[0029]
The operation of the first embodiment will be described below.
When the lid 10 is closed from the opened state, the lower end portion of the locking portion 41 of the latch lock mechanism 40 becomes the inclined surface 41a, and the inclined surface 41a is formed in the lower mouth beak portion 8. With the inclined surface 7a at the upper edge of 7 (concave portion) as a guide surface, the locking portion 41 once moves the locking portion 41 (push button portion 42) in the contracting direction against the urging force of the spring 43. It is automatically locked by the locking receiving portion 7 (see FIGS. 1, 5, and 7).
[0030]
When the lid 10 is opened from the closed state, when the pair of push button portions 42, 42 of the latch lock mechanism 40 are pressed in the contracting direction against the urging force of the spring 43 by a human finger, Since the part 41 is unlocked from the latch receiving part 7, the lid 10 can be opened freely (see FIG. 7).
[0031]
When the latch lock mechanism 40 is in the locked state in the closed state, when the key 66, which is a key, is inserted into the lock 60, that is, the key hole 63 of the cylinder 62 and rotated in the locking direction, the lock rod 61 of the lock 60 is shown in FIG. As shown in FIG. 4 to FIG. 6 and FIG. 8, even if it is between the locking portions 41 and 41 of the latch lock mechanism 40 and pushes the push button portions 42 and 42 by hand, Since the locking part 41 comes into contact, the locking part 41 cannot be released from the locking receiving part 7 and the lid 10 cannot be opened without permission.
[0032]
In the case of unlocking from the locked state by the lock 60 and opening the lid, when the key 66 is inserted into the key hole 63 of the lock 60 (cylinder 62) and rotated in the unlocking direction, the lock rod 61 is shown by the chain line in FIG. As shown in FIG. 7, the push button portions 42 and 42 are separated from the lock portions 41 and 41, and the lock portion 41 and the lock receiving portion 7 of the push button portion 42 are unlocked as shown in FIG. Can be done without any problem. Therefore, when the lid 10 is opened from the closed state, as described above, when the push button portions 42, 42 are pressed by a human hand, the locking portion 41 is released from the locking receiving portion 7, and the lid 10 is released. Is freed up.
[0033]
Second Embodiment of the Invention
A second example of the embodiment of the present invention will be described below with reference to FIGS.
The second embodiment is common to the first embodiment in that the latch lock mechanism 40 and the lock 60 are provided in the lid-side beak portion 13. However, the lock 60 of the second embodiment has a slightly different configuration from that of the first embodiment. Since other configurations are the same as those of the first embodiment, the description of the first embodiment may be referred to for details.
[0034]
The lock 60 in this case is similar to the lock 60 of the first embodiment in that it has a cylinder 62 having a key hole 63 and a lock rod 61 connected to the tip of the cylinder 62. The lock rod 61 is characterized in that an arc-shaped notch 61a is formed on one end side.
[0035]
By having the notch 61a, when the latch lock mechanism 40 is in the locked state in the closed state, the cylinder 62 is operated in the locking direction (that is, the lock 66 is inserted into the key hole 63 and rotated in the locking direction). Thus, the outer peripheral edge portion of the notch portion 61a of the lock rod 61 comes close to or abuts on the shaft portion 41b of the locking portion. Therefore, even if the unauthorized unlocker compresses the push button portion 42 of the latch lock mechanism 40 in an attempt to unlock, the outer peripheral edge portion of the notch portion 61a remains on the push button portion 42 (the shaft portion 41b of the locking portion). Since the immersion is restricted, the locking portion 41 of the latch lock mechanism 40 cannot be released from the locking receiving portion 7 of the container body 1 and the lid 10 cannot be opened (FIGS. 11 and 11). 12, see virtual lines in FIG. At the time of locking, the notch 61 a of the lock rod 61 is formed so as not to hit the spring 43.
[0036]
In the case of unlocking from the locked state and opening the lid, when the key 66 is inserted into the key hole 63 of the cylinder 62 and rotated in the unlocking direction, the lock rod 61 is shown by a solid line in FIGS. 13, 14, and 15. As described above, the notch 61 a side of the lock rod 61 is rotated upward to disengage from the shaft portion 41 b of the latching portion of the latch lock mechanism 40, and the engagement between the latching portion 41 of the push button portion 42 and the container body 1. The engagement and disengagement with the stopper 7 can be performed without any trouble. Therefore, when the push button portions 42 are pressed by a human hand, the locking portion 41 is released from the locking receiving portion 7 and the lid 10 is released.
[0037]
Embodiment 3 of the Invention
A third example of the embodiment of the present invention will be described below with reference to FIGS.
The third embodiment is common to the first and second embodiments in that the latch lock mechanism 40 and the lock 60 are provided in the lid-side beak 13. However, the configuration and the mounting position of the lock 60 of the third embodiment are different from those of the first and second embodiments. Since other configurations are the same as those of the first embodiment, the description of the first embodiment may be referred to for details.
[0038]
The lock 60 in this case is fitted on the upper surface of the lid-side beak portion 13 at a position on the vertical line of the latch lock mechanism 40. That is, a mounting hole 15 for inserting the lock 60 is formed on a vertical line perpendicular to the latch lock mechanism 40 on the upper surface of the lid-side beak portion 13, and the guide tube 16 is dropped into the mounting hole 15. It is fitted in a shape. A cylinder 62 of a lock 60 which is a known cylinder lock is fitted to the guide cylinder 16 from above, and a lock rod 61 having a U-shaped cross section in FIG. 17 is connected to the bottom of the cylinder 62 from below. U-shaped notches 61b and 61b are formed in the lower portions of both side walls of the U-shaped lock rod 61, respectively, so that the lock rod 61 does not hit the spring 43 in the locked state.
[0039]
Similarly to the first and second embodiments, the latch lock mechanism 40 is fitted between the side walls of the lid-side beak portion 13 from the lateral direction.
[0040]
The cylinder 62 includes a spring (not shown), and the force of the spring causes the cylinder 62 to protrude upward as shown in FIGS. 17 and 18 even in the unlocked state and in the closed state. Therefore, the lock bowl 61 is also moving up. Therefore, the left and right push button portions 42 and 42 can be freely operated in the expansion / contraction direction, but by pushing the push button portions 42 and 42 in the compression direction, the engagement between the engagement portion 41 and the engagement receiving portion 7 is achieved. The lid 10 can be opened.
[0041]
As shown in FIG. 17, when the latch lock mechanism 40 is in the locked state in the closed state, the key 66 is inserted into the key hole 63 of the cylinder 62 and rotated in the locking direction. As shown in FIG. 20, the upper edge peripheral portions 61c, 61c of the notches 61b, 61b on both side walls of the lock rod 61 are fitted into the gap between the left and right push button portions 42, 42, and the upper edge peripheral portion 61c and 61c are contact | abutted by the axial part 41b of the latching | locking part of each pushbutton part 42 and 42. FIG. For this reason, the push button portions 42 and 42 cannot be pushed in the compression (immersion) direction, and the latch portion 41 of the latch lock mechanism 40 cannot be unlocked from the latch receiving portion 7 of the container body 1. The lid 10 cannot be opened.
[0042]
When unlocking from the locked state and opening the lid, when a key 66 is inserted into the key hole 63 of the cylinder 62 in the state shown in FIG. 19 and rotated in the unlocking direction, a spring (not shown) built in the cylinder 62 is shown. 17 and 18, the cylinder 62 and the lock rod 61 are moved upward, and the lower end portion of the lock rod 61 (the peripheral portion of the notch portion 61b) is engaged with the latch lock mechanism 40, as shown in FIGS. There is nothing that detaches from the gap 44 formed between the shaft portions 41b, 41b of the stop portion and prevents the push button portions 42, 42 of the latch lock mechanism 40 from expanding and contracting. As a result, when the push button portions 42 and 42 are pressed by a human hand, the locking portion 41 is released from the locking receiving portion 7 and the lid 10 is released.
[0043]
According to the liquid container lid locking device of the third embodiment, since the lock 60 is attached to the upper surface of the wide space of the lid-side beak portion 13, it is easy to assemble. Further, since the both push button portions 42, 42 employ a U-shaped lock rod 61, the left and right push button portions 42, 42 are locked to the U-shaped lock rod 61 at the time of locking. The left and right push button portions 42, 42 can be fixed evenly on the left and right sides, and the upper edge peripheral portions 61c, 61c of the notch portions 61b, 61b on both side walls of the lock rod 61 are spaced between the left and right push button portions 42, 42. Since the surface contact is made with respect to the shaft portion 41b of the locking portion that forms 44, there is an advantage that the left and right locking portions 41, 41 do not tilt.
[0044]
Embodiment 4 of the Invention
A fourth example of the embodiment of the present invention will be described below with reference to FIGS.
The fourth embodiment is different from the first to third embodiments in that the lock 60 is provided in the lower mouth part beak part 8 of the lower mouth part 4. Since other configurations are the same as those of the above-described embodiment, the description of each embodiment may be referred to for details.
[0045]
The lock 60 in this case is provided in the lower mouth part beak part 8 of the lower mouth part 4 of the container body 1 so as to face the latch lock mechanism 40 provided in the lid 10. That is, a mounting hole 9 for mounting the lock 60 is formed in the lower mouth beak portion 8 in the lateral direction. A cylinder 62 having a key hole 63 is fitted into the mounting hole 9, and a plate-shaped lock rod 61 is connected to the rear portion of the cylinder 62, and the lock rod 61 is connected to the inner space of the lower mouth beak portion 8.
