PACKAGING UNIT FOR A DISPOSABLE HYGIENE ARTICLE AND METHOD OF FORMING THE PACKAGING UNIT
A packaging unit includes a sheet of packaging material and a disposable hygiene article extending in a longitudinal direction of the elongated sheet and placed on the inner surface of the sheet such that it fits within an area limited by side edge zones and a first longitudinal end zone. The unit is formed by folding the elongated sheet and the disposable hygiene article. The first longitudinal end zone includes at least two adjacent, in the direction transverse to the longitudinal direction of the elongated sheet, resealable adhesive coating strings that extend along the length of the first longitudinal end zone and the strings are arranged such that a central adhesive free area is formed. This adhesive area functions as a gripping gap. A method of forming the packaging unit is also described.

wherein the article has an end portion having a pre-determined length that extends beyond the second longitudinal end zone, and
wherein the unit is arranged to be folded along a first folding axis such that the third region is pressed against the second region and the end portion that extends beyond the second longitudinal end zone is pressed against the first region, and the unit is further arranged to be folded along the second folding axis such that the first region together with the end portion are pressed against the outer surface of the elongated sheet in the third region, whereby the end portion forms a gripping portion when the unit is opened.
2 . The packaging unit according to claim 1 , wherein the disposable hygiene article is placed on the inner surface of the sheet at a predetermined distance from the resealable adhesive coating strings in the first longitudinal end zone, in the direction of a central axis of the unit.
3 . (canceled)
4 . (canceled)
5 . The packaging unit according to claim 1 , wherein the end portion comprises a second end edge of the article, which second end edge has a rounded shape.
6 . The packaging unit according to claim 1 , wherein the disposable hygiene article comprises a release liner releasably fastened to a garment facing side of the article by means of an adhesive and wherein the release liner is fastened to the inner surface of the elongated sheet by means of adhesive.
7 . The packaging unit according to claim 6 , wherein the release liner is fastened to the inner surface of the elongated sheet by means of separate adhesive regions placed in the first, second and third region, respectively.
8 . The packaging unit according to claim 1 , wherein the disposable hygiene article is fastened directly to the inner surface of the elongated sheet-by means of adhesive.
9 . The packaging unit according to claim 8 , wherein the inner surface of the elongated sheet-is coated with a silicone-based coating in areas where the hygiene article is placed and wherein the areas where the resealable adhesive is coated as the resealable adhesive coating strings are free of the silicone-based coating.
10 . The packaging unit according to claim 1 , wherein the elongated sheet has a rectangular shape.
11 . The packaging unit according to claim 1 , wherein the elongated sheet of packaging material is a plastic film, nonwoven or plastic laminate having a basis weight of 20-30 g/m 2 .
12 . The packaging unit according to claim 1 , wherein the second longitudinal end zone between the resealable adhesive coating strings in the side edge zones is adhesive-free.
13 . The packaging unit according to claim 1 , wherein an adhesive free gap is formed between the resealable adhesive coating strings extending along the side edge zones of the sheet and the resealable adhesive coating strings extending along the first longitudinal edge zone.
14 . The packaging unit according to claim 1 , wherein the resealable adhesive is a pressure sensitive hotmelt adhesive.
15 . The packaging unit according to claim 1 , wherein said elongated sheet is opaque or comprises print.
16 . A method of forming a packaging unit for a disposable hygiene article, comprising the steps of:
providing an elongated sheet of packaging material having an inner surface and an outer surface a first longitudinal end zone and a second longitudinal end zone, wherein the longitudinal end zones extend in a direction transverse to a longitudinal direction of the elongated sheet, and two side edge zones which extend in the longitudinal direction of the elongated sheet,
attaching an elongated disposable hygiene article extending in the longitudinal direction of the elongated sheet and placing the article on the inner surface of the sheet so that it fits within the area limited by the side edge zones and the first longitudinal end zone,
coating resealable adhesive strings along the length of each of the side edge zones and the first longitudinal end zone, and forming a central adhesive free area between the resealable adhesive coating strings in the first longitudinal end zone to form a gripping gap,
providing a first folding axis and a second folding axis in a direction transverse to the longitudinal direction of the unit which divide the unit into a first region, second region and a third region,
folding the elongated sheet with the disposable hygiene article along the first folding axis inwards, such that the inner surface of the elongated sheet and the resealable adhesive coating strings extending along the side edge zones in the third region and the second region are pressed against each other,
folding the elongated sheet with the disposable hygiene article along the second folding axis inwards, such that the outer surface of the sheet in the third region is pressed against the resealable adhesive coating strings in the first region and the inner surface of the sheet in the first region, and
closing the packaging unit by applying pressure,
wherein when folding the elongated sheet of the packaging material and the disposable hygiene article along the first folding axis inwards such that the inner surface of the elongated sheet and the resealable adhesive coating strings in the side edge zones are pressed against each other, and when the third region is pressed against the outer surface of the sheet in the second region, an end portion extending beyond the second end zone is pressed against the first region, and when folding the elongated sheet with the disposable hygiene article along the second folding axis inwards such that the outer surface of the sheet in the third region is pressed against the resealable adhesive coating strings in the first region and the inner surface of the sheet in the first region, the end portion is pressed towards the first folding axis and therefore forms a gripping portion when the unit is opened.
