The present disclosure relates, generally, to an absorbent article for personal feminine care. The present disclosure more particularly relates to a sanitary pad having a raised portion for positioning, at least partially, within the vestibule of a wearer for absorbing mensural fluid.
To provide protection for feminine consumers experiencing conditions leading to the release of the mensural fluid, consumer product manufacturers have developed a wide range of personal care absorbent articles. Sanitary pads are one such absorbent articles having high absorptive capacity. However, the sanitary pads tend to move away from the vaginal orifice due to compressive forces of the wearer's thighs in the pudendal region or during any physical movement, such as walking or any another movement. Such movement of the sanitary pad may lead to leakage of mensural fluid leading to soiling of garments of a wearer which is not desirable.
According to an aspect of the disclosure, a sanitary pad for absorbing the human exudate is disclosed. The sanitary pad has a first surface and a second surface disposed opposite to the first surface. Further, the sanitary pad includes a raised portion disposed substantially centrally to the sanitary pad and extending outwardly from the first surface. The raised portion is adapted to be inserted, at least partially, within a vestibule of a wearer to facilitate an absorption of mensural fluid of a wearer. Also, the insertion of the raised portion facilitates an alignment and securing of the sanitary pad with the vestibule.
According to another aspect of the disclosure, a sanitary pad for absorbing human exudate is disclosed. The sanitary pad includes a first surface and a second surface disposed opposite to the first surface. Further, the sanitary pad includes a raised portion disposed substantially centrally to the sanitary pad and extending outwardly from the first surface. The raised portion is adapted to be inserted, at least partially, within a vestibule of a wearer for facilitating an absorption of mensural fluid. The insertion of the raised portion facilitates an alignment and securing of the sanitary pad with the vestibule. The sanitary pad further includes a first peripheral portion having a first barrier and a first groove disposed surrounding the raised portion. Furthermore, the sanitary pad includes a second peripheral portion having a second barrier and a second grove disposed spaced apart from the first groove and surrounding the first groove.
According to yet another aspect of the disclosure a sanitary pad for absorbing human exudate is disclosed. The sanitary pad includes a first surface and a second surface disposed opposite to the first surface. The sanitary pad also includes a first raised portion disposed substantially centrally to the sanitary pad and extending outwardly from the first surface. The first raised portion is adapted to be inserted, at least partially, within a vestibule of a wearer for facilitating an absorption of mensural fluid. The insertion of the first raised portion facilitates an alignment and securing of the sanitary pad with the vestibule. Further, the sanitary pad includes a first peripheral portion having a first barrier and a first groove disposed surrounding the first raised portion. Furthermore, the sanitary pad includes a second peripheral portion having a second barrier and a second groove disposed spaced apart from the first groove and surrounding the first groove. The sanitary pad also includes a second raised portion disposed spaced apart from the first raised portion and extending outwardly from the first surface. The second raised portion is disposed proximate to a second longitudinal end of sanitary pad and is adapted for insertion, at least partially, into an anal region of the wearer.
For a more complete understanding of the present invention, reference is made to the following detailed description and accompanying drawings. In the drawing, like reference characters refer to like parts throughout the views in which:

Further, the elongated structure 102, and hence the pad 100, includes a first peripheral portion 170 surrounding the first raised portion 130 and may be disposed spaced apart from the first raised portion 130. The first peripheral portion 170 defines a first groove 172 disposed spaced apart from the first raised portion 130 and extending along an entire periphery of the base 134. Therefore, the first groove 172 provides a substantially elliptical channel surrounding the first raised portion 130 for receiving and collecting any fluid flowing from the first raised portion 130. Surrounding the first groove 172 is a first barrier 174 for obstructing the flow of the fluids received inside the first groove 172 to spread across the pad 100. In an embodiment the first barrier 174 may be defined by a raised wall of the first groove 172. Additionally, the elongated structure 102, and hence the pad 100, includes a second peripheral portion 180 disposed surrounding the first peripheral portion 170 and a defining a second groove 182 disposed spaced apart from the first groove 172 and extending along an entire periphery or circumference of the first peripheral portion 170. Therefore, the second groove 182 provides an elliptical channel surrounding the first peripheral portion 170 or the first barrier 174 for receiving and collecting any fluid overflowing from the first groove 172. Surrounding the second groove 182 is a second barrier 184 for obstructing the flow of the fluid received inside the second groove 182 to spread across the pad 100. In an embodiment the second barrier 184 may be defined by a raised wall of the second groove 182.
Additionally, or optionally, the elongated structure 102, and hence the pad 100, includes a second raised portion 188 extending outwardly from the first surface 132, and disposed space apart from the first raised portion 130 and proximate to the second longitudinal end 112. As shown, the second raised portion 188 is disposed along the longitudinal axis 150 and is located between the second groove 182 and the second longitudinal end 11. Further, the second raised portion 188 may include a base 190 that may be substantially elliptical. In such a case, a major axis of the base 190 may be substantially parallel to the longitudinal axis 150, while a minor axis of the base 190 may be substantially parallel to the lateral axis 152. In an embodiment, the major axis of the base 134 of the first raised portion 130 and the major axis of the base 190 of the second raised portion 188 coincide with the longitudinal axis 150. In an embodiment, the second raised portion 188 may include a height smaller than a height of the first raised portion 130, and a length smaller than a length of the first raised portion 130. The second raised portion 188 is adapted for insertion into the anal region 204 between the buttocks of the wearer 200 for providing a leak proof packaging of the pad 100 between the vestibule 206 and the buttocks of the wearer 200. In this manner, the second raised portion 188 facilitates for the proper alignment of the pad 100 when the wearer 200 is lying on the side or during sleeping positions. Further, the first flap 104 includes two portions 300,302 separated by a first gap ‘G1’. Similarly, the second flap 106 also includes two portions 304, 306 separated by a second gap ‘G2’.
Further, as shown in
To facilitate absorption of the fluid by the third layer 198, the first layer 192 is a liquid permeable layer, while the second layer 194 is a liquid impermeable layer to prevent a leakage of the fluid through the pad 100. In certain implementations, the first layer 192 may suitably be made from a soft, textile like material or non-woven-fabric. Other example of the suitable material is perforated plastic film, knitted or woven textiles as well as combination and laminates of multiple materials. Also, the second layer 194 may include polymer films of polyethylene and polypropylene. As shown in

An application of the pad 100, 100′ and 100″ is now disclosed. When the pad 100, 100′ and 100″ is worn by the wearer 200, a portion of the first raised portion 130 is disposed/inserted inside the vestibule 206 of the wearer 200. The partial insertion of the first raised portion 130 in the vestibule 206 of the wearer 200 facilitates a rapid absorption of the mensural fluid. Also, the partially inserted first raised portion 130 ensures a higher absorption of the mensural fluid by residing inside the vaginal cavity and occluding the flow of mensural fluid. Further, the insertion of the first raised portion 130 inside the vestibule 206 and an insertion of the second raised portion 188 inside the anal region 204 ensure a proper alignment of the pad 100, 100′, and 100″ and prevent any movement of the pad 100, 100′ and 100″ relative to the body of the wearer 200.
