Complete Specification for the invention entitled: PLUNGER- OPERATED APPT JIO? OR The following statiment is a full description of this invention including the best method of performing it known to us/nr.,:- ]a- This invention relates to a plunger-operated applicator for use in delivering fluid from a smalldiameter cylindrical storage tube.
For administering small quantities of drug fluids, micropipettes have hitherto been used.
However, when using a micropipette it is necessary for the drug fluid to be available in a relatively o0a large stock vessel which allows filling, of the 0000oooo Soo micropipette. Drug fluids which are easily contaminated 0 C 3 0 0 10 or are very expensive to produce (for example interferon 0000 000o solutions) cannot be made available in this way, 0000 o o 0 and thus cannot be administered by means of a micropipette.
According to the present invention there 00ooo0 is provided a plunger-operated applicator for use 15 in delivering fluid from a small-diameter cylindrical 00 0 oo storage tube, the applicator comprising a tubular o0 00 body having an axial passage extending from end to end thereof, a first cylindrical portion of ot 0 o o said passage which opens at one end of the said body being arranged to receive a said storage tube as a sliding fit therein, a second cylindrical Or00 0o' nortion of said passage which opens at the other oo000 end of said body having an operating plunger slidably mounted therein, and an intermediate portion of saidi passage at the inner end of said first cylindrical portion being of conical configuration for receiving and releasably securing the end of the said storage tube as an interference fit therein.
In relation to a specific storage tube, the dimensions of the applicator should be such that, when inserted into the applicator, the storage tube still protrudes from the said one end of the applicator. Furthermore the stroke volume of the i LLI 1 'A 2plunger should be greater than the storage volume of the tube so that, when the plunger is actuated, complete emptying of the contents of the storage tube can take place.
When using a preferred embodiment of the invention, fitting of the tubular applicator with a storage tube which contains a drug fluid and is initially still closed at both its ends, for example by means of welds, is carried out as follows.
First the plunger is pulled out by means of its handle rp to a stop; one end of the storage tube, inwardly of the weld, is then cut open by means ooo, of scissors, and the open end of the tube is inserted 0 o into the said one end of the applicator body until *O 15 the cut end firmly engages with and is held by 6900 0oo the conical surface provided for this purpose.
0 o Then the other end of the tube, protruding from o the applicator body, is cut off inwardly of the weld. Then, when the piston is pushed in, the 4 20 fluid contents of the storage tube can be expelled So drop-wise for application as needed.
Q An embodiment of the invention will now 0aO 0 be described by way of example and with reference to the accompany drawings, in which;- Figure 1 is an elevational view, half in 0oII axial cross-section, of an applicator according on 0 to the invention; Figure 2 is an axial cross-sectional view of a slightly modified plunger for the applicator of Figure 1; and Figure 3 is an elevational view, partly in axial cross-section, of a small-diameter cylindrical storage tube, e.g. a capillary tube, for use with the applicator of Figure 1.
Referring to the drawings, 1 is the tubular body of the applicator, 2 is a first cylindrical portion of an axial passage extending through the applicator body, matching the diameter of the storage 1 L ~~rir 3 tube which is to be slidably inserted and 3 is the inner conical portion of the said passage which makes an interference fit with the end of the storage tube. The inner conical portion 3 leads into a second cylindrical portion of the passage which provides a cylindrical cavity 4 for a plunger The plunger has a shank 6 and a handle 7. A stop 8 is provided for the plunger 5. A protrusion 9, which preferably has the form of a supporting bead running all around the body 1, and which is located off-centre in the direction of the applicator tip 10, prevents contact of the storage tube, when rttI Itit has been cut open and inserted into the applicator, with a supporting surface, for example a table 15 top, whereby contamination is prevented.
o0 It is advantageous if the handle 7 of the plunger is of polygonal form, for example in the form of a triangle or square, with corners protruding radially beyond the circumference of the applicator o 20 body. Such an arrangement prevents the applicator from rolling away when placed on a work top.
Figure 2 shows a cross-section through a plunger 5 of somewhat different form, with a shank 6 and a handle 7 for insertion into the cylindrical cavity 4 of the applicator of Figure i.
o Figure 3 shows a storage tube for use with the applicator of Figure 1, which is closed by o welds 11 and 12 at its ends and contains a drug Sfluid 13.
~I
The applicator is preferably made of plastics such as polyethylene or polypropylene.

Claims (3)

  1. 4-- THE CLAIMS DEFINING THE INVENTION ARE AS FOLLCWS:- I. A plunger-operated applicator for use in delivering fluid from a small-diameter cylindrical storage tube, the applicator comprising a tubular body having an axial passage extending from end to end thereof, a first cylindrical portion of said passage which opens at one end of the said body being arranged to receive a said storage tube as a sliding fit therein, a second cylindrical portion of said passage which opens at the other i10 end of said body having an operating plunger slidably mounted therein, and an intermediate portion of said passage at the inner end of said first cylindrical portion being of conical configuration for receiving and releasably securing the end of the said storage tube as an interference fit therein. 2. An applicator as claimed in claim i, wherein the said tubular body is formed with a radially outwardly extending protrusion at a location between the centre of its length and the said one end of the body. 3. An applicator as claimed in claim 2, wherein 41 the said protrusion comprises an annular bead extending all around the said body. 4. An applicator as claimed in any of claims 1 to 3, wherein the said plunger has a handle at its outer end, which handle is of polygonal shape and is wider than the said tubular body. An applicator as claimed in any preceding claim, including stops for limiting the inward and outward movement of the said plunger. I, 5
  2. 6. An applicator as claimed in claim 5, in combination with a said small-diameter cylindrical storage tube, wherein the stroke volume of the plunger is greater than the storage capacity of the storage tube.
  3. 7. A plunger-operated applicator substantially as hereinbefore described with reference to the accompanying drawings. Dated this 18th day of February 1987 0oI DR. KARL THOMAE GmbH o a Patent Attorneys for the Applicant 0 c o F.B. RICE CO. o 00 04 0 0 00 O 0 0 00 1 o 44 41 1
