Abstract

A substantially cuboid reclosable flexible package ( 8 ) for transporting multiple personal hygiene absorbent articles “on-the-go” is disclosed. It has a front wall ( 81 ), a rear wall ( 82 ), two opposed side walls ( 83,83 ) and two opposed end walls ( 84,84 ′). It includes a stack of at least two personal hygiene absorbent articles ( 1,100 ) comprising a garment attachment adhesive covered by a removable release paper ( 2 ), and which are folded inwardly with the removable release paper ( 2 ) exposed. The folded absorbent articles are free of an individual wrapping pouch and comprise closure means ( 7 ) for securing said folding. The package ( 8 ) is made of a plastic or paper wrap sealed at one position on either the front ( 81 ), the rear ( 82 ), or one of the two side walls ( 83,83 ′), and on the two end walls ( 84,84 ′). It comprises, on at least one wall, a tear-open flap ( 86 ) limited by at least one tearing line ( 87 ).

First claim

The invention claimed is:

1. A process for making a substantially cuboid reclosable flexible package ( 8 ) of personal hygiene absorbent articles ( 1 , 100 ) free of an individual wrapping pouch, having a front wall ( 81 ), a rear wall ( 82 ), two opposed side walls ( 83 , 83 ′) and two opposed end walls ( 84 , 84 ′), comprising the steps of:
(i) providing personal hygiene absorbent articles ( 1 , 100 ) comprising a garment attachment adhesive covered by a removable release paper ( 2 ), wherein each individual absorbent article ( 1 , 100 ) has a central section ( 4 ), an inner-outboard section ( 5 ) and an outer-outboard section ( 6 ), and wherein each individual absorbent article ( 1 , 100 ) is asymmetric between the outboard sections ( 5 , 6 ) and an outboard section extends laterally outward of the central section ( 4 );
(ii) folding inwardly along two spaced-apart laterally oriented fold lines ( 3 ) the inner-outboard section ( 5 ) and the outer-outboard section ( 6 ) of each individual absorbent article ( 1 , 100 ) into a folded article wherein the removable release paper ( 2 ) is exposed;
(iii) providing each folded article with closure means ( 7 ) for securing the folded article;
(iv) stacking at least two folded articles;
(v) wrapping a wrapping material around the resulting stack of folded articles;
(vi) sealing the wrapping material at one position on either the front ( 81 ), the rear ( 82 ), or one of the two side walls ( 83 , 83 ′), and on the two end walls ( 84 , 84 ′);
(vii) providing at least one wall of the package with a tear-open flap ( 86 ) limited by at least one tearing line ( 87 ).

2. The process according to claim 1 , wherein a closing element ( 88 ) is further provided, which is connected at its respective ends to adjacent wall portions of said package ( 8 ) on opposite sides of said tearing line ( 87 ).

3. The process according to claim 1 , wherein the personal hygiene absorbent articles ( 1 , 100 ) are provided by assembling a liquid impermeable backsheet ( 12 ), a liquid permeable topsheet ( 10 ) and an absorbent core ( 11 ) between the backsheet ( 12 ) and the topsheet ( 10 ), and the folding is done so that the folded articles have at most two superimposed layers of absorbent core ( 11 ).

4. The process according to claim 1 , wherein the closure means ( 7 ) comprise a closing tape ( 7 ) crossing and adhering in a resealable manner to the outer-outboard section ( 6 ) and to the inner-outboard section ( 5 ).

5. The process according to claim 1 , wherein the wrapping and sealing steps comprise:
(a) delivering a continuous rectangular sheet of wrapping material;
(b) wrapping the sheet around the stack of folded articles;
(c) cutting the sheet longer than the periphery of the stack to create an overlap region ( 85 );
(d) sealing the sheet in the overlap region ( 85 ) to form a tube around the articles;
(e) folding over the open ends ( 840 ) of the tube towards the stack of articles;
(f) sealing said folded open ends.

6. The process according to claim 1 , wherein the tear-open flap ( 86 ) is provided in an end region of the front ( 81 ) or rear ( 82 ) wall and narrows to a grippable flap end ( 861 ), and wherein two tearing lines depart ( 87 , 87 ′) from the flap end ( 861 ) towards corners of the package ( 8 ) within said end region.

7. The process according to claim 6 , wherein the tearing lines ( 871 , 871 ′) extend into the region of the end wall ( 84 ).

8. The process according to claim 6 , wherein a closing element ( 88 ) is adhered to the tear-open flap ( 86 ), overlaps the flap end ( 861 ) and is connected releasably to the front ( 81 ) or rear ( 82 ) wall.

9. The process according to claim 1 , wherein the folded absorbent articles are arranged so that a fold ( 9 ) faces a package opening formed by the tear-open flap ( 86 ).

10. The process according to claim 1 , wherein the absorbent articles ( 1 , 100 ) are progressing along the manufacturing line in cross-machine direction, at least during steps (i) and (ii).

11. The process according to claim 10 , wherein the absorbent articles ( 1 , 100 ) are progressing along the manufacturing line in cross-machine direction, at least during steps (i), (ii), (iii) and (iv).

12. A substantially cuboid reclosable flexible package ( 8 ) of personal hygiene absorbent articles ( 1 , 100 ), having a front wall ( 81 ), a rear wall ( 82 ), two opposed side walls ( 83 , 83 ′) and two opposed end walls ( 84 , 84 ′), wherein the package ( 8 ) includes a stack of at least two personal hygiene absorbent articles ( 1 , 100 ) comprising a garment attachment adhesive covered by a removable release paper ( 2 ), wherein each personal hygiene absorbent article ( 1 , 100 ) has a central section ( 4 ), an inner-outboard section ( 5 ) and an outer-outboard section ( 6 ), and wherein each personal hygiene individual absorbent article ( 1 , 100 ) is asymmetric between the outboard sections ( 5 , 6 ) and an outboard section extends laterally outward of the central section ( 4 ), and wherein the inner-outboard section ( 5 ) and the outer-outboard section ( 6 ) of each personal hygiene individual absorbent article ( 1 , 100 ) are folded inwardly along two spaced-apart laterally oriented fold lines ( 3 ) with the removable release paper ( 2 ) exposed, characterised in that the folded absorbent articles are free of an individual wrapping pouch and comprise closure means ( 7 ) for securing the folded absorbent articles and characterised in that the package ( 8 ) is made of a wrapping material sealed at one position on either the front ( 81 ), the rear ( 82 ), or one of the two side walls ( 83 , 83 ′), and on the two end walls ( 84 , 84 ′), and in that it comprises, on at least one wall, a tear-open flap ( 86 ) limited by at least one tearing line ( 87 ).

13. The package according to claim 12 , characterised in that it comprises a closing element ( 88 ) connected at its respective ends to adjacent wall portions of said package ( 8 ) on opposite sides of said tearing line ( 87 ).

14. The package according to claim 12 , wherein the folded absorbent articles are arranged so that a fold ( 9 ) faces a package opening formed by the tear-open flap ( 86 ).

15. A process for making a substantially cuboid reclosable flexible package ( 8 ) of personal hygiene absorbent articles ( 1 , 100 ) free of an individual wrapping pouch, having a front wall ( 81 ), a rear wall ( 82 ), two opposed side walls ( 83 , 83 ′) and two opposed end walls ( 84 , 84 ′), comprising the steps of:
(i) providing personal hygiene absorbent articles ( 1 , 100 ) comprising a garment attachment adhesive covered by a removable release paper ( 2 ), wherein each individual absorbent article ( 1 , 100 ) has a central section ( 4 ), an inner-outboard section ( 5 ) and an outer-outboard section ( 6 ), and wherein each individual absorbent article ( 1 , 100 ) is asymmetric between the outboard sections ( 5 , 6 ) and an outboard section extends laterally outward of the central section ( 4 );
(ii) folding inwardly along two spaced-apart laterally oriented fold lines ( 3 ) the inner-outboard section ( 5 ) and the outer-outboard section ( 6 ) of each individual absorbent article ( 1 , 100 ) into a folded article wherein the removable release paper ( 2 ) is exposed;
(iii) providing each folded article with closure means ( 7 ) for securing the folded article;
