Induction Sealing Caps with Brushes
Traditionally, an induction heat seal liner is used to close a container. However, for some, it also acts as the delivery mechanism when using the product.
This is often the case with products featuring a brush-style cap, including Dr Beckmann’s Carpet Stain Remover. Mounted on top of the screw on cap is a sponge/brush applicator which delivers the cleaning fluid direct to the stain without removing the cap. For this design to work without over-wetting the carpet this clever packaging design relies on induction cap sealing with an Enercon induction sealing machine.
As with the conical cap, the distance from the top of the cap to the induction foil seal, can be a challenge for many induction cap sealers. However, once more, Enercon Industries’ deep tunnel coil has been specifically designed to tackle such challenges.
The difficulty with this container doesn’t stop there though. Typically, the consumer removes the foil seal prior to using a product. However, in this instance, the consumer is told to remove the cap, pierce the induction foil seal with a pin, leaving it in place and then to replace the sponge/brush applicator. To use on a stain the bottle is inverted and squeezed until the sponge is wetted with the cleaning solution. Then the bottle is pushed and pulled against the carpet in the cleaning action. And this happens time and time again throughout the lifetime of the product in the home.
Paul Bennion, European Sales Director for Enercon Industries, explains:
“This action puts tremendous pressure on the induction seal, not only is there pressure from squeezing, but the bottle is flexed as the cleaner is used. The quality of the foil seal is essential to the correct usage of the product. Dr Beckmann’s require 100% consistency of seal to ensure their customers’ satisfaction.”
