Definitions

  • This invention relates to a stirrer which is used for the stirring of liquids, in particular paint, but is not restricted thereto.
  • Stirrers have been paddles of rod or other shapes having formations of various configurations at their ends inserted into the containers holding liquids, the other ends being held either manually or in the chucks of drills provided to rotate them.
  • a stirrer suitable for use in the stirring of a viscous liquid to effect homogeneity of the constituents comprising an elongate member having an operative part of cross section providing flexibility in the plane of one axis and substantial rigidity in the plane of an axis transverse thereto and extending at one extremity into a formation adapted to be engaged by means for rotating the formation about its axis.
  • the member is of mouldable plastics material and the mouldable material is thermoplastic.
  • the operative part of the member is a strip of moulded plastic the width of which is large compared to the thickness and preferably having a substantially flat surface.
  • the operative part may have a portion of increased cross sectional area near the end thereof remote from the formation.
  • the operative part may be moulded into an arcuate configuration and this portion may be an enlarged moulded tip.
  • a paint stirrer for stirring of paint in a container.
  • the stirrer comprises an elongate member 1 which is integrally moulded from thermoplastic material in two parts, an operative part 2 which, in use, is inserted to the full depth of the container of paint and a connecting part 3.
  • the operative part 2 is an elongated rectangular flat paddle, of width 4 and thickness 5 and the connecting part 3 is a formation moulded to cooperate with the chuck of a power drill to rotate the stirrer in use.
  • Figure 2 illustrates a second embodiment of the paint stirrer which is similar to the first embodiment excepting that the operative part 6 is moulded in an arcuate configuration 7 and
  • Figure 3 illustrates a third embodiment of a paint stirrer similar to the second embodiment excepting that the operative part 6 has a tip formation 8a integrally moulded at its lower end in use.
  • the chuck 9 of a portable power drill 10 is connected to the connecting part 3 of the stirrer and the operative part 11, which is of sufficient length therefor, is inserted into a paint container 12 to the full depth thereof. Power is switched on and the stirrer is rotated within the paint 14. Being flexible in one plane, the tip 13 of the stirrer tends to move away from the transverse axis about which it is rotated and with increase in the speed of rotation, the angle which the tip subtends with the axis of rotation, increases due to the increase in centrifugal force induced at the tip and the flexibility of the stirrer.
