[0001] The invention relates to means designed to facilitate protection of fragile objects
against shocks, vibrations, and other causes which might impair the integrity of the
objects.
[0002] The shock absorbing means to be described in greater detail below is characterized
by its simple structure, modest production cost, and efficiency in use as it provides
for complete isolation from the effects of shocks, vibrations, and the like to which
fragile objects normally are exposed during transportation and temporary storage.
[0003] In order that the invention may be clearly understood and readily carried into effect
an embodiment of a shock absorbing means for packing will now be described, by way
of example, with reference to the accompanying drawings, in which:
Fig. 1 is a side elevational partial view of a means according to the invention;
Fig. 2 is a longitudinal sectional view along line II-II in fig. 1, as seen from the
front;
Fig. 3 is a perspective view of the means according to the invention, embodied by
four identical portions;
Fig. 4 is a view of a fragile object packed by the embodiment of the means according
to the invention shown;
Fig. 5 is a presentation at right angles of one of the elements of shock absorbing
material of which the means according to the invention is composed in its interior.
[0004] The body of the shock absorbing means according to the invention forms a pocket 1
of rectangular shape, as seen from the side, and approximately oval in transverse
section. It is filled with a plurality of elements 2 of variable shape which, in their
preferred embodiment, have the configuration of an elliptical and curved piece, as
illustrated in fig. 5.
[0005] The faces 3 and 4 defining the pocket 1 are limited by lines 5 and 6 of welding or
fusing which extend in transverse direction across two strips or webs of laminar plastic
material, thereby defining narrow zones 7 between each pair of adjacent pockets 1.
[0006] The shock absorbing means specifically comprises an elongated band formed of a plurality
of pockets 1, as shown in fig. 3, to be arranged in such manner that it will wrap
an object 8 of fragile structure, either fully or in part, protecting it against shocks,
vibrations, or other causes of damage which might affect the object during its transportation.
In fig. 4 the shock absorbing means is shown applied to position an object 8 in the
interior of a box 9, the shock absorbing means acting as a wrapping in contact with
the various surfaces of the object to be protected.
[0007] The elements 2 are manufactured separately by suitable methods and preferably of
a porous and absorbing raw material, like expanded polystyrene, or any other material
which is light in weight and capable of mechanical, thermal, and acoustic absorption.
[0008] The dimensions of the pockets 1 may vary in correspondence with the envisaged dampening
or shock absorbing action and the size of the objects to be protected. They are made
in industrial lengths and cut to measure, as desired.
1. A shock absorbing means for packing, characterized in that it comprises a plurality
of housings (pockets 1) of enlarged, quadrangular shape and defined by transverse
lines (5,6) of welding between two laminar flexible strips of synthetic material,
connected by pairs of parallel welding lines and united along the borders, and in
that the housings are filled with elements (2) made of an essentially porous and absorbing
material and arranged arbitrarily.
2. The shock absorbing means as claimed in claim 1, characterized in that the elements
(2) of absorbing material have the form of curved sheets, preferably being of elliptical
shape, and in that the faces thereof form cells in connection with the pores of the
internal structure of increased surface area as compared to the volume.
