Manthey teaches a support portion similar to Cox’s support 16 having straps 22 forming openings between grooves of support 16 and strap such that the tube passes through openings formed in the support portion. It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to have provided the device disclosed by Cox with support portion having openings formed by straps such that the tube passes through openings formed in the support portion as taught by Manthey in order to improve securing of tube on the support. Cox fails to disclose a plurality of fluidly independent parallel fluidic devices which are fluidically isolated from each other preventing mixing. Hecker, teaches a fluidic device 7-22 with reel which is part of plurality of fluidly independent parallel fluidic devices 7,8,11,25,24 which is fluidically isolated from other fluidic devices 8,25,24 to preventing mixing. It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to have provided the device disclosed by Cox with plurality of fluidly independent parallel fluidic devices which are fluidically isolated from each other preventing mixing as taught by Hecker in order to enable supplying multiple fluids. Cox as modified teaches multiple parallel independent fluid supply devices interconnected with each other in a horizontal direction (in view of Hecker) but fails to disclose plurality of fluid supply devices detachably interconnected with each other. Walther (Fig. 2) teaches a plurality of fluid supply device detachably (by removable fasteners 47) interconnected with each other in a horizontal direction (on horizontal bed of truck) and configured to individually supply a fluid It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to have provided the device disclosed Cox as modified with plurality of fluid supply devices detachably interconnected above as taught by Walther in order to enable disassembly. As to claim 17, the tube 19 is pulled out from the storage space by an external force, the support portion 27 is configured to move from an initial position of the support portion toward the outlet, and when the external force is released, the support portion is configured to move to the initial position by the restoring force of the position maintaining portion 31. As to claim 18, the position maintaining portion 30 is configured to apply the restoring force to the support portion through the gravity. As to claim 19, (in view of Walther the plurality of fluid supply devices each has) a fixing portion 28 positioned in the storage space and configured to support at least a portion of the tube at a different position from the support portion 27, and the fixing portion is configured to support the tube in a fixed position in the storage space. Response to Arguments Applicant’s amendment has overcome the rejection of record. However, a new ground of rejection is applied to the amended claims. Hecker is cited to show prior art teaching/incorporation of multiple fluidically independent non-mixing fluidic devices. Manthey is cited to show teaching of openings in support. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a).
