Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a pack filled with a drinking material such as tea leaves, bonito flakes, kelp, Chinese herbs, and powdered coffee.

[0002]

In recent years, beverages prepared by filling tea leaves in a water-permeable bag have been increasing in popularity because they do not require special equipment such as tea strainers and can be easily used. When using such drinks, it is common to shake the bag up and down, left and right while the bag filled with tea leaves is immersed in hot water poured into the container in order to extract the components in a short time. . The bag is then removed from the container when the tea has the desired strength.

By the way, the above operation cannot be performed by directly picking the bag with fingers. Therefore, chopsticks and spoons are used for it. However, preparing and putting away such equipment greatly reduces the ease of use. To solve this problem,
It is considered that a bag filled with tea leaves is attached with a thread of about several cm. A typical example thereof is shown in FIG.

In the figure, 21 is a bag filled with tea leaves, 22
Is a thread and 23 is a knob. The thread 22 is for the bag 21,
It is fixed using a U-shaped needle fitting. The same applies to the knob 23. The knob 23 is the bag 21.
It also serves as a part of the packaging material that stores, and is separated from the packaging material when used. As described above, the bag 22 and the thread 22
If you attach it, it will be possible to handle without using chopsticks or spoons, and the above problems will be solved. However, on the other hand, it has the drawback of being considerably expensive.
This is because the process of stopping the thread 22 with the needle fitting is not easy, and at present, it is necessary to rely on manual work.

Although the mechanization of the needle stopping process has been studied, it has not been put to practical use because the device becomes extremely complicated and it is difficult to perform the process by continuous flow work. Therefore, the problem to be solved by the present invention is to provide a drinkable material filling pack which can be easily used without requiring tools such as chopsticks and spoons at the time of drinking and can be manufactured at low cost. .

[0006]

[Means for Solving the Problems] The above-mentioned problems are solved by a bag body made of a sheet material having water permeability and filled with a drinking material, and a string body attached between two points on the surface of the bag body. And a drinkable material filling pack comprising:

In order to simplify the manufacturing work, a bag body is formed by folding one end side of a sheet material to the other opposite side and closing the side adjacent to the folded side. It is preferable that the cord body is further attached between two side edge portions formed by closing the cord body. Also,
It is preferable that the cord body is a band made of a non-woven fabric. Along with this, if the bag body is also made of a non-woven fabric, the cord body and the bag body can be easily joined by heat fusion.

It is preferable to simultaneously perform the sealing on the tip side of the (N + 1) th drinking material filling pack connected to the drinking pack. The bag-filled drinkable material filling pack is separated from the seal portion, but the seal portion here does not necessarily mean only the joint portion between the bag body and the string material, and the bag body. It means the joint with the cord and its vicinity. For example, in two adjacent packs for filling a drinkable material, the rear end of the one located upstream in the carrying direction and the tip of the one located downstream in the carrying direction may be sealed at different positions. In this case,
The seal portions are separated from each other, that is, the portion where the bag body and the cord material are not directly joined.

As described above, the drinkable material filling pack of the present invention is characterized in that the cord body is attached between two points on the surface of the bag body, particularly between two opposing side edge portions.
Therefore, when using it, one of the ends of the string can be cut off from the bag, and the end on this side can be picked up with your fingers to remove the need for utensils such as chopsticks and spoons even when immersed in hot water. Can handle the bag. In other words, the operation of rocking the bag body vertically and horizontally can be performed while the bag body is immersed in hot water poured into the container. Similarly, the bag body can be taken out from the container by pinching the cord body. Therefore, it is not necessary to prepare or put away the tools, and the tools can be used easily without any trouble.

In addition to these effects, the drink material filling pack having the above-described structure has a feature that it can be provided at a low cost. This is because the manufacturing thereof is significantly easier than the conventional one. In other words, mass production can be performed using the above-mentioned manufacturing technique, so that the cost of the drink material filling pack can be reduced. More specifically, the pack for filling a drinkable material of the present invention is obtained by folding a sheet material into a tubular shape, stacking the tubular body thus obtained and a string material, and further front and rear ends of the tubular body along the conveying direction.

BEST MODE FOR CARRYING OUT THE INVENTION A drinkable material filling pack of the present invention comprises a bag body made of a sheet material having water permeability and filled with a drinkable material, and between two points on the surface of the bag body (particularly, facing each other). And a cord body attached between the two side edges). Hereinafter, the pack for filling a drinking material will be specifically described with reference to FIGS. 1 to 4. 1 is a perspective view of the pack for filling the drinking material with the contents filled therein, FIG. 2 is a perspective view showing the folded state of the non-woven sheet constituting the bag body, and FIG. 3 is a state in which the contents are filled. FIG. 4 is a cross-sectional view of the drinking material filling pack in FIG. 4, and FIG. 4 is a cross-sectional view showing a usage state of the drinking material filling pack.

In each figure, reference numeral 1 denotes a bag which can be said to be the main body of a pack for filling a drinkable material, in which tea leaves, bonito flakes,
Drinking materials such as kelp, Chinese herbs, and coffee powder are filled and enclosed. The bag body 1 is made of a material having water resistance and water permeability, for example, a nonwoven fabric sheet. The structure will be described below with reference to FIG.

The bag body 1 is formed by folding a nonwoven fabric sheet as shown in FIG. In particular, the folding piece 2 is formed by bending the end portion on the side indicated by (α) in FIG. On the other hand, a folded piece 3 having a V-shaped cross section is formed on the side indicated by (β) in the figure by double bending the end side. The folded piece 2 fits in the valley of the folded piece 3 as indicated by an arrow, and the nonwoven fabric sheet becomes a tubular body. Then, the side adjacent to the folded side (indicated by a mesh line in FIG. 2), that is, the left and right side edge portions 4a and 4b are closed by heat fusion to form the bag body 1.

With this structure, the opening of the bag body 1 can be formed by overlapping the folded piece 2 and the folded piece 3. Since the folded piece 2 and the folded piece 3 are usually in close contact with each other,
The opening is in a closed state. When filling the inside of the bag 1 with a drinkable material such as tea leaves, a force in the opposite direction is applied to each of the folding pieces 2 and 3 to force them to separate. As a result, the folded pieces 2 and 3 are disengaged from each other, and an opening leading to the inside appears.

On the contrary, when closing the opening of the bag body 1, the side edge portions 4a and 4b may be strongly pulled in the left-right direction, whereby the folding piece 2 is again locked by the folding piece 2. , Sealed so that the contents do not leak out. FIG. 3 shows a state where the bag 1 is filled with a drinking material such as tea leaves by the above procedure. The string body 5 is joined to the side edge portions 4a and 4b of the bag body 1 by heat fusion. The string body 5 that constitutes the drink material filling pack together with the bag body 1 is made of the same material as the bag body 1, that is, a non-woven fabric.

The drinkable material filling pack of the present invention containing tea leaves and the like is used as follows. First, the user separates either the right end or the left end of the cord body 5 from the bag body 1. This process only needs to pull the cord body 5 a little harder, so that the heat-sealed portion of the cord body 5 becomes the bag body 1.
It comes off. Therefore, there is no need for tools such as scissors or knives.

After this treatment is completed, as shown in FIG. 4, the end portion which has just been cut off is picked up with a finger, and the drinkable material filling pack is dipped in a container filled with hot water. later,
In the same manner as in the conventional case, the string body 5 is manipulated to rock the bag body 1 vertically and horizontally to extract the components until a desired thickness is obtained. In addition to such usage, the filling pack for drinking material may be used in combination with a teapot. In this case, the cord 5 may be fixed by sandwiching the end portion of the cord body 5 between the teapot body and the lid, and may be soaked for a certain period of time as it is.

In the pack for filling a drinkable material of the present invention, since the bag body 1 can be handled by using the cord body 5 as described above, the bag body 1 can be moved up and down without using tools such as chopsticks and spoons even when immersed in hot water. You can rock it to the left or right. Further, the bag body 1 can be taken out from the container by picking the cord body 5 in the same manner. Therefore, it is not necessary to prepare tools such as chopsticks and spoons or to put them away, and it is possible to use them easily without any trouble.

Further, the pack for filling the drinking material of the present invention comprises
Since it is much easier to manufacture than conventional ones, it can be provided at a low cost. This is because mass production can be performed by using the manufacturing technology described later. The method of attaching the string 5 is not limited to the above-mentioned form, and can be changed as appropriate. For example, when it is desired to lengthen the cord body 5, the cord body 5 may be obliquely attached between the left and right side edge portions 4a and 4b. In particular, if the cord body 5 is attached along the diagonal line of the bag body 1, the maximum length can be obtained.

Further, in this embodiment, the cord body 5 is attached to the bag body 1 not at the center but at the opening side. This is for the purpose of indicating which side the opening is on. If the cord body 5 is attached to the bag body 1 in this way, the opening position can be immediately found, so that the trouble of searching for it can be saved and filling of the drinking material can be carried out more quickly. Next, the manufacturing technique of the pack for filling the drinking material will be described.
