Definitions

  • the invention relates to a dispenser according to the features of the preamble of claim 1.
  • Such donors have become known in a variety of forms. They serve in particular as a toothpaste dispenser, but also, for example, as a dispenser for mayonnaise, ketchup or the like.
  • the object of the invention is to make a dispenser of the generic type, in particular, for example, such as is known from DE-OS 31 04 726, more advantageous in use.
  • a dispenser for portioned delivery of its contents, in particular pasty mass which has a piston which can be displaced step by step in the direction of emptying and an actuating handle which can be displaced counter to spring force.
  • the outlet opening of the dispensing tube can be closed by means of a closure part molded onto the actuating handle.
  • the invention provides a circumferential groove in the outer wall of the dispensing tube, immediately in front of the outlet opening, which groove forms a sealing lip. It is too It is advantageous to form on the side of the closure part facing the outlet opening of the discharge tube a raised closure base which projects into the interior of the discharge tube in the region of the sealing lip in the closure state.
  • the closure base represents, as it were, a stopper with a low height.
  • the outlet cross section of the outlet opening is an inclined surface such that a lower edge section of the outlet opening is opposite one upper edge portion of the outlet opening is set back.
  • the outlet opening could also be formed with a curved surface, an edge section of the outlet opening being essential, which enables the closure part to be positively engaged.
  • a pump chamber is formed in the dispenser, which has a cylindrical region which is formed by a wall fixed to the housing. In the cylindrical region of the pump chamber, the dispensing tube is guided so that it can move axially. A tube extension extending into the storage space is formed in the lower end wall of the pump chamber.
  • the tube extension can be covered on the pump chamber side by a closure cover, which closure stop is held in the tube extension so as to be axially movable in a manner limited by stops.
  • the holder is realized by means of holder and guide webs which extend in the tube extension and have barb-like configurations at their ends.
  • the pump chamber has separate passage openings, while the first mass can be conveyed into the pump chamber through the lid-closable extension.
  • the passage openings for the second mass can only be partially covered by the closure cover, which can cover the tube extension completely. Even when the tube extension is closed by the closure cap, the through openings for the second mass are partially open. There is therefore an unclosable, permanent connection to the pump chamber for the second mass.
  • the passage openings for the second mass open into grooves which are formed in the bottom section of the pumping chamber, which is funnel-shaped overall.
  • the grooves are partially covered in the closed state by the cover.
  • the closure lid is partially funnel-shaped on its underside, but has no elevation corresponding to the grooves, so that in the closed state it forms an upper boundary of the grooves only for those areas of the grooves which it covers.
  • the grooves are designed to run radially.
  • This configuration is associated with the advantage that during the closing movement and the closing position of the closing cap which occur due to the pumping process, the second mass is only partially pressed into the grooves. However, the strands of second mass flowing through the grooves cannot be completely separated off or pressed flatly.
  • the pasty mass of the first type flows through the tube extension and then past the edge of the sealing cover under deflection, while the pasty mass of the second type practically only flows in the formed grooves in this area.
  • the closure cap for the tube extension remains in its raised position. In the idle state, there is therefore a constant moisture connection of the pump chamber to the storage space not only for the pasty mass of the second type, but also for the pasty mass of the first type.
  • any backstop can be dispensed with, despite the constantly open through openings for the second mass in the pumping chamber, since the closure cover connects the pumping chamber to the storage space, if not completely. keeps it tight enough.
  • a dispenser generally designated 1 for portioned dispensing of pasty mass which in a known manner has a cylindrical housing 2 and in which the dispenser head 3 is covered with a cap 4 in FIG. 1.
  • a piston 5, which can be displaced step by step in the emptying direction is arranged in the cylindrical housing 2.
  • the dispenser head 3 has an actuating handle 6 and a dispensing tube 7.
  • the dispensing tube 7 is axially displaceable in the actuating handle 6, as in a cylindrical region 8 of the pump chamber 9 which is fixed to the housing.
  • the dispensing tube 7 has an outer, circumferential groove 12 near the outlet opening 11, through which a sealing lip 13 is formed. In the closed state according to FIG. 1 or FIG. 5, the sealing lip 13 lies sealingly on the inside of the closure part 10. Because the dispensing tube 7 is dragged from a dispensing position according to FIG. 3 into a rest position according to FIG. 5 or FIG. 1, with a form-fitting interaction, there is a very tight fit of the closure part 10 against the outlet opening 11, especially since Weight, which is to be raised during the return movement via the closure part 10, is relatively large, namely the dispensing tube 7 and, in particular, the paste-like mass thus raised at the same time.
  • a raised closure base 14 can be formed on the inside of the closure part 11, as can be seen in particular in FIGS. 2 and 3, which protrudes into the interior of the dispensing tube 7 in the region of the sealing lip 13 in the closed state if only a little.
  • the outlet cross section of the outlet opening 11 of the dispensing tube 7 is designed as an inclined surface, such that a lower edge section 15 of the outlet opening 11 is set back relative to an upper edge section 16 of the outlet opening.
  • the closure part 10 is formed accordingly inclined, which results in the positive cohesion in the closed state.
