The Cambro Story

Started in a garage in the 1956

Cambro started with a new product, the fiberglass tray

Cambro started with the military in the late 50’s

Cambro had a yearly contract with GSA and sold 50,000 trays per year.

Cambro then sold pan carriers and beverage carriers which we still do today.

UPCS180

This item has been the standard item for 10 years!

There became a need to improve the container for functional reason.

A new design was developed between NATICK, CORANET, CAMBRO, and the design firm TIAX.

Criteria:

-Reduce storage area by 25%

-Reduce the weight by 10%

-Maintain the military specs for Hot and Cold food holding times and temperatures

-Hold 5 Tray Packs

-Hold 3 6” deep metal food pans

-No cost increase

New Design

Develop an insulated hot food container with reduced volume and weight while still maintaining the desired characteristics.

Thermal performance: a full container maintains food temperature, starting from 180oF, above 140oF for at least 4 hours in a -20oF ambient temperature

The in-use cube volume will be significantly less than the 4400 in3 of the current IFC but hold one more tray pack and still hold three 1/3 size GN pans

Insulated Hot Food Container Program Project Overview Goals

Based on Phase I reviews with Natick, we have pursued the development of field-able prototypes of the ‘lid and container’ design.

“One-Piece” Designs – 4” & 6” deep Primarily for polymeric tray packs

Insulated Hot Food Container Program Project Overview Lid and Container Design

During Phase II, the Natick team redirected to further develop the “one-piece” conceptual prototype and to develop concepts for a heatable, insulated beverage container.

Lids nest together separate from their containers.

Additional foam for more margin on tray pack hold time and small increases in dimensions have reduced volume savings to 19.5%.

Notes: 1. Holding time test conducted with 36 lbs of water for 6" deep pans, and 31.25 lbs of water for 5 tray packs 2. No design meets all MANPRINT guides (44 lbs total weight, 22" Length by 10" Width). All are over the MANPRINT dimensions. With steam table pans, all are too heavy. With tray packs, only one is too heavy 3. Weight will largely depend on minimum wall thickness possible in production. Empty weight includes weight of 4 Cambro latches

CONTINUES TO WORK ONYOUR NEEDS!

Cambro has learned a great deal from this development project and will make changes to our

current product to meet some of the objectives defined in the project.

STAY TUNED!!!
