PORTABLE COLLECTOR FOR DROPPINGS
Abstract
A readily-flexible, tear-resistant, bag-like receptacle has the
open end thereof telescoped along the outer surface of that
bag-like receptacle in a direction toward the closed end of that
bag-like receptacle to cause a portion of that bag-like receptacle
to lie in inverted condition over a further portion of that
bag-like receptacle and thereby form an opening-defining fold. A
manually-manipulable device is disposed at least partly inwardly of
the inverted-condition portion of the bag-like receptacle, it is
small enough to fit wholly within that bag-like receptacle, and it
can be opened to accommodate a dropping. Thereafter, the free end
of the bag-like receptacle can be telescoped along the outer
surface of that bag-like receptacle in a direction away from the
closed end of that bag-like receptacle and beyond the position
occupied by the opening-defining fold to dispose the
previously-exposed surface of the inverted-condition portion of
that bag-like receptacle wholly at the interior of that bag-like
receptacle.

Description
This invention relates to improvements in Portable collectors For
Droppings. More particularly, this invention relates to an improved
portable collector for droppings which is small enough to be held
in a user's hand but which can be used without causing any of the
droppings to contact that user's hand.
It is, therefore, an object of the present invention to provide an
improved portable collector for droppings which is small enough to
be held in a user's hand but which can be used without causing any
of the droppings to contact that user's hand.
The problem of disposing of droppings from pets and other animals
is a vexing and unpleasant problem. The present invention affords a
practical solution to that problem; and it does so by providing a
readily-flexible, tear-resistant, bag-like receptacle which can
have the open end thereof telescoped along the outer surface
thereof to lie in inverted condition over a further portion
thereof, and by providing a manually-manipulable device which is
disposed at least partly inwardly of that inverted-condition
portion and which is small enough to fit wholly within that
bag-like receptacle. That manually-manipulable device can be opened
to accommodate a dropping; and then the open end of that bag-like
receptacle can be telescoped away from the closed end of that
bag-like receptacle and can be closed to confine and enclose the
dropping, and also to leave all portions of the exterior surface of
that bag-like receptacle free of any traces of that dropping. It
is, therefore, an object of the present invention to provide a
readily-flexible, tear-resistant, bag-like receptacle which can
have the open end thereof telescoped along the outer surface
thereof to lie in inverted condition over a further portion
thereof, and to provide a manually-manipulable device which is
disposed at least partly inwardly of that inverted condition
portion and which is small enough to fit wholly within that
bag-like receptacle.
Other and further objects and advantages of the present invention
should become apparent from an examination of the drawing and
accompanying description.

Description of the Preferred Embodiments: Referring particularly to
FIGS. 1-9, the numeral 20 denotes a readily-flexible,
tear-resistant bag-like receptacle which normally has one end
thereof open. That bag-like receptacle will preferably be made from
an inexpensive, sturdy, readily-flexible, tear-resistant,
light-opaque, flexible material such as polyethylene or other film.
In using that bag-like receptacle, the normally-open free end 24
thereof will be telescoped along the outer surface of that bag-like
receptacle in a direction toward the closed end of that bag-like
receptacle until that open end is adjacent that closed end, as
shown particularly by FIGS. 2 and 6. The resulting folded edge of
that bag-like receptacle is denoted by the numeral 22; and the
resulting lapping of the portion of the exterior surface of that
bag-like receptacle, which is intermediate that folded edge and the
closed end, by the inverted-condition portion of that bag-like
receptacle will protect a substantial portion of that exterior
surface.
A protective pocket 26 is attached to the inner surface of the
bag-like receptacle 20 adjacent the folded edge 22, as indicated
particularly by FIGS. 2 and 9. That protective pocket has the
right-hand end thereof open; and a perforated tab 28 projects
outwardly from the upper edge of that open right-hand end. The
numeral 30 denotes a second protective pocket which is attached to
the inner surface of the bag-like receptacle 20 adjacent the folded
edge 22. The protective pocket 30 has the right-hand end thereof
open; and a perforated tab 32 projects outwardly from the upper
edge of that open right-hand end. A perforated web 34 extends
between the lower portions of the open right-hand ends of the
protective pockets 26 and 30, as shown by FIGS. 2, 6 and 9. The
protective pockets 26 and 30 will preferably be made from the same
type of material of which the bag-like receptacle 20 is made; and
the lower edges of those protective pockets will be heat-seamed,
cemented, or otherwise secured to the inner surface of the bag-like
receptacle 20 adjacent the folded edge 22.
The numeral 38 generally denotes a scoop which can be used with the
bag-like receptacle 20; and that scoop has a generally U-shaped
frame 40 which is preferably made from metal or stiff plastic. That
U-shaped frame has a flange 42 extending along one side edge
thereof to help stiffen it, and it has a second flange 44 extending
along the opposite side edge thereof to help stiffen it. An
upwardly-directed extension 46 is provided at the upper end of the
flange 44, as indicated by FIGS. 4 and 5; and a laterally-directed
ear 48 is provided at the upper end of the flange 42, as shown by
FIGS. 3 and 5. A generally-similar ear 49 is provided adjacent the
upper end of the flange 44; and the ears 48 and 49 have openings
therein which are aligned with each other and which define a line
that is parallel to the plane of the U-shaped frame 40. A
stiffening flange 50 is provided adjacent the bottom of the
rectangular opening which is defined by the U-shaped frame 40; and
stiffening flanges 51 and 53 are provided adjacent the sides of
that rectangular opening. An opening is provided in the upper end
of the flange 51 that is in register with the opening in the ear 48
adjacent the upper end of the flange 42; and an opening is provided
in the upper end of the flange 53 that is in register with the
opening in the ear 49 of the flange 44.
An ear 52 is provided on the U-shaped frame 40 adjacent the lower
edge of that U-shaped frame; and that ear confronts, but is spaced
laterally a short distance from, the flange 42. A similar ear, not
shown, is formed on the U-shaped frame 40 adjacent the lower edge
of that U-shaped frame; and that ear confronts, but is spaced
laterally a short distance from, the flange 44. Openings are
provided in the ear 52 and in its counterpart, and similar openings
are provided in the lower ends of the flanges 42 and 44; and those
openings define a second line which is parallel to the plane of the
U-shaped frame 40.
The numeral 54 denotes a second generally U-shaped frame; and that
frame will preferably be similar to the U-shaped frame 40. A flange
56 extends along one side edge of the U-shaped frame 54 to help
stiffen it; and that flange has an upwardly-directed extension 58,
as shown by FIGS. 3 - 5. A laterally-directed ear 62 is provided on
the flange 56 adjacent the upper end of that flange, as indicated
by FIGS. 3 and 5. A flange 60 extends along the opposite side of
the U-shaped frame 54 to help stiffen it; and that flange has a
laterally-directed ear 61 adjacent the upper end thereof which is
similar to the ear 48. Openings in the ears 61 and 62 are aligned
with the openings in the ears 48 and 49 of the U-shaped frame 40. A
stiffening flange 64 is provided adjacent the bottom of the
rectangular opening which is defined by the U-shaped frame 54; and
stiffening flanges 66 and 68 are provided adjacent the sides of
that rectangular opening. An opening is provided in the upper end
of the flange 66 that is in register with the opening in the ear 62
adjacent the upper end of the flange 56; and an opening is provided
in the upper end of the flange 68 that is in register with the
opening in the ear 61 adjacent the upper end of the flange 60.
Those various openings also are in register with the openings in
the upper ends of the flanges 51 and 53 and in the ears 48 and 49
on the U-shaped frame 40.
An ear 70 is provided on the U-shaped frame 54 adjacent the lower
edge of that U-shaped frame; and that ear confronts, but is spaced
laterally a short distance from, the flange 56, as shown by FIG. 4.
An ear 72 also is provided on the U-shaped frame 54 adjacent the
lower edge of that U-shaped frame; and that ear confronts, but is
spaced laterally a short distance from, the flange 60, as shown by
FIG. 4. Openings are provided in the ear 70 and in the ear 72, and
similar openings are provided in the lower ends of the flanges 56
and 60; and those openings define a second line which is parallel
to the plane of the U-shaped frame 54.
The numeral 74 denotes a pivot which extends through the opening in
the ear 48 on the flange 42 of the U-shaped frame 40, through the
opening in the ear 62 on the flange 56 of the U-shaped frame 54,
and through the openings in the upper ends of the stiffening
flanges 51 and 66. That pivot will coact with those openings to
permit the U-shaped frames 40 and 54 to rotate relative to each
other. A torsion spring 76 encircles that pivot and bears against
the upper edges of the U-shaped frames 40 and 54; and that torsion
spring urges those U-shaped frames toward the open position shown
by FIG. 3. However, that torsion spring can yield to permit those
U-shaped frames to be moved to the closed position shown by FIG. 5.
The numeral 78 denotes a pivot which extends through the opening in
the ear 61 on the flange 60 of the U-shaped frame 54, through the
opening in the ear 49 on the flange 44 of the U-shaped frame 40,
and through openings in the upper ends of the stiffening flanges 68
and 53. That pivot will coact with those openings, and also will
coact with the pivot 74 and the openings therefor, to permit the
U-shaped frames 40 and 54 to rotate relative to each other.
The numeral 80 denotes a pivot which is supported by the stiffening
flanges 51 and 53 of the U-shaped frame 40, and that pivot
rotatably supports a cylindrical handle 82. A pivot 84 is supported
by the stiffening flanges 66 and 68 of the U-shaped frame 54, and
that pivot rotatably supports a cylindrical handle 86. Those
handles are in register with each other, as indicated particularly
by FIGS. 3 and 5; and they can be gripped and urged toward each
other to overcome the force which is provided by the torsion spring
76. As a result, the handles 82 and 86 can be used to move the
U-shaped frames 40 and 54 from the open position of FIG. 3 to the
closed position of FIG. 5.
A flexible restraining element 88, such as a flexible cord, is
connected to the pivots 80 and 84. That flexible restraining
element limits the extent to which the torsion spring 76 can rotate
the U-shaped frames 40 and 54 away from each other; but that
flexible restraining element is long enough to enable those
U-shaped frames to subtend an angle of almost 90.degree.. A hook 90
has one end thereof rotatably mounted on the pivot 84, and has the
open end thereof dimensioned to telescope over the pivot 80. As
shown particularly by FIG. 5, that hook can coact with those pivots
to hold the U-shaped frames 40 and 54 in face-to-face
engagement.
The numeral 92 denotes a plate which has two ears, not shown,
adjacent one edge thereof. A pivot 94 extends through an opening in
one of those ears, through an opening in the ear 52 adjacent the
lower edge of the U-shaped frame 40, and through an opening in the
lower end of the flange 42 on that U-shaped frame to rotatably
secure one side of the plate 92 to that U-shaped frame. An opening
in the other ear on the plate 92 will receive a pivot, not shown,
which extends through an opening in the ear which is the
counterpart of the ear 52 and through an opening in the lower end
of the flange 44 on the U-shaped frame 40 to rotatably secure the
other side of that plate to that U-shaped frame. A torsion spring
96 surrounds the pivot 94 and bears against the U-shaped frame 40
and the plate 92; and that torsion spring urges that plate toward
the solid-line position shown by FIG. 3. However, that torsion
spring can yield to permit that plate to be rotated to the
dotted-line position in FIG. 3 and to the solid-line position in
FIG. 5.
The numeral 98 denotes a plate which can be identical to the plate
92; and it has ears 97 and 99 adjacent one edge thereof, as shown
by FIG. 4. A pivot 100 extends through an opening in the lower end
of the flange 56, through an opening in the ear 70 on the U-shaped
frame 54, and then through an opening in the ear 97 on the plate 98
to rotatably secure the left-hand side of that plate to that
U-shaped frame. A torsion spring 102 encircles the pivot 100 and
bears against the plate 98 and the U-shaped frame 54; and that
torsion spring urges that plate toward the solid-line position
shown by FIG. 3. However, that torsion spring can yield to permit
that plate to be rotated to the dotted-line position in FIG. 3 and
to the solid-line position in FIG. 5. A pivot 104 extends through
an opening in the flange 60, through an opening in the ear 72 on
the U-shaped frame 54, and through the ear 99 on the plate 98 to
rotatably secure the other side of that plate to that U-shaped
frame.
The protective pocket 26 of the bag-like receptacle 20 is
dimensioned to receive substantially all of the U-shaped frame 40
and all of the plate 92, and the protective pocket 30 of that
bag-like receptacle is dimensioned to receive substantially all of
the U-shaped frame 54 and all of the plate 98 -- as indicated by
dotted lines in FIG. 3. Further, the scoop 38 is small enough to be
held in the user's hand and to be completely enclosed by the
bag-like receptacle 20. When the plate 98 is in the solid-line
position shown by FIG. 3, and the U-shaped frames 40 and 54 have
not yet been moved toward each other to cause the protective
pockets 26 and 30 to engage droppings 106, the protective pocket 30
will assume the dotted-line position shown in FIG. 3. However,
after those U-shaped frames have been moved toward each other to
cause the protective pockets 26 and 30 to engage droppings 106, the
protective pocket 30 will assume a position comparable to the
dotted-line position shown in FIG. 3 for the protective pocket
26.
As the spaced-apart ends of the U-shaped frames 40 and 54 of the
scoop 38 are telescoped, respectively, into the protective pockets
26 and 30, the extension 58 at the end of the flange 56 on the
U-shaped frame 54 will be inserted in the perforations of the
perforated tabs 28 and 32, and the extension 46 at the end of the
flange 44 on the U-shaped frame 40 will be inserted in the
perforation of the perforated web 34. Those perforated tabs and
that perforated web will thereafter coact with those extensions to
prevent accidental separation of those protective pockets from that
scoop.
In using the scoop 38 and the bag-like receptacle 20 to pick up
droppings 106, the user will insert the thumb and fingers of one
hand into the protective pockets 26 and 30 and will grip the
handles 82 and 86. Thereupon, that user will urge the closed ends
of the protective pockets 26 and 30 into engagement with the ground
on opposite sides of the droppings 106, as indicated by FIG. 3. The
protective pockets 26 and 30 will isolate the plates 92 and 98 from
the ground and, more importantly, will isolate those plates from
the droppings 106. As the U-shaped frames 40 and 54 of the scoop 38
are moved close to the ground, the plates 92 and 98 will engage the
ground and be rotated from the solid-line positions to the
dotted-line positions of FIG. 3; and thus will assume positions
wherein they are immediately adjacent the ground and are close to
the plane of the lower surfaces of the droppings 106. At this time,
the user will force the handles 82 and 86 to move toward each
other, by using the thumb and fingers on his or her hand to apply
pressure to those handles and will thereby force the free ends of
the U-shaped frames 40 and 54 to move toward each other. As those
free ends approach each other, the confronting edges of the plates
92 and 98 will move into position beneath the droppings 106, and
will thereby lift those droppings off of the ground. Because the
plastic material of which the protective pockets 26 and 30 is made
has a slippery "feel," those protective pockets will enable the
plates 92 and 98 to slip under the droppings 106 with a minimum of
resistance.
When the portions of the protective pockets 26 and 30 are in
abutting relation, the user will lift the scoop 38, and hence the
protective pockets 26 and 30, upwardly and away from the ground;
and he will tilt those plates toward the vertical until the
droppings 106 fall downwardly into the portion of the bag-like
receptacle 20 which depends downwardly from the folded edge 22.
Those droppings will fall directly downwardly into the lower
portion of the bag-like receptacle 20, and they will come to rest
on the closed end of that bag-like receptacle. As the user raises
the scoop 38 and the bag-like receptacle 20, the restorative forces
within the torsion spring 102 will cause the plates 92 and 98 to
move toward positions wherein those plates coact with the generally
U-shaped frames 40 and 54 to generally subtend right angles.
However, as those restorative forces tend to move those plates to
those positions, the user will continue to urge the handles 82 and
86 toward each other; and hence the confronting ends of the plates
92 and 98 will continue to be immediately adjacent each other --
even though those confronting ends progressively move away from the
pivots 74 and 78. As those confronting ends of those plates
progressively move away from the pivots 74 and 78, they will move
the adjacent portions of the protective pockets 26 and 30 with
them, and hence the droppings will continue to be completely
enclosed. Hence, those droppings can be picked up and stored within
the bag-like receptacle 20 without any risk of their being released
accidentally.
Subsequently, the scoop 38 and the protective pockets 26 and 30 can
be moved back to the position of FIG. 3 and used to pick up any
further droppings in the area; and that scoop will permit those
droppings to fall downwardly into the closed end of the bag-like
receptacle 20. The one hand of the user will remain in engagement
with the handles 82 and 86, and thus will be displaced from the
plates 92 and 98 and from any droppings picked up by those plates.
Moreover, the inner surfaces of the protective pockets 26 and 30
will effectively interpose themselves between the user's hand and
any such droppings.
The plates 92 and 98 constitute laterally-offset free ends for the
U-shaped frames 40 and 54; and it will be understood that when the
confronting edges of those plates are immediately adjacent each
other, those plates will space other portions of those U-shaped
frames apart to define a space which is bounded by those plates and
by the inner faces of those U-shaped frames. That space is
important; because it provides a passage through the scoop 38 which
will enable the droppings 106 to fall downwardly into the closed
end of the bag-like receptacle 20 while the plates 92 and 98 are
adjacent each other, and thus will prevent escape of those
droppings. As a result, a user of the bag-like receptacle 20 and
scoop 38 of FIGS. 1-9 can pick up droppings 106 and transfer them
to the closed end of that bag-like receptacle without any need of
releasing his grip upon the handles 82 and 86, and without any need
of moving the confronting edges of the plates 92 and 98 apart.
As the scoop 38 is moved toward the position of FIG. 3, the closed
end of the bag-like receptacle 20 will respond to gravity and sag
down below the level of the folded edge 22. Consequently, any
droppings 106 within that closed end will not be able to fall out
of that bag-like receptacle and, instead, will remain in that
closed end. At the time the free ends of the plates 92 and 98
engage the ground, the portions of the bag-like receptacle 20 which
are intermediate the folded edge 22 and the closed end will be
essentially horizontal; and hence there will be no tendency of the
droppings within that bag-like receptacle to move toward, or
outwardly of, that folded edge. In this way, the present invention
makes it possible for the user of the scoop 38 and the bag-like
receptacle 20 to recurrently pick up and hold droppings without
accidentally releasing any of those droppings.
After all of the droppings in a given area have been picked up by
the scoop 38 and the protective pockets 26 and 30, and then
permitted to drop into the closed end of the bag-like receptacle
20, the perforated tabs 28 and 32 will be separated from the
extension 58 on the flange 56, and the perforated web 34 will be
separated from the extension 46 on the flange 44 of the scoop 38.
At such time, that scoop 38 can be withdrawn from the protective
pockets 26 and 30; and those protective pockets and the bag-like
receptacle 20 will then be supported by gripping the perforated
tabs 32 and 28. Thereupon, the free end 24 of the bag-like
receptacle 20 can be gripped and pulled upwardly above the upper
edges of the protective pockets 26 and 30. The user will grasp a
part of the free end 24 which has always been remote from those
parts of the protective pockets 26 and 30 which engaged the
droppings; and hence the user's hands will be spaced away from any
residue of those droppings which may have clung to those parts of
those protective pockets. Once the free end 24 of the bag-like
receptacle 20 has been raised upwardly beyond the upper edges of
the protective pockets 26 and 30, that free end can be tied in a
knot, as indicated by FIG. 1, to confine and enclose all of the
droppings therein, and also to confine and enclose the protective
pockets 26 and 30. Alternatively, that free end can be held closed
by a cord, rope or other fastener. During the use of the scoop 38
and of the protective pockets 26 and 30 to pick up droppings, the
major portion of the exterior of the length of the bag-like
receptacle 20 was folded back on itself and thus enclosed and
protected from all contact with the droppings. Subsequently, when
the free edge 24 was telescoped upwardly to enable the bag-like
receptacle 20 to confine and enclose the droppings and to confine
and enclose the protective pockets 26 and 30, the exterior of the
length of that bag-like receptacle was clean and was completely
devoid of any residue of the droppings. The knotted or tied
bag-like receptacle 20 can then be stored until it is picked up by
a trash hauler.
The center of gravity of the scoop 38 is located between the
handles 82 and 86 and the plates 92 and 98, and thus is located
close to the user's hand. This is desirable because it minimizes
the gravitation-induced rotational forces which the user's hand
must resist as that scoop and the bag-like receptacle 20 are used
to pick up droppings.
Referring particularly to FIGS. 10-14, the numeral 108 denotes a
bag-like receptacle which can be made of the same material of which
the bag-like receptacle 20 of FIGS. 1-9 is made. That bag-like
receptacle has a line 110 of perforations adjacent one end thereof;
and that line of perforations makes it possible to tear off the
adjacent portion 126 of that bag-like receptacle. The free end 114
of the bag-like receptacle 108 can be telescoped along the exterior
of that bag-like receptacle in a direction toward the closed end of
that bag-like receptacle; and, as that end is so telescoped, it
will create a folded, opening-defining edge 112 for that bag-like
receptacle. The free end 114 of the bag-like receptacle 108 will
preferably be telescoped almost all of the way toward the closed
end of that bag-like receptacle, as shown by FIG. 12.
The numeral 116 denotes a semi-rigid sleeve of cardboard,
polyethylene or other suitable material, which is dimensioned to
fit within the bag-like receptacle 108; and, initially, that
semi-rigid sleeve will be wholly enclosed by the bag-like
receptacle 108. That semi-rigid sleeve is normally flat, as shown
by solid lines in FIG. 11; but it can respond to the application of
inwardly-directed forces to the side edges thereof to assume the
tubular configuration shown by FIG. 13. The semi-rigid sleeve 116
has a line 118 of perforations adjacent the outer end thereof; and
that line of perforations makes it possible to free a pusher
element 122 which is made as a part of that semi-rigid sleeve.
Absorbent material 120 is secured to one end of one face of the
pusher element 122, as by a cement or the like. The portion of the
semi-rigid sleeve 116 which is disposed to the right of the line
118 of perforations in FIGS. 10 and 12 is secured in position
within, and is secured to the inner surface of, the bag-like
receptacle 108 by glue, cement or other means.
As shown by FIG. 10, the semi-rigid sleeve 116 is shorter than the
bag-like receptacle 108; but the right-hand end of that semi-rigid
sleeve will be held away from the closed end of that bag-like
receptacle by the glue, cement or other means. The free end 114 of
that bag-like receptacle can be telescoped along the exterior of
that bag-like receptacle toward the closed end of that bag-like
receptacle to expose the line 118 of perforations and the pusher
element 122 of that semi-rigid sleeve, as shown by FIG. 12. At such
time, that pusher element will be separated from the rest of the
semi-rigid sleeve 116, as by tearing that semi-rigid sleeve along
the line 118 of perforations. That tearing can be accomplished
while the major portion of the length of the semi-rigid sleeve 116
is disposed inwardly of the inverted-condition portion of the
bag-like receptacle 108, as shown by FIG. 12.
To pick up any droppings, the user will grip the inverted-condition
portion of the bag-like receptacle 108 with one hand and thereby
apply inwardly-directed forces to that position -- causing the
semi-rigid sleeve 116 to assume the tubular configuration indicated
by FIG. 13. With his other hand, the user will grip the pusher
element 122 and use it to move the droppings 124 into the
semi-rigid sleeve 116. The semi-rigid sleeve 116 will be relatively
stiff; and its outer end can be pressed against the ground in the
manner in which the edge of a dust pan is pressed against a floor
to facilitate the movement of debris into that dust pan.
After the droppings have been pushed into the semi-rigid sleeve
116, the user will tilt that outer end upwardly to enable gravity
to move those droppings toward the closed end of the bag-like
receptacle 108. Thereafter, the inner end of that semi-rigid sleeve
will resist any tendency of those droppings to move toward and
through the opening defined by the folded edge 112 of the bag-like
receptacle 108. Further, the tendency of the semi-rigid sleeve 116
to resume its generally-flat state will resist any tendency of the
droppings to move toward and through that opening. Additional
droppings can be introduced into the bag-like receptacle 108 by
placing the open end of the semi-rigid sleeve 116 adjacent those
droppings and by pushing those droppings into that open end by
appropriate manipulation of the pusher element 122.
As each dropping or group of droppings is introduced into the outer
end of the semi-rigid sleeve 116, that semi-rigid sleeve will have
its outer end tilted upwardly to cause that dropping or that group
of droppings to move toward the closed end of the bag-like
receptacle 108. The subsequent releasing of the inwardly-directed
forces, which caused that semi-rigid sleeve to assume the tubular
configuration of FIG. 13, will enable that semi-rigid sleeve to
start to resume the essentially-flat, solid-line configuration of
FIG. 11. If all of the droppings within the bag-like receptacle 108
are located between the inner end of the semi-rigid sleeve 116 and
the closed end of that bag-like receptacle, that semi-rigid sleeve
will essentially resume the solid-line configuration of FIG. 11,
and will thereby prevent accidental release of any of those
droppings. Even if some of the droppings are still within the inner
end of the semi-rigid sleeve 116, that semi-rigid sleeve will tend
to prevent accidental release of any of the droppings within the
bag-like receptacle 108, as by flattening itself as much as it can,
and by holding those droppings in position to block the escape of
further droppings. Consequently, the semi-rigid sleeve 116 will
effectively pprevent accidental release of any of the droppings
introduced into the bag-like receptacle 108.
After the various droppings have been introduced into the bag-like
receptacle 108, the absorbent material 120 on the pusher element
122 can be used to rub the surface on which the droppings were
found. That absorbent material will be wide enough, deep enough,
and absorbent enough to wipe away all or almost all traces of the
droppings. At such time, the semi-rigid sleeve 116 will have the
outer end thereof tilted upwardly, and it will be given the tubular
configuration of FIG. 13; and then the pusher element 122 can be
turned so its shortest dimension is in register with the open end
of the semi-rigid sleeve 116. Thereafter, that pusher element can
be released and thereby permitted to move down into that semi-rigid
sleeve, as indicated by FIG. 14. Releasing of the inwardly-directed
pressure on the side edges of the bag-like receptacle 108 will
enable the semi-rigid sleeve 116 to move into gripping engagement
with the pusher element 122. At this time, the free end 114 of the
bag-like receptacle 108 can be telescoped away from the closed end
of that bag-like receptacle until that bag-like receptacle assumes
the configuration indicated by FIG. 14; and, thereupon, that
bag-like receptacle will enclose and confine all of the droppings,
the semi-rigid sleeve 116, and the pusher element 122. In addition,
all areas of the inverted-condition portion of the bag-like
receptacle 108 which could have been contacted by any of the
droppings will be wholly at the interior of that bag-like
receptacle, and thus can not soil the hand of the user.
The portion 126 of the bag-like receptacle 108 can then be torn
away by applying tearing forces to the line 110 of perforations.
Once that portion has been torn away, it can be used as a tie to
close and secure the open end of the bag-like receptacle 108. That
open end could, if desired, be tied in a knot, as was the open end
of the bag-like receptacle 20 in FIG. 1. Alternatively, of course,
the open end of that bag-like receptacle could be closed and
secured by a length of cord, twine or the like.
Referring particularly to FIGS. 15-20, the numeral 130 generally
denotes a bag-like receptacle which has slots 132, 134 and 136
therein adjacent the open end thereof. As indicated particularly by
FIG. 15, the slots 132, 134 and 136 are generally rectangular, and
they have the long dimensions thereof extending circumferentially
of that bag-like receptacle. That bag-like receptacle will
preferably be made from a readily-flexible, tear-resistant,
dark-colored material such as polyethylene or polypropylene.
In using the bag-like receptacle 130, a portion of the open end
thereof will be inverted and telescoped along part of the exterior
of that bag-like receptacle to define a folded edge 138, as shown
particularly by FIGS. 16-18. The telescoping of that open end along
that part of the exterior of that bag-like receptacle also will
form pocket-like portions 140 and 142 between that part of the
exterior and the inverted-condition portion of the bag-like
receptacle; and those pocket-like portions are shown particularly
by FIGS. 16 and 17. As the open end of the bag-like receptacle 130
is inverted and telescoped along part of the exterior of that
bag-like receptacle, a short length 144 of that open end is folded
back on itself to form a reentrant edge. The closed end 146 of the
bag-like receptacle 130 will extend downwardly below the level of
the reentrant edge 144 of the bag-like receptacle 130, as shown
particularly by FIGS. 18-20.
The pocket-like portion 140 will accommodate the generally U-shaped
frame 54 and the plate 98 of the scoop 38, as shown particularly by
FIGS. 16 and 17. The pocket-like portion 142 will accommodate the
generally U-shaped frame 40 and the plate 92, as shown particularly
by FIGS. 16 and 17. The confronting edges of the plates 92 and 98
will engage portions of the inner surface of the folded edge 138 of
the bag-like receptacle 130; and the closed end 146 of that
bag-like receptacle will extend rearwardly toward the pivot 78 and
then pass downwardly between the confronting surfaces of the
generally U-shaped frames 40 and 54, as indicated particularly by
FIGS. 16, 18 and 20.
The slot 136 will be telescoped over the extension 58 of the flange
56 on the U-shaped frame 54, and the slots 132 and 134 will be
telescoped over the extension 46 on the flange 44 of the generally
U-shaped frame 40, as indicated particularly by FIG. 18. The
telescoping of those slots over those extensions will coact with
the restorative forces within the bag-like receptacle 130 to
prevent accidental separation of that receptacle from the scoop
38.
The user will insert the thumb and fingers of one hand through the
open end of the bag-like receptacle 130, and will grasp the handles
82 and 86 of the scoop 38, as indicated by FIG. 17. The torsion
spring 76 will bias the generally U-shaped frames 40 and 54 to the
spaced-apart positions indicated by FIGS. 16, 17 and 20, and thus
will tend to hold apart those portions of the folded edge 138 which
are adjacent the confronting ends of the plates 92 and 98, as
indicated by FIGS. 16, 17 and 20. The user will press those
portions of the folded edge 138 into engagement with the ground on
opposite sides of the droppings which are to be picked up, and then
will apply forces to the handles 82 and 86 which will cause the
plates 92 and 98 to move into essential parallelism with the ground
-- in the same manner in which those plates rotated from the
solid-line positions to the dotted-line positions of FIG. 3.
Thereafter, the user will apply inwardly-directed forces to the
handles 82 and 86 which will cause the portions of the folded edge
138 that envelop the confronting ends of the plates 92 and 98 to
move toward each other and thus in position beneath the
droppings.
At this time, the droppings will be completely surrounded by the
inner surface of the bag-like receptacle 130; and hence the user
can lift the scoop 38 and that bag-like receptacle without any fear
of permitting any of the droppings to escape. While still holding
the confronting ends of the plates 92 and 98 immediately adjacent
each other, the user will tilt the scoop 38 from a position
comparable to the position shown in FIG. 3 to a position comparable
to that shown by FIGS. 18-20. As the user raises and tilts that
scoop that the bag-like receptacle 130, the restorative forces
within the torsion spring 102 will cause the plates 92 and 98 to
move toward positions wherein those plates coact with the generally
U-shaped frames 40 and 54 to generally subtend right angles.
However, as those restorative forces tend to move those plates to
those positions, the user will continue to urge the handles 82 and
86 toward each other; and hence the confronting ends of the plates
92 and 98 will continue to be immediately adjacent each other --
even though those confronting ends progressively move away from the
pivots 74 and 78. As those confronting ends of those plates
progressively move away from the pivots 74 and 78, they will move
the adjacent portions of the folded edge 138 with them, and hence
the droppings will continue to be completely enclosed by the inner
surface of the bag-like receptacle 130.
As the user tilts the scoop 38 and the bag-like receptacle 130
toward the position shown by FIGS. 18-20, the droppings will
respond to gravitational force to move down into the closed end 146
of that bag-like receptacle, and thus will move out of register
with the plates 92 and 98 and also out of register with all
portions of the folded edge 138 of that bag-like receptacle. When
further droppings are to be picked up, the scoop 38 will again be
rotated and moved to dispose the confronting ends of the plates 92
and 98 thereof in general parallelism with the surface on which
those further droppings were deposited; but the
previously-collected droppings will remain within the closed end
146 of the bag-like receptacle 130. Specifically, the weight of
those previously-collected droppings will coact with the weight of
the closed end 146 of the bag-like receptacle to cause that closed
end to assume the dotted-line position shown in FIG. 18, wherein it
is below the level of the reentrant edge 144. That reentrant edge
will hold an adjacent portion 145 of the inner surface of the
bag-like receptacle against downward movement; and that adjacent
portion will serve as a barrier which will keep all
previously-collected droppings from being released from that
bag-like receptacle. Depending upon the length of the bag-like
receptacle 130, very substantial numbers of droppings can be
collected and held within the closed end 146 of that bag-like
receptacle without any of those droppings escaping through the
opening which is defined by the folded edge 138 of that bag-like
receptacle. Whenever the scoop 38 and the bag-like receptacle 130
are moved to the position of FIGS. 17-20, wherein the plates 92 and
98 are vertically-directed, the closed end 146 of the bag-like
receptacle 130 will assume the solid-line position of FIG. 18, and
thus will confine the droppings and will keep them from escaping
through the opening defined by the folded edge 138. When that coop
is moved to the position of FIG. 3, wherein the plates 92 and 98
are parallel to the ground, the closed end 146 of that bag-like
receptacle will droop below the level of the portion 145 of the
inner surface of that bag-like receptacle, as shown by dotted lines
in FIG. 18; and that portion will act as a barrier to those
droppings, and will keep them from escaping through the opening
defined by the folded edge 138. In this way, the bag-like
receptacle 130 can coact with the scoop 38 to pick up and hold a
large number of droppings without accidentally releasing any of
those droppings.
After the user has used the scoop 38 and the bag-like receptacle
130 to pick up all of the droppings in a given area, he will free
the slots 132 aand 134 from the extension 46 on the flange 44 of
the generally U-shaped frame 40. Thereupon, the weight of the
closed end 146 of the bag-like receptacle 130 and the weight of any
droppings within that closed end will cause that closed end to
swing downwardly and to the left in FIG. 18. Simultaneously, the
user can tilt the upper ends of the handles 82 and 86 forwardly and
downwardly to enable the intermediate and lower portions of the
bag-like receptacle to swing clear of the frames 40 and 54 of the
scoop 38. At this time, the bag-like receptacle 130 will be
supported by the engagement of the slot 136 with the extension 58
on the flange 56 of the U-shaped frame 54; and the user can
telescope the free end of that bag-like receptacle upwardly until
that bag-like receptacle assumes a configuration comparable to that
of the bag-like receptacle in FIG. 1. Alternatively, the user could
free the slot 136 from the extension 58 on the flange 56 of the
frame 54 and also free the slots 132 and 134 from the extension 46
on the flange 42 of the frame 40. That user could then apply forces
to the handles 82 and 86 of the scoop 38 which would force the
confronting ends of the plates 92 and 98 into holding engagement
with the adjacent portions of the folded edge 138 of the bag-like
receptacle 130. While continuing to apply those forces to those
handles, the user could telescope the free end of the bag-like
receptacle 130 off of the generally U-shaped frames 40 and 54 of
the scoop 38 until that bag-like receptacle assumed a configuration
comparable to that of the bag-like receptacle 20 in FIG. 1.
In either instance, because some areas of the exposed surface of
the inverted-condition portion of the bag-like receptacle 130 could
have some residue of droppings thereon, the user should insert his
hand within the pocket-like portions 140 and 142 to telescope the
free end of the bag-like receptacle 130 into the position indicated
by FIG. 1. In that way, the user could completely protect his hand
against any and all contact with the droppings or any residue
thereof. Where the user initially released the slots 132 and 134
from the extension 46 on the flange 42 of the frame 40, and then
supported the bag-like receptacle 130 by the engagement of the slot
136 with the extension 58 on the flange 56 of the frame 54, that
user could grip the upper portion of that bag-like receptacle and
lift the slot 136 away from the extension 58. In the alternative
instance, where the user freed the slot 136 from the extension 58
and also freed the slots 132 and 134 from the extension 46 and then
gripped the bag-like receptacle 130 with the plates 92 and 98, that
user could grip the upper portion of that bag-like receptacle and
then release the forces which he had been applying to the handles
82 and 86. Thereupon, the torsion spring 76 would move the plates
92 aand 98 away from tthe exterior of the bag-like receptacle 130,
and would thereby free that bag-like receptacle. In both instances,
all portions of the exterior of the bag-like receptacle 130 would
be clean and wholly free of residue of droppings; because all of
the portions of that bag-like receptacle which were permitted to
approach or touch any droppings would now be parts of the interior
of that bag-like receptacle. Consequently, the user could tie a
knot in the free end of that bag-like receptacle, or could use a
short length of string, twine or cord to tie that open end, and
could then set that bag-like receptacle aside for a trash
hauler.
Referring particularly to FIGS. 21-24, the numeral 150 generally
denotes a bag-like receptacle which preferably is made from a
sturdy, readily-flexible, tear-resistant, opaque plastic material
such as polyethylene or other film. Openings 152, 154, 156 and 158
are provided in the upper end of that bag-like receptacle; and, as
shown particularly by FIG. 21, those openings are spaced
circumferentially of the open end of that receptacle. Openings 160
and 162 are provided adjacent the closed end 165 of the bag-like
receptacle 150; and those openings are adjacent the opposite edges
of that closed end, as indicated particularly by FIG. 21. Those
openings will not permit anything to leak out of that bag-like
receptacle, because the front and rear surfaces of that bag-like
receptacle are sealed together adjacent those openings, as
indicated by the arcuate lines 163.
The numeral 164 generally denotes a scoop which has a frame 167 and
a frame 169; and the frame 167 has an L-shaped portion 166 with a
laterally-offset leading edge 176. Abutments 172 and 174 are
provided on the L-shaped portion 166; and those abutments incline
outwardly of the frame 167. That frame also includes rods or heavy
wires which connect the L-shaped portion 166 to a handle 178; and
those rods or heavy wires enable all portions of that frame to move
as a unit. The frame 169 has an L-shaped portion 180 with a
laterally-offset leading edge 190. Abutments 186 and 188 are
provided on the L-shaped portion 180; and those abutments incline
outwardly of the frame 180. That frame also includes rods or heavy
wires which connect the L-shaped portion 180 to a handle 192; and
those rods or heavy wires enable all portions of that frame to move
as a unit. Torsion springs 194 and 196 have the free ends thereof
secured to the handles 178 and 192; and those torsion springs urge
the frame 167 and 169, and the leading edges 176 and 190, away from
each other. However, those torsion springs can respond to
inwardly-directed forces on the handles 178 and 192 to permit the
frames 167 and 169 and the leading edges 176 and 190 to move toward
each other.
A hook 198 is secured to the rear end of the handle 178 in FIG. 22,
and a hook 200 is secured to the lower end of the handle 192. As
indicated particularly by FIG. 23, the rods or heavy wires of the
frames 167 and 169 have the axes thereof inclined relative to the
axes of the handles 178 and 192.
In using the bag-like receptacle 150, the user will telescope the
open end and part of the adjacent length of that bag-like
receptacle over the outer surface of the intermediate portion of
that bag-like receptacle, as indicated particularly by FIGS. 23 and
24. In doing so, that user will cause that bag-like receptacle to
develop an opening-defining folded edge 204 plus pocket-like
portions which are disposed between the intermediate portion of
that bag-like receptacle and the inverted-condition portion of that
bag-like receptacle. The user will insert the leading edges 176 and
190 into the pocket-like portions of the bag-like receptacle 150;
and those leading edges will be adjacent the inner surface of the
folded edge 204 of that bag-like receptacle. The opening 154 will
be hooked over the abutment 172, the opening 156 will be hooked
over the abutment 174, the opening 158 will be hooked over the
abutment 188, and the opening 152 will be hooked over the abutment
186. The hooking of these openings over those abutments will coact
with the restorative forces within the material of the open end of
the bag-like receptacle 150 to prevent accidental separation of
that bag-like receptacle from the scoop 164. The closed end 165 of
that bag-like receptacle will be passed successively through the
space defined by the leading edges 176 and 190, through the space
defined by the inner ends of the frames 167 and 169, and then
downwardly below the lower edges of those frames, as indicated by
FIG. 23. The opening 160 will be telescoped over the hook 198, and
the opening 162 will be telescoped over the hook 200; and the
engagements between those openings and those hooks will keep the
closed end 165 from drooping downwardly onto the surface on which
droppings are deposited.
To pick up any droppings, the leading edges 176 and 190 will be
placed on opposite sides of those droppings and in essential
parallelism with the surface on which those droppings were
deposited. Thereafter, the user will apply inwardly-directed forces
to the handles 178 and 192 which will force the portions of the
folded edge 204 of the bag-like receptacle 150, which are adjacent
the leading edges 176 and 190, to move toward each other and into
position beneath those droppings. At this time, those droppings
will be completely surrounded by the bag-like receptacle 150; and
hence the user can raise and rotate the scoop 164 and the bag-like
receptacle 150 to the position shown by FIG. 23. The droppings will
respond to gravity, during that raising and rotation, to move
downwardly into the closed end 165 of that bag-like receptacle. The
L-shaped configurations of the portions 166 and 180 will enable the
frames 167 and 169 to define a passage through the scoop 164 to the
closed end 165 of the bag-like receptacle 150 while the
laterally-offset leading edges 176 and 190 are in engagement with
each other. Consequently, those leading edges can effectively close
the opening defined by the folded edge 204 of that bag-like
receptacle, and thus prevent accidental release of any droppings,
while those droppings are caused to pass into the closed end 165 of
that bag-like receptacle.
When further droppings are to be picked up, the leading edges 176
and 190 will again be moved into essential parallelism with the
surface on which those further droppings were deposited. The
previously-picked up droppings will cause the closed end 165 of the
bag-like receptacle 150 to tilt and droop downwardly below the
level of the line defined by the abutments 174 and 188, as
indicated by dotted lines in FIG. 23. However, those abutments will
keep an adjacent portion 203 of the free end of the bag-like
receptacle 150, and hence an adjacent portion 205 of the interior
of that bag-like receptacle, from sagging down a corresponding
distance. Consequently, that portion of that interior will act as a
barrier between the closed end 165 and the opening which is defined
by the folded edge 204; and thus will prevent accidental release of
any of the previously-collected droppings. This enables the scoop
164 and the bag-like receptacle 150 to be used to pick up a very
substantial number of droppings without accidentally releasing any
previously picked up droppings.
As indicated by FIG. 23, the hooks 198 and 200 coact with the
openings 160 and 162 in the bag-like receptacle 150 to keep the
closed end 165 of that bag-like receptacle from sagging down onto
the surface on which the droppings were deposited; and, in doing
so, those hooks keep the closed end 165 from becoming soiled and
unclean. However, those hooks will coact with those openings to
permit the closed end 165 to sag downwardly below the level of the
line defined by the abutments 174 and 188, as indicated by dotted
lines in FIG. 23; and thus will enable the portion 205 of the
interior of the bag-like receptacle 150 to act as a barrier to
previously-collected droppings.
If desired, the closed end 165 of the bag-like receptacle 150 could
be passed through the space between the inner end of the L-shaped
portion 166 and the handle 178 of the frame 167, as indicated by
dotted lines in FIG. 24. Alternatively, that closed end could be
passed through the space defined by the inner end of the L-shaped
portion 180 and the handle 192 of the frame 169. In either of these
events, the openings 160 and 162 will not be telescoped over the
hooks 198 and 200 and, instead, will permit the closed end 165 to
assume the position shown by dotted lines in FIG. 24. Droppings can
be picked up by disposing the leading edges 176 and 190 of the
L-shaped portions 166 and 180 immediately adjacent a surface at
opposite sides of those droppings, and then moving those leading
edges into position beneath those droppings. Subsequent raising and
tilting of the scoop 164 and the bag-like receptacle 150 into a
position wherein the axes of the handles 178 and 192 are horizontal
and wherein the closed end 165 of the bag-like receptacle 150
droops downwardly at right angles from the L-shaped portion 166
will permit the droppings to move downwardly past the L-shaped
portion and into that closed end. Thereafter, when the leading
edges 176 and 190 of the scoop 164 are moved adjacent a further
surface on which further droppings were deposited, the
previously-collected droppings will not be able to escape from the
closed end 165 of the bag-like receptacle 150; because that closed
end will sag downwardly to the dotted-line position of FIG. 24, and
the portion of that bag-like receptacle which is adjacent the inner
end of the L-shaped element 166 will act as a barrier to the escape
of the previously-collected droppings.
After all of the droppings have been picked up and collected, the
user can free the openings 160 and 162 from the hooks 198 and 200,
respectively, and also can free the openings 156 and 158 from the
abutments 174 and 188, respectively. Thereupon, the weight of the
closed end 165 of the bag-like receptacle 150 and the weight of any
droppings within that closed end will cause that closed end to
swing downwardly and to the left in FIG. 23. Simultaneously, the
user can tilt the upper ends of the handles 178 and 192 forwardly
and ownwardly to enable the intermediate and lower portions of the
bag-like receptacle 150 to swing clear of the frames 167 and 169 of
the scoop 164. At this time, the bag-like receptacle 150 will be
supported by the engagement of the openings 152 and 154 with the
abutments 186 and 172, respectively; and the user can telescope the
free end of that bag-like receptacle upwardly until that bag-like
receptacle assumes a configuration comparable to that of the
bag-like receptacle in FIG. 1. Alternatively, the user could apply
inwardly-directed forces to the handles 178 and 192 which would
cause the leading edges 176 and 190 of the frames 167 and 169 to
move toward each other and grip and hold adjacent portions of the
folded edge 204 of the bag-like receptacle 150. The openings 152,
154, 156 and 158 of the bag-like receptacle 150 would be released,
respectively, from the abutments 186, 172, 174 and 188; and, if the
openings 160 and 162 had been telescoped over the hooks 198 and
200, respectively, those openings would be freed from those hooks.
Thereafter, the open end of the bag-like receptacle 150 would be
telescoped off of the frames 167 and 169 of the scoop 164 until the
bag-like receptacle 150 had a configuration similar to that of the
bag-like receptacle 20 in FIG. 1. In either instance, all portions
of the bag-like receptacle 150 which could have touched any
droppings, or any surface on which those droppings were deposited,
will be at the inner surface of that bag-like receptacle; and hence
the entire exterior of that bag-like receptacle will be clean and
unsoiled. The open end of that bag-like receptacle can then be tied
in a knot or can be suitably held closed by a short length of cord,
twine or the like. In this way, the scoop 164 and the bag-like
receptacle 150 can be used to collect droppings without exposing
the user to any contact with those droppings or any residues
therefrom.
The L-shaped portions 166 and 180 are shown as being made from
plastic material, as by an injection molding process; and, further,
those L-shaped portions are shown as being imperforate. However, if
desired, those L-shaped portions could be made from rods or heavy
wires; and, in that event, those L-shaped portions would have large
openings therein. Those openings would be useful in reducing the
overall weight of the scoop 164. In the event the L-shaped portions
166 and 180 were to be made from rods or heavy wires, they could be
made integral with the rods or heavy wires of FIGS. 22-24 which
connect those L-shaped portions to the handles 178 and 192. In such
event, the abutments 172, 174, 186 and 188 could be formed on those
rods or heavy wires, or could be formed on cross tie rods which
could occupy positions corresponding to the positions occupied by
the inner ends of the L-shaped portions 166 and 180.
The extensions 46 and 58 of the scoop 38 of FIGS. 3-5 are useful in
holding the tabs and webs of the bag-like receptacle 20 and in
holding the tabs and webs of the bag-like receptacle 130.
Similarly, the abutments 172, 174, 186 and 188 and the hooks 198
and 200 of the scoop 164 of FIGS. 22-24 are useful in holding the
bag-like receptacle 150. However, if desired, any one or more of
those extensions, abutments or hooks could be replaced by another
fastener; and, where that fastener was a spring-type clip, the
corresponding perforation, slot or opening in the bag-like
receptacle could be eliminated. Hence, it should be clear that
unperforated bag-like receptacles could be used with the scoop 38
or the scoop 164 if those scoops were equipped with fasteners which
did not require perforations, slots or openings. Further it should
be understood that a user need not fit each of the openings 152,
154, 156 and 158 of the bag-like receptacle 150 over an abutment on
the scoop 164 and that he need not fit both of the openings 160 and
162 in that bag-like receptacle over the hooks 198 and 200 on that
scoop. All that is needed is that sufficient openings be fitted
over the holding surface therefor to prevent accidental separation
of that bag-like receptacle from that scoop, to keep the closed end
165 of that bag-like receptacle from drooping down onto the ground,
and to enable the portion 205 of the interior surface of that
bag-like receptacle to act as a barrier to previously-collected
droppings. In addition, it should be noted that the abutments 172
and 174, which are angularly displaced to enable both of them to be
shown in FIG. 24, will preferably be co-planar. Similarly, it
should be noted that the abutments 186 and 188 will preferably be
co-planar.
If desired, the sleeve 116 of FIGS. 10-14 could be merely
telescoped into, rather than secured within, the bag-like
receptacle 108. In such event, that sleeve could be removed from
that bag-like receptacle, could be forced to assume the tubular
configuration of FIG. 13, and could then have the
longitudinally-folded or pleated closed end of that bag-like
receptacle telescoped into the left-hand end thereof. If just one
dropping were to be picked up, that closed end could be unfolded or
smoothed out and left wholly within that sleeve. However, if
several droppings were to be picked up, the closed end of that
receptacle would be passed all the way through that sleeve and
disposed outwardly of the opposite end of that sleeve and then
unfolded or smoothed out. Thereafter, the free end 114 of that
bag-like receptacle would be folded back along the outer surface of
the sleeve 116 toward the closed end of that bag-like receptacle;
and, at that time, the left-hand end of that sleeve would be
adjacent the folded edge 112, and would be enclosed within the
pocket-like portion defined by the inverted-condition portion and
the portion telescoped through that sleeve. After the sleeve 116
and the bag-like receptacle 108 had performed their function of
picking up the dropping or droppings, the inverted-condition
portion of that bag-like receptacle would be telescoped off of that
sleeve and suitably held closed, as indicated by FIG. 14.
Whereas the drawing and accompanying description have shown and
described several preferred embodiments of the present invention,
it should be apparent to those skilled in the art that various
changes can be made in the form of the invention without affecting
the scope thereof.
