Patent number: 11523716Abstract: A dispenser assembly designed to tangentially dispense a sheet from a roll of sheet material including sheet material formed from two webs, each web having lines of weakness positioned transversely across the web which allows the web to be separated into a plurality of sheets, the lines of weakness of one web being offset from those of the other web. The dispenser assembly includes (1) a base arranged to hold the roll of sheet material and to couple the dispenser assembly with an environment structure; (2) a first roller and a counter roller between which the sheet material is movable towards a dispensing outlet; and (3) a cradle arranged to support the roll of sheet material and to unwind the sheet material towards the first roller whatever a consumption level of the roll of sheet material.Type: GrantFiled: March 22, 2013Date of Patent: December 13, 2022Assignee: ESSITY OPERATIONS FRANCEInventors: Julien Marietta-Tondin, Yves Stoeffler, Gilles Cattacin

Patent number: 11246461Abstract: A sheet product dispenser for dispensing a strip of a sheet product from a static center-feed coreless roll of sheet product is disclosed. The roll includes a central cavity. The dispenser includes a container for accommodating the roll, and a dispensing piece which protrudes toward an interior of the container from one end of the container and which includes a guidance between a receiving opening for receiving the strip of sheet product from the roll and a dispensing opening for dispensing the strip of sheet product outside of the dispenser. The dispensing piece is arranged to engage into the central cavity of the roll. The dispensers provide a dispensing opening so that withdrawal of a sheet product is facilitated by avoiding collapsing or clogging. Furthermore, the dispenser has a compact configuration that gains space during delivery and transportation.Type: GrantFiled: October 18, 2012Date of Patent: February 15, 2022Assignee: ESSITY OPERATIONS FRANCEInventors: Julien Marietta-Tondin, Gilles Cattacin, James Taylor

Patent number: 11206958Abstract: The toilet paper dispenser as claimed for the invention including a housing in which is housed a roll of a paper strip, which has perforations transverse to strip defining rectangular paper sheets whose width is transverse and whose length is longitudinal. Housing features a nozzle with a dispensing orifice, by means of which the paper strip is unwound. The dispenser is characterized in that the nozzle and the paper roll are disposed in such a way that the paper sheets unwind one by one and emerge with a reduced crumpling as they exit the nozzle, the width of a sheet is between 125 mm and 180 mm, and the ratio of the width of a sheet to its length is between 0.45 and 1, preferably between 0.5 and 0.65, the paper being consumed optimally and in a pleasant manner.Type: GrantFiled: March 26, 2008Date of Patent: December 28, 2021Assignee: ESSITY OPERATIONS FRANCEInventor: Jean-Louis Neveu

Patent number: 10626557Abstract: A fibrous sheet having a basis weight of between 20 and 1000 g/m2 that disintegrates in water, has 10% to 70% starch on the basis of the total weight of the dry fibrous sheet. The disintegration time in water, measured in accordance with standard NF Q34-020 applied to a specimen of the sheet of 9×8 cm2, is less than 50 seconds. A loss of strength of the sheet measured in accordance with a defined table test corresponds to a loss of strength of a specimen of said sheet forming an angle of at least 85° after having being wetted with water for a duration of 6 seconds, and/or a residual wet strength of the sheet relative to its dry strength, as measured according to a defined ring crush test, is less than 1%. The fibrous sheet may be used for the manufacture of a water disintegrable core in a roll of tissue paper.Type: GrantFiled: August 28, 2014Date of Patent: April 21, 2020Assignee: ESSITY OPERATIONS FRANCEInventors: Philippe Colin, Jean-Claude Dozzi, Pierre Probst, Véronique Wiss, Rémy Ruppel

Patent number: 10463204Abstract: A coreless roll of absorbent sheet products is made of a spirally wound web of absorbent substrate including at least two superposed plies of absorbent substrate, the web of absorbent substrate being wound such as to define an axial hollow passageway centrally positioned relatively to the coreless roll and extending from one edge to another edge of the coreless roll. The web of absorbent substrate further includes a stiffening insert, the stiffening insert being inserted in-between two superposed plies of absorbent substrate, the stiffening insert being positioned such as to line the axial hollow passageway, the stiffening insert having a length such that the stiffening insert extends at least around three quarter of a circumference of the passageway, preferably substantially completely around a circumference of the passageway.Type: GrantFiled: February 16, 2015Date of Patent: November 5, 2019Assignee: ESSITY OPERATIONS FRANCEInventor: Donald Barredo

Patent number: 10350850Abstract: A core intended to support a reel of paper, particularly toilet paper, is formed by winding at least one web of cellulose wadding. The core is formed by winding at least one web of cellulose wadding having at least 0.51 g of water-soluble material per gram of cellulose wadding, the water-soluble material being designed to make the web of cellulose wadding more rigid and easier to disintegrate. Thus configured, the core that has both mechanical strength fit for the intended purpose and is far easier to disintegrate than a core mad of cardboard such that it can be disposed of directly in a toilet bowl without the risk of blocking the waste pipe.Type: GrantFiled: January 29, 2016Date of Patent: July 16, 2019Assignee: ESSITY OPERATIONS FRANCEInventors: Frédéric Roesch, Nicolas Weisang, Rémy Ruppel, Pierre Probst

Patent number: 10271693Abstract: A roll of wiping paper is obtained by winding a sheet of multi-ply absorbent paper around a core. The sheet includes at least a first and a second ply of absorbent paper, each with a grammage of between 15 and 30 g/m2 and at least one of the plies incorporating a wet strength additive. The thickness of the sheet Ep being between 0.02 and 0.07 cm, the diameter of the core being less than 3.5 cm, the diameter of the roll being between 4.5 cm and 11 cm for a volume V of absorbent paper per unit length of the roll, and the absorbency A of the sheet in cm3 of water per gram of paper being greater than 6 cm3/g. The ratio E=A/(Ep*V) of the roll is greater than or equal to 3.2.Type: GrantFiled: May 25, 2016Date of Patent: April 30, 2019Assignee: ESSITY OPERATIONS FRANCEInventors: Pierre Graff, Gerald Duhen, Donald Barredo, Pierre Probst, Pascale Saas

Patent number: 10213066Abstract: A coreless roll of an absorbent sheet product, such as napkins, toilet paper, towels etc., including a spirally wound continuous web of absorbent material having a first end and a second end and a coating composition comprising a specific polymer coated onto the second end is disclosed. The coreless roll has excellent resistance to collapsing, as well as excellent flexibility and elasticity. Moreover, the coreless roll has excellent disintegrability in water and can be used along its whole length. Also disclosed is a process for the manufacture of the coreless roll.Type: GrantFiled: April 1, 2016Date of Patent: February 26, 2019Assignee: ESSITY OPERATIONS FRANCEInventors: Nicolas Weisang, Donald Barredo
