Description

[Detailed description of the invention] The present invention relates to a package for roasted coffee powder. In particular, the present invention includes a package in which coffee powder is hermetically sealed and a filter for filtering the coffee powder is integrated into the package. The coffee is prepared by transferring the enclosed coffee powder to the filter paper bag of the filter when the package is opened, and then placing the bag on the coffee cup and pouring hot water into the bag to extract the coffee liquid in a drip manner. The purpose of the present invention is to provide a powder package.

In general, commercially available coffee is not only sold in the form of roasted beans, but also pre-ground into powder for convenience in beverages. The aroma of coffee is easily lost, and the rate of loss of the unique flavor of coffee due to humidity is much higher than in the bean state. For this reason, coffee powder sold in powder form is usually canned or airtightly packaged with aluminum foil, but currently commercially available coffee powder weighs only a few dozen grams.
Since the product is packaged in quantities of several hundred grams for a large number of people, the entire package must be opened even for a small number of people, which poses a major problem in preserving the remaining amount after opening. .

The present invention was devised in view of these problems, and consists of a container body made of synthetic resin with a flange-shaped adhesive piece integrally attached to the opening edge of the storage part formed in a dish shape, and a central part of the main plate body. A through hole is formed in the plate, two parallel fold lines are provided on both sides of the through hole, and a pair of support pieces are provided on both side edges, while an opening for a foldable filter paper bag is provided on the back side of the main body of the plate. It is composed of a filter and a sealing film, which are integrally attached along the periphery of the through hole with the edges attached, and the storage part of the main body of the container is filled with food for one to four people, for example. A small amount of roasted coffee powder is placed in advance, and the adhesive piece is adhered to the main surface of the plate of the filter, and the folded filter paper bag covers the storage part, while the back side of the filter is covered with a small amount of roasted coffee powder. The coffee powder is characterized in that the sealing film is attached and the peripheral edge thereof is adhered to the back surface of the plate main body or the adhesive piece of the container main body, so that the coffee powder stored in the storage part is hermetically sealed. The purpose is to provide a package, and when the package is opened for use, the coffee powder is directly transferred from the container main body to the filter paper bag of the filter, placed on a suitable container such as a coffee cup, and hot water is poured. To provide a coffee powder package with excellent preservability and handling properties, from which coffee liquid can be immediately extracted and used as a beverage.

Examples illustrating the present invention will be described below.
To explain its features in detail, Fig. 1 is a central longitudinal sectional front view of the package according to the present invention, Fig. 2 is an exploded view of the above figure, and Fig. 3 is an exploded perspective view. The main body of the package of the present invention is a container, 2 is a filter, and 3 is a sealing film attached to one side of the filter 2 to airtightly enclose the coffee powder contained in the package.

The package of the present invention consists of these three components. To explain in more detail, the main body 1 of the container is made of a plastic plate having a required thickness and is formed into a dish shape.
A storage section 5 for storing coffee powder 4 is provided. A wide flange is integrally provided at the opening edge of this storage portion, and an adhesive piece 6 is provided thereon.

On the other hand, the filter 2 has a through hole 8 in the center of a plate main body 7 made of plastic or paper with appropriate rigidity, and two fold lines 9, 9 are formed in parallel on both sides of the through hole. A filter paper bag 11 formed on a bag using filter paper is attached to the back side of the main body of the plate, and the opening edge of the filter paper bag is is integrally attached to the opening edge of the through hole. In the example shown in the drawings, two wires 12, 12 are attached to the back surface of the plate main body 7 in parallel so that the fold line 9 intersects perpendicularly, and when the supporting pieces 10, 10 are bent with the fold line 9 as a base point, The rigidity of the wires 12, 12 allows this supporting piece to rise at a desired bending angle with respect to the main body of the plate.

As will be described later, when this filter 2 is used, the support pieces 10, 10 are folded along the crease lines 9, 9 so that they rise approximately at right angles to the plate main body 7, as described above, but in the packaged state. As shown in FIG. 1, both supporting pieces 10, 10 are folded into the back surface of the plate main body 7 to make it flat. And the filter paper bag 11 attached to this back side
is folded and placed between the plate main body 7 and both supporting pieces 10, 10, so that the entire filter is folded into a flat shape.

The container main body configured in this way and the filter are formed separately, and first, coffee powder 4 for the number of people who usually use it at one time, such as for one to four people, is placed in the storage part 5 of the container main body 1. A filter 2 is attached so as to cover the top surface of the container.

As shown in the figure, the filter 2 is attached so that its surface is in contact with the main body 1 of the container, and the through hole 8 formed therein is aligned with the opening of the storage section 5, and the filter paper bag folded flat is attached. 11, the container-based adhesive piece 6 and the surface of the filter 2 that is in contact with the adhesive piece 6 are bonded by adhesive or heat sealing so as to substantially close this opening. After that, an airtight sealing film 3 such as plastic film or aluminum foil is placed on top of the flattened filter 2, and its periphery is glued or heat-sealed to the adhesive piece 6 of the container. They are then joined together to form a package.

Therefore, according to the present invention, coffee powder for a small number of people can be stored in the container-based storage section, so the entire amount can be consumed after opening the container, eliminating the problem of storing the remaining amount as in the past. You can always drink the amount you need in a fresh state without leaving any residue. and,
Since this package is made airtight by joining the container main body 1 and the sealing film 3, the coffee powder does not come into contact with the outside air, so it naturally retains moisture and its flavor. It can maintain its freshness for a long time without losing its fragrance.

Furthermore, an advantage of the present invention is that after opening the container, the coffee powder stored in the main body of the container can be directly transferred to the filter paper bag 11 of the filter 2, and the coffee liquid can be extracted in a drip style using this filter. .

That is, when opening the package of the present invention, first remove the film 3.
The filter paper bag 11 of the filter is peeled off to expose the filter paper bag 11 of the filter, and then the bottom of the filter paper bag is pulled open and turned over so that the main body 1 of the filter is facing up. It will fall into the filter paper bag 11. After that, when the joint between the container-based adhesive piece 6 and the surface of the filter 2 is peeled off and opened, the filter becomes separate and independent.

Figure 4 shows the filter 2 that has been made independent by the above opening.
is placed on the coffee cup 13 and the coffee liquid is extracted.
The filter paper bag 11 that has received the coffee powder 4 can be extracted into the cup by raising the coffee powder 4 so as to stand up substantially at right angles along the folding lines 9 and 9 and placing it on the edge of the cup.

In addition to the above-mentioned effects, the present invention is extremely convenient because it allows you to immediately transfer the encapsulated coffee powder to the filter and then simply pour hot water to drink the coffee. If one or two people's servings are determined, coffee of the optimum strength can be immediately obtained by selecting a container accordingly.

As described above, the container main body 1 and the filter 2 are connected to the opening of the storage section 5 of the container main body and the filter paper bag 1 of the filter.
1 are joined in a facing state, so when transferring the coffee powder from the storage part to this filter paper bag, it does not overflow, and since it is directly transferred from the storage part, there is an advantage that it can be processed in an extremely hygienic manner.

By the way, in the illustrated example, the support pieces 10, 10 provided on the filter 2 are stored in a folded state.
This is based on considerations to reduce the overall size of the package, so the support piece is extended flat and aligned on the same plane as the plate main body 7, and the container main body is placed on the surface as shown in Fig. 5. The adhesive piece 6 may be brought into contact with the other surface and joined, and the film 3 may be brought into contact with and joined with the other surface to airtightly cover the folded filter paper bag.

In this case, each of the above-mentioned joints does not interfere with adhesion using adhesives, but in addition to molding the container body 1 from plastic, the plate body 7 of the filter is made of a resin-treated sheet, and the film 3 is made of plastic film. Alternatively, if heat sealing is made possible by using a composite film such as aluminum foil laminated with plastic film, packaging becomes easier and products that are easier to open can be obtained.
