An absorbent element for the absorption of body fluids in sanitary articles comprises a first layer of sheet material presenting an array of hollowed formations () with respective mouth parts, as well as masses () of superabsorbent material that is able to expand as a result of the absorption of body fluid, which are set in the aforesaid hollowed formations (). A second layer of sheet material () is applied on the first layer of sheet material () so as to cover the mouth parts of the hollowed formations (). At least one of the layers of sheet material () is permeable to body fluids to enable the body fluids themselves to penetrate into the hollowed formations and be absorbed by the masses of superabsorbent material () that expand in the hollowed formations (), creating a first level of absorption of body fluids. The second layer of sheet material () is compliant in an area corresponding to the mouth parts of the hollowed formations () and enables further expansion of said masses of superabsorbent material () beyond said hollowed formations () so as to create a second level of absorption of body fluids. The first layer () and the second layer () of sheet material are connected to one another by adhesive formations () that leave the mouth parts of the hollowed formations () at least partially free.

Absorbing element for sanitary products, having expandable pockets containing superabsorbent material and manufacturing process

A closure element () with elastic side panels for absorbent pant-like sanitary products (), said element () being formed starting from a strip () at least partially made of elasticised material () folded in transverse direction so as to form two parts (), symmetrical relative to a central transverse plane (), each of said parts () being able to form a side panel () of an absorbent sanitary product (), said closure element () comprising: &#x2014;a first branch () that extends continuously through said central transverse plane (); &#x2014;two second branches () connected to respective opposite ends of the first branch () by means of respective first folds (), distal relative to said central transverse plane (), in which the first branch () and the two second branches () have respective mutually facing surfaces () permanently fastened to each other; &#x2014;two third branches () connected to respective ends of second branches () by means of respective second folds (), proximal and distanced relative to said central transverse plane (); &#x2014;two fourth branches () connected to respective ends of the two third branches () in distal positions relative to said central transverse plane (); and&#x2014;two fifth branches () connected to respective ends of the fourth branches () by means of respective third folds (), proximal and distanced relative to said central transverse plane ().

Closure element with elastic side panels for absorbent sanitary products, absorbent sanitary product and respective manufacturing method

A stack of interleaved laminar products comprises a first and a second array of products, each of which has at least one branch interleaved with a corresponding branch of at least one product in the other array. The products are folded into a generally W-shaped profile comprising two outer branches and two inner branches, with the distal edges of the said outer branches projecting at least partially beyond the said inner branches, so that the said distal edges can be used for interleaving with at least one other product in the stack.
