FI90331B - Procedure for packing pulp goods in a large pack, and large pack designed for pulp goods - Google Patents

Abstract

The invention concerns a procedure for packing pulp goods in a large package, and a large package designed for pulp goods. The large package comprises an inner packing 11 and an outer packing 16,16a,16b,16c. The inner packing 11 is a sack of flexible material which, when being filled with pulp goods, is placed on the base 13, whereby the inner packing takes up the shape of a parallelopiped during the filling. The outer packing encloses the inner packing 11 tightly, and this outer packing is of a plastic material which provides sufficient stability and rigidity. <IMAGE>

Description

90 331

The invention relates to a method for packing bulk goods in a large package 10 The invention relates to a method for packaging bulk goods in a large package and to a bulk packaging for bulk packaging in a bulk package.

The invention also relates to a large package for bulk goods.

15 Box packaging or other rigid packaging on a pallet (usually a pallet) is used for the packaging, storage and transport of bulk goods. Box packages consist of corrugated cardboard boxes. The corrugated box is usually equipped with an inner bag. Such a package has a rectangular shape when filled and thus makes maximum use of the transport platform, although the package as such is expensive.

Large bags are also used for packing, storing and transporting bulk goods. The big bag is cheaper than a box package, but its disadvantage is its round shape when filled, which means that it uses the transport platform less favorably than a box package.

It is an object of the invention to provide a method for packaging bulk goods in a flexible package and a flexible package for bulk goods which, when filled, assumes an almost rectangular shape and in which standard pallets (e.g. EUR, FIN pallets) can be used as a base. In this way, the maximum use of space in a box package can be combined with the low price of a flexible package. At the same time, the recycling of used packaging can be better handled because no sorting is required, 35 but the flexible packaging is recovered as such and the standard pallet is returned to circulation. In the case of a box package, the box, the inner bag and the tray have to be separated and the recovery has to be handled through three different systems.

The method according to the invention for packing bulk goods in a large package is characterized in that (a) an inner package of flexible material with a support structure is placed on a base, (b) the inner package is filled with bulk goods, the inner package being substantially parallelepiped-shaped, and surrounded by an outer package of plastic material to form a stable transport package.

The bulk package according to the invention is characterized in that the inner package is an inner bag of flexible material with a support structure which is placed on the base during filling with bulk, preferably by hanging or supporting above the base, and that the outer package is tightly surrounding the inner package and the base. outer packaging of plastic material.

In the method according to the invention, it has been realized to use a large package consisting of a flexible inner package of inexpensive material and an surrounding outer package which gives the large package sufficient strength. As the flexible material of the inner package, which has a relatively low stiffness, e.g. plastic films, paper or fabrics can be used. The flexible package is hung or supported above a suitable platform, such as a pallet, during filling of the bulk material. After filling with bulk material, the inner package with a possible support structure is bonded to the substrate, e.g. with a stretch film 30, so that a sturdy whole is formed, i.e. a large package. The width of the stretch film is not an essential factor. The width of the stretch film can be a conventional width, such as about 500 mm, but a full-length stretch film of the entire height of the inner package can also be used as the stretch film. Instead of a stretch film, it is of course also possible to use a ki-35 cross hood or a shrink hood.

The support structure may be a separate support structure or part of the inner package acting as a support structure at the same time.

The large package according to the invention is characterized in that the inner package of the large package withstands the stresses imposed by the filling phase and that the circumference of the inner package filled with bulk material does not substantially increase during the filling phase. It should be noted that during filling, the inner package is allowed to spread slightly, i.e. to deform and apply to a rectangular shape, which is then later easily surrounded by a stretch film to provide the final large package.

The large packaging according to the invention makes it possible to recycle the used flexible packaging-10 materials. In addition, the pallet used in the large package can be stored and reused after the large package has been emptied.

The large package filled with bulk material according to the invention is a sufficiently upright and functional unit, which also withstands storage and transport well. The large package according to the invention is easy to lift, e.g. in storage, by lifting the large package with the forks of the truck from the openings in the pallet.

20 The inner packaging, the outer packaging and the pallet form an assembly which is easily stackable and which does not substantially change shape during stacking and storage.

One of the most significant advantages of the invention is that the Large-25 package according to the invention can be made of a substantially smaller amount of material than an ordinary large bag, because the lifting capacity required by the safety factor is not required, as is the case with large sacks with lifting loops.

Figure 7 shows a schematic side view of a fifth preferred embodiment of a finished large package according to the invention.

In the embodiment according to Figure 1, the inner package is marked with the reference number 11. The inner package 11 is provided with a support structure 12. In this embodiment, the support structure 12 and the inner package 11 placed outside it form a substantially rectangular whole.

The embodiment according to Fig. 2 is otherwise the same as the embodiment shown in Fig. 1 except that in the embodiment according to Fig. 2 the inner package 11 and the support structure 12 form a parallelepiped-shaped whole.

As best seen in Figure 3, the inner package 11 and any support structure 12 are placed on a suitable base such as a pallet 13. The openings in the pallet 13 are indicated by reference numeral 14. The inner package 11 is filled with bulk material. an outer package 16, 35 surrounding the inner package 11 is formed which gives the large package sufficient stability.

The embodiment shown in Fig. 4 differs from the embodiment according to Fig. 3 in that in the embodiment according to Fig. 4 the inner package 11 is surrounded by a full-width stretch film 16a.

The embodiment shown in Fig. 5 is otherwise the same as the embodiment shown in Fig. 4, but in the embodiment according to Fig. 5, the full-width stretch film 16a is provided with a seam 17.

In the embodiment of Figure 6, the bulk package-filled inner package 11 is surrounded by a tension or shrink hood 16b which forms the outer package of the large package.

In the embodiment according to Figure 7, the inner package 11 filled with bulk material is surrounded by a so-called with a tension or shrink sock 16c forming the outer package of the large package.

In the large package according to the invention, it is advantageous, but not necessary, to use a support structure 12. The purpose of the support structure 12 is that the inner package 11 filled with bulk goods better retains its "rectangular" shape.

On the other hand, the large package cannot be formed from the inner package 11 alone. Even if the inner package 11 is made of a stronger material, the inner package 11 can only withstand the stresses of filling, but such inner package 11 can no longer withstand storage (handling) and transport.

Only some preferred embodiments of the invention have been described above, and it will be apparent to those skilled in the art that numerous modifications may be made thereto within the scope of the inventive idea set forth in the appended claims.
