Abstract

PURPOSE:To facilitate a filter pack in which a bag-like filter 1 made of a filter material is attached at its rear surface with a planar frame longer than that of the filter material, and the upper part of the planer frame is used as a nipping part by charging coffer powder into the bag-like filter through the opening thereof, and temporarily sealing the opening. CONSTITUTION:A bag-like filter 1 is made of a filter material. A planar filter 2 longer than the filter 1 made of a heat-insulating plate 11 is attached to the rear surface of the bag-like filter 1. Coffee powder 7 is charged into the filter 1 through its upper opening 4, which is then temporarily sealed 8 so as to obtain a dripper pack. Upon use of the dripper pack, the pack is set in a cup 9, and then temporarily sealed part 8 is opened so as to use the inside of the upper part of the planar frame 2 as a filling surface 6. Thereafter, hot water is gradually filled so as to extract coffee liquid into the cup 9. After the use thereof, the upper surface 3 of the upper part of the planar frame 2 is used as a nipping part 5 is nipped by fingers so as to gradually draw up the pack from the cup while draining the hot water therefrom. Thereby it is possible to easily and safely extract the coffee.

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. There was also a drawback that if this filter pack was directly held by hand after extraction, it would be hot and that the coffee liquid would make it difficult for the hands to become dirty.

[0004]

Therefore, the present invention has the following features. 1 In a simple coffee extraction device, a flat frame is integrally attached to the back side of a bag-type filter formed by a filter. This flat frame has a width extending to the left and right at the mouth of the bag-type filter and extends upward and downward. The upper part that constitutes the heat insulating plate extends further upward from the bag type filter mouth part to form a knob part, and the inner surface is the hot water pouring surface. This bag type filter is filled with coffee powder and the mouth part is temporarily A close-fitting dripper pack.

[0005]

[Operation] When using the present invention, open the mouth with temporary adhesion and put the whole 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.

[0006]

[Embodiment] The present invention is based on a bag-type filter, in which a set frame for the cup, a knob portion, and a heat-insulating action are integrally formed on the back side of the bag-type filter, and are integrally attached. Since the bag shape is held in the cup, the weight of the hot water poured into the bag prevents the mouth and the whole shape of the bag from being deformed and prevents the hot water from being poured into the bag. When the flat frame on the back side is curved inward in the cup, the bag mouth is opened and held, and the flat frame also supports the weight of the hot water in the bag to keep the bag shape in the cup. The flat frame is hard enough to be bent by hand and can withstand the weight of hot water, and is also waterproof. The flat frame, which is a flat plate, extends higher than the mouth of the filter and serves as a knob when removing this part from the cup, and the inside surface of this knob also functions as a pouring surface when pouring hot water into the bag. The flat frame, which is entirely flat, acts as a heat insulating plate that blocks the heat of steam rising from inside the cup and the pack itself when the dripper pack is taken out from the cup by holding the knob portion by hand. The flat frame, which is a flat plate, uses synthetic resin or waterproof cardboard. Therefore, the present invention has the following features. 1. A flat frame is integrally attached to the back side of a bag type filter formed by a filter in a simple coffee extraction device. This flat frame has a width that extends to the left and right at the mouth of the bag type filter and extends upward and downward to prevent heat. The upper part that constitutes the plate extends further upward from the bag type filter mouth part to form a knob part, and the inner surface is the hot water pouring surface This bag type filter is filled with coffee powder and the mouth part is temporarily adhered Dripper pack doing. 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 capacity difference from 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 bottom of the bag filter and the lower part of the flat frame are fixedly placed on the bottom of the cup, and the weight of the hot water in the bag filter is basically supported by the bottom of the cup. The tab is located close to one end of the mouth of the bag-type filter, so the knob (5) is gripped from the outside. When you hold the coffee pack by hand and take it out of the cup, your hand should be on the outside of the cup or pack. Therefore, the heat rising from the cup or the pack is not directly received by the hand, and the coffee pack can be directly held by the hand. In addition, since the knob portion (5) is waterproof on the flat frame itself, when hot water is poured on the pouring surface (6) located on the outside of the cup (9), the hot water flows from the outer surface (3) to the outside of the cup (9). It does not leak out, and since the knob portion (5) provided at the mouth portion is waterproof, the coffee liquid will not be contaminated by the holding liquid.

[0007]

Since the dripper pack of the present invention pours hot water directly into the pack, the extraction is fast and the bag type filter has a flat frame, so that when pouring hot water, the mouth shape is stable and opens. It has a compact and simple structure that does not require a setting mechanism that extends beyond the filter. In addition, the strength of holding the mouth shape and the whole shape when pouring hot water in the cup is generated by the flat frame, and the flat frame is insulated from the heat in the cup and inside the pack by holding the knob by hand from the outside. The hands holding the Mamoru pack as a plate also protect the 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 in the cup. Coffee powder is deposited downwards and the hot water runs out quickly.
