Description

  The present invention relates to an individual packaging body for absorbent articles which is formed by folding an absorbent article together with a packaging material in a longitudinal direction and sealing a predetermined portion of the packaging material.

Conventionally, absorbent articles such as sanitary napkins and panty liners (orimono sheets) are folded together with packaging materials, individually packaged (individually packaged), and marketed. In addition, such an absorbent article is usually used by being fixed to an underwear such as shorts through an adhesive part. However, in the packaged state, such an adhesive part is covered with a release paper or the like for protection. Has been.
When using such an absorbent article, the absorbent article is peeled off from the packaging material, and the adhesive paper is exposed by peeling off the release paper or the like. Is fully expanded.
Therefore, especially in absorbent articles that are relatively long in the longitudinal direction of the wearer, when the absorbent article is held, if the rear end portion is held, the front end portion is suspended, and if the front end portion is held, the rear end portion is suspended downward. Thus, the absorbent article could not be easily fixed at an appropriate position such as shorts. For example, the sagging front and rear ends may unintentionally stick to improper sites, and in such a case, it may be necessary to remove them once and reapply them. Complicated work was required.

  Patent Document 1 describes a sanitary napkin in which left and right flaps folded in the width direction are bonded to a peeling strap, and a means for starting the removal of the peeling strip is provided on the peeling strap. However, also in this sanitary napkin, when fixing an absorbent article to shorts etc., since the whole is developed in the longitudinal direction, the operability at the time of fixing is not good.

Hereinafter, the present invention will be described based on preferred embodiments with reference to the drawings.
The individual package of the absorbent article as the first embodiment of the present invention is an individual package 10 of a sanitary napkin formed by individually packaging a sanitary napkin 1 with a packaging material 9 as shown in FIG. .
As shown in FIG. 2, the sanitary napkin 1 (hereinafter, also referred to as napkin 1) in the present embodiment includes a top sheet 2 constituting a skin contact surface, a back sheet 3 constituting a non-skin contact surface, and both of these. The liquid-retaining absorbent body 4 interposed between the sheets is provided, and has a substantially vertically long shape. The top sheet 2 is composed of a liquid-permeable central sheet 2a and water-repellent side sheets 2b and 2b joined in a partially overlapping manner on both the left and right sides thereof.
The napkin 1 is a front part A disposed at a position closer to the wearer's abdomen when worn, in order from one end part in the longitudinal direction toward the other end part, and an excretion part facing part disposed to face the liquid excretion part of the wearer. B and a rear portion C arranged at a position close to the wearer's back.

The napkin 1 has a main body 5 having a configuration in which a top sheet 2, an absorber 4 and a back sheet 3 are laminated in this order at the center in the width direction. It has a flap portion formed by the top sheet 2 and the back sheet 3 extending from the edge.
The flap part protrudes greatly outward in the width direction of the napkin 1 at the excretory part facing part B, whereby a pair of wing parts 6, 6 are formed on the left and right sides of the main body 5. In addition, the flap portion also protrudes outward in the width direction of the napkin 1 also at the rear portion C, whereby a pair of rear flap portions 7 and 7 are formed on both the left and right sides of the main body 5.

The wing part 6 has the wing part adhesion part 81 formed in the surface at the side of the back surface sheet 3 by the application of the adhesive. When the napkin 1 is fixed to the underwear such as shorts, the wing portion 6 is bent to the back sheet 3 side and is adhesively fixed to the non-skin facing surface of the underwear such as shorts via the wing portion adhesive portion 81. The rear flap part 7 has a rear adhesive part 82 formed on the surface on the back sheet 3 side by application of an adhesive. When the napkin 1 is fixed to the underwear such as shorts, the rear flap portion 7 is adhered to the skin-facing surface of the underwear such as shorts via the rear adhesive portion 82 in a state of being extended to the side of the main body 5. Fixed.
On the surface of the main body 5 on the back sheet 3 side, an adhesive is applied in a rectangular shape to form a main body adhesive portion 5a. The napkin 1 has a narrow space between the wing portion 6 and the rear flap portion 7 in the longitudinal direction.

The individual package 10 of the present embodiment is obtained, for example, as follows. First, as shown in FIG. 3, the napkin 1 is placed on the packaging material 9. The wing part 6 and the rear flap 7 are bent along the both side edges of the main body 5 to the surface sheet 2 side (skin contact surface side) of the main body 5. Then, the rectangular release sheet 12 is placed on both the wing parts 6 and 6 so that the respective wing part adhesive parts 81 in the left and right wing parts 6 and 6 are covered. The release sheet 12 and the packaging material 9 are not joined even in part. The release sheet 12 is disposed in a region extending from the excretory part facing part B to the front part A of the napkin 1. That is, the release sheet 12 exists not only in the wing portion 6 but also in a portion indicated by F in FIG.

  In this state, the napkin 1 is bent in the longitudinal direction together with the packaging material 9 at a position slightly closer to the rear end than the boundary between the wing 6 and the rear flap 7. That is, a portion indicated by D in FIG. 3 in the vicinity of the rear end portion of the napkin 1 is bent toward the top sheet 2 side and laminated on a portion indicated by E in the drawing located on the front side of the napkin with respect to the portion. This bending is performed so that the rear adhesive portion 82 overlaps the release sheet 12. The folding line at this time is indicated by L1 in FIG. By this first bending, a portion indicated by D in FIG. 3, which is a portion located behind the wing portion 6, is superimposed on the portion E1 having the wing portions 6 and 6 in the longitudinal direction of the napkin 1. In the present napkin 1, the excretory part facing part B and the part E <b> 1 having the wing parts 6 and 6 in the longitudinal direction of the napkin 1 substantially coincide with each other.

  Next, the napkin 1 is bent in the longitudinal direction together with the packaging material 9 in the vicinity of the boundary between the excretory part facing part B and the front part A. That is, on the portion indicated by D in FIG. 3 in a state where the portion indicated by F in FIG. 3 which is a portion positioned in front of the wing portion 6 is folded to the surface sheet 2 side and overlapped on the portion E1 having the wing portion 6. Laminate to. Therefore, the release sheet 12 is also folded together with the portion indicated by F of the napkin 1. The folding line at this time is indicated by L2 in FIG. In this way, the napkin 1 is folded in the longitudinal direction together with the packaging material 9 to form a compact form.

  And while sealing both the side parts of the packaging material 9 extended in the width direction outward from the both-sides edge of the napkin 1 of the folded state by well-known joining methods, such as embossing, the edge part of the packaging material 9 is used. By fastening a known tab tape 11 at a predetermined location, an individual package 10 of the napkin 1 as shown in FIG. 1 is obtained.

  In the individual packaging body of the napkin of the present embodiment thus obtained, the back sheet 3 side surface of each wing part 6 and the back sheet 3 side surface (non-skin contact surface side) of each rear flap part 7 Are attached to the release sheet 12 in a detachable manner via the wing adhesive portion 81 or the rear adhesive portion 82 provided respectively. In addition, in the individual package 10 of this embodiment, the wing part adhesion part 81 or the rear part adhesion part 82 has mutually overlapped via the peeling sheet 12. FIG. That is, the wing adhesive portion 81 and the rear adhesive portion 82 are formed in substantially the same size at the same position in the width direction of the napkin 1 and at the same distance from the fold line indicated by L1 in FIG. ing.

  The skin contact surface of the main body is the surface of the main body that faces the wearer's skin when worn, and the non-skin contact surface of the main body is the underwear side of the body such as shorts when worn. It is a surface directed to the side opposite to the wearer's skin. The surface on the non-skin contact surface side of each of the wing portion and the rear flap portion is a surface facing in the same direction as the non-skin contact surface of the main body in a state where the absorbent article is expanded flat as shown in FIG. is there.

As the adhesive for forming the wing part adhesive part 81 and the rear adhesive part 82, various adhesives conventionally used for forming an adhesive part of an absorbent article such as a sanitary napkin can be used without particular limitation. The type of the adhesive may be the same or different between the wing adhesive part 81 and the rear adhesive part 82.
As the release sheet 12, various types that can be attached to the wing portion adhesive portion 81 or the rear adhesive portion 82 so as to be peelable can be used. For example, the release treatment is performed on both surfaces of a base sheet made of paper or a resin film. What was given can be used. For example, a release treatment such as a silicon resin, a fluorine resin, or an ethylene tetrafluoride resin may be applied or sprayed to form a thin film on the surface. A method of stabilizing the release coating by heat treatment can be exemplified. Further, by using a base sheet having a water-disintegrating function, a release sheet having no use such as wrapping a used napkin after fixing the napkin to an underwear such as shorts can be discarded in a toilet. As the base sheet having water decomposability, water-soluble polyvinyl acetate (PVA) resin or various water dispersible papers that can be dispersed in water can be used. In addition, it is preferable to use what made the collapse | disintegration of a sheet | seat easy to occur by carrying out the peeling process to the base material sheet | seat which has water decomposability | degradability by performing partially like a dot shape or a block shape, and also forming with PVA resin.
