Y., assignor to Continental Can Company, Inc., New York, N. Y., a corporation of Application July 13, 1933. Serial No. 680,324 6 Claims. (Cl. 221-23) The invention relates to new and useful improvements in a. can piercing and dispensing device which is particularly adapted for attachment to a hermetically sealed metal can to be used for dispensing the contents thereof.

An object of the invention is to provide a can dispensing device wherein the dispensing device contacts with the double seam of the can, forming a liquid-tight joint therewith, and is rigidly secured to the can by cooperating parts associated with the dispensing device and can, which dis,

pensing device is also provided with a cutter for piercing the end wall of the can for forming a dispensing opening therethrough.

A further object of the invention is to provide a dispensing device of the above type wherein said opening may be first cut and the dispensing device caused to contact with the double seam and the dispensing device subsequently joined m to the can.

These and other objects will in part be obvious and will in part be hereinafter more fully described.

In the drawing:

The invention is directed to a combined can and oil dispensing device for use iii connection with the dispensing of lubricating oilmarketed in hermetically sealed metal cans. The pil is put up by the original dispenser in sealed cans o and is sold in these original packages at the filling stations. The cans may be opened in the presence of the customer and emptied into the chamber where it is to be utilized for lubricating purposes through the aid of the improved dispensing device. The i pensing device includes a New .York

funnel having a body portion to which is attached a cutter used for piercing the can end. The can, after the end is seamed thereto, is shaped or deformed so as to provide spaces in the double seam where the diameter of the can is reduced up slightly. These spaces are of similar shape and disposed in the double seam so that the distances between the recesses are all equal. The body portion of the dispensing device is provided with a recess adapted to receive a resilient gasket which is so disposed as to contact with the outer face of the deformed double seam and provide a liquid-tight joint therebetween. Attached to the body portion is a clamping ring. Said clamping ring is mounted on the body portion so that it to may be rotated thereon. The clamping ring has an opening therethrough and-at spaced intervals there are lugs projecting inwardly or radially of the opening. These lugs are shaped to conform to the recesses in the double seam of the can so that the clamping ring can be lowered over the double seam, placing the lugs just beneath the same. A turning of the ring will cause the dispensing device to be clamped to the can. These lugs on the ring are inclined so that the turning 30 of the ring draws the gasket into tight sealing contact with the deformed double seam.

Referring more in detail to the drawing, the can to which the dispensing device is attached is illustrated at 1 in the drawing, Said can has an end 35 2 secured thereto by a seam which is hermetic or airtight, and this seam is preferably formed by the folding of the metal parts and is referred to as a double seam. The double seam joining the end 2 to the body portion-1 is indicated at 3 in the drawing. After this double seam has been formed, it is then reshaped or deformed so as to provide recesses 4, 5 and 6. These recesses are all similarly shaped and are disposed an equal distance from each other. As shown in the drawing, there are three of these recesses and the centers of the recesses. are 120 degrees apart. These recesses are formed by pressing the double seam inwardly so as to leave the diameter of the can at the recess substantially the same as the diameter of the body of the can, while the diameter of the double seam between the recesses is as usual, i. e. larger than the diameter of the can. This is caused by the double seam being formed between the outwardly projecting flange on the can body and the overhanging flange of the can end.

The oil dispensing device consists of a funnel having a spoutportion 7 which is formed integral with the body portion 8 as it tapers into the spout. The body portion 8 is provided at the open end thereof with the laterally projecting ledge 9. There is a recess in said body portion which is indicated at 10 and located in this recess is a resilient gasket 11. This gasket is adapted to contact with the deformed or reshaped double seam 3 as indicated in Figs. 1 and 4 of the drawing.

Attached to the body portion of the dispensing device are three cutters 12, 13 and 14. These cutters are all similar in construction, and the description of one will answer for the others. Each cutter includes a piercing point 15 formed at the outer end of the cutting blade 16. This cutting blade is shaped so as to cut the can end close to the double seam and along the double seam as indicated at a in Fig. 6 of the drawing. Extending laterally from the blade portion 16 are wings 17 and 18. These wings are each provided vwith an opening 19 and with cutting edges indicated at 20. It is understood that there is a cutting edge leading to the piercing point 15 along the lower edge of the blade 16 as viewed in Fig. 4. These cutting edges merge into the cutting edges 20 formed on the wings 17 and 18. The cutting edges 20 cut the can end along the lines b--b in Fig. 6 of the drawing. The metal cut out by the cutter contactswith the wings and is rolled downwardly and inwardly as indicated at c in Fig. 4 of the drawing. This produces in the can end 3 relatively large dispensing openings which are disposed so that their centers are 120 degrees apart. The cutters are attached to the body portion of the dispensing 'device and project beyond the open end a sufficient distance so that all the openings will be formed before the gasket 11 is brought into contact with the double seam. The cutting of the end is accomplished by placing the can on a solid foundation, then placing the piercing point just inside of the double seam of the end and by downward pressure on the dispensing device the cutters are caused to pierce the end and the metal and form the opening.

Surrounding the projecting ledge 9 is a ring 22. Attached to the ring 22 is a plate 23 which overlies the upper face of the ledge as viewed in Figs. 1 and 4. Said plate is connected to the ring by suitable bolts 24. The ring has an opening 25 therethrough. The edge of the opening 25 is provided with lugs projecting inwardly or radially of the opening. These lugs are indicated at 26. The lugs are disposed with their centers 120 degrees apart and they are so proportioned that when the ring, which is only slightly larger in diameter than the originally formed double seam, is placed over the double seam, bringing the gasket into contact therewith, these lugs pass down through the recesses 4, 5 and 6, respectively. This places the lugs so that the advanced edge 26a the eof is below the double seam. By tuming the ring in the direction of the arrow of Fig. 5, the lug is placed beneath the double seam at the sides of the recesses and will contact therewith and draw the dispensing device downward until the gasket is brought into tight sealing enagement with the double seam. This forcing of the dispensing device downward is accomplished by the inclination of the lugs 26. These lugs cooperating with the double seam between the recesses serve as a means for rigidly attaching the dispensing device to the can. The turning of the ring is to bring about this attachment of tits dispensing device to the can. The body portion of the dispensing device of course does not turn as the cutters are in the holes formed in the end. The longitudinal movement of the dispensing device into tight sealing contact with the double seam is not in any way restrained by the cutters, for the reason that the openings are fully formed at this time and there is little or no cutting of the metal which takes place during the period of clamping the dispensing device to the can.

The cutters of the oil dispensing device are placed in contact with the end of the can and the openings are formed therein while the can rests on a solid support. The ring is then turned to firmly join the dispensing device to the can, after which the can with the dispensing device attached is inverted to a position such as shown for example in Fig. 2 and the spout inserted in the opening 27 of the crank casing 28 for thus dispensing the lubricating oil into the chamber where it is to be used for lubricating purposes.

It is obvious that minor changes in the details of construction may be made without departing from the spirit of the invention as set forth in the appended claims.
