Abstract:
A wide faced applicator adapted to various kinds of fluid comprising a container tank, forming a threaded portion at its front edge; a main body, forming two spaced apart flange portions on its outer edge; a seat engaged with one of the flange portions on the outer edge of the main body to threadingly connect with the container tank; and a cover engaging with the front end of the main body, having a liner to insert onto the second of the two flange portions, wherein a flat cut face on opposite sides of a front axis portion of the main body forms a wide and narrow sided attachment face; a funnel shaped hole is formed at the axis center of the main body; a pin shaped core body is slidably received in the funnel shaped hole; a spring is engaged with a rear end edge of the core body; an end stopper has a bottom end which is tightly contacted against one end of the spring, an inner diameter hole of the end stopper is loosely engaged with the rear end of the pin shaped core body, and the outer edge of the core body is engaged with an axial end of the main body whereby a shoulder on a top end of the core body contacts tightly against the funnel shaped hole at a front axial end of the main body to form a locked shape; and a plurality of guiding holes are provided on the attachment face of the main body at its front end whereby the fluid in the container tank can be released by pressing an end of the core body adjacent the attachment face, and guided to permeate into the attachment face via the guiding holes, characterized in that the end of the pin shaped core body adjacent the attachment face is a plane with circular angles, the width of the guiding holes on the wide face side of the attachment face of the front axis portion of the main body is smaller or equal to the axial width of the end of the core body adjacent the attachment face, during an applying process, the guiding holes are flattened by the end of the core body adjacent the attachment face to produce a flat and even wide application face; and a plurality of throttling holes are provided on an end face of the end stopper and also on the peripheral edge, a proper gap is maintained between an inner face of the inner diameter hole in the end stopper and the rear end edge of the core body, so that by pressing the end of the core body adjacent the attachment face, an end of the inner diameter hole of the end stopper produces a pumping operation, and simultaneously when making a round movement at the end of the core body adjacent the attachment face, the fluid in the throttling holes on the end face of the end stopper and the peripheral edge pump out and in, or in and out, as a result of which the fluid in the main body is stirred up uniformly to easily flow to the guiding holes and continuously supply the need for the wide face application.
