DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a drip bag and a beverage drip bag in which a drip bag is filled with an extraction material such as coffee will be described in detail with reference to the drawings. In each figure, the same numerals indicate the same or equivalent components.
[0015]
Fig.1 (a) is a top view of one Example of coffee drip bag 100A which is one form of the drink drip bag of this invention, FIG.1 (b), (c) is explanatory drawing of the use condition, respectively. It is.
[0016]
A drip bag 1A used for the coffee drip bag 100A is composed of a bag body 2 made of a water-permeable filterable sheet material and a hooking member 3 provided on two outer surfaces of the bag body 2 facing each other. Yes.
[0017]
The bag body 2 has two rectangular surfaces 2a and 2b facing each other. For example, such a bag body 2 is formed by folding one rectangular sheet in half, using the folded mountain as the lower side of the rectangular surfaces 2a and 2b, and bonding or fusing both sides 2p and 2q of the rectangular surfaces 2a and 2b. (In FIG. 1A, the hatched portion of the horizontal line) can be formed by leaving the upper end as an opening. After the bag body 2 is filled with coffee powder, the opening is sealed. In addition, it is preferable to give the perforation 8 to the upper end part of the bag main body 2 for opening beforehand.
[0018]
As the water-permeable filterable sheet material forming the bag body 2, various materials can be used that are capable of brewing coffee when filled with a predetermined amount of coffee powder and poured. In general, as the sheet material for leaching, for example, synthetic fibers such as polyester, nylon, polyethylene, polypropylene, and vinylon, semi-synthetic fibers such as rayon, and woven or non-woven fabrics composed of natural fibers such as kouzo and mitsumata alone or in combination are used. Papers such as base paper for tea bags such as mixed paper made of Manila hemp, wood pulp, polypropylene fiber, etc. are known, and these can also be used in the present invention, but disposal properties after use of coffee drip bags From this point, it is preferable that the water-permeable filterable sheet material contains biodegradable fibers. Examples of the biodegradable fiber include polylactic acid, polybutylene succinate, and polyethylene succinate.
[0019]
On the other hand, the latch member 3 is provided on the outer surfaces of the rectangular surfaces 2a and 2b on the front and back of the bag body 2 so that the bag body 2 can be hung on the cup 30. In the latch member 3 of FIG. 1, a portion painted with fine dots is a portion attached to the outer surface of the bag body 2, and a portion painted with coarse dots is a portion not attached.
[0020]
The retaining member 3 is made of a thin plate material such as paper or a plastic sheet. This thin plate-like material is also preferably formed from a biodegradable material such as polylactic acid, polybutylene succinate, polyethylene succinate and the like from the viewpoint of disposal after use of the coffee drip bag 100A.
[0021]
The latch member 3 includes an adhesive portion 10 that is adhered to the outer surface of the bag body 2 by adhesion or fusion, a first latch portion 5, and a second latch portion 7. The sticking portion 10, the first hooking portion 5, and the second hooking portion 7 are formed by punching one sheet-like material.
[0022]
The 1st latching | locking part 5 is formed so that it can be raised from the outer surface of the bag main body 2, and is following the sticking part 10 and the broken line L1. The broken line L1 is formed at the substantially central portion of the latch member 3. Further, the first hooking portion 5 is formed with a hooking concave portion 4 for the upper edge portion of the cup when the drip bag 1 </ b> A is hung on the cup 30.
[0023]
The second hooking portion 7 is formed continuously with the sticking portion 10 on the side opposite to the first hooking portion 5 with the polygonal line L1 interposed therebetween. The second hook 7 is also formed with a hook recess 6 for the upper edge of the cup when the drip bag 1 </ b> A is hung on the cup 30. Accordingly, in this drip bag 1A, the latching recess 6 and the above-described fold line L1 are unevenly distributed in one half of the horizontal direction of the latching member 3, and as described later, the opening diameter is small. It is possible to stably hold the drip bag 1A on various cups from a cup to a large cup.
[0024]
The size of the latching recess 6 of the second latching portion 7 is such that the recess depth H2 is shallower and the width W2 is wider than the latching recess 4 of the first latching portion 5. Is preferable from the standpoint that the drip bag 1A can be stably hooked to cups having various opening diameters. For example, the bag body 2 is recessed when the height H1 of the bag body 2 is 70 to 100 mm and the width W1 is 65 to 85 mm. The depth H2 is 3 to 10 mm and the width W2 is 5 to 20 mm.
[0025]
In addition, although the 2nd latching | locking part 7 is not stuck on the outer surface of the bag main body 2, since it does not use and raises like the 1st latching | locking part 5, it sticks with the 2nd latching | locking part 7 and it. A broken line is not formed in the portion where the landing portion 10 continues.
[0026]
Although there is no particular limitation on the overall size of the latching member 3 including the sticking part 10, the first latching part 5, and the second latching part 7, the coffee drip bag 100A is hung on the cup 30. In this case (see FIG. 1 (c)), if the size is too small, the stability of the shape of the bag body 2 is lowered. For example, the height H1 of the bag body 2 is 70 to 100 mm and the width W1 is 65 to 85 mm. Further, it is preferable that the height H3 of the hooking member 3 is about 35 to 85 mm and the width W3 is about 35 to 75 mm.
[0027]
As a method of extracting coffee using the coffee drip bag 100A, first, the bag body 2 is opened by cutting the upper end portion of the bag body 2 along the perforation 8, and the arrow in FIG. As shown by (1), the 1st latching | locking part 5 is raised from the outer surface of the bag main body 2. As shown in FIG. Next, as shown in FIG. 1C, the first latching portion 5 and the second latching portion 7 are latched so as to be hooked on the wall 31 of the opening of the cup 30. Thus, the coffee drip bag 100A is set in the cup 30 and then poured from the opening 9 of the bag body 2.
[0028]
By setting the coffee drip bag 100A in the cup 30 in this way, as shown in FIG. 2, the bag body 2 is attached to the cup 30 at a total of four locations including the first hook portion 5 and the second hook portion 7. It is hooked. When the bag body 2 is hooked on the cup 30 at only two locations of the first hook portion 5, the bag body 2 is inclined and the opening 9 is likely to be narrowed when pouring, but as in the coffee drip bag 100A, By hooking the bag main body 2 on the cup 30 at four locations, the opening 9 of the bag main body 2 can be maintained in a wide open state during pouring.
[0029]
Moreover, according to this coffee drip bag 100A, since the recessed part 6 for latching and the above-mentioned broken line L1 are unevenly distributed in the area | region of the one side half of the horizontal direction of the latching member 3, as shown in FIG. Even when the opening diameter of the cup 30 is large, the coffee drip bag 100A can be set in the cup 30 and the opening of the bag body 2 can be maintained in a wide open state.
[0030]
In the above description, an example in which the coffee drip bag 100A is set in the cup 30 after the coffee drip bag 100A is opened at the perforation 8 is shown, but the method of using the coffee drip bag 100A of the present invention is not limited thereto. Alternatively, the coffee drip bag 100A may be opened after the coffee drip bag 100A is set in the cup 30.
[0031]
FIG. 4 is a perspective view of an unopened state of the coffee drip bag 100B according to a different embodiment of the present invention. This coffee drip bag 100B is obtained by folding the sheet material at the bottom of the bag body 2 and attaching the gusset 11. Thereby, the open shape of the opening 9 of the bag body 2 is further stabilized.
[0032]
In addition, the present invention can take various forms. For example, the perforation 8 at the upper end portion of the bag body 2 of the coffee drip bags 100A and 100B described above is provided to facilitate opening of this portion, but this portion can be easily replaced with the perforation 8. It may be sealed by thermal bonding to such an extent that it can be peeled off.
[0033]
Moreover, as an extraction raw material with which the drip bag of the present invention is filled, tea leaves such as black tea and green tea, Chinese herbal medicine, etc. may be used instead of coffee powder, and various beverage drip bags can be obtained thereby.
[0034]
