Problems solved by technology

While the device is effective for some uses, such as dispensing laundry room stain remover, it is less than ideal for dispensing caustic chemicals that can irritate or injure a person's skin when exposed to them as the user's hands very close to the assigned opening

Embodiment Construction

[0016] In one embodiment, the dosing device of the present invention precisely dispenses a predetermined amount of liquid when a push button is actuated with finger pressure. The liquid flows by gravity from the metering chamber into a container where it can be diluted with water or another liquid. When the metering chamber is empty, a user can reset the device, which allows the metering chamber to refill. The device can be used to dispense various types of liquids, including cleaning solutions, medications, cleansers, food, mouthwash, and pharmaceuticals. The above and other features of the invention are described in more detail below.

[0017] figure 1 4 to 4 show an embodiment of a dosing device 100 according to the invention. It comprises a main chamber 105 formed by a body 110 and a cover 120 , and a metering chamber 115 in the lower part of the body 110 . The main chamber includes an upper opening 125 and the metering chamber includes a lower opening 135 . Cover 120...

Abstract

A dosing device is described, in which a predetermined amount of a material such as a concentrated fluid can be dispensed from the device by finger pressure. In one embodiment, the device includes a shuttle that can move between first and second positions. In the second position, fluid can escape from a dosing chamber.

Description

technical field [0001] The present invention relates to a device for dispensing weighed doses of material, such as a concentrated liquid chemical composition. Background technique [0002] Some liquids are sold in concentrated form, which can be diluted with water before use. One example is dish soap, which is diluted with water and dispensed in a spray bottle or from a pail or can and applied to the surface to be cleaned. Concentrated liquids are far less expensive to transport and store than pre-mixed liquids and have gained wide acceptance in the food industry, property supply and building materials industries. [0003] However, using concentrated liquids is not without its problems. If too much liquid concentrate is used, the cost per use is higher than normally required. If too little concentrate is used, the resultant mixture may not be as good to use, possibly causing the user to use or apply more of the mixture than is intended to work better. Therefore, accurate...
