DIRECTIONAL APPLIcAToR Filed sept. 3, 196s INVENTOR.

United States Patent "Ice 3,148,806 DIRECTIGNAL APPLICATR Philip Meshberg, 290 Euclid Ave., Fairiieid, Conn. Filed Sept. 3, 1963, Ser. No. 306,133 10 Claims. (Cl. 222-394) The present invention relates to a simple and inexpensive directional applicator for aerosol packages for use in dispensing the material therefrom.

The present invention is particularly useful in the dispensing of pharmaceuticals and the like materials, and directing the same into specific locations, particularly within body cavities.

Heretofore, eiiorts have been made to provide directional applicators but these have been complicated structures involving unique valve assemblies and pivotal constructions in which the applicator is movable between an inoperative position and a fixed dispensing position in which the bore therein must be aligned with the bore in a button. These have been costly and have been on the whole not entirely satisfactory due to leakage and other factors.

The present invention overcomes these difficulties by providing a novel, yet simple directional applicator adapted to have a standard button and to be mounted on the aerosol package to which various types and shapes of applicator tubes can be readily assembled, as may be required by the particular requirements, for directing the discharge of the dispensed material through a wide range of positions with respect to the package.

A feature of the invention resides in the simplicity of the device and ease with which it is manufactured and operated.

Another feature of the device resides in the fact that the directional applicator can have means provided thereon for preventing inadvertent operation of the valve during storage or shipment or otherwise handling of the aerosol container.

A still further feature of the directional dispenser resides in the arrangement whereby the applicator tube can be located in adjacent but spaced relation to the side of the container so as to be readily packaged in packing containers and shipped without requiring any substantial excess space.

Other features and advantages of the invention will be apparent from the specification and claims when considered in connection with the accompanying drawings in which:

FIGURE 1 is a view of the directional applicator, in disassembled relation, for a bottle package.

FIG. 2 shows the applicator in dispensing position with the normal inoperative position shown in dash lines.

FIG. 3 is a view similar to FIG. 1 with the applicator assembled and in position on the bottle.

FIG. 4 is a sectional view of the applicator as applied to a can type container.

FIG. 5 is a view of another form of applicator with a separate stop applied.

FIG. 6 is a side view similar to FIG. 5 showing the stop in position.

As shown in the drawings, the novel directional applicator comprises two elements-a button 10 and a directional applicator tube 11. The button, as shown in FIGS. 1 and 3, is preferably molded from thermoplastic material and has a bore 12 adapted to receive the end of a projecting reciprocable valve stem 13 of a valve means (not shown). The valve stem can be of any desired type having a discharge passage therein. For example, such a valve stem is shown in my patent, No. 2,721,010. The button has a passage 14 therein communicating with the end of the stem and with a recess 15 opening on the 3,148,805 Patented Sept. 15, 1964 surface of the button. While the recess may be of various shapes and located in any desired position, it is herein illustrated as a cylindrical recess opening on the side surface of the button with the passage 14 being axially disposed in the bottom thereof. The applicator tube 11 is provided with a cylindrical end portion 16 which is adapted to snugly fit into and be removably mounted in the cylindrical recess with the tube projecting therefrom and has a bore 17 extending therethrough, which bore is in communication with the passage 14 in the button so as to direct the aerosol material from the bottle through the tube to direct it and apply it in a precise location.

While the tube may take various shapes, in the herein illustrated form of the invention, as shown in FIGS. 1-3, the tube is an L-shaped tube having the cylindrical portion 16 formed at the end of the base 18 of the L and the discharge passage extending therethrough and along the stem 19 of the L to the end thereof. The end 16 of the tube is rotatably mounted in the recess 15 so that the tube can be moved relatively to the package to direct the material from a large number of positions. Since the passage 14 is always in communication with the bore 17 in all positions of adjustment of the tube, the need for aligning the passages and the precise positioning of the tube to effect satisfactory operation thereof is eliminated.

Preferably the base of the L is of such a length that the stem of the L, as shown in FIGS. 3 and 4, when the tube is in a normally inoperative position, lies adjacent to and parallel with the side of a bottle 20 (FIG. l) or a can 21 (FIG. 4), whichever may be used inthe package, so that it can be readily packaged in a cardboard carton or otherwise handled with a minimum of danger.

In the form of the invention shown in FIGS. 1-4, the tube is provided with a blocking member 22 formed integrally as a rib 23 lying in the angle of the base and stem of the L-shaped applicator tube and adapted, when the applicator is in said normal position on the button, to engage the top of the package and prevent operation of the reciprocating valve stem to inadvertently discharge material. The stop, however, as shown in FIG. 2, is moved out of blocking position when the applicator tube is moved to a dispensing position for directionally applying the material.

The applicator as shown in FIG. 2 has been moved to a right angle position. However, since the applicator rotates in the cylindrical recess and is always in commnication with the passage in the button, it can be moved to any position within approximately 340 and is dispensed therefrom when tnger pressure is applied to the button as shown in FIG. 2.

While the directional applicator tube may be made of various materials, it is at present preferred to form it of thermoplastic material. In the form of the invention as shown in FIGS. 1 to 4, it is molded as a unitary structure.

In another form of the invention, an applicator tube 11a is formed from an extruded tube of thermoplastic material which is bent as shown in FIG. 5, and has its cylindrical end portion 16a rotatable in the cylindrical recess or socket 15 with the bore 17a extending therethrough and forming a structure which can be readily fabricated in an inexpensive manner. In this form of the invention, if desired, a stop 22a can be molded as a separate element to be assembled therewith and Secured to the tube, as shown in FIGS. 5 and 6, in position to engage the package and prevent inadvertent operation of the button in the manner of the integral stop block of FIGS. l-4.

In some cases where there is danger of contamination of the directional applicator tube during the use thereof, the tubes can be made of disposable material, such as paper, cardboard, or inexpensive plastic material, and

3 can be readily removed and replaced simply by withdrawing the end of the tube from the cylindrical recess and inserting the new tube.

It will be seen therefore that the present invention provides a simple and highly eihcient directional applicator in which a standard button can be employed with a plurality of types of applicator tubes (which can be readily removed or replaced) depending upon the use to which the directional applicator is intended. Since the recess in the button forms the rotatable mount for the tube and the bore in the tube is always in communication with the passage in the button, the tube can be moved to many dispensing positions with respect to the package without requiring expensive pivot constructions or valving means therefor. Further, since the tube can be moved to a plurality of operative positions with respect to the package, the device can be used for most applications Without requiring the package to be inverted or tilted to a point wherein the usual clip tube in the package becomes ineffective.

Variations and modifications may be made within the scope of the claims and portions of the improvements may be used without others.
