Modes for Carrying Out the Invention

[0015] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the drawings. <First Embodiment> Figure 1 is a front view showing a pouch with a spout according to the first embodiment of the present disclosure. Figure 2 is a detailed view of Figure 1. Figure 3 is a cross-sectional view along line AA in Figure 2, showing a cross-section of the embossed portion 11. The rear view is omitted because it is basically symmetrical to the front view shown in Figure 1. The pouch with a spout of the present disclosure has a structure in which a spout portion 3 is attached to a pouch body portion 1 which has a storage portion 10. After removing the cap 3a from the spout portion 3, the contents stored in the storage portion 10 can be poured out through the spout portion 3. There are no particular limitations on the contents, but liquids such as fluids are particularly suitable.

[0016] The pouch with a spout in this embodiment includes a spout section 3, which is a plastic molded body, and a main body section 1, which is made of film. The spout section 3 is attached to the upper corner of the main body section 1. As shown in Figure 1, the planar shape of the main body section 1 is a roughly hexagonal shape obtained by cutting off two upper corners from a rectangular shape. The spout section 3 is equipped with a mounting section 3b and is attached to the main body section 1 via the mounting section 3b. Although not shown in the figure, screw threads are formed on the outer surface of the spout section 3 so that it can be screwed into the cap 3a. The spout section 3 is molded from plastic separately from the main body section 1. The spout section 3 is joined to the film that makes up the main body section 1 by sandwiching the mounting section 3b between them. In this disclosure, the term "pouch with a spout" is a concept that includes not only pouches with spouts that are not filled with contents, but also pouches with spouts that are filled with contents.

[0017] (Main body) The main body 1 forms the storage section 10 and is primarily for storing contents. The main body 1 is composed of three surfaces. In this embodiment, the three surfaces—the front surface, the back surface, and the bottom surface—are realized by the front surface film 17, the back surface film 18, and the bottom surface film 19, respectively.

[0018] As shown in Figure 1, the main body 1 has a roughly hexagonal shape when viewed from the front, and has an upper edge 31, a lower edge 32 opposite the upper edge 31, a first side edge 33 and a second side edge 34 extending in the direction connecting the upper edge 31 and the lower edge 32, a mounting edge 35 extending between the upper edge 31 and the first side edge 33, and an upper side edge 36 extending between the upper edge 31 and the second side edge 34. The roughly hexagonal shape is a concept that includes not only hexagons with six sharp corners, but also those where each corner is chamfered, resulting in an outwardly convex arc shape.

[0019] The main body 1 has a shape in which two roughly triangular sections are cut out from a rectangular film when viewed from the front. Of these, the corners that are extensions of the upper edge 31 and the second side edge 34 are cut out along the upper side edge 36. In this embodiment, the upper side edge 36 is straight. The upper side edge 36 may also be a curved shape that is recessed toward the storage section 10 in the main body 1. Because the upper side edge 36 is either straight or a curved shape that is recessed toward the storage section in the main body, it becomes possible to grasp a position close to the center of the storage section 10 from the side of the upper side edge 36, making it easy to grasp the pouch by hand and pour the contents to the desired location, even when heavy contents are stored inside.

[0020] As shown in Figure 1, the main body 1 includes a side edge sealing section 5, a bottom sealing section 6, and a mounting edge sealing section 7. The upper edge 31 side is unsealed and forms an opening 15. The side edge sealing section 5 consists of a first side edge sealing section 5a and a second side edge sealing section 5b. The bottom sealing section 6 is divided into a first bottom sealing section and a second bottom sealing section. After the contents are filled into the pouch with a spout through the opening 15, the upper edge sealing section located on the upper edge 31 is sealed by heat sealing or the like after the contents are filled, becoming the upper edge sealing section.

[0021] (Components) The pouch with a spout in this embodiment has a total of three films: a hexagonal front film 17, a back film 18 with the same shape as the front film 17, and a rectangular bottom film 19, as well as a spout portion 3. The front film 17 and the back film 18 are shaped by cutting out two roughly triangular portions from a rectangular film when viewed from the front. In this embodiment, the pouch with a spout has a mounting edge seal portion 7 formed by sandwiching the mounting portion 3b of the spout portion 3 between the front film 17 and the back film 18 and then heat sealing it. The mounting edge seal portion 7 fixes the spout portion 3 to the main body 1 while it is sandwiched between the front film 17 and the back film 18. The bottom film 19 is folded in half and is divided into a first portion and a second portion with the folded portion 19a as the boundary. The bottom film 19 is provided with four semi-circular side edge notches that cut out the side edges, and these side edge notches are positioned to overlap when the film is folded in half. The second bottom seal portion, described later, is formed through these side edge notches. Holes may be used instead of side edge notches.

[0022] (Each seal section) Of the side edge sealing portion 5, the side closer to the spout portion 3 is called the first side edge sealing portion 5a, and the side further from the spout portion 3 is called the second side edge sealing portion 5b. The side edge sealing portion 5 seals the front film 17 and the back film 18. The side edge sealing portion 5 is a sealing portion provided along the first side edge portion 33 and the second side edge portion 34 that extend vertically from the folded portion 19a in the main body portion 1. Of these, the second side edge sealing portion 5b is formed extending from the folded portion 19a to a part of the upper side edge portion 36 of the main body portion 1. The first side edge sealing portion 5a and the second side edge sealing portion 5b are preferably formed with a width of 2 mm to 15 mm, and more preferably with a width of 4 mm to 10 mm.

[0023] The bottom seal portion 6 is composed of a first bottom seal portion and a second bottom seal portion. The first bottom seal portion seals the front film 17 and the bottom film 19, and the back film 18 and the bottom film 19, respectively. The second bottom seal portion seals the front film 17 and the back film 18. The second bottom seal portion is formed in a position that overlaps with the side edge notch formed in the bottom film 19. A mounting edge seal portion 7 is provided along the mounting edge 35 of the main body portion 1. The mounting edge seal portion 7 is formed to extend along the mounting edge 35. Therefore, the mounting edge seal portion 7 extends diagonally from the upper edge 31 to the first side edge 33 of the main body portion 1.

[0024] The main body 1 has a flow path forming seal portion for forming a flow path 27 that is continuous with the spout portion 3. The flow path forming seal portion is a pair consisting of a first flow path forming seal portion 25 and a second flow path forming seal portion 26. The first flow path forming seal portion 25 and the second flow path forming seal portion 26 are joined to the front film 17 and the back film 18, and a flow path 27 for the contents is formed between the first flow path forming seal portion 25 and the second flow path forming seal portion 26. There are no particular limitations on the shape of the first flow path forming seal portion 25 and the second flow path forming seal portion 26, but it is preferable that they are continuous with the mounting edge seal portion 7 so that the contents from the flow path can easily flow into the spout portion 3. The first flow path forming seal portion 25 is connected to the mounting edge seal portion 7 and reaches the first side edge seal portion 5a. The second flow path forming seal portion 26 is continuous with the mounting edge seal portion 7 and reaches the upper edge portion 31.

[0025] The first channel-forming seal portion 25 and the second channel-forming seal portion 26 have opposing edges 25a and 26a, which are straight edges, on their opposing sides. These opposing edges 25a and 26a are formed to be parallel to each other or to narrow towards the spout portion 3. The angle between the opposing edges 25a and 26a is preferably 0° to 20°, and more preferably 0° to 10°. If the widening toward the center of the storage portion 10 is too large, the opening on the center side of the storage portion 10 will be too wide, making it difficult to smoothly flow the contents into the spout portion 3. In the example in Figure 1, the angle between the opposing edges 25a and 26a is 0°, and they are parallel to each other.

[0026] (Flow channel) The flow path 27 is the portion sandwiched between the first flow path forming seal portion 25 and the second flow path forming seal portion 26. Because the first flow path forming seal portion 25 and the second flow path forming seal portion 26 are continuous with the mounting edge seal portion 7, the cavity of the cylindrical part of the spout portion 3 and the flow path 27 are continuous. As a result, the contents that pass through the flow path 27 flow into the spout portion 3. The opposing edges 25a and 26a may be parallel to each other, or they may be formed to narrow as they approach the spout portion 3. Therefore, as shown in Figure 2, if W1 is the distance between the opposing edges 25a and 26a at the boundary with the mounting edge seal portion 7, and W2 is the distance between the opposing edges 25a and 26a at the position furthest from the mounting edge seal portion 7, then W1 ≤ W2. When the opposing edges 25a and 26a are parallel, W1 = W2.

[0027] The size of the distance W1 between opposing edges 25a and 26a at the boundary with the mounting edge seal portion 7 is not particularly limited, but it is preferable that W1 ≥ D when the inner diameter of the spout portion 3 is D. The distance between opposing edges 25a and 26a is the width of the flow path 27. Therefore, it is preferable that the width of the flow path 27 at the boundary between the mounting edge seal portion 7 and the flow path 27 is greater than or equal to the inner diameter of the spout portion 3. The inner diameter of the spout portion 3 is the inner diameter of the cavity that becomes the spout in the spout portion 3. In this embodiment, the mounting portion 3b of the spout portion 3 reaches the boundary between the mounting edge seal portion 7 and the first flow path forming seal portion 25 and the second flow path forming seal portion 26. Therefore, the boundary between the mounting edge seal portion 7 and the first flow path forming seal portion 25 and the second flow path forming seal portion 26 is also the boundary between the spout portion 3 and the first flow path forming seal portion 25 and the second flow path forming seal portion 26. At the boundary between the spout section 3 and the flow path 27, the distance W1 (width of the flow path 27) between the opposing edges 25a and 26a is greater than or equal to the inner diameter D of the spout section 3, which facilitates the flow of contents from the flow path 27 to the spout section 3.

[0028] Here, we define the range of the flow path 27. As shown in Figure 2, the points furthest from the mounting edge 35 in the first flow path forming seal section 25 and the second flow path forming seal section 26 are defined as the innermost points 25b and 26b, respectively. Then, the flow path 27 is defined as the area from the line segment connecting the innermost points 25b and 26b towards the spout section 3. In Figure 2, the hypothetical line segment connecting the innermost points 25b and 26b is shown as a dashed line.

[0029] (Bottom gusset section) The bottom film 19 is divided into a first part and a second part by a folded portion 19a. The first part of the bottom film 19 and the portion of the front film 17 corresponding to the first part of the bottom film 19 form a first pleat, and the second part of the bottom film 19 and the portion of the back film 18 corresponding to the second part of the bottom film 19 form a second pleat. The bottom gusset portion 13 is formed by the first pleat and the second pleat. In Figure 1, the first pleat is visible, and the second pleat is hidden by the first pleat.

[0030] (Film composition) The front film 17, back film 18, and bottom film 19 can be made of laminated films. The laminated film includes at least a base layer and a sealant layer. The sealant layer is the innermost layer of the pouch. The base layer is a uniaxially oriented or biaxially oriented plastic film. As materials for the base layer, for example, polyamides such as nylon (Ny), polyesters such as polyethylene terephthalate (PET), or polypropylene (PP) can be used.

[0031] The thickness of the base layer is set appropriately depending on the material used. For example, when nylon is used as the material constituting the base layer, the thickness of the base layer is in the range of 15 to 25 μm. When polyethylene terephthalate is used as the material constituting the base layer, the thickness of the base layer is in the range of 12 to 25 μm. The laminated film may also consist of multiple base layers. For example, the laminated film may consist of a nylon film as the first base layer and a polyethylene terephthalate film as the second base layer.

[0032] Next, the sealant layer will be described. The sealant layer is a layer that acts as a sealant to seal the front film 17 and the back film 18, and contains a thermoplastic resin. As the thermoplastic resin, for example, polyethylene (PE) or polypropylene (PP) can be used. Here, polyethylene includes not only homopolymers of ethylene, but also copolymers that are generally recognized as polyethylene, such as copolymers of ethylene and α-olefin monomers. Furthermore, as the polyethylene used in the sealant layer, low-density polyethylene (LDPE) and linear low-density polyethylene (LLDPE) can be suitably used. Note that the laminated film may have multiple sealant layers. The thickness of the sealant layer is set appropriately depending on the material used. For example, the thickness of the sealant layer is preferably in the range of 20 to 200 μm, and more preferably in the range of 30 to 130 μm.

[0033] The laminated film may have a printed layer to display product information or to enhance its aesthetic appeal. The printed layer may be located on the outside of the substrate layer or between the substrate layer and the sealant layer. The printed layer can be formed from a printing ink containing a binder and a pigment.

[0034] Although not shown in the diagram, the laminated film may further include a functional layer. Examples of functional layers include barrier layers for enhancing the barrier properties of the laminated film against gases and liquids. The specific composition of the barrier layer is not particularly limited, but examples include a vapor-deposited layer containing inorganic materials such as aluminum formed by vapor deposition, or inorganic oxides such as aluminum oxide or silicon oxide, a metal foil layer such as aluminum, or an ethylene-vinyl alcohol copolymer layer formed by coating, specifically EVAL (EVOH). The functional layer may be laminated on the outside of the substrate layer, or it may be laminated between the substrate layer and the sealant layer.

[0035] The method for laminating the base layer, sealant layer, and functional layer is not particularly limited, and known lamination methods can be used as appropriate. For example, a so-called dry lamination method, which involves bonding with an adhesive, may be used, or an extrusion lamination method may be used.

[0036] The laminated film may have an antistatic function to prevent contents such as powder from adhering to the main body 1. This makes the laminated film a packaging material with antistatic properties. For example, an antistatic layer can be provided by adding aluminum powder to the printing layer or adhesive.

[0037] (Spout part) The dispensing outlet 3 is a plastic molded body and can be molded, for example, using injection molding. The dispensing outlet 3 has a hollow cylindrical portion, which communicates with the storage portion 10 at the boundary with the flow path 27. This allows the contents to be dispensed from the storage portion 10.

[0038] (Embossed area) The spout section 3 has a cavity inside that serves as the spout. Let M be the axis of this cavity. In Figure 2, the axis M is shown by a dashed line. The axis is a straight line that extends infinitely through the cavity of the spout section 3. In this case, the direction in which the contents are dispensed is the direction in which the axis M extends. As shown in Figure 2, the main body section 1 has an embossed section 11 at a position that coincides with the axis M. The planar shape of the embossed section 11 can be any shape, such as a circle, ellipse, polygon, etc., but in this embodiment it is circular. The embossed section 11 has two levels of height in the direction normal to the main body section 1. In Figure 2, the embossed section 11 is shown as a double circle, and the inside of the inner circle is higher than the inside of the outer circle.

[0039] It is preferable that part or all of the embossed portion 11 is included in the flow path 27. It is more preferable that the entire embossed portion 11 is included in the flow path 27. In the example in Figure 2, the embossed portion 11 overlaps with the line segment connecting the innermost point 25b and the innermost point 26b. Therefore, a part of the embossed portion 11 is included in the flow path 27.

[0040] When the pouch with a spout is tilted downwards from an upright position to dispense the contents, the contents move from the bottom towards the spout. Since a portion of the embossed portion 11 is included in the flow path 27, blockage near the entrance of the flow path 27 can be suppressed. As a result, the contents contained in the central part of the storage portion 10 and near the bottom gusset portion 13 pass smoothly through the flow path 27 and are easily dispensed from the spout 3.

[0041] The maximum width L of the embossed portion 11 is preferably 10 mm or more and 30 mm or less, and more preferably 15 mm or more and 25 mm or less. The maximum width L is the distance between the furthest points in the planar shape of the embossed portion 11, and if the planar shape of the embossed portion 11 is a circle, it is the diameter.

[0042] Figure 3 is a cross-sectional view of the embossed portion 11. The embossed portion 11 can be formed by pressing the front film and the back film 18 with a male and female die. As shown in Figure 3, both the front film 17 and the back film 18 of the embossed portion 11 are formed to protrude from the inner side (the side of the housing portion 10) of the main body portion 1 toward the outer side.

[0043] In particular, the embossed portion 11 in this embodiment has two height levels, and the outer diameters of the first and second levels are concentric circles. The height of the embossed portion 11 is the height in the direction normal to the surface on which the embossed portion is formed. That is, if it is formed on the front film 17, it is the height in the direction normal to the front film 17, and if it is formed on the back film 18, it is the height in the direction normal to the back film 18. In this embodiment, the embossed portion 11 has two height levels in the direction normal to the surface on which the embossed portion is formed. The vertical direction in Figure 3 is the direction normal to the surface on which the embossed portion is formed, and it indicates the height of the embossed portion. As shown in Figure 3, in this embodiment, in a cross-sectional view, the side surface of the embossed portion 11 is vertically rising. However, it is not limited to this shape, and for example, in a cross-sectional view, it may be substantially trapezoidal, or the cross-sectional shape may be substantially arc-shaped. Furthermore, as shown in Figure 2, the embossed portion 11 may be provided on both the front film 17 and the back film 18, or it may be formed on either the front film 17 or the back film 18.

[0044] <Second Embodiment> A second embodiment will now be described. Figure 4 is a front view showing a pouch with a spout according to the second embodiment of this disclosure. In Figure 4, the same reference numerals are used for parts that are the same as in the first embodiment, and their description is omitted. In the second embodiment, the embossed portion differs from that of the first embodiment. As shown in the figure, the embossed portion 11 in the first embodiment had a two-stage structure, but the embossed portion 11a in the second embodiment has a single-stage structure. Also, in the second embodiment, the embossed portion 11 is entirely contained within the flow path 27.

[0045] Figure 5 is a cross-sectional view of the embossed portion 11a. The embossed portion 11a can be formed by pressing the front film 17 and the back film 18 with a male and female die, similar to the embossed portion 11 in the first embodiment. As shown in Figure 5, both the front film 17 and the back film 18 of the embossed portion 11a are formed to protrude from the inner side (the side of the housing portion 10) of the main body portion 1 toward the outer side.

[0046] As shown in Figure 5, in this embodiment, the side surface of the embossed portion 11a is vertically rising in a cross-sectional view. However, the shape is not limited to this, and for example, the cross-sectional shape may be substantially trapezoidal, or the cross-sectional shape may be substantially arc-shaped. Also, as shown in Figure 5, the embossed portion 11a may be provided on both the front film 17 and the back film 18, or it may be formed on either the front film 17 or the back film 18.

[0047] The maximum width L of the embossed portion 11a is preferably 10 mm to 30 mm, and more preferably 15 mm to 25 mm, similar to the embossed portion 11 shown in the first embodiment. The maximum width L of the embossed portion 11a is the distance between the furthest points in the planar shape of the embossed portion 11a, and if the planar shape of the embossed portion 11a is a circle, it is the diameter.

[0048] <Third Embodiment> A third embodiment will now be described. Figure 6 is a front view showing a pouch with a spout according to the third embodiment of this disclosure. In Figure 6, the same reference numerals are used for parts that are the same as in the first and second embodiments, and their description is omitted. In the third embodiment, as in the second embodiment, the embossed portion 11a has a single-stage structure. Furthermore, in the third embodiment, the embossed portion 11a is not only entirely contained within the flow path 27, but is also entirely contained within the area sandwiched between the opposing edges 25a and 26a.

[0049] Furthermore, in the third embodiment, the upper edge 36 is curved in a convex shape toward the storage section 10. That is, in the third embodiment, the upper edge 36 is recessed inward toward the storage section 10. As a result, when you grasp the upper edge 36 with your hand, your fingertips reach a part closer to the center, making it easier to grasp the pouch with a spout and pour out the contents, even if it is relatively heavy.

[0050] In the third embodiment, the lower edge 25c of the first channel forming seal portion 25 is parallel to the lower edge 32 of the pouch. Also in the third embodiment, the side edge 26c of the second channel forming seal portion 26 is parallel to the first side edge 33 and the second side edge 34 of the pouch.

[0051] <Fourth Embodiment> A fourth embodiment will now be described. Figure 7 is a front view showing a pouch with a spout according to the fourth embodiment of this disclosure. In Figure 7, the same reference numerals are used for parts that are the same as in the first to third embodiments, and their description is omitted. In the fourth embodiment, the shape of the second side edge seal portion 5b differs from that of the second embodiment. In the second embodiment, the second side edge seal portion 5b is formed only in the portion along the second side edge portion 34, and only the upper end of the second side edge seal portion 5b reaches the upper side edge portion 36. In contrast, in the fourth embodiment, the second side edge seal portion 5b extends from the portion along the second side edge portion 34 further along the upper side edge portion 36.

[0052] <Fifth Embodiment> A fifth embodiment will now be described. Figure 8 is a front view showing a pouch with a spout according to the fifth embodiment of this disclosure. In Figure 8, the same reference numerals are used for parts that are the same as in the first to fourth embodiments, and their description is omitted. In the fifth embodiment, the shapes of the first channel forming seal portion 25 and the second channel forming seal portion 26 are the same as in the first and second embodiments. That is, the lower edge 25c of the first channel forming seal portion 25 is inclined to approach the lower edge portion 32 as it approaches the side edge portion. Also, the side edge 26c of the second channel forming seal portion 26 is inclined to approach the upper side edge portion 36 as it approaches the upper edge portion 31.

[0053] <Sixth Embodiment> A sixth embodiment will now be described. Figure 9 is a front view showing a pouch with a spout according to the sixth embodiment of this disclosure. In Figure 9, the same reference numerals are used for parts that are the same as those in the first to fifth embodiments, and their description is omitted. The sixth embodiment is the same as the fifth embodiment except that it does not have a bottom gusset and is not a standing pouch. In the sixth embodiment, the main body 1 of the pouch with a spout is composed of a front film 17 and a back film 18, and does not have a bottom film 19. Therefore, the first side edge sealing portion 5a, the second side edge sealing portion 5b, and the bottom sealing portion 6 are all directly joined to the front film 17 and the back film 18.

[0054] <Seventh Embodiment> A seventh embodiment will now be described. Figure 10 is a front view showing a pouch with a spout according to the seventh embodiment of this disclosure. In Figure 10, the same reference numerals are used for parts that are the same as those in the first to sixth embodiments, and their descriptions are omitted. The seventh embodiment, like the sixth embodiment, does not have a bottom gusset and is not a standing pouch. In the seventh embodiment, the upper edge 36 is longer laterally than in the sixth embodiment. That is, in the direction connecting the first side edge 33 and the second side edge 34, the upper edge 36 is longer than in the sixth embodiment. Also, in the sixth embodiment, the boundary between the upper edge 36 and the upper edge 31 is rounded, whereas in the seventh embodiment, the boundary between the upper edge 36 and the upper edge 31 is angular.

[0055] <Eighth Embodiment> The eighth embodiment will now be described. Figure 11 is a front view showing a pouch with a spout according to the eighth embodiment of this disclosure. In Figure 11, the same reference numerals are used for parts that are the same as in the first to seventh embodiments, and their description is omitted. The eighth embodiment differs from the first embodiment in that an upper edge seal portion is formed over the entire upper edge portion 36. The formation of the upper edge seal portion 8 narrows the opening for filling, but a stable structure can be obtained even during filling. Also, in the eighth embodiment, as in the third and fourth embodiments, the lower edge 25c of the first flow path forming seal portion 25 is parallel to the lower edge portion of the pouch. Also, in the eighth embodiment, as in the third and fourth embodiments, the side edge 26c of the second flow path forming seal portion 26 is parallel to the side edge portion of the pouch.

[0056] <Ninth Embodiment> The ninth embodiment will now be described. Figure 12 is a front view showing a pouch with a spout according to the ninth embodiment of this disclosure. In Figure 12, the same reference numerals are used for parts that are the same as in the first to eighth embodiments, and their description is omitted. The ninth embodiment differs from the eighth embodiment in that only a portion of the upper edge 36 has a seal. Otherwise, it is the same as the eighth embodiment. The upper end of the second side edge seal 5b is formed along a portion of the upper edge 36, similar to the first embodiment.

[0057] While preferred embodiments of the present disclosure have been described above, the present disclosure is not limited to the above embodiments, and various modifications are possible. For example, in the above embodiments, the front film, back film, and bottom film may be made of three separate films, but they may also be made of two or one film. For example, the pouch may be made using a single film in which the front film, bottom film, and back film are connected, or the main body 1 may be made using a total of two films consisting of a front film and a film in which the back film and bottom film are connected.

[0058] Furthermore, while the first to fifth, eighth, and ninth embodiments described above use a standing pouch shape with a bottom gusset, it may also be a so-called flat pouch shape composed of a front film and a back film. Also, while the sixth and seventh embodiments described above use a flat pouch shape without a bottom gusset, it may also be a standing pouch shape with a bottom gusset.

[0059] Furthermore, although the one-stage embossed portion and the two-stage embossed portion were used in specific embodiments in the above embodiment, the one-stage embossed portion and the two-stage embossed portion may be used in any embodiment. [Explanation of Symbols]
