Abstract (en)
[origin: US5240149A] The invention relates to a closure cap (5) having a dispensing opening (6) for containers with flexible walls, which can be pressed together by hand for the dispensing of spray product which is in connection with the dispensing opening (6) by means of a dip tube (7). Upstream of the dispensing opening (6) is an outlet valve (8), which is open when there is positive pressure in the container, whereas an air-admitting opening (9) is assigned an air-admitting valve (10), which is open when there is negative pressure in the container. By virtue of the outlet valve (8) upstream of the dispensing opening (6), the readmission of air to the container and consequently the risk of sucking in through the dispensing opening (6) substances contaminating the container content is prevented. Maintaining the quality of the spray product in the container is ensured by virtue of the air-admitting opening (9), separate from the dispensing opening (6), and the air-admitting valve (10), which opens only when there is negative pressure in the container.
