UNITED STATES 1 PATENT OFFICE 2,376,222 v DISPENSING cou'rnmsa .Sidney D. Barlow, Bronx, N..Y. Application ltiarchl, 1943, Serial No. 477,535

7 Claims. (01. 120-46) This invention relates to containers adapted to supply a fluid under moderate pressure such for example as supplying a continuous feed of such fluid. It is particularly intended for use with marking devices of a wide variety, but I have chosen. for illustration 9, device for permanent identification of textiles.

In a previous patent granted to me Jointly with Philip Sussman, Patent No. 2,211,312, we disclosed certain constructions for fabric marking devices comprising metal tubes adapted to contain a quantity of fluid or viscous ink and having at one end a valve controlled marking tip so constructed as to discharge an amount of ink sufficient for marking.

The ink used in this device is rather thick in consistency and it is expelled through the marking tip by pressure exerted upon the body of the ink within the device. During marking on textiles for which the device is intended, some of the ink is absorbed and thus an appreciable quantity is used. It is desirable that the device be capable of continuous use for a considerable period of time, thus the means for creating and maintaining the pressure should provide a resiliency in the pressure so that the discharge of ink does not too rapidly relieve the pressure. For these reasons, hydraulic pressure such as the direct I pressure upon the ink itself does not prove satisfactory.

It is the object of this invention to provide a device by which such a relatively continuous pres- The invention accordingly comprises an article of manufacture possessing the features, properties and the relation of elements which will be exemplified in the article hereinafter described and the scope of the application of which will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description taken in connection with the accompanying drawings, in which:

In the drawings, Fig. 1 is ,a sectional view showing a device embodying this invention.

Fig. 2 is a similar section showing an alternative construction adapted particularly for use where the lining element or sack is of thin material.

Fig. 3 is an alternative construction.

Fig. 4 shows details of the. fastening means fo the upper end of the tube in the construction of sure can be created and-maintained and yet such that the device may be made inexpensively and of simple materials.

The construction of the prior patent is highly satisfactory for its purpose, but it requires that the tube be refilled with the pigment from time to time which is a somewhat untidy operation and moreover, that construction was made of metals which have become scarce and expensive and which are not available under present war conditions. It is a further object of this invention to provide a device of the character described which will be inexpensive in construction so that it may be used once and then discarded, but which never-the-less will be wholly satisfactory during use, and which will prevent evaporation of the solvent from the pigment while in the device.

It is a further object of this invention to provide a device which may be made of inexpensive materials, which will be relatively free from war time restrictions, for example such as paper, wood,

or plastics.

' Referring now'to Fig. 1, it will be seen that the device comprises primarily an outer shell ill of cardboard or the like and an inner flexible-wall container l I within said shell which may be made of a thin flexible plastic sheet or of paper treated with any of a variety of plastics selected to make the paper water-proof and durable and suitable to receive a pigment Ila.

I have found satisfactory results from the use of Cellophane. Normally, that fabric does not possess very great resiliency, but in the form which it is used in thi device a very substantial resiliency is obtained.

-A breast plug [3 of generalconical construction is provided with an undercut annular surface l5 substantially equal to the inner diameter of the shell I0 allowing only sufllcient room between them to enable the breast member to be forced into the shell with the lower end I6 of the container to be embraced between them.

v The parts are preferably reinforced by an. adhesive to insure their sticking together.

The breast member I3 is provided with a hollow nipple as shown at iii to facilitate the adjustment of a marking tip as shown in Fig. 2.

With most pigments used, it is desirable to have the'marking tip permanently attached because if the tip be removed the ink contained therein would dry out so rapidly as to interfere with the operation of the valves. The nipple is preferably screw threaded into the tip to hold it very firmly in place. If, however, with any given pigment, it be desired, the nipple end of the device may be closed by an imperforate cap is for he partthereof. Asillustrated, it comprises priinariiyaconicaltip Ilscrewedontotheendof the breast member is having a dispensing opening8linitslowerendclosedbyaspringpressed ball valve 81 which protrudes slightly beyond the opening, so that during the dispensing operation itwillbeprcssedback intotheconicalmemberto feed the material. It will beunderstood, however, that any suitable tip may be employed.

The inner container u is preferably slightly 7 larger in diameter than the shell II and of an appreciably greater length but only its lower portion will be filled.

By reason of this fact the pressure of the contents of the container ll presses its wall firmly against th interior wall of the shell, so that there is no tendency of the 'body of the flexible container turning within the shell to twist oi! the tube at the top.

Fitted upon the other end of the shell I. is a telescoping shell 23 fitting over the shell I and rotatable upon it. The outer end 24 of the container Ii is held in the outer end-.of the shell a.

by means of a plug 2! of such diameter as to bindthe ends of the container against the in-' ner walls of the shell and the opening 26 is preferably provided in the plug ii to permit the exit of air as the inner container is twisted.

With the above construction it will be clear thatas the container II is longer than the shell, it will have a collapsed portion its up above the material contained therein, thus, as the outer shell 23 is twisted, the inner container II will commence to twist at the collapsed portion and thus the open end ofthe inner container is shut oil by the twisting. As the twisting continues during use of the device, the contents are expelled from the container and gradually the whole contents are discharged.

By reason of the fact that the container II is longer than the shell the empty portion of the container twists up into something of a knot. This is desirable because when the twisting commences'to put pressure on the tube, this tightly I leased by the discharge of contents. this tightly twisted portion untwists somewhat.

I prefer to make the tube 50% longer than the container, but the result of this invention can be accomplished by a lesser length, and to obtain the best results it should be at least 25% longer.

It will be noted that there is no tendency for the container to commence to twist at an intermediat portion where it is filled with the contents particularly because the tube itself is large enough to permit the contents to exert consider-. able friction on the inside of the shell, until the actual twisting commencing at the surplus end actually pulls the container away from the shell, and also because the original collapsed portion near the outer end furnishes a point of much less resistance to twisting than these portions of the tube that are inflated with the contents. As the inner tube twists it tends to shorten, but by reason of the fact that it is much longer than the.

ire-lasso outer container this imposes no longitudinal strain upon the inner container itself.

In the form of the construction shown in Fig. 2, there is provided an annular plug ll of a diameter to fit tightly within the shell ill and a. second annular plug ll of a diameter to turn freely within said shell. A plug 32 extends through the central opening of the plug 30, and turns freely therein, but it fits tightly within the i0 interior of the outer. end of the container H when it is placed within the opening a in the inner plug ll and within the upperend of container II. A knob 34 maybe fitted over the outer end of .the plug 32 to provide a ready means of tuming the same and thereby turning the annular plug 3!, and twisting the inner container.

The other end of the container II is fitted with gaging II, but similar to the one disclosed in In this em out of Fig.2, it is not necessary to provide the secondary shell 23.

In the form of the invention embodied in Fig. 3, the breast member H8 is fitted directly within the container II and it extends forwardly as at 25 Ill to provide a threaded nipple of a size and shape to receive the customary screw cap Illa. The inner container II has its forward end ex- I tending through opening III in the nipple end of the member III, and annular member H6 fits within the outer nd of the inner container as the latter fits within the breast opening I. The other end of the fiexibie container it extends through a central opening I il in an annular plug ill and within the outer end of the container II as it extends through said opening, there is provided a wedged shaped plug Ill arranged to force the goods into firm contact with the surface Ill. Thus plug I has an annular groove I20 adapted to receive and fit snugly against an annular plug lfl fitting with a non-rotating fit on the interior of the shell.

The details shown in Fig. 4 comprise the elements Ill, H0, iii and it will be seen from this figure the annular ring lfl may conveniently be split along its diametenso as to facilitate its ready assemblage in the manufacture of the device.

with any of the above constructions, it would be clear that the device is constructed with a small expense and it is both rigid and serviceable, and mail modifications the contents are discharged to the marking pointby twisting the end of the tube. yet at the same time the marking fiuid is sealed against evaporation.

This device has been particularly illustrated as a device for marking textiles. It will be understood that it is capable of a wide variety of uses whether it is desirable to dispense a fluid or viscous material under moderate pressure, and while it has been illustrated in connection with a ball type of dispensing tip, any type of tip may be employed wihch will properly control and distribute the material. Another important advantage lies in the fact that the operator may Having described my invention, what I claim as new and desire to secure by Letters Patent, is:-
