Abstract
An aluminum foil safety fixture with a slide plate to gradually separate aluminum foil in a safe and convenient cutting process. It eliminates the need for a steel cutting blade. It is comprised of a slide plate with arched pressing edges, fitted to a push unit that is installed with at least one pair of slide pressing rollers, and movably assembled in a slide rail of a main unit base. The supporting plate extends from the main unit base and the clasp plates can be directly fitted to a wall of an aluminum foil packing box, so that the aluminum foil can be pulled to a certain length, rested on the top of the slide rail, then the push unit is pushed lightly over the aluminum foil. This will depress the aluminum foil and ultimately separate it into two pieces.
Claims1
An aluminum foil safety fixture for separating a piece of aluminum foil from a roll of aluminum foil in a packing box, the safety fixture comprising:
- a) a main unit base having:
- an elongated slide rail with an upwardly opening, inverted “T” shaped rail opening extending therealong, the elongated slide rail having a pair of flanges facing toward each other and extending along a length of the elongated slide rail on opposite sides of the rail opening, and a pair of rail wall ribs facing toward each other and spaced from the pair of flanges and from each other so as to form a space therebetween;
- a supporting plate extending downwardly from the elongated slide rail;
- and at least one clasp plate extending downwardly from the elongated slide rail and spaced from the supporting plate such that a wall of the packing box may be accommodated therebetween so as to removably attach the main unit base to the packing box;
- b) a slide plate made of plastic material and extending through the inverted “T” shaped opening exteriorly of the elongated slide rail and through the space between the pair of rail wall ribs, the slide plate having oppositely facing convexly arcuate pressing edges, the pressing edges extending into the inverted “T” shaped opening, the slide plate further including a slide block engaging sides of the rail wall ribs facing away from the pair of flanges;
- and,
- c) a push unit attached to the slide plate and located outside of the elongated slide rail, the push unit comprising an upper pushing surface and a hollow interior, a plurality of pressing roller assemblies mounted to the push unit, each roller assembly having a rolling shaft and two rollers located on opposite sides of the slide plate, such that two rollers roll on surfaces of the pair of flanges facing away from the rail wall ribs, a spring acting between the push unit and each rolling shaft urging the pressing roller assemblies away from the hollow interior of the push unit, and protruding shoulders engaging the rolling shaft to prevent disengagement of the roller assemblies from the push unit.
