BClaims.

The present invention relates to liquid dispensing devices and has particular reference to the opening of sealed receptacles or cans containing liquids such as lubricating oil and to the dispensing of the liquid contents, the opening action at the same time mutilating both end and side walls of the receptacle to prevent its re-use. In some respects the present invention is an improvement upon the Nicholls United States Patent No. 1,970,573, issued August 21, 1934, upon Liquid dispenser.

In the liquid dispenser of the Nicholls patent an 011 can is opened by puncturing the top or end wall of the can. After the can was emptied it was found that the entire top might be cut off from the body and the body refianged, filled again with oil and a new top or end member seamed in place. This was, 01' course, a case of substitution for the marking on the outside of the can giving the original oil companys name, etc., was no longer correct as in fact a poorer grade of oil was palmed oil on the public who was deceived in thinking it was obtaining the original high grade 011.

In some cases unscrupulous jobbers of oil succeeded in cutting away only suflicient of the double seam which joined the can cover with the can body of emptied cans so that the punctured end could be lifted off of the can without mutilating the flange of the can body. Here again an inferior grade of oil was sealed into the can, it being merely necessary to apply a new can cover.

An object of the present invention is the provision of a liquid dispenser which is adapted to' receive sealed liquid filled containers such as cans of lubricating oil and to hold them while opening and venting by a simple movement of the opening elements, after which the opened can still held in the holder, is emptied of its contents by a simple tipping action of the holder, the opening and venting operation of the dispenser simultaneously mutilating not only the end of the can but also the side wall of the body so that such,

a can is rendered useless for refilling, it being impossible to reclose such a mutilated can without detection.

A further object of the invention is the provision of liquid dispensers of the character described having pouring spouts and a can opener element operated at the time the can is opened to not only cut through the end wall of the can to permit dispensing of the liquid but also to pass on and into the side wall so that the can body is mutilated, this being done without any extra operation and without detracting in any manner from the opening and dispensing action of the device.

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 drawings, discloses a preferred embodiment thereof.

Referring to the drawings:

Fig. 6 is a perspective view of a portion of the opening elements of the device and their mountings, parts being broken away.

A preferred embodiment of the invention such as is illustrated in the drawings comprising a dispensing holder ll open at the top and closed by a bottom member l2. This holder is preferably provided with a handle I! formed with a horizontal straight upper section I disposed in a horizontal line passing along the upper rim of the holder. The wall of the holder ll adjacent its upper rim is cut away at opposite sides as at l5 (Figs. 1, 2 and 3) and a sealed receptacle or can l6 containing a liquid such as lubricating oil may be placed into the holder, the openings l5 permitting holding of the container by the fingers during such positioning.

A pouring spout II is provided having a pair of side wings 22 at the bottom of the spout which are secured to the exterior front wall of the holder Ii. This pouring spout extends upwardly and at an angle and isslightly conical in form. The upper end of the spout terminates in a tubular mouth or discharge opening and below this the spout is cut away along its top to provide a 65 clearance or transverse opening It for an openin: lever 2.

The opening lever is preferably formed with s acedrearlessllconnectsdatthebackina Fig- It is when the opening lever II is in its open The fairly snug fit within the holder as it sgt restsliponthebottomlf,itslmperedgebeing substantiallyin line withthetoprimof the holder. Inthisinsertedpositiontheopening and venting of the can is effected by a shifting of the lever 24 as it is brought down into its closed or horizontal position over the can.

A hollow puncturing munber or cutter II (Figs. 2 and 6) is provided for cutting a dispensing opening in the can end and also for mutilating its side wall. This cutter comprises spaced side walls 38 joined in front by a curved 40 blade I! which terminates in a depending piercing point It. In the rear the side walls 30 are Joined by a curved web I. The hollow cutter fl is located between the front spaced legs 20 of the opening lever and is held in fixed position between these legs by rivets or pins ii. The lower edges of the cutter side walls are sharpened or beveled as indicated at 42 (Figs. 3 and 5).

The lever It also carries a vent blade II which is locatedbetween the rear legs 28 of the opening lever and which is held in place by pins I! seatedinthespacedlegwallsll. Thisvent blade is provided with a V-shaped pointed and beveled depending piercing edge I! which proiects below the opening lever, the blade being also out through with a transverse opening '4. Its use will be made apparent later.

The piercing edge of the vent blade II is enelosedmostofthetimeandforthismlrp e there is provided a protecting shield it formed with side walls I? which normally extend down below the piercing point. These side walls at the front are pivotally mounted on a pin it carried in the spaced legs of the opening lever.

when shielded the parts are in the position illustrated in Figs. 1, 2 and 6, the shield frame being held down against the lever 24 by a spring I. The spring is coiled around the pivot pin it and one end of the spring is inserted in an opening '2 (Figs. 5 and 6) formed in the upper wall of the shield member ll. The opposite end extends over and engages a pin it held in the spaced legs II of the opening lever.

After the can I! is inserted within the holder II the opening lever is brought down from its vertical position (fig.

just inside and adjacent its side wall.

l 'urther depre-ion of the lever forces the cutter ll into the can wall the edge of the piercing member II and the two side cutting edges 42 cutblade 81 in addition to cutting into the can end has passed entirely through the side wall of the can and has bent out a portion of the wall. During this cutting movement the web 89, engaging the severed section of the can end after it is out by the cutting edges l2, bends back the severed can end section into the can. Fig. 4 illustrates the dispensing opening formed in the top of the can, this being designated by the numeral I, a partofthewall asat i2 beingbentbackbythe web II. The opening II, it will be observed, is bounded on the side by lines of cut designated by the numeral it, these being where the cutting edges 42 of the cutter entered the can end.

The curved blade 81 of the cutter is an arc of a circle having as its center the center of the pin I i this being the pivotal center on which the lever 24 moves. Accordingly when the lever is brought down into the position illustrated in Fig. 5 the curved shape of the blade 31 causes its piercing point It to pass from the top end opening OI directly into the side wall of the can adjacent its Junction with the top end. In. passing into and through this side wall a mutilated opening it (Figs. 4 and 5) is produced. This opening destroys the usefulness of the can body and prevents re-use of such a body wall.

As the opening lever it approaches the end of its downward stroke but prior to coming into its final position of Fig. 5, the bottom rounded edges of the side walls ll of the vent shield 58 strike against the top of the can and are stopped while the continued movement of the opening lever causes the shield to pivot on the pin I. The piercing point of the vent blade 5| engages and enters into the wall of the can during such continued movement.

A vent opening I! (Fig. 4) is thus produced in the can top on the opposite side irom the dispensing opening II. The vent blade II remains in this opening (Fig. 5) as long as the opening lever is in its closed position and this is the position for dispensing. By reason of the opening '4 in the blade, air passes from the outside into the opening and thence enters into the can above the liquid.

The dispensing device with its confined and opened can may now be lifted by its handle II, the handle end of the opening lever 24 being preferably held down against the handle part II. Dispenser and can are then tipped into the position illustrated in Fig. 5 for the discharge of the can contents.

The liquid flowing from the can passes out through the hollow cutter II and through the dispensing opening ii in the can top and thence through the pouring spout 2| out through its discharge end where it is directed as desired. Some of the liquid may even pass through the mutilated opening M in the side wall of the can although the curved blade substantially closes the opening. Any liquid passing through the opening drops into the snout and eventuallv flows therefrom with the body of liquid issuing through the dispensing opening During this discharging of liquid frbm the can the air is entering through the opening 54 of the vent blade 5i as has already been explained. This air passes through the vent opening 65 in the can top wall and displaces the liquid as fast as it is drawn od. An easy dispensing action results.

Following a dispensing action and emptying of the can, the opening lever is returned to its non-operating position within the pouring spout. The empty can may then be lifted out of the holder, easy grasping of the can by the fingers being possible by reason of the clearance openings IS in the side walls of the dispenser holder as has already been explained. The ra ged can wall edge which is pushed out by the blade 31 at the making oithe mutilated opening 68 passes into a clearance slot 61 (Figs. 1 and 2) which is formed in the front wall of the holder H and this clearance opening now permits lifting of the emptied can from its seat within the holder without interfering with the free sliding movement of the same.

By reason of the construction of the curved and fixed cutter member 35 the desired kind of dispensing opening 6! is formed with a single stroke of the lever 24 and at the same time and without further movement of the blade 31 .other than its body movement by reason of the change of position of the lever'fl. In other words without'further effort and in a single simple movement the operator opens the sealed can for easy dispensing of its contents and mutilates it Feyond re-use. Dispensing of its liquid contents is then a simple matter after which the can is removed from the holder in the regular way.

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 I merely a preferred embodiment thereof.
