Abstract

PURPOSE:To accelerate the extraction of coffee and facilitate the disposal after extraction by integrally superposing a paper filter on an aluminum foil having a plurality of holes, forming the paper filter into a bag shape and forming a pair of knobs on the opposed surfaces of the opened port part in the upper part of the bag. CONSTITUTION:An aluminum foil 2 having a plurality of holes is formed to a bag shape, and a paper filter 1 is superposed to the inside to form integrally, and a coffee bag is formed. On the opposed surface sides of the upper port 4 of the aluminum foil 2, knobs 5 and 6 are installed in extension. Accordingly, the extraction of coffee is accelerated, and the demounting and disposal of the coffee bag after extraction can be facilitated.

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 cost, and in the pack type that is used by putting it in the cup, hot water flows in and out of the pack through a filter. There was a drawback that extraction took time and sufficient extraction could not be obtained. Also, when pouring hot water by pouring hot water directly into the pack from the mouth with a bag type filter pack used by putting it in a cup There was a defect that the filter softened due to the temperature and weight of the bag and the mouth of the bag type filter closed and the entire bag was deformed in the cup so that hot water could not enter, and it was hard to hold it hot by hand after extracting the filter pack. There were also drawbacks.

[0004]

Therefore, the present invention has the following features. 1. In a simple coffee extractor, the filter and aluminum foil surfaces are attached together, and the aluminum foil has a hole for hot water to pass through. This filter and the aluminum foil are integrated into a bag shape. Dripper pack that is used by forming a coffee pack of and forming coffee powder inside. 2. It is a bag-type filter, and the upper mouth (4) is notched on the left and right sides, and the flat parts located on the front and back sides are filled with coffee powder (7) while forming the knobs (5) and (6). A dripper pack in which the mouth is flatly closed by the temporary contact part (8) and temporarily adhered.

[0005]

[Operation] When using the present invention, open the mouth and put the whole bag-type filter pack into the cup and pour hot water into the bag. Gradually lift and drain with hot water.

[0006]

[Example] The present invention is an aluminum filter in which an aluminum foil is laminated on the filter, and even if the pack is held by hand after extraction, the aluminum surface prevents the hand from getting soiled with coffee liquid and the pack is held by hand. The heat of the aluminum is reflected and the heat inside the pack goes out of the pack or the rise in the cup is blocked by the pack body to protect the hands located at the top from the heat and also to keep the inside of the pack warm during extraction. An aluminum film having a thickness of about 15 μm was poured onto the filter to keep the mouth shape and the whole shape of the bag-type filter in the cup so that the hot water could be poured easily. 1. In a simple coffee extractor, the filter and aluminum foil surfaces are attached together, and the aluminum foil has a hole for hot water to pass through. This filter and the aluminum foil are integrated into a bag shape. Dripper pack that is used by forming a coffee pack of and forming coffee powder inside. 2. It is a bag-type filter, and the upper mouth (4) is notched on the left and right sides, and the flat parts located on the front and back sides are filled with coffee powder (7) while forming the knobs (5) and (6). A dripper pack in which the mouth is flatly closed by the temporary contact part (8) and temporarily adhered. The above is the embodiment of the present invention. By attaching aluminum foil to the filter as a unit, the filter is reinforced and the bag type filter can be freely formed in the cup, eliminating the need to attach a frame to the filter as in the past.
The bag-type filter is an inverted conical type that is placed on the bottom of the cup and has a narrow lower side and a large upper mouth side. .. A metal foil or heat-reflecting material may be attached to the filter and used.

[0007]

Since the dripper pack of the present invention pours hot water directly into the pack, extraction is fast and aluminum is integrally attached to the bag type filter, so when pouring hot water, the mouth shape opens stably and inside the cup. When you take it out from the mouth, the knob part is attached around the mouth so that the pack lifts vertically and there is no coffee powder or hot water leaking from the mouth.
Since the filter and aluminum foil are integrated filters, the strength to hold the mouth shape and the whole shape when pouring hot water is generated.Also, the heat reflection of aluminum keeps the hands holding the pack inside the cup or inside the pack. Protecting from heat The aluminum film on the part that does not have holes when directly holding the pack protects from the coffee liquid. Since the knobs are provided on the front and back, the mouth can be flatly closed in one stroke by grasping the knobs by hand from the front and back, and the bag mouth filter is lifted at two positions symmetrical to the front and rear of the mouth so that the upper mouth is large inside the cup. Even a full-sized bag-type filter can be lifted vertically and taken out.
