Abstract: To further improve a dispenser of the type in question, in particular with regard to an advantageous production, it is proposed for the support on the inner surface of the cap part to be formed by means of a support section of the support part, which protrudes below the sealing zone and which simultaneously forms an accommodation for the upper free edge of the bellows part in a one-part embodiment with an accommodating section. Provision can thus be made for a one-part embodiment of the support part.

Abstract: The invention relates to a dispenser (1) for dispensing liquid to pasty substances (4), comprising a pump head (2), a cap part (32), which has a dispensing opening (34), and a pump chamber (12), which is embodied in the pump head (2), has a pump chamber wall and has an outlet valve (24), further comprising a support part (25), which accommodates the outlet valve (24), wherein the support part (25) sits in the cap part (32) and is supported on an inner surface of the cap part (32), wherein the pump chamber (12) is further formed by a bellows part (13), the upper free edge of which is arranged so as to be assigned to the support part (25), and wherein the outlet valve (24) rests against the support part (25) in a sealing zone.

Abstract: The invention relates to a dispenser (1) for fluid to paste-like matters (M), having a pump chamber (20) comprising at least one outlet valve (28), a storage chamber (2), and a flow path (2) connecting the storage chamber (2) to the outlet valve (28), wherein a transport safeguard device is provided in order to avoid a discharge of the matter during transport. In order to advantageously configure a dispenser of the type in question with respect to the transport safeguard device, the invention provides that the flow path (W) to the transit safeguard device can be locked.

Abstract: A dispenser for fluid to pasty masses has a pump chamber that has an outlet valve. The pump chamber consists of an upper pump chamber part and a lower pump chamber part, which can be moved, relative to one another, for a pumping process. In order to prevent unintentional exit of mass under certain stresses such as severe vibrations, the outlet valve is moved into a release position before the beginning of a pumping process, by means of a control part.

Abstract: The invention relates to a dispenser for delivering portions of liquid to pasty substances, having a storage container and a pumping chamber, the pumping chamber having at least one valve, and having a delivery head which can be displaced relative to the storage container and the displacement of which allows the substance to be delivered, the delivery head further having formed in it a delivery channel with a delivery opening, which delivery opening can be closed by a closure part which is removable, but is held in captive fashion on the delivery head. In order to specify such a dispenser for delivering portions of liquid to pasty substances which is configured in an advantageous manner, in particular, in respect of a closure part, it is proposed that the closure part is a sliding part which also forms a delivery-channel portion and interacts with a fixed closure pin.

Abstract: The invention relates to a hand-operated dispenser (1) for highly viscous to fluid substances with a pumping chamber (17) and with at least one outlet valve (12) and a storage chamber with a feeding piston (5), wherein the dispenser (1) is designed for the output of two different substances, a first substance (4) and a second substance (22). The second substance (22) is brought out by the pressure of the first substance (4). To develop a dispenser of this type for most efficient use, it is proposed that a movable separating body (T) be arranged between the first substance (4) and the second substance (22).

Abstract: A metering pump made of plastic for the metered dispensing of liquid and/or pasty media from a bottle-like container, can-like container or tube-like container with a follower piston. A pump chamber delivering the medium is connected via a suction valve with the container and has as the pumping member an elastic bellows that forms the pump chamber and is arranged between a dimensionally stable lower housing part and a likewise dimensionally stable upper housing part that is telescopically movable in relation thereto. The upper housing part has the discharge opening, which is connected via a discharge channel and a discharge valve with the pump chamber. The bellows has an upper ring collar sealingly surrounding a ring wall of the upper housing part. The ring wall is provided with a displacement piston that has a smaller diameter and protrudes into the bellows.

Abstract: An automatic closure for elastically deformable, tube-like or bottle-like containers of pasty or liquid media has a dispensing opening (5), which is arranged in a front wall (3) of a hood cover and can be closed by an axially movable closing member (8). The closing member (8) is part of an elastic membrane wall (9) of an elastic, hood-like hollow body (10). This hollow body surrounds a ring wall (12) of a chamber (15), which is closed by a bottom (13), through which the medium flows and is provided with a ventilating channel. To make possible a sufficient suction ventilation of the container in a simple manner, the inner ring wall is surrounded by a second ring wall, which forms an annular groove (17) with the inner ring wall (12). The annular groove (17) has at least one axial ventilating opening (30, 31), which connects the ventilating channel (28,29) to the hollow space (27) surrounded by the second ring wall (16).

Abstract: A metering pump dispenser for simultaneous metered dispensing of liquid and/or pasty media has at least two separate storage chambers (1, 2), which are arranged in a common pump housing (9) and with which separate metering pumps with a priming valve and a dispensing valve each are associated. The metering pumps can be actuated by a common actuating member, which is mounted axially movably in the head part of the pump container and has one or more dispensing channels.
