Description

[Detailed Description of the Invention] The present invention relates to a filter paper for filtering tempura oil, etc., and its purpose is to make it extremely easy to assemble into a usable shape close to an inverted cone.

Conventionally, filter paper for filtering liquids such as tempura oil has been stapled to maintain its inverted conical shape, but this has the drawback of requiring time and effort to assemble.

Especially in the case of tempura oil, it is often filtered at high temperatures of around 160°C to 180'C, so if adhesives or heat seals are used to hold the filter paper in an inverted conical shape, The holding part cannot withstand the high temperature of tempura oil.

The present invention has been devised to address such problems, and aims to provide a filter paper that can be assembled extremely easily without the need for staples, adhesives, etc. as described above.

Hereinafter, the present invention will be explained based on drawings showing an example of implementation.

In the figure, 1 is a filter paper made of nonwoven fabric or paper using rayon fiber, etc., and has a regular octagonal shape with a folded piece 3 on half of one side 2. Two elongated holes 5 and 6 are formed so as to sandwich a folding line 4 formed between the center of the octagon and the center of the regular octagon.

Further, on the side where the bending piece 3 is not formed, a folding line 8 is also formed between the intersection of the -side 2 and the side 7 connected to the -side 2 and the center of the regular octagon. A long hole 9 is formed close to half of the negative side 7 located on the folding line 8 side.

The folding lines 4 and 8 are formed to extend in a square shape from the center of the regular octagon.

Note that the elongated holes 5 and 6 formed close to the side 2 are not completely hollowed out, and the material located inside the elongated holes 5 and 6 is cut out with a small flap 5a.

It is connected to the upper end as 6a.

Therefore, when using such filter paper 1, as shown in FIG. Then, bend the bent piece 3 inward and insert it into the matching long holes 9, 5.6.

As a result, the portion above the elongated holes 9 and 5 is pressed down by the bent piece 3 to prevent expansion.

Also, the flap 5a. 6a holds down the bent piece 3 to prevent the bent piece 3 from being pulled out.

With the above steps, the filter paper 1 is assembled into a shape close to an inverted cone as shown in FIG.

The filter paper 1 assembled as shown in FIG. 4 is used, for example, when filtering tempura oil by placing it on a wire mesh provided at the upper end of a container.

Although the above embodiments have been described using a regular octagonal filter paper 1, it is also possible to use a circular filter paper.

The filter paper of the present invention can be implemented as described above, and can be assembled extremely easily without the need for conventional staples or adhesives. It is convenient for

Furthermore, the filter paper of the present invention can be used not only for tempura cooking but also for filtering liquids such as chemicals.
