Definitions

  • This invention relates to a container for roller-applied coating compositions and its use in coating procedures for rough surfaces.
  • the first type is widely used in the United Kingdom and it employs a tray provided with a well and a flat surface which slopes down to the well.
  • Coating composition is poured from a container into the well and then a roller is loaded by inserting it into the coating composition in the well where it picks up an excessive amount of the composition.
  • the excess is removed by withdrawing the roller from the well and rolling it over the flat surface whereupon excess composition is transferred onto the surface from where it drains back down the slope into the well.
  • the use of such trays presents several risks of mess. Firstly, coating composition has to be poured from a container into the well which can be a messy operation when performed by amateurs, especially if the container is large and heavy. Secondly, the tray is awkward to hold or carry which creates a risk of tilting and consequent spillage of the composition from the well or flat surface. Thirdly, the tray has to be cleaned after use which can also be a messy operation when performed by amateurs.
  • the second technique for removing excess coating composition from a roller is widely used in Germany and it employs a grid (or "Gitter” to use the German word).
  • the grid is held over an open container which is dimensioned so as to allow a roller to be inserted into the container and which contains a volume of coating composition.
  • the roller is inserted into the coating composition where it picks up an excessive amount of the composition.
  • the roller is withdrawn from the coating composition and excess composition is removed by rolling the roller across the grid so as to transfer coating composition from the roller onto the grid from which it drips back into the main volume of the coating composition.
  • the technique requires the grid to be held steadily over the container both whilst the roller is being rolled across it and whilst excess composition is dripping back into the main volume of composition. Such steady control of the grid can be difficult for amateurs particularly if a large roller is being used.
  • the grid either has to be discarded or cleaned and both options can result in coating composition contaminating other places.
  • a further technique involves a controlled loading of a roller by means of a grid floating on a semi-solid coating composition contained in a tray.
  • the roller is loaded by rolling it back and forth across the floating grid so that coating composition flows through the grid and onto the roller which loads in a more controlled way with less risk of excessive loading.
  • the technique requires the composition to be supplied in a tray dimensioned so as to be able to receive the back and forth movement of the roller but it works well provided that excessive pressure of the roller on the grid is avoided. However, avoidance of excessive pressure does require skill especially if the tray is being used in a restricted space such as at the top of a ladder.
  • the coating composition must also be semi-solid which is not ideal for use on rough surfaces.
  • One of the objects of this invention is to provide a container for roller-applied coating compositions which container assists relatively mess-free removal of excess composition from a roller and which is especially suited for use with compositions of a viscosity high enough to facilitate uniform coating of rough or overlapping surfaces.
  • this invention provides a container for a roller-applied coating composition which container has an opening dimensioned so as to allow a roller to be insertable into the container and into coating composition if contained in the container wherein the container is also provided with a grid for removing excess coating composition from a roller which grid is located below the opening and extends only part way across the container.
  • any coating composition contained in the container should preferably have a Rotothinner mid-shear viscosity at 20°C of at least 5 Pa.sec (Pascal.second) and an ICI Cone & Plate high shear viscosity of at least 0.03 Pa.sec. Usually the mid-shear viscosity will not exceed 130 Pa.sec and the high shear viscosity will not exceed 0.1 Pa.sec.
  • the dimensions of the opening into the container are chosen so as to allow a conventional paint roller to be insertable down into the container.
  • the provision of a grid which extends only part way across the container makes it possible to leave an access for the roller past the grid into the lower portion of the container and particularly into any coating composition supplied in this lower portion.
  • the roller picks up an excess of the composition.
  • the roller may then be withdrawn to just above the grid and subsequently rolled across the grid to transfer excess composition from the roller onto the grid from where it drips back into the main volume of the coating composition.
  • the grid is located sufficiently below the opening, the whole process of removal of excess coating composition from the roller to the grid and its return to the main volume of the composition can be performed within the protection of the container making mess almost impossible to create.
  • the optimum spacing of the grid from the opening will depend to a large extent on the diameters of the rollers intended for use with the container.
  • the distance from the top surface of the grid to the opening should be at least 75% of the diameter of the largest roller anticipated to be used. A distance of 100% of this diameter will ensure full protection against mess from the container and in practice a minimum distance of about 400mm is usually chosen.
  • the distance from the grid to the base of the container is chosen to be commensurate with the volume of coating composition required to be supplied.
  • the grid may be supported in the container by any convenient method such as adhesive bonding to the walls of the container.
  • it is preferably provided as part of a collar which is inserted as a close fit into the container and snap-fitted around the rim which defines the opening into the container.
  • the collar may also carry snap-fit means for receiving a lid which closes the opening into the container.
  • Such an arrangement has the advantage that the lid and collar can be co-assembled and then the co-assembly can be snap-fitted onto the container in a single operation after the container has been filled with coating composition.
  • the lid is more flexible than the collar so as to facilitate removal of the lid from the collar without causing an unintentional displacement of the collar from the container. Further resistance to such unintentional displacement may be achieved by providing a frangible bond or an easily disengageable connection between the collar and the container which requires a positive act to break or disengage.
  • An adhesive bond may be used.
  • the container, grid or collar and lid may be made by injection moulding thermoplastics such as polyolefins including polypropylene, high, low and medium density polyethylenes and copolymers of propylene and ethylene.
  • thermoplastics include polyamides, polyesters and butadiene-styrene copolymers.
  • Figure 1 shows a plan view of an empty container 1 having a base 2 and into which a close fitting collar 3 has been inserted.
  • Base 2 and Collar 3 are more clearly shown in Figure 2.
  • Figure 2 also shows top rim 9 of container 1 which defines an opening into container 1 which is rectangular and dimensioned so as to allow insertion of a conventional paint roller into container 1.
  • Collar 3 carries a horizontal grid 6 which extends half way across container 1 so as to leave an access 7 which is amply large enough to allow passage of a conventional paint roller.
  • the lower portion 1a of container 1 is filled with coating composition 5 to a level below grid 6 and is then closed by lid 4.
  • lid 4 is removed thereby opening container 1 and the roller is inserted via access 7 into coating composition 5.
  • Withdrawal of the roller produces a roller which is loaded with an excess of coating composition 5.
  • the roller is withdrawn through access 7 and then rolled across the upper surface of grid 6 whereupon excess coating composition 5 is transferred from the roller onto grid 6.
  • the roller now loaded with an appropriate amount of coating composition 5 can be completely withdrawn from container 1 whilst the removed excess coating composition 5 drips down from grid 6 back into the main volume of coating composition 5 in the lower portion 1a of container 1.
  • the entire procedure for loading a roller with an appropriate amount of very viscous coating composition 5 and for the return of excess composition to the lower portion 1a of container 1 is performed within the protective confines of open container 1 and so the risk of mess is virtually nil.
  • Figure 3 shows on a larger scale the top right corner of container 1 when lidded. In particular, it shows how lid 4 makes a snap-fit onto a resilient top rim 8 of collar 3 and how in turn collar 3 snap fits onto top rim 9 of container 1.
  • Lid 4 is provided with a dependant resilient skirt 11 which in turn is provided with an inwardly projecting rib 12 engaged by a co-operating outwardly projecting rib 13 provided on resilient rim 8 of collar 3. Press-fitting rib 12 on lid 4 over rib 13 on collar 3 causes lid 4 to become engaged on collar 3 with a snap fit.
  • collar 3 is provided with a dependent resilient skirt 14 which in turn is provided with an inwardly projecting rib 15 engaged by a co-operating outwardly projecting rib 16 provided on resilient rim 9 of container 1. Press fitting rib 15 on collar 3 over rib 16 on rim 9 cause collar 4 to become engaged on container with a snap fit.
  • Rib 9 is also provided with a dependent reinforcing skirt 17 which resists distortion of rim 9 so helping to maintain a good snap fit during transportation of the container. Skirt 17 is also provided with a sloping shoulder 18 to which skirt 14 of collar 3 can be lightly adhesively bonded to guard against unintentional removal of collar 3 from container 1.
  • containers according to this invention can be used in procedures for coating both rough and smooth surfaces, they are especially well suited for use in procedures for coating rough and uneven surfaces such as those found on sawn wood fence panels and particularly where panels overlap. Hitherto the awkward recesses in such surfaces could only be efficiently coated by amateurs if the amateurs used brushes and applied relatively fluid coating compositions.
  • Such fluid coating compositions would have Rotothinner mid-shear viscosities as low as about 0.08Pa.s at 20°C and ICI Cone & Plate high shear viscosities as low as 0.025Pa.s at 25°C. Compositions of this high degree of fluidity are not suitable for efficient application by roller.
  • Suitable highly viscous coating compositions need to have Rotothinner mid-shear viscosities of from 5 to 130 (preferably from 60 to 130) Pa.sec at 20°C and ICI Cone and Plate high shear viscosities of from 0.03 to 0.1 (preferably from 0.07 to 0.1) Pa.sec at 25°C.
  • this invention also provides a method for applying a coating composition to a rough surface using a roller wherein
  • the method is particularly useful in applying a coating composition which contains a biocide of the type used in the preservation of wood.
  • This invention also provides a lidded container provided with a grid wherein the container contains a highly viscous coating composition as described above.
  • ICI Cone & Plate high shear viscosity is determined at 25°C as follows:
  • Rotothinner mid-shear viscosity is determined at 20°C using the Sheen/ICI Rotothinner (Electrical Model) described in the Sheen leaflet headed "Viscosity Sheen” published by Sheen Instruments Limited of Scientific on Thames, Surrey, England.
