Description

  The present invention relates to a packaging bag for a wet sheet or the like in which the outer peripheral side of a take-out port of a bag body is reinforced by a reinforcing sheet.

  A wet bag, for example, a wet bag for wrapping a wet sheet such as a wet tissue so that the wet sheet can be taken out, a seal that seals the take-out port on the take-out side of the bag body that wraps the wet sheet The label is attached in a peelable manner via a pressure-sensitive adhesive, and when using a wet sheet, the sealing label is peeled off, the wet sheet is taken out from the outlet, and the sealing label is attached after removal. There is something which made the extraction mouth sealed.

  Since this type of packaging bag requires gas barrier properties, it is necessary to securely seal the sealing label to the bag body all around the take-out port via a pressure-sensitive adhesive after taking out the wet sheet. . However, since the bag body is made by making a single film or composite film of a thin plastic film with gas barrier properties, if the remaining amount of the wet sheet in the bag body decreases, a sealing label is attached. When this occurs, wrinkles and the like are likely to occur on the bag outlet side of the bag body. For this reason, when sticking the sealing label, it is necessary to stick it while stretching the bag around the outlet of the bag body so as not to stick the sealing label from the upper side of the bag around the outlet. is there.

  Therefore, a conventional packaging bag is provided with a shape retaining frame or a reinforcing frame on the outer peripheral portion on the upper surface side where the bag main body outlet is formed, and the peripheral portion of the outlet is provided with the shape retaining frame or the reinforcing frame. (Patent Documents 1 and 2), and further, a reinforcing sheet is attached to the periphery of the take-out port on the upper surface side of the bag body, and a sealing label is attached to the reinforcing sheet via a pressure sensitive adhesive. A worn one (Patent Document 3) has been proposed.

  In the packaging bag of Patent Document 1, a rectangular shape retaining frame is fixed to the outer periphery on the upper surface side of the bag body, and a sealing label is detachably attached to the inner periphery side of the shape retaining frame. Moreover, the packaging bag of patent document 2 uses the cover label in which the outer periphery reinforcement frame and the sealing label were integrally formed through the notch | incision, and this cover label is attached to the upper surface side of a bag main body via a pressure sensitive adhesive. The upper surface of the bag body is reinforced from the outer peripheral side with a reinforcing frame, and the sealing label is detachably attached to the upper surface of the bag body at the inner periphery of the reinforcing frame.

  The packaging bag of patent document 3 sticks a reinforcement sheet on the upper surface of the bag body, reinforces the outer peripheral part of the take-out port of the bag body with this reinforcement sheet, and attaches a pressure-sensitive adhesive to the sealing label on the reinforcement sheet. It sticks so that peeling is possible.

  However, in the case of a packaging bag that uses a conventional shape retaining frame or reinforcing frame, the shape of the shape retaining frame or reinforcement on the outer peripheral side of the sealing label is not directly retained, but the location where the sealing label is attached to the bag body is not directly retained. Since the upper surface side of the bag body is shaped by the frame and the sealing label is adhered to the inside thereof, wrinkles or the like may occur at the location where the sealing label is adhered. In addition, in order to ensure sufficient shape retention, it is necessary to use a material with good shape retention, such as a thick shape retention frame or reinforcement frame, which increases the manufacturing cost and weight. New problems such as an increase in In addition, when the reinforcing frame and the sealing label of Patent Document 2 are configured integrally, there is a problem that opening and closing operations on the sealing label side are difficult if the rigidity of the reinforcing frame is sufficiently secured.

  In the case of a packaging bag using a reinforcing sheet, the sticking location of the sealing label is directly reinforced, so that the occurrence of wrinkles at the sticking location can be temporarily eliminated. However, since only one reinforcing sheet is fixed to the peripheral portion of the bag body outlet, even when the remaining amount of the wet sheet decreases, the sealing label can be easily attached with a relatively simple operation. In order to be able to stick, it is necessary to secure a sufficient reinforcing effect by using a thick reinforcing sheet, and there are problems such as an increase in manufacturing cost and an increase in weight as in the former case.

  In view of such conventional problems, the present invention can sufficiently reinforce the peripheral portion of the bag body outlet with a reinforcing sheet without using a thick material, suppressing an increase in manufacturing cost, an increase in weight, and the like. An object of the present invention is to provide a packaging bag for a wet sheet that can be easily and reliably sealed.

  The present invention attaches a reinforcing sheet having an opening corresponding to the take-out port to the outer peripheral side of the take-out port of a bag body for packaging contents such as a wet sheet, and pressure-sensitive a sealing label that seals the take-out port In a packaging bag for a wet sheet or the like that is detachably attached to the reinforcing sheet via an adhesive, a reinforcing embossed portion is provided on the reinforcing sheet.

  In the reinforcing sheet, both sides in a direction substantially orthogonal to the sticking / peeling direction of the sealing label protrude outward from the sealing label, and the embossed portions are provided on both sides in the direction substantially orthogonal to the opening. But you can. Moreover, the said reinforcement sheet may have the said embossing part in the sticking area | region of the said sealing label at least. Further, the reinforcing sheet may have the embossed part outside at least the sticking area of the sealing label.

  The embossed portion is preferably provided in a range excluding the non-peeling portion on the side opposite to the knob portion of the sealing label, and the reinforcing sheet of the non-peeling portion is preferably configured to be flat. The sticking part where the reinforcing sheet is stuck to the bag body is continuous in the circumferential direction on the outer periphery of the take-out port, and the sticking part where the sealing label is stuck on the reinforcing sheet is continuous in the circumferential direction. It is desirable to provide in.

  The embossed portion may be continuous in the circumferential direction surrounding the opening or may be independent in the circumferential direction surrounding the opening. It is desirable that the reinforcing sheet having the embossed portion is attached to the bag body.

  The reinforcing sheet with the sealing label attached thereto may be attached to the bag body. Moreover, the said reinforcement sheet may be affixed on the film which comprises the said bag main body, and the said embossing part may be formed by embossing this reinforcement sheet and the said film. The sealing label may have an embossing portion for reinforcement in a region excluding the non-peeling portion.

  According to the present invention, the peripheral portion of the bag body outlet can be sufficiently reinforced with the reinforcing sheet without using a thick material, and an advantage that the manufacturing cost can be easily and reliably sealed while suppressing an increase in weight, etc. There is.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 to 5 illustrate a first embodiment of a packaging bag for wet sheets and the like according to the present invention. As shown in FIGS. 1 to 5, the packaging bag 1 is attached to a bag-like bag body 3 having a take-out port 2 formed on the upper surface and a pressure-sensitive adhesive 4 on the upper surface side of the bag body 3. A reinforcing sheet 5 that is attached and reinforces the outer peripheral side of the take-out port 2, and a sealing label 7 that is detachably attached to the reinforcing sheet 5 via a pressure-sensitive adhesive 6 and that seals the take-out port 2 so that it can be opened and closed. And have.

  The bag body 3 is formed by, for example, packaging a laminate 9 of a wet sheet 8 such as a wet tissue and pillow-wrapping it with a packaging film such as a plastic single film or a composite film having gas barrier properties and flexibility. In the state where the laminate 9 of the wet sheet 8 is wrapped, the opposite side to the take-out port 2 is thermally fused in the vertical direction to form a cylinder, and then thermally fused in the lateral direction on both sides of the laminate 9 and cut. After that, the cut end portion is folded and bonded to the side surface to form a rectangular parallelepiped shape in accordance with the shape of the laminate 9.

  The bag body 3 may be finished in an arbitrary shape according to the number of wet sheets 8 and the amount of packaging. The bag body 3 may be in a packaging form other than pillow packaging. Further, the contents in the bag body 3 may be other than the wet sheet 8. For example, it may be a wet food, a dry food, an aromatic fragrance, or the like.

  A cut line 10 such as a half cut and a perforation is formed along the shape of the takeout opening 2 at the planned opening position on the upper surface of the bag body 3, and when the sealing label 7 is first peeled off and opened, A portion surrounded by the cut line 10 is cut out as an opening piece 11, and a takeout port 2 is formed at the trace. The cut opening piece 11 is attached to the sealing label 7 via the pressure sensitive adhesive 6.

  The sealing label 7 has a size sufficient to cover the takeout port 2 of the bag body 3 and the opening 15 formed in the reinforcing sheet 5 corresponding to the takeout port 2. It is made of a shape-retaining sheet such as a plastic sheet, and is detachably attached to the upper surface of the reinforcing sheet 5 of the bag body 3 via a pressure-sensitive adhesive 6. The sealing label 7 is provided with a non-peeling part 12 on the base side and a knob part 13 on the opposite side. At the time of peeling, the knob label 13 is held by pulling the sealing label 7 toward the non-peeling part 12 side. At the time of wearing, the sealing label 7 is pressed to the bag body 3 side while moving from the non-peeling portion 12 side to the knob portion 13 side. For this reason, the direction which connects the non-peeling part 12 and the knob | pick part 13 is the sticking peeling direction of the sealing label 7, and the sealing label 7 is long in the sticking peeling direction.

  The non-peeling portion 12 is configured such that the pressure-sensitive adhesive 6 on the base side of the sealing label 7 is difficult to peel from the upper surface of the bag body 3 by providing cut portions 14 on both sides of the sealing label 7 in the width direction. is there. The knob 13 protrudes outward from a substantially central portion in the width direction of the sealing label 7. In addition, you may arrange | position the knob | pick part 13 in other positions, such as providing in the one end side of the width direction. The sealing label 7 is coated with a pressure sensitive adhesive 6 on substantially the entire surface excluding the knob 13 as shown by hatching in FIG.

  The reinforcing sheet 5 is formed so that the upper surface side of the bag body 3 is removed from the top of the bag body 3 so that wrinkles or the like are not generated around the outlet 2 of the bag body 3 even when the remaining amount of the wet sheet 8 in the bag body 3 is reduced. The outer peripheral side of the outlet 2 of the bag body 3 via the pressure-sensitive adhesive 4 is used to reinforce the outer periphery of the bag 2 and is made of a plastic sheet having shape retention and elasticity that is thicker than the packaging film. Affixed to the top surface.

  The reinforcing sheet 5 is smaller than the upper surface of the bag body 3 and larger than the sealing label 7, for example, a substantially rectangular shape having a size approximately equal to or slightly smaller than the upper surface of the laminated body 9 in the bag body 3. In addition, substantially the entire circumference protrudes outward from the outer circumference of the sealing label 7. In addition, although the knob | pick part 13 has come out outside the reinforcement sheet 5, you may provide so that it may be settled in the reinforcement sheet 5. FIG. In addition, the reinforcing sheet 5 has such a width that both sides in a direction (width direction) substantially orthogonal to the sticking / peeling direction (length direction) of the sealing label 7 come out of the sealing label 7, and on the non-peeling portion 12 side of the sealing label 7. The end edge may substantially coincide with the sealing label 7.

  An opening 15 corresponding to the take-out port 2 of the bag body 3 is formed in the reinforcing sheet 5, and a plurality of embossed portions 16 are formed in the circumferential direction at predetermined intervals in the inner and outer directions on the outer peripheral side of the opening 15. Yes. The opening 15 is slightly larger than the takeout port 2 so that the takeout port 2 is accommodated inside.

  The embossed portion 16 of the reinforcing sheet 5 is distributed substantially evenly from the sticking region 18 corresponding to the sealing label 7 to the outer peripheral side thereof in substantially the entire outer peripheral side of the opening 15 excluding the non-peeling portion 12 of the sealing label 7. Is provided. The reinforcing sheet 5 has an adhesive region 18 having a predetermined width on the entire outer periphery of the opening 15, and the sealing label 7 is adhered to the adhesive region 18 via the pressure sensitive adhesive 6. The embossed portion 16 is disposed across the sticking area 18 and the outer peripheral area of the sticking area 18.

  The embossed portion 16 has a cross-sectional shape in which the pressure-sensitive adhesive 4 side is recessed in an arc shape upward, and one or more of the plurality of embossed portions 16 on the inner peripheral adhesive region 18 side are openings 15. It is an endless ellipse that surrounds the entire circumference. The embossed portion 16 has a straight portion 16 a disposed in the longitudinal direction on both sides in the width direction of the opening 15, and arc portions 16 b at both ends thereof, and is provided substantially concentrically with respect to the oval opening 15. ing.

  The pressure-sensitive adhesive 4 is applied to the reinforcing sheet 5 on substantially the entire surface of the bag body 3 side including the embossed portion 16, and the reinforcing sheet 5 is attached to the pressure-sensitive adhesive 4 at least at the adhesive portion 19 between the embossed portions 16. It is affixed on the upper surface of the bag body 3. Moreover, in the sticking area | region 18 of the sealing label 7, the sealing label 7 is stuck to the reinforcement sheet 5 via the pressure sensitive adhesive 6 at the sticking part 20 between the top part of the embossing part 16 and the embossing part 16 inside and outside. Yes. Note that the sticking portion 19 is continuously formed on the entire circumference surrounding the take-out port 2, and the sticking portion 20 is continuously formed on the entire circumference surrounding the opening 15.

  There is no embossed portion 16 on the non-peeling portion 12 side of the reinforcing sheet 5, and the reinforcing sheet 5 corresponding to the non-peeling portion 12 is a flat flat portion 17. For this reason, in the non-peeling part 12, the sticking area with respect to the bag main body 3 of the reinforcement sheet 5 and the sticking area with respect to the reinforcing sheet 5 of the sealing label 7 are large.

  The embossed portion 16 is formed by embossing the reinforcing sheet 5 with a thermoforming roll or the like. Further, the pressure-sensitive adhesive 4 is applied to the reinforcing sheet 5 in the concave portion of the embossed portion 16, but the pressure-sensitive adhesive 4 in the concave portion may be omitted. The reinforcing sheet 5 may be adhered to the bag body 3 and the sealing label 7 through the pressure-sensitive adhesives 4 and 6 on the substantially entire surface including the embossed portion 16.

  When the laminate 9 of the wet sheet 8 is packaged, the reinforcing sheet 5 with the embossed portion 16 and the sealing label 7 are pasted with the pressure-sensitive adhesive 6, and the reinforcing sheet 5 is attached to the pressure-sensitive adhesive 4. It sticks to the predetermined position of the packaging film used for the bag main body 3 via. At this time, the opening 15 of the reinforcing sheet 5 is attached in accordance with the planned opening of the packaging film take-out port 2. Then, the laminated body 9 of the wet sheet 8 may be supplied on the packaging film in accordance with the attachment position of the reinforcing sheet 5 and the like, and the packaging film may be formed by pillow packaging and packaged in the bag body 3.

  When using the wet sheet 8, the pick-up portion 13 is held and the take-out label 2 is opened while pulling the sealing label 7, and then the wet sheet 8 in the bag body 3 is taken out from the take-out opening 2. At the time of the first opening, since the inner part of the tear line 10 on the upper surface of the bag body 3 is stuck to the sealing label 7 via the pressure sensitive adhesive 6, it is separated by the tear line 10 according to the peeling of the sealing label 7. The take-out port 2 is opened separately from the upper surface of the bag body 3. And the opening piece 11 corresponding to the taking-out port 2 remains attached to the sealing label 7 side.

  After the wet sheet 8 is taken out, for example, the sealing label 7 is pressed to the upper surface side of the bag body 3 while sliding a finger from the non-peeling portion 12 side of the sealing label 7 to the gripping portion 13 side. The pressure sensitive adhesive 6 is attached to the upper surface of the bag body 3 and sealed.

  In this case, since the plurality of embossed portions 16 are formed on the outer peripheral side of the opening 15 of the reinforcing sheet 5, the embossed portion 16 increases the rigidity of the entire reinforcing sheet 5. The reinforcing effect on the outer peripheral side of the take-out port 2 is improved. For this reason, even when the remaining amount of the laminate 9 of the wet sheet 8 is reduced, it is possible to keep the peripheral portion of the outlet 2 of the bag body 3 in a predetermined shape, and the remaining amount of the laminate 9. The pressure-sensitive adhesive 6 of the sealing label 7 causes the embossed portion 16 of the reinforcing sheet 5 by pressing the sealing label 7 while sliding a finger from the non-peeling portion 12 side to the picking portion 13 side. It is possible to easily and reliably seal the take-out port 2 of the bag body 3 with the sealing label 7.

  Therefore, by reinforcing the bag body 3 with the reinforcing sheet 5 with the embossed portion 16, it is not necessary to use a thick material with high rigidity for the reinforcing sheet 5, and sufficient reinforcement is made while using a relatively thin reinforcing sheet 5. Since an effect can be obtained, an increase in manufacturing cost, an increase in weight, and the like can be suppressed as compared with the case where a thick material having high rigidity is used.

  Moreover, since the embossed part 16 is formed on both sides of the sealing label 7 in the width direction in addition to forming the embossed part 16 in the sticking area 18 of the sealing label 7 in the reinforcing sheet 5, only in the sticking area 18. Compared with the case where the embossed portion 16 is provided, the reinforcing effect by the embossed portion 16 can be sufficiently ensured. In addition, since there are a plurality of linear portions 16a continuous along the longitudinal direction on both sides of the opening 15 in the width direction, the reinforcing sheet 5 is formed by the embossed portions 16 as compared with the case where the embossed portions 16 that are long in the width direction are provided. The rigidity of the can be further secured.

  Furthermore, the sticking part 19 where the pressure sensitive adhesive 4 of the reinforcing sheet 5 sticks to the bag body 3 and the adhesive part 20 where the pressure sensitive adhesive 6 of the sealing label 7 sticks to the reinforcing sheet 5 are all on the outer periphery of the opening 15. Since it continues to the periphery, the sealing performance is not impaired even though the reinforcing sheet 5 has the embossed portion 16.

  In the non-peeling portion 12 that makes it difficult to peel the sealing label 7, the reinforcing sheet 5 is a flat portion 17 without the embossed portion 16, and the flat portion 17 is pasted on the bag body 3 via the pressure-sensitive adhesive 4. Since the sealing label 7 is stuck on the flat portion 17 of the reinforcing sheet 5 via the pressure sensitive adhesive 6, the embossed portion 16 is provided on substantially the entire reinforcing sheet 5 including the non-peeling portion 12. Compared with the case, the adhesion area of the pressure sensitive adhesives 4 and 6 can be sufficiently secured.

  FIG. 6 illustrates a second embodiment of the present invention. In this embodiment, the reinforcing sheet 5 is formed with a plurality of embossed portions 16 in the circumferential direction on the outer periphery of the opening 15, and the embossed portions 16 are connected to the non-peeled portion 12 side of the sealing label 7. The shape is different on the side of the mama portion 13. For example, the arc portion 16b is formed substantially concentrically with respect to the opening 15 on the non-peeling portion 12 side, and the left and right linear portions 16c are formed in the middle of the width direction of the sealing label 7 on the knob portion 13 side. It has become. Other configurations are the same as those of the first embodiment.

  Thus, by providing the embossed part 16 corresponding to the knob part 13 side with the straight line part 16c in the left-right direction, the rigidity of the central part in the width direction of the reinforcing sheet 5 on the knob part 13 side is further improved, and the sealing is performed. When the label 7 is pressed, the pressure sensitive adhesive 6 can be reliably attached to the reinforcing sheet 5.

  Accordingly, when providing the embossed portion 16 in the circumferential direction on the reinforcing sheet 5, it is necessary to provide each straight line portion 16 c at a location where the rigidity needs to be greater than that of other portions, or increase the number thereof as necessary. You may change suitably the shape of the embossing part 16, a number, a direction, etc. for every.

  7 and 8 illustrate a third embodiment of the present invention. In this embodiment, the reinforcing sheet 5 is formed with a plurality of embossed portions 16 in the circumferential direction on the outer periphery of the opening 15 in the circumferential direction, and the flat portion of the reinforcing sheet 5 corresponding to the non-peeled portion 12 of the sealing label 7. An embossed portion 16 is also formed on the outer periphery of 17 in the circumferential direction. And the embossed part 16 is comprised by the linear part 16a along the longitudinal direction of the opening 15, and the linear part 16c which connects the both ends side to the width direction of the opening 15, and is continuing substantially rectangular shape. Other configurations are the same as those of the first and second embodiments.

  In this way, the reinforcing sheet 5 is provided with the embossed portion 16 on the outer periphery of the take-out port 2 and also provided with the embossed portion 16 on the outer peripheral side of the flat portion 17 corresponding to the non-peeled portion 12. The rigidity of the reinforcing sheet 5 at the outer peripheral portion can be improved.

  FIG. 9 illustrates a fourth embodiment of the present invention. The pressure-sensitive adhesive 4 of the reinforcing sheet 5 is continuously adhered to the bag body 3 and the pressure-sensitive adhesive 6 of the sealing label 7 is continuously adhered to the reinforcing sheet 5 in the circumferential direction at the outer periphery of the outlet 2 and the opening 15. If there is, it is also possible to form a large number of embossed portions 16 on the reinforcing sheet 5 independently in the sticking and peeling direction as shown in FIGS. Other configurations are the same as those of the first embodiment.

  A large number of embossed portions 16 are arranged in a substantially concentric manner along the outer periphery of the opening 15 in the reinforcing sheet 5 in FIG. In the reinforcing sheet 5 of FIGS. 9B and 9C, a large number of embossed portions 16 are arranged on the outer periphery of the opening 15 in a staggered manner so as to be distributed substantially uniformly. The embossed portion 16 in FIG. 9B is formed long in the longitudinal direction of the sealing label 7, and the embossed portion 16 in FIG. 9C is formed in a spherical shape having no directivity in the longitudinal direction and the width direction.

  In addition, the endless embossed portion 16 in the circumferential direction shown in the first to third embodiments is combined with any one type, two types, or three types of embossed portions 16 of FIGS. 9 (A) to (C). It is also possible to provide them.

  FIG. 10 illustrates a fifth embodiment of the present invention. The embossed portion 16 of the reinforcing sheet 5 may be configured to have a convex shape that protrudes downward as shown in FIGS. . Also in these cases, the rigidity of the reinforcing sheet 5 can be easily secured by the embossed portion 16. Other configurations are the same as those of the first embodiment.

  In the reinforcing sheet 5 of FIG. 10A, the embossed portion 16 is formed in a convex shape in which the pressure-sensitive adhesive 4 side protrudes in an arc shape, and the flat portion between the top side of the convex embossed portion 16 and the embossed portion 16 is formed. The part, or the substantially whole surface on the lower surface side of the embossed part 16 and the flat part is a sticking part 19 between the reinforcing sheet 5 and the bag body 3. The pressure-sensitive adhesive 6 of the sealing label 7 is stuck to the sticking portion 20 of the flat portion between the embossed portions 16 of the reinforcing sheet 5.

  Further, in the reinforcing sheet 5 of FIG. 10 (B), the embossed portion 16 has a concave and convex shape in which the concave portion 21a and the convex portion 21b are continuous in a wave shape, and the lower side of the embossed portion 16 of the reinforcing sheet 5 is sensed. The pressure adhesive 4 is adhered to the upper surface of the bag body 3, and the pressure-sensitive adhesive 6 below the sealing label 7 is adhered to the upper surface of the reinforcing sheet 5. In the reinforcing sheet 5 of FIG. 10C, the concave portion 21 a and the convex portion 21 b of the embossed portion 16 are provided in the inner and outer directions of the opening 15 at a predetermined interval.

  11 and 12 illustrate a sixth embodiment of the present invention. In the reinforcing sheet 5 of this embodiment, substantially the entire sticking region 18 including the non-peeling portion 12 of the sealing label 7 is a flat portion 17, and the embossed portion is formed on the reinforcing sheet 5 on the outer peripheral side of the sticking region 18. 16 is continuously formed in the circumferential direction. A sealing label 7 is detachably attached to the flat portion 17 of the reinforcing sheet 5 via a pressure sensitive adhesive 6. A plurality of embossed portions 16 are continuously formed in the circumferential direction on the outer peripheral side of the sticking region 18 so as to ensure a predetermined rigidity. Other configurations are the same as those of the first embodiment.

  As described above, the embossed portion 16 of the reinforcing sheet 5 may be provided on the outer periphery of the sticking region 18 of the sealing label 7. In this case, since it is not necessary to stick the sealing label 7 to the embossed portion 16 side of the reinforcing sheet 5 via the pressure sensitive adhesive 6, the shape of the embossed portion 16 is mainly intended to ensure the rigidity of the reinforcing sheet 5. The sequence can be determined. Further, the sticking area 18 is a flat portion 17 without the embossed portion 16, and the rigidity of the reinforcing sheet 5 on the flat portion 17 side is improved by the embossed portion 16 on the outer periphery thereof, so that poor adhesion of the sealing label 7 can be easily prevented. be able to.

  13 and 14 illustrate a seventh embodiment of the present invention. In this embodiment, as shown in FIG. 13, a reinforcing sheet 5 that reinforces the outer peripheral side of the oval take-out port 2 is stuck, and a sealing label 7 that opens and closes the take-out port 2 is peeled on the reinforcing sheet 5. The sealing label 7 has a non-peeling portion 12 on one end side in the width direction of the outlet 2 and a knob portion 13 on the other end side. The reinforcing sheet 5 is fixed to the upper surface of the bag body 3 by hot melt bonding, other appropriate bonding, welding, or the like, and a takeout port 12 and an embossed portion 16 are formed across both.

  In this case, when the laminate 9 of the wet sheet 8 is packaged, the reinforcing sheet 5 is attached to the packaging film 22 as shown in FIGS. What is necessary is just to form. For example, as shown in FIG. 14A, first, the reinforcing sheet 5 is fixed to the packaging film 22 by hot melt bonding, other appropriate bonding, or welding, and then the reinforcing sheet 5 and the packaging film 22 are thermoformed rolls. The embossed portion 16 is formed as shown in FIG. In addition, before the processing of the embossed part 16, at the time of processing, or after the processing, the cut line 10 is put across the packaging film 22 and the reinforcing sheet 5.

  Next, as shown in FIG. 14 (C), the sealing label 7 is stuck on the reinforcing sheet 5 via the pressure sensitive adhesive 6, and then the wet sheet 8 is placed at a position corresponding to the reinforcing sheet 5 of the packaging film 22. The laminated body 9 is supplied and packaged in the same manner as before.

  Thus, after sticking the reinforcing sheet 5 to the packaging film 22, the packaging film 22 and the reinforcing sheet 5 can be embossed to form the embossed portion 16. Further, if the cut line 10 is formed before or after embossing, when the sealing label 7 is peeled and opened for the first time, the portion of the reinforcing sheet 5 surrounded by the cut line 10 is cut as the opening piece 11. be able to.

  In this case, the opening piece 11 constituted by the reinforcing sheet 5 and the packaging film 22 adheres to the sealing label 7. By opening and closing the sealing label 7 in the width direction of the outlet 2, the width of the opening piece 11 is increased. Therefore, the opening piece 11 does not obstruct the opening and closing of the sealing label 7.

  In addition, you may make it the sealing label 7 open and close in the longitudinal direction. Alternatively, the embossed portion 16 may be processed after the opening 15 is formed in the reinforcing sheet 5 in advance and the reinforcing sheet 5 with the opening 15 is fixed to the packaging film 22. Further, the embossed portion 16 of the reinforcing sheet 5 may be provided outside the sticking region 18 of the sealing label 7.

  17 and 18 illustrate a ninth embodiment of the present invention. This embodiment shows a case where it is adopted for a pocket-type packaging bag 1, and a reinforcing sheet 5 is stuck on the upper surface of a flat bag body 3 via a pressure sensitive adhesive 4, and a sealing label 7 is placed on the reinforcing sheet 5. Is attached via a pressure-sensitive adhesive 6. The reinforcing sheet 5 and the sealing label 7 have substantially the same width and length. An embossed portion 16 is formed on the reinforcing sheet 5 over substantially the entire area excluding the non-peeled portion 12. The embossed portion 16 has a cross-sectional shape that is recessed in a circular arc shape on the lower side, and is continuously disposed in the circumferential direction on the outer periphery of the opening 15, but may have other shapes and configurations.

  As described above, even in the case of the pocket type in which the number of the wet sheets 8 stacked is relatively small, the peripheral portion of the take-out port 2 of the bag body 3 is reinforced by the reinforcing sheet 5 having the embossed portion 16, and the sealing is provided on the reinforcing sheet 5. The label 7 may be attached. In this case, the sizes of the reinforcing sheet 5 and the sealing label 7 may be substantially the same, and the edges may be substantially coincident.

  As mentioned above, although each embodiment of this invention was illustrated, this invention is not limited to each embodiment, A various change is possible in the range which does not deviate from the meaning. For example, in the embodiment, the laminated body 9 of the wet sheet 8 is illustrated as the contents to be packaged, but other than the wet sheet 8 may be used. For example, it is not limited to a wet state, and may be a dry state.

  The reinforcing sheet 5 desirably protrudes outward from the sealing label 7 on both sides in a direction substantially perpendicular to the sticking / peeling direction of the sealing label 7, and when the embossed portion 16 is provided on the reinforcing sheet 5, The embossed portion 16 may be disposed on substantially the entire circumference of the outer periphery, but it is only necessary that the embossed portions 16 are at least on both sides in the width direction of the take-out port 2.

  Moreover, when the embossed part 16 is provided corresponding to the sticking area | region 18 of the sealing label 7, the reinforcement sheet 5 of the sticking area | region 18 of the sealing label 7 can be reinforced directly. For this reason, the embossed part 16 should just exist in the part corresponding to the sticking area | region 18 of the reinforcement sheet 5 at least. Conversely, when the reinforcing sheet 5 is reinforced at the outer periphery of the sticking region 18 of the sealing label 7, the embossed portion 16 may be at least at the outer periphery of the sticking region 18.

  In order to increase the rigidity of the reinforcing sheet 5, it is desirable to distribute the embossed portions 16 substantially uniformly over the entire surface of the reinforcing sheet 5. However, in order to ensure a sufficient sticking area of the sealing label 7, the sealing label 7 It is desirable to provide an embossed portion 16 in a range excluding the non-peeling portion 12 and to form the reinforcing sheet 5 in the non-peeling portion 12 in a flat shape.

  The cross-sectional shape, arrangement, and the like of the embossed portion 16 to be formed on the reinforcing sheet 5 can be appropriately changed. In this case, the sticking surface on which the sealing label 7 is stuck on the reinforcing sheet 5 It is necessary to provide it continuously in the circumferential direction.

  An embossed portion 16 is formed in advance on the reinforcing sheet 5, and the reinforcing sheet 5 with the embossed portion 16 is attached to the bag body 3 or a packaging film constituting the bag body 3 with a pressure sensitive adhesive 4, 6, etc. The sealing label 7 may be attached to the reinforcing sheet 5, or the reinforcing sheet 5 with the embossed portion 16 and the sealing label 7 are attached, and then the reinforcing sheet 5 is attached to the bag body 3 or the bag body 3. You may stick to the packaging film to comprise by the pressure sensitive adhesives 4 and 6 and others. Alternatively, the reinforcing sheet 5 may be attached to a film constituting the bag body 3, and then the embossed part 16 may be formed by embossing the reinforcing sheet 5 and the packaging film.

  Although the embossed portion 16 may be provided on the sealing label 7, it is desirable that the embossed portion 16 in that case is distributed substantially evenly in the region excluding the non-peeled portion 12. Further, it is desirable that the embossed portion 16 of the sealing label 7 is arranged independently in the sticking / peeling direction of the sealing label 7 so as not to cause a problem that a part of the embossed portion 16 is bent at the time of peeling.
