  • Patent number: 7475436
    Abstract: The invention relates to a dispenser stick (1) for storing and applying a pasty gradually removable stick compound from a cosmetic or otherwise product, such as for example a deodorant stick or glue stick. Said dispenser stick is provided with a cylindrical housing (1?) comprising an upper dispensing opening, a closure cap (2) that hermetically seals the dispensing opening via a sealing lip (5), and a feeding plunger (7) that can be axially displaced inside the housing (1?). The dispenser stick (1) is characterized in that the feeding plunger (9) can only be displaced towards the dispensing opening and is blocked in the opposite direction and in that the closure cap (2) is configured as a double-walled structure that has an interior cap (3) that can be axially displaced relative to the closure cap (2).

  • Patent number: 7464839
    Abstract: One disadvantage during delivery of products such as foams, for instance shaving foam or gel, self-foaming products and other products that are applied with a pressurized system from a conventional, pressurized dispenser container with the aid of known dispenser heads that can be inserted into the delivery valve of the dispenser container is that the pressurized product remaining in the delivery channel continues to be pressed out in small amounts in an uncontrolled manner after utilization despite the fact that the delivery valve is closed. In order to eliminate said disadvantage, the dispenser head (1) is configured with an additional closing device (1?) that automatically opens the delivery hole (3) and automatically closes it after the dispensing process is completed.

  • Patent number: 7028865
    Abstract: A dispenser for dispensing metered amounts of liquid or paste-like products has a cylindrical reservoir having an open bottom and an upper end with an intake valve. A plunger is arranged axially movably in the cylindrical reservoir and closes off the open bottom of the cylindrical reservoir. A dispensing head is arranged on the upper end of the reservoir. The dispensing head has a bell-shaped dispensing pump having elastic sidewalls and a pump head with a through opening having an outlet valve. The dispensing pump together with the intake valve and the outlet valve delimits a closed pump chamber. The outlet valve is manufactured as a monolithic part of the pump neck such that with a simple working step the entire through opening of the pump neck is closable by a valve flap of the outlet valve.

  • Patent number: 6968981
    Abstract: A dispenser for distributing measured quantities of fluid to pasty product comprising a storage container with axially displaceable guide pistons and a dispenser head with a dispenser pump. A pump chamber is restricted by check valves at the entry and exit. A discharge channel is positioned downstream of the dispenser pump with an application opening that can be sealed by a sealing element. The dispenser head is designed with an application cap with a planar application surface closing the dispenser head in an axial direction and with an application opening centrally arranged in the application surface. The sealing element is designed in such a way, and arranged within the application surface, that the sealing element completely overlaps the application opening and is flush with the planar application surface.

  • Publication number: 20050139620
    Abstract: Container closures, for dispensing liquid to pasty products from flexible storage containers such as bottle or tubes, are known, which open independently for the discharge of the products on squeezing the storage container and then independently reseal as a result of the restoring force of the storage container. According to the invention, a complete ventilation of the storage container after finishing the discharge process and closing the container closure may be achieved whereby the container closure (1) is made from a housing (5) with an axially displaceable elastic annular disc (2) and a sealing stop (3) centrally arranged beneath the above, whereby stop ridges (6) are arranged in the housing (5) to limit the downward axial movement of the annular disc (2) and the upward axial movement of the sealing stop (3).

  • Patent number: 6880731
    Abstract: A dispenser head of a dispenser for dispensing metered quantities of liquid and pasty products with spherically encapsulated components includes a dispenser pump and a dispenser duct with applicator opening following the dispenser pump for metered dispensing of products, wherein the dispenser pump includes an inlet duct and an outlet duct and a pump chamber closed at the inlet and outlet sides by check valves. At least one screen-like perforated mask is arranged in the product flow from the pump chamber during the dispensing procedure toward the outlet side, such that the entire product quantity must pass through the perforated mask during the dispensing procedure.

  • Patent number: 6321908
    Abstract: A multi-chamber container comprises a first container for receiving a first product component and a second container for receiving a second product component, the containers being rotationally coupled with one another and each comprising a communication opening for the mutual exchange of the products. Moreover, a closing device is provided for simultaneously closing the two communication openings, the closing device comprising an engaging device for introducing the rotational movement of one container into the closing device, and the closing device further comprising guide devices which are coupled to the other container, such that upon rotational movement the closing device is moved into a position of releasing both communication openings.

  • Patent number: 6240979
    Abstract: The present disclosure relates to a method of filling a dispenser and to the dispenser itself. For already filling a defined part of the head piece (20) when mounting the dispenser after material has been filled into said dispenser and for ensuring an interruption-free dispensing behavior during future operation, it is suggested that, when a first point of airtight sealing of a fluid container (10) by means of a head piece (20) has been reached, the movement of the two elements towards one another should be continued along a predetermined, fixed displacement distance (X). In addition, a dispenser is provided, especially for carrying out the filling method, in which a bottom side of the head piece (20) and a filler opening of the fluid container (10), which is adapted to be coupled to said bottom side, are implemented such that they match.
