"Stackable plates and the like"

The innovation relates primarily to thermoforming Manufactured plates, bowls, flat parts and the like made of thin-walled material with a stacking attachment that allows easy separation of the stacked parts.

Especially with plates or other flat parts made of thin plastic film, it is difficult to create a light To achieve destacking.

If the parts are designed in such a way that they lie close to one another without a stacking device, that is, without any spacing from one another, so the separation is made more difficult by the fact that it is difficult to touch the edges and that the adhesion of the closely spaced Share the pull force increased.

If, on the other hand, there is a stacking device, as it is for example is common for thin-walled cups and other containers,

characterized by undercut areas on the bottom or on the peripheral edge,

on the one hand the stack of containers is very high, since this stacking reaches a multiple thickness of the film and on the other hand it is this type of pile is very delicate.

That is, it leads to jamming or locking of the parts, whereby the isolation is considerably impaired.

In contrast, it is the purpose of the innovation to create a possibility that such flat parts in only a small distance can be safely stacked to one another and easy unstacking is guaranteed.

According to the innovation, this is achieved in that the parts are positioned at as flat a point as possible on the bottom or the peripheral edge or part of the side wall a short cylindrical one Have a paragraph, which consists of about twice the film thickness of the part.

Such a stacking step can be produced, for example, by thermoforming as follows:

“While the plate is being formed, a about 1-2 mm deep cylinder formed and immediately afterwards again from a piston, which is about 4 i'olien strengths in Diameter is smaller, repelled. This creates a circumferential bead that rests on the floor or edge etc. of the underlying part a firm hold and thus enables good stacking and unstacking.

Examples of the innovation are shown in the following figures in the attached drawings:

Figure 1 Lvei stacked plates with a slightly conical outer edge and with the new stacking device on the outer edge of the base in half section

Figure 2 Two: stacked flat shells with an approximately horizontal one Peripheral edge, where the new stacking device is located in the peripheral edge, also in half-cut,

Figure 3 Two stacked plates or bowls with a step-shaped Edge part, in the approximately horizontal step of which the new stack paragraph is located, also in the Half cut.

Figure 1 shows a known plate 1 for single use made of deep-drawn plastic film, consisting of a Circumferential bead or edge 2, a slightly conical edge part 4 and a base 3.

At the outer edge of the roughly flat bottom 3, i.e. before the Transition to edge part 4, there is stacking paragraph 5-Diesel ' Stapelabsö.tz 5 consists of a fold of the material of plate 1 and thus has twice the film thickness.

FIG. 2 differs in that the stacked shoulder is not located on the bottom 13 of the part 11, but on the outer edge 12 of the shell 11.

Figure 2 shows a plate or a flat bowl 21, consisting of a bottom 2Ξ and an outer peripheral edge 22, whose side wall 2Ί is interrupted by a step 26 and on this the stacking paragraph 25 is located. All of the features mentioned can also be combined with one another as required.

Claims (1)

Protection claims: Stackable containers such as plates, bowls or the like with a conically widening wall and one
outer edge, in which a bead-like stacking device in an outer, as flat as possible area
is appropriate characterized in that this pile bead by
a fold of the wall area, that is to say approximately twice the film thickness on the bottom: is. Flat part according to claim 1,. characterized in that the stacking bead is on outer edge is located. Flat part according to claim 1, characterized in that the stacking bead is located in a shoulder of the side wall. Flat part according to claims 1-3, characterized in that the stacking bead also opposite, so can be shaped upwards.
