Application filed 31115 16, 1927. Serial No. 206 ,242
This invention relates to a medicinal con-' tainer or ampul. V The general object of this invention is to provide an improved drug containing ampul f whereln the drug is hermetlcally sealed 1n the ampul.
Another object of the invention is I vide a drug containing ampul having an improved form of stopper therein for eject ing the contents of the ampul. f
A further object of-the invention is to provide an ampul having novel means thereon for coacting with a syringe to form afluid tight seal between the Syringe and the ampul.
' neck 12 of the ampul. The cap is preferably A. specific object of the invention is to provide a novel closure for the discharge end of an ampul.
Other objects and advantages of, the invention'will be apparent from the following description taken in connection with the accompanying drawings wherein:
Fig. 1 is a side elevation of my improved ampul.
Fig. 2 is an enlarged central longitudinal pul comprises a body-portlon 24 provided insection through my improved ampul. Fig. 3 is a view similar to Fig. 2 with the tip removed from the closure and the stopper" moved towards the discharge end of the am-l pul to eject the contents therefrom.
Fig. 4 is a front elevation of the discharge 1" V -a feather edge on the front face of'the body end of the ampul as shown in Fig. 3.
Fig. 5 is a fragmentary central lo-ngitudi nal section of the ampul showing the stop-fl per moved to itsfullest discharge position, and
Fig. 6 is a section of the cap. I
Referring to the drawings by reference characters I have indicated my improved,
ampul generally at 10. This ampul is primarily adapted for use ina hypodermic syringe of the ampul containing type. The ampul may be of any desired type but is preferably of a size to hold the amount of drug necessary for one injection.
The ampul 10 which is preferably made of' glass, comprises an elongated hollow cylindrical body portion 11 terminating at one end in a reduced tapered open ended neck 12. The other end of the ampul is preferably left- :to pro- {and the ampul.
s't-raightand open as indicated at 14 andis adapted to be closed by a; stopper 15.
Adjacent the endoft-he tapered neck 12 and integral therewith I providean outer annular bead16. The open end of the neck j 12 is adapted to be closed bya cap 17 which comprises a body portion 18 including askirt l9 and a reducedv tip 20. WVithin the body portion 18 I may provide an annulargroove 21 in which the annular head made of agood grade of rubber vulcanized to the desired degree of hardness. When the' cap 17 is placed on the ampul ,it iss'lightlydistorted so that the'groove 21 tightly engages the bead 16 and the skirt 19 of the'cap tightly engages the tapered neck '12, thus forming a fluid tight seal between the cap The stopper 15 in the "open end 14 of the amterm'ediate its length with an outer annular groove 25'.- The forward end of the stopper provided with a'protuberant' conicaltip 26 'andaconical'groove 27 at the juncture of the tip 26 and the body 24.- The groove 27 forms inner walls of they body 11, thus forming a i fluid tight'seal betweenthe ampul body and the'stopper. This seal prevents fluid in'the ampul from leaking past the stopper. when the -contents of the ampul. are being ejected;
The conical tip 26 of the stopper forces out more of- ,the liquid in the ampul than would a flat ended stopper, since theconical end enters the neck 12 as shown in Fig. 5.
thereby assuring an;approximately full dis charge of the contents of the ampul. The stopper 15 like the cap 17 is preferably made of a good grade of'rubber' vulcanized to the F desired hardness.
To preparea filledampul for use it is only neces'sary'to remove-the tip 20 of the cap 17 by cutting it at the juncture with the body portion. This exposes the recess 22 which then forms an aperture through which the contents of the ampul may be expelled when the stopper 15 is moved towards the neck 12.
After removing the tip of the ampul cap the ampul may be inserted into the barrel of a syringe, the cap 17 engaging the syringe adjacent the discharge end thereof and the stopper 15 being adapted to be engaged by a plunger rod in thesyringe. V a
To eject the contents of the ampul after it isplaced in an operative position in a syringe the stopper 15 is moved within, the ampul body 11 towards the neck 12, thus causing the stopper to act as a piston to expel the contents of the ampul.
As pressure is applied on the stopper 15 to expel the contents of the ampul the cap 17 will be forced into very tight engagement Wltll the syringe, the more pressure required to move the stopper the tighter the cap 17 will engage the syringe, thus creating a fluid tight seal between the discharge end of the ampul and the syringe.
The ampul may be filled before or after the cap or stopper are inserted, in any desired manner.
From-the foregoing description it will be apparent that I have provided an improved container or ampul which can be economical- 7 1y manufactured and which is highly efiicient whereby when a portion of in use.
Having thus described my invention, what I. claim vis:
1. An ampul comprising a hollow body portion constricted at one end to form a tapered neck, an aperture in said neck communicating with the interior of said hollow body, an external beadon said tapered neck, a resilient cap arranged on said neck and engaging the surface of said head and the front end of-said neck, a recess in said cap extending beyond the front end of said neck said cap is cut away communication is formed through said cap to the interior of said ampul.
2. An ampul comprising a body portion constricted-at one end to form a tapered neck, an external bead on said neck, a resilient cap,
said cap including a body portion and a tip, arecess in saidbody portion fitted over said neck, asecond recess in which said bead is positioned, a third recess in said body portion extending into said tip, whereby when I said tip is cut away atits juncture with said body portion anaperture is formed through said cap affording communication with the interiorof said ampul. I I
3. An ampul comprising a hollow body, a closure forone end of said body, said closure including a body portion and a severable tip, means providing a fluid tight o1nt between Stud ampul andsaid closure, said means comprising a per pheral bead on said closure,
