More specifically, the present invention relates to a beverage extraction bag for extracting coffee, tea, green tea, and other drinkable materials with water or hot water. The beverage extraction bag of the present invention has an opening at the upper end, particularly at the time of extraction, and raises a pair of locking pieces to lock the upper edge of a container such as a cup, thereby stably opening the bag. It is suitable for extraction while maintaining.

有していた。2. Description of the Related Art Most of conventional beverage extraction bags contain coffee powder, tea leaves, or the like in a filter paper bag body, and a cardboard support frame is attached to the upper half of both sides of the filter paper bag body. Such a beverage extraction bag is disclosed, for example, in JP-A-4-13568. However, in the beverage extraction bag having the above configuration, the support frame is placed only on the upper edge of a container such as a cup and is not locked, so that the support state of the extraction bag is unstable. Therefore, there is a disadvantage that the extraction bag slips when the hot water is poured from above, and that the extraction bag sometimes comes off the container. Moreover, in the conventional extraction bag as described above, it is difficult to stably maintain the open state, and it is difficult to perform the extraction operation smoothly. Furthermore, in the conventional extraction bag as described above, since the arm of the support frame extends out of the filtration bag, the size of the extraction bag is increased, and therefore, the size of the outer bag that accommodates the extraction bag is also increased. There were also problems such as the increase in size and the economic disadvantage.

The pair of locking pieces 9 of the front surface portion 3 and the back surface portion 4 of the filter bag main body 2 are bent outward at the bending line 11 of the locking piece support portion 8a to raise the locking pieces 9. The raising operation of the locking piece 9 is performed by pivoting the locking piece 9 outward about the bending line 11, and sandwiching the connection side line 12 of the front / back portions 3 and 4 of the filter bag main body 2. This operation is performed by pulling outward on both sides, so that the upper end of the filter bag is naturally opened by this operation. When the gusset 7 is formed at the bottom of the filter bag, the gusset 7 is also extended by the locking piece 9 as shown in FIG. Moreover, the upper and lower shape retaining portions 8b and 8c of the support portion 8 are easily deformed with the expansion of the filter bag main body 2, and can hold the filter bag main body 2 in the expanded shape even when the expansion force is released. it can.

Preferably, ridges 13 are formed. The reinforcing ridges 13 are raised by the locking pieces 9 and the locking recesses 9 are formed.
a, when the weight of the extraction bag, its contents, and the poured water or hot water is applied to the locking piece 9, the locking piece 9 is deformed. This is effective to reinforce this in order to prevent bleeding and to keep the extraction bag in the desired position and shape. The number of the reinforcing ridges 13 is not particularly limited, and one or more, preferably,
Two to five parallel to each other. As shown in FIG. 3, the reinforcing ridge 13 may be formed only at the tip of the locking piece from the locking recess 9 a, or these reinforcing ridges 13 may be It may be extended to the boundary with the support part 8a. The reinforcing ridge 12 may be formed in a corrugated shape. The ridge 10 for reinforcing the locking piece support and the ridge 1 for reinforcing the locking piece
In order to form the corrugated sheet 3 into a corrugated plate, a predetermined shape of embossment may be applied from a back side to a predetermined position of the sheet for the locking member 5, but this embossing process compresses the ridge portion and increases its density. Therefore, the bending rigidity is increased, and the reinforcing effect is further enhanced.

In addition, if the material to be extracted is not stored in the extraction bag in advance, the extraction bag is opened, and after being locked in a container, a desired amount of the material to be extracted is put into the filter bag body, and water or Pour boiling water and extract. Also, when a gusset is provided at the bottom of the filtration bag main body, the filtration bag main body expands into a cylindrical shape or an elliptical cylindrical shape,
Since this shape is stabilized by the reinforcing ridge provided on the locking piece support portion, the locking piece is held in a substantially vertical position, so that the stability of the support state of the filter bag body by the locking piece is maintained. And an efficient steaming effect can be given to the material to be extracted. Further, when a reinforcing ridge is formed on the locking piece, the locking piece can be further reinforced and the locking state can be further stabilized.
