ABSTRACT:
FIELD OF THE INVENTION
The field of art to which the invention relates comprises the art of refuse disposal and liner bags internally dispensed from within the receptacle therefor.
1. Background of the Invention
The use of various receptacles for lightweight refuse disposal from the wastebasket to the portable trash bin are common-place and are widely provided on site. In domestic situations, most every room in the house includes at least-one refuse receptacle that may vary in size and shape depending as a matter of choice, on anticipated needs.
In recent years, many municipalities have begun requiring that refuse when ultimately discarded for pickup or dumping to be placed within a plastic liner bag for disposal. While commercially available and conveniently packaged in wound-up roll form when purchased, the liner bags are frequently regarded as an annoyance to install individually within the receptacle prior to placement of refuse therein. When filled, the bags are removed and discarded to a convenient site.
2. Background of the Prior Art
To minimize handling during individual installation of liner bags, various devices in the prior art have been developed that will accommodate the pre-wound roll package internally within the refuse receptacle so as to enable dispensing the liner bags seriatim one at a time. By means thereof, liner bags can be drawn directly from within the receptacle and installed in and about the receptacle as required. As the filled bag is withdrawn for disposal, the next bag, still attached is simultaneously withdrawn therewith. Exemplifying such prior art is the disclosure of U.S. Pat. No. 4,364,490.
While such dispenser devices of the prior art have undoubtedly functioned well, they are generally characterized as requiring specially designed receptacles in order to internally accommodate and dispense the package of pre-wound liner bags. As a consequence, such standard rolls cannot be accommodated in conventional unmodified receptacles without major modification and are therefore unsuitable for use as a retrofit installation for the receptacle after-market.
Despite recognition of the foregoing limitations, a ready solution therefore has not heretofore been known.
OBJECTS OF THE INVENTION
It is therefore an object of the invention to provide a novel structure for mounting a package of pre-wound liner bags for dispensing internally of a refuse receptacle.
It is a further object of the invention to effect the previous object with a structure conveniently adapted for installation as a retrofit in a pre-existing receptacle.
It is a still further object of the invention to effect the previous objects in a highly convenient, economical and expeditious manner.
SUMMARY OF THE INVENTION
This invention relates to apparatus for dispensing of pre-wound rolls of individual liner bags from within a refuse receptacle. More specifically, the invention relates to a bag dispenser apparatus installable within refuse receptacles that is greatly simplified as compared to previous installations therefor. At the same time, the apparatus is conveniently suitable, not only for fabrication by original receptacle manufacturers, but also on a retrofit basis.
To achieve the foregoing, there is provided a dispenser for receptacle installation comprising, an elongated removable holder or housing in which to receive and accommodate a packaged pre-wound roll of liner bags. The housing of plastic composition includes an elongated slot at its top surface for permitting one at a time withdrawal of liner bags from the roll. Installation within and about the receptacle includes a variety of anchor constructions at the standard floor of the receptacle enabling the housing to be removably secured thereat.
One anchor support embodiment includes an elongated channel-like support plate secured internally to the floor of the receptacle and having elongated oppositely parallel, inwardly turned side channels. The underside of the housing includes elongated turned out flanges oppositely parallel and suitable for a snap-in interfit within the side channels of the support. For replacing a pre-wound roll of liner bags, the housing flanges can be hand squeezed toward each other enabling the housing to be removed from the side channels. With a fresh roll in place, the flanges are similarly squeezed and then released for expansion outward to within the side channels.
A second anchor support embodiment includes a plurality of spaced apart hooks on both sides of the housing and a plurality of hooks secured in the floor of the receptacle. Hooks at corresponding locations are joined together by a removable elastic cord that when connected between paired hooks secure the housing in place. Freeing one or both ends of each cord enables the housing to be removed for receipt of a bag roll and then replaced.
For retrofit installation, either of the above embodiments can be conveniently added by merely securing the support channel and/or hooks to the receptacle floor as above.
The above noted features and advantages of the invention as well as other superior aspects thereof will be further appreciated by those skilled in the art upon reading the detailed description that follows in conjunction with the drawings.
