Bright Ideas: Our 4-Corner Locking System

Searching for the perfect to-go food container to meet your restaurant or other food business needs is a constant challenge. Restaurant owners and product suppliers have long searched for that just-right combination that keeps food hot, preserves flavor and appearance, does not spill or leak and does not cost a fortune. Too often containers are flimsy, poorly designed or simply do not work for the food they are holding. It is no small task to overcome a negative review or poor customer experience because of a failed food container.  

Sunshine Supply Company has been an innovative presence in the container industry for over 20 years. Sunshine is committed to innovation in order to create products that patrons love and are easy for restaurant workers to use. The company has been working to drive the industry forward since our start in 1997, beginning as a small local janitorial supply company for restaurants. Today, we are a large-scale manufacturer, and our company only continues to grow and gain recognition for our recognizable, patented designs. 

Patented 4-Corner Locking System

Innovations and improvements to food container designs only come around every so often. Sunshine Supply has proudly contributed to the industry by creating a patented 4-corner locking system, which keeps food containers closed and its contents secure. This innovative design seals in freshness, prevents spilling and keeps food hot. Whether it is keeping leftovers fresh or presenting beautifully crafted meals on the go, restaurants can count on the 4-corner locking system to keep food looking great and full of flavor.  

Our patented 4-corner locking system: 

  • Is designed with both the consumer and restaurant needs in mind.  
  • Has a separate point of locking on each corner of the container, keeping the lid on securely.  
  • Is simple and convenient to use, while easy to remove.  
  • Keeps food hot, intact and prevents spills or leaks.  
  • Keeps food fresh, preserving taste and appearance. 
  • Is available in a variety of products, including single and multiple compartment containers and large capacity containers.  

Keeping food from leaking out of to-go containers is one of the biggest challenges the industry faces. So, Sunshine continues to innovate and push the envelope to develop products that are reliable, convenient to use and meet the individual unique needs of the remarkably diverse restaurant and food service landscape.  

Sunshine Supply Company uses high-quality Polypropylene (PP) in most containers and lids, and all plastic materials are BPA-free. PP has less of a likelihood to leak chemicals into food and is lightweight, sturdy, resistant to high heat and microwave safe.  

Over the last 18 months, the restaurant industry had to work hard to persevere. This has caused a major shift in the restaurant industry to focus more on delivery and pick-up orders rather than customers dining in. The focus on effective, high-quality, and affordable to-go food containers became more intense than ever before. Sunshine Supply Company has been at the forefront, providing restaurants and distributors with reliable products and impeccable service.
