Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a coffee dripper mainly made of paper, which can be disposable after one-time use and is easily disposed of. This coffee dripper is constructed by using a paper cup and integrally attaching a small paper tray capable of storing coffee beans to the outer bottom surface of the paper cup.

<Conventional technology> This type of conventional coffee dripper is as follows:
The technique of attaching a small container to the bottom of the paper container main body as shown in Japanese Utility Model Application No. 167629/1983 developed by the applicant (first known technique), or the technique of attaching a small container to the bottom of the paper container body, or
A technique for attaching a plate body having a flange made of a plastic molded product to the bottom surface of a container as shown in Japanese Patent No. 143626 (second known technique), A technique in which the coffee powder is stored in the bottom of the stepped structure (third known technique), or a technique in which an inner bottom is formed inside the container body as shown in Japanese Utility Model Application Publication No. 150690/1983. Techniques in which coffee powder is stored between the base plate and the base plate (fourth known technique) are known.

<Problem to be solved by the invention> However, in both the first known technique and the second known technique mentioned above, in order to insert and attach the small container to the bottom of the container body from the inside of the container, a large opening is provided in the center of the bottom. At the same time, it is necessary to make the surroundings protrude, and the processing is complicated, and it is not possible to use paper cups that are conventionally available on the market as they are. There was a problem that it was difficult to do so and the cost was high.

Furthermore, in both the third and fourth known techniques described above, a step is provided at the bottom of the cylinder or a midsole is attached to the inner bottom, thereby storing coffee powder at the bottom of the cylinder itself. However, the processing is complicated in these cases, and commercially available paper cups cannot be used as they are, and it is difficult to assemble and process them continuously using automatic machines, resulting in high costs. I had a problem.

The coffee dripper according to the present invention is a completely new technology developed in view of these conventional problems.

<Means for solving the problems> The coffee dripper according to the present invention is a technology that fundamentally improves the above-mentioned conventional problems, and its gist is that the outer surface is made of a plastic layer with an opening at the bottom. It consists of a paper cup laminated with paper cups and a small round tray whose outer circumferential surface is laminated with a plastic layer with a flange on the upper edge and an opening on the bottom. The opening of the small round tray is covered with a filter paper stuck to the bottom, and the flange of the small round tray filled with ground coffee is covered with the outer bottom of the paper cup. The small round tray is integrally attached to the bottom of the paper cup by heat-bonding it into a ring shape.

<Function> As mentioned above, in the present invention, the flange of the small round tray is thermally bonded to the outer bottom surface of the paper cup, so conventional commercially available paper cups can be used as is. , a small round tray can be easily attached from the outside of the paper cup. Therefore, a small round tray prefilled with ground coffee beans can be attached to the bottom of the paper cup in an assembly line by an automatic machine.

Since a plastic layer is laminated on the outer surface of the paper cup and the small round tray, the two can be easily connected by heat sealing, high frequency sealing, etc. Furthermore, since the entire structure is mainly made of paper, there is no problem of pollution and it can be easily disposed of.

<Example> An embodiment of the coffee dripper according to the present invention will be specifically explained with reference to the drawings. FIG. 1 is a partial cross-sectional perspective view of the dripper according to the present invention, FIG. 2 is a vertical cross-sectional view thereof, Figure 3 is a bottom plan view of the paper cup;
The figure is a bottom plan view of the small round tray.

In Figs. 1 to 4, 1 is a generally commercially available paper cup whose entire outer surface is laminated with a layer of plastic such as polyethylene. An opening 3 is perforated therein. Further, a filter paper 4 capable of covering the opening 3 is attached to the upper surface of the bottom surface 2 of the paper cup 1.

Next, 5 is a small round tray formed by pressing cardboard with a plastic layer laminated on the outer surface, and a filter paper 6 is provided on the bottom of the tray by heat sealing or the like. A predetermined amount of ground coffee beans 7 is filled. The flange 8 of this small round tray 5 is connected to the paper cup 1.
The paper cup 1 is thermally bonded in a ring shape to the bottom surface 2 of the paper cup 1, so that the small round tray 5 is integrally attached to the bottom surface of the paper cup 1. Furthermore, there are several openings 10 on the bottom surface 9 of this small round tray 5.
is provided on the bottom surface 2 of the paper cup 1 and covered with the filter paper 6.

Since the coffee dripper according to the present invention has the above-mentioned structure, when using it, it is necessary to
is placed on the coffee cup 11, and hot water is poured into the paper cup 1.The hot water is passed through the small round tray 5 through the opening 3 of the bottom surface 2, and the coffee beans 7 are eluted and poured into the paper cup 1. Desired coffee can be easily obtained in a coffee cup 11 by dropping it from an opening 10 of a small round tray 5.

<Effects of the invention> Since the coffee dripper according to the invention has the structure and function described above, commercially available paper cups can be used as they are, and a separately provided small round tray can be used for the paper cups. It can be easily attached to the bottom by thermally gluing it from the outside.

Therefore, the overall structure is simple, the work is easy, assembly work can be carried out using automatic machines, etc., and mass production can be carried out at low cost.

In particular, the small round tray is thermally welded to the bottom of the paper cup via the flange, so it is stable and has features such as no risk of peeling.
