Embodiment
<Overview of drip bag 1>
As a method of extracting a beverage such as coffee using an extraction material such as coffee beans, a powder of coffee beans or an extraction material such as tea leaves such as black tea, green tea and oolong tea is filled in a bag-like bag, and the bag is made of paper There is known an extraction method using a drip method in which coffee components, tea components, and the like are extracted by attaching and fixing to a cup or the like using a fixing tool such as, and pouring hot water into the opening of the bag. Generally, a filter made of paper, non-woven fabric, or the like is used as the material of the bag. However, when extracting a more delicious and delicious beverage, it is preferable that the bag be made of a natural material such as cotton.

However, if the bag is made of a natural material such as cotton, the opening of the bag can not be properly sealed by the conventional method after the extraction material is filled in the bag. That is, natural materials such as cotton are difficult to be sealed by heat, unlike non-woven fabrics that can be easily and steadily sealed by thermocompression bonding, heat sealing, etc. It is difficult to get strength). Although natural materials such as cotton can be sealed by sewing, from the viewpoint that it is necessary to form an opening when pouring hot water, the seal becomes too strong for sewing and the opening can not be easily formed in the bag . Furthermore, in the case of sealing the opening by sewing, it is necessary to easily release the sewn part from the viewpoint of easily forming the opening, so a wide gap depending on the seam pitch may be generated. At the time of storage, the contents of the extraction material may spill out of the bag.

Therefore, as a result of various investigations, the inventor of the present invention configures a portion where the extract liquid extracted from the extraction material leaks with a natural material, and heats the portion to be sealed (the portion where the opening is formed at the time of extraction by drip method). By using a sealable material, it is possible to easily manufacture a drip bag containing an extraction material, and at the time of extraction, it is possible to easily form an opening for pouring hot water, and a drip using a natural material It has been found that it is possible to construct a drip bag that can be extracted by the method.

Therefore, as shown in FIG. 3B, the lead-out portion 310 of the clip portion 30 on one side and the lead-out portion 310 of the clip portion 30 on the other side are brought in opposite directions to each other and fixed to the container 5 Ru. Therefore, the drip bag 1 can be disposed on the container 5 in a stable manner because the drawer portion 310 can be disposed at a substantially point-symmetrical position around the top of the portion 100 in top view. it can.

Then, by pouring hot water into the opening 40 a formed after cutting the header portion 20 along the cutting portion 40, the extract liquid from the extraction material 70 is dropped to the container 5. Here, since the bag body 10 has the substantially conical portion 100, the extract liquid drips into the container 5 from the vicinity of the top of the portion 100.

[Modification of drip bag]
FIG. 4 shows an outline of a variation of the drip bag according to the present embodiment. The drip bag 1a according to the modification has substantially the same configuration and function as the drip bag 1 except that the shape of the bag is different from that of the drip bag 1. Therefore, the detailed description is omitted except for the difference.

The drip bag 1a is configured to have a portion in which the bag body 11 has a substantially oblique conical shape. That is, the bag body 11 is configured to have a portion 104 including a portion having a substantially oblique conical shape and a portion 106 having a substantially cylindrical shape. In the bag body 11, a portion 104 including a portion having a substantially oblique conical shape and a portion 106 having a substantially cylindrical shape are continuous on the opposite side of the apex of the portion 104. The opening 11 a of the bag body 11 is provided at the end of the portion 106 and at the end opposite to the portion 104 side.

And the bag 11 has the sewing part 16 closed by sewing in at least one part of the edge except the opening 11a. For example, the end of the portion 106 (in the side view, the portion 106 has a substantially rectangular shape and one short side portion in the substantially rectangular shape) in side view and the end of the portion 104 sew Closed by The bag body 11 and the header portion 20 are adhered to each other by the fixing portion 50 using, for example, an ultrasonic welding method in the same manner as the drip bag 1 as shown in FIG. 4B. That is, in the drip bag 1a, the short side portion of the header portion 20 and a part of the short side portion of the portion 106 are bonded in a side view, and the end portion region of the long side portion on the portion 106 side of the header portion 20 The portion 106 is adhered, and the short side portions of the header portion 20 which are not overlapped with the portion 106 are adhered.

In the drip bag 1a, the bag body 11 to be filled with the extraction material 70 has a portion 104 which is substantially in the shape of an oblique cone. Therefore, the apex of the portion 104 is biased to one side of the right (or left) in the side view. Furthermore, in the drip bag 1a, the clip portion 30 is adhered to the bag body 11 such that the drawing direction of the lead portion 310 is directed toward the side where the apex is present. That is, in the drip bag 1a, unlike the drip bag 1, the clip portion 30 provided on the outer surface of one surface of the bag body 11 and the clip portion 30 provided on the outer surface of the other surface are the respective ones. It is provided in the same direction as the drawing direction in the front view or the side view of the drawing portion 310.

Thereby, in the drip bag 1a, when the drip bag 1a is attached to the container 5, in a top view, the position where the one lead-out portion 310 is attached to the container 5 and the position where the other lead-out portion 310 is attached to the container 5 Since it is possible to bring the position of the center of gravity of the extraction material 70 closer to a line segment connecting the two, it is possible to suppress the drip bag 1a from being inclined by the weight of the extraction material 70.

(Effect of the embodiment)

Moreover, since the drip bag 1 is divided into the bag body 10 configured using a natural material and the header portion 20 configured using a non-woven fabric, and the header portion 20 is configured using a material that can be sealed by heat. After the bag 10 is filled with the extraction material 70, the predetermined position of the header portion 20 can be heat sealed (note that when the entire drip bag is made of a natural material, heat sealing is difficult, practically It is difficult to achieve a seal that can withstand. As a result, it is possible to easily manufacture a single-use drip bag 1 using a natural material, which was conventionally difficult.

Moreover, although the drip bag 1 according to the present embodiment uses a natural material, it can be easily enclosed in a laminate packaging bag or the like that shuts off oxygen etc. similarly to a conventional drip bag, and can be stored for a long time . Thereby, when the drip bag 1 is used, for example, in the case where the extraction material 70 is coffee powder or the like, the taste, the smell, and the like can be maintained for a long time. Furthermore, since the drip bag 1 according to the present embodiment can be used as a one-time use drip bag, the step of simmering and washing the flannel filter before use, as in the conventional neld lip type extraction, and use There is no need to boil the later flannel filter to wash out the fats and so on of the extract material remaining in the flannel filter, and further immerse the flannel filter in a container containing cold water after boiling and store it in a cool dark It is. Thereby, according to the drip bag 1 which concerns on this embodiment, the coffee etc. of taste with a nel drip type | mold can be very easily done.

As mentioned above, although embodiment of this invention was described, embodiment described above does not limit the invention which concerns on a claim. Furthermore, it should be noted that not all combinations of features described in the embodiments are essential to the means for solving the problems of the invention.
