Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tool used for extraction of regular coffee and the like.

[0002]

[Prior Art]

 Conventionally, in this type of tool, as shown in JP-B 27-9577, JP-B 28-587, and JP-B 50-34203, filtration is performed between the upper frame and the lower frame. It had a structure in which the periphery of the body was sandwiched to support the filter body.

In recent years, in order to easily extract coffee using regular coffee, an extraction tool as shown in Japanese Utility Model Publication No. 63-39330 has been devised. This is composed of an upper frame body and a lower frame body, and a fitting groove provided on one side and a ridge provided on the other side, which draws in the peripheral edge of the filter body (paper filter) and fits into the fitting groove. It has a structure in which it is detachably connected through a connecting part, and the filter body is stretched by being pulled in at the connecting part. Extraction is performed while placing this extractor on a cup or the like. Each time, the filter body could be replaced.

[0004]

[Problems to be solved by the device]

 However, in the case of the cup stationary type structure in which the upper and lower frame bodies are detachably connected so that the filter body can be easily replaced, and the filter body is stretched by sandwiching the filter body in the connecting portion, Since the liquid was exposed to the outside from the connecting portion, the liquid might ooze out from this filter at the time of extraction, and there was a possibility that the liquid would drip outside the cup.

Further, since the filter body is stretched and the back surface thereof is a flat surface, the liquid is likely to remain in the form of drops even after the extraction is completed, and when the extractor is removed from the cup or the like. However, there was a problem in that it dripped outside the cup, and it was necessary to handle it carefully while using the extractor at hand.

In view of the above-mentioned circumstances, the present invention eliminates the exudation from the filter body without impairing the easy exchangeability of the filter body due to the attachment / detachment of the upper and lower frames, and prevents the liquid from remaining on the back surface of the filter body. The goal is to make it easier to handle the extraction tool.

[0007]

[Means for Solving the Problems]

 The present invention has been made in consideration of the above-mentioned problems, and the filter body is stretched by sandwiching the peripheral edge of the filter body between the upper frame body and the lower frame body. The body is connected to the upper and lower frame bodies via a connecting portion formed of a fitting groove and a ridge provided on the other of the upper and lower frame bodies and which is fitted in the fitting groove by drawing in the peripheral edge of the filtration body. The fitting device is detachably connected to the fitting groove, and the fitting groove has an undercut portion, and the protrusion has a convex portion that engages with the undercut portion. Is provided in a size such that the undercut portion and the convex portion are not engaged with each other at a locking position, and the lower frame body is provided with a rib whose upper edge is in contact with the back surface of the stretched filter body. The above-mentioned problem is solved by providing a pouring tool.

[0008]

[Action]

 In the present invention, the peripheral edge of the filter body is drawn into the connection part so that it does not protrude to the outside of the connection part. Then, the ribs allow the liquid to easily be transmitted from the back surface of the filter body and drop, so that the liquid does not stay on the back surface of the filter body.

[0009]

【Example】

 Next, the present invention will be described in detail based on the embodiment shown in FIGS. 1 to 6 show a first embodiment. The spouting tool 1 comprises a bottomless upper frame body 2 which is expanded in a horn shape, and a lower frame body 3 in which a mounting leg 30 is extended in four directions and a bottom center is opened and a bottom face 31 is inclined toward this opening. , A disc-shaped filter body 4 made of a paper filter or the like.

As shown in FIG. 3, a protrusion 21 having a convex portion 20 is provided on the lower edge of the upper frame body 2, while the lower frame body 3 has a protrusion 21. As shown in FIG. 4 and FIG. 5, an annular fitting groove 32 corresponding to the protrusion 21 is provided at the upper edge. There is an undercut portion 33 extending over the inner peripheral surface of the fitting groove 32, and the projection 21 is fitted into the fitting groove 32 to lock the convex portion 20 in the undercut portion 33. The connecting portion 5 is formed, and the upper frame body 2 and the lower frame body 3 are detachably connected via the connecting portion 5 including the protrusion 21 and the fitting groove 32. As shown in FIG. 6, the filter body 4 is stretched so that its peripheral edge is pulled into the connecting portion 5. Further, this filter body 4 has a diameter such that the peripheral edge does not reach the undercut portion 33, and even if the peripheral edge is pulled into the connecting portion 5, it does not protrude outward from the connecting portion 5.

As shown in FIGS. 4 and 5, the lower frame 3 is provided with ribs 6 whose upper edges are in contact with the back surface of the filter body 4 on the bottom surface 31 in four directions. When the extraction liquid is extracted using, the extraction liquid (for example, coffee) does not stay on the back surface of the filter body after the extraction and is dropped along the ribs 6, so that the drainage of the filter body is improved.

In the above-described first embodiment, the connecting portion 5 is composed of the protrusion 21 provided on the upper frame body 2 side and the fitting groove 32 provided on the lower frame body 3 side. The present invention is not limited to this, and as shown in the second embodiment shown in FIGS. 7 to 11, the fitting groove 22 is provided at the lower edge of the upper frame 2 and the lower frame is provided. It is also possible to provide a protrusion 34 on the upper edge side of 3 and form the connecting portion 5 from the fitting groove 22 and the protrusion 34. In this second embodiment, as shown in FIG. 10, ribs 6 are provided in a cross-shaped arrangement pattern. As shown in FIG. 11, the undercut portion 33 and the convex portion 20 are formed of the fitting groove 22 and the protrusion 34, and the undercut portion 33 and the convex portion 20 engage with each other. The periphery is pulled in and stretched.

[0013]

As described above, according to the present invention, the extractor has the filter body stretched by sandwiching the periphery of the filter body between the upper frame and the lower frame. The frame body and the lower frame body are composed of a fitting groove provided on either one of the upper and lower frame bodies and a ridge provided on the other and fitted into the fitting groove by drawing in the peripheral edge of the filter body. The fitting groove is detachably connected, and the fitting groove is provided with an undercut portion, and the protrusion has a convex portion that engages with the undercut portion. The body is provided with a size such that the peripheral edge does not reach the locking portion between the undercut portion and the convex portion, and the lower frame body has a rib whose upper edge is in contact with the back surface of the stretched filter body. Therefore, there is no protrusion on the periphery of the filter body, and it is possible to prevent the liquid from seeping out from the connection part. Moreover, it is possible to provide a convenient extractor that can be drained without liquid remaining on the back surface of the filter body after extraction and can be provided with excellent practicality.
