Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beverage extraction pack that encloses extraction raw materials such as coffee, black tea, and green tea inside the package and injects liquid from the top to extract the beverage.

0002

[Prior Art] Traditionally, extraction ingredients such as coffee, black tea, and green tea are sealed in airtight packs for long-term storage.
It is known that when in use, hot water is poured from above to extract the beverage. For example, in Japanese Patent Application Laid-Open No. 59-51065, a double-layered pack 1 is used as shown in FIGS. 10 and 11, and a synthetic resin pouring spout 3 is provided above the outer bag 2. It is disclosed that hot water injected through a nozzle passes through an extraction raw material 5 such as coffee stored in an internal filtration part 4, is extracted as a beverage, and is discharged from a discharge part 6 opening at the bottom of the bag body 2. ing.

0003

[Problems to be Solved by the Invention] However, in the above-mentioned conventional example, it is necessary to insert the thin nozzle into the spout 3 reliably, which requires positioning accuracy, and furthermore, there is a gap between the nozzle and the spout 3. If compressed air is supplied for the purpose of hastening extraction after pouring, there is a risk that air will leak from the gaps and the reduction in extraction time will not be as significant.

An object of the present invention is to provide a beverage extraction pack that solves the above-mentioned problems, can be used without requiring highly accurate positioning of the nozzle, and has less leakage of liquid or gas from around the nozzle during extraction. It is in.

[0005]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the beverage extraction pack according to the present invention is a sealed pack consisting of a bag body inside which a filtration section containing extraction raw materials is attached. An elastic member made of synthetic resin or the like is attached to the upper part of the bag body, and a nozzle is pierced through the elastic member so that liquid can be injected into the inside.

[0006]

[Operation] In the beverage extraction pack having the above-described structure, a nozzle can be pierced from any part of the elastic member at the top of the bag, and liquid is injected into the bag to extract the beverage.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained in detail based on the embodiments shown in FIGS. 1 to 9. FIG. 1 is a front view of the pack 10,
FIG. 2 is a plan view, and FIG. 3 is a longitudinal sectional view. In the pack 10, a bag 1 is placed inside a rectangular bag 11 made of, for example, a synthetic resin sheet that is airtight against water and air.
A filter sheet 12 made of a non-woven fabric is provided across the filter sheet 1, and an extraction raw material 13, which is obtained by grinding roasted coffee beans, for example, is stored inside the filter sheet 12. The filter sheet 12 has a V-shaped or U-shaped vertical section, and both ends 12a
, 12b are bonded to the inside of the bag 11 by, for example, heat welding. An elastic member 14 made of, for example, synthetic resin foam is attached to the upper part of the bag 11. Further, the discharge section 15 at the lower part of the bag body 11 is sealed with an adhesive that is thermoplastic and has the property of being peeled off by hot water.

Further, the modified example shown in FIGS. 4 and 5 corresponds to the pack 10 shown in FIGS. 1 and 3, and the discharge part 15 at the lower end of the bag body 11 is folded back, so that the lower end is folded back when in use. The package is opened by cutting it with a cutter or the like.

FIG. 6 shows the main parts of a beverage brewing device 20 that uses this pack 10, including a pair of gripping members 21a and 21b for gripping the pack 10, and a needle-shaped syringe for supplying hot water into the pack 10. Hot water supply section 2 with nozzle 22
It has 3.

In use, the gripping members 21a and 21b are
After narrowing the gap and gripping the pack 10, open the hot water supply section 2.
3, the nozzle 22 punctures the elastic member 14 at the upper part of the bag 11, and the nozzle 22 is further inserted into the pack 10 as shown in FIG. 7 and stopped. In this case, the upper surface of the elastic member 14 has a relatively large area, and the nozzle 22 can be inserted into any desired location on the elastic member 14. Further, after the nozzle 22 is punctured, the periphery of the nozzle 22 is sealed by the elasticity of the elastic member 14.

Then, hot water is poured into the pack 10 from the hot water supply section 23 through the nozzle 22, and then air with increased pressure is injected.The hot water moves the extraction raw material 13 and the filter sheet 12 at high speed while being under pressure. The adhesive in the lower discharge part 15 is peeled off using heat and pressure to form the bag body 1.
The lower end of the cup 1 is opened, and the coffee liquid is discharged from the discharge part 15 into, for example, a cup 24 placed below. Note that, as shown in FIGS. 4 and 5, when the bag 11 is folded back, it goes without saying that it is necessary to open the discharge part 15 with a cutter or the like before pouring hot water.

In FIG. 8, a cutting blade 25 is provided in an annular shape at the base of the nozzle 22 of the hot water supply section 23. As shown in FIG. Therefore, when the nozzle 22 is inserted into the elastic member 4, the cutting blade 25 also bites into the elastic member 14 and covers the periphery of the nozzle 22, thereby further reducing leakage.

FIG. 9 shows still another embodiment, in which a pushing part 26 is provided inside the cutting blade 25 and has a tapered part opposite to the inclined part of the cutting blade 25a. When the nozzle 22 is inserted into the elastic member 14, the pushing part 26 is inserted into the elastic member 14.
This will reduce leakage of liquid and substrate from this area.

Although the elastic member 14 has a hexagonal shape in the embodiment, this shape is not limited to the embodiment.

[0015]

Effects of the Invention As explained above, since the beverage extraction pack according to the present invention is provided with an elastic member on the upper part, the nozzle can be punctured into this elastic member, and even if the nozzle is punctured, the surrounding area of the nozzle is No liquid or gas will leak from the In addition, since there are no significant restrictions on the size of the nozzle, a thick nozzle can be used, and the amount of poured metal per hour can be increased and the extraction time can be shortened.
