Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to absorbent articles and disposable diapers.

In recent years, disposable diapers have become widely used.

Such diapers generally have a fluid-impermeable back sheet, a fluid-permeable front sheet, and an absorbent pad inserted between the sheets. Disposable diapers have become quite popular because they are discarded after one use and do not require washing, but there are difficulties in disposing of used diapers. For example, during a car trip, it is not possible to just throw away dirty diapers. Furthermore, even at home, it is troublesome or unhygienic to throw away diapers. It was suggested that the back sheet of the soiled diaper be removed and the remaining portion of the diaper be disposed of in a flush toilet. However, the conventional front sheet is strong enough even when wet to prevent it from tearing during use, so if the diaper is flushed through a flush toilet, it may cause damage to sewage treatment equipment, such as septic tanks. . Therefore, soiled diapers are typically disposed of temporarily in a waste bin and then permanently disposed of through other waste disposal systems. Although putting it in a garbage container is temporary, it is clear that this method of disposal is unhygienic. Also, there is a feeling of reluctance to handle dirty disposable diapers by hand. A first feature of the present invention is to provide an absorbent article and disposable diaper of simple construction that can be handled and disposed of in a hygienic and convenient manner after use.

The absorbent articles and diapers of the present invention consist of a pair of waist, absorbent pad assemblies having multiple edges.

The absorbent article and the diaper are provided with a disposal bag having a bag portion and a gate communicating with the bag portion. The bag has a compact shape and is located at one of the waists of the pad assembly. Thus, one feature of the present invention is to deploy the bag to place the soiled absorbent article or diaper in the bag after use.

Another feature of the invention is that it is possible to dispose of soiled absorbent articles or bags containing diapers in a hygienic manner.

Yet another feature of the invention is to reach into the bag portion of the bag, grasp the soiled absorbent article or diaper through the bag, and then turn the bag over to access the soiled absorbent article or diaper. This means that you can easily slip it into your bag.

A feature of the invention is therefore that soiled absorbent articles or diapers can be placed into the bag in a simple and hygienic manner.

Another feature of the invention is that, in one embodiment, the ends of the absorbent article or diaper cover the compact shaped bag during use of the absorbent article or diaper.

A further feature of the present invention is that the pouch portion of the bag is provided with securing means for closing the doorway of the bag after the bag is turned over and a soiled absorbent article or diaper is placed therein.

Embodiments of the present invention will be described in detail below with reference to the drawings regarding disposable diapers.

Now, looking at FIGS. 1 and 2, we see that the absorbent pad assembly 2
A flat diaper 26 having a diameter of 7 is shown.

The pad assembly 27 includes a fluid-impermeable front sheet 28 forming a back surface 30 of the pad assembly, a fluid-impermeable front sheet 32 forming most of the front surface of the pad assembly, the back sheet and the front side. Absorbent pad 36 inserted between the seat and the
, has front and rear waist portions 33a, 33b and a straddle portion 35 between the two waist portions. The diaper, and therefore the pad assembly, has a pair of side edges 38a, 38b and a pair of edges 40a, 40b connecting the side edges. The diaper 26 also includes a pair of conventional tape fasteners 42 near one edge 40b of the pad assembly, the attachment portions 43 of which extend beyond the side edges 38a, 38b of the pad assembly. used for securing to infants. As best shown in FIG. 2, the front sheet 32 and back sheet 28 extend to the edges of the diaper. The flat diaper 26 of FIG. 1 has multiple layers folded along vertical fold lines 44a, 44b, 44c, and 44d to form a box pleat configuration as shown in FIG.

As shown in FIGS. 1 and 3, the box pleat diaper 26 includes a vertically extending central panel C, a pair of first panels B connected to and overlapping the central panel, and and a pair of outer panels A and E connected to and overlying the first panel. The pleats 46 of the box pleat diaper may be separated at the lateral center of the diaper, as shown in FIG. 3, for purposes described below. The outer panels A and E can be moved laterally at the waist portions 33a, 33b of the pad assembly to unfold the pleats laterally. As shown in FIGS. 2 to 4, the box pleat diaper 26 has a flap 4 adjacent to the edge 40a.
8, the flap is folded back over the outer side 34 of the diaper along transverse fold lines 50 so that the outer side 34 of the flap 48 overlaps the outer side 34 of the diaper.

Preferably, the edge 52 of the absorbent pad 36 is spaced from the edge 40a of the diaper and is aligned with the fold line 50 of the flap 48.
is located near the edge 52 of the absorbent pad 36 so that the back sheet 28 of the flap overlaps the end of the absorbent pad that is folded back to the front side of the diaper. As shown in FIG.
and has a disposal bag 53 on the front surface 34 of E.

As shown in FIG. 14, the disposal bag 53 has a side edge 57a.
, 57b and 57c, and defines a pouch 59 therebetween. The bag has at its longitudinal end 62 an opening 61 leading into the pouch 59. Vertically extending sides 6 of the bag
3a and 63b are folded along the vertical folding lines 65a and 65b and stacked on the center portion 67 to make the lateral dimensions of the bag compact. After the bag is folded as described above, the bag is further compacted into the shape shown in FIG. Of course, if necessary, the vertical dimensions can also be made compact by other suitable means, such as folding. The bag 53, thus compacted in shape, is placed on the outer panels A and E near the fold line 50. A fastening means 54, such as an adhesive, is provided to keep the outer surface 34 of the diaper or flap 48 flush with the outer surface 34 of the box-pleated diaper.

For convenience, we will explain the case where adhesive is used as the fixing means 54, but it goes without saying that the front surface of the flap can be fixed to the front surface of the diaper using other suitable fixing means, such as heat sealing. . The fixing means 54 is attached to the center panel C.
and a pair of lines or points 58 of adhesive on the front surfaces of outer panels A and E; The bag 53 is placed intermediate the fixing means 54 and the fold line 50. The adhesive dot 56 is attached to the front surface 34 of the central panel C of the flap 48.
is fixed to the front surface 34 of the center panel C of the diaper. Similarly, lines of adhesive 58 are attached to outer panels A and E of flap 48.
The front surface 34 of the diaper is secured to the overlapping portion of the outer panel of the diaper. After folding the flaps 48 over the front surfaces of the bag and the diaper as shown by the arrows in FIG. It sticks.Therefore, the fifth
As shown in the figure, when the flap 48 is secured to the front surface of the diaper, the compacted waste bag 53 is captured under the flap 48 by the securing means 54. For convenience, the bag 53 is described as being attached to one waist 338 of the diaper, but it is clear that the bag could be placed on the other waist 33b as desired. The method of using the waste bag 53 with the flap 48 will now be described.

As shown in FIGS. 6 and 7, pleated diaper 26
When the near end of the flap 48 is unfolded to apply the diaper to the infant, the adhesives 56, 58, i.e., the fixing means 64, keep the front surface of the flap 48 attached to the front surface 34 of the diaper below. The bag 53 is maintained in position under the flap 48. Therefore, when the outer panels A and E are unfolded outwardly, the outer panel of the flap 48 is unfolded from below the center panel C of the flap 48, and the outer panel of the diaper underneath is unfolded from below the bag 53; 7
The bag is attached to the flap 4 by adhesive 56 as shown.
It is held in position below 8. When the end of the diaper is fully unfolded, the securing means 54 maintains the entire length of the flap 48 overlapping the portion of the diaper proximate the flap 48.
In this configuration of the diaper, the adhesive dot 56 is attached to the flap 48.
The center panel C of the diaper is held over the overlapping portion of the center panel of the diaper and the bag is held in place under the flap 48, while the line of adhesive 58 connects the outer panel of the flap 48 to the pad assembly. on top of the outer panel. As shown, the flap 48 covers the disposal bag 53 and prevents the bag from contacting the infant's skin during use. As shown in FIG. 8, after the diaper is used and removed from the infant, the flap 48 is attached to the
