BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a coffee pack for simple extraction of regular coffee.

0002

2. Description of the Related Art Conventionally, there have been two types: a drip type that is placed on the mouth of a cup, and a coffee pack type that is placed inside the cup.

0003

[Problems to be Solved by the Invention] The drip type that is placed on top of the cup has drawbacks such as the large size and the need for a large amount of storage space, and the difficulty in assembling it during use. It also lacked stability at the top. When using a coffee pack type that is placed in hot water in a cup, when the hot water flows into the pack through a filter and permeates, the air inside the pack may obstruct the penetration of the hot water, or the air inside the pack may be affected by the temperature of the hot water in the cup. expands and increases the air pressure inside the pack, making it more difficult for hot water to flow into the pack. Furthermore, if the volume of the filter pack is made up only of filters, the pack is compressed by the water pressure of the hot water in the cup, reducing the amount of hot water that enters the pack, which also reduces coffee extraction efficiency. Furthermore, when extracting coffee by infiltrating hot water through a filter from the coffee powder filled in the pack, it is not easy to extract coffee evenly and uniformly from the entire coffee powder filled in the pack.

0004

[Means for Solving the Problems] The present invention is therefore made as follows. Filter (3) and doorway (2)
A filter case (4) is formed by attaching the surfaces of a thin flat frame (1) having a shape of 100 mm to each other and recessing a space for coffee powder (6) and hot water on one side to form a container part (4). 5) and a filter case (7) are provided, and the top of the filter case (5) is provided with a turning part (8) that extends outward, and the same position as the turning part (8) is provided on the filter case (7) side. A recess (9) communicating with the container part (4) is provided on the side of the pack to allow air to enter and exit the pack.
11) of the filter case (5) provided with the container part (
4) and the container part (4) of the filter case (7) to form a pack space for coffee powder (6) and hot water. A coffee pack filled with (6) and sealed.

[0005]

[Function] When using the present invention, turn over the reversible part (8) of the air openings (11) provided above the filter cases (5) and (7) to open the recess (9) leading to the inside of the pack and let the air out. Open the air port (11) for inlet and outlet, and then hold the upper edge (10) of the filter case with your hand and cup (12).
), put the lower part of the filter case into hot water, and let the hot water flow into the filter case pack from the hot water outlet (2) provided at the front of the filter case through the filter (3). Lift up and pass the filter (3) through the cup (12)
Then, the lower part of the filter case is placed in the hot water in the cup (12), and this is repeated several times to extract coffee from the coffee powder (6) in the filter case pack.

[0006]

[Example] The present invention provides a coffee pack filled with coffee powder with an air hole for air to enter and exit, allowing the air inside the pack to freely flow out and out of the pack, thereby allowing hot water to flow into the coffee pack. In order to ensure smooth inflow and outflow of coffee inside the coffee pack and ensure the extraction of coffee inside the coffee pack, and also to prevent the coffee pack filled with coffee powder from contracting due to the water pressure in the hot water in the cup, the entire coffee pack is framed. The same effect can be obtained by making the filter thicker by reinforcing the filter and securing the volume inside the coffee pack even in hot water. In addition, in order to allow the coffee pack to be put in and out of the hot water in the cup, the overall shape of the filter case is made vertically so that the upper part of the filter case can be held in the hand, and it is also made into a thin plate shape. . As described above, the coffee pack was designed to ensure the ability to extract coffee from the ground coffee and to improve uniform and high extraction efficiency. Coffee packs are made by filling coffee powder into a coffee pack formed by a filter, and then placing the coffee pack in hot water to extract and filter coffee from the coffee powder inside.In this coffee pack, hot water flows into the coffee pack filled with coffee powder. In order to provide more space in the coffee pack, the coffee pack should be placed in a filter (3) that has a space for coffee grounds and hot water.
) is formed by filter cases (5) and (7) that are integrated with a frame for holding the shape of the coffee pack, and the entrance (2) for hot water to enter and exit the pack is flat. It may be provided on the front side of the frame (1), or it may be a net-like plane frame (1) and the mesh may be used as the entrance/exit (2). This entrance/exit (2) has a filter (
3), the filter case (5) and (
7) An air hole (11) is provided above for air to freely flow in and out of the filter case pack during extraction.
The coffee pack consists of a frame and a filter (3) integrated into the pack, which is filled with coffee powder (6) and sealed, and during coffee extraction, the coffee flows into the cup through the air inlet/outlet provided in the coffee pack. In order to prevent the coffee powder from flowing out, the coffee pack is made vertically long and an air vent is provided above the coffee pack to prevent the coffee powder from flowing out. A filter (3) and a thin flat frame (1) with an entrance/exit (2) on each side are attached to each other, and a space for coffee powder (6) and hot water is recessed on one side of the container. (4) and a filter case (7) are provided, and the filter case (5) is provided with a turning part (8) that extends outward at the top of the filter case (7). On the side, there is a recess (9) communicating with the container part (4) at the same position as the turning part (8).
) to allow air to enter and exit the pack.
) Container part (4) of filter case (5)
The container part (4) of the filter case (7) and the container part (4) of the filter case (7) are combined to form a pack space in which the coffee powder (6) and hot water can be placed. ) is filled and sealed. The above are examples of the present invention.

[0007]

Effects of the Invention: In the coffee pack of the present invention, the air inside the pack can go in and out of the pack through the air opening (11) provided in the filter case for allowing air to go in and out, so hot water can freely flow into and out of the pack. Coffee can be extracted smoothly. The filter cases (5) and (7), which are integrated with the filter (3) and the flat frame (1), secure the volume inside the coffee pack, allowing a constant amount of hot water to flow inside the coffee pack without being affected by water pressure even in hot water. is always present, increasing coffee extraction efficiency. The structure is simple because the coffee pack frame and filter are integrated. Since the coffee pack is vertically long and the air inlet/outlet is provided at a high position of the coffee pack, coffee powder does not flow out from the air port (11).Also, since the filter case is vertically long, the upper part of the filter case can be used as a handle. You can freely control the flow of hot water into and out of the coffee pack. In addition, since the overall shape of the coffee pack is made into a flat board-shaped card type with filter cases (5) and (7), the storage of the coffee pack is improved, and the packed layer of coffee powder inside the pack is thinner than the filter surface. As a result, the shape of the pack is such that coffee can be extracted uniformly from the coffee powder (6) inside the pack, and the filter area is also large, making it possible for hot water to penetrate and infuse smoothly into the pack for extraction. The present invention is a coffee pack for regular coffee that can be used regardless of the diameter of the cup because it is placed inside the cup and can easily extract coffee by simply putting it in and taking it out.
