state free of container-internal excess pressure—and form slots ( 45 , 47 ) which are sketched with lines in bold print in FIGS. 1 and 2 .
  • the terminal edges end in the point of the respective triangular secondary pivoting plate 29 , 31 , where they define an apex.
  • the film wings respectively 37 , 41 and 39 , 43 end respectively with an adjacent primary pivoting plate 51 , 53 , constructed thicker than the film wings 37 to 43 and, essentially, as thick as the secondary pivoting plate 29 , 31 .
  • the primary pivoting plate 51 , 53 has the form of an isosceles triangle, its base face being articulated by means of a film-hinge articulation to the adjacent support rib 23 , 27 of the support body 3 .
  • FIGS. 1 to 4 the closure 1 is shown in an activation state free of container-internal excess pressure, because the free terminal edges of the slots 45 , 47 of the deformation sections 37 to 43 are placed parallel side by side with respect to each other, preventing at the maximum an outlet through the two slots defined by the terminal edges.
  • the fluid flows from the interior towards the primary pivoting plates 51 , 53 and the secondary pivoting plates 29 , 31 of the slotted structure 12 and causes them to pivot upwards, moving them away from the interior of the container. Due to the pivoting of the primary and secondary pivoting plates 51 , 53 , 29 , 31 , the terminal edges of the respective deformation sections 37 to 43 are moved apart from each other, essentially by diverging around the apex at the point of the secondary pivoting plate 29 , 31 , by which an outlet opening gradually grows larger from a center Z in the form of a point around the axis A, so as to form a square according to the embodiment in accordance with FIGS. 1 to 4 .
