The bonding portion 3 is a portion where the packaging sheets 21 adjacent in the thickness direction are bonded together with an adhesive 3h (see FIG. 8 etc.) such as a hot-melt adhesive. is provided at the end of the

The joint portion 2 is a joint portion in which the packaging sheets 21 are crimped (for example, heat welding, ultrasonic welding, etc.) and sealed with an adhesive or the like. In FIG. 3 and the like, the joint portion 2 is indicated by cross hatching. The joint portions 2 are provided at both ends in the longitudinal direction and are substantially rectangular regions along the width direction. A plurality of rectangular welding portions m (crimping portions) are provided in the joint portion 2 of the present embodiment (see FIG. 10). In addition, the joint 2 of the present embodiment is formed by an assembly of welded portions m in which a plurality of welded portions m are arranged in an arbitrary pattern. The welded portion m of the joint portion 2 may be, for example, a plurality of circular welded portions arranged in a zigzag pattern. Also, the joint portion 2 positioned on one side in the longitudinal direction is referred to as one side joint portion 2a, and the joint portion 2 positioned on the other side in the longitudinal direction is referred to as the other side joint portion 2b. The one-side joint portion 2a and the other-side joint portion 2b of the package 1 of the present embodiment are provided in the central portion in the thickness direction, respectively, and the one-side joint portion 2a and the other-side joint portion 2b are arranged are provided at substantially the same positions.

In the package 1 of the present embodiment, the outer ends 2e of the joints 2 extend in the width direction, and the direction along the outermost outer ends of the joints 2 in the longitudinal direction extends in the width direction. The direction along the outer end of the outer end 2e of the joint 2 is orthogonal to the longitudinal direction and the thickness direction.

It should be noted that the packaging body 1 having a plurality of folded portions F does not necessarily have all of the folded portions F formed on the napkin 1 or the packaging sheet 21 as creases. For example, the crease of the first folded portion F1 formed in the first fold from the unfolded state leaves a stronger mark than the seventh folded portion F7 formed in the last fold. When the package 1 in the wrapped state is viewed along the longitudinal direction, the R of the outline is larger on the outside than on the inside, so that the trace of the folded portion F is less likely to remain. In other words, in the package 1 in a packaged state having a plurality of folding portions F, the folding portions F provided on the inner side in the thickness direction have stronger creases, and the folding portions F provided on the outer side in the thickness direction have a stronger tendency to fold. The more F, the weaker the crease is provided.

The length of the package 1 in the longitudinal direction is preferably 100-150 mm. The longitudinal length of the package 1 of this embodiment is 135 mm. By setting the length of the package 1 in the longitudinal direction within this range, the package 1 can be easily gripped with the whole fingers. For example, when gripping as shown in FIG. 9, if the length of the package 1 in the longitudinal direction is less than 100 mm, it is difficult to touch the package 1 with all five fingers, and the package 1 tends to be unstable. . On the other hand, when the length of the package 1 in the longitudinal direction exceeds 150 mm, the region where the wearer's fingers cannot touch the package 1 becomes too large, and the portion protruding from the wearer's hand becomes wide and protrudes. There is a risk that the packaging body 1 will be damaged by hitting the part against the outside.

When the napkin 1 and the packaging sheet 21 are expanded from the state shown in FIG. 7A with the third folding portion F3 as a starting point, the state shown in FIG. 7B is obtained. When the napkin 1 and the packaging sheet 21 are unfolded from the state shown in FIG. 7B with the second folding portion F2 as a starting point, the state shown in FIG. 7C is obtained. When the napkin 1 and the packaging sheet 21 are expanded from the state shown in FIG. 7C with the first folding portion F1 as a starting point, the state shown in FIG. 5 is obtained.

In addition, in the package 1 of the present embodiment, since the portions folded in the thickness direction starting from the first folding portion F1 are further folded back, the second folding portions F2a, F2b, the third folding portions F3a, F3b and fourth folding portions F4a and F4b are formed. Specifically, in the packaging body 1, the second folding part F2 is formed so that the outer surfaces of the packaging sheet 21 folded back at the first folding part F1 face each other. (See FIG. 5) has a second folding portion F2a, a third folding portion F3a, and a fourth folding portion F4a formed on one side in the vertical direction of the first folding portion F1. A second folding portion F2b, a third folding portion F3b, and a fourth folding portion F4b are also formed on the other side in the vertical direction. Since the package 1 having such a folding part F is compactly folded and the number of folds is small, when the wearer opens the package 1, the number of unfolding is reduced, and the package 1 can be easily opened. easier.

In the present embodiment, the portion folded in the thickness direction starting from the first folding portion F1 is used as the package 1 that is further folded back, but the present invention is not limited to this. For example, the folding width of the portion folded from the first folding portion F1 may be reduced, and the portion once folded may not be folded again. Moreover, the structure which does not form the folding part F may be sufficient. For example, the napkin 1 and the packaging sheet 21 may be wound in the longitudinal direction of the napkin 1 (the packaging sheet 21) to be rounded into a roll.

<<Ease of gripping package 1>>
In general, when the five fingers of the hand are bent inward and gripped, the inner annular shape formed by the fingers is not a perfect circle but a curved shape close to an ellipse. Therefore, it is easier to grip a cylindrical object with a curved cross-section that is close to an elliptical shape than a cylindrical object with a perfectly circular cross-section. If a columnar absorbent article package having a perfect circular cross section is gripped, the contact area between the fingers and the palm of the hand and the outer surface of the absorbent article package is reduced. Your body may slip out of your hand. In addition, since a columnar shape with a perfect circular cross section easily rolls on a flat surface, the absorbent article package may roll down in a toilet or the like and adhere to the ground of the toilet. There was a possibility that the package would become unsanitary.

On the other hand, as shown in FIG. 8, the package 1 has a length W in the width direction longer than the length T in the thickness direction at the center CC in the longitudinal direction of the package 1 (T<W ), half of the length W in the width direction (1/2W) is shorter than the length T in the thickness direction (1/2W<T). Further, the length in the direction along the outer end of the cross section perpendicular to the longitudinal direction at a predetermined position between the joints 2 of the package 1 is shorter than the length L2 of the outer end 2e in the direction along the outer end. The “predetermined position between the joint portions 2” refers to an arbitrary position between the one side joint portion 2a and the other side joint portion 2b in the longitudinal direction. That is, between the joint portions 2 at both ends in the longitudinal direction, there is a portion in which the length in the direction along the outer end is shorter than the length L2 of the outer end 2e. As long as it has a portion shorter than the length L2 of the outer end 2e somewhere between . In layman's terms, even a part of the package 1 in the longitudinal direction may have a portion whose length in the direction along the outer edge is shorter than the length of the outer edge 2e. As a result, the package 1 can be easily gripped, and the possibility of accidentally dropping the package 1 can be reduced to facilitate hygienic maintenance.

Specifically, in the present embodiment, the "direction along the outer edge 2e" is defined as the direction along the width direction, and the "predetermined position" is defined as the center CC in the longitudinal direction. As shown in FIGS. 3 and 8, at the center C-C in the longitudinal direction of the package 1, the length W in the width direction is longer than the length T in the thickness direction (T<W), and the length in the width direction Half of the width W (1/2W) is shorter than the length T in the thickness direction (1/2W<T), half of the length W in the width direction (1/2W) is shorter than the length T in the thickness direction By being short (1/2W<T), at the center CC in the longitudinal direction of the package 1, the length T in the thickness direction is greater than the length W in the width direction. The ring shape fits well, making it easy for the wearer to grip.

Generally, when the five fingers of the hand are bent inward and held, the inner ring shape formed by the fingers is not a perfect circle, but a curved shape close to an ellipse. FIG. 9 is a diagram illustrating a state in which the package 1 is gripped. In the cross section at the center CC in the longitudinal direction of the package 1, the length W in the width direction is longer than the length T in the thickness direction, so that when the package 1 is gripped, the package 1, The width direction part that is longer than the length in the thickness direction fits the palm, and the thickness direction part that is shorter than the length in the width direction fits the curved ring shape made by the fingers of the hand, so the cross-sectional shape Compared to gripping a cylindrical object with a perfect circle, it is easier to fit inside the ring shape with fingers and is easier to grip. In addition, when gripping the package 1, it becomes easier to increase the contact area between the fingers or the palm of the hand and the outer surface of the package 1, and it becomes easier to reduce the risk of the gripped package 1 slipping out of the hand. . Furthermore, since the cross-sectional shape at the center CC in the longitudinal direction is a perfect circle, the risk of rolling when placed on a flat surface can be reduced, so the risk of dropping on the ground such as a toilet can be reduced. , the absorbent core 11 and the napkin 10 housed inside can be easily kept sanitary.

In addition, the length L1 in the direction along the outer end of the cross section perpendicular to the longitudinal direction at the longitudinal center CC between the joints 2 of the package 1 of the package 1 is the outer edge in the direction along the outer end. By making the end 2e shorter than the length L2, for example, the risk of the package 1 falling from the wearer's hand holding the package 1 as shown in FIG. 9 can be reduced. The arch (ring) formed by the fingers of the wearer's hand holding the package 1 has a size corresponding to the length L1 in the direction along the outer edge of the cross section of the center CC in the longitudinal direction. there is Therefore, even if the package 1 is about to slip off from the gripped state, the package has a length longer than the length L1 in the direction along the outer end of the cross section of the center CC in the longitudinal direction. The outer end 2e of the body 1 is likely to be caught by an arch (ring) formed by fingers, or the package 1 is placed at a predetermined position where the length in the direction along the outer end is shorter than the outer end 2e. By making it easier for the hand holding 1 to fit in, the risk of package 1 dropping and being completely separated from the hand can be reduced.

It is preferable that the length T in the thickness direction of the package 1 is 10 to 50 mm. Academic paper "Relationship between sensory evaluation of ease of grasping a cylindrical object and palm arch" (Transactions of the Japan Society of Mechanical Engineers, Vol. 66, No. 641 (2000-1), Takao Yataka, Keijiro Yamamoto, According to Kenichi Hori), among the arches formed in the hand, the arch formed between the thumb and the forefinger was easily grasped by 20 subjects between the ages of 20 and 24. As a result of examining the contact sphere radius R, it was found that when the contact sphere radius R is 15 mm to 40 mm, it comes into proper contact with the hand and fits easily in the palm of the hand. In other words, when the length T in the thickness direction of the package 1 is shorter than 10 mm, it is likely to fall out of the palm of the hand. On the other hand, if the length of the package 1 in the thickness direction is greater than 50 mm, it will be larger than the diameter of the circle formed by the thumb and forefinger of a Japanese woman's hand, making it difficult to grip. Therefore, by setting the length of the package 1 in the thickness direction to 10 to 50 mm, it is not too small or too large for Japanese women's hands, and the risk of slipping down is reduced, and it is possible to hold it in the palm of the hand. Since it becomes easy to fit, the package 1 can be easily grasped and gripped.

The length in the thickness direction and the length in the width direction of the package 1 can be measured by a well-known method. For example, using a dial thickness gauge ID-C1012C manufactured by Mitutoyo Co., Ltd. or equivalent, the target site (each length in the center CC in the longitudinal direction) is pressurized at, for example, 3.0 gf/cm ² Let the measured values be the length in the thickness direction and the length in the width direction.

Of the angles formed by the direction along the joint 2 and the width direction, the smaller angle is preferably 45° or less. "A direction along the joint 2" is a direction along the outer edge. In this embodiment, since the direction along the outer edge is also the width direction, the smaller angle between the direction along the joint 2 and the width direction is about 0°. By setting such an angle, the outside of the joint portion 2 is larger than when the smaller of the angles formed by the direction along the joint portion 2 (the direction along the outer end) and the width direction is greater than 45°. The length of the end 2e can be easily provided long, and the longer the length of the outer end 2e of the joint 2, the wider the joint area in the joint 2, so it is easy to grip and there is a risk of falling from the gripped state. The packaging state of the packaging body 1 can be easily maintained while providing the packaging body 1 that reduces the

Also, the length W in the width direction at the center CC in the longitudinal direction of the package 1 is L1. Preferably, the package 1 has a narrow portion 1n between the longitudinal center CC and the joint 2, which is shorter than the widthwise length L1 at the longitudinal center CC. As shown in FIG. 3 and the like, the widthwise length L3 of the narrow portion 1n is shorter than the widthwise length L1 of the longitudinal center CC (L3<L1). Further, in the present embodiment, since the width direction is along the direction along the outer edge, the length L3 in the direction along the outer edge of the narrow portion 1n is along the outer edge at the center CC in the longitudinal direction. It is shorter than the length L1 in the direction (L3<L1). When the wearer grips the package 1, the wearer's fingers are easily accommodated in the narrow portion 1n. In particular, the narrow portion 1n of the package 1 is sandwiched between portions longer in the direction along the outer edge than the narrow portion 1n in the longitudinal direction. It is easy to get into a state where it fits (buried). This makes it easier for the wearer to grip the package 1, and reduces the risk of the gripped package 1 slipping off the wearer's hand.

Furthermore, as shown in FIG. 3, it is more preferable that the narrow portion 1n is positioned between the joint portion 2 and the end 11e of the absorbent core 11 in the longitudinal direction. Specifically, the package 1 of this embodiment has one end 10ea of the napkin 10 and one end of the absorbent core 11 between the longitudinal center CC and the one side joint 2a. 11ea is provided, and the other end 10eb of the napkin 10 and the other end 11eb of the absorbent core 11 are provided between the longitudinal center CC and the other joint portion 2b. On one side in the longitudinal direction, there is one side narrow portion 1n between the one side joint portion 2a and the one side end 11ea, and on the other side in the longitudinal direction, the other side joint portion 2b and the other side end 11eb, there is a narrow portion 1n on the other side. Such a narrow portion 1n located between the joint portion 2 and the end 11e of the absorbent core 11 has lower rigidity than the portion where the absorbent core 11 is provided. Therefore, the diameter of the arch (ring) formed by the fingers when grasping the part where the absorbent body 1 is provided is larger than the diameter of the arch (ring) formed by the fingers when grasping the narrow portion 1n. diameter can be reduced. As a result, it becomes easier to fit (bury) the narrow portion 1n with a finger, and at the same time, it becomes easier to grip the narrow portion 1n more strongly.

As shown in FIG. 3, in the longitudinal direction, one end 10ea of the napkin 10 and one end 11ea of the absorbent core 11 are provided between the longitudinal center CC and the one side joint portion 2a. The other end 10eb of the napkin 10 and the other end 11eb of the absorbent core 11 are provided between the longitudinal center CC and the other joint 2b. The number of wrinkles per unit area in the region from one end 11ea of the absorbent core 11 to the other end 11eb of the absorbent core 11 in the longitudinal direction indicates that the package 1 in the wrapped state has one side joint 2a and absorption in the longitudinal direction. It is preferable that the number of wrinkles per unit area between one end 11ea of the elastic core 11 is larger. Similarly, the number of wrinkles per unit area in the region from one end 11ea of the absorbent core 11 to the other end 11eb of the absorbent core 11 in the longitudinal direction of the package 1 in the wrapped state is the other joint in the longitudinal direction. It is preferable that the number of wrinkles per unit area between 2b and the other end 11eb of the absorbent core 11 is larger. The number of wrinkles in each region can be determined visually.

The portion where the absorbent core 11 is provided (the region from one end 11ea to the other end 11eb of the absorbent core 11 in the longitudinal direction) is a thick and rigid portion of the package 1. Therefore, the distance between the one side joint portion 2a and the one side end 11ea of the absorbent core 11 in the longitudinal direction and between the other side joint portion 2b and the other side end 11eb of the absorbent core 11 in the longitudinal direction The packaging sheet 21 is a portion to which strong tension is applied. Therefore, the number of wrinkles of the packaging sheet 21 in the portion where the absorbent core 11 is provided is reduced, and for the wearer, the area from one end 11ea to the other end 11eb of the absorbent core 11 in the longitudinal direction The texture of the is improved, making it easier to hold in your hand. On the other hand, a longitudinal Since there are more wrinkles than the area from one end 11ea to the other end 11eb of the absorbent core 11 in the direction, friction is more likely to occur than the part where the absorbent core 11 is provided, and the wearer can grip it. It is possible to reduce the risk of slipping the package 1 in the closed state from the palm.

The absorbent core (absorbent body) 11 of the package 1 that absorbs excrement (liquid) preferably has pulp fibers as liquid-absorbent fibers, and preferably does not have latently crimped fibers. Pulp fibers include wood pulp fibers obtained from softwood or broadleaf trees as raw materials, as well as non-wood pulp fibers made from linter, Manila hemp, kenaf, straw, bamboo, and banana as raw materials. A crimped fiber is a fiber having a crimped shape (zigzag, Ω-shaped, spiral, etc.). A latently crimped fiber is a fiber that is crimped by heating to develop a helical shape. Pulp fibers have a lower bulk recovery property than latently crimped fibers. is less likely to swell, and the package 1 can be easily maintained in a compact shape.

It is preferable that the compression recovery rate RC by the KES method in the width direction and thickness direction of the package 1 is 20% or more and 40% or less. The packaging body 1 of this embodiment is about 30%. Further, it is preferable that the linearity LC of the compression characteristic curve by the KES method in the width direction and the thickness direction of the package 1 is 0.05 or more and 0.3 or less. In this embodiment, it is about 0.15. Compression recovery rate RC in the width direction and linearity LC of the compression characteristic curve and compression recovery rate in the thickness direction and linearity LC of the compression characteristic curve are close to each other, so that the wearer can grip the package 1. Since the hardness (elasticity) in the width direction and the hardness (elasticity) in the thickness direction when folded can be made close to each other, it becomes easier for the wearer to easily grip.

Further, as shown in FIG. 10, the joint portion 2 has a plurality of welded portions (crimped portions) m, the length L2 of the outer end 2e of the joint portion 2, and the length of the center CC in the longitudinal direction. The difference (L2-L1) from the length L1 in the direction along the outer edge is preferably longer than the length Lm in the direction along the outer edge of the welded portion m (L2-L1>Lm). FIG. 10 is an enlarged view of one side in the longitudinal direction of the package 1 of FIG. 3. As shown in FIG. As described above, the plurality of welded portions m are arranged in alignment along the direction along the outer edge, along the longitudinal direction, and along the width direction. In this embodiment, the direction along the outer edge is along the width direction, so the length Lm of the welded portion m along the outer edge is also the length in the width direction. Thus, the difference (L2-L1) between the length L2 of the outer end 2e and the length L1 in the direction along the outer end at the center CC in the longitudinal direction is Since it is longer than the length Lm (L2-L1>Lm), the difference (L2-L1) between the length L2 of the outer end 2e and the length L1 in the direction along the outer end at the center CC in the longitudinal direction is 9, when the package 1 is gripped as shown in FIG. Since the outer end 2e of the joint part 2 can be easily provided longer than the arch formed by the fingers of the wearer, the risk of the package 1 slipping off the wearer's fingers and falling can be reduced, and the package 1 can be removed. Easy to keep hygienic.

Furthermore, when the package 1 is viewed inwardly from the end side in the longitudinal direction, at least one of the welded portions m is located outside the contour at a predetermined position (for example, the center CC in the longitudinal direction). is preferred. As a result, as shown in FIG. 9, even when the wearer is gripping the package 1 and the package 1 is about to slip off the wearer's hand, the welded portions m at the joints 2 prevent the packaging sheet 21 from slipping off. Since the unevenness is formed on the surface of the packaging sheet 21 while increasing the rigidity, the friction on the surface of the packaging sheet 21 is likely to increase, so that the packaging body 1 may completely slide down at the joint 2. easier to prevent.

As shown in FIG. 8, the package 1 in the packaged state includes one side packaging portion 21sa located on the most one side of the packaging sheet 21 in the thickness direction, and the other side of the one side packaging portion 21sa in the thickness direction. It has a one-side adjacent packaging portion 21ta adjacent from the side. Similarly, in the thickness direction, the packaging body 1 includes the other-side packaging portion 21sb positioned on the most other side of the packaging sheet 21 and the other-side adjacent packaging adjacent from one side of the other-side packaging portion 21sb in the thickness direction. It has a portion 21tb.

At the joints 2 at both ends of the package 1 in the wrapped state, at least a portion of the one-side packaging portion 21sa and at least a portion of the one-side adjacent packaging portion 21ta are joined. Similarly, at the joining portion 2, at least a portion of the other side packaging portion 21sb and at least a portion of the other side adjacent packaging portion 21tb are joined. In this embodiment, the one-side packaging portion 21sa, the one-side adjacent packaging portion 21ta, the other-side packaging portion 21sb, and the other-side adjacent packaging portion 21tb are stacked in the thickness direction. The side-adjacent packaging portion 21ta, the other-side packaging portion 21sb, and the other-side adjacent packaging portion 21tb are superimposed and joined by welding in the thickness direction.

In this joint portion 2, the force that separates the one-side packaging portion 21sa from the one-side adjacent packaging portion 21ta is different from the force that separates the other-side packaging portion 21sb from the other-side adjacent packaging portion 21tb. preferable. This makes it possible to adjust the magnitude of the force that separates the joint portion 2 when the package 1 is unfolded.

For example, the force that separates the one-side packaging portion 21sa and the one-side adjacent packaging portion 21ta in the joint portion 2 is made larger than the force that separates the other-side packaging portion 21sb and the other-side adjacent packaging portion 21tb. good too. The peeling of the bond between the one-side packaging portion 21sa and the one-side adjacent packaging portion 21ta is the first portion to be peeled off when unfolding the package 1, and the state shown in FIG. 6A changes to the state shown in FIG. 6B. It is something to do. The peeling of the bonding between the other side packaging portion 21sb and the other side adjacent packaging portion 21tb is the second peeling following the first bonding peeling, and the state shown in FIG. 6B is changed to the state shown in FIG. 6C. be. Therefore, by making the force for peeling off the first bond larger than the force for peeling off the second bond, the risk of unintentionally unfolding the package 1 in the wrapped state is reduced and the wrapped state is maintained. can be made easier. Once the bonding between the one-side packaging portion 21sa and the one-side adjacent packaging portion 21ta is peeled off, the subsequent peeling of the bonding between the one-side packaging portion 21sa and the one-side adjacent packaging portion 21ta is performed more quickly than the first peeling. Since it can be carried out with a small force, the unfolding of the package 1 is facilitated.

In addition, when the one-side end 21a, which is the unsealed end of the package 1, is provided on one side of the joint portion 2 in the thickness direction, the one-side packaging portion 21sa and the one-side adjacent package in the joint portion 2 The force for peeling the bond with the portion 21ta may be smaller than the force for peeling the bond between the other-side packaging portion 21sb and the other-side adjacent packaging portion 21tb. When the package 1 is unfolded, the force that separates the one-side packaging portion 21sa and the one-side adjacent packaging portion 21ta first is applied to the one-side packaging portion 21sa and the one-side adjacent packaging portion 21ta. Since the force for initial deployment can be made smaller than the force greater than the force for peeling off the bonding, the deployment of the package 1 can be easily started.

It should be noted that the "magnitude of the force that separates the bond" is both the peel strength and the bond strength. A well-known method can be used to measure the peel strength in each bonding. For example, the portion where the one-side packaging portion 21sa and the one-side adjacent packaging portion 21ta are joined (welded) in the joint portion 2 of the package 1 is cut into a predetermined size (width 5 mm), and the one-side sample piece is cut. and Similarly, the portion where the other side packaging portion 21sb and the other side adjacent packaging portion 21tb are joined (welded) in the joint portion 2 of the package 1 is cut to a predetermined size (width 5 mm), and the other side sample cut into pieces It is confirmed that the welding pattern (area of welded part per unit area) is the same between the sample piece on one side and the sample piece on the other side. Then, for each sample piece, a pair of grips is created by applying tape to the opposite ends of each wrapper. A pair of gripping parts is sandwiched between chucks of a tensile tester. Then, the load of the tensile tester is set to zero and the measurement is started. The distance between chucks is 10 mm, the tensile speed is 100 mm/min, and the maximum load is read. This measurement is performed multiple times (N=10), and the average value of the maximum load is calculated. A value obtained by converting the calculated maximum load into a load per unit width (N/25 mm) may be compared as the magnitude of peeling force (peeling strength). It should be noted that the measurement should be performed in a constant environment (for example, a temperature of 20° C. (±2° C.) and a humidity of 60% (±5%)) while the temperature of the sample piece is stable.

When the package 1 is viewed from the end side in the longitudinal direction inward, the point farthest in the thickness direction from the joint 2 in the outline of the package 1 is defined as one side vertex (vertex) Za, It is preferable to provide at least part of the one-side end 21a at a position different from the one-side vertex Za. In the thickness direction of the package 1 of this embodiment, the side where the one-side vertex Za is located with respect to the joint portion 2 is one side, which is the upper side in FIG. The side on which the other side vertex Zb is positioned with respect to the joint portion 2 is the other side, which is the lower side in FIG.

One side apex Za of the packaging sheet 21 is formed in the longitudinal direction and thickness by the joints 2 provided at both ends in the longitudinal direction and the thickness of the napkin 10 and the packaging material 20 folded multiple times. It is the part that is pulled particularly strongly in the direction. Therefore, it is a portion of the packaging sheet 21 to which a strong tension is applied.

Even if the package 1 is folded (rolled into a roll) into a compact shape, and a strong tension is applied to the position of the vertex Za on one side of the package sheet 21, the unsealed end By providing at least part of the one-side end 21a of a certain packaging sheet 21 at a position different from the one-side vertex Za, and providing it at a position where the tension is looser than the one-side vertex Za, the one-side vertex Za is provided at the position of the one-side vertex Za. The sticking of the packaging sheets 21 at the end of the packaging sheet 21 on the one side end 21a side is reduced from the part where the end 21a is provided, and the wearer includes the one side end 21a of the packaging sheet 21 Makes it easier to grab the ends. As a result, as shown in FIG. 4, it becomes easy to perform the operation of gripping the end of the packaging sheet 21, opening the gripped portion, and deploying.

In this embodiment, as shown in FIG. 8, the one-side apex Za is provided on one side of the joint portion 2 in the thickness direction, and the one-side end 21a, which is the unsealing end of the packaging sheet 21, is provided in the thickness direction. Although it is provided on one side of the joint portion 2, it is not limited to this. The one-side end 21a, which is the unsealing end of the packaging sheet 21, may be provided on the other side in the thickness direction relative to the one-side vertex Za provided on the one side in the thickness direction. end 21a may be provided at a position overlapping with the joint portion 2 in the thickness direction.

In addition, since the packaging sheet 21 of the packaging body 1 in the wrapped state is likely to be in a state where the other-side vertex Zb is also strongly tensioned, at least a part of the one-side end 21a of the packaging sheet 21 is It is preferable to have a portion provided at a position different from Zb. This makes it easier for the wearer to grasp the loose tension portion of the packaging sheet 21 rather than the overlapping portion of the one end 21a and the other vertex Zb, thereby facilitating unfolding of the package 1 in the wrapped state.

Furthermore, at least a portion of one end 21a of the packaging sheet 21 can be provided at a position different from the portion where the wing portion 10W and the wing adhesive portion 16 are arranged and the length in the direction along the outer end is increased. preferable. As a result, it becomes easier to grasp the loose tension portion of the packaging sheet 21, and the packaging body 1 can be easily unfolded.

The bonding portion 3 where the packaging sheets 21 are bonded to each other with the adhesive 3h is provided at one end 21a side of the packaging sheet 21 . The bonding portion 3 extends along one end 21a and, in this embodiment, has a rectangular shape along the longitudinal direction. By having the adhesive portion 3, it is possible to easily maintain the packaging state of the package 1 and reduce the possibility that dust or the like is mixed inside the package 1. - 特許庁

The bonded portion 3 preferably has a non-bonded portion 9 adjacent to the bonded portion 3 in a direction intersecting the direction (longitudinal direction) along one end 21a. The non-bonded portion 9 is a so-called dry edge, and is a portion where the packaging sheets 21 adjacent in the thickness direction are not bonded. In the present embodiment, the non-bonded portion 9 is a region including the one end 21a and having a predetermined width along the one end 21a. By having the non-bonded portion 9, when unfolding the package 1 in the wrapped state, it becomes easier to grasp the end including the end 21a on one side of the packaging sheet 21. As shown in FIG.

In addition, the package body 1 in a state of being wrapped by the packaging sheet 21 having the adhesive part 3 and the non-adhesive part 9 adjacent to the adhesive part 3 from one end 21a side is viewed from the end side in the longitudinal direction inward. At this time, it is more preferable that at least part of the bonding portion 3 is provided at a position different from the one-side vertex Za. Since the one-side vertex Za of the packaging sheet 21 is a portion to which strong tension is applied, excessive tension is applied to the adhesive portion 3 by providing the adhesive portion 3 at a position different from the one-side vertex Za. This reduces the risk that the packaging sheets 21 will be stuck together, making it easier to adhere the packaging sheets 21 to each other more reliably, and making it easier to maintain the packaging state of the packaging body 1.例文帳に追加

In the above-described embodiment, as shown in FIG. 3 and the like, the length L2 of the outer end of the joint 2 is longer than the length L1 of the outer end along the outer end of the center CC in the longitudinal direction of the package 1. , Regarding the length in the direction along the outer edge of the package 1, the length L2 of the outer edge at the joint portion 2 has been described as being the longest, but the present invention is not limited to this. At the center CC in the longitudinal direction, the length W in the width direction is longer than the length T in the thickness direction (T<W), and half the length W in the width direction (1/2W) is in the thickness direction Shorter than the length T (1/2 W < T), the length in the direction along the outer end of the cross section orthogonal to the longitudinal direction at a predetermined position between the joints 2 of the package 1 is the direction along the outer end It is sufficient if the package is shorter than the length L2 of the outer end 2e in .

In the packaging body 100, as in the packaging body 1 described above, the length of the outer end of the joint part 2 is along the outer edge of the cross section orthogonal to the longitudinal direction at a predetermined position between the joint parts 2 of the package body 100. Longer than direction length. Specifically, when the predetermined position is the narrow portion 1n, the length L2a of the outer end 2e of the one-side joint portion 2a is longer than the length L3 in the direction along the outer end of the narrow portion 1n. The length L2b of the outer end 2e of the other joint portion 2b is longer than the length L3 in the direction along the outer end of the narrow portion 1n.

Note that, like the joint portion 2 of the package 100, the length L2a of the outer end of the joint portion 2a on one side and the length L2b of the outer end of the joint portion 2b on the other side may be different. Specifically, as shown in FIG. 11, the outer end length L2a of the one side joint portion 2a of the package 100 is shorter than the outer end length L2b of the other side joint portion 2b.

In the package 100, the length L1 in the direction along the outer end at the center C-C in the longitudinal direction between the joints 2 is equal to the length L2 (L2a, L2b) of the outer ends at the joints 2 (2a, 2b). ) longer. Even in such a package 100, the length of the outer end 2e of the joint portion 2a on one side or the outer end 2e of the joint portion 2b on the other side is at least "predetermined positions between the joint portions 2 in the longitudinal direction". It suffices if it has a portion whose length in the direction along the outer edge is shorter than the length of the . In the package 100, at least the narrow portion 1n is at the "predetermined position", and the length L3 of the narrow portion 1n in the direction along the outer edge is longer than the lengths L2a and L2b of the outer edge 2e in the direction along the outer edge. Short (L3<L2a, L3<L2b).

Thus, in the package 100 as well, in the cross section at the center CC in the longitudinal direction, the length W in the width direction is longer than the length T in the thickness direction, so when the package 100 is gripped, Of the package 100, the widthwise portion longer than the length in the thickness direction is aligned with the palm, and the thicknesswise portion shorter than the length in the widthwise direction is aligned with the curved loop formed by fingers. Therefore, it is easier to fit inside the annular shape of the finger than when gripping a cylindrical object with a perfectly circular cross section, making it easier to grip. When the package 100 is gripped, the portion where the fingers or palm of the hand and the outer surface of the package 100 are in contact with each other is increased to reduce the risk of the gripped package 1 slipping down from the hand. Furthermore, in order to reduce the risk of rolling when placed on a flat surface compared to when the shape of the cross section at the center CC in the longitudinal direction is a perfect circle, the risk of dropping the napkin 10 on the ground such as a toilet is reduced. easy to keep hygienically.

In addition, the length L3 in the direction along the outer end of the cross section orthogonal to the longitudinal direction at the narrow portion 1n (predetermined position) between the joint portions 2 of the package 100 is Since the lengths L2a and L2b of the outer ends 2e are shorter than the lengths L2a and L2b of the outer ends 2e, even if the package 100 is about to slip off from the state in which the package 100 is gripped, the length in the direction along the outer ends of the narrow portion 1n in the longitudinal direction can be reduced. The outer end 2e of the package 100, which has a length longer than L3, is likely to get caught in the arch (ring) formed by the fingers of the hand, causing the package 1 to drop and completely separate from the hand. Helps reduce fear. In particular, the narrow portion 1n of the package 100 is sandwiched between portions longer in the direction along the outer edge than the narrow portion 1n in the longitudinal direction. It is easy to fit, and the fingers are likely to fit (buried) in the recessed portion of the narrow portion 1n, so that the wearer can easily grip the package 1 and slip the package 1 in the gripped state from the hand. It will be easier to reduce the fear of falling.

In addition, of the package 100, the portion where the wing portion 10W and the wing adhesive portion 16 are arranged, and the portion provided with the thicker absorbent core 11 are the napkin 10 and the packaging material 20 (the packaging sheet 21 and the release sheet). 22, 23) are folded over, the length in the direction along the outer edge at the position where the wing portion 10W and the wing adhesive portion 16 are arranged is the longest in the package 100 (at the center in the longitudinal direction). longer than the length L1 in the direction along the outer edge at the CC position). This is because more material overlaps the portion where the wing portion 10W and the wing adhesive portion 16 are arranged, and the thickness increases.

Although the embodiments of the present invention have been described above, the above embodiments are intended to facilitate understanding of the present invention, and are not intended to limit and interpret the present invention. Further, the present invention can be modified and improved without departing from its spirit, and it goes without saying that the present invention includes equivalents thereof.

In the above embodiment, in the thickness direction, the one-side joint portion 2a and the other-side joint portion 2b are provided in the central portion in the thickness direction, but the joint portion 2 does not necessarily have to be provided in the central portion in the thickness direction. , the joint portion 2 may be provided on one side (or the other side) of the center in the thickness direction of the package 1 . For example, when the one side joint portion 2a and the other side joint portion 2b are provided on one side of the center in the thickness direction, the other side of the packaging sheet 21 in the thickness direction is It is easy to be in a state where tension is strongly applied. Therefore, as shown in FIG. 9, when the wearer grips the package 1, the tension and elasticity of the packaging sheet 21 are different between one side and the other side in the thickness direction. It becomes easy to vary the feel of This makes it easier to grip the package 1 than in the case where one side and the other side in the thickness direction of the package 1 have the same feel when gripped and a flat feel, and the package 1 is dropped from the gripped state. It will be easier to reduce the fear of letting it happen.

In addition, in the above-described embodiment, the one-side joint portion 2a and the other-side joint portion 2b are provided at approximately the same position (central portion in the thickness direction) in the thickness direction, but the present invention is not limited to this. The one side joint portion 2a and the other side joint portion 2b may be provided at different positions in the thickness direction. For example, the one-side joint portion 2a may be provided on one side of the center in the thickness direction, and the other-side joint portion 2b may be provided on the other side of the center in the thickness direction. This makes it easier to make the tension on the packaging sheet 21 different between the one side and the other side in the longitudinal direction of the package 1 in the thickness direction. Therefore, it becomes easier to reduce the risk that both the joint of the one side joint portion 2a and the joint of the other side joint portion 2b are peeled off at the same time. is easier to keep hygienic.

Furthermore, at least one of the one side joint portion 2a and the other side joint portion 2b is provided on one side or the other side from the center in the thickness direction, and the one side joint portion 2a and the other side joint portion 2b are provided in the thickness direction. may be provided at different positions. Furthermore, the outer end 2e of the one side joint portion 2a and the outer end 2e of the other side joint portion 2b may be provided at different angles. When the outer end 2e of the one side joint portion 2a and the outer end 2e of the other side joint portion 2b are at different angles, either one of the one side joint portion 2a or the other side joint portion 2b is taken as the direction along the outer end. can be used.

The packaging bodies 1 and 100 of the above-described embodiments may be configured to include a tape member (not shown) for the wearer to grip when unsealing. For example, the packaging material 20 has a packaging sheet 21, which is a film member covering the napkin 10, and a tape member, and the packaging sheet 21 of the film member is along the longitudinal direction on the outermost surface of the package 1, 100. The tape member may be releasably adhered to an adjacent packaging sheet 21 in the thickness direction so as to straddle the edge of the outer film edge. At this time, the edge of the side of the tape member that is unfolded first is the edge of the packaging material as the unsealing edge of the packaging material 20 (corresponding to the edge 21a on one side of the package 1, 100). The tape member makes it easier for the wearer to recognize that it is the first part to be deployed when the package 1, 100 is deployed.
