A container for holding a product including a holding means for removably holding a product measuring device adjacent the upper end of the container. The holding means is connected to the container and the measuring device may be replaced in the holding means to secure the measuring device therein during use of the product.

A liquid level detection method includes capturing an image of a liquid surface, a structural surface, and graduation markings provided on the structural surface using an image-capturing device to thereby obtain an initial image. Subsequently, the initial image is processed so as to generate a processed image, and a level reference value of the liquid surface is obtained from the processed image. The level reference value represents a height of the liquid surface in terms of inherent characteristics of the processed image. Lastly, a liquid level of the liquid surface is calculated based on a relative proportional relation among the level reference value, an overall height of the processed image in terms of the inherent characteristics of the processed image, and dimensions of any one of the initial and processed images relative to the graduation markings.

A dispensing utensil 10 comprising: a handle portion 11 having a first end portion and a second end portion and a frangible connection intermediate the first and second end portions; an implement portion 12; a cavity 15 for storing dispensable contents, the cavity 15 defined by a first wall means 13, 14 and a second wall means 19 closing the cavity 15; characterized in that a first portion 20 of the first wall means 13, 14 is openable about a hinge formed by the second wall means 19, thereby allowing the contents to be dispensed.

Devices and methods for depositing fluids on substrates in patterns of spots, lines, or other features use a nozzle, which is preferably configured similarly to a micropipette, having a piezoelectric crystal or other ultrasonic actuator coupled to one of its sides. The nozzle may be charged via capillary action by dipping it into a well containing the fluid to be deposited, and may then be positioned over a desired area of a substrate, at which point activation of the ultrasonic actuator at ultrasonic frequencies will eject the fluid onto the substrate. The needle may subsequently be dipped into a well of rinsing fluid for cleaning. Spots or lines on the order of 5 micrometers width may be generated, making the invention particularly suitable for use in biological applications such as microarray production and in microelectronics applications such as the printing of organic circuitry.

The present invention provides an improved apparatus for measuring and dispensing powdered products. The apparatus includes a cup portion and a funnel-shaped dispenser. The cup holds the powdered material to be measured is sized to contain a desired volume of the powder when filled to its upper edge. The upper edge of the cup has a flat surface to accommodate leveling of the powdered ingredients. The funnel-shaped dispenser serves as a leveler and aids in accurately dispensing the measured powder into a mixing area. The funnel-shaped dispenser thus defines a flat edge at its receiving opening for engaging the upper edge of the cup.
