Description

  The present invention relates to a pouch container, and more particularly to a pouch container filled with powder or granules (hereinafter referred to as powder or the like).

  In general, powdered milk, protein powder, and the like are sold in a state where they are filled in a metal can or pouch container. As illustrated in FIG. 21, a can 100 filled with a powder 40 such as powdered milk is provided with a scraping portion 101 for scraping off the powder 40 sown with a measuring spoon 41. The scraping portion 101 has a plate shape protruding in the radial direction of the can 100 so as to cover a part of the opening 102. Thereby, the quantity of the powder 40 per cup of the measuring spoon 41 can be made constant, and simple weighing becomes possible. In recent years, such a scraping function is also required for a pouch container filled with powder such as powdered milk.

  In view of such a situation, a pouch container having a fray bar has been proposed (see Patent Document 1). Patent Document 1 discloses a pouch container in which a foldable slidable bar is joined in a folded state below a chuck tape, and the slidable bar is opened linearly by opening the container.

JP 2003-155081 A

  By the way, when the powder is scraped off, the measuring spoon is pressed against the end of the scraping bar. If the angle formed by the end and the measuring spoon is too small or too large, the powder may not be scraped well. The fraying bar of Patent Document 1 has a problem that the end of the bar with which the measuring spoon can contact is oriented in the vertical direction of the container, so that the angle of the measuring spoon is greatly limited and is difficult to use. In addition, since the scraped bar is relatively thin, when a plastic sheet similar to the sheet material constituting the pouch container is used as the bar material, the lack of rigidity and easy bending also leads to poor operability. In addition, although the fixed part for suppressing bending is provided in this scraping bar, the bending operation of a fixed part is needed separately and is inconvenient.

The pouch container according to the present invention includes a sheet material constituting at least a front surface portion and a back surface portion, and a filling portion surrounded by the sheet material is filled with powder and the like, and a takeout portion for powder and the like is formed at the upper portion of the container. In the pouch container, in order to make it possible to measure the powder and the like with a measuring spoon, it is jointed so as to be deployable on the front surface portion and the back surface portion located below the take-out portion, and is provided along the container width direction. , comprises a gusset sheet covering a part of the filling unit, the container end portion in the width direction of the gusset sheet, characterized in that it is a scraping unit which enables scraping metering of powder or the like.

  According to the said structure, the powder etc. which were scooped with the measuring spoon can be scraped off using the gusset sheet developed at the time of opening of the taking-out part. When scraping off powder, etc., the measuring spoon is pressed against the end of the gusset sheet in the width direction. The end faces the width direction of the container, so that the end and the measuring spoon inserted from the take-out section form. It is easy to adjust the angle to an angle suitable for fraying (for example, 90 ° ± 45 °), and the same usability as a frayed portion provided on a metal can can be obtained.

In the pouch container according to the present invention, side seal portions for joining the front surface portion and the back surface portion are provided at both end portions in the container width direction, and the gusset sheet has one side seal portion at one end in the width direction. It is preferable to be joined to the part.
According to the said structure, since the one end part of the width direction of a gusset sheet | seat is fixed by a side seal part, a gusset sheet | seat becomes difficult to bend at the time of scraping, and operativity further improves. In this case, the measuring spoon is pressed against the other end in the width direction of the gusset sheet.

Moreover, in the structure which fixed the width direction one end part of the gusset sheet | seat, a gusset sheet | seat can be made into the upward gusset sheet folded up toward the upper part.
According to this configuration, when the gusset sheet is unfolded, the upper surface of the gusset sheet forms a slope with the other end in the width direction on which the measuring spoon can come into contact with the lower side. The body and the like can easily slide down into the filling portion naturally, and the upper surface of the gusset sheet can be kept hygienic. In addition, the angle formed by the end portion and the measuring spoon inserted from the take-out portion can be easily adjusted to a more suitable angle (for example, around 90 °).

Moreover, in the structure which fixed the width direction one end part of the gusset sheet | seat, a gusset sheet | seat can be made into the downward facing gusset sheet | seat folded down toward the downward direction.
According to this configuration, when the gusset sheet is unfolded, the upper surface of the gusset sheet forms a slope with the other end in the width direction positioned above, so the other end in the width direction is formed closer to the take-out portion. Therefore, it becomes easier to operate the measuring spoon.

Moreover, it is preferable that the pouch container according to the present invention is provided with a recovery unit for returning powder or the like present on the gusset sheet to the filling unit.
According to the said structure, when powder etc. accumulate on a gusset sheet | seat, the powder etc. can be returned from a collection | recovery part to a filling part, and a gusset sheet | seat upper surface can be kept hygienic.

  According to the pouch container according to the present invention, a satisfactory fraying operation can be performed. In particular, by joining one end portion in the width direction of the gusset sheet to the front surface portion and the back surface portion with one side seal portion, the bending of the gusset sheet is greatly suppressed, and the operability is further improved.

  In this specification, the term “extracting portion” is not limited to an opening that allows communication between the outside of the container and the filling portion that is the inner space of the container, but the opening is formed by cutting the sheet material or the like. It is intended to include a portion (that is, an opening formation scheduled portion). In the embodiment, the former will be referred to as the takeout port 18 and the latter will be referred to as the takeout port formation scheduled portion 18z.

  In the embodiment, “powder or granules” filled in a pouch container will be described as a powder 40 intended for powdered milk, protein powder, and the like. However, the “powder or granule” is not particularly limited as long as it can be scraped off with the measuring spoon 41, and seasonings such as sugar and salt, flour, or coffee having a larger particle size. Beans and tea leaves are also included.

  In the embodiment, the portion where the take-out port 18 is provided is the “upper portion” of the container, and the portion facing the upper portion is the “lower” portion of the container. Further, the direction in which the sheet materials are laminated is defined as the “front and back direction” of the container, and the direction perpendicular to the vertical direction and the front and back direction is defined as the “width direction or left and right direction” of the container. Hereinafter, the vertical direction, the front / back direction, and the width direction may be simply referred to.

<First Embodiment>
With reference to FIGS. 1-6, the structure of the pouch container 10 which is 1st Embodiment is demonstrated.
FIG. 1 shows the pouch container 10 before the powder 40 is filled, and FIG. 3 shows the pouch container 10 filled with the powder 40. 2 and 4 show cross sections obtained by cutting the upward gusset sheet 30 and the vicinity thereof in the vertical direction in the pouch container 10 shown in FIGS. 1 and 3, respectively. FIG. 5 is a perspective view of the pouch container 10 and shows a state where the takeout port 18 is opened. FIG. 6 is a view of the upward gusset sheet 30 shown in FIG. 5 as viewed from the upper right side. In FIG. 5, the chuck 16 is omitted and only a part of the seal portions are hatched for the sake of clarity.

  The pouch container 10 includes a top sheet 11, a back sheet 12, and a bottom gusset sheet 13, and is a standing pouch that can stand by filling contents. The top sheet 11 and the back sheet 12 are sheet materials that respectively constitute the front surface part and the back surface part of the container, and the bottom gusset sheet 13 is inserted by being folded between the front surface part and the back surface part. It is the sheet | seat material which comprises the bottom gusset part developed by filling. The bottom gusset sheet 13 is mountain-folded upward (see FIG. 1).

  The pouch container 10 forms a seal portion between the top sheet 11 and the back sheet 12 that are overlapped with each other, with the bottom gusset sheet 13 being inserted from the bottom end of the container, and joining the edges of each sheet material. It is the structure which sealed the container interior space enclosed with the sheet | seat material. This container internal space becomes the filling portion 15 filled with the powder 40. Each of the top sheet 11 and the back sheet 12 has a substantially rectangular shape extending slightly longer in the vertical direction. The bottom gusset sheet 13 also has a substantially rectangular shape, and is provided, for example, in a range of about ¼ from the lower ends of the top sheet 11 and the back sheet 12.

  Further, the pouch container 10 includes an upward gusset sheet 30 as a scraping portion that enables scraping and weighing of the powder 40 by the measuring spoon 41. The upward gusset sheet 30 is a gusset sheet that is joined to the front surface portion and the back surface portion so as to be expandable and covers a part of the filling portion 15 along the width direction, and like the bottom gusset sheet 13, The mountain is folded upward (see FIGS. 1 and 2). In the present embodiment, the powder 40 is filled in a range that does not cover the upward gusset sheet 30 (see FIG. 3). Hereinafter, the portion below the upward gusset sheet 30 is referred to as a filling portion 15.

  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. Moreover, since the said seal part is normally formed by heat sealing, heat sealing property is also requested | required of a sheet material. As the sheet material, a multilayer sheet material having a base film layer and a sealant layer that imparts heat sealability is suitable, and when high gas barrier properties are required, the sheet material is provided between the base film layer and the sealant layer. It is preferable to provide a gas barrier layer.

  Here, constituent materials of the base film layer, the sealant layer, and the gas barrier layer are exemplified. In addition, lamination | stacking of these each layer can be performed by the conventional lamination method, for example, the dry lamination by an adhesive agent, the heat lamination which adhere | attaches with a heat | fever by pinching | interposing a heat bonding layer.

  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 having one layer or two or more layers composed of ether sulfone (PES) and ethylene-vinyl alcohol copolymer (EVOH) can be exemplified.

  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 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 sheet material can be provided with a printed layer (not shown) for displaying the product name of the contents, the product description such as raw materials and precautions for use, and other various designs. For example, the printing layer can be formed on the inner surface of the base film layer by a known method such as gravure printing.

  The seal portion is preferably formed by heat sealing. The seal part by heat sealing can be formed by superposing and thermocompression bonding so that the sealant layer of each sheet material is inside the container.

  The pouch container 10 includes an upper edge seal portion 20 (see FIG. 3), a lower edge seal portion 21, and a side seal portion 22 as the seal portion. The upper edge seal part 20 is a seal part formed after the powder 40 is filled, and is formed by joining the upper edges of the top sheet 11 and the back sheet 12. The lower edge seal portion 21 is a seal portion formed at the edge of the bottom gusset sheet 13 and is formed by joining the bottom gusset sheet 13 to the top sheet 11 and the back sheet 12. Further, the bottom gusset sheet 13 is formed with notches 14 at both ends in the width direction, and the top sheet 11 and the back sheet 12 are directly joined through the notches 14. The side seal part 22 is formed by directly joining the top sheet 11 and the back sheet 12 at both ends in the container width direction.

  When the pouch container 10 is filled with the powder 40, the top sheet 11 and the back sheet 12 are separated from each other, the bottom gusset sheet 13 is developed, and in particular, the bottom of the container is swollen. Thus, the self-supporting property of the pouch container 10 is expressed. Note that the upward gusset sheet 30 is also usually slightly expanded (see FIGS. 3 and 4). For example, the powder 40 is filled from the upper end of the container, and the filling portion 15 is sealed by forming the upper edge seal portion 20 after filling.

  Further, the pouch container 10 is provided with a chuck 16 and a notch 17 in the vicinity of the upper edge seal portion 20. The chuck 16 is provided above the upward gusset sheet 30, and the notch 17 is provided above the chuck 16.

  The chuck 16 is configured by, for example, opposingly arranging a first sheet with a ridge and a second sheet with a ridge that fits into the ridge. For example, the first sheet is bonded to the inner surface of the top sheet 11, and the second sheet is bonded to the inner surface of the back sheet 12.

  The notch 17 is a notch serving as a cutting starting point for cutting and opening the top sheet 11 and the back sheet 12, and can be provided in each of the left and right side seal portions 22. When the sheet material is cut along the width direction from the notch 17, the upper edge seal portion 20 is removed, and a takeout port 18 (see FIG. 5) that connects the outside of the container and the filling portion 15 is formed. A two-dot chain line extending from the notch 17 in FIGS. 1 and 3 indicates a take-out port formation scheduled portion 18z that is cut at the time of opening and becomes the take-out port 18. Hereinafter, cutting the sheet material to form the take-out port 18 in the take-out port formation scheduled portion 18z is referred to as opening. After opening, the takeout port 18 can be opened and closed by the chuck 16.

  Hereinafter, the components of the pouch container 10, particularly the configuration of the upward gusset sheet 30, will be described in further detail.

  The upward gusset sheet 30 is a gusset sheet in which a fold line 31 is formed. The upward gusset sheet 30 is folded when the take-out port 18 is closed, and expands when the take-out port 18 is opened by opening the chuck 16 and exhibits a scraping function. In the present embodiment, a crease line 31 is provided at the upper end of the upward gusset sheet 30 along the width direction. In addition, the part (henceforth front side half part 30a) located in the surface sheet 11 side from the crease line 31, and the part (henceforth back side half part 30b) located in the back surface sheet 12 side from the crease line 31. It is preferable that the vertical lengths are substantially equal.

  The upward gusset sheet 30 is provided below the take-out port formation scheduled portion 18z. Further, the upward gusset sheet 30 is provided below the chuck 16. It is preferable that the chuck 16 and the upward gusset sheet 30 are both provided substantially parallel to each other along the container width direction. In the present embodiment, the chuck 16 and a part of the upward gusset sheet 30 (a joining portion 33 described later) are provided over the entire width of the pouch container 10. Further, the upward gusset sheet 30 is preferably provided in the vicinity of the chuck 16 as long as it does not contact the chuck 16 from the viewpoint of increasing the capacity of the filling portion 15. The interval between the lower end of the chuck 16 and the crease line 31 is preferably about 0.5 mm to 10 mm, for example.

  The upward gusset sheet 30 is provided so as to cover a part of the filling portion 15. The width direction length W2 of the main body portion 32 that covers the filling portion 15 is about 10% to 70% of the width direction length W1 of the pouch container 10 from the viewpoints of fraying property, take-out property of the powder 40, and the like. Is preferable, about 20% to 60% of W1 is more preferable, and about 30% to 50% of W1 is particularly preferable. In the pouch container 10, the powder 40 in the filling portion 15 can be taken out from an opening (a portion where a cut portion 37 described later) is formed in the upward gusset sheet 30 where the main body portion 32 does not exist.

  The upward gusset sheet 30 may be individually provided with a length of W2, but in this embodiment, from the viewpoint of productivity, as will be described later, a portion to be joined to each of the front and back sheets remains. It is preferable to use the elongated body 30z of the upward gusset sheet 30 having the cut portion 37 partially cut away (see FIG. 7). For this reason, the upward gusset sheet 30 includes a main body portion 32 that is mountain-folded upward and a line-shaped (band-shaped) connecting portion 38 that extends from the main body portion 32.

  The upward gusset sheet 30 is joined to the inner surface of the top sheet 11 and the inner surface of the back sheet 12 positioned below the chuck 16, respectively. Specifically, the lower end portion of the front half portion 30a is heat sealed to the top sheet 11, and the lower end portion of the back half portion 30b is heat sealed to the back sheet 12 to form two line-shaped joint portions 33. The

  Further, in the upward gusset sheet 30, the joining portion 33 is formed on substantially the entire connecting portion 38 extending from the front half portion 30 a and the back half portion 30 b. Thereby, the joint part 33 is formed substantially parallel to the chuck 16 over the entire width of the pouch container 10, and the width of the joint part 33 is preferably about 1 to 10 mm, for example. In addition, the width (length in the vertical direction) of the connecting portion 38 can be made larger than the width of the joint portion 33 (see a modification example to be described later). -20 times, preferably 1.5-10 times. By increasing the width of the connecting portion 38, the rigidity of the connecting portion 38 can be increased, and the transportability of the long body 30z during manufacturing can be improved.

  In the present embodiment, a takeout port 18 (a takeout port formation scheduled portion 18z) is provided across the entire width of the pouch container 10 including just above the upward gusset sheet 30. On the other hand, the take-out port 18 may be provided in a part thereof along the container width direction. However, in this case, it is preferable to form the take-out port 18 at least at a position shifted from directly above the upward gusset sheet 30 from the viewpoint of fraying properties and the like. That is, the take-out port 18 is formed at least on the filling portion 15 that is not covered by the upward gusset sheet 30.

  Further, the upward gusset sheet 30 is secured to the topsheet 11 and the backsheet 12 by one side seal portion 22 at one end in the width direction from the viewpoint of improving the frayability by ensuring the rigid stability of the gusset sheet 30. It is preferable to be joined. The one end portion in the width direction is the first end portion 34 of the main body portion 32, and the whole is fixed by the side seal portion 22. And the 2nd end part 35 which is the width direction other end part of the main-body part 32 is utilized for abrasion. That is, the measuring spoon 41 is pressed against the second end portion 35.

  According to the joining form, the main body 32 of the upward gusset sheet 30 is unfolded on the second end 35 side until the front half 30a and the back half 30b are substantially parallel (see FIGS. 5 and 6). . In the main body portion 32 that is largely developed, an upper surface 36 having a substantially triangular shape is formed. The triangle on the upper surface 36 is an inclined isosceles triangle with the apex P1 in contact with the side seal portion 22 as the upper end and the apexes P2 and P3 in contact with the joint portion 33 as the lower end, and the second end 35 is the lower side. As described above, the developed main body 32 is stably supported by the portions corresponding to the vertices P1 to P3 of the upper surface 36.

Next, an example of a method for manufacturing the pouch container 10 having the above configuration will be described with reference to FIG.
FIG. 7 schematically shows a process of laminating long sheets of each sheet material and forming each seal portion in the manufacturing process of the pouch container 10. Here, let the longitudinal direction of a long body be MD direction, and let the width direction of a long body be TD direction.

  As shown in FIG. 7, first, a sheet constituting the top sheet 11, the back sheet 12, the bottom gusset sheet 13, and the chuck 16 (for example, a first sheet with a ridge and a second sheet with a ridge) ) And long bodies of the upward gusset sheet 30 (hereinafter, referred to as long bodies 11z, 12z, 13z, 16z, and 30z) are prepared and stacked on each other. The long bodies 13z and 30z are both mountain-folded toward one end side along the MD direction before lamination. Further, a cut portion 37 is formed on the long body 30z by leaving a connecting portion 38 by a die cut roll or the like, and a plurality of main body portions 32 are formed by the connecting portion 38 (a portion where all or a part thereof becomes the joint portion 33). Processed into a connected shape. The long body 16z is laminated in a state in which the ridges of the first sheet and the ridges of the second sheet are fitted.

  In addition, the size of the cut portion 37 of the long body 30z can be reduced, and for example, the cut portion 37 can be formed into a substantially V-shaped cut or the like when viewed from the front. In this case, the rigidity of the long body 30z is increased and the transportability is improved. However, since the opening through which the powder 40 can be taken out becomes small, for example, a cut line continuous with the cut portion 37 is provided on the gusset sheet 30. It may be formed in the part so that the opening can be enlarged.

  In the laminating process of each long body, first, the long body 11z and the long body 12z are overlapped, and the long body 13z is inserted into the lower ends of the long body 11z and the long body 12z. The long bodies 16z and 30z are inserted into the upper part of the long body 12z, respectively. At this time, the long body 30z is inserted on the lower end side of the long body 16z. Note that a notch 17 and the like are formed in a later step in a portion on the upper end side of the long body 16z.

  Each sealing part is formed in the elongate body which passed through the lamination process at the heat sealing process. In the heat sealing step, the predetermined portion is heat sealed along the lower edge of the long body and the TD direction. Here, the lower edge of the elongated body is a portion that becomes the lower edge of the pouch container 10, and the predetermined portion is a portion that becomes a side edge of the pouch container 10. That is, by this heat sealing process, the lower edge seal portion 21 and the side seal portion 22 (wide seal portions for two containers) are formed.

  In the heat sealing step, the long bodies 16z and 30z are further joined to the long body 11z and the long body 12z, respectively. A joining portion 33 along the MD direction is formed at the lower end of the long body 30z. Further, the side seal portion 22 is formed in a state in which the first end portion 34 of the main body portion 32 is disposed at a portion that becomes a side edge of the pouch container 10. As a result, the first end 34 is fixed to the top sheet 11 and the back sheet 12.

  Then, the said elongate body is cut along the virtual line X of the side seal part 22, for example using a die cut roll etc., and it divides | segments into each container size. At this time, the notch 17 can be formed in the side seal portion 22. In this way, the pouch container 10 shown in FIG. 1 is obtained. Then, after the powder 40 is filled from the upper end of the container, the upper edge seal portion 20 is formed, whereby the pouch container 10 filled with the powder 40 shown in FIG. 3 is obtained.

Next, with reference to FIG. 8 and FIG. 9, the action and effect of the pouch container 10 having the above configuration will be described in detail while exemplifying a state in which the powder 40 is scraped off using the upward gusset sheet 30. 5 and 6 will be referred to as appropriate.
FIG. 8 is a front view of the pouch container 10, and FIG. 9 is a top view of the pouch container 10, both of which show how the powder 40 is scraped off.

  As shown in FIG. 5 and the like, when the powder 40 is taken out from the filling portion 15, the takeout port 18 is formed by using the notch 17 and then the chuck 16 is opened to open the takeout port 18. Then, by opening the take-out port 18 widely, the top sheet 11 and the back sheet 12 are separated from each other in the upper part of the container, and the upward gusset sheet 30 is developed. Although the first end 34 of the main body 32 is not expanded, on the second end 35 side, for example, a front half 30a joined to the top sheet 11 and a back half 30b joined to the back sheet 12 are provided. It develops so that it may become a plate shape substantially parallel mutually. An inclined substantially triangular upper surface 36 is formed with the apex P1 in contact with the side seal portion 22 as the upper end and the apexes P2 and P3 in contact with the joint portion 33 as the lower ends (see FIG. 6).

  When the main body portion 32 of the upward gusset sheet 30 is unfolded, as shown in FIGS. 8 and 9, the dish portion of the measuring spoon 41 with the powder 40 can be pressed against the second end portion 35 of the main body portion 32. . The excess powder 40 can be scraped off by pulling the measuring spoon 41 upward while pressing the dish portion against the second end portion 35. Thus, the amount of the powder 40 per cup of the measuring spoon 41 can be made constant, and simple weighing can be performed.

  In the pouch container 10, the first end portion 34 of the main body portion 32 is fixed by the side seal portion 22, and the deployed main body portion 32 is stably supported at portions corresponding to the apexes P <b> 1 to P <b> 3 of the upper surface 36. When the measuring spoon 41 is pressed against the main body 32, it is difficult for the main body 32 to bend, and the operability is further improved. Furthermore, since the upper surface 36 of the main body 32 is a substantially triangular slope with the second end portion 35 positioned below, the powder 40 remaining on the upper surface 36 after scraping naturally slides into the filling portion 15, The upper surface 36 can be kept hygienic.

  Further, in the pouch container 10, as described above, the second end portion 35 used for scraping faces slightly downward from the container width direction, so that the spilled powder 40 does not spill out of the dish portion, It is easy to adjust the angle formed between the two end portions 35 and the measuring spoon 41 inserted from the take-out port 18 to an angle that is easily worn, for example, around 90 °.

  That is, according to the pouch container 10, it is possible to provide a scraping portion that enables a favorable scraping operation in a foldable and flexible container.

<Second Embodiment>
With reference to FIGS. 10-13, the structure of the pouch container 50 which is 2nd Embodiment is demonstrated. Here, the same components as those in the first embodiment are denoted by the same reference numerals, and redundant description is omitted.
FIG. 10 shows the pouch container 50 before the powder 40 is filled. FIG. 11 shows a cross-section of the pouch container 50 shown in FIG. FIG. 12 is a perspective view of the pouch container 50 and shows a state where the takeout port 18 is opened. FIG. 13 is a view of the downward gusset sheet 60 shown in FIG. 12 as viewed from the upper right side. In FIG. 12, for the sake of clarity, the chuck 16 is omitted, and only some of the seal portions are hatched.

  The pouch container 50 includes a downward gusset sheet 60 as a scraping portion. Similarly to the upward gusset sheet 30, the downward gusset sheet 60 is a gusset sheet that is joined to the front surface portion and the back surface portion so as to be unfoldable and covers a part of the filling portion 15 along the width direction. The mountain is folded downward (see FIGS. 10 and 11). In addition, since the downward gusset sheet 60 shown in this embodiment is also provided by a long body having a cut portion in the same manner as the first embodiment (upward gusset sheet 30), the main body portion is folded in a downward direction. 62 and a line-shaped (band-shaped) connecting portion 68 extending from the main body portion 62. The joint 63 is formed substantially parallel to the chuck 16 over the entire width of the pouch container 10. Further, the powder 40 is filled in a range that does not cover the downward gusset sheet 60 (see FIG. 12). Hereinafter, the portion below the downward gusset sheet 60 is referred to as a filling portion 15.

  In the downward gusset sheet 60, a crease line 61 is formed at the lower end along the width direction. In addition, the arrangement and size of the downward gusset sheet 60 (the front half 60a, the back half 60b, the main body 62, etc.) are the same as those of the upward gusset sheet 30. Further, the first end portion 64 of the main body portion 62 is joined to the topsheet 11 and the backsheet 12 by one side seal portion 22, and the second end portion 65 is used for scraping. Also in this embodiment, the takeout port 18 (takeout port formation scheduled portion 18z) is provided over the entire width of the pouch container 50 including the portion directly above the downward gusset sheet 60.

  The downward gusset sheet 60 preferably has a powder recovery unit 70. The powder recovery unit 70 is a through-hole formed in a portion of the main body 62 that extends along the fold line 61 and has a function of returning the powder 40 existing on the downward gusset sheet 60 to the filling unit 15. It is particularly preferable that the powder recovery unit 70 is formed on the first end 64 side of the main body 62 and in a portion in contact with the one side seal portion 22. In the present embodiment, the powder is cut in a straight line when viewed from the front over the crease line 61 (for example, the crease line 61 located in the vicinity of the side seal portion 22) from the intermediate portion in the vertical direction of the first end portion 64. A collection unit 70 is formed. In addition, the hole shape, hole size, number, and the like of the powder recovery unit 70 are not limited to the illustrated shape, and can be set as appropriate according to the particle size of the powder 40 and the like.

  The main body portion 62 of the downward gusset sheet 60 is unfolded on the second end 65 side until the front half portion 60a and the back half portion 60b are substantially parallel (see FIGS. 12 and 13). In the main body portion 62 that is largely developed, an upper surface 66 having a substantially triangular shape is formed. The triangle on the upper surface 66 is an isosceles triangle that is inclined with the virtual vertex P4 in contact with the side seal portion 22 being the lower end and the vertexes P5 and P6 in contact with the joining portion 63 being the upper end when the powder recovery unit 70 is not present, The second end portion 65 is the upper side. The developed main body 62 is stably supported in the vicinity of the vertices P4 to P6 of the upper surface 66.

Next, with reference to FIG. 14 and FIG. 15, the action and effect of the pouch container 50 having the above-described configuration will be described in detail while exemplifying a state in which the powder 40 is scraped off using the downward gusset sheet 60. Note that FIG. 12 and FIG. 13 are referred to as appropriate.
FIG. 14 is a front view of the pouch container 50, and FIG. 15 is a top view of the pouch container 50.

  As shown in FIG. 12 and the like, the downward gusset sheet 60 is unfolded by opening the extraction port 18 to a large extent. On the second end 65 side of the main body 62, for example, the front half 60a joined to the top sheet 11 and the back half 60b joined to the back sheet 12 have a substantially parallel plate shape. expand. Then, an inclined substantially triangular upper surface 66 is formed having a virtual vertex P4 in contact with the side seal portion 22 as a lower end and apexes P5 and P6 in contact with the joint portion 63 as upper ends (see FIG. 13). When the main body 62 is deployed, as shown in FIGS. 14 and 15, the dish portion of the measuring spoon 41 in which the powder 40 is placed can be pressed against the second end 65 of the main body 62. In the pouch container 50 as well, excess powder 40 can be scraped off by pulling the measuring spoon 41 upward while pressing the dish portion against the second end portion 65.

  In the pouch container 50, the second end portion 65 used for scraping faces slightly upward from the container width direction, and the second end portion 65 is positioned above the container as compared with the upward gusset sheet 30. For this reason, since the distance between the second end portion 65 and the take-out port 18 is reduced, it becomes easier to operate the measuring spoon 41. For example, even if the operation width of the measuring spoon 41 is widened, it is difficult for the measuring spoon 41 to be caught on the end of the container and the like, and good operability can be obtained.

  Further, in the pouch container 50, the first end portion 64 of the main body portion 62 is fixed by the side seal portion 22, and the deployed main body portion 62 is stably supported in the vicinity of the vertices P4 to P6 of the upper surface 66. When the measuring spoon 41 is pressed against the main body 62, it is difficult to bend, and the operability is further improved. Furthermore, since the upper surface 66 of the main body 62 is a substantially triangular slope with the second end 65 positioned above, the powder 40 tends to accumulate on the upper surface 66 due to abrasion, but the powder is collected in the powder recovery unit. The filling unit 15 can be returned from 70. For this reason, as in the case of the upward gusset sheet 30, the upper surface 66 can be kept hygienic.

The above embodiment can be appropriately changed in design without departing from the object of the present invention.
For example, in the above embodiments, a standing pouch has been exemplified, but the configuration of the present invention may be applied to other pouch configurations such as a flat pouch that does not have self-supporting properties.

  Moreover, in the said 1st Embodiment, although the 1st end part 34 of the main-body part 32 illustrated the form joined to the surface part and the back surface part by the side seal part 22, FIG. 16 (In the front view of the pouch container 10f. As shown in the figure showing a form before filling with the powder 40, the main body part 32f of the upward gusset sheet 30f may be provided in the central part in the container width direction. In the pouch container 10f illustrated in FIG. 16, both end portions (first end portion 34f, second end portion 35f) in the width direction of the main body portion 32f are separated from the side seal portion 22. Then, the powder 40 can be scraped off by pressing the measuring spoon 41 against either the first end portion 34f or the second end portion 35f.

  Moreover, in the said 1st Embodiment, although the form which has the one main-body part 32 was illustrated, it shows in FIG. 17 (The figure which shows the form before being filled with the powder 40 which is a front view of the pouch container 10g). Thus, it is good also as a form which has several main-body parts 32g. A pouch container 10g illustrated in FIG. 17 is obtained, for example, by forming the left and right side seal parts 22 in a state where the intermediate part of the main body part 32g is arranged at the part that becomes the left and right side edges of the container.

FIG. 18A to FIG. 20 further show a modification of the first embodiment.
(A) of each figure is a front view of each pouch container and shows a form before filling with powder 40, and (b) of each figure is a top view of each pouch container and is taken out. It is a figure which shows the state which opened the opening | mouth 18.

  In the pouch container 10u illustrated in FIG. 18A, a powder recovery unit 45u is provided between the top sheet 11, the back sheet 12, and the upward gusset sheet 30u. Similar to the powder recovery unit 70, the powder recovery unit 45 u has a function of returning the powder 40 existing on the upward gusset sheet 30 u to the filling unit 15. The powder recovery part 45u is provided by not forming the joining part 33u in a part of the lower end part of the main body part 32u. In the pouch container 10u, the joint portion 33u is formed only at the lower end portion located in the vicinity of the second end portion 35u of the main body portion 32u. In the other portions, the front and back sheets and the main body portion 32u are not joined, and an opening (gap) that can drop the powder 40 into the filling portion 15 between the front and back surface sheets and the main body portion 32u. A powder recovery unit 45u is provided.

  In the pouch container 10, since the lower end portion is joined to the front and back sheets over the entire width of the main body portion 32, the powder 40 easily collects between the main body portion 32 and the front and back sheets. For example, this problem can be improved by providing the powder recovery unit 45u. Thereby, the pouch container 10u is, for example, a container with good appearance and improved hygiene of the upward gusset sheet 30u.

  Further, in the pouch container 10u, the joining portion 33u is not formed on substantially the entire connecting portion 38u, but the joining portion 33u is formed leaving the upper end portion and the lower end portion of the connecting portion 38u. That is, the width of the connecting portion 38u is larger than the width of the joint portion 33u. According to this aspect, as described above, the transportability of the long gusset sheet can be improved during manufacturing, and heat sealing when forming the joint portion 33u is facilitated.

  As shown in FIG. 18B, the lower end portion of the main body portion 32u may be cut leaving only the vicinity of the second end portion 35u within a range that does not impair the transportability of the long gusset sheet. According to this form, the hole size of the powder recovery part 45u can be enlarged. Such a cut shape is not limited to the L shape seen from the front illustrated in FIG. 18B, and various shapes such as a U shape and a straight shape similar to the case of the powder recovery unit 70 can be applied.

  A pouch container 10v illustrated in FIG. 19 has two main body parts 32v connected by a connecting part 38v, similarly to the pouch container 10g. The main body portions 32v provided on both sides in the width direction of the pouch container 10v have substantially the same shape and size. In the pouch container 10v, the powder 40 can be satisfactorily scraped by the second end portion 35v of any main body portion 32v.

  The pouch container 10v is provided with a powder recovery unit 45v having the same form as the powder recovery unit 45u of the pouch container 10u. Further, the pouch container 10v is provided with a powder recovery unit 46v by cutting a portion corresponding to the crease line 31v. The powder recovery part 46v is formed by cutting the first end part 34v from the first end part 34v into a straight line when viewed from the front. In addition, the width of the connecting portion 38v is larger than the width of the joint portion 33v, like the pouch container 10u.

  The pouch container 10w illustrated in FIG. 20 has a form in which a powder recovery part 47w is further provided between two main body parts 32v of the pouch container 10v. In the pouch container 10w, the joining portion 33w is formed only at the lower end portion located in the vicinity of the second end portion 35v of each main body portion 32v, and the joining portion 33w is not formed at the connecting portion 38. Thereby, the powder collection | recovery part 47w is provided between the connection part 38 which connects each main-body part 32v, and the front and back sheet | seat.

  In the pouch containers 10u, 10v, since the connecting portions 38u, 38v are joined to the front and back sheets, the powder 40 is between the connecting portions 38u, 38v (portions located above the joined portions) and the front and back sheets. Although it is easy to accumulate, according to the pouch container 10w, this problem can be improved. As a result, the pouch container 10u is further improved in appearance, and the sanitary aspect of the upward gusset sheet 30u is further improved.
