Description

The present invention relates to packages and containers.

2. Description of the Related Art Conventionally, packaging bodies for accommodating sheet bodies such as wet wipes, wet sheets, and dry sheets are known. One surface of the packaging body is formed with a rim portion along the outer edge of the outlet of the sheet body and a cut-off portion along the rim portion. A half-cut cut is formed along the outer shape of the cut-off portion in the lip portion. The cut is formed with a uniform depth along the contour of the detachment. A seal covering the cut-off portion is attached to one surface of the package. When the seal is peeled off, the cut-off portion is cut off along the cut to open the outlet.
For example, Patent Literature 1 discloses a wet tissue package. The outlet for wet wipes has an oval shape.

For example, when the pair of transport rolls 51 and 52 are rotated, the base material 40 is transported in one direction (moves in the transport direction DT). During the process of conveying the base material 40, the blade 56 of the die 55 bites into the extraction surface main body forming portion 41, and the lip portion 13 is formed. In the illustrated example, the long axis direction DL of the rim portion 13 is parallel to the conveying direction DT of the base material 40 .

<Effect>
As described above, the package 1 according to the above-described embodiment is a package 1 that can accommodate the wet wipes 2, and the outer edge of the outlet 12 from which the wet wipes 2 accommodated in the package 1 can be taken out. a film-like take-out surface body 11 having a rim 13 along the rim and a cut-off portion 14 having an outer shape along the rim 13; The lip portion 13 is continuous with both ends of the curve convex on the side opposite to the peeling direction DP, extends along the peeling direction DP, and includes a pair of extending portions 31 having a cut 15 and a middle portion of the extending portion 31. and a stopping portion 32 provided at and thicker than the thickness of the extension portion 31 .

According to this configuration, since a portion of the extension portion 31 is reinforced by the stop portion 32, the cut 15 of the rim portion 13 can be easily deepened. Therefore, it becomes easy to cut off the rim portion 13 . That is, it is possible to prevent the outlet 12 from not being formed when the seal 20 is peeled off, or from not being formed in the intended shape. In addition, even if the cut 15 of the lip 13 is deepened, it is possible to prevent the cut-off portion 14 from slipping or coming off during manufacturing (before the seal 20 is attached to the extraction surface main body 11). Therefore, the outlet 12 can be stably formed in the intended shape.
In addition, the airtightness of the package 1 can be maintained. Therefore, intrusion of foreign matter can be suppressed, and dryness of the wet tissue 2 can be suppressed.
In addition, since the cut-off portion 14 is cut off along the pair of extending portions 31 starting from the curved line of the rim portion 13, the cut-off portion 14 can be easily cut off smoothly. Here, if the stopper portion 32 is provided in a portion of the mouth edge portion 13 that obliquely intersects the peeling direction DP, the force when peeling off the seal 20 is dispersed by the stopper portion 32 in a direction different from the peeling direction DP. By doing so, the extraction surface main body 11 may be torn. On the other hand, according to this configuration, since the stopping portion 32 is located in the middle of the extending portion 31 extending along the peeling direction DP in the rim portion 13, the force when peeling off the seal 20 is applied to the downstream side of the stopping portion 32. can escape to the extending portion 31 (cut 15).

Since the separating portion 14 is separated along the pair of extending portions 31 and the pair of second curved portions 33 starting from the first curved portion 30 of the rim portion 13, the separating portion 14 can be smoothly separated.
In addition, since the first curved portion 30 has a smaller radius of curvature than the pair of second curved portions 33 (because the upstream end of the outlet 12 in the peeling direction DP becomes a narrow portion), the peeling of the outlet 12 Passage resistance of the wet tissue 2 at the end on the upstream side in the direction DP can be increased. For example, when the wet tissues 2 are taken out one by one from the outlet 12, it is easy to separate the wet tissues 2 on the leading side and the trailing side.

According to the above embodiment, the rim portion 13 has an arcuate shape that is convex inward in the minor axis direction DS, and the ends of the pair of extension portions 31 on the downstream side in the peeling direction DP and the pair of second curved portions 33 By further providing a pair of continuous portions 34 that continue the ends on the upstream side in the peeling direction DP, the following effects can be obtained.
Since the cut-off portion 14 is cut off along the pair of extending portions 31, the pair of continuous portions 34, and the pair of second curved portions 33 starting from the first curved portion 30 of the rim portion 13, the cut-off portion 14 can be smoothly moved. Easy to separate.

According to the above-described embodiment, since the stop portion 32 does not have the cut 15, the following effects can be obtained.
Compared to the case where the stop portion 32 has the cut 15 , it is easier to reinforce part of the extension portion 31 with the stop portion 32 , so the cut 15 of the mouth edge portion 13 can be made deeper. In addition, since it is not necessary to cut the stop portion 32 during manufacturing, productivity is excellent.

According to the above-described embodiment, the rim portion 13 has a point-symmetrical shape with the center C in the peeling direction DP as the center of rotation, thereby providing the following effects.
The separation portion 14 can be easily separated regardless of whether the separation direction DP is from one side of the separation direction DP to the other side or the opposite direction.
In addition, when the peeling direction DP and the transport direction DT during manufacturing are opposite to each other, the separating portion 14 is easily separated from the product, but the separating portion 14 shifts or comes off due to external factors such as wind during manufacturing. can be suppressed.

According to the above-described embodiment, the slit 15 is formed on the seal 20 side of the extraction surface main body 11 and is not formed on the opposite side of the extraction surface main body 11 from the seal 20, so that the following effects are obtained.
Compared to the case where the slit 15 is formed on the side of the take-out surface main body 11 opposite to the seal 20, the sealability of the package 1 can be maintained more effectively.

According to the above-described embodiment, the extraction surface main body 11 is a laminate of multiple layers 11a and 11b, which provides the following effects.
A plurality of functions can be imparted to the extraction surface main body 11, such as by stacking a layer that does not allow moisture to pass through and a layer that exhibits good printing color.

According to the above-described embodiment, the gap 15 is formed in the layer 11a except for the last layer 11b among the multiple layers 11a and 11b, thereby providing the following effects.

For example, the first curved portion 30 may be provided only on one side of the rim portion 13 in the longitudinal direction DL. For example, as shown in FIG. 7, the first curved portion 30 may be provided only on the upstream side in the peeling direction DP. For example, the rim portion 213 includes a first curved portion 30, a pair of first extension portions 31, a pair of second curved portions 233, a pair of continuous portions 34, a pair of second extension portions 235, and a third extension. A portion 236 and a stop 32 may be provided. The first extension portion 31 corresponds to the extension portion 31 of the above embodiment. The second curved portion 233 has approximately half the length of the second curved portion 33 of the above embodiment. The second extending portion 235 is continuous with the end of the second curved portion 233 opposite to the first curved portion 30 and extends in the longitudinal direction DL. The third extension portion 236 is continuous with the end of the second extension portion 235 opposite to the second curved portion 233 and extends in the minor axis direction DS. The stopping portion 32 may be provided in the middle of the pair of first extension portions 31 and the pair of second extension portions 235 respectively.

In the above embodiment, an example in which the slit 15 is formed on the seal 20 side of the extraction surface main body 11 and is not formed on the side opposite to the seal 20 of the extraction surface main body 11 has been described, but the present invention is not limited to this. For example, as shown in FIG. 8, the cut 15 may be formed on the side of the extraction surface main body 11 opposite to the seal 20 and may not be formed on the side of the extraction surface main body 11 facing the seal 20 . According to this configuration, compared to the case where the slit 15 is formed on the seal 20 side of the extraction surface main body 11 (see FIG. 4), the separation portion 14 is separated from the extraction surface main body 11 when the seal 20 is peeled off. easy.

In the above embodiment, an example in which the extraction surface main body 11 is a laminate of two layers 11a and 11b has been described, but the present invention is not limited to this. For example, the extraction surface main body 11 may be a single layer or a laminate of three or more layers.

In the above embodiment, an example in which the gap 15 is formed in the layer 11a excluding the last layer 11b among the multiple layers 11a and 11b has been described, but the present invention is not limited to this. For example, as shown in FIG. 9, the cut 15 may be formed up to the last layer 11b of the multiple layers 11a and 11b. According to this configuration, since the cuts 15 are formed in all of the multiple layers 11a and 11b, it is possible to easily cut the separation portion 14 from the extraction surface main body 11 while suppressing delamination.

In the above-described embodiment, an example in which one stop portion 32 is provided for each extension portion 31 has been described, but the present invention is not limited to this. For example, a plurality of stop portions 32 may be provided on each extension portion 31 . The number of stop portions 32 to be installed can be changed to any number according to the required specifications.

In the above embodiment, an example in which the rim portion 13 includes the first curved portion 30, the pair of extension portions 31, the pair of second curved portions 33, and the pair of continuous portions 34 has been described, but the present invention is not limited to this. . For example, the rim portion 13 may not have the pair of second curved portions 33 and the pair of continuous portions 34 . That is, the lip 13 may have a simple oval shape (elliptical shape).

In the above-described embodiment, an example in which the outlet 12 has a shape extending in the long axis direction DL along the peeling direction of the seal 20 has been described, but the present invention is not limited to this. For example, the outlet 12 may have a shape extending in a direction intersecting the peeling direction of the seal 20 . In a plan view, the outlet 12 may have an oval shape with a minor axis along the peeling direction DP. Alternatively, the outlet 12 may have a perfect circular shape in plan view. That is, the rim 13 may include a pair of extensions extending along the peeling direction of the seal 20 and having the cut 15 . That is, the extending portion is not limited to extending linearly, and may extend in a curved line.
