Description

Title of the invention: Palletizable packaging for storing bottles at an angle technical field

[0001] The invention falls within the field of storing bottles in palletizable packaging.

[0002] The invention relates more particularly to the storage of bottles at an angle in a parallelepiped-shaped carton in order to save space and optimize palletizing operations.

[0003] PRIOR ART AND DISADVANTAGES OF PRIOR ART

[0004] There are systems for holding bottles, particularly glass bottles, at an angle, which ensure that the bottles are held at an angle in a parallelepiped-shaped cardboard box. These include the systems described in publications FR3104145 and FR3016348.

[0005] However, these systems involve the design of complex packing pieces to manufacture and requiring a specific positioning operation by the operator, lengthening the duration of the packaging operations.

[0006] Although the system described in publication EP2456678 is simpler in its design, the secure retention of the bottles in position in the packaging, and in particular their longitudinal retention, is not sufficiently ensured.

[0007] OBJECTIVE OF THE INVENTION

[0008] The invention therefore aims to provide an optimized palletizable packaging for storing bottles at an angle which is simple in design, requires minimal assembly operations and whose manufacturing process is inexpensive.

DETAILED DESCRIPTION OF THE INVENTION

[0014] It is first specified that in the figures, the same references designate the same elements regardless of the figure in which they appear and regardless of the form of representation of these elements. Similarly, if elements are not specifically referenced in one of the figures, their references can easily be found by referring to another figure.

[0015] It is also specified that the figures essentially represent one embodiment of the object of the invention but that there may be other embodiments which meet the definition of the invention.

[0016] The invention relates to a palletizable packaging for storing bottles at an angle which is made in a single side.

[0017] By way of non-limiting agreement, the invention is described through three embodiments. The first two embodiments of figures 1 to 6 and 7 to 13 respectively relate to a configuration in which the packaging comprises a single layer of bottles, and the third embodiment of figures 14 to 21 relates to a configuration in which the packaging comprises a lower layer and an upper layer of bottles, while still being made from a single side.

[0018] With reference to Figures 1 to 6, the packaging of the first embodiment of the invention comprises a rectangular bottom wall 2a ([Fig.2]) made of four panels 2a1a, 2a2, 2a3, 2a4 which, by their assembly and as known to those skilled in the art, define said bottom wall 2a. The bottom wall 2a defines, according to its length, the longitudinal axis XX' of the packaging la.

[0019] The packaging la further comprises a perimeter wall 3a having two parallel longitudinal walls 4a, each connected to the bottom wall 2a by a fold line 5a, and two parallel side walls 6a, each connected to the bottom wall 2a by a fold line 7a. The bottom wall 2a and the perimeter wall 3a are designed to accommodate a layer of six bottles 8 ([Fig. 3]) oriented head-to-tail by defining two rows 9a; 10a of bottles, the axes XI, XI' of the bottles 8 being parallel to each other, arranged in a plane parallel to the bottom wall 2a, and inclined with respect to the longitudinal axis XX' of the packaging la. This defines their angled positioning within the packaging.

[0020] According to the invention, the packaging la comprises two covering walls 1 la,12a, each of them being intended to at least partially cover a row of bottles 9a,10a. Each cover wall lia,12a has a main body 13a, 14a connected to a free edge for retaining bottles 15a, 16a which will be described in more detail later.

[0021] Each cover wall 1la,12a is connected by a fold line 17a, 18a to the upper edge of an associated side wall 6a.

[0022] In the position of use (figures 4 and 5), each cover wall 1 la, 12a extends from the side wall 6a to which it is attached, to the free edge of the bottle retainers 15a, 16a which is connected to the main body 13a, 14a of the associated cover wall 1 la, 12a by a transverse fold line 19a, 20a.

[0023] Each free edge of the bottle retainers 15a, 16a includes means for holding the bottles 8 in position within the packaging la. More specifically, each free edge of the bottle retainers 15a, 16a includes three longitudinal bottle retainers 21a, 22a extending longitudinally from the main body 13a, 14a of the associated cover wall 1 la, 12a. As will be described later with reference to the packaging assembly operations, each longitudinal bottle retainer 21a, 22a is designed to bear against the upper end of a bottle in the opposite row, holding that bottle in place relative to the longitudinal axis XX' of the packaging la.

[0024] In addition, two longitudinal retaining tabs of the bottles 21a, 22a have two opposing lateral shims 27a, 28a, each connected to the longitudinal retaining tab of the bottles 21a, 22a by a longitudinal fold line 29a, 30a, and which are intended to bear against the shoulder and ring of two adjacent bottles 8 arranged in two opposing rows of bottles 9a, 9b, respectively. The third longitudinal retaining tab of the bottles 21a, 22a is located in the extension of a longitudinal edge of the main body 13a, 14a of the associated cover wall 11a, 12a and has only one opposing shim 27a, 28a directed on the opposite side from said longitudinal edge of the main body 13a, 14a.

[0025] As illustrated in [Fig. 4], the opposing lateral shims 27a, 28a extend, in the operating position when the associated cover wall 1la, 12a is in the overlapping position, longitudinally between the shoulder of a bottle 8 of the bottle row 9a, 10a covered by said cover wall 1la, 12a, and the ring of a bottle 8 of the opposite row 9a, 10a, the upper end of this ring being held in place relative to the longitudinal axis XX' by the longitudinal retaining tab 2la, 22a to which two opposing lateral shims 27a, 28a are connected. The opposing lateral shims 27a, 28a and the longitudinal retaining tabs of the bottles 21a, 22a thus allow to hold in position each upper end of a bottle 8 along the longitudinal axis XX' of the packaging 1a, but also relative to the two adjacent bottles 8 of the opposite row 9a, 10a in contact with this first bottle. The upper ends and shoulders of the bottles 8 are thus held in a secure position relative to each other.

[0026] According to the invention, longitudinal retaining tabs for the bottles 21a, 22a are preferred. By holding the ends of the bottles 8 in place relative to the longitudinal axis XX', they also prevent excessive contact between the ends of each bottle 8 and the shoulders of the bottles in the opposite row. However, the presence of opposing lateral securing tabs 27a, 28a ensures that there is absolutely no direct contact between the ends of each bottle 8 in a row 9a, 10a and the shoulders of the bottles in the opposite row 9a, 10a.

[0027] The packaging of the invention further comprises lateral retaining tabs for the body of two adjacent bottles 23a,24a. Each lateral retaining tab for the body of two adjacent bottles 23a,24a extends from the main body 13a,14a of a cover wall 1la,12a by being connected to this main body 13a, 14a by a fold line inclined 25a, 26a with respect to the longitudinal axis X,X' of the packaging and parallel to the axis XI,XL of the bottles ([Fig. 1]).

[0028] Each lateral retaining tab 23a, 24a is pivotally mounted about the inclined fold line 25a, 26a from an inactive position in which the tab 23a, 24a fits into a slot in the main body 13a, 14a of the cover wall 11a, 12a, to its active retaining position. More particularly, the same slot in the main body 13a, 14a of a cover wall 11a, 12a has two adjacent lateral retaining tabs 23a, 24a which are pivotally mounted about two fold lines 25a, 26a forming two opposite edges of said slot. Thus, the two adjacent lateral retaining tabs 23a, 24a of the same slot pivot in opposite directions until they reach their respective positions for laterally retaining the body of two adjacent bottles 8.

[0029] As can be seen in Figures 1 and 2, the opening receiving two lateral retaining tabs for the body of two adjacent bottles 23a, 24a is larger than the size of the two tabs 23a, 24a. This part of the opening, which does not receive the two lateral retaining tabs for the body of two adjacent bottles 23a, 24a, has an aesthetic appearance which, as illustrated in [Fig. 5], provides a pleasing visualization of a portion of the bottle 8 positioned between the two lateral retaining tabs within the same opening.

[0030] When, as illustrated in Figures 1 to 6, each row of bottles 8 comprises three bottles 8, and the two cover walls 1a, 12a each comprise a unique light equipped with two lateral retaining tabs for the body of two adjacent bottles which are arranged, in the position of use, on either side of the central bottle of a row, thus avoiding direct contact between the body of the three adjacent bottles.

[0031] Considering together the longitudinal retaining tabs of the bottles 21a, 22a, the opposing lateral securing tabs 27a, 28a and the lateral retaining tabs of the body of two adjacent bottles 23a, 24a, the bottles of the packaging of the invention are thus totally held in the diagonal position securely both at the level of the body of the bottles and at their upper part (upper end and ring / neck / shoulder) but also as much laterally (opposite lateral securing tabs 27a, 28a and lateral retaining tabs of the body of two adjacent bottles 23a, 24a) as longitudinally (the longitudinal retaining tabs of the bottles 21a, 22a).

[0032] Notwithstanding, the invention relates primarily to the presence of means for holding the bottles in position, which are provided at the level of the foldable free edge of the cover walls, and more preferably to the presence of longitudinal bottle retaining tabs 21a, 22a which, by holding the ends of the bottles 8 in place relative to the longitudinal axis XX', also ensure a certain lateral retention of the bottles. This retention is, of course, improved by the presence of opposing lateral wedge tabs 27a, 28a and lateral retaining tabs for the body of two adjacent bottles 23a, 24a.

[0033] With reference to Figures 5 and 6, the packaging la comprises two upper closing walls 33a which, in the closed position, completely cover the bottle tier 8. Each closing wall 33a is connected by a longitudinal fold line 34a to a longitudinal wall 4a of the perimeter wall 3a. This closing configuration is well known to those skilled in the art.

[0034] The assembly operations for the packaging are described below.

[0035] Starting from the side shown in [Fig. 1], the four panels 2a1, 2a2, 2a3, 2a4 are assembled to form the base 2a, which simultaneously leads to the construction of the perimeter wall 3a around the base 2a. The assembly is held together by means known to those skilled in the art, for example a tab 38 ([Fig. 1]) which fits into a corresponding opening not shown in the figures and provided in the opposite longitudinal wall 4a.

[0036] Once the base 2a and the perimeter wall 3a are mounted, the 6 bottles are installed on the base ([Fig.3]) oriented head-to-tail and defining two rows 9a, 10a of bottles, the axes X1,X1' of the bottles 8 being parallel to each other, arranged in a plane parallel to the base wall 2a and inclined with respect to the longitudinal axis XX' of the packaging la.

[0037] With reference to figures 3 and 4, prior to the installation of the cover walls 1la,12a, the lateral retaining tabs of the body of two adjacent bottles 23a,24a are brought into pivoting with respect to the associated fold lines 25a,26a substantially perpendicular to the main body 13a, 14a of the cover walls lia,12a.

[0038] With reference to [Fig.4], a first cover wall 12a is pivoted around the fold line 18a until it rests on the corresponding row of bottles 9a. Simultaneously, the lateral retaining tabs of the body of two adjacent bottles 23a,24a are positioned between two adjacent bottle bodies 8.

[0039] At the same time, the free edge of the bottle retainers 16a is pivoted relative to the folding line 20a into its active holding position substantially perpendicular to the bottom wall 2a. During this pivoting, the longitudinal retaining tabs of the bottles 22a are positioned against the ends of the bottles 8 of the opposite row 10a.

[0040] As regards the shims 28a, prior to pivoting the free edge of the bottle retainers 16a, they can be pivoted around the associated folding line 30a to ensure their positioning between the shoulder and the ring of two adjacent bottles 8 of two rows of opposite bottles.

[0041] However, according to the invention, the insulating tabs 27a, 28a are shaped so that, without pivoting around their associated folding line 29a, 30a prior to pivoting the free edge of the bottle retainers 15a, 16a, they can position themselves between the shoulder and the ring of two adjacent bottles 8 in two opposing rows of bottles. To achieve this, and with reference to Figures 1 and 2, the upper edge of each insulating tab 27a, 28a joins the lateral edge of the associated longitudinal retainer tab 21a, 22a, forming, with this lateral edge of the associated longitudinal retainer tab 21a, 22a, a continuous curved edge 45a, 46a, devoid of a break angle.Thus, the opposing lateral wedge tabs 27a,28a position themselves between the shoulder and the ring of two adjacent bottles 8 of two rows of opposing bottles without performing any additional operation other than bringing the free edge of bottle retention 15a,16a into pivoting relative to the folding line 19a, 20a into its active holding position substantially perpendicular to the bottom wall 2a. .

[0042] The same procedure is followed for the second covering wall lia which is brought into overlap on the second row of bottles 10a.

[0043] With reference to [Fig.6], the two upper closing walls 33a are finally brought to pivot around the associated folding lines 34a and means known to the person skilled in the art ensure the closure of the package.

[0044] With reference to figures 7 to 13, the packaging of the second embodiment of the invention has a large number of elements in common with the first embodiment.These common elements will not be described in detail below; the description relating to the first embodiment applies with regard to the four panels 2b, 2b2, 2b3, 2b4, the bottom wall 2b, the perimeter wall 3b, the parallel longitudinal walls 4b, the fold lines 5b, 7b, the rows 9b, 10b of bottles, the two cover walls 11b, 12b, the main bodies 13b, 14b and the free edges for retaining the bottles 15b, 16b of the cover walls 11b, 12b, the associated fold lines 17b, 18b, 19b, 20b, the longitudinal bottle retaining tabs 21b, 22b, the associated fold lines 29b, 30b and their continuous curved edge 45b, 46b, the opposing lateral securing tabs 27b, 28b, the lateral retaining tabs of the body of two adjacent bottles 23b, 24b and the associated inclined folding lines 25b, 26b. .

[0045] With reference to figures 7, 8 and 9, what characterizes the second embodiment is the presence of a double bottom wall 35b which is connected by a longitudinal fold line 36b to a connecting wall 31b itself connected by a longitudinal fold line 32b to a longitudinal wall 4b of the perimeter wall 3b.

[0046] As illustrated in [Fig. 9], in the operating position, said connecting wall 31b is positioned against the inner face of the associated longitudinal wall 4b by folding around the two longitudinal fold lines 32b, 36b. Since the height of the connecting wall 31b is substantially equal to the height of the longitudinal wall 4b, the double bottom wall 35b then rests against the bottom wall 2b.

[0047] The double bottom wall 35b has a dimension substantially equal to that of the bottom wall 2b and also has two rows of oblong recesses 37b inclined with respect to the longitudinal axis X,X' of the packaging 1b, this inclination corresponding to the axis X1X1' of the bottles 8. Each oblong recess 37b corresponds to the position of a bottle 8 in the packaging and therefore, in this embodiment, the double bottom wall 35b has 6 oblong recesses. Each oblong recess 37b is designed to support the body of a bottle 8, ensuring its positioning against the double bottom wall 35b and increasing the secure retention of the bottles 8 in the packaging 1b.

[0048] In this second embodiment, the packaging 1b further comprises an upper closing wall 33b connected by a longitudinal fold line 34b to the longitudinal wall 4b of the perimeter wall 3b opposite the one connected to the double bottom wall 35b. The upper closing wall 33b has a dimension substantially equal to the bottom wall 2b and the double bottom wall 35b. The upper closing wall 33b is connected by a fold line 39b to a sealing wall 41b intended, by means known to those skilled in the art, to seal the closing of packaging 1b.

[0049] The assembly operations for packaging 1b are identical to those described with reference to packaging 1b, except that after assembling the base 2b and the perimeter wall 3b, the double bottom wall 35b is brought against the base wall 2b. The six bottles 8 are then positioned diagonally on the double bottom wall 35b ([Fig. 10]). The cover walls 11b, 12b are then positioned in the same way as for packaging 1a of the first embodiment. With reference to [Fig. 13], the closure of packaging 1b is achieved by bringing the upper closure wall 33b onto the two cover walls 11b, 12b and inserting the sealing wall 40b between the inner face of the opposite longitudinal wall 4b and the connecting wall 31b of the double bottom wall 35b. The sealing means include tabs 42b whose insertion into coincident slots allows the closure of the package 1b to be sealed.

[0050] The third embodiment illustrated in Figures 13 to 20 provides for the packaging of two tiers of bottles, with six bottles per tier. To achieve this, the double bottom wall 35b of the second embodiment is replaced by two cover walls 11c', 12c' identical to those previously described for the first two embodiments, which secure the lower tier of bottles 8 in position. The packaging also includes two other cover walls 11c, 12c designed like the cover walls 11a, 11b; 12a, 12b of the first and second embodiments, which secure the bottles 8 of the upper tier in position.

[0051] The third embodiment includes a number of elements in common with the first and second embodiments which will not be repeated in detail in the following description.This is the case for the four sides 2c1, 2c2, 2c3, 2c4, the bottom wall 2c, the perimeter wall 3b, the parallel longitudinal walls 4c, the folding lines 5c, 7c, the rows 9c, 10c of bottles which will apply to the two tiers of bottles 8, the two cover walls 11c, 12c of the upper tier, the main bodies 13c, 14c and the free edges for retaining the bottles 15c, 16c of these cover walls 11c, 12c, the associated folding lines 17c, 18c, 19c, 20c, the longitudinal retaining tabs for the bottles 21c, 22c, the associated folding lines 29c, 30c and their continuous curved edge 45c, 46c, the opposing lateral tabs for securing 27c, 28c, lateral retaining tabs for the body of two adjacent bottles 23c, 24c and associated inclined folding lines 25c, 26c always relative to the two covering walls 11, 12c of the upper tier of bottles. .

[0052] According to the third embodiment, the bottom wall 2c and the perimeter wall 3c are intended to house two tiers of six bottles 8 oriented head- spade by defining, for each floor, two rows of bottles 9'c; 10'c, the axes XI,XL of the bottles 8 being both parallel to each other, arranged in a plane parallel to the bottom wall 2c, and inclined with respect to the longitudinal axis XX' of the packaging le.

[0053] The packaging comprises two covering walls of the lower tier 1l'e, 12'c, each connected by a longitudinal fold line 17'c, 18'c to a connecting wall 31c, itself connected by a longitudinal fold line 32c to a longitudinal wall 4c of the perimeter wall 3c. Unlike the configuration of the second embodiment, the height of the connecting wall 31c is less than the height of the longitudinal walls 4c. More precisely, the height of the connecting wall 31c is approximately half the height of the longitudinal walls 4c, so that, in the operating position, the two covering walls of the lower tier 1l'e, 12'c are substantially parallel to the bottom wall 2c, resting on the bottles 8 of the lower tier.In this position of use, the connecting wall 31c comes against the inner face of the longitudinal wall 4c to which it is connected, the two covering walls of the lower stage 11'e, 12'c thus forming the bottom wall of the upper stage of bottles 8.

[0054] The two cover walls of the lower level 11'e, 12'c are identical to the cover walls 11a, 12a; 11b, 12b of the first and second embodiments with regard to the main bodies 13'c, 14'c, the free edges for retaining bottles 15'c, 16'c, the three longitudinal retaining tabs for the bottles 21'c, 22'c, and the opposing lateral securing tabs 27'c, 28'c associated with each longitudinal retaining tab for bottles 21'c, 22'c. Reference is therefore made, for these elements, to the description given with reference to the first embodiment. As with the first and second embodiments, in the position of use, the longitudinal retaining tabs for bottles 21'c, 22'c extend longitudinally into the packaging.Although the two covering walls of the lower floor ll'c, 12'c are not directly connected to the side walls 6c, they extend, in the position of use, from these side walls 6c towards the opposite side wall 6c.

[0055] The two covering walls of the lower level 11'c, 12'c have lateral retaining tabs for the bodies of two adjacent bottles 23'c, 24'c, the arrangement of which differs substantially from those of the first and second embodiments, as well as from those of the covering walls of the upper level 11c, 12c. To this end, each main body 13'c, 14'c of the covering wall of the associated lower level 11'c, 12' has two lateral retaining tabs for the bodies of two adjacent bottles 23'c, 24'c, each being provided in a single slot and pivotally mounted around an associated fold line 25c', 26c'. The dimension of Each opening corresponds to the dimension of the associated lateral retaining tab 23'c, 24'c. Furthermore, considering the two openings of the same main body 13'c, 14'c, the respective fold lines 25c', 26c' are located on the center side of the main body 13'c, 14'c, opposite its longitudinal edges. Thus, and as illustrated in particular in [Fig. 18], when the two lateral retaining tabs of the body of two adjacent bottles 23'c, 24'c of a cover wall 11'c, 12'c are in the operating position, after pivoting around their respective fold lines 25c', 26c', the lateral retaining tabs of the body of two adjacent bottles 23'c, 24'c are arranged on either side of the central bottle of the row of bottles considered 9'c, 10'c.

[0056] Furthermore, each cover wall of the lower level 11'c, 12'c has a second transverse fold line 43'c, 44'c which is parallel to the first transverse fold line 19'c, 20'c and coincides with the edge of the openings of the lateral retaining tabs of the body of two adjacent bottles 23'c, 24'c, which is located closest to the associated free edge of the bottle retainers 15'c, 16'c. This second transverse fold line 43'c, 44'c contributes to folding the free edge of the bottle retainers 15'c, 16'c relative to the main body 13'c, 14'c of the associated cover wall 11'c, 12'c. This second fold line advantageously ensures the easy positioning of the free edge of the bottle retainers 15'c, 16'c towards its position of use, as will be described later.

[0057] As regards the two covering walls of the upper floor 1 le, 12c, these are designed like the covering walls 1 la,12a ;1 lb,12b of the first and second embodiments by each being connected by a lateral fold line 17c, 18c to a corresponding lateral wall 6c of the perimeter wall 3c.

[0058] Finally, the upper closing wall 33c is identical to that of the second embodiment, including with regard to the sealing wall 41c connected to the closing wall 33c by a fold line 39b and also the sealing tabs 42c.

[0059] The assembly operations of the packaging of the third embodiment are described below.

[0060] Starting from the side shown in [Fig. 14], the four panels 2c1, 2c2, 2c3, 2c4 are assembled to form the base 2c, which leads simultaneously to the construction of the perimeter wall 3c around the base 2c. The assembly is held together by means known to those skilled in the art.

[0061] Once the base 2c and the perimeter wall 3c are mounted, the six bottles defining the lower tier of bottles are installed on the base ([Fig. 16]) oriented head-to-tail and defining two rows 9'c, 10'c of bottles, the axes XI, XI' of the bottles 8 being both parallel to each other, arranged in a plane parallel to the base wall 2c and inclined with respect to the longitudinal axis XX' of the packaging 1.

[0062] Prior to the installation of the cover walls 11'c,12'c, the lateral retaining tabs of the body of two adjacent bottles 23'c,24'c are brought to pivot with respect to the associated folding lines 25'c,26'c substantially perpendicular to the main body 13'c,14'c of the cover walls of the upper stage 11'c,12'c.

[0063] With reference to [Fig. 17], the cover walls 11'c, 12'c are brought onto the bottles 8 of the lower tier by folding the fold lines 18'c, 32b, the connecting wall 31c coming against the inner face of the longitudinal wall 4c to which it is connected via the connecting wall 31c. The two cover walls of the lower tier 11'c, 12'c thus form the bottom wall of the upper tier of bottles 8. Simultaneously, the lateral retaining tabs of the body of two adjacent bottles 23'c, 24'c are positioned between two adjacent bottle bodies 8.

[0064] Simultaneously, the free retaining edges of the bottles 15'c, 16'c are pivoted relative to the first 19'c, 20'c and second 43'c, 44'c associated folding lines. The second folding lines 43'c, 44'c allow for additional movement to position the free retaining edges of the bottles 15'c, 16'c ([Fig. 17]). The free retaining edges of the bottles 15'c, 16'c are thus, in their active holding position, substantially perpendicular to the bottom wall 2c. During this pivoting, the longitudinal retaining tabs of the bottles 21'c, 22'c are positioned against the ends of the bottles 8 of the opposite row 9'c, 10'c.

[0065] As regards the shims 27'c,28'c, prior to pivoting the free edge of the bottle retainers 15'c,16'c, they can be pivoted around the associated folding line 29'c,30'c to ensure their positioning the shoulder and the ring of two adjacent bottles 8 of the two rows of opposite bottles.

[0066] With the two covering walls of the lower tier 1 l'c, 12'c thus in place, forming the bottom wall of the upper tier of bottles 8, the six bottles of the upper tier are installed on said covering walls of the lower tier 1 l'c, 12'c. The procedure is then followed as for the first and second embodiments to bring the two covering walls of the upper tier 1 l'c, 12'c onto the upper tier of bottles 8.

[0067] The closure of the packaging is carried out, as for the second embodiment, by bringing the upper closing wall 33c onto the two covering walls of the upper stage 1, 12c and by inserting the sealing wall 40b against the connecting wall 31c of the covering walls of the lower stage 1, 12c.
