Definitions

  • the present invention relates to the field of packaging; she relates more particularly to a method of setting up a volume sealed container from a cardboard blank, as well as the container waterproof obtained by the process.
  • Certain food products, and in particular meats of the type poultry, steak, liver or other ... are usually packaged in packaging in the form of trays associated with a plastic film of protection.
  • These trays are generally made of material of the kind polystyrene; their manufacturing cost is relatively low but they have the disadvantage of being neither biodegradable nor recyclable.
  • cardboard trays have been proposed which consist of a generally rectangular bottom, bordered by four side walls. Sealing at the corners is ensured by bellows folded against one of the side walls and held in position by gluing. These bellows are made in two parts of generally triangular shape. To maintain the volume, one of these parts is glued to the front and the other to the back, depending on their positioning inside or outside the tray. This double sizing complicates the automatic assembly process of the trays. This complexity requires the use of expensive assembly machines and limits the rates of volume setting.
  • a liquid-tight cardboard container is described in document US-A-1 959 613. Its corners are equipped with two-part bellows, one of which has an opening or cut-out to allow direct contact between the other part of the bellows. and the receiving side. This feature gives the possibility of gluing only one side of the cardboard blank to maintain the volume of the packaging.
  • the bellows are folded down on the outside to avoid the presence of internal folds and not to present, in the internal volume, a cut blank edge which would absorb liquids. Given the anti-leak destination of this container, for packaging liquids for example, it is therefore essential to position the bellows on the outside.
  • this structure promotes the passage of liquids between the two bellows parts.
  • the liquid has the possibility of rising by capillary action and it quickly enters the thickness of the cardboard through the upper edge, causing a splitting of the constituent material, a collapse of the packaging and the flow of the contents.
  • the presence of the exterior bellows makes this type of packaging unattractive.
  • document US-A-4 304 352 provides, for a similar structure, recto bonding. -back.
  • the upper cutout of one of the bellows parts ensures the bonding of the other bellows part on the receiving side to improve resistance to level of angles; it also facilitates volume setting in the corners, in connection with the presence of a receiving edge with a sealed cover.
  • Document EP-A-0 178 730 also describes a folding tray consisting of a bottom bordered by four side walls of great depth. In the corners, bellows in two parts folded inwardly provide sealing; the first bellows part has an upper cutout which allows direct contact between the second bellows part and the receiving side wall. The first part of the bellows, that is to say that which includes the upper cutout, extends over approximately 80% of the height of the plate.
  • This folding tray also has a peripheral rim on which is positioned a cover which, in addition to its sealing function, maintains the volume of the assembly. The ⁇ folding ⁇ aspect of this tray complicates the volume setting process.
  • the structure of the sealing bellows does not allow bonding of the second part of the bellows, that is to say that which does not include the upper cutout, over a large area.
  • the object of the present invention is to remedy these various disadvantages.
  • the cardboard tray obtained by the process which is the subject of the present invention is intended for the packaging of food products from like chicken thighs, steak or other ... likely to exude from small volumes of liquids.
  • the purpose of this tray is to contain these small volumes of liquids and therefore has properties sealing, especially at the corners of the bottom, adapted for avoid capillary liquids rising; it is also obtained in a very simple way and likely to be volume, by automatic means, at very high rates.
  • the invention also relates to the sealed container obtained by the process defined above.
  • This tray structure requires sizing in areas fitted on one side of the cardboard blank, allowing the use of relatively simple automatic assembly lines.
  • the bonding of the folded bellows inside the tray achieves an effective joining at the angles which prevents liquids from going up by capillary action to the edges of the cardboard blank, at the top cut in one bellows parts, or at the upper edge of the tray.
  • the gluing is carried out by two points glue; the first on the transition line between the two parts of bellows plated on their lateral receiving side, and the second in the upper part to secure the bellows part without cutting.
  • the first point of glue blocks or stops the possible ascent of liquid by capillarity and prevents them from reaching the slices of the tray.
  • the tray structure according to the present application with folded bellows on the inside also gives to the finished product an integrity external appearance allowing printing advertising messages on a surface without roughness.
  • Figure 1 is a flat view of a cardboard blank can be set in volume to obtain a tray waterproof.
  • This blank 1 consists of a rectangular bottom 2 bordered by two large lateral sides 3, 4 and two short end side sides 5 and 6, having substantially identical heights.
  • Sides 3, 4, 5 and 6 have a substantially trapezoidal shape for obtaining a trunk of pyramid container; they are connected two by two by angle bellows 7 intended for seal at least in the bottom of the tray and adapted to avoid liquid rising by capillarity.
  • the four bellows 7 are identical and made up each of two parts 8 and 9, of general shape triangular, separated by a center fold line 10.
  • the first part 8 of the bellows 7 is attached to the corresponding small lateral side 5, 6. It extends from the bottom 2 at a height less than that on the lateral side 5, 6 adjacent, so as to form a opening or cut 11 in its upper part.
  • the border upper 12 of triangle 8 extends substantially perpendicular to the edge of the adjacent lateral side, from mid-height on this side.
  • the second part 9 of the bellows 7 is attached at the long side 3, 4 corresponding; She's spreading substantially over the entire height of the latter. Its angle free 13, linked to the presence of the cutout 11, is truncated to avoid having to handle a piece of cardboard with too tight angles.
  • the internal face of the blank 1, at least, has undergone waterproofing treatment that removes or at least limit the penetration to the heart of moisture from packaged products.
  • the volume of the tray is made up of automatically by appropriate mechanical means.
  • This volume is achieved by folding down the two parts 8 and 9 of the bellows 7 against the faces internal, either short sides 5, 6, or long sides 3, 4, as appropriate. This choice is conditioned by the dimensions of the tray and according to techniques used if it is covered with plastic film stretchable. In the present case, the bellows 7 are folded over the inner faces of the short sides 5 and 6.
  • the bellows arranged inside the tray ensure quality aesthetics and they do not interfere stacking of products in each other, under reserve to provide a taper (to be determined according to desired end result). On the other hand, they allow exterior marking (advertising, decoration, information %) on a smooth surface, without roughness.
  • the first stage of assembly consists in gluing the lateral areas of the inner side of the short sides 5 and 6, on which the two parts will be pressed 8 and 9 bellows. This gluing can be done on the entire hatched area 14, or be defined by dots of adhesive, arranged judiciously, of the as described later.
  • the next step is to raise the side sides 3, 4, 5 and 6 by placing the two parts 8 and 9 of the bellows of angles 7 against the lateral receiving side 5, 6.
  • the front of the first part 8 bellows is pressed against the lower area gluing; in addition and thanks to the presence of the cutout 11, the back of the second bellows part 9 comes press against the upper gluing area.
  • the sizing is obtained by means of two glue dots 15 and 16, aligned vertically on the gluing area 14.
  • the point of glue 15 is placed at the top edge 12 of the first bellows part 8; he blocks the transition line between this first part 8 and the second part 9 of bellows. In addition, it prevents the rising humidity by capillary action.
  • the second point glue 16 is placed in the upper part; he secures the inner side of the short side 5, 6 with the second part 9 of bellows.
  • glue dots additional can be added.
  • the gluing can be done by buffer in order to obtain a larger bonding surface.
  • Gluing is carried out on only one side of the blank, the volume setting of the tray, which follows this gluing operation, is carried out in a very simple way and very fast; mounting can be done at very high rates.
  • the particular mounting process allows blocking correct at the angles and good sealing of the bellows in the bottom of the tray.
  • the shape of the tray in a pyramid trunk, facilitates stacking of packaging, empty.
  • this shape it is quite possible to consider varying this shape, while retaining the same structure and same principle of assembly.
  • the lateral sides of the tray can be perpendicular to the bottom to obtain a parallelepiped packaging.
  • the bottom 2 can have any polygonal shape.
  • the cutout 11 produced in the upper zone of one of the parts of the bellows can be produced by any suitable means and be in any form.
