Definitions

  • the invention relates to a dispensing device for liquid or pasty goods, such as disinfectants and cleaning agents, soap and ointments, which essentially consist of a wall mounting, a cover connected to the wall mounting, means for locking the cover, an output container for the goods to be dispensed with the Wall mounting is detachably connected, a pump and metering device connected to the dispensing container with an inlet and an outlet valve, means for holding and opening a storage container for the goods to be dispensed, and an actuating handle mounted on the dispensing container for the dispensing goods.
  • a dispensing device for liquid or pasty goods such as disinfectants and cleaning agents, soap and ointments
  • Dispensers of the aforementioned type are known as such and are widely used as soap dispensers. The invention is therefore described below using the example of a soap dispenser, without being limited thereto.
  • a major problem with conventional soap dispensers is the need for the greatest possible hygiene. This does not only mean that the soap dispenser as such can be kept clean with the simplest possible means and with little effort, it is also essential that the operating elements, ie the handle that must be touched by the user, are easy to clean. In many cases, if the handle is designed as a more or less vertically hanging lever as usual, the user has to grasp this lever from behind and pull it forward to remove soap from the dispenser. Soiling occurs right at the rear of the lever, where it cannot be seen and therefore cannot be removed by most people who have to maintain and clean the container.
  • the object of the present invention is therefore to prevent unwanted leakage of soap at uncontrolled times while at the same time creating a device which withstands higher hygienic requirements and is easier to clean.
  • the distance between the dispenser nozzle of the soap dispenser and the actuating device should be designed such that the soap is dispensed onto the palm of the hand and not between the fingers, in order to prevent soap from dripping onto the floor.
  • a dispensing device for liquid or pasty goods such as disinfectants and cleaning agents, soap and ointments
  • a dispensing device for liquid or pasty goods which essentially consist of a wall fastening, a cover hood connected to the wall fastening, means for locking the cover hood, a dispensing container for the goods to be dispensed, which is detachably connected to the wall mounting, a pumping and metering device connected to the dispensing container with an inlet and an outlet valve, means for holding and opening a storage container for the goods to be dispensed, and one stored on the dispensing container for the dispensing goods
  • the dispensing container carries a module on its base within a U-shaped profile, into which a pump is integrated, the module is connected to the interior of the container via an inlet valve, a relief channel and a compensating bore, the U- shaped profile on its legs in the area of the web bearing holes for receiving stub axles of the actuating lever and the actu
  • the space in which the pump and dispensing opening are arranged is open and can be reached from below with dirty fingers.
  • the object of the application has the advantage that this space is covered by a cover plate, which is arranged on the actuating lever for the pump, so that the actuating handle extends outward as an integral part under the cover plate.
  • This arrangement enables the use of a stable handle that runs parallel to the bottom of the soap dispenser, that is, parallel to the cover plate, and thus allows the finders to be gripped around. Since its narrow side faces the back wall, the mostly dirty front limbs of the fingers come onto the inside of the handle, where the dirt marks can be seen and removed from the front.
  • the pump as such is integrated in a module which is connected to the interior of the container via an inlet valve and a compensating bore.
  • the handle is provided with spring-mounted articulated levers which carry stub axles.
  • the articulated levers which extend perpendicular to the cover plate, are, like the stub axle, an integral part of the handle, i.e. that they are made as a molded part from one and the same plastic. By separating it from the cover plate, it can also serve as a stop against the web of the U-shaped profile or the wall fastening and hold the cover plate essentially in a horizontal position.
  • the articulated levers it is possible for the articulated levers to be pressed resiliently inward due to the free space arranged between the cover plate and the articulated lever in order to insert the stub axles which project outward into the bearing bores of the legs.
  • there is not only a simpler construction which in turn leads to less expensive production, in particular additionally by eliminating axes, screws and other fastening means. It also has a smooth surface that is much easier to clean and therefore more hygienic.
  • An expedient embodiment provides that the handle is connected to the cover plate via spacers.
  • This embodiment is chosen in particular when the soap dispenser is arranged in rooms where special hygiene is required, for example in operating rooms or the sterile rooms assigned to them.
  • the operator must not touch the non-sterile handle of the dispenser with his hands, which must remain or must become sterile - instead of soap, a disinfectant can be removed from the dispenser.
  • the handle protrudes far beyond the dimensions of the dispenser, ie in the direction of the operator, so that it can be operated with the arm on the hand of which the soap is to be dosed, that is to say that one-hand operation also takes place in this case.
  • a particularly advantageous embodiment of the invention indicates that the cover plate is provided with a stop screw.
  • This stop screw is located in the front area of the cover plate and is expediently designed as a grub screw so that it does not protrude downward into the handle area.
  • the arrangement in the front area of the cover plate ensures that the membrane is unloaded in the idle state.
  • the path of the actuating lever can be regulated, which automatically results in a change in the stroke of the pump and thus a change in the amount of liquid soap to be dispensed, since the grub screw attaches to the housing into which the pump is integrated, strikes.
  • the pump is a diaphragm pump, which is connected to the outlet valve and the relief channel via a pump channel.
  • the cover plate is expediently provided with a pressure cushion.
  • the pump diaphragm is advantageously designed as a cup diaphragm with a reinforced center, so that it is practically not subject to wear. This reduction in wear is further supported by the pressure pad on the cover plate, which presses on the pump membrane.
  • the pressure pad expediently has a curved surface, for example in the form of a cylinder with rounded edges of the end face, as a result of which the shape of the pressure pad does not cause any sharp-edged deformation of the pump membrane, which in turn reduces wear and increases the service life of the unit.
  • the connection of the pump to the relief channel is of particular importance.
  • the relief channel extends from the pump into the interior of the dispensing container and ends here with at least one opening which is covered by the storage container.
  • the discharge channel ends at a different location for the cleaning agent dispensing container than for Disinfectant dispenser.
  • the associated storage containers also differ in their design, that is to say that a storage container which does not contain the correct good can still be inserted into the dispensing container of the dispensing device, but then no longer closes the relief channel.
  • the outlet valve consists of a spring-loaded valve body with a conical valve body tip, which engages in a valve cap with a nozzle bore.
  • the valve body tip or the valve cap expediently consists of a rubber-elastic material.
  • valve body tip Due to the spring loading of the valve body, it is necessary to build up a pressure in order to overcome the weight of the valve body and the spring load. On the other hand, this ensures that the valve body lies firmly in the valve cap, that is to say is sealed, so that no liquid soap can escape from the valve cap or the nozzle bore.
  • the conical valve body tip also allows the cylindrical nozzle bore in the valve cap to be kept quite short and thus the space in which soap remains after the spring-loaded valve body is closed to be very small.
  • the spring-loaded valve body is provided with a piston according to a further embodiment of the invention.
  • This piston serves as a surface on which the pressurized soap acts during the pumping process in order to raise the valve body against the spring action.
  • the valve body moves in the direction of the compensating bore, which it thereby simultaneously closes, so that the soap is not conveyed back into the dispensing container, but is forced to exit through the outlet valve.
  • the wall mounting 1 consists of a flat plate which forms the rear wall 7 and receives bores 8 which are used to screw the wall mounting 1 to a room wall.
  • the holes 8 are made esenkt g, so that countersunk screws can be used.
  • the rear wall 7 is delimited on the right and left by side walls 59 which have a triangular shape and are angled in the lower region. Between the angled ends of the side walls 59 extends a channel-shaped holder 6, which is attached directly to the rear wall 7 and, like the guide 3, the spring 4 and the hook-shaped extension 5, serves to receive or fasten the dispensing container 2.
  • the guide 3 has the shape of a tab which is arranged offset inwards on the rear wall 7 by the wall thickness of the rear wall 7. In its upper region, it is separated from the rear wall 7 by free spaces 6o arranged on the right and left, so that the bridge 11, in which the guide groove 10 of the dispensing container 2 ends along its rear wall 9, engages around the guide 3.
  • the spring 4 carries at its upper end a hook-shaped extension 5 and is an integral part of the guide 3. It engages when the dispensing container 2 is inserted into the holding slot 12 located in the front part of the bridge 11, as a result of which the dispensing container 2 is locked in the wall fastening.
  • the dispensing container 2 has a U-shaped profile 14 on its base 13.
  • the web 16 of the U-shaped profile 14 extends parallel to the container rear wall 9 and is received by the channel-shaped holder 6 of the wall fastening 1.
  • the legs 15 of the U-shaped profile 14 arranged on the right and left of the web 16 have a triangular profile, i.e. they taper from the container rear wall 9 to the container front wall 61 and each have a bearing bore 17 in the downward-pointing tip of the triangle, while an elongated hole 18 extends parallel to the bottom 13.
  • a module 21 is arranged under the bottom 13 of the dispensing container 2, which partially penetrates the container bottom 13 and protrudes into the container interior 25.
  • the module 21 is designed as a ring extension and here forms the body of the pump 29, the tubular connecting piece, which is closed off by the pump membrane 56.
  • the pump membrane 56 has pot shape. Its central base piece is reinforced, the edge encompassing the cylindrical part of the pump 29 is connected to the module 21 by a retaining spring ring 55.
  • a pump channel 30 extends from the pump 29 in the direction of the outlet valve 31.
  • a relief channel 23 is connected to this pump channel 30 and opens into an opening 28 which is located in a mandrel 27 below the knife 26.
  • the opening 28 is covered by the neck 50 of the storage container 49, so that when the pump 29 is actuated, the liquid soap is not pressed back into the container interior 25, but rather reaches the outlet valve 31 via the pump channel 30.
  • the actuation of the pump diaphragm 56 takes place via an actuation lever 19.
  • the actuation lever 19 consists of a handle 37 and a cover plate 38, which closes the entire bottom area of the soap dispenser and thus prevents contamination of the pump 29 and the outlet valve 31 from the outside.
  • On the cover plate 38 is a Pressure pad 4o arranged, which consists of a cylindrical attachment with a flattened spherical neck. This pressure cushion 4o engages with the movement of the handle 37 on the pump membrane 56 and presses it into the module 21, as a result of which the soap located there flows out via the outlet valve 31.
  • a stop screw 41 arranged in the front area of the cover plate 38 serves to limit the movement of the handle 37 and thus to regulate the depth of penetration of the pressure cushion 40 into the pump membrane 56. This regulation adjusts the amount of soap to be dispensed.
  • the stop screw 41 is usually designed as a grub screw, which is arranged self-locking in the cover plate 38.
  • the handle 37 is mounted via articulated levers 39 which are resiliently connected to the handle 37. They carry at their ends outwardly directed stub axles 54 which engage in the bearing bores 17 of the U-shaped profile 14.
  • the soap dispenser When using the soap dispenser in disinfected rooms, it is necessary for the operator, for example a surgeon, to work with sterile hands and not to touch the handle 37 of the soap dispenser with his hands.
  • the soap dispenser should be actuated with the arm, for which purpose the actuating lever 19 is extended by spacers 42 so that the spacers 42 connect the handle 37 to the cover plate 38 and the articulated lever 39.
  • the cover 20 is provided in its lower region with two hinge arms 43, on which there are pivot pins 58. These pivot pins 58 engage in the elongated holes 18 of the U-shaped profile 14 so that the cover 20 can be moved in the direction of the wall mounting 1, so that the nose 46, which delimits the recess 45 in the cover 20, behind the catch 47 of the dispensing container 2 engages.
  • the recess 44 located in the bottom area of the cover 20 forms an opening for the outlet valve 31 through which the soap exits.
  • the viewing windows 48 are located in the hood side walls 63 of the cover 20 and are only delimited on one side by the hood side wall 63.
  • the opposite limitation takes place through the wall mounting 1, i.e. the side walls 59.
  • the storage container 49 has a cuboid shape and has on one long side an outwardly projecting neck 50, which is covered with a film cap 51.
  • the reservoir bottom 64 has two opposing depressions 52 which leave a web 53 in the middle. This web 53 is used for inserting the storage container 49 into the dispensing container 2, the depressions 52 allowing the web 53 to be gripped with the fingers.
  • the soap dispenser is opened by means of a lever 57, which consists of a flat material bent at one end in a crescent shape.
  • the crescent-shaped piece of the lever 57 is at the wall attached soap dispenser inserted into the recess 45 and the lever 57 then moved upward.
  • the lever 57 is supported on the wall of the room and lifts the nose 46 of the cover 2o out of the catch 47 of the dispensing container 2, so that the cover 2o is guided in the slot 18 through the pivot pin 58, moved towards the operator and to release the Output container 2 can be folded down.
