DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drip bag for hanging a drip-type coffee by hanging it on a container such as a cup.

[0002]

2. Description of the Related Art Conventionally, a paper drip method has been widely used as a method of brewing coffee so that full-scale coffee can be easily enjoyed. In the paper drip method, usually, coffee for several persons (several cups) is extracted at a time.

On the other hand, in recent years, the number of people living alone has increased, and the number of members of one family has decreased due to the nuclear family and a decrease in the birth rate. Therefore, instead of the conventional paper drip method, which is based on extracting several cups of coffee, disposable one-drip coffee aimed at easily extracting one cup of coffee. (Hereinafter, referred to as drip bags) are on the market in various product forms.

[0004] Drip bags on the market so far can be roughly classified into two types depending on the method of setting them in a cup. One of them is a method of placing a dripper on a cup (hereinafter referred to as a cup-on method).
The other is a method in which a hook attached to a dripper is hooked on a wall of a cup so that the dripper is hooked in the cup (hereinafter, referred to as a cup-in method).

When the cup-on method is compared with the cup-in method, the dripper does not immerse in the coffee liquid extracted into the cup during coffee extraction, as in the case of the original parper drip method, so that the coffee flavor is improved. Components that have an adverse effect can be prevented from being eluted from the coffee powder in the dripper.

There are various types of cup-on type and cup-in type drippers, and the cup-on type dripper includes a plastic dripper formed in a substantially cylindrical shape. In some cases, simply placing the dripper on the upper end completes setting the dripper into the cup. According to the cup-on type dripper, it is extremely easy to set the dripper to the cup. In addition, since the dripper is formed from a molded plastic, the dripper bends and deforms when pouring,
The opening of the dripper is not narrowed or closed when pouring hot water. For this reason, pouring into the dripper is easy. Furthermore, since the dripper does not soak in the extracted coffee liquid, it is easy to clean up the dripper after coffee extraction.

[0007] However, some types of cup-on type drippers require assembling before setting them in a cup, and some of them are difficult to assemble without a manual. Some drippers simply placed on the upper end of the cup and used are not stable because the dripper moves on the cup. Furthermore, since the cup-on type is generally large, there is a problem that the dripper is bulky when stocking it up or discarding it after use.

On the other hand, the cup-in system generally has a simpler structure than the cup-on system. In particular, a bag body made of a sheet made of water-permeable filtration containing coffee powder, and a dripper made of a paper-made hanging member affixed to the side of the bag body to hook the bag body to a cup, It is possible to save resources of the forming material, and it is possible to manufacture at low cost. Also, the dripper itself can be made compact. However, since the dripper is immersed in the coffee liquid in the cup during coffee extraction, it is difficult to obtain the original taste of the paper drip coffee. Further, when the dripper is set back after the coffee is extracted, the dripper is immersed in the hot coffee liquid, which may cause burns.

[0009]

As described above, various cup-on type and cup-in type products are on the market as drip bags, but each has its advantages and disadvantages. A drip bag that combines both advantages, that is, one that has the taste of cup-on coffee and the ease with which it can be set and poured into a cup, and can be manufactured as compact and low-cost as the cup-in method not exist.

[0010] The present invention is to solve the above-mentioned problems of the prior art, and it is possible to obtain the taste of coffee which can be obtained by the original paper drip method, has a simple structure, and has a simple structure. It is extremely easy to set
An object of the present invention is to provide a new drip bag which has a stable shape after being set in a cup and is easy and safe to dispose after extracting coffee.

[0011]

Means for Solving the Problems In order to achieve the above object, the present inventor has proposed a bag body made of a water-permeable filterable sheet material and having an opening at an upper end, and a sheet-like material.
A drip bag comprising a hook member provided on two opposing outer surfaces of the bag body, wherein the hook member has a peripheral portion formed on a peripheral side thereof and an inner side of the peripheral portion. An arm portion formed so as to be able to be raised from the bag body, and a tongue piece portion formed inside the arm portion, the peripheral portion and the arm portion being continuous at one of the upper and lower ends of the arm portion, and the arm The arm portion and the tongue piece portion are continuous with each other at the upper and lower ends of the portion, and either the peripheral edge portion or the tongue piece portion is attached to the outer surface of the bag body. I do.

The drip bag of the present invention comprises a bag body made of a water-permeable filterable sheet material and a hook member provided on the outer surface of the bag body. This hooking member can be easily obtained, for example, by making a specific cut line in a rectangular thin plate material. Therefore, the drip bag of the present invention can save resources of the forming material and can be manufactured at low cost.

[0013] Further, the hooking member is formed with a peripheral edge formed on the peripheral side of the hooking member, an arm portion formed inside the peripheral edge so as to be raised, and formed inside the arm portion. The peripheral portion and the arm portion are continuous at one of the upper and lower ends of the arm portion, and the arm portion and the tongue portion are continuous at the other upper and lower ends of the arm portion. That is, the peripheral portion and the arm portion are continuous at the upper end portion of the arm portion,
At the lower end of the arm, the arm and the tongue are continuous, or at the lower end of the arm, the periphery and the arm are continuous, and at the upper end of the arm, the arm and the tongue are connected. It is continuous. Either the peripheral edge portion or the tongue piece portion is adhered to two opposing outer surfaces of the bag body.

Therefore, when the tongue piece is stuck to the outer surface of the bag body, the arm is raised,
It is also possible to raise the peripheral part and put it on the cup side wall, and when the peripheral part is stuck on the outer surface of the bag body, it is possible to raise the tongue piece together with the arm and put it on the cup side wall Becomes In this case, the bag body
The arm is pulled outward from the two opposing surfaces in opposite directions, and is hung above the center of the cup with the opening at the upper end of the bag body largely widened. Also, since the cup side wall is sandwiched between the peripheral edge or tongue piece and the arm, and the outer surface of the cup side wall is pressed down by the peripheral edge or tongue piece, the drip bag is fixed to the top of the cup in an extremely stable state. You.

Therefore, according to this drip bag, it is possible to stably set the drip bag on the upper portion of the cup by an extremely simple setting method. Further, according to this drip bag, the opening of the bag main body is greatly widened when set in the cup. Therefore, according to this drip bag, pouring can be easily performed at the time of coffee extraction. Also,
Since the drip bag is hung on the upper portion of the cup, the drip bag is still above the level of the extracted coffee liquid even after coffee is extracted. Therefore, it is possible to make delicious coffee similar to the original paper drip method. Further, since the drip bag is not soaked in the extracted coffee liquid after coffee extraction, the drip bag after coffee extraction is easy to dispose of, and there is no danger of burns.

The coffee drip bag of the present invention is obtained by filling the drip bag of the present invention with coffee powder and closing the opening of the bag body. Therefore, according to the coffee drip bag, the consumer can easily, easily and safely put in a delicious coffee simply by opening the upper part, setting the cup in the cup, and pouring the hot water.
