Definitions

  • the present invention refers to a device for performing the complete emptying of the contents of the packaging containers of pourable food products, of different densities, such as UHT milk, fruit juice, fried tomato, etc., which are marketed in containers made of laminated materials.
  • the object of the invention is to allow the resealable systems used for the opening and closing of these containers to be able to pour the entire content of the liquid products they contain, since these containers, once used, continue to accumulate a significant amount in their interior. of the food product they contained.
  • the proposed system allows an improvement in the recycling of the elements that make up this type of packaging, helping to make the separation between the plastic of the resellable opening systems and the rest materials that form the body of the container.
  • the invention focuses on disposable containers for packaging liquid food products, the use of which is very widespread at present, which can be subsequently recycled.
  • These containers are manufactured from a laminated material, usually with a paper or cardboard core, covered on both sides with thermo-sealed plastic material, usually polyethylene, sometimes with an interlayer of light and oxygen barrier material, generally aluminum, separated from the product contained in the container by another layer of plastic material.
  • thermo-sealed plastic material usually polyethylene, sometimes with an interlayer of light and oxygen barrier material, generally aluminum, separated from the product contained in the container by another layer of plastic material.
  • Said containers are manufactured in automatic packaging machines from strips of the laminated material.
  • a very widespread system for the manufacture of containers consists in transforming the strip of material into a tube joining and sealing together the two longitudinal edges of the strip in a superposed longitudinal connection.
  • the tube thus formed is filled with the product previously sterilized and divided into units, by sealing and subsequent separation by cutting along transverse sections of the tube to form pillow-shaped containers to which it is folded mechanically to give them the final desired shape.
  • the shaping of the containers is carried out by means of different folding and closing actions of the laminated material by means of which four triangular-shaped lugs are obtained at each of the ends of the pillow-shaped containers.
  • the upper lugs are folded and glued on the adjacent side walls, while the lower lugs are folded and glued to the base of the container.
  • These containers generally have a flat upper face, parallel to the base, or inclined thereto, which is referred to as a "water cover”.
  • Another type of forming that can be given to the strips of laminated material consists of previously cutting them into preformed pieces and using the appropriate machinery to fold them and shape them into containers, sealing the base and leaving the upper part open to be subsequently filled with the food product.
  • the closing operation is performed by means of sealing and bending the finishing seam or the edge seam by thermal sealing or ultrasonic welding.
  • the containers thus formed generally have their upper part in the form of gable or "gable roof", although by this system can also be made flat top or inclined containers with "cover to a water” as obtained by the above procedure.
  • the containers of "cover to two waters” were designed initially to be able to open by means of the unfolding of one of the lateral superiors of the container. To open them, the end seam is detached until halfway, the inner fold separates from the sides and is moved to the outside of the container. In this way an emptying element of the contents of the container is achieved in the form of a peak that facilitates the pouring of it.
  • These containers allow the formed peak to be folded back and returned to its original shape. The partial closing of the container is thus achieved, but the entry of air inside it or the pouring of the contents in case of excessive falling or tilting of the container is not prevented.
  • opening holes are easily manufactured and do not require additional equipment for this.
  • the drawback is that the opening holes thus obtained provide irregular and frayed rip edges at the perimeter of the opening which causes its rapid degradation by contact with the contents of the container and the consequent absorption of liquids by the fibrous material of which They are formed.
  • the contours of the pouring orifices are wetted and quickly lose the consistency necessary to carry out the pouring under the right conditions.
  • Another widely used container opening system is to provide them with an opening hole in the upper part of the main body of the container.
  • This hole is made by punching the laminated packaging material described above.
  • To seal the exit orifice it is covered by a tongue along the outer perimeter of the exit orifice and also with a tape on the inside of this hole.
  • the outer tab and the inner tape are joined by fusion to each other to ensure the sealing of the exit orifice.
  • To open the container simply pull up one end of the tab so that the seal formed between it and the internal tape is broken and leave the pouring hole open. Once opened, this system does not allow the closure of the outlet of the container.

  • this type of container only the complete emptying is achieved if said edge is completely horizontal in the pouring position, which is difficult for the user to achieve.

Abstract

Dispositif permettant de vider complètement les contenants fabriqués dans un matériau multicouches comprenant généralement un noyau de papier ou de carton recouvert sur ses deux faces de matière plastique thermosoudée, généralement du polyéthylène, utilisés pour contenir des produits alimentaires fluides, qui comprend un série de lignes de rupture (5) formées par des incisions réalisées dans les couches externes du matériau multicouches formant le contenant (1), qui soit partent des côtés du pourtour interne de l'orifice de distribution (4) du contenant, soit entourent le pourtour du système d'ouverture (2) du contenant et convergent au sommet (3) ou optionnellement vers l'angle le plus proche (8) du contenant (1), ou sont optionnellement disposées perpendiculairement à un des angles latéraux (10) du contenant (1). L'invention est mise en oeuvre soit par une action du consommateur sur le système d'ouverture refermable (2), le déplacement de ce dernier en direction du sommet (3) ou de l'angle (8) de distribution entraînant une séparation partielle du système d'ouverture refermable (2) du contenant (1) et/ou une rupture des lignes de rupture (5) grâce à un assujettissement assuré par le biais de perforations (7), et la séparation subséquente du système d'ouverture refermable (2) du contenant (1), soit par une pression appliquée par le consommateur sur les lignes de rupture (5) à l'aide du système d'ouverture refermable (2) modifié, une fois que celui-ci est séparé du contenant (1), et qui est pourvu à cet effet d'un élément coupant ou perforant (9). Dans les deux cas, une ouverture permettant l'extraction de la totalité du liquide contenu dans l'emballage est créée.
