Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coffee packaging body,
In particular, the present invention relates to a coffee package that is integrally packaged with roasted coffee powder and a filter for brewing the coffee powder to extract and filter the coffee liquid.

As is well known, coffee is sold in the form of roasted beans or ground into powder.
Because roasted coffee absorbs moisture and deteriorates over time, it is usually sold in airtight packaging. However, the packaging in this case is usually one package containing enough for several dozen people, so if you take out the amount for a small number of people, the rest will be exposed to moisture as soon as the package is opened, so it must be packaged airtight. However, there were problems such as the need to transfer it to an airtight container for preservation.

Also, as is known, when drinking coffee, the coffee liquid must be leached in hot water and then filtered to remove the coffee liquid, and for this purpose, a percolator, siphon, or drip filtration is generally used. There was a problem that it was necessary to prepare a container, etc., and it was not as convenient as drinking instant coffee.

The present invention was invented in view of the special circumstances when brewing coffee, the circumstances in handling coffee, and especially the storage issues. A filter that extracts the coffee liquid from the coffee is sealed in a packaging bag, and when used, it is easy to make fresh coffee by opening the packaging bag, assembling the filter, and pouring boiling water. An object of the present invention is to provide a packaged product for coffee that can be obtained in the following manner.

The filter according to the present invention is composed of a support plate having a pair of support legs that can be expanded flatly, and a filter paper bag assembled to the support plate, and a predetermined amount of coffee powder is added to the filter paper bag in advance. When stored and not in use, the opening of the filter paper bag is closed with a removable lid formed on the support plate to prevent coffee powder from overflowing and to keep the coffee powder contained in the packaging bag in a stable state. In addition, when in use, by raising the support leg piece, it can stand directly on a container such as a coffee cup, and by separating the lid part, the opening of the filter paper bag is opened. ,
In this state, the coffee liquid in the container can be extracted directly by pouring boiling water.When enclosing the coffee powder in the packaging bag,
It is also extremely convenient for brewing and filtering coffee liquor.

Furthermore, in packaging the above-mentioned coffee powder, the amount for one or two small people is placed in a filter in advance and sealed in a packaging bag, so that the entire amount is consumed as soon as the packaging bag is opened. An object of the present invention is to provide a coffee package that avoids the problem of preserving the remaining amount in conventional packaging methods and is made compact and convenient to carry.

In addition, the present invention preliminarily stores coffee powder in a filter and seals it in a packaging bag, and then performs oxidation prevention treatment on the contents, such as by evacuating the inside of the packaging bag or filling it with inert gas. To provide a packaged product for coffee that has a high shelf life and allows the processes and operations to be carried out easily and completely.

Examples illustrating the present invention will be described below.
Other features will also be detailed.

Fig. 1 is a partially cutaway perspective view of a coffee packaging body according to the present invention, and Fig. 2 is a longitudinal sectional front view of the packaging body taken in cross section along the line of the above figure. 2 indicates a filter enclosed in this packaging bag together with coffee powder 3.

As shown in FIGS. 3 to 5, the filter 2 has a support plate 4 formed by cutting out a substantially rectangular sheet from a sheet having the required rigidity, such as a sheet of cardboard or synthetic resin.
A filter paper bag 5 is attached to the back of this support plate and assembled into one piece. At the same time, a lid portion 8 connected to the support plate through the uncut portion 6a is integrally provided in this portion, and a plurality of bending lines 9, 9 are formed on the left and right sides sandwiching the lid portion 8. Cut both side edges of the support plate 4 at the bending line, and insert a pair of symmetrical support leg pieces 1 here.
0 and 10 are provided.

In the figure, 11 indicates the lid portion 8 and a pair of supporting leg pieces 1.
0 and 10 are the center lines that serve as base lines when folding the support plate 4 in half;
Notches are formed on each edge of the filter 10 so as to be symmetrical about the center line, and these notches are used when the filter is placed on a container such as a cup, as will be described later.

On the other hand, the filter paper bag 5 is a bag for accommodating the coffee powder 3, and in this embodiment, the filter paper is shaped into a substantially rectangular shape as shown in FIG.
Fold this filter paper in half, and then add this transverse line 13.
and a transverse line 14,1 located midway between the upper and lower edges.
By applying adhesive to both side edges 15, 15 between the two transverse lines 14, 14,
It is formed into a flat bag with an opening edge. Then, the transverse lines 14, 14, that is, the portion from the opening edge of the bag to the upper and lower edges of the filter paper, are attached to the adhesive pieces 16, 1.
6, this adhesive piece is attached to the back surface of the support plate 4, and is assembled to the support plate 4 by adhering it with an adhesive applied along the periphery of both adhesive pieces.

By the way, when this filter paper bag 5 is in a normal state, the opening edges are aligned in parallel and the mouth is closed, as shown in FIG. In this normal state, the left and right width of the opening is made longer than the interval between the bending lines 9, 9 provided on the support plate 4, and the edges of the adhesive pieces 16, 16 extending from this opening are further When the width between the openings is formed to be larger than the diameter of the lid part 8 provided on the support plate 4 and is attached to the back surface of the support plate 4, the opening edges aligned in parallel, that is, the transverse lines 14, 14 are formed on the support plate. The opening of the filter paper bag faces directly below the lid 8, and the adhesive piece 1
The edges of the bags 6 and 16 are adhered to the back surface of the support plate 4 surrounding the lid part 8, so that the opening of the bag is closed by the lid part 8 and the support plate 4.

Incidentally, prior to adhering the filter paper bag 5 to the support plate 4, a predetermined amount of the coffee powder 3 is placed in the filter paper bag 5 in advance, and by closing the bag by adhering the filter paper bag, this coffee powder is absorbed into the bag. Try to confine it to

The filter formed as above is the coffee powder 3
In this embodiment, the filter is folded in two along the center line 11 of the support plate 4, and the filter paper containing the coffee powder 3 is placed in the filter paper bag 5. Support plate 4 with bag 5 folded in half
It is placed in between and sealed in the packaging bag 1. After doing so, either evacuate the air inside the packaging bag to create a vacuum, or
Alternatively, after degassing, it is filled with inert gas and sealed to form a package.

The present invention is constructed as described above, and the coffee powder contained inside the packaging bag is placed in a vacuum state or in an inert gas, and is completely cut off from contact with the outside air, which is effective in maintaining freshness. You can always get fresh coffee.

In the coffee package according to the present invention, when the coffee powder 3 is enclosed in the packaging bag 1, the coffee powder 3 is enclosed in the filter paper bag 5 of the filter. In case of degassing when filling with inert gas or inert gas, the coffee powder is not absorbed, so that reliable degassing is possible and the operation is extremely easy. Moreover, since the enclosed coffee powder is contained within the filter paper bag, which has excellent air permeability, the inside of the packaging bag can be completely degassed.

In addition, as explained in the above embodiment, since the support plate 4 is folded into the packaging bag and the filter paper bag 5 containing coffee powder is sandwiched between the support plates, the bag is enclosed in a packaging bag, which makes the coffee powder vulnerable to impact. The filter paper will be protected. Therefore, there is an advantage that the filter paper bag can be safely handled without being damaged, for example, when being transported or carried around. Furthermore, since the filter 2 can be made compact by folding, the package itself can be made smaller, which is extremely convenient for packing or carrying.

Furthermore, the most advantageous aspect of the present invention is that in addition to the above-mentioned packaging advantages, the coffee powder and the filter for filtering it are integrated into the packaging bag, making it extremely easy to use and hygienic. It is possible to obtain drip coffee.

That is, as mentioned above, the package of the present invention has excellent storage stability and is convenient to carry; however, since this package encloses the coffee powder 3 in the filter 2, The coffee liquid can be extracted immediately by opening the package 1, pulling out the filter 2, placing the filter in a suitable container such as a coffee cup, and pouring hot water into the container.
To explain this point in more detail, Figures 7 to 9 show an example of actual use. First, the packaging bag 1 is opened, the filter 2 is pulled out, and the support plate 4 is removed as shown in Figure 4. It is unfolded flat, and then the lid part 8 connected at the uncut part 6a is separated with fingers to open the opening part 7 of the filter paper bag 5 containing the coffee powder 3. After that, as shown in the figure, the left and right support leg pieces 10, 10 are bent at a substantially right angle along the bending line 9 provided on the support plate 4, and the cup 17 is folded using the notch 12 provided on the support leg piece. All you have to do is stand it up on the edge of the container and then pour boiling water over it.

By the way, the above figures 7 to 9 show coffee cup 1.
7 is an explanatory diagram showing an example in which the bending line 9 formed on the support plate 4 is selected in accordance with the difference in the diameter of the cup, and can be used for cups with different diameters, and FIG. FIG. 8 shows the case where the bent supporting leg pieces 10, 10 are erected along the outer bending line 9c, and FIG. 9 shows the case where the legs are bent along the bending line 9a. Bend and further intermediate bending line 9b
This shows the case where the outer bending line 9c is bent little by little to make the support leg pieces 10, 10 into arcuate curved surfaces. In particular, FIG. 9 shows an effective bending method for a cup in which the edge of the cup opens outward.

Using the notches 12, 12 formed on the edges of the support leg pieces 10, 10 raised in this way, the inner piece 18 is inserted inside the edge of the cup, and the two outer pieces 19, 19 is taken out of the cup and held from both sides to be fixed to the edge of the cup.

In this case, since the bending line 9 is an arcuate curve as described above, the support leg piece 1
If you stand up from 0 or 10, it will automatically curve and you will be able to stand up with a strong back. In addition, in this embodiment, both ends of the filter paper bag 5 are attached to the back surface of the support leg piece, so when the support leg piece is bent and stood up, the two ends come together, so that the filter paper bag 5, which is not fully closed, The opening of the bag 5 opens automatically, making it easy to pour hot water into the bag.

Incidentally, FIGS. 10 to 12 show a modification of the notch 12 described in the above embodiment, in which a U-shaped notch 21 is provided near the end edge 20 of both supporting leg pieces 10. This is another embodiment in which a tongue-shaped engagement piece 22 is cut out, and the edge of the coffee cup 17 is held between the inside and outside by the engagement piece 22 and the end edge 20, and the support leg piece 10 is made to stand up on the cup. .

That is, in this embodiment, instead of forming the two notches 12 at the leg ends of the support leg piece 10, one U-shaped notch is provided so that the inner pieces 18, 18 are provided with one U-shaped notch.
One tongue-shaped engagement piece 22 corresponding to the outer pieces 19, 19 is provided, and an edge 20 is left as a piece corresponding to the outer pieces 19, 19, so to speak, the outer pieces 19, 19, which were separate. 19 are formed in a continuous state so that they face the inner engaging piece 22, and both pieces have a tongue-shaped engaging piece 22 as shown in FIGS. 11 and 12. Like the inner piece 18, it is inserted into the inside of the edge of the cup, and the other end edge 20 is placed on the outside of the cup in the same way as the outer piece 19, and it is clamped from the inside and outside to stabilize the supporting leg piece on the cup. It can be fixed standing up.

As mentioned above, the filter can be assembled by simple work and can be placed independently on the cup.
Coffee liquid is extracted automatically by simply pouring hot water into the cup, making it extremely easy to handle. In this case, the filter stands up on the cup, and the inside of the filter paper bag and the cup can be seen from between the support legs, making it convenient to monitor the state of coffee extraction.

In addition, since the coffee powder stored in the filter is sealed in advance, it does not come into contact with hands and can therefore be handled hygienically. By specifying the cup to be used and determining the amount of hot water to be poured, the coffee concentration can be automatically kept constant, and the advantage is that the optimum concentration can be set in advance. .

In carrying out the present invention, the material of the packaging bag 1 is not particularly specified, but since it is necessary to make the inside airtight, for example, a synthetic resin film or a composite film made by laminating aluminum foil on a synthetic resin film is suitable. Also, when this type of film is used, heat sealing is possible, making the sealing work easier.

Further, in the embodiment described above, a substantially circular annular cutting line 6 is formed in the center of the support plate 4 of the filter, and an opening 7 and a lid 8 for closing this opening are integrally provided to open the opening. Although the opening section is assumed to be closed when in the sealed state, this lid section may not be necessary if the opening section is closed when folded like the filter paper bag 5 described above. Of course, the lid part 8
It goes without saying that the opening is not limited to being cut out from the support plate 4, but may be formed separately from a film and placed over the opening to close it so that it can be easily removed.

Further, in the above embodiment, bending lines 9, 9 were provided to form the supporting leg pieces on the support plate 4 of the filter, but as is clear from the explanation, these bending lines cause the supporting leg pieces to stand up. It serves as a reference point and a guideline, and in practice, it may be formed by making perforations, making shallow cuts on the surface of the support plate, or crushing and shaping with a press. .
