Definitions

  • the present invention relates to a packaging for solid or pasty filling material which has a tendency to sit or stick to the packaging material and relates in particular to the closure part of this packaging.
  • the packaging is primarily intended for fats and fatty foods, especially margarine.
  • the packaging and the closure part can be made of any suitable material and also any common shape such as Have a box, mug, bowl, etc. However, the material of the closure part should be impermeable to the contents on its side facing the contents and should be permanently deformable.
  • Known packaging materials such as aluminum and plastic films, as well as cardboard coated with plastic can be used.
  • FR-A-1 157 785 describes a packaging in which a plastic film as a cylindrical outer surface surrounds a soft, plastic mass.
  • the film is embossed in a pattern that results in a decoration of the surface of the mass.
  • the film can be bent up to 180 ° and then peeled off like a skin from the mass without wrinkling, without damaging the decorative pattern on the mass.
  • a relief e.g. produced in the form of a flower on a soft margarine using a container that serves as a shape.
  • a thin and very flexible film is inserted between the container and margarine, which can later be removed from the shaped surface of the margarine.-These solutions cannot be used for closure parts for cups, bowls and cartons, since these closure parts are made of less flexible material and mostly are provided with edges that hinder a sufficient bending.
  • the surface of the closure part facing the filling material is provided with a large number of individual and independent recessed parts, cups, dimples or the like. (hereinafter referred to as "depressions"), which are separated by ribs or surfaces and are arranged and shaped such that air or another gas is enclosed when the closure part is placed and pressed on, as a result of which the filling material does not fill these depressions.
  • the closure part provided with the depressions can be the lid of a bowl or a cup formed from an aluminum or plastic, a separate strip of this material, which is placed on the contents under a lid, or above a removable wall surface of a folding box made of plastic coated Carton.
  • the ribs or surfaces between the depressions result in an imprint on the top of the filling material, which is retained when the closure part is removed.
  • the shape of the individual small elevations on the top of the content shows that these elevations have not filled the depressions of the closure part.
  • the shape, size and arrangement of the depressions according to the invention can be varied to a large extent.
  • the possibilities given by the packaging material for the formation of the depressions, the properties of the filling material and, if applicable, also the methods for placing and pressing on the closure part must be observed.
  • the surface of the ribs or surfaces which run continuously between the depressions and which are directed against the filling material is up to 90% of the total surface of the closure part placed on the filling material.
  • the open area of a depression can have a size of 1 mm 2-30 mm 2 , this open area being measured approximately in the plane of the surface of the connected ribs or areas.
  • the maximum depth of the depressions is preferably 0.15-1.5 mm, but may also be greater if necessary.
  • the depressions can have any cross-section and can be, for example, round, oval, square or triangular.
  • the closure part of the packaging consists of a plastic film into which depressions are embossed at least on its surface to be placed on the filling material.
  • the embossing can, for example, take place in a known manner immediately after its production on a suitable calender. With polystyrene foils produced in this way and placed on top of margarine immediately after filling in trays, it was found that almost no margarine stuck to the top sheets.
  • the depressions, or the ribs connected between them were produced by deep drawing. It is advantageous to carry out the deep-drawing of the surface of the closure part to be placed on the filling material for lids for cups or bowls simultaneously with the other usual deformations of the lid. This results in a corresponding pattern on the outer side of the lid. In this case, the material for the lids is printed before deep-drawing. Both the depressions to be produced by embossing and deep-drawing in the closure parts can have an open area of 1 mm 2 to 25 mm 2 .
  • Another version has depressions that are approximately oval and have an open area of 0.8 x 0.1 mm to 2.0 x 0.5 mm. These depressions were arranged in rows next to each other and with an alternating longitudinal direction.
  • a pattern of depressions of the type described above results, for example, when a wire mesh is pressed onto a packaging material.
  • embossing with a wire mesh care must be taken that the individual indentations which are pressed in are essentially not in contact with one another, but are separated from one another by ribs or surfaces which are not embossed.
  • Such a way of making depressions is particularly suitable for cardboard material coated with plastic.
  • a packaging according to the invention which consists of a folding box and a lid, the depressions are at least stamped into the side of the lid to be placed on the contents.
  • Fig. Shows a section of a deep-drawn film
  • Fig. 2 shows a section through part of a cup with a deep-drawn lid
  • Fig. 3 shows a section through a film with depressions, which were produced by embossing
  • Fig. 4 shows a section through a cardboard material provided with depressions
  • Fig. 5 shows a folding box
  • FIG. 1 shows the side of a thermoformed film made of polystyrene or polyvinyl chloride to be placed on the filling material.
  • the film is, for example, 0.2 mm thick.
  • a number of depressions 1 have been created by deep drawing, between which continuous ribs 2 run.
  • the depressions have an open rectangular cross section in the plane of the ribs 2 of a x b and a depth relative to the plane of the ribs of t.
  • the width of the ribs is denoted by s.
  • the side walls 3 of the depressions 1 run at an angle of approximately 60 ° to the plane of the ribs 2.
  • the edges between the surfaces of the ribs and depressions can also be slightly rounded.
  • FIG. 2 shows a deep-drawn cup lid 10 on a cup 11 which is filled with margarine 12.
  • the lid 10 lies with the ribs 2 on the margarine and penetrates a little into its surface.
  • the side walls 3 run at an angle of 45 °. Air cushions form in the depressions 1 and are separated from one another by the contact of the ribs 2 with the surface of the margarine 12.
  • Lids which were deep-drawn from a film of 0.2 mm thickness and had patterns according to FIGS. 1 and 2 were placed on margarine beakers, which was an opening cross section of about 12.5 x 8.5 cm with rounded corners.
  • the depressions 1 had the shape of square truncated pyramids.
  • the lids were mechanically placed on fresh margarine. After storage at 15 ° C for 3 and 6 weeks, the lids were removed.
  • Table 1 shows how much margarine stuck to the removed lids in samples of different dimensions.
  • the margarine that was still present in the lids with recesses was mainly in the vicinity of the lid edges, where the surface of the margarine had apparently been pushed aside by the lid.
  • FIG. 3 shows a film 22 into which square depressions 21 are embossed.
  • the film had a thickness d of 0.35 mm and the depth of the impressions was t equal to 0.15 mm.
  • the edge length a of the impressions was 1 mm and the width of the webs s remaining between the depressions was 0.5 mm.
  • the folding box 34 shown in FIG. 5 has a hinged lid 35, on the inside 36 of which the contents 37 adhered.
  • the lid was therefore difficult to open.
  • the adhesion could be significantly reduced by a pattern embossed on the inside 36 of the cardboard material (32), which is indicated in FIG. 5.
  • FIG. 4 shows a section through this cardboard material.
  • the wire mesh used in this example had a mesh size of 1 ⁇ 1 mm and a wire thickness of 0.35 mm and gave about 64 depressions per cm 2 .
  • the use of other wire grids also showed that less force was required to open the package and less margarine stuck to the lid. With these patterns too, the embossing may only take place to such an extent that the depressions 31 do not have a connection with one another. Lid surfaces in which the depressions 31 were connected to one another gave no better result than smooth lids.
