Definitions

  • the present invention relates to flexible packages for snack food items, especially, packages for drinkable or squeezable liquid food products that can be directly put to lips for consuming the food contained therein.
  • Liquid or wet food savoury snack food items such as milk-based, creamy products, sweet drinks, cereal or vegetable-based products, are air sensitive food that tends to rapidly become spoiled by microbiological growth if not packaged in proper conditions.
  • Liquid and wet food of this type is usually packaged in pouch or bags manufactured from flexible film material having oxygen-barrier properties. Examples of suitable materials include metal foils, thermoplastic films and combinations thereof.
  • the consumer deserves to have a hygienic contact to the food product at the time he decides to drink or eat it.
  • the packages are mainly intended to be used as snack products, in various conditions during daytime, it is very possible that the external state of the package dedicated to go into the mouth does not give good hygienic guarantees. It is a major obstacle against the commercial development of this type of food products.
  • the present invention overcomes the deficiencies of the present state of the art and satisfies the needs discussed above.
  • One of the main objects of the invention is to provide a package, adapted to snack food products which goes to the mouth; the package delivering the food product in satisfying hygienic conditions.
  • the present invention is a package for a snack food product comprising
  • the pouch remains well protected against spoilage, dirt, etc., until the consumer decides to eat or drink the food product contained within the package.
  • the protective member also guarantees to the consumer the freshness of the food product.
  • the protective member can also prevent from accidental or intentional opening of the pouch without real intention to consume the food product.
  • the protective member is a flexible mono- or multi-layer having moisture- and air-barrier properties.
  • the sheet of the pouch comprises an external surface onto which the protective member is sealed to form with the pouch a hermetically closed pocket in the region intended to be opened for releasing the product.
  • a tight seal permits to ensure that the package has not been manipulated beforehand. It is also an economical and simple way of manufacturing the package of the invention by the commonly known packaging techniques in the flexible packaging area.
  • Another important feature of the invention is to provide a protective member with a peelable connection to the pouch. Therefore, the protection can be easily and rapidly released from the pouch when decision has been made to eat or drink the product. The protection release can also be made separately from the opening of the pouch itself so if the protection of the opening is accidentally made, the pouch is maintained tight.
  • the invention also relates to the method of manufacturing the package of the invention, which comprises:
  • FIG. 1 illustrates in schematic fashion a snack food package of the invention.
  • the package identified by reference numeral 1, comprises a pouch 2 constructed from a single sheet of flexible material in accordance with known industry practice, such as by feeding roll stock over a former in a form-fill-seal apparatus.
  • the pouch could also be made of the assembly of several sheets of flexible material without departing from the scope of the present invention.
  • the pouch comprises a first end 20 and a second opposite end 21 longitudinally delimiting the pouch.
  • a protective member 3 covers the first end of the pouch and longitudinally extends along a certain length along the pouch.
  • the pouch is made of a single folded sheet along a longitudinal side fold 22. As illustrated in FIG. 4, the sheet defines two side edges 23a, 23b united to form a permanent seam 23, extending longitudinally substantially from the first end 20 to the second end 21 of the pouch. The seam 23 protrudes along an exterior longitudinal side of the pouch opposed to the side fold 22.
  • the sheet also has transversally oriented end edges, which are assembled to form a first permanent transversal seam 25 and a second transversal permanent seam 26.
  • the pouch comprises a printed tear-off line 28 oriented along the whole width of the pouch in the vicinity of the first end, as best shown in FIG. 2 and FIG. 3.
  • a small notch 29 provided partly in the longitudinal side seam 23 so as to provide a suitable tearing start.
  • the tear-off line 28 is not a line of weakness provided in the film material itself, but merely a printed indication of the direction of opening the pouch.
  • the direction of the line takes into account the normal orientation of the material.
  • the orientation of the tear-off line could also be slightly different depending on the specific orientation of the packaging material.
  • FIG. 3 and FIG. 4 show details of the protective member 3, which covers the tip of the pouch.
  • the protective member 3 forms a cover surrounding circumferentially the pouch 2.
  • the protective member is preferably sealed on the external surface of the sheet, which forms the pouch.
  • the protective member has a substantially rectangular configuration which surrounds the pouch and ends laterally by two side edges 31, 32 connected on the pouch surface with peelable longitudinal sealing cords 40, 41.
  • the protective member extends longitudinally along the pouch to ends by two opposite transversal edges 33, 34, spaced apart one another, and attached to the pouch surface with peelable transversal sealing cords 42,43. Therefore, the sealing cords 40, 41, 42, 43 define the limits of a hermetically closed pocket 5.
  • the side edge 31 of the protective member extends by a tongue 35 protruding outwardly which permits the protective member to be easily removed by tearing-off the peelable connections.
  • FIG. 5 shows the pouch after the protective member has been removed.
  • the permanent seams 23, 25, 26 are formed by using any of a variety of methods known in the art including heat welding the two surfaces of the sheet together, or uniting the surfaces by applying a sealant or permanent adhesive therebetween.
  • the choice of a sealing method is based on the composition of the sheet material. Heat sealing is usually least expensive, least time consuming, and therefore preferred.
  • the protective member is sealed along the peelable sealing cords 40, 41, 42, 43.
  • These cords are also formed by using any of a variety of methods known in the art including heat welding the surface of the protective member onto the surface of the sheet, or uniting them by applying a sealant or releasable adhesive therebetween.
  • the sealing cords allow the protective member 3 to be easily removed from the pouch 2 without damage to the pouch itself.
  • the strength of the peelable sealing cords has to be lower than the strength of the permanent seams of the pouch so as to maintain the integrity of the seams and prevent any accidental lack of food product from the pouch.
  • connection of the protective member be waterproof.
  • the connection can withstand a range of temperatures for sterilisation or pasteurisation of the pouch. More preferably, the connection must withstand a temperature ranging up to 135 ° C. Indeed, it is important that no water comes into the pocket 5 otherwise it would loose its hygienic properties.
  • FIG. 6 to 9 presents a second possible embodiment of the invention.
  • the pouch 2 comprises a front side 50 and a rear side 51.
  • the pouch further comprises two side edges 23a, 23b united to form a permanent seam 23 located substantially along the rear side 51 of the pouch.
  • the permanent seam 23 forms a flap of the flexible material, which is folded against the exterior surface of the pouch rear side 51.
  • the protective member 3 also forms a cover surrounding the circumference of the pouch.
  • the protective member has two side edges 31, 32 connected to the external surfaces of the respective side edges 23a, 23b of the pouch by means of peelable connections 40, 41 .
  • the protective member comprises two opposite transversal edges 33, 34 attached to the pouch exterior surface with circumferential peelable connections 42, 43.
  • the peelable connections 40, 41, 42, 43 make a similar closed continuous attachment to the pouch so as to define a tight pocket 5.
  • the main benefit of this embodiment resides in respecting the usual location of the flap, substantially in the middle of the rear side of the package, therefore, minimising the risks of cutting the mouth compared to a side positioned seam as in the previous embodiment.
  • the longitudinal position of the seam 23 can vary with respect to the lateral folds of the pouch. Therefore, the seam may also be off-centred with respect to the theoretical middle line of the rear side 23 so as to be closer to one of the lateral folds of the pouch
  • the protective member does not extend the all length of the pouch essentially for economical and practical reasons.
  • the length of the protective member must also be sized to cover the effective portion of the pouch, which is intended to be put into the mouth. Therefore, the protective member extends longitudinally along a length comprised between 1:10 to 1:2 of the total length of the pouch.
  • FIG. 10 and 11 shows a preferred manner to manufacture the snack food package of the invention.
  • the sheet material 6, for example is fed from roll stock 7 and placed in a flat configuration.
  • Protective members 36, 39 are then applied onto the surface of the sheet material so that hermetically closed flat pockets are attached tightly to the sheet surface. It is essential that no air be entrapped within the pocket to prevent any risk of burst during following sterilisation of the package.
  • the protective pockets are heat sealed to the sheet surface by an adapted heat-sealing device.
  • a continuous, peelable connection 4 is made so.
  • the connection has a substantially rectangular shape lining the edges of the protective member and forming connected sealing cords 40, 41, 42, 43.
  • two protective members are simultaneously disposed in an adjacent position onto the flat sheet surface. Therefore, the two protective members can be treated as one single sheet, which is so welded along two separate sets of sealing cords. Then, the sheet is cut apart during the subsequent forming-filling-sealing operation.
  • FIG. 11 illustrates the vertical forming-filling-sealing device 8 used as a preferred example for making the snack food package of the invention.
  • the sheet is fed over a former shoulder arrangement 80 to align the sheet in a tubular configuration.
  • the tube is filled by gravity by a dosing system (not shown) with food product through a "marine collar" 81.
  • the two longitudinal edges of the sheet are welded together to form the longitudinal seam by a vertical heating plate 82 (thermal heated or by electrical impulse).
  • the transversal seams are welded two-by-two and divided by a horizontal heating-cutting device 83. It is apparent to those skilled in the art that depending on the relative rotational configuration of the longitudinal welding device 82, it is possible to either manufacturing the embodiment of FIG. 1 to 5 or the embodiment of FIG. 6 to 9.
  • FIG. 11 is given as a processing example.
  • the choice of a filling-sealing method is based on the composition of the sheet material and the filled product.
  • a horizontally oriented device could replace the vertically oriented device for products, which comes in the form of substantially solid unitary elements.
  • the sheet material is preferably chosen among multi-layered packaging materials. Suitable materials include metallic foils, thermoplastic films, papers and combinations thereof. More preferably, the sheet material is a coextruded laminate comprising OPP (external)/Aluminium/Polypropene (internal). OPP especially means oriented polypropene. Examples of laminate thickness distribution are 20/9/30-70 microns.
  • the protective member is also preferably a mono- or multi-layer such as coextruded OPP/Polyethene, which gives a peelable seal when directly applied onto the pouch material.
  • the protective member can also be an adhesive label surrounding the tip of the pouch, forming an airtight protection; the label comprising, internally, a releasable adhesive to allow an easy removal.
