Definitions

  • the present invention relates to dispens- ers/measuring devices, particularly for dispensing a detergent, of the type comprising a hollow body having a mouth for dispensing the detergent into the washing liquid whilst the drum of a washing machine is rotating.
  • Dispensers of this type are used widely for dispensing detergent liquids or powders, particularly but not exclusively in washing machines which do not incorporate automatic measuring devices.
  • dispensers are also particularly useful for dispensing the very concentrated detergent compositions to which the detergents industry is turning increasingly, since they allow for a slow and controlled supply in the course of the washing cycle.
  • the detergent is a powder with a high concentration of active cleansing agent
  • the powder tends to form a paste which, as a result of the knocks to which the dispenser is subject in the course of the washing cycle, may come out of the mouth of the dispenser in a mass. This event is to be considered highly undesirable since the fabrics may be damaged by contact with the mass of concentrated detergent powder.
  • the primary object of the present invention is to provide a dispenser/measuring device which enables the detergent to be diluted within the hollow body and a diluted detergent solution to be dispensed continuously and progressively.
  • the subject of the invention is a measuring device/dispenser of the type mentioned above, characterized in that the hollow body has a plurality of elongate elements which extend within the body from its wall and can prevent or limit the dispensing of a mass of detergent.
  • a measuring device/dispenser comprises a hollow body 1 having a generally spherical configuration, with a dispensing mouth 2 at the top.
  • the body may be of other shapes, for example, a generally circular cylindrical shape.
  • the body of the dispenser is preferably made of soft and flexible plastics material, for example, PVC, polyurethane, polypropylene, propylene-ethylene copolymers (e.g. the HIFAX materials marketed by Himont) and various elastomers, but it may also be made of a rigid plastics material.
  • the material used preferably has a Shore A hardness of less than 100.
  • the measuring device/dispenser comprises a plurality of elongate rod-like elements 3a and 3b which extend obliquely inwardly from the side wall of the body.
  • the elongate elements comprise a first, upper set of angularly spaced rods 3a forming a first conical envelope and a second, lower set 3b forming a second conical envelope.
  • the elements 3a and 3b are also made of flexible material and are preferably integral with the wall of the body.
  • the elongate elements perform a retaining function when the detergent is constituted by a powder, preventing a concentrated paste from coming out in a mass. Moreover, the elements perform an important function as stirrers within the measuring device/dispenser.
  • the elongate elements are moved in various directions and thus perform a mixing action very similar to that of a rod stirrer. These movements destroy any lumps formed by the detergent powder in contact with the washing liquid.
  • the dispenser preferably has a rib 4 and an axial collar 5 adjacent its mouth.
  • the function of the rib 4 will be described in greater detail below with reference to the method of producing the device.
  • the elongate elements 3a and 3b may extend into the vicinity of the rib 4 or may extend a few millimeters beyond the rib; in order that the dispenser can be produced as an integral body by injection-moulding, the points at which the elongate elements 3a and 3b are attached to the wall of the body 1 are located in the hemispherical portion opposite the mouth 2 and hence below (with reference to the drawings) the horizontal plane which coincides with the maximum diameter of the generally spherical body 1.
  • the body of the measuring device/dispenser comprises a plurality of coplanar, baffle-like, elongate elements 6 which extend radially from the wall of the collar 5, above the rib 4.
  • the baffles 6 in this embodiment are also of flexible plastics material integral with the body and perform the main function of retaining the detergent powder mixture, preventing it from coming out in a mass. It is intended that the baffle-like elements 6 may also be used in the embodiment shown in Figures 1-3.
  • the elongate elements are constituted by a plurality of angularly spaced baffles 8a and 8b arranged in rings and extending from the base of the dispenser.
  • a first set of baffles 8a extending axially or obliquely, defines a first chamber with apertures 9 and a second set of baffles 8b defines a second, concentric chamber with apertures 10.
  • the retention of the detergent powder may be improved with the use of baffles of the type indicated 6 in Figure 4 adjacent the mouth of the dispenser.
  • the measuring device/dispenser is preferably produced by injection moulding by the steps shown schematically in Figures 6, 7 and 8. These drawings show two dies 11 and 12 and a male element 13 which has cavities 14 complementary in shape to the elongate elements to be produced.
  • the male element 13 has an annular groove 15 corresponding to the rib 4 of the measuring device/dispenser described above.
  • the plastics material is injected into the die 12 through a duct 17.
  • the two dies are then opened as shown in Figure 7 and compressed air is supplied through the duct 16 in the male element 13.
  • the rib 4 performs a sealing function between the body 1 and the male element 13 until, as the pressure increases, the body of the dispenser is practically thrown off the male element 13.
