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 218 words
In a closure device of unitary resilient construction having first and second arms integral with and diverging from a hinge, together with latching structure for latching together said arms, the improvements comprising: a depending hook-shaped end portion on said first arm and provided with a first ledge portion in spaced relationship from and spanning the transverse dimension of said first arm and defining an adjacent recess extending the entire transverse dimension of said first arm, said second arm having an inner surface including an arcuate convex portion extending the entire transverse dimension of said second arm, said second arm having a projecting end portion projecting above the inner surface of said second arm, said projecting end portion having a triangular-shaped projection with one side of said triangular-shaped projection being exposed along a planar surface and forming an elongated planar sloped surface, another side of said triangular portion defining a second ledge portion, said projecting end portion being substantially entirely received in said recess of said first arm and substantially tightly fitting with said recess, with said ledge portions engaging each other thereby latching together said arms, and said second arm having the ends thereof pulled upwardly from a straightened configuration of said second arm and providing residual forces tending to return said second arm to said straightened configuration.
