DISPENSING CONTAINER Filed Dec, 7, 1927 2 sneets sneet 2 INVENTDE extends the dispensng tube 12. `The dispensing tube is preferably straight sided for a part of its length, the lower portion being somewhat tapered.

The brush head comprises a threaded cap adapted tobe threaded on the threaded outlet of the casing and having a tubular extension 16 forming a guide and protection for-the dispensing tube 12. About the cap is positioned a band l?, the recess between the band 17 and the tubular extension 16 forming the space for the butts of the bristles 18. The under side of the brush head preferably engages the top oi the fla nge of the dispensing tube and clarnps itagainst the grooved end 'of the easing, thus preventing accidental disengagement due to pres sure of the contents'.

The bristles are preferably provided with ametal binding band 19, the eng-aging surfaces of the said band 19 and the interior of the band 17; being suitably knurled to prevent rotationof the bristles relative 'to the head.

As it is desircble that the user be able i to see the amount of soap which is eXuded from the dispensing tube, I preferably give the end of the latter a slight outward curve as indicated in Fig, 1.

, In Fig. 4 the dispensing container is shown ready for shiprnent, a cap 20 being screwed on the end of the container. A suitable cork o'other seal'will be placed in the cap to make the diseharge end of the container air tight. To protect the material at the'lowerend of the `'eontainen I preferably place over the bottom of the container a rubber cap 21. I 7

In the Construction described, the piston may be easily retraeted to perinit of refilling of the container. r If it is desired to prevent refilling, I may, as'shown in Fig. 5, stamp up from/the fianged disk 2 spring fingers 21 Which'are adapted to engage in notches formed in the r'o table disk and prevent move-` ment in the reverse direction. v

In this form the container l is also slightly flared with the larger diameter at the "bottom. Inthis case the part of the plunger will be formedof a material adapted to be compressed "and to retain said compressed shape when pressure is released. As the plunger is forced to the, top of the container 'the diameter of the plunger is thus reduced,

with the result that if an attempt is made to lower the plunger, it disengages from the wall of the container and therefore rotates V with the stern and does not move any farther downwardly A double protection against refilling is thns afi'orded. e

The tapered container also forms amore convenient handle, as the danger of slipping from the hand is', reduced. e

What I claim is: i v l A dispensing container having an open opening through 'which the stern extends; a

end; a flanged disk sleeved within said open end and forming a closure thereior; a rotatable disk at the outer side of said fianged disk; a threaded stem rotatable with said rotatable disk, said anged disk having an opening through which the stern extends; a piston threaded 'on said stern within the casing; and an inturned fiange on said container adapted to retain the rotatable disk in its position against the fianged disk.

2. A dispensing container having an open end; a fianged disk sleeved within said open end and forming a closure therefor; a rotatable diskat the outer side of said fianged disk; a, threaded stern rotatable with said rotatable disk, said fianged disk having an opening through which the stern extends; a piston threaded on said stern within the casing; and an annnlar member adapted to be sleeved within the flanged disk, having an inturned fiange adapted to retain the rotatable disk in its position against the flanged disk and an outturned fiange seemed to 'the lower end of the container.

3. A dispensing container having an open end; a fian ed disk sleeved within said open end and formin a closure therefor, the fiange of said disk having an outwardly directed portion adapted to engage the end of the container; a rotatable disk at the outer side of said anged disk; a threaded stern rotatable with saidrotatable disk said flanged 'disk having an opening through ;which the stern extends; a piston threaded on said stem within the container; and an annular member adapted to be sleeved within the fianged disk and having anjintnrned fiange adapted to vretain the rotatable disk in its position against the fianged disk and an outturned fiange adapted to overlie the outwardly directed portion of the fianged disk, said fianged disk and annular member being seemed to the lower end of the container. j i

, 4,. A dispensing container having anopen bottom; a flanged disk sleeved within said open bottom; a rotatable disk in said flanged disk; a threaded stern rotatable with said rotatable disk, said fianged disk having an With finger-engaging means; and means forming part of the container for preventing movement of said disk longitudinally of the casing in either direction.

6. A dispensing container comprising a tubular casing having an open end; a threaded stern; a piston threaded on said stern; a rotatable disk within the casing and accessible through said open end for oper` ating said stern; and means for preventing movement of said disk longitudinally of the casing in either direction, said container being tapered With its smallest diameter at its upper end, the piston being normally of a size to fit the portion of largest diameter, and having a peripheral portion formed of compressible material.

7. A dispensing container having an open end and an inturned flange at said open end; a threaded stern rotatable in said container; a rotatable disk, for actuating said stern positioned within the Container and abutting said fiange, said disk being provided With finger-engaging means; a piston threaded on said stem; and means within the container and forming part thereof adapted to retain the disk in its position against the flange.
