The conventional type placed on the mouth of a cup has drawbacks in terms of the number of operations and the complicated structure, and in the case of a complete pack type used in a cup, hot water is put into the pack through a filter surface. There is a drawback that it takes time for extraction because it enters and exits, and sufficient extraction cannot be obtained. Also, in a bag type filter pack used by putting it in a cup, hot water is poured directly into the pack from its mouth The drawback is that the filter softens and deforms due to the temperature and weight of the hot water when it is poured, and the mouth shape of the bag-type filter is deformed and closed, making it impossible to pour hot water. If you put the lower part of the bag inside the cup and lean it against the inside of the cup opening, the upper part of the bag is located outside the cup, so the hot water from the bag wall to the outside of the cup Exudation has occurred or, also hand there was also difficult to have dirty drawback in the hot, also coffee solution with a direct hand after extraction the filter pack.

[0004]

Therefore, the present invention has the following features. 1. It is a bag type coffee pack with an open upper opening that is used by putting it in the cup of a regular coffee simple extraction pack.The bottom of the bag is placed at the bottom of the cup and the upper part of the bag leans against the inside of the cup opening. This type of bag (5) has a side wall of a waterproof and heat insulating surface (2) having a waterproof property and a heat insulating property, and this surface has a large area and serves as a knob part (11). ) Is provided with a discharge port (6) for discharging the extract from the coffee powder (9) in the bag to the outside of the bag. The discharge port (6) is closed by the filter (3). The waterproof and heat-insulating surface (2) and the filter (3) form a bag (5), which is filled with coffee powder (9) and is placed above (4).
Is a bag-type coffee pack obtained by temporarily sealing the above, and is a card coffee having a fold line (13) and a folded-back portion (14) extending upward around the upper opening (4).

[0005]

[Operation] When using the present invention, the temporarily sealed upper opening (4) is opened and the folded portion (14) is bent outward from the fold (13) to turn it over to form a round mouth shape or a bag shape. A three-dimensional, flat-shaped bag having a large capacity, and the pack of the bag (5) is set in the cup (10) by pouring hot water into the bag and the knob (11) after extraction. The outer surface (12), which is the side wall surface of (5), is used to drain the hot water by gradually lifting the knob bag (5) by hand.

[0006]

The present invention is a bag-type coffee pack whose side wall is made of a waterproof and heat-insulating material, and has a filter portion below the bag portion, and coffee powder in the bag is filled with hot water poured into the bag. The coffee liquid extracted from is passed through this filter, extracted outside the bag, and filtered. Also cup (1
In order to prevent the bag shape itself and the mouth shape from being deformed due to the weight of the hot water when the hot water is poured into the bag (5) in 0), the strength of the bag shape is maintained in the present invention. The bag itself has the strength necessary to support the weight of the bag and maintain the shape of the bag and the shape of the mouth, and the bag itself has a rigid structure. Since the entire bag shape is softened, the bag side wall is also filled when filling coffee powder into the bag, manually forming the bag shape in the cup, and when extracting or using the bag. This is to make it easy to close the knob with the hand and pinch it. The outer surface (12) of the waterproof and heat-insulating surface (2) serves as a knob (11) when the bag (5) is taken out of the cup (10), and in particular, the knob is not structurally provided on the bag (5). In addition, the inner surface (1) of the knob portion (11)
It also functions as the pouring surface (8) when pouring hot water into the bag, and the knob (11) is manually gripped by the cup (1).
When the dripper pack is taken out from 0), the coffee pack is wrapped with a thread so that the heat insulating plate (2) exerts the function of the heat insulating plate for protecting the hand by blocking the heat of the steam rising from the cup (10) or the pack itself. There is no need to hang it, and the coffee pack can be picked up directly by hand. The waterproof / heatproof surface (2) is made of synthetic resin or waterproof paper. Therefore, the present invention has the following features. 1. This is a bag-type coffee pack with an open top for use in a regular coffee simple extraction pack. The bottom of the bag is fixed to the bottom of the cup and the top of the bag is leaned inside the cup opening. The side wall of the bag is a waterproof and heat-insulating surface (2) having waterproof and heat-insulating properties, and this surface has a large area and serves as a knob (11). The lower part of ()) is provided with an outlet (6) for discharging the extract from the coffee powder (9) in the bag to the outside of the bag, and the outlet (6) is closed with a filter (3). A bag (5) is made up of the waterproof and heat-insulating surface (2) and the filter (3). The bag is filled with coffee powder (9) and the upper opening (4) is temporarily sealed. And a fold (13) around the upper opening (4). And a card coffee provided with upwardly extending out folded portion (14). In the bag (5) of the present invention, the lower part of the bag (5) is placed on the bottom of the cup (10) and the upper upper mouth (4) side is tilted in one direction inside the mouth of the cup (10). The flat bag (5) inside the cup (10) is stabilized in the front, rear, left and right directions by bringing it closer to the mouth. The bag (5) is in the shape of a card with a rectangular shape based on a flat bag-shaped one having two side edges (7) and a lower side edge (7) with the two sides combined. It is an easy-to-manufacture overall shape that matches the machine for filling coffee with coffee. The lower part of the bag (5) is fixed on the bottom of the cup (10), and the weight of the hot water in the bag (5) is basically supported by the bottom of the cup (10). Since the outer surface (12) of the waterproof and heat-insulating surface (2), which is the side wall surface of the bag (5), is provided as the knob part (11), the knob part (11) is gripped from the outside and the coffee pack is held by hand. The cup (10) is located because the position of the hand is outside the cup (10) and the pack when taking it out from the inside.
The heat that rises from inside or inside the pack is no longer directly received by the hand. Further, since the knob portion (11) has the waterproof and heat insulating surface (2) itself waterproof, the outer surface (1) is poured when hot water is poured onto the pouring surface (8) located on the outside of the cup (10) during extraction.
It prevents hot water from leaking out of the cup (10) from 2). In addition, since the knob (11) provided on the outer surface (12) of the side wall of the bag (5) has a waterproof and heat-insulating surface (2) having a waterproof property, the coffee liquid does not contaminate the hand to be held. The present invention
A waterproof surface having a large area is provided on the plane of the side wall surface on the outer surface of the bag portion to form the knob surface. By covering the side wall of the bag (5) with this waterproof surface, the waterproof portion provides a hand from around the knob portion. It prevents the generation of steam to the side and suppresses the generation and rise of heat to the hand side having the knob portion. The side wall surface itself is provided with the knob portion (11) by forming a large area waterproof and heat insulating surface (2). )
It was made possible. Further, the upper mouth (4) of the bag (5) is opened in a circular shape when hot water is poured into the bag (5). This mouth shape is deformed and the mouth is closed so that the hot water cannot be poured easily. Is provided with a folded-back portion (14) which is formed by further extending from the upper opening (4), and the folded-back portion (1) having this base as a fold line (13)
4) is bent outward so as to be doubled inside out to enhance the strength of the mouth shape. Further, as shown in FIG. 2, a reinforcing material (15) is integrally attached around the mouth of the upper mouth (4). The method is also good.

[0007]

According to the dripper pack of the present invention, the hot water is poured directly into the pack, so that the extraction is quick. Also, since the bag (5) itself has rigidity, the mouth of the upper opening (4) is used when pouring hot water. It is a compact and simple structure that does not require a setting mechanism or a frame part that opens stably and extends significantly outside the bag (5). In addition, the strength of retaining the mouth shape and the whole shape when hot water is poured in the cup (10) is generated by the rigidity of the entire bag portion. 10) A large waterproof and heat-insulating surface (2) covers the entire outside of the bag (5) from the heat inside and inside the pack, protecting the hands from the heat and protecting the hands holding the pack directly from the coffee liquid. Since the knob portion (11) is provided on the side wall surface, the mouth portion is also closed flatly in one stroke in which the knob portion (11) is held between the outside and the right and left hands. Since it is a flat-type bag-type pack, the capacity in the bag is small, the hot water in the cup is good, and the drip action can be obtained even in the cup (10). Coffee powder (9) settles down and drains hot water quickly.
