An assembly of bags comprising a protection bag

Abstract: This invention is related to a protection bag made of polyethylene, laminated polypropylene woven material or any other suitable material for the protection of the bags inserted inside thereof used for the handling, storing and transporting of bulk materials against various environment conditions wherein the opening of the protection bag is extended to one side and a slit is provided on the bag through which a lifting hook or any other handling means may be inserted.

Description: This invention is related to an assembly of bags comprising a protection bag which provides protection against outer effects during handling, storing and transporting of an inner and an outer bag used for filling, storing and transporting granular of powdered bulk materials. In general, the bags used for storing and handling of bulk materials may hold quantities of 500 kg to 1500 kg. These bags consist of an inner bag made of usually polyethylene in which the bulk material is filled and an outer bag made of polypropylene woven material the top part of which is cut vertically and sewn to form a lifting handle. The inner bag is filled with the bulk material and the opening is closed and the bag is carried by the handle. These bags are designed to endure transporting for a very long time under various transportation conditions. As a result of various weather conditions such as rain, snow and wind, the space between the inner bag and outer bag may be filled with rainwater or dust. This is detrimental to the bags and the bulk material as well. On the other hand, the outer bag may be soiled due to the exposition to environment and the notices placed onto the bags such as "flammable, poisonous, dangerous" may become illegible and this may cause undesired results. In the prior art, containers used for handling and transportation of bulk materials are inserted into another bag made of polyethylene or similar material and the opening is closed afterwards. In the upper part of the outer bag, a hook is placed onto the handling loop for lifting the bag. This hook pierces the outer bag and therefore rainwater, dust or any other undesired materials may enter into the space between the inner and the outer bags. In order to avoid the above mentioned disadvantages of the bulk material bags, the subject of this invention is to provide an assembly of bags which prevents the interference of the various environment conditions and on the other hand which facilitates handling. According to this invention there is provided an assembly of bags, comprising a protection bag made of polyethylene, laminated polypropylene woven material or any other suitable material for the protection of an inner and an outer bag which are inserted inside the protection bag, said assembly being used for the handling, storing and transporting of bulk materials against various environment conditions, wherein the protection bag comprises an opening on one side thereof and wherein a slit is provided in the protection bag close to the opening thereof through which a lifting hook or any other handling means may be inserted, wherein the said slit is cut through both sides of the protection bag, wherein the area around the said slit is sealed by welding, sewing or using adhesives in order to prevent the penetration of unwanted elements such as rainwater or dust into the contents of the bag, and wherein the top part of the outer bag has a lengthwise cut in order to insert the said outer bag into the protection bag and in order to enable the inner bag into which the bulk material is placed to be inserted into the said outer bag and the protection bag, respectively. The invention will be described in detail herebelow with reference to the drawings in which Figure 1 shows the protection bag, Figure 2 shows the protection bag into which the outer bag is inserted, Figure 3 shows the opening of the outer bag, Figure 4 shows the sewn outer bag and the protection bag, Figure 5 shows the lifting loop which is prepared by the top part of the protection bag and the opening of the outer bag, and Figure 6 shows the final position of the outer bag and the protection bag. The protection bag 1 is made of a plastic material such as laminated polypropylene or polyethylene etc. and may be of any geometrical design such as circular, rectangular, elliptical or cubic. One part of the bag is left open. A slit 2 is cut close to the opening part of the bag and parallel to the side edge of the protection bag. The slit 2 may be of any design, the edges 3 of the slit are sealed by welding, sewing or using adhesives in order to form a single slit which prevents the penetration of any undesired materials such as water or dust into it. After the sealing, the protection bag 1 is ready for use. The top part of the outer bag 4 ist cut lengthwise 5 in order to insert the inner bag (not shown) into the outer bag 4 and to provide a lifting and handling loop 8 as well. The outer bag 4 is inserted into the protection bag 1 through the wider portion between the slit 2 and the adjacent side of the protection bag 1 and one side of the outer bag 4 adjacent the cut 5 is pulled up from the other side of the slit 2. The opening of the outer bag 4 and folding lines 6 are sewn together. Thus the protection bag 1 provides protection for the bag 4 inserted into it. Thereafter, the opening of the protection bag 1 is pulled to one side 10 and the part of the protection bag 1 close to the sewn part 7 of the outer bag 4 is fastened by a string made of polypropylene woven material, polyethylene material or a similar material. This provides the lifting and handling loop 8. According to this invention, the bag 4 which is inserted into the protection bag 1 will be protected against the environment and the opening 10 of the protection bag 1 will enable the bag which is inserted in it to be filled. After the inner bag in the outer bag 4 is filled with bulk material, the opening 10 of the protection bag 1 is fastened by means of a string. The string may either be attached to the lifting and handling loop 8 or provided separately. The protection bag 1 according to this invention to which a hook for lifting the bag is inserted into the handling loop without creating any problem and which provides protection against the environment during handling and storing of the bags may be manufactured in any other form or design.

Claims: An assembly of bags, comprising a protection bag (1) made of polyethylene, laminated polypropylene woven material or any other suitable material for the protection of an inner and an outer bag (4) which are inserted inside the protection bag (1), said assembly being used for the handling, storing and transporting of bulk materials against various environment conditions, wherein the protection bag (1) comprises an opening on one side thereof and wherein a slit (2) is provided in the protection bag (1) close to the opening thereof through which a lifting hook or any other handling means may be inserted, wherein the said slit (2) is cut through both sides of the protection bag (1), wherein the area around the said slit (2) is sealed by welding, sewing or using adhesives in order to prevent the penetration of unwanted elements such as rainwater or dust into the contents of the bag, and wherein the top part of the outer bag (4) has a lengthwise cut (5) in order to insert the said outer bag (4) into the protection bag (1) and in order to enable the inner bag into which the bulk material is placeable to be inserted into the said outer bag (4) and the protection bag (1), respectively.
