Abstract
A freezer liner construction having improved selected foam adhesion characteristics. The outer surface of the liner is provided with a laminated release film which prevents adhesion of the foamed-in-place insulation thereto for optimum stress relief relative to thermal expansion and contraction of the liner relative to the foam and cabinet. One or more adhesion strips are provided on the release laminate to provide localized bonding of the foam to the liner for improved structural integrity in the cabinet structure.
Claims15
A liner construction for use in a cabinet having insulation foamed-in-place about the outer surface of the liner, comprising:
- a liner formed of synthetic resin;
- a foam release material covering substantially the entire outer surface of the liner;
- and securing means attached to said foam release material at preselected positions for securing the foamed-in-place insulation to the foam release material at said preselected positions whereby said foamed-in-place insulation is effectively secured to the liner at said preselected positions.
A liner construction for use in a cabinet having insulation foamed-in-place about the outer surface of the liner, comprising:
- a liner formed of synthetic resin;
- a laminate sheet secured to the outer surface of the liner having an outer layer formed of foam release material;
- and means attached to said outer foam release layer for securing foamed-in-place insulation to preselected portions of said foam release material whereby said foamed-in-place insulation is effectively secured to the liner at said preselected positions.
