Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a coffee liquid storage device.

[0002]

2. Description of the Related Art Coffee liquid stored in a coffee receiving container is in contact with air (oxygen) outside the container, so that the components of the coffee liquid are oxidized and the coffee is deteriorated. The taste and sourness increase, the unique aroma of coffee decreases and becomes a muddy aroma, and its commercial value is lost in restaurants and the like.

[0003] The first of the prior art to solve such a problem.
An example is disclosed in, for example, JP-A-57-128116. A top assembly (lid) which has an upper end of the opening and which closes the upper end of the opening in combination with a decanter (pot) which is adapted to contain a considerable amount of coffee whose vapor pressure exceeds atmospheric pressure; A spout pipe extending from near the bottom of the decanter to the upper end to distribute the contained coffee from the bottom of the decanter to the outside, and ventilating the decanter so as to maintain a pressure exceeding atmospheric pressure inside the decanter during coffee storage. , A small lid having a small air hole.

[0004] In a second example, as disclosed in Japanese Patent Application Laid-Open No. 2-98322, a coffee container for storing coffee liquid extracted from coffee beans, and a coffee container detachably attached to an opening of the coffee container. A lid is provided, the coffee container lid has an airtight junction with the opening of the coffee receiving container, a coffee liquid receiving portion to be extracted, a liquid trap that flows the coffee liquid received at the receiving portion into the coffee receiving container, And a coffee liquid pouring portion formed at a portion corresponding to the liquid trap opening portion on the receiving portion side.

[0005]

However, in each of these prior arts, all of the coffee liquid stored in the pot cannot be discharged, and some coffee liquid always remains. An object of the present invention is to solve the above-mentioned problems and to provide a coffee liquid storage device in which deterioration due to oxidation of coffee liquid is minimized and coffee liquid does not remain.

[0006]

Means for Solving the Problems To solve the above problems, the configuration of the present invention is as follows. That is, a lid body that covers the upper opening of the pot body, has a funnel portion in the center, and has a spout with a part of the peripheral edge portion cut out, and a vertically swingable portion that covers the spout. An opening / closing plate attached to the lid body, and a dropping cylinder connected to the lower end of the center of the funnel portion of the lid body and hanging down, the lid body has a funnel portion at the center portion,
An annular groove portion is continuously provided radially outside of the funnel portion, and an annular flat plate portion is continuously provided radially outside of the annular groove portion, and a part of the annular flat plate portion in a circumferential direction is provided. The cutout forms a spout, and the bottom of the annular groove at the position corresponding to the spout is raised to the height of the spout.

[0007]

[0008]

Embodiments of the present invention will be described below based on one embodiment shown in the drawings. In FIG. 1, a conventionally known coffee liquid extractor 1 is provided with a dropping port 1b at an upper portion of a main body 1a and a pot base 1c at a lower end, and a coffee liquid storage device A according to the present invention is mounted on the pot base 1c. You.

2 to 5, in the coffee liquid storage device A, an edge cover 2a is attached to an upper end of the pot body 2, and a lid body 3 is detachably fitted thereto. The lid body 3 has a funnel portion 3a at a center portion, an annular groove portion 3b is continuously provided radially outside the funnel portion, and an annular flat plate portion 3c is continuously provided radially outside the annular groove portion. It becomes. Then, the annular flat plate portion is cut out in a part of the circumferential direction of the annular flat plate portion to form a spout 3d, and the annular groove portion at a position corresponding to the spout is raised to the height of the spout so that the height is raised. The section 3e. In addition, a part of the peripheral edge of the annular flat plate portion 3c that is diametrically opposed to the spout 3d is cut out to form a positioning concave portion 3f, and a positioning convex portion 2b that engages with the concave portion is formed on the edge cover 2a. .

An opening / closing plate 4 is attached to the lid body via a bracket 5 and a pin 6 so as to be able to swing up and down so as to cover the outlet 3d. The 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 use 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 main body 3, flows down in the injection cylinder 7, and is stored in the pot main body 2. At this time, the liquid level of the stored coffee liquid is blocked from the atmosphere except for the portion of the injection cylinder 7, so that the deterioration of the coffee liquid due to oxidation is minimized. The portion of the injection cylinder 7 is open to the atmosphere, but has an extremely small area with respect to the whole area.

When the liquid is poured into the cup or the like from the pouring opening 3d, the opening / closing plate 4 opens due to the gravity of the liquid, so that the entire liquid can be completely discharged. By engaging the positioning concave portion 3f of the lid main body 3 with the positioning convex portion 2b of the edge cover 2a, the spout 3d of the lid main body 3 can correspond to the spout 2c of the edge cover 2a.

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 appended claims.

[0014]

According to the configuration of the present invention, the deterioration of the coffee liquid stored in the pot body can be prevented. In addition, all of the coffee liquid stored in the pot body can be discharged from the spout, and the inconvenience due to the residual liquid has been eliminated. Also, a finger can be inserted into the annular groove, the outer periphery of the funnel can be pinched, and the lid body can be attached and detached. In addition, a slight elastic deformation of the annular groove in the radial direction makes it possible to secure an appropriate fitting state and a sealing state to the pot body opening.
