Jufly 116, 1935. G. R. BEEG DISPENSING DEVICE Filed Dec. 5, 1935 '[N VENTOR Z5 W TTOR NE 1 Patented July 16, 1935 UNITED STATES ,PATENT OFFICE 4 Claims.

This invention relates to dispensing devices, and more particularly to devices applicable to bottles of mucilage and the like.

Among the principal objects which the present invention has in view are: To provide an improved dispensing device which automatically seals the bottle or the like on which it is attached, and yet provides for adequate flow of mucilage or the like when desired; to prevent clogging by hardening of the mucilage after use; to enable the device to be wiped on the surface in either of two opposite directions and give a flow of mucilage under either condition; to avoid tendency to seal against discharge of the mucilage or the like during the wiping operation; to afford increased flow of mucilage or the like by increased pressure; to enable use of a wide tip to be employed for securing an even spreading of the mucilage or the like; and to obtain other advantages and results Drawing Figure l is a side elevation of a bottle having my invention thereon;

Figures 2 and 3 are sectional views shown as taken on line 22 of Figure 1;

Figure 4 is a plan View; and

Figure 5 is a sectional view of a modified construction of cap having a threaded interior.

Description As seen in the drawing, the reference numeral I0 is a bottle or the like, the upper end of which is mounted a cap II as shown in Figures 1 to 3 designed to be sold as a unitary part with the bottle, tightly fitting upon the neck 12 thereof. It is to be understood, however, that if so desired the cap may be made removable for refilling the bottle, or may be made and sold independent of the bottle, in which event it may be threaded as at l3 as shown in Figure 5, or otherwise constructed to be attached to bottles now appearing on the market.

Cap Il may be of any desired material, the construction shown being one capable of utilizing such materials as hard rubber, bakelite, and other substances which are not flexible, or if preferred, the cap may be constructed of flexible or semi-flexible material thereby enabling it to be attached to bottle necks of somewhat varying size and shape. As here shown, cap I l is frustoconical with the base portion thereof cylindrical and annular by virtue of an apron or flange portion l4, this flange portion [4 constituting the neck-engaging part of the cap ll.

Projecting from the outer or smaller end of the cap I! is a flexible and normally closed neck l5 which is preferably a construction closely resembling a spiral spring, the convolutions of which tightly close one against the other except 5 when spread apart in use as shown in Figure 3. The convolutions of this neck are resilient in order to maintain the normally closed condition above specified and to return said neck to such closed condition after release of any deforming pressure which has separated any of the convolutions. By use of a spiral spring-like neck l5, the end convolutions thereof may readily be embedded within the outer end of cap ll, seating therein as a screw in a threaded socket.

The outer end of the neck l5 carries a spreader l6 of hard rubber or other suitable material, the neck preferably having its end convolutions embedded therein, with the spreader effectually closing the outer end of the interior channel formed by the neck l5. Consequently, the only opportunity for the escape of the contents ll of the bottle ID, for convenience referred to herein as mucilage, is through the gaps or crevices between adjacent convolutions created by deformation or lateral displacement of the neck. Furthermore, the spreader may conveniently be provided with a crosshead l8 transverse to the axis of the neck and of such length, shape, and dimensions and material as found most desirable for spreading the mucilage escaping through the neck. It is preferable to have the crosshead of greater length than the diameter of the neck so as to fully spread all material discharged from the neck.

In use, it will be noted that the normal resiliency and closed condition of the spirally formed neck. l5 causes the same to maintain a tight closure for the bottle Ill even with the bottle upside down. When, as in Figure 3, the spreader I6 is pressed against a surface l9, neck I5 is deformed with gaps appearing between convolutions at the side of the neck towards the surface, therefore, contents H from the bottle I 0 will drip on to the surface. Drawing the bottle along the surface results in crosshead I8 of spreader I6 wiping over the discharged contents. Bymoving the bottle in a reversed direction, the neck swings and opens at its opposite side, and again the spreader wipes over the contents after discharge. Releasing the pressure immediately closes the neck and no further contents will be discharged.

The natural tendency to press down with greater force when insufficient contents are discharged will be eifective in the use of my invention because the additional pressure applied ob- V rupts any adhesion of the dried muciiage between convolutions of the neck and thus free passage of the mucilage is obtained just as readily on subsequent utilization of the device as exists the first time it is used.

I claim:

1. A dispensing device comprising in combination with a cap and a spreader, a flexible neck outside said device having a plurality of parts normally closed together and adapted to be spread apart by flexing said neck and thereby providing lateral openings exterior of and between the cap and spreader for enabling contents within the neck-to be discharged'adjacent the exterioroi jthe spreader. r

a 2'. A dispensing device coinpris' 1g in combination with a cap and a spreader, a flexible neck outside said device having a plurality of spiral convolutions' normally closed together and adapted to be spread apart by flexing said neck and thereby providing lateral openings exterior of and between the cap and spreader for enabling contents within the neck to be discharged between said convolutions adjacent the exterior of the spreader.

3. A dispensing device comprising in combination with a cap and a spreader, a flexible neck outside said device and embedded at its opposite ends in said cap and spreader respectively, said neck having a plurality of spiral convolutions normally closed together and adapted to be spread apart by fl xing said neck and thereby providing lateral openings exterior of and between'the cap and spreader for enabling contents within the neck to be discharged between said convolutions adjacent the exterior of the spreader. V

4. A dispensing device for applying a fluid to work comprising in combination with a bottle having a neck, a cap and a spreader, said cap fitting snugly on theneck of said bottle, a spiral spring having a plurality of convolutions normally tightly closed, one end of saidspring adapted to fit within the said cap on the inside of the neck of the bottle for admitting the bottle contents to the'exterior of the spring upon inverting the bottle, and the outside end of the spring being adaptedto support said spreader whereby on inversion of the bottle downward pressureon the spreader causes the convolutions of the spiral spring to separate and the contents from Within the bottle to escape directly therethrough onto the work inproximity to the spreader. j
