Definitions

  • the invention relates to a spray container according to the preamble of claim 1.
  • Spray containers of this type are used, for example, to dispense a plastic sealing compound, such as is used for example for elastic joint seals, through the nozzle.
  • a plastic sealing compound such as is used for example for elastic joint seals
  • known spray containers remain after the plastic has been used up Sealant is a residual amount of this material because it cannot be completely dispensed from the container. This can be disadvantageous if the mass remaining in the container makes it difficult to reuse the container material, which is generally made of plastic, and / or if this mass should not be thrown away when the emptied container is thrown away for environmental reasons.
  • EP-A-0 039 245 already shows such a spray container, in which the spray nozzle projects with a piece of pipe into the connecting piece, the diameters of the parts being matched to one another.
  • the free end of the pipe section is provided with thorn-like projections in order to penetrate a membrane which seals the spray container when the spray nozzle is inserted.
  • the spray nozzle with the pipe piece must be pushed into the container and consequently protrudes into the interior of the container.
  • the piston hits the protruding pipe section, so that plastic mass must inevitably remain in the container and complete emptying into the nozzle is not possible.
  • a pushing of the piston up to the inner end face of the spray container is also prevented by the remaining parts of the membrane and, above all, the attachment approaches thereof in the spray container.
  • the invention has for its object to provide a way by which it can be prevented that considerable amounts of the plastic content of the container remain in the area of the connecting piece of the container.
  • the advantage of the invention is that the remaining plastic material that cannot be discharged from the container in the area of its connecting piece is inside the tube and remains in the tube remaining on the spray nozzle when the spray nozzle is removed from the container.
  • the removed spray nozzle can either be recycled by returning it to the manufacturer, or, if the work to be carried out has not yet been completed, the spray nozzle removed from one container is placed directly on another container, so that the remaining in the pipe section and material that has not yet hardened or has otherwise become unusable can be used immediately. If the contents of a large number of spray containers are thus processed with one and the same spray nozzle, only the content of a single spray nozzle remains as unsustainable remainder; namely, the contents of the spray nozzle cannot be removed from the user in general.
  • the container and the nozzle are advantageously made of plastic.
  • the free end of the connecting piece of the container is generally closed by a cover which is integrally molded onto the connecting piece and which has to be removed before use. So that this can be done easily and securely with a knife, in one embodiment of the invention an at least partially annular groove extending along the circumference of the connecting piece, or a ring switch is provided, which forms a guide for a knife or other cutting tool. This ensures above all that the connecting piece is not cut off too short and thus the pipe section does not protrude too far into the container. It may be advantageous to ensure that this groove is not strongly indented at its base in order to prevent a notch effect and an undesired detachment of the cover from the connection stub at an inappropriate time.
  • the shape of the outer surface of the end wall is preferably adapted approximately to the inner surface and is provided on its outer edge with elastic webs, in particular a ring web, projecting in the direction of the spray nozzle. These webs are in the gun, in which the spray container is inserted, and they ensure that the push-out piston is pressed particularly strongly, especially on the outer edge, so that the plastic mass is displaced inward toward the nozzle.
  • a container 1 made of plastic which is only shown in the region of its end serving to discharge its filling, has an essentially cylindrical connecting piece 2, which has an external thread 4 and is arranged centrally in the region of the end wall 6 of the container. If the container has not yet been used, the connecting piece 2 is closed at its end by a cover 8 which is integrally molded during the manufacture of the container 1. In order to enable a simple removal of the cover 8 by means of a knife or other cutting tool, an annular shoulder 12 is provided which extends around the entire circumference of the connecting piece 2 and forms a guide preventing the knife from slipping off.
  • a spray nozzle designated by reference number 20 has the actual nozzle 22.
  • the spray nozzle 20 has in its end region facing away from the nozzle 22 an internal thread 26 which fits the external thread 4 and enables the spray nozzle 20 to be screwed onto the connecting piece 2 (after the cover 8 has been removed).
  • an internal thread 26 which fits the external thread 4 and enables the spray nozzle 20 to be screwed onto the connecting piece 2 (after the cover 8 has been removed).
  • a pipe section 28 which is injection-molded in one piece with it.
  • the pipe section 28 extends through the interior of the internal thread 26 and ends in the example with the internal thread 26. Then, when the spray nozzle 20 is attached to the connection piece 2 by screwing, the pipe section 28 fills the connection piece 2 inside almost all of it length on (the pipe section can be made a little longer if necessary).
  • the outer diameter of the pipe section 28 is equal to the inner diameter of the connection piece 2 or only slightly smaller, so that on the one hand an easy screwing of the spray nozzle onto the connection piece is possible and on the other hand in the area between the outer wall of the pipe piece 28 and the inner wall of the connection piece 2 no disturbing large amounts of the plastic content of the container 1 can reach.
  • the inner surface 5 of the connecting piece 2 having the end wall 6 of the container 1 has an arc shape adapted to the pressure plate 30 of the push-out piston 31 in order to keep the remaining space between the pressure plate 30 and the inner surface 5 of the container and thus the remaining amount of the plastic mass low.
  • the radius 32 of the arc of the pressure plate 30 is kept slightly smaller than that 33 of the inner surface 5, this ensures that when the pressure plate 30 is pressed against the inner surface 5 of the pressure plate, it first lies against the inner surface and then presses further spreads, so that the remaining amount is displaced from the outside in and pressed into the spray nozzle 20.
  • the outer surface 7 of the end wall 6 of the inner surface 5 is adapted and also provided on its edge with an elastic ring web 9.
  • This ring land becomes very strong in the position of the push-out piston 31 shown pressed the corresponding surface of the gun, not shown, so that the pressure plate of the ejection piston 31 abuts especially at its edge close to the inner surface 5 of the end wall 6 and so the material is largely pressed into the spray nozzle 20 from the outside. In this way, the remaining amount in the container 1 is reduced to a minimum.
