A dispensing closure construction of the type having a base part or body that is held captive on a container neck, and a sealing cap and integral hinge connected to the body. The body has an off-center discharge orifice and a high, domed top portion behind the orifice and extending above the level thereof so as to channel product from the top portion back toward the orifice after the container is used and returned to an upright position. A continuous sealing shoulder on the body engages the inner cylindrical surface of the sealing cap near its edge when the latter is swung to its closed position to minimize the possibility of water or other liquid from entering the area around the underside of the cap. A rib carried on the underside of the sealing cap is receivable in a recess in the domed top portion, and can engage opposed, facing shoulders so as to limit relative turning between the cap and body. The rib and recess are adjacent the location of the hinge. This construction has the desired effect of reducing the likelihood of damage to the hinge if torque, from automatic capping equipment, is applied to the cap; such damage might otherwise occur where the capping equipment is arranged to drive the cap itself as opposed to conventional arrangements where the drive torque is applied to the body. The offset dispensing orifice is sealed by a depending sealing peg on the cap. The off-center location of the peg and orifice also operate to limit relative turning between the cap and body, and provide added protection against inadvertent stretching or breakage of the hinge. |
