Description

[Detailed Description of the Invention] The present invention relates to a simple permeable coffee pack that allows delicious coffee to be easily dispensed.

Traditionally, tea bags such as black tea or green tea have been available that are convenient to carry, making it easy to brew delicious black tea anywhere, but when it comes to coffee, the infused liquid is powdered Although so-called instant coffee exists, in order to make coffee with the original flavor rich in coffee beans, it is necessary to use the siphon method,
This method has disadvantages such as having to use a cumbersome method using some kind of equipment such as a drip method (cloth or paper drip method), and being subject to space limitations.

Therefore, this invention uses a method similar to the conventional paper drip method that is convenient to carry and can be used in any location.
To provide a simple permeable coffee pack that can easily contain coffee with the original rich flavor made from coffee beans.

The present invention provides an annular support member that has a certain shape-retaining force and can be folded into a flat shape at the opening edge of an outer bag made of a water-impermeable material with a drainage hole in the bottom. A protruding line and a groove for fitting are provided along the inner surfaces facing each other, and a filter paper bag containing finely granulated coffee beans is stored in the outer bag along the inner surface thereof, and the filter paper bag is fitted into the outer bag. This relates to a simple permeable coffee pack characterized in that the opening edge of the filter paper bag is sandwiched between the protrusions and the grooves of the wearer, and the two are fitted together. Embodiments of the present invention will be described in detail with reference to the drawings.

In the figure, 1 is a flexible outer bag formed into the required bag shape from a water-impermeable material such as a synthetic resin sheet or a certain waterproof paper. The drainage hole 2 is drilled.

Reference numeral 3 denotes a filter paper bag housed inside the outer bag 1 along its inner surface, and is made of Japanese paper or Japanese paper into which fibrous plastic has been made. Coffee beans 4 are stored.

Reference numeral 5 denotes an annular support member adhered or welded to the opening edge of the outer bag 1, and the annular support member 5 is made of thick flexible plastic or a flexible filament. The member has a certain shape-retaining force, that is, the strength is strong enough to hold one end of the member to form an annular opening as shown in Fig. 4, and maintain that state, and it is convenient to carry when not in use. In this way, the annular portion can be folded into a flat shape.

Further, 6 and 7 in the figure are protrusions and grooves for fitting provided along the inner surfaces facing each other when the annular support member 5 is folded into a flat shape, and as shown in FIG. By fitting the protrusions 6 and the grooves 7 with the opening edge of the filter paper bag 3 held between the two, both the openings of the outer bag 1 and the filter paper bag 3 are closed at the same time, and the inside of the filter paper bag 3 is closed. This is to maintain the freshness of the fine-grained coffee beans 4 stored in the bag, and to prevent the coffee beans 4 from spilling when carried.

In the present invention, in order to avoid the above structure, the annular support member 5 is provided with a protrusion 6 and a concave groove 7, and as described above, by fitting them together, the openings of the outer bag 1 and the filter paper bag 3 are simultaneously closed, and the product is removed. none,
To use, tear the packaging bag and take out the coffee pack of the present invention, open the openings of the outer bag 1 and the filter paper bag 3 as shown in FIG. Hold one end of the coffee cup with your finger and then pour boiling water over the fine coffee beans 4 stored in the filter paper bag 3 in the same way as in the conventional paper drip method. 1 serves as a support container in the conventional paper drip method, whereby hot water is allowed to pass through the fine coffee beans 4 for an appropriate period of time to infuse the coffee extract, and is filtered through the filter paper bag 3. The used coffee pack falls into the coffee cup through a drainage hole 2 made at the bottom of the outer bag 1 and is stored therein, and the used coffee pack is discarded by closing the opening again.

As explained in detail above, according to the present invention, the openings of the outer bag and the filter paper bag can be closed simultaneously and reliably by providing the protrusions and grooves on the opposing surfaces of the annular support member. Therefore, it is possible to reliably maintain the freshness of the finely ground coffee beans, and to effectively prevent the coffee beans from spilling when carried.
