Definitions

  • the present invention relates to a method for the portionwise generation of foam from liquid soap according to the preamble of patent claim 1.
  • the invention further relates to a device for the generation of portions of foam from liquid soap according to the preamble of claim 3.
  • Soap dispensers are known in practice, in particular for toilets and washrooms in public buildings and restaurants, in which a measured portion of liquid soap is dispensed into the hand by actuating a pivoting lever.
  • the disadvantage of these soap dispensers is that they tend to drip, i.e. that, over time, soap collects below the soap dispenser on the washing trough or on the floor, which must be removed.
  • a foam dispenser is known from GB-A-2193904 mentioned in the European search report, which is placed on a storage bottle with liquid soap.
  • An intermediate container is inserted into the storage bottle from above and a first dip tube, which is fastened to the underside of the intermediate container, projects into the storage container.
  • a non-return valve is placed on the upper end of the first immersion tube, which prevents soap from flowing back from the higher intermediate container into the storage container underneath.
  • a double-acting pump which is also placed on the storage container, air can be introduced into the head space above the soap in the intermediate container and also extracted from it. The air for foam generation is fed through a tube that is immersed in the soap Intermediate tank initiated.
  • a second immersion tube at the upper end of which a foam generator sits, protrudes from above into the intermediate container and extends almost to the bottom.
  • the foam dispenser arranged on the second immersion tube, is connected to the dispenser tube for dispensing the foam.
  • the intermediate container should be emptied with every pump stroke and refilled with the suction stroke of the pump.
  • To create a portion of foam air is pressed into the intermediate container and, as a result of the increased pressure on the soap surface, soap is pressed from below through the second immersion tube and air from the side into the foamer head and mixed into foam there.
  • a vacuum is created in the intermediate container, which causes soap to be sucked up into the intermediate container from the storage bottle with a vent line at the top.
  • the amount of soap soaked depends on both the current level in the storage bottle, the prevailing atmospheric pressure and the viscosity of the soap. These three variable sizes, which in turn are influenced by further parameters (eg temperature), result in an always undefined and non-constant amount of foam and in particular foam density (air / soap ratio). As a result, the consistency of the foam is usually unsatisfactory because an acceptable result can only be achieved with a precisely coordinated soap / air mixture.
  • Another disadvantage of this known device is that when the excess pressure is generated in the intermediate container, foam bubbles can be formed on the soap surface by the immersed air supply tube, which foam bubbles influence the amount of soap stored in the intermediate container. Ultimately, this causes a non-reproducible, technically unmanageable mixing ratio of air and soap in the foamer.
  • a foam dispenser with a storage and an intermediate container is also known. Air is introduced into the intermediate container through an air supply line, and soap and air are pressed into the foamer and foam is produced. After completion of the pressure build-up can flow of soap from the storage container into the intermediate container from below through a diaphragm valve. The amount flowing in depends - as with GB-A-2193904 - at least on the fill level in the storage container, the atmospheric pressure and the viscosity of the soap. The generation of foam with constant properties is not guaranteed.
  • a device for dispensing cleaning agents in which the storage container is arranged above an intermediate container, so that the soap can flow according to consumption.
  • the soap is removed from the intermediate container by means of a horizontally displaceable metering piston.
  • the amount removed can vary due to the changing viscosity and unavoidable deposits in an uncontrollable range, so that foams of different consistency (density) are produced with the same amount of air.
  • a device for metering and forming soap foam in which the piston of a soap solution metering pump can be moved back and forth with the actuating lever and at the same time is connected to a device for generating compressed air .
  • the actuation lever is connected to the elements to be actuated (piston and device for generating compressed air) at least with respect to the piston via articulated members which convert the arcuate course of the drive pins into a linear movement. Additional link members cause higher manufacturing and assembly costs and are more susceptible to defects such as undivided, direct-acting lever arrangements.
  • the invention is based on the object of providing a method and a device in which, regardless of the filling level of the soap container, an equal amount of foam with properties which can be determined in advance can always be produced.
  • the interposition of an expansion and a metering container in which a defined amount of soap and air always flows after each pump stroke, keeps the consistency and the amount of foam constant.
  • the amount of soap and air in the expansion tank can be changed and thus the ratio between air and soap in the foam and adjusted to the soap quality and viscosity used.
  • a tube arranged in the expansion tank enables easy assembly and - if necessary - replacement of the foamer and allows foam residues to be sucked back or blown off at the dispenser opening at the end of the dispensing process and to prevent dripping.
  • the head space above the soap can be easily, e.g. be kept constant within very narrow limits by the immersed tube from the storage container.
  • the foam dispensing device 1 shown in Figure 1 is housed in a housing 3, which can be attached to a wall 5 and consists of plastic or sheet metal.
  • a storage container 7 is accommodated with a nozzle 9 attached to its base 8, which is connected to an expansion tank 13 via a connecting line 11.
  • the line 11 dips from above through an opening 15 into the expansion tank 13 by the amount X. If desired, the line 11 can be telescopic in order to make the immersion depth X adjustable (indicated by broken lines).
  • the lower end of line 11 is closed by a membrane valve 12, which, on the one hand, permits the entry of liquid soap 27 from the storage container into the expansion tank 13, but, when the expansion tank 13 is pressurized, does not allow liquid soap to escape from the expansion tank 13 into the storage container 7.
  • the configuration of the valve 12 is not described in detail, since such valves are sufficiently known from the prior art.
  • the foamer 21 consists of a soap supply pipe 16, the upper end of which has a central opening or a large number of fine bores 18.
  • a fine-pored sieve or sintered plate 20 lies above the bores 18 and at a distance from them.
  • the upper end of the jacket of the line 16 has fine bores 22 which are in connection with the interior of the expansion tank 13.
  • the annular space outside the fine sieve 20 is spanned by an annular membrane seal 24, which only allows air to escape through the fine sieve 20 when there is excess pressure in the expansion tank 13, but allows air to enter the head space 45 when there is negative pressure inside.
  • the expansion tank 13 is further connected by a line 36 to a bellows 35 acting as a pump.
  • a translation lever 41 engages on the bellows 35 and is mounted on the housing 3 so as to be pivotable about an axis B.
  • An actuating lever 39 which projects out of the housing 3 at the bottom, is pivotable about an axis A and is articulated to the transmission lever 41 by a second axis C.
  • a return spring 47 is inserted which returns the bellows 35 to the starting position when there is no force F on the actuating lever 39.
  • the spring 47 can of course also engage one of the levers 39 or 41.
  • the valve 12 on the nozzle 9 is closed.
  • the pressure p1 in the expansion tank 13 drops since the actuating lever 39 returns to the starting position and air can enter the head space 45 through the opening membrane seal 24. Air can flow back through the line 36 into the bellows 5 and fill it up again.
  • liquid soap flows through the nozzle 9 out of the storage tank 7 through the valve 12 into the expansion tank 13 until the amount of soap squeezed out during foaming is replaced.
  • the level h2 is determined by the immersion depth x of the connecting line 11.
  • a corresponding valve can also be used at another location of the expansion tank 13.
  • the foam dispensing tube 26 can also be surrounded by a jacket 28 through which the air is sucked back into the bellows 35. Any remaining foam at the end of the tube 26 can be sucked back into the expansion tank.
  • a plate, step angular or star-shaped lever 50 (indicated by dash-dotted lines in Figure 4), which is pivotally mounted about the axis A to the side of the pump 35.
  • the stroke when the pump 35 is actuated thereby becomes somewhat smaller. This can be compensated for by a correspondingly larger bellows.
  • a foam dispensing device 101 is shown with a housing 103 which is attached to a wall 105.
  • a storage container 107 is accommodated with a socket 109 attached to its base 108 and connected to a compensating container 113 via a connecting line 111.
  • the line 111 dips into the expansion tank 113 from above through an opening 115.
  • a tubular recess 161 which projects into the expansion tank 113, there is a tube 117, on the bottom 162 of which a valve 163 is arranged.
  • a second pipe 116 the lower end of which is open and the foamer 121 is placed on the upper end, projects into the first pipe 117.
  • An O-ring 165 can be used to seal the tube 117 with respect to the tubular recess 161.
  • the tube 117 forms a metering reservoir or container 110 with a volume which is substantially smaller than that of the expansion tank 113.
  • a bellows pump 135 is placed over the storage container 107 and is articulated by a lever or linkage 141 to a two-armed actuating lever 139.
  • the operating lever 139 and the two-armed lever 141 can also be connected to one another by a spring 144 inserted between the articulated connection point 142 and the end 146 of a shortened lever 141.
  • the spring 144 is designed to progressively build up the force on the bellows 135 when the actuation lever 139 is operated (pivoting counterclockwise) by tensioning the spring 144 and to continue to compress the bellows 135 even after the pivoting movement of the actuation lever 139 has ended.
  • a spring 147 is intended, after the actuation lever 139 has been pivoted and thus after the bellows 135 has been compressed, to move the bellows 135 back into the starting position and to fill it with air.
  • a connecting line 136 leads from the bellows 135 to the head of the foamer 121, which is surrounded by a housing 169.
  • the foamer 121 is inserted into the end of the tube 117.
  • a dip tube 116 open at the bottom leads from the foamer 121 to close to the lower entrance of the tube 117.
  • the upper end of the tube 116 ends under the fine bores 118 in the foamer 121 and opens at a distance from a fine-meshed sieve 120.
  • Above the sieve 120 and in contact with the latter begins a foam dispensing line 126, from the end of which the foam S is dispensed onto the hand.
  • Fine channels 122 at the upper end of the dip tube 116 lead into the space between the bores 118 and the soap surface in the tube 117.
  • the tube 117 is connected at the top via a valve 146 to the line 136 with the bellows 135.
  • the foam dispensing tube 126 leads through an intermediate wall 167 within the housing 169.
  • the interior of the housing 169 is also connected to the line 136 by a first diaphragm valve 171.
  • a collection space 172 for the liquefaction of sucked-back foam S can be provided between the valves 146 and 171.
  • the foam dispensing device 101 in the embodiment according to FIGS. 2 and 3 works as follows. After the storage container 107 has been inserted, liquid soap 127 flows through the nozzle 109 into the expansion tank 113 until a level of h2 is reached. Through the valve 163, the liquid soap can also enter the tube 117 from below and also fill it up to the height h2. By pulling the actuating lever 139, the pump designed as bellows 135 is compressed via the linkage 141 and at the same time the return spring 147 curious; excited. In order to obtain the largest possible amount of air with a short pump stroke, two bellows pumps 135 can also be arranged side by side in parallel.
  • the expanding bellows 135 draws air through the line 136 through the valve 171 from the space between the pipe 126 and the housing 169 and at the same time draws air from the environment at the end of the pipe 126. Any foam residue left there is sucked back into the foamer 121 and can return to the pipe 117 the next time air is applied through the valve 146.
  • the bellows 135, which is located at the highest point of the device, will in no way become liquid soap sucked up, and no pollution can occur. Furthermore, the described manner of recycling foam residues prevents foaming of the liquid soap 127 in the expansion tank 113.

  • the bellows are filled by valves 240.
  • the expansion tank 213 is connected to a storage tank 207 by a line 209.
  • a check valve 212 is also attached to the end of the line 209, which prevents the liquid soap 227 from flowing back into the container 207 when the pressure in the head space 245 is built up by the two bellows 235.
  • a foamer 221, as has been described in FIG. 1, is inserted in a pipe socket 217.
  • a dip tube 216 attached to it dips into the liquid soap 227.
  • the foam dispensing tube 226 begins above the foamer 221 and ends at the front of the housing 203.
  • a line 281 leads from the bellows 235 'to the end of the donor tube 226.
