ABSTRACT:
A device for closing and sealing bags which eliminates the tightening of the mouth, and makes the operation simple, rapid and safe. The device, according to the invention, comprises a flat housing with an open bottom which receives the folded mouth (preferably two series of folds reminiscent of an accordion) of a bag. An element is extended between the two larger sides of the housing, passing through aligned orifices in the folded mouth of the bag. This effects immobilization between the element and the two larger sides. In the preferred embodiment, the element is, in reality, two lengths of cord fixed to one of the larger sides and freely passing across the other. In this case, the larger sides form part of two halves of the housing, which are separable for opening the bag. In the closed position, the two halves can be locked and sealed.
