Containment pant with positioning key

1. A method for providing a containment system comprising,

providing a containment pant comprising,

a chassis having a front waist region, a back waist region, and a crotch region joined between the front waist region and the back waist region, and

a sling positioned within the chassis and being joined to the front waist region and the back waist region, wherein the sling comprises a fluid-impervious base sheet and a containment flap joined with the base sheet to define a fluid-impervious pouch,

the fluid-impervious pouch defining a first end containment flap positioned proximate the front waist region and having a first positioning key,

the fluid-impervious pouch defining a second end containment flap positioned proximate the back waist region and having a second positioning key,

wherein the first end containment flap and the base sheet define a first end containment flap entrance width and the first positioning key separates the first end containment flap entrance width into a first flap sub-width and a second flap sub-width and

wherein the second end containment flap and the base sheet define a second end containment flap entrance width and the second positioning key separates the second end containment flap entrance width into a third flap sub-width and a fourth flap sub-width; providing a discrete absorbent insert comprising,

a first sheet,

a second sheet in facing relation with the first sheet,

an absorbent core positioned between the first sheet and the second sheet, wherein the absorbent core defines a core perimeter and a core width and includes a first absorbent core positioning notch and a second absorbent core positioning notch, wherein the first absorbent core sub-width is 80 to 100% the first flap sub-width, the second absorbent core sub-width is 80 to 100% the second flap sub-width, the third absorbent core sub-width is 80 to 100% the third flap sub-width, and the fourth absorbent core sub-width is 80 to 100% the fourth flap sub-width,

the first sheet and the second sheet extend beyond the core perimeter and are joined together to form a perimeter seal, the perimeter seal defines an absorbent insert perimeter which includes a first absorbent insert positioning notch and a second absorbent insert positioning notch,

the first absorbent core positioning notch separates the absorbent core width at a first end into a first absorbent core sub-width and a second absorbent core sub-width and the second absorbent core positioning notch separates the absorbent core width at a second end into a third absorbent core sub-width and a fourth absorbent core sub-width, inserting the discrete absorbent insert into the fluid-impervious pouch such that the first absorbent insert positioning notch is aligned with and partially surrounded by the first positioning key and the second absorbent insert positioning notch is aligned with and partially surrounded by the second positioning key.

2. The method of claim 1 wherein the first positioning key has a first key width and the discrete absorbent insert has a first absorbent core positioning notch width that is 100 to 150% the first positioning key width.

3. The method of claim 1 wherein the first end containment flap defines a first flap depth and wherein the second end containment flap defines a second flap depth and wherein the first positioning key defines a first key depth that is less than 25% the first flap depth and the second positioning key defines a second key depth that is less than 25% the second flap depth, and the

first absorbent insert positioning notch defines a first absorbent insert positioning notch depth that is at least 75% the first flap depth and the second absorbent insert positioning notch defines a second absorbent insert positioning notch depth that is at least 75% the second flap depth.
