Description

Folding box for packaging
The invention relates to a folding box for packaging, in particular for pastries designed from a single blank cut from a sheet of cardboard or plastic, or any other material whose characteristics allow it to be produced, and grooved in order to facilitate it. the folding.

 Current packaging has evolved in its impact resistance but has become less efficient in the visual aspect of marking, by design.

One of the objects of the invention is to design a folding box for packaging according to various innovations in order to maintain the effectiveness in impact resistance and to define different applications facilitating the marking.

The packaging is in the form of a single blank cut from a sheet of foldable material such as cardboard or plastic and grooved to facilitate folding, comprising a polygonal bottom (A.1) on which are articulated flaps (B.1,
B.2, B.3, B.4), composed of side walls (B.10, B.20, B.30,
B.40) adjacent to the bottom, provided with stiffening strips across their width (B.21, B.22, 3.41, B.42), the said side walls being extended by folding parts (C.1O,
C.20, C.30, C.40) forming the top of the box, and made up, in opposition of two tabs (C.10, C.30) or (C.30, C.30 bis) provided with a middle slit (C.ll, C.31) and two uprights (C.20, C.40) each terminated by a handle (D.20, D.40).

According to another characteristic of the invention, the flaps (B.1,
B.2, B.3, B.4) have, for at least two of them, a curved fold line (B.23, B.24, B.43, B.44) known as a hat intended to delimit the side wall (B.10, B.20, B.30, B.40) of the folding part (C.10, C.20, C.30, C.40). This fold line arises at the corner of the junction of the side wall and the foldable part to meet in the center of the side of the packaging (B.25, B.45) at a height greater than the natural line of folding. This curved fold line gives the top of the package the appearance of a dome ensuring the box when it is in its final form resistance to crushing.

According to another characteristic of the invention, the tongues that fold over the top of the box are
* either identical (C.30)
* either mismatched (C.30, C.30 bis) (C.10, C.30)
For (C.30, C.30 bis) the tongue (C.30 bis) is designed, for half, to recall the contours of the cut flat blank or marking label (E). For (C.10, C.30) the tongue (C.10) has the characteristic of covering the entire top of the box and gives the latter a hermetic quality, by the positioning of the flap (C.12), in the slot f C.32) of the tongue (C.30).

According to another characteristic of the invention, the definition of different applications facilitating the marking could be either advertising for the merchant, or indicative for the customer (party, birthday ...) or other.

This achievement took place
* by creating a tab (C.10, C.30 bis)
positioning on top of the packaging partially covering
(C.30 bis) or in full (C.10), inserting for
(C.30 bis) through a middle slit (C.31) around the base of the
handles (D.20, D.40) and for (C.10) by adding a flap
(C.12) in the slot (C.32) located on the flap opposite Il.30).

* by the design of a flat blank cutout or label (E)
(Ea) marking support, independent of the packaging, intended
to come insert
* or around the carrying handles (D.20, D.40) to
(E) in this case the design of the tongue (C.30 bis)
recalls the contours of the blank blank or label
(E)
* either by its sides (E.2, E.3) in the incisions (F.1,
F.2) made, on the side wall (s) of the box
(B.10, B.20, B.30, B.40).

According to another characteristic of the invention and considering that the current packaging is designed in three ways
- either with eight stiffening strips
- either with four stiffening strips
- either without
The present embodiment, with four stiffening strips (B-.21, B.22, D.41, D.42) has, by design, that is to say that the stiffening strips are integral with the adjacent walls by the ribs at their right angles (B.211, B.212, B.221,
B.222, B.411, B.412, B.421, B.422) and in that the folding is effected by the edge (B.210, B.220, B.410, B.420) starting at the right angle1 resistance to crushing and saving space in the corners of the packaging. The drawbacks of the above-mentioned designs are - for the first: the folding of the stiffening strips does not allow them to be placed in the angles of objects or other products of square or rectangular shape, resulting in a loss of space or deterioration in the case of fragile products, the edge created by the folding mobilizing the angular space of the packaging.

- for the second: the stiffening strips are designed adjoining only by only one of their sides giving only a slight resistance to crushing.

- for the third: apart from zero impact resistance, it cannot avoid the yawning of the flaps relative to each other.

According to another characteristic of the invention, the carrying handles (D.20, D.40) are cut outwards in a semi-oval shape (D.201, D.401) for easy sliding in the slots (C.11,
C.31) and internally (D.211, D.411) partly following the external lines in order to define a space suitable for total safety during wearing and that they have lateral recesses (D.22, D.23 , D.42, D.43) allowing their blocking in the slots (C.11, C.31).

According to the characteristics of the invention, the present design allows, by its flat blank, great ease in the placement of objects or other products. This advantage is also found in the unpacking as well as in the repacking, allowing by folding the box, the conservation of the products in the latter, avoiding the use of a different container.

The following description, made with reference to the accompanying drawings given by way of nonlimiting example, will make it possible to better understand the invention.

Figure 5 is a plan view of the cut blank, of a second embodiment according to the invention.

Figure 6 is a plan view of two examples of cut blanks or labels, independent of the package.

Figure 7 is a top view of the establishment of a cut blank or label blank on top of the package.

Figure 8 is a perspective view of the establishment of a flat blank cut on the side of the package.

Figure 9 is a plan view of the cutting mode of carrying handles.

According to the invention, in view of FIG. 1, the cut and grooved blank comprises a bottom (A.1.), Bordered by side flaps (B.1,
B.2, B.3, 3.4). Each component is formed by a wall (B.10, B.20,
B.30, B.40), and a folding part (C.10, C.20, C.30, C.40).

The folding parts are designed to be joined together, according to the following process - the uprights (C.20 and C.40) extended by the handles (D.20 and
D.40) are brought back towards the center of the packaging, the positioning being facilitated by the curved fold lines (B.23, B.24, B.43, B.44), said in hat.

- the tongue (C.30) is folded down in its turn and is inserted on the handles (D.20 and D.40) - the first fixing operation takes place thanks to the semi-oval design (D. 201, D.401) of the handles (D.20, D.40). These are fixed at the end of the slot (C.31) by their recesses (D.22, D.23, D.42, D.43) made wider than the folding parts (C.20, C.40) - then the tongue (C.10) cut laterally, in order to follow the fold lines (B.23, B.24, B.43, B.44) is positioned on the top of the box and adapts by first being inserted like the tongue (C.30)> then secondly, by the introduction of the flap (C.12) into the slot (C.32) giving total hermeticity to packaging.

Figure 2 shows the box in its folded form, revealing the positioning of the fold lines (B.23, B.24,
B.43, B.44) as well as the exterior (D.201, D.401) and interior (D.211, D.411) cutout of the carrying handles (D.20, D.40).

Figure 3 provides a better understanding of the system for fixing the stiffening strip (B.21). This has its right angle secured to the side walls (B.20, B.3 (>) giving better resistance to packaging. Folding is carried out thanks to an edge ru.210} originating in the angle right of its sides (B.211,
B.212) and extending in extension of the diagonal connecting the corresponding angle from the bottom to the diametrically opposed angle
Figure 45 which is a top view of the establishment of the stiffening strips (B.21, B.22, B.41, B.42) defines the positioning of these on the side walls (B.10 , B.30) making it possible to occupy the corners of the box with square or rectangular objects or products.

FIG. 5 proposes another embodiment of packaging, which differs from that proposed in FIG. 1 by replacing the tongue (C.10) with a tongue (C.30 bis), the design of which recalls the contours, half, cut blanks or labels (E) designed for marking, and by eliminating the slot (C.32).

Figure 6.A proposes the design of a cut flat blank or label (E) marking support, independent of the boot, making it possible to keep the objective of the marking on the packaging. This flat blank or label has external cutouts inscribed in the curves of the tongue (C.30.bis.) And a central slot (E.1.) Allowing its positioning around the carrying handles (D.20, D. 40).

Figure 6.B proposes another design of a flat blank or label (E Bis), allowing the marking. This is positioned on the side wall (B.20, B.40) thanks to its two lateral tabs (E.2, E.3) in the vertical incisions (F.1, F.2) made on the box .

Figure 7 is a view of the establishment of a cut blank or label blank (E) proposed in Figure 6.A on the top of the box.

Figure 8 is a perspective view of the establishment of a flat blank or label (E bis) proposed in Figure 6.B.

Figure 9 defines the design of the carrying handles (C.20, C.40). This is carried out first, by an external semi-oval cut (C.201> C.401) in order to make it easy to slide in the slots (C.ll, C.31), secondly, by a cut interior (D.211, D.411) wide enough to allow total grip, making carrying the box as secure as possible, and lastly, by cutting the handles at their base wider than the uprights (C.20 , C.40), in order to create recesses (D.22, D.23, D.42, D.43) blocking the flaps (B., B.4) during their refitting
