FIG.5

FIG l PACKAGES ENABLING THE EXTEMPORANEOUS PREPARATION OF SUSPENSIONS OR STERILE SOLUTIONS This invention relates to packagesenabling the extemporaneous preparation of suspensions or sterile solutions.

It is already known, especially for enabling the preparation at the instant of use, of ophthalmic drops, to confine the lyophilic material and the liquid to be mixed, separately, the first in a flask and the second in an ampoule, the preparation consisting of opening the flask, decanting therein the contents of the ampoule, and mixing the whole, after having-recorked the flask with a dropper subsequently serving for delivery of the drops.

It is manifest that such a procedure does not permit proper regard to be had for desirable aseptic conditions. Moreover, the operator is compelled to carry out a large number of operations of which each may involve a mistake or a difficulty.

The same holds true in the preparation 'of certain antibiotics for which it is first necessary to inject a liquid into a flask by means of a syringe, then to agitate the flask and to withdraw therefrom the solution or suspension by means of the syringe before injecting the patient, generally after having changed the needle.

The primary object of the invention is to simplify these preparations while paying proper regard to the usual conditions of asepsis.

The present invention is a package comprising two flasks of which at least one is of a flexible material and which are adapted to contain one a liquid and the other a solid product to be dissolved in or put into suspension in said liquid at the time of use, stopper means on each flask and means for temporarily putting the interiors of the two flasks into communication with one another through at least one part of said stopper means, and in which the passage of the liquid from its flask to that of the solid product and the return of the solution or of the suspension to the flask for the liquid may be effected by manual deformation of at least one of the flasks.

This package enables there to be obtained a preparation the sterility of which is perfectly maintained both in use and in keeping in stock.

In a preferred form of the invention, the stopper means on one of the flasks makes up at least partially a device for perforating the stopper means on the other flask.

The invention will be better understood on reading the following description in conjunction with the accompanying drawings which illustrate, by way of example, embodiments of the invention, and in which:

FIG. 1 is a sectional elevation ofa package according to a first embodiment of the invention, in the condition before the two flasks have been put into communication with one another;

FIG. 2 is an exploded sectional elevation of the package shown in FIG. 1;

FIG. 3 is a sectional elevation ofa package according to a second embodiment of the invention in the condition before the two flasks have been put into communication with one another;

FIG. 4 is a sectional elevation of a package according to a third embodiment of the invention in the condition after the two flasks have been put into communication with one another;

FIG. 5 is an exploded sectional elevation of the package shown in FIG. 4, the stopper means and the cover being in the condition before the two flasks have been put into communication with one another; and

FIG. 6 is a sectional elevation of a modified plug for the package shown in FIGS. 4 and 5.

The package of FIGS. 1 and 2 is made up mainly by two flasks l and 2, the flask 1 containing a liquid and the flask 2 containing a solid product. The flask l at least is of a flexible material.

The flask 2 is stopped by a plug 3 of elastomeric material provided with a blind hole 4 located below a membrane 5. A ball 6 is held captive resiliently in the plug 3.

Above the plug is a washer 7 which is impervious to the liquid in the flask 1 and is formed by a polyethylene disk coated on one of its faces with a film of aluminium.

The washer 7 itself has thereabove an internallythreaded tubular casing 8, held in place on the plug 3 with the said washer by a collar 9 flanged around and taking support on the rim of the neck of the bottle 2.

The flask 1 is stopped by a dropper 10 the position of which in the neck of the bottle 1 is limited by a shoulder 11. The flask l is screwed by a thread 12 around its neck into the internally-threaded tubular casing 8.

In its position prior to use, the end of the dropper 10, which is open, rests on the impervious washer 7 and the relative position of the flask 1 dropper l0 assembly with respect to the flask 2 and to the parts which are united therewith is ensured by a tearable or rupturable spacing ring 13 accommodated in a peripheral space between a peripheral external flange 20 around the neck of the flask l, and the adjacent end of the tubular casing 8. As shown in FIGS. 1 "and 2, the spacing ring 13 supports a removable cover 14 which can subsequently be used for covering and protecting the lesser diameter end of the dropper 10.

The package of FIGS. 1 and 2 is used as follows:

the spacer ring 13 is torn and removed,

the flask 1 is screwed into. the tubular casing 8, this occasioning successively puncturings of the washer 7 and of the membrane 5 by the end of the dropper l0 7 and the dropping into the flask of the ball 6 expelled from its seat,

deformation of the flask 1 brings about the passage of its contents into the flask 2,

by agitationof the package, the solution or the desired suspension is obtained. The ball 6 then plays the part of an agitator in the flask 2 and speeds up the obtaining of the preparation,

the package is then inverted and the preparation sucked into the flask l, which is thereafter separated (with its dropper 10) from the flask 2.

After the first use of the preparation, the dropper 10 is covered by the cover 14 detached from the spacer ring 13.

For the description of the embodiments of the invention shown firstly in FIGS. 3 and 4, and secondly in FIG. 5, parts similar to those already described with reference to FIGS. 1 and 2 are designated by the same references but provided with the indices 0 and b, respectively.

The package of FIG. 3 includes two flasks 1a and 2a whereof the former holds a perforating dropper 10a and the latter a plug 3a with a ball 6a, an impervious washer7a and an encasing ring 9a. The initial positioning of the flasks la and 2a is ensuredby a spacing ring 15 whichit isnecessary to tear inorder to enable successively the perforation of the washer 7a and that of the membrane 50 aswell as the dropping of the ball 6a into the receptacle 2a and the stepspof transferring the products, such as have been described with reference to FlGS. l and 2. V

The packageofFlGS. 4 and is made upmainly of.

two flaskslb and 2B whereof the former carries a dropper 1"0b closed at its end by a bulging 16 which can be cut off. The flask 2b is stopped by a plug 3b with a perferable membrane Shanda cover 17 kept on the flask 2b an encasing ring 9b. The cover 17 includes a hemispherical central part 18 which can be cut off just as can the bulged part.16 of the dropper.

In this package the flasks 1b and 2b are initially sepa- 7 rated. At the time of use, the bulged part 1 6 of the dropper 10b' and thehemispherical central part 18 of the cover 17 are cutoff along the respective dot-dash lines'x and y indic ated in FIGS. The extremity of the dropper 10b is then introduced into the remaining part of the cover 17, which ensures guidance of the dropper, and 'the latter pierces the perforable membrane 5b of the plug 3b. The package then being in the condition shown in FIG. 4, it is possible to proceed with the trans-1 fer of the liquid and then the preparation by dcforma tions under consideration; without thereby departing from the scope of the invention defined in the claims.
