[Figure 2] FIG. 2 is a cross-sectional view illustrating an example of a spout member according to an embodiment. [Figure 3] FIG. 2 is a perspective view illustrating a spout member according to an embodiment. [Figure 4] 1 is a front view illustrating a container with a spout according to an embodiment. [Figure 5] 1 is a front view illustrating a state in which a container with a spout according to an embodiment is in use. DETAILED DESCRIPTION OF THE INVENTION

[0010] The present invention will be described below based on preferred embodiments. An example of a spout member according to an embodiment is shown in Figures 1 to 3. Figure 1 is a front view, Figure 2 is a cross-sectional view, and Figure 3 is a perspective view.

[0011] The spout member 10 in the illustrated example has a base end 11a connected to the container 20 (see FIGS. 4 and 5) to pour the contents from the container 20, a tip end 13a from which the contents are poured, and a flow path 12 that connects the base end 11a to the tip end 13a. The base end 11a of the spout member 10 is located on the side closer to the container 20. The tip end 13a of the spout member 10 is located on the side farther from the container 20.

[0012] The container 20 may be any type as long as it can contain the contents to be poured through the pouring outlet member 10. The type of container 20 is not particularly limited, and may be a packaging bag, a tube, a bottle, or the like. The container 20 may be rigid or flexible. If the container 20 is flexible, it can be easily folded during or after pouring.

[0013] When the container 20 is a packaging bag, the base end 11a of the spout member 10 may be weldable to the packaging bag. When the container 20 is a bottle or the like, the container 20 may be molded integrally with the spout member 10 using insert molding or the like. When the container 20 is a tube or the like, the spout member 10 may be molded separately from the container 20, or the spout member 10 may be molded integrally with the container 20.

[0014] 2, the spout member 10 generally includes a main body member 11 including a base end portion 11a, and an accessory member 13 including a tip end portion 13a. In the spout member 10 shown in the figure, tip end portion 13a is covered with a lid portion 17.

[0015] In addition, the spout member 10 of this embodiment has a screw 14 rotatably arranged within the flow path 12 of the main body member 11, and an operating portion 15 that enables the screw 14 to be operated from outside the main body member 11.

[0016] The screw 14 can rotate so as to propel the contents from the base end 11a side toward the tip end 13a side. The operating part 15 can rotate relative to the base end 11a to rotate the screw 14. The rotation axis 14a of the screw 14 extends along the axial direction A of the spout member 10.

[0017] The screw 14 in the illustrated example has blades 14b around the rotation shaft 14a. The shape of the blades 14b is not particularly limited, but it is preferable that they are formed in a spiral shape within a predetermined angle range relative to the rotation shaft 14a. The number of blades 14b is not particularly limited, and may be one or more. Furthermore, the blades 14b in the illustrated example are formed around the rotation shaft 14a over approximately two revolutions (720°). The angular range of the spiral is not particularly limited, and may be less than one revolution or more than one revolution.

[0018] One end of the rotating shaft 14a has a fixing portion 14c for fixing the screw 14 to the spout member 10. The fixing portion 14c may fix the screw 14 to the base end 11a side, but the fixing portion 14c in the illustrated example fixes the screw 14 to the tip end 13a side. Furthermore, the fixing portion 14c may fix the screw 14 to the spout member 10 at the rotating shaft 14a, but the fixing portion 14c in the illustrated example fixes the screw 14 to the spout member 10 at the blade portion 14b.

[0019] The above-described main body member 11 can have a structure similar to that of a general spout in that it has a tubular portion 11b that protrudes from the base end 11a toward the tip end 13a. In the illustrated example, the tubular portion 11b is substantially cylindrical, and the base end 11a has an outer diameter larger than that of the tubular portion 11b.

[0020] The base end 11a in the illustrated example has a so-called boat shape. The boat-shaped base end 11a has both ends that protrude in two opposite directions from the center portion having the cylindrical portion 11b. In the illustrated example, the two opposite directions are the left and right directions in FIG. 1. The opening of a packaging bag can be welded around the periphery of the base end 11a by aligning the two opposite directions of the both ends with the width direction of a container such as a packaging bag.

[0021] Although not particularly shown, the outer shape of the main body member 11 may be a cylindrical shape having a substantially uniform outer shape from the base end 11a to the tip of the cylindrical portion 11b. Also, although the base end 11a in the illustrated example includes a plurality of ribs 11f on the outer periphery, the outer surface of the base end 11a may be a flat surface without the ribs 11f. The shape of the base end 11a is not particularly limited, and may be a substantially cylindrical shape, a square tube shape, or the like.

[0022] The shape of the cylindrical portion 11b is not limited to a substantially cylindrical shape as long as the operating unit 15 can be rotatably mounted on the outer periphery thereof, and may be a polygonal cylindrical shape, etc. When the outer surface of the cylindrical portion 11b and the inner surface of the operating unit 15 are formed into a substantially cylindrical surface, the operating unit 15 can be easily rotated to any angle on the outer periphery of the cylindrical portion 11b.

[0023] A flow path 12 is formed inside main body member 11, extending from base end 11a to tip 11c of tubular portion 11b. Flow path 12 extends along axial direction A of spout member 10. Flow path 12 has a first opening 12a on the side of base end 11a of spout member 10, and a second opening 12b on the side of tip end 13a of spout member 10.

[0024] In the illustrated example, first opening 12a is a single opening, which facilitates receiving contents from the container into flow channel 12. In addition, the second opening 12b is divided into a plurality of openings, making it easier to adjust the amount of content dispensed from the flow path 12.

[0025] The illustrated operating portion 15 has an elastically deformable locking portion 15a relative to a reinforcing portion 15b reinforced by reinforcing ribs 15c. Locking portion 15a and reinforcing portion 15b are partially separated by a notch 15d. Furthermore, an engagement groove 15e capable of receiving an engagement protrusion 11e of main body member 11 is formed on the inner surface of operating portion 15 to rotatably hold operating portion 15 relative to base end portion 11a.

[0026] To attach the operating part 15 to the outer periphery of the main body member 11, the locking part 15a is deformed in a direction away from the cylindrical part 11b of the main body member 11, and then, when the fitting protrusion 11e of the cylindrical part 11b is received in the fitting groove 15e, the locking part 15a is returned in a direction approaching the cylindrical part 11b. The fitting protrusion 11e extending circumferentially around the axial direction A restricts the displacement of the operating part 15 along the axial direction A.

[0027] The illustrated operating unit 15 has a structure for realizing a tamper-proof function (tamper evidence, pilfer proof). The illustrated tamper-proof structure 16 has a ring portion 16a arranged around the tubular portion 11b and a bridge portion 16b that connects the ring portion 16a to the operating unit 15. A gap 16c is secured between the operating unit 15 and the ring portion 16a, except for the portion where the bridge portion 16b is arranged.

[0028] In the illustrated example of the tamper-proof structure 16, multiple bridge portions 16b are arranged at intervals around a portion of the circumference of the ring portion 16a. The operating portion 15, the ring portion 16a, and the bridge portion 16b may each be formed from a different material. In the illustrated example, the ring portion 16a and the bridge portion 16b are integrally formed from the same material as the operating portion 15.

[0029] Although not shown, the ring portion 16a has a rotation stopper to prevent it from rotating beyond a predetermined range relative to the outer periphery of the cylindrical portion 11b. One example of the rotation stopper function is a structure in which a restricting protrusion 16d formed on the inner periphery of the ring portion 16a is housed within a restricting recess (not shown) formed on the outer periphery of the cylindrical portion 11b. The restricting protrusion 16d hits a step at the end of the restricting recess, thereby preventing the ring portion 16a from rotating.

[0030] Bridge portion 16b can be broken when operating portion 15 is rotated around cylindrical portion 11b. For example, when the above-described restricting protrusion 16d hits a step at the end of the restricting recess, preventing further rotation of ring portion 16a, and operating portion 15 is then operated in the rotational direction, bridge portion 16b breaks. When bridge portion 16b breaks, gap 16c between operating portion 15 and ring portion 16a is secured around the entire circumference of ring portion 16a, and ring portion 16a separates from operating portion 15. Irreversible breaking of bridge portion 16b achieves a tamper-proof function.

[0031] If the operating unit 15 has the tamper-proof structure 16, the operating unit 15 becomes rotatable to any angle after the tamper-proof structure 16 undergoes an irreversible change such as breakage. Note that if the tamper-proof structure 16 is omitted, the operating unit 15 may be rotatable to any angle from the beginning. Here, an arbitrary angle may be an angle exceeding one rotation (360°). Conversely, in a state in which the tamper-proof structure 16 has not undergone any change such as breakage, the operating unit 15 may be capable of displacement at a small angle less than one or half rotation (180°). The range of displacement of such a small angle can be adjusted, for example, by the dimensions of the restricting recess described above.

[0032] The distal end portion 13a in the illustrated example is integrated with the operating portion 15. This allows the distal end portion 13a to rotate relative to the proximal end portion 11a in accordance with the rotation of the screw 14. Specifically, the operating portion 15 is included in a part of the accessory member 13 described above.

[0033] 2, when the screw 14 is fixed to the operating unit 15 at the tip portion 13a side, the screw 14 and the tip portion 13a rotate at the same rotational speed in response to the rotation of the operating unit 15. As a result, the bearing corresponding to the rotation of the screw 14 only needs to be structured to be arbitrarily rotatable between the operating unit 15 and the main body member 11, and the structure for holding the rotatable screw 14 can be simplified.

[0034] The tip portion 13a of the spout member 10 includes a tip tubular portion 13b that surrounds the periphery of the tip ring 14d of the screw 14, and a tip protrusion 13c that has the above-mentioned second opening 12b. The tip ring 14d protrudes from the fixed portion 14c toward the tip portion 13a in the axial direction A. The tip ring 14d has an opening inside so as to connect the flow path 12 between the inside of the tubular portion 11b and the inside of the tip tubular portion 13b.

[0035] In the illustrated example, the tip protrusion 13c is formed with partitions 13d that separate the second openings 12b. The partitions 13d are arranged at intervals in the circumferential direction. The number of partitions 13d is not particularly limited, but may be, for example, 2 to 6. The opening area of the second openings 12b can also be adjusted depending on the dispensing speed of the contents.

[0036] The direction in which the contents are poured out from second opening 12b is diagonal or horizontal to axial direction A. Even if the tip surface of tip protrusion 13c is exposed to the outside of lid portion 17, second opening 12b is covered under lid portion 17. From the viewpoint of ensuring that the pouring direction of second opening 12b does not deviate from axial direction A, it is also possible to have only one second opening 12b formed in tip portion 13a.

[0037] A lid portion 17 is attached to the tip protrusion 13c. The lid portion 17 in the illustrated example has a cylindrical side portion 17a that surrounds the tip tube portion 13b and a top surface portion 17b that covers the tip protrusion 13c. A third opening 17c that fits into the tip protrusion 13c is formed in the top surface portion 17b. The third opening 17c is a hole that penetrates the top surface portion 17b. The lid portion 17 in the illustrated example has a cylindrical side portion 17a. The shape of the lid portion 17 is not particularly limited, and it may be a square tube shape, for example.

[0038] In the illustrated example, the lid portion 17 has a retaining portion 13e formed on the outer periphery of the tip tube portion 13b that prevents the side portion 17a from being removed, so that the lid portion 17 will not come off the tip portion 13a with a normal level of external force. The force required to remove the lid portion 17 can be adjusted by the protruding height and strength of the retaining portion 13e, but the structure of the illustrated example is designed so that the lid portion 17 can be used without being removed from the tip portion 13a.

[0039] Specifically, when lid 17 is pulled and displaced along axial direction A until third opening 17c is released from tip protrusion 13c, space 12c through which the contents can flow is formed between second opening 12b and third opening 17c, making it possible to pour the contents in flow path 12 from third opening 17c.

[0040] After the contents have been dispensed, third opening 17c is closed by pushing lid 17 along axial direction A until third opening 17c engages with tip protrusion 13c. Even if the contents remain in space 12c between second opening 12b and lid 17, they can return to the container through second opening 12b, but are prevented from being discharged through third opening 17c.

[0041] The lid 17 in the illustrated example can be maintained attached to the tip 13a of the spout member 10 when the flow path 12 is opened or closed via the third opening 17c. This makes it possible to prevent the lid 17 from being lost, etc.

[0042] Although not particularly shown, the mechanism for controlling the opening and closing of second opening 12b of flow channel 12 is not limited to the illustrated example, and various mechanisms can be adopted. For example, a cap or the like that can be separated from tip end portion 13a may be used as lid portion 17. The cap or the like can be detachably attached to tip end portion 13a by fitting, screws, or the like.

[0043] 4 and 5 show an example of a container 30 with a spout of this embodiment. Fig. 4 is a front view before opening, and Fig. 5 is a front view illustrating the state of use after opening. The container 30 with a spout of this embodiment is a container 20 equipped with the spout member 10 described above. The container 20 in the illustrated example is a packaging bag 21.

[0044] The periphery of the packaging bag 21 is sealed with a sealed portion 22. The sealed portion 22 surrounds a storage portion 23 consisting of an unsealed portion. The storage portion 23 is filled with the contents. There are no particular limitations on the method for filling the contents, but a filling opening may be provided in part of the sealed portion 22, and the filling opening may be sealed and closed after the contents have been filled. The contents may be filled into the packaging bag 21 before the base end 11a is joined, and then the spout member 10 may be joined to the position where the filling opening was. With only the main body member 11 joined to the packaging bag 21, the contents may be filled through the tubular portion 11b, and then the screw 14, operating portion 15, etc. may be attached to the main body member 11.

[0045] The orientation of the spout member 10 when the contents are contained in the container 20 can be changed depending on the state of use, etc., but when pouring the contents, the contents are poured out according to gravity, so it is preferable to position the container 20 above the spout member 10. When storing, transporting, or displaying the container 20 containing the contents, it is preferable to position the container 20 below the spout member 10.

[0046] When pouring the contents, the tip 13a of the spout member 10 may be facing downward, diagonally downward, or sideways. When not pouring the contents, the tip 13a of the spout member 10 may be facing upward, diagonally upward, or sideways. To facilitate pouring of the contents when the viscosity of the contents is high, it is preferable that the contents can be poured with the tip 13a of the spout member 10 facing downward.

[0047] In the illustrated example of a container with a spout 30, the container 20 is a packaging bag 21 having a bottom 24, and the spout member 10 is disposed at an angle to the bottom 24. Furthermore, a hanging hole 25 is disposed on the side of the bottom 24 opposite the spout member 10. By passing a hanging tool (not shown) such as a hook through the hanging hole 25, the orientation of the container with a spout 30 can be maintained with the spout member 10 facing downward.

[0048] When opening the spout-equipped container 30, if the spout member 10 has the tamper-proof structure 16, the spout member 10 is opened to remove the tamper-proof structure 16. Furthermore, the lid portion 17 is removed or displaced to open the tip portion 13a of the spout member 10. By rotating the screw 14 via the operation of the operation portion 15, even highly viscous contents can be easily poured out.

[0049] In the illustrated example of spout member 10, base end portion 11a and cylindrical portion 11b are formed as an integrated main body member 11. Although not specifically shown, main body member 11 may be formed as a combination of two or more members. Furthermore, in the illustrated example of spout member 10, tip portion 13a and operating portion 15 are formed as an integrated accessory member 13. Although not specifically shown, accessory member 13 may be formed as a combination of two or more members.

[0050] The spout member 10 of the embodiment may be used to transfer the contents filled in the container 20 into another container. The other container is not particularly limited, but may include a container body capable of accommodating the contents and a neck member protruding from the container body. The container body to be transferred is not particularly limited, but may be a packaging bag, a tube, a bottle, or the like.

[0051] The spout member 10 of the embodiment may be used for consuming the contents filled in the container 20 according to the purpose of the contents. For example, if the contents are liquids such as daily necessities, the required amount can be dispensed by operating the operating unit 15 when using detergent for cleaning or laundry, shampoo or conditioner for washing hair, or seasoning for cooking. Even in fields where bottle containers have traditionally been used to store contents until they are used, pouch containers can be used instead.

[0052] Since the operating part 15 is structured to rotate the screw 14 according to the rotation angle, no external energy source such as electricity is required, and even consumers can operate it intuitively. When the contents are highly viscous, stopping the rotation of the operating part 15 can prevent the contents from pouring out even if the open spout member 10 is facing downward.

[0053] For example, when using shampoo or conditioner in a bathroom, a cantilevered member attached to the bathroom wall can be passed through the hanging hole 25 to prepare a container 30 with a spout. Examples of cantilevered members include a hook, a towel rack, a shower hook, etc. Even with eyes closed while washing hair, the user can easily switch between dispensing and stopping the dispensing of the contents by operating the operating unit 15.

[0054] A looped string may be passed through the hanging hole 25, and the looped portion of the string may be hung on, for example, a shower head placed on a shower rack. Attaching a string to the hanging hole 25 allows the spout-equipped container 30 to be hung on a cantilevered member whose cross-sectional shape is larger than the hanging hole 25, or on a member that is not cantilevered. For example, it also makes it easier to take shampoo or conditioner out of the spout-equipped container 30 while water is being poured from the shower head.

[0055] Highly viscous fluids such as shampoo and conditioner take a long time to dispense by natural falling, making it difficult to dispense the desired amount. By suspending the container 20 and positioning it so that the spout member 10 faces downward, the contents tend to accumulate in the internal flow path 12. By rotating the screw 14 within the flow path 12, the contents are pushed out toward the tip 13a.

[0056] Closing the lid 17 stops the dispensing of the contents regardless of whether the operating part 15 is rotated. Since the lid 17 is opened and closed simply by sliding it relative to the tip 13a, the act of closing the lid 17 can also be performed quickly. The container 30 with a spout may be left hanging while the contents are not being removed. If the contents are highly viscous, spillage of the contents is suppressed for a short period of time even when the lid 17 is open, and spillage of the contents is prevented for a long period of time when the lid 17 is closed.

[0057] By leaving the spout-equipped container 30 with the spout member 10 facing downward, even if the remaining amount in the container 20 is small, time can be gained for the contents to flow down from the hanging container 20 toward the spout member 10. This makes it easier to dispense the contents to the last drop.

[0058] The shape of the screw 14, the pitch (angle) of the blade portion 14b, etc. can be changed as appropriate to adjust the discharge amount relative to the amount of rotation of the operating portion 15. In the illustrated example, the screw 14 is a separate part from the main body member 11 and the accessory member 13, so screws 14 with different designs can be attached depending on the type, viscosity, etc. of the contents. For example, multiple specifications may be prepared in which the parts other than the screw 14 are common and only the screw 14 has different designs.

[0059] In the illustrated example, the operating unit 15 has reinforcing ribs 15c protruding from multiple locations in the circumferential direction, which not only function as an anti-slip function when rotating, but also serve as marks for identifying the amount of rotation of the operating unit 15. The position of the reinforcing ribs 15c may be recognized visually with the eyes, or, if the eyes are closed, the position of the reinforcing ribs 15c may be recognized by the sense of touch of the hand.

[0060] In the illustrated example, the hanging hole 25 is located at either the left or right corner of both the left and right sides 24a of the bottom 24. In a self-standing packaging bag 21, a bottom member folded in two in a substantially Λ shape is placed between the front and rear body members, and the seals on both the left and right sides 24a in the width direction are formed wider than the seal on the central portion 24b. When the folded bottom member is opened, the installation area of the bottom 24 expands, allowing the packaging bag 21 to stand on its own. Although not particularly shown, it is also possible to place the hanging hole 25 in the central portion 24b of the bottom 24. The hanging holes 25 may be formed in two or more locations.

[0061] While the present invention has been described above based on preferred embodiments, the present invention is not limited to the above-described embodiments and various modifications are possible without departing from the spirit of the present invention. Modifications include addition, substitution, omission, and other changes to components in each embodiment.

[0062] The contents of container 20 are not limited to the above examples, but may include liquids, solids such as powders and granules, viscous materials, liquids, or mixtures thereof. Examples of liquid contents include liquid cosmetics, liquid detergents, liquid seasonings, and liquid medicines. Examples of powders and granules, i.e., solid contents, include salt, sugar, pepper, granular seasonings, and powdered detergents.

[0063] The packaging bag 21 for the container 20 can be in various forms, such as a stand-up pouch, a three-side sealed bag, a four-side sealed bag, or a gusset bag. The packaging bag 21 may be made of a flexible packaging film or sheet. The packaging film or sheet can be made primarily of, for example, various synthetic resins, paper, metal foil, or two or more of these.

[0064] Examples of packaging films include single-layer films, multilayer films, and laminate films. Examples of resin films contained in packaging films include films mainly made of resins such as polyolefin, polyamide, and polyester. The packaging film may have a metal foil such as aluminum foil, a metal vapor-deposited layer such as aluminum, an inorganic vapor-deposited layer such as ceramic, or a gas barrier resin layer such as an ethylene-vinyl alcohol copolymer.

[0065] Examples of polyolefins that can be used for packaging films include polyethylene and polypropylene. Examples of polyamides include nylon. Examples of polyesters include polyethylene terephthalate. The packaging film may have a uniaxially or biaxially stretched resin film as a substrate.

[0066] The packaging film may have a resin layer such as low-density polyethylene, linear low-density polyethylene, ethylene-vinyl acetate copolymer, or polypropylene as a sealant. The sealant is provided on at least the inner surface of the packaging film. Packaging bag 21 can be produced by placing multiple packaging films together with the sealants facing each other and welding them together.

[0067] The manufacturing method of the packaging film is not particularly limited, but examples of film-forming and laminating methods include extrusion molding, cast molding, dry lamination, extrusion lamination, and co-extrusion. To improve adhesive strength, a coating film of an adhesive, an anchor agent, or the like, or a surface treatment such as corona treatment, plasma treatment, or ozone treatment may be provided between layers. The coating film or surface treatment between layers may be provided on the surface of any layer.
