Claims
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.
Description
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 offering contamination risks nor
possibility of reutilization.
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
auto-destructible 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
nozzle 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 6--6 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 half-groove 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.
