A. E. SMITH Oct. 3, 1950 CLOSURE Filed Dec. 12, 1947 mm Ws. z U m 2 A m Patented Oct. 3, 1950 UNITED STATES PTENT OFFICE CLOSURE Arthur E. Smith, Los Angeles, Calif. Application December 12, 1947, Serial No. 791,429
I This invention relates to a closure. The general object of the invention is to provide an 'improved closure which may be used on bottles containing drugs or other material to be injected or otherwise dispensed.
s cmms. (ei. 1284-272) i and to prevent the vehicle 21 in the container A more specific object of the invention is to provide a container closure which includesa resilient, fiexible portion which may be manipulated to cause a fresh solution to be prepared in the container.
Another object of the invention is to provide container closure including a portion secured on the container and a second supplemental portion which is fiexible and which may be depressed to cause a drug in the first portion to be d'ischarged on the main closure.
into a vehicle in the container to prepare a fresh solution.
Another object of the invention is to provide a novel, fiexible container closure.
Other objects and advantages of my invention w'ill be apparent from the following description taken in connection with the accompanying drawings, wherein: i
Fig. l is a central, sectional view showing a container with my improved closure thereon;
Fig. 2 'is a view similar to Fig. 1, with the outer closure depressed;
F'ig. 3 is a section taken online 3--3, Fig. 1, and
Fig. 4 is a view similar to Fig. 1, showing a modification.
Referr'ing to the dra-Wing by reference characters, I have shown my irivention as embodied in a containerclosure which is indicated generally at iii. As shown, the closure is mounted on a bottle ll which has a reduced neck 12 with an external fiange lC' at the upper end thereof. The closure consists of a main body portion iii and an aux'ilary closure l5, both made of fiexible rubber or similar material. The body portion |4 has a skirt portion 46 with an internal flange ll at the lower end of the skirt. The flange I 'l engages beneath the collar E3 to hold the closure member in place.
The body of the closure includes an inwardly directed sleeve iii which fits with'in the container neck and has an axial recess i and a reduced axial recess which together form a shoulder 2 I. Above the shoulder I provide a pierceable diaphragm 22 and above the diaphragm I provide an axial hole 23 'which opens outwardly to receive a piercing member 24, to be later described.
Within the reduced recess 20 I arrange a medicinal pellet 25 and in the recess 19 and engagng the shoulder 2| I arrange a closure disc 26 which serves to confine the medicinal pellet in place from d'issolving the pellet.
The auxiliary closure I 5 includes a skirt portion Si? which engages the periphery of the main closure and has a peripheral fiange 3| by means of which the auxliary closure may be readily removed if desired. The lower end of the sk'irt of the auxiliary closure rests upon an external flange The auxiliary closure is provided with a hole 33, through which the piercing member 24 extends. The piercing member is provided With a head 34,'shown as disposed upon the outer surface of theauxiliary closure. With the parts in the position shown in Fig. 1,
` to prepare a solution the operator depresses the auxiliary closure and the head 34 of the piercing member, causing the pointed end 35 of the latter to pierce the diaphragm 22 and thus displace the disc 26, causing the pellet 25 to enter the solvent 2? and thus prepare a fresh solution. The piercing member is then pulled out of the diaphragm 22 and since the parts are made of rubber, the hole made by the piercing member will be selfsealing.
To use some of the freshly prepared solution, the operator may remove the auxiliary closure l5 and insert a hypodermic needle through the diaphragm 22 and thus extract some of the contents of the container, or, if desired, the op- 1: E3 erator may remove the piercing member 24 from the auxiliary closure and may then insert the hypodermic needle, rst through the hole 33 and then through the diaphragm 22, to extract the contents.
In Fig. 4 I show a modification in which parts similar` to those previously described are designated by double iprimed reference numerals. In this further modification the parts are like those shown in Fig. 1 except that the piercing member 24" has an outer head 34" and in addition has an inner head or collar 50 which engages the lower face of the auxiliary'olosure. The collar 5b may tightly engage the piercing member 24"' or it may be made an integral part thereof and may be secured in place by stretching the material of the auxiliary closure.
The operation of the modification shown in Fig 4 is the same as that described above except that the auxiliary closure and piercing member are constrained to move together, thus assuring that the 'piercing member will not be displaced.
In the present application, Ser. No. 791,429', filed December 12, 1947, the claims are directed to a piercing member extending through a, hole in the auxiliary closure and movable with the auxiliary closure to displace a sealing disc carried by the main closure.
In applicant's copending application Ser. No. 791,428, filed December 12, 1947, the claims are directed to a tubular disc displacing member wherein the tube is provided with a fiange which is arranged within the auxiliary closure. In copending application Ser. No. 4,089, filed January 24, 1948, the claim is directed to the main and outer closures, wherein the main closure includes a cupped diaphragm` portion and the outer closure includes a stem which engages the cupped portion to cause release of a sealing disc.
In copending application Ser. No. 4,193, filed January 24, 1948, the claim is directed to the closure which includes a corrugated diaphragm engageable by a releasing stem carried by an auxiliary closure.
From the foregoing description it will be apparent that I invented a novel closure which can be economically manufactured and assembled and which is highly efficient for its intended use.
Having thus described my invention, I claim:
1. A cl-o's "'e comprising a body portion an aux ry ciosure portion, said main body port-ich having a shirt adapted to engage the outer surface of the neck of a bottle, said shirt having internal flange adapted to engage benea battle neck fiange, said skirt also having an external fiange, said body portion having a sleeve portion adapted to t within a bottle nezk, said sleeve portion having an axial recess 'ein and having a second axial recess smaller the first recess, a sealing disc in said :rst medicinal tablet in said second recess, a closing the inner end of the inner 1; said body portion having an axial hole therein extending cut-wardly from said diaphragm, auxiliary closure including a fiexible body having a skirt thereon, said skirt engaging the periphery of said body portion and engaging the fiange on said body portion, said auxiliary clort having an external fiange thereon, and member having a sharpened lower end i said hole, said auxiliary closure having en al hole, said piercing member extending through said hole, said piercing' member havingI a flange thereon, said flange being disposed on ie outer surface of said auxiliary closure r en 1;er being movable with said outer auxiial'y cie-sure member.
