Benefits of technology

[0006] The present invention relates generally to a printed film innersole (PFI) and a process for making the same. The present invention provides a PFI and a process for the construction of an innersole for post-insertion into a shoe that can have significant design details added to the bottom surfaces. In one aspect, the invention provides an innersole comprising: a) a first layer made of a printed thermoformable film; and b) a second layer made of a one or more cast cushioning foam materials, wherein the second layer is positioned b

Problems solved by technology

While conventional innersole devices may be suitable for the particular purpose to which they address, they are not as suitable for the construction of an innersole for post-insertion into a shoe that can have significant design details added to the bottom surfaces.
A limitation of conventional innersoles are that they cannot be printed.
Another limitation of conventional innersoles are restriction in colors or other design features.
This is both expensive and labor intensive.

Embodiment Construction

[0010] It is to be appreciated that certain aspects, modes, embodiments, variations and features of the invention are described below in various levels of detail in order to provide a substantial understanding of the present invention. The PFI for shoes according to the present invention substantially departs from the conventional concepts and designs of conventional innersole devices, by providing an apparatus primarily developed for the purpose of the construction of an innersole for post-insertion into a shoe that can have significant design details added to the bottom surfaces.

[0011] In one aspect, the present invention provides a PFI device for shoes that overcomes the shortcomings of the conventional innersole devices. In one embodiment, the PFI present invention comprises: a thermoformable film, a printed film, a formed shell and a cast cushioning foam materials. In one embodiment of the invention the thermoformable film is a thermoplastic film. In a preferred embodiment of ...

Abstract

The present invention relates generally to a printed film innersole (PFI) and a process for making the same. The present invention provides to a PFI and a process for the construction of an innersole for post-insertion into a shoe that can have significant design details added to the bottom surfaces.

Description

RELATED APPLICATION [0001] This application claims the benefit of priority under 35 U.S.C. §119(e) from U.S. Ser. No. 60 / 562,893, filed on Apr. 16, 2004, the contents of which are incorporated herein by reference in its entirety.FIELD OF THE INVENTION [0002] The present invention relates generally to a printed film innersole (PFI) and a process for making the same. More specifically the present invention related to a PFI and a process for the construction of an innersole for post-insertion into a shoe that can have significant design details added to the bottom surfaces. BACKGROUND OF THE INVENTION [0003] The use of innersoles (a.k.a., insoles) for footwear, e.g., shoes, is well known in the art. Typically, innersoles are made of cast polyurethane both single density and with various cast elastomer drops, e.g., ethylene vinyl acetate (EVA) thermoformed insoles and other various thermoformable materials, i.e., thermoplastic materials. Other various cushioning materials are also utili...
