its base two pressure points in the form of small protrusions 324c located on the inner edge of each branch 324b and designed to snap over the bottom surface of the lever arm 312 protrusions 324c permit the lever arm 312 to stay locked thereon when reversed into storage position fig2 and 23 although not shown the protrusions 324c could alternatively lock into lateral cavities situated on both sides of lever arm 312 to permit the side grip 324 39 to flip over parallel to the upper surface of the lever arm 312 as shown in fig2 provisions are made for a 34 living hinge 34 327 situated along the apex of a raised triangular shaped tip 327a integrated to the upper proximal edge of the frame 312a fig2 in addition the proximal end section of frame 312a is also configurated to match the front and back mating portions of grip 324 39 to permit close abutment of grip 324 39 to lever 312 in the folded position as a result the rectangular recess 333 fig2 formed between the anchoring bridge 328 and the side grip 324 39 can conveniently fit below the lower rectangular edge 312c of the frame 312a while the tapered upper edge 324d of the side grip 324 39 can fold over into the mating tapered upper surface 312d of the frame 312 such arrangement detailed in fig2 provides the side grip 324 39 with a full 270 u00b0 rotation to permit it to assume its storage position while also permitting the lever arm 312 to rotate 180 u00b0 to effect perforation of the can top when the grip support 324 39 is in vertical position and mounted on the can rim as mentioned.
