Moreover, as shown to FIG. 4B, the adhering part 41 and the surface joining part 44 may mutually be temporarily fixed by temporary fixing agent H1.
In addition, a hot melt resin or an adhesive can be used as the temporary fixing agents H1 and H2. Further, the temporary fixing agents H1 and H2 are preferably provided at a plurality of locations in the corners of the web. However, in each drawing, only one location is shown for convenience of drawing.

Next, an example of a method for manufacturing the diaper will be described with reference to FIGS.
First, an example of a manufacturing method of the first joining member 4 will be described.

In FIG. 7, while a pair of continuous sheets S1 to be the base material 43 are conveyed in the longitudinal direction X1, a continuous fastener material F to be the male fastener 40 is welded and pasted on each continuous sheet S1. . Thereby, the continuous body S2 used as the said joining member 4 is produced | generated.

Next, each continuous body S2 is folded twice along a virtual fourth line (folding line) L4 extending in the longitudinal direction X1 of the continuous body S2 at a portion where the continuous fastener material F is not attached. It is done. As a result, as shown in FIGS. 2A and 2B, the non-fixed surface 412 opposite to the fixed surface 411 in the fixed portion 41 of the first bonding member 4 is opposite to the male surface fastener 40 in the surface bonded portion 44. The surface bonding portion 44 overlaps the fixing portion 41 such that the non-bonding surface 442 on the side faces each other.

The folded continuum S2 in FIG. 7 is cut along a virtual fifth line L5 orthogonal to the longitudinal direction X1, whereby the individual first joining members 4 are cut off from the continuum S2. . Thereby, a pair of 1st joining members 4 are produced | generated. The pair of first joining

members

4 and 4 are perpendicular to the longitudinal direction X1 so that the folding lines in the fourth line L4 are close to each other and the first joining

members

4 and 4 are not overlapped with each other. Moved to.

Each of the pair of first joining

members

4 and 4 is disposed on the non-skin surface 3b2 of the portion that becomes the

rear flaps

3B and 3B of the first continuous web W1 that forms the rear waistline portion after being turned by 90 °. At the same time, the fixing portion 41 is bonded and fixed to the first continuous web W1. Under the present circumstances, it arrange | positions so that the position between a pair of said

1st joining members

4 and 4 may become the position of the virtual 3rd line L3 of the 1st continuous web W1 cut | disconnected later.

Prior to the arrangement and fixing of the first joining

members

4 and 4, the non-joint surface 442 (FIG. 2B) of the first joining

members

4 and 4 is provided in the vicinity of the third line L3 of the first continuous web W1. A temporary fixing agent H1 for temporarily fixing to the non-skin surface 3b2 of the rear flap 3B is applied. Therefore, when the

first bonding members

4 and 4 are arranged and fixed, the non-bonding surface 442 (FIG. 2B) of the

first bonding members

4 and 4 is temporarily fixed to the non-skin surface 3b2 of the rear flap 3B.

The diaper main body 2 is constructed and fixed on the two webs W1 and W2 while the first and second continuous webs W1 and W2 serving as the front and rear waist portions are conveyed in the longitudinal direction X1. Thereby, the continuous laminated body W3 used as the diaper 1 is produced | generated (refer FIG. 2A and FIG. 2B).

The continuous laminated body W3 in FIG. 8 is a virtual parallel to the waistline direction X such that the first continuous web W1 and the second continuous web W2 overlap each other, that is, the front portion 20 and the back portion 21 overlap each other. In the first line L1, the crotch portion 22 is folded twice (see FIGS. 3A and 3B).

A temporary fixing agent H2 for temporary fixing is applied to the rear flap 3B and / or the front flap 3F before the crotch portion 22 is folded or after the crotch portion 22 is folded.

As shown in FIG. 8, after the folding process of the diaper main body 2, the continuous laminated body W3 is cut along the virtual third line L3 at the portions of the continuous webs W1 and W2, and individual diapers 1 are separated. Cut from the continuous laminate W3.

After the separation, the front flap 3F and the rear flap 3B are folded at a virtual second line L2 extending in the longitudinal direction Y so that the pair of the rear flap 3B and the front flap 3F in FIG. 3A overlap the front portion 20. . The second line L2 is set at a position close to both edges E1 of the diaper main body 2. Further, the diaper 1 may be turned 90 ° immediately before folding both the

flaps

3F and 3B. Thus, the diaper 1 shown in FIGS. 4A and 4B is generated.

When the front and

rear flaps

3F and 3B are folded, the folded

flaps

3F and 3B are temporarily fixed to the front portion 20 by the temporary fixing agent H2. Thus, after the diaper 1 is folded into a compact state as shown in FIGS. 4A, 4B, and 5, it is packaged and shipped.

2A to 5 show the order of folding for packing the above diapers in units of one diaper.

Next, a procedure until the diaper 1 folded as shown in FIG. 5 is worn will be described.
In FIG. 5, when the user picks the surface joint portion 44 of the pair of first joining members 4 with fingers of both hands and pulls it in the directions of the arrows X2 and X2, the surface joint portion 44 temporarily fixed to the rear flap 3B is formed. While being peeled off from the rear flap 3B, the flap 3B (3F) which has been temporarily fixed to the diaper main body 2 is peeled off from the diaper main body 2.

Thus, as shown in FIG. 6A, the diaper 1 half-opened in a T shape appears. Thereafter, the user further opens the diaper 1 and causes the wearer to wear it in the form as shown in FIG. 6B.

In the packaged state of FIG. 5, a pair of male fasteners 40 appears on the outer surface. Therefore, the wearer who sees this form easily comes up with drawing out the male fastener 40 when using it for the first time. In addition, the producer can easily draw an explanatory diagram of the usage. Therefore, how to use diapers is easy to understand.

Hereinafter, another example of the present invention will be described.
In FIG. 9A to FIG. 14 below, the portion of the temporary fixing agent is indicated by a black circle.

As shown in FIGS. 9A to 9D, the first joining member 4 may be folded in a Z-shape in a triple manner. In this case, as shown in FIGS. 9A and 9B, the pair of first joining

members

4 and 4 are formed by joining the first member to the first continuous web W1, and then as shown in FIGS. 9C and 9D. At the time of cutting the continuous web W1, the first joining member 4 can be cut together with the first continuous web W1 to generate two first joining

members

4 and 4.

Further, the first joining member 4 does not necessarily need to be folded. As shown in FIGS. 10A to 10D, the first joining member 4 may be formed by bonding (welding) three base members 43 to each other.

In the packaged state, the first joining member 4 is not necessarily double. As shown in FIGS. 11A to 11D, for example, the first end members 43 of the base member 43 that are not folded are fixed to the

rear flaps

3B and 3B, and the first end members 43 are fixed to the second end portion 43b. You may have the hook-and-loop fastener 40. FIG.

In this case, in order to fix the first joining member 4 to the rear flap 3B, first, the joining piece 4A of FIG. 11A is arranged on the third line L3 so as to straddle the diapers adjacent to each other. At this time, the joining piece 4A is fixed to the first web W1 at the fixing portions 41 on both sides in the vicinity of the third line L3 in FIG. 11B.

After the fixing, the joining piece 4A is cut along the first web W1 along the third line L3 and separated into two. Thereby, the 1st joining member 4 is formed in each rear flap 3B.

This structure has an advantage that the base material 43 does not need to be folded. However, since the male fastener 40 is folded and used in the direction of the arrow R, a force is easily applied to the fixing portion 41 so that the fixing portion 41 of the first joining member 4 is easily peeled off.

In the example shown in FIG. 12, the waistline member forming the rear flap 3B and the front flap 3F is attached to the skin surface side of the diaper main body 2.

In the example shown in FIG. 13, the flaps 3 </ b> B and 3 </ b> F are fixed to the end of the diaper main body 2 in the waistline direction X. In this case, the laminated body W4 which comprises the diaper main body 2 may be continuing in the vertical direction Y like the example shown in FIG.

As described above, the preferred embodiments have been described with reference to the drawings. However, those skilled in the art will readily understand various changes and modifications within the obvious scope by looking at the present specification.
For example, the diaper main body and the front and rear flaps may be formed of a continuous web. In this case, leg holes are formed in the web.

The first joining member may be fixed to the rear flap 3B after the diaper body 2 is installed between the first and second webs or after the continuous laminated body W3 is folded in two.
Accordingly, such changes and modifications are to be construed as within the scope of the present invention as defined by the claims.

The present invention can be applied to a disposable diaper packing structure and its manufacturing and folding method.
