Description

[Detailed explanation of the idea] The present invention relates to a filter case for a copying machine.

This kind of filter case is generally replaced and discarded together with the filter when the filter is replaced.

On the other hand, a conventional filter case is one in which a shaped article made of resin is assembled and a filter holder made of a shaped article of metal such as aluminum is attached thereto.

Therefore, the cost is high, the economic loss of discarding the filter every time the filter is replaced is very large, and the disposal of the discarded product is also difficult.

The present invention solves the above problems and provides a copying machine filter case that is inexpensive, causes little economic loss even if it is discarded every time the filter is replaced, is easy to dispose of after disposal, and is easy to manufacture. This is something to aim for.

An example of implementation of the present invention will be explained below based on the drawings.

In the drawing, A is the main body of the filter case, which is made up of two picture frame-shaped box frames a that are connected to each other via a connecting piece 1 that is assembled by bending a sheet of paper board A', and are stacked one on top of the other.
, l).

That is, the paper board A' is made of thick paper such as cardboard, and the outer wall surfaces 2, 2 of the front and rear box frames a, l) are continuously connected to both left and right edges so that the connecting piece 1 is located in the center. ′, bottom wall surface portions 3, 3′, inner wall surface portions 4, 4′, and top wall surface portions 5, 5′ are sequentially provided via fold lines 6, 6′, 7, 7′, 8, 8′, 9, 9′. It is being

The connecting piece 1 has a width slightly wider than the sum of the widths of the two upper wall surfaces 5 and 5', and has a tab 10 extending from its side edge.

This lug piece 10 is used for picking when installing and removing the copy machine.
Of the two fold lines 11 and 12 provided halfway in the extension direction, it is once folded back to the connecting piece 1 side at the base side fold line 11, and further bent upward at the tip side fold line 12.

Then, the folded portion is adhesively fixed to the connecting piece portion 1.

The outer wall surface parts 2, 2' and the inner wall surface parts 4, 4' are shaped so that those 2, 4 of the front box frame a are slightly wider than those 2', 4' of the rear box frame b. The wall parts 5, 5' and the bottom wall parts 3, 3' of the rear box frame b are shaped to have a slightly wider width than those of the front box frame a. .

Further, side wall surface portions 13.13' are provided on the outer wall surface portions 2 and 2', respectively, continuously extending from the side edges thereof via bends 14 and 14', and further in the extending direction of the side wall surface portions 13.13'. Insert pieces 15, 15' extend through fold lines 16, 16'.

The above side wall surface parts 13.13' are the box frames a, l) to which they belong.
The width is approximately the same as that of the upper and lower wall portions 5, 3, 5', and 3'.

Flaps 17.17' and 18.18' are provided on the side edges of the upper wall portions 5, 5' and the bottom wall portions 3, 3', respectively, with fold lines 19.1.
9', 20. 20'.

Furthermore, rectangular window holes 22, 22', 23.23' are formed in the outer wall surface parts 2, 2' and the inner wall surface parts 4, 4', leaving frame edges 21.21' of approximately the same width at the peripheral edges, respectively. Open.

Thus, the filter paper board A' is made by bending the two box frames a and b connected by the connecting piece 1 on both sides of the connecting piece 1 along the fold lines, gluing them at the necessary places, and The inner wall surfaces 4 and 4' of the box frames a and l) are overlapped back and forth to form upper wall surfaces 5 and 5, respectively.
' is glued on the back side of the connecting piece 1.

Note that the width of the connecting piece 1 is the upper wall surface portion 5 of the front and rear box frames a, l),
Since the shape is slightly wider than the sum of the widths of the front and rear box frames a and l), a gap is created between the inner wall surfaces 4 and 4' of the front and rear box frames a and l). Spacer-2
4, the inner wall surface portions 4, 4' are adhesively fixed to each other.

At this time, the width of the spacer 24 is set at the frame edge 2 of the box frame a, l).
A concave groove 25 is formed in the thickness of the spacer 24 at the outer peripheral edge of the spacer 24 so as to have a width narrower than 1.21'.

The main body A shaped like this has a filter 26 on its rear box frame b, and a filter holder 2 on its front box frame a.
7 are fitted respectively.

The filter holder 27 is formed by cutting cardboard into a strip and bending both lengthwise ends upward to form a U-shape, which are connected in the length direction, and are attached to the front box frame a. The frame is bonded across the side wall surface portion 13 of the rear box frame b, and the filter 26 fitted into the rear box frame b is held down and supported by the side edge on the side of the rear box frame b.

Such a filter case is used by inserting it into a filter holder B provided in a copying machine, but at this time, the protrusion 29 protruding from the inner surface of the side wall 28 of the filter holder B is inserted into the filter case body A. It engages with the concave groove 25 to guide the insertion of the main body A and prevent rattling after installation.

Since the present invention has the above structure, it has the following advantages.

(1) Since it is curved with cardboard, it is inexpensive and there is little economic loss even if it is discarded together with the filter each time the filter is replaced.

(2) Assembly is easy because the paper board can be bent along the fold lines.

(3) Since the product can be kept in an unfolded state until just before shipping, it can be stored efficiently without taking up much space.

(4) The filter can be removed and burned, making it easy to dispose of the waste.
