Abstract
A trash barrel receptacle or storage bin container includes a detached lid having a predetermined depth, which is held down with an elastic lid retainer. The garbage can or storage bin and lids use no physical locks or canvas straps, but include the elastic lid retainer, which avoids the need for a pivotable handle located near the top of the garbage can or storage bin, to lock the lid over the garbage can or storage bin. The lid has a central portion with a concave groove or channel to retain the bungee cord within, to prevent the lid from sliding off laterally off of the refuse barrel or storage bin.

DETAILED DESCRIPTION OF THE DRAWINGS
(18) The present invention has broad applications to many technical fields for a variety of articles. For illustrative purposes only, a preferred mode for carrying out the invention is described herein, wherein a trash barrel receptacle utilizes a cover lid, including a locking connection of respective bosses extending down from the lid to respective cutout grooves in the top of the barrel receptacle, as well as an optional elastic securement retainer for the cover lid.
(19) The outdoor trash barrel of this invention has a cover lid and cover lid retainer that is convenient for the homeowner as well as the trash collector. Injury exposure to sanitation workers engaged in manual dumping operations into trucks is minimized.
(20) FIG. 1 depicts a sanitation worker 5 manually dumping the contents of a trash barrel into the hopper of a truck 7 using a prior art trash barrel receptacle 1 with a pivoted cover lid 3. It is noted the potential for injury by the moving cover lid 3 potentially striking the sanitation worker 5 while the sanitation worker quickly lifts and inverts the barrel for dumping refuse therefrom into a bib collector of a sanitation truck.
(21) The first embodiment of the present invention shown in FIGS. 2 and 3 is for a trash barrel receptacle combination 10 with a barrel 12 that is essentially round in cross section while a second embodiment shown in FIGS. 11 and 12 illustrates an essentially rectangular cross section trash barrel receptacle combination 50 with comparable features, such as barrel 54 and cover lid 52.
(22) FIG. 2 shows a sealed round cross section trash barrel receptacle combination 10 of this invention with barrel 12, and removable cover lid 14, which is lockably connected to the top shirt of barrel 12 with protruding bosses 36 engageable with cutout grooves at the top of barrel 12, and which is further optionally held down with an expandable elastic securement element, such as an optional bungee cord 18, where the optional bungee cord 18 is secured in place within optional concave recess channel 34 extending axially lengthwise within a raised rib handle portion 20 of the barrel 12, where the concave recess channel 34 preferably has a narrow width of about one half to three quarters of an inch.
(23) FIG. 3 is an exploded view of the same trash barrel receptacle combination 10 showing the components more clearly. FIG. 3 shows the barrel 12 oriented and rotated 180 degrees than how barrel 12 is shown in FIG. 2. It is noted that cover lid 14 is shown in FIG. 3 having a depth of about 4 to 5 inches in depth “D, fitting loosely but smoothly via cover skirt 22 fitting over barrel skirt 24 at the top end of barrel 12. The depth “D” is several inches deeper than the conventional 2 inch depth of conventional garbage can lids. Barrel side handle 16 can be either molded in place, or it can be pivotable. An optional quick-disconnect/connect bungee cord securement fastener 28 is molded to one side of barrel 12 (as shown in the enlarged close-up detail view in FIG. 4). The optional molded securement fastener 28 extends outwardly from the outer surface of barrel 12. In order to hold the proximal end hook 18b of the optional bungee cord 18 in place, a slot extends preferably partially and slanted at a downward angle from the top of securement fastener 28, towards the outer surface of barrel 12. This type of structural configuration of the slot can mate with the bungee cord proximal fastener end 18b, to hold proximal end hook 18b in place indefinitely, or the proximal end hook 18b can be removed by the user each time used, if preferred by the user. It is further noted that use of the bungee cord 18 is optional, since the lid 14 can be lockable in place to the top of the barrel 12 by virtue of the engagement of the downwardly extending bosses 36 of the cover lid 14 with corresponding cutout grooves 26 at the top of the barrel 12.
(24) As shown in FIGS. 5 and 6, a different optional securement fastener 30 is provided, for quick and convenient dislodging of distal end hook 18a of the optional bungee cord 18 by a sanitation worker, immediately before lifting the cover lid 14 off of the barrel 12. Securement fastener 30 is located on an opposite side of barrel 12, which is preferably an eyelet, wherein the eyelet is a safer option than a hook. The opposite distal fastener end 18b of optional bungee cord 18 is retained in annular eyelet 30, as shown in close-up detail views of FIGS. 3, 5 and 6 on the opposite side to securement fastener 28. Since bungee cord 18 is optionally used to deter animals' access to the contents of barrel 12 of barrel receptacle combination 10, the homeowner may wish to keep it attached to eyelet 30 even when not in use to prevent loss. In such cases, the distal end fastener open hook 18b shown in FIG. 6 can be easily replaced with a snap hook or other closed retainer.
(25) The remaining details are regarding the handling of the optional bungee cord 18 and the fit of the cover lid 14 and barrel 12 of the barrel receptacle combination 10. Cover lid 14 has a raised central rib handle 20 with an optional concave groove or channel 34 to retain the optional bungee cord 18 within (if used), when it is in use to prevent cover lid 14 from sliding off laterally off of barrel 12 of barrel receptacle combination 10. While this feature can be seen in FIGS. 2 and 3, the central enlarged view of FIG. 7 and sectional views of FIGS. 8 and 9 are more revealing. At the inside ends of central rib feature 20 are convex bosses 36, molded to fit in concave grooves 26 (see FIG. 3) at the top of smooth surfaced upper skirt 24 of barrel 12. Although they could be provided extending down from raised rib handle 20 without a concave groove or channel recess 34, these convex bosses 36 are preferably convex mirror images of the lower concave portions of the walls forming the concave recess channel 34 of the cover lid 14. These bosses 36 also align the optional bungee cord 18 with the retaining proximal and distal securement fasteners 18a and 18b, and put the cover lid 14 in positional registration with the barrel 12 and lock the lid 14 to the barrel 12, of the barrel receptacle combination 10, with or without the optional elastic bungee cord 18 and optional channel 34 of raised rib handle portion 20.
(26) FIG. 8 also shows that cover lid 14, as is also shown in FIG. 3, as having the smooth surfaced skirt 22 with depth “D” of about 4 to 5 inches in depth, so that cover lid 14 with cover skirt 22 fits smoothly and firmly over barrel skirt 24 at the top end of barrel 12. FIGS. 7 and 9 are close-up detail views that show left and right cover handles 32 which are integrally molded with raised central rib 20, and which are preferably arcuate at their outer edges, to facilitate manual grasping by the user. As also shown in FIGS. 7 and 9, cover lid 52's raised central rib 20 also includes left and right cover handle tabs 32, which are preferably arcuate at their outer edges, to facilitate manual grasping by the user, which are integrally molded with raised central handle rib 20. Preferably cover handle tabs 32 comprise a pair of centrally located outwardly extending cantilevered flanges, each cantilevered flange extending in a opposite direction to provide opposite gripping surfaces for manually handling the lid 14.
(27) FIGS. 11 and 12 show a second embodiment of this invention using a trash barrel receptacle 50 with generally rectangular cross section. Cover lid 52 seals barrel receptacle 54 using optional bungee cord 18 and all of the hardware and techniques of the first embodiment shown in FIGS. 1-10. For example, cover lid 52 also has a descending, smooth surfaced skirt having a deeper depth “D” than conventional lids having depths of about 2 inches, which slides over a smooth surfaced upper skirt with a similar corresponding depth “D” at the top of barrel receptacle 54. Although cover lid 52 can be locked in place by virtue of bosses 36 of lid 52 engaging cutout recess grooves 26 on the top of barrel receptacle 52, cover lid 52 also has a raised central rib handle 20 with an optional concave groove or channel 34, to retain optional bungee cord 18 within, to further prevent cover lid 52 from sliding off laterally off of trash barrel 54 of barrel receptacle combination 50. The optional concave recess channel 34 also preferably has a narrow width of about one half to three quarters of an inch.
(28) As also shown in FIGS. 2, 3, 7, 8 and 9, the central rib 20 also has convex bosses 36 molded to fit in grooves 26 at the top of upper skirt 55 of rectangular shaped barrel 54, for aligning and locking lid 52 to barrel receptacle 54. These bosses 36 also align the optional bungee cord 18 with the optional retaining proximal and distal securement fasteners 18a and 18b, and also put the cover lid 52 in positional registration with the rectangular barrel 54. As also shown in FIGS. 7 and 9, cover lid's 52 raised central rib 20 also preferably includes left and right cover handle tabs 32, which are preferably arcuate at their outer edges, to facilitate manual grasping by the user, which are integrally molded with raised central rib 20. Preferably cover handle tabs 32 comprise a pair of centrally located outwardly extending cantilevered flanges, each cantilevered flange extending in a opposite direction to provide opposite gripping surfaces for manually handling the lid 52.
(29) Rectangular barrel 54 also includes a barrel side handle 16, which can be either molded in place or it can be pivotable. Similarly, an optional quick-disconnect/connect bungee cord securement fastener 28 is optionally molded to one side of barrel 54, such as shown in FIG. 4, which mates with the proximal fastener end 18a of optional bungee cord 18. Likewise, the opposite distal fastener end 18b of optional bungee cord 18 is retained in eyelet 30 shown in close-up detail views of FIGS. 5 and 6, on an opposite side (not shown) of barrel 54, on the opposite side to securement fastener 28.
(30) FIGS. 13 and 14 show a first alternate embodiment of this invention using a stackable storage bin 150 with a generally rectangular cross section. Cover lid 152 seals storage bin container receptacle 154 using bungee cord securement device 118, as well as some of the hardware and techniques of the first embodiment shown in FIGS. 1-12. For example, cover lid 152 also has a descending, smooth surfaced skirt 152a having a depth which slides over a smooth surfaced upper skirt 155 of container 154 of stackable storage bin 150, with a similar corresponding depth at the top of storage bin container receptacle 154. Cover lid 152 can be locked in place over storage bin container 154 by virtue of convex bosses 136 of lid 152 engaging cutout recess grooves 126 on the top of storage bin container receptacle 154. Cover lid 152 also has a raised central rib handle 120 with a concave groove or channel 134, to retain bungee cord 118 within, to further prevent cover lid 152 from sliding off laterally off of receptacle bin 154 of the storage bin container combination 150. The concave recess channel 134 also preferably has a narrow width of about one half to three quarters of an inch to accommodate the diameter of the bungee cord securement device 118 snugly therein.
(31) As also shown in FIG. 14, the central rib 120 may optionally have convex bosses (not shown) molded to fit in grooves (not shown), at the top of upper skirt 155 of rectangular shaped stackable storage bin container 154, for aligning and locking lid 152 to storage bin container receptacle 154. These bosses, similar to those shown in FIGS. 8, 10 and 12 herein, also align the optional bungee cord 118 with the retaining proximal and distal securement retainer fasteners 119 on the side of storage bin receptacle 154, to hold distal fasteners 118a of bungee cord 118, with eyelets 130 of retainer fasteners 119, and also put the cover lid 152 in positional registration with the rectangular storage bin container 154. As also shown in FIGS. 7 and 9, cover lid 152's raised central rib 120 also optionally includes left and right cover handle tabs similar to handle tabs 32, such as in FIGS. 7, 9, 11 and 12, which are preferably arcuate at their outer edges, to further facilitate manual grasping by the user, and which are integrally molded with raised central rib 120. Preferably cover handle tabs 32 comprise a pair of centrally located outwardly extending cantilevered flanges, each cantilevered flange extending in a opposite direction to provide opposite gripping surfaces for manually handling the lid 152.
(32) Rectangular stackable storage bin container 154 also includes a pair of oppositely positioned storage bin container handles 116, which can be either molded in place or it can be pivotable. Similarly, an optional quick-disconnect/connect bungee cord securement fasteners 119 are optionally molded to each side of storage bin container 154, such as shown in FIGS. 13 and 14, which each mate with the proximal fastener end 118a of bungee cord securement device 118. Likewise, the opposite distal fastener end 118b of bungee cord securement device 118 is retained in eyelet 130 of retainer 119 shown in close-up detail views of FIG. 14, on an opposite side (not shown) of storage bin container 154, on the opposite sides or ends thereof. It is further noted that the bottom of storage bin container 154 has a mirror image structure to mate with the top of a similar storage bin container and lid 152 underneath, such as an upwardly extending channel (not shown) to accommodate upwardly extending raised rib 120 of lid 152 of the storage bin container 150 above.
(33) FIGS. 15 and 16 show a further alternate embodiment of this invention using a storage bin container receptacle and lid combination 250 with generally rectangular cross section. Cover lid 252 with flat top surface 253 seals storage bin container receptacle 254 using optional bungee cord 218 and some of the hardware and techniques of the first embodiment shown in FIGS. 1-14. For example, cover lid 252 also has a descending, smooth surfaced skirt 252a having a depth which slides over a smooth surfaced upper skirt 255 with a similar corresponding depth at the top of storage bin container receptacle 254 of receptacle and lid combination 250. Although cover lid 252 can be locked in place by virtue of bosses 236 of lid 252 engaging cutout recess grooves 226 on the top of storage bin container receptacle 254, flat topped cover lid 252 also has a downwardly extending concave groove or channel 234, to retain optional bungee cord 218 within, and to further prevent cover lid 252 from sliding off laterally off of receptacle 254 of storage bin receptacle combination 250, such as, for example, an insulated cooler. The concave recess channel 234 also preferably has a narrow width of about one half to three quarters of an inch.
