Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coffee dip bag in which coffee powder is filled for one cup of coffee, which can be easily and sufficiently extracted when the coffee is poured into a container and hot water is poured. .

[0002]

2. Description of the Related Art Conventionally, a coffee dip bag is made of filter paper or the like as is well known, and is filled with one cup of coffee powder, and a hanging thread is attached to an upper edge portion thereof. . When putting coffee, the user holds the hanging thread, puts a dip bag in a container, pours hot water, and raises and lowers the dip bag to promote coffee extraction.

[0003]

[0005] However, simply moving up and down with the above-mentioned hanging thread depends on only the contact pressure of hot water against the dip bag to extract coffee, so the extraction is not sufficient, and the coffee is again pressed with a spoon or the like. Otherwise, coffee cannot be fully extracted.

[0004] The above-mentioned operation is necessary for drinking coffee deliciously, but there is a problem in etiquette and the appearance is not good.

The present inventor has studied various improvements of the conventional dip bag, devised a dip bag capable of efficiently extracting coffee and tea, and filed an earlier application (Japanese Utility Model Application No. Hei 3 (1994)).
-32101).

This dip bag has a structure in which an extensible tubular body having a closed lower end is inserted into the bag portion and is fixedly fixed to an upper edge of the bag portion. By stirring the bag in a container such as a cup, coffee or tea can be efficiently extracted.

The above-mentioned invention has a remarkable effect in tea, but in powdered coffee, when the powdered coffee comes into contact with hot water, gas is generated. There was a problem that it took time.

[0008] The present invention has been made in view of the above-mentioned circumstances. If a dip bag filled with coffee powder is put into a container and hot water is poured, coffee can be efficiently extracted without using a spoon or the like. It is intended to provide a dip bag that can be used.

[0009]

According to the present invention, there is provided a dip bag comprising a bag filled and sealed with an appropriate amount of coffee powder, a lower tubular body having the outer periphery clamped and fixed to an edge of the bag. A coffee dip bag comprising an upper tubular body slidably inserted into the lower tubular body, and a lower portion of the lower tubular body which is fixedly held at an edge of the bag,
An annular inflatable part is formed, and a lower part of the inflatable part is formed with a constriction whose lower side is gently increased and the upper part is sharpened. Portion is provided, the upper tubular body inserted into the lower tubular body is pulled out, and when the enlarged diameter portion is fitted into the inflated portion of the lower tubular body, mutual movement of the upper and lower tubular bodies is prevented. The lower tubular body has an opening for degassing that is smaller than the inner diameter of the lower tubular body and smaller than the diameter of the coffee powder, and the tubular body is made of Hes by ASTM D648.
Made of synthetic resin with at distortion temperature of 100 ℃ or more.

[0010]

1 and 2 show an embodiment of a coffee dip bag 1 according to the present invention. In the drawings, reference numeral 2 denotes a filter paper, cotton, or synthetic paper whose opening edge is sealed by a seal portion 2a. This is a bag made based on resin. In this bag part 2, one cup of coffee powder 3
Is filled.

At the time of sealing, a lower tubular body 4 is inserted into the bag section 2 above the seal section 2a of the bag section 2 and an outer periphery 4b slightly below the upper end of the lower tubular body 4 is sealed.
Are sealed and fixed to the edge of the bag portion 2 at the same time as the sealing is performed.

The sealed outer periphery 4b of the lower tubular body 4 is formed to be slightly thinner than the lower part 4c of the lower tubular body 4. An annular inflatable portion 7 is formed below the outer periphery 4b. A constriction 8 having a gentle lower portion and a sharp upper portion is formed at the lower end of the expansion portion 7.

From the upper end of the lower tubular body 4, an upper tubular body 5
The lower end of the upper tubular body 5 is provided with an enlarged diameter portion 9. The inserted upper tubular body 5
Is extended, the enlarged diameter portion 9 is fitted into the inflated portion 7 of the lower tubular body, and the mutual movement of the upper and lower tubular bodies is prevented.

The lower tubular member 4 is provided with an opening 4a for venting gas generated when hot water is poured into coffee powder. If the size of the opening is too large, the size of the opening needs to be smaller than the diameter of the coffee powder because the coffee powder penetrates into the dip bag during storage, which is not preferable. The cross-sectional shape of the opening may be circular, square, polygonal, or any other shape, and may be slit-like. For example, in the case of a slit shape, if the width of the slit is smaller than the diameter of the coffee powder, there is no penetration of the coffee powder into the lower tubular body even if the length of the slit is larger than the diameter of the powder.

Although one or more openings can be provided on the side surface of the lower tubular body, the shapes shown in FIGS. 4A and 4B are practical in view of industrial mass production.

Since the average particle size of the coffee powder is generally about 50 mesh, the size of the opening may be smaller than 50 mesh in this case.

Also, the lower tubular body 4 is connected to the upper tubular body 5
Is inserted, and the lower tubular body 4 is fixed to the opening edge of the bag portion 2 to form the dip bag 1 having the tubular body 6 including the upper and lower tubular bodies 5 and 4.

The tubular body 6 is provided with a Heart Distor by ASTM D648 so that the strength of the waist is not reduced by hot water.
It is made of a synthetic resin having an action temperature (Td) of 100 ° C. or higher.

In order to put coffee using the dip bag 1, as shown in FIG. 3, the upper tubular body 5 is pulled out,
The enlarged diameter portion 9 of the upper tubular body 5 is fitted and locked in the inflated portion 7 of the lower tubular body 4. Next, the bag part 2 is placed in the container 11 and the hot water 12
And the tubular body 6 is swung. The bag part 2
Is fixed only to the outer periphery 4b near the upper end of the lower tubular body 4, so that the bag portion 2 swings with respect to the lower tubular body 4, and the coffee powder 3 is in a state of being stirred by the lower tubular body 4, Since the hot water in the bag unit 2 is exchanged for external hot water, coffee is efficiently extracted. At this time, the gas generated from the coffee is discharged outside through the opening 4a, so that the dip bag is easily immersed in the gate. The extracted dip bag is removed and discarded.

[0020]

As described above, in the dip bag according to the present invention, the extensible tubular body is fixed to the edge of the bag portion, and the tubular body is provided with an opening smaller than the diameter of the coffee powder for degassing. It is compact when not in use,
When used, it is easy to operate because it is extended. Further, the bag portion is easily swung with respect to the tubular body, and the coffee in the bag is stirred and the hot water in the bag is exchanged with the outside, so that efficient extraction is performed. In particular, when hot water is poured, gas generated from coffee is discharged to the outside through the opening, so that extraction is performed more smoothly. Furthermore, since the tubular body attached to the bag is operated, such as pressing with a spoon,
It has the advantage that it doesn't look bad in appearance.
