Definitions

  • the present invention relates to a plastic crate. More in particular, the present invention relates to a plastic container for bottles and similar objects, the plastic container being provided with at least one coloured surface.
  • plastic crates are injection moulded from a base material to which colorants have been added, the resulting crate having a single, uniform colour, for example grey, black or blue.
  • a crate it is often desirable for a crate to have two, three or even more colours to improve its appearance, to boost the recognition of brand colours, and/or to enhance its visibility in poor light.
  • in-mould labels In plastic crates, such as bottle crates, additional colours are typically applied using labels, in particular so-called in-mould labels.
  • a well-known technique for applying labels is the in-mould labelling (IML) technique where a label (having any desired pattern) is placed in the mould before injection-moulding the crate.
  • IML in-mould labelling
  • the IML technique has several disadvantages.
  • the sizes of in-mould labels that can be applied are often limited. In particular, when a label is required that completely surrounds the crate, the "closed" circumference will have a visible seam.
  • a first type leaves a gap between two edges of the label, showing the crate through the gap.
  • a second type has an overlapping label edge, which is also visible. The overlapping edge will typically not bond well to the overlapped edge and come loose, which may lead to tearing of the label. In addition, dirt may collect under the overlapping edge.
  • a third tipe of seams is folded, thus avoiding loose edges.
  • the technique of folding seams is complicated and therefore relatively expensive.
  • Any seam will be all the more visible when the crate is stacked and the seams are not aligned. Providing two seams, one on either side of the crate and both carefully positioned so as to ensure alignment, is often less desirable. The problem of seams can be avoided by in-moulding a label having a closed circumference but this requires very small tolerances and is therefore relatively expensive.
  • the conventional IML technique has several disadvantages which make it less suitable for providing multiple colours in a plastic crate.
  • the IML technique is not suitable for applying a colour on any parts of the crate having a more complex shape, such as dividers or cones that may be present in a bottle crate.
  • a crate can be made from two (or more) differently coloured plastics which may be moulded either simultaneously or subsequently. Such a process, how ever, requires important modifications to the mould and is therefore relatively expensive. In addition, colour patterns defined by the mould cannot be easily changed.
  • the present invention provides a crate made of plastic, the crate having a base and at least two side walls upstanding from the base, wherein at least part of the surface of the crate is painted.
  • a crate having multiple colours can be obtained very economically. Any problems with seams are avoided, and the colours can be applied very quickly, in particular when spray-painting is used.
  • colour(s) can be applied after the moulding of the crate. This allows a standard crate to be moulded which is subsequently provided with any desired colour(s), possibly even a single colour. If two or more distinct colours are used, they may have any desired boundaries. In contrast to colour patterns and/or boundaries defined by the mould, painted area boundaries can easily and inexpensively be changed.
  • An additional advantage of the present invention is the fact that a paint layer applied on the crate protects the material of the crate from UV (Ultra Violet) radiation.
  • UV radiation which is contained in sunlight, for example
  • the plastic material of which the crate is made for example HDPE (High Density PolyEthylene) typically contains additives which prevent such degradation. If the crate is painted, these additives are no longer necessary, thus making the crate more economical.
  • a further advantage of the present invention is the fact that used and damaged crates can easily be reconditioned. Re-painting a used crate is much more cost-effective than recycling by grinding and re-moulding. In addition, by painting the colour of an existing crate can be changed, which may be advantageous when a crate changes ownership or when a brewery or other crate user changes its brand colour scheme.
  • the outer surfaces of the side walls are painted.
  • the present invention is not so limited and the interior of the crate may be painted as well.
  • the entire crate, including the lower surface of the base may be painted if desired.
  • the plastic has a first colour and the paint has at least a second colour. It is preferred that the first colour and the second colour are different, so as to provide a colour contrast using only a single paint colour.
  • the present invention is not so limited and the second (paint) colour may be substantially identical to the first (plastic) colour.
  • the paint (or at least part of the paint) may serve to shield the plastic material from UV radiation, or to cover an older paint layer.
  • the paint may have at least a third colour different from the second colour. That is, the paint may have at least two distinct colours, thus providing multiple colours, even if the plastic material of the crate is entirely covered by the paint.
  • the present invention also provides a method of providing a crate having at least two colours, the method comprising the steps of:
  • the paint may be metallic paint, containing metal particles, and/or have a metal (gold, silver, bronze) colour to give the appearance of a metal crate.
  • a metal gold, silver, bronze
  • any other colours may also be used.
  • the step of painting involves spray-painting.
  • spray-painting relatively large surfaces can be painted in a short time.
  • a brush, roller or other application tool could be used.
  • the step of providing a crate made of plastic involves injection moulding.
  • the crate of the present invention is preferably integrally made, that is, the crate consists of a single body of plastic.
  • the crate of the present invention may also be assembled from a set of parts, for example separately made side walls mounted on a base member.
  • the plastic crate 1 shown merely by way of non-limiting example in Fig. 1 comprises a base 2 and side walls 3. Two side walls 3 are provided with handle openings 5. The side walls 3 define an interior 4.
  • the crate of Fig. 1 is integrally moulded, although the invention is not so limited.
  • the crate is at least partially painted.
  • the crate 1 is shown to have a painted band 8 which extends over all four side walls 3.
  • a painted area (or band) 9 is present below the painted area (band) 8.
  • the top part of the side walls 3 is, in the example shown, not painted. If the plastic material of the crate, the upper painted area 8 and the lower painted area 9 all have different colours, a three-colour crate can be provided with only two colours of paint.
  • the area 9 may have the same colour as the upper painted area 8.
  • the upper parts of the side walls 3 may also be painted, or the area 9 could be an unpainted area.
  • the interior 4 of the crate could for example be left unpainted (bare plastic), while the exterior (outer surfaces of the side walls 3) could be painted.
  • the side walls 3 can be either entirely or partially painted. Various alternatives will become apparent to those skilled in the art.
  • suitable shielding tools can be used to shield part of the crate while applying paint of a particular colour, which shielding tools are then removed.
  • the plastic material of a crate that is painted over substantially its entire (outer) surface no longer requires protective additives. Accordingly, the material costs of the crate can be reduced. A better protection against UV radiation is obtained if the interior of the crate is also painted, including any dividers, cones, columns and other elements.
  • the crate of Fig. 1 has substantially even planar side walls.
  • the side walls 3 may be provided with ridges extending from the top and or the bottom of the side walls in the plane of the base 2. That is, such ridges may extend sideways so as to protect the side wall surfaces from damage.
  • the crate of the present invention is made of a suitable plastic material, such as PE (PolyEthylene) or HDPE (High Density PolyEthylene).
  • the paint can be any suitable paint as may be determined experimentally.
  • the paint may be based on solvents or be water-based. Any paint colour may be used, including but not limited to red, blue, grey, yellow, metal (e.g. copper, silver or gold) or metallic, brown, black, white, purple and pink.
  • the present invention also provides a method of providing a crate having at least two colours, the method comprising the steps of:
  • the present invention is based upon the insight that painting a crate is a very economical way of obtaining a crate having multiple colours, much more economical than using inserts, in-mould labels and plastic material having multiple colours.
