PORTABLE SANITARY PUTRESCIBLE MATERIAL COLLECTOR ASSEMBLY
Abstract
A receptacle is pivoted to a handle so that it may assume both a
horizontal position for accepting putrescible material from the
surface on which it is lying, and a vertical position for compact
storage and when removing the putrescible material. The handle is
hollow and serves as a storage area for a sweepstick when the
sweepstick is not in use. The handle bottom forms a tight fitting
cover for the receptacle when vertical. Both the working end of the
sweepstick and the interior of the receptacle are equipped with
disposable sanitary coverings.

Claims
What is claimed is:
1. A portable sanitary putrescible material collector assembly
comprising:
a. a handle;
b. a receptacle pivotally mounted thereto and having an open
end;
c. a sweepstick for use in pushing articles into said receptacle,
retained by said handle;
d. a liner detachably disposed within said receptacle and extending
beyond the open end of said receptacle and about the outer portion
of said receptacle forming said open end; and
e. a cover attached to said handle to engage said liner along that
portion thereof which extends about said open end of said
receptacle.
Description
BACKGROUND OF THE INVENTION
This invention relates to portable janitorial-type small waste
collection devices, and more particularly, to those used to collect
the inconveniently disposed fecal droppings of pets.
Devices somewhat similar to the present invention are known, for
example, for use in public places to remove cigarette butts and
small pieces of paper from the floors. However, these devices are
basically unsanitary and generally do not comprise an assembly;
being merely a shovel and separate brush. For the domestic animal
lover, these devices are not only unsanitary, but, in a very
practical way, unsatisfactory, particularly for use when "walking"
a dog or similar pet.
SUMMARY OF THE INVENTION
The disadvantages of prior art devices have been corrected in the
present invention. The present device is easy to use. A pet owner
need not strain his back or stoop to the floor or sidewalk to
collect the putrescible material, since both the receptacle and the
sweeping means are at the end of long handles, thereby enabling the
putrescible material to be collected while the user remains
upright. The present device is easy to store, since the sweeping
means are stored in the handle of the receptacle when the device is
not in use, and the pivoted receptacle permits upright storage in a
minimum of space. The present device is sanitary, since a
disposable sanitary covering surrounds the working end of the
sweepstick, and a disposable sanitary bag conforming to the
interior of the receptacle is placed within and extends around the
exterior lip or margin of the receptacle.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view of the assembly standing upright with
a portion shown in phantom; and
FIG. 2 is a right side view partially in section and foreshortened
of the device shown in FIG. 1; shown in alternate position on an
environmental surface shown in phantom lines.
DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to the figures, a handle 10, waist-high and cylindrical
in shape, is attached to a cover 11. Yoke members 13 of receptacle
cover 11 are pivoted to receptacle 12 with pivot pins 14. A hollow
space 15 inside the handle 10 serves as a storage space for a
sweepstick 16. Sweepstick 16 at its working end 17 tapers to a
wedge-shaped edge 20, broadest at its free end, which is covered by
a disposable sanitary covering 18. In the preferred embodiment the
covering 18 is a plastic bag or the like which can be disposed over
the wedge-shaped edge 20 by inserting the edge into the large
opening in a bag and which can thereafter be drawn inwardly about
the sweepstick 16 and retained in any suitable fashion, as by means
of a rubber band, twister or the like, so that the bag does not
inadvertently come off and expose the working end 17. In this
manner the assembly can be carried from place to place in a
sanitary condition. The interior of the receptacle 12 is lined with
a disposable sanitary bag 19, made of any suitable material, such
as plastic or paper. The bag is constructed and arranged such that
it is folded back upon itself about the outer margin 21 of the
opening in the receptacle 12. With the bag so positioned, as shown
in FIG. 2, it can be placed against an environmental surface, such
as shown in phantom lines designated generally 23 and representing,
for example, a sidewalk, for receiving material being swept from
the surface into the bag or container.
Referring to FIG. 2, the operation of this assembly can be readily
understood. A dog owner, for example, walking his dog along the
city sidewalk, can easily carry the entire assembly in one hand.
Once the dog defecates, the owner places the receptacle on its base
24 on the sidewalk and then pivots it forwardly about the lead edge
26 so that its front surface 28 assumes the position shown in FIG.
2 wherein the portion of the bag 19 disposed about the outer
surface of the receptacle 12 is sandwiched between the surface 28
and the sidewalk. He then removes the sweepstick 16 and the
covering 18, and uses the working end of the sweepstick to sweep or
push the fecal droppings of his pet into the bag 19. Having done
so, he merely lifts the handle 10 of the device and, if necessary,
guides the receptacle 12 as it rotates to the vertical position
shown in FIG. 1. The sweepstick 16 can then be placed back in the
hollow handle 10, and the covering 18 disposed about the working
end so as to provide a sanitary assembly once again.
The fecal material is now held in a sanitary condition in a closed
container by virtue of the clamping effect provided by the jaw-like
action of the receptacle cover 11 and receptacle 12 clamping the
bag 19 therebetween as shown in FIG. 1. Upon reaching a trash
container, the dog owner can dispose of the bag by merely inserting
his fingers between the outer surface of receptacle 12 and the
portion of the bag which is wrapped about that outer surface, and
lifting the bag, which can then be thrown into the trash container
or tied closed and then thrown into the trash container.
Alternatively, the owner can use the working end of the sweepstick
16 to remove the bag and dispose of it in the trash container.
Cover 11 and receptacle 12 form a closed container whenever
receptacle 12 is in an upright position, as when carrying away
putrescible material or when being stored. This feature is highly
desirable since it minimizes spreading noxious odors about the
home. Sweepstick 16 being stored inside handle 10 eliminates the
problem of the two becoming separated inadvertently. Since the only
parts that come into actual contact with the putrescible material
are covered with sanitary coverings that are disposed of after each
use, cleaning the assembly after each use is not required. Since
the assembly is relatively simple in nature, it is envisioned that
it possibly could be produced entirely from a plastic or other
inexpensive material.
Although a specific form of the invention has been selected for

specific terms for the purpose of describing this form of the
invention, this description is not intended to limit the scope of

It will be understood that various changes in the details,
materials and arrangement of parts which have been described and
illustrated above in order to explain the nature of this invention,
may be made by those skilled in the art within the principle and
scope of the invention as described in the appended claims.

set forth above is intended to provide a non-legal technical
statement of the contents of the disclosure in compliance with the
Rules of Practice of the U.S. Patent Office, and is not intended to
limit the scope of the invention as claimed herein.
