Thermally Insulated VIP Sandwich Shipper and Method of Making Same

摘要

A thermally insulated VIP sandwich shipper for a temperature sensitive payload is provided. The shipper comprises an outer shell, an inner shell and vacuum insulated panels sandwiched therebetween. The outer shell and the inner shell may be unitary rigid structures made of an expanded foam material and comprising a bottom having a perimeter and sides extending from the bottom perimeter and terminating in a rim. The inner shell rim may be spaced from the outer shell rim to define a gap, the gap being sealed to create an enclosed space within which the vacuum insulated panels are located. Each vacuum insulated panel may be oriented substantially orthogonally to at least one adjacent vacuum insulated panel and have an edge that abuts the adjacent vacuum insulated panels.

1. A packaging system for shipping a temperature sensitive payload, the packaging system comprising:
a unitary rigid outer shell made of an expanded foam material and comprising a bottom having a perimeter and sides extending from the bottom perimeter and terminating in a rim, the outer shell having an R value; a unitary rigid inner shell made of an expanded foam material and comprising a bottom having a perimeter and sides extending from the bottom perimeter and terminating in an inner shell rim, the inner shell rim spaced from the outer shell rim to define a gap, the gap being sealed to create an enclosed space, the inner shell having an R value; and thermal insulation panels located in the enclosed space between the outer shell and the inner shell, each thermal insulation panel having an edge that abuts an adjacent thermal insulation insulated panel, the thermal insulation panels having an R value greater than the R values of the outer shell or the inner shell.
