Elastic Packing Material, Envelope or Mat for all kinds of Objects.
I, GUSTAV LESKE, of Berlin, in the Empire of Germany Manufacturer, do hereby
declare the nature of this invention to be as follows:
A packing material or protective envelope for cylindrical and other objects, such
as bottles and other fragile objects, has been employed consisting of paper or paste
board bent into corrugated form, one side of the corrugated material being secured
to a flat or non-corrugated sheet, so that its other side presents rounded rib-like
projections, which are of a soft or yielding nature but are not to any extent elastic.
My present invention relates to an improved manufacture of such packing
material or protective envelope which possesses considerable elasticity, and which
consists on the one hand in dispensing with the flat sheet which has heretofore been
used as attachment for the corrugated material, and, on the other hand, in imparting
to the corrugations or ribs such a peculiar sectional form, as to afford to them the
required elastic action. For this purpose the corrugations or ribs are SO
formed that the tops or ridges of the corrugations overhang the sides thereof, so
that their cross section is of a dovetail form, the sides being thus made to assume
a more or less inclined position, and the ridge and sides being either more or less
flat, or curved.
If the ridges are made comparatively flat, the packing material or envelope will
present generally the appearance of a thick flat sheet with grooves at intervals, such
grooves being of greater or less width, according as the ridges are made to over-
hang the sides to a greater or less extent. This material will not only afford con-
siderable elasticity as an envelope for fragile objects, but also, owing to its more or
less flat surfaces it can be used with advantage as a mat for placing objects upon,
and it is for this purpose capable of being ornamented with designs.

I, GUSTAV LESKE, of 70, Blumenstrasse, Berlin, in the Empire of Germany,
Manufacturer, do hereby declare the nature of this invention and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement: -
A packing material or protective envelope for cylindrical and other objects, such

page_text: as bottles and other fragile objects has been employed consisting of paper or paste
board bent into corrugated form, one side of the corrugated material being secured
to a flat or non-corrugated sheet, so that its other side presents rounded rib-like
projections, which are of a soft or yielding nature but are not to any extent elastic.
My present invention relates to an improved manufacture of such packing
material or protective envelope which possesses considerable elasticity, and which
consists on the one hand in dispensing with the flat sheet which has heretofore been
used as attachment for the corrugated material, and, on the other hand, in imparting
to the corrugations or ribs such a peculiar sectional form, as to afford to them the
required elastic action. For this purpose, the corrugations or ribs are formed as
I shall describe referring to the accompanying drawings.
Fig. 1 is a section of part of a sheet corrugated according to my invention. Fig.
2 is a section shewing a form somewhat modified, Fig. 3 is a plan with section shew-
ing a sheet with its dovetailed corrugations, Fig. 4 shews a corrugated sheet
wrapped round a cylindrical article, Fig. 5 shews a mat made of the corrugated
material.
The corrugations are of the form of box pleats, their tops or ridges overhanging
the sides thereof, so that their cross section is of a dovetail form, the sides being
thus made to assume a more or less inclined position, and the ridge and sides being
either more or less flat as in Figs. 1 and 3 or curved as in Fig. 2.
If, the ridges are made comparatively flat, the packing material or envelope will
present generally the appearance of a thick flat sheet with grooves at intervals as
shewn in Fig. 3 such grooves being of greater or less width, according as the ridges
are made to overhang the sides to a. greater or less extent. This material will not
only afford considerable elasticity as an envelope for fragile objects as shewn in
Fig. 4, but also, owing to its more or less flat surfaces it can be used with advantage
as.a mat as shewn in Fig. 5 for placing objects upon it, and it is for this purpose
capable of being, ornamented with designs.
Having now particularly described and' ascertained the nature of this invention
and in what manner, the same is to be performed, I declare that what I claim is:-
An elastic packing material, envelope or mat consisting of paper or paste board
having corrugations of box pleat form, their ridges being flat or curved and more
or less overhanging the sides in dovetail form, substantially. as described.
