Abstract

PROBLEM TO BE SOLVED: To compactly, individually and accurately package a sanitary product which has simplicity for opening and a side wing section without requiring a separate peeling sheet. SOLUTION: A cover sheet 3 wider in width than a sanitary product 1 is superimposed on the outer face of the sanitary product 1. The sanitary product 1 is folded inward into three from both ends in the longitudinal direction together with a cover sheet 3 along folding lines 4 perpendicular to the longitudinal direction. The sides of the cover sheet 3 are sealed 6 respectively, then both sealed side sections are folded to the outer face side of the cover sheet 3 and are stuck by not melt.

2. Description of the Related Art Hitherto, a sanitary product comprising a water-permeable top sheet and a water-impermeable back sheet formed in an envelope shape by sealing the peripheral edge thereof, and a bodily fluid absorber disposed between the two sheets are known. It is. The water-permeable topsheet is made of a material such as a nonwoven fabric that gives a comfortable feeling of adhesion to the wearer's skin, and can transmit bodily fluid discharged to the surface and move it to the internal bodily fluid absorber. The back sheet is formed of a resin sheet of polyethylene ad that can prevent the absorbed body fluid from leaking, and has an outer surface coated with an adhesive or the like for attaching sanitary products to underwear. The outer surface of the sanitary product is covered with a releasable cover sheet to protect the pressure-sensitive adhesive and the like applied to the outer surface of the back sheet and individually wrap the sanitary product. The cover sheet is made of a thin and flexible resin film such as polyethylene or polypropylene, and has a size slightly larger than that of a sanitary product so as to wrap the sanitary product.

[0003] A sanitary product is folded together with a cover sheet along a fold curve perpendicular to the length direction into three or four folds to fold into a small size, and a plurality of them are packed in a box or bag, or individually. The storage space does not increase when carrying. Several proposals have been made for individual packaging of such sanitary products. However, when individually packing a sanitary product having a wing portion on the side, there is a problem that the opening workability is poor because a release paper is separately attached to the wing portion.

[0004]

SUMMARY OF THE INVENTION According to the present invention, sanitary products can be individually packaged in a compact manner, and at the same time, can be easily opened, and a wing portion is provided on the side without the need for a separate release paper. It is an object of the present invention to provide a method for individually packing a sanitary product, which can accurately package the sanitary product having the above.

[0005]

In order to solve the above-mentioned problems, the present invention adopts a method in which a cover sheet having a width wider than that of a sanitary product is laid on the outer surface of the sanitary product, and the fold is perpendicular to the longitudinal direction. Fold the sanitary product along the curve inward from both ends in the longitudinal direction together with the cover sheet, seal the sides of the cover sheet as three folds, fold both sealed side parts to the outer surface side of the cover sheet, and hot melt. It is characterized by fastening.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings. In the figure,
(1) shows a sanitary product packaged by the individual packaging method according to the present invention, in which a body fluid absorber is arranged between a water-permeable top sheet and a non-water-permeable back sheet. It is formed in a substantially rectangular envelope shape. The wings (2) extend outward at substantially the center of both sides in the longitudinal direction, but a sanitary product having no wings (2) may be used.

[0007] (3) is a cover sheet for individually packing the sanitary napkin (1), which is made of a thin and flexible resin film such as polyethylene or polypropylene.
It is formed in a rectangular shape with a slightly wider width and a slightly shorter length and encloses the sanitary product (1). Wing section of sanitary products (1)
On the outer surface of (2) and, if necessary, the outer surface of the backsheet,
An adhesive for fixing the sanitary product (1) to the underwear is applied, and the cover sheet (3) is peelably adhered as a protective sheet of the adhesive. In addition, such a cover sheet
The structure of the sanitary product including (3) is conventionally known, and the configurations and materials of the top sheet, the back sheet, the body fluid absorber and the cover sheet are not particularly limited, and may be any of conventionally known configurations and materials. There may be.

[0008] The present invention relates to a method of folding such a sanitary napkin (1) together with a cover sheet (3) for individual wrapping. Referring to FIG. 1, the present invention provides a sanitary product (1) and a cover sheet (3) in a longitudinal direction along two fold curves (5) orthogonal to the length direction of the cover sheet (3). Fold inward from both ends and fasten the tape as a tri-fold
After the folded state is maintained in (5), the sides of the cover sheet (3) folded in three are sealed (6) by heat fusion.

Subsequently, both sealed side portions are folded back to the outer surface side of the cover sheet (3) along a fold curve (7) extending in parallel with the side of the sanitary napkin (1), and the folded ends are hot melt ( At 8), it is fixed to the outer surface of the cover sheet (3).
It is desired that the hot melt (8) be of a bonding type that can be easily opened, but an adhesive type that can perform smooth opening by adjusting the amount of application can also be used. The intended purpose can be achieved by applying the hot melt (8) to the side side along the seal (6) as shown in FIG. 4, or to the position to receive the side. it can.

[0010] The fastening tape (5) is attached to a sanitary product.
This is performed before folding the side (1) into three and before sealing the side (6) to stabilize the three-fold state, and this fastening tape (5) functions as a handle at the time of opening, which will be described later, to improve the opening workability. Hope to improve, but side seal
After performing (6) or folding both sides, the fastening tape (5) may be attached, or the fastening tape may be used.
(5) can be omitted to simplify the packaging process.

The sanitary article (1) thus folded
Is completely wrapped in the cover sheet (3), and the wing section (2) is also covered and sealed with the cover sheet (3). However, since the three folds in the length direction are inside and the side folds are outside, the wrapping form is stably maintained only by folding the side and fixing with the hot melt (8). Since the seal (6) is not located at the edge of the folded state, the seal (6) is difficult to peel off during carrying or handling.

When opening, the fastening tape (5) is pinched and peeled off as shown in FIG. Subsequently, when the detached fixing tape (5) is pulled as it is, the hot melt (8) fixing the side is peeled off, so that the side part is opened to the outside with self-opening property. Then, when the fastening tape (5) is further pulled, the side seal (6) is peeled off and the sanitary napkin (1) inside is exposed, so that the sanitary napkin (1) is peeled off from the cover sheet (3). And can be easily taken out.
The peeled cover sheet (3) can be used to wrap and discard used sanitary products.

[0013]

According to the method for individually packing a sanitary product according to the present invention, a sanitary product having a wing portion can be wrapped in a compact and completely stable state only by using a cover sheet wider than the sanitary product. Therefore, there is no need to use a separate release paper or the like, and the cover sheet can be properly opened by pulling the exposed side of the tri-folded edge to expose and remove the sanitary products inside.
