Tampon method of manufacture
View Patent ↗A pledget for a tampon having improved leakage prevention of bodily fluid after the tampon is inserted in the vagina. The pledget can have an absorbent structure having two layers. At least one of the layers of the absorbent structure can have one contact element at least partially separated from a second contact element. A method of manufacturing the tampon can include a step of incorporating a contact element into at least one of the two layers of the absorbent structure.
1. A method of manufacturing a pledget, the method comprising the steps of:
a. forming a nonwoven ribbon, the method of forming the nonwoven ribbon comprising the steps of:
i. providing a first layer of fibrous material having a first surface and a second surface;
ii. providing a second layer of fibrous material having a first surface and a second surface; and
iii. placing the first layer and the second layer into communication with each other to create the nonwoven ribbon;
b. incorporating a fold into the first layer of fibrous material wherein a first portion of the first surface of the first layer is brought into communication with a second portion of the first surface of the first layer;
c. incorporating a first contact element and a second contact element into the first layer by incorporating at least three successive slits into the first layer wherein each slit is cut through the fold in the first layer;
d. separating an individual unit of fleece from the nonwoven ribbon wherein the individual unit of fleece comprises a portion of the first layer of fibrous material, a portion of the second layer of fibrous material, the first contact element and the second contact element; and
e. compressing the individual unit of fleece.
2. The method of claim 1 further comprising the step of rolling, stacking or folding the individual unit of fleece prior to compressing the individual unit of fleece into a pledget.
3. The method of claim 1 wherein the step of placing the first layer of fibrous material and the second layer of fibrous material into communication with each other further includes the step of bonding the first layer and the second layer to each other.
4. The method of claim 1 further comprising the step of providing a cover.
5. The method of claim 1 wherein the first layer has a first transverse edge and a second transverse edge and the second layer has a first transverse edge and a second transverse edge.
6. The method of claim 5 wherein the step of placing the first layer and the second layer into communication with each other further comprises the step of aligning one of the first transverse edge or the second transverse edge of the first layer to one of the first transverse edge or the second transverse edge of the second layer.
