Description

[Detailed Description of the Invention] The present invention relates to a diaper cover in which a cover body is formed of a double covering material, an inner covering material and an outer covering material.

An essential function of a diaper cover is leak-proofing, but this leak-proofing is not only to prevent urine fluid from leaking from the inner side of the diaper cover, that is, the side where the diaper is applied, to the opposite side. This includes a function to prevent so-called side leakage, in which urine fluid, etc. that has accumulated on the inner surface of the diaper cover flows along the inner surface and leaks out from the crotch portion of the diaper cover. By the way, a diaper cover made of a normal double-layered inner and outer covering made of waterproof fabric has sufficient protection against leakage from the inner side of the cover to the outer side, but it is difficult to prevent side leakage as described above. It is not particularly effective against Therefore, in order to prevent such lateral leakage in diaper covers made of double-layered materials, rising pieces for leakage prevention have conventionally been provided at both left and right ends of the crotch part of the inner covering material. Conventionally, when providing a crotch part, the stand-up piece was sewn along the crotch part of the inner covering material, so the stand-up piece was present at an angle to the crotch part, thereby making it difficult for the child's crotch area to There were some inconveniences such as the fit of the crotch part becoming poor and urine water etc. leaking from the seams of the sewn part.

The main purpose of the present invention is to solve the above-mentioned disadvantages, and one embodiment thereof will be described below with reference to the drawings.

Figures 1A and 1B are developed views of the outer covering material 1 and the inner covering material 2, which are made of waterproof and stretchable fabric, respectively. 2 forms the diaper cover main body. In the figure, 1a and 2a are the respective buttocks of the outer covering material 1 and the inner covering material 2, 1b and 2b are the crotch parts, and 1
c and 2c are the front part, and the crotch part 2b of the inner covering material 2
is formed wider than the crotch part 1b of the outer covering material 1. 3 is a crotch hole formed along the side edge of the crotch part 1b of the outer covering material 1, and 4 is a crotch hole formed along the side edge of the crotch part 2b of the inner covering material 2. ,
A generally crescent-shaped gusset 5 as shown in FIG. Like the outer covering material 1 and the inner covering material 2, this gusset material 5 is made of waterproof and stretchable fabric. Also,
With the gussets 5, 5 interposed between the crotch part 3 of the outer covering material 1 and the crotch part 4 of the inner covering material 2, the width of the crotch part 2b of the inner covering material 2 is as shown in FIG. As is clear from A and B, the width is wider than the sum of the width of the crotch portion 1b of the outer covering material 1 and the corresponding width of the gussets 5, 5. In addition, these outer covering materials 1,
The inner covering material 2 and the gusset material 5 are made of, for example, a knitted fabric of synthetic fibers such as polyester fibers, which has been appropriately treated with water repellent or waterproof treatment.

Figure 2 shows a diaper cover body formed by the outer covering material 1, inner covering material 2, and gusset members 5, 5 shown in Fig. 1 A and B, and the required accessories such as ear pieces are attached to this. A developed view of the completed diaper cover as seen from the outer covering material 1 side is shown, and FIGS. 3, 4, and 5
The figure shows the configuration of this diaper cover when it is worn, using an overall perspective view, a side view, and a sectional view. To explain the procedure for manufacturing a diaper cover with reference to these figures, first, the outer covering material 1 and the inner covering material 2 are overlapped (in this state, both sides of the crotch part 2b of the inner covering material 2 are covered with the outer covering material). 1), each crescent into both the coverings 1 and 2 from between each leg opening 3 of the outer covering 1 and each crotch opening 4 of the inner covering 2. Insert the shaped gusset 5 in a state where it is vertically folded in half (there is no need to make a crease), and one side edge 5 of the crescent gusset 5.
a is sewn to the leg opening 3 of the outer covering material 1, and the other side edge 5b is sewn to the leg opening 4 of the inner covering material 2, thereby forming the leg opening of the outer covering material 1 including these sewn parts. Elastic hem wraps 6 and 7 are provided over the entire area of the leg portion 4 of the inner covering material 3 and the inner covering material 2, respectively. Furthermore, Figure 3~
As shown in FIG. 5, both ends 6a, 6b of the elastic hem 6 on the side of the sheathing material 1 are superimposed on and covered by the elastic hemlock 7 on the side of the sheathing material 2. In this way, the elastic edge wraps 6 and 7 are attached to the side edges 5 of the gusset 5.
By providing the diaper cover body along the leg openings 4 and 5 to which a and 5b are sewn, a more effective three-dimensional shape is provided to the diaper cover body, and good adhesion to the thighs of the wearer, such as an infant, is achieved. At the same time, as mentioned above, the width of the crotch part 2b of the inner covering material 2 is wider than the width of the crotch part 1b of the outer covering material 1, and this wide crotch part 2b exists inside the cover body, and the outer covering material 2 is wider than the width of the crotch part 1b of the outer covering material 1. Gussets 5, 5 are interposed between the crotch part 3 of the material 1 and the crotch part 4 of the inner covering material 2, and these gussets 5, 5 are provided in the width of the crotch part 1b of the outer covering material 1. 5 is wider than the width of the crotch part 2b of the inner cover material 1, so when the diaper cover is used, both sides of the wide crotch part 2b inevitably tend to stand up. As is clear from FIGS. 3 and 5, raised portions 8, 8 for leakage prevention are formed, and as a result, this crotch portion 2b has a boat-bottom shape.

While forming the leak-proof raised parts 8, 8 on both sides of the crotch part 2b of the inner covering material 2 as described above,
As shown in FIG. 2, the upper edges of the outer sheathing material 1 and the inner sheathing material 2, which are overlapped with each other, are sewn together by an elastic hemline 9 that is wider than the hems 6 and 7, and the lower end edges thereof are sewn together. A pair of left and right ear pieces 11, 1 each having a pile-like outer surface are attached to both sides of the upper end of the overlapping covering materials 1, 2, which are sewn together with a hem cloth 10.
1 are sutured and connected, and the intertwining fastening pieces 12 are attached to the required inner surface of one of the ear pieces 11, and the above-mentioned fastening pieces 12 are attached to both ends of the inner surface of the front part 2c of the inner covering 2. Similar intertwining fastening pieces 13, 13 are attached, so that when the diaper cover is folded into the used configuration as shown in FIGS.
The inner surface of the front part 2c of the inner covering material 2 overlaps the pile-shaped outer surface of the ear piece 11 and is secured by the fastening pieces 13 by the fastening pieces 13. Similarly, it is designed to be entangled and fastened.

As is clear from FIGS. 2 to 4, the elastic hemline 7 provided along the side edge of the crotch portion 2b of the inner covering material 2
The upper end extends beyond the area of this crotch part 2b to the ear piece 1.
It extends to the lower edge of 1.

As explained above, the diaper cover of this invention is
The crotch part of the inner covering material is formed wider than the crotch part of the outer covering material, and the gusset material is interposed and sewn between the crotch part of the inner covering material and the crotch part of the outer covering material. Each crotch part including the sewn part is covered with an elastic hem so that when the diaper cover is used, the crotch part of the inner material forms a leak-proof raised part on both sides thereof. Unlike the leak-tight raised part sewn separately as in conventional diaper covers, this leak-tight raised part does not form an angular shape with respect to the crotch part. Since both sides of the crotch part form a smooth curve from the middle part of the crotch part to form a natural raised part, the crotch part has a good fit against the crotch of a child when worn. Since there is no seam at the bottom of the leak-tight raised part unlike in the past, there is no risk of urine water, etc. leaking out, and it can function satisfactorily as a leak-tight raised part of the inner covering material. In particular, since the width of the crotch part of the outer covering material plus the width of each of the gussets is wider than the width of the crotch part of the inner covering material, the diaper cover can be folded into a three-dimensional shape. When used in the interior, both sides of the crotch part of the inner covering material are positively formed into a rising tendency, so that a leak-tight raised part is formed more reliably.
