Sanitary napkins having flaps extending outwardly from the longitudinal side margins are well known in the art. For example, U.S. Pat. No. 4,589,876 issued May 20, 1986, to Van Tilburg and U.S. Pat. No. 4,687,478 issued Aug. 18, 1987, to Van Tilburg disclose preferred sanitary napkins with flaps and are incorporated herein by reference to illustrate particularly preferred flapped sanitary napkin constructions.
To conserve space during packaging, i.e., the period between manufacture of the sanitary napkin and its intended first use by the wearer, the flaps of such sanitary napkins are typically folded to overlay the backsheet. At the time of the first use by the wearer, the flaps are usually unfolded to facilitate installation of the sanitary napkin into the wearer's undergarment. Typically adhesive, interposed between the backsheet and the flap adhesive release paper, is used for maintaining the flaps in the folded disposition prior to the wearer's first use of the sanitary napkin.
Several attempts have been made to provide alternative means for maintaining the flaps in the desired disposition prior to first use of the sanitary napkin by the wearer. For example, U.S. Pat. No. 4,759,754 issued Jul. 26, 1988, to Korpman discloses an adhesive tab which can be used for maintaining the flaps in the desired disposition overlaying the backsheet during packaging. U.S. Pat. No. 4,701,178 issued Oct. 20, 1987, to Glaug et al. discloses a sanitary napkin having a single release strip which covers the centrally located adhesive of the backsheet and over which release strip the flaps are folded.
One successful alternative to maintaining the flaps in the desired position prior to first use is shown in U.S. Pat. No. 5,800,654 issued Sep. 1, 1998 to Davis et al., which is hereby incorporated herein by reference. Davis et al. teaches a sanitary napkin packaged with flaps folded over to the topsheet and a unitary release strip bridging the adhesive of the flaps. As such, the user can first place the sanitary napkin in the crotch area of her undergarment by use of a central adhesive provided. She then simply peels off the unitary release strip bridging the folded flaps and folds the flaps back and around the edges of the crotch of her undergarment.
Not only does the Davis et al. packaging configuration maintain the flaps in the desired position prior to use, it also maintains the clean, sanitary condition and appearance of the sanitary napkin's body contacting sheet. This is important because the user is typically concerned with such cleanliness. This concern for cleanliness extends to more than just the sanitary napkin itself. The user of such a sanitary napkin often finds it necessary or desirable to clean the area of the anatomy associated with the wearing of a sanitary napkin. For example, when changing a sanitary napkin, the user may wish to wipe the vaginal area with a suitable cleaning implement, such as a cloth, or a wipe article such as a disposable towelette.
Several attempts have been made at providing a disposable wipe with a sanitary napkin. For example, U.S. Pat. No. 5,569,230 issued Oct. 29, 1996 to Fisher et al., which is hereby incorporated by reference herein, discloses an individually packaged sanitary napkin having a cleansing wipe packaged therewith. The wipe can be packaged in flaps located on various different portions of the wrapper. However, this configuration has certain drawbacks when the sanitary napkin is not configured for individual packaging. Also, the cost of providing such extra wrapper material, as well as the associated processing can be prohibitive for commercially viable products.
Other attempts have been made at providing a pre-wrapped moistened towelette with a sanitary napkin. For example, U.S. Pat. No. 4,848,572 issued Jul. 18, 1989 to Herrera teaches a towelette hermetically sealed in an elongate sheath releasably attached to an impermeable member of the sanitary napkin. However, the configuration shown requires the addition of significant material and components be added to the sanitary napkin. Also, the user must remove and use the wipe prior to placing the sanitary napkin for use in her undergarment, thereby causing inconvenience, and making the entire process rather awkward at a time when both ease of use and discreteness are appreciated.
Because of the sensitive nature of changing sanitary napkins, often under less than ideal circumstances, such as in public restrooms, it is desirable to provide a wipe for use with a sanitary napkin that is simple and convenient to use.
Furthermore, it is desirable to provide the wipe for use with a sanitary napkin in a commercially viable manner, that is, in a manner that does not cause the product to be cost prohibitive to market.
Additionally, it is desirable to provide a sanitary napkin having a flap disposition which promotes the cleanliness of the topsheet of the sanitary napkin during packaging and handling by the wearer prior to the first use of the sanitary napkin, and provides means for the user to conveniently and easily use a wipe article, if desired.
Finally, it is desirable to provide a convenient means for manipulating the flaps from the packaged arrangement to the disposition which the flaps will be used during wear, and to be provided with a vaginal wipe, which does not inconvenience the user by introducing additional time-consuming steps.
