Disclosed herein are embodiments of liquid dispensing container preferably configured as portable, handheld liquid dispensing containers. These liquid dispensing containers possesses a vent structure that provides improved liquid dispensing along with simplified vent construction and container integration. In these regards, these liquid dispensing containers advantageously overcome one or more shortcomings associated conventional liquid dispensing containers and other types of containers.

A filler neck adaptor for use with manually operated fuel dispensing nozzles. Adaptor provides a visual cue that a target fuel level in the tank has been reached during tank filling operations. Adaptor comprises a flanged extension tube with an overflow reservoir sealed to the upper surface of the flange. A slidably adjustable securement ring is mounted on the extension tube. The securement ring is designed to mate with tank closure features on the filler neck. An airlock tank seal is installed on the lower surface of the securement ring to establish a seal between the securement ring and the tank filler neck. During filling displaced air in the tank is forced to exit the tank via an air vent passageway between the nozzle and the inside surface of the adaptor extension tube. As the rising fuel level in tank nears the distal end of the extension tube, wisps of fuel becomes entrapped in the airstream and become visible in the transparent overflow reservoir. This visual cue that the tank is full allows the operator to stop fuel flow prior to overflow spillage.

An example fluid container fill indicator system generates an alert in response to a change in pressure at the exhaust conduit or the fluid container. In some example, the change in pressure causes a reed or whistle type device to generate an audible alert. In some examples, the alert is a mechanical and/or electronic signal based on a change in position or orientation of a valve in response to the change in pressure.

Ullage float assemblies for fuel tanks are disclosed including a guide member with a retaining element mounted to a valve body which includes a first valve port and a second valve port in fluid communication. Methods of preventing spillage of fuel from a fuel tank during a refueling and a diurnal fuel volumetric expansion event are also disclosed. The assemblies and methods.

An underground storage tank maintenance system includes a system of monitors to determine pressure and humidity in the system. Inert gas may be supplied into the ullage of the tank. The inert gas may first pass through an interstitial space as between the primary storage and secondary containment, and then passed into ullage to capture contaminants on the way out of the vent to atmosphere. The system and method prevent hydrocarbons exiting to atmosphere. Humidity sensors may be set along vent to determine water contamination and trigger drying cycles. Pressure readings help identify system leaks.

Machine (1) for distributing a product stored in a container (30) comprising a storage zone (2) delimiting locations (4) for housing a container (30), a metering station (5) delimiting a chamber (6) housing a support (7) for accepting a collecting vessel (33), this support (7) being positioned vertically in line with an opening (8) providing access to the chamber (6), which opening is arranged in an upper part (61) of the chamber (6), the machine (1) further comprising a system (10) for emptying each location (4) for housing a container (30) through the opening (8) providing access to the chamber (6), and a unit (14) for controlling the machine (1). The metering station (5) comprises a sensor (13) for detecting the presence of a collecting vessel (33) inside said chamber (6). The control unit (14) is configured to operate the machine (1) on the basis of data supplied by said sensor (13), and the metering station (5) is equipped with a circuit (15) for the circulation of gaseous fluid providing communication between the chamber (6) and the outside of said chamber (6) through a forced circulation of air.

An electric oil pump with an one-way valve is provided, which includes a control box. The control box is provided with a communication pipe and a control board, one end of the communication pipe is connected with an oil-extracting pipe, the other end is connected with an oil outlet pipe, a pump body is arranged in the oil outlet pipe, and a bottom of the control box is rotatably installed with a threaded cap. When the oil pump is, working, the gasoline is blocked by the one-way valve and transported to the oil outlet pipe via the oil-extracting pipe during the oil delivery process, and the negative pressure in the oil drum makes the outside air enter into the oil drum through the one-way valve when the oil pumping is completed, so as to maintain the pressure balance between the inside and outside of the oil drum.

A tank container for bulk storage of liquid materials is provided with with remote operated valves. The tank container comprises a storage vessel for bulk storage of liquid materials and having a height of about eight feet. The storage vessel includes an outlet valve proximate a bottom of the vessel, a fill valve at a top of the vessel, and a vent valve at the top of the vessel. A parallelepiped frame surrounds and is secured to the storage vessel for stacking and transporting of the tank container. A fill line includes an outlet connected to the fill valve and extending downwardly within the frame and an inlet proximate the bottom of the frame. A fill valve actuator is mounted proximate the bottom of the storage vessel mechanically linked with the fill valve for operating the fill valve remote from the top of the storage vessel. A vent valve actuator is mounted proximate the bottom of the storage vessel mechanically linked with the vent valve for operating the vent valve remote from the top of the storage vessel.

A liquid container, meeting all federal, state and local regulations, comprising a vessel with an opening and a self-venting spout which is mounted to the vessel in a manner allowing the spout, from a stowed position, to rotate into its operational position and coupling to the opening with a coupler. Both open ends of the spout are automatically covered when stowed. A valve assembly at the opening of the vessel is operated externally by a trigger located near the underside of the primary handle. The valve assembly controls flow of liquid out of the vessel and through the self-venting spout. Venting of the vessel is allowed through a series of channels, respectively comprising an interior channel within the spout, an intake port, and an intake channel leading to the rear of the vessel above the liquid line. The vessel opening is covered by a lid mounted to the vessel that rotates into operational or stowed position and is sealed by the coupler.
