ll tale ROBERT H. VAN SANT OF CETCAGO, ILLINOIS, ASSTGNQR, BY MESNE ASSIGNMENTS,

TO GOLD DUST CORPQRATION, OF NEW YORK, N. Y., A CORPORATION OF NEW JER- GLASS-CLEANING APPLICATOR.

Application filed January 22', 1925.

This invention relates to a glass cleaning applicator adapted to form the closure for a can or container or the like, containing cleansing fluid.

It is an object of this invention to provide a container closure adapted for cleaning glass such as window panes and the like, and which is so constructed that the rubbing action upon the glass will not obstruct or impede the flow of cleansing material from the container, and that will thoroughly and effectively cleanse the glass, and will sealcleanser involving this invention.

Figure 2 is a. side elevational view of such container.

Figure 3 is a top plan view of the cleaning applicator or device.

Figure 4 is a fragmentary enlarged sectional View through the container and cleansing applicator with the container sealing disk in position.

Figure 5 is a view similar to Figure 4: with the sealing disk removed.

Figure 6 is an enlarged sectional view through the cleaning applicator upon the line VIVI of Figure 8.

Figure 7 is a top plan view of a modified form of applicator.

Figure 8 is a section upon the line VIII- VIII of Figure 7 Referring to the drawings it will be observed that there has been illustrated a container 1 adapted for containing a glass cleaning or cleansing fluid. The upper terminal of the body portion of this container which preferably consists of sheet metal or the like is provided with an outwardly returned bent margin 2. A top portion provided with a sloping or inclined nozzle 8 has a lower inwardly returned bent margin 4 engaging under the upper returned bent margin 2 of the container. The nozzle 3 of this top por- Serial No. 4,127.

tion is externally threaded for a he cleansing applicator 5 comprises substantially aconvex flexible member made of rubber or the like and provided upon its margin with an attaching flange 6 which is seated upon an inwardly directed annular flange 7 at the mouth of the nozzle. A cylindrical sleeve 8 which is threaded for engaging the threaded nozzle has an inwardly directed annular flan e 9 which engages over the top of the flange 6 for clamping the applicator in position on the container.

The convex surface of the cleansing applicator is provided with projecting or raised portions which may be in the form of crossed ribs 10 as shown in Figure 3 or may be in the form or" a central elevated portion as shown in Figures 7 and 8. In the angles of the cross and adjacent the raised central portion are apertures or ports 11 through which the cleaning fluid from the container is adapted to escape. It will be evident that these raised portions adjacent the apertures 11 will prevent the same from being closed during the cleansing operation, Obviously without such raised portions the apertures 11 would be partially closed during the cleansing operation so that the flow of the cleansing fluid would be greatly restricted or impeded.

The containers filled with cleansing fiuid and equipped with an applicator form an article of commerce and to prevent the fluid from escaping, a sealing disk 12 (Figure 4c) is placed upon the top of the container. This sealing disk in the present instance has a central depression that fits within the opening defined by the flange 7 and a felt washer 13 or the like superposed thereover;

the sealing disk being compressed between the applicator and the top of the container.-

Of course in the use of the device the sealing disk is removed as shown in Figure 6.

In the use of this device the container is grasped in the hand and tilted to allow the fluid to flow therefrom upon the glass that is to be cleansed, at the same time the applicator is rubbed over the glass as is apparent, undue pressure upon the applicator will cause the raised portions to flatten and prevent or restrict the flow of ointment. Thus the raised portions serve to regulate the pressure that should be applied to the applicator, and informs the operator when undue or excessive pressure is applied reducing thereby the tendency to break the glass. Further on account of the slope of the nozzle, it is possible to maintain a flow oi ointment through the applicator through a lesser degree of tilting or inclination of the container.

1 am aware that changes may be made, and details of construction may be varied without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted thereon, otherwise than necessitated by the scope of the claim.

.l: claim as my invention:

It flexible applicator consistiin of a hollow lire rubber body ojt' substantially hernispherical torni having means for attaching the same to a container with its convex face outermost and With its said body projecting in its entirety beyond the container for free flexible movements in all directions When applied in use, said body having apertures therethrough adjacent to its center and having a thickened wall portion adjacent to said apertures forming an external projection upon its convex taco extending beyond the outer ends of said apertures, said apertures extending through the relatively thinner portions of the ail of the body, whereby they will remain open in use as long as the applicator is applied with a force insufficient to flex the said projection inwardly to and beyond the external surface of the body.

In testimony whereof I have hereunto subscribed my name.

ROBERT H. VAN SANT.
