MULTIPLE CONTAINER Filed Aug. 14, 1950 Patented Dec. 8, 1953 MULTIPLE CONTAINER Paul Hauduroy, Paris, France Application August 14, 1950, Serial No. 17 9,128
Claims priority, application France August 13, 1949 7 Claims.
It is frequently necessary, especially in medical practice, to mix together, at the time of use and not before, two substances that are to be retained in a sterile condition and which, if previously mixed, would have some essential properties of either or both the substances, destroyed or impaired.
Such is the case for example with certain antibiotics such as arsenical and other salts and penicillin derivatives, which are to be dissolved in an appropriate solvent at the time of use, or further bacterial ferments which are to be mixed with a sterilized fermentable liquid or serum.
It is the object of this device to provide a device, whereby two liquid or solid (e. g. pulverulent, crystallized, etc.) substances may be retained separate from each other within a sealed container for an indefinite period of time, and then mixed together when necessary without having to open said container, and thus without allowing either of the products to come into contact with the atmosphere.
With the above and. further objects in view, my invention essentially consists in a composite container for the purpose specified, which comprises a primary container adapted to contain a first ingredient of a mixture and having a top opening, a secondary container containing another ingredient of the mixture and secured in the primary container near the said top opening thereof, said secondary container having at least part of its bottom made of a frangible material, a deformable sealing means sealing the common top of both containers, and a perforating member in said secondary container having its bottom edge adjacent the frangible bottom part of said secondary container and movable under pressure exerted from outsidethrough said deformable sealing means to perforate said frangible bottom part and allow said other ingredient to fall into the primary container there to mix with said first ingredient.
The primary container may take the form of a flask, and the secondary container that of a generally cylindrical cup with a flat frangible bottom and an open flanged top restin on the top surface of the flask opening.
' The deformable sealing means may consist of a disc of rubber or equivalent material and an annular cap sealingly engaging the periphery of said rubber disc to seal the composite container as by a crimped attachment round the neck of th flask. Preferably, I may further provide a comparatively rigid, but removable, outer protecting cover over said deformable sealing means, removal of said outer cover uncovering the cen- 2 tral portion of said rubber disc for actuation of the perforator but still preserving the sealed condition of the composite container.-
The perforator member may comprise a slotted metal tube having a pointed tapering bottom end adapted to rest against the bottom of the secondary container until pushed down to puncture the same.
An exemplary embodiment of my invention will now be described by way of illustration and not of limitation, as applied to a flask for an antibiotic, in which the two substance to be mixed together comp-rise, the one a solvent or a serum placed in the bottom of the flask, and the other. an antibiotic, e. g. consisting of a powder placed in a frangible cup near the mouth of said flask.
In the accompanying drawings,
Fig. 1 is an enlarged view in axial section of the top of a flask arranged in accordance with the invention.
Fig. 2 is a similar view after removal of the protecting cover or cap,
Figs. 3 and 4 are a perspective and a developed showing, respectively, of the perforator member, and
Fig. 5 is a perspective view of the flask top in its final condition just before use.
Figure 6 is a sectional view illustrating one way in which the device may be used.
As shown, the exemplary embodiment of my invention comprises a primary container or flask I having a reinforced neck or mouth Id. Inserted into the mouth la of the flask is a generally cylindrical cup-like secondary container 2 made of aluminum or similar frangible or easily puncturable material and having a flange 2a seated against the top surface of the flask neck Ia, with the preferable interposal of a rubber or other flexible ring it therebetween. overlying the flange 2a of the cup-container is a deformable disc or diaphragm 4 made of natural or synthetic rubberor the like, and a cap 3 is clamped about the peripheral margin of the diaphragm 4 to secure the underlying elements flrmly'to the bottleneck, by a crimped portion 3" as shown, or by any other suitable means. The cap 3 is provided with a central opening to through which the central area of the diaphragm 4 is apparent, as more clearly shown in Fig. 2. The deformable diaphragm 4 together with the cap 3 forms a tight seal for the container. Under the diaphragm 4 and projecting down into the bottom of the cup 2 is the perforator member 5, now to b described.
The perforator member 5 (see Figs. 3 and 4) is of tubular shape, being produced from a flat plate in the general form of a shield (Fig. 4) rolled into an open tube with its adjacent longitudinal side edges 6 spaced from each other by an amount equivalent to about one fifth or so of the circumference of the tube. Projecting from the outer side of the tube are a number of spaced bosses or projections 1. The lower edge 8 of the tube is formed with a sharp point 9 tapering upwards gradually and merging with the vertical edges 6 through a progressive are 10. This tubular perforator member is inserted into the cup-like container 2 under a slight resilient pressure and over it is fitted a cap H formed with 'a central aperture [2 wide enough to allow insertion of a suitable pointed tool, such as a pencil. It will be understood that, with the outer cover l4 removed (Fig. 2), it is possible in this way to exert pressure through the diaphragm 4 and the cap ll upon the perforator 5 in the direction of the arrow F. The tapered shape of the lower end of the perforator is such that it gradually punctures the bottom of the cup-like secondary container 2 so that the entire contents thereof is gradually emptied into the primary container or flask i.
As illustrated in Figs. 1 and 5, the protecting outer cover l4 crimped about the neck of the flask is preferably provided with a breakable strip l5 which is torn off to remove the cap M. Preferably also, a reinforcing disc I 6 (Fig. l) is interposed between the top of the protecting cap or cover l'4 and the'cap 3 for further protection of the diaphragm 4 and the underlying perforator member 5.
' In preparing the assembly for use, the flask I is first filled with the desired quantity of the first of the two ingredients of the desired mixture, for instance a liquid solvent or a serum. The perforator member 5 with its apertured cap H is inserted into the cup 2 withthe seal ring 13 fitted under the flange of said cup. Theresulting unit including cup 2, seal ring 13, perforator 5 and cap H is next inserted into the neck of the flask i and the corresponding amount of the otherof the two ingredients, e. g. pulverulent penicillin, is introduced into the cup 2 through theaperture in cap i I.
The outer cover 14, protective disc l5, cap 3 and deformable diaphragm tar-reassembled separately to form a unit, and this unit is fitted 'over the neck of the composite container-filled as described in the preceding paragraph, and the skirts of the cap 3 and outer cover 14 are crimped around the upper reinforcement la of the neck of "the flask, by any known means such as with a rolleror rubber ring-type bottle capping machine.
The resulting composite container assembly may be preserved in this state for an indefinite period.
When it is desired to make use of its contents, the cover [4 is removed by tearing off the strip l5 (Fig. 5) whereupon the protecting disc i6 falls off. The container at this stage (Fig. 2) still remains sealed by the cap 3 and the rubber diaphragm 4 which protrudes visibly through the aperture 3a in the cap 3. With a pencil or other suitable means, a firm pressure is exerted upon the .perforator cap ll through the diaphragm 4 the resiliency-of which allows the perforator member 5 to be forced down with its lower edge '8 cutting through the bottom of cup container 2. Because of the open space defined between the adjacent longitudinal edges 6 of the perforator tube, the bottom of the cup 2 is not cut out entirely and will not therefore drop into the flask 1.. "Moreover,
the projections l frictionally engage the side walls of the cup 2 due to the resiliency of the perforator and prevent the perforator 5 from dropping out of the cup. The powder substance contained in the cup 2 drops into the bottom of the flask I and mixes with the liquid contained therein. The flask may be shaken to facilitate this mixing.
To use the resulting mixture, the mixture may be drawn out of the bottom of the flask without having to remove the cap 3 and diaphragm 4, by means of suitable aspirating means such as a hypodermic syringe i! and a needle l8 or trocar inserted through the centre of the rubber diaphragm 4, or in other suitable ways.
