'Application filed February This invention relates to a combined container and grease gun, and has for its object the. production of a simple and efiici-ent container and dispensing mechanism whereby semi-fluid materials such as pastes, creams, gums, greases,v ointinents, powders, and the like are stored and dispensed c s and when required.

Another object includes the production of construction which will fully protect the material but which adordsready ineansfor dispensing said material with ease, and certain in controlled quantities.

Aiuther objec includes the provision of a simple and eiiicient dispensing container which protects the materials against loss and deterioration through exposure, oxidation and evaporation. I further provide a container or the type specified, which is provi ed with effective control parts in the form of a movable bottom portion, which cooperates with an adjustable discharging device and means varying the relative distances of-said parts from the discharging end or the container, and from each other.

Other objects will appear hereinafter, and I attain these objects by the construction illustrated by the. accompanying drawing, in which Fig. 1 is a. plan view of a construction which embodies the principles of my invention.

Fig. 2 is a plan view of a slightly different form of construction from. that disclosed in Fig. 1.

. Fig. 3. is a section taken on the l-ine-33of Fig. 1.

4 is a section taken on the line l d of Fig. 2.

Fig. '5 is a view in section of a modified form of adjustable discharge device or plunger with its control stem.

' Like numerals refer to similar parts throughout the several viewswhereverthey occur.

It is among the prime purposes of my invention to produce a simple and inexpensive dispensing container which comprises a main body part, of cylindrical or other shape, closed at one end, and provided with a movable cap and control device at the other. lhe dispensing container, in its simplest form, comprises a body 10, which is open at (the lower} end 11, at its other end KILLARA, SYD' TE EllilGLzllJidD, All JOHN RAIN; 01'4" OTTAWA,

terial; In 4, the opening is located centrally, and in either case, the screw cap 14 fully protects the contents of thecontainer. The open, or operative end 11 of the main body part is provided with a control cap or thinible 16, or 16, which .slidahly tits on the main body part.

in F 3, this cap fits over the end" ot-the 601111 211615 body, while in the construction of Fig. 4, said cap 16" fits within, the container; In either case this cap is reciprocably held, andis provided with means for dispensing the contents This dispensing means, in a preferred con struction, consists of an adjustable piston or plunger 17 (or 17) having a sealing member 18 (or 18; to form a slidable non' leak connection with the inner wallsof the container. This piston or plunger will be shown herein as the adjustable dispensing member, and has centrally placed screw threaded bore through which operates the adjusting stem or member 20 (or 20 for compressing the material within the container to thus cause the desired amount to be extruded from the nozzle after the cap, 14', has been removed. The compression or moving force is effected by merely pressing the cap and the container body togetherthe eces-sary distance, thereby causing the dispensing member'or plunger to be, moved upwardly, that is, towards the dispensing nozzle. Vfhen the thirnble has been. moved torward, to say the end of its movable distance, or a portion thereof, it is readjusted, or caused to be withdrawn for future use. This readjustment is efiected by rotating the screw-stem so as to readjust the thimble', that is, cause it to be again moved away from the end 11 for future use. If the adjusting stem is secured to the bottom of the thimble, as in Figs. 8 and i, for example, then will the readjustment be made by merely turning the cap to unscrew the stem.

of the container.

. place.

It, on the other hand, the container and thimble are of other shape than cylindrical, as for example, polygonal, or oval, or other form, then-will the stem have to be rotated independently of the cap for readjustment. This may be effected in numerous ways, as by keeping the foot 22 of the stern unsecured at the bottom of the thimble, so that the stem can be unscrewed. tion, to keep the cap or thimble from falling off, I provide a frictional connection between the body and thimble, and the thimble or cap trictionally engages the side walls of the body member, either externally, or internally. For some purposes, I provide the connecting joint ends of the body and the thimble, respectively, with stop rings 31 and 31. l he stem may be cut screw-threaded, as is shown in Figs. 3 and 5, for example, or it may be a simple coiled corkscrew type of stem. If desired, a stop nut 32 may be provided. The sealing medium 18 or 18 may. be leather, composition material, gum, wax, or the like, to make a tight joint.

The operation of my device very simple and effective. If material is to be dispensed, the cap is removed and a slight pres'air given to the containerb-etore lifting it trom the table or shelf to extrude the desired quantity, or the thimble is pressed while the container is properly held, so as to supply the ointment, grease, or cream to the desired This pressure acting through the stem also causes the plunger to rotatively advance thereon to force material from the nozzle. When the cap, and of course, the plunger-,have advanced so that the edge of the container engages the bottom of the cap, a readjustment of the stem is necessary. This readjustment is accomplished in the manner stated, by giving the cap and stem (or the stem only) a few turns, as will. read ily be understood. The plunger or adjust able distributing member is gradually advanced to its extreme position in the top of the container. Usually the plunger is advanced but once. If, however, the container is to be refilled, this may be readily accomplished by withdrawing the cup and attached parts, including the piston member, and refilling the container by supplying the semi-fluid material. In case a powdery material is used, as tooth or soap powder, the container is preferably refilled by supplying the material in bags or charges, which are In such construcused as required. The bag may be paper or other material., and the entire charge and bag may be placed into the container, with the end towards the nozzle open.

Having now described my invention, what I claim as new and useful, and desirecto secure by Letters Patent, is: I

1. In a dispensing container for semifluids, powders and like materials, the com bination of a body part open at one end and having a discharge nozzle, operatine' member slidably engaging the w lls of said body part, a dispensing member in said body part, and means for varying the relative distance between the dispenc member and the bottom oi the operating member to effect ejection of the contained material from the body part. f

2. in a dispensing container for semifluids, powders and like materials, the combination of a body part open at one end and havin a dischar 'e nozzle an o )eratin member engaging the walls of said body part, a piston n the body part arranged to close the open end for pressing on the cone tamed material, a screw thread d stein exe tending from the operating member and adjustably engaging the piston for varying the distance between the bottom of the operat-in member and the piston.

8. a dispensing container for semi- L fluids, powders and like materials, the combination of a body part havin an open end and a closed end, said closed end being provided with a nozzle, an opera member fitting the open end, a stem resting on the bottom of the operating member and extending into the body part, and a dispensing member operatively carried on said's'tem and adapted to be moved toward the nozz e when the operatingmember is'inade to tclescope with the body part.
