  • Patent number: 4808175
    Abstract: A disposable diaper is combined with a reversible bag provided with coactive sealing members bordering and tightly sealing its otherwise open entrance mouth and protectively containing one or more wet wipe pads for use in cleaning an infant following soiling of the diaper. The bag is attached to one panel face of the diaper, either to or as the usual moisture proof backing for the diaper, and is reversible to encompass the soiled diaper and wet wipe pad or pads after use and bundling together. The coactive sealing members are reversibly arranged for ultimately sealing the bag against release of odor. Double tongue members back-to-back on a flexible plastic sheet to be connected to a second plastic sheet provided with tongue-receiving groove members back-to-back constitute an aspect of the invention having broad areas of use.
