Maurice N. Durand, Ridly Park, Pa. Application April 26, 1934, Serial No. 722,547

1 Claim.

My invention relates to a novel dropper, intended for all the various uses to which it may be adapted and believed to have wide application both as a time-saving dispenser and as a safe and effective nasal applicator.

A purpose of the invention is to provide a unitary barrel with two dispensing ends, one for each nostril and thus adapted to dispense drops or the like into both nostrils at once.

A further purpose is to provide a dropper with a safety feature, whereby even a child or a highly nervous patient may use it as a nasal dropper, without risk of inserting a dispensing end too far into a nostril.

A further purpose is to facilitate measurements of medicine by drops.

Further purposes will appear in the specification and in the claim.

I have shown a form of my invention which is practical and eificient in operation and which well illustrates the principles involved.

Figure 1 is a perspective view illustrating my dropper in use as a nasal applicator.

Figure 2 is a vertical elevation in part section, showing the applicator with its delivery ends dipping into a charging bottle.

Figure 3 is an enlarged scale longitudinal section of the applicator of Figures 1 and 2.

Like numerals refer to like parts in all figures.

Describing in illustration and not in limitation and referring to the drawing:

Considerable difficulty has been experienced in nasal application of medicine, generally called drops to children because of the restlessness and nervousness of the children, making it at times difiicult enough to apply the drops to one nostril and in such cases always additionally difficult to apply to the second nostril. My invention has been directed primarily to overcoming this difficulty, (and at the' same time protecting from excessive insertion of the dropper within the nostrils) by supplying means for applying the drops to both nostrils under the more favorable circumstances attending the first application. A quick, convenient and reliable applicator is provided for all nasal purposes.

In the illustrated form, my dropper includes a suitable bulb 5 of rubber or like material and a tubular body 6, as of glass.

The body comprises a unitary barrel 'l'and branching dispensing ends 8 and 9, with the bulb mounted on the large end of the barrel in the usual way, preferably by stretching the bulb 5 so that it engages the barrel 7 beyond a bead 10.

I most desirably make the dispensing ends 8 and 9 alike, and interiorly dimension them so that the ends dispense drops at substantially the same rates.

Doses of specific numbers of drops may be counted more quickly and easily than with a single outlet dropper of the prior art, since both the requisite time and the number of drops to be counted are cut in half by use of the double dropper.

I anticipate one of the wide applications of my dropper will be in dispensing drops into the nose and I therefore dimension the dispensing ends 8 and 9 for best adaptation to this service.

I space the relatively forking outlet ends prop erly so that they may be inserted simultaneously into both nostrils and I make the lengths of the ends such that these ends cannot be inserted too far into the nostrils, whether one or both ends are being inserted at a time, any undue insertion being prevented by the body portion at 11 between the forking ends engaging the nose at the nostril inlet. This is a safety feature particularly desirable when the dropper is for use by children or by nervous patients.

It will be understood that a user may close either dispensing outlet 8 or 9 when desiring to use the other outlet alone, such change conveniently involving merely placing a finger over the outlet to be closed.

One of the advantages of the invention lies in the fact that, since my device is an article of manufacture and is intended normally to be dipped into a container holding liquid to be inserted, the user will be able to fill the two parts of the tube uniformly without any difficulty and can check by the view through the glass after filling and before use.

In view of my invention and disclosure variations and modifications to suit individual whim or particular need will doubtless become evident to others skilled in the art to obtain all or part of the benefits of my invention without copying the structure shown, and I therefore claim all such in so far as they fall within the spirit and scope of my invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

As an article of manufacture, a two-piece dropper comprising a rubber bulb and a glass barrel with which the bulb connects, the barrel having a plurality of dispensing ends forking therefrom and integral therewith adapted to be filled through the ends when they are dipped in the liquid to be dropped and to give a view of the extent of filling through the glass.-
