CLOSURE FOR ooN'rAINERs;

Specification of Letters Patent. Patented Den. 142, 11915,

Application filed April 8, 1914. Serial No. 830,395.

To all whom it may concern:

Be it known that'I, MORTIMER BYE, a citizen of the United States, residing at Indianapolis, Marion county, and State of Indiana, have invented and discovered certain new and useful Improvements in Closures for Containers, of which the following is a specification.

My invention relates to closures for containers, and more particularly to closure means adapted to hermetically seal a receptacle which is adapted to retain and aseptically protect a liquid, or other medicament, and in which it is desirable that the container should be quickly and easily unsealed to permit of the ready utilization of the contents of the container, as for instance, for an injection, hypodermic or otherwise. I

The objects of the invention are to provide closure means which shall be effective in antiseptically sealing the container, and yet may be instantly and readily removed when p the contents of the container are to be utilized, and to also provide means of such a character that no portion thereof will become mingled with the contents of the container when the seal is broken.

With these objects in view, my'invention is embodied in preferable form in the device hereinafter described and illustrated inthe accompanying drawings.

In these drawings, Figure 1 is a side view in elevation of a container and closure embodying my invention; Fig. 2, a longitudinal section; and Fig. 3, a view showing the container in section and the closure removed and separated from the container. j

The invention is shown .in the drawings as applied to an ampul, but it is capable of utilization with containers of various types and adapted for a variety of purposes, although it is to be understood that it is specifically applicable to such containers as serve to hold a single chargeof contents and in which the closure is merely operable to close the container until the first and only use of the contents and is not thereafter replaced or retained.

Broadly stated, the invention consists of a closure for a singlecharge container which.

forms the sole closing means for the container, which is aseptic and which lies able adhesive and joint sealing medium, whereby upon a slight pressure or blow imparted to the closure member it may be easily detached from the container, carrying with it the sealing substance in a clean separation, without leaving particles of the closure or sealing medium in the dispensing channel of the container.

In the accompanying drawings, 1 is the body of a double end ampul, made of glass,- as is usual, and adapted to contain a charge of a suitable medicament in liquid form for injection or other mode of administration. The ampul shown has two contracted necks 2 and 3 providing restricted dispensing passageways, open at their ends. The invention, however, may be applied to an ampul or other container having but one open end. The container is preferably provided at each open end with an outwardly flared annular lip 4, which provides a seat exterior of and beyond the contracted neck of the ampul, in which seat freely fits a loose, exterior closure member 5. This closure preferably consists of a spherical or otherwise curved body of antiseptic material, glass being preferably used, and it is placed loosely in the seat,

thus closing the end of the container. The closure 5 is secured removably in place and the joint between the same and the container hermetically sealed by means of a coating of adhesive material 6, such as paraffin, or a composition of'a suitable nature. This sealing and securing medium is of such character that it may be readily broken or severed by the application of a slight pressure to the closure. A portion of the body of the closure member projects beyond the edges of the flared cup lessening the area of adhesive surface within the cup and enabling the member to more freely clearthe lip and to be readily removed. To enable the .closure to be more easily and promptly dislodged from its seat, it is provided with a tongue 7, or similar projection, which also extends beyond the edge of the container and affords means whereby upon a slight pressure or blow imparted thereto, the closure and the sealing medium adhered thereto may be detached from the container.

The flared seating end of the container provides a cup for the paraffin, or other adhesi-ve sealing medium, which provides a secure attaching surface therefor and at the same time spaces thegreater part of the Although, of course, the loose exterior temporary closure member might be in the form of a disk of any suitable material and used with a container having a plain cylindrical mouth, yet the glass spherical body in conjunction withthe flared mouth of the container has been found to provide aclosely fitting antiseptic and readily removable closure.

The invention is especially applicable for use in connection with ampuls since iten- I ables a wholly antiseptic container to be employed, and avoids the danger arising from the use of ampuls having closed' ends integral with the glass body of the ampul, and

which must be broken to permit the use of r the contents, and in the utilization of which there is a possibility of particles of the broken glass becoming mingled with the con-tents.

. .Having thus described my invention, what I claim is:

1. An ampul having a closure member seated loosely at the mouth thereof exterior of the neckof the ampul and projecting beyond thelip of the mouth to facilitate removal and capable of ready dislodgment 'from said seat by asli ht pressure, and a readily breakable adheslve sealihg medium joining said member and container and confined to the surfaces thereof exterior of the neck, said member forming the sole closing means for said mouth.

2. Anlampul having a neck and an outwardly flaring mouth beyond said neck, a

closure member larger than the neck area and loosely seated in said mouth, a readily breakable adhesive sealing medium joining said member and mouth and confined to the area beyond the neck opening, said member extending beyond the lip of the mouth and 4 being readily dislodgeable by a slight pressure only applied thereto.

3. An ampul having a neck and having an outwardly flaring mouth beyond said neck,. a closure memberaloosely seated in said mouth and closing the entrance to the neck, said closure having a portion thereof extending beyond the lip of the mouth and having a tongue projecting outwardly from the body of the member beyond the said lip and providing means to be engaged for. dislodging the member from its seat and a readily breakable adhesive medium joining said member and the wall of the mouth only.

4. A glass ampul having a contracted neck and having a mouth flaring outwardly beyond said neck, a substantially spherical .glass closure member seated loosely in said 'mouth and closing the entrance to said neck,

a readily breakable adhesive sealing medium joining said closure member and the wall of the mouth and confined to the area of contact between the member and ampul beyond the opening to the neck, said member having an outwardly projecting tongue extending beyond the lip of the mouth. A

In witness whereof, I have hereunto set my hand and seal at Indianapolis, Indiana, this 6th day of April, A. D. nineteen hundred and fourteen.
