Definitions
- the present invention relates, in a basic version, to a first flat packaging with quick mounting and locking (approximately 4 to 5 seconds), for cylindrical hamburger sandwiches (and in general for any rather compact food presented in cylindrical form and intended for be eaten in its packaging); the concept of this basic version makes it possible to decline a second packaging in two half shells, preformable manually with ultra-fast assembly-locking (1 to 2 seconds approximately) once preformed, and with limited stacking; and finally in a second version, a packaging also in two half shells, preformable industrially directly in the stacking position, then re-moldable in the filling position, can be mounted and locked manually in record time, specifically intended for professional use (during peak hours in fast food restaurants in particular).
- a cylindrical packaging case for round sandwiches consists of two half-shells surrounding the sandwich each on a half perimeter and connected to each other by a single hinge parallel to a generator of the cylinder. In the closed position, each shell comes into edge-to-edge contact with the other. During the packaging operation, the sandwich is placed vertically in the lower shell on which the upper shell folds down.
- This packaging is obtained by molding polyurethane foam and has several drawbacks: as the peripheral and lateral walls are perpendicular to each other and molded, the packaging is not stackable; the sandwich is too landlocked at the bottom of one shell, while the other shell collides the consumer's face, which is very uncomfortable, and all the more so in the final phase of consumption, since the radial detachment of the shell as well as the lateral detachments, designed to be able to access the last portion of the sandwich with the mouth , are awkward because they require a strong pull on the packaging which can tear suddenly, at the risk of dislocating the sandwich and dropping the food remains on the consumer or his neighbors. As far as we know, this packaging has never been used for these reasons.
- US Pat. No. 4,494,785 relates to a pre-cut and pre-pleated flexible paper towel intended to partially cover a cylindrical sandwich so as to hold it between the fingers without the latter coming into contact with the food.
- .It consists of a strip partially surrounding the periphery of the sandwich and two sets of parallel flaps two by two intended to be inserted between the fingers and respectively the top and bottom of the sandwich. This towel remains around the sandwich only if it is kept there by hand and does not effectively retain the sauce or fatty waste that escapes from the sandwich during its consumption nor does it ensure thermal insulation of the hot sandwich.
- the very old patent DE 336795 describes a rectangular parallelepiped box with square section with cross bottom closure obtained by diagonal folding of the four bottom fields; this box, accessible only from below, is mainly used for packaging powdered or granular products and has no specific characteristic for eating a round sandwich in its packaging, even if a box can serve many different uses.
- the cardboard sheet is divided into square areas equal along three longitudinal strips delimited by two parallel folding axes and five transverse strips delimited by four folding axes perpendicular to the previous ones.
- the box is placed on a horizontal table and redeployed in the plane of the table so that the ice remains on the central square area where it can be cut and served. that this box can receive a hamburger in a specific application, it is clear that it is not designed so that the hamburger is consumed in its packaging
- the round box disclosed in US Patent 2224504 is formed from a cylinder from a sheet of unspecified material comprising a central part and lateral extensions the length of which is precisely that of half the diameter of the product to be packaged .
- US patent 3031124 has a very complicated manual folding system and in no case capable of preforming in industrial series; if the aesthetic result is very attractive, this packaging in the form of The bag has no specific application, which was also desired here again by its inventor. In another consideration if this packaging had presented a specific interest for the consumption of a hamburger, we can think that it would have had time to know since 1959.
- Patent GB 945,399 describing in 1963 a process for wrapping different articles with a folded sheet, filmed or impregnated with polyethylene in particular, but also with aluminum, and above all the means of using the filming material to heat seal the folds organized to close the packaging by the thermoplastic affixing of a rigid label made of a compatible material, intended to externally present a trade mark.
- Figures 1 to 20 show the main originalities of the invention; in these figures, the symmetrical parts will always be represented by the same symbols (numbers or letters).
- Fig.l shows, seen from above, the central concept of one invention, voluntarily presented for the realization of a packaging of regular hexagonal section, on the one hand for the best possible reading of the figures, and on the other because it is one of the preferred presentations of the invention.
- the material of the thin sheet used could preferably be a thin cardboard, or micro-fluted, treated anti-grease in the thickness or at least on its internal face, completely recyclable, and of a weight per square meter between 180 and 250 grams.
- the packaging in this basic version is obtained by cutting an appropriate surface (best limiting falls) using a flat cutting tool usable under pressure. This surface resembles an elongated rectangle.
- the fold starters are obtained by a non-cutting tool secured to the cutting tool, and capable of printing on each of the faces of the cardboard -a deformation along different lines constituting folding edges.
- the folding edges shown in fig.l by solid lines (a) define groups of outgoing folds.
- the folding edges shown in fig.l by dotted lines (b) define re-entrant folds or support folds.
- Fig.2 shows fig.l after a first folding. It shows that two bands A and B are arranged in symmetry with respect to a band C to form the packaging. On this strip C, the width (e) of which corresponds to the thickness of the hamburger to be packaged, is shown horizontally an internal face (1) intended to receive the hamburger vertically. This face is the pivot face of the system; the enveloping faces (2), (3), (4), (5), (6) and (7) are of the same dimensions as the face (l) in this regular hexagonal presentation.
- the height (r) of the strips A and B (and therefore of the face (f) is preferably in this basic version equivalent to the radius of the hamburger to be packaged.
- the lateral and symmetrical faces (8) of a height (h) slightly greater than (r) consolidate and stabilize this grip by penetration of their protruding tab (o) between the face (f) and the hamburger, which constitutes the first stage of the packaging act for two-thirds (approximately) of the volume of the hamburger.
- the packaging of the remaining third is done by holding laterally between the thumb and forefinger of one hand the fixed structure obtained, delimited by the faces
- the packaging and locking operation took place without the face (1) having ever left its initial position on the horizontal plane where the packaging act is normally carried out, and the hamburger has remained completely immobile for 4 to 5 seconds of the duration of the operation, before being placed flat in its packaging and on its base to maintain its integrity.
- Figures 1 to 20 show a packaging structure of regular hexagonal section, the diameter of the hamburger being approximately that of the circle inscribed in one hexagon.
- Packaging structures of square or pentagonal section or of any other sections of regular polygons preferably are possible.
- the section packaging in regular hexagon proves to be optimal because the loss of volume in its six angles of 120 degrees is slight, the length of the cardboard useful for its realization is economical compared to the packaging of pentagonal and square section which it will be spoken later, and finally, like these, it has a number of side folds perfectly manageable for its shaping and good compactness.
- Fig.5 shows an adhesive patch (14) glued to strengthen the locking by folded in fold (10).
- Fig.6 shows an adhesive patch (14) glued for sole locking, the fold (9) being here completely removed when cutting the paper.
- the packaging s Organized in symmetry around the pivot face (1) implies that the lateral faces (f) in symmetry with respect to the face (l) are each delimited by two re-entrant folds of type (b) and two outgoing folds of type (a) designated by (p) in fig.l and fig.7.
- the two folds (p) can be used as female anchoring elements for an interesting form of locking.
- the face (4) and the faces (15) in symmetry with respect to (4) show cut anchors (16) having hinges (w) joining them to the faces (15).
- Fig.10 shows a wide tab (19) cut on the face (18) hinged on this face, and coming to hang in (20) behind the outer fold (t) of the face (8). This attachment is facilitated by a cutout (21) allowing the locking as shown in fig.ll.
- This tab locking is the quickest to implement, its robustness can be ensured by optimizing the tab (19). It is the preferred locking of the invention in this basic version in its various regular polygonal sections preferably. Similarly, for the locking also shown in fig.10 by the tab (23) cut on the face (22), hinged on this face and coming to hang in (24) behind the external fold (t) of the face (8), the attachment is facilitated by a specific cutout (25) allowing the locking as shown in fig.12.
- the tab (23) is better integrated into the aesthetics of the packaging but its installation, although easy, is less immediate than that of the tab (19) which keeps the preferably because of its better locking time.
- Fig 2 indicates on either side of the face (1), starting from the faces (f) two cutouts (12) symmetrical with respect to (f) and retained at the edge of the strips A and B by stopping points (13) .
- pivot (1) (vertically if the packaging is opened horizontally upwards, or horizontally if the packaging is lying on a plane and open to the horizontal), may fold over one another with overlap from face (4) to face (7), or vice versa.
- fig.14 Compared to fig.1,1a fig.14 is in total symmetry with respect to its central strip including the faces 1 to 7 and the strip perpendicular to it including the face (1) the faces (f) and the lips (ll) hinged on (f).
- the faces (26) have been truncated from the triangle (9) fig.l and no longer have any folding edges.
- the faces (27) have two outgoing fold edges (u) and two re-entrant fold edges forming right triangles (28) and (29).
- Fig.15 shows, laterally, how it is possible from the folds of Fig.14 to obtain the formation of two symmetrical half shells represented by the external visible faces (26, (27) and (30).
- outer (27) hides the two folds (28) and (29) attached to each other behind the face (27) inside the packaging so that a simple stapling in the area (31) can lock together from the inside the external faces (26), (27) and (30) to obtain a perfectly formed and resistant half-shell.
- This type of stapling can be carried out by a device known from the trade.
- the hamburger is quickly introduced against the pivot face (l) and it is locked while bringing the two half shells which are folded down, using light pressure with both hands. on the other to counteract the tension effect caused by the placement of the outer folds (mobile) on the inner folds (fixed) around the hamburger on either side of the faces (f).
- Fig.16 shows fig.15 after the flap of a half shell.
- the packages with preformed half shells, fig. 15 are stackable.
- the stacking has two major drawbacks: on the one hand it must be obtained under vertical pressure, since these packages to be superimposed horizontally on each other each have two symmetrical concavities constituted by the two half shells which can cause deformations of the packaging below, on the other hand and consequently, the quantity of stackable units is very small because in this doubly concave and almost vertical configuration saturation is quickly reached.
- Fig; 18 shows, seen from above, the assembly constituted by the two trays organized in symmetry of the face (1) itself contiguous to each of the faces (34) (extrapolated from the faces (f) of FIGS. 1 and 2 symmetrical with respect to it, each of these faces (34) having a lip (ll), also extrapolated from the figures of the previous boards, which can be moved inside or outside the packaging according to a creasing or a perforation ( m) horizontal located slightly above the base of the packaging; the erasure of the two lips (11) opposite towards the outside is provided to facilitate the complete consumption of the sandwich (S).
- the stacking is here made possible by the tensioning by bonding to the packaging of the small folds (a) which causes a stable elastic deformation, rounded outwards, of the corners of the half-shells along the folds between the face. (5) and the faces (33) adjacent to (5) and along the folds between the face (2) and the faces (33) adjacent to (2) (fig. 18).
- the optimal length of a fold (a) is that which allows the stable elastic deformation of the tray to be maintained on the two sides adjacent to its pivot fold with the face (1) without breaking the carton at the meeting points of the outer ends of the folds (a) with the outer edges of the tray.
- the packaging thus produced can pass, as explained below, from a stable stacking configuration to a stable configuration for filling the packaging with the sandwich, then to a stable closed configuration.
- the face (1) and the lateral faces (2) and (5) are approximately perpendicular to each other and one can only switch to the stable filling configuration if exerts pressure on each half shell by bringing (preferably at the same time and with both hands) the face (4) of the face (2) and the face (7) of the face (5) (fig. 18 bis) and by rotating them upwards each on its hinge fold with the face (1) until the tension of the fold (a) vanishes at the same time as the adjacent faces (5), (1) and ( 2) are positioned in the same plane, which plays the role of tilting plane of the packaging to change configuration.
- the small mobile folds (a) are the primary active element of the packaging.
- the sandwich is then enclosed and thermally insulated until consumption. During consumption, it is enough to separate the half-shells from one another and the sandwich is presented on its edge against the face (1). It is comfortably retained in the packaging by pressure of the fingers on either side on the sides of the lateral lips (11). The folding of the lips (11) towards the outside takes place without sudden movement when the mouth has to access the last portion. Until the end, the packaging prevented the flow of sauce, retained fatty waste and retained its initial aesthetic form.
- a second technical requirement of the packaging is that to avoid even better tearing the thin sheet of cardboard at the time of the packaging particularly at the level of the small folds (a) and (b) (especially in a manufacturing in very fast automation) very important that four small triangles (v), on either side of (34) between the folds of optimized reduced height (a) and (b), have the best possible resistance to tearing by the arrangement of spokes (g) and ( d) respectively at the outer angles of the folds of reduced size (a) and (b) with the third side of the triangle (v); these radii are intended to eliminate the incipient fractures always possible when the thin blanks, precut to the useful dimension provided, have sharp angles subjected to ent ent ent, tensions or pressures during the packaging.
- the tray itself is not the only possible cause of tearing of the packaging fig. 17 and 18 at the level of the small triangles (v): -in fact, the act of packaging itself of the sandwich (S) begins with the manual shaping of the packaging in the inversion operation which has been described above and whose notable effect is that the faces (5), (1) and (2) return in this order in the same plane in a stable configuration which is that of the filling of the hamburger.
- spokes (d) and (g) play an important role in the resistance to tearing at the instant of the hand turning of the face (1) causing the pseudo verticalization of the two half shells, face openings face to face, if by chance this reversal took place suddenly.
- the packaging still retains a sufficient spring effect when a fold (a) is torn on one tray or the other, or even if a fold (a) is torn on each of them.
- the polyethilene film-coated cardboard packaging has perfect tear resistance, both in packaging and in manual turning.
- the moist heat emitted in particular by a hot sandwich, inside a package as described in particular in FIGS. 15 and 19 has a natural tendency to soften the walls of said package and has weaken in particular its locking if it is not ensured in a sufficiently robust manner without hampering easy opening when eating the sandwich.
- the system chosen must necessarily not hinder the shaping of the trays, in particular if it is carried out in very rapid automation.
- Fig.17 shows in the extension of the center of the face (7) a tab (z), in the shape of a rounded arrowhead whose lugs (q) and (q ') located on a line parallel to the outside of ( 7), are distant by a value (n); the segment common to the tab and to the external face of (7), to it a value (L) slightly less than (n).
- a rectangular slot (y) of the order of 1 to 5 is produced at the center of the aforementioned fold. 2 millimeters in width and length (L) so that after the sandwich has been placed in the packaging, when it is locked, the tab attached to one of the two half shells can be snapped into the slot ( y) of the other half shell by a slight pressure taking into account that (L) is slightly larger than (n); (4) is then in perfect covering of (7)
- the opening of the packaging is carried out, at the useful moment very easily by a slight traction towards the outside to uncoupled the shells.
- the faces (3) comprising the lips (11) can be provided differently than they are in Figures (17) and (18).
- the constraints here are: first, the height of the face (34), lip (11) included, is greater than the value of the radius of the sandwich (S), so that once the packaging is closed on the sandwich, the face (34) does not leave the sandwich partially visible towards the center of the packaging, and on the contrary it protects it up to its diameter.
- the packaging is also the most perfectly closed laterally for the best temperature maintenance before consumption and this particularly for hot and humid sandwiches.
- Figs. 17, 18, 18bis, 19.20 (pl. 5) the sides of the faces (34) have been proposed in the extension of the folds (a) for a better reading of the figures; it is obvious that the opposite faces (34) can each be extended on either side towards the lateral faces (33) (Fig. 19) within the maximum limit of the two symmetrical portions (x), insofar as these equivalent portions added on both sides other of (34) are completely separated from the faces (33) as well as triangles (v) to allow the functioning of the bellows-springs between the folds (a) and (b).
- the hinge (m) of the lip (11) is ideally located between the two vertices (35) of the folds (a) on either side of the hinge (m) ; the segments (36) are cut to allow the wings (x) of (34) to enter the shells when the packaging is closed and above all to allow the spring bellows between (a) and (b) to function unhindered.
- Fig.21,22 and 23 show a packaging according to the last type, also capable of being manufactured industrially, but of regular pentagonal section. It includes seven wrapping faces for five sides of section, which implies that its locking principle brings into play four faces between them two by two, (the faces (6 '), (4'), (7 ') and (3 ')).
- the closure can obviously be done in the other direction.
- the locking is done naturally by the superposition of the angle (of 108 °) between the faces (3) and (4) on the angle (of 108 °) between the faces (6) and (7) at the end of the wrapping, while allowing easy unlocking.
- Figs. 24, 25 and 26 also show a packaging according to the last type, capable of being manufactured industrially, but of square section.
- This package includes five wrapping faces for four section faces which implies a lock of the same type as for the hexagonal section packaging after perfect covering of the external face (5 ") by the internal face (3") or vice versa fig.26.
- the stacking for this square packaging is obvious and does not imply resorting to the technique of inversion after packaging.
- the specific packaging must be practical since the sandwich must be eaten in its packaging to avoid spillage of sauce.
- the packaging itself must naturally invite this by its configuration alone, and it must somehow suggest to the consumer to exclude any different attitude. Consumer comfort certainly does not exist when the hamburger is served in a rectangular box which does not materialize any notable specificity as to the practical requirements specific to the consumption of the hamburger in its packaging. Consumer comfort does not exist either when the hamburger is presented in a package with two half-shells mounted on a simple hinge because the sandwich is wedged at the bottom of a half-shell with all the inconveniences already described above.
