MEDICAMENT DISPENSING CARTRIDGE Original Filed July 1, 1921 Patented Dec. 9, 1930 UNITED STATES PATENT OFFICE HARVEY S. COOK, 0F VALPARAISO, INDIANA., ASSIGNOB TO COOK LABORATORIES, INC.,

A CORPORATION 0F DELAWARE Original application filed July 1, 1921, Serial No. 481,997. Divided and this application led December 20, 1926. Serial No. 155,838.

This invention relates to sealed medicament-dispensing containers or so-called cartridges for use in a hypodermic syringe of the type in which such a cartridge is embodied as a separable element adapted tobe collapsed to expel its contents through a canula piercing the cartridge.

The subject of the in-vention is a collapsible cartridge of the plugged tube type embodying certain features originally disclosed in my co-pending application led July 1, 1921, Ser. No. 481,997, of which this application is a division; the said cartridge embodying a generic invention more broadly claimed in said original application.

In the drawings:

Fig. 1 is a side elevation of a cartridge embodying the invention;

Fig. 2 is a longitudinal section thereof;

Fig. 3 shows a cartridge in association with the canula and plunger of a syringe-like instrument with which the cartridge is intended to be combined;

Fig. 4 shows the cartridge collapsed.

The cartridge embodies a rigid tube 5 of substantially uniform bore. This may be a section of commercial glass tubing, which,

though ordinarily having irregularities inA bore, ma be considered as of substantially uniform ore in the sense of a straight bored tube through which a resilient plug may be pushed. Sealing closures are provided by elastic Stoppers 6 and 6, which are preferably of molded rubber, fitted tightly in opposite ends of the tube. In use in an injectthe canula and plunger of a syringe-like instance the plug 6, 1s pierced axially by a canula, represented in Fig. 3 by the double pointed hypodermic needle 9; and the other plug 6a is adapted to be pushed by the plunger 10 through the tube to expel the contained anesthetic or other medicament solution through the canula. a thick walled Cupshaped plug With its cavity facing outward. The cavity provides the thick Walled annular portion 7 and closed or imperforate thick walled inner end portion 8, which is of reduced thickness at the central part of the plug. This cup-shaped plug provides a substantial length of exte- The plug 6 is shown as' rior cylindric surface in tight frictional engagement with the tube and of substantially re uced axial thickness to be pierced by the canula, thus facilitating the piercing operation. While the inner im erforate wall 8 pierced by the canula is thin 1n relation to the length of the plug, it is of such substantial thickness as to enable the compressed stopper to form an effectual seal around the canula.

Before using the cartridge, the practitioner may pour an antise tic fluid into the cavity of the plug and after a few moments pour out the fluid and then immediately pierce the plug so sterilized with a sterile canula.

As both plugs 6 and 6EL are substantially alike in the illustrative embodiment of the invention shown in the drawings, either may in this instance serve as the plug to be ierced or as the piston plug to be forced into or through the tube to collapse the cartridge. When this form of plug with its cavity facing outward is use as a piston plug, it will be seen by reference to Fig. 3 that when the plug 1s forced in by the syringe plunger l0 the annular wall of the plug will be compressed and thereby forced tightly against the inner end of the tube and conform 'to irregularities in the bore of the tube during the ejecting action, promoting maintenance of a good seal.

I claim as my invention:

1. A cartridge for hypodermic syringes comprising a sealed li uid container embodying a ri d tube olf substantially uniform bore an stoppers in opposite ends of the tube, said Stoppers comprising substantially cup-shaped thick walled plugs of resilient material arranged with their cavities facing outwardly, said plugs adapted one to be pierced by a canula and the other to be forced through the tube to expel its contents arran ed with their cavities facing outward- 1 eiter of said lugs adapted to be forced through the tu e to ex el its contents tlllrough ak canula thrust t rough the other p ug.

3. A cartridge for hy odermic syringes comprising a sealed'me icament container embodying a rigid tube of substantially uniform bore, having in one end a sealing c10- sure to be pierced by a canula, and having in its opposite end a piston plug comprising a thick walled cup-shaped stopper of resilient material arranged with its cavity outward and presenting a thick Walled tubular flexible outer end portion to be engaged by a plunger to push the piston plug through the tube.

In testimony whereof, I have signed my name to this specification.

HARVEY S. COOK.

arran ed with their cavities facing outwardl eit er of said lplugs adapted to be forced through the tu e to ex el its contents through a canula thrust t rough the other 3.gA cartridge for hy odermic syringes comprising a sealed' me icament container embodying a rigid tube of substantially uniform bore, havln in one end a sealing c10- sure to be pierce by a canula, and having in its ogposite end a piston plug comprlsing a t 10k walled cup-shaped stopper of resilient material arranged with its cavity outward and presenting a thick walled tubular exible outer end .portion to be engaged h a plunger to push the piston plug through t e tube.

In testimony whereof, I have signed my name to this specification.
