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 present inventor has submitted a simple, disposable filter suitable for filtering coffee, etc. through applications such as Utility Application No. 56-31751, but the present inventor has further improved the filter related to this already proposed filter. The purpose is to make the filter easier to handle and increase its practical value.

The filter suitable for filtering coffee, etc. proposed earlier has an opening for pouring hot water in the center of a substrate made of thick paper, etc., and a structure that surrounds the opening on the bottom surface of this substrate. The opening edges of a filter paper bag formed in a bag shape are fixed together to form the main body of the filter, while support leg pieces for supporting the substrate are extended symmetrically from both sides of the substrate, and A substantially U-shaped notch is provided near each edge of both support leg pieces, and by forming this notch, a tongue-shaped inner clamping piece and an opposing outer clamping piece are integrally provided. It was something I made.

When using the filter according to the existing proposal, the supporting leg pieces extending from both sides of the base plate are bent downward, and the tongue-shaped inner clamping pieces provided at each tip are used to hold the coffee cup. into the inside of the rim of the container, and at the same time attach the other outside clamping piece to the outside of the rim, and clamp the rim of the container with these two pieces,
With this, both support leg pieces are fixed to the edge of the container, and the filter is placed and fixed on top of the container in an upright manner.Next, to filter coffee, etc., after standing up in this way, It was used by placing coffee powder in a filter paper bag and pouring hot water through the opening of the base plate so that the coffee liquid was directly received in the container.

As mentioned above, this filter fits well in the container, and the inner and outer clamping pieces provided on both supporting leg pieces securely hold the edge of the container, so it has an excellent function that allows it to be set in a stable state. One difficulty in use was that it required some skill to operate the inner and outer gripping pieces to engage the rim of the container.

That is, as mentioned above, before this gripping piece is attached to the edge of the container, the left and right support leg pieces are bent downward into a substantially U-shape around the flattened base plate, which generates a repulsive force. It is difficult to match the gap between the leg ends of both support leg pieces, that is, the edges where the inner and outer clamping pieces are provided, to the size of the rim of the container (diameter of the mouth), and the inner and outer clamping pieces of each support leg piece are difficult to match. The pieces are formed by forming notches, and in normal conditions, both the holding pieces are flush with each other, and there is no spontaneous gap between the two pieces to hold the edge of the container, so this filter is When setting the filter in a container, it is necessary to bend the filter body and hold both support legs bent downward, and to open the inner and outer clamping pieces of both support legs inward and outward to secure the edge of the container. It required work to make it easier to accept, and it required some skill to do this work at the same time.

The present invention was devised in view of such troublesome handling, and consists in an improvement so that it can be easily, reliably and quickly set into a container.

Hereinafter, embodiments illustrating the present invention will be described.

Figure 1 is a plan view of the filter according to the present invention;
The figure is a bottom view. The filter shown here is substrate 1
is made of a rigid material such as cardboard, and a pair of support legs 2, 2 are extended symmetrically on both sides of the support leg, so that the overall shape is a horizontally long plate. An opening 3 for pouring hot water is provided in the center of the substrate 1, and a filter paper bag 4 is attached to the lower surface so as to surround this opening.

The filter paper bag 4 is made of filter paper,
In this embodiment, as shown in FIG. 7, a filter paper cut into a substantially rectangular shape is folded in half at the center, and the edges 5, which are aligned on both sides, are glued to the middle of the length to form a flat bag portion 6. On the other hand, the free pieces bordering on the opening 7 of this bag part are used as mounting pieces 8, and the peripheral edges 9, 9 of both mounting pieces are attached to the lower surfaces of the substrate 1 and the support leg pieces 2, 2. It is ready to be worn and installed.

This filter paper bag 4 has an opening 7 before using the filter.
are closed together in a straight line, and the bag section 6 is folded with the closed openings folded as shown in FIGS. When used, the opening 7 is opened by bending both supporting leg pieces 2, 2 downward, and the opening 7 is exposed to the opening 3 of the board. Coffee powder etc. can be put into the bag part 6 through the opening part 3.

Reference numeral 10 in the figure indicates the edge 1 of each support leg piece 2, 2.
A substantially U-shaped notch is formed near 1 and 11, 12 is a tongue-shaped inner clamping piece formed on the support leg piece by this notch, and 13 is opposed to this inner clamping piece. This is an outer clamping piece provided as a
Reference numeral 14 denotes a knob integrally extending from the center of the edge of the outer holding piece 13 so as to protrude outward.

The inner and outer clamping pieces 12 and 13 are for fixing the support leg pieces 2 and 2 to the edge of the container when the filter is set on a container 15 such as a coffee cup, and the gripping piece 14 It is used to hold the filter body during operation, and to open the outer clamping piece 13 outward to create a gap between it and the inner clamping piece 12 to receive the edge of the container.

Next, to further explain the features of the present invention related to the above configuration through the work of setting the filter, FIG. As shown in the figure, when setting up the filter, first grasp the tabs 14, 14 protruding from the outer clamping pieces 13, 13 of both support leg pieces 2, 2 with both hands, and then remove the left and right support legs together with the base plate 1. The piece is bent into an inverted U-shape, and the distance between the inner clamping pieces 12, 12 provided at the ends thereof is adjusted to the inside of the opening of the container. FIG. 8 shows exactly this state. Next, in this state, the container is lowered and both inner clamping pieces 12, 12 are pushed inside the rim of the container, and then the gripping pieces 14, 14 are are released and the outer clamping pieces 13 are attached to the outside of the container to clamp the edges of the container from the inside and outside, completing the setting work. Figures 9 and 10 show the state when this set is completed,
The filter will be stably fixed on top of the container.

As described above, the filter of the present invention has the gripping piece 14 on the outer clamping piece 13, so that the filter can be deformed into a predetermined bent state by gripping the gripping piece 14.
By lowering it onto the container in this state, both support leg pieces can be fixed to the edge of the container at the same time, allowing for quick setting work. Particularly, by pinching the knob 14, the outer clamping piece 13 of the inner and outer clamping pieces 12 and 13, which are flush with each other in the normal state, is opened outward, and the inner clamping piece 12 protrudes straight. Since the work of inserting it inside the edge of the container and the work of putting it on the outside are performed at the same time, it can be easily set without requiring any special procedures.

Of course, in the above method, the case where both supporting leg pieces are fixed to the container at the same time has been explained, but it goes without saying that the supporting leg pieces can be set in a stable state even if they are latched and fixed one at a time.

By the way, in the above embodiment, the knob piece 14 is divided into two parts at the center and is composed of two pieces.
This means that when the outer clamping piece is hooked onto the rim of a container such as a coffee cup, it will move 2 times along the arcuate surface of this rim.
This is done in order to ensure reliable contact at the points and stabilize the engaged state, and it may be made to protrude as a single piece from the edge of the outer clamping piece 13 as shown in FIG. 11. In short, the gripping piece 14 in the present invention may be any protruding piece that extends from the outer clamping piece and is large enough to be picked up with fingers, and its shape is not specified.
