SHEET 2 OF 2 INVENTOR MARCEL o cHiquiAR ARiAs AQMM BACKGROUND OF THE INVENTION This invention relates to disposable prophylactic articles and more particularly it relates to improvements in disposable, unbreakable prophylactic containers, as dosifyed devices for solutions, medicinal and similar products.

Currently, the prophylaxis or sterility of containers holding products, which if contaminated may cause serious problems to users. This is subject of special interest in the industrial field and the manufacturers of containers for these products have found, as a maximum novelty, the use of disposable containers, that is, once the containers have been used they cannot be employed or filled again.

However, up to the present, these disposable containers have not been completely satisfactory as far as prophylaxis is concerned, since many are produced for supplying several doses and after the employment of the first dose the sterility is lost, and in other instances, during filling or when users open these containers, they may spill the contents or contamination risks may be involved, since some require additional tools for opening same, such as scissors, saws, punches and the like.

Among the products liable to be placed in this type of containers there is a large variety such as cleaning and impregnating solutions for medical or similar products.

As an embodiment of this conventional disposable prophylactic articles, the disposable syringe can be taken into account but up to the present same has not been employed as such, since the user generally will or can reuse it with the corresponding contamination risk.

BRIEF SUMMARY OF THE INVENTION Therefore, one object of this invention to provide a prophylactic, unbreakable dosifyed disposable container for contact lens solutions medical and similar products controlling its administration, without ofi'ering contamination risks nor possibility ofreutilization.

Another object of this invention is to provide, as a novelty, a syringe-container including the dosifyed solution.

Said syringe-container may be of the autodestructive type, after having been used.

The preferred embodiment of the invention comprises a syringe container including a cylinder of a rigid thermoplastic material integrally coupled at one of its ends to a center pivot slightly tapered towards one end which is sealed and includes a weakening or throttling in its cross-section. The cylinder is filled with an injectable dosifyed solution and it may include a longitudinal groove or weakening at the end of which is a knife attached to a flap supporting the piston or plunger. Thus upon breaking open the pivot and coupling the needle while sliding the piston or plunger, on the cylinder to inject the solution, the full length of the syringe will be broken, thereby avoiding the subsequent use of same.

These and other objects and advantages that are obtained in the practice of this invention will be better understood and appreciated on reading the following description that makes reference to the attached drawings of the preferred embodiments of the invention.

DETAILED DESCRIPTION OF THE DRAWING FIGURES FIG. 1 illustrates in a vertical elevation view the autodestructible syringe-container embodiment of the invention.

FIG. 2 illustrates in a fragmentary longitudinal section view of said syringe-container of the invention.

FIG. 3 is a detailed view illustrating how the pivot of the syringe-container of the invention is broken open.

FIG. 4 illustrates a view of the needle coupled on the pivot or noule of the syringe-containers of the invention.

FIG. 5 illustrates a view of the needle shield covering same.

FIG. 6 is a cross-section view on line 66 of FIG. 2.

DETAILED DESCRIPTION OF THE INVENTION The invention in the illustrated embodiment resides in an auto-destructible syringe-container that comprises a cylinder 19 of a rigid thermoplastic material integrally coupled at one of its ends to a pivot 20, slightly tapered towards its end 21, which is sealed and includes a weakness or throttling 22 in cross-section to readily break open same which thereby forms a frangible outlet including a tapered tip having a weakened cross-section.

Cylinder 19 is pre-filled with the injectable solution 23 in one dose form having longitudinally a weakening of halfgroove 24. At the end of the half-groove 24 there is a full groove 25 that passes through the wall of the cylinder wherein a knife 26 is placed that does not protrude from the cylinder of the syringe-container. The knife could be retracted a small distance until the rear part of the plunger 27 abuts against an inner stop 28 for the purpose of avoiding that the knife 26 gets off beyond the end of cylinder 19 from where the supporting ears 29 project normal to the axis of said cylinder.

This slight freedom of alternative movement of the plunger and the knife is useful for intravenous injections wherein checking of the proper position is required by means of a slight, retraction movement. The knife 26 is attached to one of the push rod or flaps 30 having cross-section in a manner similar to a cross, and flap 30 pushes the plunger 27 when pressure is exercised on the end push disk 31.

On breaking open pivot 20 through the weakening 22 and injecting the dose of the solution 23, the knife 26 runs along the weakening 24 cutting out longitudinally the syringe wall, positively avoiding the reutilization of same.

Although the invention has been shown and described particularly referring to several embodiments of same, it is to be expressly understood by those skilled in the art that the above mentioned and other changes in its manner and detail can be made without departing from the spirit and scope of the invention.

I claim:

1. A prophylactic, unbroken dosifyed disposable container for controlling the administration of products for contact lenses, medical and similar products, characterized by consisting of a cylinder integrally coupled at one of its ends to a frangible outlet including a tapered tip having a weakened cross-section for coupling injection needles and having at its other end a pair of integral supporting ears projecting normal to the axis of the cylinder and a piston or plunger coupled slidingly in the cylinder and being driven by means of a push disk through a rod, characterized in that the frangible outlet is sealed including a breakable throttling in its weakened cross-section and the cylinder being pre-filled with an injectable solution and in that it may be provided in its wall with an outer half-groove or weakening throughout its length, at one end of said weakening is located a full groove passing through the wall of the cylinder having located therein a knife that is attached to a flap of the rod supporting the piston.

2. A container according to claim 1, also characterized because the cylinder includes an inner stop that limits the backward stroke of the plunger or piston.

3. A container according to claim 1, also characterized in that the knife does not protrude from the cylinder and when the plunger reaches its inner stop the knife does not get off beyond the pair of supporting ears.

4. A container according to claim 1 wherein said container is a flexible material.

5. A container according to claim 1 wherein said container is of a rigid, resilient material.
