Description

  The present invention provides, for example, a container with a plug body in which a container body that stores a liquid such as water or tea is detachably provided with a plug body that closes the opening of the container body, and the opening of the container with a plug body. It relates to a stopper method.

  As a container with a stopper that stores and transports liquids such as water and tea inside, for example, a stopper with a lid that covers the drinking mouth connected via a hinge is attached to the container body with a bottomed cylindrical body A portable beverage container has been proposed (see Patent Document 1).

  The plug body of Patent Document 1 is pivotally supported by a mounting portion mounted on the container body, and is engaged with a locking operation body that is locked to the lid body, and the locking operation body is rotated to hold the locking state. It has a lock mechanism composed of an operating body to be released.

  This locking mechanism is configured such that the user can easily open the lid simply by operating the operating body with a fingertip. Thereby, the portable beverage container of patent document 1 is improving the operativity concerning the opening operation of a stopper.

  In addition, as another container with a stopper, for example, a stopper formed separately from the container main body is screwed to the opening in the container main body having a bottomed substantially cylindrical body, thereby closing the opening. A portable beverage container has been proposed (see Patent Document 2).

  The portable beverage container configured as in Patent Document 2 has an advantage that it is easy to secure an opening of a desired size and the stopper body and the container body can be separated, so that the container body and the stopper body can be easily cleaned. was there.

By the way, in the case of a container with a stopper that is opened by pressing one operating body as in Patent Document 1, for example, in a state where the operating body is stored in a bag, the operating body is pressed by the stored item in the bag. Alternatively, when the operating body is pressed from the outside, there is a possibility that it is easily opened.
On the other hand, in the case of a container with a plug body as in Patent Document 2, since the plug body is screwed to the container body, even if a stored item in the bag or an external force from the outside acts, It does not open easily.

  However, in the case of a container with a plug body in which a plug body is screwed to the container body, it is necessary to rotate the plug body by a predetermined rotation angle with respect to the container body when opening or closing the container. For this reason, the container with a plug body in which the plug body is screwed to the container main body is easier to operate for opening and closing the plug body than the container with a plug body that can be opened by pressing one operation body. There was a problem of low.

  In view of the above-described problems, the present invention provides a container with a plug body that can improve the operability for opening and closing the plug body, and can prevent opening by an unintended external force, and a method for opening the container with a plug body. For the purpose.

  The present invention includes a substantially cylindrical bottomed container body having an opening at one end, a plug body that is detachably mounted to the opening of the container body, and a mounted state in which the plug body is mounted on the container body A container with a plug body that holds the holding means, and the holding means is provided in either the plug body or the container body, and the holding means receives a pressing operation by a user, A set of operation receiving parts supported so as to be slidable in an orthogonal direction substantially orthogonal to the direction in which the plug body is mounted on the container body, and a set of locked parts provided on the locked parts provided on the other side A locking portion; a biasing member that biases the locking portion toward the locked portion; and a slide restricting portion that restricts the sliding movement of the operation receiving portion. While sliding inward in the orthogonal direction, the orthogonal direction The locking portion is configured to press the locking portion toward the side, the locking portion is configured to be separated from the locked portion by pressing of the operation receiving portion, and the slide restricting portion is configured as the set of operation receiving portions. When a plurality of the operation receiving units are pressed substantially simultaneously, the operation receiving unit starts pressing the locking unit, and when only one of the set of operation receiving units is pressed, the operation A feature is that the slide movement of the reception unit is restricted.

  The locking portion can be configured separately from the operation receiving unit, or can be configured integrally with the operation receiving unit. Further, the locking portion can be configured to be locked to the locked portion by rotation about a predetermined rotation axis, or to be locked to the locked portion by sliding in the orthogonal direction. .

The said operation reception part can be set as the structure which contact | abuts and presses the latching | locking part comprised separately, or the structure which presses the connection location with the latching | locking part connected rotatably.
The inward side in the orthogonal direction refers to a direction toward the virtual center line side in the orthogonal direction when the central axis of the container with a stopper along the direction in which the stopper is attached to the container body is taken as the virtual center line.

  The plurality of operation receiving units are pressed substantially simultaneously means that the plurality of operation receiving units are pressed simultaneously or substantially simultaneously, or the plurality of operation receiving units are pressed one by one and the pressed operation reception is performed. The case where the pressing state of a part is maintained is said.

According to the present invention, it is possible to improve the operability related to the opening / closing operation of the plug body and to prevent the plug from being opened by an unintended external force.
Specifically, since the locking portion is locked to the locked portion by the urging force of the urging member, the container with a stopper securely holds the state where the stopper is mounted on the container body. Can do.

  In this state, when a plurality of operation receiving units of the set of operation receiving units are pressed substantially simultaneously by the user, the operation receiving unit sets the locking unit in the orthogonal direction against the biasing force of the biasing member. It can be pressed inward. Thereby, the container with a stopper can release the locking state between the locked portion and the locking portion, and can separate the stopper from the container body.

For this reason, the user can perform the operation of pressing the operation receiving unit and the operation of separating the plug body and the container body as a series of operations without changing the handle holding the container with the plug body. .
Furthermore, for example, when the stopper is provided with a holding means, the user holds the container with the stopper, the action of holding the stopper, the action of pressing the operation receiving unit, and the action of removing the stopper. It can be performed as a series of operations without changing the handle.

  On the other hand, for example, when the stopper is provided with holding means and the stopper is formed in a shape capable of coming into contact with the opening of the container body in the direction in which the stopper is attached to the container body, When the stopper is mounted, the opening of the container body can press the locking portion inward in the orthogonal direction against the biasing force of the biasing member. For this reason, the container with a stopper can be easily attached to the container body simply by pushing the stopper into the opening of the container body.

  Thereby, the container with a stopper can ensure good operability in the opening / closing operation of the stopper. Furthermore, since the plug body can be separated from the container body, the container with a plug body can facilitate cleaning of the container body and the plug body.

  For this reason, the container with a plug body has a good operability such as a container with a plug body that can be opened by a user operating a lock mechanism with a fingertip, and a plug body in which the plug body is screwed onto the container body. It can be provided with good maintainability such as an attached container.

  When only one of the set of operation receiving units is pressed, that is, when a plurality of operation receiving units are not pressed substantially simultaneously, the slide restricting unit restricts the slide movement of the operation receiving units. The container can prevent the operation receiving part from pressing the locking part.

  As a result, when a plurality of operation reception units are not pressed substantially simultaneously, for example, when one operation reception unit is pressed by a storage item in a bag in a state of being stored in a bag or the like, or when the operation reception unit is dropped on the floor, When one operation receiving part is pressed, the container with a stopper can prevent the operation receiving part from pressing the locking part inward in the orthogonal direction by an unintended external force, and the stopper is not opened unintentionally. It is possible to prevent the stopper from separating from the container body by preventing the stopper.

  Therefore, the container with a plug body can improve the operability for the opening / closing operation of the plug body and can prevent the plug from being opened by an unintended external force.

As an aspect of the present invention, the mounting direction is the direction in which the plug body is mounted on the container body, and the holding means is juxtaposed in the mounting direction or in the direction opposite to the mounting direction with respect to the operation receiving unit. A rotating body that is rotatably supported with the mounting direction as a central axis, and the operation receiving portion includes a protruding portion that protrudes toward the rotating body, and the protruding portion is loosely fitted to the rotating body. A pressing start position at which the operation receiving portion starts to press the locking portion, the slide restricting portion including the protrusion of the operation receiving portion and the rotating body. The first groove portion formed along the inner side in the orthogonal direction and the second groove portion formed along the intersecting direction intersecting the inner side in the orthogonal direction from the pressing start position. Can be formed.
The restriction groove can be a groove having an opening or a groove having a recess.

According to this invention, the container with a plug body can improve the operability for the opening / closing operation of the plug body and more reliably prevent unintentional opening.
Specifically, since the first groove portion of the restriction groove portion is formed along the inner side in the orthogonal direction, when all the operation reception portions are pressed substantially simultaneously, the operation reception portion is the first of the restriction groove portions. Movement can be started along one groove portion.

  And when the operation reception part reaches the pressing start position where the locking part starts to be pressed, the second groove part intersects the first groove part, so the protrusion of the operation reception part is the second groove part The rotating body can be pressed inward in the orthogonal direction while abutting against.

  At this time, since the second groove portion intersects the inner side in the orthogonal direction, which is the traveling direction of the protrusion, the pressure load on the inner side in the orthogonal direction acting on the rotating body is dispersed. The protrusion of the operation receiving unit can rotate the rotating body so that the second groove portion continuously appears on the inner side in the orthogonal direction.

  Thereby, the slide restricting part can further move the operation accepting part from the pressing start position to the inner side in the orthogonal direction. For this reason, the operation reception part can press the locking part against the urging force of the urging member, and can release the locked state between the locked part and the locking part.

  On the other hand, when only one operation receiving unit is pressed among the set of operation receiving units, when one pressed operation receiving unit reaches the pressing start position, the protrusion in one operation receiving unit moves the rotating body. Try to rotate.

  At this time, since the protrusions of the other operation receiving portions that are not pressed remain in the first groove portion, when the rotating body starts to rotate, it comes into contact with the first groove portion in the rotation direction of the rotating body. Become. For this reason, the slide restricting portion can restrict the rotation of the rotating body by the protruding portion of the operation receiving portion that is not pressed.

  Thereby, when only one operation reception part is pressed among a set of operation reception parts, the slide restricting part prevents the operation reception part from further moving inward in the orthogonal direction from the pressing start position. Thus, the operation receiving part can be prevented from pressing the locking part.

  For this reason, the container with a stopper can prevent the locked state between the locked part and the locking part from being released when the plurality of operation receiving parts are not pressed substantially simultaneously, for example. Can be reliably prevented.

  Therefore, the container with a stopper can prevent unintentional opening more reliably without impairing the operability of the opening operation of the stopper by the slide restricting part having the restriction groove part bent in the intersecting direction. it can.

As an aspect of the present invention, the operation receiving unit and the rotating body can be formed in a substantially thin plate shape having a thickness in the mounting direction.
According to the present invention, the container with a plug body can suppress the length of the plug body in the mounting direction, and can reduce the size of the plug body.

  For this reason, for example, in a container with a plug body in which portability is desired, the container with a plug body can reduce the ratio of the length of the plug body to the length of the container with a plug body in the mounting direction. it can. Thereby, the container with a stopper can ensure the desired storage space easily, without impairing portability.

  Further, as an aspect of the present invention, the holding means is provided in the plug body, and the locked portion is formed on the inner surface of the container body, and is inversely tapered toward the substantial center of the opening of the container body. And the locking portion of the plug can be formed in a shape that abuts on the reverse tapered portion.

According to this invention, the container with a plug can reliably prevent unintentional separation of the plug.
Specifically, by adopting a configuration in which the locking portion is in contact with the reverse taper portion, the stopper-equipped container moves the stopper in the orthogonal direction and plugs in the separation direction in which the stopper is separated from the container body. The movement of the body can be regulated at the same time.

  Thereby, the container with a stopper can ensure more stably the locked state of the locked part of the container body and the locking part of the stopper. For this reason, for example, even when an unintended load in the separation direction is applied to the plug body or an unintended load in the orthogonal direction is applied to the plug body, the container with the plug body is plugged from the container body. The body can be prevented from separating easily.

  Therefore, the container with a stopper can reliably prevent unintentional separation of the stopper by configuring the locked portion with a reverse tapered portion.

Further, as an aspect of the present invention, the operation receiving portion is shaped so as to protrude from the stopper body or the container body provided with the holding means in the locked state in which the locking portion is locked to the locked portion. Can be formed.
According to the present invention, the container with a stopper can further improve the operability of the opening operation, and can visually indicate the opening state and the closing state to the user.

  Specifically, since the operation receiving part protrudes from the plug body or container body provided with the holding means, the container with a plug body is used compared to the case where the operation receiving part does not protrude from the plug body or the container body. It is possible to visually indicate the pressed location to the person. For this reason, the user can hold the stopper or the container main body while pressing the operation receiving portion.

  For this reason, the container with a stopper can easily perform an operation of pressing the operation receiving unit and an operation of separating the stopper and the container body as a series of operations. Thereby, the container with a plug can further improve the operability of the plug opening operation.

Further, when the stopper is attached to the container main body, the operation receiving portion slides inward in the orthogonal direction, and when it is completely attached to the container main body, it slides outward in the orthogonal direction.
By sliding the operation receiving part so that it appears and disappears in this way, the container with a plug body does not protrude from the plug body or the container body when the plug is closed and the plug body is completely attached. Compared to the case, the user can easily make it visible.

In addition, for example, when taking out the container with a plug body stored in a bag, the container with a plug body can function a portion protruding from the plug body in the operation receiving unit as a portion where a user hooks a finger.
Therefore, the container with a stopper improves the operability of the opening operation by the operation receiving portion protruding from the stopper or the container body, and visually shows the opening state and the closing state to the user. It can be specified.

As an aspect of the present invention, the plug body or the container main body may be provided with a seal member that has elasticity and closes a gap between the container main body and the plug body.
According to the present invention, the container with a stopper can improve airtightness and watertightness, and can be configured to be suitable for storing a liquid, gas, or solid that does not like moisture.

  The present invention also includes a substantially cylindrical bottomed container body having an opening at one end, a plug body that is detachably mounted to the opening of the container body, and a mounting body in which the plug body is mounted. A stopper-opening method for a container with a stopper including a holding means for holding a state, wherein the holding is performed by a biasing force of a biasing member in the holding means provided in either the stopper or the container body. In a state where a set of locking portions of the means is locked to a locked portion provided on the other side, a plurality of the operations among a set of operation receiving portions of the holding means for receiving a pressing operation by a user When the receiving portions are pressed substantially simultaneously, the set of operation receiving portions is moved inward in an orthogonal direction substantially orthogonal to the direction in which the stopper is attached to the container body. Moving start step for sliding the When only one of the operation receiving units is pressed, the slide restricting unit of the holding unit presses the movement restricting step of restricting the slide movement of the operation receiving unit and the plurality of operation receiving units substantially simultaneously. In the case where the operation receiving unit is pressed, the locking unit is pressed by the operation receiving unit by a pressing step in which the operation receiving unit presses the locking unit inward in the orthogonal direction as the slide moves. And a separation step of separating from the portion.

  According to the present invention, it is possible to open the plug when a plurality of the operation receiving units are pressed at the same time in a set of operation receiving units, without impairing the operability of the opening and closing operation of the plug body, and without intention. Opening due to external force can be prevented.

  According to the present invention, it is possible to provide a container with a plug body and a method for opening the container with a plug body, which can improve the operability of the opening / closing operation of the plug body and prevent the plug from being opened by an unintended external force.

A state where the plug body 3 having such a configuration is mounted on the container body 2 will be described in detail with reference to FIGS. 3 and 9.
In a state where the plug body 3 is attached to the container body 2, the compression coil spring 150 of the plug body 3 biases the release button 160 toward the outside in the width direction X as shown in FIG. 3.

  For this reason, the semicircular portion of the release button 160 is exposed to the outside of the outer plug member 130 through the outer plug opening 132a. At this time, the protrusion 164 of the release button 160 is located outside the width direction X in the first groove portion 175a of the restriction groove 175, as shown in FIG.

  And the inner side press part 162 of the cancellation | release button 160 presses the button side contact part 142 of the latching member 140 toward the outer side of the width direction X with the urging | biasing force of the compression coil spring 150, as shown in FIG. . For this reason, the locking member 140 is restricted from rotating about the locking shaft portion 141 as a center of rotation, and the tip of the container-side contact portion 143 is outside the inner cylinder portion via the inner plug opening portion 122a. Will be exposed.

FIG. 13A shows a cross-sectional view taken along the line C-C when one release button 160 is pressed, and FIG. 13B shows a line BB when one release button 160 is pressed. An arrow sectional view is shown.

First, a case where an operation by a user who separates the stopper 3 from the container body 2 is received by a pair of release buttons 160 will be described with reference to FIGS. 10 and 11.
10A, when the user presses the release button 160 inward in the width direction X substantially simultaneously, the pair of release buttons 160 resists the urging force of the compression coil spring 150 in the width direction. Each slides toward the inside of X.

  When the release button 160 slides about 2 mm, the outer pressing portion 163 of the release button 160 contacts the button-side contact portion 142 of the locking member 140 and the release button as shown in FIG. The protruding portion 164 of 160 abuts on the first groove portion 175 a side end portion of the second groove portion 175 b of the restriction groove portion 175.

  Thereafter, when the user further presses the release button 160 substantially simultaneously, the protrusion 164 of the release button 160 causes the second groove portion 175a of the restriction groove 175 to move inward in the width direction X as shown in FIG. Press towards.

  At this time, since the second groove portion 175b is formed in a direction intersecting the inner direction of the width direction X, the regulating member 170 is planar with the top plate shaft portion 133 of the outer plug member 130 as the central axis. A load that rotates counterclockwise will act.

  When the restricting member 170 starts to rotate counterclockwise in plan view, the second groove portion 175b of the restricting groove 175 continuously appears in the movement direction of the protrusion 164 that moves inward in the width direction X. 160 is further slidable inward in the width direction X.

Accordingly, the inner pressing portion 162 of the release button 160 starts pressing the button side contact portion 142 of the locking member 140 toward the inner side in the width direction X against the urging force of the compression coil spring 150.
When the inner pressing portion 162 presses the button-side contact portion 142, the locking member 140 rotates inward in the width direction X with the locking shaft portion 141 as the rotation center, as shown in FIG. Start moving. Thereafter, the container-side abutting portion 143 is separated from the reverse tapered portion 33 of the drinking mouth member 30 and is in a state of being submerged in the inner plug opening portion 122a.

  Thereby, the portable beverage container 1 can release the locking state between the locking member 140 and the drinking mouth member 30. When the user pulls the stopper 3 upward in the state where the locked state is released, the stopper 3 and the container body 2 are separated, and the mouthpiece member 30 is exposed.

  Note that when the user releases the pressing of the release button 160 of the separated plug body 3, the release button 160 slides outward in the width direction X by the urging force of the compression coil spring 150.

  At this time, the protrusion 164 of the release button 160 rotates the regulating member 170 clockwise in plan view, so that the plug body 3 has a semicircular portion of the release button 160 as shown in FIG. The container main body 2 is exposed to the outside of the outer plug member 130 through the outer plug opening 132a, and the container-side contact portion 143 is exposed to the outside of the inner plug cylinder 122 through the inner plug opening 122a. The state is substantially the same as the state in which the plug body 3 is mounted on.

  On the other hand, when the plug body 3 separated as shown in FIG. 12A is attached to the container main body 2, as shown in FIG. Since the container side abutting portion 143 abuts, the locking member 140 starts to rotate inward in the width direction X with the locking shaft portion 141 as the center of rotation by pressing the stopper 3 downward.

  When the locking member 140 starts to rotate, the button-side contact portion 142 of the locking member 140 resists the urging force of the compression coil spring 150 so that the inner pressing portions 162 of the pair of release buttons 160 are moved in the width direction X. Press toward the inside almost simultaneously. For this reason, the restricting member 170 starts to rotate counterclockwise in plan view, and the release button 160 slides inward in the width direction X.

  Thereby, the container side contact part 143 is immersed in the inside plug opening part 122a, and the inside plug member 120 can be inserted into the inside of the drinking hole member 30. Thereafter, when the stopper 3 is further pressed downward, the locking member 140 is locked to the reverse tapered portion 33 by the urging force of the compression coil spring 150, and the mounting of the stopper 3 to the container body 2 is completed.

Next, the operation of the slide restricting unit when an operation by the user is received by one release button 160 will be described with reference to FIG.
As shown in FIG. 13, when the user presses one of the release buttons 160 (the release button 160 on the left side in FIG. 13) inward in the width direction X, the pressed release button 160 is compressed coil spring. It slides inward in the width direction X against the urging force of 150.

  When the release button 160 slides about 2 mm, the outer pressing portion 163 of the release button 160 comes into contact with the button-side contact portion 142 of the locking member 140, and the protrusion 164 of the release button 160 moves to the restriction groove portion 175. The second groove portion 175b contacts the first groove portion 175a side end.

  At this time, the other release button 160 (the right side in FIG. 13) has not received a pressing operation by the user, that is, has not been slid inward in the width direction X. The protrusion 164 remains positioned in the first groove portion 175a of the restriction groove 175.

  For this reason, the protrusion 164 in the other release button 160 abuts on the restriction groove 175 counterclockwise in a plan view, whereby the restriction member 170 is restricted from turning counterclockwise in a plan view. Then, by restricting the rotation of the restricting member 170, the one release button 160 is restricted from further sliding inward in the width direction X.

  Accordingly, since one release button 160 cannot press the locking member 140, the portable beverage container 1 is formed between the container-side contact portion 143 of the locking member 140 and the reverse taper portion 33 of the drinking mouth member 30. The locked state can be maintained.

The portable beverage container 1 and the method for opening the portable beverage container 1 that realize the operation as described above can improve the operability of the opening and closing operation of the plug body 3 and can prevent the opening due to an unintended external force. it can.
Specifically, since the locking member 140 is securely locked to the reverse tapered portion 33 of the drinking mouth member 30 by the urging force of the compression coil spring 150, the portable beverage container 1 is attached to the container body 2 by the plug body 3. Can be securely held.

  In this state, when the pair of release buttons 160 are pressed almost simultaneously by the user, the release button 160 presses the locking member 140 inward in the width direction X against the urging force of the compression coil spring 150. Can do.

Thereby, the portable beverage container 1 can release the locking state between the reverse tapered portion 33 of the drinking mouth member 30 and the locking member 140 of the plug body 3, and the plug body 3 is separated from the container body 2. Can do.
For this reason, the user performs the operation of pressing the release button 160 and the operation of separating the container body 2 and the plug body 3 as a series of operations without changing the handle holding the portable beverage container 1. Can do.

  On the other hand, when the stopper 3 is attached to the container body 2, the drinking mouth member 30 can press the locking member 140 inward in the width direction X against the urging force of the compression coil spring 150. . For this reason, the portable beverage container 1 can easily attach the plug 3 to the container main body 2 simply by pushing the plug 3 into the mouthpiece member 30.

  Thereby, the opening method of the portable beverage container 1 and the portable beverage container 1 can ensure good operability in the opening / closing operation of the plug body 3. Furthermore, since the plug body 3 can be separated from the container body 2, the portable beverage container 1 can facilitate cleaning of the container body 2 and the plug body 3 and the like.

  For this reason, the portable beverage container 1 has a good operability such as a portable beverage container that can be opened by a user operating a lock mechanism with a fingertip, and a portable beverage container in which a stopper is screwed onto the container body. Thus, it can be provided with good maintainability as described above.

  When only one of the pair of release buttons 160 is pressed, the regulating member 170 regulates the sliding movement of the release button 160. Therefore, the opening method of the portable beverage container 1 and the portable beverage container 1 is the release button. It is possible to prevent 160 from pressing the locking member 140.

  As a result, when the pair of release buttons 160 are not pressed substantially simultaneously, for example, when one release button 160 is pressed by an item stored in the bag in the state of being stored in a bag, or when the release button 160 is dropped on the floor, When one release button 160 is pressed, the opening method of the portable beverage container 1 and the portable beverage container 1 is to prevent the locking member 140 from being pressed inward in the width direction X by the release button 160. It is possible to prevent unintentional opening of the plug body 3 and prevent the plug body 3 from being separated from the container body 2.

  Therefore, the portable beverage container 1 and the method for opening the portable beverage container 1 can improve the operability of the opening / closing operation of the plug body 3 and can prevent the opening due to an unintended external force.

  In addition, a first groove portion 175a in which a restriction groove portion 175 of the restriction member 170 into which the protrusion 164 of the release button 160 is loosely fitted is formed to a pressing start position at which the release button 160 starts to press the locking member 140, and a pressing start position Since the portable beverage container 1 is formed integrally with the second groove portion 175b formed from the above, the operability required for opening and closing the plug body 3 can be improved and unintentional opening can be more reliably prevented. .

  Specifically, since the first groove portion 175a of the restriction groove portion 175 is formed along the inner side in the width direction X, when the pair of release buttons 160 are pressed substantially simultaneously, the release button 160 is moved to the restriction groove portion 175. It is possible to start moving along the first groove portion 175a.

  When the release button 160 reaches the pressing start position where the locking member 140 starts to press, the second groove portion 175b intersects the first groove portion 175a. The restricting member 170 can be pressed inward in the width direction X while being in contact with the second groove portion 175b.

  At this time, since the second groove portion 175b intersects the inner side of the width direction X that is the traveling direction of the protrusion 164, the pressing load on the inner side of the width direction X acting on the regulating member 170 is dispersed. Thus, the protrusion 164 of the release button 160 can rotate the restricting member 170 so that the second groove portion 175b appears continuously inside the width direction X.

  Thereby, the restricting member 170 can further move the release button 160 from the pressing start position to the inside in the width direction X. For this reason, the release button 160 can press the locking member 140 against the urging force of the compression coil spring 150, and the reverse tapered portion 33 of the drinking mouth member 30 and the locking member 140 of the plug body 3 The locked state can be released.

  On the other hand, when only one release button 160 of the pair of release buttons 160 is pressed, when one of the pressed release buttons 160 reaches the pressing start position, the protrusion 164 of one release button 160 causes the restricting member 170 to move. Try to rotate.

  At this time, since the protrusion 164 of the other release button 160 that is not pressed remains in the first groove portion 175a, when the restriction member 170 starts to rotate, the first groove portion 175a in the rotation direction of the restriction member 170. Will abut. For this reason, the stopper 3 can restrict the rotation of the restricting member 170 by the protrusion 164 of the other release button 160.

Thereby, the regulating member 170 can prevent the release button 160 from further moving inward in the width direction X from the pressing start position, and can prevent the release button 160 from pressing the locking member 140.
For this reason, when the pair of release buttons 160 are not pressed substantially simultaneously, the portable beverage container 1 can prevent the locked state between the reverse tapered portion 33 and the locking member 140 from being released, and the plug 3 can be opened. Can be reliably prevented.

  Therefore, the portable beverage container 1 can more reliably prevent unintentional opening without impairing the operability of the opening operation of the plug body 3 by the bent regulation groove 175 and the protrusion 164 of the release button 160. can do.

  Moreover, since the release button 160 and the regulating member 170 are formed in a substantially thin plate shape having a thickness in the vertical direction, the portable beverage container 1 can suppress the length of the plug body 3 in the vertical direction. The size of the body 3 can be reduced.

  For this reason, the portable beverage container 1 can reduce the proportion of the length of the plug 3 relative to the length of the portable beverage container 1 in the vertical direction. Thereby, the portable drink container 1 can ensure the desired storage space S easily, without impairing portability.

In addition, since the locking member 140 is configured to abut on the reverse tapered portion 33 of the mouthpiece member 30, the portable beverage container 1 can reliably prevent the plug 3 from being separated.
Specifically, since the locking member 140 is configured to abut on the reverse taper portion 33, the portable beverage container 1 can move the plug body 3 outward in the width direction X and move the plug body 3 upward. It is possible to regulate both movement and balance.

  Thereby, the portable drink container 1 can ensure more stably the latching state of the reverse taper part 33 of the drinking mouth member 30 and the latching member 140 of the stopper 3. For this reason, for example, even when an unintended load is applied to the plug body 3 or when an unintended load to the outside in the width direction X is applied to the plug body 3, the portable beverage container 1 is It is possible to prevent the plug body 3 from being easily separated from the container body 2.

  Therefore, the portable beverage container 1 can reliably prevent unintentional separation of the plug body 3 by adopting a configuration in which the locking member 140 contacts the reverse tapered portion 33 of the drinking mouth member 30.

  Moreover, in the state which attached the plug body 3 to the container main body 2, by having made it the release button 160 of the shape which protrudes from the plug body 3, the portable drink container 1 improves the operativity concerning opening operation more, An open state and a closed state can be visually indicated to the user.

  Specifically, since the release button 160 protrudes from the plug body 3, the portable beverage container 1 visually indicates the pressed position to the user as compared to the case where the release button 160 does not protrude from the plug body 3. Can be specified. For this reason, the user can hold the plug 3 while pressing the release button 160 when holding the plug 3.

  Thereby, the portable beverage container 1 makes it easier for the user to perform the operation of holding the stopper 3, the operation of pressing the release button 160, and the operation of separating the container body 2 and the stopper 3 as a series of operations. Therefore, the operability for the opening operation of the plug body 3 can be further improved.

  Further, when the stopper 3 is attached to the container main body 2, the release button 160 slides inward in the width direction X when the spout member 30 presses the locking member 140, and the attachment to the container main body 2 is completed. Then, it slides to the outside in the width direction X.

  Thus, the release button 160 does not protrude from the plug body 3 by the sliding movement so that the release button 160 appears and disappears. Compared to the case, the user can easily make it visible.

In addition, for example, when the portable beverage container 1 stored in a bag is taken out, the portable beverage container 1 can cause the semicircle portion of the release button 160 to function as a portion where the user hooks a finger.
Therefore, the portable beverage container 1 further improves the operability of the opening operation by the release button 160 that can be moved in and out of the plug body 3, and visually indicates the opened state and the closed state to the user. can do.

  In addition, since the plug body 3 includes the plug body side packing member 110 that has elasticity and closes the gap between the mouthpiece member 30 and the plug body 3, the portable beverage container 1 has improved airtightness and water tightness. It can be made and it can be set as the structure suitable for storing drinking water.

  Further, when the plug body 3 is attached to the container body 2, the plug body side packing member 110 is used when the plug body is screwed to the container body in order to make close contact with the inner surface of the inner layer restricting portion 22 in the container body 2. In comparison, twisting is less likely to occur and the container body can be stably adhered. As a result, the plug-side packing member 110 can reliably close the gap between the container body 2 and the plug body 3 by simply mounting the plug body 3 from the upper side to the lower side with respect to the container body 2, thereby providing a stable water-stopping property. Can be secured.

  In addition, since the pair of release buttons 160 are arranged along the width direction X, the portable beverage container 1 simply holds the pair of release buttons 160 when the user holds the plug 3. The user can easily press the pair of release buttons 160 substantially simultaneously.

  In addition, since the portion exposed to the outside through the outer plug opening 132a is configured as a semicircular portion having a substantially semicircular shape in plan view, the release button 160 can be placed inside the bag in a state of being stored in a bag, for example. The load when the stored item comes into contact can be received in a direction other than the inside of the width direction X by the curvature of the semicircular portion.

  Thereby, even if the release button 160 contacts the storage thing in a bag, it can suppress being pressed toward the inner side of the width direction X, for example. Therefore, since the portable beverage container 1 cannot be opened unless the release button 160 is intentionally pressed, unintentional opening can be more reliably prevented.

  Moreover, the part which protrudes outward from the plug 3 is substantially semicircular in a plan view, and the release button 160 having a metallic luster makes the portable beverage container 1 excellent in design. .

  Further, for example, when the plug 3 in a plan view has a diameter of 60 mm to 70 mm, when the release button 160 slides about 2 mm inward in the width direction X, the outer pressing portion 163 of the release button 160 and the locking member 140 are brought into contact with each other. With the configuration in contact, the portable beverage container 1 can have a play in the amount of slide movement of the release button 160.

  For this reason, the restricting member 170 can form the first groove portion 175a of the restricting groove 175 in a substantially oval shape in plan view. Thereby, when one release button 160 is pressed, the portable beverage container 1 has the protrusion 164 in the first groove portion 175a of the restriction groove 175, compared to the case where there is no play in the sliding movement amount of the release button 160. You can be sure to stay.
