PANTS-TYPE DIAPER AND CORRESPONDING MANUFACTURING PROCESS

1 . An absorbent sanitary product wearable as a pant-like garment, including:

a central body including an absorbent portion defining a crotch portion of the product, said central body having two opposite ends, and

two side panels extending laterally from said central body at each said opposite ends to define respective portions of the waist line of the product whereby a pair of complementary side panels is provided at each side of said central body, each side panel of said side panels having a distal edge connected to a distal edge of the complementary side panel at the opposite end of said central body via a refastenable hook-and-loop closure including complementary hook and loop elements;

wherein in each pair of complementary side panels:

one of the panels carries at a surface thereof facing inwardly of the product one of the complementary hook and loop elements of said hook-and-loop closure;

the other panel has a distal edge thereof folded over itself inwardly of the product to form an end loop portion and a marginal rim, said marginal rim being sandwiched between the two complementary side panels; and

said marginal rim carries at a surface thereof facing toward said one of the panels the other of the complementary hook and loop elements of said hook-and-loop closure.

2 . The product of claim 1 wherein the hook element of said hook-and-loop closure comprises surface loops of the material comprising the corresponding side panel.

3 . The product of claim 1 wherein folded-over side panel carries the loop element of said hook-and-loop closure.

4 . The product of claim 1 wherein folded-over side panel carries the hook element of said hook-and-loop closure.

5 . The product of claim 1 wherein said marginal rim sandwiched between the two complementary side panels is temporarily connected to the corresponding side panel, the temporary connection releasable when the product is opened up to be worn.

6 . The product of claim 1 including elasticated formations extending at the sides of said central body, each elasticated formation extending between two said complementary side panels to provide a close fit of the product around the wearer's leg, wherein each said elasticated formation includes:

an intermediate portion connected to said central body, and

two end portions extending away from said intermediate portion, wherein said end portions extend in correspondence with said side panels, said end portions being exempt from connection with said central body.

7 . The product of claim 1 wherein at least one side panel in said pair of complementary side panels is elasticated.

8 . An absorbent sanitary product wearable as a pant-like garment, including:

a central body including an absorbent portion defining a crotch portion of the product, said central body having two opposite ends, and

two side panels extending laterally from said central body at each said opposite ends to define respective portions of the waist line of the product whereby a pair of complementary side panels is provided at each side of said central body, each said side panel having a distal edge connected to a distal edge of the complementary side panel at the opposite end of said central body via a refastenable hook-and-loop closure including complementary hook and loop elements, wherein:

at least one of said complementary hook and loop elements of said refastenable hook-and-loop closure includes:

active areas carrying either hook or loop elements, and

flexible passive areas between said active areas, said passive areas being free of hook and loop elements.

9 . The product of claim 8 wherein said active areas carry hooks of a hook-and-loop closure.

10 . The product of claim 8 wherein said active areas are regularly spaced at a constant distance therebetween.

11 . A method of producing a sanitary product according to claim 1 , the method including:

providing said central body for said product.

connecting one said pair of complementary side panels at each side of said central body, and

folding said central body having said side panels connected thereto in a V-like or U-like shape at a line intermediate said end portions bringing the side panels in each pair of said complementary side panels in a facing arrangement whereby the distal edges of said complementary side panels abut against each other producing engagement of the hook and loop portions of said hook-and-loop closure at each side of the product.

12 . The product of claim 2 wherein folded-over side panel carries the loop element of said hook-and-loop closure.

13 . The product of claim 2 wherein folded-over side panel carries the hook element of said hook-and-loop closure.

14 . The product of claim 2 wherein said marginal rim sandwiched between the two complementary side panels is temporarily connected to the corresponding side panel, the temporary connection releasable when the product is opened up to be worn.

15 . The product of claim 3 wherein said marginal rim sandwiched between the two complementary side panels is temporarily connected to the corresponding side panel, the temporary connection releasable when the product is opened up to be worn.

16 . The product of claim 4 wherein said marginal rim sandwiched between the two complementary side panels is temporarily connected to the corresponding side panel, the temporary connection releasable when the product is opened up to be worn.

17 . The product of claim 2 including elasticated formations extending at the sides of said central body, each elasticated formation extending between two said complementary side panels to provide a close fit of the product around the wearer's leg, wherein each said elasticated formation includes:

an intermediate portion connected to said central body, and

two end portions extending away from said intermediate portion, wherein said end portions extend in correspondence with said side panels, said end portions being exempt from connection with said central body.

18 . The product of claim 3 including elasticated formations extending at the sides of said central body, each elasticated formation extending between two said complementary side panels to provide a close fit of the product around the wearer's leg, wherein each said elasticated formation includes:

an intermediate portion connected to said central body, and

two end portions extending away from said intermediate portion, wherein said end portions extend in correspondence with said side panels, said end portions being exempt from connection with said central body.

19 . The product of claim 4 including elasticated formations extending at the sides of said central body, each elasticated formation extending between two said complementary side panels to provide a close fit of the product around the wearer's leg, wherein each said elasticated formation includes:

an intermediate portion connected to said central body, and

two end portions extending away from said intermediate portion, wherein said end portions extend in correspondence with said side panels, said end portions being exempt from connection with said central body.

20 . The product of claim 5 including elasticated formations extending at the sides of said central body, each elasticated formation extending between two said complementary side panels to provide a close fit of the product around the wearer's leg, wherein each said elasticated formation includes:

an intermediate portion connected to said central body, and

two end portions extending away from said intermediate portion, wherein said end portions extend in correspondence with said side panels, said end portions being exempt from connection with said central body.
