1961

1961 Push/Pull

In 1961 Stull Technologies co-patented one of the first Push/Pull closures with one of the world's leading drug company. The Push/Pull cap evolved over time and is now a standard on many household products.

1964

1964 Twist Open/Close

In 1964 Stull Technologies patented one of the first Twist Open/Close caps which revolutionized product dispensing. Its consumer friendly design and revolutionary dispensing style quickly spread, helping to create brand recognition for producers of glue and yellow mustard. The Twist Open/Close cap continued its success with other products in health and beauty aide, household chemicals, pharmaceuticals, and other specialty markets.

1968

1968 Vinegar Trap

In 1968 Stull Technologies developed a method of separating unwanted vinegar from mustard. The first vinegar trap was developed and patented by Stull which was quickly incorporated into closures sold to the leading producer of yellow mustard. To date no other method has been successful.

1975

1975 Eye Care Products

Stull Technologies has supplied numerous pharmaceutical companies with a hinged dispensing cap for eye care products for over twenty years. The closure has evolved over time to the current design, but has remained the cap of choice for the #1 producer of contact lens cleaners and other eye care products.

1979

1979 Products Requiring Child-Resistant Features

In 1971 Stull developed its first child-resistant closure for cans. The fitment was designed for use with charcoal lighter fluid and other products requiring child-resistant features. In 1979 Stull continued to use its knowledge of child-resistant packaging, working to design the first child-resistant hinge cap for plastic bottles. The design has remained a standard for over twenty years for all major packagers of charcoal lighter fluid.

1982

1982 The liquid trap

In 1982 Stull Technologies developed the first hinged cap for ketchup which also incorporated a water barrier and liquid trap. The liquid trap was the first of its kind used for ketchup. It collected the liquid that gathered on the surface of the product while stored in the refrigerator. Stull sold this design to two of the top three producers of Ketchup for over twenty years.

The StullCONTROL™ Valve Technology

The StullCONTROL™ Valve Technology

Another development from Stull Technologies is the StullCONTROL™ Valve Technology. Stull uses a soft injection molded dispensing valve to offer consumers complete dispensing control. Stull's Valve Technology can be adapted to a number of closures and used for a variety of applications to eliminate the spills and mess while providing pin point dispensing accuracy. The valve is pressure activated, dispensing as the consumer squeezes the bottle, but as it automatically returns to its original position the valve quickly shuts off the flow of product maintaining a clean presentation after repeated use. The valve can be used with both wet and dry products, and by using modern co-injection technologies the piece price is affordable.

The StullSURE™ Child Resistant Closure

The StullSURE™ CR Closure

Stull will launch a 28mm 415 and a 24mm 410 with the ability to add a perforated tamper evident label. The label will be applied following the closing process at Stull. Pulling a tab located on the front of the label will tear away the center portion leaving a ring around the locking peg, indicating the product has been previously opened. Following the flat top version, Stull will launch the next generation StullSURE™ CR Closure with a domed cover, as well as a version for cans. The StullSURE™ CR Closure will immediately become the most appealing one-piece child-resistant closure available today.
