Patent number: 9233384Abstract: A dispenser for discharging liquids with a liquid reservoir for accommodating the liquid prior to being discharged, and a liquid outlet passage which leads to a liquid outlet opening through which the liquid reservoir communicates with a surrounding atmosphere. In a use position, the liquid outlet opening is arranged below the liquid reservoir such that the liquid flows on account of the weight thereof in the direction of the liquid outlet opening, and the liquid outlet passage in the use position does not simultaneously permit air to enter the liquid reservoir and liquid to exit into the surrounding atmosphere. In order to reduce the internal volume of the dispenser and therefore to effect a discharge of liquid, a slide is pushed manually in an actuating direction from a stroke starting position into a stroke end position.Type: GrantFiled: February 22, 2012Date of Patent: January 12, 2016Assignee: APTAR RADOLFZELL GMBHInventors: Juergen Greiner-Perth, Matthias Wochele, Judith Auerbach
