Description

  The present invention relates to a pouch container and a pouch container package.

  As a packaging body for storing articles such as cosmetics, stationery, and batteries, a blister pack composed of a plate material such as cardboard and a resin molded body formed so as to follow the shape of the article is widely known (for example, Patent Document 1). In recent years, from the viewpoint of cost reduction, waste reduction, and the like, a packaging form in which articles are stored in a pouch container such as a standing pouch instead of a blister pack has been proposed (for example, see Patent Document 2).

Japanese Patent Laying-Open No. 2015-013660 JP, 2015-107322, A

  By the way, in a packaging form in which an article is stored in a pouch container, which is a soft packaging material, the movement of the article is less constrained than in a blister pack. For example, the article is moved to the target position in the container. May not be retained. Further, in a packaging form in which a display unit for a product name or the like provided on an article is viewed from the outside, the article may move or rotate and it may be difficult to hold the target display unit at a desired position. This is particularly noticeable when the shape of the article is cylindrical.

A pouch container according to the present invention is a pouch container in which at least one article is accommodated, and includes a first wall surface sheet, a second wall surface sheet opposed to the first wall surface sheet, and the first wall surface sheet. An intermediate gusset sheet having a first surface sheet facing the second surface sheet and a second surface sheet facing the second wall surface sheet, and provided along the lateral direction on the inner surface of each wall surface sheet, the intermediate gusset sheet has a through hole that can inserting the article, possess a biasing portion, the urging of the article to be inserted into the through hole, wherein the inner surface of each wall sheet, and the intermediate gusset sheet A bottom gusset sheet is formed which is bonded to the lower side and forms a container bottom surface portion on which the article is placed, and a connection portion between the bottom gusset sheet and each wall sheet is provided at a lower end inner edge portion and both sides thereof. Slant Includes a inner portion, the lateral length of the inner edge of the lower end portion is 1.05 times to 1.50 times the transverse diameter of the article, characterized in that.

  The pouch container package according to the present invention includes the pouch container and at least one article accommodated in the pouch container.

In the pouch container according to the present invention, the intermediate gusset sheet functions as an article holding unit, and movement and rotation of the article in the container are suppressed. Accordingly, the article can be held at a target position in the container. Further, when the display portion of the article is viewed from the outside, it is possible to prevent the target display portion from being invisible due to the rotation of the article. Therefore, even if the shape of the article is a cylindrical shape, it can be suitably used. Also, by setting the lateral length of the lower edge of the bottom gusset sheet to the lateral diameter of the article within a range that is 1.05 to 1.50 times the lateral diameter of the article, for example, The lateral length of the portion of the container bottom portion that is developed to be substantially flat at the time of storage is substantially the same as the lateral diameter of the article, so that the retainability of the lower part of the article is improved.

An example of an embodiment will be described in detail with reference to the drawings.
In the embodiment, an article 30 (see FIG. 4) is illustrated as an article accommodated in a pouch container. The article 30 is a container that has a substantially cylindrical body 31 and is filled with contents. However, the article is not limited to this, and the pouch container may contain a container having a shape other than a cylindrical shape (for example, a prismatic shape, an elliptical shape, etc.), or may contain an article other than the container. . In the present specification, the description of “substantially **” is intended to include not only a complete columnar shape but also a material that is substantially recognized as a columnar shape, taking a substantially columnar shape as an example.

  In the embodiment, a standing pouch provided with a bottom gusset sheet is illustrated, but the configuration of the present invention may be applied to other pouch forms such as a flat pouch having no self-supporting property. In this specification, when the pouch container is erected on a flat surface, the vertical direction (longitudinal direction in FIG. 1) is “up and down direction”, the vertical lower side is “down”, and the vertical upper side is “up”. The width direction of the pouch container (the left-right direction in FIG. 1) is referred to as “lateral direction”, and the front-rear direction of the pouch container is described as “front-back direction”. In the drawings, the vertical direction is indicated as X, the horizontal direction as Y, and the front and back direction as Z.

Drawing 1 is a front view of pouch container 10 which is an example of an embodiment.
As shown in FIG. 1, the pouch container 10 includes a top sheet 11 (first wall sheet), a back sheet 12 (second wall sheet) disposed opposite to the top sheet 11, and each wall sheet (top sheet 11 and An intermediate gusset sheet 20 provided along the lateral direction Y is provided on the inner surface of the back sheet 12). Each wall sheet is a sheet material that forms a front surface portion and a back surface portion of the container. The intermediate gusset sheet 20 includes a first surface sheet 22 </ b> A facing the top sheet 11 and a second surface sheet 22 </ b> B facing the back sheet 12. The intermediate gusset sheet 20 is a downward gusset sheet in which the lower end of the first side sheet 22A and the lower end of the second side sheet 22B are connected to each other. It is preferred to have crease lines 21 formed along. As will be described in detail later, the intermediate gusset sheet 20 has a function of holding the article 30 while suppressing movement and rotation of the article 30 in the container.

  The pouch container 10 includes a bottom gusset sheet 13 that is detachably joined to the inner surface of each wall surface sheet below the intermediate gusset sheet 20 and forms a bottom surface portion 13b on which the article 30 is placed. The pouch container 10 is a standing pouch that allows the bottom gusset sheet 13 to be unfolded when the article 30 is accommodated. The pouch container 10 includes at least two gusset sheets, one of which functions as a holding section that holds the article 30, and the other of which functions as a bottom gusset section that forms a container bottom surface section. The bottom gusset sheet 13 includes a first face sheet 13A that faces the top sheet 11 and a second face sheet 13B that faces the back sheet 12. Contrary to the intermediate gusset sheet 20, the bottom gusset sheet 13 is an upward gusset sheet in which the upper end of the first side sheet 13A and the upper end of the second side sheet 13B are connected to each other, and the first side sheet 13A and the second side sheet. 13B has a crease line 13a formed along the horizontal direction Y. The pouch container 10 has a flat shape in which the wall sheets are substantially in contact with each other in a state where the article 30 is not accommodated, and the gusset sheets are folded.

  The pouch container 10 has side seal portions 14 formed along the vertical direction X at both ends in the lateral direction of the wall sheets arranged to face each other. It is preferable that the lateral end edges of the bottom gusset sheet 13 and the intermediate gusset sheet 20 reach the lateral end edges of each wall sheet, and the side seal portion 14 includes the bottom gusset sheet 13 and the It is formed with the intermediate gusset sheet 20 inserted. The side seal portion 14 joins the wall sheets to each other and joins the wall sheets and the two gusset sheets. In addition, a bottom seal portion 16 that is a joint portion between the bottom gusset sheet 13 and each wall surface sheet is formed in the lower portion of the pouch container 10. The bottom gusset sheet 13 is formed with notches 17 at both ends in the lateral direction, and the respective wall surface sheets are directly joined via the notches 17.

  In the present embodiment, the upper end of the pouch container 10 is open, and after the article 30 is accommodated in the container from the upper end opening, the upper seal portion 15 (see FIG. 4) is formed along the upper end of each wall sheet. Formed and sealed inside the container. In the upper seal portion 15, for example, a suspension hole 19 is formed through each wall sheet at the lateral center α of the pouch container 10. In addition, it is good also as a structure which can provide a zipper member etc. and can be resealed after opening.

  Each wall sheet has a substantially rectangular shape that is long in the vertical direction X, for example. The bottom gusset sheet 13 has a substantially rectangular shape that is long in the lateral direction Y, and is preferably provided over the entire lateral length (full width) of the pouch container 10 as described above. Similarly to the bottom gusset sheet 13, the intermediate gusset sheet 20 has a shape that extends long in the lateral direction Y, and is provided over the entire width of the pouch container 10 as described above. The pouch container 10 has a notch 18 for opening formed by cutting the side seal portion 14 of each wall sheet, for example. In the example shown in FIG. 1, two notches 18 are formed in the upper portion of the pouch container 10 in the horizontal direction Y.

  The bottom gusset sheet 13 is joined to the inner surface of each wall sheet by the bottom seal portion 16 so as to be deployable, thereby forming a bottom surface portion 13b on which the article 30 is placed. The bottom surface portion 13 b is a non-joined portion that is not joined to the wall surface sheet surrounded by the bottom seal portion 16, and is a portion that develops when the wall surface sheets are separated in the front and back direction Z when the article 30 is accommodated. The bottom seal portion 16 preferably has a lower end inner edge portion 16a and oblique side inner edge portions 16b provided on both sides thereof, and the bottom surface portion 13b is preferably formed to have a substantially trapezoidal shape when viewed from the front.

The lower end inner edge portion 16a, which is a part of the inner edge of the bottom seal portion 16, is formed, for example, substantially in parallel with the lower end of the pouch container 10 that extends straight in the lateral direction Y. In the example shown in FIG. 1, the lower end inner edge portion 16 a is formed linearly from the lateral center α of the pouch container 10 to the vicinity of the intermediate position with each side seal portion 14. Since the lower end inner edge portion 16a is formed in a straight line, when the bottom gusset sheet 13 is unfolded, the portion of the bottom surface portion 13b on which the article 30 is placed becomes substantially flat, and the article 30 can be supported more stably. It becomes. And the hypotenuse inner edge 16b is linearly formed from the both ends of the lower end inner edge 16a to the intersection of the upper end of the bottom gusset sheet 13 and each side seal part 14. The lateral length L _16a of the lower end inner edge portion 16a is preferably 1.05 to 1.50 times the lateral diameter D ₃₀ of the article 30, and preferably 1.10 times to 1.30 times. Particularly preferred. As will be described in detail later, by setting the lateral length L _16a with respect to the lateral diameter D ₃₀ within the range, for example, the lateral length of the portion of the bottom surface portion 13b that develops substantially flat when the article 30 is accommodated is set. substantially the same becomes the transverse diameter D _30, thereby improving the retention of the lower portion of the article 30.

  The intermediate gusset sheet 20 may be provided in contact with the bottom gusset sheet 13, but is preferably disposed at a position away from the bottom gusset sheet 13 from the viewpoint of improving the retainability of the article 30. In the example shown in FIG. 1, an intermediate gusset sheet 20 is disposed between the vertical central portion β of the pouch container 10 and the bottom gusset sheet 13. The intermediate gusset sheet 20 may be further disposed on the vertical center part β side or may be disposed above the vertical center part β as long as it can hold the body part 31 of the article 30. The intermediate gusset sheet 20 is rearranged according to, for example, the shape, size, etc. of the article accommodated in the container, but may be provided so that the portion in contact with the article is positioned below the vertical central portion β. preferable.

  Each sheet material which comprises the pouch container 10 is normally comprised from a resin film. The resin film constituting the sheet material is required to have basic performance as a package, such as impact resistance, wear resistance, and heat resistance. The thickness of the sheet material is, for example, 10 μm to 300 μm, preferably 20 μm to 200 μm. Moreover, since each seal part is preferably formed by heat sealing, the sheet material is also required to have heat sealability. As the sheet material, a multilayer sheet having a base film layer and a sealant layer that imparts heat sealability is preferable. When high gas barrier properties are required, a gas barrier layer is provided between the base film layer and the sealant layer. Is preferably provided. These layers can be laminated by a conventional laminating method, for example, a co-extrusion method, a dry lamination method using an adhesive, or a thermal lamination method in which a heat-adhesive layer is bonded by heat.

  In addition, the seal part formed by heat sealing is formed by thermocompression-bonding the sheet material in a state where the sealant layers of the sheet materials are opposed to each other. In the intermediate gusset sheet 20, it is preferable that the first face sheet 22 </ b> A and the second face sheet 22 </ b> B are joined at the side seal portion 14 from the viewpoint of improving the sealing performance of the pouch container 10. Accordingly, the intermediate gusset sheet 20 is preferably a double-sided heat-sealable multilayer sheet having sealant layers on both sides of the sheet.

  Examples of the film constituting the base film layer include polyester (polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polybutylene terephthalate (PBT), polycarbonate (PC), etc.), polyolefin (polyethylene (PE), polypropylene ( PP), etc.), polyamide (nylon-6, nylon-66, etc.), polyacrylonitrile (PAN), polyimide (PI), polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), polymethyl methacrylate (PMMA), poly A stretched or unstretched film of one layer or two or more layers composed of ether sulfone (PES) and ethylene-vinyl alcohol copolymer (EVOH) can be exemplified. The thickness of the base film layer is, for example, 10 μm to 200 μm, preferably 10 μm to 100 μm.

  The films constituting the sealant layer include low density polyethylene (LDPE), linear low density polyethylene (LLDPE), ethylene-propylene copolymer (EP), unstretched polypropylene (CPP), and biaxially stretched nylon (ON). , Ethylene-olefin copolymer, ethylene-acrylic acid copolymer (EAA), ethylene-methacrylic acid copolymer (EMAA), ethylene-vinyl acetate copolymer (EVA), etc. A stretched or unstretched film can be exemplified. The thickness of the sealant layer is, for example, 20 μm to 200 μm, preferably 30 μm to 180 μm.

  The gas barrier layer may be a metal thin film such as aluminum, a resin film such as vinylidene chloride (PVDC) or ethylene-vinyl alcohol copolymer (EVOH), or any synthetic resin film (for example, a base film layer). ), And a film obtained by vapor-depositing (or sputtering) an inorganic oxide such as aluminum, aluminum oxide or silica. The thickness of the gas barrier layer is, for example, 0.1 μm to 20 μm, preferably 0.2 μm to 10 μm.

  The wall sheet is provided with a design print layer (not shown) that is a display for displaying the product name, design (design), manufacturer name, product description such as raw materials and precautions, background color, etc. Is preferred. Each gusset sheet may be provided with a print layer such as a design print layer. The design print layer can be formed on the inner surface of the base film layer by a known method such as gravure printing. The design print layer is formed on a part or all of each wall sheet. In this embodiment, the structure by which the design printing layer was provided in a part of each wall surface sheet is shown. Specifically, a transparent portion 11a is provided in a part of the top sheet 11, and the display portion 33 (see FIG. 4) of the article 30 accommodated in the container can be visually recognized from the outside via the transparent portion 11a. For example, the transparent portion 11a is formed so that a specific portion on which a product name or the like is drawn can be seen from the outside of the display portion 33 provided in a wide range of the body portion 31, for example. In each drawing, for convenience of explanation, the entire wall surface sheet is illustrated as transparent, but actually, for example, the inside of the container cannot be seen from a portion other than the transparent portion 11a.

  The transparent portion 11a is formed, for example, by not providing a design print layer on a part of the top sheet 11. In addition, the design printing layer may be provided in the transparent part 11a in the range which does not impair the visibility of the display part 33 of the article | item 30. FIG. In the example shown in FIG. 1, a substantially elliptical transparent portion 11 a that is long in the vertical direction X is formed between the bottom gusset sheet 13 and the notch 18 in the top sheet 11. The arrangement, shape, dimensions, and the like of the transparent portion 11a are not particularly limited, and can be changed as appropriate according to, for example, the arrangement of the display portion of the article accommodated in the pouch container 10. Further, the transparent portion may be formed on the back sheet 12 or may be formed on both the top sheet 11 and the back sheet 12.

Hereinafter, the intermediate gusset sheet 20 will be described in detail with reference to FIGS.
FIG. 2 is a plan view of the pouch container 10 and shows a state where the intermediate gusset sheet 20 is developed. FIG. 3 is a view showing a state in which the intermediate gusset sheet 20 is extracted and completely developed, and the barrel portion 31 is indicated by an alternate long and short dash line for comparison of dimensions between the through hole 24 and the barrel portion 31 of the article 30. 4 to 6 show a pouch container package 50 in which the article 30 is accommodated in the pouch container 10.

  As shown in FIGS. 1 and 2, the intermediate gusset sheet 20 includes a through hole 24 through which the article 30 can be inserted and a biasing portion that biases the article 30 inserted through the through hole 24. The intermediate gusset sheet 20 is a downward gusset sheet in which the lower ends of the first face sheet 22A and the second face sheet 22B arranged opposite to each other are connected to each other, and the first face sheet 22A and the second face sheet 22B have substantially the same shape. The dimensions are preferably substantially the same. An upward gusset sheet may be applied to the intermediate gusset sheet 20, but when the downward gusset sheet is used, the insertion direction is regulated by the first sheet 22A and the second sheet 22B when the article 30 is accommodated, and Since the part 31 is easy to be penetrated by the through-hole 24, it is preferable.

  The intermediate gusset sheet 20 may be joined to each wall sheet at both lateral ends only by the side seal part 14, but preferably a joint part 23 to each wall sheet is formed separately from the side seal part 14. . The joining portion 23 is preferably formed from one side seal portion 14 to the other side seal portion 14 along the lateral direction Y of the intermediate gusset sheet 20. In the intermediate gusset sheet 20, the upper part of the first sheet 22 </ b> A and the inner surface of the top sheet 11 are joined by the joining part 23, and the upper part of the second sheet 22 </ b> B and the inner surface of the back sheet 12 are joined. The joint portion 23 is preferably formed by heat sealing.

The length of the intermediate gusset sheet 20 in the vertical direction (in other words, the heel width) is usually 1.1 times the front-back radius of the body portion 31 of the article 30 (in this embodiment, 1/2 of the lateral diameter D ₃₀ ). The length is ˜2.0 times, preferably 1.2 times to 1.8 times, and more preferably 1.3 times to 1.6 times. As will be described later, in this embodiment, each of the first face sheet 22A and the second face sheet 22B functions as an urging portion, so that the article 30 is inserted into the through hole 24 within this range. When it does, the expansion | deployment to the front-back direction Z of the intermediate | middle gusset sheet | seat 20 does not become large too much, and the article | item 30 and 22 A of 1st surface sheets, and 2nd surface sheet 22B can be closely_contact | adhered.

  The through hole 24 is preferably formed in the lower part of the intermediate gusset sheet 20 across the first face sheet 22A and the second face sheet 22B. It is preferable that the opening areas of the first face sheet 22A and the second face sheet 22B are substantially the same. The through hole 24 is formed, for example, by cutting the sheet into a desired shape from the lower end (the portion where the crease line 21 is formed) of the intermediate gusset sheet 20 in a folded state.

The through-hole 24 widens when the intermediate gusset sheet 20 is unfolded (see FIG. 2), and is formed with a dimension that allows the body portion 31 of the article 30 to be inserted. The intermediate gusset sheet 20 is unfolded by separating the wall surface sheets in the front-back direction Z when the article 30 is accommodated, like the bottom gusset sheet 13. In the present embodiment, one through hole 24 is formed at the center in the lateral direction of the intermediate gusset sheet 20. The through hole 24 is formed symmetrically with respect to the lateral center α of the pouch container 10 when viewed from the front. Further, the lower end inner edge portion 16a is also formed symmetrically with respect to the lateral center α of the pouch container 10 when viewed from the front. The through hole 24 is preferably formed at a position overlapping the lower end inner edge portion 16a in the vertical direction X in front view. Since the range corresponding to the lower end inner edge portion 16a of the bottom surface portion 13b expands substantially flat, by forming the through hole 24 at a position overlapping the lower end inner edge portion 16a in the vertical direction X, the bottom surface portion 13b expands substantially flat. Article 30 can be placed on the part. In the present embodiment, the lateral length D ₂₄ of the through hole 24 (see FIG. 1, maximum length along the lateral direction Y) is longer than the lateral length L _{16a of the} lower end inner edge portion 16a.

  The urging unit urges the article 30 inserted through the through hole 24 and has a function of suppressing movement and rotation of the article 30. In the present embodiment, the upper portion of the first face sheet 22A and the second face sheet 22B, more specifically, the sheet upper portion 27 that is a portion located above the through hole 24, presses the article 30 from both sides in the front and back direction, (Hereinafter also referred to as the first urging unit). In addition, since the intermediate gusset sheet 20 is unfolded when the article 30 is accommodated, a force for urging the article 30 is applied to the first sheet 22A and the second sheet 22B, and each sheet strongly adheres to the surface of the article 30. .

  The intermediate gusset sheet 20 preferably has a tongue piece 25 at the edge of the through hole 24. The tongue piece 25 is a protruding portion that protrudes to the inside of the through hole 24. The first urging portion (sheet upper portion 27) abuts on the body portion 31 of the article 30 inserted through the through hole 24, and the tongue piece 25 further abuts against the surface of the body portion 31 and the urging portion. (Hereinafter, also referred to as a second urging unit). That is, in this embodiment, it has a 1st biasing part and a 2nd biasing part as a biasing part. The tongue piece may be formed so that only the tongue piece contacts the article. In this case, only the tongue piece becomes the biasing portion.

A plurality of tongue pieces 25 are preferably formed. The tongue piece 25 may be formed at any of the edge portions of the through hole 24, but is preferably formed at both lateral ends of the through hole 24. Each of the tongue pieces 25 formed at both lateral ends of the through hole 24 is located within a range of 40% or less, preferably 30% or less of the lateral length D ₂₄ from the lateral edge of the through hole 24, for example. To do. Further, the tongue piece 25 is preferably formed on each of the first face sheet 22A and the second face sheet 22B.

In the present embodiment, a total of four tongue pieces 25 are formed, for example, two on each of the first face sheet 22A and the second face sheet 22B. The tongue piece 25A formed on the first face sheet 22A and the tongue piece 25B formed on the second face sheet 22B are disposed to face each other in the front-back direction Z and preferably have substantially the same shape. The shape of the tongue piece 25 is not particularly limited, and has a substantially triangular shape in the present embodiment. The protruding length (maximum length from the root to the tip) of the tongue piece 25 is, for example, 40% or less of the lateral length D ₂₄ of the through-hole 24, and preferably 10 to 30% of the lateral length D ₂₄ . It is. In the present embodiment, the shape and dimensions of all the tongue pieces 25 are substantially the same, but the shape and the like of each tongue piece 25 may be different from each other.

  The tongue pieces 25A and 25B may be connected to each other (in this case, the crease line 21 is formed between the tongue piece 25A and the tongue piece 25B), but are preferably provided separately from each other. By separately providing each of the tongue pieces 25A and 25B separately, the tips of the tongue pieces 25A and 25B can be directed in the front and back direction Z. Therefore, the surface of the tongue piece 25 is in surface contact with the surface of the body portion 31. The body part 31 can be pressed firmly and the movement and rotation of the article 30 can be further suppressed (see FIG. 6). In order to provide them separately, a cut 26 may be formed on the extension line of the crease line 21 of the connected tongue pieces 25A and 25B. In the example shown in FIG. 1, the lower portions of the first face sheet 22 </ b> A and the second face sheet 22 </ b> B are each cut into a substantially L shape when viewed from the front to form a cut 26. That is, the two tongue pieces 25 </ b> A and 25 </ b> B are separated by the notch 26.

  The cut 26 may be formed by inserting a cut line (slit) on the crease line 21, but the first face sheet 22 </ b> A preferably includes a portion where the crease line 21 is formed in a state where the intermediate gusset sheet 20 is folded. And it forms by excising a part of 2nd surface sheet 22B. When the intermediate gusset sheet 20 is viewed from above (see FIG. 2), the cuts 26 are the edges of the tongue pieces 25A and 25B formed by the cuts 26 and the through holes 24 located between the tongue pieces 25A and 25B. It is preferable that the edge portion (lateral edge and the vicinity thereof) is formed by cutting the first face sheet 22A and the second face sheet 22B so as to exhibit a substantially U shape or a substantially trapezoidal shape. Thereby, for example, when the through hole 24 is greatly widened, the intermediate gusset sheet 20 is prevented from being broken along the crease line 21.

As shown in FIG. 3, the lateral length D ₂₄ of the through hole 24 is the lateral direction of the body portion 31 of the article 30 inserted through the through hole 24 from the viewpoint of compatibility between the insertability and the retainability of the article 30. longer than the diameter D _30. The lateral length D ₂₄ is, for example, 1.2 to 1.8 times, preferably 1.3 to 1.6 times the lateral diameter D ₃₀ . The distance L ₂₅ between the tongue pieces 25 formed on both sides in the lateral direction of the through hole 24 is preferably shorter than the lateral diameter D ₃₀ of the body portion 31. By setting the distance L ₂₅ <lateral direction diameter D ₃₀ , the tongue piece 25 can easily come into strong contact with the surface of the body portion 31. The interval L ₂₅ is, for example, 0.60 to 0.95 times, preferably 0.75 to 0.90 times the lateral diameter D ₃₀ .

Here, the transverse diameter D ₃₀ means the maximum diameter along the transverse direction Y of the portion that contacts the bottom surface portion 13 b of the article 30 when the article 30 is accommodated in the pouch container 10. In the present embodiment, since the body portion 31 has a substantially perfect circular shape, it is substantially the diameter of the trunk portion 31 synonymous (hereinafter, simply referred to as the diameter D _30). The interval L ₂₅ is the interval between the tongue pieces 25A and between the tongue pieces 25B, and means the interval between the closest parts (tips) of the tongue pieces.

The front and back direction length L ₂₄ (maximum length along the front and back direction Z) of the through hole 24 is preferably shorter than the diameter D ₃₀ of the body portion 31 of the article 30 inserted through the through hole 24. Since the intermediate gusset sheet 20 is bent in the front and back direction Z by the accommodation of the article 30 (see FIG. 5 described later), the article 31 can be inserted into the through hole 24 even if the length L ₂₄ <diameter D ₃₀ in the front and back direction. The front and back direction length L ₂₄ is, for example, 0.4 to 0.9 times the diameter D ₃₀ , and preferably 0.5 to 0.8 times. If the length L _{24 in the} front and back direction is within the above range, good retainability of the article 30 can be obtained without impairing the insertability of the article 30 into the through hole 24.

  As shown in FIG. 4, in the pouch container package 50 composed of the pouch container 10 and the article 30, the body portion 31 of the article 30 is inserted into the through hole 24 of the intermediate gusset sheet 20, and the bottom surface of the bottom gusset sheet 13. The article 30 is accommodated in a state where the body portion 31 is placed on the portion 13b. The article 30 accommodated in the pouch container 10 includes a substantially cylindrical body portion 31 and a lid portion 32 that closes an opening of the body portion 31. The body portion 31 is longer in the direction (vertical direction) in which the body portion 31 and the lid portion 32 are aligned than the radial direction, and the vertical length thereof is ½ or more of the vertical length of the pouch container 10. The lid portion 32 is smaller in diameter than the body portion 31 and shorter in the vertical direction. The article 30 is accommodated in the container so that the body portion 31 faces downward and the vertical direction is along the vertical direction of the pouch container 10.

  The article 30 is provided with a display unit 33 on which a product name, design, manufacturer name, product description, and the like are drawn. As described above, the display part 33 of the article 30 accommodated in the container is visible in the pouch container 10 through the transparent part 11a formed on the top sheet 11a. In the example shown in FIG. 4, a display portion 33 having a substantially rectangular shape in front view is provided on the body portion 31, and the entire display portion 33 is shown from the outside of the pouch container 10 through the transparent portion 11 a. The container 10 may have a configuration in which only a specific portion of the display unit 33 is visible from the outside.

As shown in FIGS. 4 and 5, the lateral length d ₂₄ of the through hole 24 when the article 30 is accommodated is slightly longer than the lateral diameter D ₃₀ of the body portion 31. When the intermediate gusset sheet 20 is unfolded by accommodating the article 30, the intermediate gusset sheet 20 is curved in the front-back direction Z, and thus the lateral length of the through hole 24 is reduced (that is, D ₂₄ > d ₂₄ ). The through hole 24 is preferably formed at a position that overlaps in the vertical direction X with a portion (hereinafter referred to as “flat portion f” (refer to FIG. 5B)) of the bottom surface portion 13 b that expands substantially flat. . As described above, the bottom surface portion 13b has a substantially flat range corresponding to the lower end inner edge portion 16a formed in a straight line, so the through hole 24 is formed at a position overlapping the lower end inner edge portion 16a in the vertical direction X in front view. It is preferred that

The horizontal length P _16a of the lower end inner edge portion 16a when the article 30 is accommodated is preferably 1.0 times (substantially the same) to 1.3 times the diameter D ₃₀ of the body portion 31, and the diameter D ₃₀ It is particularly preferable that they are substantially the same. That is, it is preferable that the horizontal length of the flat portion f of the bottom surface portion 13 b is substantially the same as the diameter D ₃₀ of the body portion 31. The portions of the bottom surface portion 13b located on both sides in the lateral direction of the body portion 31 are inclined upward corresponding to the oblique side inner edge portion 16b due to the development of the bottom gusset sheet 13, but the lateral length P _16a ≈ diameter D ₃₀ . Thereby, the trunk | drum 31 is pinched | interposed by the said inclination part of the bottom face part 13b, and it hold | suppresses from the horizontal direction both sides, and the lower part of the trunk | drum 31 is hold | maintained. Further, by forming the hypotenuse inner edge portion 16b in a straight line shape, the inclined portion of the bottom surface portion 13b can easily come into contact with the lower portion of the body portion 31, and the retainability is further improved.

In the pouch container 10, when the article 30 is accommodated, each wall sheet in the portion where the intermediate gusset sheet 20 is provided is gently curved along the surface of the trunk portion 31, and each wall sheet is interposed via the intermediate gusset sheet 20. In close contact with the surface of the body 31. On the other hand, the lower part of the pouch container 10 is in close contact with the surface of the body part 31 when the article 30 is accommodated, but the part corresponding to the range where the lower end inner edge part 16a is formed extends along the lateral direction. It is formed in a substantially linear shape. And each wall surface sheet | seat curves in the boundary part vicinity of the lower end inner edge part 16a and the hypotenuse inner edge part 16b. The lateral length of the lower end inner edge portion 16a is slightly reduced by accommodating the article 30, for example. The front and back direction length L _13b (maximum length along the front and back direction Z) of the flat part f can be set to be substantially the same as the diameter D ₃₀ of the body part 31 in order to bring each wall sheet into close contact with the body part 31. Is preferred.

  As shown in FIGS. 4 to 6, in the pouch container 10 having the above-described configuration, the urging portion of the intermediate gusset sheet 20 contacts the surface of the trunk portion 31 of the article 30 inserted through the through hole 24 of the sheet. The movement and rotation of the article 30 in the container are suppressed. In particular, the tongue piece 25 (second urging portion) strongly contacts the surface of the body portion 31 to press the body portion 31 and suppress the movement and rotation of the article 30. Further, the bottom surface portion 13b presses the lower portion of the body portion 31 from both sides in the lateral direction, and restrains the movement of the article 30 in the lateral direction. That is, the article 30 is stably held in the container by the bottom gusset sheet 13 and the intermediate gusset sheet 20. Moreover, the sheet | seat upper part 27 (1st biasing part) and each wall surface sheet of the intermediate | middle gusset sheet 20 closely_contact | adhere to the surface of the trunk | drum 31, and press the trunk | drum 31 from the front-back direction both sides. The movement of is restrained.

  Since the tongue pieces 25A and 25B formed at both lateral ends of the through hole 24 are separated by the notch 26, the tongue pieces 25A and 25B are bent along the surface of the body portion 31 as compared with the case where the tongue pieces 25A and 25B are connected. It is easy to increase the contact area with the body portion 31. As described above, the front ends of the tongue pieces 25A and 25B are individually directed in the front and back direction Z, the surface of the tongue piece 25 is in surface contact with the surface of the body part 31, and the body part 31 is pressed firmly, and each tongue piece 25 is pressed. A large frictional force acts between the surface of the body 31 and the body 31. Thereby, the movement of the article 30 in the container is restricted, and the rotation of the article 30 and the like are sufficiently suppressed. Since the intermediate gusset sheet 20 is expanded when the article 30 is accommodated and is removed when the article 30 is removed, a force for urging the article 30 is applied to the first sheet 22A and the second sheet 22B. Strongly adheres to the surface.

  As described above, according to the pouch container 10 having the above-described configuration, the intermediate gusset sheet 20 functions as a holding unit for the article 30, and the movement and rotation of the article 30 in the container are suppressed. Accordingly, the article 30 can be held at a predetermined position in the container. Further, even when a substantially cylindrical article 30 that is easy to rotate in the container is accommodated, it is possible to prevent the article 30 from rotating and a target portion (for example, a product name) of the display unit 33 from being invisible. Is possible.

Here, an example of a method for manufacturing the pouch container 10 will be described with reference to FIG.
FIG. 7 shows a process of forming each seal portion by laminating long sheets of sheet materials in the manufacturing process of the pouch container 10. The longitudinal direction of the long body is defined as “MD direction”, and the width direction is defined as “TD direction”.

  As shown in FIG. 7, first, long sheets (hereinafter, referred to as long bodies 11z, 12z, 13z, and 20z) of the top sheet 11, the back sheet 12, the bottom gusset sheet 13, and the intermediate gusset sheet 20 are prepared. And stacked on each other. Through holes 17z that become notches 17 are formed in the long body 13z, and through holes 24 are formed in the long body 20z at substantially equal intervals in the MD direction. In the step of laminating each long body, the long body 11z and the long body 12z are overlapped, and the long body 13z is inserted below the long body 11z and the long body 12z. The long body 20z is inserted between the central portions of the bodies 11z and 12z in the TD direction.

  In the long bodies stacked on each other, a side seal portion 14, a bottom seal portion 16, and a joint portion 23 are formed in a heat sealing process, and the long bodies 13z and 20z are developed on the inner surfaces of the long bodies 11z and 12z. Joined as possible. When forming the joining portion 23, the shielding plate is positioned between the intermediate gusset sheets 20, and heat sealing is performed so that the inner surfaces of the intermediate gusset sheets 20 are not joined in the front-back direction Z. Next, each long body is cut along the imaginary line X of the side seal portion 14 using, for example, a die cut roll or the like, and divided into individual container sizes. At this time, a notch 18 is formed in the side seal portion 14. In this way, the pouch container 10 shown in FIG. 1 is obtained. After the article 30 is accommodated in the container from the upper end opening of the pouch container 10, the upper seal part 15 and the hanging hole 19 are formed, whereby the pouch container package 50 shown in FIG. 4 is obtained. Note that the article 30 may be accommodated in an elongated state, and the upper seal portion 15 may be formed and then divided into individual container sizes.

  As described above, the pouch container 10 including the holding portion (intermediate gusset sheet 20) having a function of preventing movement and rotation of the article 30 is manufactured by a simple and highly productive process using the long body of each sheet material. be able to.
