Abstract
A container for the collection of waste products including a base receptacle and a cover, the base receptacle having an upper lip portion, at least one rim portion and a supporting ledge. The cover is removably engageable with the base receptacle such that at least a portion of the cover engages at least a portion of the at least one rim portion when the cover is installed on the base receptacle thereby providing at least one peripheral area of contact between the cover and the base receptacle for securing a flexible bag liner therebetween. The base receptacle and cover are molded together as a one piece integral unit joined together by a web of material which connects the two component parts together. The cover is separated from the base receptacle by removal of the web of material.
Description
BACKGROUND OF INVENTION
This invention relates generally to containers for the collection of waste products and, more particularly, to a method and several embodiments of a waste container adaptable for use as a recycling container having a base receptacle and a removable cover positionable thereon, the installation of the cover member on the base receptacle providing at least one peripheral area of contact between the cover and the base receptacle for securing a flexible bag liner therebetween when installed.
Numerous refuse or waste containers are known in the industry and take many different forms involving many types of structures. Although many of these containers are adequate for their purpose, they have certain shortcomings particularly when used for specialized purposes such as for collecting and storing recyclable goods.
One type of waste or refuse container is an open top, uncovered receptacle that can have removably suspended therein a bag type liner which can be removed by refuse collection crews for transport to a landfill or a recycling site. However, often times, it is difficult to remove the liner from the container or, more frequently, the liner becomes dislodged from its mounting position around the upper lip of the container preventing collection of some refuse in the liner thereby requiring extra time by the crew to gather and recollect the waste. By having an open, uncovered top, the interior of the receptacle is exposed to weather elements such as rain and wind and if tipped over, the collected waste will spill requiring additional time by the collection crew to clean up. Further, because of the open top, a wide variety of different types of waste products and recyclable containers can be disposed of in the receptacle making recycling more difficult.
Waste receptacles are also provided with covers that are selectively removable. Such covers can take one of two basic forms. In one form, the cover itself is removed to provide access to the interior of the receptacle for the disposal of waste. For public use, the removal of a cover in order to dispose of waste is an inconvenience and therefore many people will not dispose of waste products in the receptacle but rather leave it as litter requiring clean up crews to gather and dispose of such waste. The second form of cover typically has a hinged door or the like associated therewith to selectively provide access to the interior of the receptacle. The use of hinged doors allows access into the interior of the container to both deposit and remove selected refuse and to visually see inside the interior of the receptacle. Hinged doors are generally rectangular in shape and they utilize one straight edge portion of the door for an elongate hinge and closure device (e.g., a spring) allowing for a wide variety of waste to be deposited in the receptacle. This type of cover is more convenient for the public but such doors are susceptible to wear, tear and breakage. They also sometimes become stuck in the open position exposing the interior of the receptacle to the elements. Still further, since such doors are not shape specific to any particular recyclable containers, a wide variety of waste can be deposited through such doors making it difficult at a recycling facility to separate recyclable material from non-recyclable material.
Covers may also be attached to the base receptacle. One form of attachment is by hingedly mounting the entire cover unit to the base. However, this typically leaves an exposed hinge and can negatively affect the aesthetics of the overall container. Further, the use of hinges requires that there be at least one generally straight side or edge to accommodate the hinge thereby limiting the potential number of available shapes and designs for the overall refuse container.
There is thus a need for an improved waste collection container particularly for the collection of recyclable material. Accordingly, the present invention is directed to overcoming one or more of the problems as set forth above.
SUMMARY OF THE INVENTION
The present invention relates to a refuse or waste container adapted particularly for the collection of recyclable materials. The refuse container includes a base receptacle having an upwardly opening mouth portion over which a portion of a flexible bag liner may be secured. A removable cover is provided for engagement with the base receptacle, the cover having an access port or opening selectively substantially sealed by a door. The mouth portion of the receptacle may include a plurality of differently sized perimeters to ensure a snug fit between the liner and the base receptacle. The cover may engage the liner in one or more longitudinally separated positions to help retain the liner in proper position within the base receptacle.
The cover and base receptacle may also be connected together by a flexible link member which is contained completely within the interior of the cover and base receptacle. The flexible link member can be positioned to help separate a flexible disposable liner from the base receptacle. A display panel may also be removably mounted to the exterior of the container such that it can be easily changed and/or replaced allowing for advertising indicia and other promotional information to be displayed on the container.
The present invention also relates to a method of making a waste container. The container is molded of a polymeric material as a one piece unit facilitating its manufacture by molding techniques such as blow molding or rotational molding. The cover portion and the base receptacle portion of the container are connected together during the molding process by a web of material that is formed integral with and extends between the cover portion and the receptacle portion. The cover and receptacle portions are then separated by removal of the web. Since both portions are molded simultaneously, the shrinkage (an inherent aspect of molding) after molding is substantially the same and predictable thereby simplifying the container manufacturing process and ensuring a compatible fit between the lower portion of the cover and the upper portion of the base receptacle.
These and other aspects and advantages of the present invention will become apparent upon reading the detailed description in connection with the drawings and the appended claims.

DETAILED DESCRIPTION
Referring to the drawings more particularly by referenced members wherein like numerals throughout the various drawings refer to like parts, as best illustrated in
FIGS. 1 and 3
, the reference numeral
1
designates generally a refuse or waste container that includes a cover
3
and a base receptacle
5
. A flexible bag liner
7
(
FIG. 4
) may be inserted into the receptacle for the collection, storage and removal of waste (not shown). A flexible link member
9
(
FIGS. 3 and 6
) may likewise be secured to both the cover
3
and receptacle
5
connecting the same together to prevent loss when the cover
3
is removed from the receptacle
5
. An optional weight
11
may be provided in the receptacle
5
to help prevent tip-over of the overall container
1
. The weight
11
is shown in dotted outline form in FIG.
3
and rests in the lower interior portion of the receptacle
5
. The container
1
can be of any suitable shape such as that of a beverage bottle as illustrated.
The cover
3
, as best seen in
FIGS. 1 and 3
, includes a top portion designated
13
and a side wall portion
15
depending from the top
13
. The cover
3
has a hollow interior
16
to provide for both lightness in weight and a pathway for the passage of refuse to the receptacle
5
that is placed through a port or passageway
17
in the side wall
15
. The passageway
17
communicates with a hollow interior
19
in the receptacle
5
. The lower end portion
20
of the cover
3
defines an open mouth or receiving area
21
for receipt of an upper portion
22
of the receptacle
5
therein. Alternately, the lower end
20
of the cover
3
may be received inside of the upper end
22
of the receptacle
5
to form the overall container
1
. The lower end portion
20
of cover
3
is preferably tapered or otherwise contoured to provide two separate areas or zones of contact
23
A and
23
B with the upper end portion
22
of receptacle
5
and/or the liner
7
as best shown is FIG.
4
and as will be hereinafter further described. The areas
23
A and
23
B extend peripherally around at least a substantial portion and as shown the entirety of the interior of the lower end portion
20
. The areas
23
A and
23
B are spaced apart in the direction of the longitudinal axis of the container
1
. This is a vertical separation when the container
1
is in its normal upright position.
The port
17
(
FIG. 5
) provides an opening
24
through the side wall
15
permitting the placement of waste into the interior
19
of the receptacle
5
, and liner
7
if used. Because of the contour of the side wall
15
which expands in perimeter downwardly and outwardly, the top portion
25
of the opening
24
(FIG.
2
and
FIG. 5
) is spaced inwardly toward the longitudinal axis of the container
1
less than the bottom portion
27
. Because the plane of the port
17
is generally vertical, a sill
28
is formed in the side wall
15
adjacent the bottom portion
27
of opening
24
. Preferably the sill
28
slopes downwardly and outwardly away from the opening
24
to provide for runoff of liquids such as rain or spilled material from the waste products. This helps prevent unnecessary moisture or other liquids from entering the container and contaminating the waste products particularly if such waste products are to be recycled. The opening
24
has a flange portion
30
(
FIG. 5
) surrounding the opening for attaching the door
33
as will be hereinafter explained. The sill
28
and flange
30
are preferably formed during the molding process of the cover
3
forming an integral assembly. The opening
24
may be formed by cutting or machining such as with a rotary cutter or the like. The opening
24
provides access from the exterior of the cover
3
to the interior of the receptacle
5
.
The door
33
is provided to substantially or completely close and seal the opening
24
providing selective access through the door into the interior of the container
1
as best illustrated in FIG.
5
. Any suitable door can be provided and is preferably of the self closing type and is also operable to help prevent the depositing of certain types of debris or waste in the container
1
. In the illustrated structure, the preferred embodiment of door
33
is a multi-flap type door formed by cutting a series of generally radially projecting slots or cuts
34
from a central point
35
. The cuts
34
form a plurality of generally V-shaped flaps
36
. The door
33
is preferably made of a resiliently deformable polymeric material such as vinyl or rubber which can be easily cut and is durable and resistant to failure from fatigue. The length of the cuts
34
and the flexibility of the door material will determine and control the size of waste products that can be placed into the container
1
and will help prevent the placement of undesirable refuse into the container
1
. For example, the container
1
is advantageously designed to accept beverage bottles and containers at a sports park or the like. The structure and rigidity of these containers is sufficient to effect deformation of the flaps
36
when those containers are inserted through the opening
24
and door
33
. On the other hand, paper debris and other such soft material do not have enough rigidity to effect deformation of the flaps
36
making it difficult to deposit paper or other soft material in the container
1
. The door
33
thereby limits, to some degree, the type and size of waste that can be deposited in the container
1
. The container
1
may be advantageously used in association with other types of trash containers at a location. The door
33
is suitably secured to the flange
30
, for example, through the use of a ring or collar member
32
which is received over and around a peripheral portion of door
33
through the use of conventional fasteners
37
. A peripheral portion of the door
33
is captured between the ring member
32
and flange
30
.
The receptacle
5
, as best illustrated in
FIGS. 1 and 3
, includes a bottom floor
41
and an upstanding side wall
43
integral therewith. The side wall
43
includes an enlarged collar
45
adjacent the bottom floor
41
, the collar
45
having an upper flange
46
defining the top part of the collar
45
. The flange
46
projects generally radially outwardly from a generally straight section
47
of side wall
43
, which straight section is generally cylindrical in the illustrated structure. At the upper portion
22
of the receptacle
5
, an enlarged collar
49
is provided. At the lower end of collar
49
there is provided a flange
50
projecting outwardly from the substantially straight side wall section
47
(FIG.
4
). The straight section
47
and flanges
46
and
50
define a peripheral recess
52
that can be utilized to display a graphic panel
53
or other advertising indicia. The recessed area
52
may extend around the entirety of the receptacle
5
, if desired. In the illustrated structure, there are a plurality of hangers or retainers
51
which cooperate with the display panel
53
to removably mount the panel
53
to the exterior of the receptacle
5
preferably in the recessed area
52
such that the outer face of the panel is spaced inwardly from the outer perimeter of each of the collars
45
and
49
. The hangers
51
are projections preferably molded at the time of molding the container
1
but may also be separate elements suitably secured to the receptacle
5
.
The upper end
22
of the receptacle
5
has a portion thereof mating with the lower portion
20
of the cover
3
to provide for removable mounting of the cover
3
to the receptacle
5
as best shown in
FIGS. 1 and 3
. In the illustrated structure, the upper end
22
includes an upper upstanding lip
57
having an upper end portion
58
defining the perimeter to the opening of the mouth
55
. The outer periphery of the lip
57
is sized and shaped to be received within the mouth
21
of the cover
3
and it is also sized and shaped to receive thereover the upper portion of the liner
7
. At the lower end of the lip
57
there is provided an outwardly extending shelf
60
terminating at its outer end into a rim portion
62
that is sized and shaped similar to the inside of the lower end
20
of the cover
3
for receipt therein, preferably with a slight amount of interference fit. Extending outwardly from the lower end of the rim portion
62
is another rim portion
63
forming a ledge
64
that has an outer dimension larger than the lower end
20
of the cover
3
to limit axial movement of the cover
3
onto the upper end of the receptacle
5
. The perimeter of the rim portion
62
is larger than the perimeter of the lip
57
. This provides for a snug fit between the liner
7
and the lip
57
and/or the rim portion
62
to ensure that the liner
7
stays in position in the receptacle
5
during use. Further, the lower end
20
of the cover
3
is tapered or otherwise contoured as best illustrated in
FIG. 4
to provide two separate peripheral areas of contact
23
A and
23
B between the inside surface of the cover
3
and the outer surface of the upper end
22
of receptacle
5
to frictionally engage the liner
7
between at least one of the areas of contact
23
A and
23
B and preferably between both areas of contact between the cover
3
and receptacle
5
around at least a portion of the perimeter of the receptacle
5
and preferably the entire perimeter. The perimeter of area
23
A is smaller than the perimeter
23
B to accommodate the taper of the lower end
20
. The liner
7
may be secured through either contact with the lip
57
and/or with the rim portion
62
. A gap
61
is formed between a lower portion of the lip
57
and the inside of the lower end
20
of cover
3
to help prevent contact between the liner
7
and a portion of both the inside surface of the lower end
20
of cover
3
and the outside surface of the lip
57
. The use of a plurality of different sized lip and rim portions on the upper end of the receptacle
5
permits for size variation in the liner
7
while still ensuring a snug fit of the liner
7
with at least one portion of the receptacle
5
.
It is also desirable to ensure that the cover
3
not become separated from the receptacle
5
when removed. It has been found advantageous to provide the flexible link member
9
having opposite end portions
65
and
66
thereof secured respectively to the cover
3
and receptacle
5
(FIG.
3
). Preferably the link member
9
is a flexible metal cable or rope having the opposite ends
65
and
66
each respectively secured to the cover
3
or the receptacle
5
. Preferably the entirety of the link member
9
is contained within the cover
3
and/or receptacle
5
when the cover
3
is installed on the receptacle
5
. This can advantageously be accomplished by the use of a flexible cable having a small diameter (e.g., about {fraction (1/16)} inch to about ⅛ inch). A thin flat strap may also be used. A portion of the cable
9
can simply be bent over the lip
57
and can be positioned between the liner
7
and the lip
57
on both sides of the lip as best illustrated in FIG.
6
. In this arrangement, the link member
9
does not interfere with the installation or removal of the cover
3
. It also provides a means to assist in the removal of the liner
7
from the receptacle
5
by simply pulling the link member
9
which would remove a portion of the upper end of the liner
7
from the receptacle
5
. In the illustrated structure, the link member
9
is secured at opposite ends to couplers or other attachment devices
67
. To simplify molding, it is preferred that the couplers
67
be separate elements each secured to a respective cover
3
or receptacle
5
as, for example, through the use of screw connectors, adhesive means or by fusion.
As illustrated in
FIGS. 1
,
3
and
4
, the display panel
53
is constructed to be easily removable and installable on the exterior of the receptacle
5
. The panel
53
may include advertising indicia
68
printed thereon and can be made of a polymeric type material. In the illustrated structure, the panel
53
is releasably secured to the receptacle
5
via the use of any plurality of hangers or projections
51
. The hangers
51
include a stub
69
secured to and extending outwardly from the substantially straight side wall section
47
. An enlarged head
70
can be provided at the free end of each of the stubs
69
. Alternatively, the stub may be generally cylindrical without the enlarged head
70
. The panel
53
is provided with a plurality of through apertures
71
sized and shaped similar to the stub
69
and smaller than the head
70
. The panel
53
can be removably installed on the receptacle
5
by inserting a respective head
70
and stub
69
through a respective aperture
71
. Removal of the panel
53
can be accomplished by resiliently deforming the panel
53
and stretching it over the heads
70
associated with the plurality of hangers
51
used to hold the panel
53
in place. Use of the panel
53
enables the container
1
to be simply and economically customized and decorated for use at a specific location or to provide advertising for specific products and/or to display specific messages or other information. It is recognized and anticipated that other attachment mechanisms other than the hangers
51
may be used to removably attach the display panel
53
to at least a portion of the exterior surface of the base receptacle
5
.
The container
1
may also be provided with means to anchor the container at a specific location to help prevent it from being moved, for example, by high winds or the like. Preferably, during the molding process of the container
1
, one or more eyelets
73
can be molded into the receptacle
5
as best shown in
FIGS. 1 and 3
, each eyelet projecting from a lower portion of the receptacle
5
and each having an aperture
74
extending therethrough for receipt of an anchor rope or cable
75
or the like.
The container
1
including the cover
3
and the receptacle
5
can be made by a suitable molding process using a polymeric material which may be filled, if so desired, as, for example, with glass fibers to increase the strength and agility of the overall container. The material can be polypropylene, high density polyethylene or the like. A preferred molding process is a blow molding process, however, other molding processes may be used, for example, rotational molding. The techniques and molding conditions for such processes are well known in the industry. Any suitable color can be provided in the plastic to provide color throughout various portions of the container
1
. A preferred blow molding process will now be described.
Blow molding is typically done by either forming a parison which is then clamped within a mold after which air is injected inside the parison to blow it outwardly and into contact with the surfaces of the mold cavity, the pressure being sufficient to conform the plastic to the shape of the mold cavity. The plastic is allowed to cool sufficiently so that it is rigid enough to remove from the mold for further processing. Another form of blow molding can be done by forming a precursor, for example, by injection molding and then moving the precursor into a mold cavity. The precursor is then urged into contact with the cavity of the mold with air pressure. The molded container preform is then allowed to cool sufficiently to remove it from the mold. The cavity is in the shape of the molded container preform as seen in FIG.
2
. After molding, the plastic will shrink both from cooling and from the nature of the polymeric material as is well known in the industry. The mold is multi-piece and typically is a two piece mold.
In the present invention, the cover
3
and receptacle
5
are molded as a single piece or integral unit. As best illustrated in
FIG. 2
, the cover
3
and receptacle
5
are joined together by a web of material
79
which is integral with and connects the two component parts together. As described above, the upper end
22
of receptacle
5
has a perimeter smaller than the lower end
20
of cover
3
. The inside perimeter of the lower cover end
20
is approximately the same size as the outer perimeter of the rim portion
62
to provide a snug or slight interference fit when the cover
3
is mounted on the receptacle
5
. Because the cover
3
is molded simultaneously with the base receptacle
5
, the shrinkage of the two components is substantially the same allowing for the close fit as just described without having to hand select mating cover and receptacle components for proper fit. After removal of the formed container preform, the cover
3
is separated from the base receptacle
5
by removal of the web
79
. The web
79
may be removed by any suitable cutting device. After separation of the cover
3
from the receptacle
5
, the link member
9
is secured to both the base receptacle
5
and cover
3
by attaching the ends of the link member
9
to the couplers
67
. The couplers
67
are secured to the cover
3
and receptacle
5
prior to or after connection of the link member
9
thereto. The door
33
may then be installed. Holes are formed in the flange
30
to mate with holes in the securement ring
32
and with holes in the door
33
. Screw fasteners
37
or any other suitable fastening means can then be used to secure the ring member
32
and door
33
to the cover
3
. The anchor rope or cable
75
may then be secured to the eyelet
73
in any suitable manner. If desired, the panel
53
may also be installed.
FIGS. 7 and 8
show an alternative embodiment of the present invention. Much of the structure of the alternative embodiment is similar to or the same as the structure in
FIGS. 1-6
wherein like or similar parts of the embodiment shown in
FIGS. 7 and 8
are designated by the same numbers as used in the description of the first embodiment. Thus, a detailed description of the like or similar parts and construction of the alternative embodiment is not necessary. The embodiment shown in
FIGS. 7 and 8
illustrates a container
101
comprising a cover
103
and a base receptacle
105
. A liner
7
(not shown in
FIGS. 7 and 8
) can also be installed in the base receptacle
105
as described above. A weight
11
, also not shown in
FIGS. 7 and 8
, can also be contained in the base receptacle
105
. The cover
103
has a top portion
13
, a side wall portion
15
and a port
17
generally as described. The cover
103
also has a lower end portion
120
which has a generally cylindrical inside surface
123
for a purpose later described. Actual movement of the cover
103
onto the base receptacle
105
is limited by the lower edge
125
of the cover
103
engaging the support ledge
64
.
The collar
49
associated with the base receptacle
105
includes rim portions
62
and
63
. The support ledge
64
extends between the rim portions
62
and
63
. The base receptacle
105
includes an upper portion
129
and a tapered lead in portion
131
which extends between upper portion
129
and the rim portion
62
. The upper receptacle portion
129
extends from the lead in portion
131
to the open mouth
55
and has a perimeter smaller than the perimeter of rim portion
63
to provide clearance between the inner cover surface
123
and the upper receptacle portion
129
when the cover
103
is installed on the base receptacle
105
. The tapered lead in portion
131
facilitates mounting of the cover
103
onto the base receptacle
105
providing a transition from the upper receptacle portion
129
to the rim portion
62
. One or more peripherally extending rims or projections
135
and
137
extend around a substantial portion of the perimeter of the upper receptacle portion
129
. The rims or projections
135
and
137
are spaced apart in the direction of the longitudinal axis of the base receptacle
105
which is vertical when the base receptacle is in its normal upright position. The projections
135
and
137
project outwardly from the upper receptacle portion
129
and have a perimeter substantially equal to the perimeter of rim portion
62
. This provides at least two vertically (or longitudinally) separated peripheral zones of contact with the inner cover surface
123
