DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container lid applied to the mouth and neck of a container containing a liquid, and more particularly, to a container lid provided with an outflow tube for allowing the liquid in the container to flow out.

[0002]

2. Description of the Related Art Japanese Unexamined Utility Model Publication No. 60-96254 and Japanese Unexamined Utility Model Publication No. 60-96255 disclose a container lid applied to the mouth and neck of a container containing a liquid such as a beverage. And a container lid provided with an outflow cylinder attached to the lid body. The lid body has a circular main wall and a cylindrical skirt wall hanging from the periphery of the main wall, and the skirt wall is fitted on the outer peripheral surface of the mouth and neck of the container,
The main wall covers the top of the mouth and neck. Outflow holes are formed in the main wall. The outflow tube is mounted on the upper surface of the main wall of the lid main body so as to be pivotable between an upright outflow position and an upright closed position. The outflow cylinder is provided with a through-outflow path, and when the outflow cylinder is set up at the outflow position, the through-outflow path of the outflow cylinder is made to communicate with the inside of the container through an outflow hole in the main wall of the lid main body. For example, the contents of the container can be drunk by holding the outlet tube in the mouth and sucking. When the outflow tube is turned down to the closed position, the through-flow channel is disconnected from the outflow hole.

[0003]

However, the conventional container lid of the above-described embodiment has the following problems to be solved. First, the outlet tube is always exposed, which is not hygienic when the outlet tube is held in the mouth. Secondly, in the form disclosed in Japanese Utility Model Laid-Open No. 60-96254, it is necessary to directly put a finger on the outflow cylinder in order to turn the outflow cylinder, which is also preferable from the viewpoint of hygiene. Absent. On the other hand, in the embodiment disclosed in Japanese Utility Model Application Laid-Open No. 60-96255, the outflow cylinder can be turned by operating the turning means provided on the main wall of the lid main body. The production is not always easy due to the configuration relating to the connection between the turning means and the outflow cylinder together with the configuration.

[0004] The first problem can be solved by adding an outer lid which covers the main wall of the lid main body and the outflow cylinder which is positioned at the closed position. However, when the outer lid is simply added, when the contents of the container are allowed to flow out, the outer lid is moved to the open position with respect to the lid main body or separated from the lid main body, and the outflow cylinder is further moved from the closed position. Need to stand up at the spill location,
After the outflow of the contents of the container is completed, it is necessary to lower the outflow cylinder from the outflow position to the closed position, and further move the outer lid to the closed position with respect to the lid body or fit the outer lid on the lid body. In addition, the operation of the container lid becomes considerably complicated.

[0005] In order to solve the above-mentioned problems encountered with the conventional container lid, the present inventors first disclosed in Japanese Patent Application No.
In the specification and drawings of JP-A-00-57286, the outflow cylinder is pivotally mounted on the upper surface of the main wall of the lid main body, and the outer lid is pivotally mounted on the lid main body. When the dimensions and the like are appropriately set and the outer lid is swung from the closed position to the open position, the outer lid interferes with the outflow cylinder in the closed position and raises the outflow cylinder from the closed position to the outflow position, Then, it is pivoted to the open position apart from the outflow tube due to the elastic deformation of the outer lid and / or the outflow tube,
When the outer lid is pivoted from the open position to the closed position, the outer lid interferes with the outflow tube at the outflow position, causes the outflow tube to fall down from the outflow position to the closed position, and is pivoted to the closed position. A container lid configured as described above was proposed. An outflow position regulating piece and a closing position regulating piece are arranged on the main wall of the lid body, and when the outflow cylinder is raised to the outflow position, the outflow cylinder is brought into contact with the outflow position regulating piece to cause the outflow cylinder to come into contact with the outflow cylinder. Is prevented from pivoting beyond the outflow position, and when the outflow cylinder is laid down to the closed position, the outflow cylinder is brought into contact with the closing position restricting piece, and when the outflow cylinder is swirled or laid down over the closed position. Is blocked. In such a container lid, even if an outer lid capable of covering the main wall of the lid main body and the outflow cylinder in the closed position is added, if the outer lid is simply opened and closed, the outflow is correspondingly performed. The tube is turned, ie, erected and laid down, as required.

However, it has been found that the container lid proposed by the present inventors has the following problems to be solved. That is, there is no particular problem when the outflow cylinder is swirled as required in accordance with the swiveling movement of the outer lid, but when the outer lid is located at the open position, the outflow cylinder is accidentally singly. When the outer lid is turned down to the closed position, the outer lid is pivoted to the closed position, as will be described in more detail later, and more specifically, when the outer lid interferes with the outflow cylinder in the closed position, the outer lid and It is rather difficult, if not impossible, to make the outflow tube enter the outer lid by elastically deforming the outflow tube.

Further, when the liquid contained in the container is, for example, a cleaning liquid, it is desired to measure and use the liquid. However, in the above-described embodiment, consideration has been given to the measurement in the conventional container lid. Absent.

The present invention has been made in view of the above-mentioned facts, and a main technical problem thereof is a form including an outflow cylinder and an outer lid in addition to a lid main body. In addition to the fact that the outflow tube is raised and laid down as required, it is also easy enough if the outflow tube is independently laid down in the closed position when the outer lid is in the open position. It is another object of the present invention to provide a new and improved container lid capable of pivoting the outer lid from the open position to the closed position to allow the outflow tube to enter the outer lid.

Another technical problem of the present invention is that the outflow cylinder and the outer lid are provided in addition to the lid main body. When the outer lid is opened and closed, the outflow cylinder rises and falls down as required. In addition, it is an object of the present invention to provide a new and improved container lid capable of conveniently measuring and discharging the liquid contained in the container using the outer lid as a measuring cup.

[0010] In one aspect of the present invention, the present inventors have made the following improvement to the previously proposed container lid, that is, tilting when a pressing force of a predetermined value or more acts on the closing position regulating piece. After the outflow cylinder is laid down and abutted against the closing position restricting piece, if a pressing force equal to or more than a predetermined value is applied to the closing position restricting piece via the outflow cylinder, the closing position restricting piece will The above-mentioned main technical problem is caused by a configuration in which the closing position regulating piece is elastically restored when the outflow cylinder is further tilted down and the pressing force via the outflow cylinder is released, and the closing position regulating piece is elastically restored. Can be achieved.

That is, according to one aspect of the present invention, a container lid for achieving the above-mentioned main technical problem comprises a lid body attached to the mouth and neck of the container, an outflow cylinder having a through-flow channel, and an outer lid. The lid body has a main wall that covers the top surface of the mouth and neck of the container, and an outflow hole is provided in the main wall, and the outflow cylinder is pivotally mounted on the upper surface of the main wall of the lid body. At the outflow position which is mounted and extends upward from the outflow hole of the main wall, the through outflow channel is communicated with the container through the outflow hole, and when it is turned down to the closed position, the through outflow channel is opened. The outer lid is not in communication with the outlet hole, and the outer lid is mounted on the lid body so as to be pivotable between a closed position and an open position. In the closed position, the main wall of the lid main body and the outlet are disposed. Cover the cylinder and, in the open position, expose the main wall of the lid body and the outflow cylinder; When is rotated from the closed position to the open position, the outer lid interferes with the outflow tube in the closed position to cause the outflow tube to rise from the closed position to the outflow position, and then the outflow When the outer lid is pivoted to the open position away from the cylinder and the outer lid is pivoted from the open position to the closed position, the outer lid interferes with the outflow cylinder at the outflow position and causes the outflow. A closing position restricting piece is provided on the main wall of the lid body, wherein the closing position restricting piece is tilted when a pressing force equal to or more than a predetermined value is applied. After the outflow cylinder has fallen down and is brought into contact with the closing position restricting piece, if a pressing force of a predetermined value or more is applied to the closing position restricting piece via the outflow cylinder, the closing position restricting piece tilts. Then, the outflow cylinder is further laid down, and the pressing force via the outflow cylinder is released. That the, the closed position restricting piece is brought into elastically restored, there is provided a container closure characterized in that.

It is preferable that the closing position restricting piece has a thin lower end, and is tilted by being swiveled around the thin lower end. In a preferred embodiment, the turning center axis of the outflow tube and the turning center axis of the outer cover extend substantially in parallel, and the turning center axis of the outer cover is larger than the turning center axis of the outflow tube. It is located below and radially outward. The outer lid has a circular top wall and a cylindrical skirt wall hanging down from a periphery of the top wall, and when the outer lid is swung from the closed position to the open position, an inner periphery of a lower end of the skirt wall is formed. When the outer lid is swung from the open position to the closed position, the lower end of the skirt wall or the inner peripheral surface at the lower end interferes with the tip of the outflow tube. . It is preferable that a gripping projection projecting outward in the radial direction is provided at a position of the upper end of the outer peripheral surface of the skirt wall of the outer lid that is farthest from the center axis of rotation of the outer lid.

According to another aspect of the present invention, the following improvement is made to the above-described container lid proposed by the present inventors, that is, to enable the outer lid to be used as a measuring cup. It has been found that the above technical problem can be achieved by arranging the measurement symbol on the outer lid.

That is, in another aspect of the present invention, a container lid for achieving the above-mentioned other technical problems includes a lid main body attached to the mouth and neck of the container, an outflow cylinder having a through-flow passage, and an outer lid. The lid body has a main wall that covers the top surface of the mouth and neck of the container, and an outflow hole is provided in the main wall, and the outflow cylinder is pivotable on the upper surface of the main wall of the main body. In the open position extending upward from the outflow hole of the main wall, the through-outflow passage is communicated with the inside of the container through the outflow hole, and when the through-outflow passage is turned down to the closed position, the through-outflow passage is opened. An outflow passage is made not to communicate with the outflow hole, and the outer lid is mounted on the lid body so as to be pivotable between a closed position and an open position, and the main wall of the lid body is in the closed position. And in the open position, exposes the main wall of the lid body and the outflow cylinder, and It is disposed metering sign in,

On the other hand, the closed position regulating piece 34 in the illustrated embodiment extends obliquely rearward (ie, rightward in FIG. 2) upward from the upper surface of the main wall 12. If desired, the closing position restricting piece 34 can be inclined upward (ie, leftward in FIG. 2). The closing position restricting piece 34 also has a flat plate shape as a whole, but the closing position restricting piece 34 has a thin lower end 35 extending over the entire lower end thereof. As will be further described later, when a pressing force equal to or more than a predetermined value is applied to the upper edge of the closed position restricting piece 34, the closed position restricting piece 34 is centered on the thin bottom end 35 as shown by a two-dot chain line 34A in FIG. In FIG. 2, it is tilted clockwise, and when the pressing force is released, it is restored to the state shown by the solid line in FIG.

An upper annular shoulder surface 36 is formed on the outer peripheral surface of the skirt wall 14 of the lid body 4. The skirt wall 14 is located above the annular shoulder surface 36.
An annular locking ridge 38 is formed on the outer peripheral surface of. A portion of the outer peripheral surface of the skirt wall 14 below the annular shoulder surface 36 has unevenness extending in the axial direction, that is, a knurl 40.
Are formed. On the other hand, an annular holding ridge 42 is formed on the upper part of the inner peripheral surface of the skirt wall 14. A female thread 44 is formed at an intermediate portion of the inner peripheral surface of the skirt wall 14.

The outer lid 8 integrally formed with the lid main body 4 has a circular top wall 46 and a cylindrical skirt wall 48 hanging down from the periphery of the top wall 46. An annular locking ridge 50 is formed at the lower end of the inner peripheral surface of the skirt wall 48. As can be clearly understood by referring to FIG. 3, the outer lid 8 is integrally connected to the lid main body 4 via the hinge connecting means 54. The hinge connecting means 54 is disposed between a specific angle portion at the lower end of the outer peripheral surface of the skirt wall 48 of the outer lid 8 and a specific angle portion of the annular shoulder surface 36 of the skirt wall 14 of the lid body 4. 4 with the outer lid 8 in FIG.
2 and a closed position indicated by a two-dot chain line 8A in FIG. 2 and an open position indicated by a solid line in FIGS. The hinge connection means 54 shown in the figure, which is well known to those skilled in the art, resiliently biases the outer lid 8 to the open position when the outer lid 8 is turned from the closed position to the open position beyond a required angle, Further, when the outer lid 8 is turned beyond the required angle from the open position to the closed position, the outer lid 8 is elastically biased to the closed position. The outer lid 8 is shown in FIGS.
When it is positioned at the closed position shown by the two-dot chain line 8A, an annular locking ridge 50 formed on the inner peripheral surface of the skirt wall 48 of the outer lid 8 is formed on the outer peripheral surface of the skirt wall 14 of the lid main body. The outer lid 8 is maintained in the closed position by elastically overcoming and engaging below the annular locking ridge 38.

As shown in FIG. 1, a specific angular position at the upper end of the outer peripheral surface of the skirt wall 48 of the outer lid 8, that is, an angular position diametrically opposite to the angular position where the hinge connecting means 54 is provided. Is formed with a gripping projection 52 protruding outward in the radial direction. At the angular position where the grip projection 52 is formed, the skirt wall 4
The outer peripheral surface of 8 is formed with a recessed portion 53 having an outer diameter somewhat smaller than other portions.

Continuing the description with reference to FIG. 1, a measuring symbol 57 is formed on the outer peripheral surface of the skirt wall 48 of the outer lid 8. The measuring symbol 57 may be, for example, a plurality of ridges extending in the circumferential direction at a required interval in the axial direction.
If desired, a metering symbol 57 can be formed on the inner peripheral surface of the skirt wall 48. As will be described later, when the liquid (for example, the cleaning liquid) contained in the container is discharged while being measured, the liquid is once discharged into the outer lid 8 and measured by referring to the measurement symbol 57. Can be. In order to be able to easily recognize the relationship between the amount of liquid discharged into the outer lid 8 and the measurement symbol 57, the outer lid 8 formed integrally with the lid main body 4 is transparent or translucent. Preferably, there is. Outer lid 8 molded together with lid body 4
Is non-transparent, in order to make the relationship between the amount of liquid discharged into the outer lid 8 and the measurement symbol 57 recognizable,
It is desired that the metering symbol 57 be formed on the inner peripheral surface of the skirt wall 48.

The description will be continued with reference to FIGS.
The outflow cylinder 6 has a base 58 and an extension 60. As clearly shown in FIG. 2, the outflow cylinder 6 has a base 58 and an extension 6.
A through-outflow channel 62 extending through 0 is formed. The cross-sectional shape of the through-flow passage 62 may be an appropriate shape such as an elliptical shape. The outer shape of the base portion 58 may be a substantially cylindrical shape extending in a direction perpendicular to the paper surface of FIG. 2, and the outer shape of the extending portion 60 may be an elliptical cylindrical shape or a substantially cylindrical shape extending substantially perpendicular to the base portion 58. The outer shape of the base portion 58 corresponds to the upper surface shape of the seat portion 22 formed on the main wall 12 of the lid body 4. A cylindrical shaft portion 64 is formed on both end surfaces of the base portion 58. Such an outflow cylinder 6 has its shaft portion 64 formed on the inner surface of a pair of mounting walls 28 formed on the main wall 12 of the lid main body 4.
Forcibly inserted into the cover main body 4 through the guide recess 31 so that the center axis 66 of the shaft portion 64 (and the bearing hole 30) is used as the center axis of rotation.
As will be further mentioned later, the outflow tube 6 is selectively located in an outflow position shown by a solid line in FIGS. 1 to 3 and a closed position shown by a two-dot chain line 6A in FIGS. At the boundary between the base portion 58 and the extending portion 60 of the outflow tube 6, a plate-like projection 68 projecting rightward in FIG. 2 when the outflow tube 6 is at the outflow position is formed. When the outflow tube 6 is turned from the outflow position to the closed position, the lower surface of the extending portion 60 of the outflow tube 6 is brought into contact with the closed position restricting piece 34 formed on the main wall 12 of the lid body 4. When the outflow cylinder 6 is swung from the closed position to the outflow position, the plate-like projection 68 of the outflow cylinder 6 is moved.
Abuts against the upper surface of the outflow position restricting piece 32 formed on the main wall 12 of the lid body 4, thereby preventing the outflow cylinder 6 from further turning clockwise in FIG. 3 beyond the outflow position. As clearly understood by referring to FIG. 2, when the outflow tube 6 is positioned at the outflow position, a through-outflow channel 62 formed in the outflow tube 6 is formed in the main wall 12 of the lid body 4. Directly connected to the outflow hole 16. When the outflow tube 6 is positioned at the closed position indicated by the two-dot chain line 6A, the through-outflow channel 62 of the outflow tube 6 is separated from the outflow hole 16 and the seat portion 22 provided around the outflow hole 16 is moved to the seat 22. The contacted outer surface of the outflow tube 6 closes the outflow hole 16.

Continuing the description with reference to FIG. 2, in the illustrated embodiment, the outflow tube 6 is swiveled about a swivel center axis 66, and the tip of the outflow tube 6 is indicated by a dashed line during such swirling. Draw a trajectory X shown. On the other hand, the outer lid 8 is turned around the turning center axis 56. At the time of such turning, the point at the lower end of the inner peripheral surface of the skirt wall 48 that is furthest away from the turning center axis 56 is a locus Y shown by a chain line.
Draw. As can be clearly seen from FIG. 2, the pivot center axis 66 and the pivot center axis 56 are mutually parallel, and the pivot center axis 56 is positioned below and radially outward from the pivot center axis 66. I have. When the outer lid 8 is turned from the closed position to the open position, as understood by comparing the trajectory X and the trajectory Y shown in FIG.
The inner peripheral surface of the lower end of the skirt wall 48 of the outer lid 8 interferes with the tip of the outflow tube 6. Accordingly, the outflow cylinder 6 is also swung from the closed position to the outflow position in association with the turning of the outer lid 8. When the outer lid 8 is turned to the position shown by the two-dot chain line 8B and the outflow tube 6 is turned to the outflow position shown by the solid line, the plate-like projection 68 of the outflow tube 6 is formed on the main wall 12 of the lid body 4. The outflow tube 6 contacts the upper surface of the outflow position regulating piece 32, thereby preventing the outflow cylinder 6 from further turning clockwise in FIG. Therefore, after a while
The outer cover 8 is separated from the outflow tube 6, the outflow tube 6 is left at the outflow position, and the outer cover 8 is turned to the open position.

When the outer lid 8 is pivoted from the open position to the closed position, when the outer lid 8 is pivoted to the position shown by the two-dot chain line 8C in FIG.
(In other words, at least a large part of the outflow tube 6 enters the skirt wall 48 of the outer lid 8),
The lower end of the skirt wall 48 or the lower end of the inner peripheral surface of the outer lid 8 abuts on the left edge of the tip of the outflow tube 6 in FIG. Therefore,
When the outer lid 8 is further turned, the outflow cylinder 6 is also turned from the outflow position toward the closed position indicated by the two-dot chain line 6A. When the outflow cylinder 6 is turned to the closed position indicated by the two-dot chain line 6A, the extending portion 60 of the outflow cylinder 6 is extended.
The lower surface of the outlet cylinder 6 is brought into contact with a closed position restricting piece 34 formed on the main wall 12 of the lid main body 4, thereby restricting the outflow cylinder 6 from further turning counterclockwise in FIG. Therefore, after that, the outflow tube 6 is left at the closed position, and the outer lid 8 is turned to the closed position.

The trajectory X drawn by the tip of the outflow cylinder 6 and the trajectory Y drawn by the point at the lower end of the inner peripheral surface of the skirt wall 48 of the lid body 8 which is furthest away from the center axis 56 are shown in FIG.
As clearly shown in FIG. 5, when viewed in the direction in which the outflow tube 6 turns from the closed position to the outflow position, the outflow tube 6 intersects somewhat upstream from the closed position of the outflow tube 6 and somewhat upstream from the outflow position of the outflow tube 6. It is preferable that the setting is made. In such a case, when the outer lid 8 is pivoted from the closed position shown by the two-dot chain line 8A in FIG. 2 to the open position shown by the solid line in FIG. While turning from the position shown by the two-dot chain line 8B to the position shown by the two-dot chain line 8C in FIG.
And / or the outflow tube 6 is somewhat elastically deformed so that the outer lid 8
Is separated from the outflow tube 8. Also, the outer lid 8 is shown in FIG.
When the outer lid 8 is turned from the open position shown by the solid line to the closed position shown by the two-dot chain line 8A in FIG. 2, the outflow cylinder 6 is closed by the two-dot chain line 6A in FIG. After being swung to the position, the outer lid 8 and / or the outflow tube 6 are somewhat elastically deformed, and the outer lid 8 is separated from the outflow tube 6.

Thus, when the outer lid 8 is in the open position shown by the solid line in FIG. 2, the outflow cylinder 6 is independently and accidentally turned to the closed position shown by the two-dot chain line 6A in FIG. , Outer lid 8
Is turned from the open position to the closed position.
Only when it is turned to the position shown by the two-dot chain line 8D, it is brought into contact with the outflow cylinder 6. As clearly understood by referring to the trajectory X and the trajectory Y, when the outflow cylinder 6 is at the position indicated by the two-dot chain line 6A and the outer lid 8 is at the position indicated by the two-dot chain line 8D, The mutual interference between the skirt wall 48 of the outer lid 8 and the outflow cylinder 6 is considerably large. Therefore, the outflow cylinder 6 is further moved from the position indicated by the two-dot chain line 6A in FIG.
In the case where it is not possible to turn counterclockwise at
Unless the outer lid 8 and / or the outflow cylinder 6 are elastically deformed by applying a considerable force to the outer lid 8 and / or the outflow cylinder 6, the outflow cylinder 6 cannot be moved into the outer lid 8 to pivot the outer lid 8 to the closed position,
The turning movement of the outer lid 8 becomes considerably difficult, if not impossible. However, in the illustrated container lid constructed in accordance with the present invention, the closing position restricting piece 34 for restricting the outflow cylinder 6 to the closed position 6A as described above extends obliquely upward in a predetermined direction. When a force equal to or more than a predetermined value is applied to the rim, as shown by a two-dot chain line 34A in FIG. 2, the tip is tilted about the thin bottom end portion 35, so that the outflow cylinder 6 is moved counterclockwise in FIG. Chain line 6
The swivel is moved to the position indicated by B, whereby the amount of mutual interference between the skirt wall 48 of the outer lid 8 and the outflow cylinder 6 is reduced or eliminated. Therefore, even if the outflow cylinder 6 is accidentally turned to the closed position indicated by the two-dot chain line 6A in FIG.
It can be pivoted to the closed position indicated by A. When the outer lid 8 is turned to the closed position, the outer lid 8 is separated from the outflow tube 6, so that the closed position restricting piece 34 is elastically restored to the original state, and the outflow tube 6 is shown by a two-dot chain line 6A in FIG. To the closed position indicated by.

Continuing with reference to FIG. 2, in the illustrated embodiment, the inner cap 10 is combined with the lid body 4 before the container lid 2 is applied to the container 70. This inner plug 1
0 includes a circular bottom wall 72 and a cylindrical side wall 74 extending upward from the periphery of the circular bottom wall 72. A pull ring 76 is connected to the inner peripheral surface of the side wall 74. A thin flange 78 protruding radially outward is formed at the upper end of the outer peripheral surface of the side wall 74. Such an inner plug 10 is relatively weak because the thin flange 78 is elastically engaged with an annular holding projection 42 formed on the upper surface of the inner peripheral surface of the skirt wall 14 of the lid body 4. So that it can be easily separated with a small force,
It is held by the lid body 4.

As shown in FIG. 2, the container lid 2 in which the inner stopper 10 is combined and the outer lid 8 is located at the closed position is
It is attached to the mouth and neck 80 of a container 70 that can be formed from a suitable synthetic resin such as polyethylene terephthalate. The mouth and neck portion 80 of the container 70 has a substantially cylindrical shape, and an external thread 82 is formed on the outer peripheral surface thereof. The container lid 2 is attached to the mouth and neck 80 by fitting the lid main body 43 to the mouth and neck 80 and rotating it in the closing direction, ie, clockwise as viewed from above in FIG. Skirt wall 1 of lid body 4
When the female thread 44 formed on the inner peripheral surface of the cover 4 is screwed into the male thread 82 of the mouth-and-neck portion 80, the inner plug 10 combined with the lid body 4 has two points in FIG. As shown by the dashed line, it is slightly raised relative to the lid body 4 by abutting on the top surface of the mouth and neck portion 80, and between the hanging wall 26 of the lid body 4 and the top surface of the mouth and neck portion 80. Gripped and its skirt wall 14
Is brought into close contact with the inner peripheral surface of the mouth and neck portion 80. If desired, the skirt wall 14 of the lid body 4 may be provided with a tamper-evident skirt portion of an appropriate form, or the entire container lid 2 may be covered with a shrink film in order to impart so-called tamper-evident characteristics. .

For example, when the contents of the container 70 which is a liquid beverage is to be drunk, the knurls 4 on the skirt wall 14 of the lid body 4 are
A finger is put on the outer cover 8 to rotate the outer lid 8 in the opening direction, that is, counterclockwise as viewed from above in FIG. As a result, since the female thread 44 of the lid body 4 is moved along the male thread 82 of the mouth-neck part 80, the lid body 4 (therefore, the outer lid 8 and the outflow cylinder 6) is raised with rotation. Since only the inner plug 10 is assembled to the lid body 4 so as to be easily detached with a small force as described above, the inner plug 10 is detached from the lid body 4 and remains in the mouth and neck portion 80. Thereafter, the user puts the finger on the pull ring 76 and removes the inner plug 10 from the neck and neck 8.
Then, the mouth and neck 80 is opened. Next, the container lid 2 is attached again to the mouth and neck 80 from which the inner stopper 10 has been removed,
That is, the cover body 4 is fitted to the mouth and neck portion 80 and rotated in the closing direction, and the female thread 44 formed on the skirt wall 14 of the cover body 4 is screwed to the male thread 82 of the mouth and neck portion 80. . Thus, the annular hanging wall 26 formed on the lower surface of the main wall 12 of the lid body 4 is brought into contact with the top surface of the mouth-neck portion 80, thereby sealing the mouth-neck portion 80. Thereafter, when the outer lid 8 is pivoted to the open position shown by the solid line in FIGS. 1 and 2 around the pivot center axis 56, the inner peripheral surface of the lower end of the skirt wall 48 of the outer lid 8 becomes the tip of the outflow cylinder 6. The outflow cylinder 6 is also swung from the closed position to the outflow position accompanying the turning of the outer lid 8. When the outer lid 8 is turned to the position shown by the two-dot chain line 8B, the outflow tube 6 is turned to the outflow position shown by the solid line, and the plate-like projection 68 of the outflow tube 6 comes into contact with the upper surface of the outflow position regulating piece 32. At the same time, the base 58 of the outflow tube 6 comes into contact with the front surface of the outflow position regulating piece 32, thereby preventing the outflow tube 6 from further turning clockwise in FIG. When the outer lid 8 is further turned clockwise from the position shown by the two-dot chain line 8B, the outer lid 8 and / or the outflow cylinder 6 are elastically deformed, so that the outer lid 8 is separated from the outflow cylinder 6 and the outflow cylinder 6 Is left at the outflow position, and the outer lid 8 is swung to the open position. Outflow cylinder 6
Extends upward from the outflow hole 16 of the main wall 12 at the outflow position, and the through-outflow channel 62 is
It is communicated within 0. Therefore, when the tip end of the outflow cylinder 6 is gripped by the mouth and sucked, the downstream side of the check valve 20, that is, the upper side becomes negative pressure, and the thin pieces 20a and 20b of the check valve 20 are bent upward in FIG. The check valve 20 is opened. Thereby, the contents contained in the container 70 are:
The liquid is discharged through the outflow hole 16 and the through-outflow path 62. If desired, the main portion of the container 70 can be somewhat crushed to facilitate the discharge of the contents from the container 70. After drinking the required amount of beverage, when the suction of the outflow cylinder 6 or the crushing of the main part of the container is stopped, the two thin pieces 20 a and 2 of the check valve 20 are stopped.
Ob is restored downward in FIG. 2 by its own elastic force, and the check valve 20 is closed. Then, the turning center axis 5
The outer lid 8 is pivoted to the closed position shown in FIGS. At this time, when the outer lid 8 is turned to the position shown by the two-dot chain line 8C in FIG. 2, the lower surface of the skirt wall 48 or the lower end of the inner peripheral surface of the outer lid 8 comes into contact with the tip of the outflow cylinder 6, Accordingly, when the outer lid 8 is further turned, the outflow cylinder 6 is also turned from the outflow position to the closed position indicated by the two-dot chain line 6A. Outflow cylinder 6 is shown in FIG.
2, the lower surface of the extending portion 60 of the outflow cylinder 6 is brought into contact with the closed position restricting piece 34 formed on the main wall 12 of the lid body 4 when it is turned to the closed position indicated by the two-dot chain line 6A in FIG. This further restricts the outflow tube 6 from turning further counterclockwise. When the outflow tube 6 is located at the closed position indicated by the two-dot chain line 8A, the through-outflow channel 62 of the outflow tube 6 is separated from the outflow hole 16 and
The outer surface of the outflow tube 6 that is brought into contact with the seat portion 22 disposed around the outflow hole 16 closes the outflow hole 16. Thus, the discharge of the contents through the outflow tube 6 is sufficiently reliably sealed. Accordingly, the check valve 20 can be omitted if desired. The outer lid 8 is further pivoted to the closed position shown by the two-dot chain line 8A in FIG.

The opening / closing pivoting movement of the outer lid 8 can be performed by putting a finger on a gripping projection 52 provided at the upper end of the outer peripheral surface of the skirt wall 48. The following facts should be noted in this regard. That is, it may be intended to form a gripping protrusion at the lower end of the outer peripheral surface instead of the upper end of the outer peripheral surface of the skirt wall 48. When detached from the outflow tube 6 and when the outer lid 8 is brought into contact with the outflow tube 6, the finger hung on the gripping projection is moved to the tip of the outflow tube 6 through which the liquid contained in the container 70 flows out. There is a risk of contact. On the other hand, if the grip projection 52 is formed on the upper end portion of the outer peripheral surface of the skirt wall 48, there is no possibility that the finger touches the tip of the outflow cylinder 6 on the grip projection 52.

When the liquid contained in the container 70 is a washing liquid or the like, and it is desired to measure and discharge a required amount,
The following operations can be performed using the outer lid 8 as a measuring cup. First, the outer lid 8 is turned from the closed position shown by the two-dot chain line 8A in FIG. 2 to the position shown by the two-dot chain line 8B in FIG. 2, and the outflow cylinder 6 is positioned at the outflow position. Next, the container 70 is tilted to bring the container 70 and the container lid into the state shown in FIG. Thereafter, for example, the main part of the container 70 is crushed to discharge the liquid from the container 70 into the outer lid 8. At this time, the discharge amount is measured with reference to the measurement symbol 57 provided on the outer lid 8. After the required amount of liquid has been discharged, for example, the outer lid 8 itself is maintained in the state shown in FIG. 7, and the container 70 and the lid main body 4 and the outflow cylinder 6 in the container lid are rotated counterclockwise in FIG. Then, the outflow cylinder 6 is detached from the outer lid 8 by turning, and then the outer lid 8 is appropriately tilted to discharge the liquid present in the outer lid 8 to a required place.
