Abstract

PURPOSE:To facilitate a dripper pack having a bag-like container composed of a front side filter part and a planer frame having a length longer than that of the filter part by charging coffee powder thereinto through the opening of the container, and then temporarily sealing the opening while using the upper part of the planer frame as a nipper. CONSTITUTION:A bag-like container is composed of a front side filter 1 and a rear planer frame 2 longer than the filter 1. Coffee powder 7 is charged into the bag-like container through its upper opening 4, which is then temporarily sealed so as to form a dripper pack. When the dripper pack is used, the pack is set in a cup, and the opening having been temporarily sealed is opened, and hot water is gradually charged into the pack, using the upper inside part of the planar frame 2 as a filling guide surface 6, and coffee liquid is extracted into a cup 9. After the use of the dripper pack, the outer surface 3 of the upper extension of the planar frame 2 is used as a nipping part 5 nipped by fingers so as to gradually draw the pack from the cup 9 while draining the hot water therefrom. Accordingly, coffee can be easily and safely extracted.

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 Heretofore, there have been a drip type placed on the mouth of a cup and a coffee pack type put in a 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 the simple coffee extractor, the filter is on the front side and the back side is a flat plate.The flat plate that forms the bag-shaped container by combining this filter and the flat plate has the upper part extending higher than the filter side and the knob part. A dripper pack which is formed and whose inner surface is also a surface for pouring hot water is filled with coffee powder and the mouth is temporarily adhered.

[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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is a flat bag-shaped structure in which one surface is a filter and the other surface is a flat plate, and these two surfaces are joined together, and there is only one filter surface. The back side functions as a surface frame and holds this bag type inside the cup.The mouth of the bag and the overall shape are deformed due to the weight of the hot water poured into the bag and the hot water is poured into the bag. It prevents it from disappearing. When the surface frame on the back side is bent inward in the cup, the bag mouth portion is opened and formed, and the weight of the hot water in the bag is also supported by the surface frame to keep the bag shape in the cup. The surface frame is bendable by hand and has sufficient hardness to withstand the weight of hot water and is waterproof. The surface frame, which is a flat plate, extends higher than the filter part 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 face frame of the flat plate acts as a heat insulating plate that shields the heat of steam rising from inside the cup and the pack itself when taking out the dripper pack from the cup by manually gripping the grip or the tab. Also, since the filter has only one side, the drip speed is low and it is appropriate. The surface frame, which is a flat plate, uses synthetic resin or waterproof cardboard. Therefore, the present invention has the following features. 1. In the simple coffee extractor, the filter is on the front side and the back side is a flat plate.The flat plate that forms the bag-shaped container by combining this filter and the flat plate has the upper part extending higher than the filter side and the knob part. A dripper pack which is formed and whose inner surface is also a surface for pouring hot water is filled with coffee powder and the mouth is temporarily adhered. 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 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. 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. Further, since the knob portion (5) has the surface frame itself waterproof, when pouring hot water onto the pouring surface (6) located on the outside of the cup (9), the hot water is poured 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, 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.
The surface frame also has the strength to hold the mouth shape and the whole shape when pouring hot water in the cup. Also, the surface frame is insulated from the heat inside the cup or 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.
