Definitions

  • the invention relates to a filler neck made of plastic with a flexible plastic bag, the filler neck being able to be passed through a corresponding opening in a wall part of a dimensionally stable receptacle for the plastic bag.
  • the object of the invention is to propose a filler neck of the type described in the introduction, which is held securely in place by simple means.
  • the filler neck is inserted in a sufficiently large bore in the wall part and the externally projecting part is connected to an additional locking piece which is supported both on the filler neck and on the wall part mentioned and thereby holds the filler neck in position.
  • the filler neck can be held securely in a corresponding hole in the packaging, so that the still empty flexible plastic bag in the packaging can be filled without problems.
  • the filler neck can of course be designed so that it can wear a closure or a closure cap and can be sealed.
  • the construction is also variable so that the locking piece can also serve as tamper-evident.
  • Figure 1 shows in longitudinal section a simple filler neck with an unspecified filler opening and an external thread 48 for a sealing lid that may be used.
  • the external thread 48 ends at the bottom in an outlet groove, which is followed by a circumferential collar 11.
  • the diameter of this circumferential collar can be larger than the diameter of the external thread.
  • the circumferential collar 11 is followed in turn by an unspecified outlet groove, which is followed by a centering seat 27.
  • a wall part 8 for example made of corrugated cardboard of a cardboard box, has an opening corresponding to the centering seat 27 and the filler neck 1 is guided through this opening until the centering seat 27 has centered in the above-mentioned opening of the cardboard box 8.
  • the cardboard lies on the unspecified lower edge of the filler neck, which is connected to the flexible plastic bag.
  • the diameter of the opening of the cardboard box can be quite smaller than the diameter of the circumferential collar 11.
  • the cardboard box is generally sufficient elastic to bridge such a difference in diameter.
  • An annular collar 20 is used as the locking piece 10, which is designed as a circular disk with a sufficiently large central opening and is curved in the manner of a plate spring.
  • the mentioned opening 26 is again smaller in diameter of the circumferential collar 11.
  • Various measures are possible so that the opening 26 can nevertheless be pushed over the circumferential collar 11.
  • the ring collar 20 consisting of a relatively elastic plastic participates in a corresponding widening of the opening 26 so that this opening 26 can be pushed over the ring collar 11, whereupon this opening 26 then contracts again.
  • the annular collar 20 it is also conceivable for the annular collar 20 to be distributed around the circumference of the opening 26 for this purpose and to have a series of radial incisions so that the opening 26 can widen.
  • the circumferential collar as shown in FIG. 8. There, a filler neck 7 is shown in plan view, which could correspond entirely to the filler neck 1.
  • the filler neck 7 In contrast to the filler neck 1, the filler neck 7 only has no closed circumferential collar 11, but rather a circumferential collar 14 which is interrupted by incisions 19 running parallel to one another, so that only tongues 18 remain from a closed circumferential collar. These tongues 18 are then relatively flexible and can bend during the slipping on of an annular collar 20 and thereby assume a smaller diameter. After the ring collar 20 has been completely slipped on, these tongues 18 can straighten up again and can thus serve as an abutment for a locking piece 10 designed as a ring collar 20.
  • the incisions 19 are expediently all with their main direction parallel to one another and perpendicular to a longitudinal section plane of the filler neck, because this enables demoldability in a shape that is only divided into two.
  • the annular collar 20 after it has once reached under and is supported on the circumferential collar 11, rests with its outer region on the outer surface of a wall part 8 and thus always pulls the filler neck 1 outwards, or at least holds it in position.
  • the wall part 8 is thus always clamped between the Ring collar 20 on the one hand and the inner collar 49 with the plastic bag 50 on the other hand.
  • the annular collar 20 distributed on the outer lower circumference still have locking cams 51 which can penetrate into the outer layer of coarse corrugated cardboard as the wall part 8, so that even an increased pressure from the outside against the filler neck 1 cannot push it back because up to a certain limit, the ring collar 20 is prevented from lying flat due to the locking cams 51 penetrating the corrugated cardboard.
  • a certain thickness range of the thickness of the wall part 8 can be controlled with the tension of the curved ring collar 20.
  • Figure 2 shows an embodiment similar to Figure 1.
  • the filler neck 2 also has an external thread 48, which can also be designed as a bayonet lock, so that the filler neck 2 can be covered by a cap 52.
  • the filler neck 2 according to FIG. 2 has an external thread 15, which in turn is arranged above a centering seat 27 and ends.
  • a flat ring collar 21 is provided as the locking piece 10, the opening 26 of which is adapted to the external thread 15, so that the ring collar 21 can be screwed on like a threaded nut and can thereby be brought into contact with the outside of a wall part 8.
  • a centering seat 27 again ensures the correct position.
  • the annular collar 21 can be provided in the manner of a lock nut with grooves 53 arranged distributed around the circumference. In this way too, the wall part 8 is pressed and held against the inner collar 49 of the filler neck 2 with the plastic bag 50. The filler neck 2 is in turn held securely in place. It is also conceivable here to design the annular collar 21 to be as curved as the annular collar 20.
  • FIG. 5 A further variant is shown in FIG. 5, the filler neck 5 of which is very similar to the filler neck 1 according to FIG Filling spout 5 corresponds.
  • a circumferential groove Below the circumferential collar 13 there is again a circumferential groove, which is again followed by a centering piece 27, which, however, is lower in height than the wall material 9 to be clamped in, so that a certain thickness range of this wall material 9 can be controlled.
  • a flat ring collar 24, the opening 26 of which is smaller in diameter than the diameter of the circumferential collar 13, is used as the locking piece 10.
  • the possibilities of still grazing the ring collar 24 over the circumferentially larger collar 13 have been further expanded already described above.
  • FIG. 3 in turn shows a filler neck 3 with a closed circumferential collar 12.
  • an external thread 55 is again provided for a cap 56.
  • This cap 56 is connected via a plurality of tabs distributed at its lower end in the circumferential direction to an annular collar 22, which essentially corresponds in shape to the annular collar 20.
  • the outer diameter of the circumferential collar 12 is larger than the inner diameter of the opening 26 of the ring collar 22. If the cap 56 is put on, the ring collar 22 can be guided over the circumferential collar 12 and snap in behind it.
  • the wall part 9 is now held again by the ring collar 22 as has already been described for FIG. 1. At the same time, however, tamper evidence has now been achieved.
  • the tabs 55 are destroyed and tear off the ring collar 22, which remains in its position. Since the outer diameter of the circumferential collar 12 can also be kept larger than the diameter of the opening in the wall part 9 and thus larger than the diameter of the centering seat 27, the circumferential collar 12 alone can already ensure that the filler neck 3 slides back with sufficient safety for a filling process Prevent cardboard containers. For later use and the emptying process, the filler neck 3 is held in an exact position by means of the ring collar 22.
  • the embodiment according to FIG. 4 also allows tamper evidence. However, in this embodiment, unless special aids are to be used, the plastic bag 50 associated with the filler neck 4 must first be filled, whereupon the cardboard is built around the filled plastic bag.
  • the filler neck 4 has at least one outer annular groove 16, into which an inner bead 28 can snap.
  • This inner bead 28 is located on a bushing 30, which widens greatly downward and thereby forms an annular collar 23, which can be curved corresponding to the annular collar 20 according to FIG. 1. If this bushing 30 is now pushed onto the filler neck 4 from the outside, the inner bead 28 can snap into the outer annular groove 16.
  • Each ring-shaped flat surfaces 57 lying against each other, lying perpendicular to the central axis of the filler neck, ensure that the connection is undetachable.
  • this engagement engages at least the outer peripheral region of the ring collar 23 on the surface of the wall part 9, so that the filler neck 4 is held in position again.
  • the bushing 30 is connected in one piece to a pouring piece 32 via an intermediate piece 35 which is shaped in the form of a ring, this pouring piece 32 having an inner ring 58 being inserted into the opening of the filler neck 4.
  • the filler neck 4 has in its outer region a conically enlarged region 36 which cooperates with a correspondingly conical region 39 of the inner ring 58. In the locked position, the two conical surfaces lie tightly against one another. The angle of inclination or cone angle of this cone is so small that it lies below the self-locking.
  • pouring piece 32 is closed in its pouring cross section with a lid 34, which serves here as tamper-evident.
  • Lid 34 can, however, easily be torn open by means of an eyelet 59, so that the pouring cross section is free. The pouring can be done via the Pouring aid 60 can be facilitated.
  • the pouring cross section can be closed again tightly via a lid 61.
  • the cover 61 can be molded onto the bush 30 with a thin plastic band 62. Again, the filler neck 4 is held securely in position and a tamper-evident device is created at the same time.
  • FIG. 6 A variant of the construction according to FIG. 4 is shown in FIG. 6.
  • the embodiment according to FIG. 6 shows a filler neck 6 which is passed through a corresponding opening in a wall part 9 in the manner already described several times, the filler neck 6 also having a correspondingly dimensioned centering seat 27 .
  • the filler neck 6 has a first outer annular groove 16 and a second outer annular groove 17 at a short distance from one another.
  • a socket 31, which widens in its lower region so that it forms an annular collar 25, also encloses the outer peripheral surface of the filler neck 6 and has an inner bead 21 on its inside, which can snap into the outer annular groove 16, as is the case here has already been described for FIG. 4.
  • the filler neck 6 has on its wall surrounding the inner opening an annular circumferential nose 40 which can snap into a corresponding annular groove 41 in the region of the lower end of a pouring piece 33.
  • annular circumferential nose 40 which can snap into a corresponding annular groove 41 in the region of the lower end of a pouring piece 33.
  • the flat surfaces on the annular circumferential nose 40 and on the annular groove 41 come into mutual contact, so that the pouring piece once inserted and locked in place cannot be pulled out again.
  • slots 42 are provided in the lower region of the pouring piece 33, in which the annular groove 41 is provided, from bottom to top in the longitudinal direction, so that a A large number of individual and thus somewhat more flexible tongues is created. This makes it easier to snap in without the security of locking becoming worse.
  • the filler neck 6 is again provided in its outer opening area with a conically widened area 37, which corresponds to a conical area 38 on the pouring piece 33.
  • the cone angle or angle of inclination of each cone is the same and smaller than the self-locking angle.
  • the pouring piece 33 has a circumferential stop collar 43, which comes into contact with its lower flat surface on the outer flat end face 44 of the filler neck 6 exactly when the nose 40 is snapped into the annular groove 41.
  • the opening cross section of the pouring piece 33 is in turn closed with a thin cover 34, which in turn can be torn out here via an eyelet 59.
  • the then free opening of the pouring piece 33 can again be sealed off with a cover 61, which can be attached to the pouring piece 33 by means of a thin plastic band 62.
  • this construction enables the filler neck 6 to be properly locked in the open state via the ring collar 25, so that the empty plastic bag can be inserted into the packaging and can then be filled. After filling, the pouring piece 33 can be inserted and snapped into place so that there is a tight seal with a tamper-evident device.
  • FIG. 7 A simple variant of a locking piece 10 is shown in plan view in FIG. According to FIG. 7, a locking piece 10 is designed as a simple flat clip 47.
  • a view in the direction of the arrow according to the figure 7 could represent FIG. 5.
  • the legs 63 of the clamp 47 also largely enclose an opening 26 here (FIG. 5) and have at their front ends between them an inlet opening through which the filler neck 5 can be pushed, for example.
  • the bracket 47 is set so that it lies at the level of the circumferential groove under the circumferential collar 13 and has a thickness that is less than the width of this circumferential groove.
  • the clip After being pushed on, the clip is in the arrangement shown in FIG. 7 and thus has the same effect as, for example, the ring collar 21.
  • the clip 47 can be rotated so that the free tongue surface 64 can serve as a drip protection during pouring.
  • the clip 47 can not only be made of a suitable plastic, like all other locking pieces. Rather, training from a sufficiently thick and strong cardboard can also be very useful.
  • Such a clip 47 which is very easy to produce from cardboard, can advantageously be connected to the wall part 9 with a glue point 66 after it has been pushed into position and thus can fulfill its main function. This has particular advantages when disposing of the empty container.
  • the glue point can easily be torn open, so that the clip 47 is in position on the one hand and on the other hand can be removed again with a small jerk so that the inner flexible plastic bag and the receptacle can now be easily separated and disposed of.
  • the legs 63 should have an inner opening limitation, as is shown by the dashed lines 67 in FIG. 7. This opening width corresponds to the diameter to be encompassed at the filler neck 5, so that the clip 47 is easily pushed open.
  • Figure 9 shows a cardboard box 65 with a flexible plastic bag arranged therein, which is connected to a filler neck 1, this filler neck 1 being passed through a corresponding opening of an obliquely positioned wall part 9 and secured there in its position with a locking piece 10 of the type described here .
  • the oblique arrangement of the wall part 9 is particularly advantageous because it means the cardboard box despite the locked filler neck remains stackable. In principle, however, such a filler neck can of course be guided through and locked in any wall of the cardboard box.
