Abstract
Abstract A method of manufacturing a plastic shell by providing a printed applique having a central portion with a peripheral skirt portion having an edge, then inserting the applique into the recess on a first side of a mold. The skirt of the applique has a length greater than the depth of the recess, so that the edge of the skirt extends beyond the parting line. The second side of the mold is closed to enclose the recess, and has a second recess that receives the edge of the skirt on the second side of the parting line. Plastic material is injected into the closed mold pressing the applique against the first side, and providing a bezel with an applique that covers the exterior of the front portion, and which extends to cover the skirts beyond the parting line.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
182 words
A method of manufacturing a plastic shell comprising the steps: providing a printed applique having a central portion and a skirt portion depending from the periphery of the central portion and terminating at an edge; inserting the applique in a first mold portion having a first recess sized to receive the applique, the first recess defined by a peripheral wall terminating at an line coincident with a parting line of the mold; the skirt of the applique having a length greater than the depth of the first recess, such that the edge of the skirt extends beyond the parting line; moving a second mold portion into a closed position in contact with the first mold portion to enclose the recess, the second mold portion defining a second recess registered with the skirt of the applique such that a portion of the skirt is received in the second recess when in the closed position; and injecting plastic material into the first and second recesses to a region between the applique and the second mold portion, including pressing the applique against the first recess.
Claim 2
Independent Claim
182 words
A method of manufacturing a plastic shell comprising the steps: providing a printed applique having a central portion and a skirt portion depending from the periphery of the central portion and terminating at an edge; inserting the applique in a first mold portion having a first recess sized to receive the applique, the first recess defined by a peripheral wall terminating at an line coincident with a parting line of the mold; the skirt of the applique having a length greater than the depth of the first recess, such that the edge of the skirt extends beyond the parting line; moving a second mold portion into a closed position in contact with the first mold portion to enclose the recess, the second mold portion defining a second recess registered with the skirt of the applique such that a portion of the skirt is received in the second recess when in the closed position; and injecting plastic material into the first and second recesses to a region between the applique and the second mold portion, including pressing the applique against the first recess.
Claim 3
Dependent Claim
25 words
The method of claim 1 wherein providing the applique includes providing a flat sheet of plastic and thermoforming the sheet to provide the skirt portion.
Claim 4
Dependent Claim
13 words
The method of claim 2 including cutting the applique to define the edge.
Claim 5
Dependent Claim
43 words
The method of claim 2 wherein the applique has a corner at which the skirt forms an angle, and wherein thermoforming the sheet includes forming expandable ridges in the skirt, such that the corner of the skirt may expand to fill the recess.
Claim 6
Dependent Claim
28 words
The method of claim 1 wherein pressing the applique against the first recess includes extending an intermediate portion of the skirt laterally beyond the edge of the skirt.
Claim 7

The method of claim 1 wherein pressing the applique against the first recess includes forming an edge along an intermediate portion of the skirt.
Claim 8
Dependent Claim
16 words
The method of claim 6 wherein the edge corresponds to the parting line of the mold.
Claim 9
Dependent Claim
153 words
A bezel comprising: a central panel portion having an exterior surface facing a first direction and an interior surface facing an opposite second direction; a skirt depending from a periphery of the panel portion and angularly disposed therefrom at least somewhat toward the second direction; the skirt having a major first surface facing away from the central panel portion, and at least slightly toward the first direction; the skirt having a second surface meeting the first surface at a parting line edge, and facing away from the central panel portion and at least slightly toward the second direction, such that the first and second surfaces have draft angles in opposite directions; and a single sheet of printed material covering and defining the exterior surface of the central panel portion and extending over the first surface of the skirt, and covering and defining at least a portion of the second surface of the skirt.
Claim 10
Dependent Claim
153 words
A bezel comprising: a central panel portion having an exterior surface facing a first direction and an interior surface facing an opposite second direction; a skirt depending from a periphery of the panel portion and angularly disposed therefrom at least somewhat toward the second direction; the skirt having a major first surface facing away from the central panel portion, and at least slightly toward the first direction; the skirt having a second surface meeting the first surface at a parting line edge, and facing away from the central panel portion and at least slightly toward the second direction, such that the first and second surfaces have draft angles in opposite directions; and a single sheet of printed material covering and defining the exterior surface of the central panel portion and extending over the first surface of the skirt, and covering and defining at least a portion of the second surface of the skirt.
