OPENER FOR A DISPENSER Filed Nov. 50, 1960 \II IH'" United States Patent 3,131,831 DPENER FOR A DISPENSER Alexander Dorchak, 1316 McKinley Ava, Yakima, Wash. Filed Nov. 30, 1960, Ser. No. 72,674 Claims. (Cl. '22286) This invention relates to a combination can opener and liquid dispenser.
An object of my invention is to provide such a device having separate air inlet and liquid outlet tubes, each having a separate cutting edge at one end for piercing the can to permit entry of the tubes.
Another object is to provide such a novel device with such tubes mounted in a frame, said frame being further adapted with a rubber gasket which will forrm a seal against the top of the can to prevent leakage around the outer sides of the tubes when they are inserted in the can.
Another object of the invention is to provide the combination described with a cover for the tubes which is hinged to the frame and disposed in a manner to close the tubes at their outer ends and which also is disposed to provide a pad for driving the tubes into the container by hand.
Another object of the invention is to provide a leg on said frame extending downward alongside the can and adapted with means at its lower end for engaging the bottom of the can to hold the tubes in position in the can and to compress the gasket against the can thereby to prevent leakage.
Further objects and advantages of the invention will appear from a reading of the following detailed description with reference to the attached drawings.
In the drawings FIGURE 1 is a side elevation of the combination can opener and liquid dispensing device embodying my invention, and
FIGURE 2 is a front elevation of FIGURE 1, and
FIGURE 3 is a top plane view of FIGURE 1.
in FIGURE 1 reference character It denotes a liquid outlet tube attached together with an air inlet tube 12 in a frame 14. Both tubes '10 and 12 extend an equal length above the frame to their upper ends and extend below the frame, the lower end 20 of the air inlet tube preferably extending below end 22 of the liquid tube as shown. Both tubes 19 and 12 are adapted at their lower ends 20 and 22 with cutting edges for piercing a metal can. Preferably the ends 20 and 22 of the tubes are cut diagonally as shown so that the sharpened edges will progressively pierce and cut the metal can as the tubes are pressed downward into the metal can cover to form holes through which the tubes may be inserted. The tubes and 12 may be spaced apart laterally but preferably are disposed adjacent, side by side, as shown, to make the structure more rigid. The piercing point of each lower edge 26 and 22 is disposed on the inner side of each tube. Thus, when the tubes are adjacent both points will enter the top of the can at approximately the same point.
The tubes 10 and 12 are held by a frame 14 which is attached around the outer sides of each tube. The frame may be welded, soldered, or joined by other suitable means to the tubes. Preferably the apertures in the frame are sealed between the frame and the tubes and a rubber gasket 34 is attached to the underside of the frame around the tubes. Thus, when the tubes are pushed into the can the gasket will form a seal between the can and the frame, around the tubes, thus preventing loss of liquid from the holes pierced in the can by the tubes.
The frame 14 is extended at one end and turned upward to form a lug 24 on which a lid 26 is hinged by a suitable hinge. The lid 26 extends across the upper ends 16 and 18 of thetuhes, as shown. The tube ends 16 and 18 and 3,131,831 Patented May 5,1964
the lid 26 are co-operatively adapted so that the lid will close down over the tubes. A thumb handle 28 may be provided to raise and lower the hinged lid 26.
The frame is extended at its other end to form a leg 34 which is turned down and extends downward along the side of the can. At a length suitable to fit the particular size can on which the device is to be used, the lower end of the leg is turned inward to engage under the lower edge of the can. Thus, the leg provides an outer attachment to the can for holding the tubes securely in the can and also to urge the frame 14 against the gasket to insure a good seal.
The frame, leg, and lug may be an integral member formed from a single strip of material, for instance from a strip of steel. The tubes are made of steel or other suitable material strong enough to pierce a metal can. The hinged cover may be formed of any suitable material such as steel, moulded plastic, or the like.
In one embodiment, the liquid tube is 1 id, o.d. and the air tube is .1 id. and A" o.d. These dimensions are not critical and are recited only for illustration. The air tube may be of smaller diameter than the liquid tube because of the use intended. It is preferable that the liquid flow tube should extend only a short distance inside the can and that the air tube should extend farther into the can toward the bottom. Thus, when the can is inverted for pouring, the liquid will flow from the can down through the liquid tube and air will flow upward through the air tube into the can.
To insert the device in a can, the point of the lower edge of the air tube is placed against the top of the can at a radial distance inward from the upper edge far enough to permit the gasket to lie flush against the top of the can and the leg extends downward along the side of the can. With the lid 26 closed against the tube ends to :form a pad, the tube may be forced downward with the heel of ones hand, piercing the can and cutting a. hole through which the air tube enters. As the tubes move downward the point of the liquid tube pierces the can and the lower edge 22 cuts another hole for the liquid tube. The tubes are then pressed farther down until the gasket lies flush against the top of the can. Meanwhile, the leg 30 has moved downward along the outer side of the can as the frame has moved toward the top of the can. When the tubes are fully inserted, the turned-in portion at the lower end of the leg is snapped under the lower edge of the can. This will urge the frame downward to hold the gasket tight against the top of the can.
The lid may be opened on its hinge and liquid may be poured through the liquid tube 10 by inverting the can. Simultaneously, air will flow into the can through the air inlet tube 12.
The can may be stored keeping the dispenser device in place and with the lid 26 closed to protect the contents. When the contents of the can is exhausted the device may be removed, cleaned, and used again. The device is removed by simply disengaging the leg from the lower edge and withdrawing the tubes.
It is to be understood that the embodiments described herein may be varied somewhat without departing from the appended claims which define the scope of my invention.
