2. Description of the Related Art Coffee liquid dropped from a coffee extractor is stored in a glass pot through a central hole of a pot lid. The lid is made of a plastic molded product in which a short cylindrical body hangs on the lower surface of the top plate portion. Then, at several places in the circumferential direction of the short cylindrical body, notches parallel to the central bearing of the cylindrical body are provided, thereby forming a tongue portion that is elastically bendable in the radial direction, and a protrusion is formed on the outer periphery of this portion. Provided, and these protrusions were fitted inside the glass pot.
Example).

Further, since the coffee liquid stored in the coffee receiving container is in contact with the air (oxygen) outside the container, the components of the coffee liquid are oxidized and the coffee is deteriorated, and the clear liquid becomes cloudy and astringent. The taste and sourness increase, and the unique scent of coffee decreases to a muddy smell, and the commercial value is lost in restaurants and the like.

A conventional technique for solving such a problem is disclosed in, for example, Japanese Patent Application Laid-Open No. 57-128116 (second conventional example). That is, in combination with a decanter (pot) having an opening upper end and adapted to contain a substantial amount of coffee whose vapor pressure exceeds atmospheric pressure, a top assembly (lid) for closing the opening upper end, In order to distribute the stored coffee from the bottom of the decanter to the outside, a pouring pipe extending from the bottom of the decanter to the upper end and the above decanter are ventilated to maintain a pressure exceeding atmospheric pressure inside the decanter during coffee storage. , Consisting of a small lid with small air holes.

As another example, as disclosed in Japanese Patent Application Laid-Open No. 2-98322 (conventional third example), a coffee container for storing coffee liquid extracted from coffee beans and an opening of the coffee container can be freely attached and detached. A coffee container lid attached to the coffee container lid, the coffee container lid has an airtight joint with the opening of the coffee receiving container, a coffee liquid receiving portion to be extracted, and the coffee liquid received by the receiving portion is placed in the coffee receiving container. An inflowing liquid trap and a coffee liquid pouring portion formed in a portion for the liquid trap opening on the receiving portion side are formed.

However, the first conventional example has the following problems. That is, it is generally said that glass molded products have poor dimensional accuracy, and in particular, the inner dimensions are not uniform because the wall thicknesses are uneven.
Since the lid is held by the elastic deformation of the tongue piece on the inner wall whose dimensions are not fixed and the lid itself is softened by heat, it is uncertain how to hold the lid. When pouring coffee, the lid may fall off due to being pushed by the coffee, and at the same time a large amount of coffee may flow out, which is dangerous.

Also, in the prior arts of the second and third examples,
None of them can discharge all the coffee liquid stored in the pot, and a certain amount of coffee liquid always remains.

An object of the present invention is to solve the above problems and to provide a coffee liquid storage device in which deterioration of coffee liquid due to oxidation is minimized and the coffee liquid does not remain.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below based on an embodiment shown in the drawings. In FIG. 1, a conventionally known coffee liquid extractor 1 is provided with a drip port 1b at the top of a main body 1a and a pot base 1c at the lower end, and the coffee liquid storage device A according to the present invention is placed on the pot base 1c. It

2 to 5, in the coffee liquid storage device A, the lid body 3 is detachably fitted to the upper end of the pot body 2 and the handle 9 is provided on the side surface. The lid main body 3 has a funnel portion 3a at a central portion, and an annular groove portion 3b is continuously provided on the outer side in the radial direction of the funnel portion,
A circular groove 3g is formed on the outer circumferential surface so that the circular flat plate portion 3c and the circular packing 8 can be fitted to the outer side of the circular groove portion in the radial direction.
The packing sandwiching annular portion 3f having the above is continuously provided. Then, the silicone rubber elastic packing 8 is fitted into the circumferential groove 3g.

Then, the annular flat plate portion is cut out in a partial range in the circumferential direction to form the spout 3d, and the annular groove portion at a position corresponding to the spout has a bottom portion up to the height of the spout. It is lifted up to become a hill portion 3e. The spout 3
An opening / closing plate 4 is attached to the lid body via a bracket 5 and a pin 6 so as to swing vertically so as to cover d. An injection cylinder 7 is connected to the lower end of the center of the funnel portion 3a of the lid body and hangs down.

The usage state will be described above. The coffee liquid dropped from the dropping port 1b of the extractor 1 flows through the funnel portion 3a of the lid body 3 into the pouring cylinder 7 and is stored in the pot body 2. At this time, the liquid level of the stored coffee liquid is shielded from the atmosphere except for the portion of the injection cylinder 7, and deterioration of the coffee liquid due to oxidation is suppressed to a minimum. Although the portion of the injection cylinder 7 communicates with the atmosphere, it has an extremely small area with respect to the entire area, so that deterioration can be suppressed to a minimum as in the above case. When pouring into the cup or the like from the pouring port 3d, the opening / closing plate 4 opens due to the gravity of the liquid (FIG. 6), and the entire liquid can be completely discharged.

FIG. 7 shows another embodiment in which the circumferential groove portion 3b is removed and the portion becomes an annular flat plate portion 3c.

That is, in FIGS. 8 to 11, in the lid body 10, there is a funnel portion 11 in the central portion, and an annular flat plate portion 12 is continuously provided on the outer side in the radial direction of the funnel portion. The enclosure member 13 is integrally projected. The three-way enclosure member 13 is close to the spout corresponding portion 12a of the annular flat plate portion 12 and is open at the spout corresponding portion side. A cylindrical portion 14 is concentric with the annular flat plate-shaped portion 12 and is separately attached to the lower surface thereof, and a part of the cylindrical portion 14 is cut out on the open side of the three-way enclosure member 13 and fitted to the outer side surface thereof.

In addition, in FIGS. 8, 9 and 10, the packing sandwiching annular portion 15 is concentric with the circular center of the cylindrical portion 14 and integrally formed at the lower end thereof. In this packing sandwiching annular portion 15, a crescent portion 15d is integrally formed on the inside of the annular body 15a in the radial direction of the portion corresponding to the spout corresponding portion 12a. Then, a pouring notch 15c is provided on the outer side in the radial direction. Further, a packing groove 15b is provided on the outer circumferential surface of the annular body 15a and on the pouring notch 15c side of the crescent portion 15d so that the packing 16 can be fitted therein. In the packing 16, as shown in FIG. 13, a crescent portion 16b is integrally formed on the inner side in the radial direction of the portion corresponding to the spout corresponding portion 12a of the annular body 16a, and a pouring notch 16c is provided on the outer side in the radial direction. To be

In the packing sandwiching annular portion 15, a gate-shaped portion 15e is provided inside the crescent portion 15d in the radial direction.
It is integrally formed to form 5 g. Then, the three-way enclosure member 13 is in contact with the upper side of the spout 15g so as to surround it on three sides. An opening / closing plate 21 with a ledge 22 is attached to the inside of the gate portion. That is, as shown in FIG. 10, the main body 21a of the opening / closing plate 21 has a rectangular shape, and when the pot bottom is maintained in a horizontal state, the main body 21a is extended and supported on the crescent moon portion 15d and is supported by the gate portion 15e. Spout 1 formed by
5 g and the pouring notch 15 c of the annular portion 15 are covered from above.
A swing shaft 21b is integrally projectingly provided on both end surfaces near the inner end, and a long hole 2 parallel to the end surface is provided near the inner end.
1c is provided.

Then, the weight 22 is attached to the elongated hole 21c. The weight 22 has swinging shafts 22b and 22b integrally projecting from both long sides of one extension of one short side of a main body 22a made of a rectangular plate. The main body 22a penetrates the long side 21c of the opening / closing plate and is supported by the swing shaft 22b. The swing shafts 21b and 22b of the opening / closing plate 21 and the weight 22 are rotatably positioned and supported in a bearing notch 13b provided in the three-way enclosing member 13 and a bearing notch 15h provided in the gate-shaped portion 15e.

Mounting arms 15f are integrally formed between both side surfaces of the gate-shaped portion and the annular body 15a and toward the inner side in the radial direction opposite to the pouring notch 15c. A set screw 18 penetrating vertically through these mounting arms 15f is screwed into the mounting tube 12b of the annular flat plate portion 12 to fix the packing holding annular portion 15 together with the cylindrical portion 14 to the annular flat plate portion. At this time, the lower surface of the three-way enclosure member 13 and the upper surface of the gate-shaped portion 15e coincide with each other.

This embodiment has the following effects. (1) When the coffee liquid is poured, the coffee liquid flowing out hits the back side of the opening / closing plate 21 and flows out so as to spread on both sides, but the effect of the enclosure member 13 can prevent the coffee liquid from spreading. Therefore, it becomes easier to pour into the cup. (2) Since the opening is covered by the lid body and the surrounding member, adhesion of dust and the like can be prevented. (3) By the method of fitting the packing 16 into the groove of the packing holding annular portion 15, the packing itself can be attached / detached to / from the groove by elastic deformation of the packing itself without attaching / detaching a screw or the like. This is extremely beneficial. That is,
Since the packing has a tendency to bend over time and its holding power decreases, the packing body is pushed by the liquid when the coffee is poured and the lid body falls off, so it is necessary to easily replace it as a consumable item. Also, since the residue of coffee sticks, it is necessary to frequently remove the packing and wash it.

The present invention is not limited to the examples and embodiments described above, but includes various modifications without departing from the spirit and scope of the claims.
