DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter used for a strainer for beverages such as coffee and an improvement of a strainer for beverages having the filter.

[0002]

2. Description of the Related Art This type of strainer for beverages such as coffee is disclosed in Japanese Utility Model Laid-Open No. 55-130628 and Japanese Utility Model Application 2-23.
No. 206, No. 5-3171, No. 8-1709
And JP-A-8-10168 have been proposed. These beverage strainers include a bag-shaped filter and a support member, and the upper end of the filter is bonded to the support member via glue, and the support member is used for a container such as a cup. When placed on the top, beverages such as coffee can be filtered with a filter. (Figure 1
2, see FIG. 13). However, since the filter is bonded to the support member via the glue, the glue must be interposed between the filter and the support member each time.
As a result, there is a problem that the bonding operation is troublesome and time is required.

[0003] The above-mentioned conventional strainer for beverages has the following problems. For example, Japanese Utility Model Publication No. 55-130628,
Japanese Utility Model Publication No. 2-23206 and Japanese Utility Model Publication No. 5-3171 have a cylindrical support member having three or four side walls connected to each other, and a supporting portion for a coffee cup at a lower end thereof. Is provided. Therefore, in the case of a coffee cup having a diameter larger than the size of the cylindrical body formed by the side wall, there is a problem that a strainer cannot be placed on the coffee cup. In each case, the state in which the filter is housed in the side wall can be viewed only from above, and the state of coffee extraction cannot be confirmed by viewing the coffee extraction state from the side of the filter.

In Japanese Utility Model Publication No. Hei 8-1709, as shown in FIG. 13, one end of two side walls 101 and 102 is connected to each other, and the other end is connected by an expansion holding piece 103. is there. This has an advantage that the filter 104 can be viewed from above from above the expanding holding piece 103, although there is a limit in adaptability to the size of the cup. However, the direction in which the filter 104 is viewed is limited to one location in front, and the filter is often arranged in a state where the filter margin 105 comes to this one location. In some cases, it was difficult to see.

Japanese Unexamined Patent Application Publication No. Hei 8-10168 discloses a structure in which left and right side walls 201 and 202 and a front side wall 203 are arranged as shown in FIG.
And the mounting portion is formed on the left and right side walls 201 and 20.
2 are formed integrally from the lower part of the front wall 203 toward the lower part of the front wall 203, and the mounting portions 204 and 205 project forward from the front wall 203 in an assembled state. Thus, the mounting portions 204 and 205 can be formed so as to protrude from the cylindrical body, and are easily adapted to the size of the cup. However, as shown in FIG.
Reference numerals 04 and 205 project obliquely forward, and the interval between the mounting portions cannot be made as large as expected. In addition, since two mounting portions 204 and 205 are formed from a portion of one side wall (that is, the front side wall 203), the length of each mounting portion is equal to or more than half the length of the front side wall 203. There are also limitations that you can't do. Also, in this case, the filter can be seen from below the front side wall 203, but there is a problem that the filter can be seen only from one place as in the case of the previous one.

The end of the filter 8 is attached to a support member 10, and the support member 10 is placed on a container such as a cup, so that the filter 8 is attached to the support member 10 in the form of a bag. The present invention provides a filter 8 of a beverage strainer which is supported in a state in which the beverage is filtered so as to be able to strain a beverage such as coffee. The filter of the first invention of the present application comprises at least an outer layer 81 forming the outer peripheral surface of the bag-shaped filter 8 and an inner layer 82 arranged inside the outer layer 81 and forming the inner peripheral surface of the bag-shaped filter 8. It has two layers. The inner layer 82 is composed of a heat-fusible material that can be fused by heating, and the outer layer 81 is composed of a material that cannot be fused at a temperature at which the inner layer 82 can be fused. At the end of the filter 8, mounting portions 84 for mounting to the support member 10 are provided. The attachment portions 84, 84 are formed by folding a part of the end of the filter 8 or the entire end toward the inner layer 82 side.

In the filter 8 of the first invention of the present application, the inner layer 82 made of a heat-fusible material that can be fused by heating, and the material that cannot be fused at a temperature at which the inner layer 82 can be fused. It is assumed that at least two layers including an outer layer 81 are provided, and attachment portions 84, 84 of the filter 8 to the support member 10 are formed by folding an end of the filter 8 toward the inner layer 82. By doing so, for example, as shown in FIG. 9, when attached to the collapsible tubular body 10 as a support member in the beverage strainer, the adhesive layer 12a which can be adhered by heating,
Attachment portions 84, 84 of the filter 8 are arranged between the left and right side walls 1, 1 of the tubular body 10 provided with 12a, and in that state, the temperature is set to a temperature at which the adhesive layers 12a, 12a can be in an adhesive state. The heated molds K, K may be pressed from the outside of the left and right side walls 1, 1 in the cylindrical body 10 in a direction approaching each other.
By the adhesion of 2a, 12a, both the left and right mounting portions 84, 84 of the filter 8 can be adhered to the opposing surfaces of the left and right side walls 1, 1, respectively. Further, the left and right mounting portions 84 of the filter 8 come into contact with each other due to the embossing.
Since the outer layers 81 and 81 are opposed to each other and the outer layers 81 and 81 are in contact with each other, it is possible to prevent the attachment portions 84 and 84 from adhering to each other. Therefore, the attachment between the filter 8 and the tubular body 10 can be easily performed in a short time, merely by embossing, without using glue as in the related art. Can be something.
In forming the attachment portions 84 of the filter 8, a part of the end of the filter 8 or the entire end is folded back to the inner layer 82 side. Can be covered from outside both sides. As a result, when the end of the folded filter 8 is embossed with a mold heated to a temperature at which the inner layer 82 can be fused, the outer layer 81 is pressed.
Thereby, the inner layers 82 can be adhered to each other while preventing the inner layers 82 in the fused state from attaching to the mold,
The mounting portions 84 can be easily formed. Furthermore, when the filter 8 is formed in a bag shape with both front and rear ends closed as shown in FIG. 1, for example, after the front and rear both ends are overlapped,
If the overlapped portion is stamped with a mold heated to a temperature at which the inner layer 82 can be fused, the outer layer 81 prevents the fused inner layer 82 from adhering to the mold. Adhesive portions 85, 85 can be formed by easily closing both front and rear ends, and a bag-like filter having both front and rear ends closed can be easily formed.

The filter according to the second invention of the present application comprises an outer layer 81 forming the outer peripheral surface of the bag-shaped filter 8,
And at least two layers with an inner layer 82 which is arranged inside the filter and forms the inner peripheral surface of the bag-shaped filter 8. Inner layer 82
Is composed of a heat-fusible material that can be fused by heating, and the outer layer 81 is composed of a material that cannot be fused at a temperature at which the inner layer 82 can be fused. At the end of the filter 8, two mounting portions 84a and 84b for mounting to the support member 10 are provided. The one-side mounting portion 84a is formed by folding the end of the filter 8 toward the inner layer 82, so that the outer layer 81 of the one-side mounting portion 84a and the inner layer 8 of the other-side mounting portion 84b are formed.
