Some bags are used by tearing the eyes or the like to open the mouth of the bag and injecting hot water.
[0016]
BEST MODE FOR CARRYING OUT THE INVENTION
The palatable beverage that can be applied to the palatable beverage bag with a support of the present invention is not particularly limited, and includes a wide range of beverages such as coffee, iced coffee, black tea, cocoa, oolong tea, other healthy teas, sencha, barley tea, and kelp tea. ing. Among them, coffee is most suitable for the extraction bag with the upper support of the present invention. Also, the cup can be applied to various types of cups such as a demitas type, a glass cup, and a morning glory type cup in addition to a usual cup for coffee or tea.
[0017]
The supporter of the palatable beverage bag with the supporter of the present invention has a shape in which a circular sheet made of paper is bent at right and left folds and two rectangular sheets 5, 5 'are superimposed. When using the palatability beverage bag, a punching portion is provided at a portion where the lower ends of the four sections provided at the lower portion of the paper support contact the edge of the cup, and the edge of the cup is fitted to the cutout portion, The feature is that the bag can be held in a stable state on the cup by fitting and fixing the edge of the cup into the circular gap provided at the end of the punched portion.
[0018]
Here, the shape of the punched portion shown in FIG. 1 has a shape specially devised so as to be adapted to the edge of the cup having various shapes, and is fitted to the edge of the cup to stabilize the bag. It plays an important role in maintaining state. The punched portion having such a shape has a structure in which the stability of the support-equipped bag on the cup is remarkably enhanced. For this reason, for example, a cutting line having an oblique inclination is inserted in the middle part of both ends of the support sheet described in Japanese Utility Model Publication No. 5-13324, and the section at that part is turned back to open the space between the front and rear sheets to open the bag. It is not necessary to add other means for increasing the stability, such as increasing the stability.
[0019]
The diameter of the cup held by the paper support is not always constant, and there is considerable variation, but the variation can be adjusted by adjusting the mutual bulge of the front and back sheets of the paper support so that the support can match it. It has a structure. For this reason, the material of the support needs to have appropriate elasticity and plasticity.
[0020]
The material of the support of the present invention needs to be made of paper. This is because paper is most suitable as a sheet material having both appropriate elasticity and plasticity as described above. The type of paper is not particularly limited, but slightly thick paper is preferable, thin paperboard laminated with a polymer resin is preferable, and high quality paper or cardboard subjected to waterproofing can also be used.
[0021]
As described above, the extraction bag of the present invention can be widely used as long as it has a filterability, but a nonwoven fabric containing ultrafine fibers having a fineness of 0.2 denier or less is more preferable because of its excellent extractability. For example, the most important properties required for a filter to contain coffee with excellent aroma and richness are that the coffee particles do not leak into the liquid and that they adsorb and remove the fats and oils contained in the coffee liquid. Therefore, the oil film does not float on the surface of the cup. These are all factors that hinder the taste of coffee, and if mixed with fine particles, the tongue feels bad, and if oils and fats float on the surface of the cup, they are not preferred because they glisten.
[0022]
As a material for preventing the leakage of fine particles and improving the adsorbability of fats and oils, nonwoven fabrics containing ultrafine fibers having a fineness of 0.2 denier or less are particularly excellent. Therefore, a nonwoven fabric containing such ultra-fine fibers is more preferable as the material of the bag of the present invention. Such ultra-fine fibers are produced, for example, from a thermoplastic polymer by a melt blow method, and polypropylene, polyethylene or the like is used as the type of the thermoplastic polymer. In addition, by using a composite nonwoven fabric of such a nonwoven fabric layer of ultra-fine fibers and a support layer made of fibers having a normal thickness, the filterability and the mechanical properties of the filter cloth can be improved.
[0023]
Means for attaching the extraction bag to the support is not particularly limited, but fusion or sticking can be applied. In the case where the bag is heat-fusible and the support is also a paper laminated with a polymer resin, heat-sealing is preferred.
[0024]
