Abstract
A container comprising a sidewall and an endwall connected by a heat sealed joint. The endwall has, in an operable orientation, a major upper surface, an endless, upwardly opening, peripheral channel and a heat sealable, fluid barrier, surface layer adhered to the major upper surface of the endwall. The sidewall has a heat sealable, fluid barrier, surface layer adhered to its inner and outer surfaces. The end of the sidewall is engaged and crimped within the endwall channel with the surface layers of the sidewall heat sealed to the surface layer of the endwall to form a sealed, mechanically rigid joint.
Claims16
A container comprising:
- a) an endwall having, in an operable orientation, a major upper surface, an endless, upwardly opening, peripheral channel and a heat sealable, fluid barrier, surface layer adhered to the major upper surface of the endwall;
- and
- b) a sidewall, having an inner surface, an outer surface, a heat sealable, fluid barrier, surface layer adhered to at least one of said sidewall surfaces, an end of the sidewall being engaged within the channel with the surface layer of the sidewall heat sealed to the surface layer of the endwall.
A method for forming a container, the method comprising:
- a) forming an endless, peripheral channel in an endwall constructed of a sheet material having, in an operable orientation, a major upper surface and a heat sealable, fluid barrier, surface layer adhered to the major upper surface and extending into the channel;
- b) inserting a sidewall into engagement in the channel, the sidewall having an inner surface, an outer surface, and a heat sealable, fluid barrier, surface layer adhered to at least one of said surfaces;
- c) crimping the endwall channel against the sidewall to form a joint;
- and
- d) heating said joint to heat seal the heat sealable layers of the endwall and the sidewall at the joint.
