Closures offering Valve-Function for squeezable Products

Tuesday 30. November 2010 - BERICAP, globally a leading company producing plastic closures for food and beverage as well as for the chemical industry introduced a hinge closure with a valve function for ketchup and mayonnaise.

Closures offering a valve-function are already in the market since several years being used for ketchup and mayonnaise in the food industry. The valve opens, when the consumer is pressing the bottle and a well dosed squeezable product can exit. If the pressure is released the valve does close and the area of the opening remains clean. Dirty opening of a closure used for viscose products are belonging to the past.
But the is still a problem: However, the today’s used closures are equipped with a silicon valve, which creates higher costs, but more important it pollutes the recycled material, which in itself is a problem as you have two different materials in your recycle process.
BERICAP has designed a cost-saving valve, which either is a one-piece closure or alternatively a second piece can be inserted into the closure. As the second part is made of the same plastic material as the closure, there are no problems in the recycling process. The two piece solution of BERICAP is successfully introduced in the Turkish market recently.
The closure with valve function is designed primarily for ketchup and mayonnaise and offers a cost efficient and finally environmental friendly solution. The valve function can be carried over to other closure sizes.
