Abstract
A wiping material dispenser in the form of a spool from which the material can be unwound in a strip. The dispenser includes a housing and a cutting system for cutting the strip pulled manually by a user. The cutting system includes a flexible blade and at least one tooth mounted on a front side of the housing. The flexible blade includes at least one slot positioned opposite the at least one tooth. The flexible blade can be deformed under the pressure of the strip, when a user pulls on the strip from the front side of the housing, so that the at least one tooth protrudes through the at least one slot, comes into contact with the strip pressed onto the flexible blade and tears the strip at a pre-cut line.
Claims14
A dispenser of wiping material, the wiping material in a spool that is unwindable in a strip, the dispenser comprising:
- a housing and a cutting system, the cutting system for cutting of the strip when the strip is pulled manually by a user, wherein:
- the cutting system comprises a flexible blade and at least one tooth, the flexible blade and the at least one tooth being mounted on a front side of the housing,
- the flexible blade includes at least one slot positioned opposite the at least one tooth,
- the flexible blade is deformable under pressure of the strip, when the user pulls the strip from the front side of the housing, so that the at least one tooth projects through the at least one slot, contacts the strip pressed onto the flexible blade, and tears the strip, and
- the flexible blade has at least one end including an oblong hole, the oblong hole receiving a fastening element integral with the housing, the flexible blade thus being able to slide laterally while deforming under the pressure of the strip.
A dispenser of wiping material, the wiping material in a spool that is unwindable in a strip, the dispenser comprising:
- a housing and a cutting system, the cutting system for cutting of the strip when the strip is pulled manually by a user, wherein:
- the cutting system comprises a flexible blade and at least one tooth, the flexible blade and the at least one tooth being mounted on a front side of the housing,
- the flexible blade includes at least one slot positioned opposite the at least one tooth,
- the flexible blade is deformable under pressure of the strip, when the user pulls the strip from the front side of the housing, so that the at least one tooth projects through the at least one slot, contacts the strip pressed onto the flexible blade, and tears the strip, and
- a pivoting roll fastened to the housing on the front side, upstream of the cutting system in a strip exit direction, to guide the strip from the spool to the flexible blade, wherein the roll comprises sections of reduced diameter, and the flexible blade comprises tabs disposed protruding in the sections of reduced diameter of the roll.
A method comprising:
- using a dispenser of wiping material, the wiping material in a spool that is unwindable in a strip, the dispenser comprising:
- a housing containing the wiping material and a cutting system of the strip, wherein:
- the cutting system comprises a flexible blade and at least one tooth, the flexible blade and the at least one tooth being mounted on a front side of the housing,
- the flexible blade includes at least one slot positioned opposite the at least one tooth, the flexible blade has an end including an oblong hole, the oblong hole receiving a fastening element integral with the housing,
- pulling the strip from the front side of the housing, so as to deform the flexible blade under pressure of the strip thereby causing the end of the flexible blade to slide laterally relative to the fastening element, the at least one tooth projecting through the at least one slot, contacting the strip pressed onto the flexible blade, and tearing the strip.
