Sealed Container for Liquid Food Extraction

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 common method of extracting and drinking coffee is to grind the roasted coffee beans and place them in an inverted triangular conical filter, and to extract hot water by gravity under normal pressure. The method is widely used.

An Italian designer devised a delicious way of extracting a so-called espresso coffee, which was widely accepted and enjoyed by many people in Korea. 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 high silver powder, put it in a closed container 10 that can withstand the pressure and extract it instantaneously with high pressure steam and high temperature 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 the hands are very inconvenient for the general user, so that the simple extraction by packing the coffee in a sealed container such as a cartridge has been attempted;

US patent US2968560 (GB938617) describes a cartridge that has an internal filter forming two compartments and 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 (CH605293) 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.

Applicant's application 10-2002-0008273 proposed a sealed container of cylindrical or frustoconical shape. It is possible to assemble and reuse.

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. Optimum coffee preservation and extraction conditions and good reproducibility of taste exist. Of the various available sealed containers, only sealed containers which are actually opened under the influence of injected water and water vapor pressure or by physical means 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 sealed container of the present invention is characterized by an outlet provided in the lower part of the container, a barrier film that blocks the outlet, and an opening system of the barrier film.

The advantage of the extraction system using the sealed container of the present invention is that anyone can easily and easily extract various desired extracts, including espresso coffee, and can make the sealed container at a low price, and the machine for extracting the contents thereof, Unlike conventional multi-million won professional machines, it can be produced at a very simple and low price, and if you pack the uniform coffee in a certain amount and extract it under the same temperature and pressure and the same time, it will always have a constant taste and aroma. It has the advantage of reproducibility. The sealed container and the extraction system of the present invention has been completed to devise the design of the sealing container for espresso coffee extraction of the present invention in order to be conveniently used in homes, offices, businesses and vending machines.

Coffee is one of the favorite foods and is enjoyed by many people around the world. One common method of extracting and drinking coffee is to grind the roasted coffee beans, place them on a filter of reverse triangular cone shape, and extract the hot water by gravity with a coffee drip at normal pressure. have.

An Italian inventor devised a delicious way of extracting a so-called espresso. It is widely accepted, and this espresso coffee is enjoying explosive popularity in Korea and enjoyed by many people. It is a method of instant dissolving and dissolving coffee with high pressure steam and high temperature water. The specific method of extraction is to grind the coffee finely, put it in a closed container 10 capable of withstanding the pressure and extract it instantaneously with steam of about 15 atmospheres and hot water of about 88 ° C to 95 ° C. In this case, undesired caffeine or coffee oil is left with the rest, and the aroma of coffee is strongly extracted.

However, since the espresso coffee is very expensive and requires complicated machines and requires a lot of hands, it is inconvenient for general users, so it is tried to simply extract coffee by packing it in a container such as a cartridge.

U.S. Patent US2968560 (GB938617) describes a cartridge having an internal filter forming two compartments, which is allowed to be extracted by a system penetrating its upper and lower surfaces prior to extraction. The disadvantage of this cartridge type is that due to the thickness of the face, it does not easily realize perfect cleanliness during extraction and completion of extraction and requires the use of a relatively dangerous through-system.

The cartridges of US patents US4136202 (CH605293) and US5948455 are intended to rupture preferentially under the influence of pressure. This has the disadvantage of increasing the cost and complexity of the use of the cartridges, since the materials used must be processed very precisely in order for the cartridge's opening to be accurate and reproducible.

According to US patent application US2002 0015768A1, the above-described patent is improved, and has a foamed layer on top. The needle is inserted into the upper part of the container to blow out water and steam to extract the contents, and the nonwoven fabric or plastic foam attached to the inside of the container serves as a backflow check valve 55 to prevent backflow of the extract. However, there is also a disadvantage that must be secured outlet.

Applicant's application 20-2002-0008273 proposes a cylindrical or truncated cone container. It is assembleable and reusable.

Above all, the use of sealed containers for the preparation of extracts in the field of espresso coffee and other extractable foods extracted under pressure has a number of reasons: convenience in use, hygiene, optimal content preservation, uniformity of the foods obtained. Good reproducibility of quality control and extraction conditions exists. Of the many available sealed containers or cartridges, only sealed containers which are actually opened by physical force satisfy the above requirements. Seal containers of this kind are characterized by their opening and extraction systems.

In addition, despite the excellent taste and aroma of espresso coffee, the main reason why the coffee extraction method and the machine are operated exclusively by experts and not universalized can be attributed to the fact that the extractor is expensive and the extraction method is complicated.

There are various reasons and advantages in applying the sealed container 10 to the present invention. To list the reasons;

The first is simple and easy extraction. Even if you are not an expert, anyone who extracts the espresso coffee or water soluble beverage with the container 10 of the present invention with a predetermined extractor immediately extracts an excellent espresso coffee or beverage by simply operating the extractor operation switch of the set condition. You can drink it. This easy extraction and dissemination of inexpensive extractors, in particular, has the advantage that it can contribute to the popularization of espresso coffee.

The second is reproducibility, which means that anyone can extract the same taste. This can be achieved by packaging the same contents in the same package and weighing them in the same machine and conditions.

Third, the contents are easy to store and manage. It is packaged individually in a sealed container of one or two cups of beverage extraction capacity, so there is no contact with air or oxygen, and it is easier to manage deterioration due to long-term storage than when the contents are used after being crushed and opened.

Fourth, it is more economical to use the container 10 of the present invention. It is characterized by the fact that the extraction machine using this container is simple in its required function, and in particular, it is possible to produce and supply at a lower price than the existing espresso coffee extractor, which has millions of won, and thus has a high possibility of expanding the base.

Fifth, since there is no need to touch or open the contents every time, each container has to be cleaned before or after use, whether it is a container or an extractor. Therefore, it is more hygienic.

As described above, the sealed container 10 of the present invention can be manufactured at a low price due to its simple structure, and is required as a container for extracting a beverage, especially a water-soluble food extracted under a pressure of 1 to 15 atmospheres. Since the various conditions can be satisfied, the above-mentioned various problems can be solved and can be widely used. The present invention, by hygienically packing the contents in a sealed container 10, in particular, anyone can easily extract the espresso coffee, to provide an environment that can be distributed in large quantities by producing the packaging coffee and the extractor at a low price There is a characteristic to give.

The sealing container 10 of the present invention 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 container 10 is packaged with an object of interest. The packaged contents are dissolved, extracted as water vapor and water injected through the orifice and discharged to the outside.

The container 10 of the present invention is a sealed container 10 formed of a material having flexibility of oxygen and fluid impermeability, so that the contents can be kept free of deterioration for a predetermined period of time in a hermetic state. give.

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 closed by attaching a hard 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, blowing high pressure steam and heating water. It is designed to be placed.

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 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.

Low and softening point (Softening Point) is configured by selecting from the material of more than 100 ℃ discharge port 57 is characterized by being removed only by the physical method at the beginning of the extraction process or only under forced rupture from the outside.

The sealed container 10 of the present application 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 barrier film 59 may be attached to the attachment surface by the letter "L" 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 59 is physically removed, the extract liquid dissolved in the interior of the vessel 10 is discharged out through the outlet 57 of the lower portion. 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).

Forcibly penetrates the barrier membrane 59 in addition to the method of physically removing the barrier membrane 59 of the outlet 57 including the filter 71 from the vessel 10 and rupturing it by the pressure of steam delivered through the orifice. It can be used to make or rupture. 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 a pressure of up to 15 to 19 atm during the extraction process.

In the sealed container 10 of the present invention, a food product that can be dissolved in water and extractable or reduced by steam and heated water can be packaged. Roast and ground coffee are preferred as examples of the above-mentioned foods, but also herbal medicines including soluble coffee or coffee mixed drinks, tea, chocolate, herbs, or other dehydrated or concentrated edible substances, flour , Substitute or milk, condensed milk, powdered milk, baby food, and the like.

The 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.

It is generally known that 1 mm thick coffee powder is suitable for extracting espresso coffee. For ground coffee, you need about 5-10grams to brew a cup. The apparent specific gravity of the less compressed ground coffee is approximately 0.4-0.6 grams / cc. Thus, the sealed container 10 requires 5 to 20 cc of internal volume to brew 1 to 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 multilayers. By selecting one from plastic and a multitude of non-woven layers such as pulp mold or multi-layered 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 μm. The cover may be molded to a thickness of ˜1,000 μm and the cover may be molded 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 of the present invention does not necessarily have to 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, even when the orifice inserted after use is removed, the valve 55, which is a woven fabric or foam having elasticity, is anchored again to prevent the contents from flowing out. 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 may be up to 2 mm, preferably 0.7 mm, more preferably 0.5 mm and may be smaller than 0.1 mm 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 outlet 57 side adsorbs coffee oil present in the coffee in addition to the filtering function, thereby reducing the amount of undesired waste.

The sealed container 10 of the present invention may vary in size depending on the volume of the content to be prepared. It is desirable that the contents vary from 5 to 200 cc.
