Abstract

A bulk material cargo container liner system comprises an inflatable bulk material cargo container liner which has at least one vacuum discharge tube member disposed internally within the bulk material cargo container liner and extending throughout the longitudinal extent thereof for discharging bulk cargo material outwardly from the bulk material cargo container liner, and at least one inflatable air bag component which also extends throughout the longitudinal extent of the bulk material cargo container liner and is initially disposed in a deflated state but which is adapted to be disposed in an inflated state when the bulk cargo material can no longer be evacuated under natural gravitational forces. By inflating the at least one inflatable air bag component, the angle of repose of the bulk cargo material disposed internally within the bulk material cargo container liner is effectively altered in a positive manner so as to cause the bulk cargo material to again flow toward the at least one vacuum discharge tube member whereby the bulk cargo material can be evacuated from the bulk material cargo container liner without the need for tilting the bulk material cargo container and the liner contained therein.

Description

INTERNAL CONTAINER LINING OF BULK MATERIAL LOADING. WITHOUT INCLINATION FIELD OF THE INVENTION The present invention relates generally to bulk material loading containers within which fluid-like or fluid-like loading materials, such as, for example, dry bulk chemicals, resins in powder forms, flakes, and of pelle, coffee beans, flour, grains, rice, sugar or the like, which are normally housed or contained while being shipped or transported, and more particularly to a new and improved container liner system for loading bulk material , for use in conjunction with such bulk material loading containers, wherein the new and improved bulk material loading container liner system not only enables or allows the bulk material loading container to be used as a bulk container. storage tank or silo of bulk material, but also, facilitates the unloading of the cargo of bulk material loading from the container of c bulking of bulk material in accordance with operational techniques that do not require that the bulk material loading container be moved within an inclined mode, as is normally performed or driven in accordance with loading load loading techniques of material to conventional bulk or from the PREVIOUS TECHNIQUE in order to effectively discharge the loading load of bulk material from the bulk material loading container, although on the contrary it achieves that the unloading of the loading of bulk material from the bulk material loading container as a result of the effective alteration of the resting angle of the bulk material placed inside the bulk material loading container.

BACKGROUND OF THE INVENTION Bulk material loading containers are used in a conventional manner, on different occasions, to house or contain different bulk materials similar to fluid or fluid cargo, such as, for example, dry bulk chemical agents, powdered resins, flakes and pellets, flour, coffee beans, grains, rice, sugar and the like, while the bulk cargo materials that are shipped or transported from one location to another by, for example, ship, truck, railroad and the like. Since different bulk cargo materials are shipped or transported within particular bulk material loading containers at different times, it is imperative that the bulk material loading containers are effectively cleaned so as not to contaminate bulk cargo materials that it comprises a loading load of particular bulk material with residual bulk materials that can remain inside the bulk material loading container from a loading load of bulk material previously shipped or transported. Accordingly, in order to eliminate the normally necessary cleaning of each cargo container of bulk material held after a cargo load of particular bulk material has been unloaded from a particular cargo hold of bulk material loading container , it has become conventional in the industry to employ removable liners from the bulk material loading container within the cargo holds of the bulk material loading containers where, after a cargo load of material has been delivered to In particular bulk to its destination and unloaded, the lining of bulk material loading container is simply removed from the bulk material loading container so that the loading container of bulk material is usable again, without being required a significant amount of cleaning, to transport another cargo of bulk material that you buy Commonly fluid or flowable loading material. Bulk material loading containers, which have bulk container loading liners placed thereon for shipping or transporting fluid or flowable bulk cargo materials, can be found, for example, within the Patent of the United States of America 5,657,896 which was issued on August 19, 1997 for Mafias, United States of America Patent 5,542,563 which was issued on August 6, 1996 for Matías, Patent of the United States of America 5,489,037 which was issued on February 6, 1996 for Stopper, United States Patent 5,421, 476 which was issued on June 6, 1995 for Matías, Patent of the United States of America 5,222,621 which was issued on June 29, 1993 for Matías, Patent of the United States of America 5,193,710 which was issued on March 16, 1993 for Podd, Sr. et al , United States Patent No. 5, 152,735 which was issued on October 6, 1992 for Podd, Jr. et al., Patent of the United States of America ,137,170 which was issued on August 11, 1992 to Matthias, United States of America Patent 4,884,722 which was issued on December 5, 1989 to Podd, and United States Patent 4,541, 765 which was issued on September 17, 1985 for Moore. In connection with the aforementioned use of bulk container cargo container liners within bulk material loading containers, it is noted that, conventionally, cargo container liners of bulk material are provided with a port of upper intake through which the bulk cargo material is led into the cargo container liner of bulk material, or a lower cargo port through which the bulk cargo material is discharged or evacuated out of the cargo container. Loading container lining of bulk material. When the bulk loading material is in fact going to be discharged from the loading container liner of bulk material, the discharge port is opened, and the gravitational forces will initially cause the bulk loading material to flow naturally and Automatic out through the discharge port of the container liner loading bulk material. This procedure will continue until the bulk loading material reaches or reaches its natural angle of repose, as determined along the sliding surface of the bulk loading material, at which time the different forces acting on the material of Bulk cargo will effectively be the same and opposite each other to achieve or obtain in this way a static state and will no longer flow. More particularly, for example, the gravity vector that is operating or oriented along the sliding surface of the bulk loading material, to thereby act accordingly on the bulk loading material in order to cause Normally the bulk loading material will flow naturally or automatically, it will be effectively counteracted by other vectors of force inherent to or characteristic of the bulk loading material, such as, for example, forces of conglomeration, forces of encasing, forces frictional, shear forces, and the like. The entangling or cutting forces are or can be determined, for example, by means of the size, shape and density characteristics of the bulk loading material, while the conglomeration forces are or can be determined, for example, by medium of the moisture, additive and other characteristics of the bulk loading material. Therefore it can be further appreciated that when the angle of the sliding surface of the bulk loading material, along which the bulk loading material will flow in a normal manner, is equal to or less than the equilibrium angle above mentioned, or in other words, the angle of repose of the bulk loading material, the bulk loading material will remain static and will not flow due to the fact that the force vector of gravity that operates or is oriented along the sliding surface of the bulk loading material is in fact sufficiently counteracted by the other aforementioned force vectors that operate or are oriented in a similar manner along the sliding surface of the bulk loading material. Conversely, when the angle of the sliding surface of the bulk loading material, along which the bulk loading material normally flows, is greater than the equilibrium angle or the above-mentioned resting angle of the material For bulk loading, the bulk loading material will become dynamic and in fact will flow due to the fact that the vector of gravity force that operates or is oriented along the sliding surface of the bulk loading material is now higher which exceeds or exceeds the other aforementioned force vectors which operate or are oriented in a similar manner along the sliding surface of the bulk loading material. Conventionally, the most common way by which the aforementioned fluidity characteristics of the bulk cargo material can be affected, altered or adjusted, is to cause the bulk cargo container to undergo a tilt operation by means of from which, for example, the front end of the bulk material loading container is raised to a level of elevation that is greater than the rear or rear of the bulk material loading container. More particularly, when a particular bulk material loading container, which transports a particular bulk loading material, undergoes a predetermined amount or degree of inclination, the particular bulk loading material will begin to flow again under the influence. of gravity, and consequently can be conducted to the unloading port of the bulk material loading container, due to the sliding surface angle of the bulk loading material, or in other words, the angle of inclination or declined, is now greater than or exceeds the angle of repose of the bulk loading material so that the gravity vector, which operates or is oriented along the sliding surface of the bulk loading material, has been increased in a manner effective to be greater than, exceed or exceed the vectors of force of encasing, frictional, shear, and conglomeration n above. However, it has been experienced that the implementation of said tilting operations of the bulk material loading container can not always be achieved easily or quickly, in particular in an effective manner at a cost. Normally, for example, in order to understand the economically viable bulk transportation, delivery and distribution systems of bulk material, the systems comprise an operational integration of the transportation facilities of the bulk material loading container, such as example, hopper wagons or a fleet of trucks, trailer tractors for bulk material loading containers, high-water freighters for bulk material loading containers, and the like. In addition, the bulk material loading container tilting device or mechanisms are conveniently or feasibly placed in predetermined locations adjacent to or near the bulk container shipping facilities for operatively handling containers of bulk material. hopper wagons, tow trucks and aforementioned vessels to unload or unload cargoes of bulk material transported in this manner. further, a silo or other similar storage facilities of bulk material are conveniently or feasibly located or located in predetermined locations with respect to the transportation facilities and to be capable of storing bulk cargoes landed in preparation. for, or in conjunction with, the distribution of some bulk material to the end users. Unfortunately, as can be easily appreciated, the construction and operation of said integrated transportation, handling and distribution system is relatively expensive. Consequently, it is only comically viable for these integrated transport, delivery and distribution systems to be constructed and operated by relatively large companies located mainly in highly industrialized nations. Therefore, it is further appreciated that relatively medium and small companies are not able to compete economically viable with large companies in view of the fact that these medium and small companies do not have access to, or the economic resources to build and operate , the integrated facilities of transportation and handling of container of bulk material loading mentioned above, or storage facilities and distribution of bulk material. In the best case, if such relatively medium or small companies wish to engage in the transportation, handling and distribution of bulk cargo, and try to compete with relatively large companies, they are often forced to rent the necessary services or facilities with relatively large companies which, again, is not economically advantageous. However, if a bulk material loading container system could be developed where the tilt-type apparatus or systems are no longer needed to unload or unload the bulk cargo from the material loading containers to bulk, or in addition, if the apparatus or systems could be similarly developed where the auxiliary silo-type storage facilities are no longer needed to store and distribute the bulk material loading charges from the bulk material loading containers, then the relatively medium and small companies could enjoy the economic advantages derived from the systems of transportation, handling and distribution of loading of bulk material. Relatively medium and small companies could therefore compete economically viable with relatively large companies. There is therefore a need in the art for a new improved bulk material loading container liner system, for use within bulk material loading containers, where the tilt type apparatus is no longer necessary for unloading or unloading cargoes of bulk material from bulk material loading containers, and in addition, a new and improved container liner system for loading bulk material, for use within bulk material loading containers , where auxiliary silo-type installations are no longer needed to store and distribute loading loads of bulk material from the bulk material loading containers, so that medium and small companies can enjoy the economic benefits that derive from them. of the systems of transportation, handling and distribution of loading of bulk material so that the companies relatively medium and small as can in fact viably compete economically with the relatively large companies.

BRIEF DESCRIPTION OF THE INVENTION The aforementioned need is solved in accordance with the teachings and principles of the present invention as a result of the provision of a new and improved container liner system for bulk material loading, for use within shipping container containers. Bulk material, where, according to a primary modality of the new and improved bulk container loading liner system, an inflatable cargo container bulk material liner has a pair of air bags or inflatable bins connected in an integral way to it or associated with it. The airbags or inflatable compartments may be located outside of, or within, the bulk container loading container liner, and may comprise various cross-sectional configurations, such as, for example, being substantially triangular in cross section or, alternatively, comprising a plurality of inflatable airbags having substantially circular cross-sectional configurations although they are connected together in an integral manner so that the overall cross-sectional configuration is substantially triangular. In either case, the air bag assemblies or inflatable compartment will have substantially straight triangular configurations when placed in their inflated states so that the hypotenuse portions of the inflatable air bags or compartments will be inclined with respect to the portion to the portion of bottom or bottom surface of cargo container liner of bulk material. The bags of inflatable material are preferably disposed, for example, within the longitudinally extending, laterally spaced, lower corner regions, positioned opposite of the bulk container loading container liner, and may be operatively associated with an assembly. of vacuum tube that may be located along the longitudinal center line of the bulk container loading container liner. In this way, when the airbags or compartments are inflated, the angled hypotenuse portions of the air pockets or compartments will act effectively on the bulk loading material placed within the cargo container liner of bulk material for effectively altering the angle of inclination of the sliding surface of the bulk loading material so that the sliding surface of the bulk loading material effectively obtains an angle that is greater than the resting angle of the loading material in bulk so that the bulk loading material can once again flow dynamically and be discharged from the bulk container loading liner through the vacuum tube assembly.

Bulk cargo from the inner portion of the cargo container liner of bulk material; and FIGURE 5 is a perspective view of a first alternative embodiment of a vacuum discharge tube assembly, which can be used within one of the bulk material loading container liners as desired, wherein the The vacuum discharge tube assembly has a substantially circular cross-sectional configuration and is provided internally with a helical spring member in order to effectively prevent internal collapse of the vacuum discharge tube assembly as well as to facilitate the preservation of the Tubular configuration of the vacuum discharge tube assembly in spite of bending or winding thereof during, for example, storage or transportation of the vacuum discharge tube assembly prior to installation thereof into the cargo container liner of bulk material.

DETAILED DESCRIPTION THE PREFERRED MODALITY As mentioned so far, in order to unload or unload a cargo load of bulk material or contents from a bulk container cargo liner, the cargo container of bulk material, inside which is placed the loading container liner of bulk material, normally needs to be tilted, although, in accordance with the teachings and principles of the present invention, the need to tilt the bulk container of cargo, to unload or unload the cargo Loading of bulk material or contents thereof, is eliminated or, becomes unnecessary. More particularly, if the lifting of the material loading container is to be eliminated, the means must be provided in any way in order to cause the loading load of bulk or contained material to undergo its movement of requirement or fluidity towards the port of unloading or unloading to be able to be unloaded or unloaded from the container liner of bulk material loading. According to the particular principles and teachings of the present invention, the bulk container loading container liner has integrally incorporated therein at least one vacuum discharge tube assembly and a plurality of bag components. of inflatable air wherein the inflatable airbag components are adapted to be inflated by means of, for example, suitable valve structures, not shown, which are adapted to be fluidly connected to means of inflation control and deflation suitable, which are also not shown, to operatively control the movement of the bulk loading material towards the vacuum discharge tube assemblies. Referring now to the drawings, and more particularly to FIGURE 1 thereof, a first embodiment of a new and improved inflatable air bag component which has been constructed in accordance with the principles and teachings of the present invention , and which is adapted to be used within a corner region of a new namle and improved container liner of bulk material that has also been constructed in accordance with the principles and teachings of the present invention, to facilitate the unloading or unloading of bulk cargo materials from the bulk container loading container liner and the bulk material loading container without requiring any tipping operation of the bulk material loading container is described and indicated generally by the reference number 10. More particularly, it is noted that the air bag component inflatable 10 new and improved has a substantially triangular straight configuration. In accordance with the intended use of this particular embodiment of the inflatable air bag component 10, the inflatable air bag component 10 is adapted to be placed internally within the bulk cargo container liner 12 which has the configuration of a rectangular parallelepiped, as is conventionally known, so that the vertically oriented leg portion 14 of the inflatable air bag component 10 is adapted to be positioned along a vertical side wall 16 of the cargo container liner of bulk material 12, while the horizontally oriented leg portion 18 of the inflatable airbag component 10 is adapted to be positioned along the bottom wall or floor portion 20 of the cargo container liner of bulk material 12. In this way, it can be easily appreciated, in turn, that the hypotenuse portion 22 of the air bag component i The inflatable air bag component 10 will be positioned at a predetermined inclined angle within the inner portion of the bulk material loading container liner 12. It is further appreciated that the inflatable air bag component 10 is adapted to extend throughout the entire extension. longitudinal of the cargo container liner of bulk material 12. AccordinglyWhen the inflatable air bag component 10 is placed in its inflated state, the inclined hypotenuse portion 22 of the inflatable air bag component 10 will effectively raise the bulk loading material placed inside the bag. of the bulk material loading container liner 12, from the side wall and the corner regions of the bulk material loading container liner 12 to an axially central region of the bulk container 12 cargo container liner. Inverse mode, when the inflatable air bag component 10 is placed in its deflated state, ie, before inflation for its intended use, the hypotenuse portion 22 of the inflatable air bag component 10 will effectively collapse within of the left corner region of the bulk material loading container liner 12 as defined at the intersection of the vertical side wall portion 16 of the liner d e loading container of bulk material 12 and the horizontal bottom wall or floor portion 20 of the loading container liner of bulk material 12. As can be readily appreciated from well-known principles and teachings of flat geometry, the linear extension of the hypotenuse portion 22 of the inflatable air bag component 10 is smaller than the combined linear extensions of the vertically oriented leg portion 14 of the inflatable air bag component 10 and the horizontally oriented leg portion 18 of the component of inflatable air bag 10. Therefore, it is noted that in order to allow or facilitate the aforementioned internal collapse of the inflatable air bag component 10 so that it can in fact be placed within the equine region of the inflatable air bag 10. bulk material loading container liner 12 when the inflatable air bag component 10 is going to be placed in its fully disinfected state The regions of the vertically oriented leg portion 14 of the inflatable air bag component 10 and the horizontally oriented leg portion 18 of the inflatable air bag component 10 are located away from the corner region of the bag component. inflatable air are not actually secured to the vertical side wall 16 of the bulk material loading container liner 12 or to the bottom wall or floor portion 20 of the bulk material loading container liner 12. It is noted that the bag component inflatable air 10 has a plurality of substantially triangular straight, axially spaced apart folds 24 positioned internally within the inflatable air bag component 10 not only to provide internal support within the inflatable air bag component 10 throughout the entire axial extension thereof, but in addition, the plurality of folds 24 effectively divides the entire inner region of the inflatable airbag component 10 into a plurality of axially spaced cells 26. The cells 26 may comprise fluidly separated compartments to be inflated separately through appropriate means, not shown or, alternatively, the cells 26 can be fluidly connected to each other in order to be inflated simultaneously through suitable means, which are also not shown. The prior use of one or more of the inflatable air bag components within the liner of cargo containers of bulk material can be best appreciated with reference to the additional to FIGURE 2. More particularly, as illustrated within FIGURE 2, a bulk material loading container liner 112 is positioned internally within a bulk material loading container 128, and it is noted that the bulk material loading container liner 112 has a pair of components of inflatable air bag 110, each of which is substantially similar to the inflatable air bag component 10 as described in FIGURE 1, positioned internally within the laterally separated corner regions, positioned opposite of the cargo container liner of bulk material 112. In this way, when the inflatable airbag components 110 are inflated, as illustrated, the bulk loading material, with located within the bulk material loading container liner 112, it will be moved towards the longitudinal center line region of the bulk material loading container liner 112 to be discharged by means of a discharge pipe assembly to I v Acid, or axially oriented, individual 1 30 that is located along the longitudinal center line region of bulk material loading container liner 112 and which is fluidly connected to a suitable vacuum source , not shown. Further continuing, as mentioned hereinabove, and as is well known in the art and in the industry, the bulk loading material internally positioned within the bulk container loading container liner is adapted to be discharged and ejected by means of a vacuum source, not shown, which is operatively and fluidly connected to the rear end portions of the vacuum discharge tube assemblies that are adapted to be pumped out through the rear end wall member of the bulk container loading container liner. As can be seen, therefore, due to the well-known phenomena or principles of pressure differential or pressure drop, it is therefore possible to effectively print a higher level of vacuum or suction force on that portion of the pressure material. Bulk cargo that is placed in the vicinity of the rear end wall member of the bulk cargo container liner in the position to which the bulk loading material that is positioned within the vicinity of the extreme wall member is placed. Front of container liner loading bulk material. Consequently, if it is determined that only a relatively low or insufficient amount of vacuum or suction force can be imposed on that portion of the bulk loading material that is placed within the vicinity of the front end wall member of the material loading container liner in bulk so that the flat portion of the bulk cargo material that is placed within the vicinity of the front end wall member of the bulk container cargo liner can not necessarily be unloaded or unloaded sufficiently or completely, the structural incorporation of means within the vacuum discharge tube assemblies that can effectively alter the vacuum or suction force levels that may be generated through the longitudinal extension of the discharge pipe assemblies may be desired. vacuum between the rear and front wall members of the bulk material loading container liner so that, for example, higher levels of vacuum or suction force can be generated within the vicinity of the front end wall member of the Loading container lining of bulk material. More particularly, as described within FIGURE 3, the vacuum discharge tube assembly may comprise a plurality of longitudinally aligned sections 2130-1, 2130-2, and it is observed that first means, to alter the effective levels of vacuum or suction force that can be printed on the bulk loading material through the longitudinal extension of the bulk container loading container liner, resides in the provision of a pair of strips or plates with openings 2115, only one of which is actually illustrated, within each of the vacuum discharge tube assembly sections 2130-1, 2130-2 so that the strips or plates with openings 2115 are movably mounted respectively on the internal portion of each of the sections of vacuum tube assembly 2130-1, 2130-2 between positions EXTENDED and RETRAIDED. Each of the strips or plates 2115 is provided with a plurality of longitudinally or axially spaced apertures 2117, and consequently, depending on the relative arrangement of the strips or plates 2115 with respect to the vacuum discharge tube assembly sections 2130 -1, 2130-2, the openings 2117 defined within the strips or plates 2115 may be aligned with respect to, for example, the openings 2142 defined within the peripheral side portions of a particular discharge tube assembly sections. vacuum, as described, for example, in connection with the vacuum discharge tube assembly section 2130-2, or alternatively, the openings 2117 defined within the strips or plates 2115 that may be misaligned with respect to a, for example, openings 2142 defined within the peripheral side portions of a particular vacuum tube assembly assembly sections, as described by example, in connection with the vacuum discharge tube assembly section 2130-1. It can be appreciated therefore that when the openings 2117 defined within a particular of the strips or plates 2115 are misaligned with respect to the openings 2142 defined within a particular of vacuum discharge tube assembly sections, as for example, in relation to the strip or plate 2115 and the vacuum discharge tube assembly section 2130-1, the air flow from the inner portion of the bulk material loading container liner 2112 and through the openings 2142 defined within the vacuum discharge tube assembly section 2130-1 is effectively blocked. Conversely, when the openings 2117 defined within a particular of the strips or plates 2115 are aligned with respect to the openings 2142 defined within a particular of the vacuum discharge tube assembly sections, as for example, the vacuum discharge tube assembly assembly 2130-2, the air flow from the inner portion of the bulk material loading container liner 2112 and through the openings 2142 defined within the discharge tube assembly section to the Vacuum 2130-2 is allowed effectively. Accordingly, it is possible to generate different levels of vacuum or suction force, and be applied on different regions of the bulk loading material placed within the bulk container loading container liner 2112 to thereby facilitate and ensure discharge and escape of the bulk loading material from all longitudinal or axial regions of bulk material loading container liner 2112. It is finally observed in connection with this adjustment system that the strips or plates 2115, 2115 positioned within some of the adjacent vacuum discharge tube assembly sections 2130-1, 2130-2 can be interconnected by suitable means, such as, for example, a slot and belt assembly 2119. In this way, the strips or plates 2115, 2115 can be moved to or placed in, various longitudinal or axial positions as desired or required. Referring now to FIGURE 4, it is noted that second means, to alter the effective levels of vacuum force or suction that can be printed on the bulk loading material through the longitudinal extension of the cargo container liner. Bulk material, reside in the provision of a sleeve member with openings 2215 within each of the vacuum discharge tube assembly sections 2230 so that the aperture sleeve member 2215 is movably mounted respectively within the inner portion of each of the vacuum discharge tube assembly sections 2230 between EXTENDED and RETRACED positions. The sleeve members 2215 are similar to the strips or plates 2115 mentioned above in that each of the sleeves 2215 is provided with two sets of longitudinally or axially spaced apertures 2217, only one assembly being visible, and consequently, depending on the relative arrangement of the sleeves 2215 with respect to the vacuum discharge tube assembly sections 2230, the openings 2217 defined within the sleeves 2215 may be aligned with respect to, for example, the openings 2240,2242 defined within the portions peripheral sides of a particular vacuum tube assembly 2230, or alternatively, openings 2117 defined within the sleeves 2215 may be misaligned with respect to, for example, the openings 2240, 2242 defined within the peripheral side portions of a particular of the vacuum discharge tube assembly sections 2230. It can be seen therefore that when the openings 2217 defined within a particular one of the sleeves 2215 are misaligned with respect to to the openings 2240, 2242 defined within a particular of the vacuum discharge tube assembly sections 2230, the air flow from the inner portion of the bulk material loading container liner 2212 and through the openings 2240, 2242 defined within the vacuum discharge tube assembly section 2230 is effectively blocked. Conversely, when the openings 2217 defined within a particular one of the sleeves 2215 are aligned with respect to the openings 2240, 2242 defined within a particular of the vacuum discharge tube assembly sections 2230, the air flow from the inner portion of the bulk material loading container liner 2212 and through the openings 2240, 2242 defined within the vacuum discharge tube assembly section 2230 is effectively enabled. Accordingly, again, it is possible to generate different levels of vacuum or suction force and print them on different regions of the bulk loading material placed within the bulk container loading container liner 2212 to facilitate and secure this The discharge and escape of the bulk loading material from all longitudinal or axial regions of the loading container liner of bulk material 2212 is observed. It is also observed, in relation to this adjustment system, that the diametral size of the openings 2217 , 2240, 2242, which are respectively defined within the sleeve member 2215 and the vacuum discharge tube assembly section 2230, can be varied so as to easily allow, for example, the partial closing of the openings 2217, 2240, 2242 and the partial blockage of air flow through them. In addition, the distance or distance defined between some successive openings 2217, 2240, 2242 can be varied in the same way. Such variations allow different levels of vacuum force to be obtained or from within the vacuum discharge tube assembly sections 2230, and such variations may also be incorporated within the strips or plates 2115 as described in connection with the embodiment illustrated within FIGURE 3.. It is finally observed that, in relation to the different bulk materials that are transported within the cargo container lining of bulk materials, it is sometimes easy to unload and eject particular types of materials to bulk cargo in comparison with other types of materials to load it. For example, in connection with the placement of relatively thick bulk cargo materials, such as, for example, pellets, tablets, or the like, within the cargo container liner of bulk material, a substantially large volume of air is present in a effective within the entire load of bulk cargo material in view of the fact that air can permeate all spaces or gaps defined between some adjacent or spliced individual units, i.e. pellets, tablets, or the like, which comprise the Loading of bulk loading material. Accordingly, when said bulk loading material is to be discharged and expelled by means of the vacuum discharge tube assembly, the air present within the entire bulk loading material charge is able to flow and enter effectively. inside and through the bulk loading material to deh transport, load and release the bulk cargo material out of the bulk container loading liner. On the other hand, when the bulk loading material comprises relatively fine material, such as, for example, powdered materials or the like, there is a relatively small volume of air present within the entire loading of bulk loading material in view of the fact that minute particles , which comprise said powder-type bulk loading material, are in fact packed together so densely, that the substantially dimensioned spaces or interstices, within which air can permeate easily, simply do not exist. Therefore, when said bulk cargo materials are to be unloaded and expelled from the cargo container liner of bulk material, the vacuum or suction forces can not develop the necessary air flow within the bulk cargo material. to enter the bulk loading material along said flow. Accordingly, in order to rectify the aforementioned deficiency in connection with the discharge and ejection of bulk powder-type loading materials, a vertically oriented regulating column 2221, as shown in FIGURE 4, is structurally and electrically connected. fluid to the most anterior end portion of the most anterior section of the vacuum discharge tube assembly 2230. The upper end portion 2223 of the vertically oriented regulating column 2221 is adapted to be positioned on the upper level portion of the loading material bulk positioned within the bulk material loading container liner 2212, and thus, the ambient air is always effectively present within the front end portion of the most anterior section of the vacuum discharge tube assembly 2230 for Effectively exercise atmospheric pressure on any bulk cargo material present within and the entire vacuum discharge tube assembly 2230. Such atmospheric air cooperates fluidly with the vacuum or suction forces operating at the rear end of the vacuum discharge tube assembly 2230, and consequently, even the Bulk type powder loading can be discharged and ejected from bulk material loading container liner 2212. Continuing further, and in connection with the actual manufacture of any of the vacuum discharge tube assemblies described above , one modality, mode, or additional technique is considered in accordance with the principles and teachings of the present invention and is described within FIGURE 5. For example, as described within FIGURE 5, it is noted that one of the sections of vacuum discharge tube assembly 2330 has a helical spring member 2325 which is internally disposed thereto and which extends through t all longitudinal or axial extension of each vacuum discharge tube assembly section 2330. In this manner, coil spring members 2325 effectively assist in preventing internal collapse of any of the vacuum discharge tube assembly sections. 2330, not only when the vacuum discharge tube assembly sections 2330 are placed within the bulk container loading container liner, and when the bulk container loading container liner has bulk loading material placed in the container. the same, but also, the arrangement or presence of the coil spring members 2325 internally within the vacuum discharge tube assembly sections 2330 effectively prevent internal collapse thereof while the assembly sections of vacuum discharge tube 2330 are flexed, flexed or rolled, imilar, d urante, for example, handling or storage of my smas Having described the various structures mentioned above that comprise the inflatable airbag component, the vacuum discharge tube assemblies, and the general bulk container loading liner system with which the inflatable air bag components and the vacuum discharge tube assemblies to be used, are will now give a brief description of the operation of the bulk container loading liner system, having the inflatable air bag components and the vacuum discharge tube assemblies associated therewith. It will be appreciated, for example, that when a loading load of bulk material is shipped or loaded initially into one of the lining linings of bulk material loading container, the vacuum discharge tube assemblies will be placed in their positions internally within the inflated liner of bulk material loading container, although the inflatable air bag components will be placed in their deflated states so that they allow a full and full shipment of cargo of bulk material to be loaded or shipped within the container liner of bulk material loading. Subsequently, when the loading of bulk material is going to be unloaded, disembarked and ejected from any container liner of bulk materials, each of the vacuum discharge tube assemblies will be fluidly connected to the container. the vacuum source, not shown, will activate the vacuum source, and the bulk loading material will flow naturally to each of the vacuum discharge tube assemblies. However, at a particular time point, the natural flow of the bulk loading material towards the vacuum discharge tube assemblies will end according to the aforementioned gravitational forces acting on the bulk loading material, ie when the angle of repose of the bulk loading material reaches a particular point or level. At this point of time, the inflatable airbag component can be progressively inflated to positively alter or improve the angle of repose of the bulk cargo material whereby it can flow back to the tube assemblies of vacuum discharge to be expelled from the lining of bulk material loading container. Therefore, it can be seen that according to the different principles and teachings of the present invention, a plurality of new and improved bulk container liner systems have been described wherein each of the systems comprises an inflatable liner of bulk material loading container having at least one inflatable air bag component, and at least one vacuum discharge tube assembly operatively associated with the component. When the inflatable air bag components are inflated progressively to assist in the unloading, unloading and ejection of the bulk cargo material from the back of the cargo container liner of bulk material, after it has been unloaded, disembarked and ejected a portion of the bulk loading material in accordance with natural gravitational forces whereby the surface of the bulk loading material has already reached a particular angle of repose, the angle of repose of the surface of the bulk loading material will be positively readjusted so that the remaining portion of the bulk cargo can be unloaded, unloaded and ejected without the need for any inclination of the bulk material loading container and bulk cargo container liner placed in the cargo container. same.

Obviously many variations and modifications of the present invention are possible in light of the above teachings. It is therefore understood that within the scope of the appended claims, the present invention may be practiced in a manner different from that specifically described herein.
