Abstract
A lid opening mechanism in which a lid can be opened and closed on a hinge with respect to an associated body 1, includes two slits formed in an arbitrary part of the hinge 3 so as to extend along the opening/closing dimension of the hinge 3 and spaced apart from each other so as to define therebetween a pushing operation section that is large enough to be pushed with a finger, wherein the slits extend across hinge grooves of the hinge, with at least one end of each slit reaching the body or the lid, whereby it is possible for the lid of various cases, containers, etc. or the opening member of various apparatuses to be opened to a desired angle with one hand and by a one-push operation.
Claims20
A lid opening mechanism system comprising a container having a body structure and a lid structure, a side section integral with said body structure and said lid structure and extending in a generally longitudinal direction, two spaced slits in said side section extending transversely of said longitudinal direction, the portion of the side section between said two spaced slits forming a push-in part, the width of said push-in part in said longitudinal direction being at least as great as the width of a person's finger, the parts of the side section on either side of said push-in part forming aligned lateral parts, said lateral parts including a flexible hinge which flexes as one of said structures is moved relative to the other of said structures from a closed position to an open position, said push-in part being operable to be pushed in by a person's finger to move said push-in part from a non-pushed-in position to a pushed-in position, said push-in part in being moved from said non-pushed-in position to said pushed-in position effecting movement of said one structure relative to said other structure about said flexible hinge from said closed position to said open position, said push-in part when in said non-pushed-in position being in general alignment with said lateral parts and having substantially the same configuration as said lateral parts to thereby form a continuation of said lateral parts.
A lid opening mechanism system comprising a container having a body structure and a lid structure, a side section integral with said body structure and said lid structure and extending in a generally longitudinal direction, two spaced slits in said side section extending transversely of said longitudinal direction, the portion of the side section between said two spaced slits forming a push-in part, the width of said push-in part in said longitudinal direction being at least as great as the width of a person's finger, the parts of the side section on either side of said push-in part forming aligned lateral parts, said lateral parts including a flexible hinge which flexes as one of said structures is moved relative to the other of said structures from a closed position to an open position, said push-in part being operable to be pushed in by a person's finger to move said push-in part from a non-pushed-in position to a pushed-in position, said push-in part in being moved from said non-pushed-in position to said pushed-in position effecting movement of said one structure relative to said other structure about said flexible hinge from said closed position to said open position, a hook device having one hook part disposed on said one structure and another hook part disposed on said other structure, said one and said other hook parts being movable between a hooked position and a release position, said one hook part being movable from said hooked position by pushing on one of said structures juxtaposed to one of said hook parts with one or more fingers of a person's hands while said pushed-in part is moved from said non-pushed-in position to said pushed-in position by other fingers of the same hand of said person, whereby said hook device is moved from its hooked position to its release position and said one structure is moved from said closed position to said open position by the fingers of one hand of said person.
