  CASE A CLAIRE-VOIE ON WHICH IS BONDED

A FILM PRINTED LABEL

  The present invention relates to a crate to which is affixed a printed label which can be laminated under the action of a pressurized fluid, in particular a crate for bottles, said printed label comprising a sheet which is provided with 'a print and a layer

glue.

  Labels which can be coated with a fluid, in particular water, under a relatively high pressure, for example greater than 35 bar, are described in Belgian patent application number 9701025 in the name of the applicant who hasn't yet

been published.

  Labels of this type have the advantage that they are laminated for each crate wash cycle and are therefore suitable for providing information as such.

temporary.

  2. When a label of this type is applied directly to a crate that has not been printed, lamination of the label with pressurized fluid is no problem. However, promotional actions require the temporary application of a label on a

existing print.

  When printing with ink, it is necessary, in order to obtain good adhesion, to flame-treat the printing area, so that the surface tension of this is increased.

area.

  This treatment nevertheless has the consequence that the aforementioned pressure-laminatable labels, which are particularly suitable for providing information on a temporary basis, can no longer be easily laminated when they are applied to

such an impression.

  Therefore, a crate with printing cannot have any labels

  film-like of this type over its impression.

  The subject of the invention is a crate which

  eliminates the aforementioned drawback.

  This object is achieved in accordance with the invention by the fact that the film-coated label is applied with the aid of a fluid to a label of the "in mold" type, that is to say a label which, when of the manufacture of the crate in a matrix, is applied in the latter before injecting the

synthetic material.

  Therefore, the "persistent" print is not applied directly to an area of the crate that has been flame treated, but on an "in mold" label for which a heat treatment

flame is of course useless.

  The use of an inmould of this type is known, but not as the basis on which it is applied

  a temporary label, therefore laminated.

  In order to better indicate the characteristics of the invention, there is described below, by way of example, without any limiting character, a preferred embodiment of a crate according to the invention with reference in the accompanying drawings in which: Figure 1 shows a perspective view of a crate according to the invention; Figure 2 shows, schematically and on a larger scale, a cross section taken along the line II-II in Figure 1; Figure 3 shows, on a larger scale, the part of the cross section of Figure 2

indicated by arrow F3.

  The plastic crate shown in FIG. 1 comprises, in a side wall 1, a permanent "inmould" label 2 and a label 3 which can be coated with a pressurized fluid, which covers the label 2 in whole or in

part.

  The permanent "in mold" label 2 is constituted by a support 4 of synthetic material, preferably of the same synthetic material as that from which the crate was molded by injection, for example high density polyethylene. , a microporous layer 5 or what is called a "clay-coating" applied to the support, a print 6 and an external transparent protective layer 7,

  for example made up of an acrylate-based varnish.

  In this transparent protective layer 7, it is possible to insert a stabilizer against the effects of ultraviolet radiation and, where appropriate, the grains of a slip agent, in particular consisting of a polymer such as for example low density polyethylene. This label 2 offers high resistance against tearing and scratching, and can withstand a large number of high pressure washing cycles.

in a wash lane.

  The laminable and also printed label 3 comprises a transparent sheet 8 which is made of a synthetic material such as polypropylene,

  polyethylene, polyester or polyvinyl.

  On the dorsal side of this sheet 8, a

printing 9 with ink.

  This impression 9 consists of several layers

  10 different colors of ink.

  On the side of the label 2, a layer of covering ink 11 is applied to these ink layers, which completely covers the layers.

ink 10.

  On the print 9, a layer of glue 12 is applied, so that the glued and printed sheet 8 can be glued under pressure and with which in any case the label 3 is glued to the protective layer 7

from label 2.

  The bonding force can be adjusted so that the label 3 becomes detached from the permanent label 2 already after a washing cycle in a usual washing installation for a bottle, if necessary in

adding an alkali.

  In any case, the adhesive layer 12 is able to come off at once with pressurized fluid, in particular with pressurized water without leaving any trace of adhesive, but also without damaging the permanent label. 2. The required pressure can be between 35 and 50 bar and

  it is preferably around 45 bar.

  A suitable glue for this purpose is a glue capable of being dispersed in water or a solvent glue or else a UV-curable glue which is subjected to drying or to polymerization after its

application.

  By applying the laminable label 3 to the permanent label 2 and not to the bare synthetic material of the crate, it can not only be applied without problem with good adhesion, but also laminated later easily with pressurized water without leaving residues on the label 2 and without damaging the latter, so that the latter can again play its role after filming. The invention is in no way limited to the forms

  of embodiments described above; a crate

  route of this type can be carried out in different

  variants without departing from the scope of the invention.
