Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a plate-like cover for a container, such as a frying pan, having a vapor-permeable filtration surface and a handle made of fibrous filter material, particularly paper, and a method for manufacturing the cover.

U.S. Pat. No. 3,321,236 discloses a frying pan cup that consists of a frame in the shape of a cut pipe and has spoke-like partitions, into which a furnace cloth is inserted, and the inner fastening is stretched by the frame. Known by the specification. This removable attachment of the oven cloth to the support frame, in the form of attaching the fabric to a so-called embroidery hoop, makes it possible to replace the oven cloth in the event that the fat that rises from grilled meat has penetrated the oven cloth after it has been used as a frying pan cover. making it possible to do so.

It has also been proposed to make such frying pans from discs of filter paper and to attach the filter paper to cardboard.

Furthermore, in West German Patent Application No. 3274L, a cutter is known which has a retaining ring surrounding the paper receptacle, the retaining ring being formed from a material such as cardboard in a spoke-like radial direction. A cutout with an arm running parallel to the plane of the filter paper or the like is permanently connected thereto and to the radial arm. This cool-
Compared to other frying pans, it has the advantage of, on the one hand, being able to capture fats etc. without interfering with the flow of steam, and on the other hand, being very simple in production and handling as a consumable item. ing.

Especially when it comes to meat that has a very high liquid content and produces steam.
It was confirmed that the filter paper undulates depending on the quality of the filter paper, and this causes the entire cummer to shrink.

Taking this fact into consideration, the object of the present invention is to provide a cutlet of the type mentioned at the outset, which can be produced particularly easily and which, due to its high dimensional stability even in the case of high moisture content, can be used after one use. The idea is to make it so that it can be thrown away as a cheap consumable item.

According to the invention, this object is achieved in that the vapor-permeable surface of the plate-like cover is at least partially bounded by a reinforced (dense) region in the filtration material, which reinforcement region contains a synthetic resin additive in an interlocking connection with the filtration material. This is achieved in particular in that the holes in the filter material serve as mating recesses for the synthetic resin additive.

According to another feature of the invention, this reinforcing area is made to have a high bending strength compared to the vapor-permeable surface, so that the disc-shaped cover as a whole is shaped such that it can be provided on the flynocene as described above. Produces stability.

Advantageously, the reinforcement 1 is provided as strips, one of which possibly has a handle.

This cross-shaped or lattice-shaped reinforcing section acts cooperatively as a reinforcing body by means of the cut edges.

It is important that the reinforced area of the filtration material itself is not formed by strips of material attached to it, but rather by the filtration material itself reinforced by a curable additive; It is made of a curable synthetic resin with a softening point of about 200° C. or higher, which is also cellulosophilic and therefore does not damage the F paper or fibers. Particularly useful for this purpose are two-component epoxy resins, which in the method according to the invention are applied to the filter material by an infiltration step or a vapor deposition step. It can also be provided on one side as well as both sides of the filter material.

The method according to the invention makes it possible to very easily produce a frying pan filtration cup that is permeable to steam and satisfies the requirements as a shield for trapping rising fat. It can be used as a consumable item for manufacturing purposes. This feature gives the frying pan according to the invention an advantage over the frying pan frying pan according to US Pat. No. 33;21,234. That is, this well-known 7-year-old pancake must be at least partially cleaned after each grilling process, and therefore cannot be utilized at all by housewives.

Within the framework of the invention, it is provided that the radial arm of ordinary width, for example 2011A, is weakened by at least one slit cut from its edge, and the adhesive connection between the radial arm and the filtering surface is at least this Also included are other clicks that are reduced in the weakened range.

This procedure relaxes the fly-nosed jacket so that contraction no longer occurs, the load-relieving slits then causing a shape change in the radial arms and a reduction in the adhesion forces in this area aiding the above-mentioned effect.

According to another characteristic of the invention, the radial arm is provided with at least two slits, each of which is cut from opposite edges and runs substantially parallel to each other, tX;
Preferably it runs at right angles to the side edges.

This load-relieving slit works optimally if its length is greater than half the width of the radial arm, for example about 7 times the width of the radial arm.

The radial arm is not connected to the FM in the region of the slit in a gluing process, or only at the elongated strip, this latter embodiment also being sufficient to produce an unhindered movement of the radial arm.

The 7-raipan canoes formed based on the above-described procedure are large and have the desired shape stability, as confirmed by actual experiments.

According to another feature of the invention, the radial arm and the support ring are connected to the p-paper by a so-called squeeze weld connection.

The present invention will be described in detail below based on embodiments shown in the drawings.

Particularly for frying pieces of meat)Rnl is a rigid door plate 3
covered by. This furnace plate 3 is made of fibrous strip Fg.
A substantially circular shape is punched out from B (FIG. 5), and a projection j (indicated by reference numeral j8 in another embodiment) protrudes from the outer peripheral edge thereof as a handle.

The oven plate 3 has two mutually orthogonal strip-shaped reinforcement (dense) regions IO in FIG. 1, which in the embodiment shown in FIG. . Between the reinforced regions 10 there is a filtration zone 7 .

The reinforcing regions IO are formed by an infiltration step in which a liquid or vaporous curable additive//for example a two-component epoxy resin is applied to the door panel 3 in the area of each reinforcing region 10 (FIG. 3).

The additive /l partially penetrates into the paper 2 of the door plate 3 and is tightly bonded to the filter paper by means of the roots 13 that penetrate into the holes /2.

This reinforcing area IO, which is provided with additive/l on one or both sides of the filter paper, is hardly noticeable in the finished door panel 3. In addition, in FIG. 3 and FIG. q, this reinforced region io is shown in an exaggerated manner for ease of understanding.

FIG. 5 shows a manufacturing method, in which the fed filter paper strip B is provided with a reinforcing region 10 in its feeding direction The average spacing a of the regions IO is somewhat larger than the diameter d of the oven plate 3. In Figure 1, the door plate 3 is fed against the outer circumference 3 of the roll 2/, and reinforcing areas 10 are produced during the rolling process. At this time, the additive // present on the outer circumference m of the roll is transferred to the oven plate 3 and hardened after this step.

A manufacturing method in which the additive/l is bonded to the material by vapor deposition or spraying on the filter paper strip B or the door plate 3 is not shown, but in this case as well, the furnace plate 3 is very thin.
A thin strip is created to reinforce the

Regarding the aforementioned synthetic resin additives, all types of curable substances that can be tightly bonded to the filter paper by an infiltration process or a vapor deposition process, are cellulosic, and have a softening point of about 200°C or higher. It means.

In FIG. 7, on the edge 6 of the fly/zone l where the handle t is provided, there is placed a disc-shaped cover 30 with a radius r of, for example, The remaining part of this holding plate 31 has a width e of y′l1JN.
as well as a spoke-like integral radial arm 3tA, which is articulated at the disc center point M in the central region 3S of the retaining plate 3/.

In FIG. 7, each of the two sector areas 3 which are located opposite to each other has one tongue-shaped tongue piece 39. ? -0 is left behind, these tongues 39. The rib e is likewise punched out of the holding plate 31 during punching and is connected to its central region 3S by a fine strip lit/. Its strip part ψ
/ is bounded on both sides by crease lines t2 and can be bent out of the disk plane E as shown in FIG. r.

One tongue piece 39 is provided with an opening aS, and the tongue piece 39 in the figure is provided with a tongue piece that can be folded back about the fold line 'A3 of the other tongue piece. In the folded state of the case, it can be inserted into the opening ψS. Since the width of the tongue bowl is larger than the width 1 of the opening 5, both tongue pieces Jq,
'to are tightly connected to each other to form a loop-shaped handle. In order to supplement or replace it, a handle protrusion 9 protrudes from the outer peripheral edge q4 of the retaining ring 33 in the embodiment described above.

Below the retaining plate 31 or retaining ring 33 and its radial arm, there is a cellulose filter paper U.
The filter paper 24 is stretched over or fixed by means of a so-called squeeze weld connection and covers the three sector areas and forms a filter layer there.

Radial arm in Figure 7? Slit J at ψ
is clearly shown and its length q is the radial arm 7
It is somewhat larger than half of the width n of μ. Unlike the figure 7,
Figure 0 shows that the adhesion between the radial arm profile and the filter paper n at this point is very slight.J or line j indicates a narrow adhesion area, U, outside of which (area 27 )
So, I still can't get pasted on P paper N.
