Description

[Detailed description of the invention] This invention is a coffee cup or other container that is placed and fixed in an upright shape on the edge, and by pouring hot water into the coffee powder, etc. stored in a filter paper bag, coffee liquid, etc. is directly poured into the container. This invention relates to an improvement in a filter that can extract filtrate.

The inventor of this invention has already proposed a filter in 1975-31751, which is a simple filter suitable for filtering coffee, etc., which is made of thick paper or the like and is equipped with a filter paper bag.
The present invention improves the handling of this filter and improves its practicality.

In other words, the coffee filter proposed earlier has an opening for pouring hot water into the center of a substrate made of thick paper, etc., and a bag-like shape is placed on the bottom surface of the substrate to surround this opening. While the opening edges of the formed filter paper bag are fixed together to form the main body, supporting leg pieces for supporting the substrate are extended symmetrically on both sides of this substrate, and furthermore, the ends of both supporting leg pieces are extended symmetrically. A substantially U-shaped notch was provided near the edge, and by forming this notch, a tongue-shaped inner clamping piece and an opposing outer clamping piece were integrally provided.

The filter according to this existing proposal has support leg pieces extending from both sides around the base plate bent downward, and a tongue-shaped inner clamping piece provided at each tip of the support leg pieces placed inside the rim of a container such as a coffee cup. The other outer clamping piece is placed on the outside of the rim, and these two pieces sandwich the rim of the container from the inside and outside, so that it can be placed and fixed on top of the container in an upright position, and then When filtering coffee, etc., coffee powder is placed in the filter paper bag, hot water is poured through the opening of the substrate, and the filtrate, that is, the coffee liquid, is directly received in the container.

This filter is used by placing it directly on the container as described above, but in actual handling, as described above, the operation of bending both support leg pieces and the inner and outer clamping pieces of both support leg pieces are required. is set on the container through an operation of hooking it to the edge of the container. In this case, the usual method is to grasp the filter from above with one hand, bend it into an inverted U shape, turn both support leg pieces downward, and then hook the inner and outer clamping pieces to the edge of the container to set the filter. Due to the slippery surface, it was sometimes difficult to grasp it properly, and I ended up having to use both hands.

In view of this operability, the present invention further improves the previously proposed filter by making it possible to easily bend both support leg pieces and engage the inner and outer clamping pieces with the edge of the container with one hand. The purpose is to make handling even easier.

Next, to explain the features of this invention with reference to an embodiment illustrating the invention, the substrate 1 of the filter is formed of a material having the required rigidity, such as cardboard or a sheet made of synthetic resin, and hot water is poured into the center of the substrate 1. An opening 2 for pouring is provided. Support leg pieces 3, 3' are provided on both left and right sides of the board to support the board in a symmetrical manner.
are integrally extended to form a horizontally elongated rectangular shape as shown in the figure, and a filter paper bag 4 is integrally attached to the lower surface of the substrate.

The filter paper bag 4 is formed into a bag shape using filter paper as a material. In this embodiment, as shown in FIG. The part 5 is glued to the middle of its length, thereby forming a bag part 6 which is folded into a flat shape, while the part that becomes a free piece with the opening 7 of this bag part as a border is attached to a mounting piece 8, As 8, the edges 9 of both mounting pieces,
9 is attached to the lower surface of the substrate 1 by attaching it to the lower surface of the substrate 1 and the support leg pieces 3, 3 which are extended left and right around this.

The filter paper bag 4 attached in this manner can be folded into a flat shape by closing the opening 7 in a straight line when the filter is not in use, and folding the opening into a fold as shown in FIGS. 2 to 6. The bag portion 6 is placed on the bottom surface of the substrate, and the entire structure including the substrate 1 and supporting leg pieces 3 and 3' can be folded into a flat shape. Furthermore, in this case, it is also possible to fold the base plate and both supporting leg pieces in two based on the central portions, with the bag portion 4 sandwiched between them. When in use, both supporting leg pieces 3, 3' are
In conjunction with the bending operation, the linearly closed opening 7 is opened to face the opening 2 of the substrate 1, and coffee powder, etc. is introduced into the bag 6 through the opening 2. Become.

In the figure, 10 is the edge 1 of the supporting leg pieces 3, 3'.
There is a U-shaped notch near 1 and 11,
Reference numeral 12 denotes a tongue-shaped inner clamping piece formed on the support leg piece by this notch, and numeral 13 denotes an outer clamping piece provided opposite to this inner clamping piece. Reference numeral 14 denotes a finger hook portion formed by a circular notch in the center of the inner clamping piece 12 formed above.

The inner and outer clamping pieces 12 and 13 are for fixing the support leg pieces 3 and 3' to the edge of the container when the filter according to the above structure is set on the container 15 such as a coffee cup, and are used as finger hooks. The portion 14 is for hanging the thumb or any of the other three fingers so that the holding pieces 12, 13 can be hung on the edge of the container with one hand during this setting.

Next, to further explain the present invention through the setting of this filter, FIG. 8 shows a state in which the flat filter shown in FIGS. 1 to 6 is set on the upper part of the container 15. It is.

As shown here, to set up the filter according to the present invention, first, the flat substrate 1 is bent downward, and the left and right supporting leg pieces 3, 3' are turned into an inverted U.
In this state, place your hand on top of the filter, hook the abdomen of your thumb on the finger hook 14 provided on the inner clamping piece 12 of one support leg piece 3, and then press the finger hook on the other support leg piece 3'. Hold the part 14 with either your index finger, middle finger, or ring finger and grasp it from above,
In this state, the edges of both support leg pieces face the edge of the container 15. When you grip the filter with your thumb and any of the other three fingers in this way, the inner gripping piece 12 will be pressed by your fingers.
bends inward and a gap is naturally created between it and the outer clamping piece 13, so when the edge of the container is inserted into this gap, the inner clamping piece 12 is inserted inside the edge, and the outer clamping piece 12 Piece 13 will protrude outside the edge. When you release your hand in this state, the pressed inner clamping piece 12 returns to the restored outer clamping piece 13.
At the same time, the left and right support leg pieces 3, 3' try to restore the flat state, so the inner clamping piece 12 presses the inner wall of the container even more firmly and bites into it, resulting in filtration. The device will be fixed on the container in a stable state.

FIGS. 9 and 10 show a state in which the filter has been completely set, and the filter is fixed in an upright position on the container by being clamped by the inner and outer clamping pieces of the supporting leg pieces.

As explained above, the filter of the present invention can be easily set on the container with one-handed operation, and this work is much easier and can be done reliably and quickly compared to the conventional filter. There are advantages.

In the above embodiments, the finger hook provided on the inner clamping piece was made into a circular through hole, but it could also be formed into a depression by drawing, or in some cases, the surface of the inner clamping piece could be formed into a corrugated uneven surface. You may.

In short, the shape of this finger grip is well specified as long as it can be used to hold the thumb and any of the other three fingers so that they do not slip when gripping the filter from above, and can be held with one hand. It's not a thing.
