Description

The present invention relates to a packaging body.

Conventionally, wet tissue packages that contain multiple wet tissues and pocket tissue packages that contain multiple tissues are known. Such wet tissue packages and pocket tissue packages are often carried and used when going out.

However, when using wet tissues or tissue paper contained in a package while out and about, if there is no trash can or the like nearby, it can be difficult to dispose of the used wet tissues or tissue paper. In response to this, a package has been proposed that is provided with a used tissue paper storage section for storing used wet tissues (see, for example, Patent Document 1).

The packaging body disclosed in Patent Document 1 comprises a packaging body in which multiple wet tissues are stored, and a used wet tissue storage section provided on the outer surface side of the packaging body. This packaging body comprises a first seal section formed by joining a pair of first side edge sides of a sheet member to each other, and a pair of second seal sections formed by respectively joining a pair of side edge sides extending in a direction intersecting the pair of first side edges of the sheet member in a state in which the first seal sections are formed. The used wet tissue storage section is composed of the first seal section, a first seal extension section formed by extending from the first seal section in a direction intersecting the extension direction of the first side edges, and the sheet member that constitutes this packaging body.

JP 2011-168322 A

For the packaging proposed in Patent Document 1, from a hygienic standpoint, an outer bag is required to ensure the virginity of the lid sheet at the opening until the user is about to use the product. Therefore, the technology disclosed in Patent Document 1 requires extra resin for the outer bag.

The present invention therefore relates to a package that does not require an outer bag to ensure the virginity of the lid sheet at the opening, making it possible to reduce the amount of resin used.

The present invention relates to a package.
The packaging body includes a first seal portion formed by joining sheets of soft packaging material together;

a second surface portion opposed to the first surface portion;
a lid sheet attached to the first surface portion so as to close the opening;
It is preferable that the portable terminal further comprises a cover sheet removably attached so as to cover at least a portion of the first surface portion.
The cover sheet preferably has an adhesive-coated portion on one side thereof, the adhesive being applied so that a portion remains uncoated with adhesive.
It is preferable that the packaging body is configured such that by attaching the cover sheet peeled off from the first surface portion to the second surface portion, an item can be contained in the space defined by the cover sheet and the second surface portion through the non-adhesive coated portion.

The present invention also relates to another package.
The packaging body includes a first seal portion formed by joining sheets of soft packaging material together;
a pair of second sealed portions formed by joining a pair of end regions of the soft packaging material in a state in which the first sealed portion is formed, the end regions extending in a direction intersecting the first sealed portion;
A first surface portion;
a second surface portion having a first seal portion and facing the first surface portion;

Hereinafter, the present invention will be described based on preferred embodiments with reference to the drawings.
1 and 2 is formed from a sheet-like soft packaging material 10. The package 1 is formed by joining a pair of side regions of a single rectangular soft packaging material 10 in a partially overlapping state to form the soft packaging material 10 into a cylindrical shape, and then joining end regions including two open ends of the cylindrical soft packaging material 10.

The packaging body 1 has a generally rectangular parallelepiped shape and has a first direction X and a second direction Y perpendicular to the first direction X. The first direction X coincides with the extension direction of the first seal portion 21 described below, and in this embodiment, also coincides with the longitudinal direction of the packaging body 1. The second direction Y is perpendicular to the extension direction of the first seal portion 21, and in this embodiment, also coincides with the lateral direction of the packaging body 1.

1 and 2, the package 1 formed from the soft packaging material 10 has a storage section 5 capable of storing an object 2. As shown in Fig. 2, the storage section 5 has a storage space 51 capable of storing the object 2. A stack 2S in which a plurality of objects 2 are stacked in an unfolded state or folded into a predetermined shape such as a rectangle is stored in the storage section 5.
Examples of the storage object 2 include a fiber sheet such as a nonwoven fabric impregnated with a liquid such as lotion, milky lotion, beauty essence, face wash, makeup remover, hair wash, disinfectant, detergent, activator water, alcohol-containing liquid, water, etc. Alternatively, a dry sheet such as tissue paper can be used as the storage object 2.

The storage section 5 has a first surface portion F1 and a second surface portion F2, which is the surface opposite to the first surface portion F1. The storage section 5 has a pair of third surfaces F3, F3 between the opposing first surface portion F1 and second surface portion F2. The pair of third surfaces F3, F3 face each other in the second direction Y. The storage section 5 has each surface of the first surface portion F1, the second surface portion F2, and the pair of third surfaces F3, F3 formed from soft packaging material 10.

The storage section 5 has a linear fold extending in the first direction X on the third surface F3, formed in the center of the height direction of the third surface F3 (not shown), and the fold is folded inward in the second direction Y to form a valley fold, making it possible to fold the soft packaging material 10 forming the third surface F3 into a V shape. In this way, the storage section 5 has a gusset shape on the pair of third surfaces F3, F3.

As shown in Figures 1 and 2, the storage section 5 has an opening 3 for removing the storage object 2 on the first surface F1, and a lid sheet 4 for opening and closing the opening 3.

The opening 3 is a through hole penetrating the first surface portion F1 of the soft packaging material 10 and is located at the center of the first surface portion F1. The opening 3 communicates with the storage space 51 of the storage portion 5 for the object 2 to be stored. The object 2 is taken out through the opening 3. The shape of the opening 3 is not particularly limited, and may be, for example, a rectangular, square, circular, or elliptical shape. The opening 3 may be formed at least when the lid sheet 4 is lifted up. Therefore, the opening 3 may not be formed in the package 1 until the lid sheet 4 is lifted up for the first time, and when the lid sheet 4 is lifted up for the first time, a part of the first surface portion F1 is lifted up together with the lid sheet 4, so that the opening 3 is formed for the first time.

The lid sheet 4 covers the entire opening 3 on the outer surface of the first surface F1 and is peelably attached to the first surface F1. The lid sheet 4 can be a seal sheet having an adhesive layer made of an adhesive on the surface facing the first surface F1.
The adhesive layer of the lid sheet 4 is preferably removable. In this case, the adhesive layer can be imparted with removable properties by forming the adhesive layer with an adhesive having removable properties. As such an adhesive, a general-purpose acrylic adhesive is preferable.

2 and 4, the package 1 has a first seal portion 21 formed along a first direction X by joining a pair of side regions of a rectangular soft packaging material 10 in a palm-to-palm shape. The storage section 5 also has a pair of second seal portions 22, 22 at both ends in the first direction X. The second seal portion 22 extends in a direction intersecting the first direction X, specifically in a direction perpendicular thereto. The first seal portion 21 is located between the pair of second seal portions 22, 22.
In the manufacturing process of the package 1, the first sealed portion 21 is a joining portion that forms the rectangular soft packaging material 10 into a cylindrical shape, and joins side regions of the rectangular soft packaging material 10 together along the first direction X on the second surface portion F2 side. That is, the second surface portion F2 includes the first sealed portion 21. The first sealed portion 21 is located approximately at the center of the storage portion 5 in the second direction Y, but the position of the first sealed portion 21 is not limited thereto, and may be formed, for example, at a position offset outward from the center in the second direction Y. The first sealed portion 21 falls down to one side in the second direction Y and contacts the second surface portion F2.
The second sealed portions 22, 22 are joints that close the openings located at both ends of the tubular soft packaging material 10, and together with the first sealed portion 21, form the storage portion 5 having the sealed storage space 51. That is, the second sealed portions 22, 22 are located on both sides of the tubular soft packaging material 10, and are formed in a pair of end regions that have openings.
The first and second sealed portions 22 are formed by, for example, heat sealing.

As the soft packaging material 10 constituting the package 1, a liquid-impermeable sheet material can be used, and for example, a sheet material made of aluminum, a thermoplastic resin film, a thermoplastic resin film vapor-deposited with aluminum, silica, alumina, or the like, a thermoplastic resin film serving as a sealant layer, a laminated film in which an aluminum layer is sandwiched between thermoplastic resin films, or a combination of these can be used. The thermoplastic resin film may be a base film such as a polyethylene terephthalate (PET) film or a nylon film, or may have a laminated structure in which these films are laminated. From the viewpoint of suppressing the seepage or volatilization of the liquid contained in the object to be contained 2 (e.g., wet wipes), it is preferable that the soft packaging material 10 has a laminated structure in which an aluminum sheet, a PET film, or an aluminum layer is laminated. The thermoplastic resin layer in such a laminated structure may be a single layer, or may be a multilayer of two or more layers.

As shown in Figs. 1 and 2, the package 1 includes a cover sheet 40. The cover sheet 40 is removably attached to the first surface F1 so as to cover at least a portion of the first surface F1 before the package 1 is used. For example, the cover sheet 40 is attached to the first surface F1 so as to cover at least the lid sheet 4. With this configuration, the lid sheet 4 is protected by the cover sheet 40 until immediately before use, so that the virginity of the lid sheet 4 is ensured until immediately before the user opens the lid sheet 4. As a result, the outer bag for protecting the package that was conventionally used is no longer necessary, and the amount of synthetic resin used can be reduced.

When a user wishes to use the object 2 contained in the package 1, the user peels the cover sheet 40 off the first surface F1, then opens the lid sheet 4 to expose the opening 3, and picks up the object 2 with his/her fingers through the opening 3 to remove it from the package 1.

As shown in FIG. 1, the cover sheet 40 is attached to the first surface F1 so that each side edge along the longitudinal direction of the cover sheet 40 coincides with each side edge along the longitudinal direction of the first surface F1. Also, the cover sheet 40 is attached to the first surface F1 so that each edge along the lateral direction of the cover sheet 40 coincides with the inner edge 22b (see FIG. 1) of each second seal portion 22. That is, the first surface F1 and the cover sheet 40 are both rectangular with the same dimensions. Therefore, the second surface F2, which is the surface opposite to the first surface F1, and the cover sheet 40 are also rectangular with approximately the same dimensions. In this way, as described later, the space S defined by the cover sheet 40 and the second surface F2 can be maximized, and a large amount of the storage object 2 after use can be stored in the space S.
Such "approximately the same dimensions" includes cases where the vertical width (length in the first direction X) and horizontal width (length in the second direction Y) of the rectangular cover sheet 40 are the same as the vertical width (length in the first direction X) and horizontal width (length in the second direction Y) of the first surface portion F1 and the second surface portion F2, and cases where they are shorter by within 10 mm.
From the viewpoint of more reliably attaching the cover sheet 40 to the first surface F1, the length in the first direction X of the cover sheet 40 of this embodiment is preferably 3 mm or more, more preferably 5 mm or more shorter than the length in the first direction X of the first surface F1. From the same viewpoint as above, the length in the second direction Y of the cover sheet 40 of this embodiment is preferably 1 mm or more, more preferably 3 mm or more shorter than the length in the second direction Y of the first surface F1. By making the cover sheet 40 have such dimensions, the cover sheet 40 can be more reliably attached to the first surface F1 even if the attachment position of the cover sheet 40 is shifted or the heat seal position is shifted during the manufacturing process of the package 1.

As shown in FIG. 3, the dimensions of the cover sheet 40 can be made approximately the same as the vertical width (length in the first direction X) and horizontal width (length in the second direction Y) of the object 2 to be stored, which is a rectangular item such as wet tissue or tissue paper.
Such "approximately the same dimensions" includes cases in which the vertical width (length in the first direction X) and horizontal width (length in the second direction Y) of the rectangular cover sheet 40 are the same as the vertical width (length in the first direction X) and horizontal width (length in the second direction Y) of the object to be contained 2, and cases in which they are shorter by within 10 mm.
When wet tissues or tissue paper are stored in a folded state, the vertical and horizontal widths of the item (the object 2) refer to the dimensions when the item is folded. Setting the dimensions of the cover sheet 40 in this manner allows the user to feel a sense of unity between the cover sheet 40 and the object 2. In addition, the cover sheet 40 has a smaller dimension than the second surface F2, and can be reattached to the planar area of the second surface F2 where the object 2 is present, making it easy to reattach the cover sheet 40 to the second surface F2.

3, from the viewpoint of more reliably attaching the cover sheet 40 to the first surface F1, the length of the cover sheet 40 in the first direction X is preferably 1 mm or more shorter, and more preferably 3 mm or more shorter, than the length of the first direction X of the object to be contained 2. From the same viewpoint as above, the length of the cover sheet 40 in the second direction Y is preferably 1 mm or more shorter, and more preferably 3 mm or more shorter, than the length of the second direction Y of the object to be contained 2. By setting the cover sheet 40 to such dimensions, even if the attachment position of the cover sheet 40 is shifted during the manufacturing process of the package 1, the cover sheet 40 can be more reliably attached to the first surface F1.
The packaging body 1 of the embodiment shown in FIG. 3 differs from the packaging body of the embodiment shown in FIG. 1 in that the third surface portion F3 does not have a gusset shape and has a flattened cylindrical shape.

3, when the cover sheet 40 is a rectangle smaller than the dimensions of the first surface F1 and the second surface F2, the cover sheet 40 is preferably attached to the first surface F1 in the package 1 before use so as to be spaced inward in the first direction X from the inner edge 22b of the second sealed portion 22. That is, it is preferable to provide a gap C1 between the cover sheet 40 and the inner edge 22b of the second sealed portion 22 in the first direction X (see FIG. 3).
A plurality of packages 1 are packed in a packing box such as a cardboard box. The packages 1 may be packed in the packing box with one second seal portion 22 facing downward and the other second seal portion 22 facing upward. In this packed state, the object 2 to be contained is shifted downward, so that the lower part of the package 1 near the second seal portion 22 is easily crushed. By providing the above-mentioned interval C1 against such crushing, the lower part of the cover sheet 40 can be prevented from wrapping around under the object 2 to prevent the cover sheet 40 from twisting or wrinkling. From the viewpoint of further preventing the cover sheet 40 from twisting or wrinkling in the packed state, the interval C1 (see FIG. 3) between the cover sheet 40 and the inner end edge 22b of the second seal portion 22 in the first direction X is preferably provided on one side of the second seal portion 22, and more preferably on the side of the second seal portion 22 that is arranged on the lower side in the packed state. The gap C1 may be provided on each side of the pair of second seal portions 22 .
From the same viewpoint as above, it is preferable that the distance C1 between the cover sheet 40 and the inner edge 22b of the second seal portion 22 in the first direction X is equal to or greater than half the thickness of the package 1 containing the object 2. The thickness of the package 1 is measured at the intersection of an imaginary line that bisects the entire length in the first direction X and an imaginary line that bisects the entire width in the second direction Y, i.e., at the center of the package 1.

As shown in FIG. 4(a) and FIG. 4(b), the cover sheet 40 has an adhesive-coated portion 42 formed by applying adhesive to the inner surface, which is the surface facing the first surface portion F1, so that a part of the adhesive is a non-adhesive-coated portion 43. In the inner surface of the cover sheet 40 of this embodiment, the adhesive-coated portion 42 is a portion where the adhesive is applied in a substantially annular shape, and the non-adhesive-coated portion 43 in the substantially annular portion is a missing portion where no adhesive is applied. For example, the adhesive-coated portion 42 has a rectangular ring shape or a circular ring shape (C-shape) with a missing part. On the inner surface of the cover sheet 40, the adhesive-coated portion 42 is formed in a peripheral area surrounding a portion that becomes the storage space S when the cover sheet 40 is attached to the second surface portion F2. The missing portion in the peripheral area where no adhesive is applied is the non-adhesive-coated portion 43. In other words, the adhesive is not applied to the portion surrounded by the adhesive-coated portion 42. The storage space S will be described later.
Alternatively, after the adhesive is applied to the entire inner surface of the cover sheet 40 to form a coated surface, printing may be performed on the coated surface to form the adhesive-coated areas 42 and the adhesive-uncoated areas 43 .

The adhesive-coated portion 42 of this embodiment is provided along the periphery of the cover sheet 40 (see FIG. 4). In detail, of the periphery of the four sides of the inner surface of the cover sheet 40, which is a rectangle, the periphery along two short sides is the first short adhesive-coated portion 421 and the second short adhesive-coated portion 422, and the periphery along one long side connecting these short sides is the long adhesive-coated portion 423. The periphery along the other long side is the adhesive-non-coated portion 43. Therefore, the adhesive-coated portion 42 is substantially U-shaped (substantially C-shaped) composed of the two short adhesive-coated portions 421, 422 and the long adhesive-coated portion 423 connecting these ends. In this way, of the periphery of the cover sheet 40 consisting of four sides, the periphery along three sides is the adhesive-coated portion 42, and the periphery along one side is the adhesive-non-coated portion 43. The cover sheet 40 has no adhesive applied to its outer surface, which is the surface not facing the first surface portion F1.
From the viewpoint of adhesion, the width of the adhesive-coated portion 42 of the cover sheet 40 is preferably 3 mm or more, more preferably 5 mm or more, and more preferably 10 mm or more. From the viewpoint of peelability, the width of the adhesive-coated portion 42 is preferably 30 mm or less, more preferably 20 mm or less, and more preferably 15 mm or less. From the viewpoint of operability, it is preferable that the cover sheet 40 is attached to the first surface portion F1 so that the adhesive-coated portion 42 does not overlap with the lid sheet 4 before use of the package 1.

Each of the short-side adhesive-coated portions 421, 422 extends in the second direction Y (horizontal direction Y) with a constant width. Similarly, the long-side adhesive-coated portion 423 also extends in the first direction X (vertical direction X) with a constant width. The widths of the adhesive-coated portions 421, 422, 423 may be the same or different.
When a non-adhesive-coated portion 43 is formed along the peripheral edge of one side of the rectangular cover sheet 40, the side 40a along which the non-adhesive-coated portion 43 is formed is also referred to as the non-coated side 40a. In the cover sheet 40 shown in Fig. 4, one of the long sides 40a of two opposing sides along the longitudinal direction is the non-coated side 40a.

As shown in FIG. 4(a), one of the edges of each of the short adhesive-coated sections 421, 422 on the two opposing sides, which is located on the side of the non-adhesive-coated section 43, does not reach the long side 40a (non-coated side 40a) along the longitudinal direction of the cover sheet 40, but terminates before the long side 40a (non-coated side 40a) in the second direction Y. This has the advantage that when a user peels the cover sheet 40 off the first surface portion F1 of the package 1, the corners on both sides of the non-coated side 40a can be easily grasped with the fingers, making it easier to peel off the cover sheet 40.

4(b), on the outer surface of the cover sheet 40 of this embodiment, i.e., the surface not facing the first surface portion F1, a peel start indicator 41 indicating the peel start position of the cover sheet 40 is provided at a position corresponding to at least one of the two ends of the non-adhesive-coated portion 43 extending in the first direction X. This allows the user of the package 1 to easily recognize the position to start peeling the cover sheet 40, and to perform the peeling operation accurately and easily. From the viewpoint of achieving such an effect, it is sufficient that the peel start indicator 41 is provided at a position corresponding to one of the four sides on the outer surface opposite the inner surface of the cover sheet 40 on which the non-adhesive-coated portion 43 is formed.
The peel start indicator 41 in this embodiment is an isosceles triangle, and the apex of the triangle is located at a corner of the cover sheet 40. The apex of this isosceles triangle peel start indicator 41 indicates the peel start position or peel direction of the cover sheet 40. Examples of the peel start indicator 41 include painting in a color different from the background color of the cover sheet 40, displaying letters, symbols, and/or figures, etc.

The cover sheet 40 may be transparent or opaque. In either case, the outer surface of the cover sheet 40 may be provided with a display related to the object 2 to be stored in the storage section 5. For example, a highly eye-catching design such as a product name, logo, image character, and/or catchy copy that evokes the object 2 may be provided on the outer surface of the cover sheet 40. Since the cover sheet 40 is made of a single flat sheet material, the sheet is less likely to bend or wrinkle compared to when a display is provided directly on the first surface F1 of the packaging body 1. Therefore, providing a display on the outer surface of the cover sheet 40 has the advantage that the packaging body 1 has a good appearance. However, this does not prevent a display from being provided on the first surface F1 of the packaging body 1. Therefore, for example, a display that is the same as or different from the display provided on the cover sheet 40 may be provided on the first surface F1 of the packaging body 1.

Regardless of whether the cover sheet 40 is transparent or opaque, instead of or in addition to applying various designs to the cover sheet 40, the space defined by the cover sheet 40 and the first surface portion F1 may contain flyers, samples, novelty goods, or the like bearing promotional messages to enhance the commercial value of the package 1.

When the cover sheet 40 is attached to the first surface portion F1, it is preferable that the adhesive coating portion 42 on the cover sheet 40 does not overlap with the lid sheet 4 (see Figures 1 and 3). This effectively prevents the lid sheet 4 from unintentionally peeling off and exposing the object 2 to be contained through the opening 3 when the cover sheet 40 is peeled off from the first surface portion F1.

5 to 7 show examples of use of the packaging body 1 shown in FIG.
The cover sheet 40 is peeled off from the first surface F1 of the package 1 and attached to the second surface F2, so that a space S (see FIGS. 6 and 7) is defined between the cover sheet 40 and the second surface F2. The cover sheet 40 is capable of storing an article in the space S through the non-adhesive coated portion 43. This will be described with reference to FIGS. 5(a) to (c) and 6.

First, as shown in FIG. 5(a), peel off the cover sheet 40 from the first surface F1 of the package 1. At this time, the peeling operation can be easily performed by pinching the part of the cover sheet 40 where the peel start indicator 41 is located with two fingers and pulling up the cover sheet 40.

Next, as shown in FIG. 5(b), the package 1 is turned upside down so that the second surface F2 faces upward. In this state, the second surface F2 faces the inner surface of the cover sheet 40 (i.e., the surface on which the adhesive coating portion 42 is formed). Then, as shown in FIG. 5(c), the cover sheet 40 is attached to the second surface F2. When attaching the cover sheet 40, the attachment position of the cover sheet 40 is determined using the target mark 50 provided on the surface of the second surface F2 as a guide, as shown in FIG. 5(b). In other words, the target mark 50 is an indication of the appropriate attachment position of the cover sheet 40 on the second surface F2.

The target mark 50 is generally L-shaped as shown in FIG. 5(b), and is provided at a position that coincides with a pair of adjacent corners 47, 48 of the cover sheet 40 when the cover sheet 40 is attached in the appropriate position on the second surface portion F2. Specifically, the target marks 50 are provided in two locations: the corner 47 at the intersection of the first short-side adhesive coated portion 421 and the long-side adhesive coated portion 423 of the cover sheet 40, and the corner 48 at the intersection of the second short-side adhesive coated portion 422 and the long-side adhesive coated portion 423.

Using the two target marks 50, 50 shown in FIG. 5(b) as guides, the cover sheet 40 is attached to the second surface portion F2 as shown in FIG. 5(c). When attachment is complete, the positions of the two long sides 40a, 40b of the cover sheet 40 are approximately aligned with the positions of the two long sides F2a, F2b of the second surface portion F2 as shown in FIG. 5(c). Also, the positions of the two short sides 40c, 40c of the cover sheet 40 are approximately aligned with the positions of the inner edges 22b, 22b of the second seal portion 22 as shown in FIG. 5(c).

When the attachment operation of the cover sheet 40 to the second surface portion F2 is completed in this manner, a space S is defined by the cover sheet 40 and the second surface portion F2, as shown in Fig. 6. An article can be stored in this space S through the non-adhesive coated portion 43.
In this way, according to the package 1, the cover sheet 40 used for the purpose of ensuring the virginity of the lid sheet 4 is also used as a member for forming the storage space S for the item, so there is no need to prepare a separate member for forming the space S. From this point of view, the package 1 makes it possible to reduce the amount of resin used. In addition, since the used object 2 can be stored in the storage space S, it is highly convenient (see FIG. 7).
7 shows a state in which a used storage object 2 is stored in the storage space S. The item stored in the storage space S is not limited to the used storage object 2, and may be other garbage or the like.

Various markings can be provided on the surface of the second surface F2. For example, a package insert showing the efficacy or ingredients of the contained object 2 can be provided. It is technically possible to display the package insert on the first surface F1, but in that case the package insert would be covered by the cover sheet 40. Therefore, it is preferable to display the package insert on the second surface F2. The cover sheet 40 is attached to the second surface F2, but since this is when the package 1 is in use, it does not matter if the package insert is covered by the cover sheet 40 and cannot be seen. In fact, since package inserts are often displays that are inferior in design, it is advantageous in terms of enhancing the design of the entire package 1 to have the package insert covered by the cover sheet 40, which is a highly designed member.

The adhesive strength of the adhesive-coated portion 42 of the cover sheet 40 is preferably such that it can be easily peeled off from the first surface F1 by a person pulling it lightly, and that it will not peel off in its natural state (when no external force is applied) after being attached to the second surface F2. This can further improve the operability of the cover sheet 40.
The adhesive strength of the adhesive-coated portion 42 can be measured as the peel strength of the cover sheet 40. From the viewpoint of further improving operability, the peel strength of the cover sheet 40 is preferably within the following range.
From the viewpoint of preventing unintentional peeling at a storefront or the like, the peel strength of the cover sheet 40 from the first surface portion F1 is preferably 1 N or more and 100 N or less, more preferably 2 N or more and 90 N or less. From the viewpoint of facilitating peeling during use, the peel strength of the cover sheet 40 from the first surface portion F1 is preferably 0.1 N or more and 50 N or less, more preferably 0.5 N or more and 30 N or less.
From the viewpoint of making it easier to reattach the cover sheet 40 to the second surface F2, the cover sheet 40 has a peel strength from the second surface F2 of preferably 0.1 N to 70 N, more preferably 0.5 N to 50 N. From the viewpoint of improving the resistance to peeling when a used storage object 2 is stored in a state in which the cover sheet 40 is attached to the second surface F2, the cover sheet 40 has a peel strength from the second surface F2 of preferably 2 N to 200 N, more preferably 3 N to 150 N. The peel strength from the second surface F2 is the strength when the cover sheet 40 peeled from the first surface F1 is attached to the second surface F2 and then the cover sheet 40 is peeled from the second surface F2.
The peel strength is measured by the following method.

[Method of measuring peel strength]
A hole with a diameter of 6 mm is opened at any position in the adhesive non-coated portion 43 of the cover sheet 40 attached to the first surface F1 or the second surface F2. A hook-shaped jig is then hooked onto the hole, and a force gauge connected to the jig is used to measure the maximum strength when the cover sheet 40 is peeled off from the first surface F1 or the second surface F2, which is the peel strength. When the cover sheet 40 is attached to the first surface F1 from the beginning, the cover sheet 40 is attached to the second surface F2 and left to stand for one day in an environment at 20°C, and then the peel strength from the second surface F2 is measured by the above-mentioned method. When the cover sheet 40 is attached to the second surface F2 from the beginning, the cover sheet 40 is attached to the first surface F1 and left to stand for one day in an environment at 20°C, and then the peel strength from the first surface F1 is measured by the above-mentioned method.
If the inner surface of the cover sheet 40 has an easily peelable joint 73, as described below, a piece of paper or the like is attached to the easily peelable joint 73 to neutralize the adhesive force of the easily peelable joint 73, and then the above measurement is performed.

The peel strength can be adjusted by either the type of adhesive or the area or dimensions of the adhesive-coated portion 42 .
For example, the adhesive forming the adhesive-coated portion 42 is preferably an acrylic adhesive, a silicone adhesive, a urethane adhesive, a rubber adhesive, or the like.
From the viewpoint of making it easier to keep the peel strength within the aforementioned range, the area of the adhesive-coated portion 42 is preferably 3% to 50%, and more preferably 10% to 30%, of the area of the cover sheet 40. The area of the adhesive-coated portion 42 is the area of the portion on the inner surface of the cover sheet 40 where the adhesive is present, and does not include the area of the adhesive-uncoated portion 43.
The width of the adhesive-coated portion 42 may be within the range described above. Furthermore, the shape of the adhesive-coated portion 42 is preferably a U-shape, i.e., a C-shape, or a trapezoid having a missing portion (adhesive-uncoated portion 43) on the upper side, or the like.

As shown in Figure 6, the packaging body 1 is advantageously configured such that, when the cover sheet 40 is attached to the second surface F2, the attachment directionality of the cover sheet 40 is determined so that the non-adhesive coated portion 43 is positioned in the opposite direction to the collapse direction i of the first seal portion 21 (the left direction on the paper in Figure 6). By attaching the cover sheet 40 to the second surface F2 in such a directionality, the operation of storing the used storage object 2 in the space S is less likely to be hindered by the first seal portion 21, as shown in Figure 7.

As an example of a configuration applied to the package 1 to uniquely determine the attachment direction of the cover sheet 40 to be attached to the second surface F2, an indication portion (not shown) indicating the attachment direction may be applied to the second surface F2. In other words, it is advantageous to apply an indication to the second surface F2 or the cover sheet 40 indicating that the cover sheet 40 is attached to the second surface F2 so that the non-adhesive coated portion 43 is positioned in the opposite direction to the collapse direction of the first seal portion 21. More specifically, when a used storage object 2 is stored in the space S, the storage object 2 is prevented from getting stuck in the first seal portion 21, which is advantageous in terms of operability during storage.

The packaging body 1 and its components of the present invention are not limited to the embodiment shown in Figures 1 to 7. Another embodiment of the packaging body 1 and its components of the present invention will be described below. In the following, the other embodiment will be described mainly with respect to the components that differ from the embodiment shown in Figures 1 to 7, and similar components will be given the same reference numerals and will not be described. For components that are not specifically described, the description of the embodiment shown in Figures 1 to 7 will be applied as appropriate.

In the above-described embodiment, the cover sheet 40A has the short adhesive-coated portions 421, 422 extending in the second direction Y in the adhesive-coated portion 42 not reaching the non-coated side 40a, but is not limited to such a form. The cover sheet 40A shown in Figs. 8(a) and (b) has adhesive-coated portions 421, 422 on two opposing sides, and among the edges of these adhesive-coated portions 421, 422, the edge located on the non-adhesive-coated portion 43 side reaches the edge of the cover sheet (non-coated side 40a). In other words, the short adhesive-coated portions 421, 422 extend over the entire width of the cover sheet 40 in the second direction Y. This makes it possible to further suppress peeling of the cover sheet 40A on the second surface portion F2.

The cover sheet 40A of the present embodiment has an indication 44 on the inner surface thereof, which indicates information regarding how to use the cover sheet 40A. The indication 44 on the inner surface of the cover sheet 40A is hereinafter also referred to as the "inner surface indication 44." The information regarding how to use the cover sheet 40A contained in the inner surface indication 44 is information regarding a method of forming a space S defined by the cover sheet 40A and the second surface F2 by attaching the cover sheet 40A to the second surface F2, and is information indicating the method by using characters, figures, images, or the like.
In addition to the above information, the inner surface display 44 may include information about the package and the object 2. This information may be a two-dimensional bar code, a URL, or the like.
When displaying information such as the information on the usage method on the inner surface of the cover sheet 40A, the entire inner surface of the cover sheet 40A may be coated with adhesive to form a coated surface, and the display may be printed on the coated surface to form the non-adhesive coated portion 43 and the substantially U-shaped (substantially C-shaped) adhesive coated portion 42. Alternatively, a resin film layer may be attached on the coated surface to form the non-adhesive coated portion 43 and the substantially U-shaped (substantially C-shaped) adhesive coated portion 42, and the display may be printed on the surface of the film layer.

In addition, in the cover sheet 40A of this embodiment, the peel start indication 41 is provided at a position corresponding to the non-coated edge 40a where the non-adhesive coated portion 43 is formed among the four sides on the outer surface of the cover sheet 40, but the position of the peel start indication 41 among the positions corresponding to the non-coated edge 40a is different from the form shown in FIG. 4 [see FIG. 8(b)]. More specifically, the peel start indication 41 of this embodiment is not present at the corners located on both sides of the non-coated edge 40a, but is provided at a position adjacent to the adhesive coated portion 421, which is located inside the first direction X from one of the short adhesive coated portions 421 extending in the second direction Y. In this way, by positioning the peel start indication 41 inside the first direction X from the adhesive coated portion 421 extending in the second direction Y, it is possible to more reliably guide the peeling to start from the non-adhesive coated portion 43, and the peeling operation of the cover sheet 40A can be performed more easily.

9(a) to (d) show variations in the position of the peel start indication 41. In FIG.
9( a), the peel start indication 41 does not have to be adjacent in the first direction X to the adhesive-coated portions 421, 422 extending in the second direction Y. The peel start indication 41 shown in FIG. 9( a) is located at the center in the first direction X of the adhesive-free portion 43 extending in the first direction X.
The peel start indication 41 shown in Figures 8 and 9(a) is provided in a position that does not overlap with the adhesive coated portion 42, but as shown in Figures 9(b) to (d), the peel start indication 41 may overlap with the adhesive coated portion 42 partially or entirely.
The peel start indication 41 shown in Figure 9 (b) has an isosceles triangle with its apex facing inward in the second direction Y and overlapping with the inner edge of the short adhesive coated portion 421 in the first direction X, and the outer half of the triangle facing in the first direction X overlaps with the short adhesive coated portion 421.
The peel start indicator 41 shown in FIG. 9( c ) overlaps with the short-side adhesive-coated portion 421 with the apex of the isosceles triangle facing inward in the first direction X.
The peel start indicator 41 shown in FIG. 9( d ) overlaps with the short-side adhesive-coated portion 421 with one equal side and the apex of the isosceles triangle being located on the non-coated side 40 a.

10(a) and (b) has a closing means 70 that at least partially closes an opening formed between the non-adhesive-coated portion 43 and the first surface portion F1 of the cover sheet 40B. Such an opening is a gap between the cover sheet 40 and the first surface portion F1 in the non-adhesive-coated portion 43. Closing by the closing means 70 can ensure that the cover sheet 40B remains unpeeled or that the lid sheet 4 remains unopened.
The closing means 70 in this embodiment is a tack seal 71 having a perforation 72. The perforation 72 and the uncoated edge 40a of the tack seal 71 overlap, and the tack seal 71 is attached across the uncoated edge 40a to the cover sheet 40 and the first surface F1. When the cover sheet 40B is peeled off from the first surface F1 of the package 1b, the tack seal 71 is torn along the perforation 72 (see FIG. 10(b)). Whether or not the cover sheet 40B has been peeled off (virginity) can be indicated by the presence or absence of this tear.
The tack seal 71 may have a shape such as an ellipse that is long in the second direction Y. In this case, when the cover sheet 40B is attached to the second surface F2 to form a space S defined by the cover sheet 40B and the second surface F2, the tack seal 71 that is long in the second direction Y may be used to close an opening on the side of the non-adhesive-coated portion 43, which is the entrance to the space S.

Variations of the closure means 70 are shown in Figures 11(a)-(d) and 12.
11(a) to (d) is an easily peelable joint 73, which joins the cover sheet 40B and the first surface F1 at the non-adhesive-coated portion 43. The easily peelable joint 73 is a portion where the cover sheet 40B and the first surface F1 are joined, and the area where the adhesive is present is smaller than the adhesive-coated portion 42, so that the joining at the easily peelable joint 73 can be easily released. The easily peelable joint 73 may be formed by printing on the portion where the adhesive is coated, to provide portions covered with the adhesive and portions not covered with the adhesive.
11(a) to (c) are rectangular in plan view, and are formed partially in the non-adhesive-coated portion 43. In this case, the package may have a single easy peelable joint 73 (see FIGS. 11(a) and (c)), or may have a plurality of easy peelable joints 73 (see FIGS. 11(a) and (c)).
As shown in Figures 11(a) and (b), the easy peelable bonding portion 73 may be provided in a position in the non-adhesive-coated portion 43 that does not overlap with the peel start indicator 41. Alternatively, only the easy peelable bonding portion 73 may be provided in the non-adhesive-coated portion 43 (see Figures 11(c) and (d)). Alternatively, as shown in Figure 11(d), the easy peelable bonding portion 73 may extend continuously over the entire length of the non-adhesive-coated portion 43 in the first direction X.

The closing means 70 shown in FIG. 12 is a breakable joint 75 formed along the non-coated edge 40a of the cover sheet 40B. The breakable joint 75 is a long piece portion of the cover sheet 40B that extends outward in the second direction Y beyond the non-adhesive-coated portion 43, is continuous with the cover sheet 40B via a perforation, and extends in the first direction X. The breakable joint 75 is also bonded to the first surface portion F1 over its entire area. The cover sheet 40B shown in FIG. 12 has the breakable joint 75 and a peeling extension portion 431 that extends outward in the first direction X beyond the short-side adhesive-coated portion 421. The breakable joint 75 is also formed in the peeling extension portion 431 and is continuous over the entire length of the cover sheet 40B in the first direction X, including the peeling extension portion 431.
12, the non-coated edge 40a is formed by peeling the cover sheet 40B from the first surface F1 while tearing the cover sheet 40B along the perforation while gripping the peel-off extension 431. By this tearing, the cover sheet 40B is separated from the tear joint 75, while the tear joint 75 remains on the first surface F1.

In the embodiment shown in Figures 9 to 12, the opening formed between the non-adhesive coated portion 43 and the first surface portion F1 is at least partially closed by the closing means 70, but as shown in Figures 1 to 8, the package does not have to include the closing means 70.

In a manufacturing process described below, the cover sheet 40 is attached to the soft packaging material 10 via the adhesive-coated portion 42, and then the soft packaging material 10 is shaped into a cylinder to form the first sealed portion 21. Before the first sealed portion 21 is formed, the soft packaging material 10 to which the cover sheet 40 is attached may be transported by transport rolls or the like. During this transport, air may get between the cover sheet 40 and the soft packaging material 10 from the non-adhesive-coated portion 43, causing wrinkles in the cover sheet 40. In particular, when the soft packaging material 10 is introduced between a pair of transport rolls, the air getting in may easily cause wrinkles in the cover sheet 40.
From the viewpoint of suppressing the infiltration of air and further suppressing the occurrence of wrinkles, it is preferable that the cover sheet 40 has a structure shown in FIG.
The cover sheet 40C shown in FIG. 13(a) has an adhesive-coated portion 42 that is substantially U-shaped, and a non-adhesive-coated portion 43 is formed on the periphery along one of the short sides of the cover sheet 40C. The adhesive-coated portion 42 is formed by longitudinal adhesive-coated portions 423, 424 provided on the periphery along a pair of long sides of the cover sheet 40C, and a transverse adhesive-coated portion 422 provided on the periphery along the other short side. The non-adhesive-coated portion 43 faces the transverse adhesive-coated portion 422 in the first direction X. When the conveying direction of the soft packaging material 10 corresponds to the first direction X, the cover sheet 40C shown in FIG. 13(a) is less likely to let air in through the non-adhesive-coated portion 43, and wrinkles can be further suppressed.

The cover sheet 40C shown in Figs. 13(b) to (c) has an approximately U-shaped adhesive-coated portion 42 provided on the periphery along the three sides of the cover sheet 40C, and an adhesive-free portion 43 provided on the periphery along one long side of the cover sheet 40C. The adhesive-coated portion 42 is formed by a longitudinal adhesive-coated portion 423 provided on the periphery along one long side of the cover sheet 40C, and short adhesive-coated portions 421, 422 provided on the periphery along a pair of short sides. The cover sheet 40C shown in Figs. 13(b) to (d) has a circular easy-to-peel joint portion 73 spaced apart from one long side of the cover sheet 40C, making it more difficult for air to enter through the opening formed between the adhesive-free portion 43 and the first surface portion F1.

13B is located in the non-adhesive-coated portion 43. From the viewpoint of further suppressing air from entering through the non-adhesive-coated portion 43, it is preferable that the cover sheet 40C has the following configuration.
The distance L1 (see FIG. 13(b)) between the easy-peel bonding portion 73 and the non-coated edge 40a in the second direction Y is preferably 3% to 60%, and more preferably 8% to 30%, of the length L _Y (see FIG. 13(b)) in the second direction Y of the portion of the cover sheet 40C that forms the storage space S. The "portion of the cover sheet 40C that forms the storage space S" refers to the portion of the cover sheet 40C where no adhesive is applied, including the non-adhesive-coated portion 43.
The distance L1 (see FIG. 13(b)) is preferably 3 mm or more and 30 mm or less, and more preferably 10 mm or more and 20 mm or less.
The shortest distance L2 (see FIG. 13(b)) between the easily peelable joint 73 and the adhesive-coated portions 421, 422 in the first direction X is preferably 5% or more and less than 50%, and more preferably 20% or more and less than 50%, of the length _LX (see FIG. 13(b)) in the first direction X of the portion of the cover sheet 40C that forms the storage space S. The shortest distance L2 is the shortest distance between each of the pair of adhesive-coated portions 421, 422 and the easily peelable joint 73 in the first direction X.
The shortest distance L2 (see FIG. 13(b)) is preferably 5 mm or more and less than 50 mm, and more preferably 10 mm or more and less than 50 mm.

13C has an easily peelable bonding portion 73a located in the non-adhesive-coated portion 43, and also has an easily peelable bonding portion 73b (hereinafter also referred to as an "inner bonding portion 73b") located inward in the second direction Y from the easily peelable bonding portion 73a. Such a cover sheet 40C has two inner bonding portions 73b, 73b located approximately in the center in the second direction Y and spaced apart in the first direction X.
13D has a plurality of easily peelable bonding portions 73a and an inner bonding portion 73b. The cover sheet 40C has one inner bonding portion 73b located approximately at the center in the second direction Y and spaced apart in the first direction X.

In order to suppress the occurrence of wrinkles in the cover sheet 40C due to transport while further improving operability when peeling the cover sheet 40C from the first surface portion F1, it is preferable that the easily peelable joint 73 including the inner joint 73b has the following configuration.
The area of each easily peelable joint 73 is preferably 0.01% to 10%, and more preferably 0.1% to 5%, of the area of the portion forming the storage space S of the cover sheet 40C.
The area of each of the easy peelable joints 73 is preferably 5 mm ² or more and 100 mm ² or less, and more preferably 10 mm ² or more and 30 mm ² or less.
The area of the easily peelable joints 73 is preferably 1% to 50%, and more preferably 10% to 30%, of the area of the portion of the cover sheet 40C that forms the storage space S. As shown in Figures 13(c) and 13(d), when the cover sheet 40C has a plurality of easily peelable joints 73, the "area of the easily peelable joints 73" refers to the total area of the plurality of easily peelable joints 73.
The separation distance L3 in the second direction Y between the easily peelable joint 73a and the inner joint 73b (see Figure 13(c)) is preferably 5% or more and 50% or less, and more preferably 10% or more and 30% or less, of the length L _Y in the second direction Y of the portion of the cover sheet 40C that forms the storage space S (see Figure 13(c)).
The distance L3 is preferably 5 mm or more and 50 mm or less, and more preferably 10 mm or more and 30 mm or less.
In addition, from the viewpoint of further improving operability when peeling off the cover sheet 40C from the first surface portion F1, it is preferable that the easily peelable joint 73a and the inner joint 73b do not overlap in position in the first direction X (see Figures 13 (c) and (d)).

When the cover sheet 40C has short adhesive coated parts 421, 422 provided on the periphery along a pair of short sides, from the viewpoint of achieving both releasability from the first surface part F1 and attachability to the second surface part F2, it is preferable that one of the short adhesive coated parts of the cover sheet 40C does not reach the non-coated side 40a (see FIG. 14). That is, one of the short adhesive coated parts 422 terminates before the non-coated side 40a in the second direction Y, and the other short adhesive coated part 421 reaches the non-coated side 40a. In this case, the part 425 between the short adhesive coated part 422 that does not reach the non-coated side 40a on the outer surface of the cover sheet 40C and the non-coated side 40a can be the peel start part 425 of the cover sheet 40C. The cover sheet 40C of this embodiment may have a peel start indicator 41 on its outer surface at a position corresponding to the peel start portion 425 (not shown in FIG. 14).

In the package 1c shown in FIG. 15, the cover sheet 40D has an inner surface mark 44a on the inner surface for aligning the attachment position of the cover sheet 40D with the target mark 50. The cover sheet 40D has a longitudinal adhesive coated portion 423 that connects to a pair of transverse adhesive coated portions 421, 422, and an inner surface mark 44a is located at each of the two corners formed by the inner edge of the longitudinal adhesive coated portion 423 in the second direction Y and the inner edge of the transverse adhesive coated portions 421, 422 in the first direction X. The cover sheet 40D is attached to the appropriate position on the second surface F2 by arranging the inner surface mark 44 and the target mark 50 provided on the second surface F2 so as to overlap each other.

As shown in Figures 13 to 15, the cover sheets 40C and 40D may be rectangular with rounded corners. Also, as shown in Figures 8 to 12, the cover sheets 40A and 40B may be rectangular with right-angled corners.

16 has an opening 3a for removing the object 2 on the second surface F2 including the first seal portion 21. The first surface F1 of this embodiment does not have an opening for removing the object 2.
The opening 3a in this embodiment is a slit-shaped opening extending in the first direction X, and is provided with a chuck mechanism having interlocking protrusions and recesses. The chuck mechanism allows the opening 3a in this embodiment to be opened and closed freely. The opening 3a in this embodiment is formed outward in the second direction Y from the first seal portion 21, but the position of the opening 3a is not particularly limited.

The packaging body 1d of the present embodiment includes a cover sheet 40 attached so as to cover at least a part of the surface opposite to the surface F2 in which the opening 3a is formed. More specifically, the packaging body 1d of the present embodiment includes a cover sheet 40 attached to the first surface F1 opposite to the second surface F2 in which the opening 3a is formed (see FIG. 16 ).
In the packaging body 1d of this embodiment, the cover sheet 40 is attached to the first surface portion F1 before use. The cover sheet 40 may be attached to the first surface portion F1 in a detachable manner, or may be attached to the first surface portion F1 in a non-detachable manner. In either case, in the packaging body 1d of this embodiment, a space S is formed between the cover sheet 40 and the first surface portion F1, and an article can be stored through the non-adhesive coated portion 43, as in the above-mentioned embodiment. That is, in the packaging body 1d of this embodiment, the cover sheet 40 is not reattached.

The package in which the cover sheet 40 is attached to the surface opposite to the surface in which the opening for removing the contained object 2 is formed is not limited to the form shown in FIG. 16. For example, the surface in which the opening is formed is the first surface F1, and the surface to which the cover sheet 40 is attached is the second surface F2.

The package 1f shown in FIG. 17 is taller than the packages of the above-mentioned embodiments. That is, the height (length in the height direction) of the third surface F3 is higher than the packages of the above-mentioned embodiments. The package 1f shown in FIG. 17 is illustrated with the second surface F2 having the first seal portion 21 (not shown in FIG. 17) as the ground surface, and an opening 3 is formed in the first surface F1, and the opening 3 is closed by the lid sheet 4. The package 1f of this embodiment has a hexahedral shape, and the storage section 5 has a pair of third surfaces F3, F3 facing the second direction Y between the first surface F1 and the second surface F2, as well as a pair of fourth surfaces F4, F4 facing the first direction X. These third surface F3 and fourth surface F4 are side surfaces located between the first surface F1 and the second surface F2 in the package 1f. The fourth surface portion F4 is formed by folding end regions extending outward in the first direction X from each of the first surface F1 and the second surface F2 toward the inside side in the first direction X (the storage portion 5 side). More specifically, in the soft packaging material 10, the first extension portion 24 extending outward in the first direction X from the first surface portion F1 and the second extension portion 25 extending outward in the first direction X from the second surface portion F2 are joined in a palm-to-palm shape by the second seal portion 22 at their outer ends in the first direction X, and the fourth surface portion F4 is formed by folding the first extension portion 24 and the second extension portion 25 toward the second surface portion F2. The first extension portion 24 is folded toward the second surface portion F2 along the second direction Y at the edge connected to the first surface portion F1. As a result, the outer surface of the fourth surface F4 is formed by the first extension portion 24. The second extension portion 25 is folded along the second direction Y at an edge connected to the second surface portion F2, and is further folded along the second direction Y at a point 25a (hereinafter also referred to as the "outward folded portion 25a") that is outward in the first direction X from the folded point. The end of the second extension portion 25 that is outward in the first direction X from the outward folded portion 25a is folded toward the second surface portion F2, and the second extension portions 25 face each other. The opposing second extension portions 25 are joined to each other with an adhesive.

The package 1f shown in FIG. 17 includes a cover sheet 40 on one of the third surfaces F3. In this manner, the cover sheet 40 may be peelably attached so as to cover at least a portion of one of the third surfaces F3. The cover sheet 40 of this embodiment is disposed on the third surface F3 so that the non-adhesive coated portion 43 is on the first surface F1 side. As a result, with the second surface F2 being the ground surface, a storage space S is formed with the upper side (the first surface F1 side) open at the non-adhesive coated portion 43, so that the used storage object can be stored in the storage space S. Alternatively, the cover sheet 40 may be peeled off from the third surface F3 and then attached to either the second surface F2 or the fourth surface F4 for use.
17, the cover sheet 40 is removably attached to cover at least a portion of either the third surface F3, but instead, the cover sheet 40 may be removably attached to either the side surface of the third surface F3 or the fourth surface F4 so as to cover at least a portion of the surface. Also, multiple cover sheets 40 may be attached to one or more of the side surfaces F3, F4 of the storage section 5.
Furthermore, the packaging body 1f may include a plurality of cover sheets 40, each of which may be attached to a different surface among the first surface F1, the second surface F2, the third surface F3, and the fourth surface F4. For example, the packaging body 1f may include a cover sheet 40 on the second surface F2, and another cover sheet 40 on any one of the third surfaces F3.

The packaging body in the above-described embodiment has the first sealed portion 21 formed by joining a pair of side regions of a single sheet of soft packaging material 10 in a palm-to-palm shape, but is not limited to this form. For example, the first sealed portion 21 may be formed by overlapping the edges of a pair of side regions of a single sheet of soft packaging material 10 while shifting them in the second direction Y, and then joining the overlapped portions. In this case, the first sealed portion 21 forms one side edge of the packaging body 1 along the first direction X, and is integrated with the second surface portion F2.
The package may be one in which the edges of one sheet of soft packaging material 10 folded in half are sealed on three sides to form a first sealed portion 21 and a pair of second sealed portions 22. Alternatively, the package may be one in which two sheets of soft packaging material 10 are overlapped and their edges are sealed on all four sides to form a pair of first sealed portions 21 and a pair of second sealed portions 22. A package having the first sealed portion 21 and the second sealed portion 22 formed by sealing on three or four sides has three or four sides of the edge of the package sealed in a plan view. In this case, the first surface portion F1 and the second surface portion F2 each include the first sealed portion 21 and the second sealed portion 22, respectively.

Next, a preferred method for producing the package of the present invention will be described using a method for producing the package 1 shown in FIG. 1 as an example.
The manufacturing method of this embodiment includes a cutting step of forming an opening 3 in a sheet of soft packaging material 10, a lid attachment step of attaching a lid sheet 4 to the soft packaging material 10 so as to cover the opening 3, an attachment step of attaching a cover sheet 40 to the soft packaging material 10 after the lid attachment step, a tubular body formation step of joining the side regions of the soft packaging material 10 together in a folded shape to form a tubular shape after the attachment step, and an end joining step of joining end regions, which are both ends of the tubular body made of the soft packaging material 10 on which the first sealed portion 21 has been formed, to form a pair of second sealed portions 22.

In the manufacturing method of this embodiment, a pasting step is performed on the soft packaging material 10 after the cutting step and the lid pasting step, i.e., on the soft packaging material 10 in which the opening 3 is formed and the lid sheet 4 covering it is pasted. In the pasting step, a cover sheet 40 is pasted to a location corresponding to the first surface portion F1 of the soft packaging material 10. An adhesive-coated portion 42 and an adhesive-uncoated portion 43 are formed in the cover sheet 40 in advance, and the cover sheet 40 is pasted to the first surface portion F1 by adhesion of the adhesive-coated portion 42.
In the cylindrical body forming step, the contents 2 (laminate 2S) are placed on the soft packaging material 10 after the attachment step, and the side regions of the soft packaging material 10 are joined together in a palm-to-palm manner, thereby forming the first sealed portion 21. In the cylindrical body forming step of this embodiment, the joining is performed by heat sealing processing.
In the cylindrical body forming process, linear folds extending in the first direction X are formed in the cylindrical body at locations corresponding to the third surface portions F3, thereby giving the cylindrical body a gusset-like shape.

In the end joining step, the end regions of the cylindrical body are joined to close the openings of the end regions. In this embodiment, the end regions are joined by a heat sealing process. As a result, a pair of second seal portions 22 are formed, and the storage portion 5 containing the object 2 is formed.
Through the above steps, the package 1 shown in FIG. 1 is manufactured.

As described above, the present invention is not limited to the above-described embodiment and can be modified as appropriate. In addition, the above-described embodiments may be combined.
For example, in the above embodiment, the ends of the first and second short-side adhesive-coated portions 421, 422 provided on the cover sheet 40 were connected to the long-side adhesive-coated portion 423 to form a continuous, approximately C-shaped adhesive-coated portion 42. However, instead, to the extent that items stored in the space S do not fall out, the short-side adhesive-coated portions 421, 422 and the long-side adhesive-coated portion 423 may not be connected, and each of the adhesive-coated portions 421, 422, 423 may be individually independent.
In addition, the non-adhesive coated portion 43 on the cover sheet 40 is provided on the peripheral edge portion of one side of the cover sheet 40 along the first direction X, but it may also be provided on the peripheral edge portion of one side of the cover sheet 40 along the second direction Y.
In addition, the adhesive-coated portion 42 may be provided in a portion other than the peripheral portion of the cover sheet. For example, in a plan view of a rectangular cover sheet, the adhesive-coated portion 42 may be provided 10 mm or more inward from the peripheral edges of the four sides.

In the above embodiment, each of the adhesive-coated sections 421, 422, and 423 is formed by continuously applying adhesive. Alternatively, each of the adhesive-coated sections 421, 422, and 423 may be formed by intermittently applying adhesive to the extent that the items contained in the space S do not fall off. Examples of intermittent application include adhesive-coated sections 42 in which adhesive is applied in stripes, spirals, or dashed lines.

In the above embodiment, the target marks 50 are provided in two places on the second surface portion F2, but the number of target marks is not limited to this, and may be, for example, one place, or three or more places. Also, the shape of the target mark 50 is not limited to that shown in FIG.
The pair of second sealed portions 22, 22 may have the same or different lengths (vertical widths) in the first direction X. In the latter case, a hanging hole for hanging and displaying the package 1 may be formed in the second sealed portion 22 having the longer vertical width.

In the above embodiment, one cover sheet 40 is attached to the first surface F1, but instead, two or more cover sheets, which may be the same or different, may be attached. Examples of such a configuration include those shown in Figures 18(a) to 18(d).
18(a) to (d) includes two cover sheets 40. The non-adhesive coated portions 43 of the cover sheets 40 are formed on one of two sides along the first direction X of an attachment surface (not shown) of the storage section 5 to which the cover sheet 40 is attached. The attachment surface is the first surface portion F1 or the second surface portion F2.
In the package 1e shown in Fig. 18(a), two cover sheets 40 of the same shape and size are arranged in parallel along the first direction X. The outlines and application surfaces of these two parallel cover sheets 40 are approximately the same in area and shape. In the package 1e shown in Fig. 18(a), two spaces S are formed between the cover sheets 40 and the application surfaces.
A package 1e shown in FIGS. 18(b) to (d) has two cover sheets 40 arranged to overlap partially or entirely.
In the package 1e shown in Fig. 18(b), two cover sheets 40 of the same shape and size are arranged in a partially overlapping state in the first direction X. In the package 1e shown in Fig. 18(b), a space S is defined by one cover sheet 40 and the attachment surface, and a space S is defined by one cover sheet 40, the other cover sheet 40 and the attachment surface.
The package 1e shown in Fig. 18(c) has two cover sheets 40 of the same shape and size arranged in a generally overlapping state. In the package 1e shown in Fig. 18(c), a space S is formed between one cover sheet 40 and the attachment surface, and a space S is formed between the other cover sheet 40 and the one cover sheet 40. These spaces S are formed in two layers in the thickness direction of the package 1e.
A package 1e shown in Fig. 18(d) has two cover sheets 40 of different sizes, with the smaller cover sheet 40 overlapping the larger cover sheet 40. In the package 1e shown in Fig. 18(d), a space S is formed between the larger cover sheet 40 and the attachment surface, and a space S is formed between the smaller cover sheet 40 and the larger cover sheet 40. These spaces S are formed in two layers in the thickness direction of the package 1e.
In this manner, when two or more cover sheets are provided, the arrangement of the non-adhesive-coated portions 43 provided on each cover sheet may be different. For example, one cover sheet 40 may have a non-adhesive-coated portion 43 formed on the peripheral portion of one side of the peripheral portion that runs along the first direction X, and the other cover sheet 40 may have a non-adhesive-coated portion 43 formed on the peripheral portion of one side of the peripheral portion that runs along the second direction Y.
