## Abstract

An extruded product formed by extrusion molding and continuing in a longitudinal direction includes: an extruded product body; and a decoration layer provided integrally on a surface of the extruded product body, wherein the decoration layer is provided on a substantially entire surface of the decoration layer by combining an irregular surface pattern and a plurality of linear grooves on the surface thereof, and the depth of the linear groove is deeper than the depth of the irregular surface pattern.

## Claims

### Claim 1

A weather strip for a vehicle, comprising:
a weather strip body including an extruded product body continuously extruded in a longitudinal direction thereof;
lips adapted to secure the weather strip body to a body panel of the vehicle; and
a decoration layer integrated on an exterior surface of the extruded product wherein
the extruded product body, includes a U-shaped trim part and a hollow seal portion,
the hollow seal portion is located on a first side of the trim part,
a cover lip extends from the extruded product body such that the cover lip is located on a side of the extruded product body that is opposite to the hollow seal portion,
substantially an entire surface of the external surface of the decoration layer includes a combination of an irregular surface pattern and a linear groove portion,
the linear groove portion is formed with a plurality of linear grooves,
a depth of the linear grooves is larger than a depth of irregularities on the irregular surface pattern,
the depth of the irregularities on the irregular surface pattern is in a range of 30 μm to 150 μm, and the depth of the linear grooves is in a range of 160 μm to 800 μm,
a width of an opening of the linear grooves is formed in a range of 160 μm to 800 μm, and a width of a root portion of one protruding portion formed by adjacent ones of the linear grooves is formed in a range of 160 μm to 800 μm, and
an interval between adjacent ones of the linear grooves is in a range of 400 μm to 1600 μm.

### Claim 2 (depends on 1)

The weather strip for a vehicle according to claim 1, wherein the irregular surface pattern is one of an embossed pattern and a foamed surface pattern.

### Claim 3 (depends on 1)

The weather strip for a vehicle according to claim 1, wherein the linear groove portions is formed in a mesh pattern.

### Claim 4 (depends on 1)

The weather strip for a vehicle according to claim 1, wherein the linear groove portion is formed in one of a rectilinear pattern and a curvilinear pattern with respect to a longitudinal direction or a transverse direction of the extruded product.

### Claim 5 (depends on 1)

The weather strip for a vehicle according to claim 1, wherein the linear groove portion includes traverse grooves provided in a transverse direction of the extruded product and longitudinal grooves provided in a longitudinal direction of the extruded product that are deeper than the transverse grooves.

### Claim 6 (depends on 1)

The weather strip for a vehicle according to claim 1, wherein the decoration layer is provided on upper surfaces of a trim part and a cover lip of the weather strip body, the weather strip body is formed of EPDM rubber, and the decoration layer is formed of a thermoplastic elastomer.
