Oct. 19, 1954 J. L. JONES DISPOSABLE APPLICATOR Filed Oct. 18, 1952 IN N TOR.

Patented Oct. 19, 1954 UNITED STATES PATENT OFFICE DISPOSABLE APPLICA'DOR John Leslie Jones, Los Angeles, Calif.

Application October 18, 1952, Serial No. 315,475

13 Claims. 1

This invention relates to a new and useful device for applying compositions of matter to body cavities.

An object of this invention is to provide a compact sanitary disposable applicator for the treatment of body cavities with a stored viscous fluid medicament. Another object of this invention is to provide a sanitary inexpensive disposable applicator for the treatment of mammalian vagina with a composition of matter. Another object of this invention is to provide a short, easily carried, applicator for the treatment of body cavities with compositions of matter. Another object of this invention is to provide a compact, hygienic, disposable applicator for the treatment of a human vagina with a medicament. Further objects and advantages of this invention will become apparent in the following description, to be read in connection with the accompanying drawing.

Figure l. is an elevational view of my applicator embodying one form of my invention.

Figure 2 is an enlarged end View of my applicator looking from the right hand side of Figure 1 to the left.

Figure 3 is an enlarged elevational sectional view thereof, taken through 33 of Figure 1.

Figure 4 is an enlarged elevational sectional view of my invention in which the applicator is now prepared for insertion into a body cavity.

Referring to Figure 1, a rigid circular tubular form i of suitable uniform length and diameter is formed of thin wall paper stock. Coaxially located within tube i is a second thin wall circular rigid tubular plunger 2 of suitable length and whose external diameter is such as to form an easily telescoping pair. The end 5 of the plunger 2, extending a fingertip distance from tube 5, is pleatedly compressed to form a terminus easily grasped by fingertips of the user. A closure 3 for the applicator comprises a thin metal foil tape, coated with a pressure sensitive solvent resistant adhesive, which is applied in tightly, partially overlapped, turns wrapped circumferentially around the discharge end I!) of the applicator and the unsupported section of the foil tape is crimped together at the adhesive surfaces and twisted to form a non-raveling fluid tight closure. A paper tab t is amxed to the end of the foil tape to provide a means for easily detaching the tape.

The end view of the applicator in Figure 2 illustrates the multiple layers in the construction. The rigid circular tubular form I is tightly wrapped with one turn of a thin cellophane base pressure sensitive base adhesive tape 6. The cellophane tape 6 is wrapped with more than one turn of a thin metal foil tape having a pressure sensitive adhesive backing adhering to the exterior of the cellophane tape 6. A paper tab 4 is affixed to the end of the foil tape by attachment to the pressure sensitive adhesive backing, providing a tab 4 for the loosening and removal of the closure 3. The pleatedly compressed end 5 of the plunger 2 is shown in end view. Four pleats are shown and a plurality of pleats may be provided.

Referring to Figure 3, the rigid circular tubular form i is shown in telescoped relationship to the rigid circular tubular plunger 2, the crushable thin wall container "5 being concentrically located within and at one end of tube I. The terminal wall II of the container 1 is stretched and folded over the outside wall of the tube l and secured thereto by an overlapping turn of thin cellophane base pressure sensitive adhesive tape 6. The outside diameter of the container I is constructed to facilitate an easily slidable relationship between the container l, the open end 8 of tube 2 and the tube i. The closure 3 for discharge end it of the applicator is selected from the class of thin metal foil tapes having a pressure sensitive adhesive backing adhering to the exterior surface of the tape 6, adhesive being resistant to the action of the medicament 9.

Referring to Figure l, the applicator is shown prepared for insertion in a body cavity, the telescoping plunger 2 is shown in the inverted relationship with the tube I, the pleated compressed tip '5 being in proximity to the closed end of the container 1 and the end 8 of the tube 2 providing a handle for telescoping motion of tube 2 within tube i to discharge the medicament 9.

The term, fluid resistant erushable container is used to designate erushable containers made of thin, flexible materials resistant to the penetration of fluid compositions which are stored in the crushable containers, said fluid compositions being intended for use in the treatment of body cavities. Many of the fluid compositions contain water as an important component; there fore, the crushable containers for such compositions should be water resistant. Many of the fluid compositions contain other fluid organic materials as components; containers for such composition should be resistant to the penetration of such fluid organic components.

Examples of materials which may be used to form suitably shaped crushable, water-resistant containers are listed in Table I.

Table I Natural rubber Polyethylene resin Synthetic rubbers Butyl methacrylate resin Methyl acrylate resin P'olytrifluoromonochloroethylene resin Examples of materials which may be used to form suitably shaped crushable containers resistant to other fluid organic compositions of matter are listed as follows:.

Table II Neoprene rubber Vinyl chloride-vinyl acetate copolymer resin Polyvinyl alcohol plasticized resin Polytrifiuoromonochloroethylene resin The design of a vaginal applicator is subject to certain physical size requirements. The volume of the crushable container is that required to hold the desired volume of medicament.

It is desirable to make a device for application of a single dose of a medicament to a body cavity. It is also desirable that the device be inexpensive in order to justify discarding the device after a single use. It is good hygienic practice to prepare such devices and load them with a desired medicament in a factory Where high sanitary standards can be rigidly maintained during large quantity production.

In the use of my invention the embodiment illustrated by Figure I is manufactured and loaded with a desired medicament at a factory, capped and sold in multiple units in a single retail package. For use, the inner telescoping tube 2 is grasped at the pleated compressed tip 5 and pulled out from the outer telescoping tube l. The tube 2 is then reversed in direction and inserted in the outer tube 1, the pleated compressed tip 5 being pushed adjacent to the closed end of the crushable container I, as illustrated in Figure 3. The foil-pressure sensitive adhesive closure 3 is torn from the discharge end N3 of the applicator by the tab 4. The opened applicator containing the medicament 9 is inserted to the desired depth in a body cavity utilizing the tube l and the end 8 of the tube 2 as handles. The medicament 9 is discharged into the body cavity by exerting a crushing action on the bag 1 by telescoping the tube 2 within tube I.

Having now described and illustrated one form of my invention, I wish to be understood that my invention is not to be limited to the specific form or arrangement of parts hereby described and shown.
