Abstract
When dispensing a flowable substance from a container by way of a motor driven dispensing device, for ensuring that the container is properly inserted into the device, that the substance is still usable and/or that the dispensing speed is selected in accordance with the viscosity or other properties of the substance, the container is provided with a marking which may be stored in a transponder provided at a front container cap. When the container is properly inserted into the dispensing device, the transponder cooperates with a sensor disposed in an end wall of the device for enabling and/or controlling the dispensing mechanism on the basis of the characteristic data detected.
Claims14
A device for dispensing flowable substances, comprising a housing for receiving a container containing the substance and having a marking element, and means for emptying the container,
- wherein the housing includes detecting means for detecting the marking element, the detecting means controlling the dispensing device in response to the output signal of the detecting means, and
- wherein the marking element is contained in an electronic circuit chip provided on the container and the detecting means includes a processor adapted to be placed in contact with the chip.
A device for dispensing flowable substances, comprising a housing for receiving a container containing the substance and having a marking element, and means for emptying the container,
- wherein the housing includes detecting means for detecting the marking element, the detecting means controlling the dispensing device in response to the output signal of the detecting means,
- wherein the marking element is related to the spatial position of the container and the detecting means controls the dispensing device in response to the position of the marking element,
- wherein the detecting means differentiates between a rest position in which there is no container in the dispensing device, a working position in which a container including the marking element is in the proper position within the dispensing device, and an abnormal position in which the marking element is in a position indicating an improper position of the container in the dispensing device, and
- wherein the marking element is provided on a part which is displaceable in response to the internal pressure of the container.
A device for dispensing flowable substances, comprising a housing for receiving a container containing the substance and having a marking element, and means for emptying the container,
- wherein the housing includes detecting means for detecting the marking element, the detecting means controlling the dispensing device in response to the output signal of the detecting means,
- wherein the marking element is related to the spatial position of the container and the detecting means controls the dispensing device in response to the position of the marking element,
- wherein the detecting means differentiates between a rest position in which there is no container in the dispensing device, a working position in which a container including the marking element is in the proper position within the dispensing device, and an abnormal position in which the marking element is in a position indicating an improper position of the container in the dispensing device,
- wherein the detecting means is a sensor for sensing the marking element in a non-contacting manner and detects the marking element passing through the working position when the container is inserted into the dispensing device.
A device for dispensing flowable substances, comprising a housing for receiving at least two containers each containing one substance and having a marking element, a mixer and means for emptying the container,
- wherein the housing includes detecting means for detecting the marking element, the detecting means controlling the dispensing device in response to the output signal of the detecting means, and
- wherein the mixer is provided with a marking element and the housing is provided with means for detecting the marking element.
A device for dispensing flowable substances, comprising a housing for receiving a container containing the substance and having a marking element, and means for emptying the container,
- wherein the housing includes detecting means for detecting the marking element, the detecting means controlling the dispensing device in response to the output signal of the detecting means,
- wherein the marking element is related to the spatial position of the container and the detecting means controls the dispensing device in response to the position of the marking element,
- wherein the detecting means differentiates between a rest position in which there is no container in the dispensing device, a working position in which a container including the marking element is in the proper position within the dispensing device, and an abnormal position in which the marking element is in a position indicating an improper position of the container in the dispensing device, and
- wherein the marking element includes a reflecting mark and the sensor is a light barrier and detects the marking element passing through the working position when the container is inserted into the dispensing device.
A device for dispensing a flowable substance, comprising
- a housing for receiving a container containing the substance and having a marking element related to a spatial position of the container,
- means for emptying the container, and
- detecting means for detecting the marking element and controlling the dispensing device in response to an output signal of the detecting means,
- wherein the marking element is provided on a part which is displaceable in response to internal pressure of the container.
A device for dispensing a flowable substance, comprising
- a housing for receiving a substantially cylindrical container containing the substance and having a marking element,
- means for emptying the container, and
- detecting means for detecting the marking element and controlling the dispensing device in response to an output signal of the detecting means,
- wherein the container is adapted to be inserted into a container receptacle of the housing transverse to its longitudinal axis, the marking element being provided on an end face of the container extending transverse to said longitudinal axis, and the detecting means being disposed on a wall of the housing opposite said end face.
A device for dispensing flowable substances, comprising
- a housing for receiving a substantially cylindrical container containing the substance and having a marking element,
- means for emptying the container, and
- detecting means for detecting the marking element and controlling the dispensing device in response to an output signal of the detecting means,
- wherein the container is adapted to be inserted into a container receptacle of the housing transverse to its longitudinal axis, the marking element being provided on a surface of the container extending parallel to said longitudinal axis, and the detecting means being disposed on a wall of the housing opposite said surface.
