[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a bag containing powdered raw materials which can easily extract beverages such as coffee or tea simply by pouring boiling water.

[0002]

2. Description of the Related Art Conventionally, a simple coffee bag in which a filter paper bag enclosing coffee powder is placed on a cup and poured so that regular coffee can be easily put in at home or in an office is commercially available. The structure is described, for example, in Japanese Utility Model Application Laid-Open No.
No., Jpn.
No. 6 is known.

However, in the conventional beverage extraction bag such as the above-mentioned coffee bag, even if the upper edge of the filter paper bag is opened and the upper edge is held open to pour boiling water into the filter paper bag, the opening is not maintained. There was a drawback that it was not possible to perform the treatment sufficiently and the opening diameter was small, so that hot water was difficult to pour.

Therefore, a frame-like supporting member made of cardboard is adhered near the upper edge of a gusseted filter paper bag containing a powder material such as coffee powder so that the filter paper bag is sandwiched from both sides. A beverage brewing bag has been devised in which the arms protruding from both sides of the filter paper bag are provided with folds and knobs so that the gusset can be expanded by forming a flat Y shape. In this beverage extraction bag, the filter paper bag can be held in a wide open state by pushing the knob portion inward and bending the arm portion into a flat Y shape on both sides of the filter paper bag, thereby expanding the filter paper bag. Therefore, the above disadvantage can be solved.

[0005]

[0005] By the way, this beverage brewing bag can be used at any time so that a required number of bags can be used.
It is sold in individual plastic bags and sealed.However, in the conventional beverage extraction bag, the arms always open outward due to the elasticity of the cardboard support member. There is a problem that it is difficult to store it and therefore it is difficult to use an automatic packaging machine.

SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned problems, and comprises a frame-shaped supporting member formed of cardboard near the upper edge of a gusseted filter paper bag containing a powder material such as coffee powder. inner There adhered so as to be sandwiched from both sides, a fold and knob portion so as to arm portion may expand the gusset becomes plane Y-shaped projecting from the filter paper bag opposite sides of the support member is provided, the arms Engage with each other when folded
In order to form a notch, cuts inclined in alternate directions are formed at the edges of the knobs on both sides .

[0007]

The arms can be prevented from opening outward by folding the arms on both sides inward and engaging the cuts of both knobs.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the accompanying drawings. A filter paper bag 1 containing powdered materials such as coffee powder has gussets 2 and 2 on both sides, and a sewing machine is provided on the upper edge thereof. An eye 3 is provided, and the upper edge of the filter paper bag 1 can be opened by breaking upward from the perforation 3.
Reference numeral 4 denotes a frame-shaped support member formed of cardboard, and the support member 4 is adhered so as to sandwich the filter paper bag 1 from both sides. Arms 5 and 5 of support member 4 protruding from both sides of filter paper bag 1 are provided with folds 6 and 7 so that they can be bent into a plane Y shape, and the tips are used as knobs 8 and 8. And the knob part 8,
V-shaped cuts 9, which are inclined in alternate directions, at the edges of 8,
9 is formed. The lower edge 9 of the arms 5, 5 is cut into a waveform.

In the beverage extraction bag configured as described above,
When the arms 5, 5 are folded inward as shown in FIG. 2 and the cuts 9, 9 are engaged with each other, the cuts 9, 9 are engaged because the inner edges of the cuts 9, 9 are inclined in opposite directions. As it is held in its engaged state without coming off as long as it is pulled straight,
It is housed in the plastic bag 10 as it is, so that it is kept airtight and its freshness and fragrance can be maintained until it is opened. At the time of use, the plastic bag 10 is opened and the cuts 9, 9 are disengaged.

Then, the upper edge of the filter paper bag 1 is opened at the perforation 3, and both the knobs 8, 8 are pinched by a fingertip and pushed inward, so that the arms 5, 5 are flat as shown in FIG. The gussets 2 and 2 are folded in a Y-shape and the upper edges of the filter paper bag 1 can be largely opened. Therefore, as shown in FIG. 5, the arms 5, 5 are placed on the upper edge of the cup 10, and the hot water is removed from the filter paper bag 1.
By pouring into the upper edge opening, the extract of the powder raw material 9 in the filter paper bag 1 can be dripped into the cup 10. As described above, the powder raw material 9 of the arms 5, 5 is formed in a corrugated shape so as to prevent slipping and to be stably supported on the cup 10.

[0011]

[Effect of the invention] As described above, the beverage extraction bag of the invention is:
In a beverage extraction bag provided with a fold and a knob so that it can be bent in a plane Y shape on an arm of a frame-shaped support member supporting the filter paper bag, when the arm is folded inward, The arms are held in the folded state by engaging the cuts formed with each other, so that the arms are compact, easily stored in a small bag such as a plastic bag, and the packaging is facilitated, and the usability is improved. There are advantages.
