Definitions

  • the invention relates to a device for producing and dispensing foam according to the preamble of claim 1.
  • Devices of the type mentioned are used to generate foam from a foamable liquid located in the liquid container, with the air also located in the liquid container. Foaming takes place by squeezing the liquid container, e.g. a bottle, the air and liquid displaced from the container in separate passages and fed to the mixing element being mixed into foam in the latter and conveyed to the outside. This type of foam generation avoids the use of environmentally harmful propellants.
  • the device on the market has a holding part arranged in the bottle neck of the liquid bottle, in which a conical mixer part is clamped.
  • the mixer part there are essentially coaxial passages for air and liquid to a porous mixing element and a return duct for returning air, which is also coaxial with these passages, when the pressure on the bottle is removed.
  • the mixing element spans the entire coaxial passage system, ie both the supply lines and the return duct.
  • a carrier for a cap which sits on the latter, can be switched from an open to a closed position and has an output opening communicating with a foam outlet arranged above the mixing element.
  • This known device has various disadvantages. Foam can escape between the cap carrier and the cap, soiling the outer wall of the bottle and making it difficult to handle.
  • the functionality of the bottle can only be checked after filling, so that defective bottles or devices can only be sorted out at this stage.
  • the secondary air flowing back when the bottle is depressurized leads liquid back into the bottle via the mixing element, which is then converted back into foam by the mixing element.
  • This recycled foam fills part of the air space in the bottle and impairs its functionality.
  • the known device is poorly suited for overhead removal, since a so-called wet shot with incompletely formed foam occurs at the beginning of the removal process.
  • the object of the present invention is to remedy the disadvantages of the known device. This object is solved by the features of the characterizing part of claim 1. Particularly advantageous embodiments of the invention are claimed in dependent claims 2 to 18.
  • the special design of the mounting part which can also function as a cap holder, prevents the escape of foam at an undesired location. If, in addition, the cap and the holding part are each made in one piece, both the permeability of the mixing element and the passage for secondary air flowing back, in particular the tightness of the flap valve, can be tested during assembly.
  • the device according to the invention Due to the special design of the device according to the invention, it can be assembled together in a single work step, which is both economically advantageous and technically safer.
  • a premixing chamber (s) is (are) arranged in front of the mixing element, which is particularly advantageous for devices used in an upright position, a coarse foam is formed in the premixing chamber (s), which is then further refined in the mixing element.
  • the liquid supply line ends directly at the mixing element.
  • a non-return valve in particular a flutter valve
  • the device has a second coaxially arranged supply line for liquid or air.
  • the second feed line can be arranged in a spiral or helical shape on the circumference of the holding part and can be delimited by the latter and the inner wall of the cap.
  • the container In order to avoid the sometimes cumbersome compression of the container when using it, it can be equipped with an air bellows or a pump for air or air and liquid.
  • FIGS. 1 and 2 only the neck or neck 11 of a compressible plastic bottle F can be seen.
  • An external thread 12 is formed on the outer wall of the neck 11 while the end face 13 of the neck 11 is ring-shaped and flat.
  • the internal thread 14 of a holding part 15 engages in the external thread 12.
  • the bracket part 15 to be described in more detail has a likewise annular and flat sealing surface 16 which, when the bracket part 15 is screwed on, lies sealingly against the end face 13.
  • the one-piece mounting part 15 has on its outside an external thread 17 with a high pitch, into which a corresponding internal thread 18 is flat if one-piece cap 19 engages.
  • the cap 19 to be described in more detail is shown in FIGS. 1 and 2 in the closed position and spans the entire holding part 15 in this position.
  • the holding part 15 has an axial opening 20 with a shoulder or shoulder 21.
  • a mixer part 23 is inserted in the press fit by means of a collar-ring groove snap connection 22.
  • This mixer part 23 in turn has an opening 24 ribbed on the inside in the longitudinal direction, into which the end of a tube 25 is inserted such that it is held in place by the apexes of the ribs of the opening 24. Between the outside of the tube 25 reaching to the bottom of the bottle and the inside of the opening 24, there is thus a ring of passages 26 which is coaxial with the continuous tube passage 27.
  • the mixer part 23 has on its end facing away from the tube 25 a stepped recess 28 into which a permeable mixing element 29 is inserted.
  • This mixing element 29, which - as will be described later - ensures the thorough mixing of liquid and air into foam, has a sandwich-like structure. It consists of a central part made of a coarse-mesh screen fabric that is covered on both sides by a fine-mesh screen fabric.
  • the permeability or porosity of the mixing element 29, which is an important parameter for the foam formation can be reproduced exactly.
  • mixing elements according to the prior art which usually consist of an open-pore hard foam piece made of plastic material or ceramic material.
  • the mixing element 29 is clamped in the recess 28 by the shoulder 21 of the holding part.
  • FIG. 1 Upstream of the mixing element 29 in the direction of the tube is a mixing chamber 30, into which a ring of passages 31 open, which in turn emanate from a prechamber 32 which forms the end of the opening 24. In the middle of the pre-chamber 32 there is a conical deflecting body 33 which causes the supplied air / liquid mixture to swirl.
  • the outlet 34 of the holding part 15 On the side of the mixing element 29 opposite the mixing chamber 30, the outlet 34 of the holding part 15 is formed, to which a conical sealing surface 35 adjoins.
  • this sealing surface 35 interacts with the conical outer surface of a stopper 36 which is integrally formed on the inside of the cap.
  • this sealing point is preferably arranged after the mixer part.
  • the inner extension 37 has a smooth inner surface, which rests sealingly but longitudinally displaceably on collars 39, which are formed on the outer lateral surface of the part of the holding part 15 surrounding the opening 20.
  • the outer lateral surface of the outer extension 38 is also smooth and lies in a sealing manner, but is longitudinally displaceable on an inwardly directed collar 41 which is formed on the part 42 of the holding part 15 which continues the part which carries the threads 14, 17.
  • a socket 43 is formed on the cap 19, the interior of which is divided into two channels 45 and 46 by a partition 44 formed radially on the inner extension 37.
  • the channel 45 is - when the cap 19 is in the open position - only in connection with the outlet 34, while the channel 46 with the jacket space 47 'between the inner and outer extension 37 and 38 respectively.
  • a sealing surface 47 is formed, which cooperates with an oppositely shaped sealing surface 48 on the section of the holding part 15 connecting the part 42 to the part 40.
  • This sealing surface 47 is preferably arranged in the immediate vicinity of the membrane 50.
  • this section there is also a ring of passages 49, the purpose of which will be described below.
  • annular flexible membrane 50 is formed on the end of the mixer part 23 facing away from the mixing element 29.
  • This membrane 50 forms the closing part of a check valve, which closes the passages 49 when there is excess pressure in the bottle. It is attached by means of a hinge, which means that it cannot malfunction as a result of tilting.
  • the plug 36 separate from the sealing surface 35 and the sealing surfaces 47 and 48 from each other.
  • the channel 45 communicates with the outlet 34 and, on the other hand, the channel 46 via the jacket space 47 'with the passages 49.
  • the membrane 50 closes the passages 49, liquid rises in the tube 25 up and air is displaced from the air cushion above the liquid level in the bottle through the passages 26.
  • the fluid flow and the air flow meet in the antechamber 32, supported by the displacement body 33, already mix there and this mixture (coarse foam) passes through the passages 31 into the mixing chamber 30. From there, the mixture is pressed through the mixing element and leaves it as Foam that then exits channel 45 via outlet 34.
  • the membrane 50 opens the passages 49 and outside air can flow back relatively freely through the channel 46, the jacket space 47 'and the passages 49. It should be noted here that small amounts of any foam still present at the outer end of the channel 45 are sucked in from the outer end of the channel 46 and flows back into the bottle F in the same way, where it comes into contact with the liquid within a short time disintegrates. Air can also flow back through the channel 45, but the air on this way back is opposed by flow-restricting or restricting obstacles (mixing element 29, passages 26), so that the The amount of air flowing back through channel 45 is significantly smaller than that from channel 46.
  • the embodiment shown in Figure 2 is for overhead delivery of foam, i.e. the neck of bottle F points downwards.
  • the pre-chamber 32 and the mixing chamber 30 are therefore dispensed with and only the foam-forming liquid flows through the passages 31 when in use.
  • the plug 36 In the open position of the cap 19, the plug 36 also separates from the sealing surface 35 and the sealing surfaces 47 and 48 from one another.
  • Channel 45/46 combined here thus communicates on the one hand with outlet 34 and on the other hand with passage 49.
  • the mixer section 23 shown in FIGS. 3 and 4 is preferably suitable for foam formation and delivery from an upright bottle. Since it is partly designed analogously to that in FIG. 1, which was described in detail above, parts already described in FIG. 1 are provided with the reference numbers used there.
  • the tube 25 is held, which opens into the stepped narrowed continuation 24 'of the opening 24.
  • the latter is connected to the mixing chamber 30 at its end facing the mixing element 29 by means of radially arranged openings.
  • the passages 26 end at 61.
  • the mixer part 23 has one or more radial openings 63 in the area of the passages 26. Subsequently, there are helical feed lines 64 on the outer wall of the mixer part 23, which lead into the mixing chamber 30 in the form of radial passages 65.
  • These helical feed lines 64 enable the mixing process to be improved and the mixing ratio to be kept constant.
  • the mixer part 23 shown in FIG. 5 is preferably suitable for foam formation and foam dispensing overhead.
  • the parts described in connection with FIGS. 1 and 3 are identified by the same reference numerals.
  • the reduced narrowed continuation 24 'of the opening 24 ends directly on the mixing element 29.
  • the helical feed lines 64 end via radial passages 65 in the pre-chambers 30' upstream of the mixing element 29 in the flow direction. It follows from this arrangement that in this case the mixing only takes place in the mixing element 29. In this case too, the helical shape of the one feeder achieves an improved mixing ratio.
  • FIG. 6 corresponds approximately to that of FIG. 1, but is simplified in various respects.
  • the holding part 15 is not screwed onto the external thread 12 on the connection piece 11 as in FIG. 1, but with an annular, inward facing ten, molded cams 53 engages behind a corresponding outwardly projecting cam 54 on the nozzle 11.
  • the tight and sealing against the end face 13 of the socket sealing surface 16 of the mounting part has the shape of an annular lip.
  • the outlet 34 from the holding part 15 does not run axially here as in FIG. 1, but rather radially, so that the foam emerging from the mixing element 29 is first thrown against a jacket-shaped wall before it finds its way past the plug 36 to the discharge channel 45.
  • the outlet 34 is formed here in a coaxial dome 56 molded onto the mounting part 15. As can be seen from FIG. 6, the plug 36 penetrates into the intermediate space 57 between the outer wall of the dome 57 and the jacket wall 55 in the closed position and thus forms a tight seal.
  • the foam leaving the mixing element 29 flows again through the radial outlet 34 in the dome 56, then hits the jacket wall 55 and then leaves the cap 19 through the central outlet channel 45 outside the foam is compressed and expanded several times, which contributes to an improvement in the foam quality.
  • the liquid-air mixing process in the mixer part 23 and in the mixing element is not particularly intensive, as already mentioned, a so-called "wet shot", i.e. a jet of liquid mixed with little air. Thanks to the wall 55, however, this liquid does not flow or hardly flow out through the channel 45, but collects in the annular space 52 between the outside of the plug 36 and the inner wall of the extension 37 formed on the cap 19.
  • the bottle F When the foam removal via the head has ended, the bottle F is again placed upright, and it reverts to its original shape. This creates a negative pressure in the bottle. With the cap still open, outside air now flows in through the opening 46, which is formed on the side of the outlet duct 45 (bottom right in FIG. 7) the annular space 58 surrounding the extension 37 and from there through the gap between the outside of the extension 37 and the raised sealing surface 47 (left in FIG. 7) and through the passages 49 now released by the flat membrane 50 back into the bottle F. until pressure equalization is restored.
  • the neck or neck 11 of a compressible plastic bottle F In the device 10 shown in FIG. 8, one can see, as in FIGS. 1 and 2, the neck or neck 11 of a compressible plastic bottle F.
  • An external thread 12 is formed on the outer wall of the neck 11, while the end face 13 of the neck 11 is ring-shaped and flat.
  • the internal thread 71 of a cap 72 engages in the external thread 12.
  • the cap 72 In addition to the external thread 12, the cap 72 is supported on a holding part 73.
  • the holding part 73 is held on the nozzle 11 by means of a snap lock 75 of a known type. It also has a ring-shaped and flat sealing surface 74 which bears sealingly against the end face 13.
  • This mounting part 73 has a low overall height, which allows greater dimensional accuracy during manufacture.
  • the one-piece mounting part 73 has on its upper circumference a shoulder 76 which engages in a corresponding recess 77 in the closed position of the cap 72.
  • the cap 72 is shown on the left in the closed position and on the right in the open position and spans the holding part 73.
  • a mixer part 79 is held coaxially on the holding part 73 in the bottle by means of a snap closure 81, the sealing surfaces 92, 93 forming the outer wall of the Holding part 73 and the inner wall of the mixer part are conical, which results in an improved sealing property.
  • the mixer part 79 has an opening 82 ribbed on the inside in the longitudinal direction, into which the end of a pipe 83 is inserted such that it is held in the opening 82 by the ribs 84.
  • a ring of passages 85 thus arises between the outside of the tube 83 reaching approximately to the bottom of the bottle and the inside of the opening 82.
  • the holding part 73 has an opening 82 in the mixer part communicating and with the latter coaxial opening 86 and on the front side facing the mixer part 79 a stepped recess 88 into which a mixing element 87 is inserted and held by a press lip 89 of the mixer part.
  • the mixing element 87 corresponds to that which has been shown and described in the preceding figures. Mixing chamber 30 and prechamber 32 were also shown and described there.
  • an elongated, conical deflecting body 91 is arranged here, which protrudes into the tube 83, as a result of which its free cross section is reduced. During operation, this causes the liquid flow to accelerate before being mixed with air, which improves foam formation. This advantage is of particular importance in the case of a bottle that has already been partially emptied, particularly in the case of a bottle that is largely empty.
  • cap 72 essentially corresponds to that in FIG. 1. Differences exist to the extent that this requires the design of the shorter and simpler mounting part.
  • the cap 95 is shown in the closed position.
  • the head part 96 of the cap 95 is hinged to the lower part 98 of the cap 95 with two joints 97 (only one of which is shown).
