Description

[Detailed Description of the Invention] The present invention relates to a manual air pot, and more specifically, the presser cover that presses and drives the air pump is rotated to engage and disengage the presser cover from the upper cover. At the same time, the bottle outer tube for guiding the liquid inside the bottle to the outside is composed of a fixed tube section and a movable tube section, and the movable tube section is connected to the outer peripheral surface of the pot body. This invention relates to an improvement to an air pot that can appear and appear at will.

Conventionally, in this type of air pot, in order to make the movable tube part of the bottle outer tube protrude and retract from the outer peripheral surface of the pot body, the movable tube part has to be manually operated.

In this case, manual operation is required each time the movable tube section moves in and out, which is extremely troublesome.

In addition, since the retracting and retracting operations of the movable tube section and the locking operations of the presser foot cover can be performed independently, there is no possibility of accidentally pressing the presser foot cover while the movable tube section is retracted. There is a problem in that the liquid inside the bottle is poured out and leaked to the outside.

The present invention was devised in view of the above-mentioned problems, and the presser cover and the movable tube are linked together via a locking rod and a rotation plate that rotate together with the presser cover, and the presser cover is locked only when the presser cover is locked. Strain once so that the movable tube part can protrude outside the outer peripheral surface of the pot body.
Therefore, the purpose is to solve the above problems all at once.

Hereinafter, an air pot according to an embodiment of the present invention will be described with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 denotes the air pot body, 2 the middle bottle, 3 the lower mouth member, 4 the upper lid which is pivotally connected to the lower mouth member 3 via a hinge pin 5 so that it can be opened and closed freely, and 6 the bellows. 7 is an inner stopper that is tightly fitted into the stopper insertion hole 8 of the lower mouth member 3, and 9 and 10 are an inner pipe and an outer pipe for leading out the liquid inside the inner bottle 2 to the outside. The pipe 11 is a presser lid for pressing and driving the air pump 6.

The bottle outer tube 10 is fitted into a fixed tube section 14 integrally formed with the descending member 3 and the outer periphery of the fixed tube section 14 so as to be able to move forward and backward, and is always urged in the retraction direction (that is, the direction of arrow A) by a spring 26. It consists of a movable tube section 15.

This outer bottle tube 10 is connected to the bottle inner tube 9 via a connecting tube section 27 connected to the inner end of the fixed tube section 14, and the bottle liquid flows through the bottle inner tube 9 and the bottle outer tube 10. The liquid is poured out through the distal end spout 28 of the movable pipe portion 15 to the outside.

The movable pipe portion 15 is recessed into the outer circumferential surface of the pot body 1 under normal conditions, and only when the liquid in the bottle is poured out, the movable pipe portion 15 is recessed into the outer circumferential surface of the pot body 1.
As shown, it is made to protrude outside the outer peripheral surface of the pot body 1.

Furthermore, claw pieces 24 are integrally provided at appropriate locations on the upper surface of the movable tube portion 15 .

On the other hand, a presser lid 11 is inserted into a hole 16 formed in the upper surface of the upper lid 4 so as to be movable up and down.

An L-shaped protrusion 18 is formed on the peripheral wall 17 of the holding lid 11, while the protrusion 18 is formed on the peripheral wall 19 of the hole 16 in the upper lid 4.
A stopper 20 is provided protrudingly to engage with the horizontal portion 18a of 8 to restrict the vertical movement of the presser cover 11 (see Fig. 2).
.

When the stopper 20 is engaged with the horizontal part 18a of the protrusion 18, the presser cover 11 is locked, and when the stopper 20 comes off the lower end of the vertical part 18b of the protrusion 18, the presser cover 11 is locked.
1 is now unlocked.

Further, a guide groove 21 is formed in the peripheral wall 17 of the presser lid 11 in the vertical direction.

One end 12a of an L-shaped locking rod 12 disposed inside the upper lid 4 is inserted into the guide groove 21, and the locking rod 12 also rotates as the presser lid 11 rotates. It has become.

The other end 12b of the locking rod 12 engages with a rotating plate 13, which will be described later.

The rotary plate 13 has a donut-like shape as shown in FIG.
3, 23, 23 and one cam surface 22 are formed.

This rotating plate 13 is arranged on the lower surface of the air pump bottom plate 25 so as to rotate concentrically with the presser cover 11.

A flange portion 30 is formed on the outer peripheral edge of the air pump bottom plate 25 via a step portion 29, and appropriate sliding grooves 31, 31, and 31 are formed in the step portion 29.

Then, the locking arm rods 23, 23.23 of the rotating plate 13 are respectively inserted into the sliding grooves 31.
The rotating plate 13 is rotatably attached to the air pump bottom plate 25 by contacting the upper surface thereof.

One of the locking arm rods 23, 23.23 and the locking rod 12
By engaging the lower end portion 12b of the cam surface 22 and the claw piece 24 of the movable tube portion 15, the presser lid 11 and the movable tube portion 15 are linked,
It's wet.

When the locking rod 12 and the rotating plate 13 are rotated by rotating the presser cover 11, the claw piece 24 is guided by the cam surface 22 and moves, and the movable tube part 15 moves along the pot body 1. It is designed to protrude and retract from the outer circumferential surface of 7.

Note that the reference numeral 32 is a groove formed in the lower mouth member 3 for guiding the claw piece 24.

Next, the action of the illustrated air pot will be explained.

In the case shown by the solid line in FIG. 2, the presser cover 11 is locked and the movable tube portion 15 is in the retracted state.

That is, the stopper 20 on the upper lid 4 side engages with the horizontal portion 18a of the protrusion 18 of the presser lid peripheral wall 17 to lock the presser lid 11 so that it cannot move up and down, while the claw piece 24 of the movable tube portion 15 engages with the horizontal portion 18a of the protrusion 18 of the presser lid peripheral wall 17. The movable tube portion 15 is placed at the inner end of the cam surface 22 of the movable tube portion 15 in a retracted state.

In this system, since the presser cover 11 cannot be pressed, there is no possibility of accidentally pouring out the liquid in the bottle while the movable pipe section 15 remains in the retracted state.

When trying to pour out the liquid in the bottle using this air pot, when the presser lid 11 is rotated in the direction of arrow C, the stopper 20 comes off from the horizontal part 18a of the protrusion 18, and the presser lid 11 is moved up and down. At the same time that the lock is movably released, the locking rod 12 and the rotating plate 13 similarly rotate in the direction of arrow C,
The claw piece 24 of the movable tube portion 15 is guided by the cam surface 22 and moves in the direction of arrow B, as shown by the chain line in FIG.

Accordingly, the movable tube portion 15 is also pushed out in the direction of arrow B against the biasing force of the spring 26, and as shown in FIGS.
As shown by 5', it protrudes outside the outer peripheral surface of the pot body 1.

Under this system, when the presser cover 11 is pressed, the air pump 6 is driven and pressurized air can be pumped into the medium bottle 2, and the pressurized air transfers the liquid inside the bottle to the bottle inner pipe 9. And it can be poured out through the bottle outer tube 10.

Thereafter, when the presser cover 11 is released, the movable tube section 15 returns to the retracted state due to the urging force of the spunong 26, and at the same time, the rotating plate 13, the locking rod 12, and the presser cover 11 rotate in the opposite direction. The presser lid 11 is then locked.

In the illustrated embodiment, the return spring 26 is provided on the movable tube portion 15 side, but the return spring 26 may be provided on the presser cover side, or even no return spring may be provided at all. Good too.

In these cases, the retracting operation of the movable tube section 15 must be performed manually.

Further, in the illustrated embodiment, the fixed tube portion 1 of the bottle outer tube 10 is
4 is formed integrally with the lower mouth member 3, but the fixed tube portion 1
4 can also be attached to the inner stopper 7.

Next, the effects of the air pot of the present invention will be described.

. 1. . That is, according to the present invention, the presser cover 11 which presses and drives the air pump 6 and whose operation is locked or unlocked by its own rotational operation and the movable tube from which the bottle outer tube 10 can freely come out and retract. 15 through a locking rod 12 that rotates together with the presser cover 11 and a rotating plate 13 that engages with the lower end of the locking rod 12 and rotates concentrically with the presser cover 11, When the presser lid 11 is unlocked, the movable tube portion 15 can be made to protrude outside the outer circumferential surface of the pot body 1, so that the lock release operation of the presser lid 11 and the movable tube can be performed by simply rotating the presser lid 11. This makes the operation extremely easy, and prevents the liquid in the bottle from being accidentally poured out due to a conflict between the unlocking operation of the presser cover 11 and the operation of protruding the movable tube section 15. This has the practical effect of eliminating the fear of it being lost and allowing both operations to be reliably linked.
