Pressurized pack for viscous materials
First Claim
1. A dispenser for dispensing a product, said dispenser consisting of:
- a vessel with a vessel axis;
a valve having a range of positions from closed to open;
a nozzle connected by a connecting means to the valve;
an attachment;
a lever with a grip region for a user;
an actuator with a supporting region comprising a ramp extending helically around a portion of the valve, and a variable engagement point for the lever;
wherein the engagement point is provided along the ramp on the actuator;
wherein said actuator can be rotated relative to the lever, to the attachment and to the nozzle about the vessel axis, thereby displacing the engagement point axially along the vessel axis, causing the lever to pivot away from the vessel axis about a lever axis that is fixed with respect to the attachment;
and wherein pivotal movement of the lever around the lever axis towards the vessel axis displaces the supporting region axially with respect to the vessel axis, thereby selectively opening the valve.

Abstract
The invention relates to a dispenser for dispensing an adhesive or sealant from a vessel, in particular from a pressurized vessel, via a valve. For this purpose, the dispenser is equipped with a lever with a grip region for actuating the valve. The dispenser also has an attachment, on which the lever is fitted in a pivotable manner, and an actuator with a supporting region for the lever. The actuator is configured such that it can be rotated relative to the attachment, and the supporting region is therefore variable, in order to change the effective lever path for the actuation of the valve, for activating or deactivating the dispenser or for varying the volume flow as product is dispensed.

17. A dispenser for dispensing a product from a pressurized vessel having a vessel axis and a valve having a range of positions from closed to open, comprising:
-
a nozzle connectable to the valve, an attachment to hold the dispenser to the vessel; an actuator having a first surface positionable in contact with the valve and an opposing, axially spaced second surface defining a ramp extending helically around a portion of the valve;
the actuator user rotatable around the vessel axis without rotation of the attachment or the nozzle;a lever fixed to the attachment for pivotal movement about a lever axis, the lever including a grip region extending from the lever and an engagement point between the lever axis and the grip region; wherein the actuator ramp is disposed between the valve and the lever engagement point and movement of the grip region toward the vessel axis pivots the lever engagement point into contact with the actuator ramp second surface thereby moving the actuator first surface into contact with the valve to displace the valve along the vessel axis from the closed position. - View Dependent Claims (18)
