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

1 to 3 show the pouring member connection structure of the first embodiment. FIG. 1 shows a state in which a first container (not shown) having a pouring member 10 and a valve body 20 and a second container (not shown) having a receiving portion 30 are close to each other. In FIG. 2, the first engaging portion 23 of the valve body 20 and the second engaging portion 33 of the receiving portion 30 are engaged at the closing position where the pouring flow path 15 of the pouring member 10 is closed. Indicates the state. In FIG. 3, the first engaging portion 23 of the valve body 20 and the second engaging portion 33 of the receiving portion 30 are engaged at the open position where the pouring flow path 15 of the pouring member 10 is opened. Indicates the state.

Each figure is represented so that the central axis is in the vertical direction. The tip side of the first container or its constituent members is the side where the first container approaches the second container along the central axis at the time of pouring. Similarly, the tip end side of the second container or its constituent members is the side where the second container approaches the first container along the central axis at the time of pouring. On the contrary, the side along the central axis opposite to the tip side is called the base end side. When the first container and the second container are combined, the base end side of the first container corresponds to the tip end side of the second container, and the base end side of the second container corresponds to the tip end side of the first container.

Further, the radial direction and the circumferential direction with respect to the central axis may be simply referred to as the radial direction and the circumferential direction, respectively. That is, the radial direction is a direction orthogonal to the central axis. The circumferential direction is a direction that surrounds the central axis. Further, the direction along the central axis may be referred to as the axis direction. Examples of the central axis that serves as a reference for the pouring direction include the central axis of the pouring member 10, particularly the central axis of the pouring flow path 15.

The dispensing member connection structure can be suitably applied to refilling and refilling the contents from the first container to the second container. In particular, it is suitable when using contents in which liquid leakage during refilling or refilling is a problem, for example, when targeting printing inks, seasonings, pharmaceuticals, cosmetics, detergents, chemicals, paints, fuels, and the like. .. The fluid of the contents is not limited to liquids such as solutions and dispersions, but may be powders, granules and the like.

The dispensing member 10 includes an insertion portion 11 having a dispensing flow path 15 through which a fluid flows. The insertion portion 11 has a tubular shape along the central axis of the pouring flow path 15. The cross-sectional shape perpendicular to the axial direction of the insertion portion 11 is not particularly limited, and examples thereof include a circular shape, an elliptical shape, and a polygonal shape. Although not particularly shown, the insertion portion 11 may have a through hole for penetrating the flow path from the inside of the first container in the radial direction of the insertion portion 11 on the base end side of the tip end portion 12.

A tip opening 12a is opened in the tip 12 which is a portion on the tip side of the insertion portion 11. The planar shape of the tip opening 12a is not particularly limited, and examples thereof include a circular shape, an elliptical shape, and a polygonal shape. A peripheral edge portion 12b is formed on the inner side in the radial direction around the tip opening portion 12a of the tip portion 12. A pouring flow path 15 is opened in the base end portion 13 which is a portion on the base end side of the insertion portion 11. An accommodating portion (not shown) for accommodating the contents in the first container can be provided on the outer circumference of the insertion portion 11 or in the vicinity of the base end portion 13.

The valve body 20 is provided in the insertion portion 11 so as to be displaced in the axial direction with respect to the tip opening portion 12a. The valve body 20 has a main body 21 having a through hole 21a penetrating in the radial direction, a contact portion 22 facing the peripheral edge portion 12b of the injection member 10 on the tip end side of the main body 21, and the diameter of the contact portion 22. A first engaging portion 23 formed on the inner side in the direction is provided. The main body 21 of the illustrated example has a basket shape in which a plurality of through holes 21a are arranged in the circumferential direction and the axial direction, respectively.

The valve body 20 can switch between an open position for opening the pouring flow path 15 and a closing position for closing the pouring flow path 15 by displacement in the axial direction. The outer diameter of the contact portion 22 is smaller than the inner diameter of the insertion portion 11 in the pouring flow path 15. Therefore, when the valve body 20 is in the open position, the space inside the main body 21 of the valve body 20 is the space on the tip end side of the contact portion 22 from the through hole 21a through the radial outside of the contact portion 22. It communicates with.

On the inner surface of the insertion portion 11, a guide portion 14 that regulates the displacement of the valve body 20 in the axial direction is formed. In the illustrated example, the guide portion 14 has a ridge portion 14a extending in the axial direction and a groove portion 14b formed between the ridge portions 14a forming a pair. Further, the main body 21 of the valve body 20 has a rib 24 protruding radially outward from a position different from the through hole 21a. The rib 24 is fitted in the groove portion 14b of the guide portion 14.

Since the axial displacement of the rib 24 is guided along the guide portion 14, the valve body 20 can be displaced in the axial direction without being displaced in the circumferential direction of the insertion portion 11. Further, in the illustrated example, four ribs 24 are arranged at intervals of 90 ° in the circumferential direction of the valve body 20. The valve body 20 can maintain the displacement along the axial direction by forming a structure in which the rib 24 protrudes radially toward the inner surface of the insertion portion 11.

The fitting of the rib 24 to the groove portion 14b, the degree of friction, and the like may be adjusted so that the valve body 20 does not displace with respect to the injection member 10 only when an external force below a predetermined threshold value is applied. For example, at least one of the ridge portion 14a or the rib 24 may be elastically deformed so that a tightening force acts on the fitting.

The configuration of the guide portion that regulates the displacement of the valve body in the axial direction is not limited to the illustrated example, and for example, a combination of a protrusion portion provided on the outer periphery of the valve body 20 and a groove portion provided on the inner surface of the insertion portion 11. Alternatively, a combination of a groove provided on the outer periphery of the valve body 20 and a protrusion provided on the inner surface of the insertion portion 11 may be used. By extending the groove portion in the axial direction, the protrusion portion can be displaced along the axial direction. By lengthening the shape of the protrusion in the axial direction within a range in which the length of the protrusion does not exceed the length of the groove, it is possible to stabilize the guidance of displacement along the groove.

The structure of the groove portion formed in the insertion portion 11 or the valve body 20 is not limited to the groove portion 14b of the illustrated example, and various configurations can be adopted. For example, it may be a bottomed groove portion that does not penetrate the wall surface on which the groove portion is formed in the thickness direction, or a groove portion that penetrates the wall surface in the thickness direction. The extending direction of the groove may be parallel to the axial direction or may be inclined from the axial direction. The groove may be spiral in the circumferential direction so as not to exceed, for example, half a circumference. The cross-sectional shape of the groove is not particularly limited, and examples thereof include a semicircle, a U-shape, a V-shape, and a polygon.

Further, as a configuration of the guide portion that regulates the displacement of the valve body in the axial direction, a shaft portion extending in a rod shape or a columnar shape is provided on one of the members selected from the insertion portion 11 or the valve body 20, and the insertion portion 11 or the valve is provided. The other member selected from the body 20 may be provided with a guide hole into which the shaft portion is inserted. By extending the shaft portion in the axial direction, the member having the guide hole can be displaced along the shaft portion.

At the closing position, the contact portion 22 of the valve body 20 comes into contact with the peripheral edge portion 12b of the tip opening portion 12a of the insertion portion 11. As a result, a gap for collecting the injected fluid is less likely to occur between the tip portion 12 of the insertion portion 11 and the abutting portion 22 of the valve body 20. The contact portion 22 preferably continuously contacts the peripheral edge portion 12b over the circumferential direction of the tip opening portion 12a. It is preferable that at least one of the contact portion 22 or the peripheral edge portion 12b is elastically deformed by pressing and the two are in close contact with each other.

At the open position, the contact portion 22 of the valve body 20 is separated from the peripheral edge portion 12b of the tip opening portion 12a of the insertion portion 11. This makes it possible to inject the fluid from the insertion portion 11 toward the receiving portion 30. The surface in which the contact portion 22 and the peripheral edge portion 12b come into contact may be a plane perpendicular to the axial direction, an annular surface extending in the circumferential direction, or a tapered surface inclined with respect to the axial direction.

The receiving portion 30 has an inserted portion 31 having an insertion hole 31a. The inserted portion 31 has a tubular shape along the central axis of the receiving portion 30. The cross-sectional shape perpendicular to the axial direction of the inserted portion 31 is not particularly limited, and examples thereof include a circular shape, an elliptical shape, and a polygonal shape. The insertion portion 11 is inserted into the insertion hole 31a. Therefore, when the pouring member 10 and the receiving portion 30 are combined, it is preferable that the central axis of the receiving portion 30 is coaxial or parallel to the central axis of the pouring member 10.

The insertion hole 31a has an opening 31b on the tip end side of the inserted portion 31. Although not particularly shown, the inserted portion 31 may have a through hole for penetrating the flow path in the radial direction. The fluid poured into the insertion hole 31a can be supplied into the second container through a through hole such as the opening 31b. A flange 34 may be provided on the outer periphery of the inserted portion 31 on the tip end side. An accommodating portion (not shown) for accommodating the contents in the second container can be provided on the outer circumference of the inserted portion 31 or in the vicinity of the flange 34. The wall surface of the accommodating portion may be joined to the flange 34.

A base portion 32 having a through hole 32a is formed on the base end side of the inserted portion 31. The base portion 32 is provided with a second engaging portion 33 that can engage with the first engaging portion 23. The second engaging portion 33 is arranged in the insertion hole 31a in the inserted portion 31. Further, the second engaging portion 33 extends from the base portion 32 to the tip end side of the receiving portion 30. The tip of the second engaging portion 33 may be arranged on the proximal end side of the opening 31b of the insertion hole 31a, or may project toward the distal end side of the opening 31b.

In the case of the illustrated example, the second engaging portion 33 has an engaging convex portion 33a protruding from the tip end side toward the outer side in the radial direction. Further, the first engaging portion 23 has an engaging concave portion 23a having a shape corresponding to the engaging convex portion 33a. The hollow portion 33b may be provided inside the second engaging portion 33. The hollow portion 33b may be opened only on the base end side of the inserted portion 31, may communicate with the insertion hole 31a on the radial outer side, or may be opened on the tip end side of the inserted portion 31. ..

The shape of the second engaging portion 33 is not particularly limited, and examples thereof include a tubular shape, a columnar shape, and a rod shape. The second engaging portion 33 may be provided with an engaging concave portion, and the first engaging portion 23 may be provided with an engaging convex portion. As shown in FIG. 1, in the closed position, the first engaging portion 23 is exposed to the tip opening portion 12a, and the second engaging portion 33 is arranged in the inserted portion 31. Therefore, as shown in FIG. 2, the first engaging portion 23 and the second engaging portion 33 can be engaged with the valve body 20 in the closed position.

The engagement between the first engaging portion 23 and the second engaging portion 33 has a strength capable of maintaining the engagement even if the valve body 20 is displaced between the open position and the closed position. The surface in which the first engaging portion 23 and the second engaging portion 33 come into contact may be a surface perpendicular to the axial direction, a surface extending in the circumferential direction, or a surface inclined with respect to the axial direction. .. When the first engaging portion 23 and the second engaging portion 33 are engaged, it is preferable that at least one of the engaging convex portion and the engaging concave portion is elastically deformed. As a result, when disengaging, it is necessary to apply an external force so as to restore the elastic deformation, so that a resistance force against the disengagement can be imparted.

When the insertion portion 11 is moved toward the base portion 32 of the receiving portion 30 while the first engaging portion 23 and the second engaging portion 33 are engaged, the valve body 20 is inserted as shown in FIG. It is displaced toward the base end portion 13 side of the portion 11 and becomes an open position. As a result, the contact portion 22 of the valve body 20 is separated from the peripheral edge portion 12b of the tip opening portion 12a of the insertion portion 11. When the valve body 20 is displaced to the open position, the pouring flow path 15 is communicated with the inside of the receiving portion 30 through the tip opening 12a.

When the valve body 20 is in the open position, the fluid poured from the first container into the insertion hole 31a through the injection flow path 15 is supplied to the second container side through the through hole 32a of the base portion 32. The power for pouring the fluid from the first container to the second container is not particularly limited, and examples thereof include gravity from the first container to the second container, pressure on the first container, and suction force of the second container. When the fluid is poured out according to gravity, the first container is placed above and the second container is placed below, but when using other power, the positional relationship between the first container and the second container is particularly limited. Not done. For example, the first container and the second container may be arranged substantially horizontally.

After pouring out the desired fluid, the insertion portion 11 is moved away from the base portion 32 of the receiving portion 30 while the first engaging portion 23 and the second engaging portion 33 are still engaged. As shown in 2, the valve body 20 is displaced toward the tip portion 12 of the insertion portion 11. As a result, the contact portion 22 of the valve body 20 comes into contact with the peripheral edge portion 12b of the tip opening portion 12a of the insertion portion 11, and the valve body 20 is in the closed position. Further, when the insertion portion 11 is moved away from the base portion 32 of the receiving portion 30, the engagement between the first engaging portion 23 and the second engaging portion 33 is released, and the valve body 20 in the closed position is provided. The insertion portion 11 is separated from the receiving portion 30.

That is, in a state where the first engaging portion 23 and the second engaging portion 33 are engaged at the closed position, the insertion portion 11 is moved to the tip side in the axial direction, whereby the first engaging portion 23 and the tip are engaged. The pouring flow path 15 is opened between the opening 12a and the opening. Further, in the state where the first engaging portion 23 and the second engaging portion 33 are engaged in the open position, the insertion portion 11 is moved to the base end side in the axial direction to form the first engaging portion 23. The pouring flow path 15 is closed between the tip opening 12a and the first engaging portion 23 and the second engaging portion 33 are disengaged.

Next, the injection member connection structure of the second embodiment will be described. 4 to 6 show the pouring member connection structure of the second embodiment. FIG. 4 shows a state in which the first container (not shown) having the dispensing member 110 and the valve body 120 and the second container (not shown) having the receiving portion 130 are close to each other. In FIG. 5, the first engaging portion 123 of the valve body 120 and the second engaging portion 133 of the receiving portion 130 are engaged at the closing position where the dispensing flow path 115 of the dispensing member 110 is closed. Indicates the state. In FIG. 6, the first engaging portion 123 of the valve body 120 and the second engaging portion 133 of the receiving portion 130 are engaged at the open position where the dispensing flow path 115 of the dispensing member 110 is opened. Indicates the state.

In the description of the second embodiment, the meanings of the distal end side, the proximal end side, the radial direction, the circumferential direction, the axial direction, and the central axis are the same as those of the first embodiment. Further, the insertion portions 11, 111, the tip portions 12, 112, the tip opening portions 12a, 112a, the peripheral portions 12b, 112b, the base end portions 13, 113, the dispensing flow paths 15, 115, and the valves of the dispensing members 10, 110 are provided. Main bodies 21, 121, contact portions 22, 122, first engaging portions 23, 123, receiving portions 31, 131, insertion holes 31a, 131a, openings 31b, of the bodies 20, 120, The basic configurations and functions of 131b, base portions 32, 132, second engaging portions 33, 133, flanges 34, 134, first container, second container, etc. are described in the first and second embodiments. It is almost common. Therefore, duplicate explanations may be omitted.

In the case of the dispensing member 110 of the second embodiment, the insertion portion 111 is the insertion cylinder portion 111a, which is a portion to be inserted into the inserted portion 131 of the receiving portion 130, and the base end portion 113 side of the insertion cylinder portion 111a. The extension cylinder portion 111b, which is a portion, and the flange 111c provided between the insertion cylinder portion 111a and the extension cylinder portion 111b are provided. The flange 111c projects outward in the radial direction of the insertion portion 111. In the first container provided with the injection member 110, the wall surface of the accommodating portion may be joined to the flange 111c. In the illustrated example, the outer diameter of the extension cylinder portion 111b is larger than the outer diameter of the insertion cylinder portion 111a, but the outer diameter of the extension cylinder portion 111b may be equal to or less than the outer diameter of the insertion cylinder portion 111a.

The valve body 120 is formed on the radial side of the main body portion 121 extending in the axial direction, the contact portion 122 facing the peripheral edge portion 112b of the injection member 110 on the tip end side of the main body portion 121, and the contact portion 122. It also includes a first engaging portion 123. The main body 121 of the illustrated example is formed in a single columnar shape extending along the central axis of the pouring flow path 115. A contact portion 122 and a first engaging portion 123 are formed at the end portion on the tip end side of the main body portion 121, and a ring-shaped base end portion 125 is formed at the end portion on the base end side of the main body portion 121. There is.

A side plate portion 124 is formed on the outer periphery of the main body portion 121 so as to project in a plate shape on the outer side in the radial direction. A plurality of side plate portions 124 are formed in the circumferential direction of the main body portion 121. The number of side plate portions 124 is not particularly limited, but in the illustrated example, four side plate portions 124 are arranged at intervals of 90 ° in the circumferential direction. The plurality of side plate portions 124 can be displaced in the axial direction without the valve body 120 being displaced in the radial direction by the sliding portion 124a on the outer side in the radial direction coming into contact with the inner surface of the insertion portion 111. .. Around the main body 121, a space is secured between the side plates 124 to allow fluid to flow. The valve body 120 can maintain the displacement along the axial direction by forming a structure in which the side plate portion 124 protrudes radially toward the inner surface of the insertion portion 111.

It is also possible for the valve body 120 to rotate in the circumferential direction of the insertion portion 111 when the valve body 120 is displaced in the axial direction. In the illustrated example, from the insertion cylinder portion 111a to the extension cylinder portion 111b, the inner diameter of the insertion portion 111 is a smooth cylindrical surface that is substantially constant, and the dimensions from the main body portion 121 to the sliding portion 124a are substantially constant in each side plate portion 124. Therefore, even if the valve body 120 rotates by an arbitrary angle in the circumferential direction, the displacement of the main body 121 in the radial direction of the insertion portion 111 can be suppressed.

The contact portion 122 has a shape protruding radially outward from the outer circumference of the main body portion 121 in a flat plate shape. Since the outer diameter of the contact portion 122 is smaller than the inner diameter of the insertion portion 111 in the injection flow path 115, the radial outside of the contact portion 122 can be a part of the flow path. The tip portion 112 of the insertion portion 111 has a fitting recess 112c that fits with the contact portion 122. The cross-sectional shape of the contact portion 122 and the fitting recess 112c in the plane perpendicular to the axial direction of the insertion portion 111 is circular. As a result, even if the valve body 120 rotates by an arbitrary angle in the circumferential direction, the contact portion 122 can be fitted into the fitting recess 112c.

The receiving portion 130 has through holes 132a and 132c penetrating the base portion 132 in the axial direction and through holes 132b penetrating the inserted portion 131 in the radial direction. Further, the second engaging portion 133 of the illustrated example has a hook-like structure having an engaging convex portion 133a at the tip of the elastic piece 133b protruding from the tip side toward the outside in the radial direction. A plurality of elastic pieces 133b having the engaging convex portion 133a are arranged in the circumferential direction. In addition to the through holes 132a, 132b, 132c, it is possible to allow fluid to flow between the second engaging portions 133 of the hook-like structure. Thereby, in the open position, the supply from the inside to the outside of the receiving portion 130 can be promoted.

The first engaging portion 123 has a mushroom shape having an engaging head 123a at the tip of the strut portion 123b. The maximum diameter of the engaging head 123a is made larger than the outer diameter of the strut portion 123b. A plurality of engaging protrusions 133a surround the engagement head 123a and elastically deform toward the outer peripheral surface of the support column 123b, so that the valve body 120 remains in the closed position and the first engaging portion 123 and the first engaging portion 123a 2 It is possible to engage with the engaging portion 133. Further, when the insertion portion 111 is moved away from the base portion 132 of the receiving portion 130, the plurality of engaging convex portions 133a are elastically deformed radially outward from the periphery of the engaging head 123a, so that the first engaging portion 111 is engaged. The engagement between the joint portion 123 and the second engaging portion 133 is released.

That is, in a state where the first engaging portion 123 and the second engaging portion 133 are engaged at the closed position, the insertion portion 111 is moved to the tip side in the axial direction, whereby the first engaging portion 123 and the tip are engaged. The pouring flow path 115 is opened between the opening 112a and the opening 112a. Further, in a state where the first engaging portion 123 and the second engaging portion 133 are engaged in the open position, the insertion portion 111 is moved to the base end side in the axial direction to form the first engaging portion 123 with the first engaging portion 123. The pouring flow path 115 is closed between the tip opening 112a and the first engaging portion 123 and the second engaging portion 133 are disengaged.

In the second embodiment, the guide portion 114 projecting from the proximal end portion 113 of the insertion portion 111 to the proximal end side is arranged. A plurality of guide portions 114 are formed so as to be spaced apart from each other in the circumferential direction of the insertion portion 111. In the illustrated example, two guide portions 114 are arranged at 180 ° intervals in the circumferential direction. Further, a through hole 125a penetrating in the axial direction is formed in the base end portion 125 of the valve body 120. The fluid in the first container can reach the pouring flow path 115 in the insertion portion 111 through the gap between the guide portions 114 and the through hole 125a.

The guide portion 114 is formed with a closing side projection 114a that contacts the base end portion 125 of the valve body 120 at the closing position and an opening side projection 114b that contacts the base end portion 125 of the valve body 120 at the opening position. .. The closing side projection 114a is formed radially inward in the intermediate portion of the guide portion 114. The open side protrusion 114b is formed radially inward at an end portion of the guide portion 114 opposite to the base end portion 113 side.

The amount of protrusion of the closing side protrusion 114a from the guide portion 114 is so small that the valve body 120 does not interfere with the displacement when the valve body 120 is displaced between the closing position and the opening position. Therefore, when no external force acts on the insertion portion 111 and the valve body 120, the valve body 120 can be held in the closed position. Further, when the insertion portion 111 is further displaced in the axial direction while the first engaging portion 123 and the second engaging portion 133 are engaged, the base end portion 125 is displaced beyond the closing side projection 114a. It is designed not to prevent you from doing so.

The open side protrusion 114b has a large protrusion amount enough to prevent displacement of the valve body 120 in the direction away from the tip opening 112a when the base end portion 125 is in contact with the open side protrusion 114b. As a result, when the first engaging portion 123 and the second engaging portion 133 are engaged and the insertion portion 111 is further displaced in the direction of approaching the receiving portion 130, the displacement of the valve body 120 becomes excessive. It can be regulated so that it does not become.

As shown in FIG. 6, when the base end portion 125 is in contact with the open side protrusion 114b, the tip end portion 112 of the insertion portion 111 may be in contact with the base portion 132 of the receiving portion 130. In this case, the insertion portion 111 is prevented from entering the second container beyond the base portion 132. If the first engaging portion 123 and the second engaging portion 133 are engaged, the valve body 120 will not be separated from the dispensing member 110. When the valve body 120 is in the open position, even if the engagement between the first engaging portion 123 and the second engaging portion 133 is released due to some impact or the like, the valve body 120 exceeds the open side protrusion 114b. It is blocked from entering the first container.

According to the above-described embodiment, the first engaging portions 23 and 123 are exposed to the tip openings 12a and 112a of the inserting portions 11 and 111 at the closing positions of the valve bodies 20 and 120. The first engaging portions 23, 123 engage with the second engaging portions 33, 133 arranged in the inserted portions 31, 131 having the insertion holes 31a, 131a, and this engagement is maintained even in the open position. To. Therefore, the structure is such that the fluid to be injected does not easily accumulate inside the injection members 10 and 110.

In the above-described embodiment, the injection members 10, 110 and the valve bodies 20, 120 are composed of separate members. Therefore, the injection members 10, 110 and the valve bodies 20, 120 may be made of different materials. For example, the pouring members 10 and 110 may be made of a flexible material, and the valve bodies 20 and 120 may be made of a hard material. As a result, the pouring members 10 and 110 can be deformed so as to follow the shapes of the valve bodies 20 and 120, so that the airtightness of the pouring flow paths 15 and 115 can be easily improved. As the flexible material and the hard material, resins having different elastic moduli such as Young's modulus may be appropriately selected.

The injection members 10, 110, the valve bodies 20, 120, and the receiving portions 30, 130 can each be formed of an integral molded product. The molding material is not particularly limited, and examples thereof include resin, rubber, elastomer, and metal. The injection members 10, 110 may be composed of two or more members. Further, the valve bodies 20 and 120 may be composed of two or more members. Further, the receiving portions 30 and 130 may be composed of two or more members.

The packaging container having the dispensing member connecting structure of the above-described embodiment includes a first container having the dispensing members 10, 110 and the valve bodies 20, 120, and a second container having receiving portions 30, 130. There is. For the handling of the first container and the second container, the user may directly operate the first container with respect to the second container. The first container and the second container may be incorporated into the mechanical device, and the first container or the second container may be displaced when the user operates the mechanical device or when the mechanical device recognizes the necessity.

The first container and the second container may be a large container or a small container. For example, when the container is large or the shape in the plane perpendicular to the axial direction is non-circular, when the valve bodies 20 and 120 are displaced in the axial direction, the pouring members 10 and 110 are rotated. It is preferable that the receiving portions 30 and 130 can be connected and disconnected without being rotated in the direction. The dispensing operation can be performed by simply pushing the dispensing members 10 and 110 toward the receiving portions 30 and 130 in the axial direction, and by simply pulling in the receiving portions 30 and 130 in the axial direction, the dispensing members 10 and 110. Can be removed. Therefore, even when either the user or the mechanical device operates the packaging container, the operation becomes easy.

The type of container is not particularly limited, and examples thereof include a pouch container, a bottle container, a tube container, and a box container. The molding material of the first container and the second container is not particularly limited, and examples thereof include resin, metal, paper, and laminate. The injection members 10, 110 may be joined to the first container, or the injection members 10, 110 and the first container may be integrally molded. Further, the receiving portions 30 and 130 may be joined to the second container, and the receiving portions 30 and 130 and the second container can be integrally molded. The first container and the second container may have different points in shape, dimensions, type, material, and the like.
