Description

[Detailed description of the invention] The present invention relates to a filter for coffee, etc., which is placed on top of a container such as a coffee cup and is capable of extracting coffee liquid, etc. directly into the container in a drip-type manner by pouring hot water into the container. In particular, this invention relates to a filter that has been improved so that the base, which is the main body of the filter, can be stably and quickly placed and fixed on a container.

A simple disposable filter that is fixed on a container and allows the coffee liquid to be directly received by pouring hot water into the container is known, for example, from Japanese Utility Model Publication No. 52-2703.

In this conventionally proposed filter, bent support pieces are formed through folds on both sides of a support plate having a pouring hole in the center, and projecting pieces are connected to the edges of the support pieces. At the same time, the outer periphery of a bag made of filter paper is attached to the back surface of the periphery of the pouring hole,
When using this, the bending support piece is bent downward at the crease, its edge is brought into contact with the opening edge of the container, and at the same time, the protruding piece is inserted into the inside of the opening edge and locked. It can be placed on top of the container.

However, since this known filter simply engages the projecting piece provided at the edge of the support piece into the container, it is not effective in positioning the support piece on the edge of the container or preventing it from shifting laterally. However, because it lacks cohesiveness and integrity with the container, there was a risk of it falling off the edge of the container's opening.

Especially since the filter is mainly made of paper etc.
The insertion of the protrusions mentioned above is sufficient for placing only the filter, but when coffee powder is put into the bag and then hot water is poured into it, the weight increases and the amount of hot water increases. Due to the impact of falling during injection, it could not be supported by inserting protrusions, and there was always a risk of falling.

This instability in filters is a common problem not only in the above-mentioned known filters but also in simple filters of this type, and a solution to this problem has been strongly desired.

The present invention was devised based on such requests, and includes a U-shape, U-shape, or V-shape (hereinafter collectively referred to as It is called a U-shape.

), the tongue-shaped inner clamping piece and the band-shaped outer clamping piece are integrally formed by this notch, and when the container is placed on the container, the inner and outer clamping pieces are used to open the container. An object of the present invention is to provide support leg pieces for a filter that can be stably fixed to a container by sandwiching the edges from the inside and outside.

Hereinafter, the features of the present invention will be described in detail based on an embodiment illustrating the present invention. In FIGS. 1 to 4, 1 is a support base that becomes the main body of the filter, and 2 is a support base that extends symmetrically from this support base. 3 is a filter paper bag attached to the lower surface of the support base.

The support base 1 and the support leg pieces 2 are made of cardboard or plastic sheets having the required rigidity.

In the embodiment shown here, the support base 1 and the support leg pieces 2 are made by cutting a piece of cardboard into a horizontally long rectangular shape, and placing the support base 1 in the center and the support leg pieces 2 on the left and right sides. These are then integrally formed.

In this cutting and forming process, a pouring hole 4 is punched out in the center of the support base 1, and a plurality of pouring holes 4 are formed symmetrically at the boundary between the support base 1 and the left and right support legs 2 around this pouring hole. An auxiliary line 5 for bending the book is carved, and the left and right supporting leg pieces 2.2 are punched out to provide approximately U-shaped notches 7, 7 near each leg end 6, 6. be.

The notches 7, 7 have a symmetrical shape on the left and right, and the formation of these notches allows a tongue-shaped inner clamping piece 8 to be formed on both support leg pieces.
A band-shaped outer clamping piece 9 is provided.

These clamping pieces 8 and 9, which are made up of a pair of inner and outer pairs, engage the leg ends of the supporting leg pieces 2 and 2 with the opening edge of the container to stabilize the filter when it is placed on a container 10 such as a coffee cup, as will be described later. This is to fix the support leg in the same position, and under normal conditions, each clamping piece is placed on the same plane as the supporting leg piece.

On the other hand, the filter paper bag 3 attached to the lower surface of the support base is made by folding a rectangular filter paper in half at the center as shown in FIG.
Furthermore, the two folded pieces are folded outward at each central portion, the overlapping edges of the two pieces are joined together to form the bag portion 11, and the outwardly folded pieces are attached to the adhesive piece 12, 12, and can be assembled integrally by attaching the adhesive pieces 12.12 to the lower surface of the base 1 formed together with the left and right support leg pieces, and pasting each peripheral edge part 13 of the adhesive pieces 12.12. .

The filter paper bag 3 shown here is shaped horizontally and has an adhesive piece 12.
．． The right and left sides of 12 are attached so as to straddle the lower surfaces of the supporting leg pieces 2, 2.

The present invention is constructed as described above, and when using the filter, which is composed of the base 1, the supporting leg pieces 2, 2, and the filter paper bag 3, first the left and right supporting leg pieces 2, 2 extending flat are attached. Curve or bend downward to transform it into an upright shape.

Next, the leg ends 6, 6 of the support leg pieces 2, 2 are placed facing the opening edge of the container 10, first the band-shaped outer clamping piece 9 is placed on the outside of the opening edge, and then the leg ends 6, 6 are placed opposite to this outer clamping piece. Inner clamping piece 8
is inserted into the inside of the opening edge of the container to sandwich the opening edge of the container from the inside and outside, the leg ends are fixed, and the container is placed in an upright manner on the container.

Figures 3 and 4 show the state in which the filter is placed on the container, that is, the state in which the supporting leg pieces are fixed. Since the clamping pieces 9 are pushed outward and outward from their flat state when clamping the edge of the container, the restoring force of the material acts on them and they can firmly clamp against the opening edge of the container.

And an inner and outer clamping piece 8 that clamps the opening edge of this container,
9, the inner clamping piece 8 engages shallowly inside the container, while the outer clamping piece 9 engages deeply to the outside, and the tip of the inner clamping piece 9 engages directly with the container as shown in FIG. Since the portion 8a and the inner edge 9a of the outer clamping piece face each other inside and outside the container, firm clamping can be achieved even though the clamping pieces are bifurcated from a flat state. In addition, since the outer clamping piece has a band shape and engages in a wrapping manner around the outer peripheral surface of the container, stable fixation can be obtained.

Moreover, when the support leg piece 2 of the present invention clamps the edge of the container 10 with the inner and outer clamping pieces 8°9, both ends of the notch 7? a, 7
Since the support leg piece a is brought into contact with the edge and the support leg piece is supported at two points in the front and back, the support base 1 can be kept in a stable state.

The filter placed and fixed on the container in the above manner is the base 1.
By pouring the required amount of coffee powder into the pouring spout and pouring hot water into it, the extracted coffee liquid can be received directly into the container.

FIG. 5 shows another embodiment of a simple filter according to the present invention in which the shape of the filter body is different.

The filter shown here has a support base 20 in a cylindrical shape, and the opening edge of a funnel-shaped filter paper bag 21 is attached to the inner wall surface of the support base 20 to be integrally attached. A pair of support leg pieces 22, 22 are provided so as to extend.

The supporting leg piece 22 is shaped like a plate as in the previous embodiment, and has a substantially U-shaped notch 23 formed near the leg end, and a tongue-shaped inner clamping piece 24 formed by this notch is used to hold the container 25. The band-shaped outer clamping pieces 26 are placed on the inside of the opening edge and attached to the outside, and clamped from the inside and outside, and both ends 23av of the notch are attached.
It is fixed on the container by abutting 23a on the opening edge.

In this way, the supporting leg piece is constructed in exactly the same manner as in the previous embodiment, and as a result of being held by the inner and outer holding pieces 24 and 26, the opening edge of the container is gripped and fixed from the inside and outside, and as a result, the rising state of the supporting leg piece is prevented. It is possible to maintain the support base in a stable state.

Therefore, even if coffee powder is put into the filter paper bag and hot water is poured in, the leg ends will not come off and the bag will not fall.

As above, the present invention has been explained with reference to each of the embodiments, but the supporting legs of the present invention are filters made of cardboard, plastic sheets, etc., and when the supporting legs are made of the same material, It can be commonly applied and, despite its simple shape, exhibits extremely stable bonding and fixing properties.
