suitable liquid-impervious, nonconductive plastic material.
The annular elements 7:6 and 27 are further each sub
stantially iden-tical to «the annular side walls 22 and 2.4 of
70 the cups 19 and 2.0, `for a purpose appearing presently.
In assembly, the annular elements 26 and 27 are re
spectively arranged interiorly and exteriorly of the tube
11 at the upper region thereof, so that the upper tube
end region 28 is interposed between the annular elements
26 and 27. That is, the annular elements 26 and 27 are
each of a downwardly tapering or conical configuration
so as to nest one within the other in the same manner
as the cup side walls 22 and 24. The upper end region
28 of the tu-be 11 is preferably formed with a plurality of
through apertures or holes 29 located between the nesting
elements 26 and 27. The annular elements are each
secured to the upper tube-end region 23 by suitable ad
hesive or plastic-welding means, and are preferably fur
ther secured to each other through the openings 29.
In this condition, the annular elements 26 and 27 ñrmly
sandwich therebetween the upper end-region 28 of the
tube 11 «to eñectively reinforce the upper end of the tube.
Also, a pair of apertured tabs or eyes 30 may be arranged
in diametrically opposed relation each having one end
securedly embedded between the annular elements 26 and
27, as shown in FIGURE 2. The tabs 30, thus securedly
anchored, serve admirably Well for attachment to a
handle, rope or bail.
The instant bucket or receptacle may be employed in
the same manner as conventional linemen’s tool buckets.
However, the present construction may be more easily
cleaned, as by mere wiping with a damp cloth. This
