In FIG. 6 shows an embodiment when the positioning element is created by a part of the moisture-permeable container.

Hereinafter, for ease of perception, the rigid circuit is referred to as the “circuit”, and the moisture-permeable container is referred to as "capacity".

This invention describes a method (options) for the manufacture of a disposable infuser with a bend and an extraction system.

The method consists in the fact that the circuit and the container are interconnected in a fixed manner, and the squeezing mechanism is attached to the device while maintaining the freedom of movement of the squeezing part. The threads must be free to move for spinning, and are fixed by no more than one end by attaching to any part of the device or are held in position by a holder on the end of the thread, which is larger than the size of the hole through which the thread passes and does not allow it to pop out devices. The contour has at least one layer, the container minimally consists of one layer and one workpiece, the squeezing mechanism consists of at least one thread.

The sieve is collected from pre-prepared blanks. The initial fragments of the sieve contour are flat blanks made of plastic, cardboard, laminated paper. The initial blanks for the container can be either flat - from nylon, cellulose, filter paper, or solid seamless convex, preformed or solid cast, i.e. having already the final form without folds, from cellulose, its derivatives and other similar polymeric materials. The threads of the squeezing mechanism may be woven or non-woven from polymer.

The sieve can be manufactured on a single machine with one stamp, when all the source parts are connected at the same time. All blanks are folded in layers between two planes b stamp and are connected with one stroke of the stamp. In this case, it is most convenient to use a seamless blank of the moisture-permeable part.

The sieve can also be made in several phases. Some parts of the sieve can be pre-assembled among themselves, and then in the final assembly connected to the rest of the sieve. This is effective in the case when several methods of joining the workpieces are used in production or such a distinction is more productively effective. For example, when the moisture-permeable part is assembled by heat sealing, and attached to the circuit by gluing or clamped between two layers of the circuit. Or, yarns and holders at their ends can be pre-assembled, which can be difficult when collecting sieves at one time. The moisture-permeable part of the sieve and the threads or the moisture-permeable part, the squeezing mechanism and the positioning pad may also be pre-connected.

The moisture-permeable part of the sieve may have one or more layers, and also be made of one or more blanks.

The execution of the container from one seamless blank by the edge assembly method allows the formation of a container in the form of a bag, i.e. not having a clear form. The use of a blank with a seam or several blanks allows you to form a container with a clear desired shape, and it is also possible when parts of the tank are not just connected, but superimposed on each other, allowing you to create hollow channels in the body of the tank in places of overlap (Fig. 1, 1A), in which the threads of the squeezing mechanism then lie. On figure 1 shows two flat blanks of the container. When assembling, they are superimposed on each other (Fig. 1 A), connecting at the seams 1 and overlapping with the fields 2. The places of overlap form a two-layer space in which the threads lie.

A path can have one or more layers. With a single-layer circuit, the capacitance is attached to the circuit from above or below, with a two-layer circuit, it is clamped between the layers of the circuit. In the case of manufacturing a three-layer contour, they are combined in layers: the first contour layer, the capacity layer, the second contour layer, the thread layer, the third contour layer.

Layers of the contour can both coincide in shape and size, and vary. For example, one layer may be smaller than the other in size. In FIG. 2 shows two layers differing in size and shape, in FIG. 2A they are combined, as in the final assembly.

FIG. 3 and 3A show a variant when two layers of a contour consist of several parts. In Fig. 3 two layers are shown, each of which consists of parts, and also they have their own fold lines 3 and 4. In FIG. A contour in the assembly is shown behind, with the contour having two fold lines.

Layers can also vary in shape, for example, when one layer has additional protrusions to hold the contour at the edges of the brewware.

To provide the contour with a bend line, workpieces with an already laid line can be used. In the case of using plastic, the line is made by reducing the thickness of the workpiece in the right place or with a strip of holes. In the case of using cardboard - cutting perforations, curly cutout, or may be marked by notching the top or bottom layer of cardboard.

The folding line can also be created during the final assembly by punching, a figured neckline, cutting perforations.

The fold line can also be performed by several methods simultaneously.

Layers of the contour can be both flat and embossed. A variant is possible when the threads of the squeezing mechanism pass through the body of the contour parallel to its plane. In this case, the contour has at least one layer with a corresponding relief, which when connected to another layer of the contour creates a hollow channel in the body of the contour for the passage of threads. The relief may have two layers symmetrically to each other.

The squeezing mechanism may consist of one or more threads. In case one thread is used, it is located on top of the body or in the body of a moisture-permeable container with a zigzag.

In case two threads are used, they are located with a cross linked by a cross (Fig. 4), symmetrically zigzag or not intersecting.

In the event that a sieve is produced where the threads are held in position on the surface of the container, this is done either by positioning the patch or by the thread penetrating the body of the container, piercing it. Figure 5 shows a variant where the threads 5 pass, without intersecting, through the body of the moisture-permeable container 6, piercing it.

It is possible that the threads are held at the expense of part of the container itself, which is a protrusion on the surface capacity, bends, passing over the threads, and then fastens with its end to the surface of the container, forming a positioning element (Fig.6).

There can be several positioning pads. They are attached to the surface of the tank by gluing or heat sealing.

If the patch is equal in size to the surface of the container, it is an analog of the layer of the container. At the same time, the patch necessarily joins in several places with the container in order to ensure the necessary distribution of threads on the surface of the container. The edges of the lining can go into the body of the contour.

The squeezing mechanism can be attached to the container without touching the circuit. The threads of the squeezing mechanism may be unfixed on the surface of the container, being attached to the pad, or in its body and ending with holders at the ends, leaving the body or from under the pad directly at the edge of the contour.

It is possible that the threads, passing through the body or in the body of the tank, pass through the body of the contour through holes or cuts perpendicular to the plane of the contour.

In those cases when the threads of the squeezing mechanism retain freedom of movement along the entire length and their ends are not fixed by anything, they are provided by the holders. Holders located at the ends of the threads are larger than the width of the strokes or holes through which the threads pass, and thus hold the threads, preventing them from popping out of position.

It is also possible that one end of each thread fixed and attached to the body of the tank or circuit. In this case, the presence of holders on the free ends of the threads is optional.

If the threads are made of fabric, the holders of plastic, cardboard or paper are attached to them. To simplify the production of threads can be made of food grade polymer with a thickening or expansion at the ends, acting as a holder.

The initial parts of the circuit are connected with each other and with the remaining parts of the sieve by gluing, pressing or by pressing one part into another.

The indentation method is possible when releasing parts of the contour from plastic. In this case, the upper and lower layers of the contour have a complementary relief, one layer during assembly is pressed into another and is held in it by friction. At the same time, those parts of the sieve that must be fixedly attached to the circuit are clamped between the layers of the circuit.

If the surface of the contour is used as an information carrier, the application of information is done before the assembly of the sieve.

The easiest to manufacture option is when the sieve is made with a two-layer contour, without a positioning pad, the squeezing mechanism consists of two intersecting threads. The threads pass along the outer surface of a single-layer container without being fixed to it, then pass through the body of the contour parallel to its plane and from both ends go outside, ending with holders. A bend line is drawn on the path when creating the workpiece.
