Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to diapers with diaper fasteners of the type that include adhesive tape for securing the ends of the tape to separate parts of the diaper to hold the diaper to an infant.

Tape fasteners of the type described above have been proposed that include a piece of tape and a release sheet adhered to the center of the piece of tape having an exposed surface treated to be releasable to the adhesive.

One end of the tape strip is folded back against the exposed surface, thereby holding the fastener in the folded configuration and removing the adhesive on the end of the tape strip without the need for a separate release sheet. It protects them.

The object of the invention is to improve a fastener of the above-mentioned type which is easy to use, compact and aesthetically attractive when delivered to the consumer.

The present invention provides a diaper equipped with a fastener, in which the fastener has a tape piece coated with an adhesive on the entire surface of one side, and the tape piece includes a first part, a second part, and a second part adjacent to each other in the longitudinal direction. The first portion of the tape piece is adhered to the outer surface of the diaper body at a location adjacent to the side edge of the diaper body with the adhesive, and the adhesive-coated surface of the second portion has a A strip covering the second portion is adhered with the adhesive;
The surface of the strip opposite the second portion is releasable to the adhesive, the strip has a through opening, and the third portion of the tape is folded over the strip. a second portion of the tape piece, the third portion having a through opening that is aligned with a through opening in the strip when overlaid on the strip; a second portion of the tape piece; The adhered strip and the third portion of the tape folded over the strip are integrally folded back onto the inner surface of the diaper main body, and the strip and the third portion of the tape The diaper is fixed to the inner surface of the diaper body by the adhesive exposed through the through-opening.

The diaper of the present invention is convenient for packaging and other handling of the diaper because the tips of the fastening tape pieces do not freely protrude from the diaper body in the unused state delivered to the consumer.
Also, it has a sleek appearance.

Embodiments of the present invention will be described below with reference to the drawings.

Referring to the drawings, a disposable diaper 10 includes an outer water-impermeable plastic lining fabric 14 and an inner water-permeable outer fabric 16.
It consists of an absorbent body 12 sandwiched between.

The lining fabric 14 extends around the side edges 18 of the diaper and its flap portions 20 form part of the inner surface of the diaper.

A fastener 22 constructed in accordance with the present invention includes a tape piece 24 and a strip member 26.

Tape piece 24 is approximately three times as long as strip 26 and has adhesive applied to its entire surface 28 (i.e., the top surface as viewed in FIG. 3).

The first portion 30 of the tape piece 24 contacts the outer plastic surface of the diaper 10 near the side edge 18 and is secured with an adhesive.

The part 32 of the tape piece 24 lying below the strip 26 forms the second part of the tape piece 24 and the part 3 in the area of the side edge 18
Adjacent to 0.

A third portion 34 of the tape strip 24 extends from the end opposite the side edge 18 of the strip 26 (as viewed in FIG. 3) to the end of the tape strip 24.

The strip member 26 may be paper whose upper surface is treated with a release agent.

The strip 26 is provided with an opening 38 to expose the adhesive portion 40 of the tape section 32.

As best seen by contrasting FIGS. 2 and 3, portion 34 of tape strip 24 is provided with an aperture 42 which opens 38 when portion 34 is folded back into contact with surface 36.
Consistent with

As best seen in FIG. 2, when portion 34 is folded back to contact surface 36, openings 38 and 42 align and expose the adhesive in area 40.

Tape piece 24 can then be folded back around side edge 18 of diaper 10 to bring exposed area 40 of adhesive into contact with portion 20 of plastic backing 14 (FIG. 1A).

The adhesive in area 40 thus serves to hold fastener 22 in a compact, aesthetically appealing configuration prior to use.

Furthermore, the above-mentioned form of the fastener is convenient for automatic packaging of diapers since it does not use a tape with a freely protruding tip.

When the diaper is applied to the infant, the folded portion of the fastener overlying the inner surface of the diaper can be easily peeled away from portion 20 of the plastic backing 14 to form the configuration shown in FIG.

Although the adhesive used strongly adheres to the plastic backing fabric 14,
Area 40 is made small enough to allow for easy peeling by the consumer and to provide sufficient adhesion to hold the fastener in the configuration of FIG. 1 during normal pre-use handling.

Finally, the portion 34 of the tape strip 24 can be peeled off from the surface 36 of the strip 26 to obtain the configuration shown in FIG.

In the configuration shown in FIG. 3, the exposed adhesive in area 34 of tape strip 24 is used to secure the diaper to the infant, and the exposed surface 36 of strip 26 covers the adhesive in tape strip 24. Provides non-adhesive parts.

This last feature, of course, ensures that the adhesive of the fasteners 22 never comes into contact with the infant's skin, even if the diaper is misfitted or is pulled or twisted during use.
