Definitions

  • the present invention relates to a paint container comprising a receptacle and a lid, wherein the lid comprises a metal lid portion and a plastic lid portion.
  • the metal lid portion is a central portion allowing the paint container to be used in a punching type colorant dispenser punching the metal lid portion prior to dispensing colorant into the paint.
  • the plastic lid portion is a peripheral portion encircling the metal lid portion.
  • a colorant dispenser apparatus adapted for metal paint containers may punch a hole in the container, in the container lid, and provide the colorant into the container via the hole. Thereafter the hole is plugged and the container is shaken to obtain an even colour distribution of the paint.
  • Such a punching type colorant dispenser apparatus is disclosed in EP 0 779 241 .
  • a punching type colorant dispenser apparatus punches the container it is important that the container is rigid and designed to withstand the forces from the punch. The punch should cause a hole in the centre area of the lid but the remaining parts of the container must not be damaged.
  • WO 2007/055651 discloses a metal paint container which may be used in such colorant dispenser apparatus.
  • a problem with metal paint containers such as the metal paint container shown in WO 2007/055651 , is that they are rather expensive to produce. Therefore, it is becoming more and more common for paint producers to abandon metal paint containers and instead use plastic paint containers.
  • a plastic paint container may however not be used in a punching type colorant dispenser apparatus since a plastic container is not rigid enough to withstand the forces from the punching of the container. Instead, when colorant should be provided into basic coloured paint in a plastic paint container, the lid must be removed prior to inserting the paint container in a colorant dispenser apparatus.
  • a disadvantage of using plastic paint containers is, thus, that removing the lid requires manual work.
  • a metal paint container One way of minimizing the costs, and in addition the weight, of a metal paint container is to make the container as thin as possible, but still thick enough to be able to withstand the forces from the punching type colorant dispenser apparatus.
  • the container may be made from a metal plate having an even thickness which is normally between 0.1 mm and 0.5 mm. Further, in order to reduce the amount of material required it is important to have good shape permanence, particularly at the edges of the container.
  • the present invention relates to a paint container comprising a receptacle and a lid, wherein the lid comprises a metal lid portion and a plastic lid portion.
  • the metal lid portion is a central portion allowing the paint container to be used in a punching type colorant dispenser punching the metal lid portion prior to dispensing colorant into the paint.
  • the plastic lid portion is a peripheral portion encircling the metal lid portion.
  • the plastic lid portion comprises a lid sealing portion sealing the lid to a circumferential plastic receptacle sealing portion of the receptacle.
  • An advantage with the paint container is that the metal lid portion allows the container to be used in a punching type colorant dispenser.
  • the entire lid is not made of metal but only a portion of the lid, which may be punched, is made of metal. Since the portion of the lid which seals to the receptacle is made of plastic it becomes possible to have a larger portion of the lid made of plastic than in prior art paint containers, which saves cost.
  • Punching type of colorant dispensers are known in the art, for instance disclosed in SE 356 933. Punching type of colorant dispensers are arranged to punch an opening is the lid of the paint container, i.e. to penetrate the lid.
  • Colour pigment may be added by the device that is used for punching the opening, or a separate device may be inserted in the opening to provide colorant, i.e. colour pigment, into neutral coloured paint in the paint container. Paint containers that are suitable for being used in punching type of colorant dispensers may be enforced to withstand the forces from the punching colorant dispenser.
  • the plastic receptacle sealing portion is made of plastic which allows the sealing of the paint container to take place directly between the receptacle and the lid without having to have an intermediate packing to assure a tight fit.
  • the plastic portion of the lid may seal against a plastic portion of a receptacle.
  • the plastic lid portion comprises a holding portion to hold the lid onto the receptacle. If the lid is held on the receptacle by means of, for instance, a circumferential flange of the receptacle the plastic lid portion may be shaped with a holding portion in the form of an edge to cooperate with the flange of the receptacle. Since plastic is flexible it may be easy to seal, open and re-seal such a paint container.
  • the plastic lid portion is made in one piece with the lid sealing portion.
  • the lid sealing portion is integrated in the plastic lid portion.
  • the plastic lid portion comprises one piece of plastic which includes the periphery of the lid as well as the lid sealing portion.
  • the lid sealing portion may seal directly onto the receptacle sealing portion or have a separate packing or other sealing body which is attached to the to the lid sealing portion to improve the sealing.
  • the receptacle is a plastic receptacle.
  • Plastic paint receptacles are cheaper to manufacture than metal paint receptacles.
  • the lid comprises a joint portion along which a peripheral portion of the metal lid portion is joined to a fixing portion of the plastic lid portion.
  • the peripheral portion of the metal lid portion may be embedded in the fixing portion of the plastic lid portion along said joint portion.
  • the joint portion comprises a portion of the plastic lid portion, i.e.
  • the fixing portion, and a portion of the metal lid portion i.e. the peripheral portion of the metal lid portion.
  • the peripheral portion of the metal lid portion has the same circumferential shape as the lid and the receptacle, for instance circular.
  • the peripheral portion of the metal lid portion has a different circumferential shape than the lid and the receptacle.
  • the peripheral portion of the metal lid portion may have some protrusions which are embedded deeper into the fixing portion of the plastic lid portion to strengthen the joint between the metal and plastic portions of the lid at certain points.
  • the lid sealing portion encircles the joint portion.
  • the joint portion is located closer to the centre of the lid than the lid sealing portion. Since the periphery of the metal lid portion is included in the joint portion this embodiment has the entire metal lid portion encircled by the lid sealing portion.
  • the joint portion comprises between 1 mm and 50 mm of the periphery of the metal lid portion, more preferably between 2 mm and 30 mm of the periphery of the metal lid portion, most preferably between 4 mm and 15 mm of the periphery of the metal lid portion.
  • the joint portion comprises between 1 mm and 50 mm of the periphery of the metal lid portion.
  • the periphery of the metal lid portion which is included in the joint portion, should have a certain size, however, in order to minimize the content of metal in the lid, and thus lowering the costs of the lid, the joint portion should not be too large.
  • the length of the metal periphery which is included in the joint portion should be measured along the surface of the metal lid portion, i.e. following the shape of the periphery of the metal lid portion and not following the overall shape of the joint portion.
  • the peripheral portion of the metal lid portion comprises a bent portion having at least one a bend.
  • a bent metal portion may be joined in a more durable manner with a fixing portion of the plastic lid portion.
  • a bent metal portion may be less likely to slide out of the fixing portion since the bent metal portion is firmly held within the fixing portion and may transfer forces to the fixing portion rather than sliding out of the fixing portion.
  • the bent portion comprises at least two bends.
  • a bent metal portion which is bent twice may stay even better within the fixing portion of the plastic lid portion. This may in particular be the case if the two bends are made in opposite directions. For instance, if a first bend of the peripheral portion of the metal lid portion is made upwards, with respect to the horizontal main direction of the lid, and a second bend is made downwards.
  • the present invention further relates to a colour refraction method comprising arranging a paint container in a punching type colorant dispenser, wherein the paint container is sealed by a circumferential receptacle sealing portion of a receptacle in cooperation with a circumferential lid sealing portion of a plastic lid portion of a lid; punching an opening in a metal lid portion of the lid, the metal lid portion being a central portion of the lid and being encircled by the plastic lid portion; and dispensing colorant into the paint.
  • the receptacle may be a plastic receptacle.
  • colour refraction method is meant a method for adding colour pigment to base colour and thereby retrieving a coloured paint.
  • a colour refraction method may comprise arranging a paint container comprising paint, usually white paint, in a colorant dispenser. Further, a colour refraction method may comprise the steps necessary for dispensing colorant, i.e. colour pigment, into the paint to arrive at a paint of a desired colour tone.
