Abstract
A closure of synthetic resin material has a cap connected to a base which fits onto the container by a hinge joint which may be of the flexible film type and can be molded unitarily with the base and cap. On the opposite side of the cap from the hinge, there is provided a lever which has a pressing plate and a hook, the latter being engageable with a detent on the base so that entered pressure on the plate allows the cap to swing upwardly.
Claims30
A closure by synthetic-resin material for rigid or deformable containers having a base mountable on said container with at least one discharge opening;
- and a cap with a seal connected to said base by a hinge joint provided with at least one lever-type projection, said lever type projection being articulated to said cap and having at least one pressing plate, at least one hook-shaped formation and at least one detent pin on the base.
A method for actuating a closure for a container, said closure being connected to said container by a base whose cap is openable by swinging it about a hinge joint, according to which method first a pressing force is applied in a direction perpendicular to the closure axis, releasing a latch, and then by maintaining this force, pressure is applied in the direction of the closure axis, whereby, at least in the initial period of the opening process both forces, the one applied perpendicularly to the closure axis and the one applied parallelly to the axis, acting simultaneously a force being applied to the cap of the closure in the direction of an arrow, pressing the cap against the base and deforming a resilient member, thereby releasing the self-locking arrangement of the latch, and wherein by applying a force perpendicular to the closure axis immediately thereafter, the latch is released and the closure is opened.
