The extractor 1 shown in FIGS. 1 and 2 is an example of an extractor that supplies coffee 6 or the like without enclosing it. The main body 2 of the extraction tool 1 is formed of an inexpensive sheet (for example, cardboard) in order to reduce the weight, reduce the cost, and make it disposable. The main body 2 is for fixing and storing the filter paper 4 on a predetermined inner surface and for stably setting the extractor 1 on the coffee cup 5, so that the folding portion 21 is vertical and the opposite side walls 22 are provided. When the end portions of the side walls 22a are opened, the bottom portions 23 and 23a of the side walls 22 and 22a are formed so that they can stand upright. The expandable holding piece 25 or 25a is provided on each of the openable and closable ends of the side walls 22 and 22a through a ruled line 24 or 24a, respectively.
And the upper ends of the expansion holding pieces 25 and 25a are adhered to each other to form a stopper 26. Therefore,
When the main body 2 of the extractor 1 opens the side walls 22 and 22a and pushes down the stopper 26 to position the expansion holding pieces 25 and 25a substantially horizontally, the main body 2 is opened at a predetermined angle and stably held. You can Then, when the side walls 22 and 22a of the main body 2 are opened at a predetermined angle, the recesses 27 or 27a that can be fitted into the upper edge of the coffee cup 5 are provided at the bottom portion 23 at appropriate intervals.
Alternatively, two are provided in each of 23a. The filter paper 4 stored in the inner surface of the main body 2 is coffee 6 or the like.
Is formed in a funnel shape for easy extraction and efficient extraction of coffee 6 when pouring hot water, and the open upper edges 41 and 41a are provided on the upper portion 28 or 28a of the main body 2 by appropriate means ( For example, they are fixed by sticking. Therefore, when the side walls 22 and 22a of the main body 2 are opened, the upper edges 41 and 4 of the filter paper 4 are
Since 1a is opened at an appropriate angle, it becomes easy to put coffee 6 or the like. The extractor 1A shown in FIGS. 3 and 4 is an example of the extractor 1 in which coffee 6 is stored in the filter paper 4 in advance and supplied. The body 2 of the brewing tool 1A is formed so as to have substantially the same appearance as the body 2 of the brewing tool 1 shown in FIG. 1, but the filter paper 4 in which coffee 6 and the like is bulged and compactly accommodated,
Further, in order to facilitate opening, the opposing upper portions 28 and 28a of the side walls 22 and 22a are discontinuously point-sealed 29,
