Abstract (en)
[origin: JPH01240452A] PURPOSE: To facilitate opening of a closure for a plastic bag and to provide the closure free from the leakage of liquid by comprising a first clamping leg with U-shaped cross-section, extending a side wall of the first clamping leg by a tongue part, determining the thickness of the tongue part less than that of the wall, providing a second clamping leg including a rib, with a V-shaped profile, and determining an opened internal width of the first clamping leg smaller than an external width of the second clamping leg. CONSTITUTION: A clamping leg 1 comprises the walls 5, 6 with U-shaped cross-section in parallel with each other and connected by a basic part. The tongue parts 9, 10 are lower than the walls 5, 6, and thinner than the same. A second clamping leg 2 comprises a V-shaped sectional profile, and two inclined walls 21, 21 are projected therefrom. To obtain the proper clamping action between the first clamping leg 1 and the second clamping leg 2, a distance of an opened internal width of the first clamping leg 1 is smaller than the external width of the second clamping leg 2. As a result, the tongue parts 9, 10 are bent outwardly when the V-shaped profile of the second clamping leg is engaged with a recessed part 16. The closure can be locked by a simple method in a state that it is clamped by the loosening means 26, 27, and the closure can be simply and easily opened only by slightly moving a lever 27.
