[Technical field to which the invention belongs]

The present invention relates to a sealed container for beverage preparation, in which beverage components such as regular coffee, black tea, and powdered juice can be sealed one by one, and a beverage can be made with a dedicated bending machine or the like. There is no beverage left, it is more hygienic, it can be made compact, and maintenance of the bending machine etc. is easy.

【0002】

[Conventional technology]

Conventionally, beverage ingredients such as powders such as regular coffee, tea and powdered juice, pastes such as soups, and liquids such as concentrated juices are placed in a sealed container for each dose, and this is placed in a dedicated bending machine or cup. It is provided as a beverage by extracting, dissolving, and mixing with hot or cold water using a bender or the like, and various types of sealed containers are used.

【0003】

Examples of containers for sealing such beverage components include bag-shaped packs described in JP-A-59-51065 and JP-A-4-142266, and in the case of regular coffee, the figure is shown in the figure. As shown in 5 and FIG. 6, in packs 1 and 2, a filter material 4 such as a non-woven fabric is placed inside the sealing sheet material 3 and coffee powder 5 is put into the pack to form a bag. , An injection port 6 for hot water or the like is attached to the upper end portion, or a puncture sheet portion 7 is provided.

【0004】

Then, when extracting coffee, packs 1 and 2 are attached to a beverage brewing device such as a bending machine, a nozzle 8 is inserted into the injection port 6 and the puncture sheet 7 to pour boiling water, and air with further pressure is applied. Inject and receive coffee in cup 9 below packs 1 and 2.

【0005】

Further, in the sealed cartridge described in JP-A-4-236921, as shown in FIG. 7, the cartridge 10 is formed of aluminum or plastic in a truncated cone shape or the like, and the filter 12 is arranged on the lower surface 11. Coffee powder 5 is placed in the upper part of the filter 12 to seal the upper surface 13 and the lower surface 11, while the lower surface 11 is torn at a predetermined pressure.

【0006】

Then, when coffee is extracted, it is introduced into a dedicated extraction device, the water injector 14 is inserted through the upper surface 13, hot water is poured from a plurality of orifices, moistened, and then the lower surface 11 is deformed by water pressure. Let it split and receive coffee in a cup through the spout 15 formed in the space below.

【0007】

In such bag-shaped packs 1 and 2 and the sealed cartridge 10, when extracting coffee, a nozzle 8 for injecting boiling water and a water injector 14 are inserted into a storage portion containing coffee powder 5. Therefore, the beverage component adheres to the nozzle 8 and the water injector 14, or the beverage component adheres to the injection port 15 of the extraction device, which adversely affects the next extraction and deteriorates the aroma and taste.

【0008】

On the other hand, as a sealed container in which the nozzle for injecting boiling water does not come into contact with beverage components such as coffee powder, for example, there is a tubular capsule described in JP-A-6-315349, which is shown in FIG. As shown, coffee powder 5 is placed in the tubular capsule body 21 of the capsule 20 by sandwiching the upper and lower filters 22, and the upper and lower parts of the capsule body 21 are sealed with a sealing sheet 23.

【0009】

Then, when coffee is extracted, the hot water injection nozzle 24 of the brewing device is inserted into the capsule body 21 from the upper sealing sheet 23 to inject hot water, and the receiving port 25 inserted into the capsule body 21 from the lower sealing sheet 23 is used. Guide the coffee to the outside and receive it in cup 9.

【0010】

In such a tubular capsule 20, the boiling water injection nozzle 24 does not come into direct contact with the beverage component such as coffee powder 5, but it is difficult for the boiling water to evenly distribute to the beverage component, and when trying to distribute the capsule The volume of the upper part of the main body 21 must be increased, and the capsule 20 cannot be made compact.

【0011】

In addition, it is necessary to sandwich beverage components such as coffee powder 5 with two upper and lower filters 22, and the upper and lower parts of the capsule body 21 must be sealed with a sealing sheet 23. The manufacturing and filling process of the product becomes complicated.

【0012】

Further, since the receiving port 25 is inserted into the lower sealing sheet 23 to take out the coffee and guided to the outside, the oil content of the coffee adheres to the receiving port 25, and maintenance such as a bending machine for removing this by chemical cleaning or the like is required.

【0013】

On the other hand, in the rectangular box-shaped sealed container described in JP-A-4-224715, as shown in FIG. 9, a beverage component such as coffee powder 5 is placed in the main body 31 which is rectangular box-shaped and has an open bottom surface. In addition to providing a compartment 32 for storage, a passage 33 is formed on the outside of the three sides around the compartment 32, and a hot water inlet 34 communicating with the passage 33 is provided on the top surface of the compartment 32 and the passage 33. A large number of slit-shaped injection ports 35 are formed at the lower end of the side wall between the two walls, a filter 36 is provided below the top surface of the partition chamber 32, and the space between the filter 36 and the top surface is opened as an extraction flow path 37 on the lower surface. The sealed container 30 is configured by communicating with the spout 38 and covering the entire lower surface with a film-like sealing material 39.

【0014】

Then, when extracting coffee, a sealed container 30 is attached to a dedicated beverage preparation device, pierced from the top surface, a nozzle 40 for boiling water is inserted, and the coffee is injected into the passage 33. The coffee powder 5 in the compartment 32 is sprayed from the slit-shaped injection port 35, and turbulent flow is generated to allow hot water to flow from the bottom to the top, and the extraction flow path 37 between the coffee powder and the top surface is passed through the filter 36. The coffee collected in step 1 is received by an external cup through the spout 38 opened with a piercing tool.

【0015】

As a result, the size is reduced, the number of sealed parts is reduced, and the manufacturing / filling process of the sealed container 30 is simplified.

【0016】

[Problems to be Solved by the Invention]

However, in such a sealed container 30, it is necessary to open the spout covered with the sealing material 39 with a piercing tool, which complicates the mechanism, and in particular, it is retracted after opening and does not come into contact with coffee or the like. If this is done, the mechanism will become more complicated and the bending machine will become larger, but if the piercing tool is not sufficiently retracted and is near the spout 38, coffee oil will adhere and chemicals will be attached. There is a problem that maintenance such as cleaning is required.

【0017】

In addition, since boiling water for extracting coffee flows from the bottom to the top from the injection port 35 at the lower end of the compartment 32 toward the extraction flow path 37 on the top surface and is filtered by the filter 36, coffee or the like is contained in the container 30. There is also a problem that the extract of coffee is likely to remain, which makes coffee grounds and the like easily spoil.

【0018】

Further, as a performance required for such a sealed container, it is necessary to have a structure in which coffee powder put in a compartment or the like is discharged to the inlet side or the spout side and is not mixed in the extract.

【0019】

The present invention has been made to solve the problems of the prior art, and the liquid medium can be spread over the entire beverage component to enable uniform extraction, and no liquid remains in the container after use, which is more hygienic.
