The present invention relates to a food container that is dissolved in water and that can be extracted or reduced with steam and heated water. Examples of the above-mentioned foodstuffs may include herbal medicines including coffee, tea, chocolate, herbs, or other dehydrated or concentrated edible substances or milk, condensed milk, powdered milk, baby food, and the like.

Coffee may be a representative food among the above-mentioned foods, and is a favorite food of many people, and many people enjoy drinking it all over the world. One of the common methods of extracting and drinking coffee is to grind the roasted coffee beans and place them in an inverted triangular conical filter, and extract hot water by gravity under normal pressure. Is widely used.

An Italian inventor invented a delicious method of extracting a so-called espresso coffee, which is widely accepted and enjoyed by many people. It is a method of instant dissolving and dissolving coffee with high pressure steam and high temperature water. The extraction method is to grind the coffee into a silver powder, put it in a closed container that can withstand the pressure and extract it instantaneously with high pressure steam and hot water. In this case, undesired caffeine or coffee oil is left with the rest, and the aroma of coffee is strongly extracted.

However, the extraction method of the espresso coffee requires a very expensive and complicated machine, and because it takes a lot of hands, it is very inconvenient for general users, and a simple extraction method is to wrap the coffee in a sealed container such as a cartridge.

US patent US2968560 describes a cartridge having an internal filter forming two compartments and which is allowed to be extracted by a system that penetrates its upper and lower surfaces prior to extraction. The disadvantage of this cartridge type is that the thickness of the face requires the use of a relatively hazardous through system which does not readily realize perfect cleanliness during extraction and completion of extraction.

The cartridges of US patents US4136202 and US5948455 are intended to rupture preferentially under the influence of pressure. In order for the opening of the cartridge, which is a characteristic of this patent, to be accurately reproducible, the materials used must be very precisely processed, which increases the cost and complexity of using the cartridge.

US patent application US2002 / 0015768A1 shows an improvement over the above patents, which has a foamed layer at the bottom, which prevents backflow of the extract or residue. It is also a way to force the bottom to secure an outlet.

Above all, in the field of espresso-type coffee to be extracted under pressure, there are a number of reasons for using sealed containers for the extraction of favorite beverages: convenience in use due to the simplification of the extraction process, uniform quality control of the obtained coffee, and maintenance of hygienic extraction environment. Optimal coffee preservation and good reproducibility of extraction conditions and tastes exist. Of the various available sealed containers, only sealed containers which actually open under the influence of injected water and water vapor pressure or as a physical method satisfy the above requirements.

In addition, the main reason why these espresso coffee extraction methods and machines are still operated exclusively by specialists and not universalized can be attributed to the high cost of the extractors and the complexity of the extraction methods.

The sealing container 10 is composed of a body portion (20) surrounding the contents corresponding to the cup and a cover portion (30) which functions to block the contents wrapped in the body (20) from the outside. These two parts are firmly attached to and fixed to the jaw 22 which is attached to the end of the body 20.

The sealed object 10 is packaged with a desired object. The packaged contents are dissolved, extracted as water vapor and water injected through the orifice and discharged to the outside.

The sealed container 10 of the present invention is molded from a material having flexibility of oxygen and fluid impermeability, and enables the storage to be altered for a predetermined period of time while the contents are hermetically sealed.

One of the body 20 and the cover 30 is provided with an inlet 51 so that the orifice can be inserted, and the outlet 57 is provided on the opposite side so that the extract can be discharged. The injection port 51 is attached to a rigid blocking film 53 in the form of a film or sheet, but is ruptured by inserting an orifice capable of supplying steam and water when extracting the contents, and injecting high-pressure steam and heating water. It is designed to be.

The blocking film 53 attached to the injection hole 51 selects and attaches a film or sheet having a low air permeability. As the film or sheet having low air permeability, a film such as polyethylene, ethylene vinyl alcohol (EVOH), polyvinylidene fluoride (PVDC) or aluminum, or a sheet or a film of this multi-layer can be used. In order to strongly bond the sealing container 10 and the blocking film 53, the surface of the blocking film 53 may be attached using a solvent adhesive 73 or a hot melt adhesive 73. Adhesive 73 suitable for use and good is widely supplied on the market, and a separate description of the adhesive 73 will be omitted.

On the opposite side to which the inlet 51 is provided, there are many outlets 57 of small diameter. The discharge port 57 has a small diameter so that only the extract liquid is discharged without extracting the contents during or after extraction. The discharge port 57 has a diameter of 0.1 mm to 2.0 mm, preferably 0.2 mm to 1.0 mm. The outlets 57 are tightly adhered and closed by the blocking film 59, but when the contents are extracted, the blocking film 59 is removed, and when the hot water vapor and a predetermined pressure are transferred to the inside through the orifice, the extract liquid It is designed to be discharged under the outlet 57. The blocking film 59 serves to block external contact of the contents and oxygen and fluid, such as the blocking film 53 applied to the injection hole 51. As the material thereof, a film such as polyethylene, ethylene vinyl alcohol (EVOH), polyvinylidene fluoride (PVDC) or aluminum, or a sheet or a film of this multi-layer can be used.

Cover 30 is strongly attached to the jaw 22 of the body 20 is configured to support the overall shape in three dimensions and to keep the inside airtight to withstand the high-pressure steam injected from the outside during the extraction of the contents.

The sealed container 10 of the present invention is designed to be extracted under a predetermined pressure, and is composed of a body 20 and a cover 30 to package a material for extraction of a beverage, the diameter of the body 20 It has a sealed cylindrical, truncated cone or hemispherical yarn having a base R3 less than or equal to (R2).
The sealed container 10 can withstand a pressure of 20 atm, has a low air permeability and a softening point selected from materials of 100'C or more, and the outlet 57 is physically located at the start of the extraction process. It is characterized by its removal by means of a method or by opening only under forced rupture from the outside.

In addition, the sealed container 10 is opened only under predetermined conditions and the contents are extracted. In the case of the blocking film 53 on the injection hole 51 side, the blocking film 53 attached to the injection hole 51 is first ruptured by the insertion of an orifice (injector), and under the influence of the extraction heating water and the vapor pressure, the contents become water. Dissolved in steam and extracted. During or after extraction, a foam 55 may be attached to the inside of the inlet 51 or the front end of the outlet 57 so that the particles of the contents are not discharged to the outside. The foam and the like act as a valve 55, and the extract liquid is discharged, and the particles of the contents are not passed through.

The barrier film 59 is firmly attached to the discharge port 57 by an adhesive 73 and sealed. The blocking film 59 attached to the outlet 57 is made of a material having a low oxygen permeability to protect the contents for a predetermined period of time. The adhesive 73 is preferably odorless and does not affect food, such as solvent- or solvent-free hot melt (Hot-Melt). The blocking film 59 has a ring 75 so that it can be easily removed during use, and a hole 77 is drilled in the ring. The blocking film 59 may be attached to the 'L' on the attachment surface so that it can be easily removed by hand or machine. In the case of detachment by machine, an object that can be caught in the hole 77 of the ring 75 is inserted and detached mechanically. The adhesive 73 adheres to the blocking film 59 and falls off when the blocking film 59 is removed. The cover 30 is provided with a positioning groove 23 to accurately know the position of the ring or the injection hole 51 into which the orifice can be inserted.

After the barrier film 59 is physically removed, the extract liquid dissolved in the sealed container 10 is discharged out through the lower outlet 57. After extraction, the sealed container 10 can be easily removed from the extractor and the packaging remains while leaving a minimum of coffee grounds (extraction residue).

In addition to the method of physically detaching and removing the blocking film 59 of the discharge port 57 including the filter 71 from the sealed container 10 and by rupturing by the pressure of the vapor delivered through the orifice, the blocking film 59 is forcibly removed. Penetration or rupture may be used. It is a method of securing the outlet 57 of the extract by drilling the barrier membrane 59 with several small pins or needles arranged on the outlet 57 side of the sealed container 10 before extraction.

The sealed container 10 allows to withstand pressures of up to 15-19 atmospheres during the extraction process.

In the sealed container 10 of this invention, the food which melt | dissolves in water and can be extracted or reduced by steam and heating water can be packaged. Examples of foods are roast and ground coffee, but dehydrated or concentrated edible substances such as soluble coffee or coffee blended beverages, teas, chocolate, herbs, or other dehydrated or concentrated foods, flours, substitutes or Milk, condensed milk, powdered milk, baby food, and the like.

The sealed container 10 of the present invention is particularly suitable for the extraction of espresso coffee. The conditions for making delicious espresso coffee are: blending good coffee beans, good water at the right temperature, and extraction pressure and extraction time.

Coffee beans, which have been harvested, are in a state where the original flavor of the coffee beans is easily destroyed as we go through the coffee. If you leave it alone, the flavor can change little and last for years. However, the ground coffee powder tends to change flavor faster than roasted beans. A week after the roasted bean is in contact with the air, the ground coffee powder begins to lose its flavor after an hour and the boiled coffee in just a few minutes. Since ancient times, the Arabs have all begun to distribute, crush, and extract the problem within 30 minutes. The easiest and most effective way of conveying so far is to grind and extract fresh roasted beans just before extraction and drinking.

In order to store the ground coffee without rot for a long time, the ground coffee powder is tightly sealed to prevent contact with oxygen and moisture. The material of the container may be made of oxygen and fluid impermeable material, and at the same time, nitrogen gas may be mixed into the packaged contents to prevent the penetration of other gases and moisture.

In order to extract espresso coffee, generally 1 mm thick coffee powder is known to be suitable. For ground coffee, you need about 5-10grams to brew a cup. The apparent specific gravity of less compressed ground coffee is approximately 0.4-0.6 grams / cc. The sealed container 10 thus requires a volume of 5-20 cc in order to brew 1-2 cups of coffee.

The material that may be composed of the main part of the sealed container 10, namely the body 20 and the cover 30, may be made of plastic, for example low density polyethylene resin, high density polyethylene resin, polypropylene resin, polystyrene resin, ABS resin, poly Pure plastic materials such as carbonate resins, polyacetal resins, polyacrylic resins, and polyester resins use resins with a softening point of more than 100'C or aluminum sheets, aluminum castings, stainless foils, iron sheets or any By selecting one from a multilayer plastic and from a crowd of non-woven layers such as pulp mold or multilayer sheets such as cardboard / aluminum / plastic, plastic / metal foil or cardboard / plastic, the body 20 has a thickness of 60 μm to 2,000 μm, preferably 60 It can be used by molding to a thickness of μm to 1,000 μm and the cover to a thickness of 100 μm to 2,000 μm, preferably 100 μm to 1,000 μm.

The body 20 of the sealed container 10 need not necessarily be in the form of a plane. Cylindrical, truncated and hemispherical.

To the inlet 51 into which the orifice can be inserted, a foam 55 or a woven valve 55 is attached so that the orifice can act as a shutoff valve 55. Even if the valve 55 prevents the backflow of the extract liquid, and the valve 55, which is a woven fabric or foam having elasticity, is closed again to prevent the contents from flowing out when the orifice inserted after use is removed. Can be.

The opposite side of the inlet 51 is provided with a large number of outlets 57 of small diameter so as to facilitate the discharge of the extract after extraction of the contents. The outlet 57 should have a small aperture so that finely ground coffee powder is not discharged out during extraction. The aperture is at most 2 mm, preferably 0.7 mm, more preferably 0.5 mm and may be smaller than 0.1 if the extract can be discharged.

In order to prevent the contents from dispersing on the fluidized bed during the extraction and exiting with the extract, a woven or non-woven fabric composed of fibers with filtering as the main function may be additionally provided if necessary. . This may be referred to as filter 71, which layer of filter 71 is bonded or fused to the outlet 57 side. The filter 71 may have a density of 10 to 150 grams / m 2, preferably 20 to 60 grams / m 2. The filter 71 is positioned on the outlet 57 side to reduce the dispersion and discharge of insoluble particles or coffee grounds, and at the same time ensures homogeneous extraction.

In addition, when the extract is discharged, the filter 71 at the discharge port 57 side adsorbs coffee oil present in the coffee in addition to the filtering function to reduce the discharge of undesired unnecessary objects.

The sealed container 10 can vary in size depending on the volume of content to be prepared. It is desirable that the contents vary from 5 to 200 cc. The diameter of the sealed container 10 is preferably 20 ~ 50mm and the length of the container can be determined between 10 ~ 100mm.
