Definitions

  • the present invention relates to a one-part or multi-part stopper on a discharge cartridge according to the preamble of claim 1.
  • Discharge cartridges are used for the targeted and metered application of adhesives, sealants and other highly viscous compounds in many areas. Examples include industry, construction and dental technology.
  • multi-chamber mostly two-chamber cartridges for two-component compounds.
  • the chambers of these cartridges, and of course the single-chamber cartridges, must be tightly sealed before use.
  • plug-in plugs are common, which are manufactured separately from the cartridges, are inserted into the outlet opening of the cartridge before filling and are secured by means of a union nut.
  • the first possibility suffers from the fact that this special tool is not always at hand and that it needs a separate tool for each cartridge type.
  • the second option makes the stopper more expensive and also increases the storage volume of the cartridge, since the extension must be made quite stable and large in order to be easy to grasp manually.
  • a stopper according to the preamble of claim 1 is known from EP-A-0 431 347, with the securing means being unlocked and removed in all versions for pulling out the stopper the stopper is then pulled out, whereby the disadvantages described above also come into play here.
  • An object of the present invention is to provide a stopper that can be removed from a discharge cartridge without tools.
  • the plug is inserted into the discharge opening of the cartridge and, if necessary, pressed in and locked by means of a screw ring or the like.
  • the stopper has an extension projecting beyond the screw ring.
  • a trigger is now attached laterally over the end of the screw ring and grasping the extension.
  • This trigger means is designed in such a way that the screw ring can be rotated relative to the stopper since it has to be unscrewed from the discharge opening again in order to replace the stopper against the discharge nozzle. When unscrewing, however, a pulling force is transferred to the stopper thanks to the pulling means and the stopper is thus pulled out.
  • the plug 1 shows the plug 1 with the screw ring 3 surrounding it.
  • the screw ring 3 has an inner bevel 5 against which the shoulder 7 of the plug 1 lies and which can press it into the discharge opening of the cartridge.
  • the extension of the plug 1 is designed here as a pull plate 12 which projects beyond the screw ring 3 and is connected to the body of the plug 1 via a neck 13.
  • the trigger means 15 is designed as a slotted disc.
  • the slot 16 can receive the neck 13 and the disc 15 is slightly thinner than the neck 13 is long.
  • the disk 15 can be pushed according to the arrow 17 over the upper edge of the screw ring 3 under the tension plate 12, which results in the state according to FIG. 4.
  • the screw ring 3 is simply unscrewed, the stopper 1 also being pulled off. It is important that the disc 15 can slide easily enough under the pressure forces during the removal either on the upper edge of the screw ring 3 and / or can twist relative to the plug 1.
  • a generally U-shaped trigger can be used, the legs of which grip the extension on the stopper between them.
  • the base of the U and also the leg ends are advantageously made flat, so that the screw ring can be turned underneath.
  • the rotatability around the plug extension can also be sufficient.
  • the leg ends, as well as the slot ends of the disk 15, can be funnel-shaped will.
  • the pulling means can advantageously spread out at the inserted end and / or have barb elements in order to prevent falling out. It is also possible to carry out one leg while a second leg encompasses the neck.
  • an elongated trigger means made of a resilient material in the manner of a clip 19, as shown by way of example in FIG. 6. If it is in principle U-shaped, it can be pushed laterally over the neck 13, after which the legs encompass the neck of the extension. An expansion adapted to the neck can preferably be provided in the legs, as a result of which the trigger means snaps onto the neck 13 of the extension. It is also possible to use a shape closed on both sides, roughly corresponding to an elongated oval, and advantageously to provide the extension with a tapered end. The trigger is then placed on the extension from above, the tapered end expanding the trigger against the spring force by the wedge effect, and the trigger then snaps into the taper. Here, too, a preferably central widening of the legs can be provided in order to prevent undesired lateral displacement.
  • another part securing the stopper on the discharge opening 9 may also be present, e.g. B. one with a bayonet catch.
  • this part since this part is designed for manual operation, simply pulling on it is sufficient to exert the force required to pull out the plug. In these cases, only a limited rotatability of the trigger means relative to the securing part or the stopper has to be guaranteed if the securing means is caused by a rotary movement must be unlocked, which makes the solution with pens etc. applicable in particular.
  • the cartridges can also only be delivered with the plug inserted, i.e. H. without the screw ring 3. This is usually available at the place of use, e.g. B. if it is used to attach the mixing attachment or the discharge nozzle to the cartridge.
  • the specified round parts can also be other, e.g. B. rectangular or polygonal outlines show how particularly the disc 15 and the tension plate 12.
  • the neck 13 can be changed up to a web extending over the entire width of the tension plate 12. It is also possible to provide in the neck 13 fastening elements, such as depressions or elevations, which correspond to corresponding complementary designs on the trigger means 13 and secure it against falling off.
  • the cartridge consists of separately manufactured and optionally separately filled individual bodies, the outlet openings of which can be combined with the partial plugs therein to form one of the embodiments or modifications presented.
  • section line 20 shows a possible division of the stopper into two. The bracket 19 and the rod 18 as well as the screw ring 3 are each in one piece. The two part plugs are then pulled out together.
