Definitions

  • the invention relates to a container for plastic adhesives, fillers, sealants or fillers, with an essentially cylindrical sleeve, a dispensing opening at one end of the sleeve and an ejection piston which is axially displaceably mounted within the sleeve, as described e.g. is known from US-A-2 649 999.
  • plastic single or multi-component materials are used for different purposes.
  • the masses In order to avoid premature curing of the masses, the masses usually have to be stored in an air-tight environment. As a rule, this is done by packing the masses in sleeve-shaped containers with an ejection piston mounted axially displaceably therein.
  • the outer diameter of the ejector piston is usually matched to the inside diameter of the sleeve-shaped container.
  • the excess of the squeezing piston is very small compared to the sleeve-shaped container.
  • the invention is therefore based on the object of improving the sealing of the squeeze-out piston in the container in order to improve the storage of plastic masses, without the displacement resistance of the squeeze-out piston being significantly increased.
  • this is achieved in that a sealing ring which is at least detachable with respect to the squeezing piston is provided between the squeezing piston and the sleeve to close the sleeve end opposite the dispensing opening.
  • the sealing ring is thus inserted between the squeezing piston and the sleeve wall, at least remaining detachable relative to the squeezing piston.
  • the sealing ring therefore has no influence on the displacement resistance of the ejection piston.
  • the sealing ring thus acts as a static seal during storage of the container.
  • the sealing ring can remain in the container and can only be separated from it by pushing the ejection piston forward.
  • a certain resistance may occur at the beginning of the squeezing process, which must first be overcome.
  • the sealing ring it is expedient for the sealing ring to be arranged releasably with respect to the squeezing piston and the sleeve. This means that the sealing ring can be removed from the container before the pressing process begins.
  • the displacement resistance of the squeezing piston thus remains constant during the entire squeezing process.
  • the sealing ring can be designed as desired.
  • the sealing ring can adapt, for example, in the manner of an O-ring in a recess provided for this purpose.
  • An advantageous embodiment of the sealing ring is that the cross section of the sealing ring decreases in the squeezing direction. With this cross-sectional shape, the sealing ring can be pressed like a wedge between the squeezing piston and the sleeve wall. The wall of the sleeve is pressed outwards and the ejection piston is pressed inwards.
  • a simple design of the press-out piston and the sleeve as well as the sealing ring itself is achieved if, in a further development of the invention, the sealing ring tapers conically on its outside in the pressing-out direction.
  • the outer side of the sealing ring which tapers in the pressing direction, makes it easier to insert the sealing ring between the pressing piston and the sleeve wall.
  • the sleeve wall is pressed radially outwards.
  • the sealing surface between the sealing ring and the sleeve is thus conical, which gives a good sealing effect.
  • the sealing surface between the sealing ring and the squeezing piston can also be conical or cylindrical.
  • the sealing ring is inserted between the sleeve and the squeezing piston. So that the sealing ring is always pushed in to the same extent, it is advantageous that a stop shoulder is provided on the sleeve for the discharge-side end face of the sealing ring. In addition to the limitation when pressing in the sealing ring, the stop shoulder can also perform another task. This consists in that the sealing ring is retained by the stop shoulder when the ejection piston is pushed forward. The sealing ring is thus simply pushed forward by the ejection piston separated from this.
  • the sealing ring can remain in the container and be separated from it only by pushing the ejection piston forward.
  • the initial displacement resistance of the ejection piston can be high.
  • the sealing ring it is expedient for the sealing ring to have a tab which serves to remove the sealing ring.
  • the tab can be integrally formed with the sealing ring or connected to it by gluing or pouring. The sealing ring is removed by pulling the tab. If necessary, the sealing ring can also have several tabs.
  • the sealing ring In order to facilitate the removal of the sealing ring, it can also be formed in one piece with a cover-shaped protective cap.
  • the sealing ring is thus removed together with the protective cap before the pressing process begins.
  • a protective cap in particular prevents dirt from penetrating into the mostly hollow ejection piston.
  • an unintentional displacement of the squeezing piston is prevented by a protective cap.
  • the container shown in Fig. 1 consists of a sleeve, generally designated 1, in which an ejection piston 2 is axially displaceably mounted.
  • the sleeve 1 has a discharge opening 1a at a sleeve end.
  • the discharge opening 1a is closed by a destructible membrane 1b.
  • a thread 1c arranged at the discharge opening 1aa serves to screw on a discharge nozzle.
  • a mass 3 to be dispensed is arranged in the cavity formed by the sleeve 1 and the squeezing piston 2. Before the start of the dispensing process, the membrane 1b is destroyed.
  • the sleeve end opposite the discharge opening 1 a is closed by the ejection piston 2.
  • a sealing ring 4 is inserted between the squeezing piston 2 and the sleeve 1.
  • the sealing ring 4 is conically tapered on the outside in the pressing direction. With this design, the sleeve wall is pressed radially outwards. The sealing ring 4 lies against a stop shoulder 1d of the sleeve 1. When the ejection piston 2 is pushed forward, the sealing ring 4 is retained by the stop shoulder 1d. The displacement resistance of the squeezing piston 2 is thus influenced by the sealing ring 4 only at the beginning of the squeezing process.
  • FIG. 2 of a sealing ring denoted overall by 5 shows a tab 5a connected to the sealing ring 5.
  • the sealing ring 5 can thus be removed simply by pulling on the tab 5a.
  • the displacement resistance of the squeeze-out piston 2 remains constant from the start in the sleeve designated overall by 1.
  • the sealing ring 5 is also pressed until it comes up against a stop shoulder 1 d of the sleeve 1 between the squeezing piston 2 and the sleeve 1.
  • the end of the sleeve 1 opposite the discharge opening is additionally closed by a protective cap, designated overall by 6.
  • the protective cap 6 is connected in one piece to a sealing ring 6a. When the protective cap 6 is removed, the sealing ring 6a is thus also removed.
  • the protective cap 6 also forms a mechanical protection of the container. This prevents dirt from penetrating into the hollow squeezing piston 2.
  • the protective cap 6 also prevents the pressing-out piston 2 from being moved unintentionally.
