Definitions

  • the innovation relates to a pouring spout for piercing into a liquid container with a base body having a tip for piercing into the wall of the liquid container and a passage for liquid to be poured, a displaceably arranged on the base body, which can be placed on the edge of the puncture hole against the outside of the container wall, an intermediate part the stop part and the tip arranged on the base body, which can be inserted into the interior of the container when piercing, and which rests with one end against the stop part and with its other end against an annular stop formed on the base body and which forms around the edge of the puncture hole
  • Clamping gap between the stop part and the clamping sleeve part is compressible with radial expansion, and with a device for moving the stop part relative to the base body and for locking the connection partially in a clamped position.
  • the spout described in the US patent has a base body which consists of a tube which is connected at one end to a cone part having a tip.
  • a liquid inlet which is in fluid communication with the passage and which opens towards the conical surface of the conical part and through which Liquid can get into the tube and can be poured out over the tube.
  • the end face of the conical part facing away from the tip forms an annular stop for an elastic clamping sleeve part arranged on the tube.
  • the clamping sleeve part has the same diameter as the abutting end of the cone part.
  • the diameter of the clamping sleeve part, which is also conical, decreases toward the stop part.
  • the stop part can be moved via a lever mechanism which can be pivoted about an axis which is fixed with respect to the tube.
  • the lever mechanism has a curved edge which slidably abuts against the stop, so that when the lever is moved the stop part is moved through the curved edge and the clamping sleeve part is pressed together by the stop part.
  • the largest diameter determining the size of the puncture hole is given by the maximum diameter of the conical or clamping sleeve part. This maximum diameter should be kept as small as possible to avoid tearing the edge of the hole as much as possible, which could lead to the risk of leaks. Since the diameter of the clamping sleeve part decreases towards the stop and becomes smaller than the diameter of the puncture hole produced, there is the possibility that the spout is not properly centered with respect to the puncturing hole in the clamped state and thus only an insufficient seal of the clamping sleeve part Puncture hole is reached.
  • the present innovation solves the task of creating a spout that is improved in its performance properties.
  • the spout according to the present innovation is characterized in that the ring stop is provided with a rim for the end of the elastic clamping sleeve part abutting against the ring stop.
  • This solution according to the invention achieves a considerably increased reliability by ensuring that the end of the clamping sleeve part abutting against the ring stop ensures that the end of the clamping sleeve part cannot slide over the ring stop when pressed together.
  • the functionality is thus preserved, especially with smaller maxi diameter of the puncture hole.
  • the edge surround has one against the ring stop End of the elastic clamping sleeve part comprising ring web.
  • the annular web rests with its entire edge against the clamping sleeve part compressed to a bead, whereby a particularly effective sealing of the puncture hole is achieved by preventing liquid from being able to penetrate to the outside between the inner wall of the clamping sleeve part and the base body.
  • the outer diameter of the rim of the ring stop is only slightly larger than the outer diameter of the clamping sleeve part, which is bordered by the ring web.
  • the outer diameter of the border is decisive for the size of the puncture hole and, with the diameter of the clamping sleeve part remaining the same in the direction of displacement of the stop part, a relatively precise centering of the spout within the puncture hole and thus an effective seal can be achieved by this measure.
  • FIG. 2 shows the exemplary embodiment of FIG. 1 in a liquid container and in the Wall of the liquid container attached state
  • FIGS. 1 and 2 show a conical part having an ice piercing tip of the exemplary embodiment shown in FIGS. 1 and 2 for a pourer according to the invention in a sectional illustration
  • FIG. 7 shows another embodiment of a spout according to the invention with a handle for holding the spout when fastened to a liquid container.
  • the reference numeral 1 denotes a tube which, together with a cone part 2 having a tip 3, forms a main body of the spout. As can be seen from FIG. 5, the tube has a thread 4 at one end, which can be screwed into a thread 5 visible in FIGS. 3 and 4 in the cone part 2.
  • the reference numeral 6 in FIGS. 1, 2 and 5 denotes a cap that can be placed on the tube 1. Via a pin 7 projecting through the tube 1, the tube 1 is connected to a lever 8 which is provided with a cam curve 9. The lever has two to each other Lever legs arranged congruently on opposite sides of the tube, which are connected to one another via a web 10. With the reference numeral 11 in Fig.
  • a first socket part 12 and a second socket part 13 are provided on the tube 1 screwed to the cone part 2.
  • the first socket part 12, which bears against the second socket part 13 has at its end facing the lever 8 a cap-like flange 14 with a peripheral surface area having a surface profile.
  • the socket part 13, which, like the socket part 12, is displaceable on the tube 1, has a flange 15 at its end facing away from the first socket part 12.
  • all the parts of the spout described so far consist of a plastic material.
  • the rubber part 16 forming a tube section rests with its one end on the flange 15 of the second bushing part 13 and with its other end on the cone part 2.
  • the inner diameter of the rubber part 15 is slightly larger than the outer diameter of the tube 1, so that the rubber part can be easily pushed onto the tube.
  • the inside diameter of the rubber part and the outside diameter of the tube could also be dimensioned such that the rubber part seated on the tube exerts a slight contact pressure against the tube.
  • the screwed to the tube 1 via the threads 4 and 5, having a piercing cone part 2 forms for the the cone part facing end 16 an annular stop 17, the end of the rubber part 16 in the present exemplary embodiment being framed by a socket designed as a continuous ring web.
  • a socket designed as a continuous ring web.
  • the stop surface 18 of the annular stop 17 has a surface profile formed by protruding blocks 19.
  • teeth with sharper edges could also be provided, for example.
  • the ring web 20 enclosing the abutting end of the rubber part has a relatively small width, so that the outside diameter of the ring web is only slightly larger than the outside diameter of the rubber part.
  • the reference numeral 21 in FIGS. 3 and 4 denotes a recess formed in the cone part, which is in connection with the formation of a liquid passage with slots 22 formed in the cone wall.
  • the recess 21 has at its upper end the internal thread 5, which is in engagement with the external thread 4 of the tube.
  • the distance between the ring stop 17 and the flange 15 is advantageously somewhat smaller than the length of the rubber part 16, so that the rubber part is under a low compressive stress.
  • the spout according to the invention is intended in particular for liquid containers having cardboard walls, for example for fruit juices.
  • the spout is pierced in the state shown in FIG. 1 in a wall 23 of the liquid container, the user advantageously holding the spout on the flange 14 having a profiled peripheral surface and, if necessary, to facilitate insertion, the spout with the aid of the Flange 14 twisted.
  • the formation of one free from tears Edge of the puncture opening are supported. Since the rubber part 16 is under slight compressive stress and a toothed support surface of the ring stop preventing rotation of the rubber part against the cone part is provided, a rotary movement of the flange can be transmitted to the cone part.
  • the size of the puncture opening is determined by the outer diameter of the ring web, which surrounds the end of the rubber part 16 facing the cone part 2.
  • the spout can be inserted into the liquid container at most until the flange 15 forming a stop comes into contact with the container wall 23. By actuating the lever 8, the spout can now be attached to the container wall while sealing the puncture opening.
  • the user of the spout When the lever 8 is moved, the user of the spout preferably holds the spout firmly at the upper end of the tube 1 so that he can exert a corresponding counter-torque to the torque exerted on the lever 8 via the tube 1.
  • the lever 8 rotates, there is a relative movement between the tube 1 and the bushing parts 12 and 13 lying against one another, by the axis of rotation pin 7 in the direction away from the flange 14 due to the cam curve 9 of the lever 8 sliding against the cap flange 14 of the bushing part 12 is moved.
  • the above ring bridge 2 . 0 of the ring stop 17 prevents the rubber part 16 from slipping laterally beyond the ring stop, which would make it impossible to compress the rubber part to form the clamping gap.
  • the socket formed by the ring web 20 ensures a safe functioning of the spout for the end of the rubber part facing the cone part.
  • the socket is designed as a continuous ring web, which, when the rubber part is compressed, rests as a closed ring against the rubber part, the ring web ensures a particularly effective seal by preventing liquid from entering the space between the rubber part 16 and the tube 1 , which forms when the rubber part 16 is compressed, can penetrate.
  • the cap 6 is removed and the liquid container is inclined so that the liquid to be poured passes through the inlet slots 22 into the recess 21 in the conical part 2 and from there via the tube 1 to the outside.
  • the socket part 12 could also be formed in one piece with the socket part 13.
  • FIG. 6 shows an angled liquid pouring tube la, which could be used instead of the straight tube used for a pourer in the exemplary embodiment described above.
  • the angled tube la above all has the advantage that the spout can be held more easily when the lever 8a is actuated and a counter-torque can be exerted by the angled part of the tube la projecting further from the lever 8a and thus there are better gripping possibilities for holding .
  • a cap flange part 14b has a lateral grip nose 24 arranged below the lever 8b.
  • a counter-torque can advantageously be exerted via this grip lug when the lever 8b is moved, in that the user of the pouring spout places the grip lug 24 on the index finger and with the index finger while moving the lever 8b, while pressing the lever 8b towards the grip lug with the thumb 24 depresses, exerts a counterforce.
