The pressing of the stiff walls edgewise to the
body of the wearer, with curved extent-conform
ing to the wearer’s body curvature gives requisite
intensity of pressure to hold the seal perfect. The
receptacle has the general shape of an elliptical
dome curved around the wearer’s body, with the
basal terminus of this dome extending or receding
without ceasing to be a part of the bulge or rise
of such a dome. In other words, there is no basal
These results are attained by making a shell of
45 sheet metal whose thin walls have shape approxi
mating that of the surface of a semi-ellipsoid.
These edges when in .use will terminate abruptly
against the wearer’s body. Instead of being cut
straight, as on the plane of the longitudinal axis,
their horizontal extent is concave, bowed out
ward with respect to that axis, to follow the hori
zontal curve of an abdomen. And at the ends of
the shell the edge line of up and down extent line,
as seen in projection on a vertical plane, is con
55 vex toward the wearer’s body, being bowed in
and there it applies pressure upward as well as 25
simultaneously inward against the wearer’s body.
The receptacle may be emptied in a convenient
and sanitary manner, without the belt falling out
of place, by holding the free unbuckled strap-end
on the wearer’s under-garment, with an ordinary gn
spring pinch clip, While the shell end is held in
hand' and tipped outward. Fresh lining may be
inserted While the shell is in this tipped position.
It is intended that the patent shall cover, by
suitable expression in the appended claims, what- 35
ever features of patentable novelty exist in the
invention disclosed.
In the accompanying drawing:
Figure 1 is an elevation showing a device em
bodying the invention applied at the abdomen of 40
a person;

the device of Figure 1 with the absorbent mate

Figure 4 is anelevation in section on v4--4 of
Figure 1, on an enlarged scale.
Referring to the drawing, the receptacle l0'
preferably will be a light-weight metal shell hav- 50
ing a modiñed semi-ellipsoid shape.
The edges
I2 of- the shell have the sharpness of a smoothly
cut piece of thin metal, so that under mild pres
sure these edges, all around the shell, embed
themselves rather deeply in a pad I4 which ab- 55
sorbently lines the interior of the shell and which
extends beyond the shell edges. 'l‘his pad is rela
tively soft, for constituting a cushion between
the sharp shell edges and the body of the person
using the appliance; and its sharpness favors its
deep seating in the cushion with consequent eii'ec
tiveness of sealing under a pressure which need
_ be only gentle.
The shell preferably has length considerably
lo greater than its width, and is arranged for its
longer dimension to extend horizontally in direc
tion around the wearer’s body. 'I'he upper and
lower edges have a concave aspect when viewed
from above, because they recede medially toward
the crest of the bulge, for approximately fitting
the curvature of the abdominal region of a per
son’s body.
'I‘he short up and down edges at
the ends of the shell have a 'convex aspect, when
viewed in elevation, because medially they ex
tend further from the crest of the bulge in order
to reach and to press firmly the abdominal wall,
which wall recedes as it proceeds laterally around
the person. 'I'he described stiffness with approxi
mation of actual ilt to body shape, coupled with
25 the stiifness of edges, permits the edges to be
_pressed deeply linto the pad, about equally all
the way around, under mild pressure applied' by
the narrow part of the wearer’s body, draws the
receptacle firmly upward and inward tightly
against the soft round surface of the abdomen.
Nevertheless, by a mere loosening of the belt, it
may be conveniently manipulated on and around
the belt, for disposal of contents and for the
inserting of a fresh lining pad. ’I'his manipula
tion is facilitated by the fact that the belt en
gages the receptacle low down on its under slope,
permitting a. tilting of the receptacle outward over 10
the loosened belt as a sustaining pivot. Yet
these conveniences afforded for this operation de
tract nothing from the effectiveness and safety
of the device when the belt is tightened against
the wearer’s body. The cooperative eifect of the 15
shell edges bedded in the soft pad material assure
safety of sealing with a minimum of discomfort.

shell, whose basal edge appears approximately 20
