Description

The present invention relates to a dispensing container.

2. Description of the Related Art As a pouring container for pouring out a content, for example, as shown in Patent Document 1 below, a pouring container having two pouring holes (nozzle holes) is known.
In this pouring container, a pouring hole is formed by a part of the cap body attached to the mouth of the container body and a part of the auxiliary cap detachably combined with the cap body. The two pouring holes are provided so as to face each other in the radial direction across the container axis.

Japanese Patent Application Publication No. 9-99965

However, in conventional pouring containers, when pouring the contents, it is necessary to grasp the container body with fingertips while checking the position of the pouring hole, and tilt the container body so that the pouring hole faces the direction of pouring. Therefore, the operability is poor and there is room for improvement.
In particular, when pouring the contents several times in succession, it is necessary to check the orientation of the pouring hole each time, which is cumbersome and inconvenient to use.

The present invention was made in consideration of these circumstances, and its purpose is to provide a pouring container that allows the contents to be poured out without having to worry about the orientation of the pouring hole.

(1) The pouring container according to the present invention comprises a container body including an inner container in which the contents are stored and an outer container in which the inner container is fitted, and a pouring member attached to the mouth of the inner container and having a pouring nozzle with an opening through which the pouring hole is opened, the inner container is accommodated within the outer container so as to be rotatable around the central axis of the outer container, the pouring hole is positioned above the outer container, a support member is provided between the bottom of the inner container and the bottom of the outer container to rotatably support the inner container relative to the outer container, and the body of the inner container has a weight portion that is heavier than other portions of the body in a cross-sectional view perpendicular to the central axis.

According to the pouring container of the present invention, an inner container having a body whose center of gravity is biased to one side due to a weight part is accommodated in an outer container so as to be rotatable around a central axis. Therefore, when pouring out the contents, no matter from which direction the outer container is held with fingertips or the like, when the container body is tilted, the inner container can be rotated naturally within the outer container by utilizing gravity so that the weight part faces downward. At this time, a support member is provided between the bottom of the inner container and the bottom of the outer container, so that the inner container can be rotated smoothly.
Therefore, when the container body is tilted, the attitude of the inner container can be kept constant so that the weight part always faces downward, regardless of the orientation (attitude) of the outer container when the outer container is gripped, and the orientation of the pouring hole in the pouring member attached to the inner container can also be kept constant. This allows the contents to be poured out without having to worry about the orientation of the pouring hole. This makes it possible to provide a pouring container that is easy to use and has excellent operability.

(2) The body of the inner container, in the cross-sectional view, comprises a first curved body portion extending along the circumferential direction of the body portion, and a second curved body portion extending along the circumferential direction of the body portion and connected via peripheral ends of the first curved body portion located on both sides in the circumferential direction, the second curved body portion being formed with a constant thickness along the circumferential direction and being formed so as to be biased toward the central axis more than the first curved body portion, the first curved body portion being formed thicker than the second curved body portion along the circumferential direction, and the weight portion When a virtual line passing through the peripheral end and the central axis in the cross-sectional view is defined as a first virtual line, and a virtual line perpendicular to the first virtual line and passing through the central axis is defined as a second virtual line, the first curved body portion and the second curved body portion may each be formed such that the distance from the central axis to the inner peripheral surface of the first curved body portion and the inner peripheral surface of the second curved body portion are shortest on the second virtual line and gradually increase from the second virtual line toward the peripheral end.

In this case, the body of the inner container is formed by the first curved body and the second curved body connected via the peripheral end of the first curved body. In particular, the first curved body is made thicker than the second curved body, which is formed with a constant thickness (wall thickness), so that the first curved body functions as a weight part. Therefore, there is no need to prepare a separate member as a weight part, and a body having a weight part can be formed easily and at low cost by utilizing the difference in wall thickness.

Furthermore, the second curved body portion can be formed into an arc shape biased toward the central axis in cross section so that the radius of curvature of the second curved body portion is smaller than the radius of curvature of the first curved body portion which is formed to be thick. This allows the shape of the body portion of the inner container to be made uneven with the center of gravity further biased toward the first curved body portion, and makes it possible to actively encourage rotation of the inner container by utilizing gravity when the container body is tilted.
Furthermore, the first curved body portion and the second curved body portion are formed so that the distance from the central axis to the inner peripheral surface of the first curved body portion and the inner peripheral surface of the second curved body portion is shortest on the second virtual straight line and gradually increases from the second virtual straight line toward the peripheral end. This allows the internal space of the body portion of the inner container to be formed into an uneven elliptical shape that bulges greatly toward the first curved body portion, with the first virtual straight line as the major axis and the second virtual straight line as the minor axis, when viewed in cross section. Therefore, when the container body is tilted, the contents can be concentrated more toward the first curved body portion, and the weight of the contents themselves can also be utilized to more actively promote rotation of the inner container.

(3) The pouring hole may be formed so as to be inclined with respect to the central axis in a vertical cross-sectional view of the container body, and the circumferential position of the uppermost part of the pouring hole may coincide with the circumferential position of the weight portion in a circumferential direction around the central axis.

In this case, the circumferential position of the top of the pouring hole coincides with the circumferential position of the weight portion, so when the container body is tilted and the inner container is rotated so that the weight portion faces downward, the top of the pouring hole can also face downward in correspondence with the inner container. Therefore, the top can be used as a so-called pouring lip, and the contents can be poured out smoothly and with good liquid drainage, for example.

(4) The dispensing nozzle is provided with a pendulum member that can swing around a swing axis, and the pendulum member includes a pendulum body connected to the dispensing nozzle so as to be able to swing around the swing axis, a weight portion connected to one end of the pendulum body, positioned below the swing axis and positioned on the uppermost side of the dispensing nozzle, and a nozzle lid portion connected to the other end of the pendulum body, positioned above the swing axis and positioned on the opposite side of the weight portion to the dispensing nozzle, and the nozzle lid portion may close the dispensing hole and open the dispensing hole as the pendulum member swings around the swing axis.

In this case, when the pouring container is not in use or is in storage, the nozzle lid closes the pouring hole, preventing the intrusion of foreign matter. When the container body is tilted and the inner container is rotated so that the weight part faces downwards to pour out the contents, the weight part can be moved by gravity. This allows the entire pendulum member to swing around the swing axis. In particular, the nozzle lid can be displaced by the pendulum body swinging around the swing axis due to the movement of the weight part, so that the pouring hole can be shifted from a blocked state to an open state.
Therefore, the pouring hole can be opened naturally as the inner container is rotated. Therefore, there is no need to operate the nozzle lid separately, and the pouring hole can be opened in a single process of grasping the outer container and tilting the container body, allowing the contents to be poured out.

The dispensing container of the present invention allows the contents to be dispensed without having to worry about the orientation of the dispensing hole.

FIG. FIG. 11 is a vertical cross-sectional view showing a modified example of the dispensing container. A cross-sectional view of the dispensing container taken along line C-C' shown in Figure 7.

Hereinafter, an embodiment of a pouring container according to the present invention will be described with reference to the drawings.
As shown in FIG. 1, the dispensing container 1 of this embodiment comprises a container body 2 having an inner container 3 in which a content M is contained and an outer container 4 in which the inner container 3 is fitted, and a dispensing member 5 attached to the mouth portion 20 of the inner container 3.
Unless otherwise specified, each component part of the pouring container 1 is a molded product made of synthetic resin. The contents M are not particularly limited, but may be, for example, a liquid content such as a liquid seasoning, a powder content, or a granular content.

In this embodiment, the container axis of the outer container 4 is referred to as the central axis O1, the side of the mouth 10 of the outer container 4 along the central axis O1 is referred to as the upper side, and the opposite side is referred to as the lower side. In addition, in a plan view seen from the direction of the central axis O1, the direction intersecting the central axis O1 is referred to as the radial direction, and the direction going around the central axis O1 is referred to as the circumferential direction.

(Outer container)
The outer container 4 is formed in a bottomed cylindrical shape with a mouth 10, a body 11, and a bottom 12 arranged in sequence from the top. The material of the outer container 4 is not particularly limited, but is, for example, PET (polyethylene terephthalate) resin. Furthermore, the outer container 4 has a certain rigidity, and is configured such that when the body 11 is gripped with, for example, fingertips, the body 11 is unlikely to deform radially inward.

A first male screw portion 13 is formed on the outer peripheral surface of the mouth portion 10 of the outer container 4. The body portion 11 of the outer container 4 is formed in a cylindrical shape extending linearly in the vertical direction. A support protrusion 14 that protrudes upward is formed on the bottom portion 12 of the outer container 4. The support protrusion 14 is disposed at the center of the bottom portion 12 and is formed, for example, in a conical shape centered on the central axis O1. The top portion 14a of the support protrusion 14 is formed in a rounded spherical shape.

(Inner container)
The inner container 3 is formed into a bottomed cylindrical shape with a mouth 20, a body 21, and a bottom 22 arranged in sequence from the top, and is housed inside the outer container 4. The material of the inner container 3 is not particularly limited, but is, for example, PET resin like the outer container 4. Furthermore, like the outer container 4, the inner container 3 has a certain degree of rigidity.

The inner container 3 is housed in the outer container 4 so as to be rotatable around the central axis O1. This allows the inner container 3 to rotate relative to the outer container 4 around the central axis O1. A support member 6 is provided between the bottom 22 of the inner container 3 and the bottom 12 of the outer container 4, supporting the inner container 3 so as to be rotatable relative to the outer container 4.

The inner container 3 is not disposed coaxially with the central axis O1, but is disposed in the outer container 4 in a state offset to one side in the radial direction with respect to the central axis O1. As a result, as shown in Figures 1 and 2, the space between the body 11 of the outer container 4 and the body 21 of the inner container 3 is not uniform in the circumferential direction but is non-uniform.
1, the inner container 3 is accommodated inside the outer container 4 such that the mouth 20 is positioned inside the mouth 10 of the outer container 4. A second male screw portion 23 is formed on the outer peripheral surface of the mouth 20.

The bottom 22 of the inner container 3 is formed with a bulge 24 that protrudes upward. The bulge 24 is formed in a cone shape with its apex 24a located on the central axis O1. The lower surface of the bottom 22 of the inner container 3 is formed with a recess 25 that is recessed upward by the bulge 24. The support protrusion 14 formed on the outer container 4 enters the recess 25 from below, and the apex 14a of the support protrusion 14 contacts (point contacts) the apex 24a of the bulge 24 from below.
As a result, the inner container 3 is supported rotatably about the central axis O1 by the support protrusions 14. Therefore, the support protrusions 14 formed on the outer container 4 and the bulging portions 24 formed on the inner container 3 function as the support members 6 described above.

As shown in Figures 1 and 2, the body 21 of the inner container 3 is provided with a weight section 7 that is heavier than other parts of the body 21 in a cross-sectional view perpendicular to the central axis O1. In this embodiment, the thickness (wall thickness) of the body 21 of the inner container 3 is made non-uniform in the circumferential direction, and the difference in wall thickness is used to function as the weight section 7.

The body 21 of the inner container 3, when viewed in cross section, comprises a first curved body portion 30 extending circumferentially of the body portion 21, and a second curved body portion 32 extending circumferentially of the body portion 21 and connected via peripheral end portions 31 located on both circumferential sides of the first curved body portion 30.
In a cross-sectional view, the first curved body portion 30 and the second curved body portion 32 are arranged to face each other in the radial direction with the central axis O1 in between. Furthermore, in a cross-sectional view, the outer peripheral surface of the first curved body portion 30 is formed in a semicircular shape centered on the central axis O1, and is arranged with a certain gap between it and the inner peripheral surface of the body portion 21 of the inner container 3. As a result, the peripheral ends 31 of the first curved body portion 30 are arranged to face each other in the radial direction with the central axis O1 in between.

In this embodiment, as shown in FIG. 2, in the cross-sectional view, a virtual line passing through the peripheral end portion 31 of the first curved body portion 30 and the central axis O1 is defined as a first virtual straight line L1, and a virtual line perpendicular to the first virtual straight line L1 and passing through the central axis O1 is defined as a second virtual straight line L2.

In cross section, the second curved body portion 32 is formed with a constant thickness along the circumferential direction, and is formed in an arc shape biased toward the central axis O1 side more than the first curved body portion 30. As a result, the outer shape of the body portion 21 of the inner container 3 is not cylindrical but is non-uniform.
In a cross-sectional view, the first curved body portion 30 is formed to be thicker along the circumferential direction than the second curved body portion 32. As a result, the first curved body portion 30 functions as the weight portion 7.

The first curved body portion 30 and the second curved body portion 32 will now be described in detail.
In the cross section, the outer peripheral surface of the first curved body portion 30 is formed in a semicircular shape centered on the central axis O1 as described above. In contrast, the inner peripheral surface of the first curved body portion 30 is not formed in a semicircular shape centered on the central axis O1, but is formed in an arc shape whose distance from the central axis O1 changes along the circumferential direction.
Specifically, the first curved body portion 30 is formed so that the distance H from the central axis O1 to the inner surface of the first curved body portion 30 is shortest on the second imaginary straight line L2 (H1 in Figure 2), and gradually becomes longer from the second imaginary straight line L2 toward the peripheral end portion 31.
As a result, the thickness of the first curved body portion 30 is made thicker than the thickness of the second curved body portion 32 and is formed so as to vary along the circumferential direction. In particular, the thickness of the first curved body portion 30 is formed so as to be thickest on the second virtual straight line L2.

The outer and inner surfaces of the second curved body portion 32 are not formed in a semicircular shape centered on the central axis O1, but are both formed in an arc shape whose distance from the central axis O1 changes along the circumferential direction.
Specifically, the second curved body portion 32 is formed so that the distance W from the central axis O1 to the inner surface of the second curved body portion 32 is shortest on the second imaginary straight line L2 (W1 in Figure 2), and gradually becomes longer from the second imaginary straight line L2 toward the peripheral end portion 31.
The distance W1 in the second curved body portion 32 is shorter than the distance H1 in the first curved body portion 30.

The body 21 of the inner container 3 is continuously formed over its entire length in the vertical direction by the above-mentioned first curved body portion 30 and second curved body portion 32. In particular, the internal space of the body 21 of the inner container 3 is formed into a non-uniform elliptical shape that bulges greatly toward the first curved body portion 30 side, with the first imaginary straight line L1 as the major axis and the second imaginary straight line L2 as the minor axis, in a cross-sectional view.
Therefore, the contents M contained in the inner container 3 are contained in a larger amount on the first curved body portion 30 side than on the second curved body portion 32 side.

(Pour-out member)
As shown in FIG. 1 , the pouring member 5 includes a topped cylindrical attachment tube 40 that is attached to the mouth 20 of the inner container 3 , and a pouring nozzle 45 that extends upward from a top wall portion 42 of the attachment tube 40 .

The mounting tube 40 has a peripheral wall portion 41 that surrounds the mouth 20 of the inner container 3 from the outside in the radial direction, and a top wall portion 42 that closes the upper end opening of the peripheral wall portion 41. A second female thread portion 43 that is screwed into the second male thread portion 23 formed on the mouth 20 of the inner container 3 is formed on the inner circumferential surface of the peripheral wall portion 41. As a result, the entire pouring member 5 is mounted to the mouth 20 of the inner container 3 by screw connection.
However, the method of mounting the discharging member 5 is not limited to screw connection, and it may be mounted by, for example, undercut fitting.

The top wall 42 contacts the upper opening edge of the mouth 20 of the inner container 3 from above via an annular packing. This allows the mounting tube 40 to be mounted on the mouth 20 of the inner container 3 while ensuring a certain level of sealing.

The pouring nozzle 45 is disposed coaxially with the central axis O1, and is formed in a cylindrical shape extending linearly upward from the top wall portion 42. The inside of the pouring nozzle 45 communicates with the inside of the inner container 3 through a communication hole 42a formed in the top wall portion 42. A pouring hole 46 for pouring out the content M is opened at the upper end of the pouring nozzle 45.
In this embodiment, the pouring hole 46 is formed so as to be inclined with respect to the central axis O1 in a vertical cross-sectional view of the container body 2. In this case, the circumferential position of the uppermost part 46a of the pouring hole 46 coincides with the circumferential position of the weight part 7 of the inner container 3, i.e., the first curved body part 30. More specifically, the circumferential position of the uppermost part 46a of the pouring hole 46 coincides with the circumferential position of the thickest part of the first curved body part 30.

(Support cap)
A support cap 50 is attached to the mouth 10 of the outer container 4 to restrict the upward movement of the inner container 3 relative to the outer container 4 .
The support cap 50 comprises a cap peripheral wall 51 that surrounds the mouth 10 of the outer container 4 from the radial outside, and a ring-shaped cap top wall 52 that protrudes radially inward from the upper end of the cap peripheral wall 51 and covers the upper end opening of the outer container 4.

A first female thread portion 53 is formed on the inner peripheral surface of the cap peripheral wall 51, which is screwed into the first male thread portion 13 formed on the mouth portion 10 of the outer container 4. As a result, the entire support cap 50 is attached to the mouth portion 10 of the outer container 4 by screw connection. However, the method of attaching the support cap 50 is not limited to screw connection, and it may be attached by, for example, undercut fitting.
The inner peripheral edge of the cap top wall 52 covers a part of the top wall 42 of the pouring member 5 from above. As a result, the cap top wall 52 prevents the entire inner container 3 from moving upward (falling out) from within the outer container 4, and the inner container 3 is appropriately positioned in the vertical direction within the outer container 4.

(Pendulum member)
The pouring nozzle 45 of the pouring member 5 is provided with a pendulum member 60 .
The pendulum member 60 is attached to the dispensing nozzle 45 via a swing shaft 61 that protrudes radially outward from the outer circumferential surface of the dispensing nozzle 45. In this case, the pendulum member 60 is capable of swinging about a swing axis O2 that passes through the center of the swing shaft 61.
The swing shaft 61 is formed so as to be parallel to the second imaginary straight line L2, so that the pendulum member 60 can swing up and down along the first imaginary straight line L1.

The pendulum member 60 comprises a pendulum body 62 connected to the dispensing nozzle 45 via an oscillating shaft 61, a weight portion 63 connected to the lower end (one end) of the pendulum body 62, and a nozzle lid portion 64 connected to the upper end (other end) of the pendulum member 60.
The pendulum body 62 is formed in a plate shape arranged in a state inclined with respect to the central axis O1 in a vertical cross-sectional view of the container body 2. The lower end of the pendulum body 62 is arranged below the swing axis O2 and is arranged on the uppermost part 46a side with respect to the dispensing nozzle 45. In contrast, the upper end of the pendulum body 62 is arranged above the swing axis O2 and is arranged on the opposite side of the lower end of the pendulum body 62 with respect to the dispensing nozzle 45.

The weight portion 63 is formed to extend parallel to the oscillation axis O2, and is integrally connected to the lower end portion of the pendulum body 62. As a result, the weight portion 63 is in contact with the pouring nozzle 45 so as to be able to be separated therefrom.
The nozzle lid 64 is formed in a plate shape that covers the pouring hole 46 from above, and is integrally connected to the upper end of the pendulum body 62. In this way, the nozzle lid 64 releasably closes the pouring hole 46. In particular, the nozzle lid 64 is configured to switch between a state in which the pouring hole 46 is closed and a state in which the pouring hole 46 is open as the pendulum member 60 swings about the swing axis O2.

(Function of the pouring container)
Next, a case where the content M is poured out using the pouring container 1 configured as described above will be described.
In the pouring container 1 of this embodiment, the inner container 3 having the body 21 whose center of gravity is biased to one side by the weight part 7 (the thick first curved body part 30) is rotatably accommodated in the outer container 4. Therefore, when pouring out the contents M, no matter from which direction the outer container 4 is held with fingertips or the like, when the container body 2 is tilted as shown in Fig. 3, the inner container 3 can be naturally rotated in the outer container 4 by utilizing gravity so that the weight part 7 faces downward as shown by the arrow in Fig. 4.

At this time, as shown in FIG. 3, a support member 6 (support protrusion 14, bulge 24) is provided between the inner container 3 and the outer container 4, and a support cap 50 is also provided, so that the inner container 3 can be rotated smoothly while preventing the inner container 3 from falling out of the outer container 4.

Therefore, when the container body 2 is tilted, the posture of the inner container 3 can be kept constant so that the weight section 7 always faces downward, as shown in FIG. 5, regardless of the orientation (posture) of the outer container 4 when the outer container 4 is grasped. Furthermore, the orientation of the pouring hole 46 in the pouring member 5 attached to the inner container 3 can also be kept constant. This allows the contents M to be poured out without having to worry about the orientation of the pouring hole 46, as shown in FIG. 6. This makes it possible to provide a pouring container 1 that is easy to use and has excellent operability.

The pouring container 1 of this embodiment further includes a pendulum member 60 .
Therefore, as shown in FIG. 1, when the pouring container 1 is not in use or is in storage, the nozzle lid portion 64 closes the pouring hole 46, thereby preventing the intrusion of foreign matter.
When pouring out the content M, if the container body 2 is tilted and the inner container 3 is rotated so that the weight section 7 faces downward, the weight section 63 can be moved by gravity as shown by the arrow in Fig. 5. This allows the entire pendulum member 60 to swing around the swing axis O2. In particular, the movement of the weight section 63 causes the pendulum body 62 to swing around the swing axis O2, displacing the nozzle lid section 64, so that the pouring hole 46 can be shifted from a closed state to an open state.

As a result, the pouring hole 46 can be opened naturally as the inner container 3 rotates. This eliminates the need to operate the nozzle lid 64 separately, and the pouring hole 46 can be opened as shown in FIG. 6 in the course of grasping the outer container 4 and tilting the container body 2, allowing the contents M to be poured out.

Furthermore, in this embodiment, as shown in Figs. 1 and 2, the body 21 of the inner container 3 is formed by the first curved body 30 and the second curved body 32. In particular, the first curved body 30 is made thick so that it functions as the weight section 7. Therefore, there is no need to prepare a separate member as the weight section 7, and the body 21 having the weight section 7 can be formed easily and at low cost by utilizing the difference in thickness.

Furthermore, since the second curved body 32 is formed in an arc shape biased toward the central axis O1, the body 21 of the inner container 3 can be formed into an uneven shape with the center of gravity further biased toward the first curved body 30. Therefore, when the container body 2 is tilted, the rotation of the inner container 3 can be actively promoted by utilizing gravity. In addition, the internal space of the body 21 of the inner container 3 is formed in an uneven elliptical shape that bulges greatly toward the first curved body 30 side in a cross-sectional view, with the first virtual straight line L1 as the major axis and the second virtual straight line L2 as the minor axis. As a result, when the container body 2 is tilted, a large amount of the contents M can be gathered on the first curved body 30 side, and the weight of the contents M itself can also be utilized to actively promote the rotation of the inner container 3.

Furthermore, since the circumferential position of the top 46a of the pouring hole 46 coincides with the circumferential position of the weight section 7 (the thickest part of the first curved body section 30), when the container body 2 is tilted and the inner container 3 is rotated so that the weight section 7 faces downward, the top 46a of the pouring hole 46 can also face downward in correspondence with the inner container 3, as shown in Figures 5 and 6. Therefore, the top 46a can be used as a so-called pouring lip, and the contents M can be poured out smoothly and, for example, with good liquid drainage.

Although the embodiments of the present invention have been described above, these embodiments are presented as examples and are not intended to limit the scope of the invention. The embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the gist of the invention. Examples of the embodiments and their variations include those that can be easily imagined by a person skilled in the art, those that are substantially the same, and those that are within the scope of equivalents.

For example, in the above embodiment, the second curved body portion 32 may be formed in a semicircular shape centered on the central axis O1 in a cross-sectional view. Even in this case, the thick first curved body portion 30 can function as the weight portion 7, so that the same effect can be achieved.
However, as in the above embodiment, forming the second curved body portion 32 in an arc shape biased toward the central axis O1 is more preferable because it can more actively encourage rotation of the inner container 3.

Furthermore, in the above embodiment, the case where the thick first curved body portion 30 functions as the weight portion 7 has been described as an example, but this is not limited to this case. For example, the thickness (wall thickness) of the body portion 21 of the inner container 3 may be made uniform in the circumferential direction, and then a weight member (e.g., a metal member) having a greater specific gravity than the material of the inner container 3 may be integrally molded into a part of the body portion 21, so that the weight member functions as the weight portion 7. Even in this case, the same effect can be achieved.

Furthermore, when a weight member is used, it may be combined with, for example, a thick first curved body portion 30 .
For example, as shown in Figs. 7 and 8, a pouring container 70 may be formed in which a weight member 71 is integrally formed with the thickest portion of the first curved body portion 30.
According to the pouring container 70 in this case, the weight portion 7 can be made even heavier, so that the inner container 3 can be rotated more actively, and the usability is further improved.
In the illustrated example, the second curved body portion 32 is formed in a semicircular shape centered on the central axis O1 in a cross-sectional view. However, the second curved body portion 32 may be formed in the same manner as the pouring container 1 of the above embodiment. Furthermore, in the illustrated example, the pouring container 70 is shown as an example that does not include a pendulum member 60. In this way, the pendulum member 60 is not essential and may not be included.
