A device for dispensing a fluid substance (F) comprising a manually operated pump (2) coupled to a deformable bag (3), the deformable bag being housed inside a container (4); the container is formed of a collar (5) made of plastic coupled to a tubular element (6) formed from a paper- or cardboard-based material, the tubular element featuring a bottom (7), the collar (5) featuring ribs (N) made on a surface thereof which comes into contact with an internal wall of the tubular element (6).

A refill device for a container having an opening to a cavity including a first connection element with first connection means for removably connecting the refill device to the opening, a bag first part filled with a substance for housing in the container, a neck and a connection part between the neck and the first part, and a flange, a pump, a ring nut element connected to the first connection element to connect the pump and bag thereto, the first connection element including a body with an upper part including an upper opening delimited by a wall for resting a portion of the flange and connection means, a lower part including an opening and first means for removably connecting the refill device, the first connection element including second connection means for removably connecting a protection element to the first connection element before associating the refill device with the container.

The device for packaging and dispensing a product includes a preassembled inner unit mounted in a hollow body, with a dispensing head surrounded by an upper connector which allows removably attaching the body. The inner unit includes a reservoir, and the head sealingly closes the opening of the reservoir. A peripheral retaining ring for the inner unit keeps the reservoir and head integrally secured. The connector is connected to the body by a locking action which is achieved by relative pivoting between the connector and the body, without interference with the ring. An actuating portion of a dose metering pump of the head is accessible on the top via a channel of the connector, while a tubular outer portion of the connector covers the area of attachment to the body, by axially extending an outer wall of the body.

A dispenser for dispensing liquid or pasty materials has a head part with a dispenser opening. The dispenser opening is formed by lip sections which lie directly on top of each other. A lip section for opening the dispenser opening can be lifted from the other lip section by means of a lifting part that engages on the lip section. The lifting part acts on the lip section with a loading direction that runs transversely to a dispensing direction of the material.

The invention relates to a dispenser container consisting of an outer container and an inner container for receiving a fluid, wherein the outer container and the inner container are formed from blow-moulded plastics, which do not form an integral connection with one another, and wherein a first plastic from which the inner container is formed has a higher elasticity than a second plastic from which the outer container is formed, such that the inner container is deformable, and wherein the outer container has at least one pressure compensation opening for pressure compensation in the region between the outer container and the inner container, wherein the inner container has a first outlet region and the outer container has a second outlet region, wherein the first outlet region can be shifted relative to the second outlet region in an outlet direction.

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.

A fluid dispenser includes a ring nut to be screwed on a bottle neck and including a shoulder and a collar extending in elevation from the shoulder. It also includes a dispensing head including a central portion, a spout designed to dispense the fluid contained in the bottle and a protective skirt extending to contain the collar of the ring nut. The protective skirt extends close to a peripheral portion of the shoulder and, in a closed configuration of the dispenser, has a safety distance from the shoulder. The dispensing head includes a cylindrical crown shaped to form a toothed profile and located between the protective skirt and the central portion. The ring nut collar includes gripping elements with a longitudinal extension and the toothed profile engages the gripping elements when closed. The toothed profile and the gripping elements are shaped to allow reciprocal rotation of the dispensing head.

A set including a pump dispenser for discharging pharmaceutical or cosmetic liquids and an external evaluation unit, which is designed to be exchangeable so that, after the pump dispenser has been emptied, the evaluation unit can be attached to a new pump dispenser. The evaluation unit can be attached to the discharging head of the pump dispenser such that the evaluation unit detects an actuation button and can be partially displaced with same. The evaluation unit can alternatively have a receiving container which is open on at least one side and into which the pump dispenser can be inserted and the force application of which is detected on actuation.

[Object] To provide a pump dispenser that makes it possible to prevent air from entering a conduit even in a case where there is little liquid left in a vessel and prevent back-flow drippage of the liquid from the conduit even in a case where the pump dispenser has been removed from the vessel.

[Solution] An adaptor A that is attached to a pump dispenser B configured to suck up liquid out of a vessel via a conduit 3 and eject the liquid from a nozzle includes a tubular portion 1 that is attachable to the conduit 3 and that has an opening in an upper part thereof and a bottom wall portion 11 forming the bottom of the tubular portion 1. The bottom wall portion 11 includes an outlet hole 2, and the diameter ER of the outlet hole is smaller than the inner diameter TR of the conduit.

A pump assembly which provides a frangible air vent mechanism for providing communication between the atmosphere and the interior of a bottle to which the pump assembly is to be coupled. A vent port is provided through a bottle cap member having an inner end open into the bottle and an outer end open to the atmosphere. A frangible plug member is received in the vent port with the frangible plug member when unbroken preventing flow through the vent port and the plug member when broken permitting flow through the vent port. A vent tab member is coupled to the frangible member with the vent tab member extending from the frangible member accessible on the exterior of the bottle cap member for engagement to apply forces to the vent tab that are translated to the frangible vent member to break the frangible member.
