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


for removably mounting the cover


103


onto the base receptacle


105


. A flexible bag liner


7


can be inserted into the interior of the base receptacle


105


having its upper end wrapped over the upper portion


129


and down over the rims or projections


135


and


137


and will be retained between and held in place by the engagement of the inner cover surface


123


with the rims or projections


135


and


137
