 Disclosure of the invention

 Problems to be solved by the invention

[0005] Here, there are two important points in the extraction by the beverage extraction bag.

[0006] First, when hot water is poured into a beverage extraction bag, the nod body rises due to the gas generated from the beverage powder being filled in the bag body. This phenomenon is particularly noticeable in ground coffee beans. If the noggling body floats up, it penetrates into the hot water bag body and the amount of beverage powder extracted decreases. Therefore, it is necessary to immerse the bag body in hot water.

[0007] Secondly, if the water in the bag body containing a large amount of extract is not discharged outside the bag body, the beverage powder cannot be extracted to a sufficiently high concentration. Therefore, the liquid inside and outside the bag body It is necessary to increase and decrease the body.

 [0008] However, since the beverage extraction bag of Patent Document 1 has low string rigidity, the bag body cannot be immersed. Also, the bag body cannot be swayed well in hot water due to the resistance of water.

 [0009] Since the beverage extraction knob of Patent Document 2 is provided so as to penetrate the inside of the force knob body having rigidity in the thin pipe, even if an attempt is made to crush the bag body using the thin pipe, The thin pipes are changed to beverage powder or the bottom and cannot be crushed. Therefore, it is not possible to extract the liquid sufficiently deeply with little or no liquid in and out of the nod body. In addition, the fragrant fragrance generated by the powder power of the beverage is discharged to the outside through the thin pipe.

 [0010] Therefore, an object of the present invention is to provide a beverage extraction bag capable of extracting beverage powder in the bag body sufficiently deeply.

 Means for solving the problem

 In order to achieve the above object, the present invention has a bag body made of a filter material and a synthetic resin stick fixed to the nod body, and the stick is on the surface of the nod body. A beverage extraction nog characterized by being fixed and having a rigidity capable of crushing the bag body to such an extent that the three-dimensional shape of the bag body is deformed.

 [0012] In order to extract a beverage from this beverage extraction bag, first, a bag body of a filter material in which beverage powder is sealed is immersed in hot water, and a stick provided on the surface of the nod body is used to extract the beverage. The beverage in the dog body can be extracted by repeating the operation of pressing the dog body into hot water and the operation of lifting the dog body.

 [0013] At this time, since the stick has rigidity, the nod body can be immersed and crushed. By immersing the bag body in hot water, it can penetrate into the hot water S bag body and improve the extraction amount. In addition, it is possible to dissolve the hot gas generated in the nogg body in hot water without discharging it outside.

 [0014] Also, since the stick is fixed to the surface of the bag body and does not penetrate the nogg body, the stick body does not get in the way when the bag body is crushed, and the three-dimensional shape of the bag body is greatly deformed. Can be made.

[0015] Due to the deformation of the bag body, the liquid in the bag body containing a large amount of the extract can be removed from the bag body. Can be forcibly discharged. Further, the liquid can be allowed to flow into the bag body by lifting the stick and restoring the bag body to its original shape. By repeating this operation, the amount of liquid in and out of the bag body increases and decreases, and the beverage powder can be extracted sufficiently thickly.

 [0016] The attachment position of the stick is not limited as long as it is the surface of the bag body, but the top surface of the nod body is preferable. The shape of the knob body can be greatly deformed. For example, when the shape of the bag body is a tetrahedron, the bag body is preferably fixed to the apex. The distance between the stick attachment position and the beverage powder inside the nodule body is increased, and the deformation of the three-dimensional shape of the bag body can be increased.

 [0017] Further, "the degree to which the three-dimensional shape of the bag body is deformed" refers to an extent to which the stick mounting position force can contact or approach the bottom surface of the bag body. Also, the sticking area between the stick and the bag body should be as small as possible. The stick does not get in the way when crushing.

 [0018] In order to maintain the rigidity of the stick, it is preferable to form a strip having a thickness of 0.4 mm or more and a width of 3 mm or more, more preferably a strip having a thickness of 0.6 mm or more and a width of 5 mm or more. If it is smaller than the above range, sufficient rigidity cannot be maintained, and it is considered difficult to crush the bag body.

 [0019] The beverage extraction knob is desired to be compacted at the time of shipment and storage. Therefore, the stick can be bent by plastic deformation. By folding the stick, the entire beverage extraction knob can be made compact. Also, bend it at an appropriate position on the stick and hook it on the top edge of a cup or server.

 The invention's effect

 [0020] According to the present invention, since the stick has rigidity, the nod body can be immersed in hot water and crushed. In addition, since the stick is fixed to the surface of the bag body, the stick body does not get in the way when the bag body is crushed, and the three-dimensional shape of the bag body is greatly deformed.

 BEST MODE FOR CARRYING OUT THE INVENTION

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a beverage extraction bag of the present embodiment, FIG. 2 is a partially broken perspective view of the beverage extraction bag, and FIG. 3 is a perspective view showing a state in which the beverage extraction bag is also crushed with a stick. 4 is a view showing the usage state of the beverage extraction bag, FIG. 5 is a view showing the process of folding the beverage extraction nog, and FIG. 6 is a view showing a modification of the beverage extraction bag of the present embodiment.

 [0024] As shown in FIGS. 1 and 2, the beverage extraction nozzle / group 1 is formed into a tetrahedron shape, and the bag body 3 filled with the beverage powder 2 therein, and the apex of the bag body 3. It consists of a synthetic resin stick 4 fixed to the surface.

[0025] The material of the bag body 3 is a spunlace nonwoven fabric that is a filter material. Spunlace nonwoven fabric mixes several types of fibers such as extra fine fibers to prevent powder leakage as a filter, long fibers to give strength, and binder fibers, and entangles the fibers with each other by a water stream. It is formed. The fiber material is PET. Note that the material of the bag body 3 is not limited to the above, and other known filter materials such as filter paper or filter cloth using natural fibers such as norp or plastic fibers may be used. Good.

 [0026] The shape of the bag body 3 is a force formed in a regular tetrahedron shape, but is not limited to this. As shown in FIG. 6, the bag body 3 may be formed in another three-dimensional shape such as a rectangular shape. The tetrahedral shape can be formed by a known method. Specifically, the end portions of the band-shaped filter material are formed into a cylindrical shape by ultrasonic welding or heat welding, and then one open end is closed by ultrasonic welding or heat welding and shifted 90 degrees from it. If the other open end is closed by ultrasonic welding or heat welding, a tetrahedron can be formed.

 [0027] The bag body 3 is filled with an appropriate amount of ground coffee beans. In the present embodiment, the beverage powder 2 may be filled with other beverage powders such as tea, green tea, barley tea, oolong tea, soup, seasonings, and crude drugs filled with coffee. The filling of the beverage powder 2 is performed after the one open end of the cylindrical shape is closed by ultrasonic welding or heat welding in the manufacturing process of the above-described nogg body 3, and the other open end is ultrasonically welded or filled. It should be closed and sealed by thermal welding.

 [0028] The stick 4 is a force formed in a strip shape having a thickness of 0.6 mm and a width of 4 mm. However, the present invention is not limited to this. Further, the strip shape is not limited to a straight shape, and may be other shapes such as a bellows shape, a wave shape, a curved shape, and the like. The stick 4 is fixed to the surface of one apex of the tetrahedron of the bag body 3 by ultrasonic welding or heat welding, and has a tag 4a at the upper end. In addition, the material of the stick 4 is a thermoplastic resin, has a rigidity capable of crushing the bag body 3 to such an extent that the three-dimensional shape of the nodge body 3 is deformed, and is folded by plastic deformation. It is considered a material that can be tuned. Specifically, Forte (trade name, manufactured by Sekisui Chemical Co., Ltd.) is used as the stick 4. The stick 4 is formed by stretching a thermoplastic resin such as polyethylene at a high magnification.

 [0029] Since the beverage extraction bag 1 having the above-described configuration gives the stick 4 rigidity, the bag body 3 can be immersed in hot water. Hot water power S Can penetrate into the body of the bag and improve the extraction volume. In addition, it is possible to dissolve the hot gas generated in the nogg body in hot water without discharging it outside.

Further, as shown in FIG. 3, the beverage extraction nog 1 can crush the bag body 3 with the stick 4. Also, since the stick 4 is fixed to the surface of the bag body 3, When the body 3 is crushed, the stick 4 does not get in the way, and the three-dimensional shape of the bag body 3 can be greatly changed.

 [0031] Due to the large deformation of the bag body 3, the liquid containing a large amount of the extract in the bag body 3 can be forcibly discharged out of the bag body 3. In addition, the liquid can be caused to flow into the bag body 3 by pulling up the stick 4 and returning the bag body 3 to its original shape. By repeating this operation, the amount of liquid in and out of the nodule 3 increases and the beverage powder 2 can be extracted sufficiently thick.

 [0032] In addition, by crushing the nod body 3, pressure is applied to the nod body. Along with this, pressure is applied to the coffee beans, and a higher coffee can be extracted.

 [0033] Furthermore, when the bag body 3 is crushed with the stick 2, beverage powders can be mixed. Beverage powder can be easily brought into contact with hot water and extracted more densely.

 [0034] Further, since the stick 2 is formed of a material that can be bent by compositional deformation, it is bent at an appropriate position and hooked on the edge of the server 5 or the cup as shown in FIG. be able to. Stick 2 is rigid so you don't have to worry about it slipping off. Therefore, if you leave it as it is, Stick 2 will not sink into the water.

 [0035] Further, as shown in FIG. 5, the stick 2 can be folded. Specifically, after folding one vertex of the tetrahedron so that it overlaps with the vertex to which stick 2 is fixed (left figure in Fig. 5), fold stick 2 so that the folded vertex is sandwiched (in Fig. 5). Right figure). By folding in this way, the beverage extraction bag 1 can be made compact. Note that the folding method is not limited to this, and it may be folded further smaller by sticking the stick 2.
