- ABSTRACT A device adapted to dispense reagents comprising an.
- outer tubular member having an open end and a second end comprising an end wall having therein a concentric circular opening, a vial received in the open end of said tubular member having a resilient stopper sealing its open end, said stopper having an annular shoulder thereon to prevent reciprocation of said stopper in said vial, said stopper also having a projection thereon which is concentric with the stopper, a fluid passage through said stopper and projection, said projection extending through said concentric circular opening and beyond said end wall of the tubular member, said projection having an externally raised ring which forms a snap-fit on the exterior of the concentric circular opening to restrain the projection against longitudinal movement within the opening, said stopper also having an internally hollow convex dome-like configuration in proximity to the inner end of said projection and extending beyond the end of said vial which is adapted to be compressed when said vial is fully advanced within said tubular member to expel a drop of fluid from said vial through said fluid passage.
- this invention comprises a device adapted to dispense reagents comprising an outer tubular member having an open end and a second end comprising an end wall having therein a concentric circular opening, a vial received in the open end of said tubular member having a resilient stopper sealing its open end, said stopper having an annularshoulder thereon to prevent reciprocation of said stopper in said vial, said stopper also having a projection thereon which is concentric with the stopper, a fluid passage through said stopper and projection, said projection extending through said concentric circular opening and beyond said end wall of the tubular member, said projection having an externally raised ring which forms a snap-fit on the exterior of the concentric circular opening to restrain the projection against longitudinal movement within the opening, said stopper also having an internally hollow convex dome-like configuration in proximity to the inner end of said projection and extending beyond the end of said vial which is adapted to be compressed when said vial is fully advanced within said tubular member to expel a drop
- a further object of this invention is to provide a dropper particularly adapted to the application of a reagent to the surface of the skin.
- FIG. 1 is an exploded side view of the device of this invention.
- FIG. 2 is a sectional view of the two uppermost parts shown in FIG. 1.
- FIG. 3 is a sectional view of the two lower parts shown in FIG. 1.
- FIG. 4 is a sectional view of the device of this invention in assembled form as it appears in the nonoperating position.
- FIG. 5 is a sectional view of the device of my invention in assembled form as it appears in the operating or drop-dispensing position.
- the illustrated form of the invention comprises an outer tubular member 10 having an open end 12 and a second end 14 comprising an end wall having therein a concentric circular opening 16, a vial 18 received in the open end of said tubular member having a resilient stopper 20 sealing its open end, said stopper having an annular shoulder 22 thereon to prevent reciprocation of said stopper in said vial.
- the stopper 20 also has a projection 24 thereon which is concentric with the stopper. Fluid passage 26 traverses said stopper 20 and projection 24, said projection extending through and beyond said end wall of the tubular member 10.
- the projection 24 has an externally raised ring 28 which forms a snap-fit on the exterior of the concentric circular opening to restrain the projection against longitudinal movement within the opening 16.
- the stopper 20 also has an internally hollow convex dome-like configuration 30 in proximity to the inner end of the projection 24 which is adapted to be compressed when the vial 18 is fully advanced in said tubular member 10 toexpel a drop of fluid from said vial through the fluid passage 26.
- the tubular member 10 has a skirt-like extension 32 on its outer surface surrounding said projection, a cap 34 enclosing that part of the projection extending beyond the end wall, the exterior of said cap forming a seal with the interior of said skirt, said cap also having on the interior I of its closed end, a projection 36 thereon adapted to seal on the exterior of the end of said projection 24 to thereby'form a two-point seal.
- annular shoulder 22 has an external diameter equal to or slightly larger than the inside diameter of tubular member 10 to maintain accurate alignment of the parts and provide a smooth action or feel for the operator.
- the device is assembled by filling the vial 18, inserting stopper 20 within the vial and then placing the stoppered vial within the tubular member 10.
- the projection 24 is then pulled through opening 16 until ring 28 snaps into place as shown in FIG. 4.
- the drop of reagent is dispensed by the application of a squeezing force between vial l8 and tubular member 10, causing the compression of the of said tubular member having a resilient stopper seal- I ing its open end, said stopper having an annular shoulder thereon to prevent reciprocation of said stopper in said vial, said stopper also having a projection thereon which is concentric with the stopper, a fluid passage through said stopper and projection, said projection extending through said concentric circular opening and beyond said end wall of the tubular member, said projection having an externally raised ring which forms a snap-fit on the exterior of the concentric circular opening to restrain the projection against longitudinal movement within the opening, said stopper also having an internally hollow, imperforate convex dome-like configuration in proximity to the inner end of said projection and extending beyond the end of said vial which is adapted to be compressed when said vial is fully advanced within said tubular member to expel a drop of fluid from said vial through said fluid passage.
