<First embodiment>
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a top view of a packaging bag 1 according to a first embodiment. FIG. 2 is a sectional view taken along line AA in FIG.

The packaging bag 1 includes a storage section 10 that stores wet tissues 30 as contents, and a lid seal 12. A plurality of wet tissues 30 are stored in the storage section 10 in a vertically stacked manner. The wet tissue 30 is formed by impregnating water, a humectant, etc. with water-resistant paper or nonwoven fabric. Further, the wet tissue 30 is of a fragrance-free type with no added fragrance.

The storage portion 10 is formed by stacking a substantially rectangular top sheet 21, bottom sheet 22, and gusset sheet 23 and thermally bonding a seal portion 15 at the periphery. The top sheet 21, the bottom sheet 22, and the gusset sheet 23 are made of a laminated film 40, which will be described later.

The top sheet 21 forms the top surface of the storage section 10 and has a lid part 11a that can be cut out along an oval half-cut line 11b. An outlet 11 (see FIG. 4) is formed by peeling off the lid 11a. The lower sheet 22 faces the upper sheet 21 and forms the lower surface of the storage section 10.

The gusset sheet 23 is sandwiched between the top sheet 21 and the bottom sheet 22 by folding the inner layer 43 of a laminated film 40 (described later) in half with the inner layer 43 facing outward. The periphery of the gusset sheet 23 is thermally bonded to the top sheet 21 and the bottom sheet 22 by the gusset seal portion 15b (see FIG. 2). In the area of the seal portion 15 excluding the gusset seal portion 15b, the upper sheet 21 and the lower sheet 22 are thermally bonded.

By providing the gusset sheet 23, the capacity of the storage section 10 increases and more wet tissues 30 can be stored. Moreover, by spreading the gusset sheet 23 to form a bottom surface, the packaging bag 1 can be made to stand on its own.

The lid seal 12 is made of, for example, polyethylene terephthalate, nylon, or polypropylene.

The lid seal 12 has adhesive applied to its lower surface and has re-adhesive properties. As the adhesive, an acrylic adhesive, a urethane adhesive, or a silicone adhesive can be used. In addition, various other adhesive resins may also be used.

Moreover, the lid seal 12 is formed into a substantially rectangular shape. A portion of the tip of the lid seal 12 protrudes to form a protrusion 12a.

No adhesive is applied to the lower surface of the protrusion 12a, forming a non-adhesive area. Thereby, the user can easily peel off the lid seal 12 from the packaging bag 1 by grasping the protrusion 12a.

The lid seal 12 covers the score line 11b and is adhered to the lid portion 11a and the periphery of the lid portion 11a. When the lid seal 12 is peeled off from the packaging bag 1, the lid portion 11a adhered to the lid seal 12 is broken along the score line 11b. As a result, an oval outlet 11 is opened in the upper surface of the packaging bag 1 (see FIG. 4). Further, the lid seal 12 can re-adhere after being peeled off from the periphery of the outlet 11 to reseal the outlet 11.

Further, a chuck member 16 is provided at a side end portion of the storage portion 10. The chuck member 16 is made of resin and is arranged on the inner surface of the storage section 10 . Specifically, the chuck member 16 includes a male portion 16a, a female portion 16b, a first base portion 16c, and a second base portion 16d. The male part 16a and the first base part 16c are integrally molded, and the female part 16b and the second base part 16d are integrally molded.

The first base portion 16c is formed in a band shape and is thermally bonded to the lower surface of the top sheet 21. The male portion 16a is provided to protrude from the lower surface of the first base portion 16c. The second base portion 16d is formed into a band shape and is thermally bonded to the upper surface of the lower sheet 22. The female portion 16b projects from the upper surface of the second base portion 16d and engages with the male portion 16a.

By engaging the male part 16a and the female part 16b, the chuck member 16 is closed and the unsealed storage section 10 is sealed. By releasing the engagement between the male portion 16a and the female portion 16b, the chuck member 16 is opened, and the opening 10a (see FIG. 4) of the storage portion 10 is opened.

On the outer circumferential side of the chuck member 16, opening start portions 15a are provided at both end edges of the seal portion 15 extending along opposing long sides of the storage portion 10. The unsealing starting part 15a consists of a V-notch which is a cut for opening. Thereby, the user can easily tear and open the seal part 15 starting from the unsealing starting part 15a, and an opening 10a (see FIG. 4) is formed at the side end of the storage part 10. Further, the user can recognize the starting point for opening the packaging bag 1 using the opening start portion 15a as a landmark. In addition, the unsealing starting part 15a may be formed by an I notch or a U notch, or may be formed by a scar group consisting of a plurality of fine puncture holes.

FIG. 3 is a cross-sectional view showing the layer structure of the laminated film 40 constituting the packaging bag 1. As shown in FIG. In the laminated film 40 constituting the packaging bag 1, an intermediate layer 42 is laminated between an outer layer 41, which is the outermost layer, and an inner layer 43 having thermal adhesive properties.

The outer layer 41 provides the packaging bag 1 with sealing properties, puncture resistance (pinhole resistance), and the like. For the outer layer 41, any known resin can be selected, such as polyethylene, polypropylene, polyethylene terephthalate, polyester, polyamide, polyvinyl chloride, and the like. Alternatively, the outer layer 41 may be formed by laminating a plurality of these resins.

The intermediate layer 42 has water vapor barrier properties and can prevent water vapor and oxygen from entering the packaging bag 1 from the outside, thereby preventing deterioration of the wet tissue 30. Further, it is possible to prevent the moisturizing agent and the like contained in the wet tissue 30 from permeating to the outside of the packaging bag 1 and drying the wet tissue 30. The intermediate layer 42 is formed of, for example, a deposited film of a metal such as aluminum, or a deposited film of an inorganic oxide such as aluminum oxide or silicon oxide.

The inner layer 43 may be any heat-adhesive resin that can be melted by heat and can fuse the facing laminated films 40 to each other, and can be arbitrarily selected from polyethylene, propylene, etc., for example.

FIG. 4 is an explanatory diagram illustrating how to use the packaging bag 1. The method of using the packaging bag 1 includes an opening process, an addition process, a peeling process, and a resealing process in this order.

In the unsealing step, the storage portion 10 is torn along the chuck member 16 starting from the unsealing starting portion 15a. As a result, the outer peripheral side of the chuck member 16 in the storage section 10 is cut off, and an opening 10a is opened at one end of the storage section 10.

Next, in the addition step, the chuck member 16 is opened and the perfume (including cologne) desired by the user is sprayed or dropped from the opening 10a to add the perfume to the entire wet tissue 30. At this time, since perfume is added from the side of the wet tissues 30 that overlap in the vertical direction, each wet tissue 30 can be impregnated with perfume. After adding the perfume, the chuck member 16 is closed to seal the storage section 10.

Next, in the peeling step, the lid seal 12 is peeled off from the packaging bag 1 by grasping the protrusion 12a. At this time, the top sheet 21 is cut along the score line 11b, and the lid portion 11a is peeled off while remaining adhered to the adhesive surface of the lid seal 12. As a result, the outlet 11 is opened on the top surface of the packaging bag 1, and the wet tissues 30 to which perfume has been added can be easily taken out sequentially from the outlet 11. At this time, since the wet tissue 30 contains the perfume desired by the user, it is possible to use the wet tissue 30 with a scent that matches the user's preference.

Next, when the wet tissue 30 is taken out from the outlet 11, a resealing process is performed, and the outlet 11 is resealed with the lid seal 12. Thereby, drying of the wet tissue 30 can be prevented. Note that the addition step may be performed after the peeling step and the resealing step.

According to this embodiment, since the chuck member 16 is provided at the side end of the storage section 10 in which the wet tissue 30 is stored, the user can add desired perfume by opening the side end of the storage section 10. . Thereby, it is possible to use the wet tissue 30 with a scent that matches the user's preference, and the user can feel satisfied. At this time, since perfume is added from the side of the wet tissues 30 that overlap in the vertical direction, each wet tissue 30 can be impregnated with perfume.

Further, the seal portion 15 has an unsealing start portion 15a on the outer peripheral side of the chuck member 16. Thereby, the opening 10a of the storage portion 10 can be easily opened on the outer peripheral side of the chuck member 16.

Furthermore, since the wet tissue 30 stored in the storage section 10 is of a fragrance-free type, it is possible to prevent the fragrance of the perfume added from the opening 10a from deteriorating.

Additionally, there is an unsealing process in which the outer circumferential side of the chuck member 16 of the storage section 10 is cut to form an opening 10a, and the chuck member 16 is opened, perfume is added to the wet tissue 30 through the opening 10a, and the chuck member 16 is closed. and a peeling step of peeling off the lid seal 12 to make it possible to take out the wet tissue from the outlet 11. As a result, the additive can be added to the entire wet tissue 30 while reducing bias, and the wet tissue 30 to which the additive has been added can be easily taken out from the outlet 11.
