The tool also includes a hook at the first end to engage holes in tabs of a first container to release a lid of the container. The tool further includes a splayed member at the second end having a gap to engage and re-seal the lid onto the container, a cut block to provide a fulcrum on which to leverage the body, and a leverage block to provide a fulcrum on which to leverage the body. The tool also includes a blade coupled to the body to operate in concert with the cut block to cut a lid of a second container to create tabs on the lid and a pry member mounted on the body configured to operate in concert with the leverage block to pry the tabs of the second container lids to release the lid of the second container.




According to another embodiment of the present invention, a tool for opening and re-sealing containers is provided. The tool includes a body, a hook, a blade, a pry member, and a splayed member having a gap, a first block, and a second block.




According to yet another embodiment of the present invention, a tool for opening and re-sealing containers is provided. The tool includes a first end having a hook and a second end having a splayed member having a gap.




According to another embodiment of the present invention, a tool for sealing containers is provided. The tool includes a body and a gap defined in the body, the gap being configured to engage a lid to seal the lid onto a container.




According to another embodiment of the present invention, a tool for opening containers is provided. The tool includes a body having a first side and a second side. The tool also includes a block connected to the body extending from the first side and a blade extending from the body wherein the body extends tangentially relative to a container during use of the blade.

of bucket


50


. Further, bending the tabs


58


upwards widens the annular groove of rim


56


such that the groove does not snugly engage the upper edge of container portion


52


.




Tool


10


is used to open bucket


50


by inserting tip


22


of hook


20


into hole


60

58


. After all tabs


58


, or at least a significant portion of tabs


58


, are bent upwards in this manner, lid


54


may be removed.




When bucket


50


needs to be closed and re-sealed, gaps


30


,


32


,


34


of splayed member


28


are used as shown in FIG.


3


. Each of gaps


30


,


32


,


34


are of different sizes, and correspond to a standard width or thickness of a bucket rim


56


. Depending on the size of rim


56


of a particular lid


54


, the proper gap


30


,


32


,


34


is used to bend tabs


58


back into contact with container portion


52


of bucket


50


and to decrease the width of the annular groove as shown in FIG.


3


. To bend tabs


58


down, a side of gap


30


,


32


,


34


is placed on an interior side of rim


56


. First end


12


of tool


10


is then moved such that gap


30


,


32


,


34


contacts an exterior side of rim


56


and tab


58


. Leverage is then applied downwardly, as viewed in

FIG. 3

, at first end


12


of tool


10


to rotate tabs


58


back into contact with container portion


52


of bucket


50


and to decrease the width of the annular groove, thereby re-sealing bucket


50


.




A plastic bucket


100


, as shown in

FIGS. 4 and 5

, also has a container portion


102


and a lid


104


. Lid


104

106


and container portion


102


includes a corresponding rim or upper edge


103


shown in FIG.


5


. Rim


106


of lid


104


fits onto upper edge


103


of container portion


102


such that lid


104


is coupled to container portion


102


to provide a perimeter seal along upper edge


103


of container portion


102


. When plastic bucket


100


is first encountered, rim


106


of lid


104


is a substantially solid ring. In order to remove lid


104


, rim


106


is cut into tabs


108


. To cut rim


106


into tabs


108


, tool


10


is placed against lid


104


as shown in

FIG. 4

such that cut block


37


(not shown in

FIG. 4

) is on top of rim


106


, top


16


of tool


10


is facing upwards, first side


15


of tool


10


is facing lid


104


, and blade


48


is below rim


106


. First end


12


of tool


10


is then raised upwards as a lever utilizing cut block


37


as a fulcrum such that edge


72


of blade


48


engages rim


106


and makes a cut therein. Tabs


108


are created by repeating this operation, making cuts at spaced apart locations about the perimeter of rim


106


.




Once tabs


108


are created, tabs


108


are disengaged from rim


106


of container portion


102


of bucket


100


. To this end, leverage block


36


is placed on top of lid


104


on the interior side of rim


106


as shown in FIG.


5


. Pry wedge


38


is placed below a tab


108


and then raised such that edge


47


of wedge


38


is placed between tab


108


and container portion


102


. As first end


12


of tool


10


is further raised, pry wedge


38


pulls tab


108


outward and upward from container portion


102


of bucket


100


, disengaging a portion of rim


106


from upper edge


103


. After all tabs


108


, or at least a significant portion of tabs


108


, have been pulled up, lid


104


may be removed from container portion


102


. Bucket


100


may be re-sealed by placing lid


104


on the container portion


102


and applying downward pressure such that rim


106


of lid


104


snaps onto or reengages upper edge


103


to secure lid


104


to container portion


102


.
