is of a size to fit completely within the area of said triangular
base panel.
Description
BACKGROUND OF THE INVENTION
This invention relates to a combination scoop and self-sealing
container, particularly adapted for use by pet owners in removing
solid wastes from public walkways and the like.
The problem of removal and disposal of solid wastes from animals
along public streets and walkways is certainly not a new one. In
the past, these problems have been considered primarily problems of
the city or municipality itself, and of the pedestrian who should
watch where he is going.
Several factors are operating to change this picture today. First
of all, our cities and metropolitan areas are becoming more and
more crowded. This coupled with the national concern over the
environment and ecology has caused a rising concern over the
problem.
In certain densely populated metropolitan areas, such as for
example, New York City, it is now the pet owner himself who must
remove his pet's solid waste from public walkways.
Bearing these considerations in mind, it is an object of this
invention to provide a basic design for enabling a pet owner to
remove solid wastes conveniently from public walkways and convey it
in a sanitary fashion to an appropriate receptacle or
depository.
It is a further object of this invention to provide an easily
sealed, generally odor-proof, leak-proof scoop for the purposes
described.
It is a further object of this invention to provide a device of the
character described which may be easily and inexpensively
manufactured.
Still another object of the invention is to provide a closeable,
disposable, paperboard scoop which may be shipped and stored in the
flat condition, and readily erected into condition for use.
Still another object of the invention is to provide a paperboard
blank for producing a closeable, disposable scoop which includes a
detachable pusher.
SUMMARY OF THE INVENTION
Broadly considered, this invention contemplates a paperboard blank
having a central, equilateral triangle. Isosceles triangles are
joined by score lines to the three edges of the base triangle. A
single fold line is provided from the apex of the base triangle to
the apex of one of the attached isosceles triangles, so that the
blank may be folded along this line and the edges of the two
remaining isosceles triangles joined as by glue tabs or the like to
form a handle. In this condition, the scoop is flat folded for
storage, shipping, and the like.
Upon erection, the blank of this invention will form a four-sided,
pyramidal shaped scoop, with a triangular panel foldable from an
open position so that the scoop may receive its contents to a
closed and substantially sealed position.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view of the scoop of this invention as
erected and open for use.
FIG. 2 is a perspective view of the scoop of this invention as
closed.
FIG. 3 is a plan view of a paperboard blank according to this
invention.
FIG. 4 is a view showing the blank of FIG. 3 as folded and glued
for shipment or storage.
DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring first of FIG. 3, a completed paperboard blank is shown in
the flat condition. It will be observed that it includes a central
equilateral triangle 10, and the isosceles triangles 12, 14, and 16
joined to its side edges along the scorelines 18, 20, and 22,
respectively.
The outer side edges of the isosceles triangle 14 are provided with
the handle member 24 and the tab 26 along the fold lines 14a and
14b, respectively. Similarly, the free edges of the isosceles
triangle 16 are provided with the handle member 28 and the tab 30
along the fold lines 16a and 16b, respectively.
The pusher 32 may be disposed adjacent one edge of the isosceles
triangle 12. Preferably, a line of perforations 34 will be provided
so that when ready for use, the pusher may be readily detached.
The free edge 36 of the isosceles triangle 12 may be provided with
the closure tab 38. As will be explained presently, the ends of tab
38 are adapted to be engaged in the slots 40 formed in the
isosceles triangle panel 14.
After the blank is cut and scored as shown and described above, it
will be folded once along the score line 42 extending from the apex
of the base triangle panel 10 to the apex of the isosceles triangle
panel 12. This will bring the blank to the position shown in FIG.
4. The handle members 24 and 28 are in juxtaposition and they may
be secured together in any suitable manner such as by adhesive,
staples, or the like. In this condition, a scoop of this invention
is ready for shipment and storage. Indeed, it may be carried in
this condition by the pet owner until its use is required.
To erect the folded blank to a condition for use, the triangle
panel 10 is brought back to the flat condition, which of course
requires folding of the container along the scorelines 20 and 22,
and along the lines 14a and 16a. The triangular panel 12 is then
folded downwardly along the scoreline 18 to a position under the
triangular panel 10.
This is the condition of the erected scoop as shown in perspective
in FIG. 1. Of course, the pusher 32 has been detached from the
triangular panel 12. It will be observed that the handle members 24
and 28 extend upwardly from the scoop to facilitate handling by the
pet owner. The scoop is grasped by the upstanding handle members
and placed with the scoreline at the open edge of triangular panel
10 against the ground. Solid wastes or the like may then be pushed
into the container with the help of the pusher 32. The solid wastes
and the pusher 32 are then sealed within the container by folding
the panel 12 upwardly along the line 18, bringing it to bear
against the inwardly folded flaps 26 and 30. It may be locked in
the closed position by means of the closure tabs 38 and slots 40
described earlier.
It will be apparent to the skilled worker in the art that many
modifications may be made without departing from the scope and
spirit of this invention. For example, adhesive may be applied to
the tabs 26 and 30 to eliminate the closure flap 38.
Preferably, this invention contemplates that the blank be formed of
a waterproofed, semi-rigid paperboard. It will of course be
apparent to the skilled worker in the art that a variety of other
materials may be utilized.
Accordingly, no limitations are to be inferred or implied except
insofar as specifically set forth in the claims which follow.
