Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a coffee set with a drip point, which is equipped with a hot water cup that is placed over a filter bag containing coffee ingredients and gradually supplies hot water to the coffee ingredients. It is.

[Conventional technology] This will be explained with reference to FIG.

Placed on top of filter bag 7 containing coffee raw material 8,
Conventional hot water cup 9 that supplies hot water little by little
As shown in FIG. 6, a pore 10 for a hot water supply path was provided at the bottom of a hot water supply cup 9, and the hot water supply speed was adjusted depending on the size of this pore.

[Problems to be solved by the invention] In order to provide the pores 10 of the desired inner diameter in the bottom of the hot water supply cup 9, drilling and cutting were required, which was very time-consuming.

This idea makes it possible to easily provide a hot water supply path with a desired flow area at the bottom of a hot water supply cup that is designed to supply hot water little by little.

[Means for solving problems] This will be explained with reference to the drawings.

The drip point coffee set according to this invention is made by connecting both ends of parallel lines 1a and 1a to semicircular arcs 1b and 1b.
Open the opening 1 surrounded by the bottom 2 of the pouring cup 2.
A small vertical groove 4 having a constriction part 4a is provided on the circumferential wall surface of the fitting part 3a of the stopper 3, which consists of a fitting part 3a to be fitted into the opening 1 and an enlarged cover part 3b above the fitting part 3a, and an enlarged cover part 3a. A notch 5 that communicates with the small groove 4 is provided on the lower surface of 3b.

[Function] When hot water is poured into the hot water supply cup 2, the hot water passes through the small groove 4 with the notch 5 and the squeezed part 4a and is poured into the filter bag 7 containing the coffee raw material 8. The speed at which it is poured is determined by the constriction section 4a.

Further, the hot water supply cup 2 and the stopper 3 are made separately and then fitted together, and the hot water supply cup 2 and the stopper 3 are made of synthetic resin and have a shape that can be injection molded, and the dimensions of the constricted portion 4a are adjusted. It is also easy to maintain accuracy.

[Example] 6 is a coffee filter, 7 is a filter bag placed in the coffee filter 6, and 2 is a pouring cup placed on the coffee filter 6.

Reference numeral 1 denotes a through hole provided in the bottom 2a of the pouring cup 2, which has a shape in which both ends of parallel lines 1a, 1a are surrounded by semicircular arcs 1b, 1b.

Reference numeral 3 designates a plug body installed in the through hole 1, which consists of a fitting part 3a that fits into the through hole 1, and a lid part 3b above the fitting part 3a,
Further, a vertical small groove 4 having a constricted portion 4b is provided on the peripheral wall surface of the fitting portion 3a, and a cutout portion 5 communicating with the small groove 4 is provided on the lower surface of the lid portion 3b.

The hot water cup 2 and the stopper 3 are both injection molded from hard synthetic resin, and then the stopper 3 is fitted into the through hole 1 from above.

[Effects of the invention] In this invention, an opening 1 is provided in the bottom 2a of the hot water supply cup 2, a stopper 3 is fitted into the opening 1, and a stopper 4a with a constriction part 4a provided on the peripheral wall surface of the fitting part 3a of the stopper 3 is provided. A hot water supply passage was formed by the vertical small groove 4 and the notch 5 provided on the lower surface of the enlarged lid 3b. For this reason,
There is no need for drilling and cutting of the injection molded hot water supply cup 2, making it easy to form a hot water supply passage with high accuracy. Furthermore, even when the narrow hot water supply passage becomes clogged, it can be easily cleaned by removing the stopper 3 and washing it.
