A container for a stack of individually removable paper products () such as facial tissues, handkerchiefs, towels and the like, or similar products made of non-woven material is described. The container has an upper wall (), in which a withdrawal opening is formed which is closed by a tear-off-able lid () and a cavity accommodating the stack of products. The lid () has on its inner surface () an adhesive or bonding surface () by which the uppermost paper product () of the stack adheres, preferably detachably, to the lid ().

A fibrous structure is described for use in hygienic articles such as diapers, sanitary napkins, incontinence guards, wipes and the like, having one or more polar, silicon containing compounds bound to at least one portion of the surface of the fibrous structure by interaction between the surface and the silicon containing compounds. The fibrous structure exhibits a predetermined degree of hydrophilicity and adhesion properties which are substantially unaffected by wetting of the fibrous structure. Absorbent, hygienic and textile articles comprising such a fibrous structure are also described.

Fibrous structure and absorbent article including such a fibrous structure

The invention relates to a container for a collection of interfolded or mechanically connected tissue-sheets, the container having a generally planar bottom wall and a top wall and a pair of side walls and a par of end walls connecting the bottom wall with the top wall and an opening provided in at least the top wall for the removal of the tissue-sheets from the container, the stack of interfolded tissue-sheets being placed in the container with at least a pair of edges of a lowermost tissue-sheet placed on the bottom wall and an uppermost tissue-sheet placed near or in contact with the top wall and adjacent to the opening in the top wall. The opening is provided with elongated projections extending from opposite sides of the opening, wherein each projection in an initial position extends across the opening in the plane of the top wall and is positioned adjoining at least one opposing projection, and the projections are arranged in co-operating pairs, wherein each projection has at least one inner section having a smaller width than an adjacent outer section.

Container for a stack of interfolded tissue sheets and a method for manufacturing such a container

An absorbent, porous structure ( ), intended for use in an absorbent article, wherein the structure ( ) exhibits a first region ( ), primarily consisting of a first material, which stands in direct connection with a second region ( ), primarily conssisting of a second material. The receding wetting angle &thgr; is larger for the first material than for the second material, whereby liquid transport between the two regions ( ) takes place in a direction from the first region ( ) to the second region ( ), at least when the porous structure ( ) is wet.

Absorbent structure having improved absorption properties

An absorbent article, such as a sanitary napkin, a panty-liner, or a diaper includes a carrier layer against which individual fibers, detached from each other and each exhibiting two fiber ends, are attached with one fiber end against the carrier layer. There is an attachment angle &agr; between the carrier layer and each individual fiber. The individual fibers have at least a first fiber type and a second fiber type. The absorbent article further includes a liquid-pervious cover layer and a liquid acquisition layer.

A method increases the wet strength of a tissue material, and a tissue material ( &prime;) which has been subjected to the method. The wet strength agent included in the tissue material ( &prime;) has an intrinsic, normal wet strength-increasing effect which can be achieved by a curing course having chemical reactions and/or physical interactions between different reactive sites of the wet strength agent, between different reactive sites of the cellulose fibres, and reaction and/or interaction between the reactive sites of the wet strength agent and of the cellulose fibres, resulting in a network of polymers which is kept together by bonds. The method includes formation of radicals and/or excited conditions with high reactivity in gas phase at atmospheric pressure, wherein the radicals and/or excited conditions increase the number of the reactions and/or interactions and/or the number of the reactive sites and thereby also the number of bonds, so that the strength of the network is increased and the tissue material ( &prime;) is conferred an increased wet strength. The method can be implemented for all tissue paper materials which include cellulose fibres and a suitable wet strength agent.

The invention relates to an absorption material ( ) comprising a carrier material exhibiting a coating ( ) of a thermosensitive polymer with a cloud point at a temperature in the vicinity of and somewhat below the body temperature of a healthy human being. The absorption properties of the polymer change at the cloud point, so that the polymer substantially lacks absorption capacity at a first temperature on one side of the cloud point but exhibits good absorption properties at a second temperature on the other side of the cloud point. Furthermore, the invention includes an absorbent article such as a diaper, an incontinence protector, a sanitary napkin, or the like, having an absorption body comprising an absorption material coated with a thermosensitive polymer.

Absorption material having temperature dependent absorption capacity and the use thereof in an absorbent article

A superabsorbent fiber or a nonwoven material including a thermoplastic polymeric fiber to which solid particles of superabsorbent material have been thermobonded by heating the polymeric fiber to a temperature at which adhesion is obtained between the fiber and the particles and a method of making the same. Also, an absorbent article is produced including such a superabsorbent fiber or nonwoven material.
