Description
i302315 This invention relates to an inner bag for a container for use in transportation.
Containers have been widely used on ships and trains for the bulk transportation of goods such as corn and other food, raw materials for industries, industrial goods and other loads. If these goods are directly loaded into the containers, the inside surfaces of the containers will most likely be contaminated by the goods. The smell or odor of the goods often remains in the containers for a considerable period of time and thus is detrimental to goods subsequently loaded into the containers for transportation. This is, of course, a disadvantage and to deal with this problem an inner goods bag is often located in a container and the goods are loaded into it but do not come directly in contact with the walls of the container.
Unfortunately during the transportation of goods in an inner bag in a container, dew is often deposited on the inner walls of the container and the surfaces of the inner bag. Moreover, rain water or sea water may enter the container and be deposited on its outer surfaces, particularly an upper surface of the inner bag, in the form of small pools or droplets and a pool may also form on the bottom surface of the container.
When inner bags were previously used, it was found that when the inner b~g was tilted into a dump-up position so as to discharge the goods stored within it, the water flowed along the outer surfaces of the inner bag, or the bottom surface of the container, to the discharge outlet, and thus goods such as barleycorns for beer or chemical medicines which were being discharged through the outlet became wet due to being splashed with water. Furthermore, water often entered the inner bag through its stitched seams and this water resulted in contamination of the goods. When the goods transported were metal goods such as machinery, the goods were often rusted due to water entering the inner bag.
It is a principal object of the present invention to provide an inner bag for a container wherein the above-mentioned disadvantages of the prior art bag are obviated or substantially reduced and contamination by rain water, dewing or the like is reduced.
.i, ~302315 Accordingly, the present invention provides an inner bag for a container comprising a top surface, a bottom surface, a rear surface, side surfaces and a front surface to form a substantial hexahedron and having fastening members for fastening said inner bag to inner walls of the container, said inner bag including one or more waterproof members provided on at least part of the outer surfaces of said inner bag.
In a preferred embodiment of the invention, the waterproof member is made of an unwoven fabric.
Waterproof members are preferably provided on the front and rear portions of the upper surface in the form of belts. The waterproof members may extend from an edge between the upper surface and one side surface to an edge between the upper surface and the other side surface.
In a further embodiment of the invention, the waterproof members are further provided on front and rear portions of the bottom surface in the form of belts, and particularly the waterproof members extend from an edge between the bottom surface and one side surface to an edge between the bottom surface and the other side surface.
With the inner bag constructed as above described, the waterproof members provided on part, parts or all of the outer surfaces of the inner bag absorb the water when rain water or sea water enters the container or dew is deposited on the outer surfaces of the inner bag to prevent the water from entering the inner bag, thereby preventing goods from being contaminated by the water.
The waterproof members absorb the water accumulated on the outer surfaces of the inner bag to prevent the goods from being contaminated by the water flowing along the outer surfaces of the inner bag whilst the goods are being discharged from the inner bag in a dump-up position.
BRIEF DESCRIPTION OF THE DRAWINGS
In order that the invention may be more clearly understood, preferred embodiments will now be described, by way of example, with reference to the accompanying drawings in which:-,~
Fig. 1 is a schematic perspective view illustratingan inner bag for a container of the prior art; and Fig. 2 is a schematic perspective view illustrating one embodiment of an inner bag for a container according to the present invention.
DETAILED DE~;CRIPTION OF PREE'E:RRED E:M~ODI~!ENTS
The attached drawings are sufficiently schematic to an extent that the embodiments of the invention can be substantially understood and therefore shapes, dimensions and positional relationships between the respective components of the invention are not limited to those shown in the drawing.
One example of a prior inner bag as shown in Japanese Laid-open Patent Application No. 49-105,686 will be explained now by referring to Fig. 1.
Fig. 1 is a schematic perspective view illustrating the prior inner bag for a container. In the drawing, reference numeral 8 identifies the inner bag itself. The inner bag 8 mainly comprises a top surface 10, a bottom surface 12, a rear surface 14, side surfaces 16 and 18 and a front surface 20 which together substantially form a hollow hexahedron. The inner bag further includes hangers 22 and 24 and dump-up fixtures 26 for affixing the inner bag to the inside of a container.
Reference numerals 28 and 30 denote inlet or charging openings and a small outlet or discharging opening, respectively. In this illustrated example, the charging openings 28 are provided on the top surface 10 for loading of the goods, and the small discharging opening 30 is provided on the front surface 20 of the inner bag 8 for discharging or unloading the goods therefrom. Reference numerals 32 and 34 denote a screen canvas and a skirt canvas to form the front surface 20.
The inner bag shown in Fig. 1 is hung and extended in the container by the hangers 22 and 24 and the dump-up fixtures 26 and thereafter goods are accommodated in the inner bag.
., ~4~ 1302315 Fig. 2 is a perspective view schematically illustrating one embodiment of an inner bag for a container according to the invention. Reference numeral 40 denotes the inner bag itself. The inner bag ~10 comprises mainly a top surface 42, a bottom surface 44, a rear surface 46, side surfaces 48 and 50 and a front surface 52 to substantially form a hexahedron which is, of course, hollow.
Any appropriate construction of inner bag is acceptable. In this embodiment, for example, the inner bag is provided with an opening 54 at an upper portion of the front surface 52 for charging or loading goods and with a cover member 56 extending from a location above the opening 54 for opening and closing the opening 54.
Reference numeral 58 denotes fastening members, for example, surface fasteners. In this embodiment, an extending end of the cover member 56 is anchored to a substantial center portion of the front surface 52 by means of the fastening members 58 for closing the opening 54.
If the goods accommodated in the inner bag 40 are, for example, barleycorns for beer, the lower portion of the front surface 52 is provided with an opening by cutting part of the lower portion with a knife, so that if the container is tilted into a dump-up position then the barleycorns are discharged through the opening. When discharging corns, moreover, they may be unloaded through the opening 54 by means of a vacuum suction means.
Belt cloths 60 are provided along the edges of the inner bag in this embodiment so as to reinforce the inner bag 40.
Reference numerals 64, 66 and 68 identify fastening members provided on the inner bag for fastening the inner bag to the inner walls of a container.
In this embodiment, the fastening members 64 are provided at two corners on the upper portion of the front surface of the inner bag. The fastening members 68 are located at the upper and lower corners of the rear surface.
, Any suitable construction of the fastening members 64, 66 and 68 is acceptable. In this embodiment, for example, the fastening members 64 are case hanging devices. The fastening member 64 comprises a belt member 70 whose one end (the fixed end) is fixed to one corner of a side edge of the inner bag and the other end (the free end) is anchored to a buckle 74 which is provided on another side edge extending to another corner of the inner bag. An annular ring member 72 is provided at the corner and in Figure 2 it will be seen that the annular ring member 72 is maintained in position by a belt member 76, whilst buckle 74 is also maintained in position by means of the belt member 76.
Part of the belt member 70 between the fixed and free ends passes through the annular body 72 to form a partial loop. The loop is connected to an attachment point (not shown) on an inner wall of the container by means of a C-shaped mounting ring 78.
The fastening member 64 permits one to adjust the loop to a smaller size by pulling the free end of the belt member 70. When hanging and expanding the inner bag 40 in a container, the loop of the belt member 70 is reduced so as to apply tension to the inner bag 40.
The buckle 74 in this embodiment is provided with a stopper which is arranged so as not to anchor the free end of the belt member when it is pulled in such a direction as to make the loop smaller, i.e. the stopper is inoperative but is operative to anchor the free end when the belt member is pulled in a direction opposite to that direction which would make the loop smaller. As a result, the loop in the smaller size is held in this size by the buckle 74 by means of the stopper, so that the inner bag is maintained under tension.
The fastening member 66 comprises a similar annular body 72 located at the corner of the inner bag 40 as well as a belt member 82 whose one end (the fixed end) is fixed to a side edge of a corner of the inner bag and the other end (the free end) is anchored by a buckle 80 which is provided in the proximity of the side edge to which the -6- ~302315 one end is fixed. In this embodiment, the buckle 80 is held at the side edge of the corner of the inner bag with the aid of a belt member 76, and the annular body 72 is held at the side edge of the corner with the aid of a belt cloth 60.
In the fastening member 66, part of the belt member 82 passes through the annular body 72 to form a loop in the same manner as in the fastening member 64. The loop is connected to an attachment point of an inner wall of the container with the aid of a mounting ring 78 to enable the inner bag 40 to be placed under tension and expanded.
Moreover, the loops of the belt members 70 and 82 may be directly connected to the attachment points of the inner walls of the container.
The fastening member 68 in this embodiment comprises a belt member 84 fixed to a side edge of a corner of the inner bag 40 and a mounting ring 78 fixed to the belt member 84. In hanging and expanding the inner bag 40, the mounting ring 78 of the fastening member 68 is connected to an attachment point on an inner wall of the container.
In Fig. 2 reference numeral 86 denotes hygroscopic waterproof members which are provided partially or completely over the outer surfaces of the inner bag 40.
In this embodiment, the waterproof members 86 are made of an unwoven fabric and partially cover suitable areas of the front and rear portions of the top surface 42 in the form of belts. The waterproof members 86 provided on the top surfaces are indicated by shaded areas in the drawing. The respective waterproof members 86 on the top surface 42 preferably extend from the edge between the top surface and the one side surface to the edge between the top surface and the other side surface. As a result, the water is absorbed by the waterproof members 86 so as to prevent water remaining on slacks parts the top surface when the inner bag is hung and expanded in the container.
Thus water is prevented from entering the inner bag 40 through the top surface 42. Furthermore, this may prevent water on the top surface 42 from flowing along the inner bag 40 "x ~7 ~30231~;
and making contact with the goods whilst they are being discharged from the inner bag in a tilted, i.e. dump-up, position.
Advantageously, waterproof members 86 are provided at suitable locations of the front and rear portions of the lower surface 44 to partially cover it. In this case, the waterproof members 86 on the lower surface 44 preferably extend from the edge between the lower surface and the one side surface to the edge between the lower surface and the other side surface. As a result, the water is absorbed by the waterproof members 86 and this prevents the water from accumulating at the bottom surface and therefore prevents the water from entering the inner bag 40 through the bottom surface 44. Furthermore, this prevents the water on the bottom surface from flowing into the goods along the inner bag 40 whilst the goods are being discharged from the inner bag in its tilted or dump-up position.
It will be understood that the size, shape, area, etc. of the waterproof members 86 may be suitably selected at will.
This invention is not limited to the embodiment as above-described and may be modified in various manner depending upon design conditions.
For example, the waterproof members may be made from any suitable materials other than the unwoven fabric such as various kinds of papers, woven fabrics, spongy foam materials and the like. Moreover, the waterproof material may consist of a bag member and a hygroscopic solid, powdery or granular material accommodated in the bag member. In this case, part of the bag member may be made of a water permeable material and the remainder may be made of a waterproof material. Furthermore, all the bag member may be made of a waterproof material and the bag member may be formed with apertures of openings of such a size as to permit water to enter therethrough but not permit the hygroscopic material accommodated therein to go out of the bag member. Moreover, the waterproof member may be a composite member made up of a member f !~
having a waterproof property or made waterproof, and a hygroscopic member.
Moreover, the waterproof members may be provided at any suitable locations on the inner bag according to design requirements. For example, the waterproof members may be distributed all over the upper surface of the inner bag in any desired relationship. The waterproof members may cover all the top surface of the inner bag. The waterproof members may be provided on the side surfaces, the front surface or the rear surface in addition to the top and bottom surfaces. Moreover, the waterproof members may be provided on the inner bag so as to completely cover all the outer surfaces of the inner bag.
It will be appreciated that the fastening members, loading or unloading openings may be provided at any suitable locations, and any suitable design is acceptable.
This invention may be utilized in connection with previously-proposed inner bags of containers. The waterproof members may be provided on part, or all of the outer surfaces of the previously-proposed inner bags.
As can be seen from the above description, according to the present invention the waterproof members provided on part or all of the outer surfaces of the inner bag absorb the water when rain water or sea water enters the container or when dew is deposited on the outer surfaces of the inner bag. This absorption of water by the waterproof members prevents the water from entering the inner bag through its top or bottom surfaces and hence prevents the goods in the bag from being contaminated by the water.
In discharging the goods from the inner bag in a dump-up position, the waterproof members absorb the water accumulated on the upper or lower surface of the inner bag or water deposited in the form of dew as the water flows along the outer surfaces of the inner bag. The goods in the inner bag are thus protected from contamination by the water.
-9- ~302315;
It is further understood by those skilled in the art that the foregoing description is that of preferred embodiments of the disclosed bags and that various changes and modifications may be made in the invention without departing from the spirit and scope thereof.
Containers have been widely used on ships and trains for the bulk transportation of goods such as corn and other food, raw materials for industries, industrial goods and other loads. If these goods are directly loaded into the containers, the inside surfaces of the containers will most likely be contaminated by the goods.

In a further embodiment of the invention, the waterproof members are further provided on front and rear portions of the bottom surface in the form of belts, and particularly the waterproof members extend from an edge between the bottom surface and one side surface to an edge between the bottom surface and the other side surface.
With the inner bag constructed as above described, the waterproof members provided on part, parts or all of the outer surfaces of the inner bag absorb the water when rain water or sea water enters the container or dew is deposited on the outer surfaces of the inner bag to prevent the water from entering the inner bag, thereby preventing goods from being contaminated by the water.

In order that the invention may be more clearly understood, preferred embodiments will now be described, by way of example, with reference to the accompanying drawings in which:-,~
Fig. 1 is a schematic perspective view illustratingan inner bag for a container of the prior art; and Fig. 2 is a schematic perspective view illustrating one embodiment of an inner bag for a container according to the present invention.
DETAILED DE~;CRIPTION OF PREE'E:RRED E:M~ODI~!ENTS
The attached drawings are sufficiently schematic to an extent that the embodiments of the invention can be substantially understood and therefore shapes, dimensions and positional relationships between the respective components of the invention are not limited to those shown in the drawing.
One example of a prior inner bag as shown in Japanese Laid-open Patent Application No. 49-105,686 will be explained now by referring to Fig. 1.
Fig. 1 is a schematic perspective view illustrating the prior inner bag for a container. In the drawing, reference numeral 8 identifies the inner bag itself. The inner bag 8 mainly comprises a top surface 10, a bottom surface 12, a rear surface 14, side surfaces 16 and 18 and a front surface 20 which together substantially form a hollow hexahedron. The inner bag further includes hangers 22 and 24 and dump-up fixtures 26 for affixing the inner bag to the inside of a container.
Reference numerals 28 and 30 denote inlet or charging openings and a small outlet or discharging opening, respectively. In this illustrated example, the charging openings 28 are provided on the top surface 10 for loading of the goods, and the small discharging opening 30 is provided on the front surface 20 of the inner bag 8 for discharging or unloading the goods therefrom. Reference numerals 32 and 34 denote a screen canvas and a skirt canvas to form the front surface 20.
The inner bag shown in Fig. 1 is hung and extended in the container by the hangers 22 and 24 and the dump-up fixtures 26 and thereafter goods are accommodated in the inner bag.
., ~4~ 1302315 Fig. 2 is a perspective view schematically illustrating one embodiment of an inner bag for a container according to the invention. Reference numeral 40 denotes the inner bag itself. The inner bag ~10 comprises mainly a top surface 42, a bottom surface 44, a rear surface 46, side surfaces 48 and 50 and a front surface 52 to substantially form a hexahedron which is, of course, hollow.
Any appropriate construction of inner bag is acceptable. In this embodiment, for example, the inner bag is provided with an opening 54 at an upper portion of the front surface 52 for charging or loading goods and with a cover member 56 extending from a location above the opening 54 for opening and closing the opening 54.
Reference numeral 58 denotes fastening members, for example, surface fasteners. In this embodiment, an extending end of the cover member 56 is anchored to a substantial center portion of the front surface 52 by means of the fastening members 58 for closing the opening 54.
If the goods accommodated in the inner bag 40 are, for example, barleycorns for beer, the lower portion of the front surface 52 is provided with an opening by cutting part of the lower portion with a knife, so that if the container is tilted into a dump-up position then the barleycorns are discharged through the opening. When discharging corns, moreover, they may be unloaded through the opening 54 by means of a vacuum suction means.
Belt cloths 60 are provided along the edges of the inner bag in this embodiment so as to reinforce the inner bag 40.
Reference numerals 64, 66 and 68 identify fastening members provided on the inner bag for fastening the inner bag to the inner walls of a container.
In this embodiment, the fastening members 64 are provided at two corners on the upper portion of the front surface of the inner bag. The fastening members 68 are located at the upper and lower corners of the rear surface.
, Any suitable construction of the fastening members 64, 66 and 68 is acceptable. In this embodiment, for example, the fastening members 64 are case hanging devices. The fastening member 64 comprises a belt member 70 whose one end (the fixed end) is fixed to one corner of a side edge of the inner bag and the other end (the free end) is anchored to a buckle 74 which is provided on another side edge extending to another corner of the inner bag. An annular ring member 72 is provided at the corner and in Figure 2 it will be seen that the annular ring member 72 is maintained in position by a belt member 76, whilst buckle 74 is also maintained in position by means of the belt member 76.
Part of the belt member 70 between the fixed and free ends passes through the annular body 72 to form a partial loop. The loop is connected to an attachment point (not shown) on an inner wall of the container by means of a C-shaped mounting ring 78.
The fastening member 64 permits one to adjust the loop to a smaller size by pulling the free end of the belt member 70. When hanging and expanding the inner bag 40 in a container, the loop of the belt member 70 is reduced so as to apply tension to the inner bag 40.
The buckle 74 in this embodiment is provided with a stopper which is arranged so as not to anchor the free end of the belt member when it is pulled in such a direction as to make the loop smaller, i.e. the stopper is inoperative but is operative to anchor the free end when the belt member is pulled in a direction opposite to that direction which would make the loop smaller. As a result, the loop in the smaller size is held in this size by the buckle 74 by means of the stopper, so that the inner bag is maintained under tension.
The fastening member 66 comprises a similar annular body 72 located at the corner of the inner bag 40 as well as a belt member 82 whose one end (the fixed end) is fixed to a side edge of a corner of the inner bag and the other end (the free end) is anchored by a buckle 80 which is provided in the proximity of the side edge to which the -6- ~302315 one end is fixed. In this embodiment, the buckle 80 is held at the side edge of the corner of the inner bag with the aid of a belt member 76, and the annular body 72 is held at the side edge of the corner with the aid of a belt cloth 60.
In the fastening member 66, part of the belt member 82 passes through the annular body 72 to form a loop in the same manner as in the fastening member 64. The loop is connected to an attachment point of an inner wall of the container with the aid of a mounting ring 78 to enable the inner bag 40 to be placed under tension and expanded.
Moreover, the loops of the belt members 70 and 82 may be directly connected to the attachment points of the inner walls of the container.
The fastening member 68 in this embodiment comprises a belt member 84 fixed to a side edge of a corner of the inner bag 40 and a mounting ring 78 fixed to the belt member 84. In hanging and expanding the inner bag 40, the mounting ring 78 of the fastening member 68 is connected to an attachment point on an inner wall of the container.
In Fig. 2 reference numeral 86 denotes hygroscopic waterproof members which are provided partially or completely over the outer surfaces of the inner bag 40.
In this embodiment, the waterproof members 86 are made of an unwoven fabric and partially cover suitable areas of the front and rear portions of the top surface 42 in the form of belts. The waterproof members 86 provided on the top surfaces are indicated by shaded areas in the drawing. The respective waterproof members 86 on the top surface 42 preferably extend from the edge between the top surface and the one side surface to the edge between the top surface and the other side surface. As a result, the water is absorbed by the waterproof members 86 so as to prevent water remaining on slacks parts the top surface when the inner bag is hung and expanded in the container.
Thus water is prevented from entering the inner bag 40 through the top surface 42. Furthermore, this may prevent water on the top surface 42 from flowing along the inner bag 40 "x ~7 ~30231~;
and making contact with the goods whilst they are being discharged from the inner bag in a tilted, i.e. dump-up, position.
Advantageously, waterproof members 86 are provided at suitable locations of the front and rear portions of the lower surface 44 to partially cover it. In this case, the waterproof members 86 on the lower surface 44 preferably extend from the edge between the lower surface and the one side surface to the edge between the lower surface and the other side surface. As a result, the water is absorbed by the waterproof members 86 and this prevents the water from accumulating at the bottom surface and therefore prevents the water from entering the inner bag 40 through the bottom surface 44. Furthermore, this prevents the water on the bottom surface from flowing into the goods along the inner bag 40 whilst the goods are being discharged from the inner bag in its tilted or dump-up position.
It will be understood that the size, shape, area, etc. of the waterproof members 86 may be suitably selected at will.
This invention is not limited to the embodiment as above-described and may be modified in various manner depending upon design conditions.
For example, the waterproof members may be made from any suitable materials other than the unwoven fabric such as various kinds of papers, woven fabrics, spongy foam materials and the like. Moreover, the waterproof material may consist of a bag member and a hygroscopic solid, powdery or granular material accommodated in the bag member. In this case, part of the bag member may be made of a water permeable material and the remainder may be made of a waterproof material. Furthermore, all the bag member may be made of a waterproof material and the bag member may be formed with apertures of openings of such a size as to permit water to enter therethrough but not permit the hygroscopic material accommodated therein to go out of the bag member. Moreover, the waterproof member may be a composite member made up of a member f !~
having a waterproof property or made waterproof, and a hygroscopic member.
Moreover, the waterproof members may be provided at any suitable locations on the inner bag according to design requirements. For example, the waterproof members may be distributed all over the upper surface of the inner bag in any desired relationship. The waterproof members may cover all the top surface of the inner bag. The waterproof members may be provided on the side surfaces, the front surface or the rear surface in addition to the top and bottom surfaces. Moreover, the waterproof members may be provided on the inner bag so as to completely cover all the outer surfaces of the inner bag.
It will be appreciated that the fastening members, loading or unloading openings may be provided at any suitable locations, and any suitable design is acceptable.
This invention may be utilized in connection with previously-proposed inner bags of containers. The waterproof members may be provided on part, or all of the outer surfaces of the previously-proposed inner bags.
As can be seen from the above description, according to the present invention the waterproof members provided on part or all of the outer surfaces of the inner bag absorb the water when rain water or sea water enters the container or when dew is deposited on the outer surfaces of the inner bag. This absorption of water by the waterproof members prevents the water from entering the inner bag through its top or bottom surfaces and hence prevents the goods in the bag from being contaminated by the water.
In discharging the goods from the inner bag in a dump-up position, the waterproof members absorb the water accumulated on the upper or lower surface of the inner bag or water deposited in the form of dew as the water flows along the outer surfaces of the inner bag. The goods in the inner bag are thus protected from contamination by the water.

It is further understood by those skilled in the art that the foregoing description is that of preferred embodiments of the disclosed bags and that various changes and modifications may be made in the invention without departing from the spirit and scope thereof.
