The present invention relates to dispensing containers for lubricating grease and the like and may be temporarily at- .a dispensing container or simple construction wherein a gun type lubricator may be readily attached to the top of the container for filling without having to move or tilt the container into any special position.

Another object is the provision of such a dispensing container wherein the simple fittings required for the accommodation of the gun lubricator, is made a part of the cover of the container so that the cover may container.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection'with the accompanying drawing, discloses a preferred embodiment thereof.

Fig. l is a part side elevation and part sectional View or a dispensing container emb dyin the instant invention, the view showing a grease gun in position on the container, with portions of the gun broken back and shown in section; and

Fig. 2 is a fragmentary detailed view showing the container closed aiter removal oi'the grease 81m.

As a preferred embodiment or the instant invention the drawing illustrates a sheet metal container comprising a cylindrical body it having a bottom closure i2 secured thereto in a suitable seam it. The upper portion oi the body is preferably enlarged as indicated at id and this onlarged portion terminates in a smooth outwardly bent edge curl as which defines the mouth of the container.

After the container is filled with its contents it is closed and sealed with a cover it. The cover is preferably panel ill which is surrounded by an inverted U-shaped channel, section 88 enclosing an annular channel l9. The-channel retains a resilient sealing gasket 2!! and when the cover is in place on the container body the gasket seats tightly on the body curl l5 while the channel section 88 fits down over the curl. Depending tabs 22 formed on the outer edge of the cover extend down adjacent the side of the container body and are bent inwardly under the curl l5 and thus hold the cover tightl in sealing position on the container.

' has particular reference to a container to which a be used with a standard welded to the cover and also Such a container is especially designed for lubricating greases and the like which are adapted to be filled into and dispensed from the well known grease gun type of lubricator such as disclosed in United States Patent 1,692,423, issued November 20, 1928 to A. "I. Shere on Grease gun. Such a gun preferably includes a tubular body A, having at one end a cove B and at the other end a threaded section C on which the dispensing nozzle of the gun is secured. Within the gun body there is a piston D secured to a rod E which extends through the cover B and terminatesin a handle F.

In the container of the instant invention the gun itself, after its dispensing nozzle end has been removed, is adapted to be applied to the top end of the container and filled without having to move or tilt the container or the gun. For this purpose the cover it of the container is provided with a cylindrical cup shaped dispensing nozzle which is preferably located at the center-of the cover and disposed in an auxiliary countersunk panel to. The nozzle includes a bottom wall section 2? which is preferably spot includes an integral vertical wall section 28 which is formed with internal screw threads which correspond to the threads on the end of the gun and into which formed with a countersunk the end of the gun may be screwed.

The nozzle 25 also includes a long vertically disposed tube 3i which extends down into the interior of the container through aligned holes 32,

83 formed respectively in the nozzle bottom wall I section 2? and in the cover auxiliary panel 26. The tube extends down through the middle of the container body and projects into a, depressed recess 35 formed in the bottom closure 12, the lower end of the tube terminating just short of the bottom of the recess and well below the inner surface or the bottom closure. A flange 36 on the upper end of the tube engages against the nozzle bottom wall section and thus serves as a. stop for holding the tube in proper position relative to the bottom recess. If desired this flange may be welded or soldered to the nozzle to insure permanency of location.

With the sun screwed into position in the threaded nozzle 25, it may be readily filled upon drawing the piston D upwardly within the gun cylinder by pulling on the handle F. This movementof the piston creates a vacuum within the container dispensing tube 3| and thus permits atmospheric pressure within the head space of the container to force down on the surface of the contents and thereby push the contents up through the dispensing tube into the gun. Between such-fillings of the gun the atmospheric air within the container is replenished or built up by small leakage around the nozzle at the spot weldedjoint. 1

A follower plate or disc 31 loosely disposed within the container and resting on the surface of the contents maintains the latter in a'level compact condition and helps force the contents up,

into the dispensing tube. This. plate or disc surrounds and loosely slides on the dispensing tube. One stroke of the gun piston fills the gun which is then unscrewed from the container nozzle and its own dispensing nozzle is replaced ready for use.

.It will thus be seen that such a gun filling operation may be quickly effected ask sometimes required in automobile service stations and the like. Not only is the gun quickly filled but the filling may be done without handling the container in any particular manner. The construction of the container with its dispensing tube extending down into the bottom recess 35 also makes it possible to drain out practically all of the contents without moving or tilting the container.

When the grease gun is not in place on the container the dispensing nozzle 25 is preferably closed with a removable imperforate screw cap 38 (see Fig. 2) which is adapted to be screwed in place within the threaded wall section 28 of the nozzle. The cap is screwed down onto an annular sealing gasket 39 which is retained within the nozzle and this insures a hermetic seal for the nozzle. This cap is also in place during shipment and storage of the container.

It is thought that the invention and many of its attendant advantages will be understood from the f regoing description, and it will be apparent that various changes may be made in the form. construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
