  • a removal opening 51 of the packing bag 50 may be exposed when the sealing part 10 is peeled such that the first terminal part 10A or the vicinity thereof is held and stripped in the longitudinal direction (peeling direction), that is, stripped in the direction where the second terminal part 10B exists.
  • the form of the sealing part 10 is not limited to the form shown in the present embodiment. Taking the design and the like into consideration, the form of the part can be suitably changed such that, in a portion of the periphery thereof, sides which extend in a peeling direction thereof are made parallel to each other, or curved portions are included.
  • the second terminal part 10B of the sealing part 10 is bonded to the support part 20. Furthermore, in the vicinity of the both sides of a boundary existing between the support part 20 and the sealing part 10, a pair of slits 21 is formed, wherein the slits contact with sides of the second terminal part 10B, which extends in the cross-direction, and extend further from the contact portions. Due to the pair of slits 21, when the sealing part 10 is peeled, the peeling strength is not liable to act on the support part 20. In the position where the slits contact the second terminal part 10B, the distance between the slits 21 increases as the slit approaches the first terminal part 10A.
  • the ends of the slits 21 form a "U" like shape.
  • the slits 21 are not essential parts.
  • the label does not include slits 21, and only includes a cut line 22 (laminate cut line) and a peeling layer 23.
  • a cut line 22 which merely cuts the adhesive layer 3A and the second base material 3 is formed.
  • the first base material 2 is not cut by the cut line 22.
  • the cut line 22 exists between the pair of slits 21, and extends so that it is orthogonal (or approximately orthogonal) to the peeling direction, and the line separates the second base material 3 into a proximal area 3a, which is on the proximal side in the peeling direction, and a distal area 3b, which is on the distal side in the peeling direction.
  • a peeling layer 23 which has predetermined width and length is provided between the first base material 2 and the second base material 3. Accordingly, it is structured such that the first base material 2 and the second base material 3 are easily separated from each other. That is, at the boundary portion of the support part 20 and the sealing part 10, there is a part where the adhesive layer 2A and the second base material 3 are bonded and a part where the adhesive layer 2A and the second base material 3 are easily separated by the effect of the peeling layer 23. It is preferable that the peeling layer 23 and the cut line 22 are connected to each other, and they separate the sealing label 31 to the sealing part 10 and the support part 20 along with the slits 21.
  • the peeling layer 23 can be formed by the optionally selected method in so far as a peeling area can be formed.
  • the peeling layer 23 may be formed by coating a conventionally known peeling varnish on a predetermined part of the second base material 3, or performing conventionally known detackifying treatment to the adhesive layer 2A.
  • the laminate has a structure wherein an upper portion, which is over the peeling layer 23 (at the side where the reinforcing base material 4 exists) is peeled, and a lower portion, which is at the peeling layer 23 or below is not peeled.
  • a terminal end line (side) of the peeling layer 23 which is at the support part side and extends in the width direction thereof may be considered as a boundary of the sealing part 10 and the support part 20 for convenience sake.
  • the position and the size of the cut line 22 and the slits 21 may be optionally selected. However, it is preferable that the cut line 22 is formed along the entire width of a peeling portion of the support part 20 which reaches the slits 21. It is also preferable that the peeling layer 23 is provided along the entire length of the cut line 22. It is also preferable that the length of the peeling layer 23 and the length of the cut line 22 are the same.
  • the peeling layer 23 is shown as a structure wherein the layer is embedded in the second base material 3, the present invention is not limited thereto.
  • a structure in which the peeling layer 23 is arranged on the flat surface on the second base material is also included in the present invention.
  • a sealing label 1 is positioned and adhered to a laminate film F which is prepared in advance. Then, as shown in Fig. 2 , a cut C having a form of a removal opening 51 is formed from the lower side of the laminate film F, where the sealing label 1 is not adhered, to form the removal opening 51.
  • the depth of the cut C is preferably a depth by which the laminate film F can be certainly cut, but the second base material 3 is not cut.
  • the laminate film F and another laminate film F, which does not have an opening and does not have a sealing label 1 adhered thereto, are joined to each other, a substance is stored therein, and sealing is performed to complete the packing bag 50.
  • a distal area 3b, which is on the distal side in the peeling direction, of the second base material 3 does not follow the sealing part 10, and maintains the state adhering to the packing bag 50. That is, the distal area 3b, which is on at the distal side in the peeling direction, is not separated from the film of the packing bag 50.
  • a position where the sealing part 10 and the support part 20 are bonded has low rigidity since the position is merely formed by the first base material 2 which includes adhesive layer 2A. Accordingly, if a user releases the hand from the sealing part 10, the exposed state of the removal opening 51 can be maintained.
  • the user can remove a wet tissue 60 from the removal opening 51 and perform desired work while the packing bag 50 of the present invention is kept at hand. Even when the second and third wet tissues are taken out in succession, operation can be smoothly performed, since it is not necessary to peel the sealing part again as the exposed state of the removal opening 51 is maintained.
  • the sealing part 10 is adhered again to the packing bag 50 to seal the removal opening 51, and therefore, drying of wet tissue 60 stored in the packing bag 50 is sufficiently prevented, and the entry of foreign matter into the packing bag 50 is also prevented.
  • a cut line 22 which cuts and divides the second base material 3 is provided at the boundary between the sealing part 10 and the support part 20, and the peeling layer 23 is formed at the distal area 3b, which is on the distal side in the peeling direction. Accordingly, when the sealing part 10 is peeled, the connecting part of the sealing part 10 and the support part 20 becomes thin, and the rigidity of the part becomes lower than that of the sealing label 1 itself.
  • the state where the removal opening 51 is exposed is preferably maintained without the sealing part being returned to the former state before peeling.
  • the packing bag 50 so that the removal opening 51 is sealed openably and closably, it is possible to use the bag such that a substance is easily removed since the exposed state of the removal opening 51 is preferably maintained.
  • the strength which pulls the sealing part 10 does not act such that the support part 20 is peeled off from the packing bag 50.
  • the adhesive strength of the adhesive layer 2A is larger than the adhesive strength of the adhesive layer 3A, a situation is unlikely to occur in which the first base material 2 is peeled from the second base material in the area where the peeling layer 23 does not exist in the distal area 3b which is on the distal side in the peeling direction. Accordingly, when the packing bag is usually used, a situation can be prevented wherein the sealing label 1 is entirely peeled off from the packing bag 50 when the sealing part 10 is peeled off.
  • an area F1 where an opening is formed is a part of the laminate film F and is adhered to the sealing part 10 so that a removal opening 51 is exposed.
  • the area F1 where an opening is formed is removed from the film in advance, and the exposed surface of the adhesive layer 3A or 4A of the sealing part which covers the removal opening may be treated by the conventionally known detackifying treatment.
  • the sealing label 31 of the present embodiment is different from the sealing label 1 described above due to a third base material which is equipped to reinforce a removal opening.
  • the same reference symbols are used for constituents which are identical to those explained above, and the overlapped explanations thereof are omitted here.
  • Fig. 5 is a perspective view which shows a packaging back 50 to which a sealing label 31 is attached.
  • Fig. 6 shows a cross sectional view taken along line B-B of Fig. 5 .
  • a sheet-like or film-like third base material 4 having a form which can completely cover a removal opening 51 is attached to the sealing part 10.
  • the third base material 4 is formed to have an elliptical form which has a larger outside periphery than the removal opening 51 of the packing bag 50, and the area thereof is smaller than the area of the sealing part 10 so that the base material does not protrude to the outside of the sealing part 10.
  • the form of the reinforce base material 4 can be selected optionally and may be an ellipse, a circle, a square or the like. It is preferable that the form thereof is larger than that of the removal opening and has an identical or similar form of the opening.
  • the third base material 4 has an adhesive layer 4A (third adhesive layer) on one surface thereof which faces the side where the packing bag 50 exists.
  • the third base material 4 on another surface thereof to which the adhesive layer 4A is not provided, easy-peeling treatment is performed with a peeling varnish or the like.
  • the reinforced base material 4 is adhered to the adhesive layer 3A of the second base material 3.
  • materials of the third base material 4 those which can be used for the first base material 2 and the second base material 3 can be used.
  • the adhesive layer 4A has the adhesive strength which is similar to that of the adhesive layer 3A, and can be adhered to and peeled from the packing bag 50 repeatedly.
  • the sealing label 31 has a second cut line 32 (the third base material cut line) which has a larger outside periphery than the removal opening 51, and merely cuts the third base material 4 and the adhesive layer 4.
  • the area F1 where an opening is formed of the laminate film F is located on the inside of the second cut line 32.
  • detackifying treatment is performed on the adhesive layer 4A by printing a dot or mesh-shaped pattern, which is not shown, with a detackifying agent, such that the treatment is performed at the periphery of an area surrounded by the second cut line 32 and existing on the surface of the adhesive layer 4A which is adhered to the packing bag 50.
  • the kind of the detackifying agent and the density of the dot or mesh-shaped patterns are determined by the peeling strength which is set in advance, and for example, the density may be 30 to 50%.
  • the area where the detackifying treatment is performed can be optionally selected.
  • the treatment may be performed for an oval shape having a line width D1 shown in Fig.
  • the line width D1 is set to at least include an area existing between the second cut line 32 and the cut C, when the packing bag 50 which has the sealing label 31 is observed in planar view.
  • the line width D1 is selected so that the ring-like area 4a of the reinforcing base material, which is left on the laminate film F, can maintain the adhesion to the laminate film F, and that the area F1 where an opening is formed can maintain the adhesion to the adhesion layer 4A. That is, when the cross section thereof is observed, it is preferable that the line width D1 includes the cut line C and the second cut line 32, and the outmost part of the line width D1 does not exceed the outer peripheral end of the reinforcing base material 4a, and it is still more preferable that the outmost part of the line width D1 does not exceed the center of the width of the reinforcing base material 4a.
  • the sealing part 10 when the sealing part 10 is first peeled, as shown in Figs. 7 and 8 , the inside area surrounded by the second cut line 32 of the third base material 4 is peeled off from the packing bag 50.
  • the removal opening 51 is exposed, since the area F1, which exists as the inside area of the cut line C formed on the film F and is provided as an area where an opening is formed, moves together with the sealing part 10, while the area is adhered to the third base material 4 (the inner side of the third base material).
  • the area which exists at the outside of the second cut line 32 (hereinafter, referred to "reinforcing area 4a") has an approximately doughnut shape, and adheres to the packing bag 50 more strongly than the second base material 3, due to easy- peeling treatment which is performed on one surface thereof and the adhesive layer 4A existing on the other surface thereof. Accordingly, the area remains at the periphery of the removal opening 51, without following the movement of the sealing part 10 accompanied by peeling.
  • the reinforcing area 4a (outer part of the third base material) functions as a reinforcing layer which reinforces the periphery of the removal opening 51, and it preferably prevents occurrences of creases or slits in the periphery of the removal opening 51.
  • the reinforcing area which is a part of the third base material 4
  • the reinforcing area remains at the periphery of the removal opening 51 due to the provided third base material 4. Accordingly, in addition to the effects which are similar to that of the sealing label of the first embodiment, it is possible to prevent breakage and the like around the removal opening 51, and maintain a beautiful appearance thereof.
  • a dot-like detackifying treatment is performed at the predetermined area of the adhesive layer 4A. Accordingly, in the area, a portion where adhesive strength is relatively high and a portion where adhesive strength is relatively low are distributed at dot or mesh-shaped patterns. Accordingly, as compared with the case wherein a detackifying treatment is performed all over the area, liquid medicine and the like which are impregnated in a wet tissue 60 hardly spread on to the area. As a result, it is possible to preferably prevent failures wherein the area F1 which is used to from the opening is peeled from the third base material 4, the reinforcing area is peeled from the packing bag 50 or the like.
  • detackifying treatment may be performed for the adhesive layer at the vicinity of the first terminal part, so that a user can easily pick up the part when peeling is performed.
  • a substance which is stored in the packing bag is not limited in particular.
  • the sanitary material such as a wet tissue described above, another material such as food, conventional goods or the like may be contained.
  • the sealing label of the present invention may be applied to a packing container other than the packing bag.
  • the label may be used so that it is adhered to a container or the like made of metal or resin, which has a rigidity larger than that of the packing bag.
  • the present invention provides a sealing label wherein, when the label is peeled from a packing container, the label hardly returns to a state wherein an opening of the packing container is covered by the label.
