Description

[Detailed Description of the Invention] The present invention relates to a simple coffee pack, and particularly to a coffee pack that allows regular coffee to be obtained with just one touch.

So-called instant coffee, which is made by powdering the infused liquid, has been commercially available as a simple coffee, but this instant coffee has a much inferior flavor compared to professionally brewed coffee, and has become increasingly popular due to the recent trend towards luxury. It's starting to feel uncomfortable. Extracting coffee using the drip or siphon method requires special equipment, which is difficult to carry when hiking, etc., and is cumbersome to brew even at home or in the office, and is troublesome to clean up afterwards. However,
Coffee packs in which coffee powder is sealed in a filter paper bag have been proposed, but these have problems such as the coffee powder tends to scatter when the filter paper bag is opened, and the coffee solution tends to overflow from the opening of the coffee pack when hot water is poured. There were many problems with usability.

This invention was created in view of the above points, and its purpose is to create a lightweight, compact, and convenient to carry product so that you can easily enjoy regular coffee.
The present invention aims to provide a simple coffee pack that is not only simple in structure and inexpensive, but also has excellent usability.

Hereinafter, the present invention will be specifically explained based on illustrated embodiments.

Figures 1 to 3 all show an embodiment of a simple coffee bag according to the present invention, 1 is a filter paper bag, and the bottom 11 is approximately W-shaped, made of a material with a filtering function such as Japanese paper. Folded back, both side edges 12,
12' and the upper edge 13 are bonded together. The filter paper bag 1 contains coffee powder 2 obtained by roasting and grinding coffee beans.

Reference numeral 3 denotes an internal filter, which is formed by folding a material with better water permeability than the filter paper bag 1, such as thin Japanese paper or Japanese paper with a coarse fiber structure, into a V-shape at the bottom. Adhesive is applied to the opposing surfaces and outer surfaces of the upper edge 31 and both side edges (not shown) of the internal filter 3, and the coffee powder 2 enclosed in the filter paper bag 1 is coated with adhesive.
When forming the filter paper bag 1 by press bonding, it is sandwiched and bonded inside the filter paper bag 1.

Reference numeral 4 denotes a support member consisting of a knob portion 41 and a reinforcing portion 42. The support member 4 is made of two strip-shaped cardboard sheets each coated with an adhesive on opposing surfaces. It is bonded along and in the vicinity thereof, that is, on both outer surface portions of the upper edge portion 13 slightly below the bonding surface. The knob portion 41 is formed by causing one end of the support member 4 to protrude from the one side edge 12 of the filter paper bag 1. The upper side of the support member 4 serves as a guide when opening the filter paper bag 1, and the outer surface of the upper edge 31 of the internal filter is integrally bonded to the filter paper bag 1 at least below this guide line.

The simple coffee pack of the present invention is constructed as described above, and is flattened to a thickness of only the coffee powder 2, and sold in plural packs in a sealed bag made of aluminum film or the like.

To brew coffee, first, the upper edge 13 of the filter paper bag 1 is cut off along the upper side of the support member 4 along with the upper edge 31 of the internal filter 3, and the bag is opened. At this time, the internal filter 3 acts like an inner lid to prevent the coffee powder 2 from scattering. Note that since the filter paper bag 1 and the internal filter 3 are made of a material that is relatively easy to break, such as Japanese paper, the upper side of the support member 4 made of cardboard or the like serves as a guide, allowing them to be opened easily.

After that, an opening 14 where the filter paper bag 1 and the internal filter 3 are integrated is formed into a cylindrical shape, and a knob 41 is positioned on the coffee cup, and hot water prepared separately is poured into the opening 14. Then, the hot water is first filtered to remove impurities by the internal filter 3 and then diffused, and dripped onto the coffee powder 2 to become a coffee solution. At this time, even if too much hot water is injected, the internal filter 3 can prevent the coffee solution from directly overflowing from the opening 14, and the internal filter 3 can be made of water-permeable material such as relatively thin Japanese paper. Since it is made of superior material, it can quickly filter hot water. After that, the coffee solution is filtered through the filter paper bag 1 and the coffee liquid drips into the coffee cup. In this embodiment, the knob portion 41 and the reinforcing portion 42 are integrally formed of cardboard or the like, so that the filter paper bag 1 can be sufficiently supported during the above-mentioned extraction of coffee.

After the extraction has been completed, the filter paper bag 1 may be disposed of in a trash can after sufficiently draining water.

In the above embodiment, the filter paper bag 1 and the internal filter 3 are each made of Japanese paper, but other materials having a certain filtration function, such as nonwoven fabric or filterable resin sheets, may be used. The two may be made of different materials, such as the bag being made of relatively thick Japanese paper and the internal filter being made of thin non-woven fabric. Furthermore, if the bottom surface of the internal filter is formed with a mountain fold, the filtration and diffusion of hot water will be better. Further, the upper edge of the internal filter is formed at least at the opening 1 of the filter paper bag when the filter paper bag is opened.
4, and does not necessarily have to reach the upper edge of the filter paper bag.
Furthermore, although the support member 4 in the above embodiment is not essential to the present invention, instead of the support member 4, perforations are cut in the longitudinal direction of a strip of cardboard to form the upper edge 13 of the filter paper bag 1. If it is glued along the filter paper bag 1
Various improvements are possible, such as making it easier to open the package. Furthermore, the present invention can be applied to extracts other than regular coffee, such as tea packs.

As described above, the present invention provides an internal filter 3 whose upper edge 31 is integrally bonded to the inside of the opening 14 of the filter paper bag 1 in the space above the coffee powder 2 sealed in the filter paper bag 1. Since the internal filter 3 has better water permeability than the filter paper bag 1 and constitutes a simple coffee pack, it can be easily constructed and manufactured at low cost, and is flat, lightweight, and not bulky, and does not require any other special equipment. Not only is it convenient to carry around, but it also has extremely practical effects, such as being able to quickly extract coffee liquid with a single touch without leaking coffee powder or coffee solution when opening the package or pouring hot water into it. It is something.
