STMPING DEVICE Filed April 26, 1967 United States Patent O 3,444,808 STAMPING DEVICE Gilbert Schwartzman, 20 Wilmot Circle, Scarsdale, N Y. 10583 Filed Apr. 26, 1967, Ser. No. 633,889 Int. Cl. B411 27/26,l B65d 45/00 U.S. Cl. 101--125 8 Claims ABSTRACT OF THE DISCLOSURE A stamping device comprisinf a squeeze container having an applicator disposed in its neck. The applicator has a web provided with a valve opening therethrough. A valve member is disposed in the opening and engages the web for closing the opening, A retainer ring provided with a fabric cover forms part of the applicator. A duplicating stencil is disposed over said cover and a cap having an opening therethrough is secured to said container with said cover at least under slight compression so that at least a portion of said stencil sheet protrudes beyond said cap.

This invention relates to a stamping device and has for an object the provision of means for controlling flow of ink or other duplicating liuid from a squeeze container to a stencil sheet in a manner to insure optimum reproduction of the stencilled material, and in which the stencil sheet is readily replaceable.

Briefly, the concept of this invention contemplates a stamping device comprising a squeeze container having a neck portion. A body is received in the neck portion and has a web provided with a valve opening therethrough. A valve member is disposed in the opening and is engageable with the web for closing the opening. The body further includes a retainer ring having a flange. A fabric cover is secured to the retainer ring outwardly of the container. A duplicating Istencil sheet is disposed over the cover and a cap having an opening therethrough is secured to the container with the cover at least under slight compression so that at least a portion of the stencil sheet protrudes beyond the cap.

A further `object of the invention resides in the provision of a normally closed valve structure for the stamping device including resilient means on both sides of the valve seat for urging the valve closed thus insuring optimum control and safe guard against spillage.

Another object of the invention resides in the use of a valve member for an applicator which is movably mounted with respect to the valve seat yet which is locked against accidental displacement from the applicator.

Still further objects of this invention reside in the provision of a stamping device especially adapted for dating documents, for use by postal ofcials, for indicating payment or receipt of bills, invoices or like documents, which is exceedingly easy to use, inexpensive to manufacture, and which is substantially foolproof.

These, together with the various ancillary objects and features of this invention, which will become apparent as the following description proceeds, are attained by this stamping device, preferred embodiments of which are illustrated in the accompanying drawings, by way of example only, wherein:

FIG. 1 is a perspective view of a stamping device constructed in accordance with the concepts of the present invention;

FIG. 2 is an enlarged vertical sectional View taken along the plane of line 2-2 in FIG. l;

FIG. 3 is a view similar to FIG. 2 showing the stamping device in use and with the valve in an open position;

FIG. 4 is a schematic view illustrating the manner in which the valve assembly is formed;

FIG. 5 is an enlarged sectional detail view taken along the plane of line 5 5 in FIG. 2 illustrating the construction of the cover; and

FIG. 6 is a sectional detail view illustrating a modified form of the invention.

With continuing reference to the accompanying drawing, wherein like reference numerals designate similar parts throughout the various views, reference numeral 10 is used to generally designate a stamping device according to the present invention. The stamping device 10 includes three main parts; a squeeze container 12, an applicator 14, and a cap 16.

The squeeze container 12 is made from polyethylene, polyurethane or other similar synthetic plastic material and may be of any suitable shape and is provided with a neck 18 having external threads 20. The container is adapted to `be lled with a duplicating uid such as conventional stencil ink, or when the device is used with hectographing material a spirit uid such as alcohol or the like.

The applicator 14 is adapted to be mounted in the container 12 and includes a body 22 of generally cylindrical shape which projects into the neck 18. Integrally formed with the body 22 is a web 24 having a tapered opening 24a therein which opening is larger at the top than its bottom. integrally formed with the web 24 is a retaining ring which includes an outer ange 26 as well as an inner ilange 28. The outer llange 26 is swaged over a twoply fabric cover 30, the construction of which can be seen best in FIG. 5 and which includes a lower layer 32 of ink absorbent material such as felt or the like, and an upper layer 34 of a porous fabric such as woven cotton or the like. The cover- 30 is adapted to abut against a stencil sheet 36 which is held in place by the cap 16. The cap includes a downwardly projecting cylindrical portion 38 having internal threads 40, which are threadedly engaged with the threads 2i) of the bottle, and when the cap is rotated, draw the cap 16 downwardly over the applicator 14. The side walls of the cap are knurled as at 42 for facilitating the rotation thereof. The top 44 of the cap is provided with an opening 46 therein through which the stencil sheet 36 and the cover 30 is adapted to project. Disposed between the web 24 and the cover 30 is a compressible body 47 formed of a porous foamed plastic or sponge-like material. Because the body 47 is under compression, it will tend to move the cover and the stencil sheet 36 upwardly through the opening 46 and when the cap 16 is screwed down tightly, the top of the stencil sheet 36 assumes a substantially flat position whereby an impression made on the stencil sheet can be transferred to any suitable surface.

The applicator further includes a valve member 48, which has a valve head 5G which is outwardly curved and flared and so arranged that the peripheral edge 51 is adapted to engage the valve seat 24a to form a tight fluid seal. The valve head Si) is integrally formed with a plate 53 which is integrally interconnected with the ring 52 by means of three flexible resilient helical springs S4 integrally molded as a part of the valve member 48. The springs 54 are under continuous tension thus urging the valve head 50 continuously toward engagement with the valve seat 24a. The ring 52 sits in a shoulder 56 formed in the lower end of the body 22.

The valve member `48 cannot fall free of the applicator because during the manufacture of the rvalve member and its installation in place, the tubular portion 58 of the valve head 50 as defined by a central opening 60 is ared outwardly by use of a tool V62 provided with a conical head 64. The tool is preferably heated and when applied causes the valve head to achieve the tiared shape as shown in FIG. 2.

In use, a stencil disc or sheet has typed thereon any suitable indicia such as the date shown on the stencil sheet 36 in FIG. 1. Then, the stencil sheet is inserted into the cap and the cap screwed down after which merely squeezing the containtr 12 as shown by the arrows in FIG. 3 will cause pressure on the plate 53 and the valve head 50 to open the Valve head and permit iiuid flow in the direction of the arrows in FIG. 3. A suitable amount of ink or duplicating uid will be metered to the stencil sheet 36 and the date or other indicia on the stencil 36 will be transferred to the document or other suitable surface as desired.

In FIG. 6 there is shown a modified form of the invention in which the neck 66 of a container is provided with an outwardly turned lip 68 so that the cover 70 which has a downwardly and inwardly extending ange 72 may be `snap-fitted in place in lieu of being threadedly secured. This for-m of the invention functions otherwise in the same manner as the embodiment shown in FIGS. 1 through 5.

A latitude of modification, change and substitution is intended in the foregoing disclosure, and in some instances some features of the invention will be employed without a corresponding use of other features. Accordingly, it is appropriate that the appended claims be construed broadly and in a manner consistent with the spirit and scope of the invention herein.
