Description

[Detailed description of the invention] This invention is a coffee cup that is placed and fixed on a suitable container such as a coffee cup, and the coffee liquid is extracted directly into the container by pouring hot water into the coffee powder stored in the filter paper bag. This invention relates to a coffee filter that can be folded flat when not in use, making it convenient to carry and handle, and also allows the coffee to be placed in a stable state and easily on a container when in use. Our purpose is to provide filters.

Examples illustrating the present invention will be described below: 1.
2 is a pair of support leg pieces made of a sheet having the required rigidity, such as a sheet of cardboard or a synthetic resin sheet;
It is a filter paper bag for storing.

The pair of supporting leg pieces 1 and 2 have the same rectangular shape, and their upper edges 1' and 2' are integrally connected via a connecting piece 5. The combination is such that it can be bent freely and roughly cut into a ``■'' shape.

Each of the supporting leg pieces 1 and 2 has a U-shaped notch 6, 6 at the same position near the leg end, and the formation of the notch allows the tongue-shaped inner clamping piece 7 to form a band-like shape. An outer clamping piece 8 is provided.

A rectangular pouring spout 9 is provided in the upper center of one of the support leg pieces 1, and the filter paper bag 3 is attached to the back side of the spout 9.

The filter paper bag 3 has its opening edge aligned with the opening of the pouring spout 9, and is attached so as to surround it so that the bottom of the bag hangs down, and the entire bag is attached between the supporting leg pieces 1.2. It is designed to fit in.

In this embodiment, the side surface of the bag and the back surface of one of the support legs 2 facing the bag are partially glued 10 so that the bag is suspended from both support legs.

In addition, 11 and 12 in the figure are bending lines provided halfway between the heights of both support leg pieces.

The filter of the present invention is constructed as described above, and when it is not in use, such as when being carried around, both support leg pieces 1 and 2 are folded up and the filter paper bag 3 is placed between them, and the filter paper bag 3 is kept in a flat state and handled, and when in use, the support legs It is used by opening the leg of the piece and placing and fixing the leg end on the opening lift of a container such as a coffee cup.

FIGS. 3 and 4 show how this filter is used. First, when the support leg pieces 1 and 2 are folded flat, the filter paper bag 3 sandwiched between them is pulled by the adhesive point 10. It will automatically inflate the inside.

In this state, the container 13 is faced from above, and first the outer clamping pieces 8 provided at the end of each leg of both supporting leg pieces are brought into contact with the outside of the edge of the container, and then the tongue-shaped inner clamping pieces 7 are placed on the edge of the container. It is inserted into the inside, and the inner and outer clamping pieces clamp the edge of the container and fix it to the container.

After that, the required amount of coffee powder 4 is poured into the pouring spout 9, hot water is poured into it, filtered, and the coffee liquid is directly received in the container.

Incidentally, the opening of the supporting leg pieces is arbitrarily determined depending on the size of the container, but the inner and outer clamping pieces 7 and 8 provided at the leg ends should be bent so that they face as straight as possible along the rising direction of the edge. By bending both support leg pieces 1 and 2 into a bent shape using lines 11 and 12, the fixation to the container becomes stable.

As mentioned above, the filter of the present invention can be folded flat when not in use, making it easy to handle when carrying or storing. The container can be easily set by opening the legs and then clamping the edges of the container using the inner and outer clamping pieces provided at the ends of each leg, so that the container can stand on its own on top of the container.

Moreover, in this case, the above-mentioned clamping piece is a piece formed by cutting out the supporting leg piece with the required rigidity, and since it has the property of always being aligned on the same plane, it is expected that it will have a strong clamping effect when it grips the edge of the container. This allows it to be firmly fixed, and
Since the support leg pieces can freely change the leg width, they can be set in various containers without being affected by the size of the container.

Furthermore, since the supporting leg pieces that form the pair are set in a chevron-shaped state, they can stand on their own on the container in a stable state, so when pouring coffee powder into a filter paper bag or pouring hot water, It has the advantage of being safe to use without the risk of falling over.

[Brief explanation of the drawing]

The drawings show one embodiment of the filter according to the present invention, and FIG. 1 is a front view, FIG. The figure is a sectional view taken along the line IV-IV in the upper figure. 1.2 is a support leg piece, 3 is a filter paper bag, 6 is a notch, 7 is an inner clamping piece, 8 is an outer clamping piece, and 9 is a spout.

Claims (1)

[Scope of utility model registration request] A pair of supporting leg pieces whose upper edges are bent freely and connected to each other in a cross-sectional ■-shape are provided with a substantially U-shaped cutout at the end of each leg, and each has a tongue-shaped inner clamping piece. A band-shaped outer holding piece is provided, while a spout is provided on one side of the support leg piece, and the opening edge of a filter paper bag is attached to the back side of the spout so as to surround the spout, so that it is suspended.
