Abstract
A tampon has a pair of longitudinally extending side edges and an absorbent member. The absorbent member has an insertion area, a withdrawal area, and an intermediate area between the insertion area and the withdrawal area and an attachment area. The absorbent material has a plurality of fiber integrated nonwoven layers but are without fiber integration adjacent layers outboard of the attachment area. A withdrawal line extends from the withdrawal area and is attached to the absorbent member in the attachment area such that each of the plurality of absorbent layers is attached to an adjacent nonwoven layer in the attachment area.
Claims8
A tampon comprising an absorbent member, comprising:
- an insertion area, a withdrawal area, an intermediate area between the insertion area and the withdrawal area, and an attachment area;
- a nonwoven web in a folded configuration in which the nonwoven web is folded over on itself to form a structure having a plurality of layers of the nonwoven web,
- wherein each of the layers extends along a plane along a longitudinal direction parallel with a longitudinal axis of the absorbent member, and a lateral direction perpendicular to the longitudinal direction;
- and wherein the layers are stacked along a z-direction perpendicular to the plane, and
- wherein the layers are sewn together in the attachment area to form a unitary stack including the plurality of layers, such that at least two of the plurality of layers are fiber integrated with an adjacent layer via the sewing in the attachment area;
- and
- a withdrawal line extending from the withdrawal area and attached to the absorbent member in the attachment area.
A tampon comprising an absorbent member, comprising:
- an insertion area, a withdrawal area, an intermediate area between the insertion area and the withdrawal area, and an attachment area;
- a first section of nonwoven web forming a first layer;
- and
- a second section of nonwoven web forming a second layer,
- wherein each of the first and second layers extends along a plane along a longitudinal direction parallel with a longitudinal axis of the absorbent member, and a lateral direction perpendicular to the longitudinal direction;
- and wherein the layers are stacked directly adjacent each other along a z-direction perpendicular to the plane, and
- wherein the first and second layers are sewn together in the attachment area to form a unitary stack including the first and second layers, such that the first and second layers are fiber integrated with each other via the sewing in the attachment area;
- and
- a withdrawal line extending from the withdrawal area and attached to the absorbent member in the attachment area.
A method of producing a tampon comprising the steps of:
- providing a nonwoven web;
- folding the nonwoven web over on itself to form a structure having a plurality of layers of the nonwoven web,
- arranging the layers in a stack along a z-direction to form a layered configuration, whereby each of the layers extends along a plane along a longitudinal direction parallel with a longitudinal axis of the tampon when completed, and a lateral direction perpendicular to the longitudinal direction, the z-direction being perpendicular to the plane;
- providing a withdrawal line;
- and
- sewing the layers together in an attachment area such that at least two adjacent layers in the stack are fiber integrated in the attachment area, to form a unitary absorbent member comprising the layers;
- and
- attaching the withdrawal line to the absorbent member in the attachment area,
- wherein one or more of the layers is not fiber integrated with another of the layers in areas outboard of the attachment area.
