ATTORNEY MEDICATOR WITH FRANGIBLE SEAL This application is a continuation-in-part of my application Ser. No. 877,639 filed Nov. 18, 1969, and now abandoned.

BACKGROUND OF THE INVENTION Single use articles such as paper gowns and linens, throw away syringes, hypodermic devices, medicament containers and the like, and disposable instrument parts, such as shields for entrance into various orifices in the body have found increasing utility in the medical arts. The advantages of such improvements are the reduction of equipment and labor costs for sterilizing such articles as well as the elimination of possible intercontamination due to resistant strains of bacteria or improper sterilization of such articles.

Although these articles solve many of the problems of the prior art, an area of possible contamination and handling cost remains in the transfer of medicament from the container to an applicator. Although single use containers for such purposes have been provided heretofore, the danger of contamination of the medicament during transfer to an applicator and the problem of handling expense and storage of separate items prevails in the art.

SUMMARY OF THE INVENTION This invention provides a single use medicament applicator and container which avoids the problems of the prior art by furnishing a combined throw-away article.

The invention also provides an improved medicament container which can be combined with various types of applicators.

The invention further provides an applicatorcontainer of the type described which can be manufactured at a minimum cost and which is simple to use.

In a preferred embodiment the invention comprises an applicator; a closed medicament container connected to the applicator and a seal between the container and the applicator frangible upon the application of lateral inward pressure thereto to release the medicament on to the applicator.

These and other objects and attendant advantages of this invention will become better understood by those skilled in the art by reference to the following detailed description when viewed in light of the accompanying drawings wherein like components throughout the figures thereof are indicated by like numerals and wherein:

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a sectional, elevational view of an applicator in accordance with the invention;

FIG. 2 is a view similar to FIG. 1 of another applicator in accordance with the invention;

FIG. 2a is a section on line 2a-2a of FIG. 2;

FIG. 3 is a view similar to FIG. I of yet another applicator in accordance with the invention; and

FIG. 4 is a view similar to FIG. I of still another applicator in accordance with the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment illustrated in FIG. 1 comprises an applicator, and a medicament container shown generally at I0 and II, respectively. The applicator 10 consists ofa tubular holder I2 and a fibrous wadding or liquid adsorbing mass 14 of cotton or like material. The holder may be fabricated of any material, relatively rigid or flexible, which is compatible with the medicament and the environment in which the device is to be used.

The container 1 1 comprises flexible walls 16 defining a chamber which can be urged inwardly upon the application of inwardly directed lateral force and an opening 18. A frangible seal 20 closes the opening 18 to retain or store a fluid medicament 22 in the container 1 l. The walls 16 are preferably formed of a molded flexible material compatible with the medicament and the environment in which the device is to be used such, for example, as high density polyethylene, polypropylene, polystyrene, polyvinylchloride or the like.

The seal 20 is formed of a frangible material preferably configured as a thin membrane. Thin films of plastic or aluminum foil which can be heat sealed to the container 11 have been found to be particularly suitable for this purpose. The frangible seal or thin membrane 20 may be formed of the same plastic composition as the walls 16 and the thinness of the plastic forming the seal 20 renders it frangible upon the application of inward bending forces to the side walls 16.

As can be seen by reference to the figure, the opening 18 is defined by an annular, intumed wall 24 to which the seal 20 is attached by heat seal, as described above or by adhesive or other suitable means as found desirable. The holder 12 is dimensioned to fit snugly around the outer periphery of the container 1 l and can be affixed thereto by adhesive, force fit or any other means found desirable. The holder 12 may be removably friction fitted to the container 11 if the use requirements thereof so dictate. The holder 12 and container 11 may be of any compatible cross-sectional configuration such, for example, as circular, rectangular or polyagonal as may be found suitable.

In FIG. 2 another embodiment in accordance with the invention is illustrated in which components thereof corresponding to like components of the embodiment of FIG. 1 are indicated by like numerals only of the next higher order.

The majority of the components of the embodiment of FIG. 2 are identical to those of FIG. 1 including the applicator formed as an open-ended barrel 112 interfitted to the container 11 I and containing a tiberous wadding 114.

In this embodiment the frangible seal is provided with one or more score lines 121 thereon as shown in FIG. 2a which score lines fonn lines of weakness or burst lines for the seal when inward force F is applied to the walls of the container 111.

In the embodiment of FIG. 3, where again components corresponding to those of the preceding Figures are indicated by like numerals of the next higher order, a variation in the joining structure between the applicator 210 and the container 211 is shown. In this embodiment, the wall 224 of the container forms an outturned flange 224 and a similar, coextensive out-turned flange 225 is formed on the bottom of the holder 212. The seal 220, coextensive with the aforedescribed flanges, is sandwiched between the flanges and the assembly is joined by adhesives, heat seal or other appropriate means.

It will be noted that outturned or the inturned flanges assist in protecting the frangible seal from inadvertent rupture as the inwardly directed force F to rupture the seal 220 must first overcome the rigidity of the flange.

The embodiment of FIG. 4 corresponds generally to that of FIG. 3 with the exception that the holder 212 thereof is eliminated and the applicator 310 comprises only the wadding 314 joined to the container by adhesion or other suitable means beneath the flange 324.

In use, the seal 20, 120, 220, or 320 is broken and the medicament is fed to the applicator portion for use. In the embodiments of FIGS. 1 through 4 this is accom plished by forming the containers 11, 211 and 311 of a flexible plastic material and the seals 20, 220,-and 320 of a material having a bursting strength less than the force which can be generated by compression of the container on the fluid contents thereof.

What has been set forth above is intended as exemplary to aid those skilled in the art in the practice of the invention.

What is new and desired to be protected by Letters Patent of the United States is:

What is claimed is:

1. A medicator comprising:

an applicator means;

a medicament container connected to said applicator means, said container having walls formed of a flexible material and being deformable upon the application of inwardly directed forces thereto;

a frangible seal between said container and said applicator means blocking communication therebetween, said seal having a bursting strength lower than the force which is generated thereagainst by compression of said container to inwardly deform said walls;

wherein said applicator means comprises a tubular holder with a fibrous wadding closing one end thereof, the other end of said holder communicating with said seal; and

wherein said applicator means is removably connected to said container.

2. A medicator in accordance with claim 1 wherein said frangible seal is provided with score lines to form lines of weakness for said seal.
