Referring now to FIGS. 2-4, one embodiment of an interchangeable utility module 100 is shown as a food preservation cartridge 120. The cartridge 120 has a housing 126 that receives a pair of sachets 122, 124. Each of the sachets 122, 124 contains an ethylene absorbing agent to eliminate ethylene generated by food items stored in the drawer 62. One example of an ethylene absorbing agent is described in U.S. Pat. No. 5,278,112 entitled “CHEMICALLY IMPREGNATED ZEOLITE AND METHOD FOR CHEMICALLY IMPREGNATING AND COATING ZEOLITE,” which is incorporated in its entirety herein by reference.
The housing 126 of the cartridge 120 has a number of sidewalls 128 extending upwardly from a bottom wall 130 to an upper end 132. A cover 134 is hinged to the upper end 132 of the housing 126. The sidewalls 128 define a pair of rectangular compartments 136, 138, each of which is sized to receive one of the sachets 122, 124. An open top side 140 of the housing 126 defines access openings 142, 144, which provide user access to the sachets 122, 124 when the cover 134 is open. When the cover 134 is closed, the access openings 142, 144 are sealed, thereby preventing the user from accessing the compartments 136, 138 and the sachets 122, 124 positioned therein.
One of the sidewalls 128 includes a plurality of vent openings 146 that permit air to pass into and out of the compartments 136, 138. In that way, ethylene generated within the drawer 62 advances into the compartments 136, 138. Within the compartments 136, 138, ethylene reacts with the ethylene absorbing agents contained in the sachets 122, 124, thereby helping to preserve food items stored in the drawer 62. It will be appreciated that in other embodiments other sidewalls 128 and/or the bottom wall 130 of the housing 126 may include vent openings that permit air to pass into and out of the compartments 136, 138.
The cover 134 of the cartridge 120 includes an outwardly extending flange 150 that may be used to open the cover 134. As shown in FIGS. 3 and 4, the cover 134 also includes a plate 152 extending upwardly to a top surface 154. The plate 152 has a slot 156 defined in an end 158. The slot 156 is sized to receive an elapsed time indicator 160, which provides an indication of how long the sachets 122, 124 have been in use. When the sachets 122, 124 are replaced, a new indicator 160 is placed in the slot 156. The indicator 160 includes a status bar 162 that displays the amount of time elapsed since the sachets 122, 124 were placed in the cartridge 120. When the indicator 160 is properly positioned in the slot 156, the status bar 162 is visible through an aperture 164 formed in the top surface 154 of the plate 152. One example of an elapsed time indicator is the Timestrip®, which is commercially available from Timestrip Plc. of England, U.K.
The top surface 154 of the plate 152 also includes label zones 166, 168 that inform the user of which interchangeable utility module is currently in use. As shown in FIGS. 3 and 4, the food preservation cartridge 120 has the text “FRESH FLOW” formed in the label zones 166, 168, indicating that the current interchangeable utility module 100 is the food preservation cartridge 120. Other interchangeable utility modules 100 may include similar markings to indicate which interchangeable utility module is currently in use. It will also be appreciated that in other embodiments graphics or other images may be used in the place of text to inform the user of which interchangeable utility module is currently in use.
