Description

Tte present iin^ehtlor? relates tó. a method for temporarily increasing tm resistance to vertical compression of a bag for transparing and pairing liquid or quash liquid substances,: lit also: :relates to a bag resulting from the Implémentation of fie method.

The: Indastlabscale transport of liqyfcl and qyasi4quid substances,: In paiicyfar írói juice concentrates, for example, is a signileant pranoh of worlds trade.. In; after to transport each: substances, tie %si idea that comes to mind is to piste them In rigid: oantalaere such as tanks with matai or plastic walls

However, such rigid aoriainera have a major drawback, which is that they occupy the same amount of space when they era empty as when they are tot Transporting empty containers aver eery long distances to return them: to the fling point is economically and ecologically absurd. That is why preference is logically given, when they are available, to flexible containers that can be deployed for fling or, on the: contrary, folded up to occupy minimal space during the return trip to the fling location.

Such a flexible container Is in particular known from document WO 97/207ST which corresponds to the preamble of claim; 1.

Pacomért W0 2Ö09/D10S28 Ä2. briefly describes ah outer snclbsure: formed fern assembled bois of Oabyes assembled: so as broadly speaking: to form a roughly cubic bag m which a second endlosere, a liter, is placed, designed to be filled with & ligáid «r quasi-liquid substance. The four sides of the outer enclosure are made from doublé canvas and compadmentalsed so as to be able to receive reinforcing plates, the rcur vertical edges of the bag forming the outer enclosure are separated from the liner by strips of canvas sewn vertically parallel to said edges, so as to combat the tendency of the bag once fled to curve outwardly under the pressure from the liquid it contains.

The trade of liquid or geaséliquid: substances:, and In. particular of fruit juice concentrates:, is special In ínat the quantity of liquid actually transportée in a oontamwi rarely depends onfbe maximum Inner volume of the cddtaiiner, Thé container is not to the brim; it is lied based on tbe cider to be fulfilled őribe volume of liquid svailaoe ;0 the lamlc to tes emptied. For this reason, the majority of containers (flexible or neb travel only partially Usd:, and: eel lied to, full capacity,

Rigid oentapers have drawbacks,, which have been: mwBtotwák hut they have one advantage over flexible containers::: even: whan only partially full, they cap: tea partially superimposed* stacked m top of one another two or three high..

Packing flexible containers, particularly when they ere only partially filled. Is therefore problematic, which has been resolved to date by the use of wooden crates In which the flexible containers are deposited for transport Given that the weight of such a crate can reach 10S kg for each container there would be significant savings achieved If they could be eliminated.

The present insertion átü. to temporaoiy increase the resistance to vertical compression of a bag for transporting and holding itquid and; semyguid substances, so as to allow theta to he stacked and; thus eliminate the need to use craies for that purpose: alone.

To lhat end, the present Invention proposes a method: accenting to claim t The aim of the present invention is to propose a Dag according to claim 4.

According to a first embodiment, the bag is generally cubic and comprises receptacles in each: of Its comers,. The bag can include: four reæpfacies, one In each corner of the bag;.

According; to one embodiment, tour cushions are chosen for each bag.

According to one embodiment, at least one: wedging bag per receptacle is inserted.

According to one embodiment, the wedging cushions comprise two films, for example polyethylene, welded to one another, and; an iniistion/deiation valve

The following description retem to the drawing, in which figure 1 diagrammatical!? shows a partially exploded perspective; view illustrating the appiicahdh of the method according to the invention. in figure t, a bag is shown for transporting; and; holding; ilpui W dussHIgteld: substances according; to the teaching; of docume nt WO 20081818828,

One thus recognises the bag 1, the four sides of which are made from a double canvas. Each side of thé bag includes three sections delimited by two vertical seams, fand] one: nan: see a reinforcing panel 2, introduced between Ida two canvas paris of each of the three sections.

Qm cm see that the fear comers of the Peg bave receptacles 3:,. forming triangular rhombs, and that the upper mouth .of these fear receptacles Is tee and oof dosed.

The space formed by the four receptacles can he occupied by any members designed to mate it: possible to stack the begs. It should m borne in mind that the entire inside of the: bag, Its central pert, is occupied by a liner deslped to be lied with the liquid to be transported.

One could certainly consider introducing additional frames Into the receptacles, for example billets with an appropriate sise, but It Is much more elegant not to make the entire transported weight heavier while obtaining the expected result.

Yet In the transport field. In particular port: transport, inflatable wedging cushions (dunnage bags) are used to stabilize loads for example inside large ISO containers measuring 40 feet. When these cushions are deflated, they resemble a fiat, empty pillowcase. These cushions are produced using two polyethylene films welded to one another over their shire perimeter and are provided with an inflation and deflation valve. When they are inflated w|h compressed air, these cushions look Ike large, particularly plump pillows.

Various sizes and shapes of such inflatable cushions are commercially avaitable,

These cushions are very strong, and the Interna! pressure may be high enough for them to be hard as stone.

In alt oases of normal application,: these cushions are used to laterally occupy space between two loads, so as to separate them from one another along a horizontéi axis determined bythe center of lie two faces of the cushion. However, on fha contrary,: nothing encourages: using the properties of those cushions along a dlferentexss,

Yet that idea; Is the key to the inventive method.

Figure 1 snows that a wedging cushion 4 has been chosen whose measurements correspond to those of the reoeplecfes 1 In terms of height and width. The cushion is also chosen based on the position of its inflation valve 5, which should ideally be close to a longitudinal end of the cushion.

Four cushions are selected fer each bag and: each of there is Inserted, deflated ; into one of the four receptacles 3.

Once the liner is lied: with the quantity of liquid to be transported, the four wedging cushions are inflated with compressed: air.

This inflation inside fee mœpfacles 3 has a dual effect. First, the pressure applied on the inner faces of the receptacles: increases the tension of the canvas and cenfhbutes to cleanly iooing the reinforcing panels 2 In position. This first effect has m immediate beneficial consequence, i;e >; that: the: optimál hgidtty of the entire structure of the Pag it guaraptasst even If fee liner is only partly filled win liquid. However, this Interaction; between fee sfmeture of the bag and the cushions leads to a seccne effect, namely capturing, each cushion ih the only position allowed far if by the structure or toe dag:, the diehtsflon of the receptacles 3, respectively. la,. a. globally vertical position, dammed: in Is süpped, each of fee cushions Is than capable of offering considerable resMancs to vertical forces, which nclhlhg; predestined it to do, One may sa pamcuiar think about the vedical forces generated by the weight of one or mom ether begs tilled and; stacked on top of the first. The two effects being present and. ;n reality, interdependent, it is difficult to attribute a further advantage to oniy one of them, Le., that the optimal rigidity of fee sfrecture of the bag and ®§- greater resistance te vemosr compression are not compromised in fee case where a damaged Itier allows m contents to escape. The stapily and rigidity of fee bag are certainly better when fee liner is at least partially filled with liquid, but the functional threshold allowing several bags to be stacked Is reached owing to the inventive method even If fee liner Is empty..

One could consider permanently or reversibly securing; the Inflatable cushions m the receptaclee of the bag. so as only to have to apply the method once for each bag, and keeping them: there, during: the inflations and: datations, tor example using a maintaining: strap or tab that prevents the cushion from; leaving its receptacle once deflated.

The advantages resulting from fee application: of the Inventive method are reflected on the one hand by a gain during: the Journey from fee filling location: to the delivery location, and on lie other hand during the return tap.

During ths first trip. Ills possible, without mf weightloomass, to stae* filled; page on ono another and, of course, to store other loads shows one or more o? the stacked dap.

During trie second trip, the deflated cushion represents an insignificant hulk oh that scale, and a still ouashzero weight, as stated aipve.

Lastly, the price of a cushion: chosen ih dlls way is also practically null, and therefore dees net increase transport costs at all, whereas its jiidiclous use according to the iheenlon ailcwS sighlicanf sa^ihgs in terms of transported weight and relume.
