FIELD OF THE INVENTION

This invention relates to trash receptacles, and more particularly to a scent granule dispenser for a trash receptacle.

DISCUSSION OF RELATED ART

Trash receptacles, and particularly covered trashed receptacles, are notorious for producing bad odors after use for several weeks or months. Typically it is impractical to clean such trash receptacles regularly, and as a result the bad odors seem to compound over time. Further, it is easy to forget to add scenting or cleaning agents to trash receptacles upon emptying.

Therefore, there is a need for a device that will automatically disburse a scenting agent into the trash receptacle regularly. Such a needed invention would further provide an easy means of refilling the device with the scenting agent, and would allow for the amount of scenting agent dispersed to be adjustable. Such a needed device would disperse the scenting agent upon lifting of the trash receptacle lid and thereby work automatically to reduce offensive odors within the trash receptacle. Even if the trash receptacle lid is not lifted for a long period of time, such a needed device would still act to reduce offensive odors within the trash receptacle. The present invention accomplishes these objectives.

SUMMARY OF THE INVENTION

The present invention is a dispenser for dispensing scented granules, pellets or powder into a trash receptacle that has a lid with an aperture therethrough. The dispenser includes an enclosure having an open top end, a bottom end, and at least one peripheral wall. The enclosure includes a top flange proximate the open top end thereof. The top flange is adapted for fixing against a bottom side of the lid of the trash receptacle. The top flange has an inner opening and an outer peripheral edge. The enclosure is adapted for holding the scented granules within an internal volume therein.

A riser tube is fixed with the inner opening of the top flange and traverses the aperture of the lid. The riser tube includes a mounting mechanism on an outer surface thereof.

An attachment ring is cooperative with the mounting mechanism on the outer surface of the riser tube. The attachment ring is adapted for selective engagement with the riser tube to clamp the lid between the attachment ring and the top flange of the enclosure. The mounting mechanism may include threads cooperative with internal threads of the attachment ring, for example.

A selectively removable top cover is adapted for sealing an open top end of the riser tube. The top cover may further include external threads cooperative with internal threads of the open top end of the riser tube.

A portion control flange is fixed inside the enclosure proximate the bottom end thereof. A lower end of the portion control flange, along with the bottom end of the enclosure, together are adapted to segregate a predetermined portion of the scented granules contained in the enclosure when the enclosure is in a first upright orientation. A top end of the portion control flange is fixed with the at least one peripheral wall of the enclosure, the at least one peripheral wall having a discharge aperture therethrough below the portion control flange.

As such, in use, when the enclosure is placed in a second orientation inclined towards the discharge aperture the segregated scented granules slide between the portion control flange and the enclosure to exist the discharge aperture into the trash receptacle.

In some embodiments the enclosure includes a plurality of vent apertures, whereby scent from the scented granules within the enclosure is able to further waft into the trash receptacle.

In some embodiments the bottom end of the enclosure is open and further includes a selectively removable bottom cover adapted for sealing the open bottom end of the enclosure. The bottom cover may further include internal threads cooperative with external threads of the open bottom end of the enclosure.

Such a removable bottom cover may be adapted to adjust the volume of the enclosure at the bottom end that captures the segregated scented granules, such that the amount of segregated scented granules dispersed with each tilting of the enclosure from the upright orientation to the second orientation is adjustable.

The present invention is a device that automatically disburses scented granules into the trash receptacle regularly with each lifting of the trash receptacle lid. The present device further provides an easy means of refilling the device with the scented granules, and allows for the amount of scented granules dispersed to be adjustable. Even if the trash receptacle lid is not lifted for a long period of time, the present invention still acts to reduce offensive odors within the trash receptacle. Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.

FIGS. 1-3 illustrate a dispenser 10 for dispensing scented granules 15 into a trash receptacle 20 that has a lid 28 with an aperture 27 therethrough. Such scented granules 15 are typically 0.1 inches to 0.25 inches in diameter, although scented pellets or powder having other granular sizes (not shown) could also be used.

The dispenser 10 includes an enclosure 30 having an open top end 38, a bottom end 32, and at least one peripheral wall 35. The enclosure 30 includes a top flange 40 proximate the open top end 38 thereof. The top flange 40 is adapted for fixing against a bottom side 26 of the lid 28 of the trash receptacle 20. The top flange 40 has an inner opening 44 and an outer peripheral edge 46. The enclosure 30 is adapted for holding the scented granules 15 therein, and is preferably made from an injection molded or roto-molded plastic material.

A riser tube 50 is fixed with the inner opening 44 of the top flange 40 and traverses the aperture 27 of the lid 28. The riser tube 50 includes a mounting mechanism 60 on an outer surface 59 thereof. Such a riser tube 50 is preferably made from a rigid plastic material.

An attachment ring 65 is cooperative with the mounting mechanism 60 on the outer surface 59 of the riser tube 50. The attachment ring 65 is adapted for selective engagement with the riser tube 50 to clamp the lid 28 between the attachment ring 65 and the top flange 40 of the enclosure 30. The mounting mechanism 60 may include threads 130 cooperative with internal threads 140 of the attachment ring 65, for example. An outer surface of the attachment ring 65 may include a wrench-engageable nut structure 150 for facilitating tightening and untightening of the dispenser 10 onto the trash receptacle lid 28. The attachment ring 65 is preferably made from a rigid plastic or metal material.

A selectively removable top cover 70 is adapted for sealing an open top end 58 of the riser tube 50. The top cover 70 may further include external threads 160 cooperative with internal threads 170 of the open top end 58 of the riser tube 50 (FIG. 2). Further, the top cover 70 may further include a second wrench-engageable nut structure 180 for facilitating tightening and untightening of the top cover 70 with the riser tube 50. The top cover 70 is preferably made from a rigid plastic or metal material.

A rigid or semi-rigid portion control flange 80 is fixed inside the enclosure 30 proximate the bottom end 32 thereof. A lower end 85 of the portion control flange 80, along with the bottom end 32 of the enclosure 30, together are adapted to segregate a predetermined portion 16 of the scented granules 15 contained in the enclosure 30 when the enclosure is in a first upright orientation 90 (FIGS. 1 and 2). A top end 88 of the portion control flange 80 is fixed with the at least one peripheral wall 35 of the enclosure 30, the at least one peripheral wall 35 having a discharge aperture 36 therethrough below the portion control flange 80. The portion control flange 80 is preferably integrally formed with the enclosure 30, but may also be adhered or ultrasonically bonded thereto.

As such, in use, when the enclosure 30 is placed in a second orientation 100 (FIG. 3) inclined towards the discharge aperture 36 the segregated scented granules 16 slide between the portion control flange 80 and the enclosure 30 to exist the discharge aperture 36 into the trash receptacle 20. Typically the trash receptacle 20 is of the typing having the lid 28 pivotally attached thereto, and as such the dispenser 10 is installed with the discharge aperture 36 oriented towards the pivoted edge of the lid 28. With trash receptacles 20 having detached lids 28, the lid 28 when removed can be pivoted manually towards the discharge aperture 36. An indicia (not shown) may be included on the enclosure 30 or lid 28 to facilitating pivoting of the lid 28 in the correct direction in order to discharge the segregated scented granules 16.

In some embodiments the enclosure 30 includes a plurality of vent apertures 120, whereby scent from the scented granules 15 within the enclosure 30 is able to further waft into the trash receptacle 20.

In some embodiments the bottom end 32 of the enclosure 30 is open and further includes a selectively removable bottom cover 110 adapted for sealing the open bottom end 32 of the enclosure 30. The bottom cover 110 may further include internal threads 190 cooperative with external threads 200 of the open bottom end 32 of the enclosure 30 (FIG. 2). The bottom cover 110 preferably further includes a knurled peripheral edge 210 for facilitating manual tightening and untightening of the bottom cover 110 with the enclosure 30.

Such a removable bottom cover 110 may be adapted to adjust the volume of the enclosure 30 at the bottom end 32 that captures the segregated scented granules 16, such that the amount of segregated scented granules 16 dispersed with each tilting of the enclosure 30 from the upright orientation 90 to the second orientation 100 is adjustable. As such, the amount of dispersed segregated granules 16 can be adjusted higher for larger trash receptacles 20, or those needing more odor abatement, or adjusted lower for smaller trash receptacles 20 or those requiring less odor abatement, such as for recyclable items or paper trash.

To install the dispenser 10 on a pre-existing trash receptacle 20 and lid 28, if the lid 28 does not already have the aperture 27 then the aperture 27 may be cut into the lid 28. Thereafter the riser tube 50 of the enclosure 30 is inserted from the bottom side 26 of the lid 28 with the discharge aperture 36 towards the rear of the trash receptacle 20, that is, the pivoted edge of the lid 28. The attachment ring 65 is then installed from above to clamp the lid 28 between the attachment ring 65 and the top flange 40 of the enclosure.
