[0017] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. FIGS. 1 to 12 are diagrams showing an embodiment. Each of the following diagrams is a schematic diagram. Therefore, the size and shape of each part are appropriately exaggerated to facilitate understanding. In addition, the present invention can be modified appropriately within the scope of the technical concept. In each of the following diagrams, the same parts are given the same reference numerals, and some detailed explanations may be omitted. In addition, the numerical values ​​such as the dimensions of each member and the material names described in this specification are examples of embodiments, and are not limited to these, and can be appropriately selected and used. In this specification, terms that specify shapes and geometric conditions, such as parallel, orthogonal, and vertical, are interpreted to include substantially the same state in addition to their strict meanings. In addition, in this specification, "upper" and "lower" refer to the upper and lower sides of the spout combination 10 in an upright state (FIG. 1), respectively.

[0018] (Pour spout assembly) First, a spout combination 10 according to the present embodiment will be outlined with reference to Figs. 1 to 4.

[0019] As shown in FIG. 1, a spout combination 10 according to this embodiment includes a main body 20, a cap 30, and a sealing member 40.

[0020] 2 to 4, main body 20 has spout 21 including a screw portion 23 (see FIG. 4), and joint 22 located below spout 21. Spout 21 is formed with a first through hole 24 that is generally circular in plan view.

[0021] The cap 30 is screwed onto the screw portion 23. A second through hole (through hole) 31 into which the spout 21 is inserted is formed in the cap 30. The second through hole 31 is formed with a screw portion 32 (see FIG. 4) that screws onto the screw portion 23.

[0022] As shown in FIG. 1, the sealing member 40 is sealed to the main body 20 and the cap 30 , and closes the second through hole 31 of the cap 30 .

[0023] (Main body) Next, the main body 20 will be described with reference to Figures 4 to 6. The main body 20 pours out the contents in a pouch 51 (see Figure 9) which will be described later.

[0024] As described above, the main body 20 has the spout 21 including the screw portion 23 and the joint portion 22 located below the spout 21. The spout 21 and the joint portion 22 are integrally molded by, for example, an injection molding method using a thermoplastic resin. The resin used for the main body 20 may be a resin that is heat-sealed to the inner layer 63 (see FIG. 10) of the laminate 60 constituting the pouch 51 described later. Examples of the resin used for the main body 20 include low-density polyethylene, medium-density polyethylene, high-density polyethylene, linear low-density polyethylene, polypropylene, and ethylene-propylene copolymer. When a retort sterilization process is performed on the container 50 with a spout described later, the resin used for the main body 20 is preferably polypropylene or an ethylene-propylene copolymer.

[0025] The spout 21 has a hollow cylindrical shape. As described above, the spout 21 has a first through hole 24 that is generally circular in plan view. This first through hole 24 extends vertically along the axial direction of the spout 21. The first through hole 24 communicates with the inside of a pouch 51, which will be described later, and the contents accommodated in the pouch 51 are poured out to the outside through this first through hole 24.

[0026] Next, the joint portion 22 of the main body portion 20 will be described. The joint portion 22 is a portion that is joined to a pouch 51 described later. In this embodiment, the joint portion 22 is formed in a boat shape. As shown in Figs. 4 to 6, the joint portion 22 includes a central portion 25 and tip portions 26 that are formed on both sides of the central portion 25 and have a generally triangular shape in plan view. The planar shape of the central portion 25 is a rectangular shape in which the long side of the four sides includes an arc shape. In addition, a third through hole 27 that is generally circular in plan view is formed in the central portion 25. This third through hole 27 extends vertically along the axial direction of the spout 21. The third through hole 27 communicates the first through hole 24 of the spout 21 with the inside of the pouch 51 described later.

[0027] As described above, the tip portion 26 is formed on both sides of the central portion 25. The planar shape of the tip portion 26 is substantially triangular. This improves the adhesion between the joint portion 22 and the sealing member 40 when the sealing member 40 is joined to the joint portion 22. This prevents a gap from being generated between the joint portion 22 and the sealing member 40, and improves the gas barrier properties of the container with a spout 50. In addition, when the pouch 51 is joined to the portion corresponding to the joint portion 22, the adhesion between the portion corresponding to the joint portion 22 and the pouch 51 can be improved. This prevents a gap from being generated between the portion corresponding to the joint portion 22 and the pouch 51, and prevents the content from leaking out of the container with a spout 50. The tip portion 26 may have a hollowed-out portion 26a (see FIG. 5). This reduces the amount of resin used. Furthermore, the hollowed-out portion 26a prevents sink marks (dents) caused by the shrinkage of the resin. This prevents a decrease in welding suitability.

[0028] As described above, the sealing member 40 is sealed to the main body 20. In this case, the sealing member 40 is sealed to the upper surface of the spout 21 and part of the side surface of the joint portion 22 (see FIG. 1).

[0029] (cap) Next, the cap 30 will be described with reference to Figures 4, 7 and 8. The cap 30 is detachable from the spout 21 of the main body 20.

[0030] In this embodiment, the planar shape of the cap 30 is the same as the planar shape of the main body 20 (the joint portion 22). Therefore, the cap 30 is formed in a boat shape.

[0031] As shown in Figs. 4, 7 and 8, the cap 30 includes a central portion 33 and tip portions 34 formed on both sides of the central portion 33 and having a triangular shape in plan view. The planar shape of the central portion 33 is a square shape in which a pair of opposing sides among the four sides include an arc shape. The second through hole 31 described above is also formed in the central portion 33. This second through hole 31 has a substantially circular shape in plan view and extends up and down along the axial direction of the spout 21. The second through hole 31 is configured so that the spout 21 is inserted into it. For this reason, the inner diameter of the second through hole 31 is larger than the outer diameter of the spout 21.

[0032] As described above, the tip portions 34 are formed on both sides of the central portion 33. The planar shape of the tip portions 34 is generally triangular. This improves the adhesion between the cap 30 and the sealing member 40 when joining the cap 30 to the sealing member 40. This makes it possible to prevent a gap from being generated between the cap 30 and the sealing member 40, and improves the gas barrier properties, etc. of the container 50 with a pouring spout.

[0033] The tip 34 protrudes upward from the central portion 33. The upper surface 35 of the tip 34 is inclined upward as it moves away from the central portion 33. This makes it easier to fold the sealing member 40 in half along the cap 30 when the sealing member 40 is made of a single film as described below. This makes it possible to suppress the occurrence of wrinkles in the sealing member 40 when the sealing member 40 is sealed to the main body 20 and the cap 30. As a result, it is possible to suppress the deterioration of the design of the spout-equipped container 50 (see FIG. 9) described below. In addition, since the occurrence of wrinkles in the sealing member 40 can be suppressed, it is possible to effectively suppress the occurrence of unexpected gaps and sealing failures (i.e., it is possible to improve the welding suitability). Even if wrinkles occur in the sealing member 40, it is possible to achieve complete sealing by squashing the wrinkles and sealing. Such a tip 34 may have a hollowed-out portion 34a (see FIG. 7). This makes it possible to reduce the amount of resin used. Furthermore, by forming the hollowed-out portion 34a, it is possible to suppress sink marks (dents) caused by the shrinkage of the resin, and therefore it is possible to suppress a decrease in the weldability.

[0034] The central portion 33 and the tip portion 34 are integrally molded, for example, by injection molding using a thermoplastic resin. Examples of the resin used for the cap 30 include low-density polyethylene, medium-density polyethylene, high-density polyethylene, linear low-density polyethylene, polypropylene, and an ethylene-propylene copolymer. When a retort sterilization process is performed on the container 50 with a spout, which will be described later, the resin used for the cap 30 is preferably polypropylene or an ethylene-propylene copolymer.

[0035] As described above, the sealing member 40 is sealed in the cap 30. In this case, the sealing member 40 seals the entire area of ​​the cap 30 except for the lower surface thereof (see FIG. 1).

[0036] (Sealing member) Next, we will explain the sealing member (first sealing member) 40. The sealing member 40 is a member that is sealed to the main body 20 and the cap 30 to hermetically seal the container 50 with a spout, which will be described later, and improves the gas barrier properties of the container 50 with a spout.

[0037] This sealing member 40 completely covers the outwardly exposed portions of the outer surfaces of the main body 20 and the cap 30 in a container with a spout 50 (see FIG. 9) described below (see FIGS. 1 and 9). This improves the sealing performance of the container with a spout 50, and also improves the gas barrier properties and sanitation of the container with a spout 50. Furthermore, since the container with a spout 50 can be sealed, the contents filled in the container with a spout 50 can be subjected to retort sterilization.

[0038] Further, a notch 41 is formed in the sealing member 40. This notch 41 is a cutout or incision that is V-shaped or the like in a plan view. In the illustrated example, a V-shaped cutout is formed on the outer edge of the sealing member 40. By providing such a notch 41 in the sealing member 40, it becomes easier for a user to break the sealing member 40 when breaking the sealing member 40.

[0039] The sealing member 40 is made of a single film. This makes it possible to reduce the area of ​​the end face of the film exposed to the outside in a container 50 with a spout (see FIG. 9) described below. This makes it possible to further improve the sealing performance, gas barrier performance, and hygiene of the container 50 with a spout.

[0040] The sealing member 40 has gas barrier properties. The sealing member 40 has gas barrier properties, and therefore the gas barrier properties of the container with a spout 50 can be improved. This makes it possible to suppress, for example, oxidation of the contents due to oxygen permeation. For this reason, the container with a spout 50 can be suitably used for applications that require long-term storage, such as drinking water for emergencies, hydrogen water, or liquid preparations for medical use. Here, in the container with a spout 50, gas barrier properties can be imparted to the laminate 60 used in the pouch 51 described below. On the other hand, it may be difficult to impart gas barrier properties to the main body 20 and cap 30 of the spout combination 10, taking into consideration the molding method and the materials used. For this reason, gas (water vapor, oxygen, etc.) may penetrate into the inside of the container with a spout 50 from the main body 20 or the cap 30. In response to this, by covering the main body 20 and the cap 30 with the sealing member 40 having gas barrier properties, it is possible to block the route through which gas (water vapor, oxygen, etc.) from the outside penetrates into the container with a spout 50. This improves the gas barrier properties of the container 50 with a pouring spout.

[0041] Moreover, it is preferable that the sealing member 40 has heat resistance that allows it to be applied to a retort sterilization treatment. In order to satisfy such a property, it is preferable that the sealing member 40 is made of a film made of a laminate.

[0042] In the laminate constituting the sealing member 40, a resin of an interlayer peeling type or a cohesive peeling type having an easy peeling property with respect to the main body part 20 and the cap 30 (for example, ethylene-propylene rubber (EPR)) may be used as the sealant layer sealed to the main body part 20 and the cap 30. When a resin of an interlayer peeling type is used as the sealant layer, a film in which the sealant layer and another layer are co-extruded in two or three layers may be used. In this case, by lowering the adhesive strength between the sealant layer and the other layer, the other layer can be peeled off from the sealant layer when the cap 30 is rotated with respect to the main body part 20, as described later. This makes it easier to peel off the sealing member 40 from the spout 21. When a resin of a cohesive peeling type is used as the sealant layer, a sealant layer in which random polypropylene, elastomer, etc. are mixed at a predetermined ratio may be used. In this case, when the cap 30 is rotated with respect to the main body part 20, the sealant layer undergoes cohesive failure, and the sealing member 40 can be peeled off from the spout 21.

[0043] A specific layered structure of the laminate used in the sealing member 40 will be described below. (1) CPP (30 μm) or LLDPE (30 μm) / AL (7 μm to 15 μm) / CPP (30 μm), LLDPE (30 μm) or EPR (30 μm) (sealant layer side) (2) CPP (30 μm) or LLDPE (30 μm) / VMPET (12 μm) / CPP (30 μm), LLDPE (30 μm) or EPR (30 μm) (sealant layer side) (3) CPP (30 μm) or LLDPE (30 μm) / VMON (12 μm) / CPP (30 μm), LLDPE (30 μm) or EPR (30 μm) (sealant layer side) In addition, "CPP" means unoriented polypropylene film (as below). "LLDPE" means linear low density polyethylene. "AL" means aluminum foil (as below). "EPR" means ethylene propylene rubber (as below). "VMPET" means aluminum vapor-deposited polyethylene terephthalate (PET) (as below). "VMON" means aluminum vapor-deposited nylon (ON).

[0044] (Container with spout) Next, a container with a spout 50 according to the present embodiment will be described with reference to Fig. 9. As shown in Fig. 9, the container with a spout 50 includes a pouch (container body) 51 and a spout combination 10 attached to the pouch 51.

[0045] Among these, the pouch 51 is a so-called four-sided bag. The pouch 51 includes a pair of main sheets 52a, 52b arranged opposite each other, and the pair of overlapping main sheets 52a, 52b are heat-sealed to each other near side edges 53, near upper edges 54, and near lower edges 55. A storage space 50a for storing contents is defined within the space surrounded by the pair of main sheets 52a, 52b.

[0046] In addition, a spout combination 10 is attached to the center of the upper part of the pouch 51. The spout combination 10 is disposed between a pair of overlapping main surface sheets 52a, 52b. In this manner, the upper part of the pouch 51 is closed by the pair of main surface sheets 52a, 52b and the spout combination 10. In addition, the pair of main surface sheets 52a, 52b cover the end faces of the film constituting the sealing member 40. In this case, the lower end of the sealing member 40 is disposed within the heat-sealed region.

[0047] 9 shows an example in which the pouch 51 is a four-sided pouch, but is not limited thereto. For example, although not shown, the pouch 51 may be a standing pouch, a gusseted pouch, or a flat bag such as a three-sided pouch.

[0048] As the main sheets 52a and 52b used in the pouch 51, a laminate 60 as shown in FIG.

[0049] 10, the laminate 60 includes an outer layer 61, an intermediate layer 62, and an inner layer 63. The outer layer 61, the intermediate layer 62, and the inner layer 63 can be laminated together by, for example, a dry lamination method in which a urethane-based or other dry lamination adhesive is used for lamination, or an extrusion lamination method in which a polyolefin-based resin or the like is hot-melt extruded for lamination. When the pouch 51 is subjected to retort sterilization treatment, it is preferable to use the dry lamination method as a method for laminating the outer layer 61, the intermediate layer 62, and the inner layer 63 together.

[0050] The outer layer 61 is a basic material constituting the pouch 51. As the outer layer 61, a synthetic resin film having excellent mechanical, physical, and chemical properties may be used. As the outer layer 61, for example, a biaxially oriented film such as polypropylene, polyethylene terephthalate, nylon, etc. may be used. Alternatively, as the outer layer 61, a film obtained by evaporating an inorganic material such as aluminum, aluminum oxide, silicon oxide, indium oxide, tin oxide, zirconium oxide, etc. onto the above-mentioned film to provide a vapor deposition layer may be used. Usually, the outer layer 61 is often printed, and printability is required. For this reason, the film constituting the outer layer 61 is preferably a biaxially oriented film. The thickness of the film constituting the outer layer 61 may be a thickness that provides the minimum necessary characteristics such as strength and rigidity as a basic material. The thickness of the outer layer 61 may be, for example, about 9 μm to 50 μm.

[0051] The intermediate layer 62 is a layer provided when the pouch 51 is required to have rigidity, light-shielding properties, gas barrier properties, or the like due to packaging conditions, transportation conditions, or protective function conditions for the contents. The intermediate layer 62 may be the film used for the outer layer 61, a film provided with the vapor deposition layer, or a metal foil such as aluminum or iron. Alternatively, the intermediate layer 62 may be a laminate of one or more of these films. Depending on the required properties, the laminate 60 may not include the intermediate layer 62.

[0052] The inner layer 63 is a layer for bonding the laminates 60 together. A heat-sealable resin may be used as the inner layer 63. When the pouch 51 is subjected to a retort sterilization treatment, the inner layer 63 may be made of unstretched polypropylene or unstretched polypropylene (CPP) in which an elastomer component is blended with polypropylene, or high density polyethylene (HDPE). When the pouch 51 is subjected to a boiling treatment, the inner layer 63 may be made of an unstretched film such as low density polyethylene (LDPE), medium density polyethylene (MDPE), linear low density polyethylene (LLDPE), ethylene-vinyl acetate copolymer (EVA), ionomer, ethylene-acrylic acid copolymer (EAA), ethylene-ethyl acrylate copolymer, or ethylene-methacrylic acid copolymer.

[0053] Specific examples of the laminate 60 constituting the pouch 51 will be shown below. PET / DL / AL / DL / ON / DL / CPP or LLDPE (inner layer) PET / DL / ON / DL / AL / DL / CPP or LLDPE (inner layer) Vapor-deposited PET / DL / ON / DL / CPP or LLDPE (inner layer) PET / DL / Vapor deposition ON / DL / CPP or LLDPE (inner layer) Vapor-deposited PET / DL / CPP or LLDPE (inner layer) Coated PET / DL / CPP or LLDPE (inner layer) Vapor deposition ON / DL / CPP or LLDPE (inner layer) PET / DL / Vapor-deposited PET / DL / ON / DL / CPP or LLDPE (inner layer) PBT / DL / AL / DL / CPP or LLDPE (inner layer) In addition, "vapor-deposited PET" means PET with silicon oxide or aluminum oxide vapor-deposited. "Vapor-deposited ON" means ON with silicon oxide or aluminum oxide vapor-deposited. "DL" means an adhesive layer formed by the dry lamination method. "Coated PET" means PET coated with a barrier substrate such as PVA (polyvinyl alcohol) or PVDC (polyvinylidene chloride).

[0054] Next, the operation of the present embodiment having the above-mentioned configuration will be described. First, a method for manufacturing the container 50 with a spout will be described.

[0055] First, the main body 20 and the cap 30 are separately manufactured by, for example, injection molding.

[0056] Next, as shown in FIG. 11, after the cap 30 is attached to the main body 20, the sealing member 40 is sealed to the main body 20 and the cap 30. The sealing member 40 may be composed of a single film. In this case, for example, the film is arranged so that the sealant layer of the film faces the main body 20 and the cap 30. Then, the film (sealing member 40) is placed over the main body 20 and the cap 30 from above. At this time, the film (sealing member 40) is brought into close contact with the main body 20 and the cap 30 by folding the film. Thereafter, the sealing member 40 is sealed to the main body 20 and the cap 30 by heat sealing. In this manner, the spout combination 10 is obtained.

[0057] Also, a pouch 51 as shown in FIG. 9 is produced. At this time, a pair of main sheets 52a, 52b made of the laminate 60 described above are prepared. Next, for example, the inner layers 63 of each sheet are heat-sealed to each other, and the vicinity of the side edges 53 of the pair of main sheets 52a, 52b are heat-sealed. Next, the main body 20 and the cap 30 (pouring spout combination 10) to which the sealing member 40 is sealed are inserted between the pair of main sheets 52a, 52b from the upper edges of the pair of main sheets 52a, 52b. Thereafter, the pair of main sheets 52a, 52b are joined to the portion of the main body 20 corresponding to the joining portion 22. At this time, the end faces of the film constituting the sealing member 40 are covered by the pair of main sheets 52a, 52b.

[0058] Next, the contents are filled into the pouch 51 to which the main body 20 is attached. At this time, the contents are filled from the lower edges 55 of the main sheets 52a and 52b that are not heat sealed.

[0059] Thereafter, the pair of main sheets 52a, 52b are heat-sealed near their lower edges 55.

[0060] In this manner, a container 50 with a spout is produced.

[0061] Next, a method of using the container 50 with a spout will be described.

[0062] In use, first, the user grasps the sealing member 40 and breaks the sealing member 40 using the notch 41 as a trigger (see FIG. 12(a)).

[0063] Next, after the breakage of the sealing member 40 reaches the vicinity of the cap 30, the user rotates the cap 30 together with the sealing member 40. As a result, as shown in FIG. 12(b), the sealing member 40 is divided into a portion joined to the cap 30 and a portion joined to the main body 20. In this manner, the cap 30 is removed from the main body 20, and the container 50 with a spout is opened. At this time, the portion of the sealing member 40 that was sealed to the upper surface of the spout 21 is peeled off from the upper surface of the spout 21. As a result, a part of the sealing member 40 is removed from the main body 20 together with the cap 30, and the spout 21 is exposed.

[0064] Then, the user removes the contents from the spout 21.

[0065] As described above, according to the present embodiment, the spout combination 10 includes the main body 20 having the spout 21 including the threaded portion 23 and the joint portion 22 located below the spout 21, the cap 30 screwed to the threaded portion 23 and having the second through hole 31 into which the spout 21 is inserted, and the sealing member 40 sealed to the main body 20 and the cap 30 and blocking the second through hole 31 of the cap 30. This allows the cap 30 to be easily removed from the main body 20 by breaking the sealing member 40. Therefore, the spout-equipped container 50 including the spout combination 10 can be easily opened. In addition, since the sealing member 40 blocks the second through hole 31 of the cap 30, the sealing property of the spout-equipped container 50 can be maintained.

[0066] Furthermore, according to this embodiment, the sealing member 40 is made of a single film. This makes it possible to reduce the area of ​​the end face of the film exposed to the outside in the container 50 with a spout. This makes it possible to further improve the sealing performance, gas barrier performance, and hygiene of the container 50 with a spout.

[0067] Furthermore, according to this embodiment, the planar shape of the cap 30 is the same as the planar shape of the main body 20. This makes it possible to prevent wrinkles from occurring in the sealing member 40 when the sealing member 40 is sealed to the main body 20 and the cap 30. This makes it possible to maintain good welding suitability while preventing a decrease in the design of the spout-equipped container 50.

[0068] Moreover, according to this embodiment, the joint 22 and the cap 30 are each formed in a boat shape. As a result, when the sealing member 40 is joined to the joint 22 and the cap 30, the adhesion between the joint 22 and the cap 30 and the sealing member 40 can be improved. Therefore, it is possible to prevent a gap from being generated between the joint 22 and the cap 30 and the sealing member 40, and the gas barrier property and the like of the container with a spout 50 can be improved. Furthermore, when the pouch 51 is joined to the portion corresponding to the joint 22, the adhesion between the portion corresponding to the joint 22 and the pouch 51 can be improved. As a result, it is possible to prevent a gap from being generated between the portion corresponding to the joint 22 and the pouch 51, and the container with a spout 50 can be prevented from having a problem in which the contents leak out.

[0069] Furthermore, according to this embodiment, the cap 30 includes a central portion 33 and tip portions 34 formed on both sides of the central portion 33 and triangular in plan view. The tip portions 34 protrude upward from the central portion 33. The upper surface 35 of the tip portion 34 is inclined upward as it moves away from the central portion 33. This makes it easier to fold the sealing member 40 in half along the cap 30 when the sealing member 40 is made of a single film. This makes it possible to prevent wrinkles from occurring in the sealing member 40 when the sealing member 40 is sealed to the main body portion 20 and the cap 30. As a result, it is possible to more effectively prevent the design of the spout-equipped container 50 from being deteriorated.

[0070] [Variations] Next, a modified example of the spout combination will be described with reference to Figures 13 and 14. In Figures 13 and 14, the same parts as those shown in Figures 1 to 12 are given the same reference numerals and detailed description will be omitted.

[0071] In the above-described embodiment, an example has been described in which the sealing member (first sealing member) 40 blocks the second through hole 31 of the cap 30, but the present invention is not limited to this. For example, as shown in Fig. 13 and Fig. 14, the spout combination 10 may include a sealing member (second sealing member) 45 that is sealed to the cap 30 and blocks the second through hole 31 of the cap 30.

[0072] 13 and 14, the spout 21 of the main body 20 includes a large diameter portion 28 and a small diameter portion 29 provided above the large diameter portion 28. The large diameter portion 28 and the small diameter portion 29 each have a hollow cylindrical shape. The large diameter portion 28 has an outer diameter larger than that of the small diameter portion 29.

[0073] Also in this modification, the planar shape of the cap 30 is the same as that of the main body 20. The inner surface of the cap 30 has a shape corresponding to the spout 21 of the main body 20. Therefore, the cap 30 is configured so that its thickness changes in accordance with the shapes of the large diameter portion 28 and the small diameter portion 29 of the spout 21. Also, in this modification, the upper surface 35 of the tip portion 34 of the cap 30 does not incline, and extends in a direction perpendicular to the axis of the spout 21 in a vertical cross section.

[0074] Next, the sealing member (second sealing member) 45 will be described. The sealing member 45 is a member that is sealed to the upper surface of the spout 21 of the main body 20, the joint portion 22, and the cap 30 to seal the container with a spout 50. This sealing member 45 has a generally circular shape in a plan view, and completely covers the first through hole 24 of the spout 21 and the second through hole 31 of the cap 30. This improves the sealing performance of the container with a spout 50, and also improves the gas barrier properties and sanitation of the container with a spout 50. Furthermore, since the container with a spout 50 can be sealed, retort sterilization of the contents filled in the container with a spout 50 is possible.

[0075] The sealing member (second sealing member) 45 may be formed, for example, of a laminate similar to the laminate constituting the sealing member (first sealing member) 40 described above.

[0076] In this modified example as well, the cap 30 can be easily removed from the main body 20 by breaking the sealing member (first sealing member) 40. At this time, the portion of the sealing member 45 that was sealed to the upper surface of the spout 21 is peeled off from the upper surface of the spout 21. This causes the sealing member 45 to be removed from the main body 20 together with the cap 30, and the spout 21 is exposed. Therefore, in this modified example as well, the container 50 with a spout including the spout combination 10 can be easily opened. In addition, because the sealing member (second sealing member) 45 blocks the second through-hole 31 of the cap 30, the hermeticity of the container 50 with a spout can be maintained.

[0077] The present disclosure is not limited to the above-described embodiment as it is, and in the implementation stage, the components can be modified and embodied without departing from the gist of the disclosure. In addition, various inventions can be formed by appropriate combinations of the multiple components disclosed in the above-described embodiment. Some components may be deleted from all the components shown in the embodiment. [Explanation of symbols]
