' Application April 22, 1953, Serial No. 350,459

1 Claim. (21. 15-434 This application relates to marking devices and more particularly aims to provide a marking device which is primarily a shipping container of conventional glass hottle form, but which may be equipped with an inexpensive nib construction enabling it to be used as a marking device.

A feature of the present device is that the nib construction is so formed as to provide a completely satisfactory seal for the open shipping container or bottle whereby the device is instantly useful at any time despite long periods of non-use.

Still another feature of the present construction is the forming of all parts of the device, except the bottle and its packing, in a unitary cap and nib assembly which can be transferred from an empty bottle to a fresh bottle so as to transform a new bottle of ink, not equipped with a nib, into a marking device.

A more complete understanding of the device will be obtained upon reference to the following specification in which Fig. l is an elevation view of the device partly cut away; Fig. 2 is a transverse section as if on line 2-2 I of Fig. 1.

Referring to the drawing, it will be observed that it shows, a greatly enlarged scale, a marking device which is really a combined ink bottle and pen. The bottle itself is an elongated open top glass ink bottle whose ratio of length to diameter is very large, approximately three to one, whereby the bottle can conveniently fit in the hand of the user to form the handle of a marking device. The bottle is formed with a screw threaded neck 11 and contains a packing 12 known in the trade as a felt pack but as often as not made of packing material other than felt, such as a block of sponge rubber, twisted into the bottle and providing air flow around it.

Ordinarily such a bottle is sealed and any suitable seal or cover or cap for such bottle may be utilized. One well-known cover or cap for such bottle is a sealing disc which is adhesively secured to the upper edge of the bottle and which is readily puncturable to open the cover or seal and thus enable the bottle to be used with the unitary cover assembly now about to be described.

Such assembly is a combined cap and nib unit and comprises a flat annularly flanged thin sheet metal cap 20 whose flange 21 is formed with threads to enable the cap to be threaded onto the threaded neck 11 of the bottle. Loosely fitted into a center hole 22 of the cap is a very thin sheet metal nib holder 23 of ferrule form and of considerably less diameter than the cap. Within such holder is a nib 24 commonly known as a felt nib but which may be of any suitable material, felt at the present time being preferred. The nib 24 is firmly seated in the holder and projects above and below it as indicated. The nib is of flat bar form and is pressed into the holder which is of circular form so that the holder tightly grips and holds the nib firmly in place and at the same time provides air passages 25 in the holder alongside the nib. A slip cover 26 of any suitable material such as plastic is detachably secured by friction Lil to the holder 23 to cover the nib and prevent evaporation of the ink through such nib and also to seal hole 22 for holder 23 by engaging cap 20 as shown.

The pack 12 in the bottle is in constant nib-wetting contact with the lower end of the nib projecting below the nib holder.

The nib holder has a rear portion in the form of a flared lip 28. Within the cap 20 is a gasket 29 positioned against such lip. The edge of the bottle neck, when the cap 20 is screwed down tight onto the bottle neck, is firmly in contact with the gasket whereby the bottle is sealed by the gasket. In addition, the bottle presses the gasket firmly against the lip of the holder and thus firmly presses the holder against the cap with the net result that the nib, which is firmly secured in the holder, is thereby firmly held with respect to the bottle. Thus the nib will not move with respect to the bottle when the latter is used as a handle during the Writing operation.

The gasket is of semi-hard but compressible material, preferably of a plastic material. The material is carefully selected to enable the gasket to function as a seal for the bottle when the cap 20 is threaded down tight and also to enable the gasket to transmit thrust from the bottle to the lip of the holder and thus clamp the holder firmly in the cap. Any person skilled in the art, with this information, can select the particualr gasket material to be used.

I will be observed that the device herein shown is a satisfactory marking device, but is also satisfactory commercially in that it comprises an inexpensive shipping container and an extremely inexpensive nib construction applicable to a bottle while at the same time preserving the desirable chracteristic of the pen being instantly useful for marking despite long periods of non-use, and without excessive evaporation from the bottle through the felt pack and the nib provided the cap 29 be firmly in place and the slip cover 26 likewise be normally in place.

The sub-assembly comprising the cap 20 and the parts secured thereto including the gasket 29 may be removed from an emptied bottle to a fresh bottle. The latter may have a seal to be punctured or may have a cap to be removed but in either case, once the new bottle is prepared for the reception of the combined cap and nib unit, such cap and nib unit may be removed from an old bottle and applied to the new one to convert an ordinary shipping container into a marking device.

It is of great importance that the gasket be provided for the various functions described herein, namely, to seal the bottle, and to enable the bottle to clamp the nib firmly in place with respect to the bottle.

This application is a continuation in part of my prior abandoned application Serial No. 219,018 filed April Now having described the device herein disclosed, reference should be had to the claim that follows.
