In order to assemble the strainer 4 as shown in FIG. 2 from these constituent members, first, the mesh bag 2 is attached to the fixed frame 1, and the mesh bag 2 is attached to the projection 1 c of the fixed frame 1. Holes 2b may be fitted respectively.

Next, the holding members 3 are attached to the opposite sides of the fixed frame 1 (the side without the handle 1d).
This mounting is performed by fixing the protrusion 3 c of the fixed frame 1 to the hole 3
In this case, the holding rod 3b of the holding metal fitting 3 enters the mesh bag 2 and presses the side wall surface of the metal bag 2 to prevent the mesh bag 2 from floating. The frame 2 a of the mesh bag 2 is pressed from above by the abutment plate 3 a of the holding member 3 and is fixed to the mounting portion 1 a of the fixed frame 1. It is to be noted that the presser fitting 3 may not only be simply dropped into the fixed frame 1 but also be engaged with the convex portion 1c or may be strongly fixed by using an appropriate fixing means.

The strainer 4 assembled in this manner is used by being installed in a grease interceptor 5 as shown in FIG.

When the mesh bag 2 serving as the strainer body is full of cooking debris or the like, the strainer 4 is taken out of the grease interceptor 5 by holding the handle 1d of the fixed frame 1 and the holding metal fitting 3 is removed. The net bag 2 is removed from the fixed frame 1 by lifting using the handle 2c, and the net bag 2 is discarded.

Thereafter, a new mesh bag is attached to the fixed frame 1 in the same manner as described above, and the presser fitting 3 is fitted to form a strainer 4, and the strainer 4 is installed in the grease interceptor 5 again. Can be returned to.
By repeating this, only the net bag 2 is disposable, and the net bag is always replaced with a new one, so that the net bag is not used in a clogged state. For this reason, the original function as a strainer can be sufficiently exhibited, and cleaning is not required at the time of dumping garbage.

In the above-described embodiment, the method of taking out the entire strainer 4 when the garbage is discarded is adopted.
It is also possible to adopt a method of taking out only the outside and replacing it. In this case, for example, as shown in FIG. 4, a rectangular mounting portion 6 is fixed to the inner wall of the grease interceptor 5 ', and a convex portion 6a for fixing the net is provided on the mounting portion, and the mesh bag 2 is mounted. Hardware 3
Alternatively, it may be fixed by pressing. That is, a configuration using the mounting portion 6 instead of the fixed frame 1 is adopted. In addition, if the fixing frame 1 is fixed in the grease interceptor, it is also possible to implement the replacement method of only the mesh bag 2 without using the mounting portion 6.

FIG. 5 shows a structure in which the length of the fixed frame 1 or the mounting portion 6 can be freely adjusted, and can be applied to grease interceptors of various sizes. That is, one side is composed of two side members 7 and 8, and elongated holes 7 a and 8 a are formed in these side members, respectively, and the two side members 7 and 8 are fixed by bolts 9 and nuts 10. It can be set to the length that you want.

Reference numerals 11 and 12 denote metal fittings provided with convex portions 11a and 12a for fixing the net, respectively, and holes 11b and 12b provided in the metal fittings.
And bolts utilizing the long holes 7a, 8a of the side members 7, 8
13 and 14 and nuts 15 and 16 can be fixed to the side members 7 and 8, respectively. At this time, the thicknesses of the metal fittings 11 and 12 are set differently so that the heights of the convex portions 11a and 12a are exactly the same.

Further, depending on the size of the grease interceptor, as shown in FIG. 7, the mounting portion 6 'of the mesh bag may be mounted on only two opposing sides. In addition, although not shown, when a grease interceptor is provided with a net receiving edge or a receiving shelf on the inner wall thereof, it is possible to directly attach a net bag using the edge or the receiving shelf, Alternatively, it is also possible to mount via a mounting frame or the like.

It is possible not only to dispose the net bag alone but also to use the entire strainer in a disposable manner. However, it is required that other materials besides the net bag be formed of inexpensive materials in terms of cost. Will.

FIG. 8 shows still another embodiment of the present invention, in which a synthetic resin mesh bag 22 is attached to the outside of a fixed frame 21 and attached along the opening end of the mesh bag 22. A rough hook portion 22a is provided, and the hook portion 22a is hooked on a convex portion 21c provided on the mounting portion 21a of the fixing frame 21, so that the mesh bag 22 can be fixed. The handle 21d of the fixed frame 21 is
It is provided inside the fixed frame 21 so as not to be in the way when it is covered.

In this case, there is no need to use a holding member for fixing the mesh bag as in the above embodiment, and it is not necessary to provide a synthetic resin frame attached to the open end of the mesh bag. Therefore, the cost can be reduced by reducing the number of parts.

As described above, the fixed frame 21 with the mesh bag 22 attached thereto is used by being installed in the grease interceptor in the same manner as in the previous embodiment. For example, as shown in FIG. Attachment part 21a of fixed frame 21 to the attachment part provided
Is completed, the installation is completed, and the mounting portion 21 of the fixed frame 21 is
The upper portion of the mesh bag 22 is sandwiched between the a and the mounting portion of the grease interceptor, and the mesh bag is also in a stable state.

At the time of this installation, the four legs of the fixed frame 21
Since 21b is located in a columnar shape at the four corners inside the mesh bag 22, the lifting of the mesh bag 22 and the narrowing to the center portion are prevented beforehand, so that the installation work can be performed easily and efficiently. Can be.

Although not shown, the hook 22 of the mesh bag 22 is not shown.
If a is formed in a bag shape and the string is passed in a ring shape, the fixed frame 21 is removed when the accumulated dust is discarded, and the string is pulled when the mesh bag 22 is removed from the fixed frame 21 so that the mesh bag 22 is pulled. Can be closed, and the net bag 22 can be hung as it is and discarded at the disposal point. Hook 22 of net bag 22
Since a has a bag-shaped double structure, the strength is also increased. on the other hand,
A new mesh bag can be attached to the fixed frame 21 and reused.

If the mesh bag 22 is formed larger than the fixed frame 21, it is easy to attach and detach the mesh bag 22 and it is convenient. If the mesh bag 22 is too large and the opening end of the mesh bag is slackened, the opening end is formed. Tighten the pin as much as possible along the fixed frame 21, and overlap the last remaining part with the convex part
If it is fitted to 21c, the slack can be eliminated. It is preferable to fit an appropriate stopper such as an o-ring only at the location of the projection.
