Description

[Detailed description of the invention] The present invention relates to a device made of a sheet of paper or resin film, which is usually flat in shape, but which can stand on its own when opened to create a funnel-like structure. .

Conventionally, filter paper has been used to brew coffee, but the filter paper is not used alone, but is used together with a funnel-shaped device such as a dripper. However, conventional drippers are bulky, making them inconvenient to carry, and difficult to carry on trips, picnics, etc. Furthermore, it is expensive and cannot be disposable. Furthermore, although various paper cups have been used in the past, they cannot be folded and are bulky, making them inconvenient to carry.

The present invention is an attempt to eliminate such drawbacks of the conventional technology.It is made of paper or film sheet material and usually has a flat shape for convenient portability.
We created an inexpensive foldable funnel-like device that can stand up on its own when opened, creating a funnel-like structure, and can be used as a dripper when used with filter paper, or as a container when used with water-impermeable film. The purpose is to provide.

The foldable funnel-like device of the present invention consists of two overlapping sheets of approximately inverted trapezoidal shape, the sheets having a horizontal fold line dividing the sheet into a container portion and a base portion. , a fold line extending perpendicularly to the base portion from the intersection of a central vertical fold line, an inclined fold line near both side edges of the container portion, and the horizontal fold line, and a fold line extending from the intersection point to the base portion; and a fold line extending in a triangular shape, and the two sheet materials are bonded to each other at a portion outside the fold line near the side edge of the container portion.

Hereinafter, embodiments of the present invention shown in the accompanying drawings will be described. FIG. 1 is a plan view of a foldable funnel-shaped device according to the present invention. This funnel-shaped device consists of two substantially inverted trapezoidal sheets 1 which overlap each other. The two sheets 1 are made of paper or resin film with appropriate hardness and have the same shape. When these sheet materials 1 are made of paper, the surface of the paper is coated with a resin layer such as polyethylene that provides waterproofness and heat sealability. The sheet material 1 has a horizontal fold line 4 dividing the sheet material into a container part 2 and a base part 3, a vertical fold line 5 in the center, and inclined fold lines 6 near the side edges on both sides of the container part 2. , a fold line 7 extending vertically from the intersection point A, A of the fold line 6 and the horizontal fold line 4 to the base portion, and a fold line 8 extending in a triangular shape from the intersection points A, A to the container portion 2 are formed. . These fold lines are formed so that the sheet material can be easily folded at these points.
It may be a perforation or may be formed by stamping. The two sheet materials 1 are adhered to each other at a portion 9 outside the fold line 6 near the side edge of the container portion 2 (the portion shown as hatched in the drawing).

Next, in order to open the funnel-shaped device shown in Fig. 1, first bend the base part 3 horizontally on both sides along the fold line 4, and then open the upper end opening of the container part 3 from side to side. Open to. Next, as shown in FIG. 3, push up the center part of the base part 3 and bend it along the fold lines 5 and 7, and at the same time turn the part of the container part 2 surrounded by the fold line 8 and the horizontal fold line 4 inward. Fold in. In this way, a stable funnel-like structure is created in which the central part of the base part 3 enters the triangular fold line 8, and since there are horizontal parts at both ends of the base part 3, the state shown in FIG. It can be made independent. FIG. 4 is a top view of FIG. 3. As shown in Figure 1, the sheet material 1 is glued only at both edges and not at the center of the bottom, so a small slit 10 is formed in the center of Figure 4 to allow liquid to flow down. can be done.

A free-standing funnel-shaped device as shown in FIGS. 3 and 4 can be used as a brewer for brewing coffee, tea, etc. by placing a filter paper inside. At this time, since this funnel-shaped device is simply placed on the cup, it can be used with various cups, teacups, etc. of different diameters. Furthermore, by placing a film that does not allow water to pass through inside the funnel-shaped device, it is also possible to use it as a self-supporting cup.

By the way, since it is time-consuming to arrange filter paper or film in the funnel-shaped device shown in FIG. 3 later, it is also possible to arrange them in advance. That is,
As shown in FIG. 5, a V-shaped folded filter paper or film 11 is sandwiched between two sheet materials 1 so that its lower end is located at the horizontal fold line 4, and the hatched portion 9 is inserted into the filter paper. Or bond it together with a film. In this way, it can be used as a brewing device or a cup by simply opening it, making it extremely easy to handle. Alternatively, regular coffee or black tea may be pre-filled in a funnel-shaped device with filter paper sandwiched therebetween and then sold. The foldable funnel-like device shown in Figs.
A method of feeding paper, folding it in half, heat-sealing it, and cutting it (die-cutting), or feeding the material 13 and backing material 14 separately, sealing them at the same timing, and cutting them as shown in Fig. 7. It can be manufactured at low cost by various methods. In addition, the method shown in FIG. 5 is an inexpensive method in which the paper material 15 is folded in half as shown in FIG. It can be manufactured to

Because the present invention has the above-mentioned structure, it is usually flat and convenient to carry, and when in use, it opens to create a self-supporting funnel-like structure and can be used as an extraction device or container.Moreover, it can be manufactured at a low cost, so it is disposable. It has various excellent effects such as:
