Description
Background of the Invention
The present invention relates to a hoop retainer for securing disposable trash bags in a trash can.
Trash bags, which typically comprise a flexible plastic material such as mylar, are employed to protect the inside of the trash can and to keep the trash can clean. In the case of metal trash cans, the prevention of garbage and other detritus from contacting the metal sides and bottom will considerably reduce the possibility of corrosion thereof.
Attempts to use disposable trash bags in conjunction with trash cans is often frustrating. Usually, the trash bag is opened and placed in the trash can, and the open end is draped over the open end and upper side of the trash can.
However, the weight of trash often causes the trash bag to partially or completely slip inside the trash can, with the consequence that the trash bag is difficult to retrieve, especially without tearing the trash bag due to the weight of the trash. Such tearing, of course, defeats the purpose of employing the trash bag, and results in dirtying the inside of the trash can.
A means of retaining the trash bag in position is desired that is easy to use and may be retrofitted on existing trash cans.
Objects and Summary of the Invention
Accordingly, it is an object of the present invention to provide a trash can retainer.
It is another object of the present invention to provide a trash can retainer in hoop configuration for removeable securement to a trash can.
It is yet another object of the present invention to provide a trash can hoop retainer that is hingedly attachable to the trash can and provided with means for removable retention of trash bags.
It is a further object of the present invention to provide a trash can hoop retainer that may be retrofitted to existing trash cans.
Briefly, a trash can retainer is provided for retaining trash bags in removable securement in a trash can having two lifting handles and a rim. The retainer comprises a rod-like body of substantially circular or hoop-like configuration, with means on one side for hingedly engaging in one of the handles of the trash can and means on the opposite side therefrom to engage the rim above the second of the handles of the trash can in clamping relationship to thereby engage a top portion of the trash bag in friction-fit relationship.

Detailed Description of the Invention
Referring now to the drawing wherein like numerals of reference designate like elements throughout, the upper portion of a trash can 10 is depicted in FIG. 1, with a trash bag 12 secured therein. The trash can 10 is of the type provided with an overhanging, downwardly depending rim 14, which defines top 16 of the trash can 10.
The rim 14 may have a downwardly depending portion or skirt, as is common. However, the retainer of the invention will be better maintained in place if, as shown more clearly in FIG. 3, the rim 14 includes an inner downwardly depending portion 14a and an outer downwardly depending skirt portion 14b connected therewith by a support concavity 14c. The retainer may then be supported in the support concavity 14c.
The trash can 10 is also provided with a pair of opposed handles 18, 20 and a cover 22. The handles 18, 20 are conveniently made of the same material as the trash can, such as a high impact plastic, although metal, such as galvanized steel, may alternately be employed as either the trash can, the handles or both. The handles are preferably integral with the body of the trash can 10 and extend outwardly therefrom.
In accordance with the invention, a trash can hoop retainer 24 is employed to retain the trash bag 12 in the trash can 10.
FIG. 2 depicts in exploded perspective view the relationship between the trash can 10, its cover 16 and the trash can hoop retainer 24 of the invention. There, it is seen that the retainer 24 is a rod-like body of substantially circular or hoop-like configuration.
The circular configuration is not continuous, however. The retainer 24 comprises two opposed annular members 26a, 26b joined on one side by outwardly projecting radial members 28a, 28b integrally formed therewith, in turn connected to either side of a downwardly depending U-shaped member 30, also integrally formed therewith. The U-shaped member 30 is adapted to be cooperatively associated with the bottom of the downwardly depending skirt portion 14b of the rim 14 in clamping arrangement.
At the opposite end of the retainer 24, the two opposed annular members 26a, 26b terminate in open ends, each comprising a first outwardly projecting radial member 32a, 32b, a downwardly depending member 34a, 34b, a second outwardly projecting radial member 36a, 36b in a plane below that defined by the annular members 26a, 26b, and an inwardly disposed tang member 38a, 38b (only 38b being visible in the drawings), with all members 32a, 34a, 36a and 38a being integral with annular member 26a and with all members 32b, 34b, 36b and 38b being integral with annular member 26b.
The tang members 38a, 38b are cooperatively associated in holes 40 in handle 18 in rotatable relationship, thereby providing a hinge movement to the retainer 24 formed by the axis connecting the holes 40 in the handle 18. Indeed, the retainer 28 may be rotated to a rest position along the side of the trash can 10, downwardly depending from the handle 18. To accommodate such rotation, the holes 40 are slightly larger than the outside diameter of the tang members 38a, 38b.
Advantageously, a wire of steel or other metal is suitably employed in the fabrication of the retainer 24 of the invention, although certain plastic materials having sufficient strength and adequate resiliency may alternately be utilized.
While new trash cans may be fabricated with the holes 40 suitably located in the handle 18, existing trash cans may be modified to accept the retainer 24 of the invention by drilling holes of an adequate diameter and depth to accommodate the tang members 38a, 38b.
In operation, a trash bag 12 is opened and placed in the trash can 10, with its upper edges 12a draped over the rim 14 thereof. The retainer 24 of the invention is rotated so that it provides clamping along the rim 14 by the annular members 26a, 26b. In particular, the retainer 24 is maintained in the support concavity 14c. The U-shaped member 30 is urged downward so as to engage the bottom of the skirt 14b of the rim 14 in friction-fit, clamping relationship.
When it is desired to remove the trash bag 12 from the trash can 10, the U-shaped member 30, being yieldable, is pulled slightly away from the rim 14 to disengage the U-shaped member from the bottom of the skirt 14b, and the retainer 24 is rotated out of clamping position and into its rest position along the side of the trash can 10, thereby permitting the trash bag 12 to be lifted out of the trash can 10.
Thus, a trash can hoop retainer has been disclosed. Many changes and modifications will readily occur to those of skill in the art, and all such changes and modifications are within the scope of the invention, as defined by the appended claims.
