Therefore, when the opening-closing portion 120 B is peeled off up to the boundary 120 D between the opening-closing portion 120 B and the proximal portion 120 A, the user can recognize by increased reaction force applied to the user's fingers that the opening-closing portion 120 B has been peeled off up to the boundary 120 D.

Therefore, when the opening-closing portion 120 B is peeled off up to the boundary 120 D, the boundary 120 D functions as a hinge, so that the force of peeling off the opening-closing portion 120 B is absorbed as a force of rotating the opening-closing portion 120 B around the boundary 120 D.
  • the second sheet 122 has a lower flexural rigidity than the first sheet 121 . Therefore, as shown in FIG. 4 , when the opening-closing portion 120 B is peeled off up to the boundary 120 D, the opening-closing portion 120 B is held tilted toward the proximal portion 120 A under its own weight. In this state, even if the tab portion 120 C is released, the opening-closing portion 120 B is prevented from tilting toward the opening 112 . Therefore, the user can perform the opening or closing operation of the opening-closing portion 120 B and the operation of taking out the wet tissues 130 by one hand.

Therefore, when the lid 120 is formed by arranging the second sheet 122 on top of the first sheet 121 , the first sheet 121 is not present under the portion of the second sheet 122 which forms the proximal portion 120 A (see FIG. 5 ). In this case, the portion of the second sheet 122 which forms the proximal portion 120 A is acted upon by a force under its own weight. This force becomes larger away from the boundary 120 D between the opening-closing portion 120 B and the proximal portion 120 A.
  • the second sheet 122 forming the proximal portion 120 A of the lid 120 has a lower flexural rigidity than the first sheet 121 forming the opening-closing portion 120 B. Therefore, the proximal portion 120 A has a lower flexural rigidity. Particularly, a corner of the proximal portion 120 A on the side opposite to the opening-closing portion 120 B (where an edge extending from the boundary 120 D and an edge on the side opposite to the opening-closing portion 120 B meet) has a lower flexural rigidity.
  • FIG. 5 shows a lid 520 having a pointed (for example, right-angled) corner 522 a in a proximal portion 520 A on the side opposite to an opening-closing portion 520 B.
  • the opening-closing portion 520 B is formed by a laminated portion of first and second sheets 521 , 522
  • the proximal portion 520 A is formed by a portion of the second sheet 522 which protrudes from one end of the first sheet 521
  • the tab portion 520 C is formed by a portion of the second sheet 522 which protrudes from the other end of the first sheet 521 .
  • the corner 522 a Due to the pointed shape of the corner 522 a of the proximal portion 520 A on the side opposite to the opening-closing portion 520 B, the corner 522 a has a particularly lower flexural rigidity. Therefore, when the lid 520 shown in FIG. 5 is formed by arranging the second sheet 522 on top of the first sheet 521 , the corner 522 a may warp toward the first sheet 521 as shown by the hollow arrow.
  • a force F is sometimes applied to the lid 520 in a direction of the hollow arrow shown in FIG. 6 .
  • the corner 522 a of the proximal portion 520 A has a pointed shape, the force F is applied as-is to the corner 522 a .
  • the corner 522 a may bend as shown by the solid arrow in FIG. 6 .
  • the corner 522 a of the proximal portion 520 A may warp or bend. If the lid 520 having such a warp or bend is bonded to the top of the body 110 , a wrinkle will occur in the proximal portion 520 A of the lid 520 .
  • a corner of the proximal portion is provided with a greater flexural rigidity in order to prevent the occurrence of a warp or a bend so as to prevent the occurrence of a wrinkle in the proximal portion of the lid.
  • FIG. 7 shows the lid 120 of this embodiment.
  • the lid 120 of this embodiment includes the opening-closing portion 120 B formed by the laminated portion of the first and second sheets 121 , 122 , the proximal portion 120 A formed by the portion of the second sheet 122 which protrudes from one end of the first sheet 121 , and the tab portion 120 C formed by the portion of the second sheet 122 which protrudes from the other end of the first sheet 121 (which faces away from the proximal portion 120 A).
  • the corner 122 a of the proximal portion 120 A on the side opposite to the opening-closing portion 120 B is rounded. For such rounding operation, a radius of curvature of the rounded corner is set.
  • the corner 122 a of the proximal portion 120 A has a rounded shape, as shown in FIG. 7 , the force F acting upon the corner 122 a is scattered. Therefore, the rigidity of the corner 122 a becomes higher than that of a corner having a pointed shape such as a square shape. Thus, the corner 122 a can be prevented from warping or bending by the force acting upon the corner 122 a , so that the occurrence of a wrinkle in the proximal portion 120 A of the lid 120 can be prevented.
  • the radius of curvature of the corner 122 a is set to an appropriate value according to the shape (the length along the longitudinal direction of the lid 120 and the width in a direction perpendicular to the longitudinal direction of the lid 120 ) of the proximal portion 120 A, the thickness of the first sheet 121 forming the opening-closing portion 120 B, or other similar factors, such that the occurrence of a warp or a bend in the corner 122 a of the proximal portion 120 A can be prevented.
  • the shape of the corner of the proximal portion is not limited to the rounded shape.
  • a differently-shaped lid 420 is shown in FIG. 8 .
  • a corner 422 a of a proximal portion 420 A on the side opposite to an opening-closing portion 420 B is chamfered by cutting off a tip end portion of the corner 422 a .
  • a chamfering angle ⁇ and a chamfering dimension m are set.
  • the chamfering angle ⁇ represents an angle of a cutting face with respect to one of the edges which form the corner 422 a , or, for example, an angle of a cutting face with respect to an edge 422 d of the proximal portion 420 A on the side opposite to the opening-closing portion 420 B.
  • the chamfering dimension m represents a distance between a cutting point and the tip end of the corner 422 a , or, for example, a distance between a cutting point and an edge 422 c which extends from a boundary 420 D between the opening-closing portion 420 B and the proximal portion 420 A.
  • the corner 422 a of the proximal portion 420 A is chamfered, as shown in FIG. 8 , the force F acting upon the corner 422 a is scattered. Therefore, the rigidity of the corner 422 a becomes higher than that of a corner having a pointed shape such as a square shape.
  • the corner 422 a can be prevented from warping or bending by the force acting upon the corner 422 a , so that the occurrence of a wrinkle in the proximal portion 420 A of the lid 420 can be prevented.
  • the chamfering shape (chamfering angle and chamfering dimension) of the corner 422 a of the proximal portion 420 A is set according to the shape (the length and the width) of the proximal portion 420 A of the lid 420 , the thickness of the first sheet 121 forming the opening-closing portion 420 B, or other similar factors. From the above-described experimental results, it is found preferable to set the chamfering shape of the corner 422 a such that the chamfering angle is about 45 degrees and the chamfering dimension is 1.5 mm at the minimum.
  • the maximum chamfering dimension of the corner 422 a is determined according to the length of the proximal portion 420 A, a desired strength of the proximal portion 420 A or other similar factors.
  • the present invention is not limited to the construction of the above-mentioned embodiments, but rather, may be added to, changed, replaced with alternatives or otherwise modified.
  • the package of this invention is not limited to a package for storing a sheet-type article, such as wet tissues, but it can also be formed as a package for storing various other articles.
  • the opening 112 of the package 100 is described as being formed in the upper wall 110 a of the body 110 , but it is essential that at least part of the opening 112 is formed in the upper wall 110 a of the body 110 .
  • the lid 120 of the package 100 is described as being formed by the proximal portion 120 A, the opening-closing portion 120 B and the tab portion (tip) 120 C, but it may also be formed by the proximal portion 120 A and the opening-closing portion 120 B.
  • the adhesive for bonding the proximal portion 120 A of the lid 120 of the package 100 to the top of the body 110 may be an adhesive having an adhesive strength with which the proximal portion 120 A can be removably bonded to the top of the body 110 , or it may be an adhesive having a adhesive strength with which the proximal portion 120 A can be firmly (irremovably) bonded to the top of the body 110 .
  • the lid 120 of the package 100 is described as being formed by a lamination of the first and second sheets 121 , 122 , but it may be formed by a lamination of three or more sheets.
  • the opening 112 is described as being formed by forming perforations along the opening edge 112 a in the upper wall 110 a of the body 110 and peeling off the opening formation part 110 A bordered by the perforations, via the adhesive applied to the lid 120 .
  • the body 110 having the opening 112 formed in advance may also be used.
  • the first adhesive 123 is applied to an entire area of the lid 120 other than an area corresponding to the opening 112 .
  • the package 100 is not limited to the construction described in the above embodiments.
