Multiple compartment refuse container
Abstract
A multiple compartment refuse container is provided wherein the
compartments have doors both at the top and at the sides of the
compartment structure. The refuse container may be used with
plastic bags which are easily fastened inside of the container or
it may be used with conventional garbage cans. The user of the
container merely lifts the top and drops refuse therein and the
container is easily emptied by means of side doors. The container
is ordinarily built in two or four compartment models but any
number of compartments may be employed.

Claims
I claim:
1. In an above-ground container for refuse and the like comprising
a rectangular box-like structure divided into a plurality of
compartments by partitions, each of said compartments being
provided with a top surface with an opening for inserting refuse
and an upstanding rim surrounding said opening, a top raising
hinged door with a downward depending flange along each edge, said
door normally held in a closed position solely by gravity to cover
said opening and said rim, and a handle retractable by gravity, and
a side door whereby a receptacle within the container can be filled
through the top door and the contents removed through the side
door, the improvement comprising a second rim closely surrounding
all sides of the top door, said rim rising from said top surface to
a height approximately equal that of the top surface of the door
whereby an animal or the like cannot get its claws under said
handle or the edges of said door to raise the door.
Description
SUMMARY OF THE INVENTION
In the past, trash containers in public parks or the like have
ordinarily been constructed under ground and it is difficult to
empty such containers and to keep them clean. The container of the
present invention has been specifically developed for use by the
United States Forest Service but it may be used in public
campgrounds, parks or the like in any situation wherein it is
desired to provide an unobtrusive, easily maintained refuse
container.
The present invention provides a centralized container service for
trash and the like, reducing the cost of trash pickup.
In accordance with one embodiment of the invention a rolled edge on
the lid makes it possible to suspend plastic trash bags within the
container without the use of metal clips or the like.
The container has top doors each of which has a limiting device
thereon so it is impossible for the user to leave the container in
an open position.
The container of the present invention has side doors thereon so
that it is easy to remove the contents of the container without the
necessity of lifting the contents through the top opening.
The collection costs when utilizing the containers of the present
invention have proved to be only 1/2 to 3/4ths of that of existing
underground units previously used by the United States Forest
Service.
The containers of the present invention are rugged and esthetically
pleasing.
In accordance with one embodiment of the invention, skids are
provided under the container together with eye bolts for towing so
that it is easy to move the containers to a desired location.
Various additional features and advantages of the present invention
will be brought out in the balance of the specification.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view of a four compartment container
embodying the present invention.
FIG. 2 is a plan view of the device shown in FIG. 1, with certain
of the parts in section.
FIG. 3 is a front elevation of the structure shown in FIG. 1, with
certain of the parts in section.
FIG. 4 is a section on the line 4--4 of FIG. 3.
FIG. 5 is an enlarged detail of a bolt fastener used to fasten the
doors closed.
FIG. 6 is a section on the line 6--6 of FIG. 3.
FIG. 7 is an enlarged detail on the line 7--7 of FIG. 3.
FIG. 8 is a partial perspective top view of one of the containers
showing the use of the clips to hold plastic garbage bags in
position.
FIG. 9 is a view similar to FIG. 8 showing the use of corner loops
for holding a garbage bag.
FIG. 10 is an enlarged section on the line 10--10 of FIG. 9.
FIG. 11 is a perspective view of another embodiment of the
invention wherein the top is hinged at the rear of the structure
and wherein a two-unit container is provided. The drawing also
shows the use of the container with a conventional garbage can
rather than with a plastic trash bag.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings by reference characters, the refuse
container of the present invention includes a rectangular box-like
structure generally designated 11, having ends 12 and 14, a back
member 16 and a top member 18. Dividers 20 serve to stiffen the
structure and to divide the container into a plurality of
compartments. A bottom 21 serves to complete the basic
structure.
The top 18 is provided with a series of openings each of which is
provided with a lid 22 hinged as at 24 and having a lip 23. In the
model shown in FIGS. 1 through 3, the lids are hinged at one side
although as will be later apparent, the lids may be hinged at the
rear of the structure. A restraining member 26 such as a wire or
rod is provided which permits the lids to be opened to less than
90.degree., so that the lids are self closing by gravity and the
user cannot leave the container open.
At the front of the compartment doors 28 and 30 are provided which
are substantially the full width of each compartment. One of the
doors is provided with a lip 32 which lies over the opposite door
and has a sliding bolt 34 so that each pair of doors can be closed
and fastened securely.
A raised rim 36 is provided around each of the top openings and
this serves both as a means of hanging a plastic garbage bag inside
the container and also tends to form a seal with the overhanging
lip 23 of lid 22.
Each of the lids is provided with a retractable handle 38 which can
be easily grasped but which will fall flush with the top of the lid
by gravity when released, making it difficult for animals to pry
open the lid. In many parts of the country, bears are a nuisance
around refuse containers in which case a rim 40 is provided
surrounding the lids so that bears or other animals cannot get
their claws under the lid and raise it.
In normal use a plastic bag is fastened to the upstanding rim 36.
This can be accomplished in one of two ways as is shown in FIGS. 8
and 9. In the embodiment shown in FIG. 9 a series of U-shaped clips
42 are provided and the plastic bag is merely draped over the
upstanding rim 36 and the clips placed over the edges of the bag
opening to hold the bag firmly in place. In accordance with the
embodiment of the invention shown in FIG. 9 the clips are
eliminated and sections of half round rod 44 have been welded or
otherwise fastened to the corners of rim 36. As is shown in FIG.
10, plastic bag 46 is placed in the opening formed by the rim 36
and the ends of the corners of the bags tucked under the rod 44 as
is shown at 48.
Preferably the container is provided with skids 41 and towing
eyebolts 43, so that the entire container can be easily moved from
place to place.
In FIG. 11 another embodiment of the invention is shown wherein the
container, generally designated 50, is divided into two
compartments. In this embodiment the lids 52 are hinged at 54 on
the back of the compartment rather than at the side as previously
described. Also there is illustrated in this drawing the use of an
ordinary garbage can 56 instead of the plastic bags previously
shown. Obviously the rear hinging arrangement can be used with the
four compartment container and also the two compartment container
could have the lids hinged at the side rather than at the back.
Otherwise the structures are the same. Also, it will be noted that
in FIG. 11 the rim 40 is not employed since in many instances where
bears or other large animals are not a nusiance, this protective
edge is unnecessary.
Various variations of the exact structure shown may be made without
department from the spirit of this invention. The refuse container
can be made of any suitable material but is preferably fabricated
from steel sheets.
