[0002]

2. Description of the Related Art Conventionally, there are a drip type to be placed on the mouth of a cup and a coffee pack type to be put in the cup for use.

[0003]

The drip type to be placed on the cup has drawbacks in that it is large in size and takes up a lot of storage space, as well as the number of assembly steps required during use, and the adaptability to various types of cup diameters and cups. It lacked the stability above.
In the coffee pack type that is used by putting it in the hot water of the cup, in the method of hanging the coffee pack with a thread and putting it in and out of the hot water of the cup, the coffee pack does not easily sink into the hot water due to its buoyancy and penetrates the hot water into the pack It took a lot of time and effort to make the coffee flow and extract the coffee. Also, in the case of a coffee pack that has a knob for holding the coffee pack directly by hand on the upper edge of the coffee pack, if the knob is held by hand and the coffee pack is forced into the hot water, the air inside the pack, etc. Due to the buoyancy of the coffee pack, the force that the pack part filled with coffee powder floats above the surface of the water acts, deforming the overall shape of the coffee pack and making it impossible to push the pack part into the hot water. The drawback is that it cannot be done smoothly and the water pressure in the cup causes the pack part to compress in the water, reducing the volume inside the pack and reducing the amount of hot water that enters the pack, reducing the coffee extraction efficiency. Was also occurring. In addition, when the knob part provided on the filter is integrally formed with the filter material of the pack part, water permeates from the filter of the pack part to the knob part during coffee extraction, and the hands get wet or the hands get dirty with the coffee extract. There was a problem. Further, when hot water flows into the pack through the filter of the coffee pack, the air pressure in the pack hinders the penetration of the hot water and makes it difficult for the hot water to flow into the pack.

[0004]

Therefore, the present invention has the following features. 1. In a coffee pack in which coffee powder formed in a filter is filled with coffee powder and the coffee pack is placed in hot water to extract and filter the coffee from the coffee powder, hold the coffee pack directly on top of the coffee pack by hand.

EXAMPLES The present invention is a knob part (3) for directly holding a coffee pack by hand so that the coffee pack formed by the filter can be forcibly and freely put in and out of hot water such as a cup. Is attached to the upper end of the coffee pack (Claim 1). Also, when the coffee pack is held directly by hand, hot water or coffee liquid permeates and is transmitted to this knob part (3) during extraction from the filter forming the pack part, so that the hand holding the knob part (3) gets wet or dirty. In order to prevent this from happening, the knob portion (3) is covered with a waterproof film (Claim 3), or the knob portion (3) itself is separately formed of a waterproof material and is formed only by a filter. Even a coffee pack having a knob portion (3) integrally attached to the pack can prevent the hands from getting wet or dirty (claim 5). Furthermore, when the coffee pack is placed in hot water, the air inside the pack will follow the permeation of hot water into the pack, increasing the air pressure inside the pack and obstructing the permeation and inflow of hot water. The coffee pack is provided with an opening that is an inlet / outlet for air in and out of the pack. When the knob (3) is provided on the upper end of the coffee pack and the coffee pack is directly held by hand and forced into and out of the hot water in the cup, a sudden and large buoyancy force and water pressure are applied to the coffee pack and the coffee pack is compressed. The volume inside the pack is reduced and the amount of hot water entering the pack is reduced, which also lowers the extraction efficiency, and the buoyancy causes the coffee cup to be deformed greatly such that the shape of the coffee pack is bent and the pack part can be put in and out of the hot water in the cup. To prevent the coffee pack from being lost or the coffee pack deforming in the cup and sinking the knob into the hot water, the filter is covered with a thin film to reinforce the coffee pack to prevent deformation. In order to maintain the space and three-dimensional shape in the coffee pack with this hard filter, It was. In a coffee pack in which a coffee pack and a knob part (3) are integrally formed with a filter, the knob part (3) and an upper part (5) of the pack part are covered with a waterproof film (8) and attached integrally to the filter. In this case, the coffee powder (4) is deposited on the lower part (6) of the coffee pack, so that the lower part (6) is not easily deformed but becomes a hollow part. The upper part (5) is extracting coffee and water pressure or buoyancy of the coffee pack. The waterproof membrane (8) covering the upper part (5) of the pack and the knob part (3) has the effect of reinforcing the filter on the upper part (5) of the pack (claim 4) during extraction and use. The upper part (5) and the knob part (3) of the coffee pack retain the shape and three-dimensional shape such as the boundary between them, and at the same time, the air hole (2) provided in the upper part (5) of the pack has the upper part (5) of the pack. It also has a function of closing with this waterproof membrane (8) covering it, and is used by providing a U-shaped notch (7) around the air port (2) in the waterproof membrane (8) as a turning portion (9). At the same time, the function of opening the air port (2) is also produced (claim 6). With the above method, a smooth coffee extraction action from the coffee powder filled in the coffee pack and a high extraction efficiency are obtained. 1.
