Definitions

  • the invention relates to a slidable bowl bottom made of flexible material for a hollow cylindrical container for squeezing pastes, with an end wall and a casing wall and an annular outer sealing lip located at the transition from the outer end surface to the outer casing surface.
  • Such a slidable bowl bottom is known from DE-PS 20 034 047.
  • This displaceable bowl bottom is present in a cartridge in which the hollow cylindrical container (sleeve) has a mouthpiece at the front and carries the displaceable bowl bottom in the rear region.
  • a cartridge is operated by means of a press (manually operated or pneumatically).
  • a very large force is often exerted on the bottom of the bowl by means of an axially displaceable squeezing piston in order to push out the paste.
  • the paste is e.g. used as a sealing compound in the construction industry, the high squeezing force resulting from the significant viscosity of the paste and / or from the resistance of the paste emerging from the mouthpiece, depending on the exit cross section. As a result of this great squeezing force, the sealing of the bowl bottom on the hollow cylindrical container is a problem.
  • the aim is to create an improved bowl bottom, with which the aforementioned disadvantages can be avoided.
  • the bowl bottom according to the invention is characterized in that the end wall is provided with an annular web lying inside the bowl bottom, which is concentric to the jacket wall and parallel to the longitudinal axis, so that in longitudinal section the jacket wall, the ring web and the intermediate wall part have a U-shape, and that the ring web is connected with a plurality of radially extending ribs to the casing wall over its circumference, and that the end face of the ring web is intended as a flat pressing point for a press-out piston of a press for displacing the bowl bottom in the container.
  • CH-PS 580 491 has already made known a displaceable bowl base, in which the end wall is provided with an annular web located in the interior of the bowl base, which is concentric with the jacket wall and parallel to the longitudinal axis.
  • this known cup base is not intended to be displaced by a squeezing piston of a press, ie this ring web does not serve as a pressing point for the squeezing piston, since the be Known Napfboden is pressurized by a compressed gas. This results in a different distribution of force in the material of the bowl base.
  • the slidable bowl bottom 1 consists of a relatively soft polyethylene. From Fig. 3 a part of the hollow cylindrical container 2 can be seen, within which the bowl bottom 1 is axially displaceable.
  • the paste 3 to be expressed is a sealant e.g. silicone-based.
  • the cup base 1 has an end wall 4, a jacket wall 5 and an annular outer sealing lip 8 located at the transition from the outside end face 6 to the outside jacket surface 7.
  • the end wall 4 is provided with an annular web 9 lying inside the bowl bottom, which is concentric with the jacket wall 5 and is parallel to the longitudinal axis 10. 1 and 3, longitudinal sections of the bowl bottom 1 are shown.
  • the jacket wall 5, the ring web 9 and the end wall part 4 'lying between these parts 5 and 9 have a U-shape (FIG. 3).
  • the annular web 9 and the casing wall 5 there are a plurality of radially extending ribs 11. From FIGS. 1 and 3 it can be seen that the end face 12 of the annular web 9 axially projects beyond the ribs 11.
  • the end face 12 of the ring web 9 serves as a flat pressing point for a pressing piston (not shown) of a press for displacing the cup base 1 in the container 2.
  • the ribs 11 are evenly distributed over the circumference of the ring web 9.
  • These radial ribs 11 result in a rigid connection of the ring web 9 to the casing wall 5, so that the ring web 9 is not deformed by the aforementioned squeezing piston when force is applied in the direction of an arrow 13.
  • the previously mentioned U-shape of the components 4 ', 5 and 9 shown in FIG. 3 together with the ribs 11 in between result in dimensionally stable cells 14 of approximately square base area (FIG. 2). It can thus be said that the cells 14 are located in the annular space between the annular web 9 and the jacket wall 5.
  • the free end face 15 of the ribs 11 is at right angles to the longitudinal axis 10.
  • the outer end face 6 of the end wall 4 consists of a radially outer planar ring part 16 and a spherical central part 17 (FIG. 1).
  • This radially outer plane ring part 16 forms the aforementioned end wall part 4 'of the U-shape 4', 5 and 9, which is located between the jacket wall 5 and the ring web 9.
  • the outer lateral surface 7 of the lateral wall 5 has three sawtooth-shaped ring beads 18, 19 and 20 connected downstream of the outer sealing lip 8. The latter also serve to seal the bowl bottom 1 on the container 2.
  • the end wall 4 enclosed by the ring web 9 is provided with an annular reinforcement web 21 which is penetrated by reinforcement ribs 22.
  • the stable cells 14 prevent the ring web 9 from deforming (bending). Even with a low pressing force 13, the right-hand turning moment mentioned with reference to FIG. 3 for expanding the sealing lip 8 is achieved, so that even low-viscosity pastes are sealed very well. Despite the relatively soft polyethylene, the aforementioned dimensionally stable cells 14 are achieved, which result in the aforementioned spreading of the sealing lip 8.
