Bag closure clamp with hinge-supplementing complementary cam surfaces

Abstract

A bag closure for sealing bags. The closure comprises a sheath having a trough which matingly engages a blade-like body of a wedge-shaped member. A roof portion of the sheath is dimensioned so as to be permitted to carry intelligible indicia thereon. An upper edge of the blade-like body is provided with a designated location for receiving a bag. The blade-like body slightly smaller in width than the trough, enabling the closure to clamp the bag tightly therein. A hinge strap which pivotally connects the sheath and the wedge-shaped member is dimensioned to be durable and to ensure that the blade-like body remains in proper alignment with the trough. A latch retains the closure in a closed position. In the closed position, a tip of the latch forms a protuberance is easily displaced to enable the closure to be easily opened. A safety lock ensures that the blade-like body properly aligns with the trough, relieves the stress from the hinge strap, and ensures that the closure does not inadvertently open upon breakage of the hinge strap. With the closure closed, the safety lock is concealed within the trough where it remains unobtrusive. In use, the neck of a bag is folded about the designated location of the blade-like body and, upon closing the closure, the neck of the bag becomes tightly clamped within the trough, sealing the bag against leakage.
