Description

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 and the like. More specifically, a handle and a small handle integrated with a handle holding portion attached to the side surface of the coffee bag. Is a bag for extraction of personal or multi-person preference beverages, etc., which can be held in a stable form over the edge of a cup or a server.

[0002]

2. Description of the Related Art Conventionally, a coffee drip method has been widely used, and recently, a paper drip method has been most frequently used. However, leakage of fine particles and fats and oils is likely to occur, and many attempts have been disclosed regarding the shape and material of the bag in order to enhance the extractability.

For example, Japanese Utility Model Laid-Open No. 55-123480 discloses a filter having a shape in which a handle is attached to a filter and the filter can be hung on the edge of a cup or the like, and disclosed in JP-A-3-210214 and 3-218711. There is disclosed a filter in which a handle having a notch is provided on the side surface of the filter so that the filter can be extracted while hanging on the edge of the cup for a long time. However, when the filter is used with its upper end opened, the filter tends to become unstable.

When the coffee bag is opened by pouring hot water and brewing the coffee by the drip method, the bag swells when the hot water is poured, but the side of the bag is deformed due to the handle holding portion attached to the side of the bag. There was a tendency that the coffee could not be sufficiently swelled because it was suppressed, and coffee extraction was hindered.

There are many problems when used for extracting tea, green tea, seasonings, etc. in addition to coffee, and there is room for improvement.

[0006]

DISCLOSURE OF THE INVENTION According to the present invention, when coffee, tea, seasonings or the like is to be extracted, a handle and a small handle which are integrated with a handle holding portion are provided on the side surface of the bag, and the handle or small handle is attached to the edge of the cup or the server. Hold it in a stable state, and make it easier to swell the bag so that the contents such as coffee powder can be sufficiently extracted, and if necessary, when opening the upper part of the bag, there is no fray of the cut edge, and a clean linear shape It seeks to provide an extraction bag that can be opened.

[0007]

[Means for Solving the Problems] When the present inventors use a bag for extraction containing a palatable beverage such as coffee or a seasoning to extract the palatable beverage or seasoning, a handle is provided on the side surface of the bag. When the handle and the small handle that are integrated with the holder are attached and the two handles are crossed and hung on the edge of the cup or server, the form becomes extremely stable, and holding this state for a long time improves the extraction efficiency. I found that

Further, in the case of adding coffee etc. by the drip method, when opening the upper part of the bag and pouring hot water, paying attention to the fact that the hot water easily spills from the bag when the open part is frayed. If the lines of the above perforations are put in parallel and the positions of the parallel perforations are staggered, the bag can be easily opened without fraying the cut edges, resulting in the present invention. Arrived

That is, the bag 1 and the handle holding portion 2 attached to the surface of the bag 1 are formed. The bag is made of a flexible sheet having filterability, and at least two handle holding portions are made of a flexible sheet. A handle 3 and a small handle 5 which are attached to the upper part of the holder at a symmetrical position, are hollowed out inside the holding part, leaving a part of the sheet of the holding part, and are connected to the holding part at the cut-out part. The handle 3 has a shape in which a notch 4 opened downward is formed between the handle 3 and the holding portion when the handle 3 is raised, and a notch 6 opened downward is provided in the small handle 5, and if necessary, a further smaller handle is provided. A bag 7 for extracting a favorite beverage or seasoning, which is provided with a protrusion 7 on the upper part and which is hung on a rim of a cup or a server by raising a handle and a small handle, and further, a handle holding portion and a connecting portion 7 of the handle and the small handle. , If desired, one or a plurality of cuts having an uncut portion in the vertical direction of the other portion of the handle holding portion or a palatable beverage or seasoning provided with at least one perforation in those portions It is an extraction bag.

The term "symmetrical" as used herein includes not only strictly geometrical symmetry but also positions and shapes that are considered to be approximately symmetric. Further, the perforation line usually means a shape in which a sheet is intermittently cut, but in the present invention, a part between the cuts is also cut, and the sheet is thinner than the normal thickness. It also includes a thin cut state. The present invention will be described in detail below.

In the present invention, the palatable beverages include coffee, cocoa, black tea, oolong tea, green tea, barley tea, kelp tea,
Soup and the like, and seasonings widely include bonito flakes, shiitake mushrooms, dashi kelp, and dried sardines.

The extraction bag of the present invention needs to be made of a flexible sheet having filterability, and its material is not particularly limited as long as it is woven fabric, knitted fabric, non-woven fabric, paper or a composite material thereof. Can be widely used. There are subtle differences in filterability depending on the material and structure of the bag, which may affect the flavor of the palatable beverage obtained. For example, the most important properties required of the filter for making coffee with an excellent aroma and rich taste are that the coffee fine particles do not leak into the liquid and that the oils and fats contained in the coffee liquid are absorbed. It is necessary to remove so that the oil film does not float on the surface of the cup. All of these are factors that significantly hinder the taste of coffee, and if fine particles are mixed in, the texture will be unpleasant, and if oils and fats float on the surface of the cup, it will be glaring, which is not preferred.

The material of the extraction sheet used in the present invention is not particularly limited, and a wide range of filter cloths can be used,
A non-woven fabric containing ultrafine fibers having a fineness of about 0.2 denier or less is known as a material for preventing leakage of fine particles and enhancing oil and fat adsorption. Therefore, such a material can be used for the bag of the present invention. Such ultrafine fibers are produced from a thermoplastic polymer by, for example, a melt blow method. Types of thermoplastic polymers include polypropylene and polyethylene. Further, by using a composite non-woven fabric of such a non-woven fabric layer of ultrafine fibers and a support layer composed of fibers of ordinary thickness, the filterability and the mechanical properties of the filter fabric can be further improved.

Further, the handle holding portion and the handle must be made of a sheet having a waist. The stiff sheet refers to a property that the sheet has a hardness such that the sheet is not deformed even when a small external force is applied, and is, for example, a slightly thick paper or a plastic sheet. 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.

At least two handle holders must be attached at symmetrical positions on the bag. In the case of a large bag, a mode in which three or more handle holding portions are attached can be used.

The handle holding portion is provided with a handle and a small handle,
The handle and the small handle are hollowed out by leaving a part of the sheet of the handle holding portion, and are held by being connected to the holding portion by the uncut portions 12, 12'13, 13 '. Alternatively, the connecting portion between the handle and the small handle and the handle holding portion may be connected via a perforation or a fold.

The handle holding portion is attached to the bag by means of fusion, adhesion or other means, and since the handle and small handle portions are not adhered to the surface of the bag, the handle holding portion is attached as shown in each figure of the embodiment. When it is raised, it becomes a handle, and the handle and the small handle are shaped so as to be arranged at opposite positions. The raised handles and small handles are preferably crossed, for example, a downwardly open notch 4 formed between the handles and the handle holder, for example at the edge of a cup or server.
Also, the bag can be held by making a cut 6 opened downward on the handle.

If necessary, a projection 7 can be provided on the upper portion of the small handle 5. The protrusion 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 a 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 forms a shape in which the two handles are engaged with each other. Therefore, it is structurally more stable. It is possible to use the two handles crossed without the projection 7, or the handles and the small handles may be separately hung on the edges of the cup or the like without crossing.

The handle is normally hollowed out except for the part connected to the handle holding part when it is raised, but it is provided with a small part of a dot-like uncut portion, and it is kept inside the handle holding part until it is used. The present invention also includes the case where it can be held in the housed state. For example, 14 and 14 'in FIG.
It is the state shown in.

When the handle is raised, it is necessary to have a shape such that a notch 4 opened downward is formed between the handle and the handle holding portion. This notch is preferably used, along with the notch 6 which is open to the lower part of the grip crossing the grip, to hold the bag over the edge of a cup or server or the like. For example, when dripping coffee, when hanging the bag on the edge of the cup or server,
It can be held in a more stable form. The shape formed between the handle and the holding portion and the notch provided in the small handle may be a shape that opens downward, and are not particularly limited, but are, for example, as shown in FIG.

According to the present invention, the connecting portions 8 and 9 of the grip holding portion and the grips and the small grips, and optionally other portions of the grip holding portion, for example, the vertical direction of the intermediate portion 10 of the grip holding portion,
A cut line having one or a plurality of uncut portions, or an aspect in which at least one perforation line is provided in those cut lines is also included. By providing such cuts or perforations in the handle holding part that is adhered to the bag,
It makes it easier to raise the handle during use, and when the bag is hung on the edge of the cup or server due to the flexibility of the handle holding part, the outside of the bag bends along the edge of the server, so it fits better on the server. And easy to handle. Further, it is preferable that 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, the bag easily inflates, for example, when coffee is extracted from coffee powder by a drip method. Can be sufficiently extracted.

The brewing bag of the present invention can be filled with the contents and then sealed at the upper end and opened at the time of use so that hot water can be poured into the brewing bag for extraction, or the bag is always used in an open state. It is also possible to add contents such as coffee powder as needed and inject hot water for extraction.

When the upper end 11 is sealed after the contents are enclosed, at least two parallel perforation lines 15 and 15 'for opening the bag are provided on the upper part of the bag, and the perforation lines are parallel. It is necessary to stagger the positions of. This is because when you use a bag with contents enclosed, you cut the bag from the perforation line with your fingers to open it, but there are multiple perforation lines and the positions of adjacent perforations are staggered. Then, even when the cut line deviates from the perforation line, it easily moves to the adjacent perforation line, so that the cut does not become a frayed shape. Therefore, since the cut end is clean, the poured hot water does not spill and is easy to use.
At this time, it is more preferable that the number of perforations and the distance between the perforations are arranged differently on the front and back sides of the bag so that the cut edges will not be frayed even if the sheets are sealed in a slightly displaced state.

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

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