Definitions

  • the invention relates to a dosing device for dispensing a flowable material.
  • Such a material may, for example, have a tacky consistency, i.e. stick to a surface by itself.
  • flowable materials for example gels
  • the toilet can be cleaned or disinfected in this way.
  • EP 2 361 850 B1 describes a metering device for dispensing a flowable material onto the inside of a toilet bowl. To do this, a piston is inserted into a cylindrical body. Upon insertion, the plunger displaces a flowable material contained within the cylindrical body to be dispensed through a dispensing port.
  • the object of the invention is to provide a dosing device for dispensing a flowable material which enables improved application to the inside of a toilet bowl.
  • the dosing device has at least two cylindrical bodies, the interior of each of which forms a cavity for receiving the flowable material.
  • This flowable material can be, for example, a gel in the colloquial sense or another flowable material with high or low viscosity. It is essential that the flowable material is designed in such a way that it does not automatically emerge from the dosing device and also has a sticky consistency, so that it automatically adheres to the inside of a toilet bowl when it is applied. Furthermore, the material can have such a viscosity that it retains its shape after application, provided it is not deformed by external influences.
  • each cylindrical body has a first open end and a discharge opening opposite thereto.
  • the cylindrical bodies can, for example, be circular-cylindrical, but can also have other cylindrical shapes.
  • the dosing device also has two pistons for axial insertion into the respective first open end of the first and second cylindrical body.
  • the introduction is such that the flowable material is displaced by the plunger and pushed out of the dispensing opening.
  • the dosing device has at least one first connecting element, by which the at least two cylindrical bodies are connected at a distance from one another in such a way that they can be moved relative to one another.
  • the axial cylinder axes of the cylindrical bodies are arranged parallel to one another. This relates to a condition where the metering device is not bent. This is therefore the idle state of the dosing device.
  • the cylindrical bodies move relative to one another, so that they can be tilted relative to one another.
  • a tilting of the cylinder axes relative to one another can take place in both possible planes. If the tilting takes place in the plane perpendicular to the longitudinal direction of the dosing device, twisting or torsion of the dosing device takes place.
  • each of the at least two cylindrical bodies has a spacer extending in the axial direction away from the cylindrical bodies across the at least two dispensing openings extends out so that a cavity is formed in the axial direction between the distal end of the at least one spacer at the at least two dispensing ports.
  • spacers are used to be able to place the front end of the dosing device on the inside of a toilet bowl, so that a distance can be maintained in the axial direction from the inside of the toilet bowl to the dispensing opening.
  • the free-flowing material can be dispensed into the cavity created here. It is thus ensured that when the flowable material is being applied, no pressure is exerted on the flowable material by the dosing device, so that it can be dispensed in a visually appealing form.
  • the spacers can also ensure that the dosing device and in particular the dispensing openings are always positioned at a defined distance from the inside of the toilet bowl while the flowable material is being dispensed.
  • each of the at least two cylindrical bodies has at least one projection running in the radial direction on its inner wall at a height spaced apart from the first open end. This serves to better hold the piston in the respective cylinder, so that in particular it does not fall out of the cylinder.
  • the at least one spacer is L-shaped, with the short end of the L of the at least one spacer extending radially outwards from the outer lateral surface of the cylindrical body, with the long end of the at least one spacer extending in extends in the axial direction beyond the height of the discharge opening of the cylindrical body.
  • the at least two pistons are flexibly connected to one another by at least one second connecting element.
  • the pistons and the second connecting element corresponding to the cylinders and the first connecting element can be bent with each other when applying the gel to the inside of the toilet bowl.
  • the at least one second connecting element has at least one gripping element. This can in particular be arranged centrally between the at least two pistons.
  • the second connecting element can have at least one opening above the at least one piston. These are used for easy production of the second connecting element.
  • the second connecting element is preferably made of plastic, with the openings mentioned simplifying the design of the tools that are used for the production of this plastic part. The product can thus be manufactured more cost-effectively.
  • the dosing device has at least four cylindrical bodies and at least four pistons. Furthermore, in this embodiment it has at least three connecting elements which are each arranged between two adjacent cylinders. This makes it possible to dispense four free-flowing materials separately, which can also be different materials, for example.
  • the first connecting element is preferably flexibly arranged between the first cylindrical body and the second cylindrical body.
  • the second connecting element is correspondingly preferably flexibly arranged between the second and the third cylindrical body, while the third connecting element is preferably flexibly arranged between the third and fourth cylindrical body.
  • the at least four cylindrical bodies and the at least four pistons are arranged in a row on a straight line.
  • other geometric configurations are also possible.
  • FIG 1 shows a side view of an embodiment of the metering device 10 according to the invention. This is used to dispense a flowable material 12a - 12d, which is received in four cylindrical bodies 14a - 14d. Each of the cylindrical bodies 14a - 14d has a first open end 16a - 16d as well as a discharge opening 18a - 18d opposite this in the axial direction (see also figures 2 , 5 and 6 ).
  • the dosing device 10 also has four pistons 20a-20d for axial insertion into the first open end 16a-16d of a cylindrical body 14a-14d, respectively. This takes place in such a way that the flowable material 12a - 12d is displaced by the four pistons 20a - 20d and pressed out of the dispensing openings 18a - 18d.
  • the pistons are connected via the connecting element 21 (see Fig. figure 5 ) flexibly connected to each other.
  • This also has two grip elements 22, 23, through which it can be gripped by a user when applying the gel.
  • the axial axes of the cylindrical bodies 14a-14d are denoted by Z1-Z4. These run at rest, i.e. in a non-bent state Condition of the dosing device (e.g. according to figure 1 ) parallel to each other.
  • the dosing device When the gel is applied by the dosing device according to the invention on the inside of a toilet bowl, the dosing device is bent in such a way that the axes Z1-Z4 no longer run parallel to one another.
  • the toilet bowl would be on the right side and have a concave shape. This means that when the dosing device 10 is placed on the inside of the toilet bowl, the spacers 19a, 19b of the outer cylindrical bodies 14a and 14d first come into contact with the toilet bowl.
  • the dosing device 10 then bends in such a way that the two inner cylindrical bodies 14b and 14c are pushed forward in the direction of the toilet bowl, while the outer cylindrical bodies 14a, 14d are held back.
  • This is preferably made possible by elastic properties of the connecting elements 15a - 15c. It is thus possible for the distal end of each cylindrical body 14a-14d to come into contact with the inside of the toilet bowl even if it has a curved shape.
  • the dosing device 10 returns to its original state (namely the state of rest according to figure 1 ) returns, but with the four pistons 20a, 20d fully inserted into the cylindrical bodies 14a-14d.
