Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an improvement of a disposable coffee dripper.

[Prior Art] Various types of disposable coffee drippers have been proposed and used as a disposable coffee dripper that can be easily used for coffee, but each has advantages and disadvantages in terms of usability and safety. However, the reality is that there are few that are completely satisfactory.

For example, in the one shown in FIG. 3, a flat-shaped folded paper container 30 is spread in a triangular shape and placed on a cup 31,
After filling coffee in the deep plate-shaped filter 32 installed inside it, boiling water is poured, but since the container 30 has a triangular shape, its volume is small relative to the outer shape, and boiling water is added in small steps. In addition to the inconvenience of having to pour in the coffee, there is the inconvenience of having to fill the filter 32 with coffee one by one. Moreover, when pouring the above boiling water, it is often done in a circle so that it spreads evenly throughout the coffee,
In the above-mentioned conventional coffee dripper, since the container 30 has a triangular shape and a small volume, it is extremely difficult to pour boiling water in a circle, and there is a high risk that it will easily spill into the surroundings. Also, when pouring boiling water, when the expanded container 30 tries to return to its original flat state due to the folding tendency, the area of the opening of the container 30 becomes smaller, so pour boiling water in a circle. Can't do it.

In the coffee dripper shown in FIG. 4, a bag-shaped filter 42 containing coffee in advance is attached to the opening 41 of the mount 40 having the opening 41, and both ends of the mount 40 are attached to the edges of the cup. It has locking parts 43, 43 for locking, and when using it, as shown in FIG.
After opening the filter 42 at the opening 41, mount 40
Is curved in a chevron shape, and the inner locking piece 44 and the outer locking piece 45 in the locking portion 43 hold the mouth of the cup 46, and the outer locking piece 45 is formed into a flange shape on the outer circumference of the mouth. By engaging with the edge 47, it is placed on the cup 46, and in that state, hot water is poured into the filter 42 through the opening 41.

However, since this coffee dripper has the brim-shaped edge 47 as described above provided at the mouth of the cup 46, it can be stably placed on the cup by locking the outer locking piece 45 thereto. However, since it is necessary to bend the chevron in order to place it on the mouth of the cup 46, the effective opening area of the opening 41 becomes small. Therefore, similar to that shown in FIG. Difficult to pour.

[Problems to be Solved by the Invention] The problem to be solved by the present invention is that it can reliably and stably mount on any cup, and can reliably hold a cylindrical shape, and therefore has a large volume. Another object of the present invention is to provide a coffee dripper capable of pouring hot water in a circle in a safe manner.

[Means for Solving the Problems] In order to solve the above problems, a coffee dripper according to the present invention is provided with at least three side surfaces of a cylindrical container which is folded flat and expanded into a cylindrical shape during use. A leg piece for mounting on the cup is formed by cutting and raising the container, and at least the upper end of the container, a shape-retaining piece for holding the container in a cylindrical shape by folding the container inward when the container is expanded, It is characterized in that it is formed so as to straddle both sides of the fold line, and that a filter that also serves as a package enclosing coffee is attached inside the container so as to be opened by expanding the container.

In order to solve the same problem, the coffee dripper is characterized in that both ends of the mouth of the filter are cut obliquely.

[Operation] When the coffee dripper is used, the container is expanded into a cylindrical shape, and the expansion causes the filter to open,
Then, the shape-retaining piece provided on at least the upper end of the container is bent inward to maintain the cylindrical state, and further, the leg pieces on the side surface of the container are erected in the radial direction, and these leg pieces are attached to the rim of the cup. Set on the cup by placing.

Since the leg is provided at three places, the container has very good stability and does not move or fall unnecessarily.

After placing the container on the cup, pour boiling water into the inside of the filter, but since the container is cylindrical, it can be poured easily and safely in a circular motion, and its volume is large. Therefore, it is possible to pour a certain amount of hot water at a time, and it is not necessary to pour in small amounts.

Also, when pouring boiling water, if the container returns to its original flat state due to the folding tendency, the boiling water will pour the container directly into the cup, or it will be poured outside the cup.
Since the expanded state of the container is maintained by bending the shape-retaining piece, it is possible to prevent the hot water from deviating from the container and soiling the surroundings or causing burns.

Further, if both ends of the mouth of the filter are cut obliquely, the filter can be smoothly opened following the expansion of the container.

[Embodiment] An embodiment of the present invention will be described below in detail with reference to the drawings.

In FIG. 1, 10 is a container made of cylindrical paper or synthetic resin, and 11 is a filter attached to the inside of the container 10 which also serves as a package. Coffee is enclosed in the filter 11. Has been done.

The container 10 is folded into a flat state at the fold lines 12 and 12 in a shape crushed in a diametrical direction from the side surface before use,
When used, it expands into a cylindrical shape that expands upward (see Fig. 2)
And the fold line at the upper and lower ends of the container 10.
Shape-retaining pieces 13 and 14 are formed at positions corresponding to 12 and 12, respectively, so as to straddle both sides of the folding lines 12 and 12, and these shape-retaining pieces 13 and 14 are formed when the container 10 is expanded. The container 10 can be held in a cylindrical shape by folding the insides of the containers 14 and 14, respectively. The shape retaining piece may be provided only on the upper end of the container 10.

Further, on the side surface of the container 10, a leg piece 15 for placing on a cup is formed so as to be able to be erected by cutting and raising the container 10 in at least three places in a circumferential direction. The lower side of the leg piece 15 is provided with unevenness 16 to prevent slippage.

On the other hand, the filter 11 is a bag-shaped one filled with coffee, and the mouth 11a thereof is closed in a straight line, and is adhered and sealed so that it can be easily peeled off when necessary. It is attached to the container 10 by adhering the rim portion to the inner surface of the container 10, and when the container 10 is expanded, the mouth portion 11a is opened by pulling and peeling the rim portion in both directions. Where both ends 1 of the closed mouth 11a of the filter 11 are
By cutting 1b and 11b diagonally and increasing the opening range, it is possible to easily open the body following the container.

When the coffee dripper having the above structure is used, the container 10 is expanded into a cylindrical shape as shown in FIG. 2, and the filter 11 is opened to follow the expansion of the container 10 and the upper and lower shape-retaining pieces 13 and 14, respectively. The container 1 by folding it inside
0 is held in a cylindrical shape, and the leg pieces 15 on the side surface are further erected in the radial direction. Then, the leg pieces 15 are placed on the cup 17 by being locked to the rim of the cup 17. At this time,
Since the leg pieces 15 are provided in three places, the stability is very good. Moreover, since the unevenness 16 is formed on the lower side of each leg piece 15, it is difficult to slide on the cup 17 and it temporarily moves. Even so, since the lower end of the container 10 is fitted in the cup,
The container 10 does not come off the cup.

Thus, after placing the container 10 on the cup 17, the filter
Hot water is poured into the inside of 11, but the container 10 has a cylindrical shape, and since the cylindrical expanded state is maintained by folding the upper and lower shape-retaining pieces 13 and 14, the hot water follows the circle. It is possible to pour safely while making a circle, and since its volume is large, a certain amount of hot water can be poured at once. Further, at the time of pouring, through the gap between the side surface of the container 10 and the cup 17, or through the window hole 18 after cutting and raising the leg piece 15 of the container 10, the cup is
Since the amount of coffee in 17 can be confirmed, the pouring amount can be easily adjusted accordingly.

The dripper after use can be folded again into a flat shape so that coffee will not spill, and then discarded as appropriate.

[Advantage of Invention] As described above, according to the coffee dripper of the present invention, since it can be expanded into a cylindrical shape, when pouring hot water, it is possible to safely draw a circle along the circle. In addition, it can be poured easily, and since it has a larger volume than the conventional one having a triangular shape, it is possible to pour a certain amount of hot water at once, and it is not necessary to pour it in small portions.

In addition, since the leg pieces are formed by cutting and raising the container at least at three places on the side surface, and the leg pieces are used to mount the leg pieces, it is very easy and stable for any cup. Can be placed on the screen.

Furthermore, at least the upper end of the fold line of the container is provided with shape-retaining pieces that straddle both sides of the fold line, and the expanded state of the cylindrical container is maintained by folding these shape-retaining pieces inward, When pouring, the container can be prevented from returning to its original flat state due to the folding habit.
