. 7 @laims. This invention relates in general to a device for dispensing liquids from sealed containers and more particularly to an oil dispensing device adaptedto open a sealed oil container filled with a measured charge of lubricating oil and dispense the contents.

The principal object of the invention is to provide the combination of a tamper-proof but readily frangible oil container adapted to coopcrate with a simple; inexpensive funnel spout which fits over and makes liquid-tight locking engagement with projecting parts of the contalner, the funnel spout having means associated therewith for breaking through a wall oi the container to produce an opening for dispensing the oil through the opening and through the spout into the filling opening of an automobile cranlt: case.

An important object of the invention is the provision of such an oil container having looking projections or threads upon a part thereof which cooperate with like projections or threads upon the dispensing device, so that both contamer and device may be readily brought into intimate and liquid-tight locking engagement the contents.

Still another important object of the invention is the provision of a funnel shaped dispenser adapted to loclzingly engage in liquid-tight manner a double seamed end of a scored container and having a plunger adapted to break said score and produce a substantial pouring opening in said container.

Another important object of the invention is the provision of a novel method of dispensing branded or labeled motor oil in sealed, tamperproof containers in an expeditious and economical manner, which method is designed to substantially prevent substitution and adulteration oi the oils and to protect the ultimate consumer against any adulterated and inferior quality.

Numerous other objects and advantages of the invention will be apparent as it is better undenin connection with the accompanying drawing,

discloses a preferred embodiment thereof. Referring to the drawing: Figure 1 is a perspective view showingthe dispensing device applied to an oil container of double seamed end construction;

Fig. 2 is a vertical cross sectional view taken through the device and container of Fig. 1 and showing the plunger after it has accomplished its score breaking function;

Fig. 3 is an enlarged, fragmentary, cross sectional view of the lower part of the score breaking plunger and of the upper part oi the double seamed and scored end of the container;

Fig, 4 is a. fragmentary, cross sectional view of the device, showing the locking projections or 5 threads adapted to engage the projecting parts of the double seam of the container; and

Fig. 5 is a cross sectional plan view taken along the lines 5--5 of Fig. 2.

The preferred embodiment of the invention illustrated in the drawings, presents generally a sheet metal container A and a substantially funnel shaped dispensing device B, also made of metal of somewhat heavier gauge than the container.

Preferably, the container A illustrates a size to hold an exact unit charge of lubricating oil, for example, a quart. It may, however, be made in a number of convenient sizes, for-instance,

half gallon, gallon or five quart size, or any other desired size. It comprises a cylindrical body it,

having a bottom end secured to it by means of a double seam it, or in any suitable liquid-tight manner. A top end is secured to the opposite end of the body H by a like seam it, and has a countersunk flat panel it provided with an annular score line it, located just within the upwardly and outwardly projecting seam it. The con-- tainer is opened by breaking through the score line i5 and displacing the severed part oi the panel it by means of the score breaking plunger hereinafter described in more detail.

The funnel shaped dispensing device 18, preferably spun from seamless brass or copper tubing or cast from aluminum or other suitable metal, comprises a tubular body it of comparatively large diameter at its lower end and at its upper end gradually tapering into a. comparatively small diameter dispensing element or spout it; which, at its outer extremity, defines a restricted beveled opening It. The body it adjacent its large diameter bottom, is cut away to provide a container engaging shoulder 21!, having a recess 22, and thence terminates in a depending flange or collar 23.

In order to provide for a liquid-tight engagement between the funnel dispenser and the con tainer, a sealing means such as an annular gasket i 9, preferably of leather, rubber or other suitable material, is'packed or crowded into the recess 22 of the shoulder 2i.

The depending flange or collar t3 beneath the annular gasket i9 is provided at spaced intervals with elongated inwardly projecting locking threads 2i having inclined or beveled container engaging upper faces 25. Four of these locking threads are preferably employed, leaving :Eour unthreaded portions or recesses it between them.

To cooperate with'these locking elements 26 on the collar 23 of the funnel dispenser B, corresponding locking projections or threads 2? are provided on the container A, by squeezing and projecting outwardly the metal of the top seam id at four spaced points about the periphery of the seam ill. Those looking projections or threads 2i may be produced by a suitable die or squeezer' jaw operation after the double seam iii is formed in the usual manner and without disturbing the tightness of the seam ill.

i'he funnel dispenser B, at one side of the body id, is formed with an apertured extension or bass it which provides a slide bearing for a score breaking plunger. The plunger comprises a square or rectangular stem '29 slidable within the aperture of the boss Eli and having a reduced stud 3! adapted to threadedly engage within a threaded opening in a plunger handle 32. Attached at an inclined angle to the lower end of the stem iii, by means of a screw is a score breaking shoe preierably made from tool steel and having a sharpened knife extension curved to conform to the curve of the score line and aligned relative to the container A to coincide with the score line it (Fig. 3). The body oi the shoe extends inwardly and upwardly from the knife extension M and terminates into a tapered nose.

The funnel dispenseinifi may be made in a number of different sizes and diameters to threadedly fit corresponding sizes and diameters of oil containers above referred to.

When a unit charge of oil of a certain requested brand is to be dispensed into the crank case oi." an automobile at the filling station, the attendant selects a filled, sealed and properly labeled oil container A of the desired size and brand and then inverts a corresponding size dispenser B over it in such a manner that the four seam projections ill of the container coincide with the recesses of the dispenser, and then lowers the dispenser over the container until the top edge of the seam iii engages the gasket or packing iii in the shoulder recess He then rotates the dispenser B upon the container A in a clockwise direction, when the inclined upper faces at of the threads it catch under the seam projections 2i and slide under them until the somewhat resilient gasket it has been tightly drawn down against the seam i3 and forms with the latter a liquid-tight seal which eiiectively prevents the escape of any oil between such seal.

At this stage of manipulation the container, the dispenser and the score breaking plunger are all in the position illustrated in Fig. 3, with the score breaking knife 36 in exact alignment with the score it. A slight downward pressure upon the handle 32 of the plunger causes the knife i l to sever and break through an arcuate portion of the score i Further pressure brings the plunger into;

the position illustrated in Fig. 2, with the inclined body 35 of the plunger shoe further severing and displacing the panel i l along the score line l5 until the panel id is completely severed or remains hanging downwardly (as in Fig. 2) to a small unsevered part of the panel.

The container and funnel dispenser are then tilted to pouring position to dispense theoil through the opening created by the broken panel i i, through the spout ii, and into the filling neck of an automobile crank case or other place of deposit.

o mas In order to permit the rapid draining oi the oil an air vent hole 36 is provided in the body iii of the dispenser, preferably opposite the boss All.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparout 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 oi its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
