Japanese Patent Application Publication No. 2014-80218

In the spout of Patent Document 1, a plurality of ventilation holes are formed at intervals in the circumferential direction in a movable member, and a spouting tube is arranged on the inner peripheral side of the ventilation holes. Air discharged from the refillable container in place of the liquid supplied from the refillable container is discharged to the outside from the outside of the spout tube through the ventilation hole. Therefore, unless the volume of the refillable container is reduced in accordance with the discharge of the liquid, a negative pressure will be generated inside the refillable container, causing a problem in which it will be difficult to pour out the liquid.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a spout for dispensing and a container with a spout for dispensing with which contents such as liquid can be easily poured out.

In order to solve the above problems, the present invention includes a spout main body including a spouting cylinder part, and a movable member that is movable along the axial direction of the spouting cylinder part, and the spouting cylinder part The movable member has a slit that opens a content flow path along the axial direction, and the movable member includes a closing portion that closes the content flow path in the slit, and a closing portion that extends along the axial direction inside the spouting cylinder portion. a tubular portion having an air flow path, the air flow path having an air outlet that opens laterally from the axial direction on the base end side, and the spout body having a cylindrical shape that covers the air outlet. By moving the movable member from the distal end side to the proximal end side with respect to the spouting cylinder section, the closing section retracts from the distal end side of the slit and the content flow path is closed. Provided is a spout for spouting, which is open and the air outlet opens to the outside of the covering part.

The movable member may have an engaging portion that engages with the spout body when the movable member is moved from the distal end side to the proximal end side with respect to the spouting cylinder portion.
The movable member is between a closed position where the closing part closes the slit and an open position where the content channel is opened by moving from the distal end side to the proximal end side with respect to the spouting cylinder part, They may be mutually switchable.
The spout body may include a guide portion that guides the movable member to slide in the axial direction.

The spout may include a cap that covers the distal end side of the spout cylinder, and the cap may prevent movement of the movable member from the distal end side to the proximal end side.
The spout main body may have an attachment part for a main body container that accommodates contents, and the spouting cylinder part may protrude from the attachment part toward the distal end side.
Further, the present invention provides a container with a spout for pouring, characterized by comprising the spout for pouring and a body for accommodating contents.

According to the present invention, since the air outlet, which is the outlet of the air flow path extending inside the spouting cylinder, opens laterally, the air outlet is closed together with the content flow path in the closed position. Furthermore, by moving the movable member from the closed position on the distal end side to the open position on the proximal end side, the content channel opens to the outside and the air outlet opens into the main container. Since the content flow path and the air flow path are partitioned by the tubular part and the covering part, the content such as liquid can be easily poured out.

Hereinafter, the present invention will be described based on preferred embodiments and with reference to the drawings.

FIGS. 1 to 7 illustrate spouts according to embodiments. FIG. 1 shows a state in which a cap 40 is attached to the spout 10 for dispensing. FIG. 2 shows the dispensing spout 10 in the closed position. FIG. 3 shows the dispensing spout 10 in its open position. 4 and 5 show cross-sectional views of the spouted container 11 in the closed position. 6 and 7 show a cross-sectional view of the spouted container 11 in the open position.

As shown in FIGS. 1 to 3, the spout 10 of the embodiment includes a spout main body 20 including a spout cylinder part 23, and a movable spout body 20 that is movable from the distal end side to the base end side of the spout cylinder part 23. A member 30 is provided. Further, the spout 10 of the embodiment includes a cap 40 that covers the tip of the spout cylinder 23.

In addition, in this specification, the tip side is the side facing the spout 10 from the body part 14 of both directions along the central axis of the spout cylinder part 23. Moreover, the proximal end side is the side that goes from the pouring spout 10 toward the body section 14 along the central axis. Moreover, in the following description, the radial direction and the circumferential direction with respect to the central axis of the pouring cylinder part 23 may be simply referred to as the radial direction and the circumferential direction, respectively. That is, the radial direction is a direction perpendicular to the central axis. Further, the circumferential direction is a direction surrounding the central axis. Further, the direction along the central axis may be referred to as an axial direction.

4 to 7, a part of the main container 12 to which the pouring spout 10 is attached is also illustrated. The spout-equipped container 11 is constructed by attaching the spout 10 to the mouth 13 of the main container 12. The main container 12 has a body 14 that accommodates contents. A bottom portion (not shown) may be provided below the body portion 14 . The main container 12 may be self-supporting, or may be a container that is not self-supporting, such as a flat bag.

The spout main body 20 roughly includes an attachment part 21 for the main body container 12 and a spouting cylinder part 23 protruding from the attachment part 21 toward the distal end side.
Furthermore, the movable member 30 roughly includes a base portion 31 that is attached to the spouting cylinder portion 23 and an engaging portion 32 that is engaged with the attachment portion 21.

As shown in FIG. 1, the cap 40 roughly includes a top portion 41 that is attached to the spouting tube portion 23, and a locking portion 42 that is locked between the attachment portion 21 and the base portion 31. Although the top portion 41 in the illustrated example is circular, it can be designed in various shapes such as a polygon such as a quadrangle, an ellipse, and the like. The shape, structure, etc. of the top portion 41 are not particularly limited as long as they are compatible with the distal end side of the pouring tube portion 23.

The locking portion 42 is locked in a notch 32c formed between the base 31 of the movable member 30 and the upper edge 21c of the attachment portion 21. By attaching the cap 40, the movable member 30 is prevented from moving from the distal end side to the proximal end side. The illustrated cap 40 has locking portions 42 facing each other in two positions in the circumferential direction, and is elastically deformed from the inside to the outside in the radial direction, thereby locking the locking portions 42 to the mounting portion 21. is canceled. The structure for fixing the cap 40 to the spout main body 20 is not limited to locking using elastic deformation of an arm-shaped member. good.

In the case of the illustrated spout body 20, the upper edge 21c of the attachment portion 21 is formed in the shape of a rib whose thickness gradually decreases toward the distal end. Therefore, when the locking portion 42 of the cap 40 is pinched from the outside of the upper edge 21c, the upper edge 21c is unlikely to deform inward. Moreover, when releasing the locking of the locking part 42, it is easy to put a finger on the inside of the locking part 42 along the outer curved surface of the upper edge part 21c.

As shown in FIG. 2, when the cap 40 is removed from the spout 10, the movable member 30 can be moved from the distal end to the proximal end with respect to the spout cylindrical portion 23. The gripping recess 21b formed on the side surface of the mounting portion 21 is used as necessary when gripping the spout 10 when attaching the spout 10 to the main container 12, removing the cap 40, etc. can do. In the illustrated example of the movable member 30, the engaging portions 32 are formed at two positions in the circumferential direction on different sides from the cutout portion 32c.

A slide recess 22 is formed on the side surface of the attachment portion 21, into which the engagement portion 32 can enter when the movable member 30 moves. An engagement convex portion 32a (see FIGS. 5 and 7) formed on the inner surface of the engagement portion 32 can engage with an engagement recess 22a formed within the slide recess 22. The slide recess 22 is formed in the axial direction with respect to the engaging part 32, and serves as a guide part that guides the movable member 30 to slide in the axial direction.

The reinforcing rib 32b formed between the base portion 31 and the engaging portion 32 is inserted into the insertion groove 22b when the movable member 30 moves. The reinforcing rib 32b may have a plate shape having a substantially uniform wall thickness. The depth at which the reinforcing rib 32b is inserted into the insertion groove 22b may be adjusted depending on the limit to which the movable member 30 can be moved toward the proximal end. The insertion groove 22b is formed in the axial direction with respect to the reinforcing rib 32b, and serves as a guide portion that guides the movable member 30 to slide in the axial direction.

The pouring cylinder part 23 has a shape that projects from the attachment part 21 toward the distal end side. Thereby, a space in which the movable member 30 functions on the attachment part 21 is neatly secured on the outside of the spouting cylinder part 23 in the radial direction. The overall shape of the illustrated spouting cylinder part 23 except for the slit 26 is approximately cylindrical, but the shape of the spouting cylinder part 23 is not particularly limited, and may be a square cylinder such as a triangular cylinder or a square cylinder. It may also be shaped like an elliptical cylinder.

As shown in FIGS. 2 and 3, the spouting cylinder portion 23 has a slit 26 that opens the content flow channel 24 along the axial direction. Furthermore, the movable member 30 has a closing portion 33 that closes the content flow channel 24 at the slit 26 . The illustrated pouring cylinder portion 23 has slits 26 at two locations in the circumferential direction, and also has content flow channels 24 at two locations different from the positions of the slits 26 in the circumferential direction.

The opening shape of the slit 26 is approximately H-shaped in plan view when viewed from the tip side. Note that the slit 26 in the illustrated example has a shape in which the pouring cylinder portion 23 is divided into two halves. The slit 26 has at least a portion that opens from the inside of the pouring cylinder portion 23 in the radial direction toward the outside. Even if the slit 26 is not open at the distal end of the dispensing cylinder 23, it is possible to pour out the contents from the slit 26.

The slit 26 is open not only at the side of the spouting cylinder part 23 but also near the central axis. Therefore, the contents discharged from the two content flow channels 24 facing each other via the central axis can merge near the central axis. Further, when attaching the movable member 30 to the spout body 20 from the distal end side, the closing portion 33 can be inserted from the distal end side of the slit 26. Note that the shape of the slit 26 is not particularly limited, and can be arranged at one or more arbitrary positions in the circumferential direction of the spouting cylinder part 23.

The movable member 30 has a tubular part 34 inside the pouring cylinder part 23. An air flow path 35 is formed inside the tubular portion 34 and extends along the axial direction. The illustrated movable member 30 includes tubular portions 34 having air flow paths 35 at two locations on both sides of the content flow path 24 along the central axis. That is, both left and right sides of the above-described substantially H-shaped slit 26 are regions where the tubular portion 34 is arranged.

Note that the ranges of the closing portion 33 and the tubular portion 34 do not necessarily need to be strictly distinguished. Of the tip side portion of the tubular portion 34 where the movable member 30 overlaps the position of the slit 26 in the axial direction, the outer peripheral portion excluding the inside surrounding the air flow path 35 serves as a closing portion 33 that closes the side portion of the slit 26. can function. That is, the same part included in the movable member 30 may serve both the function of the closing part 33 and the function of the tubular part 34.

A guide groove 25 along the axial direction is formed on the surface of the spouting cylinder part 23 on the slit 26 side so as to guide the movement of the movable member 30. The guide grooves 25 are arranged in pairs so as to sandwich the tubular portion 34 therebetween. That is, the guide grooves 25 are provided at two locations for each of the two tubular portions 34, for a total of four locations.

The guide groove 25 is formed in the axial direction with respect to the tubular portion 34, and serves as a guide portion that guides the movable member 30 to slide in the axial direction. Thereby, when the movable member 30 is displaced along the axial direction, displacement in either the left or right direction is suppressed. That is, the displacement of the movable member 30 is mainly axial displacement, and radial or circumferential displacement is less likely to occur.

As shown in FIGS. 3 and 4, a brake convex portion 23a that can be coupled to a brake concave portion 33a of the movable member 30 is formed on the distal end side of the pouring cylinder portion 23. The braking convex portion 23a projects inward in the radial direction from the top surface portion 23b of the spouting cylinder portion 23. Further, the brake recess 33a is formed on the distal end side of the closing portion 33 at a position in contact with the top surface portion 23b. When an external force is applied to move the movable member 30 from the distal end to the proximal end against the coupling force between the braking convex portion 23a and the braking concave portion 33a, the braking is performed due to elastic deformation of the spouting cylinder portion 23 and the closing portion 33, etc. The coupling between the convex portion 23a and the brake recess 33a is released, and the movable member 30 becomes movable.

In addition, although the braking convex portion 23a and the braking recess 33a in the illustrated example are provided at a position facing the slit 26 inside the spouting cylinder portion 23, they may be provided at other positions such as outside the spouting cylinder portion 23. may be provided. In the case of the illustrated example, even if the closing part 33 is displaced within the slit 26 when the movable member 30 moves, the braking recess 33a is recessed, so the closing part 33 does not interfere with the slit 26 and can move smoothly. is possible. For example, when the opening width of the slit 26 is widened on the proximal end side, a braking convex portion may be provided on the movable member 30 side, and a braking concave portion may be provided on the spout body side.

As shown in FIG. 4, in the spout 10 of the embodiment, the spout body 20 and the main body container 12 are constructed from separate members. Specifically, a mounting cylinder portion 28 protrudes from the mounting portion 21 toward the proximal end around the mouth portion 13 that serves as a filling or pouring port of the main container 12 . The spout main body 20 is fixed to the main body container 12 by coupling the threaded portion 28 a on the inner surface of the mounting cylinder portion 28 with the threaded portion 13 a on the outer surface of the mouth portion 13 .

A mounting recess 21 a is formed inside the mounting portion 21 so as to avoid interference with the shoulder portion 15 of the main container 12 . The shoulder portion 15 is a portion that tapers from the body portion 14 toward the mouth portion 13. The mounting cylinder portion 28 is arranged within the mounting recess 21a. The spout main body 20 can be attached to the main body container 12 by aligning the position of the mounting cylinder part 28 with the mouth part 13 and coupling the threaded parts 13a and 28a. Further, the spout main body 20 can be removed from the main body container 12 by rotating the threaded portions 13a and 28a in the opposite direction from when they are attached.

In the main container 12, the structure of the body 14 including the content storage part is not particularly limited, and examples thereof include a bottle container, a pouch container, a tube container, and the like. When the main container 12 is a molded container such as a bottle container, the spout main body 20 may be integrated into the main container 12 as a part of the molded container. When the main container 12 is made of a rigid container such as a bottle container or a semi-rigid container, the main container 12 can also be made of a thick resin molded container, a metal container, a glass container, or the like.

Depending on the structure of the main container 12, the spout main body 20 can be attached to any of the mouth 13, body 14, and shoulder 15 of the main container 12. The method of attaching the attaching portion 21 to the main container 12 is not particularly limited, and examples thereof include fitting, engagement, adhesion, and the like. The adhesion may be by melting the material of the spout body 20 or the main body container 12, or by applying an adhesive.

When attaching the attachment part 21 to the pouch container, a pouch member such as a film or a sheet may be attached to the outer or inner surface of the attachment part 21. By having a sealant layer made of a thermoplastic resin and an adhesive layer on at least one side of the pouch member, the pouch member and the spout body can be joined together in addition to the joining between the pouch members. Examples of the pouch container include a standing pouch and a gusset container having a folded film on the side or bottom surface.

Examples of materials for molding molded containers such as bottle containers include various synthetic resins such as thermoplastic resins and thermosetting resins. Containers such as pouch containers, tube containers, and bottle containers may include a layer made of a material other than resin, such as metal, paper, inorganic compound, or organic compound. The container to be poured (not shown) is a container to which the contents are poured. The main container 12 may be a refill container for transferring the contents to a container to be poured. Examples of the container to be poured include a container to be refilled, a measuring container, and various other containers. The pouring spout 10 may be disposable, or may be replaced with the same type of main container 12 and used repeatedly.

The contents are not particularly limited, but fluids such as liquids, powders, and granules can be used. The types of contents are not particularly limited, and include beverages, foods, seasonings, cosmetics, pharmaceuticals, detergents, adhesives, household goods, industrial products, and the like. Liquid contents include beverages, seasoning liquids, detergents, medicines, and the like. The contents of the powder or granules may include salt, sugar, pepper, granular seasoning, powdered detergent, and the like.

The spout body 20, movable member 30, and cap 40 that constitute the pouring spout 10 can be molded from various synthetic resins such as thermoplastic resins and thermosetting resins. The pouring spout 10 of the embodiment can be constructed of two members, each including the spout body 20 and the movable member 30 as integrally molded products, and three members including the cap 40.

The spout body 20 may be assembled from two or more parts, the movable member 30 may be assembled from two or more parts, and the cap 40 may be assembled from two or more parts. Furthermore, by connecting at least two of the three members consisting of the spout main body 20, the movable member 30, or the cap 40 via a string-like connecting portion, each member is configured at the end of the connecting portion. It is also possible to create an integrally molded product.

As shown in FIG. 5, the air inlet 35a, which is the inlet of the air flow path 35, opens at the tip 34a of the tubular portion 34 in the axial direction. The air flow path 35 extends toward the proximal end along the axial direction inside the tubular portion 34 . At the base end side of the air flow path 35, the air flow path 35 is bent laterally from the axial direction, and the air outlet 35b opens on the side surface of the tubular portion 34. The air outlet 35b is an outlet of the air flow path 35. The proximal end portion 34b of the tubular portion 34 is closed without the air flow path 35 being opened.

The spout body 20 has a cylindrical covering portion 27 that covers the air outlet 35b. The covering portion 27 protrudes from the inside of the mounting cylinder portion 28 toward the proximal end in the mounting portion 21 . The covering portion 27 has a tunnel-shaped inner wall portion 27c having a distal opening 27a on the distal side and a proximal opening 27b on the proximal side. The covering portion 27 is formed in the axial direction with respect to the tubular portion 34, and serves as a guide portion that guides the movable member 30 to slide in the axial direction.

When attaching the movable member 30 to the spout body 20, the tubular portion 34 is supported by the attachment portion 21 by inserting the tubular portion 34 into the proximal opening 27b and moving it toward the proximal end along the inner wall portion 27c. Ru. In the closed position, the air outlet 35b is closed in contact with the inner wall 27c without being exposed to the proximal opening 27b.

As shown in FIG. 4, in the closed position where the closing portion 33 closes the slit 26, the movement of the movable member 30 is temporarily stopped by the actions of the brake convex portion 23a, the brake concave portion 33a, etc. described above. The positional relationship between the spout main body 20 and the movable member 30 in the closed position is stable until an external force is applied to release the coupling between the brake convex portion 23a and the brake concave portion 33a, as described above. Therefore, even if the spout 10 is attached to the mouth 13 of the main container 12, the spout 13 is tilted so that the contents are poured out from the body 14, and even if the mouth 13 is turned downward. The movable member 30 can maintain the closed position.

When the distal end side of the movable member 30 is pressed against the container to be poured from the main container 12, movement beyond the closed position becomes possible, and the coupling between the brake protrusion 23a and the brake recess 33a is released. Therefore, when the user wants to take out the contents from the main container 12, it is possible to start moving the movable member 30 without picking up and operating the spout main body 20 or the movable member 30. Even if the mouth portion 13 of the main container 12 is tilted or facing downward, the contents will not be poured out if the spout 10 is in the closed position, so the spout 10 can be easily approached to the container to be poured. can be done.

As shown in FIG. 6, when the movable member 30 moves from the distal end side to the proximal end side with respect to the spout body 20, the closing part 33 retreats from the distal end side of the slit 26, and the content channel 24 opens to the outside. into the open position. In the open position, the content channel 24 is opened through the slit 26 between the distal end side of the spouting cylinder part 23 and the distal end side of the closing part 33. When the spout 10 is in the open position with the mouth 13 of the main container 12 tilted or facing downward, the contents L can be poured into the container to be poured. When the main container 12 has a shoulder 15, the contents L may flow along the shoulder 15 from at least one side with respect to the central axis.

In the case of the illustrated spout 10, the slit 26 divides the spout cylinder 23 into two parts along a plane including the central axis of the spout cylinder 23, and the distal end side of the spout cylinder 23 is divided into two. The top surface portion 23b regulates the cross-sectional area of the content flow path 24. As a result, the flow of the contents L from both sides of the slit 26 via the contents flow channel 24 tends to concentrate near the center of the spouting cylinder part 23 along the central axis. Thereby, the flow of the contents L becomes stable, and the contents L can be more reliably poured into the container to be poured.

In the illustrated example, the closing portion 33 of the movable member 30 is located in the middle of the content channel 24 even in the open position. A pair of diversion slopes 33b facing each other in a V-shape are formed on the base end side of the closing portion 33. Thereby, even if the closing portion 33 is present in the content flow path 24, the flow of the content L is less likely to be disturbed. The diversion slope 33b in the illustrated example consists of two slopes arranged symmetrically with respect to a plane including the central axis. The diversion slope 33b may be one slope with a single flow, three or more slopes radially in the circumferential direction, or may be conical. The tip of the diversion slope 33b may be rounded.

Further, as shown in FIG. 7, in the open position, the displacement of the tubular portion 34 along the inner wall portion 27c of the covering portion 27 progresses, and the air outlet 35b escapes from the base end opening 27b. As a result, the air outlet 35b is exposed to the outside of the covering portion 27 and opens into the main container 12. As a result, the air A discharged from the container to be poured instead of the contents L flows into the main container 12 through the air flow path 35.

Since the air flow path 35 does not open toward the proximal end side in the axial direction, but opens toward the side of the tubular portion 34, it is difficult for the contents L to enter the air flow path 35. Furthermore, since the cross-sectional area of the content flow path 24 is larger than the cross-sectional area of the air flow path 35, it is difficult for the contents L to enter the air flow path 35. Furthermore, since the position of the air outlet 35b in the open position protrudes proximally in the axial direction compared to the position of the shoulder 15 of the main container 12, the contents L flowing along the shoulder 15 are transferred to the air outlet. It is difficult to reach 35b.

According to the pouring spout 10 of the embodiment, even if the main container 12 is a rigid container or a semi-rigid container that does not easily reduce its volume as the contents L is discharged, the volume of air is adjusted according to the decrease in the contents L. flows into the main container 12 from the container to be poured. Thereby, a pressure difference between the inside and outside of the main container 12 is less likely to occur, and the contents L are smoothly poured out from the main container 12.

As described above, pouring out of the contents L starts from the stage when the closing part 33 is retracted from the tip side of the slit 26. Furthermore, the inflow of air A is started when the air outlet 35b exceeds the base end opening 27b of the covering portion 27. Since the dispensing of the contents L from the main container 12 to the container to be poured and the inflow of the air A from the container to be poured into the main container 12 start at approximately the same time, the amount of inflow of the air A is equal to the amount of the contents L. can be changed in conjunction with the amount dispensed.

Furthermore, by moving the movable member 30 from the distal end side to the proximal end side with respect to the spouting cylinder part 23, the engaging convex part 32a of the movable member 30 engages with the engaging concave part 22a of the spout main body 20. , the movable member 30 is fixed in the open position. As a result, even if the movable member 30 is not kept in contact with the container to be poured at the open position, the movable member 30 does not return from the proximal side to the distal side, and the open position state is maintained.

However, also in the spout 10 of the embodiment, the position of the movable member 30 can be returned from the open position to the closed position by disengaging the engagement convex portion 32a and the engagement recess 22a. It is. In addition, the engagement of the engagement convex portion 32a in the engagement portion 32 is omitted, and the position of the movable member 30 in the open position is determined by the tubular portion relative to the guide groove 25 of the spouting cylinder portion 23 and the inner wall portion 27c of the covering portion 27. It may be maintained by a friction force of 34 or the like. Thereby, the position of the movable member 30 can be switched between the closed position and the open position.

For example, the open position is maintained only while the movable member 30 is in contact with the container to be poured, and when the movable member 30 is separated from the container to be poured, the movable member 30 moves from the proximal end to the distal end toward the closed position. It is also possible to adopt a configuration in which movement to the side is started. For example, the movable member 30 may be displaced toward the distal end by an action that occurs on the top surface portion 23b while the contents L flow down within the contents flow path 24. Further, when the movable member 30 is separated from the container to be poured, the movable member 30 may be displaced toward the distal end side by biasing from a spring or the like.

According to the dispensing spout 10 of the embodiment, the air flow path 35 extends inside the dispensing cylinder section 23 and the air outlet 35b opens to the side of the tubular section 34, so that the content channel does not flow in the closed position. 24 and the air outlet 35b are closed. Further, by moving the movable member 30 from the closed position to the open position, the content channel 24 opens to the outside and the air outlet 35b opens into the main container 12. Since the content flow path 24 and the air flow path 35 are partitioned by the tubular portion 34 and the covering portion 27, the content L such as liquid can be easily poured out.

Although the present invention has been described above based on the preferred embodiments, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention.

In the pouring spout 10 of the embodiment, the slide recess 22, the insertion groove 22b, the guide groove 25, the covering part 27, etc. serve as a guide part corresponding to the sliding movement of the movable member 30 along the axial direction. The moving direction of the movable member is not limited to a linear sliding movement along the axial direction, but may also be a spiral twisting movement using a screw or the like, an arcuate rotation movement using a hinge or the like, or the like.
