Projecting from the-shoulder portion l6 of the tube I4 is a neck l8 adapted to project outwardly from the casing l0, when the shoulder I6 is in abutment with the shoulder" of the casing in. The neck l8 has a passage l3 therethrough which is in communicationwith the interior of the tube l4. The external surface of the neck I8 has thereon screw threads 20. The screw threads 20 are adapted toreceive a cap 2| which has a conical shaped head, 22 with a c amber 3 therein.

An orifice 24 is in the apex of the conical head 22 of said cap. A ball 25, which serves asa marking ball, is positioned in the orifice 24 Apin 26, having a head 21, is acted upon by a spring 26, said spring acting to retain the ball in a seated position, the same being positioned between the bottom surface of the head 21 and a washer 29' when the casing is compressed and through which neck l8 and screwed downwardly onto said-neck V air may be admitted when the pressure is released from the casing It. i

As shown in Figure 4 ofthe drawing, the casing It has a taper 3| at the bottom thereof, which taper has at the end thereof adjacent extensions 32 and 33 adapted to be spread apart and admit the container tube H, which extensions may thereafter be sealed by rubber cement, or any other means, as hereinbefore set forth.

In assembling the marking tube of the present invention, it is merely necessary to insert the container tube i4 between the projections 32 and 33, sliding said container tube inwardly until the neck I 8 passes through the opening I 3 in the opposite end of the casing ill, and the bevelled shoulder I6 of the. tube l4 abuts against the bevelled shoulder l1 onthe interior of the casing Ill.

The washer 29 if one is used, is placed upon the top surface of the screw-threaded neck l8. and the spring positioned on topof the washer. The pin 26 is then inserted through the spring, the washer, and into thepassage IS. The ball 25 is positioned in the orifice 24, after which the cap 2|, which is screw-threaded internally, is positioned uponthe external threads 20 on the until the bottom surface 34 of the cap 2| engages the top surface, 35 of the casing l0. Further screwing downwardly of the cap will draw the shoulder 6 of the container tube |4 tightly against the shoulder I! of the casing i0. and thereby firmly hold the container tube within the casing.

When it-is desired to write, the casing I0 is compressed by'the operator, which will, in turn, compress the tube l4. The pressure causes the viscous marking fluid to fiow through the pas.- sage is into the chamber 23. The-operator may then release pressure from the casing Ill, which casing immediately returns to its original, or normal, shape, air being admitted through the vents 30. The container tube |4, however, since it is of a non-elastic material, retains itscompressed condition within thecasing' it, so that air cannot be drawn back into, the container K container tube 4.

ing the marking fluid to flow through the oriwhen the container tube H has become empty, if it is desired to remove the same from the casingthis may easily and quickly .be 'done by unscrewing the cap 2| from the neck l8 of the projections are'pried apart or if held together by a-clip the clip is removed allowing the pro- Jections to be spread apart. The container tube I4 is then withdrawn from the casing Hi. There are no partsto be removed from a discarded tube. nor are there any parts to be placed within .the container tube i4 before it is inserted in the casing. It is merely necessary to screw'the cap 2| onto the neck of the container tube-over which has been placed the spring 23 and ball 25 which rests upon the pin 26, projecting through the spring and into the passage Hi. When the cap is removed the ball 25, pin 26 and spring 28 as wellas the washer 23 will fall free of the empty container tube. v

It is apparent that the specific illustration shown has been given by way of illustration and not by way of limitation, and that the structure above described is subject to a wide'variation and modification without departing from the scope or intent of the invention, ally of which variations and modifications are to be included within the scope of the present invention.

What is claimed is:

1. A marking implement having a collapsible elastic tubular casing, a tubular container of substantially non-elastic material for containing a marking substance positioned within said casing and having an externally threaded neck projecting outwardly through an opening in one end of the said casing, a discharge member threaded internally at one end thereof andadapted to be positioned onsaid threaded neck and drawn tightly against the casing'to hold the tubular container firmly within said casing, a combined If cemented together, the

marker and closure for the discharge member movably mounted therein a and retracable in writing position, and means for yieldingly holding the marker and closure in a projected closed position so that upon the application of pressure to said casing the shape of both the casing and container is deformed forcefully emitting said marking substance from said container pastthe retracted marker when the implement is in writing position, said casing upon release of the pressure returning to its normal condition said container retaining its compressed condition. a

2. A marking implement having a collapsible elastic tubular casing having an open end adapted to be closed and an opening through the opposite end, a tubular container of substantially 'nonelastic material for containing a marking substance positioned within said casing and-having an externally threaded neck said tube being adapted to be inserted in the open end of said casing. said neck" projecting outwardly oi" said casing through the openingin the opposite end thereof, a discharge member threaded internally at one end thereof and adapted to be positioned on the said threaded neck and drawn tightly against the casing to hold the tubular container firmly within said casing, a combined marker and 75 closure for the discharge member movably mounted therein and retracable in writing position and means for yieldingly holding the marker and closure in a projected closed position so that upon the application of pressure to said casing the shape of both the casing and container is deformed forcefully emitting said marking substance from said container past the retracted markenwhen the implement is in writing position said casing ing in tubular shape said casing having one end jecting outwardly through the passage in the neck upon release of the pressure returning to its normal condition said container retaining its compressed condition.

3. A marking implement having a collapsible rubber tubular casing comprising walls with air 15 vents therein said walls being of such thickness as to normally retain the body of said casthereof open and adapted to be sealedclosed and a neck on the opposite end thereof with a passage therethrough, a tubular container of slightly less diameter than the inside diameter of said casing said container being of substantially non-elastic material for containing a marking a substance adapted to be positioned within said casing through 'the'open end thereof said -'container having an externally threaded neck proof said casing, a discharge member threaded internally at one end thereof and adapted to be positioned on thesaid threaded neck and drawn tightly'against thetop surface of the neck on said casing to hold the tubular container firmly within said casing a combined marker and closure for the discharge member movably mounted therein and retracable in writing position andmeansl for yieldingly holding the marker and closure in a projected closed position so that upon the application of pressure to said casing" the shape of both the casing and container is deformed forcefully v 3 ing of sufllcient thickness as to normally retain the body in tubular shape, a tubular container of substantially non-elastic material for containing a marking substance positioned within'said casing and having an externally threaded neck pro- 5 jectlng outwardly through an openingain one of the said casing, and a discharge member threaded internally atone end thereof and-adapted to be positioned on said threaded neck and drawn tightly against the casing to hold the tubular container-"firmly within said casing. 5.;A marking implement having a collapsible rubber tubular casing having an open end adapted to beclosed and an opening through the opposite end, the walls of said casing being of suflicient thickness as to normally retain the body in tubular.
