Description

[Detailed Description of the Invention] The present invention relates to a safety device for a manual air pot, and more specifically, the present invention relates to a safety device for a manual air pot, and more specifically, the outer tube for guiding the liquid inside the bottle to the outside is connected to a fixed tube section and a fixed tube section relative to the fixed tube section. The present invention relates to a safety device for a manual air pot, which is configured with a movable tube section that is movable and can be moved in and out of the outer peripheral surface of the pot body.

In conventional air pots of this type, the presser cover that presses and drives the air pump and the movable tube portion of the outer tube are structurally independent.

Therefore, a safety device for locking or unlocking the operation of the presser cover is also configured independently of the operation of protruding and retracting the movable tube section.

Therefore, when pouring out the liquid in the bottle, it is necessary to perform the unlocking operation of the presser lid and the operation of protruding the movable tube separately, which is not only extremely troublesome but also requires the movable tube to be retracted. There is a problem in that there is a risk that the presser lid may be pressed by mistake and the liquid in the bottle may be inadvertently poured out.

The present invention links the presser cover that suppresses and drives the air pump with the movable tube section of the outer tube, and can unlock or lock the presser cover in accordance with the movement of the movable tube section. The purpose of this is to reduce the number of parts and prevent erroneous button operations when dispensing liquid in the bottle.

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

1 and 2, reference numeral 1 indicates the air pot body, 2 indicates the middle bottle, 3 indicates the lower mouth member, and 4 pivots to the lower mouth member 3 via a threaded pin 5 so that it can be opened and closed. The upper lid is attached, 6 is a bellows type air pump, 7 is the plug insertion hole 8 of the lower mouth member 3
The inner stopper 9 and 10 are an inner tube and an outer tube for leading the liquid inside the inner bottle 2 to the outside, and 11 is a presser lid for driving the air pump 6 to suppress it.

The outer bottle tube 10 is composed of a fixed tube section 13 connected to the inner stopper 7 and a movable tube section 14 fitted into the fixed tube section 13 so as to be movable forward and backward so as to be displaced relative to the fixed tube section 13.

A spout 16 is formed at the tip of the movable tube portion 14 .

Thus, when the movable tube section 14 is pulled out, it is projected outside the pot body 1 and the spout 16 is opened, whereas when it is pushed in, it is recessed into the outer peripheral surface of the pot body 1 and the spout 16 is opened. It is becoming blocked.

Further, the movable tube portion 14 is integrally provided with an engaging member 15 facing into the upper lid 4.

On the other hand, a locking member 12 is integrally provided on the presser lid 11 and extends downward to engage with the engaging member 15 .

By locking this locking member 12 to the engaging member 15 only when the movable tube portion 14 is retracted, the operation of the presser cover 11 is locked.

In the illustrated embodiment, the top lid 4 is connected to the pot body 1.
Although the pot body 1 can be opened and closed freely, it can be attached to and detached from the pot body 1 instead.

Further, the movable tube portion 14 of the outer bottle tube 10 may be rotated in an arc relative to the fixed tube portion 13.

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

FIG. 1 shows a case where the movable tube section 14 of the bottle outer tube 10 is in the retracted state and the presser lid 11 is in the locked state.

That is, the locking member 12 of the presser lid 11 is engaged with the engaging member 15 of the movable tube portion 14, thereby locking the presser lid 11.

In this system, the presser lid 11 cannot be pressed down, so there is no chance of inadvertently pouring out the liquid in the bottle while the movable pipe section 14 remains in the retracted state.

When trying to pour out the liquid in the bottle using this air pot, pull out the movable tube part 14 outside the pot body 1 and
The spout 16 is opened in the state shown in the figure.

Then, the engaging member 15 is disengaged from the locking member 12 of the presser cover 11, and the presser cover 11 is unlocked and can be operated for suppression.

Under this system, when the presser lid 11 is pressed down as shown by the chain line, the air pump 6 is driven and pressurized air is fed into the medium bottle 2, and the pressurized air moves the liquid inside the bottle. The liquid can be poured out from the spout 16 through the tube 9A and the bottle outer tube 10.

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

That is, according to the present invention, (1) The locking member 12 is integrally extended downward to the presser cover 11 that suppresses and drives the air pump 6, while the locking member 12 is retracted into the movable tube portion 14 of the outer bottle tube 10. The engaging member 15 that locks the locking member 12 only when the button is pressed is integrally provided, and the presser cover 11 can be operated or disabled by moving the movable tube section 14 in and out, thereby eliminating the need for a complicated locking mechanism. (2) When the movable tube section 14 is in the retracted state, the presser cover 11
Since the liquid in the bottle cannot be suppressed, the liquid in the bottle will not be inadvertently poured out, and an extremely safe safety device can be provided. It has practical effects such as being able to check whether a lock is present or not, making it much easier to use.
