Description

[Detailed explanation of the invention] [Industrial application field] This invention relates to a double-sealed container, and more specifically, it is a container in which raw material packs, which are separately placed in a raw material pack enclosure chamber, are immersed in hot water for drinking. This invention relates to a double-sealed container that can be extracted and drunk as is.

[Prior Art] In order to drink freshly brewed coffee, a device such as a siphon, percolator, or espresso machine is used. All of these instruments are made of glass, easily breakable, and have poor portability. On the other hand, coffee brewed in factories and packaged in cans or paper bags has become popular, but the taste is uniform and the delicate flavor of the coffee is diluted, making it unsatisfactory for coffee connoisseurs.

In order to eliminate such drawbacks,
As described in Japanese Patent No. 46630, it has been proposed that ground coffee powder, sufficient for one person, is placed in a container with a permeable hole in the bottom and enclosed in filter paper.

[Problems that the invention aims to solve] The above-mentioned simple drip-type coffee brewer can only be used in places where hot water is available, such as at home or at work, and it can be purchased from a vending machine and brewed on the spot. It is not drinkable.

As a solution to these shortcomings, Jikosho
As described in Publication No. 57-45936, an extract liquid receiving cup that receives the extract liquid and is fitted with this cup,
A through hole is made in the bottom, and the extract of ground coffee beans, etc., sealed inside with filter paper, is placed in an independent part with a partition plate, and the extract is poured onto this partition plate, and the opening is sealed. There is a configuration in which a hole is opened in the diaphragm using an aperture rod attached to the diaphragm, and the extract in the cup is permeated through the extract into the extract receiving cup. However, the disadvantage is that the structure is complicated and expensive.

[Purpose of the invention] In order to eliminate the above-mentioned drawbacks, this invention was designed to completely separate the extraction ingredients such as coffee and a cup of hot water in the same container, and cut the partition to extract the water when drinking. To provide a double-sealed container that can be sold in a vending machine.

[Means for Solving the Problems] In order to achieve the above object, the double sealed container of this invention has a stepped part formed on the lower inner circumferential surface of the container with one end open, and has a waterproof structure inside the container. A bulkhead partition plate is attached watertightly along the upper surface of the stepped portion to form a raw material pack enclosing chamber in which a raw material pack in which the raw material for extraction is packaged with a membrane member is enclosed between the bottom plate and the opening of the container. A diaphragm opening member is attached to the rim and has a cutting edge long enough to reach into the recess of the diaphragm by engaging a locking edge with the end edge bent into a square shape. A liquid storage chamber containing a liquid such as the like is provided, and the locking edge and the upper outer circumferential surface of the container are sealed with a seal.

[Embodiment of the invention] As shown in Figures 1a to 1c, the double sealed container A of this invention is made of a non-ventilated, non-permeable material such as aluminum foil or synthetic resin film made of aluminum or synthetic paper sheets. After placing the prepared partition plate 6 into the container 1, a raw material pack a containing extraction raw materials such as instant coffee, sugar, powdered milk, etc., wrapped in the over member 14, is sealed with nitrogen gas to prevent oxidation of the raw materials. It is attached along the upper surface of a stepped portion 1A provided on the lower inner circumferential surface of the container 1 so as to stop the container 1, and a raw material pack filling chamber 5 is formed between the partition plate 6 and the bottom plate 2, and is in contact with the outer periphery of the container 1. The periphery of the partition plate opening member 7, which also serves as a lid, is bent outward to form a locking edge 8.
A triangular cutting edge 9 is formed on the lower surface of the partition plate 6 so that when the locking edge 8 is locked to the opening edge 3, the length does not reach the bottom of the recess 6b of the partition plate from the opening edge of the partition plate 6. The partition plate opening member 7 is installed by inserting the opening edge 3 into the locking edge 8. Water b is poured into the liquid storage chamber 4 between the partition plate 6 and the opening edge 3. As shown in FIG. 1a and FIG. 2a, the outer circumferential surface of the locking edge 8 of the partition opening member 7 and the upper outer circumferential surface 11 of the container 1
Water leakage prevention seal 10 with peeling piece 12 between
It is heat-pressed. Incidentally, as shown in FIG.
3 may be installed. Note that the reference numeral 15 in the figure is a float knob connected to the raw material pack a.

[Operation of the invention] The double sealed container A of this invention is constructed as described above, and the container itself is placed in a heat storage and heated to heat the water b in the liquid storage chamber 4 to 70 to 90 degrees. Keep it and sell it.

The purchaser peels off the water leakage prevention seal 10 using the peeling piece 12 as shown in FIG. 2b from the state shown in FIGS. 1a and 2a, and then removes the water leakage prevention seal 10 from the state shown in FIGS. As shown in a to c, by holding the locking edge 8 and rotating the container 1, the cutting blade 9 rotates and cuts into the recess 6b.
While cutting the periphery of the partition plate 6 from the inside, the partition plate 6 is rotated through 360° and the process shown in FIGS. 2b and 3c and 3b and c is performed, leaving only the recess 6b. The hot water in the liquid storage chamber 4 begins to flow into the raw material pack enclosure chamber 5 at the start of cutting due to escape from the first recess, but thereafter, as shown in FIG. Since a moves from the raw material pack enclosure chamber 5 to the liquid storage chamber 4, the float knob 15
By holding the container 1 and shaking it up and down, the container 1 with a part of the partition plate 6 attached will be bent upward as shown in the figure, and coffee liquid etc. can be efficiently extracted from the raw material pack a.

[Effects of the invention] As described above, this invention forms a stepped portion 1A on the inner peripheral surface of the lower part of the container 1 which is open at one end, and installs the waterproof partition plate 6 inside the container 1 in a watertight manner. A raw material pack enclosing chamber 5 is formed between the stepped portion 1A and the bottom plate 2, in which a raw material pack a in which the raw material for extraction is packaged with the over member 14 is sealed, and a Locking edge 8 whose end edge is bent into a square shape
A diaphragm opening member 7 having a cutting blade 9 long enough to reach into the recess 6b of the diaphragm 6 is attached, and a liquid such as hot water is poured above the diaphragm 6 of the container 1. Since the liquid storage chamber 4 is provided and the locking edge 8 and the upper outer circumferential surface 11 of the container 1 are sealed with the seal 10, the container as a whole is made up of one container, which is easy to handle and allows for easy handling of raw materials during use. Since it does not spill outside and has a simple structure, material costs, processing costs, etc. are low, and it can be implemented at low cost. Therefore, if this invention is used as a coffee container, you can drink regular coffee that has a much better taste and flavor than commercially available canned coffee, has lower running and operation costs, and can be made with less sweetness. If you like sweets, you can add sugar, so you can add sweeteners or milk to your desired sweetness and taste compared to commercially available canned coffee, which is suitable for everyone.You can also use it as a tea pack, especially In this invention, the cutting edge 9 of the partition plate opening member 7 serves as a stirrer, so there is no need to attach a stirrer, which reduces costs, and the upper edge of the partition plate opening member 7 is formed in a square shape. The locking edge 8 is attached to the opening edge 3 of the container 1.
When the member 7 is rotated, the locking edge 8 serves as a rotation guide, so that the cutting blade 9 can cut the partition plate 6 beautifully and easily.
