Dispenser for the optionally atomized discharge of an in particular liquid medium from a container
First Claim
1. Dispenser for discharging medium from a container for discharge operation in at least two partial strokes performed in an operating direction, thereby discharging with each of the two partial strokes a partial charge of the medium, comprising:
- a discharge opening for the medium connected to the pump by a discharge channel, an operating member for manually operating the pump by exerting a manual operation force, guiding means for the operating member, at least one path (22b) for the guiding means including first and second partial stroke paths, the first partial stroke path allowing operation of a first one of said two partial strokes, the guiding means being guided along said first partial stroke path and interrupting the operation at a first partial stroke end position occupied by the operating member after said first one of said two partial strokes, changeover means for automatically transferring said guiding means to said second partial stroke path allowing operation of the second one of said two partial strokes, the changeover means including at least one spring, said spring being loaded during said first partial stroke, at least one blocking means (27) being provided in each partial stroke path for preventing partial strokes of the operating member (14), before a predetermined level of said operating force is applied to the operating member (14) for performing one of said two partial strokes.

Abstract
A method of producing a flexible conduit whose dimensions and shape can easily be changed according to its use is described. The method includes producing elongate elements from an elastic flexible material, wherein the cross-section of the elongate elements each have at least one corrugation and extend so as to be rectilinear longitudinally. Each elongate element is fixed to at least one elongate holding element made of rigid pliable material so as to keep its shape after bending. Several sets of elongate elements are produced and are connected to each other along their adjacent longitudinal edges in order to form a flat enclosure whose dimensions correspond to those of the deployed flexible conduit. The flat enclosure is then deformed so as to close it and to obtain the required shape of the cross-section of the conduit, wherein the enclosure is kept in shape by the deformation of the elongate holding elements. Then, the adjacent ends of the shaped enclosure are connected.

20. Dispenser for discharging medium from a container for discharge operation in at least two partial strokes performed in an operating direction thereby discharging with each of the two partial strokes a partial charge of the medium, comprising:
-
a discharge nozzle for the medium connected to the pump by a discharge channel, an operating member for manually operating the pump by exerting a manual operation force thereon, the operating member (14) being moveable into a casing (12) and having an operating surface (16) for a finger of the user, a finger support (15) at the casing (12) for operating the dispenser, a sleeve (13) having a guide slit (22b), in which a first sliding member (21b) is guided, and a changeover slit (22a), in a second sliding member (21, 21a, 21b) is guided, the guide slit having generally a Z-shape and having at least first and a second substantially linear slit sections parallel to the operating direction, and in each of said linear slit sections a blocking projection (27) is projecting from a wall of the slit (22b), each blocking projection preventing start of a partial stroke unless a predetermined level of the operating force is applied to the operating member, the first sliding member sliding, during the first one of the two partial strokes, in the first slit section, the guide slit having an intermediate section between both of the linear slit sections defining a rest shoulder for the first sliding member (21b) in a first partial stroke end position (25) for interrupting -the operation after the first one of the two partial strokes, the changeover slit (22a) containing a blade-like spring (23) being tensioned by the second sliding member (21a) during the first one of the two partial strokes, both paths and the sliding members being so arranged that after the first one of the two partial strokes the spring (23), acting on the second sliding member (21a), moves the first sliding member (21b) in the intermediate section into the second slit section in which it is in a start position (30b) for a second one of the two partial strokes.
