Embodiment Construction

[0041] see now Figure 1-11 , shows a preferred embodiment of a fluid dispensing system, the system includes a fluid dispenser assembly 12 and a bottle 14 containing some of the fluid to be dispensed. Fluids are typically provided in concentrated form, with the intent to dilute the concentrate with at least one other diluting fluid prior to dispensing and use. The concentrate in bottle 14 may be any of a wide variety of substances, such as cleaners, solvents, disinfectants, insecticides, herbicides, and the like. The diluent can be water or any other suitable fluid. Dispenser assembly 12 is generally constructed in accordance with US Patent No. 5,425,404.

[0042]The bottle 14 of the present invention includes a valve cap 16 for controlling the dispensing of the concentrate in the bottle 14 . During use, bottle 14 with valve cap 16 cooperates with dispenser assembly 12 to dispense and dilute the concentrate. More specifically, bottle 14 is inverted into Figure 3-11 As sh...

Abstract

A dispensing valve cap mountable to a bottle is provided with a first valve part having a tubular portion having an air inlet, the first valve part further including a fluid outlet spaced apart along a longitudinal axis of the tubular portion to form a constant head valve for dispensing fluid from the bottle. A second valve part of the valve movably mounted to the first valve part includes a tubular portion for simultaneously closing both the air inlet and the fluid outlet of the first valve part when fluid dispensing is not desired. The second valve part further includes an air inlet alignable with the air inlet of the tubular portion when fluid dispensing is desired. The dispensing valve cap controls fluid flow from the bottle. The bottle with the valve cap is useable with a dispenser assembly for mixing a concentrated fluid from the bottle with a dilutant. A tamper resistant lock prevents undesired rotation of the second valve part relative to the first valve part. The tamper resistant lock is deactivated upon insertion of the valve cap into the dispenser assembly.

Description

technical field [0001] The present invention relates generally to systems for dispensing fluids, and more particularly to valve caps and bottles for use in gravity-fed fluid dispensing systems. Background technique [0002] Known gravity-fed fluid dispensing systems are used to dispense concentrated fluids for mixing with diluents. An example of such a system is US Patent No. 5,425,404, "Gravity Feed Fluid Dispensing System," issued June 20, 1995 to 3M Company, St. Paul, Minnesota. US Patent Nos. 5,435,451 and 369,110, issued to 3M Company on July 25, 1995 and April 23, 1996, respectively, relate to a bottle for use in the gravity-feed fluid dispensing system of US Patent No. 5,425,404. [0003] The gravity-fed fluid dispensing system of US Patent No. 5,425,404 generally includes an inverted bottle containing the concentrated fluid, the bottle having an opening closed by a valve cap. The system also includes a dispenser assembly which cooperates with the bottle and valve c...
