Definitions

  • the invention relates to a dispenser for foaming a liquid filling material according to the preamble of claim 1 (cf. US-A-4836 422).
  • Dispensers in which an air / filling material mixture is foamed by means of an additional sieve attachment are widely known.
  • DE-C-29 25 528 a device with a hand pump.
  • the problem can arise that the re-expansion of the compressible container that is required after the dispenser is actuated takes place too slowly.
  • the sieve offers great resistance to the inflowing air, especially if it is wetted with a viscous filling material or is partially blocked due to prolonged use.
  • the container must be made stiffer so that it reliably expands again.
  • the strainer As a flow valve.
  • the sieve is held so loosely in the outlet duct that when the container is pressed together it is pressed against a shoulder of the outlet duct and completely covers the latter, while the sieve is held under the suction effect in such a way that part of the air flowing back bypasses the sieve directly into the mixing chamber.
  • foam dispensers are described for example in US-A-3,709,437 and in US-A-4,836,422.
  • this object is achieved with a dispenser having the features in claim 1.
  • the air flowing back can flow into the interior of the container without great resistance and the container is immediately ready for a new spraying process.
  • the refilling process with air can be further accelerated in that the outlet channel is connected to the interior of the container via an aeration channel and that the sieve has a closure body which closes the aeration channel when the outlet channel is covered and releases the aeration channel when the outlet channel is partially exposed.
  • the screen also has a kind of valve function, the valve actuation being effected by the negative pressure or the excess pressure in the outlet channel.
  • a common mixing chamber in front of the mixing nozzle ensures optimal swirling of the filling material with the expelled air, regardless of which of the two channels the filling material is introduced into the mixing chamber. Both channels can easily open tangentially into the mixing chamber. However, it is also possible for one of the two channels to open into the mixing chamber coaxially with the mixing nozzle.
  • the second channel is provided with a valve which, when the container is overhead, completely or partially closes the second channel.
  • This valve could also be arranged completely independently of whether the two channels open into a common mixing chamber. If the valve closes the second channel only partially, it acts as a throttle valve, so that the ratio of air to product to be filled can be maintained.
  • valve in the overhead position may also be desirable for the valve in the overhead position to completely close the second channel, so that even when the container is pressed together, no filling material can be ejected.
  • the valve can particularly advantageously have a valve body which is freely movable in a cage-like holder and which, when it is upside down, rests against a valve seat.
  • the cage-like holder can be easily integrated into the spray head and, for example, a ball can be used as the valve body.
  • FIGS. 1-3 An embodiment of a dispenser according to the invention is shown in FIGS. 1-3.
  • a compressible container e.g. made of plastic material
  • a cap 2 is firmly connected.
  • This cap contains a spray insert 4, in which an approximately circular cross-section mixing chamber 8 and a conical mixture nozzle 7 are arranged.
  • a first channel 15 and a second channel 9 lead from the inside of the container to this mixing chamber.
  • a riser pipe 3 is fastened, which, as can be seen from FIG. 4, is immersed in the filling material 31 in the upright container position.
  • the connecting piece 16 forms the end of the first channel 15 on the container side. This channel opens tangentially into the mixing chamber 8, as can be seen from FIG. 3.
  • the second channel 9 leads on the container side to a valve which is formed by a cage-like holder 14, a ball 13 and a valve seat 10.
  • the holder 14 is plugged onto the socket 16 and has lateral webs 12, between which the valve ball 13 made of metal, plastic or ceramic is held.
  • the height of the webs 12 is limited such that the openings between them and the cap 2 11 remain.
  • the channels 18 run, which connect the interior of the container or the air space 33 above the filling material to the second channel 9 via the openings 11.
  • the second channel 9 opens coaxially with the mixing nozzle 7 into the mixing chamber 8.
  • the conical valve seat 10 is designed such that it completely closes the channel 9 when the valve ball 13 is in contact.
  • the valve seat can also be provided with a number of fine radial grooves, so that the valve only acts as a throttle valve and the flow rate is reduced when the ball is in contact.
  • the mixture nozzle 7 opens into an outlet channel 19 which, when a foamable liquid is used, is provided with a movable sieve 6 which is arranged at a distance from the mixture nozzle.
  • the outlet channel 19 can be closed with a hinged cover 5 which is attached to the spray insert 4 in a hinge-like manner.
  • the hinged lid 5 in particular prevents the screen 6 from drying and sticking.
  • the filling material 31 flows through the riser pipe 3 and the first channel 15 into the mixing chamber 8 due to the increased internal pressure.
  • air from the air space 33 passes through the channels 18, the openings 11 and the second channel 9 into the mixing chamber 8.
  • the first channel 15 leads tangentially into the mixing chamber, as a result of which the inflowing liquid is set in rotation and thus mixes with the air flow supplied centrally via the second channel 9.
  • This air-liquid mixture is accelerated through the conical mixture nozzle 7 to the outside of the container and released as a spray. When the sieve 6 is inserted, this mixture is foamed.
  • the valve In the normal container position shown in Figure 4, the valve is not effective.
  • the air can flow freely into the mixing chamber 8 without the ball 13 changing its position within the holder 14 and influencing the air flow.
  • the ratio of air to liquid is determined solely by the smallest cross sections of the channels 9 and 15.
  • the riser pipe 3 projects into the air space 33, so that the media in the channels exchange in this position.
  • the air now arrives tangentially into the mixing chamber 8 via the riser pipe 3 and the first channel 15.
  • the filling material is fed into the mixing chamber via the channels 18, the openings 11 and the second channel 9, where it mixes with the air flow now set in rotation becomes.
  • FIGS. 6 and 7 show a second embodiment of the dispenser according to the invention.
  • the valve also consists here of a holder 14 provided with the webs 12 and the slot-shaped openings 11, which is in the form of a cylindrical Cage is formed in which the ball is held freely. The blocking or reduction of the liquid flow in the overhead position is achieved with a corresponding change in the position of the ball 13, which rests on the either polished or uneven valve surface 10 and closes the channel 9 'completely or partially.
  • the optional use of the central inlet according to FIGS. 1 to 3 or tangential inlet according to FIG. 6 is advantageous.
  • FIG. 8 shows a third embodiment of the dispenser according to the invention with the container in an upright position and in the open state. This shape is particularly easy to close due to the rotatable spout attachment 20.
  • FIG. 6 shows an embodiment with two tangential inlets as shown analogous to FIG. 6, a central inlet analogous to FIG. 2 could equally well be used.
  • the valve device described above is not shown here for the sake of simplicity.
  • a cap 2 is firmly connected to a container 1, the cap carrying a spout attachment 20 which can be pivoted about the cap axis, the inner wall of which lies in front of the sealing insert 21 in the closed state and thus closes the dispenser.
  • the cap 2 contains the spray insert 4 and the sealing insert 21 between which the sieve 6 is only attached on one side.
  • the sieve Since the sieve is designed to be flexible, the unsecured underside is moved in the direction of the interior of the container by this air flow and reaches approximately a position 6 '. Between the sieve in position 6 'and the spray insert 4, an air gap 23 opens, through which part of the inflowing air can enter the container unhindered and without having to pass through the sieve. Particularly when using fine-mesh sieves, the re-expansion of the container is hereby significantly accelerated. This means that softer containers can be used from the outset, which makes it much easier to operate the dispenser.
  • the sieve 6, which is made, for example, of plastic fabric, is movable because it is held between the spray insert 4 and the sealing insert 21 only at its upper edge.
  • the flexible fabric deforms in the inflowing air flow in such a way that it is flowed around laterally and below in position 6 '.
  • a rigid sieve for example made of metal mesh, can also be movably supported by being injection-molded onto one side of a thin plastic tab - a so-called film hinge - or by means of ultrasound welding.
  • FIG. 9 Such a rigid screen with a film hinge 25 is shown in FIG. 9, for example.
  • the back-flowing air reaches the interior of the container even more quickly via a ventilation duct 28.
  • This ventilation channel connects the air space 33 in the container directly to the outlet channel 19.
  • the sieve 6 has at its freely movable lower edge a cover 29 which closes the ventilation channel 28 when the air / filling material mixture flows out.
  • the open position with exposed ventilation duct 28 is interrupted Lines shown.
