Description

  The present invention relates to a folded open package for packaging contents such as liquid, paste, powder, granule, and tablet in foods, pharmaceuticals, cosmetics, and the like. More specifically, the present invention relates to a folded and opened package capable of accommodating a predetermined amount of contents.

To date, a large number of various packages have been proposed as a package capable of enclosing a predetermined amount of the contents as described above and taking out the desired amount as required. The package is also one of such packages.
In the package of Patent Document 1, a first sheet of semi-rigid plastic material and a second sheet of flexible plastic material are bonded together, and a single dose is placed in a sealed pocket formed between opposing surfaces of the sheets. The contents are enclosed. The cuts that are broken by the folding of the package are provided in a substantially straight line with respect to the first sheet perpendicular to the folding direction of the package. That is, by cutting and opening the cut of the first sheet by folding the package, the contents enclosed in the sealing pocket can be discharged from the cut of the first sheet.

  However, since the second sheet is formed of a flexible plastic material, when the contents are sealed in a sealed pocket formed between the sheets, the first sheet faces outward due to the pressure of the contents. Therefore, the volume in the sealed pocket is likely to change, and the volume of the content enclosed in the sealed pocket cannot be kept constant.

  If the thickness of the first sheet is increased, the deformation of the first sheet that occurs when the contents are filled can be reduced. However, increasing the thickness increases the material cost and also requires heat sealing. Since the heating time becomes longer, as the size of the package increases, the tendency for the heating time required for the deformation and heat sealing to occur in the first sheet becomes higher, and the manufacturing cost becomes higher.

Special table 2010-504888

  It is an object of the present invention to provide a folded and opened package capable of accommodating a predetermined amount of contents without breaking or damaging the opening function of the opening portion.

The present invention is a folded unwrapped package including an unsealed portion that is unsealed along with the folding operation of the package, and the package includes one member having the unfolded portion and one surface of the one member. The other member pasted together and an accommodating portion for accommodating the contents formed between the opposing surfaces of the members, wherein the one member encloses the opening portion set in the one member A deformation auxiliary ruled line that is attached to a region and a surface opposite to the opposing surface of the one member in the one member, and assists deformation of the one member in a direction opposite to the overlapping direction in which the members are overlapped with each other. The one member is formed into a substantially convex shape in cross section that protrudes in a direction opposite to the overlapping direction of the members by the deformation auxiliary ruled line, and the deformation auxiliary ruled line is set to the one member Around the unsealed area Characterized in that it is a attached to the surrounding auxiliary border is constituted by folding open packaging body so as to surround the opening region against.

The content can be configured in a liquid form, a paste form, a powder form, a granular form, a tablet form, or the like.
On the other hand, for example, amorphous polyethylene terephthalate (A-PET), polypropylene (PP), biaxially stretched polyester (OPET), biaxially stretched polypropylene (OPP), biodegradable plastic (PLA), polycarbonate (PC ), Polyethylene (PE), polystyrene (PS), cellulose propionate (CP), polyvinyl alcohol (PVA) cardboard, a single sheet material such as a metal sheet, a sheet formed of a composite material, or a film.

Specifically, one member can be constituted by a sheet or the like formed to have a thickness that can be folded in a folded state or a hardness, for example. Moreover, the other member can be comprised by the film etc. which have a softness | flexibility, for example.
The material and thickness of the member can be changed according to, for example, the type of contents or the shape of the housing portion.

  The unsealed portion covers, for example, an unpenetrated cut that is broken and opened by bending formed in the member, or a penetrated cut that penetrates in the thickness direction formed in the member, and is broken and opened by bending the member. It can be constituted by a break opening structure provided with a sealing material, a peeling opening structure in which a peelable part between members is peeled off by bending, and the penetrated cuts formed in the member are communicated and opened. .

  For example, JP-A 2003-266532, JP-A 2003-292020, JP-A 2004-1858, JP-A 2004-83129, JP-A 2004-315073, etc. The ruled line disclosed in (1) can be used.

According to this invention, a predetermined amount of contents can be accommodated without breaking or damaging the opening function of the opening portion.
Specifically, when the auxiliary deformation ruled line is attached to one member using, for example, a ruled blade, a portion of the ruled blade is pressed in the thickness direction to be deformed, and the shape corresponding to the blade is deformed. An auxiliary ruled line is attached. At that time, the part where the blade with ruled line is pressed is spread in the direction corresponding to the thickness of the blade with ruled line depending on the shape and angle of the blade edge, but on the other hand, the part on the side opposite to the part where the blade with ruled line is pressed The part cannot be expanded.

  Therefore, when the pressing of the blade with ruled line against one member is released and the blade with ruled line is separated from one member, the part where the deformation auxiliary ruled line in one member is attached is opposite to the overlapping direction of the members. Therefore, one member can be formed in a substantially convex shape in cross section that protrudes toward the outer side opposite to the overlapping direction of the members.

Thereby, it can prevent that one member is bent and deform | transformed into a distorted shape toward the direction opposite to the overlapping direction of members by the pressure of the content accommodated in the accommodating part.
As a result, it is possible to secure a volume necessary for accommodating a predetermined amount of contents, and it is possible to accommodate a predetermined amount of contents with less variation in the volume of the accommodating portion for accommodating the contents.

  In addition, it is not necessary to increase the thickness of the members in order to reduce the deformation, and when the members are thermally welded together, the heating time required for the welding can be shortened, so the material cost and the manufacturing cost can be reduced. .

Furthermore, the volume of the accommodating portion that accommodates the contents can be increased without deforming the portion where the opening portion in the opening region of one member is provided.
Specifically, the surrounding auxiliary ruled line is attached around the opening area of one member, and the surrounding of the opening area of the member is deformed in the direction opposite to the overlapping direction of the members. The volume of the accommodating portion can be increased while the portion provided with the opening portion in the enclosed opening region is maintained in a substantially flat state.

Thereby, it is hard to produce a deformation | transformation in the part which provided the opening part in the opening area | region enclosed by the surrounding auxiliary ruled line in one member, and it can prevent that the opening function of an opening part is damaged or damaged.
As a result, a predetermined amount of contents can be reliably stored and the opening function of the opening portion can be reliably maintained.

The present invention also relates to a folded-open packaging body having an opening portion that is opened by folding the packaging body, wherein the packaging body is attached to one member having the opening portion and one surface of the one member. An unsealed region surrounding the unsealed portion set in the one member, the other member being combined and an accommodating portion for accommodating the contents formed between the opposing surfaces of the members; And a deformation auxiliary ruled line attached to a surface opposite to the opposing surface of the one member in the one member, and assisting deformation of the one member in a direction opposite to the overlapping direction in which the members are overlapped with each other. The one member is formed in a substantially convex cross section projecting in a direction opposite to the overlapping direction of the members by the deformation auxiliary ruled line, and the deformation auxiliary ruled line is formed at an edge of the one member Between the opening area and Setting the linear, or can be composed of curved linear auxiliary border.
According to this invention, the volume of the accommodating part that accommodates the contents can be further increased without deforming the part of the one member provided with the opening part in the opening region.

  Specifically, a linear or curved linear auxiliary ruled line is attached between the edge of one member and the opening area provided on the member, and the edge and opening area of the member are Since the portion corresponding to the intermediate portion is deformed in the direction opposite to the overlapping direction of the members, the volume of the accommodating portion can be increased as compared with the case where the periphery of the opening region of one member is deformed.

Thereby, a part which provided the opening part in the opening area | region enclosed by the linear auxiliary ruled line in one member becomes harder to produce a deformation | transformation, and it can prevent that the opening function of an opening part is damaged or damaged.
As a result, a predetermined amount of contents can be more reliably accommodated, and the opening function of the opening portion can be more reliably maintained.

The present invention also relates to a folded-open packaging body having an opening portion that is opened by folding the packaging body, wherein the packaging body is attached to one member having the opening portion and one surface of the one member. An unsealed region surrounding the unsealed portion set in the one member, the other member being combined and an accommodating portion for accommodating the contents formed between the opposing surfaces of the members; And a deformation auxiliary ruled line attached to a surface opposite to the opposing surface of the one member in the one member, and assisting deformation of the one member in a direction opposite to the overlapping direction in which the members are overlapped with each other. The one member is formed in a substantially convex cross section projecting in a direction opposite to the overlapping direction of the members by the deformation auxiliary ruled line, and the deformation auxiliary ruled line is set to the one member Around the opening area On the other hand, it is composed of a surrounding auxiliary ruled line provided so as to surround the opening area, and a linear or curved linear auxiliary ruled line provided between the edge of the one member and the surrounding auxiliary ruled line. be able to.

According to the present invention, it is possible to more surely secure a volume necessary to accommodate a predetermined amount of contents.
Specifically, the surrounding auxiliary ruled line is attached so as to surround the periphery of the opening region of one member, and the portion corresponding to the surrounding auxiliary ruled line in the member is directed in the direction opposite to the overlapping direction of the members. Deform. Also, a linear or curved linear auxiliary ruled line is provided between the edge of one member and the surrounding auxiliary ruled line, and a corresponding part between the edge of the member and the enclosed auxiliary ruled line is provided. The member is deformed in the direction opposite to the overlapping direction of the members.

  That is, the portion corresponding to the unsealed area of one member and the portion corresponding to the edge of the member and the surrounding auxiliary ruled line are overlapped with each other by the synergistic action of the surrounding auxiliary ruled line and the linear auxiliary ruled line. It can be deformed in the opposite direction.

Accordingly, one member can be more reliably deformed in the direction opposite to the overlapping direction of the members than when any one of the above-described surrounding auxiliary ruled line and linear auxiliary ruled line is attached. For this reason, the volume of the accommodating portion can be increased more reliably.
As a result, a predetermined amount of contents can be more reliably accommodated, and the opening function of the opening portion can be more reliably prevented from being broken or damaged.

  Further, as an aspect of the present invention, a portion corresponding to the edge of the one member and the opening region or the surrounding auxiliary ruled line is directed to the outside opposite to the overlapping direction in which the members are overlapped. The protruding cross section can be formed in a substantially arc shape.

According to this invention, the volume of the storage part that stores the contents can be further increased.
Specifically, the portion between the edge of one member and the surrounding auxiliary ruled line is deformed into a substantially arc-shaped cross section that protrudes toward the outside opposite to the overlapping direction of the members, thereby opening the one member. It is possible to further increase the volume of the accommodating portion, rather than deforming the periphery of the region, or deforming a corresponding portion between the edge of one member and the opening region or the surrounding auxiliary ruled line.
As a result, it is possible to further increase the amount of contents stored in the storage unit.

  In addition, as an aspect of the present invention, a linear or curved folding ruled line that assists the folding of the sheet member is provided between both side edges of the one member and both side edges of the opening region, A portion extending from both side edge portions of the one member to the both side edge portions of the unsealed region in the bent ruled line is defined with respect to the reference line, with a line perpendicular to the central portion in the longitudinal direction of the unsealed region as a reference line It can be attached by being displaced to an angle of.

According to this invention, it is possible to prevent the unsealed portion from being broken at once when the folded unwrapped package is folded.
Specifically, for example, when an opening portion (for example, a notch) that is broken by folding the package body is linearly provided in a direction orthogonal to the folding direction of the package body, the linear opening portion and the package body Since the portion that becomes the peak side when the bag is folded is substantially linear, the opening is broken even if the package is slightly deformed in the folding direction due to external force applied during transportation or transportation. It is easy for the contents enclosed in the package to leak from the broken opening.

  On the other hand, the folded and opened package of the present invention has a portion extending from both side edges of one member of the folded ruled line to both side edges of the opening area, and a line perpendicular to the center in the longitudinal direction in the opening area. As the reference line, the reference line is displaced by a predetermined angle (specifically, an angle included in a range of about 0.5 degrees to about 5 degrees).

  As a result, when the folded and opened package is folded in a folded state, the central portion of the unsealed portion provided on one member is first broken and continuously from the previously opened central portion toward both ends. Is broken. Since the opened portion of the opening portion is small at the initial opening of the opening portion, the amount of the content extruded from the opening portion can be limited.

As a result, the contents can be prevented from being pushed all at once when the package is folded to open the opening portion provided on one member.
Moreover, since the opened portion of the opening portion gradually increases with the bending operation of one member, the amount of the content pushed out from the opening portion can be gradually increased.

  Furthermore, since the folding ruled line attached to the sheet member intersects the portion that becomes the mountain side when the sheet member is folded, the linear opening portion and the packaging body are folded as described above. Compared with the portion that becomes the mountain side substantially linearly, the resistance at the time of breaking the unsealed portion is large, for example, even if the sheet member is slightly deformed in the bending direction during transportation or transportation, the unsealed portion is broken It is hard to be done and it can prevent that the contents accommodated in the accommodating part leak.

  Further, as an aspect of the present invention, a sealing material that is broken when the one member is bent to a predetermined bending angle or less so as to cover the opening portion with respect to a surface that becomes a mountain side when the member is bent. Can be coated.

  The said sealing material can be comprised with thin foil bodies, such as aluminum foil, stainless steel foil, copper foil, iron foil, a resin film, for example. As an example of the foil body, when an aluminum foil having a thickness of 5 μm to 35 μm is used as a sealing material, it is possible to obtain a rupture-open packaging body having good moisture permeability, gas permeability, and rupture-openability. Here, the gas permeability refers to a gas barrier property that suppresses permeation of oxygen, moisture, corrosive gas, and the like.

  Other materials with good moisture permeability and gas permeability that can replace the above-mentioned aluminum foil, such as films made of polyvinylidene chloride, composite materials combined with other synthetic resins, films with good gas permeability deposited on aluminum, etc. You may comprise with the material according to the characteristic and physical property of a thing, and the thing of a material with weak tearing strength is desirable.

  Specifically, the folded and opened packaging body is folded in a folded state, and the sealing material covered so as to cover the unsealed portion with respect to the surface that becomes the mountain side when folded in the sheet member is extended in the middle of the folding of the sheet member. And break.

  As a result, it is possible to easily and easily break the sealing material covered so as to cover the unsealed portion of the sheet member by simply folding the folded unsealed package in a folded state, and the contents accommodated in the accommodating portion Can be smoothly taken out from the opening part opened by breaking the sealing material.

  Moreover, until the sealing material is broken and opened, the opening portion is not opened, and the contents stored in the storage portion can be prevented from leaking to the outside. For example, dust, insects, etc. It is possible to prevent the foreign matter from entering the housing portion from the opening portion.

  According to the present invention, it is possible to provide a folded and opened package capable of accommodating a predetermined amount of contents without breaking or damaging the opening function of the opening portion.

An embodiment of the present invention will be described in detail with reference to the drawings.
Example 1
FIG. 1 is an explanatory view of a folded unwrapped package 10 of Example 1. Specifically, FIG. 1A is a perspective view of the folded unwrapped package 10 viewed from the sheet member 20 side, and FIG. It is the top view which looked at the opening packaging body 10 from the sheet | seat member 20 side.

  FIG. 2 is an explanatory view of the structure of the folded and opened packaging body 10. Specifically, FIG. 2 (a) is a sectional view in which the folded and opened packaging body 10 is divided at the central portion in the short direction S, and an enlarged sectional view of the a portion. FIG.2 (b) is an expanded sectional view of the right side rather than the center part of the longitudinal direction L in the bending opening packaging body 10 shown to (a).

  In addition, the longitudinal direction L described later is a direction that coincides with the longitudinal direction L of the folded open package 10 having a substantially rectangular shape in plan view, and the short side direction S is a direction that intersects the longitudinal direction L in the planar direction. Yes (see FIG. 1).

  The folded open packaging body 10 of Example 1 is a substantially rectangular packaging body in a plan view in which the amount of contents C required for one use is enclosed, and is a wall thickness that can be folded in a folded state by a human finger. The sheet member 20 having flexibility formed in hardness (rigidity), the film member 30 having flexibility bonded to one surface of the sheet member 20, and the opposing surfaces of the members 20 and 30 are formed. And a storage unit 40 that stores a predetermined amount of contents C (see FIGS. 1 and 2).

  The sheet member 20 includes a sheet base portion 20a made of amorphous polyethylene terephthalate and a polyethylene sealing material 20b, and the sealing material 20b is bonded to the front and back surfaces of the sheet base portion 20a so as to cover both the front and back surfaces. It is formed in a substantially rectangular shape in plan view (see the enlarged view of the part a in FIG. 2A).

  The sheet base portion 20a is formed to have a thickness included in the range of 0.1 mm to 1.0 mm, desirably a thickness included in the range of 0.2 mm to 0.5 mm. The sealing material 20b is formed to have a thickness included in a range of 0.01 mm to 0.5 mm, desirably a thickness included in a range of 0.03 mm to 0.3 mm.

  When accommodating the contents C that require gas barrier properties and moisture proof properties, for example, a vapor deposition process, a coating process, or a combination of the processes, a sealing layer (not shown) is provided between the sheet base 20a and the sealing material 20b. To form.

  The film member 30 is formed of a synthetic resin film (for example, trade name Diamilon F manufactured by Mitsubishi Plastics, Inc.) formed to a thickness of 100 μm, and the entire surface (member 20) of the sheet member 20 having a substantially rectangular shape in plan view. , 30 is formed in a size and shape that covers the entire surface opposite to the opposing surface (see FIGS. 2A and 2B).

  When the sheet member 20 and the film member 30 are overlapped on one side of the sheet member 20, the opposing peripheral portions overlapped in the overlapping direction T between the members 20 and 30 are integrally joined ( Specifically, welding and adhesion).

  The accommodating part 40 is formed between the opposing surfaces inside the peripheral part where the members 20 and 30 are joined together. The container 40 is filled with an amount of content C necessary for one use from an opening formed at one side edge of the members 20 and 30 before joining the peripheral edge ( (Refer FIG. 2 (a) (b)).

  An opening region 21 </ b> A that is substantially rectangular in a plan view in the longitudinal direction is set in the longitudinal direction L of the sheet member 20 in the center portion on the surface side opposite to the opposing surface of the members 20 and 30 in the sheet member 20 described above. In the opening region 21A, an opening portion 22 is formed that is broken and opened when the sheet member 20 is folded in a folded state (see FIGS. 1A and 1B).

  The unsealing part 22 is configured by an unpenetrated cut 231 that is broken when the sheet member 20 is bent to a predetermined bending angle θ2 or less. The notch 231 is substantially arcuate in a plan view with respect to the central portion on the surface side in the unsealed region 21A of the sheet member 20 using a notched blade (not shown) formed in a size, shape, and length corresponding to the notch 231. (See FIGS. 2A and 3A).

  The cuts 231 of the first embodiment are formed symmetrically with a vertical line orthogonal to the central portion in the short direction S of the sheet member 20 as a virtual reference line (not shown), and the short side of the opening region 21A set in the sheet member 20 The length is formed from the center portion in the direction S to both side edge portions on the inner side from the peripheral edge portion of the sheet member 20 in which the members 20 and 30 are joined to each other (see FIGS. 1A and 1B).

  The total length from the center in the short direction S to both ends of the cut 231 is curved in an arc shape toward one end in the longitudinal direction L of the sheet member 20 with the center in the short direction S of the cut 231 as a reference. It is formed in a substantially arc shape in plan view (see FIGS. 1A and 1B).

  The cross-sectional shape of the cut 231 viewed from the length direction is formed in the same shape as a ruled line having a substantially V-shaped cross-section or a substantially U-shaped cross-section disclosed in the existing publication. The bottom of the notch 231 is formed to have a thickness that is broken when the sheet member 20 is bent to a predetermined folding angle θ2 or less (FIG. 3 (a) is an enlarged sectional view of FIG. 2 (a)). reference).

  The portion extending from the center in the short direction S to both ends in the cut 231 is predetermined with respect to the reference line with a line orthogonal to the center in the longitudinal direction L of the opening region 21A set in the sheet member 20 as a reference line. The angle θ1 (specifically, an angle included in a range of about 0.5 degrees to about 5 degrees) is displaced (specifically curved or inclined) (see FIG. 1B).

  The portions from the both side edges of the sheet member 20 to the both side edges of the opening area 21A in the cut 231 serve as folding ruled lines that assist the folding of the sheet member 20. When the sheet member 20 is folded in a folded state, the notch 231 is first broken from the center portion in the short direction S of the notch 231 along with the folding operation of the sheet member 20, and the center portion that has been broken first. Is continuously broken toward both end portions (see FIGS. 3A and 3B).

  Further, a deformation auxiliary ruled line 24A for assisting the deformation of the sheet member 20 is attached around the opening region 21A of the sheet member 20 in a direction opposite to the overlapping direction T in which the members 20 and 30 are overlapped. (See FIGS. 1A and 1B).

The deformation auxiliary ruled line 24A is composed of a surrounding auxiliary ruled line 25 having a substantially rectangular shape in plan view and linear auxiliary ruled lines 26 and 27 having a substantially straight line shape in plan view.
The surrounding auxiliary ruled lines 25 are slightly larger than the opened area 21A of the sheet member 20 than the opened areas 21A and 252 longer than the four sides of the opened area 21A set in the sheet member 20 and are surrounded by the opening area 21A including the opened portion 22. Are attached so as to surround the opening region 21A (see FIGS. 1A and 1B).

  The linear auxiliary ruled lines 26 include four auxiliary ruled lines 261 formed to have a length corresponding to the distance between the four corners of the sheet member 20 and the four corners of the surrounding auxiliary ruled line 25. Are attached to the corner corners of the surrounding auxiliary ruled lines 25 (see FIGS. 1A and 1B).

  The linear auxiliary ruled lines 27 are provided with auxiliary ruled lines 271 and 272 formed to a length corresponding to the four sides of the sheet member 20 at a portion inside the peripheral portion where the members 20 and 30 of the sheet member 20 are joined to each other. (See FIGS. 1A and 1B).

The cross-sectional shape of the auxiliary ruled lines 25, 26, 27 as viewed from the length direction is formed in the same shape as the ruled lines having a substantially V-shaped cross section or a substantially U-shaped cross section disclosed in the existing publications.
The auxiliary ruled lines 25 to 27 are composed of a pair of side portions that are inclined at a predetermined angle and face each other. The inner angle formed by the side surfaces is set to an angle included in the range of about 20 degrees to about 120 degrees (see FIG. 2B).

  That is, if the angle formed between the side portions of the auxiliary ruled lines 25 to 27 is increased in correspondence with the blade edge angle of the blade with ruled lines (not shown) used when the auxiliary ruled lines 25 to 27 are provided, the auxiliary ruled lines in the sheet member 20 are increased. Since the portion provided with 25 to 27 is further expanded in a direction corresponding to the thickness of the ruled blade, it can be more easily deformed.

  The cross-sectional shape of the auxiliary ruled line 27 as viewed from the length direction is such that one of the pair of side surfaces inclined at a predetermined angle and facing each other is inclined at a predetermined angle toward the side corresponding to the accommodating portion 40. The other side surface portion is formed at an angle that stands vertically (see FIG. 2B).

  For the auxiliary ruled lines 25, 26, 27, a surrounding auxiliary ruled line-equipped blade (not shown) formed in a size, shape, and length corresponding to the auxiliary ruled lines 25, 26, 27, and a linear auxiliary ruled line-equipped blade are used. Are attached to each.

  The portion where the ruled blade is pressed in the sheet member 20 described above is expanded in the direction corresponding to the thickness of the ruled blade according to the shape and angle of the blade edge, for example, but on the contrary, the portion where the ruled blade is pressed The part on the opposite side cannot be expanded.

  In other words, by releasing the pressing of the blade with ruled line against the sheet member 20 and separating the blade with ruled line from the sheet member 20, a portion provided with the surrounding auxiliary ruled line 25 and the linear auxiliary ruled line 26 on the sheet member 20 is provided. The members 20 and 30 are deformed in the direction opposite to the overlapping direction T between the members 20 and 30.

  Further, the sheet member 20 is placed on the outer side opposite to the overlapping direction T between the members 20 and 30 while the portion in the opening region 21A surrounded by the surrounding auxiliary ruled line 25F in the sheet member 20 is maintained in a substantially flat state. It is deformed into a substantially convex shape with a cross section projecting toward it (see FIGS. 2A and 2B).

This prevents the sheet member 20 from being bent and deformed into a distorted shape in the direction opposite to the overlapping direction T between the members 20 and 30 due to the pressure of the contents C accommodated in the accommodating portion 40. And a volume necessary to accommodate a predetermined amount of contents C can be secured.
As a result, the volume of the storage unit 40 that stores the contents C is unlikely to fluctuate, and a predetermined amount of the contents C can be reliably stored.

A method for taking out the contents C from the folded and opened package 10 according to the first embodiment configured as described above will be described.
3A and 3B are explanatory views when the folded and opened package 10 is opened. Specifically, FIG. 3A is a side view of the folded opened package 10 and FIG. 3B is a folded and opened package. It is a side view of the state which folded the body 10 in half.

  FIG. 4 is an explanatory diagram when the contents C is taken out from the folded and opened packaging body 10, and more specifically, the uncut through notch 231 formed in the opening portion 22 in the opening area 21A of the sheet member 20 is broken to show the contents. It is a partial expanded sectional view at the time of taking out C.

  The folded opening package 10 of Example 1 was formed in the opening portion 22 in the opening region 21 </ b> A in the sheet member 20 by holding the opening portion 22 of the sheet member 20 so as to face downward and bending it in a folded state. The cut 231 can be broken and opened (see FIGS. 3A and 3B).

  That is, both end portions in the longitudinal direction L of the folded and opened packaging body 10 with respect to the folding direction G so that the film member 30 side in the folded and opened packaging body 10 is inside and the sheet member 20 side is outside. And bend so that they overlap each other (see FIGS. 3A and 3B).

  When the folded open package 10 is started to be folded in the folding direction G, the notch 231 formed in the unsealed portion 22 in the unsealed region 21A of the sheet member 20 is first broken from the central portion in the short direction S, It is ruptured continuously from the center portion that was previously broken toward both ends (see FIG. 4).

For this reason, when the folding opening package 10 starts to be folded, the cut portion of the cut 231 is small, and the amount of the content C pushed out from the cut 231 can be limited.
As a result, it is possible to prevent the cut 231 of the opening portion 22 from being broken at once when the folded opened package 10 is folded.

In addition, since the portion of the cut 231 to be broken gradually increases with the folding operation of the sheet member 20, the amount of the content C pushed out from the accommodating portion 40 can be gradually increased.
Thereby, it can prevent that the content C accommodated in the accommodating part 40 is extruded at a stretch.

  Further, the portions from the both side edges of the sheet member 20 to the both side edges of the opening area 21A in the cut 231 serve as folding ruled lines that assist the folding of the sheet member 20 in the same manner as the folding ruled lines 202 of the sixth embodiment. .

  That is, since the portion corresponding to the folding ruled line 202 of Example 6 in the cut 231 intersects the portion that becomes the mountain side when the sheet member 20 is folded, for example, the straight cut and the packaging body The bending resistance applied when the cut 231 is broken is larger than the portion that becomes the peak side when bent is substantially linear.

  For this reason, for example, even if the sheet member 20 is slightly deformed in the bending direction G during transportation or transportation, the notch 231 is not easily broken, and the contents C accommodated in the accommodating portion 40 can be reliably prevented from leaking. it can.

  Furthermore, in order to prevent the cuts 231 from being broken all at once, it is not necessary to increase the thickness of the sheet member 20, and the amount of the material constituting the sheet member 20 can be reduced. The cost required for manufacturing 10 can be reduced.

  Furthermore, since the accommodating portion 40 that accommodates the contents C is formed by deforming the sheet member 20 into a predetermined shape, the deformation that occurs in the sheet member 20 or the film member 30 can be reduced, and as a packaging body The design property of can be improved.

  Furthermore, since a predetermined amount of the content C is accommodated in the accommodating portion 40 formed by deforming the sheet member 20, the restoring force of the sheet member 20 itself is not easily applied to the content C, for example, between the sheet and the film. Rather than press-fitting the contents C into the container, the pressure generated in the accommodating portion 40 can be reduced.

  Thereby, while being able to reduce the deformation | transformation which arises in the sheet | seat member 20 and the film member 30, it can prevent that the seal part of the peripheral part which joined members 20 and 30 is damaged or damaged.

  Furthermore, since it is possible to prevent the surface of the film member 30 from being deformed so as to make it difficult to read the display contents (characters, designs, etc.) relating to the contents C printed on the surface, the film member The display content printed on the surface 30 can be easily read, and the design of the film member 30 can be improved.

Furthermore, since the accommodating part 40 is formed by deforming the sheet member 20, it is possible to prevent deformation such as warpage from occurring in the folded and opened package 10 itself, and to increase the structural strength.
Thereby, the opening structure of the folded open package 10 can be applied to a large package having a large area, and the sales channel for selling the folded open package 10 can be further expanded.

  Furthermore, in the case of a general package, printing or processing is performed on a sheet that is not easily deformed, but the folded and opened package 10 of Example 1 may be designed with the film member 30 as a table, It can be set as the package excellent in design property and design property.

  Furthermore, since the film member 30 is thinner than the sheet member 20 and can be printed and processed easily and inexpensively, for example, the manufacturing cost can be reduced compared to printing on the sheet member 20.

  Hereinafter, other examples of the above-described folded opened package 10 will be described. In this description, parts that are the same as or equivalent to those in the above configuration are denoted by the same reference numerals, and detailed description thereof is omitted.

(Example 2)
In the first embodiment described above, an example in which the surrounding auxiliary ruled line 25 and the linear auxiliary ruled line 26 are connected has been described. However, as shown in FIG. 5, the surrounding auxiliary ruled line 25 and the linear auxiliary ruled line 26 in the deformation auxiliary ruled line 24A. The folding unwrapped packaging body 10 of Example 2 in which is separated and attached to individual ruled lines will be described.

  FIG. 5 is an explanatory diagram of the folded and opened package 10 of the second embodiment. Specifically, FIG. 5A is a perspective view of the folded and opened package 10 viewed from the sheet member 20 side, and FIG. 5B is a folded view. It is the top view which looked at the opening packaging body 10 from the sheet | seat member 20 side.

In the folded and opened package 10 of the second embodiment, the surrounding auxiliary ruled line 25 in the deformation auxiliary ruled line 24A is separated into four auxiliary ruled lines 251 and 252 and individually attached, and the linear auxiliary ruled line 26 is provided with four auxiliary ruled lines. Separated into H.261 and attached individually.
The four corners of the auxiliary ruled lines 251 and 252 are spaced apart from each other at a predetermined interval, and the auxiliary ruled line 261 is separated from the four corners of the auxiliary ruled lines 251 and 252 at a predetermined interval (FIG. 5A). (See (b)).

  That is, since the auxiliary ruled lines 251, 252, and 261 are individually provided, the portions outside the unsealing area 21A in the sheet member 20 are individually directed in the direction opposite to the overlapping direction T of the members 20 and 30. It can be deformed (see FIGS. 5A and 5B).

Thereby, the sheet | seat member 20 can be easily deform | transformed by the state which protrudes in cross-sectional substantially convex shape toward the outer side opposite to the overlapping direction T of members 20 and 30. FIG.
Since the configuration of the auxiliary ruled lines 251, 252, and 261 other than the individual attachments is substantially the same as that of the first embodiment, substantially the same operations and effects as those of the first embodiment can be achieved.

Example 3
In Example 1 or 2 described above, the example in which the unsealed area 21A set in the sheet member 20 is formed in a substantially rectangular shape in plan view has been described. However, as shown in FIG. 6, the unsealed area 21B is formed in a substantially square shape in plan view. The folded opening package 10 of Example 3 is demonstrated.

  6A and 6B are explanatory views of the folded and opened package 10 of the third embodiment. Specifically, FIG. 6A is a perspective view of the folded and opened package 10 viewed from the sheet member 20 side, and FIG. 6B is a folded view. It is the top view which looked at the opening packaging body 10 from the sheet | seat member 20 side.

  The folded open package 10 of Example 3 is formed so that the open area 21B set in the sheet member 20 is formed in a substantially square shape in plan view and has a smaller area than the open area 21A of Example 1 (FIG. 6 (a) (b)).

  The area of the unsealing area 21A of the first embodiment is larger than the area of the unsealing area 21B of the third embodiment, and the sheet member 20 can be greatly deformed. That is, since the volume of the accommodating portion 40 can be increased corresponding to the deformation of the sheet member 20, a large amount of the contents C can be accommodated (see FIGS. 6A and 6B).

On the other hand, since the area of the unsealing region 21B is smaller than the area of the unsealing region 21A and the deformation of the sheet member 20 is small, the volume of the accommodating portion 40 is smaller than that of the first embodiment, but the content C is small. Suitable for housing.
Since the configuration other than forming the unsealed region 21B in a substantially square shape in plan view is substantially the same as that of the first embodiment, it is possible to achieve operations and effects substantially equal to or greater than or equal to those of the first embodiment.

Example 4
In the above-described first to third embodiments, the example in which the portions corresponding to the auxiliary ruled lines 25 and 26 in the sheet member 20 are modified has been described. However, as illustrated in FIG. 7, the portions other than the auxiliary ruled lines 25 and 26 are modified. The folded open package 10 of Example 4 will be described.

  FIG. 7 is an explanatory diagram of the ruled line attaching device 50 for attaching the surrounding auxiliary ruled line 25 and the linear auxiliary ruled line 27. Specifically, FIG. 7A shows the enclosed auxiliary ruled line 25 and the linear auxiliary ruled line in the sheet member 20. 7B is an enlarged cross-sectional view of a portion provided with 27, and FIG. 7B is an enlarged cross-sectional view of a state in which a portion corresponding to between the auxiliary ruled lines 25 and 27 in the sheet member 20 is deformed.

  The ruled line attaching device 50 of the fourth embodiment includes a double-edged ruled line provided blade 51 for attaching the auxiliary ruled line 251 (252) of the surrounding auxiliary ruled line 25 and a single-edged blade for attaching the auxiliary ruled line 271 (272) of the linear auxiliary ruled line 27. The ruled blade 52 is attached to the lower surface of the upper die 501 disposed above (see FIG. 7A).

  On the mounting surface of the lower mold 502 disposed below the upper mold 501, a convex portion 503 having a substantially convex shape in plan view formed in a size and shape corresponding to the space between the auxiliary ruled lines 25 and 27 is provided with the ruled line. It is mounted or formed on a portion corresponding to the space between the blades 51 and 52. The convex portion 503 is formed in a substantially arc-shaped cross section having a smooth curve (see FIG. 7A).

  The cutting edges of the ruled lined blades 51 and 52 are formed in a cutting edge shape corresponding to the cross-sectional shape of the auxiliary ruled lines 251 (252) and 271 (272). Further, the height of the convex portion 503 is formed to be substantially the same as or thicker than the thickness of the sheet member 20.

  When attaching the auxiliary ruled lines 25, 27 to the sheet member 20, the ruled lined blades 51, 52 of the upper mold 501 are pressed against the sheet member 20 placed on the lower mold 502 to enclose the auxiliary auxiliary ruled lines 25 in the sheet member 20. The flat portion between the auxiliary ruled line 251 (252) and the auxiliary ruled line 271 (272) of the linear auxiliary ruled line 27 is directed outward by the convex portion 503 opposite to the overlapping direction T of the members 20 and 30. It deforms into a substantially arcuate cross section (see FIG. 7A).

  When the pressing of the ruled-lined blades 51 and 52 against the sheet member 20 is released and the ruled-lined blades 51 and 52 are separated from the sheet member 20, the surrounding auxiliary ruled line 25 and the linear auxiliary ruled line 26 in the sheet member 20 are provided. And the flat portion between the surrounding auxiliary ruled line 25 and the linear auxiliary ruled line 27 are synergistic with a cross-sectional shape that curves in an arc toward the outside opposite to the overlapping direction T of the members 20 and 30. (See FIGS. 7A and 7B).

Thereby, the capacity | capacitance of the accommodating part 40 can be further enlarged rather than deform | transforming the part which attached the surrounding auxiliary ruled line 25 and the linear auxiliary ruled line 26. FIG.
As a result, it is possible to further increase the capacity of the contents C accommodated in the accommodating portion 40 without changing the size of the folded open package 10.

  Since the configuration of the sheet member 20 other than the deformation between the auxiliary ruled lines 25 and 27 is substantially the same as that of the first embodiment, it is possible to achieve operations and effects substantially equal to or greater than those of the first embodiment. .

(Example 5)
In the first to fourth embodiments described above, an example in which both the surrounding auxiliary ruled line 25 and the linear auxiliary ruled line 26 are provided has been described. However, as shown in FIG. 8, only the deformation auxiliary ruled line 24B having a substantially arc shape in plan view is provided. The folded opened package 10 of Example 5 will be described.

  FIG. 8 is an explanatory view of the folded and opened package 10 of the fifth embodiment. Specifically, FIG. 8A is a perspective view of the folded and opened package 10 viewed from the sheet member 20 side, and FIG. It is the top view which looked at the opening packaging body 10 from the sheet | seat member 20 side.

The folded unwrapped package 10 of Example 5 has an unpenetrated notch 232 that is broken when the sheet member 20 is folded to a predetermined folding angle θ2 or less at the opening portion 22 in the opening region 21A set in the sheet member 20. Is forming.
The cut 232 is shorter than the cut 231 of the first embodiment, and is formed to have a length attached to the inside of the opening region 21A (see FIGS. 3A, 8A, and 8B).

  The deformation auxiliary ruled line 24B having a substantially arc shape in plan view is attached to both sides of the unsealing region 21A set in the sheet member 20 with a vertical line passing through the central portion in the short direction S of the sheet member 20 as a virtual reference line (not shown). (See FIG. 8B).

  The deformation auxiliary ruled line 24B is formed in a shape that is curved in an arc shape toward the central part in the short direction S of the sheet member 20, and both sides of the unsealing area 21A in which the central part of the deformation auxiliary ruled line 24B is set in the sheet member 20 It is spaced apart from the edge at a predetermined interval (see FIG. 8B).

  Both end portions of the deformation auxiliary ruled line 24B provided on one side (left side) and the other side (right side) of the sheet member 20 are respectively at the corners on one side (left side) and the other side (right side) of the sheet member 20. Connected.

  That is, the sheet member 20 is deformed in a direction opposite to the overlapping direction T between the members 20 and 30 by deforming a portion outside the unsealing region 21A in the sheet member 20, and the overlapping direction between the members 20 and 30 is changed. It is deformed so as to protrude in a substantially convex shape in cross section toward the outside opposite to T (see FIG. 8A).

  As a result, the portion provided with the opening portion 22 in the opening region 21A formed between the deformation auxiliary ruled lines 24B in the sheet member 20 is hardly deformed, and the opening function of the opening portion 22 is prevented from being broken or damaged. be able to.

  In addition, the number of ruled lines to be provided is smaller than that of the folded and opened package 10 of the first embodiment, and a portion corresponding to the two deformation auxiliary ruled lines 24B is deformed, so that a predetermined amount of contents C are accommodated. It can be easily deformed to the volume required for

  Further, at both end portions of the sheet member 20 in the short direction S perpendicular to the central portion in the longitudinal direction L, a recessed portion 201 that is recessed from the both end portions in the short direction S toward the central portion is formed. (See FIGS. 8A and 8B).

That is, since both end portions in the short direction S orthogonal to the center portion in the longitudinal direction L of the sheet member 20 are formed narrower than the other portions by the amount of the recessed portion 201, the longitudinal length in the sheet member 20 is increased. The rigidity of the center part in the direction L is weaker than that of the other parts, and the operation of folding the folded unsealed package 10 in a folded state can be easily performed.
Since the configuration other than the deformation auxiliary ruled line 24 </ b> B and the hollow portion 201 is substantially the same as that of the first embodiment, it is possible to achieve operations and effects substantially equal to or greater than those of the first embodiment.

(Example 6)
In the above-described fifth embodiment, the example in which the two auxiliary deformation ruled lines 24B are provided has been described. However, as shown in FIG. 9, the folded and opened packaging body of the sixth example in which four additional auxiliary ruled lines 24B to 24D are provided. 10 will be described.

  FIG. 9 is an explanatory view of the folded unwrapped package 10 of Example 6. Specifically, FIG. 9A is a plan view of the folded unwrapped package 10 viewed from the sheet member 20 side, and FIG. 9B is folded. It is the top view which looked at the opening packaging body 10 from the sheet | seat member 20 side.

  9A, the deformation auxiliary ruled line 24C having a substantially arc shape in plan view shorter than the deformation auxiliary ruled line 24B is arranged on both sides of the opening area 21B having a substantially square shape in plan view set on the sheet member 20. It is attached symmetrically with respect to the space between the deformation auxiliary ruled lines 24B.

  9 (b), the deformation auxiliary ruled line 24D having a substantially arc shape in plan view shorter than the deformation auxiliary ruled line 24B has four corners on the sheet member 20 and four corners on the enclosed auxiliary ruled line 25. It is attached between the parts.

That is, the sheet member 20 is deformed in a direction opposite to the overlapping direction T between the members 20 and 30 by deforming a portion of the sheet member 20 outside the unsealing region 21 </ b> B, so that the sheet member 20 is overlapped in the overlapping direction between the members 20 and 30. It is deformed so as to protrude in a substantially convex shape in cross section toward the outer side opposite to T.
Since the configuration other than that provided with the deformation auxiliary ruled lines 24B to 24D is substantially the same as that of the first embodiment, it is possible to achieve operations and effects substantially equal to or greater than those of the first embodiment.

  And between the both ends of the notch | incision 232 formed in the opening part 22 in the opening area | region 21B in the sheet | seat member 20, and the both-side edge part inside the peripheral part which joined member 20,30 in this sheet | seat member 20 between In addition, a curved or linear folding ruled line 202 for assisting the folding of the sheet member 20 is provided (see FIGS. 9A and 9B).

  The folding ruled line 202 is attached to the predetermined angle θ1 described in the first embodiment, with a line perpendicular to the central portion in the longitudinal direction L of the opening region 21B set in the sheet member 20 as a reference line (FIG. 9A ) (B)).

  That is, when the folded and opened package 10 is folded in a folded state, the folding of the folded and opened package 10 is assisted by the folding ruled line 202, so that the folding resistance when folded in two is reduced.

  Accordingly, the folded and opened package 10 can be accurately and easily folded in a folded state, and the notch 232 formed in the opening portion 22 in the opening region 21B of the sheet member 20 can be reliably broken and opened. it can.

(Example 7)
In the above-described sixth embodiment, an example in which the deformation auxiliary ruled lines 24B to 24D having a substantially arc shape in a plan view and a surrounding auxiliary ruled line 25 having a substantially rectangular shape in a plan view has been described. However, as illustrated in FIG. The folding unwrapped packaging body 10 of Example 7 provided with the deformation auxiliary ruled line 24E or the surrounding auxiliary ruled line 25E having a substantially rhombus in plan view will be described.

  FIG. 10 is an explanatory view of the folded and opened package 10 of Example 7. Specifically, FIG. 10A is a plan view of the folded and opened package 10 viewed from the sheet member 20 side, and FIG. 10B is a folded. It is the top view which looked at the opening packaging body 10 from the sheet | seat member 20 side.

  10 (a) has a deformation auxiliary ruled line 24E that is substantially linear in a plan view on both sides of an opening region 21B set in the sheet member 20 in parallel with the longitudinal direction L of the sheet member 20. It is attached.

The folded open package 10 in FIG. 10 (b) is surrounded by a generally rhombus in plan view that is slightly larger than the unsealed region 21C around the open region 21C having a generally rhombus in plan view set in the central plane portion of the sheet member 20. An auxiliary ruled line 25E is attached.
Between the four corners of the sheet member 20 and the oblique sides of the four sides of the surrounding auxiliary ruled line 25E, straight or curved deformation auxiliary ruled lines 24E are respectively attached.

  That is, the sheet member 20 is deformed in a direction opposite to the overlapping direction T of the members 20 and 30 with respect to the opening regions 21B and 21C of the sheet member 20 so that the sheet member 20 overlaps the members 20 and 30. It is deformed so as to protrude in a substantially convex shape in cross section toward the outside opposite to the alignment direction T (see FIGS. 10A and 10B).

  As a result, the deformation is made between the portion provided with the opening portion 22 in the opening area 21B formed between the deformation auxiliary ruled lines 24E and the portion provided with the opening portion 22 in the opening area 21C surrounded by the surrounding auxiliary ruled lines 25E. It is hard to occur, and it can prevent that the opening function of the opening part 22 is broken or damaged.

Since the configuration other than the attachment of the auxiliary deformation ruled lines 24E and 25E is substantially the same as that of the first embodiment, the operation and effect equivalent to or higher than those of the first embodiment can be achieved.
In addition, the notch 232 is formed in the opening part 22 in the opening area | regions 21B and 21C in the sheet | seat member 20. FIG. Bending ruled lines 202 are provided on both sides of the cut 232.

(Example 8)
In the above-described Examples 1 to 7, the example in which the folded open package 10 is formed in a substantially rectangular shape in plan view has been described. However, as shown in FIG. 11, the folded open package in Example 8 formed in a substantially elliptical shape in plan view. The body 10 will be described.

  FIG. 11 is an explanatory view of the folded and opened package 10 of the eighth embodiment. Specifically, FIG. 11A is a perspective view of the folded and opened package 10 viewed from the sheet member 20 side, and FIG. It is the top view which looked at the opening packaging body 10 from the sheet | seat member 20 side.

  In the folded and opened package 10 of Example 8, the sheet member 20 and the film member 30 are formed in a substantially elliptical shape in plan view, and the opening region 21D having a substantially elliptical shape in plan view is set in the central plane portion of the sheet member 20. (See FIGS. 11 (a) and 11 (b)).

  Around the opening area 21D, a surrounding auxiliary ruled line 25F having a substantially elliptical shape in plan view that is slightly larger than the opening area 21D is provided. A linear auxiliary ruled line 27 </ b> F having a substantially elliptical shape in plan view that is slightly smaller than the sheet member 20 is attached to a part inside the peripheral edge of the sheet member 20 (see FIGS. 11A and 11B).

  That is, the portion outside the opening region 21D in the sheet member 20 is overlapped with the members 20 and 30 while the portion in the opening region 21D surrounded by the surrounding auxiliary ruled line 25F in the sheet member 20 is maintained in a substantially flat state. The sheet member 20 is deformed in the direction opposite to the alignment direction T, and the inner portion of the sheet member 20 protrudes in a substantially convex shape toward the outer side opposite to the overlapping direction T of the members 20 and 30. It has been transformed into a state (see FIGS. 11A and 11B).

  Since the configuration other than the bent opened packaging body 10 formed in a substantially elliptical shape in plan view is substantially the same as that of the first embodiment, it is possible to achieve operations and effects substantially equal to or greater than those of the first embodiment. .

  Moreover, compared to the folded and opened package 10 having an angular portion as in the first embodiment, the contents C are less likely to remain at the peripheral portion of the folded and opened package 10 having a substantially elliptical shape in plan view, and almost all the contents. C can be taken out. Further, when the finger is picked and bent, the finger can be prevented from being damaged, and the pain felt when the finger is bent can be alleviated.

A notch 232 is formed in the opening portion 22 in the opening region 21D of the sheet member 20. Bending ruled lines 202 are provided on both sides of the cut 232.
Moreover, although Example 1-7 demonstrated the example which formed the folding opening packaging body 10 in planar view substantially rectangular shape and planar view substantially ellipse, if it is a shape which can be folded in a two-folded state, folding opening packaging body 10 You may form in desired shapes other than an Example.

Example 9
In Examples 1 to 8 described above, the example in which the opening portion 22 is provided in the central portion of the sheet member 20 has been described. However, as shown in FIG. 12, the opening portion 22 is provided in a portion other than the central portion of the sheet member 20. Next, the folded and opened package 10 of Example 9 will be described.

  FIG. 12 is an explanatory view of the folded open package 10 according to the ninth embodiment. Specifically, FIG. 12 (a) shows the folded open package 10 in which the open portion 22 is provided at the corner-side flat portion of the sheet member 20. FIG. 12B is a plan view as seen from the sheet member 20 side. FIG. 12B is a plan view of the folded unwrapped package 10 in which the opening portion 22 is provided on the short side plane portion of the sheet member 20.

  12 (a) is provided with an opening portion 22 in an opening region 21E having a substantially triangular shape in plan view, which is set at the corner corner side plane portion of the sheet member 20, and the deformation auxiliary ruled line 24F is provided on the sheet member. A plurality of lines are provided between the three side edges in 20 and the one side edge in the unsealing region 21E, and some of the deformation auxiliary ruled lines 24F are crossed and attached.

  12 (b) is provided with an opening portion 22 in an opening region 21F having a substantially rectangular shape in plan view, which is set near the short side plane portion of the sheet member 20, and the deformation auxiliary ruled line 24F is provided on the sheet. A plurality of corners are provided between the four corners of the member 20 and the peripheral edge of the surrounding auxiliary ruled line 25 provided around the opening area 21F.

  That is, the sheet member 20 is overlapped with the members 20 and 30 in order to deform the portion provided with the deformation assist ruled line 24F in the sheet member 20 in the direction opposite to the overlapping direction T between the members 20 and 30. It can deform | transform into the state which protrudes in a cross-sectional substantially convex shape toward the outer side opposite to the direction T (refer Fig.12 (a) (b)).

As a result, the opening portion 22 is provided at a desired location in the sheet member 20, and the desired number, number, and shape of the accommodating portion 40 are formed by providing the desired number of deformation auxiliary ruled lines 24F at the desired location. can do.
In addition, you may attach the surrounding auxiliary ruled line 25 so that this opening area | region 21E may be enclosed with respect to the circumference | surroundings of the opening area | region 21E shown to Fig.12 (a).

Since the configuration other than the provision of the opening portion 22 at a desired location in the sheet member 20 is substantially the same as that of the first embodiment, it is possible to achieve operations and effects substantially equal to or greater than those of the first embodiment.
In addition, the notch 232 is formed in the opening part 22 in the opening area | regions 21E and 21F in the sheet | seat member 20. FIG. Bending ruled lines 202 are provided on both sides of the cut 232.

(Example 10)
In the above-described first embodiment, an example in which the unpenetrated cut 231 is broken and opened by bending the sheet member 20 has been described. However, as shown in FIGS. 13 and 14, the penetrated cut formed in the unsealed portion 22. The folded opening package 10 of Example 10 which breaks and opens the sealing material 28 covered so as to cover 233 will be described.

  FIG. 13 is an explanatory view of the folded and opened package 10 of Example 10. Specifically, FIG. 13A is a perspective view of the folded and opened package 10 viewed from the sheet member 20 side, and FIG. 13B is a folded. It is the top view which looked at the opening packaging body 10 from the sheet | seat member 20 side.

  FIG. 14 is an explanatory view when the contents C are taken out from the folded open package 10, and more specifically, the contents C are taken out from the notch 233 of the opening portion 22 opened by breaking the sealing material 28 in the sheet member 20. It is a partial expanded sectional view at the time.

  The folded and opened packaging body 10 of Example 10 is formed by penetrating the notch 233 in the opening direction 22 in the opening region 21A set in the sheet member 20 in the thickness direction, and the sealing material 28 made of aluminum foil, When the sheet member 20 is bent, the sheet member 20 is attached so as to cover the notch 233 of the opening portion 22 in the opening region 21 </ b> A with respect to the surface that becomes the mountain side. The sealing material 28 is formed to have a thickness that is broken when the sheet member 20 is bent to a predetermined bending angle θ2 or less (see FIGS. 3A, 13A, and 13B).

  That is, the sealing material 28 attached so as to cover the notch 233 of the opening portion 22 in the opening region 21 </ b> A in the sheet member 20 just by folding the folded and opened packaging body 10 in a half-folded state is in the process of bending the sheet member 20. Can be easily and easily broken (see FIG. 14).

  Moreover, until the sealing material 28 is broken and opened, the notch 233 of the opening portion 22 is not opened, and the contents C stored in the storage portion 40 are reliably prevented from leaking to the outside. In addition, for example, foreign matter such as dust and insects can be prevented from entering the housing portion 40 through the notch 233 of the opening portion 22.

Further, the sheet member 20 is bent to a predetermined bending angle θ2 or less, and the arc-shaped tongue piece 233a in the cut 233 protrudes obliquely outward, so that the content C flowing out of the cut 233 enters the tongue piece 233c. It is pushed out while contacting (see FIG. 14).
Thereby, the content C is hard to be pushed out at once, and it can prevent more reliably that the content C scatters around.

Since the configuration other than the sticking of the sealing material 28 is substantially the same as that of the first embodiment, it is possible to achieve operations and effects substantially equal to or greater than those of the first embodiment.
Note that folding ruled lines 202 that assist folding are attached to both sides of the notch 233 in the sheet member 20.

(Example 11)
In Example 10 described above, an example in which the sealing material 28 is broken and opened is described. However, as shown in FIG. 15, as shown in FIG. The folded open package 10 will be described.

  FIG. 15 is an explanatory view of the folded open package 10 of Example 11. Specifically, FIG. 15 (a) is a plan view of the folded open package 10 viewed from the sheet member 20 side, and FIG. It is sectional drawing which divided the opening package 10 in the center part of the transversal direction S. FIG.

  In the folded open package 10 of Example 11, the breakage assisting sheet 29 that assists the breakage of the sealing material 28 was adhered so as to cover the notch 233 of the opening portion 22 in the opening region 21A set in the sheet member 20. Then, the sealing material 28 is stuck so that the notch 233 of the opening part 22 may be covered with respect to the upper surface of the fracture | rupture reinforcement sheet | seat 29 (refer Fig.15 (a) (b)).

  The break assisting sheet 29 is formed in a size smaller than the opening region 21A of the sheet member 20 and larger than the sealing material 28, and has a thickness equivalent to or greater than or equal to that of the sheet member 20. Furthermore, the cut assisting sheet 29 is formed with a notch 233 in the opening portion 22 penetrating in the thickness direction (see FIGS. 15A and 15B).

  That is, since the portion other than the notch 233 formed in the opening portion 22 in the opening region 21A set in the sheet member 20 is reinforced by the breakage reinforcing sheet 29, the folded opening package 10 is folded in two. It is possible to prevent the sheet member 20 and the fracture reinforcing sheet 29 from being bent into a mountain shape at a portion other than the notch 233 when the sheet member 20 and the fracture reinforcing sheet 29 are bent.

  Moreover, since the radius of curvature of the surface that becomes the peak side when the auxiliary break sheet 29 is folded is larger than the radius of curvature of the surface that becomes the peak side when the sheet member 20 is bent, the inside of the opening region 21A set in the sheet member 20 The sealing material 28 covered so as to cover the notch 233 of the opening portion 22 can be more reliably broken and opened.

Since the configuration other than the attachment of the breakage reinforcing sheet 29 is substantially the same as that of the tenth embodiment, it is possible to achieve operations and effects substantially equal to or greater than those of the tenth embodiment.
Note that folding ruled lines 202 that assist folding are attached to both sides of the notch 233 in the sheet member 20.

  Further, for example, the breakage assisting sheet 29 is formed in a size and shape substantially the same as that of the sealing material 28, or a size covering the central plane portion surrounded by the surrounding assist ruled line 25 in the sheet member 20, and You may form in a shape. Furthermore, you may stick the fracture | rupture auxiliary | assistant sheet | seat 29 to the back surface side corresponding to the accommodating part 40 in the sheet | seat member 20. FIG.

(Example 12)
In the above-described Examples 1 to 11, as another example of the unsealing structure in which the notches 231 and 232 of the opening portion 22 are broken or the sealing material 28 covering the notches 233 is broken and opened, as shown in FIG. Next, the folded and opened package 10 of Example 12 that peels and opens the opening 22 will be described.

  FIG. 16 is an explanatory view of the folded and opened package 10 of Example 11. Specifically, FIG. 16 (a) is an enlarged cross-sectional view of the opening portion 22 that peels and opens in the sheet member 20, and FIG. It is a partial expanded sectional view at the time of taking out the contents C from the notch 233 of the opening part 22 which peeled and opened.

  In the folded and opened package 10 of Example 12, the cut 233 is constituted by a cut 233a formed in the sheet base portion 20a of the sheet member 20 and a cut 233b formed in the sealing material 20b on the front side.

The facing surfaces in the opening region 21A corresponding to the space between the notches 233a and 233b in the sheet base 20a and the sealing material 20b are re-peeled by an adhesive layer N1 having a releasable adhesive force interposed between the facing surfaces. Affixed as possible.
The facing surfaces outside the unsealed region 21A are bonded to each other so as not to be peeled by an adhesive layer N2 having a non-removable adhesive force interposed between the facing surfaces (see FIG. 16A).

  The folded and opened packaging body 10 is folded in a folded state, and the opposing surfaces in the opening region 21A corresponding to the gap between the sheet base 20a and the notches 233a and 233b in the sealing material 20b are resisted to the adhesive strength of the adhesive layer N1. Therefore, the sheet base 20a and the cuts 233a and 233b in the sealing material 20b can be communicated with each other (see FIG. 16B).

  Accordingly, the cuts 231 and 232 of Examples 1 to 11 are broken or the sealing material 28 covering the cut 233 is broken and opened, so that the gap between the cuts 233a and 233b in the sheet base 20a and the sealing material 20b is reduced. And corresponding portions can be peeled and opened easily and easily.

  As a result, the contents C accommodated in the accommodating portion 40 can be smoothly taken out from the cuts 233a and 233b that are separated from each other and communicated with the unsealed portion 22 of the sheet member 20.

Moreover, when the peeled and stuck part between the notches 233a and 233b is opened, the contents C flowing out from the notches 233a and 233b are pushed out while contacting the tongue piece 233c. It is difficult to extrude and the contents C can be prevented from scattering around.
Since the configuration other than peeling and unsealing the opening portion 22 is substantially the same as that of the tenth embodiment, it is possible to achieve operations and effects substantially equal to or greater than those of the tenth embodiment.

(Example 13)
In the above-described Examples 1 to 12, the example in which one accommodating portion 40 is formed has been described. However, as shown in FIG. 17, the folded and opened packaging body 10 in Example 13 in which two accommodating portions 40 are formed will be described. .
FIG. 17 is an explanatory view of the folded and opened package 10 of the eleventh embodiment. Specifically, the figure is a plan view of the folded and opened package 10 including the two accommodating portions 40 as viewed from the sheet member 20 side.

  The folded unwrapped package 10 of Example 13 is configured such that the accommodating portion 40 is formed between the opposing surfaces on the upper side of the central portion in the longitudinal direction L where the members 20 and 30 are overlapped with each other, and between the opposing surfaces on the lower side. Yes. The opening part 22 which has the notch 232 is formed in the opening area | region 21A set to the center part (specifically between the adjacent accommodating parts 40) of the longitudinal direction L in the sheet | seat member 20 (refer FIG. 17).

Folding and opening the folded packaging body 10 in a folded state, breaking the notch 232 formed in the opening portion 22 in the opening region 21A of the sheet member 20 and opening it, the two adjacent accommodation portions 40 are communicated with each other. Can do.
As a result, the contents C accommodated in the two accommodating portions 40 can be taken out from the cuts 232 that have been broken and opened substantially simultaneously with the folding operation of the folded open package 10.

Since the configuration other than the formation of the two accommodating portions 40 is substantially the same as that of the first embodiment, it is possible to achieve operations and effects substantially equal to or greater than those of the first embodiment.
In addition, you may stick the sealing material 28 so that the cut 231 (232) formed in the opening part 22 of the sheet | seat member 20 may be covered. Moreover, you may provide the notch 233 instead of the notch 231 (232).

However, as shown in FIG. 18, the opposing peripheral portions of the pair of film members 30 are joined. The 14 folded open package 10 will be described.

  FIG. 18 is an explanatory view of the folded and opened package 10 of Example 14. Specifically, FIG. 18A shows the folded and opened package 10 in which the sheet member 20 is sandwiched between a pair of film members 30 in the short direction. FIG. 18B is a cross-sectional view divided at the center of S, and FIG. 18B shows the folded unsealed package 10 in which the sheet member 20 is attached to one film member 30 of the pair of film members 30 at the center in the short direction S. It is sectional drawing divided.

  18 (a), the folded unwrapped package 10 includes a sheet member 20 sandwiched between a pair of film members 30 and a pair of film members 30 facing each other outside the peripheral edge of the sheet member 20. The peripheral edge is joined integrally.

  18B, the sheet member 20 is bonded to the surface side of one film member 30 of the pair of film members 30, and the peripheral portion of the sheet member 20 in the pair of film members 30. The opposed peripheral edges that are overlapped on the outer side are integrally joined.

That is, it is more preferable to join the opposing peripheral portions of the film members 30 having a smaller thickness than the sheet member 20 rather than joining the opposing peripheral portions having different thicknesses in the sheet member 20 and the film member 30 as in the first embodiment. It is possible to join at higher speed.
Since the configuration other than the joining of the opposing peripheral edge portions of the pair of film members 30 is substantially the same as that of the first embodiment, it is possible to achieve operations and effects substantially equal to or greater than those of the first embodiment.
