DISPENSING DEVICE.

My invention relates to dispensing devices and is particularly useful in devices that are employed for dispensing semi-fluid s oap thoughV the invention is notto he llmited to' any particular'use.

In carrying out my invention,4 a shell 1s em loyed which is preferably open at both en s and in which the soft soap or other -matter to be dispensed, is disposed. The rear end of a dispensing nozzle is initlally received in the front end of the shell and is movable from the front end of the shell toward the rear Awhereby the matter to be dispensed is forcedv through the nozzle, the rear end of the shell being then closed.v In' vthe preferred embodiment of the invention,

the shell is interior-ly threaded and the rear yend of the nozzle is exteriorly threaded, the threads upon the shell and nozzle being in mesh so that when one of `these elements, preferably the nozzle, is turned in a direction to move the rear end of the nozzle toward the rear endof the shell, the matter to be dispensed is forced through the nozzle.

My invention is particularly adapted fnr the dispensing of semi-fluid soap which 1s sold in containers and when the invention is thus adapted, the rear end of the aforesaid shell is forced against the bottom or end wall of the container, thereby closing the rear end of the shell. As the shell has snug sliding fit with and with-in the contailler, the material in th'e container is forced y into the bore of the shell as the shell is moved rearwardly preparatory to being forced into thenozzle when' the rear end of the nozzle is moved toward the rear end of" cup-like mounting that is employed to hold a wall or other supthe entire device upon port.

The invention will be more fully `er.-

' plained in connection with ,the accompanylng drawin in which Fig. 1 is a side view of the re -erred embodiment of the in vention; Fig. 2 is a longitudinal sectional vlew;

Application filed october 13, 1926. serial 110.142,130.

and Fig. 3 .is a view of the' device with the parts thereof 1n separated relation, all of the parts beingA shown 1n longitudinal section with the exceptionof the container` which is shown partially in section and partially in elevation.

The dispenser illustrated includes an interiorly threaded hollow cylindrical shell l which is open` at'both ends. The nozzle Qis of funnel formation and is provided with threads 3 at its rear end, these threads meshing with the threads upon the interior of the shell. The front end of the nozzle bore is formedto impart the desired shape to the stream of soap or other matter that is being eXuded. The nozzle is exteriorly threaded at'its frontend to receive a nut l which serves to clampv a gripping wheel 5 against the shoulder 6 upon the nozzle.-

This gripping wheel is desirably knurled and is of such diameter that it may readily be grasped to turn the 'nozzle within the shell. The shell is adapted to have snug vsliding tit with and within the cylindrical wall of the container 7 which holds the soap 7 or other matter Vthat is to be dispensed.

In the use ofthe device, the cover of the container is removed and the shell is forced into the container' and as the shell has sliding fit with-and within the container. the material in the container is practically .entirely forced into the bore of theshell', no

appreciable amount of this material escap` ing between the shell and the container.

After the shell has been inserted fully withinthe container so that the rear end of thel shell engages the bottom ot' the container,

and assuming that the rear end ot' the nozzle hasbeen screwed into the position illustrated in F-ig. 2, the clamping sleeve '8 is .applied This clamping sleeve has an annular shoulder `9 at its forward end which engages the forward end of the shell l. The rear end of the clamping sleeve 8 is exteriorly threaded and is screwed into the threads providedupon the cylindrical wall of the mounting cup 10. The clamping sleeve 8, whichl surrounds the shell ll. and

the container 7, -when being screwed `into the mounting cup, holds the inner end of the shell against the bottom wall of the container. If the shell has not been initially placed in actual engagement with the Abottom of the container, the adjustment of the clamping sleeve will complete the movement of the shell against this container bottom. As illustrated, the mounting cup l is secured bymeans of screws lll upon a-wall12.

The shell l is' desirably of such length that when the device has been supplied with a fresh container of the material that is to be dispensed, it will project'beyond the conlainer to an extent equal to the axial length of the rear threaded portion of t-he nozzle that is surrounded by the shell and clamping sleeve.`

When the rear end of the nozzle has been rearwardly moved longitudinally 'of the shell sufficiently to bring this nozzle end against the bottom of the container, no further material can be -dispensed from the device until a fresh. container has been sub.

stituted. When the rear endof the nozzle has reached its rearmost position, a residue remains 1n the nozzle as indicated 1n Fig. 3.

this residue being the first to be'ejected when the device is used after the substitution ot front end of the shell, Fig. 3,"to have its assembly with the shell v renewed lat this point, the nozzle being screwed into the shell to the position indicated in Fig. 2 before the clamping sleeve 8 is applied.o The' -shoulder on the clamping sleeve is desirably of such size ,as to slightly lap the threaded rear portion of' the nozzle yon which account said sleeve is passed over the discharge end of the nozzle in being brought to. position, the l gripping Wheel-being of sufiiciently smallA diameter to permit it to pass through the opening 9" surrounded by said shoulder.

as will be readily understood.

lVhile threaded engagement is preferably employed between certain parts of thedevice, as illustrated, it is obvious that the invention is not to be thus limited in all embodiments thereof.

The parts may be assembled in other ways,

`my name.

Changes may be made without departing fromthe invention.

Having thus described my invention, I

' shell and spaced apart therefrom to permit a 'wall ot a container to be received between the shell and sleeve and formed, at its forward end, to engage a forward end portion of the shell and' exteriorly threaded at its .rear end; and an interiorly threaded cup whose threads mesh with the threads upon the clamping sleeve.

2. A dispenser including an interiorly threaded hollow cylindrical shell, open at both ends; a nozzle exteriorly threaded at its rear end, the threads upon said shell and nozzle meshing, the threads upon the shell being continued to enable the rear end of the nozzle to be moved toward the rear end .of the shell; and means for clamping the shell against the bottom of a container into which the shell is adapted to be inserted. i

3. A dispenser including a. hollow .cylin-v.

drical shell open at both ends; a nozzle having a. re'ar end in snug fit with' the shell and` movable from the front to the rear of the shell;- a clamping sleeve surrounding the shell and spacedapart therefrom to permit a wall ot' a container to vbe received between the shell and'sleeve and formed, at its forward end, to engage a'forward end portion of the shell and threaded at its rear end; and a threaded cup whose threads mesh with the threads upon the clamping sleeve.

4. A dispenser including ahollow cylindrical shell open at both ends; a nozzle having a rear end in snug fit with the shell and movable from the front to the rear of the shell; and means for clamping the shell against the bottom of a container .into which.

the shell is adapted to be inserted.v
