Description

[Detailed Description of the Invention] The present invention relates to an extremely novel blank plate for a coffee dripper that has never existed before.

Traditionally, coffee drippers have only been made of ceramic or plastic injection molded, and these are bulky and inconvenient to carry around on picnics, etc., so the only option is to make do with instant coffee. The reality was that it was impossible to enjoy a very authentic cup of coffee. The present invention eliminates such conventional inconveniences and provides a blank board for a paper coffee dripper that is not bulky because it becomes two completely flat small paperboards when carried, is inexpensive, and is disposable. It is something.

To explain one embodiment of the present invention with reference to figures, FIGS. 1 and 2 are plan views of a funnel-shaped portion A and a flange B, respectively, which are constituent members of a blank plate for a coffee dripper according to the present invention. be. The funnel-shaped part A is made of paper whose inner surface is coated with polyolefin resin, and rectangular inclined plates 1 and 2 are arranged in series on both sides above and below the central transverse fold line a, and approximately on both left and right sides of the upper inclined plate 1. Triangular end plates 3 are connected through a fold line c with a cut line b in the center, and triangular end plates 4 are connected through a fold line d on both left and right sides of the lower inclined plate 2, and each end line 4 is Outer gable boards 5 of dimensions corresponding to the lower part of the gable boards 3 are connected to the upper end side via the broken line e, and each outer gable board 5
An insertion piece 6 for insertion and engagement is connected to the cut line b on the upper end side via a fold line f, and a funnel hole 7 is formed approximately in the center of the center transverse fold line a across the inclined plates 1 and 2. drilled,
A small hole 8 is formed above the fold line e, and a small notch 9 is formed at a position corresponding to the small hole 8 on the lower end of the end plate 3. The flange B has a horizontal width approximately equal to the horizontal width of the inclined plate 1 at the center of the disc 10, and a vertical line approximately twice the length of the perpendicular line drawn from the small hole 8 to the fold line e until it reaches the fold line d. A substantially rectangular hole 11 having a width is bored, and a small protrusion 12 for insertion and engagement into the small hole 8 is provided from the center of the left and right sides of the hole 11.

For assembly and use, first, as shown in Fig. 3, fold the outer gable plate 5 along the center transverse fold line a and the fold lines c, d, e, and f, and insert the outer gable plate 5 while folding it over the outer surface of the gable plate 3. Assembly of the funnel-shaped part A is completed by inserting and engaging the piece 6 into the cut line b, and then inserting the lower part of the assembled funnel-shaped part A into the hole of the flange part B as shown in FIG. 11, and at the same time insert and engage the small protrusions 12 on both sides into the small hole 8 and the small notch 9 to connect the funnel-shaped part A and the flange part B, completing the assembly. When brewing coffee, insert a filter paper M into the apparatus assembled as described above as shown in FIG. It is sufficient to place it on the cup N so that the flange B is in contact with it and pour hot water into it.

Incidentally, when inserting the filter paper M in the above description, it is suitable for the case where the angle α between the fold lines c and d shown in FIG. Therefore, the gable boards 3 and 4 and the outer gable board 5
The angle on the side of the central transverse fold line a is preferably about 40°.

Since the present invention is configured as described above, it has the following remarkable effects.

As shown in Fig. 3, the assembled funnel-shaped part A has an inverted roof shape, with fold lines c,
c and the broken lines d and d are parallel ridge lines.

The horizontal cross section is rectangular, and the ridge line is located at a corner of the rectangular horizontal cross section.

Therefore, by making the hole 11 of the flange B into a rectangular shape, the lower part of the funnel-shaped part A fits tightly into the hole 11, and the ridge lines come into close contact with the four corners of the hole 11.

As a result, the funnel-shaped part A is firmly held by the hole 11 of the flange part B, and is also firmly maintained in an inverted roof-like shape.

The assembled funnel-shaped part A has fold lines e and e.
There is a constant force at work that tries to bend the whole thing into a flat, folded state.

This force presses the edge of the hole 11 on the side where the small protrusion 12 is provided outward.

Therefore, the lower part of the funnel-shaped part A fits tightly into the hole 11.

On the other hand, the end plate 4 and outer end plate 5 of the funnel-shaped portion A fitted into the hole 11 are constantly pressed inward by the end edge of the hole 11 on the side where the small protrusion 12 is provided.

As a result, the force of bending outward along the fold lines e and e is reduced, and the funnel-shaped portion A is maintained in an inverted roof-like shape.

By inserting and engaging the small protrusion 12 into the small hole 8 and the small notch 9, the connection between the funnel-shaped part A and the flange part B is further strengthened, and the shape retention of the funnel-shaped part A is further improved. strengthened.

As described above, the funnel-shaped portion A and the flange portion B are firmly connected, and the funnel-shaped portion A is firmly maintained in shape.

Therefore, even if a large amount of hot water is poured during use, the funnel-shaped part A will not come off from the flange part B, nor will the funnel-shaped part A be deformed.

Hot water can be poured while looking into the cup N through the notch 13.

It has a simple structure and is easy to assemble and use.

Since it has a flange B, it can be used for cups of any size.

When not in use, the funnel-shaped portion A can be folded flat along the central transverse fold line a and the fold lines e and e, so it is not bulky.

In addition, the structure is simple and the materials are inexpensive. Therefore, it is disposable and you can easily enjoy real coffee anytime and anywhere.
