Abstract

The invention relates to a method for temporarily increasing the resistance to vertical compression of a bag for transporting and holding liquids and quasi-liquids, intended for a bag having the general shape of a cube and including receptacles at each of the corners thereof. The method consists in choosing four inflatable cushioning pouches for each bag, said pouches being elongate and having length, width and extension dimensions corresponding to the length, width and internal volume of the receptacles in the bag. Next, the four cushioning pouches are introduced into the four receptacles and are subsequently inflated, thereby trapping same in a vertical position in which they can resist compression along the vertical axis thereof. The resulting bag is characterised in that the receptacles in the four corners of the bag are each provided internally with a cushioning pouch which is optionally rigidly secured to the bag.

Description

PROCEDE POUR AUGMENTER TEMPORAIREMENT LA RESISTANCE A LA COMPRESSION VERTICALE D'UN SAC POUR LE TRANSPORT ET LA MANUTENTION DE LIQUIDES ET QUASI LIQUIDES, ET SAC ISSU DU PROCEDE.  METHOD FOR TEMPORARILY INCREASING THE RESISTANCE TO THE VERTICAL COMPRESSION OF A BAG FOR THE TRANSPORT AND HANDLING OF LIQUIDS AND QUASI LIQUIDS, AND BAG OBTAINED FROM THE PROCESS
La présente invention concerne un procédé pour augmenter temporairement la résistance verticale à la compression d'un sac pour le transport et la manutention de substances liquides ou quasi liquides. Elle concerne aussi un sac issu de la mise en œuvre du procédé. The present invention relates to a method for temporarily increasing the vertical compressive strength of a bag for the transport and handling of liquid or quasi-liquid substances. It also relates to a bag resulting from the implementation of the method.
Le transport à l'échelle industrielle de substances liquides et quasi liquides, en particulier les concentrés de jus de fruits par exemple, représente une branche importante du commerce mondial. Pour transporter de telles substances, la première idée qui vient à l'esprit est de les placer dans des conteneurs rigides tels que de citernes aux parois métalliques ou en matière plastique. The industrial scale transport of liquid and quasi-liquid substances, particularly fruit juice concentrates for example, is an important branch of world trade. To transport such substances, the first idea that comes to mind is to place them in rigid containers such as tanks with metal walls or plastic.
Cependant, de tels conteneurs rigides ont un inconvénient majeur, à savoir qu'ils occupent le même volume lorsqu'ils sont vides que lorsqu'ils sont pleins. Transporter des conteneurs vides sur de très longues distances pour les retourner au point de remplissage est économiquement et écologiquement absurde. C'est pourquoi la préférence va logiquement, depuis qu'ils sont disponibles, à des conteneurs souples que l'on peut déployer pour les remplir ou au contraire replier pour donner lieu à un encombrement minimum lors du voyage de retour vers le lieu de remplissage. However, such rigid containers have a major disadvantage, namely that they occupy the same volume when empty as when they are full. Carrying empty containers over very long distances to return them to the filling point is economically and ecologically absurd. That is why the preference goes logically, since they are available, to flexible containers that can be deployed to fill them or on the contrary to fold to give rise to a minimum space requirement during the return trip to the filling location .
Un tel conteneur souple est connu en particulier du document WO Such a flexible container is known in particular from the WO document
2009/010928 A2 qui présente en bref une enveloppe externe formée de coupons de toile assemblés formant grosso mode un sac grossièrement cubique dans lequel prend place une seconde enveloppe, un liner, destiné à être rempli d'une substance liquide ou quasi liquide. Les quatre côtés de l'enveloppe externe sont réalisés en toile double et compartimentée de manière à pouvoir recevoir des plaques de renfort. Les quatre arêtes verticales du sac formant l'enveloppe extérieure sont séparées du liner par des bandes de toiles cousues verticalement parallèlement aux dites arêtes, cela dans le but de lutter contre la tendance du sac une fois rempli de former un bombage vers l'extérieur sous la pression du liquide qu'il contient. 2009/010928 A2 which presents in short an outer envelope formed of assembled fabric coupons forming roughly a coarse cubic bag in which takes place a second envelope, a liner, intended to be filled with a liquid or quasi-liquid substance. The four sides of the outer shell are made of double fabric and compartmentalized in order to be able to receive reinforcing plates. The four vertical edges of the bag forming the outer envelope are separated from the liner by vertically sewn webs parallel to said ridges, in order to combat the tendency of the bag once filled to bend outwards under the pressure of the liquid it contains.
Le commerce des substances liquides ou quasi liquides, et en particulier celui des concentrés de jus de fruits, a ceci de particulier que la quantité de liquide effectivement transportée dans un conteneur dépend rarement du volume interne maximum du conteneur. On ne remplit pas le conteneur jusqu'à raz bord, on le remplit en fonction de la commande à satisfaire ou du volume de liquide disponible dans la cuve à vider. Pour cette raison, en majorité, les conteneurs (souples ou non) ne voyagent que partiellement remplis et non à pleine capacité. The trade in liquid or quasi-liquid substances, and in particular that of fruit juice concentrates, has the particularity that the quantity of liquid actually transported in a container rarely depends on the maximum internal volume of the container. The container is not filled to the brim, it is filled according to the order to be satisfied or the volume of liquid available in the tank to be emptied. For this reason, for the most part, containers (flexible or not) travel only partially filled and not at full capacity.
Les conteneurs rigides ont bien des inconvénients, qu'on a mentionnés, mais ils ont sur les conteneurs souples un avantage, à savoir que même remplis partiellement, on peut les superposer, en empiler deux ou trois l'un sur l'autre. L'empilement de conteneurs souples, surtout partiellement remplis représente donc un problème, résolu jusqu'ici par l'emploi de caisses en bois dans lesquels les conteneurs souples sont déposés en vue de leur transport. Rigid containers have many drawbacks, which have been mentioned, but they have an advantage over flexible containers, namely that even when partially filled, they can be stacked, stacked two or three on top of one another. The stack of flexible containers, especially partially filled is therefore a problem, solved so far by the use of wooden boxes in which the flexible containers are deposited for transport.
Sachant que le poids d'une telle caisse peut atteindre les 100 kilos pour chaque conteneur, il y aurait à tous égards une sérieuse économie à pouvoir s'en affranchir. Knowing that the weight of such a box can reach 100 kilos for each container, there would be in all respects a serious economy to be able to emancipate.
La présente invention a pour but d'augmenter temporairement la résistance verticale à la compression d'un sac pour le transport et la manutention de substances liquides ou quasi liquides, cela de manière à permettre leur empilement et donc éliminer la nécessité d'utiliser des caisses à cette seule fin. Dans ce but, le procédé pour augmenter temporairement la résistance à la compression verticale d'un sac pour le transport et la manutention de liquides et quasi liquides, ledit sac, comprenant un liner et des réserves, se distingue par le fait que l'on choisit pour chaque sac des coussins de calage gonflables de forme allongée dont les dimensions de longueur, largeur et déploiement sont en rapport avec la longueur, la largeur et le volume intérieur des réserves du sac et en ce que l'on introduit lesdits coussins de calage dans les réserves, aux fins de gonfler ensuite les coussins et ce faisant les The present invention aims to temporarily increase the vertical compressive strength of a bag for the transport and handling of liquid or quasi-liquid substances, so as to allow their stacking and thus eliminate the need to use crates for this purpose alone. For this purpose, the method for temporarily increasing the vertical compressive strength of a bag for the transport and handling of liquids and quasi-liquids, said bag, comprising a liner and reserves, is distinguished by the fact that chooses for each bag elongate inflatable cushioning cushions whose dimensions of length, width and deployment are related to the length, width and internal volume of the bag's reserves and in that said cushioning cushions are introduced in the reserves, for the purpose of inflating the cushions and, in so doing,
emprisonner dans une position verticale leur permettant d'exercer une résistance à la compression selon leur axe vertical. Le but de la présente invention est aussi de proposer un sac issu de l'application du procédé dont la particularité est que les réserves présentes aux coins du sac sont garnies chacune en leur intérieur d'un coussin de calage, solidarisé ou non avec le sac. imprison in a vertical position allowing them to exert compressive strength along their vertical axis. The object of the present invention is also to propose a bag resulting from the application of the method, the particularity of which is that the reserves present at the corners of the bag are each lined inside with a cushion cushion, secured or not with the bag .
Selon un mode d'exécution, le sac est de forme généralement cubique et comprend des réserves en chacun de ses coins. Le sac peut comporter quatre réserves, l'une à chaque coin dudit sac. Selon un mode d'exécution, on choisit quatre coussins de calage pour chaque sac. According to one embodiment, the bag is of generally cubic shape and includes reserves in each of its corners. The bag may have four reserves, one at each corner of said bag. According to one embodiment, four cushioning cushions are chosen for each bag.
Selon un mode d'exécution, on introduit au moins un sac de calage par réserve. According to one embodiment, at least one storage bag is introduced by reserve.
Selon un mode d'exécution, les coussins de calage comprennent deux films, par exemple de polyéthylène, soudés l'un à l'autre et une valve de According to one embodiment, the cushioning cushions comprise two films, for example polyethylene, welded to one another and a valve of
gonflage/dégonflage. La description qui suit se réfère au dessin dans lequel la figure 1 représente une vue en perspective partiellement éclatée illustrant l'application du procédé selon l'invention. Sur la figure 1 , on reconnaît un sac pour le transport et la manutention de substances liquides ou quasi liquides réalisé selon l'enseignement du document WO 2009/010928. On reconnaît ainsi le sac 1 , dont les quatre côtés sont réalisés en toile double. Chaque côté du sac comporte trois sections délimitées par deux coutures verticales en l'on peut voir un panneau de renfort 2, introduit entre les deux pièces de toile de chacune des trois sections. On observe que les quatre coins du sac possèdent des réserves 3, formant des parallélépipèdes de section triangulaire, et que la bouche supérieure de ces quatre réserves est libre et non fermée. inflation / deflation. The following description refers to the drawing in which Figure 1 shows a partially exploded perspective view illustrating the application of the method according to the invention. In Figure 1, there is recognized a bag for the transport and handling of liquid or quasi-liquid substances made according to the teaching of WO 2009/010928. We recognize the bag 1, whose four sides are made of double canvas. Each side of the bag has three sections delimited by two vertical seams in which can be seen a reinforcing panel 2, introduced between the two pieces of fabric of each of the three sections. It is observed that the four corners of the bag have reserves 3, forming parallelepipeds of triangular section, and that the upper mouth of these four reserves is free and not closed.
C'est l'espace constitué des quatre réserves qui peut être occupé par d'éventuels organes destinés à rendre possible l'empilement des sacs. Il convient de garder à l'esprit que tout l'intérieur du sac, sa partie centrale, est occupé par un liner destiné à être rempli du liquide à transporter. It is the space made up of the four reserves which can be occupied by possible organs intended to make possible the stacking of the bags. It should be borne in mind that the entire interior of the bag, its central part, is occupied by a liner intended to be filled with the liquid to be transported.
On pourrait certes songer à introduire dans les réserves des armatures supplémentaires, par exemple des rondins de taille adaptée, mais il est beaucoup plus élégant de ne pas alourdir le poids total transporté tout en obtenant le résultat espéré. One could certainly think of introducing additional reinforcement into the reserves, for example logs of suitable size, but it is much more elegant not to weigh down the total weight transported while obtaining the expected result.
Or il se trouve que dans le monde des transports, notamment portuaires, on utilise des coussins de calage gonflables (dunnage bags) pour stabiliser les charges à l'intérieur par exemple des grands containers ISO de 40 pieds. Ces coussins, lorsqu'ils sont dégonflés, ressemblent à une taie d'oreiller vide et plate. Ces coussins sont réalisés à l'aide de deux films de polyéthylène soudés l'un à l'autre sur tout leur pourtour et sont munis d'une valve de gonflage et dégonflage. Lorsqu'ils sont gonflés avec de l'air comprimé, ces coussins se présentent comme de gros oreillers particulièrement joufflus. Diverses tailles et formes de tels coussins gonflables sont disponibles sur le marché. However, it happens that in the world of transport, including ports, inflatable cushioning bags (dunnage bags) are used to stabilize the loads inside, for example large 40-foot ISO containers. These cushions, when deflated, look like an empty, flat pillowcase. These cushions are made using two polyethylene films welded to each other all around their circumference and are equipped with an inflation and deflation valve. When inflated with compressed air, these cushions are large, particularly chubby pillows. Various sizes and shapes of such airbags are available on the market.
Ces coussins sont très résistants et la pression interne peut être suffisamment élevée pour qu'ils soient durs comme de la pierre. These cushions are very strong and the internal pressure can be high enough to be hard as stone.
Dans tous les cas d'application normale, ces coussins sont utilisés pour occuper latéralement de la place entre deux charges, de manière à les écarter l'une de l'autre selon un axe horizontal déterminé par le centre des deux faces du coussin. En revanche, rien n'invite, tout au contraire, à exploiter les propriétés de ces coussins selon un autre axe que celui-là. In all cases of normal application, these cushions are used to occupy laterally space between two charges, so as to separate them from each other along a horizontal axis determined by the center of the two faces of the cushion. On the other hand, nothing invites, on the contrary, to exploit the properties of these cushions along another axis than this one.
C'est pourtant cette idée qui est la clé du procédé selon l'invention. On voit sur la figure 1 qu'on a choisi un coussin de calage 4 dont les mensurations correspondent en hauteur et largeur à celle des réserves 3. On choisit aussi le coussin en fonction de la position de sa valve de gonflage 5, que l'on souhaite proche d'une extrémité longitudinale du coussin. Quatre coussins sont retenus pour chaque sac et chacun d'eux est introduit, dégonflé, dans l'une des quatre réserves 3. However, this idea is the key to the process according to the invention. FIG. 1 shows that a wedging cushion 4 has been chosen whose measurements correspond in height and width to that of the reserves 3. The cushion is also chosen according to the position of its inflation valve 5, that the it is desired near a longitudinal end of the cushion. Four cushions are retained for each bag and each of them is introduced, deflated, into one of the four reserves 3.
Une fois le liner rempli que la quantité de liquide à transporter, les quatre coussins de calage sont gonflés avec de l'air comprimé. Once the liner is filled with the amount of liquid to be transported, the four cushioning cushions are inflated with compressed air.
Ce gonflage à l'intérieur des réserves 3 a un double effet. En premier, lieu la pression appliquée sur les faces intérieures des réserves augmente la tension de la toile et contribue à proprement verrouiller en position les panneaux de renfort 2. Ce premier effet a une conséquence bénéfique immédiate, à savoir que la rigidité optimale de l'entier de la structure du sac est garantie, même si le liner n'est rempli de liquide qu'en partie. Mais cette interaction entre la structure du sac et les coussins donne lieu à un deuxième effet qui est d'emprisonner chaque coussin dans la seule position que lui autorise la structure du sac, respectivement l'orientation des réserves 3, à savoir une position globalement verticale. Coincé dans son corset, chacun des coussins est alors capable d'offrir une grande résistance à des forces verticales, ce que rien ne le prédestinait à faire. On pense tout particulièrement aux forces verticales générées par le poids d'un ou plusieurs autres sacs remplis et empilés au-dessus du premier. Les deux effets étant présents et en réalité interdépendants, il est difficile d'attribuer à l'un seulement un autre avantage encore, à savoir que la rigidité optimale de la structure du sac et sa résistance plus grande à la compression verticale ne sont pas compromises dans l'hypothèse où un liner endommagé laisserait échapper son contenu. La stabilité et la rigidité du sac sont certes meilleurs lorsque le liner est rempli de liquide au moins en partie, mais le seuil fonctionnel permettant l'empilage de plusieurs sacs est atteint grâce au procédé selon l'invention même si le liner est vide. This inflation inside reserves 3 has a double effect. First, the pressure applied to the inner faces of the reserves increases the tension of the fabric and contributes to properly locking in position the reinforcing panels 2. This first effect has an immediate beneficial consequence, namely that the optimal rigidity of the The entire structure of the bag is guaranteed, even if the liner is only partly filled with liquid. But this interaction between the structure of the bag and the cushions gives rise to a second effect that is to imprison each cushion in the only position that authorizes the structure of the bag, respectively the orientation of the reserves 3, namely a generally vertical position. Stuck in his corset, each cushion is then able to offer great resistance to vertical forces, which nothing predestined to do. One thinks particularly of the vertical forces generated by the weight of one or more other bags filled and stacked above the first one. Since both effects are present and in fact interdependent, it is difficult to attribute to one another yet another advantage, namely that the optimal rigidity of the bag structure and its greater resistance to vertical compression are not compromised. in the event that a damaged liner would leak its contents. The stability and rigidity of the bag are certainly better when the liner is filled with liquid at least in part, but the functional threshold for stacking several bags is achieved by the method according to the invention even if the liner is empty.
On peut imaginer, pour n'avoir à appliquer le procédé qu'une fois pour chaque sac, de solidariser de façon permanente ou non, les coussins gonflables dans les réserves du sac et de les y maintenir au fil des gonflages et dégonflages au moyen par exemple d'une dragonne ou patte de maintien qui empêche le coussin une fois dégonflé de sortir de sa réserve. It is conceivable, for not having to apply the method once for each bag, to permanently or permanently fasten the airbags in the reserves of the bag and keep them there during inflation and deflation by means of example of a hand strap or lug that prevents the cushion once deflated out of his reserve.
Les avantages issus de l'application du procédé selon l'invention s'expriment d'une part en un gain lors du trajet allant du lieu de remplissage à la The advantages resulting from the application of the method according to the invention are expressed on the one hand in a gain during the journey from the filling location to the
destination de livraison et d'autre part lors du trajet inverse. delivery destination and secondly during the reverse journey.
Lors du premier trajet, on a la possibilité, sans aucune augmentation de poids, celui des coussins étant insignifiant, d'empiler des sacs remplis les uns sur les autres et aussi bien sûr d'entreposer d'autres charges au-dessus d'un ou plusieurs sacs empilés. Lors du deuxième trajet, le coussin dégonflé représente un encombrement insignifiant à cette échelle, et un poids toujours quasi nul comme on l'a dit. During the first trip, we have the possibility, without any increase of weight, that of the cushions being insignificant, to stack filled bags on each other and also of course to store other charges over a or several bags stacked. During the second journey, the deflated cushion represents an insignificant space on this scale, and a weight that is still almost zero, as has been said.
Enfin, le prix d'un coussin de la sorte choisie est quasi nul aussi, et ne renchérit donc nullement les coûts de transport, alors que son emploi judicieux selon l'invention permet des économies substantielles en termes de poids et de volume transporté. Finally, the price of a cushion of the kind chosen is almost zero, and therefore does not increase the cost of transportation, while its judicious use according to the invention allows substantial savings in terms of weight and volume transported.
