U.S. Pat. No. 3,995,544 to D. Gray Farley describes a utensil for the separation of liquid from subdivided solid comestibles, typically, for the separation of oil and liquid from canned meats such as tuna and the like. The device comprises a generally cup-shaped member having a cylindrical wall conforming to the internal diameter of a standard can size and an end, circular wall which is perforated to provide permeability to liquid while blocking passage of subdivided solid comestibles. The side walls distally support tab means which project radially outwardly from the side walls to provide for grasping of the press whereby the press can be inserted into a can, compressed against the contents therein and then rotated into an inverted position to permit unimpeded drainage from the can.
U.S Pat. No. 4,355,574 to James M. Bond and Robert P. Dail, describes a liquid-expressing tong-like implement for removing liquid from a solid can of food product containing solid food product immersed in liquid formed as a pair of scissor-like elongated arms pivoted together and having a finger at handle-forming rear end portions thereof and front end portions at the ends opposite said finger loop formations providing loop-shaped jaw formations. One of the jaw formation loops has a generally straight rod-like front leg portion extending transversely of its associated elongated arm, and a flat platen member sized to fit into an opened food product can to exert pressing forces onto the solid food product is pivotally coupled to the rod-like leg portion for pivotal movement about that transversely arranged leg portion. The other of the jaw formation loops defines a flat portion to engage the bottom of the opened can.
U.S. Pat. No. 4,860,647 to James L. Kerslake, relates to the present invention to an improved can draining implement including two handles privotably attached together. One handle has a can supporting plate which faces a plunger on the other handle. The plunger has an angled face designed to cause liquid being drained from the can to flow to one side. Furthermore, the plunger has embedded therein a magnet designed to hold the lid of the can after draining had been accomplished.
U.S. Pat. No. 5,272,968 to Patricia M. Keville and Thomas J. Murphey, Jr., describes a hand utensil for draining liquid from canned foods, or for removing can lids after opening and of the type having a base with a grip which contains a pass through hole containing a spring in which the T shaped handle passes through when compressed causing the magnetic plate to place pressure on a lid of an opened can, and when uncompressed the T shaped handle will return to its original position causing the can lid to be removed from the can attached to the magnetic plate. The utensil is made of an inflexible material so that it is strong enough to safely provide the required pressure.
U.S. Pat. No. 5,272,969 to Brian McDonald, describes a canned material compressing and liquid extracting device including a pair of elongated lower and upper handles and a hinge pivotally attaching adjacent respective one ends of the handles together permitting the handles to be moved toward and away from each other between a closed position and an opened position. The device also includes a land portion mounted on the lower handle for seating a container which has an open top end and encloses a material to be compressed and a piston member pivotally mounted to the upper handle for insertion into the open top end of the container so as to overlie a severed lid of the container for applying a force on the severed lid sufficient to compress the material in the container and extract liquid therefrom as the upper and lower handles are moved relative to one another from the opened position toward the closed position. The device further includes a linkage extending between and connected with the piston member and the one end of the lower handle to cause pivoting of piston relative to the upper handle in a direction opposite to the direction of pivoting of the upper handle relative to the lower handle as the handles are moved toward and away from one another so as to maintain the piston in a predetermined alignment with the container for facilitating uniform compressing of the material in the container.
U.S. Pat. No. 5,501,144 to Keith Bryson describes a hand held press used to remove the liquid packing fluids in a can of food by biasing the lid of the can against the contents of the can. The press includes an upper pressing element and a lower pressing element. The upper pressing element has a perforated region that acts as a strainer. The perforated region is advanced against the lid and into the can, wherein displaced packing fluids are collected within a receiving area defined within the perforated region. A pour spout then allows the collected fluids to be removed in a controlled manner. The lower pressing element retains the can in a predetermined orientation as the can is being pressed. Accordingly, the angle at which the displaced fluids will pour is controlled by the manipulation of the press and the can of food held firmly within the press.
U.S. Pat. No. 5,590,590 to Edward Zammit describes an implement for separating the liquid medium from the solid contents of canned foodstuffs, e.g., canned tuna fish, having two arms pivotally connected by a hinge, e.g., a pivot pin, one arm ending in a compression plate the other ending in a can receptacle, one or both arms being bent to allow substantial alignment of the compression plate and can receptacle, is described. The opposite ends of both arms are handles; and the compression plate is sized so as to fit into the can containing foodstuffs and allow liquid to escape therefrom when the contents are compressed. The thickness of the compression plate is also sized so that a portion protrudes from the top of the can after the contents thereof have been compressed, so that it can be used to strike a solid surface, generating a further compressive force.
U.S. Pat. No. 5,706,721 to Hamilton E. Homes describes a food can drainer for a can containing a solid foodstuff and packing fluid is foraminous sheet sized to fit an end of the can when the can is open at that end, with holes in the sheet sized to retain the foodstuff in the can, yet allow flow of the packing fluid when the can is tipped to decant the fluid. For typical cylindrical cans such as tuna or salmon, the drainer is a perforated disc sized to fit snugly in the can so that, when the can is inverted, packing fluid flows out of the holes in the disc and manual pressure can be exerted to squeeze out excess fluid. The holes are positioned so that the packing fluid forms a stream in the approximate center of the drainer. The drainer can be installed in the can during or after canning.
U.S. Pat. No. 5,826,502 to Bruce B. Wade describes a press-like device, for the forcing of canning liquid from solid food in a can of a type having a lid arranged to be severed to effect the opening of the can, including a first member having a convex part and a concave part, a lower surface of the convex part including a gripping unit and an aperture at a free end of the concave part, the first member including a slot at a region of transition between the convex and concave parts. The device further includes a lid engagement element, the same inclusive of a magnet, the lid engagement element dependent from a free end of the concave part of the member. The device further includes a second member having a concave part and a convex part, the second member pivotally secured to the first member at a fulcrum point passing through the slot of the first member and passing through a region of transition within the second member between the concave and convex parts thereof, the convex part including, at a free end, elements for locking within the aperture of the free end of the convex part at selectable distances between the respective free ends of the respective parts of the first and second members. The device yet further includes a can base element integrally dependent from a free end of the concave part of the second member of the device, the base element disposed oppositely to the lid engagement element.
Notwithstanding the prior art, the present invention is neither taught nor rendered obvious thereby.
