As a material for forming the tubular paper body, for example, 200 to
Thick paper such as 340 g / m ² water-resistant card paper and ivory paper is suitable.

Next, the bag 3 will be described. The bag 3 used in the present invention is not particularly limited as long as it is a material having a filtering function. However, in consideration of workability when forming the bag, the material itself has thermal adhesiveness, or Preferably, the innermost layer has thermal adhesiveness. For example, a nonwoven fabric having water permeability such as polyolefin such as polyethylene or polypropylene, or polyester, or a layer containing a thermoplastic resin such as olefin or polyester such as polyethylene or polypropylene as the innermost layer 2 And filter paper having a three-layer structure.

The bag body 3 is formed by folding a long sheet made of a roll having thermal adhesive properties, for example, a filter paper having a three-layer structure containing modified polypropylene in the innermost layer by folding it in two parallel to the longitudinal direction. Or by folding the folded portions in a W-fold (gusset-fold) manner and superimposing them, and heat-bonding them in a predetermined shape (bonded portion indicated by reference numeral 32 in FIG. 1), and thereafter cutting and / or cutting. It can be manufactured by cutting the mold (in FIG. 1, the mold is cut into a substantially trapezoidal shape having a narrow folded portion).

The assembly of the tubular paper body 2 and the bag body 3 is performed by attaching the bag body 3 to the tubular paper body 2 as described above.
Is inserted into the bag body 3 so that the opening edge of the bag body 3 is substantially opposed to the center.
This is completed by folding back only one portion and attaching it to the outer surface of substantially the center of one opening edge (upper edge in FIG. 1) of the tubular paper body 2. Note that, in FIG.
0 is attached to the outer surface of the tubular paper body 2,
It may be attached to the inner surface of the tubular paper body 2. In any case, it is desirable that the sticking position of the tubular paper body 2 be the upper edge in FIG. 1, and this is because when the tubular paper body 2 is erected in a cylindrical shape during use, Since the bag 3 is adhered to the upper edge of the tubular paper body 2, both sides (the upper part in FIG. 1) of the bag 3 are lifted, and a large and reliable opening of the bag 3 is guaranteed. Because it is suitable for hot water and drip. The sticking of the tubular paper body 2 and the bag body 3 can be appropriately selected from hot melt type, solvent type, aqueous type, reaction type, pressure sensitive type and the like. Further, the back main plate 220 and the back auxiliary plate 2 of the blank 2 ′
Naturally, the adhesive for bonding the overlapped portion with the adhesive 21 can be appropriately selected from the above-mentioned adhesives.

The semi-finished product dripper 1 in which the bag 3 is assembled to the tubular paper 2 in this manner is then placed in the bag 3 to extract regular coffee powder, black tea, green tea leaves and other components to be extracted. Is filled from the opening of the bag body 3, and then the opening of the bag body 3 is heat-bonded so as to form the peelable bonding portion 31, and the dripper 1 of the present invention is provided.
Becomes

Next, a method of forming the peelable adhesive portion 31 in the opening of the bag 3 will be described. The peelable adhesive portion 31 has, for example, an ultrasonic horn (not shown) having a flat tip and an ultrasonic wave having a surface A on which fine projections B are formed in a staggered manner by knurling or the like as shown in FIG. Welding by applying ultrasonic vibration using an ultrasonic welding device (not shown) provided with a welding jig (in FIG. 6, the microprojections B are quadrangular pyramid-shaped projections). It was formed. As described above, the dripper 1 shown in the present embodiment attaches the bag body 3 to the tubular paper body 2, and thereafter, inside the bag body 3, the components to be extracted such as regular coffee powder, black tea and green tea leaves. Is filled from the opening of the bag body 3 and finally, the opening of the bag body 3 is ultrasonically welded so as to become the peelable bonding part 31, and the peelable bonding part 31 Is formed by ultrasonic welding from the outer surface of the tubular paper body 2 via the tubular paper body 2. However, it is very difficult to bond the inner surfaces of the openings of the bag body 3 releasably through the cardboard forming the tubular paper body 2 by a normal hot plate sealing method, an impulse sealing method, or the like. In addition, it takes time to bond, and the production efficiency is reduced, and the inner and outer surfaces of the tubular paper body 2 and the surface of the bag body 3 are easily burnt and browned. In addition, since the pressing becomes non-uniform near both ends of the three overlapping portions of the thick paper in the overlapping portion where the tubular paper body 2 is bonded, the thickness of the thick paper 3 in the overlapping portion of the opening where the bag body 3 is bonded is also increased. Insufficient seals such as missing seals occur near both ends of the sheet overlap portion, and it is difficult to use these methods.

As a sealing method for solving the above-mentioned problem, an ultrasonic welding method capable of selectively bonding a desired portion can be considered. An ultrasonic horn (not shown) having a flat tip and a flat surface are provided. When ultrasonic vibration is applied by applying ultrasonic vibration using an ultrasonic welding device (not shown) equipped with an ultrasonic welding receiving jig (not shown) having the following, the opening of the bag body 3 is closed. A good result was obtained without being scorched on the inner and outer surfaces of the tubular paper body 2 and the surface of the bag body 3, and the tubular paper body 2 was also adhered. Since the ultrasonic vibration energy is concentrated on the overlapped portion, the pressing adjustment and output adjustment for obtaining a good result are quite complicated, and although not shown, the overlapped portion of the tubular paper body 2 is bonded. The ultrasonic hoe Or if subjected to ultrasonic welding receiving jig, the alignment of the site and the overlapping portion subjected to escape processing is difficult. Therefore, as a result of diligent research, an ultrasonic horn having a flat tip (not shown)
And an ultrasonic welding jig having a surface A in which microprojections B are formed in a staggered manner by knurling or the like as shown in FIG. 6 (in FIG. 6, the microprojections B are exemplified by quadrangular pyramidal projections). The ultrasonic vibration energy is applied using an ultrasonic welding device (not shown) provided with the above-described configuration, so that the ultrasonic vibration energy is not excessively concentrated on the portion of the tubular paper body 2 corresponding to the overlapping portion. And found that the opening of the bag body 3 can be ultrasonically welded in a peelable manner without causing scorching on the surface of the bag body 3. By the way, in the embodiment, the staggered minute projections B are formed on the surface of the ultrasonic welding receiving jig (in FIG. 6, the minute projections B exemplify quadrangular pyramid-shaped projections). The surface of an ultrasonic welding jig (in FIG. 6, the microprojections B are exemplified by quadrangular pyramid-shaped projections) is flattened, and the staggered microprojections B are formed at the tip of the ultrasonic horn. It may be. The microprojections B are quadrangular pyramidal projections, and are arranged in a so-called iris shape. However, the present invention is not limited to this. For example, a triangular pyramid, a pyramid such as a pentagonal pyramid, or a conical shape may be used. Good thing.
