摘要:
One applicator for use with ointment includes a housing defining a holding chamber. The holding chamber has a single entrance distinct from a single exit and is flexible such that deformation of the housing reduces capacity of the holding chamber and forces contents of the holding chamber to pass through the exit. A one-way valve is at the entrance for allowing the ointment to enter the holding chamber through the entrance and restricting the ointment from exiting the holding chamber through the entrance. A tip extends from the housing adjacent the exit. The tip has a proximal end meeting the housing and a pliant distal end spaced apart from the housing. The tip distal end is flared from the tip proximal end and has a generally planar leading surface. A channel in the tip extends from the exit to the leading surface, and is flared at the leading surface.
