20150238989 | DISPENSING PUMP - A dispensing pump includes a housing extending along a longitudinal axis and configured to be inserted in a bottle. The housing defines a dosing chamber and includes a venting hole. A retaining ring is fastened to the housing and inserted therein. A hollow stem is associated to a piston and inserted in a hole of the retaining ring leaving a passage. The hollow stem and piston are movable between a lowered position and a raised position corresponding to different volumes of the dosing chamber. A venting path includes at least the passage between the hollow stem and the retaining ring and the venting hole. Through the venting path a volume of air enters the bottle through the venting hole during the pump actuation to replace liquid pumped out from the bottle by the pump. A venting valve is interposed between the hollow stem and retaining ring, along the venting path. | 08-27-2015 |
20150090738 | ACTUATING DEVICE FOR A DISPENSING PUMP OF A DISPENSER - An actuating device for a dispensing pump of a dispenser is configured to be used on a container, in an upward position of the container. The actuating device includes a pouring cup and a connecting device. The pouring cup defines an inner chamber for receiving a metered amount of a product. The connecting device includes a hollow structure extending along a longitudinal axis between at least a first end and an opposite second end. The structure is connected and supports the pouring cup. The structure defines a channel extending along the axis between an input opening and an output opening. The output opening emerges into the inner chamber whereby the channel communicates with the inner chamber. The second end includes a connecting portion configured to be connected to a hollow stem of the dispensing pump whereby the channel communicates with a dispensing cavity defined by the stem. | 04-02-2015 |
20140166700 | DISPENSER - A dispenser includes a hollow containment body which is at least partly insertable into a bottle, the body having a hole located inside the bottle and an orifice for pumping a liquid product contained inside the bottle; a ring nut able to be engaged on a neck of the bottle and externally associated with the body; a piston slidable inside the body between a raised position and a lowered position; a hollow stem slidable inside the body and associated with a dispensing spout to actuate the piston in order to dispense fluid contained in the bottle; and at least one aperture formed in the body to selectively place an ambient air inlet passage in fluid communication with the hole in the body; the ring nut having a first substantially cylindrical portion and a second substantially cylindrical portion which are mutually coupled to define the air inlet passage between them. | 06-19-2014 |
