Description

[Detailed Description of the Invention] The present invention relates to an assembly type coffee dripper to which a fan-shaped bag-shaped paper filter, which has been widely used in the past, can be applied.

Various types of coffee drippers using paper filters in the form of fan-shaped bags are known, such as those made of ceramics or those made of plastic, but the present invention uses a waterproof or water-resistant thin piece that can be easily operated. The purpose of this invention is to provide an inexpensive coffee dripper that can be used by stably placing it on a coffee cup of any size after being robustly assembled. The embodiments illustrated in the drawings will be described in detail.

As shown in Figures 1 and 2, a rectangular cylindrical outer frame 1 made of a thin piece of waterproof paper with a thickness of about 0.2 mm is provided on both the front and lower edges of the outer frame 1, and a central part A substantially M-shaped notch 4 is formed with a downward guiding protrusion 2 and recesses 3 on both sides of the guiding protrusion, and a plurality of slits as through holes 5 for coffee liquid to flow down are formed near the lower center. A certain V-shaped receiving part 6 is formed in a size corresponding to the inner diameter of the outer frame 1, and a substantially M-shaped insole 8 is provided with downwardly bent hooks 7, 7 at both ends of the receiving part. hand,
This insole 8 is inserted into the outer frame 1 in such a manner that the hooks 7, 7 are hooked to the edge of the frame to form a square funnel, and in use, as shown in FIG. Place the paper filter f in the shape of a fan-shaped bag, which is commonly used in the past, by folding a perpendicular line extending directly upward from both ends of the base, as shown in Fig. 3. By expanding as an eye, it is formed into a rectangular funnel shape as shown in FIG. 4, and is inserted so as to be supported by the outer frame 1 and the insole 8.

As the outer frame 1, as shown in FIG.
Front and rear flaps A, B with a letter-shaped notch 4, left and right flaps C, D with a horizontal slit 9 near the upper end adapted to insert the hook 7 in the insole 8, and a vertical joining slit 10. A thin piece of waterproof paper or plastic having an auxiliary flap E and a joining hook 11 connected thereto is assembled into a rectangular frame shape with the hook 11 inserted into the slit 10. The insole 8, as shown in FIG.
In addition to forming the hook 7 by the letter-shaped cut, a thin piece of waterproof paper or plastic, in which flaps G and G, which serve as reinforcing pieces 12 on the outer side of the hook 7, are arranged in series is bent into an approximately M-shape. , and when attaching the insole 8 to the outer frame 1, hook the hooks 7 to the upper edges of the left and right flaps C and D of the outer frame 1 while keeping the reinforcing pieces 12 in the frame, and also attach the hooks 7 from the outside from above. It is preferable to insert it into the slit 9.

As explained above, the present invention has the following effects.

(a) Since it is composed of thin pieces, and the outer frame and insole are formed separately and then assembled, they can be handled and handled in a flat state before assembly.
Extremely convenient for transportation and storage.

(b) Since a wedge-shaped rectangular funnel is formed by the V-shaped receiving part and the outer frame, it is possible to use the fan-shaped bag-shaped paper filter that has been commonly used in the past with the same shape as it is.

(c) Since it is made of waterproof paper or plastic thin strip, it is lightweight and can be manufactured at low cost.

(d) It is significantly easier to assemble.

(e) Since an M-shaped notch is formed in the outer frame, it is not only possible to stably place a coffee cup of any diameter, but also to reliably guide the coffee liquid flowing down the inner wall of the outer frame into the cup. can do.

(f) Since the hooks formed at both ends of the insole are hooked onto the upper edge of the outer frame, the insole can be placed on the cup while maintaining the shape of the outer frame stably.
