Patented Apr. 13, 1937 UNITED STATES SYRINGE OR APPLICATOR Herman B. Lermer, Newark, N. J., assignor to Hygienic Tube & Container Company, Newark, N. J., a corporation of New Jersey Application March 3, 1936, Serial No. 66,779

1 Claim.

This invention relates to applicators for applying medicaments to body orifices in a simple and convenient manner, more effectively than has heretofore been possible.

One of the objects of the invention is to pr vide an exceedingly simple, inexpensive and practical device of the class specified, adapted to permit the application of a substantial, and if desired, a measured quantity of medicament.

Another object of the invention is to substitute for the heretofore commonly used materials, preferably but not necessarily, an unbreakable, flexible and preferably a transparent applicator formed of a material, a. cellulose product for instance, which will not be damaged when cleaned in hot water, or otherwise cleaned, and one which owing to its transparency, enables the user to positively see the substance pass out through the applicator tube.

A further object of the invention is to so form one end of the applicator tube that it will lend itself admirably well for releasably connecting the applicator tube to containers such as are extensively used for merchandising medicaments and jellies for feminine hygiene, which are made of yielding materials, so that the contained substances may be gradually forced out by pressing the sides of the container together.

A further object is the provision of a transparent tube having a piston slidably mounted therein for insuring the complete discharge of the entire contents of the tube.

These and other advantageous objects, which will later appear, are accomplished by the simple and practical construction and arrangement of parts hereinafter described and exhibited in the accompanying drawing, forming part hereof, and in which:

Fig. 1 is a sectional view of a medicament applicator embodying my invention,

Figs. 2 and 3 are similar views, of tubes embodying a further modified form of the invention, and

Fig. 4 is a fragmentary sectional view of a further modification of the invention.

Referring to the drawing, there is shown a device for applying substances to body orifices, such as the anal canal or the vagina, comprising a tube I preferably made of a flexible, transparent, non-breakable material; however, it should be noted that the tube can be made of any suitable material, for noting the contents thereof, if desired.

Referring to Figs. 1 and 3, at each end there- 5 of, the tube I is formed of a transparent mate'- rial as above described, and the rod 4 with its piston 5 is inserted in the tube so that it will slide freely therein. The ends of the tube are then bent inwardly to form the rounded ends 2 and the flanges 3 which prevents the rod and 5 piston from becoming separated from the tube.

In Fig. 2 is shown a slightly modified form of the invention in which the tube I is formed from a cellulose material or the like, preferably of a. slightly greater thickness than is necessary in 10 the device described in connection with Figs. 1 and 3. At each end of the tube internal shoulders I are provided upon which rest tight fitting ferrules 8 which project slightly inwardly from the inner walls of the tube, thereby providing 15 stops to limit the movement of the slidably mounted piston.

The inturned flange 3 at the upper end of the tube I forms a suitable bearing for the rod 4 which has integrally or otherwise attached thereto a 20 suitable knob 6 by means of which the, piston 5 and rod 4 can be'moved lengthwise of the tube. Obviously, in applying or extruding the substance, the piston is forced to a position near the end of the tube, thereby causing the sub- 25 stance to be discharged therefrom.

In order that smaller quantities may be definitely applied with the same device, the tube may be graduated throughout its length.

It will be noted that the piston 5 is a short 30 distance from the free end of the rod I so that when the rod is moved forward almost its entire length, the free end I I will pass into the open ends ll) of the tube I, discharging any of the substance ,which might accumulate, thereby expellingthe 35 entire contents from the device.

, InFig. 3 is shown another modified form of the invention in which the tube I has secured thereto in any desired or convenient manner a bulbous member 9, or whichmay be formed integral 40 made of hard rubber or other suitable material; 50

The tip 9 has its bore formed with a shoulder engaging the end of tube I, so that the inner wall of tube I is flush with the inner wall of the tip 9' as shown in the drawing. A piston 5 is slidably mounted in tube I, the piston being attached to ,55

a rod 4, which is of sufllcient length to enable the piston i'- to be moved entirely through tube and tip 9' so that all substances can be forced out of the tube and tip entirely.

The foregoing disclosure is to be regarded as descriptive and illustrative only and not as restrictive or limitative of the invention, of which obviously an embodiment may be constructed including many modifications without departing noted in the appended claim.

aovmve Having thus described my invention, what I claim as new and desire-to secure by Letters Pat- 1 the ends thereof turned inwardly back along and parallel to the inner wall 01 the tube to provide flanges serving as stops to limit the movements of the rod.
