CLAIMS
Claims 20, 21, 23, and 27 are representative of the claims on appeal, and read
as follow:
20. Cold-formed shaped packaging which comprises a shaped packaging made
of a metal-plastic laminate with at least one packaging recess therein formed between a
retaining tool and a die exhibiting at least one opening, wherein the die and the retaining
tool feature facing edge regions and the die within the die edge region includes a
shoulder region that surrounds said at least one die opening, wherein the shoulder
region includes a surface thereof and the die edge region includes a surface thereof,
and the surface of the shoulder region lies 0.1 to 10 mm lower than the surface of the
die edge region, and at least one first stamp including a first friction forming surface
which pre-forms the metal-plastic laminate in at least one step up to 100% of the final
depth of the recess, and subsequently at least one second stamp including a second
friction forming surface which forms the pre-formed metal-plastic laminate in at least
one step to at least 100% of the final depth of the recess, wherein the first friction
forming surface has a higher degree of friction than the second friction forming surface,
and wherein said shaped packaging is free of folds.
21. Cold formed shaped packaging according to claim 20, characterized in that
the shaped packaging is made of a metal-plastic laminate containing in its make up
oPA 25 / Al 45 / PVC 60 or
oPA 25 / Al 45 / oPA 25 or
Al 120 / PP 50 or
oPA 25 / Al 60 / PE 50 or
oPA 25 / Al 60 / PP 60 or
oPA 25 / Al 45 / PVC 100 or
oPA 25 / Al 60 / PVC 60 or
oPA 25 / Al 45 / PE coated or
oPA 25 / Al 45 / cPA 25 or
oPA 25 / Al 60 / PVC 100 or
oPA 25 / Al 60 / oPA 25 / EAA 50
where oPA stands for oriented polyamide, cPA stands for cast polyamide, PVC stands
for polyvinylchloride, PE stands for polyethylene, PP stands for polypropylene, EAA
stands for ethylene-acrylic acid copolymer, and Al stands for aluminum and the
numbers for the thickness of the layer or foil in µm.
23. Cold formed shaped packaging according to claim 20, including a plurality of
recesses spaced apart from each other.
27. Cold formed shaped packaging according to claim 23, including a ratio of
diameter to height of said recesses of 2-3.
