ABSTRACT:
A utensil for dispensing liquid, such as detergent, from a bag set in the utensil which contains the liquid, and bags for use with the utensil. The bag is comprised of a synthetic resin film and is housed in a container body having an opening at its top end. The top end opening of the container body is closed by a cover member to which is attached a liquid delivery element, such as a pump with a nozzle. A suction tube projects downward from the liquid delivery element. The tube is adapted to sealingly pierce the upper surface of the bag set in the container body for communication with the interior of the bag. That portion of the bag which is pierced by the suction tube is formed of a nylon film, or an unstretched nylon film in particular. Therefore, the tube is not liable to be torn when pierced by the tube, and a hole formed by the piercing comes in close contact with the tube.
