20100012678 | CONTAINER UNIT FOR THE STORAGE AND PROTECTION OF LABORATORY SUBSTANCES - A container unit for the storage and protection of laboratory substances includes a protective housing and a dosage-dispensing unit. To make the dosage-dispensing unit ready for use, the protective housing is removable. As a means to optimize the simplicity and safety of handling the unit and to achieve the required protection for the laboratory substance contained in it, at least one chamber is formed in the protective housing and filled with a treatment agent. The at least one chamber has a passage opening directed towards the interior space, with a chamber closure element allowing the passage opening to be closed gas-tight. The treatment agent inside the chamber can preferably be filled into the chamber and sealed off gas-tight with the chamber closure element already during the process of manufacturing the protective enclosure. | 01-21-2010 |
20100051648 | DOSAGE DISPENSING DEVICE FOR POWDERS AND PASTES - A dispensing head for a powder or paste dosage material has a housing with an outlet opening, a bearing- and passage area, and at least one socket connected to a source container. A feeder chute is formed inside the housing. A closure shaft is in the bearing- and passage area, free to rotate about and to slide along its central longitudinal axis. The closure shaft is connected to a closure element arranged near the outlet opening. Moving the closure shaft in the axial direction controls the volume flow of the dosage material through the outlet opening. A limit stop restricts the displacement of the closure shaft along its central longitudinal axis. In the feeder chute, an opposing stop defines the closed position where the limit stop rests in direct contact against the opposing stop and the outlet opening is closed off by the closure portion of the closure element. | 03-04-2010 |

20110192491 | RECEPTACLE FOR WEIGHING PRESCRIBED TARGET QUANTITIES OF SUBSTANCES - A receptacle for the weighing-in of free-flowing substances has a fill opening, a tubular-shaped circumference wall, and a bottom part. The bottom part is connected to the tubular-shaped circumference wall, which it tightly closes off in the direction of gravity when the weighing receptacle is in its operating position. The weighing receptacle can be set on the weighing pan of a balance and can be filled like a beaker with free-flowing substances without allowing the latter to escape therefrom. The bottom part can be opened either by an outside force acting on the weighing receptacle and/or through the influence of a solvent acting on the weighing receptacle, forming an outlet orifice in the bottom part. The weighing receptacle, otherwise tightly sealed in the direction of gravity, can be flushed out with a fluid when the outlet orifice is opened. | 08-11-2011 |
20110204088 | DOSAGE-DISPENSING DEVICE WITH A CHANGING MECHANISM FOR DOSAGE-DISPENSING UNITS - A device for dispensing a dosage includes a base frame, at least one device for receiving any dosage-dispensing unit or functional unit that is compatible to be inserted therein, a holder and at least one drive mechanism. The holder has at least one holding position for a dosage-dispensing unit or functional unit. A weighing cell arranged on a lower horizontal plane of the base frame includes a load receiver to receive a target container. A changing mechanism enables the receiving device to be moved horizontally relative to the base frame. This horizontal shift allows a dosage-dispensing unit or functional unit to be interchanged between the holding position and the receiving device. The changing mechanism also permits the receiving device, together with the drive mechanism, to be moved vertically with regard to the base frame. | 08-25-2011 |
20110220686 | DOSAGE-DISPENSING UNIT FOR FREE FLOWING SUBSTANCES - A dosage-dispensing head has a body with an end surface and an area that couples the head to a source container. The end surface has an outlet opening connected to the coupling area. The head also has a slider, constrained to a guided linear sliding movement parallel to the end surface. An aperture-setting member of the body turns about a rotary axis, orthogonal to the end surface, to actuate the slider. An orifice opening of the aperture-setting member is configured so that the outlet opening is always within the area of the orifice opening. A passage opening of the slider is between the body and the aperture-setting member. By turning the aperture-setting member, the slider moves in a linear path, linearly displacing the passage opening relative to the outlet opening and varying the aperture width of the dosage-dispensing head. This regulates the flow rate of the free-flowing dosage material. | 09-15-2011 |

At least two defined functional positions that can be aligned with at least one container platform which is arranged in the work compartment. The first functional position contains a receiving device which serves to hold a dosage-dispensing device with free-flowing dosage material, and each of the other functional positions contains an additional device. At least one of the protective walls has a cutout opening, and the at least one multifunctional work head is arranged partially in the cutout, so that portions of the at least one multifunctional work head lies both inside and outside of the work compartment. | 11-24-2011 |
20120132317 | DOSAGE-DISPENSING DEVICE - A dosage-dispensing unit with an interior space, delimited by a lateral wall and a bottom portion. The bottom portion further includes an outlet orifice.

The outlet orifice has a central longitudinal axis that is oriented at a predetermined angle relative to this prescribed direction of movement. The internal surface of the bottom portion facing towards the interior space includes a surface region having at least a line segment that starts at the outlet orifice and extends in the prescribed direction of movement. | 05-31-2012 |
