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 cover made of a fibrous cover material, particularly paper, and a handle, and a method for manufacturing the cover.

U.S. Pat. No. 3,528,236 discloses a frying pan cover consisting of a frame in the form of a cut tube with spoke-like partitions into which a cloth is inserted and stretched by an inner tightening frame.
It is known from the specification no. The removable attachment of the fabric to the support frame, in the form of attaching the fabric to a so-called embroidery frame, makes it easy to replace the fabric after it has been used as a frying pan cover, should it become infiltrated by fat that rises from the grilled meat. making it possible.

It has also already been proposed to make such a frying pan cover from a paper disc and paste this paper onto cardboard.

Also known from German Patent Application No. 2915274 is a cover with a retaining ring surrounding the paper, which retaining ring is cut out of a material such as cardboard with spoke-like radial arms and placed in place. and a radial arm running parallel to a plane, such as a sheet of paper, which is permanently connected to the radial arm. This cover has the advantage over other frying pan covers that, on the one hand, it can trap fats etc. without interfering with the flow of steam, and on the other hand, it is very simple to manufacture and handle as a consumable item. ing.

Particularly in the case of meat that has a very high liquid content and produces steam, the paper may ripple depending on the quality of the paper.
It was confirmed that this caused the entire cover to shrink.

Taking this fact into consideration, the object of the invention is to provide a cover of the type mentioned at the outset, which can be made particularly easily and which, due to its high dimensional stability even in the case of high moisture formation, can be used even 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 purpose is achieved by ensuring that the vapor-permeable surface of the plate-like cover has cross-reinforcement (dense)
at least partially bounded by a region;
This reinforced region is formed by impregnating the overmaterial with a synthetic resin additive. This is achieved in particular in that holes in the overmaterial serve as mating recesses for the plastic additive.

According to another feature of the invention, this reinforced area has a greater bending strength compared to the vapor permeable surface;
The disc-shaped cover as a whole thus provides a dimensional stability that allows it to be provided on the frying pan as described above.

Advantageously, the reinforcing area is provided as strips, one of which possibly has a handle.

This cross-shaped or lattice-shaped reinforcement cooperates as a reinforcement with the edging of the cover.

It is important that the reinforcing region of the overmaterial itself is not formed by strips of material attached to it, but is formed by the overmaterial itself reinforced with a curable additive; This additive is made of a curable synthetic resin with a softening point of approximately 200°C or higher.
It is also cellulophilic and therefore does not damage paper or fibers. Particularly useful for this purpose are two-component epoxy resins, which in the process according to the invention are applied to the overmaterial by an infiltration step or a steam step. It can also be provided on one side as well as both sides of the overmaterial.

The method according to the invention makes it possible to very easily produce a frying pan overcover which satisfies the requirements as a shield through which steam can penetrate and which traps rising fat, and which is easy to manufacture. It can be used as a consumable item. This feature makes the cover according to the invention patent no.
Advantages compared to the frying pan cover according to No. 3,528,236. That is, this known frying pan cover must be at least partially cleaned after each grilling process and is therefore not fully utilized by housewives.

Within the scope of the invention, a radial arm of a normal width, for example 20 mm, is provided with a reduced cross-sectional strength of the radial arm by at least one slit cut from its edge, so that the radial arm and the A further cover is also included, the adhesive strength of which is reduced at least to the extent that this cross-sectional strength is weakened. This procedure relaxes the frying pan cover in such a way that shrinkage no longer occurs, the load-relieving slits then causing a shape change in the radial arms, and a reduction in the adhesive force in this area assists the above-mentioned effect.

According to another feature of the invention, the radial arm is provided with at least two slits, each cut from opposite edges, running approximately parallel to each other and preferably at right angles to the lateral edges. running

This load-relieving slit works best if its length is greater than half the width of the radial arm, for example about 2/3 of the width of the radial arm.

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

The frying pan cover formed according to the procedure described above is large and has the desired dimensional stability.

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

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

A frying pan 1, in particular for frying pieces of meat 2, is covered by a rigid plate 3. This plate 3 is punched out of a fibrous paper strip B (FIG. 5) in an approximately circular shape, and from its outer periphery 4 protrudes a protrusion 5 (indicated by reference numeral 5 _S in another embodiment) as a handle. has been done.

The plate 3 has two reinforcing (densified) regions 10 in the form of mutually orthogonal strips in FIG. 1, which in the embodiment according to FIG. 2 run radially from the center point M of the plate. Between the reinforced regions 10 there is a superregion 7 .

The reinforcing regions 10 are formed by an infiltration step in which a liquid or vaporous curable additive 11, for example a two-component epoxy resin, is applied to the plate 3 in the area of each reinforcing region 10 (FIG. 4). The additive 11 partially penetrates into the paper of the board 3 and is tightly bonded to the paper by means of roots 13 that penetrate into the holes 12 thereof.

This reinforcing area 10, which is provided with additives 11 on one or both sides of the paper, is hardly noticeable in the finished board 3. In addition, in FIGS. 3 and 4, this reinforcing region 10 is shown in a straddling manner for ease of understanding.

FIG. 5 shows a manufacturing method, in which the incoming paper strip B is fed in its feeding direction
are provided, the average spacing a of the reinforcing regions 10 running at right angles being somewhat larger than the diameter d of the plate 3.

In FIG. 6, the plate 3 is the outer circumference 20 of the roll 21.
and a reinforced region 10 is produced during the rolling process. The additive 11 present on the roll periphery 20 is then transferred to the plate 3 and hardened after this step.

A manufacturing method in which the additive 11 is bonded to the material of the paper strip B or plate 3 by steam or spraying is not shown, but in this case also a thin strip for reinforcing the very thin plate 3 is used. occurs.

The synthetic resin additives mentioned above can be tightly bonded to paper through an infiltration process or a vapor deposition process;
It refers to all types of curable substances that are cellulosic and have a softening point above about 200°C.

In FIG. 7, a disc-shaped cover 30 with a radius r of, for example, 180 mm is placed on the edge 6 of the frying pan 1 where the handle 8 is provided.
0 has a cardboard holding plate 31 in which four sector areas 32 have been punched out, the remaining part of which has a border ring or holding ring 33 with a width e of 20 mm and a spoke-shaped integral radial An arm 34 is formed, which radial arm 34 articulates with a central region 35 of the retaining plate 31 at the disc center point M.

In FIG. 7, each of the two sector areas 32 located opposite to each other has one tongue piece 3.
9,40 are left, and these tongue pieces 39,4
0 is likewise punched out of the holding plate 31 during punching and is connected to its central region 35 by a narrow strip 41. The strip 41 is bounded on both sides by fold lines 42 and can be bent out of the disc plane E as shown in FIG.

One of the tongue pieces 39 is provided with an opening 45, and the tongue 44, which can be folded back about the fold line 43 of the other tongue piece 40, opens the opening 45 when the tongue pieces 39, 40 are folded back in FIG. It can be inserted inside. Since the width of the tongue 44 is greater than the width i of the opening 45, the two tongues 39, 40 are thus firmly connected to each other and form a loop-shaped handle.
In addition to or instead of this, in the embodiment described above, a handle projection 49 protrudes from the outer peripheral edge 48 of the retaining ring 33.

Beneath the retaining plate 31 or retaining ring 33 and its radial arm 34, a cellulose paper 22 is stretched or secured by a so-called squeeze weld connection, which paper 22 covers the sector area 32. , forming a superlayer here.

In FIG. 9 the slit 24 in the radial arm 34 is clearly visible, its length q being somewhat greater than half the width n of the radial arm 34.
In contrast to FIG. 9, FIG. 10 shows that there is very little adhesion between the radial arm 34 and the paper 22 at this location. That is, the line 25 indicates a narrow adhesive area 26, and the outside (area 27)
In this case, the paper 22 remains unattached.
