EXAMPLES Next, examples will be described in which the present invention is applied to sanitary products. FIG. 1 shows a schematic view of the back of a sanitary article 1 that is folded in three. The sanitary product 1 itself is not different from the commercially available product. To fold the sanitary article 1 in three, as shown in FIG.
The left side portion 11 and the right side portion 12 of the sanitary product 1 are folded back along the fold line a and the second fold line b to the skin-facing side of the sanitary product 1, respectively. Here, the first broken line a means that the sanitary product 1 is divided into three equal parts.
Kino refers to the left of the fold on the left side from the left equal position, and the second fold line b, from right aliquoted position when 3 equally divided
The fold located on the right side .

As shown in FIG. 2, the film 2 has a width W.
Is about 5 to 25 mm shorter than the length of the sanitary article 1 in the longitudinal direction.
Wider than the circumference of the sanitary article 1 folded in three, which will be described later.
A band-shaped one that is wider than the glue application area is used. Then, it is usually preferable to use a roll that has been wound up, and successively draw it out and supply it to the packaging machine. Further, as the film 2, for example, a PE film, an ever poly film or the like is used. Then, the inner front surface of the film 2, i.e., the surface to be overlaid on the adhesive 3 that is applied to the outer surface of the sanitary product 1 is processed peelability. The releasability treatment is a treatment for imparting a property of temporarily adhering so that it can be lightly adhered when pressed against the glue surface, but can be easily peeled off by peeling it by hand. In order to perform the peeling treatment, the film is coated with silicon, dried and then 120 to 13
A known method such as applying heat of 0 ° C. or UV curing with ultraviolet rays can be arbitrarily adopted. The release of the process, depending on the material of the film 2 sometimes sufficiently performed at intervals need not be performed for the inner front surface entire range of the film 2.

The procedure for packaging the sanitary article 1 with the film 2 is as follows. First, glue 3 on the outer surface of the sanitary product 1 as shown in FIG. 1 (e.g., hot melt adhesive) is applied to. Here, the range in which the glue 3 is applied is a region between the left end of the sanitary product 1 and the first folding line a to the right end of the sanitary product 1 and the second folding line b . Therefore, where the second fold line b from the left side about 10~20mm the first fold line a
Adhesive is applied to the range on the right side of about 10 to 20 mm. Then, the method of applying the glue 3 includes a linear shape such as a double line or a triple line, spiraling, or sticking. The glue 3 is temporarily adhered to the underwear during use to prevent misalignment.

However, the right edge that is outside the area where glue 3 is applied is
Fold back to the right side of the sanitary product 1
Not not.

Next, as shown in FIGS. 3 and 4, the right side portion 22 of the film 2 and the right side portion 12 of the sanitary article 1 which are adhered and integrated by the glue 3 are floated from the sanitary article 1. folded underneath surface <br/> the left edge P of the film left side 21. Then, the left end of the left portion 21 of the film 2
Superimposing the edges 21a on the right edge 22a of the right side portion 22 of the film 2. In this case the hot-melt adhesive 4 to the left edge 21a of the film 2 and beat beating, or at heat sealing to bond the left end edge 21a on the right edge 22a of the film 2 to form an envelope-like film 5. Note that, although applying the glue 3 to the left edge 21a of the film 2 which has been floated from the sanitary article 1, the right side portion of the right side portion 12 and the film 2 of the sanitary product 1 in the second fold line b of sanitary product 1 22 after folded together, by the glue 3 is applied to the right edge 22a of the film 2
You may adhere .

Finally, the envelope- shaped film 5 is covered.

Sealed, further cut, sanitary products 6 sanitary product 1 is wrapped by the film 2 you completed. Wherein the ratio
Heat-sealing Examples of the method over preparative seal and cut, for example, across a rotating drum 8 and the rotary drum 10 of the upper strip-shaped film 5 which has been conveyed by the belt conveyor 7 with a heater 9 as shown in FIG. 5 There is a way to cut it.

By the above packaging method, the process of folding the sanitary article in three and the packaging process can be combined into one process.
It is possible to improve work efficiency. In addition, the film adhered to the back surface of the sanitary product can be used as a packaging bag while playing the role of release paper, so that effective use of resources can be achieved.

Next, a physiological product manufactured by the method for packaging a sanitary product will be described. As shown in FIG. 6, the sanitary product 6 manufactured by the packaging method is coated with glue from the left side of the first folding line to the right side of the second folding line on the back side, and the sanitary article folded in three is attached to the glue of the sanitary article on the back side. Is wrapped with glue or heat-sealed with a film that has been subjected to a peeling treatment, but since the film 2 is folded over the sanitary product 1, it is in close contact with the sanitary product 1 and there is no extra gap. Moreover, since there is no opening, even if it is a small part, the inside can be completely sealed. In this way, the product is hermetically packaged into a compact product, which is hygienic and convenient to carry.

Although the above-mentioned embodiment describes the sanitary article, a similar packaging method can be adopted for the panty liner to achieve hermetic packaging.
