Dec. 24, 1929. R. B. WAITE MEDICAMENT CONTAINER Filed Sept. 26, 1927 Patented Dec. 24, 1929 UNITED STATES PATENT OFFICE RALPH B. WAITE, OF SPRINGVILIJE, NEW YORK, ASSIGNOR TO THE ANTIDOLOR MFG. C O. INC A CORPORATION OF DELAWARE MEDICAMEN'I. CONTAINER Application filed September 26, 1927. Serial No. 221,909.

My invention relates to medicament containers andvis particularly concerned with containers for medicaments which are administered hypodermically.

The object. of the invention is to provide an improved stoppered bottle from, which doses of the medicament may be withdrawn by a hypodermic syringe Whose needle is made .to pierce apliable plug. 1o Medicament containers of these general characteristics are old in the art, but, as before stated, I provide an improved construction the features of which will be pointed out as this'description proceeds.

In the accompanying drawin Y Fig. 1 is an'elevational view 0 the medicament container of my invention; Fig. 2 is a sectional view, taken on plane of line 2-2 of Fi land looking in the go direction indicated %y the arrows, and being on a somewhat larger scale;

Fig. 3 is an under side view of the pliable plug to which reference will be made;

Fig. 4 is a sectional view through a hot- '25 tle provided with a closure in accordance zvith my -invention,.illustrating a modified orm. The container itself is in the form of a bottle 4 having the neck 5, formed onthe 30 outside with-threads 6- and on the inside with ashoulder 7. I

The plug'8 of soft pliable material, such as soft rubber or composition, isdisposed in the upper end of the bottle neck, this plug being circular and of such diameter as to fit just snugly within the enlarged upper. end of the bottle neck as shown. Furthermore, this plug is of athickness e ual to the distance between the shoulder and the top of the bottle. The resultis that at no time is the plug under any more pressure'than that which is absolutely necessary-to keep it in its .place when the bottle is inverted.

The underside of the plug 8 is.hollowed out hemispherically as indicated at 9, in order to reduce the thickness of the central portion at 10 for a purpose which will be referredto resently. I

metal cap-11 is threaded onto the bottle neck, as indicated, a cork disc 12 being pro- .vided in the cap to be forced down upon the top of the bottle. In screwing home the cap 11, no pressure'is exerted upon plug 8, by reason of the arrangement and relative dimensions which have been referred to.

WVhen it is desired to charge a hypodermic syringe, the cap 11, with its disc 12, is unscrewed and removed, the needle of the hypodermic is made to pierce the central portion of the plug 8-, the container inverted, and the syringe plunger actuated. The syringe needle is then withdrawn and the aperture in the plug 8 is self closingl due to the nature of the material of which it is made.

By providing an arrangement in which the plug 8 is neither compressed nor relied upon normally to stopper the bottle, I am enabled to employ, for the plug 8, material best adapted for the purpose of closing the piercings and best from the standpoint of cleanliness. Furthermore, the arrangement whereby the top of the plug is flush and edge to edge with the top of the bottle neck contributes further to this essential cleanliness. In Figure 4, I show a modified form to act as a treated gauze strip container. In this case the lug 8 is pierced to permit of withdrawal o the gauze therethrough with tweezers.

I claim: 1 1. In combination, a medicament container having a shoulder on the interior of the neck thereof, a plug disposed in said neck restin on said shoulder, the upper ends of the p ug and container being flush to promote cleanliness, said plu being of a pliable material which is sel -closing to punc- 'tures, and-a cap having a portion coacting with said flush upper ends to further tomote cleanliness, said portion exten nfi across andin contact with the said fll18 upper ends of said plug and said container, said cap having an attaching wall depend-- ing from said portion engaging the exte-v rior of the neck of the container.

2. In combination, a medicament container having a shoulder on the interior of the neck thereof, a plug disposed in said neck resting on said shoulder, the upper end of thelplug and cor tamer being fiushto 109 promote cleanliness," said plu being of a pliable material which isso f-closin to punctures, saidplug being reduced in t ckness from the under surface thereof, a ca having a portion coacting with said flus upper ends to ffiuther promote cleanliness,

said ortion' extendin across the upper end of-sald plug and sai container,a disk coextensive with said portion engaging the under surface thereof and the upper ends of said plug container, said cap havin a wall depending from said portion an screw threaded to the exterior of the neck of the container. Y

3. combination, a medicament container having a shoulder on the interior of the neck thereof, a plug disposed in said neck and restin on saidshoulder, said plug being of a'plia le material which is self-closing to punctures, a 4 cap extending completely across the plu' and neck and having a depending attac ing wall-engaging the exte-' rior of said neck, the outer portions of said neck and plug at their junctions being flush and crossed by said cap. 4

In witness whereof, I hereunto subscribe my name this 22nd RALPH B. WAITE.

day of September, 1927.
