[0066] The free end 54 of the third wall 55 of the lower portion 51 of the cap 31 is substantially planar so that the lower portion of the cap can positioned on a substantially planar surface 93 of a support 91, such as a table or floor, as shown in FIG. 18. The first receiving area 48 is easily accessible by the electrician so that there is no need for the electrician to hold the needed electrical connectors in his hand or mouth.
[006'7] Alternatively, the cap 31 can be positioned such that the second receiving area 56 is readily accessible, as shown in FIG. 19. The free end 44 of the second wall 45 of the upper portion 41 of the cap 31 is substantially planar so that the upper portion of the cap can positioned on the substantially planar surface 93 of the support 91, such as a table or floor, as shown in FIG. 19. The second receiving area 56 is easily accessible by the electrician so that there is no need for the electrician to hold the needed electrical connectors in his hand or mouth.
[0068] When the electrician's work has been completed, the unused electrical connectors 95 can be returned to the jar cavity 23. The cap 31 is then connected to the jar 21 to close the storage container 11, which can be hung on a hook 81 as shown in FIG. 17 for storage.
[0069] A storage container 111 in accordance with another exemplary embodiment is shown in FIGS. 21 ¨ 33. The storage container 111 is substantially similar to the storage container 11 of the exemplary embodiment shown in FIGS.
1 ¨
19. Accordingly, similar features will not be described with regard to the exemplary embodiment of FIGS. 21 ¨33 and are referred to with a reference numeral in the "lxx" series.
[0070] The jar 121 has a cavity 123 defined by a base 125 and a wall 127 extending upwardly from the first base, as shown in FIGS. 21 and 29 ¨ 33. The base 125 of the jar 121 is preferably circular, as shown in FIGS. 29 and 33. The wall 127 has a reduced diameter portion 122, as shown in FIGS. 21 and 30 ¨ 32, thereby forming a shoulder 124. An alignment indicator 171 is disposed on an outer surface 128 of the wall 127 of the jar 121, and is preferably disposed on the reduced diameter portion 122 adjacent a free end 172 of the wall 127. As shown in FIGS. 21 and 30, the alignment indicator 171 is an outwardly extending tab having a substantially pentagonal shape. Preferably, a pair of alignment indicators 171 are diametrically opposed on the outer surface 128 of the reduced diameter portion 122 of the wall 127, as shown in FIG. 31. A textured band 180 can extend circumferentially around the outer surface 128 of the wall 127 of the jar 121 to facilitate aligning a label affixed to the outer surface 128 of the jar 121. The jar 121 is preferably made of polypropylene and is transparent.
[0071] First and second cap position indicators 173 and 174 are disposed on the outer surface 128 of the wall 127, as shown in FIGS. 21, 30 and 31, to indicate whether the container 111 is in an unlocked or locked position. Preferably, the first cap position indicator or unlocked indicator 173 is vertically aligned with the alignment indicator 171, as shown in FIGS. 21 and 30. A substantially circular indicator 173, such as a "0", indicates the container 111 is in an unlocked position. A
substantially vertical indicator 174, such as a I", indicates the container 111 is in a locked position. Preferably, the second cap position indicator or locked indicator 174 is vertically aligned with the protrusion or detent 126. Preferably, a pair of unlocked indicators 173 and a pair of locked indicators 174 are diametrically opposed, respectively, on the outer surface 128 of the jar 121. Accordingly, the indicators 173 and 174 alternate around the circumference of the jar 121 at approximately 90 degree intervals.

[0072] The base 125, as shown in FIG. 33, has a recessed portion 175. The recessed portion 175 of the base 125 can include descriptors, such as a recycling symbol 176, a time and date stamp 177 and a mold cavity number 178.
[0073] The cap 131 is removably connectable to the jar 121, as shown in FIG.
21.
The cap 131 has an upper portion 141 connected to a lower portion 151 by a connecting member 161, as shown in FIGS. 21 ¨ 23 and 25 ¨27. Preferably, the cap 131 is made of polypropylene and is transparent. Additionally, the cap 131 can be colored, such as red, yellow, blue or gray.
[0074] A stacking member 181 extends upwardly from an inner surface 146 of a base 143 of the upper portion 141, as shown in FIGS. 21 and 23 ¨ 27, to facilitate stacking assembled containers. The stacking member 181 can have any suitable shape, such as a company logo. Accordingly, a width 184 (FIG. 25) of the stacking member 181 substantially corresponds to a width 179 (FIG. 32) of the recessed portion 175 of the base 125 of the jar 121 such that a frictional fit secures the cap 131 of a first container 111 in the recessed portion 175 of the base 125 of the jar 121 of a second container 111. Additionally, the cap 131 can be connected to the base 125 of the jar 121 when accessing contents stored in the container 111 such that the cap 131 is not lost when disconnected from jar 121.
[0075] An outer surface 182 of a wall 155 of the lower portion 151 has an alignment indicator 183. Preferably, a pair of alignment indicators 183 are diametrically opposed on the outer surface 182 of the wall 155 of the lower portion 151.
[0076] An inner surface 157 of the lower portion 151 has a corresponding detent or recess 158, as shown in FIG. 27, to receive the corresponding detent or recess 126 of the jar 121 when connecting the cap 131 to the jar 121. An alignment guide 191 is formed on the inner surface 157 of the lower portion 151 of the cap 131, as shown in FIGS. 27 and 28. Preferably, a pair of alignment guides 191 are diametrically opposed on the inner surface 157, as shown in FIG. 28. The alignment guide 191 includes first and circumferentially extending ribs 192 and 193. Axially extending ribs 194 and 195 extend axially from the circumferentially extending ribs 192 and 193 toward a free end 154 of the wall 155 of the lower portion 151. An opening 196 is formed between the axially extending ribs 192 and 193 to receive the alignment indicator 171 of the jar 121. The free ends of the axially extending ribs 192 and 193 are preferably tapered inwardly, as shown in FIG. 27, to facilitate receiving the alignment indicator 171. The opening 196 is aligned with the cap alignment indicator [0077] To connect the cap 131 to the jar 121, the cap 131 is positioned with respect to the jar 121 such that the alignment indicator 183 of the cap 131 is aligned with the alignment indicator 171 of the jar 121. Aligning the indicators 183 and 171 facilitate orienting the cap 131 with respect to the jar 121 during installation. The alignment indicator 171 of the jar 121 is received in the opening 196 in the alignment guide 191 of the cap 131, thereby substantially preventing misalignment of the cap 131 with respect to the jar 121 during installation. Additionally, the cap 131 is prevented from being connected to the jar 121 when the alignment indicators 171 and 183 are not aligned because the alignment indicator 171 abuts one of the circumferentially extending ribs 192 or 193 to prevent the cap 131 from being pushed onto the jar 121.
[0078] The cap 131 is pushed onto the jar 121 until the free end 154 of the lower portion 151 abuts the shoulder 124 of the jar 121, as shown in FIG. 1. The alignment indicator 183 of the cap 131 points toward the unlocked indicator 173 of the container 121, thereby indicating that the cap 131 is in the unlocked position. The cap 131 is then rotated approximately a quarter turn, as in the exemplary embodiment of FIGS. 1 ¨ 19, such that the detent or recess 126 of the jar 121 is received by the corresponding recess or detent 158 of the cap 131, thereby securing the cap 131 to the jar 121. The alignment indicator 183 of the cap 131 now points toward the locked indicator 174 of the jar 121, thereby indicating that the cap 131 is in the locked position.
[0079] The installation procedure is reversed to remove the cap 131 from the jar 121. The cap is rotated approximately a quarter turn such that the alignment indicator 183 of the cap 131 is aligned with the first cap position indicator 173, thereby indicating that the cap 131 is not locked to the jar 121 and can be removed.

[0080] While advantageous embodiments have been chosen to illustrate the invention, it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the scope of the invention as defined in the appended claims.
