Abstract
Abstract Tube closure devices comprising bendable members, each having a pair of arms connected together by integral hinges are disclosed. Coacting latch arrangements are disposed on the extending ends of the arms to latch the arms over sections of flexible tubes which are placed under compression via the closure devices. Raised floor sections on at least one of the arms serve to compress and sealingly close the tube such that residual pressures are provided in a closure. Alternate curved floor sections also assure a sealed closure and provide strain relief means in a closure where the flexible tubes join closure devices.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
179 words
A pair of generally V-shaped, reusable metal closure devices for closing and sealing a flexible tube comprising first arms and second arms, integral hinges at inner ends of said arms connecting said arms together, a bridge connecting said pair of devices together, said bridge positioned between two of the arms of the devices, each of said devices adapted to close onto and flatten and seal sections of the tube, each of said first arms having a tab on an outer end thereof, said tab being of less width than said first arm, a recess in each outer end of said second arms, said recesses adapted to receive said tabs when said arms are closed on the sections of the tube, said tabs further adapted to be bent under portions of said second arms to latch the arms into closed engagement onto the sections of the tube, said arms each having a centrally disposed, inwardly directed ridge on the inside surface thereof so that as said arms are closed, said ridges cooperate to tightly and sealingly engage the tube thereinbetween.
