Definitions

  • the present invention relates to a package of the type comprising a pot delimited by a bottom and a peripheral dress defining an opening opposite the bottom.
  • a grout or topping is present at the bottom of the pot.
  • the user removes the sealing cap and returns the pot over a plate.
  • An air inlet is created in the bottom of the pot, either by removing a tongue initially closing a hole, or by breaking a frangible portion of the bottom of the pot. Due to the arrival of air, the blank is released in the plate and the topping contained in the bottom of the pot. Thus, the topping flows from the upper portion of the blank covering it aesthetically.
  • the topping is in constant contact with the blank during storage of the pot.
  • the two substances are in constant contact during the storage / transport phase which precedes the consumption phase. Indeed, the contact can affect the taste qualities of the product and / or its visual appearance.
  • the invention aims to provide a package for separate storage of two food substances and bringing them into contact, during a single phase of demolding allowing the release of the two substances and their bringing into simultaneous contact.
  • the subject of the invention is a package of the aforementioned type, characterized in that it comprises a frangible membrane disposed between the bottom and the opening, which frangible membrane is welded at its periphery to the inner surface of the pot and thus delimits, successively from the bottom to the opening, a lower housing and an upper housing initially separated.
  • the package 10 illustrated in Figure 1 essentially comprises a pot 12 having an upper opening end 14 initially closed by a removable cap 16.
  • the package 10 further comprises a frangible membrane 18 defining, in the pot, a lower housing 20 filled a first substance such as a grout and an upper housing 22 filled with a second substance such as a blank.
  • the membrane 18 extends generally transversely to the pot, that is to say parallel to the plane of the opening 14.
  • the pot 12 is, as known per se, formed by thermoforming from a sheet of plastic material such as polystyrene.
  • the pot has a bottom 23 surrounded by a dress 24 delimiting the body of the pot.
  • a sealing rim 26 of the cover 16 surrounds the opening 14 externally.
  • the dress has a generally frustoconical shape flaring from the bottom 23 to the upper opening 14.
  • the dress 24 has a transverse shoulder 28 formed near the bottom 22.
  • the dress has a lower section 30 connected by the shoulder 28 at an upper section 32, the sections 30 and 32 delimiting laterally, respectively, the lower housing 20 and the upper housing 22.
  • the bottom 23 has a reduced thickness allowing its elastic deformation, and in particular allowing it to bend towards the inside of the pot under the action of an axial pressure exerted at its center from the outside of the pot.
  • the membrane 18 has the shape of a disc. It is welded at its periphery to the intermediate ring delimited by the shoulder 28. It is welded in a weld defining a closed contour so that it initially seals the lower housing 20.
  • the membrane 18 is formed of one or more polymeric materials adapted for heat sealing on the shoulder 28 of the pot.
  • This weakening line 40 has a weakening line 40 allowing it to be frangible.
  • This weakening line extends over most of the width of the membrane and advantageously follows a curved profile, so that it delimits a tongue 42.
  • the weakening line delimits an open contour.
  • This line of weakness 40 is formed by treatment of the film constituting the membrane.
  • the treatment is applied before the introduction of the membrane in the pot while the film is being manufactured and before winding.
  • the weakening line 40 is produced by applying a high energy radiation, such as a laser, by applying a laser beam along the line of the line to be weakened. This high energy treatment is performed on one or more layers of the film when the latter comprises more than one layer.
  • the weakening line is formed by a mechanical weakening of the film which extends along the line of the weakening line. This mechanical treatment is carried out according to one or more of the layers of the film when it comprises more than one.
  • a microporous weakening is performed in order to form the weakening line.
  • a microporous treatment is obtained for example by passing the film or a layer of the film, when it comprises several of them, between two rollers, one of the rollers having a surface rendered abrasive in the zone to be applied on the line. to weaken.
  • Such a treatment is described for example in document FR-2.717.449.
  • the mechanical weakening is obtained by cutting or punching partially or completely the thickness of one or more layers of the film when the latter comprises more than one. These cuts or punchings are formed by applying a matrix of cutting blades along the line of weakness. During the treatment, the film is pressed between the matrix and a support, as known per se. Thus, the cut or partially cut portion is formed in dashed lines.
  • the line of weakness 40 is formed by a microperforated region that does not completely pass through the film but reduces the breaking strength of the film in the treated area. These micro-perforations can penetrate only through one of the layers of the film when it comprises several.
  • a combination of the weakening processes described above can be performed on the same film, or on the same layer of the film, or on different layers of the film if it comprises more than one.
  • FIG. 2 A particularly advantageous embodiment of the membrane is illustrated in FIG. 2.
  • This comprises several laminated or coextruded polymer layers.
  • it comprises a support layer 52 associated with a sealing layer 54, a connecting layer 56 being disposed between these two layers for their connection over their entire surface.
  • the support layer 52 is formed for example of a bi-oriented polyester and has a thickness of between 6 microns and 50 microns and preferably substantially equal to 12 microns.
  • the welding film 54 is chosen to allow heat sealing on the shoulder 28 of the polystyrene pot.
  • the welding film 54 is advantageously a polystyrene film, that is to say in the same material as that constituting the pot.
  • the thickness of the layer 54 is between 15 ⁇ m and 50 ⁇ m and preferably substantially equal to 30 ⁇ m.
  • the polystyrene layer 54 consists of more than 50% by mass of crystalline phase.
  • the crystalline phase is preferably greater than 80% by weight, and advantageously between 85% and 99% by weight.
  • a sealing varnish is applied to the surface of the film 54 to be welded to the shoulder 28 for melt-incompatible materials.
  • the layer 56 is formed for example of an adhesive providing a binding force sufficient to prevent delamination between the layers 52 and 54.
  • the layer 56 is formed of a polymer extrusion.
  • the support layer 52 comprises a weakening 52A made by a high energy radiation and in particular a laser beam. It is also possible to use a mechanical cut (rotary knife / blades / etc ...) of the support layer 52 before its combination with the sealing layer 54.
  • the solder layer 54 is devoid of any weakening treatment.
  • a weakening treatment 54A is provided along the line of the weakening line 40 in the solder layer 54.
  • This line may have different drawings depending on the viscosity of the product contained in the lower housing 20.
  • This treatment preferably consists in rendering the layer 54 embrittled along the path of the line of weakness 40, in particular by passing the layer 54 between two rolls, one of which is abrasive in order to roughen one of the surfaces of the layer 54
  • this surface is disposed on the side of the bonding layer 56.
  • the tensile rupture force of the membrane 18 along the line of weakness 40 is between 3 N / 15 mm and 50 N / 15 mm, that is to say it is necessary to apply a force of 3 N to 50 N transversely to a line of weakness 40 with a length of 15 mm to obtain the rupture of the membrane along the line of weakness. It is preferably between 4 N / 15 mm and 40 N / 15 mm.
  • composition of the membrane and the treatments carried out make it possible to adjust the rupture as a function of the pressure exerted on the bottom by the consumer, the surface of the membrane and the volume of the reservoir.
  • the seal 16 closing the package filled, for example, with a grout in the lower chamber and a blank in the upper housing 22 is formed of a composite film consisting for example of paper and a polymer film coated with a heat-sealing varnish, or a pre-cut foil-based seal.
  • the polystyrene pot 12 is first thermoformed. This is then filled with the topping arranged directly in the lower housing 20.
  • the membrane 18 is cut from coil or pre-cut beforehand, then placed and welded by heat-sealing on the shoulder 28.
  • the compatibility of the materials for ultrasonic sealing for example.
  • the blank 22 still liquid is poured into the upper housing.
  • the composition of one of the polymer layers of the membrane and especially, in this example, of the layer 54 makes it possible to resist the impact of the blank deposited on the membrane 18.
  • the cap 16 is positioned and welded on the flange 26, as known per se.
  • the cap 16 is removed and the pot containing the blank and the topping is turned over a plate with the opening 16 pressed on the bottom of the plate.
  • the pressure causes the fall of the blank that is received on the bottom of the plate.
  • the topping then flows gradually through the opening designated by the reference 70 in Figure 3 to flow on the blank from its top.
  • the tongue shape imparted to the broken membrane 18 by the curved weakening line allows easy flow of the batt, even if it has a certain viscosity.
  • the polyester layer makes it possible to ensure coherence for the pieces of the highly crystallized polystyrene layer 54, in order to prevent these pieces from mixing with the food product and thus to guarantee a lack of transfer into the food product.
  • the proposed packaging makes it possible to separately store two food substances and to ensure their contacting and demolding in a single operation.
