[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drip bag in which an upper portion of a bag body is opened and drip coffee or the like can be easily poured by pouring hot water.

[0002]

2. Description of the Related Art One of the typical methods of brewing coffee is a drip method. The drip method is a method in which coffee powder for the number of people is put into a strainer bag such as a cotton flannel, and hot water is poured from above, steamed and swelled, and subsequently hot water is poured to obtain a coffee powder extract.

[0003] The drip method is widely used as a method for obtaining delicious coffee relatively easily. However, in recent years, it is a disposable coffee drip bag that can easily make coffee without using any special equipment and without any trouble, and that can make delicious coffee according to the original drip type. As what can be done, as shown in FIG. 7, a so-called tea bag-shaped coffee bag 1 in which coffee powder 3 is sealed in a leaching bag 2 made of a water-permeable filter sheet is used. Leaching bag 2
A hanging thread 5 with a tag 4 is attached to the upper edge of the tag.

[0004] When using such a coffee bag 1, first put the brewing bag 2 into a cup, pour hot water, immerse the whole brewing bag 2 in hot water, and if necessary, hang the 2 is moved up and down to promote the extraction of coffee, and then the leach bag 2 is pulled up from the cup with the hanging thread 5.

[0005] Further, with respect to the above-described coffee bag 1,
A drip bag 10 shown in FIG. 8 is also used to make it possible to easily put delicious coffee in a method closer to the original drip type. This drip bag 10 also contains the coffee powder 3 in a bag body 11 made of a water-permeable filter sheet. The upper portion 11a of the bag body 11 can be opened by perforation or temporary fusion. (FIG. 7A). In addition, as shown in FIG.
The locking member 12 that locks the locking member 1 is attached.

The locking member 12 of the drip bag 10
Although various configurations have been proposed as the configuration of (1), generally, as shown in FIGS. (A) and (b) of FIG. The recess 13a is caused to be raised, and the locking piece 13 is locked to the upper edge of the cup, and the locking piece 13 is connected to the folding line 14 by a broken line 14,
A support 15 that supports the locking piece 13 is used.

When making coffee using the drip bag 10, as shown in FIG.
The upper portion 11a of the bag 1 was opened, the locking piece 13 was raised from the locking member 12, and the locking piece 13 was put on the upper edge of the cup 20 to lock the bag body 11 to the cup 20 and opened. Hot water is poured from the upper part 11a of the bag body 11.

[0008]

However, according to the drip bag 10 shown in FIG.
After the hot water is poured into the cup 20 and the hot water is poured, the bag body 11 must be left still until the coffee is extracted to a predetermined concentration. In order to adjust the coffee extraction speed and the finished concentration, FIG. Cannot be moved up and down in hot water like the coffee bag 1 in the shape of a tea bag shown in FIG.

After the extraction, the upper part 1 of the bag body 11 is removed.
When the user drops the liquid drop and discards it by pinching 1a or the locking member 12, there is a danger of burns due to steam or high-temperature water touching the hand. Further, when the locking member 12 is pinched, the bag body 11 may be tilted and the coffee powder 3 may spill into the cup 20.

On the other hand, the tea bag-shaped coffee bag 1 of FIG. 7 does not cause such a problem after the completion of extraction, but the flavor of the obtained coffee extract is inferior to that of the drip bag 10 of FIG. In addition, since the brewing bag 2 rises during the extraction, the extraction liquid cannot be sufficiently leached from the coffee powder 3 simply by leaving it in the cup into which hot water has been poured. There is a problem that the bag 2 must be pressed.

The present invention has been made to solve the above-mentioned problems of the prior art, and a drip bag capable of brewing a delicious coffee similar to that of the original drip type is provided. To be able to accelerate the extraction by moving it, after the extraction, without danger of burns, so that the bag body can be safely pulled out of the hot water and discarded, and such a drip bag can be provided at low cost With the goal.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings. In each of the drawings, the same reference numerals represent the same or equivalent components.

FIG. 1 shows a drip bag 10A according to one embodiment of the present invention (FIG. 1 (a) is a plan view, and FIG. 1 (b) is a perspective view showing a state where it is locked to a cup). This drip bag 10A
Has a bag body 11 and a locking member 12 similar to those of the conventional drip bag 10 shown in FIG.

That is, the bag body 11 is formed of a water-permeable filterable sheet, and contains the coffee powder 3 therein. Here, the bag body 11 has two rectangular surfaces facing each other,
The lower side 11c is a ring, and both sides 11d, 1d
1e is joined by heat fusion. In addition, the bag body 11
A temporary fusion bonding portion 11b is formed on the upper portion 11a of the upper portion 11a so that it can be opened (FIG. 7A).

As the water-permeable filter sheet material forming such a bag body 11, a predetermined amount of coffee powder is filled.
Various types of materials that allow coffee to be leached when poured are used. For example, a nonwoven fabric made of a synthetic resin such as polypropylene, polyethylene, or polyester and exhibiting heat-sealing properties is preferable. Further, a laminated material composed of a plurality of different layers may be used as the water-permeable filterable sheet material.

On the other hand, the locking members 12 adhered to the surface of the bag body 11 are provided symmetrically on the two rectangular surfaces of the front and back sides of the bag body 11. The locking member 12 has a recess 13a.
And a support 15 which is continuous with the locking piece 13 along a broken line 14, and is formed by punching a sheet material such as paperboard.

When brewing coffee using the drip bag 10A, as shown in FIG.
3 is caused by the locking member 12, the recess 13a of which is locked to the upper edge of the cup 20, so that the bag body 11 is locked to the cup 20. In this case, the support 15 stably holds the locking piece 13 on the surface of the bag body 11 even after the locking piece 13 is locked to the cup 20.

In the present invention, such a bag body 11
And a locking member 12, the bag body 11 has a rigid string member 3 extending upward.
0 is provided.

Here, as for the degree of rigidity of the string-like member 30, it is necessary that the string-like member 30 stand up in a stick shape by itself. Furthermore, this coffee bag 10A
The bag body 11 to make coffee with the cup 2
0, and when hot water was poured, the one end of the string-shaped member 30 was picked up, and the bag body 11 was pushed up or down in the hot water of the cup 20 to move the bag body 11 up and down. It is necessary to have a rigidity enough to reliably perform against the buoyancy of the bag body 11. Thereby, the degree of coffee extraction can be arbitrarily adjusted as needed. Also, when the drip bag 10A after coffee extraction is discarded, the bag body 11 is cupped by picking up the string-shaped member 30. 20 and can be easily and safely lifted and discarded.

It is preferable that the rigid string-like member 30 itself be appropriately curled. In this case, the direction in which the curled string member 30 is attached to the bag body 11 is as shown in FIG.
As shown in (b), when the upper part 11a of the bag body 11 is opened, one end 30a of the curled string member 30 is opened.
It is preferable to attach so that is located outside the opened bag body 11. Thereby, when pouring hot water into the opened bag main body 11, the hot water can be prevented from being applied to the string-shaped member 30, and the hand can also be gripped when the bag-shaped main body 11 is moved up and down or discarded. The operation of extracting coffee and the disposal of the drip bag 10A after extraction can be performed more safely and easily without being heated by steam.

The size of the string-like member 30 can be appropriately determined depending on its handleability such as ease of pinching. However, even if the string-like member 30 is pinched immediately after pouring hot water into the drip bag 10A, it is not hot due to steam. The length is preferably about 10 to 100 mm.

The material of the string-like member 30 is not particularly limited as long as the rigidity described above can be obtained, and is appropriately selected according to the adhesiveness to the material for forming the water-permeable filter sheet constituting the bag body 11 and the like. be able to. For example, when a nonwoven fabric made of polypropylene fiber is used as the water-permeable filter sheet material, polypropylene is preferable as the material of the string-shaped member 30.

The specific material form of the cord-like member 30 is as follows.
A twisted string, a plastic plate, a tape, or the like can be used, but a twisted string is preferable in terms of cost. In addition, when using a twisted string, it is preferable to perform a heating and pressurizing treatment with a hot plate in order to correct the twist and impart rigidity, and more preferably, to curl the string-shaped member 30, It is preferable to perform the heating and pressurizing treatment by sandwiching between two hot plates having different temperatures. In this case, the temperature of the hot plate is appropriately determined according to the material for forming the twisted string, the degree of curl to be formed, and the like. Usually, the temperature of the hot plate on the low temperature side is 0 to 100 ° C., and the temperature of the hot plate on the high temperature side is 200 to 300 ° C. It is preferably set to ° C.

The attachment position of the cord-like member 30 to the bag body 11 is preferably an upper portion 11a serving as an opening of the bag body 11, and more specifically, for example, one sheet above the temporary fusion-bonded portion 11b. Surface.

Here, the side edges 11d, 11e of the bag body 11
When is joined by heat sealing of the water-permeable filter sheet,
Since the heat-fusible surface of the water-permeable filter sheet is disposed on the inner surface of the bag body 11, the string-shaped member 30 is attached to the water-permeable filter sheet constituting the bag body 11 by heat fusion. At the time of joining, as shown in FIG. 2A, it is preferable that one end of the cord-like member 30 is heat-sealed not to the sheet surface forming the outer surface of the bag body 11 but to the heat-fusible inner surface. .

As shown in FIG. 2B, when the string-shaped member 30 is joined to the bag body 11 at the upper portion 11a of the bag body 11, as shown in FIG. Since the substantial opening area of the sheet is narrowed and it becomes difficult to pour, it is preferable to join the sheet to one of the sheets as shown in FIG.

The attachment position of the string-shaped member 30 to the bag body 11 is determined by the upper part 11 of the bag body 11 as shown in FIG.
In the case of a, it is preferable that the end of the locking member 12 be on the broken line 14 side. As a result, the end 30a of the curled string member 30 is located outside the cup and further away from the upper edge of the cup. Can be protected from exposure. In addition, the string-shaped member 30 is picked up to form the bag body 1.
The reliability and stability of the work when the user 1 removes from the cup 20 and throws it away is also improved.

The drip bag 10A shown in FIG.
It can be manufactured at low cost on a production line as follows.

First, as shown in FIG. 3 (a), a locking member 12 is attached to a long, water-permeable filterable sheet 18 at a position corresponding to when each drip back 10A is developed. And fold it into two in the longitudinal direction of the sheet as shown in FIG. Thereby, the loop becomes the lower end side 11c of each drip back 10A to be manufactured, and the side of the overlapped side becomes the upper part 11a of the drip back 10A. Therefore, on the upper part 11a side,
The two superimposed sheets are heat-sealed to such an extent that they can be easily peeled off to form the temporary fused portion 11b.

On the other hand, as shown in FIG. 4A, for example, a long twisted string 31 made of polypropylene is sandwiched between two hot plates 35 and 36 and heated and pressed. At this time, one hot plate 3
5 is a high temperature of about 200 to 300 ° C., and the other hot plate 3
6 is a low temperature of about 0 to 100 ° C. Then, the twisted string 31 that has been subjected to the heating and pressurizing treatment contracts on the side pressed by the high-temperature hot plate 35, and is curled as shown in FIG.

Therefore, the string-shaped member 30 composed of the twisted string 31 curled as described above is connected to one end of the curl side.
As shown in FIG. 3C, the drip back 10A is heat-sealed to the upper portion 11a of each drip back 10A so as to be positioned outside the bag body 11 when the drip back 10A is opened.

Next, as shown in FIG. 3 (d), the joining by heat fusion of both sides 11d and 11e of the drip back 10A and the filling of the coffee powder 3 are alternately performed. Then, as shown in FIG. 1E, the drip bag is cut into individual drip bags to obtain the drip bag 10A of FIG.

As described above, the drip back 10A shown in FIG.
Although the present invention has been described in detail with reference to the drawings, the drip bag of the present invention is not limited to this and can take various aspects. For example, the string-shaped member 30 may be a straight member having no curl depending on its length or the like. Such a linear cord-like member is used, for example, when the heating and pressurizing treatment shown in FIG.
By setting both the heating temperatures of 5, 36 to about 150 to 250 ° C., it is possible to obtain at low cost.

If necessary, a tag 4 similar to the conventional tea bag-shaped coffee bag 1 shown in FIG. 7 may be attached to the cord-like member 30. That is, the string-shaped member 30 used in the present invention has a rigidity, unlike the thread 5 attached to the brewing bag 2 in the conventional tea bag-shaped coffee bag 1, so that it can be easily picked. Therefore,
The tag 4 unlike the conventional one is not particularly required from the viewpoint of improving the ease of picking the string-shaped member 30, but a tag may be attached as necessary as a display portion of the description, quality, etc. of the product.

In the drip bag of the present invention, there is no particular limitation on the shape, number, mounting position, etc. of the locking members 12. For example, with respect to the position where the locking member 12 is stuck on the bag body 11, in the above-described drip bag 10A, the position of the concave portion 13a where the locking member 12 actually covers the upper edge of the cup is one in the vertical direction of the bag body 11. / 2, but as in the drip bag 10B shown in FIG.
It may be less than half of the vertical direction of the bag body 11.

The shape of the recess 13a is L-shaped in the drip bag 10A described above, but may be I-shaped as shown in FIG.

The broken line 14 that causes the locking side 13a is also inclined with respect to the side edges 11d and 11e of the bag body 11 in the drip bag 10A described above.
As shown in FIG.
It may be parallel to d and 11e.

Further, in the above-described drip bag 10A, the locking side 13a of the locking member 12 is surrounded by the support 15, but the locking piece 13 is not supported as in the drip bag 10C shown in FIG. It does not have to be surrounded by the body 15. The shape of the side of the support 15 is not limited to a straight line,
As shown in FIG. 6, a curve 15a having a plurality of protrusions is formed, and the lower side of the curve 15a is the side 11 of the bag body.
It may be entirely inclined away from e. Thereby, the bag main body 11 can be stably locked to an arbitrary cup regardless of the shape of the cup.

Although the drip bag of the present invention is particularly useful as a drip bag for coffee, the material to be extracted contained in the bag body 11 is not limited to coffee powder. According to the drip bag of the present invention, even when green tea, black tea, herbal medicine, powdered soup and the like are stored, respective extracts can be obtained favorably.

[0044]

According to the present invention, in a drip bag capable of brewing the same delicious coffee as in the original drip type, the string-shaped member is pinched, and the bag body is moved up and down in boiling water at the time of extraction to accelerate the extraction. As a result, the coffee extraction concentration can be easily adjusted. Further, after the extraction, it is possible to pinch the string-shaped member and safely pull up the bag main body from the extraction liquid and discard it.
Furthermore, the drip bag having this string-shaped member can be manufactured at low cost.
