DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag for extracting coffee, tea, seasonings, etc. More specifically, a handle and a small handle integrated with a handle holder attached to the side of a coffee bag. Is an extraction bag for a personal or multi-person favorite beverage or the like that can be held in a stable form over the edge of a cup or server.

[0002]

2. Description of the Related Art Conventionally, there are many coffee extraction methods using a drip method, and recently, a paper drip method has been used most often. However, many attempts have been made on the shape and material of the bag in order to easily extract fine particles and oils and fats, and to improve the extractability.

For example, Japanese Utility Model Laid-Open No. 55-123480 discloses a filter having a shape that can be extracted by attaching a handle to the filter and hanging it on a rim of a cup or the like, and Japanese Patent Application Laid-Open Nos. 3-210214 and 3-218711. There is disclosed a filter in which a handle with a notch is provided on the side of the filter and can be extracted while being hung on the edge of the cup for a long time. However, when the filter is used with the upper end opened, the filter tends to be unstable.

In addition, when hot water is poured by opening the upper part of the coffee bag and coffee is extracted by the drip method, when the hot water is poured, the bag expands. However, the side of the bag is deformed due to the handle holding portion attached to the side of the bag. It was suppressed and could not swell sufficiently, and the extraction of coffee tended to be hindered.

[0005] In addition to coffee, there are many problems when used for extraction of black tea, green tea, seasonings and the like, and there is still room for improvement.

[0006]

SUMMARY OF THE INVENTION In the present invention, when extracting coffee, tea, or seasonings, a handle and a small handle integrated with a handle holding portion are provided on the side of a bag, and the bag or server is wrapped around the edge of the cup or server. Hold it in a stable state, and furthermore, the bag easily swells so that the contents such as coffee powder can be sufficiently extracted, and if necessary, when opening the top of the bag, there is no fraying of the cut edge and a clean line It is intended to provide an extraction bag that can be opened.

[0007]

SUMMARY OF THE INVENTION The present inventors have found that when a palatable beverage or a seasoning is extracted using an extraction bag containing a palatable beverage such as coffee or a seasoning, a handle is provided on the side of the bag. When the handle and the small handle integrated with the holding part are attached, when the two handles are crossed and hung on the edge of the cup or the server, the form becomes extremely stable, and by holding in this state for a long time, the extraction efficiency is enhanced. Was found to be.

In addition, when pouring hot water into the upper part of the bag when pouring coffee or the like in a drip method, paying attention to the fact that hot water is easily spilled from the bag if the opened part is frayed. If the lines of the above perforations are inserted in parallel and the positions of the parallel perforations are alternated, it is possible to easily open the bag without fraying the cut edge. Reached.

More specifically, the bag comprises a bag 1 and a handle holder 2 attached to the surface of the bag. The bag is made of a flexible sheet having a filtering property. At least two handle holders are made of a waisted sheet. Is attached at a symmetrical position on the upper part of the holding part, and the inside of the holding part is cut out while leaving a part of the sheet of the holding part, and a handle 3 and a small handle 5 connected to the holding part at the uncut part are provided. The handle 3 has a shape in which a notch 4 opened downward is formed between the handle 3 and the holding portion, and a notch 6 opened downward is provided in the small handle 5. A bag 7 for palatable beverage or condiment extraction, which is provided with a protrusion 7 at the top and raised and crossed over the edge of the cup or server by raising and crossing the handle and small handle; A palatable beverage or condiment comprising, if necessary, one or more cuts having an uncut portion or at least one perforation in those portions in the vertical direction of other portions of the handle holding portion. This is an extraction bag.

Here, the term "symmetrical" includes not only strictly geometrical symmetry but also a position and a shape which are considered to be approximately symmetrical. In addition, the perforation line usually refers to a shape in which the sheet is intermittently cut, but in the present invention, a part between the cuts is also partially cut, which is more than the normal thickness of the sheet. The thinned cut state is also included. Hereinafter, the present invention will be described in detail.

In the present invention, the palatable beverage includes coffee, cocoa, black tea, oolong tea, green tea, barley tea, kelp tea,
It is a soup, and the seasonings include bonito, shiitake mushroom, dashi kombu, and boiled dried.

[0012] The extraction bag of the present invention must be made of a flexible sheet having a filtering property, and the material is not particularly limited. If it is a woven fabric, a knitted fabric, a nonwoven fabric, a paper or a composite material thereof, Can be used widely. There is a slight difference in filterability depending on the material and the structure of the bag, which may affect the flavor of the obtained palatable beverage. For example, in order to put coffee with excellent aroma and richness, the most important properties required of the filter are that the coffee fine particles do not leak into the liquid and absorb the oils and fats contained in the coffee liquid It is necessary to remove it so that the oil film does not float on the surface of the cup. All of these are elements that significantly impair the taste of coffee, and if mixed with fine particles, it feels unpleasant to the touch, and if oils or fats float on the surface of the cup, they are not preferred.

The material of the sheet for extraction used in the present invention is not particularly limited, and a wide range of filter cloths can be used.
As a material for preventing the leakage of fine particles and for enhancing the adsorptivity of fats and oils, a nonwoven fabric containing ultrafine fibers having a fineness of about 0.2 denier or less is known. Therefore, such a material can be used for the bag of the present invention. Such ultra-fine fibers are manufactured from a thermoplastic polymer by, for example, a melt blow method. Examples of the type of the thermoplastic polymer include polypropylene and polyethylene. In addition, by using a composite nonwoven fabric of such a nonwoven fabric layer of ultra-fine fibers and a support layer made of a fiber having a normal thickness, the filterability and the mechanical properties of the filter cloth can be further improved.

Further, the handle holding portion and the handle need to be made of a seat having a waist. A stiff sheet refers to a property having such a hardness that the sheet is not deformed even when a small external force is applied, and is, for example, a paper or a plastic sheet having a little thickness. Further, since the handle holding portion is usually used in a state of being immersed in hot water, a material having water resistance is preferable.

It is necessary to attach at least two handle holders at symmetric positions of the bag. In the case of a large bag, a mode in which three or more handle holders are attached can be used.

A handle and a small handle are provided in the handle holding portion.
The handle and the small handle are cut out while leaving a part of the sheet of the handle holding portion, and are connected to and held by the holding portion at the uncut portions 12, 12'13, and 13 '. Alternatively, the connecting portion between the handle and the small handle and the handle holding portion may be connected through a perforation or a fold.

The handle holding portion is attached to the bag by fusing, bonding or other means, and the handle and the small handle are not bonded to the bag surface. When it is raised, it becomes a handle, and the handle and the small handle are shaped so as to be placed at opposite positions. The raised handles and small handles are preferably crossed, such as in the edge of a cup or server, for example, a downwardly open cut 4 formed between the handles and the handle holder.
In addition, the bag can be held by hanging a notch 6 opened downward provided on the small handle.

A protrusion 7 can be provided on the upper part of the small handle 5 if necessary. The projection 7 is preferably provided by hollowing out a part of the handle holding portion. When the handle and the small handle are hung on the edge of the cup or the like, if the protrusion 7 is provided on the upper part of the small handle 5, when the handle and the small handle are crossed, the protrusion 7 is formed into a shape in which the two handles are engaged. Therefore, the structure is more stabilized. Even if there is no projection 7, two handles can be crossed and used. Alternatively, the handle and the small handle may be separately hung on an edge of a cup or the like without being crossed.

The handle is usually hollowed out except for the portion connected to the handle holding portion when raised, but a very small point-shaped uncut portion is provided, and the handle is kept inside the handle holding portion until use. The present invention includes a case where it can be held in a housed state. For example, 14 and 14 'in FIG.
This is the state shown in FIG.

The handle must be shaped so that when it is raised, a notch 4 that opens downward is formed between the handle and the handle holder. This cut is used to hold the bag over a cup or server lip or the like, preferably with a cut 6 opened below the handle, crossed with the handle. For example, when putting coffee in a drip method, when putting a bag on the edge of a cup or server,
Can be held in a more stable form. The shape formed between the handle and the holding portion and the cut provided in the small handle may be any shape as long as it is open downward, and is not particularly limited, and is, for example, as shown in FIG.

In the present invention, the connecting portions 8 and 9 of the handle holding portion and the handle and the small handle and, if necessary, other portions of the handle holding portion, for example, in the vertical direction of the intermediate portion 10 of the handle holding portion,
Also included are cuts having one or more uncut portions, or embodiments in which at least one perforation is provided in those portions. By providing such a cut or perforation in the handle holding part adhered to the bag,
This makes it easier to raise the handle during use, and increases the flexibility of the handle holder, so that when the bag is hung on the cup or the edge of the server, the outside of the bag bends along the edge of the server, making it more fit to the server. Easy to handle. Preferably, the cuts or perforations are symmetrically arranged on the back side of the bag.

If a bag made of the above-mentioned material, a handle holding portion, and an extraction bag having a handle are used, for example, when coffee is extracted from coffee powder by a drip method, the bag is easily inflated and the contents are increased. Can be sufficiently extracted.

[0023] The extraction bag of the present invention can be sealed by sealing the upper end after the contents are enclosed and opened at the time of use, and hot water can be poured from the portion to extract, or the bag can be used with the bag always opened. When necessary, contents such as coffee powder can be appropriately added, and hot water can be injected for extraction.

When the upper end 11 is sealed after the contents are sealed, at least two parallel perforations 15 and 15 'for opening the bag are provided in the upper portion of the bag, and the parallel perforations are provided. Need to be provided alternately. This is because when using a bag with enclosed contents, the bag is opened by cutting the bag from the perforation line with a finger, but there are multiple perforation lines, and the positions of adjacent perforations are staggered. Therefore, even when the cut is deviated from the perforation line, it easily moves to the adjacent perforation line, so that the cut does not have a frayed shape. Therefore, since the cut end is clean, the injected hot water is easy to use without spilling.
At this time, it is more preferable that the number and interval of perforations are arranged differently on the front and back of the bag so that the cut edge is not frayed even if the sheet is sealed in a slightly shifted state.

The extraction bag of the present invention is used for adjusting a favorite beverage or seasoning in a personal cup, a medium-sized pot for several persons, or a large-sized server. Can also be used for large-scale extraction.

Hereinafter, the present invention will be described more specifically with reference to examples.
