<p>A dispensing cap for a container. The cap has a tubular body of circular transverse cross-section with a wall closing the top end of the tubular body. An upwardly opening slot is formed in the top end wall and extends across the tubular body with a generally flat wall forming the bottom of the slot. An aperture extends through the bottom of the slot into the tubular body. A hinge assembly is located in the slot and includes an upstanding member formed on the flat bottom wall of the slot at a location inwardly of the circular perimeter of the tubular body. A flap is integrally connected to the upstanding member of the hinge assembly by a strap. A portion of reduced thickness is formed in the strap to create a hinge at the juncture of the strap and the upstanding member. The portion of reduced thickness of the strap is formed by an inclined slot cut in the tubular body near the top end wall and extending into the upstanding member. Inclined ramp surfaces are formed at opposite ends of the upstanding member and corresponding aligned projections are formed on the flap. The projections engage the ramp surfaces during a selected arc of travel of the flap to retard the flap in that position.</p> |
