Abstract

PURPOSE:To provide a dripping pack which is so composed that coffee powder and hot water may not leak out through an opening part when the pack is taken out from a cup and that its deformation to the hot water can be prevented. CONSTITUTION:A bag-shaped filter 1 wherein its inside is filled with coffee powder and an opening part 4 therefor is temporarily stuck at an adhesive part 8 and is sealed, has a number of through-holes thereon, which filter is integrated with aluminums foil 2. This bag-shaped filter is used by being put within a cup 9, and hot water is directly poured into a pack through a pouring surface 6, and thus the extraction of essense from the coffee powder is quickened. This filter also has a suspending part 5 with which the pack is vertically lifted so that the coffee powder and the hot water may not leak out through the opening 4, when taken out from the cup 9. Since the whole of the filter 1 is reinforced with aluminum, its deformation to the hot water can be prevented.

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, and 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 drawback that the filter softened and deformed 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. Since the bag type used for pouring is in the cup, it has a drawback that the drip action is small and the taste is defective. There was also a drawback that it was hot and difficult to hold by hand after extracting the filter pack. Further, the conventional filter is fibrous, and even if it is colored, the luster and color of the colored color are not clear because the material of the filter surface has shades.

[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 is provided with a passageway for hot water to pass through.The filter blocks this passageway with this filter. A dripper pack that is used by putting coffee powder into it and forming a bag type coffee pack with a filter that integrates aluminum foil. 2. The bag-type filter is an inverted conical shape with a thin lower side and a wider upper mouth side.The upper mouth has a mouth shape with a high back side and a low front side. A dripper pack that is filled, closed at the mouth and temporarily adhered.

[0005]

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

[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 and the synthetic resin film prevent the hand from being soiled with coffee liquid. Aluminum reflects the heat when held by hand and the heat inside the pack goes out of the pack or the rise of heat in the cup is blocked by the aluminum pack body and the hands located at the top are protected from the heat and the aluminum foil is extracted It also keeps the inside of the pack warm. Also, the aluminum foil with a thickness of about 15 microns is used to reinforce the filter so that the weight of the hot water and the hardness of the aluminum do not change due to this property. It prevents deformation of the mouth shape and overall shape of the bag type filter in the cup due to pouring and makes it easy to pour hot water.When the filter is covered with aluminum foil, the silver color and light of the aluminum foil Also resulting effect of adding to the filter surface. 1. In a simple coffee extractor, the filter and aluminum foil surfaces are attached together, and the aluminum foil is provided with a passageway for hot water to pass through.The filter blocks this passageway with this filter. A dripper pack that is used by putting coffee powder into it and forming a bag type coffee pack with a filter that integrates aluminum foil. 2. The bag-type filter is an inverted conical shape with a thin lower side and a wider upper mouth side.The upper mouth has a mouth shape with a high back side and a low front side. A dripper pack that is filled, closed at the mouth and temporarily adhered. The bag-type filter of the present invention is an inverted conical type filter having a narrow lower side and a wider upper mouth side. The lower part is placed on the bottom of the cup and the upper mouth side is tilted in one direction inside the mouth part of the cup. The tubular bag-shaped filter inside the cup stabilizes in the front, rear, left and right by setting it close to the mouth of the cup and the upper mouth is cut horizontally to the cup mouth when set in the cup. It has a shape that makes it easy to pour hot water into the bag. Further, the bag-type filter has a capacity of one-third of the capacity of the cup, and although it is a system of setting in the cup, it is possible to drip close to 100% in the cup. When the aluminum foil is integrally attached to the filter and attached, the filter is reinforced by the hardness of the aluminum foil and the shape of the bag type filter can be freely formed in the cup, and the frame is attached to the filter and set in the cup as in the past. There is no need. Also, the front and back surfaces of the aluminum foil may be further covered with a synthetic resin film. The bottom of the bag-type filter is fixed on the bottom of the cup, and the bottom is narrow and the upper mouth is large.
A metal foil or heat-reflecting material may be attached to the filter and used. Since the knob is located close to one end of the mouth of the bag-type filter, when you hold the coffee pack by hand and take it out of the cup, the position of your hand will be outside the cup or the pack, and you will be raised from inside the cup or inside the pack. You no longer receive heat directly. Further, if the mouth portion is shaped such that one side is high and the other side is low, the inner wall surface on the high side of the mouth portion can be used as a pouring surface (6) when pouring hot water into the pack, which facilitates pouring hot water.

[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 that when pouring hot water, the mouth shape opens stably and the setting mechanism is set. It has a simple structure that does not require Since the filter and aluminum foil are integrated, strength to hold the mouth shape and the whole shape when pouring hot water is generated in the cup.Also, heat reflection of aluminum heats the hands holding the pack in the cup or Protecting from the heat inside the pack Aluminum foil and synthetic resin film on the part that does not have holes on the hands that directly hold the pack protect from the coffee liquid. Since the knob part is provided in the same shape as the mouth part, the mouth part can be closed flat in one stroke by pinching the knob part from the left and right sides by hand. Since it is an inverted conical bag type pack, hot water runs out in the lower part of the pack in the cup and a drip action can be obtained even with a bag type dripper pack placed at the bottom of the cup. Coffee powder is deposited downwards and the hot water runs out quickly. Since the filter surface is covered with aluminum foil or a colored synthetic resin film, it is possible to add vivid colors and gloss to the filter surface.
