ABSTRACT:
This imbiber is to be used, for instance, by dentists for imbibing with a treating liquid a cotton swab held by a cotton plier. The treating liquid is contained in a container having at its upper end a pumping assembly including a piston having an upright piston rod terminated at its top end with an enlarged head formed with a top recess, into which opens a bore formed in the piston and piston rod and communicating with the cylinder of the pump assembly. This cylinder is located within the neck of the container and has at its lower end an intake tube extending close to the bottom of the container. A check valve is mounted in the lower end of the cylinder and a biasing spring urges the piston rod to an upper limit position. By applying with a cotton plier a cotton slab within the recess and depressing the piston with the pliers, the cotton swab becomes soaked with the treating liquid, this being done in a single operation.
