Definitions

• the present invention relates to a packaging of a food product, in particular of rectangular parallelepiped general shape such as a square of chocolate, or of an individual confectionery article such as a candy, a biscuit, a madeleine or a bar.
• the invention is also applicable to other individualized and packaged food products such as salted products.
• the invention thus relates to a packaging for a food product distributed in the general public, more particularly in cafes, brasseries and hotels to accompany the coffees served by these traders.
• the food product of this type most commonly distributed, free of charge with each cup of coffee, is an individual chocolate square accompanying a so-called "espresso" coffee, the packaging of which usually comprises a first food contact sheet that completely protects the chocolate square. , and whose external appearance is usually metallized or shiny, and an outer shell called "chocolate ring”.
• the outer ring consists of a longitudinal strip of rectangular shape of a material which is most often a rectangular sheet of paper and which, in the manufacturing and packaging process, is wrapped around the square of chocolate with its sheet of paper. food contact and which is then closed by gluing an area of the back of the band on a portion vis-à-vis the recto it covers.
• the ring-shaped band thus perfectly matches the shape of the food product, and in particular the rectangular parallelepiped shape of the chocolate, and its primary function is to keep the chocolate packaged in the first food contact sheet, avoiding any unwanted unpacking and for second function , to include on its front, that is to say on its face visible by the consumer, certain information such as for example the name of recovery which distributes the chocolates and other indications concerning the composition of the chocolate and its origin.
• the opening of the packaging for consumption is a particularly delicate operation requiring some dexterity of the consumer, in particular to allow him to catch any part of the ring to open it. In all cases, the opening results in tearing the ring.
• the invention also relates to a so-called "flow-pack" packaging commonly used in the field of the distribution of various food products, in particular confectionery articles.
• a "flow-pack” type packaging consists of a rectangular sheet of flexible material which is wrapped around the product, for example around the chocolate square or the madeleine, and which is closed by heat-sealing two zones opposite opposite longitudinal ends of the strip or sheet of material which is generally a sheet or film of plastic material, transparent or opaque.
• the closure of the paper sheet is ensured by gluing while, in the present case of the "flow-pack", the closure is provided on the one hand by heat sealing of the two sections of paper. opposite longitudinal end of the strip, but also by heat sealing the opposite horizontal edges, top and bottom, of the strip so as to constitute a sealed package.
• Packaging in the form of a "flow-pack” envelope is very important in the field of confectionery. Indeed, in addition to packaging chocolate squares or cookies, many chocolate bars or the like are thus packaged, individually or in multiple copies, for distribution.
• a candy wrapped in "papillote” in a strip of material such as paper has the same characteristics as a product packaged under "flow-pack", that is to say that its foil has two parts “flat” "end on both sides of the candy.
• the strip of material wound around the product is closed at least in two longitudinal end regions, high and low, and which is for example closed by fixing, especially by bonding or heat sealing, two zones vis-à-vis the two longitudinal ends, high and low, of the band.
• the invention proposes a packaging of a food product, such as a chocolate square, or a confectionery article such as a candy, a biscuit or a bar, which is packaged in a strip rectangular material which is wound around the product and which is closed at least in two longitudinal end regions, high and low, of the strip, characterized in that the packaging comprises: an outer jacket, made of rigid or semi-rigid material, comprising an upper sheet and a lower sheet interconnected by a rear vertical back, and which respectively extend facing opposite faces of the product; and means for retaining the product inside the liner.

• the retaining tongue 50 is adjacent to the upper face 18 or the lower face 16 of the product 1 0.
• the product 10 is retained in the vertical direction V to the extent that its opposite horizontal edges 52 and 54 are received inside. of the band 14, practically without play, thus opposing any vertical movement of the product 10 inside the jacket 32.
• the product 10 is retained in both directions horizontally to the left and to the right, firstly by the vertical strip 57 of the tongue 50 delimited by the edges 55 and 40 and, secondly, by the inner face 39 of the vertical back 38.
• the product 10 is retained in the direction T inside the closed jacket 32 to the extent that it is sandwiched between the lower sheets 34 and 36 with its lower face 16 adjacent to the inner face 37; its upper face 18 is facing the inner face 41 of the upper sheet 36.

• the latches 68 and 70 are shaped to facilitate locking and unlocking for opening.
• the packaging formed by the jacket 32 constitutes an ideal advertising medium, in particular by its large surface area.
• the product is perfectly maintained inside the jacket and this practically without clearance because of the pinch effect resulting from the closure of the jacket 32, especially when the latter has locking means in the closed position.
• the messages with advertising content may appear not only on the inner back of the jacket 32 constituted by the internal faces 37, 39 and 41 (here represented by the letters V), but of course also and preferably on the outer face of the shirt 32 constituted by the outer faces 37 ', 39' and 41 'of the shirt 32 (here represented by the letters R).
• the jacket 32 is after use (that is to say after opening for consumption of the product 10), an advertising medium that the consumer can keep.
• the surface or area available for messages with advertising content is much larger than that constituted by the surface or area of the packaging strip 14.
• the choice of materials available for the shirt 32 makes the prints much easier to implement by offering unlimited creative possibilities. It is also particularly advantageous to be able to use a standard or neutral product, that is to say not having any particular advertising message other than the brand of its manufacturer and its food composition, in association with a personalized packaging shirt 32. , especially according to an advertising campaign.
• the tongue 50 with its two opposite inner and outer faces also constitutes an additional advertising surface.
• the product is not perfectly parallelepipedal, for example curved such as a candy, a madeleine or a nougat, it is possible to provide a cut for example in the upper sheet, and / or lower and / or to conform the central portion of this curved form sheet complementary to the product.
• FIG. 6 schematically shows a product 10 packaged in a "flow-pack" type packaging.
• the product 10 is here, for example, a rectangular individual chocolate square or a flat rectangular biscuit such as a speculos (not visible in FIG. 6).
• the packaging of the product is constituted here, in known manner, by a strip or sheet 14 of flexible material, for example a transparent or opaque plastic sheet whose sealing is provided by thermoforming or heat sealing.
• the sealing technique of the packaging 10 is such that it results, in particular in the central part 72, in the formation of a covering 78 delimiting a slot in which, as schematically illustrated in FIG. 6, it is it is possible to introduce at least one free end section delimited by the vertical edge 55 of a retaining tongue 50 similar to that described above. This possibility is also illustrated schematically in the sectional view of FIG.
• the slot (under the cover 78) in which the retaining tab 50 is received is also closed at its two opposite vertical ends.
• Such a product 10 with its packaging "flow-pack” can be put in place and retained in a packaging jacket 32 of the type described and shown with reference to Figures 1 to 5, in the same way that a chocolate with its ring.
• the retaining tab 50 can extend "above” the upper face 18 of the product 10 "covering” the latter as illustrated in the figures or, as a variant not shown, extend “below” the lower face 16 of the product 10, that is to say that there is then the thickness of the paper of the ring or the "flow-pack” packaging 14 between the tongue 50 and the inner face 37 of the lower sheet 34.
• the retaining tongue 50 can extend over the entire height of the vertical front edge 40 and thus having the same height as the lower sheets 34 and upper 36, while the product 10 then protrudes upwards and downwards. downwards beyond the edges 33 and 35, the locking means in the closed position can also intervene at the right edges facing 56 and 44.
• the retaining tongue is not centered in the vertical edge 40 but can be shifted up or down.
• the packaging jacket is rigid and homogeneous which greatly facilitates the introduction and distribution of this type of products in the screw-type automatic distributors mentioned above.
• it can achieve two high 80 and low 82 (come from material by cutting and folding) which - in position of the product 10 inside the jacket 32 - extend opposite the upper end portions 74 and lower 76 "without thickness" of the sheet 14 of packaging which envelops the product made of chocolate 12.
• the dimensions of the different cutouts are such that the high side faces 86 and 88 of the bottom product 12 are received, virtually without play, between the edges facing low 90 and high 92 of the flaps 80 and 82 respectively.
• This design with two retaining flaps allows if necessary, especially if no slot is available or if the slot is not closed at its two opposite vertical ends to ensure the retention of the product.
• This design with two high and low shutters 80, 82 is also particularly suitable for the packaging of "non-flat" products, that is to say of generally convex shape such as candies, nougats, madeleines, etc..
• FIG. 10 Another embodiment modified for this purpose is illustrated in Figures 10 and following, here for the packaging of a small madeleine contained in a packaging type "flow-pack".
• the shirt 32 of conditioning is first of all modified in that its upper sheet 36 is divided or divided into two sections 36a and 36b which are separated by a vertical fold 94 so as to be able to conform the upper face 36 folded inverted V, as can be seen in Figure 12 and therefore the jacket 32 into a product of generally triangular section.
• the general polyhedral shape or prism triangular section of the jacket 32 can accommodate a product of various shapes and voluminous while retaining all the benefits inherent in the invention, including those relating to the maintenance or the retention of the product in the shirt 32.
• edges 90 and 92 of the cutouts defining the flaps 80 and 82 and the tab 50 are V-shaped opposite with the concave internal parts of the two capital letters V facing as can be seen in Figure 10.
• this allows to house the packaged product in its "flow-pack" between the two cuts 90 and 92 and therefore between the two flaps 80 and 82 easily and in such a way that the free ends 81 and 83 of the flaps 80 and 82 provide a "clamp" effect retaining even more the product.
• the length according to "L" of the two flaps 80 and 82 is preferably sufficiently large for when folding in a triangle and the closure of the jacket "force" the flaps to extend across, ie not parallel to the lower sheet 34.
• the retaining means constituted by the shutters 80 and 82 prevent a user from trying to extract the product vertically according to "V" by forcing him to open the folder, which is particularly important when the folder 32 comprises a message on the back.
• the locking tab 58 is received in a locking slot 64 formed in the fold 40 corresponding to the leading edge.
• the locking tab 58 extends longitudinally outwardly by a gripping lug 59 which facilitates the opening of the packaging for unfolding and access to the product it contains.
