Abstract: An insert for use with a flexible liquid bag, having upper and lower ends, with the upper end of the bag having a hollow support structure with open upper and lower ends, mounted in an opening formed in the bag adjacent the upper end of the bag. The insert has open upper and lower ends with the lower end of the insert being received by the open upper end of the hollow support structure. A normally closed valve structure is positioned in the insert to prevent liquid from flowing therethrough. An actuator cap is threadably mounted on the upper end of the insert. The actuator cap includes structure to open the normally closed valve so that liquid in the bag may flow through the insert. The bag with the insert secured thereto will be inverted in use so that the liquid will flow downwardly from the bag.

Abstract: An automatic detection system is provided for detecting disruptions in the flow of liquid from a liquid container or containers to a dispensing apparatus. Two embodiments of the system are disclosed. In the first embodiment, a single liquid container is utilized. In the second embodiment, two liquid containers are utilized. In both embodiments, an optical sensor is employed to detect a disruption in the flow of liquid from the liquid containers to the dispensing apparatus.

Abstract: A tamper-proof insert for use with a liquid container. The insert is of the foam liner venting type. The insert is designed to be inserted into the throat of a container such as a bottle. A retention lug ring is secured to the lower end of the insert. The retention lug ring includes a plurality of spaced-apart retention lugs, having upper and lower ends, which extend upwardly and outwardly from a base ring. The upper ends of the retention lugs of the retention lug ring engage the inside surface of the container to prevent the insert from being manually pulled upwardly and outwardly from the throat of the container. If the insert is pulled from the container against the resistance of the retention lugs, the lugs will break-away from the insert and it will be evident that the insert has been subjected to tampering.

The insert is designed to be inserted into the throat of a container such as a bottle. A retention lug ring is secured to the lower end of the insert. The upper ends of the retention lugs of the retention lug ring engage the inside of the container to prevent the insert from being manually pulled upwardly and outwardly from the throat of the container. If the insert is pulled from the container against the resistance of the retention lugs, the lugs will break-away from the insert and it will be evident that the insert has experienced tampering.

Abstract: An automatic detection system for detecting disruptions in the flow of liquid from one more liquid containers to a dispensing apparatus. If the system detects an interruption of the flow of liquid to the dispensing apparatus, a visual alarm, an audio alarm, or a data alarm is activated. Three embodiments of the system are disclosed.

Abstract: An apparatus for rinsing inverted chemical containers includes two main assemblies, namely a gravity flow valve assembly and a rinse adapter assembly. The gravity flow assembly is inserted into the throat of the container. The rinse adapter assembly is detachably secured to the throat of the inverted container. When the rinse adapter assembly is attached to the throat of the container, the rinse tube of the rinse adapter assembly extends upwardly through the gravity flow valve assembly and into the interior of the container. Rinsing fluid, such as water, is supplied to the rinse tube which sprays the rinsing fluid onto the interior of the container to rinse the chemical residue from the interior of the container. The apparatus may also be used to dilute the liquid chemical in the container so that the diluted chemical will more freely drain from the container.

Abstract: A hand-held dispenser for precisely controlling the flow rate of water therethrough and for injecting a liquid chemical into the water passing through the dispenser. The dispenser includes a slide valve for changing the flow rate of the liquid chemical water therethrough. The slide valve may also be positioned so that only rinse water is discharged from the dispenser.
