Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a siphon coffee extractor.

(Prior Art) A siphon-type coffee extractor has a lower container having a handle and an opening at the upper end, and a small-diameter pipe portion at the lower end portion, and a packing is fitted on the outer peripheral portion of the upper end of the pipe portion. It is composed of an upper container. When extracting the coffee liquid, first, a predetermined amount of water is stored in the lower container, and a predetermined amount of coffee powder is stored in the upper container. Then, the pipe portion of the upper container is inserted into the lower container, and the packing is press-fitted into the opening portion in an airtight state so that the upper container is mounted on the upper portion of the lower container. Next, the lower container is placed on the heater to heat the water inside. Then, the water in the lower container boils and the pressure in the lower container rises. When the pressure in the lower container rises above a predetermined pressure, the boiling water is introduced into the upper container through the pipe portion and mixed with the coffee powder to extract the coffee liquid. So when the heater is turned off,
The temperature of the lower container drops, the internal pressure drops, and the extracted coffee liquid in the upper container flows down into the lower container.
When all the coffee liquid in the upper container is stored in the lower container, the upper container is pulled up to release the packing part from the press-fitted state with the opening of the lower container, and the upper container is removed from the lower container. Then, holding the handle of the lower container, the coffee liquid inside is poured into and distributed in an appropriate container.

(Problems to be solved by the invention) In the above configuration, since the upper container is press-fitted in the opening of the lower container through the packing in an airtight state,
When removing the upper container from the lower container, it is necessary to pull up the upper container with a strong force, which is not easy to remove. Further, when the upper container is pulled up with a strong force to release the airtight state with respect to the lower container, the reaction causes the pipe part of the upper container to collide with the opening of the lower container and be damaged.

Therefore, an object of the present invention is to provide a coffee extractor which can easily remove the upper container from the lower container and can prevent the pipe portion of the upper container from being damaged.

[Means for Solving the Problem] (Means for Solving the Problems) A coffee extractor according to the present invention includes a lower container having a handle and an opening at an upper end, and a tube portion to be inserted into the lower container via a packing. An upper container removably attached to the opening in an airtight state, and the hot water boiled in the lower container is introduced into the upper container through the pipe section. It is characterized in that it is provided rotatably on the handle via a support shaft, and push-up means for pushing up the upper container and releasing the airtight state with respect to the lower container in accordance with the rotation.

(Operation) According to the coffee extractor of the present invention, when the push-up means provided on the handle of the lower container is rotated, the rotating push-up means pushes up the upper container to release the airtight state from the lower container. To be done. Therefore, if the upper container is pulled up, it can be easily removed from the lower container.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a lower container formed of, for example, heat-resistant glass in the shape of a flask, and an inclined opening 1a is formed in the upper portion thereof, the diameter of which gradually increases toward the upper side. 2 is the lower container 1
It is a handle attached to the small diameter part of the upper part by band tightening. Reference numeral 3 denotes an upper container made of, for example, heat-resistant glass, and a tube portion 4 having a diameter that becomes smaller toward the bottom of the upper container.
Is formed, and the packing 5 is fitted to the outer peripheral portion of the upper end of the tube portion 4. In use, the upper container 3 has its tube portion 4 inserted into the lower container 1 and the packing 5 is opened.
It is mounted on the upper part of the lower container 1 by pressing it into a in an airtight state.

Now, 6 is a lever having a U-shaped cross-section as a pushing-up means, which is arranged on the upper portion of the handle 2 so as to straddle the handle 2, and is supported by a support shaft 7 press-fitted on the upper portion of the handle 2 at a substantially central portion. . The lever 6 has a base end portion 6a which is pushed and is operated by an arrow A.
When rotated in the direction, the tip 6b comes into contact with the lower surface of the upper container 3.

Next, the operation of the above configuration will be described.

When extracting the coffee liquid, first, a predetermined amount of water is stored in the lower container 1, and a predetermined amount of coffee powder is stored in the upper container 3. Then, the tube portion 4 of the upper container 3 is inserted into the opening 1a of the lower container 1, the packing 5 is press-fitted into the opening 1a in an airtight state, and the upper container 3 is attached to the upper part of the lower container 1 ( (See FIG. 1). Next, the lower container 1 is placed on a heater (not shown) to heat the water inside.
Then, the water in the lower container 1 boils and the pressure in the lower container rises, and when this pressure rises above a predetermined pressure, the boiled water is introduced into the upper container 3 through the pipe section 4 and the coffee. It mixes with the powder and the coffee liquor is extracted. Then, when the heater is turned off, the temperature of the lower container 1 is lowered, the internal pressure is lowered, and the extracted coffee liquid in the upper container 3 flows down into the lower container 1. When all the coffee liquid in the upper container 3 has been flowed down into the lower container 1, the base end 6a of the lever 6 is moved to the arrow A with the thumb while grasping the handle 2.
When it is pushed and rotated in the direction, as shown in FIG. 2, the tip portion 6b of the lever 6 contacts the lower surface portion of the upper container 3 and pushes the upper container 3 upward, and the packing 5 opens. 1
The upper container 3 is released from the press-fitted state for a and the upper container 3 is released from the airtight state for the lower container 1. Then, the upper container 3 is held by hand and pulled up to be removed from the lower container 1. Then, by holding the handle 2 of the lower container 1, the coffee liquid inside is injected and distributed into an appropriate container.

According to this embodiment having such a configuration, the following effects can be obtained.
That is, the handle 2 is provided with a lever 6 as a pushing-up means, and by operating the lever 6, the upper container 3 can be pushed upward and released from the airtight state with respect to the lower container 1. It can be easily removed from the lower container 1 simply by pulling it upward. Therefore, unlike the prior art, since it is not necessary to pull up the upper container 1 strongly, the pipe portion 4 of the upper container 3 does not collide with the opening portion 1a of the lower container 1 due to the reaction at the time of release, and the pipe portion 4 Can prevent damage. Also, when removing the upper container 3,
Since it suffices to hold the upper container 3 lightly by hand and pull it upward, even if the upper container 3 after the extraction of the coffee liquid is in a high temperature state, it does not cause a burn on a finger.

The present invention is not limited to the embodiments described above and shown in the drawings, and various modifications can be made without departing from the scope of the invention.

[Effects of the Invention] As is apparent from the above description, in the present invention, the handle of the lower container is provided with the push-up means for pushing the upper container to release the airtight state from the lower container. There is an effect that it can be easily removed and damage to the pipe portion of the upper container can be prevented.
