## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application is a continuation of U.S. patent application Ser. No. 16/529,476, filed Aug. 1, 2019, which claims the benefit of priority of U.S. Provisional Patent Application No. 62/714,192, filed Aug. 3, 2018, of which the disclosures are hereby incorporated by reference and to which priority is claimed.


FIELD OF THE INVENTION
The present invention generally relates to closure devices for waste containers, particularly residential and commercial waste containers. In particular, the invention relates to a waste container closure device which prevents the lid from opening when the container is accidentally tipped over on its side.
BACKGROUND
As is well known, residential and commercial waste containers for use in residential or commercial applications, typically include a base structure selectively covered by a hinged lid. These containers usually contain a block-shaped container with a hinged lid attached to one side thereof. The containers may be emptied by an automated lifting device on certain waste removal vehicles, which tilts the waste containers for emptying the contents of the waste containers. The containers are usually lifted by the lifting mechanism and pivoted in some fashion, so that the hinged top of the container opens and the trash contained therein is emptied into the vehicle. The container is then returned to a position on the ground, and the hinged lid closes the top of the container.
The waste containers may be available for purchase by home owners from various home improvement or department stores. When the container is in an upright position, the lid is closed and prevents animals from accessing the waste within the container. However, when the container is tipped over on its side, e.g. by animals or by strong wind, the lid may open, spilling the contents of the container or allowing animals to access the interior of the container.
Therefore, there remains a need for a simple and inexpensive device that prevents the unintended opening of the waste container, such as by an accidental knockdown by wind or animals, or an accidental opening of the lid by gusting wind.
SUMMARY OF THE INVENTION
The present invention provides a closure device for a waste container that keeps the lid of the container closed when the container is knocked over on its side. The closure device, however, may be manually opened by a user for depositing waste or for a dumping operation. An aspect of the present invention provides a closure device that is designed to be mounted to the waste container. The closure device contains two straps, two mounting devices configured to mount on opposing sides of the container, and at least one elastic member connected to one or both of the straps. The straps are configured to pass through the mounting devices and to connected together over the lid of the container to prevent the lid from opening.
Another aspect of the present invention provides a waste container having the closure device mounted thereon.
Methods for making the different aspects of the present invention are also provided.
Other aspects of the invention, including apparatus, devices, kits, processes, and the like which constitute part of the invention, will become more apparent upon reading the following detailed description of the exemplary embodiments.

FIG. 1 illustrates a top portion of a waste container 2, such as a trash container typically used by home owners or businesses to deposit, retain, or store trash awaiting pick-up by a trash removal vehicle. The container 2 may be tilted or otherwise pivoted from an upright storage position (as shown in FIGS. 1-3) to a tilted or dumping position to empty its contents.
The container 2 has at least one lid 4 on top of a main box 6 that is open in order to expose the open interior. Box 6 defines an interior volume for holding waste. In a preferred embodiment, as shown in FIGS. 1-3, the main box 6 contains four walls: a front wall 6a, a rear wall 6b opposing the front wall 6a, a right wall 6c connecting the front wall 6a and the rear wall 6b, and a left wall 6d opposing the right wall 6c and also connecting the front wall 6a and the rear wall 6b. The lid 4 is mounted on a lid hinge 8, typically at the rear of the container 2, so that when an upward force is applied to the distal end of the lid 4, the lid 4 opens by pivoting on the lid hinge 8.
A closure device 100 is mounted to the container 2. The closure device 100 contains two straps: a right side strap 102a and a left side strap 102b, as best shown in FIG. 1 Two mounting devices are positioned on opposite sides of box 6 near the open top: a right side mounting device 104a and a left side mounting device 104b. One or more elastic members 106 are likewise positioned at the open top of box 6. There preferably two elastic straps 106, which are positioned on opposite sides of box 6. Henceforth, unless otherwise indicated, “elastic member 106” or the like should be read to include one or more elastic members. Both straps 102a, 102b are preferably identical. As such, any description of one of the straps also pertains to the other. Further, the mounting devices 104a, 104b are mirror images of each other and contain the same parts. As such, any description of one of the mounting devices also pertains to the other, albeit in a mirror image. The closure device 100 may be in the closed position (see FIG. 1) or the opened position (see FIG. 2). In the closed position, the straps 102a, 102b are connected to each other on top of the lid 4 to prevent the lid from opening (see FIG. 1). In the opened position, the straps 102a, 102b are disconnected at one end and retracted away from the lid 4 toward the mounting devices 104a, 104b to allow the lid 4 to be opened (see FIGS. 2-3).
The right side mounting device 104a is mounted on the right wall 6c; and the left side mounting device is mounted on the left wall 6d of the container 2. The right side mounting device 104a will be described herein with the understanding that a mirror image thereof (the left side mounting device 104b) is also mounted on the left side wall 6d. As shown in FIG. 4, the right side mounting device 104a contains a base plate 300 having one or more holes 302 therein for attaching the right side mounting device 104a to the right side wall 6c of the container 2. Mechanical fasteners, such as screws, nut/bolts, rivets, etc., may be placed through the one or more holes 302 to fix the right side mounting device 104a to the right side wall 6c. Alternatively, the right side mounting device 104a may be adhesively attached to the right side wall 6c, e.g., by glue. Preferably, the right side mounting device 104a is placed on the right side wall 6c in a position close to the lid 4 and the front wall 6a, near the uppermost portion of box 6. The base plate 300 contains opposing upper block 304 and lower block 306 protruding outwardly from the base plate 300. The upper and lower blocks 304, 306 position and locate a pin 308 to the right side mounting device 104a. Preferably, the pin 308 is threaded on one end, extends through a through hole (not shown) in the lower block 306 and threadedly engages a hole 310 (see FIG. 5) in the upper block 304. Here, the treaded end of the pin 308 is crewed into the hole 310 and is secured therein. When properly located in position, the pin 308 provides a gap 312 between itself and the base plate 300 for passage of the right side strap 102a therethrough, as best shown in FIG. 4. When mounted on the right side wall 6c, the right side mounting device 104a is positioned such that the upper block 304 is located closer to the lid 4 and the front wall 6a than the lower block 306. That position places the pin 308 at an angle about 40-50° to the horizontal, as best shown in FIG. 1, preferably about 45°.
As shown in FIGS. 1 and 2, the right side strap 102a contains a front end 103a and a rear end 105a. The front end 103a is fed horizontally through the gap 312 (see FIG. 4) between the pin 308 and the base 300. It should be understood that any description herein of the right side strap 102a also pertains to the left side strap 102b as it relates to the left side mounting device 104b. Preferably, two elastic members 106a and 106b are used. The rear end of the right side strap 102a is connected to a first end of the first elastic member 106a (see FIG. 7), preferably via a D-ring 108a. The second end of the first elastic member 106a is connected to the left side mounting device 104b (the mirror image of FIG. 6). Similarly, the rear end of the left side strap 102b is connected to a first end of the second elastic member 106b (the mirror image of FIG. 7). The second end of the second elastic member 106b is then connected to the right side mounting device 104a (see FIG. 6).
Alternatively, one elastic member 106 may be used. In that case, the rear end of the right side strap 102a is connected to the rear end of the left side strap 102b via the elastic member 106. The elastic member 106 may be, e.g. a bungee cord, having one end connected to a ring 108a at the rear end of the right side strap 102a and the other end connected to a ring 108b at the rear end of the left side strap 102b. Although rings 108a, 108b are shown in the drawings, the elastic member(s) 106 may be connected to the straps 102a, 102b via other mechanisms, such as holes, loops, etc. on the straps 102a, 102b. The elastic member(s) 106 horizontally connect the left side strap 102b to the right side strap 102a. Preferably, the elastic member(s) 106 is positioned around the rear wall 6b of the container 2 (see FIG. 3).
The free ends (the ends that are not attached to the elastic member 106, also referred to herein as the front ends 103a, 103b) of the straps 102a, 102b contain connectors 110a, 110b that allow those free ends to connect to each other (see, e.g., FIG. 1). The connectors 110a, 110b may be buckles, hook and loop connectors, etc. that allow the free ends of the straps to connect to each other. The connectors 110a, 110b are larger than the gap 312 to prevent the straps 102a, 102b from being retracted away from their respective mounting devices 104a, 104b when the connectors 110a, 110b are not connected together. Likewise, the rear ends of the straps 102a, 102b are preferably larger than the gap 312 (e.g. the rings 108a, 108b) to prevent the straps 102a, 102b from being pulled from their respective mounting devices 104a, 104b, when the straps 102a, 102b are fully pulled into the forward or upward direction.
In the closed position, as best shown in FIG. 1, the free ends of the straps 102a, 102b are pulled upwardly around the pins 308, and over the top of the lid 4. Once the free ends are connected with the connectors 110a, 110b, the elastic members 106 pull on straps 102a, 102b over the lid 4 and place the straps 102a, 102b tightly over the lid 4. In that position, the lid 4 prevented from being lifted away from the main box 6 to open the container 2.
A user can place the closure device 100 into the open position by disconnecting the connectors 110a, 110b. When the free ends of the straps 102a, 102b are disconnected, the elastic members 106a, 106b retract the straps 102a, 102b away from the lid 4. Because the connectors 110a, 110b are larger than the gaps 312, the straps 102a, 102b cannot be pulled from the mounting devices 104a, 104b. When fully retracted, the connectors 110a, 110b preferably abut their respective mounting devices 104a, 104b. When the straps 102a, 102b are retracted, the lid 4 can be lifted away from the main box 6 to open the container 2.
Although certain presently preferred embodiments of the invention have been specifically described herein, it will be apparent to those skilled in the art to which the invention pertains that variations and modifications of the various embodiments shown and described herein may be made without departing from the spirit and scope of the invention.
