Abstract
Abstract A container comprising a tubular body members of rectangular cross-section and a hinged lid member having a skirt formed by shallow depending walls adapted to telescope closely over the walls of the body member when the lid is in the closed position, is provided with latching means and a projection on the outside of each side wall of the body member adjacent the open end thereof having an interference fit with the inside surface of the side wall of the lid member, whereby compressive forces are exerted by the lid member on the side walls of the body member as the lid is closed, thereby causing the front wall of the body member to flex slightly to assure the positive engagement of the latching means.

Claim 9
Dependent Claim
217 words
In a container comprising a thin-walled, semi-rigid tubular body member of rectangular cross-section having a closed bottom portion, front and rear walls, and opposing side walls defining one open end, a shallow walled rectangular lid member having depending front, rear and opposing side walls adapted to telescope closely over the walls of the body member when in a closed position, and hinge means securing the rear wall of the lid member to the rear wall of the body member adjacent the open end thereof whereby said lid member is pivotable between open and closed positions, the improvement comprising lid latching means comprising a first pair of projections on the outside of the front wall of the body member adjacent the open edge thereof, a cooperating second pair of projections on the inside of the front wall of the lid member adjacent the lip thereof and adapted to engage said first pair of projections when said lid is in a closed position, and a projection on the outside of each side wall of the body member adjacent the open edge thereof having an interference fit with the inside surfaces of the side wall of the lid member in a closed position, whereby compressive forces are exerted by the lid member on the side walls of the body member.
Claim 10
Dependent Claim
