Definitions

  • the invention relates to a machine into the mouth opening of closable, bottle-like containers, insertable pourer made of plastic, with a sealing flange at least partially covering the edge of the mouth opening and a hollow cylinder-like wall part which bears against the inner wall of the mouth opening.
  • Bottles are also known whose mouth opening is larger in the upper area than in a lower area facing the bottle interior. Again, it is difficult to anchor the pourer or insert in the mouth opening with sufficient holding force.
  • the invention is based on the object of designing a pourer of the type described at the outset in such a way that a secure anchoring of the pourer in the mouth opening is achieved even within a relatively large tolerance range without having to use a greater closing force than that required to apply the closure cap itself is required. Furthermore, the pourer should be designed in such a way that it can also be used in conjunction with other metering devices and can be easily produced in large quantities.
  • This object is essentially achieved by the invention in a pourer of the type described at the outset by providing at least two radially extending, elastic holding struts and an inner cylinder part, along which the radially extending holding struts extend over part of their axial inner length. while the respective outer edges of the holding struts extend in the extension of the hollow cylindrical wall part and resiliently apply to the inner wall of the mouth opening with a holding pressure which is greater than the holding force on a holder which introduces the pourer into the mouth opening of the container.
  • the holding struts connect with their upper edges to the lower edge of the hollow cylindrical wall part.
  • the inner cylinder part For connection to the cap before and during the assembly process, it is expedient for the inner cylinder part to protrude into the interior of the hollow cylindrical wall part with a fixed jacket section.
  • the inner cylinder part extends approximately to the level of the lower sealing flange surface covering the edge of the mouth opening.
  • each holding strut has a radially inwardly directed step on its lower edge region, which is characterized by a first oblique edge and a subsequent, approximately axially parallel edge is formed.
  • the axial length of the holding struts is dimensioned such that the holding struts overlap the narrowest point of the constriction.
  • the inner cylinder part is provided with an opening whose inner diameter corresponds to the outside diameter of a mandrel of the assembly tool or the cap.
  • the insert can also be used to dispense meterable quantities of the container contents, it being advantageous for a metering element to be inserted in the inner cylinder part.
  • the metering element is designed as a drip insert, with a liquid discharge opening, ei ner in a cavity of the drip insert liquid inlet opening and at least one air inlet opening in the container.
  • the holding struts extend at their upper ends into an annular channel formed by the outer walls of the cylindrical part and the inside of the hollow cylindrical wall part.
  • the inner surface of the inner cylinder part has stepped sealing surfaces which interact with form-fitting, complementary sealing surfaces on the outer wall of the drip insert.
  • the free inside diameter of the liquid discharge opening of the metering element corresponds to the outside diameter of a mandrel of the assembly tool or the cap.
  • the pouring spout according to the invention is simple to produce if the holding struts are formed in one piece with the inner cylinder part.
  • the sealing flange has an upper annular groove, which cooperates elastically with the assembly tool and / or an annular bead in the inner surface of the cap.
  • FIG. 1 shows an exemplary embodiment in which a pourer 11 has already been inserted into a mouth opening 2 of a neck 3 of a container 1, for example a bottle.
  • the container 1 can have an external thread 4 on its neck and a transfer ring 5.
  • a cap 6 with an internal thread 7 and a central pin or mandrel 10 and / or an annular bead 9 on the inner base 8 can be connected to the container 1.
  • the pourer 11 has a sealing flange 13 which at least partially covers an edge 12 of the mouth opening 2 of the container 1.
  • the pourer 11 has a hollow cylindrical wall part 15 which bears against the inner wall 14 of the mouth opening 2.
  • the pourer 11 is provided with holding struts 16, 17 and 18 which, with their outer longitudinal edges 20, 21 and 22, press against the inner wall 14 of the mouth opening 2 of the container 1.
  • the holding struts 16, 17 and 18 are connected to an inner cylindrical part 19, preferably formed in one piece, a free jacket section 23 of the inner cylindrical part 19 extending into the region of the hollow cylindrical wall part 15 of the spout 11, preferably up to that through the lower surface of the sealing flange 13 formed level.
  • the struts 16, 17 and 18 are provided at their lower ends with steps 24, which are formed by a bevel edge 25 and an adjoining axially parallel edge 26.
  • the axial length of the holding struts 16, 17 and 18 is selected such that the holding struts 16, 17 and 18 overlap the narrowest point 37, i. H. the axial length of the holding struts 16, 17 and 18 is greater than the distance of the constriction 37 from the upper edge 12 of the mouth opening.
  • the sealing flange 13 of the spout 11 has an upper annular groove 36 which cooperates with the annular bead 9 in the cap 6, such that before the cap 6 is screwed onto the bottle 1, the spout 11 has a positive fit. is held elastically in the cap 6.
  • the cap 6 can be provided with gripping grooves or gripping ribs (not shown) in order to facilitate screwing on and unscrewing by the user.
  • the cap 6 can also have a tamper-evident device (not shown) which interacts, for example, with the transfer ring 5.
  • a spout 11 can be clearly seen from the perspective oblique view of FIG. 2.
  • three struts 16, 17, 18 are provided, which are formed triangularly or star-shaped at the same angular distances on the inner cylinder part 19.
  • the design is such that the upper edges of the holding struts 16, 17, 18 connect to the lower edge of the hollow cylindrical wall part 15.
  • the inner cylinder part 19 is designed as a hollow cylinder and has a continuous opening 27.
  • the inside diameter of the opening 27 is chosen such that it corresponds to the outside diameter of the mandrel or the pin 10 of the cap 6, so that the spout 11 is held in the cap 6 in an elastically clamping manner until the closing process or the screwing-on process has ended.
  • the direction of the holding struts 16, 17, 18 and their outer diameter is selected such that the contact force on the inner wall 14 of the mouth opening 2 is greater than the holding force between the inner cylindrical part 19 and the central pin or mandrel 10 of the cap 6.
  • the design is such that a drip insert 28 can be inserted into the inner cylindrical part 19.
  • the struts 16, 17, 18 extend into an annular channel 33, which is between the outer wall of the inner cylinder rule's part 19 and the inner wall of the hollow cylindrical wall part 15 is formed.
  • the drip insert 28 has, in a manner known per se, a liquid discharge opening 29 and a liquid inlet opening 30 which extends into the container 1.
  • At least one air inlet opening 32 is provided in the wall area 31 of the drip insert 28, which creates a connection between the outside air and the interior of the container.
  • the drop size can be determined.
  • a stepped sealing surface 34 is expediently provided on the inner cylindrical part 19, which interacts with a complementary stepped sealing surface 35 on the drip insert 28.
  • the sealing flange 13 with the hollow cylindrical wall part 15 on the one hand and the holding struts 16, 17, 18 and the inner cylindrical part 19 are expediently made in one piece from elastic plastic.
  • the holding struts 16, 17 and 18 which can adapt elastically resiliently to the diameter tolerances of the mouth opening 2, a substantially greater axial contact of parts of the pouring insert 11 in the mouth opening 2 is ensured than is possible solely with the hollow cylindrical wall part 15 would be possible. Since the lower ends of the holding struts 16, 17 and 18 protrude freely into the mouth opening 2, they can expand radially elastically or be compressed accordingly in the case of minus tolerances. The required adhesive force between insert 11 and mouth opening 2 is ensured in any case. The relatively narrow holding struts 16, 17 and 18 do not impede the pouring process or the dripping process when using a drip insert 28.
  • the pourer 11 according to the invention can of course also be used in containers 1 which have no screw thread and are closed, for example, with an elastic snap cap.
  • the annular bead 9 on the lower base 8 of the cap 6 can also perform additional sealing tasks in cooperation with the upper annular groove 36 in the sealing flange 13.
