Abstract

The invention relates to method for placing a garbage sack made of paper into a stand for filling, and for removing the filled sack from the stand. The sack has inwardly deflected lateral folds (1), and the sack is higher than the stand. The sack also has a lower fold (5) parallel to the bottom. When the sack has been filled, it is raised by the mouth, whereby the lower fold is straightened and the contents are dropped on the bottom of the sack. After this the mouth of the sack can be easily closed.

Description

Method for placing a sack into a stand and removing out of i

The present invention concerns the placing of a garbage sack made of paper into a stand for filling, and the removal of the filled sack from the stand. The invention also concerns a sack to be used in the method and the preparation of the sack.

In households, at present, garbage is collected in plastic sacks placed in particular stands. In view of protection of the environment, it would, however, be preferable to use sacks made of paper or of a corresponding readily decomposing material for this purpose. In the presen systems based on garbage sacks made of paper, conventional paper sacks are used, which sacks are placed empty into the stand so that the bottom of the sack is set against the bottom of the stand. It is natural that people attempt to fill the sack up to the mouth level of the stand. Because of the relative stiffness of the paper mantle, it is then difficult to close the mouth. It is also hard to fold a strip from the mouth of the paper sack against the outer edge of the stand, by means of which strip the sack filled up to the edge of the stand could be closed.

Now a system has been invented, in which a paper sack comprising inwardly deflected lateral folds and a transversal fold at a distance from the bottom is placed into the stand. The sack is placed into the stand so that the folded part is set against the bottom of the stand. After the sack has been filled it is raised by its mouth whereby the fold is opened and the contents are dropped to the bottom of the sack and free mantle is left at the mouth for closing. Preferably the distance of the fold from the bottom is the same as the width of the lateral fold. The sides of the sack bent along the fold can be attached ligthly together e.g. with a glue dissolving in moisture. A preferable embodiment of the invention will be described in the following in more detail with reference to the accompanying drawings. In the drawings, Figures 1 and 2 illustrate the sack when empty and flattened, Figure 3 shows the sack opened and placed in the stand, and Figure 4 shows the sack filled and closed.

The sack is made of a single-layer or multi-layer paper hose blank. The material that is used is, e.g., kraft paper that has been treated so as to give it an adequate wet strength. The circumferential dimension of the hose corresponds to the inner circumferential dimension of the sack stand. The blank is provided with lateral folds 1, whose length when opened is equal to the width of the stand. Thereat, the width of an unopened sack is equal to the length of the stand, and the sack can be placed easily into the stand.

About 15 to 20 cm long cuts 2 are made to the corners of the mouth portion of the sack. These cuts permit folding of the mouth portion of the sack as four separate strips over the edges of the stand. In this way the sack can be attached to the stand.

The bottom 3 of the sack is sealed by using a double adhesive fold. In this way a good sealing is obtained for liquids. Moreover, onto the bottom a bottom patch 4 made of a strong material is applied by means of adhesive, said bottom patch extending across the bottom when the sack is filled. The bottom patch protects the sack bottom from abrasion when a filled sack is, e.g., pulled along the ground while holding the sack by its mouth portion. The height of the sack from the bottom ends of the cuts at the mouth portion to the bottom of the sack is made by one and a half times the width of the stand longer than the height of the sack stand. The sack is folded along a fold 5 parallel to the bottom, placed at the distance of the width of the sack stand from the sack bottom, and, counted from the said fold, at a further distance of half the width of the stand along a second fold 6 in the opposite direction. The sack sides placed against each other at the latter fold are further attached to each other lightly in a suitable way, e.g. by means of a glue point 7, tape, or equivalent. It is particularly recommendable to use an adhesive that dissolves by the effect of moisture. When the sack is now opened and placed into the stand, the folded portion remains unopened on the stand bottom. The portion opened as a layer equal to the width of the stand fills the stand completely and can be packed full even forcibly without tearing the sack. When the sack is now removed from its stand and raised by its mouth portion, the bottom fold is opened and the contents fall down onto the bottom proper of the sack. At the same time, a sufficient amount of sack wall becomes free at the mouth portion, whereby the sack can be closed and tied readily.

Claims

Claims
1. Method for placing a garbage sack made of paper into a stand for filling, and for removing the filled sack from the stand, in which said method a paper sack is placed into a box-shaped stand, the said sack being provided with a cylindrical mantle, an open mouth at one end of the mantle and a cross-folded bottom at the opposite end, as well as with folds (1) extending from the ends of the bottom seam to the mouth of the sack, and the filled sack is removed from the stand, c h a r a c t e r i z e d in 'that into the stand a sack is placed whose height from the bottom to the lowest point of the mouth is larger than the height of the stand and in which said sack there is a lower fold (5) parallel to the bottom at a distance from the bottom so that the folded part of the mantle is set against the bottom of the stand, and that, after filling, the sack is lifted by the mouth so that the fold is opened and the sack is filled down to the bottom.
2. Method as claimed in claim 1, c h a r a c t e r - i z e d in that the distance of the lower fold (5) from the bottom is equal to the width of the opened fold (1).
3. Method as claimed in claim 1 or 2, c h a r a c ¬ t e r i z e d in that the sack is further provided with an upper fold (6) placed at a distance from the lower fold (5) towards the mouth.
4. Method as claimed in claims 2 and 3, c h a r a c ¬ t e r i z e d in that the distance of the upper fold (6) from the lower fold (5) is half the width of the opened fold (1).
5. Method as claimed in any of the claims 1 to 4, c h a r a c t e r i z e d in that the sack sides folded against each other at the lower or upper fold (5/6) are attached to each other lightly.
6. Method as claimed in claim 5, c h a r a c t e r - i z e d in that the sack sides folded against each other are attached to each other by means of a glue that dissolves in moisture.
7. Method as claimed in any of the claims 1 to 6, c h a r a c t e r i z e d in that at the mouth of the sack, at the lateral creases of the folds (1), there are cuts (2) parallel to the creases of the folds.
8. Method as claimed in any of the claims 1 to 7, c h a r a c t e r i z e d in that the height of the sack, measured from the bottom to the lowest point of the mouth, is larger than the height of the filling stand.
9. Paper sack for garbage to be filled in a stand, which said sack comprises a cylindrical mantle, at one end of the mantle an open mouth and at the opposite and a cross-folded bottom, as well as, facing the ends of the bottom joint, inwardly deflected folds (1) extending from the bottom to the mouth, c h a r a c t e r i z e d in that the sack is provided with a lower fold (5) parallel to the bottom and placed at a distance from the bottom.
10. Process for the manufacture of a paper sack to be used in a stand, in which said method a hose is formed out of a paper web, folds are made inwards at opposite sides of the hose, a piece is cut off the hose and one of the piece is seamed to make the bottom of the sack, an open mouth being formed at the opposite end, c h a r a c t e r i z e d in that hereupon the sack is folded at a distance from the bottom along a fold (5) parallel to the bottom.
