United States Patent LIQUID DISPENSING CONTAINER Anthony J. Corraccio and Peter P. Spirito, Hartford, Conn.

Application April 3, 1953, Serial No. 346,611

3 Claims. (Cl. 15-105) This invention relates to liquid dispensing containers and more particularly to a container for holding, dispensing and applying a liquid, such as mucilage, stamp pad ink, or shoe polish, and especially for use in the metal working industry for applying oil as a coolant as well as a lubricant, the brush being used as an oil applicator and also for brushing metal chips from the cutter and the work piece.

It is among the objects of the invention to provide an improved liquid containing, dispensing and applying device including a spring bottom container having a neck, a spout releasably secured to the neck of the container and an applicator, such as a brush, secured to the spout and normally disposed in the container; which is effective to forcibly eject liquid from the container through the spout in response to pressure on the spring bottom of the container; in which the applicator may be made available for applying liquid to or spreading liquid on a Work surface by removing the spout and associated applicator from the container, the spout serving as a handle for the applicator when the spout and applicator are removed from the container; in which the applicator can be replaced whenever necessary or desired; and which is simple and durable in construction, economical to manufacture, effective and eflicient in use, and neat and attractive in appearance.

Other objects and advantages will become apparent from a consideration of the following description and the appended claims in conjunction with the accompanying drawing wherein:

Figure l is a top plan view of a liquid containing, dispensing and applying device illustrative of the invention;

Figure 2 is a side elevational view of the device with a portion broken away and shown in cross section to better illustrate the construction thereof;

Figure 3 is a cross sectional view on the line 3-3 of Figure 2;

Figure 4 is a fragmentary cross sectional View on an enlarged scale on the line 4-4 of Figure 1;

Figure 5 is a fragmentary cross sectional view on an enlarged scale on the line 55 of Figure l; and

Figure 6 is a perspective view of an applicator and spout assembly constituting an operative component of the device.

With continued reference to the drawing, the device comprises, in general, a spring bottom container 10, a tubular spout 11 detachably secured at one end to the container, an applicator 12 detachably secured at one end to the spout at the end of the spout secured to the container and normally disposed within the container, and a stopper 13 detachably mounted on the end of the spout remote from the applicator 12.

The container comprises a bell shaped side wall 15 having at its smaller end a neck formation 16 including an annular flange 17 extending inwardly of the smaller end of the side wall and provided interiorly thereof with a beveled surface 18 of frusto-conical shape having its larger end at the end of the annular flange disposed outwardly of the interior of the side wall, and its smaller end at the end of the annular flange disposed inwardly of the interior of the side wall 15. A spring bottom 19 is disposed in closing relationship to the larger end of the bell shaped side wall 15 and is marginally secured to the adjacent end edge of the side wall by a beaded over formation 20 on the bottom receiving the end portion of the side wall, the side Wall being provided at this end with a terminal bead 21 which assists in retaining the beaded over portion 20 of the spring bottom on the cor responding end portion of the side wall.

The spout 11 is tubular and tapered from one end to the other, having a restricted aperture 22 in its smaller end for dispensing liquid therefrom. A cap 24 is joined to the larger end of the spout 11 and includes a cylindrical portion 25 of a diameter somewhat greater than the dime ter of the larger end of the spout joined at one end to the larger end of the spout and an annular flange or boss portion 26 of larger diameter than the cylindrical portion 25 joined at one end to the end of the cylindrical portion remote from the spout 11 and having its end remote from the cylindrical portion 25 open. The annular flange portion 26 of the cap has its external surface 27 beveled to a frusto-conical shape corresponding to the frustoconical shape of the inner surface of the neck flange 17, and has its inner surface substantially cylindrical and provided with an annular groove 28 intermediate the length of this portion of the cap.

The neck flange 17 is provided with a pair of diametrically opposed bayonet slots 30 and 31 and the flange portion 26 of the cap 24 is provided with a pair of outwardly projecting pins 32 and 33 disposed at diametrically opposite locations therearound and engageable, one in each of the bayonet slots 30 and 31 to releasably secure the cap flange 26 in the neck flange 17 of the device.

The applicator 12 comprises a back 35 preferably formed of a somewhat elastic material, such as vulcanized rubber, of cylindrical shape received in the cap flange 26 and having a cylindrical outer surface in contact with the inner cylindrical surface of the cap flange. This back 35 has a peripheral bead engaged in the groove 28 in the inner surface of the cap flange to releasably secure the back in the cap flange, and a brush 36 comprising a plurality of bristle tufts disposed in side by side relationship to each other, is secured at one end in a centrally disposed aperture 37 in the brush back 35, the brush 36 having a length somewhat less than the distance from the neck flange 17 of the container to the spring bottom 19 of the container, as illustrated in Figure 2.

The brush back 35 is provided with a pair of diametrically opposite apertures 38 and 39 extending transversely therethrough and which constitute liquid passages placing the interior of the cylindrical portion 25 of the cap 24 and the interior or bore of the spout 11 in communication with the interior of the container 10.

The stopper 13 is illustrated as a substantially spherical body having a tapered recess therein receiving a portion of the spout 11 at the smaller end of the spout and closing the liquid dispensing orifice 22 in the smaller end of the spout when the device is not in use. Obviously, the stopper 13 is removed from the spout when it is desired to dispense liquid from the container 10 through the dispensing orifice 22 in the smaller end of the spout.

The device may be used for dispensing liquid from the dispensing orifice at the smaller end of the spout, in the manner indicated above, by first removing the stopper 13, tilting the device, so that the liquid in the container 10 will pass through the liquid passages 38 and 39 into the spout and then subjecting the spring bottom 19 of the container to external pressure to force the liquid from the container through the spout and forcibly eject the liquid through the dispensing orifice 22. In this manner, a desired amount of liquid can be dispensed onto the surface of a work piece to be treated. If it is desired to-spreadthe liquid on the surface of the work piece, the cap 24 is removed from the container neck 16 by first rotating the cap until the pins 32 and 33 are brought into alignment with the bayonet ' slots 30 and 31 and then pulling the cap flange 26 out of the neck flange 17 and the brush 36 out of the container. The brush may now be used to spread the liquid or to apply additional liquid, as may be desired, the spout 11 serving as a handle for the brush during this operation.

In order to reconnect the spout and brush assembly to "the container, the brush is inserted through the opening within the inner surface of the container neck flange 17, the inwardly tapered inner surface of this flange facilitating the re-entrance of the bristles of the brush into the container, the cap flange 26 is seated in the neck flange 17., the pins 32 and 33 being passed inwardly of the container through the bayonet slots 30 and 31, and the cap is then given a limited rotational movement to move the pins out of the bayonet slots through which they were passed toward the inner end of the neck flange 17 and into angularly extending portions of the bayonet slots, as illustrated in Figure 5, or to predetermined positions against the inner edge of the flange 17. When the stopper 13 is now applied to the outerend of the spout 11, the container is sealed to prevent the evaporation of the liquid in the containerand the spillingof liquid from the container, in the event the container should be accidentally upset.

The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiment is, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are, therefore, intended to be embraced therein.
