Claims21
A container and handle, comprising:
- a blow-molded plastic container body having a sidewall;
- and
- a separately formed one-piece plastic handle permanently welded to said sidewall, said handle having at least one raised portion which is melted by ultrasonic energy and which, upon hardening, creates a permanent weld to said sidewall.
A container and handle combination, comprising:
- a blow-molded plastic container body having a base and a finish connected by a sidewall;
- and
- a separately-formed one-piece plastic handle having a rear portion engaging said sidewall a spaced distance from said finish and said base, said rear portion having at least one raised portion extending therefrom which is melted by ultrasonic energy and which, upon hardening, creates a permanent weld to said sidewall.
A container having a separate handle welded thereto, comprising:
- a blow-molded container body having a sidewall;
- a separately formed handle having a grip portion spaced from said sidewall and a securement portion engaged with said sidewall;
- and
- at least a pair of integrally raised protrusions on said securement portion which are melted by ultrasonic energy and which, upon hardening, create a permanent weld to said sidewall at spaced locations relative to said grip portion.
