' The present invention relates to dispensing containers for lubricating grease. and the like and has particular reference to an improved container to which a grease gun lubricator may be temporarily attached for filling.

An object of the invention is the provision of a dispensing container of simple construction wherein the fitting for the gun lubricator is made a part ofan inner floating disc which after functioning to dispense the grease may be sealed whereupon it becomes a closure so that the cover which sealed the container during shipment and storage may be entirely discarded after the container is once opened for use.

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 accomp ny drawings, discloses a preferred embodiment thereof.

Referring to the drawings:

Figure 1 is a part side elevation and part sec-' tional view of an initially sealed dispensing container embodying the instant invention;

Fig.2isaviewsimilarto1'ig. lshowingthe cover removed from the container and illustrating a grease gun in position for filling, portions of the gun being broken away and shown in section;

Fig. 3 is a fragmentary detailed view of the container fitting for the gun, showing how this part of the container may be sealed when the gun is removed; and,

Fig.4isa horizontal sectional viewtaken sub stantially alongthe line H in Fig. 3.

As a preferred embodiment of the instant invention the drawings illustrate a sheet metal container comprising a cylindricalbody ll having a bottom closure i2 secured thereto in a suitable seam It. The upper P rtion of the body is preferably enlargedasindicatedat ll andthisenlarged portion terminates in a smooth outwardly (CL eel-41.5)

Depending tabs}! formed on the the cover extend down adjacent the side of the container body andare bent inwardly under the curl II and thus hold th cover tightly in sealing position on the container.

The gun or follower plate or disc I1 is preferably of sunken panel character having a flat bottom wall section it which at its outer edge merges into a flange or side wall section 32 having an cular opening it (Figs. 2, 3 and 4) which is 10- cated in the center of the bottom wall section 3 I. The opening is surrounded by an internally threaded nozzle it which adjacent its bottomend is formed with an inwardly extending flange 31. The metal of the plate bottom wall ll around the opening ll is bent upwardly and outwardly over the flange ll of the nozzle thus forming a suitable scam I! which tightly holds the nozzle in place. In order to prevent i and turning of the nozzle in its seam, spaced indentations 3! are bent edge curl 15 which defines the. mouth of the container.

After the container is filled with its contents a gun or follower plate I! is inserted in the container and the latter is'thereafter closed and sealed with a wver II. The cover is preferably formed with a countersunk panel it which is surrounded by an inverted U-shaped channel section 1i enclosing an annular channel space 12.

The channel retains a resilient sealing gasket 23' formed in the seam which permanently interlock the seam parts.

The nozzle is normally closed with a threaded cap llhaving a raised finger lug 4! formed therein for screwing the cap into closing position, as

shown in Figs. 1 and 3. A resilient gasket 43 is preferably interposed between the cap and the mime seam to provide an airtight joint. Such a container is especially designed for lubricating greases and the like which are adapted to be fllled 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. T. Shere, on Grease gun,

Such a gun preferably includes e. tubular body A,

having at one end a cover B and at the other end a threaded section 0 on which the dispensing nozzle of the gun is secured. Within the gun body there is a piston D secured to a piston rod E which extends through the cover B and terminates in 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 'fi-Dplled to the nozzle of the gun plate ll Ior filling. In such a use the the cover it of the container is first removed by bending back its lugs 25- and lifting the cover outer edge of thus released from its seat on the container. The removed cover may be discarded as it has no further function to perform after the container is once opened. 7

The cap H is then unscrewed from the nozzle 36 and the threaded end of the gun'screwed in place in its stead. The gun may then be readily filled upon drawing the piston D upwardly within the gun cylinder by pulling on the handle F. This movement of the piston creates a vacuum at the opening 35 in the gun plate i'l. Since the entire top of the plate or disc member is exposed to the pressure conditions of the outside atmosphere the latter forces the plate down against the grease in the container. This pressure created on the grease forces it up into the cylinder of the gun; One stroke of the'gun pistonfills the gun and it is thereafter unscrewed from the plate nozzle and its own dispensing nozzle is replaced ready for use.-

Between fillings the cap ll may be screwed in place within the plate nozzle 36 and thereby serves as a reclosure cap for sealing the container against the entrance of air thereinto. The

gun plate thus serves a double function. As the grease is withdrawn from the container the gun plate 41 recedes within the container and always remains in contact with the surface level of the rease.

With such a construction of container the filling of the gun may be performed very rapidly. Since there are no parts other than the gun 1. A dispensing container adapted to receive a piston type lubricating grease gun for filling,

comprising a body member having its upper portion flared outwardly and open at its top, a removable cover member for sealing said container 3 only during shipment and storage, a follower disc disposed within said body member and having a peripheral flange in frictional engagement with tents of the container, and a threaded reclosure or follower plate and its nozzle, its construction I is exceedingly simple and in consequence of this it has been found to be most eiiicient in operation. The bottom of the plate being flat with no parts projecting below it permits the plate to recede to the very bottom of the container so that the container may be entirely emptied of its contents by the use of the gun,

It is thought that the invention and many' of. its attendant advantages will be understood from the foregoing 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.

I claim:

cap for sealing said nozzle in all positions of said disc relative to the container body when said lubricator is not attached thereto in filling position on said disc.

2. A dispensing container adapted to receive a piston type lubricating grease gun for filling, comprising a body member having its upper portion flared outwardly in a section of enlarged diameter terminating in an open top, a removable cover member for sealing said container only during shipment and storage, a follower disc disposed within said body member and having a peripheral flange in frictional engagement with the interior wall of said body member, said flange being offset inwardly below its well engaging portion to provide a peripheral shoulder for reenforcing and strengthening said disc against distortion due to pressure exerted thereon, an upstanding cup shaped nozzle having a flange seamed to said disc above its upper surnozzle in all positions of said disc relative to the container body when said lubricator is not in attached filling position on said disc.
