Abstract:
A pipetting device including a pipetting unit (12) having an application chamber (26) and a first end (16) that is realized with a discharge opening (18), and a second, open end (20). In the vicinity of the second, open end (20) of the pipetting unit (12), a sleeve-like receptacle unit (14) is guided so that it can move axially on at least two sealing lips (22, 24) that project radially inward and are at some distance from each other, which is provided on the side facing the application chamber (26) of the pipetting unit (12) with a base element (28), and on the side facing away from the application chamber (26) has an opening (32) and which has, in the vicinity of its periphery, at least one opening (34), the axial dimensions of which are somewhat smaller than or equal to the distance between the sealing lips (22, 24). The receptacle unit (14) can be moved with respect to the pipetting unit (21) from a closed position into an activation position, in which an interior (36) of the receptacle unit (14) is in communication via the at least one opening (34) of the receptacle unit (14) with the application chamber (26) of the pipetting unit.
Abstract:
A disposable dispensing device for liquid, paste and other flowable or free-flowing materials, includes a fillable and sealable plastic enclosure (12) with an absorption section (16) having a storage compartment (18) and a sealing section (20). The sealing section (20) is separated from the absorption section (16) by means of a tear seam (22). A fitted applicator (14) and a channel (40) for dispensing the material from the plastic enclosure (12). A sealing device (38), which closes the channel (40), is molded to the applicator (14) by means of a separating section (42) forming part of the sealing section (20) of the plastic enclosure (12). In order to dispense the material through the channel (40) of the applicator (14), the sealing device (38) can be detached from the applicator (14) by means of the separating section (42).
Abstract:
An applicator device for a free-flowing substance includes a carrier body provided with an application device at one end and a pin at an opposing end. A transverse channel penetrates the pin, and an axial channel branching off from the transverse channel leads to the application device. A reservoir device having a ring-shaped edge seal sealingly engages the pin, whereby the applicator device is activated by displacing the reservoir device on the pin toward the application device to open a flow connection between the reservoir device and the transverse channel. The reservoir device has a receptacle segment that is elastically deformable at least in portions so that, when the applicator device is activated and a flow connection between the transverse channel and the receptacle segment exists, the free-flowing substance is discharged via the application device by manual compression of the elastically deformable area of the receptacle segment.
Abstract:
A device for the storage and extrusion of a flowable substance (A) includes a loading unit (13) for an application tool (14). The loading unit has a pot-shaped insert (15) for a holder (17). Through axial pressure on the holder (17) the flowable substance A can be extruded from a chamber (12) of the holder through openings (20A) made on the perimeter of the insert (15) into a chamber (16) of the loading unit (13), so that the application tool (14) set at right angles to the axis of the insert (15) is loaded with the substance (A).
Abstract:
A multi-chamber ampoule for measured doses of liquids, which has an outer sleeve (2) of elastic material which on the inside has a first chamber (12) which extends along an axis (y) and is closed off by a first bottom (31) at the lower end. A closing element seals the outer sleeve (2) at its head end and has a micro brush (1) which at its tip (10) has a flocculus (11) capable of absorbing a liquid. The micro brush (1) is positioned in an inner sleeve (3) which can be moved inside the outer sleeve (2) in the manner of a plunger.
Abstract:
A multichamber ampoule with a locking and dispensing mechanism to store several substances and to dispense a mixture consisting of several substances, possessing a multiple-plug closure (140) with several plugs to selectively close and open several outlet openings in the multichamber ampoule, and an adapter (130) for mixing the substances and dispensing the mixture, wherein the multiple-plug closure (140) and the adapter (130) are connected to each other in an assembly designed to be removed from the multichamber ampoule (FIG. 23).
Abstract:
An improved prefilled, telescoping ampoule device having a simplified construction allows for passage of fluid from one component to the other without leakage. The telescoping ampoule device can be manufactured and assembled in an efficient manner and provides for adaptation to various application purposes without a change of basic design.
Abstract:
A multichamber dispensing device for dispensing a mixture consisting of a plurality of substances includes a receptacle unit (10) with several chambers that are aligned parallel in relation to each other. Each chamber has an open first end for inserting a piston and a second end having an outlet opening. A dispensing unit (30) including a dispensing channel and an adapter section (36) is connected to the receptacle unit (10). The adapter section includes at least one detachable separating element (38) which protrudes radially to the inside and interacts with at least one locking means of the receptacle unit (10), so that after loosening the separating element (38), the dispensing unit (30) opposite the receptacle unit (10) can be shifted in an axial direction.
Abstract:
A single-use dispensing device for dispensing liquid, pasty and other flowable and fluid substances includes a fillable and sealable plastic container for receiving a substance. The container has a neck end, a filling end opposite to the neck end, and lateral sealing seams defining a lateral contour of the container. An opening provided in the neck end extends through the neck end for dispensing the substance. A plug-like closure means for closing the opening extends throughout the neck end toward an outer portion of the neck end. A first transversal sealing seam extends transversely through the lateral sealing seams of the container at the outer portion of the neck end sealing the closure means from all sides. A tearable perforation seam provided in a portion of the neck end extends transversely through the lateral sealing seams. The perforation seam being displaced relative to the first transversal sealing seam towards the filling end of the container.
Abstract:
A device for retaining and dispensing a free-flowing substance includes a syringe-like retaining body (12) in which a retaining space (46) is formed. A displaceable piston (22) is axially introduced into the retaining space (46) and the retaining body (12) is provided with a dispensing nozzle (18) on its front end facing away from the piston (22). A locking pin (36) through which at least one transverse channel (44) passes, with an axial channel (42) branching off therefrom, is provided on the inside of the dispensing nozzle (18). In a closed position of the locking pin (36), a flow connection between the retaining space (46) and the transverse channel (44) is blocked. In an activation position of the locking pin (36), the transverse channel (44) is connected to the retaining space (46), so that the free-flowing substance can be dispensed from the retaining space (46) via the transverse channel (44) and the axial channel (42).
