Embodiments of the present invention will be described below. The present invention is a bag-type coffee pack having a side wall made of a waterproof heat-insulating material, which has a filter portion below the bag portion, and is extracted from coffee powder in the bag by hot water poured into the bag. Coffee liquid is extracted and filtered outside the bag through this filter. In addition, in order to prevent deformation of the bag shape itself and the mouth shape due to the weight of the hot water when the hot water is poured into the bag (5) in the cup (10), the strength of the bag shape holding is poured in the cup in the present invention. It has the strength necessary to support the weight of hot water and retains the overall shape and mouth shape of the bag by adding rigidity to the bag itself, and is particularly a unitary structure that does not have a frame portion. Because it can be dispersed and configured throughout, softness also occurs in the entire bag shape, so that coffee powder is filled in the bag, the bag is manually formed and extracted in the cup, and used for extraction and removal from the cup The side wall of the bag is grasped by hand, and the mouth portion is closed to make it easy to grasp. The portion of the outer surface (12) of the waterproof and heat-insulating surface (2) serves as a knob (11) for removing the bag (5) from the cup (10), and in particular, the knob is not structurally provided on the bag (5). . The inner surface (1) of the knob (11) also functions as a pouring surface (8) for 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 heat-insulating surface (2) is made of synthetic resin or waterproof paper. Therefore, the present invention is as follows. 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). When the present invention is used, the temporarily sealed upper mouth (4) is opened, and the folded part (14) is bent outward from the fold a (13) to be turned inside out to form a round mouth shape and a three-dimensional bag shape. The pack of the bag (5) is formed into a cup (1
After the hot water is poured into the bag and set in the bag, the outer surface (12) which is the side wall of the bag (5), which is the knob (11), is gradually lifted by hand. Use hot water. The bag (5) of the present invention has a cup (1
The cup (1) is fixed to the bottom of the cup (1) while the upper port (4) is tilted in one direction inside the mouth of the cup (10).
A method is adopted in which the flat bag (5) in the cup (10) is stabilized in the front, rear, left and right directions by approaching to the mouth of (0). The bag (5) is in the form of a card having a square shape based on a flat bag shape having two sides and a left side edge (7) and a lower side edge (7). It is an easy-to-manufacture overall shape that matches the coffee filling machine. The lower part of the bag (5) is fixed to the bottom in the cup (10), and the weight of the hot water in the bag (5) is basically set to the cup (1).
This method is supported by the bottom in 0). 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 a knob (11), the knob (11) is picked up from outside and the coffee pack is held by hand. Since the position of the hand when taken out from the inside is outside the cup (10) or the pack, the hand does not directly receive the heat rising from inside the cup (10) or the pack. In addition, since the knob (11) has a waterproof and heat-insulating surface (2) itself, the pouring surface (8) located outside on the cup (10) during extraction.
The hot water is prevented from leaking from the outer surface (12) to the outside of the cup (10) when the hot water is poured. 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. According to the present invention, a knob surface is provided by providing a waterproof surface having a large area on the plane of the side wall surface of the outer surface of the bag portion, and by covering the side wall of the bag (5) with the waterproof surface, the knob by the waterproof action is provided. It prevents the generation of steam from the periphery of the hand to the hand side and suppresses the generation and rise of heat to the hand side with the knob, and constitutes a large-area waterproof heat-insulating surface (2) to reduce the side wall surface itself. This makes it possible to use the knob portion (11). Also, the upper opening (4) of the bag (5) is opened in a circular shape when hot water is poured into the bag (5). Is provided so as to extend further upward from the upper opening (4), and the folded portion (14) having the base as a fold (13) is bent outward to form a double-turned opening. It is used to increase the strength of the part shape.
Reinforcement (15) around the mouth of the upper mouth (4) as shown in the figure
May be attached integrally.

[0006]

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.
