Description

  The present invention relates to a packaging structure for absorbent articles.

For example, in the packaging bag disclosed in Patent Document 1, since the perforation that creates the opening is made from the side surface to the top surface, the packaging of the absorbent article is made along the perforation. The opening is made up to the top side. For this reason, as shown in FIGS. 13 (1) and (2), even if the outer surface 22 of the absorbent article 21 stored in a compressed state is provided with a hot-melt adhesive 26 for preventing slippage, When the friction between the articles 21 is small, it is easy to pull out the absorbent article 21 from the opening (not shown) in the shear direction. However, in such a packaging bag, as shown in FIG. 14 (1), an engaging portion 23 such as a hook tape is arranged on the exterior surface 22 of the absorbent article 21, and the absorbent articles 21 are engaged with each other. It is not considered to take out the absorbent article 21 in the stored state as it is. When such an absorbent article 21 is taken out so as to be pulled out in the shearing direction, as shown in FIG. 14 (2), the engaging portions 23 (23A) and 23 (23B) are caught with each other. The folded one side of the absorbent article 21 (21B) adjacent to the article 21 (21A) is also lifted. Therefore, the absorbent article 21A is very difficult to take out. In some cases, even the next absorbent article 21B engaged is pulled out.
Moreover, in the package having the opening, when the absorbent article is taken out so as to be peeled away from the opening, the opening is made to be biased toward the top surface, so that the absorbent article is peeled off one by one. It is not easy to take out. Furthermore, since the opening is made up to the top surface side, the opening becomes too large, and the second and subsequent absorbent articles are easily pulled out.

  A preferred embodiment of a packaging structure for absorbent articles according to the present invention will be described below with reference to FIG.

As shown in FIGS. 1 (1) to (3), an absorbent article packaging structure 10 according to the present invention is accommodated in a packaging bag 11 in which a plurality of absorbent articles 21 are compressed in parallel in two stages. ing.
The packaging bag 11 includes a front surface 111F and a rear surface 111B as front and rear surfaces 111, a left surface 112L as left and right side surfaces 112, a right surface 112R, a top surface 113T and a bottom surface 113B as top surfaces 113, and a gusset structure on the left and right side surfaces 112L and 112R. Have.
At the center of the top surface 113 </ b> T of the packaging bag 11, a hanger part 12 is arranged in the direction of the left and right side surfaces 112, and a hanger opening 13 is provided at the center of the hanger part 12.

  The absorbent article 21 is, for example, an incontinence pad, or may be a sanitary napkin, an incontinence liner, or the like, and is not limited to the incontinence pad. The absorbent article 21 includes an exterior surface 22 on the side opposite to the surface positioned on the skin side when worn, and is folded with the exterior surface 22 on the outside. The engaging portion 23 is disposed on the first surface 22A of the folded exterior surface 22. On the second surface 22B of the folded exterior surface 22 opposite to the first surface 22A, the absorbent article 21 is placed in a position facing the engaging portion 23 in a state where the absorbent article 21 is stored in the packaging bag 11. A portion 24 that can be mechanically engaged with the engaging portion 23 is provided. The engaging portion 23 is, for example, a hook-and-loop fastener (for example, hook tape), and the engageable portion 24 is a non-woven fabric. Of course, you may arrange a hook-and-loop fastener in the part 24 which can be engaged. Further, if the exterior surface itself is made of non-woven fabric, the exterior surface functions as a portion 24 that can be engaged, and therefore the engageable portion 24 may not be provided separately on the exterior surface. The plurality of absorbent articles 21 are in a state in which the engaging portions 23 of the adjacent absorbent articles 21 </ b> A and 21 </ b> B can engage with each other, and are arranged in parallel to the left and right side surfaces 112. ing.

As one surface of at least the left and right side surfaces 112 of the packaging bag 11, for example, a perforation 14 is formed in which an opening for taking out an absorbent article is formed on the right side surface 112R. The perforation 14 includes intermittent cuts.
The opening made by cutting a part of the packaging bag 11 along the perforation 14 takes out the absorbent article 21 to the front side so as to peel off the engaging portion 23 and the engageable portion 24. The absorbent article 21 (21B) to be taken out next when the absorbent article 21 (21A) is taken out has a size to be retained inside the opening.

Next, a method of taking out the absorbent article 21 from the above-described absorbent article packaging structure 10 will be described with reference to FIG.
As shown in FIG. 2, when the perforation 14 is formed in a plurality of stages (two stages in the illustrated example), a part 11 </ b> A of the packaging bag is cut out along the uppermost perforation 14 to open the opening 16. make. The drawing shows a state in which a part 11A of the packaging bag is cut off partway, but the part 11A of the packaging bag is completely cut off from the packaging bag 11 along the perforation 14, and the opening 16 is formed. It is done. In addition, when the opening part 16 is made in the upper perforation 14 (14A) and all the upper absorbent articles 21 are pulled out, the packaging bag 11 along the next perforation 14 (14B). A part of is cut out to make an opening (not shown).

Next, hold the folded portion 25 side of the absorbent article 21 closest to the opening 16 and take it out from the opening 16 so that it is pulled out toward the front (for example, in the direction of the arrow). The engaging portion 23 is peeled off from the engageable portion 24 of the absorbent article 21 (21B) accommodated next, for example, in the direction of the arrow (see FIGS. 2 (2) and (3)). In this manner, the absorbent article 21 can be taken out from the packaging bag 11 through the opening 16. At this time, the absorbent article 21 (21B) accommodated next to the extracted absorbent article 21 (21A) is hung on the packaging bag 11 around the opening 16, so that it is not pulled out from the opening 16 and opened. It is retained inside the part 16. Therefore, the absorbent articles 21 can be easily taken out from the packaging bag 11 one by one.
In addition, it has the side by which the engaging part 23 of the absorbent article 21 is arranged, and peels off the engaging part 23 of the absorbent article 21A from the engageable part 24 of the absorbent article 21B accommodated next. Thus, the absorbent article 21A may be taken out from the opening 16 by pulling the absorbent article 21A forward. In this case, since the absorbent article 21 is folded, it is necessary to take out two sheets at both ends in the longitudinal direction of the absorbent article 21 at the same time.

  In the absorbent article packaging structure 10, since the perforation 14 is formed in the size as described above, when the opening 16 is formed along the perforation 14, absorption is performed from the opening 16. The property article 21 can be easily taken out to the front side so as to peel off the engaging portion 23 and the portion 24 that can be engaged. At that time, the absorbent article 21 (21B) to be taken out next is in an engaged state with another absorbent article and is caught inside the opening 16 and is retained. It becomes easy to take out one by one.

Further, when the absorbent article 21 (21A) is taken out from the opening 16 so as to be peeled to the near side, the absorbent article 21B stored next to the taken out absorbent article 21A is close to the inside of the opening. Since the left and right side surfaces 112L and 112R of the packaging bag 11 have the gusset structure, the shape of the packaging bag 11 near the opening 16 is easily maintained, and the next absorbent article 21 (21B) can be taken out. It becomes easy.
Further, the packaging bag 11 has a folded portion at the boundary between the front and rear surfaces 111 and 112 on the top and bottom of the opening 16 even if the opening 16 is made to reach the front and rear surfaces 111 from the left and right side surfaces 112. Excellent shape maintainability.
Moreover, since the said engaging part 23 is distribute | arranged to the exterior surface 22 of the absorbent article 21, when attaching this absorbent article 21 to pants etc., it has the effect | action that the engaging part 23 engages with pants etc. . Accordingly, the absorbent article 21 is less likely to be displaced with respect to the mounting position of the pants or the like.

The perforation 14 is preferably formed so that the opening 16 formed along the perforation 14 satisfies the following conditions. That is, the length in the height direction of the opening 16 is shorter than the length in the height direction of the folded absorbent article 21 housed in the packaging bag 11, and the folded absorption housed in the packaging bag 11. The opening 16 is formed so as to satisfy one or both of the fact that the length of the opening 16 in the width direction is shorter than the length of the property article 21 in the width direction.
Accordingly, when the absorbent article 21 (21A) is taken out from the opening 16 so as to be peeled away, the next stored absorbent article 21 (21B) is placed in the packaging bag 11 around the opening 16. Since it is caught and retained inside the opening 16, it becomes easy to take out the absorbent articles 21 one by one. When the entire exterior surface, or the entire exterior surface facing the engaging portion 23 in the packaging bag 11 or a predetermined wide area is constituted by a nonwoven fabric, the region 24 that can be engaged becomes wider, so that the adjacent absorption Since the property article 21 is easily caught, the effect of the configuration of the present invention is more effective.

Next, a specific embodiment of the perforation 14 made in the packaging bag 11 will be described below.
The first embodiment has the configuration shown in FIG. 1, and the perforation 14 is formed on one surface of the left and right side surfaces 112, for example, a part of the front and rear surfaces 111 from the right side surface 112R, that is, a part of the front surface 111F and a part of the rear surface 111B. To the department. Alternatively, the perforation 14 may be formed on a part of the front and rear surface 111 from the left side surface 112L.
When the perforation 14 is made up to a part of the front and rear surfaces as described above, the length from the boundary between the front and rear surfaces 111 and the left and right side surfaces 112 where the perforation 14 is made to the end of the perforation 14 is, for example, The thickness of the absorbent article 21 folded and stored is 1 to 3 times, preferably 1 to 2 times, more preferably 1 to 1.5 times.
The opening 16 formed by cutting the perforation 14 is formed in a part of the front and rear surface 111. For this reason, since a part of the folding part 25 of the absorbent article 21 is exposed from the opening 16, the folding part 25 is easily held when the absorbent article 21 is taken out, and the absorbent article 21 can be easily taken out. Become.

The second embodiment has the configuration shown in FIG. 3, and the perforation 14 is formed so as to extend from one surface of the left and right side surfaces 112, for example, the right side surface 112R, to a part of the front and rear surfaces 111, that is, a part of the front surface 111F. It has been. Or it is made to reach a part of the rear surface 111B.
In the illustrated configuration, the perforation 14 is a part of the front and rear surfaces 111, for example, the front surface 111F, on the side where the folded portion 25 side of the absorbent article 21 folded from one surface of the left and right side surfaces 112, for example, the right side surface 112R. It is made to reach. Similarly, it is made to reach a part of the front surface 111F on the side where the folded portion 25 side of the absorbent article 21 is folded from the left side surface 112L of the other side of the left and right side surfaces 112.
Although the folded portion 25 of the folded absorbent article 21 is disposed on the front surface 111F, conversely, when the folded portion 25 is disposed on the rear surface 111B, the perforation 14 is, for example, a part of the rear surface 111B from the right side surface 112R. Made to reach the department.

Further, the perforation 14 may be formed on both the left and right side surfaces 112.
Since the perforations 14 are formed on both the left and right side surfaces 112, for example, when looking toward the right side surface 112R, for example, when the folded portion 25 of the folded absorbent article 21 exists on the left side (front side 111F side), at least The perforation 14 is formed from the right side surface 112R to a part on the front surface 111F side. When the absorbent article 21 is taken out from the perforation 14, a part of the packaging bag 11 is cut from the front surface 111F along the perforation 14 to create an opening, and the folded portion 25 of the absorbent article 21 is formed from the left side. Take it out by pulling it toward you.
On the other hand, in the left side surface 112L on the opposite side, the perforation 14 is made from the left side surface 112L to a part on the front surface 111F side. When taking out the absorbent article 21 from the perforation 14, a part of the packaging bag 11 is cut out from the front surface 111F along the perforation 14 to create an opening, and the folded portion 25 of the absorbent article 21 is formed from the right side. Take it out by pulling it toward you. Therefore, an opening can be made in a direction in which a person who takes out the absorbent article 21 can easily take out. That is, the opening can be made according to the dominant hand of the person who takes out.
In the drawing, the perforations 14 are made on both sides of the left and right side surfaces 112, but the perforations 14 may be made only on one side. When the perforations 14 are formed on both the left and right side surfaces 112, the degree of freedom in taking out is increased as described above.

  Although not shown, when the folding part 25 of the absorbent article 21 is disposed on the rear surface 111B side, the perforation 14 is formed from the left and right side surfaces 112 to a part of the rear surface 111B. Also in this case, the same effect as described above can be obtained.

  Further, the third embodiment has the configuration shown in FIG. 4, and the perforation 14 is made only on the left and right side surfaces 112. In this case, even if a part of the packaging bag 11 is cut off along the perforation 14, the front and rear surfaces 111 remain without being cut off, so that the shape maintenance of the packaging bag 11 is good. Accordingly, the second and subsequent absorbent articles 21 can be easily taken out. In the drawing, the perforations 14 are made on both sides of the left and right side surfaces 112, but the perforations 14 may be made only on one side. When the perforations 14 are formed on both sides of the left and right side surfaces 112, the degree of freedom in taking out is increased.

Furthermore, a 4th embodiment is the structure of the perforation 14 shown in FIG.
As shown in FIGS. 5 (1) and 5 (2), the folding part 25 of the absorbent article 21 is disposed on one surface (for example, the front surface 111F) side of the front and rear surface 111 side. When taking out the absorbent article 21 with the folded portion 25 side, the perforation 14 is made to reach a part of the front and back surface 111 as in the first embodiment so that the takeout is easy. ing.
The absorbent article 21 stored in the packaging bag 11 may be disposed on the right side or on the left side when the folding part 25 is disposed on the right side as viewed from the take-out person. In addition, in the case of the engaging part 23 (refer said FIG. 1), it is distribute | arranged to the said folding part 25 at the left-right opposite side. For this reason, when the packaging bag 11 is manufactured, it is preferable that the left and right sides of the perforation 14 are made in advance so as to cover a part of the front and rear surface 111 so that both of them can be handled. Further, it is preferable to prepare a perforation 14B in which the opening ends only on the left and right side surfaces 112 so that one side of the opening formed by cutting the perforation 14 on the front and rear surfaces 111 does not reach. Thus, when a part of the packaging bag 11 is cut along the perforation 14 from the folding part 25 side by making the perforation 14B, the side opposite to the folding part 25 in the left and right side surfaces 112 is provided. The end of the opening can be stopped by the perforation 14B, and the opening need not be enlarged unnecessarily. In the structure of the perforation 14 (including the perforation 14B), the arrangement of the folded portion 25 of the absorbent article 21 can be arranged on the right side or the left side.

In addition, when a part of the packaging bag 11 is cut from the perforation 14 on the front and rear surface 111 side to make an opening, the shape of the perforation 14 that terminates in the left and right side surfaces 111 is not to stop the opening operation. Ingenuity is necessary.
For example, at the intersection of the perforation 14 and the perforation 14B, the perforation 14B is formed in a direction opposite to the direction of cutting along the perforation 14. The shape of the perforation 14B is preferably an arc as shown in the figure. Or as shown to FIG. 6 (1), (2), the shape of the perforation 14B between the perforations 14 may be a convex polygonal line composed of two or more connected sides. In this case, as shown in FIGS. 6 (3) and 6 (4), it is more preferable that the corner portion has an arc shape. The illustrated example is an example, and may be a convex polygonal line having another configuration.

  Further, the opening 16 (see FIG. 2) formed by cutting the perforation 14 (including the perforation 14B) is folded so that the height of the opening 16 is accommodated in the packaging bag 11. It is 40% or more and 90% or less of the length in the height direction of the absorbent article 21, and the length in the width direction of the opening 16 is in the width direction of the folded absorbent article 21 stored in the packaging bag 11. It is 80% or more and 130% or less of the length. Preferably, the height direction is 50% or more and 80% or less, the width direction is 85% or more and 115% or less, and more preferably, the height direction is 60% or more and 70% or less, and the width direction is 90%. It is 100% or less. However, the length of the opening 16 in the height direction does not become longer than the length of the folded absorbent article 21 in the height direction. In addition, the length of the opening part 16 here is a length in a developed state.

7 (1), the perforation 14 has an oval shape in a developed state. However, as shown in FIGS. 7 (2) to (4), the perforation 14 is rectangular, elongated hexagonal, elongated. It can be made into various shapes such as octagons or those whose corners are arc-shaped although not shown.
For example, when the perforation 14 is oval, the shape of the end of the opening 16 is made semicircular when the packaging bag 11 is cut along the perforation 14 to make the opening 16, so that the absorbent article Even if 21 is taken out many times, the opening 16 is not easily broken. Further, there is an advantage that the perforation 14 can be easily cut from the arc-shaped portion when the opening 16 is formed.
In addition, even when the perforation 14 is formed in a rounded, rectangular, elongated hexagonal shape, elongated octagonal shape, etc., the opening 16 is broken even if the absorbent article 21 is removed many times in the same manner as described above. It becomes difficult. Further, since the corner portion is easily torn, it is convenient to use it as an opening.

  Furthermore, when the perforation 14 is made up to at least part of the front surface 111 side, there is a gap between the absorbent article 21 on the front surface 111 side and the packaging bag 11, Since there is a gap between the folded absorbent article 21 and the packaging bag 11 on the opposite side to 25, the perforation 14 can be pushed by allowing the packaging bag 11 of the perforation 14 part to be pushed into the gap. It is easy to start cutting. Therefore, it is preferable that the perforation 14 is made so as to reach at least a part of one surface on the front and rear surface 111 side from the viewpoint of easy cutting.

  The perforation 14 is configured by a closed line, but the opening 16 formed by cutting the perforation 14 is a portion 24 where the absorbent article 21 can be engaged with the engagement portion 23 on the front side. If the absorbent article 21 to be taken out at the time of taking out the absorbent article 21 has a size to be retained inside the opening 16, Two crossing lines 141 and 142 as shown in FIG. The packaging bag 11 is cut along the two intersecting lines 141 and 142, and the cut portion of the packaging bag 11 is connected by a line connecting the adjacent ends of the intersecting lines 141 and 142 (a line indicated by a two-dot chain line in the drawing). The opening 16 is formed by folding.

In the above embodiment, the packaging structure 10 in which the absorbent article 21 is stored in two stages has been described. However, even if the absorbent article 21 is stored in one stage, the absorbent article 21 has three or more stages. Even if stored, as long as the perforation 14 corresponding to the storage position of the absorbent article 21 at each stage is formed, the above-described configurations can be employed.
When taking out the absorbent article 21 from the packaging bag 11 in which the absorbent articles 21 are stored in a plurality of stages, first, the packaging bag 11 is cut along the perforation 14 from the upper stage side to create the opening 16, and the opening 16 Then, the upper absorbent article 21 is taken out. After the removal of the absorbent article 21 on the upper stage is completed, the packaging bag 11 is cut along the perforation 14 of the next stage to create an opening 16, and the absorbent article 21 of the corresponding stage is formed from the opening 16. Take out. Therefore, the absorbent article 21 accommodated in a plurality of stages in the packaging bag 11 can be easily taken out sequentially from the upper stage side.

In addition, the packaging bag 11 is usually made of an opaque bag. In that case, in what appearance the absorbent article 21 stored in the packaging bag 11 is stored. It may be difficult to understand. Therefore, as shown in FIG. 9, the packaging bag 11 indicates that the absorbent article 21 is taken out from the folded portion 25 side on the side where the folded portion 25 of the absorbent article 21 housed therein is arranged. It is preferable to have a mark 31. The mark 31 may be the same as the mark indicating the position where the packaging bag 11 starts to be cut along the perforation 14.
Examples of the mark 31 include an arrow in the direction of the perforation 14 on the front and rear surfaces 111 (the front surface 111F in the illustrated example) on the side where the folded portion 25 of the absorbent article 21 is disposed and on the outside of the perforation 14. Draw an arrow as a landmark to face. This arrow is preferably printed simultaneously with printing on the surface of the packaging bag 11.
Since such a mark 31 is provided, the position at which the packaging bag 11 starts to be cut along the perforation 14 is clarified, and the arrangement direction of the folded portion 25 of the absorbent article 21 is also clarified, and is close to the mark 31. Since the absorbent article 21 can be peeled off from the folded portion 25 of the absorbent article 21, the absorbent article 21 can be easily peeled off.

  As a modified example of the mark 31, there is a method of using itself as the mark 31 as a form in which a part of the perforation 14 protrudes outward as shown in FIG. Further, a mark 32 having a description indicating “open mouth” may be provided in the vicinity of the mark. Further, as shown in FIG. 10 (2), there is a method of attaching an arrow balloon mark as the mark 31 indicating that the portion 14T where the perforation 14 protrudes to the outside is a peeling portion. Also in this case, the mark 31 may be marked with “open mouth”.

Next, an example of a method for making the perforation 14 in the packaging bag 11 will be described below.
As shown in FIG. 11 (1), perforation processing is performed in which a perforation 14 is put into the packaging bag 11 in a printing process before gusset processing. At this time, perforations 14 are made simultaneously with the front and back of the packaging bag 11. Therefore, as shown in FIG. 11 (2), it is suitable to make the perforation 14 symmetrically as viewed from the left and right side surfaces 112 of the packaging bag 11. Then, the gusset process which makes a gusset structure in the packaging bag 11 is performed. As a result, the perforations 14 formed on the front and rear surfaces 111 can be made shorter than the folding length of the gusset structure.

On the other hand, it is difficult to make the perforation 14 after performing gusset folding. For example, as shown in FIG. 12 (1), if the length of the perforation 14 formed on the front and rear surface 111 side is shortened in the gusset-folded packaging bag 11, the sewing machine is within the range indicated by the dotted line in the drawing. Eye 14 must be made. As a result, there is an area where the perforation 14 is not formed at the center of the left and right side surfaces 112. With this, the perforation 14 becomes discontinuous, and an opening cannot be created by cutting the packaging bag 11 along the perforation 14.
For this reason, as shown in FIG. 12 (2), when the perforation processing is performed on the gusset-folded packaging bag 11, if the perforations 14 are not formed in all the folded portions, the perforations 14 continuous to the left and right side surfaces 112 are formed. Can't make. For this reason, the length L1 of the perforation 14 formed on the front and rear surfaces 111 is longer than the length L2 of the perforation 14 formed on the gusset portions of the left and right side surfaces 112. In such a perforation 14, when the packaging bag 11 is cut along the perforation 14 to create an opening, there is a problem that the opening becomes too large. Therefore, it is preferable to make the perforation 14 before gusset processing.

  A production method for forming a left-right asymmetric perforation centering on gusset folding is possible by placing a perforation at a sheet-like stage before processing into a bag shape in a bag making process for producing a packaging film. As an example of a method for producing a packaging bag, inflation processing, printing, and bag making processing are performed in this order. Inflation processing is a step of opening for printing and processing into a film, and bag making processing is a step of processing into a bag, folding, and perforating. Normally, perforation is performed after folding, but if asymmetrical perforations are to be made, the perforation is performed in the state of the sheet before the bag forming process, and then the bag processing and folding are performed. It becomes possible by doing.

  In the absorbent article packaging structure of the present invention, the absorbent article in a stored state in which the absorbent articles are engaged with each other is taken out one by one by pulling them one by one and the remaining absorbent article is removed. The article can be kept in the package without being disturbed. In particular, when the exterior surface of the absorbent article is composed of a nonwoven fabric considering the texture, the absorbent articles are easily engaged with each other in the package, and it is difficult to take out and fluff is present on the exterior surface. Although it is likely to occur, the packaging structure of the present invention can sufficiently cope with such a problem.
