So, in essence, the upper cover 103 may be opened and closed by the touch and push of the hand of a user.

An inner cover 116 is arranged in an outer frame 119 as seen in FIGS. 1, 10, and 13. The outer frame 119 is position upon the inner rim 160 (FIG. 10) of the locating snap ring 113 so that the inner rim 160 supports the outer frame 119. The outer frame 119 includes a pair of hooks 162 that engage the underside of the locating snap ring 113 to removably attach the outer frame 119 to the locating snap ring 113. Referring to FIG. 13, a pivot pin 164 is journaled through bearings 166 attached to the underside of the rear end of the outer frame 119. The pivot pin 164 also extends through a torsion springs 168. The leg 170 of each torsion spring 168 engages the underside of the inner cover 116 and is press fitted between two support plates 172 attached to the inner cover 116 to secure the leg 170 to the inner cover 116. The torsion springs 168 bias or urge the inner cover 116 against the outer frame 119 in the closed position (FIG. 11) to further seal the trash inlet and prevent an odor from leaking. The inner cover 116 may pivot downwardly away from the outer frame by a force (e.g. a user pushing the inner cover with his or her hand) that is sufficient to overcome the biasing force of the torsion springs 168. In this open position (FIG. 12), the trash inlet is opened so that trash items may be placed in the trash bag. Once the downward force is released from the inner cover 116, the biasing force of the torsion springs 168 moves the inner cover 116 against the outer frame 119 in the closed position.

A locking knob 117 for locking the inner cover 116 is arranged in the outer frame 119 to lock the inner cover 116 to the outer frame 119 in the closed position by rotating knob 174 of the locking knob 117. In particular, the locking knob 117 may be in the form of a cam lock and includes a cam or arm 176 and the knob 174. In the locked position, the arm 176 engages the underside of the inner cover 116 to prevent the inner cover 116 from pivoting down. Rotation of the knob 174 ninety degrees rotates and moves the arm 176 away from the inner cover 116 to the position shown in the phantom lines of FIG. 13. In this unlocked position, the inner cover 116 may be pivoted downward to open the trash inlet of the trash can.

A pair of parallel rails 178 are attached to the underside of the inner cover 116. Each rail includes a hook flange 180 that extends inwardly toward the other rail. A freshener housing 182 is provided in the trash can. The freshener housing 182 houses a freshener for masking or reducing the odors in the trash container. The freshener housing 182 includes a bottom wall 184 that has a plurality of opening or perforations to allow the emission of the fresh odor from the freshener in the freshener housing 182. The freshener housing 182 also includes a pair of outer flanges 186 (FIG. 10) that extend outwardly from the top end of the freshener housing 182. The freshener housing 182 may be removably mounted to the underside of the inner cover 116. This is accomplished by having the hook flanges 180 slidably receive the respective outer flanges 186 of the freshener housing 182 with the outer flanges 186 positioned upon the hook flanges 180. The freshener housing 182 may be removed from the inner cover by sliding the freshener housing off of the rails. Once removed, a user can replace the freshener in the housing with a new freshener and then slide the freshener housing back on the rails 178.

As seen in FIG. 9, the trash can is provided with a base 118. The lower-section can body 102 is fixed on the base 118. A door body 107 is pivotally connected to the lower-section can body 102 and may engage the lower-section can body by magnetic force. In particular, a first magnet 188 is press fitted or otherwise securely received into a lower pocket 190 at the side edge of the door body 107. A second magnet 196 is secured to a lower portion at the side edge of the lower-section can body 102 opposite the door body 117. A third magnet 198 is secured to an upper portion of the lower-section can body 102 at the side edge opposite the door body 107. A fourth magnet 192 is press fitted or otherwise securely received into an upper pocket 194 at the side edge of the door body 107. When the door body 107 closes, the first magnet 188 magnetically engages the second magnet 196 and the third magnet 198 magnetically engages the fourth magnet 192.

FIGS. 14 to 16 show another embodiment of the present invention. This embodiment is similar to that shown in FIGS. 8 to 13, except as discussed below. In this embodiment elements that are similar in function with the embodiment of FIGS. 8-13 will be given the same reference numbers. In this embodiment, inner cover 216 of trash can 200 is attached to the upper cover 103 such that the inner cover 216 opens and closes as the upper cover 103 opens and closes. In particular, as illustrated in FIG. 15, the inner cover 216 includes a first T-shaped tab 230 on the top side of the inner cover 216. The upper cover includes a second T-shaped tab 232 on the underside of the upper cover 103. A looped elastic band 234 such as a rubber band is looped around the first and second tabs 230, 232 to attach them to each other. The inner cover 216 is pivotally connected to outer frame 219, which is positioned upon the inner rim of the locating snap ring 113. Thus, as the upper cover 103 pivots upwardly on the rear end of the can and opens, the elastic band 234 tensions and causes the inner cover 216 to also pivot upwardly and open. In this opened position, the trash inlet is opened. Likewise, as the upper cover 103 pivots downwardly on the rear end of the can and closes, the elastic band 234 relaxes and the inner cover 216 also pivots downwardly and closes. In this closed position, the trash inlet is closed.
