Description

La présente invention concerne un corps creux en matière thermoplastique biorientée présentant un axe longitudinal de symétrie et comportant un col cylindrique, une paroi latérale de forme généralement cylindrique et un fond comportant une partie centrale en forme de dôme rentrant raccordée à la paroi latérale par une moulure périphérique arquée formant surface d'appui pour le corps creux en position verticale tel qu'une bouteille ou un récipient analogueoThe present invention relates to a hollow body of bioriented thermoplastic material having a longitudinal axis of symmetry and comprising a cylindrical neck, a side wall of generally cylindrical shape and a bottom comprising a central part in the shape of a re-entrant dome connected to the side wall by a molding arched device forming a support surface for the hollow body in a vertical position such as a bottle or a similar container

Actuellement, il est fait de plus en plus souvent appel aux matières thermoplastiques pour la réalisation des corps creux tels que des bouteilles utilisées pour le conditionnement des liquides. Afin d'accroître la résistance mécanique des corps creux, ceux-ci sont de plus en plus souvent moulés par soufflage dans des conditions, de température notamment, conduisant à l'orientation, et, de préférence, à la biorientation suivant deux directions orthogonales, des macromolécules de leur matériau constitutif.Currently, thermoplastics are used more and more often for the production of hollow bodies such as bottles used for packaging liquids. In order to increase the mechanical resistance of the hollow bodies, they are more and more often blow molded under conditions, particularly of temperature, leading to orientation, and preferably to biorientation in two orthogonal directions, macromolecules of their constituent material.

Le choix pour ces corps creux d'un fond présentant une partie centrale en forme de dôme rentrant raccordée à la paroi latérale par une moulure arquée périphérique par laquelle le corps creux prend appui en position verticale est généralement déterminé en vue d'améliorer la stabilité des corps creux en position verticale et la résistance de ces corps creux aux sollicitations par chocs. En général, le diamètre de la partie centrale en forme de dôme rentrant varie entre 30 et 80 X de la valeur du diamètre maximum des corps creux afin de garantir une bonne résistance aux sollicitations par choes.The choice for these hollow bodies of a bottom having a central part in the shape of a re-entrant dome connected to the side wall by a peripheral arcuate molding by which the hollow body is supported in a vertical position is generally determined with a view to improving the stability of the hollow body in vertical position and the resistance of these hollow bodies to impact stresses. In general, the diameter of the central part in the shape of a re-entrant dome varies between 30 and 80 X of the value of the maximum diameter of the bodies hollow in order to guarantee a good resistance to the stresses by choes.

Les corps creux de ce type présentent toutefois un inconvénient sérieux qui découle du fait que le diamètre de la partie rentrante de leur fond est généralement supérieure au diamètre externe de leur col de sorte que ce dernier peut pénétrer de façon importante dans la partie rentrante du fend d'un corps creux similaire. De ce fait, lorsqu'après leur remplissage, ces corps creux sont emballés dans des caisses en carton qui sont ensuite empilées en vue de leur transport ou de leur stockage, les parois en carton qui sont interposées entre deux rangées superposées de corps creux, c'est-à-dire les parois inférieure et supérieure des caisses risquent d'être déformées, par compression, entre les cols et les fonds de ces corps creux et ce, particulièrement, lorsque ces parois sont mouillées. Il en résulte donc une déformation des caisses d'emballage qui risque de compromettre la stabilité des empilages.However, hollow bodies of this type have a serious drawback which results from the fact that the diameter of the re-entrant part of their bottom is generally greater than the external diameter of their neck so that the latter can penetrate significantly into the re-entrant part of the split. of a similar hollow body. Therefore, when after filling, these hollow bodies are packed in cardboard boxes which are then stacked for transport or storage, the cardboard walls which are interposed between two superimposed rows of hollow bodies, c 'That is to say, the lower and upper walls of the boxes may be deformed, by compression, between the necks and the bottoms of these hollow bodies and this, in particular, when these walls are wet. This therefore results in a deformation of the packaging boxes which risks compromising the stability of the stacks.

Après de nombreux essais, il a maintenant été trouvé une conception particulière pour ce type de fond de corps creux qui permet de supprimer cet inconvénient tout en conservant et même en améliorant les autres propriétés avantageuses et notamment la résistance aux sollicitations par chocs.After numerous tests, a particular design has now been found for this type of hollow body bottom which makes it possible to eliminate this drawback while retaining and even improving the other advantageous properties and in particular the resistance to impact stresses.

La présente invention concerne dès lors un corps creux en matière thermoplastique orientée présentant un axe longitudinal de symétrie et comportant un col cylindrique, une paroi latérale de forme générale cylindrique et un fond comportant une partie centrale en forme de dôme rentrant raccordée à la paroi latérale par une moulure périphérique arquée formant surface d'appui pour le corps creux en position verticale dans lequel la partie centrale en forme de dôme rentrant est pourvue d'une pluralité de protubérances en saillies vers l'extérieur du corps creux réparties autour de l'axe longitudinal et dont les sommets sont écartés de cet axe d'une distance au plus égale à 60 % du diamètre externe du col du corps creux.The present invention therefore relates to a hollow body of oriented thermoplastic material having a longitudinal axis of symmetry and comprising a cylindrical neck, a side wall of generally cylindrical shape and a bottom comprising a central part in the form of a re-entrant dome connected to the side wall by an arcuate peripheral molding forming a bearing surface for the hollow body in a vertical position in which the central part in the shape of a re-entrant dome is provided with a plurality of protrusions projecting towards the outside of the hollow body distributed around the longitudinal axis and the vertices of which are spaced from this axis by a distance at most equal to 60% of the external diameter of the neck of the hollow body.

De préférence, ces protubérances sont creuses et sont réalisées directement lors du moulage en utilisant un moule approprié.Preferably, these protrusions are hollow and are made directly during molding using a suitable mold.

Il a en effet été constaté que, contrairement à toute attente, la présence de ces protubérances n'affecte pas la résistance du corps creux aux sollicitations par chocs et, au contraire, qu'elle peur même améliorer cette résistance. En outre, la présence de ces protubérances empêche ou tout au moins limite fortement la possibilité de pénétration du col d'un corps creux dans la partie rentrante dQ fond d'un corps creux similaire et partant supprime le risque de déformation des parois en carton des caisses utilisées pour le regroupement et l'emballage des corps creux.It has in fact been observed that, contrary to all expectations, the presence of these protuberances does not affect the resistance of the hollow body to impact stresses and, on the contrary, that it may even improve this resistance. In addition, the presence of these protuberances prevents or at least strongly limits the possibility of penetration of the neck of a hollow body in the re-entrant portion Q of the bottom of a similar hollow body and therefore eliminates the risk of deformation of the cardboard walls boxes used for grouping and packaging hollow bodies.

Afin de garantir au maximum ce résultat, on préfère généralement que les sommets des protubérances soient au plus écartés de l'axe longitudinal du corps creux d'une distance égale à 50 % du diamètre externe du col du corps creux, cet écart étant le même pour chaque sommet.In order to guarantee this result as much as possible, it is generally preferred that the tops of the protuberances are at most spaced from the longitudinal axis of the hollow body by a distance equal to 50% of the external diameter of the neck of the hollow body, this difference being the same for each vertex.

Les protubérances peuvent présenter un profil quelconque mais sont, de préférence, exemptes d'angles vifs. Dans un mode de réalisation qui est préféré, les protubérances ont l'apparence de cônes à sommet arrondi et dont les axes longitudinaux ou axes directeurs sont parallèles à ou dirigés vers l'axe longitudinal du corps creux. Dans ce dernier cas, les protubérances se rapprochent de cet axe. En général, la base de ces profils coniques est tronquée du fait de l'inclinaison de la partie centrale rentrante du fond du corps creux. Il est toutefois loisible d'aplanir là partie centrale rentrante du fond du corps creux au niveau des protubérances afin de conférer une forme parfaitement conique aux protubérances.The protrusions can have any profile but are preferably free from sharp angles. In an embodiment which is preferred, the protuberances have the appearance of cones with rounded apex and whose longitudinal axes or directing axes are parallel to or directed towards the longitudinal axis of the hollow body. In the latter case, the protrusions approach this axis. In general, the base of these conical profiles is truncated due to the inclination of the re-entrant central part of the bottom of the hollow body. However, it is possible to flatten the reentrant central part of the bottom of the hollow body at the level of the protrusions in order to impart a perfectly conical shape to the protrusions.

Les sections transversales des protubérances peuvent être de forme circulaire comme c'est le cas lorsque les protubérances présentent un profil de forme conique ou être de forme différente. De même ces sections peuvent être constantes ou variables sur toute la hauteur des protubérances. On préfère toutefois que la plus grande largeur de ces sections soit inférieure à 20 % du diamètre maximum du corps creux, les meilleurs résultats étant atteints lorsque cet ce largeur est comprise entre 5 et 15 % de ce diamètre.The cross sections of the protrusions may be circular in shape as is the case when the protrusions have a conical profile or be of different shape. Likewise, these sections can be constant or variable over the entire height of the protrusions. However, it is preferred that the greatest width of these sections is less than 20% of the maximum diameter of the hollow body, the best results being achieved when this width is between 5 and 15% of this diameter.

La hauteur des protubérances est choisie de façon telle que les sommets de ces protubérances soient écartés de la paroi de la partie centrale rentrante du rond dans la région où celle-ci se raccorde à la moulure périphérique arquée. En outre, cette hauteur est, de préférence, choisie de façon telle que les sommets des protubérances soient légèrement en retrait de la surface d'appui du corps creux en position verticale. De prétérence, ce retrait est au plus égal à 10 % du diamètre maximum du corps creux et est le même pour toutes les protubérances.The height of the protrusions is chosen so that the tops of these protrusions are spaced from the wall of the re-entrant central part of the circle in the region where the latter is connected to the arcuate peripheral molding. In addition, this height is preferably chosen so that the tops of the protrusions are slightly set back from the bearing surface of the hollow body in a vertical position. Preferably, this shrinkage is at most equal to 10% of the maximum diameter of the hollow body and is the same for all the protrusions.

Le nombre de protubérances peut être quelconque. En général on préfère cependant que celui-ci varie entre 2 et 6. De très bons résultats ont été obtenus avec des fonds présentant trois protubérances.The number of protrusions can be any. In general, however, it is preferred that it varies between 2 and 6. Very good results have been obtained with bottoms having three protrusions.

De même, on préfère que l'écartement angulaire entre les protubérances successives soit constant. De ce fait, suivant les modes de réalisation préférés de l'invention, les sommets des protubérances sont situés sur un même diamètre du corps creux lorsque le fond comporte deux protubérances et les sommets des protubérances définissent les sommets d'un polygone régulier qui peut être inscrit dans un cercle dont le centre est situé sur l'axe longitudinal du corps creux lorsque le fond est équipé de plus de deux protubérances. Le résultat visé peut cependant néanmoins être atteint lorsque l'écartement angulaire entre les protubérances successives est quelconque et variable.Likewise, it is preferred that the angular spacing between the successive protrusions is constant. Therefore, according to the preferred embodiments of the invention, the vertices of the protrusions are located on the same diameter of the hollow body when the bottom has two protrusions and the vertices of the protrusions define the vertices of a regular polygon which can be inscribed in a circle whose center is located on the longitudinal axis of the hollow body when the bottom is equipped with more than two protrusions. However, the desired result can be achieved when the angular spacing between the successive protrusions is arbitrary and variable.

La moulure périphérique arquée par laquelle le corps creux prend appui peut également être réalisée selon de nombreuses possibilités.The arcuate peripheral molding by which the hollow body bears can also be produced according to many possibilities.

Selon un premier mode de réalisation possible, la moulure périphérique arquée présente un rayon de courbure constant se raccordant tangentiellement avec la paroi latérale et avec la partie centrale du fond. Dans ce cas, le rayon de courbure est généralement compris entre 10 et 25 % du diamètre maximum du corps creux.According to a first possible embodiment, the arcuate peripheral molding has a constant radius of curvature tangentially connecting with the side wall and with the central part of the bottom. In this case, the radius of curvature is generally between 10 and 25% of the maximum diameter of the hollow body.

Selon un second mode de réalisation possible, la moulure arquée périphérique peut présenter deux rayons de courbures constants successifs. Dans ce cas, le premier rayon de courbure correspond à la partie de la moulure qui se raccorde à la paroi latérale et est supérieur au second rayon de courbure qui correspond à la partie de moulure qui se raccorde à la partie centrale du fond. Ces deux rayons de courbure successifs sont choisis de préférence de façon telle que la moulure périphérique ne présente pas de point d'inflexion et qu'elle se raccorde tangentiellement de part et d'autre avec la paroi latérale et avec la partie centrale du fond. La valeur du premier rayon de courbure est de préférence comprise entre 50 et 200 7 du diamètre maximum du corps creux et celle du second rayon de courbure entre 10 et 25 % de ce même diamètre.According to a second possible embodiment, the peripheral arcuate molding can have two successive radii of constant curvature. In this case, the first radius of curvature corresponds to the part of the molding which connects to the side wall and is greater than the second radius of curvature which corresponds to the molding part which connects to the central part of the bottom. These two successive radii of curvature are preferably chosen in such a way that the peripheral molding has no point of inflection and that it tangentially connects on either side with the side wall and with the central part of the bottom. The value of the first radius of curvature is preferably between 50 and 200% of the maximum diameter of the hollow body and that of the second radius of curvature between 10 and 25% of this same diameter.

La moulure périphérique peut cependant avoir d'autres profils que les deux qui viennent d'être décrits. En particulier cette moulure peut présenter un rayon de courbure variable.The peripheral molding may however have other profiles than the two which have just been described. In particular, this molding can have a variable radius of curvature.

Il est également loisible de prévoir une zone annulaire pratiquement plane sur cette moulure qui peut être exploitée pour la gravure d'inscriptions en relief indiquant par exemple la contenance du corps creux, le nom commercial de son producteur ou de son utilisateur, une marque ou un avertissement. La largeur d'une telle zone annulaire est comprise, en général, entre 10 et 40 % du diamètre maximum du corps creux et, de préférence, entre 15 et 30 % de ce diamètre.It is also possible to provide a practically flat annular zone on this molding which can be used for engraving inscriptions in relief indicating for example the capacity of the hollow body, the trade name of its producer or of its user, a brand or a Warning. The width of such an annular zone is generally between 10 and 40% of the maximum diameter of the hollow body and, preferably, between 15 and 30% of this diameter.

La partie centrale en forme de dôme rentrant peut avoir une allure générale quelconque, elle peut par exemple être tronconique et sphérique à son sommet. Cependant, une forme en calotte sphérique est préférée. Le plus grand diamètre de cette partie centrale rentrante est en général compris entre 15 et 60 % du diamètre maximum du corps creux.The central part in the shape of a domed dome can have any general appearance, it can for example be frustoconical and spherical at its top. However, a spherical cap shape is preferred. The largest diameter of this re-entrant central part is generally between 15 and 60% of the maximum diameter of the hollow body.

Le corps creux conforme à l'invention présente, ainsi qu'il a été dit, une paroi latérale de forme cylindrique. Cependant cette paroi ne doit pas nécessairement présenter une symétrie de révolution parfaite. Il est possible que la forme de cette paroi s'écarte de la forme d'un cylindre parfait. Ainsi, le corps creux peut avoir une section elliptique ou polygonale. Dans ce cas, on préfère que la plus grande dimension des sections perpendiculaires à l'axe du corps creux n'excède pas le double de la plus petite.The hollow body according to the invention has, as has been said, a side wall of cylindrical shape. However, this wall does not necessarily have to have perfect symmetry of revolution. It is possible that the shape of this wall deviates from the shape of a perfect cylinder. Thus, the hollow body can have an elliptical or polygonal section. In this case, it is preferred that the largest dimension of the sections perpendicular to the axis of the hollow body does not exceed twice the smallest.

La corps creux conforme à l'invention peut être réalisé à partir d'une matière thermoplastique quelconque. A titre d'exemples de matières thermoplastiques utilisables, on peut citer les résines à base de chlorure de vinyle, les polymères et les copolymères produits à partir d'alpra-oléfines contenant jusqu'à huit aromes de carbone dans leur molécule, les polymères et copolymères acryliques et notamment ceux produits â partir du nitrile acrylique, les polyesters tels que le polytéréphtalate d'éthylèneglycol, et les polycarbonates.The hollow body according to the invention can be made from any thermoplastic material. As examples of thermoplastic materials which can be used, mention may be made of vinyl chloride-based resins, polymers and copolymers produced from alpha-olefins containing up to eight carbon aromas in their molecule, polymers and acrylic copolymers and especially those produced from acrylic nitrile, polyesters such as polyethylene terephthalate, and polycarbonates.

Le corps creux conforme à l'invention peut être produit par toute technique connue, et notamment par les techniques de moulage par injection-soufflage et de moulage par extrusion soufflée, conduisant à la réalisation de corps creux moléculairement orientés.The hollow body according to the invention can be produced by any known technique, and in particular by injection blow-molding and blow-molding techniques, leading to the production of molecularly oriented hollow bodies.

Les corps creux suivant l'invention présentent des propriétés mécaniques remarquables qui les rendent aptes à être utilisés même pour le conditionnement sous pression de boissons carbonatées telles que la bière et les limonades.The hollow bodies according to the invention have remarkable mechanical properties which make them suitable for use even for the packaging under pressure of carbonated drinks such as beer and lemonades.

Le corps creux en matière thermoplastique conforme à l'invention est, par ailleurs, illustré par les figures 1 et 2 des dessins annexés qui représentent un corps creux suivant une forme de réalisation de l'invention.The hollow body of thermoplastic material according to the invention is also illustrated by Figures 1 and 2 of the accompanying drawings which show a hollow body according to one embodiment of the invention.

Dans ces dessins qui sont donnés à titre purement illustratif :

  • - la fig.l est une vue par en dessous d'un corps creux conforme à l'invention
  • - la fig.2 est une vue partielle en élévation et en coupe suivant l'axe AA' de la fig.l.
In these drawings which are given purely by way of illustration:
  • - Fig.l is a view from below of a hollow body according to the invention
  • - Fig.2 is a partial elevational view in section along the axis AA 'of fig.l.

Ainsi qu'il apparaît sur les figures et 2, le corps creux 1 conforme à l'invention comporte une paroi latérale 2 de forme générale cylindrique, un col fileté ou non (non représenté) et un fond constitué d'une partie centrale 4 en forme de dôme rentrant raccordée à la paroi latérale 2 par une moulure périphérique arquée 3. La moulure arquée 3 présente deux rayons de courbure différents R1 et R2, le rayon R1 étant nettement plus grand que le rayon R2.As shown in Figures and 2, the hollow body 1 according to the invention comprises a side wall 2 of generally cylindrical shape, a threaded neck or not (not shown) and a bottom consisting of a central part 4 in reentrant dome shape connected to the side wall 2 by an arcuate peripheral molding 3. The arcuate molding 3 has two different radii of curvature R 1 and R 2 , the radius R 1 being significantly larger than the radius R 2 .

Conformément à l'invention, la partie centrale 4 est pourvue de trois protubérances 6 qui sont creuses et équidistantes et qui sont formées lors du moulage du corps creux 1. Ces protubérances présentent la forme générale d'un cône à sommet arrondi dont l'axe longitudinal est parallèle à l'axe longitudinal CC' du corps creux. En outre, le sommet des protubérances est écarté de la paroi de la partie rentrante 4 du fond dans la région 5 où celle-ci se raccorde à la moulure périphérique 3.According to the invention, the central part 4 is provided with three protrusions 6 which are hollow and equidistant and which are formed during the molding of the hollow body 1. These protrusions have the general shape of a cone with a rounded top whose longitudinal axis is parallel to the longitudinal axis CC 'of the hollow body. In addition, the top of the protrusions is spaced from the wall of the re-entrant part 4 of the bottom in the region 5 where the latter is connected to the peripheral molding 3.

La hauteur des protubérances est telle que le sommet de ces protubérances soit écarté 'de la surface d'appui 7 du corps creux 1 en position verticale d'une distance d au plus égal à 10 % du diamètre maximum D max. du corps creux.The height of the protrusions is such that the top of these protrusions is spaced from the bearing surface 7 of the hollow body 1 in a vertical position by a distance d at most equal to 10% of the maximum diameter D max. of the hollow body.

Les sommets des protubérances définissent les sommets d'un triangle équilatéral qui s'inscrit dans un cercle dont le centre est situé sur l'axe longitudinal CC' du corps creux 1.The vertices of the protrusions define the vertices of an equilateral triangle which is inscribed in a circle whose center is located on the longitudinal axis CC 'of the hollow body 1.

Afin de mieux faire apparaître les avantages obtenus grâce au corps creux conforme à l'invention, on a réalisé trois séries de flacons orientés d'une contenance de 1,5 1 en les dotant d'un fond suivant les fig. 1 et 2, c'est-à-dire d'un fond conforme à l'invention ou d'autres fonds représentés aux fig. 3 ou 4 des dessins annexés. Ces derniers fonds sont exclus du cadre de l'invention. La matière thermoplastique mise en oeuvre est du polychlorure de vinyle rigide. Les conditions opératoires, en particulier les paramètres régissant l'orientation sont les mêmes pour les trois séries de flacons.In order to better show the advantages obtained thanks to the hollow body according to the invention, three series of oriented bottles with a capacity of 1.5 l have been produced by providing them with a bottom according to FIGS. 1 and 2, that is to say of a base according to the invention or of other funds shown in FIGS. 3 or 4 of the accompanying drawings. These latter funds are excluded from the scope of the invention. The thermoplastic material used is rigid polyvinyl chloride. The operating conditions, in particular the parameters governing the orientation, are the same for the three series of bottles.

Le fond suivant la fig. 3 est constitué successivement a partir de la périphérie par une moulure arquée périphérique 8 de raccordement à la paroi latérale, par une zone annulaire 9 sensiblement plane se raccordant à la moulure arqùée périphérique et par une partie centrale 10 en forme de dôme rentrant de diamètre relativement faible.The bottom according to fig. 3 is formed successively from the periphery by a peripheral arcuate molding 8 for connection to the side wall, by a substantially planar annular zone 9 connecting to the peripheral arcuate molding and by a central portion 10 in the form of a re-entrant dome of relatively diameter low.

Le fond suivant la fig. 4 est constitué par trois moulures successives alternées de rayon constant.The bottom according to fig. 4 is constituted by three successive alternating moldings of constant radius.

Des séries de flacons ainsi obtenus sont ensuite remplis et obturés de façon identique puis ils sont soumis à 15°C aux deux essais de résistance aux chocs décrits ci-après.Series of bottles thus obtained are then filled and closed identically, then they are subjected to 15 ° C to the two impact resistance tests described below.

Dans un premier essai, on laisse tomber les flacons remplis en position verticale sur un socle en béton incliné de 5" par rapport à l'horizontale, la hauteur de chute étant de 0,70 m ou de 1,10 m. Ce test permet de juger de la résistance des flacons en cas de chute accidentelle d'une table ou d'un rayon d'exposition.In a first test, the filled bottles are dropped in a vertical position on a concrete base inclined 5 "from the horizontal, the drop height being 0.70 m or 1.10 m. This test allows to judge the resistance of the vials in the event of an accidental fall of a table or shelf.

Dans le second essai, le flacon est attaché à l'extrémité d'un pendule et heurte une paroi verticale en béton avec une énergie potentielle de 14,710 Nm.. Ce test permet de juger de la résistance des flacons en cas de heurts accidentels tels que ceux occasionnés, par exemple, lors de l'accrochage des wagons de chemin de fer assurant leur transport vers les lieux de distribution.In the second test, the bottle is attached to the end of a pendulum and strikes a vertical concrete wall with a potential energy of 14,710 Nm. This test makes it possible to judge the resistance of the bottles in the event of accidental knocks such as those occasioned, for example, during the hanging of railway wagons ensuring their transport to the places of distribution.

Les résultats enregistrés lors de ces essais sont repris au tableau 1 ci-après. Les nombres indiqués en regard des deux types d'essais donnent le nombre de flacons cassés sur 100 soumis à l'essai.

Figure imgb0004
The results recorded during these tests are shown in Table 1 below. The numbers shown opposite the two types of tests give the number of broken vials out of 100 tested.
Figure imgb0004

On constate directement que les flacons conformes à l'invention (fig.1, 2) présentent une résistance aux chocs nettement améliorée.It can be seen directly that the bottles according to the invention (fig.1, 2) have a significantly improved impact resistance.

Par ailleurs, des flacons remplis et obturés conformes à l'invention sont regroupés par 12 dans des caisses en carton habituellement utilisées pour leur stockage et leur transport. Les caisses sont ensuite empilées sous quatre rangées. Après un stockage de 60 jours on constate que les caisses en carton ne présentent aucune déformation dans leurs faces inférieure et supérieure.Furthermore, filled and closed bottles according to the invention are grouped by 12 in cardboard boxes usually used for their storage and transport. The boxes are then stacked in four rows. After storage for 60 days, it can be seen that the cardboard boxes show no deformation in their lower and upper faces.
