초록

An aperture formed through a spring member increases the size of the angle of inclination which the spring member assumes relative to a vertical side wall of a dispenser box. The spring member is utilized in a box closure for opening and closing the box.

A closure for a dispenser box having a box wall formed with a discharge opening lying in a plane, said closure comprising: (a) an elongated spring member having opposite end portions and an intermediate portion between the end portions, (b) said spring member being tensioned by a longitudinal bend extending lengthwise along the elongation of the spring member, (c) one of the end portions being stationarily mounted on the box wall, (d) the other of the end portions being movable relative to the box wall, in response to manual pressure exerted on the intermediate portion in a direction generally normal to the longitudinal bend to reverse the longitudinal bend at the intermediate portion to form a transverse bend extending widthwise across the elongation of the spring member, from (i) a closed position in which the other end portion overlies and closes the discharge opening, to (ii) an open position in which the other end portion extends outwardly at a predetermined angle of inclination relative to the plane of the discharge opening, (e) said intermediate portion having an opening which extends through the spring member and which increases the angular magnitude of said angle of inclination than that which would exist if the opening were not present, (f) said other end portion being returnable from the open position to the closed position in response to manual pressure exerted on the other end portion in said normal direction to reverse the transverse bend and form the longitudinal bend again at the intermediate portion, and (g) said other end portion being resiliently maintained under tension by the longitudinal and transverse bends in the closed and open positions respectively.
