On the outer peripheral surface on the lower end side of the cylindrical portion 24a in the stopper main body 24, the other screwing screw portion 22b is screwed in correspondence with the screwing screw portion 22a of the drinking mouth member 15.

The above-described screwing screw portions 22a and 22b allow the plug body 16 to be in an open state in which the opening portion 15m of the drinking mouth member 15 is allowed to be opened and a closed state in which the opening portion 15m is allowed to be closed. It is screwed into a screw pitch that moves by screw feed in approximately half rotation (see FIGS. 3 and 7).
Specifically, when the plug body 16 is rotated approximately half a turn (approximately 180 degrees), the plug body 16 is moved in the vertical direction L by approximately 2.5 mm to approximately 3 mm. Screwed.

The lid body 23 and the plug body 24 are fitted into the tube portion 24a of the plug body 24 from below with respect to the receiving portion 23c of the lid body 23, and the engaging claw 23d of the receiving portion 23c is engaged with the tube portion 24a. The lid 23 and the plug main body 24 are fitted and fixed integrally by engaging with the stop hole 24b.
The packing 25A is fitted to a protruding portion 24c having a stepped shape formed on the lower end side outer peripheral portion of the cylindrical portion 24a (see FIG. 12).

A support portion 24e to which the outer peripheral portion of the reversing portion 25a in the packing 25A is pressed is formed on the outer peripheral portion below the protruding portion 24c of the cylindrical portion 24a.
The lower surface of the support portion 24e against which the outer peripheral portion of the reversing portion 25a is pressed is inclined to a tapered surface that gradually decreases from the outer peripheral side toward the inner peripheral side.
As the pressure of the storage space X in the container body 11 increases, the outer peripheral portion of the reversing portion 25a is pressed perpendicularly to the lower surface of the support portion 24e, so that higher water blocking performance can be ensured.

  12 is an enlarged explanatory view of a portion b in the water stop state by the packing 25A shown in FIG. 3, more specifically, FIG. 12 (a) is an enlarged cross-sectional view of the water stop state by the packing 25A of the plug body 16, and FIG. 3 is an enlarged cross-sectional view of a state in which a storage space X and an internal space Y are communicated with each other. FIG.

The reversing portion 25a of the packing 25A has a protruding state (see FIG. 12A) that protrudes upward toward the internal space Y of the plug body 24 in accordance with a change in the internal pressure of the storage space X in the container body 11. It is provided with flexibility that allows elastic displacement in the inverted state (see FIG. 12B) that protrudes downward in the opposite direction to the protruding state.
Under normal pressure, the reversing portion 25a maintains a projecting state in which the reversing portion 25a projects in an arc shape upward due to the restoring force of the reversing portion 25a itself.

A pressure adjusting hole 26 having a round shape in plan view is formed through the outer peripheral portion of the reversing portion 25a pressed against the support portion 24e in the thickness direction.
On the lower peripheral edge of the pressure adjusting hole 26, a convex protrusion 26 a that protrudes downward is formed continuously in the circumferential direction along the lower peripheral edge of the pressure adjusting hole 26. That is, the thickness of the peripheral portion of the pressure adjusting hole 26 is made thicker than the peripheral portion of the pressure adjusting hole 26.

As a result, even if the reversing operation of the reversing portion 25a is repeated many times, for example, cracks and cracks are hardly generated in the peripheral portion of the pressure regulating hole 26, and the pressure regulating action by the pressure regulating hole 26 is continuously obtained. In addition, it is possible to ensure the strength necessary to maintain airtightness and waterstop.
In the embodiment, an example in which one pressure adjusting hole 26 is formed has been described, but a plurality of pressure adjusting holes 26 may be formed as necessary.

When the above-described plug body 16 is screwed to the drinking mouth member 15 of the lower mouth member 13 fixed to the mouth portion 12 in the container body 11, the stopper body 24 of the stopper body 16 is connected to the drinking mouth member 15 of the lower mouth member 13. In addition, the screwing screw portions 22a and 22b are screwed together, and are rotated more than half a turn in the closing direction CL.
Since the outer peripheral portion of the packing 25A fitted to the plug main body 24 is pressed in a close contact state along the radially inner peripheral surface of the protruding portion 15k of the drinking mouth member 15 to close the communication impossible state, the plug is securely closed, and Can stop water.

  That is, in the closed state, the opening 25m of the drinking mouth member 15 in the lower mouth member 13 is closed by the packing 25A of the stopper body 24, so that the liquid stored in the storage space X of the container body 11 It is possible to prevent leakage from the opening 15m to the outside.

When the internal pressure of the storage space X in the container main body 11 is normal, the outer peripheral portion of the packing 25A is pressed against the support portion 24e of the plug main body 24 by the restoring force of the packing 25A itself.
Since the upper surface side peripheral portion of the pressure adjusting hole 26 formed in the outer peripheral portion of the packing 25A is also pressed in a state of being in close contact with the lower inclined surface of the support portion 24e, airtightness and water stoppage can be secured at the same time. (See the solid line in FIG. 12 (a)).

When the internal pressure of the storage space X in the container body 11 is higher than that at normal pressure, the outer peripheral portion of the packing 25A is strongly pressed against the lower inclined surface of the support portion 24e, and the upper peripheral side peripheral portion of the pressure adjusting hole 26 is also Since it is strongly pressed perpendicularly to the lower slope of the support portion 24e, it is possible to ensure higher airtightness and waterstop.
Therefore, even if the closed portable beverage container 10 is toppled, it is possible to reliably prevent the liquid stored in the storage space X of the container body 11 from leaking to the outside.

When the temperature of the liquid stored in the storage space X of the container body 11 is lowered and the internal pressure of the storage space X is lower than that at normal pressure, the reversing portion 25a of the packing 25A is reversed downward against the restoring force. (See the virtual line in FIG. 12A).
Furthermore, the reversal part 25a of the packing 25A is pulled downward, whereby a gap is generated between the outer peripheral part of the packing 25A and the lower slope of the support part 24e.

  The pressure adjusting hole 26 formed in the outer peripheral portion of the packing 25A is separated from the lower slope of the support portion 24e, and a gap is formed between the upper peripheral edge of the pressure adjustment hole 26 and the lower slope of the support portion 24e. Therefore, the storage space X of the container main body 11 and the internal space Y of the plug main body 24 are communicated with each other through the pressure adjusting hole 26 (see the solid line in FIG. 12B).

Since the internal space Y of the plug main body 24 communicates with the outside of the plug main body 24 through a ventilation path (not shown), the container main body 11 is stored from the internal space Y side of the plug main body 24 via the pressure adjusting hole 26. Intake of outside air is allowed toward the space X side.
When the internal pressure of the storage space X in the container main body 11 is restored to normal pressure by the intake air described above, the pressing force of the packing 25A against the protruding portion 15k of the lower cylindrical portion 15b in the drinking mouth member 15 returns to the normal pressure state. Therefore, the contact resistance when the plug body 16 is operated approximately half-turn in the opening direction OP is reduced, and the plug 16 can be easily opened by hand.

  When the internal pressure of the storage space X in the container body 11 returns to normal pressure, the reversing portion 25a of the packing 25A returns to a protruding state that protrudes upward by the restoring force of the reversing portion 25a itself, and the outer peripheral portion of the packing 25A And, since the upper surface side peripheral portion of the pressure adjusting hole 26 is pressed against the lower slope of the support portion 24e, airtightness and water-stopping property can be ensured.

  When the plug body 16 is rotated approximately halfway in the opening direction OP and the lower end portion of the lid body 23 in the plug body 16 is moved upward from the step portion 14e of the shoulder member 14 in the lower mouth member 13, the lid body 23 is supported by a wall portion 20b of a concave engagement portion 20 formed on the shoulder member 14 (see FIGS. 3 and 10A).

  On the other hand, when the plug body 16 is rotated approximately halfway in the closing direction CL and the inner periphery of the lower end side of the lid body 23 in the plug body 16 is engaged with the outer peripheral surface of the step portion 14e of the shoulder member 14 in the lower opening member 13. The lid body 23 of the plug body 16 is held concentrically with no backlash with respect to the shoulder member 14 of the lower mouth member 13.

When the plug body 16 is moved upward as described above, since the concave engagement portion 20 does not exist on the outer peripheral surface of the shoulder member 14 opposite to the concave engagement portion 20, the lid body 23 of the plug body 16 Between the lower end side inner periphery and the upper end side outer periphery of the upper cylindrical portion 14a in the shoulder member 14, a clearance S corresponding to the step between the upper cylindrical portion 14a and the stepped portion 14e is formed.
In other words, the clearance S allows the eccentric movement of the plug body 16 toward the front side Ff corresponding to the drinking hole projection hole 23a of the lid body 23 (see FIGS. 7 and 10B).

Next, a dispensing method for dispensing a liquid from the above-described portable beverage container 10 will be described.
When starting to pour out the liquid, the stopper 16 is screwed into the drinking mouth member 15 of the lower mouth member 13 fixed to the mouth 12 in the container main body 11, and the radial center of the opening 15m is the center. As the plug body 16 is operated approximately half a turn in the opening direction OP, and the plug body 16 is operated approximately half a turn, the screwing screw portion 22b of the plug body 16 is moved along the screwing screw portion 22a of the spout member 15. Move upward.
As a result, the plug body 16 can be screw-feeded by a movement amount that allows the opening of the opening 15m to be opened by relative movement between the screwing screw portions 22a and 22b.

  The plug body 16 is moved in a direction in which the packing 25A is separated from the protruding portion 15k of the spout member 15 by screw feeding by the screwing screw portions 22a and 22b, and the tightness of the packing 25A to the protruding portion 15k is released. Then, the opening 15m of the mouthpiece member 15 is opened (see FIGS. 5 to 7 and FIG. 9B).

  The plug body 16 starts rotating in the opening direction OP, and the plug body 16 shifts from a closed state in which the opening portion 15m is allowed to be closed to an open state in which the opening portion 15m is allowed to be opened. Accordingly, the drinking hole projecting hole 23a of the lid body 23 is changed from a communication impossible state in which communication with the opening 15m of the drinking hole member 15 is impossible to a communication allowable state in which communication with the opening 15m is allowed. Migrate at the same time.

  Thereby, at the same time that the opening 15m is opened, the drinking mouth protruding hole 23a of the lid 23 can be communicated with the opening 15m of the drinking mouth member 15 through the extraction path 15c1, and the container body 11 is stored. The inside and the outside of the container main body 11 can be communicated with each other in a communication permissible state in which the liquid stored in the space X is allowed to be dispensed.

The mouthpiece protrusion hole 23a of the lid body 23 is moved to the front side Ff that coincides with the mouthpiece 15c of the mouthpiece member 15 by approximately half rotation, and the mouthpiece 15c of the mouthpiece member 15 is made to protrude the mouthpiece of the plug body 16. It protrudes outward from the hole 23a.
Since the drinking mouth 15c of the drinking mouth member 15 protrudes further outward than the drinking mouth exposure part 23e of the lid body 23, it is possible to secure a protruding amount that allows direct drinking from the drinking mouth 15c.

  When the mouthpiece protrusion hole 23a of the lid body 23 is moved approximately half a rotation to the position of the front side Ff coinciding with the mouthpiece 15c of the mouthpiece member 15, the convex portion 23b of the lid body 23 in the plug body 16 is the shoulder member. 14 over the wall portion 20b of the concave engagement portion 20 and engages with the groove portion 20a, and the rotation of the drinking hole protruding hole 23a of the lid 23 is restricted to a position that coincides with the drinking hole 15c of the drinking hole member 15 ( (See FIG. 7, FIG. 10 (b), FIG. 11 (a)).

  After opening as described above, when the opened portable beverage container 10 is tilted to a desired angle at which liquid is allowed to be dispensed, the drinking hole projecting hole 23a of the lid 23 in the plug body 16, It is possible to prevent the position of the mouthpiece member 15 from the mouthpiece 15c in the lower mouth member 13 from being shifted in the circumferential direction, and the mouthpiece 15c of the mouthpiece member 15 is more outward than the mouth opening projection hole 23a of the lid 23. It can be kept protruding by a predetermined amount.

  If the portable beverage container 10 in the opened state is held in a posture in which the drinking mouth 15c of the drinking mouth member 15 is on the near side and tilted to a desired angle at which the liquid is poured out from the drinking mouth 15c, the container body 11 The liquid stored in the storage space X can be poured out from the drinking mouth 15c of the drinking mouth member 15 protruding outward from the drinking mouth protrusion hole 23a of the lid 23.

Since the drinking mouth 15c of the drinking mouth member 15 protrudes outward from the drinking mouth protrusion hole 23a of the lid 23, the liquid poured out from the drinking mouth 15c contacts the lid 23 or is poured out by the lid 23. Can be avoided, and liquid can be reliably poured out in the desired direction without splashing around.
For example, it is possible to directly drink from the drinking mouth 15c by pressing the user's mouth directly against the drinking mouth 15c or approaching the drinking mouth 15c.

  In addition, when the liquid stored in the storage space X of the container body 11 is poured out, the liquid stored in the storage space X is allowed to pass between the end portions on the side of the drinking mouth 15c in the screwing screw portion 22a. Since the liquid is guided toward the mouth 15c, the liquid can be smoothly poured out from the drinking mouth 15c of the drinking mouth member 15 without being hindered by the screwing screw portion 22a.

During the dispensing, when the internal pressure of the storage space X decreases as the storage amount of the liquid stored in the storage space X of the container body 11 decreases, the external pressure is reduced by the decrease in the internal pressure. While sucking in from 15d, it can pass through between the edge part by the side of the ventilation path 15d in the screwing screw part 22a, and can be made to flow in into the storage space X reliably.
Thereby, the inflow of outside air is not hindered by the screwing screw portion 22a, and can be more efficiently caused to flow into the storage space X of the container body 11, and the liquid stored in the storage space X of the container body 11 can be It is possible to smoothly pour out from the mouthpiece 15c of the mouthpiece member 15.

Next, when stopping the dispensing of the liquid, the plug body 16 is substantially half-turned (approximately 180 degrees) in the plugging direction CL while being screwed into the drinking hole member 15 of the lower port member 13, and the plug body 16. As a result, the screwing screw portion 22b of the plug body 16 is moved downward along the screwing screw portion 22a of the spout member 15.
As a result, the plug body 16 can be screw-feeded by a movement amount allowing the plugging of the opening 15m to be permitted by relative movement of the screwing screw portions 22a and 22b.

  The plug body 16 is moved in a direction in which the packing 25A is pressed against the protruding portion 15k of the spout member 15 by screw feeding by the screwing screw portions 22a and 22b, and the packing 25A is moved radially inward of the protruding portion 15k. Since it presses in the state closely_contact | adhered with respect to the surrounding surface and the opening part 15m of the drinking mouth member 15 is plugged, the extraction | pouring of a liquid can be stopped (refer FIGS. 1-3, FIG. 9 (a)).

  As described above, the plug body 16 is only operated approximately half a turn in the opening direction OP and the closing direction CL while being screwed into the drinking hole member 15 of the lower opening member 13 fixed to the opening 12 in the container body 11. Thus, the opening 15m can be opened and closed without removing the plug body 16.

In addition, there is no need to change the position and orientation of the hand that rotates the plug body 16 during the rotation operation, and the amount of rotation can be less than that of rotating the plug body 16 one or more times. The part 15m can be opened and closed more easily.
Furthermore, since the trouble of attaching and detaching the plug body 16 to and from the opening 15m of the mouthpiece member 15 can be saved, it is possible to immediately shift between an opened state in which liquid is poured out and a closed state in which dispensing is stopped. .

When the stopper body 16 is operated approximately half a turn in the closing direction CL, the mouth opening protrusion hole 23a of the lid body 23 is moved to the rear side Bb on the opposite side to the mouth opening 15c of the mouthpiece member 15 by approximately half rotation. The mouthpiece 15c of the mouthpiece member 15 is covered with a portion of the lid 23 opposite to the mouthpiece protrusion hole 23a.
The drinking hole protruding hole 23a of the lid body 23 is moved to the position of the rear side Bb coinciding with the protruding hole blocking part 15p of the drinking hole member 15 by approximately half rotation, and the drinking hole protruding hole 23a is moved to the protruding hole blocking part 15p. Since it engages, the drinking-mouth protrusion hole 23a of the cover body 23 can be reliably obstruct | occluded.

By covering the drinking mouth 15c of the drinking mouth member 15 with the lid 23, the drinking mouth 15c of the drinking mouth member 15 can be prevented from being exposed to the outside after the pouring is finished or during the pouring stop.
For example, foreign matters such as dust and dust can be reliably prevented from entering the container body 11 from the drinking mouth 15c, and human hands and fingers can also be prevented from touching the drinking mouth 15c, thus maintaining a hygienic state. be able to.

In the opened state, the liquid stored in the container body 11 in the portable beverage container 10 is poured out along the drinking mouth 15c of the drinking mouth member 15 in the direction coinciding with the drinking mouth 15c. When the container 10 is tilted to a desired angle at which the liquid is poured out from the drinking mouth 15c, it is possible to more positively prevent the liquid dispensing direction from changing to an unintended direction.
Thereby, it is possible to more positively prevent the liquid poured out from the drinking mouth 15c from being mistakenly poured out in an unintended direction and to be scattered around, and to reduce the loss of the liquid.

  When the plug body 16 is rotated approximately halfway in the opening direction OP, the convex portion 23b of the lid body 23 is given when the wall portion 20b of the concave engagement portion 20 is passed over and engaged with the groove portion 20a. Due to the uneven feel, the mouth 23 of the lid 23 has been rotated approximately halfway to the position coincident with the mouth 15 c of the mouth member 15 by the operation feeling given to the hand that rotates the stopper 16. Since it can be grasped, it is possible to prevent the plug body 16 from being unnecessarily rotated or insufficient.

  Further, when the portable beverage container 10 is tilted to an angle at which the liquid is allowed to be dispensed in a state in which the plug body 16 is substantially half-rotated to the open state, the movement corresponding to the clearance S is performed by the tilting operation. The entire plug body 16 is allowed to move eccentrically in a direction in which the groove 20a of the concave engagement portion 20 and the convex portion 23b of the lid body 23 are engaged with each other (FIGS. 7 and 7). 10 (b) and FIG. 11 (a)).

  Accordingly, the eccentric movement direction of the plug body 16 in the direction in which the engagement between the groove portion 20a and the convex portion 23b is allowed to coincide with the direction corresponding to the drinking mouth 15c of the drinking mouth member 15 in the lower mouth member 13. , Can be engaged more reliably.

The protrusion 23b of the lid 23 is engaged with the groove 20a in the shoulder member 14 at a position opposite to the drinking mouth 15c, and the drinking mouth protruding hole 23a of the stopper 16 is the drinking mouth 15c of the drinking mouth member 15. Therefore, it is possible to prevent the position of the lid body 23 of the lid body 23 from being shifted from the drinking hole projection hole 23a.
Thereby, the portable beverage container 10 is tilted to a desired angle at which the liquid is allowed to be dispensed, and the liquid is directly drunk from the drinking opening 15c of the drinking opening member 15 in the lower opening member 13, or poured into a container such as a cup. When doing so, it is possible to more reliably prevent the plug body 16 from rotating unexpectedly.

  In addition, the convex portion 23b of the lid body 23 in the plug body 16 is moved over the wall portion 20b of the concave engagement portion 20 of the shoulder member 14 in the lower mouth member 13 and engaged with the groove portion 20a, and the convex portion 23b is Since the above-described clearance S allows the operation of detaching from the groove 20a, the operation when the plug body 16 is rotated approximately halfway in the opening direction OP and the closing direction CL can be performed without any trouble (FIGS. 7 and 7). 10 (a) and FIG. 11 (b)).

When cleaning the inside of the container body 11, the screwing screw portions 22 a and 22 b are released from each other while the plug body 16 is rotated more than half a turn in the opening direction OP, and the plug body 16 is plugged. The main body 24 is extracted from the drinking mouth member 15.
If the lower end member 13 is separated from the mouth portion 12 of the container body 11 by releasing the screwing of the screwing screw portions 18a and 18b while rotating the drinking mouth member 15 in the opening direction OP, the container Since the entire mouth portion 12 of the main body 11 is opened, it is possible to easily clean the inside of the container main body 11.

In the above-described first embodiment, the example in which the water is stopped by the disk-shaped packing 25A having the reversing portion 25a and the pressure adjusting hole 26 has been described, but the water may be stopped by using the annular packing 25B.
FIG. 13 is an explanatory diagram of a water stop structure for stopping water at the annular packing 25B in the second embodiment.

  Specifically, an annular packing 25 </ b> B formed of a flexible elastic member is fitted to the protruding portion 24 c of the plug body 24 having a bottomed cylindrical shape in the plug body 16.

  When stopping the dispensing of the liquid, the plug body 16 is operated approximately half a turn in the closing direction CL while being screwed into the drinking mouth member 15 of the lower mouth member 13 in the mouth portion 12, and the plug body 24 of the plug body 16. Since the packing 25 </ b> B fitted to the pressing member 15 is pressed against the radially inward peripheral surface of the protruding portion 15 k of the drinking mouth member 15, the plug 25 </ b> B can be reliably closed and water-stopped.

As a result, it is possible to reliably prevent the liquid stored in the storage space X of the container body 11 from leaking from the opening 15m of the drinking mouth member 15 in the closed state, and the portable beverage container using the packing 25A of the first embodiment. 10 can provide substantially the same operation and effect as the tenth embodiment.
Moreover, since there are no holes or openings in the outer peripheral portion of the packing 25B, no leakage occurs in the outer peripheral portion.

  The present invention is not limited to the configuration of the above-described embodiment, but can be applied based on the technical idea shown in the claims, and many embodiments can be obtained.

  In the embodiment, the example in which the screw pitch of the screwing screw portions 22a and 22b is set to a screw pitch included in the range of about 2.5 mm to about 3 mm has been described. For example, the screw pitch may be changed to a screw pitch of about 3 mm or more, and the screw pitch is not limited to the embodiment as long as the screw feed movement can be performed in the plugged state and the closed state.
