Description

[Detailed Description of the Invention] The present invention relates to an extraction device for coffee, tea, etc., which reduces the amount of coffee, tea, etc. powder used to obtain a large amount of extracted liquid, and eliminates liquid leakage immediately after draining. In addition, it is an object of the present invention to provide an extraction device that can easily determine the extraction state.

Conventional extraction devices of this type simply store coffee or tea powder, etc., spray hot water directly onto the powder, etc. from above, and then discharge the extracted liquid through a drip opening at the bottom of the container. It was something to collect.

In this case, if the amount of powder used is small, the filtration time is correspondingly short and only an extract with a low concentration can be obtained, making it impossible for a small number of people to collect a small amount of a highly concentrated extract. In order to obtain an extract with an appropriate concentration, it was necessary to increase the amount of powder used and prolong the filtration time to obtain an extract with an appropriate concentration.

However, with this type of method, even though the powder itself still has sufficient ability to extract components, there is a waste of discarding the powder as a used powder.

The present invention solves the above-mentioned conventional drawbacks, and the embodiments of the present invention will be described below with reference to Figures 1 to 3. Container 2 is placed on glass container 1 and contains coffee,
Alternatively, it is a basket for storing tea powder, etc., which has a cup shape with a slightly flattened lower part and an almost inverted truncated conical shape, and has a 7-round flange 3 on the outer periphery for placing it on a glass container 1. There is. Reference numeral 4 denotes a handle that protrudes from the edge of the basket 2, and the assistant 11111 of the basket 2 is provided with a cutout groove 6 extending from the edge to the bottom surface. 6 is provided at the bottom of the notch groove 5/ζ dripping]-1, and this dripping port 6 is
One end of a telescopic hollow hose 7 is attached to the lower part, and the other open end 8d is located above the drip opening 6.

Reference numeral 9 denotes a substantially U-shaped operating lever, with an operating piece 10 located outside the basket 2, and the other end of which is engaged with the opening end 8 of the hollow hose through the dripping port 6.

Reference numeral 11 denotes a concentration gauge protruding outward from the basket 2, and both ends of the gauge are connected to the inside of the basket 2 at the bottom and the upper edge thereof, and are connected to the inside of the basket 2. <It is tube-shaped and made of transparent synthetic resin.

In the above configuration, when boiling water is sprinkled on the powder from one side, the extract containing the powder components is transferred to the notch groove 5 and the filter paper 1.
2 and the inner wall surface 13 of the basket.

This residence time is determined by operating the operating piece 10 of the operating lever 9 at the open end 8.
It can be freely adjusted by making it higher than the drain port 6.

In this case, the extract liquid has naturally entered the concentration gauge 11 as well.

Since the concentration gauge 11 protrudes outside the basket 2 and is transparent, the concentration of the extract can be easily determined visually.

Therefore, by adjusting the liquid residence time by moving the operating lever 9 while adjusting the extract liquid concentration on the concentration gauge 11, the user can collect an extract according to his/her preference.

In addition, in order to eliminate the retention of the extract in the basket 2,
It is sufficient to push down the operating lever 9 and position the hollow hose opening end 8 to the outlet 11'106.

Furthermore, if the operating lever 9 is lifted after the extraction is completed, the residual extraction liquid will no longer come out from the dripping port 6.

FIG. 3 shows another embodiment of the transparent concentration gauge 11.
is attached to the basket 3 in a water-tight manner or integrated with the basket 2 and/or molded with transparent resin. In this case, the gauge 11 kl: is visible to the user from outside the basket 2, and 1) has a volume enough to store the liquid 11 and allow the concentration of the extract to be judged.

As is clear from the above description, according to the present invention, the concentration of the extract in the basket can be easily checked visually, and when the extract reaches the desired concentration, the extract can be discharged from the dripping port. can be added dropwise, an extract of a desired concentration can be easily obtained, and leakage of the liquid after the extraction is completed can be prevented, and its industrial value is enormous.
