DE60111819T2 - Can body made of metal - Google Patents

Abstract

Metal can body, the outer surface of which is provided with a regular pattern of mutually alternating relatively rough and relatively smooth zones which are mutually adjacent with smooth transition zones such that the visual illusion is created of mutually alternating convex and concave zones and optionally a tactile selectivity, according to which the relatively rough zones and the relatively smooth zones cause different touch sensations.

Description

techniques are known, with which one generally a very thin-walled can body a regular pattern from adjacent alternating convex and concave surfaces can give a so-called transformation process. Such a Shaping can take a very varied form and generally serves a pure aesthetic and not for a technical purpose (see eg EP-A 0 492 860).

It For example, indentations that extend in the longitudinal direction, more or less spirally extending indentations, indentations in the form of honeycombs, in the circumferential direction extending indentations, etc. known. It should be recognized that these indentations are generally have a concave shape, with convex surfaces that are more on the outside are localized, alternate, such. B. the relatively narrow demarcation zones between the recesses described.

It The object of the invention is to provide a can body make the described aesthetic Embodied effect without a relatively complicated and mechanically expensive production, such as B. the transformation process is necessary for this purpose. Another object of the invention is the production process for producing a can body so that it can be easily modified to a to make another pattern.

The considering the above tasks the invention provides a metal can body, the outer surface of a uniform pattern from adjacent alternating relatively rough and relatively smooth surfaces, which are mutually contiguous with smooth transition zones, so that the optical illusion by mutually alternating convex and concave Zones and optionally tactile selectivity is generated, according to the relative rough zones and relatively smooth zones different touch sensations cause.

It It has been found in tests that the can body according to the invention has a surprising Effect on the unsuspecting User has. On the basis of his visual perception he will, if he a can body picks up a mechanical pattern of zones that feel more indented and further outside are localized, expect. Once the user has accessed, he will realize that the recognized pattern is only an optical one Illusion is. This is an exceptionally surprising Effect and thus a very attractive aspect of the invention.

The possible tactile selectivity also requires a kind of "shape illusion", which is not based on visual Aspects, but more on touch sensations based.

One specific embodiment has the special property that the can body by pressing the top said outer surface against a shaping wall that has a corresponding surface structure how the pattern has been made.

One another embodiment has the special property that the pattern is attached to a slide that's around the can body is attached around.

These last variant can z. B. be embodied by the fact that the film attached to the outer surface of the can body is.

One preferred embodiment has the special property that the film is a shrink wrap, which due to shrinkage around the body corresponding increase in temperature is arranged. In this embodiment There is no seam, which contributes to the quality of the can body.

In some conditions could this aesthetically or for technical reasons for the can body desirable be, in addition with a pattern of convex and concave zones corresponding to Patterns available to be asked.

The The invention also includes a can body of the type described Type with a connected or integrated floor.

The The invention also relates to a can body of the type described Type with an associated or integrated floor, a filling and a lid.

Claims (10)

A metal can body, characterized in that the outer surface of the can body is provided with a regular pattern of mutually alternating rough and smooth surfaces which are mutually adjacent smooth transition zones, so that the optical illusion of mutually alternating convex and concave zones and optionally Tasttrennschärfe arises, according to the relatively rough zones and the relatively smooth zones cause different touch sensations. The can body according to claim 1, wherein the can body is made by forming the outer surface by pressing against a forming wall provided with a structure corresponding to this pattern. can body according to claim 1, wherein the pattern is arranged on a foil, around the can body is arranged. can body according to claim 3, wherein the film adheres to the outer surface of the can body. can body according to claim 3, wherein the film is a sleeve made of shrink film, around the body by a shrinkage process by a corresponding increase in temperature is arranged. can body according to claim 1, wherein the can body with a lacquer layer is covered, in which the relatively rough surfaces by a Krakelée - similar varnish layer are conditional. can body according to claim 1, wherein the can body with a printed pattern is covered. can body according to claim 1, comprising a pattern of convex and concave zones, which correspond to the above-mentioned pattern. can body according to one of the preceding claims, equipped with a bottom, who is connected or integrated with him. can body according to one of the claims 1-8, the with a floor connected or integrated with it, and a filling and a lid is.
