Definitions
- the invention relates to the field of "box-in-box" type packaging for the packaging of liquids, comprising on the one hand a cardboard packaging case and on the other hand a flexible pocket, made of flexible plastic material, having a valve, the flexible bag being intended to be received in the packaging case, only the valve of the flexible bag being accessible from outside the packaging case through an opening.
- Such packaging can be used in particular for packaging food liquids, in particular wine.
- the flexible pocket is an element separate from the case, which is engaged in the case after the latter has been shaped.
- the flexible bag can optionally be removed from the case, for example with a view to differentiated recycling between the cardboard case and the plastic material bag.
- the flexible pouch performs the functionalities linked to the fact of containing liquid, linked to its preservation, and to its distribution through the tap.
- the packaging case provides the functionalities related to the mechanical strength of the packaging as a whole, and the functionalities related to the information of the user by forming the support of any graphic presentation visible to the user.
- the case for such packaging is generally made of corrugated cardboard, in order to meet the main functionality of the case, which is to ensure the mechanical strength of the packaging as a whole.
- corrugated cardboard is a very suitable material for applications which require a certain mechanical strength of the packaging, which is the case in packaging of the "box-in-box" type.
- these packaging must be able to withstand the stresses linked to the weight of this liquid, while having no contribution from the liquid to the mechanical strength of the packaging as a whole.
- corrugated cardboard has drawbacks.
- corrugated cardboard has aesthetic characteristics inferior to those of solid cardboard, because, except in very special cases, it is not possible to obtain a perfectly flat and smooth external surface with corrugated cardboard.
- corrugated cardboard by nature has a thickness, due to the presence of the corrugated inner layer, and this thickness reveals, on the edge of the corrugated cardboard sheet, the internal structure comprising this corrugated inner layer.
- the corrugated cardboard cannot withstand stresses along the direction of its thickness, except to crush the internal corrugated layer, and to risk tearing the external layer, which somewhat limits the printing techniques likely to be implemented on its outer face, in any case capable of being implemented industrially at low cost.
- the object of the invention is to propose a packaging of the "cash-in addition" type which makes it possible to obtain a packaging having superior aesthetic properties, in particular by the presence of an external face having a controlled surface condition, and by the possibility of using a wide range of printing techniques.
- the invention relates to a packaging case obtained by folding a blank pre-cut from a sheet of cardboard and intended to accommodate a flexible pocket having a valve to form a "box-in-box" type packaging.
- the packaging case comprises an envelope which is tubular in a longitudinal direction and which has, in a transverse plane perpendicular to the longitudinal direction, a closed polygonal transverse contour around an interior space of the packaging case.
- packaging comprising at least four successive main panels traversing the closed polygonal transverse contour, two successive panels traversing the closed transverse contour being linked at a common longitudinal edge.
- the packaging case comprises an opening arranged in a main front panel to allow the tap of the flexible pocket to pass through.
- the packaging case comprises an upper closure at an upper longitudinal end of the tubular casing and a lower closure at a lower longitudinal end of the tubular casing.
- the packaging case is characterized in that:
- the packaging case is made of compact cardboard whose weight is greater than or equal to 300 g/m2, and less than or equal to 500 g/m2;
- the closed polygonal transverse contour has dimensions such that it is inscribed, in a transverse plane, in a rectangle whose width and depth are each included in the range going from 50 millimeters to 150 millimeters, and such that it delimits a cross section of the tubular casing in the range from 5000 square millimeters to 15000 square millimeters;
- the tubular casing has a longitudinal dimension in the range from 100 millimeters to 250 millimeters and defines an interior space whose volume is in the range from 1.2 liters to 3 liters;
- the upper closure of the packaging case comprises an upper closure flap which has an outline identical to the closed transverse outline of the tubular envelope, which is articulated by an attachment edge on a transverse edge of one of the panels main parts of the tubular casing, which comprises an insertion tab hinged at a free edge opposite the attachment edge, and which is provided with a reinforcement in thickness over at least part of its surface;
- the tubular casing comprises, at an upper transverse edge of one of the main panels, a locking tab for the upper closing flap;
- the lower closure of the packaging case comprises as many lower flaps as the number of main panels, each lower flap being connected to a lower transverse edge of one of the main panels of the tubular envelope, the lower flaps being folded down transversely to the longitudinal direction, being folded over with overlap and being glued together.
- the reinforcement in thickness of the upper closure flap comprises at least two folded panels which are each connected respectively to a distinct edge of the upper closure flap, distinct from the attachment edge and from the free edge of the upper closure flap, and which are folded down and glued against an internal face of the upper closure flap.
- the bottom closure of the packaging case has two bottom flaps with concave side edges and two bottom flaps with straight side edges.
- the locking tab is configured to form a tamper indicator.
- the tubular casing comprises exactly four main panels and has, in a transverse plane perpendicular to the longitudinal direction, a rectangular or square transverse contour.
- the invention also relates to a packaging of the "bag-in-box" type, comprising a packaging case and a flexible pouch having a tap, characterized in that the packaging case conforms to any previous claims.
- Figure 1 is a plan view of a flat cardboard blank suitable for the production of a packaging case in accordance with the teachings of the invention, illustrating the cutting lines, the pre-cut lines, and the grooves intended to facilitate the folding of the blank for the shaping of the case.
- Figure 2 shows a perspective view of the packaging case after shaping, the packaging case being empty and being shown with its upper closure still open, and of a flexible pocket adapted to be accommodated inside the case.
- Figure 3 shows a perspective view of the packaging case of Figure 2 after introduction, inside the case, of the flexible bag comprising a valve, after closing the case, and after positioning the ladle valve through the opening provided for this purpose.
- FIG 2 There is illustrated in Figure 2 a packaging case 10 for a packaging 12 of the "cash-in-box" type, this packaging case 10 being made of cardboard and being intended to accommodate a flexible pocket 14 having a tap 16.
- the flexible bag 14 is designed to contain a liquid, in particular a food liquid, and very particularly wine.
- the packaging case 12 is obtained by folding a blank 20 which is pre-cut from a sheet of cardboard.
- the packaging case 12 is obtained by folding a blank 20 pre-cut in one piece, from a single sheet of cardboard.
- the cardboard used for the pre-cut blank 20, and therefore for the packaging case 12 is a compact cardboard, also called flat cardboard, as opposed to a corrugated cardboard.
- a sheet of compact cardboard thus has a front face and a reverse face, and, in its thickness between the front face and the reverse face, this material has a substantially constant density, as opposed to a corrugated cardboard which has empty spaces between its face up and its face up.
- the use of a compact cardboard makes it possible to implement a wide variety of finishing and/or printing techniques for the packaging case, in particular for an external face thereof, including finishing and/or printing techniques requiring the application of significant pressure in the direction of the thickness of the support.
- the use of compact cardboard opens up the possibility of implementing printing techniques of the offset type, of the UV varnish type, of the hot foil type or of the screen printing type, directly on the compact cardboard, without having to pass by a decoration sheet added after printing on the cardboard.
- the use of compact cardboard opens up the possibility of implementing finishing techniques such as embossing, stamping, embossing and/or debossing which, in practice, cannot be implemented, at least not economically, with corrugated cardboard.
- compact cardboard has, at equivalent weight, less mechanical strength than corrugated cardboard.
- One of the challenges in designing the packaging case 12 according to the invention is therefore to design it in such a way that, despite the use of compact cardboard, the packaging case 12 has sufficient mechanical strength for its intended use, which is to contain a volume of liquid in a range from 0.7 to 0.9 times the internal volume of the case.
- the compact cardboard of the packaging case 12 may have a thickness in the range from 0.5 millimeters to 1.5 millimeters.
- the packaging case 12 comprises a tubular casing 22 in a longitudinal direction and having, in a transverse plane perpendicular to the longitudinal direction, a closed polygonal transverse contour around an interior space of the packing case.
- the tubular casing 22 comprises at least four successive main panels 24, 26, 28, 30 traversing the closed polygonal transverse contour. Two successive main panels traversing the closed transverse contour are linked at a common longitudinal edge, the common longitudinal edge corresponding to a folding line of the cardboard sheet.
- the four successive main panels 24, 26, 28, 30 are therefore juxtaposed to one another. in a transverse direction.
- the number of main panels of the tubular casing 22 is equal to the number of sides of the polygonal transverse outline of the tubular casing 22. In the example illustrated, the number of main panels of the tubular casing is equal to four.
- the polygonal transverse contour of the tubular casing is therefore a quadrilateral, preferably a rectangle or a square. However, the number of main panels of the tubular casing 22 could be greater than four.
- FIG. 1 there is shown in continuous thick lines the free or cut edges of the blank 12, including the outer contour.
- Predefined fold lines marked in the material of the blank, at the level of which the blank is not cut or in any case not entirely cut, have been represented in phantom.
- the realization of the fold lines can involve one or more techniques, among which we can cite for example:
- the blank 10 therefore comprises, in the example shown, four main panels 24, 26, 28, 30 which are juxtaposed and hinged successively to each other around three fold lines 31, 32, 33 longitudinal parallels.
- a first fold line 31 connects, by delimiting them, a distal end main panel, which will here be arbitrarily qualified as front main panel 24, and a distal intermediate main panel, which will be arbitrarily qualified here as first side panel 26.
- a second fold line 32 connects the first side panel 26 to a proximal intermediate main panel, which will here be arbitrarily referred to as the rear main panel 28, and which is connected along a fold line 33 to a main proximal end, which will be arbitrarily qualified here as the second side panel 30.
- the fold lines 31, 32, 33 therefore define, in the flat blank 20, the longitudinal sides of the corresponding main panels.
- the main front panel 24 within the meaning of the invention could be any of the main panels 24, 26, 28, 30 successively juxtaposed in the blank 20.
- the main front panel 24 also comprises a longitudinal side 29 by which it is connected to an assembly flap 23, the longitudinal side 29 corresponding to a fold line between the main front panel 24 and the assembly flap 23.
- the assembly flap 23 Transversely opposite the longitudinal side 29, the assembly flap 23 has a longitudinal free edge 21, which is a free edge of the blank 20, belonging to the outer contour of the blank 20.
- the second side panel 30 comprises, transversely opposite the longitudinal side 33, a longitudinal side 34 which, in this embodiment, is a free edge of the blank 10, belonging to the outer contour of the blank 20.
- Each of the main panels 24, 26, 28, 30 has upper opposite transverse sides 24s, 26s, 28s, 30s and lower 24i, 26i, 28i,
- the main panels all have the same dimension in the longitudinal direction so that, in the flat blank 20, the upper and lower transverse edges of the four main panels are respectively aligned along an upper transverse line and along a lower transverse line.
- the four main panels 24, 26, 28, 30 are intended to form, after folding at 90° around each of the fold lines 31, 32, 33, which then each become a common longitudinal edge between two successive main panels, a tubular envelope 22, closed on itself, in which the main panels define the closed polygonal contour around an interior space of the case 10.
- the assembly flap 23 can itself also be folded at 90° around the fold line 29 so as to be able to be brought into abutment, plane against plane, against the second side panel 30.
- An assembly of the assembly flap 23 on the second side panel 30, for example by gluing, allows to fix the three-dimensional geometry of the packaging case.
- the fact that the envelope defines a closed contour does not preclude the main panels that make it up from possibly having windows or openings.
- the packaging has a dimension in the longitudinal direction which is greater than its dimensions in the other two directions, preferably at least twice as large.
- the closed polygonal transverse contour delimited by the tubular casing 22 has dimensions such that it is inscribed, in a transverse plane, in a rectangle whose width and depth are each included in the range from 50 millimeters to 150 millimeters, and such that it delimits a cross section of the tubular casing in the range from 5000 square millimeters to 15000 square millimeters.
- the two transverse dimensions of the rectangle or the square which can for example be called width and depth, are therefore each included in the range ranging from 50 millimeters to 150 millimeters.
- the closed polygonal transverse contour of the tubular casing 22 is a square contour with sides of 100 millimeters, which therefore delimit a cross section of the tubular casing equal to 10,000 square millimeters.
- the tubular casing 22 has a longitudinal dimension in the range from 100 millimeters to 250 millimeters and defines an interior space of between 1.2 liters and 3 liters. This volume is particularly suitable for food liquids such as wine.
- the dimensions of the tubular casing 22 are chosen in consideration of a part of the useful volume sought for the packaging 12, that is to say the volume of liquid likely to be contained in the packaging 12 , but also in consideration of the lower mechanical strength of the packaging case 10, which is due to the choice of using compact cardboard of intermediate weight for the production of the tubular casing 22 thereof. It is also noted that the transverse dimensions of the packaging case 10 are such that they allow gripping with one hand of the packaging 12.
- the packaging case 10 includes an opening 40 arranged in the main front panel 24 to allow, during use by an end user, the passage of the valve 16 of the flexible bag 14.
- This opening 40 is intended to be implemented after the introduction of the flexible pouch 14 into the case 12.
- the opening 40 is arranged under the shape of a pre-cut when the blank 20 is produced.
- the pre-cut for the opening 40 has a lower portion 40.1, which here is of circular geometry and which has a pre-cut over the entire length of its circular contour so that, when using the packaging, this lower portion 40.1 can be entirely removed for the passage of the tap 16.
- the pre-cut for the opening 40 has an upper portion 40.2 which has an upper edge t ransversal 40.21 in the form of a fold line, not pre-cut, and two side edges 40.22 which each connect one end of the upper transverse edge 40.21 with the pre-cut contour of the lower portion 40.1.
- the two side edges 40.22 are pre-cut, for example analogously to the pre-cut contour of the lower portion 40.1.
- the upper portion 40.2 forms, in the main front panel 24, a hinged flap around its upper transverse edge 40.21 which allows on the one hand the installation and the passage of the valve 16 of the flexible pocket 14 through of opening 40, and on the other hand, after use of the packaging 12, the easy removal of the flexible pouch 14 from the packaging case 10.
- the flap formed by the upper portion 40.2 extends substantially in the plane of the main panel front 24 and allows, by its lower edge, to wedge the tap 16 vertically.
- the opening 40 is arranged near a lower longitudinal end of the tubular casing 22, therefore in the lower part of the front panel 24.
- the packaging case 10 comprises an upper closure 50 at an upper longitudinal end of the tubular casing 22 and a lower closure 60 at a lower longitudinal end of the tubular casing 22.
- the lower closure 60 of the packaging case 10 forms a glued bottom which is particularly advantageous for imparting rigidity to the packaging case 10 when the latter is shaped.
- the lower closure 60 of the packaging case 12 comprises as many lower flaps 24ri, 26ri, 28ri, 30ri as the number of main panels 24, 26, 28, 30, i.e., in the illustrated example, four lower flaps 24ri, 26ri, 28ri, 30ri.
- each lower flap 24ri, 26ri, 28ri, 30ri is connected to a lower transverse edge 24i, 26i, 28i, 30i of one of the main panels 24, 26, 28, 30 of the tubular casing 22.
- the shaping of the packaging case 10 the lower flaps 24ri, 26ri, 28ri, 30ri are folded transversely, at right angles to the longitudinal direction, towards the inside of the space delimited by the envelope tubular 22.
- the lower flaps 24ri, 26ri, 28ri, 30ri are folded over with overlap and they are glued together to ensure locking of the lower closure 60 of the packaging case 12.
- the lower closure 60 of the packaging case 10 comprises two lower flaps 26ri, 30ri with concave side edges and two lower flaps with straight side edges 24ri, 28ri.
- the side edges of each of the lower flaps are edges which extend from the lower transverse edge of the corresponding main panel, in a general direction substantially perpendicular to this lower transverse edge. Both edges sides of each of the lower flaps extend to a free transverse edge of the corresponding lower flap.
- the two lower flaps with concave side edges 26ri, 30ri are carried by two main panels 26, 30 which are not consecutive in the blank 10, and which are therefore opposed to each other on either side. another of the interior space delimited by the tubular casing 22 when the packaging case 10 is shaped.
- the two lower flaps with concave side edges 26ri, 30ri are intended to be folded down first.
- the two lower flaps with concave side edges 26ri, 30ri advantageously have, at or near their free transverse edge, a transverse dimension substantially equal to that of the main panel 26, 30 by which they are carried.
- the two lower flaps with straight side edges 24ri, 28ri are carried by the other two main panels 24, 28, which are also not consecutive in the blank 10, and which are therefore also opposed to each other. the other on either side of the interior space delimited by the tubular casing 22 when the packaging case 10 is shaped.
- the two lower flaps with straight side edges 24ri, 28ri are folded down second, so after the two lower flaps with concave side edges 26ri, 30ri.
- 26ri, 28ri, 30ri have a dimension such that, once folded down, two flaps carried by opposite panels do not overlap, but on the other hand each lower flap with straight side edges 24ri, 28ri partly covers each of the two lower flaps with concave side edges 26ri, 30ri, and each lower flap with straight side edges 24ri, 28ri is glued with each of the two lower flaps with concave side edges 26ri, 30ri. Through this bonding, the closure lower part 60 gives good rigidity to the lower part of the tubular casing 22.
- the lower closure 60 of the packaging case 10, glued could be made in the form of an automatic bottom comprising lower flaps which overlap, which are glued together and which, moreover , are assembled together before the final shaping of the packaging case 10. In such a construction, the lower bottom of the packaging unfolds automatically during the shaping of the packaging. packaging case 10.
- a person skilled in the art knows many ways of making an automatic bottom with glued flaps.
- the upper closure 50 of the packaging case 12 comprises an upper closure flap 52 which has an outline identical to the closed transverse outline of the tubular casing 22.
- This flap of upper closure 52 is articulated by an attachment edge on a transverse edge of one of the main panels of the tubular casing.
- the upper closure flap 52 is linked to the rear main panel 28 at the level of the upper transverse edge 28s thereof, which therefore also forms the attachment edge of the upper closure flap 52.
- the upper transverse edge 28s of the rear panel 28 therefore takes the form of a fold line.
- the upper closure flap 52 includes an insertion tab 54 which is hinged at a free edge 56 of the upper closure flap 52, this free edge 56 being opposite the attachment edge 28s of the closure flap top 52.
- the insert tab 54 can be folded 90° around the free edge 56, and the top closure flap 52 can be folded down 90° to adopt a horizontal transverse orientation in which the insertion tab 54 is inserted into the interior space delimited by the tubular casing 22.
- the insertion tab 54 is thus found, in the configuration of closure of the upper closure flap 52, engaged in the interior space facing the internal face of the main front panel 24.
- the transverse width of the insertion tab 54 corresponds to that of the main front panel 24 in such so that the insertion tab 54 is wedged transversely between the two main side panels 26, 28.
- the assembly formed by the upper closure flap 52 and the insertion tab 54 stiffens the upper longitudinal end of the tubular casing 22, in particular by blocking deformations in diagonal transverse directions with respect to the cross section of the tubular casing 22.
- the upper closing flap 52 is provided with a reinforcement in thickness over at least part of its surface.
- this reinforcement in thickness is made in the form of an additional thickness of cardboard.
- the reinforcement in thickness could be made in the form of a separate piece of cardboard from the blank 20, and attached to the lower closing flap 52, preferably on the internal face of the latter which faces the interior space of the packaging case 10 when the upper closure flap 52 is in the closed configuration.
- this reinforcement in thickness is made in the form of at least one flap forming part of the same blank 20 in a single piece as the rest of the packaging case 10, such a flap being articulated around one of the edges of the upper closing flap 52.
- the thickness reinforcement of the upper closure flap 50 comprises at least two folded panels 70 which are respectively each connected to a separate edge 58 of the upper closure flap 52, these two separate edges 58 also being separate from the attachment edge 28s and from the free edge 56 of the upper closure flap 52.
- the two folded panels 70 are folded down and glued against an internal face of the upper closure 52, which faces the interior space of the packaging study when the upper closure flap 52 is in the closed configuration.
- the tubular casing 22 has a closed polygonal transverse contour with four sides, so that the upper closure flap 52 also has four sides, therefore two opposite side edges 58, which each respectively join the attachment edge 28s to the free edge 56 of the shutter upper closure 52, and which, in the closed configuration of the upper closure flap 52, are each aligned respectively with one of the two main side panels 26, 30 of the tubular casing 22.
- the reinforcement in thickness of the upper closure flap comprises two folded panels 70 which are each connected respectively to one of the opposite side edges 58 of the upper closure flap 52, and which are folded down and glued against an internal face of the upper closure flap 52.
- the two folded panels 70 do not overlap. However, provision could be made for the two folded panels 70 to overlap at least partially, in which case the upper closing flap 52 would locally present a triple thickness of cardboard, or even for them to overlap completely, in which case the upper closing flap 52 would present a triple thickness of cardboard over its entire surface.
- the thickness reinforcement prevents the packaging case from deforming in diagonal transverse directions.
- the upper closure flap 52 thus reinforced will better resist forces perpendicular to its extension plane, and therefore longitudinal forces. Such efforts can result from the presence of the flexible pocket 14 when it is accommodated inside the packaging study and when it is full. It is therefore understood that the upper closure flap 52 is not glued in its closure configuration, and that it is therefore possible to reopen it, like a lid, by tilting around the edge of attaches 28s.
- Such an ability to open the upper closure flap 52 is favorable because it allows, after the packaging 10 has been used, for example when the flexible pouch is empty, to easily open the packaging case 12 to remove easily the flexible bag 14, for example for differentiated recycling between the packaging case 10 of cardboard and the flexible bag 14 of plastic material.
- the tubular casing 22 comprises, at an upper transverse edge of a of the main panels, a locking tab 80 of the upper closing flap 52.
- this locking tab 80 is arranged at the level of an upper transverse edge of one of the main panels which is opposite to that of the main panels to which is attached the upper closure flap 52.
- the locking tab 80 is thus advantageously arranged at the level of the upper transverse edge 24s of the main front panel 24 of the tubular casing 22.
- lock 80 has a projection which, when the upper closure flap 52 is in the closed configuration, is intended to be engaged in a slot 82 arranged in the center of the free edge 56 of the upper closing flap 52, between the upper closing flap 52 and the insertion tab 54.
- the locking tab 80 may be configured to form a tamper indicator, for example by having the shape of a harpoon.
- a first closing operation of the upper closure 50 of the packaging case 10 after the flexible pouch 14, filled with liquid, has been inserted into the interior space delimited by the tubular envelope 22, will be able to lock the upper closure flap 52 in the closed configuration thanks to the locking tab 80, and any attempt to open it will be visible, for example due to an alteration or even a tearing of the locking tab 80.
- This makes it immediately visible that an unplanned intervention has been made on the packaging, and that the flexible bag 14 or its content may have been altered.
- the tamper evidence formed by the locking tab 82 seems intact, this reinforces the user's confidence in the integrity of the packaging 10 and therefore of the liquid contained in the flexible pouch 14.
- the packaging case 10 also comprises, at each of the upper transverse edges 26s, 30s of the two main side panels 26, 30, a dust flap 90 which is intended to be folded transversely inwards, to limit the intrusion of dust into the interior space delimited by the tubular casing 22.
- a dust flap 90 which is intended to be folded transversely inwards, to limit the intrusion of dust into the interior space delimited by the tubular casing 22.
- the presence of these anti-dust flaps 90 which are linked to the corresponding main side panel over the entire transverse dimension of the panel, also makes it possible to prevent the edge of the cardboard sheet from being visible at the level of the corresponding upper transverse edge 26s, 30s.
- the packaging 12 according to the invention and in particular the packaging case 10, therefore has a set of characteristics which, combined together, make this packaging 12 particularly suitable for packaging liquids such as wine, for which it is generally sought, for relatively low useful volumes, for example between 1 liter and 2.25 liters of liquid, both sufficient mechanical strength in use, and a possibility of quality finish and presentation, specific to convey a positive brand image associated with this product, while being economical to produce both by the low cost of the raw material used for the packaging case 10 and by the ease of implementation on pre-existing industrial lines cutting, folding and shaping of compact cardboard packaging.
