Abstract
A dispenser includes an upper member having a slot and a lower member attached to the upper member thereby forming a housing, the lower member having an outer surface; a stack of sheets assembled in a fan-fold configuration disposed in the housing; and a polymeric holding film having a first surface attached to the outer surface of the lower member. The holding film having a flexural modulus less than about 50 MPa, as measured according to ASTMD790 standard, and a roughness parameter, Ra of less than about 1 micrometer, as calculated according to ASME B46.1 standard.
Claims18
A dispenser configured for temporary attachment to a work surface, the dispenser comprising:
- an upper member having a slot and a lower member attached to the upper member thereby forming a housing, the lower member having an outer surface;
- a stack of sheets assembled in a fan-fold configuration disposed in the housing;
- and
- a polymeric holding film having a first surface and a second surface, the first surface attached to the outer surface of the lower member by an attachment mechanism selected from the group consisting of mechanical based attachment mechanisms and adhesive based attachment mechanisms, wherein the attachment mechanism is located centrally on the holding film and the area of the first surface is larger than the size of the attachment mechanism, the polymeric holding film having a flexural modulus less than about 50 MPa, as measured according to ASTMD790 standard, and a roughness parameter, Ra of less than about 1 micrometer, as calculated according to ASME B46.1 standard, and the second surface of the polymeric holding film disposed so as to be placed in direct contact with a work surface.
