Definitions
- the present invention relates to a process for the production of sealed packaging of the closed envelope type with a lid and each containing a food product, in particular a liquid or pasty product, an installation for carrying out this process, and such packaging capable of be obtained by this process.
- the invention applies more particularly to mini-portions of fresh or melted cheese, mini cubes of broth or mini breads of butter, without limitation.
- a major disadvantage of the known methods of sealing these packages for liquid or pasty mini-portions therefore lies in the need to perform the sealing at a temperature related to that of hot dosing of these mini-portions.
- step d) is implemented by folding the flaps on the outer face of the lid, then sealing tightly under pressure these flaps on this outer face via an induction heating applied to the envelope, this sealing being obtained by hot activation of at least one adhesive provided at the sealing interface between the inner face of the envelope and the outer face of the lid.
- the sealing of the envelope and the lid used in step d) around a liquid or pasty product is not due to the hot dosing temperature of this product, but to the induction heating subsequent to this dosage combined with the application under pressure of the flaps of the envelope on the lid.
- this step d) of sealing according to the invention can advantageously be carried out in a very short time thanks to induction heating (fast start due to a lack of thermal inertia), with power densities and therefore a yield that can be very high.
- this induction heating guarantees the reproducibility of the sealing operations performed.
- the sealing operation which follows the folding of the flaps on the lid is accompanied by a tamping of the underlying food product.
- the envelope is coated on its inner face with a first heat-activatable adhesive, the lid being coated on its outer face with a second hot-activatable adhesive identical to the first adhesive or different of the last.
- step d) said adjacent folded portions of the envelope, for example in the form of bellows, by pressing them on each other during this induction heating. by hot activation of said first adhesive.
- step a) may further comprise, before step a2), a step of sealing on the inner face of each blank of at least one fusible opening strip of each package designed to open it by separation. on either side of a predetermined tearing direction via a gripping tab provided at the end of this strip, which has been previously cut to dimensions corresponding to those of each blank.
- each opening strip of each package may be advantageously metallized and coated with a third heat-activatable adhesive which is identical to one and / or the other of said first and second adhesives, for the heat-sealing of this strip on the envelope.
- hot-activatable adhesive that can be used on the envelope, the cover and on the or each heat-sealing strip of the package according to the invention, mention may for example be made of varnishes, commercially available hot melt glues and heat sealable heat sealable coatings.
- step b) can comprise a cold dosage inside the envelope of said product, which is of liquid or pasty type, this dosage being advantageously carried out at a temperature below 30 ° C and for example between 8 and 12 ° C in the case of fresh cheese.
- the induction heating can be performed in step d) immediately above each cell containing the envelope provided with the lid and, optionally, laterally on either side of this cell.
- a sealed package according to the invention which contains a food product in particular of the liquid or pasty type and which comprises an envelope receiving and laterally surrounding the product and a lid surmounting the latter, the envelope and the cover being both based on metal materials for example aluminum-based, is obtained by the manufacturing method according to the invention as defined above.
- the packaging according to the invention is necessarily based on metallic materials, in order to be obtained by this process involving induction heating of this packaging.
- This package according to the invention is such that the envelope comprises by folding a bottom and side walls delimiting an opening opposite to the bottom which is substantially closed by the lid, these side walls having adjacent portions folded on themselves and ending with flaps sealingly sealed to the outer face of the seal, at least one heat-activatable adhesive, such as heat-sealable varnish or hot melt glue, being provided at the sealing interface between the inner face of the seal envelope and this outer face of the lid and on the inner face of said folded portions to seal two by two these.
- at least one heat-activatable adhesive such as heat-sealable varnish or hot melt glue
- this packaging according to the invention may further comprise at least one heat-sealing strip for opening the package designed to open it by separation on either side of a predetermined direction via a gripping tab provided for end of this strip, which is heat sealed on the inner face of the envelope and is partly metallized.
- the packaging according to the invention may advantageously contain a mini-portion of a dairy product, such as a fresh or melted cheese, for example, and this regardless of the process for preparing these mini-portions.
- the side walls of the envelope may be of substantially polygonal section (for example rectangular, square or triangular) or of rounded shape (for example circular), and that the grammage used may vary from 10 g to 500 g with dimensions of the envelope corresponding to the selected grammage.
- this installation may comprise means for transferring / conveying the various elements of the linear and / or rotary type.
- the method of packaging the mini-portions 8 can be implemented as follows.
- the film 2 of the coil 1 is unwound, its inner face 2a upwards (intended to form the inner face of the envelope 5, 5a, 5b) so that it receives the strip or strips (s). ) 9, 9a, 9b.
- This inner face 2a is 100% or full-coated with a heat-activatable adhesive (for example at about 65 ° C.), such as a heat-sealing lacquer which is of course intended to be compatible with the foodstuffs and in addition with the hot-activatable adhesives 9A and 9D covering both sides of the opening strips 9, 9a, 9b and the covers 6, 6a, 6b.
- a heat-activatable adhesive for example at about 65 ° C.
- the strip or each strip 9, 9a, 9b is cut beforehand by the cutting means 11, and is then deposited by heat-sealing it at a temperature of, for example, between 120 and 140 ° C. on the internal face 2a of the film 2. by ensuring that a strip end 9, 9a, 9b protrudes from the film 2 by forming a gripping tongue to allow the packaging 7, 7a, 7b to be opened by the consumer.
- the blank 4 has a substantially octagonal shape admitting two axes of symmetry X and Y perpendicular and the strip 9 is fork-shaped with two branches.
- the blank 4a is substantially pentagonal, formed of an isosceles triangle whose base is extended by a rectangle, and the strip 9a is rectilinear along the median of greater length of this rectangle.
- the blank 4b is substantially octagonal (admitting an axis of symmetry Z and with rounded corners), and it is coated with two strips 9b crossing on this axis.
- the forming unit 14 is used to fold each blank 4, 4a, 4b in a folding box provided for this purpose, each envelope 5, 5a, 5b thus formed being then placed in a cell 17 of the unit. filling, sealing and sealing 16 of these envelopes.
- the casing 5 obtained includes portions P folded on themselves which are intended to be heat-sealed during the final step of sealing the casing 5 by induction.
- the mini-portions 8 are then metered into the envelope 5, 5a, 5b housed in each cell 17, ie between 8 and 12 ° C., for example in the case of fresh cheese using a "cold” technology, or between 72 and 82 ° C for example according to a "hot” technology.
- the film 3 is unwound from the reel 20 in order to obtain the lids 6, 6a, 6b, the sealable face 3a of this film 3 (ie the outer face 3a of the lid) being oriented upwards.
- This face 3 is coated at 100% or full face with a hot-activatable adhesive 6 'at about 65 ° C., for example, such as a lacquer or clear lacquer (visible at figure 12 ) compatible with the food and with the adhesives of the envelope 5, 5a, 5b and those 9A, 9D of the strips 9, 9a, 9b.
- this operculum film 3 may for example have a thickness of the order of ten microns, like the envelope film 2.
- This film 3 is cut by means of the cutting means 21, so that the shape and the dimensions of each lid 6, 6a, 6b obtained correspond to those of the opening of the envelope 5, 5a, 5b corresponding, then each cap 6, 6a, 6b thus obtained is deposited on the mini-portion 8 by exerting sufficient pressure on the mini-portion 8 until the upper surface of the latter is equalized.
- the following step consists in making the folding by tamping (for example under approximately 1 bar) of the upper flaps 5 'of each envelope 5, 5a, 5b (these flaps 5' are, for example, four in number for the envelope 5 according to the figures 3 and 13 ) on the outer face 3a of the lid 6, 6a, 6b corresponding.
- the mini-portions 8 respectively packaged in packages 7, 7a, 7b are sealed tightly, in a simple manner and in a very short time.
