Description

[Detailed Description of the Invention] This invention relates to a top opening lid locking device for pots and the like.

An opening lid is provided at the upper end of the pot where the liquid supply port is opened, and the device for locking the opening lid in the closed state is a so-called air pot that has a pump for dispensing the liquid content, or other types that do not have a pump. Various types are known. In many cases, the opening lid is locked in the closed state by keeping the stopper attached to the liquid supply port closed when not in use, and in the case of air pots, a bellows pump installed inside the lid and a stopper attached to the liquid supply port are used. In order to improve the handling and functionality of the pot, it is possible to maintain the connection between the stopper and the air supply passage to enable dispensing of the contents by pump operation, and to maintain the stopper attached to the liquid supply port. It is concerned with safety.

However, in the conventional opening lid locking device, as shown in the air pot shown in FIG. The part E is disengaged from the locking part F to release the lock of the lid A to the closed state, and such an operating part B
A simple operation force for the lid A is likely to act as an external force when a child plays a trick or the container G falls over, and the lock on the lid A may be inadvertently released, impairing the handling and functional safety. Ru. Further, after unlocking the lid A, it was difficult to open the lid A while pressing the operating portion B. Unexamined Japanese Patent Application Publication No. 1973 (1973)
The one described in the -66052 publication is known. This device has a vertical movement operation part on the front part of the opening lid, and when it is moved down, the locking member is locked in the engagement position with the locking part on the shoulder side, and this locking must be released. The lock member cannot be disengaged from the locking portion, so that the lid cannot be opened. Therefore, the opening lid can be unlocked only by the upward movement of the vertical movement operation part, and such an operation is difficult to be carried out mischievously or carelessly, thus solving the above-mentioned problem.

However, with this device, even if the locking member is given a backward movement behavior to the engaged position, the vertical movement operation section does not have a downward movement ability, and the above-mentioned safety is ensured unless the vertical movement operation section is moved downward after the lid is closed. Those that do not have the functionality,
When the vertical movement operation part, which does not have a downward movement behavior, is moved downward after closing the lid, the locking member moves to the engagement position and is locked in that position, locking the lid and locking it in the locked state. Therefore, there is an inconvenience in that the vertical movement operation section must be operated downward after the lid is closed. Also, if you forget to do this, there will be problems such as not being able to use the safety and lock functions.

If we try to solve this problem simply by giving the vertical movement operation section a reciprocating behavior, the locking member will be automatically locked in the engagement position with the shoulder side locking section, and in this state, When the lid is closed, the locking member collides with the immovable locking member and cannot be engaged with it, of course, resulting in damage.

Such a situation is unavoidable and a problem if the vertical movement operation section is erroneously moved downward before the lid is closed.

The purpose of this invention is to provide a top-opening lid locking device for pots that can solve such problems. An upper-end opening lid lock for pots, which has an opening lid that can be opened and closed freely, and a locking member that engages with a shoulder-side locking part at the front of the opening lid to lock the opening lid in the closed state. In the device,
A vertical movement operation part protruding from a part of the front surface of the opening lid so as to be able to move up and down is provided so as to provide a downward return movement, and this vertical movement operation part and the locking member are connected when the vertical movement operation part moves back. interlocking so that the locking member is in an engagement position with the locking portion on the shoulder side, and the locking member is in a disengagement position with the locking portion on the shoulder side when the vertical movement operation unit is moved upward; The interlocking section is provided with an interlocking safety means that enables the lock member side to move to the disengagement position by moving the vertically moving operating section upward or by playing with the vertically moving operating section. It is something to do.

This invention has such a configuration, and the vertical movement operation section is operated upward against the tendency of downward movement.
The locking member is released from the engagement position with the locking part, and at the same time, the locking member is moved up and down in conjunction with the upward movement of the vertical movement operation unit to disengage the locking part and release the lock of the open lid. In this state, the lid can be opened.

When the vertical movement operation part is released, such as after opening the lid, it automatically moves downward due to the downward movement behavior. At this time, the locking member is automatically moved back to the engagement position with the shoulder-side locking part in conjunction with the downward movement of the vertical movement operation part. When the lid is closed in this state, the locking member contacts the locking part, but due to the interlocking safety means between the vertical movement operation part and the vertical movement operation part, there is no play between the lock member and the vertical movement operation part. Since it can be moved to the disengaged position with the locking part with some movement, it is pushed and retracted to the disengaged position while it comes into contact with the locking part, making it possible to close the lid without damaging itself. can do.

When the lid has been closed, the locking member has gone over the locking part and is no longer pushed by the locking part, so it returns to the engagement position with the locking part and engages with the locking part, allowing the lid to open. can be automatically locked in the closed state.

This locked state can be achieved safely by simply opening and closing the lid without any special operations after opening the lid, without damaging any parts.Furthermore, after locking, the locked state is ensured by the downward movement of the vertical movement operation part. is maintained.

To explain the embodiment shown in FIGS. 2 to 4, reference numeral 1 is a container body, which has a vacuum double bottle 3 built in an outer case 2, and a bottle 3 at the upper end of the outer case 2. A dish-shaped shoulder member 5 having a liquid supply port 4 communicating with the tank is fixedly mounted. An openable lid 7 containing a manual bellows pump 6 is provided on the shoulder member 5 in a size and shape that covers the shoulder member 5. The opening lid 7 is pivoted to the rear of the shoulder member 5 by a shaft 8 and can be opened and closed, and has a pump press plate 9 at the center of the top plate and a lock lever at the front that engages with a locking portion 10 on the shoulder member 5 side. 11, and a vertical movement operating member 12 for operating the lever 11. A stopper 13 is detachably attached to the liquid supply port 4, and communicates with the discharge port 6a of the pump 6 to direct pressurized air from the pump 6 into the bottle 3 when the open lid 7 is in the closed state. and a pouring passage 15 that guides the liquid inside the bottle 3, which is pressurized by the air supplied from the pump 6 and is about to be pushed out, out of the container body 1.

The locking part 10 is provided to protrude from the inner surface of both side walls of the beak-shaped part 5a which is protruded from the front part of the shoulder member 5.
It is provided at the tip of an overhanging portion 15b that extends to one side of the upper end of the vessel body 1 through between the respective locking portions 10, and protrudes downward from the bottom opening 16 at the tip of the beak-shaped portion 5a.

The lock lever 11 opens the middle part and connects the shaft 19 to the bearing piece 18 integrally molded on the back plate 17 of the lid 7.
A hook portion 11a that engages with the locking portion 10 is formed at the tip of the back plate 17 facing downward from the window 20.
1a is always biased so as to maintain the unlocked state in which it is disengaged from the locking portion 10. On the other hand, the vertically movable operating member 12 is held movably up and down on the back side of the front part of the opening lid 7, and causes the operating part 12a to protrude from the window 22 toward the front surface of the opening lid 7 so as to be movable up and down. The above-mentioned vertically movable holding is achieved by opening the upper end of the member 12 and inserting it into the downward guide hole 7a in the lid 7, and by opening the protrusions 12b on both sides of the member 12 and inserting the guide grooves carved into the inner surfaces of the left and right guide walls 7b of the lid 7. 7c.

A spring 23 that biases the vertical movement operating member 12 downward acts, and this bias pushes the upper tail end 11b of the lock lever 11, so that the hook portion 11a of the lever 11 moves toward the locking portion 10. A pushing ramp 12c is provided to maintain the locked state against the spring 21 in engagement with the spring 21. Therefore, the force exerted by the spring 23 to keep the lever 11 in the locked state via the slope 12c is
The biasing force that keeps the lock lever 11 in the unlocked state is greater than the upward movement force exerted on the vertical movement operating member 12 via the slope 12c, and the degree of force is such that even if some impact or vibration is applied to the device body 1, the lock lever 11 It shall be sufficient to stably maintain the lock state. 1
Reference numeral 2d denotes a lever receiving piece that is vertically installed at the lower end of the slope 12c of the member 12, and serves to regulate the unlocked state position of the lever 11 and prevent the lever tail end 11b from falling off the slope 12c.

In addition, 24 in the figure is a normally closed valve provided in the middle of the stopper 13 of the pouring passage 15, and when the pump is operated by pressing down the press plate 9, the spring 25 and the operating rod 26
is pushed open downwardly through the passageway 15, allowing the liquid content to flow out through the passageway 15 by pump operation. 6b is an air supply port of the pump 6, and 27 is an intake port valve.

In the locked state shown in the figure, the connection between the discharge port 6a of the pump 6 and the air supply passage 14 of the stopper 13 via the packing 28 is maintained, and as long as the pump 6 is pushed, the pressurized air is released. can be applied into the bottle 3 without leaking, and the content liquid can be reliably poured out.

When the operating portion 12a is pulled up from the solid line position in FIG. 3 to the imaginary line position against the spring 23, the member 12 moves upward, causing the slope 12c to retreat from the lever tail end 11b. As a result, the lever 11 is rotated counterclockwise under the bias of the spring 21 while causing the tail end 11b to follow the slope 12c, and the hook portion 11a is rotated counterclockwise while the tail end 11b follows the slope 12c.
Remove it from 0, and the virtual line becomes unlocked. In this state, the lid 7 can be opened by lifting the lid 7 using the shaft 8 as a fulcrum, but this opening operation can be accomplished by lifting the operating portion 12a, which has been pulled up to unlock the lid 7, using the hook portion.
To release the lock and open the lid, for example, as shown in FIG. 3, by placing your thumb on the operation part 12a and placing your other four fingers on the top surface of the lid 7, you can balance the lid 7. Hold it well and lightly,
Pull up the operating part 12a as shown by arrow a to unlock the lid 7, then pull up the operating part 12a as shown by arrow b.
It can be easily performed continuously, such as by opening the lid using the hook as the hook. Moreover, during the operation and operation, the lid 7 can be held stably with only one hand, so there is no danger or worry that the container 1 will fall sideways, and there is no inconvenience or anxiety caused by the lid 7 slipping from the hand.

Once the lid 7 is opened, by removing the hand from the lid 7, the operating portion 12a is released. For this reason,
The vertical movement operating member 12 is moved downward by the force of the spring 23, and the spring 21 moves to the position shown by the solid line in FIG.
I am pushing back against it. Therefore, when returning the lid 7 from the open state to the closed state shown in the figure, the lock lever 11
The hook portion 11a comes into contact with the locking portion 10 and receives a force pushing it back to the position shown in the imaginary line in FIG. Due to the push-back force at this time and the biasing force of the spring 21,
The lever 11 moves upwardly against the spring 23 via the slope 12c and once moves to the third position.
The hook part 1 is in the unlocked position as shown by the imaginary line in the figure.
1a is released from the locking part 10. Then, when the lid 7 is tightly closed, the hook portion 11a overcomes the locking portion 10, and the pushing force of the locking portion 10 against the lever 11 is no longer exerted, so that the member 12 is biased by the spring 23. Twisted and moved downward;
The lever 11 is rotated through the slope 12c against the spring 21 to the solid line position in FIG. As described above, the opening lid 7 is automatically locked in the closed state by simply closing it, without requiring any other operation.

The closed state of the opening lid 7 can only be released by the upward movement of the vertically movable operating member 12, and is mostly caused by simply pushing down or pushing down, or by applying an external force, such as when a child plays a trick or when the container 1 falls sideways. Even if a force is applied to the operating portion 12a, the operation does not move the member 12 upward. Therefore, if the lid 7 is not locked in the closed state, air may leak even if the pump 6 is operated, making it impossible to pour out the liquid inside. There will be no inconvenience or danger such as the stopper 13 coming off from the liquid supply port 4 due to the locking of the lid 7 being released by an external action when it is tipped on its side, or a large amount of the liquid content flowing out. .

In FIG. 5, the auxiliary locking member 41 that locks the operating member 12 in the raised position is designed to automatically release the lock when the lid 7 is closed. For this purpose, the locking member 41 has a central portion pivotally attached to the front portion of the lock lever 11 by a shaft 42, and an upper end locking portion 41a.
is biased by a spring 43 so as to maintain the locked position below the operating member 12 in the raised position. At the final stage when the lid 7 is closed, the upper surface of the locking part 10 contacts the lower end passive part 41b of the locking member 41 and rotates the locking member 41 against the spring 43 to the unlocking position shown by the solid line. A guide slope 10a is formed to allow the movement.

When the operating member 12 is pulled up to the unlocked state shown by the imaginary line in the locked state shown by the solid line, the locking member 41 assumes the locked position shown by the phantom line due to the bias of the spring 43, and the member 41 is temporarily held in the locked state shown by the phantom line. Lock in the raised position. Therefore, the lock lever 11 is also in the unlocked position as shown by the imaginary line, and does not interfere with the closing of the lid 7 at all. At the final stage of closing the lid 7, the locking member 41 is rotated to the unlocking position shown by the solid line by the passive portion 41b of the locking member 41 coming into contact with the guide slope 10a of the locking portion 10, and the locking member 41 is no longer locked to the operating member 12. Since the lock lever 11 is released and moved downward, the lock lever 11 is automatically pushed back to the locked state shown by the solid line by the downward movement of the member 12, and the hook portion 11a is engaged with the locking portion 10 to lock the lid 7 in the closed state. . As described above, in this embodiment, it is not necessary to manually release the locking of the operating member 12 to the pulled-up position.

In FIG. 6, the tip hook portion 52a is engaged with the locking portion 10 by the biasing force of the spring 51, and the lid 7 is
A lock lever 52 is provided for locking the lock lever 52 in the closed state, and a tail end 52b of the lock lever 52 is engaged with the window 53 of the vertical movement operating member 12 with play,
Depending on the upward movement of the member 12, the lever 52 can be rotated clockwise to remove the hook portion 52a from the locking portion 10, whereas when closing the lid 7, the hook portion 52a
The operating member 12 in the downward movement position is allowed to rotate once to the imaginary line position in order to engage with the locking portion 10 by the play provided by the window 53. Therefore, there is no problem even if the operating member 12 is released and returns to the lowered position when the lid 7 is opened. Member 12
are the guide hole 7a of the lid 7 and the elongated hole 54 of the member 12.
The vertical movement is guided by the horizontal shaft 55 of the lid 7, which is inserted through the lid 7.

FIG. 7 shows a locking rod 61 held in an oblique position with its upper end tilted slightly backward toward the lid 7 so as to be able to move up and down.
The case of the simplest configuration in which the vertical movement operation section 62 is provided integrally is shown. The locking rod 61 is biased downward by the spring 63, and the lower end engaging portion 61a engages with the locking portion 1.
0 as shown in the figure, and the locking part 10 is not caught against the movement of the engaging part 61a which shows a trajectory as shown by arrow C when the lid 7 is opened, and the lid 7 is opened. Lock in closed position. When the locking lever 61 is pulled up to the imaginary line position, the engaging portion 61a is disengaged from the locking portion 10, and the lid 7 is placed in an unlocked state.
In this state, the lid 7 is opened, and the locking rod 61 is also released and returns to the lower position under the bias of the spring 63. However, when the lid 7 is closed again, the engaging portion 61a moves along the trajectory of the arrow C. When the lid 7 is completely closed, it comes off the guide slope 10b and engages with the locking part 10 as shown by the solid line in the figure. Then, lock the lid 7 in the closed state. Reference numeral 64 is a lock rod holding cylinder provided integrally with the back plate 17.

In the above embodiments, only the vacuum double-bottle type air pot is shown, but it goes without saying that the present invention can also be applied to heat-retaining pots, electric pots, etc. of various structures and types.

According to this invention, a vertically movable operation part protruding from a part of the front surface of the opening lid so as to be able to move up and down is provided so as to provide downward reciprocating behavior, and this vertical movement operation part and the locking member are connected to each other in a vertically movable manner. When the operation section moves backward, the lock member is in the engagement position with the locking part on the shoulder side, and when the vertical movement operation part moves upward, the locking member is in the disengagement position with the locking part on the shoulder side. This interlocking part is provided with an interlocking safety means that enables movement of the locking member side to the disengagement position by moving the vertical movement operation part upward or by play with the vertical movement operation part. Because of this, when the vertical movement operation part is released after opening the lid, it will automatically move downward due to the downward movement behavior, and at this time, the locking member will lock on the shoulder side in conjunction with the downward movement of the vertical movement operation part. automatically returns to the engagement position with the part. When the lid is closed in this state, the locking member contacts the locking part, but due to the interlocking safety means between the vertical movement operation part and the vertical movement operation part, there is no play between the lock member and the vertical movement operation part. Since it can be moved to the disengaged position with the locking part with some movement, it is pushed and retracted to the disengaged position while it comes into contact with the locking part, making it possible to close the lid without damaging itself. When the lid has been closed, the locking member has climbed over the locking part and is no longer pushed by the locking part, so it returns to the engagement position with the locking part, engages with the locking part, and opens. The lid can be automatically locked in the closed position.

Therefore, the locked state can be achieved safely by simply opening and closing the lid without any special operation after opening the lid, without damaging any parts, and it is convenient because no special operation is required to close the lid. There is no need to worry about forgetting to lock it in the correct position or to lock it. Furthermore, after locking, the locked state is firmly maintained due to the downward movement of the vertical movement operation part, which means that the lock can only be released by the upward movement operation, which further improves safety against tamper operations. .
