Description

[Detailed explanation of the idea] The present invention relates to a decoction package.

The invention provides a flattened shape for packaging and a stable, three-dimensional expansion that creates a large volume interior that makes the contact between the infusion and the contents of the package better and more effective. To provide an improved infusion package having an improved shape.

In one embodiment of the invention, the infusion package comprises a bag of liquid-permeable material having a stable shape of a large volume containing a three-dimensional interior space containing the substance to be infused; at least one fold 24 for flattening the bag from the large volume stable configuration to a relatively smaller internal volume configuration; a device attached to the bag and for expanding the bag to the large volume stable configuration; and a tensioning device formed in cooperation with. Preferably the bag has a fold that is folded inwardly when in the flattened shape, and the tensioning device is attached to the bag on or near the inner fold, thereby folding the fold outwardly. The bag can be easily opened to enlarge the inside of the bag. Preferably the bag comprises a cylindrical body having a top seam and a bottom seam formed transversely and at least substantially at right angles to each other, and the fold line extends at least substantially at least one of the seams. Formed across at right angles.

The present invention also provides a brewing package comprising a generally tetrahedral shaped bag of liquid permeable material having a creasing device for flattening the bag from its tetrahedral shape. Ideally, the generally tetrahedral bag comprises a cylindrical body, a seam at opposite ends of the cylindrical body, and a creasing device, the creasing device having at least a substantial portion in one of the seams. a pair of folds on one side of the one seam and converging from at or near the ends of the seam to the first fold, and the one seam; and another pair of folds on the other side of the seam converging from at or near the ends of the seam to the first fold.

More specifically, it has an overall tetrahedral shape, has a larger internal volume than a conventional bag of substantially the same height and width, and is less restrictive to the Tei leaf particles during infusion. A tea bag like this will be provided. The bag of the present invention has a larger internal volume than a conventional pillow bag using the same amount of bag material and than a commercially available two-bag bag using a larger amount of bag material. A tetrahedral shape is not suitable for ordinary packaging, but by creating creases in the T-bag, it can be crushed into a flat shape, making it possible to package large quantities. A string or plastic strip is attached at or near the fold and can be pulled to expand the bag into a stable three-dimensional shape. Furthermore, when the bag is expanded, air is pre-filled into the extra volume, which prevents the bag from collapsing when immersed in liquid. When immersed, liquid or hot water replaces air.

The tea, which is placed in pieces in a cup or pot containing hot water, is only restrained by the walls of the cup or pot, around which the water can move freely, so that all the tea leaf particles are separated. Virtually the entire surface area participates in the infusion. When the hot water moves, the hot water near the surface of the tea leaves is replaced, making the infusion more effective. In order to make the Tei bug into such a shape, it must have a stable three-dimensional shape that does not constrain the Tei leaves. However, such relatively bulky tea bags require a large amount of space when packaged. The outstanding feature of this invention is that it can be packaged in a way that requires little or no more space than the ordinary flat T-bags currently on the market.
Moreover, it still has a relatively large internal volume suitable for brewing.

The inventive bag increases the extraction rate for decoction. This bag (a) produces faster and more effective infusions, (b) requires less tea per bag, and (c) allows for better infusion from mixed teas, which were previously not sufficient. This allows for a wider selection of tea mixtures. The bag's liquid-permeable material can be reduced by approximately 40% compared to a conventional two-bag tea bag of the same height and width. The bag of the present invention has good filtration flow characteristics, which improves the flow of solids extracted from inside the bag to the liquid outside.

The decoction bags of the present invention can be manufactured using ordinary water-permeable sheets used to make conventional tea bags. So-called "heat seal" T-bag paper is ideal.

The brewing bag of the present invention can contain various kinds of contents. Generally this is soft plant material such as leaves (actually most leaves, plus a proportion of stems and shoots), petals, and flowers from which a beverage can be made. The most commonly used infusion materials are:
Tea plant (Camellia synesis)
sinesis), (L) O. Kunze). Depending on how long the collected tea leaves are fermented until hot by the natural enzymes in the leaves, they become green, black, or oolong tea. A variety of other soft plant materials, such as pine, chamomile, mint, verbien, linden, hibiscus, cherry blossom, camfrey, and alfalfa, are infused throughout the world as recreational drinks and for medicinal purposes. used for a purpose. Furthermore, the invented brewer can also be used to brew ground coffee beans.

Next, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

As seen in FIG. 1, the tea bag assembly 10 includes a bag 12, a plastic strip 13, and a tab 14. Staple 15 for obi and tab
It is fastened by. Band 13 is glued to top seam area 17 as shown in FIG. Alternatively, it may be attached by welding or staples. Also obi 1
3, an ordinary string may be attached to the seam area 17 of the bag by means of staples, if desired. As used herein, the term "tensioning device" refers to a string, elongated thin plastic strip 13, or any other elongate member by which a tea bag can be dipped into and pulled out of a tea cup or pot.

FIG. 2 shows a packet or wrapper 18 enclosing the T-bag 10. As is well known in the art, tab 14 may be a tearable portion of the sidewall of packet 18, with perforations provided in the sidewall of the packet to facilitate tearing.

FIG. 3 shows the generally tetrahedral shape of the bag 12. This is the shape of a pot designed for brewing tea.

The bag 12 is closed at its upper end with a seam area 17 extending laterally across the top or upper end;
and closed at its lower end by another seam area 21 extending laterally across the bottom or lower end;
It has a cylindrical body part. The upper and lower seam areas are not parallel, but intersect each other when viewed from above or below. In particular, in the embodiment shown, the intersection of the seam areas is generally perpendicular. In this particular bag embodiment, the seams are also perpendicular to the axis or longitudinal direction of the body. The side seam 22 forming the tubular body 20 is clearly visible in FIGS. 1, 2, and 3. The material from which the bag 12 is made may be liquid permeable paper or other materials well known in the art. The meaning of the term “generally tetrahedral” is:
Although the tubular body can be made exactly tetrahedral in shape if desired, the body of this bag does not require distinct folds to create four sharp flat sides, and the top seam as shown. This means that a somewhat rounded area may be left between the and bottom seam.

Bug 12 is the crease line 23, 24, 25
It can be made into a flat shape as shown in FIG. Fold line 24 crosses at or near the center of seam 17 and extends generally parallel to lower seam 21 . Fold lines 23 and 25 start from each end of seam 17 on either side of it and converge to a point 24' on fold line 24. The T-bag is folded along these folds to form a packet 1.
8 and placed in a small carton along with many other teabags.

The band 13 is attached to the upper seam area 17 near the central fold 24. The bag 12 then begins to open as it is withdrawn from the packet 18, allowing air to enter the bag. This prevents the bag from collapsing when immersed.

For most effective use, the upper seam area 17 may be pulled into a straight or nearly straight position. This causes the bag to approximate a tetrahedral shape and maintain its stable, extended three-dimensional shape. Line 26 in FIG. 3 indicates the level of dry tea in the erected bag 12. As can be seen from this figure, a large portion of the internal volume of the bag 12 is left free, which not only does not impede expansion of the tee, but also allows for a large amount of slack, resulting in better contact between the liquid and the tee. , a better flow of tea and liquid and therefore better infusion is possible. The tee bag of the present invention can accommodate the tee in less than half the expanded bag volume without increasing its overall height and width over conventional bags. As an actual example, the height of the bag is approximately 57.2mm (21/4") and the width is approximately 38.1mm (11/2")
It is. This is the same height and width as a single tea bag, which is widely sold individually packaged.

It will be appreciated that the decoction package as described herein can be applied to things other than teabags. In summary, this package allows for shorter brewing times, the use of fewer or different contents per package, or the use of a combination of these advantages without compromising the quality of the product. . Also, the volume of the package can be increased with little or no reduction in packaging space.
