Abstract: Disclosed is a mussel adhesive protein including at least one photocaged 3,4-dihydroxyphenylalanine derivative residue including a protecting group on at least one hydroxyl residue of its catechol moiety. The photocaged 3,4-dihydroxyphenylalanine derivative residue replaces a naturally occurring amino acid and the protecting group can be cleaved from the 3,4-dihydroxyphenylalanine derivative residue by irradiation with UV light.

Abstract: A method for producing a containing system for a liquid dispenser having a dimensionally stable outer container and a collapsible inner container, in the form of a pouch, arranged within the outer container. The method includes starting from the outer container, at least one layer of a pouch material being applied to an inner wall of the outer container. For this purpose, the pouch material is applied in the form of a liquid or powder to the inner wall, where, after solidifying or fusing, it forms a ply of a wall, of the inner container. The ply detaches from the inner wall of the outer container when the inner container collapses.

Abstract: A fluid dispenser having an accumulator and a discharge head. The discharge head is secured to a base unit of the dispenser, which base unit includes a fluid accumulator. The discharge head has a housing displaceable relative to the base unit for actuating the dispenser. The discharge head has an inlet through which fluid travels from the fluid accumulator into the discharge head, and a discharge opening through which the fluid is delivered into the atmosphere. A swirling chamber having an inlet channel is provided between the fluid inlet and the discharge opening so that inflowing fluid is provided with a swirl which forms a spray stream when exiting the discharge opening. The swirling chamber is switched between a first and a second configuration by changing the geometry of its walls and/or the inlet channel.

Abstract: A discharge head for a liquid dispenser having a coupling device fastening to an outlet connector of a liquid store, a liquid inlet, and a discharge opening. The discharge head has a pump device conveying liquid from the liquid inlet to the discharge opening, and a ventilation channel. The discharge head has an end surface by which the liquid store is substantially closed off at the distal end of the outlet connector and which is extended through by the liquid inlet. The end surface and the coupling device are formed as part of a common main component. The end surface has a ventilation aperture which is part of the ventilation channel and through which air flows into the liquid store in an inflow direction. The ventilation aperture has a minimum clear cross section of at most 3·10?2 mm2.

Abstract: A discharge head for a liquid dispenser having a base, an actuation handle, a liquid inlet and a discharge opening. The discharge head has a pump mechanism which conveys liquid from a liquid store to the discharge opening. To control liquid to be discharged and/or inflowing air, the discharge head has a valve with a valve flap which closes a valve channel and transfers to an open position by a positive pressure that exceeds a threshold positive pressure. The discharge head has an effector element bearing on the handle and the base, which deforms when the handle is pressed down. The valve flap is designed and attached to the effector element such that the deformation of same acts on the valve flap so that the threshold positive pressure, beyond which the valve flap leaves its closed position, is at least 10% lower in an actuated end position than in a non-actuated end position.

Abstract: A discharge head having a housing, a coupling device for attachment to a liquid store, a discharge opening and an outlet channel extending from an inlet region up to the discharge opening and by which the discharge opening is supplied with liquid. For throttling the liquid to be discharged, the discharge head has a throttle device with a throttle channel for reduction in the liquid pressure and/or the liquid flow through the throttle device. The throttle device is switchable between throttling and release states, and a minimum free cross section of the throttle channel is varied to subject liquid flowing in the direction of the discharge opening to a high throttling effect in the throttling state and liquid flowing in the direction of the inlet region is subjected to a low throttling effect in the release state.

Abstract: Discharge head for a liquid dispenser including a housing, a coupling device for attachment to a liquid store, a discharge opening through which liquid is dispensed and an outlet channel extending from an inlet region, pointing in the direction of the liquid store, up to the discharge opening and via which the discharge opening is supplied with liquid. A throttle device is arranged in the outlet channel and includes a throttle channel for reducing liquid pressure and/or liquid flow through the throttle device. The throttle device is designed in the form of a dynamic throttle device, in which a free cross section of the throttle channel is reduced in size with increasing pressure prevailing at the throttle device, or with greater liquid flow flowing through the throttle device.
