Abstract
Abstract A package for the extemporaneous preparation of suspensions or sterile solutions, comprises two flasks at least one of which is of a flexible material and which are adapted respectively to contain one a liquid and the other a solid product to be dissolved in or put into suspension in the liquid at the time of use. Each flask has associated therewith stopper means and the package includes means for temporarily putting the flask interiors into communication with one another through at least one part of said stopper means. Said at least one of the flasks is manually deformable to effect the passage of the liquid from its flask into the flask containing the solid product, and the return into said at least one of said flasks of the resultant solution or suspension.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
155 words
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 which is a selected member of the group consisting of substances dissolvable in and substances suspendible 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, said at least one of the flasks being manually deformable to effect the passage of the liquid from its flask into that of the solid product and the return of the solution or of the suspension to the flask for the liquid, said flasks are kept together in alignment and in readiness for the putting of their contents into communication with each other by spacing means which can be torn away.
Claim 2
Dependent Claim
155 words
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 which is a selected member of the group consisting of substances dissolvable in and substances suspendible 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, said at least one of the flasks being manually deformable to effect the passage of the liquid from its flask into that of the solid product and the return of the solution or of the suspension to the flask for the liquid, said flasks are kept together in alignment and in readiness for the putting of their contents into communication with each other by spacing means which can be torn away.
Claim 3
Dependent Claim
34 words
A package as set forth in claim 1, in which the stopper means on one of the flasks makes up at least partially a device for perforating the stopper means on the other flask.
Claim 4
Dependent Claim
35 words
A package as set forth in claim 2, in which said one of the flasks carries a dropper having a projecting end adapted for perforations of the stopper means of the other of the flasks.
Claim 5
Dependent Claim
49 words
A package as set forth in claim 3, in which the stopper means of said other of the flasks comprises a plug of elastomeric material held in the neck of the flask and having an axial bore stopped by means which can be overcome by said dropper projecting end.
Claim 6
Dependent Claim
20 words
A package as set forth in claim 4, in which said means which can be overcome is an ejectable ball.
Claim 7
Dependent Claim
20 words
A package as set forth in claim 4, in which said means which can be overcome is a perforable membrane.
Claim 8
Dependent Claim
25 words
A package as set forth in claim 4, in which said means which can be overcome consists of an ejectable ball and a perforable membrane.
Claim 9
Dependent Claim
40 words
A package as set forth in claim 7, in which the plug has thereabove a washer which is impervious to the liquid and is formed by a polyethylene disk coated on one of its faces with a film of aluminium.
Claim 10
Dependent Claim
60 words
A package as set forth in claim 4, in which said plug has thereabove a cover which includes a hemispherical central part located in alignment with said axial bore and which can be cut off at the time of use, said cover being retained on the plug by an encasing ring on the rim of the neck of the flask.
Claim 11
Dependent Claim
25 words
The package of claim 3 further including removable means for preventing the projecting end of said dropper from perforating the stopper of the other flask.
Claim 12
Dependent Claim
62 words
A package as set forth in claim 1, wherein one flask is adapted to be displaced relative to the other for putting the interiors of the two flasks into communication with one another, such displacement being under the guidance of an internally-threaded tubular casing carried by one of the flasks and into which is screwed a threaded neck of the other flask.
Claim 13
Dependent Claim
39 words
A package as set forth in claim 1 in which the flask containing the liquid carries a removable cover adapted to be detached from said spacing means and to replace the stopper means on the first flask once opened.
