Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a package for coffee, and in particular, the present invention relates to a package for coffee, and in particular, the present invention relates to a package for packaging roasted coffee powder and a filter for brewing the coffee powder to extract and filter the coffee liquid. The present invention relates to packaging for coffee.

As is well known, coffee is sold in the form of roasted beans or ground into powder, but roasted coffee absorbs moisture and deteriorates over time, so it is usually is sold in an airtight package.However, the packaging in this case is usually enough for several dozen people, so if you take out the amount for a small number of people, the remaining amount will be lost as soon as the package is opened. Because it is exposed to moisture, there were problems such as having to transfer it to an even more airtight container for storage even though it was packaged airtight. Also, as is known, coffee is what you drink. In this case, the entire coffee liquid must be leached in boiling water and then filtered to extract the coffee liquid.For this purpose, it is generally necessary to prepare a percolator, a siphon, or a drip filter, etc. to make instant coffee. There was a problem that it lacked the convenience of drinking.

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 obtain fresh coffee by opening the packaging bag, assembling the filter, and pouring boiling water. An object of the present invention is to provide a coffee packaging body that can be used to store coffee.

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, thereby preventing the coffee powder from overflowing and stably enclosing it in the packaging bag. 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, the opening of the filter paper bag is opened, and in this state, boiling water is poured into the bag. The coffee liquid can be extracted directly into the container by pouring, making it extremely convenient for enclosing coffee powder in a packaging bag and for infusing and filtering the coffee liquid.

Furthermore, when packaging the above-mentioned coffee powder, the present invention preliminarily places an amount for one or two people in a filter and seals it 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 an entire package for coffee that avoids the problem of preserving the amount of IA in conventional packaging methods and is packaged in a small size for convenient portability.

Furthermore, the present invention allows coffee powder to be placed in a filter in advance and sealed in a packaging bag, and the inside of the packaging bag is subjected to oxidation prevention treatment, such as by vacuuming or completely filling with inert gas. To provide a flat, preservative coffee package that allows the process and work to be performed easily and completely when applying gold.

Hereinafter, the entire illustrated embodiment of the present invention will be explained, and all other 7% features will also be explained in detail.

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 along line ■-■ in the above figure, with reference numeral 1 shown in the drawings. 2 shows a packaging bag, and 2 shows a filter enclosed in the packaging bag C together with coffee powder 3.

As shown in FIGS. 3 to 5, the filter 2 includes a support plate 4 formed by cutting out a sheet having the required rigidity, such as a sheet of cardboard or synthetic resin, into a substantially rectangular shape, and a back surface of this support plate. The support plate 4 is made up of a filter paper bag 5 that is attached to and assembled into one body, and the support plate 4 is provided with a discontinuous cut line 6 of approximately the same shape in the center thereof to form an opening 7 and a The support plate and the lid part 8 connected via the uncut portion 6a are integrally provided, and a plurality of bending lines 9, 9 are formed on the left and right sides sandwiching the lid part 8, and the support plate is connected to the support plate by the bending lines. 4, and a pair of symmetrical support leg pieces 10 and 10'r are provided therein. In the figure, 11 indicates the lid 8 and a pair of support leg pieces 10.
12 is a center line that serves as a base line when folding the support plate 4 provided with the support plate 4 in half, and 12 is a notch formed at each edge of both support leg pieces 10, 10 so as to be symmetrical with the center line in between. This notch is 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 containing all of the coffee powder 3, and in this embodiment, as shown in FIG. Furthermore, adhesive is applied to both side edges 15, 15 between this transverse line 13 and a transverse line 14°14 located midway between the upper and lower edges, thereby bonding the above-mentioned both transverse lines 1.
It is formed into a flat bag with opening edges 4 and 14. Then, the transverse lines 14, 14, that is, the portions from the opening edge of the bag to the upper and lower edges of the filter paper, are used as adhesive pieces 16, 16, and all of these adhesive pieces are attached to the back side of the support plate 4, and both are attached. The piece is assembled to the support plate 4 by adhering it with an adhesive applied along the periphery of the piece.

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, i6 extending from this opening. When forming the gap so that the width is Q larger than the diameter of the lid part 8 provided on the support plate 4 and attaching it to the back surface of the support plate 4, ``the above-mentioned opening edges aligned in parallel, that is, the transverse lines 14, 14 are The opening of the filter paper bag should be aligned with the center line 11 provided on the support plate, and the opening of the filter paper bag should be directly below the lid 8, and the adhesive pieces 16, 16 should be aligned with the center line 11 provided on the support plate.
The edge of the bag is 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.

In addition, before 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. Rub the V to trap it in.

The filter formed as described above is enclosed in the packaging bag 1 with the coffee powder 3 housed in the filter paper bag 5, but in this embodiment, the filter is separated by the center line 11 of the support plate A filter paper bag 5 folded in half and containing all the coffee powder 3 is sandwiched between two folded support plates 4 and enclosed in a packaging bag 1.

After that, the air inside the packaging bag is evacuated to create a vacuum, or after the air is evacuated, it is filled with active 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. Or, when deaeration is performed when the inert gas is completely filled, there is no oxygen absorbed by the coffee powder, and therefore, reliable deaeration is possible and the work is extremely easy.

Furthermore, 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 dewaxed.

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 and enclosed, the support plate C allows the filter paper to be easily resistant to impact. will be protected. Therefore, for example, when transporting or carrying around, there is an advantage that the filter paper bag can be handled safely without being damaged.Furthermore, due to this folding,! Since the Sl filter 2 can be made compact,
The package itself can be miniaturized, making it extremely convenient for packaging or carrying.

Furthermore, the most advantageous aspect of the invention is that, in addition to the above-mentioned packaging advantages, the coffee powder and the filter for the coffee powder are integrated into the packaging bag, making it extremely convenient and hygienic to use. It's about getting coffee.

That is, as mentioned above, the package of the present invention has excellent storage stability and is convenient to carry; however, since the package encloses the coffee powder 3 in the filter 2, By opening the package 1, pulling out the filter 2, placing the filter in a suitable container 6 such as a coffee cup, and pouring boiling water, coffee liquid can be extracted immediately. 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 all 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 approximately at right angles 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-mentioned FIGS. 7 to 9 are explanatory diagrams showing an example in which the bending line 9 formed on the support plate 4 is selected to correspond to the difference in the diameter of the coffee cup 17, and can be used for cups with different diameters. 7 shows the case where it is bent along the innermost bending line 9a, and FIG. 8 shows the case where the bent support leg pieces 10, 10 are erected along the outer bending line 9C. Furthermore, in FIG.
This figure shows the case where the supporting leg pieces 10, 10 are bent little by little along the outer bending line 9c'fc to form an arcuate curved surface. In particular, FIG. 9 shows an effective bending method for a cup in which the edge of the cup opens outward.

The supporting leg pieces 10 , 10 erected in this way are inserted inside the edge of the inner leg 18 by using the notches 12 , 12 formed on their edges, and then the two outer legs 19 .
It is fixed to the edge of the cup by bringing it out of the cup and holding it from both sides at 19'.

In this case, since the bending line 9 is formed into an arcuate curve as described above, the supporting leg pieces 10, 10' (
i: When you stand up, it automatically bends, giving you a firm and firm stance. In addition, in this embodiment, since both ends of the filter paper bag 5 are pasted over the back surface of the support leg pieces, when the support leg pieces are bent and stood up, the two ends come together, making it difficult to close the bag properly. The opening of the filter paper bag 5 is automatically opened,
This will make it easier to pour boiling water.

Note that FIGS. 10 to 12 show modified examples of the notch 12 explained in the above embodiment, and both support leg pieces 1
A U-shaped notch 21 is provided near the edge of the coffee cup 17, and 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 this engagement piece 22 and the edge. This is another embodiment in which a supporting leg piece 10 is erected on top.

That is, in this embodiment, instead of the two notches 812k formed at the leg ends of the supporting leg pieces 10, one U-shaped notch s is provided to form one tongue corresponding to the inner pieces 18, 18. A shaped engagement piece 22 is provided, and at the same time an outer piece 19.1 is provided.
The end i+20 is left as a piece corresponding to 9VC, and the outer pieces 19 and 19, which were separate so to speak, are formed in a completely continuous state and opposed to the inner piece, the engaging piece 22. Nishi'f1. ．． In this case, both pieces are the 11th
, as shown in Figure 12, the tongue-shaped engagement piece 22 and the circular piece 1
Similar to step 8, insert the green inside of the cup and insert the other edge 2.
0) Similar to 9, the supporting leg pieces can be placed on the outside of the cup and clamped from the inside and outside, and can be stably fixed upright on the entire cup.

As mentioned above, the filter can be easily assembled and placed on the cup on its own, and the coffee liquid is extracted by simply pouring hot water into the cup, making it extremely difficult to handle. It is easily done. In this case, the filter stands up on top of the cup, and the inside of the filter paper bag and cup can be seen through between the supporting legs, making it convenient to monitor the state of coffee extraction. Since the coffee powder is sealed in advance, it does not come into contact with hands and can therefore be disposed of hygienically. On the other hand, the coffee powder can be measured in advance and kept constant according to the number of people in the cup used. By specifying the amount of hot water and determining the pouring amount, it is possible to automatically keep the coffee concentration constant, and there is an advantage 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 completely airtight, for example, a synthetic resin film or a composite film made of a synthetic resin film fully laminated with aluminum foil is suitable. In addition, when this type of film is used, heat sealing is possible, which facilitates the sealing work.

Further, in the embodiment described above, a substantially circular annular cutting line 6 is formed at the center of the support plate 4 of the filter, and a lid 8 for closing this opening is integrally provided. Although the opening is assumed to be closed when in the sealed state, if the opening is closed when folded like the filter paper bag 5 described above, this lid may not be completely closed.

Of course, the lid part 8 is not limited to being cut out from the support plate 4, but may be formed of a separate film and placed over the opening to close it so that it can be easily removed. It's not even a trench.

Further, in the above embodiment, all the bending lines 9, 9 were provided when forming the supporting leg pieces on the support plate 4 of the filter, but as is clear from the explanation, these bending lines make the supporting leg pieces stand up. This serves as a reference point and a guideline.When carrying out the work, make perforations, make shallow cut lines on the surface of the support plate, or crush and shape it with a press to form the mold.
