Definitions

  • the present invention relates to the technical sector concerning making articles and objects (such as, for example, articles for the home, articles for containing foodstuffs or, more in general, containers of various types), by injection moulding of thermoplastic material.
  • the invention relates to a process for realising an article with an informative/decorative/illustrative label associated thereto, using the injection moulding method, and to an article with a label obtainable using the process.
  • Injection moulding is an industrial production method for realising articles using thermoplastic material, which are injected in the fluid state and under high pressure internally of moulds in which, subsequently, they are solidified following cooling and give shape to the final article.
  • Injection moulding is a process carried out using a mould constituted, for example, by a matrix and a punch the shapes of which will give shape to the final article: the matrix and the relative punch are conformed so that the punch can be inserted and sealedly coupled to the matrix so that when they are coupled an empty space is present between the punch and the matrix into which the thermoplastic material can be injected in the fluid state and at a high pressure.
  • the thermoplastic material will occupy all the empty space, taking on the shape and obtaining the article having the desired shape, once the thermoplastic material has been cooled.
  • a known process for realising an article with the label includes, firstly, realising the article by injection moulding, as described above, and then proceeding to the application of the label, for example using gluing or a self-adhesive label.
  • the label will be positioned and applied on the external surface of a wall or a face of the article and, consequently, it will be destined to suffer wear and damage over time: a paper label might easily tear, while a plastic label might get scratched or discoloured. Therefore, the information reported in the label would become illegible and any images or graphics contained thereon would inevitably get damaged and lose their aesthetic effectiveness.
  • a further known process, at present carried out for realising articles with a label by injection moulding, includes carrying out an application of the label during the injection moulding step of the article.
  • This process includes the use of labels known as IML (In Mould Label).
  • IML labels are particular labels which are realised so as to be constituted by a film, on which graphic decorative images have been printed/painted, which images are to be transferred to the final article, which comprises at least a support layer realised in a thermoplastic material. These IML labels are inserted in the matrix of the mould, used in injection moulding for obtaining a determined article, before injecting the thermoplastic material in the mould.
  • the support layer of the IML labels must be made of a thermoplastic material so as to be chemically compatible with the thermoplastic material injected into the mould for realising the article: in this way, following the cooling and solidification of the thermoplastic fluid material injected into the mould, the label will chemically adhere to the thermoplastic material.
  • This known process includes: applying an IML label to the walls of the mould matrix, so that the support layer of the label faces the empty space which will be created when the punch is inserted in and sealedly coupled to the matrix for forming the mould; sealedly coupling the punch and the matrix; injecting the thermoplastic material in the fluid state and at high pressure in the empty space of the mould so that, by effect of the high temperature and pressure of the fluid thermoplastic material, the support layer of the label at least partly hardens and the label is incorporated in the thermoplastic material injected into the mould for realising the article; cooling the injected thermoplastic material so that once solidified the article with the label is formed, where the label has become an integral part of the article.
  • the label while being an integral part of the article, has the surface thereof on which graphic decorative images are printed/painted, on the external surface of a wall or face of the article, facing towards the surrounding environment: this label is therefore destined to get worn and damaged over time, compromising its legibility and the aesthetic effect thereof.
  • This article in a case where it is not a single-use object but a durable article for daily use, such as for example a salad bowl or a common container for foods, will be subjected over time to repeated hand-washing and in dishwashers which will determine, inevitably, scratches and loss of colour on the label which will compromise the aesthetic appeal of the article.
  • the aim of the present invention consists in providing a process for realising, by injection moulding, an article with an informative/decorative/illustrative label which obviates the above- mentioned drawbacks.
  • the aim of the invention is to provide a process for realising an article with a label which is such as to guarantee, over time, the integrity and resistance of the label to any phenomenon or circumstance of deterioration or damage.
  • a further aim of the invention is to provide an article with a label obtainable with the above-cited process, in particular an article with a label that can be usable for containing/packing food articles or products in general.
  • the aim is obtained with an article with a label according to claim 11.
  • - figure 1 illustrates, in section, a first mould element and a second mould element usable for carrying out the process of the invention
  • - figure 2 illustrates, in section, a support element bearing a label and the first mould element, in a step of the process of the invention
  • - figures from 3 to 8 illustrate, in sequence, details of the carrying out of the process of the invention, for realising an article with a label according to a preferred and possible embodiment thereof;
  • - figure 9 illustrates, in perspective, an article with a label which can be obtained following the process of the present invention;
  • an article (1 ) which can be obtained using the process of the invention is a container for foods or products in general.
  • the process for realising an article (1 ) with a label (6) by means of injection moulding comprise steps of:
  • thermoplastic material a first die (4) sealedly closable for injection of a thermoplastic material, the first die (4) having a shape such that, when sealedly closed, an empty space is afforded therein for injection of a thermoplastic material;

  • IML label (6) comprising at least a printed portion (16) having graphic decorative images and at least a support layer made of a thermoplastic material chemically compatible with the first thermoplastic material (5).

  • thermoplastic material (5) heated so as to become a fluid and injected internally of the first die (4) so as to fill the empty space of the first die (4).
  • the first thermoplastic material (5) is cooled (for example by cooling means included in the first die (4)) so that it solidifies and the support layer of the label (6) chemically adheres thereto.
  • an intermediate article (8) is obtained, comprising a surface having at least a portion (9) on which the label (6) has adhered.
  • the process involves providing a second die (1 1 ) sealedly closable for injection of a thermoplastic material, the second die (1 1 ) having a shape such as to receive and contain internally thereof the intermediate article (8) and such that, when sealedly closed about the intermediate article (8), an empty space for injection of a thermoplastic material is afforded between the second die (1 1) and the intermediate article (8).

  • the second thermoplastic material (12) is cooled (for example using cooling means arranged in the second die (1 1 )) so that it solidifies and so that it chemically adheres at least to the first thermoplastic material (5) which forms the intermediate article (8) in order to obtain an article (1 ) with the label (6), which label (6) is interposed and closed between the solidified first thermoplastic material (5) and the solidified second thermoplastic material (12).
  • the process advantageously enables obtaining an article (1 ) having a label (6), which label (6) remains completely enclosed, interposed and protected between the solidified first thermoplastic material (5) and the second solidified thermoplastic material (12), and which label is therefore resistant to and protected from any phenomenon or circumstance relating to deterioration or damage (such as for example washing and impacts with other articles).
