A liquid storage space 6 is formed around the lower part of the liquid crystal display. The whole is symmetrical about the axis A, so that rotary blow molding is possible. After the extracted coffee liquid once accumulates in the liquid storage space 6, it falls into the container S from the dropping hole 4a, so that the coffee liquid above is drawn down by this and descends at an appropriate speed. . Therefore, even if the filter F is in close contact with the inner surface of the dripper 2, the dropping speed of the coffee liquid does not become inappropriately low.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to a glass coffee dripper for extracting coffee by attaching a paper filter.

[0002]

[Prior art]

 Conventionally, a ceramic or plastic coffee dripper is known. Each of these drippers has two inclined planes which are opposed to each other so as to approach downward in the inner part receiving the filter. A plurality of vertical ribs are formed on these slopes to form a ventilation path between the filter and the filter.

[0003]

[Problems to be solved by the invention]

 If the coffee dripper is intended to be made of glass, the rotary blow molding method is advantageous in terms of manufacturing costs and other overall aspects. However, the structure of the above-mentioned conventional coffee dripper cannot perform rotary blow molding. Accordingly, an object of the present invention is to provide a coffee dripper having a new structure which can be manufactured at a reasonable cost by a rotary blow molding method of glass.

[0004]

[Means for Solving the Problems]

 In the present invention, in order to solve the above-mentioned problem, the cylindrical main portions 2 and 14 that open upward and converge downward and the enlarged portions 3 and 15 that are continuous with the lower ends of the main portions 2 and 14 are provided. When the filter F is mounted inside the enlarged portions 3 and 15, the lower ends of the enlarged portions 3 and 15 are closed, and circular bottom portions 4 and 16 having a plurality of drip holes 4a and 16a are provided. Since the coffee drippers 1 and 11 made of glass are formed so that a liquid storage space is formed around the lower part of the filter F, the whole is symmetrical about the axis A, and the rotary blow molding is possible. After the extracted coffee liquid once accumulates in the liquid storage space in the enlarged portions 3 and 15, the coffee liquid falls from the drip holes 4a and 16a into the container, so that the coffee liquid above is drawn to the container. It descends at a moderate speed. Therefore, even if the filter F is in close contact with the inner surfaces of the drippers 1 and 11, the dropping speed of the coffee liquid does not become inappropriately low.

[0005]

[Embodiment of the invention]

 An embodiment of the present invention will be described with reference to the drawings. 1 is a sectional view of a coffee dripper in use, FIG. 2 is a bottom view of the coffee dripper, FIG. 3 is a perspective view of a use state of the coffee dripper, FIG. 4 is a sectional view of a coffee dripper of another embodiment, Is a plan view of the coffee dripper, FIG. 6 is a front view of a holder of the coffee dripper, and FIG. 7 is a bottom view of the holder of the coffee dripper.

In FIG. 1 and FIG. 3, the coffee dripper 1 is set on a container S such as a server and used with a paper filter F attached. The coffee dripper 1 is integrally formed of heat-resistant glass, and includes a main body 2, an enlarged section 3, a bottom 4, and a handle 5.

As shown in FIGS. 1 to 3, the main body 2 has a conical cylindrical shape that opens upward and converges downward. The inclination angle of the main body 2 is set to be slightly smaller than the inclination angle of any commercially available paper filter. The enlarged portion 3 is continuous with the lower end of the main body 2. The enlarged portion 3 has a short conical cylindrical shape which is coaxial A with the main body portion 2 and is turned upside down. When the filter F is mounted, a liquid storage space 6 is formed around the lower portion of the filter F. .

A circular bottom 4 closes the lower end of the enlarged section 3. The bottom part 4 is continuous with the lower end of the enlarged part 3, is substantially perpendicular to the axis A of the main part, and has a plurality of drip holes 4 a. The three dropping holes 4 a are provided at positions not aligned on a straight line passing through the center of the bottom 4. The bottom 4 includes a bulging portion 4b that is curved in a spherical shape and rises toward the center.

The portion other than the handle 5 of the coffee dripper 1 is formed by rotary blow molding. Therefore, the whole is symmetrical about the axis A, and no ribs or the like are formed on the inner surface of the main body 2. According to the rotary blow molding, the molding can be made thinner and lighter than the molding using the male and female molds. The simple shape makes it easy to clean and sanitary.

When coffee is extracted using the coffee dripper 1, the inclination angle of the main part 2 is slightly smaller than the inclination angle of the paper filter F, so that when hot water is poured, the filter F is deformed into a waveform, and the main part 2 is deformed into a waveform. A gap is likely to be formed between the inner surface and the inner surface of the second 2, and complete close contact is avoided. As a result, the ventilation path 7 is secured.

After the extracted coffee liquid temporarily accumulates in the liquid storage space 6, it falls into the container S from the dropping hole 4 a, so that the coffee liquid located above is drawn to the container S and has an appropriate speed. Then descend. Therefore, even if the filter F is in close contact with the inner surface of the main body 2, the dripping of the coffee liquid does not stop or the speed thereof does not become inappropriately low.

Since the bottom of the filter F is linearly closed, the filter F comes into contact with the bottom 4 almost linearly through the center of the bottom 4. In this case, since the three dropping holes 4a are located at positions that are not aligned on a straight line, even if one dropping hole 4a is closed by the filter F, the remaining two dropping holes 4a are open. Therefore, it does not hinder the dripping of the coffee liquid. The bottom surface of the filter F rests on the bulging portion 4b of the bottom portion 4, so that the bottom surface of the filter F slightly floats above the dropping hole 4a, which also contributes to preventing the dropping hole 4a from being closed.

FIGS. 4 to 7 show a dripper 11 according to another embodiment. The dripper 11 includes a main body 12 made of heat-resistant glass and a holder 13 made of an elastic resin.

The main body 12 includes a main body portion 14, an enlarged portion 15, and a bottom portion 16. The main body 14 has a conical cylindrical shape that opens upward and converges downward. The inclination angle of the main body 14 is set to be slightly smaller than the inclination angle of any commercially available paper filter F (the same as those in FIGS. 1 and 3). The enlarged portion 15 is continuous with the lower end of the main body portion 14.

The enlarged portion 15 has a short conical cylindrical shape which is coaxial A with the main body portion 14 and is turned upside down so that a liquid reservoir space is formed around the lower portion of the filter F when the filter F is mounted. Has become.

A circular bottom 16 closes the lower end of the enlarged section 15. The bottom portion 16 is continuous with the lower end of the enlarged portion 15, is substantially perpendicular to the axis A of the main portion 14, and has a plurality of drip holes 16 a. The three drip holes 16 a are provided apart from each other at positions not aligned on a straight line passing through the center of the bottom 16. The bottom portion 16 includes a bulging portion 16b that is curved in a spherical shape and rises toward the center.

The main body 12 is formed by rotational blow molding. Therefore, the whole is symmetrical about the axis A, and no ribs or the like are formed on the inner surface of the main body portion 14.

The holder 13 fitted to the main body 12 has a flange 17 and a handle 18. The flange 17 has a ring shape and is detachably fitted to a lower portion of the main body 12. The flange 17 includes a plurality of elastic engagement pieces 17a and 17b for fixing to the main body 12. The engagement piece 17 a extends downward from the inner peripheral edge of the flange 17, and is formed such that the lower end is wound around the lower end edge of the main body 12. The engagement piece 17b extends downward from the inner peripheral edge of the flange 17 and is formed such that the lower end contacts the outer peripheral surface of the enlarged portion. Since the elastic engagement pieces 17a and 17b are engaged with the outer periphery at the upper and lower portions of the enlarged portion 15, the holder 13 is held without detaching from the main body. The handle 18 extends obliquely upward outward from the flange 17 and is curved inward at the upper portion.

The coffee dripper 11 is used by hanging a flange 17 of a holder 13 on an upper edge of a container. Other uses are the same as those of the previous embodiment, and coffee can be extracted without any trouble similarly.

The main body 12 can be used alone by constituting a dripper without the holder 13. Further, the holder 13 does not need to include the handle 18.

[0021]

[Effect of the invention]

 As described above, in the present invention, the conical cylindrical main body portions 2 and 14 that open upward and converge downward, the enlarged portions 3 and 15 that are continuous with the lower ends of the main body portions 2 and 14, The lower ends of the portions 3 and 15 are closed, and circular bottom portions 4 and 16 having a plurality of drip holes 4a and 16a are provided. Since the glass coffee drippers 1 and 11 are configured so that a liquid storage space is formed around the lower portion, the entirety is symmetrical about the axis A, and rotational blow molding is possible. After the extracted coffee liquid temporarily accumulates in the liquid storage space formed in the enlarged portions 3 and 15, the coffee liquid drops from the drip holes 4a and 16a into the container. It is drawn and descends at a moderate speed. Therefore, even if the filter F is in close contact with the inner surface of the dripper, the effect of preventing the dripping speed of the coffee liquid from being inappropriately reduced is provided.
