Definitions

  • the present invention relates to a top-up container assembly comprising a dispensing cap with a valve, and dishwashing cleaning products comprising the top-up container assembly.
  • Plastic bottles comprising a spout for dispensing a liquid or a viscous composition are well known in the art, especially in the field of dishwashing cleaning products. These bottles are typically so-called “top-up" bottles.
  • a user In order to dispense the composition, a user typically needs to open a cap to expose the spout, then invert and squeeze the bottle to dispense the composition.
  • One problem with spouts is that, because of the spout's opening, the product flows out upon inversion of the bottle, even when the bottle is not squeezed.
  • Another problem is that it is difficult to control the amount of product to be dispensed from the bottle.
  • Another problem is mess. Bottles with spouts tend to leave product around the rim of the spout. As a result, the bottle does not only looks messy, but the product also dries and forms a crust. If the crust is allowed to build up, then it eventually blocks the spout. All these problems lead to consumer dissati
  • valves e.g. slit valves
  • top-down containers or tubes which hold a liquid or viscous composition.
  • Top-down containers or tubes are products which rest on their dispensing cap, when they are stored on a horizontal surface.
  • KetchupTM products are products which rest on their dispensing cap, when they are stored on a horizontal surface.
