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, and the number of assembling steps at the time of use is large. 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 in the cup, the coffee pack does not easily sink into the hot water due to its buoyancy and the hot water permeates 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 end 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 and the overall shape of the coffee pack is deformed and it is no longer possible to push the pack part into the hot water. The drawback is that it cannot be done smoothly and the water pressure of the hot water in the cup compresses the pack part in the hot water to reduce the volume inside the pack and reduce the amount of hot water entering the pack, which reduces the coffee extraction efficiency. Was also occurring. Moreover, in the case of a flat bag-type coffee pack, the cavity inside the pack was small and only a small amount of hot water for extraction entered the pack, making extraction difficult. In addition, when the knob part provided on the filter is formed integrally 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 your hands get wet or your 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 atmospheric pressure of the air in the pack hinders the penetration of the hot water and makes it difficult for the hot water to flow into the pack.
