Description

Detailed Description of the Invention

[0001]

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

[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 conventional type that is placed on the mouth of a cup has drawbacks in terms of the number of uses and a complicated structure, and the full pack type that is used by putting it in the cup uses hot water inside the pack through the filter surface. However, there is a problem that it takes time to extract and sufficient extraction cannot be obtained, and it is a bag-type filter pack that is used by putting it in a cup and pouring hot water directly into the pack from its mouth The filter softens and deforms depending on the temperature and weight of the hot water when pouring, and the mouth shape of the bag type filter deforms and closes, making it impossible to pour hot water or the entire bag deforms in the cup and the hot water cannot enter. Moreover, if this filter pack is directly held by hand after extraction, it has the drawback that the coffee liquid will make the hands dirty and difficult to hold.

[0004]

Therefore, the present invention has the following features. 1. Above the bag-type filter, which is a bag-type filter that is composed entirely of filters in a simple coffee extraction device and is a rigid bag-type filter that does not deform the mouth shape and overall shape due to the weight of hot water in the cup. The mouth is shaped like a mouth with a high back side and a low front side.The inner surface on the higher side of the back side serves as the hot water pouring surface, and the outer surface serves as a knob for taking out from the cup. This outer surface is a waterproof surface. A dripper pack that is filled with and closes the mouth to temporarily adhere.

[0005]

[Operation] When using the present invention, open the temporarily sealed mouth, put the entire bag-type filter pack in the cup, and pour hot water into the bag. After extraction, match the inner surfaces of the knobs to the outer surface by hand. Gradually lift the sack filter and use it to remove hot water.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention constitutes a coffee pack with a filter, and has a basic structure of a unitary structure, not the conventional structure of a frame part and a filter part. The bag-type filter is formed by a method that depends on the structure of the bag-type filter itself or that the filter itself has the necessary hardness such as making the filter itself thick, and then the bag-type filter as a whole in the cup and its mouth shape. Keeps hot water pouring and extraction work easy. The outer surface of the knob, which is the surface to be touched by the hands, is waterproof. As described above, this property of the bag-type filter, which has the hardness to withstand the weight of the hot water, prevents the deformation of the mouth shape and overall shape of the bag-type filter in the cup caused by pouring the hot water, and makes it easy to pour the hot water. It is also possible to use a laminated type filter in which a frame material such as flat cardboard is laminated and reinforced to add rigidity to the filter. Alternatively, the filter and the frame portion can be attached integrally to the frame portion. It is also possible to form a bag-shaped coffee pack with this filter, which is formed by providing a street portion for passing hot water in the hollow and blocking the street portion with the filter. Therefore, the present invention has the following features. 1. Above the bag-type filter, which is a bag-type filter that is composed entirely of filters in a simple coffee extraction device and is a rigid bag-type filter that does not deform the mouth shape and overall shape due to the weight of hot water in the cup. The mouth is shaped like a mouth with a high back side and a low front side.The inner surface on the higher side of the back side serves as the hot water pouring surface, and the outer surface serves as a knob for taking out from the cup. This outer surface is a waterproof surface. A dripper pack that is filled with and closes the mouth to temporarily adhere. The bag-shaped filter of the present invention is a flat bag-shaped filter in the cup when the lower part is fixedly placed on the bottom of the cup and the upper mouth side is tilted in one direction inside the mouth part of the cup and brought close to the mouth part of the cup. The filter is stable in all directions. Further, the upper mouth portion is positioned horizontally with respect to the cup mouth portion when set in the cup, which facilitates pouring hot water into the bag. Further, since the bag type filter is a flat type bag type filter, the bag type filter has a small capacity compared to the outer dimensions, and the drip action is caused by the difference in capacity with the cup. The bag-type filter is based on a square shape as a whole, and has an easy-to-manufacture shape that matches the coffee filling machine. The bag-type filter can be used in the cup by making the filter itself hard or by reinforcing the frame of the filter and bag-type filter, or by adding rigidity to the bag-type filter due to the structure of the bag-type filter made of filter material. This prevents the bag shape filter from being deformed by the weight and water content of the hot water and deforming the mouth shape and overall shape of the bag type filter, which hinders the injection of hot water and the extraction of coffee. The entire bag-type filter can be freely formed in the cup and can be set in the cup without the need for the detailed work of operating the frame part as in the past. The bottom of the bag filter is fixed on the bottom of the cup, and the weight of hot water in the bag filter is basically supported by the bottom of the cup. Knob (5) because the knob is located close to one end of the mouth of the bag filter
Hold the coffee pack from the outside and remove it from the cup by holding the coffee pack in your hand. You can hold the knob directly by hand. Further, when the mouth portion is shaped such that one side is high and the other side is low, the inner surface (10) on the high side of the mouth portion can be utilized as a pouring surface (6) when pouring hot water into the pack, which facilitates pouring hot water. Since the outer surface (3) of the knob part (5) is waterproofed to form the waterproof surface (2), when the pouring surface (6) located outside the cup (9) is poured with hot water, the outer surface (3) is The hot water does not leak out from the cup (9) to the outside of the cup (9), and the knob portion (5) provided at the mouth portion has the waterproof surface (2), so that the holding liquid does not stain the holding liquid.

[0007]

Since the dripper pack of the present invention pours hot water directly into the pack, extraction is fast and the bag-type filter has hardness, so that when pouring hot water, the mouth shape is opened stably and a setting mechanism or the like is provided. It becomes a simple structure that does not require.
Also, the strength of holding the mouth shape and the whole shape when pouring hot water is generated in the cup, and the hand holding the pack from the outside with the knob part is also protected from the heat in the cup and the hand holding the pack directly. Protect from coffee liquid. Since the knob portion is provided at the mouth portion, the mouth portion can be flatly closed in one stroke by pinching the knob portion from the left and right sides by hand. Since it is a flat bag type pack, the capacity of the bag is small and the hot water in the cup is easily drained, so that the drip action can be obtained even in the cup. Coffee powder is deposited downwards and the hot water runs out quickly.
