United States Patent 3,000,355 MARKING DEVICES Sidney N. Rosenthal, Belle Harbor, N.Y., assignor t0 Speedry Chemical Products, Inc., Richmond Hill, N.Y. Filed Aug. 24, 1959, Ser. No. 835,459 1 Claim. (Cl. 12042.4)

The present invention relates to marking devices capable of employing opaque inks which are in general more viscous than translucent or dye type inks.

An object of said invention has been to provide a relatively low cost marker which can be used with advantage for marking or writing on practically any soiled surfaces with a relatively viscous type of ink, or for marking textiles with a more freely flowing but somewhat viscous type of ink.

Another object of the invention is to so construct the marker that the ink, when of high viscosity, may be forced from the container in which it is carried to the writing nib.

For such purposes, a further object of the invention has been to provide a marking device in a simple compact form which affords adequate scaling to prevent loss and impairment by evaporation of the pigment carrying medium, and which is readly taken apart for cleaning and refilling or for changing from one color or type of ink to another color or type.

One embodiment of a marking device according to the present invention is illustrated in the drawings appended to this application and wherein:

FIGURE 1 is a central longitudinal section on enlarged scale;

FIGURE 2, an exploded sectional view showing construction of the parts forming the cap assembly in FIG- URE 1; and

FIGURE 3, a fragmentary view in vertical section on enlarged scale illustrating construction of the joint between the cap and the ink carrier and between the cap and the applicator or spout.

Referring to the drawings, the device there shown includes an ink container 10, conveniently in a form wherein lateral wall portions are flexible and permit the contents to be ejected by manual pressure thereon, such for example as a squeeze-bottle of polyethylene or other suitable material. Said container has an open neck 11 which is externally threaded to receive a cover or cap 12.

Cap 12 has a central opening defined by an annular lip 13 which closely engages and holds a spout and nib assembly 14. As appears more clearly from FIGURES 2 and 3, a depending annular ridge 15 coaxial with and spaced from said central opening extends from the generally flat under-surface of the end wall of cap 12, its inner surface 16 being arranged to form with lip 13 an annular recess.

The spout has a shoulder 17 at its inner end which nests in said recess; and flange 18 of the spout bears closely against the face of ridge 15. Said spout has a rounded outer end of relatively reduced cross-sectional area provided with a discharge opening 19 which is maintained normally in closed condition by a spring pressed valve ball 22 which is preferably of polished corrosion resistant material, as stainless steel. A compression spring 20 is operatively interposed between said ball 22 and a retainer ring 21.

Patented Sept. 19, 1961 Where the end wall of cap 12 is of polyethylene, or equivalent material, the thickness thereof will be such that lip 13 is sufliciently flexible to closely hug a portion of spout 14. The base portion 23 of the spout is slightly tapered and of such dimensions that when the outer end portion of the spout is pressed outwardly through the opening in cap 12 into operative position, as seen in FIG- URE 3, said lip 13 presses closely in sealing engagement around a portion of said base adjacent to said shoulder 17. Thus, the cap and spout form a leak resistant assembly which is releasably secured to the neck 11 of container 10. When the parts are all assembled in operative relation, the rim of neck 11 engages flange 18 of the spout and presses the same closely against ridge 15 thus providing a seal against leakage between the cap and the container and between the container and the spout.

In use, the marker is held in a position to feed ink into the spout; and said ink is discharged therefrom as desired by pressing the valve ball against the surface to be marked while drawing the ball and tip or spout end across said surface.

It will be realized that when ink of high viscosity is used and the marker is inverted for marking purposes, that the ink will flow more or less slowly to the marking nib. However, the construction of the container in which the ink supply is stored of a squeeze bottle form, as for instance of polyethylene, enables the user to force the ink to the writing nib by the application of pressure. Thus, the marker is in condition for successful marking immediately upon its being inverted into a marking position.

What I claim is:

In a marking device, the combination of a marking fluid squeeze type container having an externally threaded open end neck; a spout having an upper end opening and also having its lower end flaring outwardly and termination in a peripheral outward flange; with such flange seating on and engaging the upper edge of the neck; a retaining ring in said spout at its lower end; a valving ball in said spout opening at its upper end; a coiled compression spring in the spout between and bearing against the retaining ring and the ball; and an internally threaded cap threaded on said neck and having a flexible peripheral inward flange formed with a central hole whose edge is flexible and is in tight sealing engagement with the side wall of the spout at its outwardly flaring lower end; the cap flange having on its lower surface an annular rib formed and directed toward the flange of the spout and the upper edge of the neck to bear against the spout flange and press the latter tightly against the neck edge, such rib being coaxial with the neck edge.
