Patent number: 10285877Abstract: The present disclosure provides a packaging unit for hygiene articles and a method for forming such a unit. The packaging unit has a first packaging function as a packaging wrap for a non-used article, and a second disposal function as a disposal wrap for a used article. The packaging unit further comprises a user prompting device having a wrap-facing surface and a user-facing surface, wherein the user prompting device is permanently attached to the wrap such that at least a portion of the wrap-facing surface of the user prompting device is in contact with the inner surface of the wrap. The user prompting device is arranged to prompt the user to employ the second disposal function of the packaging unit.Type: GrantFiled: June 13, 2014Date of Patent: May 14, 2019Assignee: ESSITY HYGIENE AND HEALTH AKTIEBOLAG ABInventors: Conny Dahlqvist, Ulrika Persson, Sofia Ekstedt

Patent number: 10086989Abstract: A packaging unit for hygiene articles, the unit being formed from a sheet of material having an inner surface, said inner surface comprising an edge portion being provided with a resealable adhesive for closure of the packaging unit. The sheet has a longitudinal center line and at least one transversely extending folding axis dividing the sheet into a first region and a second region. A tab is arranged at an edge portion of the first region. The tab extends in a longitudinal direction from said edge portion so that an extension of the tab along or parallel to the center line from a tab base to an outer edge of the tab is 0.5 cm or more. A method of forming the packaging unit is also provided.Type: GrantFiled: June 13, 2014Date of Patent: October 2, 2018Assignee: SCA Hygiene Products ABInventors: Conny Dahlqvist, Ulrika Persson, Sofia Ekstedt

Patent number: 10017309Abstract: A packaging unit for hygiene articles that is formed from a sheet of material having an inner surface comprises an edge zone comprising an inner edge portion and an outer edge portion. At least one of the outer and inner edge portions comprises at least one region provided with a resealable adhesive. The sheet has at least one folding axis dividing said sheet into a first and second regions region. The sheet is folded about said at least one folding axis with said first and second regions in an overlapping configuration, thereby providing a packaging unit. Overlapping outer edge portions of the sheet layers are at least partly adhesive-free and are at least partially connected to each other by a mechanical interaction providing a sealing strength of 0.2 to 1.5 N. A method for forming the packaging unit is provided.Type: GrantFiled: June 13, 2014Date of Patent: July 10, 2018Assignee: SCA Hygiene Products ABInventors: Conny Dahlqvist, Ulrika Persson, Sofia Ekstedt

Patent number: 9834355Abstract: A packaging unit for hygiene articles is formed from a sheet having a folding axis dividing the sheet into first and second regions. One of the inner edge portion and the outer edge portion of the edge zone of the first region is provided with resealable adhesive, thus forming a first adhesive zone. The other of the inner edge portion and the outer edge portion is adhesive-free. The inner edge portion or the outer edge portion of the edge zone of the second region corresponding to the adhesive-carrying edge portion of the first region is adhesive-free, such that when the sheet is folded about the folding axis, the edge portions carrying resealable adhesive in the first region are brought in contact with the adhesive-free edge portions in the second region. A distance between the at least one first folding axis and the first adhesive zone is 1-20 mm.Type: GrantFiled: June 13, 2014Date of Patent: December 5, 2017Assignee: SCA HYGIENE PRODUCTS ABInventors: Conny Dahlqvist, Ulrika Persson, Sofia Ekstedt
