Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a container-shaped simple strainer for extracting a preferred beverage such as coffee from fine powder, and more specifically, a container-shaped strainer capable of containing fine powder of a preferred beverage such as coffee. This relates to a simple strainer.

Conventionally, to easily brew coffee, as shown in Figure 1, a plastic container (dripper) a with many small holes in the bottom was lined with filter paper 3', and fine coffee powder was poured on top of the filter paper 3'. This was done in a so-called drip format, in which hot water was poured over the cup and the extracted coffee was dripped into the coffee cup B.

However, with such a drip type, not only a plastic container (dripper) a is required, but also the residue of fine coffee powder must be thrown away together with the filter paper 3' after the extraction is finished. , and plastic containers (
There was a drawback that the dripper (a) had to be cleaned and it was troublesome to brew coffee.

The present invention has been made in view of these conventional drawbacks, and its purpose is to make the container itself disposable, eliminate the hassle of pouring coffee, etc. In the present invention, due to the rational structure of the container, it is possible to easily seal one serving of finely powdered beverages such as coffee in a pack form while keeping the container airtight. In such cases, the pack container can be used as a strainer as it is, and it is not only easy to handle, but also convenient to carry and use for medicines and other beverages such as coffee. The object of the present invention is to provide a simple container-shaped strainer for extracting from fine powder.

An embodiment of the present invention will be described in detail below with reference to the drawings.

Reference numeral 1 denotes a sheet material, which is made by laminating a thermoplastic synthetic resin 1b such as polyethylene on the entire back side of a paper 1a having enough rigidity to maintain its shape when folded.

The sheet material 1 is cut into a rectangular shape.

Although this cutting step is performed at the end of the manufacturing process described below, it may also be performed at the beginning of the process.

These two sheet materials 1 and 1 are made of thermoplastic synthetic resin 1.
Both side edges of the sheet materials 1 and 10 are heat-sealed over the entire length of the sheet materials 1 and 10 with their b sides facing each other.

The heat-sealed portion serves as the connection portion 4.

The sheet material 10 paper 1a has vertical fold lines 2 formed therein so that the sheet material 1 can be folded outward.

Vertical folds 2 are placed at positions that approximately divide the sheet material 1 into three equal parts in the width direction.
This is the actual setting.

The number of vertical folds 2 may be more or less than this.

By holding the connecting parts 4, 4 of the two sheet materials 1, 1 with your fingers and bringing them close together, each sheet material 1 is folded outward to form a polygonal rectangular tube shape. It is.

Note that the sheet material 1 may be one in which thermoplastic synthetic resin 1b is laminated on the back side of aluminum foil, or may be one in which thermoplastic synthetic resin is laminated on a synthetic resin sheet, or it may be composed only of a thermoplastic synthetic resin sheet. You can.

Then, a filter paper 3 that can close the square tube-shaped bottom opening formed by the two sheet materials 1, 1 by bringing the side edges of the two stacked sheet materials 1, 10 close to each other is attached to two sheets. It is provided so that it can be folded freely between the materials 1 and 1.

Furthermore, as shown in FIG. 3, between the two sheet materials 1 and 1,
Fine coffee powder C for one person is filled, and the entire periphery of the two sheet materials 1, 1 is heat-sealed to keep the fine coffee powder C airtight and sealed.

In addition, there is a connection part 4 that spans the entire length of the upper and lower parts of the two sheet materials 1, 1.
A large number of cross-cuts 12 are provided at vertical intervals.

The attachment structure of the filter paper 3 and the sealing structure of the fine coffee powder will be explained below according to the steps.

As shown in FIG. 4, the long filter paper 3 is bent into a W-shape.

The filter paper 3 includes a thermoplastic synthetic resin such as polyethylene in the form of single fibers, and is heat-sealable.

The length of the upper edge and both ends in the length direction shown by the hatched part 5a of the back side piece 5 in FIG. 4 of the W-shape of the filter paper 3, and the lower edge of the side piece 5 (not shown). The center portion in the width direction is heat-sealed to the shaded portion 1c of the sheet material 1 on the back side in FIG.

Then, the portion 6a of the W-shaped front side piece 6 in FIG. 4 surrounded by the dotted line is heat-sealed to the portion 1d of the front sheet material 10 surrounded by the dotted line in FIG.

Note that the process of heat sealing the back side piece 5 to the back side sheet material 1 and the process of heat sealing the front side piece 6 to the front sheet material 1 may be performed at the same time, or they may be performed at different times. good.

Through this process, as shown in FIG.
A long W-shaped filter paper 3 is heat-sealed between two sheets of sheet material 1, 1.

In the heat-sealing process shown in FIG. 4, both longitudinal ends of the unit-length filter paper 3 do not need to be heat-sealed to the sheet material 1 on the back side and the sheet material 1 on the front side.

Next, as shown in FIG. 5, the edge portions and bottom portions of both sheet materials 1 and 10 shown by the diagonal line portion 1e and broken line portion 1f of the sheet material 1 on the back side and the sheet material 1 on the front side are heated. It is sealed to form a bag, and cut along the cutting line 7 to obtain a bag.

In such a case, the filter paper 3 is heat-sealed below the lowest end, and the filter paper 3 will not be torn even if it is cut with fingers or the like above the heat-sealed portion.

Next, the inside of the bag-shaped body is filled with one person's worth of fine coffee powder C, and then the X-ray parts 1g of the sheet material 1 on the back side and the sheet material 1 on the front side are heat-sealed to form a bag-shaped body. The upper opening of the body is closed to obtain a package 3 in which one serving of fine coffee powder C is airtightly packaged, as shown in FIGS. 2 and 3.

In the figure, numerals 9 and 9 are broken lines for breaking and opening.

According to such a configuration, the broken lines 9 and 9 between the upper and lower edges of the package 8 shown in FIG. It is made into a rectangular cylinder shape, and appropriate cross-cuts 12 are cut with fingers according to the depth of the coffee cup b, and the cut cross-cuts 12 are cut as shown in FIG.
Fold the lower part of the package 8 into a coffee cup b.
Put it inside with it raised up from the bottom and make the crosscut 12.
Place the lower rim 13 on the rim of the coffee cup b, pour boiling water from the boiler 11 into the upper opening 10 of the package 8, and drip the extracted coffee into the coffee cup b to brew coffee using a drip type method. It is.

At this time, the package 8 can be held largely lifted from the bottom of the coffee cup b without having to hold it by hand.

FIG. 14 shows yet another embodiment, in which a notch 15 is formed at the lower edge of the two sheet materials 1 so that convection can occur in the coffee cup b through the notch 15. This allows for more effective diffusion of coffee extract.

FIG. 15 shows still another embodiment of the same as above, in which a bag-like body is obtained by heat-sealing a side piece of a W-shaped filter paper 3 to a hatched portion 10' shown over the entire length of the sheet material 1. be.

In the examples, fine coffee powder is used, but black tea, tea, etc. may also be used instead.

Black tea, etc., is not a drip type like coffee, but is extracted by immersing the filter paper 3 and its vicinity in hot water.

In summary, the present invention involves connecting two moderately rigid sheet materials by pasting their edges on both sides, providing vertical folds in each of the sheet materials to allow the sheet materials to be folded outward, and stacking them together. A filter paper that can be folded freely between the two sheet materials can close the bottom opening of the rectangular tube formed by the two sheet materials by bringing the side edges of the two sheet materials close to each other. Therefore, the two edges of the two sheets are connected, and the bottom openings of the two sheets are closed with a foldable filter paper, so the two sheets are overlapped. This allows the sheets to be folded thinly, and since each sheet has vertical folds that allow the sheet to be folded outward, the edges on both sides of the two stacked sheets can be easily folded. By bringing the sheets closer together, each sheet material can be easily folded outward through the vertical folds, and the whole can be conspicuously shaped as a polygonal cylindrical container with a bottom. The shape of the polygonal cylindrical shape can be changed over the range from the folded state to when a part of the filter paper is expanded, and this makes it possible to cope with changes in the diameter of the coffee cup, regardless of the size of the coffee cup. For example, it has the advantage of being able to make drip-type coffee without having to worry about it.

Moreover, especially in the present invention, since the filter paper is foldably attached between the bottoms of the two sheet materials,
By filling the gap between two sheet materials with one person's worth of fine powder, such as coffee, and sealing the upper and lower openings of the two sheet materials, one person's worth of coffee can be made. The fine powder can be packed in a pack, and with this configuration, the packed container can be used as a filter.To add coffee, etc., you can tear the pack container and add boiling water to it. It is extremely easy to add coffee, etc. just by pouring it in, and by making it disposable, it is even more simple and portable, making it easy to add coffee, etc. even outdoors. It has the advantage of being possible.

In addition, since we provided multiple cross-cuts at intervals vertically at the connection part that spans the entire length of both sides of the two sheet materials,
It is possible to cut an appropriate cross-cut, bend the lower part of the cut cross-cut, and place the lower edge of the cross-cut on the rim of the cup, so that the cup can be lifted from the bottom of the cup without having to hold it by hand. It is easy to use because it can be held securely, and the bent portion below the cut cross-slice of the connecting portion elastically contacts the inner surface of the cup due to elastic restoring force, making it even more stable to hold in the cup. Furthermore, by selecting the crosscut to be cut depending on the depth of the cup, etc., it is possible to hold the cup in a state appropriate to the cup.
