=== First Embodiment ===
[1. Basic structure of tampon package 1]
FIG. 1A is a front view of a tampon packaging body 1, and FIG. 1B is a back view of the tampon packaging body 1. FIG. 2 is a view showing a state in which the bag body 10 is developed. 3A is a view of the bag body 10 as viewed from above in the longitudinal direction, and FIG. 3B is a cross-sectional view of the bag body 10 cut in the lateral direction.

  The tampon package 1 includes a bag 10 formed of a flexible sheet member 2 such as a film or a nonwoven fabric, and a tampon 20 with an applicator accommodated in the bag 10.

  As shown in FIGS. 1A and 1B, the tampon 21 includes an absorber 22 that absorbs menstrual blood and the like, and a string member 23 that extracts the absorber 22 from the body. The applicator 24 is an auxiliary tool for inserting the tampon 21 into the body, and has an outer cylinder 25 and an inner cylinder 26. The absorber 22 of the tampon 21 is accommodated at the distal end portion of the outer cylinder 25. When the inner cylinder 26 is pushed into the outer cylinder 25, the tampon 21 is pushed out from the tip of the outer cylinder 25 and inserted into the body.

  The bag body 10 has a longitudinal direction and a lateral direction orthogonal to each other, and is formed from a single sheet member 2 shown in FIG. Specifically, the sheet member 2 is formed into a cylindrical shape by overlapping the side end portions 2a and 2b of the sheet member 2 along the longitudinal direction of the bag body 10 and joining them together. In a state where the tampon 20 with an applicator is arranged inside the cylinder, the inner side surfaces of the upper end portions of the sheet member 2 are joined to form the upper joint portion 12, and the inner side surfaces of the lower end portions of the sheet member 2 are joined to each other. Thus, the lower joint portion 13 is formed. Thus, the tampon 20 with an applicator is accommodated in the bag body 10.

  Hereinafter, a portion where the sheet member 2 is overlapped is referred to as an overlapping portion 18, and a portion where the sheet member 2 is bonded is referred to as a side joint portion 11 (joint portion of the present invention). The lateral length of the side joint portion 11 is set to be equal to or shorter than the lateral length of the overlapping portion 18.

  Moreover, in the side junction part 11, as shown to FIG. 3B, the inner surface of one side edge part 2a of the sheet | seat member 2 and the outer surface of the other side edge part 2b are joined. However, the present invention is not limited thereto, and for example, the inner side surfaces of the side end portions 2a and 2b of the sheet member 2 may be joined.

  In the present embodiment, as shown in FIG. 1A, a state in which the side joint portion 11 is located at a side end portion on one side in the lateral direction of the bag body 10 is a front surface. Moreover, although the upper junction part 12 and the lower junction part 13 are formed along the horizontal direction, it is not restricted to this, The upper junction part 12 and the lower junction part 13 are along the direction orthogonal to the paper surface of FIG. 1A. It may be formed.

  Further, a cut line 30 is arranged along the outer periphery of the bag body 10. The part where the cut line 30 is arranged is weaker than the surrounding part and is easily broken. When the cut line 30 is broken, an opening is formed in the bag body 10, and the tampon 20 with an applicator can be taken out to the outside.

[2. About the cutting line 30]
4A and 4B are diagrams illustrating the lid 15 above the cut line 30. FIG. 5 and 6 are views for explaining a state after the bag body 10 is opened. FIG. 7A and FIG. 7B are diagrams for explaining a modification example of the cut line 30, and a view in a state where the bag body 10 is developed.

  Hereinafter, in the bag body 10, a portion where the tampon 20 with an applicator is arranged immediately after opening is referred to as “main body portion 14”, and a portion separated from the main body portion 14 is referred to as “lid portion 15”. Specifically, the lower portion in the longitudinal direction is the main body portion 14 and the upper portion is the lid portion 15 with respect to the cut line 30 and the virtual line La connecting both ends 30 a and 30 b of the cut line 30.

  In FIG. 4A and FIG. 4B, lines extending from both ends of the cut line 30 are illustrated as virtual lines La (second virtual lines of the present invention) that connect both ends 30 a and 30 b of the cut line 30. However, the present invention is not limited to this. For example, a line connecting both ends 30a and 30b of the cut line 30 along the horizontal direction may be set as the virtual line La.

  When the bag body 10 is viewed from above in the longitudinal direction (FIG. 3A), the cut line 30 straddles the point P <b> 1 facing the side joint portion 11 and does not straddle the side joint portion 11. Therefore, even after opening at the tear line 30, the main body portion 14 and the lid portion 15 are connected by the side joint portion 11, and the bag body 10 is not separated into two or more pieces. Therefore, the bag body 10 can be easily discarded.

  When the bag body 10 is viewed from above in the longitudinal direction (FIG. 3A), the cut line 30 is an imaginary line Lb connecting the side joint portion 11 and the point P1 facing the side joint portion 11 (present invention). 1) a portion 31 (30c to 30a) divided into two by a virtual line) and the other portion 32 (30c to 30b). As shown in FIGS. 1A and 1B, both the part 31 on one side and the part 32 on the other side of the cut line 30 are inclined downward in the longitudinal direction toward the side joint portion 11.

  Therefore, when the user picks up and down the cut line 30 and breaks the cut line 30, it extends along the extended line (virtual line La) of the cut line 30 that is inclined downward beyond the ends 30 a and 30 b of the cut line 30. Therefore, the bag body 10 is easily broken. However, the side joining portion 11 is not easily torn because the sheet member 2 is overlapped and joined in two layers. Therefore, after that, the bag body 10 is easily broken down along the both side ends 11 a and 11 b of the side joint portion 11.

  In other words, since the force that breaks the tear line 30 in the lateral direction is suppressed by the side joints 11, the bag body 10 is difficult to separate into two or more pieces, and the bag body 10 can be easily discarded.

  As a result, in a state after opening at the tear line 30 (FIG. 5), the narrow side joint portion 11 is folded in the longitudinal direction due to the weight of the lid portion 15, and the lid portion 15 hangs down from the main body portion 14. Become. Therefore, even if the user removes his / her hand from the lid portion 15, the lid portion 15 is difficult to return to the main body portion 14 side, and the opening portion 16 of the bag body 10 formed by the cut line 30 is in an open state.

  Further, when the lid portion 15 is viewed from above in the longitudinal direction (FIG. 3A), a virtual line Lc orthogonal to a virtual line Lb (the third virtual line of the present invention) that connects the side joint portion 11 and the point P1 facing it. ), The region 15A on the side joint 11 side is heavier than the region 15B on the opposite side.

  In other words, when the lid 15 is viewed from the front (FIG. 4A), the lid 11 is at the center line CL1 between the position 11c that bisects the lateral joint 11 in the lateral direction and the side end 10a of the bag body 10 that faces the lid 11. When the portion 15 is divided into two, the portion 15A on the side joint portion 11 side is heavier. This is because the area 15A of the lid portion on the side joint 11 side has a larger area and the side joint 11 exists.

  Therefore, as shown in FIG. 5 and FIG. 6, the state in which the lid portion 15 is hung from the main body portion 14 is easily maintained. Even when the bag body 10 is broken only up to the cut line 30, if the bag body 10 is tilted in the direction of the arrow shown in FIG. 4A when opened, the weight of the lid portion 15 </ b> A on the side joint portion 11 side is reduced. Therefore, it is difficult for the lid portion 15 to return to the main body portion 14 side.

  That is, in the state after opening at the cut line 30, as shown in FIG. 6, the portion 11 </ b> A of the side joint portion 11 on one side of the fold line FL of the side joint portion 11, and the other side of the fold line FL. The angle θ <b> 1 formed with the portion 11 </ b> B of the side joint portion 11 is likely to be an acute angle, and the opening 16 of the bag body 10 is in an open state.

  Since menstrual blood or the like adheres to the used applicator 24, it is generally returned to the bag body 10 and discarded. Therefore, when the opening portion 16 of the bag body 10 is in an open state, the user can return the applicator 24 to the bag body 10 without holding the lid portion 15 with a finger, and can be easily discarded. Further, since menstrual blood or the like hardly adheres to the outer surface of the bag body 10, the user's hand and the like can be prevented from becoming dirty.

  7A and 7B may be used as the cut line 30 of the modified example. Also in these cases, it is difficult for the lid portion 15 to return to the main body portion 14 side.

  Further, as shown in FIG. 1B and FIG. 2, the upper end 30 c of the tear line 30 is located above the center 10 b of the bag body 10 in the longitudinal direction of the bag body 10. That is, the cut line 30 is arranged close to one side in the longitudinal direction. The user usually breaks the tear line 30 with the side on which the tear line 30 is disposed facing upward. Therefore, even if there is no indication on the bag body 10, the bag body 10 is opened with the cut line 30 inclined downward toward the side joint portion 11.

  Examples of the cut line 30 include a structure in which a large number of holes (parts recessed in the thickness direction of the sheet member 2 or parts penetrated) are arranged at intervals. In that case, in the direction in which the cut line 30 extends, the hole is preferably made longer than the non-hole. In the opposite case, the tear line 30 is difficult to be broken, an unnecessarily strong force is applied at the time of opening, and the side joint portion 11 is easily broken. However, the length of the non-hole portion is preferably 0.1 mm or more in order to prevent unnecessary tearing of the cut line 30 during production or carrying. Moreover, the hole part (groove | channel) in which the cut line 30 continued may be sufficient.

  As the side joining part 11, what joined the sheet | seat member 2 by welding (for example, heat welding, ultrasonic welding, laser welding etc.) can be illustrated. In this case, as shown in FIG. 1A and the like, a plurality of welded portions 17 extending in the lateral direction of the bag body, that is, welded portions 17 having a predetermined length in the lateral direction, are arranged in the longitudinal direction at the side joint portion 11. Is preferably arranged.

  By doing so, as shown in FIG.5 and FIG.6, the side junction part 11 is easy to bend in a longitudinal direction along the welding part 17, and the state is easy to be maintained. Therefore, the opening 16 of the bag body 10 is in an open state, the applicator 24 can be easily returned to the bag body 10, and disposal becomes easy. However, the joining method of the side joining part 11 is not limited to welding, and may be joining with an adhesive, for example.

  In addition, as shown in FIG. 5, the side portion 31 and the other side portion 32 of the cut line 30 are inclined downward in the longitudinal direction toward the side joint portion 11, and as shown in FIG. The inner peripheral surface 10A of the bag body 10 on the side facing the portion 11 is exposed, and the opening 16 becomes wider in the longitudinal direction. Therefore, it is easy to return the applicator 24 to the bag body 10, and disposal becomes easy.

  Furthermore, the length L1 in the longitudinal direction from the upper end 30c to the lower ends 30a, 30b of the cut line 30 may be set to be equal to or larger than the maximum diameter L2 (L1 ≧ L2) of the distal end portion (outer cylinder 25) in the insertion direction of the applicator 24.

  By doing so, the inner peripheral surface 10 </ b> A of the bag body 10 is exposed wider in the longitudinal direction than the distal end portion of the applicator 24. Therefore, the applicator 24 can be returned to the bag body 10 along the inner peripheral surface 10 </ b> A of the bag body 10 by abutting the tip end portion of the applicator 24 against the exposed inner peripheral surface 10 </ b> A of the bag body 10. Therefore, disposal of the applicator 24 becomes even easier.

  Further, the cut line 30 has a symmetrical shape with respect to the center line CL2 in the lateral direction of the sheet member 2 in a state where the bag body 10 is unfolded (FIG. 2). The state in which the bag body 10 is unfolded is a state in which the joint of the side joint portion 11 is released and the bag body 10 is opened. The longitudinal direction of the sheet member 2 corresponds to the longitudinal direction of the bag body 10, and the lateral direction of the sheet member 2 (direction orthogonal to the side end portions 2 a and 2 b of the sheet member 2) corresponds to the lateral direction of the bag body 10. ing.

  The shape of the cut line 30 will be described in detail. A central portion of the cut line 30, that is, a portion (30d to 30e) straddling the point P1 that faces the side joint portion 11 when the bag body 10 is viewed from above is a longitudinal direction. It becomes the circular arc shape which becomes convex above.

  Therefore, for example, the force applied at the time of opening is smoothly switched from the lateral direction to the longitudinal direction of the bag body 10 as compared with the cut line 30 of the modified example having a trapezoidal shape illustrated in FIG. 7A. Therefore, it is possible to prevent the lateral joint 11 from being broken without suppressing the lateral force applied at the beginning of the tearing of the cut line 30, and to prevent the bag body 10 from being separated into two or more pieces.

  Moreover, it can prevent that the bag body 10 breaks by the tear line 30 before opening by not having a linear part which follows a horizontal direction like the tear line 30 of the modification of FIG. 7A. Therefore, unnecessary opening of the bag body 10 can be prevented, and the sanitary state of the tampon 20 with an applicator can be maintained.

  In a state where the bag body 2 is unfolded (FIG. 2), it is preferable that the tangent line Ld at the center 30c of the cut line 30 is along the lateral direction of the sheet member 2 (lateral direction of the bag body 10). That is, it is preferable that the center 30 c of the cut line 30 and the vicinity thereof are substantially parallel to the lateral direction of the bag body 10.

  By doing so, when the user picks and tears the top and bottom of the tear line 30, a force is easily applied to the center 30 c of the tear line 30 and its vicinity, and the user can easily start tearing the tear line 30. Therefore, it is possible to prevent an unnecessary strong force from being applied at the time of opening and tear the side joint portion 11 and to prevent the bag body 10 from being separated into two or more pieces.

  7A, the straight line portion of the cut line 30 corresponds to the tangent at the center 30c of the cut line 30. The cut line 30 of the modification of FIG. 7A can also obtain the same effect as described above.

  Further, when the center 30c of the cut line 30 and the vicinity thereof are substantially parallel to the lateral direction of the bag body 10, for example, compared to the cut line 30 of the modified example having a triangular shape shown in FIG. The width of the inner peripheral surface 10A of the facing bag body 10 can be increased (see FIG. 5). Therefore, the applicator 24 can be easily abutted against the inner peripheral surface 10 </ b> A of the bag body 10, and the applicator 24 can be easily returned to the bag body 10.

  In addition, it is preferable that the radius of curvature of the arc portion (30d to 30e) of the cut line 30 is large and the curve is gentle. By doing so, the center 30c of the cut line 30 and its vicinity become easy to follow along the horizontal direction of the bag body 10, and said effect is acquired more.

  Specifically, as shown in FIG. 2, when the lateral length L3 from the center 30c of the cut line 30 to the end 30a or 30b of the cut line 30 is 25 mm, the radius L1 of the arc portion of the cut line 30 Is preferably about 15 mm to 25 mm. If the radius L1 is smaller than 15 mm, the length of the cut line 30 in the lateral direction is shortened, and the opening 16 of the bag body 10 is narrowed. On the other hand, when the radius L1 is larger than 25 mm, the length in the longitudinal direction of the cut line 30 is shortened, and the applicator 24 is difficult to abut against the inner peripheral surface 10A of the bag body 10.

  If all the cut lines 30 have an arc shape, the bag body 10 is opened at the position of the dotted line Ld shown in FIG. 4B, and the opening 16 of the bag body 10 becomes narrow. Then, it is good to make the edge part (30d-30a and 30e-30b) of the cut line 30 into the linear shape inclined toward the downward direction of the longitudinal direction toward the side junction part 11. FIG. By doing so, the opening 16 of the bag body 10 can be widened, and the applicator 24 can be easily returned to the bag body 10.

  Moreover, as shown in FIG. 2, among the angles formed by the tangents at the ends (30d-30a and 30e-30b) of the cut line 30 and the longitudinal direction of the bag body 10, the upper angle θ2 in the longitudinal direction is It is preferably 0 ° or more and 45 ° or less. In addition, when the edge part of the cut line 30 is a linear shape like this embodiment, the straight line part shall correspond to the tangent in the edge part of the cut line 30. FIG.

  That is, the downward inclination of the end of the cut line 30 is made steep. If it does so, the area of the site | part which connects the cover part 15 and the main-body part 14 will become small, the cover part 15 will be in the state which hangs down from the main-body part 14, and the cover part 15 becomes difficult to return to the main-body-part 14 side. In addition, it is easy to ensure the length of the cut line 30 in the longitudinal direction, and the applicator 24 is easily abutted against the inner peripheral surface 10 </ b> A of the bag body 10.

  The cut line 30 may have an asymmetric shape with respect to the center line CL2 of the sheet member 2. The part 31 on the one side and the part 32 on the other side of the cut line 30 only have to be inclined downward toward the side joint portion 11, for example, the part 31 on the one side and the part on the other side of the cut line 30. 32, the length in the longitudinal direction and the length in the lateral direction are different, or the part 31 on one side of the cut line 30 has a circular arc portion as shown in FIG. 1A, whereas the part on the other side Various shapes can be implemented, for example, 32 can be configured as a straight line as shown in FIGS. 7A and 7B.

  Further, it is preferable that at least one of the ends 30 a and 30 b of the cut line 30 does not reach the side joint portion 11. In the cut line 30 of the present embodiment, both ends 30 a and 30 b do not reach the side joint portion 11.

  By doing so, the side joining part 11 is hard to tear at the time of opening, and it can prevent that the bag body 10 isolate | separates into two or more pieces. Further, unnecessary tearing of the cut line 30 can be prevented.

  On the other hand, if the cut line 30 is too far from the side joining portion 11, the opening 16 of the bag body 10 becomes narrow. Therefore, as shown in FIG. 2, in the lateral direction of the bag body 10, the length W <b> 1 from the ends 30 a and 30 b of the cut line 30 to the overlapping portion 18 of the sheet member 2 is greater than the length W <b> 2 of the overlapping portion 18. Is preferably shorter (W1 <W2).

  By doing so, the opening part 16 of the bag body 10 can be widened. Moreover, the width | variety of the site | part which connects the cover part 15 and the main-body part 14 can be made small, the cover part 15 will be in the state which hangs down from the main-body part 14, and the cover part 15 becomes difficult to return to the main-body-part 14 side. Therefore, it becomes easy to return the applicator 24 to the bag body 10. Specifically, when the length W2 of the overlapping portion 18 is 6 mm, the length W1 from the ends 30a, 30b of the cut line 30 to the overlapping portion 18 is preferably about 0.3 mm to 5 mm.

  As shown in FIG. 1B and the like, the tampon 20 with an applicator is accommodated in the bag body 10 so that the outer cylinder 25 side to be inserted into the body faces downward, and the lower ends 30 a and 30 b of the tear line 30 are the outer cylinder 25. It is preferable to be above the upper end 25a. By doing so, the outer cylinder 25 is not exposed at the time of opening, and a sanitary state is maintained. Moreover, since the used outer cylinder 25 is not exposed, it is possible to prevent the user's hand from being stained.

  Moreover, it is preferable that the upper end 24 a of the applicator 24 (inner cylinder 26) is above the upper end 30 c of the cut line 30. By doing so, it is possible to prevent the tear line 30 located at the boundary between the existing part and the non-existing part of the applicator 24 from being broken and unnecessarily broken.

  Further, the tear strength may be made different between the lateral direction and the longitudinal direction of the bag body 10 by using a sheet stretched in one direction as the sheet member 2.

  For example, when the tear strength in the lateral direction of the bag body 10 is strong, the bag body 10 is easily broken in the longitudinal direction. Therefore, the force applied at the time of opening is easily changed from the lateral direction of the bag body 10 to the longitudinal direction, and is easily broken along the cut line 30.

  Conversely, when the tear strength in the longitudinal direction of the bag body 10 is strong, the bag body 10 is easily torn in the lateral direction. Therefore, the user can easily start breaking the cut line 30.

  In addition, what is necessary is just to perform the comparison of tear strength by a well-known method, for example, can compare using a tensile tester. Briefly, in the case where the non-existing portion of the cut line 30 is obtained as a sample in the bag 10 and the tear strength in the longitudinal direction is measured, the longitudinal direction is the tensile direction, and the tear strength in the lateral direction is measured. The sample is set in a tensile tester with the transverse direction as the tensile direction. And it is good to pull a sample at a predetermined | prescribed speed | rate, obtain | require the maximum load until it reaches a fracture | rupture, and compare the value as tear strength.

=== Second Embodiment ===
FIG. 8A and FIG. 8B are views for explaining a cut line 30 of the tampon package 1 in the second embodiment. FIG. 8A is a front view of the packaging body 1 of the tampon, and FIG. 8B is a view showing a state where the bag body 10 is developed. FIG. 9 is a diagram illustrating a state after the bag body 10 is opened.

  In the cut line 30 of the second embodiment, one side portion 31 (30f to 30g) is inclined downward toward the side joint portion 11, but the other side portion 32 (30f to 30h) is lateral. Inclined upward toward the joint 11.

  In this case, as shown in FIG. 9, the lid 15 is opened so as to be twisted with respect to the main body 14. Therefore, it is difficult for the lid portion 15 to return to the main body portion 14 side, and the opening portion 16 of the bag body 10 is in an open state. Further, the inner peripheral surface 10A of the bag body 10 is exposed. Therefore, the applicator 24 can be easily returned to the bag body 10 and can be easily discarded.

  Furthermore, in the cut line 30 of 2nd Embodiment, the both ends 30g and 30h have shifted | deviated largely in the longitudinal direction. Therefore, even if the lateral force applied at the time of opening is strong and the side joining portion 11 is torn, the cut from the one end 30g and the cut from the other end 30h of the cut line 30 are difficult to continue. Therefore, it is difficult to separate the bag 10 into two or more pieces, and disposal becomes easy.

  Also in the second embodiment, as in the first embodiment, the length L1 in the longitudinal direction from the upper end 30h to the lower end 30g of the cut line 30 is equal to or greater than the maximum diameter L2 of the distal end portion of the applicator 24 (L1 ≧ L2 ) Is preferable. By doing so, the front-end | tip part of the applicator 24 can be abutted on the internal peripheral surface 10A of the bag body 10, and it becomes easy to return the applicator 24 to the bag body 10. FIG.

  Moreover, it is preferable that the ends 30g and 30h of the cut line 30 do not reach the side joining portion 11, and by doing so, unnecessary tearing of the cut line 30 can be prevented.

  Further, in the lateral direction of the bag body 10, the length W1 from the ends 30 g and 30 h of the cut line 30 to the overlapping portion 18 of the sheet member 2 is preferably shorter than the length W2 of the overlapping portion 18. By doing so, the opening part 16 of the bag body 10 can be enlarged, and the state in which the lid part 15 is twisted with respect to the main body part 14 is easily maintained.

  In addition, although not shown in figure, the site | part 32 of the other side of the cut line 30 may be straight along a horizontal direction. Also in this case, it is easy to return the applicator 24 to the bag body 10 by opening the lid portion 15 so as to be twisted with respect to the main body portion 14. However, the above can increase the length of the opening 16 of the bag body 10 in the longitudinal direction.

  As mentioned above, although embodiment of this invention was described, said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. Further, the present invention can be changed or improved without departing from the gist thereof, and needless to say, the present invention includes equivalents thereof.
