[Prior art]

 Conventionally, coffee drippers have been provided with a drip hole at the bottom of the substantially inverted conical container of the dripper so that the coffee liquid that has passed through the coffee filter paper falls from the drip hole into a lower receiver. Has become.

[0003] The drip hole has a diameter of about 2 to 5 mm, and is usually only one for one or two persons, and usually two to three for two to four persons. For example, when using a dripper with three drip holes to brew coffee for one person, the drip speed was too fast, so-called short steaming time was short, and there was a drawback that it was difficult to produce delicious coffee. Therefore, the pouring of hot water must be done in small batches, which is very inconvenient.

[0004] Coffee is sometimes consumed by one person or enjoyed together by many people. However, ordinary homes are rarely equipped with various types of coffee drippers, such as for one person and many people. Has only a dripper for about 2 to 4 persons, and as a result, when drinking with 1 or 2 persons, it is quite inconvenient due to the aforementioned drip speed problem.

[0005] Grained coffee beans have different particle sizes depending on the equipment used for crushing and personal preference. However, the dripping speed of the coffee dripper is predetermined as described above, It was impossible to adjust the drip speed depending on the size).

Japanese Unexamined Utility Model Publication No. Sho 61-110336 discloses a coffee dripper capable of adjusting a drip speed. However, the degree of serial communication between two through holes is adjusted by sliding sliding. It is difficult to control the operation of the slide, and it is difficult to handle such as clogging and no rotation, too much rotation or disengagement. Is done.

[0007]

[Problems to be solved by the invention]

 The present invention is intended to solve the above-mentioned problems, and it is possible to stop drip or reduce the drip speed as needed when one or two people drink coffee. In addition, the drip speed can be increased when enjoying coffee with a large number of people, the drip speed can be adjusted depending on the degree of grind, and the drip speed can be adjusted easily. It is intended to provide.

[0008]

[Means for Solving the Problems]

 After various investigations to achieve the above object, an outlet cylinder was provided on the bottom plate of the dripper, a screw was cut on the outer periphery of the outlet cylinder, and a receiving lid that was rotatable while being screwed with the outlet was attached. It is very preferable if the opening degree is adjusted by changing the distance between the inner bottom surface of the receiving lid and the outlet of the outlet cylinder, and the coffee liquid is dripped from the drainage port on the side surface of the outlet cylinder. He found himself a coffee dripper.

That is, according to the present invention, an outlet cylinder is protruded downward from the bottom plate, and a receiving lid having an internal thread screwed with an external thread provided on an outer periphery of the exit cylinder is provided on the exit cylinder. It is attached rotatably, the distance between the inner bottom surface of the receiving lid and the outlet of the outlet cylinder is arbitrarily adjusted by screw rotation, and the coffee liquid is dripped from the drainage port provided on the side of the receiving lid. A drip speed-adjustable coffee dripper, which is characterized in that:

[Embodiment of the invention]

 The present invention will be described in detail with reference to the drawings and embodiments. FIG. 1 is a schematic plan view of one embodiment of the dripper of the present invention. FIG. 2 is a front sectional view showing a horizontal center section of the embodiment of FIG.

[0011] As shown in these figures, in the present invention, an outlet cylinder (3) is protruded from a bottom plate (2) of a container (1), and a receiving lid (4) is provided on the outer periphery of the outlet cylinder (3). ) Is mounted rotatably by screwing. Incidentally, (5) in the figure shows an annular leg.

FIG. 3 is a partially enlarged cross-sectional view showing the main part of the present invention, that is, the vicinity of the outlet cylinder of FIG. 2 in detail. As shown in this figure, an outer thread (6) is provided on the outer periphery of the outlet cylinder (3) projecting downward from the bottom plate (2), while the receiving lid (4) is provided with the outer screw (4). It has an inner screw (7) screwed into the outer screw (6) on the inner circumference.

[0013] That is, by rotating the receiving cover (4) with the external screw (6) and the internal screw (7), the receiving cover (4) moves up and down, and the inside of the receiving cover (4) is rotated. The distance between the bottom surface (8) and the outlet of the outlet cylinder (3) expands or contracts to change the degree of opening, and the amount of coffee liquid to be discharged, that is, the drip speed changes.

A drain port (9) is provided on the side surface of the receiving lid (4), and the coffee liquid is dropped from the drain port (9). Although FIG. 3 shows an embodiment in which a total of two drainage ports (9) are provided, one each on the left and right sides of the receiving lid (4), the present invention is not limited to this. The drain port (9) can be formed in the lower side of the lid (4).

If a cushion plate (10) is provided on the inner bottom surface (8) of the receiving lid (4) as shown in FIG. 3, it becomes suitable for stopping dripping of the coffee liquid. That is, when it is desired to close the outlet of the coffee liquid by screwing up the receiving lid (4), the closing can be completely achieved with the cushion plate (10).
