Abstract
A method of manufacturing a cover for a spa includes the steps of vacuum molding a first shell member and a second shell member, bringing the first and second shell members into registration with one another to define a hollow cavity therebetween, and injecting a foam into the hollow cavity, wherein the foam is configured to bond with the shell members to create a unitary structural part that provides increased strength and rigidity.
Claims14
A method of manufacturing an article for a spa, comprising the steps of:
- providing a first shell member;
- providing a second shell member;
- bringing the first shell member and the second shell member into nesting relationship to define a single hollow interior cavity;
- and
- disposing a foam in the hollow interior cavity;
- wherein the foam is configured to bond with interior surfaces of the first shell member and the second shell member to create an integral structure;
- and,
- wherein the foam is configured to expand to seat and hold a male arcuate projection of the first shell member into a female arcuate recess of the second shell member.
A method of manufacturing a cover for a spa, comprising the steps of:
- vacuum forming a first shell member from an acrylic material;
- vacuum forming a second shell member from an acrylic material;
- bringing the first shell member and the second shell member into nesting relationship to define a single hollow interior cavity;
- and
- locating a high density, closed-cell foam in the hollow interior cavity;
- wherein the foam bonds with the first shell member and the second shell member to create an integral structure;
- and,
- wherein the foam expands to seat and hold a male arcuate projection of the first shell member into a female arcuate recess of the second shell member.
A method of forming a spa cover, comprising:
- vacuum forming first and second shell members configured to form an interior cavity when aligned;
- disposing a foam within the interior cavity;
- wherein the foam holds a male arcuate projection of the first shell member into a female arcuate recess of the second shell member;
- and
- bonding the foam to the first and second shell member to form a unitary part.
