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.
