  • Figure 14 is a plan view. partly in section and Partly inphantom of analternative embodiment of the present invention.
  • Figure 15 is an enlargd, fragmentary section of the 2,693,803 Patented Nov. 9, 1954
  • Figure 16 is an enlarged fragmentary plan view of the the removable needle in place.
  • Figure 17 is a fragmentary section showing the method of inserting the needle in the barrel.
  • the syringe includes a barrel indicated .generally by the numeral 20, which barrel is provided at its upper end with a flange 21, preferably rectangular in shape as shown in Figure 2, to prevent rolling 'of the syringe.
  • the entire barrel 20 is formed of polyethylene plastic and the walls have a thickness in the order of 60/1000 inches, which thickness of polyethylene plastic has been discovered to give a good vapor moisture transmission characteristic thus enabling storing of medicants over long periods of time without undue loss.
  • the upper end of the barrel 20 is provided with an extension 22 in the form of a centrally disposed post or boss.
  • This post is notched as at 23 throughout a portion only of its length. As shown in Figure 7, there may be three of such notches 23.
  • the interior of the barrel 20 is hollow and at the upper end the walls thereof taper as at 24 converging towards the needle 25.
  • the needle 25 is driven, as hereafter explained, centrally throughout post 22 and as shown in Figures l-6 has its inner end aligned with the edges of the tapered walls 24.
  • Figure 8 an alternative structure is shown in Figure 8 wherein the needle 25 is not driven completely through the end of the barrel 20 and terminates short thereof as shown at 26.
  • a bore 27 communicates the interior of the hollow needdle 25 with the interior of the barrel 20 and a shoulder 28 is formed adjacent the bore.
  • the needle 25 is provided with a tapered open end 29.
  • a cork 30 is provided, which cork 30 is hollow and is provided with a flange 31 at one end and a male thread member 32 at the other end thereof.
  • the cork 30 is hollow and at its upper end, the walls are provided with a converging taper 33.
  • the upper end of the cork 30 is also provided with a thickened solid portion 34.
  • the cork 30 is manufactured from polyethylene plastic and its walls, except in the thickened portions, are of the order of V inch thick.
  • the interior or bore of the cork 39 is preferably of a smaller diameter than the exterior of the post 22 thus providing a press fit between the post and. the interior of the cork which requires a slightexpansion of the walls of the cork when the plug is inserted and thus insures a good seal.
  • the barrel 20 is adapted to receive a rubber piston 35.
  • This rubber piston is provided with a female thread 36 and a pair of ridges 37 and 38.
  • the female thread 36 extends into the rubber plunger 35 at least beyond the first ridge 38.
  • the cork 30, when it is desired to use the syringe, is removed from the post 22. and the male end thereof is threaded into the female thread 36 in the rubber plunger.
  • the male thread 32 is preferably made $5 or @io inch larger in diameter than the interior diameter of the female thread 36 so that upon threading of the male member 32 into the piston 35, the piston'35, will be expanded laterally. This condition is shown in Figures 4 and 5.
  • the disposable syringe may be .prepared for shipping to a customer priorto filling with medicant as follows:
  • the cork 30 is pushed further on to the post 22 to the position shown ,in Figure 4, fin which case the syringe issealed, It willbe apparent that there is provided by the cork 30 three seals, one seal occurring by reason of'the coaction of the post22 with the interior'of the cork and the expandingjof the cork pensated for by the exposed to moisture in the region of the post.
  • the second seal occurs between the outside of the upper end of the needle and the material of the thickened end 34.
  • the third seal is provided to the interior of the upper end of the needle by reason of the plug 40.
  • the tapered walls 33 serve as a guide to center the needle as near as possible in the center of the thicknened portion 34 to prevent the needle from moving sideways and perhaps emerging from the cork.
  • Figure 13 is shown in order to more completely describe this action.
  • Figure 13 illustrates the condition of the needle and cork if one were to take and pull the material away from the sides of the needle. As shown at 41 and 42, the plug 40 would remain within the end of the needle as shown but not severed from the remaining material of the thickened end 34.
  • polyethylene is a waxy semi-crystalline substance which permits cutting by any sharp instrument with comparative ease.
  • the rigidity of polyethylene in the thick section is such that the plug cut by the insertion of the needle is substantially of the same diamter as the inside diameter of the needle and is certainly not larger than the interior of the needle as might be the case with a material having a much higher elastic deformation, such as, for example, soft rubber.
  • the tensile strength of polyethylene is such that the core produced by the insertion of the needle is sufficiently well attached to resist tearing away from the parent material when the needle is withdrawn.
  • polyethylene because of its waxy nature,'has a very favorable coeificient of friction and does not tend to cling to the side wall of the material when the needle is removed from the plug.
  • the male member 32 is inserted in the female member 36 to the extent that one or two of the threads thereof pass beyond the ridge 38.
  • the piston 35 in the ridge 38 when being driven into thebarrel is being pulled rather than pushed, and the ridge 37 is being pushed rather than pulled and the reverse action takes place upon the withdrawal of the piston from the barrel.
  • the piston is designed so that the needle 25 as shown at 50. This needle is driven through the center of the post 22 until it emerges in the interior of the barrel 20.
  • the mandrel 50 thus makes a small hole in the plastic material by merely spreading the material without cutting a core.
  • the needle 25 has its lower edges bevelled as shown at 51 and the needle follows a short space behind the mandrel 50. In this manner the needle is driven into the bore made by the mandrel 50 without cutting away any material and hence the needle is imbedded in the plastic material under hoop tension. As shown in Figure 8, the end of the needle may in fact terminate short of the interior of the barrel 20 and hence rest upon the shoulder 28 to give further support to the needle. However, this is not found to be essential.
  • FIG. 1416 there is shown an alternative embodiment in which the needle 25 is .not used.
  • the cork 30 may in all respects be similar to the cork 30 of the previous embodiment although it is apparent that a much shorter and smaller cork may be used.
  • the barrel 60 is essentially similar to the barrel shown in the previous embodiment and the piston 35 may be identical.
  • the difference in this embodiment lies in the fact that the post 22 at the upper end of the barrel is provided with an interior bore 61 and a short extension 62.
  • the bore 61 extends only partially into the extension 62.
  • the extension 62 forms an enclosure for the bore 61.
  • the physician desiring to use this embodiment of the invention will cut a portion of the extension '62 from the post 66 as shown in Figure 15 and will then insert upon the post 66 a conventional needle having an enlarged hub 63 with a tapered wall 64 adapted to fit the tapered end 65 of the post 66.
  • Such a needle is shown in Letters Patent of the United States No. 2,076,121. This condition is shown in Figure 16.
  • the walls of the barrel 20 have sufficient resiliency so that an operator can actually grip the piston 35 by depressing the walls of the barrel and hold the piston during the threading in or threading out of the male member 32 into the female member 36.
  • the male members 32 are preferably formed with a diameter or A inch in excess of the interior diameter of the female threads 36 to cause the expansion of the piston 35 as the threads are made up to insure that the piston has a'leak-proof contact within the walls of the barrel. This is important in case the piston 35 has taken a permanent set.
