  As described above, the lock mechanism of the lid provided in the beverage container is required to have both easy opening and closing operation of the lid and reliable locking when the lid is closed. However, if the opening / closing operation of the lid is facilitated, the certainty of locking when the lid is closed is likely to be impaired. On the other hand, if a reliable lock is to be performed, the lock operation takes time and labor, and convenience is impaired.

  It is an object of the present invention to provide a beverage container locking mechanism and a beverage container that can achieve both easy opening and closing operation of a lid and reliable locking.

One aspect of the present invention is a lock mechanism for a beverage container for locking and unlocking a lid body attached to the opening of a container body having an opening at the top, the hinge mechanism being attached to a peripheral position of the opening of the container body. An annular body for opening and closing the lid body via the operation body, and an operation portion provided on the side opposite to the hinge of the annular body.
The annular body is provided with a support portion that supports the operation portion and a stopper provided below the support portion.
The operating section has an engaging section that engages with the lid, and is swingably provided with respect to the supporting section, and vertically slidable with respect to the swinging section outside the swinging section. And a slide portion that is urged downward.
In such a lock mechanism for a beverage container, when the slide part is located at the lowest position in the slide range, the slide part contacts the stopper to prevent the swing part from swinging, and the slide part moves in the middle of the slide range. When it is located above the predetermined position, the slide portion is disengaged from the stopper, and the swing portion and the swing portion can swing.

  According to such a configuration, by sliding the sliding portion upward, the swinging portion can be swung apart from the stopper, and the swinging of the swinging portion causes the engagement between the lid body and the engaging portion. It is released and the lid can be opened. On the other hand, when no force is applied to the slide portion, the slide portion moves downward due to the urging force and abuts the stopper to prevent the swing portion from swinging. That is, when no force is applied to the slide portion, the swing state of the swing portion can be automatically shifted to the locked state.

  In the above lock mechanism for a beverage container, the stopper is provided in a convex shape protruding from the annular body, and when the slide portion slides downward by the urging force, the lower end portion of the slide portion is positioned so as to ride on the stopper, and slides. It may be provided so that the lower end portion of the sliding portion is disengaged from the stopper and can be pushed when the portion is slid upward against the biasing force. This makes it possible to switch between a locked state where the lower end portion of the slide portion rides on the stopper and an unlocked state where the lower end portion of the slide portion is disengaged from above the stopper by the vertical sliding movement of the slide portion. .

  In the beverage container lock mechanism, the swinging portion is positioned so that the engagement portion and the lid can be engaged by the ride of the lower end portion on the stopper, and the swinging portion is prevented from swinging. Alternatively, the lower end portion may be provided so as to be disengaged from above the stopper and pushed so that the swinging portion swings to release the engagement of the engaging portion with the lid. Accordingly, in the state where the engaging portion and the lid can be engaged with each other, the locked state can be realized by the lower end portion of the slide portion riding on the stopper. In addition, the unlocked state due to the lower end of the slide portion being disengaged from the stopper and the opening of the lid body due to the disengagement of the engagement portion and the auxiliary portion by the swinging of the swinging portion can be performed by one operation. It can be carried out.

  In the beverage container lock mechanism, the convex wall portion is formed by the support portion and the stopper, and when the lower end portion is disengaged from the stopper by sliding the slide portion upward, the lower end portion is pushed into the convex wall portion. It may be provided so that it may be located. With this, the lower end portion of the slide portion is pushed into the inside of the convex wall portion by one operation of sliding the slide portion upward, and the unlocked state and the release of the engagement between the engaging portion and the lid are naturally performed. Can be done.

  In the lock mechanism for a beverage container, a spring for applying an urging force to the slide portion is provided, and the engagement portion and the lid can be engaged in association with the operation of the slide portion sliding downward due to the urging force of the spring. It may be provided so that the swing of the swing portion is biased to the position. With this, it is possible to realize the downward biasing of the slide portion and the biasing of the swinging portion through the movement of the slide portion by one spring.

  One aspect of the present invention is a beverage container including a container body having an opening in an upper portion thereof, a lid body attached to the opening of the container body, and the above-described beverage container locking mechanism. With such a configuration, the beverage container lock mechanism described above achieves both ease of opening and closing the lid and reliable lock operation.

The beverage is stored in the container body 2 through the opening 2a. If the container body 2 has a vacuum heat insulating structure, the performance of keeping cold and keeping warm of the contained beverage can be improved.

  The lid 3 is attached to the opening 2 a of the container body 2 so as to be openable and closable. In this embodiment, the lid 3 is rotatably attached via the hinge 3a. The lid 3 is biased in the opening direction by a spring (not shown), and when a lock mechanism 1 described later is operated to open the lid 3, the lid 3 is automatically opened by the biasing force of the spring. .

  In the present embodiment, a state in which the lid 3 is closed (a state in which engaging portions 211 and 311 described later are engaged) is a closed state, and the lid 3 is in a closed state and is locked by the lock mechanism 1. The locked state (the state that prevents accidental opening) is the locked state, the closed state of the lid 3 that is not locked is the unlocked state, and the state that the lid 3 can be opened (engaged The state in which the parts 211 and 311 are not engaged) is referred to as an open state.

  A drinking spout 4 may be attached to the opening 2 a of the container body 2. It is preferable that the spout 4 is detachably attached to the opening 2a of the container body 2. When the lid 3 is closed, the spout 4 is sealed by the packing 3b provided on the back side of the lid 3.

  In the beverage container 100 according to this embodiment, the lid 3 can be changed from the locked state to the opened state by one operation (operation) by the lock mechanism 1. That is, the lid 3 in the locked state can be opened by a so-called one-touch operation. On the other hand, when closing the lid 3 that is open, it is possible to change the open state to the locked state by only closing the lid 3.

(Structure of lock mechanism for beverage container)
The lock mechanism 1 according to the present embodiment is provided with a ring-shaped body 10 that is attached to a position around the opening 2a of the container body 2 and that opens and closes the lid 3 via the hinge 3a, and the hinge 3a of the ring-shaped body 10 is opposite. And an operation unit 20 provided on the side.

  The ring-shaped body 10 is a ring-shaped member attached to a position around the opening 2 a of the container body 2. The annular body 10 is screwed to a position around the opening 2a of the container body 2 by a screw portion provided on the upper part of the container body 2, for example. The annular body 10 may be attached to the container body 2 by fitting other than screwing, or may be attached to the container body 2 via another member (attachment with an intermediate member interposed). ). Further, a part of the container body 2 may be used as the annular body 10 (the annular body 10 and the container body 2 are integrated). The annular body 10 is provided with a hinge 3a that serves as an axis for rotating the lid body 3. The annular body 10 is formed of, for example, resin.

  The operation unit 20 is provided on the opposite side of the annular body 10 from the hinge 3a. That is, the operation unit 20 is provided on the opening / closing side of the lid body 3 that rotates via the hinge 3 a, and includes a mechanism for opening / closing the lid body 3. A support portion 11 is provided on the side of the annular body 10 opposite to the hinge 3a. The operation unit 20 is attached to the support unit 11. The support portion 11 has a pair of wall members 11 a provided on the outer peripheral surface of the annular body 10. The pair of wall members 11a extend in the vertical direction, and the operation unit 20 is attached between the pair of wall members 11a.

  A stopper 12 is provided below the support portion 11. The stopper 12 is provided in a convex shape protruding outward from the outer peripheral surface of the annular body 10. In this embodiment, the pair of wall members 11 a of the support 11 and the stopper 12 form a substantially U-shaped convex wall portion. The pair of wall members 11a and the stopper 12 may be formed integrally with the annular body 10 or may be formed separately. Alternatively, the inner wall surfaces of the annular body 10 that face each other by the recess provided inside the outer peripheral surface of the annular body 10 may be configured as a pair of wall members 11 a, and the lower edge portion of the recess may be configured as the stopper 12.

The operation unit 20 includes a swing unit 21 and a slide unit 22. The rocking | swiveling part 21 is attached between a pair of wall members 11a via the pin 21a, and is rockable | fluctuated with respect to the support part 11 centering | focusing on the pin 21a. An engaging portion 211 that engages with the lid body 3 is provided above the swinging portion 21. The engaging portion 211 is provided, for example, in a claw shape extending inward. An engaging portion 311 is provided on the lid 3 side corresponding to the engaging portion 211. The engaging portion 311 is provided, for example, in a claw shape extending outward. Engagement of the engaging portion 211 of the rocking portion 21 with the engaging portion 311 of the lid 3 brings the lid 3 into a closed state. The engaging portions 211 and 311 may each have a claw shape, or one may have a claw shape and the other may have a hole shape.

The slide portion 22 is provided outside the swing portion 21 so as to be slidable in the up-down direction with respect to the swing portion 21. The slide portion 22 is provided so as to cover the outside of the swinging portion 21, and is attached between the pair of wall members 11a of the support portion 11 by the pin 21a. That is, the slide portion 22 and the swinging portion 21 is overlapped with the slide portion 22 outwardly, each other the swinging portion 21 as the inner, is mounted between the pair of wall members 11a through a common pin 21a.

  The hole 22a of the slide portion 22 into which the pin 21a is inserted is a long hole extending in the vertical direction, and the slide portion 22 supported by the pin 21a can slide in the vertical direction. The slide portion 22 is slidable along the outer surface of the swingable swinging portion 21. Therefore, the slide portion 22 swings with respect to the support portion 11 together with the swing portion 21, and can slide up and down along the outer surface of the swing portion 21.

  Further, the slide portion 22 is biased downward. In the present embodiment, the spring 23 is provided between the swing part 21 and the slide part 22. The spring 23 is incorporated inside the swinging part 21 and between the spring receiving part 212 of the swinging part 21 and the spring receiving part 222 of the slide part 22. Since the swinging part 21 does not move in the vertical direction, the slide part 22 is biased downward by the spring 23.

3A and 3B are schematic views illustrating the locked state. FIG. 3A shows a schematic cross-sectional view illustrating the locked state, and FIG. 3B shows a schematic perspective view from the inside of the operation unit 20.
FIGS. 4A and 4B are schematic views illustrating the open state. FIG. 4A shows a schematic cross-sectional view illustrating the open state, and FIG. 4B shows a schematic perspective view from the inside of the operation unit 20.

  In such a lock mechanism 1, as shown in FIG. 3A, when the slide portion 22 is located at the lowest position in the slide range, the lower end portion 221 of the slide portion 22 is in contact with the stopper 12. That is, since the slide portion 22 is pushed downward by the urging force of the spring 23, the lower end portion 221 of the slide portion 22 is positioned above (outside) the stopper 12. As a result, the lower end portion 221 of the slide portion 22 cannot be pushed inward, and the swinging portion 21 is prevented from swinging.

  On the other hand, as shown in FIG. 4A, when the slide portion 22 is located above a predetermined position on the way in the slide range, the lower end portion 221 of the slide portion 22 comes out of the stopper 12. That is, when the slide portion 22 is slid upward against the urging force of the spring 23, the lower end portion 221 of the lower end portion 221 of the slide portion 22 is disengaged from the position of the stopper 12, and the support portion 11 and the stopper 12 are formed. Is pushed into the inside (concave portion) of the convex wall portion. As a result, the swinging portion 21 swings, the engaging portion 211 on the upper side of the swinging portion 21 opens outward, and the engagement with the engaging portion 311 is released. As a result, the lid 3 is opened.

  After the lid 3 is opened, if the force applied to the slide portion 22 is weakened, the slide portion 22 slides downward due to the urging force of the spring 23, and the lower end portion 221 of the stopper 12 again moves. It will be located above and will return to the locked state. When the slide portion 22 is returned by the urging force of the spring 23, the lower surface of the lower end portion 221 of the pushed slide portion 22 contacts the upper side surface 12 a of the stopper 12. Since the upper side surface 12a is provided with an inclination (an inclination that decreases toward the outside), the lower end portion 221 can easily return to the position of the stopper 12. Therefore, the slide portion 22 can be slid downward by the urging force of one spring 23, and the lower end portion 221 of the slide portion 22 can be easily returned to the outside. The bias of can be realized.

(Opening operation)
Next, the opening operation of the lid body 3 by the lock mechanism 1 will be described.
5A to 5C are schematic perspective views illustrating the opening operation.
6A to 6C are schematic cross-sectional views illustrating the opening operation.
A locked state is shown in FIGS. 5 (a) and 6 (a). In the locked state, with the lid body 3 closed, the engagement portion 211 of the swing portion 21 and the engagement portion 311 of the lid body 3 are engaged, and the slide portion 22 of the operation portion 20 is attached by the spring 23. It is located at the bottom of the slide range due to power. In this position, the lower end portion 221 of the slide portion 22 rides on the stopper 12, and the swing portion 21 is prevented from swinging via the slide portion 22.

  Therefore, even if the slide portion 22 is pushed, the stopper 12 prevents the push-in, and the swinging portion 21 is also prevented from swinging. If the swinging part 21 cannot be swung, the engagement between the engaging part 211 of the swinging part 21 and the engaging part 311 of the lid 3 is not released, and the closed state can be maintained. That is, in the locked state, it is possible to prevent the sliding portion 22 from being pushed and prevent the lid 3 from being opened accidentally.

  An unlocked state is shown in FIGS. 5 (b) and 6 (b). When the slide portion 22 is slid upward from the locked state and is located above a predetermined position on the way in the slide range, the lower end portion 221 of the slide portion 22 comes out of the position of the stopper 12. In this state, since the lower end portion 221 of the slide portion 22 does not contact the stopper 12, it is possible to push the lower end portion 221 of the slide portion 22 inward.

  In addition, unless the lower end portion 221 of the slide portion 22 is pushed in the unlocked state, the engagement between the engaging portion 211 of the swinging portion 21 and the engaging portion 311 of the lid 3 is not released. Further, if the upward force applied to the slide portion 22 is weakened without releasing this engagement, the slide portion 22 slides downward due to the urging force of the spring 23, and the lower end portion 221 again causes the stopper 12 to move upward. It will be located at and will return to the locked state.

  The open state is shown in FIGS. 5 (c) and 6 (c). When the lower end portion 221 of the slide portion 22 is pushed in from the unlocked state, the swing portion 21 swings through the pushing operation of the slide portion 22. That is, the pin 21a swings so that the side (upper side of the pin 21a) opposite to the side (lower side than the pin 21a) pushed by the slide portion 22 of the swinging part 21 opens outward. As a result, the engagement between the engaging portion 211 of the swinging portion 21 and the engaging portion 311 of the lid 3 is released, and the lid 3 is opened. In the open state, the lid 3 is opened by the urging force of a spring (not shown) that urges the lid 3 in the opening direction.

  In the lock mechanism 1 according to the present embodiment, when the slide portion 22 of the operation portion 20 is slid upward and the lower end portion 221 is disengaged from the position of the stopper 12, the lower end portion 221 of the slide portion 22 is naturally pushed and shakes. The lid 3 can be opened by swinging the moving part 21. In other words, by sliding the slide portion 22 in the upward direction, the slide portion 22 is naturally pushed in at a stage beyond the position of the stopper 12 without being aware of the pushing operation. It becomes possible to shift to.

(Close operation)
Next, the closing operation of the lid 3 by the lock mechanism 1 will be described.
7A to 7C are schematic cross-sectional views illustrating the closing operation.
FIG. 7A shows a state before closing the lid 3. In the opened state of the lid body 3, when no force is applied to the slide portion 22 of the operation portion 20, the slide portion 22 is returned to the lowest position in the slide range by the biasing force of the spring 23. At this position, the lower end portion 221 of the slide portion 22 rides on the stopper 12, and the engagement portion 211 on the upper side of the swing portion 21 is in a closed state.

  FIG. 7B shows a state in which the lid 3 is closed and the engaging portion 211 and the engaging portion 311 are in contact with each other. In the state where the slide portion 22 is returned to the lowest position in the slide range, the engaging portion 211 of the swinging portion 21 is inwardly closed. Therefore, when the lid body 3 is closed, the lid body 3 is closed. The engaging portion 311 of and the engaging portion 211 of the swinging portion 21 come into contact with each other. When the lid body 3 is pressed from above in this state, the lid body 3 is closed while the engaging portion 311 of the lid body 3 pushes the engaging portion 211 of the swinging portion 21.

  Then, when the engaging portion 311 of the lid body 3 moves over the position of the engaging portion 211 of the swinging portion 21, as shown in FIG. 7C, the engaging portion 311 of the lid body 3 and the swinging portion 21 are separated. The engaging portion 211 is engaged and the closed state is established. That is, as shown in FIGS. 7A to 7C, when the operation of closing the lid body 3 is continued, the lid body 3 starts to close, and the engaging portion 311 of the lid body 3 and the engaging portion of the swinging portion 21. A reaction force is generated in the force that closes the lid body 3 at the position where the lid 311 abuts. When the lid body 3 is further pressed from there, the engaging portion 311 of the lid body 3 feels some resistance when pushing the engaging portion 211 of the swinging portion 21, and eventually the engaging portion 311 of the lid body 3 is detected. It can be seen that when the vehicle crosses over the engaging portion 211 of the swinging portion 21, a click feeling is obtained and the closed state is achieved. The reaction force and click feeling when pressing the lid 3 is set by the angle of the contact surfaces of the engaging portion 211 and the engaging portion 311.

  As shown in FIG. 7C, when the lid 3 is closed to be in the closed state, the slide portion 22 remains at the lowermost position in the slide range, so that the slide portion 22 is brought into the closed state and the lock state at the same time. .

(Other examples)
Next, another example of the lock mechanism 1 according to the present embodiment will be described.
FIG. 8 is a schematic cross-sectional view showing another example.
In the lock mechanism 1 shown in FIG. 8, a gap D is provided between the upper portion of the slide portion 22 and the swing portion 21. A spring 24 is provided between the lower part of the swing part 21 and the annular body 10 so as to bias the lower part of the swing part 21 to the outside. The spring 24 is provided so as to expand and contract inward and outward, and has one end abutting the annular body 10 and the other end abutting the spring receiving portion 212 of the swinging portion 21.

  In the lock mechanism 1 as described above, the biasing force of the spring always applies a force to the engaging portion 211 provided on the upper portion of the swinging portion 21 in the inward closing direction. When the lid 3 is closed, the engaging portion 311 of the lid 3 comes into contact with the engaging portion 211 of the swing portion 21, so that a force is applied to the outside of the engaging portion 211. At this time, since the gap D is provided between the swing part 21 and the slide part 22, the swing part 21 is slightly expanded outward against the biasing force of the spring. Therefore, the reaction force at the time of closing the lid body 3 becomes weaker than in the case where the gap D is not provided, and the lid body 3 can be closed with a light force to be in the locked state.

(Example of use)
Next, a usage example will be described.
9A and 9B are schematic perspective views showing a usage example.
9A shows a state in which the slide portion 22 is slid by the thumb S, and FIG. 9B shows a state in which the slide portion 22 is pushed in by the thumb S.
As shown in FIG. 9A, the container body 2 is held by one hand, and the thumb S is placed on the slide portion 22. Then, the slide portion 22 is slid upward with the thumb S. At this time, from the thumb S to the slide portion 22, a force for sliding the slide portion 22 in the upward direction (upward force) and a part of the force for grasping the container body 2 (inward direction force) are included. Is added. When the lower end portion 221 of the slide portion 22 is located on the stopper 12, the inward force is received by the stopper 12, so that only the upward force is applied to the slide portion 22 and the slide portion 22 moves upward. Will slide to.

  When the slide portion 22 slides upward and the lower end portion 221 moves out of the position of the stopper 12, an inward force applied from the thumb S to the slide portion 22 acts, and the lower end portion 221 of the slide portion 22 moves inward. Pushed in. This force in the inward direction is applied to the thumb S for gripping the container body 2, so that the force is naturally applied without paying attention to the force for pushing. As a result, the lower side (lower side than the pin 21a) of the swinging portion 21 inside the slide portion 22 is pushed in interlocking with the pushing operation of the lower end portion 221 of the slide portion 22, and the opposite side with the pin 21a as the center. Swing so that the upper side opens outward. When the upper side of the swinging part 21 is opened outward, the engagement between the engaging part 211 of the swinging part 21 and the engaging part 311 of the lid 3 is released, and the lid 3 is opened.

  The sliding operation of the slide portion 22 by the thumb S and the pushing operation when the position of the stopper 12 is exceeded are continuously performed without distinguishing them. Further, the slide portion 22 is a member for setting the lock state and also a member for setting the open state. Therefore, when the lid 3 is opened, (1) the operation of changing from the locked state to the unlocked state and (2) the operation of changing from the unlocked state to the opened state are interrupted by the operation of one member (slide portion 22). The operation can be continuously performed without any operation, and it is possible to shift from the locked state to the opened state with a so-called one-touch operation. Further, in the lock mechanism 1 according to the present embodiment, when the lid body 3 is opened, the opening direction of the lid body 3 and the sliding direction (upward direction) of the slide portion 22 are coincident with each other, so that the lid body can be held with the thumb S. It is possible to open the lid 3 by a natural motion by moving the lid 3 to open.

  As described above, according to the present embodiment, it is possible to provide the lock mechanism 1 and the beverage container 100 that can achieve both easy opening / closing operation of the lid 3 and reliable locking. .

  Although the present embodiment and its application examples have been described above, the present invention is not limited to these examples. Further, with respect to each of the above-described embodiments or application examples thereof, those skilled in the art appropriately added, deleted, and modified the components, and those obtained by appropriately combining the features of the respective embodiments are also included in the present invention.
