This invention relates to a sanitary pad and more particularly to an extra absorbent sanitary pad for protecting a user during initial periods of heavy flow during the menstrual cycle. Heavy flow during the menstrual cycle can result in some anxiety for a woman because of the consequences of leakage. Obviously leakage can result from flow from front, side and rear portions of the sanitary pad. The most critical problems exist in the front and rear of the pads. One way to address that concern is by using more than one sanitary pad. This solution however does not necessarily solve the problems associated with leakage at the front and rear of the pads. Thus it is desirable to have a single sanitary pad that contains and eliminates leakage that may result from the front and rear of the pads during times of unusually heavy menstrual flow.
There have been some attempts to deal with issue of leakage associated with sanitary pads. However none of these products specifically address the need to assure that there is no leakage at the front and rear of the pad. However some of the products do address the leakage issue at the rear of the pad. One such arrangement is disclosed in U.S. Pat. No. 7,196,241B2. This patent discloses a sanitary napkin in which diffusing liquid hardly reaches a rear edge that is adapted to make a liquid absorbent layer less deformable in a rear region so that it can easily be kept in close contact with the wearer's buttocks. The sanitary napkin has an elongated main absorbent region surrounded by compressed grooves that are formed in a skin-side surface. Since a rear end of the main absorbent region is far away from a rear edge of the napkin to provide a relatively large region, therefore worries about rearward leakage would be relieved.
Despite this there is still a need for a product that addresses the leakage issue at both ends of the pad during periods of heavier than usual menstrual flow.
A sanitary pad is provided for eliminating incidents of leakage for a user. The sanitary pad of this invention includes a lower fluid-impervious base member. An engaging member is coupled to each side of the base member for securely engaging adjacent outside surfaces of and under garment of a user. An intermediate liquid absorbent member is adjacently coupled to the base member. The invention also includes a pair of spaced raised, longitudinally extending absorbent guide members aligned in and coupled to the intermediate member. The sanitary pad also includes a first oval shaped liquid absorbent member which is coupled to one end and sides of the intermediate liquid absorbent member and a second oval shaped liquid absorbent member which is coupled to another end and other sides of the liquid intermediate absorbent member thereby preventing leakage from the front and rear of the sanitary pad.
The details of the invention will be described in connection with the accompanying drawing in which:
Referring to
The sanitary pad 10 also includes an intermediate liquid absorbent member, generally designated, by the numeral, 16 which is adjacently coupled to and aligned with the base member 12. (
A first absorbent end member, generally designed, by the numeral, 22 is aligned with and coupled to extend outwardly from one end 24 and sides 26 of the intermediate liquid absorbent member 16. The first absorbent member 22 extends outwardly from the end 24 and sides 26 of the intermediate liquid absorbent member 16 in an oval configuration. A second absorbent end member, generally designated, by the numeral 28 is aligned with and coupled to extend outwardly from another end 30 and sides 32 of the intermediate absorbent member 16 in an oval configuration. The first and second absorbent members 22 and 28 are provided to eliminate leakage at the front and rear ends of the sanitary pad 10 particularly during periods of heavy flow. The first and second absorbent end members 22, and 28 can each be made, for example, of a single piece of cotton like absorbent material or a plurality of spaced aligned pieces of cotton like absorbent material 34 as illustrated in the figures.
When it is desired to use the sanitary pad 10 a user can simply couple the pad to the user's under garment by using the wing shaped engaging members 14 in a well known manner. This will properly position the intermediate liquid absorbent member 16 in the under garment of the user and allow the absorbent end member 22 to extend upwardly and outwardly in an oval configuration in the front of the user's torso and the absorbent end member 28 to extend upwardly and outwardly in an oval configuration in the rear of the user's torso. The longitudinally extending raised absorbent guide members 20 will then be positioned in the user's under garment to guide menstrual liquid overflow resulting from heavy flow towards the absorbent end member 22 and absorbent end member 28. As a result any leakage from the front and rear of the pad is contained.
This invention has been shown and described in what is considered to be the most practical and preferred embodiment. However, it should be recognized that changes may be made by those skilled in the art without departing from the spirit of the invention.
