Abstract:
1. An applicator for dispensing a medicinal substance therethrough, where the substance has a cream-like consistency of the type which does not flow easily without a force being applied thereto, which comprises: a body having an external surface, formed about an axis which extends from a proximal end of the body to an exterior axial surface of a closed distal end of the body; the body formed with a proximal section which extends from the proximal end of the body toward the closed distal end of the body, and to a distal end of the proximal section; the proximal section of the body formed with an axial entry passage extending through the proximal section from the proximal end of the body toward the closed distal end of the body, and to a distal end of the axial entry passage; the axial entry passage being formed with a prescribed diameter at the proximal end of the body; the body being formed with an axial intermediate passage having a proximal end in communication with the distal end of the axial entry passage, and extending toward the closed distal end of the body, and to a distal end of the axial intermediate passage; the axial intermediate passage being formed with a uniform passage diameter which is less than the prescribed diameter; the body being formed about the axis thereof with a passage section, having a uniform exterior diameter, which extends from a proximal end thereof toward the closed distal end of the body, and to a distal end of the passage section; the body formed with a flange section having a proximal end formed integrally with the distal end of the proximal section, and a distal end formed integrally with the proximal end of the passage section of the body; a flange located in the flange section of the body and extending radially outward from the external surface of the body to an outer edge surface of the flange; the passage section of the body fully surrounding at least a portion of the axial intermediate passage to the distal end of the axial intermediate passage; the body being formed about the axis thereof with a slot section, having the uniform exterior diameter, which extends from a proximal end of the slot section toward the closed distal end of the body, and to a distal end of the slot section, with the proximal end thereof being formed integrally with the distal end of the passage section; a slot delivery passage formed axially through the slot section of the body from a proximal end thereof toward the closed distal end of the body, and to a closed distal end of the slot delivery passage, with the proximal end of the slot delivery passage being in communication with the distal end of the axial intermediate passage; at least one axially-elongated slot formed radially through the slot section of the body in unobstructed communication with the slot delivery passage and an exterior of the body, and extending from the proximal end of the slot section toward the distal end of the slot section, and to a distal end of each of the at least one axially-elongated slot; the slot delivery passage being formed with the uniform passage diameter interrupted only by the presence of the at least one axially-elongated slot; the body formed with a solid section, having the uniform exterior diameter, which extends from a closed proximal end of the solid section toward the closed distal end of the body, and to a closed distal end of the solid section, with the closed proximal end of the solid section being formed integrally with the distal end of the slot section; the body formed with a dome section in the form of a solid dome, which extends from a closed proximal end of the dome section to a closed distal end of the dome section, which is coincidental with the exterior axial surface of the closed distal end of the body; the closed proximal end of the dome section being formed integrally with the closed distal end of the solid section; and the solid section and the dome section being exclusive of any opening.
