Next, above the first valve body 15, that is,
The spout member 51 attached to the stopper cap 3 above the second liquid passage 33 will be described.

As shown in FIG. 3, the spout member 51 is formed by projecting a pipe-shaped spout 53 from a spherical boss 52 and providing an internal passage 60 penetrating the spout 53 and the boss 52. I have.

The internal passage 60 is provided with a longitudinal partition wall 77.
(Upper and lower portions when the drinking member 51 is in a horizontal position), and the upper space becomes an air inflow passage 78. However, the above-mentioned partition wall 77 may be omitted and only the internal passage 60 may be provided.

Further, on both sides of the boss portion 52, horizontal rotation shafts 54, 54 'are provided in a direction perpendicular to the drinking mouth 53 and horizontal, and both rotation shafts 54, 54' have a central angle of 90 degrees. The fan-shaped restriction pieces 55, 55 'having the same shape are attached in a posture having the same rotational phase. In addition, one restriction piece 5
A torsion coil spring 56 is mounted on a rotating shaft 54 'projecting from the outer surface of 5'.

The rotation shaft 5 of each of the restriction pieces 55 and 55 '
4 and 54 ′, the mounting posture of the two sides 55
a, 55b (see FIG. 7 (a)), the side surface 55a on the leading side of the rotational phase is defined as a regulating side surface, and the regulating side surface 55a is set in a posture in which the drinking mouth 53 is in the diameter direction.

The above-mentioned drinking spout 53 is connected to the rotating shaft 5.
The recess 57 is formed on the lower surface of the boss portion 52 in a state in which the boss portion 52 is rotated about one of the bosses 52 and 54 'and turned sideways on one side (see FIG. 1).
6 (c) is formed, and the rib 44 of the operating member 41 of the second valve body 38 fits into the recess 57. The surface of the recess 57 opposite to the side of the drinking port 53 is formed with an inclined cam surface 58 that gradually becomes shallower toward the opposite side of the recess 57. In other words, the inclined cam surface 58 is inclined such that the side of the recess 57 becomes higher (deeper) when the drinking mouth member 51 is turned sideways, and the rib 44 is formed in the recess 57 (that is, the upper portion of the inclined cam surface 58). Is engaged.

As shown in FIG. 3, the stopper cap 3 for supporting the drinking member 51 has a circular hole 59 for accommodating the boss 52 at the center, and the stopper cap 3 on the inner peripheral wall of the circular hole 59. On the rear side, a storage recess 61 whose peripheral wall side and upper surface side of the circular hole 59 are open is formed. Also, a vertical slit-shaped bearing portion 6 having a lower end opened at an inner peripheral wall at a position 90 degrees different from the position where the storage recess 61 is provided.

And a storage portion 65 of a water supply button 64 opened on the lower surface of the plug cap 3 outside the other bearing portion 62.

The spout member 51 has a boss 52
Is stored in the circular hole 59, and the spout 53 in a sideways state is stored in the storage recess 61 (FIG. 6).
(See (a)), the torsion coil spring 56 urges the drinking spout 53 in a direction in which the drinking spout 53 is turned half a turn from the side-down state and rises (see the arrow in FIG. 6C). When the spout 53 is in the lying state, there is a gap G between the spout 53 and the bottom surface of the storage recess 61 to allow the spout member 51 to move down (see FIG. 1).

The shaft end of one of the rotating shafts 54 faces a positioning plate 66 integrated with the stopper cap 3. The regulating piece 55 (similarly, only the regulating piece 55 will be described below with respect to the regulating piece 55 ′ as well).
(See FIGS. 2, 5 (a) and 7 (a)). In this case, the regulating piece 55 abuts on the upper surface of the support projection 19 at an arc portion near the regulating side face 55a, and when the drinking spout 53 is rotated by an operation from the outside in the direction in which the drinking spout 53 stands, the contact position is changed to the other side. An arc portion close to 55b is reached (see FIG. 7C).

On the other hand, the state in which the drinking mouth 53 is lying down (FIG. 5)
(See FIG. 5A), when pushed downward by an external operation, the operating piece 17 and the first valve body 15 integrated therewith are moved down while the restricting piece 55 and the support projection 19 are in contact with each other (FIG. 5).
(See the solid line in (b)).

As shown in FIG. 6, a water supply button 64 is slidably inserted in the horizontal direction outside the positioning plate 66. The water supply button 64 is engaged with the positioning plate 66 by a key portion 67 at its inner end to prevent the water supply button 64 from coming off, and is directed outward by a coil spring 68 interposed between the inner surface of the water supply button 64 and the positioning plate 66. It is urged to.

When the key portion 67 is engaged with the positioning plate 66, the key portion 67 comes into contact with the side surface of the regulating piece 55 behind the positioning plate 66 (see the solid line in FIG. 6B). The spout member 51 is prevented from trying to rise due to the spring force of the torsion coil spring 56.

The key portion 67 has an engagement recess 69 at its end, and when the water supply button 64 is pushed in by an external operation, the key portion 67 comes off the regulating piece 55 (FIG. 6 (b), the restriction piece 55 passes through the engagement recess 69. Thereby, the spout member 5
Numeral 1 rotates 90 degrees about the rotation shafts 54 and 54 ', and the spout 53 stands up (see a two-dot chain line in FIG. 6C).
The spout member 51 includes a regulating piece 55 integrated with the
Is held upright by contacting the lower surface of the.

As described above, the mode in which the spout member 51 rises and falls within a range of 90 degrees around the rotating shafts 54 and 54 ′ by an external operation,
The mode of moving up and down by the movement of the 54 ′ in the bearings 62, 62 ′ is an example of “an operation of two different modes” in the claims.

On the other hand, when the first liquid passage 13 is open, the second liquid passage 33 is closed, and conversely, the second liquid passage 33 is closed.
The mutual closing structure that closes the first liquid passage 13 when is in the open state includes the two regulating ribs 11 (see FIG. 3) formed inside the plug member 2 and the drinking member 51. Is realized by an engagement / disengagement structure with the restriction piece 55.

That is, the pair of support projections 19 formed on the operation piece 17 of the first valve body 15 are arranged so as to move up and down along the side surface of the regulating rib 11 (see FIG. 7A). . In the closed state in which the drinking mouth 53 of the drinking mouth member 51 is in the lying state, the circular arc portion of the regulating piece 55 on the regulating side 55a side is in contact with the upper surface of the support protrusion 19 (see FIG. ), FIG. 7 (a)).

The restricting rib 11 is located at a position lower than the position of the restricting side 55a in FIG. Further provided on the leading side of the rotation phase,
The support projections 19 are in contact with the side faces of the support projections 19 and are arranged in parallel.

The upper end surface 11a of the restricting rib 11 is formed at a height corresponding to the lower end of the arc portion of the restricting piece 55 when the drinking member 51 is at the upward movement position. In addition, the spout member 5
When 1 is in the downward movement position (see FIG. 7B), an interference side surface 11b that approaches and opposes the restriction side surface 55a of the restriction piece 55 is provided on the restriction rib 11.

Now, when the drinking member 51 is moved down by an external operation, as shown in FIG.
At 5, the operating piece 17 and the first valve body 15 integrated therewith are pushed down to open the first liquid passage 13. At the same time, the control piece 5
5 has a relationship in which the restriction side 55a is closely opposed to the interference side surface 11b of the restriction rib 11.

As described above, since the spout member 51 is urged in the rising direction by the torsion coil spring 56, the restricting side surface 55a is pressed against the interference side surface 11b by the spring force (FIG. 7 (b)). Arrows), both sides 55a, 1
Friction force is generated between 1b. As a result, the spout member 51 is prevented from moving up or rotating without permission, and is held at the lower movement position. For this reason, the second liquid passage 33
Are not released and are kept closed.

On the other hand, from the state of FIG.
As shown in FIG. 7 (c), the regulating piece 55 rotates without interfering with the regulating rib 11, erects the drinking port 53, and the inclined cam surface 58 pushes down the operating member 41, thereby causing the second movement.
The valve body 38 is opened, and the second liquid passage 33 is opened. When the drinking member 51 is moved downward with the second liquid passage 33 opened, the arc portion of the regulating piece 55 is
Since it interferes with the upper end surface 11a of the mouthpiece 1, the spout member 51 cannot be pushed in. Therefore, the first liquid passage 13 is not opened, and is maintained in a closed state.

The stopper A according to the first embodiment is as described above. In the closed state attached to the container 1, as shown in FIG. 1 and FIG. Is screwed to the opening of. At this time, the first valve body 1
The collar 16 of 5 is pressed against the packing 8 by the spring force of the valve spring 22 and closes the first liquid passage 13. The spout 23 of the first liquid passage 13 is connected to the closing portion 2 of the spout opening / closing member 24.
Closed by 5.

On the other hand, the second valve body 38 has an inner coil spring 48
The O-ring 39 is pressed by the lower portion 35 by the spring force of the valve spring 47 composed of
The liquid passage 33 is closed.

When the tap is used as a spout type, when the spout member 51 is pressed down with a fingertip, the spout member 51 moves down within the range of the gap G (FIG. 5B). reference). Then, the regulating piece 55 pushes down the support projection 19 of the operating piece 17. As a result, the engagement projection 21 is disengaged from the engagement recess 28 of the spout opening / closing member 24, so that the spout opening / closing member 24 is retracted by the spring force of the coil spring 32, and the engagement projection 21 contacts the inclined guide surface 29. The transition to the engagement with the engagement surface 30 is made via the contact. As a result, while the spout 23 is opened, the first valve body 15 integrated with the operating piece 17 is lowered, and the collar 16 is separated from the packing 8, and the first liquid passage 1 is opened.
3 is released. Then, when the container 1 is tilted, the liquid inside is poured out of the spout 23 into a cup or the like. When the drinking member 51 is pushed down as described above, the first
Since the second valve body 38 and its operating member 41 housed inside the valve body 15 simultaneously descend while keeping the valve closed state, the second valve body 38 is not opened.

Further, even if the spout member 51 is to be erected while the first liquid passage 13 and the spout 23 are open, the regulating piece 55 interferes with the regulating rib 11. Is prevented from rotating (see FIG. 7B). Therefore, the second liquid passage 33 is not opened.

Even when the container 1 is tilted and the liquid inside is poured out, the frictional force of the restricting piece 55 against the restricting rib 11 prevents the spout member 51 from moving due to its own weight. Even if the finger touches the water supply button 64, the second liquid passage 33 is not opened.

When the use as the pouring form is completed,
The operation unit 27 is pushed in to slide the spout opening / closing member 24 forward. Then, the engagement protrusion 21 and the engagement surface 30
Is disengaged, the operating piece 17 and the first valve body 15 integrated therewith return to the original state, the first liquid passage 13 is closed, and the spout 23 is closed.

If the user forgets to close the first liquid passage 13, the operation part 27 projecting backward becomes obstructive when a cup (not shown) is placed on the stopper. I can tell you. In the operation when the above-mentioned cup is put on the stopper, the operation unit 27 may be automatically pushed in and operated.

On the other hand, when the tap A is to be used as a direct drinking type, the water supply button 64 is pressed with a fingertip (FIG. 6B).
8), the spout member 51 is rotated 90 degrees by the spring force of the coil spring 56, and the spout 53 rises as shown in FIG.
5 comes into contact with the lower surface of the storage section 65 to maintain the upright state (see the two-dot chain line in FIG. 6C). At this time, the rotating shaft 54,
Reference numeral 54 ′ rotates at the upper ends of the bearing portions 62, 62 ′, and pushes down the operating member 41 by the inclined cam surface 58. When the operating member 41 is lowered, the second member integrated via the bias spring 50
The valve element 38 includes an inner coil spring 48 and an outer coil spring 49
The O-ring 39 separates from the lower portion 35 and overcomes the spring force of the valve spring 47 to open the second liquid passage 33. The lower end of the internal passage 60 of the spout member 51 is communicated with the second liquid passage 33 by standing up. At this time, the packing 4 is provided between the upper end of the first valve body 15 and the boss 52.
0 sealed.

In this state, if the mouth 53 is attached and the container 1 is tilted, the liquid inside can be directly drunk. In this case, even if the spout 53 is pushed in with a tongue or a fingertip, the regulating piece 55 of the spout member 51 interferes with the upper end of the regulating rib 11 (see FIG. 7C). Can not. Therefore, the first liquid passage 13 is not opened.

If the temperature of the liquid is higher than a certain level when the liquid is used in the above-mentioned direct drinking type, as shown in FIG. 9, the inner coil spring 48 overcomes the spring force of the bias spring 50 and 2 valve body 38 is pushed up, and the second liquid passage 33
It is closed so that it does not drink more than a certain temperature.

It should be noted that the second liquid passage 33 can be closed when the temperature of the liquid is lower than a certain level due to the characteristics of the inner coil spring 48, and can be closed when the temperature is outside the upper and lower temperature ranges. Is as described above.

(Second Embodiment) A stopper according to a second embodiment shown in FIGS. 10 to 12 includes a spout member 51 and a second valve body 3.
The structure such as 8 is slightly different from that described above. That is,
