CONTAINER AN D APPLICATOR Application filed m 29, 1932. Serial no. 625,714.

The solutions for which said device can advantageousl be employed comprise antiseptics, like io e, mercurochrome, peroxlde, potassium permanganate, carbolic acid, etc., or it may be a caute like a silver nitrate solution and similar (3 emicals which easily would stain the hands of the perator or other objects if too copiousl dispensed. The device is also very u'sefi il to contain highly volatile liquids like sulphuric ether or a solution of collodion, or hygroscopic or efflorescent liquids. It isobvious, however, that a practical application of my combined contamer anda licator is not necessarily confined to medicinal or sanitary purposes only, but that its peculiar advantages may be realized also for other and diverse purposes, for example to apply perfume in discrete quantities to objects, or to apply stain removing media, like benzene, carbon-tetrachloride, J avelle water, ink eradicators, etc., to a limited area or the like, and such and similar applications, therefore, would fall within the scope of my claims.

The first and main purpose of my invention, however, is .to rovide a combined bottle and .applicator w ich above all other features can be kept surgically clean.

A second object, concurrent with the first one, is to provide a container which does not need to be closed by a cork or stopper inserted into the dispensing orifice, as suchcorks or plugs can easily transplant germs from the i outside by direct contact and conveyance into the container. 7 v A third object is to provide a sanitary container which despite the just mentioned absence of an inser plug or cork, can, nevertheless, be closed airtight so that no contami nation by dust, germs or bacteria from. the

outside can reach the contents while the de-' vice is stored away. y A fourth object is to provide an applicator which needs no dipping or applicator rodwhich often is iiabie to transfer dust or. cotton lint or even shreds from bandages or wounds into the interior of the container.

A fifth object subservient to the last named is to provide an applicator which is directly applied to the spot to be medicated where- 55.

upon it may be sterilized by any convenient method while still in the inverted position.

Asixth object concurrent with the objects ust mentioned, isan applicator which immediately before and after use may be sterilized so by drawing the apertured end of it through a flame.

A seventh object is to providea container which on account of its peculiar construction,

offers a fair guarantee against refilling and therewith, against 'adulteration of' its original contents.

An eighthvobject is to provide a. container which due to its abovermentioned special construction, prevents accidental spilling or waste of the contents.

A ninth object, is to provide an applicator which must directly touch the spot to be medicated before it dispenses its liquid con- 7 tents.

A tenth object is to provide an applicator which when used will release the medicating or active fluid only in drops or restricted quantities, guaranteeing, therefore, an economical application and prevention of waste.

Other objects encompassed by or concurrent with the above, will become obvious from the more detailed description and illustration by the attached drawing in which:

Figure 1 is an elevation, partly in section 3 1 of a combined container and a plicator, made according to the principles 0 my invention. Figure 2 is a similar elevational view, also partly in section, illustrating a modified form W of the invention.

Figure 3 isa cross sectional view taken on line 3-3 of Figure2. at an emerged scale. a

Figure 4 is an elevational cross section through a cap for the applicator tip, show ing at the same time a form modified from the former ones. The figureis also drawn on an enlarged scale.

Similar characters denote similar parts throughout the difierent views.

' Referring more ind m {myths m Zoe tions shown, 10 designates the main body of the container. This has preferably the general form of a small bottle or flask, having an elongated conical neck 11 with a moderate contraction 12 beneath it.

Modifications of this general form, however, are entirely within the compass of the invention. For instance, a device of the character described and destined for a chemical or bacteriological laboratory ma in its lower portion convenientlyhave the iameter and general shape of a test tube so that it can be stored away on a rack adapted to hold test tubes. Or if the dev'ce is adapted for use as a toilet article or ladies boudoir, it may have any desired ornamental shape, as far as its main body is concerned. Also, the

' material of which it is made, may vary a great deal, according to the purpose, price, etc. It may be made of glass, wood or metal, especially such material which is not attacked by or does not enter into chemical combination with the fluid contents, (for example a lead flask would be suitable for fluoric acid, used for glass etching) porcelain, fibre, hard rubber or a cellulose or phenol condensation product may also be used, in fact any suitable and incompressible substance may be employed.

The conical neck is drawn out to a roundedofl tip 13 with a small hole 14 in it. This aperture must be ofsujch minute size, that the fluid contents under ordinary barometric pressure do not run out spontaneously by gravity when the bottle or container is re versed, but are held back within the container by capillary attraction. Yet, the size of the opening will be slightly greater for fluids having greater viscosity in proportion to this quality. When, however, the tip of the conical neck, which serves as an applicator, is dabbed upon or rubbed over a surface, the liquid will be drawn from the container by adhesion and will continue to flow out in a scant .driblet as long as the rubbing con- The bottle is originally filled by any convenient method known to those skilled in the art, preferably by the vacuum method, but as no special claim is made regarding the method of original filling, this is not described in detail. It is, however, clear that the container when empty cannot be refilled like an ordinary bottle and also that, while in use, it cannot very well be tampered with in thinnin or adulterating the contents, unless a specia apparatus for fraudulent purposes is emplo ed. 1

It is rthermore evident that all other objects listed .in the premises are fulfilled in an eflicientand inexpensive way. If the applicator be made of glass or even metal or porcelain, it may be sterilized by drawing through a flame.

How the third mentioned object LS attained, however, remains .to be described hereafter.

As shown in Figure 1, a ca 16 is provided which tightly fits the conica neck 11 of the applicator by a conical recess 17. If both, the ca and the applicator are made of glass, they s ould'advantageously be ound to an airtight fit. The interior of t e cap, however, leaves a clearance 18 over the applicaer to plicator is provided which makes the locking of the cap still more secure. In addition, the cap may be ound or cast in such relation to the app icator that when the ultimate end 20a of the conical thread 20 is engaged, the inner mantle 17a of the cap just fits the conical outer surface 11a of the applicator.

In the modified construction, illustrated in I Figure 2, the same elements as described in connection with Fi ure 1 are is beaded, i. e. the conical surface just below rovided. In addition thereto, t e tip of t e applicator the rounded off end is contracted as shown at 21 and the cap which is made in the form of a thimble, closely fitting over the conical neck of the applicator, has a correspondin contraction 22 which may resilientl be ipped over the beaded tip so as to the mouth of the container against the outer atmosphere. This beaded extremity or applicator may be hollow, as-shown in Figure 2, or it may be a solid head with the hole drilled through it. v

Another feasible modification of the a plicator shape which would prove especial y. handy in dental work, for IDStQ DCQ for the local application of cocaine, would consist in a curved elongation of the neck (not shown) so that one could apply the tip to narrow and confined places. While only two preferred forms of execution of the invention are shown, it is, how-, ever, to be understood that the Invention is not confined to these forms and that the drawing, therefore is to be considered as illustrative only, not as restrictive, and that many modifications and changes are possible without deviating from the general prineiples of the invention. The scope of the invention,

therefore, should be judged rather by the following claim.

Iclaim: K A combined liquid container'and applica torhaving a single restricted normally open orifice adapted to retain the liquid contents by capillary attraction and barometric pressure when the container is inverted and to permit a slow discharge of the li uid by adhesion when said orifice is broug t into contact with a surface underneath.

In testimony whereof I aifix my signature.

JULIUS FRIED.
