  As shown in FIG. 4, the package of Patent Document 1 is serially arranged with the breast pad 10 folded in half in the same direction with respect to the central region of the container 20 that is long in a band shape in one direction. Two end regions 22 and 23 that are continuous with each other in the length direction with respect to the central region of the container are folded on the two breast pads so that two It consists of a breast milk pad.

  As shown in FIG. 8, the package of Patent Document 2 is a breast milk in which a main body 18 is formed by laminating an absorbent body 12 that absorbs liquid and a waterproof material 11 disposed outside the absorbent body. It is a container for housing the pad 10, and an adhesive part 4 is provided on the surface side of the waterproof material of the breast milk pad, and this adhesive part is in a state where the breast milk pad is accommodated in the container. Thus, it is temporarily fixed inside the container.

  As shown in FIG. 3, the packaging body of Patent Document 3 is a breast milk pad that forms a main body by laminating an absorbent body 12 that absorbs liquid and a waterproof material 11 disposed outside the absorbent body. Is a container 20 configured by sandwiching the breast milk pad between one strip-shaped member 21 and 22 above and below, and is folded in half between the top and bottom strip-shaped members. The two breast pads 10, 10 are arranged in a row in the same direction in the respective bent portions, and the upper and lower belt-shaped members are arranged along the peripheral edges 21a, 22a. Further, one of the band-shaped materials is provided with a perforation 24 along the width direction in a region between the two breast milk pads.

In the container described in the first patent document, both end regions 22 and 23 that are continuously provided in the length direction with respect to the central region of the container are folded on the breast milk pad, and the peripheral part is formed. Although it is joined, the central part is released, and it is only stopped by the fixing tape 26, so there is a drawback that the sealing performance is poor.
The container described in the second patent document and the container described in the third patent document are both sealed in the package (film), and the breast milk pad is taken out only by breaking the package. The former is mainly described for one breast milk pad and the latter for two breast milk pads.
However, these are intended to break the central part of the packaging film and take out the breastfeeding pad that is the contents, and in particular, the collection of two breastfeeding pads has the center of the strip-shaped film long in one direction. The work required to take out a breast milk pad of a predetermined size from a deep bag-like film, which was broken into lines, was inferior to usability.

  The present invention has been made to solve such a problem, and the film can be broken by simply opening the folded breast milk pad package, and one or two breast pads can be attached. It is an object of the present invention to provide a breast milk pad packaging body and a method for producing the same, and a packaging method for a breast milk pad that enables such a thing.

  In the first invention, the above object is obtained by folding the first sheet and the second sheet for forming the package body, and the first sheet and the second sheet. A first breast pad and a second breast pad accommodated in a row in between, and the outer peripheral edges of the first sheet and the second sheet are joined to each other; and In the joined state, the package body is folded in half between these areas so as to be divided into first and second areas in which the first and second breast milk pads are accommodated. Part of the sheet is fixed, and moreover, one sheet can be easily placed in the same direction as the folding line of the package body on the outer peripheral side from the position where the overlapping portion inside the first region is fixed. The fragile part was formed so that it could be broken That the milk pad packaging is achieved.

According to the configuration of the first invention, the first sheet and the second sheet for forming the package body are folded in half, and are arranged in a row between the first sheet and the second sheet. The first breast pad and the second breast pad accommodated side by side, and the outer peripheral edges of the first sheet and the second sheet are joined together, so that they are completely sealed A breast milk pad is accommodated in the bag. For this reason, there is no fear of moisture entering, and the product quality can be maintained satisfactorily.
The package body is folded in half between the first and second regions in which the first and second breast pads are accommodated, and the overlapping portion is fixed. Therefore, it can be kept compact as an individual package containing two breast milk pads.
In addition, a weakened portion is formed inside the first region so that one sheet can be easily broken in the same direction as the folding line of the package body. When the joint end portions of the first region and the second region are opened outward in the state, the force concentrates on the fragile portion, the fragile portion is broken, and the outer peripheral edge of the package body is further broken. The joint is broken and the breast milk pad accommodated inside can be taken out.
In other words, according to the present invention, the sheet can be broken only by opening the folded body of the breast pad package, and one or two breast pads can be easily taken out one after another. A breast milk pad package can be provided.

According to a second invention, in the configuration of the first invention, the first and second breast milk pads are arranged in a line in the same direction in the package body, whereby the package body is folded in half. In such a state, the first and second breast milk pads are alternately polymerized.

According to the configuration of the fourth invention, when the first region of the package body in the folded state is opened and the first breast milk pad accommodated is taken out, it is adhered to the first breast milk pad. Since the peeling member has a higher adhesive strength to the inner surface of the package body than the adhesive strength to the first breast pad itself, in the operation of taking out the first breast pad, the first The peeling member is detached from the breast milk pad side and remains adhered to the inner surface of the package body.
And since this peeling member is the state adhere | attached on the inner surface of the said package body so that the said 1st and 2nd sheet | seat may be straddled, the 1st area | region opened outside, 2nd The second region which contains the breast milk pad and has not been opened can be closed and held.
Furthermore, from this state, the weak part provided in the corresponding portion between the first and second sheets of the peeling member is broken by simply grabbing both ends of the peeling member and applying light force. A second region containing the second breast milk pad can be opened to expose the second breast milk pad.

  In addition, in the fifth invention, the above object is a method for producing a breast milk pad package, comprising: a pre-process for producing a breast milk pad; and a post-process for packaging the breast milk pad produced by the pre-process with a package. In the above, the pre-process is arranged between a molding step for molding an absorbent body for absorbing liquid, the molded absorbent body between a back sheet for preventing liquid from permeating and a liquid-permeable top sheet. Laminating step, step of adhering the top sheet and back sheet of the outer peripheral part of the product, folding step of folding in half so that the top sheet is inside, cutting into individual breast pads A first sheet body and a second sheet body, each of which is a long sheet body that is continuous in the length direction.

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
The embodiments described below are preferable specific examples of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention particularly limits the present invention in the following description. As long as there is no description of the effect, it is not restricted to these aspects.

First, an example of the breast milk pad used for the breast pad packaging body according to the embodiment of the present invention will be described.
FIG. 1 is a schematic perspective view seen from the outside of a breast milk pad, and FIG. 2 is a cross-sectional view taken along line AA of FIG.
A back sheet 11 is disposed outside the breast milk pad 10 shown in FIGS. 1 and 2 (on the upper surface side in FIG. 1), and on the inner surface side (lower surface side in FIG. 2) that contacts the user's skin when worn. The top sheet 13 is arranged.
An absorbent body 12 is disposed between the top sheet 13 and the back sheet 11, and the breast milk pad 10 is, for example, a substantially circular product as a whole.
This absorber 12 is preferably wrapped with tissue 15.
Further, an absorption diffusion layer (sublayer) 16 is provided just inside the top sheet 13 and outside the absorbent body 12 wrapped in the tissue 15.

  The back sheet 11 does not allow liquid to pass through, but it is preferable to select a material that can pass water vapor and prevent stuffiness and has some flexibility. Further, the back sheet 11 is formed of a flexible material as compared with a back sheet that can be thermally deformed conventionally. Examples of such a material include a resin film such as polyethylene, a sheet material obtained by laminating a nonwoven fabric on the outside of a resin film such as a polyethylene laminated nonwoven fabric, and a melt blown nonwoven fabric. For ease of use, it is preferable to use a laminate of a nonwoven fabric and a resin film.

  The top sheet 13 is a member that is in direct contact with the user's skin, and a material that is well permeable to moisture such as breast milk and has a good texture is selected. That is, since the top sheet 13 directly touches the skin of the user, a material suitable for this is selected in consideration of the good touch without damaging the skin more than necessary. Preferably, a dry mesh sheet (a mesh sheet formed of polyethylene or the like) or a non-woven fabric made of natural fibers such as rayon or resin fibers such as polyethylene is used. It is preferable to use a nonwoven fabric mixed with heat-fusible fibers.

For the absorbent body 12, a material excellent in liquid absorbency is selected. For example, a pulp fiber body, a laminated body, a sheet body, or the like is used. Further, the absorbent body 12 is preferably mixed with a polymer 14 which is a granular material made of a material having excellent liquid absorbability and having a function of holding the liquid as it is or semi-solidified or solidified. .
As such a material for constituting the polymer 14, for example, a water-absorbing polymer is suitable. For example, a polyacrylate copolymer, a hydrolyzate of starch-acrylonitrile graft copolymer, starch-acrylic. Examples include acid graft copolymers, polyvinyl alcohol-acrylate copolymers, and carboxymethyl cellulose modified products.
The absorber 12 is wrapped in the tissue 15. This prevents the granular polymer and the like from leaking out.

The central portion of the absorbent body 12 covered with the tissue 15 is a thick portion 12a formed so as to have a thickness, and is configured so as to have a soft feel by increasing cushioning properties associated with contact with the nipple. . Moreover, the outer peripheral part of the absorber 12 is made into the thin part 12b formed thinly, and it is comprised so that a breast may be fitted. At this time, the thick portion 12a is formed in a curved shape so that the height increases toward the center.
Here, after wrapping with the tissue 15, the thin portion 12 b is compressed more strongly than the thick portion 12 a to form a difference in thickness, but the thick portion 12 a may be laminated and formed.
The absorption diffusion layer 16 is disposed at a position corresponding to the nipple at the substantially central portion of the absorber 12. And since the density is made coarser than that of the absorber 12, the initial absorption speed of the liquid is high and the material is excellent in diffusibility, and since the density is coarse, it has cushioning properties. Preferably, the fiber having a lower water absorption than the absorbent body 12 is made bulky by using polyethylene, polyester, polypropylene, etc. having a thickness of about 2.2 decitex to 7.7 decitex alone or in combination. Non-woven fabrics, continuous foamed sponge bodies, and the like can be used.

  Temporary adhesive portions 19 and 19 that can be temporarily fixed to underwear such as a bra worn by the user are provided on the upper and lower sides of the back sheet 11 of the breast milk pad 10. In the temporary bonding portions 19 and 19, a peeling member is further fixed on the adhesive. Although the material of a peeling member is not restricted, For example, the peeling paper which is a paper-made peeling member by which the process which can be peeled easily can be used. In this embodiment, the release paper 18 is stuck to or pasted on the temporary bonding portion 19 via an adhesive described later.

Further, the joints 21 and 21 are formed at positions opposite to each other near the outer edge of the breast milk pad 10 or symmetrical to each other with respect to the center of the circular shape, so that the bowl is almost dome-shaped as a whole. The form is formed.
The joint portions 21 and 21 are formed as follows.
For example, in a structure in which the circular absorbent body 12 is sandwiched between the top sheet 13 and the back sheet 11, notches are formed only for the absorbent body 12 from positions facing each other on the outer periphery. This notch is a substantially triangular notch that is reduced inwardly. At this time, the top sheet 13 and the back sheet 11 do not form a notch. In the region where the notch is formed in the absorber 12, the back sheet 11 and the top sheet 13 are partially overlapped. Then, the whole is folded in two along a virtual center line 23 connecting the vertices of the notches, and the opposing top sheets are joined to each other in the notch region.

In such a configuration, in the portion corresponding to the joint portion 21, the thick portion 12a of the absorber 12 and the absorption diffusion layer 16 are not disposed, and only the top sheet 13 and the back sheet 11 are laminated. As a result, the entire breast milk pad 10 has a form in which the joints 21 and 21 at both ends are picked. As a result, the whole breast milk pad 10 has a substantially dome shape by the support force of the joints 21 and 21. Will form.
Preferably, the corners of the joints 21 and 21 are chamfered to form chamfers.

Such a breast milk pad 10 is manufactured by, for example, a method described later, and is packaged and accommodated in a package body. Hereinafter, an embodiment of a method for producing a breast milk pad package as a product in which the breast milk pad is housed in a package will be described.

Next, as shown in FIG. 3 (b), an adhesive may be applied to the surface of the release paper material 31 at a substantially symmetrical position with the perforation 32 interposed therebetween, and then applied to the breast milk pad. Adhesive portions 34, 34 are formed as possible. The adhesive portions 34 and 34 are prevented from being displaced, and are formed, for example, by applying a hot melt adhesive.
Subsequently, as shown in FIG. 3C, the release papers 18-1 and 18-2 are cut and separated from the release paper member 31 one by one.

Then, FIG. 4 has shown the process of sticking the release papers 18-1 and 18-2 on the strip-shaped material 11-1 for forming the back sheet 11.
Here, the strip-shaped material 11-1 for forming the back sheet is specifically a sheet material obtained by laminating a nonwoven fabric on the outside of a resin film such as polyethylene or a resin film such as polyethylene laminated nonwoven fabric, or a melt blow production method. It can be formed of a nonwoven fabric or the like. In the manufacturing process, a strip-shaped material 11-1 for forming a back sheet made of such a material is sent from a supply roll (not shown) and sent in the transport direction.
On one surface of the strip-shaped material 11-1 for forming such a back sheet, release papers 18-1 and 18-2 are sequentially attached in accordance with the interval between the breast milk pads accommodated in the package body.

FIG. 5 shows a state in which the strip-shaped material 13-1 for forming the top sheet 13 is arranged on the state of FIG. 4, and in the manufacturing process, the strip-shaped material 13-1 for forming the top sheet is shown. Is also sent from a supply roll (not shown). Specifically, the belt-like material 13-1 for forming the top sheet is a nonwoven fabric made of natural fibers such as dry mesh sheets or rayon, which are mesh-like sheets made of polyethylene or the like, resin fibers such as polyethylene, or the like. For example, a heat-fusible fiber is mixed.
Here, the above-described laminating process is performed so that the belt-like material 13-1 for forming the top sheet and the belt-like material 11-1 for forming the back sheet have the following positional relationship. That is, it fixes in the state which pinched | interposed the absorber 12 covered with the tissue 15 with the surface where the release paper of the back sheet 11 is not affixed, and the top sheet 13. Thereby, the strip-shaped material 13-1 for forming the top sheet and the strip-shaped material 11-1 for forming the back sheet to which the release paper is attached are stacked with the absorbent body 12 covered with the tissue 15 interposed therebetween. It becomes one continuous belt-like material 33.
In addition, the area | region shown with the dotted line 30 has shown the area | region cut as a breast milk pad which is a product in the process after this.
The outer region of the dotted line 30 is bonded.

Moreover, the release paper 18-1 is affixed in the position shown in FIG. That is, the position of the perforation 32 that is the fragile part of the release paper 18-1 and the fold line part 23 (virtual center line) that folds the breast milk pad are pasted at a shifted position so as not to overlap. Show.
(Folding process)
Next, with respect to the laminated belt-like material 33, the folding material described in FIG. 1 is folded by means of material folding provided in the manufacturing process, for example, a folding plate, with the belt-like material 13-1 side serving as the top sheet facing inside.
