Problems solved by technology

However, these materials have limitations regarding the relative movement of the device and the types of surfaces that can be used
For example, using a ferromagnetic material as an attachment means necessarily limits the display surface to a metal-based material

example

[0051] The following polymeric films were tested for flexural modulus and surface roughness according to the test methods described above.

[0052] Table 1

[0053]

[0054] The retention films listed in Table 1 were then subjected to testing with tension using an Instron machine with a slide speed of 20 inches per minute. 3-inch diameter round membranes of each type are attached using 1-inch square double-sided tape to a surface similar to figure 1 3-inch round lower member of the dispenser shown in. A 1" wide piece of tape is attached to the top area of ​​the dispenser, the tape serves as the lead for the Instron clamp. Dispensers with retaining film are placed on different work surfaces (eg oak planks). The three types of work surfaces tested (all wood-based) included: (a) chah-cut oak plywood, (b) oak plywood with polyurethane coating, and (c) oak plywood with lacquer coating. Dihedral cut oak plywood is plywood in which the oak is sliced ​​tangentially along the gro...

Abstract

The invention discloses a dispenser including 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; anda 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.

Description

[0001] Cross References to Related Applications [0002] This application claims U.S. Provisional Patent Application Serial Nos. 60 / 830764 and 60 / 830979, filed July 14, 2006, 60 / 851,622, filed October 13, 2006, and 3 dated patent application 60 / 864,169, each of which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to attachment systems and to dispensers for use in conjunction with attachment systems. When the attachment system is attached to the dispenser, it allows one-handed removal of a sheet disposed in the dispenser. Background technique [0004] There are many devices that can provide suction between an article and a surface. For example, suction cups can be used on surfaces such as windows and doors to display decorations or to hold items in desired positions. A typical suction cup has rounded edges and a concave surface intended to come into contact with a display surface once the suction cup is assemble...
