Abstract: An invention that raises the tops of beverage cans at an angle that makes the drinking process easier, cleaner, more practical and safer (as in the case of drinking a soft drink while driving an automobile) in which one end of the can top that contains the scored oval opening is raised above the rim top of the can in a slanting wedge or circular shape that slants down to the opposite side allowing the can to be raised to a higher degree angle where it does not come in contact with the nose of the person drinking and reduces the angle the head is tipped backward as the drink is being consumed. Also the new top is raised in just the right amount so that it will fit into the concave bottom of an existing can without making contact, thus allowing for the stacking of cans on top of cans in six pack units. For twelve pack or larger packs, the invention includes spacers that allow for stacking packages on top of packages.

Abstract: The printing or digital displaying of sets of two numbers in consecutive order, in one of three configurations that along with the existing number, printed or designed, form in proportion two of the three sides of a 3 by 4 by 5 increment 90-degree right-angled triangle, or any other right triangle where the three sides form increments in whole numbers or whole numbers and simple fractions, on or in all types of measuring devices that measure distance or angles in some form of increments including tape measure blades, optical reader tape measures, rulers yard sticks etc. The printing or digital display of the cosine formula for finding angles when two sides of a triangle are known and indicating the cosines for angles of 90 degrees or less.
