Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
175 words
A latching arrangement for connectable panels comprising first and second panels, said first panel adapted to overlie a portion of said second panel in a latched position, said first panel having a leading edge and a first tongue extending therefrom beyond said leading edge, said first tongue including a first slot therein having a transversely extending longitudinal axis and a width, said second panel having an edge positioned beneath said first panel when said first panel is in overlying relationship with respect to said second panel and including a second tongue and a second slot, said second tongue being located wholly within said second panel and having a longitudinal extent directed away from said edge of said second panel, said second slot having a transversely extending longitudinal axis and a width, said transversely extending longitudinal axis of said second slot being generally perpendicular to the longitudinal extent of said second tongue, and said second slot spanning said second tongue and being positioned in said second panel wholly within the longitudinal extent of said second tongue.
Claim 2
Dependent Claim
175 words
A latching arrangement for connectable panels comprising first and second panels, said first panel adapted to overlie a portion of said second panel in a latched position, said first panel having a leading edge and a first tongue extending therefrom beyond said leading edge, said first tongue including a first slot therein having a transversely extending longitudinal axis and a width, said second panel having an edge positioned beneath said first panel when said first panel is in overlying relationship with respect to said second panel and including a second tongue and a second slot, said second tongue being located wholly within said second panel and having a longitudinal extent directed away from said edge of said second panel, said second slot having a transversely extending longitudinal axis and a width, said transversely extending longitudinal axis of said second slot being generally perpendicular to the longitudinal extent of said second tongue, and said second slot spanning said second tongue and being positioned in said second panel wholly within the longitudinal extent of said second tongue.
Claim 3
Dependent Claim
73 words
A latching arrangement for connectable panels as claimed in claim 1 wherein the length of said second slot is greater than the width of said first tongue, the width of said second slot is greater than the thickness of said first tongue, the length of said first slot is greater than the width of said second tongue and the width of said first slot is greater than the thickness of said second tongue.
Claim 4
Dependent Claim
53 words
A latching arrangement for connectable panels as claimed in claim 1 wherein said first slot includes an enlargement portion located intermediate the terminus of said first slot and said leading edge of said first panel thereby defining a first slot whose major width is substantially greater than the thickness of said second tongue.
Claim 5
Dependent Claim
48 words
A latching arrangement for connectable panels as claimed in claim 1 wherein the longitudinal distance between said first slot and said leading edge of said first panel is at least as great as the longitudinal distance between said second slot and the terminal edge of said second tongue.
Claim 6
Dependent Claim
57 words
A latching arrangement for connectable panels as claimed in claim 1 wherein at least said second panel is formed of a material having inherent resiliency whereby, upon insertion of said first tongue in said second slot, said second tongue will be capable of being deflected and returning to its original position substantially coplanar with said second panel.
Claim 7
Dependent Claim
39 words
A latching arrangement for connectable panels as claimed in claim 1 wherein at least a portion of the surface of said second tongue has applied thereto indicia which contrasts said portion with a surrounding portion of said second panel.
Claim 8
Dependent Claim
38 words
A latching arrangement for connectable panels as claimed in claim 1, wherein said first panel forms the movable cover of a book of matches and the second panel forms a fixed cover secured to the book of matches.
